Drawing on institutional theory, this article articulates qualitative insights from a program of research on Canadian health technology‐based ventures to examine the rules that characterize economic policy, capital investment, and regulatory approval as well as the way these institutions enable and constrain the development of ventures at an early stage. Our findings clarify how economic policy integrates these ventures into the entrepreneurial domain, how capital investment configures them for economic value extraction, and how regulatory approval fully releases their market value. These findings help to revisit current policy modernization initiatives by calling attention to the convergence among the three institutions. Rather than operating solely as a source of constraints, these institutions provide a highly integrated market‐oriented space for health technology‐based entrepreneurial activities to unfold.  相似文献

This paper presents the results and policy implications of a study that examined the spawning of founders who had previously been employed at large corporations. We found that spawning of founders is positively associated with the parent companies' productivity, innovativeness, and headquarter location. Furthermore, we found that the spin‐off per employee rate is higher in smaller establishments. We also found that the local entrepreneurial culture is significant in explaining local spawning of founders. Finally, we present new empirical evidence on the crucial role of successful homegrown companies in regional cluster development. More specifically, we found that the existence of successful homegrown companies is significantly correlated with the level of the regional entrepreneurial activity. This finding is consistent with the finding of many cluster development case studies. Thus, we argue that successful homegrown companies have a unique role in cluster development. This role can seldom be replaced by nonhomegrown companies. This is related to the notion that prior to the development of an entrepreneurial cluster, some intangible precondition should be realized such as the appearance of local role models and a shift toward a more entrepreneurial culture. In a more general perspective, these results support the notion that knowledge‐based regional development is a complex process that requires a long‐term and continuously adjusting supporting policy rather than being based mainly on attracting established companies' R&D centers to the region.  相似文献

Several types of biological samples, including hair strands, are found at crime scenes. Apart from the identification of the value and the contributor of the probative evidence, it is important to prove that the time of shedding of hair belonging to a suspect or victim matches the crime window. To this end, to estimate the ex vivo aging of hair, we evaluated time‐dependent changes in melanin‐derived free radicals in blond, brown, and black hairs by using electron paramagnetic resonance spectroscopy (EPR). Hair strands aged under controlled conditions (humidity 40%, temperature 20–22°C, indirect light, with 12/12 hour of light/darkness cycles) showed a time‐dependent decay of melanin‐derived radicals. The half‐life of eumelanin‐derived radicals in hair under our experimental settings was estimated at 22 ± 2 days whereas that of pheomelanin was about 2 days suggesting better stabilization of unpaired electrons by eumelanin. Taken together, this study provides a reference for future forensic studies on determination of degradation of shed hair in a crime scene by following eumelanin radicals by utilizing the non‐invasive, non‐destructive, and highly specific EPR technique.  相似文献

This paper provides a critique of attempts in the field of political communication to explain apparent voter apathy and declining electoral turnout. The response of many commentators is either to blame the media for the problem or to see the media as the solution to any problem that might exist. First, the paper examines the ‘blame the media’ school of thought—as exemplified by liberal commentators in the UK and the USA. Secondly, the paper focuses on the ‘optimists’ who argue that the spin/media nexus is either morally neutral or may actually be improving citizen involvement. The paper argues that both approaches are flawed at the level of conceptualisation and of methodology. The narrow conceptualisation of the field means that even in the unusual cases where scholars look beyond the question of elections, the research agenda is still fixed at the level of media power and not on how the media fit into a wider system of power relations. Most obviously, the field tends to avoid the question of political and economic outcomes. The paper ends by suggesting that the problem of disengagement from formal politics is a response to the crisis of legitimacy in the institutions of democracy in the USA and UK.

Abstract

The purpose of this qualitative research was to examine the change process experienced by imprisoned sex offenders during incarceration from the standpoint of emerging positive criminology perspective. The participants were 38 males incarcerated in two prisons in Israel who had been convicted of various sexual offences. The participants underwent individual in-depth, face-to-face interviews, lasting several hours each. Initially, the findings suggested a tendency for offences to escalate over time, referred to as a “criminal spin”, which can be stopped only by external intervention. Most of the participants also reported that they experienced positive changes during the current imprisonment, associated with broad support received from various sources. This suggests a possible way out of the criminal spin by exposing offenders to the human and social acceptance of meaningful agents, thus supporting the positive criminology perspective. In addition to their theoretical contribution, the findings have practical implications for the assessment, treatment and rehabilitation of sex offenders.  相似文献

24‐hours media     
Democratically elected governments are having to respond to an increasingly media‐driven society. The pressures imposed by 24‐hour news media are unrelenting: growing demands for access and information show no sign of abating. Tony Blair and his personal spin doctor, the Downing Street director of communications, Alastair Campbell, are at the cutting edge in developing media techniques which seem likely to be tested as never before, as democracies around the world have to grapple with astute propagandists like Osama bin Laden.

Francis Fukuyama asks: ‘Is liberal democracy prey to serious internal contradictions, contradictions so serious that they will eventually undermine it as a political system?’ This paper argues that one of these ‘internal contradictions’ is the political communications process and it can be sufficiently serious to undermine the democratic system—but such an undermining is not inevitable.  相似文献

ABSTRACT

Making sure political parties receive comprehensive and favourable media coverage is a full-time activity that extends beyond the period of election campaigns. In the era of the permanent campaign the annual autumn conferences of the main British political parties represent a publicity opportunity. The undivided media coverage of these events provides a platform for the political parties to sell themselves and their policies to a national audience beyond the conference venue, but also presents considerable risks. To ensure that they successfully exploit this publicity opportunity the party managers, with the aid of communication experts, both control the conferences and implement media management strategies. This article examines how the parties have adapted their conferences to sell themselves and their policies. It highlights the public relations techniques that are employed to ensure that party policy gains the desired positive news coverage and that the coverage of potentially damaging events is minimized. It concludes by considering the impact this marketing driven logic has on the party conferences and their media coverage.  相似文献

Abstract

This paper argues that the widely noticed increase in news reports about news management, government publicity and media relations must be seen as a logical outgrowth of a new, modernized and media-centred approach to policy-making and campaigning. It offers a systematic introduction to the concepts of media politics and metacoverage, develops a theoretical model to examine their relationship and applies it to the political communication dynamics of Great Britain. This paper breaks new ground in two respects: it broadens our understanding of what counter-measures media professionals take in response to political news management, and it lays out a comprehensive theoretical scheme of how the mediatization of politics leads to a mediatization of political coverage.  相似文献
