My Trip to America Essay

The plane was taking off. Gravity pulled me lean on the back of the seat. Seeing the trees, roads, cars and buildings became more and more blurry in my sight, I felt my brain was blank. â€Å"Hey, I’m really going to leave tomorrow†¦Ã¢â‚¬  I called my best friend the night before I left. â€Å"Don’t forget to swim across the Pacific Ocean to visit me. † She said after the long silence. Yes, for me at that time, America was truly just Hollywood and Disneyland on the other side of the Pacific Ocean. But soon enough, I would find out the real America by myself. Before I knew, I was already breathing the air of San Francisco, my first stop. The Hip-Hop music coming from the radio was really loud, and people were trotting. I could even feel the fast beat of that city in the car. Something was not in that rush though — the pigeons. They were taking a walk leisurely on the street, did not afraid of people, as though if the hurry did not belong to them at all. That scene was never to be seen in my country. When the last piece of furniture was moved into my apartment, my dad signed: â€Å"we have a home in America now. † â€Å"chicago il. † In the first summer, I used to touch the unacquainted address on the envelope every time we got letters, practiced to recite telephone number and close my eyes to feel the wind. So my new life just had begun unconsciously. Almost nothing fitted what I imagined about the High School. Because it was a lot better than what I supposed. I thought I would be lonely, no one would talk to me, but actually at the end of the first of school, I already had known someone who I could consider as friend. Things were indeed not easy though. I held the map of the school building, and finally found my way to classroom after asking three people for direction. Teachers were nothing like the strict teacher in China, they were patient and funny. They were willing to be students’ friends. I used to say, â€Å"Sorry, my English is very bad. at the beginning of the school year every time when I finished talking with someone. Once I was sitting outside of school gate on the stairs and talking to a girl, when I said my formal conclusion sentence, she said â€Å"Oh no, your English is very good! † and gave me a shinny smile. In my memory, the sky of that afternoon was as limpid as a lake with glittering sunshine†¦ Honestly, I did not understand or feel much every morning when we put our right hand on the left chest and say the oath towards the flag. Until one day the school showed the commemoration of 9. 11 on the TV, I saw many teacher cried. I suddenly realized that America is their home, was just like someone attacked their home and hurt their sister or brother. The oath to the Stars and Stripes is not just about a verb, a pose; it’s about the feeling of home. Most sunny days of chicago are mild. I will sit in front of the desk and look up to those cotton-candy-like clouds through the window. Or I will always take a walk in the dusk on some clean and quiet bypath, the tip of the church, which is tinged by the orange afterglow and the tall Chinars along the path, which sings softly in the wind, always make me think I have crashed in to a fairyland. I know that I felt and still feel the love when I was singing the national anthem of my country, China. And America is where I live and study now. It is my second home. I am getting the excellent education here, I have met lovely and patriotic people here, and I have seen the charming scene here. I am experiencing a totally different lifestyle here. Close my eyes, I still can see the tears on my grandparents’ face in the airport; I can still smell the thick Natee on every street of San Francisco; I can still remember once there was a girl who was too nervous to decide whether to wear a pink or white T-shirt on the first day of school. After a year and a half living in America, I’m still that happy little girl, except when I think about America, it is not more far away across the Pacific Ocean, it is where my new life is, it is my home. And another thing is that I can be the person to show others the direction to the classroom now.

IT security and Control

IT security and Control According to Hawker (151), IT Security and Control include physical, logical and administrative measures organizations put in place to ensure data integrity, confidentiality, and availability to authorized users. Information system avail data to authorized users through validation and verification procedures. In addition, data integrity standards should be enforced when data is being transmitted to prevent it from unauthorized access, intentional or accidental modifications, or malicious damage.Advertising We will write a custom essay sample on IT security and Control specifically for you for only $16.05 $11/page Learn More Comprehensive approaches subject organizations’ information systems to regular security checks in addition to system audits (Peltier 2). Regular system audits ensure that responsible organizational managers are able to track users and establish any potential sources of malicious attacks or unauthorized access. These measures are im plemented within and outside organizational boundaries. Organizations benefit from IT Security and Controls by integrating and aligning them to organizational goals and objectives. Peltier (1) argues that organizations have defined standards, policies, and procedures for implementing security measures and controls to prevent data loss or damage. Information can be sold or mined to enable radical decisions to be made. Peltier (2) argues that users should form informed decisions on system usage when login sessions commence and should be made aware that they are being monitored. Peltier (11) asserts that security and control measures such as firewalls implemented at different levels, risk analysis, encryption of data using different techniques, e-mail and other communication policies ensure that organizational information is kept confidential and made available to the intended parties. Firewalls filter outgoing and incoming data to ensure no corrupt data, or malicious software or compu ter programs accesses an organization’s information system. Organizations impose administrative controls on data, which is a valued asset, at different levels to ensure accountability and responsibility for system users. This may include passwords verifications and access rights’ mechanisms. Data integrity is maintained organization-wise.Advertising Looking for essay on it? Let's see if we can help you!

