A Comparative Analysis of Selected Characteristics of Intellectually Superior Female Students who Persisted and Those who did not Persist in an Advanced Placement Program

Description: This study was undertaken to make a comparative analysis of selected nonintellective characteristics of intellectually superior female students who persisted and those who did not persist in an Advanced Placement Program offering sequentially planned course offerings in mathematics and science. A second dimension of the study was an investigation of selected nonintellective traits to determine if the students' scores are elevated in the same direction as those of superior female adults who have been studied on essentially the same dimensions.

Physiological and Verbal Responses to Erotic Visual Stimuli in a Female Population

Description: In recent years, there has been a growing acceptance of sexual behavior as a legitimate area of research. An impetus for research utilizing erotic visual stimuli was supplied by the Presidential appointment of the Commission on Obscenity and Pornography (1963). Research into the effects of erotic visual stimuli has typically employed male subjects (Neiger, 1966). The paucity of adequate research has not been a deterrent to the formulation of strong opinions regarding the nature of female sexuality. The present research has focused on female responses to visual representations of the nude male figure.

Self-selection contributes significantly to the lower adiposity offaster, longer-distanced, male and female walkers

Description: Although cross-sectional studies show active individuals areleaner than their sedentary counterparts, it remains to be determined towhat extent this is due to initially leaner men and women choosing toexercise longer and more intensely (self-selection bias). In this reportwalking volume (weekly distance) and intensity (speed) were compared tocurrent BMI (BMIcurrent) and BMI at the start of walking (BMIstarting) in20,353 women and 5,174 men who had walked regularly for exercise for 7.2and 10.6 years,respectively. The relationships of BMIcurrent andBMIstarting with distance and intensity were nonlinear (convex). Onaverage, BMIstarting explained>70 percent of the association betweenBMIcurrent and intensity, and 40 percent and 17 percent of theassociation between BMIcurrent and distance in women and men,respectively. Although the declines in BMIcurrent with distance andintensity were greater among fatter than leaner individuals, the portionsattributable to BMIstarting remained relatively constant regardless offatness. Thus self-selection bias accounts for most of the decline in BMIwith walking intensity and smaller albeit significant proportions of thedecline with distance. This demonstration of self-selection is germane toother cross-sectional comparisons in epidemiological research, givenself-selection is unlikely to be limited to weight or peculiar tophysical activity.

Outrunning major weight gain: a prospective study of 8,340consistent runners during 7 years of follow-up

Description: Background: Body weight increases with aging. Short-term,longitudinal exercise training studies suggest that increasing exerciseproduces acute weight loss, but it is not clear if the maintenance oflong-term, vigorous exercise attenuates age-related weight gain inproportion to the exercise dose. Methods: Prospective study of 6,119 maleand 2,221 female runners whose running distance changed less than 5 km/wkbetween their baseline and follow-up survey 7 years later. Results: Onaverage, men who ran modest (0-24 km/wk), intermediate (24-48 km/wk) orprolonged distances (>_48 km/wk) all gained weight throughage 64,however, those who ran ?48 km/wk had one-half the average annual weightgain of those who ran<24 km/wk. Age-related weight gain, and itsreduction by running, were both greater in younger than older men. Incontrast, men s gain in waist circumference with age, and its reductionby running, were the same in older and younger men. Women increased theirbody weight and waist and hip circumferences over time, regardless ofage, which was also reduced in proportion to running distance. In bothsexes, running did not attenuate weight gain uniformly, but ratherdisproportionately prevented more extreme increases. Conclusion: Men andwomen who remain vigorously active gain less weight as they age and thereduction is in proportion to the exercise dose.

