Communication studies - Assignment Example A variety of definitions have been produced, yet the attempts to establish a single one seem to be not fruitful (Littlejohn and Foss 3). Thus, considering a few of existing definitions is the best way to understand the essence of the phenomenon. In scholarly literature, communication is considered within three major dimensions: level of observation or, in other words, abstractness, intentionality, and judgment. Within the first dimension, definitions of communication are viewed as broad (for example, communication is a process which relates discontinuous parts of the existing world) or restrictive (communication is a system used to communicate information and orders, through telegraph or telephones). Within the second dimension, the definition includes the dimension of intentionality. For example, communication is a term used to describe situations in which a source transmits a certain message to some receiver with a conscious intent to influence the behavior of the latter. Definitio ns that include judgment present communication within concepts of success, accuracy, effective outcome, etc. For instance, communication is a verbal interchange of some idea or thought (Littlejohn and Foss 4). ... The organizational structure includes employees, departments, their responsibilities, relations, resources, etc (Filipowska et al. 4). Organizational structures may be formal and informal. Virtually every company possesses a formal structure even if it is not strictly adhered to. Most companies also have an informal structure. It suggested that both structures are important for a company’s successful functioning, so it is necessary to learn their intricate characteristics. Formal structure is above all concerned with the existing relationship between authority and the junior. This is known as organizational hierarchy which starts with the most senior person at the top and ends with subordinate employees who are junior to managers of various levels. Informal structure is the one that develops around some project groups or some social groups. It is often grounded on camaraderie, which means people respond immediately and it is easier to continue working (Schatz, n.p.). The struc tures interact with each other in different situations: for instance, when the formal structure ceased to be effective people tend to rely more on the informal one, also working within formal structures, people may complete some tasks within informal structures, which saves time and effort. While communication in any organization is upward, downward, or horizontal (Lunenburg 2), there exist clear differences between the three. Upward communication takes place when the staffs communicate their ideas to a leader with the purpose of inform about some difficulties, clarify some tasks, complain about something etc. Downward communication encompasses communication which goes from higher levels to lower levels of an organization. It is

The Sewerage System In Malaysia Construction Essay

The Sewerage System In Malaysia Construction Essay Sewerage systems are one of the most important infrastructures in construction of residential, industrial or commercial project as it determines the quality of life enjoyed by a community. It consists of a network of underground sewer pipes, pump stations, sewage treatment plants and sludge treatment facilities. This system usually operates based on by gravity due to the slope of the pipe which reduces the high cost required for pumping. Sewers are further classified into a few categories, which depend on the type of wastewater that each of it carries. For example, storm sewers are designed to carry stormwater from roofs, paved areas, pavements and roads; industrial sewers are designed to carry wastewater generate from the industry; sanitary sewers are designed to carry the waste water from cooking and washing and the wastes from toilets. There is another type of sewer which is known as combined sewers. These types of sewers are designed to carry stormwater, industrial wastes, and domestic sewage. In Malaysia, many towns and cities use the separate sewer system. The wastewater is transported in separate pipes from storm sewers, industrial sewers and sanitary sewers. This system will not experience CSOs (Combine Sewer Overflows) which usually happen to combined sewer. The flooding will cause by stormwater only. Sewerage system is very important as it helps people to transport the wastes or sewage away from their places. Therefore, the system must be functioning well because improper functioning system will lead to pollution and contamination of various aspects of our surrounding which affect human life and health. Hence, regular maintenance must be done to the existing sewerage system and appropriate design must be applied to the new sewerage systems to ensure the sewerage