Since the work of Schumpeter, entrepreneurship has been regarded as a concept that is in close relation to innovation. However, recent country level investigations show that technology innovation and new business creation can be regarded as two separate phenomena. In this paper we provide an explanation for the above contradiction through the distinguishing between two types of entrepreneurship, necessity and opportunity entrepreneurship. Building on opportunity theory and rational choice theory, we investigate the influence of both types of entrepreneurship on country-level innovation, and furthermore, pay particular attention to the interaction between opportunity entrepreneurship and the amount of opportunities available. We find that necessity entrepreneurship is inversely related to country-level innovation, whereas opportunity entrepreneurship is positively linked to technological progress. The positive effect of opportunity entrepreneurship, however, diminishes with an increased amount of entrepreneurial opportunities. This interaction indicates that opportunity availability is an important element of a country’s entrepreneurship environment.  相似文献

Structured risk assessment has become a part of routine practice in forensic settings. However, little attention has been paid to the clinical applicability of existing tools. The present research focused on the performance of the Historical Clinical Risk Management-20 (HCR-20) – one of the most commonly used tools for structured professional judgment – in the daily practice of three medium security units in Flanders. Areas under the curve for the prediction of violent recidivism during (N?=?168) and after (N?=?105) medium security treatment were non-significant. In addition, analyses showed that the HCR-20 was mainly of interest in identifying low-risk individuals. Further research measuring different aspects of predictive validity in applied settings is recommended.  相似文献

Psychometric symptom validity assessment is becoming increasingly part and parcel of psychological and neuropsychological assessments. An unresolved and rarely addressed issue concerns the differentiation between factitious and malingered symptom presentations: present-day symptom validity tests can assess whether an examinee presents with noncredible symptomatology, but not why an examinee does so. We explored this issue by developing the Symptom and Disposition Interview (SDI); a symptom validity test that incorporates strategies intended to gauge internal incentives associated with factitious disorder. The merits of the SDI were explored and compared to a traditional symptom validity test (the Structured Inventory of Malingered Symptomatology) in two analogue studies, each with factitious and malingering conditions (n = 24–30 per condition) and a clinical control group (n = 34, n = 40). Overall, the results were positive: The SDI was as effective in detecting feigned symptom presentations as a traditional symptom validity test and superior in differentiating factitious from malingered symptom presentations. We conclude that the SDI is not ready for clinical use, but that psychometric approaches to the assessment of factitious symptomatology, such as the SDI, appear sufficiently promising to warrant future research.  相似文献

Analyses from international and nongovernmental organizations have pointed to the negative environmental, economic and social implications of the sizable subsidies handed out by governments for the production and consumption of fossil fuels. Given their relevance for achieving climate policy objectives, it is perhaps surprising that the climate regime established by the United Nations Framework Convention on Climate Change (UNFCCC) does not address fossil fuel subsidies. This article discusses the possible role of the UNFCCC in tackling fossil fuel subsidies. It suggests that the UNFCCC could enhance the transparency around fossil fuel subsidies and put in place incentives for countries to undertake subsidy reform. However, the possibilites under the UNFCCC will be limited by political barriers to subsidy reform at the national level and will need to be carried out in coordination with other international institutions active in the field.  相似文献

Enforcement agencies increasingly disclose or “name and shame” corporate offenders. This article uses responsive regulation as a framework for an empirical study of the impact of non‐anonymous publication of sanctions in the Dutch financial market. These publications are characterized as “naming without shaming”, because they are used for technical guidance rather than with the intention to shame. The findings show that naming offenders functions as a general deterrent in the market for financial intermediaries, but considerably less so in the capital market. In both markets, the publication of sanctions weakened the impact of enforcement. In the capital market, the publications neutralized the seriousness of offenses and contributed to the image of the regulator as powerless. In the market for financial intermediaries, naming offenders was perceived as stigmatizing shaming and led to defiance, rather than compliance. The case study suggests, however, that the publication of sanctions may provide an opportunity for guidance, provided they contain a moral message, rather than technical instruction.  相似文献

Objectives

To examine (1) the long-term effects on reoffending of an individual SST for juvenile delinquents in The Netherlands and (2) whether effects differ by demographic and offense history characteristics.

