    The aim of this work was to adapt the Group Environment Questionnaire (GEQ) to Spanish. Judgmental procedures were used to assess the linguistic and cultural equivalence of the versions. Psychometric procedures were used in the operational phase of the study. The normative sample comprised 924 sportsmen/sportswomen from 75 teams. The GEQ scale showed suitable indexes of internal consistency and a bidimensional structure based on two factors of the cohesion model, the Task component and the Social component. In addition, a positive relation between team-performance and the Task component of team cohesion was observed. Overall, the results supported the Spanish version of the GEQ.

    Given the significance of monitoring the critical environmental factors that facilitate athlete performance, this two-phase research aimed to validate and refine the revised talent development environment questionnaire (TDEQ). The TDEQ is a multidimensional self-report scale that assesses talented athletes' environmental experiences. Study 1 (the first phase) involved the examination of the revised TDEQ through an exploratory factor analysis (n = 363). This exploratory investigation identified a 28-item five-factor structure (i.e., TDEQ-5) with adequate internal consistency. Study 2 (the second phase) examined the factorial structure of the TDEQ-5, including convergent validity, discriminant validity, and group invariance (i.e., gender and sports type). The second phase was carried out with 496 talented athletes through the application of confirmatory factor analyses and multigroup invariance tests. The results supported the convergent validity, discriminant validity, and group invariance of the TDEQ-5. In conclusion, the TDEQ-5 with 25 items appears to be a reliable and valid scale for use in talent development environments.

    It is clear that high class expertise and effective practice exists within many talent development environments across the world. However, there is also a general consensus that widespread evidence-based policy and practice is lacking. As such, it is crucial to develop solutions which can facilitate effective dissemination of knowledge and promotion of evidence-based talent development systems. While the Talent Development Environment Questionnaire (Martindale et al., 2010 ) provides a method through which this could be facilitated, its ecological validity has remained untested. As such, this study aimed to investigate the real world applicability of the questionnaire through discriminant function analysis. Athletes across ten distinct regional squads and academies were identified and separated into two broad levels, 'higher quality' (n = 48) and 'lower quality' (n = 51) environments, based on their process quality and productivity. Results revealed that the Talent Development Environment Questionnaire was able to discriminate with 77.8% accuracy. Furthermore, in addition to the questionnaire as a whole, two individual features, 'quality preparation' (P < 0.01) and 'understanding the athlete' (P < 0.01), were found to be significant discriminators. In conclusion, the results indicate robust structural properties and sound ecological validity, allowing the questionnaire to be used with more confidence in applied and research settings.

    As sporting challenge at the elite level becomes ever harder, maximizing effectiveness of the talent development pathway is crucial. Reflecting this need, this paper describes the development of the Talent Development Environment Questionnaire, which has been designed to facilitate the development of sporting potential to world-class standard. The questionnaire measures the experiences of developing athletes in relation to empirically identified "key features" of effective talent development environments. The first phase involved the generation of questionnaire items with clear content and face validity. The second phase explored the factor structure and reliability. This was carried out with 590 developing athletes through application of exploratory factor analysis with oblique rotation, principal axis factoring extraction and cronbach alpha tests. This yielded a 59-item, seven-factor structure with good internal consistency (0.616-0.978). The Talent Development Environment Questionnaire appears to be a promising psychometric instrument that can potentially be useful for education and formative review in applied settings, and as a measurement tool in talent development research.

    The purpose of the current study was to initiate the development of a psychometrically sound measure of cohesion for youth sport groups. A series of projects were undertaken in a four-phase research program. The initial phase was designed to garner an understanding of how youth sport group members perceived the concept of cohesion through focus groups (n = 56), open-ended questionnaires (n = 280), and a literature review. In Phase 2, information from the initial projects was used in the development of 142 potential items and content validity was assessed. In Phase 3, 227 participants completed a revised 87-item questionnaire. Principal components analyses further reduced the number of items to 17 and suggested a two-factor structure (i.e., task and social cohesion dimensions). Finally, support for the factorial validity of the resultant questionnaire was provided through confirmatory factor analyses with an independent sample (n = 352) in Phase 4. The final version of the questionnaire contains 16 items that assess task and social cohesion in addition to 2 negatively worded spurious items. Specific issues related to assessing youth perceptions of cohesion are discussed and future research directions are suggested.

    With 1 185 pieces of questionnaire, it is found that in China, people take fresh air, odor, etc. , as well as indoor air temperature, humidity, as the most important indoor air parameters. It is also found that there is a significant sensitivity difference in indoor environment between southerners and northerners in China. People from different regions have different demands for their working and living environment. Therefore, as a good design of air conditioning system, it is strongly recommended that the different demands of people from different regions should be taken into consideration.

    Individual interviews are often considered to be the gold standard for researchers to understand how people think about phenomena. However, conducting and analyzing interviews is very time consuming. This paper presents the Group Administered Interactive Questionnaire (GAIQ) as an alternative to individual interviews and discusses the pros and cons of each data collection method. Use of GAIQ will be discussed in the context of a study that seeks to understand teaching assistants' reasons for the design of problem solutions for introductory physics.

    Clinical learning is a vital component of nurse education and assessing student's experiences can provide useful insights for development. Whilst most research in this area has focused on the acute setting little attention has been given to all pre-registration nurses' experience across the clinical placements arenas. To examine of pre-registration nursing students (first, second and third year) assessment of their actual experiences of their most recent clinical learning clinical learning experience. A cross sectional survey involving a descriptive online anonymous questionnaire based on the clinical learning environment inventory tool. One higher education institution in the United Kingdom. Nursing students (n=147) enrolled in an undergraduate nursing degree. This questionnaire included demographic questions and the Clinical Learning Environment Inventory (CLEI) a 42 item tool measuring student's satisfaction with clinical placement. SPPS version 22 was employed to analyse data with descriptive and inferential statistics. Overall students were satisfied with their clinical learning experience across all placement areas. This was linked to the 6 constructs of the clinical learning environment inventory; personalization, innovation, individualization, task orientation, involvement, satisfaction. Significant differences in student experience were noted between age groups and student year but there was no difference noted between placement type, age and gender. Nursing students had a positive perception of their clinical learning experience, although there remains room for improvement. Enabling a greater understanding of students' perspective on the quality of clinical education is important for nursing education and future research. Copyright © 2017. Published by Elsevier Ltd.

    The Sport Emotion Questionnaire (SEQ) (Jones, M. V., Lane, A. M., Bray, S. R., Uphill, M., & Catlin, J. (2005). Development and validation of the SEQ. Journal of Sport and Exercise Psychology, 27, 407-431) was developed and initially validated to assess sport performers' pre-competitive emotions. The purpose of this study was to test the factor structure of the SEQ in a different environment (viz. organisational) and at a different time point (viz. the past month). A further aim was to examine if the SEQ was invariant across different groups of sport performers. A diverse sample of athletes (n = 1277) completed the questionnaire. Fit indices from confirmatory factor analyses provided partial support for the hypothesised measurement model, with equal or better fit demonstrated than evident in initial validation. The comparative fit index values were above acceptable guidelines for all factors at subscale level. Evidence was also found for the invariance of the SEQ across different groups. Overall, the findings support the reliability and validity of the SEQ as a measure of the emotions experienced by sport performers in an organisational environment during the past month.

    2017-01-01

    This study aimed to translate the Talent Development Environment Questionnaire into Spanish and provide an initial validation. A recommended methodology for translation and cultural adaptation of questionnaires was applied. Once this had been completed, three hundred and thirty-two young athletes completed the Talent Development Environment Questionnaire. The results revealed that the five factor solution Talent Development Environment Questionnaire was confirmed. With the exclusion of one item due to low factor loading, the Talent Development Environment Questionnaire-5 had robust statistical support for its factor structure (χ2 (df = 305) = 499.64, p<0.01, CFI = 0.90, RMSEA = 0.045, SRMR = 0.055). It also demonstrated adequate convergent and discriminant validity. While the internal reliability was lower than in previous studies, it revealed acceptable levels. Specifically the overall 27 item Talent Development Environment Questionnaire-5 had a Cronbach α score of .877, and the reliability scores for individual factors 1-5 were .622; .761; .658; .605; .602 respectively. As such, it is recommended that the Spanish Talent Development Environment Questionnaire-5 can be used with confidence in Spain in both applied and research settings.

    Nowadays, ubiquitous healthcare is of utmost importance in the patient-centric model. Furthermore, the personalization of ubiquitous healthcare services plays a very important role to make the patient-centric model a reality. The personalization of the ubiquitous healthcare services is based on the profiles of the entities participating in these services. In this paper, we propose a group profile management system in a ubiquitous healthcare environment. The proposed system is responsible for the dynamic creation of a group profile and its management.

    It is generally accepted that active mobility, mainly walking and cycling, contributes to people’s physical and mental health. One of the current challenges is to improve our understanding of this type of behaviour. This study aims to identify factors from the daily-life environment that may be related to active mobility behaviours, in order to design a new questionnaire for a quantitative study of a large adult population. The new questionnaire obtained through this pilot study combines information from interviews with existing questionnaires materials in order to introduce new factors while retaining the factors already assessed. This approach comprises three stages. The first was a content analysis (Reinert method) of interviews with a sample of participants about daily living activities as well as mobility. This stage led to a typology of factors suggested by interviews. The second was a scoping review of the literature in order to identify the active mobility questionnaires currently used in international literature. The last stage was a cross-tabulation of the factors resulting from the written interviews and the questionnaires. A table of the inter-relationships between the interview-based typology and the questionnaires shows discrepancies between factors considered by the existing questionnaires, and factors coming from individual interviews. Independent factors which were ignored in or absent from the questionnaires are the housing situation within the urban structure, overall consideration of the activity space beyond the limits of the residential neighbourhood, the perception of all the transportation modes, and the time scheduling impacting the modes actually used. Our new questionnaire integrates both the usual factors and the new factors that may be related to active mobility behaviours. PMID:28052086

    The aim of the study was the validation and adaptation of the ORTO-15 Questionnaire in the group of the Polish schoolgirls and schoolboys. The study included 399 participants (15-21 years old), all of them high school students in the city of Sosnowiec. The ORTO-15 is a tool created in Italy by L.M. Donini, comprising of 15 items describing intensification of orthorexia risk (population diagnosis). The validation procedure incorporated three basic methods to be applied in the reliability analysis - the comparison of double tests with the same method, the statistical properties analysis of test items as well as analysis of the relation of test items with the general test result. Moreover, the compliance of the ORTO-15 Questionnaire results with other questionnaire focused on eating habits (EAT-26) was studied. The reliability analysis of the ORTO-15 Questionnaire based on repeatability of the responses presents a very good (kappa: 0.81 - 1.00 for 5 items) and a good repeatability (kappa: 0.61 - 0.80 for 10 items). The reliability analysis based on the value of the Cronbach's α reached a satisfactory level (0.7 - 0.9). A full agreement of in the occurrence of orthorexia risk and the risk of eating disorders concerned 47.2% (Kappa = 0.04; 95% CI: 0.004 - 0.09) for the Ortho-40 and 88.2% (Kappa = 0.32; 95% CI: 0.17 - 0.47) for the Ortho-35. The ORTO-15 questionnaire is a reliable tool to identify the risk of ON in population studies in the group of urban youth aged 15 - 21.

    The Somatoform Dissociation Questionnaire is a self-report questionnaire that has proven to be a reliable and valid instrument. The objectives of this study were to validate the Portuguese version and to determine its capability to distinguish patients with dissociative disorders from others with psychopathological disorders. 234 patients answered the translated version of Somatoform Dissociation Questionnaire. The Portuguese Dissociative Disorders Interview Schedule was used to validate clinical diagnosis. Patients with dissociative disorder (n = 113) were compared to a control group of 121 patients with various anxiety and depression disorders. Reliability measured by Cronbach's a was 0.88. The best performance of the Portuguese form was at a cut-off point of 35, which distinguishes between dissociative disorder and neurotic disorders with a good diagnostic efficacy (sensitivity = 0.73). The somatoform dissociation was significantly more frequent in dissociative disorder patients, conversion disorder patients and post-traumatic stress disorder patients. These findings suggest that dissociative disorders can be differentiated from other psychiatric disorders through somatoform dissociation. The Portuguese version of the Somatoform Dissociation Questionnaire has fine psychometric features that sustain its cross-cultural validity.

    Full Text Available A poor acoustic environment in a school is known to negatively affect pupils′ learning and achievement. This paper presents the design and findings of an online questionnaire survey of 11-16 year olds′ impressions of their school′s acoustic environment. A total of 2588 English secondary school pupils responded to the questionnaire. Factor analysis was used to identify variables which best characterized pupils′ impressions of their school′s acoustic environment. Four factors, corresponding to ease of hearing in school spaces, sensitivity to noise, the consequences of noise in the classroom, and annoyance to intermittent noise, accounted for 43% of the total variance in pupils′ responses to the questionnaire. Analysis of the responses on these factors showed that pupils who reported additional learning needs such as hearing impairment, speaking English as an additional language or receiving learning support reported being significantly more affected by poor school acoustics than pupils reporting no additional learning needs. Older pupils were significantly more sensitive to noise annoyance and to the consequences of poor acoustical conditions on their learning and behaviour than younger pupils. Pupils attending suburban schools featuring cellular classrooms that were not exposed to a nearby noise sources were more positive about their school acoustics than pupils at schools with open plan classroom designs or attending schools that were exposed to external noise sources. The study demonstrates that adolescents are reliable judges of their school′s acoustic environment, and have insight into the disruption to teaching and learning caused by poor listening conditions. Furthermore, pupils with additional learning needs are more at risk from the negative effects of poor school acoustics.

    There is a lack of validated and reliable instruments on perception of the food environment, in particular for rural environments. We estimated the test-retest reliability of a questionnaire assessing perceptions of the food environment. A total of 101 primary food shoppers in South Carolina were interviewed by phone to assess their perceptions of the food environment and presence of different food outlet types in their neighborhood. The survey was repeated approximately one month after the initial administration. The intra-class correlation (ICC) and Phi coefficient are reported as measures of reliability. The majority of questions on perceptions of the neighborhood food environment appear highly reliable (ICCs range from 0.55 to 0.71), including the 3-item scale on healthy food availability (ICC 0.71). Compared to participants in rural areas, those in urban areas demonstrated better reliability for questions on opportunities to purchase fast food and perceived presence of a supercenter. More research is needed to evaluate potential rural-urban differences in reliability.

    The Childhood Trauma Questionnaire-Short Form (CTQ-SF) is the most widely used measure of childhood traumatic experiences for the retrospective assessment of adolescents and adults. It facilitates the detection of co-occurrence of traumas during childhood, in effect overcoming the lack of standardized tools for adult assessment. The current study aimed to validate the Italian Childhood Trauma Questionnaire on college students. On this scope, we compared several factor structures proposed in the literature by the original authors (Bernstein et al., 2003), as well as in cross-cultural applications. In addition, we investigated psychometric properties of the Italian CTQ-SF in terms of internal consistency reliability and convergent validity with posttraumatic stress disorder and general psychopathology. A total of 446 undergraduate students (M = 23 years, SD = 2.87) participated in the study. The confirmatory factor analyses indicated that the 5-factor solution represents the model that best fits Italian data of nonclinical samples. The unidimensionality of the scale was also not supported by present findings. Additionally, internal consistency reliability was good across the 5 scales and in line with the original version, as well as with previous applications. Correlation of the CTQ-SF with posttraumatic stress disorder and general psychopathology suggested that current posttraumatic and general symptoms were moderately significantly associated with the emotional forms of childhood trauma. Findings highlighted reliability, structure, and concurrent validity for the Italian CTQ-SF and thus supported the implementation of the Italian version of the Childhood Trauma Questionnaire-Short Form in the assessment of traumatic experiences and the screening in nonclinical groups.

    Cats more than 2 months of age have alloantibodies against the blood type antigen that they do not possess. Maternal antibodies, including alloantibodies against blood groups, are transferred to the kittens' systemic circulation when they suckle colostrum during the first 12-16 h after birth. If kittens with blood group A or AB nurse from a mother with blood group B they may develop neonatal isoerythrolysis (NI). Breeders can prevent kittens at risk of NI from nursing during the first 16-24 h; after this period it is safe to let them nurse. Kittens depend, however, on the passive transfer of antibodies from the colostrum for early protection against infections. Although it is known that kittens deprived of colostrum will also be deprived of passive systemic immunity, it is not known if this will affect their health. Therefore, the aim of this study was to evaluate kitten mortality in litters with B-mothers and A-fathers compared to litters with A-mothers. In addition, the aim was to evaluate the effects of colostrum deprivation on the health of the mothers, and the breeders' opinions and experiences of these combinations of breedings. A web-based questionnaire was constructed and distributed to breeders. The results indicate that there is no difference in mortality between planned litters that have mothers with blood group A and litters with mothers that have blood group B and fathers that have blood group A. When managing blood group incompatibility in cat all factors affecting the health of the cats, including genetic variation, should be considered.

    2017-01-30

    The development of talented athletes is a priority for many countries across the world, including China. A validated Chinese 5-factor Talent Development Environment Questionnaire (TDEQ-5) would go some way in helping researchers and practitioners investigate talent development systems within China from an evidence-based perspective. For this purpose, the 25-item English TDEQ-5 was translated to Chinese through a standardised process. The translated scale was then administered to 538 talented Chinese youth athletes. Confirmatory factor analysis revealed adequate model fit of the scale. The internal reliability, concurrent and discriminant validity, and test-retest reliability of the scale were adequately supported. The scale was also invariant across gender. It is recommended that the Chinese TDEQ-5 can be used with confidence in both applied and research settings.

    The Childhood Trauma Questionnaire (CTQ) is internationally accepted as a key tool for the assessment of childhood abuse and neglect experiences. However, there are relative few psychometric studies available and some authors have proposed two different factor solutions. We examined the dimensional structure and internal consistency of the Brazilian version of the CTQ. A total of 1,925 participants from eight different clinical and non-clinical samples including adolescents, adults and elders were considered in this study. First, we performed Confirmatory Factor Analysis to investigate the goodness of fit of the two proposed competitive factor structure models for the CTQ. We also investigated the internal consistency of all factors. Second, multi-group analyses were used to investigate measurement invariance and population heterogeneity across age groups and sex. Our findings revealed that the alternative factor structure as opposed to the original factor structure was the most appropriate model within adolescents and adults Brazilian samples. We provide further evidence for the validity and reliability of the CTQ within the Brazilian samples and report that the alternative model showed an improvement in fit indexes and may be a better alternative over the original model.

    Full Text Available Purpose: The educational environment (EE plays a very important role in effective student learning. The Dundee Ready Education Environment Measure (DREEM is a validated tool to assess the EE. This study aimed to collect baseline information about our medical student’s perception of the EE, and to identify areas of strengths and weaknesses as well as scope for improvements in the current EE. Methods: Medical students and interns were included in this cross-sectional study. The DREEM questionnaire was used to measure students’ perceptions about the EE, which has five domains: students’ perceptions of learning; students’ perceptions of teachers; students’ academic self-perceptions; students’ perceptions of atmosphere; and students’ social self-perceptions. Students were asked to respond using a 5-point Likert-type scale. Data was analyzed using suitable tests and statistical significance was set at p<0.05. Results: The mean global DREEM score was 123/200. All students had more positive than negative academic self-perception (21.24/32, perception of atmosphere (29.21/48, and perception of learning (28.99/48, while their social self-perception (17.48/28 was not too bad and perception of teachers (26.71/44 moved in the right direction. The fifth semester students perceived EE more positively than other semester students. Conclusion: The present study revealed that all students perceived their EE positively. The positive points were that teachers were knowledgeable, that students had good friends, and they were confident about passing their exams. Problem areas observed were authoritarian teachers, overemphasis on factual learning, overly teacher-centered teaching, teachers getting angry, and the need for a support system for stressed students.

    Purpose Evaluation is the main component in design and implementation of educational activities and rapid growth of educational institution programs. Outpatient medical education and clinical training environment is one of the most important parts of training of medical residents. This study aimed to determine the validity and reliability of the Persian version of Ambulatory Care Learning Educational Environment Measure (ACLEEM) questionnaire, as an instrument for assessment of educational environments in residency medical clinics. Materials and methods This study was performed on 180 residents in Shiraz University of Medical Sciences, Shiraz, Iran, in 2014–2015. The questionnaire designers’ electronic permission (by email) and the residents’ verbal consent were obtained before distributing the questionnaires. The study data were gathered using ACLEEM questionnaire developed by Arnoldo Riquelme in 2013. The data were analyzed using the SPSS statistical software, version 14, and MedCalc® software. Then, the construct validity, including convergent and discriminant validities, of the Persian version of ACLEEM questionnaire was assessed. Its internal consistency was also checked by Cronbach’s alpha coefficient. Results Five team members who were experts in medical education were consulted to test the cultural adaptation, linguistic equivalency, and content validity of the Persian version of the questionnaire. Content validity indexes were >0.9 in all items. In factor analysis of the instrument, the Kaiser–Meyer–Olkin index was 0.928 and Barlett’s sphericity test yielded the following results: X2=6,717.551, df =1,225, and P≤0.001. Besides, Cronbach’s alpha coefficient of ACLEEM questionnaire was 0.964. Cronbach’s alpha coefficients were also >0.80 in all the three domains of the questionnaire. Overall, the Persian version of ACLEEM showed excellent convergent validity and acceptable discriminant validity, except for the clinical training domain

    Full Text Available The paper reviews evidence on the construct validity and reliability of the newly developed Family Environment Questionnaire (FEQ, and presents data on the structure of socialisation practices the Slovenian parents use in daily interactions with their three-year-old children. The FEQ is a parent report measure designed to provide an assessment of individual differences in parental practices that are representative among the parents of preschool children in the given cultural community. Factor analysis of the 63 items reliably recovered a four-component solution in both, maternal and paternal self-reports indicating the following broad-band parenting practices: Authoritative Parenting, Ineffective Control, Power Assertion, and Stimulation. Variables loading high on more than one component and those that did not load on the same factor obtained from maternal and paternal data were excluded from further analyses. The 51 items that were retained and corresponded to the four factors demonstrate adequate internal consistency for both samples of respondents. In addition, parental stimulation was positively linked to authoritative parenting, while it was negatively related to ineffective control and power assertion. The mothers perceived themselves to be more authoritative and stimulative than did fathers, who described themselves as more power assertive and ineffective in control. The parent-pairs were also found to share, at least to some extent, similar parenting practices, whereas their self-perceived expression of these practices was not dependent on their child's gender.

    Full Text Available Objectives: This study aims to test the validity of the IPD-Work Consortium approach for creating comparable job strain groups between the Job Content Questionnaire (JCQ and the Demand-Control Questionnaire (DCQ. Material and Methods: A random population sample (N = 682 of all middle-aged Malmö males and females was given a questionnaire with the 14-item JCQ and 11-item DCQ for the job control and job demands. The JCQ job control and job demands scores were calculated in 3 different ways: using the 14-item JCQ standard scale formulas (method 1; dropping 3 job control items and using the 11-item JCQ standard scale formulas with additional scale weights (method 2; and the approach of the IPD Group (method 3, dropping 3 job control items, but using the simple 11-item summation-based scale formulas. The high job strain was defined as a combination of high demands and low control. Results: Between the 2 questionnaires, false negatives for the high job strain were much greater than false positives (37–49% vs. 7–13%. When the method 3 was applied, the sensitivity of the JCQ for the high job strain against the DCQ was lowest (0.51 vs. 0.60–0.63 when the methods 1 and 2 were applied, although the specificity was highest (0.93 vs. 0.87–0.89 when the methods 1 and 2 were applied. The prevalence of the high job strain with the JCQ (the method 3 was applied was considerably lower (4–7% than with the JCQ (the methods 1 and 2 were applied and the DCQ. The number of congruent cases for the high job strain between the 2 questionnaires was smallest when the method 3 was applied. Conclusions: The IPD-Work Consortium approach showed 2 major weaknesses to be used for epidemiological studies on the high job strain and health outcomes as compared to the standard JCQ methods: the greater misclassification of the high job strain and lower prevalence of the high job strain.

    Social dynamics determined by voting in a stochastic environment is analyzed for a society composed of two cohesive groups of similar size. Within the model of random walks determined by voting, explicit formulas are derived for the capital increments of the groups against the parameters of the environment and "claim thresholds" of the groups. The "unanimous acceptance" and "unanimous rejection" group rules are considered as the voting procedures. Claim thresholds are evaluated that are most beneficial to the participants of the groups and to the society as a whole.

    High-quality measurement instruments for assessing the neighbourhood environment are a prerequisite for identifying associations between the neighbourhood environment and a person's physical activity. The aim of this systematic review was to identify reliable and valid questionnaires assessing neighbourhood environmental attributes in the context of physical activity behaviours in children and adolescents. In addition, current gaps and best practice models in instrumentation and their evaluation are discussed. We conducted a systematic literature search using six databases (Web of Science, Medline, TRID, SportDISCUS, PsycARTICLES and PsycINFO). Two independent reviewers screened the identified English-language peer-reviewed journal articles. Only studies examining the measurement properties of self- or proxy-report questionnaires on any aspects of the neighbourhood environment in children and adolescents aged 3 to 18 years were included. The methodological quality of the included studies was assessed using the COSMIN checklists. We identified 13 questionnaires on attributes of the neighbourhood environment. Most of these studies were conducted in the United States (n = 7). Eight studies evaluated self-report measures, two studies evaluated parent-report measures and three studies included both administration types. While eight studies had poor methodological quality, we identified three questionnaires with substantial test-retest reliability and two questionnaires with acceptable convergent validity based on sufficient evidential basis. Based on the results of this review, we recommend that cross-culturally adapted questionnaires should be used and that existing questionnaires should be evaluated especially in diverse samples and in countries other than the United States. Further, high-quality studies on measurement properties should be promoted and measurement models (formative vs. reflexive) should be specified to ensure that appropriate methods for psychometric

    Childhood overweight and obesity are a growing concern globally, and environments, including the home and school, can contribute to this epidemic. This paper assesses the reliability of two questionnaires (parent and teacher) used in the evaluation of a community-based childhood obesity prevention intervention, the eat well be active (ewba) Community Programs. Parents and teachers were recruited from two primary schools and they completed the same questionnaire twice in 2008 and 2009. Data from both questionnaires were classified into outcomes relevant to healthy eating and activity, and target outcomes, based on the goals of the ewba Community Programs, were identified. Fourteen and 12 outcomes were developed from the parent and teacher questionnaires, respectively. Sixty parents and 28 teachers participated in the reliability study. Intraclass correlation coefficients for outcomes ranged from 0.37 to 0.92 (parent) (P questionnaire. The parent and teacher questionnaires are moderately reliable tools for simultaneously assessing child intakes, environments, attitudes, and knowledge associated with healthy eating and physical activity in the home and school and may be useful for evaluation of similar programs.

    Institute of Scientific and Technical Information of China (English)

    2002-01-01

    This paper considers the key management issue of secure group communication in a highly mobile networking environment. In such environment, there are frequent joining and leaving of members due to roaming or suspending for a period. In order to preserve forward and backward confidentiality, it is necessary to rekey every time a member joins or leaves. This paper introduces a new state-based group key management framework suitable for highly mobile environment. In this scheme, a member enters "Park" state when it is going to roam or suspend for a period, when it becomes active again, it send a request to the key server to get the current group key and changes its state to "Active" again. No rekeying is needed for a roaming, and reliable delivery of rekeying messages is not required for "Park" members. The scheme can notably reduce the communication overhead and provide an efficient method for error recovery.

    Full Text Available Designing a questionnaire is the most profound activity which makes an impact on a research in marketing. The investigation instrument finally determines the quality of this type of research. Never will a market research be able to exceed its questionnaire in point of quality. The present contribution succinctly itemizes a research project for the Romanian car market, emphasizing the importance of focus group, and appends, at the end, the concrete result, applied to the Romanian car market. The first part describes the hypotheses and sets out the objectives of the research, focusing on the market leader, i.e. Automobile Dacia Renault. The second section describes the practical process of designing the questionnaire, with a special stress laid on the impact of focus-group in the final version. The synthesis of focus group is materialized through a number of final remarks on the manner of concretely writing the questionnaire, which was put to practical use on the Romanian car market.

    Full Text Available This study evaluated the psychometric properties of an on-line version of the Zuckerman-Kuhlman-Aluja Personality Questionnaire (ZKA-PQ by sex and age. The questionnaire was responded by 1598 people, 474 males and 1124 females, with a mean age of 32.57 (SD = 11.72. Males and females differed in their responses to all personality dimensions evaluated by this instrument, in a similar way as that reported in past research. In addition, younger people scored higher in the Aggressiveness factor, especially concerning the Physical Aggression facet, whereas older people scored higher in the Activity factor. Besides, younger people scored higher in the Neuroticism and the Sensation Seeking factors, even though there were no age differences in the Extraversion factor. The ZKA-PQ five-factor structure was clear and yielded high congruence coefficients with the original Spanish validation sample. Altogether, the findings support the validity of the online version of this instrument. The ZKAPQ online version is therefore helpful in both, basic and applied research settings about human personality and individual differences.

    Childhood overweight and obesity are a growing concern globally, and environments, including the home and school, can contribute to this epidemic. This paper assesses the reliability of two questionnaires (parent and teacher) used in the evaluation of a community-based childhood obesity prevention intervention, the eat well be active (ewba) Community Programs. Parents and teachers were recruited from two primary schools and they completed the same questionnaire twice in 2008 and 2009. Data from both questionnaires were classified into outcomes relevant to healthy eating and activity, and target outcomes, based on the goals of the ewba Community Programs, were identified. Fourteen and 12 outcomes were developed from the parent and teacher questionnaires, respectively. Sixty parents and 28 teachers participated in the reliability study. Intraclass correlation coefficients for outcomes ranged from 0.37 to 0.92 (parent) (P environments, attitudes, and knowledge associated with healthy eating and physical activity in the home and school and may be useful for evaluation of similar programs.

    Background Research has highlighted variations in morbidity, mortality and health needs by ethnic group, and suggests that some ethnic groups may receive a poorer service. Aim To explore the impact of ethnic group on patients' experiences and expectations of their general practice consultation. Design of study Cross-sectional survey. Setting One general practice in a multicultural area of London. Method A total of 604 consecutive patients attending their general practice (response rate = 60.4%) who described their ethnic group as white British, black African, black African Caribbean or Vietnamese completed a measure relating to their experiences and their expectations of the general practice consultation in terms of treatment, communication, patients' agenda, patients' choice and doctor consistency. Results No differences were found for the black African or black African Caribbean patients. The Vietnamese patients reported better experiences of communication, more focus on their agenda and more attention to their choices than the white British patients. However, they also reported expecting lower levels of communication, less focus on their own agenda and reported wanting less GP consistency than the other ethnic groups. Conclusion Vietnamese patients state that they are receiving better standards of care in general practice than other ethnic groups. However, they also state that they expect less. This may illustrate a problem with assessing experiences of primary care. Higher scores of experience may not illustrate better consultations as such, but only better when compared with a lower level of initial expectation. A lower expectation is easier to fulfil.

    The goals of this study were to (1) provide preliminary reliability and validity of the Barriers to Treatment Adherence Questionnaire, developed for patients with fibromyalgia, and (2) examine barriers to adherence and general adherence to multimodal treatment during a 3-mo. period. A secondary goal was to explore in a focus discussion group format patients' perceptions of the adherence process and ways of managing the treatment program. 39 fibromyalgia patients were followed while participating in a combined outpatient program of physiotherapy, occupational therapy, nursing, and cognitive behavioral therapy. The Barriers to Treatment Adherence Questionnaire demonstrated good reliability. Construct validity of the Barriers to Treatment Adherence Questionnaire was supported through significant positive correlations with the General Adherence Scale at Months 1 and 3. In addition, a significant change was observed in scores on the Barriers to Treatment Adherence Questionnaire for the physiotherapy component of treatment, with scores decreasing between Months 2 and 3. Addressing barriers to improve adherence may maximize the benefit of treatment programs.

    We have investigated the effect of group environment on residual star formation in galaxies, using Galex NUV galaxy photometry with the SDSS group catalogue of Yang et al. (2007). We compared the (NUV $- r$) colours of grouped and non-grouped galaxies, and find a significant increase in the fraction of red sequence galaxies with blue (NUV $- r$) colours outside of groups. When comparing galaxies in mass matched samples of satellite (non-central), and non-grouped galaxies, we found a > 4{\\sigma} difference in the distribution of (NUV $- r$) colours, and an (NUV $- r$) blue fraction $> 3{\\sigma}$ higher outside groups. A comparison of satellite and non-grouped samples has found the NUV fraction is a factor of $\\sim2$ lower for satellite galaxies between $10^{10.5}M_{\\bigodot}$ and $10^{10.7}M_{\\bigodot}$, showing that higher mass galaxies are more able to form stars when not influenced by a group potential. There was a higher (NUV $- r$) blue fraction of galaxies with lower Sersic indices (n < 3) outside of ...

    We developed a food frequency questionnaire (FFQ) designed to measure the dietary practices of adult Nepalese. The present study examined the validity and reproducibility of the FFQ. To evaluate the reproducibility of the FFQ, 116 subjects completed two 115-item FFQ across a four-month interval. Six 24-h dietary recalls were collected (1 each month) to assess the validity of the FFQ. Seven major food groups and 23 subgroups were clustered from the FFQ based on macronutrient composition. Spearman correlation coefficients evaluating reproducibility for all food groups were greater than 0.5, with the exceptions of oil. The correlations varied from 0.41 (oil) to 0.81 (vegetables). All crude spearman coefficients for validity were greater than 0.5 except for dairy products, pizzas/pastas and sausage/burgers. The FFQ was found to be reliable and valid for ranking the intake of food groups for Nepalese dietary intake.

    Full Text Available Collaborative learning in an online classroom can take the form of discussion among the whole class or within smaller groups. This paper addresses the latter, examining first whether assessment makes a difference to the level of learner participation and then considering other factors involved in creating effective collaborative learning groups. Data collected over a three year period (15 cohorts from the Foundations course in the Master of Distance Education (MDE program offered jointly by University of Maryland University College (UMUC and the University of Oldenburg does not support the authors’ original hypothesis that assessment makes a significant difference to learner participation levels in small group learning projects and leads them to question how much emphasis should be placed on grading work completed in study groups to the exclusion of other strategies. Drawing on observations of two MDE courses, including the Foundations course, their extensive online teaching experience, and a review of the literature, the authors identify factors other than grading that contribute positively to the effectiveness of small collaborative learning groups in the online environment. In particular, the paper focuses on specific instructional strategies that facilitate learner participation in small group projects, which result in an enhanced sense of community, increased skill acquisition, and better learning outcomes.

    2009-01-01

    Residential styled environments for physically challenged people with neuro disabilities are rapidly replacing the standard institutional skilled nursing home. Ten trends are described that utilize residential design approaches to the physical environment while relying on home-care style methods for service delivery. Combined these two forces create powerful differentiators which make group residential settings more friendly and humane. Northern European, as well as, US best practices and prototypes are described that combine housing with services in a range of contexts. The success of northern Europeans in promulgating models of aging-in-place that keep those at risk more independent in the community or within family settings are remarkable. Topics like the impact of small group living clusters, interior design treatments, access to landscape gardens, life skill management methods, movement systems for circulation and exercise, shared space priorities, unit design trends and innovative care giving techniques are introduced. The focus of the article is on specific practices gleaned from cultures and exemplars that appear to increase autonomy, independence and privacy for those who are threatened because of their disabilities with the loss of these lifestyle attributes. Promising concepts of service organization and community outreach are combined with detailed recommendations that address the need for lift technology and safety features in bathrooms and kitchens.

