Objective . For the first time since the mid-1970s, this study explored sociodemographic correlates of abortion attitudes among Israeli Jews and compared them with those reported by the General Social Survey in the United States. Methods . A survey in the representative sample of Jewish adults living in urban areas across Israel ( N = 546) that included two related items on the attitude toward abortion for nonvital reasons. Results . Using multiple regression, four statistically and socially significant correlates of antiabortion attitudes were identified: Greater religiosity (especially Ultra-Orthodox affiliation), lower than average income, greater number of children, and right-wing political preference. Gender and age did not emerge as significant correlates of abortion attitudes. Whereas American Jews form the mainstay of the prochoice camp, Jews in Israel are clearly divided along the lines of religiosity, ethnicity, socioeconomic status, and political views. Conclusions . In both Israel and the United States, the sociodemographic profiles of abortion supporters and opponents have been rather similar and stable over the last 25 years. This may point to the stable patterns of religiosity in both societies, since antiabortion sentiments have mainly been fueled by religious fundamentalism, regardless of formal denomination.  相似文献

We investigate the small-sample properties of three alternative generalized method of moments (GMM) estimators of asset-pricing models. The estimators that we consider include ones in which the weighting matrix is iterated to convergence and ones in which the weighting matrix is changed with each choice of the parameters. Particular attention is devoted to assessing the performance of the asymptotic theory for making inferences based directly on the deterioration of GMM criterion functions.  相似文献

This paper links theory with practice. It discusses original video footage of Palestinians living in the Occupied Territories, filmed by an all-woman crew of Western film-makers and Palestinians, which aims to challenge mainstream Orientalist discourses. The footage was shot in and around Al Aroub refugee camp in the West Bank and distributed through a variety of exhibition platforms. Western representations of Arabs are normally framed in a manner that allows little sympathy and/or understanding of their plight. Research has also shown a lack of knowledge in the West about the Palestinian/Israeli conflict. Focusing on “ordinary and everyday” aspects of Palestinian life, rendered often “extraordinary” by the circumstances of occupation, the footage attempts to draw connections and similarities for a Western audience and to illustrate that Palestinian daily lives are not “played out” only in opposition to the Israeli regime. The paper explores methods of enabling access to Palestinian voices in their own terms, while eliciting the empathy of audiences more accustomed to dramatised and stereotyped images of Palestinian life in Western news and current affairs footage.  相似文献

Two assumptions which characterize the measurements of quality life (QOL) studies, are questioned by the present report: First, the assumption that QOL is the same thing for all subjects, is usually related to health problems and can easily be measured across subjects. Second, when this assumption is given up by introducing subjective base-rates in an intra-subject (before-after) design, researchers still tend to assume that no response shifts occur on the QOL scales, e.g., that these scales maintain the same meaning and values for subjects over time and interventions. In our study we found that QOL had different subjective interpretations [1--4]. While for some certain issues in their family-life determined their quality of life, for others these were issues at their workplace or of their health conditions. Second, when QOL was tested against a subjective base-line (for each individual according to their choices of domains), about eleven percent of the hypertensives and normotensives showed a clear response shift of scale-calibration over the period of one year. When the scores of these subjects were excluded, the significance of certain previously reported results changed. For example, the significant difference between normotensives and hypertensives concerning the change in their subjective evaluation of QOL over the year and their initial depression became more significant, while similar changes in their evaluation of sexual impairment and control at their work-place became insignificant. These results suggest that response shifts have to be traced and quantified, before one can claim any results (or lack of results) in 'before-after' designs, concerning subjective meaningful issues like quality of life.  相似文献

Understanding the experiences of street addicted people can help clarify the process of engaging people with this social problem. This study aims to discover the challenges of drug-dependent street people by exploring their lived experiences. This study was conducted using content analysis of qualitative interviews with 22 street recruited from within compulsory drug treatment centers in Tehran. Participants were selected through purposive sampling and their experiences of homelessness and addiction were collected through a semi-structured interview. After analyzing the data, three categories and eight sub-categories were determined. The main categories included instability, social distrust, and economic vulnerability. Instability includes experiences such as rejection from their home, street attraction, and avoiding returning home. The social distrust theme consists of experiencing the stigma related to addiction and high-risk behaviors. The economic vulnerability encompasses gradual capital loss and weakening their work status in the context of a weak economic foundation. Dependent drug use added to those isolating experiences leads to weakened family ties, and social and economic interactions and finally results in being disconnected completely from the community mainstream.  相似文献

