The Australian Government announced in its 2017 budget that it would trial random drug‐testing of recipients of the Newstart Allowance and Youth Allowance in three locations from January 2018. The Prime Minister described it as a policy ‘based on love’, but that sentiment is hard to find in the policy rhetoric, which situates it in a suite of measures designed to ‘ensure taxpayers’ money is not being used to fund drug addictions which are creating significant barriers to employment'. The policy may make it harder for people to buy drugs with their welfare payments, through income management, but research suggests it will not help them overcome addiction and its costs will exceed any savings it generates in income support. Furthermore, the policy perpetuates ‘medicalisation’ of the problem of long‐term unemployment by suggesting it stems from deficiencies in individuals that can be ‘treated’, despite evidence to the contrary. Finally, the policy claims to close loopholes in enforcement of mutual obligation requirements without addressing structural weaknesses in the welfare‐to‐work model. Each of these issues will pose challenges for those charged with implementing the policy.  相似文献

A modified grounded-theory (qualitative) study was undertaken in an attempt to discover the psychosocial processes involved when psychiatric/mental health nurses provide care to suicidal people, and in so doing, to induce the first comprehensive theory of psychiatric nursing care of the suicidal person. The findings highlight that the key psychosocial process (or core variable of the theory) is "reconnecting the person with humanity" and that this has three stages: reflecting an image of humanity, guiding the individual back to humanity, and learning to live.  相似文献

Exposure to media violence is related to anxiety in youth, but the causality of the effect has not been established. This experimental study examined the effects of media violence on anxiety, blood pressure, and heart rate in late adolescents. We also examined whether these responses varied by previous exposure to media and real-life violence. College students (N = 209; M age = 18.74; 75 % female; 50 % Caucasian, 34 % African American, 9 % Asian, 3 % Hispanic, and 3 % other racial minorities) were randomized to view either violent or nonviolent high-action movie clips. Participants reported on their anxiety before and after watching the clips, as well as their previous exposure to violence. Measures of blood pressure and heart rate were taken at baseline and during movie viewing. Participants watching violent movie clips showed a greater anxiety increase than those watching nonviolent clips. Both groups experienced increased blood pressure and reduced heart rate during movie watching compared to baseline. Prior exposure to media violence was associated with diminished heart rate response. Additionally, students previously exposed to high levels of real-life violence showed lower blood pressure increases when watching violent clips compared to nonviolent clips. Thus, relatively brief exposure to violent movie clips increased anxiety among late adolescents. Prior exposure to media and real-life violence were associated with lower physiological reactivity to high-action and violent movies, respectively, possibly indicating desensitization. Future studies should investigate long-term anxiety and physiological consequences of regular exposure to media violence in adolescence.  相似文献

As a new stage in women's political participation, enfranchisement brought new efforts to advance gender equality and women's social position and new organisations were formed of women voters, including the women citizens' associations. Concerns with women's and children's welfare and social reform that had been important to sections of the pre-war women's movement were repositioned alongside the pursuit of an equal franchise, equal pay and opportunities and women's representation, in relation to women's new political status. Study of the women citizens' associations in Scotland supports an account of the period 1918-30 as one of considerable political activity, particularly in developing women's role and influence in relation to established political institutions and civil society. It suggests that the division between ‘old’ and ‘new’ feminisms after 1918, mapped onto the binary of equality and difference, was not necessarily a tension for women's organisations. It gives insight into the meaning of ‘citizenship’ for women activists and how the status, rights and responsibilities of citizenship articulated and shaped a distinctive women's politics, bridging political, civil and social rights.  相似文献

The best predictor of future misbehavior is a history of aberrant and wayward conduct. Even so, few theories attempt to account for time-stable maladaptive pathways. To this end, we advance a theory of stability, what we term Coherence Theory. Coherence Theory conceptualizes stability as an emergent property that occurs when antisocial dispositions, social consequences, and misconduct coalesce within an individual. In this sense, misconduct is viewed as only one component of a larger, overarching and multi-faceted emergent construct we label as “concentrated personal disadvantage.” When these three components coalesce within an individual, temporal stability in maladaptive pathways should be expected. Using nationally representative, longitudinal data from the National Survey of Children, we test specific hypotheses derived from our theory. This study makes use of the first and second waves of survey data (N wave 1 = 2,301; N wave 2 = 1,423). The sample overall was 51% male and 52% white. Our analyses provide tentative support for the proposed theory. Concentrated personal disadvantage was found to emerge when the identified constellation of variables coalesced in individuals, and was found to be relatively stable over a 5 year period for males and females. Coherence Theory challenges traditional theories on the stability of antisocial pathways, offers specific conditions under which high levels of stability are likely, and explains why disruption off of antisocial pathways is so difficult.  相似文献

Abstract:  Imaging is an integral diagnostic tool in mass fatality investigations undertaken traditionally by plain X-rays, fluoroscopy, and dental radiography. However, little attention has been given to appropriate image reporting, secure data transfer and storage particularly in relation to the need to meet stringent judicial requirements. Notwithstanding these limitations, it is the risk associated with the safe handling and investigation of contaminated fatalities which is providing new challenges for mass fatality radiological imaging. Mobile multi-slice computed tomography is an alternative to these traditional modalities as it provides a greater diagnostic yield and an opportunity to address the requirements of the criminal justice system. We present a new national disaster victim/forensic identification imaging system—Fimag—which is applicable for both contaminated and non-contaminated mass fatality imaging and addresses the issues of judicial reporting. We suggest this system opens a new era in radiological diagnostics for mass fatalities.  相似文献

Abstract: Canine biological specimens are often part of the physical evidence from crime scenes. Until now, there have been no validated canine‐specific forensic reagent kits available. A multiplex genotyping system, comprising 18 short tandem repeats (STRs) and a sex‐linked zinc finger locus for gender determination, was developed for generating population genetic data assessing the weight of canine forensic DNA profiles. Allele frequencies were estimated for 236 pedigreed and 431 mixed breed dogs residing in the U.S. Average random match probability is 1 in 2 × 1033 using the regional database and 1 in 4 × 1039 using the breed dataset. Each pedigreed population was genetically distinct and could be differentiated from the mixed breed dog population but genetic variation was not significantly correlated with geographic transition. Results herein support the use of the allele frequency data with the canine STR multiplex for conveying the significance of identity testing for forensic casework, parentage testing, and breed assignments.  相似文献

Abstract: Throughout the United States, clearance rates for arson cases remain low due to fire’s destructive nature, subsequent suppression, and a misconception by investigators that no forensic evidence remains. Recent research shows that fire scenes can yield fingerprints if soot layers are removed prior to using available fingerprinting processes. An experiment applying liquid latex to sooted surfaces was conducted to assess its potential to remove soot and yield fingerprints after the dried latex was peeled. Latent fingerprints were applied to glass and drywall surfaces, sooted in a controlled burn, and cooled. Liquid latex was sprayed on, dried, and peeled. Results yielded usable prints within the soot prior to removal techniques, but no further fingerprint enhancement was noted with Ninhydrin. Field studies using liquid latex will be continued by the (US) Virginia Fire Marshal Academy but it appears that liquid latex application is a suitable soot removal method for forensic applications.  相似文献