    The Grupo de Estudos e Pesquisas de Tecnologia da Informação nos Processos de Trabalho em Enfermagem (Study and Research Group for Information Technology in the Nursing Working Processes, GEPETE) has the purpose of producing and socializing knowledge in information technology and health and nursing communication, making associations with research groups in this field and promoting student participation. This study was performed by the group tutors with the objective to report on the development of the virtual learning environment (VLE) and the tutors' experience as mediators of a research group using the Moodle platform. To do this, a VLE was developed and pedagogical mediation was performed following the theme of mentoring. An initial diagnosis was made of the difficulties in using this technology in interaction and communication, which permitted the proposal of continuing to use the platform as a resource to support research activities, offer lead researchers the mechanisms to socialize projects and offer the possibility of giving advice at a distance.

    Mealtimes in families with young children are increasingly of interest to nutrition and public health researchers, yet assessment tools are limited. Meals in Our Household is a new parent-report questionnaire that measures six domains: 1) structure of family meals, 2) problematic child mealtime behaviors, 3) use of food as reward, 4) parental concern about child diet, 5) spousal stress related to child's mealtime behavior, and 6) influence of child's food preferences on what other family members eat. Reliability and initial face, construct, and discriminant validity of the questionnaire were evaluated between January 2007 and December 2009 in two cross-sectional studies comprising a total of 305 parents of 3- to 11-year-old children (including 53 children with autism spectrum disorders). Internal consistencies (Cronbach's α) for the six domains averaged .77 across both studies. Test-retest reliability, assessed among a subsample of 44 parents who repeated the questionnaire after between 10 and 30 days, was excellent (Spearman correlations for the domain scores between two administrations ranged from 0.80 to 0.95). Initial construct validity of the instrument was supported by observation of hypothesized inter-relationships between domain scores that were of the same direction and similar magnitude in both studies. Consistent with discriminant validity, children with autism spectrum disorders had statistically significantly (Pmealtime behaviors, use of food as reward, parental concern about child diet, and spousal stress, as compared to typically developing children. Meals in Our Household may be a useful tool for researchers studying family mealtime environments and children's mealtime behaviors.

    Full Text Available Abstract Background Potential links between eczema and obstructive pulmonary diseases have been postulated. Previously we have reported the prevalence of upper and lower respiratory diseases and the relation to environmental and socio-economic factors in a randomly selected adult population in southern Sweden using a postal questionnaire. In the present study we wanted to analyse the prevalence of eczema and its relation to socio-economic status, heredity factors and environmental factors in an adult population. Methods Self-reported eczema, upper and lower respiratory symptoms, asthma and Chronic Bronchitis Emphysema (CBE were examined in 12,071 adults, aged 20–59 years, living in southern Sweden by using a postal questionnaire. There were comparable numbers of males and females in all age groups. Multiple logistic regression analysis (forward conditional was applied to estimate the association between the proposed risk factors (heredity, self-reported asthma and CBE, nasal symptoms, socio-economic group, environmental factors, age, gender and smoking habits and self-reported eczema. Results The response rate was 70.1%. In all, 1240 subjects (14.6% stated that they had eczema. In all age cohorts self-reported eczema was more frequently reported by women than by men (p Conclusions In this epidemiological study we see that self-reported eczema is a common disease in an adult population especially among women. Eczema seems to be linked to environment factors, obstructive pulmonary diseases and rhinitis.

    Tertiary pediatric hospitals usually provide excellent clinical services, but such centers have a lot to do for educational perfection. This study was performed to address under-graduate educational deficits and find feasible solutions. This cross-sectional study was done in a target population of 77 sixth year undergraduate medical students (response rate = 78%) who spent their 3-month pediatric rotation in the Children's Medical Center, the Pediatrics Center of Excellence in Tehran, Iran. The Dundee ready educational environment measure (DREEM) instrument was used for assessing educational environment of this subspecialized pediatric hospital. Among 60 students who answered the questionnaires, 24 were male (40%). Participants' age ranged from 23 to 24 years. The mean total score was 95.8 (48%). Comparison of scores based on students' knowledge showed no significant difference. Problematic areas were learning, academic self-perception, and social self-perception. Having an accurate schedule to train general practitioner, using new teaching methods, and providing a non-stressful atmosphere were suggested solutions.

    Full Text Available Abstract Background There is a need for valid population level measures of physical activity in young children. The aim of this paper is to report the development, and the reliability and validity, of the Preschool-age Children's Physical Activity Questionnaire (Pre-PAQ which was designed to measure activity of preschool-age children in the home environment in population studies. Methods Pre-PAQ was completed by 103 families, and validated against accelerometry for 67 children (mean age 3.8 years, SD 0.74; males 53%. Pre-PAQ categorizes activity into five progressive levels (stationary no movement, stationary with limb or trunk movement, slow, medium, or fast-paced activity. Pre-PAQ Levels 1-2 (stationary activities were combined for analyses. Accelerometer data were categorized for stationary, sedentary (SED, non-sedentary (non-SED, light (LPA, moderate (MPA and vigorous (VPA physical activity using manufacturer's advice (stationary or the cut-points described by Sirard et al and Reilly et al. Bland-Altman methods were used to assess agreement between the questionnaire and the accelerometer measures for corresponding activity levels. Reliability of the Pre-PAQ over one week was determined using intraclass correlations (ICC or kappa (κ values and percentage of agreement of responses between the two questionnaire administrations. Results Pre-PAQ had good agreement with LPA (mean difference 1.9 mins.day-1 and VPA (mean difference -4.8 mins.day-1, was adequate for stationary activity (mean difference 7.6 mins.day-1 and poor for sedentary activity, whether defined using the cut-points of Sirard et al (mean difference -235.4 mins.day-1 or Reilly et al (mean difference -208.6 mins.day-1 cut-points.

    To explore clinical protocols for the prevention of early-onset group B Streptococcus (EOGBS) disease of the newborn in Japan, we conducted a multicenter questionnaire survey. Of 32 regional centers participating in the Kyoto Neonatal Study Group, 28 provided usable data concerning prevention practices undertaken between 2000 and 2004. Twenty-three (82%) of the 28 hospitals implemented bacteriological screening to identify maternal GBS carriage, and all 23 hospitals administered intrapartum antibiotics to all screening-positive pregnant women. There were no institutes that used risk-based strategies. In the 23 hospitals, bacteriological screening was conducted mostly by lower vaginal swab alone (n = 18). Eighteen hospitals performed screening once during pregnancy, either before 34 weeks' gestation (n = 6) or between 35 and 37 weeks' gestation (n = 12). Oral antepartum antibiotics, when carriage was identified, were administered at 12 (52%) hospitals. Twenty institutes used penicillins for intrapartum prophylaxis. However, the loading dose for chemoprophylaxis ranged from 0.5 to 2 g, and the interval between repeat administrations ranged from 4 to 12 h. Although the results indicated that more than 80% of the hospitals surveyed had introduced some screening-based prevention practices, the timing of the bacteriological screening during the pregnancy, the number of screenings, and the screening sites, as well as the antibiotics used, and their dosage, varied widely. Because of these highly variable methods, the efficacy of the implementation of preventive practices could not be determined. This study is the first to have described preventive practices for EOGBS disease in Japan in the era of Centers for Disease Control and Prevention guidelines. In light of the above results, a larger study under a unifying protocol would be warranted.

    2014-07-01

    One major challenge facing the health care systems worldwide is the growing demand for registered nurses able to provide qualified nursing care for a vulnerable population. Positive learning experiences during clinical practice influence not only learning outcomes, but also how students reason in relation to future career choices. To investigate student nurses' experiences of the clinical learning environment during clinical practice in nursing homes, and to compare perceptions among student nurses with or without prior work experience as health care assistants in elderly care. A cross-sectional study was designed, utilising the Swedish version of the CLES+T evaluation scale. 260 student nurses (response rate 76%) who had completed a five week long clinical placement in nursing homes returned the questionnaire during the data collection period in 2011-2012. Data were analysed using descriptive statistics. Mann-Whitney U-test was used to examine differences in relation to students with or without prior experience of elderly care. Overall, the clinical learning environment was evaluated in a predominantly positive way. The sub-dimension Supervisory relationship displayed the highest mean value, and the lowest score was calculated for the sub-dimension Leadership style of the ward manager. Statistical significant differences between sub-groups were displayed for four out of 34 items. The supervisory relationship had the greatest impact on how student nurses experienced the clinical learning environment in nursing homes. It is therefore, of utmost importance that collaborative activities, between educational and nursing home settings, supporting the work of preceptors are established and maintained.

    Full Text Available The benefits of walking in natural environments for well-being are increasingly understood. However, less well known are the impacts different types of natural environments have on psychological and emotional well-being. This cross-sectional study investigated whether group walks in specific types of natural environments were associated with greater psychological and emotional well-being compared to group walks in urban environments. Individuals who frequently attended a walking group once a week or more (n = 708 were surveyed on mental well-being (Warwick Edinburgh Mental Well-being Scale, depression (Major Depressive Inventory, perceived stress (Perceived Stress Scale and emotional well-being (Positive and Negative Affect Schedule. Compared to group walks in urban environments, group walks in farmland were significantly associated with less perceived stress and negative affect, and greater mental well-being. Group walks in green corridors were significantly associated with less perceived stress and negative affect. There were no significant differences between the effect of any environment types on depression or positive affect. Outdoor walking group programs could be endorsed through “green prescriptions” to improve psychological and emotional well-being, as well as physical activity.

    The principal aim of the present study was to evaluate questionnaire-based information on past physical work loads (6-year recall). Effects of memory difficulties on reproducibility were evaluated for 82 subjects by comparing previously reported results on current work loads (test-retest procedure) with the same items recalled 6 years later. Validity was assessed by comparing self-reports in 1995, regarding work loads in 1989, with worksite measurements performed in 1989. Six-year reproducibility, calculated as weighted kappa coefficients (k(w)), varied between 0.36 and 0.86, with the highest values for proportion of the workday spent sitting and for perceived general exertion and the lowest values for trunk and neck flexion. The six-year reproducibility results were similar to previously reported test-retest results for these items; this finding indicates that memory difficulties was a minor problem. The validity of the questionnaire responses, expressed as rank correlations (r(s)) between the questionnaire responses and workplace measurements, varied between -0.16 and 0.78. The highest values were obtained for the items sitting and repetitive work, and the lowest and "unacceptable" values were for head rotation and neck flexion. Misclassification of exposure did not appear to be differential with regard to musculoskeletal symptom status, as judged by the calculated risk estimates. The validity of some of these self-administered questionnaire items appears sufficient for a crude assessment of physical work loads in the past in epidemiologic studies of the general population with predominantly low levels of exposure.

    Full Text Available OBJECTIVE: This study analyzes the reliability of the PHEEM questionnaire translated into Portuguese. We present the results of PHEEM following distribution to doctors in three different medical residency programs at a university hospital in Brazil. INTRODUCTION: Efforts to understand environmental factors that foster effective learning resulted in the development of a questionnaire to measure medical residents' perceptions of the level of autonomy, teaching quality and social support in their programs. METHODS: The questionnaire was translated using the modified Brislin back-translation technique. Cronbach's alpha test was used to ensure good reliability and ANOVA was used to compare PHEEM results among residents from the Surgery, Anesthesiology and Internal Medicine departments. The Kappa coefficient was used as a measure of agreement, and factor analysis was employed to evaluate the construct strength of the three domains suggested by the original PHEEM questionnaire. RESULTS: The PHEEM survey was completed by 306 medical residents and the resulting Cronbach's alpha was 0.899. The weighted Kappa was showed excellent reliability. Autonomy was rated most highly by Internal Medicine residents (63.7% ± 13.6%. Teaching was rated highest in Anesthesiology (66.7% ± 15.4%. Residents across the three areas had similar perceptions of social support (59.0% ± 13.3% for Surgery; 60.5% ± 13.6% for Internal Medicine; 61.4% ± 14.4% for Anesthesiology. Factor analysis suggested that nine factors explained 58.9% of the variance. CONCLUSIONS: This study indicates that PHEEM is a reliable instrument for measuring the quality of medical residency programs at a Brazilian teaching hospital. The results suggest that quality of teaching was the best indicator of overall response to the questionnaire.

    The SP790 study (ClinicalTrials.gov, NCT00136045) showed benefits of rotigotine over placebo in improving symptom severity of restless legs syndrome (RLS), also known as Willis-Ekbom disease, on the International Restless Legs Syndrome Study Group rating scale (IRLS), Clinical Global Impression item 1 (CGI-1), RLS 6-item questionnaire (RLS-6), and the RLS-quality of life questionnaire (RLS-QoL) in patients with moderate to severe idiopathic RLS. To provide clinical context for the IRLS and to guide the choice of assessment scales for RLS studies, our post hoc analysis of SP790 data evaluated associations between the IRLS and the CGI-1, IRLS and RLS-6, and the IRLS and RLS-QoL. Scale associations were analyzed at baseline and at the end of maintenance (EoM) using data from the safety set (rotigotine and placebo groups combined [n=458]). Changes from baseline to EoM in IRLS score vs comparator scale scores also were analyzed. There was a trend towards increasing IRLS severity category with increasing CGI-1, RLS-6, and RLS-QoL score. Pearson product moment correlation coefficients showed correlations between IRLS and comparator scale scores at baseline and EoM as well as correlations for change from baseline to EoM. Correlations between the IRLS and comparator scales were substantial. These data indicate that the IRLS is clinically meaningful. The IRLS and CGI-1 are generally sufficient to evaluate the overall severity and impact of RLS symptoms in clinical trials. Copyright © 2013 Elsevier B.V. All rights reserved.

    The wind environment around residential building groups is increasingly concerned, while the dwelling groups as the elementary unit of planning design, its quality of surrounding wind environment will directly affect people’ s life. This study based on the climatic conditions of severe cold regions, selects four dwellings groups with different openings scale and position as the research objects, and then simulates and analyzes the wind speed distribution characteristics of each pattern. Meanwhile, it extracts the wind speed values of one hundred points of each pattern and applies the coefficient of uniformity method to the ecological evaluation. It has been found that grouping pattern of buildings has a dramatic effect on the resulting airflow behavior. Configurations that contain a T⁃shaped central space with small opened side can effectively prevent and contain airflow in the site offer. The interactive influence between layout of dwelling groups and wind environment are explored, so as to provide basis for the planning design of dwelling groups.

    Full Text Available Introduction: Obsessive-compulsive disorder is considered as a rare disorder at childhood period, However studies have indicated a high prevalence of this disorder in this group. Cognitive theories of this disorder attribute a central role to dysfunctional beliefs. Given prevalence of this disorder among children and adolescents as well as further investigation in this field, the present study intends to investigate the psychometric properties of a Persian version of this scale. Methods: The OBQ-CV Persian version was completed by 547 high school students aged 15-18 years from the Shiraz city. Subjects were selected by multistage cluster sampling and data were analyzed with confirmatory factor analysis by using Lisrel software. Results: The results revealed satisfactory Composite Reliability Index (ranging from 0/72 to0/87. Moreover, in the present study four-factor structure found in original scale was confirmed by a confirmatory factor analysis representing responsibility, perfectionism/ certainty, importance/ control of thoughts, threat estimation. Conclusion: The study results supported the reliability and validity of the Persian OBQ-CV in Iranian adolescents and satisfactory Psychometric properties obtained to examine obsessive belief in none-clinical samples of adolescents. However, future research is needed to confirm these findings in a clinical sample.

    Understanding the mechanisms that lead dense environments to host galaxies with redder colors, more spheroidal morphologies, and lower star formation rates than field populations remains an important problem. As most candidate processes ultimately depend on host halo mass, accurate characterizations of the local environment, ideally tied to halo mass estimates and spanning a range in halo mass and redshift are needed. In this work, we present and test a rigorous, probabalistic method for assigning galaxies to groups based on precise photometric redshifts and X-ray selected groups drawn from the COSMOS field. The groups have masses in the range 10^13 < M_200c/M_sun < 10^14 and span redshifts 0group member galaxy sample has a purity of 84% and completeness of 92% within 0.5 R200c.

    The seven categories of the Stanford Faculty Development Program (SFDP) represent a framework for planning and assessing medical teaching. Nevertheless, so far there is no specific evaluation tool for large-group lectures that is based on these categories. This paper reports the development and psychometric validation of a short German evaluation tool for large-group lectures in medical education (SETMED-L: 'Student Evaluation of Teaching in MEDical Lectures') based on the SFDP-categories. Data were collected at two German medical schools. In Study 1, a full information factor analysis of the new 14-item questionnaire was performed. In Study 2, following cognitive debriefings and adjustments, a confirmatory factor analysis was performed. The model was tested for invariance across medical schools and student gender. Convergent validity was assessed by comparison with results of the FEVOR questionnaire. Study 1 (n = 922) yielded a three-factor solution with one major (10 items) and two minor factors (2 items each). In Study 2 (n = 2740), this factor structure was confirmed. Scale reliability ranged between α = 0.71 and α = 0.88. Measurement invariance was given across student gender but not across medical schools. Convergent validity in the subsample tested (n = 246) yielded acceptable results. The SETMED-L showed satisfactory to very good psychometric characteristics. The main advantages are its short yet comprehensive form, the integration of SFDP-categories and its focus on medical education.

    Full Text Available Introduction: Facilitating access to specialized centers and properly screen patients seeking cochlear implants are critical steps for proper rehabilitation. Objective: To describe the group of patients pre-and peri-lingual is not called for in a service evaluation of cochlear implants. Method: A retrospective study analyzed 401 questionnaires of patients pre-and peri-lingual Web site registered in the Central Brazilian cochlear implant. For the failure to call these patients were used as criteria applied some variables: age, use of hearing aids, speech therapy, duration of deafness, type of progression of hearing loss and type of communication used by the patient. Results: The group of patients with pre-and peri-lingual deafness accounted for 34% of total questionnaires completed during the period. The distribution by age found that 54% of patients were over 17 years, 30% between 9 and 17 years, and remaining less than 9 years. The duration of deafness was higher than 20 years in 50% of patients, between 10 and 20 years by 32% between 5 and 10 years in 9% and between 0 and 5 years in 9%. Regarding the performance of voice rehabilitation 58% of patients had performed and 42% did not. Regarding the mode of communication 49% had global communication, 18% LIBRAS, 6% oral communication, 26% no communication. Conclusion: Advanced age, duration of deafness high, so mostly no oral communication and lack of voice rehabilitation were crucial to the failure to call these patients.

    2009-04-01

    A work group was convened to identify the core challenges, content gaps, and corresponding possible solutions for improving food- and physical activity-environment instrumentation. Identified challenges included instrument proliferation, the scaling or grain of instruments and appropriate aggregation to the neighborhood or community level, and unknown sensitivity to change of most instruments. Solutions for addressing these challenges included establishing an interactive and real-time instrument repository, developing and enforcing high standards for instrument reporting, increasing community-researcher collaborations, and implementing surveillance of food and physical activity environment. Solid instrumentation will accelerate a better understanding of food- and physical activity-environment effects on eating and physical activity behaviors.

    We examine the dependence of the fraction of galaxies containing pseudo bulges on environment for a flux limited sample of ˜5000 SDSS galaxies. We have separated bulges into classical and pseudo bulge categories based on their position on the Kormendy diagram. Pseudo bulges are thought to be formed by internal processes and are a result of secular evolution in galaxies. We attempt to understand the dependence of secular evolution on environment and morphology. Dividing our sample of disc+bulge galaxies based on group membership into three categories: central and satellite galaxies in groups and isolated field galaxies, we find that pseudo bulge fraction is almost equal for satellite and field galaxies. Fraction of pseudo bulge hosts in central galaxies is almost half of the fraction of pseudo bulges in satellite and field galaxies. This trend is also valid when only galaxies are considered only spirals or S0. Using the projected fifth nearest neighbour density as measure of local environment, we look for the dependence of pseudo bulge fraction on environmental density. Satellite and field galaxies show very weak or no dependence of pseudo bulge fraction on environment. However, fraction of pseudo bulges hosted by central galaxies decreases with increase in local environmental density. We do not find any dependence of pseudo bulge luminosity on environment. Our results suggest that the processes that differentiate the bulge types are a function of environment while processes responsible for the formation of pseudo bulges seem to be independent of environment.

    2009-06-01

    Full Text Available Abstract Background Older studies have shown that patients often do not understand the terms used by doctors and many do not even have a rudimentary understanding of anatomy. The present study was designed to investigate the levels of anatomical knowledge of different patient groups and the general public in order to see whether this has improved over time and whether patients with a specific organ pathology (e.g. liver disease have a relatively better understanding of the location of that organ. Methods Level of anatomical knowledge was assessed on a multiple-choice questionnaire, in a sample of 722 participants, comprising approximately 100 patients in each of 6 different diagnostic groups and 133 in the general population, using a between-groups, cross-sectional design. Comparisons of relative accuracy of anatomical knowledge between the present and earlier results, and across the clinical and general public groups were evaluated using Chi square tests. Associations with age and education were assessed with the Pearson correlation test and one-way analysis of variance, respectively. Results Across groups knowledge of the location of body organs was poor and has not significantly improved since an earlier equivalent study over 30 years ago (χ2 = 0.04, df = 1, ns. Diagnostic groups did not differ in their overall scores but those with liver disease and diabetes were more accurate regarding the location of their respective affected organs (χ2 = 18.10, p 2 = 10.75, p Conclusion Many patients and general public do not know the location of key body organs, even those in which their medical problem is located, which could have important consequences for doctor-patient communication. These results indicate that healthcare professionals still need to take care in providing organ specific information to patients and should not assume that patients have this information, even for those organs in which their medical problem is located.

  18. Near-ultraviolet signatures of environment-driven galaxy quenching in Sloan Digital Sky Survey groups

    2017-01-01

    We have investigated the effect of group environment on residual star formation in galaxies, using Galaxy Evolution Explorer near-ultraviolet (NUV) galaxy photometry with the Sloan Digital Sky Survey group catalogue of Yang et al. We compared the (NUV - r) colours of grouped and non-grouped galaxies, and find a significant increase in the fraction of red sequence galaxies with blue (NUV - r) colours outside of groups. When comparing galaxies in mass-matched samples of satellite (non-central), and non-grouped galaxies, we found a >4σ difference in the distribution of (NUV - r) colours, and an (NUV - r) blue fraction >3σ higher outside groups. A comparison of satellite and non-grouped samples has found the NUV fraction is a factor of ˜2 lower for satellite galaxies between 1010.5 and 10^{10.7} M_{⊙}, showing that higher mass galaxies are more likely to have residual star formation when not influenced by a group potential. There was a higher (NUV - r) blue fraction of galaxies with lower Sérsic indices (n < 3) outside of groups, not seen in the satellite sample. We have used stellar population models of Bruzual & Charlot with multiple burst, or exponentially declining star formation histories to find that many of the (NUV - r) blue non-grouped galaxies can be explained by a slow (˜2 Gyr) decay of star formation, compared to the satellite galaxies. We suggest that taken together, the difference in (NUV - r) colours between samples can be explained by a population of secularly evolving, non-grouped galaxies, where star formation declines slowly. This slow channel is less prevalent in group environments where more rapid quenching can occur.

    2006-07-01

    Full Text Available Abstract Background Environmental factors are increasingly being implicated as key influences on children's physical activity. Few studies have comprehensively examined children's perceptions of their environment, and there is a paucity of literature on acceptable and reliable scales for measuring these. This study aimed to develop and test the acceptability and reliability of a scale which examined a broad range of environmental perceptions among children. Methods Based on constructs from ecological models, a survey incorporating items on children's perceptions of the physical and social environment at home and in the neighbourhood was developed. This was administered on two occasions, nine days apart, to a sample of 39 children aged 11 years (54% boys, attending a metropolitan Australian elementary school. The acceptability of the survey was determined by the proportion of missing responses to each item. The test-retest reliability of individual items, scores and scales were determined using Kappa statistics and percent agreement for categorical variables, and intraclass correlation coefficients (ICC for continuous variables. Results There were few missing responses to each question, with only 4% of all responses missing. Although some Kappa values were low, all categorical variables showed acceptable reliability when examined for percent agreement between test and retest (range 68%–100% agreement. Continuous variables all showed moderate to good ICC values (range 0.72–0.92. Conclusion Findings suggest this questionnaire is reliable and acceptable to children for assessing environmental perceptions relevant to physical activity among 11-year-old children.

  3. Pseudomonas putida and Pseudomonas fluorescens Species Group Recovery from Human Homes Varies Seasonally and by Environment.

    Directory of Open Access Journals (Sweden)

    Susanna K Remold

    Full Text Available By shedding light on variation in time as well as in space, long-term biogeographic studies can help us define organisms' distribution patterns and understand their underlying drivers. Here we examine distributions of Pseudomonas in and around 15 human homes, focusing on the P. putida and P. fluorescens species groups. We describe recovery from 10,941 samples collected during up to 8 visits per home, occurring on average 2.6 times per year. We collected a mean of 141 samples per visit, from sites in most rooms of the house, from the surrounding yards, and from human and pet occupants. We recovered Pseudomonas in 9.7% of samples, with the majority of isolates being from the P. putida and P. fluorescens species groups (approximately 62% and 23% of Pseudomonas samples recovered respectively. Although representatives of both groups were recovered from every season, every house, and every type of environment sampled, recovery was highly variable across houses and samplings. Whereas recovery of P. putida group was higher in summer and fall than in winter and spring, P. fluorescens group isolates were most often recovered in spring. P. putida group recovery from soils was substantially higher than its recovery from all other environment types, while higher P. fluorescens group recovery from soils than from other sites was much less pronounced. Both species groups were recovered from skin and upper respiratory tract samples from healthy humans and pets, although this occurred infrequently. This study indicates that even species that are able to survive under a broad range of conditions can be rare and variable in their distributions in space and in time. For such groups, determining patterns and causes of stochastic and seasonal variability may be more important for understanding the processes driving their biogeography than the identity of the types of environments in which they can be found.

    Full Text Available Communication technologies have a renovating role in contemporaneity with regard to human interaction. One can however highlight their influence on other everyday aspects, like their influence in research. The objective of this paper is to describe and discuss the aspects that involve the application of focal groups in a virtual environment, denominated on-line focal groups, with the aim of highlighting factors that can guide their use in research, especially for research which is geared towards investigating opinions and perceptions of social players. The aspects broached in this paper are based in part on the application experience of the players, with a view to elaborating a doctorate thesis. The theoretical fundamentals of presential focal groups and their migration to the virtual environment are also broached. Finally some suggestions are presented to those who are interested in this research strategy, based on the results obtained through this experience.

    Background Body image has implications for psychosocial functioning and quality of life and its disturbance is reported in a broad range of psychiatric disorders. In view of the lack of instruments in Dutch measuring body image as a broad concept, we set out to make an instrument available that reflects the multidimensional character of this construct by including more dimensions than physical appearance. The Dresden Körperbildfragebogen (DBIQ, Dresden Body Image Questionnaire) particularly served this purpose. The DBIQ consists of 35 items and five subscales: body acceptance, sexual fulfillment, physical contact, vitality, and self-aggrandizement. The main objective of the present study was to evaluate the psychometric properties of the Dutch translation of the Dresden Body Image Questionnaire (DBIQ-NL) in a non-clinical sample. Methods The psychometric properties of the DBIQ-NL were examined in a non-clinical sample of 988 respondents aged between 18 and 65. We investigated the subscales' internal consistency and test-retest reliability. In order to establish construct validity we evaluated the association with a related construct, body cathexis, and with indices of self-esteem and psychological wellbeing. The factor structure of the DBIQ-NL was examined via confirmatory factor analysis (CFA). The equivalence of the measurement model across sex and age was evaluated by multiplegroup confirmatory factor analyses. Results Confirmatory factor analyses showed a structure in accordance with the original scale, where model fit was improved significantly by moving one item to another subscale. Multiple group confirmatory factor analysis across sex and age demonstrated partial strong invariance. Internal consistency was good with little overlap between the subscales. Temporal reliability and construct validity were satisfactory. Conclusion Results indicate that the DBIQ-NL is a reliable and valid instrument for non-clinical subjects. This provides a sound basis for

Methods Based on the alerting military group psychological stress of parachute jump of parachute soldiers. After the questionnaire was confirmed initially, we made a test through the three independent samples among the different military group in different environments. After the testing of reliability and validity and the item analysis,the methods of estimation were modified and added some items and dimensions and in order to make the questionnaire more perfectly. Results Forty-four items were selected in the draft. Twenty-eight were included in the initial questionnaire. Reliability: this questionnaire has been found to have moderately acceptable internal consistency (Cronbach alpha=0.93;Spearman-Brown split half reliability= 0.90; Two weeks test-retest reliability= 0.82). Construct-related validity: the results of factor analysis for the two independent samples were quite similar.Thirty-two items were divided into six common factors. Total variance explained by the six factors was 60.30% and 59.94%, respectively, and all the factor loadings were above 0.4.Concurrent validity: this scale total score were negatively correlated with SCL-90 (-0.55), SAS (-0.43) and SDS (-0.58). Predictive validity: the predictive validity of this tool has been established. Parachute soldiers who got higher total score in this questionnaire had been gotten better military training performance than those who got lower total score in this questionnaire. Conclusion The reliability, structure validity, concurrent validity and alerting discrimination of the developed questionnaire were satisfying. The questionnaire could be used in alerting the psychological stress of military group.%目的 修订编制军事群体

    The Harvard Trauma Questionnaire (HTQ) remains the most widely used screening measure for post-traumatic stress disorder (PTSD) in the refugee and post-conflict field. The present study is the first to test the factorial structure and measurement invariance of the HTQ according to DSM-5 criteria across gender and ethnic groups in the ethnically diverse society of post-conflict Sri Lanka. The survey sample included 5136 participants (86% response rate) followed up 12 months after a baseline nationally representative survey undertaken in Sri Lanka in 2014. Exposure to conflict-related traumatic experiences (TEs) generating a trauma count (TC), and symptoms of PTSD were assessed using a modified version of the HTQ adapted to the local context. The final analytic sample included 4260 participants after excluding records with missing data on key variables. We conducted Multigroup Confirmatory Factor Analysis (MG-CFA) to test the four-factor (DSM-5 consistent) and three-factor (DSM-IV-TR) models of PTSD, then assessing measurement invariance of the four factor model by gender and ethnic groups. The three-factor and four-factor DSM-5 model each produced a good fit across the sample as a whole. In addition, there was configural, metric, and scalar invariance for the four-factor model both by gender and ethnicity. The trauma count was directly associated with each of the symptom domains of the four factor model. Our findings provide support for the capacity of the modified HTQ to measure the DSM5 construct of PTSD across gender and key ethnic groupings in Sri Lanka. Confirmation of our findings in other cultures will be important. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available The purpose of this paper is to analyze the interpersonal relationships within a sports group formedin the lock-up environment in order to reeducate the convicts by observing the sports norms and rules. Using asociometric method, the quiz has been used for a group of 15 convicts volunteered for educational andrecreational sporting activities (e.g. football developed within the “Popa Spaca” Maximum Security Prison fromTimisoara. By means of the sociomatrix and sociogram, it has been calculated the sociometric indexes,measuring various types of existing relationships as well as the positions held by the subjects. One feature of thisgroup is that of being an informal group, or is determining the election of an informal leader on the ground ofsporting abilities and knowledge, the group operating as a formal leader, elected by the larger group of convicts.But on the sports field, the formal leader of the group accepts another leader and participates together with himat the activities and football games. The primary group has a cohesion which allows it to function but also tocreate a sporting identity, determining its classification in the affiliation group for the most of the participatingsubjects but also the possibility for it to be a reference group for the non participating convicts at the sportingactivities.

    The Overexcitability Questionnaire-Two (OEQ-II) measures the degree and nature of overexcitability, which assists in determining the developmental potential of an individual according to Dabrowski's Theory of Positive Disintegration. Previous validation studies using frequentist confirmatory factor analysis, which postulates exact parameter constraints, led to model rejection and a long series of model modifications. Bayesian structural equation modeling (BSEM) allows the application of zero-mean, small-variance priors for cross-loadings, residual covariances, and differences in measurement parameters across groups, better reflecting substantive theory and leading to better model fit and less overestimation of factor correlations. Our BSEM analysis with a sample of 516 students in higher education yields positive results regarding the factorial validity of the OEQ-II. Likewise, applying BSEM-based alignment with approximate measurement invariance, the absence of non-invariant factor loadings and intercepts across gender is supportive of the psychometric quality of the OEQ-II. Compared to males, females scored significantly higher on emotional and sensual overexcitability, and significantly lower on psychomotor overexcitability.

    Full Text Available Introduction: Overweight and primary obesity in children and adolescents is a crucial problem in public health. Obese children and adolescents are especially susceptible to obesity in adulthood and consequently exposed to many obesity related diseases. Objective: Evaluation of overweight and primary obesity in urban and rural youth populations and comparison of life style concerning: physical activity, sedentary behaviors, dietary habits among overweight and obese adolescents and their peers with proper Body Mass Index value. Materials and methods: The study was performed in the group of 136 students from junior high school. The students with BMI value over 85th percentile of sex-specific growth charts were classified as overweight. Research tool was a questionnaire. Results: 15,9% of adolescents were overweight, out of which 4,5% were obese. There was not a significant relation between Body Mass Index and the place of residence. Overweight and obese adolescents revealed lower physical activity and tendency to spend much more time playing computer games. Adolescents with overweight or obesity did not regularly have breakfast at weekends, more often had sweets and sweet drinks and also high energy and very salty snacks instead. Conclusions: Overweight and obesity is a serious problem among students from junior high school population which calls for taking immediate preventive measures to promote healthy lifestyle among children and adolescents.

    This paper presents the SLMeetingRoom, a virtual reality online environment to support group meetings of geographically dispersed participants. A prototype was developed to demonstrate the feasibility of the approach using the Second Life platform. Ten additional components had to be added to Second Life environment to support group work essential activities such as participants' communication, tasks' and participants' coordination, participants' collaboration and work evolution's perception. Empirical studies, both pilot and experiment, were developed comparing four different meeting settings: face-to-face, videoconference, stand Second Life and SLMeetingRoom. The study involved graduate students enrolled in the Interface and Multimedia discipline at the Fluminense Federal University (UFF) in Brazil. Results indicated that groups working within SLMeetingRoom environment presented similar results as face-to-face meeting as far as sense of presence is concerned and with low cognitive effort. Task completion and degree of participation were not affected by the meeting set up. It was concluded that Second Life, in conjunction with the SLMeetingRoom components, is a good tool for holding synchronous remote meetings and coexists with other electronic meeting technologies.

    The polar environment is often seen as a good analog for long-term space missions in terms of isolation and confinement. This paper focuses on the psychological adaptation of both the men and women in mixed-gender groups in the French polar station Dumont d'Urville. The first 49 expeditions to this station were composed of men only in groups of 25-30. In 2000, two women were included in the first mixed-gender wintering group, followed by five women in 2001. This study on coping strategies and psychological adaptation was included in an end-of-mission debriefing performed by a psychologist. Data were collected using a few quantitative tools and a semi-structured interview, and focused on adaptation to wintering, coping strategies, and information on interpersonal relationships. Including women in a wintering group seems to have had positive effects on the general climate of the group by reducing men's rude behavior, but it also seems to be an important stressor for both men and women when the females' average age is close to the males' because seduction behaviors appear and rivalry, frustration, and sexual harassment frequently result. The use of problem-oriented strategies helps women to adapt. There are strong arguments indicating that living in an isolated and confined environment magnifies the usual difficulties that arise in mixed-gender relationships. Difficulties may be magnified in space since the group size is smaller and the confinement more extreme. This implies the need for rigorous select-in criteria for both men and women, especially for relational criteria, and for group training after selection.