Hispanic Women Leaders in K&#8210;12 Public Education: Overcoming Barriers to Success

Description: Scholarly research has been written on the forces behind the barriers preventing Hispanic women from reaching the top of the public school ladder. These barriers are to be recognized and addressed. This study focuses not on the barriers which hinder forward and upward career movement, but instead examines how many Hispanic American women have not allowed these barriers to prevent them from achieving their goals of attaining the principalship. This study seeks to determine how Hispanic women principals came to grips with the challenges and barriers to promotion, and to success as K&#8210;12 school leaders. This qualitative research study consisted of 12 Hispanic female school principals from the Dallas/Fort Worth metropolitan area. The three districts selected were Fort Worth Independent School District, Arlington Independent School District, and Grand Prairie Independent School District. Three principals were from Grand Prairie Independent School District, two principals were from Arlington Independent School District, and seven principals were from the Fort Worth Independent School District. All of the 12 Hispanic school principals were interviewed. From the responses to each of the questions, themes became evident. The themes expressed what individual principals had done and the strategies they used to overcome the varied barriers which they confronted. The responses to the interview questions and the themes were very insightful and displayed the women's tenacity, courage, perseverance, and determination to succeed in their aspirations to become Hispanic female principals and leaders in their school districts.

Why even active people get fatter--the asymmetric effects ofincreasing and decreasing exercise

Description: Background: Public health policies for preventing obesityneed guidelines for active individuals who are at risk due to exerciserecidivism. Methods: Changes in adiposity were compared to the runningdistances at baseline and follow-up in men and women whose reportedexercise increased (N=4,632 and 1,953, respectively) or decreased (17,280and 5,970, respectively) during 7.7 years of follow-up. Results: PerDelta km/wk, decreases in running distance caused over four-fold greaterweight gain between 0-8 km/wk (slope+-SE, males: -0.068+ -0.005 kg/m2,females: -0.080+-0.01 kg/m2) than between 32-48 km/wk (-0.017+-0.002 and-0.010+-0.005 kg/m2, respectively). In contrast, increases in runningdistance produced the smallest weight losses between 0-8 km/wk andstatistically significant weight loss only above 16 km/wk in males and 32km/wk in females. Above 32 km/wk (30 kcal/kg) in men and 16 km/wk (15kcal/kg) in women, weight loss from increasing exercise was equal to orgreater than weight gained with decreasing exercise, otherwise weightgain exceeded weight loss. Substantial weight gain occurred in runnerswho quit running, which would be mostly retained with resumed activity.Conclusion: Public health recommendations should warn against the risksof irreversible weight gain with exercise cessation. Weight gained due toreductions in exercise below 30 kcal/kg in men and 15 kcal/kg in womenmay not be reversed by resuming prior activity. Current IOM guidelines(i.e., maintain total energy expenditure at 160 percent of basal) agreewith the men s exercise threshold for symmetric weight change withchanging exercise levels.

Ecological Analysis of Physical Activity and Health-related Quality of Life in Female College Students.

Description: Health-related quality of life (HRQOL) is a comprehensive construct including physical and psychosocial health functioning. Despite significant health benefits of regular physical activity (PA), over 40% of female college students do not meet recommended PA guidelines to improve their health. This study investigated the influences of individual, social, and physical environmental factors on students’ PA and HRQOL. Participants were 235 female university students who completed validated surveys assessing their perceptions of PA, HRQOL, and social ecological factors. Three hierarchical regressions revealed individual and physical environmental factors as predictors of PA and HRQOL. These findings indicated health professionals need to consider students’ individual factors and physical environmental factors to promote female students’ PA and HRQOL.

The Effects of Mirror Confrontation on Body Image Ratings

Description: There are conflicting data in the literature regarding the effects of mirror exposure on subjective body-image evaluation. Much of the objective self-awareness research by Duval and Wicklund concluded that the presence of a mirror leads people to evaluate themselves negatively, while other studies have reported contrary findings. The primary purpose of this study was to determine the effects of mirror confrontation on individuals' body image ratings. Subjects were 88 childless, female university students. Using the Eating Disorders Inventory-Body Dissatisfaction subscale (BDS) as a screener, subjects were assigned to either a High Satisfaction group or a Low Satisfaction group. The subjects then completed the Multidimensional Body-Self Relations Questionnaire (MBSRQ) in either a Mirror or No Mirror condition. Results suggest that the presence of the mirror had no measurable effect on the subjects' ratings of themselves on the MBSRQ. There was a main effect for satisfaction level, and no interaction was found between the satisfaction level and the mirror condition. Possible explanations for these findings are offered.

