Integrating Major and Core - Essay Example As a network administrator, the concepts about ethics and self morality are essential because it allows me to explore myself as a person and not just as a network administrator. For example, it is clear that I must think like a human before putting my network administrator hat on. Additionally, one must understand the principles of networking ethics that come with it, which will really help me In 21st century, the recent era of concepts of community surrounding technology has been a dogmatic notion. We are constantly bombarded with security risks and threats. One of the main risks as a network administrator are security threats and how it can affect the community I reside in. For instance, the concept IT systems continue to evolve, security becomes a crucial element that must be carefully analyzed. Most organizations feared cloud computing because of its ability to be flexible within user domains. This poses a problem for organizations that did not have scalable solutions, but needed the concept of security embedded within their data. Corporations prefer private clouds because administrators control access through policies which designate capabilities. In addition, there are many opinions regarding technology scientists discussing the functionality of networks, specifically in regards of private clouds, who have a great capability to maintain a secured environment and be integrated with a public cloud. The main core classes will facilitate my growth in a similar fashion. As a matter of fact, these notions dominate the public community Moreover, the delegated administrators can manage a scoped environment. Without a doubt, it is still unclear how safe out-sourced data is and when using these services ownership of data is not always clear. Another concept is delegating network access that is not moral, such as watching adult videos over the

What are the advantages and disadvantages of the referendum as a Essay

What are the advantages and disadvantages of the referendum as a decision mechanism to solve the principal agent problem in political representation - Essay Example The two common types of referendum include; obligatory and facultative referendums. Obligatory referendum emerges when electorate’s votes have the right and responsibility to vote for a particular policy as may be defined by the constitution (Dovi, 2011). The outcomes of electorate’s votes in a referendum are legally binding. On the other hand, facultative referendum involves a vote by certain groups such as parliamentarians, electorates, executives and electorates. Normally, facultative referendum may be carried out in order to make amendments in some sections of the constitution. Facultative referendum may be carried out if certain provisions within a constitution require some amendment (Local Direct Democracy in Europe, 2011). Whereby, citizens might be required to give their opinion by participating in a referendum. In above connection, the outcome of a referendum represents the voice of majority because all citizens participate collectively in a decision making pro cess (Republic of Moldova, 1999). However, the outcomes of a referendum may not always represent a true voice of the electorates because of some political influence before and during the referendum. Whereby, some politicians ay influence electorate’s decisions by manipulating them to accept or reject a particular legislation for their own personal gains (Tierney, 2012). Normally, politicians act as agents while the electorates/ citizens act like the principal. Therefore, the agents have the obligation to act at the best interest of their principle in order to ensure that there is proper agency relationship. This means that conflict of interest may occur when politicians tend to pursue their own personal interest at the expense of their citizens. For instance, politicians may pass those bills that suit their needs at the expense of the electorates (Schiller, 2011). In above connection, referendum may be involved