    Previous research on interpersonal synchrony has mainly investigated small groups in isolated laboratory settings, which may not fully reflect the complex and dynamic interactions of real-life social situations. The present study expands on this by examining group synchrony across a large number of individuals in a naturalistic environment. Smartphone acceleration measures were recorded from participants during a music set in a dance club and assessed to identify how group movement synchrony covaried with various features of the music. In an evaluation of different preprocessing and analysis methods, giving more weight to front-back movement provided the most sensitive and reliable measure of group synchrony. During the club music set, group synchrony of torso movement was most strongly associated with pulsations that approximate walking rhythm (100–150 beats per minute). Songs with higher real-world play counts were also correlated with greater group synchrony. Group synchrony thus appears to be constrained by familiarity of the movement (walking action and rhythm) and of the music (song popularity). These findings from a real-world, large-scale social and musical setting can guide the development of methods for capturing and examining collective experiences in the laboratory and for effectively linking them to synchrony across people in daily life.

    Compact groups, with their high number densities, small velocity dispersions, and an interstellar medium that has not been fully processed, provide a local analog to conditions of galaxy interactions in the earlier universe. The frequent and prolonged gravitational encounters that occur in compact groups affect the evolution of the constituent galaxies in a myriad of ways, for example, gas processing and star formation. Recently, a statistically significant "gap" has been discovered in the mid-infrared (MIR: 3.6-8 µm) IRAC color space of compact group galaxies. This gap is not seen in field samples and is a new example of how the compact group environment may affect the evolution of member galaxies. In order to investigate the origin and nature of this gap, we have compiled a larger sample of 37 compact groups in addition to the original 12 groups studied by Johnson et al. (yielding 174 individual galaxies with reliable MIR photometry). We find that a statistically significant deficit of galaxies in this gap region of IRAC color space is persistent in the full sample, lending support to the hypothesis that the compact group environment inhibits moderate specific star formation rates. Using this expanded sample, we have more fully characterized the distribution of galaxies in this color space and quantified the low-density region more fully with respect to MIR bluer and MIR redder colors. We note a curvature in the color-space distribution, which is fully consistent with increasing dust temperature as the activity in a galaxy increases. This full sample of 49 compact groups allows us to subdivide the data according to physical properties of the groups. An analysis of these subsamples indicates that neither projected physical diameter nor density shows a trend in color space within the values represented by this sample. We hypothesize that the apparent lack of a trend is due to the relatively small range of properties in this sample, whose groups have already been

    Full Text Available Abstract With the popularity of group-oriented applications, secure group communication has recently received much attention from cryptographic researchers. A group key exchange (GKE protocol allows that participants cooperatively establish a group key that is used to encrypt and decrypt transmitted messages. Hence, GKE protocols can be used to provide secure group communication over a public network channel. However, most of the previously proposed GKE protocols deployed in wired networks are not fully suitable for wireless network environments with low-power computing devices. Subsequently, several GKE protocols suitable for mobile or wireless networks have been proposed. In this article, we will propose a more efficient group key exchange protocol with dynamic joining and leaving. Under the decision Diffie-Hellman (DDH, the computation Diffie-Hellman (CDH, and the hash function assumptions, we demonstrate that the proposed protocol is secure against passive attack and provides forward/backward secrecy for dynamic member joining/leaving. As compared with the recently proposed GKE protocols, our protocol provides better performance in terms of computational cost, round number, and communication cost.

    The Arecibo Galaxy Environment Survey (AGES) is one of several HI surveys utilising the new Arecibo L-band Feed Array (ALFA) fitted to the 305m radio telescope at Arecibo. The survey is specifically designed to investigate various galactic environments to higher sensitivity, higher velocity resolution and higher spatial resolution than previous fully sampled, 21 cm multibeam surveys. The emphasis is on making detailed observations of nearby objects although the large system bandwidth (100 MHz) will allow us to quantify the HI properties over a large instantaneous velocity range. In this paper we describe the survey and its goals and present the results from the precursor observations of a 5 degree x 1 degree region containing the nearby (~10 Mpc) NGC 628 group. We have detected all the group galaxies in the region including the low mass (M{HI}~10^7Mo) dwarf, dw0137+1541 (Briggs, 1986). The fluxes and velocities for these galaxies compare well with previously published data. There is no intra-group neutral gas...

    Against the backdrop of increasing interest in the relationship between Nature and health, this study examined the effect of perceived environment type and indicators of perceived environmental quality on short-term emotional well-being following outdoor group walks. Participants (n = 127) of a national group walk program completed pre- and post-walk questionnaires for each walk attended (n = 1009) within a 13-week study period. Multilevel linear modelling was used to examine the main and moderation effects. To isolate the environmental from the physical activity elements, analyses controlled for walk duration and perceived intensity. Analyses revealed that perceived restorativeness and perceived walk intensity predicted greater positive affect and happiness following an outdoor group walk. Perceived restorativeness and perceived bird biodiversity predicted post-walk negative affect. Perceived restorativeness moderated the relationship between perceived naturalness and positive affect. Results suggest that restorative quality of an environment may be an important element for enhancing well-being, and that perceived restorativeness and naturalness of an environment may interact to amplify positive affect. These findings highlight the importance of further research on the contribution of environment type and quality on well-being, and the need to control for effects of physical activity in green exercise research.

    Disk galaxies in compact galaxy groups exhibit a remarkable shortfall of neutral hydrogen compared to both isolated spirals and spirals in more loose groups, but the origin of this HI deficiency remains unclear. Based on a sample of highly HI deficient compact galaxy groups, here updated to also include HCG 58 and HCG 93, we summarise the first results of a multi-wavelength campaign aimed at understanding the processes responsible for modifying the HI content of galaxy disks in these environments. While tidal stripping, ram pressure stripping by hot intragroup gas, and star-formation induced strangulation could individually be affecting the ISM in some of the group members, these processes each face specific difficulties in explaining the inferred deficiency of HI for the sample as a whole. A complete picture of the mechanisms driving the ISM evolution in the disk galaxies of these groups has thus yet to emerge, but promising avenues for further progress in this field are briefly discussed on the basis of the...

    Advanced Practice Clinicians (APCs) in collaborative practice represent a diverse and valuable group of health care professionals, including nurse practitioners, physician assistants, nurse anesthetists, and nurse midwives. Because these healthcare professionals have been identified as part of the solution to physician shortages, it is critical for health networks to examine and address issues affecting collaborative relationships. We invited our network APCs to participate in focus group sessions to determine both attributes and barriers to an ideal work environment. Four major themes emerged: (1) compensation, (2) network representation, (3) employment structure, and (4) workplace culture. While issues relating to compensation and representation were prevalent, discussions also revealed the importance of relationships and communication. To ensure successful collaboration and, thereby, reduce clinician turnover, leaders must address gaps between the existing and ideal states in structural factors affecting job satisfaction (Themes 1-3) as well as the behavioral factors represented in workplace culture (Theme 4).

    Context: Type Ia supernova observations on scales of thousands of Mpc show that the global expansion of the universe is accelerated by antigravity produced by the enigmatic dark energy contributing 3/4 of the total energy of the universe. Aims: Does antigravity act on small scales as well as large? As a continuation of our efforts to answer this crucial question we combine high accuracy observations of the galaxy flows around the Local Group and the nearby M 81 and CenA groups to observe the effect of the dark energy density on local scales of a few Mpc. Methods: We use an analytical model to describe non-uniform static space-time regions around galaxy groups. In this context it is useful to present the Hubble flow in a normalized Hubble diagram V/Hv Rv vs. r/R_v, where the vacuum Hubble constant Hv depends only on the cosmological vacuum density and the zero-gravity distance Rv depends on the vacuum density and on the mass of the galaxy group. We have prepared the normalized Hubble diagrams for the LG, M 81 and CenA group environments for different values of the assumed vacuum energy density, using a total of about 150 galaxies, for almost all of which the distances have been measured by the HST. Results: The normalized Hubble diagram, where we identify dynamically different regions, is in agreement with the standard vacuum density (Ωv = 0.77~h_70-2), the out-flow of galaxies clearly being controlled by the minimum energy condition imposed by the central mass plus the vacuum density. A high vacuum density 1.6~h_70-2 violates the minimum energy limit, while a low density 0.1~h_70-2 leaves the start of the Hubble flow around 1-2 Mpc with the slope close to the global value obscure. We also consider the subtle relation of the zero-gravity radius Rv to the zero-velocity distance R0 appearing in the usual retarded expansion around a mass M: in a vacuum-dominated flat universe R0 ≈ 0.76 R_v. Conclusions: The normalized Hubble diagram appears to be a good way to

    We analyse the observed correlation between galaxy environment and H-alpha emission line strength, using volume-limited samples and group catalogues of 24968 galaxies drawn from the 2dF Galaxy Redshift Survey (Mb<-19.5) and the Sloan Digital Sky Survey (Mr<-20.6). We characterise the environment by 1) Sigma_5, the surface number density of galaxies determined by the projected distance to the 5th nearest neighbour; and 2) rho1.1 and rho5.5, three-dimensional density estimates obtained by convolving the galaxy distribution with Gaussian kernels of dispersion 1.1 Mpc and 5.5 Mpc, respectively. We find that star-forming and quiescent galaxies form two distinct populations, as characterised by their H-alpha equivalent width, EW(Ha). The relative numbers of star-forming and quiescent galaxies varies strongly and continuously with local density. However, the distribution of EW(Ha) amongst the star-forming population is independent of environment. The fraction of star-forming galaxies shows strong sensitivity t...

    The modern primary healthcare workforce needs to be resilient. Early research framed professional resilience as avoiding 'burnout'; however, more recent literature has introduced the concept of positive adaptation to professional challenges, which results in individuals thriving in their role. To explore what primary health professionals working in challenging environments consider to be characteristics of resilience and what promotes or challenges professional resilience. A qualitative focus group in north east Scotland. Five focus groups were held with 20 health professionals (six GPs, nine nurses, four pharmacists, and a practice manager) based in rural or deprived city areas in the north east of Scotland. Inductive thematic analysis identified emerging themes. Personal resilience characteristics identified were optimism, flexibility and adaptability, initiative, tolerance, organisational skills, being a team worker, keeping within professional boundaries, assertiveness, humour, and a sense of self-worth. Workplace challenges were workload, information overload, time pressures, poor communication, challenging patients, and environmental factors (rural location). Promoters of professional resilience were strong management support, teamwork, workplace buffers, and social factors such as friends, family, and leisure activities. A model of health professional resilience is proposed that concurs with existing literature but adds the concept of personal traits being synergistic with workplace features and social networks. These facilitate adaptability and enable individual health professionals to cope with adversity that is inevitably part of the everyday experience of those working in challenging healthcare environments. © British Journal of General Practice 2016.

    Human group activity recognition is a very complex and challenging task, especially for Partially Observable Group Activities (POGA) that occur in confined spaces with limited visual observability and often under severe occultation. In this paper, we present IRIS Virtual Environment Simulation Model (VESM) for the modeling and simulation of dynamic POGA. More specifically, we address sensor-based modeling and simulation of a specific category of POGA, called In-Vehicle Group Activities (IVGA). In VESM, human-alike animated characters, called humanoids, are employed to simulate complex in-vehicle group activities within the confined space of a modeled vehicle. Each articulated humanoid is kinematically modeled with comparable physical attributes and appearances that are linkable to its human counterpart. Each humanoid exhibits harmonious full-body motion - simulating human-like gestures and postures, facial impressions, and hands motions for coordinated dexterity. VESM facilitates the creation of interactive scenarios consisting of multiple humanoids with different personalities and intentions, which are capable of performing complicated human activities within the confined space inside a typical vehicle. In this paper, we demonstrate the efficiency and effectiveness of VESM in terms of its capabilities to seamlessly generate time-synchronized, multi-source, and correlated imagery datasets of IVGA, which are useful for the training and testing of multi-source full-motion video processing and annotation. Furthermore, we demonstrate full-motion video processing of such simulated scenarios under different operational contextual constraints.

    We present the Palomar Transient Factory discoveries and the photometric and spectroscopic observations of PTF11kmb and PTF12bho. We show that both transients have properties consistent with the class of calcium-rich gap transients, specifically lower peak luminosities and rapid evolution compared to ordinary supernovae, and a nebular spectrum dominated by [Ca ii] emission. A striking feature of both transients is their host environments: PTF12bho is an intracluster transient in the Coma Cluster, while PTF11kmb is located in a loose galaxy group, at a physical offset ∼150 kpc from the most likely host galaxy. Deep Subaru imaging of PTF12bho rules out an underlying host system to a limit of {M}R> -8.0 {mag}, while Hubble Space Telescope imaging of PTF11kmb reveals a marginal counterpart that, if real, could be either a background galaxy or a globular cluster. We show that the offset distribution of Ca-rich gap transients is significantly more extreme than that seen for SNe Ia or even short-hard gamma-ray bursts (sGRBs). Thus, if the offsets are caused by a kick, they require higher kick velocities and/or longer merger times than sGRBs. We also show that almost all Ca-rich transients found to date are in group and cluster environments with elliptical host galaxies, indicating a very old progenitor population; the remote locations could partially be explained by these environments having the largest fraction of stars in the intragroup/intracluster light following galaxy–galaxy interactions.

  9. Sedimentary depositional environments of uranium and petroleum host rocks of the Jackson Group, south Texas

    Determination of depositional environments in rocks of the Jackson Group of late Eocene age aids in the exploration for uranium and petroleum in south Texas. During deposition of the Jackson Group, conditions were similar to those existing along the modern Gulf Coast of Texas except for a less arid climate and a greater supply of volcanic sediment. Sedimentary depositional environments recognized in both the modern coast and the Jackson rocks, in order from sea toward land, are: shoreface, beach, lagoon and bay, and paludal. Sediment deposited in these environments in places is interbedded with or transected by fluvial sediment. Both uranium and petroleum are found in the shoreface, beach, and fluvial facies. These facies are characterized by permeable well-sorted sandstone, which is commonly overlain and underlain by less permeable mudstone. A typical vertical sequence in ascending order through a unit containing a beach sandstone facies is (1) lagoonal or paludal clay stone and siltstone, (2) crossbedded fine-grained beach sandstone which contains Ophiomorpha burrows and, which, in places, is locally interbedded with lacustrine or lagoonal mudstone, (3) weakly laminated beach sandstone which contains root impressions at the top and Ophiomorpha, and (4) lagoonal or paludal claystone and siltstone. Gulfward, the beach sandstone apparently grades into highly burrowed, generally finer grained, more poorly sorted, less porous shoreface rocks. The beach facies may include barrier island beaches and mainland beaches, some of which were probably cheniers. Beach facies sandstone units extend many miles along the depositional strike, which nearly parallels the present outcrop strike, but extend only a mile or two (2-3 km) normal to the depositional strike into the subsurface. Recognition of the various facies in outcrops and drill holes is necessary for determination of true stratigraphic relations and for aid in exploration for beach and fluvial sandstone favorable for

    E-waste is the fastest growing waste in the solid waste stream in the urban environment. It has become a widely recognised social and environmental problem; therefore, proper management is vital to protecting the fragile environment from its improper disposal. Questionnaire surveys were conducted to determine the knowledge of environmental impacts of e-waste disposal as it relates to mobile phones among different gender and age groups in China, Laos, and Thailand. The results revealed that gender was positively correlated with their knowledge of the status of environmental conditions (P104) (r = 0.077, n = 1994, p e-waste-related laws. Thus, an effort to bridge the gaps through initiating proper educational programmes in these two countries is necessary.

    In a deforming anatomic environment, the motion of an instrument suffers from complex geometrical and dynamic constraints, robot assisted minimally invasive surgery therefore requires more sophisticated skills for surgeons. This paper proposes a novel dynamic virtual fixture (DVF) to enhance the surgical operation accuracy of admittance-type medical robotics in the deforming environment. A framework for DVF on the Euclidean Group SE(3) is presented, which unites rotation and translation in a compact form. First, we constructed the holonomic/non-holonomic constraints, and then searched for the corresponded reference to make a distinction between preferred and non-preferred directions. Second, different control strategies are employed to deal with the tasks along the distinguished directions. The desired spatial compliance matrix is synthesized from an allowable motion screw set to filter out the task unrelated components from manual input, the operator has complete control over the preferred directions; while the relative motion between the surgical instrument and the anatomy structures is actively tracked and cancelled, the deviation relative to the reference is compensated jointly by the operator and DVF controllers. The operator, haptic device, admittance-type proxy and virtual deforming environment are involved in a hardware-in-the-loop experiment, human-robot cooperation with the assistance of DVF controller is carried out on a deforming sphere to simulate beating heart surgery, performance of the proposed DVF on admittance-type proxy is evaluated, and both human factors and control parameters are analyzed. The DVF can improve the dynamic properties of human-robot cooperation in a low-frequency (0 ~ 40 rad/sec) deforming environment, and maintain synergy of orientation and translation during the operation. Statistical analysis reveals that the operator has intuitive control over the preferred directions, human and the DVF controller jointly control the

    We took advantage of the wealth of information provided by the first ~10000 galaxies of the zCOSMOS-bright survey and its group catalogue to study the complex interplay between group environment and galaxy properties. The classical indicator F_blue (fraction of blue galaxies) proved to be a simple but powerful diagnostic tool. We studied its variation for different luminosity and mass selected galaxy samples. Using rest-frame B-band selected samples, the groups galaxy population exhibits significant blueing as redshift increases, but maintains a lower F_blue with respect both to the global and the isolated galaxy population. However moving to mass selected samples it becomes apparent that such differences are largely due to the biased view imposed by the B-band luminosity selection, being driven by the population of lower mass, bright blue galaxies for which we miss the redder, equally low mass, counterparts. By focusing the analysis on narrow mass bins such that mass segregation becomes negligible we find th...

    2010-01-01

    Structured P2P overlays provide a framework for building distributed applications that are self-configuring, scalable, and resilient to node failures. Such systems have been successfully adopted in large-scale Internet services such as content delivery networks and file sharing; however, widespread adoption in small/medium scales has been limited due in part to security concerns and difficulty bootstrapping in NAT-constrained environments. Nonetheless, P2P systems can be designed to provide guaranteed lookup times, NAT traversal, point-to-point overlay security, and distributed data stores. In this paper we propose a novel way of creating overlays that are both secure and private and a method to bootstrap them using a public overlay. Private overlay nodes use the public overlay's distributed data store to discover each other, and the public overlay's connections to assist with NAT hole punching and as relays providing STUN and TURN NAT traversal techniques. The security framework utilizes groups, which are cr...

    2004-01-01

    We present HI synthesis maps of the edge-on starburst NGC 5433 and its environment, obtained with the VLA in its C and D configurations. The observations and spectral model residuals of the main disc emission in NGC 5433 reveal 3 extraplanar features. We associate 2 of these features with coherent extraplanar extensions across multiple spectral channels in our data, including a complete loop in position-velocity space. Interpreting the latter as an expanding shell we derive a corresponding input energy of 2 x 10^54 ergs, comparable to that for the largest supershells found in the Galaxy and those in other edge-on systems. NGC 5433 is in a richer environment than previously thought. We confirm that KUG 1359+326 is a physical companion to NGC 5433 and find two new faint companions, both with Minnesota Automated Plate Scanner identifications, that we label SIS-1 and SIS-2. Including the more distant IC 4357, NGC 5433 is the dominant member of a group of at least 5 galaxies, spanning over 750 kpc in a filamentary...

    Microbial communities in glacial ecosystems are diverse, active, and subjected to strong viral pressures and infection rates. In this study we analyse putative virus genomes assembled from three dsDNA viromes from cryoconite hole ecosystems of Svalbard and the Greenland Ice Sheet to assess the potential hosts and functional role viruses play in these habitats. We assembled 208 million reads from the virus-size fraction and developed a procedure to select genuine virus scaffolds from cellular contamination. Our curated virus library contained 546 scaffolds up to 230 Kb in length, 54 of which were circular virus consensus genomes. Analysis of virus marker genes revealed a wide range of viruses had been assembled, including bacteriophages, cyanophages, nucleocytoplasmic large DNA viruses and a virophage, with putative hosts identified as Cyanobacteria, Alphaproteobacteria, Gammaproteobacteria, Actinobacteria, Firmicutes, eukaryotic algae and amoebae. Whole genome comparisons revealed the majority of circular genome scaffolds (CGS) formed 12 novel groups, two of which contained multiple phage members with plasmid-like properties, including a group of phage-plasmids possessing plasmid-like partition genes and toxin-antitoxin addiction modules to ensure their replication and a satellite phage-plasmid group. Surprisingly we also assembled a phage that not only encoded plasmid partition genes, but a clustered regularly interspaced short palindromic repeat (CRISPR)/Cas adaptive bacterial immune system. One of the spacers was an exact match for another phage in our virome, indicating that in a novel use of the system, the lysogen was potentially capable of conferring immunity on its bacterial host against other phage. Together these results suggest that highly novel and diverse groups of viruses are present in glacial environments, some of which utilize very unusual life strategies and genes to control their replication and maintain a long-term relationship with their hosts

    Lipophilic contaminants are present in the environment and bioaccumulate in the food chain. Therefore, their intake via animal fat of various sources was assessed for three age groups of the Flemish population, participating in a large biomonitoring program of the Flemish government. In total, 1636 adolescents (14-15 years), 1186 mothers (18-44 years), and 1586 adults (50-65 years) participated in the study and completed a semi quantitative food frequency questionnaire. Individual consumption data were combined, via a so-called simple distribution approach, with recent data on polychlorinated dibenzo-p-dioxins/furans and dioxin-like polychlorinated biphenyls, measured via the chemical-activated luciferase gene expression (CALUX) bio-assay in food items available on the Flemish market. The median (95th percentile) estimated intakes of dioxin-like contaminants were 2.24 (4.61), 2.09 (4.26), and 1.74 (3.53) pg CALUX-TEQ kg(-1) bw d(-1) for, respectively adolescents, mothers and adults. These data are in the same range as those found in other European studies. The CALUX-TEQ results of respectively 59.8%, 53.7% and 36.2% of the adolescent, mother and adult population exceed the tolerable weekly intake (TWI) of 14 pg WHO-TEQ kg(-1) bw w(-1), as derived by the Scientific Committee on Food [Scientific Committee on Food, 2001. Opinion of the Scientific Committee on Food on the Risk Assessment of Dioxins and Dioxin-like PCBs in Food, CS/CNTM/DIOXIN/20 final Brussels, Belgium]. The main contributors of dioxin-like substances are fish and seafood (25-43% of the total intake), added fats (22-25% of the total intake) and dairy products (17-20% of the total intake).

  18. A Study on Group Key Agreement in Sensor Network Environments Using Two-Dimensional Arrays

    2011-08-01

    Full Text Available These days, with the emergence of the concept of ubiquitous computing, sensor networks that collect, analyze and process all the information through the sensors have become of huge interest. However, sensor network technology fundamentally has wireless communication infrastructure as its foundation and thus has security weakness and limitations such as low computing capacity, power supply limitations and price. In this paper, and considering the characteristics of the sensor network environment, we propose a group key agreement method using a keyset pre-distribution of two-dimension arrays that should minimize the exposure of key and personal information. The key collision problems are resolved by utilizing a polygonal shape’s center of gravity. The method shows that calculating a polygonal shape’s center of gravity only requires a very small amount of calculations from the users. The simple calculation not only increases the group key generation efficiency, but also enhances the sense of security by protecting information between nodes.

    Full Text Available The role of peer-group environment as an influencing factor in purchase decisions is well established. This paper broadens the above premise and studies the influence of peer-group environment on an individual's promotional choice in the context of premium promotions or freebies. Two sets of college students with distinctive peer-group settings in terms of their academic pursuit and residential details have been considered for the study. Discriminant analysis shows that higher interaction and educational orientation of group members influence the customer's promotional preference. Students pursuing professionally oriented courses had a distinctively higher preference for premium-promotions that were hedonic.

  3. Water and carboxyl group environments in the dehydration blueshift of bacteriorhodopsin.

    2000-11-01

    The proton channels of the bacteriorhodopsin (BR) proton pump contain bound water molecules. The channels connect the purple membrane surfaces with the protonated retinal Schiff base at the membrane center. Films of purple membrane equilibrated at low relative humidity display a shift of the 570 nm retinal absorbance maximum to 528 nm, with most of the change occurring below 15% relative humidity. Purple membrane films were dehydrated to defined humidities between about 50 and 4.5% and examined by Fourier transform infrared difference spectroscopy. In spectra of dehydrated-minus-hydrated purple membrane, troughs are observed at 3645 and 3550 cm-1, and peaks are observed at 3665 and 3500 cm-1. We attribute these changes to water dissociation from the proton uptake channel and the resulting changes in hydrogen bonding of water that remains bound. Also, in the carboxylic acid spectral region, a trough was observed at 1742 cm-1 and a peak at 1737 cm-1. The magnitude of the trough to peak difference between 1737 and 1742 cm-1 correlates linearly with the extent of the 528 nm pigment. This suggests that a carboxylic acid group or groups is undergoing a change in environment as a result of dehydration, and that this change is linked to the appearance of the 528 nm pigment. Dehydration difference spectra with BR mutants D96N and D115N show that the 1737-1742 cm-1 change is due to Asp 96 and Asp 115. A possible mechanism is suggested that links dissociation of water in the proton uptake channel to the environmental change at the Schiff base site.

  4. A consensus model for group decision making under interval type-2 fuzzy environment

    Institute of Scientific and Technical Information of China (English)

    Xiao-xiong ZHANG; Bing-feng GE; Yue-jin TAN

    2016-01-01

    We propose a new consensus model for group decision making (GDM) problems, using an interval type-2 fuzzy environment. In our model, experts are asked to express their preferences using linguistic terms characterized by interval type-2 fuzzy sets (IT2 FSs), because these can provide decision makers with greater freedom to express the vagueness in real-life situa-tions. Consensus and proximity measures based on the arithmetic operations of IT2 FSs are used simultaneously to guide the decision-making process. The majority of previous studies have taken into account only the importance of the experts in the aggregation process, which may give unreasonable results. Thus, we propose a new feedback mechanism that generates different advice strategies for experts according to their levels of importance. In general, experts with a lower level of importance require a larger number of suggestions to change their initial preferences. Finally, we investigate a numerical example and execute com-parable models and ours, to demonstrate the performance of our proposed model. The results indicate that the proposed model provides greater insight into the GDM process.

  5. Tidal Interaction as the origin of early-type dwarf galaxies in group environment

    2014-01-01

    We present a sample of dwarf galaxies that suffer ongoing disruption by the tidal force of nearby massive galaxies. Analysing structural and stellar population properties using the archival imaging and spectroscopic data from the Sloan Digital Sky Survey (SDSS), we find that they are likely a `smoking gun' example of the formation of early-type dwarf galaxies (dEs) in the galaxy group environment through the tidal stirring. Inner cores of these galaxies are fairly intact and the observed light profiles are well fitted with the Sersic functions, while the tidally stretched stellar halos are prominent in the outer parts. They are all located within the 50 kpc sky-projected distance from the center of host galaxies and no dwarf galaxies have relative line-of-sight velocity larger than 205 km/s to their hosts. We derive the Composite Stellar Population (CSP) properties these galaxies by fitting the SDSS optical spectra to a multiple-burst composite stellar population model. We find that these galaxies accumulate ...

    Full Text Available Abstract. The aim of the article is to consider the psychological characteristics of involvement of youth in extremist community through the Internet.Methods. The theoretical analysis and modeling were used as the main methods.Results. The Internet is described as a means and space of psychological influence on young people, which can be both positive and negative. Absorption of teenagers, boys and young men, in a virtual space essentially converts their activity and, as a result, transform the leading activity, which in turn leads to different mental tumors. Three main effects from the exposure of the Internet are found out: «the effect of the goals of drift», mythology and «the effect of excitement»; their impact on the individual in each age periods is noted. Consideration of the main motivational reasons, taking into account the specifics of building human interaction with the environment made it possible to identify and describe the main types of behavioural patterns exhibited by young people on the Internet. The degree of activity of young people in the network is described from the perspective of integrated strategies of behaviour: information blocking, changes in the distance, control, transformations. Risk groups of users, the most susceptible to extremist manipulations are designated. «Vulnerability areas» of representatives of each group are summarized and described; a step-by-step algorithm of victims’ involvement in extremist communities by recruiters is described.Scientific novelty of the present study consists in discussion of one of the most acute problems of the present – the changed conditions of a growing and socialization of younger generation; constant stay in network virtual space is an integral part of today’s existence, wherein unformed and immature person is very vulnerable to the influence of extremist content.

    A method, system, and program storage device for creating a new user account or user group with a unique identification number in a computing environment having multiple user registries is provided. In response to receiving a command to create a new user account or user group, an operating system of a clustered computing environment automatically checks multiple registries configured for the operating system to determine whether a candidate identification number for the new user account or user group has been assigned already to one or more existing user accounts or groups, respectively. The operating system automatically assigns the candidate identification number to the new user account or user group created in a target user registry if the checking indicates that the candidate identification number has not been assigned already to any of the existing user accounts or user groups, respectively.

    Full Text Available OBJECTIVE: The Somatoform Dissociation Questionnaire is a self-report questionnaire that has proven to be a reliable and valid instrument. The objectives of this study were to validate the Portuguese version and to determine its capability to distinguish patients with dissociative disorders from others with psychopathological disorders. METHOD: 234 patients answered the translated version of Somatoform Dissociation Questionnaire. The Portuguese Dissociative Disorders Interview Schedule was used to validate clinical diagnosis. Patients with dissociative disorder (n = 113 were compared to a control group of 121 patients with various anxiety and depression disorders. RESULTS: Reliability measured by Cronbach's a was 0.88. The best performance of the Portuguese form was at a cut-off point of 35, which distinguishes between dissociative disorder and neurotic disorders with a good diagnostic efficacy (sensitivity = 0.73. The somatoform dissociation was significantly more frequent in dissociative disorder patients, conversion disorder patients and post-traumatic stress disorder patients. CONCLUSIONS: These findings suggest that dissociative disorders can be differentiated from other psychiatric disorders through somatoform dissociation. The Portuguese version of the Somatoform Dissociation Questionnaire has fine psychometric features that sustain its cross-cultural validity.OBJETIVO: O objetivo deste estudo foi adaptar, validar e determinar a confiabilidade da versão portuguesa do Somatoform Dissociation Questionnaire e determinar a sua capacidade de discriminar doentes que dissociam de outros doentes.

    Full Text Available Abstract Background Support groups have proved to be effective in reducing the burden on family caregivers of dementia patients. Nevertheless, little is known about the factors that influence utilisation or quality expectations of family caregivers. These questions are addressed in the following paper. Methods The cross-sectional study was carried out as an anonymous written survey of family caregivers of dementia patients in Germany. Qualitative and quantitative data from 404 caregivers were analysed using content analysis and binary logistic regression analysis. Results The only significant predictor for utilisation is assessing how helpful support groups are for the individual care situation. Family caregivers all agree that psycho-educative orientation is a priority requirement. Conclusions In order to increase the rate of utilisation, family caregivers must be convinced of the relevant advantages of using support groups. Support groups which offer an exchange of experiences, open discussion, information and advice meet the requirements of family caregivers.

    2012-01-01

    Full Text Available Questionnaires are frequently used in quantitative marketing research and social research. A questionnaire is a series of questions asked to individuals to obtain statistically useful information about a given topic. When properly constructed and responsibly administered, questionnaires become a vital instrument by which statements can be made about specific groups or people or entire populations. They are a valuable method of collecting a wide range of information from a large number of individuals, often referred to as respondents. Adequate questionnaire construction is critical to the success of a survey. Appropriate questions, correct ordering of questions, correct scaling, or good questionnaire format can make the survey worthwhile, as it may accurately reflect the views and opinions of the participants. A useful method for checking a questionnaire and making sure it is accurately capturing the intended information is to pretest among a smaller subset of target respondents.

    There is a strong evidence in medical education literature that the learner-centred curriculum favouring the use of metacognition and self-learning is very proficient. However, ethnocultural and verbal environment may undermine learners' ability to utilise the learning strategies, leading to inefficient learning. This study aimed to investigate the personal preferences of learners in multilingual educational environment prompting the most efficient learning. The study uses qualitative focus group methodology to understand students' opinion on how educational environment influences the efficiency of medical school curriculum.

  18. Summary of presentation for research on social structure, agreement, and conflict in groups in extreme and isolated environments

    Despite a vast amount of research, little is known concerning the effect of group structure, and individuals' understanding of that structure, on conflict in Antarctic groups. The overall objective of the research discussed is to determine the interrelationships of group structure, social cognition, and group function and conflict in isolated and extreme environments. In the two decades following WWII, a large body of research focused on the physiological, psychological, and social psychological factors affecting the functioning of individuals and groups in a variety of extreme and isolated environments in both the Arctic and Antarctic. There are two primary reasons for further research of this type. First, Antarctic polar stations are considered to be natural laboratories for the social and behavioral sciences and provide an opportunity to address certain theoretical and empirical questions concerned with agreement and conflict in social groups in general and group behavior in extreme, isolated environments in particular. Recent advances in the analysis of social networks and intracultural variation have improved the methods and have shifted the theoretical questions. The research is motivated by three classes of questions: (1) What are the characteristics of the social relations among individuals working and living together in extreme and isolated environments?; (2) What do individuals understand about their group, how does that understanding develop, and how is it socially distributed?; and (3) What is the relationship between that understanding and the functioning of the social group? Answers to these questions are important if we are to advance our knowledge of how individuals and groups adapt to extreme environments. Second, although Antarctic winter-over candidates may be evaluated as qualified on the basis of individual characteristics, they may fail to adapt because of certain characteristics of the social group. Consequently, the ability of winter-over-groups

    Sinai's model of diffusion in one dimension with random local bias is studied by a real space renormalization group, which yields exact results at long times. The effects of an additional small uniform bias force are also studied. We obtain analytically the scaling form of the distribution of the position x(t) of a particle, the probability of it not returning to the origin, and the distributions of first passage times, in an infinite sample as well as in the presence of a boundary and in a finite but large sample. We compute the distribution of the meeting time of two particles in the same environment. We also obtain a detailed analytic description of the thermally averaged trajectories by computing quantities such as the joint distribution of the number of returns and of the number of jumps forward. These quantities obey multifractal scaling, characterized by generalized persistence exponents theta(g) which we compute. In the presence of a small bias, the number of returns to the origin becomes finite, characterized by a universal scaling function which we obtain. The full statistics of the distribution of successive times of return of thermally averaged trajectories is obtained, as well as detailed analytical information about correlations between directions and times of successive jumps. The two-time distribution of the positions of a particle, x(t) and x(t') with t>t', is also computed exactly. It is found to exhibit "aging" with several time regimes characterized by different behaviors. In the unbiased case, for t-t' approximately t'alpha with alpha>1, it exhibits a ln t/ln t' scaling, with a singularity at coinciding rescaled positions x(t)=x(t'). This singularity is a novel feature, and corresponds to particles that remain in a renormalized valley. For closer times alpha<1, the two-time diffusion front exhibits a quasiequilibrium regime with a ln(t-t')/ln t' behavior which we compute. The crossover to a t/t' aging form in the presence of a small bias is

    1998-07-01

    The Working group 'Chemistry of Complexing Molecules and Environment' of the Mission Environment (AG/ENV) identified themes for an original positioning of CEA on important issues of environmental research if a sufficiently strong demand appears. The research of CEA on the environment should be complementary to actions undertaken by other partners (official institutions, research organizations and industrial firms). The themes suggested are: the synthesis of new chelating molecules and new materials having specific properties, with the support of theoretical chemistry and modeling, analytical physical chemistry and speciation of species in relation to their eco-toxicity and their biogeochemical mobility in the natural environment. These themes, illustrated by examples of actions in progress at CEA or likely to be launched quickly, draw largely from recognized competences of the teams, generally developed for finalized nuclear applications: experimental, theoretical and instrumental competences.

