The neuropsychological functioning of children and adolescents with anorexia nervosa

Chang, Jennifer 01 August 2018 (has links)
Researchers have suggested there is a wide range of neuropsychological deficits individuals with anorexia nervosa (AN) possess, including impairments in nonverbal reasoning, attention and processing speed, memory, and executive functioning. While growing, examination of the neuropsychological functioning of children and adolescents with AN is quite sparse compared to the abundance of research on adults with AN, and the many conflicting findings have been attributed to inconsistent methodologies across studies. This study examined the neuropsychological functioning of children and adolescents with AN by conducting a quantitative study loosely based on Bayless et al. (2002) and Remberk, Namysłowska, Krempa-Kowalewska, Gadaś, and Skalska (2011). Results indicated verbal intellectual functioning was significantly higher than other intellectual domains, and verbal memory was almost significantly higher than nonverbal memory (p = .051). Negative correlations were found between individual subtests and clinical data (e.g., age of onset of AN and duration of AN) as well as the EDI-3 Personal Alienation scale and the BMI-for-age percentile. Clinical implications include providing treatment improving cognitive functioning and implementing a biopsychosocial model.

Consumption of Iron-Fortified Cheese and Lipid Peroxidation in Females

Giunti, Gene J. 01 May 1994 (has links)
Dairy products are important sources of calcium and other nutrients but are a poor source of dietary iron. Cheese comprises a substantial portion of dairy food consumption and has been determined an appropriate medium for iron-fortification. However, iron may promote the potentially harmful process in food and biological systems known as lipid peroxidation. Therefore, the safety of consuming iron-fortified cheese was examined. Commercial-scale batches of Cheddar cheese were iron-fortified to a level of two milligrams of iron per ounce with either ferric chloride, ferric-casein complex, or ferric-whey protein complex. Fifty-four premenopausal females were divided into three treatment groups and supplemented one and one-half ounces of iron-fortified Cheddar cheese into their normal diet on a daily basis for six consecutive weeks. Lipid peroxidation was measured as thiobarbituric acid-reactive substances in serum, urine, and feces. A significant increase in serum thiobarbituric acid-reactive substances occurred in all treatment groups sixteen days after initiation of iron-fortified cheese consumption. Thiobarbituric acid-reactive substances in serum returned to baseline levels after thirty days of iron-fortified cheese consumption. Thiobarbituric acid-reactive substances in serum, urine, and feces did not differ among iron-fortification methods. Average daily intake of iron during the six weeks of iron-fortified cheese consumption significantly increased above baseline intake levels without cheese by the approximate amount of iron fortified into the cheese. Increased dietary iron intakes were not correlated with increased lipid peroxidation as measured by thiobarbituric acid-reactive substances in serum, urine, or feces. These results indicated that the daily consumption of iron-fortified cheese increased dietary iron intake and produced a transient increase in lipid peroxidation as measured by thiobarbituric acid-reactive substances in human serum.

Attitude and achievement of females in science : girls in single sex classes in the coeducational environment

Hayward, Ian, University of Western Sydney, Nepean, Faculty of Education January 1991 (has links)
There can be many influences affecting girls in secondary high schools which in turn produce many different outcomes on their progression through high school. The influences causing these effects are varied and in many instances interrelated, including those of peer pressure, self-perception and teacher influences. One possible outcome is that of the number of females selecting science at the senior secondary level being disproportionately low when compared to males. This thesis investigates one proposed method of increasing, the currently low, numbers of females selecting the physical sciences in Year 11 and Year 12 by examining attitudes and achievements of females when placed in a single sex class in a coeducational school. The results were unexpected when examined in light of the literature reviewed. Previous research predicted that females would benefit in attitude and achievement if removed from the mainstream coeducational classroom. The results of this study did not reflect this prediction. / Maser of Education

