Evaluators are challenged to keep pace with the vast array of Veteran support programs operating in the United States, resulting in a situation in which many programs lack any evidence of impact. Due to this lack of evidence, there is no efficient way to suggest which programs are most effective in helping Veterans in need of support. One potential solution to this dilemma is to reconceptualize program evaluation, by moving away from evaluating programs individually to evaluating what is common across programs. The Common Components Analysis (CCA) is one such technique that aggregates findings from programs that have undergone rigorous evaluation at the level of program components (e.g., content, process, barrier reduction). Given that many Veteran programs lack outcome evidence from rigorous studies, an adaptation to CCA is needed. This report examines cross-sectional data from a pilot study using an adapted CCA across five domains of well-being (i.e., employment, education, legal/financial/housing, mental/physical health, and social/personal relationships). The purpose of this preliminary study is to determine the feasibility of eliciting program nominations and program components from Veterans via an online survey. When coupled with a longitudinal research design, this adaptation to CCA will allow for stronger causal claims about the expected impact of different program components within and across a variety of domains.  相似文献

Research in high‐income countries has identified an array of risk factors for youth antisocial behavior. However, in low‐ and middle‐income countries, despite higher prevalence of offending and antisocial behavior, there is a paucity of prospective, longitudinal evidence examining predictors. South Africa is a middle‐income country with high rates of violence and crime, and a unique social context, characterized by striking income and gender inequality, and increasing number of children orphaned by AIDS. We tested predictors of antisocial behavior at community, family, and individual levels over four years. One thousand and twenty five adolescents from poor, urban South African settlements were assessed in 2005 (50 percent female; M = 13.4 years) and followed up in 2009. The sample analyzed consisted of the 723 youth (71 percent) assessed at both time points. We employed sociodemographic questionnaires and standardized scales. Validity of our antisocial behavior measure was supported by cross‐sectional associations with well‐evidenced concomitants of youth antisocial behavior, including drug taking and truancy. Regression analysis indicated that male gender and experience of community violence, but not poverty or abuse, predicted antisocial behavior. Despite many South African youth experiencing abuse and poverty at the family level, our findings suggest that high levels of violence in communities may be a more important factor contributing to the development of antisocial behavior, particularly among males.  相似文献

ABSTRACT

The effect of iwi community justice panels is assessed using data from seven years of implementation. Panel participants of 1013 are compared to a control group drawn from 73,000 offenders charged with similar offences and propensity-matched by age, gender, ethnicity, offending history and location. The dependent measure is re-harm from offending calculated using the NZ Crime Harm Index. Panel participants did not reduce their rate of offending compared to matched controls. However, there is a significant reduction in harm from post-panel offending, on average by 26.9 ± 21.05 equivalised prison days. The relative reduction is 22.25% of the harm committed by matched controls. Iwi panels are an effective alternative justice resolution. Panel participants are found to re-offend with minor offences and thus any focus on rates of offending would miss the complexity of the restorative justice process that reduces the harm of re-offending.  相似文献

The aim of this article is to analyse the critical success factors (CSFs) behind the successful implementation of sustainable supply chain practices in Indian automobile industry. Supply chain sustainability is a critical and timely topic for the developing country like India that captures increasing concerns over sustainability, whether driven by current legislation, public interest or competitive opportunity. Identification of CSFs responsible for sustainable supply chain practices and evaluating their contextual relationships has the potential to affect future government policy, current production operations and identify new business models. In response to this, this paper intends to identify CSFs based on organisational theory and model them to implement sustainable supply chain practices in Indian automobile industry. Twenty-five CSFs to implement sustainable supply chain practices based on organisational theory are recognised by means of the literature review and in discussions with experts in one case study organisation. A solution methodology based on the interpretive structural modelling (ISM) technique is used to propose a structural model, which not only helps in understanding the contextual relationship among these CSFs, but also in determining their interdependence to implement sustainable supply chain practices. Further, the importance of CSFs has been determined based on their driving and dependence power using MICMAC analysis. Our overarching thesis is that the insights gained are useful for Indian automobile industry and would help practitioners, regulators and academicians to focus their efforts towards implementation of sustainable supply chain practices.  相似文献

