Analysis of the image repair discourse in the Michael Phelps controversy

The following study reviews the image repair strategies used by Olympic swimmer Michael Phelps, his sponsors and the organizations that govern him as an amateur swimmer after a picture of Phelps allegedly smoking from a marijuana pipe appeared in a British tabloid. Additionally, the study reviews media coverage of the controversy to determine whether Phelps was successful in repairing his image. The study concludes that Phelps’ image repair campaign was a success. Implications for public relations practitioners and suggestions for future research also are discussed.     

住宅特征价格分析——以广州为例

以广州二手交易的596个高层楼盘、3703个交易样本为研究基础，采用特征价格法测度了影响广州市住宅价格的主要因素，它们分别是与商业中心的距离、与山江公园的距离、与地铁的距离、噪音、户型间隔、装修档次、朝向、楼层、楼龄、阳台数量10项因素，并给出了影响因素的隐含价值。     

Generalized Linear Models

The importance of random number generators has increased over the years. This follows from the fact that contemporary research methods rely more and more on simulation and the increased importance of encryption technology. The output of a random number generator is created by either an algorithm or a physical device. The most popular method for random number generation is through the use of an algorithm. This article presents a new category of physical random bit generator that is packaged by several manufacturers. A statistical analysis of the output from the generators is given.     

Are There Homeless Youth in My Community? Differences of Perception Between Service Providers and High School Youth

While teen homelessness, like all homelessness, is increasing, there have been few solid estimates of the actual number of teens effected. A twofold methodology to count homeless teens was used in the Seacoast region of New Hampshire and Maine. Social service agencies were contacted to obtain a count of homeless adolescents, and over 3000 high school age teens were surveyed in the seacoast ofNew Hampshire and southwestern Maine to identify how many were homeless. By using different definitions of homelessness, it was found that a minimum of 5% of all teens in high school reported that they had been homeless sometime during the past year. When using a broadened definition of homelessness, it was found that 20% of the teens regularly stayed with others. However, this experience was not identified by social service providers, who reported that teen homelessness simply was not a problem in their communities. In order to more accurately describe the phenomenon experienced by teens, it is proposed that the term “homelessness” should be replaced with a more inclusive word, such as “housing distress.”     

Theory and Research in Teaching. Arno A. Bellack,Editor. New York: Teachers College,Columbia University, 1963. 122 pp. $2.50 Softbound

This study compares the efficacy of experimental, competency-based methods of teaching the interpersonal skills of empathic communication, respect, and genuineness with traditional didactic methods. An experimental design using randomly-chosen experimental and control groups of first-year graduate students was employed. Experimental conditions involved communication laboratories consisting of didactic and experiential learning opportunities organized in a systematic and sequential fashion. The findings supported the hypothesis that the experimental groups would significantly outperform the control groups on the criterion variable. A second hypothesis, that the control groups would not achieve significant gains, was refuted.     

Simulated Clients in a Group Practice Course: Engaging Facilitation and Embodying Diversity

Social work students need to develop practice skills with racially and ethnically diverse clients. Previous research has found benefits to using individual simulated clients, and working with a group would not only provide facilitation opportunities, it could also increase students’ exposure to diversity. This article presents a social work group practice class that used simulated clients and the evaluation of the pedagogy using a mixed-methods design. Students’ scores on the Diversity and Oppression Scale significantly improved from pretest to posttest. Focus groups clarified the impact. The results of this exploratory pilot study suggest that this approach allowed students to learn to manage emotional responses, promoted student insights, and provided opportunities to challenge student assumptions.     

Use of Professional and Informal Support by Black Men with Mental Disorders

This study utilized data from the National Survey of American Life to investigate the use of professional services and informal support among African American and Caribbean black men with a lifetime mood, anxiety, or substance use disorder. Thirty-three percent used both professional services and informal support, 14% relied on professional services only, 24% used informal support only, and 29% did not seek help. African American men were more likely than to rely on informal support alone. Having co-occurring mental and substance disorders, experiencing an episode in the past 12 months, and having more people in the informal network increased the likelihood of using professional services and informal supports. Marital status, age, and socioeconomic status were also significantly related to help-seeking. The results suggests potential unmet need. However, the reliance on informal support also suggests a strong protective role that informal networks play in the lives of black men.     

Experiment-dependent priors in psychology and physics

Sometimes conducting an experiment to ascertain the state of a system changes the state of the system being measured. Kahneman & Tversky modelled this effect with support theory. Quantum physics models this effect with probability amplitude mechanics. As this paper shows, probability amplitude mechanics is similar to support theory. Additionally, Viscusi's proposed generalized expected utility model has an analogy in quantum mechanics.
