    2014-08-01

    In this study, the author developed a model to describe academic self-concept (ASC) in science and validated an instrument for its measurement. Unlike previous models of science ASC, which envisage science as a homogenous single global construct, this model took a multidimensional view by conceiving science self-concept as possessing distinctive facets including conceptual and procedural elements. In the first part of the study, data were collected from 1,483 students attending eight secondary schools in England, through the use of a newly devised Secondary Self-Concept Science Instrument, and structural equation modeling was employed to test and validate a model. In the second part of the study, the data were analysed within the new self-concept framework to examine learners' ASC profiles across the domains of science, with particular attention paid to age- and gender-related differences. The study found that the proposed science self-concept model exhibited robust measures of fit and construct validity, which were shown to be invariant across gender and age subgroups. The self-concept profiles were heterogeneous in nature with the component relating to self-concept in physics, being surprisingly positive in comparison to other aspects of science. This outcome is in stark contrast to data reported elsewhere and raises important issues about the nature of young learners' self-conceptions about science. The paper concludes with an analysis of the potential utility of the self-concept measurement instrument as a pedagogical device for science educators and learners of science.

  10. Hierarchical and Multidimensional Academic Self-Concept of Commercial Students.

    PubMed

    Yeung; Chui; Lau

    1999-10-01

    Adapting the Marsh (1990) Academic Self-Description Questionnaire (ASDQ), this study examined the academic self-concept of students in a school of commerce in Hong Kong (N = 212). Confirmatory factor analysis found that students clearly distinguished among self-concept constructs in English, Chinese, Math and Statistics, Economics, and Principles of Accounting, and each of these constructs was highly associated with a global Academic self-concept construct, reflecting the validity of each construct in measuring an academic component of self-concept. Domain-specific self-concepts were more highly related with students' intention of course selection in corresponding areas than in nonmatching areas, further supporting the multidimensionality of the students' academic self-concept. Students' self-concepts in the five curriculum domains can be represented by the global Academic self-concept, supporting the hierarchical structure of students' academic self-concept in an educational institution with a specific focus, such as commercial studies. The academic self-concepts of the commercial students are both multidimensional and hierarchical. Copyright 1999 Academic Press. PMID:10508533

    PubMed

    Isiksal, Mine

    2010-11-01

    The purpose of this study was to investigate Turkish and American undergraduate students' academic motivation and academic self-concept scores regarding the years that they spent in university. The analysis was based on 566 (284 Turkish, 282 American) undergraduate students where, Academic Motivation Scale and Academic Self-Concept Scale were used as measuring instruments. The results showed that there was a statistical significant effect of nationality and number of years spent in university on undergraduate students' intrinsic motivation, extrinsic motivation, and self-concept scores. Turkish students had higher intrinsic scores whereas American students had higher extrinsic scores and more positive academic-self concept compared to Turkish partners. Regarding grade level, senior students from both cultures had higher intrinsic motivation and academic self-concept scores compared to other grade levels. In terms of extrinsic motivation, there is steady decline in American students' scores as grade level increases. On the other hand, Turkish undergraduates' extrinsic scores decrease in the second year but increase in the third and fourth year of university education. Results were discussed by taking into consideration the social and cultural differences between two nations. PMID:20977008

    NASA Astrophysics Data System (ADS)

    Fathi-Ashtiani, Ali; Ejei, Javad; Khodapanahi, Mohammad-Karim; Tarkhorani, Hamid

    This study is surveying some of personality characteristics of adolescents and their associations with academic achievement: Accordingly, 1314 randomly allocated students of Tehran`s high schools were assessed by Beck self-concept inventory, Coopersmith self-esteem inventory, Spielberger State-Trait anxiety inventory, Beck depression inventory. Results indicate that self-concept is correlated with self-esteem and these two have positive impacts on augment of academic achievement. Moreover, the increase of self-concept and self-esteem are related to the decrease of anxiety and a negative significant relation exists between self-concept, self-esteem and depression which will ensue decrease in academic achievement.

  10. Academic self-concept of ability and cortisol reactivity.

    PubMed

    Minkley, N; Westerholt, D M; Kirchner, W H

    2014-05-01

    The present study aimed to clarify the relationship between a school-specific trait (academic self-concept of ability [ASCA]) and hormonal stress response by using a trait-compatible stressor (test). First, we determined 52 students' ASCA scores for biology and measured their salivary cortisol concentration before and after a biology test (experimental group, n=28) or a free writing task (control group, n=24). For participants who took the test, statistical analysis indicated a significant negative correlation between ASCA score and cortisol response. In contrast, the control group showed a decrease in cortisol concentrations between test times and no correlation between cortisol concentration and ASCA scores were found. These findings indicated an interaction between ASCA scores and hormonal stress response when an academic-related stressor is present. Furthermore, these variables might influence each other adversely: high cortisol concentrations during a test situation may lead to greater feelings of insecurity, resulting in low ASCA scores and awareness of these low scores may lead to a further increase in cortisol, creating a vicious cycle.

  19. Breaking the double-edged sword of effort/trying hard: Developmental equilibrium and longitudinal relations among effort, achievement, and academic self-concept.

    PubMed

    Marsh, Herbert W; Pekrun, Reinhard; Lichtenfeld, Stephanie; Guo, Jiesi; Arens, A Katrin; Murayama, Kou

    2016-08-01

    Ever since the classic research of Nicholls (1976) and others, effort has been recognized as a double-edged sword: while it might enhance achievement, it undermines academic self-concept (ASC). However, there has not been a thorough evaluation of the longitudinal reciprocal effects of effort, ASC, and achievement, in the context of modern self-concept theory and statistical methodology. Nor have there been developmental equilibrium tests of whether these effects are consistent across the potentially volatile early-to-middle adolescence. Hence, focusing on mathematics, we evaluate reciprocal effects models (REMs) over the first 4 years of secondary school (grades 5-8), relating effort, achievement (test scores and school grades), ASC, and ASC × Effort interactions for a representative sample of 3,144 German students (Mage = 11.75 years at Wave 1). ASC, effort, and achievement were positively correlated at each wave, and there was a clear pattern of positive reciprocal positive effects among ASC, test scores, and school grades-each contributing to the other, after controlling for the prior effects of all others. There was an asymmetrical pattern of effects for effort that is consistent with the double-edged sword premise: prior school grades had positive effects on subsequent effort, but prior effort had nonsignificant or negative effects on subsequent grades and ASC. However, on the basis of a synergistic application of new theory and methodology, we predicted and found a significant ASC × Effort interaction, such that prior effort had more positive effects on subsequent ASC and school grades when prior ASC was high-thus providing a key to breaking the double-edged sword.

    Arens, A. Katrin; Yeung, Alexander Seeshing; Craven, Rhonda G.; Hasselhorn, Marcus

    2011-01-01

    Academic self-concept is consistently proven to be multidimensional rather than unidimensional as it is domain specific in nature. However, each specific self-concept domain may be further separated into competence and affect components. This study examines the twofold multidimensionality of academic self-concept (i.e., its domain specificity and…

  15. The effect of high school chemistry instruction on students' academic self-concept

    NASA Astrophysics Data System (ADS)

    Morgan, Peter Wallace

    The purpose of this study was to investigate the effect of extended instruction in high school chemistry on the academic self-concept of students and determine what parts of the learning experience need to be addressed to make the interaction a more positive one. Fifty-seven students from three metropolitan public schools, who were enrolled in college preparatory chemistry classes, were asked to complete a written instrument, before and after extended chemistry instruction, that measures academic self-concept. Twenty-one of the students who took part in the written task volunteered to answer some in-depth interview questions concerning their academic self-concept and its relationship to chemistry instruction. Student responses, instrument scores, and student chemistry grades were analyzed for a variety of chemistry learning--academic self-concept connections and interactions. Results showed that there was a positive interaction for less than half of the students involved in the interview sessions. The results from the written instrument showed similar findings. Comparing chemistry grades and academic self-concept revealed an uncertain connection between the two, especially for students with strong academic self-concepts. Students felt that the laboratory experience was often disconnected from the remainder of chemistry instruction and recommended that the laboratory experience be integrated with classroom work. Students also expressed concerns regarding the volume of algorithmic mathematical calculations associated with college preparatory chemistry instruction. Results of this study suggest that secondary chemistry instruction must become more aware of the affective domain of learning and develop a mindful awareness of its connection to the cognitive domain if chemistry teaching and learning is going to better facilitate the intellectual growth of secondary students.

    1992-06-01

    Current research and theory have suggested that the relational domains of family and school experiences are important to children's development. The present study thus examined how relations with parents and school were related to Chinese students' psychosocial and cognitive development in self-concept, delinquency, and academic performance. A total of 1668 secondary school students were studied, and results showed that better relation with parents was associated with higher general, academic, appearance, social, and physical ability self-concepts. Better relation with school was associated with higher academic performance, as shown in higher class rank, higher grand total exam scores, and higher scores in Chinese, English, mathematics, physical education, and music. Both poorer relations with parents and school were found to associate with more self-reported delinquency as well as more school records of misconduct. PMID:1637685

    2015-01-01

    Academic self-concept could significantly affect academic achievement and self-confidence in children with epilepsy. However, limited attention has been devoted to determining factors influencing academic self-concept of children with epilepsy. We aimed to analyze potentially significant variables (gender, frequency of seizures, duration of epilepsy, intellectual disability, learning disability and attention deficit hyperactivity disorder) in relation to academic self-concept in children with epilepsy and to additional domains of their quality of life. The study group consisted of 182 children and adolescents aged 9-14 years who completed the SPAS (Student's Perception of Ability Scale) questionnaire determining their academic self-concept and the modified Czech version of the CHEQOL-25 (Health-Related Quality of Life Measure for Children with Epilepsy) questionnaire evaluating their health-related quality of life. Using regression analysis, we identified learning disability as a key predictor for academic-self concept of children with epilepsy. While children with epilepsy and with no learning disability exhibited results comparable to children without epilepsy, participants with epilepsy and some learning disability scored significantly lower in almost all domains of academic self-concept. We moreover found that children with epilepsy and learning disability have significantly lower quality of life in intrapersonal and interpersonal domains. In contrast to children with epilepsy and with no learning disability, these participants have practically no correlation between their quality of life and academic self-concept. Our findings suggest that considerable attention should be paid to children having both epilepsy and learning disability. It should comprise services of specialized counselors and teaching assistants with an appropriate knowledge of epilepsy and ability to empathize with these children as well as educational interventions focused on their teachers

    2014-01-01

    Research suggests that self-determination skills are positively correlated with factors that have been shown to improve academic achievement, but the direct relationship among self-determination, self-concept, and academic achievement is not fully understood. This study offers an empirical explanation of how self-determination and self-concept affect academic achievement for adolescents with learning disabilities after taking into consideration the covariates of gender, income, and urbanicity. In a nationally representative sample (N = 560), the proposed model closely fit the data, with all proposed path coefficients being statistically significant. The results indicated that there were significant correlations among the three latent variables (i.e., self-determination, self-concept, and academic achievement), with self-determination being a potential predictor of academic achievement for students with learning disabilities.