Abstract

Firms operating in the automotive industry have traditionally been ascribed with efficiency and high levels of quality, as lean production has been extensively applied within this context, but given the recent dynamics in the automotive sector, there is also a need for high levels of flexibility, widening our attention to agile production. However, when lean and agile production have been explored simultaneously, the quality and flexibility trade-offs have been mixed and unclear. In order to dispel the lean-agile ambiguity, and given that both high levels of flexibility and quality are required within the automotive industry, the purpose of this study was to: (a) Identify the relationship between flexibility and quality; and (b) Explore the quality and flexibility differences between lean and agile production. Primary quantitative data was obtained via a survey and a total of 140 automotive manufacturing firms within the UK returned the survey. Logistic regressions were utilised as the main mode of analysis. Not only was an inverse relationship found between quality and flexibility, but our findings depict two distinctive Business Models (BMs) existing in the automotive industry, one lean and one agile. We advance the lean-agile debate by asserting that lean and agile firms acquire quality (efficiency) and flexibility strengths respectively, and not vice-versa. Given this, we theoretically side with the notion of performance ‘trade-offs’ and contend the idea that capabilities are cumulatively gained. By incorporating an argument built on the strategy literature on BMs and Dynamic Capabilities, we assert that lean and agile firms have evolved to underpin different kinds of competitive advantage within the same industry, but these advantages are placed at different tiers in the automotive supply chain.  相似文献

Despite broad progress in closing many dimensions of the gender gap around the globe, recent research has shown that traditional gender roles can still exert a large influence on female labor force participation, even in developed economies. This paper empirically analyzes the role of culture in determining the labor market engagement of women within the context of collective models of household decision making. In particular, we use the epidemiological approach to study the relationship between gender in language and labor market participation among married female immigrants to the U.S. We show that the presence of gender in language can act as a marker for culturally acquired gender roles and that these roles are important determinants of household labor allocations. Female immigrants who speak a language with sex-based grammatical rules exhibit lower labor force participation, hours worked, and weeks worked. Our strategy of isolating one component of culture reveals that roughly two thirds of this relationship can be explained by correlated cultural factors, including the role of bargaining power in the household, and the impact of ethnic enclaves and that at most one third is potentially explained by language having a causal impact.  相似文献

We consider the dynamic vehicle routing problem (dynamic VRP). In this problem, new customer demands are received along the day. Hence, they must be serviced at their locations by a set of vehicles in real time. The approach to address the problem is a hybrid method which manipulates the self-organizing map (SOM) neural network into a population based evolutionary algorithm. The method, called memetic SOM, illustrates how the concept of intermediate structure, also called elastic net or adaptive mesh concept, provided by the original SOM can naturally be applied into a dynamic setting. The experiments show that the heuristic outperforms the approaches that were applied to the Kilby et al. 22 problems with up to 385 customers. It performs better with respect to solution quality than the ant colony algorithm MACS-VRPTW, a genetic algorithm, and a multi-agent oriented approach, with a computation time used roughly 100 times lesser.  相似文献

This study was carried out among physically disabled street children (PDSC) in the city of Dhaka in Bangladesh. The aim of the study was to explore violence, negligence and suicidal tendency among PDSC. To do this, 30 PDSC (15 male and 15 female) were conveniently selected and interviewed with an interview protocol developed by a step‐by‐step process. The results of this study revealed that all the participants experienced physical violence but female children were more likely to experience sexual violence than male children. Violence against disabled children came from both family members or relatives and other people. As with violence, all the participants experienced some sort of negligence, again both from family members or relatives and other people. More importantly, this study found that more than half of the physically disabled children had suicidal tendency to some extent, i.e. some thought of committing suicide at least once in their life, while others attempted to commit suicide due to the sufferings that came with disability. This study concludes with some policy implications, particularly: providing counseling to parents and the disabled children; training of the service providers who provide services to disabled persons; and building awareness through mass media.  相似文献
