Letters of credit have been described '' as the lifeblood of international commerce'' . ( Kerr L J in R D Harbottle ( Mercant - Essay Example They are Open Account, Bill of Exchange, Documentary Bill and Letter of Credit.1 Open Account is a type of practice whereby contracting parties agree on payment of cash against order. This means the importer has to make advance payment along with his order. The risk for the importer is at a maximum. On the other hand, exporter assumes equal risk if he agrees to ship the goods and receive payment at a later date on or after delivery. Secondly, bill of exchange is an arrangement by which the exporter obtains an undertaking that the importer shall pay the value of goods received after a certain period from the date of supply, delivery or against despatch as the case may be. This is a negotiable instrument just as a cheque or promissory note and it is governed by the Bills of Exchange Act 1882. In case of default by the importer in payment, the exporter acquires legal rights to proceed against the importer. This arrangement is safer than an open account type of payments. The third type o f payment Documentary bill refers to Bill of Exchange accompanied by the bill of lading which is document of title to goods. The Bill of exchange drawn by the exporter along with the bill of lading for the goods shipped is accepted by the importer for payment as per the negotiated terms as to whether it is payable at sight or after a period of say 30 to 90 days. These three types of payment do not guarantee payment or shipment (in case of advance payment by the importer) to the respective party. The last of the above said types is the letter of credit. This form of payment removes difficulties encountered by the parties in the first three types of payment. The letter of credit has therefore been regarded as life blood of business as rightly said by Kerr L.J.2 This type of payment wherein third parties step in to guarantee payment thus lubricating the wheels of commerce is however not without problems that would affect the interests of either party.3 This paper discusses the importan ce of letter of credit as the lifeblood of international commerce in the following pages. Letter of Credit The letter of credit opened by a bank on behalf of an importer guarantees payment to the exporter in a foreign country through his nominated bank. Thus, the importer’s bank after satisfying with the credentials of the importer who may be its long standing client and taking necessary precautions to collect payment from its client, sends an irrevocable letter of credit as per the terms and conditions agreed upon between the importer and the exporter to the exporter’s bank. The exporter’s bank in turn forwards the letter of credit to the exporter and intimates the fact to the importer’s bank. The exporter ensures the compliance of stipulated terms and conditions and ships the goods to the importer. The bill of lading which evidences the shipment of goods and becomes the document of title to goods, is submitted to the exporter’s bank along with ot her documents such as invoice, certificate of insurance, certificate of origin etc and the bank is instructed to collect payment for the goods shipped against delivery of the said documents to the importer’

Reading Report Essay Remedial phonics teaches students to break words down into phonemes or speech sounds, the smallest units of spoken language. Students must learn to recognize phonemes and their corresponding letter combinations to the point where it becomes automatic. This requires a lot of drill and practice in two directions: auditory to visual, and visual to auditory. In auditory drills, students might listen to the phoneme and write down the corresponding letter. In visual drills, they might practice recognizing letters and sounding them out. Teaching students to recognize and use different types of syllable is another crucial element in a remedial phonics program. A key skill in learning to read is dividing longer words into syllables. Once students have mastered the basic phonemes, they are ready for a more advanced study of morphology, which breaks down words into their smallest units of meaning. These units, called morphemes include affixes, base words and roots. Syntax (formal grammar) and reading comprehension strategies are also taught. Traditional classroom teaching tends to emphasize auditory and visual learning, but does not give students much opportunity to use touch or movement in acquiring new information and skills. Remedial phonics instruction must utilize all three learning pathways simultaneouslyauditory, visual and kinesthetic-tactile. READER’S LOGIC: Intensive phonics instruction is widely regarded as the best remedial approach for students who have difficulty learning to read and spell. This is especially true of intelligent children who are less sensitive to the speech sounds that make up words, or who may have difficulty with visual processing. There are no quick fixes, but with the right instruction these students can learn to read and write as well as anybody. Elementary Reading Help: Reading Aloud to your 3rd and 4th Graders AUTHOR’S LOGIC: Reading is a basic focus and receives a lot of attention in class, but there isnt enough time in the school day to reinforce all the skills your child is expected to master. Elementary school students benefit from any outside help they can get to help them master the fundamentals of reading. Parents can help by reading aloud with their students. Reading aloud encourages students to practice reading skills like clear enunciation. It can allow parents to monitor their third and fourth graders reading. Best of all, reading aloud can help bring your family together. Many families have a hard time developing, and sticking to, a reading schedule. But the sessions dont need to be long. You can build it into the bedtime ritual. Its a great time for you and your student to bond and relax before going to sleep at the end of a hectic day. If you have more than one child, try reading with each child separately. This gives children the chance to read at their own pace and ability and creates a special time for just the two of you. Parents can create a reading ritual very early in a childs life. In fact, within the first few months of life, an infant can watch pictures and listen to your voice as you read. You can help your baby or toddler with word recognition by pointing at an object as you say the objects name. Have your child follow along with the words using their pointer finger. By reading together, you can select works that are slightly beyond their current reading skill level. Helping your child with words and concepts they dont understand will build their vocabulary. Its a great way to foster growth without the pressure of assignments that comes with school lessons, which can be discouraging. Letting your child read something they like is the best way to help them see the value of learning to read. After finishing your reading, make sure to leave ample time to discuss the story afterward. This will help you determine if your elementary school student is comprehending the stories and strengthening their reading skills. Ask questions during the reading so you can reread any parts of the story your child has missed. Let your child quiz you as well. This will keep him or her involved in the story. READER’S LOGIC: One of the best things a family can do to promote reading is to read books to each other, aloud. Read on to learn how to start a family reading program that will be beneficial to your elementary school student. Making the Home a Reading-friendly Place AUTOR’S LOGIC: One of the most important things a parent can do to create friendly learning environment is to ensure their children have access to all of the necessary materials. Parents should stock paper, pencils, pens, crayons, and markers in an area their child has access to. Additionally, make sure there is a table where your child is comfortable drawing and writing. Alphabet and word magnets can help foster creativity in children. The magnets allow children to learn their alphabet, spell out words and write sentences. A variety of age-appropriate books is also important in creating a reading-friendly household. Parents should aim to expose their children to numerous writing styles and resources. For example, a parent of a small child should have at least one alphabet book, several rhyme books, picture books, and books of short stories. Each type of book will help your child develop the skills he or she needs to become a well-rounded reader and provides your child with the freedom and opportunity to explore reading on his or her own. You and your child can expand reading options by visiting your local library or book stores regularly. Take your child when you go to the library and bookstore to expose him or her to all of the reading possibilities that are available to children of their age. Supplying a child with reading and writing supplies is not enough by itself. Parents should read with their children at home. It is recommended that parents read with their child several times a week. Reading together will encourage your child to explore this skill on their own. Additionally, it is the parents opportunity to teach basic reading skills. Start reading to your child as soon as possible, even when they are still infants. This will help you develop the habit and skill of reading aloud. Reading to a baby and toddler will also help them with word recognition and vocabulary. Parents are also encouraged to help children learn the alphabet and how to properly write the letters of the alphabet. Expanding a childs vocabulary and verbal communication skills will encourage them to improve reading. Try to teach your child several new words each week and show him or her how to use them in a sentence. Parents should also encourage their kids to talk about their day and various experiences like parties and field trips. Doing this will help a child learn how to convey thoughts and how a story is formatted. Reading your own books, magazines and newspapers also helps to create a reading-friendly household. This is because you are setting an excellent example for your children. Youngsters often copy their parents actions, so reading on your free time will encourage them to do this action as well. Children will fail to value reading if their parents never take the time to read! READER’S LOGIC: Parents should strive to create a nurturing household. One aspect of a nurturing environment is making the home an environment that welcomes reading. Read on to learn more about making your home a reading friendly place. In order for a child to excel at school, he or she must be exposed to pre-reading and reading skills in their home. Many parents are unsure exactly what type of activities to implement in order to create a reading-friendly house environment. Working with your Child to Develop Stronger Math Skills AUTHOR’S LOGIC: Be sure your young learner has a mastery of creating the numerals in writing. Its a separate skill. Some children can count and even add large numbers in their head or with props from a very young age, but have difficulty when it comes to working it out on paper. Games are a great way to build understanding. In school math can be just another subject. Building a recognizable link between school work and daily  life is crucial to education. You can get board games, computer games, online games, or you can just make adding or sequence games up as you ride along in your car. Find math in the kitchen, in the garden, in the play room. Number games make counting and working with numbers a fun part of life instead of a daunting required subject. Understanding spatial relationships is an often underestimated but fundamental skill. Just making a letter fit on the line involves the ability to estimate and work with space. Measuring furniture, floor space, the distance from the bedroom to the bathroom are all great exercises. You can work with inches and feet, and convert from one to the other. In time youll be able to explore the metric system and begin measuring volume. This will help give your child a sense of how things fit together and how to work with the numbers that describe those relationships. The math children use in school is just a formal application of all kinds of daily experiences. When a child makes that realization, a light will go on and hell become curious. When curiosity sets in, learning becomes fun. When learning becomes fun theres no stopping it! A child who struggles with math at school doesnt need constant drilling of specific problems. He needs varied experiences that allow him to work with numbers in a hands on way. When he has the concepts woven into his perspective, hell be better equipped to handle the formal arithmetic he encounters in the classroom. READER’S LOGIC: Math skills develop from every day life experiences long before they are formalized in the classroom. From writing the numerals correctly to grasping basic math facts, you can help your child develop math skills according to their natural ability and learning style. Children develop math skills at different rates and in different ways. A common problem is that a child has trouble remembering math problems no matter how many times they review them. Its important to stimulate a childs mind in various ways to reach him as an individual and build a connection between his mind and the material he needs to master in school. Here are some ways to approach the teaching of math and things to watch for that take into account the varied rates of development in different children. Teaching Reading to Older Kids Who Have Learning Disabilities AUTHOR’S LOGIC: Short vowels usually occur before one or more consonants when in closed syllables. Students can be taught to read the syllables and then to spell them in longer, age-appropriate vocabulary. Once they have six or seven syllable types under their belts, students can chunk sequences of letters together, recognize them visually as a unit and understand spelling patterns. As syllable recognition develops, students can learn more about prefixes, root words and suffixes, to the point where they can link meaning with the spelling components of the new words they encounter. Some learning-disabled readers struggle with word retrieval. That means they dont develop word sufficient word recognition. Quick speed drills can develop automatic recognition of syllables and words and phrases. In one drill, a student will read several lines of easily confused syllables, such as pre, pro and per. Other methods include taking turns with a passage in a group setting, reading along with a tape-recording, reading an assigned part in of a play and rereading familiar text. Teachers use new words as often as possible in classroom conversation and reward students for noticing, or if the student uses the word outside of class. Students are taught to use context, root words, word origins to figure out word meanings. In the best case, word study will linked to class subjects. READER’S LOGIC: Learning disabled students struggle with math and reading, but socially they can be as developed as their classmates. Age appropriate settings and methods help older students who struggle with learning disabilities to acquire the math and reading skills they lack. Techniques for teaching older kids to overcome their reading disabilities enables students to learn in an environment appropriate to their age and social development. Students who progress in reading at a normal rate can read most of the words in their daily vocabulary by 4th or 5th grade. After that, new words come at the rate of several thousand new words per year, primarily through reading. Most older readers who suffer learning disabilities are exposed to more spoken words than they can read. Older students have to overcome a huge vocabulary deficit before they can get beyond the 5th grade reading level. The following are three common areas where older reading-disabled students tend to struggle, along with methods employed to teach them what they need to excel beyond the limits of their disability.

