Les perturbations créées par l'exploitation forestière affectent la biodiversité. Certaines espèces s'y adaptent, tandis que d'autres se voient menacées. Les exigences distinctes d'orchidées des vieilles forêts, spécialement les Goodyera, les rendent particulièrement vulnérables. Pour assurer leur conservation ainsi que celle des milieux spécifiques qui les abritent, leur microhabitat et la distribution de leur abondance dans des peuplements régénérés après des perturbations naturelles et sylvicoles ont été étudiés. L'étude a été effectuée en Abitibi dans la sapinière à bouleau blanc de l'ouest du Québec. Une chronologie de dix peuplements naturels régénérés 41 à 245 ans après feu a été échantillonnée ainsi que des sites de coupes pré-industrielles (neuf coupes partielles non mécanisées de 40 et 60 ans) et industrielles (cinq coupes totales de un à vingt ans, six coupes partielles et vingt îlots (~250 m²)). Goodyera colonise préférentiellement les microhabitats aux caractéristiques qui se bonifient avec le temps dans la succession forestière de peuplements mixtes, telles que la présence de bois mort décomposé au sol (peuplier?) avec de la mousse, un recouvrement d'espèces herbacées peu élevé, un rapport C/N élevé, la présence de litière d'aiguilles et un pH acide. L'abondance maximale des Goodyera a été observée dans les vieilles forêts naturelles. Aucune présence n'a été décelée suivant les diverses interventions sylvicoles industrielles. Goodyera ne semble pas tolérer les perturbations reliées à l'aménagement forestier, même les moins sévères. Elle pourrait conséquemment être utilisée comme indicateur pour établir une règle de « filtre fin » afin d'identifier une partie du territoire à protéger pour assurer sa conservation et celle des écosystèmes des vieilles forêts où elle est fortement représentée. ______________________________________________________________________________ MOTS-CLÉS DE L’AUTEUR : Vieille forêt, Conservation, Espèce indicatrice, Filtre fin, Bois mort.

Taitung County is mountainous. Its geological structure is weak. Typhoon and heavy rain is frequent. Land erosion, landslide, and silt deposit in rivers is serious. In recent years, hilly areas are over-developed and conservation problem worsens. In typhoon and heavy rain, soil and other resources would be washed away and causes serious damage. The resources that people are relying on are vanishing. The purpose of this paper is to study the conservation of hilly areas, the management of river catchment areas, and the investigation and planning of the conservation of resources. This paper may help our people better understand the importance of conservation and t hey will be willing to work for a better Taitung Countye. This paper also studies the government conservation policies over the years and the their results, the farmers¡¦ understanding of the land, and conflict between the government and the farmers in land use in hilly areas. The study finds out that in managing the river catchment areas, government executive system is too complicated. Farmers do not appreciate the way the laws are implemented. They do not admit that their development cause water pollution or soil erosion. Rather, they believe that landslide and government policies in garbage dumping and road opening are to be blamed. Farmers are against most of the government policies especially in returning their land to government. There is a gap between government and farmer recognition. It is suggested that from now on, related personnel should investigate more and communicate more with people before preparing a policy. And since farmers are more willing to accept policies in subsidizing afforestation and soil protection, government should work on these issues.

To align firm strategy with the changing environment has always been a challenge for executives. The business literature consists of different perspectives on how to solve the problem and whether to resist change, adapt or do both at the same time. Each got their own implications, inertia could lead to rigidness, adaptability might negatively influence reliability and ambidexterity is seen as a combination of both. The core is exploiting present capabilities meanwhile exploring future opportunities. To study these notions we have conducted a cross-sectional study including four Swedish service-firms which operates in either a stable or dynamic environment. Executives were interviewed and asked to elaborate on their strategies. By doing this we were able to construct a model who suggests when to adapt, when to resist change depending on environmental stability. We also observed that capital- and knowledge-intensity has been somewhat neglected in previous research and could be studied further.

This thesis focus on the growing problem of elder mistreatment in the United States and related risk factors. In particular, focus is given to the problem of elder financial exploitation using survey analysis of an urban adult sample in the United States.

