    2012-01-01

    The present dissertation addresses psychological influences on eating behavior. Understanding why people eat what they eat in everyday life, that is, motives for eating behavior, is crucial for the development of interventions to promote normal eating and to prevent eating disorders. Furthermore, enhancing knowledge about both, individual and situational factors facilitating (pull factors) or impeding (push factors) healthy eating is essential for the prevention and treatment of obesity and i...

    Objective: To investigate the influences of resources and food-related goals on the variety of food choice among older people. Design: A questionnaire-based survey in eight European countries: Poland, Portugal, United Kingdom, Germany, Sweden, Denmark, Italy and Spain. Subjects: Participants (n 3200) were above 65 years of age and living in their ownhomes. The samples were quota samples, eight groups of fifty in each country, based on gender, age and living circumstances, reflecting the diversity of each of the national populations based on education, income and urbanization of living environment. Results: Hierarchical multiple regression analysis showed that income, health status, access to a car and living arrangement affected the level of dietary variety. The perceived level of different food-related resources impacted the consumption of a varied diet over and above actual resource levels. Food-related goals contributed to variety of food intake that was not accounted for by the amount of material resources possessed or the social and other resources perceived to be possessed. Conclusions: Older people's variety of food intake depended on material resources (e.g. monthly income, access to a car, living arrangement, physical and mental health). However, in addition to these variables, the way older peopleperceived other resources, such as their level of appetite, their food knowledge, their perception of the distance to the shops, access to high-quality products, having better kitchen facilities, access to good service providers and support from friends and neighbours, all contributed to how varied a diet they ate.

    Full Text Available La razón por la que los niños tienen determinadas características en el consumo de alimentos es un tema que preocupa tanto a padres, como a profesionales e investigadores cercanos a esta área de estudio. Aquí se buscó comprender los factores que hoy día son reconocidos como influyentes en el consumo [...] de alimentos por parte de la población infantil. Para ello se revisó literatura científica publicada desde enero de 2002 hasta abril de 2013; la revisión se adelantó en las bases de datos: Scopus, Science Direct, Ebscohost y Redalyc. Se obtuvieron 57 documentos acordes a los criterios de inclusión definidos. Dicho ejercicio llevó a clasificar la información encontrada en condiciones individuales, características del entorno y estrategias frecuentes que pueden influir en el consumo. La revisión realizada permite concluir que hoy en día, más que hablar solo de consumo, la mirada se traslada al comportamiento alimentario. Esto incluye las características de los alimentos consumidos, lugares, experiencias, compañías, entre otros aspectos, que forman parte de un patrón de conducta alrededor de los alimentos. De esta manera, se evidencian campos de intervención e investigación en aspectos tales como conducta alimentaria por género, rasgos genéticos y estado nutricional; también se exploran creencias y experiencias alrededor de los alimentos, grupos sociales influyentes, características organolépticas de las preparaciones y estrategias de promoción que involucran mucho más que trasmitir conocimiento acerca de lo saludable, entre otros. Abstract in english Why children have certain characteristics in food consumption is a matter of concern to both parents, as professionals and researchers in their exercise near this age group. This paper aim is to understand factors and mechanisms influencing in the decision of food intake by children. Scientific lite [...] rature published was revised, from January 2002 to April 2013, in the databases: Scopus, Science Direct, Ebscohost and Redalyc. 57 papers were obtained with the inclusion criteria used. This exercise led to classify the information found in individual conditions, characteristics of the setting and common strategies that may influence food consumption. Today, more than just talk about consumption, the works attends the feeding behavior, which includes the characteristics of the food consumed, places, experiences, companies, among others, as part of a pattern of behavior around food. This led to identify areas of intervention and research such as eating behavior by gender, genetic characteristics and nutritional status. And, the beliefs and experiences around food, influential social groups, organoleptic characteristics of recipes and promotion strategies, involve much more than transmit knowledge about how to be healthy, among others.

    2009-01-01

    Poor eating habits are an important public health issue that has large health and economic implications. Many food preferences are established early, but because people make more and more independent eating decisions as they move through adolescence, the transition to independent living during the university days is an important event. To study the phenomenon of food selection, the heath belief model was applied to predict the likelihood of healthy eating among university students. Structural equation modeling was used to investigate the validity of the health belief model (HBM) among 194 students, followed by gender-based analyses. The data strongly supported the HBM. Social change campaign implications are discussed. PMID:19408181

    2013-12-01

    We review recent research on the effect of social context on food intake and food choice and assess the implications for nutritional interventions. We focus on studies of modelling of eating behaviour and the impact of perceived eating norms on the amounts and types of food that individuals eat. We suggest that social context influences eating via multiple mechanisms, including identity signalling and self-presentation concerns. However, building on existing theoretical models, we propose that social factors may be particularly influential on nutrition because following the behaviour of others is adaptive and social norms inform individuals about behaviours that are likely to be optimal ('if everyone else is doing it, I probably should be'). Guided by understanding of the potential underlying mechanisms, we discuss how social norms might be used to promote healthier nutrition. PMID:24103526

  10. Social norms and their influence on eating behaviours.

    Science.gov (United States)

    Higgs, Suzanne

    2015-03-01

    Social norms are implicit codes of conduct that provide a guide to appropriate action. There is ample evidence that social norms about eating have a powerful effect on both food choice and amounts consumed. This review explores the reasons why people follow social eating norms and the factors that moderate norm following. It is proposed that eating norms are followed because they provide information about safe foods and facilitate food sharing. Norms are a powerful influence on behaviour because following (or not following) norms is associated with social judgements. Norm following is more likely when there is uncertainty about what constitutes correct behaviour and when there is greater shared identity with the norm referent group. Social norms may affect food choice and intake by altering self-perceptions and/or by altering the sensory/hedonic evaluation of foods. The same neural systems that mediate the rewarding effects of food itself are likely to reinforce the following of eating norms. PMID:25451578

    Despite many studies on the prevalence of breakfast eating, we know little about factors that determine breakfast eating patterns. Our aim was to find out to which extent breakfast eating frequency is influenced by genetic and environmental factors using twin and twin-family models in a population sample of 16-year-old twins (n = 5250) and their parents (n = 4663). In common effects sex-limitation models, additive genetic effects explained 41% (95% CI: 21-63%) of the variance in breakfast eating in girls and 66% (95% CI: 47-79%) in boys, and common environmental effects 45% (95% CI: 23-62%) in girls and 14% (95% CI: 5-29%) in boys. Of twin-family models, phenotypic assortment models fitted the data best. Heritability estimates increased somewhat (72%, 95% CI: 46-98% in girls and 63%, 95% CI: 38-89%) in boys. Common family environment remained substantial in both sexes. Cultural transmission was nonsignificant. The relative influence of genetic and family factors on adolescent breakfast eating frequency differs by sex and is generation-specific. PMID:15319573

    This study sought to examine risk and onset patterns in anorexia nervosa (AN), bulimia nervosa (BN), and binge eating disorder (BED). Women with AN (n=71), BN (n=66), BED (n=160) and non-psychiatric controls (n=323) were compared retrospectively on risk factors, symptom onset, and diagnostic migration. Eating disorder groups reported greater risk exposure than non-psychiatric controls. AN and BED differed on premorbid personality/behavioral problems, childhood obesity, and family overeating. Risk factors for BN were shared with AN and BED. Dieting was the most common onset symptom in AN, whereas binge eating was most common in BN and BED. Migration between AN and BED was rare, but more frequent between AN and BN and between BN and BED. AN and BED have distinct risk factors and onset patterns, while BN shares similar risk factors and onset patterns with both AN and BED. Results should inform future classification schemes and prevention programs. PMID:25103674

    We explored sex ratio at birth, defined as the proportion of male live births, in women with anorexia nervosa, bulimia nervosa, binge eating disorder, and eating disorders not otherwise specified-purging type (EDNOS-P) relative to a referent group in a large population-based sample of 38,340 pregnant women in Norway. Poisson regressions were adjusted for mother's age, pre-pregnancy BMI, lifetime smoking status, maternal education, income, marital status, gestational age, and parity. Lower proportions of male live births were observed in the anorexia and bulimia groups, while binge eating disorder and EDNOS-P were associated with a higher proportion of male births. These data suggest that maternal eating disorders may influence offspring sex and that the direction of effect may vary by eating disorder subtype. If confirmed, this finding could provide evidence in formulating hypotheses regarding the consequences of eating disorders and determinants of sex ratio at birth. PMID:18720046

  2. Contextual influences on eating behaviours: heuristic processing and dietary choices.

    Science.gov (United States)

    Cohen, D A; Babey, S H

    2012-09-01

    This paper reviews some of the evidence that dietary behaviours are, in large part, the consequence of automatic responses to contextual food cues, many of which lead to increased caloric consumption and poor dietary choices. We describe studies that illustrate how these automatic mechanisms underlie eating behaviours, as well as evidence that individuals are subject to inherent cognitive limitations, and mostly lack the capacity to consistently recognize, ignore or resist contextual cues that encourage eating. Restaurants and grocery stores are the primary settings from which people obtain food. These settings are often designed to maximize sales of food by strategically placing and promoting items to encourage impulse purchases. Although a great deal of marketing research is proprietary, this paper describes some of the published studies that indicate that changes in superficial characteristics of food products, including packaging and portion sizes, design, salience, health claims and labelling, strongly influence food choices and consumption in ways for which people generally lack insight. We discuss whether contextual influences might be considered environmental risk factors from which individuals may need the kinds of protections that fall under the mission of public health.

    2013-12-01

    This study investigated whether any of seven factors of family dysfunction predicted five risk factors for developing eating disorders in young adult women. Participants completed demographic questions, the McMaster Family Assessment Device (Epstein, Baldwin, & Bishop, 1983) and the Setting Conditions for Anorexia Nervosa Scale (Slade & Dewey, 1986) online. Five stepwise multiple regressions evaluated whether FAD scores predicted any of the eating disorder risk factors. Unhealthy affective responsiveness predicted general dissatisfaction and social and personal anxiety, and unhealthy general functioning predicted adolescent problems. No FAD factors predicted perfectionism or weight control. These results confirm the importance of families' affective responsiveness and general functioning to the risk of developing eating disorders. However, the lack of relationship among problem-solving, communication, roles, affective involvement, or behavior control with any of the risk factors for eating disorders warrants further investigation.

Methods Subjects were 2 997 females, aged 17 to 20 years, who participated in a phase III human papillomavirus vaccination trial in Finland in 2004 – 2009. Self-administered questionnaires and weight and height measurements were used. The factor structure of the TFEQ-R18 was verified by factor analysis. Connections between measured eating behaviour and Body Mass Index (BMI were tested using analysis of variance. Results The original factor structure of the TFEQ-R18 was replicated: six of the eighteen items measured cognitive restraint, nine measured uncontrolled eating, and three measured emotional eating. On average, higher BMI was associated with higher levels of cognitive restraint (p Conclusion Structural validity of the TFEQ-R18 was good in this sample of young Finnish females with a varying range of body weights. Use of the instrument as a measure of eating behaviour was thus corroborated. Connections of restrained and emotional eating with BMI were in accordance with previous findings from young females.

    2012-02-01

    OBJECTIVE: EPICA is the first large-scale Irish study of a school-going population examining the impact of media influences on eating attitudes. METHOD: Students were screened using the EAT-26, EDI-III and a study-specific questionnaire. A sub-sample of parents\\' views was included. RESULTS: Three thousand and thirty-one students (mean age 14.74) and 56 parents enrolled. The majority (71.4%) of adolescents felt adversely affected by media portrayal of body weight and shape, with more than a quarter (25.6%) believing it to be \\'far too thin\\'. A significant correlation between media impact and high EAT scores (chi2 = 450.78, df = 2, p < 0.05) and EDI-III scores (chi2 = 387.51, df = 4, p < 0.05) was demonstrated. Parents also view media portrayal as too thin (94.7%), less than half are adversely affected by it (49.2%) but the majority (71.9%) believe their children to be. CONCLUSION: Media portrayal of body weight and shape is correlated with eating psychopathology and may affect adolescents more than adults. School psycho-educational programmes and media policies are urgently needed to minimise any detrimental effect.

    2015-04-01

    Studies linking executive function (EF) and overweight suggest that a broad range of executive functions might influence weight via obesity-related behaviors, such as particular eating styles. Currently, however, longitudinal studies investigating this assumption in children are rare. We hypothesized that lower hot and cool EF predicts a stronger increase in eating styles related to greater weight gain (food approach) and a weaker increase in eating styles related to less weight gain (food avoidance) over a 1-year period. Hot (delay of gratification, affective decision-making) and cool (attention shifting, inhibition, working memory updating) EF was assessed experimentally in a sample of 1657 elementary-school children (German school classes 1-3) at two time points, approximately one year apart. The children's food-approach and food-avoidance behavior was rated mainly via parent questionnaires at both time points. As expected, lower levels of hot and cool EF predicted a stronger increase in several food-approach eating styles across a 1-year period, mainly in girls. Unexpectedly, poorer performance on the affective decision-making task also predicted an increase in certain food-avoidance styles, namely, slowness in eating and satiety responsiveness, in girls. Results implicate that lower EF is not only seen in eating-disordered or obese individuals but also acts as a risk factor for an increase in particular eating styles that play a role in the development of weight problems in children.

    Full Text Available SummaryBackground: Treatment for inpatients presenting an eating disorder usually implies a therapeutic contract. However,treatment dropout is frequent, costky and leads to poor prognosis.Aim: To identify predictive factors of dropout in inpatients admitted for an eating disorder.Methods: In all, 916 consecutive female inpatients with anorexia nervosa, bulimia nervosa, and atypical bulimia nervosa were assessed at admission between 1988 and 2004 accordingly to ICD-10 classification. Clinical, sociodemographic, and psychological data were collected through questionnaires and interviews. Descriptive, univariate analyses and two logisticmodels were performed: onefor patients with anorexia or bulimia and the other for patientswith atypical bulimia.Results: Dropout rates were 49.6 % for anorexia, 55.6 % for bulimia and 69.3 % for atypical bulimia. For the anorexia/ bulimiamodel, predictive factors were the following:educational status, age at admission, subtype of eating disorder,minimumBMI and “ideal BMI” (calculated on the basis of the question “According to you, what should be your weight after treatment?”, requested upon admission, and without any medical advice. The atypical bulimia model is the first published on female inpatients to date.Psychological scores were not significant factors in both models.Conclusion: the inpatients’ characteristics seem close to those described in the literature. The results of the multivariate analysis were discussed, especially the fact that the psychometric scales had no predictive value.An innovative variable, the ideal BMI signifies that the more a thin patient declares herself ready to gain weight upon admission, the more likely she is to keep to the contract. This study highlights the importance of pre-hospitalisation preparation,particularly in terms of the patients recognising their illness.Prat Organ Soins 2008;39(1:23-32

  16. Does personality influence eating styles and food choices? Direct and indirect effects.

    2015-01-01

    In a random sample (N?=?951) from the general population, direct and indirect effects of the Big Five personality traits on eating styles and food choices were examined. Path models revealed that high openness to experience were associated with higher fruit, vegetable and salad and lower meat and soft drink consumption. High agreeableness was associated with low meat consumption. Neuroticism, conscientiousness and extraversion significantly and directly influenced eating styles and significantly indirectly influenced food choices. Conscientiousness mainly promoted fruit consumption by promoting restrained eating and prevented meat consumption by reducing external eating. Conscientiousness prevented consumption of sweet and savory foods, and of sugar-sweetened soft drinks by promoting restrained eating and reducing external eating, and consumption of sweet and savory foods also by reducing emotional eating. Neuroticism promoted consumption of sweet and savory foods by promoting emotional and external eating. Extraversion promoted sweet and savory, meat and soft drink consumption via promoting external eating. Results suggest that neurotic and emotionally unstable individuals seem to adopt counter-regulatory external or emotional eating and eat high-energy dense sweet and savory foods. Highly conscientious individuals adopt regulatory dietary restraint and practice counter-regulatory emotional or external eating less, resulting in more consumption of recommended and less consumption of not recommended food. The higher sociability of extraverted people, which is basically a health beneficial psychological resource, seems to have health-averse effects. Personality traits are stable; however, the resulting more proximal, counter-regulatory eating styles such as emotional or external eating might be more successfully addressed in interventions to prevent overeating and overweight.

    2012-09-01

    Full Text Available Abstract Background Research results from large, national population-based studies investigating gender differences in weight dissatisfaction and disordered eating across the adult life span are still limited. Gender is a significant factor in relation to weight dissatisfaction and disordered eating. However, the reasons for gender differences in these conditions are still poorly understood. The aim of this study was to examine gender differences in weight dissatisfaction and disordered eating in the general Swiss adult population and to identify gender-specific risk factors. Methods The study population consisted of 18156 Swiss adults who completed the population-based Swiss Health Survey 2007. Self-reported weight dissatisfaction, disordered eating and associated risk factors were assessed. In order to examine whether determinants of weight dissatisfaction and disordered eating (dieting to lose weight, binge eating, and irregular eating differ in men and women, multivariate logistic regressions were applied separately for women and men. Results Although more men than women were overweight, more women than men reported weight dissatisfaction. Weight category, smoking status, education, and physical activity were significantly associated with weight dissatisfaction in men and women. In women, nationality and age were also significant factors. Gender-specific risk factors such as physical activity or weight category were identified for specific disordered eating behaviours. Conclusions The results suggest that gender specific associations between predictors and disordered eating behaviour should be considered in the development of effective prevention programs against disordered eating.

  20. Distinguishing Between Risk Factors for Bulimia Nervosa, Binge Eating Disorder, and Purging Disorder.

    Binge eating disorder and purging disorder have gained recognition as distinct eating disorder diagnoses, but risk factors for these conditions have not yet been established. This study aimed to evaluate a prospective, mediational model of risk for the full range of binge eating and purging eating disorders, with attention to possible diagnostic differences. Specific aims were to determine, first, whether eating, weight and shape concerns at age 14 would mediate the relationship between parent-perceived childhood overweight at age 10 and a binge eating or purging eating disorder between age 15 and 20, and, second, whether this mediational model would differ across bulimia nervosa, binge eating disorder, and purging disorder. Participants (N = 1,160; 51 % female) were drawn from the Western Australian Pregnancy Cohort (Raine) Study, which has followed children from pre-birth to age 20. Eating disorders were assessed via self-report questionnaires when participants were aged 14, 17 and 20. There were 146 participants (82 % female) with a binge eating or purging eating disorder with onset between age 15 and 20 [bulimia nervosa = 81 (86 % female), binge eating disorder = 43 (74 % female), purging disorder = 22 (77 % female)]. Simple mediation analysis with bootstrapping was used to test the hypothesized model of risk, with early adolescent eating, weight and shape concerns positioned as a mediator between parent-perceived childhood overweight and later onset of a binge eating or purging eating disorder. Subsequently, a conditional process model (a moderated mediation model) was specified to determine if model pathways differed significantly by eating disorder diagnosis. In the simple mediation model, there was a significant indirect effect of parent-perceived childhood overweight on risk for a binge eating or purging eating disorder in late adolescence, mediated by eating, weight and shape concerns in early adolescence. In the conditional process model, this significant indirect effect was not moderated by eating disorder group. The results support a prospective model of risk that applies to bulimia nervosa, binge eating disorder and purging disorder. Common prevention approaches may be possible for bulimia nervosa, binge eating disorder and purging disorder. PMID:25233874

    Research has identified multiple factors that predict unhealthy eating practices. However what remains poorly understood are factors that promote healthy eating practices. This study aimed to determine a set of factors that represent a profile of healthy eaters. This research applied Antonovsky's salutogenic framework for health development to examine a set of factors that predict healthy eating in a cross-sectional study of Dutch adults. Data were analyzed from participants (n?=?703) who completed the study's survey in January 2013. Logistic regression analysis was performed to test the association of survey factors on the outcome variable high dietary score. In the multivariate logistic regression model, five factors contributed significantly (p?eating, and self-efficacy for healthy eating. Findings complement what is already known of the factors that relate to poor eating practices. This can provide nutrition promotion with a more comprehensive picture of the factors that both support and hinder healthy eating practices. Future research should explore these factors to better understand their origins and mechanisms in relation to healthy eating practices. PMID:25681292

    Aposematic prey warn predators of their toxicity using conspicuous signals. However, predators regularly include aposematic prey in their diets, particularly when they are in a poor energetic state and in need of nutrients. We investigated whether or not an environmental factor, ambient temperature, could change the energetic state of predators and lead to an increased intake of prey that they know to contain toxins. We found that European starlings, Sturnus vulgaris, increased their consumption of mealworm, Tenebrio molitor, prey containing quinine (a mild toxin) when the ambient temperature was reduced below their thermoneutral zone from 20 °C to 6 °C. The birds differed in their sensitivity to changes in ambient temperature, with heavier birds increasing the number of toxic prey they ate more rapidly with decreasing temperature compared to birds with lower body mass. This could have been the result of their requiring more nutrients at lower temperatures or being better able to detoxify quinine. Taken together, our results suggest that conspicuous coloration may be more costly at lower temperatures, and that aposematic prey may need to invest more in chemical defences as temperatures decline. Our study also provides novel insights into what factors affect birds' decisions to eat toxic prey, and demonstrates that selection pressures acting on prey defences can vary with changing temperature across days, seasons, climes, and potentially in response to climate change.

    Full Text Available Purpose : The purpose of this study was to evaluate the timing of puberty and the factors inducing advanced puberty in elemental school students of low grades. Methods : The 1st, 2nd, and 3rd grade elemental students from the Goyang province were randomly selected, and their sexual maturation rate was assessed by physical examination. After obtaining an informed consent, a questionnaire was administered to the parents; eating habits, lifestyle, use of growth-inducing medication, and present illness of the students were evaluated to determine the factors that induced advanced puberty. The data were statistically analyzed. Results : We selected 170 children and the girls:boys sex ratio was 1.2:1. Two 9-year-old boys were in genital stage 2. Two (14.3% 6-year-old girls, 6 (19.4% 7-year-old girls, 15 (39.6% 8-year-old girls, and 4 (57.1% 9-year-old girls were in breast stage 2. The average pubertal timing predicted for girls was 9.11¡?#?.86; years. The main factors influencing pubertal timing were obesity scale, frequency of eating fast food, and the use of growth-inducing medication. A high rating on the obesity scale and high frequency of eating fast food indicated advanced stage of puberty. Growth-inducing medication induced puberty through obesity. Conclusion : We proposed that predictive average pubertal timing in girls was 9.11¡?#?.86; years, which was consistent with the previously reported findings from abroad. The significant influencing factors in advanced puberty were obesity scale and frequency of fast food.

    Eating competence is an attitudinal and behavioral concept, based on The Satter Eating Competence Model. In adults, it has been shown to be associated with a higher quality of diet. Eating competence or its association with the quality of diet has not been studied in adolescents. The aim of the current study was to explore the utility of using a preliminary Finnish translation of the ecSI 2.0 for evaluating presumed eating competence and its association with food selection, meal patterns and related psychobehavioral factors in 10–17 year old adolescents. Altogether 976 10–17 years old Finnish adolescents filled in the study questionnaire. When exploring the construct validity of ecSI 2.0, the confirmatory factor analysis (CFA) indicated acceptable model fit and all four components of the ecSI 2.0 (eating attitudes, food acceptance, internal regulation of food intake, management of eating context) correlated with each other and were internally consistent. Over half (58%) of the adolescents scored 32 or higher and were thus classified as presumably eating competent (pEC). Eating competence was associated with greater meal frequency, more frequent consumption of vegetables and fruits, and more health-promoting family eating patterns. In addition the pEC, adolescents more often perceived their body size as appropriate, had less often tried to lose weight and had a higher self-esteem and a stronger sense of coherence than the not pEC ones. Family eating patterns and self-esteem were the main underlying factors of eating competence. In conclusion, this preliminary study suggests eating competence could be a useful concept to characterize eating patterns and related behaviors and attitudes in adolescents. However, these preliminary findings need to be confirmed in further studies with an instrument fully validated for this age group. PMID:26007335

    People's eating behaviors tend to be influenced by the behaviors of others. In the present studies, we investigated the effect of another person's eating behavior and body weight appearance on healthy food consumption of young women. In Study 1, participants watched a short film fragment together with a confederate who appeared normal weight or overweight and consumed either 3 or 10 cucumber slices. In Study 2, a confederate who appeared underweight, normal weight, or overweight consumed no or 4 cucumber slices. The number of cucumber slices eaten by participants was registered. Results showed that participants' healthy eating behavior was influenced by the confederate's eating behavior when the confederate was underweight, normal weight, and overweight. Participants ate more cucumber slices when the confederate ate a higher amount of cucumber slices compared with a lower (or no) amount of cucumber slices (Studies 1 and 2). The food intake effect was stronger for the underweight compared with the overweight model (Study 2). PMID:25794685

    The Diagnostic and Statistical Manual of Mental Disorders (i.e., DSM-5) currently recognizes three primary eating disorders: anorexia nervosa, bulimia nervosa, and binge eating disorder. The origins of eating disorders are complex and remain poorly understood. However, emerging research highlights a dimensional approach to understanding the multifactorial etiology of eating disorders as a means to inform assessment, prevention, and treatment efforts. Guided by research published since 2011, this review summarizes recent findings elucidating risk factors for the development of eating disorders across the lifespan in three primary domains: (1) genetic/biological, (2) psychological, and (3) socio-environmental. Prospective empirical research in clinical samples with full-syndrome eating disorders is emphasized with added support from cross-sectional studies, where relevant. The developmental stages of puberty and the transition from adolescence to young adulthood are discussed as crucial periods for the identification and prevention of eating disorders. The importance of continuing to elucidate the mechanisms underlying gene by environmental interactions in eating disorder risk is also discussed. Finally, controversial topics in the field of eating disorder research and the clinical implications of this research are summarized. PMID:25894358

Transcript data obtained was analysed using the thematic approach of the framework method. Findings indicated that school support for NE was limited, which undermined the capacity of school NE to influence healthy eating behaviours of learners. The need to strengthen teachers' capacity to model positive eating behaviours was identified. Learners were perceived as being not completely ignorant of healthy eating, with limited capacity to effect changes within the resource-constrained environment. Negative influences like unhealthy choices of food from food vendors and peer influences were identified as needing to be discouraged. Positive influences like the National School Nutrition Programme (NSNP) and the school vegetable garden were to be encouraged. Understanding the prevailing school situation and environment and teachers' perceptions and roles in school NE is important in addressing issues that weaken the influence of NE on learners' eating behaviours.

