    Full Text Available The present study aimed to identify the exercise motives according to selected socio-demographic indicators in university students. The sample was comprised of 2,380 individuals (1,213 men and 1,167 women aged between 18 and 35 years. The exercise motives were identified with the Portuguese-translated version of the Exercise Motivations Inventory (EMI-2. University students gave significantly greater importance to exercise for reasons identified as Disease Prevention. Factors that are less relevant in statistical language were identified in a context of motivation associated with Social Recognition and Competition. Sex, age, family economic class, experience with exercise and body weight had a significant effect on the level of importance of exercise among university students. In conclusion, the results found can contribute to the development of physical activity promotion programs and a possible reduction in the number of dropouts among university students.

    2007-07-01

    The purpose of this study was to qualitatively explore clinical instructors' (CIs) perceptions of students' behaviors that comprise entry-level clinical performance, as well as how those perceptions were integrated into their decision making. The participants were 21 physical therapists who were CIs for physical therapist students. Using a grounded theory approach, we conducted interviews, asking the question, "What is it about students' performance that makes you see them as entry-level therapists?" We determined common themes among the interviews and developed a schema to explain the decision-making process. Participants identified 7 attributes that, when demonstrated to a sufficient degree, illustrated to them students' ability to practice at the entry level. Those attributes were knowledge, clinical skills, safety, clinical decision making, self-directed learning, interpersonal communication, and professional demeanor. Participants viewed these attributes in concert to form a subjective "gut feeling" that a student demonstrated entry-level performance. A final theme emerged suggesting a definition of entry-level performance as "mentored independence." Participants reported evaluating students' performance based on attributes similar to those suggested by the American Physical Therapy Association's Physical Therapist Clinical Performance Instrument and previous research. However, subjectivity also was involved in their decision about whether students were able to practice at the entry level. Participants also concluded that entry-level students need not be independent in all clinical situations.

    There is little information on the current mental health of University students in Uganda. The present study was carried out to determine the prevalence of depressed mood and suicidal ideation among students at Makerere University. Two student samples participated. Sample I comprised 253 fresh students admitted to all faculties at the University in the academic year 2000/2001, selected by a simple random sampling procedure. Sample II comprised 101 students admitted to the Faculty of Medicine during the academic year 2002/2003. The prevalence of depressed mood was measured using the 13-item Beck Depression Inventory (BDI). The prevalence of depressed mood (BDI score 10 or more) was significantly higher in sample I (16.2%) than sample II (4.0%). Sample I members were significantly more likely than those of sample II to report lifetime and past week suicide ideation. Thus, there is a high prevalence of mental health problems among the general population of new students entering Makerere University and this is significantly higher than for new students in the Faculty of Medicine.

    2004-10-01

    This study assessed Internet use and attitudes toward illicit use of the Internet in a sample of Russian college students. A sample comprised of 198 students was recruited from a university in Moscow. Each participant completed a survey assessing demographic characteristics, Internet use, and attitudes towards engaging in illicit behaviors over the Internet. About half of the students reported that they used the Internet at least several times a year, with 8% reporting daily use of the Internet. Among Internet users, most reported having Internet access either at home or at a friends' home, and 16 % reported having Internet access from work, school, or a computer center. Among Internet users, the main purpose was for school-related activities (60%), followed by e-mail (55%), entertainment (50%), chatting (24%), and searching for pornography (6%). Although most students thought it was inappropriate to read someone else's e-mail, use someone else's password or credit card information without their permission, or break into someone's computer, many students did endorse those illicit behaviors. Over a fifth of the students reported that they knew hackers. Forty three percent of students agreed that people make too much fuss about watching videos, movies or downloading music on the Internet without paying. Males were more likely than females to report using the Internet for entertainment purposes (p = 0.006) and were more likely to agree that it was okay to break into someone's computer (p = 0.04). The results of this study suggest that these Russian college students predominately use the Internet to help with their schoolwork, to communicate with others, and for entertainment. These results also suggest that interventions may be useful to change attitudes endorsing illicit uses of the Internet.

    2010-01-01

    In this qualitative study, we explored how students understood "culture." Participants defined culture and wrote narratives regarding specific cultural encounters. The sample comprised both nursing (n=14) and non-nursing (n=8) students to allow for comparison groups. Content analysis of the narratives revealed two broad paradigms of cultural understanding: essentialist and constructivist. Essentialist narratives comprised four themes: determinism (culture defied individual resistance); relativism (the possibility of making value judgments disappeared); Othering (culture was equated to exotica, and emphasized difference); and, reductionism (personhood was eclipsed by culture). In contrast, the constructivist narratives were characterized by influence (non-determinism), dynamism (culture was dynamic and evolutionary); and, relationship-building. The unintended negative consequences of essentialist notions of culture were revealed in the nursing students' narratives. Pedagogy is implicated in nursing students' essentialized understanding of culture.

    Full Text Available Marija Spasenoska,1 Shane Costello,1 Brett Williams2 1Faculty of Education, 2Department of Community Emergency Health and Paramedic Practice, Monash University, Melbourne, VIC, Australia Objective: The purpose of this present study was to investigate the psychometric properties of the Jefferson Scale of Physician Empathy – student version (JSPE-S. Subjects and methods: This study recruited 193 Malaysian medical students enrolled in year one and year two studies. A principal-component analysis with Varimax rotation was conducted. Procrustes rotation was used to confirm the item to model fit, which allows for a comparison of actual structure against an ideal hypothesized structure. Items were systematically removed based on low communalities of < 0.3 and poor loading of items onto components. Results: A two-component solution was found, comprised of “perspective taking” and “compassionate care”. Following item removal, eleven items remained. A Procrustes analysis revealed that this eleven-item measure demonstrated an excellent model fit. A possible third component was identified, though is not recommended for use, due to construct underrepresentation. Conclusion: This study found the Jefferson Scale of Physician Empathy fitted best to a two-component model using eleven items. Item, component, and overall congruence were very high, and scale reliabilities were adequate. The results of this study suggest that the eleven-item, two-component solution demonstrates excellent psychometric properties and structural validity in a Malaysian medical student population. Future research could consider using the short eleven-item measure in both student and health care profession samples to investigate the role of empathy in health care.

Individual differences in sensation seeking (SS), as measured by the Sensation Seeking Scale Form (SSS-V), have been found to be predictive of PG among university student samples. However, what is less clear, is if the four SSS-V subscales capture unique facets of SS that are particularly predictive of PG. Much less studied than SS, competitiveness has also been found to be predictive of PG. The Competitiveness Orientation Measure (COM) is a newly developed measure of competitiveness, comprising of four facets. The main purpose of the current study was to examine if these four facets of competitiveness predicted variance in PG over and above the variance predicted by the four SSS-V subscales. Participants included 158 university student gamblers. Sequential regression analysis showed that after accounting for gender, age, and the four SSS-V subscales the only facet of the COM found to be a significant predictor of PG severity was Dominant Competitiveness. Dominant Competitiveness predicted an additional 11% of PG severity. These results provide support for the Dominant Competitiveness subscale of the COM as having utility in predicting PG over and above the predictive utility of the SSS-V subscales. Practical implications for the current findings are discussed.

    To identify prevalence and predictors of participation in the online drinking game 'neknomination' amongst university students. A convenience sample of 145 university students participated in a study about drinking behaviours, completing a questionnaire about their participation in neknomination, the Alcohol Use Disorders Identification Test, and the Resistance to Peer Influence Scale. Out of 145 students sampled, 54% took part in neknomination in the previous month. Mann-Whitney U tests revealed significantly higher scores on the Alcohol Use Disorders Identification Test, and significantly lower scores on the Resistance to Peer Influence Scale, for those who had participated in neknomination. A significant correlation was also shown between specific peer pressure to neknominate, and engagement in neknomination. A logistic regression analysis indicated that scores on the Alcohol Use Disorders Identification Test, but not the Resistance to Peer Influence Scale, predicted classification as an individual who participated in neknomination. We found that over half of respondents had participated in a neknomination game in the past month, with almost all male respondents having done so. Participation in neknomination was strongly associated with general hazardous drinking behaviour but not with resistance to peer influence. Further research is needed to understand the role of engagement with social media in drinking games and risky drinking.

    1999-06-01

    A related paper (Summerfield & Youngman, 1999) has described the development of a scale, the Student Self-Perception Scale (SSPS) designed to explore the relationship between academic self-concept, attainment and personality in sixth form college students. The study aimed to identify groups of students exhibiting varying patterns of relationship using a range of measures including the SSPS. Issues of gender and also examined. The samples comprised a pilot sample of 152 students (aged 16-17 years from two sixth form colleges) and a main sample of 364 students (mean age, 16 yrs 10 mths range 16:0 to 18:6 years, from one sixth form college). The main sample included similar numbers of male and female students (46% male, 54% female) and ethnic minority students comprised 14% of this sample. Data comprised responses to two personality measures (the SSPS, Summerfield, 1995, and the Nowicki-Strickland Locus of Control Scale, Nowicki & Strickland, 1973), various student and tutor estimates of success, and performance data from college records. Students were classified using relocation cluster analysis and cluster differences verified using discriminant function analysis. Thirty outcome models were tested using covariance regression analysis. Eight distinct and interpretable groups, consistent with other research, were identified but the hypothesis of a positive, linear relationship between mastery and academic attainment was not sustained without qualification. Previous attainment was the major determinant of final performance. Gender variations were detected on the personality measures, particularly Confidence of outcomes, Prediction discrepancy, Passivity, Mastery, Dependency and Locus of control, and these were implicated in the cluster characteristics. The results suggest that a non-linear methodology may be required to isolate relationships between self-concept, personality and attainment, especially where gender effects may exist.

    2018-05-15

    Most drinking game (DG) research among university students has been conducted among USA college samples. The extent to which demographics and game type (e.g. team and sculling games) are linked to DG behaviours/consequences among non-USA students is not well understood. As such, the current study investigated characteristics of DG participation (and associated outcomes) among a sample of Australian university students. University students (N = 252; aged 18-24 years; 67% female) who had consumed alcohol in the prior year completed an online survey. Measures included demographics, DG behaviours (lifetime, frequency and consumption) and gaming-specific consequences. Most of the students reported lifetime DG participation (85%). Among those who played a DG in the prior 6 months (69%), most had experienced a negative gaming-specific consequence. While team games were the most popular DG played, regression analysis demonstrated that participation in games which encouraged consumption (e.g. sculling) were associated with increased alcohol consumption during play. In addition to being older, playing DGs more frequently, and consuming more alcohol while playing, participation in both consumption and dice games (e.g. 7-11, doubles) predicted more negative gaming-specific consequences. DG participation is common among Australian university students, as it is in other parts of the world. The importance of game type is clear, particularly the risk of consumption games. Findings could help inform interventions to reduce participation in consumption games and identify students who might be especially at-risk for experiencing negative DG consequences. © 2018 Australasian Professional Society on Alcohol and other Drugs.

  18. The Social Acceptance of Secondary School Students with Learning Disabilities (LD

    Directory of Open Access Journals (Sweden)

    Teja Lorger

    2015-06-01

    Full Text Available This paper aims to shed light on the level of social acceptance among students with learning disabilities (LD in various secondary school vocational programs in comparison with their peers without disabilities. Our findings are based on an empirical study that comprised 417 students, of whom 85 were students with LD. Based on sociometric analyses of all participating classes, we determined that students with LD were less integrated into the classroom in comparison to their peers without LD. The results of the sociometric analysis show statistically significant differences in the sociometric position between students with LD and students without LD. While students with LD were most frequently perceived as rejected, students without LD were seen as popular or average. In addition, students with LD see themselves as less socially self-efficient compared to their peers. The results of our study mostly refer to boys, because the sample comprised 359 boys and 58 girls. We believe that pro-inclusion teachers with appropriately developed strategies for strengthening students’ social skills, as well as positive attitudes and sufficient knowledge about the special needs of students can have a significant impact on the social acceptance of students with special needs in the classroom community.

    Johnsson, Kent O; Leifman, Anders; Berglund, Mats

    2008-01-01

    Changes in AUDIT score trajectories were examined in a student population during their first 4 years at a university, including high-risk consumers and a subsample of low-risk consumers. 359 students were selected for the present study, comprising all high-risk consumers (the 27% with highest scores, i.e. 11 for males and 7 for females) and a randomized sample of low-risk consumers (n = 177 and 182, respectively). The Alcohol Use Disorder Identification Test (AUDIT) was used as screening instrument. Trajectory analyses were made using a semiparametric group-based model. In the low-AUDIT group, five distinct trajectories were identified: three stable non-risky consumption groups (83%) and two increasing groups (17%; from non-risky to risky). In the high-AUDIT group, three groups were identified: two stable high groups (58%) and one decreasing group (from risky to non-risky consumption; 41%). In the integrated model, stable risky consumption comprised 16% of the total sample, decreasing consumption 11%, increasing consumption comprised 13% and stable non-risky consumption 60% of the sample. Gender influenced the trajectories. The pattern of changes in risk consumption is similar to that found in corresponding US studies. (c) 2008 S. Karger AG, Basel

For this, it should firstly be assessment personal values of nursing students. The purpose of the study was to determine the personal values of nursing students with respect to certain variables. The population of the study, which had a cross-sectional design, included all undergraduate students (n = 525) attending the nursing school. The sample group comprised 397 nursing students selected from among the nursing students attending a baccalaureate programme in Turkey using the disproportional cluster sampling method. Data were collected utilizing the Personal Information Form and Value Preferences Scale. The personal values of the students were found to be moral, social, financial/economic, aesthetic, political, religious and scientific/theoretical values. The study suggested that the age, year at school and economic level of the family affected the students' values. Values influence behaviours that are an essential component of humanistic nursing care. They are integral to professional socialization, evident in nursing care and fundamental decisions that affect practice. © 2012 Wiley Publishing Asia Pty Ltd.

    Carlton Parsons, Eileen; Miles, Rhea; Petersen, Michael

    2011-11-01

    Background: Research has primarily concentrated on adults' implicit theories about high quality science education for all students. Little work has considered the students' perspective. This study investigated high school students' implicit theories about what helped them learn science. Purpose: This study addressed (1) What characterizes high school students' implicit theories of what facilitates their learning of science?; (2) With respect to students' self-classifications as African American or European American and female or male, do differences exist in the students' implicit theories? Sample, design and methods: Students in an urban high school located in south-eastern United States were surveyed in 2006 about their thoughts on what helps them learn science. To confirm or disconfirm any differences, data from two different samples were analyzed. Responses of 112 African American and 118 European American students and responses from 297 European American students comprised the data for sample one and two, respectively. Results: Seven categories emerged from the deductive and inductive analyses of data: personal responsibility, learning arrangements, interest and knowledge, communication, student mastery, environmental responsiveness, and instructional strategies. Instructional strategies captured 82% and 80% of the data from sample one and two, respectively; consequently, this category was further subjected to Mann-Whitney statistical analysis at p ethnic differences. Significant differences did not exist for ethnicity but differences between females and males in sample one and sample two emerged. Conclusions: African American and European American students' implicit theories about instructional strategies that facilitated their science learning did not significantly differ but female and male students' implicit theories about instructional strategies that helped them learn science significantly differed. Because students attend and respond to what they think

    2015-12-01

    Full Text Available Introduction: Mobile phone use can be addictive for the young. However, little is known about the behavioral and biological effects of this addiction among the student population. Aim: The purpose of this study was to explore the effects of mobile phone use on the health behaviors and specific biomarkers in a sample of Greek students. Methods: Sample included 104 Nursing students from a stratified randomised sample. In 30 ran- domly selected out of the 104 students, melatonin and total antioxidant levels in saliva were also measured. Mobile phone dependence was estimated with the Mobile Phone Dependence Question- naire by Toda et al and general health with the GHQ-28. We used the Antioxidant assay kit-SIGMA to measure the total antioxidant levels and the anosoenzymic method ELISA (IBL kit to measure melatonine levels. Analysis was performed with SPSS v15.0 software. All hypothesis were tested at a p<0,05 level. Results: No statistical difference between genders was detected (p=0.182. High dependence was apparent in 13.5% of the sample, which correlated with worse general health (p=0.004, greater alcohol consumption (p=0.007, sleep disturbances (p=0.02 and worse nutritional habits (p=0.032. Moreover, high mobile dependent students exhibited higher concentration of early morning mel- atonin (p=0.07 and lower antioxidant concentration (p=0.333 in saliva, compared to low mobile dependent students. Conclusions: Excessive use of mobiles among students seems to correlate with unhealthy habits and impaired health. The effect in well known biomarkers may suggest the burden of the health of the student population. However, the long term effects on health require further investigation.

    1995-05-01

    Personality characteristics and lifestyle variables were assessed in two cohorts of second-year medical students at the University of Newcastle upon Tyne, UK as part of a psychopharmacology 'teach-in' in 1993 and 1994. The pooled sample included 186 students: 77 men, 109 women, mean age 20.4 +/- 1.8 years. Measures included the Eysenck Personality Questionnaire, the Hospital Anxiety Depression Scale, and a questionnaire concerning consumption of alcohol, tobacco, cannabis and other illicit drugs, and physical exercise. The results were compared, where possible, with a similar survey in Newcastle upon Tyne medical students in 1983 and 1984. Personality variables, prevalence of cigarette smoking, levels of caffeine consumption and participation in sports had not changed significantly over the decade. There appeared to be a modest overall increase in alcohol consumption and in the 1993 and 1994 cohorts of students, 25.5% of those who drank alcohol exceeded recommended low risk levels (comparable data not available for 1983 and 1984). Reported use of cannabis and other illicit drugs had more than doubled, and in the present survey 49.2% of students recorded using cannabis and 22% had tried other illicit drugs. Corresponding figures for 1983 and 1984 were 20.9% for cannabis and 3.3% for other illicit drugs. Anxiety levels were not measured in 1983 and 1984 but in the present survey 39.3% of the students had anxiety ratings within the clinically significant range. The high levels of alcohol consumption and illicit drug use, and the high anxiety ratings, in this sample of medical students are a cause for concern.(ABSTRACT TRUNCATED AT 250 WORDS)

    Full Text Available The main aim of present study was to examine the quality of college life (QCL based on the model developed by Sirgy et aI., (20] 0. The research design was correlational and the sample was comprises of 400 students from three universities including Tehran, Allameh and Kurdestan, which the respondents were selected using random sampling method. Quality of college life measurement was included three main subjects about college life as satisfaction with academic aspect, social aspect and facilities and services. In order to analysis the data structural equation modeling (SEM were employed. Findings indicated that the satisfaction with services and facilities has significant effect on satisfaction with academic and social aspects of college life. Moreover findings revealed that satisfaction with quality of college life has significant effect on satisfaction with overall life among students. Results indicated that the satisfaction with academic aspect and facilities and services among Tehran's university students is higher than Kurdestan's university students. Based on present findings the quality of universities may receive more attentions by higher education system especially in low income provinces such as Kurdestan. Lack of facilities resulted in decreasing the quality of academic aspect, social aspect and quality of college life. Low satisfaction with college life is leading to decreasing the overall life satisfaction which resulted in issues such as depression, frustration and anxiety among students.

    Over the past four years, the Franciscan University Counseling Center has reported a 231% increase in yearly visits, as well as a 173% increase in total yearly clients. This trend has been observed at many universities as mental health issues pose significant problems for many college students. The objective of this study was to investigate potential correlates of depression, anxiety, and stress in a sample of college students. The final analyzed sample consisted of 374 undergraduate students between the ages of 18 and 24 attending Franciscan University, Steubenville, Ohio. Subjects completed a survey consisting of demographic questions, a section instructing participants to rate the level of concern associated with challenges pertinent to daily life (e.g. academics, family, sleep), and the 21 question version of the Depression Anxiety Stress Scale (DASS21). The results indicated that the top three concerns were academic performance, pressure to succeed, and post-graduation plans. Demographically, the most stressed, anxious, and depressed students were transfers, upperclassmen, and those living off-campus. With the propensity for mental health issues to hinder the success of college students, it is vital that colleges continually evaluate the mental health of their students and tailor treatment programs to specifically target their needs.

    2017-02-01

    Educational institutions play an important role in encouraging students' engagement with course work. Educators are finding instruments to measure students' engagement in order to develop strategies to improve it. Little is known about the factor structure of the Utrecht Work Engagement Scale for Students among Chinese nursing students. The aim of this research was to examine the factor structure of the Utrecht Work Engagement Scale for Students via confirmatory factor analysis. The study used a cross-sectional design. A sample of 480 students from a nursing school in one Chinese university completed the Utrecht Work Engagement Scale for Students. Factor analysis was used to analyze the resulting data. The overall results of internal consistency reliability and confirmatory factor analysis provided evidence supporting the reliability and three-factor structure of the Utrecht Work Engagement Scale for Students. The total internal consistency reliability coefficients were 0.91. Model comparison tests indicated that an oblique factors model that permitted correlations between pairs of error terms fitted the data better than other first-order models. In addition, due to the three strongly intercorrelated factors, a second-order model was found to fit the data well, providing support for the factorial structure of the Utrecht Work Engagement Scale for Students. The findings of confirmatory factor analysis provided evidence supporting the reliability and three-factor structure of the Utrecht Work Engagement Scale for Students when evaluated with a Chinese nursing student sample in this study. Thus, it is appropriate to use The Utrecht Work Engagement Scale for Students in for assessing the engagement among Chinese nursing students. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Abstract The purpose of this study was to examine the prevalence of Internet addiction in a nationally representative sample of Chinese elementary and middle school students and to investigate Internet addiction among Internet users with different usages. The data were from the National Children's Study of China (NCSC) in which 24,013 fourth- to ninth-grade students were recruited from 100 counties in 31 provinces in China. Only 54.2% of the students had accessed the Internet. According to the criteria of Young's Diagnostic Questionnaire (YDQ), an eight-item instrument, the prevalence of Internet addiction in the total sample was 6.3%, and among Internet users was 11.7%. Among the Internet users, males (14.8%) and rural students (12.1%) reported Internet addiction more than females (7.0%) and urban students (10.6%). The percentage of Internet addicts in elementary school students (11.5%) was not significantly lower than the percentage of middle school students (11.9%). There was no statistically significant difference between the four geographical regions (9.6%, 11.5%, 12.3%, 11.1%) characterized by different levels of economy, health, education, and social environment. As the frequency of Internet use and time spent online per week increased, the percentage of Internet addicts increased. When considering the location and purpose of Internet use, the percentage of Internet addicts was highest in adolescents typically surfing in Internet cafes (18.1%) and playing Internet games (22.5%).

    Hair samples from junior high school students in metropolitan areas of Taichung, Taiwan were tested for a total of 13 elements, Al, Ag, Br, Cl, Cr, Fe, K, La, Mn, Na, Sc, Se, and Zn by instrumental neutron activation analysis (INAA) to establish seasonal variations, gender and environmental exposures. The seasonal variations of hairs in 39 healthy students (18 males and 21 females; age 13.3 ± 0.4 years; height, 158.0 ± 4.1 cm; weight, 53.4 ± 5.7 kg) were collected at 1.5-month intervals for 1 year starting from late August, 2008. The concentrations of the above elements varied from 10 3 to 10 -2 μg g -1 at different sampling times. A quantified index of agreement (AT) was introduced to help classify the elements. A smaller AT indicated highly consistent quantities of specific metals in the hair while a larger AT indicated increased fluctuation, i.e., less agreement. The different ATs in various hair samples were discussed. The concentrations of these elements are compared with the data in the literature. (author)

  2. Beyond the "science of sophomores": does the rational choice explanation of crime generalize from university students to an actual offender sample?

    Science.gov (United States)

    Bouffard, Jeff; Bry, Jeff; Smith, Shamayne; Bry, Rhonda

    2008-12-01

    Much of the criminological literature testing rational choice theory has utilized hypothetical scenarios presented to university students. Although this research generally supports rational choice theory, a common criticism is that conclusions from these studies may not generalize to samples of actual offenders. This study proceeds to examine this issue in two steps. First, a traditional sample of university students is examined to determine how various costs and benefits relate to their hypothetical likelihood of offending. Then the same data collection procedures are employed with a somewhat different sample of younger, adjudicated, and institutionalized offenders to determine whether the conclusions drawn from the student sample generalize to this offender sample. Results generally suggest that the content and process of hypothetical criminal decision making differ in the sample of known offenders relative to the university students. Limitations of the current study, as well as suggestions for future research, are discussed.

    Tobacco smoking rates are increasing in developing countries and so are tobacco-related chronic diseases. Reported figures from the WHO show rates of smoking in Egypt as high as 20% but limited information is available about smoking specifically among physicians and medical students. Final-year medical students of Cairo University were surveyed regarding their tobacco behavior and attitudes using a modified Global Health Professions Student Survey. We approached 220 students by randomly selecting clinical units into which they were assigned and requested completion of the survey. Ever users of some form of tobacco comprised 46.7% of students sampled, current users of cigarettes comprised 17.4%, and current users of water pipe 'sheesha' comprised 17.6%. The vast majority (87.7%) of students believed that smoking is a public health problem in Cairo and supported restriction of tobacco. Yet, only 58.5% stated that they were taught it is important for physicians to provide tobacco education materials to patients. Among ever users of cigarettes, 54.4% believed health professionals do not serve as health role models for patients, and only a small percentage of all students (34.2%) stated that they had received some form of training on smoking cessation in their medical curriculum to be able to instruct patients. A high rate of smoking was revealed among medical students in Cairo. Overall, approximately 23.4% of students were currently smoking cigarettes and/or sheesha, and 46.7% were ever users of some form of tobacco. A formal antitobacco program for medical students should be incorporated into their medical curriculum to change the attitudes of medical students and overcome the anticipated increase in chronic diseases in Egypt.

    Although the association between acculturation and substance use among Latino groups is important, it is often understudied, especially within specific Latino groups living in geographically distinct communities, such as the Mexican American population in South Texas. The researchers of this study aimed to better understand the effect of acculturation on substance use and alcohol dependence in a Mexican American college student population. This survey study investigated the correlation between acculturation and substance use and dependence by using the Vancouver Index of Acculturation (VIA), items related to substance use (nicotine, marijuana, and cocaine) in a Mexican American college student sample (N = 1,494), and the Short Alcohol Dependence Data Questionnaire (SADD; N = 715). The study was conducted in the Texas-Mexico border region. The results suggest that higher levels of acculturation do not predict increased drug use or alcohol dependence in the Mexican American college students. However, acculturation was found to be associated with lower use of cocaine and marijuana. The discussion examines commonalities and differences in drug use and dependence. Specifically, acculturation seems to have an inverse relationship to substance use and may serve as a protective factor to licit and illicit drug use among Mexican American college students.

