Abstract The law has experienced great difficulty in defining ‘stalking’ and framing legislation to deal with the problem. There has been little research as to how the public in general and potential victims in particular view this phenomenon. In an effort to explore this issue, 80 women aged 18 to 55 years were invited to classify which of a range of intrusive behaviours were exemplars of stalking. A cluster analysis of the classification data showed a clear distinction between those which participants felt to be stalking and non-stalking related acts. Further, a number of distinct sub-categories of perceived stalking behaviours were suggested by the analysis. Participants were also asked to indicate whether they had first hood experience of any of these behaviours and to describe their worst personal experience of ‘stalking’. Analysis of this data suggested that instances of what our respondents perceived as ‘stalking’ was widespread in the sample and that some of its more serious manifestations would, if reported, have led to criminal charges. The difficulties of framing legislation, however, to define all the acts which our respondents saw as ‘stalking’ remain. 相似文献
Abstract One response to the incentives provided by the Community Reinvestment Act of 1977 (CRA) has been for lenders and community groups to enter into CRA agreements, which involve pledges to provide prescribed levels of service to targeted neighborhoods. This article examines whether lenders actually change their behavior after entering into these agreements. Using data on CRA agreements and on mortgage lending, we find that institutions increase their lending activity with each year an agreement is in force and that increased lending persists after an agreement expires. Additional analysis shows that agreements that include provisions for mortgage counseling and technical assistance are associated with increased targeted lending. By contrast, agreements with provisions requiring small business counseling and technical assistance and periodic meetings by review committees are associated with somewhat depressed lending levels. Further research is needed to draw definitive implications from this second set of results. 相似文献
This paper provides a summary of our report for the National Academy of Sciences, Engineering, and Medicine on proactive policing. We find that there is sufficient scientific evidence to support the adoption of many proactive policing practices if the primary goal is to reduce crime, though the evidence base generally does not provide long-term or jurisdictional estimates. In turn, we conclude that crime prevention outcomes can often be obtained without producing negative community reactions. However, the most effective proactive policing strategies do not appear to have strong positive impacts on citizen perceptions of the police. At the same time, some community-based strategies have begun to show evidence of improving the relations between the police and public. We conclude that there are likely to be large racial disparities in the volume and nature of police–citizen encounters when police target high-risk people or high-risk places, as is common in many proactive policing programs. We could not conclude whether such disparities are due to statistical prediction, racial animus, implicit bias, or other causes.
Marijuana, a drug derived from the Cannabis sativa L. plant, is the world's most consumed illicit drug. In this paper, a total of 156 marijuana samples seized in the state of Espírito Santo (ES), Brazil were studied and analysed by proton nuclear magnetic resonance (1H NMR) spectroscopy to identify the major cannabinoids present. A crude extract of all samples was purified using high performance liquid chromatography so that these compounds could serve as reference substances. Nine fractions were obtained and analysed by 1H NMR and gas chromatography–mass spectrometry (GC–MS), with five presented cannabinoids. ?9-THC (Δ9-trans-tetrahydrocannabinol), ?9-THCA (?9-tetrahydrocannabinolic acid), ?8-THC (?8-tetrahydrocannabinol), 11-hydroxycannabinol, CBV (cannabivarin), and CBN (cannabinol) were found, and their chemical structures were confirmed by GC–MS. The latter compound was obtained with high purity (≈100%), while the others were obtained as less complex mixtures with purity higher than 75% (except for Δ8-THC). Principal component analysis (PCA) was used on the 1H NMR spectra of the 156 samples, and it was found that the samples were grouped according to the months, differentiating into two groups (from July 2014 to January 2015 and from February 2015 to July 2015), where non-grouping was observed from four macro-regions of the ES state (North, Central, Metropolitan, and South). The chemical profile of the seized samples was correlated to the 1H NMR spectrum of an isolated CBN sub-fraction, in which the group formed by samples seized in the year 2015 presented lower CBN content in the chemical composition. From the PCA score plot, two groups of samples were confirmed using the partial least squares discriminant analysis and orthogonal projections to latent structures classification methods. 相似文献
An on-site oral fluid drug screen, Oratect®, was used to investigate the effects of adulterants and foodstuffs on oral fluid test results. Common foods, beverages, food ingredients, cosmetics and hygienic products were demonstrated not to cause false positive results when tested 30 min after their consumption. Evaluations of two commercial oral fluid adulterants, “Clear Choice® Fizzy Flush™” and “Test’in™ Spit n Kleen Mouthwash” suggest their mechanism of action is the clearing of residual drugs of abuse compounds through rinsing of the oral cavity. They do not directly destroy the drug compounds or change the pH of the oral fluid. It is also suggested that a common mouthwash would perform similar action. 相似文献
Debates about optimal farm structure and size have a long history in agricultural economics. Agricultural and development economists argue for an inverse relationship between farm size and productivity, but debates around this remain inconclusive. This article provides a case from maize production in Babati District, Tanzania. The efficiency level of 122 sampled smallholder farmers was estimated and found to be 62.3%, suggesting 37.7% of inefficiencies. A U-shape relationship between plot size and efficiency scores was found. There was high efficiency at plots <2?ha, compared to 2?ha and 3?ha, followed by efficiency at plots >4?ha. Policies stimulating small- and large-scale farms in the country are imperative. 相似文献
Are career politician members of parliament (MPs) more or less likely to vote against the party line than their peers? Despite growing interest in the behavior of career politicians across parliamentary systems, answers to this question are marked by considerable theoretical and empirical uncertainty. I derive the two most common (but opposing) behavioral predictions before testing them over all legislative votes of two UK House of Commons terms (2005–15) using multilevel modeling of new and disaggregated data on MPs' occupational backgrounds. The finding that career politicians are more likely to rebel challenges conventional wisdom and provides an important empirical foundation for the ongoing debate. 相似文献
