History of Paper Clips free essay sample
The fastening of papers has been historical referenced to as early as the 13th century, when people put ribbon through parallel incisions in the upper left hand corner of pages. Later people started to wax the ribbons to make them stronger and easier to undo and redo. This was the way people clipped papers together for the next six hundred years. In 1835, a New York physician named John Ireland Howe invented a machine for mass producing straight pins. Straight pins then became a popular way to fasten papers together, although they were not originally designed for that purpose. Straight pins were designed to be used in sewing and tailoring, to temporally fasten cloth together. Johan Vaaler, a Norwegian inventor with a degree in electronics, science and mathematics, invented the paperclip in 1899. He received a patent for his design from Germany in 1899, since Norway had no patent laws at that time. Johan Vaaler was an employee at a local invention office when he invented the paperclip.

Johan Vaaler was the first person to patent a paperclip design, although other unpatented designs might have existed first. American inventor, Cornelius J. Brosnan filed for an American patent for a paperclip in 1900. He called his invention the Konaclip. But it was a company called the Gem Manufacturing Ltd. f England who first designed the double oval shaped standard looking paperclip. This familiar and famous paperclip, was and still is referred to as the Gem clip. William Middlebrook, of Waterbury, Connecticut, patented a machine for making paper clips of the Gem design in 1899. The Gem paperclip was never patented. People have been re-inventing the paperclip over and over again. The designs that have been the most successful are the Gem with its double oval shape, the Non-Skid which held in place well, the Ideal used for thick wads of paper, and the Owl the paperclip that did not get tangled up with other paperclips.

Influential Identity essays
Influential Identity essays Living in a prejudiced country, moving back and forth from slow country life; Arkansas, to a fast pace society; St. Louis, being pregnant at 16 are some of the many problems Maya faced with as an African American teenager. The book, I Know Why The Caged Bird Sings by Maya Angelou is an autobiography, which portrays Mayas life as an African American teenager and gives us an insight on southern life during the 1930s. The book is a recollection of her childhood years with Bailey, grandmother Henderson momma, and her friend Louise Kendrick and how their personalities influenced her to beget her own identity. The first of the three characters is Louis Kendrick. Louis was Maya's first friend. Maya describes her as: "Her face, which was long and dark chocolate brown, had a thin sheet of sadness over it, as light but as permanent as the viewing gauze on a coffin. And her eyes, which I thought her best feature, shifted quickly as if what they sought had just a second before eluded her. She had come near and the spotted light through the trees fell on her face. I had never noticed before, but she looked exactly like Bailey. Her hair was "good" more straight than kinky and her features had the regularity of objects placed by a careful hand". (pg.140) Louis, according to Mayas description is the total opposite of Maya. When Maya and Louis first meet each other they are shy, however as they get to know each other they became best friends. She says "In daring to challenge the unknown with me, she became my first friend" (page 142). Louis influenced Maya greatly as she gave her a chance to be a girl. On page 142 Maya says: " Since all the other children spoke Pig Latin, we were superior because Tut was hard to speak and even hard to understand. At last I began to comprehend what girls giggled about. Louise would rattle a few sentences to me in the unintelligible Tu ...