    Teamwork and collaboration are regarded as important goals for health and social care education and inter-professional education (IPE) the vehicle to achieve this. However, there is debate concerning the best strategies for implementation, location and delivery of IPE. This exploratory study was undertaken to anticipate some of the problems of implementing a pre-qualification IPE programme for Children's Branch nursing students and medical students undertaking a Paediatrics module and to identify strategies to maximise success. A modified version of the readiness for inter-professional learning scale (RIPLS), including additional open-ended questions, was used with a convenient, purposeful sample of 20 medical and 10 nursing students. Both groups regarded learning team-working skills as important. Medical students regarded IPE as a means to learn about team-work and professional roles otherwise they indicated a preference for a discipline-based approach. Both groups were found to have acquired a strong sense of their own professional role. Both perceived IPE as disadvantageous if it impeded their own professional learning. Results also highlighted the importance of class size, stage of learning, appropriate skills and subject in IPE planning. We conclude that a small exploratory study can provide a useful guide for programme planning and additional qualitative data can enable a more comprehensive explanation of results.

    Recently, the practice of active learning has spread, increasingly recognized as an essential component of academic studies. Classes incorporating small group discussion (SGD) are conducted at many universities. At present, assessments of the effectiveness of SGD have mostly involved evaluation by questionnaires conducted by teachers, by peer assessment, and by self-evaluation of students. However, qualitative data, such as open-ended descriptions by students, have not been widely evaluated. As a result, we have been unable to analyze the processes and methods involved in how students acquire knowledge in SGD. In recent years, due to advances in information and communication technology (ICT), text mining has enabled the analysis of qualitative data. We therefore investigated whether the introduction of a learning system comprising the jigsaw method and problem-based learning (PBL) would improve student attitudes toward learning; we did this by text mining analysis of the content of student reports. We found that by applying the jigsaw method before PBL, we were able to improve student attitudes toward learning and increase the depth of their understanding of the area of study as a result of working with others. The use of text mining to analyze qualitative data also allowed us to understand the processes and methods by which students acquired knowledge in SGD and also changes in students' understanding and performance based on improvements to the class. This finding suggests that the use of text mining to analyze qualitative data could enable teachers to evaluate the effectiveness of various methods employed to improve learning.

    Occupational therapy relies primarily on communication between the therapist and client for effective intervention. Adequate communication may be influenced by language and cultural differences between the therapist and client. Cultural competence in relation to language and culture is thus a vital part in practice. Limited research exists on cultural competence in occupational therapy students. This study thus aimed to explore the cultural competence of final year students and their perceptions of their own cultural competence, with respect to language and culture in their practice as students. An explorative qualitative study design was utilised with a nonprobability purposeful sample of 21 final year undergraduate students at a tertiary institute in South Africa. Three focus groups were conducted, comprising between 6 and 8 students in each group. Thematic analysis using inductive reasoning was undertaken in order to analyse the students' experiences and understanding of cultural competence. Findings of the study suggest that cultural competence, in relation to language and culture, influences the occupational therapy intervention process. It was shown to both positively and negatively influence intervention through supporting or hindering rapport building, client centeredness, and effective intervention.

    2010-06-01

    The objective of this research is to obtain accurate drinking norms for students living in the university residences in preparation for future social norms interventions that would allow individual students to compare their drinking to an appropriate reference group. Random cluster sampling was used to obtain data from 318 residence students who completed the Alcohol Use Disorders Identification Test (AUDIT), a brief, reliable and valid screening measure designed by the World Health Organisation (Babor et al. 2001). The Cronbach alpha coefficient of 0.83 reported for this multicultural sample is high, suggesting that the AUDIT may be reliably used in this and similar contexts. Normative scores are reported in the form of percentiles. Comparisons between the portions of students drinking safely and hazardously according to race and gender indicate that while male students are drinking no more hazardously than female students, white students drink far more hazardously than black students. These differences suggest that both race- and gender-specific norms would be essential for an effective social norms intervention in this multicultural South African context. Finally, the racialised drinking patterns might reflect an informal segregation of social space at Rhodes University.

    Full Text Available Limited data are available from Jordan examining patterns of tobacco use among adolescents, or how use is related to health perceptions. This study aims to estimate the prevalence of tobacco use and to assess the relationship between use and health-related perceptions. A cross-sectional survey was conducted among a sample of 11–18 year old school students from a major governorate in Jordan. Using a multistage random sampling 1050 students were selected. Students were categorized as non-smokers, cigarette-only smokers, waterpipe-only smokers, or dual smokers. Rates of waterpipe-only and cigarette-only smoking were 7% and 3%, respectively, and were similar for boys and girls. In contrast, the rate of dual use was much higher than for single product use and was double in girls compared to boys (34% vs. 17%. Dual-smokers were significantly more likely to think that it is safe to smoke as long as the person intends to quit within two years compared to non-smokers, and had lower self-rated health status than other groups. This is the first study among Arab adolescents to document high rates of dual tobacco use, especially pronounced among girls. The study findings have significant implications for designing tobacco smoking prevention programs for school health settings.

    Associations between test anxiety, academic self-efficacy (ASE), and social support through social media have not been fully explored. The purposes were to explore associations between test anxiety, ASE, and social support from social media and to examine differences in test anxiety by students' year of studies and cultural background. This study used a cross-sectional, descriptive design. The sample comprised first- and fourth-year nursing students (n = 240) attending a baccalaureate nursing program in Israel. Higher ASE and support through social media were related to lower test anxiety. Fourth-year students and Jewish students had higher ASE than first-year and Arab students, who received more support on social media than Jewish students. Developing learning strategies designed to increase students' ASE and reduce test anxiety is warranted. Social media as an educational tool can be adopted for this purpose.

    Full Text Available Personal financial education is primordial in society, as it influences directly the economic decisions of individuals. This way, the present survey, based on a project that developed and implemented a financial education course for young people, aims to measure the financial literacy level of the students, before and after the course. The sample comprised 302 elementary school students from public schools in Santa Maria, aged between 11 and 17. The results show that the students had a low financial knowledge, which improved after the course, and the variables “math grades”, “parental education” and “total household monthly incomes” are significant to the financial literacy level of students.

Our analysis is built on 2016 data from GUESSS project – an extensive academic study on student entrepreneurship, and our main sample comprises of 15,971 V4 university students. Potential drivers from individual human and social capital characteristics, perceived institutional support, and demographic attributes are examined, using the logistic regression method. Applying a unique perspective and distinguishing between different types of student entrepreneurs, we focus especially on promisingly sustainable student entrepreneurs with already active businesses, who plan to continue them after completing their studies. According to our results, gender (being a male, increasing age together with dropping number of years to finish studies, intensity of entrepreneurship education, studying in a business-related field, and having entrepreneurial parents significantly drive student entrepreneurship inclinations during their university studies.

    Recent violent attacks on college campuses in the United States have sparked discussions regarding the prevalence of psychiatric disorders and the perpetration of violence among college students. While previous studies have examined the potential association between mental health problems and violent behavior, the overall pattern of findings flowing from this literature remain mixed and no previous studies have examined such associations among college students. The current study makes use of a nationally representative sample of 3,929 college students from the National Epidemiologic Study on Alcohol and Related Conditions (NESARC) to examine the prevalence of seven violent behaviors and 19 psychiatric disorder diagnoses tapping mood, anxiety, personality, and substance use disorders. Associations between individual and composite psychiatric disorder diagnoses and violent behaviors were also examined. Additional analyses were adjusted for the comorbidity of multiple psychiatric diagnoses. The results revealed that college students were less likely to have engaged in violent behavior relative to the non-student sample, but a substantial portion of college students had engaged in violent behavior. Age- and sex-standardized prevalence rates indicated that more than 21% of college students reported at least one violent act. In addition, more than 36% of college students had at least one diagnosable psychiatric disorder. Finally, the prevalence of one or more psychiatric disorders significantly increased the odds of violent behavior within the college student sample. These findings indicate that violence and psychiatric disorders are prevalent on college campuses in the United States, though perhaps less so than in the general population. In addition, college students who have diagnosable psychiatric disorders are significantly more likely to engage in various forms of violent behavior.

    2010-04-01

    This study examined alternative seven-, five-, and three-factor structures for the Academic Motivation Scale, with data from a large convenience sample of 2,078 students matriculating in various business courses at three AACSB-accredited regional comprehensive universities. In addition, the invariance of the scale's factor structure between male and female students and between undergraduate and Master's of Business Administration students was investigated. Finally, the internal consistency of the items loading on each of the seven AMS subscales was assessed as well as whether the correlations among the subscales supported a continuum of self-determination. Results for the full sample as well as the targeted subpopulations supported the seven factor configuration of the scale with adequate model fit achieved for all but the MBA student group. The data also generated acceptable internal consistency statistics for all of the subscales. However, in line with a number of previous studies, the correlations between subscales failed to fully support the scale's simplex structure as proposed by self-determination theory.

  5. Energy drink use, problem drinking and drinking motives in a diverse sample of Alaskan college students

    2013-08-01

    Full Text Available Background. Recent research has identified the use of caffeinated energy drinks as a common, potentially risky behaviour among college students that is linked to alcohol misuse and consequences. Research also suggests that energy drink consumption is related to other risky behaviours such as tobacco use, marijuana use and risky sexual activity. Objective. This research sought to examine the associations between frequency of energy drink consumption and problematic alcohol use, alcohol-related consequences, symptoms of alcohol dependence and drinking motives in an ethnically diverse sample of college students in Alaska. We also sought to examine whether ethnic group moderated these associations in the present sample of White, Alaska Native/American Indian and other ethnic minority college students. Design. A paper-and-pencil self-report questionnaire was completed by a sample of 298 college students. Analysis of covariance (ANCOVA was used to examine the effects of energy drink use, ethnic group and energy drink by ethnic group interactions on alcohol outcomes after controlling for variance attributed to gender, age and frequency of binge drinking. Results. Greater energy drink consumption was significantly associated with greater hazardous drinking, alcohol consequences, alcohol dependence symptoms, drinking for enhancement motives and drinking to cope. There were no main effects of ethnic group, and there were no significant energy drink by ethnic group interactions. Conclusion. These findings replicate those of other studies examining the associations between energy drink use and alcohol problems, but contrary to previous research we did not find ethnic minority status to be protective. It is possible that energy drink consumption may serve as a marker for other health risk behaviours among students of various ethnic groups.

    Effects of full-time ability grouping on students' academic self-concept (ASC) and mathematics achievement were investigated in the first 3 years of secondary school (four waves of measurement; students' average age at first wave: 10.5 years). Students were primarily from middle and upper class families living in southern Germany. The study sample comprised 148 (60% male) students from 14 gifted classes and 148 (57% male) students from 25 regular classes (matched by propensity score matching). Data analyses involved multilevel and latent growth curve analyses. Findings revealed no evidence for contrast effects of class-average achievement or assimilation effects of class type on students' ASC. ASC remained stable over time. Students in gifted classes showed higher achievement gains than students in regular classes. © 2017 The Authors. Child Development © 2017 Society for Research in Child Development, Inc.

    Full Text Available The current interest in introducing the dual education system into Serbian secondary education has drawn our attention to the question of students' self-perception in the process of practical teaching. The idea that underpins this paper is the supposition that students are affectively engaged with the work activities they perform. The Utrecht Work Engagement Scale (UWES (Schaufeli et al., 2002 has been used for assessing students' work engagement in practical teaching. A study was conducted to examine the differences between high school students with mild intellectual disabilities and those with typical development with regard to aspects of work engagement defined as Energy, Commitment and Absorption. The sample was comprised of 248 students of vocational high schools in Serbia of both genders, of whom 111 with intellectual disabilities and 137 with typical development. The findings indicate that students with mild intellectual disabilities tend to rate their engagement in practical teaching more positively (t=7,457; p=0,001 than students with typical development. The paper provides a detailed analysis of the pedagogical implications of these findings and also outlines the limitations of the study, thus pointing the way for future research on this or related issues.

    In the Greek society, there is a strong cultural tendency to overestimate the value of University studies. So students are under high emotional pressure during the long lasting period of the preparation for the university entrance exams. The aim of the present study was to evaluate the level of anxiety in a general adolescent population of senior high school students in Athens, Greece. Also to examine the association between the anxiety's severity with various demographic and socio-cultural factors, as well as with academic performance, extracurricular activities, sleep duration and presence of somatic problems. The sample consisted of 696 adolescent students of three Senior High Schools (SHS) (391 girls and 305 boys). Two of the schools were general education institutions (GE1 and GE2, N=450), while the third was a technical one (TE, N=246). The school sample was selected to reflect the proportion between the two different types of SHSs in Athens as well as other major urban areas in Greece. The State-Trait Anxiety Inventory was administered and personal data were also collected. Statistical significance was set at pmiddle for 154, high for 195 and mother's was low for 135, middle for 417, high for 140. The average sleep duration was 7.5 hours per day (SD=1.3). The average time per week spent in school related activities was 7.94 hours (SD=7.56) and in extracurricular activities was 9.02 hours (SD=12.44). 107 adolescents reported somatic complaints in the last year The academic achievement was poor for 233, good for 264, excellent for 196 students. Adolescents with extracurricular activities for more than 11 hours per week had lower scores, both on State and Trait scales. More hours in school-related activities were associated with greater levels of Trait anxiety. Adolescents whose father had a high educational level had lower scores on State anxiety compared to those whose father had a low educational level. Adolescents who reported the presence of somatic

    This is a descriptive study examining nursing students' perceptions of the environmental risks and their environmental attitudes. The study population comprised 2364 nursing students studying at universities in Istanbul in the fall semester of the 2012-2013 academic year. The sampling group was formed by 778 students which were selected by a stratified random sampling procedure. The data were collected using "The Student Personal Information Form", "The Environmental Risk Perception Scale" and "The Environmental Attitudes Scale". The students' mean score on perceptions of environmental risk was 6.04 ± 0.81(min 2.56; max 7.00) and the mean score of their environmental attitudes was 4.02 ± 0.47(min 2.28; max 5.00). It was determined that factors such as gender, interest in environmental issues, endorsement of the college course on environment as necessary, and participation in an environmental activity and awareness of non-government environmental organizations affected the environmental risk perception and environmental attitudes. A moderate positive relationship (r = 0.366, p environmental risk perceptions and their environmental attitudes. Effective environmental education should be planned at all stages of the nursing education.

    The aim of the present study was to investigate gender differences in students' health habits and motivation for a healthy lifestyle. The sample of students comprised a probability systematic stratified sample from each department at a small university in the south-west of Sweden (n = 479). A questionnaire created for this study was used for data collection. Self-rated health was measured by number of health complaints, where good health was defined as having less than three health complaints during the last month. A healthy lifestyle index was computed on habits related to smoking, alcohol consumption, food habits, physical activity and stress. Female students had healthier habits related to alcohol consumption and nutrition but were more stressed. Male students showed a high level of overweight and obesity and were less interested in nutrition advice and health enhancing activities. The gender differences are discussed in relation to the impact of stress on female students' health, and the risk for male students in having unhealthy nutritional habits in combination with being physically inactive and drinking too much alcohol.

    Full Text Available The analysis of the motivation experiences of students in the conditions of inclusive education determines teaching procedures considerably. The main aim of this research was to determine whether there were any difference in motivation experience between students with learning and developmental difficulties and the students without these difficulties, and whether there is any correlation of academic success and motivation experiences between these two groups. The sample comprised 87 students of the fifth grade (24.13% students with learning and developmental difficulties, and 75.86% students without these difficulties. The examination of motivation experience was carried out by the Scale for Estimating Extrinsic and Intrinsic Motivation. Statistics analyses show that there are differences in experiencing intrinsic and extrinsic motivation among students with and without learning and developmental difficulties. Learning difficulties correlate with lower academic achievement at the end of the fourth grade. As academic success increases the motivation experience decreases in both groups. The obtained results stress the importance of interventions by teachers and other school professionals in order to maintain motivational levels of all students. The results of this research highlight the quality of assessment system of academic achievement of all students and suggest further researching how and which way teachers understand and apply different functions of assessment.

    Full Text Available The study examined the teachers' skills in identification and management of secondary school students' talent in Ondo State. The study adopted a descriptive survey research design for the study. The population of the study com-prised 3462 secondary schools' teachers in Ondo Central Senatorial District while the sample consisted of 360 teachers. Multi-stage sampling technique was used to select the sample. The first stage was a simple random technique to select three Local Government Areas from six Local Government Areas in the District. Proportionate sampling technique was used to select 24 secondary schools from the three Local Government Areas selected. The last stage in-volved using proportionate stratified random sampling to select a total of 360 teachers. Data for the study were collected using questionnaire tagged Teachers Shills in Identifying Students' Talents Questionnaire (TSITQ.Data collected were analysed using frequency count and simple percentages. The results showed that the predominant skill used by teachers in identifying students' talents were Guidance and Counselling, Motivation, Creative teaching and Pedagogical. It was found out that motivational strategy (in form of gifts, prizes and scholarship was predominantly used by teachers in managing students' talents followed by independent study, creative teaching and pro-gramme planning. Based on the findings of the study it was therefore recommended that teachers should improve on their strategies such as independent study, creative teaching, individualised instructions and programme planning in managing secondary school students' talents.

    Developing professional values among undergraduate nursing students is important since such values are a significant predictor of quality care, clients' recognition, and therefore nurses' job satisfaction. This study explored South Korean nursing students' perception of nursing professional values (NPV) and compared the NPV scores between groups according to participants' demographic characteristics. The study participants comprised of 529 students, mostly female (96.4%), with a mean age of 22.29years, sampled from six universities throughout the country. The NPV scores, measured with the 29-item Likert scale developed by Yeun et al. (2005), were significantly higher in students who entered nursing schools following their aptitude or desire for professional job than in those who entered the schools just because their entrance exam scores were sufficient. The NPV scores were also higher in students who were planning to pursue graduate study than in those who had not yet decided. The NPV scores were significantly different between the six regions, suggesting needs of in-depth studies to understand the underlying reasons. The NPV scores were not correlated, at the .05 level of significance, with academic year, gender, or academic performance. 2010 Elsevier Ltd. All rights reserved.

    Full Text Available Self-concept has been found to play a key role in academic and psychosocial outcomes for students. Appreciating the factors that have a bearing upon self-concept may be of particular importance for Aboriginal students, many of whom experience poorer outcomes than non-Aboriginal Canadians. The current study explored the relationships between multidimensional self-concept, perceived strengths and academic achievement among a sample Aboriginal and non-Aboriginal students. Results indicated that perceived self-concept and strengths were largely similar across groups. However, students in the two groups drew on different strengths to comprise their general self-concept. Findings are explored within the context of existing research and theory.

    Full Text Available This emerging initiative stemmed from an Office for Learning and Teaching Project (OLT project, Transforming Practice Programme 2016: Student Engagement: Students as Partners in Teaching and Learning. The initiative, trialed in semester two, 2016, involved the selection and training of two experienced students to be leaders of a Closed Facebook ‘students-only’ community which provided advice and triaged queries to appropriate channels. The evaluative processes comprised a participatory action research methodology. Two student leaders who facilitated the Closed Facebook and four academic staff of the project were the participants. The findings demonstrate that the Closed Facebook students-only site provided a safe space, outside the formal learning/classroom environment, where student participants were able to ask and share knowledge. The informal student-for-student learning community complemented the formal structure by facilitating the opportunity for students to become ‘experts’ as university students as they move-through their learning journey.

  6. College Student Samples Are Not Always Equivalent: The Magnitude of Personality Differences Across Colleges and Universities.

    2017-04-01

    This research examined the magnitude of personality differences across different colleges and universities to understand (a) how much students at different colleges vary from one another and (b) whether there are site-level variables that can explain observed differences. Nearly 8,600 students at 30 colleges and universities completed a Big Five personality trait measure. Site-level information was obtained from the Integrated Postsecondary Education System database (U.S. Department of Education). Multilevel models revealed that each of the Big Five traits showed significant between-site variability, even after accounting for individual-level demographic differences. Some site-level variables (e.g., enrollment size, requiring letters of recommendation) explained between-site differences in traits, but many tests were not statistically significant. Student samples at different universities differed in terms of average levels of Big Five personality domains. This raises the possibility that personality differences may explain differences in research results obtained when studying students at different colleges and universities. Furthermore, results suggest that research that compares findings for only a few sites (e.g., much cross-cultural research) runs the risk of overgeneralizing differences between specific samples to broader group differences. These results underscore the value of multisite collaborative research efforts to enhance psychological research. © 2015 Wiley Periodicals, Inc.

    The study aimed to detect the frequency of social phobia symptoms in a sample of German medical students and to compare students with and without these symptoms related to interpersonal characteristics. 525 students filled out a battery of self-report questionnaires consisting of the LSAS (Liebowitz Social Anxiety Scale), the SPAI (Social Phobia Anxiety Inventory), the IIP-32 (Inventar of interpersonal problems) and the IIM (Inventar of interpersonal motives). Relevant social phobia symptoms were found in 12.2%. Students with symptoms of social phobia differed significantly in subscales of the IIP and the IIM. Students with symptoms of social phobia also had higher scores for interpersonal problems especially related to the main issue of being too "socially avoidant". © Georg Thieme Verlag KG Stuttgart · New York.

    Today's healthcare environment is often characterized by an ethically demanding work situation, and nursing students need to prepare to meet ethical challenges in their future role. Moral sensitivity is an important aspect of the ethical decision-making process, but little is known regarding nursing students' moral sensitivity and its possible development during nursing education. The aims of this study were to investigate moral sensitivity among nursing students, differences in moral sensitivity according to sample sub-group, and the relation between demographic characteristics of nursing students and moral sensitivity. A convenience sample of 299 nursing students from one university completed a questionnaire comprising questions about demographic information and the revised Moral Sensitivity Questionnaire. With the use of SPSS, non-parametric statistics, including logistic regression models, were used to investigate the relationship between demographic characteristics and moral sensitivity. Ethical considerations: The study followed the regulations according to the Swedish Ethical Review Act and was reviewed by the Ethics Committee of South-East Sweden. The findings showed that mean scores of nursing students' moral sensitivity were found in the middle to upper segment of the rating scale. Multivariate analysis showed that gender (odds ratio = 3.32), age (odds ratio = 2.09; 1.73), and parental status (odds ratio = 0.31) were of relevance to nursing students' moral sensitivity. Academic year was found to be unrelated to moral sensitivity. These demographic aspects should be considered when designing ethics education for nursing students. Future studies should continue to investigate moral sensitivity in nursing students, such as if and how various pedagogical strategies in ethics may contribute to moral sensitivity in nursing students.

    2017-07-01

    Full Text Available Supervisors are expected to observe how student teachers prepare deliver the lesson and conduct themselves as members of teaching profession and are expected to advise the students on how to improve their teaching skills. The present study is a descriptive survey which sought to analyze student teachers perception towards teaching practice as an exercise for grading or improvement and examine student teachers perception towards student-supervisor comments during discussion after classroom assessment. The sample comprised of 50 second year Diploma in Education who had undergone teaching practice in 2016. The students were purposefully sampled. In purposeful sampling the researcher selects the participants because they possess particular characteristics or knowledge being sought. A questionnaire was used to collect data for this study. The findings indicated that majority of student teachers who participated in the teaching practice perceived that the supervisors gave grades which did not reflect the comments made about the teaching performance of the student teacher. Based on the findings recommendations were made among others that assessment should match the comments on areas needing improvement and meaningful accompanying comments should be made to guide student teachers in the desired directions during teaching practice encourage student teachers to try harder or to give credit for work done well.

    To determine how anxiety, depression, and somatic symptoms are related in a sample of university students in northern Mexico. An exploratory study was conducted through self-administered questionnaires applied to a convenience sample of 506 psychology students at two universities in Monterrey, in the state of Nuevo León, Mexico. To evaluate somatic symptoms, the Patient Health Questionnaire was used; for depression, the Beck Depression Inventory; and for anxiety, the Social Anxiety Scale for Adolescents. Spearman's correlation was used to determine to what extent the associations among the variables were significant. The Kruskal-Wallis test was used to compare anxiety and depression levels between groups of students organized by severity of somatic symptoms. Of the participants, 129 (25.5%) presented somatic symptoms that were of medium intensity or severe; just 4 (0.8%) had severe depression; and only 2 (0.4%) students presented anxiety levels over 75% of the scale maximum. The severity of somatic symptoms increased in step with anxiety and depression levels. The somatic symptoms occurring most frequently and of greatest concern among the study sample were: headache, menstrual pain, and backache, as well as feeling tired and having difficulty sleeping. The direct association between the severity of somatic symptoms and depression and anxiety was confirmed. It is recommended that all treatment and/or prevention programs addressing one of these conditions, include the other two as well. Programs specifically aimed at university youth should be implemented.

    2017-01-01

    We tested a model consistent with the notion that perceived burdensomeness and thwarted belongingness mediate the association between future orientation and suicide risk (viz., depressive symptoms and suicide ideation) in college students. The sample was comprised of 195 Hungarian college students. Results indicated that the negative associations found between future orientation and suicide risk outcomes were accounted for by both perceived burdensomeness and thwarted belongingness. The present findings highlight the importance of studying positive future cognitions in suicide risk and provide support for perceived burdensomeness and thwarted belongingness as potential proximal mechanisms associated with heighted suicide risk in adults.

    Globalization is a part of modern life. Sharing a common set of professional nursing values is critical in this global environment. The purpose of this research was to examine the professional values of nursing students from two distinct cultural perspectives. Nurse educators in Taiwan partnered with nurse educators in the United States to compare professional values of their respective graduating nursing students. The American Nurses Association Code of Ethics served as the philosophical framework for this examination. The convenience sample comprised 94 Taiwanese students and 168 US students. Both groups reported high scores on an overall measure of values. They did differ substantially on the relative importance of individual items related to advocacy, competence, education, self-evaluation, professional advancement, and professional associations. Global implications for the collaborative practice of nurses from different cultures working together can be improved by first recognizing and then attending to these differences in value priorities.

    2011-07-30

    Recent evidence suggests that normal-range paranoid ideation may be particularly likely to develop in individuals disposed to both social anxiety and perceptual anomalies. This study was designed to test the hypothesis that among college students in an unselected sample, social anxiety and experience of perceptual anomalies would not only each independently predict the experience of self-reported paranoid ideation, but would also interact to predict paranoid patterns of thought. A diverse sample of 644 students completed a large battery of self-report measures, as well as the five-factor Paranoia/Suspiciousness Questionnaire (PSQ). We conducted hierarchical multiple regression analyses predicting scores on each PSQ factor from responses on measures of social anxiety, perceptual aberration, and the interaction between the two constructs. Current general negative affect was covaried in all analyses. We found that both social anxiety and perceptual aberrations, along with negative affect, predicted multiple dimensions of paranoia as measured by the PSQ; the two constructs did not, however, interact significantly to predict any dimensions. Our findings suggest that perceptual aberration and anxiety may contribute to normal-range paranoid ideation in an additive rather than an interactive manner. Copyright © 2011 Elsevier Ltd.

