Chaya Brasz 《Jewish History》2001,15(2):149-168
The Dutch Jewish community is part of Western European Jewry and as such is part of what Bernard Wasserstein describes as the vanishing Diaspora. The community is one of Europe's smallest and it was also the Western European Jewish community most heavily damaged by the Shoah; it lost 75% of its population. It is surprising that the community still exists. It has gone through many changes, most notably in the 1960s. Progressive Judaism and the Lubavitcher Habad movement have made considerable inroads in the religious community, but the population has become largely secular, and new secular Jewish networks have been established. Dutch Jews have redefined their identity, shifting from “Dutchmen of the Israelite religion” to “Jews” or “people with a Jewish background,” belonging to a social and cultural minority. A small population exchange has taken place between Israel and the Netherlands. The brief baby boom after the Shoah and the newly formed networks outside the religious framework have revitalized the community. But most Jews in the Netherlands are married to non-Jews, and in spite of unique efforts to integrate the Israelis into the community, the future seems uncertain. This revised version was published online in June 2006 with corrections to the Cover Date.  相似文献

There have been several conscious efforts made by different stakeholders in the area of nanoscience and nanotechnology to increase the awareness of social and ethical issues (SEI) among its practitioners. But so far, little has been done at the laboratory level to integrate a SEI component into the laboratory orientation schedule of practitioners. Since the laboratory serves as the locus of activities of the scientific community, it is important to introduce SEI there to stimulate thinking and discussion of SEI among practitioners, which would eventually contribute toward the responsible development of this technology. In this article, through an example (at the Cornell NanoScale Science and Technology Facility (CNF), practitioners of which represent a section of the nano researchers’ community in the USA), it is shown how a SEI component can be incorporated into the laboratory orientation schedule of the practitioners from diverse disciplinary and institutional backgrounds. Results show that, at CNF, the practitioners enjoyed the discussion since most of them learned about SEI for the first time in their professional career. At the same time, some of them were also knowledgeable about SEI and contributed to the debates. Moreover, the SEI orientation had significant positive impact on the scientific community enabling them to self-reflect upon their own research and its implications for the wider society. This article also describes the efforts that were undertaken to disseminate this form of SEI orientation to other 13 USA universities within the National Nanotechnology Infrastructure Network (NNIN, one of the biggest networks funded from National Science Foundation for Nanotechnology research, of which CNF is a part). As a result of this effort, most of the NNIN sites have already started or were in the process of integrating a SEI component into their nanofabrication laboratories to make their users aware of SEI, ensuring eventual robust socio-technical integration in the NNIN laboratories. In the future, this form of SEI orientation can also be disseminated to other nanofabrication laboratories in the USA.  相似文献

This work aims to reveal some aspects of the scientific domain of Psychology, in the context of the internationally visible Spanish science in the databases of the Citation Index of The Institute for Scientific Information (ISI), which is represented by a map. We used the methodology of cocitation of thematic categories (JCR-Thompson Scientific), with which we obtained a representation of the scientific activity. The resulting map allowed us to focus on the area of Psychology, whose representation acts as database for the analysis of this discipline in the scientific field with international visibility. This study offers an empirical view of the underlying structure of Spanish Psychology. This is important because most scientists have an intuitive idea of this structure, but this may or may not be real. This way, we present a global vision of the entire discipline that favours its objective analysis as a function of scientists' behaviour as it affects their patterns of communication through the established formal channels.  相似文献