History and Revolutions Essay Example | Topics and Well Written Essays - 1000 words
History and Revolutions - Essay Example Historical events, properly understood, should therefore enlighten not only in terms of the chronology of particular events, but on the impact a particular event had both in the local history of a particular society, and the wider world history of the human race. Revolutions, like other historical phenomenon, are no different. As John Gates suggests, given the countless studies and surveys regarding revolutions, a proper historical understanding of the phenomenon assumes that revolutions "evolve[s] over time, changing as a result of changes in the political, social, and economic circumstances" in which they develop in, must be fully understood (1986, p. 535). Thus, in illustrating the historical importance of revolutions, this essay will argue that revolutions, as an historical phenomenon, is a crucial process that contributed to the emergence and consolidation of the modern world by altering a society's political, economic, and social structures at the local level, and consequently introducing new ideas, institutions, and ideals for the world in the international level. Revolutions have always been associated with change. According to Huntington1, (1968) it is a modernizing concept resulting to political modernization and development (p. 265). He argues that they are most likely to occur in societies that experienced "some social and economic development" where "political modernization and political development have lagged behind the processes of social and economic change," limiting the phenomenon to transitional states, which are neither highly traditional nor highly modern (Huntington, 1968, p. 265). Thus, Huntington makes the distinction between Western revolutions in France and Russia from Eastern revolutions in China and Vietnam based on the type of old regimes. On the other hand, in Barrington Moore's Social Origins of Dictatorship and Democracy, he distinguishes between three types of modernization processes2 different societies underwent through revolutions (Zagorin, 1973, pp. 39-40). Both typologies present an important aspect of revolutions - they presented revolutions in light of the modernizing process it is part of. As both scholars argue, revolutions bring about modernization, however, the degree and type of modernization and development following a revolution are contingent on the type of regime preceding it and the manner that the revolution took place. Thus, Moore situates revolutions as a "decisive point of conflict" in the historical process that yields important systemic consequences determining the type of institutions that emerge after the revolutionary stage (Zagorin, 1973, p. 40). This concept of revolution echoes the proper historical understanding of revolutions through time. By treating revolutions as more than just a separate event at some point in time, but as a point within the continuum of world history, a better understanding of the phenomenon's larger historical value is achieved. In this case, "the significance of the French revolution in world history lies in its having with a powerful blast cleared the way for a new era in the life of continental Europe" (Elbaki, 1976, p. 218). Considering the immediate outcomes of the French revolution of 1789 one can see minimal improvements in the industrial and

Privatization of zain company in kuwait Assignment
Privatization of zain company in kuwait - Assignment Example Getting hold of all the board members to assist in making key decisions was difficult since they also had other government duties assigned to them. The research findings also revealed that Zainââ¬â¢s services changed after its privatization. When comparing Zainââ¬â¢s services between pre and post privatization, the study revealed that the level of satisfaction due to service and product increased. The several categories of service delivery evaluated included: communication to the clients, monthly billing, branches availability and working hours, and the time for service delivery whether it is new subscription or reactivation of the service. The results revealed that the services before privatization were basic.

The varied products and servi ces brought about by Zainââ¬â¢s privatization were registered in its profits. Some of potential weaknesses experienced during the study that were not within the control of the researchers included time constraints, small number of participants and lack of pre-privatization company sources. As regards to time; time frame allocated for the entire study was not enough to enable the researcher interview all the respondents. The set time was limited; thus, it was difficult for the researchers to meet the employees and the customers, some of which have busy schedules. Secondly, the sample population chosen for the research was small compared to the entire number of Zainââ¬â¢s customers and employees. Lastly, before privatization; the company was owned by the government and was not listed in Kuwait stock Exchange market. Therefore, to access data and get information on the strategy

Workplace of tomorrow Essay Example | Topics and Well Written Essays - 1250 words
Workplace of tomorrow - Essay Example Malone in his book, The Future Arrived Yesterday, has given a good introduction to the workplace of the future and has shown the way to build tomorrowââ¬â¢s workplace. He describes the changing paradigm and shows the way as to how companies can build the workplace of the future by innovation, nimbleness and an ability to adapt to rapidly changing trends. He has characterized the workplace of tomorrow as a nimble ever changing entity that adapts itself to new trends and provides challenges to the employees in terms of the work that they do as well as making them intellectually and emotionally fulfilling. The need of the hour is to provide employees with intellectual challenges and emotional fulfillment. To quote from the book about the workplace of tomorrow, ââ¬Å"What I am talking about is the kind of tough-minded leadership that sees people-oriented management as a competitive advantage, one that increases productivity and innovation, reduces turnover, and makes the company less vulnerable to market shifts and to competitive shocks. This is management that fulfills the spiritual, emotional, and moral needs of subordinates not because it is inherently decent (though that is certainly the grounding for these actions), but because it makes the organization they inhabit more effective. This is the kind of pragmatic leadership that historically has been found in the best managed and most admired organizations, from Hewlett-Packard and IBM a half-century ago to Grameen Bank and Google today. These firms are inevitably admired for their innovation, their employee policies and work envir onments, and their contributions to society, but what they should be celebrated for most is their recognition that the secret to building an unbeatable, world-class enterprise lies in understanding not just the heads, but the hearts, of their employees and customersâ⬠. (Malone, 2009) As the above paragraph shows, the workplace of tomorrow would be characterized by flexibility