    Full Text Available Abstract Background Food behaviours, attitudes, environments and knowledge are relevant to professionals in childhood obesity prevention, as are dietary patterns which promote positive energy balance. There is a lack of valid and reliable tools to measure these parameters. The aim of this study was to determine the reliability and relative validity of a child nutrition questionnaire assessing all of these parameters, used in the evaluation of a community-based childhood obesity prevention project. Methods The development of the 14-item questionnaire was informed by the aims of the obesity prevention project. A sub-sample of children aged 10–12 years from primary schools involved in the intervention was recruited at the project's baseline data collection (Test 1. Questionnaires were readministered (Test 2 following which students completed a 7-day food diary designed to reflect the questionnaire. Twelve scores were derived to assess consumption of fruit, vegetables, water, noncore foods and sweetened beverages plus food knowledge, behaviours, attitudes and environments. Reliability was assessed using (a the intra class correlation coefficient (ICC and 95% confidence intervals to compare scores from Tests 1 and 2 (test-retest reliability and (b Cronbach's alpha (internal consistency. Validity was assessed with Spearman correlations, bias and limits of agreement between scores from Test 1 and the 7-day diaries. The Wilcoxon signed rank test checked for significant differences between mean scores. Results One hundred and forty one students consented to the study. Test 2 (n = 134 occurred between eight and 36 days after Test 1. For 10/12 scores ICCs ranged from 0.47–0.66 (p 0.05 for 10/12 (test-retest reliability and 3/7 (validity scores.

    2017-02-01

    Full Text Available Roland Bal analyzes the strategies his research group developed to deal with the interlinked dynamics of research evaluation in a multi-disciplinary institutional environment characteristic of much STS research. Scholars in such environments constantly need to navigate and negotiate the standards of evaluation, in complex choreographies of cooperation and competition with other disciplinary groups. Bal describes strategies his group has successfully used, and how these strategies have both shifted the way research quality is assessed within the department as well as changed the way his group works and publishes. In conclusion, he describes performance management systems and research practices as co-constituted and calls for a debate on which forms of evaluation infrastructures allow for better ways of doing research in STS.

    The Zurich Environmental Study (ZENS) is based on a sample of ∼1500 galaxy members of 141 groups in the mass range ∼10{sup 12.5-14.5} M{sub ☉} within the narrow redshift range 0.05 < z < 0.0585. ZENS adopts novel approaches, described here, to quantify four different galactic environments, namely: (1) the mass of the host group halo; (2) the projected halo-centric distance; (3) the rank of galaxies as central or satellites within their group halos; and (4) the filamentary large-scale structure density. No self-consistent identification of a central galaxy is found in ∼40% of <10{sup 13.5} M{sub ☉} groups, from which we estimate that ∼15% of groups at these masses are dynamically unrelaxed systems. Central galaxies in relaxed and unrelaxed groups generally have similar properties, suggesting that centrals are regulated by their mass and not by their environment. Centrals in relaxed groups have, however, ∼30% larger sizes than in unrelaxed groups, possibly due to accretion of small satellites in virialized group halos. At M > 10{sup 10} M{sub ☉}, satellite galaxies in relaxed and unrelaxed groups have similar size, color, and (specific) star formation rate distributions; at lower galaxy masses, satellites are marginally redder in relaxed relative to unrelaxed groups, suggesting quenching of star formation in low-mass satellites by physical processes active in relaxed halos. Overall, relaxed and unrelaxed groups show similar stellar mass populations, likely indicating similar stellar mass conversion efficiencies. In the enclosed ZENS catalog, we publish all environmental diagnostics as well as the galaxy structural and photometric measurements described in companion ZENS papers II and III.

    2011-01-01

    Galaxy star formation rates (SFRs) are sensitive to the local environment; for example, the high-density regions at the cores of dense clusters are known to suppress star formation. It has been suggested that galaxy transformation occurs largely in groups, which are the intermediate step in density between field and cluster environments. In this paper, we use deep MIPS 24 micron observations of intermediate-redshift (0.3 10.5, corresponding to SFR > 2.7 M_sun/yr. We find that the group and field galaxies have different distributions of morphologies and mass. However, individual group galaxies have star-forming properties comparable to those of field galaxies of similar mass and morphology; that is, the group environment does not appear to modify the properties of these galaxies directly. There is a relatively large number of massive early-type group spirals, along with E/S0 galaxies, that are forming stars above our detection limit. These galaxies account for the nearly comparable level of star-forming activ...

    Understanding the interaction between galaxies and their surroundings is central to building a coherent picture of galaxy evolution. Here we use Galaxy Evolution Explorer imaging of a statistically representative sample of 23 galaxy groups at z Almost-Equal-To 0.06 to explore how local and global group environments affect the UV properties and dust-corrected star formation rates (SFRs) of their member galaxies. The data provide SFRs out to beyond 2R{sub 200} in all groups, down to a completeness limit and limiting galaxy stellar mass of 0.06 M{sub Sun} yr{sup -1} and 1 Multiplication-Sign 10{sup 8} M{sub Sun }, respectively. At fixed galaxy stellar mass, we find that the fraction of star-forming group members is suppressed relative to the field out to an average radius of R Almost-Equal-To 1.5 Mpc Almost-Equal-To 2R{sub 200}, mirroring results for massive clusters. For the first time, we also report a similar suppression of the specific SFR within such galaxies, on average by 40% relative to the field, thus directly revealing the impact of the group environment in quenching star formation within infalling galaxies. At fixed galaxy density and stellar mass, this suppression is stronger in more massive groups, implying that both local and global group environments play a role in quenching. The results favor an average quenching timescale of {approx}> 2 Gyr and strongly suggest that a combination of tidal interactions and starvation is responsible. Despite their past and ongoing quenching, galaxy groups with more than four members still account for at least {approx}25% of the total UV output in the nearby universe.

    The Zurich Environmental Study (ZENS) is designed to compare the dependence of z=0 galaxy structural and stellar populations diagnostics at constant stellar mass on four measures of the environment: the mass of the host group halos; the projected distance from the center of the halo; the rank of galaxies as central or satellites; and the filamentary LSS density on which the groups reside. The complete ZENS sample contains 1630 galaxies in 141~10^{12.5-14}M_sun 2PIGG groups at z~0.06. We outline the survey motivation and describe novel approaches to quantify the environments of galaxies. We introduce a set of self-consistency checks to define the group centers and to rank galaxies as centrals or satellites, and describe an Nth-nearest-neighbor approach to determine the LSS density field using groups as tracers. We publish the ZENS catalogue of galaxy and group properties, which combines the environmental diagnostics presented here with structural and SED measurements described in subsequent papers.

    2005-04-01

    Unlike the traditional ``sage-on-the-stage'' configuration of many K-12 classrooms, the group learning or ``guide-on-the-side'' configuration does not involve communication between a teacher in front of a seated class of 20 to 30 students. Instead, it can involve, most of the time, communication between the teacher and each of several small groups of students interacting, aurally, with each other. To maintain the desired 15 dB signal-to-noise ratio intended as the rationale for the ANSI standard, S12.60-2002 on classroom acoustics, the ``noise'' heard by participants in one of the groups is likely to include the speech levels generated by the participants in the other groups as well as the background noise in the unoccupied classroom. Thus, specification of the speech level within (i.e. the ``signal''), and between (i.e. part of the ``noise'') the learning groups, must be considered. Data available to evaluate these speech levels are reviewed and possible models considered to account for the Lombard effect for voice levels of both the teacher and the students. Some of the gaps in these data are suggested as a challenge to stimulate further studies on speech levels of teachers and students in a wide range of communication conditions.

    A simulation for flight of international crew on space station took place in Moscow from July 1999 to April 2000 (SFINCS) at the State Biomedical Institute of Russia (IBMP) isolation chambers. Objectives of this study were to identify concepts of psychosocial adaptation and of social interactions to develop an explanation of the transcultural group performance. Method: constructivist epistemology with grounded theory research and fourth generation evaluation were used. Data on processes and interactions were gathered during 110 days of confinement as a subject and extended to 240 days as an outside scientist. Results indicate that coping is influenced by usual coping strategies and coping behaviors inside. Several stresses and human factor issues were identified altering well being and performance inside the chambers. Enabling and limiting forces are discussed. A theory on transcultural group performance is proposed. Issues are raised that appear critical to selection, training and group performance.

    A Web survey of 1,715 college students was conducted to examine Facebook Groups users' gratifications and the relationship between users' gratifications and their political and civic participation offline. A factor analysis revealed four primary needs for participating in groups within Facebook: socializing, entertainment, self-status seeking, and information. These gratifications vary depending on user demographics such as gender, hometown, and year in school. The analysis of the relationship between users' needs and civic and political participation indicated that, as predicted, informational uses were more correlated to civic and political action than to recreational uses.

    It is estimated that employers spend more than 75 billion dollars annually on obesity-attributable health care. Interventions to reduce or prevent the risk of obesity are increasingly common at worksites and include health fairs, weight loss and nutrition classes, and fitness programs. However, many companies lack the resources to plan and implement these types of programs. Environmental approaches offer companies a low-cost option. A community-based participatory research model was used to bring academic researchers, human resources personnel, and health department educators together to plan and implement an environmental program aimed at increasing healthy eating and physical activity at four small manufacturing companies. The Diffusion of Innovations Theory guided the development of focus group questions. A focus group study was then conducted to gather information from employees and managers at these four companies. The questions identified workplace strategies that would aid in reducing barriers and developing appropriate communication channels to enhance employee participation in the program. The researchers identified themes from manager and employee focus groups regarding the following five environmental components: signs, walking paths, food changes, educational strategies, and advisory groups.

    In this letter we present, for the first time, a study of star formation rate, gas fraction and galaxy morphology of a constrained simulation of the Milky Way (MW) and Andromeda (M31) galaxies, compared to other MW-mass galaxies. By combining with unconstrained simulations we cover a sufficient volume to compare these galaxies environmental densities ranging from the field to that of the Local Group (LG). This is particularly relevant as it has been shown that, quite generally, galaxy properties depend intimately upon their environment, most prominently when galaxies in clusters are compared to those in the field. For galaxies in loose groups such as the LG, however, environmental effects have been less clear. We consider the galaxy's environmental density in spheres of 1200 kpc (comoving) and find that whilst environment does not appear to directly affect morphology, there is a positive trend with star formation rates. This enhancement in star formation occurs systematically for galaxies in higher density en...

    In this Letter, we present, for the first time, a study of star formation rate (SFR), gas fraction, and galaxy morphology of a constrained simulation of the Milky Way (MW) and Andromeda (M31) galaxies compared to other MW-mass galaxies. By combining with unconstrained simulations, we cover a sufficient volume to compare these galaxies’ environmental densities ranging from the field to that of the Local Group (LG). This is particularly relevant as it has been shown that, quite generally, galaxy properties depend intimately upon their environment, most prominently when galaxies in clusters are compared to those in the field. For galaxies in loose groups such as the LG, however, environmental effects have been less clear. We consider the galaxy’s environmental density in spheres of 1200 kpc (comoving) and find that while environment does not appear to directly affect morphology, there is a positive trend with SFRs. This enhancement in star formation occurs systematically for galaxies in higher density environments, regardless whether they are part of the LG or in filaments. Our simulations suggest that the richer environment at megaparsec scales may help replenish the star-forming gas, allowing higher specific SFRs in galaxies such as the MW.

    The goal of this ongoing comprehensive osteoporosis disease management initiative is to provide the adult primary care physicians' (PCPs) offices with a program enabling them to systematically identify and manage their population for osteoporosis. For over six years, Hill Physicians Medical Group (Hill Physicians) has implemented multiple strategies to develop a best practice for identifying and treating members who were candidates for osteoporosis therapy. Numerous tools were used to support this disease management effort, including: evidence-based clinical practice guidelines, patient education sessions, the Simple Calculated Osteoporosis Risk Estimation (SCORE) questionnaire tool, member specific reports for PCPs, targeted member mailings, office-based Peripheral Instantaneous X-ray Imaging (PIXI) test and counseling, dual x-ray absorptiometry (DEXA) scan guidelines, and web-based Electronic Simple Calculated Osteoporosis Risk Estimation (eSCORE) questionnaire tools. Hill Physicians tabulated results for patients who completed 2649 SCORE tests, screened 978 patients with PIXI tests, and identified 338 osteopenic and 124 osteoporotic patients. The preliminary results of this unique six-year ongoing educational initiative are slow but promising. New physician offices express interest in participating and those offices that have participated in the program continue to screen for osteoporosis. Hill Physicians' message is consistent and is communicated to the physicians repeatedly in different ways in accordance with the principles of educational outreach. Physicians who have conducted the program have positive feedback from their patients and office staff and have begun to communicate their experience to their peers.

    Understanding the interaction between galaxies and their surroundings is central to building a coherent picture of galaxy evolution. Here we use GALEX imaging of a statistically representative sample of 23 galaxy groups at z=0.06 to explore how local and global group environment affect the UV properties and dust-corrected star formation rates of their member galaxies. The data provide star formation rates out to beyond 2R_200 in all groups, down to a completeness limit and limiting galaxy stellar mass of 0.06 M_sun/yr and 10^8 M_sun, respectively. At fixed galaxy stellar mass, we find that the fraction of star-forming group members is suppressed relative to the field out to an average radius of R ~ 1.5 Mpc ~ 2R_200, mirroring results for massive clusters. For the first time we also report a similar suppression of the specific star formation rate within such galaxies, on average by 40% relative to the field, thus directly revealing the impact of the group environment in quenching star formation within infallin...

  8. Fundamental parameters of FR II radio galaxies and their impact on groups and clusters' environments

    Kapinska, Anna D

    2012-01-01

    Radio galaxies are among the largest and most powerful single objects known and are found at variety of redshifts, hence they are believed to have had a significant impact on the evolving Universe. Their relativistic jets inject considerable amounts of energy into the environments in which the sources reside; thus the knowledge of the fundamental properties (such as kinetic luminosities, lifetimes and ambient gas densities) of these sources is crucial for understanding AGN feedback in galaxy clusters. In this work, we explore the intrinsic and extrinsic fundamental properties of Fanaroff-Riley II (FR II) objects through the construction of multidimensional Monte Carlo simulations which use complete, flux limited radio catalogues and semi-analytical models of FR IIs' time evolution to create artificial samples of radio galaxies. This method allows us to set better limits on the confidence intervals of the intrinsic and extrinsic fundamental parameters and to investigate the total energy produced and injected t...

    Full Text Available A study was performed in the Microbial Physiology course to increase students’ self-awareness of their misconceptions, promote sound research techniques, develop written and oral communication skills, stimulate metacognition, and improve teamwork and interpersonal relationship skills. The transformation in the teaching methodology included using cooperative learning, field trips, and portfolios that targeted diverse learning styles to challenge students in creative ways and to help prepare them for future careers. The entire structure of the class was modified by introducing in-class portfolios to form a constructivist environment in which the discussion and lecture topic of the day were built on prior student knowledge. Based on evaluations, students were very pleased with the new teaching and learning process and learned more content than in the more traditional class. They also felt better able to reflect on their learning.

    Group II introns are catalytic RNAs and mobile retrotransposable elements known to be present in the genomes of some nonmarine bacteria and eukaryotic organelles. Here we report the discovery of group II introns in a bacterial mat sample collected from a deep-sea hydrothermal vent near 9 degrees N on the East Pacific Rise. One of the introns was shown to self-splice in vitro. This is the first example of marine bacterial introns from molecular population structure studies of microorganisms that live in the proximity of hydrothermal vents. These types of mobile genetic elements may prove useful in improving our understanding of bacterial genome evolution and may serve as valuable markers in comparative studies of bacterial communities.

    The "Cave of Crystals" (aka 'Naica') in Chihuahua Mexico is a natural unique subterranean ecosystem which mainly consists of crystals made of calcium sulfate. The main system of caves are found at a depth of 300 meters (m) below sea level with crystals that range in size from a few centimeters to 15 m. The crystals date from nearly 400,000 years old and are thought to be formed when the cave was fully covered by water. At present time, this place shows a nearly constant temperature of 55 °C over the year and a humidity of 100 % which makes this place incomparable and unbearable to animal and/or human life. In the present study, two actinobacterial groups were isolated from within this system of caves and subjected to a systematic study to establish their phylogenetic relationship to microorganisms belonging to this vast group of Gram positive bacteria. Phenotypic properties, chemotaxonomic and 16S rRNA gene sequencing show that the microorganisms are members of the family Pseudonocardiaceae and are most closely related to the genus Prauserella. The present study is the first to report the isolation and presence of Actinobacteria or any other microbial form of life in this exceptional place. Moreover, this unexpected biodiversity can also provide an insight of the antibiotic resistome present in the isolates reported in this study.

    Cultural and personal traits will become important as the number of short-duration spaceflights of international crews supporting the International Space Station (ISS) increases and more people begin staying aboard ISS for longer durations. This project investigated the interpersonal and personal changes of Japanese subjects during a 1-wk stay in the Japanese Experiment Module. The Giebetaen Test (GT) was used to determine if the cultural background and personality traits of the subjects become more explicit and stronger during isolation. Six males and two females aged 22-28 yr participated in the study. They stayed 7 d in the isolation chamber at the National Space Development Agency of Japan (NASDA). The GT was chosen as an individual and group diagnostic instrument; it was administrated four times during, and one time after, isolation. According to the GT-self-picture, subjects exhibited a change toward negative social resonance and social withdrawal. Subgroups formed but caused no isolation or tension. The GT-foreign-pictures showed that the judgment of other subjects changed toward hedonic and permeability directions. The common interpersonal relationships of the Japanese subjects influenced the group dynamics. These relationships tend to be integrative and tend to support the network and value systems, emphasizing connectedness and minimizing differences. The cultural background became more explicit and stronger during isolation. Based on this, isolation studies with international crews and intercultural training will be necessary for international crews performing both short- and long-duration missions.

    This collection of papers is the result of a symposium sponsored by NATO's Defense Research Group Panel VIII in the Spring of 1985. The symposium came into being when it became obvious to the NATO countries that research, development and utilization of advanced technologies for training was the best means of increasing both training effectiveness and efficiency. This symposium was the second in a series of three devoted to training. The series was structured to cover all aspects of training. The first series addressed the value of training, the second one dealt with the application of training technologies and the third and last of the series focused on academic issues concerned with the effect of prior learning on subsequent learning. The fact that a major American publisher has determined that computer based instruction is the technology of greatest interest to the NATO community is not surprising. Advances in microprocessor technology have revolutionized both how and where we train. During this symposium t...

  14. A Binaural Grouping Model for Predicting Speech Intelligibility in Multitalker Environments

    Directory of Open Access Journals (Sweden)

    2016-09-01

    Full Text Available Spatially separating speech maskers from target speech often leads to a large intelligibility improvement. Modeling this phenomenon has long been of interest to binaural-hearing researchers for uncovering brain mechanisms and for improving signal-processing algorithms in hearing-assistive devices. Much of the previous binaural modeling work focused on the unmasking enabled by binaural cues at the periphery, and little quantitative modeling has been directed toward the grouping or source-separation benefits of binaural processing. In this article, we propose a binaural model that focuses on grouping, specifically on the selection of time-frequency units that are dominated by signals from the direction of the target. The proposed model uses Equalization-Cancellation (EC processing with a binary decision rule to estimate a time-frequency binary mask. EC processing is carried out to cancel the target signal and the energy change between the EC input and output is used as a feature that reflects target dominance in each time-frequency unit. The processing in the proposed model requires little computational resources and is straightforward to implement. In combination with the Coherence-based Speech Intelligibility Index, the model is applied to predict the speech intelligibility data measured by Marrone et al. The predicted speech reception threshold matches the pattern of the measured data well, even though the predicted intelligibility improvements relative to the colocated condition are larger than some of the measured data, which may reflect the lack of internal noise in this initial version of the model.

  17. Gender differences in an elementary school learning environment: A study on how girls learn science in collaborative learning groups

    Science.gov (United States)

    Greenspan, Yvette Frank

    Girls are marked by low self-confidence manifested through gender discrimination during the early years of socialization and culturalization (AAUW, 1998). The nature of gender bias affects all girls in their studies of science and mathematics, particularly in minority groups, during their school years. It has been found that girls generally do not aspire in either mathematical or science-oriented careers because of such issues as overt and subtle stereotyping, inadequate confidence in ability, and discouragement in scientific competence. Grounded on constructivism, a theoretical framework, this inquiry employs fourth generation evaluation, a twelve-step evaluative process (Guba & Lincoln, 1989). The focus is to discover through qualitative research how fifth grade girls learn science in a co-sexual collaborative learning group, as they engage in hands-on, minds-on experiments. The emphasis is centered on one Hispanic girl in an effort to understand her beliefs, attitudes, and behavior as she becomes a stakeholder with other members of her six person collaborative learning group. The intent is to determine if cultural and social factors impact the learning of scientific concepts based on observations from videotapes, interviews, and student opinion questionnaires. QSR NUD*IST 4, a computer software program is utilized to help categorize and index data. Among the findings, there is evidence that clearly indicates girls' attitudes toward science are altered as they interact with other girls and boys in a collaborative learning group. Observations also indicate that cultural and social factors affect girls' performance as they explore and discover scientific concepts with other girls and boys. Based upon what I have uncovered utilizing qualitative research and confirmed according to current literature, there seems to be an appreciable impact on the way girls appear to learn science. Rooted in the data, the results mirror the conclusions of previous studies, which

    The Late Paleocene-Early Eocene phosphorites of the Metlaoui Group in Tunisia are a world-class phosphate resource. We review the characteristics of phosphorites deposited in three areas: the Northern Basins; Eastern Basins; and Gafsa-Metlaoui Basin. Comprehensive new bulk rock elemental data are presented, together with complementary mineralogical and mineral chemical results. Carbonate fluorapatite (francolite) constitutes the dominant mineral phase in the deposits. Phosphorite samples are enriched in Cd, Sr, U, rare-earth elements and Y, together with environmentally diagnostic trace elements that provide detrital (Cr, Zr), productivity (Cu, Ni, Zn) and redox (Mo, V) proxies. Suboxic bottom-water conditions predominated, with suboxic to anoxic porewaters accompanying francolite precipitation. Phosphorite deposition occurred under increasingly arid climate conditions, accompanying global Paleocene-Eocene warming. The Northern Basins show the strongest Tethys Ocean influence, with surface seawater rare-earth element signatures consistently developed in the phosphorites. Bed-scale compositional variation indicates relatively unstable environmental conditions and episodes of sediment redeposition, with varying detrital supply and a relatively wet local climate. Glauconitic facies in the Northern Basins and the more isolated evaporite-associated phosphorites in the dryer Eastern Basins display the greatest diagenetic influences. The phosphorite - organic-rich marl - diatom-bearing porcelanite facies association in the Gafsa-Metlaoui Basin represents the classic coastal upwelling trinity. Modified Tethyan waters occurred within the Basin during phosphorite deposition, with decreasing marine productivity from NW to SE evidenced by systematically falling enrichment factors for Cu, Ni, Cd and Zn in the phosphorites. Productivity declined in concert with increasing basin isolation during the deposition of the commercial phosphorite beds in the latest Paleocene to earliest

    Hickson Compact Groups (HCGs) are among the densest galaxy environments of the local universe. To examine the effects of the environment on the infrared properties of these systems, we present an analysis of Spitzer and ISO mid-infrared imaging as well as deep ground based near-infrared imaging of 14 HCGs containing a total of 69 galaxies. Based on mid-infrared color diagnostics we identify the galaxies which appear to host an active nucleus, while using a suite of templates, we fit the complete infrared spectral energy distribution for each group member. We compare our estimates of galaxy mass, star formation rate, total infrared luminosities, and specific star formation rates (sSFR) for our HCG sample, to samples of isolated galaxies and interacting pairs and find that overall there is no discernible difference among them. However, HCGs which can be considered as dynamically "old", host late-type galaxies with a slightly lower sSFR than the one found in dynamically "young" groups. This could be attributed t...

    2017-08-01

    We make use of a catalog of 1600 Pan-STARRS1 groups produced by the probability friends-of-friends algorithm to explore how the galaxy properties, i.e., the specific star formation rate (SSFR) and quiescent fraction, depend on stellar mass and group-centric radius. The work is the extension of Lin et al. In this work, powered by a stacking technique plus a background subtraction for contamination removal, a finer correction and more precise results are obtained than in our previous work. We find that while the quiescent fraction increases with decreasing group-centric radius, the median SSFRs of star-forming galaxies in groups at fixed stellar mass drop slightly from the field toward the group center. This suggests that the main quenching process in groups is likely a fast mechanism. On the other hand, a reduction in SSFRs by ˜0.2 dex is seen inside clusters as opposed to the field galaxies. If the reduction is attributed to the slow quenching effect, the slow quenching process acts dominantly in clusters. In addition, we also examine the density-color relation, where the density is defined by using a sixth-nearest-neighbor approach. Comparing the quiescent fractions contributed from the density and radial effect, we find that the density effect dominates the massive group or cluster galaxies, and the radial effect becomes more effective in less massive galaxies. The results support mergers and/or starvation as the main quenching mechanisms in the group environment, while harassment and/or starvation dominate in clusters.

    As the aluminum (Al) metallization process was replaced with copper (Cu), the damascene process was introduced, which required the planarization step to eliminate over-deposited Cu with Chemical Mechanical Polishing (CMP) process. In this study, the verification of the corrosion inhibitors, one of the Cu CMP slurry components, was conducted to find out the tendency regarding the carboxyl and amino functional group in neutral environment. Through the results of etch rate, removal rate, and chemical ability of corrosion inhibitors based on 1H-1,2,4-triazole as the base corrosion inhibitor, while the amine functional group presents high Cu etching ability, carboxyl functional group shows lower Cu etching ability than base-corrosion inhibitor which means that it increases passivation effect by making strong passivation layer. It implies that the corrosion inhibitor with amine functional group was proper to apply for 1st Cu CMP slurry owing to the high etch rate and with carboxyl functional group was favorable for the 2nd Cu CMP slurry due to the high Cu removal rate/dissolution rate ratio.

    Phytoplankton and environment factors were investigated in 2015 and phytoplankton functional groups were used to understand their temporal and spatial distribution and their driving factors in Wanfeng Reservoir. Seventeen functional groups (B, D, E, F, G, J, Lo, MP, P, S1, T, W1, W2, X1, X2, Xph, Y) were identified based on 34 species. The dominant groups were: J/B/P/D in dry season, X1/J/Xph/G/T in normal season and J in flood season. Phytoplankton abundance ranged from 5.33×104 cells/L to 3.65×107 cells/L, with the highest value occurring in flood season and lowest in dry season. The vertical profile of dominant groups showed little differentiation except for P, which dominated surface layers over 20 m as a result of mixing water masses and higher transparency during dry season. However, the surface waters presented higher values of phytoplankton abundance than other layers, possibly because of greater irradiance. The significant explaining variables and their ability to describe the spatial distribution of the phytoplankton community in RDA differed seasonally as follows: dry season, NH4-N, NO3-N, NO2-N, TN:TP ratio and transparency (SD); normal season, temperature (WT), water depth, TN, NH4-N and NO3-N; flood season, WT, water depth, NO3-N and NO2-N. Furthermore, nitrogen, water temperature, SD and water depth were significant variables explaining the variance of phytoplankton communities when datasets included all samples. The results indicated that water physical conditions and hydrology were important in phytoplankton community dynamics, and nitrogen was more important than phosphorus in modifying phytoplankton communities. Seasonal differences in the relationship between the environment and phytoplankton community should be considered in water quality management.

    Full Text Available BACKGROUND: Relationships between the neighborhood environment and children's physical activity have been well documented in Western countries but are less investigated in ultra-dense Asian cities. The aim of this study was to identify the environmental facilitators and barriers of physical activity behaviors among Hong Kong Chinese children using nominal group technique. METHODS: Five nominal groups were conducted among 34 children aged 10-11 years from four types of neighborhoods varying in socio-economic status and walkability in Hong Kong. Environmental factors were generated by children in response to the question "What neighborhood environments do you think would increase or decrease your willingness to do physical activity?" Factors were prioritized in order of their importance to children's physical activity. RESULTS: Sixteen unique environmental factors, which were perceived as the most important to children's physical activity, were identified. Factors perceived as physical activity-facilitators included "Sufficient lighting", "Bridge or tunnel", "Few cars on roads", "Convenient transportation", "Subway station", "Recreation grounds", "Shopping malls with air conditioning", "Fresh air", "Interesting animals", and "Perfume shop". Factors perceived as physical activity-barriers included "People who make me feel unsafe", "Crimes nearby", "Afraid of being taken or hurt at night", "Hard to find toilet in shopping mall", "Too much noise", and "Too many people in recreation grounds". CONCLUSIONS: Specific physical activity-related environmental facilitators and barriers, which are unique in an ultra-dense city, were identified by Hong Kong children. These initial findings can inform future examinations of the physical activity-environment relationship among children in Hong Kong and similar Asian cities.

    Full Text Available Abstract Background The Healthy Options for Nutrition Environments in Schools (Healthy ONES study was an evidence-based public health (EBPH randomized group trial that adapted the Institute for Healthcare Improvement’s (IHI rapid improvement process model to implement school nutrition policy and environmental change. Methods A low-income school district volunteered for participation in the study. All schools in the district agreed to participate (elementary = 6, middle school = 2 and were randomly assigned within school type to intervention (n = 4 and control (n =4 conditions following a baseline environmental audit year. Intervention goals were to 1 eliminate unhealthy foods and beverages on campus, 2 develop nutrition services as the main source on campus for healthful eating (HE, and 3 promote school staff modeling of HE. Schools were followed across a baseline year and two intervention years. Longitudinal assessment of height and weight was conducted with second, third, and sixth grade children. Behavioral observation of the nutrition environment was used to index the amount of outside foods and beverages on campuses. Observations were made monthly in each targeted school environment and findings were presented as items per child per week. Results From an eligible 827 second, third, and sixth grade students, baseline height and weight were collected for 444 second and third grade and 135 sixth grade students (51% reach. Data were available for 73% of these enrolled students at the end of three years. Intervention school outside food and beverage items per child per week decreased over time and control school outside food and beverage items increased over time. The effects were especially pronounced for unhealthy foods and beverage items. Changes in rates of obesity for intervention school (28% baseline, 27% year 1, 30% year 2 were similar to those seen for control school (22% baseline, 22% year 1, 25% year 2 children

    Despite a significant civilization advancement, parasitic diseases still pose a serious diagnostic and therapeutic problem. Children's susceptibility to these infections stems from their immature immune system and lack of basic hygiene routines. The objective of the study was to evaluate the level of knowledge which parents of preschool children's possess about parasitic diseases in their children's environment. The study was carried out in the group of 151 parents of preschool children living both in the city and in the country. The survey was carried out by means of a diagnostic poll with the application of a self-designed research questionnaire. To make the evaluation even more objective, a special scale was created in which parents could score points for their answers (0 - wrong answer, 1 - correct answer). The total number of points ranging from 0 to 9 indicated an unsatisfactory level of knowledge, from 10 to 13 - satisfactory level, from 14 to 16 - good level and from 17 to 20 - very good level of parents' awareness. The results of the study reveal that the level of parents' knowledge about parasitic diseases is only satisfactory. A statistically significant relationship was observed between the variables such as education and sex. The higher education, the higher level of knowledge. Moreover, women were more knowledgeable in the field of parasitic diseases than men were. Financial status of the family did not influence the level of parents' awareness. Well-planned educational programmes might have a positive influence on developing proper hygiene routines in families, which, in turn, will limit the risk of spreading parasitoses in the population of children.

    the group of completely resected stage IIIA-N2 non-small cell lung cancer patients (NSCLC) is considered to be heterogeneous in various aspects including survival and the recurrent pattern. In the present study, we attempted to clarify the factors which separate these patients into high and low risk groups based on the survival and local recurrence. a questionnaire survey on the survival and local recurrence of non-small cell lung cancer patients with pathological stage IIIA-N2 disease who underwent a complete resection from January 1992 to December 1993 was performed by the Japan Clinical Oncology Group as of July 1999. The information on the survival of 406 patients and that of local recurrence in 332 of them was available. the 5-year survival of the 406 patients was 31.0%. In a univariate analysis, the age, clinical and pathological T status, number of N2 stations, pathological N1 disease, operative modality and postoperative radiotherapy were all found to be important prognostic factors. Clinical N2 disease marginally influenced the survival (P=0.07). In a multivariate analysis of these variables including clinical N2 disease, the survival was significantly worse in the case of multiple N2 stations (hazard ratio=1.741), the presence of pathological N1 disease (1.403), pathological T2 or 3 disease (1.399) and an age older than 65 (1.327). The rate of freedom from any local recurrence at the bronchial stump, or in the hilar, mediastinal or supraclavicular lymph nodes at 5 years was 64%. In a univariate analysis of the freedom from local recurrence, the clinical N status, pathological T status, pathological N1 disease and number of N2 stations were all found to be important prognostic factors. A multivariate analysis revealed the freedom from local recurrence to be adversely influenced by multiple N2 stations (hazard ratio=2.05), and the presence of either clinical N1 or 2 (1.733) disease. The 5-year survival and the rate of freedom from local recurrence at 5

    We explore the growth of < 10^7 Msun black holes that reside at the centers of spiral and field dwarf galaxies in a Local Group type of environment. We use merger trees from a cosmological N-body simulation known as Via Lactea II (VL-2) as a framework to test two merger-driven semi-analytic recipes for black hole growth that include dynamical friction, tidal stripping, and gravitational wave recoil in over 20,000 merger tree realizations. First, we apply a Fundamental Plane limited (FPL) model to the growth of Sgr A*, which drives the central black hole to a maximum mass limited by the Black Hole Fundamental Plane after every merger. Next, we present a new model that allows for low-level Prolonged Gas Accretion (PGA) during the merger. We find that both models can generate a Sgr A* mass black hole. We predict a population of massive black holes in local field dwarf galaxies - if the VL-2 simulation is representative of the growth of the Local Group, we predict up to 35 massive black holes (< 10^6 Msun) ...

    A questionnaire was developed for the purpose of measuring Baumrind's (1971) permissive, authoritarian, and authoritative parental authority prototypes. It consists of 30 items per parent and yields permissive, authoritarian, and authoritative scores for both the mother and the father; each of these scores is derived from the phenomenological appraisals of the parents' authority by their son or daughter. The results of several studies have supported the Parental Authority Questionnaire as a psychometrically sound and valid measure of Baumrind's parental authority prototypes, and they have suggested that this questionnaire has considerable potential as a valuable tool in the investigation of correlates of parental permissiveness, authoritarianism, and authoritativeness.

