English Paper Final - Essay Example A Marxist society is always in a process of being created, and this occurs through communication and negotiation (Giddens et al, 2003). When the family breaks down, these important functions no longer occur. Social order becomes confused either because they were never understood to begin with under the functionalist perspective or because there is no communication or negotiation under the Marxist perspective. This sort of breakdown can be discovered in many recent examinations of American family life such as that included in Katie Arnoldi’s fictional novel The Wentworths. As is shown in The Wentworths, for reasons of pride or competition, today’s society typically allows for little real connection between family members which makes it difficult for us to truly communicate with one another. Katie Arnoldi’s book tells the story of a small family in Southern California struggling to overcome the division and dissension of the postmodern lifestyle. Although the family is not the worst family to be found anywhere, it is highly dysfunctional. The Wentworth family consists of August Wentworth, who is an aging man who has always been something of a playboy and is only just beginning to recognize that this lifestyle is no longer fulfilling. August is married to Judith, who has become obsessed with keeping her body looking like a 20-year-old despite the fact that she has three children already well past that age and with keeping everything exactly the same. At one point in the book, her entire day is destroyed because of a missing pair of silver serving tongs that are not where they belong. August and Judith have three adult children. The oldest is Conrad, who remains single and is a high-powered lawyer in L.A. He also is sexually deviant, engaging in masochistic activit ies and consistently choosing to sleep with women who resemble his mother. Becky is the

England In the years 1067-1075 Essay Example for Free

England In the years 1067-1075 Essay a) How far do these sources support the view expressed in source one that, in the years 1067-1075, William had favoured conciliation in his attempts to establish peace in England? The view of William I favoring conciliation in his attempts to establish peace, to a certain extent, do agree with a number of the sources. This is only to a degree due to events that occurred between the years 1067 and 1075 that pushed William into more brutal and violent methods of subduing the English and securing his authority over England. Sources that do agree with William I using peaceful procedures to establish peace are sources three and four. Both sources to a great extent agree with the first source. Source three depicts how appeasement established authority. The source describes the naval and land levies, proving that William favoured conciliation. William had enough trust with the English to take them to war with him, and that they would not mutiny. This trust can be linked with source four; William felt strong enough to leave England in the hands of William fitz Osbern and go to Normandy. However, did the English really have a choice? With the erection of castles, the use of cavalry, and Norman landholders, the English may have been forced to fight for him; there is little detail of the events or others before or after. Source four also agrees, for throughout the duration of the documents Lanfranc negotiates peacefully with Roger warning him of the seriousness but giving him a second chance. Lanfranc assures him, of safe conduct, and to give the earl what help he can, saving his allegiance. The source is limited due it being correspondence over just the year 1075. Before and after this date other issues may have aroused, and the letters are not written by William I but by Lanfranc1 who was a very trusted friend to William. However, though acting on the Kings behalf, of appeasement, Lanfranc would have used his own ideas and thoughts on the case. Finally, as Hereford was the son of William fitz Osbern, he could have been treated differently for his links with William I; they were friends from their childhood2. Source two and five disagree with the statement in source one. Source two is from the Anglo-Saxon Chronicle3; as a consequence of the invasion, William is described to have devastated Yorkshire (Harrying of the North) 4 ravaged and laid waste to the shire. There is no implication of conciliation from William. Source two is inadequate due to it only covering one year, it does not take into account events outside of 1069. The Anglo authors of the chronicle could be biased towards the Normans, exaggerating the truth, leaving out appeasement by William I. Source five also disagrees with the statement recounting how William ruined Norwich, and blinded some of the traitors. The source is partial due to it covering only one date and the account of the situation is brief, and may exaggerate the Norman methods. The primary sources (source two, four, and five), overall, have an unbalanced view of William I and his tactics for establishing peace in England. The main drawback to most of the sources is the lack of facts during the years 1065 and 1075. This means that the revolts that occurred before 1069 are not mentioned. A final limitation, which I believe is the most key, is a list of rules that William I laid down when he first conquered England. The first rule was that above all things he (William) wishes one God to be revered throughout his whole realm, one faith in Christ to be kept ever inviolate, and peace and security to be preserved between English and Normans. Williams want, and favor towards peace is fully recognised in this statement. Foot Notes; 1. Lanfranc was, at the time, head of the new foreign bishops and abbots and also Archbishop of Canterbury. Lanfranc was unimpressed with the quality of the English clergy and during Williams reign supported his policy of promoting foreigners to high office in the Church. 2. William fitz Osbern, as a boy William I loved him above other members of his household. William I and William fitz Osbern were related, as fitz Osberns father was the grandson of Duke Richard of Normandys half-brother, Rodulf. Later on Roger Earl of Hereford had to forfeit his land and loose his title as Earl of Hereford. This though not brutal is not favoring conciliation by William I or Lanfranc (on Williams behalf). 3. The Anglo-Saxon Chronicle was for the years before and during the conquest of England the main source of evidence and information. There exist three versions: C, D and E, derived from a common source but with some differences. The chronicle supplies a uniquely English account of political events and allows us to make comparisons with the rather obvious Norman propaganda. 4. The Harrying of the North was in response, by William I, to the revolts occurring in the North (Yorkshire) during the years 1069-70. William had marched north with seasoned troops, devastating the countryside as they went, and slaughtering all the adult males. What his troops conflicted on the people was so terrible that chroniclers remembered it over fifty years later. In the Domesday book, made in 1086, it simply records Yorkshire as waste due to the brutality of William the land was depopulated, villages left deserted, farms empty, and this was fifteen years later. b) To what extent did the Revolts in the years 1069-75 aid William I to assist his Royal Authority in England? The revolts between the years 1069-75, to a great extent, aided William I to assert his royal authority across England. They provided William with the chance and excuse to use and show his military power. William was able to remove key Anglo-Saxon lords who posed a threat to him; build castles to maintain his control of the country; and it allowed him to firmly set, in the minds of the Saxons, that the Normans werent just invaders, like the Vikings, but conquerors of England. However, the revolts were not the only reason for Williams successful affirmation of royal authority on the country. William adopted methods of conciliation. He kept the Anglo-Saxon traditions such as sheriffs, shires, coronation rights and writs and added Norman culture and society on top to create an Anglo-Norman England. Before the revolts William was in a very exposed position. He had five thousand men to the two million Saxons, and he had no control of the North, West or East of England. Due to this vulnerability William was systematically peaceful in dealing with the Anglo-Saxons; using conciliation rather than consolidation. The revolts were essential to the change in Williams attitude towards the situation. He began to use brutal, ruthless methods to obtain his authority. The importance of the revolts depended on who was involved and the consequences of the revolt. Though there were minor revolts, when comparing them to revolts such as the Northern revolt (1069-70), they are taken into account to supply us, the historian, with a realistic overview of how dire Williams need was to obtain and retain royal authority. Rebellions began to inflame the country, in 1067 the Welsh border, lead by Eric the Wild, revolted in Herefordshire. Subsequently the south-west revolted in 1068, with the city of Exeter refusing to accept William as their King, and Harold Godwinsons sons attempted a counter invasion in the summer of 1068. Between the years 1069 and 1070 the North revolted. Rebels in the North burned to death a Norman Earl, Robert of Commines, in Durham. A Viking army of 240 ships, led by the sons of Swegn Estrithsson, landed at Humber and marched on York. They gained support from the local Saxons, and they seized York. Their success produced a domino affect sparking revolts in Dorset, Cheshire, Staffordshire and Somerset. William faced the possibility of a Scandinavian Kingdom in the north of England, or a separate Kingdom for Edgar, the last prince of the Royal House of Wessex. William reacted to these revolts with characteristic vigour, skill and utter brutality. He became the barbarous murderer of many thousands, both young and old, of that fine race of people1. The Welsh failed to take control of the border, and retired to Wales with much booty. Exeter, in