Environmental Effects Of Global Warming Essays - Climate Change

Environmental Effects Of Global Warming Environmental Effects of Global Warming The greenhouse effect and global warming are issues that are talked about by geologists all the time. The greenhouse effect is a natural process that keeps the earth at temperatures that are livable. Energy from the sun warms the earth when its heat rays are absorbed by greenhouse gasses and become trapped in the atmosphere. Some of the most common greenhouse gasses are water vapor, carbon dioxide, and methane. If there were no greenhouse gasses, very few rays would be absorbed and the earth would be extremely cold. When too many rays are absorbed, the earths atmosphere starts to warm, which leads to global warming. Americans are the leading cause for this phenomenon and our behavior is leading to many problems that are affecting the environment in which we live. In order to talk about global warming, we must first learn what causes the greenhouse effect. A lot of the rays from the sun are absorbed by water vapor that is naturally in our atmosphere. Water vapor accounts for 80 percent of natural greenhouse warming. The remaining 20 percent is due to other gasses that are present in very small amounts (Murck, Skinner and Porter 488). Carbon dioxide is also a big absorber of the suns heat rays. Humans can cause a lot of carbon dioxide to be released. Every time we burn fossil fuels, we release more carbon dioxide. Emissions from cars also increase the Rounds 2 amount of carbon dioxide in the atmosphere. If there is more carbon dioxide in the atmosphere more rays from the sun are absorbed. This will cause the atmosphere and the earths temperature to warm. The warming of the earth will cause the oceans to become warmer. When they heat up, more water is evaporated, causing more carbon dioxide to be released into the atmosphere. Once this process starts, it is extremely hard to control. If the temperature keeps rising, more carbon dioxide will be released. Another greenhouse gas is methane: Methane absorbs infrared radiation 25 times more effectively than carbon dioxide, making it an important greenhouse gas despite its relatively low concentration (490). There have been many studies on how methane is released into the atmosphere. Methane in the atmosphere is generated by biological activity related to rice cultivation, leaks in domestic and industrial gaslines, and the digestive process of domestic livestock, especially cattle (490). An environmental effect of global warming is the fact that higher temperatures will lead to a change in the water cycle. Some places may experience more rain. Warmer temperatures will cause a greater amount of evaporation from lakes, rivers, and oceans. In some areas this could be good, and in others it could be considered bad. In northern regions of the United States, an increase in the temperature and amount of rain could actually extend the growing season of crops. This would in turn mean more money for farmers in the northern region. It could also hurt some farmers. Too much rain is bad for some crops. Certain areas will actually get less rain, which would lead to more droughts and have a negative impact on crops. Warm and wet weather is usually a factor Rounds 3 that promotes tropical storms. Global warming would lead to tropical storms appearing with greater frequency. More rain will also force plant life to adjust. Forests and plant life migrates naturally, but scientists say that global warming would cause them to migrate at a much faster rate. If the climate changes the Intergovernmental Panel on Climate Change says, some forest species in North America will shift by as much as 300 miles to the north (www.pirg.org/enviro/global_w/fact.htm). If a region is getting more rain and plants on the border of that region need rain to survive, they will naturally begin growing in the new region. The Environmental Media Services Organization has found that the greenhouse effect could drive global temperatures up as much as 6 degrees by the year 2100 - an increase in heat comparable to the 10 degree warming that ended the last ice age (www.ems.org/climate/sub2_html). If a ten-degree warming was the factor that ended the ice age, imagine what another warming by about that same amount

