Harrison Ford Essay - 1390 Words
Harrison Ford Harrison Ford was born to the proud parents of Dorothy Nidelman and Christopher Ford on Wednesday, July 13, 1942. His birth came almost six months after their marriage on February 3, 1942. Days later, he was named Harrison Ford in honor of his maternal grandfather. Most of his young life, he preferred that people call him by his grandfathers name, Harry. He had a brother named Terence. Terence and Harrison, or Terry and Harry, as they were better known, grew up in Chicago and attended the Graeme Stewart Elementary School. In grade school, a class mate remembered him as sort of a prankster or a wisecracker. As Harrison grew into a teenager, he had little trouble earning pocket money. He briefly worked on a yacht,â⬠¦show more contentâ⬠¦After one Christmas they collectively owed around $5,000. To pay off their debt, the roommates came up with the idea of creating a humorous magazine. Harry did pen and ink drawings along with many cartoons. Their magazine was called The Mug. They gave advertisers the impression that it was an official publication of the school but it was actually an official publication of Bill and Harry. In his junior year, Harry was cast as Mack the Knife which was the lead in The Threepenny Opera. Although he had tremendous stage fright, he was terrific. In 1963, Harrison Ford began seeing Mary Marquardt, who attended Ripon also. Many people thought they were opposites. She was quiet and plain, and Harrison was usually seen with girls that were prominent on campus and very attractive. Harrison dropped out of Ripon one month before graduation. Harrison and Mary were married in June of 1964. Mary spent the early part of her wedding night watching Harrisons second performance in the production Take Her, Shes Mine. The newlyweds spent their honeymoon settling into the theatrical life together. An experience both seem to relish. Soon Harrison told friends that he was off to Hollywood. Harrison and Mary loaded up their beaten-up Volkswagen bus and hit the road to California. Marys influence was unmistakable in Harrys acting career. She was ever-present, ever-supportive, and she seemed to be the driving force behind the quiet actor.

Defining Magwitch in Great Expectations Essay - 1043 Words
Defining Magwitch in Great Expectations Great Expectations was written in the era of Queen Victoria; ironically a time of great progress and prosperity. Sadly, this was not the case for all. Education benefited the rich. As a result, there was a huge gap between the rich and the poor. The justice system was harsh, favouring the rich, two hundred men and women were put before the judge to be sentenced to death every week. It is clear that Dickens reflects on the society of the time, and shows the unjust, class divided society Magwitch was a part of and the need to reform a legal system which treated this man so unjustly. Knowing Magwitch grew up in this brutal society, it isnt surprising thatâ⬠¦show more contentâ⬠¦There is a sense of gratitude on his part which the reader has to respect. We see this kindness again when Pip goes to the pub with Joe, Mr. Wopsle and a stranger one night. During the course of the evening, the stranger brings a file out of his pocket to stir his drink. The file he uses is identical to the one Pip gave to Magwitch that night on the marshes. Later the stranger gave Pip a shilling rapped in two pound notes. This generosity soon becomes obvious to the reader and that the money is from Magwitch. It is these moments of compassion which alter the readers view of the violent bully and create a sense of respect for him. Magwitch describes his life as in jail and out of jail and in his own words he tells us that he is a criminal, but that he is not ashamed. It is not surprising considering that he was abandoned from an early age and so he was ill brought up and a thieving turnip was the only way for him to stay alive. Jail was his second home and he soon became a juvenile offender in trouble with the police all the time and eventually got the reputation of being hardened. You can hardly be envious of Magwitch life and you begin to pity him.