The Study Of Human Computer Interaction
The Study Of Human Computer Interaction Human-computer interaction (HCI) is the study of interaction between people or users and computers. It is often regarded as the intersection of design, computer science and several other fields of study. Interaction between users and computers occurs at user interface or simply interface. This includes both hardware and software such as object or characters are display by software on a personal computers monitor. The inputs receive from users via hardware peripherals. For example keyboard, mice. Human-computer interaction (HCI) studies a human and a machine in conjunction. It draws from supporting knowledge on both the machine and the human side. On the machine side which techniques in operating system, programming language, computer graphics and development environment are relevant. Other, the human side have communication theory, graphic and industrial design disciplines, social science, linguistics, cognitive psychology and human factors are relevant. Human-computer interaction (HCI) is a wide discipline which studies all the elements linked to the human use of computer and software by association. It also concerns devices which can be linked to computer such as mobile devices, computerized consoles and video terminals. The main aim of Human-computer interaction (HCI) is to make the use of software and computerized devices as simply and easy to understand as possible which with the aim of improving the efficiency and effectiveness of the action taken at the same time. Human-computer interaction (HCI) covers all the main stage of the productive flow from design of the user interface to the investigation of the result obtained, passing via the search for innovative solutions and the laboratory assessment of prototypes. This is another reason why Human-computer interaction (HCI) involves aspects linked to a number of disciplines, including: Your password is what tells the computer that you are who you say you are. Until we can do retina scans like in James Bond movies, the password is the best that we can do. But, because your password is like a key to your account, you need to safeguard it. Anyone who has your password can get into your account, and your files. Anyone who can guess your password has it. Anyone who has your password can pose as you. Therefore, you may be held responsible for someone elses actions, if they are able to get your password. You may not wish this to happen. Tips on safeguarding your password First and foremost, NEVER give your password to anyone. Anyone means your coworkers, your spouse, your systems administrator. In the event of an emergency, the sysadmin can change your password. Your sytems administrator never has a need to know your personal password. If someone needs to get onto our machines, and has a reason to be here, do not give them access to your account. Speak to the systems staff about us setting up an account for them. We would be very happy to give them one. Make your password something you can remember. Do not write it down. If you really, honestly forget your password, we can easily give you a new one. Wed rather set your password once a month because you forgot it than have someone find it written down and gain unauthorized access to your account. Make your password difficult for others to guess. This is not as hard as it initially seems. See the section below on chosing a good password. DO NOT Change your password because of mail from someone claiming to be your systems administrator, supposedly needing access to your files!! This is a popular scam in some circles. Remember, your systems administrator never needs your password for any reason. If someone needs to ask you to change your password so that they can gain entry to your account, they do not have reason to be there. We run sophisticated password crackers on the password files of our machines. If we guess your password, you will have to come see a staffer to have it changed. These are the same crackers that the bad guys have access to, so if you have a weak password, its better if we find out about it first. How Not to Choose a Password Here are some of the types of passwords that will be picked up by our crackers: Words in the dictionary. Words in any dictionary. Your user name. Your real name. Your spouses name. Anyones name (crackers dont necessarily know that your aunts middle name is Agnes, but its easy enough to get a list of 100,000 names and try each one). Any word in any cracking dictionary. There are lists of words that crackers use to try to crack passwords: passwords that a lot of people use. Some of these lists include: Abbreviations, Asteroids, Biology, Cartoons, Character Patterns, Machine names, famous names, female names, Bible, male names, Movies, Myths-legends, Number Patterns, Short Phrases, Places, Science Fiction, Shakespeare, Songs, Sports, Surnames Any of the above, with a single character before or after it (8dinner, happy1). Any of the above, capitalized (cat > Cat) Any of the above, reversed (cat > tac), doubled (cat > catcat) or mirrored (cat > cattac). We used to tell people that taking a word and substituting some characters (a 0 (zero) for an o, or a 1 for an l) made a good password. This is no longer the case. New crackers have the capability to crack things like this, in certain situations. Words like foobar, xyzzy and qwerty are still just plain words. They are also popular passwords, and the crack programs look for them. Avoid them. Any of the sample passwords, good or bad, mentioned in this document. How to Choose a Good Password I know that coming up with a good password can be difficult, so here are some guidelines to use. Choose a password that is at least six characters long. This should be long enough to discourage a brute-force attack. Currently, the maximum password length on many Unix systems is eight characters, but if you want to add a few more characters to make it easier to remember, go ahead. Just bear in mind that anything after the eighth character will be ignored (so abnormalbrain is the same as abnormal). In general, a good password will have a mix of lower- and upper-case characters, numbers, and punctuation marks, and should be at least 6 characters long. Unfortunately, passwords like this are often hard to remember and result in people writing them down. Do not write your passwords down! At work, your network people will require you to change your password every several days. At home, you should rotate your passwords as a matter of good computer hygiene. If you are using different passwords for differents websites, you can do yourself a favor by rotating portions your passwords every few weeks. Note that rotating parts of the password, not the entire passwords, will help deter hackers from stealing your phrases. If you can memorize three or more passwords at the same time, then you are in good shape to resist brute force hacker attacks. My conclusion is The graphical password schemes we considered in this study have the property that the space of passwords can be exhaustively searched in short order if an offline search is possible. So, any use of these schemes requires that guesses be mediated and confirmed by a trusted online system. In such scenarios, we believe that our study is the first to quantify factors relevant to the security of user-chosen graphical passwords. I recommendation that every month change one time password for safe. All security things dont let anyone know. Special security question. Because security question is help user find back forget password. character and number mix together is a best password.