    Full Text Available Introduction. Medical students experience significant psychological stress and are therefore at higher risk of using sedatives. There are currently no studies describing the prevalence of sedative drug use among medical students in Saudi Arabia. The aim of this study was to evaluate the prevalence and factors associated with sedative drug use among medical students in Saudi Arabia. Materials and Methods. A cross-sectional convenience sampling study gathered data by anonymous questionnaire from students enrolled at the King Saud University College of Medicine in 2011. The questionnaires collected data regarding social and demographic variables, sleep patterns, and the use of stimulant and sedative drugs since enrollment. Sedatives were defined as any pharmaceutical preparations that induce sleep. Results and Discussion. Of the 729 students who returned questionnaires, 17.0% reported sedative drug use at some time since enrollment. Higher academic year, lower grade point average, regular exercise, fewer hours of sleep per day, poorer quality of sleep, and the presence of sleeping disorders were found to be significantly associated with sedative drug use. Conclusions. Further study is required to increase our understanding of sedative drug use patterns in this relatively high-risk group, as such understanding will help in the development of early intervention programs.

    2014-01-01

    In this study our goal was to examine the hierarchical structure of personality pathology as conceptualized by Harkness and McNulty's (1994) Personality Psychopathology Five (PSY-5) model, as recently operationalized by the MMPI-2-RF (Ben-Porath & Tellegen, 2011) PSY-5r scales. We used Goldberg's (2006) "bass-ackwards" method to obtain factor structure using PSY-5r item data, successively extracting from 1 to 5 factors in a sample of psychiatric patients (n = 1,000) and a sample of university undergraduate students (n = 1,331). Participants from these samples had completed either the MMPI-2 or the MMPI-2-RF. The results were mostly consistent across the 2 samples, with some differences at the 3-factor level. In the patient sample a factor structure representing 3 broad psychopathology domains (internalizing, externalizing, and psychoticism) emerged; in the student sample the 3-factor level represented what is more commonly observed in "normal-range" personality models (negative emotionality, introversion, and disconstraint). At the 5-factor level the basic structure was similar across the 2 samples and represented well the PSY-5r domains.

    Full Text Available The aim of the study was to examine the relationship between trait emotional intelligence (EI and the Big Five factors of personality in two samples of Croatian and Slovenian university students. If EI is to be of significant value, it must measure something unique and distinct from standard personality traits. The Croatian sample consisted of 257 undergraduate students from University of Rijeka and Osijek and in Slovene sample there were 171 undergraduate students from University of Ljubljana. Participants filled out the Emotional Skills and Competences Questionnaire (ESCQ, Takšić, 1998 and the Big Five Inventory (BFI; John, Donahue, & Kentle, 1991. After controlling for nationality and gender, the Big Five explained up to 33% of the variance of EI. For the Perceive and Understand Emotions Scale only openness and extraversion explain important part of the variance; for the Express and Label Emotions Scale extraversion and conscientiousness are important predictors. The Big Five traits are able to explain the highest proportion of the variance in the Manage and Regulate Emotion Scale; neuroticism is the strongest predictor, but extraversion and conscientiousness also predict important part of the variance. Although high, this percentage of explained variance does not put in question the discriminant validity of EI questionnaire.

    Full Text Available The Malaysian government is rigorously drawing up strategies to increase the already existing 60,000 foreign students currently studying in the country (The Star, 2009. With the influx of more foreign students and with English as the medium of instruction in local higher aspects that drive and/or deter them in learning English would be beneficial. The sample for this study (N=115 comprised of international students from China, Iran, Kazakhstan, Indonesia, Korea, Vietnam, Maldives and the Middle East undertaking an Intensive English course at a local private college. Data collection was done via questionnaire which was designed based on a review of existing instruments in the field. Results show that orientation towards learning English does not vary according to nationality and gender; however, students from China and Korea tend to be more inclined towards instrumental orientation, while students from Kazakhstan and Iran are more inclined towards integrative orientation. Based on the findings, this paper also proffers recommendations for local higher education institutions to enhance ELT practices for incoming international students.

  8. Giving Students Control over Their Learning; from Self-guided Museum Visits and Field Trips to Using Scanning Technology to Link Content to Earth Samples

    While it may seem counterintuitive, sometimes stepping back is one of the more effective pedagogical approaches instructors can make. On museum visits, an instructor's presence fundamentally alters students' experiences and can curtail student learning by limiting questions or discouraging students from exploring their own interests. Students often rely on the instructor and become passive observers, rather than engaged learners. As an alternative to instructor-led visits, self-guided student explorations of museum exhibits proved to be both popular and pedagogically effective. On pre-instruction and post-instruction surveys, these ungraded, self-guided explorations match or exceed the efficacy of traditional graded lab instruction and completely eclipse gains normally achieved by traditional lecture instruction. In addition, these explorations achieve the remarkable goal of integrating undergraduate earth science instruction into students' social lives. Based on the success of the self-guided museum explorations, this fall saw the debut of an attempt to expand this concept to field experiences. A self-guided student field exploration of Saint Anthony Falls focuses on the intersections of geological processes with human history. Students explore the waterfalls' evolution, its early interpretation by 18th and 19th century Dakota and Euro-America societies, and its subsequent social and economic impacts on Upper Midwest societies. Self-guided explorations allow students to explore field settings on their own or with friends and family in a more relaxed manner. At the same time, these explorations give students control over, and responsibility for, their own learning - a powerful pedagogical approach. Student control over their learning is also the goal of an initiative to use scanning technologies, such as linear bar codes, 2D barcodes and radio-frequency identification (RFID), to revolutionize sample identification and study. Scanning technology allows students to

    Understanding quality of life and participation is a key aspect of occupational therapy research. The use of smartphones to deliver experience-sampling surveys may provide an accessible way to monitor these outcomes. This study used smartphone-based experience sampling methods (ESM) to investigate factors influencing momentary quality of life (mQOL) of university students. A convenience sample of students at an Australian university participated. Using a custom smartphone application, ESM surveys were sent six to eight times, every second day, over a week. Participants indicated their mQOL, occupational participation, occupational enjoyment, social context and location via surveys and provided demographic and health information in a single self-report questionnaire. The relationship between mQOL and variables was analysed at the survey level using logistic regression. Forty students completed 391 surveys. Higher mQOL was significantly related to participation in productive occupations (z = 3.48; P = 0.001), moderate (z = 4.00; P sample, analysing at the individual level, and using ESM in conjunction with other methodologies is recommended. © 2017 Occupational Therapy Australia.

    Full Text Available Abstract Background Despite a growing body of research from the United States and other industrialized countries on the inverse association between supportive social relationships in the school and youth risk behavior engagement, research on the measurement of supportive school social relationships in Central America is limited. We examined the psychometric properties of the Student Perceptions of School Cohesion (SPSC scale, a 10-item scale that asks students to rate with a 5-point Likert-type response scale their perceptions of the school social environment, in a sample of public secondary school students (mean age = 15 years living in central El Salvador. Methods Students (n = 982 completed a self-administered questionnaire that included the SPSC scale along with measures of youth health risk behaviors based on the Center for Disease Control and Prevention's Youth Risk Behavior Survey. Exploratory factor analysis was used to assess the factor structure of the scale, and two internal consistency estimates of reliability were computed. Construct validity was assessed by examining whether students who reported low school cohesion were significantly more likely to report physical fighting and illicit drug use. Results Results indicated that the SPSC scale has three latent factors, which explained 61.6% of the variance: supportive school relationships, student-school connectedness, and student-teacher connectedness. The full scale and three subscales had good internal consistency (rs = .87 and α = .84 for the full scale; rs and α between .71 and .75 for the three subscales. Significant associations were found between the full scale and all three subscales with physical fighting (p ≤ .001 and illicit drug use (p Conclusion Findings provide evidence of reliability and validity of the SPSC for the measurement of supportive school relationships in Latino adolescents living in El Salvador. These findings provide a foundation for further research on

    A factor analytic and a Rasch measurement approach were applied to evaluate the multidimensional nature of the school motivation construct among more than 7,000 Dutch secondary school students. The Inventory of School Motivation (McInerney and Ali, 2006) was used, which intends to measure four motivation dimensions (mastery, performance, social, and extrinsic motivation), each comprising of two first-order factors. One unidimensional model and three multidimensional models (4-factor, 8-factor, higher order) were fit to the data. Results of both approaches showed that the multidimensional models validly represented the school motivation among Dutch secondary school pupils, whereas model fit of the unidimensional model was poor. The differences in model fit between the three multidimensional models were small, although a different model was favoured by the two approaches. The need for improvement of some of the items and the need to increase measurement precision of several first-order factors are discussed.

    2017-04-01

    Previous research has shown a relationship between financial difficulties and poor mental health in students, but most research is cross-sectional. To examine longitudinal relationships over time between financial variables and mental health in students. A national sample of 454 first year British undergraduate students completed measures of mental health and financial variables at up to four time points across a year. Cross-sectional relationships were found between poorer mental health and female gender, having a disability and non-white ethnicity. Greater financial difficulties predicted greater depression and stress cross-sectionally, and also predicted poorer anxiety, global mental health and alcohol dependence over time. Depression worsened over time for those who had considered abandoning studies or not coming to university for financial reasons, and there were effects for how students viewed their student loan. Anxiety and alcohol dependence also predicted worsening financial situation suggesting a bi-directional relationship. Financial difficulties appear to lead to poor mental health in students with the possibility of a vicious cycle occurring.

    Full Text Available Objectives: This study was conducted to explore the barriers to physical activity in a representative sample of Iranian children and adolescents.Methods: The studywas conducted in 2007 in urban and rural areas of Isfahan district in Iran. In the qualitative part,we used the grounded theory approach, including semi-structured focus group discussionsand in-depth interviews. The quantitative part comprised 600 randomly selected students.Results: The qualitative study included 34 school students (16 girls, 20 parents (11 mothers and 11 school staff. All students disclosed that studying was a priority.They pointed to lack of safe and easy-access place for physical activity and unsupportive family as the main barriers. Lack of self-confidence and low self-worth were the two other concepts developed in this context.Parents pointed to lack of safe and easy-access place for activity followed by the priority of studying. The concepts derived from interviews with school staff included unhealthy modeling of parents, priority of studying, and inadequate public know-ledge about how to integrate physical activity in routine daily life.The quantitative survey comprised 600 students including 286 (47.8% girls. Parents’ education level had inverse association with children’s physical activity level. Significant inverse associations of self-efficacy and physical activity levels were documented.Conclusions: Increasing the public knowledge about adopting physical activity habits in routinedaily life, informing the families and students about the benefits of physical activity to improvelearning, as well as providing safe places such as using the school facilities in non-school hoursshould be considered in planning effective preventive strategies and interventions.

    The aim of this study is to analyze a set of socializing agents for sport and physical activities and to establish their relationship with leisure time sport and physical activities behaviors and practice patterns in samples of teenage students with different sociocultural backgrounds. The sample included 2168 students in their first year of secondary education, 423 of them being from Costa Rica, 408 from Mexico, and 1337 from Spain (1052 male students, 1037 female students, and 79 students who did not specify gender) aged 11-16 years old ( M = 12.49; SD = .81). A validated questionnaire with questions about leisure time sport and physical activities and socializing agents was used. Descriptive, inferential, and multinomial logistic regression analyses were carried out with SPSS 17.0 to compare all three countries. Costa Rica had the most active students, best friends' inactivity, and unsupportive parents being the agents predicting inactivity and a low level of sport and physical activities. Mexico has a high dropout rate and inactive students exceed active ones; no agent predicts inactivity or sport and physical activities pattern. Spain has the highest level of sport and physical activities practice, and parents, siblings, and friends are predicting agents of inactivity together with unsupportive parents and friends.

    Stella Regina Martins

    Full Text Available ABSTRACT Objective: To determine the level of agreement with effective tobacco control measures recommended by the World Health Organization and to assess the attitudes toward, knowledge of, and beliefs regarding smoking among third-year medical students at University of São Paulo School of Medicine, located in the city of São Paulo, Brazil. Methods: Between 2008 and 2012, all third-year medical students were invited to complete a self-administered questionnaire based on the Global Health Professionals Student Survey and its additional modules. Results: The study sample comprised 556 students. The level of agreement with the World Health Organization recommendations was high, except for the components “received smoking cessation training” and “raising taxes is effective to reduce the prevalence of smoking”. Most of the students reported that they agree with banning tobacco product sales to minors (95%, believe that physicians are role models to their patients (84%, and believe that they should advise their patients to quit cigarette smoking (96% and using other tobacco products (94%. Regarding smoking cessation methods, most of the students were found to know more about nicotine replacement therapy than about non-nicotine therapies (93% vs. 53%. Only 37% of the respondents were aware of the importance of educational antismoking materials, and only 31% reported that they believe in the effectiveness of encouraging their patients, during medical visits. In our sample, the prevalence of current cigarette smoking was 5.23%; however, 43.82% of the respondents reported having experimented with water-pipe tobacco smoking. Conclusions: Our results revealed the need to emphasize to third-year medical students the importance of raising the prices of and taxes on tobacco products. We also need to make students aware of the dangers of experimenting with tobacco products other than cigarettes, particularly water-pipe tobacco smoking.

    Several studies have advocated a relationship between psychopathological features and sexual compulsivity. Such relationship is often found among individuals seeking help for out of control sexual behavior, suggesting that the association between psychological adjustment and sexual compulsivity may have a significant clinical value. However, a more complete approach to the topic of sexual compulsivity would also include the analysis of nonclinical samples as healthy individuals may be at risk of developing some features of hypersexuality in the future. The aim of this study was to explore the relationship between stable traits of personality, state psychopathology, and sexual compulsivity in a sample of male college students. Furthermore, the potential mediating role of state psychopathology in the relationship between personality traits and sexual compulsivity was tested. Participants completed the following measures: the NEO Five-Factor Inventory, the Brief Symptom Inventory, and the Compulsive Sexual Behavior Inventory-22. The sample included 152 male college students recruited in a Portuguese university using nonrandom methods. The measures were completed individually and anonymously. Findings on state psychopathology suggested that psychoticism may be one of the key dimensions associated with sexual compulsivity in male students. The personality traits of Neuroticism and Agreeableness were also significant predictors of sexual compulsivity. Findings on the mediating effects suggested that state psychopathology mediated the relationship between Neuroticism and sexual compulsivity but not between Agreeableness and sexual compulsivity. A psychopathological path (encompassing Neuroticism and state psychopathology) and a behavioral path (encompassing Agreeableness features) may be involved in sexual compulsivity as reported by a nonclinical sample of male students. © 2013 International Society for Sexual Medicine.

    Internet Addiction Disorder can be defined as "the inability of individuals to control their internet use, resulting in marked distress and/or functional impairment in daily life." It carries the same social aftermath of impulse control and substance misuse disorders such as loss of control, craving and withdrawal symptoms. In this paper, we aimed to assess the prevalence of IAD in an Italian sample of high-school students. We also explored the relationship between Social Phobia and IAD diagnosis; lastly, we investigated the association between IAD and substance misuse. The research was conducted in accordance with the Helsinki Declaration. Assessments administered in this study consisted of three parts: 1) collecting information about general and personal data of the subjects; 2) the Internet Addiction questionnaire proposed by Ko, composed by 9 different areas; 3) the Social Anxiety Spectrum Self-Report (SHY-SR) Lifetime Questionnaire. 19 of 402 subjects (i.e. 4.7% of the sample) fulfilled the diagnostic criteria for IAD, showing a slight predominance of males. 10.9% of subjects met diagnostic criteria for a Social Phobia Spectrum disorder. Six IAD subjects (31.8%) were also diagnosed with a social phobia spectrum condition. Within the group of students diagnosed with IAD, 4 (21.05%) subjects reported current or past use of drugs. Our results suggest that there is a sizable population of youth already showing or at risk of developing some kind of problematic relationship with the web. Social Anxiety Disorder seems to be both a risk factor and a frequent co-morbid disorder of internet misuse. Further studies along with shared diagnostic criteria and tools will facilitate research on treatments for these rapidly expanding and disabling conditions.

    2016-01-01

    Full Text Available In order to determine physical fitness differences in students with different cardiorespiratory endurance levels, a study was conducted on a sample of students of the Faculty of Sport and Physical Education at the University of Nis. The sample was divided into two subsamples, where the first subsample comprised 27 female students and the other 35 male students. Physical fitness was assessed using eight tests from the Eurofit battery of tests: the single-leg balance test - for the assessment of general balance, plate tapping - for the assessment of speed of movement, sit-and-reach - for the assessment of flexibility, the standing broad jump - for the assessment of explosive strength, the handgrip test - for the assessment of static strength, sit-ups - for the assessment of repetitive trunk strength, the bent arm hang - for the assessment of muscular endurance and the 10x5 meter shuttle run - for the assessment of the speed/agility. Cardiorespiratory endurance was estimated with the aid of 20 m endurance shuttle-run test. Based on the level of cardiorespiratory endurance, the participants in each subsample, were divided into three groups using a cluster analysis: high (VKRI, average (PKRI and low level (NKRI. The physical fitness differences of students with different cardiorespiratory endurance levels were calculated using the one-way analysis of variance. The results showed that there were no differences in physical fitness of students with different cardiorespiratory endurance levels. Based on the results it can be concluded that the level of cardiorespiratory endurance does not affect the components of physical fitness among students of both sexes.

    Al Khalaileh, Murad; Al Qadire, Mohammad

    Pain management requires knowledgeable and trained nurses. Because nursing students are the nurses of the future, it is important to ensure that students receive adequate education about pain management in nursing schools. The purpose of this study is to evaluate nursing students' knowledge and attitudes regarding pain management. A cross-sectional survey was used. The sample comprised 144 students from three nursing colleges in Jordan. Sixty-one percent were female and the average age was 21.6 years (SD 1.7). The students' Knowledge and Attitudes Survey Regarding Pain was used. The rate of correct answers ranged from 11.1% to 64%. Students showed a low level of knowledge regarding pain management-the average score was just 16 (SD 5.11) out of 40. Students were weak in their knowledge of pain medications pharmacology (actions and side effects). Less than half of students (47.9%) recognised that pain may be present, even when vital signs are normal and facial expressions relaxed. Finally, students showed negative attitudes towards pain management, believing that patients should tolerate pain as much as they can before receiving opioids; almost half (48%) of students agreed that patients' pain could be managed with placebo rather than medication. In conclusion, Jordanian nursing students showed lower levels of pain knowledge compared with other nursing students around the world. This study underlines the need to include pain-management courses throughout undergraduate nursing curricula in Jordan.

    2016-11-01

    This study examined the effects of teachers' biology-specific dimensions of professional knowledge - pedagogical content knowledge (PCK) and content knowledge (CK) - and cognitively activating biology instruction, as a feature of instructional quality, on students' learning. The sample comprised 39 German secondary school teachers whose lessons on the topic neurobiology were videotaped twice. Teachers' instruction was coded with regard to cognitive activation using a rating manual. Multilevel path analysis results showed a positive significant effect of cognitive activation on students' learning and an indirect effect of teachers' PCK on students' learning mediated through cognitive activation. These findings highlight the importance of PCK in preservice biology teachers' education.

    This study investigated the relationships among resilience, social anxiety, and procrastination in a sample of college students. Specifically, structural equation modeling analyses were applied to examine the effect of resilience on procrastination and to test the mediating effect of social anxiety. The results of this study suggested that social anxiety partially mediated the relationship between resilience and procrastination. Students with higher levels of resilience reported a lower frequency of procrastination behavior, and resilience had an indirect effect on procrastination through social anxiety. The results of this study clarify the current knowledge of the mixed results on resilience and procrastination behaviors and offer practical learning strategies and psychological interventions.

    Procrastination is a common behavior which affects different aspects of life. The procrastination assessment scale-student (PASS) evaluates academic procrastination apropos its frequency and reasons. The aims of the present study were to translate, culturally adapt, and validate the Farsi version of the PASS in a sample of Iranian medical students. In this cross-sectional study, the PASS was translated into Farsi through the forward-backward method, and its content validity was thereafter assessed by a panel of 10 experts. The Farsi version of the PASS was subsequently distributed among 423 medical students. The internal reliability of the PASS was assessed using Cronbach's alpha. An exploratory factor analysis (EFA) was conducted on 18 items and then 28 items of the scale to find new models. The construct validity of the scale was assessed using both EFA and confirmatory factor analysis. The predictive validity of the scale was evaluated by calculating the correlation between the academic procrastination scores and the students' average scores in the previous semester. The corresponding reliability of the first and second parts of the scale was 0.781 and 0.861. An EFA on 18 items of the scale found 4 factors which jointly explained 53.2% of variances: The model was marginally acceptable (root mean square error of approximation [RMSEA] =0.098, standardized root mean square residual [SRMR] =0.076, χ(2) /df =4.8, comparative fit index [CFI] =0.83). An EFA on 28 items of the scale found 4 factors which altogether explained 42.62% of variances: The model was acceptable (RMSEA =0.07, SRMR =0.07, χ(2)/df =2.8, incremental fit index =0.90, CFI =0.90). There was a negative correlation between the procrastination scores and the students' average scores (r = -0.131, P =0.02). The Farsi version of the PASS is a valid and reliable tool to measure academic procrastination in Iranian undergraduate medical students.

    Theories of restorative justice suggest that the practice works best when offenders are enmeshed in multiple interdependencies or attachments to others and belong to a culture that facilitates communitarianism instead of individualism. Restorative justice principles and practices are thus believed to be incongruent with the individualistic culture and legal system of the United States, especially compared with that of nations like Australia and Japan. Using a nonprobability convenience sample of students enrolled in a large public university in the United States, our study examines attitudes toward restorative justice as a fair and just process for reintegrating offenders and meeting the needs of victims. Results indicate that our sample holds less punitive attitudes than citizens in either Australia or Japan. Our findings are discussed in light of recent policy shifts in the United States that suggest a concerted move toward decarceration following the 2008 recession.

    The aim of this study was to compare the perceived competence for treating prosthodontic patients of two samples of fourth-year dental students: those educated using traditional methodologies and those educated using problem-based learning (PBL). Two cohorts of fourth-year dental students at a dental school in Spain were surveyed: the traditional methods cohort (n=46) was comprised of all students in academic years 2012 and 2013, and the PBL cohort (n=57) was comprised of all students in academic years 2014 and 2015. Students in both cohorts reported the number of prosthodontic treatments they carried out per year and their perceived level of competence in performing such treatments. The results showed that the average number of treatments performed was similar for the two cohorts, except the number of metal-based removable partial dentures was significantly higher for students in the traditional (0.8±1.0) than the PBL (0.4±0.6) cohort. The level of perceived competence to treat complete denture patients for the combined cohorts was significantly higher (7.3±1.1) than that for partial acrylic dentures (6.7±1.5) and combined dentures (5.7±1.3). Students' clinical competence in prosthodontics mainly depended on number of treatments performed as the operator as well as the assistant. Students in the traditional methods cohort considered themselves to be significantly more competent at treating patients for removable partial and fixed prostheses (7.8±1.1 and 7.6±1.1, respectively) than did students in the PBL cohort (6.4±1.5 and 6.6±1.5, respectively). Overall, however, the study found that practical experiences were more important than the teaching method used to achieve students' perceived competence.

    An improved nanophosphor composite comprises surface modified nanophosphor particles in a solid matrix. The nanophosphor particle surface is modified with an organic ligand, or by covalently bonding a polymeric or polymeric precursor material. The surface modified nanophosphor particle is essentially charge neutral, thereby preventing agglomeration of the nanophosphor particles during formation of the composite material. The improved nanophosphor composite may be used in any conventional scintillator application, including in a radiation detector.

  6. A curricular frame for physics education: Development, comparison with students' interests, and impact on students' achievement and self-concept

    2000-11-01

    This article presents three interlinked studies aimed at: (1) developing a curricular frame for physics education; (2) assessing the students' interest in the contents, contexts, and activities that are suggested by that curricular frame; and (3) developing a curriculum that is in line with that frame and measuring its cognitive and emotional effects on students. The curricular frame was developed by adopting the Delphi technique and drawing on the expertise of 73 persons selected according to specified selection criteria. Interest data of some 8000 students and information of the presently taught physics curriculum were sampled longitudinally as well as cross-sectionally in various German Länder (states) by questionnaire. The third study comprised 23 experimental and 7 control classes. As a result of the comparison between the features of the curricular frame, the interest structure of students, and the current physics curriculum, there is a remarkable congruency between students' interest in physics and the kind of physics education identified in the Delphi study as being relevant. However, there is a considerable discrepancy between students' interest and the kind of physics instruction practiced in the physics classroom. Regression analysis revealed that students' interest in physics as a school subject is hardly related to their interest in physics, but mainly to the students' self-esteem of being good achievers. The data strongly suggest physics be taught so that students have a chance to develop a positive physics-related self-concept and to link physics with situations they encounter outside the classroom. A curriculum based on these principles proved superior compared to a traditional curriculum.

    To find out the frequency and contents of online social networking (Facebook) among medical students of Dow University of Health Sciences. The sample of the study comprised of final year students of two medical colleges of Dow University of Health Sciences - Karachi. Systematic search for the face book profiles of the students was carried out with a new Facebook account. In the initial phase of search, it was determined whether each student had a Facebook account and the status of account as ''private'' ''intermediate'' or ''public'' was also sought. In the second phase of the study, objective information including gender, education, personal views, likes, tag pictures etc. were recorded for the publicly available accounts. An in depth qualitative content analysis of the public profiles of ten medical students, selected randomly with the help of random number generator technique was conducted. Social networking with Facebook is common among medical students with 66.9% having an account out of a total 535 students. One fifth of profiles 18.9% were publicly open, 36.6% profiles were private and 56.9% were identified to have an intermediate privacy setting, having customized settings for the profile information. In-depth analysis of some public profiles showed that potentially unprofessional material mostly related to violence and politics was posted by medical students. The usage of social network (Facebook) is very common among students of the university. Some unprofessional posts were also found on students' profiles mostly related to violence and politics.