    Full Text Available Abstract Background Viruses are known to be the most abundant organisms on earth, yet little is known about their collective origin and evolutionary history. With exceptionally high rates of genetic mutation and mosaicism, it is not currently possible to resolve deep evolutionary histories of the known major virus groups. Metagenomics offers a potential means of establishing a more comprehensive view of viral evolution as vast amounts of new sequence data becomes available for comparative analysis. Results Bioinformatic analysis of viral metagenomic sequences derived from a hot, acidic lake revealed a circular, putatively single-stranded DNA virus encoding a major capsid protein similar to those found only in single-stranded RNA viruses. The presence and circular configuration of the complete virus genome was confirmed by inverse PCR amplification from native DNA extracted from lake sediment. The virus genome appears to be the result of a RNA-DNA recombination event between two ostensibly unrelated virus groups. Environmental sequence databases were examined for homologous genes arranged in similar configurations and three similar putative virus genomes from marine environments were identified. This result indicates the existence of a widespread but previously undetected group of viruses. Conclusions This unique viral genome carries implications for theories of virus emergence and evolution, as no mechanism for interviral RNA-DNA recombination has yet been identified, and only scant evidence exists that genetic exchange occurs between such distinct virus lineages.

    Full Text Available Teacher recruitment is a multi-criteria group decisionmaking process involving subjectivity, imprecision, and fuzziness that can be suitably represented by neutrosophic sets. Neutrosophic set, a generalization of fuzzy sets is characterized by a truth-membership function, falsity-membership function and an indeterminacy-membership function. These functions are real standard or non-standard subsets of ] 0-, 1+[ .There is no restriction on the sum of the functions, so the sum lies between ]0-, 3+[. A neutrosophic approach is a more general and suitable way to deal with imprecise information, when compared to a fuzzy set. The purpose of this study is to develop a neutrosophic multi-criteria group decision-making model based on hybrid scoreaccuracy functions for teacher recruitment in higher education. Eight criteria obtained from expert opinions are considered for recruitment process. The criteria are namely academic performance index, teaching aptitude, subject knowledge, research experience, leadership quality, personality, management capacity, and personal values. In this paper we use the score and accuracy functions and the hybrid score-accuracy functions of single valued neutrosophic numbers (SVNNs and ranking method for SVNNs. Then, multi-criteria group decision-making method with unknown weights for attributes and incompletely known weights for decision makers is used based on the hybrid score-accuracy functions under single valued neutrosophic environments. We use weight model for attributes based on the hybrid score-accuracy functions to derive the weights of decision makers and attributes from the decision matrices represented by the form of SVNNs to decrease the effect of some unreasonable evaluations. Moreover, we use the overall evaluation formulae of the weighted hybrid scoreaccuracy functions for each alternative to rank the alternatives and recruit the most desirable teachers. Finally, an educational problem for teacher selection is

    Full Text Available Increasing research has focused on the built food environment and nutrition-related outcomes, yet what constitutes a food environment and how this environment influences individual behavior still remain unclear. This study assesses whether travel mode and distance to food shopping venues differ among individuals in varying food environments and whether individual- and household-level factors are associated with food shopping patterns. Fifty neighbors who share a traditionally defined food environment (25 in an unfavorable environment and 25 in a favorable environment were surveyed using a mix of close- and open-ended survey questions. Food shopping patterns were mapped using Geographic Information Systems (GIS. Stores visited were beyond the 0.5-mile (805 meters radius traditionally used to represent the extent of an individual’s food environment in an urban area. We found no significant difference in shopping frequency or motivating factor behind store choice between the groups. No differences existed between the two groups for big food shopping trips. For small trips, individuals in the favorable food environment traveled shorter distances and were more likely to walk than drive. Socioeconomic status, including car ownership, education, and income influenced distance traveled. These findings highlight the complexities involved in the study and measurement of food environments.

    Detailed studies of petrology, palaeocurrent direction, palaeogeomorphology and palaeohydrodynamics have been conducted for the Permian-Triassic Cangfanggou Group in the foredeep of the Bogda Mountains in the southeastern Junggar Basin, Xinjiang. Sedimentary environments and facies of alluvial fans and pebbly braided rivers, sandy braided rivers, meandering rivers, low-sinuosity rivers, swamps and fresh-water lakes are recognized in the group. Climate and tectonics of source areas strongly controlled the evolution of the sedimentary environments and facies in the foredeep. The block faulting in the Bogda Mountains increased the ground slope, which led to a drastic increase in the grain size of the sediments.Humid climate, being beneficial to plant growth, would provide protection of channel banks and at the same time weaken chemical weathering in the source area,thus large amounts of clay materials are available for the formation of clay plugs. As a resuit, stable banks and meandering river belts are formed. Conversely, increasing aridity would strengthen mechanical weathering and reduce the mumber of clay plugs.Besides, plants would diminish gradually and channels would become more mobile. In this casc the decrease of transported clay materials would reduce the stability of the bank and result in a wider and shallower channel. Therefore, humid climate is beneficial to the formation of meandering rivers even if there is strong block faulting in the source areas and the ground slope is very large. As aridity further increases, plants would diminish and vanish at last,the meandering rivers prevalent under humid climate conditions would be transformed to low-sinuosity rivers even if the ground is gentle and the land is tectonically stable. And as the climate became more arid and the source area uplifted intensively to provide more sedimentary materials, low-sinuosity' rivers would be transformed to braided ones quickly, and wedge-like sedimentary bodies of the braided

    We explore trends in galaxy properties with Mpc-scale structures using catalogues of environment and large scale structure from the Galaxy And Mass Assembly (GAMA) survey. Existing GAMA catalogues of large scale structure, group and pair membership allow us to construct galaxy stellar mass functions for different environmental types. To avoid simply extracting the known underlying correlations between galaxy properties and stellar mass, we create a mass matched sample of galaxies with stellar masses between $9.5 \\leq \\log{M_*/h^{-2} M_{\\odot}} \\leq 11$ for each environmental population. Using these samples, we show that mass normalised galaxies in different large scale environments have similar energy outputs, $u-r$ colours, luminosities, and morphologies. Extending our analysis to group and pair environments, we show galaxies that are not in groups or pairs exhibit similar characteristics to each other regardless of broader environment. For our mass controlled sample, we fail to see a strong dependence of S\\...

    Homogeneous and heterogeneous iron hydroxide nanoparticle nucleation can occur continuously in both natural and complex aqueous systems. Iron oxide nanoparticles can act as sinks and/or carriers for heavy metal contaminants; therefore, it is important to develop a better understanding of factors affecting their formation. Organic coatings are ubiquitous in aqueous environments where they can exist on mineral surfaces (e.g., biofilm), as nanoparticle surface coatings (e.g., natural organic matter), or be introduced as coagulants in water treatment systems. These surface coatings could influence the formation of iron oxide nanoparticles and thus, the mobility of aqueous contaminants. Therefore, to better understand the fate and transport of contaminants in complex aqueous environments, we need more accurate information about mechanisms governing heterogeneous and homogeneous nucleation and growth of iron(III) hydroxide nanoparticles in the presence of organic surface coatings. In this work, we used a unique measurement technique allowing for simultaneous small-angle X-ray scattering (SAXS) and grazing incidence (GISAXS) analysis to monitor nanoparticle nucleation in solution and at substrate surfaces. Clean quartz, and polyaspartate- and alginate-coated substrates were chosen as model substrates to represent mineral coatings, engineered organic coatings and natural organic coatings. Polyaspartate was determined to be the most negatively charged substrate and quartz to be the least negatively charged substrate; however, after 2 h of reaction, the total nanoparticle volume calculations—determined from GISAXS—indicate that precipitation of positively-charged iron(III) hydroxide nanoparticles is 10 times higher on the quartz substrate than on the polyaspartate substrate. This implies that electrostatics do not govern iron(III) hydroxide nucleation. Furthermore, homogeneous nucleation approximately 250 μm above the substrate surface was highest in the presence of the

    Full Text Available Background: Epidemiological information on childhood disability provides the basis for a country to plan, implement and manage the provision of health, educational and social services for these vulnerable children. There is, however, currently no population-based surveillance instrument that is compatible with the International Classification of Functioning, Disability and Health (ICF, internationally comparable, methodologically sound and comprehensively researched, to identify children under 5 years of age who are living with disability in South Africa and internationally. We conducted a descriptive pilot study to investigate the sensitivity and specificity of translated versions of the Ages and Stages Questionnaire Third Edition (ASQ-III and the Washington Group on Disability Statistics/UNICEF module on child functioning (WG/UNICEF module as parent-reported measures. The aim of our study was to identify early childhood disabilities in children aged 24–48 months in a rural area of South Africa, to determine the appropriateness of these instruments for population-based surveillance in similar contexts internationally.Methods: This study was conducted in the Xhariep District of the Free State Province in central South Africa, with 50 carers whose children were registered on the South African Social Security Agency (SASSA database as recipients of a grant for one of the following: Care Dependency, Child Support or Foster Care. The researchers, assisted by community healthcare workers and SASSA staff members, conducted structured interviews using forward–backward translated versions of the ASQ-III and the WG/UNICEF module.Results: Both measurement instruments had a clinically meaningful sensitivity of 60.0%, high specificity of 95.6% for the ASQ-III and 84.4% for the WG/UNICEF module, and the two instruments agreed moderately (Kappa = 0.6.Conclusion: Since the WG/UNICEF module is quicker to administer, easier to understand

    Screening, diagnosis and assessment of the management of male and female sexual dysfunctions have been greatly improved by the scientific development of self-administered questionnaires. Their use became the rule in clinical trials and epidemiological surveys. Nevertheless, their routine use has not yet become part of daily urological practice. Even if these tools replace neither the patient interview and medical history and the psychological and social context of the sexual behavior, nor clinical examination, they are of great assistance for determining management and are also highly reliable. Medical literature was reviewed and combined with expert opinion of the author. We present here several questionnaires which have been validated in their French version with the methodology for the calculation of the scores. The International Index of Erectile Function (15 items) and two abbreviated versions, the Erectile Function domain (six items) and the Sexual Health Inventory for Men (five questions) are mainly of use for patients with erectile dysfunction. They provide a robust classification of the severity of the condition. The Premature Ejaculation Profile (four questions) is used for patients with premature ejaculation. It describes premature ejaculation with the following criteria: time to ejaculation, control over ejaculation, the level of distress. The Male Health Sexual Questionnaire (25 questions) provides with a wider and more comprehensive approach to male sexuality of male sexuality including: erection, ejaculation, desire and satisfaction. This questionnaire is particularly useful to investigate ejaculatory disorders. Lastly, the Female Sexual Function Index (19 questions) is the tool of choice for female sexuality with questions regarding desire, arousal, lubrication, orgasm, satisfaction and pain. Validated, user-friendly questionnaires are available in French language for the diagnosis and the follow-up of sexual dysfunctions in both men and women

    Questionnaires evaluating hand and wrist function are a very useful tool allowing for objective and systematic recording of symptoms reported by the patients. Most questionnaires generally accepted in clinical practice are available in English and need to be appropriately adapted in translation and undergo subsequent validation before they can be used in another culture and language. The process of translation of the questionnaires was based on the generally accepted guidelines of the International Quality of Life Assessment Project (IQOLA). First, the questionnaires were translated from English into Polish by two independent translators. Then, a joint version of the translation was prepared collectively and translated back into English. Each stage was followed by a written report. The translated questionnaires were then evaluated by a group of patients. We selected 31 patients with wrist problems and asked them to complete the PRWE, Mayo, Michigan and DASH questionnaires twice at intervals of 3-10 days. The results were submitted for statistical analysis. We found a statistically significant (pquestionnaires. A comparison of the PRWE and Mayo questionnaires with the DASH questionnaire also showed a statistically significant correlation (pquestionnaires was successful and that the questionnaires may be used in clinical practice.

    Developmental conditions can strongly influence adult phenotypes and social interactions, which in turn affect key evolutionary processes such as sexual selection and sexual conflict. While the implications of social interactions in phenotypically mixed populations at the individual level are increasingly well known, how these effects influence the fate of groups remains poorly understood, which limits our understanding of the broader ecological implications. To address this problem we manipulated adult phenotypes and social composition in Drosophila melanogaster - by experimentally manipulating the larval density of the group-members - and measured a range of group-level outcomes across the lifespan of groups. Adult groups composed of exclusively low larval-density individuals showed high courtship levels, and low early reproductive rates, group growth rates, offspring mass and offspring eclosion success, relative to high larval-density or mixed larval-density groups. Furthermore, high larval-density groups had lower survival. Offspring mass increased with time, but at a reduced rate in groups when male group members (but not females) were from a mixture of larval-densities; peak reproductive rates were also earlier in these groups. Our results suggest that that variation in developmental conditions experienced by adult group members can modify the reproductive output of groups.

    In this study, we investigate the relationship between academic-preparedness diversity within small learning groups and individual academic performance in science, technology, engineering, and mathematics (STEM) university courses. We further examine whether academic-preparedness diversity impacts academically more- and less-prepared students differently. We use data from 5367 university students nested within 1141 science, engineering, and mathematics learning groups and use a regression analysis to estimate the effect of group diversity, measured in two ways, on course performance. Our results indicate that academic-preparedness diversity is generally associated with positive learning outcomes, that academically less-prepared students derive greater benefit, and that less-prepared students fare best when they are not alone in a group of highly prepared students. Implications for teaching and small-group facilitation are addressed.

  5. Luminosity function of galaxies in groups in the SDSS DR7: the dependence on mass, environment and galaxy type

    CERN Document Server

    2010-01-01

    We perform an analysis of the luminosities of galaxies in groups in the SDSS DR7. We analyse the luminosity function (LF) as a function of group mass for different photometric bands, galaxy populations, galaxy positions within the groups, and the group surrounding large scale density. We find that M* brightens and alpha becomes steeper as a function of mass in all SDSS photometric bands, in agreement with previous results. From the analysis of different galaxy populations, we observe that different methods to split galaxy populations, based on the concentration index or the colour-magnitude diagram, produce quite different behaviours in the luminosity trends, mainly for alpha. These discrepancies and the trends with mass mentioned above are explained when analysing the LF of galaxies classified simultaneously according to their concentrations and colours. We find that only the red spheroids have a LF that strongly depends on group mass. Late type galaxies, whether blue or red, have luminosity functions that d...

    Physical environment influences diet and has been proposed as a determinant of childhood obesity. This cross-sectional study explored physical environment and its associations with diet quality and weight status in a sample of 114 12-year-old children from 4 public schools in the metropolitan area of San Juan, PR. Physical environment was assessed by asking questions regarding the availability and accessibility of healthy and unhealthy foods and food outlets as well as of recreational and sports facilities and equipment. Food intake was determined using a 24-hour diet-recall questionnaire, with the gathered data being used to assess diet quality and calculate the Healthy Eating Index (HEI)-2010. The HEI includes 12 components that are used to determine the compliance of a given diet with federal guidelines. HEI-2010 total score ranges from 0 to 100 and is divided into the following classifications: poor ( 80). Body mass index was computed using measured weight and height and categorized according to the CDC Growth Charts. Thirty-six percent of the participating children were overweight or obese. Nearly 57% had poor diet quality. The lowest HEI-2010 component scores were found for total fruits, whole fruits, total vegetables, whole grains, seafood and plant proteins, and fatty acids. However, diet quality was not associated with weight status or physical environment factors. Compared to the other children in the study, overweight or obese children reported having a significantly (p weight in the children in this sample. However, these same factors did not appear to affect diet quality.

However, only a few studies have investigated the geochemical characteristics of BIFs deposited in a shallow water environment during the Archean, which may have differed from those deposited in a deep water environment. Therefore, we investigated geological, petrographic and geochemical characteristics of ferruginous rocks deposited in a shallow water environment in the Moodies group, in the Barberton Greenstone Belt, South Africa. We obtained ferruginous rock samples in the Moodies group from both an outcrop and underground gold mine, and compared the characteristics of these samples. The 70 sedimentary rock samples were divided into groups based on the dominant Fe minerals they contain: Hematite-rich jaspilite (HM group), Magnetite-rich iron formation/shale/sandstone (MT group), and Siderite-rich sandstone (SD group). Samples in the HM group are predominantly composed of fine-grained quartz (< 20 μm) and hematite (< 5 μm), which are interpreted to be chemical precipitates. Samples in the MT group contain quartz, magnetite, siderite, ankerite, chlorite, biotite and chromite. The grain size of magnetite is much larger (20-150 μm) than that of hematite in the HM group. The magnetite is interpreted as a secondary mineral transformed from hematite during early diagenesis. Results of in situ oxygen isotope analysis by

    In the framework of ISAAC-International Studies on Asthma and Allergies in Childhood--the SIDRIA collaborative project--Studi Italiani sui Disturbi Respiratori nell'Infanzia e l'Ambiente--was established in order to estimate the prevalence of asthma, rinithis and eczema in ten geographic areas in Italy. Data collection spanned from October 1994 to March 1995. Overall 18,737 children 6-7 years old in the primary schools and 21,846 adolescents 13-14 years old in the secondary schools entered the study. The parents of pupils in both age groups filled in standardised questionnaires at home; furthermore both a traditional and a video questionnaire was administered at school to the adolescents. The overall response rate was 96.3%. Based on the interviews to the parents a prevalence of asthma of 9.0% in both age groups was estimated, with the lowest values in Cremona (4.6% children; 6.2% adolescents) and the highest in Roma (11.1% children; 10.4% adolescents). Parents also reported a higher prevalence of wheezing (7.7%) and dyspnea (5.3%) in the last year among children than among adolescents (4.7% and 3.4% respectively). Through the direct interview of the adolescents higher prevalence of asthma (10.4%), wheezing (10.3%) and dyspnea (7.8%) were estimated. Within a narrow range of variability, the reported prevalence of asthma and asthmatic symptoms in Trento and Cremona were the lowest and those in Roma, Empoli and Siena the highest. Nor an urban-rural neither a north-south gradient was detected. A higher prevalence of the same disorders was observed among females than males in the youngest age group, but this difference was no more evident among the adolescents.

    2015-11-01

    Full Text Available Background: Studies on the association between health and neighborhood ethnic composition yielded inconsistent results, possibly due to methodological limitations. We assessed these associations at different spatial scales and for different measures of ethnic composition. Methods: We obtained health survey data of 4673 respondents of Dutch, Surinamese, Moroccan, Turkish other non-Western and other Western origin. Neighborhood ethnic composition was measured for buffers varying from 50–1000 m. Associations with self-rated health were measured using logistic multilevel regression analysis, with control for socioeconomic position at the individual and area level. Results: Overall ethnic heterogeneity was not related to health for any ethnic group. The presence of other Surinamese was associated with poor self-rated health among Surinamese respondents. The presence of Moroccans or Turks was associated with poor health among some groups. The presence of Dutch was associated with better self-rated health among Surinamese and Turks. In most cases, these associations were stronger at lower spatial scales. We found no other associations. Conclusions: In Amsterdam, self-rated health was not associated with ethnic heterogeneity in general, but may be related to the presence of specific ethnic groups. Policies regarding social and ethnic mixing should pay special attention to the co-residence of groups with problematic interrelations.

    The initiative to promote Equal Opportunities at CERN started in 1993. The first Equal Opportunities Officer was appointed in 1996 followed by the creation of the Equal Opportunities Advisory Panel in 1998. Initially the concern was mainly the fair treatment of women in the work-place.

    Microbiological analyses were conducted on wild eels from the L'Albufera Lake (Spain). A total of 174 individuals were collected in two surveys (i.e. year 2008 and autumn-winter 2014) among those caught by local fishermen into the lagoon. The prevalence of Shewanella putrefaciens group was 1.7% in 2008 and rose above 32% in 2014. It was due to an outbreak of shewanellosis that presented a morbidity rate of 64%. S. putrefaciens group strains were isolated as pure cultures from the sick eels that showed white ulcers surrounded by a reddish inflammation, damage of the mouth, extensive skin discoloration, exophthalmia, ascites and bad odour. The S. putrefaciens group was recovered from freshwater samples taken at the L'Albufera system, along autumn-winter 2015. Its counts significantly increased in freshwater parallel to hypoxia and temperature rising. Shewanellae strains were identified as S. putrefaciens and S. xiamenensis by 16S rRNA gene sequencing. These isolates recovered from sick eels or freshwater were virulent for European eel by IP challenge (LD50 10(6)  CFU g(-1) body weight). They also caused 30-38% cumulative mortality, in European eels challenged by a 2-h bath (10(7)  CFU mL(-1) ). These results suggest that shewanellosis could be transmitted through water highlighting the fact that hypoxic conditions increase this bacterium levels in water. © 2016 John Wiley & Sons Ltd.

    Over the past few years, an increase in digitalization of radiology departments can be seen, which has a large impact on the work of the radiologists. This impact is not only demonstrated by the increased use of digital images but also by changing demands on the whole reading environment. In this study, we evaluated the satisfaction of our radiologists with our digital Picture Archival and Communication System environment and their workspace. This evaluation was performed by distribution of a questionnaire consisting of a score sheet and some open questions to all radiologists and residents. Out of 25 questionnaires, 12 were adequately answered and returned. Results clearly showed that most problems were present in the area of reading room design and layout and comfort and ergonomics. Based on the results from this study, adaptations were made and the results were also used in the planning of the redesign of the entire department of radiology.

    2011-01-01

    We present the results of a combined X-ray and Halpha study of 10 galaxy groups and 17 galaxy clusters using the Chandra X-ray Observatory and the Maryland Magellan Tunable Filter. We find no difference in the morphology or detection frequency of Halpha filaments in groups versus clusters, over the mass range 10^13 < M_500 < 10^15 Msun. The detection frequency of Halpha emission is shown to be only weakly dependent on the total mass of the system, at the 52% confidence level. In contrast, we find that the presence of Halpha filaments is strongly correlated with both the global (89% confidence level) and core (84%) ICM entropy, as well as the X-ray cooling rate (72%). The Halpha filaments are therefore an excellent proxy for the cooling ICM. The Halpha filaments are more strongly correlated with the cooling properties of the ICM than with the radio properties of the BCG; this further supports the scenario where these filaments are directly associated with a thermally-unstable, rapidly cooling ICM, rather...

  9. Effects of Random Environment on a Self-Organized Critical System: Renormalization Group Analysis of a Continuous Model

    2016-01-01

    Full Text Available We study effects of the random fluid motion on a system in a self-organized critical state. The latter is described by the continuous stochastic model proposed by Hwa and Kardar [Phys. Rev. Lett. 62: 1813 (1989]. The advecting velocity field is Gaussian, not correlated in time, with the pair correlation function of the form ∝ δ(t − t′/k⊥d-1+ξ , where k⊥ = |k⊥| and k⊥ is the component of the wave vector, perpendicular to a certain preferred direction – the d-dimensional generalization of the ensemble introduced by Avellaneda and Majda [Commun. Math. Phys. 131: 381 (1990]. Using the field theoretic renormalization group we show that, depending on the relation between the exponent ξ and the spatial dimension d, the system reveals different types of large-scale, long-time scaling behaviour, associated with the three possible fixed points of the renormalization group equations. They correspond to ordinary diffusion, to passively advected scalar field (the nonlinearity of the Hwa–Kardar model is irrelevant and to the “pure” Hwa–Kardar model (the advection is irrelevant. For the special case ξ = 2(4 − d/3 both the nonlinearity and the advection are important. The corresponding critical exponents are found exactly for all these cases.

  13. Adult male mice emit context-specific ultrasonic vocalizations that are modulated by prior isolation or group rearing environment.

    Directory of Open Access Journals (Sweden)

    Jonathan Chabout

    Full Text Available Social interactions in mice are frequently analysed in genetically modified strains in order to get insight of disorders affecting social interactions such as autism spectrum disorders. Different types of social interactions have been described, mostly between females and pups, and between adult males and females. However, we recently showed that social interactions between adult males could also encompass cognitive and motivational features. During social interactions, rodents emit ultrasonic vocalizations (USVs, but it remains unknown if call types are differently used depending of the context and if they are correlated with motivational state. Here, we recorded the calls of adult C57BL/6J male mice in various behavioral conditions, such as social interaction, novelty exploration and restraint stress. We introduced a modulator for the motivational state by comparing males maintained in isolation and males maintained in groups before the experiments. Male mice uttered USVs in all social and non-social situations, and even in a stressful restraint context. They nevertheless emitted the most important number of calls with the largest diversity of call types in social interactions, particularly when showing a high motivation for social contact. For mice maintained in social isolation, the number of calls recorded was positively correlated with the duration of social contacts, and most calls were uttered during contacts between the two mice. This correlation was not observed in mice maintained in groups. These results open the way for a deeper understanding and characterization of acoustic signals associated with social interactions. They can also help evaluating the role of motivational states in the emission of acoustic signals.

    Little research has been undertaken into occupational health and safety in the Prosthetics and Orthotics profession. To identify physical, psychosocial and environmental workplace experiences of Prosthetists and Orthotists in organisational settings. Qualitative methodology, cross-sectional design, using thematically analysed data collected from focus groups. Focus groups explored workplace and work experiences across varied Prosthetic and Orthotic settings. Data were thematically analysed to identify physical, psychosocial and environmental workplace experiences. Three major themes, Demands of Work Practice, Impacts on the Individual and Job Design, were identified as problematic. A latent theme Perceptions of Others of P&O highlighted a lack of understanding of the Prosthetics and Orthotics job role outside the profession. This first study of occupational health and safety in the Prosthetics and Orthotics profession identifies a number of important physical and psychosocial issues, including characteristics that have been previously identified as risk factors for work-related musculoskeletal disorders. Findings from the study indicate that some Australian organisations lack understanding of the Prosthetics and Orthotics job role, which results in inappropriate expectations of Prosthetics and Orthotics professionals. Preventing injuries and retaining experienced Prosthetists and Orthotists in the workplace is vital for the profession, and as a result, issues raised in this study require further exploration and then development of appropriate management strategies. This is the first study characterising the experiences of work and risk of injuries in Prosthetists and Orthotists. Preventing injuries and retaining experienced Prosthetists and Orthotists in the workplace is vital for the international profession. Issues raised in this study require further exploration and then development of appropriate management strategies. © The International Society for

    To estimate the prevalence of smoking among Brazilian youth, examining individual, family, and social group factors associated with this habit. Data from youth aged 15 to 24 years living in 17 Brazilian state capitals and the Federal District, obtained from the Household Survey on Risk Factors for Chronic Diseases and Reported Morbidity carried out in 2002 and 2003 by the National Cancer Institute was analyzed. Individual variables (sex, age, schooling, alcohol consumption, self-rated health, physical activity, current school attendance), family variables (age and education of head of household and father, mother, or sibling smoking), and social group variables (best friend smoking, most friends smoking, boyfriend/girlfriend smoking) were analyzed. Generalized estimating equations (GEE) approach to evaluate the factors associated with smoking were used. Considering the effect of the sampling design, smoking prevalence was 12.8%, ranging from 6.8% in Aracaju to 24.1% in Porto Alegre. The following factors were predictors of smoking: male sex, older age, less schooling, not attending school at the time of the survey, poorer health perception, and alcohol consumption. Peer smoking (friends or boyfriend/girlfriend) and smoking among family members (father/mother or sibling) were associated with smoking. There was an effect of parental birth cohort on smoking, with a higher prevalence of smoking among youth whose parents were born in the 1930s. Individual characteristics and the influence of peers and family were relevant for smoking by the youth. Increasing the dialogue among teenagers, school, schoolmates, friends, and parents could lead to a reduction of substance use among youth.

    There is no widely accepted objective evaluation for lumbar spine disorders. New outcome measures should be patient-oriented and should measure symptoms and self-reported functional status in multiple dimensions. The aim of this study was to identify items to be included in the disease-specific quality of life (QOL) questionnaire for the assessments of patients with lumbar spine disorders. The draft of the QOL questionnaire that consisted of a total of 60 items, including 24 items derived from the Japanese version of the Roland Morris Disability Questionnaire (RDQ) and 36 items derived from the Japanese version of Short Form 36 (SF-36), were administered to patients and controls. After obtaining written informed consent, the following data were collected from the patient group (n = 328) and the control group (n = 213): (1) background characteristics, including age, diagnosis, Japanese Orthopaedic Association (JOA) score, and finger to floor distance; (2) responses to the questionnaire; (3) the identification rate by discrimination analysis to select the candidates for adoption and by adopting explanatory variables. The items to be excluded were determined by examining the explanatory variables, which were selected after the discrimination analysis, by setting the candidate to-be-excluded items as an objective variable. Based on the distribution of the responses, two items, RDQ-15 and RDQ-19, were excluded. From the results of the correlation coefficient calculation for each question in the patient group, 33 items were excluded and 27 candidate items were adopted. Based on the adoption explanatory variable used in the discrimination analysis, 25 of the 27 candidate items for adoption were accepted. This study identified the 25 specific questionnaire items that should be included in the questionnaire to evaluate QOL of patients with various lumbar spine disorders.

    We present the final data release from the GALEX Arecibo SDSS Survey (GASS), a large Arecibo program that measured the HI properties for an unbiased sample of ~800 galaxies with stellar masses greater than 10^10 Msun and redshifts 0.025environment is characterized in terms of dark matter halo mass, obtained by cross-matching our sample with the SDSS group catalog of Yang et al. Our analysis provides, for the first time, clear statistical evidence that massive galaxies located in halos with masses of 10^13-10^14 Msun have at least 0.4 dex less HI than objects in lower density environments. The process responsible for the suppression of gas in group galaxies most likely drives the observed quenching of the star formation in these systems. Our findings strongly support the importance of the group env...

  18. Paper to Electronic Questionnaires: Effects on Structured Questionnaire Forms

    Trujillo, Anna C.

    2009-01-01

    With the use of computers, paper questionnaires are being replaced by electronic questionnaires. The formats of traditional paper questionnaires have been found to effect a subject's rating. Consequently, the transition from paper to electronic format can subtly change results. The research presented begins to determine how electronic questionnaire formats change subjective ratings. For formats where subjects used a flow chart to arrive at their rating, starting at the worst and middle ratings of the flow charts were the most accurate but subjects took slightly more time to arrive at their answers. Except for the electronic paper format, starting at the worst rating was the most preferred. The paper and electronic paper versions had the worst accuracy. Therefore, for flowchart type of questionnaires, flowcharts should start at the worst rating and work their way up to better ratings.

    Photosynthetic green sulfur bacteria inhabit anaerobic environments with very low-light conditions. To adapt to such environments, these bacteria have evolved efficient light-harvesting antenna complexes called as chlorosomes, which comprise self-aggregated bacteriochlorophyll c in the model green sulfur, bacterium Chlorobaculum tepidum. The pigment possess a hydroxy group at the C3(1) position that produces a chiral center with R- or S-stereochemistry and the C3(1) -hydroxy group serves as a connecting moiety for the self-aggregation. Chlorobaculum tepidum carries the two possible homologous genes for C3-vinyl hydratase, bchF and bchV. In the present study, we constructed deletion mutants of each of these genes. Pigment analyses of the bchF-inactivated mutant, which still has BchV as a sole hydratase, showed higher ratios of S-epimeric bacteriochlorophyll c than the wild-type strain. The heightened prevalence of S-stereoisomers in the mutant was more remarkable at lower light intensities and caused a red shift of the chlorosomal Qy absorption band leading to advantages for light-energy transfer. In contrast, the bchV-mutant possessing only BchF showed a significant decrease of the S-epimers and accumulations of C3-vinyl BChl c species. As trans- criptional level of bchV was upregulated at lower light intensity, the Chlorobaculum tepidum adapted to low-light environments by control of the bchV transcription. © 2015 The Authors.

  1. Edaphic and arboricolous oribatid mites (Acari; Oribatida in tropical environments: changes in the distribution of higher level taxonomic groups in the communities of species

    Directory of Open Access Journals (Sweden)

    E. Franklin

    Full Text Available We analysed the community of oribatid mites in 25 environments of northern Brazil and one in a rain forest in Peru, encompassing fauna sampled on natural and artificial (nylon-mesh bags substrata, from primary and secondary forests, caatinga, savannahs, flooded forests, bark and epiphytes of trees, and polyculture. A hundred and forty six species are definitively identified from a total of 444 taxa. To determine changes in the community, we took as a basis of comparison the species dominance of Lower Oribatida vs. Oppioidea and Lower Oribatida vs. Poronota. Even considering the different periods in which the inventories were realized and the different sampling methodology compared, the partition of the species of Oribatid mite in larger groups shows tendencies indicating partition of species dominance among the environments studied, showing that they differed in their suitability as habitats for the Oribatid mite community, mainly in respect to the Lower Oribatida, Oppioidea and Poronota composition. These tendencies should be explored in more detail as more becomes known about the species composition in each environment.

    Reef-associated beachrocks from Rameswaram and Keelakkarai group of islands (Holocene)were studied to assess the depositional environment and faunal assemblages. The samples were collected from marine terraces and reef platforms. Granulometrically, they are coarse to medium grained, moderately to very well sorted and fine to very fine skewed in character. The fineskewed nature of the sediments suggests the prevalence of the environmental condition of low energy. The microfaunas associated in beachrock reflect the reefal environment of deposition. Bivariant plots show that the sediments were predominantly deposited under beach environment.The C-M pattern indicates that the sediments are deposited by rolling and graded suspension. The Visher diagram of the study area samples clearly shows the presence of a dominant single saltation, lack of population and no surface creep population. The low diversity and fair preservation of faunas reflect the transgressive phase and the shallow marine environmental condition. The commonly preserved species such as Quinqueloculina sp. and Triloculina sp. indicate the low-energy environmental conditions.

    Evidence suggests that many contemporary urban environments do not support healthy lifestyle choices and are implicated in the obesity pandemic. Middlesbrough, in the northeast of England is one such environment and a prime target for investigation. To measure physical activity (PA) levels in a sample of 28 adolescents (aged 11 to 14 years) and describe the environmental context of their activity and explore where they are most and least active over a 7-day period, accelerometry and Global Positioning System (GPS) technology were used. Twenty-five of these participants also took part in focus groups about their experiences and perceptions of PA engagement. Findings indicated that all participants were relatively inactive throughout the observed period although bouts of moderate-vigorous physical activity (MVPA) were identified in 4 contexts: school, home, street, and rural/urban green spaces, with MVPA levels highest in the school setting. Providing access to local facilities and services (such as leisure centers) is not in itself sufficient to engage adolescents in MVPA. Factors influencing engagement in MVPA were identified within and across contexts, including 'time' as both a facilitator and barrier, perceptions of 'gendered' PA, and the social influences of peer groups and family members.

    Full Text Available Abstract Background Research on the influence of the physical environment on physical activity is rapidly expanding and different measures of environmental perceptions have been developed, mostly in the US and Australia. The purpose of this paper is to (i provide a literature review of measures of environmental perceptions recently used in European studies and (ii develop a questionnaire for population monitoring purposes in the European countries. Methods This study was done within the framework of the EU-funded project 'Instruments for Assessing Levels of Physical Activity and Fitness (ALPHA', which aims to propose standardised instruments for physical activity and fitness monitoring across Europe. Quantitative studies published from 1990 up to November 2007 were systematically searched in Pubmed, Web of Science, TRIS and Geobase. In addition a survey was conducted among members of the European network for the promotion of Health-Enhancing Physical Activity (HEPA Europe and European members of the International Physical Activity and Environment Network (IPEN to identify published or ongoing studies. Studies were included if they were conducted among European general adult population (18+y and used a questionnaire to assess perceptions of the physical environment. A consensus meeting with an international expert group was organised to discuss the development of a European environmental questionnaire. Results The literature search resulted in 23 European studies, 15 published and 8 unpublished. In these studies, 13 different environmental questionnaires were used. Most of these studies used adapted versions of questionnaires that were developed outside Europe and that focused only on the walkability construct: The Neighborhood Environment Walkability Scale (NEWS, the abbreviated version of the NEWS (ANEWS and the Neighborhood Quality of Life Study (NQLS questionnaire have been most commonly used.