    Eating frequency may be important in the development of overweight and obesity and other cardiometabolic risk factors; however, the evidence is inconsistent. The aim of the present study was to examine the associations between the number of eating occasions and cardiometabolic risk factors in a national population-based sample of young adults. A cohort of 1273 men and 1502 women, aged 26-36 years, completed a meal pattern chart to record when they had eaten during the previous day (in hourly intervals). The total number of eating occasions was calculated. Diet quality was assessed, waist circumference was measured and a fasting blood sample was taken. Dietary intake was compared with the Australian Guide to Healthy Eating. The associations between the number of eating occasions and cardiometabolic risk factors were calculated using linear regression. Analyses were adjusted for age, education and physical activity. Most men ate three to five times per d and most women ate four to six times. The proportion of participants meeting dietary recommendations increased with the number of eating occasions. For men, an additional eating occasion was associated with reductions in mean values for waist circumference (-0·75 cm), fasting glucose (-0·02 mmol/l), fasting insulin (-0·34 mU/l; 2·04 pmol/l), TAG (-0·03 mmol/l), total cholesterol (-0·08 mmol/l) and LDL-cholesterol (-0·06 mmol/l). Adjustment for waist circumference attenuated the results. Significant trends were not observed for women. In conclusion, a higher number of eating occasions were associated with reduced cardiometabolic risk factors in men. Many associations were mediated by waist circumference. PMID:22177728

    Full Text Available Abstract Background Slow eating has been associated with enhanced satiation, but also with increased water intake. Therefore, the role of water ingestion in regard to eating rate needs to be discerned. This study examined the influence of eating rate on appetite regulation and energy intake when water intake is controlled. Methods In a randomized design, slow and fast eating rates were compared on two occasions, in 30 women (22.7±1.2y; BMI=22.4±0.4kg/m2 who consumed an ad libitum mixed-macronutrient lunch with water (300 mL. Satiation was examined as the main outcome by measuring energy intake during meals. At designated times, subjects rated hunger, satiety, desire-to-eat, thirst, and meal palatability on visual analogue scales. Paired t-tests were used to compare hypothesis-driven outcomes. Appetite ratings were compared across time points and conditions by repeated measures analysis of variance (ANOVA using a within-subject model. Results Energy intake and appetite ratings did not differ between conditions at meal completion. However, subjects rated less hunger and tended to rate lower desire-to-eat and greater satiety at 1 hour following the slow condition. Conclusions Results tend to support a role of slow eating on decreased hunger and higher inter-meal satiety when water intake is controlled. However, the lack of significant differences in energy intake under these conditions indicates that water intake may account for the effects of eating rate on appetite regulation.

    2000-11-01

    OBJECTIVES: Review the literature, exploring factors that contribute to the development of children's eating behavior such as the role of learning and social context. METHODS: The review of the literature was done using Medline, Psyclit, and Lilacs as resources for assessing international and national research articles on child nutrition, with an emphasis on children's eating behavior. These articles were revised and grouped together according to the topic. RESULTS: Family is responsible for the development of children's eating behavior through social learning. Parents are children's first nutritional educators. Children's eating experiences are influenced by cultural and psychosocial factors. Social context plays a relevant role in this process, especially through the strategies used by parents to encourage children to have a balanced diet and to eat specific foods. These strategies may contain adequate and inadequate stimuli as to the development of children's food preference and food intake self-control. CONCLUSION: The learning process is a determining factor for children's eating behavior, and is associated with three factors: food flavor conditioning, food postingestional consequences, and social context. Parents are deeply concerned with the amount of food their children eat and not with the development of more adequate habits and attitudes related to dietary quality. PMID:14676901

  16. The Tripartite Influence model of body image and eating disturbance: a covariance structure modeling investigation testing the mediational role of appearance comparison.

    2002-11-01

    Recent theoretical approaches to the etiology of eating disorders and body image disturbances have begun to focus on multifactorial models. In the current study, the Tripartite Influence model was examined in a large sample of college females (ages 18-22). This model proposes that three primary core sources of influence--parents, peers and media--contribute to the development of body image and eating disturbances. Additionally, the model suggests that at least two factors mediate the relationship between influences and disturbance-appearance comparison and internalization of media information. In this study, appearance comparison was examined as a mediational link between peer, family and media influence variables and the outcome disturbance measures of eating dysfunction and body image dissatisfaction. Covariance structure modeling (CSM) was used to test the proposed pathways. The results indicated that appearance comparison mediated the effects of family and media influences on body dissatisfaction, which in turn influenced restrictive and bulimic behaviors. In addition, peer influences had a direct influence on restriction. Perfectionism was hypothesized to relate to body dissatisfaction, but was in fact found to influence appearance comparison. The findings were limited by the necessity of several modifications to the originally proposed models, yet offer replication and extension of previous work with appearance comparison and support for further testing of the Tripartite Influence model.

    While perfectionism is widely considered to influence risk for eating disorders, results of longitudinal studies are mixed. The goal of the current study was to investigate a more complex model of how baseline perfectionism (both high personal standards and self-critical evaluative concerns) might influence change in risk status for eating disorders in young adolescent girls, through its influence on ineffectiveness. The study was conducted with 926 girls (mean age of 13 years), and involved three waves of data (baseline, 6- and 12-month follow-up). Latent growth curve modelling, incorporating the average rate at which risk changed over time, the intercept (initial status) of ineffectiveness, and baseline perfectionism, was used to explore longitudinal mediation. Personal standards was not supported as contributing to risk but results indicated that the higher mean scores on ineffectiveness over the three waves mediated the relationship between higher baseline self-critical evaluative concerns and both measures of eating disorder risk. The relationship between concern over mistakes and change in risk was small and negative. These results suggest the usefulness of interventions related to self-criticism and ineffectiveness for decreasing risk for developing an eating disorder in young adolescent girls. PMID:25698165

    Obesity during childhood and adolescence is a growing problem in the United States, Canada, and around the world that leads to significant physical, psychological, and social consequences. Peer experiences have been theoretically and empirically related to the "Big Two" contributors to the obesity epidemic, unhealthy eating and physical inactivity. In this article, we synthesize the empirical literature on the influence of peers and friends on youth's eating and physical activity. Limitations and issues in the theoretical and empirical literatures are also discussed, along with future research directions. In conclusion, we argue that the involvement of children's and adolescents' peer networks in prevention and intervention efforts may be critical for promoting and maintaining positive behavioral health trajectories. However, further theoretical and empirical work is needed to better understand the specific mechanisms underlying the effects of peers on youth's eating and physical activity. PMID:22480733

    The need has never been greater to support healthy eating and physical activity in children and youth; the numbers of overweight and obese children have doubled and tripled, respectively, over the past 3 decades. Poor eating habits, including inadequate intake of vegetables, fruit, and milk, and eating too many high-calorie snacks, play a role in childhood obesity. Grain products provide the highest percentage (31%) of daily calories, followed by "other foods," which have limited nutritional value (22% of daily calories). Snacks account for 27% of total daily calories, which is more than the calories consumed at breakfast (18%) and lunch (24%), but not dinner (31%). For Canadians older than 4 years of age, more than 41% of daily snack calories come from other foods, such as chips, chocolate bars, soft drinks, fruit drinks, sugars, syrup, preserves, fats, and oils. Habits that protect against childhood obesity include eating more vegetables and fruit, eating meals with family, and being physically active. Children's food habits and choices are influenced by family, caregivers, friends, schools, marketing, and the media. Successful interventions for preventing childhood obesity combine family- and school-based programs, nutrition education, dietary change, physical activity, family participation, and counseling.

    Full Text Available Abstract Background Despite the increasing prevalence of overweight/obesity and its association to eating patterns in adolescents and adults, little is known about the relationship between problematic eating behaviours and body weight in the preschool years within the context of various social factors. This research aims to analyze the relationship between social factors, mothers' perceptions of their child's eating behaviour (picky eating and overeating, and body weight in preschool years, in a population-based cohort of preschoolers from Québec (Canada. Methods Analyses were performed on 1498 children from the Longitudinal Study of Child Development in Québec, a representative sample of children born in 1998 in the Canadian province of Québec. Eating behaviours (picky eating and overeating were derived from questionnaires at 2.5, 3.5, and 4.5 years of age. BMI was calculated from children's measured height and weight at 4.5 years. Children's sex and birth weight, mothers' age, immigrant status, smoking status during pregnancy, and education level, family type, annual household income and income sufficiency, the number of overweight/obese parents, children's day-care attendance, and food insufficiency were part of the analysis. Multivariate logistic regressions were used to determine odds ratios for different body weight profiles (underweight, normal weight, at risk of overweight, overweight, and one-way analysis-of-variances (ANOVA allowed for group comparisons of means. Results The proportion of children reported for each eating behaviour category remained quite stable across the years studied. Picky eating and overeating related to body weight among 4.5-year-old children, even when social and parental factors were accounted for in multivariate analysis. Picky eaters were twice as likely to be underweight at 4.5 years as children who were never picky eaters. Adjusted odds ratios revealed overeaters were 6 times more likely to be overweight at 4.5 years than were children who were never overeaters. Conclusion Given the association between eating behaviours and bodyweight among 4.5-year-old children, particularly among those from less educated, lower income families and younger mothers, health professionals should target parents of children at risk of overweight/obesity and underweight with focussed messages and strategies for the management of emerging problematic eating behaviours.

    In general, vegetables are abundantly consumed in a calorie-restricted diet to achieve sufficient satiety through fresh food or various cooking methods. In this study, we examined the effects of different cooking methods on appetite and specific perceptions of the food after consumption; eating approaches were also analyzed by meal duration. A total of 153 individuals aged 20-59 years were assigned to 2 groups: raw vegetable or boiled vegetable meals, including packed meals that were served as test meals with the same energy and vegetable amount. Subjective levels of sensory properties and meal duration were assessed over time using visual analog scales, including questionnaires. Results showed that meal duration was significantly longer for raw vegetable meals than boiled vegetable meals, and there were significantly stronger correlations between meal duration and fullness. A higher degree of fullness was provided by a raw vegetable meal than a boiled vegetable meal, especially in men. However, an excess of raw vegetables led to overall insufficient satisfaction. Taken together, these findings suggest that cooking methods should be altered for different situations with an adequate amount of vegetables, and the meal duration should be recommended to be given as much attention as cooking methods.

This study was therefore undertaken to probe the different eating practices among an adult sample population in Mauritius in an endeavor to establish significant relationships, if any, with common socio-demographic and socio-economic factors. A self-designed questionnaire, (randomly distributed to n = 387 adults, pertaining to socio-demographic variables, vegetarianism, breakfast patterns, eating out of home meals (OHMs, food frequency questions and dieting practices were asked. Males (21 - 40 yrs had a significantly (p < 0.05 higher consumption of OHM at lunch. Higher mean frequencies of consuming OHMs were found amid specific groups (e.g. amongst professionals as compared to each of manual workers, unemployed, retired and self-employed which also depicted significantly lower percentages of adhesion to the WHO recommended daily intake of vegetables. Oily foods were frequently consumed by males (41 - 60 yrs whereas none of the socio-demographic factors assessed revealed a significant relationship (p > 0.05 to adherence to the recommendations for the consumption of fish. The socio-demographic factors most influential towards eating practices were gender, age and socio-economic status represented by education and occupation. In conclusion, relationships recorded in the present study were comparable to Western eating practices and the availability of certain foods has compelled Mauritians to develop its own and unique eating patterns which can be of relevance in providing accurate health targets for future nutrition interventions in Mauritius.

    Conducted exploratory and confirmatory factor analysis of the About Your Child's Eating (AYCE) inventory with 763 parents. Parent subjects were drawn from a community study of families with physically healthy and chronically ill children between 8 and 16 years of age. Three correlated factors were identified: Child Resistance to Eating, Positive Mealtime Environment, and Parent Aversion to Mealtime. The internal consistency of the factors remained satisfactory across all examined demographic subgroups. Evidence for convergent validity was found by comparing the AYCE factors to higher order factors of the Family Environment Scale. Empirically derived clinical range cut-off scores are presented. Results support the AYCE as a psychometrically sound measure of the parent-child feeding relationship for school-aged children. PMID:17950934

    Full Text Available Ramadan is one of the special months for Muslims all over the world. During Ramadan, able?bodied Muslims are abstained from eating, drinking and even smoking from dawn to sunset. In Malaysia, the duration of fasting are normally around 13 hours at any time of the year as it is located near the equator. The altered food intake timing and long period of fasting do influence on eating behavior of fasting individuals. This is especially on those who do not know the right meals to eat during the time of breakfast. Hence, this issue may favor those intended to organize Ramadan Bazaar along the streets and Ramadan buffets in hotels. The implications of these two phenomena which create an abundant food environment may lead to food wasting, binge eating and overeating. However, this may benefit the country’s economy; the Muslims need to be mindful that Ramadan is a month of moderation. Hence, the food carnivals during Ramadan need to be observed wisely for the benefit of the ritual and in point of view of population health.

    Full Text Available The development of eating behaviours is a dynamic process that begins in infancy and continues throughout life, being strongly influenced by the family models. Our study aimed to evaluate the food behaviour in children aged 11, 13 and 15 years old in relation to the family models. We did a cross-sectional study in 206 school children from Sibiu county (rural and urban areas using the Romanian version of HBSC questionnaire. We analysed the frequency of breakfast and dinner with the family, the lunch circumstances, the frequency of snacks during playtime or computer work, the family influence on the consumption of certain unhealthy foods, the frequency of fast-food restaurants attendance and the compliance of family dining rules. High proportions of children were found not to have breakfast with family, to eat snacks during playtime and to receive soft drinks, sweets and chips without restriction. Also a high proportion of children in urban areas use to have the lunch at school (as a snack due to the school program. By opposite, the situation seemed much better in relation to dinner, most of the children having daily dinners with their parents. Also a low percent of children use to visit the fast food restaurants. Moderate compliance was found in relation to family dining rules. This results are quite concerning, showing limited involvement of the parents and moderate influence of family modelling in relation to the children eating behaviour.

    Research suggests that individuals with binge eating pathology (e.g., bulimia nervosa (BN) and binge eating disorders (BED)) have decision making impairments and particularly act impulsively in response to negative affect. The aim of this study was to examine the influence of negative affect on choice behavior in women with BN and BED. Ninety women (59 with BN or BED and 31 healthy controls) watched a sad or control film fragment and were subsequently asked to complete a choice behavior task (as measured by a variation of the Bechara Gambling Task (BGT)). Results showed that negative affect influenced choice behavior differently in healthy controls and in women with BN and BED after punishment (but not after reward). In the context of increased negative affect, punishment was associated with more disadvantageous choice behavior in both BN and BED women but not in healthy controls, while the effect was the exact opposite in both groups after a decrease in negative affect. Levels of sadness were not found to influence choice behavior after reward in either groups. These findings suggest that emotional states may have a direct impact on choice behavior of individuals with binge eating pathology and are not only related to pathological behavior itself.

    Parents have a high degree of control over the environments and experiences of their children. Food preferences are shaped by a combination of genetic and environmental factors. This article is a review of current data on effective determinants of children's eating habits. The development of children's food preferences involves a complex interplay of genetic, familial, and environmental factors. There is evidence of a strong genetic influence on appetite traits in children, but environment plays an important role in modeling children's eating behaviors. Parents use a variety of strategies to influence children's eating habits, some of which are counterproductive. Overcontrol, restriction, pressure to eat, and a promise of rewards have negative effects on children's food acceptance. Parents' food preferences and eating behaviors provide an opportunity to model good eating habits. Satiety is closely related to diet composition, and foods with low energy density contribute to prevent overeating. Parents should be informed about the consequences of an unhealthy diet and lifestyle and motivated to change their nutritional habits. Parents should be the target of prevention programs because children model themselves on their parents' eating behaviors, lifestyles, eating-related attitudes, and dissatisfaction regarding body image. Pediatricians can have an important role in the prevention of diet-related diseases. Informed and motivated parents can become a model for children by offering a healthy, high-satiety, low-energy-dense diet and promoting self-regulation from the first years of life. PMID:22089441

    The beneficial effects of adiponectin and its negative correlation with BMI are well described. Adiponectin serum levels are altered in eating disorders such as anorexia nervosa, bulimia nervosa or binge eating. Here, we tested the hypothesis that (1) adiponectin serum levels correlate with human eating behavior factors and (2) that genetic variants of the ADIPOQ locus influence both serum levels and eating behavior. We analyzed 11 SNPs within ADIPOQ and in the 5? UTR and measured serum adi...

    2015-03-01

    Although research has consistently documented the prevalence and negative health implications of weight stigma, little is known about the stigma associated with eating disorders. Given that weight stigma is a risk factor associated with disordered eating, it is important to address stigma across the spectrum of eating and weight disorders. The aim of this review is to systematically review studies in the past 3 years evaluating stigma in the context of obesity and eating disorders (including binge eating disorder, bulimia nervosa, and anorexia nervosa). Physical and psychological health consequences of stigma for individuals with obesity and eating disorders are discussed. Recent studies on weight stigma substantiate the unique influence of stigma on psychological maladjustment, eating pathology, and physiological stress. Furthermore, research documents negative stereotypes and social rejection of individuals with eating disorder subtypes, while attributions to personal responsibility promote blame and further stigmatization of these individuals. Future research should examine the association of stigma related to eating disorders and physical and emotional health correlates, as well as its role in health-care utilization and treatment outcomes. Additional longitudinal studies assessing how weight stigma influences emotional health and eating disorders can help identify adaptive coping strategies and improve clinical care of individuals with obesity and eating disorders.

    Purpose . To identify the influence of gender stereotypes on eating habits among Costa Rican adolescents. Design . Qualitative, descriptive research was used in this study. Setting . Adolescents and parents were recruited from socioeconomically diverse populations in rural and urban areas of San José, Costa Rica. Subjects . Subjects were 92 adolescents (14 to 17 years old) and 48 parents. Methods . Focus group data were transcribed and entered into the qualitative data analysis software Atlas.ti version 5.0. Analyses were grounded on the social cognitive theory. Results . Five themes emerged from the focus group discussions: (1) Costa Rican adolescents associate the consumption of moderate quantities of healthy foods with femininity and male homosexuality. (2) The consumption of hearty portions of nonhealthy foods was associated with masculinity and male heterosexuality. (3) There is an emerging view that it is acceptable for heterosexual male adolescents to take care of their bodies through healthy eating. (4) Body care among female adolescents is an element of femininity and body image. (5) Parents reinforce their daughters' persistent concern with weight control because they perceive it as feminine behavior. Conclusion . Health promoters should be aware of the existing and changing food stereotypes around gender as an avenue for the promotion of healthy eating. PMID:24720390

    Evidence of the relation of complications occurring in the pregnancy, delivery and neonatal periods to the risk of contracting a subsequent eating disorder has been obtained during recent years. Factors associated with parturition and neonatal period seem to predict both anorexia and bulimia, whereas disorders during pregnancy are more clearly associated with the descendant's anorexia. This difference may play an important role in the pathogenesis of the disorders. PMID:19341025

  3. What factors influence mitigative capacity?

    International Nuclear Information System (INIS)

    This article builds on Yohe's seminal piece on mitigative capacity, which elaborates 'determinants' of mitigative capacity, also reflected in the IPCC's third assessment report. We propose a revised definition, where mitigative capacity is a country's ability to reduce anthropogenic greenhouse gas emissions or enhance natural sinks. By 'ability' we mean skills, competencies, fitness, and proficiencies that a country has attained which can contribute to GHG emissions mitigation. A conceptual framework is proposed, linking mitigative capacity to a country's sustainable development path, and grouping the factors influencing mitigative capacity into three main sets: economic factors, institutional ones, and technology. Both quantitative and qualitative analysis of factors is presented, showing how these factors vary across countries. We suggest that it is the interplay between the three economic factors-income, abatement cost and opportunity cost-that shape mitigative capacity. We find that income is an important economic factor influencing mitigative capacity, while abatement cost is important in turning mitigative capacity into actual mitigation. Technology is a critical mitigative capacity, including the ability to absorb existing climate-friendly technologies or to develop innovative ones. Institutional factors that promote mitigative capacity include the effectiveness of government regulation, clear market rules, a skilled work force and public awareness. We briefly rk force and public awareness. We briefly investigate such as high abatement cost or lack of political willingness that prevent mitigative capacity from being translated into mitigation

    Full Text Available Abstract Background The deterioration of the health status of the Romanian population during the economic transition from a centrally planned to a free market economy has been linked to lifestyles factors (e.g. diet regarded as a main determinants of the disparity in life expectancy between Eastern and Western Europe. Reforms in the health care system in this transition economy aim to focus on preventive action. The purpose of this study was to identify the factors that impact on the individual decision to engage in Dietary Health Preventive Behaviour (DHPB and investigate their influence in the context of an adapted health cognition model. Methods A population-based study recruited 485 adult respondents using random route sampling and face-to-face administered questionnaires. Results and discussion Respondents' health motivation, beliefs that diet can prevent disease, knowledge about nutrition, level of education attainment and age have a positive influence on DHPB. Perceived barriers to healthy eating have a negative impact on alcohol moderation. The information acquisition behaviour (frequency of reading food labels is negatively predicted by age and positively predicted by health motivation, education, self-reported knowledge about nutrition and household financial status. A significant segment of respondents believe they are not susceptible to the elicited diseases. Health promotion strategies should aim to change the judgments of health risk. Conclusion The adaptation of the Health Belief Model and the Theory of Health Preventive Behaviour represents a valid framework of predicting DHPB. The negative sign of perceived threat of disease on DHPB may suggest that, under an income constraint, consumers tend to trade off long-term health benefits for short-term benefits. This cautions against the use of negative messages in public health campaigns. Raising the awareness of diet-disease relationships, knowledge about nutrition (particularly sources and risks associated with dietary fat and cholesterol may induce people to adopt preventive dietary habits.

  5. A narrative review of binge eating and addictive behaviors: Shared associations with seasonality and personality factors

    Full Text Available Binge eating disorder (BED and seasonal affective disorder (SAD were first described as clinically-relevant conditions in very close temporal proximity a few decades ago. Both disorders have a higher prevalence rate in woman than in men, are characterized by a high proneness-to-stress and manifest heightened responsiveness to high-calorie, hyper-palatable foods. In recent years, a compelling body of evidence suggests that foods high in sugar and fat have the potential to alter brain reward circuitry in a manner similar to that seen when addictive drugs like alcohol and heroin are consumed in excess. These findings have led to suggestions that some cases of compulsive overeating may be understood as an addiction to sweet, fatty, and salty foods. In this paper, it is proposed that high seasonality is a risk factor for binge eating, especially in those characterized by anxious and impulsive personality traits – associations that could only occur in an environment with a superfluity of, and easy access to, rich and tasty foods. Given the well-established links between binge eating and addiction disorders (22-24 for reviews, it is also suggested that seasonality, together with the same high-risk psychological profile, exacerbates the likelihood of engaging in a broad range of addictive behaviors. Data from a community sample (n=412 of adults tested these models using linear regression procedures. Results confirmed that symptoms of binge eating and other addictive behaviors were significantly inter-correlated, and that seasonality, gender, and addictive personality traits were strong statistical predictors of the variance in binge-eating scores. Seasonality and addictive personality traits also accounted for a significant proportion of the variance in the measure of addictive behaviors. Conclusions are discussed in the context of brain reward mechanisms, motivational alternations in response to chronic over-consumption, and their relevance for the treatment of excess

    Despite the recognition that environments play a role in shaping physical activity and healthy eating behaviors, relatively little research has focused on rural homes and neighborhoods as important settings for obesity prevention. This study, conducted through community-based participatory research, used a social ecological model to examine how home and neighborhood food and physical activity environments were associated with weight status among rural-dwelling adults. Data were from a cross-sectional survey of White and African American adults (n?=?513) aged 40-70 years living in rural southwest Georgia. Data were analyzed using measured variable path analysis, a form of structural equation modeling. The results support a social ecological approach to obesity prevention. Physical activity had a direct effect on BMI; self-efficacy, family support for physical activity, and household inventory of physical activity equipment also had direct effects on physical activity. Neighborhood walkability had an indirect effect on physical activity through self-efficacy and family social support. Although neither fruit and vegetable intake nor fat intake had direct effects on BMI, self-efficacy and household food inventories had direct effects on dietary behavior. Perceived access to healthy foods in the neighborhood had an indirect effect on healthy eating and a direct effect on weight; neighborhood cohesion had an indirect effect on healthy eating through self-efficacy. Overall, individual factors and home environments tended to exhibit direct effects on behavior, and neighborhood variables more often exhibited an indirect effect. PMID:23408285

    The relative impact of genetic and social influences on disordered eating behaviors (DEB) including binging, purging, excessive dieting and negative self-evaluations about weight remain an issue of debate. The current study sought to examine the relative influence of genetic and social influences on DEB. A 7-year prospective analysis of 580 monozygotic (MZ) and dizygotic (DZ) twins was conducted. Estimates of heritability of DEB were obtained using the DF Analysis Model. Regression equations revealed the relative predictive value of sibling's DEB, neurotic personality, maternal warmth and television and video game exposure on DEB. Heritability estimates for DEB were 0.40 for females and 0.48 for males. Among MZ and DZ twin pairs, female sex, neurotic personality and a genetic variable component, but not maternal warmth or school related problems, predicted DEB. Contrary to the expectations of media effects theory, greater media use was associated with lower DEB among DZ twins and had no influence on MZ twins. These results indicate that DEB is highly heritable and that personality variables may play an important role in the formation of DEB. This suggests that it is important to control for genetic variables when analyzing risk factors for DEB. PMID:22278805

    This study examines putative non-sport-specific and sport-specific risk factors for eating disorders (ED) among groups of professional female athletes versus non-athletes. In detail, societal pressure to be thin, its internalisation, body dissatisfaction, sports pressure and early specialisation were investigated. The cross-sectional study included 46 aesthetic and 62 ball game sports athletes, and 108 age-matched non-athletes. Study methods comprised a clinical interview to detect ED and questionnaires. More athletes from aesthetic (17%) than from ball game sports (3%) and non-athletes (2%) suffered from ED. Aesthetic sports athletes did not differ from non-athletes in non-sport-specific factors but obtained higher levels than ball game sports athletes in sport-specific variables (p?disordered eating, with sports pressure and body dissatisfaction as significant predictors. The results confirm ED risk for German aesthetic athletes and indicate the importance of sports pressure and body dissatisfaction in explaining athletes' vulnerability.