There is limited research into the realities of science blogging, how science bloggers themselves view their activity and what bloggers can achieve. The ‘badscience’ blogs analysed here show a number of interesting developments, with significant implications for understandings of science blogging and scientific cultures more broadly. A functioning and diverse online community (with offline elements) has been constructed, with a number of non-professional and anonymous members and with boundary work being used to establish a recognisable outgroup. The community has developed distinct norms alongside a type of distributed authority and has negotiated the authority, anonymity and varying status of many community members in some interesting and novel ways. Activist norms and initiatives have been actioned, with some prominent community campaigns and action. There are questions about what science blogging—both in the UK and internationally—may be able to achieve in future and about the fragility of the ‘badscience’ community. Some of the highly optimistic hopes which have been associated with science blogging have not been realised. Nonetheless, the small group of bloggers focused on here have produced significant achievements with limited resources, especially when one considers this in the context of community values as opposed to some of the expectations attached to science blogging within scientific cultures more broadly. While the impacts of this science blogging community remain uncertain, the novel and potentially significant practices analysed here do merit serious consideration.  相似文献

In this paper we discuss our conceptualisation of a 'health-enabling social environment', and some of the strategies we are currently using to build social contexts most likely to support effective HIV/AIDS management in southern Africa. In developing these ideas, we draw on our on-going collaboration with residents of Entabeni, a remote rural community in South Africa where 43% of pregnant women are HIV positive. The aim of this collaboration is to facilitate contextual changes that will enable more effective community-led HIV/AIDS management in an isolated area where people have little or no access to formal health or welfare support, and where HIV/AIDS is heavily stigmatised. We give an account of the three phases of collaboration to date. These include research; the dissemination of findings and community consultation about the way forward; preliminary project activities (skills training for volunteer health workers; partnership building and a youth rally) as a way of illustrating what we believe are six key strategies for facilitating the development of 'AIDS-competent' communities: building knowledge and basic skills; creating social spaces for dialogue and critical thinking; promoting a sense of local ownership of the problem and incentives for action; emphasising community strengths and resources; mobilising existing formal and informal local networks; and building partnerships between marginalized communities and more powerful outside actors and agencies, locally, nationally and internationally. We discuss some of the triumphs and trials of this work, concluding with a discussion of the need to set realistic goals when working at the community level in highly conservative patriarchal communities to tackle problems which may be shaped by economic and political processes over which local people have little control.  相似文献

The purpose of this article is to compare the theory and reality of agricultural research networks in sub-Saharan Africa. Networking is a mode of organization that generally suits the new environmental conditions. The analysis of the agricultural research network environment in sub-Saharan Africa shows that when institutional networks started to proliferate, human and institutional conditions were not yet ripe. This explained some of the problems. Nowadays, conditions have improved. Despite all difficulties, networks have contributed to creating a scientific community, have participated in apportioning and even harmonizing research activities, and have made it possible to maintain research activities in countries going through a crisis. Marie de Lattre-Gasquet is a researcher from the Centre de coopération internationale en recherche agronomique pour le développement (CIRAD), in France. Within the external relations directorate of CIRAD, she has been responsible for the relationships between CIRAD and international organizations. She has also actively participated in the preparation of CIRAD’s long-term strategy. She worked for the International Service for National Agricultural Research (ISNAR) in The Netherlands from 1983 to 1985. She holds a Master in International Management (AGSIM, Thunderbird Campus) and a Doctorate in Economy (Université de Paris X). He is mostly working on the agricultural research networks in sub-Saharan Africa. He holds a diploma from the Institut National d’Agronomie—Paris Grignon.  相似文献

Interventions aimed at enhancing mental health are increasingly centered around promoting community attachment and support. However, few have examined and tested the specific ecological factors that give rise to these key community processes. Drawing from insights from the ecological network perspective, we tested whether spatial and social overlap in routine activity settings (e.g., work, school, childcare) with fellow ethnic community members is associated with individuals’ attachment to their ethnic communities and access to social resources embedded in their communities. Data on routine activity locations drawn from the Refugee Well‐Being Project (based in a city in the Southwestern United States) were used to reconstruct the ecological networks of recently resettled refugee communities, which were two‐mode networks that comprise individuals and their routine activity locations. Results indicated that respondents’ community attachment and support increased with their ecological network extensity—which taps the extent to which respondents share routine activity locations with other community members. Our study highlights a key ecological process that potentially enhances individuals’ ethnic community attachment that extends beyond residential neighborhoods.  相似文献

