Despite positive and negative emotions being equally important predictors of adolescent wellbeing, research examining positive emotions is limited. In 4582 adolescents (69.4% females; age M?±?SD?=?14.55?±?1.74 years), we used structural equation modelling to examine associations between self-reported sleep duration and quality with positive affect, negative affect, and happiness, controlling for age and sex. Overall, sleep quality displayed stronger associations with all measures of emotions compared to sleep duration. Shorter sleep was more specifically associated with lower positive emotions (happiness, followed by positive affect), whereas poorer sleep showed stronger associations with negative affect. Protecting sleep duration may promote positive emotions and enhancing sleep quality may reduce mood disturbances. Future research could incorporate both positive and negative emotions to better understand adolescents’ wellbeing. 相似文献

In the DSM-5, the diagnosis of posttraumatic stress disorder (PTSD) has undergone multiple, albeit minor, changes. These changes include shifting PTSD placement from within the anxiety disorders into a new category of traumatic and stressor-related disorders, alterations in the definition of a traumatic event, shifting of the symptom cluster structure from three to four clusters, the addition of new symptoms including persistent negative beliefs and expectations about oneself or the world, persistent distorted blame of self or others, persistent negative trauma-related emotions, and risky or reckless behaviors, and the addition of a dissociative specifier. The evidence or lack thereof behind each of these changes is briefly reviewed. These changes, although not likely to change overall prevalence, have the potential to increase the heterogeneity of individuals receiving a PTSD diagnosis both by altering what qualifies as a traumatic event and by adding symptoms commonly occurring in other disorders such as depression, borderline personality disorder, and dissociative disorders. Legal implications of these changes include continued confusion regarding what constitutes a traumatic stressor, difficulties with differential diagnosis, increased ease in malingering, and improper linking of symptoms to causes of behavior. These PTSD changes are discussed within the broader context of DSM reliability and validity concerns. 相似文献

Color determination of soil evidence is often done by visual comparison to soil color charts. A handheld spectrophotometer was tested with representative materials for its suitability for forensic soil characterization. Instrumental colorimetry provides accurate colorimetry with ~10-fold better precision than a soil color chart. The minimum sample size for accurate color determination was between 0.02 and 0.04 mg of fine soil for the specific instrument tested. Reporting colors in the L*a*b* space permits quantification of ΔE00, a measure of perceptible color difference, could enable objective quantification of small color differences and thresholds for forensic soil comparisons. A ΔE00 greater than ~ 3.5 to 6 likely indicates disparate soil sources in a forensic comparison, in the absence of confounding factors like sample alteration. Despite the superior precision of instrumental colorimetry, this approach is inappropriate for samples which are mottled at an inseparable scale, attached to a substrate, or too small for instrumental measurement. 相似文献

The purpose of this research is to determine if latent fingerprints deposited on the exterior glass surfaces of vehicles, then covered in debris, can be recovered. Past research used liquid latex to lift soot to recover trace evidence. Recently, liquid latex has been used to recover latent fingerprints along the bottom of vehicles. In this study, a total of 216 latent fingerprints were deposited on the exterior windows of three vehicles. Three control and three experimental latent fingerprints were placed on each side window. The vehicles collected debris for either 2, 3, or 4 weeks. After debris collection, liquid latex was applied to the experimental sections. The underlying fingerprints were developed with white granular powder. Control fingerprints were developed directly with white granular powder. A chi-square test revealed a significant difference in fingerprint recovery between the control and liquid latex method (X2 = 9.026, d.f. = 1, p = 0.003). An odds ratio determined that the control method increases the probability of latent fingerprint recovery by 2.68. Fisher's exact test indicated that there is no statistically significant difference between the detail of the recovered control and experimental fingerprints (p = 0.065). This study demonstrates that recovery of fingerprints is possible using the liquid latex method; however, the control method recovers more fingerprints on the glass exterior of vehicles. If latent fingerprints are thought to be present on the exterior glass surfaces of vehicles, the control method should be used to improve vehicle processing by investigators. 相似文献

Parties in coalition governments must address the ‘unity/distinctiveness’ dilemma: how to maintain governing cohesion, while sustaining individual identities. Within the Cameron–Clegg government this is a challenge for both parties, but it is more so for the Liberal Democrats as the junior partner. This paper considers how the Liberal Democrats negotiated this dilemma in relation to ministerial portfolio allocations. While the Liberal Democrat strategy of placing ministers in almost all departments has served the Coalition well in terms of governing unity, it has limited the extent to which they have been able to assert their distinctive contribution to Coalition policy‐making. This is demonstrated through an examination of the Liberal Democrats' influence on Coalition welfare policy. A lack of clear policy contributions is potentially highly damaging to the Liberal Democrats electorally, as it suggests that they have made little substantive contribution to the Coalition beyond propping up their Conservative partners. Accordingly, the paper reflects on lessons for junior partners in future UK coalition governments, suggesting that concentrating ministers within one or two departments may provide a more viable means of carving out a distinctive governing legacy. 相似文献

The aims of National Disability Insurance Scheme (NDIS) are to provide long‐term, person‐centred care and support to all Australians with a significant and ongoing disability, including individuals with an acquired brain injury (ABI). The scheme has significant potential to provide equitable opportunity of access to health and disability services. Historically, however, service provision in remote and outer regional areas of Australia lags behind more densely populated centres. Aboriginal and Torres Strait Islanders living with disability are already significantly marginalised. Further to this, people with an ABI are very often misunderstood and overlooked by disability services, health professionals and governments, and frequently fall victim to the criminal justice system. This paper provides an overview of the state of ABI disability for Aboriginal and Torres Strait Islanders in remote and outer regional settings, and the present sets of barriers they face to obtaining quality care and effective interventions. A significant opportunity has emerged with the advent of the NDIS but equitable benefit can only be achieved if additional and specialised measures are devised and implemented to appropriately screen for, and assess, incidence of ABI; disability services are appropriately resourced to overcome the pre‐existing disadvantage, and education, training and recruitment of Aboriginal and Torres Strait Islanders with the NDIS is undertaken to lead attitudinal changes in community to disability and health services. This paper concludes with recommendations for the NDIS to meet its laudable objectives. 相似文献