Emerging House Husbands :: Research Sociology Home Caregivers Essays

The out-dated stereotype that men are better workers than women is now more laughed at than believed. Yet, the stereotype that women can take care of the household better than a man has not changed. Extensive research proves that â€Å"house husbands† are more popular than ever imagined; they have their own websites, groups, and how-to books. House husbands are becoming much more popular, but are they being appreciated the same as house wives were. The simple definition of a house husband is a married man who either chooses to not hold a career and assume all household responsibilities such as cooking, cleaning, bill paying, full child care, and necessary evils such as, buying stamps in the absence of their fulltime working wife. (Heiman 122) It can also be a man who does hold a career but chooses to have a â€Å"second shift† by coming home and assuming household responsibilities. At the end of 1987 15% of married men chose to become house husbands (O’Sullivan). According to the U.S. Census Bureau, there were 189,000 full-time, stay-at-home dads in 2002, up 18 percent from 1994. But dads' groups say that estimate is the result of too-restrictive criteria, and they put the number at closer to 2 million. Now, some may not consider this to be a huge leap, but take into consideration the standard of living has also grown. Also, many people still regard women as the care takers of the house, and a man assuming this job is odd and unacceptable. The option of becoming a stay at home dad might be more realistic than it seems. If a father is considering staying at home, they examine their earning power as compared to their partner's. They consider work attire (no need for power suits), as well as commuting costs (gas, wear-and-tear of the car, depreciation, extra insurance costs), daycare costs, and all the other expenses of working (Father Time). A slight repetitive blemish is embedded along with the idea of house husbands. Women statistically make less than men; even if they are working the same job. (Nair 47) Most employers well tend to give men a better income because they are traditionally the â€Å"sole bread winner for their family.† (Arendell 157) They give less to women because they believe she already has a man taking care of her and any children she has. This can easily discourage men because their well-known egos can get the best of them, especially when it comes down to the green.

Anne Bradstreet as First American Feminist Essay -- Anne Bradstreet Fe

Anne Bradstreet as First American Feminist Feminism today remains prominent because even while women’s rights are very strong, women are still fighting for equality every day. In the time of Anne Bradstreet, women had few rights and they were seen as inferior to men. Anne lived among the puritans whom ruled her everyday life. Although it was against the puritan code for women to receive an education, Bradstreet’s father, Thomas Dudley, loved his daughter dearly and made sure that she was well educated which shows in her works. Anne Bradstreet’s literature became well known only because her family published her works under a male name. This was done because writing poetry was a serious offense to the puritans since poetry was considered creative and the only creating that was done was by God. In the works of Anne Bradstreet, she conveys a feminist attitude, and could very well be one of the first American Feminists. Bradstreet was very religious, and the religion she faithfully followed was very male dominant. Perhaps this is why Bradstreet never had a strong voice. Surely if she were to have voiced her opinions loudly and strongly she would have suffered dire consequences. Anne Hutchinson was banished because she publicly voiced her objections to the code of puritan lifestyle and beliefs. Living in a harsh puritan society most likely intimidated Bradstreet, so instead, she carefully weaved her early feminist thought into her poems and stories so that they weren’t too apparent. For example, in †The Prologue,† Bradstreet conveys knowledge of recognizing the kind of patriarchy she lives in, in the fifth and sixth stanza. I am obnoxious to each carping tongue/ Who says my hand a needle better fits,/ A p... ...sband, mothered eight children, risking death from each pregnancy, and managed to live sixty years. She was the first woman in American Literature to have her work published and also one of the first American women to begin thinking as a femenist. Even though Bradstreet was not a prominent, public femenist, she realized that she had to start somewhere and due to her living in the strict patriarchal puritan society, she did what she could. Although Bradstreet was very religious and held her spirituality very close to her, she still put together early femenist thought and can be considered one of the first American femnists.