    Achievement in math and achievement in verbal school subjects are more strongly correlated than the respective academic self-concepts. The internal/external frame of reference model (I/E model; Marsh, 1986, Am. Educ. Res. J., 23, 129) explains this finding by social and dimensional comparison processes. We investigated a key assumption of the model that dimensional comparisons mainly depend on the difference in achievement between subjects. We compared correlations between subject-specific self-concepts of groups of elementary and secondary school students with or without achievement differences in the respective subjects. The main goals were (1) to show that effects of dimensional comparisons depend to a large degree on the existence of achievement differences between subjects, (2) to demonstrate the generalizability of findings over different grade levels and self-concept scales, and (3) to test a rarely used correlation comparison approach (CCA) for the investigation of I/E model assumptions. We analysed eight German elementary and secondary school student samples (grades 3-8) from three independent studies (Ns 326-878). Correlations between math and German self-concepts of students with identical grades in the respective subjects were compared with the correlation of self-concepts of students having different grades using Fisher's Z test for independent samples. In all samples, correlations between math self-concept and German self-concept were higher for students having identical grades than for students having different grades. Differences in median correlations had small effect sizes for elementary school students and moderate effect sizes for secondary school students. Findings generalized over grades and indicated a developmental aspect in self-concept formation. The CCA complements investigations within I/E-research. © 2017 The British Psychological Society.

    Full Text Available The present study sought to investigate the probable link between Iranian English translation studies students’ metacognitive awareness, self-regulation, and gender. Furthermore, the role of educational level of translation students in metacognitive awareness and self-regulation was explored. For the purpose of the study, a sample of 230 M.A and B.A senior English translation students comprised the participants of the research. They were asked to complete two questionnaires of Metacognitive Awareness Inventory (MAI and Self-regulation Trait (SRT.The Metacognitive Awareness Inventory (MAI was developed by Schraw and Dennison (1994 and consists of 52 statements. It measures two components of metacognition: metacognitive knowledge and metacognitive regulation. Metacognitive knowledge comprises three subscales: Declarative knowledge, Procedural knowledge, and Conditional knowledge. Metacognitive regulation consists of five subscales: Planning, Information management, Monitoring, Debugging, and Evaluation. The self-regulation trait (SRT questionnaire was designed by O'Neil and Herl (1998. It was developed based on Zimmerman's self –regulation model. It consists of 32 Likert-scale questions. The scale seeks to measure metacognition and motivation dimensions.  Each dimension comprises two sub-scales. Meta-cognition covers the constructs of planning and self-monitoring, and motivation contains effort and self-efficacy. Independent samples t-tests were run to investigate the role of gender and educational level in the level of translation students’ metacognitive awareness and self-regulation. The results of t-test demonstrated that there are not any differences between male and female translation students regarding metacognitive awareness and self-regulation. It was also found that there is a negative significant impact of educational level on total metacognitive awareness, and some components of metacognitive awareness: declarative knowledge

    This study was designed to ascertain teachers' perceptions of bullying of Lesbian, Gay, Bisexual, Transgender, and Questioning (LGBTQ) youth. In a sample of 200 educators (61.0% female; 96.5% White) from a county in southwestern Pennsylvania, there was a significant positive relationship between the teachers' perceptions of the supportiveness of school staff towards students regardless of sexual orientation and those teachers' reports of the frequency of bullying victimization experienced by LGBTQ students. Teachers' perceptions of a higher level of staff and student support was associated with higher reported frequencies of students' use of derogatory language about LGBTQ individuals and various types of bullying of LGBTQ students. Teachers with a lesbian, gay, or bisexual orientation were found to rate the school staff and students as significantly less supportive of students regardless of their sexual orientation, gender identity, or gender expression in comparison to heterosexual teachers. Finally, teachers who either were unaware of or believed that their school lacked an anti-bullying policy reported significantly higher rates of physical bullying victimization of LGBTQ students when compared to the rates observed by teachers who reported knowledge of their schools' anti-bullying policies.

    2018-04-01

    There is a lack of empirically supported theories explaining suicidal ideation and few theories describe how suicidal ideation can be prevented in the context of normative human development. Rogers (2001) proposed an existential constructivist theory of suicide (ECTS) wherein existential distress and the inability to reconstruct meaning from adverse life events contribute to suicidal ideation. The ECTS includes a distinct focus on meaning reconstruction from adverse life events, which is congruent with existing research on college students and developmental frameworks used by counseling psychologists. Thus, in the present study, we tested the predictions of the ECTS in a college student sample. We collected data online from 195 college students (i.e., ages 18-25) attending a large, Midwestern university and analyzed the data using structural equation modeling. Findings provided partial support for the original ECTS. Post hoc analyses of an alternate ECTS model indicated that existential distress mediated the negative association between meaning reconstruction and suicidal ideation.

    The purpose of this study was to examine the prevalence of smoking in a nationally representative sample of Chinese elementary and middle school students and to investigate its risk factors from families and schools. The data were from the National Children's Study of China (NCSC), in which 24,013 fourth- to ninth-grade students were recruited from 100 counties in 31 provinces in China. Chi-square tests and one-way ANOVAs were used to analyze the relationships between smoking and the risk factors. Logistic regressions were used to calculate odds ratios. The prevalence of ever smokers and current smokers were 19.0% and 5.4%. Focusing on current smokers, boys, middle school students, rural students, boarding students, non-only children and those owning parents with low educational levels reported smoking significantly more than girls, elementary school students, urban students, non-boarding students, only children and those owning parents with high educational levels. Lower trust and support from teachers and higher parent-child conflict positively predicted both smoking and smoking frequency. Lower trust and support from classmates was associated with higher possibility of smoking. However, higher trust and support from classmates was associated with higher smoking frequency. Teacher smoking and friend smoking were only predictive of smoking, but not of smoking frequency. Boys, middle school students, rural students, boarding students, non-only children and those owning parents with low educational levels need special attention. The most risk factors for smoking and smoking frequency were lower trust and support from teachers and higher parent-child conflict. Copyright © 2014 Elsevier Ltd. All rights reserved.

    This study aimed to investigate and compare the executive functions of students with depression, anxiety, and stress symptoms with those functions in healthy ones. This study was a comparative and non-clinical analysis. The study population comprised all students of Shahid Beheshti University, Tehran, Iran. A total of 448 students were recruited using convenience sampling method. They were also screened using the Depression Anxiety Stress Scales (DASS) test comprising 21 items. Of study participants, 30 people were depressed, 27 had anxiety, and 15 suffered from stress. Then, 50 control people were matched with them. Next, both groups were compared using the Stroop test, Wisconsin card sorting, and cognitive ability test. Using MANOVA test, data analysis revealed no significant differences among 4 groups with regard to selective attention and shifting attention. Depressed group reacted rapidly as opposed to the anxiety group with regard to measures of shifting attention and cognitive abilities; it was observed that the memory, inhibition control, planning, and flexibility of the healthy group were better than those of the 3 other groups. The findings of this research raised specific issues in relation to the role of depression, anxiety, and stress in the disruption of the executive functions of sufferers. Selective and shifting attention and cognitive abilities are specifically affected in this regard. Meanwhile, the role of stress in impairing decision making and the major role of anxiety in impairing sustained attention was shown to be considerable.

    A novel thermal source comprising a semiconductor hyperbolic metamaterial provides control of the emission spectrum and the angular emission pattern. These properties arise because of epsilon-near-zero conditions in the semiconductor hyperbolic metamaterial. In particular, the thermal emission is dominated by the epsilon-near-zero effect in the doped quantum wells composing the semiconductor hyperbolic metamaterial. Furthermore, different properties are observed for s and p polarizations, following the characteristics of the strong anisotropy of hyperbolic metamaterials.

  1. Finessing incivility: The professional socialisation experiences of student nurses' first clinical placement, a grounded theory.

    Clinical practice is where student nurses are socialised into a professional role and acquire the distinct behaviour, attitudes and values of the nursing profession. Getting it right at the outset can maximise the development of a professional identity and the transmission of robust value systems. To explore the impact of the first clinical placement on the professional socialisation of adult undergraduate student nurses in the United Kingdom. Data of a longitudinal qualitative nature were collected and analysed using grounded theory. First year student nurses in hospital ward placements comprising a rural District General Hospital and a large inner city Hospital kept daily unstructured diaries for six weeks. A total of 26 undergraduate adult student nurses were purposefully sampled between 2008 and 2010 before undertaking their initial clinical placement. Data collection and analysis used grounded theory and the key question asked of the diarists 'tell me what it is like to be a first year nurse on a first placement' was theoretically adjusted during constant comparison and as the theory emerged. Ethical approval and consent was obtained. The theory of finessing incivility comprises a conceptual framework depicting how student nurses deal with professional incivility during their initial clinical placement and sustain a student identity. Being disillusioned with their role as worker rather than learner yields a sense of 'status dislocation'. Despite needing professional benevolence, they remain altruistic and seek recompense from significant others to negotiate for learning opportunities and relocate their student status. Despite the stressful transition into clinical practice rather than 'fit in', the student nurses want to belong as learners. His or her own resilience to learn nursing and be a professional student maintains their resolve, their altruism and strengthens their existing values to be benevolent towards an indifferent profession.

    To investigate the effectiveness, related knowledge, attitudes, and practices of hand hygiene (HH) among dental students with different levels of clinical experience. This was a cross-sectional analytical study. Bacterial samples on the participants' hands were obtained using a swab technique before and after handwashing, for oral surgical procedures. After culturing, the colony-forming units were counted. Self-reported questionnaires reflecting the knowledge, attitudes, and practices related to HH were completed by the participants. This study was performed in a primary oral health care institution, Faculty of Dentistry, Chulalongkorn University (Bangkok, Thailand). Bacterial samples and self-reported questionnaires were collected in the Department of Oral and Maxillofacial Surgery. Bacterial culture was performed in the Department of Microbiology. The 120 participants comprised first, second, third-year clinical training students (CTs), and postgraduate dental students (PGs) (32, 34, 30, and 24 participants, respectively). More than 99% of the bacteria were eliminated from the participants' hands after handwashing. Significantly higher numbers of bacteria were recovered from the hands of the PGs compared with those of the CTs, and the hands of the third-year CTs compared with those of the first-year CTs (p < 0.001), after HH. The first-year CTs had the highest attitude scores, whereas the PGs had the lowest practice scores. The knowledge scores were similar in all groups. HH effectiveness, attitudes, and practices of dental students decreased as students gained more clinical experience, whereas knowledge did not. Our results suggest that HH instruction should be given throughout the duration of dental students' education. Copyright © 2016 Association of Program Directors in Surgery. Published by Elsevier Inc.

    The Academic Motivation Scale is one of the most frequently used instruments to assess academic motivation. It relies on the self-determination theory of human motivation. However, motivation has been understudied in dental education. Therefore, to address the lack of valid instruments to assess academic motivation in dental education and contribute to future research in the field, the aim of this study was to analyze the psychometric properties of this instrument in a sample of dental students. Participants were 989 Chilean undergraduate dental students (86% response rate) who completed a survey containing a Chilean face-valid version of the Spanish Academic Motivation Scale and three other motivation-related instruments to assess the survey's construct and criterion validity. Later, 76 of the students (out of 100 invited) took the survey again to assess its test-retest stability. The instrument's construct validity was supported by the superior goodness of fit of the seven-subscale Academic Motivation Scale over competing models through confirmatory factor analysis and by the expected correlations among its subscales. The concurrent criterion validity was supported by the confirmation of correlations between its subscales and external criteria. Adequate internal consistency and test-retest correlations were also found. The evidence from this study suggests that the Academic Motivation Scale is a preliminarily valid and reliable instrument to assess motivation in the predoctoral dental context. Future research in this area is needed to confirm or refute these results.

    2003-02-01

    Student views on the nature of science are shaped by a variety of out-of-school forces and television-mediated science is a significant force. To attempt to achieve a science for all, we need to recognize and understand the diverse messages about science that students access and think about on a regular basis. In this work I examine how high school students think about science that is mediated by four different program genres on television: documentary, magazine-format programming, network news, and dramatic or fictional programming. The following categories of findings are discussed: the ethics and validity of science, final form science, science as portrayed by its practitioners, and school science and television science. Student perceptions of the nature of science depicted on the program sample used in this study ranged from seeing science as comprising tentative knowledge claims to seeing science as a fixed body of facts.

    To analyze reliability of a self-applied questionnaire on substance use and misuse among adolescent students. Two cross-sectional studies were carried out for the instrument test-retest. The sample comprised male and female students aged 1119 years from public and private schools (elementary, middle, and high school students) in the city of Salvador, Northeastern Brazil, in 2006. A total of 591 questionnaires were applied in the test and 467 in the retest. Descriptive statistics, the Kappa index, Cronbach's alpha and intraclass correlation were estimated. The prevalence of substance use/misuse was similar in both test and retest. Sociodemographic variables showed a "moderate" to "almost perfect" agreement for the Kappa index, and a "satisfactory" (>0.75) consistency for Cronbach's alpha and intraclass correlation. The age which psychoactive substances (tobacco, alcohol, and cannabis) were first used and chronological age were similar in both studies. Test-retest reliability was found to be a good indicator of students' age of initiation and their patterns of substance use. The questionnaire reliability was found to be satisfactory in the population studied.

    Full Text Available Background: Sociability and shyness are orthogonal personality traits, wherein both are characterized by varying behavioral and psychophysiological correlates. Shyness should not be equated with the lack of sociability, as shyness relates to discomfort that occurs in the presence of others and sociability is identified with an individual's preference for being with others rather than alone. Objectives: The objective of this study was to examine the effect of type of schooling on sociability and shyness among students and to study the gender differences between sociability and shyness among students. Methodology: The sample comprised 210 students from both private and government schools situated in Delhi. Data were collected using Eysenck Personality Profiler for measuring sociability and Revised Cheek and Buss Shyness Scale. Results and Conclusion: The results obtained from ANOVA revealed that government school students were observed to be more sociable as compared to private school students. On the other hand, private school students were found to be more shy as compared to government school students. Females were observed to be more shy as compared to males. In addition, significant interactive effect was observed for sociability when school and gender were taken altogether.

    Full Text Available This study was designed to ascertain teachers’ perceptions of bullying of Lesbian, Gay, Bisexual, Transgender, and Questioning (LGBTQ youth. In a sample of 200 educators (61.0% female; 96.5% White from a county in southwestern Pennsylvania, there was a significant positive relationship between the teachers’ perceptions of the supportiveness of school staff towards students regardless of sexual orientation and those teachers’ reports of the frequency of bullying victimization experienced by LGBTQ students. Teachers’ perceptions of a higher level of staff and student support was associated with higher reported frequencies of students’ use of derogatory language about LGBTQ individuals and various types of bullying of LGBTQ students. Teachers with a lesbian, gay, or bisexual orientation were found to rate the school staff and students as significantly less supportive of students regardless of their sexual orientation, gender identity, or gender expression in comparison to heterosexual teachers. Finally, teachers who either were unaware of or believed that their school lacked an anti-bullying policy reported significantly higher rates of physical bullying victimization of LGBTQ students when compared to the rates observed by teachers who reported knowledge of their schools’ anti-bullying policies.

    Description of students' opinions about schizophrenia and depression. The study was carried out on a sample of 445 secondary school students, randomly allocated to a "schizophrenia" or a "depression" group (N = 221 and N = 224, respectively). Each respondent was asked to read a case-vignette describing a case of schizophrenia or depression, and then to fill the Questionnaire on the Opinions about Mental Illness--General Population's version (QO-GP). 35% of students in "schizophrenia" group vs. 85% in "depression" group attributed a correct diagnosis to case-vignette. 19% of students in the "schizophrenia" group vs. 39% in the "depression" group believed that these mental disorders can recover. Affective and civil rights were more frequently acknowledged to patients with depression than to those with schizophrenia. In both groups, the majority of students stated that mentally ill patients were unpredictable and socially dangerous. Students who reported TV stories on people with mentally ill were more frequently convinced on their unpredictability and social dangerousness. These results outline the need to: a) plan educational campaigns for students on mental disorders; b) alert media professionals on the impact that the way they present crimes committed by mentally ill patients may have on general population.

    The aim of the current study was to investigate the contributions of sad childhood experiences, depression, anxiety, and stress, existence of a sense of meaning, and pursuit of meaning in explaining life satisfaction of young adults in Turkey. The sample comprised 400 undergraduate students ( M age = 20.2 yr.) selected via random cluster sampling. There were no statistically significant differences between men and women in terms of their scores on depression, existence of meaning, pursuit of meaning, and life satisfaction scores. However, there were statistically significant differences between men and women on the sad childhood experiences, anxiety and stress. In heirarchical regression analysis, the model as a whole was significant. Depression and existence of meaning in life made unique significant contributions to the variance in satisfaction in life. Students with lower depression and with a sense of meaning in life tended to be more satisfied with life.

    Parenting styles have always been a crucial factor in influencing all aspects of a person's development. The purpose of this study is to test the structural equation model of academic achievement among the students using parenting styles as a moderator. The sample comprised 493 students from eight schools. Parenting styles are determined using the Parental Authority Questionnaire (Buri in J Pers Assess 57:110-119, 1991). Academic achievement is measured based on the students' performance in the Lower Secondary Assessment. Data were analyzed using structural equation modelling. Results demonstrated that model of authoritative and model of authoritarian fit the data of this study well. Both authoritative and authoritarian parenting styles are the most common practice of the parents. Parenting styles have been found to be a moderator of this study. The results indicated that parenting styles moderated the effect of academic self-concept on academic achievement. The impact of academic self-concept on academic achievement is found to be greater for the authoritative than the authoritarian parenting style.

    The aim of the study was to explore social anxiety spectrum gender differences, in a sample of university students. Overall, 823 University of Pisa students were assessed by Social Anxiety Spectrum Self-Report Questionnaire (SHYSR). Using a total score of 68 as the optimal diagnostic threshold, we classified students into two groups with levels of severity: low scorers (60%), significant gender differences emerged for 6 items: females reported higher rates of items related to “Performance fears”, that seemed to confirm the new DSM-5 specifier named “Performance only”, while males reported higher rate in a single item related to “Behavioural inhibition”. Females showed a significant higher total score and “Specific anxieties and phobic features” and “Interpersonal sensitivity” domain scores compared to males, in low severity subgroup, and males showed significant higher “Social phobic traits during childhood and adolescence” and “Behavioural inhibition and somatic symptoms” domain scores compared to females in the high severity subgroup. Finally, rate of individuals declaring to consume alcohol was significantly higher in males than females. Among university students, social anxiety spectrum seems to be more frequent in females than males. In males, social anxiety spectrum is more frequently associated with an early onset, behavioural inhibition and somatic symptoms and, consequently, with higher severity.

    Professional values are abstract and general behavioral principles that provide basic standards to judge aims and actions, and these principles are formed by strong emotional loyalty of members of the profession. Research was conducted to compare the career choice and professional values of nursing students at two universities in the upper Midwest of the United States and in the middle of Turkey. A descriptive and comparative design was used. The participants of the study were comprised nursing students from a university in the upper Midwest of United States and a university in the middle of Turkey. The sample consisted of 728 students in all grades. Data were collected by a questionnaire, The Nurses Professional Values Scale-Revised and Vocational Choices in Entering Nursing Scale. Number, percentage distribution, mean, standard deviation, t test, and one-way variance analysis were used in the analysis of data. Ethical considerations: Ethical approval was obtained from the Ethics Commission. Informed consent was received from the students. The students' mean age for American students was 24.3 ± 5.6 years, while the mean age for Turkish students was 19.8 ± 1.7 years. Mean score of American students on The Vocational Congruency (a subgroup of the Vocational Choices in Entering Nursing Scale) was 38.5 ± 5.9 and Turkish students was 29.6 ± 8.9 (p Values Scale-Revised was 109.2 ± 12.3 and that of Turkish students was 101.6 ± 17.0. This study concluded that the majority of nursing students had high professional values, and when students' scores were compared, American students had higher professional values, and in career choice, they considered primarily fitness of the profession to themselves and their goals, while Turkish students primarily thought of their living conditions.

    Full Text Available In this study we examined construct validity and reliability of the Academic Motivation Scale, College Version (Academic Motivation Scale, AMS-C 28, Vallerand et al., 1992 and its relationship with gender, certainty of study choice and career goals in Slovenian university students. The theoretical basis of AMS is derived from Self-Determination Theory, which identified different types of motivation on a continuum from amotivation to different types of external motivation and intrinsic (self-determined motivation. The AMS measures multidimensional motivational construct and contains seven scales. The validation sample consisted of 324 students of various studies at the University of Ljubljana. Multigroup confirmatory factor analysis showed an acceptable fit of the original 7-factor structure on Slovenian data and measurement invariance across gender. The highest were correlations among the three factors of intrinsic motivation and among the three factors of external motivation. Current certainty of study choice was positively associated with all three factors of intrinsic motivation and identified regulation, and negatively correlated with amotivation. Extrinsic career goals had low to moderate positive correlations with factors of external motivation while intrinsic career goals correlated positively with the three factors of intrinsic motivation, identified and introjected regulation, and negatively with amotivation. Female students had higher scores on intrinsic motivation to accomplish, and identified and introjected regulation than male students. In sum, the AMS C-28 showed good construct and convergent validity and reliability in Slovenian university context.

    The aim of this study was to qualitatively evaluate the experiences of students enrolled in the last year of dentistry school with ergonomic practice. This is a qualitative, observational and cross-sectional study, with a non-probabilistic sample design. The sample comprised students enrolled in the last year of dentistry in Araraquara-UNESP (n = 29). The data were collected by means of open semi-structured and individual interviews, captured by a digital voice recorder. The students were interviewed in their own university at a time that was previously scheduled, and care was taken to provide a private and welcoming environment to carry out the interviews. A script containing questions related to practices in ergonomics was prepared at the university. Data analysis was carried out using the qualitative-quantitative Collective Subject Discourse technique with the aid of Qualiquantisoft ® software program. It was found that more than half of the students (58.6%) believe that adopting an ergonomic posture is important to prevent future problems, pain and occupational diseases, and 62.1% of the students confirm having difficulties in adopting ergonomic postures due to the types of treatment required and the regions of the mouth being treated. The main reasons stated for the fact that their colleagues do not adopt ergonomic postures are lack of attention, practice and forgetfulness (44.8%) and difficulty in visualising the operatory field or the procedure performed (27.6%). It is possible to conclude that the students interviewed know ergonomic principles and their importance in occupational health. However, they found it difficult to put these principles into practice. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Many aspects of medical school are stressful for students. To empirically assess student reactions to clerkship programs, or to assess efforts to improve such programs, educators must measure the overall well-being of the students reliably and validly. The purpose of the study was to develop and validate a measure designed to achieve these goals. The authors developed a measure of quality of life for medical students by sampling (public domain) items tapping general happiness, fatigue, and anxiety. A quality-of-life scale was developed by factor analyzing responses to the items from students in two different clerkships from 2005 to 2008. Reliability was assessed using Cronbach's alpha. Validity was assessed by factor analysis, convergence with additional theoretically relevant scales, and sensitivity to change over time. The refined nine-item measure is a Likert scaled survey of quality-of-life items comprised of two domains: exhaustion and general happiness. The resulting scale demonstrated good reliability and factorial validity at two time points for each of the two samples. The quality-of-life measure also correlated with measures of depression and the amount of sleep reported during the clerkships. The quality-of-life measure appeared more sensitive to changes over time than did the depression measure. The measure is short and can be easily administered in a survey. The scale appears useful for program evaluation and more generally as an outcome variable in medical educational research.

    2017-07-01

    This study is aimed at exploring ninth-grade Bhutanese students' views of nature of science (NOS). A total of 389 students from middle secondary and higher secondary schools from the eastern, western, southern and central regions of Bhutan took part in this study. To generate a representative population, a stratified random sampling technique was used. An adopted and adapted version of the Students Understanding of Science and Scientific Inquiry (SUSSI) comprised Likert-type items, and open-ended questions were used as a research tool. Quantitative data were analysed using descriptive statistics, and the qualitative data were analysed and categorized into naïve, transitional and informed views. The results indicated that the majority of the Bhutanese students held naïve views on sociocultural embeddedness, scientific laws, scientific theories and science as a body of knowledge. The study has an implication for curriculum developers and teaching professionals, particularly in culturally rich countries, that explicit instruction of NOS should be reframed based on students' cultural backgrounds and their indigenous knowledge.

Data was collected via an original questionnaire and the Test Anxiety Inventory. SPSS 20 was used for statistical analyses. Of the 1250 students who qualified for the study, the final sample size was 376 (30%). Of them, 210 (55.9%) were females, and 154 (41%) were 18 years old. Students' mean Test Anxiety Inventory scores were 39.44±11.34. Female students' overall test anxiety scores and mean emotionality subscale score were significantly higher than those of their male counterparts. Students whose mothers had an educational attainment between primary school n=170 (45.2%) and a high school diploma n=184 (48.9%), as well as those with four or more siblings n=49 (15%), had significantly higher mean overall Test Anxiety Inventory scores. Among other things, test anxiety is influenced by maternal educational level, type of high school, number of exams, and number of siblings. Preparing a relaxed study environment for students, providing the family monetary or social support, and encouraging participation in social activities are recommendedto decreajb anxiety in students preparing for university exams.

