Cohen and Felson??s (Cohen and Felson American Sociological Review 44(4):588?C608, 1979) routine activity theory posits that for a crime to occur three necessary elements must converge in time and space: motivated offenders, suitable targets, and the absence of capable guardianship. Capable guardians can serve as a key actor in the crime event model; one who can disrupt, either directly or indirectly, the interaction between a motivated offender and a suitable target. This article critically reviews the literature on guardianship for crime prevention. Our specific focus is two-fold: (1) to review the way guardianship has been operationalized and measured, and (2) to review experimental and quasi-experimental evaluations and field tests of guardianship. Research on routine activities has had an uneven focus resulting in the neglect of the guardianship component (Reynald Crime Prevention and Community Safety 11(1):1?C20, 2009; Sampson et al. Security Journal 23(1):37?C51, 2010; Tewksbury and Mustaine Criminal Justice and Behavior 30(3):302?C327, 2003; Wilcox et al. Criminology 45(4):771?C803 2007). Evaluations of guardianship-related interventions demonstrate support for the theoretical construct; however, high-quality field tests of guardianship are wholly lacking. Implications for theory and research are discussed. 相似文献
The current study investigated whether differences in loneliness scores between individuals with a distressed personality
type (type D personality) and subjects without such a personality varied by domestic violence victimization. Participants
(N = 625) were recruited by random sampling from the Municipal Basic Administration of the Dutch city of ‘s-Hertogenbosch and
were invited to fill out a set of questionnaires on health status. For this study, only ratings for domestic violence victimization,
type D personality, feelings of loneliness, and demographics were used. Statistical analyses yielded main effects on loneliness
for both type D personality and history of domestic violence victimization. Above and beyond these main effects, their interaction
was significantly associated with loneliness as well. However, this result seemed to apply to emotional loneliness in particular.
Findings were discussed in light of previous research and study limitations. 相似文献
Increasing politicization in EU member states about European issues can be expected to strengthen the impact of attitudes towards Europe on vote choice in European Parliament (EP) elections. At the same time this impact is likely to vary between voters and contexts as a function of political information. This study explores the role of political information in explaining individual and contextual heterogeneity in the degree of EU issue voting. Using a two-step hierarchical estimation procedure to explore both individual and contextual variation, we show that while EU issue voting in the 2009 EP elections is only slightly more pronounced among the politically sophisticated, it is clearly more extensive in contexts that provide higher levels of political information on European matters. 相似文献
The objective of the paper is to examine how firms have dealt with the trade‐off between flexibility and uncertainty that is characteristic for the decision‐making of firms in coping with self‐regulatory initiatives in general and the comply‐or‐explain principle in corporate governance in particular. Using unique data for 126 listed Dutch firms, we find that firms respond to this self‐regulatory initiative by largely complying with the code recommendation, possibly out of fear that the firm's reputation may be damaged. Furthermore, we find evidence suggesting that firms confine themselves to adopting a specific set of code recommendations and use similar arguments to explain non‐compliance. Our findings indicate uniformity in adopting the standard of good governance which is not in line with the logic of corporate governance codes and casts doubt on the effectiveness of this form of soft law. Overall, the paper's findings indicate that more restrictive (regulatory) instruments may be necessary to make firms conform to the spirit of codes. 相似文献
Forensic laboratories do not have the infrastructure to process or store contaminated DNA samples that have been recovered from a crime scene contaminated with chemical or biological warfare agents. Previous research has shown that DNA profiles can be recovered from blood exposed to several chemical warfare agents after the agent has been removed. The fate of four toxic agents, sulfur mustard, sodium 2-fluoroacetate, sarin, and diazinon, in a lysis buffer used in Promega DNA IQ extraction protocol was studied to determine if extraction would render the samples safe. Two independent analytical methods were used per agent, selected from GC-MS, 1H NMR, 19F NMR, (31)P NMR, or LC-ES MS. The methods were validated before use. Determinations were carried out in a semi-quantitative way, by direct comparison to standards. Agent levels in the elution buffer were found to be below the detectable limits for mustard, sarin, sodium 2-fluoroacetate or low (<0.02 mg/mL) for diazinon. Therefore, once extracted these DNA samples could be safely processed in a forensic laboratory. 相似文献