Social network analysis has grown exponentially in recent years, giving rise to methodological innovations in different scientific disciplines. In psychology, social network analysis has been incorporated into studies of individual personality differences and has generated novel areas, such as network psychometrics and network interventions. In community psychology, a recent review examined the use of network analysis in American Journal of Community Psychology publications (Neal & Neal, American Journal of Community Psychology, 2017, 60, 279). Based on their study, the authors advise researchers to avoid using the fixed‐choice name generator when possible, as one of the five methodological recommendations proposed. In this essay, I explain how the recent increase of name generators with a fixed number of alters when studying personal networks is originally linked to an interest in describing structural properties. Second, I analyze the pragmatic contributions of this method: establishing a limit of alters a priori can entail advantages in terms of standardization and comparability of personal networks. Finally, to contextualize the methodological debate, I argue that personal networks represent the diversity of contexts in which the individual participates and are naturally integrated into community surveys.  相似文献

科学界关于“原型启发”催化创造发明中顿悟发生的事例十分普遍, 从中国的“鲁班从带齿边的茅草中得到启发而发明锯子”的传说, 到“瓦特从沸腾的开水壶上受到启发而发明蒸汽机”的经典故事, 都说明“原型启发”是创造发明的一种重要思维方式。然而, 由于创造发明思维过程的复杂性, 国内外关于创造性思维脑机制的研究还停留在非科学问题解决的研究上。依据科学家运用原型启发而成功发明创造的最新实例, 项目组编制了《创造发明实验问题材料库》, 并计划以功能性磁共振成像(fMRI)和事件相关电位(ERP)作为技术手段系统探讨原型启发催化创造发明中顿悟发生的脑机制, 例如, 原型激活和启发信息利用的脑机制、问题意识下灵感捕捉的脑机制以及原型知识表征、动机与情绪状态、大脑工作状态等因素对原型启发影响的脑机制。该研究的开展, 对理解人类的创造性本质具有重要的理论意义, 对培养和激发人的创造力具有一定的实践价值。  相似文献

As scientists and practitioners, behavior analysts must make frequent decisions that affect many lives. Scientific principles have been our guide as we work to promote effective action across a broad spectrum of cultural practices. Yet scientific principles alone may not be sufficient to guide our decision making in cases with potentially conflicting outcomes. In such cases, values function as guides to work through ethical conflicts. We will examine two ethical systems, radical behaviorism and functional contextualism, from which to consider the role of values in behavior analysis, and discuss potential concerns. Finally, we propose philosophical pragmatism, focusing on John Dewey's notions of community and dialogue, as a tradition that can help behavior analysts to integrate talk about values and scientific practices in ethical decision making.  相似文献

There is increasing use of functional imaging data to understand the macro-connectome of the human brain. Of particular interest is the structure and function of intrinsic networks (regions exhibiting temporally coherent activity both at rest and while a task is being performed), which account for a significant portion of the variance in functional MRI data. While networks are typically estimated based on the temporal similarity between regions (based on temporal correlation, clustering methods, or independent component analysis [ICA]), some recent work has suggested that these intrinsic networks can be extracted from the inter-subject covariation among highly distilled features, such as amplitude maps reflecting regions modulated by a task or even coordinates extracted from large meta analytic studies. In this paper our goal was to explicitly compare the networks obtained from a first-level ICA (ICA on the spatio-temporal functional magnetic resonance imaging (fMRI) data) to those from a second-level ICA (i.e., ICA on computed features rather than on the first-level fMRI data). Convergent results from simulations, task-fMRI data, and rest-fMRI data show that the second-level analysis is slightly noisier than the first-level analysis but yields strikingly similar patterns of intrinsic networks (spatial correlations as high as 0.85 for task data and 0.65 for rest data, well above the empirical null) and also preserves the relationship of these networks with other variables such as age (for example, default mode network regions tended to show decreased low frequency power for first-level analyses and decreased loading parameters for second-level analyses). In addition, the best-estimated second-level results are those which are the most strongly reflected in the input feature. In summary, the use of feature-based ICA appears to be a valid tool for extracting intrinsic networks. We believe it will become a useful and important approach in the study of the macro-connectome, particularly in the context of data fusion.  相似文献

