Network Technology and Network Administration Essay

Network Technology and Network Administration - Essay Example It can be proved by unusual requests and complaints network pros have gotten from end users. So, now basic need is to generate awareness among all users so as to lessen the load on IT professionals. 3. Todd Fink, senior telecommunications administrator at Premier Bankcard in Sioux Falls, S.D., once got a request from a user looking for another coffee holder for his computer. After asking he came to know that customer understood CD ROM drive as coffee holder. Looking at above complaints and stories it can be understood that how important basic knowledge of computer and internet is for every user. Users don't need an encyclopedic knowledge of how their computers work or how network is configured--but they may need a little technical enlightenment here and there. Organization may provide new users with any substantial training or indoctrination to help them understand IT policies and best computing practices, and that often translates into problems for support techs. One way to head off at least some of the problems is to educate users about certain key computing basics. This will save time and money of users and organization as well. Here are some important things that are most critical for users to know, such as how to: Computer software is a compilation of structured, written instructions that are executed by the physical components of personal system. Physical components of your PC do not understand human language, so those instructions are written by highly trained computer programmers, using languages (set of commands) that your personal computer does understand. Examples of software are windows, Linux etc Physical Parts of PC (Hardware) You use computer programs Computer programs take your commands through Keyboard or a Mouse Computer programs use the special language to communicate with CPU CPU executes what

Beyond the All Blacks Representations - Essay Example The article by Uperesa, Fa‘anofo Lisaclaire (Lisa) addresses a number of issues with relation to how that Samoan has received support in American field football. In American SÄ moa (and other transpacific Samoan groups), football has come to speak to both a genuine and envisioned approach of getting out of what appears to numerous as a choked field of plausibility. The permeability and liveliness of football in American SÄ moa are established in Samoan histories of relocation to the United States, Samoan social sensibilities, the changing business sector of the American football industry, and narrowing financial opportunities (Uperesa, 2014). The transnational way of football relocation is vital to understanding the offer of playing football, the prizes that collect to effective players and how these assets have kept on changing states of probability. These changes have been in relation to the ideology and materialistic approach that the youngsters in the islands consider A merican Football to bring about. Through the author, this article investigates the layered and complex inspirations for football interest as molded by forthcoming types of capital, authentic possibility, and transnational brandishing organizations. Concentrated on history, economy, and a changed vision without bounds, it offers a basic ancestry of football in (American) SÄ moa and Samoans in football is an instrumental breakthrough in shaping the societies that participate in such competitions (Uperesa, 2014).

Urban Consolidation and Environmental Sustainability Essay Example for Free

Urban Consolidation and Environmental Sustainability Essay Urban consolidation is a rising issue in amny capital cities and could have a dramatic effect on the environmental sustainability of Australian cities in the near and distant future. â€Å"Urban consolidation policies concentrate on increasing housing densities in the large cities to produce more compact development, shorter travel distances and less dependence on automobiles. † (Forster 2004, p. 171). Some of the main negative issues that is caused by urban consolidation are a drop in value of pre-existing suburban housing, an overload of public resources in over-crowded cities and traffic and transport inconviences. There are many benefits to urban consolidation which involve lower short term envirnomental impacts and high levels of convience, but at the same time there are many disadvantages which are discussed in this essay. The policies of urban consolidation are surrounded by the idea of building large cities upwards, rather than outwards. This means that they are focussing on constructing multi-story facilities close to the centre of the cities. â€Å"more compact development would reduce the rate at which urban expansions consumes good agricultral land and threatens sensitive natural environments† (Forster 2004, p. 71). Existing housing urban housing and facilities must be demolished to make way for new high rise structures. This indicates that for many australians who have worked hard to buy/own their own home in the inner suberbs of major cities, it will be a struggle for them, due to the fact that their house/dwelling or property will decrease in value. As the population increases, the total of vehicles increases aswell. â€Å"In 1945 there were 100 cars per 1000 people, by 1970 there were almost 500 cars per 1000 people†(Forster 2004, p. 17), this will cause traffic congestion within the cities. As a result of traffic congestion, pollution levels will increase. This will negatively affect peoples health and well being. Along with the inconviences of urban consolidation on the everyday lifestyle, health issues can also be inflated. Childhood obesity is more likely to occur in children that were raised in areas of urban consolidation rather than a child raised in a suburban area, â€Å"urban sprawl communities separate people’s homes from stores, offices, services and restaurants. This makes it nearly impossible for people to carry out their errands, sporting activities or go to work without using their car†(Lopez 2004). This is largly due to the fact that children raised in urban consolidation generally have little access to large parks and playgrounds and would have to go out of their way to be highly active on a regular basis, where as children in suburban areas have access to these large parks and outdoor play areas. There can be many negatives with living in an urban consolidated area which can be an overcrowding in kindergarden and schools, lengthy waiting lists to seek medical attention and a possible need to travel further distances to get to bigger and better-equipped shopping districts. These needs negate the value of urban consolidation in that if many people will still be required to travel moderate or lengthy distances to access facilities then they would be better off to live further into the suberbs where the shops/facilities are well equipped. In conclusion, the policies of urban consolidation would be highly beneficial and have great outcomes in all major Australian cities if the preceding measures were taken care of prior or at the same time to taking action against urban sprawl. Although there are some positives to urban consolidation, such as lower automobile dependance and increased convinience, the many negatives outweigh them. In the long term the policies of urban consolidation may benefit some major cities in australia, but given the current situation in which many cities are not developing at the same rate as urban consolidation is affecting them, it stands that urban consolidation is not the answer to environmental sustainability for Australian cities.

