The common space of personality traits and vocational interests

Investigated relationships between personality traits and vocational interests. Cattell's (Research and Consultations Center of Educational Personnel, 1976) CAQ Part I and the Ramak interest inventory (Meir, 1975) based upon Roe's (1956) occupational classification system were administered to a sample of 397 university applicants. Canonical Correlation Analysis and Smallest Space Analysis were used to test two hypotheses (a) relationships exist between personality traits and vocational interests; and (b) personality traits which characterize occupational profiles are arranged in circular order corresponding to the configuration Of the vocational fields which represent those occupations. Both hypotheses were supported by the data.     

Treatment of menopause-related mood disturbances

More than 1.7 million American women are expected to reach menopause each year. Recent Canadian statistics show that a 50-year-old woman can now expect to live until her mid-80s, which implies living at least one-third of her life after menopause. The menopausal transition is typically marked by intense hormonal fluctuations, accompanied by vasomotor symptoms (eg, hot flashes, night sweats), sleeps disturbance, and changes in sexual function, as well as increased risk for osteoporosis, cardiovascular disease, and cognitive decline. More importantly, recent studies have demonstrated a significant association between menopausal transition and a higher risk for developing depression. In the post-Women's Health Initiative Study era, physicians and patients are questioning the safety and efficacy of long-term hormone therapy use. This article reviews the current literature on the benefits and risks of using hormone therapy for the treatment of menopause-related mood disturbances and alternate strategies currently available for the management of menopause-related problems, including antidepressants, complementary and alternative medicine, and selective estrogen receptor modulators.     

Mental and Motor Switching in Parkinson's Disease

Switching difficulties in Parkinson's disease (PD) are expressed in both mental and motor tasks. The authors of the present study investigated whether those deficits coexist in the same patient and are positively correlated. They tested 8 nondemented PD patients and 6 age-matched control participants by using the modified Wisconsin Card Sorting Test and a motor switching paradigm that is based on the task of reaching toward visual targets, the location of which could unexpectedly be altered within the reaction time. In both mental and motor tasks, patients performed significantly worse than controls. There were no significant correlations between the two types of pathology in individual patients. Mental and motor switching deteriorate in PD patients, but the deficits are not necessarily of parallel severity.

Rate it again: Using the wisdom of many to improve performance evaluations

Much research shows that judgmental estimation could be improved by combining estimates from independent judges as well as within judges. These results have been obtained mostly with judgments about matters of fact, that is, for which there are objective truth criteria. In the present research, we extend these findings to performance evaluations. In a controlled field study, expert judges provided evaluations of a large number of essays written by college applicants taking college entrance tests. The judges were asked to evaluate each essay twice—on two occasions, a week apart. This design allowed us to assess the benefits of two methods of combining evaluations: within rater and across raters. Accuracy gains were obtained with both methods. Although the within‐rater combinations yielded fewer gains than the across‐rater ones, they were still appreciable in comparison with the across rater ones. Our findings extend the class of judgments to which the “wisdom of many” could be applied. These findings are potentially applicable to performance evaluations in social, educational, and employment settings.     

The attitude toward mamzerim in Jewish society in late antiquity

The purpose of this paper is to analyze the attitude of the Jewish people to a marginal group in that society: mamzerim, from Biblical times to Late Antiquity. The social exclusion of mamzerim is already stated in Deutoronomy 23:3, though a reading of several later rabbinic and non-rabbinic sources suggests how this exclusion really took place. It is assumed that mamzerim were not accepted into the Qumram sect, just like handicapped persons, and they were not allowed to enter the Temple. According to rabbinic law a mamzer was excluded from society (as his parents' punishment), by the prohibition of marrying anyone of distinguished genealogy. However, there are sources that testify that prior to the crystallization of rabbinic law (in the second century c.e.) there were other ways of denying mamzerim access to society: they were prohibited from entering the Temple, they were not taught Torah, a mamzer's house and grave were painted white to point him out. According to a source in Toldot Yeshu, mamzerim were shaved bald so they were set apart from the community in many aspects of daily life. Analyzing the sources leads to an historical understanding of social exclusion as practiced in Jewish society in the past. It is argued that the `normative' rabbinic law testifies to a process of limiting the expulsion of mamzerim from society. It seems that this process reflects the new modes of life (especially after the destruction of the Temple), that the society had to face: a change in the family structure on the one hand, and relatively numerous mamzerim on the other hand. This revised version was published online in August 2006 with corrections to the Cover Date.     

Reaching within video-capture virtual reality: using virtual reality as a motor control paradigm.

We have developed a virtual reality (VR) system that integrates a three-dimensional tracking device with a video-capture VR platform to record upper limb movements. The influence of target velocity on planning and execution of reaching movements was studied in five healthy subjects. Our initial results suggest that a target's velocity is considered when planning an interceptive action and that a hand reaching toward a moving virtual target is controlled in a similar way to how it is in the real visual environment.