Interactive effects of age and exercise on adiposity measures of41,582 physically active women

Description: The objective of this report is to assess in women whether exercise affects the estimated age-related increase in adiposity, and contrariwise, whether age affects the estimated exercise-related decrease in adiposity. Cross-sectional analyses of 64,911 female runners who provided data on their body mass index (97.6 percent), waist (91.1percent), and chest circumferences (77.9 percent). Age affected the relationships between vigorous exercise and adiposity. The decline in BMI per km/wk run was linear in 18-25 year olds (-0.023+-0.002 kg/m2 perkm run) and became increasingly nonlinear (convex or upwardly concave) with age. The waist, hip and chest circumferences declined significantly with running distance across all age groups, but the declines were 52-58 percent greater in older than younger women (P&lt;10-5). The relationships between body circumferences and running distance became increasingly convexity (upward concavity) in older women. Conversely, vigorous exercise diminished the apparent increase in adiposity with age. The rise in average BMI with age was greatest in women who ran less than 8 km/week (0.065+-0.005 kg/m2 per y), intermediate of women who ran 8-16km/wk (0.025+-0.004kg/m2 per y) or 16-32 km/wk (0.022+-0.003 kg/m2 pery), and least in those who averaged over 32 km/wk (0.017+-0.001 kg/m2 pery). Before age 45, waist circumference rose 0.055+-0.026 cm in for those who ran 0-8 km/wk, showed no significant change for those who ran 8-40km./wk, and declined -0.057+-0.012 and -0.069+-0.014 cm per year in those who ran 40 -56 and over 56 km/wk. The rise in hip and chest circumferences with age were significantly greater in women who ran under eight km/wk than longer distance runners for hip (0.231+-0.018 vs0.136+-0.004 cm/year) and chest circumferences (0.137+-0.013 vs0.053+-0.003 cm/year). These cross-sectional associations suggest that in women, age and vigorous exercise interact with each other in affecting adiposity. The extent that these cross-sectional associations are causally related to vigorous exercise or are ...

Partially redundant functions of two SET-domain polycomb-group proteins in controlling initiation of seed development in Arabidopsis

Description: In Arabidopsis, a complex of Polycomb-group (PcG) proteins functions in the female gametophyte to control the initiation of seed development. Mutations in the PcG genes, including MEDEA (MEA) and FERTILIZATION-INDEPENDENT SEED 2 (FIS2), produce autonomous seeds where endosperm proliferation occurs in the absence of fertilization. By using a yeast two-hybrid screen, we identified MEA and a related protein, SWINGER (SWN), as SET-domain partners of FIS2. Localization data indicated that all three proteins are present in the female gametophyte. Although single-mutant swn plants did not show any defects, swn mutations enhanced the mea mutant phenotype in producing autonomous seeds. Thus, MEA and SWN perform partially redundant functions in controlling the initiation of endosperm development before fertilization in Arabidopsis.

Group Activity Play Therapy for Preadolescents: Effects on Low Self-Esteem

Description: Research shows that preadolescent females are more prone to negative self-perceptions than their male counterparts which places them at greater risk of developing mental health problems stemming from low self-image. The purpose of this randomized, controlled outcome study was to examine the effectiveness of group activity play therapy (GAPT) compared to an evidenced based social skills/self-esteem group. Participants were 29 fourth and fifth grade girls in two Title I schools in the southwest U.S. referred by teachers and school counselors as presenting with low self-esteem. Participants identified as 45% Latina, 38% Caucasian, 14% African American, and 3% Asian. Children were randomly assigned to either 16 sessions of GAPT (experimental group; n = 15) or 13 sessions of an evidenced based social skills/self-esteem group intervention (control group; n = 14). Results from a 2 (Group) by 3 (Times) repeated measures ANOVA indicated that, compared to the control group over time, the GAPT group reported statistically significant improvement in self-esteem with a moderate to large treatment effect. Teachers did not report a statistically significant difference between the two groups over time. However, teachers reported noteworthy improvement for children in both treatment groups, with generally stronger improvement for the GAPT group. Overall, results indicate that GAPT may be a promising school-based intervention for preadolescent females suffering with low self-esteem.