Superstructure Construction Material Suitability

Superstructure Construction Material Suitability EXECUTIVE SUMMARY This project involves the selection criteria of the material used to construct a three story college building superstructure at the brown field site. Generally superstructure is the above foundation/ground level part of the building. The main goal of this report is to analyze several materials and the suitability for superstructure construction. We will analyze the following materials; reinforced concrete, steel, timber and then select one most suitable material for our project. The main goal of the report is to analyze three of the possible materials suitable for the superstructure and select the most suitable materials for different elements while considering the sites generic and specific implications. Components of a superstructure Before we analyze and give a recommendation of the best suitable materials for a superstructure it is important to understand the various components that make up a superstructure. This includes; columns, slabs, walls, roofs and beams. In details Columns Columns are the perpendicular load bearing elements of the superstructure and can be either for architectural or engineering purposes. Architectural columns are majorly for aesthetics while engineering columns are for support/load bearing and are used to transmit loading to the footing then to the ground. In some cases structural columns are decorated to improve its aesthetics. Columns can be made in either reinforced concrete, steel or timber based on several suitability factors like the size of the structure, materials availability etc.   For this case we will use steel frames encased in concrete cover for columns. Column construction will involve; Colum formwork, Colum reinforcement, concrete pumping and formwork lifting. Slabs These are the flat and horizontal components of the building where the weight due to different elements like occupancy act on. Slabs can be made of either reinforced concrete, steel or timber. For this case we will use concrete slabs. . Slab works consists of the following steps: Slab formwork, concrete pumping and finally the formwork lifting Beams Beams are the horizontal elements used to transfer the structures weight to the columns which then transmit the weight to the footing then to the ground. They can either be made of reinforced concrete, steel or wood. For this project steel beams will be used. The construction of the steel beams which will then be encased in concrete. Beam construction will involve Beam reinforcement, beam formwork, concrete pumping and lifting of the formwork. Walls Walls are the building enclosing structures and can either be load bearing or non-load bearing part of the superstructure. Walls can either be made of reinforced concrete for load bearing walls and either timber, masonry bricks, straw, etc. for non-load bearing walls. Roofs Roofs are the overall top part of the structure mostly used a shade and protection of the building from excessive rain and sun, The roof structure design is influenced by many factors like, the span of the building, the types of roof cover to be used, roof cover and weather load, cost, aesthetics MATERIALS REVIEW It takes a combination of many different materials to complete a building construction project Reinforced concrete Reinforced concrete a mix of concrete and steel reinforcements. Concrete is one of the most ancient construction materials and it was employed by romans as early 100 BC and has extreme compressive strength. To achieve much higher tensional strength while constructing, concrete is mixed with steel bars to form reinforced concrete that has an overall greater strength than either steel or concrete alone, Benham, 1983. Reinforced concrete is widely used in the construction of various elements of a superstructure of buildings; columns, beams, slabs and shear walls. Concrete is normally poured around steel formwork and the shape is determined by the encasements used to limit the movement of concrete. The concrete is then left to dry to achieve the various structural elements and maximum strength. (Abdulla 708477) Steel. There are several metals used in construction but steel is the most popular of them all and it has been used over centuries now. Steel has got numerous applications that range from decorative to structural support to reinforcements. Steel applied independently and not in concrete is known as structural steel. Structural steel is mostly used to refer to hot rolled steel sections, plates and shapes. The different structural steel shapes are as a result of passing heated steel strips through successive rollers with respective molds. (Ali 708389) Wood Wood is among the earliest materials ever used in construction and is still being widely used despite the popularity of concrete and steel. Wood is mostly used for structural framing (finish carpentry), cabinetry, trim, floors. Wood has high strength in compression, tension and bending in relation to its weight. Wood also has extremely good impact resistance. In current times there is an increased use of timber as plywood (Glue laminated timber) to achieve even much great strength and lengths. In this glue laminated timber wooden frames are arranged at right angles to each other. This maximized the strength of the wood. (Mohammed 729291) MATERIAL SELECTION (REINFORCED CONCRETE FOR THE SLAB WHILE STEEL FRAMES FOR SLABS AND COLUIMNS) Our material of choice for this case is reinforced concrete and steel. Concrete is the most used construction material world-wide and its application is very ancient with very few changes introduced along the years. Due to this few variabilities in development, concrete execution technique in constructions are well established so as to achieve perfect structures. Steel follows closely with it being popular with multi story structures. Concrete is an artificial mixture made from Portland cement, aggregates and water. Cement has been in use around the world for numerous years but the most commonly used cement today (Portland cement) was invented in Britain in the year 1824. Portland cement is produced by mixing ground limestone, shale or clay, sand and iron ore then the mix is heat to 1600 degrees Celsius in the rotary kiln. Concrete is formed by mixing the Portland cement and aggregates and water whereby a chemical process called hydration occurs. The hydration process forms concrete which is in plastic