Essay on A View from a Bridge by Miller Example For Students
Essay on A View from a Bridge by Miller Explain how Miller builds-up and develops the character of Eddies Carbone in the three key scenes from A View from a Bridge A View from the Bridge centres predominantly around a poor Sicilian patriarchal community. The first publication of the play was 1950 in United States. The play was set around 1940-1960 and the setting of the play was in Brooklyn. Their culture entails loyalty and family honour at any cost. Arthur Miller has used these fierce cultural beliefs as an aid to build up dramatic tension, irony, hatred and love through the characters who are supposed to abide by this notion. He also uses characters with strong personalities and potentially dangerous character flaws to create and develop the character. Arthur Millers intentions of writing the play were for it to be a Greek Tragedy. The Greek tragedy shows the downfall of an individual through the capacity and limitations of human life. It is a melodrama because it involves action and improbable events. The play was first presented in a one-act format. This enabled Arthur Miller to make the action continuous drawing attention to the single line of plot which emphasises the inevitability of the ending. It is also like the Greek tragedies because it observes the unities of being a single plot, strong story line, a single setting and a continuous time or a 24 hour time span. To reduce the time span Arthur Miller introduces a chorus which is undoubtedly Alfieri, he is the super-chorus who narrates the play with a habit of hopeless intervention. Arthur Miller describes this play as a tragic betrayal. I also cogitate that Arthur Miller tries to express how someones feeling towards something can be changed by love and jealousy. This is because at the beginning of the play Eddie was degrading a boy named Vinny Bolzano for snitching on his uncle and due his love for Catherine and his jealousy towards Marco and Rodolfo executed something that he clearly was disgraced by. He says Eddie is an incestuous character in the play. He compares the play with Macbeth where again a tragic betrayal takes place. He says love is what fuels the violence in this play. In an interview which took place by BBC he talks about the play . He portrays America as where all the hope was. He states that the play has a history; he establishes that this play is something extraordinary. He personifies the bridge by saying the bridge has its own culture. Eddie Carbone is the main character in the play and every significant act in the play is reflected on him. Eddie is a forty-year-old hard working, Italian-American who is a Sicilian descendant. He is forceful, energetic, obsessive, and overprotective. This is shown when he says Please do me a favour will ya? I want you to be with different kinds of people. I want you to be in a nice office. The repetition of the word want emphasises and portrays his domineering character and over protectiveness towards Catherine. He is capable of self-delusion on a grand scale. Eddie Carbone is an epic character; he makes bold moves and does things that are completely out of the ordinary On the other hand he can also show warmth and generosity. The less you trust, the less youll be sorry. This shows that Eddie doesnt tend to trust can be suspicious about people who seem to be a stranger to him. Eddies obsession towards Catherine becomes uncontrollable and obviously unnatural. He is a man who has few interests outside the family. Eddie: unromantic but considerate, demanding but responsible, scheming but stubborn, brooding but pessimistic, uncompromising but self-interested, irrational but passionate, and love-abiding. Rodolfo and Marco who are two brothers, who came from America as immigrants. Their main aim is to earn because of the difficulties in Italy. They are Beatrices cousins. They both have totally different personalities compared with each other. When Eddie offers to let Rodolfo and Marco stay he conveys the image of himself being very munificent and generous. Here I explain in detail about each of them. .u322f959fcd7c58e5988e407c8cb10cba , .u322f959fcd7c58e5988e407c8cb10cba .postImageUrl , .u322f959fcd7c58e5988e407c8cb10cba .centered-text-area { min-height: 80px; position: relative; } .u322f959fcd7c58e5988e407c8cb10cba , .u322f959fcd7c58e5988e407c8cb10cba:hover , .u322f959fcd7c58e5988e407c8cb10cba:visited , .u322f959fcd7c58e5988e407c8cb10cba:active { border:0!important; } .u322f959fcd7c58e5988e407c8cb10cba .clearfix:after { content: ""; display: table; clear: both; } .u322f959fcd7c58e5988e407c8cb10cba { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u322f959fcd7c58e5988e407c8cb10cba:active , .u322f959fcd7c58e5988e407c8cb10cba:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u322f959fcd7c58e5988e407c8cb10cba .centered-text-area { width: 100%; position: relative ; } .u322f959fcd7c58e5988e407c8cb10cba .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u322f959fcd7c58e5988e407c8cb10cba .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u322f959fcd7c58e5988e407c8cb10cba .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u322f959fcd7c58e5988e407c8cb10cba:hover .ctaButton { background-color: #34495E!important; } .u322f959fcd7c58e5988e407c8cb10cba .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u322f959fcd7c58e5988e407c8cb10cba .u322f959fcd7c58e5988e407c8cb10cba-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u322f959fcd7c58e5988e407c8cb10cba:after { content: ""; display: block; clear: both; } READ: The Handmaids Tale Essay PaperRodolfo is the more spirited and attractive of the two immigrant brothers whose arrivals change Eddie Carbones destiny. It is he who impulsively speaks first in the street, unselfconsciously celebrating the fact of his arrival in America. He is a ready verbaliser, eager to offer vivid little pictures of life in Italy and his ambitions for e. g. where he wants to be a messenger with his motorbike in Italy. When he expresses something stage directions tell us that he tries to precisely explain what hes saying. His short, grammatically simple sentences add to the general impression he creates of ebullient and intelligent oddity. Rodolfo is a character who is very ego but his charm overrules it. He makes jokes and is not afraid to use his own experience as a subject for them. Marco offers an example of what counts manliness. Hes got a lot if masculinity to himself. Marco is a person who tends to have a responsible character. He is obviously devoted to his family and speaks of his wife with deep, if restrained, affection. He is more sensible than Rodolfo, whom he treats with the indulgence of an older, wiser brother. He also is a very responsible and supportive person for his younger brother Rodolfo where he supports him when Eddie tries to mock him. Marco is polite and courteous. He has a strong sense of justice. Marco is the character we know least about throughout the play. Eddie Carbone shows varieties of aggression throughout the play to all the characters. Eddie is a very aggressive where he wants Catherine to finish school he says Youll get no-where unless you finish school. He describes Rodolfo as nice kid or weird. To Marco says It aint so free here either and also says Dont make me do nuttin and he says The truth isnt bad as blood. In all these quotes hes shows a lot of aggression to the surrounding characters especially to Rodolpho and Marco. Eddie is the tragic protagonist, meaning that hes the central character the tragedy falls upon, but also is the tragic hero throughout the whole play. In the opening minutes of the play the main focus is conflict, with the first being between Catherine and Eddie. The conflict is an emotional one about something physical. It is clear at this point that Eddie is fond of Catherine: he refers to her hairstyle being beautiful and this compliment suggests his affection towards her. Eddies more protective nature is revealed when he comments on her short skirt and her high heels, saying, You are walkin wavy! I dont like the looks theyre givin you in the candy. and he also says to Catherine, Where you goin all dressed up And what happened to your hair? soon after he begins to enquire about her skirt when he says, You look like one of them girls that went to college I think its too short. Catherine tries to defend herself, but is reduced to tears when Eddie harshly comments on her. At the very begging of the play it becomes apparent that Eddie cares a lot about Catherine and is very affectionate and caring towards her.

Class Tardiness
Class Tardiness Abstract Class tardiness has remained a perpetual problem throughout the history of learning. Although much literature has been expended over issues of indiscipline within the school system, very little has centered on tardiness mainly evolving around absenteeism, drugs, gang links, gun control and violence.Advertising We will write a custom research paper sample on Class Tardiness specifically for you for only $16.05 $11/page Learn More This study therefore attempts to extend research on class tardiness by discerning the basic questions regarding promptness in school and class attendance by students by initiating a study using 3rd graders at a public school in New Jersey. The methodology applied was action research whereby both students and parents were integrated in the study. The results were quite remarkable revealing a tremendous turnaround of the tardy students becoming punctual after the introduction of a prompter. The study was however limited by tim e constraints and lack of independent validation. Nonetheless, the study was instructive and gave indication that the dilemma regarding tardiness can be fairly lessened if not eradicated. Problem Statement The issue of class lateness or tardiness has remained an unending topic with teachers and administrators perplexed on how to deal with the phenomenon. I thus resolved to investigate the reasons why this problem of tardiness is so persistent. By unraveling these issues, I hope to propose a more lasting solution to this eternal dilemma hence assist all the stakeholders resolve the predicament. Conclusion And Recommendations The general objective of this research is: To determine why students are tardy in school and class attendances. The specific objectives are: To determine the influence of teachers and school administration in students tardiness To examine the role of family or parents influence on the tendency of students to be tardy. Purpose of the Study The purpose of this action research is to establish why tardiness has persisted to be an incessant problem in learning despite various measures taken by school administrators and teachers to curb it. By applying an inclusive action research methodology, the study can determine how to resolve the problem of tardiness thus assist the various stakeholders plagued by undisciplined students.Advertising Looking for research paper on education?

