    2013-01-01

    Orientation: Questionnaires, particularly the Utrecht Work Engagement Scale (UWES-17), are an almost standard method by which to measure work engagement. Conflicting evidence regarding the dimensionality of the UWES-17 has led to confusion regarding the interpretation of scores. Research purpose: The main focus of this study was to use the Rasch model to provide insight into the dimensionality of the UWES-17, and to assess whether work engagement should be interpreted as one single overall...

    Research purpose: This study assesses the Differential Item Functioning (DIF of the Utrecht Work Engagement Scale (UWES-17 for different South African cultural groups in a South African company. Motivation for the study: Organisations are using the UWES-17 more and more in South Africa to assess work engagement. Therefore, research evidence from psychologists or assessment practitioners on its DIF across different cultural groups is necessary. Research design, approach and method: The researchers conducted a Secondary Data Analysis (SDA on the UWES-17 sample (n = 2429 that they obtained from a cross-sectional survey undertaken in a South African Information and Communication Technology (ICT sector company (n = 24 134. Quantitative item data on the UWES-17 scale enabled the authors to address the research question. Main findings: The researchers found uniform and/or non-uniform DIF on five of the vigour items, four of the dedication items and two of the absorption items. This also showed possible Differential Test Functioning (DTF on the vigour and dedication dimensions. Practical/managerial implications: Based on the DIF, the researchers suggested that organisations should not use the UWES-17 comparatively for different cultural groups or employment decisions in South Africa. Contribution/value add: The study provides evidence on DIF and possible DTF for the UWES-17. However, it also raises questions about possible interaction effects that need further investigation.

    A test site for the design, implementation and operation of an underground in-situ bioleaching unit has been installed by the „Biohydrometallurgical Center for Strategic Elements" at the research and education mine "Reiche Zeche" of Technical University Bergakademie Freiberg. For this purpose an ore vein block will be developed and mined with the bio-hydrometallurgical in-situ leaching technology. As a site survey an underground seismic tomography experiment has been performed to investigate the spatial distribution of the ore vein within this block consisting mainly of gneiss and with dimensions of about 30 x 10 meters. The experiment was performed with a sledgehammer as source and 76 three-component receivers with source and receiver point intervals of about 1 m surrounding the approximately rectangular block. High precision laser scanning was performed to obtain accurate source and receiver positions which was particularly necessary to obtain reliable results due to the generally high wave velocities of the gneiss. The resulting seismic data set showed a high signal-to-noise ratio with clear first arrivals which were picked for all source and receiver combinations and subsequently used as input to a first-arrival tomographic inversion scheme. The resulting velocity model has very good ray coverage and shows well resolved high- and low-velocity regions within the block. These regions can be clearly assigned to mapped outcrops of the ore vein along the galleries surrounding the block, including a correlation of low velocities to fractured rock parts as well as high velocities to the undisturbed ore vein core, respectively. In summary the obtained velocity model and the inferred spatial distribution of the ore vein provides a good basis for planning and implementing the actual ore mining step using the envisaged bioleaching technology.

  4. Dimensionality of the UWES-17: An item response modelling analysis

    Deon P. de Bruin

    2013-10-01

    Research purpose: The main focus of this study was to use the Rasch model to provide insight into the dimensionality of the UWES-17, and to assess whether work engagement should be interpreted as one single overall score, three separate scores, or a combination. Motivation for the study: It is unclear whether a summative score is more representative of work engagement or whether scores are more meaningful when interpreted for each dimension separately. Previous work relied on confirmatory factor analysis; the potential of item response models has not been tapped. Research design: A quantitative cross-sectional survey design approach was used. Participants, 2429 employees of a South African Information and Communication Technology (ICT company, completed the UWES-17. Main findings: Findings indicate that work engagement should be treated as a unidimensional construct: individual scores should be interpreted in a summative manner, giving a single global score. Practical/managerial implications: Users of the UWES-17 may interpret a single, summative score for work engagement. Findings of this study should also contribute towards standardising UWES-17 scores, allowing meaningful comparisons to be made. Contribution/value-add: The findings will benefit researchers, organisational consultants and managers. Clarity on dimensionality and interpretation of work engagement will assist researchers in future studies. Managers and consultants will be able to make better-informed decisions when using work engagement data.

    2010-08-01

    The present study investigated the factorial validity of the Utrecht Work Engagement Scale (UWES) among 1266 participants from ten different occupational groups. Confirmatory factor analyses of the total sample, as well as multi-group analyses and analyses of each of the ten occupational groups separately, indicated that a three-dimensional model of both the UWES-17 and the short version, UWES-9, provided a better fit to the data than a one- and two-dimensional model. The results of multi-group analyses and analyses of each of the groups separately, indicated that with a few exceptions, the three-factor model of work engagement provided the best fit. Results indicated factorial invariance and the internal consistencies were acceptable. The fit of the UWES-9 was slightly better than the UWES-17. It is concluded that the Norwegian short version may be recommended over the UWES-17.

    Full Text Available This article analyses Uwe Janson’s 2006 TV-film adaptation of Peer Gynt. This 81-minute-long film was shot on the island of Usedom in the Baltic Sea and makes extensive use of the landscape in its investigation of identity. The article examines the effects of limiting the geographical space of Peer’s journey of self-discovery and pays particular attention to the symbolic use of boats. It also explores how Janson mirrors the self-reflexivity of Ibsen’s work and maintains the romantic/anti-romantic dichotomy evident in the poetic text.

    Full Text Available Work engagement is defined as a positive, affective-motivational state of work-related well-being characterized by vigor, dedication and absorption. The Utrecht Work Engagement Scale (UWES is the most frequently used measure of work engagement. The aim of this study was to analyze the psychometric properties of the Serbian versions of the UWES-17 and UWES-9. The sample consisted of 860 employees from a number of organizations and jobs across Serbia. Based on the UWES-17 findings, the data confirm both the three-factor and one-factor solutions by giving a slight advantage to the three-factor solution. As for the UWES-9, based on the PCFA and CFA, the one-factor solution was obtained as the preferred one. Taking into account the UWES-9 reliability and correlation patterns of its subscales with other well-being variables, both one- and three-factor solutions of the UWES-9 are suggested for future research. Serbian versions of both the UWES-17 and UWES-9 have satisfactory psychometric properties with high reliability, factorial structure in line with the theoretical model, and good predictive validity. The study contributes to enhanced understanding of work engagement by offering an insight from the Serbian cultural and economic context, significantly different from the UWES originating setting. There is still a need for exploring how employees from Serbia conceptualize work engagement, as well as for further, more stringent investigating of the cultural invariance of the UWES factorial structure.

    Full Text Available Objective: The present study aims to evaluate the items, and respective dimensions, of the Utrecht Work Engagement Scale (UWES-17 of Schaufeli e Bakker (2009, when applied to social workers exercising their profession in Portugal (UWES-17. Method: The Portuguese version of the UWES was applied to a sample of 1369 Portuguese social workers, 94% of which female and 6% male, with an average age of 39 years (standard deviation = 8,99. The most frequent academic qualification is graduation (63,8% and in terms of professional activity they had, in average terms, 12,99 years of experience (standard deviation = 8,28. The reliability of the scale was assessed using the Chronbach alpha coefficient and the validity using the exploratory factorial analysis. Quantitative methodological research was used. Results: The results obtained agree with the values presented in previous studies regarding their internal consistency, both of the 17 items that make up the scale and of its three dimensions ("force", "dedication" and "absorption". The UWES-17 in this study presents a factorial structure of three factors, just like the original study, but the constitution of the items of each dimension is different. The UWES-17 scale presents good psychometric characteristics and good internal consistency. Conclusions: The UWES-17 scale presents good psychometric characteristics and good internal consistency.

    Full Text Available This article aims to analyze the psychometric properties of the Russian version of the Utrecht Work Engagement Scale (UWES-9 by using a sample of 1783 employees of a large Russian organization. We conducted a series of Confirmatory Factor Analysis (CFA tests of the factorial structure and the configural, metric, scalar, factor variance, factor covariance, and factor means invariances of the model across gender and age groups. The validity of the Russian version of the UWES-9 was investigated by study- ing its relationship with burnout, job satisfaction, life satisfaction, and turnover inten- tion. The CFA showed that both the 1-factor and the 3-factor models of the UWES-9 fit well with the data, but the 3-factor model demonstrates a significantly better fit. however, the differences are minor; therefore, in practical terms, the models are iden- tical. Thus the Russian version of the UWES-9 can be used both as a three-scale mea- surement and as a single scale of work engagement. Results from the multi-group CFA provided evidence of factorial invariance of the 3-factor model across gender and age groups. Internal consistencies of the vigor, dedication, and absorption subscales are acceptable. The results also suggested the convergent, discriminant, and incremental validity of the UWES-9, as shown by its relationship with burnout, job satisfaction, life satisfaction, and turnover intention. The article also discusses the differences in levels of work engagement within different gender and age groups. Overall, the results show that the Russian version of the UWES-9 demonstrates acceptable psychometric properties comparable with the original version and those in other languages. The Russian version of the UWES-9 can therefore be recommended for use in research and practice.

A Portuguese version of the instrument was applied to a convenience sample of 3,887 rescue workers (50% nurses, 39% firefighters, and 11% police officers. Work engagement levels were moderate to high, with firefighters being the highest and nurses being the lowest engaged. Psychometric properties were evaluated in the three-factor original structure revealing acceptable fit to the data in the UWES-17, although the UWES-9 had better psychometric properties. Given the observed statistically significant correlations between the three original factors, we proposed a 2nd hierarchal structure that we named work engagement. The UWES-9 first-order model obtained full uniqueness measurement invariance, and the second-order model obtained partial (metric second-order invariance.

    de Bruin, Gideon P; Henn, Carolina M

    2013-06-01

    Despite wide-spread use, questions remain about the dimensionality of the 9-item Utrecht Work Engagement Scale (UWES-9). Theoretical underpinnings of the UWES-9 point toward a hierarchical structure with a general factor and three group or primary factors: Dedication, Vigor, and Absorption. To date, researchers have failed to model the general factor, which contributes to the lack of consensus about the dimensionality of the scale. Bi-factor analysis was used to demonstrate the presence of a very strong general factor and, in comparison, two weak group factors. The results shed additional light on the meaning of the work engagement construct. The implications for research with the UWES-9 are discussed.

    The aim of this paper is to present a revision of international versions of the Utrecht Work Engagement Scale and to describe the psychometric properties of a Portuguese version of the UWES-9 developed simultaneously for Brazil and Portugal, the validity evidence related with the internal structure, namely, Dimensionality, measurement invariance between Brazil and Portugal, and Reliability of the scores. This is the first UWES version developed simultaneously for both countries, and it is an important instrument for understanding employees' work engagement in the organizations, allowing human resources departments to better use workforces, especially when they are migrants. A total of 524 Brazilian workers and 522 Portuguese workers participated in the study. Confirmatory Factor Analysis, group comparisons, and Reliability estimates were used. The use of workers who were primarily professionals or administrative support, according to ISCO-08, reinforced the need to collect data on other professional occupations. Confirmatory factor analysis showed acceptable fit for the UWES-9 original three-factor solution, and a second-order factor structure has been proposed that presented an acceptable fit. Full-scale invariance was obtained between the Portuguese and Brazilian samples, both for the original three-factor first-order and second-order models. Data revealed that Portuguese and Brazilian workers didn't show statistically significant differences in the work engagement dimensions. This version allows for direct comparisons of means and, consequently, for performance of comparative and cross-cultural studies between these two countries.

Los resultados obtenidos muestran que el modelo de dos factores presenta mejores índices de ajuste que el de uno y tres factores, por lo que se concluye que la estructura de dos factores es la más apropiada. De igual forma, los resultados llevan a concluir que la escala UWES-S 9 puede ser utilizada para estudiar el engagement en el contexto ecuatoriano.

    Engagement is defined as a positive, fulfilling, work-related state of mind that is characterized by vigor, dedication, and absorption. The main purpose of this study was to examine the psychometric properties of the Utrecht Work Engagement Scale (UWES). Data from a sample of health care workers (N=948) were used to test four propositions concerning dimensionality, internal consistency and construct validity. The UWES Italian version and the Multidimensional Organizational Health Questionnaire (MOHQ) were administered to the subjects (a subsample of 225 health care workers also completed the Maslach Burnout Inventory). The factorial structure has been examined through a series of Explorative Factor Analysis (AFE) and Confirmatory Factor Analysis (CFA). As in the original version, we found a three factor solution. Internal consistency indexes were satisfactory. In addition, the correlations between UWES, MOHQ and MBI revealed a good construct validity. It is concluded that the Italian Version of the UWES has acceptable psychometric properties and that the instrument can be used in studies on positive organizational behavior.

    Our purpose was the psychometric evaluation of the German version of the Utrecht Work Engagement Scale-9 (UWES-9), a self-assessment tool measuring work-related resources consisting of 9 items. Based on a sample of 179 patients with hematological malignancies in in-patient and rehabilitative oncological settings, we tested the dimensional structure by confirmatory and explorative factor analysis. We further evaluated reliability, item characteristics, and construct validity of the UWES-9. The confirmatory factor analysis showed acceptable fit for both a 1-dimensional factor structure and the original 3-factor model. Based on an explorative principal component analysis, we were able to replicate the 1-dimensional factor accounting for 67% of the total variance and showing very high internal consistency (α=0.94) and high factor loads (0.73-0.88). The construct validity was further supported by significant positive correlations between work engagement and meaning of work, corporate feeling, commitment to the workplace, and job satisfaction. The German version of the UWES-9 shows good psychometric qualities in measuring dedication to work in patients with hematological malignancies in in-patient and rehabilitative oncological settings. © Georg Thieme Verlag KG Stuttgart · New York.

  14. An Animal-Centered Perspective on Colonial Oppression: Animal Representations and the Narrating Ox in Uwe Timm’s ‘‘Morenga’’ (1978

    Directory of Open Access Journals (Sweden)

    Steffen Röhrs

    2017-02-01

    Full Text Available As a result of its topic and its narrative style, Uwe Timm’s novel ‘Morenga’ (1978 marks an important step in the development of postcolonial German literature. The main theme of the book is the bloody suppression of the Herero and the Nama uprisings through the German army in South-West Africa at the beginning of the 20th century. With recourse to historical and fictional documents and by using different narrative perspectives, the text achieves a plurality of voices and thereby destabilizes a one-dimensional view on colonialism. The present article discusses the functions of the nonhuman animals appearing in ‘Morenga’. It is assumed that the animal representations are an essential part of the plot and underscore the criticism of colonial rule in a narrative manner too. The novel contains several descriptions of suffering animals and links them to the harm of the Herero and the Nama in order to point out the ruthlessness of the colonists. Moreover, the book features a story-telling ox, which initiates a reflection process about possible ways of narrating colonial history. The talking ox adds a specific animal-centered perspective on colonial oppression and raises questions about emancipation, self-determination, and the agency of the nonhuman ‘other’

    2015-12-01

    Full Text Available The paper concentrates on selected passages from Uwe Johnsonʼs opus magnum, Jahrestage (Anniversaries, in which the Prague Spring and the events of 1968 play a key role, and develops some ideas on how narrations of history and critique of language can jointly (as a translation of sorts be understood as a critical approach to what is taken to be the present and the reality of the past. It is argued that Hannah Arendtʼs notion of the unpredictability of the future and of the event variously influenced the modalities of narration as employed by Johnson. The central issue of Jacques Derridaʼs Prague lecture on how a city determines ‘our’ modes of (self-preception and how a location can be grasped and ‘dated’ in writing is put to use in order to develop a singular perspective on some neglected aspects in Johnsonʼs work. Johnson’s novel and its commentaries form a diverse reflection on time, reality, and the media which can affirm its contemporaneity when understood as exemplary in contesting, by the voice of literature, the functionalization of history and its narrative.

    Directory of Open Access Journals (Sweden)

    Caroline Rupprecht

    2010-01-01

    Full Text Available This article analyzes the writings of East German author Uwe Johnson (1934-84 in terms of his experimental style—specifically transitions between descriptive passages—in conjunction with maternal imagery, as discussed through reference to Susan Suleiman’s concept of a “1.5 generation” of Holocaust survivors. A non-Jewish German author, Johnson addresses German history from the position of the perpetrators, yet born in 1934, he experienced National Socialism from the point of view of a child. In his tetralogy, Anniversaries: From the Life of Gesine Cresspahl (1970-83, feelings of guilt and attempts to understand the German past are negotiated through the maternal figure. This figure is linked, in turn, to water as both a structural and symbolic element throughout the novel. As this article demonstrates, the effect of “blurred boundaries” is achieved through water, which functions as paradigm for the mother-daughter relationship: the narrator-protagonist Gesine’s memory is shaped by the experience of near-drowning before the eyes of her mother, Lisbeth, who commits suicide via self-immolation during Reichskristallnacht . As this article concludes, the author himself seems caught in the predicament of Suleiman’s 1.5 Generation, where perception is blurred, and immersing oneself in (imaginary bodies of water becomes a response to the madness of fascism.

    Plaice, Caroline; Lloyd, Jon; Shaw, Pauline

    2017-03-01

    The aim of this research was to explore the library and information needs of health and social care students whilst on placement. Both desk and primary research were conducted and included an online questionnaire to students and semi-structured interviews. The questionnaire was completed by 252 students from a variety of programmes, equivalent to a 10% response rate. The results indicate a wide range of factors impacting on the library and information experiences of students. Whilst differences in the availability of a physical library in hospital or community locations still exist, these are mitigated by technology and a preference for home study. A significant result is that 77% (n = 193) of students on placement study at home, using a variety of Internet-connected devices. This highlights a marked change in practice and underlines the need for mobile-compliant e-resources and accessible at-a-distance services. As a result of this research, practical recommendations on how library support can be improved were developed including enhanced collaboration and learning with NHS colleagues, and knowledge sharing with other departments within the University who support our students. © 2017 Health Libraries Group.

    Based on the costs-by-cause principle everybody has to be responsible for the environmental damage produced. Accordingly the electricity supply companies should have to pay for the dismantling of nuclear power plants and the radioactive waste disposal. The implementation of a fond under public law seems to be an adequate solution. Critical arguments concerning the costs-by-cause principle shows that instead of a constrained enforcement of this principle a solution in the sense of the society as a whole should be in the focus.

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

However, despite its popularity, the UWES is not free from controversy concerning its factorial validity. In this paper, 21 research studies on both UWES-9 and UWES-17 factorial validity within the confirmatory factor analysis (CFA) approach have been reviewed in order to answer the question as to which of the UWES factorial structures displays greater validity. The originally proposed threefactor structure of the UWES has been recognized as superior in 6 studies. In further 6 studies, the UWES structure with 1 general factor has been found to be superior. In 8 studies, the authors have concluded that the one- and three-factor structures could be considered equivalent. One study has failed to confirm either the one- or three-factor structure of the UWES. These ambiguous results from studies focusing on the UWES factorial validity are puzzling because they not only indicate a lack of validity for the UWES as a measurement tool but might also challenge the whole concept of work engagement as a three-factor structure of dedication, vigor and absorption.

    Kulikowski, Konrad

    2017-10-11

    Work engagement, as conceptualized by the Utrecht Work Engagement Scale (UWES), is a work-related positive state of mind that is characterized by vigour, dedication and absorption; however, it still remains unclear how many dimensions work engagement comprises. This study tested the factorial validity of 11 different UWES factorial models that are available in the literature using a confirmatory factor analysis approach on a large sample of multi-occupational Polish employees (N = 1420). The two-factor UWES-6, comprising vigour and dedication, was found to be reliable and remained invariant across samples drawn from four different organizational positions. It also presented a better fit than the three-factor UWES-9, which is a scale used as a standard in contemporary research on work engagement. The findings suggest that the three-factor UWES-9 might not be an optimal measure of work engagement in Poland.

    The objective of the current study was to examine the psychometric properties of the Nepalese version of the Utrecht Work Engagement Scale (UWES-N) in a sample of hospital nurses. Registered nurses from three hospitals in Nepal (total N=438) voluntarily completed a self-administered paper-and-pencil questionnaire. Confirmatory factor analysis revealed that the hypothesized three-factor model of the 9-item version of the UWES-N (UWES-N-9) fitted the data best. The internal consistency of the scale was acceptable. Work engagement was positively related to job satisfaction, job performance, happiness and health, and it was negatively related to psychological distress, confirming its construct validity. In conclusion, the findings of our study indicated that the UWES-N-9 has satisfactory psychometric properties and provided supportive evidence for use of the UWES-N-9 in the Nepalese context.

    Full Text Available This study examines the concept of volunteer work engagement in a sample of 334 community health workers in Bonthe District, Sierra Leone. Structural equation modelling was used to validate both the 9-item and the 17-item Utrecht Work Engagement Scale (UWES-9 and UWES-17, respectively. Results assessing the UWES-17 invalidated the three-factor structure within this cohort of community health workers, as high correlations were found between latent factors. Findings for the validity of the UWES-9 were largely consistent with those of the UWES-17. Model fit for the UWES-9 were generally equivalent for the one-factor, three-factor, and bifactor solutions, however the three-factor model was once again rejected due to high factor correlations. Based on these results, the current sample provides evidence that work engagement is best represented as a unidimensional construct in this context. Findings are considered alongside previous research to offer support for the utilization of the shortened UWES-9 in this context, as it appears to provide a good representation of work engagement and possess a parsimonious unidimensional scoring scheme.

    Full Text Available The objectives of this research were to validate the Utrecht Work Engagement Scale (UWES for the South African Police Service (SAPS and to determine its construct equivalence and bias in different race groups. A cross-sectional survey design was used. Stratified random samples (N = 2396 were taken of police members of nine provinces in South Africa. The UWES and a biographical questionnaire were administered. Structural equation modelling confirmed a 3-factor model of work engagement, consisting of Vigour, Dedication and Absorption. These three factors have acceptable internal consistencies. Exploratory factor analysis with target rotations showed equivalence of the three factors for different race groups in the SAPS. No evidence was found for uniform or non-uniform bias of the items of the UWES for different race groups.

    Work engagement is a positive work-related state of fulfillment characterized by vigor, dedication, and absorption. Previous studies have operationalized the construct through development of the Utrecht Work Engagement Scale. Apart from the original three-factor 17-item version of the instrument (UWES-17), there exists a nine-item shortened revised version (UWES-9). The current study explored the psychometric properties of the Chinese version of the Utrecht Work Engagement Scale in terms of factorial validity, scale reliability, descriptive statistics, and construct validity. A cross-sectional questionnaire survey was conducted in 2009 among 992 workers from over 30 elderly service units in Hong Kong. Confirmatory factor analyses revealed a better fit for the three-factor model of the UWES-9 than the UWES-17 and the one-factor model of the UWES-9. The three factors showed acceptable internal consistency and strong correlations with factors in the original versions. Engagement was negatively associated with perceived stress and burnout while positively with age and holistic care climate. The UWES-9 demonstrates adequate psychometric properties, supporting its use in future research in the Chinese context.

