The purpose of this contribution is to examine the evolutionary transformations that have characterised the UK defence innovation
system since the mid 1980s. It focuses on the central and challenging issue faced by the Ministry of Defence (MoD) in implementing
effective governance mechanisms emerging from the continuous trade-off between short-term market driven measures motivated
by efficiency arguments, and more long term and relational considerations in terms of knowledge economics. Furthermore, in
terms of technology transfer, this evolution has been accompanied by a gradual shift from an initial logic of spin-off to society expected from government driven military projects, to a logic of spin-in where the main concern of the military sector is to broaden its industrial and R&D base.

Street-level interpretation and enforcement are critical to defining the meaning of law. To understand street-level regulatory decisions, prior studies have highlighted internal office conditions, neglecting the influence that peer offices can have. This study examines the role of horizontal inter-office interaction among frontline offices and illustrates how and under what conditions it shapes the meaning of law. Drawing on qualitative and quantitative data on Japan's Soil Contamination Countermeasures Act, this study reveals that inter-office interaction occurs within fixed groups and comes to shape shared interpretations of law that regulators believe are legally valid. This implies that under legal ambiguity, inter-office interactions develop institutionalized notions of appropriateness and reinforce the perception of legal consistency, which bolster the legitimacy of enforcement. Although peer office networks encourage convergence on the interpretation of law, because of their clustered structure, legal meanings develop differently across various groups. 相似文献

This study uses wholesale prices of MDMA for 59 cities in the USA published by the National Drug Intelligence Center (NDIC) over the period of 2002–2011 to identify trafficking patterns of MDMA. Price differentials and correlations between pairs of cities are used to infer the presence of a link and the direction of flow of MDMA. The presence of inward and outward links is used to categorise each city as a ‘source’, ‘destination’, ‘transit’, or ‘weakly integrated’ city. The analysis identified low prices close to the Canadian and Mexican borders, in a number of cities such as Chicago, Miami, New York City, a trio of cities in the Carolinas, and along the West Coast. A number of these cities are linked to large numbers of other cities, indicating hub- or source-like status. The findings generate insights into the status of major US cities in the MDMA trafficking network. 相似文献

The current paper aimed to investigate the effectiveness of five law enforcement interventions in disrupting and dismantling criminal networks. We tested three law enforcement interventions that targeted social capital in criminal networks (betweenness, degree and cut-set) and two interventions that targeted human capital (actors who possess money and those who possess precursor chemicals). These five interventions are compared with each other and with random (opportunistic) removal of actors in two settings: (i) with network adaptation incorporated into the simulations and (ii) without network adaptation. Results illustrate that the removal of actors based on betweenness centrality was the most efficient strategy, leading to network disruption in the least number of steps and was relatively consistent across replications. Targeting actors who possessed money was the second most effective overall and was also relatively consistent in its disruptive effect. 相似文献

Advances in technology have transformed fraud against consumers from face-to-face, victim-offender interactions to a crime that now transcends international boundaries. Although consumer protection issues have been of interest to investigative journalists and literary scholars for centuries, the topic has only recently been subject to serious criminological inquiry. Employing the American consumer protection movement as an historical framework, we examine the evolution of consumer fraud. Our review documents that progressive social and legal changes in consumer protection and corporate regulation, as well as developments in criminological research, correspond to prominent literary exposés of the time. In today's technological age, such a reactive response to consumer fraud is neither efficient nor effective. Contemporary criminologists need to simultaneously address the questions of ‘how’ fraud is perpetrated and ‘why’ it occurs. Toward this end, we identify methodological strategies and data sources to promote empirical and theoretical understanding of consumer fraud, and to ultimately contribute to multi-national crime control policy. 相似文献

In this article illegal immigrants, a relatively new group of immigrants living at the margins of society, are discussed. The question of the significance of crime for groups that are officially excluded from the formal labour market and public provisions, is presented within the framework of the Unknown City research project, conducted in the four largest Dutch cities (interviews with illegal immigrants; an ethnographic study to determine the extent of support by various ethnic communities; and an examination of the ways in which the restrictive policies towards illegal immigrants were implemented by the police, the Aliens Departments, and by professionals within public or semi-public institutions in the fields of education, healthcare and housing). Both the relatively limited involvement in crime in general and the differences between groups can be explained by the embeddedness of illegal immigrants in the labour sphere and the support by ethnic communities. Attention is paid to the social and legal construction of the illegal immigrant through new legislation and to the observation that illegality is increasingly linked to crime. The majority of illegal immigrants are not criminally active. One exception is the category that is active in the lower levels of the hard drug trade. The authors' analysis suggests that the perception of the criminal illegal immigrant first and foremost reflects the division between wanted and unwanted immigrants, which is the result of the shift towards a restrictive policy. 相似文献

在网络信息系统安全管理中,使用签名Applet访问客户端资源能更灵活地扩展网络应用。然而在现行的Applet签名方案中,由于Jar包使用常规的签名方法,使客户端仅允许指定安全服务器中的Applet签名程序访问本机资源,而其他服务器的Applet程序即使被证明是可信的也无法实现同样的功能。这样的设置尽管保证了客户端访问的安全性,却使得网络分布性资源使用的效率无法提高,限制了网络应用。针对于此,该文提出了用椭圆曲线实现的Applet代理签名新方案,并对该方案的安全性进行了分析。 相似文献

The social sciences have mostly focused on the formation of social opinions from a semantic point of view: given a certain semantic field, interviews, statistics, and other analytical instruments are commonly deployed in order to map the distribution of views, their evolution, their conflicts and their agreements. Socio-semiotics, social semiotics, and the other semiotic branches that bear on social inquiry have contributed to the effort by providing semiotic grids of categorization. These grids too, however, have been mostly related to semantic contents circulating through societies and their cultures. The present article pursues a different hypothesis. After briefly recalling the events of 7–9 January 2015 in the Parisian area, the article seeks to survey and map the syntax of progressive differentiation of opinions circulating in the social networks about such events. Some patterns are identified and semiotically described: (1) cleavage; (2) comparative relativizing; (3) blurring sarcasm; (4) anonymity; (5) unfocused responsibility; (6) conspiracy thought. A new semiotic square is created to visually display these patterns, their positions, their relations, and their evolution. 相似文献

This study capitalizes on a natural experiment in Montgomery County, Maryland, where low-income applicant families are randomly assigned to public housing that is either (a) clustered within seven public housing developments or (b) scattered into market-rate subdivisions via the county's inclusionary zoning policy. Through a survey of 453 public housing residents, we find that adults who lived in scattered public housing reported a lower proportion of low-socioeconomic status (SES) social ties generally and a lower proportion of low-SES neighbors specifically in their social networks. They also counted more high-SES individuals in their social networks, and this effect was related to the amount of time they lived in the neighborhood. Living in scattered public housing had no adverse effect on feelings of neighborhood belonging or satisfaction. The socioeconomic composition of respondents' social networks was associated with two health outcomes for respondents (smoking and depression) and modestly associated with respondents' household income. 相似文献
