From occupational challenges to sleep: examining the relationship between workload and sleep quality, and their association with workplace incivility and post-work recovery
No full textVsakodnevno se zaposleni srečujejo z delovnimi obremenitvami, pri čemer porabljajo energetske vire, ki jih morajo nadoknaditi v času počitka in s kakovostnim spanjem. V magistrskem delu smo izvedli dnevniško raziskavo in preučevali povezave med različnimi vrstami delovnih obremenitev (emocionalne, kvantitativne in kognitivne), sprostitvijo kot izkušnjo počitka in subjektivno kakovostjo spanja. Namen je bil tudi preučiti, kako doživljanje nevljudnosti na delovnem mestu napoveduje kakovost spanja ter možnost, da sprostitev mediira odnos med navedenima konstruktoma. V raziskavi je sodelovalo 45 zaposlenih, ki so šest dni zapored trikrat dnevno izpolnjevali dnevniške vprašalnike. Večnivojsko modeliranje omogoča preučevanje kompleksnejših povezav. Rezultati mediacijskih analiz so pokazali, da sprostitev ni pomemben mediator v odnosu med delovnimi obremenitvami in subjektivno kakovostjo spanja niti med nevljudnostjo na delovnem mestu in kakovostjo spanja na dnevni ravni. Neposredni učinek je bil ugotovljen samo pri emocionalnih obremenitvah, ki statistično pomembno negativno napovedujejo spanje na dnevni ravni. Ugotovili smo, da nevljudnost na delovnem mestu statistično pomembno negativno napoveduje sprostitev. Rezultati nam nudijo pomemben vpogled v povezave delovnih obremenitev in nevljudnosti na kakovost spanja zaposlenih ter vlogo sprostitve kot možnega mediatorja v odnosih na dnevni ravni. Rezultati spodbujajo nadaljnje raziskave z večjimi vzorci in drugačnimi mediatorji ter dejavniki, ki lahko napovedujejo kakovost spanja.Every day, employees face workloads, consuming energy resources that must be compensated for during rest and quality sleep. In this master\u27s thesis, we conducted a diary study and examined the connections between different types of workloads (emotional, quantitative and cognitive), relaxation as an experience of rest and subjective sleep quality. The aim was also to examine how experiencing incivility at work predicts sleep quality and the possibility that relaxation mediates the relationship between the two constructs. The study involved 45 employees who completed diary questionnaires three times a day for six consecutive days. Multilevel modeling allows for the study of more complex connections. The results of the mediation analyses showed that relaxation is not a significant mediator in the relationship between workloads and subjective sleep quality, nor between incivility at work and sleep quality on a daily basis. A direct effect was found only for emotional workload, which statistically significantly negatively predicts sleep on a daily basis. We found that workplace incivility was a statistically significant negative predictor of relaxation. The results provide important insights into the associations between workload and incivility on employees\u27 sleep quality and the role of relaxation as a potential mediator in daily relationships. The results encourage further research with larger samples and different mediators and factors that can predict sleep quality
The effect of the SAFE or SORRY? programme on patient safety knowledge of nurses in hospitals and nursing homes: a cluster randomised trial
No full textBackground: patients in hospitals and nursing homes are at risk for the development of often preventable adverse events. Guidelines for the prevention of many types of adverse events are available, however compliance with these guidelines appears to be lacking. As a result many patients do not receive appropriate care. We developed a patient safety program that allows organisations to implement multiple guidelines simultaneously and therefore facilitates guideline use to improve patient safety. This program was developed for three frequently occurring nursing care related adverse events: pressure ulcers, urinary tract infections and falls. For the implementation of this program we developed educational activities for nurses as a main implementation strategy.Objectives: the aim of this study is to describe the effect of interactive and tailored education on the knowledge levels of nurses.Design: a cluster randomised trial was conducted between September 2006 and July 2008.Settings: ten hospital wards and ten nursing home wards participated in this study. Prior to baseline, randomisation of the wards to an intervention or control group was stratified for centre and type of ward.Participants: all nurses from participating wards.Methods: a knowledge test measured nurses’ knowledge on the prevention of pressure ulcers, urinary tract infections and falls, during baseline en follow-up. The results were analysed for hospitals and nursing homes separately.Results: after correction for baseline, the mean difference between the intervention and the control group on hospital nurses’ knowledge on the prevention of the three adverse events was 0.19 points on a zero to ten scale (95% CI: ?0.03 to 0.42), in favour of the intervention group. There was a statistically significant effect on knowledge of pressure ulcers, with an improved mean mark of 0.45 points (95% CI: 0.10–0.81). For the other two topics there was no statistically significant effect. Nursing home nurses’ knowledge did neither improve (0 points, CI: ?0.35 to 0.35) overall, nor for the separate subjects.Conclusion: the educational intervention improved hospital nurses’ knowledge on the prevention of pressure ulcers only. More research on long term improvement of knowledge is neede

Heterogeneous and tissue-specific regulation of effector T cell responses by IFN-gamma during Plasmodium berghei ANKA infection.
No full textIFN-γ and T cells are both required for the development of experimental cerebral malaria during Plasmodium berghei ANKA infection. Surprisingly, however, the role of IFN-γ in shaping the effector CD4(+) and CD8(+) T cell response during this infection has not been examined in detail. To address this, we have compared the effector T cell responses in wild-type and IFN-γ(-/-) mice during P. berghei ANKA infection. The expansion of splenic CD4(+) and CD8(+) T cells during P. berghei ANKA infection was unaffected by the absence of IFN-γ, but the contraction phase of the T cell response was significantly attenuated. Splenic T cell activation and effector function were essentially normal in IFN-γ(-/-) mice; however, the migration to, and accumulation of, effector CD4(+) and CD8(+) T cells in the lung, liver, and brain was altered in IFN-γ(-/-) mice. Interestingly, activation and accumulation of T cells in various nonlymphoid organs was differently affected by lack of IFN-γ, suggesting that IFN-γ influences T cell effector function to varying levels in different anatomical locations. Importantly, control of splenic T cell numbers during P. berghei ANKA infection depended on active IFN-γ-dependent environmental signals--leading to T cell apoptosis--rather than upon intrinsic alterations in T cell programming. To our knowledge, this is the first study to fully investigate the role of IFN-γ in modulating T cell function during P. berghei ANKA infection and reveals that IFN-γ is required for efficient contraction of the pool of activated T cells
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Measuring industry-science links through inventor-author relations: A profiling method
No full textIn this pilot study we examine the performance of text-based profiling in recovering a set of validated inventor-author links. In a first step we match patents and publications solely based on their similarity in content. Next, we compare inventor and author names on the highest ranked matches for the occurrence of name matches. Finally, we compare these candidate matches with the names listed in a validated set of inventor-author names. Our text-based profile methodology performs significantly better than a random matching of patents and publications, suggesting that text-based profiling is a valuable complementary tool to the name searches used in previous studies.innovation; industry-science links; text-based profiling;
Electronic structure of (1 1 3)-grown GaAs-(GaAl)As single quantum wells under biaxial strain fields.
No full textInternational audienceOptical properties of (1 1 3)-grown GaAs-(GaAl)As single quantum wells (SQW's) have been studied by wavelength- and piezomodulated spectroscopy. A supermodulation of light hole states is observed in piezomodulation spectroscopy. The theoretical methods required to compute the envelope functions and the stress dependence of the transition energies are detailed. A close agreement is obtained between the experimental observations and the theoretical predictions
