We analyse the results of a survey conducted by the Bank of Italy in the spring of 2012 on Italian science and technology parks. First we describe the main features of science parks in Italy. Then we investigate whether they have been effective in improving the economic performance and innovative capacity of the firms located within them. We find a pronounced heterogeneity between science and technology parks, whose cooperation with public research institutions is characterized by physical proximity. Although the business situation of firms located in science and technology parks tends on average to be better than that of similar “non-park” firms, a difference-in-differences estimation shows that entering a science and technology park did not generally improve firms’ business performance and their propensity to innovate compared with external counterparts. 相似文献

The Application of Voltammetric Analysis of Δ9‐THC for the Reduction of False Positive Results in the Analysis of Suspected Marijuana Plant Matter 下载免费PDF全文
Marco A. Balbino Ph.D. Laura S. de Oliveira M.S. Izabel C. Eleotério Ph.D. Erica N. Oiye M.S. Maria F.M. Ribeiro M.S. Bruce R. McCord Ph.D. Antonio J. Ipolito M.S. Marcelo F. de Oliveira Ph.D. 《Journal of forensic sciences》2016,61(4):1067-1073
The development of methodologies using inexpensive, fast, and reliable instrumention is desirable in illicit drug analysis. The purpose of this study was based on cyclic voltammetry technique to differentiate the electrochemical behavior of ?9‐THC, the psychoactive substance in marijuana, and five different extract plants to yield false positive results after analysis protocol for cannabinoids using thin‐layer chromatography and Fast Blue B salt. After applying a deposition potential of ?0.5 V in a glassy carbon working electrode, the results indicated an anodic peak current at 0.0 V versus Ag/AgCl after addition of ?9‐THC solution in the electrochemical cell, and limits of detection and quantification were 1.0 ng mL?1 and 3.5 ng mL?1, respectively. Other interfering plants showed distinct amperometric responses. This methodology was useful to detect ?9‐THC even in the presence of the Fast Blue B salt, which avoided false positive results for all the studied extract plants. 相似文献

The Spitzenkandidaten experiment has elicited much interest in academic and political circles as a move towards further politicisation of important aspects of EU lawmaking. This article puts forward a sobering account of the normative and instrumental reasons that explain why these expectations were grounded on shaky premises and the experiment could not have delivered its promises. In particular, the article stresses (1) the failure in creating a channel for political opposition through the indirect election of the President of the Commission; (2) the adoption of a formal understanding of the institutions involved in the process, that is, a conception detached from their social basis and (3) the choice of the wrong institution for the purpose of politicisation. The article concludes with a modest proposal for the consolidation of the channels for political action already available at the level of the Member States. 相似文献

During the last decade, the phenomenon of citizen watches has become a common and meaningful element in citizen participation that aims to improve local public safety. This paper discusses citizen watches as a manifestation of the way citizens and state agencies are redefining and transforming their relationships. It examines the question of the extent to which citizen watches can be seen as examples of good citizenship. The Dutch government is currently appealing strongly for more citizen involvement in public matters, but is unclear about the kind of involvement it expects. The paper argues that citizen watches are mainly considered manifestations of ‘good citizenship’ by the government if they are set up in line with state objectives and are willing to serve as an auxiliary of the formal authorities in the neighborhood. Many citizen watches are therefore products of self-responsibilization processes, which have not yet received much academic attention. 相似文献

Governments led by technocrats remain a nebulous category in political science literature, with little clarity about how they differ from party governments, how many have existed and how we can differentiate between them. This article aims to provide that conceptual and empirical clarity. Having proposed an ideal type definition of ‘technocratic government’, it sets out three conditions for an operational definition of a ‘technocrat’ and, on that basis, lists the 24 technocrat‐led governments that have existed in 27 European Union (EU) democracies from the end of the Second World War until June 2013. It then classifies these according to their partisan/technocrat composition and remit. This allows for the presentation of a typology of four different types of technocrat‐led governments and the definition of ‘full technocratic governments’ as those which contain a majority of technocrats and – unlike caretaker governments – have the capacity to change the status quo. The article concludes that full technocratic governments remain extremely rare in EU democracies since there have been only six cases – of which three have occurred in the last decade. 相似文献

As a consequence of pharmaceutical advancements, HIV is no longer described in terms of the absence of health or presence of illness, and advertisements promoting anti-AIDS medications commercialize idealized and desirable bodies. The present study discusses representations of HIV/AIDS in commercial advertising and their change over time. The article traces the shift in AIDS/HIV representations in commercial advertising from the early 1990s, when images of decay and disease represented AIDS, to nowadays, when the wider availability of antiretroviral medications and their ability to prolong life produced new representations of HIV-afflicted bodies. Claiming that HIV individuals can lead a normal life where everything is possible, advertising has re-established the definition of a sick body. On the other hand, this marketing approach has important social implications because such representations minimize the seriousness of HIV infection and fail to take into account the real dangers of contracting HIV and to accurately represent the life with HIV and AIDS. 相似文献

The international literature shows that in 40–50% of the cases, homicides–suicides involving children under the age of 10 are committed by mothers. Here, we report some results on homicides–suicides, in the mother–child relationship, occurred in Italy between 1992 and 2010. We examined 36 cases of filicide–suicide mothers by consulting the archives of RAI, daily newspapers, and the ANSA news agency. We focused on: mothers and children's age, place of residence, date and place of the murder, number and sex of the murdered children, and modality of the homicide–suicide. At the time of the homicide–suicide, the average age of mothers was 35.4. The number of children killed by each mother was one, except in seven cases. All the women had underestimated psychopathological disorders and only six women were regularly treated. The dynamics and characteristics of the events were much more similar to suicides than homicides, so we can consider them as “extensive suicides.” 相似文献

Entrepreneurial performance of principal investigators and country culture: relations and influences
Manlio Del Giudice Melita Nicotra Marco Romano Carmela Elita Schillaci 《The Journal of Technology Transfer》2017,42(2):320-337
The paper focuses on the role of a country’s culture in influencing the entrepreneurial attitudes of Principal Investigators, in shaping their ability to combine knowledge theory and business practice, in determining their capacity to strengthen the cooperation between the two domains of research and business, and in supporting research spin-off creation in entrepreneurial universities. To make Principal Investigators’ orientation match Entrepreneurial Universities’ goals of the marketing of innovation and entrepreneurship is not an easy task. A research-oriented approach, rather than an explorative entrepreneurial orientation, is still predominant in Principal Investigators. Among the factors influencing the strategic orientation towards entrepreneurship of Principal Investigators, the paper argues that the country’s culture could be key. Evaluating the influence of the entrepreneurial culture on a Principal Investigator’s activity is critical in predicting his performance and comparing it with that of Principal Investigators in other countries. 相似文献

The article examines the role of national constitutional courts in supranational litigation. It firstly illustrates their value and situates well‐known judicial doctrines affecting their jurisdiction in the context of the normative claims, policy agenda and institutional framework promoted by the European Union. Against this background, it gauges the potential of national constitutional courts in countering the process of intergovernmental and technocratic encroachment of national constitutional democracies characterising the most recent evolutionary stages of the European integration process. It is claimed that constitutional courts are in the position of reinforcing, resisting or correcting Union measures with a detrimental impact on national constitutional principles. After having identified in correction the approach more coherent with their constitutional mandate, the article highlights a disturbing paradox: in remaining faithful to their constitutional role, constitutional courts contribute to the sustainability of a comprehensive institutional setting corroding the idea of constitutional democracy on which they are premised. 相似文献
