Professor Kyle Loughman English B1A – Online 23 September 2014 Multithreading and House‚ M.D. Johnson’s idea of multiple threads in watching television fundamentally lies in his overarching theory called The Sleeper Curve. A thread is a strand of information in one scene; a scene can have up to ten threads increasing the complexity of the show. Multithreading is “keeping [these] densely interwoven plotlines distinct” (Johnson 63). In comparison to earlier television shows that only followed

Kyoto´s Protocol signed by European Countries in 1997 made Eurozone commits itself to reducing their CO2 emissions by 5% (referred to 1990 figures) [1]. In order to achieve such a reduction all countries were forced to their own abatement figures and also to incorporate environmental policies to their legislations. The EU Commision´s 2007 and 2008 communications and proposals were the basis of Directive 2009/28/EC where Strategy 2020 was established. The basic core of this strategy is 20/20/20:

The Environmental Kuznets Curve for Sulphur Emissions Statement of the Problem In recent years‚ as increasing concerns about various environmental issues‚ there are a great number of studies focusing on this topic. One of the most popular approaches is to detect the relationship between pollution level and socio-economic development. This paper will address the problem of whether or not we can find empirical evidence for the environmental Kuznets curve for sulphur emissions. In other words‚ as
