Poor initial planning processes have been implicated in the high failure rate of rural water and sanitation development projects. This article critically examines 17 existing planning frameworks for rural water supply and sanitation projects with respect to key attributes of good planning practice, in order to discover the extent to which these address the elements of planning that relate to sustainability. It identifies sustainability-related factors from the sector that have been recognised as such and incorporated into current frameworks, as well as factors that are not yet well covered, and makes recommendations to practitioners wishing to employ such frameworks.  相似文献

Obesity is a widespread condition affecting modern Americans. The prevalence of obesity has led to questions of how it can affect the skeleton, and if so can it be identified in unknown skeletal material. This study attempts to decipher the effects of activity level and body mass in modern Americans by employing musculoskeletal stress markers (MSM) to estimate osseous responses to workload and body weight. A total sample of 108 skeletons of known activity level and body mass index (BMI) was observed for MSM in the upper extremity (excluding hands). The entheses selected included arm muscles used during the sit-to-stand transition, which is common in most persons, regardless of activity level and BMI. Using the three categories: normal, active, and obese, logistic regression was calculated on MSM to ascertain which markers were the best indicators of these three categories. Numerous muscles of the upper limb were significant predictors of activity level and body mass, although they did not perform much better than chance. MSM may be used as predictors of activity level and/or BMI in forensic contexts; however, they should be used in conjunction with other indications of workload and/or BMI.  相似文献

Given the prevalence and impact of intimate partner violence (IPV) in both community and therapeutic settings, it is vital that the varying typologies of IPV be identified and treated accordingly. The present study sought to evaluate the efficacy of a screening instrument designed to differentiate between characterologically violent, situationally violent, and distressed non-violent couples; focus was placed on identifying situationally violent couples so that they could be invited to participate in a conjoint pyschoeducational workshop. Couples from two samples were assessed to achieve this goal. Situationally violent couples (N = 115) from Sample 1 were screened into the study via a phone interview and participated in an in-home assessment, which assessed self-reported relationship violence. These couples were compared to a previously collected sample (Sample 2; Jacobsen et al. 1994) of characterologically violent, distressed non-violent, and situationally violent couples. The main hypotheses stated that couples from Sample 1 would report less severe relationship violence than characterlogically violent couples from Sample 2, and would report greater amounts of low-level violence than distressed non-violent couples from Sample 2. Additionally, similar rates of both self-reported violence would be seen for situationally violent couples from Samples 1 and 2. Multivariate analyses supported this with the exception that situationally violent couples from Sample 1 did not differ significantly across all domains from distressed non-violent couples in Sample 2. Implications for the screening instrument’s utility in clinical and research settings are discussed.  相似文献

As the United States struggles with national solutions to address climate change, state and local governments have become leaders in both mitigation and adaptation policy. Although a significant and growing body of research targets these policies, most studies have assumed common factors motivating both adaptation and mitigation policy adoption. There remains a need for more research on cities of all sizes, their adoption of specific local policies, the factors motivating those choices, and whether the influences for mitigation differ from those that motivate adaptation. The paper uses data from a new survey of over 200 local governments in eleven states of the Great Plains region, including measures distinguishing between mitigation and adaptation policies. These data are employed to test the relative influence of factors from three areas: the policy environment, the attitudes of governmental actors, and community atmosphere, in explaining observed variation in the adoption of climate change policies.  相似文献

This research comprises two qualitative studies understanding the experiences of (1) convicted sex offenders voluntarily receiving pharmacological treatment to reduce sexual preoccupation and (2) therapists working with these offenders. The studies form part of a research programme evaluating the use of pharmacological treatment with sexual offenders. In study one, semi-structured interviews were conducted with 13 sexual offenders receiving selective serotonin reuptake inhibitors. In study two, interviews were conducted with eight intervention staff with varying levels of experience of working with offenders taking anti-libidinals. Thematic analysis was used and in study one, two main themes emerged: (i) the impact of the pharmacological treatment on prisoners’ daily functioning; (ii) barriers to compliance/engagement. In study two, three main themes emerged: (i) offenders’ reluctance to engage with pharmacological treatment; (ii) challenges for therapists; (iii) pharmacology: ‘just another piece of the puzzle’. Findings are discussed in relation to practice and future research.  相似文献

