Information Security Research Paper Example | Topics and Well Written Essays - 1250 words
Information Security - Research Paper Example The progress in the field of information technology has been favorable because it has brought various benefits for the users all around the world. However, along with many significant benefits, the advancement in information technology has also created various issues related to the security of computer networks. These network-related issues need to be tackled properly in order to make the internet world safe and secure. Literature Review regarding Current State of Network Security Kaminsky (2010) asserts, ââ¬Å"Network security comprises the measures a company takes to protect its computer systemâ⬠. It is evident from the above statement that network security deals with the protection of information stored in the computer systems. There are various issues associated with the current state of the network security. Douligeris and Serpanos (2007, p.94) show their concern about network security by saying that current mechanisms of network security do not handle the threat of worm a ttacks properly. Leynes (2010) states, ââ¬Å"Worm is a malicious code or software that spreads from one computer to another using the network highwayâ⬠. ... Maiwald (2004) state that current state of network security cannot be called purely safe from all sorts of threats. Although virus and worm attacks have decreased considerably, yet the companies need to address information theft issue, which is the top network security concern these days (Batten, 2008, p.24). Network administrators also hold the responsibility to create new mechanisms for the security of networks. McFarlane (2010) asserts, ââ¬Å"There is no doubt that network administrators are today dealing with much more sophisticated network and computer security threats than they did a few years agoâ⬠. Network administrators still need to do more in the field of network security. Laet and Schauwers (2005, p.3) state, ââ¬Å"Currently, network administrators often spend more effort protecting their networks than they spend on the actual setupâ⬠. Reaves (2010) in an article states, ââ¬Å"Steps need to be taken to ensure that user access to the network cannot compromise the entire networkâ⬠. Lynn (2009) asserts, ââ¬Å"In today's threat landscape, the most secure network infrastructures implement not a single network security technology, but a multilayered comprehensive security strategyâ⬠. Fundamental Issues and Concerns for Network Security There exist many fundamental issues related to network security, which are of significant importance for the successful advancement in the field of network security. Some of the core fundamental issues include authentication, access types, and authorization. Let us discuss these issues in some detail. Authentication Authentication of the user logging onto a network is one of the fundamental issues related to network security. Biometrics and passwords are generally used to

Cambrian Explosion Research Paper Example | Topics and Well Written Essays - 1500 words - 2
Cambrian Explosion - Research Paper Example Some of the animals with basic animal bodies include arthropods such as insects, crustaceans, and trio-bites, cnidarians like jellyfish and corals, mollusks such as shellfish and squids, echinoderms like sea urchins and sea star, and chordates such as vertebrates. The Cambrian exposition occurred during the Cambrian period that began 570 million years ago and ended 510 million years. According to Meyer et al. (2001), the Cambrian exposition occurred within a window of 20 to 40 million years during the Cambrian period. According to BBC, (2015), the Cambrian period began 545 million years ago and ended 495 million years ago. The Cambrian period was characterized by the sudden emergence of living organisms in the sea. Although geologists are lucky to identify some Cambrian fossils, there was no life on the land. According to Darwinââ¬â¢s theory, the Cambrian exposition is based on the existence of changing environmental conditions that cause genetic modification of genes. The major cause of the Cambrian exposition is believed to be a rapid increase in the oxygen level in the atmosphere. An increase in oxygen level in the atmosphere occurred approximately 2.3 or 3 million years when numerous microorganisms released oxygen to the atmosphere through photosynthesis. The second oxygen increase event occurred approximately one billion years ago and resulted in the development of various complex organisms during the Cambrian period. The link between the increase in oxygen levels and development of complex organisms is confirmed by various past events. For instance, the oxygen concentration is believed to have increased from 10 % to 21% in the past 425 million years. The event resulted in the evolution of vertebrates thus attaining essential features. Secondly, high oxygen concentration level in the atmosphere resulted in an increase in insect size (Koch & Britton, 2009). According to Penumaka (2011), the earth was covered by glacier 580 million years ago thus
Questions and Answers on Family and Consumer Science Assignment
Questions and Answers on Family and Consumer Science - Assignment Example 2. What are assumptions in the scientific sense? An assumption, in the scientific sense, is a working hypothesis. Before going on with the experimentation, people usually make assumptions first to form a specific structure of an idea. Assumptions are usually several before an experiment begins, and gets reduced towards or by the end of the experiment. Fewer assumptions by the end of an experiment means that there is an increased understanding on the matter. 3. Briefly explain the goals or functions of science. The primary goals of science are description, understanding, prediction, and control. Description is where the phenomena is defined, while understanding is where the occurrence of the phenomena is determined. Prediction is done by forecasting or through hypotheses. Finally, the aim to control a phenomena follows after truly understanding it. The function of science, on the other hand, is to provide a factual reasoning regarding an idea. 4. What is meant by the term ââ¬Å"cumul ative nature of scienceâ⬠? Discoveries in science are interconnected and, to some extent, confirmation of its fundamental principles. This means that rejecting these fundamentals is synonymous to rejecting, and going through another process to understand, several previous successful researches and experiments. This is the cumulative nature of science. 5. Explain the importance of research having a theoretical base? It is impossible to do a research from all perspectives even on a single idea or matter. The theoretical base helps in establishing a standpoint, position, and a procedure on which the experiment will be based (Bryman, 2008, p.17). This means that creating a theoretical base is a step towards a clearer and narrowed research --- excluding other perspectives that might affect the research, while having the rationale for refusing to include these other perspectives. 6. Explain the basic ideas behind Wallace's Wheel. Wallace's Wheel is a good illustration of the concept of how the knowledge base of science develops and grows. It points out how scientific theories and scientific experiments and researches continuously form and mold each other. 7. List and briefly define the categories, or ââ¬Å"partsâ⬠of the research process. A typical research process has an introduction, a literature review, methodology, findings, and conclusion. The introduction should include information regarding the research such as primary objectives, benefits of the research, and even the researcher's background on the topic. The literature review is an overview of past researches related to the current one. The methodology is where the explanation of the procedure for the research is done. Findings discusses the analysis of the gathered date, and the conclusion is the summary of the whole project. The conclusion also discusses whether the primary objectives were met, and if further researches are suggested (Bryman, 2008, p.33). 8. Explain the difference between basic research and applied research. A basic research is a product of the researcher's interest or curiosity in a concept or idea. The main goal of this type of research is to expand the knowledge. On the other hand, applied research is a product of the need to answer the practical problems about almost anything. The main goal of this type of research is to improve human conditions (Bryman, 2008, p.26). 9. In a nutshell, explain human ecology theory.