    Tobacco use is the leading preventable cause of death worldwide. Besides cigarette smoking, waterpipe and e-cigarettes are gaining popularity among young adults. Medical students' smoking behavior is of particular interest because of their impending role in health promotion as future physicians. Aim of our study is to examine the prevalence and predictors of cigarette, waterpipe and e-cigarette use and the association of tobacco use with self-reported health status in an international sample of medical students. In a multicenter cross-sectional study data on different aspects of health behavior were collected from medical students of 65 nationalities using a self-administered questionnaire in Germany (Dresden, Munich) and Hungary (Budapest, Pécs). The survey was conducted among 1st, 3rd and 5th year students. To explore associations between smoking behavior and socio-cultural factors Pearson's chi 2 -tests and multivariate binary logistic regression analyses were performed. The largest subpopulations were formed by German (n = 1289), Hungarian (n = 1055) and Norwegian (n = 147) students. Mean age was 22.5 ± 3.3 years. Females represented 61.6% of the sample. In the whole sample prevalence of cigarette smoking was 18.0% (95% CI 16.6-19.4%), prevalence of waterpipe use was 4.8% (95% CI 4.0-5.7%), that of e-cigarette 0.9% (95% CI 0.5-1.2%). More males (22.0%) than females (15.5%) reported cigarette smoking. The lowest prevalence of cigarette smoking was found among Norwegian students (6.2%). Cigarette smokers were older, waterpipe users were younger than non-users. E-cigarette use was not associated with age of the students. Religious involvement was protective only against cigarette smoking. Financial situation showed no association with any kind of tobacco consumption. Cigarette smokers and e-cigarette users were less likely to report very good or excellent health status. Cigarette smoking is still the most popular way of consuming tobacco

    Full Text Available Abstract Background In medical education, feedback from students' is essential in course evaluation and development. Students at Faculty of Medicine, University of Colombo, Sri Lanka complete a five year medical curriculum comprising of five different streams. We aimed to evaluate the five year medical curriculum at the Faculty of Medicine, University of Colombo, Sri Lanka. Methods A qualitative research was conducted among recent graduates of the faculty. Students' opinions on strengths and weaknesses of the curriculum were collected via questionnaires, which were analysed and classified into common themes. A focus group discussion (FGD based on these themes was conducted among two student groups, each comprising of a facilitator, two observers and nine students selected as a representative sample from questionnaire respondents. FGDs were conducted using a semi-structured set of open-ended questions to guide participants and maintain consistency between groups. The FGD evaluated the reasons behind students' perceptions, attitudes, emotions and perceived solution. Verbal and non-verbal responses were transcribed and analysed. Results Questionnaire response rate was 82% (153/186. Students highlighted 68 and 135 different responses on strengths and weaknesses respectively. After analysis of both questionnaire and FGD results the following themes emerged: a well organized module system, increased frequency of assessments, a good variety in clinical appointments, lack of specific objectives and assessments at clinical appointments, community and behavioural sciences streams beneficial but too much time allocation, lengthy duration of course, inadequate knowledge provided on pharmacology and pathology. Conclusion We demonstrate how a brief qualitative method could be efficiently used to evaluate a curriculum spanning a considerable length of time. This method provided an insight into the students' attitudes and perceptions of the present faculty

    Maritza Espinoza Venegas

    Full Text Available This study aims to evaluate the psychometric properties of Collett-Lester's Fear of Death Scale. A sample of 349 nursing students answered Fear of Death and Attitude toward death scales. Content validity was checked by expert review; reliability was proven using Cronbach's alpha; statistical analysis of the items, correlation between items and construct validity were checked by the correlation of the Scale with the Attitude toward death Scale. The multidimensionality of the scale was reviewed through factor analysis with varimax rotation. The Fear of Death Scale possesses good internal consistency and construct validity, confirmed by the significant correlation with the Attitude toward death Scale. Factor analysis partially supports content validity of the subscale items, but presented a modified multidimensional structure that points towards the reconceptualization of the subscales in this sample.

    Full Text Available Culture is a form of creative expression of a human being through which he reshapes the world, acts on it adding it value and creating new, cultural values. A human being is able to create a product of culture only when he is free and able to express himself. A contemporary man can incorporate various cultural activities into his spare time. They are especially important when they concern children and young people: regardless of whether they are used in institutional settings or in spare time. The authors conducted an empirical research of students' assumptions and beliefs concerning cultural activities in their free time. The sample comprised 233 fifth grade students. The findings show that in their spare time fifth graders: engage in various cultural activities; that students who live in urban areas attend more cultural events; that students have the opportunity to engage in extra-curricular activities in the area of culture - join cultural and artistic groups and associations and engage in various creative pursuits at different levels of participation (as consumers, full participants; and that students' attitudes concerning the influence of parents and teachers on the selection of cultural activities to be pursued do not vary greatly by gender, location or school achievement. Cultural activities do play a significant part in the free time of primary school students. This is why it is important that guidance provided in school and in spare time should be brought in greaer harmony.

    In the past six decades, the Kuwaiti population has been exposed to rapid transformation in the quality of diet intake, daily activities, and career types. This major socioeconomic shift was accompanied by the introduction of both communicable and noncommunicable chronic diseases afflicting people of all ages. This article aims to detect a relationship between sociocultural characteristics-such as physical activity, dietary habits, and smoking-and the prevalence of metabolic syndrome (MetS). A descriptive, cross-sectional survey was conducted among 262 male university students in Kuwait; participants were selected by using a convenient nonrandom opportunistic sample. Associated social and health factors were obtained using a closed-ended questionnaire. BMI and blood tests that include clusters of MetS risk components were drawn from participants in primary health care clinics. More than half of the participants were overweight and obese; 74.4% of the participants reported they did not visit a nutritionist; 69.8% said that they are currently not on a diet; 53.4% of the students were nonsmokers; 42.7% reported moderate to very low daily physical activity. The prevalence of MetS components increased among students with older age, employed, and married ( p students needs to be considered by Kuwaiti community members and the government to highlight the risk factors of MetS on individuals' well-being, quality of life, and life expectation.

    WHAT IS KNOWN ON THE SUBJECT?: In general, the current studies of positive mental health use questionnaires or parts thereof. However, while these questionnaires evaluate aspects of positive mental health, they fail to measure the construct itself. WHAT DOES THIS PAPER ADD TO EXISTING KNOWLEDGE?: The widespread use and the lack of specific questionnaires for evaluating the positive mental health construct justify the need to measure the robustness of the Positive Mental Health Questionnaire. Also six factors are proposed to measure positive mental health. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: The availability of a good questionnaire to measure positive mental health in university students is useful not only to promote mental health but also to strengthen the curricula of future professionals. Introduction Nursing has a relevant role in managing mental health. It is important to identify and thereafter to enhance positive aspects of mental health among university nursing students. Aim The aim of the present study was to analyse the psychometric properties of the Positive Mental Health Questionnaire (PMHQ) in terms of reliability and validity using confirmatory factor analysis in a sample of university students. Method A cross-sectional study was carried out in a sample of 1091 students at 4 nursing schools in Catalonia, Spain. The reliability of the PMHQ was measured by means of Cronbach's alpha coefficient, and the test-retest stability was measured with the intraclass correlation coefficient (ICC). Confirmatory factor analysis was used to determine the validity of the factorial structure. Results Cronbach's alpha coefficient was satisfactory (>0.70) for four of the six subscales or dimensions and ranged from 0.54 to 0.79. ICC analysis was satisfactory for the six subscales or dimensions. The hypothesis was confirmed in the analysis of the correlations between subclasses and the overall scale, with the strongest correlations being found between the majority of

    Few measures are available to examine pornography use constructs, and this can compromise the reliability of statements regarding harmful use of pornography. This study aimed to confirm the factorial validity and internal consistency of the Pornography Consumption Inventory in a sample of male Brazilian university students. The inventory consists of a 4-factor, 15-item, 5-point Likert-type scale. After translation and back-translation of the inventory, it was administered to 100 male medical students. An initial model that included all 15 items of the inventory showed some substandard fit indices. Therefore, another model was tested, excluding an item that had loaded onto two different factors. Goodness-of-fit indices were better for the new model. Overall, findings from this study support using the inventory on Portuguese-speaking individuals. With additional replication across populations, other settings, and treatment-seeking patients, the Pornography Consumption Inventory could also potentially be shortened to 14 items.

    The aim of this study was to examine the validity and reliability of the Maslach Burnout Inventory-Human Services Survey (MBI-HSS) as a tool for assessing the prevalence and level of burnout in dental students in Spanish universities. The survey was adapted from English to Spanish. A sample of 533 dental students from 15 Spanish universities and a control group of 188 medical students self-administered the survey online, using the Google Drive service. The test-retest reliability or reproducibility showed an Intraclass Correlation Coefficient of 0.95. The internal consistency of the survey was 0.922. Testing the construct validity showed two components with an eigenvalue greater than 1.5, which explained 51.2% of the total variance. Factor I (36.6% of the variance) comprised the items that estimated emotional exhaustion and depersonalization. Factor II (14.6% of the variance) contained the items that estimated personal accomplishment. The cut-off point for the existence of burnout achieved a sensitivity of 92.2%, a specificity of 92.1%, and an area under the curve of 0.96. Comparison of the total dental students sample and the control group of medical students showed significantly higher burnout levels for the dental students (50.3% vs. 40.4%). In this study, the MBI-HSS was found to be viable, valid, and reliable for measuring burnout in dental students. Since the study also found that the dental students suffered from high levels of this syndrome, these results suggest the need for preventive burnout control programs.

    Orthorexia nervosa (ON) has been recently defined as a pathological approach to feeding related to healthiness concerns and purity of food and/or feeding habits. This condition recently showed an increasing prevalence particularly among young adults. In order to investigate the prevalence of ON and its relationship with gender and nutritional style among young adults, we explored a sample of students from the University of Pisa, Italy. Assessments included the ORTO-15 questionnaire and a socio-demographic and eating habits form. Subjects were dichotomized for eating habits (i.e. standard vs vegetarian/vegan diet), gender, parents' educational level, type of high school attended, BMI (low vs high vs normal BMI). Chi square tests were performed to compare rates of subjects with overthreshold ORTO-15 scores, and Student's unpaired t test to compare mean scores between groups. Two Classification tree analyses with CHAID growing method were employed to identify the variables best predicting ON and ORTO-15 total score. more than one-third of the sample showed ON symptoms (ORTO-15 ≥ 35), with higher rates among females. Tree analyses showed diet type to predict ON and ORTO-15 total score more than gender. Our results seem to corroborate recent data highlighting similarities between ON and anorexia nervosa (AN). We propose an interpretation of ON as a phenotype of AN in the broader context of Feeding and eating disorders (FEDs) spectrum.

    This paper reports a study, which explored the lived experiences of the essence in developing nursing students' professional competence. Nursing students experience a high level of stress due to unexpected, uncontrolled and uncertain aspects in the clinical learning environment. A purposeful sampling technique was used to select 18 participants from all second year students. Focus group interviews were conducted for collection of data. The data was analyzed by applying the Giorgi method of analyzing phenomenological data. Experience of responsibility is central to professional development. A secure relation with nurse consultants is the basis for learning. Students wish to see contexts and reach a holistic understanding. Continuous guidance as well as students' continuous supervision of patients is vital for understanding the larger context of care. Educators and professional nurses with supervision responsibility must display the knowledge and skills required to promote the development of nursing students' professional competence. This study also highlights the importance of the ethical dimension inherent in the concept of competence. Group supervision can offer an opportunity for students to address their experiences of their ability to deal with unfamiliar and existential demands of practice. These fundamental presuppositions comprise collective requirements for education and competence development in practice. Copyright 2009 Elsevier Ltd. All rights reserved.

    Full Text Available Background: Past research suggests that medical students experience high levels of psychological distress. Objective: The aim of the current study was to investigate the relationships among engagement in self-care behaviours, dispositional mindfulness, and psychological distress. Methods: The sample consisted of 139 female and 68 male Australian medical students (N=207 aged 17–41 years (M=21.82, SD=3.62 across the 5 years of the Monash University medical course. Participants completed an online survey comprising a demographics questionnaire, the Five Facet Mindfulness Questionnaire, the Health-Promoting Lifestyle Profile II, and the Depression, Anxiety, and Stress Scales. Results: Results revealed significant and interpretable multivariate correlations between distress and both mindfulness and self-care. Furthermore, the dispositional mindfulness observation subscale was found to be a significant moderator of the relationship between several dimensions of self-care and psychological distress. Conclusions: The present study points to the potential of self-care and mindfulness to decrease medical student distress and enhance well-being.

    The aim of this study was to evaluate the psychomotor skills of the dental students at University Complutense of Madrid (UCM), using a battery of psychometric tests. The sample comprised 306 students of the 1st, 2nd, 3rd and 4th years of Odontology, who, during the last month of the academic term, took the test on rotation of solid shapes, the Embedded Figures test in its group form (GEFT), the O'Connor Tweezer test, the MacQuarrie test for mechanical ability and the indirect vision test. Before these tests began, some personal data of all students were collected. The results showed some statistically significant correlation between several personal variables (sex, manual dominance and previous skills) and performance in the psychometric tests, although no significant relation was found between these variables and the students' academic qualifications. When comparisons were made between the psychomotor tests and the academic results of the students, significant differences appeared in the tracing and dotting subtests of the MacQuarrie test, whereby those students with higher practical qualifications reached the best punctuation. In the O'Connor Tweezer test, the students who obtained the worst results were those with lower qualifications. These data could serve to detect at an early stage those students who need greater educational support. No relation was found between the GEFT and the indirect vision test.

    Recent mathematics assessment findings indicate that Native American students tend to score below students of the ethnic majority. Findings suggest that students' beliefs about mathematics are significantly related to achievement outcomes. This study examined relations between self-beliefs and mathematics achievement for a national sample of 130 Grade 8 Native American students from the Trends in International Mathematics and Science Study (TIMSS) 2003 United States sample of (M age = 14.2 yr., SD = 0.5). Multiple regression indicated several significant relations of mathematics beliefs with achievement and accounted for 26.7% of the variance in test scores. Students who earned high test scores tended to hold more positive beliefs about their ability to learn mathematics quickly, while students who earned low scores expressed negative beliefs about their ability to learn new mathematics topics.

    There is a lack of up-to-date data on sleep and dream habits of college students. To fill in this gap, we used an online questionnaire sent to the student mailing lists of two major universities of Lyon (Lyon 1 and Lyon 2) for the recruitment of an functional magnetic resonance imaging study with sleep disorders as exclusion criteria. In the sample (1,137 French college students, 411 males, mean age = 22.2 ± 2.4 years, body mass index = 22.0 ± 3.2 kg m -2 ), on average, the participants reported spending about 8 hr in bed during weekdays, 9 hr during the weekends, and 90.9% of them reported no difficulty falling asleep. Less than 0.4% of students reported to have sleep-walking episodes regularly, but nearly 7% reported regular sleep-talking episodes. The average dream recall frequency was about 3 mornings per week with a dream in mind. Dream recall frequency was positively correlated with the clarity of dream content and the frequency of lucid dreaming, and was negatively correlated with age. Fourteen percent of the students reported frequent lucid dreams, and 6% reported frequent recurrent dreams. We found a gender effect for several sleep and dream parameters, including dream recall frequency and time in bed, both of which were higher in women than in men. We have also observed differences between academic disciplines, namely humanities students (Lyon 2) reported spending more time in bed than sciences students (Lyon 1). These results confirm a gender difference for several sleep and dream parameters, and suggest a link between academic disciplines and sleep duration. © 2018 European Sleep Research Society.

    The 30-item USDI is a self-report measure that assesses depressive symptoms among university students. It consists of three correlated three factors: lethargy, cognitive-emotional and academic motivation. The current research used confirmatory factor analysis to asses construct validity and determine whether the original factor structure would be replicated in a different sample. Psychometric properties were also examined. Participants were 1148 students (mean age 22.84 years, SD=6.85) across all faculties from a large Australian metropolitan university. Students completed a questionnaire comprising of the USDI, the depression anxiety stress scale (DASS) and Life Satisfaction Scale (LSS). The three correlated factor model was shown to be an acceptable fit to the data, indicating sound construct validity. Internal consistency of the scale was also demonstrated to be sound, with high Cronbach alpha values. Temporal stability of the scale was also shown to be strong through test-retest analysis. Finally, concurrent and discriminant validity was examined with correlations between the USDI and DASS subscales as well as the LSS, with sound results further supporting the construct validity of the scale. Cut-off points were also developed to aid total score interpretation. Response rates are unclear. In addition, the representativeness of the sample could be improved potentially through targeted recruitment (i.e. reviewing the online sample statistics during data collection, examining the representativeness trends and addressing particular faculties within the university that were underrepresented). The USDI provides a valid and reliable method of assessing depressive symptoms found among university students. © 2013 Elsevier B.V. All rights reserved.

    A number of methods to investigate growth have been reported in the literature, including hierarchical linear modelling (HLM), latent growth modelling (LGM), and multidimensional scaling applied to longitudinal profile analysis (LPAMS). This study aimed at modelling the mathematics growth of students over a span of 6 years from Grade 3 to Grade 9. The sample comprised secondary longitudinal data collected in three waves from n = 866 Hong Kong students when they were in Grade 3, Grade 6, and Grade 9. Mathematics achievement was measured thrice on a vertical scale linked with anchor items. Linear and nonlinear latent growth models were used to assess students' growth. Gender differences were also examined. A nonlinear latent growth curve with a decelerated rate had a good fit to the data. Initial achievement and growth rate were negatively correlated. No gender difference was found. Mathematics growth from Grade 6 to Grade 9 was slower than that from Grade 3 to Grade 6. Students with lower initial achievement improved at a faster rate than those who started at a higher level. Gender did not affect growth rate. © 2014 The British Psychological Society.

    Using a sample of Indonesian university students and a cross sectional design, this study investigated prevalence rates and patterns of pornography consumption in Indonesia, a religious, sexually conservative, Muslim-majority nation with strict anti-pornography laws. Further, the association between pornography consumption and common non-marital sexual behaviours was explored. The study found that in this sample, pornography is as widely and readily consumed as in comparable international studies predominantly utilising Western background samples from more sexually liberal and less religious countries with very few laws on pornography. Gender differences in patterns of pornography consumption were pronounced and comparable with findings in international counterpart studies. For men only, pornography consumption was found to significantly predict common sexual behaviours in non-marital relations. The study is the first to provide insights into prevalence rates and patterns of pornography consumption and its association with common non-marital sexual behaviours in a sexually conservative, Muslim-majority nation with strict anti-pornography laws.

    Assessment for Learning (AfL) is believed to create a rich learning environment in which students develop their cognitive and metacognitive strategies. Monitoring student growth and providing scaffolds that shed light on the next step in the learning process are hypothesized to be essential elements of AfL that enhance cognitive and metacognitive strategies. However, empirical evidence for the relation between AfL and students' strategy use is scarce. This study investigates the relation between AfL and elementary school students' use of cognitive and metacognitive strategies. The sample comprised 528 grade four to six students (9- to 12-year-olds) from seven Dutch elementary schools. Students' perceptions of AfL and their cognitive and metacognitive strategy use were measured by means of questionnaires. Structural equation modelling was used to investigate the relations among the variables. The results reveal that monitoring activities that provide students an understanding of where they are in their learning process predict Students' task orientation and planning. Scaffolding activities that support students in taking the next step in their learning are positively related to the use of both surface and deep-level learning strategies and the extent to which they evaluate their learning process after performing tasks. The results underline the importance of assessment practices in ceding responsibility to students in taking control of their own learning. © 2014 The British Psychological Society.

    2013-11-01

    Many studies have examined differences in sexual behavior based on sexual orientation with results often indicating that those with same-sex partners engage in higher risk sexual behavior than people with opposite sex partners. However, few of these studies were large, national sample studies that also include those identifying as unsure. To address that gap, this study examined the relationship of sexual orientation and sexual health outcomes in a national sample of U.S. college students. The Fall 2009 American College Health Association-National College Health Assessment was used to examine sexual health related responses from heterosexual, gay, lesbian, bisexual, and unsure students (N = 25,553). Responses related to sexual behavior, safer sex behaviors, prevention and screening behaviors, and diagnosis of sexual health related conditions were examined. The findings indicated that sexual orientation was significantly associated with engaging in sexual behavior in the last 30 days. Sexual orientation was also significantly associated with the number of sexual partners in the previous 12 months, with unsure men having significantly more partners than gay, bisexual and heterosexual men and heterosexual men having significantly less partners than gay, bisexual and unsure men. Bisexual women had significantly more partners than females reporting other sexual orientations. Results examining the associations between sexual orientation and safer sex, prevention behaviors, and screening behaviors were mixed. Implications for practice, including specific programmatic ideas, were discussed.

    What are the levels of awareness regarding female fertility and the intentions and attitudes towards parenthood among Chinese university students in Hong Kong compared with their counterparts in the West? Chinese university students in Hong Kong were similarly over-optimistic about the age-related fertility decline, although they were less inclined to have children and undergo fertility treatment compared with their Western counterparts. Past studies of highly educated young adults in Europe and the USA have found that they are not sufficiently aware of the age-related decline in female fertility, and falsely believe that advanced reproductive treatments such as IVF will overcome fertility problems associated with age. Little is known about the perceptions of Chinese students in Hong Kong, a modernized Chinese city where the fertility rate is among the lowest in the world. An online cross-sectional survey of Chinese university students in Hong Kong was conducted in 2013. Results were compared with two similar studies in Sweden and the USA. A total of 367 university students in Hong Kong (275 female, 92 male; mean age 23) responded to an e-mail invitation to participate in an online survey. Intentions and attitudes towards parenthood and awareness regarding female fertility were assessed using the Swedish Fertility Awareness Questionnaire. Like their Western counterparts, a large proportion of Chinese university students underestimated the age-related fertility decline (92%) and overestimated the fertility treatment success rate (66%). However, they were less inclined to have children, were more aware of and less concerned with infertility and were less motivated to seek solutions in the event of a fertility problem. These comparisons were significant at P International comparisons warrant caution because the Hong Kong sample was older than the US sample (mean age 20), but not older than the Sweden sample (mean age 24). While this study was consistent with past

    In March 2015, the Alcohol and Tobacco Tax and Trade Bureau approved the sale of Palcohol, the first powdered alcohol product to be marketed and sold in the U.S. Powdered alcohol is freeze-dried, and one individual-serving size packet added to 6 ounces of liquid is equivalent to a standard drink. This study assessed awareness of powered alcohol and likelihood to use and/or misuse powdered alcohol among college students. Surveys were administered to a convenience sample of 1,841 undergraduate students. Only 16.4% of respondents had heard of powdered alcohol. After being provided a brief description of powdered alcohol, 23% indicated that they would use the product if available, and of those, 62.1% also indicated likelihood of misusing the product (eg, snorting it, mixing it with alcohol). Caucasian students (OR = 1.5) and hazardous drinkers (based on AUDIT-C scores; OR = 4.7) were significantly more likely to indicate likelihood of use. Hazardous drinkers were also six times more likely to indicate likelihood to misuse the product. These findings can inform upstream prevention efforts in states debating bans on powdered alcohol. In states where powdered alcohol will soon be available, alcohol education initiatives should be updated to include information on the potential risks of use and be targeted to those populations most likely to misuse. This is the first peer-reviewed study to assess the awareness of and likelihood to use and/or misuse powdered alcohol, a potentially emerging form of alcohol. © American Academy of Addiction Psychiatry.

    Personal initiative characterizes people who are proactive, persistent and self-starting when facing the difficulties that arise in achieving goals. Despite its importance in the educational field there is a scarcity of measures to assess students' personal initiative. Thus, the aim of the present study was to develop a questionnaire to assess this variable in the academic environment and to validate it for adolescents and young adults. The sample comprised 244 vocational training students. The questionnaire showed a factor structure including three factors (Proactivity-Prosocial behavior, Persistence and Self-Starting) with acceptable indices of internal consistency (ranging between α = .57 and α =.73) and good convergent validity with respect to the Self-Reported Initiative scale. Evidence of external validity was also obtained based on the relationships between personal initiative and variables such as self-efficacy, enterprising attitude, responsibility and control aspirations, conscientiousness, and academic achievement. The results indicate that this new measure is very useful for assessing personal initiative among vocational training students.

    We analyse an asteroseismic binary system: KIC 7107778, a non-eclipsing, unresolved target, with solar-like oscillations in both components. We used Kepler short cadence time series spanning nearly 2 yr to obtain the power spectrum. Oscillation mode parameters were determined using Bayesian inference and a nested sampling Monte Carlo algorithm with the DIAMONDS package. The power profiles of the two components fully overlap, indicating their close similarity. We modelled the two stars with MESA and calculated oscillation frequencies with GYRE. Stellar fundamental parameters (mass, radius, and age) were estimated by grid modelling with atmospheric parameters and the oscillation frequencies of l = 0, 2 modes as constraints. Most l = 1 mixed modes were identified with models searched using a bisection method. Stellar parameters for the two sub-giant stars are MA = 1.42 ± 0.06 M⊙, MB = 1.39 ± 0.03 M⊙, RA = 2.93 ± 0.05 R⊙, RB = 2.76 ± 0.04 R⊙, tA = 3.32 ± 0.54 Gyr and tB = 3.51 ± 0.33 Gyr. The mass difference of the system is ˜1 per cent. The results confirm their simultaneous birth and evolution, as is expected from binary formation. KIC 7107778 comprises almost identical twins, and is the first asteroseismic sub-giant binary to be detected.

    2015-01-01

    This study examines how the changes in weight status across the spectrum of a senior high school study are associated with academic performance measured by the university entrance exam scores. A unique dataset which compiles a national health examination profile and the General Scholastic Ability Test data bank in Taiwan was constructed. The final sample comprised 149,240 senior high school students of which 70,662 were males and 78,578 were female students. The school-level fixed effect models were estimated. Students who were either (a) not overweight in the first year but overweight in the third year of senior high school, (b) overweight in both the first and third year, or (c) overweight in the first year but not overweight in the third year, were more likely to score lower on the university entrance exam, compared with their never-overweight counterparts. The findings differ by gender and test subjects. The change in weight status during senior high school period is associated with subsequent university entrance exam outcome. Students who start senior high school being overweight should be paid attention. School-based programs and practices need to be implemented to reduce the prevalence of overweight among students.

    Violence is a growing problem worldwide in the field of health care and within the nursing profession. A study comprising a survey and focus groups with nursing students, and interviews with nurse educators was conducted to examine nursing students' perceptions and experiences of violence at a nursing education institution in the Western Cape, South Africa. A self-administered questionnaire was distributed to all nursing students. Two hundred and twenty three (n = 223) respondents completed the questionnaire. Focus groups were conducted with purposively sampled student participants and semi-structured interviews with nurse educators. The findings indicated that the nature of the violent incidents experienced by students on campus, especially in the residences, ranged from verbal abuse to violation of students' property and personal space, and could be attributed primarily to substance abuse. Violence among student nurses could negatively affect learning. In a profession in which nurses are exposed to violence in the workplace, it is important that violence in the learning environment is actively prevented and respect of individual rights, tolerance and co-operation are promoted.

    1995-03-01

    Over the past 35 years, the study of die behavior and uses of free-jet expansions for laboratory experiments has greatly expanded and matured. Not the least of these uses of free-jet expansions, is that of extractive sampling from high temperature, reactive systems. The conversion of the free-jet expanded gases to molecular flow for direct introduction into the ion source of a mass spectrometer offers several advantages, to be illustrated in these pages. Two meetings on this subject were held in 1965 and 1972 in Missouri, sponsored by the Office of Naval Research and Midwest Research Institute. At these meetings rarefied gas dynamicists came together with scientists using free-jet sampling for analytical purposes. After much too long a time, this workshop was convened to bring together modem practitioners of FJMBS (Free-jet, Molecular-beam, mass spectrometry) and long time students of the free-jet process itself, to assess the current state of the art and to forge a community that can foster the development of this novel analytical approach. This proceedings is comprised of 38 individually submitted papers. Individual papers are indexed separately on the Energy Data Base.

