People aspire of prosperity life - Free Essay Example

Sample details Pages: 4 Words: 1289 Downloads: 5 Date added: 2017/06/26 Category Sociology Essay Type Argumentative essay Tags: Development Essay Did you like this example? Is Dubai Playing It Right! Nowadays there doesnt seem to be an end to human needs. People aspire for prosperity prosperous life, a good job, a good house, to drive a well manufactured car, and even to have a huge Bank account!! These aims may be a little bit crashed because of the economic crisis that has recently hit the world. Many countries after this crisis tried to recover and rebuilt their economy and return to be stronger and face this crisis. Others couldnt do that as this economy crisis hit it very hard as this country resources are not good enough or rich enough to get over it. From the countries that were hit by this economic crisis is Dubai. Dubai is a very fast growing country economically, it is the meeting point between the East and the West, it links between western modern life and eastern hospitality. Dubai is one of the seven emirates of the United Arab Emirates UAE. There is nothing you cant find in Dubai from beautiful beaches and clear aqua blue seas to indoor activities, an underwater hotel and skyscrapers, there is never a shortage of things to do in Dubai. It has the biggest airport in the world, the largest man-made port in the world, the largest Mall in the world, the only 7 Stars Hotel in the World, the largest Skyscraper in the world and finally the largest Theme Park in the world which is about 3 times bigger in size than Disney World in Orlando !! as came in DubaiCondoProperty.com. The question is; is it a right way to become a leading economic country at this short time? People might think that it is not the best path for development; because there are some barriers. First, resources being under stress. Second, large amounts of loans leading to debts, and Third, people that might lose their jobs and companies that might shut down if the economy falls down. Don’t waste time! Our writers will create an original "People aspire of prosperity life" essay for you Create order One of the reasons that support this point of view is that any developing country it should have enough resources for investment especially if we are talking about the UAE, many of these countries contain Oil resources except Dubai This city state is purely a business city wholly depending upon tourism and other business. Dubai World, attract world entrepreneurs that started spending more and more on building fine roads, and 7 Star Hotels. Prasadjain said in an article entitled Financial crisis in Dubai, reasons and effects. So Dubai is not an Oil Country and depend mainly on money that it earns from these investments especially tourism sector. But immediately after this economic crisis a rumor spread that after the Atlantis opening ( which cost about 1.5Bn Dollars ) the hotel was only charging 10 percent of the original price and has only about 26 percent occupancy as mentioned in Diversification Dubais Downfall by Helena Axelson Fisk. Also it was published that Dubai began to pro nounce a plan for building two more villages like Al Nakheel (Palm Island) which is a group of Islands on the shape of a Palm that cost about 110Bn Dollars before it was even completed! As published in BBC News website. Huge investments surely need massive amount of money, this condition is not available in Dubai, it tend to Borrow money from Banks all over the world, leading to debts then failure to repay. UAE faces up to $184 Billion total debt according to estimates by Bank of America Merrill Lynch, also the Bank said that Dubai only faces almost $50 billion of debt amortization in the next three years: $12 billion in 2010, $19 billion in 2011 and $18 billion in 2012as mentioned by Sebastian Tong in article entitled UAE faces up to $184 billion total debt: BofA-Merrill Lynch. Also there are many Banks that were hit because of Dubai inability to repay Banks were hit particularly hard on concerns over Dubais ability to pay back its debts as came on BBC News, some of these Banks are Barclays which was the biggest faller down by 8%, followed by Royal Bank of Scotland, which lost 7.8%. Dubai asked for a six-month delay on debt repayments it was due to repay $3.5Bn in December. Other reason that strengthens my position is that a fast economic growing country should have a strong market study and economic plan to preserve peoples jobs as when it falls down, people might lose their jobs and companies might shut down, thats what happened in Dubai when it was hit by economic crisis. Nowadays a lot of people were fired and lost their jobs because companies couldnt pay them. Lots of people have left my neighbor, an architect from the US, was fired and her whole company was shut down. A western journalist said as mentioned in BBC News. Other witness to these incidents A lot of our friends have lost jobs, particularly senior management in human resources and information technology, some have stayed here, but others have left, says Grace, in an article by Michael Buchanan. It reached that people leaving Dubai and parking their cars in the airport. On a recent walk around the car park at Dubai Airport, there were more than two dozens cars that looked completely aba ndoned by their owners. Some people wrote little messages on the layers of sand that have gathered on the vehicles. One says Gone 4 Ever, and another says He will return Inshallah This was mentioned by Michael Buchanan as well. Concerning losing jobs as well Buchanan mentioned that The competition for jobs is fierce now, whereas there would be two people for one job before, I think there is ten now. The opportunities arent there as much and the salaries arent there. Its just getting worse and worse! On the other hand, some people might disagree with this point of view and assure that Dubai will make it and survive peacefully from this economic trap as Abu Dhabi; Dubais Twin has just lent it $ 10Bn to repay her debts as mentioned by Margaret Coker in an article entitled Dubais Rescue Boosts Others. But it would be the same and the circle would not stop as its going to be a Series of Debts. Finally, Dubai should take step by step in her economical growth and not jumps, plus its not the top needs of citizens to have this luxurious fantasy life, by this amount of money Dubai might have done many important projects to help the 3rd World Countries, these amounts of money can be charged to many productions that might aid the needs of people all over the world.