Market Segmentation for Lawn Mowers Essay

Introduction In this document, we will analyse the current market of lawnmowers in Portugal. By recognising this market and its products with distinct characteristics, we will perform a customer segmentation, which will allow us to divide the market into small groups. Through the segmentation of the lawnmower market, it will be possible to achieve a greater proximity to the final customer; create advertising media that target the identified segments; facilitate the positioning of the product; and obtain the return on investment by the company. The developments and technological diversity provided by all the competitors operating in the sector has shown that this market is very competitive nowadays. Thus, it is imperative that a strategic shift is implemented, which is more focused on meeting the needs of the customer. The notorious falling sales in the sector since 2008 were of equal importance, although the explanation of this phenomenon lies in the national and international economy situation. To analyze the current market of lawnmowers in Portugal, we started to make a small market research. To get a concrete â€Å"shape†, we went to one of the biggest players in the market – Leroy Merlin, who kindly gave us some informations which served as basis for this assignment and which allow us to have a better vision of what is happening in the lawn care industry. GOALS By segmenting the market of mowers you can:  · Get a closer relationship with the end consumer;  · Create advertising media that are targeted to the identified segments;  · Facilitate the positioning of the product;  · And monetize coveted by the company. This last point is usually associated with Increase sales, Increase profits, Increase sales dealer channel. Segmentation There are several types of lawnmowers available on the market: manual, battery – powered or gas – powered models, are some of the options. There are ways to segment the lawnmower market : Customer characteristics †¢ Geographic ( region, city size, and so on ) †¢ Demographic ( gender, age, race, household size, and so on ) †¢ Socioeconomic ( income, education, occupation, and so on ) †¢ Psychographic ( lifestyle, personality, and so on ) Buying situation †¢ Benefits sought ( product features, quality, service, warranty ) †¢ Usage rate – quantity purchased during a specific period Based on the market research that we conducted, we restricted the types of lawn mowers to non-powered, powered and powered riding for three different market segments : urban, suburban and rural. (POR TABELA DE PERCENTAGEM) The percentages given are based on the literature, as well as the information given by the head of the gardening sector at Leroy Merlin, which we visited, in Alfragide. Against this backdrop, the most attractive segment seems to be that of the consumers who live in the suburban area and who use powered walk-behind lawn mowers. However, this segment may already be flooded with competition, it may be more beneficial to target a small segment of consumers, like urban consumers using non-powered or powered walking mowers. The smallest segment may be the most profitable and lucrative. Conclusion From our research we ​​can segment the market of lawnmowers in Portugal as: mainly directed to male gender, between 35-55 years old, who lives in the suburbs of large cities, in a house with a garden area between 1.000 to 2.150 square feet of grass; with a household of four people and average income between â‚ ¬ 20.000 and â‚ ¬ 30.000 per year. The most chosen mower for this kind of segment is the electric powered one, in spite of major disadvantage of requiring a wire plugged to work, which makes that their use is impractical for those who have large estates. It is noteworthy that one of the great advantages of an electric lawn mower is that it does not require extensive maintenance. With the displacement of many ex-urbanites to the most suburban areas of large cities, the growth of lawnmowers little by little began to live better days. With this segmentation, we believe that  the Finnish company will take advantage of this kind of market penetration. Faced with fierce competition (AKI Group, IZI-MESTRE MACO, LEROY MERLIN, BRICOMARCHÉ, BRICO LECLERC and also in many other customers in traditional market said: Garden Centres, Hardware Stores, Drugstores, Building Materials Stores and other sited North to South), the Finnish company will have to differentiate the products presented, as well as in the developed marketing campaigns, satisfying specific needs and desires of this kind of consumers.

Impact of corporate governance on the financial pe Essays - Economy

Impact of corporate governance on the financial pe Essays - Economy Impact of corporate governance on the financial performance of Nepalese Enterprises Lilesh Kumar Yadav, LumanaTamrakar, Manika Shrestha and NamrataPandit Abstract This paper empirically examines the relationship between corporate governance and performance of Nepalese enterprises. The performance variables used in this study are return on assets and return on equity and these are the dependent variables. The corporate governance variables such as board size, audit committee, board diversity, ownership structure and control variable such as leverage and firm size are the independent variables. The population of this study consists of financial and non- financial companies listed in Nepal Stock Exchange (NEPSE). Total number of 27 financial and non- financial companies listed in Nepal stock exchange for a period of five years from 2011-2015 are used as the sample size. Data are collected from annual report of the respective firms. The pooled cross sectional data analysis has been carried out in this study. The multiple regression models are applied to test the significance and important of corporate governance in the Nepalese firms. The study reveals that board size, leverage and firm size are positively related to return on assets of non- financial firms. This indicates that large the board, leverage and firm size, higher would be the return on assets. The results also show that there is negative relationship of return on assets with audit committee and board diversity. This indicates that higher the audit committee and board diversity, lower would be the return on assets. There is a positive relationship of return on equity with board size, leverage, firm size, and audit committee and board diversity. In the case of financial firms, the study reveals that there is a positive relationship of return on assets with audit committee and firm size. This indicates that higher the board size, leverage and firm size, higher would be the return on assets. The regression result shows that the board size, leverage and firm has positive impact on return on assets in the case of non-financial firms. Similarly, in the case o f financial firm, there is a positive impact of ownership structure, audit committee and firm size on return on assets whereas the coefficients are negative for board size, board diversity and leverage. Keywords: return on assets, return on equity, board size, ownership structure, audit committee, board diversity, leverage and firm size. 1. Introduction Corporate governance is the system by which companies are directed and controlled. It is also argued that the corporate governance is the framework by which the interest of various stakeholders is balanced. It shows a set of relationship between a company's management, its board, its shareholder and other stakeholder. Corporate governance provide the mechanism by which the problems of corporation stakeholders, which include the shareholders, creditors, management, employee, consumers and the public at large are framed and resolved. The Organization for Economic Cooperation and Development (OECD) also defines corporate governance as the system by which business corporations are directed and controlled. The Asian Development Bank defined the concept as the manner in which authority is exercised in the management of a country's social and economic resources for development (Eng Mak, 2003); corporate governance has become a topical issue because of its immense contribution to the econom ic growth and development of nation. The absence of good corporate governance is a major cause of failure of many well performing companies. Existing literature generally support the position that good corporate governance has a positive impact on organization performance (OECD, 2009). Effective corporate governance has been identified to be critical to all economic transactions especially in emerging and transition economies (Dharwardkar et al., 2000). The concept of corporate governance has been increasing public interest in recent years due to its plausible importance on the economic health of corporation in general. Good corporate governance practice provides a means to recognize the dreams of justifying risks and optimizing performance concurrently in today's aggressive and regulatory setting. Corporate governance lays down objective framework for creating long term trust between company and its stakeholders. It is solved by rationalizing and monitoring risks of a company, limiting liability of top management by carefully articulating decision making process, ensuring integrity of financial reports, and finally providing a degree of confidence necessary for proper functioning of an