Get your first paper with 15% OFF Learn More Research Questions After careful review of the available literature and the inherent problem, the following two research questions were determined as most relevant to the study. Will the alarm clocks initiative have any effect on classroom attendance? Will seeking the parentsââ¬â¢ assistance in the purchase of the alarm clocks happen as expected? Scope of the Study Class tardiness and absenteeism remain an infinite quandary ever since the start of schooling. Students arriving late in class constantly reveal a lack of personal commitment, inherent domestic problems, or other psychological problems while disrupting lessons for others. The study applies intervention measures that aims at generating reasonable prognosis of how to reduce or eradicate the problem as identified. Literature Review Within our school system, teachers and school administrators have always tackled the issue of class tardiness and absenteeism though the latter has being deemed more urgent due to incidents of drug abuse, gang enrollment and gun violence. Nevertheless, the issue of tardiness continues to plague many schools as school and class attendance rates continue being high in most jurisdictions. Tardy students tend to disrupt the whole class thus also affecting the grades of punctual students. This is particularly significant since interruptions are at the beginning of the lessons when as Wong (2004) explains is the most crucial time for students to disseminate lessons . Slavin (2003) consequently emphasizes the importance of teachers setting the tone for lessons during the start of the lesson. Most analysts therefore agree that tardiness is great disrupter of learning and is the precursor for future tardy behavior for the culprits (Eggen and Kauchak, 2005), (Wong, 2004), (Wolfgang, 2001), (McKeachie and Svinicki, 2005). A study by MacNeil and Prater (2001) revealed that, ââ¬Å"both principals and teachers viewed absenteeism and tardiness as their most serious problemsâ⬠(p. 5). The authors thus proposed for all stakeholders to take a more proactive role in enforcing discipline within schools in view of the escalating problem. Being punctual is not only an obligation for students, but also a part of personal etiquette, reverence, character, significance, and valuable while tardiness reveals a lack of dedication by the student to learning.Advertising We will write a custom research paper sample on Class Tardiness specifically for you for only $16.05 $11/page Learn More With class tardiness becoming a habit rather than an exception, Wolfgang (2001) has asserted that the onus is on teachers to instill discipline in class that can greatly reduce issues of tardy students. However, Wong (2004) has a different view arguing that cases of tardy students should be left to natural ending whereby the students will be forced by circumstances to change their attitude for the better. Wong thus insist grades should not be used as a deterrent but rather other approaches like awarding certificates with students being made aware of the import of punctuality and potential rewards rather than the negativity aspects. Eggen and Kauchak (2001) are also against extreme severe punishments for tardiness since some students are sometimes quite ignorant of their actions. However, they assert discipline must be upheld and the intervention timely and consistent to make the student aware of the need to be punctual. Lack of p roper class management can lead to severe state of tardiness becoming the norm rather the exception. Wong (2004) who reemphasize the critical years of adolescence when the childââ¬â¢s future is molded to be vital for all time supports this argument. Eggen and Kauchak (2001) have also emphasized the need for teachers to be effective role models for the students, as incidences of their own tardiness will be generally mirrored by the children. Dai and Sternberg (2004) have reiterated the need to motivate students to shun being tardy. Charles (2005) advocates for evoking ââ¬Å"curiosity as the greatest motivator for learningâ⬠(p. 103). This makes learning exciting by means of diversity and freshness in the lessons in class . Students can be motivated to compete against other classes and with each other as an impetus to advance their class attendance and boost grades. Slavin (2003) thus agrees that exiting classrooms can be tremendous motivators for students who will be eager t o get the next lesson hence will be always punctual.Advertising Looking for research paper on education? Let's see if we can help you! Get your first paper with 15% OFF Learn More Methodology The design of this study was classroom action research. Hendricks (2009) defines this type of action research as that used by teachers within their classrooms for the proposed express purpose of enhancing performance. Through the action research process, ideas gained from the study can be shared with colleagues. The research centered on the three classes of 3rd graders in the school which the researcher labeled as Class X, Y, and Z to avoid bias and hence create anonymity. Limitations of the Study The researcher was limited by the lack of control of the main instrument for the survey, the alarm clock that was to be operated by the subject students hence offering instances of neglect or ignorance. The study was also dependent on the cooperation of the parents and fellow teachers thus leaving the researcher reliant on their expediency. Lastly, time constraints limited the research in generating sufficient ground for a conclusive hypothesis.

Wildlife Management and Animal Rights Essay Example | Topics and Well Written Essays - 250 words
Wildlife Management and Animal Rights - Essay Example They refer to such usage as exploitation. Such information is misleading and not worth following. Animals are there for easing human efforts and utilization daily life. It would, therefore, trigger some king of primitive report to commence comparing animals at the level of human beings. Even the domestic animals are on the inclusion in the table. They are critical in the provision of basic human wants such as milk and meat, hence improving the global economic aspects. A third of the global population has dependence on the animals for their live food and survival. It would be understatement to call upon the government wildlife department to call it official that all the domestic animals ought to be treated as human beings (Wywialowski, 1991). Animalââ¬â¢s rights and welfare should only rotate around ensuring that the animal has good shelter, enough food, and is not overworked. In essence, these are the triad consisting of the best animal care and welfare. Any other form is a gross obsession, and the wildlife managers ought to put that in consideration to avoid immense conflicts that occur between them and the animal rights activists. Wywialowski, A. P. (1991). Implications of the Animal Rights Movement for Wildlife Damage Management. Great Plains Wildlife Damage Control Workshop Proceedings, paper 7.

Disability Definitions Analysis Research Paper Example | Topics and Well Written Essays - 750 words
Disability Definitions Analysis - Research Paper Example IDEA defines what these disabilities are, and who is eligible to receive education based on their unique needs. This paper will look into some of the descriptions of the disabilities under the IDEA, and what characteristics and features are in place to identify these individual needs. Learning disability: Under the IDEA, this is a disorder where normal psychological processes involved in the using of language, or understanding are able to manifest in a manner that fosters an imperfect inability to either think or listen. In the IDEA definition, there is the inclusion of conditions that count as learning disabilities. These include: brain injury the student may have, brain dysfunction, dyslexia (reading disability), and/or perceptual disabilities (Kaufman & Kaufman, 2001). However, learning difficulties, for example, emotional disturbance and economic disadvantages, do not fall under this definition. Mental retardation: Under IDEA, this is the lack of cognitive abilities. This means that these individuals face limitations when it comes to social skills, taking care of themselves, and issues with communication. Students with mental retardation are typically slower than the rest of the students. These cognitive disabilities render the student much slower when it comes to speech. They also have problems taking care of their personal needs while in school (Burns, 2006). Emotional behavioural disturbance: Under the IDEAââ¬â¢s definition, it is a condition that renders a child with sub average intellectual functioning. This is a disability that cannot be explained by health or intellectual factors. The presence of some factors over a long period might indicate that a student is incapable of maintaining a steady educational environment. Deficits in adaptive behaviour, according to the act, affect the child, hence affecting their educational environment (Mastropieri & Scruggs, 2007). In learning disabilities, there are no factors that affect the student from the

Health Care Access - Research Paper Example And the people can simply chide him eventually in order to change his mind. Facts should clarify the right decision that should be made. Because the fear and argument generated by the good governor was about heavy indebtedness and loss of sovereignty, this paper endeavoured to check on the validity behind his reasoning against supporting the Obama Health Care plan to improve Medicaid and to insure the public with health care insurance. Random sampling of empirical data was done to find out what is meant by the possibility of losing sovereignty. Findings reveal that the total debts of USA are below the average in terms of percentage growth of total debts of the world since 2001. Compared to nine (9) out of eleven (11) countries included in the random sample, it shows that annual increases in US debts are normal. Details are shown in Table 1. The total debt statistics of ten other countries ââ¬â UK, France, Japan, China, Canada, Israel, India, Russia, Germany, and Saudi Arabia ââ¬â were chosen at random for comparison with the USAââ¬â¢s debts.