the south-west revolt of 1068, was laid under siege for 18 days, by Williams troops, by which time they accepted William as their King. Harolds sons were repelled by Williams forces in the summer of 1068. William to counter-act this made a series of lighting raids through Warwick, Nottingham, York, Lincoln, Huntingdon and Cambridge to show his presence as the new King. In reaction to the revolts in the North, William marched North with troops from York and Nottingham, devastating the countryside, slaughtering all adult males and pillaging as he went, killing animals and burning crops. This was called the Harrying of the North and the destruction of the land was so terrible that when mentioned in the Domesday Book, 20 years later, it was classed as a waste land. From Yorkshire William pushed his men across the Tees in the winter and took Chester, and Stafford, and was back in Winchester before Easter 1070. Due to the revolts and the resulting victories for William, who had either killed or utterly suppressed the resistance, he had to enforce his power, and show that the Normans were the new rulers and would not leave. William accomplished this by first building motte-and-bailey castles across England. William began to erect them right at the start of his campaign, even before the battle of Hastings, and they were virtually unheard of in England. William built hundreds across England, to show the Normans strength and power over the population. This geopolitical process meant that they exerted control over the surrounding countryside. The Normans would demolish houses in the centre of towns to erect a castle. This happened in towns such as Cambridge, Lincoln and Dorchester2. These castles were, and still are, looming features over the landscape3. They were built in the centre of towns for economic reasons; the material or foundations of earlier fortifications (Roman/Saxon) were there already, and also it was cheaper to build on existing forts rather than building on top of a hill, having to transport supplies and food up it. Another affect of castles was their psychological affect on the Saxon population. Castles were a conspicuous emblem of Royal authority4, and were clearly statements of power to the indigenous people5. By the end of the revolts, 1075, William felt secure enough with his authority over England that he went back to Normandy and left his trusted advisor and Archbishop of Canterbury, Lanfranc in charge of the kingdom. Another factor which was opened up due to the revolts, and the success for William I, was the replacement of all the Anglo-Saxon earls. The earls were either dead from the revolts or just forced off their land. William strategically placed relatives or close friends to tenet the earldoms. For example Odo of Bayeaux, was earl of Kent and half-brother to William I. Also the new earl of Hereford, William fitz Osbern, was Williams cousin. This formed a tight, trustful network of family and friends which William could rely on. Another advantage to William of the revolts was it allowed him to fully assert royal authority on Anglo-Saxon church. William had to as, 30% of land in England was permanently owned by the church, bishops and abbots were literate, powerful men who advised the old Kings of Saxon England. If William could control the church he would be successful in his total control of England. William achieved this by removing 99% of all Saxon bishops, abbots and clergy, with Norman-French ones by 1087. William built new stone cathedrals, as a sign of domination, on top of old wooden Saxon churches. This had the same affect as the castles, showing the Norman supremacy over the Saxons. In 1070 the most powerful churchman in England, Stigand Archbishop of Canterbury, was deposed and replaced by Lanfranc, an Italian monk who was Williams greatest advisor. Three other important Saxon bishops were also removed, and also many abbots. Finally in 1072 Lanfranc gained superiority over the Archbishop of York, thus making Canterbury the chief church post in England. As Lanfranc had control over the North, this aided William with his control. In the 11th century, people were very suspicious and believed solely in the existence of God. These men of God, the bishops and abbots were trusted by the Saxon people no matter what race they were, even Norman, because of the risk it could cause them in the afterlife if they offended them. The extent of royal authority being asserted on England does not solely come from the revolts but also from Williams conciliation of the country, mainly before the revolts. Although the landscape of England had changed with the formation of castles, looming over the country and the mounted cavalry, trotting through the towns and villages, William I always governed through legal and rightful inheritance from Edward the Confessor with the use of Anglo-Saxon tools of government and traditions of kingship. When William came to the throne, December 25th 1066, he was crowned in the traditional Anglo-Saxon manner, like Edward the Confessor before. This showed his belief in tradition and proved his rightful claim to the throne. By using the ancient traditions of Anglo-Saxon kingship ceremonies alongside the unique circumstances that brought him the crown, William and his successors were able to appeal both to English customs and to the Norman sense of righteous conquest. William in the lead up to the revolts kept the country as it was, making no major changes and if any were made they would consist of a mixture of Anglo-Saxon and Norman customs. The main household after 1066 was not fundamentally changed. The only big difference in the household was that after 1066, and especially around 1087 (William Is death) the nobles were increasingly Norman. At first William kept some Anglo-Saxons in his household, one example was Regenbald, and he was the chancellor and was in command of the Royal seal under Edward the Confessor and William I. This shows Williams desire for continuity within the government, and only adding extras on top mixing the two cultures of the Normans and the Anglo-Saxons. The earldoms at the beginning of Williams reign did not change. They remained as the four large Earldoms of East Anglia, Mercia, Wessex and Northumbria. However, around the time of the rebellions against William I (1070s), William I granted the land to new nobles and tenants. As a result he and his two half-brothers owned 50% of England, the Church remained with around 30%, and roughly 12 barons (great lords) shared the remaining 20%. These 12 barons, basically like his half-brothers, were often related through hereditary or marriage to William. Kingship was very much affected by the character of the King on the throne at the time. So this was destined to change with the accession of William I. William I had to be physically strong, spending most of his time on the move (itinerant kingship). Also mentally strong to dominate the churchmen and the barons who all had their own ambitions and interests. With this change in kingship, William introduced a fairly new system of crown-wearing sessions. William I wore his crown and regalia where the people could see him. Three major times for this crown-wearing was Easter at Winchester, Christmas at Gloucester, and on Whitsun in Westminster. This new method and change in kingship could have been a sign of William Is security as King. However, William I could of used crown-wearing sessions for another reason, to state his claim and right to the throne, indefinitely, upon landholders, and the barons. This would agree with his use of the coinage system set up in England before 1066. William on his coins and seals had a picture of him sitting on the throne with all his regalia, on one side, and on the other him on a horse with a sword; William is declaring his claim to the throne, by right, and if that is not enough by force and bloodshed. William changed the iconography of kingship to add strength to his kingship. The chancery of pre-1066 was only slightly revolutionised. After 1066 the clerks, who wrote up the laws and grants began to progressively, under William, write the laws in Latin. Latin was the language of authority, the Norman nobles and the officials wrote in Latin. This language of power was fully founded around 1070. The use of clerks was not new to England. William I only adapted them to his cultural needs and desires. Also Latin was not known throughout the greater population. This causes supremacy over the plebs on the land, and dominates their lives. Sheriffs were the Kings official in a shire. These officials had been around before William. William I did not have sheriffs back in Normandy, and found them to be very useful. After the rebellions around the 1070s, sheriffs were increasingly Norman (as were the earls and bishops). The powers of the sheriffs increased hugely, and they were often in charge of royal castles (castellans) as well. Most Norman sheriffs were aristocrats who had much more wealth and power than the previous Anglo-Saxon sheriffs. A final instrument used by William I to completely assert his authority on the country was the production of the Domesday Book6. This book allowed the King to find out who had what and who owed what, twenty years after his seizure of the kingdom. The Domesday Book also shows us how sophisticated the Anglo-Saxon government was before the Normans. Without the shires, hundreds and sheriffs this type of census would have been near impossible to make. The Domesday Book is a record of a conquered kingdom, but it is a testament to the survival of the Anglo-Saxon government in many aspects. William I was aided by the revolts (1069-75) to a great extent. The revolts changed the King from conciliation to consolidation. However, the revolts, the castle building, the revolutionary change of the earldoms and the church, came, all, after the revolts. A new set of values had been introduced into England; these were based upon loyalty and military service. The government of the new king was based upon the traditional procedures and customs of Edward the Confessor but was enforced with a savage energy inspired by, mainly, the revolts between the years 1069-75.

