Female subordination in the Arab-Israeli community: The adolescent perspective of “social veil” 总被引:1,自引:0,他引:1
Our research studied the gender-specific perceptions of Arab-Israeli adolescents regarding issues that determine female subordination (e.g., inheritance rights, freedom of movement, and female chastity). The main finding shows that young females oppose the imposition of social constraints upon women significantly more than their male counterparts, while both sexes are in agreement regarding the issues they conceive more or less traditionally; both express the strong conservative attitudes regarding the Islamic code of protecting female honor and chastity. The findings imply that, while females do not oppose the preservation of the cultural code that underlies their subordinate position, they ascribe to it more lenient normative implications.This paper developed out of the masters thesis of Mr. Mohammed Masalha submitted to the Department of Sociology at the Hebrew University of Jerusalem under the supervision of the first author and Professor Reuven Kahane. Special thanks are due to Helene Hogri for her indispensable editorial assistance and to Zvi Richter for his statistical aid. We also thank the NCJW Institute for Innovation in Education for funding the technical aspects of this paper. 相似文献

Some features of social living were investigated in three inbred strains of mice: C57Bl/6j, Balb/cj, and NIH. Five social behaviors--Aggression, Submission, Allogrooming, Social Rest and Rest Alone, as well as Wheel Running Activity--were recorded 2 h daily for a week, in 26 groups of seven male mice living in an enriched environment. Dominants and subordinates among strains shared some behavioral characteristics, but strain contributions upon social structure were also detected. Similarities among strains included the appearance of a single dominant mouse per group rated as the most aggressive, besides from being the animal presented with most Submissions. Allogrooming was more frequent among subordinates than among dominants and subordinates. Differences among strains were that agonistic behavior among subordinates was higher in the Balb/cj and NIH groups than in the C57Bl/6j mice. NIH mice were recorded in Rest Alone more often than mice from the other strains. C57Bl/6j dominants showed higher rates of Wheel Running Activity than subordinates. 相似文献

In some recent papers, the authors and Peter Gärdenfors have defined and studied two different kinds of formal operation, conceived as possible representations of the intuitive process of contracting a theory to eliminate a proposition. These are partial meet contraction (including as limiting cases full meet contraction and maxichoice contraction) and safe contraction. It is known, via the representation theorem for the former, that every safe contraction operation over a theory is a partial meet contraction over that theory. The purpose of the present paper is to study the relationship more finely, by seeking an explicit map between the component orderings involved in each of the two kinds of contraction. It is shown that at least in the finite case a suitable map exists, with the consequence that the relational, transitively relational, and antisymmetrically relational partial meet contraction functions form identifiable subclasses of the safe contraction functions, over any theory finite modulo logical equivalence. In the process of constructing the map, as the composition of four simple transformations, mediating notions of bottom and top contraction are introduced. The study of the infinite case remains open. 相似文献

People hold different perspectives about how they think the world is changing or should change. We examined five of these “worldviews” about change: Progress, Golden Age, Endless Cycle, Maintenance, and Balance. In Studies 1–4 (total N = 2733) we established reliable measures of each change worldview, and showed how these help explain when people will support or oppose social change in contexts spanning sustainability, technological innovations, and political elections. In mapping out these relationships we identify how the importance of different change worldviews varies across contexts, with Balance most critical for understanding support for sustainability, Progress/Golden Age important for understanding responses to innovations, and Golden Age uniquely important for preferring Trump/Republicans in the 2016 US election. These relationships were independent of prominent individual differences (e.g., values, political orientation for elections) or context-specific factors (e.g., self-reported innovativeness for responses to innovations). Study 5 (N = 2140) examined generalizability in 10 countries/regions spanning five continents, establishing that these worldviews exhibited metric invariance, but with country/region differences in how change worldviews were related to support for sustainability. These findings show that change worldviews can act as a general “lens” people use to help determine whether to support or oppose social change. 相似文献

The increasing use of digital technology-based retail services provides new opportunities for digital marketing. In this paper, we investigate how augmented reality (AR) technology can be leveraged as part of the firm's strategy. We explore the online purchase intention through AR smart glasses (ARSG), considering consumers' value assessment through a cost–benefit analysis and the influence of technical, experiential and social AR value drivers. We develop an augmented value-based adoption model addressing four main objectives: (1) Evaluate the effect of the perceived value of ARSG, (2) Evaluate the effect of immersion (experiential dimension), (3) Evaluate the effect of AR devices and technical complexity (technical dimension) and (4) Evaluate the importance of subjective norms (social dimension) on the online purchase intention through AR technology. Based on an ESIC Tech Lab experiment with two types of ARSG from market leaders and AR retail apps, the study uses survey data from 253 participants. The results suggest that the technical dimension has an ambiguous effect, with tech-complexity enhancing directly the perceived value of ARSG for online purchase while reducing the net value of consumers' economic cost–benefit analysis. We find strong evidence that the experiential and social AR dimensions (in the form of immersion and subjective norm) have a significant positive influence on consumers' purchase intention online, which are better predictors than the pure economic cost–benefit assessment (through usefulness and difficulty). Furthermore, the technical innovativeness of consumers is found to increase directly the online purchase intention through ARSG. 相似文献

The ability to empathize with others enables us to effectively interact with each other and may have specifically evolved to support parental roles and caregiving. The relationship between parenting and trait empathy is little understood as previous research focused on empathy exclusively in the context of parenting, for example parental sensitivity. Here we aimed to understand how trait empathy may moderate the association between child's negative emotionality and parental burnout. Two cohorts were examined (1) parents of infants (10–18 months old; N = 203) and (2) parents of children (3–10 years old, N = 201). Parents filled out a battery of online questionnaires assessing maternal empathy, parental burnout and child temperament. We found that the relationship between higher levels of negative emotionality and parental burnout is moderated by specific aspects of maternal emotional empathy. Our findings suggest that maternal emotional empathy acts as a buffer against parental burnout when faced with a child's characteristics that incur higher parental demands. 相似文献