Nanotechnology in Aeviation Essay †¢Nanotechnology in Aerospace Materials †¢Introduction Figure 1. The aerospace industry is under pressure to improve its environmental footprint, primarily by making aircraft more efficient. Image credit: Bureau of Labor Statistics. †¢There are few industries where the applications of nanotechnology are so clearly beneficial as in the aerospace industry. The primary development goals match almost exactly with the advantages offered by using various nanomaterials in the place of traditional bulk metals like steel. †¢The aerospace industry is one of the most important heavy industries in the world. Countless companies rely on the ability to ship products and people around the world with the speed that can only by achieved by air. The aircraft manufacturing market was worth xxx billion in 20xx, and the bulk of this was accounted for by military spending. †¢Along with this huge economic value, however, comes huge consumption, and one of the largest carbon footprints on the planet relative to the size of the market. For this reason, the major drivers in current aerospace RD are towards lighter construction materials and more efficient engines the overall goal being to reduce fuel consumption and carbon emissions associated with air travel and air freight. The significant interest in nanotechnology for the aerospace industry is justified by the potential of nanomaterials and nanoengineering to help the industry achieve this goal. †¢This article will review some of the nanomaterials which are already being applied in aerospace manufacturing, and the benefits they can provide. †¢Nanostructured Metals †¢Bulk metals with some nanoscale structure are already widely used in aircraft manufacturing. It is now well known that nanostructured metals exhibit considerably improved properties compared to their counterparts with microscale or larger grain structure. †¢This is particularly noticeable for properties which are crucial for materials used in aircraft primarily yield strength, tensile strength and corrosion resistance, coupled with low density which helps keep the total weight of the aircraft down. †¢ †¢Figure 2. Bulk nanostructured metals exhibit much better mechanical properties and corrosion resistance than their counterparts with larger crystal structures. Image credit: Los Alamos National Laboratory. †¢Polymer Nanocomposites †¢Various nanomaterials have been used as filler materials to enhance the properties of structural and non-structural polymers used in aircraft construction. The most commonly used nanomaterials include nanoclays, carbon nanotubes, nanofibres, and graphene. †¢Carbon nanotubes in particular have been shown to give excellent advantages when used as fillers in various polymers, due to their exceptional stiffness, toughness, and unique electrical properties. †¢Nanocomposites typically have superb weight-to-strength ratios, and enhanced resilience to vibration and fire, making them ideal for use in the aviation industry. The properties of the nanofillers, like the conductivity of nanotubes, for example, can create interesting opportunities for multifunctional materials. †¢The properties of polymers enhanced by nanomaterial fillers are so well-tuned to the requirements of aircraft manufacturers, that they are actually being used to replace some of the metals used in the airframes. This obviously brings along huge weight savings, and often cost savings as well. †¢Tribological and Anti-Corrosion Coatings †¢Another major trend in the materials used in aircraft is towards nanocoatings to enhance the durability of metals. In particular, magnesium alloys, which are far lighter than steel or aluminium, are prone to corrosion, due to the high chemical reactivity of magnesium. Coatings can help prevent corrosion, but the type typically used contain chromium complexes which are a highly toxic pollutant. †¢Materials used for these novel anti-corrosion nanocoatings include silicon and boron oxides, and cobalt-phosphorous nanocrystals. †¢Nanocoatings are also now being used on turbine blades and other mechanical components which have to withstand high temperatures and friction wear. Tribological coatings can drastically lower the friction coefficient and improve resistance to wear this greatly improves the efficiency of the engines. †¢Many nanostructured and nanoscale  coating materials have been suggested as possible friction modifying agents, such as carbides, nitrides, metals, and various ceramics. †¢ †¢Figure 3. The defense sector drives a lot of the innovation in many industries, and aerospace is no exception. High-performance military aircraft require exceptional materials, which will eventually find their way into commercial vehicles. Image credit: Penn State University. †¢Conclusion †¢This is just a brief overview of some of the nanomaterials being used in aerospace. The drive for lighter and more efficient air vehicles has led to the rapid adoption of nanotechnology in aerospace manufacturing. †¢The main roadblock, as with many industries looking to adopt nanotechnology, is caused by uncertainty over the environmental and health and safety implications of these materials. Whilst nanomaterials can often be less toxic than the current materials used, the effects of long-term exposure to these novel materials are still uncertain. †¢The potential of nanotechnology in the aerospace industry cannot be denied, however. Outside of airframe and component materials, nanotechnology applications have been found in lubricants, fuel, adhesives and many other areas. †¢Nanotechnology is also helping engineers to create vehicles with the necessary properties to endure the harsh conditions of space.

The Importance of the Sea in Chopin’s The Awakening Essay examples --

The Importance of the Sea in Chopin’s The Awakening Unlike Marà ­a Eugenia, Edna in Kate Chopin’s The Awakening chooses not to fill her family’s expectations. As she takes her final steps into the sea she thinks to herself: â€Å"they need not have thought that they could possess her, body and soul† (655). Edna treasures her autonomy and chooses death over familial subjugation. However her transformational journey, alluded to by the title of the novel leads to more than the rejection of her self-sacrificing familial roles as wife and mother and her death. We first meet Edna on her way back from a swim with Robert Lebrun, as Chopin begins to establish Edna’s burgeoning transformation in the context of her relationship with Robert and to the sea. While Robert and Edna’s relationship develops, Edna becomes increasingly dissatisfied with her marriage to Là ©once Pontellier and her traditional roles as wife and mother to her two children, Rauol and Etienne. Edna learns to swim, takes up painting, befriends Madame Reisz, an eccentric old woman that plays the piano, and moves into her own house. After Robert leaves for Mexico, she engages in an affair with Alceà © Arobin, until Robert returns and they affirm their love for one another. However, Robert, afraid of the social repercussions of their affair, leaves town. As a result of losing Robert, failing to find fulfillment in her life without a man, and failing to reconcile her roles as a good and faithful wife and mother while becoming an artist and falling in love, Edna com mits suicide by drowning herself in the sea. The sea, or green-world token is present throughout the novel as Edna engages in her innermost thoughts and her relationship with Robert, the green-world lover. Although ... ...pport of Mr. Pontellier, her children, Madame Ratignolle, Robert, Madame Reisz, and her father. While Edna sees support for herself in these roles the way the other characters see them, she does not believe that she has their support for herself as an individual, apart from these roles, or as a person defining these roles for herself. As she takes her final walk down to the beach, the sea continues to call to her soul: â€Å"The voice of the sea is seductive, never ceasing, whispering, clamoring, murmuring, inviting the soul to wander in abysses of solitude† (654). The sea has helped Edna see into her innermost being and the transformational journey has helped her realize that she wants to fulfill her roles in life as an autonomous individual. But because Edna feels that she cannot achieve her goals, she succumbs to that which is closest to her innermost being, the sea.

