Building of Pyramids of Giza Essay Example | Topics and Well Written Essays - 250 words - 45

Building of Pyramids of Giza - Essay Example It is evidently clear from the discussion that modified external ramp theory explains that the Pyramid was created with the use of an external ramp. This ramp was believed to be raised during construction. It is believed that the ramp is corkscrewed or spiraled to the top of the Pyramid. That was the only way to explain how an external ramp was used since there was no way a single long ramp was built in the area.  Another theory, a more recent theory, was presented by Jeanne-Pierre Houdin (Brier, 2007; George, 2008). He was a French architect who believed that the Pyramid was built using an internal ramp. He explained that the bottom of the Pyramids was built using an external ramp and the higher parts were built using an internal ramp. He proposed this theory after seeing the spiral-like structure within the Pyramid. I believe that the more recent theory of the internal ramp can answer how the Pyramids were built. Although it is possible that humans can haul the heavy stones on to p of each other to build the pyramid, I find it hard to believe that it is only done outside of the Pyramid. There is evidence showing there is a structure within the Pyramid. And there are holes at turning points to help the worker haul the heavy stones up. I find Houdin’s theory more realistic because of the many pieces of evidence that point towards its possibility.

Network Security Assignment Example | Topics and Well Written Essays - 2000 words

Network Security - Assignment Example Information security entails the adoption of specific measures that are supposed to prevent the unauthorized access, manipulation, use or the denial of access to any data, information, or capabilities that will ensure confidentiality (Douligeris and Serpanos, 2007). All these measures should be implemented to ensure the security of all the resources within the organization. Organizations nowadays have greatly relied on the various network technologies that ensure efficient data communications between different departments, at the same time ensuring that communication channels are secure. The expansion of an organization results into more resources being acquired in terms of new computers, printers, telephones, communication channels, hardwares and software’s and also the adoption of sophisticated network architectures. This results into an increased concern for information security within the organization to ensure that only the authorized personnel access the resources. Quest ion 1. The question describes the main security issues, the principles of public key encryption, and the role of certification authority as follows: Security issues facing the expansion of the organization Expansion of the organization will result into a rise in the demand of various resources. More hardware and software will be acquired, more people will be employed, and the network architecture to be used and various protocols will change to meet the organizational needs. Various security issues will arise; in physical security, all the tangible assets within the organization such as computers (both personal and laptops), network printers, telephones, storage media, people, network cables, and servers will face a security threat. Indeed, each of the organizations assets faces a security threat from within (internal) and from outside the organization (external). Security issues that will arise from within the organization (internal attacks) include access attacks such as eavesdropp ing (listening to a conversation that one is not part of) by fellow employees or through wireless networks, and snooping (looking through information files). Others include interception of transit information, unauthorized access to computers by employees, computer attacks by viruses, worms, Trojans, internal hackers and theft of hardware from within the organization (Maiwald, 2003). External attacks include hackers and cyber terrorists, and malware. The organization needs to address the measures that will be used to ensure security of both information, physical hardware, internal and external attacks are checked. Internal threats from employees are both intentional and accidental, where an employee can eavesdrop on another employee, hence gaining access to some information during conversation. In addition, employees can forge passwords of their colleagues and hence gain access to their computers, use, modify, and transfer information to other unauthorized members outside the organi zation. Moreover, employees may bring external or foreign insecure hardware into the organization, resulting into virus infection and transmission. Lastly, employees could steal portable small size hardwares from the organization. Information and communication within the organization will be affected in one way or another. There might be lots of network traffic caused by attacks on

About a movie called (The Brother Grimm) Essay Example | Topics and Well Written Essays - 750 words

About a movie called (The Brother Grimm) - Essay Example The two move to a part of Germany occupied by the French in the 19th century and set up a phony witch. They use the fake witch to trick the residents of the Karlstadt of their mystical powers. The two brothers do their tricks so successfully that when a trouble befalls the city, the French General Delatombe summons them and tasks them with resolving the mystery. However, the mystery is an actual problem with real risks. A supernatural queen needs to drink the blood of young girls in order to regain her beauty. She, therefore, captures young girls from the village. The general tasks the two brothers with finding the queen, defeating her supernatural powers and rescuing the girls. The adventure thereafter is exhilarating as the two brothers fail twice and are on the brink of losing their lives. However, they eventually succeeded after a series of attempts. They rescue the village from the horrific queen. The film is an independent production directed by Terry Gilliam. Terry Gilliam is an American film director, actor and screenwriter. He contributed to writing and later directed the film. He has directed numerous other films some of which are adventure films. The Adventures of Baron Munchausen produced in 1988 was one of the adventure films he directed. However, The Brothers Grimm is unique as the director adopts a fiery tale approach in the development of the film. He produced the Brothers Grimm in 2005, a period when the film industry globally was burgeoning. The film, therefore, portrays the development of the film industry as Terry Gilliam revamps his creativity in authoring the script and directing the film. The developers of the film employ various elements of film development strategically thereby enhancing the effectiveness of the film. Key among such elements in the film is lighting. Lighting plays an integral role in illuminating the setting among other

The Scarlet Letter as a Love Story Essay Example | Topics and Well Written Essays - 1500 words