Conjugating Croître in French

Conjugating Croà ®tre in French In French, there are a few options for saying to grow. One of those is  croà ®tre  and is the subject of this verb conjugation lesson. Yet, you may also wish to learn or use the verbs  grandir  (to grow)  and viellier (to grow old)  as well. Conjugating the French Verb  Croà ®tre Verb conjugations are required to express the verb in the present, future, or past tense. For instance, growing and grew are English conjugations, though in French things are a little more complex. Thats because we must be concerned about the subject pronoun as well as when the verb is happening. Croà ®tre  is an  irregular verb, meaning that it does not follow a standard conjugation pattern. You will need to memorize these conjugations without the help of any similar verbs you may already know. Yet, once you identify the endings for  croà ®tre, they can also be applied to accroà ®tre (to increase)  and dà ©croà ®tre (to decrease). When studying these conjugations, watch out for the changes to the verb stem. Some replace the circumflex à ® with an I and in others forms, you will find a circumflex à » in its place. This is a rather tricky conjugation, so take your time. Using the table, pair the appropriate subject pronoun with the verbs tense. For instance, I grow is je croà ®s while we will grow is nous croà ®trons. Subject Present Future Imperfect je croà ®s croà ®trai croissais tu croà ®s croà ®tras croissais il croà ®t croà ®tra croissait nous croissons croà ®trons croissions vous croissez croà ®trez croissiez ils croissent croà ®tront croissaient The Present Participle of  Croà ®tre The  present participle  of  croà ®tre is  croissant.

Did women have a Renaissance in Early Modern Europe Essay - 2

Did women have a Renaissance in Early Modern Europe - Essay Example This period also saw the cropping up of secularism in which people started focusing on worldly ideas and ignored God (Kreis, 1). Life became something to enjoy and not a difficult journey to heaven as it was before. Renaissance was more defined among men than it was to women. Everywhere across Europe, women were not accorded respect. They were placed under the shadow of their husband by the ancient society. They had limited education, enlightenment and exposure. Their husband restricted them to domestic activities as it was recommended by the society. Even with the early European modernization, women still lagged behind in the society where men led. During the early modernization in Europe, women had no renaissance because they had no enough experience. They were characterized with less knowledge compared to men due to their low education. Although many schools were opened during renaissance, they were attended by men (Kelly-Gadol, 24). This restricted women from getting adequate education that could give them renaissance. Most of the women remained at home to run all domestic chores. Only women from wealthy families could get higher education as they could afford private teachers. These were however restricted from learning some things such as man art. All the stakeholders in the education sectors and decision makers could not allow women in schools because society did not allow women to participate in public activities (Kelly-Gadol, 15). At his time going to school was taken to be a public activity. The educated women tried to set the example to the uneducated. This challenged them to work hard to be educated although even wi th their education they were seen lesser than men. The learned women could remarry when widowed as the case in lecturer 1 where a woman widowed four times was still looking for a husband. In arts, the women artists had similar background as the only those from wealthy families could be allowed to be artists (Clare,

IT corporate governance Research Paper Example | Topics and Well Written Essays - 1250 words

IT corporate governance - Research Paper Example As for effects on public organizations, especially until recently, research has been scarce (Colley 2003). The rational for the research paper is to investigate and analyze new trends in information systems application and their impact on information, effects on corporate design, structure and productivity. It is assumed that advances in technology, especially computer, information, and information technology, have presented organizations and managers with dramatic new challenges and opportunities, and researchers have been pressing to develop the theoretical and research grounding needed to understand and manage these developments. It is supposed that information technology allows a corporation greater decentralization of functions thus ensuring effective management and control. Computers, the Internet, electronic mail, and other forms of information and information technology make possible more elaborate and interactive networking of people and organizational units, both within and between organizations (Dine, 2000). Some organizations have moved away from traditional hierarchical and departmental reporting relationships to forms of virtual organization and dynamic network organization, in which a central hub coordinates other units that formally belong to the same organization, as well as organizations formally outside the hub organization (such as contractors or agencies with overlapping responsibility for public agencies), via e-mail and the Internet. Advances in IT reportedly lead to smaller organizations, decentralized organizations, better coordination internally and with external entities (Buck and Sha hrim 2006). Organizations acquire and distribute internally information to carry out the critical functions of decision-making. These activities require the processing of information. There are two perspectives on organizational

Fortifying U.S. National security Essay Example | Topics and Well Written Essays - 4000 words

Fortifying U.S. National security - Essay Example To respond to the first two revolutions requires foreign policy initiatives in the Middle East and elsewhere as bold as the Marshall Plan and as encompassing as energy security. (Tucker, 2006) To create a national security strategy requires an understanding of the changing nature of conflict particularly, and that requires an understanding of the erosion of the sovereignty of nation-states. For 350 years, wars have been fought between the uniformed armies of nations with fixed borders, meeting in the field to achieve a political result. Rules evolved for these wars: Geneva conventions and a body of international law spell out the norms for humane treatment and repatriation of prisoners, the rights of noncombatants, rules against the use of torture, and so forth. Nations disintegrate; and when a nation disintegrates, as in the former Yugoslavia, geographic borders warp and sometimes evaporate. (Clancey, 2006) Indeed, part of the process of creating peace among ethnic combatants in a disintegrating nation involves drawing new boundaries and building new nations. And now, in the new age of terrorism, United States experience violence being perpetrated by combatants in civilian clothes, representing no nation, attacking civilian targets, with no political agenda, and possessing only a fanatical commitment to destruction for its own sake. When the nature of conflict changes, the means of assuring security must also change. New forms of violence resemble war, but by historic standards they are not. What is this new conflict, and how should United States deal with it United States call much of this new kind of violence terrorism. But labeling every bad actor a terrorist tempts us to embrace wretched allies on the always-dubious theory that the enemy of our enemy is our friend. On this same theory, United States supported undemocratic and repressive authoritarian oligarchies during the Cold War simply because they were opposed to communism. (Howard, 2006) United States set about assassinating foreign leaders United States did not like. The bills United States accrue from despicable allies and unprincipled policies that undermine the very principles United States claim to defend, however, always come due. In the past ten years, United States have seen a dozen or more low intensity conflicts between tribes, clans, and gangs. United States participated in some, including in Somalia, where United States experienced the painful consequences of brawling, however well intentioned, in another man's alley as memorialized in the fi lm Black Hawk Down. United States passively observed similar bloody confl icts, in Rwanda and elsewhere, where the weapon of choice, a machete, dated to the Bronze Age. (Korb, 2006) United States successfully formed a "coalition of the willing," essentially an ad hoc international posse, in Bosnia, Kosovo, and Kuwait. United States earned a quick victory in Kuwait largely due to intensive bombing and maneuver

