Maintenance of skilled performance with age: a descriptive examination of professional golfers

Demographic studies indicate a remarkable aging trend in North America. An accurate profile of the decline in physical and cognitive capabilities over time is essential to our understanding of the aging process. This study examined the maintenance of skilled performance across the careers of 96 professional golfers. Data were collected on scoring average, driving distance, driving accuracy, greens in regulation, putts per round, and number of competitive rounds played using online data archives. Analyses indicate that performance in this activity can be maintained to a greater extent than in activities relying on biologically constrained abilities. Although the generalizability of these results to "normal" aging populations is not known, they suggest that acquired skills can be maintained to a large extent in the face of advancing age.     

Community Organization and Social Activism: Black Boston and the Antislavery Movement*

This paper uses data from an intensive study of Boston's antebellum black community to demonstrate how sustained social activism is embedded in the formal and informal institutions of the community. The social networks of cooperative institutions were primary factors in this community's ability to mobilize and sustain protest actions and to call attention to social injustice. This examination of antebellum black Boston indicates that the issue of slavery was crucial to social activism. This suggests that the presence of a salient issue which links the everyday lives of participants with a public issue may be an important factor in building a social movement based in a poor, relatively powerless community.     

Sport participation and positive development in older persons

In many Western countries, more and more people are living longer. As part of this demographic shift, increasing numbers are participating in Masters sport. In the past, sport was considered important for the development of young people; however, the potential for sport participation to affect positive development across the lifespan is now recognized. The purpose of this paper is to introduce conceptual frameworks from developmental psychology that are being used to understand youths’ positive development through sport, and to explore these frameworks in the context of sport as an avenue for positive development in older persons. To achieve this aim, we outline research on sport participation as it applies to youth development and consider relevant aspects as they broadly apply to development later in life. This discussion highlights the inherent paradox of sport participation—that it has the potential to provide considerable positive growth but also the potential for significant negative consequences. Finally, we explore areas of future research related to positive development in older persons through sport.     

The impact of school and college expenditures on the wages of southern and non-southern workers

Based on previous evidence of diminishing earnings returns to greater educational expenditures, the hypothesis that southern schools and colleges have greater returns than non-southern schools and colleges is tested but is not accepted. Per pupil expenditures for both school and college, however, significantly raise earnings for southern male full-time workers. The elasticity of expenditure with respect to the wage for high school graduates is 0.1212 for southerners and 0.0360 for non-southerners, and the elasticity for college expenditure is 0.0468 for southerners and 0.0260 for non-southerners. The author is grateful to Philip R. P. Coelho, W. Lee Hansen, Wayne H. Joerding, Victor J. Tremblay, and an anonymous referee for helpful suggestions and to the Mississippi Research and Development Center for support of this research.     

The relationship between explicit and implicit learning processes and probable pathological gambling

This paper reports the findings of a study of explicit and implicit learning and gambling with non-problem (n = 107), sub-clinical problem gamblers (n = 13), and probable pathological gamblers (n = 46). Two probability learning tasks modeled after gambling games and an artificial grammar task were used to explore how people learn patterns. In each of the two probability learning tasks, the outcome of the game was biased during the first part (learning phase) of the task. The results showed that many of the participants in the experimental conditions learned the bias and gradually unlearned the bias during the extinction phase of the study. Probable pathological gamblers showed less retention of the bias during two probability tasks and repeated the same errors during the artificial grammar task suggesting that they emphasize explicit learning strategies rather than implicit learning strategies. The results are consistent with the idea that pathological gamblers are more likely to utilize explicit rules than implicit rules.     

Violence Against the Young: The New Urban Challenges

This article examines the recent deaths of Chicago Public School students. It focuses on the school year between September 2006 and June 2007. At least 30 individuals were killed during that interval. In this school year, the homicides continue at about the same pace. Although violence within the schools had declined and violence (including homicides) was at a lower rate for the city of Chicago, some communities remained vulnerable to this threat. Neighborhood characteristics seem to be contributing factors, but family dynamics and an individual's life style comes into play. The person in the environment that we draw upon in social work has limitations, given new urban problems.     

Charismatic leadership: Eliciting and channeling follower emotions

Research on charismatic leadership has been criticized for the ambiguity of its central construct. Attempts to define and measure charisma have frequently treated it as a complex construct consisting of multiple components. However, little work has been done to develop a theoretical model that offers a parsimonious rationale explaining why certain leadership attributes are considered “charismatic” while others are not, or how these attributes combine to produce charismatic effects. Addressing these issues, we present a model that situates emotion as the primary variable in the charismatic process. We use recent research on the moral emotions to frame a theory of followership-relevant emotions (FREs) that describes how leaders use emotions such as compassion, admiration, and anger to compel their followers to act. We then discuss the Elicit-Channel (EC) model of charismatic leadership, positing that the charismatic relationship is a five-step, cyclical process. In the EC model, leaders elicit highly motivating emotions from their followers and then channel those emotions to produce action that, if successful, results in outcomes such as positive affect and trust. These outcomes then enable the leader to continue the cycle, eliciting emotion once more. We conclude by offering a research agenda, addressing potential methodological concerns, and discussing future directions.