    Full Text Available Abstract Background The long-term role that parental encouragement and attitudes about fitness and exercise play in adolescents' physical activity and sedentary behavior habits remains unclear. This paper aims to longitudinally examine how parental encouragement to be physically active and parental concern about staying fit are associated with adolescents' physical activity and sedentary behavior habits five years later. Methods Project EAT-II adolescent and young adult participants (1130 male, 1386 female completed surveys while in middle school or high school (1998–1999, and again 5 years later. Participants were asked whether their mother and father encourage them to be physically active and care about staying fit and exercising. Adolescent moderate and vigorous physical activity (MVPA and TV/video watching (hours/week were assessed. Linear regression models adjusted for socio-demographic characteristics and baseline behavior were used to examine the association of Time 1 parental factors with behavioral outcomes among adolescents and young adults five years later (Time 2. Results After adjustment for socio-demographic characteristics and baseline MVPA, adolescent-reported maternal and paternal encouragement to be active, and paternal care for fitness, were positively associated with weekly hours of MVPA after five years in young adult males (p for trend ? .01. The positive relationship between maternal encouragement and MVPA approached significance among high-school aged females (p for trend = .06, and paternal encouragement was positively related to MVPA among high-school aged males (p for trend = .02. While maternal encouragement to be active was associated with decreased TV/video time among younger females (p for trend = .02, other parental factors were not associated with lower TV/video time among the other groups. Conclusion Parental encouragement to be active was associated with increased physical activity among males and younger females 5 years later. Younger adolescents appear to be especially influenced by their same-sex parent. These findings suggest that encouragement may be more influential than parental concern for fitness on adolescents' physical activity habits. Further research is needed to determine how parents can help adolescents decrease sedentary behavior time.

In a correlational study, 126 Israeli college students completed two measures of emotional intelligence, a brief five-factor personality test, demographic data questionnaires, and questionnaires assessing food preoccupation, namely, the Body Weight, Image and Self-Esteem Scale and the Appearance Schema Inventory. Results suggested that ability emotional intelligence is associated with disordered eating beyond gender and personality. Self-reported emotional intelligence did not associate with any of the outcomes after controlling for personality. Implications and applications are briefly discussed. PMID:23682062

    Appetite and eating are not only controlled by energy needs, but also by extrinsic factors that are not directly related to energy balance. Environmental signals that acquire motivational properties through associative learning—learned cues—can override homeostatic signals and stimulate eating in sated states, or inhibit eating in states of hunger. Such influences are important, as environmental factors are believed to contribute to the increased susceptibility to overeating and the rise ...

This study is an extensive review of the literature regarding DO predictors in EDs. Methods All papers in PubMed, PsycINFO and Cochrane Library (1980-2009 were considered. Methodological issues and detailed results were analysed for each paper. After selection according to inclusion criteria, 26 studies were reviewed. Results The dropout rates ranged from 20.2% to 51% (inpatient and from 29% to 73% (outpatient. Predictors of dropout were inconsistent due to methodological flaws and limited sample sizes. There is no evidence that baseline ED clinical severity, psychiatric comorbidity or treatment issues affect dropout. The most consistent predictor is the binge-purging subtype of anorexia nervosa. Good evidence exists that two psychological traits (high maturity fear and impulsivity and two personality dimensions (low self-directedness, low cooperativeness are related to dropout. Conclusion Implications for clinical practice and areas for further research are discussed. Particularly, these results highlight the need for a shared definition of dropout in the treatment of eating disorders for both inpatient and outpatient settings. Moreover, the assessment of personality dimensions (impulse control, self-efficacy, maturity fear and others as liability factors for dropout seems an important issue for creating specific strategies to reduce the dropout phenomenon in eating disorders.

    We investigated eating- and weight-related correlates of self-evaluation influences (SEIs) and examined the extent to which such SEIs can be both over- and undervalued and the extent to which measurement strategy affects SEIs. A female undergraduate sample (n = 549) completed 3 measures of SEI importance and questionnaires assessing disordered eating (DE), body mass index (BMI), and depression. SEI measures included Likert scale, rank ordering, and pairwise forced choice; a subset (n = 62) also completed the Shape- and Weight-Based Self-Esteem Scale (SAWBS). Only rank ordering, forced choice, and SAWBS constrain choices among SEIs, such that prioritizing one SEI necessarily deprioritizes another, which reflects real-world restrictions on individuals' allotment of time and energy (e.g., spending hours exercising daily necessarily reduces time available for other activities). By any measure, women with DE overvalue body shape and weight. The constraining measures reveal systematic undervaluation of intelligence and achievement among women with DE and an enhanced effect of DE on the overvaluation of weight and on the undervaluation of being a good person among those with higher BMI. Depressed women's self-evaluations overemphasize appearance and underemphasize interpersonal relationships. Self-evaluations of women with DE are marked by both over- and undervaluation of relevant SEIs; the overvaluation of shape and weight in DE may be associated with costs. Future use of constraining measures, such as forced choice or rank ordering, may enhance our understanding of both over- and underemphasized SEIs among women with DE. PMID:24854805

    Culture-based contributors play a role in eating disorders (EDs). Here, we present one such factor that may play a role in triggering ED's in adolescents: Fasting during the holy period of Ramadan. Ramadan is the Islamic month of fasting, in which participating Muslims refrain from eating, drinking, and smoking, which starts from dawn lasting until sunset. For the past 2 years, we have noticed an increase in patients with disordered eating patterns that have applied to Hacettepe University, Division of Adolescent Medicine during or shortly after Ramadan. We document six of these patients, three of which were diagnosed with an ED and three that did not meet full criteria. We argue that the possible effects of a drastic change in ones diet such as that which occurs during Ramadan, play an important role in triggering ED's in adolescents with a predisposition or may exacerbate an eating pathology.

    Full Text Available Objetivo: El primer objetivo del estudio es evaluar restrospectivamente, la relevancia de factores de riesgo en pacientes con Trastorno de la Conducta Alimentaria (TCA) en función de la categoría diagnóstica. El segundo objetivo, es evaluar la psicopatología alimentaria, la insatisfacción corporal y [...] el funcionamiento psicológico en cada grupo diagnóstico. Método: Se evalúa en el momento previo al tratamiento de TCA, un total de 73 pacientes con diferentes criterios diagnósticos: Bulimia Nerviosa Purgativa (BN-P; n=29), la provisional forma diagnóstica del Trastorno por Atracón (TA; n=6), el Trastorno de la Conducta Alimentaria No Especificado tipo Purgativo (TCANE-P; n=17) y el Trastorno de la Conducta Alimentaria No Especificado tipo Restrictivo (TCANE-R; n=21). Resultados: Se hallan como factores de riesgo de consistencia el antecedente de obesidad y el inicio del TCA en la adolescencia. El inicio de la menarquia en la edad temprana no resulta ser un factor de riesgo. El Índice de Masa Corporal (IMC) refleja la sintomatología alimentaria de cada cuadro diagnóstico. El grupo BN-P, se caracteriza por presentar mayor severidad en la sintomatología alimentaria. La mayoría de grupos presenta larga duración de la enfermedad, dificultades en la imagen corporal, el funcionamiento psicosocial y características de personalidad. El sentimiento de ineficacia no fue una característica clínica en casos de TA. Conclusiones: El que los antecedentes de obesidad se hayan mostrado como un factor de riesgo de consistencia en los TCA es un argumento más a favor de la necesidad de su prevención. Las dificultades en el funcionamiento psicosocial encontradas en casos clínicos con TA, avalarían la necesidad de líneas de intervención de tipo más interpersonal en este tipo de pacientes.

Method: Evalua [...] tion before intervention of 73 patients with Bulimia Nervosa Purging type (BN-P; n=29), Binge Eating Disorder (BED; n=6), Eating Disorders Not Otherwise Specified Purging type (EDNOS-P; n=17) and Eating Disorders Not Otherwise Specified Restrictive type (EDNOS-R; n=21). Findings: Consistent risk factors in the precedent of obesity and the beginning of the ED in adolescence. The young age at which menarche occurred was not a risk factor. The eating symptomatology of each diagnostic category reflected the nutritional state. The BN-P group presented a more severe eating symptomatology. The majority of the groups had long duration illness and had difficulties with body shape, social performance, and personality problems. The feeling of ineffectiveness was not a clinical characteristic in Binge eating cases. Conclusion: The precedent of obesity showed up as a consolidated risk factor in eating disorders, supporting the necessity of prevention. Difficulties found in social performance in binge eating support the necessity of interpersonal intervention.

  5. Factors Influencing HEPA Filter Performance

    International Nuclear Information System (INIS)

    Properly functioning HEPA air filtration systems depend on a variety of factors that start with the use of fully characterized challenge conditions for system design and then process control during operation. This paper addresses factors that should be considered during the design phase as well as operating parameters that can be monitored to ensure filter function and lifetime. HEPA filters used in nuclear applications are expected to meet design, fabrication, and performance requirements set forth in the ASME AG-1 standard. The DOE publication Nuclear Air Cleaning Handbook (NACH) is an additional guidance document for design and operation HEPA filter systems in DOE facilities. These two guidelines establish basic maximum operating parameters for temperature, maximum aerosol particle size, maximum particulate matter mass concentration, acceptable differential pressure range, and filter media velocity. Each of these parameters is discussed along with data linking variability of each parameter with filter function and lifetime. Temporal uncertainty associated with gas composition, temperature, and absolute pressure of the air flow can have a direct impact on the volumetric flow rate of the system with a corresponding impact on filter media velocity. Correlations between standard units of flow rate (standard meters per minute or cubic feet per minute) versus actual units of volumetric flow rate are shown for variations in relative humidity for a 70 deg. C to 200 deg. C ve humidity for a 70 deg. C to 200 deg. C temperature range as an example of gas composition that, uncorrected, will influence media velocity. The AG-1 standard establishes a 2.5 cm/s (5 feet per minute) ceiling for media velocities of nuclear grade HEPA filters. Data are presented that show the impact of media velocities from 2.0 to 4.0 cm/s media velocities (4 to 8 fpm) on differential pressure, filter efficiency, and filter lifetime. Data will also be presented correlating media velocity effects with two different particle size distributions. (authors)

    Full Text Available This study examined the role of internalization and comparison as mediators of relationships between socio-cultural pressures to be thin, psychological factors, restrictive and bulimic behaviours in college females. Participants were 262 Croatian college females (mean age = 21.22 ± 1.47 years who completed self-report questionnaires. Regression analysis was used to test a model in which internalization and social comparison mediated the impact of socio-cultural pressure (parents and peers dieting, teasing, pressure to be thin, media influences, self-esteem, anxiety, depression, and perfectionism in restrictive and bulimic behaviours. Internalization is a significant mediator of the relationships between all predictors included in this research and disturbed eating habits. Social comparison is relevant as a mediator between social influence, negative affect, self-esteem, perfectionism and restrictive behaviour but does not mediate bulimic behaviour. These findings could be seful in understanding processes that may predispose young women to develop eating dysfunctions and indicate the need for prevention programs that incorporate formative influences and processes such as internalization of societal norms and comparison in the construction of therapeutic strategies.

    2015-01-01

    Socio-affective difficulties, in particular difficulties in representing, communicating and feeling emotions, may play a critical role in anorexia nervosa (AN). The aim of this longitudinal study was to explore the links between alexithymia and two types of difficulties in AN: eating symptoms and social avoidance. Sixty adolescent girls with AN were recruited following hospitalisation in a specialised department. They completed self-administered questionnaires of alexithymia (TAS-20), of central symptoms of the eating disorders (EDI), and of anxious and depressive affects (SCL-90). Anxiety and social avoidance were assessed in the course of a standardised interview (LSAS). These measures were performed at inclusion, and at 6-, 12- and 18-months' follow-up. The relationship between TAS-20 and EDI or LSAS total scale scores across the four time points was assessed using mixed-effects models, including anxiety, depression, BMI, anorexia subtype, and age as co-factors. Partial least square regression was used to refine this multivariate analysis at subscale level, at inclusion and 18 months. Robust associations between TAS-20 and EDI scores were found, independently from anxious and depressive scores, nutritional state and AN subtype. These effects appeared more particularly linked to the implication of the dimensions difficulties identifying and describing feelings, interpersonal mistrust, feelings of inadequacy and interoceptive awareness deficit. There was also a durable association between alexithymia and social anxiety and avoidance, after adjusting for the confounding effects of depression, and anxiety, and the state of starvation. Difficulties in describing feelings appeared particularly involved here. Thus alexithymia does appear as a factor in the persistence of disorders in AN, and difficulties identifying and describing feelings could compound the social difficulties and major the relational isolation of these patients.

    The 'Fragebogen zum Essverhalten' (FEV) is the German version of the Three-factor-Eating-Questionnaire (TFEQ). This questionnaire covers three domains of eating behaviour ('cognitive restraint', 'disinhibition' and 'hunger') as well as common problems (e.g. craving for sweets). So far, there is a lack of normative data of the FEV especially for the middle-aged and older population. Aim of this study therefore was to provide age- and gender-specific norms of the FEV for the general population aged 40-79 years. We studied 3144 participants of the ongoing large community-based Leipzig Research Center for Civilization Diseases (LIFE) Health Care Study. We provided age- (four age groups: 40-49, 50-59, 60-69, and 70-79 years) and gender-specific percentile ranks and T-scores for the three domains of the FEV as well as age- and gender-specific frequencies of the common problems in eating behaviour. Females scored significantly higher than males in all three domains of the FEV (p?problems in eating. The main problem in both genders was craving for sweets (38.6%). Eating in response to stress was mostly reported in younger individuals. The present study offers current normative data for the FEV in the middle-aged and older general population that can be applied in clinical and non-clinical settings. Information on eating behaviour can be helpful in understanding body weight modulation, and thus, may help to improve interventive and preventive programmes for overweight, obesity, and eating disorders.

Abstract in english Eating disorders (TCA per its abbreviation in Spanish) are common in young women, with an estimated prevalence of 4-5%. One of the physical complications of eating disorders, especially anorexia nervosa (AN) and eating disorder not otherwise specified (TANE) is bone mass loss, which affects both cor [...] tical and trabecular bone. The synergistic effect of malnutrition and estrogen deficiency produces significant bone mass loss, resulting from the uncoupling of bone turnover characterized by a decrease in osteoblastic bone formation and an increase in osteclastic bone resorption.

Severity of bone loss in anorexia nervosa varies depending on duration of illness, the minimal weight ever and sedentarism or strenuous exercise. Long term consequences occur, such as a fracture risk increase in patients who have suffered anorexia nervosa, compared with the general population. The first treatment line to recover bone mass is nutritional rehabilitation together with weight gain. Hormonal replacement therapy may be effective if combined with an anabolic method. Osteopenia and osteoporosis are terms adopted to define the deficiency of bone mass in adults. Authors have used these terms to define densitometric data in young subjects who have not reached their peak bone mass. We suggest the term "hypo-osteogenesia" to define the deficiency in the development of bone mass in adolescents or children.

    2015-01-01

    This study examined the impact of regular supervised exercise on body fat, assessed via anthropometry, and eating patterns of peripheral arterial disease patients with intermittent claudication (IC). Body fat, eating patterns and walking ability were assessed in 11 healthy adults (Control) and age- and mass-matched IC patients undertaking usual care (n = 10; IC-Con) or supervised exercise (12-months; n = 10; IC-Ex). At entry, all groups exhibited similar body fat and eating patterns. Maximal walking ability was greatest for Control participants and similar for IC-Ex and IC-Con patients. Supervised exercise resulted in significantly greater improvements in maximal walking ability (IC-Ex 148%-170% vs. IC-Con 29%-52%) and smaller increases in body fat (IC-Ex -2.1%-1.4% vs. IC-Con 8.4%-10%). IC-Con patients exhibited significantly greater increases in body fat compared with Control at follow-up (8.4%-10% vs. -0.6%-1.4%). Eating patterns were similar for all groups at follow-up. The current study demonstrated that regular, supervised exercise significantly improved maximal walking ability and minimised increase in body fat amongst IC patients without changes in eating patterns. The study supports the use of supervised exercise to minimize cardiovascular risk amongst IC patients. Further studies are needed to examine the additional value of other lifestyle interventions such as diet modification. PMID:25993298

    To test hypotheses that women suffering from some form of eating disorder would experience lower self-esteem and higher depression and that women with lower self-esteem and greater depression would rate their attractiveness lower and see themselves as heavier than less depressed individuals, 42 college undergraduate women were individually administered the Eating Disorders Inventory, Beck Depression Inventory, Coopersmith Self-esteem Inventory, and a Body Image/Attractiveness Perception Scale. A Pearson correlation indicated a substantial relation between scores on depression and scores on eating disorders, but nonsignificant values between self-esteem scores and scores on either eating disorders or on depression. Depression scores correlated significantly with rated body size, but not attractiveness, while self-esteem scores were significantly correlated with rated attractiveness, not body size. These results contradict literature on the relation between self-esteem and depression. Directions for additional research are discussed. PMID:8332667

SAFA was administered to a cohort of 97 patients, aged from 8.8 to 18, with an ED diagnosis. Age, body mass index (BMI and BMI standard deviation score were analyzed. Furthermore, while looking for linkable risk factors, we evaluated other data that took an influence over the SAFA profile, like parental separation and family components’ number. Compared to the range of statistical normality (based on Italian population, patients with bulimia nervosa or binge-eating disorder showed higher and pathologic values in specific subscales. When analyzing sex, males showed more pathologic values in most anxiety-related, obsessiveness–compulsiveness-related and insecurity subscales. A correlation among age, BMI and specific subscales (low self esteem, psychological aspects emerged in participants with anorexia nervosa. In order to plan more appropriate diagnostic and therapeutic approaches in children or adolescents suffering from ED, the SAFA test can be an important instrument to evaluate psychiatric symptoms. Therefore, we propose to include this useful, simple self-administered test as a new screening tool for ED diagnosis.

  7. A review of factors influencing litter size in Irish sows

    2007-06-01

    Full Text Available Abstract Many factors influence litter size. These include genetics, gilt management, lactation length, parity distribution, disease, stress and boar fertility. In the past 20 years, litter size in Irish sows has increased by only one pig. Born alive figures now average at 11.2 pigs per litter. In this regard, Ireland is falling behind our European competitors who have made significant advances over this time. Denmark, for example, has an average figure of 12.7 pigs born alive per litter and France an average of 12.5. The single area that could be improved immediately is sow feeding. It is important that sows are fed correctly throughout pregnancy. If over-fed during pregnancy, sows will have depressed appetite during lactation. If underfed in pregnancy, sows will be too thin at farrowing. The correct way to feed a pregnant sow is to match her feed allocation to her requirement for maintenance, body growth and growth of her developing foetuses. During lactation, sows should be given as much feed as they can eat to prevent excessive loss of body condition. Liquid-feed curves should be such that lactating sows are provided with a minimum mean daily feed supply of 6.2 kg. A small proportion of sows will eat more and this could be given as supplementary dry feed. Where dry feeding is practised in the farrowing house, it is difficult to hand-feed sows to match their appetite. Ideally ad libitum wet/dry feeders should be used. From weaning to service, sows should once again be fed ad libitum. If liquid feeding, this means giving at least 60 MJ DE (digestible energy per day during this period. If dry feeding, at least 4 kg of lactation diet should be fed daily. The effort spent perfecting sow feeding management on units should yield high dividends in the form of increased pigs born alive per litter.

    The objective was to explore what predicts first-year college women's disordered eating tendencies when they arrive on campus. The 215 first-year college women completed the surveys within the first 2weeks of classes. A structural model examined how much the Helplessness, Hopelessness, Haplessness Scale, the Brief COPE, the Brief College Student Hassle Scale, and the Body Shape Questionnaire predicted eating disordered tendencies (as measured by the Eating Attitudes Test). The Body Shape Questionnaire, the Helplessness, Hopelessness, Haplessness Scale (inversely), and the Denial subscale of the Brief COPE significantly predicted eating disorder tendencies in first-year college women. In addition, the Planning and Self-Blame subscales of the Brief COPE and the Helplessness, Hopelessness, Haplessness Scale predicted the Body Shape Questionnaire. In general, higher levels on the Helplessness, Hopelessness, Haplessness Scale and higher levels on the Brief College Student Hassle Scale related to higher levels on the Brief COPE. Coping seems to remove the direct path from stress and depression to disordered eating and body dissatisfaction. PMID:25528718

    Full Text Available Abstract Background The lifestyle-related behaviors having breakfast, drinking sweet beverages, playing outside and watching TV have been indicated to have an association with childhood overweight, but research among young children (below 6?years old is limited. The aim of the present study was to assess the associations between these four behaviors and overweight among young children. Methods This cross-sectional study used baseline data on 5-year-old children (n?=?7505 collected for the study ‘Be active, eat right’. Age and sex-specific cut-off points for body mass index of the International Obesity Task Force were used to assess overweight/obesity. Multivariable logistic regression analyses were applied. Results For children whom had breakfast 2 hours/day, the odds ratio (OR for having overweight (obesity included was, respectively, 1.49 (95% confidence interval (CI: 1.13-1.95, and 1.25 (95% CI: 1.03-1.51. There was a positive association between the number of risk behaviors present and the risk for having overweight. For children with 3 or all of the risk behaviors having breakfast 2 glasses/day, playing outside 2 hs/day, the OR for overweight was 1.73 (95% CI: 1.11-2.71 (all models adjusted for children’s sex and sociodemographic characteristics. Conclusion Given the positive association between the number of behavioral risk factors and overweight, further studies are needed to evaluate the effectiveness of behavioral counseling of parents of toddlers in preventing childhood overweight. In the meantime we recommend physicians to target all four behaviors for counseling during well-child visits.

    Evidence suggests that adolescents' experience of binge eating (BE) might differ in important ways from that of adults. Moreover, although BE appears more common in African American women than other disordered eating behaviors, little is known about the influence of cultural factors on this behavior in adolescents. The current investigation used qualitative methodology to examine the perceptions of White and African American adolescent girls and their mothers regarding experiences of binge and loss of control eating. Five focus groups were completed with 19 adolescent girls (aged 13-17, 58 % African American, 41 % White) who endorsed loss of control eating behaviors. Their mothers (N = 19) also completed separate, concurrent focus groups addressing food and eating behaviors. Responses to focus group questions were analyzed using thematic qualitative analysis. Adolescents' awareness of their eating behaviors varied greatly. Girls reported some awareness of how emotions influence their eating behaviors, and described using food to achieve autonomy. Mothers evidenced awareness of their daughters' problematic eating behaviors, the effects of emotions on eating for both their daughters and themselves, and sociocultural factors influencing diet. Data from these focus groups can inform the development of innovative interventions for adolescent girls engaging in loss of control eating. PMID:25400491

    Factors that may have influenced aminoglycoside use and expenditure in one hospital were examined. Factors that were evaluated as to their influence on aminoglycoside-use patterns were: (1) formulary status; (2) bacterial susceptibility patterns; (3) identified or perceived differences in toxicity; (4) changes in patient population; (5) price paid by the hospital for aminoglycosides; (6) distribution of newsletters or memoranda; (7) advertising and detailing; and (8) pharmacy policies. For FY 1976-77 to 1979-80, the largest proportion of aminoglycoside expense was for gentamicin. During FY 1980-81, the expenditure for gentamicin decreased and tobramycin accounted for the largest proportion of total expenditure. Monthly gentamicin use decreased 20% during FY 1980-81 from the previous year. Tobramycin use increased from January 1979 to November 1980 and decreased from December 1980 to June 1981. Kanamycin use and amikacin use were fairly constant during the study period. Based on temporal relationships, the following factors appeared to influence aminoglycoside use and expenditure: (1) a study conducted at the institution from June 1977 to June 1979 comparing gentamicin and tobramycin nephrotoxicity; (2) a comparative nephrotoxicity study published in a widely circulated medical journal in May 1980; and (3) an intramural newsletter and memorandum distributed in March 1981 encouraging selective aminoglycoside use. The identification of factors that potentially influenced aminoglycoside use can be used to anticipate the future impact of similar events and to devise strategies to influence antimicrobial use.

    Full Text Available Bibliometric constructions of "knowledge maps" and "cognitive structures of science" do not differentiate between impact and influence factors. The difference can be constructedaccording to different meaning and interpretation of the terms reference and citation. Reference is "acknowledgment which one author gives to another", whereas citation is "acknowledgment which one document receives from another". Development of Information Science according to period and subject area is analyzed on the corpus of citation literature retrieved from doctoral dissertations in Information Science from 1978 to 2007 at Croatian universities. The research aim is to indicate the difference between document impact factor and author's influence factor (i.e. reference ability to produce effects on actions, behavior, and opinions of authors of doctoral theses. The influence factor serves to distinguish the key role of cited authors in time and according to the duration of the influence (the average age for cited papers of dominant authors in different periods is between eight and ten years. The difference between linear and interactive communication seems vital for the interpretation of cited half-life, i.e. the attitude of one science community towards used information resources and cognitive heritage. The analyzed corpus of 22,210 citations can be divided into three communication phases according to influence factor criteria: in the phase of dialogue and interactive communication 25% of bibliographic units are cited in the first four years; in the second phase another 25% of units are cited from the fifth to the ninth year; after ten years, in the dominant linear communication phase, approximately 30% of units are cited.

    Atria, Catherine Graczyk

    Females have been underrepresented in the study of science and science careers for decades although advancements have been made in closing this gender gap, the gap persists particularly in the physical sciences. Variables which influence a woman's desire to pursue and maintain a science course of study and career must be discovered. The United States lags behind other industrialized countries in the fields of science, math, and engineering. Females comprise an estimated half of the population; their potential contributions cannot be ignored or overlooked. This retrospective research study explores the personal experiences of ten women enrolled in science majors, with science related career plans. The goal of this study is to describe the factors that influence the participants' interest in science. The findings, the effect of science coursework, science teachers' personality and manner, other influential educational personnel, role models and mentors, external influences exclusive of school, parental influence, locus of control and positive attitudes toward science confirm what other researchers have found.

