This article demonstrates how the gendered patriarchal mechanisms that exclude women from the political sphere are being produced, re-produced, and challenged in interpersonal political conversations by concentrating on the discursive mechanisms that construct the way young Israeli women and men talk about politics. The research is based on a yearlong intra-group dialog process. The group met for weekly sessions during two semesters, in which the group members discussed and expressed their thoughts and feelings regarding the Israeli–Palestinian conflict. Critical discourse analysis (CDA) demonstrated how the political space is being marked, defined and delimited through gendered discursive practices. We present the different roles participants take in the group, and in particular the different strategies women use in face of disciplinary discursive mechanisms. The process revealed that the development in the group discussion was strongly intertwined with the change in the positioning strategies of the female participants. In particular, we found that women deployed emotionality as a tool of resistance that challenges gender binaries and masculine dominance. Our conclusion highlights the importance of the daily interactions in creating, sustaining and changing the political discourse of a society in conflict.  相似文献

Two effects of occupational structure on nuptiality levels are examined: a direct functional effect related to the influence of socioeconomic characteristics on the feasibility and desirability of marriage, and an indirect structural effect related to nuptiality levels via sex selective migration patterns and population sex ratios. Our analysis shows that nuptiality levels in nineteenth century English and Welsh districts were responsive to occupational variation and that both direct and indirect effects were significant. Our results suggest that socioeconomic factors, often overlooked in favor of cultural explanation, must be considered in the analysis of nuptiality.  相似文献

Nocturnal flying insects were collected monthly for 13 months using ultra violet light-traps set at various vertical levels in a weakly-seasonal, tropical lowland dipterocarp forest in Sarawak, Malaysia. Abundance, faunal composition, size distribution and guild structure of these samples were analyzed with respect to temperal and vertical distributions. The nocturnal flying insect community in the canopy level was highly dominated by fig wasps (84%) in individual number, and by scarabaeid beetles (28%) in weight. A principal component analysis on monthly catches detected non-random, seasonal trends of insect abundance. The first two principal trends were an alternation of wetter (September to January) and less wet seasons (February to August) and an alternation between the least wet (January to March) and the other seasons. Many insect groups were less abundant in the least wet season than the other seasons, whilst inverse patterns were found in Scarabaeidae and Tenebrionidae. Significantly positive and negative correlations between monthly catch and rainfall were detected only in ovule-feeders and in phloem-feeders, respectively. Delayed, significant negative correlations between monthly catch and 1–3 month preceding rainfall were more frequently detected in phytophages, phloem-feeders, seed-feeders, wood-borers and scavengers. The peak in abundance along vertical levels were found at the canopy level (35 m) for phloem-, ovule-, seed-, root-, fungal-feeders and nectar collectors, at an upper subcanopy level (25 m) for scavengers and aquatic predators, and at a middle subcanopy level (17 m) for ants. Catches at the emergent level (45 m) did not exceed those at the canopy level.  相似文献

This paper examines the determinants of the adoption of the veterans' pension program and how it served as a prototype for the creation and administration of the federal welfare system in the United States. We provide statistical evidence in the form of an analysis of votes in the House of Representatives that state-based special interests which had supported the ongoing liberalization of the veterans' pension program provided significant support for the adoption of the Social Security Act of 1935. There is clear evidence the social security system was not adopted as a simple extension of state old-age pension programs.  相似文献

The authors propose a new class of robust estimators for the parameters of a regression model in which the distribution of the error terms belongs to a class of exponential families including the log‐gamma distribution. These estimates, which are a natural extension of the MM‐estimates for ordinary regression, may combine simultaneously high asymptotic efficiency and a high breakdown point. The authors prove the consistency and derive the asymptotic normal distribution of these estimates. A Monte Carlo study allows them to assess the efficiency and robustness of these estimates for finite samples.  相似文献

关于党与人大在国家中地位的理性分析   总被引:1,自引:0,他引:1  
党政关系是政治体制改革的中心环节,党政关系之所以难分难解的根本原因之一就在于党部分地承担起本应由人大来履行的职责,所以说党政关系最重要的就是党与人大的关系。只有正确处理党与人大的关系才能从根本上克服“党政不分”的弊端。然而,正确处理党与人大的关系却是一个复杂且难度很大的问题。对党与人大在国家中地位的分析可以帮助我们更好地处理两者的关系。  相似文献

The Cross-Cultural Adaption Model (XCAM) is designed to help identify cultural values contained in the text, narration, or visual components of a learning instrument and enables the adapter to evaluate his adapted model so that he can modify or revise it, and allows him to assess the modified version by actually measuring the amount of cultural conflict still present in it. Such a model would permit world-wide adaption of learning materials in population regulation. A random sample of the target group is selected. The adapter develops a measurin g instrument, the cross-cultural adaption scale (XCA), a number of statements about the cultural affinity of the object evaluated. The pretest portion of the sample tests the clarity and understandability of the rating scale to be used for evaluating the instructional materials; the pilot group analyzes the original version of the instructional mater ials, determines the criteria for change, and analyzes the adapted version in terms of these criteria; the control group is administered the original version of the learning materials; and the experimental group is administered the adapted version. Finally, the responses obtained from the XRA rating scale and discussions of both the experimental and control groups are studied and group differences are ev aluated according to cultural conflicts met with each version. With this data, the preferred combination of elements is constructed.  相似文献

Rumors are among the serious problems of the National Population Program today. The principles related to the origin of rumors, who starts rumors pertaining to family planning, and how they spread are outlined. The basic approach in countering rumors for the pill and IUD is diagrammed so that each potential rumor is countered by a medical or nonmedical/technical explanation. Strategies used by information-education-communication programs to prevent rumors such as the small group discussion, selection and training of motivators, and use of mass media are discussed. Rumors about family planning are counteracted not with the use of elaborate techniques but with clear and fairly simple reassurances supported by medical evidence and case histories.  相似文献

Risk analysis is challenged in three ways by uncertainty. Our understanding of the world and its uncertainties is evolving; indeterminism is an inherent part of the open universe in which we live; and learning from experience involves untestable assumptions. We discuss several concepts of robustness as tools for responding to these epistemological challenges. The use of models is justified, even though they are known to err. A concept of robustness is illustrated in choosing between a conventional technology and an innovative, promising, but more uncertain technology. We explain that nonprobabilistic robust decisions are sometimes good probabilistic bets. Info‐gap and worst‐case concepts of robustness are compared. Finally, we examine the exploitation of favorable but uncertain opportunities and its relation to robust decision making.  相似文献

In this paper we analyse the impact of mothers’ employment status and formal child care attendance during early childhood on children’s school grades later in life, controlling for socio-demographic factors. We use the year 2008 of the Italian ISFOL-PLUS dataset. The dataset provides information on each respondent’s demographic characteristics, as well as a set of retrospective information on the individual’s school grades at the end of junior high school, high school, and university, along with (in the 2008 wave only) information about the respondent’s formal child care attendance and mother’s employment status when he or she was under age of three. We estimate the effects of maternal employment and child care attendance on the probability that the respondent would have high grades at the end of high school. Since maternal employment and child care attendance are likely to be endogenously determined, we use an instrumental variable approach. Our empirical results show that while having a mother who was working (during early childhood) had no significant effect on an individual’s high school grades, child care attendance had a positive and significant effect. These results have potential policy implications. As maternal employment does not seem to negatively affect the development process of children, while child care attendance appears to have a positive impact on academic achievement, policy makers should consider expanding the availability of child care and promoting women’s participation in the labour market.  相似文献