Cambridge (27 houses were demolished), Gloucester (16 houses demolished), Lincoln (166 houses demolished), and in Dorchester (an area of 150,000 square metres was taken up). 3.

Types Of Mobility For Mobile Computing Computer Science Essay

Types Of Mobility For Mobile Computing Computer Science Essay The development in last 20 years in the field of telecommunication and the integration of telecommunication with internet has promised pervasive computing infrastructure. These pervasive systems allow users to access their information on the internet irrespective of their location. In addition, the advancement in devices miniaturization increases the number of portable devices connect to the internet like mobile phone, laptops, palmtops net books, PDAs, etc. In these scenarios we can consider different types of mobility. User mobility, Terminal mobility, Mobile access to resources.  ¿Ã‚ ½User mobility requires providing users with a uniform view of their preferred working environments ¿Ã‚ ½ user preferences and subscribed services ¿Ã‚ ½independent of their current positions in the network ¿Ã‚ ½.[1]  ¿Ã‚ ½Terminal mobility allows devices to transparently move and connect to different points of attachment ¿Ã‚ ½.[1]  ¿Ã‚ ½Mobile access is an emerging issue that involves th e dynamic adaptation of mobile-aware resources and services that mobile users and terminals can automatically retrieve regardless of their current location ¿Ã‚ ½.[1] Having considered the above types of mobility, mobile computing needs an advanced infrastructure which should dynamically trace and relocate mobile users and grant coordination between mobile entities. The infrastructure should also provide proper security level based on cryptographic mechanisms and tools. According to the given research paper three mobile computing services have been proposed: user virtual environment (UVE),mobile virtual terminal (MVT), and virtual resource management (VRM).  ¿Ã‚ ½UVE provides users with a uniform view of their working environments independent of current locations and specific terminals. MVT extends traditional terminal mobility by preserving the terminal execution state for restoration at new locations, including active processes and subscribed services. VRM permits mobile users and terminals to maintain access to resources and services by automatically requalifying the bindings and moving specific resources or services to permit load balancing and replication ¿Ã‚ ½.[1] SOMA-BASED MIDDLEWARE SOMA stands for Secure and Open Mobile Agent. SOMA is a service infrastructure for developing and implementing MA-based internet applications. SOMA consist of 4 layers. As shown in figure 1: Figure 1: http://www-lia.deis.unibo.it/Software/MA/Images/Mobile1.jpg The upper most layer is for mobility support which provides UVE (User Virtual Environment), MVT(Mobile Virtual Terminal), VRM(Virtual Resource Management). The next layer provides naming, security, migration, interoperability, persistence, communication and Quality of Service. The other two layers are a JVM (JAVA Virtual Machine) and a heterogeneous distributed system. SOMA is basically a JAVA based mobile agent which has been designed to provide the requirements of mobility, scalability, dynamicity, security and openness which are the typical issues in the internet scenarios. The two main goals to develop SOMA were interoperability and security. On one side, SOMA is based on detailed security model and provide a good range of mechanisms and tools to develop and enforce true security policies with flexibility. On the other side, SOMA is able to communicate and interact with different components of applications which are designed with different programming languages and platforms. Apart from interoperability and security features, SOMA is automatically and dynamically manageable and configurable and it provides the location abstraction to achieve scalability in a global scenario. The mobility of the mobile devices has introduced new security challenges like mobile can be hacked by the execution of malicious environment, may be cloned illegally to cause DoS (denial of service), or may be denial for roaming. These issues have been overcome in SOMA implementation as SOMA permits to protect both: agents come from malicious hosts and hosts from malicious agents. During the design and implementation of SOMA, number of challenges were faced to provide interoperability like SOMA application as server of COBRA, SOMA as COBRA clients, interoperability between COBRA components and SOMA, etc On the other hand, SOMA is a bit slow because of its extra security mechanisms, it involves different tools and techniques to provide more security which makes it slow as compare to other mobile agents but off course it is more secure than other mobile agents. As the name suggest secure and open mobile agent, its openness has introduced some more challenges to it especially for e-com merce applications so there is a need to improve it as nothing is perfect. Q2: All the MA(Mobile Agent) standards seem to be a promising platforms for implementing and developing applications in distributed, heterogeneous and open environments like the Internet. MAs try to overcome most of the limits of the conventional Client/Server model because of the basic features they have, such as autonomy and flexibility and can effortlessly integrate with the internet to extend accessibility of applications. Most of the application areas, like e-commerce, network management, mobile computing and information retrieval can benefit from the use of the mobile agent technology. There has been a lot of work done in this field. Like many mobile applications have been developed like we studies SOMA, there are some other application as well like SeMoA, Aglets, fraglets, etc. There are some advantages which all the mobile agents try to provide: Dynamic adaptation, flexibility, tolerance to network errors/faults, parallel processing, etc. Dynamic adaptation is the adaptation of t he different host environments. Tolerance to network faults means ability of mobile agent to operate without an active connection between server and client. Flexibility means to only source must be updated whilst changing an action of the agent. Comparing SOMA with other mobile agents, SOMA provides more security and openness as its name says. If we talk about SeMoA (Secure Mobile Agent) it has its own limitations, such as SeMoA is not very strong against a large number of Denial of Service (DoS) attacks like memory exhaustion. On the other hand SOMA has been designed taking into account security as a main property because SOMA protects both: agents come from malicious hosts and hosts from malicious agents. Another problem with SeMoA is that there are many classes in the core package that synchronize on the object of class itself. As local classes are shared and the visibility of local classes is global so any agent that access them and acquires a lock on such class objects blocks other threads to access them. On the other hand if we compare SOMA with fraglets which is very small computer program which has been designed to serve as a part of active network instead of a mobile agent. Fraglets have the ability to execute the codes on the path the travel by such as routers or hubs. Part 2: Q1:. Pervasive computing is a dream of personal computing where future living environments are saturated with non-intrusive, flawlessly operating services available for the user. To fully understand this dream these services are to adapt to the present situation of the environments, together with the economical/social situation of the user. Systems that use data about the state of either its system, users or the environment to settle in their behavior are called context-aware systems. Realizing context-awareness has introduced problems on different level: First, defining a context. Second, how and what can be adjusted when the context changes and where the context adaptation and definition comes from? Third, identify different contexts from sensor. Fourth, how a context can be represented and processed. But before that we have to understand the definition of context. The most cited definition of context by Dey is:  ¿Ã‚ ½Context is any information that can be used to characterize the sit uation of an entity. An entity is a person, place, or object that is considered relevant to the interaction between a user and an application, including the user and applications themselves ¿Ã‚ ½.[1] Representation: Unique Identifiers: The system should be able to recognize different type of contexts and environments in the real world. Uniqueness allow the reuse of that information without conflicting between identifiers. For example, If the user is driving a car so accelerometer can be used to detect the speed of the user. Validation: Validation should always be allowed for an information taken by the sensor before performing any action with it. For example, if the accelerometer indicates that the speed of user is fast (i.e. he/she is in the car) this does not mean that he/she is driving, this information should be validated before performing any action. For instance consider the condition that if I am driving I cannot answer the calls so reject the call and send a message saying I will call you later. But if I am in the car but I am not driving than I can answer the calls so the information from the accelerometer has to be validated before rejecting the calls. Uncertainty and incomplete information: As almost all of the context information of the real world is taken from the sensors, the information can be incomplete and uncertain. If we include reasoning uncertainty of the conclusions should follow the reasoning. Simplicity, reuse, and expandability: A system should supply only as expressive representation as necessary to maintain the domain knowledge. A simple representation endorse reuse and expandability. Simplicity, flexibility and expandability are among the requirements of context representation. Generality: Generality of context representation means the ability to support all types of context information. In my estimation, generality of a context representation is mostly described by its conceptual structure. Nevertheless, the clarity of a representation language which is used to generate the context information also vary its ability to generate context information at different levels of complexity. Q2. Introduction WAP (wireless application protocol) is a protocol to offer mobile data services. WAP is an open international standard that permits users to access global information instantly through any wireless device mobile phone, PDA, etc. WAP is normally supported by all operating systems. Browsers that uses WAP are called micro-browser. The rate of transfer of data is still very lower than the normal modem. On the other hand, I-mode is a complete mobile internet service that includes a large range of internet standards such as e-mail, sports results, weather forecast, news headlines, etc. This information is provided to the user by particular services from mobile carriers who charge them for these services. As the rate of transfer of the data is lower than the average modem, i-mode is not good enough for high resolution images and videos, it is basically sufficient for simple graphics and emails. Protocols WAP uses Wireless Markup Language (WML) for communication. while on the other hand i-Mode uses a different type of HTML which is called compact HTML (c-HTML). Capabilities of Devices WAP devices have to have a specific WAP browser while i-Mode supporting devices have to be able to display data from c-HTML. WAP capable devices show only textual information while i-Mode supporting devices shows multimedia images. WAP gives navigation among layered menus while i-Mode gives navigation via hyperlinks. Architecture WAP makes use of a unique language called WML (Wireless Markup Language) for interaction between a specific protocol translation device called a Gateway of WAP (GW) and information on the Internet. The GW communicates between HTML and WML, permits supply of WAP content to a WAP supporting device. iMode obeys a dissimilar approach to allow users to access IP-based services via their portable device. i-MODE is uses packet data transmission technology, a machine using this technology is continuously online. The transfer of the data makes use of the CDMA (Code Division Multiple Access). Graphics: One of the most main difference that appears, are clearly the dissimilar graphic capabilities. While it is right that i-MODE only allows simple graphics, that is much more than WAP. Charges: Another main dissimilarity is the capability of being always-on in i-MODE. As consumer are not charged for how long they serve online, it doesnt seem more suitable, but also less expensive than have to pay for the time they spent online. As it is not needed that dial-up before using the a variety of services based on IP, E-mail has become an SMS (Short Message Service). Part 3: Q1:. In CCA the InfoStations system is an infrastructural system concept offering many time, many-where access to wireless data services sustaining the portable communication process. This concept enables a variety of classes of portable devices to communicate with each other and with a large number of servers. Intelligent agents operating in the portable device users domain (Personal Assistants-PAs) and the InfoStations help to facilitate a contextualized and personalized environment for the system users. System functionality is offered as a set of flexible mobile services. To assist the personalization of these services, the User Agent Profile (UAProf) and Composite Capabilities/Preference Profile (CC/PP) terms are derived to enable the Personal Assistants express capability and preference information (CPI) about both the access device and the user as well. This makes sure that the offered services are adapted to suit the device capabilities, wireless network constraints and the user as well. Behavior of infoStation: Because of the fact that nature of the connection is defused, it is important for intelligent agents to work throughout the architecture. Being a PA (Personal Assistant), the agent may function automatically in order to convince any user service needs they encounter, while in or out of interaction with other agents which are working on InfoStation Centre or the InfoStation. The service sessions may be divided between different InfoStations, the personal assistant can make a service call while within the scope of an InfoStation, and then go out of the coverage area. During this time when the user goes out from InfoStation coverage, the personal assistant functions automatically adopt the functionality of the service till the user has completed the task. The InfoStations houses the Discovery, Presentation and Rendering Self-Service module, which is used to establish connections to mobile devices which enter within range. Also housed is a cache of recently accessed user and service prof iles, as well as a repository of available services.[4] Q2: Behavior of infoStation Centre: The InfoStation Centre stands at the centre of the system, which deals with the formation and updating of contents/objects throughout the system. From InfoStation Centre which acts as a central point, service updates can be spread across the whole system. All the infoStations are connected with the InfoStation centre which acts as a server of these infoStations. InfoStation centre is aware of all the devices connected to the infoStations but it communicates with infoStations only, it does not communicate directly to the devices connected to the infoStations. For instance a mobile device wants to communicate with the other mobile device connected with different InfoStation then the device will send a request to its InfoStation then the InfoStation send this request to InfoStation Centre and then InfoStation centre sends the request to the InfoStation to which the receiver device is connected with.

