Political Science questions - Essay Example These reflected into two that is extreme realism and moderate realism that all provide a different opinion on realism. Extreme realists William of Champeaux related realism as a position in which the universals exist through an independence of the humans and other particular things related in the field. On the contrary, other philosophers viewed this realism as so extreme and considered realism in the eyes of God as the relation through which particular things are created. This moderate theory as proposed by St. Thomas Aquinas and John of Salisbury. In relation to political realism, international relations come to consideration. These relate to general theories of political realities of the world. The aspect of political realism on this international perspective reflects aspects of competiveness within international communities and conflicting aspects that relate to the ultimate security aspects. Idealism and liberalism are part of this realism parameters. Idealism and liberalism deal more with the emphasizing of cooperation’s on an international level. It is therefore fair to conclude the position of the world based on realist as a connection of different states with regard to competition that has raised conflicts through which security has soured.

How can human resources (people) working in the bureaucratic Essay

How can human resources (people) working in the bureaucratic Intelligence Agencies affect the outcome of interagency collaboration efforts - Essay Example olicymakers are all in a mad scramble about addressing the problem of intelligence failure that made the 9/11 terrorist attack by the Al Qaeda successful. Emerging policies concerning the intelligence community demonstrate a preference for a closer interagency collaboration as this was the factor widely blamed for the 9/11 attacks. However, the sixteen agencies and departments that comprises the American intelligence community will undoubtedly find it difficult to make the transition from an existing way of doing agency business to a new and more collaborative way because it require the human resource to withdraw even temporarily from bureaucratic philosophy. Here, agencies must spurn something that they have least respected and cherished. In addition, an agency must be willing to discard its culture if necessary, or, if possible, break it up into components, some of which might warrant being salvaged and recycled. This is the reason why human resource is pivotal in achieving interagency collaboration. This paper will address how human resources working in the bureaucratic Intelligence Agencies affect the outcome of interagency collaboration efforts. Specifically, this paper will discuss why each individual human resources, available to Intelligence Community Agencies, have more a more significant and influential role towards increasing interagency collaboration and integration than the technological advances and high budget resources they work with. Presently, there is an excessive dependence on high-tech intelligence in the United States military establishment, including a tight integration between the technical intelligence and conventional military intelligence and that it could be problematic as demonstrated by the fighting in Iraq. (Posner, p. 70) There are several studies that show why human resource is significant in interagency cooperation in the intelligence community – a role that is even more significant than technological advances and budget

Into the Cold War - Assignment Example In addition, he suggested that the United State show a non-proactive resistance that could even lead to the breakdown of the Soviet Union (Miscamble and George 39). In other places in the United States where had started to spread, the Truman doctrine was adapted. Truman requested for help from Turkey and Greece and promised to contain the spread of communism in Europe via the assistance of any country with the economic and the military help in case their stability received any threats firm the Soviet Union. The Truman doctrine is the ground of the president’s foreign policy. Truman argued that the cold war was a selection between oppression and freedom and that the people of the united states were forced to support the free individuals and leave their own choice and decision to avoid getting involved in the European issues . It is thus clear that the Truman Doctrine was not just a strategy of containment but also an American challenge to the ambitions of the Soviet Union (Miscamble and George

Establishment of Hong Kong as a British Colony Essay

Establishment of Hong Kong as a British Colony - Essay Example The periodical Hong Kong: Colonial Legacy, Transformation and Challenge takes a step by step approach to justify its conclusion. Ming K Chan shows his capability as an excellent observer of general feelings as well as of future trends. Ming K Chan is not too kind on British as he explains the much-publicized laissez-faire colonialism was far from fair. The influence of British establishments was a selective alliance of the colonial bureaucracy and industrialist entrepreneurship. There was not always the existence of a fair trade because of the favoured particular preferences. Hong Kong Chinese were not just suffering from being under a foreigner’s rule but also by the fact that they were not being treated at par with their colonizers in their own homeland. It should be noted that we do not speak of Hong Kong Chinese’s pain as we do of Colonized India’s pain just because Hong Kong was the sixth largest grossing economy. However, one should always remember that the locals were not being benefited by the growing economy, though at the same time one should also not forget Britain’s contribution to making what Hong Kong is today. The writer then introduces his readers to the China factor and its role. China had helped Hong Kong in its processes of decolonization, localization, and internationalization. The decolonization process rapidly made place nearing the last decade of the lease. The basic constitutional reforms were made in such forms that would prepare the power transfer to come place on 1997.