Introduction To Strategic Management Business Essay
Introduction To Strategic Management Business Essay Alfred D. Chandler, an American business historian, defined strategy as follows: Strategy is the determination of the basic long-term goals and objectives of an enterprise, and the adoption of courses of action and the allocation of resources necessary for carrying out those goals. Here A. Chandler believes that strategy consists of equal importance to defining objectives and goals as it is to providing the measures for attaining them. Strategic management is a consistent level of managerial activity of setting up goals and tactics and ensures a variety of decisions by the top management to successfully achieve those aims or goals in the long term and at the same time providing for adaptive responses in the short term. This provides an overall direction to an organization. The strategic management process consists of three components: Strategic analysis, strategic choices and strategic implementation. These components are vital in a firm as it appraises the business and industries in which the firm is a part of. It also brings about a healthy competition and helps in defining of attainable goals in present and future and also reevaluates each strategy. The Components Of Strategic Management Process, in its plainest sense, is fixing tactical decisions, evaluatin g the strength and recognizing the critical external factors, which may play a part in influencing the position of the firm and also defining the factors that bring about the implementation of a firm through these components. Different from the classic business planning, Strategic management focus involves Mission, Vision and Out-of-the -box thinking. Top management uses strategic management to describe where and when they would want to position their firm in the industry. Strategic planning helps assess the firms opportunities and threats, exposes its strengths and weaknesses as well as encourages the firm to adapt. A SWOT analysis, strengths, weakness, opportunities and threats, is an excellent way to help develop a strategic plan. Like used by many Fortune 500 companies, these four components pose as the building blocks of a strategic plan for a firms existence. Similarly, PEST analysis (Political, Environmental, Social and Demographic and Technological factors) is a examination of the external marco-enviormental in which in firm exist. It helps to examine the effect of these influences on the firm as opportunity and threat in the SWOT analysis. It is also used for assessing the market rise and fall, and as such the position, potential and direction of the firm. The BCG (Boston Consulting Group) Matrix is a four-celled matrix; it is the most renowned strategic planning tool. It provides a graphical representation for the firm to examine diverse companies in its portfolio. It provides the management with a comparative analysis of firms potential and the evaluation of environment, which it operates in. Organization Structure Organization is a term that can be studied as a process as well as a structure. In a fixed sense, organization is a structure, where a team of people functions and tries to accomplish a certain objective. In the words of Kast and Rosenzweig, structure is the established pattern of relationships among the component parts of the organization. In this sense, the network of relationships among individuals and positions in the firm are refers to as an organizational structure. Organizational structure defines how responsibility, roles and power are coordinated, controlled, how information moves between the different stages of management and how they are assigned. When the most of the decision making power and control over departments and division lie with the top level management it is know as Centralized structure. In a decentralized structure, the decision making power is distributed over the departments and allowing them to enjoy certain degrees of freedom. There are four major components that affect organizational structures, they are, Environment, Strategy, Technology and Human Resource. Environment being are very volatile factor itself, managers will face more problems depending on how fast it changes. Thus, structures need to be more flexible in order to face these changes; this would also suggest the need to decentralize authority. Various strategies would need to utilize different structures. Such as a differentiation strategy would require a flex ible structure and low cost would need a more formal one. Organization structures are also determined by what type of technology is being used. For instance, a company that has an automated operational system would opt for a decentralized structure because the progress of employees would be monitored and the immediate supervisor would be able to provide guidance and when needed. One of the most commonly found structures found within firms is the functional structure, it consist of small units or departments which are grouped or identified by specialty, like finance, IT, logistics, sales, human resource, and so on. This distinguishes the departments by product produce by each unit or geographical region; this enables managers to maintain more control over each group. This structure is based on high specialization and high control and efficiency concept. In terms of effectiveness, the functional structure is most effective in small to medium size firms that only deal with a few produc t and services. A matrix structure is an organizational reporting structure frequently used for project-based teams. This structure uses both departments as well as products as determinates to group teams together; this allows ideas to flow between various parts of the organization. This is a complex structure of reporting relationships and has proven to be very flexible and can respond rapidly to change. It is effective for a large organization with a large number of products and services. Strategic Mapping A strategic group is a concept used in strategic management where companies that are a part of the same industry and provide similar business models and/or similar strategies are grouped together. For instance, the fast food industry can be divided into different fast food joints in terms of pizza or burgers, which can be based on different variables like time, price, presentation, etc. The number and the composition of the groups within the industry depend on the dimensions used to define them. Strategic management experts mainly use two-dimensional grid in order to justify their direct competitors, those with similar strategic models, and their indirect rivals. M. Hunt (1972) devised the term Strategic Group whist analyzing the appliance industry after discovering the high level of competitive rivalry. He the then subscribed this to the subgroups existing the industry. This then caused the industry to undergo rapid innovation, price reduction, increase in quality and lower profitab ility than normal economic models would deliver. M. Porter (1980) developed the concept and explained strategic groups in terms of Mobility Barriers. Value Chain Analysis This analysis focuses on every level of the business that it goes through from raw materials to the final user. The goal is to maximize value at the least possible cost. For one to better understand the activities from which an organization creates shareholder value and competitive advantage, it has been proven useful to simplify the business system into series of value-generated activities, also known as value chain. Michael Porter, in his book Competitive advantage (1985), introduced a value chain model that consists of arrange of activities that was found to be common to a wide range of firms. M. Porter identified these activities and classified them into primary and support activities. The primary activities include Service, Marketing Sales, Operations, Inbound and Outbound Logistics. Theses activities are supported by four components Infrastructure of the firm, Human Resource Management, Procurement and Technology Development. The main goal of the value chain analysis is these activities need to provide a higher level of customer satisfaction that exceeds the cost of them, thus creating profit margin. In other words, the firms margin depends on how effective the firm is on performing these activities efficiently, so that the level of customer satisfaction is sufficient enough for them to pay for the products that exceed the cost of the activity itself. By reconfiguring the value chain a firm may be able to achieve a competitive advantage by providing better differentiation or through lower costs. Value chain activities are not inaccessible from one another but rather one activity often affects the cost or the performance of the other. There may exist linkage between primary activities or between primary and support activities. The value chain analysis is a flexible tool for a firm; its competitors and the industry. It can be used to create or study the competitive advantage on both cost and differentiation. Cost advantage is done through a better understanding and squeezing out the cost from value adding activities and differentiation is achieved by focusing over those activities with core capabilities in order to out pre form the competitors. It provides a deeper understanding of the firms strengthens and weaknesses. The main advantage of value chain is that it is adaptable to any type of business, big or small. However, M. Porters book Competitive Advantage, the value chain is largely focused on manufacturing industry, thus puts off other types of business. Due to the complexity of the value chain analysis and the scope and scale of the value chain has proven to be intimidating, it is time consuming. To understand the firm competitors one must identify and examine the key differences and strategy drivers, hence, needing substantial information. The business information system is not always structured to draw out information easily for a value chain analysis.

