Neither absolute THC content nor morphology allows the unequivocal discrimination of fiber cultivars and drug strains of Cannabis sativa L. unequivocally. However, the CBD/THC ratio remains constant throughout the plant's life cycle, is independent of environmental factors, and considered to be controlled by a single locus (B) with two codominant alleles (BT and BD). The homozygous BT/BT genotype underlies the THC‐predominant phenotype, BD/BD is CBD predominant, and an intermediate phenotype is induced by the heterozygous state (BT/BD). Using PCR‐based markers in two segregating populations, we proved that the THCA synthase gene represents the postulated B locus and that specific sequence polymorphisms are absolutely linked either to the THC‐predominant or the THC‐intermediate chemotype. The absolute linkage provides an excellent reliability of the marker signal in forensic casework. For validation, the species‐specific marker system was applied to a large number of casework samples and fiber hemp cultivars. 相似文献

The potential for contextual information to bias assessments in the forensic sciences has been demonstrated, in several forensic disiplines. In this paper, biasability potential within forensic anthropology was examined by analyzing the effects of external manipulations on judgments and decision‐making in visual trauma assessment. Three separate websites were created containing fourteen identical images. Participants were randomly assigned to one website. Each website provided different contextual information, to assess variation of interpretation of the same images between contexts. The results indicated a higher scoring of trauma identification responses for the Mass grave context. Furthermore, a significant biasing effect was detected in the interpretation of four images. Less experienced participants were more likely to indicate presence of trauma. This research demonstrates bias impact in forensic anthropological trauma assessments and highlights the importance of recognizing and limiting cognitive vulnerabilities that forensic anthropologists might bring to the analysis. 相似文献

The death of a person as a reaction to the death of another is known as Philemon and Baucis death and may represent a difficult challenge for pathologists, especially due to the decompositional changes that often characterized these situations. In this article, we describe two cases of Philemon and Baucis deaths, the first concerning a married couple and the second concerning a father and son. Postmortem investigations including radiology and biochemistry were performed. Based on the results of all investigations, deaths were attributed to natural causes. Third‐party involvement could be excluded in both situations. In one case, biochemical analysis results revealed potentially contributing causes of death. The reported cases emphasize the importance of correlating findings from different postmortem investigations to identify causes of death, precipitating conditions and predisposing disorders, thus allowing the conclusion of natural death to be reached and third‐party involvement to be excluded. 相似文献

Evidence‐based policy and the contemporary politics of spin are said to characterise contemporary politics and policy. The paper asks firstly what sense is to be made of this coincidence, and then documents this coincidence. It then asks how credible is the conception of ‘evidence’ espoused by advocates of evidence‐based policy when it is conventionally represented as an ‘objective’ counter to ideology, spin or opinion? It points to major problems with the conventional understandings of ‘evidence’. It is suggested that while the evidence‐based policy literature relies on the associations ‘evidence’ is presumed to have with ‘sensory data’, this is neither the case nor all that defensible. The paper reprises arguments advanced by Henry Mayer and Hannah Arendt that the relationship of politics to the empirical was and is a far more complex relationship than is conventionally understood to be the case. 相似文献

In the recent past, several countries and states have begun to use Public‐Private‐Partnerships (PPPs) for infrastructure development and have attempted to create institutional environments that enable PPPs. Providing an enabling environment for PPPs entails a combination of institutional creation and changing existing institutions relating to project procurement. This paper attempts to understand how path‐dependant institutional change takes place in the context of PPPs and their enabling environments, and why different institutional environments evolve differently, using two cases: the implementation of PPPs in the road sector in the Netherlands and in the Indian state of Tamil Nadu. We identify two factors that can be used as predictors of the direction of institutional change: a long‐term orientation towards institutional change and a willingness to learn and modify transitional institutions. Where these factors exist, and thereby provide a goodness of fit, institutional change is likely to occur. 相似文献

Recently in the field of policy studies, there has been a renewed interest in research that connects policy design with broader governance outcomes. As opposed to past studies of policy design that have characterized policies along broad categories of variables, however, recent studies have sought to systematically assess the language of public policies and resultant outcomes. This paper contributes to the existing and emerging literature on policy design by coupling a content analysis of polices governing the aquaculture industry in two U.S. states and interviews with aquaculture community members to understand policy design and perceptions of policy legitimacy, coerciveness, and enforcement. 相似文献

Reliable public sector information serves as a pivotal source for big data. Government postal codes, for instance, have been crucial for predicting demographics. Confidentiality, however, may be at risk when combined with other sources. Public sector information not only describes government activity but contains material, such as campaign finance filings, produced by outside sources. How does information production impact policy concerns if material is reused for big data projects? Information production is analyzed using a framework of five methods of production. The framework considers information that the public sector writes, publishes, manages, produces through research, and compiles through legal mandates. This paper examines the policy implications of using U.S. federal public sector information in big data projects. 相似文献

No‐confidence motions (NCMs) are attempts by opposition parties to publicise the government's failings in a salient policy arena, and previous research has shown that they often negatively affect citizens' evaluations of governing parties' competence and damage their electoral prospects. Yet currently there is a lack of understanding of how opposition parties respond ideologically to these NCMs. It is argued in this article that opposition parties should distance themselves from the government challenged by NCMs to show that they are different from the incompetent government and to compete for the votes that the government is likely to lose. Using a sample of 19 advanced democracies from 1970–2007, empirical evidence is presented that NCMs encourage political parties to move their positions away from the government's position, especially in the presence of reinforcing negative signals about government performance. These results have important implications for our understanding of opposition party policy change, for the economic voting literature, and for the spatial and valence models of party competition. 相似文献
