Explaining Gender Differences in the Perception of Support Availability: The Mediating Effects of Construct Availability and Accessibility

Perceived support availability (PSA), a general belief about the likelihood that social support will be available when needed, is associated with numerous processes and outcomes of supportive communication. Currently, however, there is little understanding of the factors that contribute to this belief. Numerous studies have reported gender differences in PSA, with women generally indicating that they see support as more available than do men; in turn, gender differences in PSA have been cited to explain gender differences in the production and interpretation of supportive messages. In an effort to explain gender differences in PSA and, more broadly, understand the social-cognitive factors that contribute to individual differences in PSA, this article proposes and reports a test of a theoretical model that treats PSA as the outcome of the availability and accessibility of cognitive schemata for construing social situations. Participants (150 men and 271 women) completed instruments providing assessments of PSA, construct availability (cognitive complexity), and construct accessibility (expressive and instrumental orientations). Bootstrap procedures for the simultaneous assessment of multiple mediators found that construct accessibility generally was a stronger mediator of gender differences in PSA than construct availability. However, a cooperative suppression effect was found for 1 index of construct accessibility, complicating the interpretation of mediation effects.     

Ancient Greek ‘Amateurism’, the NCAA and the Courts

The National Collegiate Athletic Association (NCAA) has recently been the target of many lawsuits challenging its definition and regulation of amateurism, which it holds as providing unique moral and social benefits for both its scholar-athletes and society at large. This conception of amateurism is inherited from nineteenth-century models of ancient Greek athletics via figures such as John Mahaffy and E.N. Gardiner. This influence is evident in legal cases involving the NCAA or athletics in general, and hence amateurism is cited by judges and others as a long-standing Western cultural tradition which encourages moral and social development. This is problematic, however, as not only is it historically questionable, but also the citation of cultural heritage in legal dicta has seen legal criticism or reversal.     

Analysis of accelerometer-derived interpersonal spatial proximities: A calibration,simulation, and validation study

The purpose of this study was to estimate distances from accelerometer-derived Bluetooth signals as a measure of interpersonal spatial proximity. Accelerometer-derived proximity data were collected indoors and outdoors over a 10m range to calibrate simulation models. Proximity data were simulated over 20m (indoor) and 50m (outdoor) ranges. Competing statistical and machine learning models were used to predict simulated distances; the Root-Mean-Square-Error (RMSE) was calculated. Simulation estimates were validated under conditions wherein a single beacon-receiver (SBR) and multiple beacons-receivers (MBR) collected proximity data indoors and outdoors within a ≤10m range. Simulation data showed that a Random Forest (RF) model performed optimally. The validated RF RMSE was ≤2.7 for SBR, and ≥90% of predicted distances were accurately classified as ≤10m. For MBR, ≥67% of predicted distances were accurately classified as ≤10m. Simulation and validation data suggest that distances can be estimated from accelerometer-derived proximity data within a 20m range using a SBR.     

Life events,self‐concept,and adolescents' positive subjective well‐being

This study investigated the interrelationships among global self‐concept, life events, and positive subjective well‐being (positive affect [PA], negative affect [NA], and life satisfaction [LS]) in a sample of 92 high school students. The results demonstrated that life events contributed significant variance to predictions of PA, NA, and LS, over and above that of global self‐concept. Also, daily events contributed variance over and above that of major life events. Looking at the specific event types that related uniquely to the positive well‐being measures, only negative daily events related significantly to PA and NA, and only positive daily events related significantly to LS. The results also indicated that the positive well‐being constructs each contained unique variance and had different correlates, thus providing strong support for the multidimensionality of adolescent positive well‐being reports. Implications for further research and intervention programs are discussed. © 2000 John Wiley & Sons, Inc.     

The use of Wechsler Scales in the assessment of Native Americans of the Columbia River Basin

Native American secondary students from the Columbia Basin were found to have significant Verbal-Performance discrepancies on the WISC-R and WAIS. Mean Verbal scores were significantly below the normative mean, while Performance scores were at, or above, the normative means. These findings substantiated research with other Native American groups. Also, the Verbal and Performance scales correlated so low as to preclude the Full Scale from being an accurate representation of the “g” factor of intelligence. Further, the predictive validity of the WISC-R and the WAIS for reading and math achievement was found to be at variance with the standardization group.     

Computers and medical information: an elective for fourth-year medical students

The Computers and Medical Information elective is a collaborative effort to expose students to a variety of computer applications for medical information management. The course has a modular format so that students can work with a variety of people who are enthusiastic users of computer-based information systems. The elective emphasizes learning by doing. Faculty introduce concepts and systems and serve as guides in the use of systems. Students have rated the course positively and, after four years as an elective, some of the course's content has been integrated into the required curriculum.     

Enhanced facial discrimination: effects of experience with American sign language

On-line comprehension of American Sign Language (ASL) requires rapid discrimination of linguistic facial expressions. We hypothesized that ASL signers' experience discriminating linguistic facial expressions might lead to enhanced performance for discriminating among different faces. Five experiments are reported that investigate signers' and non-signers' ability to discriminate human faces photographed under different conditions of orientation and lighting (the Benton Test of Facial Recognition). The results showed that deaf signers performed significantly better than hearing non-signers. Hearing native signers (born to deaf parents) also performed better than hearing nonsigners, suggesting that the enhanced performance of deaf signers is linked to experience with ASL rather than to auditory deprivation. Deaf signers who acquired ASL in early adulthood did not differ from native signers, which suggests that there is no 'critical period' during which signers must be exposed to ASL in order to exhibit enhanced face discrimination abilities. When the faces were inverted, signing and nonsigning groups did not differ in performance. This pattern of results suggests that experience with sign language affects mechanisms specific to face processing and does not produce a general enhancement of visual discrimination. Finally, a similar pattern of results was found with signing and nonsigning children, 6-9 years old. Overall, the results suggest that the brain mechanisms responsible for face processing are somewhat plastic and can be affected by experience. We discuss implications of these results for the relation between language and cognition.     

Faculty–library collaborations in digital history: A case study of the travel journal of Cornelius B. Gold

ABSTRACT

In this article, the authors present a case study on a teaching and learning initiative in digital humanities at Connecticut College. The article outlines a project in which students in a midlevel history course collaborated with library staff and faculty to develop a digital exhibition on a nineteenth-century journal in the College's collection. The cooperative approach and institutional support that the team received provided an effective and flexible means for achieving common goals. As students applied emergent technologies to college collections, they were able to conduct meaningful research and bring archival resources to new audiences.     

Cash incentives and turnover in center-based child care staff

The current study evaluates the Workforce INcentive Project (WIN), a programmatic effort to increase child care workforce stability in center- and home-based child care providers via the provision of bi-annual cash incentives based on educational attainment. Five hundred and thirteen center-based teaching staff (304 WIN and 209 comparison) and 167 center directors (93 WIN and 74 comparison) from 179 state-licensed child care centers (99 WIN and 80 comparison) participated in the study reported. Survival analyses were conducted to compare turnover rates between the WIN group and the comparison group over a 20-month period. All analyses controlled for participant satisfaction with employment, location (i.e., urban, suburban, and rural), and, where appropriate, hourly wages. Although WIN participation was generally associated with lower rates of turnover in center-based staff, when position type, educational attainment, experience in the field, and hourly wages were considered (separately and together), WIN's relationship with turnover varied widely for directors and teaching staff. Findings are discussed in terms of past research and future cash incentive programs.