An organization may not be at risk of loosing sensitive information to the outside when software is installed to control access to information in addition to implementation of access privileges to system users. Organizations benefit from the use of physical controls by enforcing policies such as the use of cameras and clear definition of duties. Thus organizational activities are monitored to avoid potential incidents and threat s to data corruption, espionage, and damage. Information is a valuable asset to any organization. It should be managed well. Gertz, Guldentops, and Strous (27) asserts that the movement of traffic in both directions enables a system performance evaluator to determine the vulnerability of system components and controls. Such performance measures can also be evaluated against the policies and objectives of an organization. Deviations from established benchmarks determine the degree to which performance of the information security controls are effective (Gertz, Guldentops, and Strous 57). Other measures include the use of software tools to evaluate performance standards of networked computer systems in addition to conducting tests to evaluate effectiveness of system security. A performance evaluation plan is developed by an organization and tests conducted against benchmarks to identify security loop holes. Information security and controls should be embedded in an organization’ s culture at personal and organizational levels. Tests should be consistent with organizational, management security control goals, and objectives (Gallegos, Senft, Manson, Daniel and Gonzales, 124).

Explain the differences between a group and a team Essay

Explain the differences between a group and a team - Essay Example To describe it briefly, it will be suffice to say that all teams are form of work group but not all groups are teams. There are several fundamental principles that distinguish the two. First is accountability. In groups, members are individually accountable within the group; they have to be alert from people within the group. In teams, however, individual accountability does exist but on a minimum level; teams are accountable mutually. Instead of reporting to one another or someone from amongst group, teams report to a higher authority. This means that teams are more united and open with each other. This also highlights the fact that usually groups work on lower levels while teams work at higher, more independent level in the hierarchy (Thornton, 2010). Secondly, members working in the group meet regularly to circulate information and discuss perspectives whereas team members just meet occasionally to make decision, plan, and solve any problems that arise in a meanwhile. This implies that team member share more trust than group members do, making them more self-reliant and confident of their own actions. Thirdly, group members work on individual goals while team members work on mutual goals. This shows more unity and togetherness that is shared by people working in the team. For instance, people in groups may work hard for promotion/to please their supervisors/ in order to get a pay upgrade but team members will worry less about such petty matters and try to get bigger tasks done. Fourthly, groups focus more on individual products while teams emphasize more on team products. Instead of getting their names high like in groups, team members focus more on efficiency and excellence, making merit the parameter for judgment. Next, groups have defined roles and responsibilities whereas team members are more liberal with these lines and feel free to share each other’s work. Lastly, in groups, manager, with little say from members, shapes the goals and tasks desi gned to achieve them. On the contrary, team leader brings the whole team together to shape the goals and delegate tasks on each member with their complete will. This gives a sense of ownership to the goal and creates a free environment where learning and creativity thrives (Levi, 2010). As the world is coming together to form a global village, it is important to embrace, appreciate and celebrate the diversity, which flourishes as people from across the world come together to accomplish goals of mutual interest. However, diversity is tough to handle since it requires a lot of compromise and patience to settle down with. Nonetheless, importance of diversity cannot be over-emphasized. With people from different backgrounds, religious views, ethnicities, social status, and education coming together on a common platform, the ideas generated, and discussions held are more multi-lateral and creative. In addition, the solutions found with diverse bodied thing tank are applicable to more tha n a single thinkers and work in more than a few conditions since its planners have put together their own personal experience in planning and critiquing it, refining into more applicable and garnishes the concept. On the other hand,

