A trauma-informed care (TIC) curriculum was integrated into a school of social work master’s level program. Measures assessed the impact of the curriculum on first and advanced-year students’ knowledge, attitude, self-efficacy, and behavioral intention at the beginning and end of a semester. Initial comparisons show advanced-year students as having more knowledge about TIC, more positive attitudes toward TIC, higher levels of self-efficacy to use TIC approaches, and greater likelihood to engage in TIC behaviors than first-year students. However, by the end of the semester, the latter were equivalent with advanced students on all measures. Results suggest the first-year curriculum provides sufficient background in TIC approaches to allow for significant gains across all areas assessed. However, integration of the TIC perspective within advanced courses needs further assessment.  相似文献

This study examines how the effect of CEO duality on firm performance is affected by two internal governance forces – namely other executives in the top management team and blockholding outside directors. Results based on a longitudinal dataset from the U.S. computer industry were consistent with my hypotheses. Specifically, I found that the effect of CEO duality was negative when the CEO had dominant power relative to other executives and when the board had a blockholding outside director, but was nonsignificant otherwise. This study enriches our understanding of the effect of CEO duality, and helps reinforce the call for the nonduality structure as the default choice and put the burden of proof on those who wish to justify otherwise on special grounds.  相似文献

大学英语交际教学法新思考   总被引:1,自引:0,他引:1  
自20世纪70年代以来,交际教学法已成为国内外语言教学颇受青睐的教学方法。交际教学法主张以具体的交际功能项目为线索来安排教学内容,而不是以语言形式来安排内容,激发学生的学习兴趣,提高了语言运用能力。然而,交际教学法的教材增加了语法学习的困难,为此,同一功能表达形式多样对测试的不利及对教师专业培训要求更高等问题,足以引起英语一线教学同仁们的新思考。  相似文献

Abstract

Purpose: To examine differences in site of death and costs of services by primary diagnosis for patients receiving home-based palliative care as compared to usual care at the end of life verity of illness, service use, and site of death.

Design and Methods: A nonequivalent group design was employed with 298 terminally ill patients diagnosed with cancer, CHF, or COPD enrolled. The treatment group received an interdisciplinary home-based palliative care program and the comparison group received usual Kaiser Permanente services. Data collected included patient demographics, se-

Results: Among all diseases, patients enrolled in palliative care were more likely to die at home. Enrollment in palliative care was significant associated with cost reductions for patients with cancer, COPD, and CHF. No significant difference was found between diagnostic groups in terms of magnitude of cost savings.

Implications: Provision of interdisciplinary home-based palliative care at end of life can effectively increase the likelihood of dying at home for patients with CHF, COPD, and cancer while realizing significant COSt savings.  相似文献

翻译教学应从表层向深层转变   总被引:1,自引:0,他引:1  
以传授所谓“翻译技巧”为目的的传统教学法在翻译教材和翻译教学中仍很常见,其实它是一种只注意语言的表面现象而忽略了语言实质的翻译教学路径,对提高翻译学习者的翻译能力起不到指导作用。本文根据现代翻译学、语言学及外语教学理论,对传统翻译教学法进行剖析,指出其局限性,并提出翻译教学的新思路和一些建设性意见。  相似文献

There are relatively few discussions about measurement error in the accelerated failure time (AFT) model, particularly for the semiparametric AFT model. In this article, we propose an adjusted estimation procedure for the semiparametric AFT model with covariates subject to measurement error, based on the profile likelihood approach and simulation and exploration (SIMEX) method. The simulation studies show that the proposed semiparametric SIMEX approach performs well. The proposed approach is applied to a coronary heart disease dataset from the Busselton Health study for illustration.  相似文献

This paper proposes an optimal combinatorial method for finding groups of industries with relatively large CO2 emissions through industrial relations. Using an economic input–output table, we estimated a non-symmetric matrix describing how much CO2 is emitted in producing the commodity of industry i, which was purchased to produce commodity of industry j, to meet the final demand for a specific commodity. A symmetric strength of relations matrix describing the CO2 emissions associated with the industrial relations was further estimated using the non-symmetric matrix. The strength of relations matrix can be viewed as a representation of the supply-chain network of the final commodity. In this study, we estimated the strength of relations matrix associated with the final demand for automobiles and applied the multiway cut approach using nonnegative matrix factorization to the matrix in order to find environmentally important industry clusters in the Japanese automobile supply chain. According to our empirical results, the optimal number of industry clusters is 19, and 4 industry clusters are playing a key role in CO2 emission reduction.  相似文献

Cooperative relationships between groups are difficult because of the high human capability to differentiate between in-group vs. out-group members. This obstacle exists even when the groups can obtain benefits for themselves from cooperation with other groups (rational cooperation). Based on an interactionist approach, the authors propose that personal (individual differences) and situational (conflicts) factors contribute to rational intergroup cooperation. The authors conducted a preliminary correlational study (Study 1) and an experimental investigation (Study 2). In Study 1, the authors examined, with 105 participants, the psychometric properties of the Spanish version of the Rational–Experiential Inventory (REI), measuring individual differences in information processing. In Study 2, the authors conducted an experimental investigation with 141 participants, testing the role of individual differences and conflict in intergroup rational cooperation. Findings of Study 1 showed that the scale has adequate psychometric properties. Results of Study 2 confirmed that the existence of both manipulated and perceived intergroup conflict reduces the magnitudes of the relationships between rational ability and rational cooperation. In addition, perceived intergroup conflict increased the magnitude of the links from experiential ability and experimental engagement to rational cooperation. Both individual differences and previous conflict have a role in predicting rational intergroup cooperation. According to the interactionist approach, personal and situational factors should be considered in the understanding of intergroup relationships.  相似文献