  20. Big Fish in a Big Pond: a study of academic self concept in first year medical students

    PubMed Central

    2011-01-01

    Background Big-fish-little-pond effect (BFLPE) research has demonstrated that students in high-ability environments have lower academic self-concepts than equally able students in low-ability settings. Research has shown low academic self-concepts to be associated with negative educational outcomes. Social comparison processes have been implicated as fundamental to the BFLPE. Methods Twenty first-year students in an Australian medical school completed a survey that included academic self-concept and social comparison measures, before and after their first written assessments. Focus groups were also conducted with a separate group of students to explore students' perceptions of competence, the medical school environment, and social comparison processes. Results The quantitative study did not reveal any changes in academic self-concept or self-evaluation. The qualitative study suggested that the attributions that students used when discussing performance were those that have been demonstrated to negatively affect self-concept. Students reported that the environment was slightly competitive and they used social comparison to evaluate their performance. Conclusions Although the BFLPE was not evident in the quantitative study, results from the qualitative study suggest that the BFLPE might be operating In that students were using attributions that are associated with lower self-concepts, the environment was slightly competitive, and social comparisons were used for evaluation.

    2016-01-01

    The present study investigated the developmental dynamics of general and subject-specific (i.e., mathematics, French, and German) components of students' academic self-concept, anxiety, and interest. To this end, the authors integrated three lines of research: (a) hierarchical and multidimensional approaches to the conceptualization of each construct, (b) longitudinal analyses of bottom-up and top-down developmental processes across hierarchical levels, and (c) developmental processes across subjects. The data stemmed from two longitudinal large-scale samples (N = 3498 and N = 3863) of students attending Grades 7 and 9 in Luxembourgish schools. Nested-factor models were applied to represent each construct at each grade level. The analyses demonstrated that several characteristics were shared across constructs. All constructs were multidimensional in nature with respect to the different subjects, showed a hierarchical organization with a general component at the apex of the hierarchy, and had a strong separation between the subject-specific components at both grade levels. Further, all constructs showed moderate differential stabilities at both the general (0.42 < r < 0.55) and subject-specific levels (0.45 < r < 0.73). Further, little evidence was found for top-down or bottom-up developmental processes. Rather, general and subject-specific components in Grade 9 proved to be primarily a function of the corresponding components in Grade 7. Finally, change in several subject-specific components could be explained by negative effects across subjects. PMID:27014162

  20. ASC Predictive Science Academic Alliance Program Verification and Validation Whitepaper

    SciTech Connect

    Klein, R; Graziani, F; Trucano, T

    2006-03-31

    The purpose of this whitepaper is to provide a framework for understanding the role that verification and validation (V&V) are expected to play in successful ASC Predictive Science Academic Alliance (PSAA) Centers and projects. V&V have been emphasized in the recent specification of the PSAA (NNSA, 2006): (1) The resulting simulation models lend themselves to practical verification and validation methodologies and strategies that should include the integrated use of experimental and/or observational data as a key part of model and sub-model validation, as well as demonstrations of numerical convergence and accuracy for code verification. (2) Verification, validation and prediction methodologies and results must be much more strongly emphasized as research topics and demonstrated via the proposed simulations. (3) It is mandatory that proposals address the following two topics: (a) Predictability in science & engineering; and (b) Verification & validation strategies for large-scale simulations, including quantification of uncertainty and numerical convergence. We especially call attention to the explicit coupling of computational predictability and V&V in the third bullet above. In this whitepaper we emphasize this coupling, and provide concentrated guidance for addressing item 2. The whitepaper has two main components. First, we provide a brief and high-level tutorial on V&V that emphasizes critical elements of the program. Second, we state a set of V&V-related requirements that successful PSAA proposals must address.

  4. The Academic Self-Concept of African American and Latina(o) Men and Women in STEM Majors

    NASA Astrophysics Data System (ADS)

    Espinosa, Lorelle L.

    If we are to respond to the call for equity in the representation of minority men and women in science, technology, engineering, and math (STEM) disciplines, we must be concerned with those college experiences that impact students' sense of self. This study addresses the 4-year development of academic self-concept for African American and Latina(o) students graduating with STEM degrees, with an emphasis placed on gender differences. Ordinary Least Squares regression was utilized to explore predictors of academic self-concept for male and female students. Findings emphasize the paramount role of the college environment as compared to background and precollege characteristics. Significant predictors exclusive to women include having positive academic self-expectations and valuing group work in a classroom setting. Significant predictors for men include being given the opportunity to work on a professor's research project and finding satisfaction with science and math coursework.

    Van Soom, Carolien; Donche, Vincent

    2014-01-01

    The low success rate of first-year college students in Science, Technology, Engineering, and Mathematics (STEM) programs has spurred many academic achievement studies in which explanatory factors are studied. In this study, we investigated from a person-oriented perspective whether different motivational and academic self-concept profiles could be discerned between male and female first-year college students in STEM and whether differences in early academic achievement were associated with these student groups. Data on autonomous motivation, academic self-concept, and early academic achievement of 1,400 first-year STEM college students were collected. Cluster analyses were used to distinguish motivational profiles based on the relative levels of autonomous motivation and academic self-concept for male and female students. Differences in early academic achievement of the various profiles were studied by means of ANCOVA. Four different motivational profiles were discerned based on the dimensions of autonomous motivation (A) and academic self-concept (S): students scoring high and respectively low on both dimensions (HA-HS or LA-LS), and students scoring high on one dimension and low on the other (HA-LS or LA-HS). Also gender differences were found in this study: male students with high levels of academic self-concept and autonomous motivation had higher academic achievement compared to male students with low levels on both motivational dimensions. For female students, motivational profiles were not associated with academic achievement. The findings partially confirm the internal and external validity of the motivational theories underpinning this study and extend the present insights on identifying subgroup(s) of at risk students in contemporary STEM programs at university level.

    2016-02-01

    Persistent academic achievement gaps exist between university students from high and low socioeconomic status (SES) backgrounds. The current research proposes that the extent to which a university is perceived as actively supporting versus passively neglecting students from diverse socioeconomic backgrounds can influence low-SES students' academic motivation and self-concepts. In Experiments 1 and 2, low-SES students exposed to cues suggestive of an institution's warmth toward socioeconomic diversity demonstrated greater academic efficacy, expectations, and implicit associations with high academic achievement compared with those exposed to cues indicating institutional chilliness. Exploring the phenomenology underlying these effects, Experiment 3 demonstrated that warmth cues led low-SES students to perceive their socioeconomic background as a better match with the rest of the student body and to perceive the university as more socioeconomically diverse than did chilliness cues. Contributions to our understanding of low-SES students' psychological experiences in academic settings and practical implications for academic institutions are discussed. PMID:26634272

    Green, Jasmine; Liem, Gregory Arief D; Martin, Andrew J; Colmar, Susan; Marsh, Herbert W; McInerney, Dennis

    2012-10-01

    The study tested three theoretically/conceptually hypothesized longitudinal models of academic processes leading to academic performance. Based on a longitudinal sample of 1866 high-school students across two consecutive years of high school (Time 1 and Time 2), the model with the most superior heuristic value demonstrated: (a) academic motivation and self-concept positively predicted attitudes toward school; (b) attitudes toward school positively predicted class participation and homework completion and negatively predicted absenteeism; and (c) class participation and homework completion positively predicted test performance whilst absenteeism negatively predicted test performance. Taken together, these findings provide support for the relevance of the self-system model and, particularly, the importance of examining the dynamic relationships amongst engagement factors of the model. The study highlights implications for educational and psychological theory, measurement, and intervention. PMID:22460236

  10. What Students Think They Feel Differs from What They Really Feel – Academic Self-Concept Moderates the Discrepancy between Students’ Trait and State Emotional Self-Reports

    PubMed Central

    Bieg, Madeleine; Goetz, Thomas; Lipnevich, Anastasiya A.

    2014-01-01

    This study investigated whether there is a discrepancy pertaining to trait and state academic emotions and whether self-concept of ability moderates this discrepancy. A total of 225 secondary school students from two different countries enrolled in grades 8 and 11 (German sample; n = 94) and grade 9 (Swiss sample; n = 131) participated. Students’ trait academic emotions of enjoyment, pride, anger, and anxiety in mathematics were assessed with a self-report questionnaire, whereas to assess their state academic emotions experience-sampling method was employed. The results revealed that students’ scores on the trait assessment of emotions were generally higher than their scores on the state assessment. Further, as expected, students’ academic self-concept in the domain of mathematics was shown to partly explain the discrepancy between scores on trait and state emotions. Our results indicate that there is a belief-driven discrepancy between what students think they feel (trait assessment) and what they really feel (state assessment). Implications with regard to the assessment of self-reported emotions in future studies and practical implications for the school context are discussed. PMID:24647760

    2010-01-01

    The study investigated Latina and European American adolescent girls’ (N = 345, M = 15.2 years, range = 13 to 18) experiences with academic sexism in mathematics and science (M/S) and their M/S perceived competence and M/S value (liking and importance). M/S academic sexism was based on girls’ reported experiences hearing sexist comments about girls’ abilities in math and science. Older European American adolescents, and both younger and older Latina adolescents, who experienced several instances of academic sexism felt less competent in M/S than girls who experienced less sexism (controlling for M/S grades). In addition, among older girls (regardless of ethnicity), those who experienced several instances of academic sexism valued M/S less than girls who experienced less sexism. PMID:21212810

    2016-01-01

    The relationship between self-concept and societal settings has been widely investigated in several Western and Asian countries, with respect to the academic self-concept in an educational environment. Although the musical self-concept is highly relevant to musical development and performance, there is a lack of research exploring how the musical self-concept evolves in different cultural settings and societies. In particular, there have been no enquiries yet in the Chinese music education environment. This study’s goal was the characterization of musical self-concept types among music students at a University in Beijing, China. The Musical Self-Concept Inquiry—including ability, emotional, physical, cognitive, and social facets—was used to assess the students’ musical self-concepts (N = 97). The data analysis led to three significantly distinct clusters and corresponding musical self-concept types. The types were especially distinct, in the students’ perception of their musical ambitions and abilities; their movement, rhythm and dancing affinity; and the spiritual and social aspects of music. The professional aims and perspectives, and the aspects of the students’ sociodemographic background also differed between the clusters. This study is one of the first research endeavors addressing musical self-concepts in China. The empirical identification of the self-concept types offers a basis for future research on the connections between education, the development of musical achievement, and the musical self-concept in societal settings with differing understandings of the self.

  17. Self-concept in children with attention deficits.

    PubMed

    Ljusberg, Anna-Lena; Brodin, Jane

    2007-09-01

    This study focuses on the BASTA project (basic skills, social interaction and training of the working memory), which studied children with attention deficits and hyperactive behaviour attending remedial classes in regular schools. The project is interdisciplinary, with research teams from both social science and medicine. Our study is both qualitative and quantitative with a socio-cultural approach, and focuses on the pupil's social interaction, self-concept and the classroom climate. This article reports on the results of the study on self-concept. Our supposition was that the pupil's self-concept should change when they improved their skills in reading, writing and mathematics, but this was not the case. The results showed the dominating pattern to be that the differences between data from the BASTA project and comparison data from a similar study on academic self-concept, social self-concept, personal self-concept and global self-concept are small to nonexistent. Our results indicate that the children studied report higher degrees of self-concept than were warranted and that entering remedial classes was often linked to previous academic failures, social failures or both.