Wind Power in the United States Essay -- The Physics of Wind Turbines

I personally do not like windy days. However, wind could be helping us more than we realize. We could be using the wind to produce energy. This is what wind turbines do and now I will be researching them to determine the physics involved with them and how they work, their history, along with some statistics from the United States. Then I will go in-depth for the wind turbines of Texas, Washington, and Kansas and compare them. The Physics of Wind Turbines There is physics involved in these wind turbines as they change wind into mechanical energy and then into electricity. The energy produced depends on the volume of the air, the density, and the wind speed. The mass per unit time is the mass times the density times the wind speed or m = mass, p = density, A = area, and v = wind speed; m = pAV. Because the function of the wind turbine is to transform the wind’s kinetic energy into electricity the equation for kinetic energy is needed; KE =  ½ mv2 or kinetic energy equals one half the mass times the velocity squared. Then, using substitution, the power in the wind depends on the density of the air, area swept out by rotors, and the cube of the velocity or  ½ pAV3. Using Betz’ law the theoretical energy model for extracting 59% of the energy is power = 16/27( ½ pAV3) . The power passing through or created by the wind power is  ½ pAv3. All the power cannot be captured though, because that would mean the wind had to be still, absolutely no wind, which is impossible when the wind starts the whole process. Thus, one needs to find the maximum theoretical power output. To find the power, take the kinetic energy in through the wind turbine minus the kinetic energy out. Then using three different areas one can find the constant rate of ... ...issued on 2009 Aug 11, cited 2010 Oct 3]. [about 5 paragraphs].

Mobile Phone and Habits Modern Gadgets

Facilitating Communication †¢With devices like the cell phone, the BlackBerry and the laptop computer, people can communicate easily while on the go. Businesspeople can stay in touch with clients or the office while waiting for a plane or when in transit, which can increase their productivity. Parents can supply their children with cell phones so they can keep in touch with them when they're away from home. Texting allows individuals to exchange brief messages quickly without the need for face-to-face or telephone conversations. Shopping Habits Modern gadgets also influence how people conduct routine daily activities such as shopping. With the use of a computer with an Internet connection, consumers can easily compare products, gain a wide range of product information and conduct the entire shopping transaction without having to leave their homes or offices. According a 2009 Pew Research Center study, 80 percent of Americans age 33 to 44 indicated they purchased products online and 67 percent did their banking via the Internet. †¢Sponsored Lin †¢Health and Safety Issues oOn the downside, overuse of electronic gadgets can have an adverse effect on health and safety.According to the Med India website, a Carnegie Mellon University study indicated, extensive use of the Internet or playing video games can lead to social isolation and even depression. Stress levels can also increase, as mobile communication devices can make it more difficult for users to disconnect from work and find time to relax. According to the Washington Post, a 2010 National Safety Council Study indicated that 28 percent of traffic accidents in the United States occur due to people talking on cell phones or texting while behind the wheel. Inappropriate Behavior In some cases, modern gadgets and their associated technologies can facilitate inappropriate behavior. Online predators can use the relative anonymity provided by an Internet chat room to pose as a teenager and lure a teen into a potentially dangerous situation. Social media websites such as Facebook and Twitter can provide convenient avenues for â€Å"cyber bullying,† such as when teens use these vehicles to intimidate or humiliate other teens. Individuals may also use their cell phones to engage in threatening or harassing behavior via text messaging. Sponsored Links