Preferred Learning styles Essay Example | Topics and Well Written Essays - 1000 words
Preferred Learning styles - Essay Example This study was based on descriptive study. Quantitative data was collected from the closed ended questionnaires where the number of students were tallied and presented in a table form. The findings of the study showed that there is no perfect learning style as they have some fault. The study thus recommends that the learning institutes should recommend the best learning style based on the personal traits of the individual. CHAPTER ONE 1.1 Introduction This report focused on analyzing learning style in the learning process. The study focused on analyzing how the learning styles in a classroom set up is influenced by the gender or sex of the students. The study also focused on how the extroverts react to learning styles in a classroom set up. More so, this study focused on how social aspects of the students influence the learning styles. This report focused its premises on the Honey & Mumford learning style in its theoretical framework. In the independent variable, the study had the le arnerââ¬â¢s gender and characteristics. 1.2 Literature review This reports based its arguments on the recent literature reviews. The literature in this scope of study shows how learning style concepts have been accepted. It is alleged that several studies that have proved that learning styles area true measure of studentsââ¬â¢ self evaluation (Rosenberg, 2009) though there is a disagreement on the best way of measuring the various learning styles. It is also alleged that there are several researches that have been done on learning styles but most researchers have not agreed on the importance of designing learning programs (Hall, 2009). In addition, Coffield et al (2004) concludes that provision of correct learning strategies, contexts and methods is better as compared to matching individual student preferences. Marzano (1988) posits that tactile and graphic presentation of subject matter produced noticeable effects the outcomes of learning regardless of attempts to match the g raphic and tactile methods with learnersââ¬â¢ modalities. In a recent by Baker (2002), visual studies were quite advantageous among all adults despite the rate of learning style with preference to the visual images. It was also advantageous for learners with strong preferences in the verbal process. According to Merrill (2000), instructional strategies should be determined first by focusing on the goals of the instructions and the learnersââ¬â¢ learning preferences and styles are used to adjust the fundamental learning strategies. CHAPTER TWO 2.1 Research methodology The descriptive research design was used in this study. Hypotheses were set and later test made on the participants. The study was conducted in a workshop and follow up activities in the classroom set up. The study involved one classroom and all the students were participants in this study. Questionnaires were administered and the responses were analyzed in a table form. The test score for the various theories was analyzed in a table. The questions were aimed at critically analyzing the self evaluation of the respondents by determining the learnersââ¬â¢ style. There was no time limit to this questionnaire. The accuracy of the results depended on how honest you were. There was no right or wrong answers. If you agreed more than you disagreed with a statement, you had to put a tick next to it. If you disagreed more than you agreed a cross was put beside it. 2.2 Participants The research participants were students in a classroom set up.