Business ethics Essay Example for Free

Business ethics Essay It is a form of applied ethics or professional ethics that examines ethical principles and moral or ethical problems that arise in business environment. It applies to all aspect of business and is relevant to the conduct of individuals and entire organization. Ethics is mainly concerned with what is good versus bad, what is right versus wrong. Deontology is an ethical theory that holds that actions are right or wrong independent of their consequences. Utilitarianism is an ethical theory that holds that actions are right if they produce the greatest amount of good for the greatest number of people. Corporate social responsibility is the obligation towards the society assumed by business. The business maximizes its positive effects on society and minimizes and its negative effects. An illustration of of an ethical and social responsibility issue related to the textile manufacturing business. In today’s global business where large multinational corporations like the textile industry face charges of violating human rights in third world countries. Using child labor questions the human rights, ethics and social responsibility of the textile manufacturing industry. An analysis of how the textile manufacturing illustration applies to decision making and operations in an ethical and social responsible business. The economic responsibilities of business would produce products that society wants at a price that perpetuates the textile business. The textile manufacturing business decides on legal responsibilities where the obey local state federal and global laws. The textile manufacturing business makes decision based on their ethical responsibilities of meeting other societal expectation written or not written by law. Ethical obligations are a set of â€Å"ought to† standards that define a moral course of action and draw a line between right and wrong. Although ethical obligations in business share similarities with legal rules and regulations in determining how a business conduct itself while striving to make profit and achieve strategic company goals. Ethical obligations are really more about discretionary decisions value guided behavior. For example respecting the religious sentiments and dignity of people while advertising for a product. Legal obligations every business has a responsibility to operate within the laws of the land. Since these laws are meant for the good of the society, a law abiding enterprise is a socially responsible enterprise as well Scope and objectives The scope of ethics indicates its subject matter. Ethics as normative science deals with moral ideal or the good in order to enquire the nature of our conduct. It enquires into the nature of the springs of action, motives, intentions, and voluntary actions and so on. It determines rightness or wrongness of human action. As a science of morality ethics discusses the contents of moral consciousness and the various problems of moral consciousness. Ethics is concerned with the highest good or absolute good. It investigates the nature of its fundamental notions that is right, duty and good. It includes whatever has reference to free human acts, weather as principle or cause of action or as effect or circumstance of action (merit, punishment etc. ) Ethics discuss the nature of human freedom . ethics investigates what constitutes good or bad, just or unjust. It also enquires into what is virtue, law, conscience and duty? What obligations are common to all? What is good in all good acts? These questions lie within the scope of ethics. Objectives: Some of the most common ethical obligations in business relate to recruiting and hiring staff, maintaining safe and healthy work environment use business resources wisely and avoiding situations that have the potential to create a conflict of interest, such as accepting gifts from suppliers or making a hiring decisions not because the applicant has the best qualifications but because the applicant is a relative of the business owner. It also includes considering how and where suppliers get their products and weather to sell the products that are detrimental to the health of customers such as cigarettes and fatty foods.