state and it transforms into solid state in about 2 hours. The concrete continually gains strength on cooling with maximum strength at the 28th day given the curing is done correctly, SUITABILITY OF CONCRETE FOR THE CONCRETE SLABS The following properties of concrete makes them the best suited materials for construction of slabs. Concrete is a mix of several materials formed through solidification of cement, water and aggregates (either fine or course aggregates or both). Reinforced concrete is steel rod enhanced concrete to achieve a much higher strength. High Compressive and Tensional strength The strength of concrete is generally higher than most of the other construction materials. The strength of concrete is determined by the water cement ratio and the lower the ratio the higher the final strength of the given concrete. There are two components used in classifying the strength of concrete as a suitable construction material, Neville, 2011 Compressive strength of concrete This the maximum resistance ability of concrete to axial loading at an age of 28 days after mixing, placement and curing. Compressive strength of concrete is measured in Pounds per square inch (psi). During the first 28 days, concrete achieves about 90 % of its strength and it is important to ensure sufficient curing disallowing drying/freezing so as to achieve this strength. The concretes compressive strength is dependent on quality and proportions of the concretes ingredients and the curing environment. Neville 2011, Tensional strength Reinforced concrete derives its tensional strength from using steel reinforcement bars. Steel has extremely good tensional strength with relatively low compressive strength as compared to concrete. The combination of the two harness the compression and tensional strength of each other to achieve higher overall strength. Mtallib, 2010. Workability It is much easier to work with concrete in construction of the super structure. This is due to its plastic state within the 0 2 hour range. Workability can be termed as the ease with which it can be mixed, placed, compacted and finished. There are however several factors that influence the workability of concrete which include; Characteristics and quantity of the cementing materials, the slump (concrete consistence), duration and the method of transportation, the percentage of the entrained air, the aggregate grading, surface texture and shape, water content, ambient and concrete air temperature, presence of admixtures The workability of concrete can be determined using a test called slump test that is basically the indication of the water content of a mix. The water content to a great extent determine the workability of any given concrete. Good adhesion to reinforcements One of the major factors that make concrete the most preferred materials in construction over ages is its great adhesion ability with different materials and more so with steel reinforcements. The bond strength between concrete and steel reinforcement bars are as a result of mechanical interactions, chemical reactions and thermodynamics reaction that happen upon placement of concrete to steel formwork. Kendall, 1983 Corrosion resistance The corrosion resistance ability of concrete makes reinforced concrete materials best suited against corrosion as compared to other construction material like wood and timber. Corrosion mostly affect the steel reinforcement and least concrete. Steel reinforcements are normally encased within concrete covering to reduce corrosive action of the environment and other materials to the steel reinforcements, Neville, 2011. Fire and Heat resistance Concrete has very high heat resistance compared to steel and wooden construction material. Reinforced concrete materials failure due to heat is mostly due to the failure of steel bars under extreme heat. However to counter this the concrete cover provides a good insulation of the covered reinforcement steel bars in extreme fire conditions. This provides more time for fire extinguishing and rescue in case of a fire hazard. Corrosion Resistance The corrosion resistance of concrete is very high hence can survive numerous types of environment. On the contrary reinforcement steel react to numerous aspects of our environments including humidity causing rust. Reinforced concrete is designed such that the more resistant concrete protects the much delicate steel bars. Sufficient density The density of reinforced concrete is basically the measure of its unit weight which is average weight density of 150 lb/ft3 (pcf).. This density is sufficient enough to protect the building from nature forces and other natural or induced forces that can affect the given structure SUITABILITY OF STEEL FRAMES FOR BEAMS AND COLUMNS Steel was selected for construction of the beam and column structural members due to the following reasons. Steel is easy to assemble It is much easier to assemble steel as the different steel frames can easily be fabricated to the required shape and size in the factory and then be carried to the given site for assembly. It is also easier and faster to fabricate steel at site as compared to concrete and wood making it cheap to build the given substructure. All this speed up the construction process while maintaining the required tight construction tolerance Steel is strong in both compression and tension hence high tensional and compressive strength. Steel has relatively very high compressive and tensional strength making it very suitable for construction of beams and columns. More and more stronger structural steel has been developed along the way and the yield strength of most structural steel in use today is more than 50,000 psi. Steel is more reliable and predictable Most steel is fabricated in the factories where its properties are closely monitored and controlled conditions by using very modern and recent technology in quality assurance Use of steel is more efficient. Construction of buildings using steel can be optimized by use of slender columns maximizing the floor space available for other things. Typical steel column occupies 75 % less space as compared to a concrete column References ACI committee, roller compacted mass concrete, part 1, ACI manual of concrete practice Benham, P.P, Warnock, F.V, 1983, Mechanics of solids and structures, Pitman publishing Limited, London UK British Standards, BS4449, British standards for reinforcing steel EN 10025; European structural steel code of practice.