Differences between academic and nonacademic psychologists may be viewed as immutable, worthy of encouragement, or as a situation which the latter group must remedy by becoming “more scientific.” We contend that for community psychology, which perceives theory, application, and action as valid aspects of its broad paradigm, it would be most adaptive toexplicitly address the challenge of managing a balance between diversity and cohesion. There are signs that the present leadership of Division 27 recognizes aspects of this problem and is reconsidering the role and purpose of the Division as an organizing framework for the discipline (Trickett, Note 3). It is our view that engendering a commitment from various subgroups within the membership to addressing the disparities revealed by our respondents is required for resolving what we see as major obstacles to future development of the discipline. The conceptual and empirical approach presented in this study can be an important tool in forging constructive solutions to the challenges we have presented.  相似文献

We believe that members of the scientific community have a primary obligation to promote integrity in research and that this obligation includes a duty to report observations that suggest misconduct to agencies that are empowered to examine and evaluate such evidence. Consonant with this responsibility, we became whistleblowers in the case of Herbert Needleman. His 1979 study (Needleman et al., 1979), on the effects of low-level lead exposure on children, is widely cited and highly influential in the formulation of public policy on lead. The opportunity we had to examine subject selection and data analyses from this study was prematurely halted by efforts to prevent disclosure of our observations. Nevertheless, what we saw left us with serious concerns. We hope that the events here summarized will contribute to revisions of process by which allegations of scientific misconduct are handled and that such revisions will result in less damage to scientists who speak out.  相似文献

公共物品困境中对惩罚的操纵表明:惩罚搭便车可以维持群体内的合作行为。早期研究表明, 惩罚的设置有助于建立社会合作规范, 有代价惩罚、利他惩罚和第三方惩罚等惩罚形式为间接互惠提供了合理的解释。随着实证研究的进一步深入, 惩罚表现出新的形式, 如自私惩罚和反社会惩罚, 被惩罚者的威胁报复将使合作者不再继续惩罚搭便车行为, 导致合作行为的减少直至消失。正当性理论、道德情感理论和文化基因协同进化理论表明惩罚的存在具有一定的必要性和价值, 惩罚的作用存在框架效应。本文介绍了一些有关的中介变量, 如利他、信任、声誉、文化、期望等, 可以对惩罚作用的积极面和破坏性予以适当的解释, 也为合作的心理机制研究提供新的视角。  相似文献

What is the significance of communication in science? Though the question has been addressed by researchers in a number of fields, most have tended to see communication as an intermediary step on the way to some other phenomenon of interest, aprocess that is only interesting insofar as it produces some other structural or functionalproduct, e.g., documents, organizations, or social groups. From a communication research perspective, however, the communication processes themselves are the object of study. The diversity and flexibility of scientists’ communication behavior, and the complexity of their communication channels, styles, messages and networks, have not been assessed as a set of related phenomena. Therefore, the purpose of this paper is to draw together several analytical concepts regarding scientific communication processes that have been proposed by the author elsewhere, including the issue of social representations (Lievrouw, 1990), the scientific communication cycle (Lievrouw and Carley, 1991), and the scholarly research narrative (Lievrouw, 1989, and Mokros and Lievrouw, 1991). The concepts are combined here into one conceptual framework and applied to the case of a single biomedical specialty, lipid metabolism research, which has developed from an esoteric biochemical subfield to a large and well-funded specializaiton with a great deal of influence on American culture’s preoccupation with heart disease.  相似文献