    In recent times the basic understanding, perceptions and CAM use among undergraduate health sciences students have become a topic of interest. This study was aimed to investigate the understanding, perceptions and self-use of CAM among pharmacy students in Malaysia. This cross-sectional study was conducted on 500 systematically sampled pharmacy students from two private and one public university. A validated, self-administered questionnaire comprised of seven sections was used to gather the data. A systematic sampling was applied to recruit the students. Both descriptive and inferential statistics were applied using SPSS® version 18. Overall, the students tend to disagree that complementary therapies (CM) are a threat to public health (mean score = 3.6) and agreed that CMs include ideas and methods from which conventional medicine could benefit (mean score = 4.7). More than half (57.8%) of the participants were currently using CAM while 77.6% had used it previously. Among the current CAM modalities used by the students, CM (21.9%) was found to be the most frequently used CAM followed by Traditional Chinese Medicine (TCM) (21%). Most of the students (74.8%) believed that lack of scientific evidence is one of the most important barriers obstructing them to use CAM. More than half of the students perceived TCM (62.8%) and music therapy (53.8%) to be effective. Majority of them (69.3%) asserted that CAM knowledge is necessary to be a well-rounded professional. This study reveals a high-percentage of pharmacy students who were using or had previously used at least one type of CAM. Students of higher professional years tend to agree that CMs include ideas and methods from which conventional medicine could benefit.

    A questionnaire was developed and validated which assesses factors influencing career choices of medical students and their perception of possibilities in general practice. The first questionnaire version, which was developed based on a systematic literature review, was checked for comprehensibility and redundancy using concurrent think aloud. The revised version was filled out by a pilot sample of medical students and the factor structure was assessed using principal component analysis (PCA). The final version was filled out in an online survey by medical students of all 5 Medical Faculties in the federal state of Baden-Wuerttemberg. The factor structure was validated with a confirmatory factor analysis (CFA). Reliability was assessed as internal consistency using Cronbach's α. The questionnaire comprises 2 parts: ratings of (A) the individual importance and of (B) the possibilities in general practice on 5-point scales. The first version comprising 118 items was shortened to 63 items after conducting interviews using concurrent think aloud. A further 3 items giving no information were removed after piloting the questionnaire on 179 students. The 27 items of part A were structured in 7 factors (PCA): image, personal ambition, patient orientation, work-life balance, future perspectives, job-related ambition, and variety in job. This structure had a critical fit in the CFA applied to the final version filled out by 1 299 students. Internal consistency of the factors was satisfactory to very good (Cronbach's α=0.55-0.81). The questionnaire showed good psychometric properties. Further, not assessed factors influence career choice resulting in unexplained variance in our dataset and the critical fit of the model. © Georg Thieme Verlag KG Stuttgart · New York.

    Full Text Available Objective: Dental students are particularly affected by stress, which can lead to ‘burnout syndrome’ by association with other psychological factors. The aim of this study was to analyse the effect of perceived stress, coping strategies, and vocational satisfaction on the severity of burnout in Chilean dental students in the clinical years. Method: The study population was comprised of clinical dental students of five Chilean dental schools. The following variables were considered: age, gender, year of study, burnout, coping strategies, perceived stress, and vocational satisfaction. Statistical analysis included descriptive measures, correlation tests, and stepwise multiple regression analysis. Results: The final sample included 244 students. Three (1.23% students did not have burnout in any of its factors and 38 (15.57% had severe levels in all three factors. There was a statistically significant greater ‘emotional exhaustion’ in 4th year students. There was a statistically significant correlation of the three factors of burnout with ‘social withdrawal’ coping strategy, high levels of perceived stress, and low levels of present and future vocational satisfaction. Conclusion: Most students presented moderate and high levels of burnout. This situation is associated with dysfunctional coping strategies, high levels of perceived stress, and low levels of present and future vocational satisfaction.

    2015-09-01

    This study examined employment planning and career preferences of final year nursing students in Jordan. Focus group discussions (n = 4) were conducted by the first author with a convenience sample of 27 nursing students. N-Vivo 9 was used to analyze the qualitative data. The analysis revealed two themes. The first theme focused on "moving from study to work", and comprised two sub-themes: being uncertain and hesitant and being a real nurse. The second theme was "the place where I want to be", and referred to participants' preferences concerning their future career. Participants showed interest in critical care units but they were not optimistic about their future career prospects due to the possibility of being jobless and the perceived low public image of nurses. In addition to the nature of placement atmosphere, gender, family and cultural issues were found to shape participants' preferences. It is therefore important to periodically review the considerations of employment planning and career preferences of nursing students, otherwise devising interventions for sound recruitment of nurses in the future will be flawed.

    2017-12-01

    Role modelling by experienced nurses, including nurse academics, is a key factor in the process of preparing undergraduate nursing students for practice, and may contribute to longevity in the workforce. A grounded theory study was undertaken to investigate the phenomenon of nurse academics' role modelling for undergraduate students. The study sought to answer the research question: how do nurse academics role model positive professional behaviours for undergraduate students? The aims of this study were to: theorise a process of nurse academic role modelling for undergraduate students; describe the elements that support positive role modelling by nurse academics; and explain the factors that influence the implementation of academic role modelling. The study sample included five second year nursing students and sixteen nurse academics from Australia and the United Kingdom. Data was collected from observation, focus groups and individual interviews. This study found that in order for nurse academics to role model professional behaviours for nursing students, they must reconcile their own professional identity. This paper introduces the theory of reconciling professional identity and discusses the three categories that comprise the theory, creating a context for learning, creating a context for authentic rehearsal and mirroring identity.

    2017-04-01

    The aim of this study was to investigate the effect of writing a bachelor's thesis on nursing students' attitudes towards research and development in nursing. The study sample consisted of 91 nursing students who were required to complete a bachelor's thesis and 89 nursing students who were not required to complete a bachelor's thesis. Data were collected via self-report questionnaire that was distributed in May and June 2012. The questionnaire comprised 3 parts: (1) demographic items; (2) questions about "scientific activities," and (3) the nursing students' attitudes towards and awareness of research and development within nursing scale (version 2). The mean age of the students was 23 (1.3) years. The students who wrote a bachelor's thesis achieved a median score of 110.0, whereas the students in the other group had a median score of 105.0 on the scale. All the items were assigned a 3 or higher. A statistically significant difference was found between the 2 groups in their attitudes towards and awareness of research (U = 3265.5; P = .025). The results of this study suggest that writing a thesis in nursing education has a positive influence on nursing students' attitudes towards and awareness of research and development in nursing. © 2017 John Wiley & Sons Australia, Ltd.

    Tatem, E; Payne, J L

    2000-01-01

    This study was designed to measure the impact of a College of Nursing's (CON) Retention Program on students enrolled in a baccalaureate degree nursing program. Within the last ten years, undergraduate nurses increasingly have utilized the CON retention program. These students traditionally face a number of barriers to their academic endeavors. This study was designed to assess the effect of the CON program on the barriers to academic success of students who entered the CON in the Fall classes of 1991, 1992 and 1993. The sample size was 320 students. The control group consisted of 137 students who received no intervention and the experimental group was comprised of 183 students who attended intervention sessions with the Retention Coordinator in the CON. It was hypothesized that the most successful students during this period (1991-1993) were the most frequent attendees of the CON retention program intervention sessions. The alternative hypothesis was that those persons who did not attend the sessions, but were still highly persistent and successful, were enrollees who had entered with high entrance credentials as demonstrated by the transfer grade point averages (GPA). The results of this study indicated the need, use and value of this systematic approach to retention.

  13. Ability grouping of gifted students: effects on academic self-concept and boredom.

    Science.gov (United States)

    Preckel, Franzis; Götz, Thomas; Frenzel, Anne

    2010-09-01

    Securing appropriate challenge or preventing boredom is one of the reasons frequently used to justify ability grouping of gifted students, which has been shown to have beneficial effects for achievement. On the other hand, critics stress psychosocial costs, such as detrimental effects on academic self-concept (contrast or big-fish-little-pond effect). The effects of full-time ability grouping in special classrooms for the gifted on students' academic self-concept and their experience of boredom in mathematics classes were investigated. The sample comprised 186 ninth-grade students (106 male) from eight classes at one Austrian high school. Four of these classes were part of a gifted track beginning from school year 9 on (N=93). Students were assessed repeatedly within the first half of the school year, three times via self-report questionnaires and once by applying a standardized IQ-test. Students in gifted classes reported a decrease in maths academic self-concept which was most pronounced early in the academic year. Interventions to counterbalance the negative effect of exposure to a high-ability reference group should therefore be implemented when ability grouping begins. No evidence for the boredom hypothesis was found (higher levels of boredom among gifted students in regular classes). However, students clearly differed in the reasons they stated for experiencing boredom. Boredom attributions changed over time and supported the assumption that gifted classes provide more appropriate levels of challenge.

    2017-07-01

    Full Text Available The Multidimensional Students’ Life Satisfaction Scale is an instrument to assess life satisfaction in children and adolescents in five life domains. However, research on multidimensional life satisfaction in older students, such as those attending university, is still scarce. This paper undertook to evaluate the psychometric properties of the Multidimensional Students’ Life Satisfaction Scale in a sample of university students from five state universities in Chile. The Multidimensional Students’ Life Satisfaction Scale and Satisfaction with Life Scale were applied to 369 participants. Confirmatory factor analysis was used to evaluate the expected correlated five-factor model of the long version (40 items and the abbreviated version (30 items of the Multidimensional Students’ Life Satisfaction Scale. The goodness-of-fit values obtained from confirmatory factor analysis revealed that the data fit better to the 30-items and five-factor structure than to the 40-item structure. The convergent, concurrent and discriminant validity of the 30-item version was demonstrated. The 30-item version of the Multidimensional Students’ Life Satisfaction Scale may be a promising alternative to measure satisfaction in different life domains in university students, and a valuable tool for differential assessments that guide research and intervention on this population.

    Harvey, Robert Christopher

    The purpose of this study was to determine the effects of two conceptually based instructional strategies on science achievement and attitudes of community college biological science students. The sample consisted of 277 students enrolled in General Biology 1, Microbiology, and Human Anatomy and Physiology 1. Control students were comprised of intact classes from the 2005 Spring semester; treatment students from the 2005 Fall semester were randomly assigned to one of two groups within each course: written narrative (WN) and illustration (IL). WN students prepared in-class written narratives related to cell theory and metabolism, which were taught in all three courses. IL students prepared in-class illustrations of the same concepts. Control students received traditional lecture/lab during the entire class period and neither wrote in-class descriptions nor prepared in-class illustrations of the targeted concepts. All groups were equivalent on age, gender, ethnicity, GPA, and number of college credits earned and were blinded to the study. All interventions occurred in class and no group received more attention or time to complete assignments. A multivariate analysis of covariance (MANCOVA) via multiple regression was the primary statistical strategy used to test the study's hypotheses. The model was valid and statistically significant. Independent follow-up univariate analyses relative to each dependent measure found that no research factor had a significant effect on attitude, but that course-teacher, group membership, and student academic characteristics had a significant effect (p < .05) on achievement: (1) Biology students scored significantly lower in achievement than A&P students; (2) Microbiology students scored significantly higher in achievement than Biology students; (3) Written Narrative students scored significantly higher in achievement than Control students; and (4) GPA had a significant effect on achievement. In addition, given p < .08: (1

    2011-01-01

    The aim of the present study was to investigate the relationship between compulsive buying (CB), eating disorder symptoms, and temperament (controlling for depression) in a sample of female students. We assessed 211 female undergraduate students using the Compulsive Buying Scale, the Eating Disorder Inventory, the Behavioral Inhibition System and Behavioral Activation System scales, the Adult Temperament Questionnaire, and the Physical Health Questionnaire-Depression. The results show a positive association between CB and the Eating Disorder Inventory-II drive for thinness and bulimia subscales. Both CB and eating disorder symptoms were related to low levels of effortful control. Finally, CB was also related to high levels of Behavioral Activation Scale reactivity (impulsivity), whereas eating disorder symptoms (especially drive for thinness) were more strongly related to high levels of Behavioral Inhibition Scale reactivity (anxiety). The implications of these findings for the treatment of CB and eating disorder symptoms will be discussed. © 2011 Elsevier Inc. All rights reserved.

  2. Predictors of student success in entry-level science courses

    Science.gov (United States)

    Singh, Mamta K.

    Although the educational evaluation process is useful and valuable and is supported by the Higher Education Act, a strong research base for program evaluation of college entry-level science courses is still lacking. Studies in science disciplines such as, biology, chemistry, and physics have addressed various affective and demographic factors and their relationships to student achievement. However, the literature contains little information that specifically addresses student biology content knowledge skills (basics and higher order thinking skills) and identifies factors that affect students' success in entry-level college science courses. These gate-keeping courses require detailed evaluation if the goal of an institution is to increase students' performance and success in these courses. These factors are, in fact, a stepping stone for increasing the number of graduates in Science, Technology, Engineering, and Mathematics (STEM) majors. The present study measured students' biology content knowledge and investigated students' performance and success in college biology, chemistry, and physics entry-level courses. Seven variables---gender, ethnicity, high school Grade Point Average (GPA), high school science, college major, school financial aid support, and work hours were used as independent variables and course final performance as a dichotomous dependent variable. The sample comprised voluntary student participants in entry-level science courses. The study attempted to explore eight research questions. Content knowledge assessments, demographic information analysis, multiple regression analysis, and binary logistic regression analysis were used to address research questions. The results suggested that high school GPA was a consistently good predictor of students' performance and success in entry-level science courses. Additionally, high school chemistry was a significant predictor variable for student success in entry-level biology and chemistry courses

    Full Text Available Bacterial artificial chromosome (BAC clones have proven invaluable for genetic manipulation of herpesvirus genomes. BAC cloning can also be useful for capturing representative genomes that comprise a viral stock or mixture. The Towne live attenuated cytomegalovirus vaccine was developed in the 1970s by serial passage in cultured fibroblasts. Although its safety, immunogenicity, and efficacy have been evaluated in nearly a thousand human subjects, the vaccine itself has been little studied. Instead, genetic composition and in vitro growth properties have been inferred from studies of laboratory stocks that may not always accurately represent the viruses that comprise the vaccine. Here we describe the use of BAC cloning to define the genotypic and phenotypic properties of viruses from the Towne vaccine. Given the extensive safety history of the Towne vaccine, these BACs provide a logical starting point for the development of next-generation rationally engineered cytomegalovirus vaccines.

    Full Text Available Introduction: Professional education program is a program in which nursing students are transformed to become professional nurses. At this level, nursing students will encounter various stressors. The purpose of this study was to analyze the relationship between stressors, relational meaning and coping strategy on burnout syndrome in nursing students who are undergoing professional education. Method: This was a correlational study using cross-sectional approach. Population comprised regular student of nursing profession program at the Faculty of Nursing, Airlangga University. Sample size was determined by simple random sampling and 61 persons were included in the inclusion criteria. Data then analyzed using multiple linear regression test with signi fi cance level ofα < 0.05. Results: This study found that total burnout syndrome was signi fi cantly related to relational meaning (p = 0.005, β = 0.460. Emotional exhaustion was signi fi cantly related to relational meaning (p= 0.001, β = 0.532 and emotion focused coping (p = 0.035, β =0.298. Relational meaning was also signifi cantly related to depersonalization (p = 0.002, β = 0.050. Subsequently, the decline in self-achievement was signi fi cantly related to personal stressors, i.e the number of room mates (p = 0.016, β = 0.344, total learning time/day (p = 0.036, β=0.366 and environmental stressors (workload (p = 0.039, β = -0.349.

    Psychological distress and suicidal behavior are important mental health problems among university students and warrant research to inform strategies for effective prevention in this young population. The present study aimed to assess psychological distress and suicidal behavior and to unravel their associations among university students. A total of 5972 undergraduate students, randomly selected from six universities in central China, comprised the sample. The Chinese version of the Symptom Checklist-90-revised (SCL-90-R) was used to assess various psychological symptoms. Logistic regression analysis was used to examine the relationship between psychological distress and risk for suicidal behavior. 40.7% of the university students reported positive in a least one of the 9 psychological symptom dimensions assessed by the SCL-90-R. 7.6% of the students reported suicidal behavior in the previous twelve months. The risk of suicidal behavior was significantly associated with psychological symptoms of all types, but there were notable differences by sex. For male students, depression and phobic anxiety increased the risk of suicidal behavior. Meanwhile, depression and obsessive-compulsiveness were positively associated with suicidal behavior in female students. Furthermore, increasing risk of suicidal behavior was associated with increasing positive symptom total (PST) score and a statistically significant trend was observed. Data collected from a cross-sectional survey does not allow any examination of causal inference. Psychological distress and suicidal behavior were both common among university students; and psychological distress was highly associated with suicidal behavior. The findings underscore the importance of mental health care for university students. Copyright © 2017 Elsevier B.V. All rights reserved.

    Although there is considerable evidence to support the direct effects of self-efficacy beliefs on academic achievement, very few studies have explored the motivational mechanism that mediates the self-efficacy-achievement relationship, and they are necessary to understand how and why self-efficacy affects students' academic achievement. Based on a socio-cognitive perspective of motivation, this study examines the relationships among academic self-efficacy, students' expectancy-value beliefs, teaching process satisfaction, and academic achievement. Its main aim is to identify some motivational-underlying processes through which students' academic self-efficacy affects student achievement and satisfaction. Student achievement and satisfaction are two of the most important learning outcomes, and are considered key indicators of education quality. The sample comprises 797 Spanish secondary education students from 36 educational settings and three schools. The scales that referred to self-efficacy and expectancy-value beliefs were administered at the beginning of the course, while student satisfaction and achievement were measured at the end of the course. The data analysis was conducted by structural equation modeling (SEM). The results revealed that students' expectancy-value beliefs (Subject value, Process expectancy, Achievement expectancy, Cost expectancy) played a mediator role between academic self-efficacy and the achievement/satisfaction relationship. These results provided empirical evidence to better understand the mechanism that mediates self-efficacy-achievement and efficacy-course satisfaction relationships. The implications of these findings for teaching and learning in secondary education are discussed.

    Full Text Available The objective of this research has been to compare the levels of and to establish the connection between results of psychology students and their parents in relation to nationalism and cosmopolitanism and collectivism, and to horizontal and vertical individualism. In addition, an attempt has been made to define the contribution of socio-demographic variables, the importance of religion and the ideological orientation of the respondents along with collectivism/individualism in explaining the pronounced nature of nationalism and/or cosmopolitanism among the students and their parents. The research was carried out on a group of 200 students (26 male and 174 female and 296 parents (143 male and 153 female, all of Croatian nationality. Three questionnaires were applied: the Nationalism and Cosmopolitanism Scale (Čorkalo and Kamenov, 1999, the HVIC questionnaire on horizontal and vertical individualism and collectivism (Singelis et al., 1995 and a socio-demographic questionnaire. The results showed that parents of students express more marked nationalism and collectivism than their (adult children, while students express more marked cosmopolitanism and horizontal individualism than their parents. However, as far as vertical individualism is concerned, there is no difference between the average results of students and parents. The correlation between the collectivism and individualism of students and their mothers and fathers is lower than that between nationalism and cosmopolitanism. The set of socio-demographic predictors, the importance of religion, ideological orientations and collectivism/individualism more reliably foresee nationalism rather than cosmopolitanism, both in the parental and student sample. The type and contribution of the individual predictors are similar in both samples, with the exception of certain socio-demographic predictors that were shown to be significant in the parental, but not in the student sample.

    Small changes in the synthesis of MnAs nanoparticles lead to materials with distinct behavior. Samples prepared by slow heating to 523 K (type-A) exhibit the characteristic magnetostructural transition from the ferromagnetic hexagonal (α) to the paramagnetic orthorhombic (β) phase of bulk MnAs at Tp = 312 K, whereas those prepared by rapid nucleation at 603 K (type-B) adopt the β structure at room temperature and exhibit anomalous magnetic properties. The behavior of type-B nanoparticles is due to P-incorporation (up to 3%), attributed to reaction of the solvent (trioctylphosphine oxide). P-incorporation results in a decrease in the unit cell volume (∼1%) and shifts Tp below room temperature. Temperature-dependent X-ray diffraction reveals a large region of phase-coexistence, up to 90 K, which may reflect small differences in Tp from particle-to-particle within the nearly monodisperse sample. The large coexistence range coupled to the thermal hysteresis results in process-dependent phase mixtures. As-prepared type-B samples exhibiting the β structure at room temperature convert to a mixture of α and β after the sample has been cooled to 77 K and rewarmed to room temperature. This change is reflected in the magnetic response, which shows an increased moment and a shift in the temperature hysteresis loop after cooling. The proportion of α present at room temperature can also be augmented by application of an external magnetic field. Both doped (type-B) and undoped (type-A) MnAs nanoparticles show significant thermal hysteresis narrowing relative to their bulk phases, suggesting that formation of nanoparticles may be an effective method to reduce thermal losses in magnetic refrigeration applications.

  1. The effect of instructional methodology on high school students natural sciences standardized tests scores

    Powell, P. E.

    Educators have recently come to consider inquiry based instruction as a more effective method of instruction than didactic instruction. Experience based learning theory suggests that student performance is linked to teaching method. However, research is limited on inquiry teaching and its effectiveness on preparing students to perform well on standardized tests. The purpose of the study to investigate whether one of these two teaching methodologies was more effective in increasing student performance on standardized science tests. The quasi experimental quantitative study was comprised of two stages. Stage 1 used a survey to identify teaching methods of a convenience sample of 57 teacher participants and determined level of inquiry used in instruction to place participants into instructional groups (the independent variable). Stage 2 used analysis of covariance (ANCOVA) to compare posttest scores on a standardized exam by teaching method. Additional analyses were conducted to examine the differences in science achievement by ethnicity, gender, and socioeconomic status by teaching methodology. Results demonstrated a statistically significant gain in test scores when taught using inquiry based instruction. Subpopulation analyses indicated all groups showed improved mean standardized test scores except African American students. The findings benefit teachers and students by presenting data supporting a method of content delivery that increases teacher efficacy and produces students with a greater cognition of science content that meets the school's mission and goals.

    To assess the effects of attention-deficit/hyperactivity disorder (ADHD) symptom dimensions on Internet addiction (IA) after controlling for Internet usage features among high school students. This study consisted of 640 students (331 females and 309 males) ranging from 14 to 19 years of age. The Internet Addiction Scale, the Conners-Wells' Adolescent Self-Report Scale-Short Form, and a personal information form were completed by the participants. Statistical analyses were conducted for both sexes and the total sample. According to the logistic regression analysis, attention deficit and playing online games were significant predictors of IA in both sexes. Other predictors of IA included behavioral problems for females, total weekly Internet usage time, and lifelong total Internet use for males. Hyperactivity and other Internet usage features did not predict IA. These results suggest that attention deficit and playing online games are important determinants of IA in this age group.

  6. Sample vial inserts: A better approach for sampling heterogeneous slurry samples in the SRS Defense Waste Processing Facility

    International Nuclear Information System (INIS)

    Coleman, C.J.; Goode, S.R.

    1996-01-01

    A convenient and effective new approach for analyzing DWPF samples involves the use of inserts with volumes of 1.5--3 ml placed in the neck of 14 ml sample vials. The inserts have rims that conform to the rim of the vials so that they sit straight and stable in the vial. The DWPF tank sampling system fills the pre-weighed insert rather than the entire vial, so the vial functions only as the insert holder. The shielded cell operator then removes the vial cap and decants the insert containing the sample into a plastic bottle, crucible, etc., for analysis. Inert materials such as Teflon, plastic, and zirconium are used for the insert so it is unnecessary to separate the insert from the sample for most analyses. The key technique advantage of using inserts to take DWPF samples versus filling sample vials is that it provides a convenient and almost foolproof way of obtaining and handling small volumes of slurry samples in a shielded cell without corrupting the sample. Since the insert allows the entire sample to be analyzed, this approach eliminates the errors inherent with subsampling heterogeneous slurries that comprise DWPF samples. Slurry samples can then be analyzed with confidence. Analysis times are dramatically reduced by eliminating the drying and vitrification steps normally used to produce a homogeneous solid sample. Direct dissolution and elemental analysis of slurry samples are achieved in 8 hours or less compared with 40 hours for analysis of vitrified slurry samples. Comparison of samples taken in inserts versus full vials indicate that the insert does not significantly affect sample composition

    This paper aimed to determine the relationship between cancer information scanning and seeking experience of adolescents and cancer preventive behavior, perceived cancer risk, and levels of cancer- related knowledge. The study sample comprised 1,000 second-year students from 6 high schools: the general and vocational school systems were each represented by 1 boys', 1 girls', and 1 coeducational high school. In July 2011, trained researchers visited each classroom, explained the purpose of the study, distributed questionnaires to the students who agreed to participate, instructed them to complete the survey by self-reporting, and collected the completed questionnaires. The students who attended general high schools (as compared with vocational high schools), earned higher grades, consumed more vegetables, had a higher perceived cancer risk, and answered the cancer-related questions more correctly and had more cancer information scanning and seeking experience. These results reinforce the importance of cancer prevention health education. Furthermore, the results may help in preparing a strategy that enables people to acquire accurate cancer-related information easily and quickly.

The nursing profession, in particular nurse educators, has an ethical and professional responsibility to find innovative strategies to promote the positive image of nursing amongst student nurses. Purpose: The purpose of the study was to explore the potential of appreciative inquiry (AI as an intervention teaching strategy to transform student nurses’ image of nursing. Design: A quantitative, quasi-experimental, explorative-descriptive design comprising the pretest, appreciative inquiry as intervention, and the post-test was used. Methods: Convenience sampling was used to select third and fourthyear college and university student nurses in the Gauteng province of South Africa for the pre- and the post-test respectively. Data were collected by means of a questionnaire and analysed by SPSS version 20.0. Findings: The pretest results revealed a mix of positive and negative perceptions of the image of nursing amongst student nurses. The negative perceptions of the image of nursing that needed intervention included the working conditions of nurses, and the perception of nursing as a profession that was not respected and appreciated. The post-test results showed a significant and positive change in the student nurses’ perception of the image of nursing as a respected and appreciated profession. Although AI resulted in a negative to positive change in some aspects of student nurses’ image of nursing, the negative perceptions of the working conditions of nurses remained and became more negative. The positive image of gender in nursing was enhanced following the implementation of AI.