Definition and Examples of Sententiae in Rhetoric

Definition and Examples of Sententiae in Rhetoric In classical rhetoric, a  sententia  is a maxim, proverb, aphorism, or popular quotation: a brief expression of conventional wisdom. Plural: sententiae. A  sententia, said the Dutch  Renaissance humanist  Erasmus, is an adage  that bears particularly on â€Å"instruction in living (Adagia, 1536). See Examples and Observations below. Also see: 2,000 Pure Fools: An Anthology of AphorismsCommonplaceEnthymemeLogosWhat Is a Maxim? EtymologyFrom the Latin, feeling, judgment, opinion Examples and Observations It is best to insert sententiae discreetly, that we may be viewed as judicial advocates, not moral instructors.(Rhetorica ad Herennium, c. 90 BC)A mans as miserable as he thinks he is.(Seneca the Younger)No man is laughable who laughs at himself.(Seneca the Younger)Things forbidden have a secret charm.(Tacitus)Greater things are believed of those who are absent.(Tacitus)A bad peace is worse than war.(Tacitus)Post-Ciceronian Latin gave vigor and point to style by the frequent use of sententiaeclever, sometimes epigrammatic, apothegmatic turns of phrase: what oft was thought but ner so well expressd, as Alexander Pope was to put it. Quintilian devotes a chapter to sententiae (8.5), acknowledging that they had become a necessary part of the orators art.(George A. Kennedy, Classical Rhetoric. Encyclopedia of Rhetoric. Oxford University  Press, 2001)Sententiae in the Renaissance- A sententia, which had overtones of its classical Latin sense of judgement, was a pithy and memorable phrase : a recitall of some grave matter which both beautified and graced a style. Several writers were clear that testimony could take the form of a Notable sentence or was a sententia of a witness. Richard Sherry, in his Treatise of Schemes and Tropes (1550), closely associated the sententia with the argument from testimony or authority when he defined it as one of the seven kinds of figure called Indicacio, or authoritie.(R.W. Serjeantson, Testimony. Renaissance Figures of Speech, ed. by Sylvia Adamson, Gavin Alexander, and Katrin Ettenhuber. Cambridge University  Press, 2008)- Scholasticism developed around the medieval tendency to treat ancient sourcesboth the Bible and certain texts of classical antiquityas authoritative. So strong was this tendency that individual sentences from a respected source, even when taken out of context, could be employed to secure a point in debate. These isolated statements from ancient sources were called sententiae. Some authors collected large number s of sententiae into anthologies for educational and disputational purposes. Disputes centered on debatable points suggested by one or more sententiae, these debatable notions being called quaestiones. Education by debating general topics drawn from authoritative statements reveals one way in which rhetorical and dialectical practices made their way into the Middle Ages. . . .Writers now known as the Italian Humanists were responsible for a resurgence of interest in the languages and texts of classical antiquity during the Renaissance period, an orientation referred to as classicism. . . .[T]he Humanists sought to place the text in its historical context, in order to establish the correct value of words and phrases. . . . As noted [above], the scholastic practice of splintering classical sources into individual statements or sententiae led to the loss of original meaning and even of authorial identity. Charles Nauert writes, from Petrarch onward, humanists insisted on reading each o pinion in its context, abandoning the anthologies . . . and subsequent interpretations and going back to the full original text in search of the authors real meaning.(James A.

Supply chain management Case Study Example | Topics and Well Written Essays - 1000 words

Supply chain management - Case Study Example The marketing area of Chemtech is primarily concerned with taking orders from the customer for their next month’s requirement. It then makes forecast and relays the same to the purchase department for timely delivery of the same. The department feels that lack of effective planning by supply chain management is responsible for the problems in meeting the customers’ demands. Answer 2 Chemtech needs to streamline its coordination between the departments and ensure that the logistic planning for at least three months is made in advance. This would give the suppliers more time to make arrangements for slow moving products as well as ensure availability of inventory that is often required at short notice. The company should also show more confidence on its long term suppliers and help understand their problems. Logistics and supply chain is vital part of business strategy and therefore concerted efforts for efficient receipt and delivery of goods and services need to be impl emented. Effective computerization of its various in house operations and functions would ensure smooth flow of information leading to improved performance outcome. The computerization would also help to forecast the products requirement so that it can maintain the inventory and meet the requirements of the customers at short notice. Answer 3 The suppliers like Potash should seek trust and at least three months time from its customers like Chemtech for delivery of products which are slow moving. The repeated threats of change in the suppliers by Chemtech have also significantly lowered the morale of Potash. As a result, the company has also started looking for fresh long term customers who could give them realistic time margin to meet their demands. The three months advance order would also enable the company to increase its stock of products which could be required by customers at short notice. While suppliers maintain large stock of products that are in high demand, the short supp ly of slow moving products often becomes huge liability for them. Hence, longer lead time for such products would facilitate the suppliers to coordinate its own logistics and supply chain. The linkages with external agencies are important part of logistics and supply chain management. Thus companies that are able to develop trust and mutual understanding would greatly benefit from long term relationship. (words: 500) Case study 15.1 Answer 1 There general challenges and issues

What Are the Ways of Controlling and Treating International Employees Essay

What Are the Ways of Controlling and Treating International Employees - Essay Example It is evidently clear from the discussion that in the 21st century, many business organizations have laid down strategies to the international market in an effort to increase their business profitability. As domestic markets become saturated, most business firms create an international strategy to invest in growing markets for their products. While new market segments provide organizations with opportunities to grow, they pose a great challenge to the management and these challenges may lead to the failure of these organizations. International market segments have unique business characteristics, customer demands, regulations, and cultural differences. In principle, international markets require unique approaches due to the variation in market characteristics. The concept of international employees has gained more attention as companies anticipate meeting workers from different countries and who differ in terms of work attitude, culture, religion, color, and race. All these factors b ecome increasingly important as companies venture in international markets where the employee mix becomes increasingly complex. The managers are faced with the challenge of accommodating the differences of international employees and adopting tactics to ensure that they work harmoniously within the same organization. Effective leadership strategies are essential for managers to control and treat international employees and to ensure that they are aligned with the organizational goals. The role that employees play within an organization is crucial and this explains why international companies must pay keen attention to employee coordination within the workplace. Employees are major stakeholders within an organization and the role they play has a direct impact on the organization output.