Argument - Essay Example scribes the preference given by educational institutions to certain applicants on the basis of their familial relationship to alumni of that institution. There is a long history of legacy admissions at American universities and colleges. Ivy League institutions such as Yale, Harvard etc. are estimated to admit 10% to 15% of freshmen based upon this factor. (Lexington). Harvard actually has special levels of legacy preference, methodically and elaborately distorting its standards on behalf of its alumni. The family of middle-class alumni enjoys a modest edge; the children of major donors receive double preference in the case of admissions. (Daniel Golden) This fact is confirmed by national surveys conducted by American Association of College Registrars and Admission Officers showing that legacy admissions are made at both public and private institutions. Also supporting are the statistics that show the percentages of legacies in different colleges that are definitely more than affirmative action admissions- Notre Dame 23%, Harvard 11%, University of Pennsylvania 14%, Princeton 11% and University of Virginia 11%. (Howell & Turner) Colleges should not give any preference to those who are more likely to have other socioeconomic advantages anyway, such as the children of alumni. Admissions should be made strictly on the ground of merit and exceptions should be made only on morally acceptable grounds such as talent and underprivileged class or race etc. A great example of the injustice of the legacy system is George W. Bush who was admitted at Yale in 1964 with an average grade of C and SAT verbal score of 566 just because he was a third generation legacy. How do you justify that? His admission and of those like him reduces the admission chances of meritous students who expend enormous effort in getting good grades or honing special talents this practice also uses up seats reserved for affirmative action admissions of blacks and others. Affirmative action refers to

The Experiences of Dick Spencer in Modrow Plant of Tri-American Essay - 1

The Experiences of Dick Spencer in Modrow Plant of Tri-American Corporation - Essay Example Dick inherited problems at Modrow plant; he was not included in initial planning and spent a lot of time in getting up to speed. His friendly and easy going attitude was not appreciated in the English plant as well as the Modrow plant by Canadian workers, as his casual strolls were considered as suspicious and steadily his stature and authority as a plant manager was undermined by the workers. The limitations he had as a leader was his inability to understand accounting practices and delegating tasks to his sub-ordinates, as a result he started taking interest in minor or unimportant issues of the plant. This micro management kept him away from core issues rising from expansion and modernization of the plant. His attempts to gain insights by spending time in manufacturing area were not ideal and a trusting behavior towards middle management should have brought better results in implementing the changes he wanted. He was not furnished by the relevant information by middle management a s they had doubts about his abilities as a leader additionally his obsession for gaining insight from workers left the middle management with lack of trust in him. In order for a successful change to come whether it is cost saving initiative, modernization or expansion Dick should have paid attention to more strategic issues of the time and used his time for inculcating trust within management, there are many leaders who lack the technical knowledge or experience but they achieve results by leaving the technical aspects of the work to technical staff communicating with their line managers and not seeing everything as a potential for cost saving initiatives. A gradual or incremental change would have helped Dick in first normalizing the situation due to his appointment ahead of local operating staff, gain trust of managers by staying away from the workers followed by understanding the modernization and expansion challenges.  This change is suggested keeping the personality of Dick in consideration, consequently an authoritative leader would have opted for a rapid change while resisting forces would have been removed or sidelined.

Media in Goa Essay Example for Free

Media in Goa Essay I can proudly say that I was the first television journalist to start work from Goa, till then Channels from Mumbai Delhi only sent their camera team and reporters for any major news event happening here. A decade later today its great that we have a number of local television channels and a 12 hour news channel as well. In that regard Goa Newsline was our first major step towards setting up of this industry in Goa. After 2 years of Newsline a number of other channels had jumped into the news making fray and the rest as you all know is there for all of us to see. I completed my Masters Degree in Communication studies from the Department of Communcation Studies University of Pune as there was no Journalism related course in Goa then. After that I interned with Zee News Noida and underwent practical training in Electronic News Media . Thereafter I joined Asian News International (ANI) and joined them as a Correspondent Camera-person for the state of Goa. Thereafter I joined Aaj Tak and worked for them as their Goa Correspondent, My father Mr. Waman Prabhu is also a journalist and was in the print media. As the electronic media fever caught up he joined Zee News as Goa Correspondent and together we covered Goa in all its splendour for these national channels. In this entire process there was a feeling that Goa was not being given due coverage on National TV and all the snippets that were shown of Goan Festivals and Events were not doing justice to the actual event. There was so much that was happening in Goa yet the national channels were just not interested. All that mattered to them was the Goan Carnival Christmas and New Year in Goa. And we all know that there’s so much more that the rest of the country needs to know about Goa. That was the time when the thought of a Goa News Channel crossed our minds and we both along with my younger brother Pravesh went ahead with a Goa News Channel. It was a tough exercise. Covering Goa for national channels was completely different.. for a local news channel the same had to be done in a local perspective. We started with a half an hour news bulletin which covered all aspects of the state the political,social,religious and sports aspect of Goa. It was Feb 2002 Goa Newsline was a valentine gift to the people of Goa. Because till then they could only rely on the erratic Doordarshan round up of events which happened every week. When we started Newsline we opted for Konkani as our news language because it was a language tht could connect us to the people of Goa. It was sheer hard work because our effort was to deliver todays news today-all over Goa. We wanted the people could watch the news at home before they read it on the papers the next day,that was the USP of our news. We dealt with time constraints as there was no highend editing software at that time with us. But yet we managed fine all the morning/ afternoon events were incorporated in our news bulletin. Yet another hurdle that we faced was initially people were reluctant to air their views on Camera, the concept looked good on national tv but it was difficult to accept it initially. Politicians too hesitated over how and what they spoke on local tv but gradually the transformation took place And once the news began there was a flood of appreciation that motivated us to perform better. We had no high end machinery and no spacious studio. Yet we had to deliver CD’s to over 23-24 locations everyday at a given time and the manpower—just the three of us. My father wrote the newsscript, Pravesh did the shoot and edit on camera and I read the news and pitched in for the filming of events as well. It was an effort that met with a lot of praise and also its share of criticism. I am glad that happened then as we complete ten years of Newsline this February. Goa Newsline was what everybody living here needed because audio visual media has its own power –the power of delivering an event happening in some place of Goa that you can relate to right in your home. It was a novelty in the beginning and we had endless lists of people who wanted us to cover their events -some interesting some trivial. It wont be wrong to state that Goa Newsline started the chapter of Electronic TV Journalsim in Goa and that it continues to have a loyal viewership in this day and age of Direct Transmission to Homes like Dish TV etc. It’s a challenge now to maintain the erratic cable connections when you have a no hassle set top box installed on your tv providing you crystal clear transmission but people here have still maintained their cable connectitons nly to watch the news programmes that are aired on these cable channels. So in a way it is also right that the cable industry in Goa is surviving on the hefty fees that these channels pay them and the connections which have not yet been replaced by Dish TV for the sake of Goan News updates. I feel the cable network industry should in turn protect the interest of the news channels in order to strengthen the chances of their survival.