systems are in good condition. The efficiency of the sewerage system is affected by the flow of the wastewater. In designing a sewerage system, the type and size of the pipe to be used must be able to accommodate the peak flow. The peak flow is based on the population equivalent which is a direct measurement of the population in an area. When designing the sewerage, there is a standard and criteria that should be followed. The standard code of practice for sewerage design in Malaysia (MS 1228:1991) was adopted from British Standard; BS 8005:1987. However, British Standard may not be as applicable to Malaysia due to the season and climate factor which have direct effect on the peak flow. This is the main reason of doing this research to find out whether the standard is suitable to be used in Malaysia. Problem Statement Any sewerage system will be designed to carry a certain amount of sewage based on the population equivalent (PE). In sewerage design, the per capita flow and the peak flow rate (Qpeak) are important parameters. Based on British Standard, the per capita flow is 225L/day/person and the peak flow factor, K is 4.7. However, a previous study indicated lower per capita flow and peak flow factor in the sewerage system in Malaysia although no conclusive results were obtained (Dayalan, 2007). A lower peak flow factor will result in smaller pipes which will incur lower cost. Therefore, further research is needed to study the suitability of current design criteria for sewerage system located in tropical climates. 1.3Research Objectives The objectives of the study are: To obtain flow data from pre-determined sewer tributary area. To evaluate the parameter in the peak flow factor equation for medium scale sewerage catchment system. To determine the relationship between population of an area to the peak flow of sewerage system. 1.4 Scope of Research To collect relevant information of sewerage design from selected literatures. To find out relevant formula provided in selected codes for sewerage design. To study the peak flow factor in sewer line that serve the PE value of 1000-10000. To measure flow characteristics by using flow meter with build-in sensor in manholes at Tropicana Indah. To compare the results obtained with the formula in the standard code. To make recommendation on the feasibility of the code formula to tropical climate. CHAPTER 2: LITERATURE REVIEW 2.1 Sewerage System in Malaysia The sewerage system is designed to collect wastewater or foul sewage generated from residential, industrial and commercial areas through sewer pipes and discharges it to the treatment plants or facilities to ensure the sewage is released to the natural water bodies in an appropriate condition and quality (Geoffrey, 2004). In Malaysia, sewerage systems range from simple toilet with little or no treatment provided to modern sewage treatment plants that treat the sewage to the desired quality accordance to environment standard. There are two main types of sewerage system in Malaysia. A premise sewerage system is either connected to a public sewage treatment plant or an individual septic tank. Indah Water Konsortium (IWK) is responsible to provide service and maintenance to public sewage treatment plants and all the underground pipes and also provide desludging services to individual septic tanks (Abd Aziz, 2006). IWK decided to divide the underground pipe into two sections, public pipe and private pipe (Figure 2.1) to make sure that all underground pipes operate without any problem. Public pipe is under the responsibility of IWK and the private pipe is under individual responsibility. An individual have to pay for the IWK services when the private pipe need for servicing. (Abd Aziz, 2006). http://www.usj23.com/planet_free/sewage_system/Sewage%20System.jpg Figure 2.1 Flow of wastewater from private pipe to public pipe (USJ 23 Residence 2.2 Transportation of Wastewater Wastewater is usually transported through sewer pipes that are connected to the sewer mains by clay, cast-iron, or polyvinyl chloride (PVC) pipes that range from 80-100mm diameter. The large sewer mains can be located about 1.8m deep or more than that along the centerline of a street or pathway. The small and large sewer pipes are made by different material, in which the smaller sewer pipes are made of clay, concrete, or asbestos cement, and the large sewer pipes are made of reinforced concrete construction. The flow of wastewater is different from water-supply system. The water supply is transported to each house by the application of pressure. However, the wastewater from each house is flows through sewer pipes by gravity. Therefore, the sewer pipe must laid on slope surface to allow the wastewater to flow at a velocity of at least 0.8m/s and not more than 4m/s. (MS1228:1991). If the wastewater flows at velocity lower than 0.8m/s, the solid material