Key Factors Affect In Car Buying In Shanghai Dissertation

Key Factors Affect In Car Buying In Shanghai - Dissertation Example There were also several corporations that distorted the place of factories in China from dispensation trade bases to production bases for domestic supply depending on the market expansion. In the case of processed food manufacturers, the position of Chinese factories thus far was to process worldwide procured raw materials in China and export them to Japan. This approach is based on the opinion concerning modify in the consumer market that the insist for processed food will produce because there are many dual-income families and families in China often go out for Long routed drive (Kim, L., 2003, 506-521). Findings Consumer market growing at multiple levels According to the latest research, In the Chinese market, the purchasing power of heart income earners and over is increasing in the urban areas of coastal regions. In addition, incomes are rising in the urban areas in the inland and northeastern regions, and consumer behavior is ahead momentum in wide-ranging regions and income groups. At the same time, though, it has become clear from this study that there are lots of factors that cannot be precise by averages, such as differences in consumer behavior in the urban and rural areas in the Chinese market as well as disparities in consumer behavior by income group inside cities as well. Retailers such as Car dealers that have entered the Chinese market have seen strapping business results in China, which has acceded to the WTO and is rapidly making progress in deregulation.

Devadasi System in India

Devadasi System in India Commonly known as dancing girls or temple girls is a system that has come in to existence for more than thousand years. When the great tamil kings belonging to the erstwhile Chola, Chera and Pandya Kings built huge temples for their gods, they felt that there is a need to maintain these temples in a proper way and thus need full time devotees to take care of the diety and the temple premises. One other angle given to constructing Huge temples are to protect the people from flood, cyclone or any other natural disaster. In other words, temples are meant to be shelter for the people of that area from natural disasters. Hence they appointed girls to maintain these temples. The main function of these girls are to sing and performing dances and taking care of the diety. They are considered to be the wives of the gods in the temple in which they are appointed. They are not allowed to marry any mortal man during their life time. These girls are held in High esteem as they are considered to b e close confident of the god. The dance which they perform is famously known as Barathanatyam the most famous dance form of South India. This practice of dedicating girls to deities are commonly known as Devadasi System and the girls thus dedicated are known as Devadasi which is a Sanskrit word or Thevaradiyar which is a Tamil word that literally means female slaves of the god. As mentioned above these Devadasi are expected to be experts in Music and Dance. As years passed their service shifted from gods to earthly gods and lords . They are forced to do service not only to the deities, but also to the landlords and rich devotees of the deities. In short, they started living the life of a prostitute with religious sanction and customary backing. Initially this system was prevalent only among the upper caste Hindus particularly of the Brahmin community . The British colonization of India brought major change in the religious and cultural fabric of India. The upper caste Brahmins occupied major positions in British rule and were able to recognize the dance performed by Devadasi as Bharatanatyam and were able to give a cultural supremacy for this form of dance, thus bringing out devadasiss to main stream of life. However, the Brahminical Hindu Religion which is known for its Caste imbalances and discrimination against the lower caste sowed the seeds of the system into economically, politically and socially disadvantaged lower caste Dalit Hindus. This system started spreading its tentacles to other parts of the country in different forms and names such as Bogams in Andhra Pradesh, Jogatis or Basavis in Karnataka, Thevaradiyar in Tamil Nadu, Muralis in Maharashtra, Maharis in Kerala. Dalits dedicated their girls to the Diety mainly because of two reasons one is because of the superstitious belief that it will bring glory to their family and their village, the other one is the economical reason that it is very difficult for the parents to marry of their daughter because of the prevalent dowry system and also if they dedicate the girl to the Diety, their family will be taken care of by the village rich man to whom the girl do the sexual favours in the name of the Diety. Over a period of time, this practice has represented a clear violation of Human Rights with these Dalit Devadasis were dedicated with a hidden object of performing sexual favours to initially upper caste Hindus and then they become a public property forcing them to enter prostitution. They are also not allowed to marry any man of their choice and often fell a prey into the hands of Broker agents representing brothels from Mumbai and other areas. Several movements India is a party to a number of Human Rights Instruments like that of International Covenant of Civil and Political Rights 1966, The International Covenant for Economic, Social and Cultural Rights 1966, The International Convention for the Elimination of All forms of racial Discrimination 1966 which advocates for among others, equal rights for women and prohibits racial discrimination in any count. Added to that provincial states in India has enacted legislation like The Bombay Devadasi Act 1934, The Devadasi(Prevention of Dedication) Madras Act 1947; The Karnataka Devadasi (Prohibition of Dedication) Act, 1982 to tackle this menace of Devadasi System. Irrespective of this, it is widely reported that this system prevails in some parts of India particularly among the Dalit community. This paper attempts to find out the root causes of the system and the reason why this system is still prevalent in India. Accordingly, this paper is divided into four parts, the ongoing is the first part that introduces the topic, Part II deals with the History and Origin of Devadasi System, Part III deals with the Social movements that fought against the Devadasi system, Part IV analyses Indias obligation to eradicate the system in line with the international obligation which it assumed through various treaties and finally part IV concludes with recommendations to eradicate the same. DEVADASI SYSTEM AND VIOLATIONS OF HUMAN RIGHTS: STATUS OF INDIAS LEGAL OBLIGATION Devadasis could face discrimination on three counts viz as a woman, as a Dalit and sometimes as a child. International community has time and again tried to address the issue by way of multilateral Conventions/Treaties making member states to eliminate these kind of discriminations. Accordingly