Development of Cryptography Studies

Development of Cryptography Studies 0.1 Abstract This report is an overview of some structures that have heavily influence the course and study of Cryptography the last decades. Initially, we will analyse the structure of some important ciphers such as DES, 3DES and AES by underlying some dark and complicated points and emphasizing the critical  functions called S-boxes. We will then expand of some basic attributes of these block ciphers, for example the running time of them and their hardware and software performance. Finally, we will focus on a highly important aspect of these cryptosystems, security by exploring some of the most significant attacks that have been discovered against them. The paper is concluded with a presentation of the most important results of our investigation. 1 Introduction Cryptography has a very rich history, rooted back in the ancient years. Even Greeks of classical times have demonstrated understanding of ciphers, with the example of Herodotus to be the most well known, who tattooed a message to his slave head on a slaves shaved head and hide it under his regrown hair. Before the modern era, cryptography had an absolute target the achievement of confidentiality of a message. The most crucial years for cryptography were undoubtedly the last century. The decisive step was an investigation of Claude Shannon, the father of information security. In his seminar at 1949, Shannon analysed and illustrated block ciphers and suggest that, if they are combined with some operations that can provide the whole cipher with permutation and substitution, they should be a reasonable option. A block cipher, is an encryption scheme that belongs in the branch of Cryptography that is called symmetric-key Cryptography. This name is justified by the fact that the parties th at are involved in the communication through the cipher use the same secret key. Later designed as iterated product ciphers, block ciphers are deterministic algorithms that operate on fixed length groups of bits, called blocks. The major attribute for a block cipher is that the length of the input, called plaintext, and the length of the output, called ciphertext, is always the same. They take as an input a key of k-bits length and the this key is expanded to many different keys following a sequence of operations, the so called round keys. Typically, a block cipher is built by iteration, using a function called round function. In every round, the round function takes as an input the corresponding message and the round key and produces a new outcome which is oriented to be used in the next round. The final round will produce the ciphertext. Block ciphers have been widely used and dramatically influence the new era of humanity, and more importantly for commercial reasons in industry a nd banking. There is a remarkable variety of examples from block ciphers, although for the rest of this paper we will focus on the most famous examples that dominated the whole area of symmetric-key Cryptography in the new era. These are called DES, 3DES, AES. Blowfish has also attracted the attention since there isnt still any known vulnerability but it will remain outside of the scope of this report. 2 Analysis and Description 2.1 Data Encryption Standard (DES) Nowadays, DES is considered to be insecure, but it had a huge impact in the development of the symmetric-key cryptography for many decades after its invention. It has been designed back in 1976, when the government of the United States realized the overwhelming necessity of an algorithm that could effectively protect government data and safely used for buying products from the international markets. The most interesting difference of DES with its predecessor, Lucifer, which has been designed by Horst Fiestel, is that the key length and the block length has been reduced significantly. Nevertheless, the key length, especially, was from the time that DES was published, under heavy criticism and was actually badly broken in 1997 with the so-called exhaustive search attack. That means that a machine was able to search all the possible keys and find the correct one. DES has a very rich history of attacks and we will examine some of these attacks in more detail later in this paper. The core idea behind DES is the so-called Feistel Network, where a block cipher can built up with the use of some arbitrary functions f0,f1,fd : {0,1}n → {0,1}n. There is a wide variety of block ciphers that have a similar construction, although AES has a completely different construction. The critical point in these kinds of constructions is the structure of these functions, which can vary significantly. Abstractly speaking, the main target is to construct an invertible function F : {0,1}2n → {0,1}2n in order to able to decrypt the ciphertext. DES is basically a 16-round Fiestel network. More specifically, the input is exactly 64 bits, so R0 and L0 are 32 bits each. Obviously, from the diagram above, in every the half of the bits remains unchanged. The other half comes with a sequence of operations. Initially, as specified by the protocol, a permutation of the whole input takes place, followed by a 16-round Fiestel Network. Each function f0,f1,f16 : {0,1}16 → {0 ,1}16 that is used at each round is computed by using the corresponding subkey, fi(x) = F(ki,x) ,in order to make the decryption circuit feasible and manageable from a hardware perspective of view. This subkey is produced by the main key, in the following way: 56 bits are selected from the 64 bits that contains the key, the 56 bits are divided into two 28 bit halves and each half is treated afterwards separately. In every round, both halves are rotated form the left to the right by one or two bits and then 48 bits are selected, 24 from the left and 24 from the right to build the corresponding subkey. After these 16 rounds of the Fiestel network, there is one more permutation before the final output is computed. The following image describes the construction of the fi function. Initially, the input of 32-bits replicates 48-bits with some simple calculations and then the result is XOR with the 48-bits subkey. The 48-bits are splitted to 8 blocks of 6 bits and passed to the S-boxes. This is the most critical point of a block cipher and bad implementation of S-boxes can easily compromise security. A S-box is a function {0,1}6 → {0,1}4 and acts like a look-up table. The selection of these tables is of vital importance and has been a controversial matter for many years. It has been proved that linear S-boxes is definitely not an option. Even a partly linear S-box can run under some kind of attacks. After the implementation of all the S-boxes, a last permutation that maps the 32-bits around, takes place. The decryption circuit follows exactly the inverse procedure. Obviously, the encryption and decryption circuit are almost identical as the only actual difference is the order that the f1,f2,,fd functions are applied. This fact made DES very attractive to hardware developers because they had to implement just one algorithm for both procedures. 2.2 Triple Data Encryption Standard (3DES) As already mentioned, DES has been proved to be vulnerable under certain types of attacks so significant has been made in order to improve the security of DES. For this reason, DES has been replaced by 3DES, which was published in 1998 To begin with, let E : KXM → M be a block cipher and lets define the function 3E : K3 → M as 3E((k1,k2,k3),m) = E(k1,D(k2,E(k3,m))), where D denotes the decryption algorithm. Actually, there are three encryption steps. The main question that arises here is why the middle one is a decryption algorithm and not and encryption algorithm. The answer is simple; this would have lead to the implementation of a single DES, beacause the first and the second DES operations cancel out. will cancel the other. Obviously, the key-size, as it was intended, has been increased to 168-bits, as each of the keys is 56-bits. There are three options for keys; in the first key options all the keys are independent, in the second option k1andk2 are independent and k3 = k1 and in the third all three key are identical, k1 = k2 = k3. The third option is no longer recommended by the NIST( National Institute of Standards and Technology), the first key option is the strongest with a total number of 168 key bits as mentioned above, and the second option is stronger that simply implementing DES twice. 2.3 Why not double DES? 3DES is considered to be a secure block cipher. Nevertheless, a normal question is why 2DES in not an option, as it may not seem easy to beak by brute force with a key-length space 2112. A 2DES can be defined in the following way; 2E(k1,k2),m) = E(k1,E(k2,m)) with a key length 112 bits. This construction turns out to be completely insecure and the reason for this is the meet-in-the-middle attack. Basically, if an attacker has at his disposal an actual message and the corresponding ciphertext, which will be of the same length, he will try to find a pair of key (k1,k2) that E(k1,E(k2,M)) = C. If we apply at both parts of this equation the decryption algorithm, then we get the get E(k2,M) = D(k1,C). So, the attacker will try to figure out which is the appropriate pair of key in order to map the message M and ciphertext C at the same point this also justifies the name of the attack meet-in-themiddle. The attack is structured in two steps: Firstly, the attacker has to build up a table wi th all the 2112 keys and the corresponding encryptions and then sort this list, and secondly, for all possible key that belongs to {0,1}56, he calculates D(k,C) and he looks for a match at the previous table. Whenever he finds the first match, his goal has been achieved. The running time of this attack is 256log(256) + 256log(256) < 263, time that is much smaller than the time that is necessary for brute force attack. 2.4 Advanced Encryption Standard(AES) It is widely acceptable AES has been adopted by the U.S. government and nowadays is used worldwide. As DES was proved insecure and 3DES quite slow, the demand for a more effective encryption scheme grew rapidly and at 1997 NIST requested a new proposal. After some investigation, NIST chose Rijndael as AES at 2000, a cipher that was designed in Belgium. AES, unlikely to its predecessor, its not a Feistel Network. In contrast, it is called a substitution-permutation network because both actions of permutation and substitution take place. AES has a fixed block size of 128-bits, although the key length can vary, 128,192 or 256 bits. Additionally, in every round of AES all bits change while in every round of DES half of the bits remain unchanged. Generally, a substitution permutation networks initial input is operated with an XOR with the corresponding round subkey, then goes through a substitution layer where there are some blocks, configured depending on what the substitution table says and finally a permutation layer follows where all bits are permuted. This procedure is repeated many times until the final outcome is produced. All steps of a substitution permutation network must be reversible in order to be able to decrypt. Specifically for AES, the 128-bits, which are equal to 16-bytes, are handled with the help of a 4X4 matrix with ten repeated rounds to follow. Each element of this matrix is one byte. Each byte comes under the XOR operation with the corresponding round subkey, and then a function is applied in every round that consists of three steps: (1) The Sub-Bytes step, according to which all bytes are replaced with other coming from a look-up table, named Rijndael S-box. This S-box is associated with the Galois Field(28) which is considered to have goo properties. This is a critical operation for the overall structure, as it provides AES with non-linearity. (2) The Shift-Rows step, where the last three rows of the current state are moved some certain positions to the left while the first row remains stable and (3) the Mix-Columns step, where all the bytes of each column of the current state are combined under a linear transformation. The last two steps provide AES with diffusion, a vital property for a secure cipher according to which if we change one bit of the plaintext then almost half of the bits o f the ciphertext will change. It is also considerable that the step Mix-Columns is omitted at the last round of AES. Each subkey is produced by the main key with some kind of expansion similar to the DES. The key expansion is introduced with a number of operations named rotate, Rcon, and S-box and then follows an inner loop in key schedule before the final subkey is produced. 