In the period from 1997 to 2009 Australia experienced a severe drought, which significantly affected the Murray‐Darling Basin. The drought has broken but state governments are still in conflict over water allocations. The establishment of the Murray‐Darling Basin Authority (MDBA) in 2007 was intended to address these issues but the management of the Basin remains complicated by constitutional ambiguity. This paper addresses the question of whether it is possible to implement effective policies for the health of the Murray‐Darling Basin without the present danger of a drought. We suggest that the MDBA has encountered what Beck refers to as the ‘boomerang effect’. The MDBA's plans seem to have produced new challenges and the Authority might find the Basin is exposed to risks it has created.  相似文献

Cobalt(II) thiocyanate-based tests are routinely used to screen cocaine products, with the formation of a blue species interpreted as a positive response. An array of other organic bases has been identified as false positives – including well-documented cocaine product adulterant lidocaine and its salt. False positives prompt continued test development, though improvements are hindered by unresolved product structures and reaction pathways. Toward greater clarity, cobalt(II) thiocyanate reactions with cocaine hydrochloride, along with lidocaine and its salt, were investigated using multiple analytical techniques. Reactions involving cocaine hydrochloride yielded glassy, amorphous blue material while reactions of lidocaine hydrochloride monohydrate produced larger, needle-like crystals whose structure was determined via single-crystal X-ray diffraction to be an ion pair (Hlidocaine+)2([Co(SCN)4]2−)·H2O. While the blue precipitate isolated from reactions involving cocaine hydrochloride was unsuitable for crystallographic structure determination, comparative ultraviolet–visible, attenuated total reflectance infrared, and Raman spectroscopic analysis – along with elemental analysis – supports that this solid is comprised of a comparable ion pair (Hcocaine+)2[Co(SCN)4]2−. Pink crystals isolated from lidocaine reaction vessels were identified as coordination compounds cis-[CoL2(SCN)2] and trans-[CoL2(SCN)2] where L = lidocaine, while pink crystals from both cocaine hydrochloride and lidocaine hydrochloride monohydrate reaction vessels were the coordination polymer trans-[Co(H2O)2(SCN)2]·H2O. The results presented herein enable reaction optimization to favor a desired product, whether ion pair or coordination species.  相似文献

Conventional wisdom in Malawi holds that seasonal food deficits force smallholders to hire out their labour to buy food during the critical first six weeks after planting, thereby reducing maize yields on their own fields and reinforcing poverty. This model was tested empirically for the Blantyre Shire Highlands using evidence from a panel survey and household case studies. Results showed no significant relationship between the supply of hired labour (ganyu) and the timeliness of weeding for maize, and that timely weeding was not a significant determinant of household maize deficits. This puzzle is explained by the diversification of the rural economy that has allowed households to develop alternative livelihood strategies to cope with maize deficits. Livelihood diversity helped poor households avoid the seasonal poverty trap and also helps explain the paradox of why the poorest region in Malawi escaped the 2001–2002 famine.  相似文献

Less than two decades after the end of apartheid, South Africa is witnessing a range of policy interventions that almost iconoclastically challenge the premises of democratic governance. Police military ranks have been reintroduced and an exemplary postapartheid law governing the use of lethal force has also been amended in favor of police discretion. Simultaneously, however, community policing, a benchmark for democratic policing, is being rolled out on unprecedented scale. This article argues that the seemingly contradictory mobilization of militarized policing and popular civilian institutional forms has a definite logic and captures the postcolonial condition of policing in South Africa: a populist‐oriented ANC administration has allowed practices of popular policing underwritten by a desire for a forceful state to capture the law that had previously restrained this kind of policing. The result is a violent but intimate relationship between police and people, a situation in which the law is estranged from itself and normalized into the informal realm of private policing.  相似文献