a number of International Instruments are made at the international level to address these menace which includes the Universal Declaration of Human Rights (UDHR), the International Covenant for Civil and Political Rights (ICCPR), the International Covenant for Economic Social and Cultural Rights (ICESCR), the International Convention for Elimination of Racial Discrimination (ICERD), the Convention on the Elimination of all forms of Discrimintion against Women (CEDAW). One of the purposes of the United Nations is to achieve international co-operation in promoting and encouraging respect for human rights and for fundamental freedoms for all without distinction as to race, sex, language or religion and to be a centre for harmonizing the actions of nations in the attainment of this purpose. Art 1 of the Universal Declaration of Human Rights states that all human beings are born free and equal in dignity and rights. Art 2 further bestows rights upon individuals without distinction of any kind, such as race, colour, sex, language, religion, political or other opinion, national or social origin, property, birth or other status. Similarly Art of the International Covenant for Civil and Political Rights 1966, prohibits discrimination of any kind including discrimination based on social origin . Art 2(1) of ICCPR mandates the state parties to ensure to all individuals within its territory and subject to its jurisdiction the rights recognized in the present covenant. Art 2(2) requires the state parties to adopt such legislative or other measures as may be necessary to give effect to the rights As mentioned above, India is a founding member of these Conventions. However India has not till date enacted any enabling legislation to implement the same in the domestic sphere. Without an implementing legislation Indian courts may not be able to enforce the provision of these treaties in the domestic realms. Needless to say, Treaties are considered to be the main source of international law. When it comes to human rights, treaties play an important role. Human rights treaties have contributed to the development of customary rules and general principles of international law. They create obligations not only among parties but also between parties and individuals. More important, these treaties have become a source of inspiration to many judges and lawyers in their interpretation of domestic legislation. Some international organizations grant their membership only to those states, which. ratify certain human rights treaties. The ratification of human rights treaties demonstrates the ratifying states adherence to civilised standards. As a result, a states credentials in international society depend in part a1 least on the acceptance of and compliance with its obligations under human rights treaties. Thus the ratification of Human Rights treaties by India may be seen as an act to outshow the world that it is a civilized nation thus avoiding isolation in international Human Rights diplomacy. But the non-enactment of a domestic enabling legislation alone cannot be considered as failure on the part of the member state to fulfill the international obligation which it assumed by way of treaty. A state may not go for the enactment of domestic legislation if it is satisfied with its existing legislative mechanism that the legislation in place are sufficient enough to tackle the menace. In this regard it is imperative to look and analyse the legislative mechanism in India aimed at the abolition of the system of Devadasi. Indian Constitutional and Legal Provisions relating to Womens Rights Indian Constitution contains several provisions relating to women and children. However equality and freedom has always been neglected in the name .of custom, honour, family welfare and social prestige. Equality that is guaranteed in the constitution of India is a dynamic one. While hoping for the ideal of equality, it does not recognise the realities of inequalities. Article 14 of the Constitution recognises equality before law for all citizens without any discrimination. Article 15 prohibits discrimination on grounds of religion, race, caste, sex or place of birth. Article 15 (3) says about protective discrimination to women and children and Article 21 says about the protection of life and liberty to all. The Constitution also ensures protection against traffic in human beings and forced labour. Art 42 says about provisions for just and humane conditions of work and maternity relief. The protection for women in the work place is given in factories Act 1948. It includes several welfare regulations and protective measures for women and children in working places, section 125 of criminal procedure code 1973 provides maintenance to women. Indian penal code Sections 509, 294 and 354 deals with Eve-teasing and sexual Harassment. The Indecent Representation Of women (protection) Act, 1986 for preventing the depiction of a woman in a manner which is derogating or denigrating to women, or which is likely to corrupt public morality through advertisement. Publications, writings, paintings, figures, or in any other manner. Indian Judiciary was also pro-active in guarding womens rights in general. In some of the leading cases such as In State of u.P. v. Boden Sundara Rao the Apex Court came down h eavily on the High Court of Andhra Pradesh for awarding grossly inadequate sentence in the following words: Crimes against women are c;m the rise. Imposition of grossly inadequate sentence and particularly against the mandate of the legislature not only is an injustice to .the victim of the crime in particular and the society as a whole in general, but also at times encourages a criminal. The courts must not only keep in view the rights of the criminal but also the rights of the victim of a crime and the society at large while considering importance of appropriate punishment. In Vishaka v. State of Rajasthan. The Vishaka, an Organization working for the welfare of the women, moved toSC when a social worker was gangraped in Rajasthan. While deciding the case the Supreme Court brought the international conventions in Indian Law. How they are trying to incorporate it is very well understood from the words. . Some Provisions in the CEDAW-Arts 11 and 24 as also general recommendations of CEDAW in this context-articles 11, 22, 23, 24 as ratified in the present context are of significant. According to the Supreme Court, Sexual harassment includes such unwelcome behaviour (whether directly or by implication) as: (i) physical contact or advances: (ii) a demand to request for sexual favours; (iii) sexllally co loured remarks; (iv) showing pornography; (v) any other unwelcome physical, verbal or non-verbal conduct of sexual behaviour. Though the Indian system is quite effective in protecting the Womens rights, it served limited purpose in protecting women who are Devadasis particularly from the Dalit community. Needless to say there were several legislations which prohibited this system and provided rehabilitation for the same.