The Response of Elderly Female Fast Gait to Whole Body Vibration

Lorenzen, Hans Christian, res.cand@acu.edu.au January 2007 (has links)
Background: Older adults walk more slowly than healthy young adults at fast and normal walking speeds. These age-associated changes in mobility impact upon daily function. A slower gait, for example, may reduce the older adult’s ability to safely cross at traffic intersections due to the time restriction. Recent research has demonstrated whole body vibration (WBV) can improve the strength and power (Roelants, Delecluse & Verschueren, 2004; Russo et al., 2003; Verschueren, Roelants, Delecluse, Swinnen, Vanderschueren & Boonen, 2004) of community dwelling elderly females, and the mobility of nursing home residents (Bautmans, Van Hees, Lemper & Mets, 2005; Bruyere et al., 2005). To date, no published research has examined the impact WBV has on the gait parameters of community dwelling elderly females. The research was conducted in three phases. Phase One – Development of a WBV Platform: This phase outlines the development of a WBV platform (ACUWBV) that was designed and built for this research. A unique aspect of the ACUWBV was the method of adjusting WBV amplitude and therefore intensity. Current WBV technology, using tilting oscillations, requires the individual to increase their stance width. The ACUWBV allowed for the adjustment of WBV amplitude while maintaining the same stance width. The reliability and accuracy of the ACUWBV eccentric cam was measured during this phase of the research. Although an intraclass correlation coefficient of 0.4 was calculated and is considered an indication of low reliability, calculations of typical error (TE -95% error range) for each amplitude indicated the error to be small in the overall precision of the instrument. Specifically, at a frequency of 20 Hz, the expected WBV acceleration ranges for amplitudes of 0.5 mm and 1.0 mm were 7.58 m.s-2 to 8.85 m.s-2 (TE = 0.02 mm) and 16.90 m.s-2 to 17.53 m.s.-2 (TE = 0.01 mm), respectively. Phase Two – Pilot Study: This phase established the response of elderly community-dwelling female fast gait to WBV. Seven elderly female participants attended three WBV sessions per week for three weeks. Participants performed fast walks over an electronic walkway (GAITRite) at the end of each WBV session. A time-series graph displayed a linear increase in stride velocity over the three week intervention period. Conversely, stride time, stance time and double support time exhibited linear decreases. However, stride time (p=0.04) and stance time (p=0.04) were the only variables that exhibited a significant difference. It was concluded that the linear changes in stride velocity, stride time, stance time and double support time warranted further investigation with a larger sample size within a longer intervention period. Phase Three – Major Study: Phase three was an extension of phase two. This WBV intervention study was performed over a twelve week period. Twenty-two elderly female participants were placed in one of two groups. Group one (placebo/WBV; Group; n=12) was exposed to a placebo intervention for the first six weeks followed by a six week WBV intervention. Group two (Group WBV/placebo; n=10) was exposed to WBV for the first six weeks and a placebo intervention for the following six weeks. Group placebo/WBV exhibited no change in stride velocity during the placebo period, but a seven per cent increase during the six week WBV period (p=0.005). The changes in stride velocity coincided with increases in stride length (p=0.017), and reductions in stride time (p=0.007), stance time (p=0.001) and double support time (p=0.001). Group WBV/Placebo demonstrated stride velocity to increase by five per cent during the WBV period. Although the time-series graphs demonstrated improvements in stride velocity to be associated with decreases in stride time, stance time, and double support time, the changes failed to reach significance. Single support time and stride length showed no change over the WBV period. The improvements shown by group WBV/placebo from the first six weeks of WBV were maintained during the six week placebo (detraining) period. In summary, WBV was an effective intervention for enhancing the walking speed of community dwelling elderly female gait. This form of exercise may have positive outcomes on the daily function of elderly females, which in turn may improve their quality of life.

Women's subjective and objective health over time : the role of psychosocial conditions and physiological stress responses

Mellner, Christin January 2004 (has links)
Today, health problems are likely to have a complex and multifactorial etiology, whereby psychosocial factors interact with behaviour and bodily responses. Women generally report more health problems than men. The present thesis concerns the development of women’s health from a subjective and objective perspective, as related to psychosocial living conditions and physiological stress responses. Both cross-sectional and longitudinal studies were carried out on a representative sample of women. Data analysis was based on a holistic person-oriented approach as well as a variable approach. In Study I, the women’s self-reported symptoms and diseases as well as self-rated general health status were compared to physician-rated health problems and ratings of the general health of the women, based on medical examinations. The findings showed that physicians rated twice as many women as having poor health compared to the ratings of the women themselves. Moreover, the symptom ”a sense of powerlessness” had the highest predictive power for self-rated general health. Study II investigated individual and structural stability in symptom profiles between adolescence and middle-age as related to pubertal timing. There was individual stability in symptom reporting for nearly thirty years, although the effect of pubertal timing on symptom reporting did not extend into middle-age. Study III explored the longitudinal and current influence of socioeconomic and psychosocial factors on women’s self-reported health. Contemporary factors such as job strain, low income, financial worries, and double exposure in terms of high job strain and heavy domestic responsibilities increased the risk for poor self-reported health in middle-aged women. In Study IV, the association between self-reported symptoms and physiological stress responses was investigated. Results revealed that higher levels of medically unexplained symptoms were related to higher levels of cortisol, cholesterol, and heart rate. The empirical findings are discussed in relation to existing models of stress and health, such as the demand-control model, the allostatic load model, the biopsychosocial model, and the multiple role hypothesis. It was concluded that women’s health problems could be reduced if their overall life circumstances were improved. The practical implications of this might include a redesign of the labour market giving women more influence and control over their lives, both at and away from work.