The Impressionist Movement :: essays research papers fc
à à à à à Impressionism was a movement that occurred in both art and poetry. It was a time in which the people broke from the traditional standards or styles. They wanted to bring new ways of expressing their ideas to their societies. These ideas were seen through subjects of interest, such as art and poetry. Claude Monetââ¬â¢s Woman with a Parasol: Madame Monet and Her Son and William Butler Yeatsââ¬â¢s ââ¬Å"The Wild Swans at Cooleâ⬠both characterize important aspects of the Impressionist Age. à à à à à The word ââ¬Å"impressionismâ⬠is mostly associated with the artistic movement. The first time this term was used with reference to art was when one writer was speaking of a painting by Claude Monet, called Impression: Sunrise (1872, Musee Marmottan, Paris). The term was first officially used in 1877 (ââ¬Å"Impressionismâ⬠). The artists of this movement were characterized as impressionists because of their simplified works (ââ¬Å"Monet, Claude Oscarâ⬠). They were part of a group in which the artists shared similar styles and techniques between 1867 and 1886. Some of the important artists were Monet, Renoir, Pisarro, Sisley, Morisot, as well as a few others (Pioch). Monet and Renoir both painted scenes of La Grenouillere. Their work signified the beginning of this new age of art (Mataev). The Impressionist Movement grew because these painters wanted a different style, a new technique, and paintings with more unique subjects. The popular paintings of the time were all approved by the Academie des Beaux Arts. The standard type of paintings that were most commonly approved included a scale of tones for forming shapes and blacks and browns for making shadows. These classical paintings were realistic, usually of scenes indoors. Impressionists turned from this traditional art and began to paint their subjects outside, using unarranged light. These paintings were more spur-of-the-moment type, and appeared less realistically (ââ¬Å"Impressionismâ⬠). There are certain characteristics that set impressionist art apart from all other styles of art. à à à à à Impressionists, both in art and poetry, portrayed great images of their subjects by using their styles or techniques. They often captured scenes with vivid color, with great light effects, and with motion (Sporre 525). The impressionist painters tried to view their subjects not as what they really were, but as different areas of color, shapes and light. They commonly used quick, free brush strokes of non-detailed spots of color. This method created a lively appearance (Sporre 527). Impressionists did not mix their colors, as the earlier artists had done.

ââ¬ÅEleanor Rigbyââ¬Â by The Beatles Essay
ââ¬Å"Eleanor Rigbyâ⬠is an original song written by John Lennon and Paul McCartney of the one of the most famous bands of all time, the Beatles. The song was about the indistinct story of a woman named Eleanor Rigby who lived a heartrending and desolate life. The still and hollow life of Eleanor Rigby seemed to have followed her after her death as the song depicts the absence of people ââ¬â neither her family nor friends ââ¬â during Eleanorââ¬â¢s funeral. Lennon and McCartney wrote, ââ¬Å"Eleanor Rigby died in the church, and was buried along with her name, nobody came. â⬠This particular line suggests the silent passing of Eleanor Rigby ââ¬â that is, as if she never existed when she was still alive, and when she died, her name got lost in the sea of people who were born and have died without leaving any sign of their existence. In general, Eleanor Rigby represents all the lonely people in the world who suffer the same emptiness and insignificance. Considering the structure and the content of the song ââ¬Å"Eleanor Rigby,â⬠it may be classified as a ballad for various reasons. The defined characteristics of a ballad fit the structure and content of the song. For one, the song tells a story (ââ¬Å"Characteristics of a Balladâ⬠), although indistinct, about the unpretentious life of Eleanor Rigby and the involvement of Father McKenzie in her interment. The indistinctiveness of Eleanor Rigbyââ¬â¢s story entails the reading between the lines and the direct interpretation and assumption of her life and how Lennon and McCartney related it to the sea of lonely faces that live and die not knowing who they are, what theyââ¬â¢re supposed to do, and such. Second, the story of Eleanor Rigby is told through simple, uncomplicated language (ââ¬Å"The Ballad). One can easily deduce what her life was all about, although the meaning necessitates a deeper look and understanding, the main idea of the song is clearly understood from the lyrics. Other features of the song that match its categorization as a ballad includes its dramatic and somber tone, the direction of the first few lines of the song which directly takes the reader or the listener toward cataclysm, and the focus of the song which is on a particular situation or experience. (ââ¬Å"Characteristics of a Balladâ⬠) The feeling of loneliness and sadness is felt throughout the song, from the first line to its last. The repetitive tone of being abandoned and deserted is reflected leaving behind a depressive and sad state of mind. (Price) Next, the first line, ââ¬Å"Ah, look at all the lonely people,â⬠smashes directly into the catastrophic or tragic motif of the song ââ¬â that is the lonely life of Eleanor Rigby, and her seeming demise even before her actual bereavement. The focus of the song is on her life and how it relates to other lives that are plagued by uselessness and non-existence. The more specific features of the song that are readily observable, depicting its inclination to become categorized as a ballad, has something to do with the repetition of the lines throughout the song (ââ¬Å"The Balladâ⬠), particularly the following lines: ââ¬Å"all the lonely people, where do they all come from, all the lonely people, where do they belong. â⬠In addition, the song was written on a third-person perspective, such that the author does not interfere with the events in the story constituting the song. The life of Eleanor Rigby was narrated in such a way that the author is identified as an observer or spectator.

From the narrative tone of the song, to the uncomplicated or simple use of language in depicting the story, from the dramatic tone of voice, to the direct theme of catastrophe and tragedy, the repetition of various lines, the third-person perspective, and the single focus of the song, which is on the life of Eleanor Rigby and every other individual she represents, everything comes together to form a lyrical ballad which is meant to be sang revealing various emotions of clarity. s Works Cited ââ¬Å"The Ballad. â⬠(N.

