For over the past twenty years, the United States has witnessed a pro-patent movement. In response, numerous concerns have been raised, including possible impediments to innovation in cumulative technologies, emergence of anti-commons, barriers to entry and an elevation of costs of innovation associated with defensive patenting, growth in patent litigation and poor quality patents. Although there is little systematic evidence that these concerns have materialized in any substantial way, vigilance is nonetheless warranted.  相似文献

This study examined the relationship between social class and self-reported various juvenile delinquent acts in Ankara, the capital of Turkey. Data included 1,710 high school students using a two-stage stratified cluster sample. Such uncommon measures of social class as students' perceptions of their family economic status, the type of place where middle school was finished, home ownership, and car ownership were employed as well as often used measures of social class. The findings indicated that most of these new measures were not related to delinquency and that the class variables had low explanatory power. Various indicators of social class also presented contrary results. While some indicators of class showed that the relationship between class and delinquency was positive, other similar measures indicated the opposite.  相似文献

Migration has been a major source of human survival, adaptation, and economic change over centuries across regions. Today, more than ever, migration forms a central part of the global flow of humans, practices, and ideas. However, from a social point of view, migration is often considered as a potential source of social disorder and crime. Several explanations have been provided on this aspect in Indian context but none of these provide a sound analysis of the linkage between migration and crime. This paper attempts to investigate empirically the association between interstate migration and crime in India. Our analysis does not show any significant association between interstate migration and crime. Therefore, this study discards the controversial thought that migration is responsible for increasing crime in the nation, and suggests adopting constructive means to control crime rather than staring at migration.  相似文献

Studies on policy monitoring and ministerial survival within coalition governments are usually conducted separately. In this study, we bring these topics together and argue that the strategy of coalition partners to oversee the implementation of one another's policies has surprising consequences on the duration of office-holding ministers. Our main theoretical insight suggests that the degree to which ministers behave as faithful agents of the government depends on their expectations about their partners' monitoring behavior, such that when they expect to be under high scrutiny, they moderate their drifting behavior. Using evidence from legislative information requests on the activities of individual ministers over all multiparty cabinets formed in Brazil between 1995 and 2014, we demonstrate that: (1) greater policy monitoring by coalition partners is observed under more ideologically heterogeneous cabinets, and (2) more frequent policy-monitoring efforts by coalition partners lead to a lower ministerial replacement within the government term.  相似文献

Objectives

This paper tests the economic theory of criminal behavior. Specifically, it looks at “the carrot” side of the theory, studying how thieves react to changes in monetary gains from crime.

Methods

Using a unique crime-level dataset on metal theft in the Czech Republic, we study thieves’ behavior in a simple regression framework. We argue that variation in metal prices represents a quasi-experimental variation in gains from crime. It is because (1) people steal copper and other nonferrous metals only to sell them to scrapyard and (2) prices at scrapyards are set by the world market. This facilitates causal interpretation of our regression estimates.

Results

We find that a 1% increase (decrease) in the re-sale price causes metal thefts to increase (decrease) by 1–1.5%. We show that the relationship between prices and thefts is very robust. Moreover, we find that thieves’ responses to price shocks are rapid and consistent.

Conclusion

Our results are in line with the economic model of crime, wherein criminal behavior is modeled as a rational agent’s decision driven by the costs and benefits of undertaking criminal activities. Our estimates are also consistent with recent results from the United Kingdom, suggesting these patterns are more general.

This paper considers the relationship between the growing dominance of career politicians in the Australian federal legislature and models of party organisation. Using data on MPs in the Australian federal parliament, this study maps changes in models of party organisation to the occupational profiles of MPs between 1949 and 2007. The findings show a correspondence between the phenomenon of cartelisation and the appearance of legislators whose previous occupation was in the political sphere. The authors suggest that there is a relationship between different modes of party organisation and both the supply of candidates and the demand-side factors influencing party selectors. The paper concludes that theories of recruitment should include a greater emphasis on models of party organisation to explain better the uniformity of recruitment outcomes across advanced democracies.  相似文献