    The aims of this study were to analyze the psychometric properties of the Spanish version of the Three-Factor Eating Questionnaire-R18 (TFEQ-SP), as well as determine its validity by evaluating the relationship of the TFEQ-SP with different parameters related to body mass index, weight perception, perception of physical fitness, self-esteem, and food intake, as well as with weight control-related variables. A total of 281 participants (aged 18.38 ± 6.31) were studied. The factor analysis yielded three factors: cognitive restraint (CR), uncontrolled eating (UE), and emotional eating (EE). The internal consistency of the TFEQ-SP was determined by means of Cronbach's ? coefficient, with values ranging between 0.75 and 0.87. Higher scores on CR were found in women (p physical fitness (p physical fitness (p < 0.05). The validation study of the TFEQ-SP meets the requirements for measuring the three different facets of eating behavior: CR, UE, and EE. PMID:25486370

  11. Influence of organizational factors on safety

    International Nuclear Information System (INIS)

    There is a need for a better understanding of exactly how organizational management factors at a nuclear power plant (NPP) affect plant safety performance, either directly or indirectly, and how these factors might be observed, measured, and evaluated. The purpose of this research project is to respond to that need by developing a general methodology for characterizing these organizational and management factors, systematically collecting information on their status and integrating that information into various types of evaluative activities. Research to date has included the development of the Nuclear Organization and Management Analysis Concept (NOMAC) of a NPP, the identification of key organizational and management factors, and the identification of the methods for systematically measuring and analyzing the influence of these factors on performance. Most recently, two field studies, one at a fossil fuel plant and the other at a NPP, were conducted using the developed methodology. Results are presented from both studies highlighting the acceptability, practicality, and usefulness of the methods used to assess the influence of various organizational and management factors including culture, communication, decision-making, standardization, and oversight. 6 refs., 3 figs., 1 tab

    Sensory quality of pork is a complex phenotype determined by interactions between genetic and environmental factors. This study aimed at describing the respective influences of breed and production system on the development of pork quality. Plasma stress indicators and Longissimus muscle (LM) composition, physicochemical and sensory quality traits were determined in two contrasted breeds - the conventional Large White (LW, n=40) and the French local Basque (B, n=60). Pigs were reared in either a conventional (C; n=20 per breed), alternative (A; sawdust bedding and outdoor area, n=20 per breed) or extensive system (E; free-range, n=20 B). All the pigs from A and C systems were slaughtered at the same slaughterhouse, whereas B pigs from the E system were slaughtered at a local commercial abattoir. Major breed differences were found for almost all traits under study. LM from B pigs exhibited higher lipid, lower water and collagen concentrations, as well as lower collagen thermal solubility (P0.05) influence plasma stress indicators, LM chemical composition and physicochemical or sensory traits of pork. In contrast, within the B pigs, the E system affected the meat quality more. Lower plasma cortisol levels (Pmeat pH1 and pHu values and shear force (Pmeat, but did not impact the eating quality of pork. Altogether, this study demonstrates that differences in meat quality between B and LW breeds can be modulated by extensive pig production system. PMID:25908582

    Petrovich, Gorica D

    2011-09-26

    Appetite and eating are not only controlled by energy needs, but also by extrinsic factors that are not directly related to energy balance. Environmental signals that acquire motivational properties through associative learning-learned cues-can override homeostatic signals and stimulate eating in sated states, or inhibit eating in states of hunger. Such influences are important, as environmental factors are believed to contribute to the increased susceptibility to overeating and the rise in obesity in the developed world. Similarly, environmental and social factors contribute to the onset and maintenance of anorexia nervosa and other eating disorders through interactions with the individual genetic background. Nevertheless, how learning enables environmental signals to control feeding, and the underlying brain mechanisms are poorly understood. We developed two rodent models to study how learned cues are integrated with homeostatic signals within functional forebrain networks, and how these networks are modulated by experience. In one model, a cue previously paired with food when an animal was hungry induces eating in sated rats. In the other model, food-deprived rats inhibit feeding when presented with a cue that signals danger, a tone previously paired with footshocks. Here evidence will be reviewed that the forebrain network formed by the amygdala, lateral hypothalamus and medial prefrontal cortex mediates cue-driven feeding, while a parallel amygdalar circuitry mediates suppression of eating by the fear cue. Findings from the animal models may be relevant for understanding aspects of human appetite and eating, and maladaptive mechanisms that could lead to overeating and anorexia. PMID:21549730

  12. Factors influencing thermal tolerances of individual organisms

    International Nuclear Information System (INIS)

    The diversity of experimental methods and terminology employed by investigators to measure the effects of high temperatures on individual organisms, plus the often overlooked complexities of the holocoenotic environment, has often led to disconcerting conclusions. A plea is made for standardization of testing methods and for a wider appreciation of factors that may alter thermal tolerances. The influence of elevated temperature is grouped into three categories, lethal effects, controlling effects, and directive effects, all of which should be considered in assessing the impact of thermal effluent on organisms. In addition, the terminology (acclimation, acclimatization, adaptation, habituation, lethal temperature, critical thermal maximum, etc.) needs standardized definitions. The important factors influencing thermal effects on organisms include photoperiod, seasonal and daily cycles, geographic variation, diet, sex, breeding condition, age, life-cycle stage, salinity, chemicals, body water content and partitioning, oxygen supply, pH, innate and learned behavior, history of thermal exposure, sublethal exposure to limiting factors, and experimental methods. Examples of most of these are given to illustrate the role of temperature in the holocoenotic environmental complex of individual organisms

    2004-01-01

    Full Text Available Syneresis is the process of whey separation induced by gel contraction resulting in rearranging or restructuring of casein matrix formed during enzymatic coagulation. Numerous factors can influence the process of syneresis. The influences of pH, calcium concentration, temperature of coagulation of milk and applied heat treatment on the syneresis induced by different intensity of centrifugal force have been investigated. Coagulated samples were centrifuged at 1000, 2000 and 3000 rpm for 5 min, respectively. Reconstituted skim milk powder (control sample and reconstituted non-fat milk heat treated at 87ºC/10 min (experimental sample are coagulated at temperatures of 30ºC and 35ºC, at pH value of 5.8 and 6.2, and with the addition of 100, 200 and 400 mg/l of CaCl2, respectively. Centrifugation at 1000 rpm of both control and experimental samples didn’t recover any sera, regardless of the applied coagulation conditions. This indicates that the intensity of centrifugal force wasn’t strong enough to disrupt gel structure and cause syneresis. When the intensity of centrifugal force was increased up to 2000 rpm, the syneresis was induced, but the degree of syneresis depended on the applied factors of coagulation, primary on the applied heat treatments and temperature of coagulation. The amount of added CaCl2 didn’t have a significant influence on the induced syneresis at 2000 rpm. The induced syneresis was very significant for both control and experimental samples when the intensity of centrifugal force of 3000 rpm was applied. It was also noted that curd produced from heat treated milk in which milk protein coaggregates were formed, released less sera regardless of the applied coagulation factors.

  20. Predators' toxin burdens influence their strategic decisions to eat toxic prey.

    Science.gov (United States)

    Skelhorn, John; Rowe, Candy

    2007-09-01

    Toxic prey advertise their unprofitability to predators via conspicuous aposematic coloration [1]. It is widely accepted that avoidance learning by naive predators is fundamental in generating selection for aposematism [2, 3] and mimicry [4, 5] (where species share the same aposematic coloration), and consequently this cognitive process underpins current evolutionary theory [5, 6]. However, this is an oversimplistic view of predator cognition and decision making. We show that predators that have learned to avoid chemically defended prey continue to attack defended individuals at levels determined by their current toxin burden. European starlings learned to discriminate between sequentially presented defended and undefended mealworms with different color signals. Once birds had learned to avoid the defended prey at a stable asymptotic level, we experimentally increased their toxin burdens, which reduced the number of defended prey that they ingested in the subsequent trial. This was due to the birds making strategic decisions to ingest defended prey on the basis of their visual signals. Birds are clearly able to learn about the nutritional benefits and defensive costs of eating defended prey, and they regulate their intake according to their current physiological state. This raises new perspectives on the evolution of aposematism, mimicry, and defense chemistry. PMID:17716896

  2. Organizational factors influencing improvements in safety

    International Nuclear Information System (INIS)

    Research reported here seeks to identify the key organizational factors that influence safety-related performance indicators in nuclear power plants over time. It builds upon organizational factors identified in NUREG/CR-5437, and begins to develop a theory of safety-related performance and performance improvement based on economic and behavioral theories of the firm. Central to the theory are concepts of past performance, problem recognition, resource availability, resource allocation, and business strategies that focus attention. Variables which reflect those concepts are combined in statistical models and tested for their ability to explain scrams, safety system actuations, significant events, safety system failures, radiation exposure, and critical hours. Results show the performance indicators differ with respect to the sets of variables which serve as the best predictors of future performance, and past performance is the most consistent predictor of future performance

    Following factors possibly influencing the cardiac MIBG accumulation were examined mainly in mice. 1. The specific activity of the MIBG (meta-iodo-benzyl guanidine) on the neuronal and non-neuronal fractions. 2. Motor restriction stress on MIBG accumulation and washout. 3. Loading and restriction of sodium chloride on the accumulation and effect of suppression of renin-angiotensin system. 4. Examinations in Dahl rats. 125I- or 131I-MIBG was intravenously administered to mice at 74 kBq. At 30 min or 4 hr after administration, mice were sacrificed and their left ventricles were dissected out for measurement of radioactivity in a liquid scintillation counter. Salt-sensitive and -resistant Dahl rats were given with 37 MBq of 123I-MIBG and cardiac radioactivity was measured externally for calculation of washout. Factors examined were found highly correlated with the accumulation of MIBG and measurement of its washout was considered useful for evaluating sympathetic activity. (K.H.)

Our theoretical framework builds on social cognitive theory and the focus theory of normative conduct, and data are analysed by means of confirmatory factor analysis and structural equation modelling. The study reveals that when it comes to adolescents' fruit and vegetable intake, parents remain the main influencer, with what they do (descriptive norms) being more important than what they say (injunctive norms).

No previous studies have included all these factors in the same analysis. The study hasa number of important implications: (1) healthy eating interventions should aim at strengthening self-efficacy and positive outcome expectations among adolescents, (2) the family context should be included when implementing healthy eating interventions and (3) parents' awareness of their influence on children's healthy eating should be reinforced.

    Coral reefs face a crisis due to local and global anthropogenic stressors. A large proportion of the ~50% coral loss on the Great Barrier Reef has been attributed to outbreaks of the crown-of-thorns-seastar (COTS). A widely assumed cause of primary COTS outbreaks is increased larval survivorship due to higher food availability, linked with anthropogenic runoff . Our experiment using a range of algal food concentrations at three temperatures representing present day average and predicted future increases, demonstrated a strong influence of food concentration on development is modulated by temperature. A 2°C increase in temperature led to a 4.2-4.9 times (at Day 10) or 1.2-1.8 times (Day 17) increase in late development larvae. A model indicated that food was the main driver, but that temperature was an important modulator of development. For instance, at 5000?cells ml(-1) food, a 2°C increase may shorten developmental time by 30% and may increase the probability of survival by 240%. The main contribution of temperature is to 'push' well-fed larvae faster to settlement. We conclude that warmer sea temperature is an important co-factor promoting COTS outbreaks. PMID:25672480

    Emotional eating has a female preponderance and an understanding of possible genetic and environmental underpinnings is still in the early stages. The current study focuses on the possible role of the dopamine D4 receptor (DRD4) 'plasticity' gene in emotional eating and the possible moderator effects of sex and season of birth therein. We tested this in two samples (n?=?93 and n?=?586) of male and female Caucasian adults by genotyping DRD4 and assessing self-reported emotional eating. Participants were defined as high risk carriers if they had at least one long (7-repeat) allele, which confers hypo-function to DRD4. We also ran analyses that grouped 2- and 7-repeat carriers together. In the first sample there only was a moderator effect of sex. In the second sample there also was a 3 way interaction between season of birth, sex and genotype. In line with the idea that the Drd4 gene functions as a plasticity gene that affects the sensitivity to environmental influences, the moderator effect of sex was only found for the participants born in fall. Only in females the hypo-functional variants of DRD4 were associated with significantly higher degrees of emotional eating. Furthermore, the sex?×?genotype effects were somewhat stronger when the 2-repeat allele was grouped together with the 7-repeat allele. Our data suggest that DRD4 hypo-functional genetic variants are associated with emotional eating, only in females. PMID:25736807

    Full Text Available The aims of this study were to analyze the psychometric properties of the Spanish version of the Three-Factor Eating Questionnaire-R18 (TFEQ-SP, as well as determine its validity by evaluating the relationship of the TFEQ-SP with different parameters related to body mass index, weight perception, perception of physical fitness, self-esteem, and food intake, as well as with weight control-related variables. A total of 281 participants (aged 18.38 ± 6.31 were studied. The factor analysis yielded three factors: cognitive restraint (CR, uncontrolled eating (UE, and emotional eating (EE. The internal consistency of the TFEQ-SP was determined by means of Cronbach’s ? coefficient, with values ranging between 0.75 and 0.87. Higher scores on CR were found in women (p < 0.5, overweight/obese participants (p < 0.001, participants with lower self-esteem (p < 0.05, participants who overestimated their weight (p < 0.001, participants who weighed themselves frequently (p < 0.001 and those who were about to go on a diet (p < 0.001. Higher EE scores were found in participants with lower self-esteem scores (p < 0.05, among participants with a poorer perception of their physical fitness (p < 0.01 and when participants were about to diet (p < 0.05. Higher scores on UE were observed in case of poorer perception of physical fitness (p < 0.05. The validation study of the TFEQ-SP meets the requirements for measuring the three different facets of eating behavior: CR, UE, and EE.

    Full Text Available STUDY AIM: To determine which models are used by occupational therapists who attended a workshop on the Kawa Model, in their practice, the demographic factors related to the use of these models and the reasons why they use various models in their practice. METHOD: A descriptive, single case study me [...] thod was used with embedded units. The research instrument consisted of a survey questionnaire with closed and some semi-structured questions. RESULTS: The characteristics of therapists influenced their use of models. This was determined by their educational background, their level of experience and exposure in the clinical field and their work setting. Time constraints and the nature of the presenting clients also played a role. The clinicians' overall attitude towards new theory and their habituated ways were highlighted as constant factors influencing model use. The use of models provides structure and assists occupational therapists to produce proper, profession-specific, scientifically-based intervention. Models taught during undergraduate studies need to be relevant to address clients' needs in their specific context.

Esa es la razón por la que los programas de prevención e interven [...] ción son tan importantes. Para desarrollar tales programas es necesario identificar los factores de riesgo relevantes que contribuyen a la aparición de este trastorno. En la presente investigación se analizan variables sociales relacionadas con el riesgo a desarrollar trastornos de la conducta alimentaria (comparaciones sociales, actitudes socioculturales sobre la apariencia y la ansiedad social) en una muestra no clínica de 375 mujeres. Los resultados muestran que la comparación social está directa e indirectamente (a través de la ansiedad social) relacionada de forma positiva con el riesgo para desarrollar trastornos de la conducta alimentaria, mientras que las actitudes socioculturales sobre la apariencia lo hace de forma indirecta (a través de la ansiedad social) y positiva con los problemas de la conducta alimentaria. Finalmente, se discute la importancia de incluir estas variables sociales en los programas de prevención e intervención.

That is the reason why prevention and intervention programs are so important. To develop these types of programs it [...] is necessary to identify relevant risk factors contributing to this disorder. In the current research social risk variables to develop eating disorders (social comparisons, sociocultural attitudes toward appearance and social anxiety) have been measured in a 375 women non clinical sample. Results have shown that social comparisons are direct and indirect (trough social anxiety) positively related with the risk to develop eating disorders and that sociocultural attitudes toward appearance are just indirect (trough social anxiety) and positively related to eating disorders. Finally, the importance of including these social variables in prevention and intervention programs is discussed.

    Full Text Available Background: Well-known fact is that the good surgical treatment, leaving only small residuals of thyroid tissue, is the outmost valid predictive factor of successful ablative radioiodine treatment. Assuming that all patients had state of the art surgical treatment, with this study we tried to evaluate other possible predictive factors of successful radioiodine therapy after total thyroidectomy. Methods: Total of 56 patients (15 males and 41 females mean age 43.37±13, operated during the year 2001 was evaluated. Due to differentiated carcinoma of the thyroid total thyreoidectomy was done in 7 with follicular and in 49 patients with papillary cancer. Forty-one patients received ablative 131 I dose (3.7GBq and fifteen patients received therapeutic dose (5.55GBq of radioiodine therapy. As possible predictive factors the TNM classification (T1, 6; T2, 17; T3, 4; T4, 28 and 24 with N0 and 32 with N1, the number of foci on whole body scan (WBS, and the serum level of thyroglobulin were statistically evaluated. One year after radioiodine therapy control WBS was done and successful outcome of the therapy was considered to be the WBS without visible accumulation of radioiodine and with low serum level of thyroglobulin. Results: Outcome of ablative radioiodine therapy was considered as successful in 55.4% patients and 44.6% of patients needed additional radioiodine therapies. Only the number of foci and the level of thyroglobulin showed statistically significant (p(0.05 influence on the outcome of applied radioiodine therapy. Conclusion: Significant influence of the thyroglobulin level and number of foci on the WBS in patients with total thyroidectomy could be explained by the fact that there were the signs of minimum thyroid residual tissue, and that there were no microscopic spread of disease.

    Full Text Available Teaching and learning a foreign language is a social process which requires theinteraction of two important parts of the process, the teacher and the students, in a socialenvironment. As this process takes place in a social context, it is inevitable toexperience some problems while teaching the students having different needs, interestsand levels. These problems may be caused by the students, teachers as well as thephysical environment in which teaching and learning take place. It is clear that languageteaching skill is not enough to handle these problems; teachers also need classroommanagement skills so that they are able to manage their classrooms. It is believed thatsuccessful classroom management is highly related to effective instruction. Asclassroom management is a general term that is affected by many factors, theeffectiveness of classroom environment depends on how teachers cope with thesefactors and provide their students with a positive and friendly classroom atmosphere. Itis clear that a detailed analysis of the factors that affect successful classroommanagement and adequate teacher training on how to cope with them will makeunmanageable classrooms manageable which will immediately result in effectiveteaching and learning process. In this article, factors that influence successful classroommanagement will be analyzed and possible solutions to these problems will bepresented.

    The degree to which media contributes to body dissatisfaction, life satisfaction and eating disorder symptoms in teenage girls continues to be debated. The current study examines television, social media and peer competition influences on body dissatisfaction, eating disorder symptoms and life satisfaction in a sample of 237 mostly Hispanic girls. 101 of these girls were reassessed in a later 6-month follow-up. Neither television exposure to thin ideal media nor social media predicted negative outcomes either concurrently nor prospectively with the exception of a small concurrent correlation between social media use and life satisfaction. Social media use was found to contribute to later peer competition in prospective analysis, however, suggesting potential indirect but not direct effects on body related outcomes. Peer competition proved to be a moderate strong predictor of negative outcomes both concurrently and prospectively. It is concluded that the negative influences of social comparison are focused on peers rather than television or social media exposure. PMID:23344652

    Abstract Background The literature reveals that structured education programmes, such as DAFNE, result in many positive outcomes for people with Type 1 diabetes including a decrease in HbA1c levels and reductions in hypoglycaemia. While there is evidence that some of these outcomes are maintained we do not know at present what factors are most important over time. The study aim was to identify the key factors impacting on persons with Type 1 diabetes ability to assimilate the Dose Adjustment For Normal Eating (DAFNE) DAFNE principles into their daily lives and how these factors change over time. Methods This is a longitudinal descriptive qualitative study. Interviews were undertaken with 40 participants who had attended DAFNE in one of 5 study sites across the Island of Ireland, at 6 weeks, 6 and 12 months after completion of the programme. The interviews lasted from 30 to 60 minutes and were transcribed verbatim. Data were analysed in three ways, a within time analysis, a cross sectional analysis for each participant and a thematic analysis which focused on examining changes over time Results Four themes that influenced participants\\' ability to assimilate DAFNE into their daily lives over time were identified. These were: embedded knowledge, continued responsive support, enduring motivation and being empowered. Support at the 6 month period was found to be crucial to continued motivation. Conclusions Understanding the factors that influence people\\'s ability to assimilate DAFNE principles over time into their daily lives can help health professionals give focused responsive support that helps people with diabetes become more empowered. Understanding that continued support matters, particularly around 6 months, is important as health professionals can influence good management by providing appropriate support and enhancing motivation.

    To maximize the efficiency of manufasture of smokeless fuel briquettes from blends of high-rank coals and pitches, it is necessary to optimize feedstock selection to maintain strength during carbonization and subsequent handling. From an understanding of carbonization behaviour of feedstock components and of microcarbonization phenomena at interfaces, the contribution of interfacial interactions to strength properties of briquettes is assessed. The crushing strength, microstrength and optical texture of briquettes from a range of feedstocks were determined before and after carbonization at 970 K. These techniques promoted understanding of the carbonization behaviour of blends of feedstocks and strength-structure relations in resultant briquettes. Factors of feedstock selection that influenced the strength of carbonized briquettes were identified. 19 refs., 7 tabs.

    Eating disorders appear with relative frequency in sports, such as gymnastics, figure skating or resistance sports, in which weight control is important. Their incidence is greater in women, frequently appearing a low self-esteem, a distorted body image in which the body is perceived with an excess of weight, inefficiency, perfectionism and a sense of control loss, with compensatory attempts exerted through food manipulation and the use of inadequate methods of control weight. Frequently, they are associated in female athletes to irregularities of the menstrual cycle, reduction of the bone mineral density and osteoporosis, giving rise to so-called female athlete triad. Cardiovascular problems, a greater incidence of fractures, and muscular power and resistance losses which impair performance, can also develop. Between the risk for their appearance are attempts to lose weight, often by recommendation of the coach, increases of training loads associated to weight losses, characteristics of the personality that take to excessive preoccupation by body image, or injuries and traumatisms. Treatment requires a multidisciplinary approach, with participation of physicians, psychologists/psychiatrists, nutricionists, coaches and family, being specially important the emphasis on preventive measures.

    2011-08-01

    Full Text Available Abstract Background Despite identical genotypes and seemingly uniform environments, stochastic gene expression and other dynamic intracellular processes can produce considerable phenotypic diversity within clonal microbes. One trait that provides a good model to explore the molecular basis of stochastic variation is the timing of host lysis by bacteriophage (phage. Results Individual lysis events of thermally-inducible ? lysogens were observed using a temperature-controlled perfusion chamber mounted on an inverted microscope. Both mean lysis time (MLT and its associated standard deviation (SD were estimated. Using the SD as a measure of lysis time stochasticity, we showed that lysogenic cells in controlled environments varied widely in lysis times, and that the level of lysis time stochasticity depended on allelic variation in the holin sequence, late promoter (pR' activity, and host growth rate. In general, the MLT was positively correlated with the SD. Both lower pR' activities and lower host growth rates resulted in larger SDs. Results from premature lysis, induced by adding KCN at different time points after lysogen induction, showed a negative correlation between the timing of KCN addition and lysis time stochasticity. Conclusions Taken together with results published by others, we conclude that a large fraction of ? lysis time stochasticity is the result of random events following the expression and diffusion of the holin protein. Consequently, factors influencing the timing of reaching critical holin concentrations in the cell membrane, such as holin production rate, strongly influence the mean lysis time and the lysis time stochasticity.

    Full Text Available Norbert Dahmen, Julia Becht, Alice Engel, Monika Thommes, Peter TonnPsychiatry Department, University of Mainz, GermanyAbstract: Narcoleptic patients suffer frequently from obesity and type II diabetes. Most patients show a deficit in the energy balance regulating orexinergic system. Nevertheless, it is not known, why narcoleptic patients tend to be obese. We examined 116 narcoleptic patients and 80 controls with the structured interview for anorectic and bulimic eating disorders (SIAB to test the hypothesis that typical or atypical eating attacks or eating disorders may be more frequent in narcoleptic patients. No difference in the current prevalence of eating disorders bulimia nervosa, binge eating disorder, or anorexia nervosa was found, nor was the frequency of eating attacks higher in the narcolepsy group. We conclude that present eating disorders and eating attacks as defined in DSM IV are not the reason for the observed differences in body composition. Additional factors, such as basal metabolic rates and lifestyle factors need to be considered.Keywords: narcolepsy, eating disorder, SIAB, bulimia, anorexia, eating attack

    Full Text Available Introducción: Rara vez se ha evaluado la efectividad de las campañas e intervenciones de información pública. Por ello, el estudio de actividades exitosas podría contribuir al desarrollo y puesta en práctica en el futuro de campañas e intervenciones a favor de una alimentación saludable Objetivos: El objetivo del presente estudio de campañas de información sobre alimentación saludable fue primeramente la identificación de los factores de éxito de las mismas, y seguidamente la descripción de sus inter-relaciones. Métodos: Se entrevistaron a 11 representantes de industrias alimentarias cuyas campañas fueron identificadas como exitosas en una etapa previa del estudio. Las entrevistas fueron luego analizadas con respecto a los factores de éxito potenciales. Estos últimos fueron posteriormente utilizados para desarrollar un modelo de factores de éxito y sus interrelaciones. Resultados: El éxito de los casos estudiados fue atribuido primeramente a las características del ambiente macro, o a una colaboración entre los sectores público y privado. Segundo, se identificó al compromiso de las comunidades, elementos de empoderamiento del grupo objetivo y a la ejecución de medidas de marketing social. Tercero, el éxito puede atribuirse a la adopción por parte de la ciudadanía de las campañas y los cambios estructurales consecuentes. Conclusiones: El modelo y los factores de éxito identificados resaltan que el éxito puede originarse en tres fases cruciales, el diseño y montaje de la campaña, su ejecución y finalmente, su interacción con la ciudadanía. El modelo puede servir como guía para el desarrollo de campañas en el futuro.Introduction: Public campaigns and interventions are rarely fully evaluated regarding their effectiveness. The analysis of past, successful activities can contribute to the future development of public campaigns and interventions for healthier eating. Objectives: The study of public campaigns and interventions for healthier eating aimed at identifying the underlying success factors and describing their relation. Methods: Interviews were conducted with representatives of 11 cases that had been identified as especially successful in an earlier research step. The interviews were analysed with regard to possible success factors and the latter used to develop a model of success factor interrelation. Results: It was found that success of the cases was first, attributed to characteristics of the macro environment or to public private partnerships in the initiation of campaigns, second, to the engagement of social communities, elements of empowerment of the target group and the implementation of social marketing measures, and thirdly, in citizens adoption of the campaign and in accompanying structural changes. Conclusions: The model and identified success factors underline that success can stem from three crucial phases: the set up of a campaign, the conduction and finally, the interrelation with the citizen. The model can serve as a guide in the future development of campaigns.

    Full Text Available Backgrounds: The prevalence of disordered eating behaviors has been reported to increase in recent decades; therefore, scientific studies should perform for specifying psychological variables that may contribute to the etiology of this disorder. In this study, we examined the role of body image disturbance and perfectionism variables in predicting disordered eating behaviors among female students.Materials and Methods: This cross-sectional study was performed in 2014 upon a sample consisting of 464 female students in Allame Tabatabaie University were selected based on a Morgan formula and multi-stage cluster random sampling. Then, participants responded to the questionnaires of body image disturbance of Reas and et al. (2002, perfectionism scale of Besharat (2004 and eating attitudes test of Garner and Garfinkel (1979. The data were analyzed by correlation techniques and stepwise regression.Results: The results showed that these were internal correlation among body image disturbance and perfectionism and disordered eating behavior. Also, the results of stepwise regression analysis revealed that body image disturbance and perfectionism significantly predicted, respectively, almost 16% and 14% of variances of disordered eating behaviors among female students.Conclusion: According to the findings of the present study, body image disturbance and perfectionism can predict disordered eating behaviors. Therefore, considering these variables can be important to prevent the development of eating-related diseases and to promote students’ health.