History of Computers :: Technology Computers Essays

History of Computers When you think about the origins of the electronic digital computer, what scientists’ names come to mind? Many historians give the credit to the American scientists J. Presper Eckert and John W. Mauchy. They built their Electronic Numerical Integrator and Computer (ENIAC) during World War II. These two scientists founded the first private computer systems company. Although most people recognize Eckert and Mauchy as the persons accountable for the computer industry, historians are beginning to recognize a more unfamiliar history of the computer, its roots in the military establishment. (Meyers) The birth of the abacus was the beginning of computer history. The abacus is a wooden rack that holds two horizontal wires with beads strung on them. Moving the beads on the abacus can solve regular arithmetic problems. Thomas of Colmar developed the desktop calculator. While great advances were made in mathematical physics between 1850 and 1900, mechanical engineering and science began to make important advances in several areas by the time WWI broke out in 1939. The Navy was particularly interested in the development of advanced technology beginning in World War I. â€Å"Important advances in naval warfare, including the use of mechanical directors and computers for fire control, the use of radio for communication across great distances, and the development of the attack submarine posed new technical problems for strategists.† (Flamm) A consulting board was set up in order to screen the proposals of outside inventors. The board also set up a laboratory to work on the problems of antisubmarine warfare, and eventually the Naval Research Laboratory was then established in 1923. The development of RADAR, radio communications, and the interception of encrypted enemy communications traffic were all supported by the Navy’s postwar research efforts. â€Å"Because signals transmitted by radio could be intercepted much more easily than communications over land lines, cryptanalysis became an economic means of acquiring in telligence about the intentions of foreign, especially naval, military forces.† (Flamm) During the 1930s, the Navy supported substantial work on servomechanisms at MIT. The analog computers were developed after Navy officers enrolled as graduate students in MIT’s Servomechanism Laboratory.