tends to settle in the pipe whic h will lead to blockage. Storm-water mains have similar structure as sanitary sewers but they have a much larger diameter than sanitary sewers. In certain places, the urban sewer mains are connected to interceptor sewers, which can then join to form a trunk line. The trunk line will then discharge the wastewater into the wastewater-treatment plant. This transportation process is shown in Figure 2.2. As the interceptors and trunk lines will carry the wastewater discharge from sewer main, they are usually made of brick or reinforced concrete which can carry more load than the other pipe. Sometimes, they are large enough for a truck to pass through them. (Norhan Abd Rahman et.al, 2007) http://techalive.mtu.edu/meec/module21/images/CombinedSewer.jpg Figure 2.2 Transportation of Wastewater (Michigan Environmental Education Curriculum, Wastewater Treatment) 2.3 Concept Theory In designing a sewerage pipe network, the pump stations and sewage treatment plants are required to carry and pump volumetric flow rate. The flow rates are usually measured in cubic meter per second (m3/s) and need to be calculated for both existing land use and for expected future development. There are two parameters that are used to calculate expected flow rates. One of the parameters is per capita flow. This per capita flow of 225L/person/day is an average daily flow, which means a person will produce 225 liters of sewage in a day. Another design parameter named population equivalent (PE) of a catchment can also be used to calculate the flow rate. PE is not a measure of population. However, it is used to measure the estimated number of people that use the sewage facilities. In residential areas, the PE is a direct measurement of the population in an area which is calculated as five per dwelling. The PE has a different method of measurement in commercial area. It is calculated fro m the floor area and this PE value is considered to be proportional to the number of people using a premise during the day which does not reflect the population living in an area. 2.4 Quantity for Wastewater 2.4.1 Tributary Area Tributary area is an area from where the wastewater is being transported to a particular sewer section. The types of activities in that area determine the quantity of wastewater being collected by a particular section. A survey has to be done when there is no information available on existing areas in order to determine the number and classification of persons and the types of industries. (Guyer, 2010) Table 2.1 shows the method of calculating the PE. Table 2.1 Equivalent Population, PE (MS1228:1991) No. Type of Premises/Establishment Population Equivalent (recommended) 1 Residential 5 per unit 2 Commercial: (include entertainment/recreational centres, restaurants, cafeteria, theatres) 3 per 100m gross area 3 School/Educational Institutions: Day schools/institutions 0.2 per student Full residential 1 per student Partial residential 0.2 per student for non-residential student and 1 per student for residential student 4 Hospitals 4 per bed 5 Hotels (with dining and laundry facilities) 4 per room 6 Factories (excluding process wastes) 0.3 per staff 7 Market (Wet Type) 3 per stall 8 Petrol kiosks/Service stations 18 per service bay 9 Bus terminal 4 per bus bay 2.4.2 Sanitary/Domestic Wastes 2.4.2.1 Contributing Population In designing the flow, the population to be used depends on the location of the sewer. The design population in a residential area is based on the number of houses served. However, the design population for an industrial area is the maximum number of staff ever employed. The design population for sewers that serve both residential and industrial areas include residents and non-residents. Designing of these sewers denote that no person should be counted more than once. Allowances should be made for future population changes caused by master planning projections and facility personnel requirements. (Guyer, 2010) 2.4.2.2 Average Daily Flow The average daily flow is counted by multiplying the population equivalent from resident and non-resident with the appropriate per capita flow and adding the two flows generated from both resident and non-resident. The average daily flow shows the total volume of waste generated over a 24-hour period. It cannot be used for wastes that were generated over shorter periods of 8, 10, 12 hours, etc. Therefore, it can only be used for designing sewers that generate wastewater over a 24-hour period (e.g. residential area). In Malaysia, the average daily flow for residential area is usually taken as 225L/person/day. In industrial areas, the average daily flow is taken as 115L/person/day as non-resident personnel and employees is working for 8-hour shifts. These quantities are usually used in designing wastewater treatment facilities. However, they are also