  10. Factors influencing induction of adaptive response

    International Nuclear Information System (INIS)

    Exposure to low doses of X-rays makes ICR mice resistant to subsequent sublethal irradiation and decrease mortality from hematopoietic death. Many factors, however, influence the induction of radioresistance. For instances, in ICR mice, the priming irradiation with 0.50 Gy was effective in the induction of radioresistance, when it is given at 6-week old, 2 weeks prior to subsequent sublethal irradiation. One hundred-fifty kV X-ray filtered off the soft component through 1.0 mm aluminum and 0.2 mm copper induces radioadaptive response as well as the harder radiation such as 260 kV X-ray filtered through 0.5 mm aluminum and 0.3 mm copper. Dose rate of priming irradiation also seemed to influence the induction of radioresistance. Priming irradiation with 0.50 Gy at 0.50 Gy/min and 0.25 Gy/min induced adaptive response, while same 0.50 Gy given at 0.063 Gy/min didn't. To make the matter complicated, when mice were pre-irradiated with 0.50 Gy at 0.013 Gy/min in the irradiation cell which was 1.2 x 1.2 x 1.4 times larger than the usual one, adaptive response was induced again. These results suggested that mice felt more uncomfortable when they were packing in the irradiation cell with little free space even for several minutes than when they were placed in the cell with much free space for about 40 minutes, and such a stress might give the mice some resistance to the subsequent sublethal irradiation.

  12. Factors Driving Biofuel Crops' Influence on Climate

    2010-12-01

    Large scale deployment of new biofuel crops has the potential to influence climate through biogeophysical and biogeochemical mechanisms operating at the land surface. In turn, climatic variability influences the productivity of biofuel crops and thus their potential contribution as a source of energy. In order to characterize this two-way interaction between biofuels and climate, we are conducting a series of modeling experiments within the National Center for Atmospheric Research (NCAR) Community Earth System Model (CESM). Key questions that this study attempts to address include 1) In what ways (e.g. at what spatial and temporal scales, under what land cover and management scenarios) does a transition to biofuel crops represent a climate stabilizing versus a climate destabilizing endeavor? 2) Which vegetation properties and management choices are most influential in determining key climatic outcomes associated with biofuels? 3) Are biofuel crop yields robust to changing climatic conditions? Our approach is to develop new biofuel plant functional types (PFTs) for the land surface component of CESM - the Community Land Model (CLM) - and to examine climatic implications of future biofuel deployment scenarios within the coupled land-atmosphere framework of CESM. We are focusing initially on c4 grass crops - i.e. switchgrass, miscnathus, sugarcane, and maize. CLM represents plant functional types with more than 50 parameters that describe aerodynamic, physiological, optical, and biogeochemical properties etc. We are also making structural modification to the model in order to represent unique features of biofuel crops and their management, such as changes to the phenology and carbon allocation schema for c4 grasses. Detailed observational data from new biofuel crops such as switchgrass and miscanthus is limited and offers a weak constraint on the full set of PFT parameters. To address this problem, we are conducting systematic sensitivity analysis on the default c4 grass parameters in CLM in order to identify a smaller set of parameters that exerts the most control on climatically relevant terms such as energy and carbon fluxes. By revealing those parameters that are most and least influential in terms of climate forcing, systematic sensitivity analysis helps to prioritize the search for observational data, constrains the process of tuning parameters to limited data, and leads the way to characterizing the uncertainty in biofuel crops’ influence on climate. Furthermore, due to similarities across managed ecosystems, these results offer general insight into those plant physiological properties and management factors that must be well-characterized in order to model changes in energy and carbon fluxes resulting from human land use.

El análisis de regresión mostró que la Preocupación por los Errores (PE) y la Indecisión de Acción explicaron la IC y la ISMD en BN; mientras que PE solo explicó la ISMD en TANE. Se concluye que solo dos componentes del perfeccionismo explican significativamente la interiorización del ideal de delgadez y la IC, las cuales son consideradas factores de riesgo importantes para los TCA. Abstract in english The purpose of this study was to assess if perfectionism components explained body dissatisfaction (BD), sociocultural influences of aesthetic model (SIAM) and symptoms of eating disorders (ED). The sample comprised 30 women with Bulimia Nervosa (BN), 35 women with Eating Disorder not Otherwise Spec [...] ified (EDNOS) and 63 women without ED. A regression analysis showed that concern over mistakes (CM) and doubt about actions explained BD and SIAM in the BN sample; while concern over mistakes only explained SIAM in the EDNOS sample. These findings evidence that two perfectionism components contribute to vulnerability of thinness ideal and BD among women, which constitute two important risk factors for ED.

    Eating disorders are multifactorial conditions that can involve a combination of genetic, metabolic, environmental, and behavioral factors. Studies in humans and laboratory animals show that eating can also be regulated by factors unrelated to metabolic control. Several studies suggest a link between stress, access to highly palatable food, and eating disorders. Eating “comfort foods” in response to a negative emotional state, for example, suggests that some individuals overeat to self-me...

    Full Text Available The study of factors influencing competitive anxiety, according to a multidimensional perspective and supported by valid instruments, is scarce among Brazilian athletes of different sports. The present study aims to: i investigate the theoretical relationship between the different dimensions of the multidimensional theory of anxiety (i.e., cognitive anxiety, somatic anxiety and self-confidence; and ii investigate the effects of gender, type of sport (individual or collective and competitive experience levels on cognitive anxiety, somatic anxiety and self-confidence. A total of 303 athletes (233 males and 70 females, from different sports, aged between 18 and 40 years (M =24.22, SD = 5.07 completed a shortened version of CSAI-2 (i.e., CSAI-2R, about one hour before the start of competitions. Results revealed significant correlations between cognitive anxiety, somatic anxiety and self-confidence dimensions, in accordance with the assumptions of the multidimensional theory. Additionally, comparative analyses indicated that female athletes and athletes from collective sports showed higher levels of cognitive anxiety, while male athletes and athletes with high competitive experience reported higher levels of self-confidence. These results were discussed taking into account the theoretical and practical implications of these findings for planning interventions of sport psychology in Brazil with athletes of different contexts.

  17. Influence of the PROP bitter taste phenotype and eating attitudes on energy intake and weight status in pre-adolescents: a 6-year follow-up study.

    The PROP bitter-taste phenotype is a marker for food preferences and eating behavior, and may associate with differences in body weight in children. Previous work has shown that PROP status in combination with eating attitudes are better predictors of weight status in preadolescents, than either factor alone. However, no studies have examined the role of PROP phenotypes in body weight change in children over time. The primary objective of this study was to investigate current weight status and change in weight status in children from preschool (baseline) to preadolescence as a function of eating attitudes and PROP phenotype. Other measures included self-reported food intakes and physical activity by activity monitor. Seventy-three lean (BMI percentile=57.7±3.2%) children with mean age=10.3±0.5yrs, participated in the follow up. There were no group differences in energy intake, current BMI-percentile or change in BMI percentile from baseline by PROP phenotype in either boys or girls. However, there was a trend for non-taster girls to show a downward shift in BMI-percentile at follow up. Hierarchical regression analysis revealed that baseline BMI percentile and physical activity energy expenditure were the strongest predictors of current weight (28.5% variance),followed by child restraint, the taster×gender interaction, and the maternal BMI×maternal emotional eating interaction, accounting for 7.1%, 6.0% and 4.8% of variance in the model, respectively. These findings suggest that PROP status and eating attitudes are modest predictors of weight status in preadolescent children. PMID:23680431

Método: El pronóstico de interés fue definido por la variable de remisión y recuperación. Para el análisis del estudio se realizaron una serie de regresiones logísticas. Resultado: Baja estima personal, y una menor patología en la función interpersonal fueron los factores de peor pronóstico. Conclusión: Aunque la terapia interpersonal es un tratamiento efectivo para las personas que sufren de bulimia nerviosa, los pacientes con estas patologías con baja estima personal y menos problemas interpersonales deberían de ser tratados con otro tipo de terapia.

Patients were assessed using a validated semi-structure interview (Clinical Eating Disorders Rating Instrument-CEDRIC) and completed measures of self-esteem (Rosenberg Self-esteem Scale-RSE), eating psychopathology (Eating Disorders Examination Questionnaire-EDE-Q), interpersonal functioning (Inventory of Interpersonal Functioning- IIP-32), and depression (Beck Depression Inventory-BDI). Method: Remission and recovery after 16 sessions of IPT were the two outcomes of interest. Univariate analysis and a series of backwards stepping logistic regressions were performed to determine the variables associated with remission and recovery. Result: Low self-esteem and less interpersonal problems were the main predictors of poor outcome. Conclusion: As patients with Bulimic Disorders with low levels of interpersonal problems and high levels of low self-esteem are likely to do less well with IPT, different type of treatment should be offered to them. A randomized controlled trial could explore this hypothesis in more detail.

    2015-03-01

    A major determinant of human eating behavior is social modeling, whereby people use others' eating as a guide for what and how much to eat. We review the experimental studies that have independently manipulated the eating behavior of a social referent (either through a live confederate or remotely) and measured either food choice or intake. Sixty-nine eligible experiments (with over 5800 participants) were identified that were published between 1974 and 2014. Speaking to the robustness of the modeling phenomenon, 64 of these studies have found a statistically significant modeling effect, despite substantial diversity in methodology, food type, social context and participant demographics. In reviewing the key findings from these studies, we conclude that there is limited evidence for a moderating effect of hunger, personality, age, weight or the presence of others (i.e., where the confederate is live vs. remote). There is inconclusive evidence for whether sex, attention, impulsivity and eating goals moderate modeling, and for whether modeling of food choice is as strong as modeling of food intake. Effects with substantial evidence were: modeling is increased when individuals desire to affiliate with the model, or perceive themselves to be similar to the model; modeling is attenuated (but still significant) for healthy-snack foods and meals such as breakfast and lunch, and modeling is at least partially mediated through behavioral mimicry, which occurs without conscious awareness. We discuss evidence suggesting that modeling is motivated by goals of both affiliation and uncertainty-reduction, and outline how these might be theoretically integrated. Finally, we argue for the importance of taking modeling beyond the laboratory and bringing it to bear on the important societal challenges of obesity and disordered eating. PMID:25174571

    International Nuclear Information System (INIS)

    The influence factors of dynamic adsorption of noble gases in activated carbon is discussed in this paper. The influence of flow rate in a certain range and of CO2 concentration in normal environment may be ignored. Dynamic absorption coefficient increases with the increase in system pressure and decreases with the increase in temperature and relative humidity. Water content in activated carbon is practically used as an influence factor instead of relative humidity in the condition of unbalanced adsorption. (authors)

  6. Factors influencing zinc bioavailability in rats

    International Nuclear Information System (INIS)

    The amount of Zn fed, its source, and the Zn status of experimental animals may affect Zn bioavailability. To test this, rats were fed doses of Zn from ZnCl2 or from various foods labeled extrinsically. Three weeks before and after the test meal, rats were fed an AIN diet modified in Zn content. Absorption was calculated by monitoring whole body retention and extrapolating to zero time. In rats fed 12 ppm Zn and test doses of 6 to 275 ?g, absorption decreased from 80 to 50%, and the amount absorbed increased quadratically (r2 = 0.998), but turnover was unaffected. Rats fed 38 or 77 ppm Zn absorbed less of test doses of 290, 613, or 1700 ?g Zn than did those fed 12 ppm, and their Zn turnover rate was higher. In two 2 x 7 factorial experiments, rats fed 12 or 38 ppm Zn were given 16 or 98 ?g Zn from 7 Zn sources. Bioavailability from some foods was higher than from ZnCl2 except in rats eating only 12 ppm Zn and receiving the small dose. There were greater differences in bioavailability among foods when tested at the higher Zn status or dose. This may explain inconsistencies seen in comparing Zn bioavailability by traditional growth assay with that seen in 65Zn tracer studies. The authors conclude that Zn status of the experimental animal, as well as the amount of Zn and its source, will affect Zn bioavailability

    The beneficial effects of adiponectin and its negative correlation with BMI are well described. Adiponectin serum levels are altered in eating disorders such as anorexia nervosa, bulimia nervosa or binge eating. Here, we tested the hypothesis that (1) adiponectin serum levels correlate with human eating behavior factors and (2) that genetic variants of the ADIPOQ locus influence both serum levels and eating behavior. We analyzed 11 SNPs within ADIPOQ and in the 5' UTR and measured serum adiponectin levels in 1,036 individuals from the German Sorbs population. The German version of the three-factor eating questionnaire (FEV) was completed by 548 Sorbs. For replication purposes, we included an independent replication cohort from Germany (N = 350). In the Sorbs, we observed positive correlations of restraint with adiponectin serum levels (P = 0.001; r = 0.148) which, however, did not withstand adjustment for covariates (P = 0.083; r = 0.077). In addition, four SNPs were nominally associated with serum adiponectin levels (all P  9.3 × 10(-4)). In our replication cohort, we observed similar effect directions at rs1501229 for disinhibition and hunger. A meta-analysis resulted in nominal statistical significance P = 0.036 (Z score 2.086) and P = 0.017 (Z score 2.366), respectively. Given the observed relationship of the SNPs with adiponectin levels and eating behavior, our data support a potential role of adiponectin in human eating behavior. Whether the relationship with eating behavior is mediated by the effects of circulating adiponectin warrants further investigations. PMID:25542302

    This report, Vol. 2, submitted by the General Electric Co., identifies factors that should be considered in planning interconnected systems and discusses how these factors relate to one another. The objective is to identify all the factors and classify them by their use and importance in arriving at a decision. Chapter 2 discusses the utility system and its system behavior characteristics, emphasizing behavior that affects the planning of the bulk-power generation and transmission system. Chapter 3 introduces interconnection planning by discussing the new system characteristics brought to operation and planning. Forty-two factors associated with cost, reliability, constraints, and coordination are related to each other by factor trees. Factor trees display the relationship of one factor such as reliability to more-detailed factors which in turn are further related to individual characteristics of facilities. These factor trees provide a structure to the presentation. A questionnaire including the 42 factors was completed by 52 system planners from utility companies and government authorities. The results of these questionnaires are tabulated and presented with pertinent discussion of each factor. Chapter 4 deals with generation planning, recognizing the existence of interconnections. Chapter 5 addresses transmission planning, questions related to reliability and cost measures and constraints, and factors related to both analytical techniques and planning procedures. The chapter ends with a discussion of combined generation-transmission planning. (MCW)

    Full Text Available Introducción: Rara vez se ha evaluado la efectividad de las campañas e intervenciones de información pública. Por ello, el estudio de actividades exitosas podría contribuir al desarrollo y puesta en práctica en el futuro de campañas e intervenciones a favor de una alimentación saludable Objetivos: E [...] l objetivo del presente estudio de campañas de información sobre alimentación saludable fue primeramente la identificación de los factores de éxito de las mismas, y seguidamente la descripción de sus inter-relaciones. Métodos: Se entrevistaron a 11 representantes de industrias alimentarias cuyas campañas fueron identificadas como exitosas en una etapa previa del estudio. Las entrevistas fueron luego analizadas con respecto a los factores de éxito potenciales. Estos últimos fueron posteriormente utilizados para desarrollar un modelo de factores de éxito y sus interrelaciones. Resultados: El éxito de los casos estudiados fue atribuido primeramente a las características del ambiente macro, o a una colaboración entre los sectores público y privado. Segundo, se identificó al compromiso de las comunidades, elementos de empoderamiento del grupo objetivo y a la ejecución de medidas de marketing social. Tercero, el éxito puede atribuirse a la adopción por parte de la ciudadanía de las campañas y los cambios estructurales consecuentes. Conclusiones: El modelo y los factores de éxito identificados resaltan que el éxito puede originarse en tres fases cruciales, el diseño y montaje de la campaña, su ejecución y finalmente, su interacción con la ciudadanía. El modelo puede servir como guía para el desarrollo de campañas en el futuro. Abstract in english Introduction: Public campaigns and interventions are rarely fully evaluated regarding their effectiveness. The analysis of past, successful activities can contribute to the future development of public campaigns and interventions for healthier eating. Objectives: The study of public campaigns and in [...] terventions for healthier eating aimed at identifying the underlying success factors and describing their relation. Methods: Interviews were conducted with representatives of 11 cases that had been identified as especially successful in an earlier research step. The interviews were analysed with regard to possible success factors and the latter used to develop a model of success factor interrelation. Results: It was found that success of the cases was first, attributed to characteristics of the macro environment or to public private partnerships in the initiation of campaigns, second, to the engagement of social communities, elements of empowerment of the target group and the implementation of social marketing measures, and thirdly, in citizens adoption of the campaign and in accompanying structural changes. Conclusions: The model and identified success factors underline that success can stem from three crucial phases: the set up of a campaign, the conduction and finally, the interrelation with the citizen. The model can serve as a guide in the future development of campaigns.

    Understanding the triggers of eating in everyday life is crucial for the creation of interventions to promote healthy eating and to prevent overeating. Here, the proximal predictors of eating are explored in a natural setting. Research from laboratory settings suggests that restrained eaters overeat after experiencing anxiety, distraction, and the presence of positive or negative moods, but not hunger; whereas the only factor that triggers eating in unrestrained eaters is hunger. In this stud...

    2015-08-01

    The association between certain foods and masculinity or femininity has been widely discussed in different disciplines. However, extant research has yet to clarify which are the critical dimensions lending these gender connotations to food and thus impacting on the willingness to eat it. We present a study on the role of food type, portion size, and dish presentation as potential factors constituting the gender-based stereotype about food, and their indirect or mediated effect on the intention of men and women to eat certain feminine/masculine stereotyped foods. We manipulated the three features cited above in a 2 (food type: Caprese vs. hamburger)?×?2 (portion size: small vs. big)?×?2 (presentation: elegant vs. rough) full factorial design. Results confirmed a model of moderated mediation: the Caprese salad, the small portion and the elegantly presented dish (in respect to the hamburger, the big portion and the roughly presented dish) tend to be considered "feminine food", and thus women expressed a more pronounced intention to eat it than men. The implications of the findings for both theory and practice are discussed. PMID:25934089

A better understanding of the genetics of these complex traits and the development of more sophisticated molecular biology tools have advanced our understanding of the etiology of EDs. The aim of this review is to critically evaluate the literature on the genetic research conducted on three major EDs: anorexia nervosa, bulimia nervosa, and binge eating disorder. We will first review the diagnostic criteria, clinical features, prevalence, and prognosis of anorexia nervosa, bulimia nervosa, and binge eating disorder, followed by a review of family, twin, and adoption studies. We then review the history of genetic studies of EDs covering linkage analysis, candidate-gene association studies, genome-wide association studies, and the study of rare variants in EDs. Our review also incorporates a translational perspective by covering animal models of ED-related phenotypes. Finally, we review the nascent field of epigenetics of EDs and a look forward to future directions for ED genetic research.

    Full Text Available Eating disorders are considered chronic diseases of civilization. The most studied and well known are anorexia and bulimia nervosa. Anorexia is considered one of the most common psychiatric problems of girls in puberty and adolescence. Due to high mortality and morbidity as well as the increasing expansion of these diseases, it is clear why the amount of research on these diseases is growing worldwide. Eating disorders lead to numerous medical complications, mostly due to late diagnosis. The main characteristic of these diseases is changed behavior in the nutrition, either as an intentional restriction of food, i.e. extreme dieting, or overeating, i.e. binge eating. Extreme dieting, skipping meals, self-induced vomiting, excessive exercise, and misuse of laxatives and diuretics for the purpose of maintaining or reducing body weight are characteristic forms of compensatory behavior of patients with eating disorder. The most appropriate course of treatment is determined by evaluating the patient’s health condition, associated with behavior and eating habits, the experience of one’s own body, character traits of personality, and consequently the development and functioning of the individual. The final treatment plan is individual. Eating disorders are a growing medical problem even in this part of the world. Prevention should be planned in cooperation with different sectors so as to stop the epidemic of these diseases.

    Full Text Available Electronic Data Interchange (EDI implementation is viewed as an important tool for transmission of business data. Yet, its implementation has not reached the predicted level whereby the implementation is often stalled at infancy stage. Many factors were pinpointed as inhibitors or barriers for success of EDI implementation. This study examines key EDI influencing factors and their relationship with implementation level, firm size and type of users. Mail surveys on 108 manufacturers were the main data collection method. Findings indicate that implementation level differs based on influencing factors, while these factors differ based on type of users and do not differ based on firm size. Relatively, internal factors were found to be more significant than external factors. This study also recommends future research to further examine influences of users’ type with different EDI aspects.

    2008-07-01

    During Ramadan month, Muslims should refrain from drinking, eating and smoking from dawn to sunset. Ramadan fasting can be considered as a kind of dietary restriction. Eating restriction is a risk factor for later development of eating disorders. The purpose of this study is to evaluate whether Ramadan fasting changes the eating behaviours of young people, especially girls who are known as the most vulnerable group for eating disorders. Our sample consisted of 79 healthy volunteers from a high school (63 females; mean age = 16.29; 16 males; mean age = 16.31) who fasted during the Ramadan month. No statistically significant differences were found between the scores of EAT (Eating Attitude Test) and BITE (Bulimic Investigatory Test, Edinburgh) which were administered within the weeks before and after Ramadan. According to our results Ramadan fasting restrictions do not seem to change the eating behaviours of young girls and boys. PMID:18444254

    The effectiveness of electron beam (EB) curing of epoxy resins was found to be influenced by catalyst. In the presence of iodonium salt (diaryl iodonium hexafluoroantimonate, C3), the EB curing of epoxy resin is easier than in the presence of triaryl sulfonium hexafluoroantimonate (C1), or triaryl sulfonium hexafluorophosphate (C2), or iron arene containing cationic catalyst (Irgacure 261). The epoxy 616 (diglycidyl ether of bisphenol A) and 648 (diglycidyl ether of phenolic novolacs) can be cured by the above onium salts catalysts C1-C3. The epoxy with glycidyl amino epoxide group (such as AG 80; AFG 90) could not be cured by onium salts catalyst.

    Adolescence is a time of tremendous change in physical appearance. Many adolescents report dissatisfaction with their body shape and size. Forming one's body image is a complex process, influenced by family, peers, and media messages. Increasing evidence shows that the combination of ubiquitous ads for foods and emphasis on female beauty and thinness in both advertising and programming leads to confusion and dissatisfaction for many young people. Sociocultural factors, specifically media exposure, play an important role in the development of disordered body image. Of significant concern, studies have revealed a link between media exposure and the likelihood of having symptoms of disordered eating or a frank eating disorder. Pediatricians and other adults must work to promote media education and make media healthier for young people. More research is needed to identify the most vulnerable children and adolescents.

    In South Africa, more than 2 million people living with HIV are men aged 15 years and older, and heterosexual intercourse remains the predominant mode of HIV transmission. Knowledge of the sociocultural factors that influence men's decisions about whether, when, or how to disclose seropositive status remains incompletely understood. Using the PEN-3 cultural model as a guide, this study explored the sociocultural factors influencing HIV disclosure among men in South Africa. Four focus group discussions with 27 participants were used to determine the perceptions, enabling and nurturing factors that influence how men chose to reveal or conceal knowledge of their seropositive status. The results revealed that notions of male identity in the South African context, family, and community factors contribute to disclosure and nondisclosure of seropositive status among men living with HIV/AIDS. Future interventions should work to address these factors, as they are necessary with supporting disclosure among men living with HIV. PMID:24871161

Analyses covered the data of 47 patients diagnosed with any of the eating disorders according to DSM IV consulted for the first time in the outpatients clinic of the Child and Adolescent Psychiatry Unit between 2002/2004 in Krakow (DGN1, Poland and then followed up between 2009/2011 (DGN2. The influence of the number of variables collected at DGN1 on outcomes was analysed. Results. The outcomes of anorexia nervosa and bulimia nervosa are influenced by some aspects of clinical picture, patients’ objective family situation, their self-image and the perception they have of their family relations. The co-occurrence of depressive symptoms and younger age of parents proved to be the most clinically important negative outcome predictors in the whole group of eating disorders. Discussion. The small size of group in the follow-up study is the most important limitating factor. Conclusion. Outcomes in eating disorders are affected by several psycho-bio-social factors common to all patients and specific for the diagnosis type they initially present.

FONTES DE DADOS: A pesquisa de artigos foi realizada nas bases de dados PubMed e SciELO pela combinação dos termos 'crianças', 'adolescentes', 'comportamento alimentar', 'trans [...] torno alimentar', 'bulimia' e 'anorexia', nos idiomas português e inglês. Foram considerados os artigos publicados entre 2007 e 2011, sendo selecionados 49 que analisaram o desenvolvimento do comportamento alimentar e de seus transtornos, a anorexia e a bulimia nervosa e os transtornos alimentares não especificados. SÍNTESE DOS DADOS: Os transtornos alimentares, em especial os não especificados, mostraram-se comuns na infância e na adolescência. Sua presença foi atribuída principalmente ao ambiente familiar e à exposição aos meios de comunicação. As comorbidades psicológicas muitas vezes acompanhavam o diagnóstico do transtorno. CONCLUSÕES: Dentre os fatores de risco para os transtornos alimentares, destacaram-se a mídia e os ambientes social e familiar. A influência da mídia e do ambiente social foi associada, principalmente, ao culto à magreza. Já no âmbito familiar, o momento das refeições mostrou-se fundamental na determinação do comportamento alimentar e no desenvolvimento de seus transtornos. Os transtornos alimentares se associaram a problemas nutricionais (déficit no crescimento e ganho de peso), à saúde bucal (queilose, erosão dental, periodontites e hipertrofia das glândulas salivares) e aos prejuízos sociais.

    Researchers in this study explored the reactions of women with breast cancer and identified factors influencing treatment decisions. A qualitative exploratory approach was employed. Participants were recruited from a tertiary hospital and a breast cancer support group. Purposive sampling recruited 12 women. It was found that women identified breast lesions accidentally or intentionally and that diagnosis was delayed. Emotional reactions to diagnosis included shock and sadness. Factors that influenced treatment were the influence of other people, alternative sources of treatment, faith and support, knowledge, "tuning the mind," and effects on intimacy. Health professionals should develop effective communication and counseling skills for clients. PMID:24750095

    Full Text Available Decision-making is one of the most important functions of managers in any kind of organization. Among different manager's decisions strategic decision-making is a complex process that must be understood completely before it can be practiced effectively. Those responsible for strategic decision-making face a task of extreme complexity and ambiguity. For these reasons, over the past decades, numerous studies have been conducted to the construction of models to aid managers and executives in making better decisions concerning the complex and highly uncertain business environment. In spite of much work that has been conducted in the area of strategic decision-making especially during the 1990's, we still know little about strategic decision-making process and factors affecting it.This paper builds on previous theoretical and empirical studies to determine the extent to which contextual factors impact the strategic decision-making processes. Results showed that researches on contextual factors effecting strategic decision-making process are either limited or have produced contradictory results, especially studies relating decision’s familiarity, magnitude of impact, organizational size, firm’s performance, dynamism, hostility, heterogeneity, industry, cognitive diversity, cognitive conflict, and manager’s need for achievement to strategic decision-making processes. Thus, the study of strategic decision-making process remains very important and much more empirical research is required before any definitive conclusion can be reached.