The Scarlet Letter as a Love Story - Essay Example In much the same way, Nathaniel Hawthorne’s penultimate novel, The Scarlet Letter, has continued to evoke a level of controversy among scholars and casual readers alike. The underlying root of this controversy is whether or not this particular novel can in fact be described as a love story between Hester Prynne and Arthur Dimmesdale; the two main characters around whom the novel focuses. Accordingly, in seeking to analyze this particular question and providing a level of textual support to serve as evidence with regards to the stance of this particular student, the following discussion will be concentric upon promoting the idea and understanding that even though many other themes exist within this particular novel, an unmistakable and easily denoted reality is that the action of the entire piece is predicated not upon lust, betrayal, adultery, or public censure; rather, it is predicated upon a disarmingly complex yet simple love story between the two main characters.... Ultimately, the author, Hawthorne, was somewhat disquieted about writing such a simple love story. In this way, the introductory quote that is referenced above helps to serve as something of a preliminary apology with regards to presenting such a complex love story within the guise of something seemingly different. Further on in the story, Pearl asks a telling question that turns into something of a prophetic comment which further helps to prove the underlying nature of the novel as a love story. Says Pearl, â€Å"Mother,† said little Pearl, â€Å"the sunshine does not love you. It runs away and hides itself, because it is afraid of something on your bosom. . . . It will not flee from me, for I wear nothing on my bosom yet!† (Hawthorne 99). The clear level of understanding that can be had with regards to this specific quote is the fact that even though it is not clear whether or not Hester waits for the father of Pearl to come back into her life, Pearl seems to understa nd perfectly well that this is the case; equating â€Å"the sunshine† with Dimmesdale; retreating, hesitant, uncertain, and fearful because of the stigma that the adulteress has upon her character. In this way, even though a clear determination at this point of the story does not reveal whether or not the entire tale should be considered a â€Å"love story†, Pearl’s prophetic level of understanding seems to leave no doubt with regards to the true nature of the novel. Similarly, another quote that helps to solidify the understanding that the novel of the Scarlet Letter is in fact a love story is with regards to the following quote. Says Hawthorne, But Hester Prynne, with a mind of native

The Effects of Poverty on Teaching and Learning Essay Example for Free

The Effects of Poverty on Teaching and Learning Essay Teachers need to understand how poverty can affect a student in the classroom. Some students who suffer from poverty may come from homes with very young, single or low educational level parents. Their parents may be unemployed, have substance abuse problems or generally may not be good role models. Students might live in dangerous neighbourhoods or suffer from homelessness. They might move areas often; their parents may have had bad experiences with schools themselves and see schools as threatening institutions and do not value education. Perhaps they come from households where the parents are family orientated and loving, their only problem being lack of money. Teachers need to understand the family background to understand how to best assist the student. Teachers must be aware of the problems and difficulties poorer students face and make allowances and adjustments to the curriculum to provide them with relevant learning without detracting from other students needs. Pellino (2007) writes of the lack of confidence many children of poor families have and how many see the curriculum as irrelevant to their lives. She suggests modifying the curriculum in interesting, simple ways that will have value to all students in the class. This may include doing work on the effect of poverty, getting involved in community projects such as soup kitchens or simply studying the question What is poverty? It is important that these activities be followed with both group discussion and individual reflection to help children think critically about their experiences (Chafel, 1997). A good education is often the only means of breaking the cycle of poverty for poor children therefore a teacher must provide a curriculum that is relevant and challenging to motivate students and increase their opportunity for higher education and greater opportunity in life. Many students from low socio-economic households feel they have no choice or control over their destiny. They may be depressed, have a fear of failure or low expectations of their academic ability. An important task for teachers is to help students develop conative attitudes (Pellino, 2007). These are a desire to improve their life and an understanding that it is indeed possible through the creation of goals, plans and perseverance. It may be beneficial  to develop conative attitude exercises designed to help students identify what is important to them personally. Incorporating personal reflection in the curriculum may be beneficial (Pellino, 2007). This could include encouragement to write journal entries imagining what they would do if time and money was no object (Waitley, 1996, cited by Huitt, 1999) and then reflecting back on a mission statement. Students from low income families often need help to develop self-efficacy and a desire to be proactive in their life (Baumeister, Bratslavsky, Muraven Tice, 1998; Emmons, 1986). These are traits that are often lacking in low achieving students, particularly those from poorer backgrounds (Huitt, 1999). It is important for teachers to develop lessons that result in success to show students that they are capable of altering outcomes and do not just accept what life throws at them (Pellino, 2007). I found Karen Pellinos paper to be extremely helpful. It is comprehensive and includes an extensive reference list that directs the reader to a vast array of articles for further study. Reference list Baumeister, R., Bratslavsky, E., Muraven, M., Tice, D. (1998). Ego depletion: Is the active self a limited resource? Journal of Personality and Social Psychology, 74(5), 1252-1265.

Psychology Essay examples -- science

Psychology Males and females have many different opinions in term of choosing their mates and long-term partners. But I strongly agree with Buss on the idea that women give more importance to kindness and generosity in term of choosing their long-term partner. Because I noticed that a man who is kind and generous will spend more time on her and then show love and take good care of the family. But one thing that I do not really agree with Buss is the idea of resource, I do believe that women give importance to resources but to me it is not just for their children but also most for themselves. Because I have the example of a two kids mom who divorce with her husband after he won three million dollar last summer. By divorcing, she did not care about the kids but the money. Also we have more and women who do not want to have kids and still choose their mates base on financial views. One more thing is that I noticed that women like to show off. For example they like to wear expensive clothes with brand name such as Kenneth Cole, they like diamonds and gold. Also women like to enjoy life especially by going to vacation in the Caribbean (Trinidad and Tobago). So women are more likely to refer on financial view in term of choosing their mates beca use they want to acquire that stuff. Men in the other hand do give too much importance to money because they think that they are the ones who have to provide for the family. The primary difference between Hetherington and Wallerstei...
