The act of contribution to the collective raises a major dilemma in contemporary religious Zionism in regard to girls and women: how to maintain their traditional restriction to the domestic sphere while allowing participation in national tasks that demand their presence in the male‐dominated public sphere. From in‐depth interviews conducted with 37 seventeen‐year‐old religious girls studying in a unisex residential boarding high school, we uncover the manner in which these girls, as they proceed to young adulthood, experience the act of contribution in three social arenas: the Bnei Akiva youth movement, national service and the domestic sphere. Our analysis reveals a gradual recruitment to contribution during the passage from girlhood to womanhood, paralleled by the gradual intensification of feminine’ qualities. This process facilitates the girls’ participation in the public sphere without challenging the traditional gender dichotomy. It also constitutes a central practice by means of which religious‐Zionist society recruits the girls to the Israeli collective yet keeps them within its own socio‐cultural boundaries. 相似文献

Complementary insights from Transaction Cost Economics (TCE) and the Resource-Based View (RBV) of the firm are combined to predict the relationship between firm specific technological knowledge and patterns of integration within organizational boundaries. The findings show that the level of Research and Development (R&D) intensity (representing the creation of firm specific technological knowledge) has an inverted U-shaped relationship with the propensity of firms to integrate activities within organizational boundaries. At low levels of R&D intensity, firms’ propensity to integrate their activities is low, but increases with escalating levels of R&D intensity in order to avoid the misappropriation of value generated by technological knowledge. However, beyond a certain R&D intensity level, the propensity to integrate activities declines, since the level of technological knowledge is high enough to prevent imitation by third parties. As expected we further find that firms which follow this integration pattern outperform those which do not. As the level of R&D intensity increases, the integration of production and marketing activities enables firms to improve performance until a certain R&D intensity threshold, after which such integration negatively affects performance. 相似文献

Utilizar un ordenador supone una simbiosis de nuestra inteligencia con una herramienta externa sin la cual la mente contaría sólo con sus propios medios y no funcionaría igual.Por otra parte, algunos de los procedimientos de uso del ordenador pasan de hecho a interiorizarse, a incorporarse autónomamente a la mente.Este artículo, que permite analizar ambos hechos, nos ayuda a tener claro el papel del ordenador en el aprendizaje y funcionamiento cognitivo 相似文献

Although interactive technology is presumed to increase student understanding in large classes, no previous research studies have empirically explored the effects of Clicker Cases on students?? performance. A Clicker Case is a story (e.g., a problem someone is facing) that uses clickers (student response systems) to engage students in understanding the meaning of the science contained within the story. Using an experimental randomized Solomon design across 11 institutions, we found that Clicker Cases increased student understanding more than PowerPoint lectures in large introductory biology classrooms, although there was variation across institutions and topics. By examining student performance in conjunction with faculty experience, we found that strong Clicker Cases created dissonance, captured attention and involved students in interpreting data or making decisions. This study provides a model for collaborative research across multiple institutions and demonstrates the need for using multiple institutions and topics in research on education. 相似文献

The approach of context collapse and the notion of unintentional context collisions are of importance to scholars of social media. Israeli public hospitals are a particularly suitable venue for studying these topics, as they employ both Jewish and Arab practitioners, who care for both Jewish and Arab patients amid an ongoing violent conflict. In-depth interviews were conducted with 50 managers and healthcare practitioners (physicians and nurses), both Jewish and Arab, employed at 11 public hospitals in Israel. We found that despite hospitals managements’ instructions to avoid political discourse, it erupts nonetheless whenever the conflict escalates. Fearing damage to professional relations and care of patients, political discourse spills over into social media, where political opinions are expressed mostly by Arab practitioners and stereotypical attitudes against Arabs are expressed mostly by Jewish ones. Our study exemplifies the usefulness of the context collapse approach—and specifically unintentional context collisions—to work organizations and all the more so to healthcare organizations. 相似文献

This paper explores the growing power of states in transnational regulatory policies for nanotechnology risks and thereby their impact on research and technology trajectories. Decentralization of governance structure has been reported by scholars, yet the role of the state is evolving and still underexplored. We draw on a case study of nanomaterials and chemicals policies, by analyzing recent regulatory developments in the EU and US. Using data-reporting and market-entry regulations as examples, the evidence demonstrates the expansion of state-centric market-oversight rulemaking, and ‘stronger’ patterns of centralization in the EU. We argue for a significant increase in regulatory power exertion, countering predominant views on decentralization as the prevailing governance response. These findings suggest the adaptation and strengthening of state-based regulatory systems in the context of scientific uncertainty and complexity of global nanotechnology settings; despite these challenges for policy making, the EU and the US are increasing government role in technology regulatory policy. 相似文献

People value those who act with others in mind even as they pursue their own goals. Across three studies (N = 566; 4- to 6-year-olds), we investigated children’s developing understanding of such considerate, socially-mindful actions. By age 6, both U.S. and Chinese children positively evaluate a character who takes a snack for herself in a way that leaves a snack choice for others over a character who leaves no choice (Study 1), but only when the actors had alternative possible actions (Study 2) and when a clear beneficiary was present (Study 3). These results suggest an emerging ability to infer underlying social intentions from self-oriented actions, providing insights into the role of social-cognitive capacities versus culture-specific norms in children’s moral evaluations. 相似文献

This study compared the acoustic properties of 26 (100% female, 100% monolingual) Danish caregivers' spontaneous speech addressed to their 11- to 24-month-old infants (infant-directed speech, IDS) and an adult experimenter (adult-directed speech, ADS). The data were collected between 2016 and 2018 in Aarhus, Denmark. Prosodic properties of Danish IDS conformed to cross-linguistic patterns, with a higher pitch, greater pitch variability, and slower articulation rate than ADS. However, an acoustic analysis of vocalic properties revealed that Danish IDS had a reduced or similar vowel space, higher within-vowel variability, raised formants, and lower degree of vowel discriminability compared to ADS. None of the measures, except articulation rate, showed age-related differences. These results push for future research to conduct theory-driven comparisons across languages with distinct phonological systems. 相似文献