Why Did A Stalemate Develop On The Western Front Essays

Why Did A Stalemate Develop On The Western Front Essays Why Did A Stalemate Develop On The Western Front Paper Why Did A Stalemate Develop On The Western Front Paper World war: How the Stalemate was developed In this piece of work I will be exploring the events between the start of the world war and Christmas 1914 and Ill be looking on how the stalemate developed. With the Schlieffen plan a wash at the onset of the war and the resulting race to the sea leaving the opposing sides on an unending series of trench-building marathons until they were lined up from the Alps in the south to the North Sea in the north. With the complete and almost idiotic reasoning of high command to send wool-clad men against well-protected, well-sighted, machine-guns, barbed wire and later armoured barbed-wire, heavy artillery, and long-range accurate rifle fire the life span of a soldier was measured in seconds during some battles. With the defence heavy technologies of the time coupled with lack of innovation and advancement by the offense side the battles that may last for months having huge losses and maybe yards are the only gains. Germany in Belgium Germany aim was to attack France and pull them out of the War because by doing this Germany think they would have won the war in a midst of a couple of months. Germany couldnt go straight through France because heavily allies defended the Franco-German borders. The Schlieiffen plan had to be put to work. Germany thought they will be able to march through Belgium and Luxembourg to quickly knock France out of the war; they have done it before they will do it again. They would think that Russia would take time mobilise; it was an all-or-nothing gamble. The main route through Belgium would be through the flat plains of Flanders; 34 divisions would be use to march through Belgium and 8 divisions would be used to hold back the German advance from the German borders. The main place that German was aiming for was Paris; if Paris was surrounded France would have been able to fight back but wouldnt have success. German knew that Russia could take up to 6 weeks to mobilise their army and Germany knew that they had 6 weeks to go through Belgium to get to France. The only problem with the Schlieffen was that Germany depended on the action of the other four countries (France, Russia, Britain and Russia). If the Schlieffen plan was not followed all hell would break lose. Germany marched into Belgium but Germany was not so lucky because Belgium gathered all there soldiers and try to stop the German advance. The Belgiums knew that Germany was twice their size but they put up a resistance from there frontier forts which was bombed by Germans. Belgium had hide themselves in underground tunnels were they waited for the German but the Germans had bomb these tunnels killing many Belgium soldiers. But this brought time for the British and French Army to mobilise. The Battle of Mons The British Expeditionary Force deployed in the fields of Belgium, led by Sir John French. The BEF moved into position in front of Mons creating a line along the Mons-Condi Canal, they were just to the left of the French fifth Army. The BEF dug in along the side of the Mons Canal awaiting the advancing Germans, who were marching through Belgium following the Schlieffen Plan. After the defeat earlier by the Germans General Charles Lanrezac, asked French to hold their position along the canal for 24 hours while French and the BEF fell back. On the 23rd August the BEF were attacked by the German first Army. The German Infantry were advance was repelled by the British Infantry, the sustained a very large losses; almost 1600 British Soldiers were killed and wounded. But with the French Plan 17 abandoned the French force retreated to defend Paris but found that Germany were in Paris they tried their hardest to push Germany back. British also had no other alternative but to retreat as well. If the French had hold their position along the canal they may have been able to push the German advance back and not lose so many soldiers, they may have been able to defeat German. But Germany may have brought more troops in from Germany. The Battle of Marne The French were on defensive in September 1914 but the German were not doing well either. The German Supreme Moltke had to pull out 100,000 troops from the army advance from Paris because they found out that Russia had mobilise quicker than supposed to and had already invaded Germany. This was proved that the British and French were needed. Another problem that had sprung up within the German force was that their advance had been so fast that their food and ammunition couldnt keep up. The German soldiers were unfed and really exhausted. The German commander, Von Kluck couldnt go round Paris as it was planned because the further they get away from their border line the less supply that would be about to get to them. So they decided to advance straight towards it. While the German Advanced on no other choice that foot, the French diverted troops to Paris by railway and then they were put on the front, some of them were transported by taxi. The Germany army couldnt hold it any longer they were weary and overstretched. British and French forces combined were able to stop the German army along the River Marne. The British and the French had counter attacked and pushed the Germans back to the river Aisne, but they couldnt drive them out of France entirely. The Race to the Sea The Battle of Marne was a turning point, for all 3 countries. The best known Plan (Schlieffen) had failed and Germany was caught up in a two-front war. The German general realised that they couldnt break through the enemy lines; Moltke was replaced by commander Falkenhayn who decided the best way to get to your enemy lines was to outflank them his enemy lines. The German were digging in to guard themselves from the advancing allies. The charge went on 12th October. This became the race to the sea. The Germans charged west towards to the sea. Each army tried to outflank the other to achieve the benefit, the British and French moved troops to block the Germans whenever it seems like they are about to attempted to break through. The First Battle of Ypres The battle of Ypres was in Belgium, this was one of the key battles in the race to the sea. Still trying to break through each others trench line, from the 12th October to 11th November 1914 the BEF lost around 50,000 men and the Germans lost around 100,000; but the British held the important ground-they kept the control of the English Channel Ports which meant they could be supplied with equipments and reinforcements. By November 1914 there was a deadlock, the BEF had been slaughtered. The French had already suffered around 1 million dead or wounded in just 10 weeks. Despite all this happenings, the French army tried to break through the German lines in Artois and Champagne in December but they were beaten badly back with heavy losses. As 1914 ends, the fighting had reach stalemate which was to last until 1918. Digging Trenches The reason of why trenches were built was to prove them cover from their enemy snipers and shell bombs. Trenches stretched from the sea (the English Channel) to the west of the Alps in Switzerland this was known has the Western Front. The trenches were dug at seven feet deep and six feet wide, they had to put it in a zigzag pattern to prevent the enemy from shooting in a straight line. The space between the opposing on the Western Front was between 100 and 300 yards apart. On the Eastern Front and Middle East the areas on the battlefield was too vast and the distance from the factory that sells shells, bullets, concrete and barbed wire was so great that the trench warfare in the European style was not eventuate. There were three standard ways to dig a trench: entrenching, sapping and tunnelling. Entrenching, where a man would stand on the surface and dig downwards, was most efficient as it allowed a digging party to dig the length of the trench simultaneously. However, entrenching left the diggers exposed above ground and hence could only be carried out when free of observation such as in a rear area or at night. Sapping involved extending the trench by digging away at the end face. The diggers were not exposed but only one or two men could work on the trench at a time. Tunnelling was like sapping except that a roof of soil was left in place while the trench line was established then removed when the trench was ready to be occupied. The guidelines for British trench construction stated that it would take 450 men 6 hours (at night) to complete 250 metres of a front line trench system. Thereafter the trench would require constant maintenance to prevent deterioration caused by weather or shelling. Types of Weapons The types of weapons used in 1914 were things like machine guns which could cause a lot of damage and kill soldiers in the open, they could fire up to 600 bullets a minute, machine guns were deemed to be a mass destruction. Artillery was the new and upgraded cannon they could fire up to 170 million shells in that time. But the Germans have different plans, the German Scientist have been planning the biggest artillery ever known, its name was Big Bertha it was so powerful it can fire at the heart of Paris from 120 kilometres away. The shells were also upgraded. Instead of the ordinary shells, they had high-explosive shells which were thin casing and full of tiny lead pellets. This was so effective that it killed hundreds and thousands of men; it also blew of the ground which made hiding more difficult for the soldiers. Gas Grenades were very effective weapon; they were highly toxic and could kill someone in a instant. There were 3 main gas grenades. The first was Chlorine gas which was used in the Battle of Ypres, the second Phosgene gas and the third was Mustard gas. This burned the lungs of the inhaler leaving them to die in agony. Gas masks were issued to everyone in the country, but they werent so useful and many people died. Transportation greatly increased, as more troops were needed at battlefields and other places. British forces used everything from trains to Lorries and even taxis. They transported 500 men in 1914; 250 taxis took the reserve troops to the Battle of Marne and thousands of lorries were used to transport troops to Verdun in 1916. Tanks were known as The Chariots of God at First, they were giant blocks of metal that could carry 1-2 personnel and travelled at about 5 kilometres per hour. But scientists and developers kept making new and improved tanks and by 1918 the Anglo-American Mark 8th could carry up to 8 men, and at the same time fire 208 shells and up to 13,000 bullets. Although these beasts were powerful, they were not so reliable. Most broke down and a good example is the battle of Amiens. The British sent 525 tanks, and after four days, only 25 were left in working order. Rolls Royce also joined in the development of these tanks, by building their own armoured car! It could travel up to 88 kilometres and had 8mm machine guns. Planes were the new types of weapons use in advanced technological warfare. They had everything from mini scout planes to huge blimp like bombers called Zeppelins. Air warfare was not seen as important as any other type so it did not have its own category. Conclusion I think Germany invading Belgium is the most responsible for the stalemate, because if German hadnt invaded Belgium they wouldnt have gone through a series of Battles. German trust a plan that was made quite sometime ago which relied of the actions on the other countries around them which may have been different like it was. But if Belgium just let Germany thorough there country then Germany could have captured Paris quickly enough and kicked them out of the war and the war may have been finished by Christmas. But one different move may have changed the whole history of this from a 4 year war to a 5 months war. I think because of the actions of both Germany and Belgium the war was at stalemate. Belgium was a neutralised country they werent on any side so there wouldnt have been a problem with German forces marching through their country?

Benchmarking Logistics Performance

Benchmarking Logistics Performance Abstract Benchmarking, being a decision-making technique, can go a long way in making an organization gain competitive advantage over competitors. This is significant because benchmarking ensures sharing of information in an organization by simplifying operations and performance. Benchmarking can help an organization become efficient through various methods. However, the whole process does come with its challenges.Advertising We will write a custom essay sample on Benchmarking Logistics Performance specifically for you for only $16.05 $11/page Learn More Two stage Benchmarking Methodology A two-stage benchmarking method is beneficial for an organization. This technique uses performance evaluation metrics followed by continuous improvement metrics in aiding an organization achieve the needed competitive advantage. In performance evaluation, the performance of the benchmarked company provides a standard  for evaluation with other competitors. For example, Ca pstone Logistics may look at how to incorporate proper technology to manage its needs and make the best choice for its transportation needs. Thus, this will confirm what the competitors do to select the best choices to achieve the goals, and if possible be dominant (Murray, 2010). All the parameters in performance evaluation have to be factored. For instance, issues like partnerships, analysis of buyers or suppliers and even relationships of the organization are issues that are thoroughly considered. Partnership evaluations help in cementing supply chain systems thus facilitating organization’s strategic goals. The partnership evaluation parameter can be noted in the level of support involving major organizational issues. This parameter can aid in identifying and solving complex problems. Another aspect of performance is delivery performance analysis. Here, the lead-time is critical as the time the deliverables reach their respective target is assessed. In this case, on-time delivery will inevitably suggest that ideal distribution has been achieved. Delivery also has another feature that borders on the capacity of what has been on transit. Capstone Logistics therefore considers alternatives that influence supply chain such as speed of vessels, dependability of driver and location depots. This analysis increases efficiency leading to a decrease in portfolio levels (Novich, 1990). Continuous improvement can also boost a firm’s principal value. It is therefore expected the supply chain management continually improves on efficiency. However, Lee and Billington (1992) recognize that benchmarking logistics staging cannot complete adeptness if different facets of the supply chain track objectives autonomously. Continuous improvement also complements the performance evaluation metrics since it also takes in the other arising issues. It considers the grey areas that are arising.Advertising Looking for essay on business economics? Let's see if we can help you!

This new technology, when incorporated, increases effectiveness and efficiency in an organization (Murray, 2010). For example, improved data mining could do well towards all the company roles. Capstone Logistics for example, has a system that allows users to access the system and validate the model. Though benchmarking may contribute to the body of knowledge, it is essential for an organization to understand why clients are attached to it. For example, DHL does recognize that its customer loyalty arises out of efficiency and effectiveness of its operational process. Analytical method thus serves to give an order of fixing what to benchmark. An analytical analysis helps to assess issues such as process selection, clustering of the different customer wants and may include value chain for benchmarking. AHP was initially quite helpful in measuring the service quality of many organizations. However, the analytical method has failed in measuring the quality of a single organization. It is worth noting that organizations face different dynamics. Thus, it is wise to ensure that valuable quality of service of a single organization is established to assist in measuring customer satisfaction and other parameters, which are difficult to quantify. For example, AHP attempts to address judgmental and psychological information that may be difficult to quantify. An organization should take up a process improvement initiative with the zeal to achieve results (Murray, 2010). Many organizations take up initiatives with the opinion that only the customer benefits and thus fail to reap the fruits of a whole process improvement initiative. Quality improvement aims at benefitting both the client and the organization. An effective model is also that which incorporates the staff. AHP can be a model used for evaluation a nd comparison but also used to increase the benefit. It is a better model if it incorporates staff so action plans expected can encourage competitiveness. That is, complete satisfaction and participation of the team ensures success of the model (Murray, 2010). 3PL plays an essential role in successful benchmarking approach. Capstone Logistics has implemented 3PL solutions that produce several key roles.Advertising We will write a custom essay sample on Benchmarking Logistics Performance specifically for you for only $16.05 $11/page Learn More This has helped improve the process, reduce operational costs as well as aid in implementation of sustainable best practices. It has also helped in time optimization besides providing a platform through which the management system can draw information to aid in decision-making. Capstone Logistics uses the 3PL technique to provide transportation intelligence, track shipments and manage carriers among others. Conclusion Benchmarking logistics performance is critical to achieving an organization’s success. This is because it goes deep into critically analyzing all the organization’s value drivers thereby achieving the general success of that organization. Reference List Lee, H. L., and Billington, C.