    To investigate the Maslach Burnout Inventory-General Survey (MBI-GS) and the Utrecht Work Engagement Scale (UWES) for their ability to identify non-sicklisted employees at increased risk of long-term sickness absence (LTSA). One-year prospective cohort study including 4,921 employees participating in occupational health surveys in the period 2008-2010. The MBI-GS and UWES were part of the health survey questionnaire and LTSA in the year following the health survey was retrieved from an occupational health register. Associations of baseline MBI-GS and UWES scores with LTSA during 1-year follow-up were stratified by the cause (mental, musculoskeletal, and other somatic illness) of LTSA. Discrimination was assessed by the area (AUC) under the receiver operating characteristic curve and considered practically useful for AUC ≥0.75. During 1-year follow-up, 103 employees (2%) had LTSA due to mental (N = 43), musculoskeletal (N = 31), or other somatic (N = 29) illness. MBI-GS scores were positively and UWES scores negatively associated with mental LTSA, but not musculoskeletal or other somatic LTSA. Discrimination between employees at high and low risk of mental LTSA was moderate: AUC = 0.68 for the MBI-GS and AUC = 0.70 for the UWES. Discrimination did not improve when the MBI-GS and UWES were used simultaneously. The MBI-GS and UWES predicted future mental LTSA in non-sicklisted employees, but discrimination was not practically useful for identifying employees at high risk of LTSA. However, both instruments could be used to select employees for further assessment of mental LTSA risk.

    The present study was aimed at assessing the validity and the reliability of the Sinhala version of the Utrecht Work Engagement Scale-Student Version (UWES-S) among collegiate cycle students in Sri Lanka. The 17-item UWES-S was translated to Sinhala and the judgmental validity was assessed by a multi-disciplinary panel of experts. Construct validity of the UWES-S was appraised by using multi-trait scaling analysis and exploratory factor analysis (EFA) on data obtained from a sample of 194 grade thirteen students in the Kurunegala district, Sri Lanka. Reliability of the UWES-S was assessed by using internal consistency and test-retest reliability. Except for item 13, all other items showed good psychometric properties in judgemental validity, item-convergent validity and item-discriminant validity. EFA using principal component analysis with Oblimin rotation, suggested a three-factor solution (including vigor, dedication and absorption subscales) explaining 65.4% of the total variance for the 16-item UWES-S (with item 13 deleted). All three subscales show high internal consistency with Cronbach's α coefficient values of 0.867, 0.819, and 0.903 and test-retest reliability was high (p valid and a reliable instrument to assess work engagement among collegiate cycle students in Sri Lanka.

    Full Text Available El documento –primera y segunda parte- forma parte de la producción del Proyecto Nro. 1748 del CIUNSa.: “Narrativa biográfica y motivación para el aprendizaje. A la búsqueda de pistas para repensar la problemática del ingreso universitario”. Se trata de dar cuenta de las razones por las cuales se centra la indagación acerca del ingreso a la universidad en la motivación de los estudiantes y de precisar el sentido en que se entiende el término, tomando para ello diferentes fuentes bibliográficas provenientes de distintos campos disciplinares. Con esta finalidad se reseña y comenta la producción de Ana Abramowski sobre su concepto de nopodermiento escolar; se revisan los más importantes modos de intervención motivacional en el aula expuestos por Antonio Huertas y se expone la diferenciación entre motivación externa e interna desarrollada por la psicología dialéctica rusa. Se funda sobre estas conceptualizaciones, desde una perspectiva compleja del conocimiento y un enfoque socio-histórico del desarrollo psicológico humano, una definición de motivación que se conjuga con la problematización del concepto de internalización como apropiación y como dominio, tomando las ideas bajtineanas de palabra autorizada y palabra internamente persuasiva que dan lugar a la categoría de resistencia. Surge de ello el interrogante sobre los posibles efectos motivadores de la apropiación y el dominio de las formas culturales de mediación y retomando los paralelismos planteados por Abramowski entre sistema productivo y educación, se reflexiona sobre el papel de la educación en la selección de los sujetos más aptos para el sistema económico capitalista.

  8. Validation of a δ2Hn-alkane-δ18Ohemicellulose based paleohygrometer: Implications from a climate chamber experiment

    Leaf wax-derived biomarkers, e.g. long chain n-alkanes and fatty acids, and their hydrogen isotopic composition are proved to be of a value in paleoclimatology/-hydrology research. However, the alteration of the isotopic signal as a result of the often unknown amount of leaf water enrichment challenges a direct reconstruction of the isotopic composition of paleoprecipitation. The coupling of ^2H/^1H results of leaf wax-derived biomarkers with 18O/16O results of hemicellulose-derived sugars has the potential to overcome this limitation and additionally allows reconstructing relative air humidity (RH) (Zech et al., 2013). This approach was recently validated by Tuthorn et al. (2015) by applying it to topsoil samples along a climate transect in Argentina. Accordingly, the biomarker-derived RH values correlate significantly with modern actual RH values from the respective study sites, showing the potential of the established 'paleohygrometer' approach. However, a climate chamber validation study to answer open questions regarding this approach, e.g. how robust biosynthetic fractionation factors are, is still missing. Here we present coupled δ2Hn-alkane-δ18Ohemicellulose results obtained for leaf material from a climate chamber experiment, in which Eucalyptus globulus, Vicia faba and Brassica oleracea were grown under controlled conditions (Mayr, 2003). First, the 2H and 18O enrichment of leaf water strongly reflects actual RH values of the climate chambers. Second, the biomarker-based reconstructed RH values correlate well with the actual RH values of the respective climate chamber, validating the proposed 'paleohygrometer' approach. And third, the calculated fractionation factors between the investigated leaf biomarkers (n-C29 and n-C31 for alkanes; arabinose and xylose for hemicellulose) and leaf water are close to the expected once reviewed from the literature (+27\\permil for hemicellulose; -155\\permil for n-alkanes). Nevertheless, minor dependencies of these

    2012-01-01

    When monitoring complex experiments, comparison is often made between regularly acquired histograms of data and reference histograms which represent the ideal state of the equipment. With the larger HEP experiments now ramping up, there is a need for automation of this task since the volume of comparisons could overwhelm human operators. However, the two-dimensional histogram comparison tools available in ROOT have been noted in the past to exhibit shortcomings. We discuss a newer comparison test for two-dimensional histograms, based on the Energy Test of Aslan and Zech, which provides more conclusive discrimination between histograms of data coming from different distributions than methods provided in a recent ROOT release.

    Full Text Available This study examines the factor structure and invariance of the instruments measuring burnout (Maslach Burnout Inventory - General Survey / MBI-GS and work engagement (Utrecht Work Engagement Scale / UWES in a sample of Dutch (N = 162 and Greek (N = 206 employees. Confirmatory factor analyses in both samples supported the superiority of the proposed three-factor structure of both the MBI-GS (exhaustion, cynicism, and reduced professional efficacy and the UWES (vigor, dedication, and absorption. Alternative two-factor and one-factor models did not show a better fit to the data. In addition, results of multigroup analyses partly supported the invariance of the three-factor model of the MBI-GS, and fully supported the invariance of the three-factor model of the UWES across the two national samples. These results suggest that the MBI-GS and the UWES are not only valid instruments for testing burnout and engagement but also allow comparisons across countries.

    The UK Health & Safety Executive's Management Standards Indicator Tool (MSIT) has been used to assess areas of work design, which may act as psychosocial hazards leading to burnout. These have not been assessed as predictors of employee engagement. To determine the utility of the MSIT in evaluating employee engagement as measured by the Utrecht Work Engagement Scale (UWES). A cross-sectional survey of employees from two sales organizations in London was performed using the MSIT and UWES. MSIT scores were analysed stratifying medium-high versus low engagement. Multivariate linear regression evaluated the association of all MSIT scores with UWES factors. Control, managerial support, peer support and employee role differed by engagement level. Demands, peer support and role exceeded MSIT benchmark guidance that would warrant urgent improvement. Role ambiguity was the only factor significantly associated with all subdomains of engagement. Role appears to play a major part in determining employee engagement. Assessment of the relationship between factors measured by the MSIT and UWES requires further investigation in wider organizational settings, particularly the influence of employee role on positive psychological outcomes. © The Author 2015.

Zech, Jr., visited the Soviet Union to initiate cooperative activities in civilian nuclear reactor safety between the two countries under their April 1988 Memorandum of Cooperation. Areas of future cooperation and a schedule of working group meetings to explore these areas were defined in a protocol signed during this visit. The delegation met with Soviet representatives in Moscow as the Joint coordinating Committee on Civilian Nuclear Reactor Safety. Additionally, while in Moscow, Chairman Zech held discussions with leaders and other senior officials of Soviet organizations with responsibility for nuclear power safety. Nuclear facilities were also visited, including the Kurchatov Institute of Atomic Energy (Moscow), the Novovoronezh Atomic Power Station, the Novovoronezh Training and Commissioning Center, the Izhora Heavy Equipment Production Plant (Kolpino), the V. G. Khlopin Radium Institute (Gatchina), the Chernobyl Atomic Power Station, the All-Union Center for Radiation Medicine (Kiev), and the Rovno Atomic Power Station. 35 figs

    Full Text Available O presente trabalho a partir das contribuições dos Estudos Culturais em Educação em sua vertente pós-estruturalista e dos Estudos desenvolvidos por Michel Foucault tem como objetivo problematizar a naturalização com que os afetos docentes vêm sendo descritos na cena educacional contemporânea e assumidos pelas professoras enquanto um atributo imanente ao profissional da educação. Desse modo, para realizar o intento proposto, a metodologia investigativa teve como inspiração, a pesquisa desenvolvida por Abramowski (2010, a respeito dos afetos docentes e as relações pedagógicas estabelecidas por professores dos anos iniciais de escolas Argentinas. Na esteira de tal pesquisa, foram realizadas vinte entrevistas semi estruturadas com docentes da Rede Pública de Ensino de Porto Alegre, tendo em vista conhecer as concepções de afeto das mesmas e as implicações de seus discursos com o trabalho pedagógico desenvolvido nas salas de aula em que atuavam. Através da análise do discurso de inspiração foucaultiana, foi possível perceber a operacionalização de certa ortopedia generificada dos afetos docentes, a recorrência de enunciados sustentados por saberes emergentes da psicologia das relações humanas, das pedagogias críticas e dos livros de auto-ajuda para professores que se disseminam no meio educacional brasileiro.

Esta relación ha sido muy pocas veces explorada, y menos aun en sujetos hispanos. Los participantes fueron trabajadores de tiendas comerciales en la zona central de Lima Metropolitana. Se halló que la deseabilidad social comparte varianza con los puntajes de agotamiento emocional e indiferencia, pero esta relación estuvo influenciada por el instrumento de medición de la deseabilidad social. Las correlaciones parciales entre los puntajes del mbi no fueron prácticamente diferentes de sus correlaciones de orden cero. El uwes no covarió con deseabilidad social.

    Full Text Available The objectives of this study were to validate two measures of affective well-being, namely the Maslach Burnout Inventory (MBI and the Utrecht Work Engagement Scale (UWES for employees in an insurance company, to assess their construct equivalence for different language groups and to determine the relationship between burnout and work engagement. A cross-sectional survey design with an availability sample (N = 613 was used. The MBI, UWES and a biographical questionnaire were administered. Structural equation modelling confirmed a three-factor model of burnout, consisting of Exhaustion, Cynicism and Professional Efficacy and a three-factor model of work engagement consisting of Vigour, Dedication and Absorption. Acceptable construct equivalence of the three-factor model of burnout and work engagement for different language groups was confirmed. A second-order factor analysis of the scales resulted in two factors, namely burnout and work engagement.

  7. The struggle with employee engagement: Measures and construct clarification using five samples.

    Among scholarly researchers, the Utrecht Work Engagement Scale (UWES) is a popular scale for assessing employee or work engagement. However, challenges to the scale's validity have raised major concerns about the measurement and conceptualization of engagement as a construct. Across 4 field samples, we examined 2 measures of engagement, the UWES and the Job Engagement Scale (JES), in both factor structure and patterns of relationships with theoretically hypothesized antecedents and consequences. In a fifth field sample, we examined the construct-level relationships between engagement and related variables, while controlling for sources of measurement error (i.e., item-specific factor, scale-specific factor, random response, and transient). By examining 2 measures, each derived from different theoretical bases, we provide unique insight into the measurement and construct of engagement. Our results show that, although correlated, the JES and UWES are not interchangeable. The UWES, more so than the JES, assesses engagement with overlap from other job attitudes, requiring improvement in the measurement of engagement. We offer guidance as to when to use each measure. Furthermore, by isolating the construct versus measurement of engagement relative to burnout, commitment, stress, and psychological meaningfulness and availability, we determined (a) the engagement construct is not the same as the opposite of burnout, warranting a reevaluation of the opposite-of-burnout conceptualization of engagement; and (b) psychological meaningfulness and engagement are highly correlated and likely reciprocally related, necessitating a modification to the self-role-expression conceptualization of engagement.

    Spatial analogue techniques consist in identifying locations whose recent-past climate is similar in some aspects to the future climate anticipated at a reference location. When identifying analogues, one key step is the quantification of the dissimilarity between two climates separated in time and space, which involves the choice of a metric. In this communication, spatial analogues and their usefulness are briefly discussed. Next, six metrics are presented (the standardized Euclidean distance, the Kolmogorov-Smirnov statistic, the nearest-neighbor distance, the Zech-Aslan energy statistic, the Friedman-Rafsky runs statistic and the Kullback-Leibler divergence), along with a set of criteria used for their assessment. The related case study involves the use of numerical simulations performed with the Canadian Regional Climate Model (CRCM-v4.2.3), from which three annual indicators (total precipitation, heating degree-days and cooling degree-days) are calculated over 30-year periods (1971-2000 and 2041-2070). Results indicate that the six metrics identify comparable analogue regions at a relatively large scale, but best analogues may differ substantially. For best analogues, it is also shown that the uncertainty stemming from the metric choice does generally not exceed that stemming from the simulation or model choice. A synthesis of the advantages and drawbacks of each metric is finally presented, in which the Zech-Aslan energy statistic stands out as the most recommended metric for analogue studies, whereas the Friedman-Rafsky runs statistic is the least recommended, based on this case study.

    Employee engagement is the emotional commitment of the employee towards the organisation. We aimed to analyse baseline work engagement using Utrecht Work Engagement Scale (UWES) at a teaching hospital. We have conducted a cross-sectional study within the National Health Service (NHS) Teaching Hospital in the UK. All participants were working age population from both genders directly employed by the hospital. UWES has three constituting dimensions of work engagement as vigor, dedication, and absorption. We conducted the study using UWES-9 tool. Outcome measures were mean score for each dimension of work engagement (vigor, dedication, absorption) and total score compared with control score from test manual. We found that the score for vigor and dedication is significantly lower than comparison group (Pengagement level is below average within the NHS employees. Vigor and dedication are significantly lower, these are characterised by energy, mental resilience, the willingness to invest one's effort, and persistence as well as a sense of significance, enthusiasm, inspiration, pride, and challenge. The NHS employees are immersed in work. Urgent need to explore strategies to improve work engagement as it is vital for improving productivity, safety and patient experience.

    Personal lifestyle, including diet, exercise, and sleep, might have an impact on work engagement, though previous studies have not focused on these relationships. The aim of this study was to examine whether dietary intake of fish, regular exercise, sufficient sleep, abstinence from alcohol, and abstinence from tobacco were positively associated with work engagement. We recruited adults aged 40-74 years who attended the health checkups with a particular focus on the metabolic syndrome in central Tokyo. In December 2015, 797 people responded to a questionnaire and 592 (74.3%) who had regular jobs were selected for this study. Work engagement was assessed on the 9-item Utrecht Work Engagement Scale (UWES-9). Bivariate and multivariate regression analyses were performed to examine the relationships between lifestyle and UWES-9. Dietary intake of fish, regular exercise, sufficient sleep, and abstinence from tobacco were significantly correlated with the total UWES-9 score, even after adjusting for age, sex, and depressive and anxiety symptoms. The results suggested a dose-response relationship between dietary fish intake and work engagement. Dietary fish intake, regular exercise, sufficient sleep, and abstinence from tobacco might be lifestyle factors that can serve as resources for work engagement. These findings could be useful in motivating employees to make lifestyle improvements and convincing employers and managers that lifestyle is important not only for health but also for productivity.

    Stress and anxiety are experienced by health care providers as a consequence of caregiving and may result in physical, emotional, and psychological outcomes that negatively impact work engagement. The purpose of this study was to determine whether auricular acupuncture can reduce provider anxiety and improve work engagement. Study participants received 5 auricular acupuncture sessions within a 16-week period utilizing the National Acupuncture Detoxification Association protocol for treating emotional trauma. Each participant completed the State-Trait Anxiety Inventory and the Utrecht Work Engagement Scale (UWES-9) prior to their first session and again after their fifth treatment. Significant reductions were found in state and trait anxiety (State-Trait Anxiety Inventory), as well as significant increases in the overall scores on the UWES as compared with baseline. Only the dedication subcategory of the UWES showed significant improvement. Engagement has been linked to increased productivity and well-being and improved patient and organizational outcomes. Providing effective strategies such as auricular acupuncture to support health care providers in reducing anxiety in the workplace may improve engagement.

    Research purpose: To (1 determine whether adapted versions of the Strengths Use and Deficit Improvement Questionnaire (SUDIQ and Utrecht Work Engagement Scale (UWES are valid and reliable, (2 determine the relationship of the SUDIQ dimensions in the nomological net, and (3 test a structural model. Motivation for the study: To gain a better understanding of the outcomes of following a balanced approach within a sport coaching context. Research design, approach and method: A cross-sectional research approach was used. An availability sample (N = 364 of teachers occupying roles as sport coaches from various schools across three provinces in South Africa was used. Structural equation modelling was used to test the factor structures and the structural model. Main findings: The results indicated a valid factor structure for the adapted SUDIQ and UWES. Relationships between the SUDIQ dimensions and job and personal resources were positive and significant. Individual strengths use was the strongest predictor of engagement. Individual deficit improvement and organisational strengths use were also significant predictors. Organisational deficit improvement did not significantly predict engagement. Practical/managerial implications: Evidence suggests the adapted SUDIQ and UWES can be utilised effectively in a sport coaching environment. Organisational strengths use is also important in managing engagement levels of sport coaches. Contribution/value-add: Valid and reliable measures were provided for use in a sport coaching environment. It substantiates the outcomes that can be gained by following a combined approach based on strength and deficit.

    This exploratory study aims to measure work engagement levels in psychiatry residents at three psychiatry residency programs using the Utrecht Work Engagement Scale (UWES). In addition, the study investigates the relationship between total engagement and its subscales, resident satisfaction, and a depression screen. Recruitment of 53/79 residents from three psychiatry residency programs in Illinois was completed. The residents were administered a questionnaire consisting of the UWES, the Primary Care Evaluation of Mental Disorders (Prime-MD) depression screen, and a residency satisfaction scale. Statistical analysis using independent samples t test and a one-way analysis of variance was used to assess differences on engagement total score and subscales and satisfaction scale. A logistic regression was used with the engagement subscales and the satisfaction scale as predictors of belonging to the depressed or non-depressed group. Psychiatry residents scored in the high range for total engagement and all its subscales except for vigor which was in the moderate range. Residents who screened positive for depression reported lower total engagement than those who were negative on the depression screen. Vigor was the only significant predictor (p = .004) of being in the depressed group after logistic regression. Total engagement and the subscale of dedication significantly predicted overall residency satisfaction (β = .473, p = .016). Higher total UWES-15 and its subscales of vigor and dedication are correlated with a lower rate of screening positive for depression and higher residency satisfaction. This exploratory study lends support for further study of this psychological construct in medical training programs, but replication is needed.

    To examine the relationships of two screening instruments recently developed for assessment of exhaustion disorder (ED) with some other well-known inventories intended to assess ED-related concepts and self-reports of job demands, job control, job support, private life stressors, and personality factors. A cross-sectional population sample ( n = 1355) completed: the Karolinska Exhaustion Disorder Scale (KEDS), Self-reported Exhaustion Disorder Scale (s-ED), Shirom-Melamed Burnout Questionnaire (SMBQ), Utrecht Work Engagement Scale (UWES-9), Job Content Questionnaire (JCQ), Big Five Inventory (BFI), and items concerning family-to-work interference and stress in private life. Compared to participants without any indication of ED, participants classified as having ED on KEDS or s-ED had higher scores on all four SMBQ subscales, lower scores on the UWES-9 subscales vigor and dedication, higher JCQ job demands scores, lower JCQ job support scores, higher degrees of family-to-work interference and stress in private life, and higher BFI neuroticism and openness scores. In addition, participants classified as having ED on KEDS had lower scores on the UWES-9 absorption subscale, the JCQ job control scale, and lower BFI extraversion, agreeableness and conscientiousness scores, compared to the subgroup not classified as having ED. As expected, we observed an overall pattern of associations between the ED screening inventories KEDS and s-ED and measures of burnout, work engagement, job demands-control-support, stress in private life, family-to-work interference, and personality factors. The results suggest that instruments designed to assess burnout, work engagement, and ED share common ground, despite their conceptual differences.

    Full Text Available Abstract Background To prevent early exit from work, it is important to study which factors contribute to healthy ageing. One concept that is assumed to be closely related to, and therefore may influence healthy ageing, is vitality. Vitality consists of both a mental and a physical component, and is characterised by a perceived high energy level, decreased feelings of fatigue, and feeling fit. Since VO2max gives an indication of one's aerobic fitness, which can be improved by increased levels of physical activity, and because feeling fit is one of the main characteristics of vitality, it is hypothesised that VO2max is related to vitality. Therefore, the aim of this study was to investigate the associations between VO2max and vitality. Methods In 427 older workers (aged 45 + years participating in the Vital@Work study, VO2max was estimated at baseline using the 2-km UKK walk test. Vitality was measured by both the UWES Vitality Scale and the RAND-36 Vitality Scale. Associations were analysed using linear regression analyses. Results The linear regression models, adjusted for age, showed a significant association between VO2max and vitality measured with the RAND-36 Vitality Scale (β = 0.446; 95% CI: 0.220-0.673. There was no significant association between VO2max and vitality measured with the UWES (β = -0.006; 95% CI:-0.017 - 0.006, after adjusting for age, gender and chronic disease status. Conclusions VO2max was associated with a general measure of vitality (measured with the RAND-36 Vitality Scale, but not with occupational health related vitality (measured with the UWES Vitality Scale. The idea that physical exercise can be used as an effective tool for improving vitality was supported in this study. Trial registration NTR1240

  19. Photovoltaic reciprocity and quasi-Fermi level splitting in nanostructure-based solar cells (Conference Presentation)

    Science.gov (United States)

    Aeberhard, Urs

    2017-04-01

    The photovoltaic reciprocity theory relates the electroluminescence spectrum of a solar cell under applied bias to the external photovoltaic quantum efficiency of the device as measured at short circuit conditions [1]. So far, the theory has been verified for a wide range of devices and material systems and forms the basis of a growing number of luminesecence imaging techniques used in the characterization of photovoltaic materials, cells and modules [2-5]. However, there are also some examples where the theory fails, such as in the case of amorphous silicon. In our contribution, we critically assess the assumptions made in the derivation of the theory and compare its predictions with rigorous formal relations as well as numerical computations in the framework of a comprehensive quantum-kinetic theory of photovoltaics [6] as applied to ultra-thin absorber architectures [7]. One of the main applications of the photovoltaic reciprocity relation is the determination of quasi-Fermi level splittings (QFLS) in solar cells from the measurement of luminescence. In nanostructure-based photovoltaic architectures, the determination of QFLS is challenging, but instrumental to assess the performance potential of the concepts. Here, we use our quasi-Fermi level-free theory to investigate existence and size of QFLS in quantum well and quantum dot solar cells. [1] Uwe Rau.