    We quantify the effect of the galaxy group environment (for group masses of 1012.5–1014.0 M ⊙) on the current star formation rate (SFR) of a pure, morphologically selected sample of disk-dominated (i.e., late-type spiral) galaxies with redshift ≤0.13. The sample embraces a full representation of quiescent and star-forming disks with stellar mass M * ≥ 109.5 M ⊙. We focus on the effects on SFR of interactions between grouped galaxies and the putative intrahalo medium (IHM) of their host group dark matter halos, isolating these effects from those induced through galaxy–galaxy interactions, and utilizing a radiation transfer analysis to remove the inclination dependence of derived SFRs. The dependence of SFR on M * is controlled for by measuring offsets Δlog(ψ *) of grouped galaxies about a single power-law relation in specific SFR, {\\psi }* \\propto {M}* -0.45+/- 0.01, exhibited by non-grouped “field” galaxies in the sample. While a small minority of the group satellites are strongly quenched, the group centrals and a large majority of satellites exhibit levels of ψ * statistically indistinguishable from their field counterparts, for all M *, albeit with a higher scatter of 0.44 dex about the field reference relation (versus 0.27 dex for the field). Modeling the distributions in Δlog(ψ *), we find that (i) after infall into groups, disk-dominated galaxies continue to be characterized by a similar rapid cycling of gas into and out of their interstellar medium shown prior to infall, with inflows and outflows of ∼1.5–5 x SFR and ∼1–4 x SFR, respectively; and (ii) the independence of the continuity of these gas flow cycles on M * appears inconsistent with the required fueling being sourced from gas in the circumgalactic medium on scales of ∼100 kpc. Instead, our data favor ongoing fueling of satellites from the IHM of the host group halo on ∼Mpc scales, i.e., from gas not initially associated with the galaxies upon infall. Consequently

    Few questionnaires used in monitoring sun-related behavior have been tested for validity. We established criteria validity of a developed questionnaire for monitoring population sun-related behavior. During May-August 2013, 664 Danes wore a personal electronic UV-dosimeter for one week...... that measured the outdoor time and dose of erythemal UVR exposure. In the following week, they answered a questionnaire on their sun-related behavior in the measurement week. Outdoor time measured by dosimetry correlated strongly with both outdoor time and the developed exposure scale measured....... The weekly sunburn fraction correlated strongly with the number of ambient sun hours (r=0.73, p

    The aim of this work is to develop group-contribution(+) (GC(+)) method (combined group-contribution (GC) method and atom connectivity index (CI) method) based property models to provide reliable estimations of environment-related properties of organic chemicals together with uncertainties of estimated property values. For this purpose, a systematic methodology for property modeling and uncertainty analysis is used. The methodology includes a parameter estimation step to determine parameters of property models and an uncertainty analysis step to establish statistical information about the quality of parameter estimation, such as the parameter covariance, the standard errors in predicted properties, and the confidence intervals. For parameter estimation, large data sets of experimentally measured property values of a wide range of chemicals (hydrocarbons, oxygenated chemicals, nitrogenated chemicals, poly functional chemicals, etc.) taken from the database of the US Environmental Protection Agency (EPA) and from the database of USEtox is used. For property modeling and uncertainty analysis, the Marrero and Gani GC method and atom connectivity index method have been considered. In total, 22 environment-related properties, which include the fathead minnow 96-h LC(50), Daphnia magna 48-h LC(50), oral rat LD(50), aqueous solubility, bioconcentration factor, permissible exposure limit (OSHA-TWA), photochemical oxidation potential, global warming potential, ozone depletion potential, acidification potential, emission to urban air (carcinogenic and noncarcinogenic), emission to continental rural air (carcinogenic and noncarcinogenic), emission to continental fresh water (carcinogenic and noncarcinogenic), emission to continental seawater (carcinogenic and noncarcinogenic), emission to continental natural soil (carcinogenic and noncarcinogenic), and emission to continental agricultural soil (carcinogenic and noncarcinogenic) have been modeled and analyzed.

    We use the Zurich ENvironmental Study (ZENS) database to investigate the dependence of the merger fraction and merging galaxy properties on environment in a sample of ~1300 group galaxies with $M>10^{9.2}$ $M_{\\odot}$ and 0.05$10^{13.5}$ $M_{\\odot}$, indicating a suppression of merger activity in massive groups. The observed dependence on halo mass is almost independent of galaxy mass and merger stage. At galaxy masses >$10^{10.2}$ $M_{\\odot}$, most mergers are `dry' accretions of quenched satellites onto quenched centrals, leading to a strong increase of the merger fraction with decreasing group-centric distance at these mass scales. Both satellite and central galaxies in these high mass mergers do not differ in color and structural properties from a control sample of non-merging galaxies of equal mass and rank. At galaxy masses < $10^{10.2}$ $M_{\\odot}$ -- where we mostly probe satellite-satellite pairs and mergers between star forming systems -- close pairs (projected distance <10-20 kpc) show instea...

    2005-01-01

    The aim of the study is to develop and validate a questionnaire able to evaluate the risk of mobbing at the workplace. A multiple-choice questionnaire has been developed which contains, among the different items, only one revealing a mobbing situation. The questionnaire has been administered to two groups (group A--243 subjects in a mobbing situation and group B--63 subjects without exposure to mobbing) and the differences in the scores obtained have been analysed. The questionnaire has proved to be valid and reliable. The results show that the presence of five mobbing actions is sufficient to define the workplace situation as potentially at risk for mobbing. The study reveals some limits in the selection of the two samples thus needing some adjustment. However, the questionnaire, also in the present form, can be considered a tool able to detect the mobbing situations.

    While the processes of schooling in science are usually measured in the resulting skills and products that students acquire or generate, another way to understand science learning is to explore the interactions and discourse that occur during actual learning activities. To investigate the dynamics of inquiry-based learning of earth science, we have explored the patterns that emerge in several learning environments: when teachers create dialog with other teachers in online ESE courses; when they teach earth science lessons in their classrooms; when they discuss their teaching perspectives in interviews; and when small groups of children engage in learning earth science together. By observing and scoring lesson exchanges, preserving online discussions, and documenting words and interactions in audio or video recordings, we are able to distinguish communication configurations that occur when teachers and children engage in the learning of earth science that would otherwise be invisible.

    From the beginning of 2002, Troyes prefecture has initiated a reflection about the management of a nuclear crisis caused by an accident at the Nogent-sur-Seine nuclear power plant. Five workshops have been created, dealing with the following themes: 'Administrative and economic organization', 'Health risk assessment and the epidemiology', 'Monitoring of environment', 'Movement in the contaminated area' and 'Decontamination of soil and Food chain'. The first results of the 'Decontamination of soil and Food chain' working group, which involves the District Agricultural and Forestry Department, the Farmer's Association, the Institute for Radiological Protection and Nuclear Safety and the Veterinary Division are presented in the poster. The scenario that had been developed for the accident considers the release of 3 radionuclides ({sup 131}I, {sup 134}Cs and {sup 137}Cs) in the environment. The scale of the crisis didn't require the evacuation and the sheltering of the population during the emergency phase. The consequences on the local agricultural products (cereal, beetroot, vine, milk, cow meat...) have been assessed up to 50 km and different strategies of agricultural countermeasures have been studied regarding to the local constraints (soil types, surfaces and quantities concerned) and to the consequences of their implementation (waste types and quantities, costs). Then, decision-making diagrams summed up the technical results and allowed to deepen the global thought. (author)

    We present the stellar population properties of 13 dwarf galaxies residing in poor groups (low-density environment, LDE) observed with VIMOS@VLT. Ages, metallicities, and [alpha/Fe] ratios were derived from the Lick indices Hbeta, Mgb, Fe5270 and Fe5335 through comparison with our simple stellar population (SSP) models accounting for variable [alpha/Fe] ratios. For a fiducial subsample of 10 early-type dwarfs we derive median values and scatters around the medians of 5.7 \\pm 4.4 Gyr, -0.26 \\pm 0.28, and -0.04 \\pm 0.33 for age, log Z/Zsun, and [alpha/Fe], respectively. For a selection of bright early-type galaxies (ETGs) from the Annibali et al.2007 sample residing in comparable environment we derive median values of 9.8 \\pm 4.1 Gyr, 0.06 \\pm 0.16, and 0.18 \\pm 0.13 for the same stellar population parameters. It follows that dwarfs are on average younger, less metal rich, and less enhanced in the alpha-elements than giants, in agreement with the extrapolation to the low mass regime of the scaling relations der...

    Full Text Available The aim of this study was to develop a questionnaire for assessing nutritional knowledge among overweight adults. The questionnaire should reveal knowledge about current dietary recommendations, sources of nutrients, everyday food choices, and conditions related to overweight.The first draft of the nutrition knowledge questionnaire (113 items was based on literature review. To ensure content validity and expert-assessed face validity, an expert panel examined the questionnaire. Thereafter, the questionnaire was tested for user friendliness and ambiguity by five students. The questionnaire was pilot tested in a group of obese adults, similar to the target group. The results were analyzed for item difficulty and internal consistency and comments made by respondents were taken into account. Two student groups, differing in nutritional expertise, answered the questionnaire on two occasions to test construct validity and test–retest reliability. After the retest, a total overview of the questionnaire was made by the expert panel. The final questionnaire consisted of 91 items.The pilot study was conducted in obese adults waiting for a gastric bypass operation (n=33. Construct validity (n=34 and test–retest reliability (n=27 was tested in two student groups: public health nutrition students and construction students.Results from the pilot study showed that internal consistency of the three first sections together was 0.84, measured by Cronbach's α. Test of construct validity showed that public health nutrition students scored significantly better than construction students (p<0.001 for all sections, and test–retest reliability for all sections together was 0.82 (Pearson's r.The knowledge questionnaire had reasonable content-, face-, and construct validities and overall good reliability. The questionnaire can be a useful tool for measuring nutrition knowledge among obese adults.

    We present the stellar population properties of 13 dwarf galaxies residing in poor groups (low-density environment, LDE) observed with VIMOS at VLT. Ages, metallicities, and [α/Fe] ratios were derived within an r < re/2 aperture from the Lick indices Hβ, Mgb, Fe5270, and Fe5335 through comparison with our simple stellar population (SSP) models that account for variable [α/Fe] ratios. For a fiducial subsample of 10 early-type dwarfs, we derived median values and scatters around the medians of 5.7 ± 4.4 Gyr, -0.26 ± 0.28, and -0.04 ± 0.33 for age, log Z/Z⊙, and [α/Fe] , respectively. For a selection of bright early-type galaxies (ETGs) from an earlier sample residing in a comparable environment, we derive median values of 9.8 ± 4.1 Gyr, 0.06 ± 0.16, and 0.18 ± 0.13 for the same stellar population parameters. It follows that dwarfs are on average younger, less metal rich, and less enhanced in the α-elements than giants, in agreement with the extrapolation to the low-mass regime of the scaling relations derived for giant ETGs. From the total (dwarf + giant) sample, we find that age ∝ σ0.39 ± 0.22, Z ∝ σ0.80 ± 0.16, and α/Fe ∝ σ0.42 ± 0.22. We also find correlations with morphology, in the sense that the metallicity and the [α/Fe] ratio increase with the Sersic index n or with the bulge-to-total light fraction B/T. The presence of a strong morphology-[α/Fe] relation appears to contradict the possible evolution along the Hubble sequence from low B/T (low n) to high B/T (high n) galaxies. We also investigate the role played by environment by comparing the properties of our LDE dwarfs with those of Coma red passive dwarfs from the literature. We find possible evidence that LDE dwarfs experienced more prolonged star formations than Coma dwarfs, however larger data samples are needed to draw firmer conclusions.

    Przybyszowski, Marek; Bochenek, Grażyna

    2015-01-01

    The achievement and the maintenance of asthma control is currently considered the main goal of asthma treatment. Recent guidelines recommend regular assessment of asthma control and indicate questionnaires as important tools that can facilitate its evaluation. Questionnaires relate to GINA or NAEPP guidelines. Questionnaires constitute complex numerical or categorical scales and consist of several to over a dozen questions relating to the patient's symptoms of asthma, limitations in daily activities and usage of rescue medications within a period of time. Each questionnaire is characterized by the features that affect its reliability and usefulness. In the following paper we discuss most of the questionnaires which assess asthma control. We focus on the items they include and present the results of studies that prove the effectiveness of individual questionnaires in assessment of asthma control. Attention was drawn to the patient groups to which the questionnaires are addressed. We list the features of the questionnaire which should be considered before choosing a test, so that it satisfies both the doctor's and the patient's needs. The role of questionnaires as the easy-to-use tools is growing steadily. Unfortunately, not all are available in Polish language. Conducting appropriate validation studies may allow to use many of them in Polish conditions.

    The International Agency for Research on Cancer estimates that over half of the new cancer cases and almost two-thirds of the cancer deaths in 2012 occurred in low and middle income countries. To discuss the challenges and opportunities to reducing the burden of cancer worldwide, the Molecular Epidemiology and the Environment and the International Issues in Cancer Special Interest Groups joined forces to hold a session during the 38th Annual Meeting of the American Society of Preventive Oncology (March 2014, Arlington, Virginia). The session highlighted three topics of particular interest to molecular cancer prevention researchers working internationally, specifically: 1) biomarkers in cancer research; 2) environmental exposures and cancer; and 3) molecular pathological epidemiology. A major factor for successful collaboration illuminated during the discussion was the need for strong, committed, and reliable international partners. A key element of establishing such relationships is to thoroughly involve individual international collaborators in the development of the research question; engaged international collaborators are particularly motivated to champion and shepherd the project through all necessary steps, including issues relating to institutional review boards, political sensitivity, laboratory-based assays, and tumor subtyping. Also essential is allotting time for the building, maintaining, and investing in such relationships so that successful international collaborations may take root and bloom. While there are many challenges inherent to international molecular cancer research, the opportunities for furthering the science and prevention of cancer worldwide are great, particularly at this time of increasing cancer incidence and prevalence in low and middle income countries.

    2009-12-01

    Teaching methods that provide an opportunity for individual engagement and focussed feedback are required to create an active learning environment for case-based teaching in large groups. A prospective observational controlled study was conducted to evaluate whether the use of an audience response system (ARS) would promote an active learning environment during case-based discussions in large groups, have an impact on student motivation and improve long-term retention. Group A (N = 83) participated in large group case discussions where student participation was voluntary, while for group B (N = 86) an ARS was used. Data collection methods included student and teacher surveys, student focus group interviews, independent observations and 1-year post-course testing. Results indicated that the use of an ARS provided an active learning environment during case-based discussions in large groups by favouring engagement, observation and critical reflection and by increasing student and teacher motivation. Although final exam results were significantly improved in group B, long-term retention was not significantly different between groups. It was concluded that ARS use significantly improved the learning experience associated with case-based discussions in a large group of undergraduate students.

    :bacteria mass ratio of the composite. EXAFS shows that Cu adsorbs to ferrihydrite as an inner-sphere, (CuO4Hn)n - 6 bidentate edge-sharing complex; and to ferrihydrite composites as an inner-sphere, (CuO5Hn)n - 8 monodentate complex with carboxyl surface functional groups present on the bacterial fraction plus the bidentate edge-sharing complex on the ferrihydrite fraction. Our new results combined with previous work on Cu sorption to bacteria, humic substances and iron (hydr)oxides coated with humics, demonstrate the universal importance of the carboxyl moiety for Cu sorption and mobility in natural environments. Taken together these results show that Cu-carboxyl binding is the predominant mechanism by which Cu interacts with abiotic and biotic organic matter, and provides a ubiquitous control on Cu fate and mobility in natural waters, soils and sediments. Our results indicate that in environments where a significant proportion of iron (hydr)oxides are intimately intermixed with an organic fraction, we must consider Cu sequestration by these composites in addition to pure mineral phases.

    During the past decades, tremendous advances have been made in the possibilities to study the diversity of microbial communities in the environment. The development of methods to study these communities on the basis of 16S rRNA gene sequences analysis was a first step into the molecular analysis of environmental communities and the study of biodiversity in natural habitats. A new dimension in this field was reached with the introduction of functional genes of ecological importance and the establishment of genetic tools to study the diversity of functional microbial groups and their responses to environmental factors. Functional gene approaches are excellent tools to study the diversity of a particular function and to demonstrate changes in the composition of prokaryote communities contributing to this function. The phylogeny of many functional genes largely correlates with that of the 16S rRNA gene, and microbial species may be identified on the basis of functional gene sequences. Functional genes are perfectly suited to link culture-based microbiological work with environmental molecular genetic studies. In this review, the development of functional gene studies in environmental microbiology is highlighted with examples of genes relevant for important ecophysiological functions. Examples are presented for bacterial photosynthesis and two types of anoxygenic phototrophic bacteria, with genes of the Fenna-Matthews-Olson-protein (fmoA) as target for the green sulfur bacteria and of two reaction center proteins (pufLM) for the phototrophic purple bacteria, with genes of adenosine-5′phosphosulfate (APS) reductase (aprA), sulfate thioesterase (soxB) and dissimilatory sulfite reductase (dsrAB) for sulfur oxidizing and sulfate reducing bacteria, with genes of ammonia monooxygenase (amoA) for nitrifying/ammonia-oxidizing bacteria, with genes of particulate nitrate reductase and nitrite reductases (narH/G, nirS, nirK) for denitrifying bacteria and with genes of methane

    Full Text Available Abstract Background Valid measures of physical activity correlates in preschool children are lacking. This study aimed to assess the validity, factor structure and internal consistency of a maternal questionnaire on potential correlates of four-year-old children's physical activity. Methods The questionnaire was designed to measure the following constructs: child personal factors; parental support and self-efficacy for providing support; parental rules and restrictions; maternal attitudes and perceptions; maternal behaviour; barriers to physical activity; and the home and local environments. Two separate studies were conducted. Study I included 24 mothers of four-year-old children who completed the questionnaire then participated in a telephone interview covering similar items to the questionnaire. To assess validity, the agreement between interview and questionnaire responses was assessed using Cohen's kappa and percentage agreement. Study II involved 398 mothers of four-year-old children participating in the Southampton Women's Survey. In this study, principal components analysis was used to explore the factor structure of the questionnaire to aid future analyses with these data. The internal consistency of the factors identified was assessed using Cronbach's alpha. Results Kappa scores showed 30% of items to have moderate agreement or above, 23% to have fair agreement and 47% to have slight or poor agreement. However, 89% of items had fair agreement as assessed by percentage agreement (≥ 66%. Limited variation in responses to variables is likely to have contributed to some of the low kappa values. Six questions had a low kappa and low percentage agreement (defined as poor validity; these included questions from the child personal factors, maternal self-efficacy, rules and restrictions, and local environment domains. The principal components analysis identified eleven factors and found several variables to stand alone. Eight of the composite

    A questionnaire survey of Japanese patients with thrombotic microangiopathy (TMA) was carried out to investigate the frequency, laboratory abnormalities, and outcome in 2004. Out of 185 patients, there were 13 with familial TMA and 172 with acquired TMA. In acquired TMA, there were 66 with Escherichia coli O-157 infection (O-157)-related TMA, 35 with ADAMTS13-related TMA, and 22 with other types of TMA. The frequency of TMA in O-157-related TMA was high in patients from 0- to 15-year-old, and acquired TMA without O-157 was frequently observed in patients ranging from 31 to 65 years of age. In the treatment of acquired TMA, including plasma exchange (PE), steroid, antiplatelet agent, and anticoagulant, PE was carried out in 94.3% of ADAMTS13-related TMA, 77.3% of other TMA, and 7.6% of O-157-related TMA. The efficacy of PE and steroid therapy tended to be higher in ADAMTS13 TMA than in other types of TMA. The complete remission rate is the highest in O-157 TMA. The mortality rate was the lowest for O-157 TMA, and this rate also tended to be lower in ADAMTS13-related TMA than in other types of TMA. However, the determination of ADAMTS13 was not universal in Japan at the time of this questionnaire.

    Full Text Available Due to the poor transport system, remoteness and few channels to access to information from the outside world in most minority-inhabited areas in China, buildings in these areas are well preserved. In particular, dwellings in these places show low-tech and ecological features. Different types and the natural environment of the plateau where Shangri-La lies provide people with a variety of living resources. As living environments vary in different areas, different inhabitation forms have been formed. Tibetan people adjust measures to local conditions and excel at using local materials and appropriate technologies to build houses. In this paper, a case study is made of traditional dwellings in Tibetan-inhabited areas in Shangri-La, to analyze low-tech and ecological strategies for traditional dwellings in Tibetan-inhabited areas in Shangri-La, from three aspects: regional environment measures, building technologies and the spatial order system.

    Acculturation is a multidimensional process involving changes in behaviour and beliefs. Questionnaires developed to measure acculturation are typically designed for specific ethnic populations and adult experiences. This study developed a questionnaire that measures acculturation among ethnically diverse populations of youth that can be included as a module in population surveys. Questionnaires measuring acculturation in youth were identified in the literature. The importance of items from the existing questionnaires was determined using a Delphi process and this informed the development of our questionnaire. The questionnaire was then pilot tested using a sample of 248 Canadians aged 18-25 via an online system. Participants identified as East and South East Asian (27.8%), South Asian (17.7%) and Black (13.7%). The majority were 1st (33.5%) or 2nd generation immigrants (52.0%). After redundant items were eliminated, exploratory factor analysis grouped items into domains, and, for each domain, internal consistency, and convergent validity with immigrant generation then age at immigration estimated. A subset of participants re-completed the questionnaire for reliability estimation. The literature review yielded 117 articles that used 13 questionnaires with a total of 440 questions. The Delphi process reduced these to 32 questions. Pilot testing occurred in 248 Canadians aged 18-25. Following item reduction, 16 questions in three domains remained: dominant culture, heritage language, and heritage culture. All had good internal consistency (Cronbach's alphas > .75). The mean dominant domain score increased with immigrant generation (1st generation: 3.69 (95% CI: 3.49-3.89), 2nd: 4.13 (4.00-4.26), 3rd: 4.40 (4.19-4.61)), and mean heritage language score was higher among those who immigrated after age 12 than before (p = .0001), indicative of convergent validity. This Bicultural Youth Acculturation Questionnaire has demonstrated validity. It can be incorporated into

    The Job Demands-Resources model (JD-R model) was used as the theoretical basis of a tailormade questionnaire to measure the psychosocial work environment and personal resources of recently graduated veterinary professionals. According to the JD-R model, two broad categories of work characteristics that determine employee wellbeing can be distinguished: job demands and job resources. Recently, the JD-R model has been expanded by integrating personal resource measures into the model. Three semistructured group interviews with veterinarians active in different work domains were conducted to identify relevant job demands, job resources and personal resources. These demands and resources were organised in themes (constructs). For measurement purposes, a set of questions ('a priori scale') was selected from the literature for each theme. The full set of a priori scales was included in a questionnaire that was administered to 1760 veterinary professionals. Exploratory factor analysis and reliability analysis were conducted to arrive at the final set of validated scales (final scales). 860 veterinarians (73 per cent females) participated. The final set of scales consisted of seven job demands scales (32 items), nine job resources scales (41 items), and six personal resources scales (26 items) which were considered to represent the most relevant potential predictors of work-related wellbeing in this occupational group. The procedure resulted in a tailormade questionnaire: the Veterinary Job Demands and Resources Questionnaire (Vet-DRQ). The use of valid theory and validated scales enhances opportunities for comparative national and international research.

    The tropical forest regeneration technology research group of Kansai Electric Power Company and Kansai Environment Center has been performing the research and development of tropical forest regeneration technology jointly with Indonesia since fiscal 1992. The group was awarded with the Global Environment Technology Prize from Nihon Keizai Shimbun, Inc. As a result of stringent examination on 97 applications, being two times as many as in usual years, the group received high evaluation on the originality, reality and possibility of proliferation of its research, and impacts given to the societies. Two other groups were also selected. The achievements were reported by the representative of the group in the award commemoration lecture at the global environment economist summit held by the Nikkei press the same day. Conventionally, afforestation done with considerable efforts has often been lost by forest fires and slash-and-burn farming, whereas the present research aims at establishing a comprehensive afforestation technology considering social and economic aspects, and CO2 fixation. As one of the choices of flexible measures as a result of the effect of forests having been recognized in COP3, frameworks for utilizing the mechanisms of joint implementation and clean resource development were introduced. Ever increasing expectations are placed on the achievements of the present research works. (NEDO)

    Choi, Bernard C K; Pak, Anita W P

    2005-01-01

    Bias in questionnaires is an important issue in public health research. To collect the most accurate data from respondents, investigators must understand and be able to prevent or at least minimize bias in the design of their questionnaires. This paper identifies and categorizes 48 types of bias in questionnaires based on a review of the literature and offers an example of each type. The types are categorized according to three main sources of bias: the way a question is designed, the way the questionnaire as a whole is designed, and how the questionnaire is administered. This paper is intended to help investigators in public health understand the mechanism and dynamics of problems in questionnaire design and to provide a checklist for identifying potential bias in a questionnaire before it is administered.

    Full Text Available This study aimed to adapt the Emotional Regulation Questionnaire into Turkish and investigate its validity and reliability. The Turkish version of the Emotion Regulation Questionnaire was administered to 442 university students. Firstly, language equivalence of the Turkish version the Emotional Regulation Questionnaire was investigated and findings indicated that the Turkish translation of the Emotion Regulation Questionnaire is equivalent to the original form. Confirmatory factor analyses successfully revealed the two-factor (reappraisal and suppression structure of the Turkish version the Emotional Regulation Questionnaire. Further, based on the two-factor model, results from multi-group analysis indicated that the Turkish version of the Emotional Regulation Questtionnaire has the property of strict factorial invariance across gender, including equal factor loadings, equal item intercepts, and equal item uniqueness (error variances and covariances. The internal consistencies were .78 for the reappraisal and .73 for the suppression subscales. Test-retest reliabilities were .74 for the reappraisal and .72 for the suppression subscales. Overall, the Turkish version of the Emotional Regulation Questionnaire has adequate psychometric properties and can be used to examine emotion regulation among Turkish university students.

    Content analysis of replies to closed questions in questionnaires can be undertaken to understand remarks that may explain the responses, provide illustrative examples of issues raised in the questionnaire, define new issues or issues of importance that were not covered in the questionnaire and inform the design of new questions in future surveys. To discuss the usefulness of summative content analysis to free text in postal questionnaires. Content analysis provides useful comparative insights between two respondent groups in the case example provided. Five themes emerged: poor understanding of the concept of 'patient lateral transfer work technique' and the direct instrument nursing observation (DINO) instrument's key directions; outcomes of patient transfer; positive responses; manual handling risk; and poor translation into English of DINO. Respondents need an opportunity to clarify their responses to questionnaires using free text, to provide insight into their understanding of the question being asked, understanding of the concept or construct being discussed, and data triangulation through the confirmation of item responses and free-text comments. Responses to questions in a postal questionnaire and the opportunity for free-text commentary by respondents enable the identification of hidden meanings behind tickbox responses to questions.

    In Sweden, leave due to sickness was high during the 1990s. The Swedish Social Insurance Agency was able to decrease sick days in the period between 2000 and 2010 but sick days are rising again in Sweden, mostly due to psychological problems among women and partly due to their work environment. It is important to find methods to identify poor work settings to prevent absenteeism due to sickness. The paper aims to discuss these issues. The authors created a web questionnaire focusing on the organizational setting and its impact on employee wellbeing--reported as mental energy, work-related exhaustion and work satisfaction. The questionnaire measures good and poor work environment factors to help managers improve organizational settings. The questionnaire was validated qualitatively and quantitatively. It is possible to measure individual wellbeing in an organizational context at an early stage. The authors followed a company undergoing organizational change and identified groups at risk of developing illness. Managers uncertain about employee mental status can measure employee wellbeing easily and cost effectively to prevent illness. The authors created a method, statistically evaluated, to proactively identify good and poor work environments to promote healthy co-workers.

    A multicenter study of blood cholesterol screening was performed in several typical environments, such as community sites (shopping malls and a supermarket), health care sites, work sites, a blood bank and a school. Cholesterol was measured with a portable, dry-chemistry analyzer using capillary blood obtained by fingerstick. Data are reported from a total of 13,824 participants, spanning the entire age spectrum. Overall, 25% of screened subjects had blood cholesterol levels above the age-specific cutpoints used in the current study. Although in the aggregate this screening experience very closely approximates the expected level of referrals, the proportion of referred screened subjects differed significantly among the 5 types of screening environments and by gender. Follow-up telephone interviews indicated that 53% of referrals had initiated a physician contact. More than 75% of those who had seen a physician reported that the diagnosis of hypercholesterolemia had been confirmed, and almost 72% had been prescribed a diet. A large proportion of referred screened subjects reported having modified their diet, particularly when recommended to do so by a physician. This study has yielded encouraging evidence that physicians gave referred screened subjects appropriate initial advice for managing hypercholesterolemia. The new technology for blood cholesterol measurement evaluated in the current study has proven to be a feasible and reliable means for measuring blood cholesterol in typical screening settings.

  7. Task Group report to the Assistant Secretary for Environment, Safety and Health on oversight of chemical safety at the Department of Energy. Volume 2, Appendices

    Energy Technology Data Exchange (ETDEWEB)

    1992-11-01

    This report presents the results of a preliminary review of chemical safety within the Department of Energy (DOE). The review was conducted by Chemical Safety Oversight Review (CSOR) Teams composed of Office of Environment, Safety and Health (EH) staff members and contractors. The primary objective of the CSOR was to assess, the safety status of DOE chemical operations and identify any significant deficiencies associated with such operations. Significant was defined as any situation posing unacceptable risk, that is, imminent danger or threat to workers, co-located workers, the general public, or the environment, that requires prompt action by EH or the line organizations. A secondary objective of the CSOR was to gather and analyze technical and programmatic information related to chemical safety to be used in conjunction with the longer-range EH Workplace Chemical Accident Risk Review (WCARR) Program. The WCARR Program is part of the ongoing EH oversight of nonnuclear safety at all DOE facilities. `` The program objective is to analyze DOE and industry chemical safety programs and performance and determine the need for additional or improved safety guidance for DOE. During the period June 6, 1992, through July 31, 1992, EH conducted CSORs at five DOE sites. The sites visited were Los Alamos National Laboratory (LANL), Savannah River Site (SRS), the Y-12 Plant (Y-12), Oak Ridge National Laboratory (ORNL), and Lawrence Livermore National Laboratory (LLNL).

    Dental pain, estimated to affect 12-40% of community-dwelling adults, is a symptom of a wide range of clinical conditions. A population screening instrument is needed to study their prevalence. This project aimed to develop a questionnaire for classifying a sample of dental pain patients into three groups of common dental pain conditions, i.e. Group 1 (Acute periapical periodontitis and Irreversible pulpitis), Group 2 (Reversible pulpitis and Dentine hypersensitivity) and Group 3 (Pericoronitis). Initial items were generated through a literature review, individual unstructured patient interviews and consultation with experts. Items generated were administered to a sample of dental pain patients for self-completion. Responses were subjected to a series of factor and discriminant analyses to identify questions capable of differentiating the sample into three groups, originally categorized by clinical diagnosis, with high classification rates. The selected items were administered to a further sample of dental pain patients to test for its sensitivity and specificity in classifying the sample into three groups against the gold standard of clinical diagnosis. The final 16-item Dental Pain Questionnaire (DePaQ) was capable of correctly classifying 89.7% of dental pain cases initially categorized by clinical diagnoses. The sensitivity of the questionnaire was 0.80-Group z1, 0.85-Group 2 and 0.59-Group 3. Specificity was 0.83-Group A1, 0.89-Group A2 and 0.90-Group 3. The DePaQ, which can easily be administered by non-clinical personnel, may be used to collect epidemiological data on common dental pain conditions, assess dental needs for a specified population, and triage of patients seeking treatment for dental pain.

    We present an in depth study on the evolution of galaxy properties in compact groups over the past 3 Gyr. We are using the largest multi-wavelength sample to-date, comprised 1770 groups (containing 7417 galaxies), in the redshift range of 0.01groups has been substantially reduced (3-10 times). Moreover, their star formation histories as well as their UV-optical and mid-infrared colors are significantly different from those of field and cluster galaxies, indicating that compact group galaxies spend more time transitioning through the green valley. The morphological transformation from late-type spirals into early-type galaxies occurs in the mid-infrared transition zone rather than in the UV-optical green valley. We find evidence of shocks...

    The large number of available physical activity (PA) questionnaires makes it difficult to select the most appropriate questionnaire for a certain purpose. This choice is further hampered by incomplete reporting and unsatisfactory evaluation of the content and measurement properties of the questionnaires. We provide a checklist for appraising the qualitative attributes and measurement properties of PA questionnaires, as a tool for selecting the most appropriate PA questionnaire for a certain target population and purpose. The checklist is called the Quality Assessment of Physical Activity Questionnaire (QAPAQ). This review is one of a group of four reviews in this issue of Sports Medicine on the content and measurement properties of physical activity questionnaires. Part 1 of the checklist can be used to appraise the qualitative attributes of PA questionnaires, i.e. the construct to be measured by the questionnaire, the purpose and target population for which it was developed, the format, interpretability and ease of use. Part 2 of the checklist can be used to appraise the measurement properties of a PA questionnaire, i.e. reliability (parameters of measurement error and reliability coefficients), validity (face and content validity, criterion validity and construct validity) and responsiveness. The QAPAQ can be used to select the most appropriate PA questionnaire for a certain purpose, but it can also be used to design or report a study on measurement properties of PA questionnaires. Using such a checklist will contribute to improving the assessment, reporting and appraisal of the content and measurement properties of PA questionnaires.

    Patients' complaints on limitations in activities of daily living (ADL) and sports are possible signs for various injuries of the knee joint. These complaints can be easily assessed by the patient using a questionnaire with visual analogue scale (VAS) responses. A German translation of the English questionnaire concerning knee complaints [4] has been validated and tested for clinical use. It consists of 28 questions. For the statistical analysis, an overall score (VAS score) of the questionnaire was determined. The validation included an expert evaluation on the content of the questionnaire, a test for the reliability, a comparison with subjective knee scoring systems (Cincinnati score, Lysholm score) and a test on VAS score results in patient groups with various knee injuries (discrimination of patients). For the evaluation of operative treatment results, the responsiveness of the questionnaire was tested in patients undergoing arthroscopic meniscus surgery and anterior cruciate ligament reconstruction. The investigation was conducted prior to the operation, 2, 6, 12 and 24 weeks after surgery for both groups and also 36 weeks after surgery for the cruciate ligament patients. Interviews conducted with knee surgeons (so-called knee experts) revealed that 85% judged the questionnaire as being acceptable for clinical use. The reliability of the VAS score for healthy individuals was r = 0.86. The reliability for patients in a postoperative rehabilitation programme was r = 0.92. By means of the VAS score we were able to assess the extent of limitations in knee function in various patient groups with meniscus lesions, insufficiency ot the anterior and posterior cruciate ligaments and chondromalacia.(ABSTRACT TRUNCATED AT 250 WORDS)

    Using a large sample of field and group galaxies drawn from the Pan-STARRS1 Medium-Deep Survey, we present the specific star formation rate (SSFR) - stellar mass (M*) relation, as well as the quiescent fraction versus M* relation in different environments. We confirm that the fraction of quiescent galaxies is strongly dependent on environment at a fixed stellar mass, but that the amplitude and the slope of the star-forming sequence is similar between the field and groups: in other words, the SSFR-density relation at a fixed stellar mass is primarily driven by the change in the star-forming and quiescent fractions between different environments rather than a global suppression in the star formation rate for the star-forming population. However, when we restrict our sample to the cluster-scale environments ($M>10^{14}M_{solar}$), we find a global reduction in the SSFR of the star forming sequence of $17\\%$ at 4$\\sigma$ confidence as opposed to its field counterpart. After removing the stellar mass dependence of...