    PubMed

    Rosenberg, B S; Gaier, E L

    1977-01-01

    The Coopersmith Self Esteem Inventory (CSEI) was administered to 23 Ss diagnosed to have learning disabilities, and normally achieving seventh graders (N = 70) to investigate: a) whether differences exist between the self-esteem of the adolescent with learning disabilities and the normally achieving adolescent, b) the dimensions of self concept in which these differences occur, and c) the relationship between self concept and the number of years in the special classroom for the adolescent with learning disabilities. The data were fitted to a 2 X 2 (ability X school) fixed effects non-orthogonal multivariate analysis of variance model. A significant difference (p less than .05) in "social self-peer" self concept favoring the "normally" achieving S's was found. A trend was evidenced for more negative "general self" and "school-academic" self concepts for the learning disabilities sample. Number of years in the special class did not appear associated with self concept as measured by the CSEI. PMID:596262

    Abstract Purpose To determine the self-concepts of chiropractic students as science students and if any personal variable affect their self-concepts. Participants Students in their first trimester and eighth trimester at the Los Angeles College of Chiropractic during the 1993 academic year (n=158). Methods Peterson-Yaakobi Q-Sort, National Assessment of Educational Progress, two-tailed T-test, one way analysis of variance and Spearman-rho correlation. Results The majority of students have positive self- concepts as science students and although there was a difference between the 2 trimesters, it was not significant. As a group they generally had less exposure to science compared to undergraduates from a selected science program. Variables of socio-economic status, undergraduate major, and highest completed level of education did not statistically affect their self-concept. Conclusion Chiropractic students had the self-concept that enables them to subscribe to the philosophical foundations of science and better engage in basic sciences and, later, science-based clinical research. Knowledge of this self- concept can be used in the development of a more rigorous basic science curricula and clinical research programs at chiropractic colleges with the ultimate goal of providing a more firm scientifically based foundation for the profession.

    PubMed

    Sharpes, D K; Wang, X

    1997-01-01

    Studies of self-concept have suffered from a lack of both a solid theoretical base and a clear definition of the term. It is not clear whether self-concept is a construct from the cognitive sciences, an active part of personality or of the ego and unconscious, or a physiological process as indicated from neurological research. Nor is it clear whether the psychological construct of self is related to other concepts, such as personal identity, self-esteem, and the ego, as sometimes these refer to the whole person or a structure or element within a person. What is evident is that the majority of researchers continue to assume that self-concept, however defined in theory, is primarily governed by environmental determinants despite abundant evidence from the neurosciences of the strong influence of its genetic heritability. This study assumed a genetic hypothesis, that self-concept is developmental and that adolescent perception of personal, relational, and academic self-identity occurs uniformly across cultures and environmental circumstances. Data were collected using a validated survey instrument, translated into Chinese, from majority and minority adolescents in the People's Republic of China. High similarity was found between the majority and minority adolescents, suggesting developmental propensities in the formation of self-concept. PMID:9426813

    2016-02-01

    When studying adolescent development, it is important to consider two key areas that are salient for teens, which are self-concept and peer relations. A secondary analysis of the National Institute of Health and Human Development Study of Early Child Care and Youth Development was conducted to examine the prospective bidirectional associations between self-concept and peer relations. To date, how social development broadly and peer relations in particular (e.g., relational aggression and victimization) affect self-concept domains is not fully understood. Using a large sample (N = 1063; 532 girls; M = 11.14 years; SD = .59) with multiple informants, the present study examined whether fifth grade relational aggression and sixth grade relational victimization was associated with adolescent self-concept in three key domains (i.e., academic, sports, physical appearance). A significant direct effect emerged, such that relational aggression in middle childhood was associated with decreases in academic self-concept and increases in sports self-concept in adolescence. Analyses also revealed that having higher levels of domain specific self-concept led to decreases in relational aggression across the transition to adolescence. The findings highlight the importance of examining bidirectional prospective associations between relational aggression, relational victimization, and domain specific self-concept. Implications for future research and clinical intervention are discussed. PMID:26419234

    Students' first-year academic success plays a critical role on their overall development in college, which implies the need to concentrate on identifying ways to improve students' first-year academic success. Different from most research on the subject, this study attempted to combine the sociological perspective of college impact with a psychological perspective to synthetically explore the causal relationship of specific types of self-concept and college involvement with academic success of medical students. A longitudinal study was conducted using 519 matriculates at a medical university in mainland China. We conducted the Cooperative Institutional Research Program freshmen survey and the Your First College Year survey to collect data of the pre-college and college academic and social self-concept, college involvement components, and some input characteristics. The academic success was measured by the first-year grade point average. A pathway analysis was conducted and showed the following results. Having high academic self-concept, being engaged in class and putting effort in homework or study directly contributes to increasing college achievement. Students' pre-college achievement and self-concept, faculty interaction, and homework involvement positively affected students' college academic self-concept development, which indirectly improved average grade point. These findings contribute to our understanding of a student's ability to interact with his or her collegiate environment and to experience academic success. PMID:24906461

    2009-01-01

    Objective To examine, in adolescents with mild to moderate malocclusion, the relationship between self-concept and demographic characteristics, a clinical assessment of malocclusion, self-perception of malocclusion, and self-perception of facial attractiveness. Methods and Materials Fifty-nine consecutive patients ages 9 to 15 years scheduled for initial records in a graduate orthodontic clinic consented to participate. Each subject independently completed the Multidimensional Self-Concept Scale (MSCS), the Facial Image Scale, and the Index of Treatment Need–Aesthetic Component (IOTN-AC). Peer Assessment Rating (PAR) scores were obtained from the patients’ diagnostic dental casts. Forward multiple-regression analysis with a backward overlook was used to analyze the effect of the demographic, clinical, and self-perception measures on each of the six self-concept (MSCS) domains. Results Self-perception of the dentofacial region was the only statistically significant predictor (P < .05) for the Global, Competence, Affect, Academic, and Physical domains of self-concept, while age, parental marital status, and the adolescent's self-perception of the dentofacial region were statistically significant predictors (P < .05) of Social Self-Concept. Conclusion The self-perceived level of the attractiveness or “positive” feelings toward the dentofacial region is more strongly related to self-concept than the severity of the malocclusion as indicated by the PAR score or by the adolescent's perception of their malocclusion.

    Molloy, Lauren E.; Ram, Nilam; Gest, Scott D.

    2014-01-01

    This study uses intraindividual variability and change methods to test theoretical accounts of self-concept and its change across time and context, and the developmental implications of this variability. The five-year longitudinal study of 541 youth in a rural Pennsylvania community from 3rd through 7th grade included twice-yearly assessments of self-concept (academic and social), corresponding external evaluations of competence (e.g., teacher-rated academic skills, peer-nominated “likeability”), and multiple measures of youths' overall adjustment. Multiphase growth models replicate previous research, suggesting significant decline in academic self-concept during middle school, but modest growth in social self-concept from 3rd through 7th grade. Next, a new contribution is made to the literature by quantifying the amount of within-person variability (i.e., “lability”) around these linear self-concept trajectories as a between-person characteristic. Self-concept lability was found to associate with a general profile of poorer competence and adjustment, and to predict poorer academic and social competence at the end of 7th grade above and beyond level of self-concept. Finally, there was substantial evidence that wave-to-wave changes in youths' self-concepts correspond to teacher and peer evaluations of youths' competence, that attention to peer feedback may be particularly strong during middle school, and that these relations may be moderated by between-person indicators of youths' general adjustment. Overall, findings highlight the utility of methods sensitive to within-person variation for clarifying the dynamics of youths' self-system development. PMID:21928883

  9. Effects of self-concept and perceived disapproval of delinquent behavior in school children.

    PubMed

    Leung, K; Lau, S

    1988-08-01

    It is argued that a multidimensional approach to self-concept may reveal intricate relations between self-concept and delinquent behavior, and that perceived approval of delinquent behaviors from referent groups may be related to the frequency of their occurrence. To evaluate these hypotheses, 1668 students from Grade 7 to Grade 9 responded to a questionnaire that measured their general self-esteem; their self-concept with regard to physical ability, social ability, physical appearance, and academic ability; the frequency they committed 15 delinquent acts; and the perceived approval of committing these acts from their parents, teachers, and friends. Regression analyses indicated that poor academic self-concept and poor relationship with school and parents were related to a higher frequency of delinquent behavior. However, a higher frequency of delinquent behavior was related to a more positive selfconcept with regard to social ability and physical ability. Finally, higher perceived approval from parents and peers was related to more delinquent behavior. Implications of these findings for identifying the antecedents and consequences of delinquent behavior were discussed. PMID:24271919

    In the type III secretion system (T3SS) of Aeromonas hydrophila, the putative needle complex subunit AscF requires both putative chaperones AscE and AscG for formation of a ternary complex to avoid premature assembly. Here we report the crystal structure of AscE at 2.7 Å resolution and the mapping of buried regions of AscE, AscG, and AscF in the AscEG and AscEFG complexes using limited protease digestion. The dimeric AscE is comprised of two helix–turn–helix monomers packed in an antiparallel fashion. The N-terminal 13 residues of AscE are buried only upon binding with AscG, but this region is found to be nonessential for the interaction. AscE functions as a monomer and can be coexpressed with AscG or with both AscG and AscF to form soluble complexes. The AscE binding region of AscG in the AscEG complex is identified to be within the N-terminal 61 residues of AscG. The exposed C-terminal substrate-binding region of AscG in the AscEG complex is induced to be buried only upon binding to AscF. However, the N-terminal 52 residues of AscF remain exposed even in the ternary AscEFG complex. On the other hand, the 35-residue C-terminal region of AscF in the complex is resistant to protease digestion in the AscEFG complex. Site-directed mutagenesis showed that two C-terminal hydrophobic residues, Ile83 and Leu84, of AscF are essential for chaperone binding. PMID:18662905

    1996-09-01

    We tested a theoretical model of individual differences in smoking cessation using a social-cognitive conception of the self-concept. We developed and validated measures of the smoker self-concept and the abstainer self-concept. Each scale was shown to have good internal reliability and construct validity and was distinct from other important predictive measures used in smoking research (e.g. Fagerstrom Tolerance Questionnaire, smoking rate, motivation, self-efficacy). Importantly, we demonstrated the predictive validity of the self-concept scales. The interaction of baseline measures of the smoker self-concept and abstainer self-concept predicted smoking status three months after treatment; subjects were most likely to be abstinent if they began treatment with a strong abstainer selfconcept and a weak smoker self-concept. This interaction held over and above baseline smoking rate, Fagerstrom Tolerance scores, and measures of motivation and self-efficacy to quit. The utility of social-cognitive individual difference models and potential patient-treatment matching interventions are discussed. PMID:24203766

    NASA Glenn Research Center (GRC) has been supporting development of the Advanced Stirling Radioisotope Generator (ASRG) since 2006. A key element of the ASRG project is providing life, reliability, and performance testing data of the Advanced Stirling Convertor (ASC). The latest version of the ASC (ASC-E3, to represent the third cycle of engineering model test hardware) is of a design identical to the forthcoming flight convertors. For this generation of hardware, a joint Sunpower and GRC effort was initiated to improve and standardize the test support hardware. After this effort was completed, the first pair of ASC-E3 units was produced by Sunpower and then delivered to GRC in December 2012. GRC has begun operation of these units. This process included performance verification, which examined the data from various tests to validate the convertor performance to the product specification. Other tests included detailed performance mapping that encompassed the wide range of operating conditions that will exist during a mission. These convertors were then transferred to Lockheed Martin for controller checkout testing. The results of this latest convertor performance verification activity are summarized here.

  18. Attitude Counts: Self-Concept and Success in General Chemistry

    NASA Astrophysics Data System (ADS)

    Lewis, Scott E.; Shaw, Janet L.; Heitz, Judith O.; Webster, Gail H.