Pit-Bull Case

Legislation over the long-standing debate regarding the safety of housing Pit Bulls continues between pro Pit-Bull advocates and those fearing for their safety throughout Canada. Today, the issue of housing large, potentially dangerous dogs in the city has reached pivotal concern. A course of action is necessary. The level of concern surrounding Pit Bulls is greater than the concern over other dangerous domesticated dogs. There are, however, people who enjoy having Pit Bulls as pets. Pit Bull owners constitute a smaller percentage of people in comparison to those with concern over a Pit Bull’s safety. It comes down to pure fear over these life-threatening dogs. Yes, the anti-Pit Bull contingency has a voice, and with justifiable concern. Evaluation is in order regarding the pros and cons surrounding this issue. This position paper will clearly show that all breeds of Pit Bulls should not be housed in cities throughout Canada. There are many breeds of Pit Bulls—all of which can be threatening. The various breeds of other dangerous domesticated dogs are even larger. Lawyer Clayton Ruby argues the legislation. He sites the following: since 1983 there were 23 dog attacks in Canada that led to fatality. Of these 23 attacks, only one involved a Pit Bull. Thus, according to Mr. Ruby, legislation needs to be written governing all dangerous dogs, and not just Pit Bulls. The slant here, however, will be focused on developing legislation that will make it illegal to own a Pit Bull if you reside in a major city in Canada’s surrounding Provinces. First, we must consider the levels of all dog aggression in comparison to Pit Bulls’ aggression. The least dangerous level is called the submissive level. It includes dogs that display very little signs of aggression. Dogs of this nature tend to roll over when challenged and they will not respond with aggression. No Pit-Bull, regardless of breed, meets these criteria. The next level of dog aggression is known as the generic level. This level of dog aggression only demonstrates hostility if another angered dog approaches it. At this level, if attacked, a generic dog will respond with just enough tenacity to repel the instigating dog from its assault. Again, there isn’t a single Pit Bull that is calm enough to match this non-threatening level. The next level of aggression meets the characteristics of a Pit Bull Terrier. This Pit Bull, labeled a happy-normal-Pit-Bull-Terrier, is a dog that only displays aggression when challenged. This dog will respond aggressively. The only way to separate an aggressive Pit Bull Terrier is by using a ‘break-stick’ level of restraint. These restraining traits must be learned from trained specialists. Here in lies our first red flag. If even the most receptive breed of Pit Bull has a tendency for hostility, it is not feasible to consider Pit Bulls as an environmentally-safe pet, especially in the confines of a city. Pit Bulls at their most obedient level will always attempt to make friends with new dogs. This unreserved level of sociability in a Pit Bull can be the catalyst that leads to aggressiveness and fighting, or even death. When we add a Pit Bull that lives in a crowded city, the situation becomes grave and the opportunity for an unfortunate incident increases. It’s important to point out that even the friendliest Pit Bull will not tolerate aggressive behavior. If, for example, a Pit Bull is led through a small city park where people take dogs and children to play, there is a greater chance for altercation. Even if leash-restrained Pit Bulls are led through a city, the opportunity for an unfortunate encounter, on any given sidewalk might occur. Dogs, by nature, tend to gravitate toward one another. This curious sniffing can lead to danger if a Pit Bull is involved. The next level of Pit Bill is known as the average Pit Bull. These dogs will exhibit aggression toward strange dogs of the same sex while acting cautious around dogs of the opposite sex. If an average Pit Bull is challenged, they will counter with aggression. Physical intervention is necessary to separate a fight. Lastly, we come to the dog-aggressive-Pit-Bull. Pits at this level can live with other dogs but will attack any strange dogs (strange refers to any dog unfamiliar to a Pit Bull). Again, the only means of alleviating aggressive encounters between dogs at this level of aggression is by physical intervention. The fights can be very serious. There are a large number of variables that can occur to a Pit Bull in a city that would lead to aggression. Sometimes it only takes curiosity from neighboring dogs or young children to initiate a Pit Bull’s innate sense for violent tendencies. Legislation that does not allow city-dwellers to own a Pit Bull needs to pass. So many people live together in tight quarters in Canadian cities. This makes it an unsafe region for Pit Bulls. This legislation must come to action before another person or animal is maimed or killed by these instinctively dangerous dogs.