    As a developing country, Malaysia faces challenging tasks to develop her economy just like many other countries. Nowadays, change involves many aspects like the economy from agriculture to manufacturing, technology from modern to more advanced ones; mindset from traditional to advanced and so on. Previous studies show that one of the major issues facing local graduates is the lack of employability skills. This problem concerns not only the government but undergraduates and institutions alike. From the pedagogical aspect, one of the more effective ways to improve this is through instructional delivery and in this case the use of Problem-based Learning (PBL). The need to adopt PBL should involved applied subjects undertaken by engineering students. Studies have shown that the use of PBL has been proven to make learning more attractive and effective. In this research, we studied the effectiveness of PBL towards enhancing employability skills among engineering undergraduates. This study adopted a combination of qualitative and quantitative approaches. Data was collected using documents analysis. Student samples comprised manufacturing engineering undergraduates from public institutions of higher learning in Malaysia. The results show that student’s employability skills can be enhanced using PBL. In addition, students become more competitive towards making them more relevance with the needs of the industry with regard to employability skills. In conclusion, PBL is a very effective catalyst towards raising the employability skills among engineering undergraduates and should be adopted in all engineering education.

    Submicrorepresentations (SMRs) are a powerful tool for identifying misconceptions of chemical concepts and for generating proper mental models of chemical phenomena in students' long-term memory during chemical education. The main purpose of the study was to determine which independent variables (gender, formal reasoning abilities, visualization abilities, and intrinsic motivation for learning chemistry) have the maximum influence on students' reading and drawing SMRs. A total of 386 secondary school students (aged 16.3 years) participated in the study. The instruments used in the study were: test of Chemical Knowledge, Test of Logical Thinking, two tests of visualization abilities Patterns and Rotations, and questionnaire on Intrinsic Motivation for Learning Science. The results show moderate, but statistically significant correlations between students' intrinsic motivation, formal reasoning abilities and chemical knowledge at submicroscopic level based on reading and drawing SMRs. Visualization abilities are not statistically significantly correlated with students' success on items that comprise reading or drawing SMRs. It can be also concluded that there is a statistically significant difference between male and female students in solving problems that include reading or drawing SMRs. Based on these statistical results and content analysis of the sample problems, several educational strategies can be implemented for students to develop adequate mental models of chemical concepts on all three levels of representations.

    Full Text Available This study sought to shed light on the relationship between communicative activities and their impact on students’ motivation to learn English as a Foreign Language (EFL. A total of 180 senior high school learners (86 male and 94 female and 8 EFL teachers in a town of the Amazon region of Ecuador completed a questionnaire. A sample of these students and all of the teachers participated in a face-to-face interview. Both instruments were applied to obtain data concerned with use of communicative activities in the classroom and their relation with motivation. The data gathered was analyzed using a mixed-method approach, which comprised quantitative and qualitative methods. The results showed that students and teachers believe that communicative activities are motivating. Furthermore, students feel highly motivated when participating in interactive activities because these enhance their fluency, pronunciation and performance in the use of English in a realistic and enjoyable way.

    During my summer student programme I was working on sample optimization for a new β-NMR project at the ISOLDE facility. The β-NMR technique is well-established in solid-state physics and just recently it is being introduced for applications in biochemistry and life sciences. The β-NMR collaboration will be applying for beam time to the INTC committee in September for three nuclei: Cu, Zn and Mg. Sample optimization for Mg was already performed last year during the summer student programme. Therefore sample optimization for Cu and Zn had to be completed as well for the project proposal. My part in the project was to perform thorough literature research on techniques studying Cu and Zn complexes in native conditions, search for relevant binding candidates for Cu and Zn applicable for ß-NMR and eventually evaluate selected binding candidates using UV-VIS spectrometry.

    This study was designed to assess undergraduates' (N = 424) definitions of binge drinking and to evaluate whether the number of drinks they said comprise a binge varied as a function of beverage type, respondent gender, and respondent binge drinking status. When asked to designate the specific number of drinks that comprise a binge for each of four beverage types, students reported that the number of beers constituting a binge was significantly larger than the number of glasses of wine, shots of hard liquor, and servings of any combination of alcoholic beverage types; men reported that a larger number of drinks constitute a binge than did women; and those who had engaged in 3 or more binges in the past 2 weeks reported that more drinks comprise a binge than those who had binged less often. Responses to an open-ended question asking their definition of a binge revealed that students sometimes characterize a binge in terms of motivations for and unhealthy consequences of drinking, in addition to defining a binge as comprising consumption of a large amount of alcohol in a limited (though often unspecified) time period. Furthermore, students attributed their open-ended definitions of binge drinking to informal sources of information and observation of others' drinking almost as often as they did to school-based or media-based sources. This suggests that educators might look for innovative ways to use both formal and informal social networking, and video illustrations of restrained drinking, as ways to influence young people's views of binge drinking.

    Obesity and the lifestyle characteristic of Indian society lead young people to conditions of potential cardiovascular risk. The purpose of this study was to assess the prevalence of overweight/obesity and central obesity and its associated factors in a sample of Indian university students. In a cross-sectional survey assessed anthropometric measurements and a self-administered questionnaire among a sample of randomly selected university students. The sample included 800 university students from non health (mainly sciences) courses Gitam University in India. The students were 541 (67.6%) males and 259 (32.4%) females in the age range of 17-20 years (M age 18.2 years, SD=1.0). 37.5% were overweight or obese, 26.8% overweight (≥23-27.4 BMI) and 10.7% obese (≥27.5 kg/m(2)), 11.7% underweight (obesity (WC ≥90 cm for men and ≥80 cm for women). In multivariate analysis among men lack of non-organised religious activity (odds ratio=OR 0.85, confidence interval=CI 0.77-0.95), lower dietary risk knowledge (OR=0.64, CI=0.41-0.99), tobacco use (OR=2.23, CI=1.14-4.38), and suffering from depression (OR=1.59, CI=1.00-2.47) were associated with overweight/obesity, and younger age (OR=0.32, CI=0.12-0.90), lives away from parents or guardians (OR=1.79, CI=1.04-3.07), healthy dietary practices (OR=1.95, CI=1.02-3.72) and 9 or more hours sleep duration (OR=0.28, CI=0.09-0.96) were associated with central obesity. In bivariate analysis among women, lack of social support, lower dietary risk knowledge, tobacco use, and 9 or more hours sleep duration were associated with overweight/obesity and lives away from parents or guardians and abstinence from alcohol associated with central obesity. The study found a high prevalence of overweight/obesity and central obesity. Several gender specific health risk practices were identified including lack of dietary risk knowledge, shorter sleep duration, living away from parents or guardians, tobacco use and lack of social support and

    Objectives To estimate the prevalence of prescription medication diversion among college students; to compare classes of medications with respect to the likelihood of diversion; to document the most common methods of diversion; and to examine the characteristics of students who diverted medications. Method A cross-sectional analysis of personal interview data collected between August 2006 and August 2007 as part of an ongoing longitudinal study. The cohort of students, who were between the ages 17 and 19 at study onset, attended a large public university in the mid-Atlantic region. Information was gathered regarding a wide variety of variables, including demographics, diversion of medically prescribed drugs, illicit drug use, and childhood conduct problems. Results Among 483 students prescribed a medication, 35.8% diverted a medication at least once in their lifetime. The most commonly diverted medication classes were prescription ADHD medication, with a 61.7% diversion rate, and prescription analgesics (35.1% diversion rate). Sharing was the most common method of diversion, with 33.6% of students sharing their medication(s) and 9.3% selling in their lifetime. Comparative analyses revealed that prescription medication diverters had used more illicit drugs in the past year and had more childhood conduct problems than non-diverters. Conclusions If confirmed, these findings have important clinical implications for improved physician-patient communication and vigilance regarding prescribing analgesic and stimulant medications for young adults.

    Full Text Available The cell phone is ever-present on college campuses and is frequently used in settings where learning occurs. This study assessed the relationship between cell phone use and actual college grade point average (GPA after controlling for known predictors. As such, 536 undergraduate students from 82 self-reported majors at a large, public university were sampled. A hierarchical regression (R2 = .449 demonstrated that cell phone use was significantly (p < .001 and negatively (β = −.164 related to actual college GPA after controlling for demographic variables, self-efficacy for self-regulated learning, self-efficacy for academic achievement, and actual high school GPA, which were all significant predictors (p < .05. Thus, after controlling for other established predictors, increased cell phone use was associated with decreased academic performance. Although more research is needed to identify the underlying mechanisms, findings suggest a need to sensitize students and educators about the potential academic risks associated with high-frequency cell phone use.

    To examine the global prevalence of depression among nursing students and the variation in depression rates influenced by demographic and educational factors. Depression affects approximately 350 million people worldwide and is the world's leading cause of disability. Nursing students struggle to cope with not only stressors common in higher education institutions but also anxiety towards clinical placements. Evidence has suggested high prevalence of depression among them, but no reviews have been conducted to report a consolidated prevalence. Systematic review and meta-analysis. A search was conducted from November 2015 to January 2016 on CINAHL, EMBASE, Medline OVID, Medline ProQuest, PsycINFO, PubMed, ScienceDirect, and SCOPUS, using a combination of keywords "depression", "nursing students", "mood disorder", "affective disorder", 'undergraduate nursing', "nursing education", "nursing undergraduate", and "nursing diploma". A total of 27 cross-sectional studies were included. The sample comprised 8918 nursing students and the mean age ranged from 17.4 to 28.4 years. Among these studies, the proportion of female students ranged from 79.0% to 100.0%. A high pooled prevalence of depression of 34.0% was reported among nursing students. Significant differences in depression prevalence were noted for different subgroups of age, with a higher prevalence noted in younger students (41.0%), and for different geographical regions, with Asian nursing students experiencing a higher prevalence of depression (43.0%). No significant difference was noted between nursing and non-nursing students. The findings suggest a high prevalence of depression among nursing students. This serves as an impetus for educational reforms in nursing schools and proposes for further research to aid prospective nurses in safeguarding their psychological wellbeing. In the long run, it is imperative that competent nurses be nurtured to improve the standards of healthcare and patients' quality of life

    A method of fabricating a nuclear fuel comprising a fissile material, one or more hollow microballoons, a phenolic resin, and metal matrix. The fissile material, phenolic resin and the one or more hollow microballoons are combined. The combined fissile material, phenolic resin and the hollow microballoons are heated sufficiently to form at least some fissile material carbides creating a nuclear fuel particle. The resulting nuclear fuel particle comprises one or more fission product collection spaces. In a preferred embodiment, the fissile material, phenolic resin and the one or more hollow microballoons are combined by forming the fissile material into microspheres. The fissile material microspheres are then overcoated with the phenolic resin and microballoon. In another preferred embodiment, the fissile material, phenolic resin and the one or more hollow microballoons are combined by overcoating the microballoon with the fissile material, and phenolic resin.

    Binge drinking (BD) is prevalent among college students. Studies on alcoholism have shown that the prefrontal cortex is vulnerable to the neurotoxic effects of alcohol. The prefrontal cortex undergoes both structural and functional changes during adolescence and young adulthood. Sex differences have been observed in brain maturation and in alcohol-induced damage. The objective of the present study was to analyze the relationship between BD and cognitive functions subserved by the prefrontal cortex in male and female university students. The sample comprised 122 undergraduates (aged 18 to 20 years): 62 BD (30 females) and 60 non-BD (29 females). Executive functions were assessed by WMS-III (Backward Digit Span and Backward Spatial Span), SOPT (abstract designs), Letter Fluency (PMR), BADS (Zoo Map and Key Search) and WCST-3. BD students scored lower in the Backward Digit Span Subtest and generated more perseverative responses in the SOPT In relation to interaction BD by sex, BD males scored lower in the Backward Digit Span test than BD females and non-BD males. BD is associated with poorer performance of executive functions subserved by the dorsolateral prefrontal cortex. The results do not support enhanced vulnerability of women to alcohol neurotoxic effects. These difficulties may reflect developmental delay or frontal lobe dysfunction.

    A microfluidic platform was developed to perform online electrokinetic sample preconcentration and rapid hydrodynamic sample injection for zone electrophoresis using a single microvalve. The polydimethylsiloxane microchip comprises a separation channel, a side channel for sample introduction, and a control channel which is used as a pneumatic microvalve aligned at the intersection of the two flow channels. The closed microvalve, created by multilayer soft lithography, serves as a nanochannel preconcentrator under an applied electric potential, enabling current to pass through while preventing bulk flow. Once analytes are concentrated, the valve is briefly opened and the stacked sample is pressure injected into the separation channel for electrophoretic separation. Fluorescently labeled peptides were enriched by a factor of ∼450 in 230 s. This method enables both rapid analyte concentration and controlled injection volume for high sensitivity, high-resolution CE. © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    Validating a questionnaire/instrument before proceeding to the field for data collection is important. An 18-item breastfeeding intention, 39-item attitude and 44-item knowledge questionnaire was validated in a Croatian sample of secondary-school students ( N = 277). For the intentions, principal component analysis (PCA) yielded a four-factor solution with 8 items explaining 68.3% of the total variance. Cronbach’s alpha (0.71) indicated satisfactory internal consistency. For the attitudes, PCA showed a seven-factor structure with 33 items explaining 58.41% of total variance. Cronbach’s alpha (0.87) indicated good internal consistency. There were 13 knowledge questions that were retained after item analysis, showing good internal consistency (KR20 = 0.83). In terms of criterion validity, the questionnaire differentiated between students who received breastfeeding education compared to students who were not educated in breastfeeding. Correlations between intentions and attitudes (r = 0.49), intentions and knowledge (r = 0.29), and attitudes and knowledge (r = 0.38) confirmed concurrent validity. The final instrument is reliable and valid for data collection on breastfeeding. Therefore, the instrument is recommended for evaluation of breastfeeding education programs aimed at upper-grade elementary and secondary school students.

    The aim was to examine main reasons for students' medical school choice and their relationship with students' characteristics and motivation during the students' medical study. In this multisite cross-sectional study, all Year-1 and Year-4 students who had participated in a selection procedure in one of the three Dutch medical schools included in the study were invited to complete an online survey comprising personal data, their main reason for medical school choice and standard, validated questionnaires to measure their strength of motivation (Strength of Motivation for Medical School-Revised) and autonomous and controlled type of motivation (Academic Self-regulation Questionnaire). Four hundred seventy-eight students participated. We performed frequency analyses on the reasons for medical school choice and regression analyses and ANCOVAs to study their associations with students' characteristics and motivation during their medical study. Students indicated 'city' (Year-1: 24.7%, n=75 and Year-4: 36.0%, n=52) and 'selection procedure' (Year-1: 56.9%, n=173 and Year-4: 46.9%, n=68) as the main reasons for their medical school choice. The main reasons were associated with gender, age, being a first-generation university student, ethnic background and medical school, and no significant associations were found between the main reasons and the strength and type of motivation during the students' medical study. Most students had based their medical school choice on the selection procedure. If medical schools desire to achieve a good student-curriculum fit and attract a diverse student population aligning the selection procedure with the curriculum and taking into account various students' different approaches is important.

    Depression is one of the most common psychological disorders in individuals seeking psychiatric treatment, and a frequent psychological disorder among patients who seek primary healthcare. Therefore, it is vitally important to employ reliable and valid diagnostic instruments and norms, both in clinical and research work to investigate this problem. This article is part of a larger study which has been conducted for ten years now with the aim to create a clearer picture about the level of depression which may be expected in the nonclinical population in Serbia, and in that way provide a basis for comparisons when diagnosing the clinical population. The subsidiary aims were to monitor potential changes in level of depressive reactions within the set time and to examine the psychometric properties and factor structure of the Beck Depression Inventory (BDI) scale. The sample consisted of 782 students (40% male, 60% female), mean age = 23.10 years, SD = 1.782. Mean score on the BDI-IA scale was 6.69; SD = 6.412. The study showed no significant relationships between the BDI scores and sociodemographic variables such as age, economic status, and educational profile, but showed significant differences within gender (t (780) = 3.222, p = 0.001). There was also a relatively stable level of depressive reactions in this population over the previous ten years. The Cronbach's coefficient of the BDI scale was alpha = 0.860, with the majority of item-total correlations above 0.37. The three-factor structure represents cognitive aspect, affective component of depression, and somatic problems attached to depression. The cognitive factor prevails in the entire sample, which is in accordance with the Beck theory about dysfunctional attitudes, ie cognitive vulnerability is a psychological predisposition to depression.

    Full Text Available The objective of the present study was to investigate the relationship between time management, perceived stress, gender and academic achievement among United Arab Emirates college students. The respondents were 352 college students from Al Ain University of Science and Technology. The sample was stratified by sex. Among the respondents, 52.5% were female students and 47.5% were male students. The mean age of the sample was 23.4 years ranging from 18 to 39. Time management was measured by Time Management Questionnaire” developed by Britton and Tesser (1991, while perceived stress was measured by The Perceived Stress Scale developed by Cohen (1985. The findings of the study showed that there was statistically significant negative relationship between time management and perceived stress. Females reported higher time management compared to their males counter mates. Higher time management and lower perceived stress were associated with high levels of academic achievement. However, time management was the most significant predictor of academic achievement accounting for 26 % of the variance while perceived stress accounted for an additional 11.2% of the variance in academic achievement. All three predictors explained 29.4% (R = .543 of total variance. The implications and limitations are reviewed as are the suggestions for future research.   Keywords: Time management, perceived stress, academic achievement, college students.

    To create a self-sufficient, innovative method for providing cardiopulmonary resuscitation (CPR) education within a college of pharmacy using a student-driven committee, and disseminating CPR education into the community through a service learning experience. A CPR committee comprised of doctor of pharmacy (PharmD) students at the University of Tennessee College of Pharmacy provided CPR certification to all pharmacy students. The committee developed a service learning project by providing CPR training courses in the community. Participants in the course were required to complete an evaluation form at the conclusion of each training course. The CPR committee successfully certified more than 1,950 PharmD students and 240 community members from 1996 to 2009. Evaluations completed by participants were favorable, with 99% of all respondents (n = 351) rating the training course as either "excellent" or "good" in each of the categories evaluated. A PharmD student-directed committee successfully provided CPR training to other students and community members as a service learning experience.

    A very high-Q, low insertion loss resonator can be achieved by storing many overtone cycles of a lateral acoustic wave (i.e., Lamb wave) in a lithographically defined suspended membrane comprising a low damping resonator material, such as silicon carbide. The high-Q resonator can sets up a Fabry-Perot cavity in a low-damping resonator material using high-reflectivity acoustic end mirrors, which can comprise phononic crystals. The lateral overtone acoustic wave resonator can be electrically transduced by piezoelectric couplers. The resonator Q can be increased without increasing the impedance or insertion loss by storing many cycles or wavelengths in the high-Q resonator material, with much lower damping than the piezoelectric transducer material.

    2012-01-01

    This article describes the development and validation of the Core Competencies Scale (CCS) using Bok's (2006) competency framework for undergraduate education. The framework included: communication, critical thinking, character development, citizenship, diversity, global understanding, widening of interest, and career and vocational development. The sample comprised 70 college and university students. Results of analysis using Rasch rating scale modelling showed that there was strong empirical evidence on the validity of the measures in contents, structure, interpretation, generalizability, and response options of the CCS scale. The implication of having developed Rasch-based valid and dependable measures in this study for gauging the value added of college and university education to their students is that the feedback generated from CCS will enable evidence-based decision and policy making to be implemented and strategized. Further, program effectiveness can be measured and thus accountability on the achievement of the program objectives.

    The purpose of this study was to investigate factors that influence sexual intercourse among middle school students in South Korea. Using statistics from the 8th (2012) Korea Youth Risk Behavior Web-based Survey, hierarchical logistic regression analysis was conducted. The study sample comprised 37,297 middle school students aged primarily 12 to 15. The significant predictors of sexual intercourse were grade, ever smoking, ever drinking, habitual or purposeful drug use, economic status, weekly allowance, cohabitation with family, and type of school. The results suggest that intensified sex education is needed not only in the 1st grade of middle school, but also in the upper grades of elementary school. Sexual health interventions for high-risk groups may be needed, given the factors predicting sexual intercourse.

    2007-12-01

    To estimate correlations for scores on a student anti-intellectualism scale with scores on a measure of political conservatism, 235 students were given a survey containing a student anti-intellectualism scale, a political conservatism scale, and a demographics questionnaire identifying the participants' sex, college classification, ethnicity, political party affiliation, and self-described political ideology. The political conservatism scale contained two factors, Religiosity and Economic Conservatism, both of which were scored separately in addition to an overall Conservatism score. Students' Anti-intellectualism scores were correlated with Political Conservatism scores (r = .37, p < .01), with Religiosity scores (r = .42, p < .01), and with Economic Conservatism scores (r = .17, p < .05). An analysis of variance indicated a significant difference in students' Anti-intellectualism scores based on college classification (F4,233 = 2.27, p < .04). Specifically, freshman had significantly higher scores than graduate students.

    Boyd-Turner, Danni; Bell, Elaine; Russell, Alison

    2016-01-01

    This paper explores how the student placement experience may influence employment choices in the context of paediatric nursing. A qualitative research methodology was used. Data was collected using semi structured interviews at a tertiary teaching hospital. The sample group comprised of six newly qualified nurses who had completed their Bachelor of Nursing less than 12 months before the interview. They had completed at least one clinical placement at the site of data collection in their 2nd or 3rd year of undergraduate nursing studies. The main themes contributing to the student nurse experience within the context of paediatric nursing included the wish to work with children, a job being available, support during clinical placements and assistance with future career planning while on placement. The support experienced by student nurses during their clinical placement was seen to have a very positive influence on their future employment choices. Group de-briefing to support mutual understanding and sharing was seen to be a highly positive aspect of a clinical placement. Also how students were treated by clinical staff was a key factor that influenced future employment choices. Copyright © 2015 Elsevier Ltd. All rights reserved.

    The Utrecht Work Engagement Scale for Students has been used internationally to assess students' academic engagement, but it has not been analyzed via item response theory. The purpose of this study was to conduct an item response theory analysis of the Japanese version of the Utrecht Work Engagement Scale for Students translated by authors. Using a two-parameter model and Samejima's graded response model, difficulty and discrimination parameters were estimated after confirming the factor structure of the scale. The 14 items on the scale were analyzed with a sample of 3214 university and college students majoring medical science, nursing, or natural science in Japan. The preliminary parameter estimation was conducted with the two parameter model, and indicated that three items should be removed because there were outlier parameters. Final parameter estimation was conducted using the survived 11 items, and indicated that all difficulty and discrimination parameters were acceptable. The test information curve suggested that the scale better assesses higher engagement than average engagement. The estimated parameters provide a basis for future comparative studies. The results also suggested that a 7-point Likert scale is too broad; thus, the scaling should be modified to fewer graded scaling structure.

    American Indian/Alaska Natives comprise a small portion of the general college student population, but often have the poorest health and wellness, as well as the highest dropout rates compared to any other race or ethnicity. Despite the well-documented issues this group faces in higher education, they are often ignored in studies due to their status as the minority within the minority, comprising only 0.8% of all college students in the US. This study examines the differences in college students' overall ratings of health across racial and ethnic groups, focusing specifically on the health and wellness of AI/AN students compared to their counterparts. This paper also investigates the physical health issues students experienced in the past 12 months and the health issues' impact on their academic achievement. Results showed that AI/AN students reported the lowest overall health ratings and the most health issues in the past year.

    Full Text Available Background: According to the World Health Organization viewpoint, social well-being is an important dimension of health along with physical and mental aspects. Evaluation of social well-being is necessary in students, especially in medical sciences students due to future responsibility as health care professionals. The present study attempted to investigate the level of social well-being, five domains of it (like actualization, integration, contribution, and some related factors in the school of nursing and midwifery students. Methods: This cross-sectional study was carried out between Julys to December 2015 and comprised 346 students in the school of nursing and midwifery in Shiraz University of Medical Sciences, Shiraz, Iran. Social well-being, socio-demographic status and physical activity were measured by valid questionnaires. Univariate linear regression analysis, multiple imputation method, ANOVA and independent sample t-test were used as different statistical methods. The P values less than 0.05 were considered as statistically significant. Results: The mean score of social well-being was 50. The minimum and maximum scores of social well-being were 20 to 100. Married students had higher social well-being than single students in univariate linear regression (Beta: 2.111, 95% CI: (0.387 to 3.738, P=0.017. Also, social integration had higher scores in married students (P=0.015. Social actualization was higher in male students (P=0.015; on the other hand, social contribution was higher in female students (P=0.026. Conclusion: The results of our study showed that social well-being status of students in this research was not satisfactory. Designing and conducting programs for promotion of social well-being, for example preparing facilities for marriage of students, can be helpful. Evaluation of social well-being in students of other schools with multicenter studies seems to be useful.

    2013-01-01

    Full Text Available This study investigated the impact of a designed web-based learning module on Year 12 students’ learning of argumentative writing. The module known as WebQuest Learning Module or WebQLM comprises four units of learning. The subjects were 68 Year 12 Arts Stream students in an urban school in Penang. The main objective of this study was to investigate the effect of WebQLM on students’ performance in argumentative writing as well as students’ responses towards the integration of this web technology in the ESL classroom. The paired-samples T-Test revealed significant improvement in students’ argumentative writing performance. Findings from the questionnaire and group interviews showed students generally responded positively towards the use of WebQLM in argumentative writing instruction. This study has brought to light the importance of integrating web-based learning tasks in the classroom. The credibility of the teacher in web-based instruction depends very much on the roles he or she plays in designing, scaffolding, facilitating and aspiring students towards a better learning culture. Implications on the teaching and learning of writing in an ESL context, especially for learners in the contemporary digital culture, can be drawn from the findings.

    Social networking sites (SNSs) can be beneficial tools for users to gain social capital. Although social capital consists of emotional and informational resources accumulated through interactions with strong or weak social network ties, the existing literature largely ignores attachment style in this context. This study employed attachment theory to explore individuals' attachment orientations toward Facebook usage and toward online and offline social capital. A university student sample (study 1) and a representative national sample (study 2) showed consistent results. Secure attachment was positively associated with online bonding and bridging capital and offline bridging capital. Additionally, secure attachment had an indirect effect on all capital through Facebook time. Avoidant attachment was negatively associated with online bonding capital. Anxious-ambivalent attachment had a direct association with online bonding capital and an indirect effect on all capital through Facebook. Interaction frequency with good friends on Facebook positively predicted all online and offline capital, whereas interaction frequency with average friends on Facebook positively predicted online bridging capital. Interaction frequency with acquaintances on Facebook was negatively associated with offline bonding capital. The study concludes that attachment style is a significant factor in guiding social orientation toward Facebook connections with different ties and influences online social capital. The study extends attachment theory among university students to a national sample to provide more generalizable evidence for the current literature. Additionally, this study extends attachment theory to the SNS setting with a nuanced examination of types of Facebook friends after controlling extraversion. Implications for future research are discussed.