University R&D and Firm Productivity: Evidence from Italy   总被引:1,自引:0,他引:1  
Ed Mansfield wrote several papers on the private returns to basic research (e.g. Mansfield, 1980) and the influence of academic research on industrial innovation (e.g. Mansfield, 1991). We extend this line of research by assessing the impact of university research on total factor productivity growth of Italian manufacturing firms. The econometric analysis is based on reduced-form estimation of the R&D capital stock model, including controls for two potential sources of sample selection bias, as proposed by Crepon et?al (1998) and Piga and Vivarelli (2004). Our results suggest that while there are positive returns to collaborative research with other firms, collaborative research with universities does not appear to directly stimulate productivity. We interpret this result as consistent with recent evidence (e.g. Hall et?al 2001, 2003) suggesting that firms engage in collaborative research with universities when appropriability conditions are weak.  相似文献

The economic analysis of organised crime suggests that some economic activities are particularly vulnerable to penetration by criminal organisations. This paper provides an analysis of the structure of the Sicilian economy and shows that, when compared with other Italian regions, it is characterised by a disproportionate presence of such activities. In particular, the economy of Sicily appears characterised by: (i) a large dimension of traditional sectors, such as the Construction sector, which also has a strong territorial specificity; (ii) a large presence of small firms; (iii) a low level of technology; (iii) a large public sector. The joint presence of these features creates fertile soil for the typical activities of organised crime, such as extortion and cartel enforcement. Hence, we propose an alternative explanation of the persistence of organised crime with respect to explanations based on cultural and social factors.  相似文献

Research indicates that voters are not particularly effective at removing corrupt politicians from office, in part because voters make decisions on the basis of many competing factors. Party leaders are much more single-minded than voters and will choose to deselect implicated legislators if it means maintaining a positive party reputation and improving the odds of winning a legislative majority. We examine renominations to Italy’s legislature in two periods marked by corruption. We compare these renomination patterns with those from the prior legislature, when corruption lacked political salience. Our analysis shows that incumbent renominations are negatively associated with the number of press mentions that link the incumbent to corruption—but only when corruption is salient to the public. Our study highlights the importance of party leaders in forcing malfeasant legislators out of office—and reducing corruption—and redirects attention from voters to political elites as a critical channel in enforcing democratic accountability.  相似文献

Forensic practitioners and crime laboratories regularly collect and analyze fingernail evidence; however, the best techniques for processing such evidence have not been established. In this study, numerous aspects of fingernail evidence processing—collection of exogenous cells, transportation, purification of DNA, and STR analysis—were analyzed using fingernails harboring applied blood or epithelial cells from scratchings. Autosomal STR mixtures resulted when fingernails were soaked or swabbed, while scrapings rarely generated mixtures but exhibited allelic dropout. Y‐STRs yielded single source profiles, with scrapings again showing dropout. A silica‐based kit extraction recovered significantly more exogenous DNA than did organic extraction, neither of which was affected by nail polish. Swabbing nails in succession resulted in some cross‐contamination from exogenous material, while transporting nails together did not, although there was loss of exogenous cells. Optimized nail processing produced complete Y‐STR profiles of male volunteers from female fingernails following scratchings.  相似文献

创造性与道德的关系问题不仅是心理学中尚未解决的基本问题,而且是现代社会需要面对的现实难题。研究首次采用认知神经科学方法对创造性与道德的关系问题进行了实证研究,采用道德词汇分类任务将被试分为高道德组(高德组)和低道德组(低德组),并在控制智力、自尊以及记忆等干扰效应的基础上,借助脑事件相关电位技术记录了被试在解决顿悟字谜任务时的脑电活动。结果发现,高、低道德组被试在解决表征创造性思维的字谜任务时均表现出相似的脑电波形,但高德组被试较之低德组被试采用顿悟方式解决的字谜在200~360ms在额叶的广泛区域诱发了更低的脑电波幅。根据创造性的前额叶低激活理论,研究结果表明高道德组在解决创造性思维任务时表现出更高的创造性,也就是说,高道德意味着高创造性。  相似文献

The paper looks at the relationship between institutions and vote unity in national parliaments with the help of a large data set of votes from 33 national parliaments. The tests run are the first to confirm empirically the relationship between vote of confidence procedure and vote unity. The paper also provides a theoretical explanation for why the existence of the confidence procedure influences vote unity despite being used only rarely. The vote of confidence influences votes through the development of control mechanisms as well as the selection of party members who are more ideologically united. This study also challenges the view that electoral rules which make candidates individually accountable to voters necessarily lead to more vote defections. The findings suggest that higher personal accountability decreases vote unity only if party leaders do not control candidate nomination. Parties that rely on government finance for campaigns are also more united.  相似文献

