Disposing of items of forensic relevance in bodies of water is one countermeasure offenders can use to avoid detection. The impact of immersion in water has been explored for blood, saliva, and semen; however, few studies have assessed touch DNA. Here we report on the effect of exposure to water on the persistence of touch DNA over prolonged periods of time. To evaluate the persistence of cells from touch DNA, after water exposure, three substrates and two water types were tested: plastic, metal, and ceramic, submerged into seawater or tap water. Diamond™ Nucleic Acid Dye was used to stain cells deposited by touch. Cell counts before and after water exposure were compared to investigate cell loss over time, ranging from 6 hours to 5 days. A logarithmic increase in the percent of cells lost was observed over time when the data for substrate and water type conditions were combined. Substrate type influenced the persistence of cells, with the metal substrate retaining cells longer than plastic or ceramic. The influence of water type appeared dependent on the substrate, with varied cell persistence on metal whereas plastic and ceramic recorded similar cell loss over time between water types. The ability to visualize cells after exposure to water could assist in triaging evidence within operational forensic laboratories and allow for targeted sampling. This proof-of-concept study demonstrated that greater than 50% of cells can persist on various items submerged in aqueous environments for at least 5 days, highlighting the possibility for downstream DNA testing. 相似文献

Condorcet’s paradox occurs when there is no alternative that beats every other alternative by majority. The paradox may pose real problems to democratic decision making such as decision deadlocks and democratic paralysis. However, its relevance has been discussed again and again since the celebrated works of Arrow (Social choice and individual values, 1963) and Black (The theory of committees and elections, 1958). The discussion varies from one extreme to the other: from very relevant to practically irrelevant. This paper tries to bring more clarity to the discussion by reviewing the literature on the empirical relevance of Condorcet’s paradox. Since a definition of the paradox for even numbers of voters and alternatives, and for weak voter preferences is missing in the literature, we first define the paradox clearly and simply. Then, three topics are investigated, namely domain conditions, culture and the likelihood of the paradox, and the empirical detection of the paradox. Domain conditions express regularities in voter-preference profiles that prevent the paradox. Frequent observations of these domain conditions would make Condorcet’s paradox empirically less important. Cultures define probability distributions over the set of voter preferences. Observation of cultures might be a first step to indicate the relevance of the paradox. The empirical detection of the paradox speaks for itself; we will try to identify the number of observations of the paradox so far. The overall conclusion is that the empirical relevance of Condorcet’s paradox is still unsettled. 相似文献

There is a general belief that stranger stalkers present the greatest threat to the personal safety of victims, despite national victimisation surveys and applied research demonstrating that ex-partner stalkers are generally more persistent and violent. The just-world hypothesis offers a possible explanation for this apparent contradiction. The current research used nine hypothetical scenarios, administered to 328 university students, to investigate the assumptions that underlie attributions of responsibility in cases of stalking. It explores whether these assumptions are consistent with the proposed mechanisms of the just-world hypothesis, and whether they vary according to the nature of the perpetrator–victim relationship and conduct severity. Thematic analysis revealed that the victim was perceived to be more responsible for the situation when the perpetrator was portrayed as an ex-partner rather than a stranger or acquaintance. Furthermore, victims were perceived to be more responsible when the perpetrator's behaviour was persistent and threatening. These findings are discussed in the context of the just-world hypothesis and related to the proposed mechanisms by which a person can reinterpret a situation so that the perceived injustice disappears. 相似文献

ABSTRACT The purpose of this article is to shed light on an understudied topic in public administration, namely, commitment to organizational change. Specifically, this study examines the extent to which the quality of the relationship between employees and their managers positively influences employees’ commitment to change. Further, it investigates whether this relationship varies as a function of a person's core self-evaluations, that is, the valence of a person's self-regard. Evidence from a multivariate regression analysis in a public sector organization at the local level in the UK revealed that individuals who have high-quality relationships with their managers are more likely to be accepting of change; this is especially true for individuals with lower levels of core self-evaluations. Implications for theory and practice are discussed. 相似文献

The author submits that the main purpose in the establishment of the Caribbean Court of Justice (CCJ) is to promote the development of a Caribbean jurisprudence, based on the Commonwealth Caribbean's common historic, political, economic and cultural experiences and mutual history. The article examines the role of final appellate courts, noting that judges of such courts must often choose between alternatives which are perfectly capable of being defended as rational, reasonable and consistent with ‘the law’. Factors such as life experiences, socialisation, and backgrounds all play a role in determining the choices that are ultimately made. This is why, the author underscores that ‘it is so important to have a diverse Bench, to have Judges from different backgrounds’. For judges to come close to steering the right course they must have an understanding of the society that gives rise to the legal disputes. They must be grounded in that society. In this respect, the author argues, it is remarkable that the evolution of certain landmark judgments relating to human rights, particularly capital punishment, have been rendered by British judges, sitting and residing in England. The article, which draws on a wealth of jurisprudence, proceeds to examine the original jurisdiction of the CCJ and the role of the Bar in defending the integrity of the Court and the justice system as well as in enhancing the quality of judgments. Finally, it emphasises the need to promote Caribbean jurisprudence and access to local judgments. In this regard, it is lamented that many truly outstanding judgments of Caribbean judges do not receive the recognition they should because, if there is an appeal, they become almost automatically buried beneath the judgments of the higher court. 相似文献

The concept that nature is just and that it can act against its perpetrators is widespread among environmentalists. In the research presented, we show the consequences of sharing just-nature beliefs for reactions toward victims of natural catastrophes. A preliminary qualitative analysis of environmentalist discourse related to victims of Fukushima Daiichi nuclear disaster caused by a tsunami showed that just-nature beliefs were used to justify the Japanese tragedy. In the following three quantitative studies, we demonstrate that the belief in just-nature is related to a diminished tendency to help human beings who suffered from natural catastrophes. Two correlation studies conducted directly after the earthquake in Japan in 2011 on members of ecological organizations (N = 183) and undergraduates (N = 123) showed that just-nature beliefs result in a tendency to help by giving donations for reducing the consequences of nature rather than for human victims of the tragedy. The results were replicated in a correlation study of undergraduates (N = 153) conducted after Hurricane Sandy. 相似文献

A simple method of measuring the impact of North‐South trade on the female intensity of manufacturing is applied to data for developed and developing countries. The results confirm that growth of exports has increased the relative demand for female labour in the South. However, there does not appear to have been a general counterpart reduction in the relative demand for female labour in Northern manufacturing, even among blue‐collar workers. There are several possible reasons for the apparent conflict between these findings and other evidence that in Northern manufacturing females have been disproportionately displaced by trade with the South. 相似文献