Software Security Risk Analysis Using Fuzzy Expert System

Since we have not seen a software system that is completely secure, there is need to analyze and determine the security risk of emerging software systems.This work presents a technique for analyzing software security using fuzzy expert system. The inputs to the system are suitable fuzzy sets representing linguistic values for software secu rity goals of confidentiality, integrity and availability. The expert rules were constructed using the Mamdani fuzzy reasoning in order to adequately analyze the inputs. The defuzzication technique was done using Centroid technique. The implementation of the design is done using MATLAB fuzzy logic tool because of its ability to implement fuzzy based systems.Using newly develop software products from three software development organizations as test cases, the results show a system that can be used to effectively analyze software security risk. ANALYSIS AND DESIGN The design is basically divided into four stages: 1) DESIGN OF THE LINGUISTIC VARIABLES The inputs to the system are the values assumed for the software security goal thru confidentiality, integrity and availability. The goals are assumed to be the same weight and a particular valued is determined for each of them based on questions that are answered about the specific software.Also the values determined for each of the inpu t are defined as a fuzzy number instead of crisp numbers by using suitable fuzzy sets. Designing the fuzzy system requires that the different inputs (that is, confidentiality, integrity, and availability) are represented by fuzzy sets. The fuzzy sets are in turn represented by a membership function. The membership function used in this paper is the triangular membership function which is a three point function defined by minimum, maximum and modal values where usually represented in 1. [pic]Figure 1: Triangular Membership Function 2) THE FUZZY SETS The level of confidentiality is defined based on the scales of not confidential, slightly confidential, very confidential and extremely confidential. The level of integrity is also defined based on the scales very low, low, high, very high, and extra high. Also, the level of availability is also defined by the scales very low, low, high, very high and extra high. The levels defined above are based on a range definition with an assumed int erval of [0 -10]. The ranges for the inputs are shown in tables 1 and 2. DESCRIPTION |RANGE | |Non-Confidential |0-1 | |Slightly Confidential |2-3 | |Confidential |4-6 | |Very Confidential |7-8 | |Extremely Confidential |9-10 | Table 1: Range of inputs for Confidentiality Very Low |Low |High |Very High |Extra High | |0 – 1 |2 – 3 |4 – 6 |7 – 8 |9 – 10 | Table 2: Range of inputs for Integrity |Very Low |Low |High |Very High |Extra High | |0 – 1 |2 – 3 |4 – 6 |7 – 8 |9 – 10 |Table 3: Range of inputs for Availability |DESCRIPTION |RANGE | |Not Secure |0 – 3 | |Slightly Secure |4 – 9 | |Secure |10 – 18 | |Very Secure |19 – 25 | |Extremely Secure |26 – 30 | Table 4: Level Of Security RiskThe fuzzy sets above are represented by membership functions. The corresponding membership functions for confidentiality, integrity and availability are presented in figures below [pic] Figure 1 : Mem bership functions for Confidentiality Similarly, the output, that is, the level of security risk is also represented by fuzzy sets and then a membership function. The level of security risk is defined based on the scales: not secure, slightly secure, secure, very secure, and extremely secure within the range of [0- 30].The range definition is shown in table above. The membership function for the output fuzzy set is presented in figure below. [pic] Figure 2 : Membership functions for Integrity [pic] Figure 3 : Membership functions for Availability [pic] Figure 4 : Level Of Security Risk 3) THE RULES OF THE FUZZY SYSTEM Once the input and output fuzzy sets and membership functions are constructed, the rules are then formulated. The rules are formulated based on the input parameters (confidentiality, integrity, and availability) and the output i. e. level of security risk.The levels of confidentiality, integrity, and availability are used in the antecedent of rules and the level of sec urity risk as the consequent of rules. A fuzzy rule is conditional statement in the form: IF x is A THEN y is B. Where x and y are linguistic variables; and A and B are linguistic values determined by fuzzy sets on universe of discourses X and Y, respectively. Both the antecedent and consequent of a fuzzy rule can have multiple parts. All parts of the antecedent are calculated simultaneously and resolved in a single number and the antecedent affects all parts of the consequent equally.Some of the rules used in the design of this fuzzy Systems are as follow: 1. If (Confidentiality is Not Confidential) and (Integrity is Very Low) and (Availability is Very Low) then (Security Risk is Not Secure). 2. If (Confidentiality is Not Confidential) and (Integrity is Very Low) and (Availability is Low) then (Security Risk is Slightly Secure). 3. If (Confidentiality is Extremely Confidential) and (Integrity is Extra High) and (Availability is High) then (Security Risk is Slightly Secure). †¦ †¦Ã¢â‚¬ ¦. 125.If (Confidentiality is Not Confidential) and (Integrity is Very Low) and (Availability is high) then (Security Risk is Extremely Secure). The rules above were formulated using the Mamdani max-min fuzzy reasoning. DEVELOPMENT AND IMPLEMENTATION The linguistic variables were determined with the extent of the positive and negative responses to a well constructed security questions that are presented in form of on-line questionnaire. As it was mentioned earlier, MATLAB was used for the implementation. The linguistic inputs to the system are supplied through the graphical user interface called rule viewer.Once the rule viewer has been opened, the input variables are supplied in the text box captioned input with each of them separated with a space. a) THE FIS EDITOR The fuzzy inference system editor shows a summary of the fuzzy inference system. It shows the mapping of the inputs to the system type and to the output. The names of the input variables and the processing methods for the FIS can be changed through the FIS editor. Figure 5: The FIS editor b) THE MEMBERSHIP FUNCTION EDITOR This can be opened from the command window by using the plotmf function but more easily through the GUI.The membership function editor shows a plot of highlighted input or output variable along their possible ranges and against the probability of occurrence. The name and the range of a membership value can be changed, so also the range of the particular variable itself through the membership function editor. [pic] Figure 6: The Membership Function editor c) THE RULE EDITOR The rule editor can be used to add, delete or change a rule. It is also used to change the connection type and the weight of a rule. The rule editor for this application is shown in figure 7. pic] Figure 7: Rule Editor d) THE RULE VIEWER The text box captioned input is used to supply the three input variables needed in the system. The appropriate input corresponds to the number of YES answer in the questionnaire for each of the input variables. For example, in the figure 8, all the input variables are 5 and the corresponding output is 13. 9, which specified at the top of the corresponding graphs. The input for each of the input variables is specified at the top of the section corresponding to them, so also the output variable.The rule viewer for this work is presented in figure 8. [pic] Figure 8: The Rule editor e) THE SURFACE VIEWER The surface viewer shown in figure 9 is a 3-D graph that shows the relationship between the inputs and the output. The output (security Risk) is represented on the Z-axis while 2 of the inputs (Confidentiality and Integrity) are on the x and y axes and the other input (Availability) is held constant. The surface viewer shows a plot of the possible ranges of the input variables against the possible ranges of the output. 4) EVALUATIONThe security risk analysis system was evaluated using three newly completed software products from three different s oftware development organizations. The output determines the security level of software under consideration. The summary of the evaluation is given in figure 11. For product A, 5 is the score for confidentiality, 5 for the integrity and 5 for the availability. |Software |Input |Output |Significance |Security Level | |Product A |5 5 5 |13. |45% slightly secure, 55% secure |46. 33 % | |Product B |8 7 8 |24. 2 |20% secure, 80% very secure |80. 60 % | |Product C |10 10 10 |28. 4 |35% very secure, 65% extremely secure |94. 67 % | Table 5 : Evaluation of Different Input Variables [pic] Figure 9 : The Surface Viewer [pic] Figure 10 : Histogram & 3D CONCLUSION AND FINDINGThus, this work proposes a fuzzy logic-based technique for determination of level of security risk associated with software systems. Fuzzy logic is one of the major tools used for security analysis. The major goals of secure software which are used as the inputs to them system are the preservation of confidentiality (preven ting unauthorized disclosure of information), preservation of integrity (preventing unauthorized alteration of information) and preservation of availability (preventing unauthorized destruction or denial of access or service to an authentic user).It might be necessary to redesign this system in a way that it will be deployable and will be without the use of MATLAB. It might also be necessary to use an adaptive fuzzy logic technique for security risk analysis. We have been able to design a system that can be used to evaluate the security risk associated with the production of secure software systems. This will definitely help software organizations meet up with the standard requirements. A technique for assessing security of software system before final deployment has been presented.The result of this study shows that if the software producing companies will incorporate security risk analysis into the production of software system, the issue of insecurity of software will be held to the minimum if not eliminated. This study has also revealed that if each of the software security goals can be increased to the maximum, then the level security will also be increased and the risk associated will be eliminated. Finally, security risk analysis is a path towards producing secure software and should be considered a significant activity by software development organizations.