Safety managment - Coursework Example According to OSHA, injury and illness rates stood at 22.2 while lost workday injury and illness (LWDII) at 8.1. Currently, the company projects a 17.6 and 7.8 from the previous year with a BLS of 12.5 and 6.6 respectively (SIC 3069). Certainly, this is a worrying trend forming the core intention of the paper to provide an action plan for the management of safety and health objectives. Four critical questions guide safety and health programs within any organization. For instance, is the return on investment satisfactory? How can we include safety and health programs in the business? What indicators reveal strength or weakness? And most importantly, the practices with a lasting success within an organization. Answers to these questions are potential guide to success. It collaborates with different government agencies to manufacture composite materials for the US defence department for unclassified purposes. Nevertheless, the promising future is tantamount to many problems considering the many risks and injuries facing the company. Obviously, the current state of XYZ categorises it as a health risk. Coincidentally, workers have the right to safe working conditions and OSHA laws prohibit employers against denying them such rights. Voluntary protection programs (VPP) is an OSHA cooperation program that recognize workers in the private industry and federal agencies. VPP ensures workplaces go through rigorous analysis, encourage training and union representation to keep injury and labour relations at controllable rates. Organizations competing for products and services tend not to focus on safety practices; however, not known to many these costs greatly affect the overall performance (Maguire 46). In fact, safety as a nagging problem that keeps people from the main business. Many industries have safety programs, but few have working ones; therefore, is important to not only form a program but also ensure it works. A safety management plan defines the oversight

The Fetish of the Size 0 Woman Dissertation Example | Topics and Well Written Essays - 2500 words

The Fetish of the Size 0 Woman - Dissertation Example In recent years, one of the more popular forms of television entertainment has been the concept of the makeover show. These shows are focused primarily on re-forming women’s bodies into something that more closely matches the societal perception of the ideal regardless of the woman’s other natural abilities, talents or attributes. This ‘ideal’ image is usually defined as someone of a mid-20ish age, slender, with specific measurements and a certain good-looking charm. This limited view of the ideal automatically eliminates anyone who might have been born with a larger bone structure or other ‘defect’ that defies the reshaping of the scalpel from the ranks of the socially acceptable. Through the reality shows, though, those lucky few who are able to fit the ideal in any way, to attain the ‘body beautiful’, much is made of their subsequent happiness and success as a result of their ‘improved’ appearance and slenderer selv es. ASPS president Rod Rohrich pointed to the various individuals taking part in plastic surgery reality television indicating that many of them have unrealistic and unhealthy expectations for the results

FINAL DAIVS - Essay Example The deployment of intelligence officers as undercover agents may yield valuable information. The investigations are supposed to be carried out in North Korea shipping terminals, and airports. Though it is a dangerous undertaking, South Korean intelligence can be used. This is because the Koreans have similar culture and language thus detection would not be easy. In addition to human intelligence, signal intelligence can be useful this entails detection of signals of communication between North Korea and Iran. This would enable the agents to know the shipping lines, date and time. As such interception can be easy. Signal interceptors can be schemed to tap signals emanating from North Korea key leaders and also Iran leaders, especially the military leaders. To make sure that the technology is not transported by land, the agency is supposed to alert the various governments involved along the transport corridor to Iran. By doing this, the threat of land transport could be minimized. Agents working on the ground should also have a backup plan in case the plan fails. There should be reinforcement in case their cover is blown. An effective backup may be the US Navy which can extract the persons from danger. Moreover, the navy can also be instrumental in sea interceptions. 2. You lead an analysis team for Army Intelligence. Your team has been assigned the task of determining what conditions will be like in Afghanistan after we draw down our troops, and also to determine if the Strategic Partnership agreement President Obama just signed will hold. Describe what your analysis will cover and what key questions your team needs to answer. What assistance will you need and from what other members of the IC? Afghanistan is a highly tribal country with armed groups read to destabilize the country. Since the ouster of the Taliban, the US troops, alongside NATO has been instrumental in maintaining peace. Afghanistan has a democratically elected government; however, it is

Auditing Practices, Professionalism, Ethics, And Standards Essay

Auditing Practices, Professionalism, Ethics, And Standards - Essay Example Auditor independence refers to the internal auditor’s independence and freedom from freedom from any form of control by parties that may have financial interests in the business under auditing (Baker, 2005, p.13). The independence of auditors particularly demands a considerable level of professional integrity, ethics and objective approach to the entire auditing process without any external influence. According to many experts, auditor independence may also be used in reference to the external auditors' exclusion from parties that may have financial interests in the businesses being audited. Generally, achieving independence is critically essential for the auditors to be able to effectively retain their objectivity and service reliability.According to Sikka (2008, p.271), the current auditing practice of making auditors depend on their directors for their fees, remunerations, and profits has been widely blamed for the rising cases of corruptions, manipulations and integrity is sues among auditors. Although it has been argued that auditors still redeem their status by appealing to and incorporating professionalism in their practice, this is not always possible as auditors just like other capitalist enterprises are often driven by personal interests particularly the need to increase their profits and market niches.The contemporary Australian Audit ethical standards particularly require an integrity and objective approach to the audit process (Australia, 2011 p. 123).

Assignment about ethics Example | Topics and Well Written Essays - 1000 words

About ethics - Assignment Example System 1 thinking is characterized by an unconscious and automatic way of thinking. This system has the universal cognition that occurs both in human beings and in animals, an aspect that is considered evolutionary. System one thinking is comprised of subsystems that work hand-in-hand within the same autonomy. System 1 thinking is responsible for instinctive behaviors that are programmed inherently. This system solves problems through the dependence of prior information that is associated with the system including automatic, holistic and fast cognitive ability (Kaufman & Singer, 2012). System 2 is recent compared to system 1. This system is characteristic of human beings only. This system is also understood as the explicit and rule-based system. It is slow, sequential, and domain-general and is performed in the central memory system. System 2 allows abstract hypothetical thinking that does not happen in system 1. This system functions with regard to logical standards and is rule based, demanding, analytic and controlled of cognitive capacity (Kaufman & Singer, 2012). The kind of individual ethical problem-solving that happens in business and organizations involves the application of system 1 and system 2 thinking. The use of instinctive information must be used then making an ethical decision. It also involves a holistic approach that will involve looking at the causes of the ethical problem and going towards the identification of a solution. System 2 is also significant because ethical problem solving in a business or an organization must be made using logic and reasoning. This happens in the sense that one has to think through an ethical dilemma or problem and go through certain processes that involve identification, ranking, developing an action plan, implementing it and reflecting on its success. An example of a system 1 response to an ethical dilemma in business is when

Devil Facial Tumor Disease Essay Example | Topics and Well Written Essays - 1000 words

Devil Facial Tumor Disease - Essay Example As the report declares the DFTD is considered to have commenced in the Mount William National Park’s far north eastern region, from a prospect mutation. During 1996, Tasmanian devils with prominent facial tumors were snapped in the north-eastern Tasmania. After ten years, these features are found to be coherent with DFTD. This discussion declares that the cancer, DFTD, is found to be transmitted from one animal to another through biting either during fighting, eating or mating. It develops quickly, congesting the mouth of animal and then disseminates to other organs. The illness has consumed sixty percent of entire Tasmanian devils population since it was initially detected in 1996, and it has been predicted by some ecologists that it could efface the complete wild population till 2035. DFTD seems to be a cloned cell line, that is transmitted in the form of an allograft from one devil to another and this transmission may be found similar to that in CTVT and a communicable sarcoma infecting Syrian hamsters. The biology and prevalence of such vegetative cell parasites is typically unknown. The examinations of captivated Tasmanian devils suggest that this species has a tendency to develop tumors, specifically carcinomas. Nevertheless, DFTD is found to be significantly different from previously reported d evil cancers, and to determine its etiology is vital for the development of strategies to manage the disease.