Investigations into the Early Life-history of Naturally Produced Spring Chinook Salmon and Summer Steelhead in the Grande Ronde River Basin, Annual Report 2001.

Description: We determined migration timing and abundance of juvenile spring chinook salmon Oncorhynchus tshawytscha and juvenile steelhead/rainbow trout Oncorhynchus mykiss using rotary screw traps on four streams in the Grande Ronde River basin during the 2001 migratory year (MY 2001) from 1 July 2000 through 30 June 2001. Based on migration timing and abundance, two distinct life-history strategies of juvenile spring chinook and O. mykiss could be distinguished. An 'early' migrant group left upper rearing areas from 1 July 2000 through 29 January 2001 with a peak in the fall. A 'late' migrant group descended from upper rearing areas from 30 January 2001 through 30 June 2001 with a peak in the spring. The migrant population of juvenile spring chinook salmon in the upper Grande Ronde River in MY 2001 was very low in comparison to previous migratory years. We estimated 51 juvenile spring chinook migrated out of upper rearing areas with approximately 12% of the migrant population leaving as early migrants to overwinter downstream. In the same migratory year, we estimated 16,067 O. mykiss migrants left upper rearing areas with approximately 4% of these fish descending the upper Grande Ronde River as early migrants. At the Catherine Creek trap, we estimated 21,937 juvenile spring chinook migrants in MY 2001. Of these migrants, 87% left upper rearing areas early to overwinter downstream. We also estimated 20,586 O. mykiss migrants in Catherine Creek with 44% leaving upper rearing areas early to overwinter downstream. At the Lostine River trap, we estimated 13,610 juvenile spring chinook migrated out of upper rearing areas with approximately 77% migrating early. We estimated 16,690 O. mykiss migrated out of the Lostine River with approximately 46% descending the river as early migrants. At the Minam River trap, we estimated 28,209 juvenile spring chinook migrated out of the river with ...

Allele-specific deposition of macroH2A1 in Imprinting Control Regions

Description: In the current study, we analyzed the deposition patterns of macroH2A1 at a number of different genomic loci located in X chromosome and autosomes. MacroH2A1 is preferentially deposited at methylated CpG CpG-rich regions located close to promoters. The macroH2A1 deposition patterns at the methylated CpG islands of several imprinted domains, including the Imprinting Control Regions (ICRs) of Xist, Peg3, H19/Igf2 Igf2, Gtl2/Dlk1, and Gnas domains, show consistent allele-specificity towards inactive, methylated alleles. The macroH2A1 deposition levels at the ICRs and other Differentially Methylated Regions (DMRs) of these domains are also either higher or comparable to those observed at the inactive X chromosome of female mammals. Overall, our results indicate that besides DNA methylation macroH2A1 is another epigenetic component in the chromatin of ICRs displaying differential association with two parental alleles.

Residual Cognitive Functioning of Elderly Males

Description: The Aronson Cognitive Residual Evaluation Scale (ACRES), designed to assess residual cognitive functioning with potential loss due to age or CNS disorder, was examined with a male subject group. The five ACRES subtests were administered to 45 elderly males. Results were compared with a previously reported subject group of 48 elderly females. Measures of the subjects' levels of independent functioning and their performances on selected Wechsler Memory Scale Revised (WMS-R) subtests were related to ACRES scores. Intercorrelations among ACRES subtests suggest that more than one cognitive factor is assessed. WMS-R subtests showed moderately significant correlations with ACRES for verbal tasks and for nonverbal tasks. Findings were discussed within a framework of lateralization of CNS functions.

Normative Assessment Technique for Bench Press and Leg Extension Strength in College Females on the Universal Gym

Description: This study was to develop normative data of isotonic muscular strength in college females using the Spartacus model Universal Gym bench press and leg extension and to control for the influence of body weight. Two hundred and two college age females enrolled in weight training and conditioning classes used the Universal Gym for twelve weeks. Subjects were tested for maximum strength on 2 exercises and their percent body fat was calculated. Pearson-product moment correlations between lean body weight , body weight and the bench press test and the leg extension test were correlated. After statistically controlling for the effects of body weight, percentile ranks were calculated for both tests.

