The Meat in the Sandwich: Welfare Labelling and the Governance of Meat‐chicken Production in Australia 下载免费PDF全文
This article critically examines the degree to which higher‐animal welfare label claims change animal welfare regulation and governance within intense meat‐chicken ('broiler') production in Australia. It argues that ethical labelling claims on food and other products can be seen as a ‘governance space’ in which various government, industry and civil society actors compete and collaborate for regulatory impact. It concludes that ethical labelling can act as a pathway for re‐embedding social concerns in the market, but only when it prompts changes that become enshrined in standard practice and possibly the law itself. Moreover, the changes wrought by ethical labelling are small and incremental. Nevertheless, labelling may create ongoing productive tension and ‘overflow’ that challenges the market to listen to and accommodate actors (including animals) on the margins to create ongoing incremental changes. 相似文献

Microaggressions are associated with mental and behavioral health problems and are common experiences for sexual and gender minority adolescents (SGMA). Little is known about the social ecological correlates of family-level interpersonal and environmental microaggressions for SGMA. Utilizing a national sample of SGMA (N?=?1,177), this study (a) identified the frequencies of family-level interpersonal and environmental microaggressions by participant demographics and (b) examined individual-, family-, and structural-level factors associated with interpersonal and environmental microaggressions. Outness to parents, a transgender or genderqueer identity, and higher levels of gender role non-conformity were associated with higher frequencies of interpersonal microaggressions. Higher levels of family-level child maltreatment and religiosity were associated with higher frequencies of interpersonal and environmental microaggressions. State-level non-discrimination protections were associated with lower frequencies of environmental microaggressions. Suggestions for increased individual-level support for gender non-binary adolescents as well as family targeted preventive strategies are discussed. Areas for future research are highlighted. 相似文献

The law and society community has argued for decades for an expansive understanding of what counts as “law.” But a content analysis of articles published in the Law & Society Review from its 1966 founding to the present finds that since the 1970s, the law and society community has focused its attention on laws in which the state regulates behavior, and largely ignored laws in which the state distributes resources, goods, and services. Why did socio‐legal scholars avoid studying how laws determine access to such things as health, wealth, housing, education, and food? We find that socio‐legal scholarship has always used “law on the books” as a starting point for analyses (often to identify departures in “law in action”) without ever offering a programmatic vision for how law might ameliorate economic inequality. As a result, when social welfare laws on the books began disappearing, socio‐legal scholarship drifted away from studying law's role in creating, sustaining, and reinforcing economic inequality. We argue that socio‐legal scholarship offers a wide range of analytical tools that could make important contributions to our understanding of social welfare provision. 相似文献

Despite the apparent role alcohol plays in criminal offences, there is at present no evidence available as to the extent of the problem of intoxicated witnesses within England. To address this lack of research, police officers from seven constabularies completed an online survey addressing issues such as the prevalence of intoxicated witnesses, how officers determine intoxication, the procedures employed and their effectiveness. Officers indicated that intoxicated witnesses were a common, to very common, occurrence with most officers determining intoxication through physical symptoms and the witness’s own admission. In terms of interviewing witnesses, the majority of officers indicated that initial details were taken whilst witnesses were intoxicated, but the evidential interview was taken when sober. Officers also indicated that if the witness was intoxicated then the case was less likely to proceed to court and that officers viewed the witness as less accurate. These findings are considered from a criminal justice perspective and discussed in relation to future research. 相似文献

n‐Ethyl pentylone (NEP) is a chemical substance derived from cathinone. Synthetic cathinones are an evolving group of drugs with stimulating, mind‐altering effects sometimes referred to as novel or new psychoactive substances (NPS). There is scarce information in the medical literature regarding forensic cases in which NEP is detected in toxicological testing. We present four fatalities involving NEP from Alabama in 2017. Deaths were attributed to NEP toxicity in two cases (peripheral blood concentrations of 0.121 and 0.953 mg/L) and injuries caused by gunshot wounds in two cases (peripheral blood concentrations of 0.045 and 0.031 mg/L). One case involving NEP described an individual who exhibited classic CNS‐stimulant induced erratic behavior before being found dead. These cases enhance the forensic literature regarding specific NPS like NEP and provide contextual reference for professionals considering the significance of NEP in toxicological interpretation. 相似文献

The Organization of Scientific Area Committees defines threshold of identification as the minimum concentration of ignitable liquid identifiable from gas chromatographic‐mass spectrometry data using accepted pattern identification criteria. We propose a method for determining this threshold for gasoline based on base peak to qualifier ratios of six compounds. The ion ratios were established for each compound in the neat gasoline. These ratios were then compared to those obtained for gasoline and 98% weathered gasoline both spiked onto burnt nylon carpet at 20 ppt down 0.50 ppt, and recovered from the carpet using headspace extraction (ASTM 1412). Identification was confirmed if the compounds’ ion ratios fell within ±25% of that in the neat sample. We found that ion ratios for all samples were acceptable for six compounds at 1.60 and 0.80 ppt for extracted neat and extracted 98% weathered gasoline, respectively, illustrating potential for incorporating into Quality Assurance Programs. 相似文献

Little is known about the mental health of pregnant women in prison in England or the factors which impact admissions to prison mother and baby units (MBUs). Research from the UK suggests women with more ‘stable’ backgrounds and lower prevalence of mental disorder are more likely to be admitted to prison MBUs. Eighty-five pregnant women were interviewed in eight different prisons. Schedules for the Clinical Assessment of Neuropsychiatry (SCAN) and Edinburgh Postnatal Depression Scale (EPDS) were used to assess mental health; Severity of Dependence Questionnaire (SOD-Q) for drug misuse; Alcohol Use Identification Test (AUDIT) for hazardous drinking; and the Structured Clinical Interview for DSM-IV (SCID-II) to identify personality disorder. Fifty-one per cent of participants had depression and 57% had anxiety. Those who were working prior to imprisonment were more likely to be admitted to MBUs, and those with a prior social services involvement, diagnosis of personality disorder or history of suicidality were less likely to be admitted. The high levels of depression and anxiety can have negative impacts on both the mother and her unborn child. Factors which influence MBU admission suggest those who might benefit most from MBU placement are least likely to be admitted. 相似文献

In 2013, Minnesota's Fourth Judicial District was one of four courts in the country selected by the U.S. Department of Justice, Office on Violence Against Women to receive a Family Court Enhancement Project (FCEP) grant, a multiyear demonstration initiative designed to build the capacity of court systems and partner stakeholders to improve child custody decision making in cases involving domestic violence. The FCEP enabled the project sites to explore, implement, and assess new and innovative court and noncourt procedures and practices. This article is an exploration of the outcomes of this project. 相似文献