Garry Glowacki essays
Garry Glowacki essays Garry Glowacki: A Representative for Justice Alternatives to Prison Garry Glowacki was nice enough to come and speak about his job in the law enforcement field. The field stretches out so far that some parts you wouldnt even know existed. One of these jobs is Garry Glowackis job. He works in the alternative to prison section of the criminal justice system. Through Garrys Life and work experience he believes that this system really does work. Garry came in and told us what the alternative to justice route of law enforcement is and how it works, but he did not talk about the actual rehabilitation process for it that prison had. Alternatives to justice are part of the criminal justice system in Kingston Penitentiary. The Alternative Justice system works with all kinds of offenders that can be considered not a threat to society when they are held under supervision. As an example, if a man broke into a home and stole another mans television and got caught there are two ways of going about his punishment; the justice system could end up spending over 25,000 dollars on the persecution and jail time of the offender or the offender could be supervised and work off the damages done to the home of the owner by mowing his lawn and trimming the hedges and stuff like that. This alternative will make the prisoner realize that it is an actual person that he has stolen from and realize how hard they worked to get that VCR (or whatever they stole). Garry firmly believed that no one is a bad person; they were just lead in the wrong direction as a child. He Quoted, hurt people, hurt people, and this statement is very true. Generally speaking, offenders have been offended in their lives and that has built up an aggression that they can not deal with. Garry explained that forgiveness is the key. Not forgiveness for their crimes but, actually reaching into the person and finding out what was bothering them in t...

America and The Grapes Of Wrath Essays
America and The Grapes Of Wrath Essays America and The Grapes Of Wrath Essay America and The Grapes Of Wrath Essay Essay Topic: The Grapes Of Wrath In The Grapes of Wrath by John Steinbeck, the time period is set during the Dust Bowl and the Great Depression around the 1930s. Both of these devastations occurred relatively around the same time creating many problems across America. In the Great Plains region, the Dust Bowl hit forcing families into havoc. When families transitioned from their farming lands to industrial factories they were hit with the Great Depression. This affected about 15 million people throughout America. The Dust Bowl surrounded Oklahoma, Texas, Kansas, Colorado, and New Mexico. With almost no rainfall, loose soil, and high winds all of these factors combined to create dense dust clouds called ââ¬Å"black blizzardsâ⬠. From 1934 to 1937, the soil lacked the strong root system to resist the winds. The recurring storms strangled cows and pasture lands moving 60% of the population from the region. Most of these people moved to the west towards cities. The federal government mobilized several new agencies, principally the Soil Conservation Service formed in 1935, to promote farm rehabilitation. Farmers were instructed to plant trees and grass to anchor the soil, to plow and terrace in contour patterns to hold rainwater, and to allow portions of farmland to lie unplanted each year so the soil could restore. 11.3 million acres of land were purchased to keep out of production and by 1941 much of the land was rehabilitated. The region repeated its mistakes during World War II as farmer s again plowed up grassland to plant wheat when grain prices rose. Drought threatened another disaster in the 1950s, prompting Congress to subsidize farmers in restoring millions of acres of wheat back to grassland. The Great Depression was the longest lasting economic downturn in history. After the stock market crashed in October 1929, Wall Street wiped out millions of investors in a panic.Steep declines in industrial output and rising levels of unemployment as failing companies laid o

Dating and Mating Relationship from Christian Standpoint Essay
Dating and Mating Relationship from Christian Standpoint - Essay Example The procedures taken by the current generation have left them with bewilderment, pain, and sexual sin that they have had to encounter in spite of their best objectives. Reasons for such occurrences are pointed out in the subsequent body text. The amalgamation of sex organs for two persons that are sexually active for insemination purpose is referred to as copulation. The process consequently results in an internal fertilization process. In the contemporary world, men and women engage in a process of looking out for spouses with the aim of getting into marriage (Burton, 2010). However, the process raises numerous questions. The Christian religion professes that selection of a companion according to the Bible teachings should assist in securing an individual a perfect match for his or her values. Even though the terms dating and mating are not found in the Bible, Christians are presented with some guiding principles that they should adhere to prior to getting married. Whenever an individual is strongly committed in a relationship, be it mating and dating relationship, he or she should endeavor to acknowledge the Lord. In addition, individuals should adore and respect each other just in a similar manner they do to themselves. The condition is certainly spot on for a dating or mating relationship. Biblical principles present a perfect way of having a secure basis for a dating or mating relationship