    2009-06-01

    General chemistry is a required first step for students who wish to pursue a career in science or health professions. The course often has low rates of student success and as a result serves as a gateway limiting access to science fields. This study seeks to better understand factors that are related to student success in general chemistry by focusing on the affective domain, in this case students' self-concept, or self-evaluation of ability as it pertains to a specific field of study. First, a profile of students' self-concept in the general chemistry setting is created. Next, the relationship between self-concept and success in the course is investigated, including examining the role of self-concept after taking into account a cognitive measure (SAT scores). This study is unique in that evidence is found for the impact of self-concept after taking into account a cognitive measure. Finally, the effect of a semester-long, inquiry-oriented learning environment on students' self-concept is described. Suggested interventions to improve student self-concept are also discussed.

  1. Influence of Precollege Experience on Self-Concept among Community College Students in Science, Mathematics, and Engineering

    NASA Astrophysics Data System (ADS)

    Starobin, Soko S.; Laanan, Frankie Santos

    Female and minority students have historically been underrepresented in the field of science, mathematics, and engineering at colleges and universities. Although a plethora of research has focused on students enrolled in 4-year colleges or universities, limited research addresses the factors that influence gender differences in community college students in science, mathematics, and engineering. Using a target population of 1,599 aspirants in science, mathematics, and engineering majors in public community colleges, this study investigates the determinants of self-concept by examining a hypothetical structural model. The findings suggest that background characteristics, high school academic performance, and attitude toward science have unique contributions to the development of self-concept among female community college students. The results add to the literature by providing new theoretical constructs and the variables that predict students' self-concept.

    2015-01-01

    The Advanced Stirling Convertor (ASC) development effort was initiated by NASA Glenn Research Center (GRC) with contractor Sunpower Inc. to develop high efficiency thermal-to-electric power conversion technology for NASA Radioisotope Power Systems. Early successful performance demonstrations led to the expansion of the project as well as adoption of the technology by the Department of Energy (DOE) and system integration contractor Lockheed Martin Space Systems Company as part of the Advanced Stirling Radioisotope Generator (ASRG) flight project. The ASRG integrates a pair of ASCs to convert the heat from a pair of General Purpose Heat Source (GPHS) modules into electrical power. The expanded NASA ASC effort included development of several generations of ASC prototypes or Engineering Units to help prepare the ASC technology and Sunpower for flight implementation. Sunpower later had two parallel contracts allowing the last of the NASA Engineering Units called ASC-E3 to serve as pathfinders for the ASC-F flight convertors being built for DOE. The ASC-E3 convertors utilized the ASC-F flight specifications and were built using the ASC-F design and process documentation. Shortly after the first ASC-F Pair achieved initial operation, due to budget constraints, the DOE ASRG flight development contract was terminated. NASA continues to invest in the development of Stirling RPS technology including continued production of the ASC-E3 convertors, seven of which have been delivered with one additional unit in production. Starting in FY2015, Stirling Convertor Technology Maturation has been reorganized as an element of the RPS Stirling Cycle Technology Development (SCTD) Project and long-term plans for continued Stirling technology advancement are in reformulation. This paper provides a status on the ASC project, an overview of advancements made in the design and production of the ASC at Sunpower, and a summary of acceptance tests, reliability tests, and tactical tests at NASA

    2015-01-01

    Nurses are often faced with serious situations that require high levels of legal and ethical knowledge, and should therefore be sensitive to the moral issues in their profession in the decision making process. Some studies have investigated nurses' moral self-concept as an effective factor in moral sensitivity, but there is not sufficient evidence to support this. The purpose of this study was to determine the correlation between moral sensitivity and moral self-concept in nurses employed in the teaching hospitals in Zahedan, Iran. This cross-sectional descriptive study aimed to study the relationship between moral self-concept and moral sensitivity in nurses employed in the teaching hospitals affiliated with Zahedan University of Medical Sciences. Chang's Moral Self-Concept Questionnaire and Lutzen's Moral Sensitivity Questionnaire were used for data collection. Data analysis was performed using SPSS software version 17. A total of 188 nurses participated in this study. The results showed that there was a positive and significant relationship between moral self-concept and moral sensitivity (P < 0.05). Based on our findings, an individual's attention to moral issues can lead to greater sensitivity and result in morally responsible behavior at the time of decision making. Consequently, promotion of moral self-concept through personal effort or education can increase moral sensitivity, which in turn leads to behavioral manifestations of ethical knowledge.

    This study explores the self-concepts of Hong Kong Chinese with intellectual disabilities. Face-to-face and individual interviews were conducted in Cantonese, using the Chinese version of the Adult Source of Self-Esteem Inventory (ASSEI) together with three open-ended questions to explore the participants' self-conceptions in different life domains. An opportunity sample of 135 young adults with intellectual disabilities was interviewed. The findings showed that the family self, the social self and achievement in school and work were the self-concept attributes most important to the participants. The participants of this study had a higher total self-concept than that of a comparison group of people without disabilities when the participants used the in-group social comparison to maintain positive self-perception. The importance of partnership with family, self-concept enhancement strategies and quality employment service are discussed in order to facilitate people with intellectual disabilities to develop more positive self-concepts and thus achieve better community integration.

    Although everyone grows old, perception about the aging process and aging as measured physiologically vary widely. Perceptions of aging have psychologically influence on physical aging. This study was to examine the relationships between, self-concept, perception of aging, and physical aging in the elderly and to contribute to the theory development which may direct nursing intervention to promote well-being of the aged. Subjects were 70 women residents of a nursing home for the elderly in Seoul. Data collection was done from May 15 to June 15, 1988 using interview schedules and mechanical instruments. The instruments were selected items from the Health Self Concept Scale developed by Jacox and Stewart for self concept, and Secord and Jourad's Body Cathexis Scale and Osgood's Semantic Differential Scale for perception of aging. Physical aging was measured by mechanical instruments, inspection, questions, and palpation. The data were analysed for mean, t-test, ANOVA, and Pearson Correlation Coefficient using an S.P.S.S computerized program. The results of the analysis were as follows. 1. The mean level of self concept for the subject group was 16.97 (SD = +/- 6.17) in a range from 6-30. The mean level of perception of aging was 39.6. (SD = +/- 6.51) in a range from 13-65. The mean level of physical aging was 14.09 (SD = +/- 2.05) in a range from 8-40. 2. Relationships among self-concept, perception of aging, and physical aging. 1) There was a positive relationship between self-concept and perception of aging (r = 0.4461, p = 0.000). 2) There was a negative relationship between physical aging and perception of aging (r = -0.2975, p = 0.006). 3) There was a tendency toward a negative relationship between physical aging and self-concept, but not a significant relationship (r = -0.1033, p = 0.197). 3. 1) No general characteristic variables were related to self concept. 2) The general characteristic variable related to the level of perception of aging was religion (t = 4

    Background Dental malocclusions can be considered not only as an oral health problem, because they are linked to quality of life perception. Many factors related to malocclusion have strong influences on the perception of facial esthetics (eg, anterior tooth alignment, tooth shape and position, lip thickness, symmetric gingival or tooth contour, lip profile, and overjet). Many reports have shown that the perception of facial esthetics can influence psychological development from early childhood to adulthood. The aim of this study is to investigate the effect of dental malocclusion on self-esteem in a sample of adolescents. Materials and methods The study population was composed of 516 orthodontically untreated subjects (256 males) mean ages 13.75±1.977 years recruited from schools in the Campania region of Italy between January 2011 and July 2011. To evaluate the self-esteem grade in our population, all subjects filled out the Multidimensional Self Concept Scale questionnaire and attended an orthodontic clinical evaluation to estimate dental occlusal aspects. Results Pearson’s analysis shows the relationship in our sample between some occlusal characteristics (crossbite and dental crowding) and aspects of self-concept evaluation (social, competence, academic, physical, and global score) of the Multidimensional Self Concept Scale questionnaire. Moreover, logistic regression analysis shows the potential role of dental crowding (odds ratio 5.359; 95% confidence interval 3.492–8.225) and crossbite (odds ratio 6.153; 95% confidence interval 3.545–10.678) as risk factors for development of global self-concept score abnormalities. Conclusion Our findings confirm the relationship between psychosocial well-being, self-esteem, and dental malocclusion among adolescents. PMID:24672229

    The Advanced Stirling Convertor (ASC) was initially developed by Sunpower, Inc. under contract to NASA Glenn Research Center (GRC) as a technology development project. The ASC technology fulfills NASA s need for high efficiency power convertors for future Radioisotope Power Systems (RPS). Early successful technology demonstrations between 2003 to 2005 eventually led to the expansion of the project including the decision in 2006 to use the ASC technology on the Advanced Stirling Radioisotope Generator (ASRG). Sunpower has delivered 22 ASC convertors of progressively mature designs to date to GRC. Currently, Sunpower with support from GRC, Lockheed Martin Space System Company (LMSSC), and the Department of Energy (DOE) is developing the flight ASC-F in parallel with the ASC-E3 pathfinders. Sunpower will deliver four pairs of ASC-E3 convertors to GRC which will be used for extended operation reliability assessment, independent validation and verification testing, system interaction tests, and to support LMSSC controller verification. The ASC-E3 and -F convertors are being built to the same design and processing documentation and the same product specification. The initial two pairs of ASC-E3 are built before the flight units and will validate design and processing changes prior to implementation on the ASC-F flight convertors. This paper provides a summary on development of the ASC technology and the status of the ASC-E3 build and how they serve the vital pathfinder role ahead of the flight build for ASRG. The ASRG is part of two of the three candidate missions being considered for selection for the Discovery 12 mission.

    DIEHL, MANFRED; HAY, ELIZABETH L.

    2011-01-01

    This study focused on the identification of conceptually meaningful groups of individuals based on their joint self-concept differentiation (SCD) and self-concept clarity (SCC) scores. Notably, we examined whether membership in different SCD-SCC groups differed by age and also was associated with differences in psychological well-being (PWB). Cluster analysis revealed five distinct SCD-SCC groups: a self-assured, unencumbered, fragmented-only, confused-only, and fragmented and confused group. Individuals in the self-assured group had the highest mean scores for positive PWB and the lowest mean scores for negative PWB, whereas individuals in the fragmented and confused group showed the inverse pattern. Findings showed that it was psychologically advantageous to belong to the self-assured group at all ages. As hypothesized, older adults were more likely than young adults to be in the self-assured cluster, whereas young adults were more likely to be in the fragmented and confused cluster. Thus, consistent with extant theorizing, age was positively associated with psychologically adaptive self-concept profiles. This study examined whether conceptually meaningful subgroups of individuals can be identified based on their joint scores on self-concept differentiation (SCD) and self-concept clarity (SCC). Specifically, we considered whether individuals within such subgroups differed systematically from one another on measures of positive and negative psychological well-being (PWB). Of interest to us was also whether there were age differences in the distribution of adults across the SCD-SCC groups and whether age moderated the association between PWB and SCD-SCC grouping.

