The Relationship Between Athletic Identity and Career Decisions in Athletes

The present study examined the association between athletic identity, career decision-making self-efficacy, future time attitude, gender, and age to explore the process of future career selection in athletes. The sample was composed of 153 athletes, and variables were measured using the Athletic Identity Measurement Scale–plus, the Career-Decision-Making Self-Efficacy Scale–Short Form, and the Time Attitude Scale. Results show that athletes with higher athletic identity have higher levels of career-decision-making self-efficacy and higher levels of optimism regarding the future. Furthermore, athletes with higher athletic identity are more likely intend to choose a sport-related profession in the future.     

Item Selection for the Development of Short Forms of Scales Using an Ant Colony Optimization Algorithm

This article presents the use of an ant colony optimization (ACO) algorithm for the development of short forms of scales. An example 22-item short form is developed for the Diabetes-39 scale, a quality-of-life scale for diabetes patients, using a sample of 265 diabetes patients. A simulation study comparing the performance of the ACO algorithm and traditionally used methods of item selection is also presented. It is shown that the ACO algorithm outperforms the largest factor loadings and maximum test information item selection methods. The results demonstrate the capabilities of using ACO for creating short-form scales.     

Illness representations,knowledge and motivation to perform presymptomatic testing for late-onset genetic diseases

This study addresses the relation between illness representations, knowledge and motivation to perform the presymptomatic testing (PST) of subjects at-risk for Familial Amyloydotic Polyneuropathy (FAP), Huntington’s disease (HD) and Machado–Joseph disease (MJD), compared with subjects at-risk for Hereditary Hemochromatosis (HH). The sample comprised a clinical group of 213 subjects at genetic risk for FAP, HD and MJD, and a comparison group of 31 subjects at genetic risk for HH, that answered three open-ended questions relating illness representations, knowledge about the disease, and motivation to perform PST. People at-risk for FAP, HD and MJD use more metaphors, make more references to the family, are more concerned with the future and feel more out of curiosity and to learn, than for HH. These subjects at-risk correspond to the profile of somatic individual or personhood, wherein the unsubjectivation of the disease can function as a coping mechanism.     

ON WILLIAMSON'S ARGUMENTS THAT KNOWLEDGE IS A MENTAL STATE

In Knowledge and Its Limits, Timothy Williamson argues that knowledge is a purely mental state, that is, that it is never a complex state or condition comprising mental factors and non‐mental, environmental factors. Three of his arguments are evaluated: arguments from (1) the non‐analyzability of the concept of knowledge, (2) the ‘primeness’ of knowledge, and (3) the (alleged) inability to satisfactorily specify the ‘internal’ element involved in knowledge. None of these arguments succeeds. Moreover, consideration of the third argument points the way to a cogent argument that knowledge is not a purely mental state.     

Longitudinal effects of human supremacy beliefs and vegetarianism threat on moral exclusion (vs. inclusion) of animals

Stronger beliefs in human supremacy over animals, and stronger perceived threat posed by vegetarianism to traditional practices, are associated with stronger speciesism and more meat consumption. Both variables might also be implicated in the moral exclusion of animals. We tested this potential in a 16-month longitudinal study in the USA (N = 219). Human supremacy showed longitudinal effects on the moral exclusion of all animals. Vegetarianism threat only predicted moral exclusion of food animals (e.g., cows and pigs), and, unexpectedly, appealing wild animals (e.g., chimps and dolphins). These findings demonstrate the importance of both human supremacy and perceived threat in explaining moral exclusion of animals and highlight potential paradoxical negative consequences of the rise of vegetarianism.     

The influence of competitive status (winner/loser) on the behavior of male rats in three models of anxiety

Studies indicate that features such as prior stressful experience, strain, gender, and age can influence the behavior of rats in animal models of anxiety. In the present study, we examined the possible influence of competitive status (winner/loser) in three such models: the elevated plus‐maze, the open field, and the social interaction test. One hundred to 135‐day‐old male Wistar rats were conditioned to traverse a straight runway tube to obtain food. Subsequently, two rats were placed at the same time in the runway tube and, being unable to pass each other, one of them pushed the other to the opposite end‐box. The rats were categorized as winners or losers in this competition. One week after the straight runway tube test, the rats were submitted to the anxiety models, where it was observed that winner rats showed greater locomotor activity than the losers in the three models studied. Furthermore, winner rats showed less immobility and higher central and total locomotor activity in the open field and a greater duration of social interaction in the social interaction test. These results suggest that competitive status has an influence on the locomotor activity of rats in animal models of anxiety. However, whether competitive status influences anxiety as assessed in these models is unclear, and further investigations are warranted. Aggr. Behav. 28:164–171, 2002. © 2002 Wiley‐Liss, Inc.