Group Signature Essay Example for Free
Group Signature Essay Group signature schemes allow a member of group to sign a message on behalf of the group anonymously and in unlinkable passion. However, a designated group manager can easily identify the signer. The signer of a valid group signature is needed to be a member of the group. These features are important in some specialized applications. This scheme is to be used in electronic business transaction. The scheme needed to satisfy six properties to be secured. These are unforgeability, anonymity, unlinkability, no framing, traceability and coalition-resistant. Mathematicians and computer scientist continues their studies to improve their proposed schemes. It is to satisfy the six properties with no doubt. Key words: group signature, unforgeability, unlinkability, no framing, traceability, coalition-resistant Group Signature Introduction The process, in which certain anonymity is needed to perform a task in spite of a collection of people or groups, is the based the concept of group signatures is born. Chaum and van Heyst first introduced this. The concept of group signature provides a member of group to sign certain messages anonymously and unlinkably on behalf of the whole group. On the other hand, a designated group manager has power to unveil the identity of the signer in cases of dispute. A group signature is verified through a series of algorithm to ensure that the signer is a member of that certain group. However, the groupââ¬â¢s structure is still concealed and the signer can only be identified if the necessity occurs. With this features, the group signature scheme have potential application. Such applications are needed in electronic transaction that needed to be signed. The anonymity of the signer is essential to prevent others to see organizational structure of the signatory group. A group signature is needed to be secured to preserve the unlinkability and anonymity. A group signature scheme must satisfy the six properties. One is unforgeability. This is the property which ensures that only members of the group can sign on behalf of the group. This feature is necessary to make sure that invalid members or revoked members cannot sign on behalf of the group. This provides a way on which if there is dispute in a valid group signature, the group manager can easily find out who the signer is or it can be concluded that it is a member of the group when the message is signed. Number two is anonymity. This feature assures the members of the group that the identification of the signer will be hard except to the group manger. This is one of the main features of group signature. It conceals the identity of the signer. Consequently, it conceals the organizational structure of the group. The third one is unlinkability. This is feature which tells that determining whether two valid signatures were generated by a common member will be hard. This feature is necessary to go with anonymity of the signer. Since if you can identify two valid signatures coming from single member then it will easy to identify the signer. Number four is no framing. This is ensures that no member or the group manager can sign on behalf of other members. This is necessary to protect any member from a wrong identification when a dispute occurs. The fifth one is traceability. The traceability means that a group manager will be able to open a valid signature and determine the identity of member who signed it. It means that in a dispute, the group manager can easily identify the signer. Additionally, this property does not the possibility of not identifying the signer. The last one is coalition-resistant. This means a subset of members of the group or even the whole group cannot generate a valid signature on which the group manger cannot link on one of the members of the subset group. This ensures that a certain valid group signature can always be associated with a single member of the group not with subset of the group. There are many studies which ensure that the six properties are satisfied. There are many proposals of which contains algorithm that is claimed to satisfy the six properties. There are some summaries of articles of proposals and advancement in group signature. The reader would find these summaries of articles to contain dispute of other schemes. Security Remarks on a Group Signature Scheme with Member Deletion The Kim-Lim-Lee group signature scheme is scheme which claims to have a member deletion function, security and unlinkability. These claims are put into consideration because it is found to be unsecured and linkable. This will present some remarks which will prove the unsecurity and linkability of the Kim-Lim-Lee group signature scheme (Wang et al. , n. d. ). This scheme consists of different stages. These are system set up, join, delete, sign verify and open phases (Wang et al. , n. d. ). The system set-up is done by the membership manager in which he sets parameters and compute for secret and public keys. At the same time, the revocation manager selects his secret key and then computes and publishes his own public key (Wang et al. , n. d. ). At the join stage, the user who wants to join the group need undergo an interactive protocol on which he is assigned to a generated membership key and given the public key. Additionally, current members of the group update their membership key (Wang et al. , n. d. ). The deletion stage happens when a member is voluntary or involuntary leaving the group. The membership manger performs a series of algorithm and updates the groupââ¬â¢s public key. He then computes fro the renewal public key. Here, the membership manager publishes the two new public keys. Then, every valid members of the group updates his secret property key (Wang et al. , n. d. ). In the sign stage, a member needed to sign some message. The member submits his membership key and his secret to generate the group signature (Wang et al. , n. d. ). The group signature generated in the sign stage is then subjected to verification. The verifier then uses a series of computation to verify the signature. The verification will yield a result which indicates if a valid member of the group signed it or not (Wang et al. , n. d. ). In the case of dispute, the open protocol is done. The open protocol is done to trace the identity of the signer. Only the group manager can do this (Wang et al. , n. d. ). The process of which the Kim-Lim-Lee group signature scheme under is found to be unsecured. This is due to proven accounts its security parameters is lacking in some cases. It is proven the two parameters used in the scheme are not sufficient to ensure absolute security (Wang et al. , n. d. ). The unlinkability claim of this scheme is also taken to account. The unlikability claim was proven wrong. The group signature scheme of Kim, Lim and Lee is prove to be linkable. It is proven that it easy to associate a given group signature to member of a group. This is due to invariance in the group signatures within time and even in all time periods. It means two signatures can be traced back to signer simple computational analysis (Wang et al. , n. d. ). A member deletion stage is then scrutinized by disproving the claim of which a deleted member cannot generate a valid group signature. The problem with this is identified in the process of the updating the members secret key. It is said a deleted member can simply update his secret along with other valid members since he can compute for a member secret in a given time. At the same time, a new member can get a version of his secret membership in the past time when is not yet a member (Wang et al. , n. d. ). Thus, the security of the Kim-Lim-Lee group signature scheme is proven to unreliable and unsecured. It is needed to revised and improved to satisfy the needs for a good group signature scheme (Wang et al. , n. d. ). An Efficient ID-Based Group Signature Scheme The ID-based signature scheme is proposed to be more efficient than other predecessors. The scheme is based on the process of the ID-based electronic signature. The identity-based signature uses publicly known identifier such as IP address, e-mail address and other identifiers. It is use to compute for public key component of the pair use for digital signatures, encryptions, and key agreement. The private key is computed by a trusted authority. This scheme is aimed to have better efficiency and to cope with large number of members in a group (Popescu, 2000, 29-35). The identity based signature scheme is done in several phases. The set-up process is done by the trusted authority which leads to the extract phase in which the user provide the ID. The ID becomes the public key and the trusted authority returns a private key which is needed to make for the signing protocol (Popescu, 2000, 29-35). The verification of an identity based signature is done by inputting the message with the signature, the parameters and a public key ID. The verify stage outputs the validity of the signature (Popescu, 2000, 29-35). There is another type of ID-based signature which is from the pairings on elliptical curves. This scheme is done to improve the efficiency of the ID-based signature processes. It is basically similar with the conventional one. However, the computations are different and more appropriate for large number of users (Popescu, 2000, 29-35). The scheme use in ID-based signature is put into the context of group signatures. The set-up procedures are similar with the ID-base signature but the group public key and the secret key is computed differently. Compared to other group signature schemes the set-up stage is done more efficiently (Popescu, 2000, 29-35). In the join stage, the user sends the ID to the group manager and the group manager computes for the membership certificate and secretly sends it to the new member in a secure private channel. This process is more efficient since the stages were reduced. However, the security is still intact because of the process in the set-up stage that lessens the work at other stages (Popescu, 2000, 29-35). The signing stage makes use of the public and private key pair which was generated by the user himself. The pair key is use to compute and generate the group signature. It is combined with a random number for it to be anonymous and unlinkable (Popescu, 2000, 29-35). The verify stage is split in the two parts. The first part is that it verifies if the signer is definitely a member of the group. If the signature generated by the group is valid and it is signed by a member of the group, the second stage commences. It is to verify that a member signed the group signature and not the group manager (Popescu, 2000, 29-35). The open stage is done when there is time that the signer needed to be identified. Like other schemes, the group manager can only do this. This process is very easy for the group manager since the manager knows the identity of the user who is associated with the group signature. This is because in the join stage the bind between the user and the manager was forged (Popescu, 2000, 29-35). The ID-based group signature scheme keeps the security properties of a good group signature in tact. The identity based signature guarantees some the properties and the added processes in the group signature scheme made other necessary security measures (Popescu, 2000, 29-35). The ID-based