The Development of Childhood Throughout History Essay -- Sociology

Throughout the history of childhood development poor social and economic conditions contributed to the many hardships and poor treatment of children. During the early Middle Ages the "paternalist" family concept evolved and the father had authority and control over family matters including the welfare and safety of his wife and children. Discipline was severe, young children both poor and wealthy were subjected to strict rules and regulations and often beaten if disobedient. Children took on the responsibilities of adults at an early age, sharing in the work of siblings and parents. Girls from affluent families were educated at home and married in their teens. Some males were educated at a monastery and others became apprentices to experienced knights. Children who were considered retarded or suffering from disease were abandoned to churches or orphanages. Relationships between parent and child were distant, and younger male and female siblings were considered "economic and social l iabilities." (Siegel 10). Custom and practices such as primogeniture and dower subjected many children to endure suffering and cruel treatment. These customs and practices often caused family rivalry, sometimes led to tragedy and had a significant impact on the role of women and children. Under primogeniture the oldest surviving male inherited family lands and titles. Younger siblings who were not fortunate to receive lands were forced to enter religious orders, become soldiers or seek wealthy patrons. Under the Dower system, a woman's family gave money, land or other wealth in exchange for a potential husband. This system "forced women into the role of second class citizens dependent on their fathers and brothers." Wet nurses took care of newb... ...rs (mandatory sentences) and target hardening techniques (steering locks, unbreakable glass on storefronts). This approach is not consistent with the viewpoint guiding the juvenile court because this type of deterrence punishment interferes with "parens patriae" philosophy. Juveniles are treated more leniently than adults, which limit the power of the law to deter juvenile crime. (Siegel 96). REFERENCES Siegel, Larry J., Brandon C. Welsh and Joseph J. Senna. 2003.