Female and Gender Leadership : Under Representation of Female Leaders

Akhtar, Mehreen January 2008 (has links)
When we talk about the females employment in different organization, it is till treated in different disciplines. There are some gaps linked to it which still need to be filled in order to give equal opportunities to females as well. Although, from the last few decades it is been said and noticed that the number of females are rising to the top which is a symbol of progressive social change. However, it is also been noticed that there is still gender inequality in top management positions which leads to under presentation of females in top management position. The society and the masculine man has developed some theories. Due to which, it is been said that female qualities do not contribute to the required management attributes. For instance, In order to have an executive role, a person must be more aggressive, competitive, more task oriented etc. but females always have the opposite qualities. For instance, interpersonal relations, emotional, collaborative etc. This paper is an effort that shows the obstacles that woman faces in order to reach top management positions. Moreover, I also tried to describe that the traditional leadership model is linked to the masculine stereotypes. Henceforth, I tried to explain that the new organizational culture requires also the feminine stereotypes (emotions, interpersonal relations, cooperation etc). So, one could say that the leadership is not just linked to the masculine stereotypes but it also requires more of feminine qualities as well. The empirical study involves the semi structured interviews from men and women on management positions and also general discussions with the public. Based on these interviews and discussions I tried to analyze if both male and female follow the gender stereotypes and if they have difference in leadership styles according to gender. Hence, companies should have a more diversity in their organization in order to have more flexibility in organizational culture.

Ung och stressad : En kvalitativ studie om unga tjejers upplevelser och hantering av skolans krav

Andersson, Nina, Blomberg, Helena January 2009 (has links)
A considerable number young of students are suffering from sociopsychological complaints. The psychological complaints emerge from differnt sources. Important factors for psychological well being are experiences of a satisfactory social network, efficient coping strategies and a supportive school climate. The aim of this study was to examine how young girls in the age of 16-18 years old experience and cope with demands from school. To fulfill the aim of this study we have five questions: What do the girls apprehend as a satisfactory/unsatisfactory working environment? How do the girls define stress? How do the girls cope with stress? What importance has leisure time? What importance has the social network?   The method we used for this study was qualitative and the material was collected through four focus groups. Fourteen girls were interviewed from four different school classes with different profiles. The theoretical framework used to analyze the findings consisted of the demand-control-model created by Karasek & Theorell, Antonovsky’s KASAM theory and Selyes GAS-theory.   Stress expressed by the girls in this study is described as an unbalance between workload and available time. The analysis shows that most of the girls in the study experience school as a demanding setting that create strain. Furthermore, the results indicate that experienced demands not only originate from school but also from the girls themselves and by comparison with classmates. A satisfactory school environment is described as possibilities to influence the school work and the structrue of courses. Also a good relationship with teachers as well as classmates where pointed out as important factors. Strategies the girls use to cope with stress and demands are structuration, priority and planning. Some of the girls also think that a positive attitude towards life, regular eating and sleeping are important factors in coping with stress. All the girls describs leisure time as significant.  Most girls practice sport activites but activities as playing instrument, watching movies and spending time with peers is also mentioned. All of the girls find their leisure time as of importance for them to relax and revive from the strain caused by school. However, some girls find it hard to fully relax during leisure activites and also think that time for leisure is too limited. The social network is aslo seen as an important instrument in coping with strain. Most of the girls in this study do talk to family or friends in times of hardship.

African American Urban Female Students' Perceptions of Social Factors Impacting Their Academic Achievement in One Public School District

Shelby-King, Rhonda Evette 2010 May 1900 (has links)
The purpose of this study was to investigate the impact of social factors affecting the academic achievement of secondary African American urban (AAU) female students in an urban school district. This study determined whether the AAU females in this study perceived the social factors in the literature review to impact their academic achievement, the relationship between those social factors and academic achievement, and the differences in academic achievement by socioeconomic status. One hundred fifty-eight (158) AAU female students from three high schools in one urban district located in southeast Texas participated in this study. A self-generated 51-item questionnaire (Students' Perceptions of Social Factors Affecting Academic Achievement in Urban Schools) was used to collect data for this study. There were three major results in the study. First, there were not any significant factors impacting the academic achievement of AAU females; secondly, AAU females did not perceive any social factors as significantly affecting their academic achievement; and finally, there were not any statistical differences between socioeconomic status and academic achievement. Specifically, the results did not reveal a difference between AAU 12th grade female students on free and reduced lunch and those not on free and reduced lunch in terms of academic performance.