3 Comparison and Attacks 3.1 Running time A real concern about which algorithm is appropriate, especially for commercial use, is the effectiveness and its running time. In general, the larger the block size is, the faster is the algorithm, obviously because larger amount of data is encrypted in one round of operations. Similarly, the smaller the key size is, the faster is the encryption algorithm, because the less key bits are involved in the operations and thus the complexity of them is reduced. A series of experiments have taken place to verify which of the famous encryption algorithms, AES,DES,3DES. Most of these experiments implement these encryption algorithms in Java, although there are some others that used C, most of them at a machine of Pentium 2 or Pentium 4. At most of these experiments, the fastest of these algorithms has been proved to be DES, followed by AES and finally from the 3DES, as it is three times slower than DES. It obviously doesnt make sense to examine the running time of these block ciphers in compl ete isolation with the security that they provide although it is definitely a factor that must be taken into consideration. 3.2 Software and Hardware Implementation Another important aspect that must be examined is the performance of these block ciphers in combination with the available hardware. Again, a lot of study has been carried out and provide us with some clear evidence. In compact architecture, 3DES, DES and AES have displayed very similar performance. In contrast, in high-speed architecture, AES is considered to be almost 4-times than the 3DES and DES. This is happening due to a variety of reasons, amongst them there is no hardware support for DES in modern CPUs, when from the other side there is for AES in increasingly many CPUs, including most targeting servers; hence hardware DES is oà ¯Ã‚ ¬Ã¢â‚¬Å¾oaded to a distant IC, when AES is often in-core. Additionally, DES is often used in CBC mode which makes parallelization inevitable and processed in advance during encryption when AES is mainly used in CTR mode where the possibility of parallelization is available. Finally, DES, and its expansion 3DES is much slower in software than AES, obviously because it was designed back at 1976 before the 8086 processor was designed and uses a lot of bit operations that are not implemented suà ¯Ã‚ ¬Ã†â€™ciently in a processor with a word oriented instruction set. 3.3 Attacks on DES and 3DES As already mentioned earlier at this paper, 2DES has been collapsed from the meet-in-the-middle-attack. Simultaneously, DES, despite its contribution to the overall development of cryptography, has also been defeated by a quite popular attack named exhaustive search. Exhaustive search means that the attacker will search the whole key space and he will find the appropriate, which is unique, in suà ¯Ã‚ ¬Ã†â€™cient amount of time. There are some cases, even in the real world where the attacker can obtain some pairs (mi,ci), where m denotes a message and c the corresponding ciphertext. Under this small requirement, DES was badly broken. To be specific, a company named RSA, back at 1997 announced a problem with the name DES challenge. The company announced six ciphertexts and in parallel announced the first three actual messages and asked for the scientific community to search for the key and use it to obtain the other messages. The same year of the request the challenge had been solved. To go further, the rapid hardware  development was able to create a machine that find the key and solve the problem, equivalently crack DES, within less than one day at the year 1999 with exhaustive search, leading to the assumption that 56-bits length block ciphers should not be used any more. As DES is one of the most famous and controversial block ciphers, it is not entirely surprising that there is a variety of attacks developed against DES, some of them even faster than exhaustive search. Back at 1998, Kocher and Jun demonstrated a very innovative idea by making a side channel attack, introducing a new era for cryptography. Side channels attacks extract information from the physical implementation of the cipher. This type of attack was specifically against smart cards, and is based in power measurement. They actually measured precisely the running time of the smart cards and analysed the diagrams that they obtain from this measurement. In this way, they were able to learn wa s much time was consumed by in each operation from the smart card and find exactly the key. Nowadays, even smart cards are equipped with mechanisms that dont reveal any information of the power consumption there is an attack called differential power analysis, which can steal the secret key after running a lot of time the smart card. It should me mentioned that these attacks are quite general and not for smart cards. In addition, there is another type of a quite highly surprising class of attacks called fault attacks. In this occasion, the attacker can cause a malfunction to a mechanism, lets say to a smart card, for example by warming it up. If he manage to cause and recognise an error at the last round of DES he will be able to discover the secret key. The last attack that we would like to point out is the so called linear cryptanalysis. This is a generic attack and was introduced by Matsui at 1993 and is one of the most realistic, sophisticated and quick attacks on the DES. His a ttacks, and generally in linear cryptanalysis, one tries to find probalistic linear relations between the plaintext, the ciphertext and the secret key. He starts by examining linear relations at the S-boxes of one round and if he succeeds, he will use the to find out linear relations in one-round and then finally them iteratively to find multi-round relations. These relations from round to round are not independent. By combining all these linear relations, the attacker should be able to retrive the secret key. Matsui attack used 244 known plaintexts to find 13 bits of the secret key with a high probability . A similar method was applied to find another 13 bits and then for the remaining 30-bits he applied exhaustive search, he applied exhaustive search, reducing significantly the time that the initial exhaustive search demands. Today, linear cryptanalysis is considered to be, with some improvements, one of the most powerful attacks on DES. Although DES is considered to be faultless and no specific technical vulnerabilities has been found, a high level of linearity at the fifth box of DES has created the possibility for someone to generate this type of attack. Most of the previously referred attacks can also be implemented against 3DES, as the two block ciphers are obviously, highly related. To begin with, an exhaustive search is not suà ¯Ã‚ ¬Ã†â€™cient any more as the key space, if we use three totally independent keys, is huge, especially if we take into consideration the computational power that a strong mahine can demonstrate nowadays. The meet-in-the middle-attack can be applied in a very similar mode, as the attacker can still create a sorted table with the first implementation of DES between one element of the table and the implementation of twice the DES at the opposite direction. The time needed for this attack is 2112, which is considered to be a high level of security, as nowadays a satisfactory level of security against a certain attack is approximately 290, although is still faster in comparison with exhaustive search. Lately, a new attack against block ciphers has been displayed, mainly intended against 3DES and Blowfish and exploits well known kind of vulnerabilities like collision and birthday attacks. Since this is currently under examination and was published only this year, we are not going to expand more. Overall, till today there is not a known and widely acceptable attack that cracks 3DES in a reasonable amount of time. 3.4 Attacks on AES Rijndael has outplayed all other candidates suggested for the AES and so has been analysed quite a bit the last decade. A lot of attacks have been introduced although none of them has hurt AESs security significantly. To begin with, there is a lot of analysis around the meet-in-the-middle attack and some possible improvements of it over the last five years. Gilbert and Minier have proved a very interesting distinguishing property for the first four rounds of AES with the following proposition; lets consider a set of 256 plaintexts where the entry a11 takes all byte values between 0 and 255 exactly once over a given set of plaintexts and all other entries are equal to a constant. If we encrypt this set with three rounds of AES then the function that maps a11 to C11 is determind by 9 fixed 1-byte parameters. C11 denotes the byte values at row i, column j. This proposition was used by them to implement the same idea of the meet-in-the-middle attack. Some further investigation have shown that the number of the parameters, and specifically for 13 or 14 bytes, and this is able to be reduced so the number of the required plaintexts will be minimized. Another famous class of attacks are called cache attacks. Cache is a small part of high speed memory and it aims to keep the CPU as much busy as possible. The catch parameters influence the running time of an algorithm. Specifically, when an element of a data array is called, then we have two possible outcomes. Id the element lies n the cache memory,then the access is instant. In a different situation, the element must be accessed from the main memory. This operation will be executed in significantly different running times and reveal valuable information. We can separate this class of attacks into three families; cold start misses, which arise for the first reference of the data, capacity misses which the magnitude of the element is bigger than the size o the cache and the conflict misses, which may happen in the case of accessing recently accessed data. 4 Conclusion In this paper we examined the structure of popular block ciphers that heavily influenced the development of Cryptography, like DES,3DES and AES and we have compared them in means of running time and software and hardware implementation. We have also considered some basic attacks that have been applied on these cryptosystems. We come to the conclusion that AES is the most safe and practical block ciphers, and this is justified by the fact that is has been chosen for encryption at a series of important applications nowadays. IS it estimated that AES will fully replace 3DES until 2030. There is not any doubt that AES is the most practical and convenient cipher from a hardware and running time perspective. Nevertheless, further investigation must definitely be carried out to ensure the the safety of AES, especially under the increasing enhancement of the technological means, is guaranteed. Finally, the attack Sweet32 is a newly invented attack and must carefully be examined, mainly becau se it is really compromise 3DES security, countermeasures must be taken DES will fully replaced by AES. 5 References [1] Dan Boneh and Victor Shoup, A Graduate Course of Cryptography, August 2015.