This study aims to examine housing typologies for older adults in the light of three qualitatively examined exogenous factors: policy, societal developments, and technology. The developments in inpatient and assisted ambulatory housing facilities for older adults have been mapped from 1945 to 2016 using quantitative data. Using these data, five transition periods can be distinguished. Within the first transition periods, policy factors were tremendously important, while within the later ones, societal influence empowered by technological change became the primarily driving factor. This research shows that the classification of inpatient, assisted ambulatory housing, and outpatient housing may no longer be applicable in its current form.  相似文献

Current approaches to risk management place insufficient emphasis on the system knowledge available to the assessor, particularly in respect of the dynamic behavior of the system under threat, the role of human agents (HAs), and the knowledge available to those agents. In this article, we address the second of these issues. We are concerned with a class of systems containing HAs playing a variety of roles as significant system elements—as decisionmakers, cognitive agents, or implementers—that is, human activity systems. Within this family of HAS, we focus on safety and mission‐critical systems, referring to this subclass as critical human activity systems (CHASs). Identification of the role and contribution of these human elements to a system is a nontrivial problem whether in an engineering context, or, as is the case here, in a wider social and public context. Frequently, they are treated as standing apart from the system in design or policy terms. Regardless of the process of policy definition followed, analysis of the risk and threats to such a CHAS requires a holistic approach, since the effect of undesirable, uninformed, or erroneous actions on the part of the human elements is both potentially significant to the system output and inextricably bound together with the nonhuman elements of the system. We present a procedure for identifying the potential threats and risks emerging from the roles and activity of those HAs, using the 2014 flooding in southwestern England and the Thames Valley as a contemporary example.  相似文献

The rjmcmc package for R implements the post‐processing reversible jump Markov chain Monte Carlo (MCMC) algorithm of Barker & Link. MCMC output from each of the models is used to estimate posterior model probabilities and Bayes factors. Automatic differentiation is used to simplify implementation. The package is demonstrated on two examples.  相似文献

AimTo determine rates and risk factors for third and fourth degree perineal tears (severe perineal trauma) in a Western Australian context.Design and settingA retrospective hospital-based cohort study was performed using computerised data for 10,408 singleton vaginal deliveries from 28 weeks gestation.MethodsWomen with severe perineal trauma were compared to those without. Logistic regression analysis, stratified by parity, was used to assess demographic and obstetric factors associated with perineal trauma.ResultsSevere perineal trauma incidence was 3% (338/10408), 5.4% (239/4405) for primiparas and 1.7% (99/5990) for multiparas (p < 0.001). Adjusted risk factors associated with trauma and common across parity included Asian or Indian ethnicity, shoulder dystocia and assisted delivery. Epidural analgesia (OR 0.72, 95% CI 0.54–0.96), preterm birth (OR 0.40, 95% CI 0.23–0.72) and episiotomy (OR 0.54, 95% CI 0.39–0.74) were protective in primiparas, while episiotomy was associated with increased risk in multiparas (OR 2.01, 95% CI 1.18–3.45). Additional factors among primiparas were occipito posterior (OP) delivery (OR 3.35, 95% CI 1.75–6.41) and prolonged second stage (OR 1.98, 95% CI 1.46–2.68), and among multiparas included gestational diabetes (OR 1.78, 95% CI 1.04–3.03) and birth weight >4000 g (OR 1.86, 95% CI 1.10–3.15).ConclusionParity differences in risk factors such as episiotomy, infant weight, OP delivery, gestational diabetes and prolonged second stage warrant investigation into clinical management. Although rates differ internationally, and replication evidence has confirmed consistency for certain demographic and obstetric factors, the development of internationally endorsed clinical guidelines and further research around interventions to protect the perineum are recommended.  相似文献
