贪污、贿赂犯罪嫌疑人通常以拒供、谎供、翻供等方式来对抗对其罪行的侦查、讯问,侥幸、畏罪、矛盾、抗拒等心态是支撑上述诸种对抗方式产生的内在心理基础.犯罪心理学研究表明,检察人员在初查、第一次讯问等关键阶段对犯罪嫌疑人有意设定的心理限制,将带来对此类案件的突破. 相似文献

During the late 1970s, members of the Polish democratic opposition revised and reinterpreted key elements in the Polish past in support of their contemporary ideas about Polish society and opposition. The birth of the independent press in Poland in 1976 provided these debates with a medium for wide dissemination and discussion. Analysis of democratic opposition debates in the independent press on the Polish–Lithuanian Commonwealth, historic Polish–Russian relations, and the struggle for and achievement of independence in the early twentieth century shed light on the ways in which the democratic opposition perceived Polish society and the legacy of tolerance, diversity, nationalism, and socialism within it. It also reveals the major divisions within the democratic opposition and its primary tactical proposals prior to the birth of the Solidarity trade union in 1980. Forty years later, these debates continue to reverberate. 相似文献

This study examines the semiotic resources deployed in resisting negative stereotypes of Nigeria in the international community, particularly representations of the country in the Western media. Data for the study were drawn from Nigeria’s Heart of Africa nation branding campaign. The study applies the discourse-historical approach (DHA) pioneered by Ruth Wodak of the Vienna School of CDA. DHA attempts to integrate much available knowledge about the historical sources and the background of the social and political fields in which discursive events are embedded. Further applying Reisigl and Wodak's presentation of the discursive strategies normally oriented towards understanding texts related to nations and national identities, among others, the study reveals that in appropriating the semiotic resources in the campaign, the discourse producers have predilection for the discursive strategies of mitigating negative attributes which the out-group intensifies, and highlighting positive attributes which the out-group seemingly under-reports in its representations of Nigeria. Notwithstanding the rhetorical dynamics of the semiotic resources, the study concludes that enduring national image management thrives on creating new images and associations lived by a country’s citizens rather than tries to refute old ones. 相似文献

Global production network (GPN) analysts argue that workers actively contribute to the shaping of GPNs through different forms of agency. In this contribution I extend this argument to the tactical agency of small producers. By focusing on the phenomenon of side-selling among Filipino banana contract farmers, I show that these tactics have contributed to the emergence of alternative trade networks that undermined traditional lead firm behaviour and inspired new struggles over chain governance. However, as a diverse and ambiguous group of growers engages in this tactical agency, predominantly as small capital, they also contribute to the continuation of broader dynamics of capital accumulation and labour exploitation. 相似文献

ABSTRACTTeodor Shanin's The Awkward Class helped to launch two immensely important research directions. First, resistance by Russian peasants to modernizing agricultural policies by both Tsarist and Soviet governments opened new questions about collectivization of agriculture, and made Russian history relevant to the study of ‘developing societies.’ Second, the idea of cyclical mobility of peasant households challenged the then widely held assumption that peasants were destined to disappear. Instead of explaining ‘persistence’ of peasants, Shanin explored distinct logics of peasant households and communities. This helped to define a new inter-disciplinary field called peasant studies. 相似文献

This paper discusses the concept of memory as a form of humanist activism in the autobiographies of Nelson Mandela and Edward Said. Mandela and Said were chosen because they dedicated their lives to the cause of freedom in South Africa and Palestine. Their engagement with the political causes of their countries turned into a concern with worldwide struggles for human rights and racial equality. While Mandela emerged as a vital force against apartheid in South Africa, Said was a well-known and influential Palestinian critic and intellectual whose writings tackle the Palestinian struggle for justice within the worldwide experience of imperialism and its binary oppositions of white/black, male/female, superior/inferior. I argue that these autobiographies bear witness to the plight of Black South Africans and Palestinians as both a shared memory resistant to erasure and a call for justice. Mandela and Said used their personal memories and life stories to construct a public reading of the meanings of the events that shaped them. Here I focus on the concept of humanist and political activity in the two autobiographies. 相似文献