Stability for the Children Leaving the Foster Care System Essay

Twenty four thousand children each year age out of the foster care system (Fowler, Toro and Miles 1454). Of that number about half of them are African American, followed by Caucasian and then the other minorities. There are many problems facing these children that are placed in the foster care system. Of course the obvious is that they need a place to live while they are under the age of eighteen also that they need love and support from the people that are around them. Another little known problem is that these youths face once they leave the foster care system many find themselves without a permanent housing, housing that they can finally say that it is there’s and no one is going to take away from them. This paper will cover over why this is a problem for them and some ideas from which we can try to make some changes for the better. For years we have had a need to find housing for children that did not have any place to turn to. In recent years our country has taken up the slack for doing this very thing. In the past these children were seen after by mostly Catholic orphanages forced into hard labor and even had to beg for the money, also called alms, so that they could have necessities. These places were run by the priest and nuns that lived on the premises. Often these children had little food schooling or clothing to call their own. The orphanage that was in Galveston in the early 1900s was run by 3 nuns and 2 priest to the 90 children that were housed their. Obviously these children received very little quality time with any adult figure. Now a days it has gotten a little better, while they do not have many orphanages any more and they have been replaced with foster homes. Youths get more one on on... ...ouses than any other race in America. This has to have contributed to the high numbers of African Americans in the penal system. There absolutely need to be some more cultural sensitivity awareness training on the part of not only the Social Workers that make the determination to remove these children from their homes, but also on the part of the government that oversee these different agencies so that this overrepresentation of this certain population will be reduced. The steps needed are classes that will make these workers more aware of what to expect upon entering these homes and how the people that they encounter my be different and how to decipher with more accuracy if the children really are in life threatening danger. All of these this will contribute to the overall mental and physical well being of these children entering and exiting the foster care system.

Essay --

Furniture design is particularly dependent on trends. During a period of time, the design or general appearances of furniture design changes over the course of history which was influenced by architectural style. Therefore, there are many different types of furniture design available in the market nowadays including wall kitchen cabinets. Most wall cabinets are simply for storage but nowadays, people require durable, sturdy, long lasting yet affordable furniture with improved functionality. At present, in order to have the above mentioned qualities dictated by changing customer demand it is necessary to develop new types of furniture with improved functionality. The desire in furniture style to create new designs or different appearances led to the development of new manufacturing methods and materials used. The design and material of furniture have to meet the customer and manufacturer requirements (Petutschingg & Ebner, 2005). Kitchen cabinet is among the most important items for a home. Cabinets are available in many varieties of styles and design and are mainly used for storage...

The Legalization of Marijuana

There are many reasons why It should be legal. This essay will focus mostly on the medical benefits, but will also compare marl]nana to other drugs, as you can see with this table that marijuana is less toxic than compared to other drugs such as alcohol and prescription drugs. According to this table it is about as toxic and dangerous as caffeine. (Winnfield, 1994) Consuming alcohol excessively is the third leading preventable cause of death In the United States and can really damage the liver, yet this substance Is legal to consume In the United States.Take into the consideration that there are many accidents due to drunk driving or driving under the influence. There is little evidence that cannabis that is used long term causes permanent damage. Lung cancer can be prevented by using a vaporizer.

All drugs do have side effects but with marijuana the dangers are far less. It is used to treat nausea, vomiting, insomnia, lack of appetite, movement disorders, pain, cancer, alcohol abuse, bipolar disorder, inflammatory bowel disease and a host of other symptoms. With stress marijuana helps calm people down and not dwell on problems that they have, while the problems do not go away it is considered to help cope with the problems.Finding the balance to deal with your problems and have marijuana help cope is key to making the use successful.

In this publication random volunteers were assigned to smoke marijuana or identical placebo cigarettes three times daily for 5 days. The report stated that the percentage f subject s who smoked reported more than a 30% reduction in pain intensity, the study found that marijuana reduced daily pain by an average of 34% (Cohen, 2009).Even in friends and family that I have talked to also reported that this is true, that smoking marijuana has helped them deal with pain. They also stated that it has helped keep them calm and would rather smoke marijuana then drink alcohol.