10 Geographic Facts About Sichuan Province, China

Sichuan is the second largest of Chinas 23 provinces based on its land area of 187,260 square miles (485,000 sq km). It is located in southwestern China adjacent to the countrys largest province, Qinghai. Sichuans capital city is Chengdu and as of 2007, the province had a population of 87,250,000 people. Sichuan is an important province to China because of its abundant agricultural resources which include such Chinese staples as rice and wheat. Sichuan is also rich in mineral resources and is one of Chinas main industrial centers. The following is a list of ten things to know about Sichuan Province: 1) Human settlement of Sichuan Province is believed to date back to the 15th century B.C.E. In the 9th century B.C.E., Shu (what is present-day Chengdu) and Ba (todays Chongqing City) grew to become the largest kingdoms in the region. 2) Shu and Ba were subsequently destroyed by the Qin Dynasty and by the 3rd century B.C.E., the area was developed with sophisticated irrigation systems and dams which ended seasonal flooding of the region. As a result, Sichuan became the agricultural center of China at the time. 3) Because of Sichuans location as a basin surrounded by mountains and the presence of the Yangtze River, the area also became an important military center throughout much of Chinas history. In addition, several different dynasties ruled the area; among them are the Jin Dynasty, the Tang Dynasty, and the Ming Dynasty. 4) An important note about Sichuan Province is that its borders have remained mostly unchanged for the last 500 years. The largest changes occurred in 1955 when Xikang became a part of Sichuan and in 1997 when the city of Chongqing broke away to form a part of the Chongqing Municipality. 5) Today Sichuan is divided into eighteen prefecture-level cities and three independent prefectures. A prefecture-level city is one that is below a province but ranks higher than a county for administrative structure. An independent prefecture is an area that has a majority of ethnic minorities or is historically important for ethnic minorities. 6) Sichuan Province is within the Sichuan basin and is surrounded by the Himalayas to the west, the Qinling Range to the east and the mountainous parts of Yunnan Province to the south. The area is also active geologically and the Longmen Shan Fault runs through part of the province. 7) In May 2008, a magnitude 7.9 earthquake occurred in Sichuan Province. Its epicenter was in the Ngawa Tibetan and Qiang Autonomous Prefecture. The earthquake killed over 70,000 people and numerous schools, hospitals and factories collapsed. Following the earthquake in June 2008, severe flooding from a lake formed by a landslide during the earthquake occurred in low-lying areas that had already been significantly damaged. In April 2010, the region was again impacted by a magnitude 6.9 earthquake that struck neighboring Qinghai Province. 8) Sichuan Province has a varied climate with a subtropical monsoon in its eastern portions and Chengdu. This region experiences warm to hot summers and short, cool winters. It is also typically very cloudy in the winters. The western part of Sichuan Province has a climate affected by the mountains and high altitude. It is very cold in the winter and mild in the summer. The southern part of the province is subtropical. 9) Most of Sichuan Provinces population is Han Chinese. However, there is a significant population of minorities such as Tibetans, Yi, Qiang, and Naxi in the province as well. Sichuan was Chinas most populous province until 1997 when Chongqing was separated from it. 10) Sichuan Province is famous for its biodiversity and the area is home to the famous Giant Panda Sanctuaries which consist of seven different nature reserves and nine scenic parks. These sanctuaries are UNESCO World Heritage Sites and are home to more than 30% of the worlds endangered giant pandas. The sites are also home to other endangered species such as the red panda, the snow leopard, and the clouded leopard. ReferencesNew York Times. (2009, May 6).

American Dream in a Raisin in the Sun - 4319 Words

CHAPTER III: The Impact of Identity on Dreams – 1. Identity in the Sight of Other People In actual fact, people have a certain view or conception about what somebody is. This view is quite different from what the individual himself has. But then the harm in all this is that this state of affairs has a great impact on what an individual is supposed to become in life especially when he doesn’t have a great sense of objectivity or when he is not determined to achieve his life goal regardless of the opposition or the influence exerted upon them by society. . . Often times, this conception of somebody makes him loose his self-confidence and try to comply with what others want him to be or think he is. In trying to reajust his nature in†¦show more content†¦His closing rhetorical question – â€Å"Or does [a dream deferred] explode?† – is incendiary, a bold statement that the suppression of black dreams might result in an eruption. It implicitly places the blame for this possible eruption on the oppressive society that forces the dream to b e deferred. Hansberry’s reference to Hughes’ poem in her play’s title highlights the importance of dreams in A RAISIN IN THE SUN and the struggle that her characters faced to realize their individual dreams, a struggle inextricably tied to the more fundamental black dream of equality in America. These dreams functioned in positive ways, by lifting their minds from their hard work and tough lifestyle, and in negative ways, by creating in them even more dissatisfaction with their present situation. For the most part, however, the negative dreams come from placing emphasis on materialistic goals rather than on familial pride and happiness. Therefore, while the Youngers shared a common dream of having a better life, each family member had their own dream in obtaining it. Unfortunately, their dreams had been deferred for so long that their frustration almost succeeds in destroying the ultimate dream. This frustration is best summed up when Beneatha, who has lost fait h in her brother, says, Well, we are dead now. All the talk about dreams and sunlight that goes on in this house.