The Media Access Delay Information Technology Essay

The Media Access Delay Information Technology Essay OPNET Modeller is the network development software. OPNET permits design and learn communication networks, devices, protocols, and application. OPNETs object-oriented modelling stylishness and graphical user interface (GUI) let easy of developing models from the real world network, hardware devices, and protocols. Modeller supports all major network forms and technologies, permitting you to design and test various situations. (Opnet) Introduction I have deliberated various Medium Access Control (MAC) protocols for Wireless local Area (WLAN) Networks. To choose the best one surrounded by the existing protocols, it is necessary to have a network model scenario and some performance metrics on the basis of which they can be assessed. In this paper, various metrics for comparing the performance of MAC protocols and a network model to carry out simulation is discussed. At the end of this chapter, results obtained from the simulation in the form of graphs will be presented. DCF EDCF Metrics Picking the correct metrics or parameters in the evaluation of the QoS (Quality of Service) mechanisms is vital to the result and rationality of the evaluation. The metrics used are Throughput, Access Delay, and End to End Delay in case of real-time multimedia traffic like VoIP, Video streaming (Video conferencing), response time in case of Telnet or Remote Login; type applications which cannot tolerate delay and loss of data. Retransmission Attempts in case a station does not get a chance due to internal collision. The following list below is the item of metrics used: Throughput The Throughput for different priority levels shows how well the QoS schemes can provide service differentiation between the various priorities. The Throughput of all stations shows the utilization of the wireless medium. Wireless bandwidth is a scarce resource, so efficient use of it is vital. Media Access Delay We measure access delay as the time from when the data reaches the MAC layer until it is successfully transmitted out on the wireless medium. The reason for studying average access delay is that many real-time applications have a maximum tolerable delay, after which the data will be useless. Therefore, it is important to provide low delay for real-time flows. Retransmission Attempts Total number of Retransmission Attempts by all Wireless Local Area Network MACs in the network until either packet is successfully transmitted or it is discarded as a result of reaching short or long retry limit. For 802.11e-capable MACs, the Retransmission Attempt counts recorded under this statistic also include retry count increments due to internal collisions. This factor plays important role in Performance of WLAN. Data Dropped Data Dropped due to unavailability of access to medium. This factor largely affects the reliability of WLAN. Simulation Scenario Creating a simulation scenario that is corresponding to real world scenario is the first step of simulation. In this simulation, the wireless topology consisted of several wireless stations and one base station in the wireless LAN. The base station was connected to a wired node (Figure 2.1) which serves as a sink for the flows from the wireless domain. All wireless stations are located such that every station is able to detect a transmission from any other station, and there is no mobility in the system. This means our results will not be impacted by mobility and phenomenon such as the hidden node problem. Figure 2.1 Wi-Fi network models The simulation experiments are carried out using OPNET Simulator version 9.1 on Windows XP SP3. For this simulation, a data rate of 11 Mbps is chosen. Various MAC and PHY (Physical Layer of OSI) parameter values used in our experiment are according to IEEE 802.11e default values given in Table 2.1. We have run the simulation for 5 minutes for each scenario, and then compared the results obtained from them. Figure 2.1 shows a network model for the experiment. Table 2.1: MAC and PHY parameter values used in Experiment ATTRIBUTE VALUE Physical Characteristics Direct Sequence Data Rate (bps) 11 Mbps Transmit Power (W) 0.005 Buffer Size (bits) 256000 BSS Identifier Auto Assigned Channel settings Auto Assigned Roaming Capability Disabled AP Beacon Interval (secs) 0.02 Large Packet Processing Drop Simulation Method To compare the performance of DCF (Distributed Coordination Function) and EDCF (Enhanced Distributed Coordination Function) two scenarios were created; medium access in first scenario was supported by DCF and in second, EDCF protocol was used at the MAC layer. Network environment factors which were used as a benchmark configured same for both scenarios. Detailed specifications are given in the Table 2.1 showing the MAC and PHY parameters used in experiment. The performance evaluation is done by simulating both scenarios one by one in OPNET simulator and then comparing the graphs obtained. Results After choosing metrics, the simulation is done for 5 minutes for a scenario. Then results were gathered. Analysis of EDCF In case of EDCF, all four traffic classes were fed into the MAC layer from higher layer, which are corresponding to AC (0), AC (1), AC (2) and AC (3) respectively to check how efficient the new protocol is to provide service differentiation required for real time