This study contributes to nascent entrepreneurship research by investigating factors on the individual and opportunity levels of analysis that determine the exploitation of innovative venture ideas. As a result of the literature review three theoretical perspectives were chosen to organize the factors: human and social capital, entrepreneurial self-efficacy, and domain definition strategy. The analysis of the chosen factors is based on hypotheses formulated on the basis of the literature review concerning the impact of the factors on the performance of nascent entrepreneurs during the discovery process. Empirical data were collected from the survey of 409 nascent entrepreneurs who addressed a public advisory agency in Stockholm area. Research findings show that among all factors, statistically significant predictors of exploitation of venture ideas are social capital in terms of the contact with counselors and number of ties with different actors, planning and marshaling self-efficacy, initial investment, tangibility and innovativeness of the future offerings. As for the direction of relationships, too many ties with different networks and higher planning self-efficacy influence exploitation in a negative way. Among variables related to domain definition strategy, entrepreneurs with innovative venture ideas based on services have higher probability of exploiting their ideas. Those who have made initial investment into the development of venture ideas and have a frequent contact with counselors are more likely to continue exploitation efforts. Of five dimensions of entrepreneurial self-efficacy, higher marshaling self-efficacy was shown to positively contribute to the exploitation process. It is especially difficult during the early stages of entrepreneurial process to predict which venture ideas will survive, thus, nascent entrepreneurship assistance should encourage experimentation. Although it is difficult to make generalizations from the study about nascent entrepreneurs in the Stockholm area, it can be advised to encourage the development of new services and enhance the entrepreneurial potential of nascent entrepreneurs by developing their entrepreneurial self-efficacy, especially marshaling self-efficacy.

In this dissertation, Foucault’s methodologies, archaeology and genealogy, are used to explore the links between silence, knowledge and power in the area of therapeutic sexual exploitation. Underpinning this task is Foucault’s theoretical assumption that knowledge is not scientifically constructed through objective and rational methods. Knowledge, under Foucault’s theoretical framework, is influenced by the more obscure conditions of possibility which affect power relations and, therefore, power-knowledge. Therefore, New Zealand’s scientific discourse around therapeutic sexual exploitation is analysed by moving between the discursive and the extra-discursive. This is undertaken to highlight the more obscure conditions of possibility which may have affected the political construction of knowledge and its material effects in the area of therapeutic sexual exploitation. New Zealand’s academic discourse on therapeutic sexual exploitation is examined with reference to the social conditions which have influenced the origins of counselling and psychotherapy in New Zealand. This includes an exploration of the links between counselling and psychotherapy to other New Zealand based psy-professions. In particular, an investigation is conducted as to how disciplinary procedures have been applied to those connected to, and affected by, therapeutic sexual exploitation. This, however, is studied by locating New Zealand’s discourse within an international discourse on therapeutic sexual exploitation. This wider lens shows how New Zealand’s discourse around therapeutic sexual exploitation, as other countries’ discourses on this matter, has developed in response to local social conditions and changing power relations. Through this broader analysis of New Zealand’s discursive formation on therapeutic sexual exploitation one can see the interplay between silence, knowledge and power, and its material effects on the lives on people. This dissertation highlights not only what knowledge-power might be restricting, but also what it might be producing in the area of therapeutic sexual exploitation, the impacts of which, it will be argued, extends well beyond the particular domain under examination.

Sweatshop labor has been condemned by scholars, activists, students and consumers in more developed countries on charges of wrongful exploitation, and a failure to respect the dignity, and basic needs of sweatshop workers. This paper surveys charges against sweatshop labor, and some of the more influential arguments for, and against, rectifying the background structural injustices that perpetuate it. I argue that in certain sweatshop cases, compensating workers below a prima facie morally acceptable level can be most successful in striving towards the duty of beneficence that employers owe to their employees. Therefore, we ought to pursue utility-maximizing acts over others in better alignment with a deontic duty to compensate employees at a certain level. I eventually conclude that this debate is a paradigm example of deontological versus utilitarian moral judgments. Sometimes, utility maximizing acts are morally impermissible. Sometimes, adhering to deontic duties instead of committing a wrong to produce a right is morally required. In the circumstances that I describe, the morally right acts ought to be those that are most successful in maximizing overall utility for the most number of people. This responsibility coincides with acts that may not compensate workers at a prima facie morally acceptable level, but incidentally maximize overall utility, welfare and autonomy for some of the world’s most marginalized and impoverished people.