Generally, achieving independence is critically essential for the auditors to be able to effectively retain their objectivity and service reliability.According to Sikka (2008, p.271), the current auditing practice of making auditors depend on their directors for their fees, remunerations, and profits has been widely blamed for the rising cases of corruptions, manipulations and integrity is sues among auditors. Although it has been argued that auditors still redeem their status by appealing to and incorporating professionalism in their practice, this is not always possible as auditors just like other capitalist enterprises are often driven by personal interests particularly the need to increase their profits and market niches.The contemporary Australian Audit ethical standards particularly require an integrity and objective approach to the audit process (Australia, 2011 p. 123).

Devil Facial Tumor Disease Essay Example | Topics and Well Written Essays - 1000 words

Devil Facial Tumor Disease - Essay Example As the report declares the DFTD is considered to have commenced in the Mount William National Park’s far north eastern region, from a prospect mutation. During 1996, Tasmanian devils with prominent facial tumors were snapped in the north-eastern Tasmania. After ten years, these features are found to be coherent with DFTD. This discussion declares that the cancer, DFTD, is found to be transmitted from one animal to another through biting either during fighting, eating or mating. It develops quickly, congesting the mouth of animal and then disseminates to other organs. The illness has consumed sixty percent of entire Tasmanian devils population since it was initially detected in 1996, and it has been predicted by some ecologists that it could efface the complete wild population till 2035. DFTD seems to be a cloned cell line, that is transmitted in the form of an allograft from one devil to another and this transmission may be found similar to that in CTVT and a communicable sarcoma infecting Syrian hamsters. The biology and prevalence of such vegetative cell parasites is typically unknown. The examinations of captivated Tasmanian devils suggest that this species has a tendency to develop tumors, specifically carcinomas. Nevertheless, DFTD is found to be significantly different from previously reported d evil cancers, and to determine its etiology is vital for the development of strategies to manage the disease.

Various Types Of Robots Computer Science Essay

Various Types Of Robots Computer Science Essay A Robot is man-made mechanical device that can move itself, whose motion must be modeled, planned, sensed, actuated and controlled, and whose motion behaviour can be influenced by programming. Robots are called intelligent if they succeed in moving in safe interaction with an unstructured environment, while autonomously achieving their specified tasks. This definition implies that a device can only be called a robot if it contains a movable mechanism, influenced by sensing, planning, actuation, and control components. It does not imply that a minimum number of these components must be implemented in software, or be changeable by the consumer who uses the device; for example, the motion behaviour can have been hard-wired into the device by the manufacturer. 12.2 Three Laws of Robotics Science-fiction author Isaac Asimov is often given credit for being the first person to use the term robotics in a short story composed in the 1940s. He suggested three principles to guide the behavior of robots and smart machines.- A robot may not injure a human being or, through inaction, allow a human being to come to harm. A robot must obey orders given it by human beings except where such orders would conflict with the First Law. A robot must protect its own existence as long as such protection does not conflict with the First or Second Law. 12.3 Components of robotic systems This figure depicts the components that are part of all robotic systems. The real robot is some mechanical device (mechanism) that moves around in the environment, and, in doing so, physically interacts with this environment. This interaction involves the exchange of physical energy, in some form or another. Robotics as an integrated system of control interacting with the Figure : components of robotic system Both the robot mechanism and the environment can be the cause of the physical interaction through Actuation, or experience the effect of the interaction, which can be measured through Sensing. Sensing and actuation are the physical ports through which the Controller of the robot determines the interaction of its mechanical body with the physical world. As mentioned already before, the controller can, in one extreme, consist of software only, but in the other extreme everything can also be implemented in hardware. Within the Controller component, several sub-activities are often identified: Modelling- The input-output relationships of all control components can (but need not) be derived from information that is stored in a model. This model can have many forms: analytical formulas, empirical look-up tables, fuzzy rules, neural networks, etc. The other components discussed below can all have models inside. A System model can be used to tie multiple components together, but it is clear that not all robots use a System model. The Sensing model and Actuation model contain the information with which to transform raw physical data into task-dependent information for the controller, and vice versa. Planning- This is the activity that predicts the outcome of potential actions, and selects the best one. Almost by definition, planning can only be done on the basis of some sort of model. Regulation- This component processes the outputs of the sensing and planning components, to generate an actuation setpoint. Again, this regulation activity could or could not rely on some sort of (system) model. The term control is often used instead of regulation, but it is impossible to clearly identify the domains that use one term or the other. 12.4 Parts Concept required for Robot Generally robots have at least the below mentioned parts and concepts: Sensors Most robots of today are nearly deaf and blind.   Sensors can provide some limited feedback to the robot so it can do its job.   Compared to the senses and abilities of even the simplest living things, robots have a very long way to go.  The sensor sends information, in the form of electronic signals back to the controller.   A sensor also gives the robot controller information about its surroundings and lets it know the exact position of the arm, or the state of the world around it.  Sight, sound, touch, taste, and smell are the kinds of information we get from our world.   Robots can be designed and programmed to get specific information that is beyond what our 5 senses can tell us. For instance, a robot sensor might see in the dark, detect tiny amounts of invisible radiation or measure movement that is too small or fast for the human eye to see Switch Sensors Light Sensors Polarized light Resistive Position Sensors Effectors An  effector  is any device that affects the environment. Robots control their effectors, which are also known as end effectors. Effectors include legs, wheels, arms, fingers, wings and fins. Controllers cause the effectors to produce desired effects on the environment. Two basic ways of using effectors: to move the robot around =>locomotion to move other object around =>manipulation Actuators Actuators, also known as drives,  are mechanisms for getting robots to move. Most actuators are powered by pneumatics (air pressure), hydraulics (fluid pressure), or motors (electric current).  Most actuation uses electromagnetic motors and gears but there have been frequent uses of other forms of actuation including muscle-wires and inexpensive Radio Control servos. To get a motor under computer control, different motor types and actuator types are used. Some of the motor types are Synchronous, Stepper, AC servo, Brushless DC servo, and Brushed DC servo.   Radio Control servos for model airplanes, cars and other vehicles are light, rugged, cheap and fairly easy to interface. Some of the units can provide very high torque speed. A Radio Control servo can be controlled from a parallel port. Controllers The robot connects to a computer, which keeps the pieces of the arm working together. This computer is the controller. The controller functions as the brain of the robot. The controller can also network to other systems, so that the robot may work together with other machines, processes, or robots Arms common effectors known as Arms. The robot arm comes in all shapes and sizes and is the single most important part in robotic architecture. The arm is the part of the robot that positions the End Effector and Sensors to do their pre-programmed business. Many (but not all) resemble human arms, and have shoulders, elbows, wrists, even fingers. This gives the robot a lot of ways to position itself in its environment.   Artificial Intelligence The term artificial intelligence is defined as systems that combine sophisticated hardware and software with elaborate databases and knowledge-based processing models to demonstrate characteristics of effective human decision making. The criteria for artificial systems include the following: functional: the system must be capable of performing the function for which it has been designed; able to manufacture: the system must be capable of being manufactured by existing manufacturing processes; designable: the design of the system must be imaginable by designers working in their cultural context marketable: the system must be perceived to serve some purpose well enough, Mobility Industrial robots are rarely mobile. Work is generally brought to the robot. A few industrial robots are mounted on tracks and are mobile within their workstation. Service robots are virtually the only kind of robots that travel autonomously. Research on robot mobility is extensive. The goal of the research is usually to have the robot navigate in unstructured environments while encountering unforeseen obstacles. Some projects raise the technical barriers by insisting that the locomotion involve walking, either on two appendages, like humans, or on many, like insects. Most projects, however, use wheels or tractor mechanisms. Many kinds of effectors and actuators can be used to move a robot around. Some categories are: legs (for walking/crawling/climbing/jumping/hopping) wheels (for rolling) arms (for swinging/crawling/climbing) flippers (for swimming) Types of robot 12.5.1 Mobile Robot- Mobile robots are able to move, usually they perform task such as search areas. A prime example is the Mars Explorer, specifically designed to roam the mars surface. Mobile robots are a great help to such collapsed building for survivors Mobile robots are used for task where people cannot go.   Mobile robots can be divided in two categories   1.1 Rolling Robots:   Rolling robots have wheels to move around.   These are the type of robots that can quickly and easily search move around.   However they are only useful in flat areas, rocky terrains give them a hard time.   Flat terrains are their territory 1.2 Walking Robots:   Robots on legs are usually brought in when the terrain is rocky and difficult to enter with wheels.   Robots have a hard time shifting balance and keep them from tumbling.   Thats why most robots with have at least 4 of them, usually they have 6 legs or more.   Even when they lift one or more legs they still keep their balance.   Development of legged robots is often modeled after insects or crawfish. Stationary Robots Robots are not only used to explore areas or imitate a human being.   Most robots perform repeating tasks without ever moving an inch.   Most robots are working in industry settings.   Especially dull and repeating tasks are suitable for robots.   A robot never grows tired; it will perform its duty day and night without ever complaining.   In case the tasks at hand are done, the robots will be reprogrammed to perform other tasks Autonomous Robots Autonomous robots are self supporting or in other words self contained.   In a way they rely on their own brains. Autonomous robots run a program that gives them the opportunity to decide on the action to perform depending on their surroundings.   At times these robots even learn new behavior.   They start out with a short routine and adapt this routine to be more successful at the task they perform.   The most successful routine will be repeated as such their behavior is shaped.   Autonomous robots can learn to walk or avoid obstacles they find in their way.   Think about a six legged robot, at first the legs move ad random, after a little while the robot adjust its program and performs a pattern which enables it to move in a direction Remote-control Robots An autonomous robot is despite its autonomous not a very clever or intelligent unit.   The memory and brain capacity is usually limited; an autonomous robot can be compared to an insect in that respect. In case a robot needs to perform more complicated yet undetermined tasks an autonomous robot is not the right choice.   Ã‚  Ã‚   Complicated tasks are still best performed by human beings with real brainpower.   A person can guide a robot by remote control.   A person can perform difficult and usually dangerous tasks without being at the spot where the tasks are performed.   To detonate a bomb it is safer to send the robot to the danger area Virtual Robots   Ã‚   Virtual robots dont exist in real life.   Virtual robots are just programs, building blocks of software inside a computer.   A virtual robot can simulate a real robot or just perform a repeating task.   A special kind of robot is a robot that searches the World Wide Web.   The internet has countless robots crawling from site to site. These WebCrawlers collect information on websites and send this information to the search engines.    BEAM Robots BEAM is short for Biology, Electronics, Aesthetics and Mechanics.   BEAM robots are made by hobbyists. BEAM robots can be simple and very suitable for starters. Key Points Robotics  is a branch of engineering that involves the conception, design, manufacture, and operation of  robots. Field of robotics overlaps with electronics, computer science,  artificial intelligence  , mechatronics,  nanotechnology  , and bioengineering.