    2011-01-01

    Background The putative needle complex subunit AscF forms a ternary complex with the chaperones AscE and AscG in the type III secretion system of Aeromonas hydrophila so as to avoid premature assembly. Previously, we demonstrated that the C-terminal region of AscG (residues 62–116) in the hetero-molecular chaperone, AscE-AscG, is disordered and susceptible to limited protease digestion. Methodology/Principal Findings Here, we report the crystal structure of the ordered AscG1–61 region in complex with AscE at 2.4 Å resolution. Helices α2 and α3 of AscE in the AscE-AscG1–61 complex assumes a helix-turn-helix conformation in an anti-parallel fashion similar to that in apo AscE. However, in the presence of AscG, an additional N-terminal helix α1 in AscE (residues 4–12) is observed. PscG or YscG in the crystal structures of PscE-PscF-PscG or YscE-YscF-YscG, respectively, assumes a typical tetratricopeptide repeat (TPR) fold with three TPR repeats and one C-terminal capping helix. By comparison, AscG in AscE-AscG1–61 comprises three anti-parallel helices that resembles the N-terminal TPR repeats in the corresponding region of PscG or YscG in PscE-PscF-PscG or YscE-YscF-YscG. Thermal denaturation of AscE-AscG and AscE-AscG1–61 complexes demonstrates that the C-terminal disordered region does not contribute to the thermal stability of the overall complex. Conclusion/Significance The N-terminal region of the AscG in the AscE-AscG complex is ordered and assumes a structure similar to those in the corresponding regions of PscE-PscG-PscF or YscE-YscF-YscG complexes. While the C-terminal region of AscG in the AscE-AscG complex is disordered and will assume its structure only in the presence of the substrate AscF. We hypothesize that AscE act as a chaperone of the chaperone to keep AscG in a stable but partially disordered state for interaction with AscF. PMID:21559439

    1992-07-01

    Principal components analyses of the Beck Self-Concept Test (BST) were conducted independently for 288 women with primary mood disorders, 230 women with anxiety disorders, 236 men with mood disorders, and 161 men with anxiety disorders. Four self-concept dimensions that reflected (1) Intellectual Ability; (2) Work Efficacy; (3) Physical Attractiveness; and (4) Virtues/Vices occurred within the four samples. For 5-item subscales that represent these four dimensions, a two-way MANOVA found significant effects for sex and type of disorder. Women described themselves as having less intellectual ability than men did. Outpatients with mood disorders considered their physical appearance, work efficacy, and virtues/vices to be less acceptable than did those with anxiety disorders. Findings were discussed with respect to the cognitive content-specificity theory of psychopathology. PMID:1517436

    2012-12-01

    The current scientific evidence suggests that certain dimensions of the personality and self-concept act as risk factors of eating disorder (ED). However, there is little investigation that explores the different elements involved in both groups of variables together and in an exhaustive way. Our aim is to be able to discriminate between individuals diagnosed with ED and controls free of symptoms according to these personality traits and selfconcept. To accomplish our objective, the Inventory of Eating Disorders 2 (EDI-2), Inventory of Personality NEO Revised (NEO-PI-R) and Self-Concept Form-5 (AF-5) were administered to a sample composed of 69 cases of ED and 89 controls, and an analysis of logistic regression was carried out. The pattern obtained could correctly classify 96.2% of the people diagnosed with ED and, consistent with the previous research, it should work in the same way to detect people at risk of developing ED in the future.

    Angel, Elizabeth; Craven, Rhonda; Denson, Nida

    2012-08-01

    Professional self-concept is a critical driver of job satisfaction. In Australia, as international nursing enrolments rise, nursing is increasingly characterised by a professional body of international nurses who may differ from domestic Australian nurses in their nursing self-concept. At present, little is known about the extent to which domestic and international students nurses' self-concepts may differ. The present study aimed to elucidate and contrast domestic and international nursing students' self-concepts from one large Australian university. A total of 253 domestic (n=218) and international (n=35) undergraduate nursing students from a large public university in Sydney, Australia completed the Nurses' Self-Concept Instrument (NSCI). Multiple-Indicator-Multiple-Indicator-Cause (MIMIC) modelling was used to assess the effects of student group (domestic and international) on the latent self-concept factors of the NSCI. Domestic and international students' professional self-concepts were similarly high. MIMIC modelling demonstrated that domestic students had a higher patient care self-concept in comparison to international students. Results imply that it may be useful for Australian universities to foster strategies that enhance specific domains of self-concepts (e.g., care) which may be underdeveloped for at least some cultural groups within the international nursing student population compared with domestic nursing students.

    University students may encounter personal, family, social, and financial stresses while trying to cope with their academic challenges. Such constraints could affect their eating behavior and health status which, in turn may have negative effects on their studies. In light of little information in Malaysia on this subject, this study was undertaken on a sample of 180 students pursuing different academic programs in a Malaysian university. The study objectives were to determine the students' eating behavior including body weight control and the extent of fear of being fat, their social self concept that reflects the five selves namely, the psychological self, the social self, the sexual self, the family self and the physical self. Eating behavior and social self concept were determined based on various methods previously validated in studies on young adults in Asia and Australia. This article focuses on gender comparisons for these determinants. The results showed that psychological and emotional factors have a significant bearing on the eating behavior of university students. Uninhibited eating behavior of both the males and females showed significant and negative correlations with feelings pertaining to personal worth, the physical self, and their relationships with peers and families. Gender differences were manifested for some determinants. The females showed more restrained eating behavior than the males; the females have a significantly higher score for family relationship, which appears to be a significant factor on male students' eating behavior. Future studies on a larger sample size may help to unravel the extent to which psychological factors influence eating behavior of students, and the underlying psychosocial basis for some of the gender differences reported in this study.

    2014-08-01

    Self-concept is a critical indicator of quality of life but few studies have examined this subject in children with Down syndrome (DS). In this study, we propose a novel methodology to assess the self-concept of children with DS by analyzing their responses towards two dolls, one with a "typically developing" (TD) appearance and one with the phenotypic features of DS. Fifty-four children with DS participated in play sessions with both dolls and were then interviewed to assess doll preference, resemblance, and attribution of positive qualities. We observed that children with DS: (i) exhibited a preference for the TD doll regardless of age, gender, IQ or self-awareness; (ii) attributed more positive qualities to the TD doll than the DS doll; and (iii) believed that they resembled the TD doll, rather than the more phenotypically accurate representation of themselves. Older participants were more likely to exhibit self-recognition by this technique. These findings contribute to current understandings of how people with DS view themselves and their disability.

    Objective: Cognitive models suggest that the self-concept of persons with psychosis can be fundamentally affected. Self-concepts were found to be related to different symptom domains when measured concurrently. Longitudinal investigations to disentangle the possible causal associations are rare. Method: We examined a sample of 160 people with a diagnosis of schizophrenia who took part in a psychotherapy study. All participants had the DSM-IV diagnosis of a schizophrenia and pronounced negative symptoms. Neurocognition, symptoms, and self-concepts were assessed at two time points 12 months apart. Structural equation modeling was used to test whether symptoms influence self-concepts (scar-model) or self-concepts affect symptoms (vulnerability model). Results: Negative symptoms correlated concurrently with self-concepts. Neurocognitive deficits are associated with more negative self-concepts 12 months later. Interpersonal self-concepts were found to be relevant for paranoia. Conclusion: The findings implicate that if deficits in neurocognition are present, fostering a positive self-concept should be an issue in therapy. Negative interpersonal self-concept indicates an increased risk for paranoid delusions in the course of 1 year. New aspects for cognitive models in schizophrenia and clinical implications are discussed. PMID:26191025

The questionnaires included detailed information on participation in leisure activities, background characteristics, reasons for parachuting, and self-concept; answers were obtained from an overwhelmingly middle-class, White, male, young, and college educated sample. The findings (based on descriptive statistics, correlations, and regression analysis) did not support our expectations regarding birth order and participation in dangerous sports. Several were even in opposite direction to our expectations. We did find some support for our expectation that self-efficacy would be positively related to participation in dangerous sports, but not for our expectation that self-efficacy would be related to birth order. We concluded that birth order continues to be a frustrating variable in studies of socialization. PMID:8336297

    Graduate nurse attrition is an increasing phenomenon within a world of decreasing nursing numbers. The newly developed nursing self-concept of the graduate nurse may provide a key indicator for predicting graduate retention. This study explores the development of multiple dimensions of nursing self-concept and examines their relationship to graduate nurse retention plans. A descriptive survey design with repeated measures was utilised to assess nurse self-concept and retention plans. The key findings suggest that multiple dimensions of graduate nurse self-concepts rise significantly in the second half of their graduate year and that nurse general self-concept is a strong predictor of graduate nurse retention. The implications of this study are that monitoring of self-concept throughout the transitional period for new nurses can lead to early detection and appropriate intervention strategies thereby improving retention rates for new nurses.

    The objectives of this research are: (a) analyze the incremental validity of physical activity's (PA) influence on perceived quality of life (PQL); (b) determine if PA's predictive power is mediated by self-concept; and (c) study if results vary according to a unidimensional or multidimensional approach to self-concept measurement. The sample comprised 160 women from Burgos, Spain aged 18 to 45 years old. Non-probability sampling was used. Two three-step hierarchical regression analyses were applied to forecast PQL. The hedonic quality-of-life indicators, self-concept, self-esteem, and PA were included as independent variables. The first regression analysis included global self-concept as predictor variable, while the second included its five dimensions. Two mediation analyses were conducted to see if PA's ability to predict PQL was mediated by global and physical self-concept. Results from the first regression shows that self-concept, satisfaction with life, and PA were significant predictors. PA slightly but significantly increased explained variance in PQL (2.1%). In the second regression, substituting global self-concept with its five constituent factors, only the physical dimension and satisfaction with life predicted PQL, while PA ceased to be a significant predictor. Mediation analysis revealed that only physical self-concept mediates the relationship between PA and PQL (z = 1.97, p < .050), and not global self-concept. Physical self-concept was the strongest predictor and approximately 32.45 % of PA's effect on PQL was mediated by it. This study's findings support a multidimensional view of self-concept, and represent a more accurate image of the relationship between PQL, PA, and self-concept. PMID:26898406

  5. Advanced Stirling Convertor (ASC-E2) Performance Testing at NASA Glenn Research Center

    The National Aeronautics and Space Administration (NASA) Glenn Research Center (GRC) has been supporting development of the Advanced Stirling Radioisotope Generator (ASRG) since 2006. A key element of the ASRG Project is providing life, reliability, and performance testing of the Advanced Stirling Convertor (ASC). For this purpose, four pairs of ASCs capable of operating to 850 C and designated with the model number ASC-E2, were delivered by Sunpower of Athens, OH, to GRC in 2010. The ASC-E2s underwent a series of tests that included workmanship vibration testing, performance mapping, and extended operation. Workmanship vibration testing was performed following fabrication of each convertor to verify proper hardware build. Performance mapping consisted of operating each convertor at various conditions representing the range expected during a mission. Included were conditions representing beginning-of-mission (BOM), end-of-mission (EOM), and fueling. This same series of tests was performed by Sunpower prior to ASC-E2 delivery. The data generated during the GRC test were compared to performance before delivery. Extended operation consisted of a 500-hour period of operation with conditions maintained at the BOM point. This was performed to demonstrate steady convertor performance following performance mapping. Following this initial 500-hour period, the ASC-E2s will continue extended operation, controller development and special durability testing, during which the goal is to accumulate tens of thousands of hours of operation. Data collected during extended operation will support reliability analysis. Performance data from these tests is summarized in this paper.

