西藏问题长期以来成为中印两国关系健康发展的一个障碍。印度对西藏政策的从属性、两面性和长期性特点的形成,有来自深层次的国内因素,也有受复杂的国际背景的影响。近年来,印度政府开始意识到中印关系发展的重要性,并在西藏问题上采取了一些积极的措施。然而,双边关系的全面发展还将有待于两国在西藏问题上对现有分歧的超越。 相似文献

A review of recently developed simple techniques for analyzing data in the form of proportions from replicated, cross-sectional, sample surveys. (A) One variable over time—tests for homogeneity, pooling homogeneous proportions, tests for linear trends with as few as three time points, tests for departures from linearity; (B) Two variables with a constant percentage difference—four fold tables as rudimentary causal models, decomposing change with linear flow graphs; (C) Extension of the flow graph techniques to—three or more variables and changing coefficients; (D) Comments implying panel designs are somewhat over-rated and successive cross-sections somewhat under-rated. 相似文献

Areas of the world's three largest empires or states at any given time are listed at 100- or 50-year intervals, from 3000 b.c. on. Area measurement definitions and techniques are described. Major empire size has tended to increase, approaching the world's dry earth area in an approximately logistic way. This pattern suggests that a world state is still many centuries away. Sudden increases in empire size have occurred around 2800 b.c. due to emergence of cities, around 600 b.c. due to a power delegation breakthrough, and around 1600 a.d. due to a communication speed revolution. A graph of the world's largest empire areas throughout times offers somewhat novel perspectives on world history, making one realize the Western bias of many “world history” texts. Areas of 20 largest states that ever existed are listed. Subsequent papers will deal with historical periods in more detail. 相似文献

In an attempt to assess the national impact of anti-war protest, 15 major anti-Vietnam demonstrations occurring in the United States from 1965 through 1971 were analyzed for their effects upon Gallup public opinion survey data, American troop strength, and American munitions expenditures. While weak and short-term counterproductive effects appeared for two opinion indicators, an equally likely conclusion is that the demonstrations had little or no lasting impact whatsoever. The possible reasons for this finding, and its social implications, are discussed. 相似文献

农业保险的意愿和行为分别反映农户的潜在需求与有效需求,影响农户意愿与行为的因素或有不同,因此,农户意愿与行为可能存在差异。基于对玛纳斯、精河和沙湾三个棉花主产县棉农的问卷调查,对新疆棉农参与农业保险意愿和行为的差异及其影响因素进行了分析。结果表明,新疆棉农参与农业保险意愿低于实际参与率,影响其意愿与行为的因素既有共性又存在差异。同时,棉农对于能够同时覆盖自然风险及市场风险的农业保险产品存在潜在需求。研究认为,在推进棉花保险进程中,要重视棉农参保意愿对农业保险供给的影响,针对不同类型农户开发适销对路的农业保险产品。

Studies on youth leaving care have emphasized their limited social support and their need for continuing support after emancipation. However, less is known about the nature of their existing social networks after emancipation and their roles during their transition to adulthood compared with their noncare‐leaving peers. With this in mind, 32 young adults aged 18 to 25 participated in semi‐structured interviews regarding their current support figures in order to learn whether they were congruent with their needs after emancipation. Thematic analysis revealed four main features of the two groups' social networks: (a) stability versus uncertainty as to the lasting presence of the supportive figure, (b) reliance on parents as main supportive figures versus relying on different supportive figures, (c) confidence versus uncertainty in the supportive figures' ability to help, and (d) holistic versus fragmented support of the young adults' needs. The discussion addresses the unique characteristics of care leavers in emerging adulthood and the implications of their social networks' features for their adjustment after emancipation. One of the study's recommendations is to proactively connect them to new supportive figures such as professionals or mentors by offering them mentoring programs cognizant of the instrumental and developmental tasks of emerging adulthood. 相似文献

Most orphaned children in China are cared for by their extended families or become state wards under the guardianship of child welfare institutions. Some exceptions are children who are found and cared for by families in the community, without a formalized adoption or foster relationship. In some locations, institutions now accept guardianship for these children and support the informal adoptive family to continue to care for them. This article examines the outcomes for these children as they became young adults by comparing these 12 children raised within the system as they approach or have approached young adulthood (now aged 16–40 years-old). Some of the participants were either informally adopted or lived in institutional care. The results of this study found that the family environment was more conducive to the young people’s wellbeing as they approached or entered adulthood. The participants raised in informal care appeared to be treated similar to the biological children in these families. When the institution formalized the state guardianship responsibility, it also meant the families had state resources for support to protect the children’s rights to economic security, education, health care, and social participation. This practice by the institution supported the addition of informal adoption, as one step closer to permanency than foster care. Future implications include considering this option to help promote the family system assisting these children, families, and the state. 相似文献
