Development of Railways and it's impact on the society Essay

Development of Railways and it's impact on the society - Essay Example 1). This paper studies the factors causing the growth of railways in Europe and its impact on the society. The birth of railways happened in the year 1767 when the iron rails were laid for the first time ever at Coalbrookdale. The early railways were used in the French Wars that were carried out between 1790s and 1800s. At Pen-y-Darren, in the year 1804, the Trevithick’s Wylam locomotive was used which was one of the first forms of railway. Four years later at Euston, the Trevithick’s Catch-me-who-can was used. The Blenkinsops rack locomotive and the Hedleys Puffing Billy were introduced successively in the years 1812 and 1813 respectively. The Stephenson’s Blocher was used in 1815. Stephenson created the Stockton to Darlington railway line that was 27 miles of 4 8Â ½" track in the length was opened in the year 1825 (historyhome.co.uk, 2011). The first passengers were carried by the Locomotion 1. Joseph Hall in 1825 developed the Cort’s puddling process as well as the rolling process. Coke was replaced by coal with the hot blast method proposed by Neilson in 1828. The 30 miles long railway line leading from Manchester to Liverpool was commenced in the year 1830. In 1833, a railway line for the transportation of coal was started from Liecester to Swanington. Daniel Gooch engineered the project of the London – Bristol line construction. The Isambard Kingdom Brunel undertook this project in 1835. This marked the beginning of the Great Western Railway that was completely flat over a length of 85 miles. The London - Bath – Briston railway line and the Birmingham to London railway line were started in 1838. Till the year 1838, the total length of railway lines that had been made was 500 miles. In just a matter of ten years till 1848 the growth of the railway became so rampant that the total length of railway lines increased from 500 miles to 5000 miles.  "The

Gun Control and Crime Problem in the US Research Paper

Gun Control and Crime Problem in the US - Research Paper Example Gun control has always been a very debatable and a complex topic, law-abiding citizens are expected to follow the law but these days law has become a donkey on which the rich people ride. In several Asian countries people get away with gun crimes because of their influence and authority, there have been several cases in the US also wherein the guilty have gotten away with heinous crimes. There are many who just cannot handle firearms safely and it is quite obvious that firearms are not meant for those individuals. It is also a fact that firearms can be used for protection and guns can be useful provided they are in the hands of right individuals but it is very difficult to determine who is right and who is not became many a time the so called right people end up doing wrong things. This is exactly why this topic is very debatable and complex. Mental illness is also a very big factor when it comes to gun control, mentally ill people can easily go and purchase guns and run riot in the street, the very same happened in Norway a few months ago, a mentally ill person had easy access to firearms and the same resulted in a massacre. It is extremely important to place restrictions but this is something which is implausible, there are hardly any laws when it comes to purchasing a firearm, yes, one needs a license to obtain it but everyone these days is fully aware of the fact that licenses can easily be obtained by bribing officials and this is especially true in several Asian countries.

