The English High Court recently refused to grant an injunction to restrain The Times newspaper from publishing the identity of an anonymous political blogger (The author of a blog v Times Newspapers Limited [2009] EWHC 1358 (QB)). The facts of the case were unusual: there was no clearly unlawful behaviour by the blogger, who was also a police officer highly critical of political figures and policies. There was also no relationship between the blogger and the journalist who deduced the blogger's identity; the court therefore focussed on the tort of misuse of private information and countervailing public interests, such as freedom of expression. This article describes the approach of the court and considers the earlier case of Mahmood v Galloway ([2006] EWHC 1286 (QB)) concerning an undercover journalist's attempt to prevent publication of photographs showing what he looked like. It also discusses whether data protection law could have a role to play in future cases concerning attempts to preserve an online author's anonymity. The conclusion of the article is that this case does not spell the end of all anonymous blogging. 相似文献

A study was conducted on decomposition and insect succession in the Prairie Ecozone of Saskatchewan in the year 2000. Eighteen domestic pig carcasses (42-79 kg) were employed as human models for applications to future homicide investigations in this region. Two major variables were considered including the effect of season and habitat (sun versus shade). Research was conducted over 25 weeks, spanning three seasons: spring, summer and fall. Ambient temperature, internal carcass temperature, faunistic succession over time, and the rate of decay were all compared for each experimental variable. Results indicated that habitat was only a factor in the decompositional rate of carrion in the spring season. The ambient temperature was the chief factor determining the seasonal variations in decay rate. Maximum internal carcass temperatures always coincided with the presence of 3rd instar larvae. Patterns of insect succession occurred in a predictable sequence that varied across different habitats and seasons and was unique compared to previously published studies. Carcasses placed in spring and fall attracted a more diverse assemblage of insects than summer-placed carrion. Sun-exposed carrion also had greater variation in fauna than shaded carrion in spring and fall. Members of Silphidae were the first coleopteran colonizers in all habitats and seasons. This paper also marks the first record for Cochliomyia macellaria (Fabricius) in Saskatchewan. 相似文献

Childhood Sexual Abuse,Other Childhood Factors,and Pathways to Survivors’ Adult Relationship Quality
We were interested in understanding how the effects of childhood sexual abuse, in concert with other negative childhood experiences,
were carried forward into adult romantic relationships. Data from 15,831 married or cohabitating individuals were gathered
via the RELATE Questionnaire. Empirical research, attachment theory, and a general model of adult relationship quality suggested
that the path from negative childhood events to adult relationship quality was mediated by a number of individual and relational
affect-laden variables. Results showed that childhood abuse and other family-of-origin variables work primarily through the
adult survivor’s perceptions of the events of his or her childhood. This “current impact” variable, along with the current
level of depression, work through an emotion-laden relationship variable—level of emotional flooding during couple conflict—to
influence the relationship quality outcome variable. Treatment implications are discussed. 相似文献

This article examines the attitudes of sample populations of urban, suburban and rural police officers in New Jersey in regard
to a hypothetical use of force scenario. The aim of the study is to identify similarities and differences in the perceptions
of officers who are faced with the same type of hypothetical situations but who are exposed to different training, procedural
and environmental factors. Police officers in the United States receive different types of training in each state that might
influence their attitudes towards the use of force. A pilot study was conducted comparing two urban police departments from
two different states and showed some differences in the attitudes of the surveyed officers. To further explore these differences,
a more refined look at three police departments in one state (New Jersey) was conducted as part of a doctoral dissertation
of the lead author. Research questions are aimed at identifying the differences in the frameworks for the justification of
force based on a host of variables. The research questions stipulated that there will be some significant differences in attitudes
towards the use of force by the officers, based on physical location of the communities they police. The findings of the study
identified additional factors that might influence the officers’ attitudes. Twelve focus groups, four at each of the sites,
were analyzed and it appears that there may be a geographic and demographic influence on how the officers respond to the scenario. 相似文献

Abstract: Comparability of data over time and between laboratories is a key issue for consideration in the development of global databases, and more broadly for quality assurance in general. One mechanism that can be utilized for evaluating traceability is an inter-laboratory trial. This paper addresses an inter-laboratory trial conducted across a number of Australian and New Zealand isotope ratio mass spectrometry (IRMS) laboratories. The main objective of this trial was to determine whether IRMS laboratories in these countries would record comparable values for the distributed samples. Four carbon containing and four nitrogen containing compounds were distributed to seven laboratories in Australia and one in New Zealand. The laboratories were requested to analyze the samples using their standard procedures. The data from each laboratory was evaluated collectively using International Standard ISO 13528 ( Statistical methods for use in proficiency testing by inter-laboratory comparisons ). "Warning signals" were raised against one participant in this trial. "Action signals" requiring corrective action were raised against four participants. These participants reviewed the data and possible sources for the discrepancies. This inter-laboratory trial was successful in providing an initial snapshot of the potential for traceability between the participating laboratories. The statistical methods described in this article could be used as a model for others needing to evaluate stable isotope results derived from multiple laboratories, e.g., inter-laboratory trials/proficiency testing. Ongoing trials will be conducted to improve traceability across the Australian and New Zealand IRMS community. 相似文献

Permeability and Burglary Risk: Are Cul-de-Sacs Safer? 总被引:1,自引:0,他引:1
That crime is concentrated in space is now accepted as commonplace. Explanations for why it clusters at particular locations
are various reflecting the range of factors which are held to influence crime placement. In this article, we focus on the
role of the permeability of the street network on the location of crime. We first review the research conducted hitherto,
summarising the different approaches to analysis and the findings that have so far emerged. Then we present original analyses
conducted at the street segment level to examine the issues at hand. In contrast to much of the prior research, in this study
we examine the patterns for a large study area in which there is considerable variation in street network configuration. Moreover,
and in contrast to all of the previous research, the approach to analysis takes into account the multi-level structure of
the data analysed. The findings demonstrate that increased permeability is associated with elevated burglary risk, that burglary
risk is lower on cul-de-sacs (particularly those that are sinuous in nature), and that the risk of burglary is higher on more
major roads and those street segments that are connected to them. In the conclusion of the paper we outline an agenda for
future research. 相似文献