application. (Note that DCF does not support service differentiation, so no provision of Access category). For this, in the application profile of scenario (for EDCF protocol) different application was configured for different access category. Details are shown in the Table 4.1. Table 4.1 Access Category corresponding to an application ACCESS CATEGORY APPLICATION CONFIGURED DESIGNATION AC(0) HTTP (LIGHT) BACKGROUND AC(1) REMOTE LOGIN (HEAVY) EXCELLENT EFFORT AC(2) VIDEO CONFERENCING INTERACTIVE MULTIMEDIA AC(3) VOIP INTERACTIVE VOICE In the profile configuration, a profile for clients was configured that uses all the four applications. In simulation scenario, 15 stations were configured to use these services randomly. In the simulation, we assumed that each traffic class has the equal portion of the total data traffic in terms of the average number of packets generated per unit time. The results obtained are as follows: Throughput of Different Access Categories Figure 4.2 Throughputs of Different Access Categories It is observed from figure 4.2 that the Throughput of Access category 3 is way high than the Access category 0 and 1. Throughput for Access category 2 lies in between 3 and 1. It means that Throughput for applications like Voice over IP and Video conferencing, EDCF provides maximum Throughput by providing them more priority over the other services like simple HTTP. Media Access Delay for Different Access Categories Figure 4.3 Wireless LAN Media Access Delay It is observed from figure 4.3 that the Media Access Delay for Access category 3 is at minimum among all Access categories. Media Access Delay for Access category 2 is just 3 to 4 seconds more than AC (3). It means that the medium is assigned to the application according to the priority. Thus, EDCF provides lesser Medium Access Delay for real-time applications. Comparative Analysis of DCF and EDCF Next step is to check the performance of both protocols in terms of Throughput, Media Access Delay, Retransmission Attempts and Data Dropped. These four metrics are determining factors in terms of overall performance of both the protocols. Throughput Figure 4.4 Throughput of DCF vs. EDCF It is observed from figure 4.4 that in the first 30 seconds of simulation, Throughput of both DCF and EDCF is high, but then after that, it decreases with time and stabilizes for both protocols. Throughput in first 30 seconds is high due to less number of Retransmission Attempts (less number of backoffs). From Graph analysis, one fact is clearly visible, that curve of DCF is marginally higher than that of EDCF. We can conclude that DCFs overall Throughput is somewhat more than the EDCF. Retransmission Attempts Figure 4.5 Retransmission Attempts of DCF vs. EDCF It is observed from figure 4.5 that in the first 30 seconds of simulation, Retransmission Attempts for both DCF and EDCF are less, but then after that, it decreases with time and stabilizes for both protocols. Retransmission Attempts in first 30 seconds are less due to less number of backoffs assigned to wireless stations. There is a small noticeable difference between curves of Retransmission Attempts of DCF and EDCF protocol. That small difference implies that the overall Retransmission Attempts made in DCF protocols are a bit lesser than EDCF protocol. Media Access Delay Figure 4.6 Media Access Delay of DCF vs. EDCF In Figure 4.6, for the first minute of simulation the Medium Access Delay for both protocols increases at equal pace, and then after that, DCF suffers somewhat lesser Access Delay than EDCF. The increase in the Medium Access Delay for both protocols is due to increase in the number of nodes competing to gain access of medium. Data Dropped Figure 4.7 amount of Data Dropped of DCF vs. EDCF It is observed from figure 4.7 that the first 30 seconds of simulation, DCF suffers a sudden high Data Drop, but Data Drop in EDCF increases gradually. The reason of varying Data Drop gradually in EDCF is the service differentiation which provides priority based scheme to handle different kind of data. After 2.5 minutes of simulation, curves of Data Dropped of DCF and EDCF remain same for both protocols, EDCF finishes at less Data Dropped than DCF. Conclusions Conclusion The results obtained from simulation shows that Enhanced Distribution Coordination Function provides efficient mechanism for service differentiation and hence provides quality of service to the Wireless LAN. However, this improvement comes at a cost of a decrease in quality of the lower priority traffic up to the point of starvation. The acquisition of the radio channel by the higher priority traffic is much more aggressive than for the lower priority. Higher priority traffic benefited, while lower priority traffic suffered. In terms of overall performance (under the used simulation conditions in this particular study of QoS of Wireless LAN), DCF performs marginally well than EDCF. This happens due to reason that in EDCF mechanism, each AC function acts like a virtual station for medium access, so more collision will be expected for EDCF scenario. But in terms of Quality of Service for real-time applications (like Video conferencing) EDCF outperforms DCF. EDCF has been purposed as the medium access control protocol for IEEEs upcoming standard IEEE 802.11e. Presently, all of the wireless devices use DCF as the default MAC protocol and PCF as the optional functionality.