Research suggests that a lack of family support, low self-efficacy, mental illness, and life stressors increase the likelihood of women using illicit substances during their pregnancies. These risk factors often characterize the lives of women on probation and parole. The current study uses data from a larger study of women on supervision to explore the risk and protective factors of substance use during pregnancy. Results highlight the importance of self-efficacy, mental health treatment, and family support; and suggest avenues for intervention to improve maternal and infant health outcomes.  相似文献

At the beginning of 2008, the United Kingdom Government rolled into the Counter-Terrorism Bill some controversial proposals to reform coronial inquest processes, namely clauses that would provide for "secret inquests". The provisions were heavily criticised both inside and outside Parliament, and took a rocky passage through both the House of Commons and the House of Lords before eventually being abandoned by the government. In 2009 the government again tried to introduce "secret inquests" with the Coroners and Justice Bill, instead ultimately succeeding in establishing what critics have termed a "parallel" system of justice through provisions around "secret inquiries". This move has been seen as subverting the principles of transparency and open justice in the investigation of contentious deaths. This article examines the government's efforts to introduce "secret inquests" and thereafter "secret inquiries" in the context of the United Kingdom's coronial law and purpose, human rights obligations and the ongoing issues around sensitive intelligence, and examines the clash of laws that gave rise to the controversial proposals.  相似文献

Purpose. Deception detection research has mainly studied denials and distortions given by students. This study examined true and false confessions as told by offenders. It was hypothesized that the statement analytic techniques Criteria‐Based Content Analysis (CBCA) and Reality Monitoring (RM) would discriminate truths and lies. Methods. Truthful and deceptive confessions to crime were given by 30 offenders (both women and men) in a within‐subject design. The participants were in prison at the time of data collection, and told the truth about a crime they had committed and been sentenced for. In addition, they made up a lie about a different crime after a few minutes of preparation. The transcribed statements were scored for CBCA and RM criteria. Results. Results showed that neither total CBCA nor total RM scores differentiated between lies and truths. Some individual CBCA criteria, however, showed differences: more self‐deprecations and doubts about own testimony in the told lies, and more unexpected complications in the truths. Conclusions. The results are discussed in relation to statement analysis of offenders’ accounts, individual CBCA criteria, as well as the development of criminal experience and familiarity with the event and setting. Implications for triers of fact and suggestions for future research are considered.  相似文献

Two experiments investigated how mock jurors react to hearsay testimony in a case involving child sexual assault. Participants read a fictional criminal trial summary involving the sexual assault of a 4-(Experiment 2 only), 6-, or 14-year-old female. The summaries were presented in one of four conditions: (a) child condition—the alleged victim testified; (b) hearsay condition—the alleged victim did not testify, but an adult hearsay witness did testify; (c) multiple condition (Experiment 1 only)—both the alleged victim and the adult hearsay witness testified; and (d) no-witness condition—neither the alleged victim nor the hearsay witness testified. The hearsay testimony was believed to a considerable degree, and this testimony led to an increase in the perceived guilt of the defendant. Moreover, these results were comparable to those of conditions in which the alleged victim testified. The results are discussed in terms of the psychosocial factors affecting the perception of hearsay testimony in a child sexual assault trial.  相似文献

The issue of "insanity" is rarely alluded to in the area of civil law. As a consequence, the legal standard for insanity is not clearly understood by many psychiatrists. The standard derives from case law and is based upon statutory law in the criminal sector. A civil case will be presented where the question of "insanity" was raised. In this case an individual committed suicide and his insurance company refused to pay the beneficiaries of his life insurance policy based upon a provision in his policy that excluded payment in situations of suicide. His beneficiaries sued, claiming that the deceased was insane at the time of his suicide and therefore not responsible for his actions. The standard for insanity in New Jersey and the reasoning of the psychiatrists will be presented.  相似文献