Is Citizenship in Australia Simply an Individual's Legal Status Essay

Is Citizenship in Australia Simply an Individual's Legal Status - Essay Example The study will examine the benefits and awards that accompany being an outstanding Australian citizen. Precisely, the study seeks to explore the fact that citizenship is not just a legal status since there is more to it. Citizenship in Australia can be regarded as a legal status in a number of ways. Australian citizenship came into being 26 January 1949 under the Nationality and Citizenship Act of 1948. Before the act, Australian citizens used to be British subjects; they shared a nationality code similar to that in Britain. One of the ways through which a person can become an Australian citizen includes citizenship by birth. In this case, a person becomes an Australian citizen if born before 20 August 1986 or when a person was born after that date, but one of the parents held Australian citizenship (Davis, 1996, p. 76). Legally, a person can also be considered an Australian citizen if born overseas and one of the parents held citizenship of Australia at the time of birth. Moreover, people are eligible to become Australian citizens if they were British subjects residing in Australia for 5years before 26 January 1949. Apart from the fact that Citizenship in Australia is a legal status, it can also be considered a privilege which offers numerous rewards. ... The Young Achievers Award has some objectives which include acknowledging and highlighting the achievements of young persons in Australia. The award also strives to use examples of youth achievement with the ultimate aim of educating the general public. Moreover, the award aims at motivating and encouraging young Australians at all levels in their respective fields (Maton, 1995, p. 41). In a way, the Young Achievers Award helps the young citizens to develop some pride in being citizens of Australia. As a result of the award, Young Australians have the opportunity to build self-confidence, since the rewards enhance excellence. Young citizens receive this award as a way of providing mentors and role models for youth by noticing the pursuit of excellence and the achievements of young people. Moreover, the Young Australians Award has an objective of priding good citizens by encouraging and developing life skills and leadership skills among the youth (Dutton, 2002, p. 17). Another popular award given to Australian citizens includes the Regional Achievements and Community Awards. The award is common in areas of Victoria, New South Wales, Queensland, and Western Australia. Citizens in these regions seek this award with a lot of determination. The award aims at encouraging and paying tribute to individuals, groups, businesses, and communities who make significant contributions to the rural and regional areas. Therefore, the award aims at encouraging those people working in rural areas with an aim of enhancing and supporting commercial, economic, social, and environmental prosperity. This award plays a significant role in recognizing citizens who work extremely hard to develop their respective fields and the

Decision making models Outline Example | Topics and Well Written Essays - 1000 words

Decision making models - Outline Example The essay will also attempt to identify the legal requirements relating to the collection, use and storage of data and information in the UK. Basically, the term decision making is used to describe the act of seeking information, interpreting that information and based on such perceptions, arriving at a conclusion in relation to strategic issues that affect the organisation (Simons & Thompson 1998:7 as cited in Schultz et al 2004). Vroom-Yetton- Jago’s normative decision making model is mainly based on the notion of taking people off their primary tasks in the organisation to participate in teams or other decision making activities and this may be a good gesture with regards to empowerment but it may also be costly as well if it is unnecessary (Vroom & Jago1988). Thus, the Vroom-Yetton-Jago model is a decision making model that gives the opportunity to the leader to first examine the situation then come up with an ideal style or level of engagement that can be adopted in the o rganisation. ... The leader also ought to have enough information about the problem as well as to be in a position to identify the structure of the problem. The leader will also need to be in a position to establish the probability of the level of commitment by the subordinates and their wish to share the same vision in the organisational goals that can be attained through problem solving. More importantly, the leader also ought to be in a position to identify any conflict that may exist and the level of information possessed by the subordinates that can be used to make sound decisions that will be beneficial to the organisation as a whole. Having gathered all the information using the above mentioned method, a leader can adopt any of the following decision making style depending on the nature of the decision to be made. In autocratic one, the leader can solve the problem using readily available information to him or her whilst in autocratic two, he or she may get additional information from the grou p members then make the decision alone (Vroom & Jago1988). Though different, these leadership styles show that there is an element of individualism in the leader in decision making. In consultative style one, the leader solicits for information from individual members in the group and makes a decision alone whilst in consultative two, the leader collectively shares the information with all the members of the group but will make the decisions alone. Again, in this case, there is an element of the leader making a decision alone after gathering information from the other members of the group. Finally, in group two, decision making is collective whereby the leader engages all the members of the group then they will make a decision as a group whereby the leader