Methods

The present study is a follow-up of a matched control study comparing post-treatment effects of N?=?115 juveniles receiving Tools4U, an SST with a parental component, to N?=?108 control group juveniles receiving treatment as usual (TAU). Analyses were conducted separately for delinquents and truants. Effects in terms of recidivism were assessed using official delinquency data after 6 and 12 months and 1.46 years after SST termination. Percentage of recidivists, number of re-arrests, and violent recidivism were outcome variables.

Results

Overall, 39% of the juveniles reoffended, and there were no differences between Tools4U and TAU on any of the selected recidivism outcomes. Additionally, demographic and delinquency characteristics and post-treatment effects did not moderate effectiveness.

Conclusions

Tools4U was not more effective than TAU in preventing recidivism, which may be explained by a generally low percentage of recidivists. With established treatment integrity, and a lack of well-researched effective treatment alternatives, Tools4U could still be a reasonable treatment option for adolescent onset juvenile offenders, although more research is needed to confirm this.

Police officers are frequently confronted with various stressors that may affect their mental health. Psychological resilience may protect against these effects. For this purpose, a Mental Strength Training (MST) was developed by the Dutch Police Academy aimed at psychological resilience enhancement. The present three-wave study examined efficacy of this training using a quasi-experimental study design among police officers (N Total ?=?305, n Experimenal ?=?138, n Comparison ?=?167). Additionally, we compared between officers in the experimental and comparison group recently confronted with a potentially traumatic event (N Total ?=?170, n Experimenal ?=?74, n Comparison ?=?96). Questionnaires on resilience (Mental Toughness Questionnaire-48 (MTQ-48) and Resilience Scale-nl (RS-nl)), mental health disturbances (Symptoms CheckList 90-R (SCL-90-R) and Self-Rating Inventory for PTSD (SRIP)), were administered pre-training, and about 3 and 9 months post-training. Mixed-effects models showed training effects on Interpersonal Confidence. Similar analyses among officers with recent potentially traumatic event experience showed significant training effects for the RS-nl subscale of Acceptance of Self and Life, MTQ-48 total score, and the MTQ-48 subscale of Interpersonal Confidence. However, all effects yielded small effect sizes according to Cohen’s d, and are therefore of limited practical relevance. Officer’s appraisal of training benefits on resilience enhancement was largely negative. We found no indications that 4-day training substantially improved officer’s psychological resilience or mental health.  相似文献

In this paper, I introduce the Forensic Field Map (FFM) that provides a two-dimensional view on the forensic field. This field is by definition very broad, encompassing a wide range of scientific areas and activities. The forensic work that supports solving criminal cases ranges from recognizing and preserving traces at crime scenes to explaining forensic results as expert witness in court. This goes hand in hand with the development of scientifically based methods and tooling as well as legal, forensic and laboratory procedures. Although the FFM came into being while developing a (visual) framework for digital forensic investigations, the framework turned out to be generically applicable to other forensic disciplines.  相似文献

This paper examines the hypothesis that litigants' perceived procedural justice is positively associated with their trust in judges. We argue that although this association might seem quite robust, it can vary across contexts. In particular, we suggest that the nature and magnitude of the association between procedural justice and trust in judges depends on outcome concerns, and other sociolegal moderators such as outcome importance and prior court experience. We tested our predictions in three different types of law cases among 483 litigants at court hearings of the district court of the Mid‐Netherlands. As predicted, our results indicate that perceived procedural justice was positively associated with trust in judges when outcomes were relatively favorable, and that this association was even stronger when outcomes were relatively unfavorable. The courtroom context studied here enabled us to explore how other sociolegal variables moderated these relationships.  相似文献

As of 2012, the Russian State Duma passed a string of repressive laws on nongovernmental organizations (NGOs), surveillance, and high treason. Under this “new authoritarian” regime, a growing number of Russians are investigated by the security services or put on trial for high treason. NGOs face selective prosecution and surprise inspections. While we know how lawyers use legal mobilization in democratic regimes where they can expect courts to be fair, legal mobilization remains understudied in regimes moving toward authoritarianism, where authorities pass repressive laws but enforce them erratically. Drawing on interviews with Russian lawyers, this article examines how lawyers represent two victim groups of state coercion: Russians under investigation for treason and prosecuted human rights NGOs. By examining how lawyers make strategic choices while coping with unfair courts, the random enforcement of laws, and shrinking resources, this article argues that state coercion does not deter lawyers from legal mobilization at domestic courts and the European Court of Human Rights. Instead, repressive laws push lawyers to reinvent their everyday practices to counter repressive legislation and conviction bias in the criminal justice system.  相似文献