  7. Thine Own Self: True Self-Concept Accessibility and Meaning in Life

    2016-01-01

    A number of philosophical and psychological theories suggest the true self is an important contributor to well-being. The present research examined whether the cognitive accessibility of the true self-concept would predict the experience of meaning in life. To ensure that any observed effects were due to the true self-concept rather than the self-concept more generally, we utilized actual self-concept accessibility as a control variable in all studies. True and actual self-concepts were defined as including those traits which are enacted around close others versus most others (Studies 1 through 3) or as traits that refer to “who you really are” vs. “who you are during most of your activities” (Studies 4 and 5), respectively. Studies 1 and 2 showed that individual differences in true self-concept accessibility, but not differences in actual self-concept accessibility, predicted meaning in life. Study 3 showed that priming traits related to the true self led to enhanced meaning in life. Studies 4 and 5 provided correlational and experimental support for the role of true self-concept accessibility in meaning in life, even when traits were defined without reference to social relationships and when state self-esteem and self-reported authenticity were controlled. Implications for the study of the true self-concept and authenticity are discussed. PMID:19159144

    Microbes or danger signals trigger inflammasome sensors, which induce polymerization of the adapter ASC and assembly of an ASC speck. ASC specks recruit and activate caspase-1, which induces IL-1β cytokine maturation and pyroptotic cell death. Here we show that after pyroptosis ASC specks accumulate in the extracellular space, where they promote further IL-1β maturation. In addition, phagocytosis of ASC specks induces lysosomal damage, nucleation of soluble ASC as well as caspase-1 and IL-1β activation in the recipient cell. ASC specks appear in bodily fluids from inflamed tissues and autoantibodies against ASC specks develop in patients and animals with autoimmune pathologies. Together, these findings reveal extracellular functions of ASC specks and a novel form of cell-to-cell communication. PMID:24952505

    Meggs, Jennifer; Ditzfeld, Christopher; Golby, Jim

    2014-01-01

    The present study examines the relationship between individual differences in evaluative self-organisation and mental toughness in sport, proposing that motivation and emotional resiliency (facets of mental toughness) stem from differences in core self. A cross-sectional assessment of 105 athletes competing at a range of performance levels took part in an online study including measures of self-reported mental toughness (Sport Mental Toughness Questionnaire; Sheard, M., Golby, J., & van Wersch, A. (2009). Progress towards construct validation of the Sports Mental Toughness Questionnaire (SMTQ). European Journal of Psychological Assessment, 25(3), 186-193. doi:10.1027/1015-5759.25.3.186) and self-organisation (self-descriptive attribute task; Showers, C. J. (2002). Integration and compartmentalisation: A model of self-structure and self-change. In D. Cervone & W. Mischel (Eds.), Advances in personality science (pp. 271-291). New York, NY: Guilford Press). As predicted, global mental toughness was associated with self-concept positivity, which was particularly high in individuals with positive-integrative self-organisation (individuals who distribute positive and negative self-attributes evenly across multiple selves). Specifically, positive integration was associated with constancy (commitment to goal achievement despite obstacles and the potential for failure), which extends presumably from positive integratives' emotional stability and drive to resolve negative self-beliefs.

    Wong, Wayne A.; Wilson, Scott; Collins, Josh

    2014-01-01

    Sunpower's Advanced Stirling Convertor (ASC) initiated development under contract to the NASA Glenn Research Center (GRC) and after a series of successful demonstrations, the ASC began transitioning from a technology development project to flight development project. The ASC has very high power conversion efficiency making it attractive for future Radioisotope Power Systems (RPS) in order to make best use of the low plutonium-238 fuel inventory in the U.S. In recent years, the ASC became part of the NASA-Department of Energy Advanced Stirling Radioisotope Generator (ASRG) Integrated Project. Sunpower held two parallel contracts to produce ASC convertors, one with the Department of Energy/Lockheed Martin to produce the ASC-F flight convertors, and one with NASA GRC for the production of ASC-E3 engineering units, the initial units of which served as production pathfinders. The integrated ASC technical team successfully overcame various technical challenges that led to the completion and delivery of the first two pairs of flight-like ASC-E3 by 2013. However, in late Fall 2013, the DOE initiated termination of the Lockheed Martin ASRG flight development contract driven primarily by budget constraints. NASA continues to recognize the importance of high efficiency ASC power conversion for RPS and continues investment in the technology including the continuation of ASC-E3 production at Sunpower and the assembly of the ASRG Engineering Unit #2. This paper provides a summary of ASC technical accomplishments, overview of tests at GRC, plans for continued ASC production at Sunpower, and status of Stirling technology development.

    Background and aims. Different factors affect children’s behavior during dental treatment, including psychological and behavioral characteristics. The aim of this study was to evaluate the correlation of self-concept on child’s anxiety and behavior during dental treatment in 4 to 6-year-old children. Materials and methods. A total of 235 preschoolers aged 4 to 6 years were included in this descriptive analytic study. Total self-concept score for each child was assessed according to Primary Self-concept Scale before dental treatment. Child’s anxiety and child’s behavior were assessed, during the restoration of mandibular primary molar, using clinical anxiety rating scale and Frankl Scale, respectively. Spearman’s correlation coefficient was used to evaluate the correlation between the total self-concept score with the results of clinical anxiety rating scale and Frankl Scale. Results. There was a moderate inverse correlation between the self-concept and clinical anxiety rating scale scores (r = -0.545, P < 0.001), and a moderate correlation between the self-concept and child’s behavior scores (r = 0.491, P < 0.001). A strong inverse relation was also found between the anxiety and behavior scores (r = -0.91, P < 0.001). Conclusion. Children with higher self-concept had lower anxiety level and better behavioral feedback during dental treatment. PMID:26697152

    1989-01-01

    To examine drinking problems and self concept of college students raised in homes where alcohol is abused, 148 lower division college students were given the following paper and pencil tests: The Michigan Alcoholism Screening Test, The Children of Alcoholics Screening Test, and the "Personal Self" section of The Tennessee Self Concept Scale. Students classified as children of alcoholics had a significantly lower self concept (F = 4.23, p = .04). Tabulation of the incidence of heavy drinking (31%) and lapses of memory after drinking bouts (62%) show an amount of drinking on college campuses that is truly alarming. PMID:2728960

    The present study examines the association between the self-concept and adaptation to conjugal loss; the primary aim was to explore whether those individuals high in self-esteem, environmental mastery, and optimism have more adaptive resources with which to ameliorate the detrimental sequelae of bereavement. Analyses were conducted on data collected from 58 widows every four months over a two-year period. One goal of the research was to explore the adequacy of the theoretically chosen operational definition of the self-concept; another goal was to analyze how changes in the level of self-concept components correlated with changes in levels of depression, health, and grief resolution as individuals adjusted to their losses. Analyses revealed that trajectories of depression and grief resolution were more highly related than health to changes in self-concept. PMID:17152410

Several measures of global self-esteem and multidimensional self-concept were administered to 61 boys and 64 girls. Analysis showed that boys reported higher scores than girls on global self-esteem, measured on the Coopersmith Self-esteem Inventory and the Feelings of Inadequacy Scale by Janis-Field, but this result was not reproduced when self-esteem was measured on the Rosenberg Self-esteem Scale. No differences have been found in domain-specific self-concepts, except for the ethical-moral self-concept, on which girls reported higher scores than boys. PMID:11191376

    School improvement programs are often assessed in terms of their effect on school climate and education outcomes. The School Development Program (SDP) of the Yale Child Study Center has been shown to have a positive influence on those two factors. We also recognize the importance of positively influencing students' affective, intra-personal, and motivational states, such as their self-evaluations. The present study examined the effects of the SDP on multiple dimensions of students' self-concepts. The Piers Harris Self-Concept Scale was administered to 174 fourth and sixth graders, half of whom attended SDP schools and half control schools. Significant positive changes in self-concept were observed among the SDP students but not among the control students. Program students also showed significantly higher self-concepts on post-test measures when compared to normative samples. PMID:2275218

    Developing a sexual self-concept is an important developmental task of adolescence; however, little empirical evidence describes this development, nor how these changes are related to development in sexual behavior. Using longitudinal cohort data from adolescent women, we invoked latent growth curve analysis to: (1) examine reciprocal development in sexual self-concept (sexual openness, sexual esteem and sexual anxiety) over a four year time frame; (2) describe the relationship of these trajectories with changes in sexual behavior. We found significant transactional effects between these dimensions and behavior: sexual self-concept evolved during adolescence in a manner consistent with less reserve, less anxiety and greater personal comfort with sexuality and sexual behavior. Moreover, we found that sexual self-concept results from sexual behavior, as well as regulates future behavior. PMID:20970178

    2008-01-01

    This study assessed the relationship between girls’ weight status and self-concept and examined peer teasing and parent criticism as potential mediators of this relationship. Data were collected for 182 girls and their parents when the girls were 5 and 7 years old. At each age, girls’ body mass index, self-concept, peer weight-related teasing (child report), and parents’ criticism of girls’ weight status (spouse report) were assessed. At ages 5 and 7, girls who were more overweight reported lower self-concept. Peer teasing and parent criticism mediated the relationship between weight status and self-concept at age 7, but not at age 5. In addition, the duration and timing of parent criticism across ages 5 and 7 mediated the association between girls’ weight status at age 5 and perceived peer acceptance at age 7. PMID:12220051

    OBJECTIVES: The primary objective of the present study was to assess self-concept in adolescents with type 1 diabetes, and to determine whether this is associated with attitudes toward having chronic disease, family functioning or severity of diabetes. The secondary objective was to assess the impact of family income, sex, age and age at diagnosis on adolescent self-concept. METHODS: A cross-sectional, self-report survey of 48 adolescents with type 1 diabetes (22 boys and 26 girls; mean ± SD age at time of study 15.2±1.7 years [range 12.2 to 18.0 years]; mean age at diagnosis 9.2±3.3 years [range 1.3 to 14.9 years]) was performed using the Piers-Harris Children’s Self-Concept (PHCSC) scale, second edition; the Child Attitude Toward Illness Scale; and the Family Assessment Measure scale, version III. Demographic information including net family income and a symptom inventory form to assess disease severity was collected. RESULTS: Adolescents’ self-concept measured by the PHCSC scale was significantly positively correlated with a more positive attitude toward chronic illness as measured by the Child Attitude Toward Illness Scale. The PHCSC scale was found to have a significant negative correlation with the Family Assessment Measure scale score, indicating that a better self-concept was correlated with enhanced family functioning. Self-concept was not significantly correlated with disease severity, income of family, sex, age at diagnosis, age at time of study, episodes of diabetic ketoacidosis or episodes of hypoglycemia. CONCLUSIONS: Adolescents with better self-concept had more positive attitudes toward their chronic illness and enhanced family functioning. Although no correlation with diabetes disease severity was seen in the study population, interventions aimed at improving adolescent self-concept may have a positive impact on diabetes treatment by improving attitude toward living with type 1 diabetes.

    Childhood trauma (CT) and psychosis may be associated. Drawing on the dissociation and social psychological literature, the current study examined the mediating role of structural aspects of self in explaining the relationship between childhood trauma and psychosis. Twenty-nine individuals with psychosis were compared with 31 healthy volunteers regarding childhood trauma, dissociation and self-concept clarity (SCC). High rates of maltreatment were found in the psychosis sample. Additionally, clinical participants reported more dissociation and less self-concept clarity. Mediational analyses were carried out on pooled data from across both clinical and non-clinical samples. These suggested that the influence of physical neglect in increasing the likelihood of experiencing psychosis was explicable through the effects of increased dissociation. Self-concept clarity mediated the relationship between psychosis and total childhood trauma, emotional abuse, physical abuse, emotional and physical neglect. Furthermore, dissociation and self-concept clarity were strongly correlated providing evidence that they may form a unitary underlying concept of 'self-concept integration'. The study provides further evidence of the link between childhood trauma and psychosis. Self-concept integration may be adversely affected by negative childhood experiences, which increases psychosis risk. Methodological limitations, clinical implications and suggestions for future research are considered. PMID:26099655

    Apoptosis-associated speck-like protein containing a caspase recruitment domain (ASC) is silenced by promoter methylation in many types of tumors, yet ASC's role in most cancers remains unknown. Here, we show that ASC is highly expressed in a model of medulloblastoma, the most common malignant pediatric brain cancer; ASC is also expressed in human medulloblastomas. Importantly, while ASC deficiency did not affect normal cerebellar development, ASC knockout mice on the Smoothened (ND2:SmoA1) transgenic model of medulloblastoma exhibited a profound reduction in medulloblastoma incidence and a delayed tumor onset. A similar decrease in tumorigenesis with ASC deficiency was also seen in the hGFAP-Cre:SmoM2 mouse model of medulloblastoma. Interestingly, hyperproliferation of the external granule layer (EGL) was comparable at P20 in both wild-type and ASC-deficient SmoA1 mice. However, while the apoptosis and differentiation markers remained unchanged at this age, proliferation makers were decreased, and the EGL was reduced in thickness and area by P60. This reduction in proliferation with ASC deficiency was also seen in isolated SmoA1 cerebellar granule precursor cells in vitro, indicating that the effect of ASC deletion on proliferation was cell autonomous. Interestingly, ASC-deficient SmoA1 cerebella exhibited disrupted expression of genes in the transforming growth factor-β pathway and increased level of nuclear Smad3. Taken together, these results demonstrate an unexpected role for ASC in Sonic hedgehog-driven medulloblastoma tumorigenesis, thus identifying ASC as a promising novel target for antitumor therapy.

