Organized crime is often perceived in terms of extended, hierarchical crime “families” that extend not only their activities but also their authority structures across national boundaries. However accurate such a view may or may not have been in the United States, where it originated, evidence from a Dutch survey of organized crime enterprises reveals a different picture. For organized crime in northwestern Europe, it is more helpful to think of crime markets of two kinds: those in which the goods and services are themselves forbidden, and those in which legal goods and services are handled in illegal ways. Case studies of the drug trade, and of organized crime in the business realm, offer a detailed look at these two kinds of markets. The evidence suggests that while organized crime enterprises conduct trade across national boundaries, they do not constitute an international authority structure. Crime entrepreneurs constitute a challenge, not to the basic structure of society itself, but rather a more subtle kind of challenge to basic values and morals, particularly when criminal enterprise is linked to power at higher levels of society.  相似文献

The structure and organization of the middle tier of higher education in similar institutions in the U. K. and U. S. are compared to draw conclusions on the effect which differences and similarities have upon the quality of the educational process, its cost-effectiveness, student independence and maturity, faculty load, relationships with business, industry and government.  相似文献

Patterns of suicidal behavior vary among cultures and along gender. Young Hindustani immigrant women attempt suicide four times more often than young Dutch women. This article explores multi-disciplinary explanations for suicidal behavior in this group. The interconnection of Durkheimian concepts of social integration and regulation with ecological insights into family relations and psychological and psychiatric theories on individual distress are relevant. It is suggested that young Hindustani women who display suicidal behavior possess certain personality and cognitive constellations that are interlocked with specific parenting styles in stressful family environments. These families are embedded in a context of moral transformations resulting from migration to a Western culture and may be facing difficulties accompanying the transitional processes encountered in the West, particularly those regarding gender roles. Durkheimian fatalistic and anomic suicides elucidate this. The Hindustani women who appear most at risk are those facing contradictory norms and overregulation, which prevent them from developing autonomy.  相似文献

This paper focuses on the psychology of social change and social justice. Specifically, we focus on subordinates’ reactions to new and old supervisors, and we argue that in evaluating these different types of supervisors, subordinates may rely on prior fair or unfair experiences as temporal frames of reference. We further propose that a result of these frames of reference may be that previous fairness experiences have a bigger impact on subordinates’ reactions to subsequent neutral communications when an old rather than when a new supervisor is the source of that communication. Findings of two empirical studies indeed show that subordinates who had had fair experiences with a particular supervisor reacted more positively toward subsequent neutral messages when the communication was coming from the old supervisor rather than from the new supervisor. Subordinates who had had unfair experiences, however, reacted more negatively toward the communication when the source was the old rather than the new supervisor. Some evidence was also found for contrast effects such that people who react to a new supervisor may react more positively with the neutral demand from this authority figure when they have earlier experienced unfair as opposed to fair treatment by a different supervisory agent. These findings were obtained on subordinates’ satisfaction with the supervisors’ communication and their acceptance of the supervisor. Finally, we discuss the implications for the psychology of social change and social justice.  相似文献

This study investigates media priming effects in the context of a Summit meeting of European Union (EU) leaders. It differs in four ways from most previous non-experimental priming studies: (1) it provides survey data accompanied by a content analysis of the news, (2) it compares priming effects on evaluations of a number of political leaders, who differed in their visibility in the news, (3) it involves an issue with low salience, and (4) it studies priming effects in the context of a European Parliamentary democracy. The study involves a two-wave panel study (before and after the Summit) on a representative sample of 817 Dutch adults, and a content analysis of the newspaper and television news in the 8 weeks leading up to the Summit meeting. The study shows that media priming effects occur only for the politicians who appeared visible in the news in connection with the issue. The media priming effects were not significantly moderated by political attentiveness or by political knowledge. We also explore the aggregate level consequences of priming for the popularity of leaders, and demonstrate that, as a result of media priming, two politicians became more popular, despite having received a bad press.

This study examines the network structure of policy learning in the C40 Cities Climate Leadership Group, which is a network of the world??s largest cities committed to tackling climate change issues. Among forty members and nineteen affiliate members, we ask the question with whom do cities learn and why? How are policy-learning relationships associated with cities?? multi-stakeholder governing body, policy performance, and cultural similarities? While studies on learning have analyzed conditions facilitating learning, quantitative studies of local government learning in global networks are rare. To facilitate the investigation into learning, we conceptualize learning as a process comprising information seeking, adoption and policy change, and focus on information seeking as the foundation step in the learning process. This social network analysis using the exponential random graph model reveals the cities that seek information and those that are information sources are different subgroups. Furthermore, analysis of nodal attributes suggests that transmunicipal learning in the C40 network is facilitated by the presence of a multi-stakeholder governing body; homophily of culture (language and regional proximity); and higher level of climate change policy performance. Creating a multi-stakeholder governing body could ensure participatory representativeness from citizens and relevant stakeholders to enhance climate change policy engagement and decision making as well as policy learning.  相似文献

Each digital camera has an intrinsic fingerprint that is unique to each camera. This device fingerprint can be extracted from an image and can be compared with a reference device fingerprint to determine the device origin. The complexity of the filters proposed to accomplish this is increasing. In this note, we use a relatively simple algorithm to extract the sensor noise from images. It has the advantages of being easy to implement and parallelize, and working faster than the wavelet filter that is common for this application. In addition, we compare the performance with a simple median filter and assess whether a previously proposed fingerprint enhancement technique improves results. Experiments are performed on approximately 7500 images originating from 69 cameras, and the results are compared with this often used wavelet filter. Despite the simplicity of the proposed method, the performance exceeds the common wavelet filter and reduces the time needed for the extraction.  相似文献