Is it over-ambitious to expect spatial planning to deliver better Essay

Is it over-ambitious to expect spatial planning to deliver better health - Essay Example started developing sewer systems in all cities in order to address the outbreak of epidemics such as cholera, influenza and tuberculosis (Jackson 2011, p 23). In the last two decades, there has been considerable interest in the relationship between the fields of urban planning and public health in order to address the major health concerns (Greed, 1999, p 9). Currently, the role of government in urban environment and city planning has been critical in enhancing the health of population since city planners issue built environment regulations and zoning laws that determine the design of the infrastructure, sewer systems, roads, public spaces and social amenities in the neighborhoods (Boone and Modarres 2009, p 30). Spatial planning leads to better health and sustainable communities. Planning concepts such as Spatial Urban Health Equity Indicators (SUHEI) allows the urban planning authorities to determine the relationship between exposure to health hazards and health effects. The initial goal of planning was to offer healthy living conditions for the growing urban populations, but recent planning efforts focus on the importance of space and place in the communities (Cullingworth and Nadin, 2006, p 9). According to environmental research, the surrounding social, biological, chemical and physical factors determine the quality of health of an individual since factors such as unemployment, unsafe neighborhoods, noise and radiation negatively affect the health and wellbeing of an individual. The Driving force-Pressure-State-Exposure-Effect-Action (DPSEEA) model outlines that driving forces push the environmental factors that that ultimately pressure the environment through human exploitation thus exposing human beings to conditions that turn out to be environmental h azards (Jackson, 2011, p 13). The Multiple Exposures-Multiple Effects (MEME) model outlines that contextual factors such as economic development, demographics and social conditions influence the exposure to

Referring to Data in Aspect 2 3 of Data Collection and Processing, we can see there were 5 single replacement reactions, and 4 double replacement reactions (one of which was a neutralization reaction). The reactions involving an element and a compound were all single replacement reactions, and the reaction involving two compounds were double replacements (which included a neutralization reaction). Aspect 2: Evaluate the Procedure: A problem with this procedure is that it doesnt explore all types of chemical reactions. Also, try as one may, it is sometimes difficult to get the residue of a substance off the spot plate. This tampers with results. Aspect 3 Improving Experimental Design: A few more reactions should be added where simple composition and decomposition are shown. Also, using the Bunsen burner, a reaction should be added where hydrocarbon combustion is shown. Disposable spot plates should be used, to ensure that residue left by previous reactants and reactions, do not tamper with results.