Bob Roberts essays

Bob Roberts essays The movie Bob Roberts is a political satire based on one mans campaign for a seat in the Senate. A British documentary crew is on hand to film Roberts' campaign and captures the frightening possibilities of a steamrolling campaign and all it can experience along its trail to Washington. Of course Bob Roberts the character is about as real as an honest politician, however the film's fiction comes closer to fact than many of todays politicians would like us to believe. Writer-director Tim Robbins plays Bob Roberts in this thought-provoking dramatic and political satire about a 1990 Pennsylvania race for the U.S. Senate. At first, it's easy to laugh at Roberts' phony-baloney public facade as he strums pro-capitalist folk songs such as "I Want to Be Rich" and "This Land Was Made for Me." Later, though, the laughs fade as we get a glimpse behind Roberts' hospitable mask and witness a snake pit of guns-for-drugs trades, cash looted from failed savings-and-loan institutions and ex-CIA campaign managers. A documentary filmmaker is along for the ride and captures Roberts sound-bite campaign against liberal incumbent Senator Brickley Paiste (Gore Vidal.) The rest of the cast is sprinkled with such notable actors as James Spader, Helen Hunt, Susan Sarandon, Fred Ward and Peter Gallagher in cameo roles. Most of them play television news reporters that are as biased as Bob Roberts campaign is crooked. This is how the film allows the media to portray itself throughout. During the film the media is very biased towards both campaigns. One particular example of this is when Bob Roberts is about to go on the show Good Morning Philadelphia. Right before he goes on, the host of the show tells him that she does not support his views. This leads to the two of them having an exchange on the air about differing points of view. While this seems to be an uncomfortable moment for the candidate, it ...