    Consistency, quality, and duration of sleep are important determinants of health. We describe sleep patterns among demographically defined subgroups from the Youth Risk Behavior Surveillance System reported in 4 successive biennial representative samples of American high school students (2007 to 2013). Across the 4 waves of data collection, 6.2% to 7.7% of females and 8.0% to 9.4% of males reported obtaining 9 or more hours of sleep. Insufficient duration of sleep is pervasive among American high school students. Despite substantive public health implications, intervention research on this topic has received little attention.

    The study examined the prevalence of the co-occurrence of intimate partner violence (IPV) and child maltreatment (CM) to determine whether IPV is a factor associated with the latter. A total of 5,841 students from a representative sample of schools in Hong Kong were surveyed. The results show that the lifetime and preceding-year co-occurrence rates of IPV and CM were 12.3% and 3.6%, respectively. IPV and parents' use of psychological aggression and corporal punishment led to increased odds of physical violence. This study suggests a need for the comprehensive assessment of IPV and CM. © The Author(s) 2015.

    Research on the negative effects of student cynicism has been limited, especially regarding its relation to student burnout. This study examined the relations among student cynicism (policy cynicism, academic cynicism, social cynicism, and institutional cynicism) and student burnout, as evidenced by emotional exhaustion, depersonalization, and reduced personal accomplishment, in a sample of 276 Chinese undergraduates. Hierarchical multiple regressions showed that four aspects of student cynicism together explained substantial variance in student burnout. Policy cynicism was the strongest contributor to emotional exhaustion. Social cynicism was the primary contributor to depersonalization, and also to reduced personal accomplishment. Student cynicism overall had the strongest relationship with reduced sense of personal achievement. The findings outline the negative functional relations between student cynicism and student burnout.

    The aim of this study was to analyze the effect of the inclusion of video triggers in conventional face-to-face lectures on the final grades of dental students in an oral biology course. The study consisted of two groups of students taking the course in two academic years at a dental school in Saudi Arabia: group 1, 2013-14 (control); and group 2, 2014-15. The total sample comprised 163 students (n=163; group 1: 71 and group 2: 92). Group 1 received lectures without any videos, whereas group 2 received lectures that included two to three videos of one to five minutes in duration with triggering effect (a video was shown every 10-15 minutes into the lecture). The final examination grades of the students were accessed retrospectively, and the data were compared with a chi-square test. The results confirmed that a higher number of students who received video triggering during lectures (group 2) performed better than their counterparts who did not receive video triggers (group 1); the difference was statistically significant (pvideo triggers may offer an advantage over conventional methods and their inclusion in lectures can be a way to enhance students' learning.

    The aim of this study was to profile students undertaking placements at University Departments of Rural Health (UDRHs) and investigate factors affecting students' satisfaction and intention to enter rural practice. Cross-sectional survey comprising 21 core questions used by all UDRHs. Eleven UDRHs across Australia that support students' placements in regional, rural and remote locations. Medical, nursing and allied health students who participated in UDRH placements between July 2014 and November 2015 and completed the questionnaire. Key dependent variables were placement satisfaction and rural practice intention. Descriptive variables were age, gender, Aboriginal or Torres Strait Islander (ATSI) background, location of placement, healthcare discipline, year of study and type and length of placement. A total of 3328 students responded. The sample was predominantly female (79%), the mean age was 26.0 years and 1.8% identified as ATSI. Most placements (69%) were >2 but ≤12 weeks, 80% were in Modified Monash 3, 4 or 5 geographical locations. Public hospitals and community health made up 63% of placements. Students satisfied with their placement had 2.33 higher odds of rural practice intention. Those satisfied with Indigenous cultural training, workplace supervision, access to education resources and accommodation had higher odds of overall satisfaction and post-placement rural practice intention. The majority of students were highly satisfied with their placement and the support provided by rural clinicians and the UDRHs. UDRHs are well placed to provide health professional students with highly satisfactory placements that foster rural practice intention. © 2017 National Rural Health Alliance Inc.

    The Depression Anxiety Stress scale (DASS) is a widely used instrument for assessing mental health status, but the construct validity of the Chinese version of the test has not been demonstrated. The current study recruited three independent samples of Chinese participants to examine its reliability, factor structure, and utility in differentiating groups expected to show high and low scores on the scales. The first sample comprised 605 undergraduate student volunteers from Beijing, the second sample comprised 138 residents from the Sichuan Province who had experienced the 2008 earthquake there, and the third sample comprised 86 Beijing residents. Cronbach's alpha values in excess of 0.80 were found for all samples and all scales. Confirmatory factor analysis with the student sample supported a three-factor latent structure for the DASS (depression, anxiety, and stress). Substantially higher scores on all scales were found for the Sichuan earthquake sample compared with the Beijing resident's sample. Implications of these findings for the assessment of mental status using the DASS in China are discussed. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

    The aim of this study was to evaluate baccalaureate nursing students' attitudes toward menstruation, and to analyze the frequency of premenstrual syndrome (PMS) symptoms, as well as the relationship between attitudes toward menstruation and PMS symptoms. This cross-sectional study was carried out between February 15 and March 10, 2009, in Ankara Turkey. The study participants were 250 undergraduate nursing student volunteers. Data were collected using a demographic questionnaire, the validated Turkish version of the Menstrual Attitude Questionnaire (MAQ), and the validated Turkish Premenstrual Syndrome (PMS) Scale. Obtained data were analyzed using SPSS version 15.0. The average age of participants was 19.89 ± 1.43. The MAQ's five subscales' mean scores ranged from 2.67 ± 0.58 to 3.37 ± 0.52, indicating natural to moderate attitudes toward menstruation. The mean PMS score was 114.86 ± 35.15, indicating moderate PMS symptoms. PMS symptoms were detected in 36.4% of the nursing students. Thirty one percent of the students reported having dysmenorrhoea during every menstrual cycle. Students who had PMS symptoms scored significantly higher on the debilitation subscale and scored significantly lower on the denial subscale of the MAQ (p menstruation was considered to be a natural event by most of the nursing students. In addition, dysmenorrhea was found to be the most common menstrual problem and the rate of PMS was found lower than that found in previous researches conducted in Turkey.

    Alzheimer's disease is most common among the dementias and is characterized by gradual declines in functional and cognitive abilities. Caregivers including family members play a key role in providing critically needed care for these patients. This study compared the knowledge and attitudes of pre-healthcare and non-medical undergraduate students towards patients with Alzheimer's disease. A cross-sectional study was conducted involving quota sampling of 691 undergraduate students (369 pre-healthcare and 322 non-medical). A 28-item questionnaire was utilised comprising of closed-ended questions and some based on a scale rating. The students' knowledge of Alzheimer's disease was arranged into categories such as: 0 for no knowledge about Alzheimer's disease, 1 for very little knowledge about Alzheimer's disease, 2 for fair knowledge about Alzheimer's disease and 3 for great knowledge about Alzheimer's disease. The data was analysed using the computer software SPSS and the Chi squared test of independence was also used to determine which knowledge variables were independent of student's status. Overall, 40.01% of the students have great or fair knowledge of Alzheimer's disease, with that of pre-healthcare students being satisfactory (54.47%). Pre-healthcare students have a more positive attitude towards Alzheimer's disease and 82.2% of students wished to take advantage of predictive test for Alzheimer's disease. Age and genetics were identified as risk factors of the disease. Pre-healthcare students had greater understanding of Alzheimer's disease and depicted a more empathetic and caring attitude towards patients. This can be attributed mainly to their knowledge and exposure toward the disease.

    The goal of this study is to better understand the longitudinal cross-lagged associations between popularity, assessed through self-rating and peer nominations, and alcohol use among middle school students. The analytical sample comprises 1,835 sixth- to eighth-grade students who were initially recruited from three California middle schools and surveyed in the fall and spring semesters of 2 academic years. Students reported on their background characteristics, past-month alcohol use, and perceived popularity. Additionally, students provided school-based friendship nominations, which were used to calculate peer-nominated popularity. A cross-lagged regression approach within a structural equation modeling framework was used to examine the longitudinal relationship between popularity (self-rated and peer-nominated) and alcohol use. There was a statistically significant (p = .024) association between peer-nominated popularity and the probability of alcohol consumption at the subsequent survey, but not vice versa. Our results suggest that in a scenario where 8% of students are past-month drinkers, each increase of five friendship nominations is associated with a 30% greater risk of being a current drinker at the next wave. We found no evidence of longitudinal associations between past-month alcohol consumption and self-rated popularity. Popularity is a risk factor for drinking during the middle school years, with peer-nominated popularity being more predictive of use than self-perceptions of popularity. To inform alcohol prevention efforts for middle school students, additional research is needed to better understand why adolescents with a larger number of school-based friendship ties are more inclined to drink.

    Achievement in school is crucial for students to be able to pursue successful careers and lead happy lives in the future. Although many psychological attributes have been found to be associated with academic performance, the neural substrates of academic performance remain largely unknown. Here, we investigated the relationship between brain structure and academic performance in a large sample of high school students via structural magnetic resonance imaging (S-MRI) using voxel-based morphometry (VBM) approach. The whole-brain regression analyses showed that higher academic performance was related to greater regional gray matter density (rGMD) of the left dorsolateral prefrontal cortex (DLPFC), which is considered a neural center at the intersection of cognitive and non-cognitive functions. Furthermore, mediation analyses suggested that general intelligence partially mediated the impact of the left DLPFC density on academic performance. These results persisted even after adjusting for the effect of family socioeconomic status (SES). In short, our findings reveal a potential neuroanatomical marker for academic performance and highlight the role of general intelligence in explaining the relationship between brain structure and academic performance.

    2017-12-01

    Student well-being has mostly been studied as an individual phenomenon with little research investigating how the well-being of one's classmates could influence a student's well-being. The aim of the current study was to examine how the aggregate well-being of students who comprise a class could predict students' subsequent well-being (Time 2 well-being) after controlling for the effects of prior well-being (Time 1 well-being) as well as key demographic variables such as gender and age. Two studies among Filipino secondary school students were conducted. In Study 1, 788 students from 21 classes participated; in Study 2, 404 students from 10 classes participated. For Study 1, questionnaires assessing students' life satisfaction, positive affect and negative affect were administered twice seven months apart. For Study 2, the well-being questionnaires were administered twice, three months apart. Hierarchical linear modeling was used with level 1 (Time 1 individual well-being, gender, and age) and level 2 (class well-being) predictors. Results across the two studies provided converging lines of evidence: students who were in classes with higher levels of life satisfaction and positive affect were also more likely to have higher life satisfaction and positive affect at Time 2. The study indicated that the well-being of a student partly depends on the well-being of their classmates providing evidence for the social contagion of well-being in the classroom context.

    2018-03-27

    Introduction: In the United Arab Emirates, smoking prevalence has increased in both sexes, especially among young adults. Various factors have led to this catastrophe; examples include coverage on TV and social media, as well as market availability. One major influence is smoking by parents and peers. A lot of students may start smoking because of the behavior of their family and friends, and therefore it is necessary to quantify adverse contributions. The aim of this project was to study to what degree parents and peers smoking habits may impact on smoking behavior of students at the University of Sharjah. Methods: This cross-sectional observational study with a non-probability convenient type of sampling, was conducted with university students aged 18 to 23. Information was collected using a self-administered questionnaire, comprising 23 questions, developed by ourselves. Results: A total of 400 University of Sharjah students (50% males and 50% females) were included.Some 15.8% of the smoking students had smoking parents, and 17.1% of them had smoking peers. The respective figures were 22.2% and 21.7% for males and 10% and 7.8% for females. Conclusions: Peers had a stronger impact than parents and both parents and peers had greater influence on males than on females. Interestingly, almost 80% of the smoking students did not have smoking parents or peers, which leaves the question unanswered of why they started smoking in the first place. Actions at a societal level should be taken into consideration to prevent smoking and thus help create a non-smoking generation. Creative Commons Attribution License

    This study aimed to examine the effects of 14 months of military training comprising cold winter conditions on neurosensory and vascular function in the hands and feet. Military conscripts (N=54) were assessed with quantitative sensory testing comprising touch, temperature, and vibration perception thresholds and finger systolic blood pressure (FSBP) after local cooling and a questionnaire on neurosensory and vascular symptoms at both baseline and follow-up. Ambient air temperature was recorded with body worn temperature loggers. The subjects showed reduced sensitivity to perception of touch, warmth, cold and vibrations in both the hands and feet except from vibrotactile perception in digit two of the right hand (right dig 2). Cold sensations, white fingers, and pain/discomfort when exposed to cold as well as pain increased in both prevalence and severity. There were no statistically significant changes in FSBP after local cooling. Fourteen months of winter military training comprising cold winter conditions reduced sensation from touch, warmth, cold, and vibrotactile stimulus in both hands and feet and increased the severity and prevalence of symptoms and pain. The vascular function in the hands, measured by FSBP after local cooling, was not affected.

  11. Teacher students' dilemmas when teaching science through inquiry

    Science.gov (United States)

    Krämer, Philipp; Nessler, Stefan H.; Schlüter, Kirsten

    2015-09-01

    Background: Inquiry-based science education (IBSE) is suitable to teach scientific contents as well as to foster scientific skills. Similar conclusions are drawn by studies with respect to scientific literacy, motivational aspects, vocabulary knowledge, conceptual understandings, critical thinking, and attitudes toward science. Nevertheless, IBSE is rarely adopted in schools. Often barriers for teachers account for this lack, with the result that even good teachers struggle to teach science as inquiry. More importantly, studies indicate that several barriers and constraints could be ascribed to problems teacher students have at the university stage. Purpose: The purpose of this explorative investigation is to examine the problems teacher students have when teaching science through inquiry. In order to draw a holistic picture of these problems, we identified problems from three different points of view leading to the research question: What problems regarding IBSE do teacher students have from an objective, a subjective, and a self-reflective perspective? Design & method: Using video analysis and observation tools as well as qualitative content analysis and open questionnaires we identified problems from each perspective. Results: The objectively stated problems comprise the lack of essential features of IBSE especially concerning 'Supporting pupils' own investigations' and 'Guiding analysis and conclusions.' The subjectively perceived problems comprise concerns about 'Teachers' abilities' and 'Pupils' abilities,' 'Differentiated instruction' and institutional frame 'Conditions' while the self-reflectively noticed problems mainly comprise concerns about 'Allowing inquiry,' 'Instructional Aspects,' and 'Pupils' behavior.' Conclusions: Each of the three different perspectives provides plenty of problems, partially overlapping, partially complementing one another, and partially revealing completely new problems. Consequently, teacher educators have to consider these

    2012-11-01

    The aim of this cross-sectional study was to evaluate the mental health of student teachers, to analyse the extent to which they feel prepared for their profession by the university curriculum and to investigate patterns of coping with occupational stress. A sample of 481 German student teachers was investigated using two standardised instruments: GHQ-12 (General Health Questionnaire) and AVEM (Arbeitsbezogenes Verhaltens- und Erlebensmuster), an occupational stress and coping questionnaire describing four patterns of work-related coping behaviour. In addition, we asked how well the student teachers felt that the curriculum prepared them for their profession. Forty-four per cent of the student teachers report impaired mental health in the second teacher training period, indicated by a GHQ value equal to or over the cut-off of four. The AVEM responses revealed more than 40% showing risk patterns (A or B) compared to only 26.3% displaying a healthy coping style (G), while 32.8% demonstrate an unambitious style (S). These GHQ values are inversely correlated with the extent to which student teachers feel prepared for their work by the university curriculum. Our data indicate a problematic stress level for student teachers in the second training phase (high exposure to health risks and unfavourable coping styles). Since teaching is clearly an extremely demanding job, it is vital that teacher training systems contribute towards protecting the health of teachers by focusing on fostering healthy personal attitudes and equipping young teachers with coping styles and skills that will better prepare them for the challenges facing them in their daily work. Self-care health management should also be part of the teacher training curriculum.

    The transition of young people from school to university has many health implications. Food choice at the university can differ because of childhood food consumption patterns, sex and the living arrangements. Food consumption may change especially if students are living away from home. We aimed to assess food consumption patterns among university students from four European countries and how they differ by their living arrangements. We analysed data from a cross-country survey assessing health and health behaviours of students. The sample comprised a total of 2402 first year undergraduate students from one university in each of the countries of Germany, Denmark, Poland and Bulgaria. Food consumption was assessed by means of a food frequency questionnaire with 9 food groups (indicators). Students' food consumption patterns differed across the countries. Frequent consumption of unhealthy items was common. Bulgarian students reported most often frequent consumption of sweets and cakes and snacks (e.g. chips and fast food). Polish students reported the least frequent consumption of vegetables and a low consumption of fruits. Across all countries except Bulgaria, men reported substantially more often frequent consumption of snacks than women. Students living at parental home consumed more fruit, vegetables, and meat than those who resided outside of their family home in all studied countries. There was more variation with regard to cakes and salads with more frequent consumption of cakes among Bulgarian female students and Danish male students and more frequent consumption of salads among Danish female students not living at parental home, compared to students from other countries. Nutrition habits of university students differed across countries and by sex. Students living at parental home displayed more healthy nutrition habits, with some exceptions.

    2011-11-01

    We model the performance of superhydrophobic surfaces comprised of randomly distributed roughness that resembles natural surfaces, or those produced via random deposition of hydrophobic particles. Such a fabrication method is far less expensive than ordered-microstructured fabrication. The present numerical simulations are aimed at improving our understanding of the drag reduction effect and the stability of the air-water interface in terms of the microstructure parameters. For comparison and validation, we have also simulated the flow over superhydrophobic surfaces made up of aligned or staggered microposts for channel flows as well as streamwise or spanwise ridge configurations for pipe flows. The present results are compared with other theoretical and experimental studies. The numerical simulations indicate that the random distribution of surface roughness has a favorable effect on drag reduction, as long as the gas fraction is kept the same. The stability of the meniscus, however, is strongly influenced by the average spacing between the roughness peaks, which needs to be carefully examined before a surface can be recommended for fabrication. Financial support from DARPA, contract number W91CRB-10-1-0003, is acknowledged.

    2015-12-01

    Over the course of the next decade or more, many thousands of geological samples will be collected and analyzed in a variety of ways by researchers at the Jet Propulsion Laboratory (California Institute of Technology) in order to facilitate discovery and contextualize observations made of Mars rocks both in situ and here on Earth if samples are eventually returned. Integration of data from multiple analyses of samples including petrography, thin section and SEM imaging, isotope and organic geochemistry, XRF, XRD, and Raman spectrometry is a challenge and a potential obstacle to discoveries that require supporting lines of evidence. We report the development of a web-accessible repository, the Sample Data Library (SDL) for the sample-based data that are generated by the laboratories and instruments that comprise JPL's Center for Analysis of Returned Samples (CARS) in order to facilitate collaborative interpretation of potential biosignatures in Mars-analog geological samples. The SDL is constructed using low-cost, open-standards-based Amazon Web Services (AWS), including web-accessible storage, relational data base services, and a virtual web server. The data structure is sample-centered with a shared registry for assigning unique identifiers to all samples including International Geo-Sample Numbers.

    Full Text Available The main aim of this study was to examine the differences in motivation to participate in sport activities among sports students from three different countries. On a sample of 390 sports students from Slovenia, Croatia and Germany we studied what motivates an interest in being sports active. The sample was stratified across the choice to attend table tennis lessons at all three institutions and all students have completed the Participation Motivation Questionnaire (PMQ. The results revealed that the latent structure of the types of sports students' motives consisted of six factors (sport action with friend, popularity, fitness & health, social status, sports events, relaxation through sports. We also found significant sex differences in motivation to participate in sport activities for all sports students from the three different countries. We did not find relevant age-based differences among the students, and this is the only initial hypothesis that we can reject.

    1998-01-01

    The present invention provides a device for accurately sampling molten salts to which various kinds of metals in a molten salt storage tank are mixed for analyzing them during a spent fuel dry type reprocessing. Namely, the device comprises a sampling tube having an opened lower end to be inserted into the radioactive molten salts stored in a tank and keeps reduced pressure from the upper end, and a pressure reducing pipeline having one end connected to the sampling tube and other end connected to an evacuating pump. In this device, the top end of the sampling tube is inserted to a position for sampling the radioactive molten salts (molten salts). The pressure inside the evacuating pipeline connected to the upper portion of the sampling tube is reduced for a while. In this case, the inside of the pressure reducing pipeline is previously evacuated by the evacuating pump so as to keep a predetermined pressure. Since the pressure in the sampling tube is lowered, molten salts are inserted into the sampling tube, the sampling tube is withdrawn, and the molten salts flown in the sampling tube are analyzed.

    One provides nanocrystalline diamond material that comprises a plurality of substantially ordered diamond crystallites that are sized no larger than about 10 nanometers. One then disposes a non-diamond component within the nanocrystalline diamond material. By one approach this non-diamond component comprises an electrical conductor that is formed at the grain boundaries that separate the diamond crystallites from one another. The resultant nanowire is then able to exhibit a desired increase with respect to its ability to conduct electricity while also preserving the thermal conductivity behavior of the nanocrystalline diamond material.

    To investigate medical students' career choice motivation and its relationship with their academic interest and performance. We conducted a cross-sectional study in a sample (n=207) of medical students at a private medical school in Korea, stratified by year of medical course. Data about participant demographics, career choice motivation and academic interest were collected using a self-report questionnaire. The item on career choice motivation enquired about the respondents' main reason for applying for medical school among 8 possible response options, which comprised two components of career choice motivation: intrinsic and extrinsic. The participants' levels of academic interest were measured in a Likert-type question. Participants' academic interest and Grade Point Averages (GPAs) were compared across the groups of different career motivations along with analyses of their admission scores for baseline comparisons. A total of 195 students completed the questionnaire (94%response rate). Seventy-four percent, (n=145; the intrinsic group) of the participants chose reasons related to intrinsic motivation, 22% (n=42; the extrinsic group) chose reasons pertaining to extrinsic motivation, and 4% (n = 8) chose other reasons for applying to medical school. The intrinsic group outperformed the extrinsic group in their GPAs, although their prior academic achievements did not differ significantly. The intrinsic group showed significantly higher levels of academic interest and also performed better in the admission interviews. Our study illustrates differences in medical students' academic interest and performance across career choice motivations. Further research is warranted to establish the predictive power of medical students' career choice motivation and academic interest on their academic performance.

    Fundamental knowledge of microscopic anatomy and pathology has always been an essential part in medical education. The traditional didactic concept comprises theoretical and practical lessons using a light microscope and glass slides. High-speed Internet connections and technical improvement in whole-slide digital microscopy (commonly termed "virtual microscopy") provide a new and attractive approach for both teachers and students. High picture quality and unlimited temporal and spatial availability of histology samples from different fields are key advantages of web-based digital microscopy. In this report we discuss the technical requirements, system efficiency, optical resolution and didactic concept. Furthermore, we present a review of the experience gained in the course of one year based on an analysis of student acceptance. Three groups with a total of 192 students between the 3rd and 5th year of medical studies attending the practical courses of general and advanced histopathology had access to both glass-mounted and digitalized slides. Prior to exams, students were asked to answer an anonymous questionnaire. The results of the study reflect the high acceptance and intensive use of the web-based digital histology by students, thus encouraging the development of further Web-based learning strategies for the teaching of histology and pathology. 2010 Elsevier GmbH.

    Full Text Available The importance of the use of diversified literature for enhancing speech culture in school is recognized and highlighted in Serbian language teaching. In order to find out what selections of literature junior students make and whether free choice of literature results in acquisition of verbal contents and development of verbal expressiveness, we examined the retelling of a previously read text, since this form of verbal behavior is predominantly used for developing students’ verbal expressiveness in primary school. The study was conducted on a sample comprising the first, second, third, and fourth grade students of an urban primary school (30 respondents in each group, total = 120. The aim was to register, during the students’ retelling, the number and the production of newly acquired words and the correctness of the sentences used. The linguistic material used in the research contained fairy tales, fables, short stories and books that children had spontaneously selected. The analysis showed that books are a useful tool for enhancing both vocabulary expansion and elaboration of sentence structures. When analyzing the results of this type the distinction must be made between the attainment of students who only reproduce expressions and structures and those who productively use new words and structures. .

    Psychotic disorders, as well as psychotic-like experiences and substance use, have been found to be associated. The main goal of the present study was to analyse the relationship between psychoticlike experiences and substance use in college students. The simple comprised a total of 660 participants (M = 20.3 years, SD = 2.6). The results showed that 96% of the sample reported some delusional experience, while 20.3% reported at least one positive psychotic-like experience. Some substance use was reported by 41.1% of the sample, differing in terms of gender. Substance users reported more psychoticlike experiences than non-users, especially in the positive dimension. Also, alcohol consumption predicted in most cases extreme scores on measures of delusional ideation and psychotic experiences. The association between these two variables showed a differentiated pattern, with a stronger relationship between substance use and cognitive-perceptual psychotic-like experiences. To some extent, these findings support the dimensional models of the psychosis phenotype and contribute a better understanding of the links between psychoticlike experiences and substance use in young adults. Future studies should further explore the role of different risk factors for psychotic disorders and include models of the gene-environment interaction.

  19. Social and structural vulnerability as a barrier in HIV and/or AIDS communication campaigns: Perceptions of undergraduate students at a South African tertiary institution

    Full Text Available The multicultural nature of a higher academic institution comprising students from different backgrounds can either negatively or positively influence student behaviour. Students might engage in high-risk practices, which in turn can make them vulnerable to HIV infection. Higher academic institutions are then tasked with finding strategies that can help to reduce this risk and vulnerability to HIV and/or AIDS. However, there are many issues and barriers, both from the institution and students, which can impede the success of any communication strategy. The University of the Free State’s main campus was selected for this study. A sample of 402 students from a total of 17 591 undergraduate students participated in the study. A structured questionnaire was randomly distributed to the undergraduate students. The sample was compiled across all faculties, as well as on campus and off campus. A transact walk on campus with an observation checklist was also used for triangulation purposes. The observation checklist helped to collect data on the visibility of male and female condoms in toilet facilities, and HIV and/or AIDS information on noticeboards, bins, stationery, billboards, etc. The main finding indicated that students were not knowledgeable about HIV and/or AIDS campaigns rolled out on campus. To support this, the observational transact walk results indicated that there were no visible campaigns on campus. Also, problems with existing communication and organisational barriers were found not only with the students but also with the implementation office. This study recommends that the university needs to engage with the students by identifying the root cause of their vulnerability. The university should explore and make use of all the available resources for a successful intervention, thereby building students’ resilience in preventing HIV infection.

    Although the use of simulation to teach the sampling distribution of the mean is meant to provide students with sound conceptual understanding, it may lead them astray. We discuss a misunderstanding that can be introduced or reinforced when students who intuitively understand that "bigger samples are better" conduct a simulation to…