Persuasive Speech-Problem & Solution Design Essay
Persuasive Speech-Problem & Solution Design - Essay Example Marriage is typically defined as the uniting of two people of the age of majority of their own free will and volition. In this way, regardless of culture contractual unions (often referred to as marriage) are recognized by the law of the state in every nation on the face of the planet. Child marriage is a situation where children are subjected to matrimony before they have achieved the legal marriage age. In the Middle East nearly half of Yemeni girls are married before they reach eighteen years of age. In some instances, marriages occur even before the tender age of 8. The law in Yemen set the minimum age at one that is approved for marriage to be 15 years; however, traditional customs more often than not continuously flout this law. 1. This is due in part to the fact that the law was continually interpreted differently by different individuals, the laws was changed in 1999 to allow marriage only after the point in time in which a girl reached the age of puberty. However, the issue with the change in the law meant that many tribal elders interpreted puberty to be as early as the age of 9. In the actual practice, it can be said that the law in Yemen allows women of any age to be able to wed, but it is forbidden to practice sex with them until they achieve the age where it is now considered suitable to do so. 2. The law was later to be raised from the minimum age of marriage to be 18 years after a girl, Nujood Ali, 10 years of age, in April 2008 was able to be granted divorce successfully after being raped under the set circumstances. Much later in 2008, a council for maternal care and childhood established a proposal for the minimum age to be defined at 18 years and was passed as law in April 2009. However, this law was to be dropped the very next day after maneuvers by parliamentarians opposed to it, and negotiations are still ongoing for the legislation to be

The Arab Spring Essay Example | Topics and Well Written Essays - 500 words
The Arab Spring - Essay Example The Arab Spring Freedom that if we do in other countries could either send us to jail or even killed. Yet we take it as an entitlement, something like a birthright. Not so long ago, there was a movement or uprising called The Arab Spring in the Middle East. We all saw it on TV, internet, newspapers and other forms of media but never really cared about. It was a movement of citizens to rise against their governments to have freedom and democracy so that their lives will become better. We may not realize it, but the freedom that our forefathers fought with blood, sweat and tears is not currently enjoyed by many people in other countries. Today, even as this paper is written, there are still a lot of people struggling and fighting for freedom. In the country of Syria, there is now a civil war going on where people have to fight, suffer and die by the thousands, sometimes brutally, just to have freedom. It started in the exercise of freedom that we take granted ââ¬â protesting and speaking against t he government. While this exercise of freedom is taken very casually here in the United states, that exercise of freedom in Syria was fired upon by the government forces where innocent civilians died. There are still a lot of countries where people do not have the freedom to speak against or criticize their governments. It may be a cliche to mention but its truism never fades no matter how many it is repeated ââ¬â that we will never know the true value of freedom until it is taken away from us.

Free trade and its effects on texas as a state and the US as a nation Essay
Free trade and its effects on texas as a state and the US as a nation - Essay Example While protectionist measures may sometimes have short term gains, in terms of the long view, free trade encourages competition and benefits the consumer. The state of Texas is a large state with a large international border, and several large metropolitan areas, several of which also serve as border cities with Mexico. Texas is also a state that has busy port cities. Therefore, ever since NAFTA, Texas has had an increasingly favorable free trade environment. ââ¬Å"Expanding trade has brought jobs and business to Texas but has left the state particularly vulnerable to antitrade actions. Texas would suffer greatly if the U.S. and other countries implement protectionist measuresâ⬠(Skelton, 2009). Texas sees various benefits from free trade, including exporting contracts which rival major east coast and west coast US states such as New York, California, and Florida. Therefore, many worry that protectionist measures will stifle Texasââ¬â¢ growth that it has seen since the mid 1990s in terms of free trade with Latin American nations and Mexico. However, as one source notes, ââ¬Å"This very success leaves the state exposed to pro tectionist experimentation, particularly in the Americas. While attempts to curtail imports and lock out foreign companies damage the U.S. economy and harm U.S. consumers, the effects would be particularly detrimental to the Texas economyâ⬠(Skelton, 2009). There are many perspectives to consider on the issue of free trade vs. protectionism. Questions of free trade and protectionism impact the US and international as well as the state levels, and there is an equal variety of points of view, some supporting free trade and some supporting protectionism. Kurlantzickââ¬â¢s article is critical of international expansion. The author posits that a more global atmosphere is facing many challenges in the present, despite a high point in the latter part of the twentieth century. ââ¬Å"Synchronized economic slowdowns in Asia, Europe and the United