Schindler’s List, directed by Steven Spielberg and The Pianist, Directe

Schindler’s List, directed by Steven Spielberg and The Pianist, Directed by Roman Polanski The holocaust is seen as a time of horror, filled with brutal, inhuman actions carried out by the Nazi party. Schindler’s List, directed by Steven Spielberg, is one of the most realistic movies to show the gruesome shock of the concentration camps and torture of Jews. Spielberg captured the true essences of what pain was during World War Two. In 2002, Roman Polanski came out with The Pianist, a movie that focuses on a Jewish man’s struggles outside the walls of a concentration camp. Polanski created a movie that would leave an impression on the viewer. The main purpose of Schindler’s List and The Pianist is to provide an inside view of the torture and suffering the Jews faced during WWII and the movies use similar techniques to express the horrors. The movie Schindler's List, directed by Steven Spielberg, is a dramatic representation of the holocaust. First, the film starts in Poland, where the Jews are under pressure from the Nazi community making its way into the villages. Oskar Schindler is a Nazi business man seeking to build a factory with Jewish workers. Schindler contacts the correct officials to get permission to build his factory. Next, the Jews are moved into the ghetto and then concentration camps. Schindler builds relationships with Nazis in a position of high power. Schindler uses these relationships to start secretly planning on saving as many Jews as he can through his factory. As the Jews are being sent by trains to camps, Schindler makes his infamous list of Jewish workers he needs. The list contains men, women, and children. Schindler tries to save as many Jews as he can. Finally, the holocaust comes to an end and S... ...he end of the movie as grown adults, while Szpilman of The Pianist survived his struggle of living on the run. Both movies ended leaving the viewer with hope and fulfillment that, even though millions of Jews were killed, some managed to survive through the help of others. The movies were a representation of a horrid subject matter, which were about hope and dignity in the midst of a monstrous tragedy. The horrors of the holocaust have been seen through many points of view. In Schindler’s List and The Pianist, the directors pulled together every emotion to create a masterpiece that teaches of the dreadful acts humans can do to each other. The pain one human can inflict on another is contoured by the determination and pride of the Jews to survive. The movies present a look into what a Jew’s life was like during WWII, either by a group of people or one single man.

Goal Setting Theory Essay

The idea that human behavior is motivated and regulated by goals and aspirations has long been recognized by psychologists. Goal-Setting Theory can be traced back to Edwin Locke and Gary Latham; they elaborated on the basic notion of goal setting and have described how this drives behavior in organization. Goal-setting theory helps to explain individual differences in motivation and performance. Goals are defined as the desired outcomes in terms of level of performance to be attained on a task rather that the desire to take specific section (Muchinsky, 2005). It is thus a person’s intention to attain developed goals that can serve as a principal determinant of motivation. For instance, as a student I have a goal of attaining an A grade on this subject which would motivate me to study well and participate more in class in order to achieve my goal. According to Locke, goals have motivational value for three reasons which are: goals serve to direct and focus our attention particular direction; goals help us to maintain task persistence; and the existence of goals tends to facilitate the development task strategies. Attributes of goals that make them motivating are the difficulty, acceptance, specificity and feedback to motivate performance. It has been viewed that goals that are difficult are more motivating than easier goals. For instance, a salesperson is going to be more motivated if he has a goal of making $10,000 in commission, rather than a goal of $5,000. The second attribute is the goal acceptance, wherein a person would believe that he can attain a particular goal set to him or by him. Goals are much more motivating when they are specified in a particular level of performance, example, an individual must be able to sell 10 units of apartments in the next month rather than ‘be a good salesperson’ which is very vague motivation. Attaining a goal is often a hard process; thus it is important that employees receive feedback regarding their progress and once a goal is accomplished a pleasurable emotional state called job satisfaction will be experience. Principles of goal-setting theory has been a very influential approach and one of the most valid and practiced theories of employee motivation in organizational psychology.
