Evidence-Based Social Work Practice with Mentally Ill Persons who Abuse Alcohol and Other Drugs

Abstract

The current article outlines a comprehensive approach to evidence-based social work practice, and applies it to persons with severe and persistent mental illness who also abuse alcohol and other drugs. Representative empirical literature is summarized within a framework that delineates the three major functions of evidence-based social work practice: assessment, intervention and evaluation. Assessment protocol, which incorporates the use of valid scales to complement the qualitative interview, is based on domain-specific research that outlines relevant psychosocial risk factors, and highlights those that are amenable to change. Intervention strategies are derived from the growing body of controlled research findings, but flexibility in implementation is recommended to accommodate clients' individual needs and the vagaries of daily practice. Naturalistic evaluation methods are used to capitalize on the use of brief, valid process and outcome measures to augment individual qualitative evaluation and to aggregate data for program evaluation. The implications of this integrated evidence-based strategy for social work practice are discussed.

Comments on specification of household expenditure functions and equivalence scales by nonparametric regression

This paper considers Lagrange Multiplier (LM) and Likelihood Ratio (LR) tests for determining the cointegrating rank of a vector autoregressive system. n order to deal with outliers and possible fat-tailedness of the error process, non-Gaussian likelihoods are used to carry out the estimation. The limiting distributions of the tests based on these non-Gaussian pseudo-)likelihoods are derived. These distributions depend on nuisance parameters. An operational procedure is proposed to perform inference. It appears that the tests based on non-Gaussian pseudo-likelihoods are much more powerful than their Gaussian counterparts if the errors are fat-tailed. Moreover, the operational LM-type test has a better overall performance than the LR-type test. Copyright O 1998 by Marcel Dekker, Inc.     

A Nonparametric Test for Autoregressive Conditional Heteroscedasticity: A Markov-Chain Approach

In this article we propose a nonparametric test for autoregressive conditional heteroscedasticity based on finite-state Markov chains. A simple Monte Carlo experiment suggests that in finite samples it performs comparably to the Lagrange multiplier test under conditional normality and is superior for the t, lognormal, and exponential distributions. As an illustration, we apply both tests to Canadian/U.S. forward foreign exchange data.     

荷银澳元理财产品分析

荷兰银行于09年6月推出一款个人保本理财产品,以澳元对美元的汇率为标的,号称＂涨跌双赢＂,年收益率可高达9%,本文从该产品的性质、该产品对日波动率变动的反应分析、即期汇率与汇率均值有较大差距时的反应分析得出结论,该产品风险很大,这是二元期权的基本特征。     

中国社会阶层话语权模式的嬗变及启示

自秦汉以降,与社会性质的变化相应,中国社会阶层话语权的发展呈现为三种典型的发展模式：中国封建社会阶层话语权模式、中华民国社会阶层话语权模式与二元社会阶层话语权模式。中国社会阶层话语权模式的嬗变给我们重要启示,同时也为当代中国社会均衡阶层话语权模式的建构指明了方向。

带稀疏惩罚的LCNN盲目图像复原

为了加强算法的稀疏性和稳定性,在SCAD基础上提出了一种新的稀疏惩罚函数,并加入到拉格朗日约束神经网络中,以克服传统盲源分离方法和独立分量分析方法的缺陷,有效地避免了方程的病态问题,提高盲目图像复原的稀疏性、稳定性和准确性。通过人工数据和真实数据的不同复原算法对比实验,证明了带稀疏惩罚的拉格朗日约束神经网络盲目图像复原技术具有良好的图像复原效果。
