Active self-reflection is a sophisticated and subtle, multi-layered process that requires learning the capacity to constantly self-monitor. These fundamental interactive skills, the core of a competent social worker, are important to work in any context. Using two distinct metaphors, one relating to horses, the other to baseball, the article will explore the importance of developing competency skills and utilize a ‘third eye.’ In current social work education curricula the use of self may not be prioritized, practiced, or well understood. Evidence from human and veterinary medicine as well as social work, are discussed. An example of an undergraduate BSW course using simulated clients and standardized measures is discussed. The paper includes a brief review of the preliminary findings for a small pilot study and the relevance to future research is considered. 相似文献

The problem of estimating ordered quantiles of two exponential populations is considered, assuming equality of location parameters (minimum guarantee times), using the quadratic loss function. Under order restrictions, we propose new estimators which are the isotonized version of the MLEs, call it, restricted MLE. A sufficient condition for improving equivariant estimators is derived under order restrictions on the quantiles. Consequently, estimators improving upon the old estimators have been derived. A detailed numerical study has been done to evaluate the performance of proposed estimators using the Monte-Carlo simulation method and recommendations have been made for the use of the estimators. 相似文献

A challenge for large‐scale environmental health investigations such as the National Children's Study (NCS), is characterizing exposures to multiple, co‐occurring chemical agents with varying spatiotemporal concentrations and consequences modulated by biochemical, physiological, behavioral, socioeconomic, and environmental factors. Such investigations can benefit from systematic retrieval, analysis, and integration of diverse extant information on both contaminant patterns and exposure‐relevant factors. This requires development, evaluation, and deployment of informatics methods that support flexible access and analysis of multiattribute data across multiple spatiotemporal scales. A new “Tiered Exposure Ranking” (TiER) framework, developed to support various aspects of risk‐relevant exposure characterization, is described here, with examples demonstrating its application to the NCS. TiER utilizes advances in informatics computational methods, extant database content and availability, and integrative environmental/exposure/biological modeling to support both “discovery‐driven” and “hypothesis‐driven” analyses. “Tier 1” applications focus on “exposomic” pattern recognition for extracting information from multidimensional data sets, whereas second and higher tier applications utilize mechanistic models to develop risk‐relevant exposure metrics for populations and individuals. In this article, “tier 1” applications of TiER explore identification of potentially causative associations among risk factors, for prioritizing further studies, by considering publicly available demographic/socioeconomic, behavioral, and environmental data in relation to two health endpoints (preterm birth and low birth weight). A “tier 2” application develops estimates of pollutant mixture inhalation exposure indices for NCS counties, formulated to support risk characterization for these endpoints. Applications of TiER demonstrate the feasibility of developing risk‐relevant exposure characterizations for pollutants using extant environmental and demographic/socioeconomic data. 相似文献

This article seeks to demonstrate and analyze the cultural and emotional work surrogate mothers collectively engage in on the largest surrogacy support website, http://www.surromomsonline.com . Surrogate mothers’ online stories and discussions frame contract surrogacy as a “labor of love.” Women often describe their surrogacy as a “journey” of shared love; they hope for a lasting relationship with the couple they carry for. This article explores how the language of love, learned and internalized through online communication with other surrogates, creates both a cultural conceptualization of surrogacy and a ground for action. Love and altruistic giving are consistent with close interpersonal rather than market relationships; surrogates hope for a long‐term friendship with their couple. Surrogacy journeys, however, not infrequently end in disappointment; surrogates feel betrayed when couples cut ties. As a result of collective learning, surrogates’ discussions increasingly articulate the position that love, even when unreciprocated, can lead to repeated giving; love is noble and ennobling. Surrogates find appreciation and support in their online surrogacy community where they agree that giving life is a moral good. This stance has contributed to a renewed enthusiasm to bear children for others. 相似文献

The estimation problem of epsilon-skew-normal (ESN) distribution parameters is considered within Bayesian approaches. This family of distributions contains the normal distribution, can be used for analyzing the asymmetric and near-normal data. Bayesian estimates under informative and non informative Jeffreys prior distributions are obtained and performances of ESN family and these estimates are shown via a simulation study. A real data set is also used to illustrate the ideas. 相似文献

A pilot study of an interactive hazards education program was carried out in Canberra (Australia), with direct input from youth participants. Effects were evaluated in relation to youths’ interest in disasters, motivation to prepare, risk awareness, knowledge indicators, perceived preparedness levels, planning and practice for emergencies, and fear and anxiety indicators. Parents also provided ratings, including of actual home‐based preparedness activities. Using a single group pretest‐posttest with benchmarking design, a sample of 20 youths and their parents from a low SES community participated. Findings indicated beneficial changes on a number of indicators. Preparedness indicators increased significantly from pre‐ to posttest on both youth (p < 0.01) and parent ratings (p < 0.01). Parent ratings reflected an increase of just under six home‐based preparedness activities. Youth knowledge about disaster mitigation also was seen to increase significantly (p < 0.001), increasing 39% from pretest levels. While personalized risk perceptions significantly increased (p < 0.01), anxiety and worry levels were seen either not to change (generalized anxiety, p > 0.05) or to reduce between pre‐ and posttest (hazards‐specific fears, worry, and distress, ps ranged from p < 0.05 to < 0.001). In terms of predictors of preparedness, a number of variables were found to predict posttest preparedness levels, including information searching done by participants between education sessions. These pilot findings are the first to reflect quasi‐experimental outcomes for a youth hazards education program carried out in a setting other than a school that focused on a sample of youth from a low SES community. 相似文献

现有研究普遍认为禽流感的发生会对养禽户家庭生计造成严重负向冲击,而统计数据显示禽流感发生之后养禽户家禽收入显著下降,但家庭收入仍呈上升趋势。 基于农村固定观察点 2 520 个养禽户 2004—2012 年家禽养殖跟踪数据,本文采用固定效应模型,分析禽流感冲击下养禽户家庭生计变化,探讨禽流感、多元化经营与中国养禽农户家庭生计之间的关系。 结果表明,禽流感的爆发确实对家禽养殖农户生计造成了巨大的冲击,但多元化经营可以削弱禽流感对养禽户家庭经营收入的负向影响,且相比于种植业,养禽户更倾向于通过增加畜牧业投入和非农就业投入来避免禽流感造成的家庭经营收入波动。 我国现有禽流感补偿政策仅按照扑杀数量发放,为制定更为精准的扑杀补偿标准和灾后扶持政策,应关注禽流感对养禽户生计冲击的农户异质性,充分考虑养禽户多元化经营状况,扩大政策关注范围,正确引导农户进行兼业经营。 相似文献

The purpose of this article is to explore the origins of dissent public relations and to establish its emergence in the context of the ancient Greek comedy represented by Aristophanes. Indeed, Attic Comedy (also known as Old Comedy) was the first great example of today’s mass communication, in which political satire was used to dissent and protest against political and social circumstances in fifth-century BC Athens. This situation was conditioned by the Peloponnesian War and its political, economic and social consequences. From this perspective, this article also constitutes an investigation into the intellectual history of public relations, of which Aristophanes can be considered to be one of the first practitioners. 相似文献

AbstractIn this paper, we propose a discrete-time risk model with the claim number following an integer-valued autoregressive conditional heteroscedasticity (ARCH) process with Poisson deviates. In this model, the current claim number depends on the previous observations. Within this framework, the equation for finding the adjustment coefficient is derived. Numerical studies are also carried out to examine the impact of the Poisson ARCH dependence structure on the ruin probability. 相似文献
