Being a Contracting Party to the 1951 Convention Relating to the Status of Refugees and its Protocol with geographical limitation, Turkey provides conditional refugee status, not refugee status, to persons feeling persecution as a result of events occurring outside Europe. This study focuses on the rights of conditional refugees under Turkish laws and questions whether these rights comply with or diverge from the rights of refugee under the Convention. It draws conclusions on the significance and challenging character of the identified divergences and on the changes that Turkey needs to make in its laws in case of an eventual lifting. 相似文献

ABSTRACTThe current systematic literature review aimed to analyse the associations between temporary agency work (TAW), job satisfaction, and mental health in Europe, as well as to outline a future research agenda. Twenty-eight scientific articles were identified by searching different data bases (i.e. PSYNDEX, PsycINFO, PubMed, and Web of Science) for the time span from January 2000 to December 2016. Our review reveals first that TAW is not consistently negatively related to job satisfaction. However, job insecurity and working conditions are important mediators in the relation of TAW and lowered job satisfaction. Second, TAW is not consistently related to all investigated types of mental health impairments. However, when focusing on specific outcomes and comparing temporary agency workers to permanent employees, we still find consistent evidence regarding higher levels of depression and fatigue among temporary agency workers. Inconsistent associations between TAW, job satisfaction and mental health can partly be attributed to unfavourable methodological aspects of the included primary studies. To address these aspects, future research should consider applying a standard measurement of TAW, including a minimum of meaningful confounding variables, improving the operationalisation of outcome variables and the study design. 相似文献

In 1984, Gabow and Tarjan provided a very elegant and fast algorithm for the following problem: given a matroid defined on a red and blue colored ground set, determine a basis of minimum cost among those with k red elements, or decide that no such basis exists. In this paper, we investigate extensions of this problem from ordinary matroids to the more general notion of poset matroids which take precedence constraints on the ground set into account. We show that the problem on general poset matroids becomes -hard, already if the underlying partially ordered set (poset) consists of binary trees of height two. On the positive side, we present two algorithms: a pseudopolynomial one for integer polymatroids, i.e., the case where the poset consists of disjoint chains, and a polynomial algorithm for the problem to determine a minimum cost ideal of size l with k red elements, i.e., the uniform rank-l poset matroid, on series-parallel posets. 相似文献

The economic as well as political and ideological crises and transformations of capitalist social formations have created a crisis for Marxist approaches. This affects their assumption about the necessity, desirability and possibility of social transformation, but also about the actors fighting them out and their activities. Thus, a far reaching reformulation of its fundamental epistemological and theoretical assumptions is necessary. This contribution argues that the crisis of Marxism demands a self-reflective engagement with conditions of Marxist theoretical work. The acknowledgement of the fundamental openness and incompleteness of Marxist social critique as well as its contested production is indispensable to avoid authoritarian forms of politics and to be implicated into the legitimation of domination again. The encompassing character of the crisis tendencies of capitalist social formations and the multiplication of fields of conflict demands to overcome a monistic interpretation of social dynamics. To conceptualise capitalist social formations as relation of relations is an indispensable precondition for the analysis of the connections between different social structures and relations of power and dominance. Furthermore, the ability of capitalist social formations to change, which has been shown by the recent crises and transformations, demands a fundamental dynamisation of the Marxist concept of reproduction. The dynamisation of relative surplus production in knowledge based capitalism moves the adaptability of the subjects and their capacity to work centre stage. Only against this background can the plurality of perspectives for emancipation and social struggles come into view for Marxist theoretical work. 相似文献

Background: The prevalence rates for both sarcopenia and erectile dysfunction (ED) gradually increase in middle-aged and elderly diabetic male population and they impair physical functioning, sexual functioning, and quality of life. The aim of the present study was to evaluate the sarcopenia in patients with diabetic ED.Methods: The study included 98 male patients with type II diabetes mellitus (DM) aged 18–80?years. Blood chemistry and hormone levels were obtained. The International Index of Erectile Function (IIEF-5) questionnaire was administered to the patients. The patients were divided into three groups according to the IIEF-5 score; a score of 5–10 points indicated severe ED, a score of 11–20 indicated moderate ED, and a score of 21–25 points indicated no ED. The muscle mass, handgrip strength, timed up and go test, upper mid-arm circumference, calf circumference, and body mass index were obtained. The statistical analysis was performed using MedCalc Statistical Software version 12.7.7. All parameters were compared between the three groups.Results: Of 98 patients included in the study, 84 patients had severe sarcopenia, 13 had moderate sarcopenia, while only one patient had normal muscle mass. The mean age was 56.59?±?11.46?years. When patients were divided into three groups according to IIEF-5 score, 38 had severe ED, 39 had moderate ED, and 21 had no ED. There was a significant difference between the three groups in terms of handgrip strength, timed up and go test scores, upper mid-arm circumference, and calf circumference (p?.05 for all).Conclusions: Although muscle mass remains unchanged, muscle strength and physical performance decrease in diabetic ED patients. Diabetic patients with severe and moderate ED have lower muscle strength and physical performance. 相似文献

There are times when entire populations of certain countries have had to readjust their lives and economic strategies as all of society is under transition. Post-Soviet Central Asia underwent this period after 1991. During times of transition, there are always people that tend to be able to make use of the new uncertainties, even at the risk of entering legal grey areas. Here new social groups emerge, ethnic origin becomes relevant and new kinship ties are made. These transformation periods are often short and provide limited opportunities for analysing the strategies of those pioneers that I call Kairos economists. They often act only in cooperation with residents of the border and with duty customs and security personnel. This article analyses this special economy with the help of case studies that have been observed during the transformation period from the Soviet to an independent Central Asia. 相似文献
