In this study, the authors examine Major League Baseball free agency to identify whether certain factors beyond a player’s on-field performance contribute to contract premiums. These premiums are considered to be the difference between the compensation a player receives in free agency and the marginal revenue product (MRPt-1) in their contract year. Using 345 free agent transactions over a four-year period (2012–2015), the authors examine the relationships between potential free agent contract premiums and the attributes of a player’s previous team, as well as how contract premiums may be influenced by the level of interest from other teams and certain facets of the acquiring teams. Results suggest that free agents tend to receive compensation premiums when they played for a successful team during their contract year. Playing for a large-market team during their contract year also influenced contract premiums. In addition, free agents tended to realize compensations premiums when multiple teams were bidding for their services, the acquiring teams were in playoff contention the prior year, and the acquiring teams possessed relatively more financial resources. Findings shed additional light on how factors peripheral to a player’s on-field performance may influence the free agency market. Recommendations include that effective control mechanisms are necessary to ensure free agent compensation is commensurate with the value of the player. 相似文献

This study investigated the influence of external load training (ELT) on static and dynamic balance. Nineteen females stratified into two groups (ELT = 9, control = 10) completed three testing sessions over 6 weeks. The ELT group wore weighted vests (WV) of ~8% body mass for 32 h/week during daily living and three training sessions/week for 3 weeks. Following completion of ELT, a 3 week detraining (DET) phase was completed. Bilateral and unilateral static balance were assessed with eyes open and closed. Dynamic balance was assessed using the star excursion balance test (SEBT). Static and dynamic balance variables were analysed using a 2 (group) x 3 (time) between participants repeated measures ANOVA (p < 0.05). Results revealed significant reductions in average centre of pressure (COP) velocity in the control group on the non-dominant limb with eyes closed, and significantly greater reach distances in the ELT group on the SEBT for the posteromedial and medial directions on the dominant limb (p < 0.05). These findings suggest the ELT group did not significantly improve their balance in comparison to the control group. However, future research should further examine this unique, supplemental training method and the impact on balance performance. 相似文献

Two experiments investigated the effects of a single reminder trial on immediate and delayed retention. Experiment 1 determined if beneficial effects of a reminder trial were a function of task order immediate retention performance benefited only when the reminder trial was practiced in the first block of trials. Experiment 2 added a 24-hr delayed retention test to examine the long-term benefits of a reminder trial. Retention performance was enhanced over both delay intervals. The long-term effect extended previous research (Shea & Titzer, 1993) that documented effects after 10 min. The use of a single reminder trial established that intertask comparisons between multiple reminder trials were not a precondition for the reminder trial effect as postulated by Shea and Titzer. 相似文献

El análisis del movimiento de la Nueva Canción Chilena, de gran popularidad a fines de la década de los 60 y principios de los 70, puede guiarnos hacia la conexión entre temas políticos y culturales, al tiempo que ayuda a aclarar parte de la compleja narrativa de esta época. Por lo menos el enfoque de la política en la cultura, y viceversa, demuestra que esitía un nexo claro entre las ideas políticas y económicas de los líderes de izquierda y de los artistas. En este artículo se hace precisamente el estudio de la narrativa de la Nueva Canción Chilena y su relación estrecha con el movimiento político de izquierda anterior a la elección de Salvador Allende. 相似文献

Although the HIV/AIDS epidemic began more than twenty years ago, there still is no cure for the disease and no vaccine to prevent infection. As with the general population, individuals with HIV/AIDS have sought care using a variety of traditional and nontraditional approaches. The popularity of complementary and alternative interventions among the HIV/AIDS community continues. To understand better the distribution of the HIV/AIDS body of knowledge concerning complementary and alternative medicine (CAM), this study sought to (1) examine the literature specific to the use of complementary and alternative medicine where HIV/AIDS is concerned to determine publication patterns; (2) determine the degree of overlap among bibliographic citation databases that index the literature concerning the use of CAM practices in treating HIV/AIDS; and (3) facilitate access to this body of literature. 相似文献
