Differences in health-related quality of life among persons living with HIV/AIDS

We sought to identify differences in health-related quality of life (HRQoL) among a sample of HIV positive individuals receiving case management services in northern Florida. Our study consisted of 97 individuals receiving HIV case management that included 56 males (57.7%) and 81 African Americans (83.5%) who were 47.05 years old (SD = 9.33). HRQoL was measured using the HIV/AIDS Targeted-Quality of Life scale (HAT-QOL). Results show significant group differences in HRQoL by race, income, tobacco use, alcohol use, drug use, and CD4 cell count, despite only 43% of this sample being able to recall their most recent CD4 count. Translating these findings to inform practice, HIV care providers need to provide continuing education to patients about their disease status, knowledge, and treatment as it relates to self-care. Also, HIV care providers should be especially cognizant of the impact that tobacco, alcohol, and illicit drug use has on HRQoL for persons living with HIV/AIDS (PLHA) by working to assess social support, identify readiness for change, and make appropriate referrals for treatment.     

YAG:RE3+(RE=Eu,Tb)的制备及发光特性研究

利用柠檬酸-凝胶方法,以Y2O3,Eu2O3,Tb4O7和Al(NO3)3·9H2O作为初始原料,柠檬酸作为配位剂,成功制备出了Y3Al5O12:Eu3+(Tb3+)发光材料,其烧结温度为1?000℃,时间4?h.通过X射线衍射测试,表征Y3Al5O12为单相;计算其晶胞参数,发现晶胞体积v随着pH值的增大而增大.对Y3Al5O12:Eu3+(Tb3+)系列样品在紫外光谱区域和真空紫外光谱区域的发光性能进行了研究,结果表明:在真空紫外光谱区域激发下,Eu3+(Tb3+)的猝灭浓度比在紫外光谱区域激发下的低.     

The matched pair sign test using bivariate ranked set sampling for different ranking based schemes

Bivariate rank set sample (BVRSS) matched pair sign test is introduced and investigated for different ranking based schemes. We show that this test is asymptotically more efficient and more powerful than its counterpart sign test based on a bivariate simple random sample (BVSRS) for different ranking schemes. The asymptotic null distribution and the efficiency of the test are derived. Pitman’s asymptotic relative efficiency is used to compare the asymptotic performance of the matched pair sign test using BVRSS versus using BVSRS in all ranking cases. For small sample sizes, the bootstrap method is used to estimate P-values. Numerical comparisons are used to gain insight about the efficiency of the BVRSS sign test compared to the BVSRS sign test. Our numerical and theoretical results indicate that using any ranking scheme of BVRSS for the matched pair sign test is more efficient than using BVSRS.     

显示问题式教材编纂法构想

传统的教材编纂法属于＂显示完美式教材编纂法＂,力求显示教材已将相应领域的问题都圆满解决,对于其中存在的问题不有意加以显示,甚至有意加以掩藏,故无法激发学生的创新意识、创新能力,甚或对创新有抑制作用。应采用＂显示问题式教材编纂法＂,力求将相应领域存在的各种问题显示出来,使学生产生创新的意念,明了创新的着力点,从而有力地促进学生创新能力的提高。

对高校辅导员工作的几点体会

高校辅导员是建设良好大学生集体、形成良好学习风气和优良校风的重要组织者和引导者，因此，作为高校辅导员，不仅要明确自身工作在整个学生思想政治工作中的地位和作用，而且要注重丰富知识储备，提高工作素养，从职业伦理责任的高度，积极探索有效促进大学生科学发展的新途径、新方法，努力创新高校辅导员工作新局面。     

Collaborative Responses to the Demands of Emerging Human Needs

Abstract

The paper explores the disintegration and integration which exist between faith and religion and social work and learning. There is a brief explanation of Catholic Papal Teachings and Catholic Social Teaching as a demonstration of de facto concordance between social work and religion. The paper contains citations based on the current social principles of the Catholic Church, several recent papal exhortations and encyclicals. These readings highlight the need for good social work practice. The paper ends with some practical suggestions in ways to promote collaboration between the two fields of endeavor.     

Testing Treatment-Covariate Interaction in a Nonparametric Analysis of Covariance Model

We consider a recently introduced nonparametric model for Analysis of Covariance and derive an asymptotic test for interaction between covariate and treatment. Furthermore, we suggest data depth techniques to obtain joint confidence regions for the covariate effects in this model.

The finite sample behavior of the asymptotic method is evaluated in simulations. Application of the procedures is illustrated using an epileptic seizures and chemotherapy data set.     

Unpacking Within‐Household Gender Differences in Partners' Subjective Benefits From Household Income

The authors examine how contributions to household resources, indicated by employment status, influence satisfaction with household income (SWHI) for members of male/female couples. They take changes in SWHI, which may differ within couples, to indicate changes in perceived benefits from their common household income, benefits that can go beyond individual consumption. Using data from the British Household Panel Survey for 2,396 couples from 1996 to 2007, three gender effects are identified. First, men predominate in making the type of contribution that most positively influences SWHI, namely, full‐time employment. Second, the effect of contributions depends on the gender of the contributor, with men's employment being more influential than women's. Third, within couples, making the more influential contribution, as men tend to do, leads to relatively greater SWHI. The authors conclude that gender asymmetry in contributions made to household resources is one way in which gender inequalities invade and inhabit households.     

An Empirical Comparison of Estimating Methods for the Ramberg–Osgood EIV Model

The standard tensile test is one of the most frequent tools performed for the evaluation of mechanical properties of metals. An empirical model proposed by Ramberg and Osgood fits the tensile test data using a nonlinear model for the strain in terms of the stress. It is an Error-In-Variables (EIV) model because of the uncertainty affecting both strain and stress measurement instruments. The SIMEX, a simulation-based method for the estimation of model parameters, is powerful in order to reduce bias due to the measurement error in EIV models. The plan of this article is the following. In Sec. 2, we introduce the Ramberg–Osgood model and another reparametrization according to different assumptions on the independent variable. In Sec. 3, there is a summary of SIMEX method for the case at hand. Section 4 is a comparison between SIMEX and others estimating methods in order to highlight the peculiarities of the different approaches. In the last section, there are some concluding remarks.