used for sizing interceptors, trunk sewers and pumping stations serving large portions of the installation. (Guyer, 2010) 2.4.2.3 Average Hourly Flow Rate Average hourly flow rate is used for designing sewers that serve small areas of the installation (e.g. industrial area), where most of the wastewater is generated by non-residents or other short term occupants. The average hourly flow rate is counted based on the actual period of waste generation. For example, 1000 non-residents with an average daily flow of 115L/person/day would generate 115,000 liters in 8 hours which is equivalent to an average hourly flow rate of 14,375 L/h or 345,000 L/d. However, the average daily flow would still be 115,000 L/d. Therefore, the sewer must be designed hydraulically to carry 115,000 liters of waste in 8 hours instead of 24 hours (Guyer, 2010). If the sewer is designed to carry a waste of 115,000 liters in 24 hours, then the sewer pipe will not be able to transport the wastes as the actual volume of wastes generated is more than the design waste. This will lead to the blockage of sewer pipes and overflow in the toilet. 2.5 Design Wastewater Flow The design flow of wastewater must be determined for any section of a proposed sewer. The design flow is not only based on sanitary sewage; industrial flows, inflow and infiltration must also be taken into account. The following shows the equation to determine the peak flow factor and the factor to be considered in sewerage design. 2.5.1 Design Equations The peak flow required to design sewers, pumping station and treatment facilities are calculated by the following equation: Peak flow factor = 4.7 x p-0.11 p Estimated equivalent population, in thousand. The sewers are designed based on peak flow to ensure that the sewer pipes would be able to accommodate the wastewater generated at any time. 2.5.2 Factors Affecting Sewer Design In designing sewers, there are a few factors as stated in MS1228:1991 that must be taken into consideration: Economy in the design The sewers should be kept as short as possible and avoid unproductive lengths. Shallow rider sewers can be laid under highways having expensive foundations and surfaces to receive the local house connection, and to connect the riders at convenient points into the main sewers. Location of sewers The sewers should be placed within streets or right-of-way to ease the maintenance work. If topography dictates, the sewer is to be located within private properties, and provide adequate access for maintenance purposes. Location or the position of other existing or proposed service lines, building foundation, etc for maintenance purposes. A minimum at 3 m horizontal and 1m vertical separation from the water main should be provided to avoid the sewage from entering the water main. The impact of sewer construction and subsequent maintenance activities towards road users. Hydraulic Design The sewers should be laid at such gradients to produce adequate velocities to convey the solid matter. The gradient should produce a minimum velocity of not less than 0.8 m/s and a maximum velocity of not more than 4.0 m/s to avoid scouring of sewer by erosion action of suspended solid. Structural Design The depth of sewers must be adequate to accommodate the sewage from existing and future properties. The minimum depth should be 1.2 m. The minimum size of the sewer should be 200 mm in diameter in order to convey raw sewage. Straight alignment and uniform gradient between consecutive manholes should be laid for sewers of 600 mm or less in internal diameter while curves can be laid for sewers of larger than 600 mm internal diameter. Flexible type and watertight joints should be provided between sewers, sewer manhole or other appurtenance structure to avoid infiltration and breakage due to differential settlement. The foundation should be able to maintain the pipe in proper alignment and carry the weight of soil above the sewer and any other superimposed load. Service Connection The diameter of the connection must be adequate enough to prevent blockage problems. The sewer must have a minimum gradient of 2%. The minimum size of the connection should be 150 mm. Tee junction should be used to connect service connection to the main sewer. 