    The development of eating disorders including anorexia nervosa, bulimia nervosa, binge eating disorder, and atypical eating disorders that affect many young women and even men in the productive period of their lives is complex and varied. While numbers of presumed risk factors contributing to the development of eating disorders are increasing, previous evidence for biological, psychological, developmental, and sociocultural effects on the development of eating disorders have not been conclusive. Despite the fact that a huge body of research has carefully examined the possible risk factors associated with the eating disorders, they have failed not only to uncover the exact etiology of eating disorders, but also to understand the interaction between different causes of eating disorders. This failure may be due complexities of eating disorders, limitations of the studies or combination of two factors. In this review, some risk factors including biological, psychological, developmental, and sociocultural are discussed. PMID:25206042

    Full Text Available The continuous supply of energy resources is essential for the development of any nation. The economic and social life of any nation depends enormously on the energy resources. Over the past few years the energy crisis is becoming a major issue in developing countries as Pakistan. Oil, Natural gas and hydro are the three major energy resources of the Pakistan. These conventional energy resources were being exploited in the past leading to an issue of energy crisis in the country. Replacing expensive imported energy resources with coal briquettes made from indigenous coal reserves can provide fuel for the local residential and commercial markets. Coal briquettes formation is a process to convert coal powder into a specific shape with the help of a binder. An external force is applied to the coal binder mixture to make a firm body of desired shape. The briquettes formed this way will not disintegrate under normal conditions of transportation and use. Coal briquettes are preferred over raw coal because they are a smokeless, strong and low emissive fuel that can be used in numerous domestic and commercial applications. The performance of coal briquettes formed is dependent largely upon its thermal properties and the mechanical strength. Nowadays an environmentally safe briquettes formation process is also included in the performance criteria of coal briquettes. The mechanical strength of coal briquettes affects its storage and transportation to the intended market. The studies on coal briquettes show that coal briquettes quality depends on many factors like the type of binder, quantity of binder, grade of coal, moisture level, coal particle size and its distribution etc. These factors along with some of the factors as time of compaction, compaction temperature, and compaction pressure and moisture level are discussed in this paper to evaluate the performance of briquetting technology in future.

    The purpose of this study was to examine factors that impact consumer satisfaction with health care. This is a secondary analysis of the Center for Studying Health System Change's 2010 Health Tracking Household Survey. Regression analysis was used to examine the impact of treatment issues, financial issues, family-related issues, sources of health care information, location, and demographics-related factors on satisfaction with health care. The study involved 12280 subjects, 56% of whom were very satisfied with their health care, whereas 66% were very satisfied with their primary care physician. Fourteen percent of the subjects had no health insurance; 34% of the subjects got their health care information from the Web. Satisfaction with primary care physician, general health status, promptness of visit to doctor, insurance type, medical cost per family, annual income, persons in family, health care information from friends, and age significantly impacted satisfaction with health care. The regression models accounted for 23% of the variance in health care satisfaction. Satisfaction with primary care physicians, health insurance, and general health status are the 3 most significant indicators of an individual's satisfaction with health care. PMID:25068881

  8. Factors influencing EPR dosimetry in fingernails

    International Nuclear Information System (INIS)

    The technique based on the detection of ionizing radiation induced radicals by EPR in tooth enamel is an established method for the dosimetry of exposed persons in radiological emergencies. Dosimetry based on EPR spectral analysis of fingernail clippings, currently under development, has the practical advantage of the easier sample collection. A limiting factor is that overlapping the radiation induced signal (RIS), fingernails have shown the presence of two mechanically induced signals, called MIS1 and MIS2, due to elastic and plastic deformation respectively, at the time of fingernails cutting. With a water treatment, MIS1 is eliminated while MIS2 is considerably reduced. The calibration curves needed for radiation accident dosimetry should have 'universal' characteristics, ie. Represent the variability that can be found in different individuals. Early studies were directed to the analysis of factors affecting the development of such universal calibration curves. The peak to peak amplitude of the signal before and after the water treatment as well as the effect of size and number of clippings were studied. Furthermore, the interpersonal and intrapersonal variability were analyzed. Taking into account these previous studies, the optimal conditions for measurement were determined and EPR spectra of samples irradiated at different doses were used for the developing of dose-response curves. This paper presents the analysis of the results.(authors)

    Full Text Available There are various influences and obstacles when planning an educational curriculum. However, it is imperative that we overcome these barriers and arm our future doctors with the knowledge and skills to serve the needs of the 21st Century patient. As we will discuss, the imprint of globalisation on the landscape of Irish medicine highlights the importance of delivering a diverse curriculum with international dimensions so that knowledge and skills can transfer across borders. We will also explore how medical emigration has a negative impact on the delivery of services in Ireland and in maintaining a sustainable workforce. In addition, financial constraints will always play a role in the logistics of Medical education and it is important that we try to get the best value for money by adding more cost effective virtual learning modules to the traditional classroom based approach. Further research is needed into career satisfaction within Medicine. If we can begin to understand what motivates doctors to stay within the Irish Medical system, then we can design a curriculum with retention of graduates in mind. We believe that if we foster a culture of education, guidance and support in our universities and hospitals, we will ensure that a strong, competent and resilient breed of doctors emerge to serves future generation.

    2012-11-01

    Currently, the outcome and indications of unicompartmental knee arthroplasty (UKA) are still controversial. We retrospectively reviewed a consecutive case series of UKA done by a single surgeon between 2004 and 2007 including 178 knees (140 patients). There were 31 lateral UKA and 147 medial UKA. With a minimum follow-up of 24 months (average 54 months) in 159 knees (other 19 knees were lost to follow-up at 3 to 18 months after surgery), 6 knees (3.8%, all medial UKA) were converted to total knee arthroplasty in 17 to 66 months (average 33 months). We found that the outcome of UKA was not influenced by the patient's age, body mass index, or early degeneration in the patellofemoral joint (PFJ). Compared with other reports, there was a greater proportion of lateral UKA in our series (17.4%). Although lateral UKA showed a trend toward less complications and implant failure compared with medial UKA, WOMAC scores (Western Ontario and McMaster Universities Osteoarthritis Index) were similar between the two types of partial knee arthroplasty. Our results indicate that young age, obesity, and early degeneration in the PFJ may not be contraindications to UKA, and lateral UKA functions as well as, if not better than medial UKA. However, a long-term follow-up is required to confirm these findings. PMID:23150345

    2014-06-01

    This study constructed a mathematic model of a variable frequency centrifugal chiller using Simulink software. By running the simulation, it was discovered that when the other factors are constant, the EER (Energy Efficiency Ratio) of the chiller increases with decreases in the temperature of the cooling water and increases in the temperature of the chilled water. The effect of changes in the cooling water temperature on the EER of the chiller is stronger than that of changes in the chilled water temperature. In addition, as the chiller load decreases, the EER increases until reaching a maximum, after which it decreases. Furthermore, the EER of chillers working under a constant flow rate is slightly higher than that of those working under varying flow rates.

  15. Factors influencing ?-crystallin association with phospholipid vesicles

    Cobb, Brian A.; Petrash, J. Mark

    2010-01-01

    Purpose Lens lipids undergo a number of changes with age, including an overall increase in phospholipid acyl chain saturation and a decrease in length. In addition, the amount of membrane bound ?-crystallin increases dramatically with age and with the onset of cataract. The aim of this study was to determine if a link exists between age and cataract associated changes in lens lipids and the changes in ?-crystallin membrane association. Methods Protein-free lipid vesicles composed of a wide variety of synthetic and lens-derived lipid vesicles were formed by sonication. These vesicles were used with fluorescent native and recombinant ?-crystallin conjugates in vesicle binding assays. Vesicles were collected by centrifugation and bound ?-crystallin was quantified with fluorescence intensity measurements. Results ?-Crystallin complexes showed remarkably similar binding profiles for all lipid vesicles tested, regardless of lipid origin, phospholipid head group, acyl chain length or saturation, and inclusion of cholesterol. In addition, recombinant ?-crystallin complexes bind to these vesicles in a manner that is essentially indistinguishable from that of native human and bovine ?-crystallins. Unlike ?-crystallin binding to lens membranes containing intrinsic proteins, binding of ?-crystallin to protein-free vesicles was very high capacity and unsaturable. Conclusions We conclude from these data that the binding of ?-crystallin to lens membranes is not lipid-specific. Furthermore, protein post-translational changes, such as phosphorylation, do not appear to alter ?-crystallin binding to these vesicles. Given the linearity of the binding curves, we propose that the only limiting factor for normal ?-crystallin membrane binding is available surface area on the bilayer. Finally, the present data suggests that increased in vivo membrane association of ?-crystallin is not a result of lipid changes, but more likely a result of non-lipid factors such as the accumulation of high molecular weight forms of ?-crystallin.

    Full Text Available Studying the causes of hospitalization prolongation terms in COPD exacerbation may help optimize treatment, reduce expenditures on the patient and avoid episodes relapses. The aim of the work was to determine the factors affecting the length of hospitalization due to COPD exacerbation. A retrospective analysis of medical records of inpatients hospitalized with COPD exacerbation to therapeutic department of CI "Dnipropetrovsk municipal clinical hospital N 6" of “Dnipropetrovsk regional council" during three years was done. It was found that age, height, number of comorbidities, presence of any symptoms or changes in laboratory analyses do not affect the duration of hospitalizations due to COPD exacerbations. Regardless of the frequency of hospital admissions, length of hospitalization moderately positively and reliably correlates with the disease stage (R = 0,516, p <0,001. Decrease of respiratory function indices, especially FEV1, significantly increases the length of stay in the hospital both in case of one (R = -0,457, p <0.001 or multiple hospitalization during three years (R = -0,512, p <0.001. Reduced body weight and low body mass index during hospitalization are prognostically unfavorable factors, because these parameters, though weakly, but reliably negatively correlate with the number of days spent in the hospital (R = -0,195, p = 0,028 and R = -0,246, respectively, p = 0,005. In the population of patients hospitalized due to COPD exacerbation, moderately positive reliable correlation (R = 0,392, p <0,001 between the length of hospital stay and number of hospitalizations during three years was established. The dependence of hospitalization duration in COPD exacerbations on patient’s gender requires further investigation.

    2009-12-01

    Full Text Available Electronic commerce research has shown that a very wide variety of factors such as website quality and vendor reputation influence consumer behaviors and outcomes. These behaviors and outcomes include: trust, intention to transact, and return visits. However, these factors are typically studied in i [...] solation and often show conflicting results. This paper proposes a unifying model of online identity (or e-image) that combines the various factors that influence user perceptions of an e-business. Survey results support the importance of a wide variety of e-image factors when forming impressions online and show that while information content is the foremost concern for most users, the importance of other factors varies depending on the role of the user in establishing a relationship with the owner of the online identity.

    Full Text Available This study examined correlates of degree attainment in high school dropouts. Participants were high school dropouts of Mexican American or non-Latino white descent who had no degree, a high school degree, or a GED certificate. This study was unique in that it accounted for sample bias of missing data through the use of multiple imputation, it considered students who had dropped out as early as 7th grade, and it was able to include variables found significant in previous research on returning dropouts. Logistic regression analyses identified a parsimonious set of factors which distinguished dropouts who held degrees (diploma or GED from those who did not. Similar analyses were performed to distinguish participants who had attained diplomas from those who had attained GEDs. It was estimated that 59.2% of dropouts return to obtain high school credentials. School capability, age at dropout, and socio-economic status significantly predicted degree attainment. Presence of children, higher school capability and socio-economic status were associated with GED attainment, while later grade at dropout was associated with diploma attainment. These relationships did not vary by ethnicity, although degree attainment was less likely for Mexican American dropouts. The study concludes that dropping out is not the end of a student's education, and more research should be directed toward returning dropouts. Further, the focus of such research should be expanded to include a more positive and broader range of correlates.

  4. Communicating healthy eating to adolescents

    DEFF Research Database (Denmark)

    Chan, Kara; Prendergast, Gerard

    2009-01-01

    Purpose - This study explores perceptions of healthy/unhealthy eating, and perceptions of various socializing agents encouraging healthy eating, amongst Chinese adolescents. Design/methodology/approach - A survey was conducted of 152 seven, eighth and ninth grade Hong Kong students. A structured questionnaire with closed-ended questions was distributed in three public secondary schools. Findings - Results showed that respondents frequently ate out with friends and frequently consumed a range of relatively unhealthy food (candies, chips, and soft drinks). They perceived that a balanced diet and eating at a regular time were the most important attributes of healthy eating. In terms of situational influences on their consumption, respondents most likely ate unhealthy food at parties, when eating out or with friends. They most likely ate healthy food at home and when they were sick. Looking at socializing agents, respondents claimed that parents and government publicity asked them to eat healthy food more often than teachers or friends. Parents were also perceived as being the most effective source in encouraging them to eat healthy food. In terms of alternative advertising appeals discouraging unhealthy eating, respondents considered news and fear appeals the most effective, while popularity and achievement appeals were considered relatively less effective. Research limitations/implications - The respondents were chosen from three secondary schools (two co-ed schools and one school for boys). These three schools may not be representative of all schools in Hong Kong or elsewhere, thus limiting the generalizabilty of the findings. Practical implications - The study can serve as a guideline for social services marketing professionals targeting adolescents. Looking at the findings in relation to socializing agents, social services marketers can consider influencing the adolescents eating habits through the parents. As government publicity was perceived as a relatively weak socializing agent, there is a need to review health education materials targeting adolescents. Looking at the findings in relation to different advertising appeals discouraging unhealthy eating, news and fear appeals should be considered, as these were considered relatively more likable and effective than other types of appeals. Originality/value - This paper offers insights into designing communication strategies for adolescents. It is original in that it focuses on adolescents, and explores the perceptions of various socializing agents influencing healthy eating.

    Full Text Available The main objective of this paper is to present the factors with influence on the sustainable university management and the relationships between them. In the scientific approach we begin from a graphical model, according to which the extracurricular activities together with internal environmental factors influence students’ involvement in such activities, the university attractiveness, their academic performance and their integration into the socially-economic and natural environment (components related with sustainable development. The model emphasizes that individual performances, related to students’ participation in extracurricular activities, have a positive influence on the sustainability of university management. The results of the study have shown that the university sustainability may be influenced by a number of factors, such as students’ performance, students’ involvement in extracurricular activities or university’s attractiveness and can in turn influence implicitly also the sustainability of university management. The originality of the paper consists in the relationships study using the modeling method in general and informatics tools of modeling in particular, as well as through graphical visualization of some influences, on the sustainability university management.

    2006-01-01

    AIMS: The aim of this study was to assess the relative influence of school class on health behaviour among adolescents versus that of the family's socioeconomic status and individual factors among adolescents. METHODS: The material comprised 3,458 students in grades 8 and 9 in 244 school classes. Data were collected through questionnaires completed by the students and by their class teacher and information from the school physician. Multilevel analysis was used to indicate the relative significance of individual and school class characteristics. RESULTS: We find no consistent pattern between the mother's socioeconomic status and the included health behaviour measurements; however, adolescents from the lower socioeconomic groups had a higher risk of unhealthy dietary habits and adolescents whose mothers were unemployed had a significantly lower risk of drinking alcohol weekly versus all other adolescents. Not living with both biological parents, focusing on friends, and not being very academically proficient were associated with an increased risk of harmful health behaviour. Health behaviour varied substantially between school classes, especially for daily smoking, weekly alcohol consumption, and use of hashish and other euphoriants. Circumstances in the school class more profoundly influenced risk behaviour among adolescents (smoking, alcohol consumption, and use of hashish or other euphoriants) than their dietary habits (eating breakfast, frequent intake of fruit and vegetables, and frequent intake of soft drinks). CONCLUSIONS: The school class had the relatively strongest influence on adolescents' risk behaviour (smoking, alcohol intake, and use of hashish or other euphoriants), whereas family circumstances comprised the strongest influence on dietary habits.

Many of these factors are from the environment where traditional view commonly divided into internal and external factors. This paper presents the findings of a study to evaluate the influencing factors and impact on organizational structure of a sample of firms located in Hanoi, Vietnam. Structured questionnaires were administered with respect to these factors. The variables studied were identified from among the factors considered in contingency theory and by incorporating elements of the strategic choice approach. After grouping the variables into two factors (related to external and internal respectively, the results revealed three groups of firms according to how they regarded the impact of these factors on organizational structures. In those groups that consider the variables of internal factors to be modifiers of structure the organizational structures are of the “complex classical” type, whereas simple forms predominate in the group that believes these variables do not modify their structure.

    To assess the efficacy of percutaneous transluminal angioplasty (PTA) in patients with infrapopliteal arterial disease, and to determine the influencing factor for prognosis. A total of 55 patients (60 limbs) with infrapopliteal arterial stenosis or occlusion underwent PTA. Atherosclerotic risk factors, clinical symptoms, TransAtlantic Inter-Society Consensus (TASC) classification, and vascular wall calcification were evaluated before PTA. The number of patent infrapopliteal arteries was estimated, and the outcome was evaluated by symptom relief and limb salvage. Technical success was achieved in 53/60 limbs (88.3%) and 81/93 arteries (87.1%), TASC classification (p = 0.038) and vascular calcification (p = 0.002) influenced on technical failure. During follow-up, 26 of 55 limbs (47%) achieved symptom relief and 42/55 limbs (76%) underwent limb salvage. Non-diabetic patients (9/12, 75%) were superior to diabetic patients (17/43, 40%) in terms of symptom relief (p = 0.024). TASC classification and vascular wall calcification influenced on symptom relief and limb salvage. The number of patent infrapopliteal arteries after PTA influenced symptom relief (p < 0.001) and limb amputation (p = 0.003). PTA in patients with chronic critical limb ischemia is worthwhile as a primary treatment. The influence factors should be considered before PTA, and PTA should be performed in as many involved arteries as possible.

    Our objective was to investigate the Salmonella and Campylobacter contamination of traditional ready-to-eat street-vended poultry dishes and to assess the association of some restaurant characteristics and cooking practices with the contamination of these meals. One hundred and forty-eight street-restaurants were studied from January 2003 to April 2004 in Dakar. A questionnaire was submitted to the managers, and samples of ready-to-eat poultry dishes were taken. Salmonella spp. was isolated in 20.1% of the 148 street-restaurants studied and in 10.1% samples of poultry dishes. The most prevalent serovars isolated were Salmonella hadar, Salmonella enteritidis and Salmonella brancaster. Campylobacter jejuni was detected in only 3 restaurants and 3 poultry dishes. Not peeling and not cleaning vegetables and other ingredients during meal preparation (OR=3.58), dirty clothing for restaurant employees (OR=4.65), reheating previously cooked foods (OR=5.2), and no kitchen and utensils disinfection (OR=3.47) were associated with an increasing risk of Salmonella contamination. Adequate cooking procedures decreased the risk of Salmonella contamination (OR=0.15). PMID:16083818

    2014-12-01

    A significant proportion of worker fatalities within Australia result from truck-related incidents. Truck drivers face a number of health and safety concerns. Safety culture, viewed here as the beliefs, attitudes and values shared by an organisation's workers, which interact with their surrounding context to influence behaviour, may provide a valuable lens for exploring safety-related behaviours in heavy vehicle operations. To date no major research has examined safety culture within heavy vehicle industries. As safety culture provides a means to interpret experiences and generate behaviour, safety culture research should be conducted with an awareness of the context surrounding safety. The current research sought to examine previous health and safety research regarding heavy vehicle operations to profile contextual factors which influence health and safety. A review of 104 peer-reviewed papers was conducted. Findings of these papers were then thematically analysed. A number of behaviours and scenarios linked with crashes and non-crash injuries were identified, along with a selection of health outcomes. Contextual factors which were found to influence these outcomes were explored. These factors were found to originate from government departments, transport organisations, customers and the road and work environment. The identified factors may provide points of interaction, whereby culture may influence health and safety outcomes. PMID:25269101

    2015-07-01

    Research on eating behaviour has identified several potentially relevant eating-related traits captured by different questionnaires. Often, these questionnaires predict Body Mass Index (BMI), but the relationship between them has not been explicitly studied. We studied the unity and diversity of questionnaires capturing five common eating-related traits: Power of Food, Eating Impulsivity, emotional eating, Disinhibition, and binge eating in women from Estonia (n?=?740) and Canada (n?=?456). Using bifactor analysis, we showed that a) these questionnaires are largely explained by a single factor, and b) relative to this shared factor, only some questionnaires offered additional variance in predicting BMI. Hence, these questionnaires seemed to characterise a common factor, which we label Uncontrolled Eating. Item Response Theory techniques were then applied to demonstrate that c) within this common factor, the questionnaires could be placed on a continuum of Uncontrolled Eating. That is, Eating Impulsivity focused on the milder degree, Power of Food Scale, emotional eating scales, and Disinhibition on intermediate degrees, and the Binge Eating Scale on the most severe degrees of Uncontrolled Eating. In sum, evidence from two samples showed that questionnaires capturing five common BMI-related traits largely reflected the same underlying latent trait - Uncontrolled Eating. In Estonia, some questionnaires focused on different severities of this common construct, supporting a continuum model of Uncontrolled Eating. These findings provide a starting point for developing better questionnaires of the neurobehavioural correlates of obesity, and provide a unifying perspective from which to view the existing literature. R scripts and data used for the analysis are provided. PMID:25769975

    Intuitive eating is an adaptive dietary behavior that emphasizes eating in response to physiological hunger and satiety cues. The Intuitive Eating Scale-2 (IES-2) measures such attitudes and behaviors. The aim of the present study was to adapt the IES-2 to the French context and to test its psychometric properties in 335 women and 297 men participating in the NutriNet-Santé study. We evaluated the construct validity of the IES-2 by testing hypotheses with regard to its factor structure, relationships with scores of the revised 21-item Three Factor Eating Questionnaire and the Center for Epidemiologic Studies Depression scale, and differences between "a priori" relevant subgroups. First, the exploratory factor analysis revealed three main dimensions: Eating for Physical Rather than Emotional Reasons, Reliance on Hunger and Satiety Cues, and Unconditional Permission to Eat. Second-order confirmatory factor analysis upheld the 3-factor solution influenced by a broader intuitive eating dimension. IES-2 total score was negatively related to cognitive restraint (r?=?-0.31, P?Physical Reasons, and Unconditional Permission to Eat subscales. Current or former dieters had lower scores on the IES-2 total scale and on all subscales than did those who had never dieted (all P?eating behaviors in empirical and epidemiological studies in the general population.

    There is little documentation about how the union of self-help and professional treatment services influences client treatment satisfaction. This study examines the relationship of treatment characteristics indicative of program size, staffing patterns, Alcoholics Anonymous (AA) influence, and staff recovery status to client satisfaction. Thirty-six public substance abuse treatment programs participated in this study. At outpatient programs, satisfaction was related to program size, and the number of paraprofessional and medical staff; satisfaction was unrelated to AA influence on treatment. For residential clients, AA influence on treatment and AA beliefs held by staff were consistently related to satisfaction; factors related to program size and staffing patterns were independent of satisfaction. The results question the appropriateness of self-help interventions in all settings, and emphasize contextual differences in outpatient and residential programs. PMID:7703712

    Dietary restraint is a prospective risk factor for the development of binge eating and bulimia nervosa. Although many women engage in dietary restraint, relatively few develop binge eating. Dietary restraint may only increase susceptibility for binge eating in individuals who are at genetic risk. Specifically, dietary restraint may be a behavioral “exposure” factor that activates genetic predispositions for binge eating. We investigated this possibility in 1,678 young adolescent and adult...

  14. Consumer's Online Shopping Influence Factors and Decision-Making Model

    Science.gov (United States)

    Yan, Xiangbin; Dai, Shiliang

    Previous research on online consumer behavior has mostly been confined to the perceived risk which is used to explain those barriers for purchasing online. However, perceived benefit is another important factor which influences consumers’ decision when shopping online. As a result, an integrated consumer online shopping decision-making model is developed which contains three elements—Consumer, Product, and Web Site. This model proposed relative factors which influence the consumers’ intention during the online shopping progress, and divided them into two different dimensions—mentally level and material level. We tested those factors with surveys, from both online volunteers and offline paper surveys with more than 200 samples. With the help of SEM, the experimental results show that the proposed model and method can be used to analyze consumer’s online shopping decision-making process effectively.

    Full Text Available Eating disorders have received growing attention by professionals aswell as mass media (Shorter, Quinton et al. 2007. The most recent ISTAT data (Italian Institute for Statistics reveal that about 3 million people (5% of the Italian population suffer from these disorders, 90-95% females with two peaks of onset at 14 and at 18. Especially at this age, socio-cultural factors are crucialto the development of ideals (Tylche, Subich 2002, cognitions and expectations concerning body image (Schilder, 2002, nutrition and weight (Halmi, 2003.These factors can be divided into four main categories: ‘the cultural pressure to acquire a thin body; the change in the woman’s social role; the mythical character granted to eating disorders; the prejudice against obesity’ (Dalle Grave, 2007. So far, the literature on this subject, however wide, has provided no conclusive data with reference to related issues, such as psychiatric comorbidities(Blinder et al, 2007. In particular, this study focused on the aspectof control, a significant feature of the Obsessive-Compulsive Disorder too, (Couturier, 2004 and on body-image disperception, peculiar to eating disorders (Neumark-Sztainer, 2000. To investigate co-morbidity between eating disorders and Obsessive-Compulsive Disorder, a questionnaire including items of the Body Shape Questionnaire and the Yale-Brown Obsessive Compulsive Scale (Dalle Grave, Ghisi, Calugi, 2006 was administered to a sample of adolescent students. The results provide significant correlations between Calculation Compulsions and the BSQ Behaviours variable, between Current MiscellaneousCompulsions and Body Image, between Current Miscellaneous Compulsionsand Body Shape/Self Esteem. Therefore the study provides further evidence in support of co-morbidity.

    Full Text Available Abstract Background Unnecessary ambulance use has become a socioeconomic problem in Japan. We investigated the possible relations between socioeconomic factors and medically unnecessary ambulance calls, and we estimated the incremental demand for unnecessary ambulance use produced by socioeconomic factors. Methods We conducted a self-administered questionnaire-based survey targeting residents of Yokohama, Japan. The questionnaire included questions pertaining to socioeconomic characteristics, dichotomous choice method questions pertaining to ambulance calls in hypothetical nonemergency situations, and questions on the city's emergency medical system. The probit model was used to analyze the data. Results A total of 2,029 out of 3,363 targeted recipients completed the questionnaire (response rate, 60.3%. Probit regression analyses showed that several demographic and socioeconomic factors influence the decision to call an ambulance. Male respondents were more apt than female respondents to state that they would call an ambulance in nonemergency situations (p Conclusion Results of the study suggest that several socioeconomic factors, i.e., age, gender, household income, and possession of a car, influence a person's decision to call an ambulance in nonemergency situations. Hesitation to use an ambulance and knowledge of the city's primary emergency medical center are likely to be important factors limiting ambulance overuse. It was estimated that unnecessary ambulance use is increased approximately 10% to 20% by socioeconomic factors.