    Work-related musculoskeletal disorders (WRMD) are the result of the combination of different risk factors. They are very common among computer workers, mainly when neck and upper limbs are considered. Forty-two office workers from a public university participated in this study. They were divided into two groups: Symptomatic Subjects (SS, n=20) and Asymptomatic Subjects (AS, n=22), according to the Nordic Musculoskeletal Questionnaire (NMQ). Psychosocial indicators were assessed using the Job Content Questionnaire (JCQ) and Utrecht Work Engagement Scale (UWES). Workplaces were evaluated according to the Ergonomic Workplace Analysis (EWA), proposed by the Finnish Institute of Occupational Health. The NMQ showed higher weekly prevalence of complaints on neck, shoulders and wrist/hands (p=0.00) among SS. The annual prevalence of symptoms on wrist/hands was also higher among SS (p=0.02). The JCQ did not show any difference between groups (p>0.05). Higher proportion of servers with 'high level' of engagement, dedication and absorption, according to UWES, was identified among SS (p<0.01). EWA showed worse scores for 'Work Site', 'Job Content' and 'Repetitiveness of the Work' among SS (p<0.05). Servers are exposed to physical and psychosocial risk factors that can contribute to the development of WRMD. Work conditions need to be change in order to improve musculoskeletal health.

    Research on the prospective association of job demands and job resources with work engagement is still limited in Asian countries, such as Japan. The purpose of the present study was to investigate the prospective association of job demands (i.e., psychological demands and extrinsic effort) and job resources (i.e., decision latitude, supervisor support, co-worker support, and extrinsic reward), based on the job demands-control (JD-C) [or demand-control-support (DCS)] model and the effort-reward imbalance (ERI) model, with work engagement among Japanese employees. The participants included 423 males and 672 females from five branches of a manufacturing company in Japan. Self-administered questionnaires, including the Job Content Questionnaire (JCQ), the Effort-Reward Imbalance Questionnaire (ERIQ), the nine-item Utrecht Work Engagement Scale (UWES-9), and demographic characteristics, were administered at baseline (August 2009). At one-year follow-up (August 2010), the UWES-9 was used again to assess work engagement. Hierarchical multiple regression analyses were conducted. After adjusting for demographic characteristics and work engagement at baseline, higher psychological demands and decision latitude were positively and significantly associated with greater work engagement at follow-up (β = 0.054, p = 0.020 for psychological demands and β = 0.061, p = 0.020 for decision latitude). Having higher psychological demands and decision latitude may enhance work engagement among Japanese employees.

    This study explores work engagement in employed tumor-free cancer survivors (CSs) compared to matched controls from the general population (NORM). The sample consisted of 446 CSs tumor-free after primary treatment [226 females with breast cancer and 220 males (166 testicular cancer and 54 prostate cancer)] diagnosed 2-6 years prior to the study. All had returned to work and had favourable prognosis. NORM sample consisted of 588 employed controls (319 females, 269 males). All CSs and NORM filled in a mailed questionnaire covering demography, morbidity, and work-related issues including work engagement which was self-rated by the Utrecht Work Engagement Scale (UWES). No differences in work engagement were observed between the CSs and NORM measured by the UWES total scale score or by the Dedication and Absorption domain scores. The Vigor domains score was statistically lower among CSs (p = .03), but the effect size was only 0.19. The CSs reported significantly poorer work ability, poorer health status, greater numbers of disease symptoms, more anxiety, and reduced physical quality of life, and scored significantly higher on both neuroticism and extraversion. CONCLUSIONS/IMPLICATIONS FOR CSS: In spite of poorer health CSs who had returned to work after their treatment for breast, prostate, and testicular cancer showed similar work engagement as individuals without cancer. In such CSs employers have no reason to expect reduced work engagement. Future research should preferably have a prospective and comparative design.

    The possible associations of intragroup and intergroup conflict at work with psychological distress and work engagement were investigated in a cross-sectional study in a manufacturing factory in Japan. A self-administered questionnaire was sent to all employees, and 255 responses were returned (a response rate of 84%). Data from 247 workers (187 males and 60 females) with no missing values were analyzed. Intragroup and intergroup conflict at work, psychological distress, and work engagement were measured by the NIOSH-GJSQ, K6, and Utrecht Work Engagement Scale (UWES-9), respectively. An ANCOVA was conducted to compare K6 and UWES-9 scores among the tertiles on intragroup conflict or intergroup conflict scores, adjusting for demographic and occupational variables as well as worksite social support, separately for males and females. Intragroup conflict was associated with greater psychological distress for males (p for trend=0.009). Intergroup conflict was marginally significantly associated with psychological distress for both males and females (p for trend=0.050 and 0.051, respectively). Contrary to expectation, intergroup conflict was significantly associated with greater work engagement for females (p for trend=0.024). For males, intragroup and intergroup conflict at work may increase psychological distress; for females, intergroup conflict may increase both psychological distress and work engagement.

    The aim of this study was to evaluate musculoskeletal and psychosocial perception and compare these conditions regarding the type of job (white or blue-collar) and the type of management model (private or public). Forty-seven public white-collar (PuWC), 84 private white-collar (PrWC) and 83 blue-collar workers (PrBC) were evaluated. Job Content Questionnaire (JCQ) and Utrecht Work Engagement Scale (UWES) were applied to evaluate psychosocial factors. Nordic Musculoskeletal Questionnaire (NMQ) was used to assess musculoskeletal symptoms. Pressure Pain Threshold (PPT) was measured to evaluate sensory responses. According to JCQ, all groups were classified as active profile. There was a significant association between work engagement and workers' categories (p workers had the highest scores for all the UWES domains, while PrBC had the lowest ones. PPT showed that PrBC workers had an increased sensitivity for left deltoid (p workers had an increased sensitivity for both epicondyles than PuWC (right p  0.05). This study showed differences in psychosocial risk factors and musculoskeletal symptoms in workers engaged in different types of jobs and work organization. Personal and work-related characteristics, psychosocial factors and PPT responses were different across workers' group. Despite all, there was no significant difference in reported symptoms across the groups, possibly indicating that the physical load is similar among the sectors.

    Although attention has been paid to post-traumatic stress disorder (PTSD) among health care professionals after disasters, the impact of traumatic events on their work has not been elucidated. The aim of this study was to examine whether disaster-related distress, resilience, and post-traumatic growth (PTG) affect work engagement among health care professionals who had been deployed to the areas affected by the Great East Japan Earthquake that occurred on March 11, 2011. We recruited disaster medical assistance team members who were engaged in rescue activities after the earthquake. The short version of the Resilience Scale (RS-14) and Peritraumatic Distress Inventory (PDI) were administered one month after the earthquake, and the short form of Posttraumatic Growth Inventory (SF-PTGI) and Utrecht Work Engagement Scale (UWES) were administered four years after the earthquake. Work engagement is composed of vigor, dedication, and absorption. Regression analyses were used to examine the relationship of UWES with RS-14, PDI, and SF-PTGI. We obtained baseline data of 254 participants in April 2011, and 191 (75.2%) completed the follow-up assessment between December 2014 and March 2015. The results showed that RS-14 predicted vigor, dedication, and absorption; in addition, SF-PTGI was positively related with these three parameters (pwork engagement among health care professionals after disasters. These findings could be useful for establishing a support system after rescue activities during a large-scale disaster and for managing work-related stress among health care professionals.

    1998-08-01

    The present study utilizes the Israel Seismic Network (ISN) as a spatially distributed multichannel system for the discrimination of low-magnitude events (ML UWEs) and 16 earthquakes in the magnitude range ML = 1.6-2.8, within distances of 10-150 km, recorded by the ISN, were selected for the analysis. The analysis is based on a smoothed (0.5 Hz window) Fourier spectrum of the whole signal (defined by the signal-to-noise criterion), without picking separate wave phases. It was found that the classical discriminant of the seismic energy ratio between the relatively low-frequency (1-6 Hz) and high-frequency (6-11 Hz) bands, averaged over an ISN subnetwork, showed an overlap between UWEs and earthquakes and cannot itself provide reliable identification. We developed and tested a new multistation discriminant based on the low- frequency spectral modulation (LFSM) method. In our case the LFSM is associated with the bubbling effect in underwater explosions. The method demonstrates a distinct azimuth-invariant coherency of spectral shapes in the low-frequency range (1-12 Hz) of short-period seismometer systems. The coherency of the modulated spectra for different ISN stations was measured by semblance statistics commonly used in seismic prospecting for phase correlation in the time domain. The modified statistics provided an almost complete separation between earthquakes and underwater explosions.

    To develop, implement, and evaluate the effect of a faculty engagement and professional growth program targeted at junior faculty members. A faculty engagement and growth program based on adult learning theory was piloted in a clinical sciences department. Effect of the model was evaluated using a pre/post-survey evaluating faculty output and work engagement using the Utrecht Work Engagement Scale (UWES). Average number of publications/projects with cross-campus collaboration increased (0.58 versus 1.25, P = 0.03, 95%CI 0.059-1.264). Involvement in national/state organizations, number of accepted poster presentations, and grants submitted and/or funded all increased (p>0.05). Total UWES score increased (4.13 vs. 4.495 p = 0.21) with the greatest subscale increase in vigor (3.833 vs 4.347, P = 0.1). A faculty engagement and growth program targeting junior faculty members using adult learning theory as a framework may provide a novel and economic way for schools to support the development of these critical team members.

    A key requirement for underground nuclear astrophysics experiments is the very low background level in germanium detectors underground. The reference for these purposes is the world's so far only underground accelerator laboratory for nuclear astrophysics, LUNA. LUNA is located deep underground in the Gran Sasso laboratory in Italy, shielded from cosmic rays by 1400 m of rock. The background at LUNA was studied in detail using an escape-suppressed Clover-type HPGe detector. Exactly the same detector was subsequently transported to the Felsenkeller underground laboratory in Dresden, shielded by 45 m of rock, and the background was shown to be only a factor of three higher than at LUNA when comparing the escape-suppressed spectra, with interesting consequences for underground nuclear astrophysics. As the next step of a systematic study of the effects of a combination of active and passive shielding on the cosmic ray induced background, this detector is now being brought to the ''Reiche Zeche'' mine in Freiberg/Sachsen, shielded by 150 m of rock. The data from the Freiberg measurement are shown and discussed.

    In the project WAVE.O.R the potential of acoustic waves to enhance oil recovery was reviewed. The project focused on laboratory experiments of the oil displacement in sandstone cores under acoustic stimulation. Additionally, the Seismic Prediction While Drilling (SPWD) borehole device prototype was set up for a feasibility field test. The laboratory experiments showed that, depending on the stimulation frequency, acoustic stimulation allows for an enhanced oil recovery. For single frequency stimulation a mean increase of 3 % pore volumes was observed at distinguished frequencies. A cyclic stimulation, where two of these frequencies were combined, an increase of 5% pore volume was observed. The SPWD borehole device was tested and adjusted during feasibility tests in the GFZ underground laboratory in the research and education mine ''Reiche Zeche'' of the TU Bergakademie Freiberg and in the GFZ KTB-Deep Laboratory in Windischeschenbach. The first successful test of the device under realistic conditions was performed at the test site ''Piana di Toppo'' of the OGS Trieste, Italy.

    Full Text Available Formative evaluation should play a key role in the development of a science communication project or initiative. Such research is vital to understanding the needs and interests of the audience or participants; meeting these needs and interests helps ensure the project’s success. However, there can be a temptation to plough ahead without undertaking adequate formative evaluation. Using ScienceComics (www.sciencecomics.uwe.ac.uk as a case study, this article explores both the challenges and benefits of using formative evaluation to guide project development. It focuses on the actors involved in the formative stages and the impacts these actors had on the final outputs. This evidence is used to develop practical guidance on integrating formative evaluation right from the start.

  19. Sexing Berlin?

    Science.gov (United States)

    Dahlke, Birgit

    2011-01-01

    Berlin has always been a literary space of extremely diverse political and cultural projections. This essay investigates why after the unification of East and West Berlin the city has been imagined as a play zone of sexual self-fulfilment by authors such as Inka Parei, Tanja Dückers, Kathrin Röggla, Judith Hermann and Julia Franck. Have such erotic adventures replaced political vision in our post-utopian decade? What is the purpose of the laboured allegorisation of the fall of the wall in Durs Grünbein's essays or in the novels of Katja Lange-Müller and Thomas Hettche? The sexification of historical and political processes recalls similar stereotypes in the East German literature of the 1980s: the metropolis as a whore in works by Heiner Müller or Wolf Biermann, but also by younger authors of the independent literary scene in Berlin like Uwe Kolbe or Frank-Wolf Matthies.

    The core data reduction for the Nano-JASMINE mission is planned to be done with Gaia's Astrometric Global Iterative Solution (AGIS). The collaboration started at 2007 prompted by Uwe Lammers' proposal. In addition to similar design and operating principles of the two missions, this is possible thanks to the encapsulation of all Gaia-specific aspects of AGIS in a Parameter Database. Nano-JASMINE will be the test bench for Gaia AGIS software. We present this idea in detail and the necessary practical steps to make AGIS work with Nano-JASMINE data. We also show the key mission parameters, goals, and status of the data reduction for the Nano-JASMINE.

    Full Text Available The objective of this study was to investigate the work engagement of academics in selected South African higher education institutions as well as the impact of job demands and job resources on their work engagement. Stratified random samples (N = 471 were drawn from academic staff in three higher education institutions in South Africa. The Utrecht Work Engagement Scale (UWES and the Job Demands-Resources Scale (JDRS were administered. The results confirmed a two-factor structure of work engagement, consisting of vigour and dedication. Six reliable factors were extracted on the JDRS, namely organisational support, growth opportunities, social support, overload, advancement and job insecurity. Job resources (including organisational support and growth opportunities predicted 26% of the variance in vigour and 38% of the variance in dedication. Job demands (overload impacted on dedication of academics at low and moderate levels of organisational support.

    A recent development within burnout research is the shift to its conceptual opposite: work engagement. This study aimed to unravel the concepts of burnout and work engagement, and to determine their levels among dentists. A representative sample of 497 Dutch general dental practitioners was included (survey response rate of 59%), consisting of 372 men and 121 women (the gender of 4 dentists remained unknown). The hypothesized three-factor structure of work engagement (vigor, dedication, and absorption), as measured by the Utrecht Work Engagement Scale (UWES), was substantiated among dentists. It was also found that work engagement was related negatively to burnout, as measured by the Maslach Burnout Inventory (MBI). However, a model consisting of a reduced ('core') burnout factor and an 'enhanced' engagement factor (composed of the three original factors plus the burnout factor, personal accomplishment) showed the best fit. Overall burnout levels among dentists are low, and the levels of engagement indicate that dentists have a positive working attitude.

    The ethical debate about what is feasible culminates, for one side, in the indignant moral question whether man is allowed to do all he is able to do and, for the other side, in the very obligation to keep redefining the limits of creation, and to act accordingly. Consequently, the Young Generation, at their meeting in Gronau, Westphalia (about which we reported), discussed about ''High Technology - Responsible on Ethical and Moral Grounds?'' The paper presented to the participants by pastor Kai Uwe Schroeter reflects this dichotomy, but also takes a clear position in favor of the expansion of nuclear power. This issue of atw contains a revised version of the paper. It is published in the hope that it will furnish arguments for the philosophical and ethical debates about high technology. (orig.) [de

    These days physicians' work is characterized by an increase in economic demands, pressure and challenges in establishing a balance between work and family life. The current study investigates the relationship between physicians' job demands and resources, perceived job stress, work-family conflict, work engagement and job satisfaction. 564 clinicians specialising in different medical fields participated in the cross-sectional study. Self-administered questionnaires, including the COPSOQ and the UWES- Scale were administered. Our results illustrated significant relationships between physicians' work engagement and their job satisfaction as well as between job stress and work family conflict. Moreover, perceived job stress moderated the effect of high job demands on work family conflict. In addition, significant gender differences have been found in perceived stress levels, work family conflict and work engagement. This study proves and verified associations between work engagement, work-family conflict, job demands and resources that may influence employees' satisfaction. Implications for both working physicians and hospital management are given.

    2016-03-01

    Penta cameras consisting of a nadir and four inclined cameras are becoming more and more popular, having the advantage of imaging also facades in built up areas from four directions. Such system cameras require a boresight calibration of the geometric relation of the cameras to each other, but also a calibration of the sub-cameras. Based on data sets of the ISPRS/EuroSDR benchmark for multi platform photogrammetry the inner orientation of the used IGI Penta DigiCAM has been analyzed. The required image coordinates of the blocks Dortmund and Zeche Zollern have been determined by Pix4Dmapper and have been independently adjusted and analyzed by program system BLUH. With 4.1 million image points in 314 images respectively 3.9 million image points in 248 images a dense matching was provided by Pix4Dmapper. With up to 19 respectively 29 images per object point the images are well connected, nevertheless the high number of images per object point are concentrated to the block centres while the inclined images outside the block centre are satisfying but not very strongly connected. This leads to very high values for the Student test (T-test) of the finally used additional parameters or in other words, additional parameters are highly significant. The estimated radial symmetric distortion of the nadir sub-camera corresponds to the laboratory calibration of IGI, but there are still radial symmetric distortions also for the inclined cameras with a size exceeding 5μm even if mentioned as negligible based on the laboratory calibration. Radial and tangential effects of the image corners are limited but still available. Remarkable angular affine systematic image errors can be seen especially in the block Zeche Zollern. Such deformations are unusual for digital matrix cameras, but it can be caused by the correlation between inner and exterior orientation if only parallel flight lines are used. With exception of the angular affinity the systematic image errors for corresponding

    The aim of this study is to determine the level of engagement among dentists, and subsequently, to investigate which dental job resources are positively correlated with engagement. By stratifying on gender, age, and region, a representative sample of 848 general dental practitioners was drawn at random, plus an extra group of 95 female dentists for gender comparison purposes. Engagement was assessed using the Utrecht Work Engagement Scale (UWES), consisting of three subscales: Vigor, Dedication; and Absorption. Job resources were measured using the Dentists' Experienced Job Resources Scale (DEJRS). Six hundred and thirty two dentists (67%) responded, 76% male and 25% female. Mean age: 44.6 years (SD = 9.0). Engagement: Dedication and Absorption mean scores were higher among dentists when compared with manual norm scores, based upon a variety of professions, whereas Vigor mean scores were comparable to manual norm scores. Job resources:'Immediate results / Aesthetics' and '(Long term) Patient results' showed highest mean scores among all dentists. Gender differences were found on '(Long term) Patient results' and 'Patient care'. Engagement and job resources: All DEJRS subscales and the full scale showed statistically significant positive correlations (pmcc) with the UWES subscales. Dentists showed relatively high mean scores on an engagement measure when compared with manual norm scores. No gender differences in mean scores were found. Job resources most valued were 'Immediate results / Aesthetics'. The job resources, 'Idealism/Pride' and 'Patient care', showed most predictive value with regard to engagement among dentists. In order to prevent burnout, it is recommended to raise dentists' awareness of the importance to create sufficient time and space for stimulating aspects in their work.

    Primary healthcare professionals report high levels of distress and burnout. A new model of burnout has been developed to differentiate three clinical subtypes: 'frenetic', 'underchallenged' and 'worn-out'. The aim of this study was to confirm the validity and reliability of the burnout subtype model in Spanish primary healthcare professionals, and to assess the explanatory power of the self-compassion construct as a possible protective factor. The study employed a cross-sectional design. A sample of n = 440 Spanish primary healthcare professionals (214 general practitioners, 184 nurses, 42 medical residents) completed the Burnout Clinical Subtype Questionnaire (BCSQ-36), the Maslach Burnout Inventory General Survey (MBI-GS), the Self-Compassion Scale (SCS), the Utrecht Work Engagement Scale (UWES) and the Positive and Negative Affect Schedule (PANAS). The factor structure of the BCSQ-36 was estimated using confirmatory factor analysis (CFA) by the unweighted least squares method from polychoric correlations. Internal consistency (R) was assessed by squaring the correlation between the latent true variable and the observed variables. The relationships between the BCSQ-36 and the other constructs were analysed using Spearman's r and multiple linear regression models. The structure of the BCSQ-36 fit the data well, with adequate CFA indices for all the burnout subtypes. Reliability was adequate for all the scales and sub-scales (R≥0.75). Self-judgement was the self-compassion factor that explained the frenetic subtype (Beta = 0.36; pUWES and PANAS. The typological definition of burnout through the BCSQ-36 showed good structure and appropriate internal consistence in Spanish primary healthcare professionals. The negative self-compassion dimensions seem to play a relevant role in explaining the burnout profiles in this population, and they should be considered when designing specific treatments and interventions tailored to the specific vulnerability of each subtype.

    To investigate the psychological health--in particular, levels of burnout and engagement, job demands, job resources, and general psychological distress--among dental staff in Northern Ireland. Three hundred questionnaires were administered to all dental offices in the western part of Northern Ireland. The questionnaire consisted of 'Maslach Burnout Inventory (MBI)', 'Job Demands in Dentistry measure', 'Utrecht Work Engagement Scale (UWES)', 'Job Resources in dentistry measure', and 'General Health Questionnaire (GHQ)'. Overall response rate among all staff members was 45% (for general dental practitioners: 65%). Burnout mean scores were unfavourable when compared with MBI manual norm scores, 26% had scores in the 'high' categories of both emotional exhaustion (EE) and depersonalization (DP). This is an indication of severe burnout risk. Time pressure, financial worries, and difficult patients appeared to be the most prominent work demands (mean scores >3). All job demands' scales correlated significantly (P r UWES, and all job resources' subscales were all well above each subscale's range midpoint. Treatment results appeared the most prominent work resource. GHQ mean score for all was 1.05 (SD = 0.51). No difference in mean score was found between dentists and other staff (F(1,123) = 1.08, NS). With 'case level' set at a score >3 as a cut-off point, 25% of the subjects have to be considered cases. Burnout is a serious threat for the dental team in this region of Northern Ireland, especially among general dental practitioners. One-quarter of the dentists were categorized as having a serious burnout risk. Dentists appeared to have most trouble with the work environment aspects: time pressure and financial worries. Furthermore, the proportion of those suffering from psychological distress was unusually high. In contrast to these findings, encouraging levels of engagement were identified. It is recommended that attention for burnout risk is given priority by dental

    A worksite lifestyle intervention aiming to improve lifestyle behaviors could be an effective tool to keep older workers vital, and thereby prolong their labor participation. Therefore, this study evaluates the effectiveness of such an intervention on vitality, work engagement, productivity and sick leave. In a randomized controlled trial design, 367 workers (control group: N=363) received a 6-month intervention, which included two weekly guided group sessions: one yoga and one workout, as well as one weekly session of aerobic exercising, without face-to-face instruction, and three individual coach visits aimed at changing workers' lifestyle behavior by goal setting, feedback, and problem-solving strategies. Furthermore, free fruit was provided at the guided sessions. Data on work-related vitality (UWES vitality scale), general vitality (RAND-36 vitality scale), work engagement (UWES), productivity (single item scoring 0-10), and sick leave (yes/no past 3 months) were collected using questionnaires at baseline (N=730), and at 6- (N=575) and 12-months (N=500) follow-up. Effects were analyzed according to the intention-to-treat principle with complete cases (N=500) and imputed data (N=730). There were no significant differences in vitality, work engagement, productivity, and sick leave between the intervention and control group workers after either 6- and 12-months follow-up. Yoga and workout subgroup analyses showed a 12-month favorable effect on work-related vitality [β=0.14, 95% confidence interval (95% CI) 0.04-0.28] and general vitality (β=2.9, 95% CI 0.02-5.9) among high yoga compliers. For high workout compliers, this positive trend was also seen, but it was not statistically significant. Implementation of worksite yoga facilities could be a useful strategy to promote vitality-related work outcomes, but only if high compliance can be maximized. Therefore, impeding factors for participation should be investigated in more detail in future research.