2.5.2.1 Gravity Sewer Design Sewers are designed to convey the wastewater flows as required. Generally, it is not recommended to design the sewers for full flow, even at peak rates as the chances for problem arising are high. The flows that cover above 90% to 95% of full depths are considered unstable which may lead to sudden loss of carrying capacity with surcharging at manholes as shown in Figure 2.2 (Guyer, 2010). Surcharging means that the pipe that is designed to flow full or partly full, is now transporting the flow under pressure. When the flow exceeds the design capacity, there will be surcharge in the manholes (David and John, 2011). Besides that, large trunk and interceptor sewers laid on flat slopes experience less fluctuation in flow. If it is designed to flow full, the sewers may lack sufficient air space above the liquid for proper ventilation. Ventilation in sewer is important in preventing the buildup of explosive, corrosive or odorous gases, and for reducing the formation of hydrogen sulfide. Th us, the depth of design flow for trunk and interceptor sewers should not exceed 90% of full depth; laterals and main sewers, 80%; and building connections, 70%. Regardless of flow and depth, the minimum sizes of sewer pipes to be used are 150 mm for service connections and 200 mm for all other sewer types. The sewer pipes for service connections are usually smaller than 150 mm as they only convey liquids with little or no solids (e.g. condensate lines). A condensate line of more than 100 mm is recommended for most situations. Same design criteria as sanitary sewers can be applied to industrial application except pipe material that is resistant to the waste are to be specified. (Guyer, 2010) Figure 2.2 (a) Part-full pipe flow without surcharge (b) Pipe flow with surcharge (David and John, 2011) 2.6 Pipe Materials for Gravity Sewer There are many types of material which can be used for sewerage construction. However, the type of materials that we choose must depend on its life expectancy, previous local experience, roughness coefficient, structural strength and local availability. Table 2.2 shows the common materials that are suitable for sanitary sewers. Sewer pipes made by different material have different diameters and lengths. Table 2.2 Pipe Materials for Gravity Sewer Types of Pipe Material Length (m) Diameter (mm) Pipe Joints Vitrified clay pipe (VCP) 0.6 1.0 100 300 Flexible Reinforced concrete pipe 1.83 150 3000 Spigot socket type with rubber rings > 375mm diameter 3.05 Fabricated steel with sulphates resistance cement lining 9 100 1500 Spigot socket, flange and mechanical > 750mm diameter Welded joints Cast iron 3.66 Vary Flange and spigot socket type Asbestos cement pipe 4 100 600 Plastic pipe 6 110 630 Spigot end and socket type with rubber seals, jointing by flanges, welding and solvent cementing Other material CHAPTER 3: RESEARCH METHODOLOGY 3.1 Introduction In this research, a field work will be conducted to get the information that will be used to reach the objectives of this research. 3.2 Preliminary Works This is the initial works that has to be done before conducting the field work at site. It includes information gathering on the topic of sewerage design and self-study on similar and related topics in order to learn more. 3.2.1 Information Gathering A series of books, articles and online information has to be studied to obtain information on the topic of sewerage design. Sources for sewerage design mostly come from abroad. However, the information on the method to evaluate the design criteria is obtained from related research by a local university. 3.2.2 Standard Code of Practice for Design and Installation of Sewerage Systems (MS1228:1991) With the reference to this code book, the design criteria and the factors to be considered for sewerage design is obtained. The equations to calculate the peak flow which depend on the population equivalent are all available in this standard code of practice. 3.3 Site Work A site has been identified for the field work data collection. The location of this site is in Tropicana Indah. Approval is still pending from IWK for access to their manholes. 3.3.1 Flow Characteristics Measurement The flow characteristic of a section of sewerage pipe systems can be measured by using a flow meter. This flow meter is provided with sensor which will automatically record the flow, velocity and water height at a specific time interval, which in this case is 5 minutes. Once the measurement is completed, the data from the flow meter will be linked to a computer that has Flowlink4 software. This software would aid the plotting of graphs for the 3 parameters (flow, velocity and height) as well as transfer of data to other software. From the data, the maximum and minimum hourly flow rate can be obtained. The average flow rate can be used to calculate per capita flow. Flow per capita = Average daily flow (m3/day) / Total population equivalent (PE) = m3/day/person The evaluation of peak factor and per capita flow for sewerage can also be done through the data obtained from field experiment. The equations that are used for sewerage design are as follow: a. Peak flow factor = 4.7 ÃÆ'- p-0.11 b. Average daily flow = Flow per capita ÃÆ'- PE = m3/day c. Peak domestic flow = Peak flow factor ÃÆ'- Average daily flow = 4.7 ÃÆ'- p-0.11 ÃÆ'- Flow per capita ÃÆ'- PE = m3/day From MS 1228:1991, the p value is an estimated PE in thousands and the average flow per capita is 225 L/day/person.

