Abstract: A genetic database was established with the aim of documenting the genetic diversity of Cannabis sativa in Australia for future utilization in forensic investigations. The database consisted of genotypes at 10 validated short tandem repeat loci for 510 plants representing drug seizures from across Australia and 57 fiber samples. A total of 106 alleles and 314 different genotypes were detected. All fiber samples exhibited unique genotypes while 55% of the drug samples shared a genotype with one or more samples. Shared genotypes were mostly found within seizures; however, some genotypes were found among seizures. Statistical analysis indicated that genotype sharing was a consequence of clonal propagation rather than a lack of genetic resolution. Thus, the finding of shared genotypes among seizures is likely due to either a common supplier, or direct links among seizures. Notwithstanding the potential intelligence information provided by genetic analysis of C. sativa, our database analysis also reveals some present limitations. 相似文献

Abstract: Plant material is frequently encountered in criminal investigations but often overlooked as potential evidence. We designed a DNA‐based molecular identification system for 100 Australian grasses that consisted of a series of polymerase chain reaction assays that enabled the progressive identification of grasses to different taxonomic levels. The identification system was based on DNA sequence variation at four chloroplast and two mitochondrial loci. Seventeen informative indels and 68 single‐nucleotide polymorphisms were utilized as molecular markers for subfamily to species‐level identification. To identify an unknown sample to subfamily level required a minimum of four markers or nine markers for species identification. The accuracy of the system was confirmed by blind tests. We have demonstrated “proof of concept” of a molecular identification system for trace botanical samples. Our evaluation suggests that the adoption of a system that combines this approach with DNA sequencing could assist the morphological identification of grasses found as forensic evidence. 相似文献

It is a requirement that forensic DNA profiling evidence be accompanied by an estimation of its weight, in order that the court can assign an appropriate probative value to it during legal proceedings. There are various models by which this estimation can be made, but each relies on approximations of the allele frequencies in the relevant population. This report provides the results of population genetic analyses at nine autosomal short tandem repeat (STR) loci for the Aboriginal Australian sub-population of New South Wales, Australia. 相似文献

This article examines the EU's role in the emergence of international development policy in the 10 member states from Central and Eastern Europe (CEE). Development policy provides useful insights into policy making as it is a key way that states operationalise their foreign policy. Thus, development policy gives us insights into the foreign policy priorities of the new member states. This article reviews the emergence and elaboration of policy relating to international development in the new member states and explores how far we have witnessed the Europeanisation of development cooperation in CEE states. 相似文献

This article interrogates the ways in which the United States ‘forgets’ the consequences and effects of its foreign policy in the making of its identity. In particular, the article argues that such forgetting enables the United States government to frame its interventions in world affairs as innocent and morally driven. Literature on collective memory and the forgetting that enables the production of such memory informs one element of the argument. Three contemporary films from the amnesia genre are analysed to provide insights into the kind of American identity forged in the acts of remembering and forgetting, illustrating the argument that remembering and forgetting are complex, voluntary and at times mendacious processes. The article concludes with the observation that the processes of forgetting past action when framing the context of new interventions make the United States a dangerous force in global affairs. 相似文献

Venous air embolism occurs when air enters the venous system. The main causes of venous air embolism include medical procedures, neck and head trauma, and injuries of the genitals. Self‐induced suicidal (and intentional) air embolism is extremely rare. The authors report a rare case of a suicidal air embolism committed using a self‐made tool composed of a plastic bottle and an infusion set, injecting nearly 2000 mL of air into the cubital vein. The toxicological analysis suggested that midazolam, together with air, was also injected into the circulation using the same bottle and infusion set. 相似文献

This paper explores the qualitative perspectives of women about a community embedded fathers’ initiative in Northern England. Projects to improve the well-being of men and their children are less common within the landscape of parent and child support, with mothers more often being the target recipients. Asking women about their perceptions of an initiative for fathers then offers original insights from women who are positioned as ‘related outsiders’, in that they were ‘outside’ the project but ‘inside’ the family and community. Findings suggest that women are able to see the positive impact of such a project, identifying that it offers a shared space for men and children, time for mothers without their children and can help with shifting roles and attitudes around childcare and emotional labour in the home. The initiative was also seen by the women as offering men more healthy means of coping, including men moving away from traditional hegemonic practices, which in turn shifted some women’s long held gendered beliefs about men as fathers. This research then offers a relational gendered backstory to a father’s initiative, demonstrating how such initiatives can potentially ‘undo’ gender and the positive implications this could have for families. 相似文献

Adolescents are constantly connected with each other and the digital landscape through a myriad of screen media devices. Unprecedented access to the wider world and hence a variety of activities, particularly since the introduction of mobile technology, has given rise to questions regarding the impact of this changing media environment on the mental health of young people. Depressive symptoms are one of the most common disabling health issues in adolescence and although research has examined associations between screen use and symptoms of depression, longitudinal investigations are rare and fewer still consider trajectories of change in symptoms. Given the plethora of devices and normalisation of their use, understanding potential longitudinal associations with mental health is crucial. A sample of 1,749 (47% female) adolescents (10–17 years) participated in six waves of data collection over two years. Symptoms of depression, time spent on screens, and on separate screen activities (social networking, gaming, web browsing, TV/passive) were self-reported. Latent growth curve modelling revealed three trajectories of depressive symptoms (low-stable, high-decreasing, and low-increasing) and there were important differences across these groups on screen use. Some small, positive associations were evident between depressive symptoms and later screen use, and between screen use and later depressive symptoms. However, a Random Intercept Cross Lagged Panel Model revealed no consistent support for a longitudinal association. The study highlights the importance of considering differential trajectories of depressive symptoms and specific forms of screen activity to understand these relationships. 相似文献

In ten member states of the European Union (EU) the new constitutional treaty was supposed to be ratified by referendum. A
growing number of theoretical models predicts that such additional ratification hurdles result in an advantage for negotiators
in the bargaining game. The impact such a referendum constraint can exert, however, depends on the timing of its announcement,
the remaining ratification rules as well as the preference constellations. If parliament and voters are actually in favor
of the new treaty, ratification constraints may cease to affect the bargaining outcome. After presenting the theoretical foundation
of these arguments, we present empirical evidence much in line with the theoretical implications. More specifically, especially
for the issues changed during the intergovernmental conference, those governments gained that had scheduled a referendum and
voters had a stronger preference for the status quo.

Previous research has provided mixed results regarding the effect of anxiety on academic achievement. Building on this body
of research, the present longitudinal study pursued two goals. The first goal was to describe trajectories of anxiety during
elementary-school years. The second goal was to determine the predictive value of these trajectories on high school noncompletion
after controlling for personal (i.e., gender, classroom behaviors, and academic achievement) and familial (i.e., sociofamilial
adversity) characteristics. A community sample of 1,817 children (887 boys, 930 girls) participated in this study. Results
showed that anxiety tended to fluctuate from kindergarten to Grade 6 for different groups of children. Furthermore, the result
of a logistic regression analysis indicated that group membership for anxiety predicted high school noncompletion by age 20.
As a whole, these findings suggest that considering heterogeneous developmental patterns of anxiety during elementary-school
years appears quite useful for predicting an important outcome such as high school noncompletion.
