Guidelines of small hydropower development dealing with environmental protection were sug- gested hereby. Various specific technical environmental solutions focusing on small hydropower development applied in European and other developed countries were also introduced in this paper. Main environmental solutions are discussed as follows： integrated design should be advocated during plan/design stage,＂ ecohydraulic engineering and its utilization in SHP design and construction; effective technical approaches to relieve and eliminate the impact of river interception and fix the reasonable minimum biological flow; environment-friendly mitigation and compensation measures for high/low-head hydropower schemes applied in diversion works, intake, nature-like fish-passes, penstock and powerhouse design; study and application of the new technology, material and equipments; launching renovation of environmental protection in existing stations; emphasiz- ing public participation and their acceptability for the SHP environment; coordinated inter-disciplinary study at national level, etc. Two case studies in Sweden and Australia are given here.展开更多

In order to achieve this goal, I have used several critical theories of authors such as： Michel Foucault, Carl Jung, and Pierre Bourdieu. The analysis is concerned with exploring the alternation between the themes of freedom and imprisonment and the way in which these issues influence the evolution of the main character. I argue that the two themes are in a relation of interdependency and they can be interpreted as opposites from a rational point of view. The rational point of view, although valuable, is, however, incomplete without the exploration of the emotional and subjective factor. This factor can account for the ＂unreasonable＂ events from a broader perspective： that of the imagination. As Michel Foucault argues, power exists only in action. Power is also a rather elusive concept. In the same way, the perception of reality can be represented more accurately from a subjective point of view. More exactly, reality is constructed with every thought, emotion, and action of the individual. To sum up, I argue that, from a sociological point of view, the main character is striving to assimilate his personality in a new and hostile cultural environment. On the other hand, from a psychological point of view, he is confronting his inner shadow, as Carl Jung defines the hidden part of the personality. This has a result of the emergence of a genuine sense of self. As the critic Pierre Bourdieu argues, there are a set of common characteristics of taste which define the social belonging of an individual. In the analyzed novel the character manages to adapt to the new situation and to overcome the obstacles that he finds on his way.展开更多