Going Back to the Basics :: Teaching Philosophy Education Essays

Going Back to the Basics Education is a very sensitive topic to discuss among adults. Many adults want the education to be based on a system of ideas that is progressive (which is a system high in the aspect of individuality), some want perennialism (which is the teaching of philosophies that have stood the test of time over hundreds of years), and some, like myself, want to take it back to the way it used to be (essentialism). Education as defined by Webster’s Collegiate Dictionary is â€Å"the action or process of education or being educated.† I believe that the way education was presented in the past worked well and that education should remain to be taught the same. For education to be taught the same as it were in the past, many things have to change. There are too many electives being taught in public schools today, there is too much acceptance on certain things like tardiness, absences, and behavior, there are not severe enough punishments for students who break the rules, and the curricula is too easy. To chance this we need to put a strong work ethic into the children and to do that you need a tough and challenging schedule throughout the schooling process. As a physical educator I would do this by not just rolling out a ball and telling the students to â€Å"play†, but by teaching them certain skills it takes to become a physically fit person. In making a person physically fit, you need to teach them the factors of being fit like: how to eat a healthy diet, how to exercise properly, proper hygiene, and how much sleep to get. I think that the only thing that you get out of education, is what you put in it. To become a smart, balanced, and intelligent person you must put forth all effort in getting an education. To the layperson, education is merely something that needs to be done to get through life and â€Å"to get a good job†, but to me education is making yourself into a better person, and a person who knows what they want out of life. I believe that you need not learn all this extra curricula that is being taught in many of today’s schools like philosophy of ideas, mythology, media, and classes like the printing press.

Mill’s Utilitarianism Analysis Essay

Thesis: Objectors of Utilitarianism states that there is no time for calculating and weighing the effects on utilizing the general happiness. On the contrary, Mill says that mankind has been learning by experience the tendency of actions in order to know what is right and wrong. The rules of morality is improvable, therefore we should pass all that experience on others. However, improving the rules of morality is one thing, but to educate it to the younger is another; since there is still much to learn about the effects of actions on general happiness, and all rational people go through life with their minds made up on the common questions of right and wrong. Reasons: 1. Philosopher and the human: They have to acquire experience about the effects of some actions on their happiness and improving it or at least maintain it. . Traveler: Mill uses the traveler going for his destination as for if a man needs to follow the rules of general happiness, we should open the way and direct him to the knowledge, and not to forbid it. 3. Sailors: They go to sea with it calculated on the Nautical Almanac. Therefore, as for the people, they go on the sea of life with a made up mind on the common questions of right and wrong, and more complicated questions of wise and foolish. Discussion: Mill’s defend against the objectors of Utilitarianism is that the rules of general happiness are made up by the experience of the people. Also, it is improvable by teaching it to the younger and other people. But, he also argues that human are rational creature. Human are capable of answering the questions of right and wrongness by their own experience, and they also capable of learning and experiencing more on their way of life.

Bureaucratic Politics and Intelligence in The Bay of Pigs

In 1961 at the Bay of Pigs, exiles from Cuba performed an amphibious physical attack. The Central Intelligence Agency (CIA) had done the recruitment, training and equipping of these Cuban exiles brigade. Moreover, pilots from America in support of the invasion flew some combat missions. However, in not more than three days, the Cuban president, Fidel Castro, had intervened and crushed the invasion but there were reports of hundred exiles that died. Besides, the assault force survivors spent the subsequent one and a half years languishing in the prisons of Havana.The then U. S. presidents, Kennedy, R. , was troubled within himself for having had approved this operation that morally, intellectually and tactically was bankrupt from its inauguration. Bureaucratic politics, a national security policy models by Graham Allison, helps clarify the dilemmas of Kennedy’s shadowy vacation. The use of analogical reasoning in this ill-fated invasion based on the past successes that were con cealed revealed the faultiness of enacting foreign policies in decision making.The Office of Strategic Services (OSS) may have misguided President Kennedy to result to the wrong policy decisions in dealing with Cuba and her president (Johnson, 1983, 25). Analogical reasoning