A Piece Of My Heart (book) :: essays research papers
The "other" Vietnam Vets Everybody knows about the men who served in Vietnam. They have at least heard of the mentally trying conditions during the war and the resulting "post traumatic stress syndrome" (PTSD) so many veterans suffered from, or heard of the issues concerning negative public opinion of veterans for their role in a hated war. However, few are aware of the female role in the Vietnam War; women, the "other" veterans, shared in all of these problems and issues along with the gun-toting men. They were the nurses, and in A Piece of My Heart by Keith Walker the stories of many women are presented to better understand just how the Vietnam War affected women. Working in places like evacuation hospitals exposed women to the endless flow of casualties from the battlefield, and these experiences took major mental tolls upon the minds of the women who had to assist them, especially in their considerations for the value of human life. Women experienced other problems upon returning home such as the same PTSD and outlashes by anti-war protesters. Women were veterans of Vietnam just like the men, and they experienced many of the same problems as a result of their role there. Women were exposed to an enormous amount of pain while in Vietnam. As veteran Rose Sandecki said, "[The Vietnam] War really did a number on all of us, the women as well as the men" (20). Nurses in Vietnam were exposed to a nonstop flow of casualties from the field. The landing of a Chinook with mass casualties on board had become a standard to Christine Schneider, a nurse in Da Nang. Practically every nurse’s story described the hospital scenes in Vietnam as "busy." Jill Mishkel explained that she experienced a minimum of at least one death per day. As Ms. Schneider described, "There was just too much death" (46). Ms. Schneider also mentioned, "Everybody was bad" (45); nurses only saw the bad because they were surrounded by it, day in and day out. Charlotte Miller described everything as "on a very negative basis" (324), and that she had to deal with these problems from twelve to fifteen hours per day, twelve to fifteen days in a row, a very rigorous schedule. Further emotional damage was incurred by the severity of the injuries that the nurses had to deal with. Nurses described situations such as little boys with their intestines hanging out, men with half their faces blown off, men missing their legs from a grenade explosion, paraplegics, quadriplegics, and in one case pulling someone’s shoe off and having the foot come with it.