  16. Evaluating Multilingual Questionnaires: A Sociolinguistic Perspective

    Full Text Available This study aims to develop an assessment tool to evaluate multilingual questionnaires by categorizing the types of translation issues that can lead to measurement errors in cross-cultural surveys. Based on the results of two multilingual projects that cognitively pretested the 2010 U.S. Census questionnaire in five languages and the American Community Survey questionnaire in two languages, we developed a coding scheme guided by sociolinguistic approaches to language and culture to evaluate translated questionnaires by classifying translation issues. In this paper we discuss how the coding scheme is useful in the evaluation of multilingual questionnaires and how it could be integrated productively into the development of such questionnaires and the early rounds of translation. We also suggest feasible solutions to translation issues, to ensure translation quality and achieve not only semantic but functional equivalence across translations. Keywords: survey translation

    Full Text Available Nowadays, the change and dynamism of organizations are the basic principles; therefore, managers should modify the goals, plans and work procedures so that they can be compatible with the environment condition. The management of HSE is not excepted from this principle. The aim of this study was to evaluate the processes affecting HSE. This study was a cross-sectional and applied study using the review of relevant documentation, interviews and brainstorming with experts, and the reviews of Best Practice to identify the HSE's processes. After checking the HSE activities, the 5 processes of HSE training, managing the risks, events, emergencies and contractors and any changes in the other processes of the organization were also suggested. The results showed that a process approaching the form of an intervention programed can be provided in order to have a better interaction between the HSE activities and organizations processes and workplace health promotion for the HSE activities.

    In France, chronic diseases affect 3 million children. In children with chronic conditions, long-term somatic outcome has been well described, but little is known about the psychosocial aspects of well-being. Our aim was to build a self-administered questionnaire of global well-being in adults who had a chronic disease since or during childhood using a multidimensional and nonspecific approach. The questionnaire was constructed by a multidisciplinary group (epidemiologists, clinicians, sociologist, statistician). Items were built in compliance with reference data from the French general population (national surveys, free access) to allow comparative analysis adjusted for age and sex (and eventually other confounding factors) by indirect standardization (qualitative variables) or Z-scores (quantitative variables). The GEDEPAC-2 includes 108 items exploring 11 domains: education, employment, housing, material security, social links, civic engagement, leisure, environment, physical health/risky behavior, health-related quality of life and sex life. Factual questions and satisfaction scales jointly explore social well-being. Quality of life is analyzed in terms of physical quality of life, mental quality of life, fatigue and burden of treatment by 3 questionnaires validated in French (SF-12; MFI-20; Burden of Treatment Questionnaire). Experience of transition from pediatric to adult healthcare is described in 21 items. Paper and electronic versions were developed. Built in a multidimensional approach to well-being and in line with the available reference data, GEDEPAC-2 will facilitate the implementation of future studies on impact in adulthood of chronic disease in childhood.

    We use the Zurich Environmental Study database to investigate the environmental dependence of the merger fraction Γ and merging galaxy properties in a sample of ∼1300 group galaxies with M > 10{sup 9.2} M {sub ☉} and 0.05 < z < 0.0585. In all galaxy mass bins investigated in our study, we find that Γ decreases by a factor of ∼2-3 in groups with halo masses M {sub HALO} > 10{sup 13.5} M {sub ☉} relative to less massive systems, indicating a suppression of merger activity in large potential wells. In the fiducial case of relaxed groups only, we measure a variation of ΔΓ/Δlog (M {sub HALO}) ∼ –0.07 dex{sup –1}, which is almost independent of galaxy mass and merger stage. At galaxy masses >10{sup 10.2} M {sub ☉}, most mergers are dry accretions of quenched satellites onto quenched centrals, leading to a strong increase of Γ with decreasing group-centric distance at these mass scales. Both satellite and central galaxies in these high-mass mergers do not differ in color and structural properties from a control sample of nonmerging galaxies of equal mass and rank. At galaxy masses of <10{sup 10.2} M {sub ☉} where we mostly probe satellite-satellite pairs and mergers between star-forming systems close pairs (projected distance <10-20 kpc) show instead ∼2 × enhanced (specific) star formation rates and ∼1.5 × larger sizes than similar mass, nonmerging satellites. The increase in both size and star formation rate leads to similar surface star formation densities in the merging and control-sample satellite populations.

    designs. To verify the variability interference of the estimates of values used to determinate the plot size with different numbers of plants and groupings of crops, a two-experiment work was carried out. The first trial was carried with zucchini in winter/spring of 2004 and the second in the summer/autumn of 2005. The plants were cultivated in plastic tunnel, with drip irrigation with three lines with 24 plants per row, spacing among plants 0.8m and among lines 1.2m. Each plant was considered as a basic unit (UB of the plot size. The sequence of two, three and four plants in the crop row formed the plots of two, three and four UB of size (X. Analyses were accomplished considering only considered individual and combined harvests. In both experiments, the estimative of variance, variation coefficient and relative information index were obtained. Bartlett's test was applied among the variances of the individual and combined harvests in each size of simulated plot. There were some increases in the estimative in the variance of fruits biomass with the increase of the plot size and/or the number of grouped harvests. The variances, among the grouped harvests, were homogeneous, considering the grouping of three harvests. The relative information index and the relative coefficient present values close to 100% with the groupings of crops. The arrangement of four groups of combined harvests, joined with plots of four plants for zucchini reduce the variability among plots.

    The hydrogen-bond (H-bond) donating strengths of a series of 36 hydroxylic H-bond donors (HBDs) with N-methylpyrrolidinone have been measured in CCl4 solution by FTIR spectrometry. These data allow the definition of a H-bond acidity scale named pKAHY covering almost three pK units, corresponding to 16 kJ mol(-1). These results are supplemented by equilibrium constants determined in CH2Cl2 for one-third of the data set to study compounds showing a poor solubility in CCl4. A systematic comparison of these experimental results with theoretical data computed in the gas phase using DFT (density functional theory) calculations has also been carried out. Quantum electrostatic parameters appear to accurately describe the H-bond acidity of the hydroxyl group, whereas partial atomic charges according to the Merz-Singh-Kollman and CHelpG schemes are not suitable for this purpose. A substantial decrease of the H-bond acidity of the OH group is pointed out when the hydroxyl moiety is involved in intramolecular H-bond interactions. In such situations, the interactions are further characterized through AIM and NBO analyses, which respectively allow localizing the corresponding bond critical point and the quantification of a significant charge transfer from the available lone pair to the σ*OH antibonding orbital. Eventually, the H-bond ability of the hydroxyl groups of steroid derivatives and of lateral chains of amino acids are evaluated on the basis of experimental and/or theoretical data.

    We tested the hypotheses that the hostility and anger scales of the Buss and Perry (1992) [Buss, A. H. & Perry, M. (1992). The Aggression Questionnaire. Journal of Personality and Social Psychology, 63, 452-459.] Aggression Questionnaire would predict anger in college students in response to mistreatment. We found low and high hostility groups did not differ in anger at baseline or after completing a task without provocation, but the high hostility group reported greater anger than the low group after the onset of provocation, which required all students to redo completed tasks because some students (confederates) were observed cheating. Hostility also influenced anxiety and depression, but only anger was greater as a result of the provocation in the high than in the low hostility group. The anger scale did not predict anger in response to provocation, but anger was higher in the high than the low anger group before the provocation. These findings support the construct validity of the Aggression Questionnaire hostility scale as a measure of suspicion, resentment and sensitivity to mistreatment.

    The Questionnaire for Lung Transplant Patients was designed to assess symptoms and activity tolerance in lung transplant recipients during their post-transplant evaluations. The initial psychometric evaluation determined that the questionnaire was clinically useful, reliable, and valid. To report the results of further psychometric analyses in a new, expanded sample of lung transplant recipients and to demonstrate the iterative manner by which instruments are refined and tested. Internal consistency, test-retest stability, convergent validity, factorial validity, and group differences attributable to age, gender, and transplant type were determined in a pooled sample of 177 lung transplant recipients. Sensitivity to change over time was measured in a subsample (n = 51) who provided repeated measures data. The Questionnaire for Lung Transplant Patients and its subscales were internally consistent (Kuder Richardson reliability of 0.73-0.95). Test-retest stability was high (intraclass correlations >0.70). Symptoms showed a significant curvilinear pattern with a tendency to decrease over time before rising again at the 12-month measurement for the total questionnaire (F=6.8, P=.012) and 2 subscales--Respiratory (F=5.6, P=.022) and Activities of Daily Living (F=19.7, PGeneral, and Activities of Daily Living subscales. The Questionnaire for Lung Transplant Patients is a reliable and valid measure for assessing physical symptoms and activity intolerance after lung transplantation in individual recipients, recipients in aggregate, and comparison groups, on one occasion and serially over time. These results will guide future refinement and testing of the Questionnaire for Lung Transplant Patients.

    The purpose of this study is to assess the internal consistency of the subscales of the Hungarian Version of the Codependent Questionnaire (CdQ, Roehling & Gaumond, 1996). Thus, a reliable measurement of codependency for professionals become available in Hungary. The Hungarian Version of the Codependent Questionnaire enables professionals to identify codependent individuals. Our sample (N=137) was recruited from the general population and from self-help groups (82 individuals); and patients with borderline personality disorder (55 individuals) were recruited as clinical control group. The reliability of the questionnaire was assessed by Cronbach's alfa and principal component analysis. In addition, in order to investigate the latent structure, factors analyses and hierarchical cluster analysis were used. Based on our results, the Cronbach's alfa values of the subscales of 'control', 'reliability' and 'intimacy' indicate appropriate reliability, however, the subscale of 'enmeshment' indicates poor reliability. The originally assumed factor structure is not supported by the results of the statistical analyses. The subscales are not separate from each other, which is also indicated by the correlations of the total scores of the subscales. The reliability of the Hungarian Version of the Codependent Questionnaire is nearly identical to the original data, except for one subscale ('enmeshment subscale'). Based on these results the Hungarian Version of the Codependent Questionnaire is considered to be reliable. Besides the Hungarian adaptation, the strength of this study is the investigation of a clinical sample. The use of the questionnaire is recommended without the subscale of 'enmeshment' and further 5 items, and it is suggested to use as one scale.

    Assessing patient satisfaction could be particularly useful in Day Surgery Units, as it helps maintaining and increasing medical care demand. Moreover, it provides feedback that turns out useful for improving quality in departments, and for assessing competence and skill of the whole staff. Background and aim - The purpose of this study was to evaluate the quality perceived in a day surgery unit through a questionnaire, covering the 10 main aspects of the care pathway. The results of a questionnaire filled by patients undergoing Day Surgery between January 2007 and December 2012 were retrospectively reviewed. Patients undergoing surgery between 2007 and 2009 filled up the questionnaire at the time of the discharge, whereas those operated on between 2009 and 2012 filled up the same questionnaire 30 days after discharge. The results were good in terms of number of returned questionnaires, underlining its comprehensibility and suitability to be filled out. The questionnaires' scores were good in both groups, although quality perceived by the group that completed it in 30 days after surgery were lightly better than the other group's. The advantages of the questionnaire consisted of an overall improvement of the quality of care, whereas limitations consisted of the difficulty in setting up the questionnaire accurately, interpreting patients' answers correctly, and dispensing the questionnaire in a timely fashion, in order to evaluate the quality perceived by the patients without any bias related to delay, pain and anxiety.

    Several studies have shown the need to include the physical work environment among the dimensions included in job satisfaction evaluation. However, this dimension was not included in the Font-Roja questionnaire. The present study introduces two items exploring this dimension and adheres to the hypothesis that physical work environment has a significant impact on job satisfaction evaluation. A total of 227 geriatric workers participated in this study. The participants completed the Font-Roja job satisfaction questionnaire with 2 additional items exploring the physical work environment. Factor analysis and principal components analysis with rotation varimax were used to determine the diverse components of job satisfaction. To determine the coherence of the scales and the consistency of the added items, Cronbach's a was used. These methods were applied to both questionnaires, the classical 24-item questionnaire and the extended 26-item questionnaire. The classical Font-Roja questionnaire was composed of 8 factors, explaining 60.02% of the variance. The extended questionnaire was structured into 9 factors, explaining 61.81% of the variance. The new factor was composed of both added items. The internal consistency of the Font-Roja classical scale was alpha = 0.773 and that of the extended scale was alpha = 0.791. The extended scale is superior to the classical scale. The results obtained seem to support the hypothesis that, for analysis of job satisfaction, the instruments used should contain items on the physical work environment.

    Surveys with questionnaires play a vital role in decision and policy making in society. Within medicine, including otolaryngology, surveys with questionnaires may be the only method for gathering data on rare or unusual events. In addition, questionnaires can be developed and validated to be used as outcome measures in clinical trials and other clinical research architecture. Consequently, it is fundamentally important that such tools be properly developed and validated. Just asking questions that have not gone through rigorous design and development may be misleading and unfair at best; at worst, they can result in under- or overtreatment and unnecessary expense. Furthermore, it is important that consumers of the data produced by these instruments understand the principles of questionnaire design to interpret results in an optimal and meaningful way. This article presents a practical guide for understanding the methodologies of survey and questionnaire design, including the concepts of validity and reliability, how surveys are administered and implemented, and, finally, biases and pitfalls of surveys.

    To build and validate an instrument to measure the perceived quality of life in the nutritional status. By focal groups and interviews with nutrition experts, the dimensions with greater affectation were identified. After the judge test, the CaVEN questionnaire was defined. For its valuation a multicentric study was performed, participating 7 Spanish hospitals. The internal structure of the questionnaire was evaluated by explanatory factorial analysis. Reliability was tested using the Cronbach α coefficient and the validity of the criteria with the nutritional Gold Standards. A questionnaire of 26 items with 6 health dimensions was built. It was applied to 68 patients that were valued in the Nutrition Units. The test KMO was 0.756, showing a good accuracy in the Factorial Analysis. The existence of principal dimension of inertia was found (Bartlett p CaVEN (p CaVEN. The CaVEN questionnaire has proved a useful tool for assessing the quality of life related to nutritional status, even in groups with little nutritional alterations.

    To develop and validate a comprehensive, self-administered questionnaire for patients with limited ability to open the mouth, trismus. We derived the Gothenburg Trismus Questionnaire (GTQ) from empirical evidence in the medical literature and interviews with medical experts as well as patients. The draft version was tested in a pilot study (n=18). Patients with a maximal incisal opening (MIO) of ⩽35mm were included. The study comprised patients with benign jaw-related conditions (n=51), patients treated for head and neck (H&N) cancer (n=78) and an age- and gender-matched control group without trismus (n=129). The GTQ instrument was well accepted by the patients, with satisfactory compliance and low rates of missing items. After item reduction, due to items not being conceptually relevant and/or low factor loadings, the GTQ demonstrated high internal consistency (Cronbach's alpha 0.72-0.90), good construct validity and known-group validity. We developed a trismus-specific self-administered questionnaire, the GTQ, that showed good psychometric properties. We suggest this questionnaire, that has clear clinical relevance, to be adopted and used in clinical practice and in research, acting as a screening tool as well as an endpoint in intervention and jaw physiotherapy/rehabilitation studies.

    In the present study, the results of a measurement campaign aiming to assess cancer risk among two special groups of population: policemen and laboratory technicians exposed to the toxic substances, benzene and formaldehyde are presented. The exposure is compared to general population risk. The results show that policemen working outdoor (traffic regulation, patrol on foot or in vehicles, etc.) are exposed at a significantly higher benzene concentration (3-5 times) than the general population, while the exposure to carbonyls is in general lower. The laboratory technicians appear to be highly exposed to formaldehyde while no significant variation of benzene exposure in comparison to the general population is recorded. The assessment revealed that laboratory technicians and policemen run a 20% and 1% higher cancer risk respectively compared to the general population. Indoor working place air quality is more significant in assessing cancer risk in these two categories of professionals, due to the higher Inhalation Unit Risk (IUR) of formaldehyde compared to benzene. Since the origin of the danger to laboratory technicians is clear (use of chemicals necessary for the experiments), in policemen the presence of carbonyls in indoor air concentrations due to smoking or used materials constitute a danger equal to the exposure to traffic originated air pollutants.

    We report deep optical integral-field spectroscopy with the MUSE of the luminous radio-quiet QSO PG1307+085 (z=0.154) obtained during the commissioning of the instrument. Given the high sensitivity and spatial resolution delivered by MUSE, we are able to resolve the compact ($r_e$~1.3") elliptical host galaxy. After careful spectroscopic deblending of the QSO and host galaxy emission, we infer a stellar velocity dispersion of $155\\pm19$km/s. This places PG1307+085 local $M_{BH}-\\sigma_*$ relation within the intrinsic scatter but offset towards a higher black hole mass with respect to the mean relation. The observations with MUSE also reveal a large extended ENLR around PG1307+085 reaching out to 30kpc. In addition, we detect a faint bridge of ionized gas towards the most massive galaxy of the galaxy group being just 20" (50kpc) away. Previous long-slit spectroscopic observations missed most of these extended features due to a miss-aligned slit. The ionized gas kinematics does not show any evidence for gas out...

    Objectives Acculturation is a multidimensional process involving changes in behaviour and beliefs. Questionnaires developed to measure acculturation are typically designed for specific ethnic populations and adult experiences. This study developed a questionnaire that measures acculturation among ethnically diverse populations of youth that can be included as a module in population surveys. Methods Questionnaires measuring acculturation in youth were identified in the literature. The importance of items from the existing questionnaires was determined using a Delphi process and this informed the development of our questionnaire. The questionnaire was then pilot tested using a sample of 248 Canadians aged 18–25 via an online system. Participants identified as East and South East Asian (27.8%), South Asian (17.7%) and Black (13.7%). The majority were 1st (33.5%) or 2nd generation immigrants (52.0%). After redundant items were eliminated, exploratory factor analysis grouped items into domains, and, for each domain, internal consistency, and convergent validity with immigrant generation then age at immigration estimated. A subset of participants re-completed the questionnaire for reliability estimation. Results The literature review yielded 117 articles that used 13 questionnaires with a total of 440 questions. The Delphi process reduced these to 32 questions. Pilot testing occurred in 248 Canadians aged 18–25. Following item reduction, 16 questions in three domains remained: dominant culture, heritage language, and heritage culture. All had good internal consistency (Cronbach’s alphas > .75). The mean dominant domain score increased with immigrant generation (1st generation: 3.69 (95% CI: 3.49–3.89), 2nd: 4.13 (4.00–4.26), 3rd: 4.40 (4.19–4.61)), and mean heritage language score was higher among those who immigrated after age 12 than before (p = .0001), indicative of convergent validity. Conclusions This Bicultural Youth Acculturation Questionnaire has

  3. Is physical activity in natural environments better for mental health than physical activity in other environments?

    Experimental evidence suggests that there may be synergy between the psychological benefits of physical activity, and the restorative effects of contact with a natural environment; physical activity in a natural environment might produce greater mental health benefits than physical activity elsewhere. However, such experiments are typically short-term and, by definition, artificially control the participant types, physical activity and contact with nature. This observational study asked whether such effects can be detected in everyday settings at a population level. It used data from the Scottish Health Survey 2008, describing all environments in which respondents were physically active. Associations were sought between use of each environment, and then use of environments grouped as natural or non-natural, and the risk of poor mental health (measured by the General Health Questionnaire (GHQ)) and level of wellbeing (measured by the Warwick Edinburgh Mental health and Wellbeing Score (WEMWBS). Results showed an independent association between regular use of natural environments and a lower risk of poor mental health, but not for activity in other types of environment. For example, the odds of poor mental health (GHQ ≥ 4) among those regularly using woods or forests for physical activity were 0.557 (95% CI 0.323-0.962), compared to non-users. However, regular use of natural environments was not clearly associated with greater wellbeing, whilst regular use of non-natural environments was. The study concludes that physical activity in natural environments is associated with a reduction in the risk of poor mental health to a greater extent than physical activity in other environments, but also that activity in different types of environment may promote different kinds of positive psychological response. Access to natural environments for physical activity should be protected and promoted as a contribution to protecting and improving population mental health.

  4. The thoracic morphology of the wingless dune cricket Comicus calcaris (Orthoptera: Schizodactylidae): Novel apomorphic characters for the group and adaptations to sand desert environments.

    Schizodactylidae, splay-footed or dune crickets, represents a distinct lineage among the highly diverse orthopteran subgroup Ensifera (crickets, katydids and allies). Only two extant genera belong to the Schizodactylidae: the winged Eurasian genus Schizodactylus, whose ecology and morphology is well documented, and the wingless South African Comicus, for which hardly any studies providing morphological descriptions have been conducted since its taxonomic description in 1888. Based on the first in-depth study of the skeletomuscular system of the thorax of Comicus calcaris Irish 1986, we provide information on some unique characteristics of this character complex in Schizodactylidae. They include a rigid connection of prospinasternite and mesosternum, a T-shaped mesospina, and a fused meso- and metasternum. Although Schizodactylidae is mainly characterized by group-specific anatomical traits of the thorax, its bifurcated profuca supports a closer relationship to the tettigonioid ensiferans, like katydids, wetas, and hump-winged crickets. Some specific features of the thoracic musculature of Comicus seem to be correlated to the skeletal morphology, e.g., due to the rigid connection of the tergites and pleurites in the pterothorax not a single direct flight muscle is developed. We show that many of the thoracic adaptations in these insects are directly related to their psammophilous way of life. These include a characteristic setation of thoracic sclerites that prevent sand grains from intrusion into vulnerable membranous areas, the striking decrease in size of the thoracic spiracles that reduces the respirational water loss, and a general trend towards a fusion of sclerites in the thorax.

  8. Provenance and sedimentary environments of the Proterozoic São Roque Group, SE-Brazil: Contributions from petrography, geochemistry and Sm-Nd isotopic systematics of metasedimentary rocks

    The Proterozoic metasedimentary sequences exposed in the São Roque Domain (Apiaí Terrane, Ribeira Belt, southeast Brazil) consist of metasandstones and meta-felspathic wackes with some volcanic layers of within-plate geochemical signature (Boturuna Formation), a passive margin turbidite sequence of metawackes and metamudstones (Piragibu Formation), and volcano-sedimentary sequences with MORB-like basalts (Serra do Itaberaba Group; Pirapora do Bom Jesus Formation). A combination of zircon provenance studies in metasandstones, whole-rock geochemistry and Sm-Nd isotopic systematics in metamudstones was used to understand the provenance and tectonic significance of these sequences, and their implications to the evolution of the Precambrian crust in the region. Whole-rock geochemistry of metamudstones, dominantly from the Piragibu Formation, points to largely granitic sources (as indicated for instance by LREE-rich moderately fractionated REE patterns and subtle negative Eu anomalies) with some mafic contribution (responding for higher contents of Fe2O3, MgO, V, and Cr) and were subject to moderate weathering (CIA - 51 to 85). Sm-Nd isotope data show three main peaks of Nd TDM ages at ca. 1.9, 2.1 and 2.4 Ga; the younger ages define an upper limit for the deposition of the unit, and reflect greater contributions from sources younger than the >2.1 Ga basement. The coincident age peaks of Nd TDM and U-Pb detrital zircons at 2.1-2.2 Ga and 2.4-2.5 Ga, combined with the possible presence of a small amount of zircons derived from mafic (gabbroid) sources with the same ages, as indicated by a parallel LA-ICPMS U-Pb dating study in metapsammites, are suggestive that these were major periods of crustal growth in the sources involving not only crust recycling but also some juvenile addition. A derivation from similar older Proterozoic sources deposited in a passive margin basin is consistent with the main sedimentary sequences in the São Roque Domain being broadly coeval and

    The present study aimed to develop a Japanese version of the Short-Form McGill Pain Questionnaire (SF-MPQ-J) that focuses on cross-culturally equivalence to the original English version and to test its reliability and validity. Cross-sectional design. In study 1, SF-MPQ was translated and adapted into Japanese. It included construction of response scales equivalent to the original using a variation of the Thurstone method of equal-appearing intervals. A total of 147 undergraduate students and 44 pain patients participated in the development of the Japanese response scales. To measure the equivalence of pain descriptors, 62 pain patients in four diagnostic groups were asked to choose pain descriptors that described their pain. In study 2, chronic pain patients (N=126) completed the SF-MPQ-J, the Long-Form McGill Pain Questionnaire Japanese version (LF-MPQ-J), and the 11-point numerical rating scale of pain intensity. Correlation analysis examined the construct validity of the SF-MPQ-J. The results from study 1 were used to develop SF-MPQ-J, which is linguistically equivalent to the original questionnaire. Response scales from SF-MPQ-J represented the original scale values. All pain descriptors, except one, were used by >33% in at least one of the four diagnostic groups. Study 2 exhibited adequate internal consistency and test-retest reliability, with the construct validity of SF-MPQ-J comparable to the original. These findings suggested that SF-MPQ-J is reliable, valid, and cross-culturally equivalent to the original questionnaire. Researchers might consider using this scale in multicenter, multi-ethnical trials or cross-cultural studies that include Japanese-speaking patients. Wiley Periodicals, Inc.

    To validate the Subjective Global Nutritional Assessment (SGNA) questionnaire for Brazilian children and adolescents. A cross-sectional study with 242 patients, aged 30 days to 13 years, treated in pediatric units of a tertiary hospital with acute illness and minimum hospitalization of 24h. After permission from the authors of the original study, the following criteria were observed to obtain the validation of SGNA instruments: translation and backtranslation, concurrent validity, predictive validity, and inter-observer reliability. The variables studied were age, sex, weight and length at birth, prematurity, and anthropometry (weight, height, body mass index, upper arm circumference, triceps skinfold, and subscapular skinfold). The primary outcome was considered as the need for admission/readmission within 30 days after hospital discharge. Statistical tests used included ANOVA, Kruskal-Wallis, Mann-Whitney, chi-square, and Kappa coefficient. According to SGNA score, 80% of patients were considered as well nourished, 14.5% moderately malnourished, and 5.4% severely malnourished. Concurrent validity showed a weak correlation between the SGNA and anthropometric measurements (p<0.001). Regarding predictive power, the main outcome associated with SGNA was length of admission/readmission. Secondary outcomes associated included the following: length of stay at the unit after SGNA, weight and length at birth, and prematurity (p<0.05). The interobserver reliability showed good agreement among examiners (Kappa=0.74). This study validated the SGNA in this group of hospitalized pediatric patients, ensuring its use in the clinical setting and for research purposes in the Brazilian population.

    To develop a questionnaire to evaluate preferences for attributes of intranasal corticosteroids (INSs) in clinical trials with allergic rhinitis (AR) patients. Established questionnaire development practices were used, including performance of a literature review and use of patient and physician focus groups, cognitive debriefing interviews, and pilot testing before validation. Findings from patient and physician focus groups suggest that sensory attributes are relevant to AR patients when choosing INSs. Physician focus groups identified the need for 2 distinct preference instruments, a clinical trial patient preference questionnaire (CTPPQ) and a clinical practice preference questionnaire (CPPPQ). A pilot study suggests that the CTPPQ is capable of discriminating between 2 INSs in the clinical trial setting. Initial findings suggest that items in the CTPPQ and CPPPQ are easy to understand and relevant to patients. Further validation studies with larger sample sizes are needed to assess the psychometric properties of both questionnaires. B-20.

    Full Text Available Objective: This study aimed to examin the psychometric characteristics of the Persian version of Reproductive Health Assessment Questionnaire for Women of Reproductive Age (RHAQWRA.Materials and methods: This study was a cross sectional study. We selected 150 women aged 18- 45 years based on convenience sampling method who lived in the Quake-hit areas  in eastern part of Iran in 2013. Some previously recognized and established instructions were undertaken in translating and adapting the RHAQWRA questionnaire culturally. We sought help and feedback from teenagers and experts in the fields of midwifery, sociology, and epidemiology to establish the face and content validity of the questionnaire. To examine the test-retest reliability indices of all the items, we used Kappa and McNemar tests.Results: The Content Validity Index (CVI and Content Validity Ratio (CVR scores for RHAQWRA were above 0.70. Results from Kappa and McNemar tests indicated a high degree of test-retest reliability. In order to evaluate the construct validity, known- group comparison (women with and without unwanted pregnancy was used. The internal consistency reliability indexes for the subscales obtained through Cronbach’s alpha were between 0.68 and 0.87.Conclusion: The findings suggest that the Iranian version of RHAQWRA is a valid and reliable questionnaire which can be used for measuring reproductive health needs during disasters.

    There is a considerable discrepancy between the number of identified occupational-related bladder cancer cases and the estimated numbers particularly in emerging nations or less developed countries where suitable approaches are less or even not known. Thus, within a project of the World Health Organisation Collaborating Centres in Occupational Health, a questionnaire of the Dortmund group, applied in different studies, was translated into more than 30 languages (Afrikaans, Arabic, Bengali, Chinese, Czech, Dutch, English, Finnish, French, Georgian, German, Greek, Hindi, Hungarian, Indonesian, Italian, Japanese, Kannada, Kazakh, Kirghiz, Korean, Latvian, Malay, Persian (Farsi), Polish, Portuguese, Portuguese/Brazilian, Romanian, Russian, Serbo-Croatian, Slovak, Spanish, Spanish/Mexican, Tamil, Telugu, Thai, Turkish, Urdu, Vietnamese). The bipartite questionnaire asks for relevant medical information in the physician's part and for the occupational history since leaving school in the patient's part. Furthermore, this questionnaire is asking for intensity and frequency of certain occupational and non-occupational risk factors. The literature regarding occupations like painter, hairdresser or miner and exposures like carcinogenic aromatic amines, azo dyes, or combustion products is highlighted. The questionnaire is available on www.ifado.de/BladderCancerDoc.

    Full Text Available Abstract Background The administrative and professional consequences of access targets for general practices, as detailed in the new GMS contract, are unknown. This study researched the effect of implementing the access targets of the new GP contract on general practice appointment systems, and practice manager satisfaction in a UK primary health care setting. Methods A four-part postal questionnaire was administered. The questionnaire was modified from previously validated questionnaires and the findings compared with data obtained from the Western Health and Social Services Board (WHSSB in N Ireland. Practice managers from the 59 general practices in the WHSSB responded to the questionnaire. Results There was a 94.9% response rate. Practice managers were generally satisfied with the introduction of access targets for patients. Some 57.1% of responding practices, most in deprived areas (Odds ratio 3.13 -95% CI 1.01 – 9.80, p = 0.0256 had modified their appointment systems. Less booking flexibility was reported among group practices (p = 0.006, urban practices (p Conclusion The findings demonstrated the ability of general practices within the WHSSB to adjust to a demanding component of the new GP contract. Issues relating to the flexibility of patient appointment booking systems, receptionists' training and the development of the primary care nursing role were highlighted by the study.

    To trace how dust-obscured star formation varies with environment, we compare the fraction of 24 micron sources in a super galaxy group to the field and a rich galaxy cluster at z~0.35. We draw on multi-wavelength observations that combine Hubble, Chandra, and Spitzer imaging with extensive optical spectroscopy (>1800 redshifts) to isolate galaxies in each environment and thus ensure a uniform analysis. We focus on the four galaxy groups in supergroup 1120-12 that will merge to form a galaxy cluster comparable in mass to Coma. We find that 1) the fraction of supergroup galaxies with SFR(IR)>3 Msun/yr is four times higher than in the cluster (32% vs. 7%); 2) the supergroup's infrared luminosity function confirms that it has a higher density of IR members compared to the cluster and includes bright IR sources not found in galaxy clusters at z0.5 Mpc); once their star formation is quenched, most will evolve into faint red galaxies. Our analysis indicates that the supergroup's 24 micron population also differs fr...

  3. Development and Psychometric Evaluation of the Speaking Up About Patient Safety Questionnaire.

    Speaking up about safety concerns by staff is important to prevent medical errors. Knowledge about healthcare workers' speaking up behaviors and perceived speaking up climate is useful for healthcare organizations (HCOs) to identify areas for improvement. The aim of this study was to develop a short questionnaire allowing HCOs to assess different aspects of speaking up among healthcare staff. Healthcare workers (n = 523) from 2 Swiss hospitals completed a questionnaire covering various aspects of speak up-related behaviors and climate. Psychometric testing included descriptive statistics, correlations, reliabilities (Cronbach α), principal component analysis, and t tests for assessing differences in hierarchical groups. Principal component analysis confirmed the structure of 3 speaking up behavior-related scales, that is, frequency of perceived concerns (concern scale, α = 0.73), withholding voice (silence scale, α = 0.76), and speaking up (speak up scale, α = 0.85). Concerning speak up climate, principal component analysis revealed 3 scales (psychological safety, α = 0.84; encouraging environment, α = 0.74; resignation, α = 0.73). The final survey instrument also included items covering speaking up barriers and a vignette to assess simulated behavior. A higher hierarchical level was mostly associated with a more positive speak up-related behavior and climate. Patient safety concerns, speaking up, and withholding voice were frequently reported. With this questionnaire, we present a tool to systematically assess and evaluate important aspects of speaking up in HCOs. This allows for identifying areas for improvement, and because it is a short survey, to monitor changes in speaking up-for example, before and after an improvement project.