Abstract

Common factors underlie sexual and non-sexual aggression, and they co-occur at high rates. This study reports on whether Dutton et al.'s model of partner abuse (1994) also predicts sexual offender status. Incarcerated sexual offenders (n?=?144) and non-sexual offenders (n?=?34) completed a voluntary, anonymous survey of attachment, anger and anxiety measures. Sexual offenders produced significantly higher insecure attachment (p?=?0.001), anger (p?<?0.05) and generalized anxiety (p?<?0.01) scores than non-sexual offenders. Intended multivariate analyses were prohibited by multicollinearity between predictors. Although insecure attachment, anxiety and anger distinguish sexual from non-sexual offenders, their predictive power in a multivariate model is yet to be determined. Awareness of the co-occurrence of sexual and non-sexual violence would improve assessment and treatment approaches for professionals in both arenas.  相似文献

Abstract

Sexually abusive behaviour by personality disordered patients presents a serious threat to the integrity of staff–patient relationships and the safety of other residents. The occurrence of such behaviour is also problematic for the offending patient, as it may impact on perceived treatment needs and their access to the community. This paper reports on a study of sexually abusive behaviour in a high security psychiatric hospital. It also examines the relationship between these behaviours and patients’ history of sexual offending. The results showed a high frequency of low-severity sexually abusive behaviour and no significant associations between sexually abusive behaviour during hospitalization and sexual offence history. These findings imply that low-severity sexually abusive behaviour within secure settings may be determined, partly, by environmental conditions. This sexual abuse may also be functionally dissimilar to severe sexual abuse perpetrated in the community. The meaning and determinants of sexual abuse within secure settings must be scrutinized carefully and comprehensively before they are considered analogous to previous sexual offences.  相似文献

This article details the distinctive style and political commitments that Green members of parliament (MPs) bring to representative democracy in Australia. Based on in-depth interviews with 16 sitting federal and state Green MPs, it examines the extent to which the political culture, grassroots organisation and values of this left-libertarian party influence the parliamentary role orientations and legislative behaviour of its MPs, and how this fits with existing research on parliamentary representatives. The analysis reveals mixed results: while the legislative priorities and representative focus of MPs appear to be influenced more by previous social movement and parliamentary experience rather than overarching party orientations, the party's culture has had a strong impact on MPs' views regarding issues of conscience and their style of representation. Drawing on the comparative experience of Green parties throughout Western Europe, this article utilises the prism of role orientations to assess the conflicting imperatives Australian Green MPs face in staying true to their movement origins while their party becomes increasingly professional and influential in the parliamentary arena.  相似文献

The enzyme α-amylase has long been a commonly targeted protein in serological tests for saliva. While being especially abundant in saliva, α-amylase is detectable in vaginal secretions, sweat, fecal matter, breast milk and other matrices. As a result, assays for α-amylase only provide a presumptive indication of saliva. The availability of mass spectrometry-based tools for the detection of less abundant, but more specific, protein targets (e.g., human statherin) has enabled the development of high confidence assays for human saliva. Sample throughput, however, has traditionally been low due to multi-step workflows for protein extraction, quantitation, enzymatic digestion, solid phase cleanup, and nano-/capillary-based chromatography. Here, we present two novel “direct” single-stage extraction strategies for sample preparation. These feature immunoaffinity purification and reversed-phase solid-phase microextraction in conjunction with intact mass analysis of human statherin for saliva identification. Mass analysis was performed on the Thermo Scientific Q-Exactive™ Orbitrap mass spectrometer with a 10-min analytical run time. Data analysis was performed using Byos® from Protein Metrics. Two sample sets were analyzed with a population of 20 individuals to evaluate detection reliability. A series of casework-type samples were then assayed to evaluate performance in an authentic forensic context. Statherin was confidently identified in 92% and 71% of samples extracted using the immunoaffinity purification and solid phase microextraction approaches, respectively. Overall, immunoaffinity purification outperformed the solid phase microextraction, especially with complex mixtures. In toto, robotic extraction and intact mass spectrometry enable the reliable identification of trace human saliva in a variety of sample types.  相似文献