Effective School Leadership Free Essays

Effective School leadership today must combine the traditional school leadership duties such as teacher evaluation, budgeting, scheduling, and facilities maintenance with a deep involvement with specific aspects of teaching and learning. Some key elements of Instructional leadership and what I believe to be most important and effective elements in the leadership role include the following: Prioritization: Instructional Leaders make adult learning a priority and set high expectations for performance (NAESP, 2001). While leaders cannot neglect other duties, teaching and learning is where the majority of a leader’s scheduled time needs to be allocated. We will write a custom essay sample on Effective School Leadership or any similar topic only for you Order Now Visible Presence: Placing the focus on learning objectives, modeling behaviors of learning, and designing programs and activities on instruction are essential for instructional leadership (Whitaker, 1997). Having leaders as teachers of instruction serves as a model for many teachers who may struggle with certain concepts and can help build trust and relationships. Curriculum: Principals need to know about the changing concepts of curriculum (Approaches to Leadership). The goal of any leader should be to increase student achievement; therefore, the curriculum, instruction, and assessments must all be aligned with the standards. Leaders need to be knowledgeable with curriculum and state standards and provide professional development and continuous learning for adults. Data: In their focus on improving achievement, effective leaders use multiple sources of information to assess performance (NAESP, 2001). Many leaders use data to help guide the instructional focus and professional development for teachers. Effective leaders skillfully gather information that determines how well a school organization is meeting goals and use that information to refine strategies designed to meet or extend the goals. Effective leaders make student success pivotal to their work and,  accordingly, pay attention to and communicate about instruction, curriculum, and student mastery of learning objectives, and are visible in the school. Learning needs to occur throughout an organization, and instructional leaders need to become participants in the learning process in order to shape and encourage the implementation of effective learning models in their schools. To illustrate, effective leaders don’t just arrange for professional development; rather, they participate in staff training provided to their staffs. Additionally, good leaders foster the idea of working together as a valuable enterprise because they understand that this kind of collaborative learning community ultimately will build trust, collective responsibility, and a school wide focus on improved student learning (Mendez-Morse, 1991).