by the way of process tracing could have aided Kennedy in making up his final decision. Though the press had been informed of the progress of the preparations of the invasion, it downplayed the same more specifically to the Cuban expatriates who had exiled the Miami political representatives in the interest of the national security.Further revisiting the unfolding of events in the Bay of Pigs (Bahia de Cochmos) leaned more on a political outcome than a decision arrived at rationally. The present struggles between the different governments’ officials’ gave birth to this Bahia de Cochmos since each independent side had its priorities, problems and perceptions totally conflicting with the othersâ€⠄¢. This invasion was a unitary rational actor’s unconscious policy decision emerging from coalition, compromise, confusion and competition among the aforesaid officials of the government who had different perceptions of the issue at hand (Blight, 1999, 7).Though no acting solely, these parties were in a common competitive game as elaborated by the model of bureaucratic politics. Endorsements by Eisenhower, an Indian, some staffers and the CIA funding held more significant roles invasion than the chiefs in the determination of the final outcome though they had no elaborate intention in the invasion. For instance, Eisenhower only supported the attempts of destabilizing Cuba while Nixon, a U. S. presidential nominee of the Republicans foresaw the benefits he was to enjoy once the toppling of Castro was successful prior the general elections.Another active participant of the Cuban program included Bissell, a former Yale’s economist and the CIA deputy director who worked t owards the programs expansion. He was determined, having the hopes of being Kennedy’s selected successor, to overthrow the government of Cuba through an amphibious invasion. He later collaborated with Eisenhower to fuel the assault force with heavy firepower. All through even after the eventful inauguration, President Kennedy supported the plan by his issuance of the relevant guidelines though he was doubtful of the invasion success.As the operation matured, various last minute changes had to be adopted. These were a reflection of the hidebound interests of individual players and organizations. Air strikes were prompted with the aim of eradicating on the ground any intervening attempts by the air force in the Castro’s government (Halperin, 1974, 14). The risks facing Kennedy’s political arena equaled those of the military. Confusion and competition between the officials resulted about the operation since each bureaucracy had its own goals that it promoted for it s interests.However, amidst all these, the ruinous upshot exploded. This invasion succeeded because of the collaboration of the bureaucrats. Though Kennedy thought that his infiltration of the Cuban exiles was quiet, the CIA kept the press updated and sent battle communiques to the Cuban political front based in Miami. Kennedy also perceived that was the invasion to face a bounce-back, guerrilla operations would work out. Other stakeholders like the air force staff played it well. The role of intelligence in the InvasionIntelligence calls for use of analogical reasoning and the utilization of the history properly in coming up with decisions especially foreign policy decisions. However, of the two reasoning by analogy seems to take a greater portion. In the Bay of Pigs, Kennedy placed less trust in advice given to him and suggestions from various administrations. For instance, he chose to independently deal with the Laotian foreign policy resolutions when the joint chiefs and the sta ffers seemed to be reluctant in updating him the happenings in the Bay of Pigs.He goes further to reflect on the European crises and not only the crisis in Cuba on missiles. Robert Kennedy stands out to be a statesman capable of escaping single analogy confines. Although a foreign policy maker, Kennedy employs historical reasoning in his policy decision making and this proves to be superficial as compared to reasoning by analogy. Besides, it is an ordinary phenomenon. The problems that were at hand in Cuba invasion could not have been perceived and recognized since the stakeholders merely made observations and their reasoning was logical with no analogical reasoning.They never referred from the past similar incident’s problems in order to handle the current in a more reasonable manner. Even though Kennedy was sympathetic with the operation’s motives and had no apprehensiveness about Castro’s overthrowing by the U. S. , the CIA plan was never persuasive to him. H e was focused on the probabilities of accomplishing the operation and also attaining political success (Vandenbroucke, 1984, 7). He favored smaller teams infiltration than undertaking an amphibious assault.The CIA managed to maneuver tactfully and shrewdly in the operations preparation and execution without loosing. This agency enjoyed the information monopoly on the Cuban issue. Furthermore, its officials were more passionate about the problem than the rest thus remained to be very convincing to the others. Besides, other key players like Bissell, a doctorate degree holder, with their divergent values, goals and stakes and power resources had reliable decision inputs.
