Knowledge Workers and the Brooklyn Bridge 8 Essay

Knowledge Workers and the Brooklyn Bridge 8 - Essay Example engineers, namely Washington Robeling and those who worked with him, that were mainly concerned with design aspects such as knowledge of gradient, impact of erosion by water over time, angles for rafters and columns and related information. Designing and construction of a bridge requires a basic knowledge and comprehension of the many aspects constituting â€Å"optimum structural and mechanical performance.† (Fertis, xiii). In the case of a highway bridge, dynamic and vibration analysis that needs to be carried out requires knowledge of the basic properties of the materials and cables that are used to build the bridge. Such knowledge of material properties is then used in performing the static and dynamic analysis, in developing a bridge design that is safe as well as functional. The static and dynamic analysis will involve calculations to determine both static and dynamic deformations of the bridge, together with its frequencies of vibration. This will also involve conclusions to be drawn on how long the bridge span should be in order to ensure that its rigidity is maintained in a safe design. Hence a knowledge worker working on the design and construction of the bridge in Robeling’s day would also have required a basic knowledge of statics, mechanics and structural mechanics. A knowledge worker would thus need to be acquainted with basic engineering concepts in designing of bridges. Communication in those days when the Brooklyn Bridge was first built centered around personal contact, hence these were restricted to light signals and Robelais passing on his communications through his wife. As a result, workers had to possess communication skills in interacting with members of their teams, most of whom were likely to have been drawn from the same local area of New York and largely comprising immigrants. But the kind of communication systems being used in the present day is also different from those existing during the time of Robelais. Knowledge workers may

Teenage drug addicts - Essay Example A study by National Center of Education Statistics during the year 2009 found out that the main reason of this proliferating numbers of teen drug addicts is that 22% of high school teens are being provided in drugs in their respective schools (Russell, 2008). This teen population, around 45% of this part of teen population cannot see any ‘risk’ due to excessive drug use. That means lack of awareness is the dominant reason that has led to such a grave issue. Teens living in UK are also in the running. They too fall in the same category that is severely attacked by this issue of Drug Abuse. They too are falling in the trap and ruining their lives, UK’s society and the country as a whole. Teen Drug Addiction in UK – Causes, Effects and Current Trends Even after the government’s several attempts of implementing strict policies on its teen population, the numbers of ‘Teenage Drug Addicts in Britain’ are increasing at a high rate. The deaths i n Britain due to drug abuse rose from 1952 to2182 deaths in total. Before peeking into the world of Teen Drug addicts in UK, we first need to know who these drugs came into this country and ruined the lives of many people, enjoying their teenage life. In case of Cocaine, UK is considered to be the most affected country due to drug abuse in the entire world. With 2% regular users of cocaine in UK, teens living between these people will surely fall in this trap and try their first drug, and this is what really happened. With a 19million share of the cost of drugs in the GDP of UK, more than 40% of this is paid by the UK teens. These figures clearly demonstrate the scenario of drug addicts who are teenagers and are living in Britain (Plant, et al, 2010). Overview of Teen drug Addiction During the time 2008 to 2009, around 8.1% increase has been observed in the number of teen drug users in UK. In UK, drug abuse is not just an epidemic, but a plaque. United Kingdom has a long history of teen drug abuse in its regards, because it was the first ever country of European Union that was reported to see the emergence of the drug misuse. In United Kingdom, drugs are commonly supplied around the country that’s why teens cannot find difficult in finding them and becoming huge big drug addicts in a short time period. This has led to a creation of social norm about this country as now the teen population have become really open minded when it comes to use drugs openly in social gatherings (Paylor et al, 2012). The current scenario of teen drug addicts in Britain has illustrated that this issue is getting out of hand. In a European Schools Survey Project, with 42% teen boys and 39% teen girls, illegal drugs have been used. Alcohol abuse, alcohol one of those drugs widely used in teenagers in UK, is prevailing commonly in UK, and this situation is getting worse in case of girls. Professor Martin Plant, of the University of West of England said: â€Å"One of the big prob lems is that vast numbers of young people who engage in these behaviors believe that they are completely invulnerable†. Causes of Teen Drug Addiction One of the reasons of a high rate of teenage drug addicts in UK reported by this professor are poor parenting. Parents living in UK are very broad minded and don’