Ehtno-Drama (Drama Creation) Paper Baed on ELL(English Language Term

Ehtno-Drama (Drama Creation) Baed on ELL(English Language Learner) Interview - Term Paper Example He had to Google maps to know where to go and master the Google directions keenly not to get lost. This was because the one who brought him to America went back immediately because of problems that arose immediately after they took off from the Airport. On asking him on the initial difficulties he faced in America he said that he had problems in the English language which posed a barrier in communication. He describes an incident when he developed health issues and reported to the hospital in New Jersey. He was unable completely to communicate with the nurse at the reception. This made the nurse to confront him with a racist language. Telling him, â€Å"You immigrant why come to America and you do not know how to speak English?† Do you think we are terrorists like you? This he said made him to give up on the medication and go home. Lucky enough the health complication healed after some days without ant treatment. He further told me that from that day he enrolled for English lessons at a certain college in New Jersey so that in the future he could not face other discriminative encounters like that. He even stopped wearing his Arab clothes and wore like Americans to conceal identity on suspecting eyes. Further, on the question of a facing a different culture and how he overcome it he told me that despite the cultural differences between Qatar citizens and the Americans he coped well with it. He said that the American foods were different to theirs. Even living styles of the Americans were very different in terms of clothing, entertainment and interactions. He said that he observed that mostly the White Americans despise the Black Americans something that does not happen in Qatar. He said that the Qatar people are so friendly and welcoming to fellow citizens and foreigners. He had no problem with coping with American culture because with time he adjusted very well and become part of the citizens by making of many American friends who taught him

Ratios Tell A story assignment Essay Example | Topics and Well Written Essays - 1250 words

Ratios Tell A story assignment - Essay Example However, it is very difficult for one to examine the whole financial statements of a company. Ratio analysis makes it easier for everyone to understand the profitability, solvency, and efficiency position of the firm. Ratio Analysis is a tool used for quantitative analysis of the information from the financial statement of a company. In spite of the advantages, ratio analysis has several drawbacks too. It consider only historical data, the future performance of the company cannot be predicted. It helps to evaluate firm’s financial status on the basis of past and present financial data of a company. In this study, comparisons of ratios have been made on different companies according to their financial indicators. A ratio analysis has been conducted to compare the profitability, solvency and efficiency of Wal-Mart and Safeway. Ratio analysis helps to effective analysis of the financial statement. The financial status of the companies can be easily understood by the help of the r atio analysis. Safeway vs. Wal-Mart Safeway Inc is a supermarket whereas Wal-Mart is general merchandise. Wal-Mart can also be classified as hypermarket. Hypermarkets are similar to big-box stores. The business of hypermarket is decisive on high volume, and low margin of sales. Wal-Mart is a typical supercenter covers around 150,000 square feet to 235,000 square feet area. It is the combination of supermarket and departmental stores, mainly situated in suburban or out of town locations. More than 2 lac brands can found here. Whereas Supermarket is a store based upon self service. It presents a huge range of food and household merchandise, divided into sectors. The range of foods and products are limited here rather than supermarket. There is a huge difference between the inventories of these two companies. It is because Wal-Mart sells more than 2 lac of different type of products whereas Safeway is limited with its narrow range of food and household products. Net PP&E are almost sam e (60%) in case of both the companies, because both of them are involved in retail business. The cash of Safeway is also less than Wal-Mart is due to the size of the business. Wal-Mart is more capable of generating cash in a higher volume to its variety of products. Adobe vs. Hewlett-Packard Adobe Systems Inc. is a software development company and Hewlett-Packard Company is a computer manufacturing company. In a computer manufacturing company, heavy processes are driven for manufacturing new products. The workers are needed to perform a specific task. After the completion of one task the next task can be performed by the next worker. A software development company includes research, development of new product, prototyping, modification, reuse, re-engineering, and maintains of other activities. Hewlett is having fixed assets near about 2 times higher than Adobe. As Hewlett is a manufacturing company it needs more instruments and equipments than Adobe. In case of both short term and L ong term debt, Adobe has none of these two because it is a service based company. It does not need extra money to run its business. In case of Hewlett the value of both short term and long term debt is higher. As the company runs factories, it needs money from outside to run its business. Amazon vs. Consolidated Edison, INC Amazon.Com is an internet retailer and Edison Inc has its business on electric utility. When a

