根据丝光绿蝇在自然条件下的发育速度及其发育过程中的有效积温推断尸体的死亡时间。对在尸体腐败过程中最常见、国内分布极广的丝光绿蝇在自然条件下的发育速度及其发育过程中的有效积温进行观察、记录结果和统计学处理 ,分别确立了K1=2 0 880 + 0 80 14X1、K2 =5 4 0 917-2 8814X2 、K3=133 2 180 -2 6 312X3 等 3个有效积温与长度 (蛆 )和卵重的线性回归方程。应用丝光绿蝇发育速度与有效积温的回归方程 ,能比较准确地进行死亡时间的推断  相似文献

现行刑事自诉案件范围质疑与完善   总被引:1,自引:0,他引:1  
刑事自诉案件范围的“扩”与“限”体现着不同的诉讼理念 ,新刑事诉讼法对自诉案件范围作了较大扩张 ,从刑事起诉权发展规律考察却有违其发展趋势 ,立法规定也显得原则、简单 ,这种泛化的刑事自诉案件范围易引发一系列理论和司法实践问题 ,因此必须在借鉴国外相关立法的基础上对其进行反思和修改  相似文献

The employment of diverse forms of security and control on territorial borders have led to the production of numerous events of border crossings, smuggling, banditry and death along with stories of separation, loss, mourning, pain, and yearning in the everyday life of border people. The Naqshbandi Khaznavi order has an expansive interpersonal social network across the political borders of Turkish and Syrian nation-states. This work analyzes the ways in which Sufis dealt with diverse aspects of the Turkish-Syrian border by unbinding shackles and orders of political system that were fabricated constantly from the 1920s to the early 1980s. The life stories and narratives of the Sufis document the existence of a religious-cultural landscape, diversifying the perception of place, time and fear which have transcended political borders for decades, contradicting official cartographic imagination and the modern-secular understanding of place and time. Besides, in addition to analyses of religious orders as social, economic and political entities, this work aims to elucidate emotional aspects of relations and faith that coexist between Sufis and their Sheikh in the context of spatial distance, political border and fear of death.  相似文献

There is a long-standing debate about the nature, impact and significance of processes of differentiation in driving agricultural development. This contribution discusses three ways in which such processes have been conceptualized: modernization theories that put markets centre stage, Marxist theories that focus on class, and Chayanovian approaches that highlight the dynamics within farming families. The empirical evidence for testing these concepts is normally derived from agricultural censuses. This paper uses a different database that covers all Dutch farms between 1980 and 2006 and enables us to follow the changes on individual farms. Examination of this data reveals that the actual processes of differentiation that have occurred in this 25-year period differ greatly from the classic conceptualizations. It also challenges the conventional wisdom that agricultural development is mostly driven by larger farms.  相似文献

Adolescents spend only a fraction of their waking hours in school and what they do with the rest of their time varies dramatically. Despite this, research on out-of-school time has largely focused on structured programming. The authors analyzed data from the Educational Longitudinal Study of 2002 (ELS:2002) to examine the out-of-school time activity portfolios of 6,338 high school sophomores, accounting for time spent in school clubs and sports as well as 17 other activities. The analytical sample was balanced with respect to sex and racially and ethnically diverse: 49% female, 67% White, 10% Latino, 10% African American, and 6% Asian and Pacific Islander. Approximately 76% of the sample attended public schools, 30% were in the highest socioeconomic quartile, and 20% were in the lowest socioeconomic quartile. The authors identified five distinct out-of-school time activity portfolios based on a cluster analysis. The demographic profiles of students by portfolio type differed significantly with respect to sex, race/ethnicity, socioeconomic status, school type and location. Students by portfolio type also differed significantly in terms of measures of academic success, school behavior, victimization and perceptions of school climate, controlling for covariates. These findings underscore the importance of more complex considerations of adolescents’ out-of-school time.

How do economic sanctions affect presidential approval? Competing claims have been made about the domestic political consequences of economic sanctions. One claim is that sanctions are unpopular because they have negative economic consequences; another claim is that sanctions are popular because they project an image of strength; and another claim is that sanctions are neither popular nor unpopular because the public is uninformed about international affairs. These arguments imply competing identification restrictions. I test these competing models using a Bayesian Structural Vector Autoregression (B-SVAR) model. The results show that sanctions have a moderate negative effect on presidential approval. I use these findings as a basis for a broader set of auxiliary analyses. Despite received wisdom, sanctions imposed for different reasons against different target states do not produce disparate effects on public opinion. These analyses resolve an important empirical dilemma that weighs on a range of theoretical perspectives in the sanctions literature and highlights fruitful avenues for future research.  相似文献

This study highlights the role that critical events play in the demobilization of protest campaigns. Social movement scholars suggest that protest campaigns demobilize as a consequence of polarization within the campaign or the cooptation of the campaign leaders. I offer critical events as an alternative causal mechanism and argue that protest campaigns in ethnically divided societies are particularly combustible, as they have the potential to trigger unintended or unorchestrated communal violence. When such violence occurs, elite strategies change, mass support declines, and the campaign demobilizes. An empirical investigation of the dynamics of the demobilization phase of the anti-foreigner protest campaign in Assam, India, between 1979 and 1985 confirms this argument. A single group analysis is conducted to compare the dynamics of the campaign before and after the communal violence by using time series event data collected from The Indian Express, a national newspaper. The study has wider implications for the literature on collective action, as it illuminates the dynamic and complex nature of protest campaigns.  相似文献

中日两国新警任职教育比较研究   总被引:1,自引:0,他引:1  
在比较中日两国新警任职教育的定位、目标和内容等的基础上,提出了新警的任职教育过程应是一个"从不会到会"的过程;在教学内容基本相同的条件下,新警任职教育改革创新的着力点必然集中向教官、教法、教材(专用)和教具(设备设施)等方面;建议参考日本"新警返校复训制度";建议借鉴日本新警任职教育中每天"仪式"的做法,把现在的升国旗仪式与入警宣誓仪式合二为一,变成每天必行的一个"固定式"等个人观点。  相似文献

民生新闻的涵义是指从平民视角出发,关注平民百姓日常生活及其生存状态的新闻。民生新闻的意义在于开创了中国电视节目"本土化"的实践。安徽经视的《第一时间》、《帮女郎帮你忙》这两档节目,以服务群众为宗旨,走向基层贴近百姓,关注民生,加强与百姓互动,不断推出群众喜闻乐见的新闻,大力弘扬地域先进文化,折射出民众评判真善美与假恶丑的标准,是最具安徽本土化特色的电视节目。  相似文献