The pathogen transmission avoidance theory of sexual selection

Description: The current theory that sexual selection results from female preference for males with good genes suffers from several problems. An alternative explanation, the pathogen transmission avoidance hypothesis, argues that the primary function of showy traits is to provide a reliable signal of current disease status, so that sick individuals can be avoided during mating. This study shows that a significant risk of pathogen transmission occurs during mating and that showy traits are reliable indicators of current disease status. The origin of female choosiness is argued to lie in a general tendency to avoid sick individuals, even in the absence of showy traits, which originate as exaggerations of normal traits that are indicative of good health (bright feathers, vigorous movement, large size). Thus, in this new model the origins of both showy traits and female choosiness are not problematic and there is no threshold effect. This model predicts that when the possession of male showy traits does not help to reduce disease in the female, showy traits are unlikely to occur. This case corresponds to thorough exposure of every animal to all group pathogens, on average, in large groups. Such species are shown with a large data set on birds to be less likely to exhibit showy traits. The good-genes model does not make this prediction. The pathogen transmission avoidance model can also lead to the evolution of showy traits even when selection is not effective against a given pathogen (e.g., when there is no heritable variation for resistance), but can result in selection for resistance if such genes are present. Monogamy is argued to reduce selection pressures for showy traits; data show monogamous species to be both less parasitized and less showy. In the context of reduction of pathogen transmission rates in showy populations, selection pressure becomes inversely frequency-dependent, which ...

Independent Evaluation of The Lepestok Filtering Facepiece Respirator

Description: The purpose of this study was to determine the protection factor of the Lepestok-200 filtering facepiece respirator by conducting a standard quantitative fit test on a panel of 25 representative adults (14 males and 11 females) using the TSI Incorporated PortaCount PlusTM quantitative fit-testing system. Each subject was tested four times. In the total of 100 tests, 95% of the overall fit factors were greater than 3, more than 80% of the overall fit factors were greater than 14, approximately 50% were greater than 86, and 20% were greater than 200. The pass-fail performance of the respirator was similar for each of the six exercises in the test series: (1) normal breathing, (2) deep breathing, (3) moving the head side to side, (4) moving the head up and down, (5) reading a passage of text out loud, and (6) normal breathing, indicating that the respirator performs equally well for each type of exercise. A significant and sustained improvement in fit factor was observed after the initial test, indicating that the subjects benefited from the knowledge gained in the first of the four quantitative fit tests. In the 75 tests conducted after the initial test for each individual, 95% of the overall fit factors were greater than 6, more than 80% of the overall fit factors were greater than 23, and 50% were greater than 116, and 20% were greater than 200. Thus, the initial learning experienced doubled the fit factor for subsequent tests. In addition, there is an indication that the Lepestok-200 may perform better on wearers with wider faces than on individuals with narrower faces. The results of this study demonstrate the effectiveness of the Lepestok-200 respirator and reinforce the general conclusion that quantitative fit-testing can make an important contribution to ensuring that proper protection factors are achieved for ...

The iojap gene in maize

Description: The classical maize mutant iojap (Iodent japonica) has variegated green and white leaves. Green sectors have cells with normal chloroplasts whereas white sectors have cells where plastids fail to differentiate. These mutant plastids, when transmitted through the female gametophyte, do not recover in the presence of wild type Iojap. We cloned the Ij locus, and we have investigated the mechanism of epigenetic inheritance and phenotypic expression. More recently, a modifier of this type of variegation, ''Inhibitor of striate'', has also been cloned. Both the iojap and inhibitor of striate proteins have homologs in bacteria and are members of ancient conserved families found in multiple species. These tools can be used to address fundamental questions of inheritance and variegation associated with this classical conundrum of maize genetics. Since the work of Rhoades there has been considerable speculation concerning the nature of the Iojap gene product, the origin of leaf variegation and the mechanism behind the material inheritance of defective plastids. This has made Iojap a textbook paradigm for cytoplasmic inheritance and nuclear-organellar interaction for almost 50 years. Cloning of the Iojap gene in maize, and homologs in other plants and bacteria, provides a new means to address the origin of heteroplastidity, variegation and cytoplasmic inheritance in higher plants.