This article investigates the determinants of criminal activityamong juveniles in the United States. It uses a survey of U.S.high school students conducted in 1995, which provides detailedinformation on offenses; personal, family, and neighborhoodcharacteristics; as well as deterrence measures. The determinantsof selling drugs and committing assault, robbery, burglary,and theft are analyzed separately for males and females. Theresults provide some evidence that juveniles respond to incentivesand sanctions. Employment opportunities and policies designedto increase the probability of arrest may be effective toolsfor reducing juvenile crime.  相似文献

This article argues that institutions not only reflect ideas prevalent at the time of their creation, but also play vital roles in driving the growth and dissemination of knowledge. Because institutions are not actors in their own right, however, it is essential to identify the mechanisms through which they influence the behavior of those who are producers and consumers of knowledge. The central section of the article explores three distinct mechanisms or families of mechanisms that come into play in this context:(1) framing the research agenda, (2) privileging certain types of knowledge claims, and (3) guiding the application of knowledge to specific policy concerns. The article's concluding section examines the policy implications flowing from the proposition that institutions play significant roles in creating knowledge regarding the issues they address. Throughout, observations relating to international environmental or resources regimes provide a source of illustrations.  相似文献

This paper focuses on interactive innovation. It starts by operationalising Regional Innovation in the context of multi-level governance. It shows how regional and external innovation interaction among firms and other innovation organizations is important for regional innovation potential. The ability to access and use funding for innovation support for regional firms and organizations is crucial for regional innovation promotion. Equity investment funding is more important than public funding, which tends to be cautious and otherwise risk avoiding, except in circumstances of market arrest or failure to develop. Regional systems of innovation are broader than single sectors or clusters but some of these will be strategically privileged recipients of policy support because of their growth performance or potential, rather than, as in the past, their uncompetitiveness. The paper devotes space to exploring biotechnology clustering from a regional innovation systems viewpoint, as an instance of rather strong sectoral, regional innovation systems capabilities, though integrated also to global knowledge supply and markets. Illustration is provided of the way such sectoral innovation systems work at local regional level by reference to cases from Cambridge, Massachusetts and Cambridge, England.  相似文献

This article develops two new tests of partisan and nonpartisan theories of lawmaking based on cutpoint estimates and measures of uncertainty about ideal point estimates. Theories of congressional organization make explicit predictions about the absence of cutpoints in certain intervals of the policy space. We test these theories with new cutpoint estimates and exploit the fact that the ideal points of members located far from the density of cutpoints are necessarily estimated with less precision. We validate our empirical approach through simulations, and we test three models of congressional organization using House roll call data from the 86th through the 110th Congresses (1959–2008). We find strong evidence of partisan agenda control. Our findings exhibit modest differences from the results predicted by Cox and McCubbins's party cartel theory: negative agenda control increases over time and is negatively correlated with the size of the blockout region.  相似文献

Recent research has demonstrated that individual crimes elevate the risk for subsequent crimes nearby, a phenomenon termed “near-repeats.” Yet these assessments only reveal global patterns of event interdependence, ignoring the possibility that individual events may be part of localized bursts of activity, or microcycles. In this study, we propose a method for identifying and analyzing criminal microcycles; groups of events that are proximate to each other in both space and time. We use the Global Terrorism Database (GTD) to analyze over 4,000 terrorist attacks attributed to the FMLN in El Salvador and the ETA in Spain; two terrorist organizations that were both extremely active and violent but differed greatly in terms of history, grievances and motives. Based on the definition developed, we find strong support for the conclusion that many of the terrorist attacks attributed to these two distinctive groups were part of violent microcycles and that the spatio-temporal attack patterns of these two groups exhibit substantial similarities. Our logistic regression analysis shows that for both ETA and the FMLN, compared to other tactics used by terrorists, bombings and non-lethal attacks are more likely to be part of microcycles and that compared to attacks which occur elsewhere, attacks aimed at national or provincial capitals or areas of specific strategic interest to the terrorist organization are more likely to be part of microcycles. Finally, for the FMLN only, compared to other attacks, those on military and government targets were more likely part of microcycles. We argue that these methods could be useful more generally for understanding the situational and temporal distribution of crime.  相似文献