    Full Text Available Aim: The aim of the study was to examine the differences in engagement and burnout syndrome in students of nursing/midwifery and psychology in Slovakia. Design: A cross-sectional design was used. Methods: 171 university students on a baccalaureate program participated in the research (90.9% females; age 20.6 ± 1.3; 80 psychology students, 91 nursing/midwifery students. The School Burnout Inventory (SBI and Utrecht Work Engagement Scale (UWES were employed as measurement methods. Results: A significant negative association between levels of burnout and engagement (R = 0.42; p < 0.01 was found. A linear regression model showed a significant effect of engagement on burnout (β = -0.34; 95% CI: -0.50; -0.19. However, the total explained variance was only 19.4%. Students of psychology scored higher in engagement compared to nursing and midwifery students (t = 6.89; p < 0.001. Conversely, midwifery and nursing students had higher levels of burnout compared to the group of psychology students (t = -4.55; p < 0,001. Conclusion: Nursing is considered to be a high risk profession in terms of development of burnout, which was demonstrated in this study by the higher burnout, and lower engagement levels in nursing and midwifery students. Higher attention to coping mechanisms for stress and burnout symptoms among students of healthcare professions is required in the school curriculum, especially in nursing programs.

    Care workers have an important social role which is set to expand with the increasing age of the UK population. However, the majority of care workers are employed on zero-hours contracts. Firstly, to investigate the relationship between working conditions and employee outcomes such as engagement and general mental well-being in a sample of UK care workers and management. Secondly, to assess whether the use of zero-hours contracts affects employee well-being. A cross-sectional survey of domiciliary care and care home employees, undertaken using the Management Standards Indicator Tool (MSIT), Utrecht Work Engagement Scale (UWES) and General Health Questionnaire (GHQ). T-tests and multivariate linear regression evaluated the differences in scoring between those with differing contractual conditions and job roles, and associations of MSIT scores with UWES and GHQ factors. Employee understanding of their role and job control were found to be priority areas for improvement in the sample. Similarly, care workers reported greater occupational demands and lower levels of control than management. However, while zero-hours contracts did not significantly influence employee well-being, these employees had greater levels of engagement in their jobs. Despite this, a greater proportion of individuals with zero-hours contracts had scores above accepted mental health cut-offs. Individual understanding of their role as care workers appears to play an important part in determining engagement and general mental well-being. However, more research is needed on the influence of zero-hours contracts on well-being, particularly in groups with increased likelihood of developing mental health disorders. © The Author 2017.

    This study aims to investigate burnout and study engagement among medical students at Sun Yat-sen University, China.A cross-sectional survey was conducted among undergraduate medical students of Sun Yat-sen University, China. A total of 453 undergraduate students completed a self-administered, structured questionnaire between January and February, 2016. Burnout and study engagement were measured using the Maslach Burnout Inventory-Student Survey (MBI-SS) and the UTRECHT Work Engagement Scale-Students (UWES-S), respectively. Subjects who scored high in emotional exhaustion subscale, high in cynicism subscale, and low in professional efficacy subscale simultaneously were graded as having high risk of burnout. Independent sample t tests and chi-square tests were used to compare the differences in burnout and work engagement between genders, majors, and grade levels.The means (standard deviations) of the MBI-SS subscales were 3.42 (1.45) for emotional exhaustion, 2.34 (1.64) for cynicism, and 3.04 (1.30) for professional efficacy. The means (standard deviations) of the UWES-S subscales were 3.13 (1.49) for vigor, 3.44 (1.47) for dedication and 3.00 (1.51) for absorption. Approximately 1 in 11 students experienced a high risk of burnout. There were no statistically significant gender differences in burnout and study engagement. There were also no statistically significant differences in burnout and study engagement subscales according to student major. Students in higher grades displayed increased burnout risk, higher mean burnout subscale score of cynicism, lower mean burnout subscale score of professional efficacy, and decreased mean study engagement subscale scores of dedication and absorption. There were strong correlations within study engagement subscales.Chinese medical students in this university experience a high level of burnout. Students at higher-grade level experience more burnout and decreased study engagement compared with students in lower level.

    In the modern urban water environment (UWE), engineered systems provide wastewater collection, treatment, and reuse; stormwater and graywater management; and potable water treatment, distribution and conservation. Underpinning such systems are physical, private and public, infrastructures whose integrities impinge on major goals of protecting groundwater and surface water resources, managing flooding, and securing safe drinking water. Here we study sanitary sewers, i.e. the main pipes in wastewater collection systems that improve public health by reducing pathogen exposure, and that afford reclaiming water for beneficial reuse. We ask: what is the relationship between sanitary sewer integrity and nearby water quality? Research methods include acquiring spatially defined sewer metadata that are analyzed using a published pipe leakage algorithm with variables of age, depth, materials of construction, length, diameter, slope, and nature of overburden. By executing the algorithm within a geographical information system (GIS), coupled with relating leakage probabilities to shallow groundwater table proximities—also digitally assembled, from well depth data—maps of wastewater exfiltration scores were produced for a city. Field sampling shallow groundwater allowed assessing concentrations of wastewater indicator compounds including personal care products and pharmaceuticals (PCPPs), and showing positive relationships between wastewater exfiltration scores and tryptophan-like fluorescence (TLF), reactive nitrogen species, an artificial sweetener acesulfame, and a stable isotope of oxygen (δ18O). The approach is extended to surface waters, where exfiltrating wastewater may transport from leaking sanitary sewers through the unsaturated zone to nearby storm drains or to storm drains that are submerged in contaminated groundwater. Spatially assessing sewer interactions within the UWE, as such, could aid urban infrastructure management and investment.

    Full Text Available Writing is an important experience through which we are able to share ideas, arouse feelings, persuade and convince other people (white & Arndt, 1991. It is important to view writing not solely as the product of an individual, but as a cognitive, social and cultural act. Writing is an act that takes place within a context, that accomplishes a particular purpose and that is appropriately shaped for its intended audience (Hamplyones & Condon, 1989. Here, the present research considers the significance effects of two important independent variables self-monitoring and peer-monitoring in writing activities on Iranian EFL learners. In this research it was supposed to study new effects of two Meta cognitive strategies self-monitoring and peer-monitoring on 173 male and female learners' writing activities whose age ranged between the age 16-27, and they had a composing description writing paragraph as pre & post test in the same conditions. Although many studies have been conducted on the effects of self-monitoring with a variety of students across a variety of settings (Amato-Zech, Hoff, & Doepke, 2006 Cooper et al., 2007, Dunlap, Dunlap, Koegel, & Koegel 1991. But goal of this study was to increase the participant’s on-task behavior in self & peer-monitoring (E. Johnson, 2007, Self &Peer-monitoring added. Although both of them were useful for providing challengeable students, and became useful for prosocial life, but self-monitoring helped them to become awareness of their weaknesses and strengths to increase positive way of the quality and quantity of their learning in written task, and peer-monitoring occurred when the students achieved recognition level to evaluate the other peers' behavior, and it was obviously understood that it needed more training time to arrive at the level of recognition of each others' behavior.

    Characteristics of dune-paleosol-sequences in Fuerteventura. - What should be questioned? Dominik Faust, TU Dresden, Germany Tobias Willkommen, TU Dresden, Germany Yurena Yanes, CSIC Granada/Cincinatti, Spain/USA David Richter, TU Dresden, Germany Ludwig Zöller, Uni Bayreuth, Germany The northern part of Fuerteventura is characterized by large dune fields. We investigated dune-paleosol-sequences in four pits to establish a robust stratigraphy and to propose a standard section. An interaction of processes like dune formation, soil formation and redeposition of soils and sand are most important to understand the principles of landscape development in the study area. To our mind a process cycle seem to be important: First climbing-dunes are formed by sand of shelf origin. Then soil formation could have taken place. Soil and/or sand were then eroded and deposited at toe slope position. This material in turn is the source of new sand supply and dune formation. The described cycle may be repeated several times and this ping-pong-process holds on. The results are sections composed of dune layers, paleosols and colluvial material interbedded. Fundamental questions still remain unanswered: Is climate change responsable for changes in process combination (e.g. from dune formation to soil formation)? Or are these features due to divergence phenomenon, where different effects/results (dune and soils) may be linked to similar causes (here: climate)? Assuming that different features (soils and dunes) were formed under one climate, increasing soil forming intensity could be mainly a function of decreasing sand supply. This in turn could be caused by reduced sand production (s. ZECH et al. accepted). However geochemical data and mollusc assemblages point to changing environments in space and even climate modifications in time.

    Full Text Available Laser beam machining (LBM is a promising and high accuracy machining technology in advanced manufacturing process. In LBM, crucial machining qualities of the end product include heat affected zone, surface roughness, kerf width, thermal stress, taper angle etc. It is essential for industrial applications especially in laser cutting of thermoplastics to acquire output product with minimum kerf width. The kerf width is dependent on laser input parameters such as laser power, cutting speed, standoff distance, assist gas pressure etc. However it is difficult to get a functional relationship due to the high uncertainty among these parameters. Hence, total 81 sets of full factorial experiment were conducted, representing four input parameters with three different levels. The experiments were performed by a continuous wave (CW CO2 laser with the mode structure of TEM01 named Zech laser machine that can provide maximum laser power up to 500 W. The polymethylmethacrylate (PMMA sheet with thickness of 3.0 mm was used for this experiment. Laser power, cutting speed, standoff distance and assist gas pressure were used as input parameters for the output named kerf width. Standoff distance, laser power, cutting speed and assist gas pressure have the dominant effect on kerf width, respectively, although assist gas has some significant effect to remove the harmful gas. ANFIS model has been developed for online control purposes. This research is considered important and helpful for manufacturing engineers in adjusting and decision making of the process parameters in laser manufacturing industry of PMMA thermoplastics with desired minimum kerf width as well as intricate shape design purposes.

    The aims of this study were to analyse whether dentists offer or recommend complementary and alternative medicine (CAM) remedies in their clinical routine, and how effective these are rated by proponents and opponents. A second aim of this study was to give a profile of the dentists endorsing CAM. A prospective, explorative, anonymised cross-sectional survey was spread among practicing dentists in Germany via congresses, dental periodicals and online (n=250, 55% male, 45% female; mean age 49.1±11.4years). Of a set of 31 predefined CAM modalities, the dentists integrated plant extracts from Arnica montana (64%), chamomile (64%), clove (63%), Salvia officinalis (54%), but also relaxation therapies (62%), homeopathy (57%), osteopathic medicine (50%) and dietetics (50%). The effectiveness of specific treatments was rated significantly higher (peffective, namely ear acupuncture, osteopathic medicine and clove. For ear acupuncture these scores did not significantly differ between both groups. With respect to the characteristic of the proponents, the majority of CAM endorsing dentists were women. The mean age (50.4±0.9 vs 47.0±0.9years) and number of years of professional experience (24.2±1.0 vs 20.0±1.0years) were significantly higher for CAM proponents than the means for opponents (p<0.0001 respectively). CAM proponents worked significantly less (p<0.0001) and their perceived workload was significantly lower (p=0.008). Their self-efficacy expectation (SEE) and work engagement (Utrecht work engagement, UWE) were significantly higher (p≤0.01 and p<0.0001) compared to dentists who abandoned these treatment options. The logistic regression model showed (exploratively) an increased association from CAM proponents with the UWES subscale dedication, with years of experience, and that men are less likely to be CAM proponents than women. Various CAM treatments are recommended by German dentists and requested by their patients, but the scientific evidence for these

    Quality improvement (QI) Programmes, like the Productive Ward: Releasing-time-to-care initiative, aim to 'engage' and 'empower' ward teams to actively participate, innovate and lead quality improvement at the front line. However, little is known about the relationship and impact that QI work has on the 'engagement' of the clinical teams who participate and vice-versa. This paper explores and examines the impact of a large-scale QI programme, the Productive Ward, on the 'work engagement' of the nurses and ward teams involved. Using the Utrecht Work Engagement Scale (UWES), we surveyed, measured and analysed work engagement in a representative test group of hospital-based ward teams who had recently commenced the latest phase of the national 'Productive Ward' initiative in Ireland and compared them to a control group of similar size and matched (as far as is possible) on variables such as ward size, employment grade and clinical specialty area. 338 individual datasets were recorded, n=180 (53.6%) from the Productive Ward group, and n=158 (46.4%) from the control group; the overall response rate was 67%, and did not differ significantly between the Productive Ward and control groups. The work engagement mean score (±standard deviation) in the Productive group was 4.33(±0.88), and 4.07(±1.06) in the control group, representing a modest but statistically significant between-group difference (p=0.013, independent samples t-test). Similarly modest differences were observed in all three dimensions of the work engagement construct. Employment grade and the clinical specialty area were also significantly related to the work engagement score (pengagement (the vigour, absorption and dedication) of ward-based teams. The use and suitability of the UWES as an appropriate measure of 'engagement' in QI interventions was confirmed. The engagement of nurses and front-line clinical teams is a major component of creating, developing and sustaining a culture of improvement. Copyright

    Full Text Available Primary healthcare professionals report high levels of distress and burnout. A new model of burnout has been developed to differentiate three clinical subtypes: 'frenetic', 'underchallenged' and 'worn-out'. The aim of this study was to confirm the validity and reliability of the burnout subtype model in Spanish primary healthcare professionals, and to assess the explanatory power of the self-compassion construct as a possible protective factor.The study employed a cross-sectional design. A sample of n = 440 Spanish primary healthcare professionals (214 general practitioners, 184 nurses, 42 medical residents completed the Burnout Clinical Subtype Questionnaire (BCSQ-36, the Maslach Burnout Inventory General Survey (MBI-GS, the Self-Compassion Scale (SCS, the Utrecht Work Engagement Scale (UWES and the Positive and Negative Affect Schedule (PANAS. The factor structure of the BCSQ-36 was estimated using confirmatory factor analysis (CFA by the unweighted least squares method from polychoric correlations. Internal consistency (R was assessed by squaring the correlation between the latent true variable and the observed variables. The relationships between the BCSQ-36 and the other constructs were analysed using Spearman's r and multiple linear regression models.The structure of the BCSQ-36 fit the data well, with adequate CFA indices for all the burnout subtypes. Reliability was adequate for all the scales and sub-scales (R≥0.75. Self-judgement was the self-compassion factor that explained the frenetic subtype (Beta = 0.36; p<0.001; isolation explained the underchallenged (Beta = 0.16; p = 0.010; and over-identification the worn-out (Beta = 0.25; p = 0.001. Other significant associations were observed between the different burnout subtypes and the dimensions of the MBI-GS, UWES and PANAS.The typological definition of burnout through the BCSQ-36 showed good structure and appropriate internal consistence in Spanish primary healthcare professionals

    Ice masses on the Western range of the Central Andes are a main source of water resources and act as a geoindicator of variations in the climate of the tropics (Mark, 2008). The study of their evolution is of particular interest since they are situated in the transition zone between the tropical and mid-latitude circulation areas of the atmosphere (Zech et al., 2007). The function of this transition area is currently under debate, and understanding it is essential for the development of global climate models (Kull et al, 2008; Mark, 2008). However our understanding of the evolution of glaciers and their paleoclimatic factors for this sector of the Central Andes is still at a very basic level. This paper presents initial results of a study on the glacial evolution of the Ampato volcanic complex (15°24´- 15° 51´ S, 71° 51´ - 73° W; 6288 m a.s.l.) located in the Western Range of the Central Andes in Southern Peru, 70 km NW of the city of Arequipa. The main objectives are to identify the number of glacial phases the complex has undergone using geomorphological criteria to define a time frame for each phase, based on cosmogenic 36Cl dating of a sequence of moraine deposits; and to estimate the glacier Equilibrium Line Altitude (ELA) of each phase. The Ampato volcanic complex is formed by 3 great andesitic stratovolcanoes, the Nevados HualcaHualca-Sabancaya-Ampato, which started forming between the late Miocene and early Quaternary (Bulmer et al., 1999), aligned N-S and with summits covered with glaciers. The Sabancaya volcano is fully active, with its latest eruption occurring in 2001. Glacial landforms were identified and mapped using photointerpretation of vertical aerial photographs from 1955 (1:35,000 scale, National Geographic Institute of Peru), oblique photographs from 1943 (Aerophotographical Service of Peru), and a geo-referenced high-resolution Mrsid satellite image from 2000 (NASA). This cartography was corrected and improved through fieldwork. It was

    Job crafting, an employee-initiated job design/redesign, has become important for employees' well-being. However, most studies on the relationship between job crafting and employees' well-being have been conducted in western countries; thus, it is unclear whether job crafting can be effectively applied to Asian cultures, such as Japan, which emphasizes group harmony. The aim of this study was to examine the cross-sectional associations of self-reported job crafting with work engagement and psychological distress among employees in Japan. A questionnaire survey through the internet was conducted among all employees of a manufacturing company in Japan. We analyzed the data from 894 respondents, all employees with regular employment. Job crafting, work engagement, and psychological distress were assessed using the Japanese version of the Job Crafting Questionnaire, the Japanese version of the Utrecht Work Engagement Scale (UWES), and the Brief Job Stress Questionnaire (BJSQ), respectively. Hierarchical multiple regression showed that increasing structural job resources, social job resources, and challenging job demands was significantly and positively associated with work engagement ( β  = 0.31, p  engagement and lower psychological distress. In addition, increasing social job resources and challenging job demands are also associated with higher work engagement.

The findings indicated that PA was directly and indirectly associated with SE. BMI predicted SE neither directly nor indirectly, but was directly associated with PPF and both directly and indirectly with BI. Furthermore, PPF was directly related to BI and SE, and a direct association was found between BI and SE. The pattern of results suggests that among a sample of adults, PA is directly and indirectly associated with SE, PPF, and BI, but not with BMI. PA, PPF, and BI appear to play an important role in SE. Accordingly, regular PA should be promoted, in particular, among adults reporting lower SE. Keywords: physical activity, self-esteem, physical fitness, body image, adults

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

    To examine the differences in work engagement among nurses in Saudi Arabia and its relationship with personal characteristics across different hospital affiliations. Quality care requires an adequate supply of engaged nurses who are dedicated, energised and absorbed in their work. In the nursing profession, work engagement is of considerable importance, owing to the shortage of nurses and the continuing reduction in healthcare costs. An analytic comparative cross-sectional design was used. Eight hospitals from three provinces and different affiliation types participated in the study. The Utrecht work engagement scale (UWES) was used to measure 980 nurses' work engagement. The findings indicate that nurses' total engagement scores were closer to the higher end of the Likert scale. The findings indicate generally high levels of work engagement, particularly regarding the element of dedication. Furthermore, the study shows significant differences in nurses' engagement among the various work settings and in nurses' age and experience. A number of nurses' personal characteristics have independent influences on their work engagement. Nurse leaders should acknowledge that a statement of professional nursing scope of practice is a necessity to encourage and fulfil engagement. © 2016 John Wiley & Sons Ltd.

    Summary Low work engagement may contribute towards decreased well‐being and work performance. Evaluating, boosting and sustaining work engagement are therefore of interest to many organisations. However, the evidence on which to base interventions has not yet been synthesised. A systematic review with meta‐analysis was conducted to assess the evidence for the effectiveness of work engagement interventions. A systematic literature search identified controlled workplace interventions employing a validated measure of work engagement. Most used the Utrecht Work Engagement Scale (UWES). Studies containing the relevant quantitative data underwent random‐effects meta‐analyses. Results were assessed for homogeneity, systematic sampling error, publication bias and quality. Twenty studies met the inclusion criteria and were categorised into four types of interventions: (i) personal resource building; (ii) job resource building; (iii) leadership training; and (iv) health promotion. The overall effect on work engagement was small, but positive, k = 14, Hedges g = 0.29, 95%‐CI = 0.12–0.46. Moderator analyses revealed a significant result for intervention style, with a medium to large effect for group interventions. Heterogeneity between the studies was high, and the success of implementation varied. More studies are needed, and researchers are encouraged to collaborate closely with organisations to design interventions appropriate to individual contexts and settings, and include evaluations of intervention implementation. © 2016 The Authors.

    Research purpose: The main purpose of the study was to investigate whether work-based identity and work engagement differed (in combination with personal alienation, helping behaviour and burnout as potential antecedents (amongst numerous others of task performance and turnover intention. Research design: A census-based sampling approach amongst 23 134 employees in the employment of an ICT company yielded a sample of 2429 usable questionnaires. Scales used in the study were the Maslach Burnout Inventory (MBI-HSS-20, Utrecht Work Engagement Scale (UWES, Work-based Identity, Personal Alienation, Helping Behaviour, Turnover Intention and Task Performance Scales. Main findings: The findings indicate that work-based identity and work engagement give similar appearing results as potential predictors of turnover intention and task performance. Practical/managerial implications: Reducing withdrawal behaviours and enhancing work performance are everyday challenges for organisations. Interventions focused on enhancing work-based identity and work engagement in the work environment should have a meaningful impact when these behaviours need to be addressed. Contribution/value-add: Work-based identity as a multidimensional construct has the potential, with further refinement, to become a valuable construct that can play a leading role in future work engagement research.

    Lowered work engagement and burnout are a growing problem in recent years, especially among physicians. Cynicism, lack of energy and decreased efficacy may lead to the occurrence of severe depression. These phenomena influence almost every aspect of affected person's life, both professional and extraprofessional, and decrease its quality. The aim of our study was to evaluate the influence of family life and other factors on levels of work engagement and risk of depression. Our study was conducted on a group of 417 physicians from Poland, Serbia and Bulgaria using a paper questionnaire. The collected data was subjected to statistical analyses using Statsoft Statistica v. 10.0 software. There was no significant correlation between work engagement and sex or age. The highest score on work engagement was in Serbia (m=4.41; Mann-Whitney's U test with pUWES and SWING scales. WHI+/WHI- ratio correlates significantly with a BDI scale (Spearman's r=-0.49; pengagement and risk of burnout. The negative influence of work on family life may increase the risk of depression, and that effect is not susceptible to either positive or negative interactions of family life with work. The country with the lowest expenditure on a healthcare have also the lowest levels of work engagement.