    Free-piston Stirling convertors are fundamental to the development of NASA s next generation of radioisotope power system, the Advanced Stirling Radioisotope Generator (ASRG). The ASRG will use General Purpose Heat Source (GPHS) modules as the energy source and Advanced Stirling Convertors (ASCs) to convert heat into electrical energy, and is being developed by Lockheed Martin under contract to the Department of Energy. Achieving flight status mandates that the ASCs satisfy design as well as flight requirements to ensure reliable operation during launch. To meet these launch requirements, GRC performed a series of quasi-static mechanical tests simulating the pressure, thermal, and external loading conditions that will be experienced by an ASC-E2 heater head assembly. These mechanical tests were collectively referred to as "lateral load tests" since a primary external load lateral to the heater head longitudinal axis was applied in combination with the other loading conditions. The heater head was subjected to the operational pressure, axial mounting force, thermal conditions, and axial and lateral launch vehicle acceleration loadings. To permit reliable prediction of the heater head s structural performance, GRC completed Finite Element Analysis (FEA) computer modeling for the stress, strain, and deformation that will result during launch. The heater head lateral load test directly supported evaluation of the analysis and validation of the design to meet launch requirements. This paper provides an overview of each element within the test and presents assessment of the modeling as well as experimental results of this task.

    The Advanced Stirling Convertor (ASC) is being developed by an integrated team of Sunpower and National Aeronautics and Space Administration s (NASA s) Glenn Research Center (GRC). The ASC development, funded by NASA s Science Mission Directorate, started as a technology development effort in 2003 and has since evolved through progressive convertor builds and successful testing to demonstrate high conversion efficiency, low mass, and capability to meet long-life Radioisotope Power System (RPS) requirements. The technology has been adopted by the Department of Energy and Lockheed Martin Space Systems Company s Advanced Stirling Radioisotope Generator (ASRG), which has been selected for potential flight demonstration on Discovery 12. This paper provides an overview of the status of ASC development including the most recent ASC-E2 convertors that have been delivered to GRC and an introduction to the ASC-E3 and ASC flight convertors that Sunpower will build next. The paper also describes the technology maturation and support tasks being conducted at GRC to support ASC and ASRG development in the areas of convertor and generator extended operation, high-temperature materials, heater head life assessment, organics, nondestructive inspection, spring fatigue testing, and other reliability verification tasks.

    The ``Radioastron'' space mission is the unique project of Russian Space Agency (Roscosmos) and Russian Academy of Sciences to investigate the Universe by means of implementation of VLBI principles with 'Spectr-R' space vehicle. The 10-m radiotelescop onboard ``Spectr-R'' is fully operational since 15 November, 2011 as the Space element of Ground-to-Space interferometer at the orbit with the apogee up to 350000 km. The correlator for Radioastron mission is a part of a ASL (Astro Space Locator) computer complex for Windows environment fully developed at Astro Space Center (ASC) of Lebedev Physical Institute. In the report the main features and operational procedures of the ASC correlator are described with the emphasis on the differences in data-processing from the ground VLBI. The description is given of the algorithm of time delay and its derivatives calculations that is a question of principle for a correlation procedure of the ground-space interferometer data. Methods of extracting of the correlation results are analyzed in terms of efficiency and parameterization of the correlator operations. Some scientific results of a number of observing sessions are given as illustrations.

    For the FY15 ASC L2 Trilab Codesign milestone Sandia National Laboratories performed two main studies. The first study investigated three topics (performance, cross-platform portability and programmer productivity) when using OpenMP directives and the RAJA and Kokkos programming models available from LLNL and SNL respectively. The focus of this first study was the LULESH mini-application developed and maintained by LLNL. In the coming sections of the report the reader will find performance comparisons (and a demonstration of portability) for a variety of mini-application implementations produced during this study with varying levels of optimization. Of note is that the implementations utilized including optimizations across a number of programming models to help ensure claims that Kokkos can provide native-class application performance are valid. The second study performed during FY15 is a performance assessment of the MiniAero mini-application developed by Sandia. This mini-application was developed by the SIERRA Thermal-Fluid team at Sandia for the purposes of learning the Kokkos programming model and so is available in only a single implementation. For this report we studied its performance and scaling on a number of machines with the intent of providing insight into potential performance issues that may be experienced when similar algorithms are deployed on the forthcoming Trinity ASC ATS platform.

    In recent years, modeling and simulation has played an increasingly important role in the maintenance of the nuclear stockpile. The Advanced Simulation and Computing (ASC) program continues to support and encourage the development of a modeling and simulation infrastructure to make these goals a reality. The Distance Computing Network has been making make the ASC resources available to users throughout the tri-lab environment for over five years. This network relies on the Transmission Control Protocol/Internet Protocol (TCP/IP) protocol suite to provide high performance and reliable communications. Understanding TCP/IP operation in this unique environment is critical. Software modeling has been used to analyze current network performance and predict the effect of proposed changes. Recently the network architecture was radically changed and the software model had to be changed as well. Whereas the original network was based on 2.5 gigabit per second ATM links, the redesigned network is comprised of 10-gigabit Ethernet links arranged as a 3-node ring. Therefore, a new software model was needed to continue to predict the performance of proposed changes and allow engineers to experiment with new network applications without the risk of interfering with critical operations.

    This study explores self-concept among indigenous young people from different ecocultural niches in Chiapas (Mexico) through a particular self-concept task. Previous theory and research has described 3 cultural models linked with specific sociodemographic settings that foster particular psychologies. Our aim was to compare the results of the self-concept test among indigenous groups from different sociodemographic settings in order to observed possible differences. We predicted that individuals from rural communities with little formal education (hypothesised to be Interdependent) would have self-concepts with more social and less personal components than would those with an urban, highly educated (hypothesised to be Independent), and we expected a third group of highly educated young people living in an urban context but with a rural background (hypothesised to be autonomous-related group) to value social and personal components equally. The results supported this hypothesis. Based on ecocultural theory, it is suggested that sociodemographic contexts affect the self-concept. PMID:25354051

    Many social-cognitive models of psychotic-like symptoms posit a role for self-concept and aberrant salience. Previous work has shown that the interaction between aberrant salience and self-concept clarity is associated with self-reported psychotic-like experiences. In the current research with two structured interviews, the interaction between aberrant salience and self-concept clarity was found to be associated withinterview-rated psychotic-like experiences. The interaction was associated withpsychotic-like experiences composite scores, delusional ideation, grandiosity, and perceptual anomalies. In all cases, self-concept clarity was negatively associated with psychotic-like experiences at high levels of aberrant salience, but unassociated with psychotic-like experiences at low levels of aberrant salience. The interaction was specific to positive psychotic-like experiences and not present for negative or disorganized ratings. The interaction was not mediated by self-esteem levels. These results provide further evidence that aberrant salience and self-concept clarity play an important role in the generation of psychotic-like experiences. PMID:25102085

    The present study investigated the self-concept of deaf and hard-of-hearing (DHH) students in different educational settings compared with those of hearing students in Ethiopia. The research involved a sample of 103 Grade 4 students selected from 7 towns in Ethiopia. They were selected from a special school for the deaf, a special class for the deaf, and a regular school. The Self-Description Questionnaire I (Marsh, 1990) was used to measure the children's self-concept. The study results indicated that, in comparison with their hearing peers, DHH students had a lower self-concept in the areas of general self, general school, reading, and parental relations. The DHH students in the special school showed a higher self-concept in regard to their physical appearance than the hearing and DHH students in the special class. There were no statistically significant differences between the groups in the self-concept dimensions of peer relations, mathematics, and physical abilities. PMID:27338275

    The purpose of the present study was to determine the effect of composition (art or music) on the self-concept of hospitalized children. The music composition was created using the program Making More Music. The art composition was a drawing using standard medium. The Piers-Harris Children's Self-Concept Scale was used to measure self-concept. When examining subjects as one group, a significant difference from pre- to posttest for the Total score indicated an improved self-concept. Further analyses on each of the 6 categories indicated no significant differences. The art composition group had a significant difference from pre- to posttest for the Total score and for Popularity (POP). Although not significant, scores increased from pre- to posttest for Behavioral Adjustment (BEH), Physical Appearance (PHY), Freedom from Anxiety (FRE), and Happiness and Satisfaction (HAP). The music composition group had no significant difference from pre- to posttest for the Total score but a significant difference from pre- to posttest on Intellectual and School Status (INT) and Physical Appearance (PRY). Although not significant, scores increased from pre- to posttest for TOT, BEH, and HAP. There was a significant difference between the groups on 2 categories that indicated an improved self-concept for the music group under Intellectual and School Status and for the art group under Popularity.

    Myeloid cells assemble inflammasomes in response to infection or cell damage; cytosolic sensors activate pro-caspase-1, indirectly for the most part, via the adaptors ASC and NLRC4. This leads to secretion of proinflammatory cytokines and pyroptosis. To explore complex formation under physiological conditions, we generated an alpaca single domain antibody, VHHASC, which specifically recognizes the CARD of human ASC via its type II interface. VHHASC not only impairs ASC(CARD) interactions in vitro, but also inhibits inflammasome activation in response to NLRP3, AIM2, and NAIP triggers when expressed in living cells, highlighting a role of ASC in all three types of inflammasomes. VHHASC leaves the Pyrin domain of ASC functional and stabilizes a filamentous intermediate of inflammasome activation. Incorporation of VHHASC-EGFP into these structures allowed the visualization of endogenous ASC(PYD) filaments for the first time. These data revealed that cross-linking of ASC(PYD) filaments via ASC(CARD) mediates the assembly of ASC foci. PMID:27069117

    The TIMSS 1995, 1999, and 2003 data have been gathered from Hong Kong before and after its sovereignty switch from the United Kingdom to China in 1997. Built on a reciprocal relation theory from the research literature, this investigation is designed to examine models of student self-concept and mathematics achievement during the political transition. Along with a perceived `brain drain' from the population migration, there was a non-monotonic change in the reciprocal relationship between self-concept and mathematics achievement. In addition, indicators of mathematics achievement and self-concept have demonstrated different linkages to the permanent emigration of Hong Kong residents with valued or desirable skills and qualifications. Interpretation of these empirical findings entails a need of enhancing cross-cultural understanding in mathematics education.

