A Portrait of Older Homeless Men: Identifying Hopelessness and Adaptation

Using participant observation as a homeless shelter volunteer and through face-to-face long interviews with four homeless elders (50+) and six service providers throughout the Greater Cincinnati Metropolitan area, data revealed unique coping strategies and patterns of service use of older homeless people. A state of hopelessness characterized many older homeless people who adapted and functioned in their culture of poverty. Sources of hopelessness were identified. Unique adaptations were noted for certain individuals who either learned to use the services opportunities provided or learned to exploit/abuse the service network. This group of people have found a social niche in which they can function and meet basic survival needs.     

Possible Selves Among Urban Youths of Color: An Exploration of Peer Beliefs and Gender Differences

Drawing from possible selves theory (H. Markus & P. Nurius, 1986), this study explored the roles of peer beliefs about school and gender differences in the development of academic and occupational visions of the future among 216 urban youths of color. Peer beliefs were not related to career and educational possible selves. No gender‐based differences were found in educational possible selves; however, boys were more likely to report hoped‐for and expected possible selves with lower occupational prestige than were girls. Directions for future research and the implications for practice in counseling urban youths of color are discussed.     

The effects of physical activity and sedentary behavior on cognitive health in older adults

Physical activity has been shown to be positively associated with cognitive health, but the mechanisms underlying the benefits of physical activity on cognitive health are unclear. The present study simultaneously examined two hypotheses using structural equation modeling (SEM). The depression-reduction hypothesis states that depression suppresses cognitive ability and that physical activity alleviates dysphoric mood and thereby improves cognitive ability. The social-stimulation hypothesis posits that social contact, which is often facilitated by socially laden physical activities, improves cognitive functioning by stimulating the nervous system. Sedentary behavior in the absence of physical activity is expected to exert an inverse relationship on cognitive health through each of these hypotheses. Community-dwelling elders (N = 158) were administered a variety of measures of cognition, depression, social support, and physical activity. SEM techniques provided partial support for the social-stimulation hypothesis and depression-reduction hypothesis. Implications for treating depression and improving cognitive functioning are discussed.     

Predictors of falling in older Maryland drivers: a structural-equation model

Falls can impair health and reduce quality of life among older adults. Although many factors are related to falling, few analyses examine causal models of this behavior. In this study, factors associated with falling were explored simultaneously using structural-equation modeling. A variety of cognitive, physical-performance, and health measures were administered to 694 older adult drivers from the state of Maryland. The observed and latent variables of age, cognitive ability, physical functioning, health, and falling behavior were used to create a causal model. The model revealed that being older was associated with declines in cognition, and such cognitive declines predicted increased falling. Similarly, poorer health was related to poorer physical functioning, which, in turn, also predicted increased falling. This model indicates that in addition to existing fall-prevention interventions aimed at improving physical functioning, interventions to improve cognition and health might also be effective. It is speculated that fear of falling, which often results in reduced mobility among older adults, might account for the lack of a direct relationship between age and falling. This hypothesis should be examined in further research.

Developing a Career in the Practice of Statistics: The Mentor's Perspective

The W.J. Dixon Award for Excellence in Statistical Consulting is given by the American Statistical Association to “a distinguished individual who has demonstrated excellence in statistical consulting or developed and contributed new methods, software, or ways of thinking that improve statistical practice in general.” In this article, five of the seven past recipients of this career-capping award share their experiences and perspectives through 10 stepping stones that move a practicing statistician from consultant to collaborator to leader. We highlight the need for mentorship throughout the discussion, and provide direction for statisticians who would like to incorporate this advice into their careers.     

PRICING AUSTRALIAN S&P200 OPTIONS: A BAYESIAN APPROACH BASED ON GENERALIZED DISTRIBUTIONAL FORMS

This paper develops a new class of option price models and applies it to options on the Australian S&P200 Index. The class of models generalizes the traditional Black‐Scholes framework by accommodating time‐varying conditional volatility, skewness and excess kurtosis in the underlying returns process. An important property of these more general pricing models is that the computational requirements are essentially the same as those associated with the Black‐Scholes model, with both methods being based on one‐dimensional integrals. Bayesian inferential methods are used to evaluate a range of models nested in the general framework, using observed market option prices. The evaluation is based on posterior parameter distributions, as well as posterior model probabilities. Various fit and predictive measures, plus implied volatility graphs, are also used to rank the alternative models. The empirical results provide evidence that time‐varying volatility, leptokurtosis and a small degree of negative skewness are priced in Australian stock market options.     

An Eight-Step Guide to Creating and Sustaining a Mentoring Program

Mentoring is an extremely valuable activity for both individuals and organizations. Mentoring within organizations can develop and integrate employees into their corporate culture. Mentoring outside the mentees’ work groups or through professional development organizations can give broader perspective and support, especially in times of transition. But mentoring programs require tremendous effort to start, organize, and maintain. Few last more than two years. This article provides a structured approach to starting and sustaining a successful program. The steps include understanding an organization’s particular needs, learning from small pilot programs, following up with mentoring pairs during a committed formal mentoring period, and evaluating results from each program’s cycle to learn and grow the program. Supplementary materials for this article are available online.     

Relationships Between Parental Attachment,Work and Family Roles,and Life Satisfaction

The purpose of this study was to examine the relationship between parental attachment and satisfaction with work and family roles, as well as the relationship of these variables to life satisfaction. Results from a multiple regression analysis indicated that satisfaction with work and marriage, but not parenting satisfaction or parental attachment, was significantly related to life satisfaction. Responses to open‐ended questions indicated that parental attachment relationships affected participants' career, marriage, parenting, and life satisfaction in varied and complex ways. Implications for counselors and directions for future research are discussed.