group signature from elliptic curves was derived from the identity based signature scheme. This scheme can handle a large number of members in a group without compromising the security and the efficiency of the process involved. However, the disadvantage is that the efficiency of the group signature is based on the efficiency of the identity based signature scheme it uses (Popescu, 2000, 29-35). Practical and Provably Secure Coalition-Resistant Group Signature Scheme Group signature concept is dual to the identity escrow which this scheme uses to create a coalition-resistant group signature scheme. The identity escrow can replace the membership certificate which other group signature uses. The use of identity escrow in group signatures can be regarded as group-identification scheme with revocable anonymity. This is scheme is just the second coalition-resistant group signature scheme which is an improve version of the first (Ateniese et al. , 2000, 255-270). This group signature scheme differs to other scheme in the efficiency of the join process. The user needs not to send his secret to the group manager not like other conventional schemes. The feature of which the user sends secrets to the group manager is found to be susceptible to attacks. This scheme eliminates such possibility and is proven to be coalition resistant even against adaptive adversaries (Ateniese et al. , 2000, 255-270). The model use by this scheme is somewhat similar to conventional group signature schemes. The group signature scheme undergoes several phases. These phases are the setup, join, sign, verify and in some cases open. Like the other group signature schemes every phase has algorithm need to be follow to ensure the properties to be intact (Ateniese et al. , 2000, 255-270). They only differ in the sign process as this scheme provides an interactive process between the signer and the verifier. The process is derived by replacing the call of the user to the hash function to the call to the verifier. The interactive protocol between the user and the verifier gives way to a more secure group signature (Ateniese et al. , 2000, 255-270). This scheme was proposed to have two major advantages over other conventional group signature schemes. One is the join process is more efficient than other scheme. This is since the new member just needed to provide proofs of knowledge of discrete logarithms in contrast with other schemes which requires new members to prove that a number is a product of two primes. The other advantage is that join process is more secure since it does not require the new member to send his membership secrets which is required in other schemes. Additionally, the property of being coalition resistant against adaptive is in fact an extra advantage (Ateniese et al. , 2000, 255-270). Generally, this scheme surpasses all other schemes created before it in terms of performance and security and it is proven to be coalition-resistant. It is because of the feature like spliting the group manager in two, a membership manager and a revocation manager (Ateniese et al. , 2000, 255-270). Group Signature Scheme with Revocation A number of group signature schemes had been proposed. However, these schemes donââ¬â¢t consider a growing membership or shrinking membership as well. In the real world, a member of a group can join, voluntary or be expelled from the group in any time. This done by other proposed schemes by not issuing changes to public keys and re-issuing group memberships. Thus, Popescu, Noje, Bede and Mang from the University of Oradea proposed a group signature scheme with revocation (Popescu et al. , 2003). There are other several group signature schemes that were proposed. However, these other proposed schemes lacked in efficiency and other others in security. There is a scheme which was proved to be efficient and secured but it requires time periods which any and all verifiers must know, thus requires more time in the verification stage (Popescu et al. , 2003). They proposed a group signature scheme in which every step or phase is different from other group signature schemes. It consists of different computational procedures (Popescu et al. , 2003). In the setup procedure, the group manager needs to undergo several steps which will yield the public key P, the secret key S and a group membership certificate consisting of two integers X and ? satisfying a certain equation which relates the two integers (Popescu et al. , 2003). In the join stage, a user wants to join a group. The scheme requires a secure and private communication between the group manager and the user to protect the anonymity of the user. The user chooses an element from a set formed by the parameters set by the group manager. From the chosen element the user will compute and send an ID which he needs to prove before he chooses a random number from a designated set. The group and the user computes and send computation results to each other until the user received his membership certificate. After this process, only the user knows his membership certificate and that the group manager only registers the ID of the user in the data base which was obtained in the first computation (Popescu et al. , 2003). The user is then allowed to sign to represent the whole group. At the signing process, the user can create a group signature inside a message by computation. The computation starts with the computation with his membership certificate. The user is the only one who knows his membership certificate so he remains anonymous to others. The group signature is then sent to the verifier for verification (Popescu et al. , 2003). In the verification phase, the resulting signature inside a message is verified through a series of computations in which the check the proof of equality between the double discrete logarithm of F (a part of the signature) and the discrete logarithm of Dââ¬â¢s representation base on the element of the set that the group manager defined in the setup process. If it is equal the verifier concludes that the user who signed the group signature is a member of the group (Popescu et al. , 2003). When the time comes when it is needed to know who signs the message containing the group signature. He can do this by checking the correctness of the group signature. If it is incorrect, the group managers abort the process. Other wise, the group manager recovers a certain ID in the database and prove that the ID is relative to the D (a part of the group signature) (Popescu et al. , 2003). When a member of the leaves the group the group performs a series of algorithm which will result to the publication of the revocation status of a user in the Certificate Revocation List which was assumed to be available at all times in a well-known public servers. The CRL is also assumed to be signed by the issuer, the group manager or other trusted party (Popescu et al. , 2003). In this scheme, there are strong considerations in the security as provided different calculations that ensure the impossibility of some scenarios that compromises the anonymity of the members of the group. Furthermore, the cost of the revoke process is linear to the number of revoked members. Additionally, this scheme provides fixed signature size and constant work of the signers which makes it more practical than other group signature schemes. However, the opening process of this scheme can result to hundred of exponentiations per signature due to the proofs involving double discrete logarithms (Popescu et al. , 2003). Quasi-Efficient Revocation of Group Signatures This scheme is specified to address the inefficient and unsecured revocation methods use by other group signature scheme. The security of a group signature is not met if it uses an inefficient way of revocation. Additionally, the quasi-efficient revocation methods provide a practical public keys and signatures (Ateniese et al, n. d. ). The importance of a good revocation method is seen in groups with shrinking number of members. The security of the group is compromised if the revocation process is not well established since a revoked member can still sign in spite of the group (Ateniese et al, n. d. ). There are a number of group signature scheme which provides good revocation methods but they need to use synchronized clocks and the signature size is relative to the number of revoked members. The use of loosely synchronized clocks in revocation of membership needs to notify all existing members about the revocation. It modifies the membership certificate of all members and consequently, affects the size of group signature generated (Ateniese et al, n. d. ). This revocation method is made in line with the ACJT signature scheme. The revocation methods can only be done by revising the backward unlinkability to unconditional unlinkability. However, the easiest way of revocation is reissuing of the membership certificates and regenerating the public key. This costs a lot of work to the group manager and the members since they have to repeat parts of the join process. Additionally, the verifiers need to be informed of the changes. However, there is a way to eliminate this inconvenience by generating public keys and membership certificates automatically. This is will eliminate the interactive process between the manager and the members. On the other hand, it has impracticality in the process since it requires issuance of new certificates to existing members (Ateniese et al, n. d. ). The efficient way to overcome this problem is to avoid issuing new membership certificates in the event of revocation of a member. This is done in some scheme in which they use a Certificate Revocation List (CRL). However, the schemeââ¬â¢s group signature presented contains an encrypted version of the CRL. It is necessary to prevent the linking of the group signatures. However, the problem is resolved here by including the latest CRL to the group public key in which the unlinkability is preserved (Ateniese et al, n. d. ). The efficiency of this scheme is measured by the size of the signature, the signer cost, verifier cost, CRL size, and the CRL issuance cause. This scheme had passed all requirements since it minimizes the size of the signature as it fixed, the cost of the signer is constant, the verifier costs is also constant, the CRL size is inevitably rising but it is minimize and the CRL issuance cost is also unavoidable, however it is the least significant (Ateniese et al, n. d. ). The revocation method with the ACJT group signature scheme had been proven to be efficient and secured. This more practical than other group signature due to its features that fixes the size of the signature and requires constant work by signers. However, the ACJT group signature scheme requires the use of proofs-of-knowledge involving a double discrete logarithm (Ateniese et al, n. d. ). Conclusion These articles had proposed changes to other group signature schemes and some presented their own schemes. Generally, these articles aim to the advancement of the concept of group signature in relation to efficiency. The articles above had proposed methods of how to satisfy six properties needed fro a secure group signature scheme. These schemes are still subjected to further research to optimize its efficiency without compromising its security. References Ateniese, G. , Camenisch, J. , Joye, M. , and Tsudik, G. (2000).