  18. Factors influencing societal response of nanotechnology: an expert stakeholder analysis

    International Nuclear Information System (INIS)

    Nanotechnology can be described as an emerging technology and, as has been the case with other emerging technologies such as genetic modification, different socio-psychological factors will potentially influence societal responses to its development and application. These factors will play an important role in how nanotechnology is developed and commercialised. This article aims to identify expert opinion on factors influencing societal response to applications of nanotechnology. Structured interviews with experts on nanotechnology from North West Europe were conducted using repertory grid methodology in conjunction with generalized Procrustes analysis to examine the psychological constructs underlying societal uptake of 15 key applications of nanotechnology drawn from different areas (e.g. medicine, agriculture and environment, chemical, food, military, sports, and cosmetics). Based on expert judgement, the main factors influencing societal response to different applications of nanotechnology will be the extent to which applications are perceived to be beneficial, useful, and necessary, and how 'real' and physically close to the end-user these applications are perceived to be by the public.

    Full Text Available The purpose of this paper is to analyze the existing theories for the capital structure of a corporation and to determine the factors that influence the financing decisions of Romanian corporations. The gearing ratios vary a lot among Romanian corporations pointing out the fact that the internal specific factors are the ones with a greater impact upon their capital structure, and not the external factors. Our empiric research evaluates the determining factors for the debt ratio (total debt/total assets of some Romanian corporations, focusing on its explanatory variables by including them within simple and multiple econometric models. The panel data indicators computed for the companies in the Cluj area listed on the Bucharest Stock Exchange were evaluated with the OLS and FEM techniques.The results have been interpreted, pointing out that company size and asset turnover seem to have a positive influence upon the debt ratio of selected companies, while profitability and liquidity seem to influence the debt ratio of selected companies negatively.

  1. Eating Difficulties, Nutrition, Meal Preferences and Experiences Among Elderly A Literature Overview From a Scandinavian Context

    Directory of Open Access Journals (Sweden)

    2014-10-01

    Full Text Available The risk of malnutrition increases with ageing, resulting in poorer health and higher risk of disease. Eating difficulties are important risk factors for malnutrition. Moreover, independence in relation to food and meals is highly rated by the elderly and has been associated with health and well-being. The purpose of this literature overview was to provide insights into nutritional status, food choice and preferences as well as the meal situations of home-living elderly (65+ people with motoric eating difficulties focusing on Scandinavia. The overall aim is to support independence and to prevent malnutrition. Nutritional status in the elderly was found to be negatively influenced by motoric eating difficulties including problems with manipulating food on the plate and transporting food to the mouth. Motoric eating difficulties may result in practical simplifications such as use of pre-prepared meals, less advanced cooking, and omission of certain meal constituents in order to avoid e.g. mismanagement and spillage. Eating difficulties are often accompanied by feelings of guilt and shame. Choosing smaller portions, reducing the number of eating episodes and not cooking independently have been associated with a higher risk of malnutrition. The nutritional effects of eating difficulties may be exacerbated by diminished chemosensory functions. Furthermore, both past and present food preferences should be considered in order to meet nutritional needs and meal satisfaction. Development of refined and socially accepted eating aids, in combination with tasty and nutritious products, is important in order to promote healthy and independent living among home-living elderly with motoric eating difficulties.

    2015-03-01

    This study explores whether the coping style of teenage girls with and without an eating disorder is similar to that of their mothers' (biological and adoptive), and whether teens with disordered eating utilize more maladaptive coping compared with those without. Eating disorder was diagnosed using the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision criteria, and the Coping Inventory for Stressful Situations was administered to distinguish the coping style of the participants. Our findings suggest that daughters coped very similarly to their mothers in either group. Contrary to previous studies, our sample of teenage girls with eating disorders as well as their mothers utilized less frequently the avoidance-distraction coping compared with the girls without eating disorders and their mothers. These findings reinforce the importance for family involvement and for simultaneous focus on intrapersonal and interpersonal maintenance factors during eating disorder treatment. PMID:25645347

    Optimizing control systems supplement conventional Distributed Control Systems and Programmable Logic Controllers. They continuously implement set points, which aim at maximizing the profitability of plant operation. They are becoming an integral part of modern mineral processing plants. This trend is justified by economic considerations, optimizing control being among the most cost-effective methods of improving metallurgical plant performance. The paper successively analyzes three sets of factors, which influence the profitability of optimizing control systems, and provides guidelines for analyzing the potential value of an optimizing control system at a given operation: external factors, such as economic factors and factors related to plant feed; features of the optimizing control system; and subsequent maintenance of the optimizing control system. It is shown that pay back times for optimization control projects are typically measured in days. The OCS software used by the authors for their applications is described briefly. (author)

    2009-01-01

    Full Text Available The frequency of eating disorders has been increased over the course of last 50 years. Its history reveals that different forms of eating disorders have actually been existed for a long period of time but the most recognized eating disorders like Anorexia Nervosa and Bulimia Nervosa have only recently been included to the official classification systems. It is being argued that biological genetic load and hypothalamic neuromediator factors are the main causes for the etiology of eating disorders, which may cause appearance of several physical symptoms, have a poor prognosis, have a high risk of recurrence, and have a high rate of fatality among psychiatric disorders. Among psychological factors, the emphasis is on family structure and the patient-family relations, and it’s being claimed that the form of the relation that the patient has with his/her parents is effective on eating disorders. It’s expressed that the families of patients with eating disorders are less emphatic, less supportive and have higher expectations. Furthermore, findings reveal that more cases of familial problems and fights, depression, anxiety, alcoholism and any kind of eating disorder are being encountered within the families of patients with eating disorders. In this study the literature on the relationship between eating disorder and family structure has been reviewed.

    Multiple factors influence voice quality measurements (VQM) obtained during an acoustic voice assessment including: gender, intrasubject variability, microphone, environmental noise (type and level), data acquisition (DA) system, and analysis software. This study used regression trees to investigate the order and relative importance of these factors on VQM including interaction effects of the factors and how the outcome differs when the acoustic environment is controlled for noise. Twenty normophonic participants provided 20 voice samples each, which were recorded synchronously on five DA systems combined with six different microphones. The samples were mixed with five noise types at eight signal-to-noise ratio (SNR) levels. The resulting 80,000 audio samples were analyzed for fundamental frequency (F(0)), jitter and shimmer using three software analysis systems: MDVP, PRAAT, and TF32 (CSpeech). Fifteen regression trees and their Variable Importance Measures were utilized to analyze the data. The analyses confirmed that all of the factors listed above were influential. The results suggest that gender, intrasubject variability, and microphone were significant influences on F(0). Software systems and gender were highly influential on measurements of jitter and shimmer. Environmental noise was shown to be the prominent factor that affects VQM when SNR levels are below 30 dB.

    Full Text Available The sustained economic growth in Romania during the period 2000-2008 was not accompanied by a regional convergence of the living standards. Specific factors, such as the persistence of regional specialization of employment and the dominance of subsistence households in rural areas still shape the regional disparities in economic performance. The economic crisis determined a decrease in the average household income, while the impact was unequally distributed by regions. The paper aims at measuring the cross-regional variation of the household income at NUTS2 level. In order to identify the specific factors which have mostly influenced the income changes, panel estimation is used.

    Full Text Available The paper combines the social capital theory, the ordered choice model, and the case study in order to analyze the influence factors of the rural human consumption. The results show the presence of inverted U shape curve relation between human consumption amount and age. Human communication range, income, the highest single human consumption amount and the minimum amount, occupation, family population, the existing of human consumption capacity and the scope of the existing relationships between interpersonal relationship satisfaction and other factors on human consumption level has positive influence on human consumption level. Domestic researches on human behaviour are wide, but most of the studies are focused on the social, human, and psychological disciplines. For the origin of human consumption, scholars focus on four aspects like novelty, human or mutual needs. This research is based on field investigation conducted in Niuxintai village, Liaoning Province, in order to understand the current situation of the rural human consumption in China, and to explain the function and influencing factors of human consumption.

  12. Adolescents' perceptions of healthy eating and communication about healthy eating

    DEFF Research Database (Denmark)

    Chan, Kara; Prendergast, Gerard

    2009-01-01

    Purpose - The purpose of this paper is to explore Chinese adolescents' perceptions of healthy eating, their perceptions of various socializing agents shaping their eating habits, and their opinions about various regulatory measures which might be imposed to encourage healthy eating. Design/methodology/approach - Four focus group interview sessions were conducted with 22 eighth and ninth grade adolescents (aged 13 to 15) in Hong Kong. Findings - The participants perceived a balanced diet and regular meal times as the most important attributes of healthy eating. Participants were most likely to eat unhealthy food at parties, during festivals, and when socializing. They reported that mothers and teachers often advise them to eat healthy foods. They felt that banning the sale of soft drinks in schools and at sports centers and/or increasing the price of soft drinks might discourage their consumption, but felt that banning soft drink advertisements and/or making free drinking water more available would be ineffective. Research limitations/implications - The interviewees were mostly from low to middle income families. They may not be representative of all adolescents in Hong Kong or elsewhere, thus limiting the generalisabilty of the findings. Originality/value - The study serves as a guideline for social services marketing professionals targeting adolescents. Social services marketers might consider influencing adolescents' eating habits through the parents and school teachers. Restricting selling of soft drinks at schools and sports centers and increasing the price of soft drinks should be considered, as these were considered relatively more effective than other measures. Seven testable hypotheses are proposed to guide further research.

    2011-05-01

    The aim of this study was to identify factors influencing edentulous patients' preferences for treatment using conventional or implant dentures (ID). A consecutive sample of 112 patients was selected in a university facility. All patients responded to a questionnaire concerning preferences about treatment and factors influencing preferences for conventional complete dentures (CD), implant-retained overdentures (IRO) and fixed implant-supported prostheses (FISP). Subsequently, a set of 21 questions was presented, and patients were requested to rate the importance of various potential reasons influencing their choice of treatment. Preference for CD was more prevalent for maxilla (52·7%) and mandible (41·1%). Fixed implant-supported prostheses and IRO were preferred for the mandible (FISP=37·5%; IRO=21·4%) rather than maxilla (FISP=27·7%; IRO=19·6%). The most preferred treatment option among the subjects when evaluating both arches was the implant-supported fixed or removable prosthesis (FISP/IRO). A preference for combined upper and lower CD was also commonly reported (39·3%). Factor analysis identified six components that accounted for 72·2% of the total variance: (i) psychosocial benefits, (ii) functional performance, (iii) technical and financial concerns, (iv) post-insertion complaints, (v) removability and (vi) longevity. Technical and financial concerns (cost, complexity, surgery risks and duration of treatment) were more relevant for those who preferred ID (P<0·001). With the exception of post-insertion complaints, all mean scores of component factor loadings were positive for ID. Conventional complete dentures are associated with lower expected outcomes by patients, and cost-related issues are the major factors associated with the preferences for implant treatment of edentulous patients.

    Full Text Available Definitions of spinal cord injury agree in the consequences of that injury is the loss in varying degrees of autonomic function; this will cause a change in the lifestyle of patients and their families.In the spinal injury, the priority is the recovery or maintenance of vital organ functions, the physical stabilization for people. Later, the priority here is the rehabilitation and adaptation. This should be integrated at all levels, physical, psychological and social. Confrontation is, by Callista Roy, a important variable for understanding the effect of stress on health and disease, health maintenance or recovery. The way, that the patients have to confront the disease, are the confrontation strategies. They are defined as thoughts and actions that persons put in place to deal with adverse changes. They are grouped into 3 categories: problems, emotions and avoidance.There are others factors that influence in the use of strategies, between them the personality. According to Eysenck this is determined by the functional interaction of four factors: cognitive (intelligence, conative (character, affective (temperament and somatic (construction. With this study we want to know the factors that influence in the confrontation of the spinal cord injury and to analyze the possible relation between them, and to be able to elaborate particular tools, on the most determinant factors, to obtain an effective confrontation about this type of disease.

  19. Advances in principal factors influencing carbon dioxide adsorption on zeolites

    International Nuclear Information System (INIS)

    We report the advances in the principal structural and experimental factors that might influence the carbon dioxide (CO2) adsorption on natural and synthetic zeolites. The CO2 adsorption is principally govern by the inclusion of exchangeable cations (countercations) within the cavities of zeolites, which induce basicity and an electric field, two key parameters for CO2 adsorption. More specifically, these two parameters vary with diverse factors including the nature, distribution and number of exchangeable cations. The structure of framework also determines CO2 adsorption on zeolites by influencing the basicity and electric field in their cavities. In fact, the basicity and electric field usually vary inversely with the Si/Al ratio. Furthermore, the CO2 adsorption might be limited by the size of pores within zeolites and by the carbonates formation during the CO2 chemisorption. The polarity of molecules adsorbed on zeolites represents a very important factor that influences their interaction with the electric field. The adsorbates that have the most great quadrupole moment such as the CO2, might interact strongly with the electric field of zeolites and this favors their adsorption. The pressure, temperature and presence of water seem to be the most important experimental conditions that influence the adsorption of CO2. The CO2 adsorption increases with the gas phase pressorption increases with the gas phase pressure and decreases with the rise of temperature. The presence of water significantly decreases adsorption capacity of cationic zeolites by decreasing strength and heterogeneity of the electric field and by favoring the formation of bicarbonates. The optimization of the zeolites structural characteristics and the experimental conditions might enhance substantially their CO2 adsorption capacity and thereby might give rise to the excellent adsorbents that may be used to capturing the industrial emissions of CO2.

    Koci, Peter

    The research conducted for this dissertation examined the learning environment of a specific high school program that delivered the explicit curriculum through an integrated experiential manner, which utilized field and outdoor experiences. The program ran over one semester (five months) and it integrated the grade 10 British Columbian curriculum in five subjects. A mixed methods approach was employed to identify the students' perceptions and provide richer descriptions of their experiences related to their unique learning environment. Quantitative instruments were used to assess changes in students' perspectives of their learning environment, as well as other supporting factors including students' mindfulness, and behaviours towards the environment. Qualitative data collection included observations, open-ended questions, and impromptu interviews with the teacher. The qualitative data describe the factors and processes that influenced the learning environment and give a richer, deeper interpretation which complements the quantitative findings. The research results showed positive scores on all the quantitative measures conducted, and the qualitative data provided further insight into descriptions of learning environment constructs that the students perceived as most important. A major finding was that the group cohesion measure was perceived by students as the most important attribute of their preferred learning environment. A flow chart was developed to help the researcher conceptualize how the learning environment, learning process, and outcomes relate to one another in the studied program. This research attempts to explain through the consideration of this case study: how learning environments can influence behavioural change and how an interconnectedness among several factors in the learning process is influenced by the type of learning environment facilitated. Considerably more research is needed in this area to understand fully the complexity learning environments and how they influence learning and behaviour. Keywords: learning environments; integrated experiential programs; environmental education.

    2013-11-01

    Shaping of self-perception is among others influenced by physical, interpersonal, emotional, and cultural factors. In self-perception of overweight people an important role is played by interpersonal factors, which include the opinions of others and the relationship with the surrounding. The evaluation of the body image is also affect by sociocultural factors including the media, which create an unrealistic and impossible to achieve ideal of beauty. Contemporary ideal of beauty, where a slim figure is dominant, more frequently contributes to the occurrence of discrimination and stigmatization of overweight people. This phenomenon causes negative self-perception leading to the occurrence of such emotional problems as low self-esteem, lack of confidence, depression and anxiety disorders. Overweight children and adolescents are also frequently stigmatized and discriminated because of their body weight, which results in the development of a negative body image that may lead to low self-esteem and symptoms of depression.

    2013-01-01

    Eating disorders, which include anorexia nervosa, bulimia nervosa, and eating disorder not otherwise specified, are psychiatric disorders with physical complications. Several factors may contribute to the onset of anorexia nervosa and bulimia nervosa, including a familial predisposition to these disorders as well as individual personality characteristics. Dissatisfaction with body shape and an overwhelming desire to be thin are considered as risk factors for the development of eating disorders. Skin signs are the expression of the medical consequences of starvation, vomiting, abuse of drugs, such as laxatives and diuretics, and psychiatric morbidity. They include xerosis, lanugolike body hair, telogen effluvium, carotenoderma, acne, hyperpigmentation, seborrheic dermatitis, acrocyanosis, perniosis, petechiae, livedo reticularis, interdigital intertrigo, paronychia, acquired striae distensae, and acral coldness. The most characteristic cutaneous sign of vomiting is Russell sign (knuckle calluses). Symptoms due to laxative or diuretic abuse include adverse reactions to drugs. Symptoms due to psychiatric morbidity (artefacta) include the consequences of self-induced trauma. The role of the dermatologist in the management of eating disorders is to make an early diagnosis of the "hidden" signs of eating disorders in patients who tend to minimize or deny their disorder.

    Full Text Available O comportamento alimentar ocupa atualmente um papel central na prevenção e no tratamento de doenças. A alimentação durante a infância, ao mesmo tempo em que é importante para o crescimento e desenvolvimento, pode também representar um dos principais fatores de prevenção de algumas doenças na fase adulta. Freqüentemente a família, os fatores sociais e os ambientais podem influenciar o padrão alimentar das crianças. O objetivo desta revisão foi abordar os diversos fatores ambientais envolvidos na aquisição de hábitos alimentares na infância. Os artigos selecionados foram pesquisados nas bases de dados Medline e SciELO considerando o período de 1978 a 2007. Foram utilizados os termos em ingles: children's eating patterns, children's dietary quality, determinants of children's eating patterns e em português.

    Monitoring athletic preparation facilitates the evaluation and adjustment of practices to optimize performance outcomes. Self-report measures such as questionnaires and diaries are suggested to be a simple and cost-effective approach to monitoring an athlete's response to training, however their efficacy is dependent on how they are implemented and used. This study sought to identify the perceived factors influencing the implementation of athlete self-report measures (ASRM) in elite sport settings. Semi-structured interviews were conducted with athletes, coaches and sports science and medicine staff at a national sporting institute (n = 30). Interviewees represented 20 different sports programs and had varying experience with ASRM. Purported factors influencing the implementation of ASRM related to the measure itself (e.g., accessibility, timing of completion), and the social environment (e.g., buy-in, reinforcement). Social environmental factors included individual, inter-personal and organizational levels which is consistent with a social ecological framework. An adaptation of this framework was combined with the factors associated with the measure to illustrate the inter-relations and influence upon compliance, data accuracy and athletic outcomes. To improve implementation of ASRM and ultimately athletic outcomes, a multi-factorial and multi-level approach is needed. Key pointsEffective implementation of a self-report measure for monitoring athletes requires a multi-factorial and multi-level approach which addresses the particular measure used and the surrounding social environment.A well-designed self-report measure should obtain quality data with minimal burden on athletes and staff.A supportive social environment involves buy-in and coordination of all parties, at both an individual and organization level.

    2012-10-01

    Increased consumption, larger scale production and more efficient distribution of fresh produce over the past two decades have contributed to an increase in the number of illness outbreaks caused by this commodity. Pathogen contamination of fresh produce may originate before or after harvest, but once contaminated produce is difficult to sanitize. The prospect that some pathogens invade the vascular system of plants and establish "sub-clinical" infection needs to be better understood to enable estimation of its influence upon risk of human illness. Conventional surface sanitation methods can reduce the microbial load, but cannot eliminate pathogens if present. Chlorine dioxide, electrolyzed water, UV light, cold atmospheric plasma, hydrogen peroxide, organic acids and acidified sodium chlorite show promise, but irradiation at 1 kGy in high oxygen atmospheres may prove to be the most effective means to assure elimination of both surface and internal contamination of produce by pathogens. Pathogens of greatest current concern are Salmonella (tomatoes, seed sprouts and spices) and Escherichia coli O157:H7 on leafy greens (spinach and lettuce). This review considers new information on illness outbreaks caused by produce, identifies factors which influence their frequency and size and examines intervention effectiveness. Research needed to increase our understanding of the factors influencing microbial safety of fresh produce is addressed. PMID:22850369

    Full Text Available The contribution deals with the process monitoring based on www technologies. It also researches the influence of clients? number and the network transfer rate on the process monitoring quality. The process monitoring is realized by the distributed application. The server part of application (written in Delphi acquires actually measured data and sends them through the socket communication channel to the client. The client part of application is realized as applet (written in Java, which receives data from the server and executes their processing. There are some factors influencing the quality of the client?server communication on the server and client side, such as the number of running tasks, exploitation of system recourses, number of connected clients and network rate. Their influences are presented in graphical form. The first course represents a monitored signal, the second the accuracy of server?s time sending, the third the accuracy of client?s receiving and the fourth the duration of the packet transfer between the client and server. The computer working as a server is marked as S, the client is marked as K. The influence of client quality showed that the usable sample period is about 0.1s. By the study of quality of server S1 the applicable sample period 0.17s was specified. For shorter sample periods, the client isn?t capable to process received data and so occurs data buffering, which causes the time shift concerning to signal on server side. In this area monitoring is not desirable. The influence of client number showed that in the same time can correctly operate 19 to 33 clients at sample periods 0.085s to 0.33s. The influence of transfer rate showed applicability of monitoring so for local as for remote distances of clients.

    Full Text Available Background Parasomnias are undesirable events occurring in the sleep-wake transition period. Several predisposing factors are reported to induce parasomnia in preschool children. Objective To estimate the magnitude of parasomnia in school children and to evaluate its relationship with possible predisposing factors. Methods Five hundred children aged 5-16 years from a boys’ school and a girls’ school in Khulna City, Bangladesh, were randomly selected for the study conducted from July to December 2011. The survey was done in two steps: self-administered questionnaire and clinical interviews of affected students and their parents. Apart from demographic features, questionnaires included details of perinatal and personal factors as well as familial and socioeconomic factors. The diagnoses of variants of parasomnias was based on the criteria for category-based classification by the American Academy of Sleep Mmedicine. Results Seven hundred thirteen filled questionnaires revealed parasomnia in 187 (26.2% children. Most parasomnias were accompanied by other sleep disorders, in which 23 (12.3% having primary dyssomnias including 18 (9.3% obstructive sleep apnea, and 10 (5.3% parasomnias with hypersomnias. Nightmares (7.4% were highest among the parasomnias followed by nocturnal enuresis (4.1% and sleep terrors (3.4%. More girls experienced parasomnias than boys (107/360 vs. 80/353, respectively; P=0.039. Perinatal factors such as problems during pregnancy (17.1% or eventful delivery (25.7%, and socioeconomic factors such as familial disharmony (11.8% and low socioeconomic level (31.6% had positive associations with parasomnia. Conclusion One-quarter of school children experience parasomnia. We found perinatal factors particularly problem during pregnancy, and socioeconomic factors particularly familial disharmony have significant influences on this condition.

    Full Text Available The main purpose of the paper is to determine the correlation of consumers’ demographic or socioeconomic characteristics and individual difference factors on the impulse buying behavior with respect to a number of single impulsivity indicators and one collective indicator. The paper consists of theoretical and research aspects. The first part encompasses theoretical insights into the secondary research regarding impulse buying while the practical part presents the methodology and primary research results. With respect to the subject matter, research goals as well as previous findings and primary research results, corresponding hypotheses were set and mainly confirmed. The results showed that demographic factors, such as the age and working status, are related to most impulse buying indicators and to the impulsivity collective indicator. However, household income produced opposite results. Household income proved to have no major influence on the majority of impulse buying indicators but to be related noticeably to the collective impulsivity indicator, indicating that this result should be regarded with caution. Research results also pointed to the fact that the majority of individual indicators (innovativeness, tendency to the fashionable and shopping enjoyment are positively and negatively related to the impulse buying behavior and that individual difference factors have a greater influence on impulse buying than do demographic characteristics. The paper also summarizes research limitations as well as the work contribution and future research guidelines.

  16. Factors influencing quality of bowel preparation for colonoscopy

    2013-01-01

    Full Text Available Recent technological advances in colonoscopy have led to improvements in both image enhancement and procedural performance. However, the utility of these technological advancements remain dependent on the quality of bowel preparation during colonoscopy. Poor bowel preparation has been shown to be associated with lower quality indicators of colonoscopy performance, such as reduced cecal intubation rates, increased patient discomfort and lower adenoma detection. The most popular bowel preparation regimes currently used are based on either Polyethylene glycol-electrolyte, a non-absorbable solution, or aqueous sodium phosphate, a low-volume hyperosmotic solution. Statements from various international societies and several reviews have suggested that the efficacy of bowel preparation regimes based on both purgatives are similar, although patients’ compliance with these regimes may differ somewhat. Many studies have now shown that factors other than the type of bowel preparation regime used, can influence the quality of bowel preparation among adult patients undergoing colonoscopy. These factors can be broadly categorized as either patient-related or procedure-related. Studies from both Asia and the West have identified patient-related factors such as an increased age, male gender, presence of co-morbidity and socio-economic status of patients to be associated with poor bowel preparation among adults undergoing routine out-patient colonoscopy. Additionally, procedure-related factors such as adherence to bowel preparation instructions, timing of bowel purgative administration and appointment waiting times for colonoscopy are recognized to influence the quality of colon cleansing. Knowledge of these factors should aid clinicians in modifying bowel preparation regimes accordingly, such that the quality of colonoscopy performance and delivery of service to patients can be optimised.

    Full Text Available CONTEXT: The natural history of pancreatic pseudocysts has become well known in recent years, but the choice of a proper treatment still remains controversial. OBJECTIVE: This study aims at establishing whether predictive factors influencing therapeutic outcomes exist. SETTING: Patients with pancreatic pseudocysts following an episode of acute pancreatitis treated from January 1980 to December 2001 at the Department of General Surgery and Organ Transplantation of the University of Parma, Italy. PATIENTS: Seventy-four patients were studied: 12 had a spontaneous resolution, 37 patients were treated surgically, 15 were treated endoscopically and in 10, percutaneous drainage was used. MAIN OUTCOME MEASURES: Epidemiological, clinical and pathological characteristics of patients with pancreatic pseudocysts were related to morbidity, recurrence rates and hospital stay. RESULTS: At univariate logistic regression, our data reveal a significant increase in morbidity related to age (P=0.013, etiology (alcoholic vs. biliary, P=0.024, Ranson score of previous pancreatitis (P=0.006, nutritional assessment (P=0.001, residual necrosis (P<0.001 and modality of treatment (P=0.009, whereas none of these parameters has been shown to be significantly correlated to recurrence. At multivariate logistic regression, only residual necrosis was significantly related to morbidity. CONCLUSIONS: Some factors, such as epidemiological (age, etiology, clinical (severity of previous pancreatitis, malnourishment, pathological (residual necrosis, and therapeutical factors (emergency/urgency treatment are predictive of worse outcomes for invasive treatment of pseudocysts. In particular residual necrosis appeared to be the most important factor influencing invasive treatment outcomes, confirming that this pathological aspect deserves particular attention from surgeons. No risk factors predicting pancreatic pseudocyst recurrence emerged.