    Work engagement has been conceptualized as a relatively stable phenomenon, partly explained by the presence of specific job and organizational characteristics. Work engagement is important to the dental workforce worldwide, and the lack of it has been known to cause burnout. Positivity among dentists is essential as it is directly proportional to the patient's satisfaction towards the dental care. To assess work engagement among dentists in the city of Hyderabad, India. A cross-sectional questionnaire study was conducted to assess work engagement among dentists enrolled with the local branch of the Indian Dental Association in the city of Hyderabad, India. The shortened form of the Utrecht Work Engagement Scale (UWES-9) questionnaire was employed for the assessment. The mean scores of total work engagement and its domains based on gender and educational qualifications were estimated using Student t- test. A total of 371 subjects participated in the study. Females reported higher mean scores than males for total work (p = 0.40) and its dimensions (Vigor; p = 0.23, Dedication; p = 0.53, Absorption; p = 0.69). Dentists with Master's degree had higher mean scores not only in the total work, but also in its dimensions. (p = 0.01). The present study reported that females had higher mean scores of total work engagement and its individual domains. In comparison with a Bachelor's degree, having a Master's degree enhanced work engagement among dentists in Hyderabad, India.

    To present validity data for the Work Experience Measurement Scale (WEMS), an instrument measuring multifaceted work experience from a salutogenic health resource perspective as a contrast to the more common pathogenic risk perspective, by exploring WEMS relationship to established measurements that are positively related to health and work. A salutogenic perspective focuses on finding conditions and resources in life, for example at work, that can enhance the individual's health and strength, instead of those causing illness and weakness. This study was carried out in 2009 at a Swedish hospital with a web-based survey (WEMS) to 770 employees. Different occupational groups at the hospital participated. Additional questionnaires used at the same time were the Utrecht Work Engagement Scale (UWES-9), the Salutogenic Health Indicator Scale (SHIS), the General Self-Efficacy scale (GSE), and three questions about self-rated health, general well-being, and quality of life. Cronbach's Alpha of WEMS sub-indices were in the interval of 0.85-0.96. Convergent validity and discriminant validity of WEMS and its sub-indices were shown to be satisfying by correlations. In addition, WEMS demonstrated the ability to discriminate between groups. WEMS sub-indices discriminated even better between groups than the total index. The WEMS proved to be a workplace health promotion questionnaire that was able to measure experiences of work from a salutogenic perspective. The WEMS has a potential of being a useful tool in workplace health promotion to enhance positive human capabilities and resources to improve work performance.

    To determine the levels of burnout and work engagement among dentists in the United Kingdom.Study design Postal survey of 500 dentists selected at random from the General Dental Council register. Respondents completed a questionnaire pack comprising the Utrecht Work Engagement Scale (UWES-17) and the Maslach Burnout Inventory-Human Services Survey (MBI-HSS), together with questions on demographic characteristics. Approximately 8% of respondents had scores suggestive of burnout on all three scales of the MBI-HSS and a further 18.5% had high scores in two of the domains. Eighty-three percent of respondents had work engagement scores suggestive of moderate or high work engagement. Dentists with postgraduate qualifications and those who work in larger teams had lower burnout scores and more positive work engagement scores. Dentists who spend a greater proportion of their time in NHS practice showed lower work engagement and higher levels of burnout. Burnout affects a small but significant proportion of dental practitioners in the United Kingdom. A larger proportion of practitioners show low work engagement, suggesting a negative attitude to their work. Higher burnout scores and lower work engagement scores were found in dentists without postgraduate qualifications, those in small teams and in those who spend a greater proportion of their time in NHS practice.

    With the globalization of occupational health psychology, more and more researchers are interested in applying employee well-being like work engagement (i.e., a positive, fulfilling, work-related state of mind that is characterized by vigor, dedication, and absorption) to diverse populations. Accurate measurement contributes to our further understanding and to the generalizability of the concept of work engagement across different cultures. The present study investigated the measurement accuracy of the Japanese and the original Dutch versions of the Utrecht Work Engagement Scale (9-item version, UWES-9) and the comparability of this scale between both countries. Item Response Theory (IRT) was applied to the data from Japan (N = 2,339) and the Netherlands (N = 13,406). Reliability of the scale was evaluated at various levels of the latent trait (i.e., work engagement) based the test information function (TIF) and the standard error of measurement (SEM). The Japanese version had difficulty in differentiating respondents with extremely low work engagement, whereas the original Dutch version had difficulty in differentiating respondents with high work engagement. The measurement accuracy of both versions was not similar. Suppression of positive affect among Japanese people and self-enhancement (the general sensitivity to positive self-relevant information) among Dutch people may have caused decreased measurement accuracy. Hence, we should be cautious when interpreting low engagement scores among Japanese as well as high engagement scores among western employees.

    To correlate workgroup engagement in nursing teams and the clinical learning experience of nursing students. Work engagement plays a pivotal role in explaining motivational dynamics. Nursing education is workplace-based and, through their clinical placements, nursing students develop both their clinical competences and their professional identity. However, there is currently a lack of evidence on the role of work engagement related to students' learning experiences. A total of 519 nurses and 519 nursing students were enrolled in hospital settings. The Utrecht Work Engagement Scale (UWES) was used to assess work engagement, and the Clinical Learning Environment and Supervision plus nurse Teacher (CLES+T) scale was used to assess students' learning experience. A multilevel linear regression analysis was performed. Group-level work engagement of nurses correlated with students' clinical learning experience (β = 0.11, P learning (respectively, β = 0.37, P education. Nursing education institutions and health-care settings need to conjointly work to build effective organisational climates. The results highlighted the importance of considering the group-level analysis to understand the most effective strategies of intervention for both organisations and nursing education. © 2015 John Wiley & Sons Ltd.

    2009-10-01

    The aim of the present study is to demonstrate the empirical distinctiveness of workaholism and work engagement by examining their relationships with well-being in a sample of 776 Japanese employees. We expected that workaholism is associated with unwell-being (i.e., high psychological distress and physical complaints, low job and family satisfaction, and low job performance), whereas work engagement is associated with well-being. Well-validated questionnaires were used to measure workaholism (DUWAS), work engagement (UWES), and well-being (BJSQ, HPQ). Structural Equation Modeling showed that, as expected, workaholism was positively associated with ill-health (i.e., psychological distress and physical complaints) and negatively associated with life satisfaction (i.e., job and family satisfaction) and job performance. In contrast, work engagement was negatively associated with ill-health and positively associated with life satisfaction and job performance. These findings suggest that workaholism and work engagement are two different kinds of concepts, which are negatively and positively related to various indicators of well-being, respectively.

    During the recent decades Brazil has experienced an exponential growth in the aviation sector resulting in an increasing workforce. The aircraft maintenance industry stands out, where the workers have to handle different kind of objects. The aim of this study was to evaluate psychosocial indicators as well as musculoskeletal symptoms and disorders among aircraft maintenance workers. One hundred and one employees were evaluated (32.69 ± 8.25 yr, 79.8 ± 13.4 kg, and 1.75 ± 0.07 m). Musculoskeletal symptoms and disorders were assessed through the Nordic Musculoskeletal Questionnaire (NMQ) and a standardized physical examination. The Job Content Questionnaire (JCQ) and the Utrecht Work Engagement Scale (UWES) were applied to evaluate psychosocial indicators. Results of the NMQ indicate the lower back as the most affected body region. On the other hand, the physical examination has shown clinical diagnosis of shoulder disorders. Neck, upper back and ankle/foot were also reported as painful sites. Most of workers have active work-demand profile and high work engagement levels. We suggest that musculoskeletal symptoms may be related to high biomechanical demand of the tasks performed by workers, what must be further investigated.

    Motivation for the study: The study on the role of ethical leadership practices on employee engagement was motivated by the need to create an engaged workforce and a trusting work environment. Research approach, design and method: Data was collected using an electronic web-based questionnaire comprising three scales, namely the Utrecht Work Engagement Scale (UWES,Leader Trust Scale (LTS and the Leadership of Ethics Scale (LES. In total, 204 completed questionnaires were returned. Data was analysed by means of item and confirmatory factor analysis conducted via structural equation modelling (SEM. Main findings: High levels of reliability were found for all the measurement scales used. The results from the structural equation modelling (SEM indicated positive relationships between trust in the leader and work engagement, between ethical leadership and work engagement and between ethical leadership and trust in the leader. Practical/managerial implications: The findings emphasise the role played by ethical leadership behaviour of managers in promoting work engagement through the creation of employee relationships anchored on trust. Future studies should develop the theoretical model further by identifying other variables that influence work engagement. Contribution/value-add: Organisations today still face the challenge of developing an effective strategy for achieving work engagement. The ethical leadership style of managers is likely to create an ethical and trusting work climate conducive to the work engagement of employees.This is likely to enhance productivity as well as employee creativity and innovation.

    Research purpose: The main aim of this study was to conceptualise and investigate the causal relationship and temporal order in the relationship between PsyCap and engagement by means of longitudinal data. Motivation for the study: The rationale for establishing the sequence of engagement and psychological capital lies in the fact that training interventions to enhance the organisational well-being of employees may need to be focused on either one or the other. Research design, approach and method: A longitudinal study with a cross-lagged panel design was conducted; data was gathered by means of a survey that was constructed for the purpose of the study. The survey contained the Utrecht Work Engagement Scale (UWES, and a measure of PsyCap. All employees within a chemical factory (N = 1003 were approached to provide data; 163 employees participated. Main findings: Results revealed that PsyCap at Time 1 (T1 did not significantly predict engagement at Time 2 (T2. Evidence does however exist that initial levels of employee engagement predict subsequent PsyCap. Practical/managerial implications: Results suggest that employee interventions aimed at protecting and fostering employee engagement may have implications for subsequent employee psychological capital. Contribution/value-add: As an empirical, longitudinal study to address the temporal order between PsyCap and work engagement, this study makes a contribution especially to theory, but also with practical implications by indicating that engagement precedes employee psychological capital.

    Full Text Available Abstract With the globalization of occupational health psychology, more and more researchers are interested in applying employee well-being like work engagement (i.e., a positive, fulfilling, work-related state of mind that is characterized by vigor, dedication, and absorption to diverse populations. Accurate measurement contributes to our further understanding and to the generalizability of the concept of work engagement across different cultures. The present study investigated the measurement accuracy of the Japanese and the original Dutch versions of the Utrecht Work Engagement Scale (9-item version, UWES-9 and the comparability of this scale between both countries. Item Response Theory (IRT was applied to the data from Japan (N = 2,339 and the Netherlands (N = 13,406. Reliability of the scale was evaluated at various levels of the latent trait (i.e., work engagement based the test information function (TIF and the standard error of measurement (SEM. The Japanese version had difficulty in differentiating respondents with extremely low work engagement, whereas the original Dutch version had difficulty in differentiating respondents with high work engagement. The measurement accuracy of both versions was not similar. Suppression of positive affect among Japanese people and self-enhancement (the general sensitivity to positive self-relevant information among Dutch people may have caused decreased measurement accuracy. Hence, we should be cautious when interpreting low engagement scores among Japanese as well as high engagement scores among western employees.

    Increased globalisation of the ornamental stone market has lead to increased competition and more rigorous product quality requirements. As such, there are strong motivators to introduce new, more effective, inspection technologies that will help enable stone processors to reduce costs, improve quality and improve productivity. Natural stone surfaces may contain a mixture of complex two-dimensional (2D) patterns and three-dimensional (3D) features. The challenge in terms of automated inspection is to develop systems able to reliably identify 3D topographic defects, either naturally occurring or resulting from polishing, in the presence of concomitant complex 2D stochastic colour patterns. The resulting real-time analysis of the defects may be used in adaptive process control, in order to avoid the wasteful production of defective product. An innovative approach, using structured light and based upon an adaptation of the photometric stereo method, has been pioneered and developed at UWE to isolate and characterize mixed 2D and 3D surface features. The method is able to undertake tasks considered beyond the capabilities of existing surface inspection techniques. The approach has been successfully applied to real stone samples, and a selection of experimental results is presented.

    Research purpose: The objective of this study was to investigate the relationship between coping strategies and work engagement in three occupational groups in South Africa. Motivation for the study: There is little understanding of the relationship between effective forms of coping and positive outcomes (like work engagement. Research design, approach and method: The researchers used a survey design. They drew random and stratified samples (N = 3178 from three occupational groups. These were technical employees in an electricity provider, professional and enrolled nurses and police officers. They administered the Coping Orientations to the Problems Experienced (COPE and the Utrecht Work Engagement Scale (UWES. Main findings: The results showed that there was a statistically significant relationship between work engagement, problem-focused coping, positive reinterpretation and growth. In the nursing sample, high problem-focused coping, low avoidance and low ventilation of emotions predicted work engagement best. In the police sample, four coping strategies (problem-focused coping, seeking social support, turning to religion and low ventilation of emotions predicted work engagement best. In the technician sample, problem-focused coping and low ventilation of emotions predicted work engagement best. Practical/managerial implications: Organisations should consider employees’ coping strategies when they introduce interventions to improve work engagement. Contribution/value-add: This study contributes to the knowledge about the relationship between coping strategies and work engagement in South African organisations.

    Full Text Available Objective: To translate the English work-related acceptance and action questionnaire (WAAQ, make cross-cultural adaptations, and examine its psychometric properties when used by Chinese oncology nurses. Methods: After translation, the psychometric properties of the Chinese WAAQ were analyzed among 417 nurses, and content validity was determined by six experts. Results: Item-level content validity index (CVI values were between 0.83 and 1.00; scale-level CVI/universal agreement (S-CVI/UA and S-CVI/average were 0.86 and 0.98, respectively, which implicated a good content validity. The correlation of the Chinese WAAQ with AAQ-II (rs= −0.247, P < 0.001 suggested criterion validity, and those with General Health Questionnaire-12 (−0.250, <0.001 and general self-efficacy scale (0.491, <0.001 and Utrecht work engagement scale (UWES (0.439, <0.001 suggested convergent validity. Exploratory factor analysis identified a seven-item, one-factor structure of WAAQ. The Chinese version of WAAQ had high internal consistency (Cronbach's α = 0.920, with an item-total correlation coefficient of 0.702–0.828 (P < 0.05, split-half reliability of 0.933, and test-retest reliability of 0.772. Conclusions: The Chinese WAAQ is a reliable and valid tool for assessing psychological flexibility in Chinese oncology nurses.

    Full Text Available German Society for Sexual Research, Academy of Sexual Medicine and Society of Sexology formulated standards for evaluation and treatment of transsexuals. The creation of the standards involved Sophinette Becker, Hartmut A. G. Bosinski, Ulrich Clement, Wolf Eicher, Thomas M. Goerlich, Uwe Hartmann, Götz Kockott, Dieter Langer, Wilhelm E. Preuss, Gunter Schmidt, Alfred Springer, Reinhard Wille. Since 1980, the Federal Republic of Germany has a law on transsexualism, which regulates the right of the individual to change the sex. However, until now there were no specifically defined standards of assessment and treatment of transsexuals. For the first time, in 1979 Harry Benjamin invited the International Medical Association of Germany to revise the standards of medical care for gender dysphoria. The following standards of assessment and treatment of transsexuals have been developed at a conference convened by the German Society for Research Expert Committee under the leadership of Sophinette Becker. The review of currently valid standards for evaluation and treatment of transgender is the subject of this article

    Research purpose: The purpose of the research was to determine the relationship between psychological capital, work engagement and organisational commitment amongst call centre employees; and further, to determine whether psychological capital and work engagement hold predictive value for the organisational commitment of call centre employees. Motivation for the study: There is a gap in research in understanding and enabling positive resource capacities in highly stressful work contexts such as call centres. Research design, approach and method: A cross-sectional survey design was used. A sample of 106 call centre employees from a South African organisation participated in the research. The measuring instruments included a demographic questionnaire, the Psychological Capital Questionnaire (PCQ, the Utrecht Work Engagement Scale (UWES and the Organisational Commitment Questionnaire (OCQ. Main findings: Significant positive relationships were found between psychological capital, work engagement and organisational commitment. The results showed work engagement as being the only significant predictor of organisational commitment. Practical/managerial implications: Call centre employers need to develop and implement workplace interventions that would increase the psychological capital of call centre employees. Contribution/value-add: The research findings will benefit both call centre employees and management. The study highlighted the importance of the role of optimism as a subdimension of psychological capital in developing work engagement and organisational commitment amongst call centre employees.

    2003-01-01

    Collotype and Woodburytype are late 19th early 20th century continuous tone methods of reproducing photography in print, which do not have an underlying dot structure. The aesthetic and tactile qualities produced by these methods at their best, have never been surpassed. Woodburytype is the only photomechanical print process using a printing matrix and ink, that is capable of rendering true continuous tone; it also has the characteristic of rendering a photographic image by mapping a three-dimensional surface topography. Collotype"s absence of an underlying dot structure enables an image to be printed in as many colours as desired without creating any form of interference structure. Research at the Centre for Fine Print Research, UWE Bristol aims to recreate these processes for artists and photographers and assess their potential to create a digitally generated image printed in full colour and continuous tone that will not fade or deteriorate. Through this research the Centre seeks to provide a context in which the development of current four-colour CMYK printing may be viewed as an expedient rather than a logical route for the development of colour printing within the framework of digitally generated hard copy paper output.

    The aim of the present study is to demonstrate the distinctiveness of work engagement and workaholism by examining their relationships with sleep quality and job performance. A total of 447 nurses from 3 hospitals in Japan were surveyed using a self-administrated questionnaire including Utrecht Work Engagement Scale (UWES), the Dutch Workaholism Scale (DUWAS), questions on sleep quality (7 items) regarding (1) difficulty initiating sleep, (2) difficulty maintaining sleep, (3) early morning awakening, (4) dozing off or napping in daytime, (5) excessive daytime sleepiness at work, (6) difficulty awakening in the morning, and (7) tiredness awakening in the morning, and the World Health Organization Health Work Performance Questionnaire. The Structural Equation Modeling showed that, work engagement was positively related to sleep quality and job performance whereas workaholism negatively to sleep quality and job performance. The findings suggest that work engagement and workaholism are conceptually distinctive and that the former is positively and the latter is negatively related to well-being (i.e., good sleep quality and job performance).

    2004-07-01

    The present paper describes single-phase unidirectional transducers (SPUDT) cells with all fingers wider than lambda/8 while maintaining the unidirectional effect. The first solution is related to a SPUDT consisting of lambda/4 and lambda/2 wide fingers arranged in two tracks. Each track has no significant unidirectional effect. Both tracks form a waveguide, and the waveguide coupling generates the interaction of the tracks. As a result of that interaction, a unidirectional effect arises as verified by experiment. This transducer type is called double-track (DT) SPUDT. A second solution is suggested that includes, in contrast to distributed acoustic reflection transducer (DART), electrode width control (EWC), and Hunsinger cells, SPUDT cell fingers with one and the same width only. Cell types with lambda/6, lambda/5, and lambda/3 wide fingers called uniform width electrode (UWE) cells are considered. One of these cell types, including exclusively lambda/5 wide fingers, is experimentally investigated and a unidirectional effect is found. Moreover, a filter example using the lambda/5 cell type has been designed for reducing SPUDT reflections. The echo suppression expected could be verified experimentally. No waveguide coupling is required for this cell type.

It is very common in Southeast Asia but has started to spread to Europe and North America. OSF can lead to squamous cell carcinoma, a risk that is further increased by concomitant tobacco consumption. OSF is a diagnosis based on clinical symptoms and confirmation by histopathology. Hypovascularity leading to blanching of the oral mucosa, staining of teeth and gingiva, and trismus are major symptoms. Major constituents of betel quid are arecoline from betel nuts and copper, which are responsible for fibroblast dysfunction and fibrosis. A variety of extracellular and intracellular signaling pathways might be involved. Treatment of OSF is difficult, as not many large, randomized controlled trials have been conducted. The principal actions of drug therapy include antifibrotic, anti-inflammatory, and antioxygen radical mechanisms. Potential new drugs are on the horizon. Surgery may be necessary in advanced cases of trismus. Prevention is most important, as no healing can be achieved with available treatments. Keywords: betel nut, betel quid, oral disease, squamous cell carcinoma, tobacco, fibrosis

    Research purpose: This study explored possible differences in the Job Demands-Resources model (JD-R as predictor of overall work engagement, dedication only and work-based identity, through comparative predictive analyses. Motivation for the study: This study may shed light on the dedication component of work engagement. Currently no literature indicates that the JD-R model has been used to predict work-based identity. Research design: A census-based survey was conducted amongst a target population of 23134 employees that yielded a sample of 2429 (a response rate of about 10.5%. The Job Demands- Resources scale (JDRS was used to measure job demands and job resources. A work-based identity scale was developed for this study. Work engagement was studied with the Utrecht Work Engagement Scale (UWES. Factor and reliability analyses were conducted on the scales and general multiple regression models were used in the predictive analyses. Main findings: The JD-R model yielded a greater amount of variance in dedication than in work engagement. It, however, yielded the greatest amount of variance in work-based identity, with job resources being its strongest predictor. Practical/managerial implications: Identification and work engagement levels can be improved by managing job resources and demands. Contribution/value-add: This study builds on the literature of the JD-R model by showing that it can be used to predict work-based identity.

    Full Text Available The increasing number of textbooks and handbooks on qualitative research reflects developments in qualitative research as a field. In this book review symposium—based on a "Meet the Author" Session at the European Sociological Association Conference in Glasgow in 2007—several recent examples of handbooks written or edited by Uwe FLICK are discussed by two commentators. The author of the books then adds his own comments and responses. The discussion covers four main issues. First, tensions between intensifying the reflexivity of qualitative research and consolidating it as a competitor on the market of research, research training and funding are discussed. A second issue is how handbooks contribute to bridging the gaps between different local or language-specific traditions of qualitative research. A third issue is how to integrate more strongly the idea of research design into the methodological discussion (and practice of qualitative research more strongly. A fourth issue is how to promote and assess the quality of qualitative research and overcome a "legitimation crisis". These issues are discussed by the authors of this book review symposium from different perspectives with a focus on teaching qualitative methodology and on the progress of qualitative research.

    Low work engagement may contribute towards decreased well-being and work performance. Evaluating, boosting and sustaining work engagement are therefore of interest to many organisations. However, the evidence on which to base interventions has not yet been synthesised. A systematic review with meta-analysis was conducted to assess the evidence for the effectiveness of work engagement interventions. A systematic literature search identified controlled workplace interventions employing a validated measure of work engagement. Most used the Utrecht Work Engagement Scale (UWES). Studies containing the relevant quantitative data underwent random-effects meta-analyses. Results were assessed for homogeneity, systematic sampling error, publication bias and quality. Twenty studies met the inclusion criteria and were categorised into four types of interventions: (i) personal resource building; (ii) job resource building; (iii) leadership training; and (iv) health promotion. The overall effect on work engagement was small, but positive, k  = 14, Hedges g  = 0.29, 95%-CI = 0.12-0.46. Moderator analyses revealed a significant result for intervention style, with a medium to large effect for group interventions. Heterogeneity between the studies was high, and the success of implementation varied. More studies are needed, and researchers are encouraged to collaborate closely with organisations to design interventions appropriate to individual contexts and settings, and include evaluations of intervention implementation. © 2016 The Authors.

    enriched in 13C as compared to that from beech (OL enrichment factor= 1.24 ± 0.13 per thousand). Along the soil profile the C isotopic signature (d13C) reflects the main vegetation signature being higher in pine than beech in the organic soil horizons (OL, OF and OH) down to the first mineral Ah horizon. At deeper horizons d13C value tends to equal that of the original beech soil indicating a limited influence of the afforested specie with depth even 100 years after afforestation. A consistent enrichment in d15N with depth was observed in the two profiles. This N enrichments have been related with progressive N losses being particularly pronounced in forest soils (Szpak, 2014 and refs therein). This phenomenon can be also related to migrations of N forms in a more evolved organic matter. In this view N losses in organic layers under beech seem to be less pronounced that under the alien pine. REFERENCES: Andreeva BD, Zech M, Glaser B, Erbajeva MA, Chimitdorgieva, Ermakova OD, Zech, W.