Supercomputers Molecular Dynamics

Question: Discuss about the Supercomputers Molecular Dynamics. Answer: Introduction A supercomputer can be defined as the computer with very high level of computational capacity when compared with the general purpose computer. The term supercomputer was coined in 1929 at New York for a set of large customized tabulators (Chen et al., 2014). The set of tabulators was made by IBM to support the activities in Columbia University. However, the supercomputers were introduced in the late 1960s. Seymour Cray working at Control Data Corporation built it. The early supercomputers used only few processors. The development of the supercomputers made it evitable for incorporating thousands of processors in the end of 1990s. The count of processors reached to tens of thousands in the multiple parallel supercomputers developed at the end of 20th Century (Shaw et al., 2014,). The performance of the supercomputers is measured in floating point operations per seconds or FLOPS. The latest supercomputers have performance capacity of up to quadrillions of FLOPS. The following assignmen t has been made for analysis of the supercomputers and their structure and benefits. The study would help in evaluating the various components of the supercomputers and description of any one of them. The assignment would also highlight some innovative trends that may be possibly seen in the near future of supercomputers. Major components of Supercomputers The supercomputers are very useful for solving highly calculative intensive tasks that have complex structure and operations. These complex operations include simulation, modeling, analyzing various types of data, cryptographic analysis, and intricate designing (Sridharan et al., 2013). The operations of supercomputers are helpful for weather forecasting, simulations of molecules behavior, and modeling of airplanes within wind tunnels. The analysis of data finds its use for the security agencies, astronomical data manipulation, and sequencing of the genome. The architecture of supercomputer consists of processors, memory, input and output devices, and interconnection. Processors: The processors used in supercomputers are completely made up of pure silicon. The pure silicon consists of 99.99% silicon crystal and it is more costly when it is compared to gold in weight to weight (Liao et al., 2014). The size of silicon crystals are approximately 300 square meters. The processors consist of doping materials that helps in formation of wires, resistors, transistors, and capacitors. The components of doping materials also consist of rare elements of earth and their quantity is in minute volumes. Memory: The memory used in the supercomputers is distributed in nature. Each processor of the supercomputer has been connected to an exclusive local memory with an network interface node NI (Hord, 2013). The dedicated communication network is useful for connecting the nodes of the supercomputer. NORMA or no remote memory access is implied in the system for forming no global cache coherent shared memory address. Input Output devices: The input output devices are helpful for inputting the devices into the system and making allowance for the output of the value. The input and output functions of the supercomputers have same concept of operations like in general computers. It includes devices for entering the values/data in the system for processing and devices used for displaying the output of the processed data (Bartolini et al., 2014). The various input devices like keyboards, reader, or microphone would act as the input devices for the supercomputers. The output devices mainly include the display monitor and printers. Interconnections: The interconnection consists of a network subsystem in the supercomputer for targeting memory intensive applications of supercomputers (Anwar-Mohamed et al., 2014). The supercomputers are integrated with many nodes for the high performance of the network operations. The interconnection design of the supercomputer is based on the 64X64 high radix crossbar switches. The design of the interconnection depends upon the traffic amount, communication pattern, and physical constraints. However, there are probabilities of finding the bottleneck of the communication design for further enhancement and improvement of the performance. The supercomputers are designed for scaling up of the entire system along with the computer performance (Rohr et al., 2014). The design space exploration of the computer devices is responsible for the evaluation of the feasibility of the networks. The complex architecture of the supercomputers makes them very complex from other standard computers. The characteristics differences between the standard computer and the supercomputers are specialization, controlled environment, operating system, hierarchy of memory designs, and programming language. Discussion of Distributed memory system of Supercomputers Distributed storage memory is very crucial in the structure of supercomputer. The parallel algorithm has been implemented in the structure of supercomputers. The processes by which the parallel algorithm can be implied in the structure of the supercomputers are 1 shared memory systems (uniform memory access UMA and cache coherent non uniform memory access ccNUMA) and 2 distributed memory systems (massive parallel processing and cluster computing) with each of them having a standardized programming model (Stephan Docter, 2015). The memory system of the supercomputer is of hybrid structure with shared and distributed architectures. The memory system shares the same address space or memory at low level of computation nodes. Numerous storage appliances are used for forming the backbone of the new storage system that would be capable for the storing, ingesting, distributing, and processing of the research data at a rate of one terabyte per second. The use of flash drive has made the data processing more easy and comfortable (Zgurskaya Smith, 2016). The processing of the data has been largely improved and it has resulted in formation of the faster throughput of the data. The solid state devices used in supercomputer are prone to store the data on the flash memory chips instead of the magnetic platters that were used in hard drives. The solid state devices do not require any movement and it has made the system less rugged and vulnerable for the failure. The devices of solid state do not consume much energy and are classified as less power hungry devices. The speed of data processing is almost similar to ten times of the computer system of NAS system. The storage system comprises of 40 Peta-bytes of unprocessed data storage that can hold almost about 227000 miles of the books stacked to each other (Rohr, Neskovic Lindenstruth, 2015). The performance of the supercomputers is measured in floating point operations per seconds or F LOPS. The latest supercomputers have performance capacity of up to quadrillions of FLOPS. The supercomputers have incomparable increased value of the computational efficiency that can deliver more optimized performance with predictive models of the computerized storage. The 40 Peta bytes of storage are comparable to 40,960 computers with 1 Tera bytes of storage each (Ellingson et al., 2014). The supercomputers are built with high solid state drives for memory system. It would help in solving the problems of the computation faster than the systems that incorporates the traditional hard drives. The supercomputers are designed for scaling up of the entire system along with the computer performance. The memory used in the supercomputers is distributed in nature. Each processor of the supercomputer has been connected to an exclusive local memory with an network interface node NI. The dedicated communication network is useful for connecting the nodes of the supercomputer. The complex architecture of the supercomputers makes them very complex from other standard computers (Zgurs kaya Smith, 2016). The characteristics differences between the standard computer and the supercomputers are specialization, controlled environment, operating system, hierarchy of memory designs, and programming language. Future trends for Supercomputer technology The development of technology has been increased and it has seen abrupt pace of increased potential. The technology that has been largely innovated since the last decade is the Supercomputer technology (Stephan Docter, 2015). The supercomputer technology has seen wide development of the implementation models. Some future trends of technology that can be used in supercomputers include: Increment of power and performance: The Moores law has presumed that the technological development of the integrated chips has seen large increment in power generation. It can be predominantly said that after a span of 24 months, the overall capacity of the computer chips would be doubled (Anwar-Mohamed et al., 2014). The increment of the power of processors would result in increasing the processing speed and efficiency of the chips. The use of improved ICs for the CPUs of the supercomputers would help in increasing the overall processing efficiency of the device. Deployment of the cloud function: The latest trend in storage and memory is the application of mobile cloud services (Hord, 2013). However, the cloud server can provide the space up to 10GB. The development of technology would be helpful for increasing this limit and integrate the cloud system with the operations of supercomputers. Conclusion The completion of the assignment had helped in realizing that the supercomputers have developed since the last three decades and the technology had made it evitable for incorporating tens of thousands of processors in the supercomputers. The latest supercomputers have a performance capacity of up to quadrillions of FLOPS. The supercomputers had achieved the qualities of solving highly calculative intensive tasks with complex structured operations. Some of the complex operations include simulation, modeling, analyzing various types of data, cryptographic analysis, and intricate designing that had been widely used for weather forecasting, simulations of molecules behavior, and modeling of airplanes within wind tunnels.