Abstract: In the present study, ultrastructural analysis of mitochondrial deposits (black dots within mitochondria) as a method for the detection of early acute myocardial infarction (AMI) was evaluated. In 24 patients with AMI and six controls, analysis was performed in the heart of infarcted patients and noninfarcted controls. In the infarction area in lactate dehydrogenase (LDH)‐diagnosed AMI, the percentage of positive mitochondria was significantly higher compared to corresponding heart tissue in control patients and compared to noninfarcted areas within these patients. Also in patients with a clinically diagnosed AMI but no LDH decoloration, a significant higher percentage of positive mitochondria was found in the left ventricle compared to controls and noninfarcted areas. In patients with AMI, an increase in mitochondria with deposits was found in the infarction area compared to controls and noninfarcted tissue within the same patient, suggesting that electron microscopical changes in mitochondria can be used for the diagnosis of AMI less than 3 h old. 相似文献
Die Europ?ische Union und die Bundesrepublik Deutschland sind hinsichtlich des Anbaus gentechnisch
ver?nderter Organismen (GVO) sehr zurückhaltend, w?hrend au?erhalb Europas die Zahl
der angebauten gentechnisch ver?nderten Kulturpflanzen stetig zunimmt. Die Anwesenheit von GVO, die
nicht zum Anbau zugelassen sind, in Saatgut ist deshalb ein wiederkehrendes Problem mit wachsender Bedeutung.
Der Beitrag analysiert die dazu vorliegende Rechtsprechung der Verwaltungsgerichte und demonstriert am jüngsten
Fall der Saatgutkontamination (NK603-Spuren in Maissaatgut) die Anwendung des differenzierten Regelungssystems
des GenTG, das den Vollzugsbeh?rden anspruchsvolle Ermittlungsund Abw?gungspflichten auferlegt. 相似文献
Family‐centered care during adolescent detention aims to increase parental participation in an attempt to optimize treatment outcomes. However, little is known about parents’ needs in family‐centered care. To fill this gap, we interviewed 19 purposefully selected parents of detained adolescents using a semi‐structured topic list. Although needs differed between parents, they were generally interested in activities that included spending time with their child. It is important for parents to receive timely information about their child's condition and treatment, detention procedures, and activities in the facility. The outcomes demonstrated that parents expected a two‐way communication based on respect and reliability. 相似文献
Nationality is the legal bond between a person and a state that connotes full and equal membership of the political community. Yet, in the practice of states, not everyone who is admitted as a national enjoys the full package of rights attached, nor the same security of status. The phenomenon of inequality among citizens is particularly apparent when examining the question of how protected the legal bond itself is: citizenship by birth is more secure than citizenship acquired otherwise—such as by naturalisation—and mono citizens are less prone to withdrawal of nationality than persons with dual or multiple nationality. As nationality revocation gains new attention from states as a tool to counter terrorism, prompting much political, public and academic debate, the reality that this measure often applies only to particular sub-groups of citizens demands closer scrutiny. This article explores how law and practice on citizenship deprivation is to be evaluated against contemporary standards of international law. While states justify unequal application of citizenship deprivation measures by invoking the duty to avoid statelessness, this article shows that the application of other international standards such as non-discrimination and the prohibition of arbitrary deprivation of nationality calls into question the legitimacy of citizenship stripping as a security instrument. Finally, the article reflects on the broader implications of the current trend towards greater inequality of citizenship status as a reaction to the perceived threat that terrorism poses to the integrity of the state, discussing how the creation of different classes of citizen is in fact likely to have a deeper and more lasting impact on the foundations of liberal democracies.