    The inflammasomes are multiprotein complexes that activate caspase-1 in response to infections and stress, resulting in the secretion of pro-inflammatory cytokines. Here we report that IκB kinase α (IKKα) is a critical negative regulator of apoptosis-associated specklike protein containing a C-terminal caspase-activation-andrecruitment (CARD) domain (ASC)-dependent inflammasomes. IKKα controls the inflammasome at the level of the adaptor ASC, which interacts with IKKα in the nucleus of resting macrophages in an IKKα kinase-dependent manner. Loss of IKKα kinase activity results in inflammasome hyperactivation. Mechanistically, the downstream nuclear effector IKK-related kinase (IKKi) facilitates translocation of ASC from the nucleus to the perinuclear area during inflammasome activation. ASC remains under the control of IKKα in the perinuclear area following translocation of the ASC/IKKα complex. Signal 2 of NLRP3 activation leads to inhibition of IKKα kinase activity through the recruitment of PP2A, allowing ASC to participate in NLRP3 inflammasome assembly. Taken together, these findings reveal a IKKi-IKKα-ASC axis that serves as a common regulatory mechanism for ASC-dependent inflammasomes. PMID:25266676

    In this study we examined the link between the parent-adolescent relationship and the adolescent's relationship with peers. The proposed model assumes that the quality of the parent-child relationship affects the adolescent's self-concept, which in turn affects the adolescent's integration into the world of peers. The sample consisted of 508 families with adolescents (12- to 18-years-old). The data were obtained at the subjects' homes, where a battery of questionnaires was administered individually to mothers, fathers and adolescents. Several constructs relating to the quality of parent-child relationship were assessed: parental acceptance, attachment, involvement, responsiveness, love withdrawal and monitoring of the child. The measures of the adolescent's self-concept included Harter's Perceived Competence Scale for Adolescents and Rosenberg's Self-Esteem Scale. The indicators of the quality of peer relations were: degree of peer activity, having a best friend, perceived acceptance by peers and attachment to peers. Assessment of the hypothesized model showed that the adolescent's self-concept serves a mediating role in the relationship between maternal child-rearing style and involvement with peers. The mediating role of self-concept was greatest for maternal acceptance. Paternal child-rearing style, however, appeared to have an independent effect on the adolescent's involvement with peers that is not accounted for by the adolescent's self-concept. The prediction of the quality of adolescents' peer relations yielded similar results for both mothers and fathers. The results suggest that a positive self-concept and warm supportive parenting each contribute unique variance to satisfactory peer relations. PMID:9104652

    The purpose of this study was to determine to what extent female physical fitness and self-concept are affected by dance team participation in high school. Eight dancers were tested once prior to and once four months after dance team participation. Eight participants from physical education classes, matched for age, weight, height, grade, and race, were tested once at the same time as the second dance team test. Physiological tests were maximum oxygen uptake, sit-and-reach, one-repetition maximum bench press, skinfolds, and hydrostatic weighing. The self-concept tests were Coopersmith Self-Esteem Inventory, Tennessee Self-Concept Scale, and Body Cathexis Scale. Dependent one-tailed t tests were run to determine differences between dance team pre- and posttests and control and dance team posttests. Dance subjects increased maximum oxygen uptake and one-repetition maximum bench press in addition to improving their body composition as evidenced by a significant decrease in total skinfolds and a near significant decrease in percent body fat. The dance team had a significantly higher maximum oxygen uptake than did controls. No other significant differences were seen between groups. Dance team participants significantly improved physical self and social self on the Tennessee Self-Concept Scale. No other significant differences were seen. A factor that may have affected the self-concept results in this study was low dance team status, due to a combination of unsuccessful previous dance teams and a losing football season. Within the limitations of this study, these results indicate that physical fitness is improved as a result of dance team participation; however, self-concept seems to be affected only minimally, if at all, as compared with participation in physical education classes.

    Purpose The purpose of this study was to assess the impact of a cognitive behavioral therapy (CBT) anxiety intervention on social phobia, social skill development, and self-concept. Method Fifteen children with epilepsy and a primary anxiety disorder participated in a CBT intervention for 12 weeks plus a 3-month follow-up visit. Children were assessed at baseline, week 7, week 12, and 3 months post treatment to measure changes in social phobia using the Screen for Child Anxiety Related Emotional Disorders (SCARED). Self-concept was also assessed by using the Piers-Harris Children's Self-Concept Scale II (Piers-Harris 2). Results There was a significant reduction in symptoms of social phobia and improved self-concept at the end of the 12-week intervention and at the 3 month follow-up. Repeated measures ANOVA's of child ratings revealed significant change over time on the SCARED-Social Phobia/Social Anxiety subscale score (p = 0.024). In terms of self-concept, significant change over time was detected on the Piers-Harris 2-Total score (p = 0.015) and several subscale scores of Piers-Harris 2, including: Physical Appearance and Attributes (p = 0.016), Freedom from Anxiety (p = 0.005), and Popularity (p = 0.003). Conclusion This pilot investigation utilized an evidenced based CBT intervention to reduce symptoms of social phobia, which in turn provided a vehicle to address specific social skills improving self-concept in children with epilepsy.

    Background: People with visual disability have lower self-esteem and social skills than sighted people. This study was designed to describe self-esteem and general and sexual self-concepts in blind people. Materials and Methods: This was a cross-sectional study, conducted in the Isfahan University of Medical Sciences in 2013-2014. In this study, 138 visually impaired people participated from Isfahan Province Welfare Organization and were interviewed for measuring of self-esteem and self-concept using Eysenck self-esteem and Rogers’ self-concept questionnaires. The correlation between above two variables was measured using Statistical Package for the Social Sciences (SPSS) software by Pearson correlation test. Results: Mean [± standard deviation (SD)] age of patients was 30.9 ± 8 years. The mean (±SD) of general self-concept score was 11 ± 5.83. The mean (±SD) of self-esteem score was 16.62 ± 2.85. Pearson correlation results showed a significant positive correlation between self-esteem and general self-concept (r = 0.19, P = 0.025). The mean of sexual self-concept scores in five subscales (sexual anxiety, sexual self-efficacy, sexual self-esteem, sexual fear, and sexual depression) were correspondingly 11 ± 4.41, 19.53 ± 4.53, 12.96 ± 4.19, 13.48 ± 1.76, and 5.38 ± 2.36. Self-esteem and self-concept had significant positive correlation with sexual anxiety (r = 0.49; P < 0.001) (r = –.23; P < 0.001) and sexual fear (r = 0.25; P = 0.003) (r = 0.18; P = 0.02) and negative correlation with sexual self-efficacy (r = –0.26; P = 0.002) (r = –0.28; P = 0.001) and sexual-esteem (r = –0.34; P < 0.001) (r = –0.34; P < 0.001). Conclusion: Self-esteem and self-concept had significant correlation with sexual anxiety and sexual fear; and negative correlation with sexual self-efficacy and sexual-esteem. PMID:26929756

    In the present study, 123 college students were surveyed in order to assess their self-concepts, evaluations of parents, and perceptions of their parents' parenting styles. Notably, the students' self-concepts were found to vary directly with perceived level of parental warmth, but did not vary as a function of their parents' level of restrictiveness. Fathers and mothers were found to be rated more highly if they were perceived as being warm and permissive rather than hostile and restrictive. Finally, opposite-sex parents' level of warmth also correlated with how each parent was evaluated. Some explanations for these findings are offered. PMID:1471569

  5. Test Hardware Design for Flightlike Operation of Advanced Stirling Convertors (ASC-E3)

    Oriti, Salvatore M.

    2012-01-01

    NASA Glenn Research Center (GRC) has been supporting development of the Advanced Stirling Radioisotope Generator (ASRG) since 2006. A key element of the ASRG project is providing life, reliability, and performance testing of the Advanced Stirling Convertor (ASC). For this purpose, the Thermal Energy Conversion branch at GRC has been conducting extended operation of a multitude of free-piston Stirling convertors. The goal of this effort is to generate long-term performance data (tens of thousands of hours) simultaneously on multiple units to build a life and reliability database. The test hardware for operation of these convertors was designed to permit in-air investigative testing, such as performance mapping over a range of environmental conditions. With this, there was no requirement to accurately emulate the flight hardware. For the upcoming ASC-E3 units, the decision has been made to assemble the convertors into a flight-like configuration. This means the convertors will be arranged in the dual-opposed configuration in a housing that represents the fit, form, and thermal function of the ASRG. The goal of this effort is to enable system level tests that could not be performed with the traditional test hardware at GRC. This offers the opportunity to perform these system-level tests much earlier in the ASRG flight development, as they would normally not be performed until fabrication of the qualification unit. This paper discusses the requirements, process, and results of this flight-like hardware design activity.

    Free-piston Stirling convertors are fundamental to the development of NASA s next generation of radioisotope power system, the Advanced Stirling Radioisotope Generator (ASRG). The ASRG will use General Purpose Heat Source (GPHS) modules as the energy source and Advanced Stirling Convertors (ASCs) to convert heat into electrical energy, and is being developed by Lockheed Martin under contract to the Department of Energy. Achieving flight status mandates that the ASCs satisfy design as well as flight requirements to ensure reliable operation during launch. To meet these launch requirements, GRC performed a series of quasi-static mechanical tests simulating the pressure, thermal, and external loading conditions that will be experienced by an ASC E2 heater head assembly. These mechanical tests were collectively referred to as lateral load tests since a primary external load lateral to the heater head longitudinal axis was applied in combination with the other loading conditions. The heater head was subjected to the operational pressure, axial mounting force, thermal conditions, and axial and lateral launch vehicle acceleration loadings. To permit reliable prediction of the heater head s structural performance, GRC completed Finite Element Analysis (FEA) computer modeling for the stress, strain, and deformation that will result during launch. The heater head lateral load test directly supported evaluation of the analysis and validation of the design to meet launch requirements. This paper provides an overview of each element within the test and presents assessment of the modeling as well as experimental results of this task.

    PubMed

    Montpetit, Mignon A; Bergeman, C S; Bisconti, Toni L

    2010-08-01

    The self-concept is often considered to be a personal resource that individuals may use to cope with life stressors, but little is known about how this entity might itself change in response to profound stress. The present study examines structural change in self-concept following conjugal loss in later life. Analyses were conducted on data collected from 57 widows every 4 months over the first 2 years post-loss. The first objective was to explore the adequacy of an operational definition of the self-concept as a latent construct lying at the confluence of self-esteem, perceived environmental mastery, and optimism. Because confirmatory factor analysis (CFA) supported this theoretically based conceptualization, the second objective of the study was to model stability and change in the structure of the self-concept over the 2-year study period. Results suggested that there is both stability and change in the self-system during the adjustment to major life stress. PMID:21197123

  4. Who am I? The relationship between self-concept uncertainty and materialism.

    PubMed

    Noguti, Valeria; Bokeyar, Alexandra L

    2014-10-01

    It is well accepted that materialism may result in a number of negative consequences, hence the importance of improving its understanding. In this paper, we propose that materialism negatively relates to self-concept uncertainty. Uncertainty about oneself is aversive and those feeling uncertain may use the possession of material objects as a way to reduce the uncertainty. Inasmuch as material objects can serve as concrete signs of self-worth, self-concept uncertainty can therefore relate to more materialism. Over two studies, one in Australia and the other in the US, with a total of 390 participants, our research demonstrates that lower clarity about one's self-concept associates with higher levels of materialism. While this result holds for both genders, this relationship is considerably stronger for women compared to men. We also find that lower self-concept clarity relates to higher compulsive buying. We further demonstrate that materialism relates to higher positive moods during shopping, and also relates to higher negative moods after shopping, more notably negative moods towards what was purchased. This effect is significant even when controlling for general affective states. PMID:25178953