    . Structures down to sub-micrometer range and complex impedance measurements tools integrated at single chips are now affordable. Moreover, the introduction of alternative signals and data processing algorithms focuses on very fast and parallel electrical characterization which in turn pushes this technique to new applications and markets. Electrical impedance tomography today yields pictures in real time with a resolution that was impossible 10 years ago. The XVth International Conference on Electrical Bio-Impedance in conjunction with the XIVth Electrical Impedance Tomography ICEBI/EIT 2013 organized by the Institute for Bioprocessing and Analytical Measurement Techniques, Heilbad Heiligenstadt, Germany, together with the EIT-group at the University of Göttingen, Germany, brings world leading scientists in these fields together. It is a platform to present the latest developments in instrumentation and signal processing but also points to new applications, especially in the field of biosensors and non-linear phenomena. Two Keynote lectures will extend the view of the participants above the mainstream of bio-impedance measurement. Friederich Kremer (University of Leipzig) delivers the plenary lecture on broad bandwidth dielectric spectroscopy. New achievements in the research of ligand gated ionic channels will be presented by Klaus Benndorf (University of Jena). Leading scientists in the field of bio-impedance measurement, such as, Sverre Grimnes, Orjan Martinsen, Andrea Robitzki, Richard Bayford, Jan Gimsa and Mart Min will give lectures for students but also more experienced scientists in a pre-conference tutorial which is a good opportunity to learn or refresh the basics.

    Musculoskeletal pain is a common symptom and many people even with chronic pain continue to work. The aim of our study is to analyze how musculoskeletal pain affects work well-being by comparing work engagement in employees with or without pain, and how pain-related risk of disability is associated with work engagement. In a separate analysis, we also studied, how psychosocial factors are related to work engagement. This is a cross-sectional study of Finnish female employees of the city of Pori, Finland (PORi To Aid Against Threats (PORTAAT) study). Data was collected by trained study nurses and self-administrated questionnaires. Work well-being was measured by work engagement using Utrecht Work Engagement Scale (UWES-9) questionnaire and the burden of pain was measured by using the short version of Örebro Musculoskeletal Pain Screening Questionnaire (ÖMPSQ). Study population was divided into four groups: those without pain and the groups with low (I), medium (II) or high (III) ÖMPSQ score, reflecting increasing risk of long term disability due to musculoskeletal pain. The study nurse assessed psychosocial risk factors using defined core questions. We evaluated 702 female employees, 601 (86%) had suffered from musculoskeletal pain over the past 12 months, whereas 101 (14%) reported no pain at all. Pain was chronic (duration at least 3 months) in 465/601 (77%) subjects. Subjects with musculoskeletal pain were older, had higher BMI and were on sick leave more often than subjects without pain. Of the psychosocial risk factors, depression, type D personality, anxiety and hostility were significantly more common among subjects with musculoskeletal pain. Hypertension and the use of non-steroidal anti-inflammatory drugs were significantly more frequent in the musculoskeletal pain group. Quality of sleep and working capability were significantly better among persons without pain. Average weekly working hours were slightly higher among those with musculoskeletal pain. In

    biomass is being used for this purpose. We seek to establish a conversion factor between both methods, if required. Results show that both the GC and the HPLC method can be used for organic samples containing some silica, such as grass char. Further tests include silica-rich materials, such as soils. Ongoing methodological work aims at carbon isotope analysis (13C and 14C) on individual BPCAs isolated via HPLC. At present the HPLC method employs tetrabutyl ammonium bromide (TBAB) as a modifier for the liquid phase. TBAB is not volatile and contains carbon, it therefore prevents carbon isotopic analysis on isolated BPCAs. References Brodowski, S., Rodionov, A., Haumeier, L., Glaser, B., Amelung, W.

    Research purpose: The purpose of the research was to determine the relationship between happiness, work engagement and organisational commitment and to determine whether happiness and work engagement hold predictive value for the organisational commitment of support staff. Motivation for the study: This study aims to enable the identification of a link between happiness, work engagement and organisational commitment and to identify a predictive value of the model. Research design, approach and method: The researchers used a cross-sectional survey design. They used a sample of 123 (N = 123 support staff members from a tertiary education institution in South Africa. The researchers used four demographic questionnaires for the research. These were the ‘Satisfaction with Life Scale’ (SWLS, the ‘Well-Being Questionnaire’ (WBQ, the ‘Utrecht Work Engagement Scale’ (UWES and the ‘Organisational Commitment Questionnaire’ (OCQ. Main findings: The researchers found a significant positive relationship between affective organisational commitment and work engagement, as well as between affective organisational commitment and happiness (as the SWLS and WBQ measure. They found a significant positive relationship between work engagement and happiness. Finally, the results showed that happiness and work engagement have predictive value for affective organisational commitment. Practical/managerial implications: Happiness and work engagement have predictive value for affective organisational commitment. Therefore, institutions should carefully tailor any implementation programme or initiative to address this relationship. Contribution/value-add: The findings will benefit both managers and workers. Institutions should consider evaluating the levels of happiness and work engagement of their support staff to address the issue of the organisational commitment of their employees.

    Engagement is an emerging job attitude that purports to measure employees' psychological presence at and involvement in their work. This research compares three academic approaches to engagement, and makes recommendations regarding the most appropriate conceptualisation and measurement of the construct in future research. The current research also investigates whether any of these three approaches to engagement contribute unique variance to the prediction of turnover intentions above and beyond the predictive capacity of alternative constructs. An online survey was taken by 382 employees and managers from a mid-sized financial institution. Results failed to support either a multi- or unidimensional factor structure for the Utrecht Work Engagement Scale (UWES) engagement measure. For the Shirom-Melamed Vigor Measure (SMVM), a multi-dimensional structure was identified as a good fit, while a unidimensional structure fit poorly. The uni-factorial structure of Britt's engagement measure was confirmed. The Schaufeli measure of engagement was a strong predictor of work outcomes; however, when controlling for job satisfaction and affective commitment, that measure lost its ability to predict intentions to leave. Two components of the Shirom vigor measure held their predictive validity. Collectively, these findings suggest that the Shirom vigor measure may provide better insight into whether and how much a person is 'into' his or her job. The Schaufeli measure was a good predictor of important work outcomes, but when job satisfaction and affective commitment were controlled, it lost its predictive validity. We were not able to confirm the three-factor structure of the Schaufeli measure. Two components of the Shirom vigor measure predicted turnover intentions after controlling for job satisfaction and affective commitment, suggesting less overlap with those constructs than the Schaufeli measure of engagement. This research adds important information on the nature of

    Background: Considering the overall tendency in psychology, researchers in the field of work and organizational psychology have become progressively interested in employees' effective and optimistic experiments at work such as work engagement. This study was conducted to investigate 2 main purposes: assessing the psychometric properties of the Utrecht Work Engagement Scale, and finding any association between work engagement and burnout in nurses. Methods: The present methodological study was conducted in 2015 and included 248 females and 34 males with 6 months to 30 years of job experience. After the translation process, face and content validity were calculated by qualitative and quantitative methods. Moreover, content validation ratio, scale-level content validity index and item-level content validity index were measured for this scale. Construct validity was determined by factor analysis. Moreover, internal consistency and stability reliability were assessed. Factor analysis, test-retest, Cronbach's alpha, and association analysis were used as statistical methods. Results: Face and content validity were acceptable. Exploratory factor analysis suggested a new 3- factor model. In this new model, some items from the construct model of the original version were dislocated with the same 17 items. The new model was confirmed by divergent Copenhagen Burnout Inventory as the Persian version of UWES. Internal consistency reliability for the total scale and the subscales was 0.76 to 0.89. Results from Pearson correlation test indicated a high degree of test-retest reliability (r = 0. 89). ICC was also 0.91. Engagement was negatively related to burnout and overtime per month, whereas it was positively related with age and job experiment. Conclusion: The Persian 3- factor model of Utrecht Work Engagement Scale is a valid and reliable instrument to measure work engagement in Iranian nurses as well as in other medical professionals.

    Stress-related health problems (e.g., work-related exhaustion) are a societal concern in many postindustrial countries. Experience suggests that early detection and intervention are crucial in preventing long-term negative consequences. In the present study, we benchmark a new tool for early identification of work-related exhaustion-the Lund University Checklist for Incipient Exhaustion (LUCIE)-against other contextually relevant inventories and two contemporary Swedish screening scales. A cross-sectional population sample (n = 1355) completed: LUCIE, Karolinska Exhaustion Disorder Scale (KEDS), Self-reported Exhaustion Disorder Scale (s-ED), Shirom-Melamed Burnout Questionnaire (SMBQ), Utrecht Work Engagement Scale (UWES-9), Job Content Questionnaire (JCQ), Big Five Inventory (BFI), and items concerning work-family interference and stress in private life. Increasing signs of exhaustion on LUCIE were positively associated with signs of exhaustion on KEDS and s-ED. The prevalence rates were 13.4, 13.8 and 7.8 %, respectively (3.8 % were identified by all three instruments). Increasing signs of exhaustion on LUCIE were also positively associated with reports of burnout, job demands, stress in private life, family-to-work interference and neuroticism as well as negatively associated with reports of job control, job support and work engagement. LUCIE, which is intended to detect pre-stages of ED, exhibits logical and coherent positive relations with KEDS and s-ED as well as other conceptually similar inventories. The results suggest that LUCIE has the potential to detect mild states of exhaustion (possibly representing pre-stages to ED) that if not brought to the attention of the healthcare system and treated, may develop in to ED. The prospective validity remains to be evaluated.

  13. Teleseism-based Relative Time Corrections for Modern Analyses of Digitized Analog Seismograms

    With modern-day instruments and seismic networks timed by GPS systems, synchronization of data streams is all but a forgone conclusion. However, during the analog era, when each station had its own clock, comparing data timing from different stations was a far more daunting prospect. Today, with recently developed methods by which analog data can be digitized, having the ability to accurately reconcile the timings of two separate stations would open decades worth of data to modern analyses. For example, one possible and exciting application would be using noise interferometry with digitized analog data in order to investigate changing structural features (on a volcano for example) over a much longer timescale than was previously possible. With this in mind, we introduce a new approach to sync time between stations based on teleseismic arrivals. P-wave arrivals are identified at stations for pairs of earthquakes from the digital and analog eras that have nearly identical distances, locations, and depths. Assuming accurate timing of the modern data, relative time corrections between a pair of stations can then be inferred for the analog data. This method for time correction depends upon the analog stations having modern equivalents, and both having sufficiently long durations of operation to allow for recording of usable teleseismic events. The Hawaii Volcano Observatory (HVO) network is an especially ideal environment for this, as it not only has a large and well-preserved collection of analog seismograms, but also has a long operating history (1912 - present) with many of the older stations having modern equivalents. As such, the scope of this project is to calculate and apply relative time corrections to analog data from two HVO stations, HILB (1919-present) and UWE (1928-present)(HILB now part of Pacific Tsunami network). Further application of this method could be for investigation of the effects of relative clock-drift, that is, the determining factor for how

If the patient has a severe, extended, or treatment-recalcitrant course of herpes zoster, this must be a red flag to search for underlying pathologies. Here, we report about a 64-year-old male patient with diabetes, who came to our emergency department because of general malaise, fever, chills, and a pronounced nuchal and facial swelling on the left side. Based on herpetiform-grouped vesicles and yellowish crusts, an impetiginized facial herpes zoster was diagnosed, and combined antiviral and antibiotic treatment was initiated. He was HIV negative. Despite intensified treatment, his situation worsened. We observed blasts in peripheral blood, but bone marrow biopsy was initially denied. Some days later after deterioration of his disease, he accepted further diagnostics. A myelodysplastic syndrome with blast excess (refractory anemia and blast excess II, RAEB II could be confirmed. The following translocations were detected: t(2;12(p13; q13 and t(6;9(p22;q34. REAB II has an unfortunate prognosis. Cytoreductive treatment was initiated by the hemato-oncologist.

Forurening, globalisering, polarisering mellem rig og fattig, genmanipulation og informationseksplosion er de gennemgå- ende motiver og et truende kaos det gennemgående tema".

    This paper contributes to the ongoing debate on the extent to which climate and climatic change can have a negative impact on societies by triggering migration, or even contribute to conflict. It summarizes results from the transdisciplinary project Climate of migration (funded 2010-2014), whose innovative title was created by Franz Mauelshagen and Uwe Lübken. The overall goal of this project was to analyze the relation between climatic and socioeconomic parameters and major migration waves from southwest Germany to North America during the 19th century. The article assesses the extent to which climatic conditions triggered these migration waves. The century investigated was in general characterized by the Little Ice Age with three distinct cooling periods, causing major glacier advances in the alpine regions and numerous climatic extremes such as major floods, droughts and severe winter. Societal changes were tremendous, marked by the warfare during the Napoleonic era (until 1815), the abolition of serfdom (1817), the bourgeois revolution (1847/48), economic freedom (1862), the beginning of industrialization accompanied by large-scale rural-urban migration resulting in urban poverty, and finally by the foundation of the German Empire in 1871.The presented study is based on quantitative data and a qualitative, information-based discourse analysis. It considers climatic conditions as well as socioeconomic and political issues, leading to the hypothesis of a chain of effects ranging from unfavorable climatic conditions to a decrease in crop yields to rising cereal prices and finally to emigration. These circumstances were investigated extensively for the peak emigration years identified with each migration wave. Furthermore, the long-term relations between emigration and the prevailing climatic conditions, crop yields and cereal prices were statistically evaluated with a sequence of linear models which were significant with explanatory power between 22 and 38 %.

  18. Work-based identity and work engagement as potential antecedents of task performance and turnover intention: Unravelling a complex relationship

    2012-01-01

    Full Text Available Orientation: Work-based identity, used as a reference to the self, is the answer to the question ’Who am I at work?’ Work-related identities, derived from different social foci through identity formation processes, have as behavioural guides a significant influence on employee behaviour, which, in turn has an impact on work outcomes. Engagement, presented in different conceptualisations, is viewed by practitioners and academic researchers as an important antecedent of employee behaviour.Research purpose: The main purpose of the study was to investigate whether work-based identity and work engagement differed (in combination with personal alienation, helping behaviour and burnout as potential antecedents (amongst numerous others of task performance and turnover intention.Research design: A census-based sampling approach amongst 23 134 employees in the employment of an ICT company yielded a sample of 2429 usable questionnaires. Scales used in the study were the Maslach Burnout Inventory (MBI-HSS-20, Utrecht Work Engagement Scale (UWES, Work-based Identity, Personal Alienation, Helping Behaviour, Turnover Intention and Task Performance Scales.Main findings: The findings indicate that work-based identity and work engagement give similar appearing results as potential predictors of turnover intention and task performance. Practical/managerial implications: Reducing withdrawal behaviours and enhancing work performance are everyday challenges for organisations. Interventions focused on enhancing work-based identity and work engagement in the work environment should have a meaningful impact when these behaviours need to be addressed.Contribution/value-add: Work-based identity as a multidimensional construct has the potential, with further refinement, to become a valuable construct that can play a leading role in future work engagement research.

    Full Text Available Orientation: Understanding the impact of resilience and perceived organisational support on employee engagement in a competitive sales environment. Research purpose: The aim of this study was to explore the relationship between resilience, perceived organisational support and employee engagement among pharmaceutical sales employees in a competitive sales environment; and to establish whether resilience and perceived organisational support hold predictive value for employee engagement. Motivation for the study: Limited research has focused on the unique context of employee engagement as a construct in professional sales. A broader understanding of resilience and perceived organisational support can provide sales organisations with a lever to create an environment where sales employees are more fully engaged. Research design, approach and method: A quantitative, exploratory, cross-sectional survey approach was used. A sample of 125 sales representatives from a South African pharmaceutical organisation participated in the research. The measuring instruments included the Utrecht Work Engagement Scale (UWES, Brief Resilience Scale (BRS and the Perceived Organisational Support Scale (POS. Main findings: Perceived organisational support, but not resilience impacted employee engagement in a competitive sales environment. Practical and managerial implications: Sales organisations’ interventions to improve sales employee engagement should focus on perceived organisational support. Contribution: The individual role of each construct provided insight into the sales context. The relationship between the constructs offered a different lens through which the drivers of employee engagement in sales can be viewed. This study contributes towards sales literature by including positive psychology and organisational support in a model of employee engagement.

    The European Zebrafish Principal Investigator Meeting (EZPM) is an ideal forum for group leaders using this fantastic animal model not only to discuss science but also to strengthen their interactions, to push forward technological advances, and to define guidelines for the use of this fish in research. The city of Lisbon (Portugal) was voted by the European group leaders to be the setting for the 4th EZPM, and the organizing committee, composed by Leonor Saúde (iMM Lisboa, PT), Susana Lopes (CEDOC, PT), Michael Orger (Champalimaud Foundation, PT), Rui Oliveira (ISPA, PT), and António Jacinto (CEDOC, PT), was very enthusiastic to organize a productive event. The 4th EZPM took place from March 15 to 19 at Pavilhão do Conhecimento, a Science Museum and Educational Center winner of The Great Prize FAD of Arquitecture 1999 and The Society for Environmental Graphic Design Award 2011. Over 5 days, 135 group leaders (89 men and 46 women) coming from 19 different European countries and also from the United States, Turkey, Israel, Chile, and Singapore presented and discussed their recent research achievements. In addition to the scientific oral and poster presentations, the group leaders gathered in very lively community sessions on morphants versus mutants (chaired by Didier Stainier, Max Planck Institute for Heart and Lung Research, DE), funding issues (chaired by Uwe Strahle, KIT-ITG, DE), and gender equality (chaired by Corinne Houart, KCL, United Kingdom). One of the highlights of the 4th EZPM was the guided visit to Oceanário de Lisboa, an international award-winning place that celebrates life with a stunning display of living aquatic creatures.

    Objetivo El objetivo de este estudio es demostrar la distinción entre engagement y trabajolismo, estudiando su relación con la calidad del sueño y el desempeño laboral. Método Un total de 447 enfermeras de 3 hospitales de Japón fueron entrevistadas mediante un cuestionario autoadministrado que incluía la escala Utrecht (UWES, Utrecht Work Engagement Scale), la Escala de Adicción al Trabajo Holandesa (DUWAS, Dutch Workaholism Scale), preguntas sobre la calidad del sueño (7 ítems) con respecto a (1) dificultad para conciliar el sueño, (2) dificultad para mantener el sueño, (3) despertar temprano por la mañana, (4) dormirse o tomar siestas durante el día, (5) somnolencia diurna excesiva en el trabajo, (6) dificultad para despertarse por la mañana, y (7) despertar cansado en la mañana, y el Cuestionario sobre Salud y Desempeño (CSD) de la Organización Mundial de la Salud. Resultados Los modelos de ecuaciones estructurales demostraron que el engagement se relaciona positivamente con la calidad del sueño y el rendimiento laboral, mientras que el trabajolismo tiene una relación negativa con la calidad del sueño y el desempeño laboral. Conclusión Los resultados indican que el engagement y el trabajolismo son conceptualmente diferentes. El primero tiene una connotación positiva, mientras que el segundo se asocia de manera negativa al bienestar (buena calidad del sueño y buen rendimiento en el trabajo). PMID:26752805

    In the last few years international studies have reported on increase in burn-out and depressive symptoms among psychiatry residents. In the field of research, however, commitment and dedication are now being mentioned more frequently as positive factors that counterbalance burn-out. To find out how a group of Dutch psychiatry residents feel about their work, to discover their degree of burn-out and commitment and to clarify the various factors involved. 59 psychiatry residents from four teaching hospitals were asked to complete questionnaires concerning burn-out (U-BOS-C), commitment (UWES-15) and personality (BFI-NL). Respondents were also asked to describe how they felt about their experiences during their work and to give their views on the instruction and training they were receiving. In the U-BOS-C section only four trainees (almost 7%) met the criteria for burn-out. In the BFI-NL section the psychiatry residents obtained significantly lower scores on neuroticism and higher scores on empathy than did a comparable norm group of a similar age. The scores of the psychiatry residents indicated that the term 'being proud of your work' was significantly related to a feeling of commitment and particularly to all subscales that reflected commitment. In our study the percentage of psychiatry residents with burn-out is significantly lower than the percentage reported elsewhere in the literature. In fact, our results demonstrate that the psychiatry residents who were the subject of our study regarded themselves as being emotionally stable, friendly and committed to their work.

We herein describe the case of a 69-year-old male patient reporting uncontrolled movements of the right arm due to a muscle weakness, slurred speech, and paresthesia in the oral region some seconds after he had blown his nose. These neurological symptoms had improved dramatically within a few minutes and were completely regressive at admission to our hospital about two hours later. On transesophageal echocardiography (TEE a huge ASA associated with PFO was detected. Diagnosis of the large-sized ASA was also confirmed by cardiac magnetic resonance imaging. Due to the early complete recovery from his neurological symptoms, the patient was diagnosed with a transient ischemic attack (TIA. After nine days he was discharged in a good clinical condition under the treatment with oral anticoagulation. It is concluded that in cryptogenic or unexplained stroke or TIA TEE should always be performed to rule out ASA and PFO as potential sources for paradoxical embolism in those inconclusive clinical situations.

    2018-03-01

    A highly miniaturized Field Emission Electric Propulsion (FEEP) system is currently under development at TU Dresden, called NanoFEEP [1]. The highly miniaturized thruster heads are very compact and have a volume of less than 3 cm3 and a weight of less than 6 g each. One thruster is able to generate continuous thrust of up to 8 μN with short term peaks of up to 22 μN. The very compact design and low power consumption (heating power demand between 50 and 150 mW) are achieved by using Gallium as metal propellant with its low melting point of approximately 30 °C. This makes it possible to implement an electric propulsion system consisting of four thruster heads, two neutralizers and the necessary electronics on a 1U CubeSat with its strong limitation in space, weight and available power. Even formation flying of 1U CubeSats using an electric propulsion system is possible with this system, which is shown by the example of a currently planned cooperation project between Wuerzburg University, Zentrum fuer Telematik and TU Dresden. It is planned to use the NanoFEEP electric propulsion system on the UWE (University Wuerzburg Experimental) 1U CubeSat platform [2] to demonstrate orbit and two axis attitude control with our electric propulsion system NanoFEEP. We present the latest performance characteristics of the NanoFEEP thrusters and the highly miniaturized electronics. Additionally, the concept and the current status of a novel cold neutralizer chip using Carbon Nano Tubes (CNTs) is presented.

