This article has three interrelated objectives: firstly, it challenges monolithic depictions of the 2013 Gezi protests and conceptualizes the so-called ‘Spirit of Gezi’ as a highly influential—albeit temporary—power in the politics of Turkey. Secondly, it traces the success of the HDP (Peoples’ Democratic Party) in the 7 June 2015 parliamentary election back to Gezi while acknowledging the roots of the party within the Kurdish political movement. Thirdly, it examines the manifestation and subsequent decline of what is termed the human security moment in Turkey. The arguments of the work are mostly based on interviews with Gezi activists. It is argued that Gezi produced a discursive challenge to the national security-oriented understanding of the ‘Kurdish question’. Yet, even though the human security-oriented Gezi discourse had brought the Kurdish political movement and the Turkish left together, it ultimately failed to permanently transform Turkish politics due to the collapse of the peace process in June 2015. In addition to contributing to the literature on Gezi, the article also draws insights for security studies. It concludes that alternative discourses to the state-centric securitization approach to conflicts such as the Kurdish question can only have a lasting effect under conditions of ceasefire. 相似文献

Anti-M and anti-N monoclonal antibodies (MA) may be useful for bloodstain analysis by absorption-elution reaction. In order to detect N antigen in bloodstains aged up to 4 weeks the material tested must be treated by methanol. The material fixation is not recommended for analysis of "aged" bloodstains as well as for M antigen detection. Anti-M MA may be used for analysis of liquid blood using agglutination reaction. 相似文献

Data from 6 fertility surveys conducted in Mexico between 1969-87 were used to compare rural and urban fertility and to determine whether a significant level of contraceptive usage could be achieved in rural areas despite their lack of socioeconomic development. Age-specific marital fertility rates were calculated for the 4 national-level and 2 rural fertility surveys. The index of fertility control developed by Coale and Trussel was calculated for rural, urban, and all areas. The marital total fertility rate in rural areas declined from 10.6 in 1970 to 7.4 in 1982, a decline of 2.5% annually. From 1982-87 the annual rate of decline in rural fertility slowed to 1.6%, reaching 6.8 children in 1987. The urban marital total fertility rate declined from 7.72 in 1976 to 5.03 in 1987, while the marital total fertility rate for Mexico as a whole declined from 9.04 in 1976 to 5.85 in 1987. The indices of fertility control showed slowly increasing use of contraception in rural areas starting from the very low level of 1969. The urban index of fertility control showed some contraceptive use for all age groups in all surveys. The increases in contraceptive usage were considerable in rural areas from 1976-82 and much less marked in urban areas. From 1982-87 the inverse was observed and the fertility decline in urban areas was more marked. The condition of natural fertility found in rural areas in 1969 subsequently disappeared. Over time, fertility decline and use of contraception have intensified. Contraception is widely practiced in urban areas and is continuing to become more prevalent. The rural fertility decline in 1976-82 suggests that at least sometimes increases in fertility control are more important in rural areas than in urban areas. The theory of modernization, which holds that fertility decline in developed countries is attributable to factors associated with the process of modernization, thus comes into question. However, it is probable that a sustained fertility decline in the most depressed rural areas will be achieved only with substantial socioeconomic change. 相似文献