Ultra Vires with an Emphasis on the Law in Georgia Research Paper

Ultra Vires with an Emphasis on the Law in Georgia - Research Paper Example Sometimes this term is used to signify the act of directors of a firm in which they exceed the power granted them. The cases of Ultra Vires, which include case of Rayfield v Hands, Ashbury Railway Carriage and Iron Company and Shuttleworth v Cox Brothers and Company drives attention towards the laws regarding ultra vires in many states, including Georgia, along with the conditions which decide whether an act is ultra vires or not. There are many cases registered under ultra vires. One of them is the case of Rayfield v Hands. Field-Davis Ltd. was a firm doing business as constructors. This company followed the Companies Act 1929 and had share capital of 4000 Euros. These 4000 Euros were further divided into shares of one Euro each out of which 2900 were issued (â€Å"DOCTRINE OF ULTRA VIRES-EFFECTS AND EXCEPTIONS"). Leslie Rayfield was the plaintiff (now called claimant) and had 725 shares as a shareholder in the company (â€Å"DOCTRINE OF ULTRA VIRES-EFFECTS AND EXCEPTIONS†). Moreover, Gordon Wyndham Hands, Alfred William Scales and Donald Davies were the defendants as well as the directors of the firm. According to the article 11 of the articles of the association of company, it was necessary that the directors of the company will take the shares at a fair value if the shareholder informs them regarding his transfer of shares in the company. To this, the defendants disagreed to take in and pay the fair price to the plaintiff. The claimant filed a complaint and later it was found that the articles were put together in such a way due to which directors were required to purchase the shares at a fair value (Cassidy, 2008). The objects of Ashbury Railway Carriage and Iron Company written in its Memorandum of Association were to only supply the material necessary for construction of railways and not to work on construction of them. However company entered into the contract of building railways. This was clearly in opposition with the provision of the Company Act of 1862(â€Å"DOCTRINE OF ULTRA VIRES-EFFECTS AND EXCEPTIONS†). Due to this contract, being against the Memorandum of Association was considered as ultra vires and not even the directors of the company could act against it even with their mutual consent. The shareholders could have passed a resolution to sanction the release or they could have changed the terms and conditions that were a part of company’s memorandum or articles. In the case of Shuttleworth v Cox Brothers and Company, it was decided that the contract decided on the basis of the articles present in the memorandum between the firm and the plaintiff could under goes change. If this new change is in the favor of the company then the contract will not be breached and this change will be considered as valid. Due to this, there was no doubt left that the alteration could be beneficial for the firm. Since there was dearth of evidence to prove the act of alteration of bad intentions, hence shareholders coul d not be questioned. Considering all this, the claimant was not granted the relief (â€Å"DOCTRINE OF ULTRA VIRES-EFFECTS AND EXCEPTIONS†). Georgia has its own laws when it comes to ultra vires. Rules and regulations that are posed on the firms working under Georgia’s laws are, 1. A corporation’

Enhancing Competitiveness through Strategic Marketing Term Paper

Enhancing Competitiveness through Strategic Marketing - Term Paper Example In the same vein, the organization will accomplish nothing if it spends less on the marketing of a product that requires more. The specific considerations include the newness or uniqueness of the product. If the product represents a market innovation or it is different from other products available in the target market, such a product has a built-in advantage, according to the so-called Porter generic strategy as posited by market analyst Michael Porter. Central to strategic marketing is the research data on how customers buy, what they buy, where they buy, how they buy. This elaborates the principle of the 4 Ps in marketing which are a product, price, place, and promotion. In the target market, the organization decides if it wants to be the industry leader, follower, challenger or niche-maker. Does it want to dominate this market or simply snag a share in it The scope and coverage of the market strategy depend on these choices based on conditions reflected in the market research? The company also determines if it wants to fast-track its sales effort by using aggressive methods or warfare-based tactics, which refer to defensive or offensive, flanking or guerrilla maneuvers.Before the actual market launch, a company prepares for the big event with its mind already made up on the mix of methods it will use. The marketing, promotion and advertising methods are already specified, along with the product packaging and physical distribution. Cost projections for sales and related activities are in place, while prices have been determined based on the end user's perspective. Also, the company must have determined the appropriate pricing and credit schemes as t o where introductory discounts would be offered. Equally important is the availability of plans to deal with competitors and some fallback measures in case the sales target is not reached.  Ã‚   Cost projections should be developed on the short-term, medium-term and long-term basis and drawn at least one year ahead of the product launch for good measure. This should be updated monthly at first and then quarterly or annually afterward.