    Research purpose: The overall purpose of this study was to explore the relationship between total rewards and work engagement in a South African context and to determine which reward categories predict work engagement. The study further endeavoured to determine whether gender and age had a moderating effect on the relationship between total rewards and engagement. Motivation for the study: Statistics report that less than 30% of all working people are optimally engaged in their work. Considering that individuals spend more than a third of their lives at work committing themselves emotionally, physically and psychologically – research indicates that employees are no longer satisfied with traditional reward systems and want to feel valued and appreciated. Research approach, design and method: In this quantitative, cross-sectional research design using a non-probability convenience and purposive sampling strategy, 318 questionnaires were collected and analysed from financial institutions in Gauteng in which opinions were sought on the importance of different types of rewards structures and preferences, and how engaged they are in their workplace. The 17-item UWES and Nienaber total reward preference model were the chosen measuring instruments. Main findings: A small statistically significant correlation (r = 0.25; p < 0.05; small effect was found between total rewards and work engagement, and 12% of the variance of work engagement was explained. Only performance and career management significantly predicted work engagement. Practical/Managerial implications: Although small, the significant correlation between total rewards and work engagement implies that total rewards are important motivators for employees in the workplace. Of the total rewards scales tested, only performance and career management significantly predicted work engagement, suggesting that more research is needed. Organisations seeking to implement total reward strategies should pay specific

The aim of this study was to investigate trends in participation, age, and performance in the longest inline race in Europe, the Inline One-Eleven over 111 km, held between 1998 and 2009.Methods: The total number, age distribution, age at the time of the competition, and race times of male and female finishers at the Inline One-Eleven were analyzed.Results: Overall participation increased until 2003 but decreased thereafter. During the 12-year period, the relative participation in skaters younger than 40 years old decreased while relative participation increased for skaters older than 40 years. The mean top ten skating time was 199 ± 9 minutes (range: 189–220 minutes for men and 234 ± 17 minutes (range: 211–271 minutes for women, respectively. The gender difference in performance remained stable at 17% ± 5% across years.Conclusion: To summarize, although the participation of master long-distance inline skaters increased, the overall participation decreased across years in the Inline One-Eleven. The race times of the best female and male skaters stabilized across years with a gender difference in performance of 17% ± 5%. Further studies should focus on the participation in the international World Inline Cup races.Keywords: endurance, men, women, gender

    Full Text Available Orientation: It is important to investigate the determinants of well-being among working women. Given the unique demographic diversity within the South African context, differences in the experience of well-being among women are expected. Purpose: The study investigated the effects of age, race, marital status and educational status on psychological meaningfulness, life satisfaction, work–family conflict and social support of working women. Motivation: With the increase of women in the workplace, there is a need for knowledge and understanding of the factors that influence the well-being of women. This study aims to investigate demographic variables as determinants of well-being among working women. Method: Cross-sectional surveys were used to gather data from a sample (n = 540 of women from various South African companies. The Utrecht Work Engagement Scale (UWES, the Psychological Meaningfulness Scale (PMS, the Satisfaction with Life Scale (SWLS, the WorkRole Conflict Scale and the Job Demands Resources Scale (JDRS were administered. Results: Significant relationships were found between life satisfaction, work-to-family conflict and work engagement, respectively, and marital status. Higher levels of education showed significant relationships with life satisfaction and work-to-family conflict. Being white showed significant positive relationships with life satisfaction, work-to-family conflict and work engagement. With regard to social support and psychological meaningfulness, race explained significant amounts of variance in psychological meaningfulness, as did age. Practical, managerial and methodological implications: The findings indicate that the experiences of well-being among women vary by age, race, marital status and educational status. It is therefore imperative that human resource practitioners appropriately measure these differences, accommodate them in policies through relevant supportive practices and also champion these

  11. Scoping medical tourism and international hospital accreditation growth.

    2013-01-01

    Uwe Reinhardt stated that medical tourism can do to the US healthcare system what the Japanese automotive industry did to American carmakers after Japanese products developed a value for money and reliability reputation. Unlike cars, however, healthcare can seldom be test-driven. Quality is difficult to assess after an intervention (posteriori), therefore, it is frequently evaluated via accreditation before an intervention (a priori). This article aims to scope the growth in international accreditation and its relationship to medical tourism markets. Using self-reported data from Accreditation Canada, Joint Commission International (JCI) and Australian Council on Healthcare Standards (ACHS), this article examines how quickly international accreditation is increasing, where it is occurring and what providers have been accredited. Since January 2000, over 350 international hospitals have been accredited; the JCI's total nearly tripling between 2007-2011. Joint Commission International staff have conducted most international accreditation (over 90 per cent). Analysing which countries and regions where the most international accreditation has occurred indicates where the most active medical tourism markets are. However, providers will not solely be providing care for medical tourists. Accreditation will not mean that mistakes will never happen, but that accredited providers are more willing to learn from them, to varying degrees. If a provider has been accredited by a large international accreditor then patients should gain some reassurance that the care they receive is likely to be a good standard. The author questions whether commercializing international accreditation will improve quality, arguing that research is necessary to assess the accreditation of these growing markets.

    Full Text Available Orientation: Beneficiary contact moderates the relationship between authentic leadership and work engagement. Research purpose: The objective of this study was to examine the moderating effect of the breadth, depth and frequency of employee interaction with the beneficiaries of their work on the positive impact of authentic leadership on work engagement. Motivation for the study: Investigating the boundary conditions of the relationship between leaders and followers is vital to enhance the positive effect of leadership. Authentic leadership has not previously been examined with respect to beneficiary contact as a specific situational factor. The researchers therefore set out to ascertain whether beneficiary contact has a strengthening or weakening effect on the impact of authentic leadership on work engagement. Research design, approach and method: The researchers administered the Authentic Leadership Questionnaire (ALQ, the Utrecht Work Engagement Scale (UWES-9 and Grant’s scale on Beneficiary Contact. Main findings: The findings showed that beneficiary contact had a weakening effect on the positive relationship between authentic leadership and work engagement. Practical/managerial implications: Ideally, organisations create environments conducive to work engagement in which leadership plays an important role. This study found that one factor in the work environment, namely beneficiary contact, might have an adverse effect on the positive relationship that authentic leadership has on work engagement. Leaders should therefore take organisational contextual realities into account, such as regular, intense interaction of employees with the beneficiaries of their work. This situation could create strain for individual employees, requiring additional organisational support. Contribution/value-add: Organisations need to recognise the impact of beneficiary contact on the relationship between authentic leadership and work engagement. The researchers

    2013-11-29

    Uwe Neue developed a theoretical treatment to account for the adsorption of ions on mesopores of packing materials the walls of which are bonded to ionic ligands but left this work unfinished. We elaborated upon this treatment and refined it, based on the equivalence that he suggested between charged surface particles and a membrane that separates two ionic solutions but is impermeable to one specification. He had written that the electro-chemical potentials in both ionic solutions are equal (Donnan equilibrium). The equilibrium between the surface and the pore concentrations is accounted for by an homogeneous electrostatically modified Langmuir (EML) isotherm model. The theoretical results are presented for four different charge surface concentrations σ0=0, 0.001, 0.002, and 0.003C/m(2), using a phosphate buffer (W(S)pH=2.65) of ionic strength I=10mM. The average pore size, the specific surface area, and the specific pore volume of the stationary phase were Dp=140Å, Sp=182m(2)/g, and Vp=0.70cm(3)/g, respectively. The theoretical results provide the quantitative difference between the ionic strength, the pH, and the concentrations of all the ions in the pores and in the bulk eluent. The theory predicts (1) that the retention times of cations under linear conditions is lower and (2) that their band widths under overloaded conditions for a given retention factor shrinks when the surface charge density σ0 is increased. These theoretical results are in good agreement with experimental results published previously and explain them. Copyright © 2013 Elsevier B.V. All rights reserved.

    Full Text Available Abstract Background Stress-related health problems (e.g., work-related exhaustion are a societal concern in many postindustrial countries. Experience suggests that early detection and intervention are crucial in preventing long-term negative consequences. In the present study, we benchmark a new tool for early identification of work-related exhaustion–the Lund University Checklist for Incipient Exhaustion (LUCIE–against other contextually relevant inventories and two contemporary Swedish screening scales. Methods A cross-sectional population sample (n = 1355 completed: LUCIE, Karolinska Exhaustion Disorder Scale (KEDS, Self-reported Exhaustion Disorder Scale (s-ED, Shirom-Melamed Burnout Questionnaire (SMBQ, Utrecht Work Engagement Scale (UWES-9, Job Content Questionnaire (JCQ, Big Five Inventory (BFI, and items concerning work-family interference and stress in private life. Results Increasing signs of exhaustion on LUCIE were positively associated with signs of exhaustion on KEDS and s-ED. The prevalence rates were 13.4, 13.8 and 7.8 %, respectively (3.8 % were identified by all three instruments. Increasing signs of exhaustion on LUCIE were also positively associated with reports of burnout, job demands, stress in private life, family-to-work interference and neuroticism as well as negatively associated with reports of job control, job support and work engagement. Conclusions LUCIE, which is intended to detect pre-stages of ED, exhibits logical and coherent positive relations with KEDS and s-ED as well as other conceptually similar inventories. The results suggest that LUCIE has the potential to detect mild states of exhaustion (possibly representing pre-stages to ED that if not brought to the attention of the healthcare system and treated, may develop in to ED. The prospective validity remains to be evaluated.

The capsaicin 8% patch is a novel treatment option that directly targets the source of peripheral neuropathic pain. It can provide pain relief for up to 12 weeks in patients with peripheral neuropathic pain. Treatment with the capsaicin 8% patch follows a clearly defined procedure, and patch application must be carried out by a physician or a health care professional under the supervision of a physician. Nonetheless, in our experience, nurses often take the lead role in capsaicin 8% patch application without the involvement of a physician. We believe that the nurse's key role is of benefit to the patients, as he or she may be better placed, because of time constraints and patient relationships, to support the patient through the application procedure than a physician. Moreover, a number of frequently prescribed drugs, including botulinum toxin and infliximab, can be administered by health care professionals without the requirement for physician supervision. Here we argue that current guidance should be amended to remove the requirement for physician supervision during application of the capsaicin 8% patch.

    This volume contains a collection of contributions from the invited speakers at the 2014 edition of the International Conference on Many Particle Spectroscopy of Atoms, Molecules, Clusters and Surfaces held in Metz, France, from 15th to 18th July 2014. This biennial conference alternates with the ICPEAC satellite International Symposium on (e,2e), Double Photoionization and Related Topics, and is concerned with experimental and theoretical studies of radiation interactions with matter. These include many-body and electron-electron correlation effects in excitation, and in single and multiple ionization of atoms, molecules, clusters and surfaces with various projectiles: electrons, photons and ions. More than 80 scientists, from 19 different countries around the world, came together to discuss the most recent progress on these topics. The scientific programme included 28 invited talks and a poster session extending over the three days of the meeting. Amongst the 51 posters, 11 have been selected and were advertised through short talks. Besides, Professor Nora Berrah gave a talk in memory of Professor Uwe Becker who sadly passed away shortly after co-chairing the previous edition of this conference. Financial support from the Institut Jean Barriol, Laboratoire SRSMC, Groupement de Recherche THEMS (CNRS), Ville de Metz, Metz Métropole, Conseil Général de la Moselle and Région Lorraine is gratefully acknowledged. Finally, I would like to thank the members of the local committee and the staff of the Université de Lorraine for making the conference run smoothly, the International Advisory Board for building up the scientific programme, the sessions chairpersons, those who gave their valuable time in carefully refereeing the articles of this volume and last, but not least, all participants for contributing to lively and fruitful discussions throughout the meeting.

    Concerns about patient safety and reducing harm have led to a particular focus on initiatives that improve healthcare quality. However Quality Improvement (QI) initiatives have in the past typically faltered because they fail to fully engage healthcare professionals, resulting in apathy and resistance amongst this group of key stakeholders. Productive Ward: Releasing Time to Care (PW) is a ward-based QI programme created to help ward-based teams redesign and streamline the way that they work; leaving more time to care for patients. PW is designed to engage and empower ward-based teams to improve the safety, quality and delivery of care. The main objective of this study was to explore whether PW sustains the 'engagement' of ward-based teams by examining the longitudinal effect that the national QI programme had on the 'work-engagement' of ward-based teams in Ireland. Utilising the Utrecht Work Engagement Scale questionnaire (UWES-17), we surveyed nine PW (intervention) sites from typical acute Medical/Surgical, Rehabilitation and Elderly services (representing the entire cohort of a national phase of PW implementation in Ireland) and a cohort of matched control sites. The numbers surveyed from the PW group at T1 (up to 3 months after commencing the programme) totalled 253 ward-team members and 249 from the control group. At T2 (12 months later), the survey was repeated with 233 ward-team members from the PW sites and 236 from the control group. Overall findings demonstrated that those involved in the QI initiative had higher 'engagement' scores at T1 and T2 in comparison to the control group. Total 'engagement' score (TES), and its 3 dimensions, were all significantly higher in the PW group at T1, but only the Vigour dimension remained significantly higher at T2 (p = 0.006). Our results lend some support to the assertions of the PW initiative itself and suggest that when compared to a control group, ward-based teams involved in the QI programme are more likely

This holds particularly true for patients with psychiatric disorders undergoing treatment in a psychiatric hospital. To understand whether the benefits reported in the literature are mirrored in current treatment modalities, the aim of the present study was to assess the current state of PAEPs in psychiatric hospitals in the German-speaking part of Switzerland. Methods: All psychiatric hospitals (N=55 in the German-speaking part of Switzerland were contacted in spring 2014. Staff responsible for PAEPs were asked to complete an online questionnaire covering questions related to PAEPs such as type, frequency, staff training, treatment rationale, importance of PAEPs within the treatment strategy, and possible avenues to increase PAEPs. Results: Staff members of 48 different psychiatric hospitals completed the survey. Hospitals provided the following therapeutic treatments: relaxation techniques (100%, sports therapy (97%, activity-related psychotherapeutic interventions (95%, physiotherapy (85%, body therapies (59%, far-east techniques (57%, and hippotherapy (22%. Frequencies ranged from once/week to five times/week. Approximately 25% of patients participated in the PAEPs. Interventions were offered irrespective of psychiatric disorders. PAEP providers wanted and needed more vocational training. Conclusion: All participating psychiatric hospitals offer a broad variety of PAEPs in their treatment curricula. However, the majority of inpatients do not

In addition to the core symptoms such as impaired communication, difficulties in social interaction, and restricted and stereotypical patterns of behavior and interests, poor sleep and motor skill (MS deficits have also been observed in children with ASD. On the other hand, there is evidence that aerobic exercise training (AET has a positive impact on sleep, and that specific training improves MSs. Accordingly, the aim of the present pilot study was to investigate to what extent a combination of AET and MS training (MST would improve sleep and physical performance in a small sample of children with ASD. Method: Ten children with ASD (mean age: 10 years took part in the study. After a thorough medical examination and psychiatric assessment, children participated in thrice-weekly 60-minute sessions of AET and MST lasting for 3 consecutive weeks. Sleep was assessed both objectively (sleep-encephalography [sleep-EEG] and subjectively (parents’ questionnaire. MSs were assessed via standardized test batteries. Parents completed sleep and mood logs, and ratings of mood. Results: Mild-to-moderate insomnia was reported in 70% of children. Compared to nights without previous AET and MS, on nights following AET and MS, sleep efficiency increased (d=1.07, sleep onset latency shortened (d=0.38, and wake time after sleep onset decreased for 63% of the sample (d=1.09, as assessed via sleep-EEG.

Therefore, targeted actions are needed to improve physical health in people with MDDs, in addition to ongoing efforts to enhance psychological well-being. Meanwhile, the positive effects of exercise training on the treatment of MDDs are well documented, while compelling evidence exists that exercise interventions can improve cardiorespiratory fitness in clinically meaningful ways. On the flipside, the long-term effects of exercise therapy are still not well documented, and recent studies suggest that initial improvements in MDDs dissipate if regular exercise participation is discontinued after the end of interventions. A recent survey among Swiss psychiatric hospitals further shows that all institutions provide some form of physical activity and exercise program. However, only a limited number of patients participate in these programs, mainly because participation is voluntary and no particular efforts are undertaken to engage patients with the lowest physical activity levels. We argue that more systematic efforts are needed to fully exploit the potential of physical activity and exercise programs in psychiatric care. We also emphasize that initiating and maintaining regular physical activity among psychiatric patients is a major challenge because specific dysfunctional cognitive–emotional processes might interfere with their

    The German non-materialist medicine of the first half of the 19th century is presently a subject of advanced historical studies, carried out in Europe and USA. Until the mid-20th century, however, it was only the German authors who produced literature dedicated to the above-mentioned medicine. The purpose of this study is to present to the Polish reader the main trends in the German medical historiography that have been taking up the subject for 150 years. The historians of German medicine distinguished trends in the post-war period as the studies of the history of their native medical historiography developed. A Polish historian taking up the task of characterizing of the main methodological trends in German medical historiography is faced with the necessity to take position on the findings of German authors who took up the above-mentioned subject earlier. In my studies I worked mainly on the findings of the following authors: Nelly Tsouyopoulos, Urban Wiesing and Hans-Uwe Lammel. They served me as a guide to the old historical-medical literature that I managed to reach in the libraries of Dresden and Leipzig. Some of the German studies (H. Haeser, J. Petersen) were translated to Polish language and in those cases I leaned on the Polish translators. In this study I discuss the following methodological trends in historiography of German medicine of the 1st half of the 19th century: eclectic trends, philosophical trends, positivistic trends, neo-romantic trends, and social-cultural trends. I also present the analysis of theories of the most important representatives of the trends. Thanks to this I could reconstruct the process of shaping of the discussed epoch image in the light of various concepts of its description. As a result different characteristics of the epoch were grasped although the factography level they referred to was common. This study outlines also further developoment of the historiography of the discussed subject in the second half of the 20th

    Assessment of economically optimal water management and geospatial potential for large-scale water storage Weerasinghe, Harshi; Schneider, Uwe A Water is an essential but limited and vulnerable resource for all socio-economic development and for maintaining healthy ecosystems. Water scarcity accelerated due to population expansion, improved living standards, and rapid growth in economic activities, has profound environmental and social implications. These include severe environmental degradation, declining groundwater levels, and increasing problems of water conflicts. Water scarcity is predicted to be one of the key factors limiting development in the 21st century. Climate scientists have projected spatial and temporal changes in precipitation and changes in the probability of intense floods and droughts in the future. As scarcity of accessible and usable water increases, demand for efficient water management and adaptation strategies increases as well. Addressing water scarcity requires an intersectoral and multidisciplinary approach in managing water resources. This would in return safeguard the social welfare and the economical benefit to be at their optimal balance without compromising the sustainability of ecosystems. This paper presents a geographically explicit method to assess the potential for water storage with reservoirs and a dynamic model that identifies the dimensions and material requirements under an economically optimal water management plan. The methodology is applied to the Elbe and Nile river basins. Input data for geospatial analysis at watershed level are taken from global data repositories and include data on elevation, rainfall, soil texture, soil depth, drainage, land use and land cover; which are then downscaled to 1km spatial resolution. Runoff potential for different combinations of land use and hydraulic soil groups and for mean annual precipitation levels are derived by the SCS-CN method.

Sports medicine clinical rotations improve both medical students' and residents' musculoskeletal knowledge. Despite the importance of this knowledge, a standardized sports medicine curriculum in emergency medicine (EM does not exist. Hence, we developed a novel sports medicine rotation for EM residents to improve their musculoskeletal educational experience and to improve their knowledge in musculoskeletal medicine by teaching the evaluation and management of many common musculoskeletal disorders and injuries that are encountered in the emergency department. The University of Arizona has two distinct EM residency programs, South Campus (SC and University Campus (UC. The UC curriculum includes a traditional 4-week orthopedic rotation, which consistently rated poorly on evaluations by residents. Therefore, with the initiation of a new EM residency at SC, we replaced the standard orthopedic rotation with a novel sports medicine rotation for EM interns. This rotation includes attendance at sports medicine clinics with primary care and orthopedic sports medicine physicians, involvement in sport event coverage, assigned reading materials, didactic experiences, and an on-call schedule to assist with reductions in the emergency department. We analyzed postrotation surveys completed by residents, postrotation evaluations of the residents completed by primary care sports medicine faculty and orthopedic chief residents, as well as the

However, it is still unknown whether the individual clinical outcome of cellulite treatment with extracorporeal shock wave therapy can be predicted by the patient's individual cellulite grade at baseline, individual patient age, body mass index (BMI, weight, and/or height.Methods: Fourteen Caucasian females with cellulite were enrolled in a prospective, single-center, randomized, open-label Phase II study. The mean (± standard error of the mean cellulite grade at baseline was 2.5±0.09 and mean BMI was 22.8±1.17. All patients were treated with radial extracorporeal shock waves using the Swiss DolorClast® device (Electro Medical Systems, S.A., Nyon, Switzerland. Patients were treated unilaterally with 2 weekly treatments for 4 weeks on a randomly selected side (left or right, totaling eight treatments on the selected side. Treatment was performed at 3.5–4.0 bar, with 15,000 impulses per session applied at 15 Hz. Impulses were homogeneously distributed over the posterior thigh and buttock area (resulting in 7,500 impulses per area. Treatment success was evaluated after the last treatment and 4 weeks later by clinical examination, photographic documentation, contact thermography, and patient satisfaction questionnaires.Results: The mean cellulite grade improved from 2.5±0.09 at baseline to 1.57±0.18 after the last treatment (ie, mean δ-1 was 0.93 cellulite grades and 1.68±0.16 at follow-up (ie, mean δ-2 was 0.82 cellulite grades.