Legalizing Marijuana Essay -- social issues

Legalizing Marijuana The purpose of this paper is to discuss marijuana and compare both sides of the issue of legalizing marijuana. We have two factions fighting each other; one those who are pro marijuana and those who are anti marijuana. These two factions have been fighting on this issue on the halls of justice for years. Pro marijuana legalization groups such as the Physician's Association for AIDS Care, National Lymphoma Foundation argue that marijuana should be legalized in order to treat terminally ill patients. Among them are AIDS victims who find that marijuana stimulates their appetites so they can fight off dangerous emaciation; glaucoma sufferers who have used marijuana said it has prevented them from going blind, and cancer patients for whom it alleviates the severe nausea that is often accompanies chemotherapy and sometimes makes lifesaving treatment impossible. Due to all these lobbying groups which show substantial evidence that marijuana can be used as a prescribed drug. Also many advocates who are pro marijuana complain that morphine and cocaine are legal and are very dangerous drugs, that brings up the question why not legalize marijuana as medical drug which is proven to be less dangerous than cocaine and morphine. Lobbying groups in a San Diego, California , council committee unanimously voted to urge president Bill Clinton and congress to end federal restrictions against the use of marijuana for " legitiment medical use."

Is the Job in Fast-Food Restaurant Exploitative Essay

Exploitation is a term to describe person that are being mistreated. Karl Marx used it to explain the relationship between the capitalists and workers. It is claim that the value of a product is depended by how much labor has paid on it such as time, energy or ideas. Therefore the price of a product minus the cost and energy to produce a product or other sufficient usages should be equal to what a worker can earn. However, as the workers own nothing but their labor, they could only sell their labor to capitalists who own all other kinds of resources. Marx defined the value that capitalists take away from the workers as surplus value. It should be fair between â€Å"sellers† and â€Å"buyers†, but the capitalists refuse to pay a suitable amount of reward. In order to gain more profit, the capitalists would try as hard as they can to increase the surplus value, and lead to exploitation. In the paragraph below, I will first start with reason why Hong Kong fast food workers being exploited. Second I will focus on the current situation of exploitations in Hong Kong fast food restaurant. In addition, I will express my opinion on the implantation of minimum wage. It could only improve the situation of workers but could not solve the problem of exploitation. Reason for being exploited Workers in fast food shop is being exploited mainly because of the supply of workers is far more than the demand of job opportunities. In general, the jobs in fast food restaurant are independent to the education level. It is because most of the job opportunities in fast food restaurants are being simplified and divided clearly. With the aid of machines, almost everyone could do the job well; no specific skills are needed in fast food restaurants. Therefore this kind of jobs will depend much more on social skills such as communicate with customers, meaning that this kind of jobs is widely open to different types of people. In 2007, there are approximately 32,100 fast food restaurant employee, compare with unemployment workers of age group between 20 to 50, which is over 100,000 in 2007. It is obvious that the supply of potential workers is far more than the job opportunities. Since the workers lack of bargaining power, it means capitalists could heavily exploit and extract the surplus value from workers. In order to earn a living or at least subsidies the family, workers have no choice but to accept the offer from capitalists. Exploitation in Hong Kong fast food restaurant There are two sectors for capitalists to exploit the labors, first is low wage and long working hour , another would be on cutting employee welfare, and these two kinds of exploitations are common in fast food restaurant. It is terrified that the first aspect, low wage and long working hour, is a kind of norm in fast food industry. In before minimum wage launched, the average wage of fast food restaurant workers is extremely low, most of the fast food restaurant offer the workers with less than $20 per hour. Besides pay for a low wage to workers, long working hour and mechanized steps in the fast food industry also reflect exploitation on the workers. As the capitalists treat labor as a product, they want to use this product to gain profit as much and fast as it can. On one hand they reduce the wage of workers, on the other hand the want to increase the rate of getting reward. They therefore encourage their workers to work overtime. Since the wages are too low that workers can not even earn a living for their family, they must need to work longer to fulfill the needs. The research conducted by HKCTU in 2006 showed that the maximum working hour for fast food shop workers may up to 10 hours per day, but still they not earn enough for their family. Overtime working had already been proved that would lead to greater chance of getting heart attack. Capitalists sacrifice the lives of their workers to gain profits, which is created by workers. Exploitation can also be found on welfare. If there is a contract relationship between employer and employee, both of them should be protected by laws. However, the laws in Hong Kong show that it is unbalance. The laws protect the employer more than that of employee and it also leads to exploitation. There are some cases that the capitalists avoid to pay for the employee welfare that a workers should have by using loopholes in the laws. The current labor laws stated that for all employees that continuously working for 4 weeks and each of the weeks working for not less than 18 hours, he or she will be protected by the law and can enjoy the employee welfare. However, this law comes with a lot of loopholes that let the capitalists have room to avoid paying employee welfare, like force the workers stop working every 3 weeks. It becomes a characteristic in fast food industry because of its unbalance between supply and demand. The working hours of this kind of â€Å"short-term† workers may equal to long-term workers, but the worker will never receive the benefits form the welfare. This make the whole thing legal and the exploitation may continue. Some extreme cases even show that capitalists may act illegally to exploit the employee welfare. In 2009, the motorbike couriers from McDonald were discovered that they had forced to be self-employ, meaning that they do not have any paid holiday, insurance or any other employee welfare. It is rather on the edge but since the current labor laws is not strict enough to protect the employee and rather or not the company is abusing the self-employ scheme is hard to be proved, the problem still remain unsolvable. Implantation of minimum wage The minimum wage law could reduce the level of exploitation, but capitalists could develop new methods to exploit the workers. According the findings of HKCTU, the wage of fast food restaurant workers after the launched of minimum wage has been increased for 20% to 50%. It is also glad that some of the fast food restaurants such as Cafe de Coral and Fairwood paid for the dinning hours and provide paid holidays to their workers which are previously do not. They are good news for the workers, but when comparing to the current situation, it could only solve part of the problem of low wage, but the law still not protecting the welfare of workers, current labor laws still rely on â€Å"4-18 scheme†. In addition, in order to maintain the profits to balance the increase in wage, some of the fast food restaurants implant new machines to their fast food restaurants. It increases the rate of trading, meanings the rate of getting reward increase. Although the capitalists claim that the new machines will not cause any dismiss of workers, new machines further simplified the process in fast food restaurants. Lower the skills level for fast food restaurant jobs indicate that the bargaining power of workers will not increase but further slide down. The set up of minimum wage provide an index for capitalists to exploit. Now they can not reduce the wage of workers, but instead they exploit the workers with brand new ways. The form of exploitation has been change but does not mean that exploitation has disappeared. Conclusion In Hong Kong, the supply of labor is far more than the demand, causes the powerless situation of workers. In order to earn for their families, they could only be exploited. Minimum wage improves the current situation of labor, but could not solve the problem. The only way that balance the relationship between capitalist and workers, may rely on create new laws. If we need to solve the problem, the implant of minimum wage is the first step only.