    2011-09-01

    Full Text Available With constantly changing environmental selection pressures, retroviruses rely upon recombination to reassort polymorphisms in their genomes and increase genetic diversity, which improves the chances for the survival of their population. Recombination occurs during DNA synthesis, whereby reverse transcriptase undergoes template switching events between the two copackaged RNAs, resulting in a viral recombinant with portions of the genetic information from each parental RNA. This review summarizes our current understanding of the factors and mechanisms influencing retroviral recombination, fidelity of the recombination process, and evaluates the subsequent viral diversity and fitness of the progeny recombinant. Specifically, the high mutation rates and high recombination frequencies of HIV-1 will be analyzed for their roles in influencing HIV-1 global diversity, as well as HIV-1 diagnosis, drug treatment, and vaccine development.

    The present review concentrates on environmental factors which influence the outcome of peptic ulcer disease by acting from the outside. Endogenous risk factors, such as acid output, pepsin secretion and serum pepsinogen, gastritis and mucosal defense, blood group, and secretor status, are only dealt with when they help to explain the mechanism by which exogenous risk factors affect the upper gastrointestinal mucosa. After outlining the wax and wane of peptic ulcer, it is concluded that these changes resulted from similar temporal patterns of occupational workload in the general population. Cross sectional studies also support the contention of occupational workload being a risk factor in peptic ulcer, explaining several characteristic features of peptic ulcer, such as its sex, race, and social class distribution, increased incidence in immigrant workers, seasonal variation, healing by bed rest, and urban versus rural distribution. Susceptible subjects may react to a rise in occupational workload and acute exposure to stressful life events by increased gastric secretion which, in turn, leads to ulceration and symptoms. Cigarette smoking, intake of aspirin and related drugs, dietary salt, and alcohol abuse represent additional environmental risk factors, which form the etiologic link of the association of peptic ulcer with chronic lung disease, rheumatoid arthritis, hypertensive disease, and liver cirrhosis, respectively.

    INTRODUCTION: Irish general surgery faces a recruitment crisis with only 87 of 145 (60%) basic surgical training (BST) places filled in 2009. We assessed basic surgical trainees to identify objective, and potentially modifiable, factors that influence ultimate recruitment into a general surgical career. METHODS: Candidates commencing BST training during a 5-year period between 2004 and 2008 were included in a quantitative study. In addition a total of 2,536 candidates, representing all those who commenced surgical training in Ireland since 1960 were identified through the Royal College of Surgeons in Ireland (RCSI) database and invited to complete an online survey. Statistical analysis was performed using SPSS version 15, with p < 0.05 considered significant. RESULTS: During the 5-year quantitative study period there were 381 BST trainees. Gender was a significant predictor of career choice with women more likely to ultimately choose a nonsurgical career after initial surgical training (p = 0.049). Passing surgical membership examinations (MRCS) also was predictive of remaining in surgery (p = 0.005). Training region was not a significant predictor of ultimate career choice. There were 418 survey respondents. The influence of role models was most commonly cited as influencing candidates in choosing to commence surgical training. Candidates who rated "academic opportunity" (p = 0.023) and "intellectual challenge" (p = 0.047) as factors that influenced their decision to commence surgical training were more likely to ultimately continue their careers in a surgical speciality. CONCLUSIONS: This study describes the career pathway of surgical trainees and confirms the importance of academic achievement in discriminating between candidates applying for surgical training schemes.

    Full Text Available The needs to develop improved varieties of maize have been in the heart of various researchers and institutions in Nigeria because of its strategic role in tackling food insecurity and poverty. Despite substantial efforts to improve maize varieties, the level of adoption of improved maize varieties (IMV in Nigeria in still very low. Although previous adoption studies have indicated a number of socioeconomic and institutional/organizational variables as important factors influencing adoption of improved maize (crop varieties in the country, whether these factors are the main issues of concern, and whether the inclusion of regional/agro-ecological variables in adoption model are also important in explaining what could drive farmers’ adoption behaviour requires investigation. This study therefore examined factors influencing adoption of IMV among farmers in Nigeria using a selected portion of the Nigeria Living Standard Measurement Survey data collected by the National Bureau of Statistics and the World Bank for 2010/2011 cropping season with descriptive statistics and probit model as tools for data analysis. The results suggest, in line with some previous studies, that farm size, education level of farmers and access to extension services would significantly influence adoption of IMV. The results also indicate that farmers across the entire agro-ecological regions of country share some negative sentiments regarding adoption of IMV. Renewed emphasis on interventions that would enable farmers gain more access to farmland, and promote formal education and extension service are advocated. An attempt to incorporate variables that capture farmers’ perception/experience on agroclimatic/ ecologically related concerns in adoption study could aid better understand of what drives farmers’ adoption decisions across the country especially in the light of the emerging climate change issues and its implication on food production.

    Dengue fever is a debilitating and infectious disease that could be life-threatening. It is caused by the dengue virus which affects millions of people in the tropical area. Currently, there is no cure for the disease as there is no vaccine available. Thus, prevention of the vector population using conventional methods is by far the main strategy but has been found ineffective. A genetically modified (GM) mosquito is among the favoured alternatives to curb dengue fever in Malaysia. Past studies have shown that development and diffusion of gene technology products depends heavily upon public acceptance. The purpose of this study is to identify the relevant factors influencing stakeholders' attitudes toward the GM Aedes mosquito and to analyse the relationships between all the factors using the structural equation model. A survey was carried out on 509 respondents from various stakeholder groups in the Klang Valley region of Malaysia. Results of the survey have confirmed that public perception towards complex issues such as gene technology should be seen as a multi-faceted process. The perceived benefit-perceived risk balance is very important in determining the most predominant predictor of attitudes toward a GM mosquito. In this study the stakeholders perceived the benefit of the GM mosquito as outweighing its risk, translating perceived benefit as the most important direct predictor of attitudes toward the GM mosquito. Trust in key players has a direct influence on attitudes toward the GM mosquito while moral concern exhibited an indirect influence through perceived benefits. Other factors such as attitudes toward technology and nature were also indirect predictors of attitudes toward the GM mosquito while religiosity and engagement did not exhibited any significant roles. The research findings serve as a useful database to understand public acceptance and the social construct of public attitudes towards the GM mosquito to combat dengue. PMID:24906652

Constructs showing significant correlation to an individual’s attitude toward digital piracy were age, Machiavellianism, cognitive beliefs, positive affective beliefs and perceived importance. Interestingly, no gender influence was found. The paper concludes with practical suggestions for South African educational, government and business institutions to reduce digital piracy based on our findings.

    Factors influencing the development of evidence-based nursing practice (EBNP) were examined in Prince Edward Island, Canada. An adapted electronic questionnaire was distributed to practicing registered nurses and nurse practitioners (n=68). An analysis of variance revealed a significant difference between nurses' clinical practice setting and the EBNP scale. Significant differences were also found between age and education level when compared with the EBNP subscales where novice nurses were less likely to rely on experience and intuition, and expert nurses with a higher level of education reported being more skilful at synthesising and applying information from research findings into their nursing practice.

    Full Text Available Having loyal customer is the primary objective of any business owner since loyal customers purchase on regular basis, create sustainable growth and reduce risk of bankruptcy. During the past few years, many people argue that customer loyalty must be established through ethical values. In this paper, we present an empirical investigation to detect ethical factors influencing customer loyalty. The proposed study determines five criteria including customer repurchase, interest in brand, recommending brand to others, positive attitude toward brand and cognitive loyalty to brand. These criteria have been ranked using fuzzy analytical network process. The study determines 14 different ethical values, which may play essential role on customer loyalty and using VIKOR, different ethical values are ranked. The study indicates that welcoming customers is the most important factor followed by cheerfulness, on time delivery, being informative and having appropriate standards.

  19. Studies on influence of biological factors on concentration of radionuclides

    International Nuclear Information System (INIS)

    Biological factors influencing the concentration of radionuclides were studied from the points of uptake through digestive tract, food as pathways, and metabolic activities. The uptake of radionuclides by marine fishes through digestive tract was determined by whole body counter. 137Cs, 65Zn, 131I, 54Mn, 60Co, 85Sr, and 144Ce were used as tracers and was given with solid feed. The feed given was excreated 24 to 48 hours later in small of middle sized fishes, and 20 to 48 hours later in large sized fishes. The uptake rate of 137Cs and 65Zn was high absorption of 20 to 80 per cent, that of 131I, 60Co and 54Mn was not remarkable, and that of 85Sr and 144Ce was low absorption. The biological concentration of 137Cs through pathways of food. In fishes taking up radionuclides through contaminated food, concentration factor increased in accordance with contamination level. In addition, radionuclides with small uptake but delayed excretion and those with high concentration rate could be the factors to decide the concentration factors of marine organisms. In order to study the relationship between metabolic activities and concentration, the uptake of one-year old fishes and adult fishes, and fishes fed and those non-fed were compared. One-year fishes took up large amount of 85Sr during short period, however, concentration by metabolism in adult fishes was slow. Comparing feeding group and non-feeding group, the former showed 85Sr concentration factor of 1.5 to 2 times that of the later, and the later showed 137Cs concentration factor of 2 to 4 times that of the former. However, both uptake and excretion were rapid suggesting that taking food activated the metabolism of substances. (Kanao, N.)

    Food and eating environments likely contribute to the increasing epidemic of obesity and chronic diseases, over and above individual factors such as knowledge, skills, and motivation. Environmental and policy interventions may be among the most effective strategies for creating population-wide improvements in eating. This review describes an ecological framework for conceptualizing the many food environments and conditions that influence food choices, with an emphasis on current knowledge regarding the home, child care, school, work site, retail store, and restaurant settings. Important issues of disparities in food access for low-income and minority groups and macrolevel issues are also reviewed. The status of measurement and evaluation of nutrition environments and the need for action to improve health are highlighted. PMID:18031223

  1. Particle deposition in indoor environments: analysis of influencing factors.

    Zhao, Bin; Wu, Jun

    2007-08-17

    In this paper, several factors influencing particle deposition in indoor environments are analyzed with an analytical model and a three-dimensional drift flux model combined with the particle deposition boundary conditions for wall surfaces. The influences of flow conditions near the wall surfaces, surface roughness and particle concentration distribution on particle deposition indoors are studied. By modeling particle deposition onto surfaces with the analytical model, it is found that larger friction velocity near the wall surfaces and rougher surface may lead to larger particle deposition velocity when the particle size is small, but when particle size is large enough (the range is up to the actual friction velocity and in this study it is about 1-5 microm), the influence of the friction velocity and roughness could be neglected. Furthermore, the three-dimensional numerical simulations indicate that particle concentration distribution may be very different even for the same particle source and air change rate, which cause a different deposited particle flux. As the particle concentration distribution may not be uniform in most cases, especially for the ventilated rooms, it is important to incorporate particle concentration distribution when analyzing particle deposition in indoor environments. Some suggestions or rules for particle deposition controlling are also presented based on the analysis. PMID:17280778

    Groundwater drought is a specific type of drought that concerns groundwater bodies. It may have a significant adverse effect on the socio-economic, agricultural, and environmental conditions. Investigating the effect of response different climatic and manmade factors on groundwater drought provides essential information for sustainable planning and management of water resources. The aim of this study is to identify the influencing factors on groundwater drought in a drought prone region in Bangladesh to understand the forcing mechanisms. The Standardised Precipitation Index (SPI) and Reconnaissance Drought Index (RDI) have been used to quantify the aggregated deficit between precipitation and the evaporative demand of the atmosphere. The influence of land use patterns on the groundwater drought has been identified by calculating spatially distributed groundwater recharge as a function of land use. The result shows that drought intensity is more severe during the dry season (November to April) compared to the rainy season (May to October). The evapotranspiration and rainfall deficit has a significant effect on meteorological drought which has a direct relation with groundwater drought. Urbanization results in a decrease of groundwater recharge which increases groundwater drought severity. Overexploitation of groundwater for irrigation and recurrent meteorological droughts are the main causes of groundwater drought in the study area. Efficient irrigation management is essential to reduce the growing pressure on groundwater resources and ensure sustainable water management. More detailed studies on climate change and land use change effects on groundwater drought are recommended.

  3. Particulate pollution in ventilated space: Analysis of influencing factors

    International Nuclear Information System (INIS)

    Particle pollution has been identified to be a major indoor air pollution problem as many epidemiologic evidences have indicated that the particle exposure affects the occupant health. In common practice, mechanical ventilation is introduced to maintain a satisfactory indoor air quality for the occupant, which includes the area of particle control within the space. In order to have an effective control to the indoor particle pollution, it is important to understand the major factors influencing the indoor particle concentration in the breathing zone. This study employs a previously proposed approach to study the particle pollution in a typical ventilation system. The model simultaneously takes into account the interactions between particle transport in ventilation ducts and rooms and particle spatial distribution. It has been proven that an entire ventilation system, including filters, ducts and rooms, can be regarded as a serial of filters in steady-state cases, hence the name 'particle filter group model'. The particle concentration in the breathing zone is calculated under different conditions, and the result is then validated by experimental data. Based on the results, four main factors that affect the particle concentration in the breathing zone are identified, they are fresh air rate, particle filter efficiency, the type of the ventilation duct (roughness) and ventilation modes. Their degrees of influence are analyzed and then the possible measures to improve/cod then the possible measures to improve/control the indoor particle pollution are suggested

    Placental Growth Factor (PGF) is a key molecule in angiogenesis. Several studies have revealed an important role of PGF primarily in pathological conditions (e.g.: ischaemia, tumour formation, cardiovascular diseases and inflammatory processes) suggesting its use as a potential therapeutic agent. However, to date, no information is available regarding the genetics of PGF variability. Furthermore, even though the effect of environmental factors (e.g.: cigarette smoking) on angiogenesis has been explored, no data on the influence of these factors on PGF levels have been reported so far. Here we have first investigated PGF variability in two cohorts focusing on non-genetic risk factors: a study sample from two isolated villages in the Cilento region, South Italy (N=871) and a replication sample from the general Danish population (N=1,812). A significant difference in PGF mean levels was found between the two cohorts. However, in both samples, we observed a strong correlation of PGF levels with ageing and sex, men displaying PGF levels significantly higher than women. Interestingly, smoking was also found to influence the trait in the two populations, although differently. We have then focused on genetic risk factors. The association between five single nucleotide polymorphisms (SNPs) located in the PGF gene and the plasma levels of the protein was investigated. Two polymorphisms (rs11850328 and rs2268614) were associated with the PGF plasma levels in the Cilento sample and these associations were strongly replicated in the Danish sample. These results, for the first time, support the hypothesis of the presence of genetic and environmental factors influencing PGF plasma variability.

    Full Text Available Context: The total time spent in nursing care depends on the type of patient and the patient?s condition. We analysed factors that influenced the time spent in nursing a patient. Aims : To analyse the factors in a patient?s condition that influenced time spent in nursing a patient. Materials and Methods: This study was performed in the Surgical Intensive Care Unit of a tertiary referral centre, over a period of one month. The total time spent on a patient in nursing care for the first 24 hours of admission, was recorded. This time was divided into time for routine nursing care, time for interventions, time for monitoring and time for administering medications. Statistical analysis used: A backward stepwise linear regression analysis using the age, sex, diagnosis, type of admission and ventilatory status as variables, was done. Results: Patients admitted after elective surgery required less time (852.4 ± 234.1 minutes, than those admitted after either emergency surgery (1069.5 ± 187.3 minutes, or directly from the ward or the emergency room (1253.7 ± 42.1 minutes. Patients who were ventilated required more time (1111.5 ± 132.5 minutes, than those brought on a T-piece (732.2 ± 134.8 minutes or extubated (639.5 ± 155.6 minutes. The regression analysis showed that only the type of admission and the ventilatory status significantly affected the time. Conclusions : This study showed that the type of admission and ventilatory status significantly influenced the time spent in nursing care. This will help optimal utilization of nursing resources.

    Patients can acutely deteriorate unexpectedly. Junior medical officers (JMOs) are often first to review patients who become unwell. Opportunities to escalate care to a senior colleague may exist prior to the need for a rapid response team review. Little is known about the factors that influence JMO decisions to escalate care. In this study, our objective was to investigate the self-reported factors that influence escalation of care by JMOs in a university-affiliated, tertiary level hospital. We designed a face-to-face questionnaire of JMOs using standardised introduction to minimise interviewer bias. Fifty JMOs participated in the study (a 100% response rate). Most (63.3%) felt that they would be able to identify a clinically deteriorating patient. They would be more likely to escalate care if they were not familiar with the patient's clinical problem. If handover plans were seen to be adequate, JMOs felt it was less necessary to escalate care. Few JMOs (12%) agreed that they limited escalation due to fear of criticism or fear of conflict with senior medical staff. Although 36% agreed that they were concerned about waking seniors overnight, only 6% feared that escalating care overnight would affect their future career prospects. Escalation of care appears to be mostly influenced by the confidence and familiarity of the JMO with the cause of deterioration. JMOs identified clear handover with documented goals of treatment and suggested actions in event of clinical deterioration as the best means by which to improve the process of escalation of care for clinically deteriorating patients.

    Full Text Available Aims: The aim of this study was detecting the dietary habits and some influencing factors in Erciyes University students at 3rd and 4th grades. Materials and method: Nine departments were chosen among 27 departments of ten faculties and higher education institutes of Erciyes University by 1/3 randomization. Face-to-face conversation was made with '599 out of 650 students- studying at 3rd and 4th grades. An interviewing form consisting of 30 questions about dietary habits and attitudes was applied to these students. Results: A total of 394 female (65,8%, and 205 male (34,2% students were recruited. There was a significant difference regarding smoking between, female and male students. Mean body mass index in females was 20,77+2,06 kg/m2 and 22,70+2,33 kg/m1 in males. While the number of students having three meals per day regularly was 293 (48,9%, the number of students having breakfast was 206 (34,4%. However 251 (41,9% of the students stated that they had lunch and, 450 (75,1% stated that they had dinner regularly. It was apparent that students living with their f amilies or friends and the ones participated voluntarily to conferences about diet had lunch and dinner regularly. Male students had lunch more regularly compared to female students. Conclusion: Our data revealed that students often miss meals, have breakfast regularly if they live with their families/friends and dinner is the meal they miss as the least. The evaluation of this data suggested .that students often miss meals, have regular breakfast if they live at home and dinner is the most regular meal among them. On the other hand activities like conferences with participation on a voluntary basis appeared to be more effective than previous obligatory lectures on the eating habits of the studenst.

    The purpose of this study was to test the impact of two variables on post-binge eating negative emotion in a combined sample of women with anorexia nervosa (AN; n = 47) and bulimia nervosa (BN; n = 121). Participants completed two weeks of an ecological momentary assessment protocol during which they provided multiple daily ratings of overall negative affect and guilt and reported eating disorder behaviors including binge eating and self-induced vomiting. The results indicate that both overall negative affect and guilt exhibited a statistically significantly decrease in the hour immediately following binge eating episodes. The decrease in guilt, but not overall negative affect, was moderated by eating disorder diagnosis and the tendency to engage in self-induced vomiting. Specifically, individuals with BN reported a greater reduction in guilt than those with AN, and individuals who did not typically engage in self-induced vomiting reported more decreases in guilt than those who typically engaged in self-induced vomiting. This study extends the existing literature on the relationship between negative affect and eating disorder behaviors, suggesting guilt as a potentially relevant facet of negative affect in the maintenance of binge eating. In addition, the findings indicate that two individual differences, eating disorder diagnosis and self-induced vomiting, may influence the trajectory of guilt following binge eating episodes.

  13. Factors influencing predation on juvenile ungulates and natural selection implications

    S. M. Barber-Meyer

    2008-06-01

    Full Text Available Juvenile ungulates are generally more vulnerable to predation than are adult ungulates other than senescent individuals, not only because of their relative youth, fragility, and inexperience, but also because of congenital factors. Linnell et al.’s (Wildl. Biol. 1: 209-223 extensive review of predation on juvenile ungulates concluded that research was needed to determine the predisposition of these juveniles to predation. Since then, various characteristics that potentially predispose juvenile ungulates have emerged including blood characteristics, morphometric and other condition factors, and other factors such as birth period, the mother’s experience, and spatial and habitat aspects. To the extent that any of the physical or behavioral traits possessed by juvenile ungulates have a genetic or heritable and partly independent epigenetic component that predisposes them to predation, predators may play an important role in their natural selection. We review the possible influence of these characteristics on predisposing juvenile ungulates to predation and discuss natural selection implications and potential selection mechanisms. Although juvenile ungulates as a class are likely more vulnerable to predation than all but senescent adults, our review presents studies indicating that juveniles with certain tendencies or traits are killed more often than others. This finding suggests that successful predation on juveniles is more selective than is often assumed. Because we are unable to control for (or in some cases even measure the myriad of other possible vulnerabilities such as differences in sensory abilities, intelligence, hiding abilities, tendency to travel, etc., finding selective predation based on the relatively few differences we can measure is noteworthy and points to the significant role that predation on juveniles has in the natural selection of ungulates. Future research should compare characteristics, especially those known to influence survival, between animals killed by predators versus those killed by other sources as well as survivors versus non-survivors to better understand predation’s role in natural selection.

    Full Text Available The authors present results of researches whose aim was to determine the factors that may substantially influence population reproduction in the Republic of Serbia, taking into consideration all specific factors, like cultural background, economic situation, health education, health service organization, religious and historical factors, etc. The research was based on the population census from 1981. Seventeen regions of the inner part of the Republic of Serbia, Vojvodina and Kosovo were included in this research. Stratification was made according to the place of living (village, town age, occupation (farmer, housewife, non and half-qualified, qualified and highly qualified workers and education (without education, with unfinished or finished primary school, with secondary school, with college or university degree. In this way 2,141 women were questioned with 101 questions by the method of interview. Interviews were conducted exclusively by doctors - gynaecologists. We determined the frequency of the use of contraceptives, intentional abortions, spontaneous abortions, pre-term deliveries, marriage infertility and term deliveries. Thus, 57.4% of women had basic knowledge of contraception, but only 15.9% of them used it; 58.9% of women had intentional abortions; 16.2% of women had spontaneous abortions, 5.1% of them had pre-term deliveries, and 67% of women had term deliveries. Marriage infertility was found in 8.6% of women. When evaluating population health and behavior, we obtained some information and data concerning addicted diseases (alcohol, smoking, drugs, tranquilizers homosexuality and ways of sexual intercourse. It was concluded that enormous differences existed among certain regions in the Republic of Serbia, which were conditioned by the diversity of the above mentioned influences. Proposals for the measures to be undertaken in the Republic of Serbia in order to regulate population policy, are given.

  16. Factors influencing the stream-aquifer flow exchange coefficient.

    2014-01-01

    Knowledge of river gain from or loss to a hydraulically connected water table aquifer is crucial in issues of water rights and also when attempting to optimize conjunctive use of surface and ground waters. Typically in groundwater models this exchange flow is related to a difference in head between the river and some point in the aquifer, through a "coefficient." This coefficient has been defined differently as well as the location for the head in the aquifer. This paper proposes a new coefficient, analytically derived, and a specific location for the point where the aquifer head is used in the difference. The dimensionless part of the coefficient is referred to as the SAFE (stream-aquifer flow exchange) dimensionless conductance. The paper investigates the factors that influence the value of this new conductance. Among these factors are (1) the wetted perimeter of the cross-section, (2) the degree of penetration of the cross-section, and (3) the shape of the cross-section. The study shows that these factors just listed are indeed ordered in their respective level of importance. In addition the study verifies that the analytical correct value of the coefficient is matched by finite difference simulation only if the grid system is sufficiently fine. Thus the use of the analytical value of the coefficient is an accurate and efficient alternative to ad hoc estimates for the coefficient typically used in finite difference and finite element methods.

  17. Beyond the learning curve: factors influencing cost reductions in photovoltaics

    International Nuclear Information System (INIS)

    The extent and timing of cost-reducing improvements in low-carbon energy systems are important sources of uncertainty in future levels of greenhouse-gas emissions. Models that assess the costs of climate change mitigation policy, and energy policy in general, rely heavily on learning curves to include technology dynamics. Historically, no energy technology has changed more dramatically than photovoltaics (PV), the cost of which has declined by a factor of nearly 100 since the 1950s. Which changes were most important in accounting for the cost reductions that have occurred over the past three decades? Are these results consistent with the notion that learning from experience drove technical change? In this paper, empirical data are assembled to populate a simple model identifying the most important factors affecting the cost of PV. The results indicate that learning from experience, the theoretical mechanism used to explain learning curves, only weakly explains change in the most important factors-plant size, module efficiency, and the cost of silicon. Ways in which the consideration of a broader set of influences, such as technical barriers, industry structure, and characteristics of demand, might be used to inform energy technology policy are discussed

    Summary Red blood cell (RBC) alloimmunization may occur following transfusion or pregnancy/delivery. Although observational human studies have described the immunogenicity of RBC antigens and the clinical significance of RBC alloantibodies, studies of factors influencing RBC alloimmunization in humans are inherently limited by the large number of independent variables involved. This manuscript reviews data generated in murine models that utilize transgenic donor mice, which express RBC-specific model or authentic human blood group antigens. Transfusion of RBCs from such donors into nontransgenic but otherwise genetically identical recipient mice allows for the investigation of individual donor or recipient-specific variables that may impact RBC alloimmunization. Potential donor-related variables include methods of blood product collection, processing and storage, donor-specific characteristics, RBC antigen-specific factors, and others. Potential recipient-related variables include genetic factors (MHC/HLA type and polymorphisms of immunoregulatory genes), immune activation status, phenotype of regulatory immune cell subsets, immune cell functional characteristics, prior antigen exposures, and others. Although murine models are not perfect surrogates for human biology, these models generate phenomenological and mechanistic hypotheses of RBC alloimmunization and lay the groundwork for follow-up human studies. Long-term goals include improving transfusion safety and minimizing the morbidity/mortality associated with RBC alloimmunization. PMID:25670928

    Understanding the relationship between obesity and fast food consumption encompasses a broad range of individual level and environmental factors. One theoretical approach, the health capability framework, focuses on the complex set of conditions allowing individuals to be healthy. This qualitative study aimed to identify factors that influence individual level health agency with respect to healthy eating choices in uniformly constrained environments (e.g., fast food restaurants). We used an inductive qualitative research design to develop an interview guide, conduct open-ended interviews with a purposive sample of 14 student fast food workers (aged 18-25), and analyze the data. Data analysis was conducted iteratively during the study with multiple coders to identify themes. Emergent themes included environmental influences on eating behaviors (time, cost, restaurant policies, social networks) and internal psychological factors (feelings associated with hunger, food knowledge versus food preparation know-how, reaction to physical experiences, perceptions of food options, delayed gratification, and radical subjectivity). A localized, embedded approach to analyzing the factors driving the obesity epidemic is needed. Addressing contextual interactions between internal psychological and external environmental factors responds to social justice and public health concerns, and may yield more relevant and effective interventions for vulnerable communities.