Previous studies showed a direct association between increased perfectionism and poor sleep, though without taking into account possible mediating factors. Here, we tested the hypothesis that perfectionism was directly associated with poor sleep, and that this association collapsed, if mediating factors such as stress and poor emotion regulation were taken into account. Methods: Three hundred and forty six young adult students (M=23.87 years completed questionnaires relating to perfectionism traits, sleep, and psychological functioning such as stress perception, coping with stress, emotion regulation, and mental toughness. Results: Perfectionism was directly associated with poor sleep and poor psychological functioning. When stress, poor coping, and poor emotion regulation were entered in the equation, perfectionism traits no longer contributed substantively to the explanation

The orphan and structurally unique receptor small heterodimer partner 1 (syn NR0B2 is not only known for its modulation of drug response, but has also been reported to be involved in hepatocellular carcinogenesis. Indeed, previous studies show that NR0B2 is downregulated in human hepatocellular carcinoma, suggesting that NR0B2 acts as a tumor suppressor via inhibition of cellular growth and activation of apoptosis in this tumor entity. The aim of our study was to elucidate whether NR0B2 may also play a role in other tumor entities. Comparing NR0B2 expression in renal cell carcinoma and adjacent nonmalignant transformed tissue revealed significant downregulation in vivo. Additionally, the impact of heterologous expression of NR0B2 on cell cycle progression and proliferation in cells of renal origin was characterized. Monitoring fluorescence intensity of resazurin turnover in RCC-EW cells revealed no significant differences in metabolic activity in the presence of NR0B2. However, there was a significant decrease of cellular proliferation in cells overexpressing this NR, and NR0B2 was more efficient than currently used antiproliferative agents. Furthermore, flow cytometry analysis showed that heterologous overexpression of NR0B2 significantly reduced the amount of cells passing the G1 phase, while on

    Physician-rating websites (PRWs) may lead to quality improvements in case they enable and establish a peer-to-peer communication between patients and physicians. Yet, we know little about whether and how physicians respond on the Web to patient ratings. The objective of this study was to describe trends in physicians' Web-based responses to patient ratings over time, to identify what physician characteristics influence Web-based responses, and to examine the topics physicians are likely to respond to. We analyzed physician responses to more than 1 million patient ratings displayed on the German PRW, jameda, from 2010 to 2015. Quantitative analysis contained chi-square analyses and the Mann-Whitney U test. Quantitative content techniques were applied to determine the topics physicians respond to based on a randomly selected sample of 600 Web-based ratings and corresponding physician responses. Overall, physicians responded to 1.58% (16,640/1,052,347) of all Web-based ratings, with an increasing trend over time from 0.70% (157/22,355) in 2010 to 1.88% (6377/339,919) in 2015. Web-based ratings that were responded to had significantly worse rating results than ratings that were not responded to (2.15 vs 1.74, PWeb to patient ratings differ significantly from nonresponders regarding several characteristics such as gender and patient recommendation results (PWeb to patient ratings. This is likely because of (1) the low awareness of PRWs among physicians, (2) the fact that only a few PRWs enable physicians to respond on the Web to patient ratings, and (3) the lack of an active moderator to establish peer-to-peer communication. PRW providers should foster more frequent communication between the patient and the physician and encourage physicians to respond on the Web to patient ratings. Further research is needed to learn more about the motivation of physicians to respond or not respond to Web-based patient ratings. ©Martin Emmert, Lisa Sauter, Lisa Jablonski, Uwe Sander

The risk of suffering from MS is 2.5–3.5 times greater in females than in males. While there is extant research on fatigue, depression, and cognitive impairment in patients with MS during its clinical course, there is a lack of research focusing on sleep, psychological functioning, and physical activity (PA at the point of disease onset. The aims of the present study were therefore, to assess the markers of mental toughness (MT as a dimension of psychological functioning, sleep disturbances (SD, and PA among patients at the moment of disease onset and to compare these with the corresponding values for healthy adolescents and young adults. Methods: A total of 23 patients with MS at disease onset (mean age =32.31 years; 91% females, 23 healthy adolescents (mean age =17.43 years; 82% females, and 25 healthy young adults (mean age =20.72 years; 80% females took part in the study. They completed questionnaires covering sociodemographic data, MT, SD, and PA. Results: Patients with MS had similar scores for MT traits as those in healthy

    The intention to leave surgical training, hereinafter referred as proxy of "attrition," is associated with poor well-being in the workplace. Attrition is suggested to diminish when residents possess job-crafting skills, that is, the ability to redefine their job in meaningful ways and maximize well-being at work by increasing structural and social resources and challenges and decreasing hindering demands. However, the evidence supporting this relationship is scant. This study sought to: 1) investigate to what extent residents possess job-crafting skills and compare residents' levels of job-crafting skills across years of residency training; 2) investigate the relationship between job crafting, well-being as measured by burnout and work-engagement rates, and the intention to leave; and 3) compare the levels of job-crafting skills and well-being between residents with and without serious intentions to leave. This cross sectional study was conducted in fifteen residency programs in Colombia. Surgical residents completed different questionnaires including the Dutch Job Crafting Scale (DJCS), MBI-Human Services Survey (MBI-HSS), Utrecht Work Engagement Scale (UWES-17) and an adapted version of the Nurse Turnover Intention Scale (NTIS). The objectives were addressed by independent analyses of variance (ANOVA), structural equation modeling techniques (SEM) and independent t-tests, respectively. A total of 202 residents participated. Residents generally scored high on their job-crafting skills to increase structural and social resources as well as challenging demands, but were less positive about their skills to reduce hindering demands. No differences across years of training were found. Job crafting correlated positively with work-engagement, which was inversely related to the intention to leave. Conversely, job crafting correlated negatively with burnout, which bore a positive relationship to the intention to leave. Residents with serious intentions to leave exhibited

    are still being processed. Nevertheless, preliminary results indicated that addition of biochar did not alter negatively physical properties (pH, EC) or composition of this alkaline soil, on the contrary biochar addition caused a slight improvement of the WHC and soil porosity. Those changes produced a faster development of plant shoots. However, at the end of the experiment, biochar amendment caused no significant increase on the agronomic production for any of the tested biochars. From these preliminary results, we conclude that biochar amendment improved physical-surficial characteristics of the calcic Cambisol from an agronomic point of view, but under the typical Mediterranean climate those changes seem to leave the harvested seed yields unaffected.

Moreover, Jügen Nührenberg showed that a number of other properties of the magnetic field can also be optimized simultaneously, allowing high equilibrium and stability limits to be achieved and thus opening up a route to an inherently steady-state fusion reactor. The ideas of Allen Boozer and Jürgen Nührenberg have revolutionized stellarator research. They have already partially been confirmed on the W7-AS and HSX stellarators, and provide the basis for the world's largest stellarator under construction, Wendelstein 7-X. The award of the 2010 Hannes Alfvén Prize to these two leading scientists underlines the development of understanding and transfer of knowledge in plasma physics. Invited papers by Allen Boozer and Jürgen Nührenberg are published as articles 124002 and 124003 in this special issue of Plasma Physics and Controlled Fusion.

The energy of ions impacting surfaces during plasma processing is crucial in determining both the properties of materials being deposited by plasmas and for the control of the etching of thin films. The independent control of the ion energy and the plasma density has been the object of intense industrial research. Current technologies for modifying the ion energy rely on the geometry of the plasma processing chamber or on applying low and high frequency RF power that is not phase locked. These techniques are either not applicable to some situations or have only been partially successful. The electrical asymmetry effect allows the ion energy and plasma

    shift towards higher frequencies. This frequency shift is due to the reduction of the effective resonance volume that results from the existence of a Stokes boundary layer at the outer librating wall. Due to the symmetry of the forcing not all possible modes can be excited. It is shown that only symmetric modes with respect to the rotation axis exist. From a fundamental perspective, the study might help to understand better inertial mode excitation in librating planets and moons where inertial waves are emitted from critical points on the inner or outer spherical boundary. Recently, Zhang et al. (2013) pointed out the resonance should not occur in symmetric librating bodies without precession. We will discuss how this assumption depends on the boundary conditions. It might turn out that even when the projection of the Euler (or Poincare) force on the modes is zero, the projection of the excited wave beams on the modes is non-zero. K. Zhang, K. H. Chan, X.

    Digital interventions have the potential to serve as cost-effective ways to manage occupational stress and well-being. However, little is known about the adoption of individual-level digital interventions at organizations. The aim of this paper is to study the effects of an unguided digital mental health intervention in occupational well-being and the factors that influence the adoption of the intervention. The intervention was based on acceptance and commitment therapy (ACT) and its aim was to teach skills for stress management and mental well-being. It was delivered via a mobile and a Web-based app that were offered to employees of two information and communication technology (ICT) companies. The primary outcome measures were perceived stress and work engagement, measured by a 1-item stress questionnaire (Stress) and the Utrecht Work Engagement Scale (UWES-9). The intervention process was evaluated regarding the change mechanisms and intervention stages using mixed methods. The initial interviews were conducted face-to-face with human resource managers (n=2) of both companies in August 2013. The participants were recruited via information sessions and email invitations. The intervention period took place between November 2013 and March 2014. The participants were asked to complete online questionnaires at baseline, two months, and four months after the baseline measurement. The final phone interviews for the volunteer participants (n=17) and the human resource managers (n=2) were conducted in April to May 2014, five months after the baseline. Of all the employees, only 27 (8.1%, 27/332) took the app into use, with a mean use of 4.8 (SD 4.7) different days. In the beginning, well-being was on good level in both companies and no significant changes in well-being were observed. The activities of the intervention process failed to integrate the intervention into everyday activities at the workplace. Those who took the app into use experienced many benefits such as

  7. An Imminent Revolution in Modeling Interactions of Ice Sheets With Climate

    2008-12-01

    Modeling continental ice sheets was inaugurated by meteorologists William Budd and Uwe Radok, with mathematician Richard Jenssen, in 1971. Their model calculated the thermal and mechanical regime using measured surface accumulation rates, temperatures, and elevations, and bed topography. This top-down approach delivered a basal thermal regime of temperatures or melting rates for an assumed basal geothermal heat flux. When Philippe Huybrechts and others incorporated time, largely unknownpast surface conditions had a major effect on present basal thermal conditions. This approach produced ice-sheet models with only a slow response to external forcing, whereas the glacial geological record and climate records from ice and ocean cores show that ice sheets can have rapid changes in size and shape independent of external forcing. These top-down models were wholly inadequate for reconstructing former ice sheets at the LGM for CLIMAP in 1981. Ice-sheet areas,elevations, and volumes provided the albedo, surface topography, and sea-surface area as input to climate models. A bottom-up model based on dated glacial geology was developed to provide the areal extent and basal thermal regime of ice sheets at the LGM. Basal thermal conditions determined ice-bed coupling and therefore the elevation of ice sheets. High convex ice surfaces for slow sheet flow lower about 20 percent when a frozen bed becomes thawed. As further basal melting drowns bedrock bumps that "pin" basal ice, the ice surface becomes concave in fast stream flow that ends as low floating ice shelves at marine ice margins. A revolution in modeling interactions between glaciation, climate, and sea level is driven by new Greenland and Antarctic data from Earth-orbiting satellites, airborne and surface traverses, and deep drilling. We anticipate continuous data acquisition of surface albedo, accumulation/ablation rates, elevations, velocities, and temperatures over a whole ice sheet, mapping basal thermal conditions

  9. Work engagement and meaningful work across generational cohorts

    Full Text Available Orientation: Engaging employees and providing employees with a sense of meaning at work is not a one-size-fits-all approach. Although research has shown that differences between work engagement and meaningful work amongst generational cohorts exist, results are still inconclusive. With age becoming increasingly more important as a diversity factor, a better understanding of the dynamics between work engagement and meaningful work across different generational cohorts is necessary to design the right strategy for each organisation’s unique parameters. Research purpose: The aim of this study was to determine whether there is a relationship between work engagement and meaningful work and whether there are significant variances between the levels of work engagement and meaningful work between different generational cohorts. Motivation for study: Work engagement has consistently been highlighted by researchers and human resources experts as a recommended solution to provide companies with the upper hand when it comes to creating a competitive edge. Yet, levels of work engagement are far from ideal, requiring intensified efforts to identify solutions towards raising overall engagement levels. In recent years, much of the focus in terms of generating engagement has been aimed in the direction of financial rewards and other benefits; some organisational experts are of the opinion that a shift is occurring towards meaningful work instead of monetary rewards as the driver of engagement. The changing nature of the work landscape also suggests that generational cohorts experience work engagement and meaningful work differently. Understanding these complexities is mandatory in creating solutions towards improving levels of engagement and meaningful work. Research approach, design and method: A cross-sectional quantitative research approach has been followed. The Utrecht Work Engagement Scale (UWES and Psychological Meaningful Scale (PMS were administered

    This is a call for contributions to a special issue of Journal of Physics A: Mathematical and Theoretical dedicated to quantum physics with non-Hermitian operators. The main motivation behind this special issue is to gather together recent results, developments and open problems in this rapidly evolving field of research in a single comprehensive volume. We expect that such a special issue will become a valuable reference for the broad scientific community working in mathematical and theoretical physics. The issue will be open to all contributions containing new results on non-Hermitian theories which are explicitly PT-symmetric and/or pseudo-Hermitian or quasi-Hermitian. The main novelties in the past years in this area have been many experimental observations, realizations, and applications of PT symmetric Hamiltonians in optics and microwave cavities.

    of aperiodic order in two dimensions and used in modelling quasicrystalline materials, some ten years before quasicrystals were first seen in experiment. The conference excursion and dinner centred on the historic waterfront area of this 800-year old city that was designated European Capital of Culture in 2008. The enjoyment of the ferry trip on the Mersey and subsequent walk to the Albert dock museums was greatly enhanced by the fine weather, which lasted throughout the entire conference week. The guests of honour at the conference dinner were Professor Sir Roger Penrose FRS and Professor Alan L Mackay FRS, bringing together two distinguished UK scientists who made seminal contributions to the subject. Besides the scientific programme, the conference also offered a presentation by the author Ann Lingard, whose latest novel The Embalmer's Book of Recipes features a mathematician working on quasicrystals at the University of Liverpool as its main character. A related EPSRC-supported workshop on Mathematical Aspects of Aperiodic Order, organised by Alex Clark, John Hunton and Uwe Grimm, was held in Leicester in the week preceding the conference, and attracted about 40 participants. It is not possible to organise a conference without the help and support of a large number of people, and we would like to take this opportunity to acknowledge the support of everyone who was involved in organising and running this conference. We would like to thank the IUCr Aperiodic Commission, and in particular its chair Professor Marc de Boissieu, who not only entrusted us with hosting the event, but acted as the International Advisory Committee and provided valuable advice and guidance. We are indebted to the members of the International Programme Committee, who helped to put together an exciting programme by suggesting invited speakers and selecting presentations for contributed plenary talks. We are immensely grateful to all members of the National Organising Committee, who provided

  13. Once a myth, now an object of study - How the perception of comets has changed over the centuries

    2004-02-01

    In February 2004, Rosetta will be setting off on its long journey through our solar system to meet up with Comet Churyumov-Gerasimenko. It will take the European Space Agency (ESA) space probe ten years to reach its destination. The comet, which moves in an elliptical orbit around the Sun, will at rendezvous be some 675 million kilometres from the Sun, near the point in its orbit farthest from the Sun. The meeting point was not chosen at random: at this point the comet is still barely active, it is still in fact a frozen lump of ice and interplanetary dust, in all probability the matter from which our solar system emerged four and a half billion years ago. Rosetta’s job is to find out more about these strange bodies that travel through our solar system. As it moves on, the comet will begin to change. As it approaches the Sun, it will - like all comets - become active: in the warmth of the Sun’s rays, the ices evaporate, tearing small dust particles from the surface. This produces the comet head (the coma) and tail. Only these two phenomena are visible from Earth. The comet nucleus itself is far too tiny - Churyumov-Gerasimenko measures about 4 kilometres across - to be viewed from Earth. As Dr Uwe Keller of the Max Planck Institute for Aeronomy in Kaltenburg-Lindau, the scientist responsible for the Osiris camera carried by Rosetta, explains, “Formation of the coma and tail during solar flyby skims several metres of matter off the comet’s surface. In the case of a small comet like Churyumov-Gerasimenko, the shrinkage is a good 1% each time round.” As it flies past the Sun every 6.6 years it can look forward to a short future, especially on a cosmic timescale. Comets - a mystical view Visible cometary phenomena have fascinated human beings from time immemorial - and frightened them too. Even today mystical explanations prevail among some of the Earth’s peoples. The Andaman islanders, a primitive people living in the Gulf of Bengal, see comets as burning

    filaments, for both Xe and Sn. The embodiment of electrical discharge plasmas and laser-produced plasmas into commercially available EUV sources, with EUV powers that project to suitable levels, is presented in the fifth paper by Uwe Stamm of XTREME Technologies in Göttingen. For discharge produced plasmas, thermal loading and electrode erosion are significant issues. Vladimir Borisov and his colleagues, at the Troitsk Institute outside Moscow, address these issues and provide novel ideas for the multiplexing of several discharge plasmas feeding a single optical system. Igor Fomenkov and his colleagues at Cymer in San Diego describe issues associated with a dense plasma focus pinch, including a comparison of operations with both positive and negative polarity. In the eighth paper, Malcolm McGeoch of Plex in Massachusetts provides a theoretical description of the vaporization and ionization of spherical tin droplets in discharge plasma. Together this cluster of papers provides a broad review of the current status of high power EUV plasma sources for semiconductor manufacturing. This very current topic, of intense interest worldwide, is considered further in a book [4] of collected papers to become available in mid-2005. Additionally, a special journal issue emphasizing coherent EUV sources, albeit at lower average powers, is soon to appear [5].

    with a great response: not only did over thirty young colleagues register but also senior scientists registered for the course and were very active in discussions. The workshop was supported financially by Forschungszentrum Jülich and the ExtreMat Integrated Project, a programme for the development and study of new materials for extreme environments. We are very grateful to the staff of Forschungszentrum who helped with the organization. Our most cordial thanks and gratitude go to Yasmin Fattah, Angelika Hallmanns, Gabriele Knauf and Gerd Boeling for all their kindness and efficiency, which helped all of us to enjoy the meeting. We thank most sincerely our colleagues Gerald Pintsuk, Takeshi Hirai and Andrey Litnovsky for their most professional work in the construction and operation of the conference webpage, the preparation of the sessions and for all other elements that were vital for the smooth running of the meeting. We thank very much Marliese Felden and Ralf-Uwe Limbach who very kindly and professionally took care of the photographic documentation of the workshop. The proceedings of this workshop contains 67 peer-reviewed articles covering the contents of most of the invited presentations and a number of poster contributions which were pre-selected by the programme committee. The papers reflect the development and actual status of the field. We thank all participants for their contributions and the referees for their smooth and efficient peer-review. Thank you all for your hard work and co-operation. We are looking forward to seeing you at the next meeting; we invite you to come, though we are not yet able to say 'when' and 'where' we will meet next time. It is a special feature of this conference series that a new meeting is announced only when the community feels that there is substantial new material to be presented and discussed.

    lead to new fundamental understanding is illustrated well in the paper by Uwe Czarnetzki which describes a new method for separate control of flux and energy of ions reaching the surface of electrodes. Deborah O'Connell from Belfast has shown space and phase resolved mode transitions in rf inductively coupled plasmas obtained by optical emission measurements. At the same time an application of a similar rf discharge for the treatment of paper was presented by Irina Filatova from Belarus. Many applications of non-equilibrium plasmas depend on the development of plasma sources operating at atmospheric pressure and one such source that promises to be prominent in medicine is described by Timo Gans. In a similar way, practical considerations require studies of the injection of liquids into plasmas and progress on the development of one such source is described by Mathew Goeckner and his colleagues from Dallas. From the Institute Jožef Štefan in Slovenia and the group of Miran Mozetič we have a detailed review of their work on functionalization of organic materials by oxygen plasmas. Even higher density plasmas, where the collective phenomena dominate, show different degrees of non-equilibrium and one example presented here by Zoltan Donko deals with two dimensional plasma dust crystals and liquids, while the lecture by Jovo Vranješ from Belgium deals with the treatment of collisions in multicomponent plasmas. Finally we have papers on the transport of pollutants. The association of the two fields started initially through joint interest in some of the methods for removal of NOx and SOx, from electrostatic precipitation of industrial dust to dielectric barrier discharges. The joint work continued on the application of flowing afterglow plasma combined with a hollow cathode discharge in order to achieve a proton transfer mass analysis of organic volatile compounds and also on the possibilities of applying similar methods for solving transport equations.

    the origin of life on the Earth. The comet specialist Uwe Keller of the Max-Planck Institut fur Aeronomie, Germany, is one of the Giotto veterans who has helped with the planning of Rosetta. He was in charge of Giotto's camera. "Rosetta is the mission we are all waiting for," Dr Keller comments. "After I spent six years analysing our images of the Halley nucleus, I say that basic scientific assumptions about the nature of comets are still contradictory. We shall settle the arguments only by the close, prolonged inspection that Rosetta will make possible." Engineering the Rosetta mission To build up the speed needed to adopt the same orbit around the Sun as Comet Wirtanen, Rosetta must steal energy of motion from the planets, in a swingby of Mars and two swingbys of the Earth. During its far-flung manoeuvres in pursuit of the comet, Rosetta will inspect the asteroids Mimistrobell and Rodari at close quarters. When Rosetta is far from the Earth, or on the wrong side of the Sun, communication will be difficult. The spacecraft will therefore have a high degree of robotic self-reliance. It will also be capable of hibernating for more than two years without attention -- a technique devised by ESA for the later stages of the Giotto mission. Rosetta will rely on solar power, even when more than five times further than the Earth from the Sun. Special low-intensity solar cells are under development for Rosetta. Conditions in this farthest phase of Rosetta's voyage will be very chilly, but ESA's engineers are satisfied that the temperatures inside the spacecraft can be kept within limits by black paint, multilayer insulation and electric heaters. Despite its originality and sophistication, Rosetta will be just a flying box with solar arrays like wings, looking rather like a telecommunications satellite. "Keep it simple," is the motto of John Credland, ESA's project manager for Rosetta. "Simplicity brings reliability," he explains, "and that is my overriding concern for the

    project concerned the actual construction of a working solar radio interferometer, a rather complex instrument that allows measurements of the long-wavelength radiation from the Sun and to map the locations in the solar corona where this radiation originates. The antennae and receiver were designed for frequences around 550 and 750 MHz and were built by the team members themselves. Radio signals from the Sun (as interference fringes) were effectively observed with this instrument, documenting the excellent functioning of this advanced equipment. Germany: Ms. Dorothee Barth, Mr. Walter Czech (Teacher), Mr. Uwe Kranz, Ms. Karin Wieland (Immanuel-Kant-Gymnasium, Leinfelden-Echterdingen, Baden-Wurttemberg) Following a careful planning phase, systematic observations of the 14-magnitude planet Pluto were made with a CCD camera and a 30-cm telescope during 18 nights in the spring and summer of this year. Five nearby stars were used to calibrate the resulting photometric measurements. In the end, this programme was shown to achieve a very good photometric accuracy of about +- 0.2 magnitude per measurement. The variation of Pluto's brightness was found to be about 0.7 magnitude for this particular instrumental combination (no filtre). It was thus possible to draw the lightcurve which was found to be in complete agreement with the established 6.4 day rotation period. Greece: Ms. Agni Ioannidi, Ms. Elena Katifori, Mr. Vassilis Samiotis, Mr. Vassillos Tzotzes (Teacher) (Varvakio Experimental Lyceum, Athens) The project starts out from a star of 1.56 solar mass and a certain density. From this, its size, luminosity, temperature, pressure and other parameters are calculated. With an analogue to the Titius-Bode law for planetary distances, a new planetary system is constructed. It has 5 planets, 3 of which are of the terrestrial type and the other 2 are giant gas planets, larger than Jupiter. Their physical characteristics are calculated.

This wide collaboration was carried out in close cooperation with and profiting from the professional experience of ESO that has built and now operates the Paranal Observatory, ensuring the proper interfacing between MIDI and the VLTI needed for high-performance interferometric measurements. Brief history of the MIDI project Work on the mid-infraredinterferometric instrument MIDI started in 1997 when MPIA proposed to ESO to build such a facility that would conform with ESO's plans for interferometric observations with the VLT telescopes and which would most probably become the first of its kind worldwide. Soon thereafter, the Netherlands Science Organization NOVA with ASTRON and NEVEC and the other partner institutes in France, the Netherlands and Germany joined the project. With Christoph Leinert and Uwe Graser from MPIA teaming up to lead the project, more than two dozen engineers, astronomers and students worked intensively for three and a half years on the planning, design and production, before the integration of this highly complex instrument could start at the Max-Planck-Institut für Astronomie in Heidelberg. This took place in September 2001 and was followed by a period of extensive instrumental tests. Much preparatory work had to be done at Paranal in parallel, to be ready for a smooth installation of MIDI [3]. After a positive, concluding status review of MIDI by ESO in September 2002, the many parts of