Dynamic Systems Development Methodology

Dynamic Systems Development Methodology Dynamic Systems Development Methodology is a methodological analysis used by information system professionals to develop softwares projects which is originated from Rapid Application Development Methodology. Stapleton (1997) states that â€Å"DSDM describes project management, estimating, prototyping, time boxing, configuration management, testing, quality assurance, roles and responsibilities (of both users and IT staff), team structures, tool environments, risk management, building for maintainability, reuse and vendor/purchaser relationships all in RAD environment.† It is based on the nine principles and considered as one of the agile project management techniques that deliver the software systems on time and within the budget. The above methodology is applied to the Yojimbo Supplies Ltd in order to produce the customer-order system which covers the customer details, order details and stock control details. At present only the part of the company operations is computerised and the remaining is still done by the paper work ever since the company has started. After carrying out the brief analysis, the proposed system must be implemented with a centralised database over a local area network. The personal involved are Project Manager, Programmers, System analyst and facilitator. Below describes the project plan that involves phases, stages and tasks of DSDM in context with the case-study. Phases of DSDM: Feasibility Study Business Study Functional Model Iteration System Design and Build Iteration Implementation Feasibility Study:   Ã‚  Ã‚  Ã‚  Ã‚  It is about whether the proposed method can be applied or not and thorough research is carried out to find out the existing problems. Feasibility study has already been carried out for the Yojimbo Company with the interview transcripts provided which shows that there is no software which is integrated together and need to produce a system that is efficient to use. Business Study:   Ã‚  Ã‚  Ã‚  Ã‚  It is about acquiring a clear understanding of the business flow and how the processes are related to each other. It involves identifying the stakeholders and those who are involved in the project. There are two stages involved in this phase. Arranging JAD workshop It involves meetings with the stakeholders by making special arrangements for time and location. The activities involved in the JAD workshop are discussing the requirements with the Managing Director, Financial Director, Sales Manager and Warehouse Manager of the Yojimbo Supplies Ltd. Then the next activity involved is to analyse the requirements where the system boundaries and sub-systems are identified by the requirements identification to produce the final rich picture and CATWOE which is done by the system analyst. Yojimbo Supplies Ltd is divided into three sub-systems. They are Buying and importing, Stock and Delivery, and Selling and Marketing. The final activity is to produce a final project plan by identifying the resources and creating a timeframe. Produce a Business Study Report In this phase the first activity is to identify the business processes and to produce data flow diagram which involves context diagram, document flow diagram, physical and logical diagram and finally producing the entity relationship model that is implemented in the logical design of the database. The next activity is Systems architecture definition that describes the development of the target platform and to identify the major system components and finally prioritising the requirements of the system using the MoSCoW (Must to be done, Should have it worked but not completely depend on it, Could be left out if necessary, Would have it in the future) principle. The final activity involved in the Business study is to outline the prototyping plan i.e. to define the prototyping strategy to be used in subsequent phase and the configuration management plan. Functional Model Iteration:   Ã‚  Ã‚  Ã‚  Ã‚  It works on refining high level business information requirements and functions of systems identified during the business study of the methodology. In this phase risk has to be identified and recognize a plan on how to deal with risk for future developments. The outcome of the functional model iteration is standard analysis model of the software. Five stages are involved in this phase. Rectify Business aspects In this phase the activities involved are high-level functional and information requirements are refined Identify functional prototype The first activity is to analyse the requirements of the dataflow diagrams and list the requirements of the current iteration and to identify the non-functional requirements that were recognized during the previous stages and create the functional model that identity the major functionality of the system components. Agree Plan To determine the time for the design development of the system and finally agree the prototype that is finalised with the clients. Create functional prototype It is an iterative process until the desired result is obtained. At first the plan in implemented by creating the functional prototype that represent the functionality of the system and then individually created functional prototypes are merged together to refine it according to the remarks given by users and if any changes are required it can to be done in the next iteration. Review Prototype Testing the produced functions of the system and reviewing the functional model based on the user comments and the final functional model is delivered. System Design and Build: In this phase the actual system is built based on the non-functional requirements carried out in the previous phase and the built-in system is implemented in the next phase once the testing is done. Identify Design Prototypes The main activities involved in this task is to identify non-functional requirements and implement the plan. Agree on Prototype Design Agreeing the prototype Design by prioritising the design requirements of the system. Create Design Prototype In this task the design prototyping takes place where the components of the system that must have is built and review the produced components and at last testing of the designed prototype is done before it is handed over to the users. Review Design Prototype The last activity in System Design and Build phase is to test the system as a whole rather than unit testing and check the performance and also to deal with system in case of any event failure.   Ã‚  Ã‚  Ã‚  Ã‚  Implementation:   Ã‚  Ã‚  Ã‚  Ã‚  This is the final phase in the methodology where the built-in system is moved into the production environment from the developed environment. In context to the Yojimbo Supplies Ltd the created centralised database package is installed on the server and make sure that each and every system will be able to access the database and all systems are connected with each other through local area network. System Implementation Implement the hardware and software of the system on site and handing over the system to the company. Review Business The project Review Document reviews the achievements during the development process in relation to the requirements. User approval and guidelines The system will be approved by the end users and user manual is produced where the precise details of the implemented system is given so that the end-users can use it to refer for any help. User Training Training the users on how to interact with the new system at the location. Advantages of the DSDM: Provides a technique-independent process Flexible in terms of requirement evolution Strict time and budget adherence Incorporates stakeholders into the development process An emphasis on testing is so strong that at least one tester is expected to be on each project team. Designed from the grounded up by business people, so business value is identified an expected to be the highest priority deliverable. Has specific approach to determining how important each requirement is to iteration. Sets stakeholder expectations from the start of the project that not all requirements will make it into the final deliverable. Disadvantages of the DSDM: Involves progressive development of requirements Focus on RAD can lead to decrease in code robustness Requires full commitment to DSDM process Requires significant user involvement Requires a skilled development team in both the business and technical areas Probably the most heavyweight project compared in this survey. Expects continuous user involvement Defines several artifacts and work products for each phase of the project; heavier documentation. Access to material is controlled by a consortium and fees may be charged just to access the reference material.