    Postal questionnaires are simple and economical for collecting outcome data for randomised controlled trials (RCTs) but are prone to non-response. In the RECORD trial (a large pragmatic publicly funded RCT in UK) non-responders were sent a reminder and another questionnaire at 1 year, of which 40% were returned. In subsequent years we investigated the effect of an advance telephone call to non-responders on responses rate to reminder questionnaires and the next questionnaire 4 months later. Non-responders to annual questionnaires were randomised to receive a telephone call from the trial office ahead of the reminder questionnaire in addition to the usual reminder schedule (n=390) or to a control group that received the usual reminder schedule only (n=363). The primary outcome was response to the reminder questionnaire within 21 days; secondary outcomes were response to a questionnaire 4 months later; completeness of quality of life instruments; and the number of participants declining further follow-up. Results are presented as odds ratios from a logistic regression intention-to-treat (ITT) analysis and then percentage difference and 95% confidence intervals (CI) for both ITT and average treatment effect on the treated (ATT) analyses. The proportions that responded were 67.8% (265/390) in the intervention group compared to 62.5% (227/363) in the control group. The ITT estimate was a 5.4% increase (95% CI -1.4 to 12.2). Four months later percentages responding were 51.8% (202) and 42.7% (155). The ITT estimate was a 9.1% increase (95% CI 2.0 to 16.2). In the intervention group 12.3% (48/390) of participants were not telephoned because questionnaires were returned before the scheduled telephone call. ATT estimates adjusting for this were 6.2% (95% CI -1.6 to 14.0) and 10.4% (95% CI 2.2 to 18.5), respectively. The telephone call resulted in a slight increase in response to the reminder questionnaire, however at 4 months later the proportion in the telephoned group

    Full Text Available CONTEXT: Validated questionnaires are essential tools to be utilized in epidemiological research. At the moment there are no Rome III diagnostic questionnaires translated to Portuguese. OBJECTIVE: To validate the Portuguese version of the Rome III Diagnostic Questionnaire for Functional Dyspepsia. METHODS: The questionnaire has been translated following the Rome III recommendations. Hundred and nine consecutive patients with functional dyspepsia answered the questionnaire. The control group comprised 100 healthy consecutive blood donors, without digestive problems. Internal consistency, reproducibility, responsiveness, discriminate validity and content analysis were evaluated. RESULTS: Cronbach's α coefficient was 0.92. The questionnaire showed reliability: the patients answered it in a similar way on two distinct occasions and their responses were substantially very similar (P = 1.00. The questionnaire was able to demonstrate changes when they occur (P<0.01. Two "blinded" gastroenterologists agreed that the questionnaire adequately evaluated Functional Dyspepsia. When we compared the answers between patients and controls, the questionnaire showed that 5.3% of controls had Functional Dyspepsia symptoms compared with 91.2% of the patients (P<0.01. CONCLUSION: The Rome III Diagnostic Questionnaire for Functional Dyspepsia is ready to be used in clinical researches in lusophone countries, as it has been successfully validated in Portuguese.

    2015-01-01

    Full Text Available Collaboration between patients and their medical and technical experts enabled the development of an automated questionnaire for the early detection of COPD exacerbations (AQCE. The questionnaire consisted of fourteen questions and was implemented on a computer system for use by patients at home in an un-supervised environment. Psychometric evaluation was conducted after a 6-month field trial. Fifty-two patients were involved in the development of the questionnaire. Reproducibility was studied using 19 patients (ICC = 0.94. Sixteen out of the 19 subjects started the 6 month-field trial with the computer application. Cronbach’s alpha of 0.81 was achieved. In the concurrent validity analysis, a correlation of 0.80 (p = 0.002 with the CCQ was reported. The results suggest that AQCE is a valid and reliable questionnaire, showing that an automated home-based electronic questionnaire may enable early detection of exacerbations of COPD.

    2005-06-01

    To validate a questionnaire for the diagnosis of orhorexia oervosa, an eating disorder defined as "maniacal obsession for healthy food". 525 subjects were enrolled. Then they were randomized into two samples (sample of 404 subjects for the construction of the test for the diagnosis of orthorexia ORTO-15; sample of 121 subjects for the validation of the test). The ORTO-15 questionnaire, validated for the diagnosis of orthorexia, is made-up of 15 multiple-choice items. The test we proposed for the diagnosis of orthorexia (ORTO 15) showed a good predictive capability at a threshold value of 40 (efficacy 73.8%, sensitivity 55.6% and specificity 75.8%) also on verification with a control sample. However, it has a limit in identifying the obsessive disorder. For this reason we maintain that further investigation is necessary and that new questions useful for the evaluation of the obsessive-compulsive behavior should be added to the ORTO-15 questionnaire.

    1999-07-01

    In order to ensure that buildings and HVAC plans are truly for people and actually satisfy the occupants, it is necessary to obtain feedback from the occupants. This can be done by a novel questionnaire that produces a readily understandable fingerprint and score to indicate occupants' liking of their environments. The questionnaire uses a double-Likert section rating the liking and importance of up to 24 environmental, organizational, and human factors. To date it has been used primarily in U.K. offices, including modern deep-plan, naturally ventilated buildings. Comparison is made to previous results from 1,400 occupants in 12 offices that are air conditioned and naturally ventilated, where scores ranged from +17% (greatly liked by the occupants) to {minus}15% (greatly disliked). However, four U.K. offices with 1,300 occupants, which are discussed in detail, produced very low scores, {minus}14% to {minus}39%, the latter for a building with no windows. The fingerprints and scores were supported by an independent consultant's survey of the buildings and plant and also detailed factor analysis. The latter indicated that the 18 factors used in the questionnaire could be reduced to 5 general factors. The most important factors for the occupants for their ideal office were temperature, health, ventilation, and heating control, and the least important were the appearance of the building, distance to a window, humidity, and glare. It is proposed that this questionnaire is a useful management tool and suitable for use as a final commissioning tool.

    Due to its potential impact on women's psychological health, assessing perceptions of their childbirth experience is important. The aim of this study was to develop a multidimensional self-reporting questionnaire to evaluate the childbirth experience. Factors influencing the childbirth experience were identified from a literature review and the results of a previous qualitative study. A total of 25 items were combined from existing instruments or were created de novo. A draft version was pilot tested for face validity with 30 women and submitted for evaluation of its construct validity to 477 primiparous women at one-month post-partum. The recruitment took place in two obstetric clinics from Swiss and French university hospitals. To evaluate the content validity, we compared item responses to general childbirth experience assessments on a numeric, 0 to 10 rating scale. We dichotomized two group assessment scores: "0 to 7" and "8 to 10". We performed an exploratory factor analysis to identify underlying dimensions. In total, 291 women completed the questionnaire (response rate = 61%). The responses to 22 items were statistically significant between the 0 to 7 and 8 to 10 groups for the general childbirth experience assessments. An exploratory factor analysis yielded four sub-scales, which were labelled "relationship with staff" (4 items), "emotional status" (3 items), "first moments with the new born," (3 items) and "feelings at one month postpartum" (3 items). All 4 scales had satisfactory internal consistency levels (alpha coefficients from 0.70 to 0.85). The full 25-item version can be used to analyse each item by itself, and the short 4-dimension version can be scored to summarize the general assessment of the childbirth experience. The Questionnaire for Assessing the Childbirth Experience (QACE) could be useful as a screening instrument to identify women with negative childbirth experiences. It can be used as both a research instrument in its short version

    2014-06-01

    Full Text Available Background: The purpose of this article is to draw attention to a significant role of social approval variable in the qustionnairebased diagnosis of drivers' psychological aptitude. Material and Methods: Three questionnaires were used: Formal Characteristics of Behavior - Temperament Inventory (FCB-TI, Eysenck Personality Questionnaire (EPQ-R(S and Impulsiveness Questionnaire (Impulsiveness, Venturesomeness, Empathy - IVE. Three groups of drivers were analyzed: professional "without crashes" (N = 46, nonprofessional "without crashes" (N = 75, and nonprofessional "with crashes" (N = 75. Results: Nonprofessional drivers "without crashes" significantly stood up against other drivers. Their personality profile, indicating a significantly utmost perseveration, emotional reactivity, neuroticism, impulsiveness and the lowest endurance did not fit in to the requirements to be met by drivers. The driver safety profile was characteristic of professional drivers (the lowest level of perseveration, impulsiveness and neuroticism and the highest level of endurance. Similar profile occurred among nonprofessional drivers - the offenders of road crashes. Compared to the nonprofessional "without crashes" group, professional drivers and offenders of road crashes were also characterized by a significantly higher score on the Lie scale, determining the need for social approval. This is likely to result from the study procedure according to which the result of professional drivers testing had an impact on a possible continuity of their job and that of nonprofessional drivers "with crashes" decided about possible recovery of the driving license. Conclusions: The variable of social approval can be a significant artifact in the study of psychological drivers' testing and reduce the reliability of the results of questionnaire methods.

    Workplace dietary intervention studies in low- and middle-income countries using psychometrically sound measures are scarce. This study aimed to validate a nutrition knowledge questionnaire (NQ) and its utility in evaluating the changes in knowledge among participants of a Nutrition Education Program (NEP) conducted at the workplace. A NQ was tested for construct validity, internal consistency and discriminant validity. It was applied in a NEP conducted at six workplaces, in order to evaluate the effect of an interactive or a lecture-based education programme on nutrition knowledge. Four knowledge domains comprising twenty-three items were extracted in the final version of the NQ. Internal consistency of each domain was significant, with Kuder-Richardson formula values>0·60. These four domains presented a good fit in the confirmatory factor analysis. In the discriminant validity test, both the Expert and Lay groups scored>0·52, but the Expert group scores were significantly higher than those of the Lay group in all domains. When the NQ was applied in the NEP, the overall questionnaire scores increased significantly because of the NEP intervention, in both groups (Pnutrition knowledge among participants of NEP at the workplace. According to the NQ, an interactive nutrition education had a higher impact on nutrition knowledge than a lecture programme.

    Full Text Available Carbonate deposits of members 1 to 2 of the Mila Group (Middle Cambrian in Central Alborz that call Deh-Sufiyan Formation in this research, were studied in Shahmirzad, Tueh-Darvar, Mila-Kuh and Deh-Molla sections. These sediments were deposited in four facies belts on a carbonate ramp including basinal environments, outer ramp (deep subtidal sequences, mid ramp (shallow subtidal to lower intertidal sequences, and inner ramp (shoal and upper intertidal to supratidal sequences. Various microbialites were recognized in the shallow-water sediments (includes subtidal and intertidal of this unit. Based on this study, microbial mats have various morphology of form and type of growth structure and inluding laminar to wavy-laminar, domal or hemispheroidal, bulbous, columnar, regular flabellate columns, unlaminated, loaf- to mound-shaped thrombolities. Facies associations of Deh-Sufiyan Formation are arranged in small-scale of peritidal, shallow subtidal, and deep subtidal cycles and microbial mats are the major features of them. The trends of vertical changes of facies in shallowing-upward and deepening-upward cycles and distribution of various types of microbialites in these cycles had been related to depostional environments and their postions on carbonate ramp. Basal classification method used in this study can provide valuable informations for application of microbiali mats in paleo-environmental and sequence stratigraphy analysis.

    2014-04-01

    Despite the prevalence of pornography use, and recent conceptualization of problematic use as an addiction, we could find no published scale to measure craving for pornography. Therefore, we conducted three studies employing young male pornography users to develop and evaluate such a questionnaire. In Study 1, we had participants rate their agreement with 20 potential craving items after reading a control script or a script designed to induce craving to watch pornography. We dropped eight items because of low endorsement. In Study 2, we revised both the questionnaire and cue exposure stimuli and then evaluated several psychometric properties of the modified questionnaire. Item loadings from a principal components analysis, a high internal consistency reliability coefficient, and a moderate mean inter-item correlation supported interpreting the 12 revised items as a single scale. Correlations of craving scores with preoccupation with pornography, sexual history, compulsive internet use, and sensation seeking provided support for convergent validity, criterion validity, and discriminant validity, respectively. The enhanced imagery script did not impact reported craving; however, more frequent users of pornography reported higher craving than less frequent users regardless of script condition. In Study 3, craving scores demonstrated good one-week test-retest reliability and predicted the number of times participants used pornography during the following week. This questionnaire could be applied in clinical settings to plan and evaluate therapy for problematic users of pornography and as a research tool to assess the prevalence and contextual triggers of craving among different types of pornography users.

    Full Text Available Objective. The aim of the study was an assessment of adolescent adaptability resources, necessary for the proper social functioning. Material and methods. The study was conducted in 2013-2014 by means of standardised tests, psychological questionnaires and a general questionnaire developed for the purpose of the study, which made it possible to obtain additional necessary data on the study group. Results. The study describes the study group in terms of attitudes and behaviour in relation to certain personality traits and external factors, which may affect the functioning of adolescents. Conclusions. Examined adolescents had good adaptability conducive to proper social functioning. It resulted both from individual personal predispositions as well as from the positive impact of the family and non-family environment. These observations confirm that adolescents require continuous interest and attention from adults and implementing measures to prevent impaired development of individuals and its negative social repercussions.

    In 1993 Albach investigated the long-term consequences of sexual abuse on psychological health. A group of abused women a a control group of nonabused women were asked to fill in a questionnaire assessing posttraumatic stress disorder (PTSD). For ethical reasons, the abused women were warned that filling in the questionnaire might be emotionally stressful. The control group did not receive this warning. The abused women scored higher on the questionnaire than the nonabused women. The warning they received may have influenced their reports. Our experiment investigated this. 101 psychology students were divided into two groups, one who received a warning and a control group who did not. The hypothesis was that people who had been previously warned would score higher on a PTSD questionaire than people who had not. There were, however, no significant differences in mean PTSD scores and no known initial differences between groups.

    2012-03-01

    The Perceptions of Conscience Questionnaire (PCQ) and the Stress of Conscience Questionnaire (SCQ) have previously been developed and validated within the 'Stress of Conscience Study'. The aim was to revalidate these two questionnaires, including two additional, theoretically and empirically significant items, on a sample of healthcare personnel working in direct contact with patients. The sample consisted of 503 healthcare personnel. To test variation and distribution among the answers, descriptive statistics, item analysis and principal component analysis (PCA) were used to examine the underlying factor structure of the questionnaires. Support for adding the new item to the PCQ was found. No support was found for adding the new item to the SCQ. Both questionnaires can be regarded as valid for Swedish settings but can be improved by rephrasing some of the PCQ items and by adding items about private life to the SCQ.

    The Evaluative Linguistic Framework (ELF) was developed to judge the quality of health care texts for patients, based on systemic functional linguistic theory. This approach considers key variables such as context and structure, known to be important for communication. Our objective was to adapt the ELF to evaluate the quality of self-report questionnaires. We reviewed the Health Literacy Questionnaire using the ELF. On the basis of these data, we drafted the preliminary version of the Evaluative Linguistic Framework for Questionnaires (ELF-Q) and applied it to English- and French-language versions of two arthritis self-report questionnaires and to Spanish, Dutch, and Turkish versions of an arthritis questionnaire. The developed ELF-Q was found to be effective for evaluating questionnaires in English and in four other languages. It contains nine items with new descriptions and assessment probes. These include overall organizational or generic structure of the questionnaire, metadiscourse (or text about the text), headings, rhetorical elements (function of each "move" or stage of the text in relation to the reader), the writer-reader relationship, technicality of vocabulary, lexical density (proportion of content words in the text), format, and overall judgment. We added assessment responses on a two- or three-point Likert scale to complement the assessment probes and make the intent and meaning of the probes fully explicit for the questionnaire developer or assessor. The ELF-Q is a framework practical to use for the development or assessment of any type of self-report questionnaire. Its application can identify features of a self-report questionnaire that could be improved to optimize its comprehensibility.

    To design and perform a face and content validation of a questionnaire to measure the competence of hospital RN to report medication incidents. Content and face questionnaire validation descriptive study. A review of the literature was performed for the creation of ítems. A panel of six experts assessed the relevance of the inclusion of each ítem in the questionnaire by calculating the position index; ítems with position index >0.70 were selected. The questionnaire was piloted by 59 RN. Finally, a meeting was convened with experts, in order to reduce the length of the piloted questionnaire through review, discussion and decision by consensus on each item. From the literature review, a battery of 151 ítems grouped into three elements of competence: attitudes, knowledge and skills was created. 52.9% (n=80) of the ítems received a position index > 0.70. The response rate in the pilot study was 40.65%. The median time to complete the questionnaire was 23:35minutes. After reduction by the experts, the final questionnaire comprised 45 ítems grouped into 32 questions. The NORMA questionnaire, designed to explore the competence of hospital RN to report medication incidents, has adequate face and content validity and is easy to administer, enabling its institutional implementation.

The rationale for the questionnaire is to bring together into one short instrument questions about two distinct domains – patients' reports of the outcomes of their care and how they experience care.Methods: The OEQ was developed from literature reviews, iterative drafting and discussion within the research group and cognitive testing with a sample of patients who had a hospital experience. Two validation studies were carried out with an eleven item OEQ. The goals of the studies were to examine response rates and to test specific hypotheses of how OEQ should relate to other variables normally collected in the two studies. In the first study, the OEQ was added to the follow-up questionnaires for patients (n=490 receiving surgery for hip or knee replacement or varicose vein procedures participating in the national Patient Reported Outcome Measures (PROMs program permitting the analysis of the OEQ against change scores for the measures obtained before and after surgery. In the second study the OEQ was included in a sample of patients (n=586 who had been selected to receive the National Health Service (NHS inpatient survey from three contrasting hospital trusts.Results: Results from study one provided consistent and substantial evidence of construct validity of OEQ particularly for those receiving hip or knee replacement. The OEQ sub-scales behaved differently and as predicted against other PROMs variables. Again hypotheses of how the two sub-scales regarding outcomes and experiences would relate to the existing domains of patient experience in the inpatient survey were broadly confirmed in study two

    Postal and electronic questionnaires are widely used for data collection in epidemiological studies but non-response reduces the effective sample size and can introduce bias. Finding ways to increase response to postal and electronic questionnaires would improve the quality of health research. To identify effective strategies to increase response to postal and electronic questionnaires. We searched 14 electronic databases to February 2008 and manually searched the reference lists of relevant trials and reviews, and all issues of two journals. We contacted the authors of all trials or reviews to ask about unpublished trials. Where necessary, we also contacted authors to confirm methods of allocation used and to clarify results presented. We assessed the eligibility of each trial using pre-defined criteria. Randomised controlled trials of methods to increase response to postal or electronic questionnaires. We extracted data on the trial participants, the intervention, the number randomised to intervention and comparison groups and allocation concealment. For each strategy, we estimated pooled odds ratios (OR) and 95% confidence intervals (CI) in a random-effects model. We assessed evidence for selection bias using Egger's weighted regression method and Begg's rank correlation test and funnel plot. We assessed heterogeneity among trial odds ratios using a Chi(2) test and the degree of inconsistency between trial results was quantified using the I(2) statistic. PostalWe found 481 eligible trials. The trials evaluated 110 different ways of increasing response to postal questionnaires. We found substantial heterogeneity among trial results in half of the strategies. The odds of response were at least doubled using monetary incentives (odds ratio 1.87; 95% CI 1.73 to 2.04; heterogeneity P textual representation of response categories (1.19; 95% CI 1.05 to 1.36), and giving a deadline (1.18; 95% CI 1.03 to 1.34).

    This study falls within the theoretical framework of the construct of the Efficient Personality. In this work, we present the study of validity and reliability of an original questionnaire made up of 60 items, applied to students from formative cycles of higher Professional Training. The questionnaire was reduced to 24 items, surpassing its initial .84 Cronbach alpha coefficient. Six first-order factors were obtained: Social Self-concept, Academic Self-concept, Solving Ability, Self-esteem, and Problem Coping. One second-order factor was obtained: Efficient Personality. The six-component factorial solution is similar both to the Spanish version for secondary school and to the Chilean versions for secondary and university populations, dividing the initial dimension of Self-concept into Self-concept and Self-esteem.

    Full Text Available Introduction: Evaluation of nurse-patient communication skills have been strongly emphasized in order to ensure the possibility of effective communication as well as assessment of the effect of communication skills training programs. Reaching this goal requires the use of standard instruments which is based on the native culture of the target group. Due to the absence of native instruments in this field, the aim of this study was to design and assess the validity and reliability of interpersonal communication skills, among nurses at Shiraz Educational Hospitals. Method: A mixed method (Qualitative, Quantitative was used in two phases. The first phase was designing a descriptive questionnaire for nurse-patient communication skills (consisting of “brain storming” and “Delphi quantitative Research Method”. The next phase was defining the validity and reliability of the questionnaire based on confirmatory factor analysis and Cronbach’s alpha. The target population for the first phase was 15 faculty members of Shiraz University of Medical Sciences and for the second phase, 130 members of nursing staff of both educational and private hospitals of Shiraz. The data were analyzed using SPSS 14 and LISREL software after fulfilling the questionnaires. Results: The findings of the study demonstrated the reliability of the nurse-patient communication skills questionnaires (α=0.810. Except for question No. 17, the others had a significant relationship with the agent based on their validity and T-value. Conclusion: Like other clinical skills, communication requires the theoretical knowledge, evaluation and practice. The findings of this study are the most important indicators from the nurses’ view point which can be assessed in terms of communication skills. These options, as demonstrated, had an acceptable reliability and validity.

    As the method for questionnaire studies, mail survey and interview survey are frequently used. The utility and validity of applying the Internet method to medical studies have yet to be fully evaluated. For the present investigation, we reviewed 36 Japanese original articles using Internet questionnaire reported through to April 2005. Although original papers using the Internet method have been increasing in recent years, they are still limited in number. There is comparatively much research on disease with many patients in youth and early manhood, such as allergic ailments (allergic rhinitis, atopic dermatitis, and hives). As compared with conventional methods, the advantages of the Internet approach are convenience for both investigators and respondents and the ability to quickly collect data. The disadvantage is that the user's age range is more concentrated. Since samples are extracted from individuals who are registered as monitors, a greater sampling error may occur as compared with a random sampling method. However, it is to be expected that continued explosive growth of the Internet would decrease the limitation in user's age. If more elderly people participate in questionnaire studies using the web, research into more illnesses should be facilitated. Considering the inherent advantage, it is thought that Internet method can become the leading tool for sociomedical and clinical research in the near future.

    Patient-reported outcome measures (PROMs) have the potential to be extremely valuable in the clinical care delivery for women who report heavy menstrual bleeding (HMB). Increasingly, studies on HMB have incorporated PROMs to evaluate the impact of bleeding on quality of life. These measures have included semiquantitative charts and pictograms, questionnaires to assess symptoms and impact on quality of life, and health-related quality of life questionnaires. Recent systematic reviews have highlighted inconsistency of outcome measurement across studies on HMB as a challenge limiting the interpretability of the body of literature and the ability to generate consensus on the relative effectiveness of treatment options. Consequently, research initiatives and international collaborations are working to harmonize outcome measurement. Harmonizing the use of questionnaires in research and clinical care has the potential to improve patient-centered care delivery for women with HMB and improve the generation of patient-focused evidence-based guidelines for the evaluation and treatment of HMB.

    The Cognitive Failures Questionnaire (CFQ) is used in ergonomics research to measure behavioural problems associated with attentiveness and memory in everyday life. CFQ scores have been related to constructs such as accident proneness and outcomes such as human error and psychological strain. The two-year test-retest reliability of the CFQ is reported together with the findings of factor analyses of CFQ data from 535 respondents. Evidence for the predictive and criterion validity and internal reliability of the CFQ is provided. Psychological strain was measured concurrently with CFQ on both testing occasions, two years apart. The test-retest reliability of the summated CFQ score was found to be 0.71, while for the General Health Questionnaire (GHQ-12) strain measure it was 0.32.The relative variance stability was five times greater for the CFQ than the GHQ, indicating that scores on these questionnaires are not covariates. The use of the CFQ as a measure of cognitive control capacity is also discussed. Ergonomists have long been interested in human error and the role of high work demands due to poor equipment design and excessive workload. The CFQ measures attentiveness in daily life and is shown to have excellent psychometric properties that make it suitable for use in both laboratory and field studies as a trait measure of attentiveness in daily life.

We discuss how such an adaptation could be supported by an analytical software solution and present the initial version of this solution. In the form of a case study, we discuss the scores from a personality questionnaire that was administered to a group of university students enrolled in an introductory programming course at the Faculty of Technical Sciences, University of Novi Sad, Serbia. During a non-mandatory workshop on programming, the participants completed the 48-item short-scale Eysenck Personality Questionnaire–Revised (EPQ– R. By using various exploratory and analytical techniques, we inspect the student EPQ–R scores and elaborate on the specificities of the participating student group. As part of our efforts to understand the broader relevance of different student personality traits in an academic environment, we also discuss how the EPQ–R scores of students could provide information valuable to the process of improving student learning and performance in university courses in ACSI.

    The aim of this study was to evaluate the usefulness of a short form of the WHOQOL questionnaire, the WHOQOL-BREF, which consists of 24 questions, in evaluating quality of life (QOL) in sarcoidosis patients. A group of 97 sarcoidosis patients and a matched group of 97 healthy controls took part in the study. Their QOL was examined by means of the WHOQOL-BREF, and the respiratory functions were measured in sarcoidosis patients. The WHOQOL-BREF revealed significantly poorer QOL of sarcoidosis patients in the domains of Physical and Psychological Health in comparison to healthy controls. In contrast, sarcoidosis patients perceived their QOL significantly better than healthy controls in the domains of Social Relations and Environment. Differences between sarcoidosis patients and healthy controls were found in several items from the WHOQOL-BREF and some of them were modified by gender. However, the WHOQOL-BREF did not prove to be a sensitive measure of fatigue, which is the most common symptom in sarcoidosis patients.

    Full Text Available Background and Aims: Allergic bronchopulmonary aspergillosis (ABPA is an immunological disorder caused by hypersensitivity against Aspergillus fumigatus. The pathogenesis of ABPA remains unknown. Few studies have investigated the role of environmental factors in pathogenesis of ABPA. Herein, we investigate the role of environmental factors in ABPA. Materials and Methods: In this prospective case-control study, consecutive patients with asthma (Aspergillus sensitized and unsensitized and ABPA were investigated using a standardized questionnaire to enquire into their demographic characteristics, clinical details, exposure to organic matter and living conditions (home environment, presence of moisture in the walls, and others. Asthma severity and control was assessed using the 2002 The Global Initiative for Asthma (GINA recommendations and asthma control test, respectively. Results: During the study period, 202 subjects of asthma (103 and 99 Aspergillus unsensitized and sensitized asthma, respectively and 101 ABPA with a mean (SD age of 35.3 (14.7 years were included. The baseline characteristics were similar in the two groups except for a higher prevalence of severe persistent asthma in the ABPA group (79% vs. 44%, P = 0.0001. No significant differences in environmental factors were noted in the ABPA population compared to asthmatic patients except for a higher rural residence in ABPA (47% vs. 66%, P = 0.007. Conclusions: The study found no significant environmental differences in ABPA compared to asthmatic patients. It is likely that environmental factors are not the primary pathogenetic factors in causation of ABPA.

Job Satisfaction Index is a validated measure to identify the components that influence those issues. A multi-faceted structured questionnaire study was conducted upon a cross-section of medical educators (n=160 serving two tertiary care teaching institutions under different management set-up. Multiple demographic features were independent variables whereas three (3 critical areas of satisfaction index (SI were outcome variables. All participants were interviewed using 15 item Likert response-based, modified job satisfaction scale. It was observed that total SI scores among doctors representing the private group remained marginally higher (P<0.05 while compared to the other group. The comparative analysis of SI scores in critical areas like availability of academic supports and job security remained higher among the private doctors than that of the government ones though not significant. However the private doctors remained marginally satisfied in terms of working environment. The study outcome necessitates appropriate intervention measures at the organizational levels.

    The aim of our study was to validate a Pediatric Voice Symptom Questionnaire (PVSQ) presenting with a parallel form for children and their parents. The items of the questionnaire were elaborated from the results of structured interviews with dysphonic children (DP) and normophonic children (NP) and their mothers and were tested for feasibility in a pilot study involving 42 normophonic children aged 5-13 years. The items were then administered in a test-retest mode to 333 children and their parents (154 boys and 179 girls with a mean age of 9 years, standard deviation: 1.8); 45 consulting DP, 34 nonconsulting dysphonics (NcDP), 163 NP, and 91 others. Classical statistical analyses and an item response modeling approach were used to analyze the results. High internal consistency and good test-retest stability were found. Significant differences between total score of the NP, DP, and NcDP groups were observed both in the children and the parents and also between parental and child score for the NP and NcDP groups (Pchild and parental scores were found only in the DP groups (r=0.478; Pdysphonia in the child population.

    Objectives It is not known which of the many asthma-specific quality of life (QoL) questionnaires best capture the lived experience of people with asthma. The objective of this study was to explore patients' views of three commonly used asthma-specific QoL questionnaires. Design Qualitative study using semistructured interviews. Setting Primary and secondary care in Brighton and Hove, UK. Participants 30 adult people with a physician-diagnosis of asthma who were asked to complete the Juniper Asthma Quality of Life Questionnaire (AQLQ-J), the Sydney Asthma Quality of Life Questionnaire (AQLQ-S) and the Living with Asthma Questionnaire (LWAQ) to elicit their views on the content validity of these. Results Thematic content analysis revealed a lack of congruence between the concerns of people with asthma and the questionnaire content in terms of missing (eg, allergies) and irrelevant (eg, smoky restaurants) content. The AQLQ-J was perceived as a ‘narrow’, ‘medical’ questionnaire focused on symptoms, the environment and functional ability. In contrast, the LWAQ and the AQLQ-S were perceived to be ‘non-medical’. The LWAQ was described as a ‘test’ and as a wide-ranging, embracing and holistic questionnaire. Its strong emotional focus was irritating to some. The AQLQ-S was described as a simple, quick and easy questionnaire, although there was a perception that it was lacking in depth. Conclusions Patient interviews highlighted strengths and shortcomings in the content validity of these three asthma-specific questionnaires. For patients, the AQLQ-S content seemed to be the most pertinent in its adequacy of coverage of medical, social and emotional aspects of health-related QoL in asthma. PMID:28007706

    To evaluate the psychometric properties of a questionnaire addressing psychosocial consequences of false-positive mammographic screening. The Consequences of Screening--Breast Cancer and Lung Cancer questionnaires target psychosocial consequences of false-positive cancer screening. The Consequences of Screening--Breast Cancer questionnaire and ten items not considered lung cancer specific from the Lung Cancer questionnaire have been adapted for use in mammographic screening in Sweden, but remain psychometrically untested. Instrument development paper with psychometric cross-sectional and test-retest design. Twelve scales of a Swedish questionnaire version were tested by the Rasch model and traditional psychometric methods. Women with false-positive (Group I, n = 640) and negative (Group II, n = 802) screening mammography responded to the study questionnaire and the Nottingham Health Profile during 2009-2011. Iterative analyses resulted in nine scales demonstrating Rasch model fit, but all scales exhibited poor targeting with relatively large floor effects. Corrected item-total correlations exceeded the recommended criterion. Score differences between Groups I and II and correlations with Nottingham Health Profile sections followed an expected pattern. Cronbach's α and test-retest reliability was acceptable for group-level assessments for ten and seven scales, respectively. Five scales (Sense of dejection, Anxiety, Behavioural, Sleep and Existential values) of the Swedish questionnaire version demonstrated the best psychometric properties. Other scales should be used more cautiously. Although filling an important gap, causes of concern were identified across scales. The questionnaire should therefore be considered for group-level assessments rather than for measurement of individual degrees of psychosocial consequences. © 2014 John Wiley & Sons Ltd.

    ABSTRACT Objective Compulsive exercise is a well‐known feature in eating disorders. The Exercise and Eating Disorder (EED) self‐report questionnaire was developed to assess aspects of compulsive exercise not adequately captured by existing instruments. This study aimed to test psychometric properties and the factor structure of the EED among women with eating disorders and a control group. Method The study included 449 female participants, including 244 eating disorders patients and 205 healthy controls. The patient group consisted of 32.4% (n = 79) AN patients, 23.4% (n = 57) BN, 34.4% (n = 84) EDNOS and 9.8% (n = 24) with BED diagnosis. Results The analyses confirmed adequate psychometric properties of the EED, with a four‐factor solution: (1) compulsive exercise, (2) positive and healthy exercise, (3) awareness of bodily signals, and (4) weight and shape exercise. The EED discriminated significantly (p < .001) between patients and controls on the global score, subscales, and individual items. Test‐retest reliability was satisfactory (r = 0.86). Convergent validity was demonstrated by high correlations between the EED and the Eating Disorder Examination Questionnaire (EDE‐Q; r = 0.79). Discussion The EED is the first clinically derived, self‐report questionnaire to assess compulsive exercise among ED patients. The EED offers assessment that has broader clinical utility than existing instruments because it identifies treatment targets and treatment priorities. © 2015 Wiley Periodicals, Inc.

    In the health sector, anywhere in the world nurses are one of the most exposed groups to violence. However, it is not obvious that psychiatric nurses (PNs) are more exposed to aggression and burnout. To determine the nature and effects of aggressive acts towards nursing staff in psychiatric and other medical services in Poland. Various questionnaires (Stress at Work Scale, General Health Questionnaire, Maslach Burnout Inventory, Work Satisfaction Scale), were distributed among psychiatric (N=78) and non-psychiatric nurses (N-PNs) (N=335). A 92.6% response rate was achieved. Significant differences were found between PNs and non-psychiatric counterparts with respect to their experiences of violence. The most frequently reported incident was verbal abuse, followed by threats and physical assault. Patients were significantly more frequent perpetrators in psychiatric wards than in others. The level of intra-staff aggression did not significantly vary between groups, neither did the level of work satisfaction and absenteeism. The frequency of violent acts and stress related to them point out the strong need for the development of preventive programs to address the issue of violence at work.

    Background The transtheoretical model (TTM) has been widely used to promote healthy behaviors in different groups. However, a questionnaire has not yet been developed to evaluate the health behaviors that medical practitioners often consider in individuals with cancer or at a high risk of developing cancer. Purpose The aim of this study was to construct and validate the Health Behavior and Stages of Change Questionnaire (HBSCQ), which is based on the TTM and health recommendations related to risk and factors that protect against cancer. Methods Content validity was conducted in two phases (qualitative and quantitative). Item difficulty index, item discrimination index, and discrimination coefficient were obtained based on the classical test theory. Finally, Cronbach’s alpha was used. Results Measure of concordance showed scores considered adequate and excellent. The item discrimination index obtained a rating of “excellent” and suggested the preservation of all items. The discrimination coefficient scores are >0.74. The global internal consistency of the HBSCQ was 0.384. HBSCQ specification between groups of internal consistency for the sample of men was 0.712 and that for the sample of women was 0.378. Conclusion/implications for practice The HBSCQ represents a proposal for a fast, simple, and innovative screening test, which aims to identify persons who may benefit from interventions to promote health behaviors delimited to the stage of change.

    To identify factors that contribute to the high variability of the rates of use of placebo interventions reported in questionnaire surveys, the author investigated the effect of the explicit use of the word "placebo" in questionnaire surveys on placebo use in clinical practice on the results obtained. 190 primary care physicians in Poland were divided randomly into two groups. The groups received a questionnaire in which either the word placebo or the term "nonspecific methods of treatment" was used. The respondents who were asked explicitly about the use of placebo interventions declared that they never used placebo interventions significantly more often than participants asked about the use of nonspecific treatment methods. Moreover, the former reported significantly rarer use of placebo interventions than the latter. The study demonstrates that differences in the wording of questions in questionnaire surveys on placebo use can create statistically significant differences in results.

This term denotes the absence of significant disease and disabilities, maintenance of high levels of physical and cognitive function, and preservation of social and productive activities. Preservation of an active lifestyle is considered an effective means through which everyday competence can be attained. In this context, it is crucial to obtain ratings of modern day older adults’ everyday competence by means of appropriate assessments. Here, we introduce the Everyday Competence Questionnaire (ECQ, designed to assess healthy older adults' everyday competence.Methods: The ECQ includes 17 items, covering housekeeping, leisure activities, sports, daily routines, manual skills, subjective well-being, and general linguistic usage. The ECQ was administered to a population of 158 healthy subjects aged 60–91 years, who were divided into groups on the basis of their physical activity. These groups were community-dwelling subjects, those living independently and having a sedentary lifestyle, those living independently but characterized by a general lifestyle without any noteworthy physical activity, and those living independently and exercising regularly. Age, gender, and education levels were balanced between the groups.Results: Using the ECQ, we could identify and distinguish different everyday competence levels between the groups tested: Subjects characterized by an active lifestyle outperformed all other groups.