Why Evolution Is True by Jerry A. Coyne (Penguin Books) Published in Essay

Why Evolution Is True by Jerry A. Coyne (Penguin Books) Published in 2010 - Essay Example These evolution theories contradict with the concept of the creationists. The creation concept says that the human beings are not evolved rather they are created at once and that animals and the human beings are different from their origin. Both the concepts of evolution and the creation are very much opposite to each other. The subject of the book is very important to be clearly understood in our own life. In other words we can also say that â€Å"Why Evolution is true† is the summary of all the facts of Darwin’s evolution theory and also the natural selection process. Natural selection process is explained very well by the Darwin. This means that the one living organisms who strives for the life gets the chance to survive in the competitive environment. With the help of his arguments, Jerry Coyne has showed that the natural selection process do not destroy the beauty of life rather it enhances or give advancement to it in a gradual manner, because the nature itself selects the suitable living beings on its own behalf. The process of natural selection basically means to find out the proper resources to live the life. The one who find out the available resources would be included in the list of the naturally fittest organisms thus striving for saving the life. In other words we can also say that the natural selection means the struggle for the existence. For this struggle the living beings may change their traits and this would be called as the gene variation according to the environment. The changing of traits may help living organisms to grab the best possible resources. This gene variation would help them to survive according to the environmental conditions. Actually each and every individual is composed of different combinations of genes. Some of these genes traits are helpful or other might be less important in the survival. Therefore the individuals may change such kind of traits and also adapting to those which are more

