Self-Consciousness and Body Image Issues Among College Females

This study examined some of the procedures used in eating disorder research. Body size estimation procedures, in light of their similarity to procedures in social psychology, were used to create self-focus and self-consciousness conditions. If the procedures in the present study create self-consciousness effects, it is possible that the results of those studies have been affected by a heightened state of self-awareness. The present research also explored the relationships between self-consciousness, self-esteem, body esteem, body perception, and eating disorder proneness. The research was conducted with a nonclinical sample from a university population, controlling for age and body development factors. Baseline and experimental measures of objective self-awareness and body size perception were taken. The experimental conditions consisted of the presence of a) a VCR and mirror and b) an observer who was rating the subject. The third condition was a control setting that replicated the baseline setting. The sample was also tested at the posttest for self-esteem, body esteem, and eating disorder proneness. The results indicate that the subjects reported no significant changes in self-consciousness or body size estimates, suggesting that something besides the presence of equipment influences whether or not one feels selfconscious. This idea has been borne out in other research that implicates self-esteem as a major consideration in whether or not an individual feels self-conscious in certain situations (that is, that low self-esteem appears to increase one\u27s amenability to induce self-consciousness). Another primary factor is that self-consciousness cannot be induced when the individual is interested in the task. Subjects in the present study indicated that they found the tasks inherently interesting and forgot about the presence of equipment and observers once they began thinking about the questions posed to them. In the present research, selfesteem and body esteem were both found to be negatively related to self-consciousness, while eating disorder proneness was found to be positively related to selfconsciousness. The results are discussed in light of these connections, and suggestions for future research are provided

Principles of Glomerular Organization in the Human Olfactory Bulb – Implications for Odor Processing

Olfactory sensory neurons (OSN) in mice express only 1 of a possible 1,100 odor receptors (OR) and axons from OSNs expressing the same odor receptor converge into ∼2 of the 1,800 glomeruli in each olfactory bulb (OB) in mice; this yields a convergence ratio that approximates 2∶1, 2 glomeruli/OR. Because humans express only 350 intact ORs, we examined human OBs to determine if the glomerular convergence ratio of 2∶1 established in mice was applicable to humans. Unexpectedly, the average number of human OB glomeruli is >5,500 yielding a convergence ratio of ∼16∶1. The data suggest that the initial coding of odor information in the human OB may differ from the models developed for rodents and that recruitment of additional glomeruli for subpopulations of ORs may contribute to more robust odor representation

The James Webb Space Telescope Mission

Twenty-six years ago a small committee report, building on earlier studies, expounded a compelling and poetic vision for the future of astronomy, calling for an infrared-optimized space telescope with an aperture of at least $4m$. With the support of their governments in the US, Europe, and Canada, 20,000 people realized that vision as the $6.5m$ James Webb Space Telescope. A generation of astronomers will celebrate their accomplishments for the life of the mission, potentially as long as 20 years, and beyond. This report and the scientific discoveries that follow are extended thank-you notes to the 20,000 team members. The telescope is working perfectly, with much better image quality than expected. In this and accompanying papers, we give a brief history, describe the observatory, outline its objectives and current observing program, and discuss the inventions and people who made it possible. We cite detailed reports on the design and the measured performance on orbit.Comment: Accepted by PASP for the special issue on The James Webb Space Telescope Overview, 29 pages, 4 figure

Instructional Models for Course-Based Research Experience (CRE) Teaching

The course-based research experience (CRE) with its documented educational benefits is increasingly being implemented in science, technology, engineering, and mathematics education. This article reports on a study that was done over a period of 3 years to explicate the instructional processes involved in teaching an undergraduate CRE. One hundred and two instructors from the established and large multi-institutional SEA-PHAGES program were surveyed for their understanding of the aims and practices of CRE teaching. This was followed by large-scale feedback sessions with the cohort of instructors at the annual SEA Faculty Meeting and subsequently with a small focus group of expert CRE instructors. Using a qualitative content analysis approach, the survey data were analyzed for the aims of inquiry instruction and pedagogical practices used to achieve these goals. The results characterize CRE inquiry teaching as involving three instructional models: 1) being a scientist and generating data; 2) teaching procedural knowledge; and 3) fostering project ownership. Each of these models is explicated and visualized in terms of the specific pedagogical practices and their relationships. The models present a complex picture of the ways in which CRE instruction is conducted on a daily basis and can inform instructors and institutions new to CRE teaching

Predictors of Decreased Self-Care among Spouse Caregivers of Older Adults with Dementing Illnesses

This study describes the health behaviors (alcohol consumption, exercise, sleep patterns, smoking, and weight maintenance) of a sample of older adult spouse caregivers (N = 233) and investigates the predictors of decreased self-care since caregiving began. Multiple regression results indicate that caregivers who experience greater developmental burden, report a greater number of depressive symptoms, perform a greater number of activities of daily living (ADL) tasks in caregiving and spend more hours in a day providing care, and who have lower self-efficacy for both self-care and spouse care are at greater risk for negative health behavior change. Results have implications for the identification of caregivers who may be particularly vulnerable to the negative health impact of caregiving.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/68016/2/10.1177_089826439700900306.pd

The Stress Process among Dementia Spouse Caregivers

This study examines the relationship between the demands of providing care to a spouse with dementia and caregiver health behaviors, specifically exercise, sleep patterns, weight maintenance, smoking, and alcohol consumption. Structural equation modeling was used to test a model predicting health behavior change from personal and environmental characteristics, perceived stress, social support, and depressive symptoms in a sample of 233 spouse caregivers of dementia patients and to examine gender differences in these relationships. Results support the hypothesis that caregiving negatively influences health behaviors. Among both women and men, health behavior change is directly influenced by depressive symptoms and objective burden. In addition, depressive symptoms mediate the effects of self-efficacy and objective burden on health behavior change. These results support the notion that health behavior change may represent one mechanism by which caregiving stress leads to adverse health outcomes.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/68580/2/10.1177_0164027598203001.pd