The Impact of Genital Self-Image on Gynecological Exam Behaviors of College-Aged Women

DeMaria, Andrea Laine 2011 May 1900 (has links)
Human papillomavirus (HPV) affects at least half of all sexually active people, especially those aged 20-24 years. Gynecological exams are instrumental in cervical cancer prevention due to the early detection of abnormal cervical cells often caused by HPV. Despite the many benefits of gynecological exams, they continue to be underused. Women are often unaware of exam guidelines, procedures, and costs. The Theory of Planned Behavior (TPB) was used to predict and explain exam behaviors. A woman’s decision to seek gynecological care may be influenced by numerous factors, including: genital self-image, body image and sexual behaviors. The purpose of this study was to: 1) determine if the TPB explains and predicts exam behaviors, 2) assess if genital self-image, body image and sexual behaviors predict exam behaviors, and 3) evaluate the reliability and validity of data collected on the Female Genital Self-Image Scale (FGSIS) among a sample of female college students. The study included a convenience sample of 450 women enrolled in health-related courses at a large Southern university in the US. SEM analyses revealed gynecological exam intention was a successful predictor of exam behaviors: Χ2 (81, N = 450) = 258.49, p <> <> <> .001, RMSEA = 0.07, CFI = 0.96 and NFI = 0.95. The addition of genital self-image to the TPB model yielded similar fit indices; however, the TPB alone appears to be more predictive of exam behaviors. Predictive discriminant analysis (PDA) was used to indicate the predictor, or group of predictors, best suited to predict gynecological exam behavior. PDA results indicate the number of vaginal intercourse partners during the past 3-months was most predictive (hit rate = 68.2%). A CFA yielded a two-factor FGSIS model: Χ2 (12, N = 450) = 49.77, p <> .001, RMSEA = 0.08, CFI = 0.98 and NFI = 0.97. Reliability assessments indicated very good internal consistency for the entire scale (α = 0.89), for factor one (α = 0.86) and factor two (α = 0.82). Results have implications for the development of sexual health and women’s health programs targeting factors influencing gynecological exam behaviors. Specifically, scores on the FGSIS can establish relationships between genital self-image and exam behaviors of college women.

Study on Influence of Sexually Attractive PR Females on the Relation between Activity Participants and Consumption

Wu, Chi-Ming 26 July 2008 (has links)
In recent years, many sexually attractive PR females can be seen at every exhibition. They are top models, stars, adult video actresses, poster girls, show girls, etc. A lot of literatures have mentioned that females are frequently objectified and commercialized in order to satisfy the desire of males in a patriarchal and capitalistic society. Due to the changing trends, saleswomen reveal different appearances in various frameworks of exhibition. Sexually attractive females have become the key persons in the exhibition; their mission is not only to soften the atmosphere permeated by cold hard products, but also to attract visitors, engage in customer relations, and achieve the expected turnover. The study subjects were visitors at the 2007 Kaohsiung Computer Multimedia and Audio Exhibition. By answering the questionnaires their ¡§visiting purpose¡¨ and ¡§purchase intention¡¨ as well as the ¡§demographic statistic variables¡¨ were all investigated. All data were analyzed via: descriptive statistics, reliability factors, correlation and single-factor variation (one way ANOVA). The correlation and study assumptions can therefore be verified. The research results showed that there is a correlation among ¡§visiting purpose¡¨, ¡§purchase intention¡¨ and ¡§demographic statistic variables.¡¨ It proved that the sexually attractive females did not necessarily attract consumers with pure intentions to purchase their desired products, but they did attract consumers who love to ogle scantily clad females or who just want to spend their free time at the exhibition. The demographic statistic variables presented that those sexually attractive females did attract many students under the age of 25, and they were willing to change their purchase intention. Companies can refer to this research in planning their sales strategies and determine special promotions where sexually attractive PR females can be used to help hawk their products, so that the best benefits can be achieved. Keywords: exhibition, feminism, sexually attractive females, visiting purpose, purchase intention