A History of Digital Dignatures

A History of Digital Dignatures History of Digital signatures Whitfield Diffie and also Martin Hellman throughout 1976, were the first that explained the idea of an electronic digital unique structure. It was while they simply conjectured in these kinds of techniques, and quickly after, Ronald Rivest, Adi Shamir, along with Len Adleman conceived the RSA protocol. This could be utilized to create ancient electronic digital signatures. Ddespite the fact that simply being a proof-of-concept, the plain RSA signatures are not secure. The initial extensively advertised software package to provide digital signature had been Lotus. It was introduced throughout 1989, and is usually employed by the RSA algorithm. To make RSA unique tips, create an RSA essential set containing the modulus d thats the product of two large primes. Also imagine the integers: e as well as d such that e d = 1 (mod f(n)) The actual signers general public essential is made of n and also e, and the signers solution key is made up of d. For an indication, there is a communication m, and the sign computes s = md (mod n) To ensure, the receiver checks that s e = m (mod n). While noted before, this kind of basic structure just isnt really protected. In order to avoid episodes, one can very first, and then can implement a new cryptographic hash function for the communication m. And then he can apply the RSA formula described previously mentioned to the result. This strategy might be established secure inside so-called arbitrary prediction model. Some other digital camera unique strategies have been quickly created soon after RSA. The primary are Lamport signatures, Merkle signatures (also known as Merkle trees or perhaps Hash trees), and Rabin signatures. Inside 1988, Shafi Goldwasser, Silvio Micali, and Ronald Rivest took over as very first to carefully outline the protection specifications associated with digital trademark strategies. They defined any pecking order regarding attack models regarding unique schemes, and also found the GMR personal structure, the first that can be which may prevent perhaps an existential forgery in opposition to a new chosen information invasion. The majority of early on personal plans had been of the comparable type: they call for conditions trapdoor permutation, such as the RSA perform, or perhaps in true with the Rabin personal system, computing rectangular modulo amalgamated n. A trapdoor permutation family is a family group associated with permutations, particular by a parameter, that is simple to work out inside the forward route, yet is hard in order to figure out inside the invert path with no by now knowing the private essential. Even so, for every parameter there is a trapdoor (exclusive important) that if identified, quickly decrypts what its all about. Trapdoor permutations may very well be public-key security techniques, in which the parameter will be the open public essential and the trapdoor will be the key, and also where encrypting corresponds to computing the particular onward direction of the permutation, whilst decrypting corresponds for the change direction. Trapdoor combining can even be seen as electron ic digital personal schemes, where computing the opposite direction with the entire secret key is thought of as signing, and research the actual forwards course is performed to verify signatures. Because of this messages, electronic digital signatures are often called determined by public-key cryptosystems, in which deciding upon is equivalent to decryption and verification is the same as encrypted shield, however this isnt the only method electronic signatures are usually calculated. Employed immediately, such a unique system is actually at risk of a new key-only existential forgery attack. To make a forgery, the particular attacker choices any haphazard trademark s and uses the confirmation process to look for the communication m equivalent compared to that signature. Used, nevertheless, this sort of unique isnt used right, but alternatively, the material to become signed can be initial hash to generate a short digest thats then closed. This forgery assault next, only generates the actual hash function output which refers to s, and not a message that leads for its benefit (which does not cause an attack). Within the random oracle model, this specific hash-and-decrypt form of unique is existentially un-forgeable, actually in opposition to a chosen-message assault. There are several top reasons to sign this type of hash (or perhaps message absorb) instead of the entire record. For performance: The trademark will probably be much quicker thereby save time considering that hashing is mostly considerably quicker than putting your signature on in practice. For being compatible: Mail messages are normally little bit guitar strings, however, many signature strategies run on other areas (including, in the case of RSA, amounts modulo an amalgamated number n). A new hash perform may be used to convert an haphazard feedback into the appropriate file format. With regard to ethics: Without the hash operate, the words to end up being signed might have to end up being divided (divided) in prevents sufficiently small for your unique system to do something on them straight. Nonetheless, the particular device in the agreed upon blocks is not able to acknowledge if every one of them is present and in the proper get. ADVANTAGES AND DISADVANTAGES OF DIGITAL SIGNATURES The main benefit thing about public-key cryptography can be the increase in security, as well as comfort. This is because the private keys never need to be transported or exposed to any person. In a very secret-key technique as comparison, the secrets recommendations should be carried (both physically and through a conversation station), and there might be a possibility that the opponent could find the secret during their transmitting. Another significant benefit from public-key programs is that they provide one way functions with regard to digital signatures. Validation by the way of using secret-key systems requires only the expressing associate of the key. But sometimes it needs interaction of a third party as well. Therefore, a new mailer can be easily repudiated by a previously authenticated concept. This is through proclaiming how the discussed solution ended up being for some reason affected by the events revealing the secrets. As an example, the particular Kerberos secret-key authentication method consists of a new central repository that maintains replicates in the solution recommendations of most consumers. This way an attack on the databases will allow widespread forgery. Public-key authentication, conversely, stops this sort of repudiation; every single individual offers single obligation regarding safeguarding his / her individual crucial. This particular residence associated with public-key authentic ation is frequently named non-repudiation. A problem with using public-key cryptography pertaining to encryption is actually rate: youll find well-liked secret-key encryption techniques which are drastically more quickly as compared to any kind of available today public-key file encryption strategy. On the other hand, public-key cryptography works extremely well using secret-key cryptography for the greatest involving all possible. For encryption, the very best option would be to combine public- and secret-key methods to achieve the two security benefits of public-key programs and the velocity benefits of secret-key systems. Your public-key technique may be used to defend the key which is used to ensure the bulk of personal files or even communication. Such a process is known as digital camera envelope.. Public-key cryptography may be susceptible to impersonation, nevertheless, even though users exclusive recommendations usually are not obtainable. A successful invasion with a qualifications specialist enables an adversary in order to impersonate anyone the particular adversary selects to by using a public-key qualification from your jeopardized expert to situation an integral in the adversarys option to the category of yet another person. In several conditions, public-key cryptography is not required along with secret-key cryptography on its own is risk. This consists of situations where protected secret-key arrangement may take spot, for example through consumers conference within an individual. It also includes conditions in which a one expert understands and also manages all of the recommendations. As an example, a new closed financial program. Since the management knows everybodys keys already, theres not a lot advantages for it to get public. Furthermore, in public-key cryptography it is normally not needed in single-user surroundings. For instance, if you want to keep the data protected, you can do so with any kind of secret-key file encryption algorithm employing, declare, your individual security password because magic formula essential. Generally, public-key cryptography is best suited with an available multi-user natural environment. Public-key cryptography just isnt meant to exchange secret-key cryptography, but instead to be able to dietary supplement the idea, to restore safer. The initial way of using public-key methods ended up being for risk-free crucial exchange, in the otherwise secret-key system, which is nonetheless among its major capabilities. Secret-key cryptography remains vitally important and is also the subject of a lot continuing review as well as investigation. A few secret-key cryptosystems are usually discussed inside the areas about prevent ciphers along with flow ciphers.
