Validation of the German version of the Career Adapt-Abilities Scale and its relation to orientations to happiness and work stress

Career adapt-ability has recently gained momentum as a psychosocial construct that not only has much to offer the field of career development, but also contributes to positive coping, adjustment and self-regulation through the four dimensions of concern, control, curiosity and confidence. The positive psychology movement, with concepts such as the orientations to happiness, explores the factors that contribute to human flourishing and optimum functioning. This research has two main contributions; 1) to validate a German version of the Career Adapt-Abilities Scale (CAAS), and 2) to extend the contribution of adapt-abilities to the field of work stress and explore its mediating capacity in the relation between orientations to happiness and work stress. We used a representative sample of the German-speaking Swiss working population including 1204 participants (49.8% women), aged between 26 and 56 (Mage = 42.04). Results indicated that the German version of the CAAS is valid, with overall high levels of model fit suggesting that the conceptual structure of career adapt-ability replicates well in this cultural context. Adapt-abilities showed a negative relationship to work stress, and a positive one with orientations to happiness. The engagement and pleasure scales of orientations to happiness also correlated negatively with work stress. Moreover, career adapt-ability mediates the relationship between orientations to happiness and work stress. In depth analysis of the mediating effect revealed that control is the only significant mediator. Thus control may be acting as a mechanism through which individuals attain their desired life at work subsequently contributing to reduced stress levels.

Medical aspects of helicopter rescue missions involving winching of a physician

Introduction: Whereas the use of helicopters as a rapid means toreach victims and to bring them to a secure place is well-recognized,very few data are available about the value of winching physicians toprovide medical care for the victims directly on-site. We sought to studythe medical aspects of alpine helicopter rescue operations involving thewinching of an emergency physician to the victim.Methods: We retrospectively reviewed the medical reports of a singlehelicopter-based emergency medical service. Data from 1 January 2003to 31 December 2008 were analyzed. Cases with emergency callindicating that the victim was deceased were excluded. Data includedthe category (trauma or illnesses), and severity (NACA score) of theinjuries, along with the main medical procedures performed on site.Results: 9879 rescue missions were conducted between 1 January2003 and 31 December 2008. The 921 (9.3%) missions involvingwinching of the emergency physician were analysed. 840 (91%)patients suffered from trauma-related injuries. The cases of the 81 (9%)people presenting with medical emergencies were, when compared tothe trauma victims, significantly more severe according to the NACAindex (p <0.001). Overall, 246 (27%) patients had a severe injury orillness, namely, a potential or overt vital threat (NACA score between4-6, table 1). A total of 478 (52%) patients required administration ofmajor analgesics: fentanyl (443 patients; 48%), ketamine (42 patients;5%) or morphine (7 patients; 1%). The mean dose of fentanyl was 188micrograms (range 25-750, SD 127). Major medical interventions wereperformed 72 times on 39 (4%) patients (table 2).Conclusions: The severity of the patients' injuries or illnesses alongwith the high proportion of medical procedures performed directlyon-site validate emergency physician winching for advanced life supportprocedures and analgesia.

The impact of past direct-personal traumatic events on 12-month outcome in first episode psychotic mania: trauma and early psychotic mania.

OBJECTIVE: Past traumatic events have been associated with poorer clinical outcomes in people with bipolar disorder. However, the impact of these events in the early stages of the illness remains unclear. The aim of this study was to investigate whether prior traumatic events were related to poorer outcomes 12 months following a first episode of psychotic mania. METHODS: Traumatic events were retrospectively evaluated from patient files in a sample of 65 participants who had experienced first episode psychotic mania. Participants were aged between 15 and 28 years and were treated at a specialised early psychosis service. Clinical outcomes were measured by a variety of symptomatic and functioning scales at the 12-month time-point. RESULTS: Direct-personal traumatic experiences prior to the onset of psychotic mania were reported by 48% of the sample. Participants with past direct-personal trauma had significantly higher symptoms of mania (p=0.02), depression (p=0.03) and psychopathology (p=0.01) 12 months following their first episode compared to participants without past direct-personal trauma, with medium to large effects observed. After adjusting for baseline scores, differences in global functioning (as measured by the Global Assessment of Functioning scale) were non-significant (p=0.05); however, participants with past direct-personal trauma had significantly poorer social and occupational functioning (p=0.04) at the 12-month assessment with medium effect. CONCLUSIONS: Past direct-personal trauma may predict poorer symptomatic and functional outcomes after first episode psychotic mania. Limitations include that the findings represent individuals treated at a specialist early intervention centre for youth and the retrospective assessment of traumatic events may have been underestimated.

Social personality trait and fitness.

Several recent studies have explored various aspects of animal personality and their ecological consequences. However, the processes responsible for the maintenance of personality variability within a population are still largely unknown. We have recently demonstrated that social personality traits exist in the common lizard (Lacerta vivipara) and that the variation in sociability provides an explanation for variable dispersal responses within a given species. However, we need to know the fitness consequences of variation in sociability across environmental contexts in order to better understand the maintenance of such variation. In order to achieve this, we investigated the relationship between sociability and survival, body growth and fecundity, in one-year-old individuals in semi-natural populations with varying density. 'Asocial' and 'social' lizards displayed different fitness outcomes in populations of different densities. Asocial lizards survived better in low-density populations, while social females reproduced better. Spatiotemporal variation in environmental conditions might thus be the process underlying the maintenance of these personality traits within a population. Finally, we also discuss the position of sociability in a more general individual behavioural pattern including boldness, exploration and aggressiveness.

The Academic Work and Careers in Europe : Trends, Challenges, Perspectives

This book explores the perceptions of academic staff and representatives of institutional leadership about the changes in academic careers and academic work experienced in recent years. It emphasizes standardization and differentiation of academic career paths, impact of new forms of quality management on academic work, changes in recruitment, employment and working conditions, and academics' perceptions of their professional contexts. The book demonstrates a growing diversity within the academic profession and new professional roles inhabiting a space which is neither located in the core business of teaching and research nor at the top level management and leadership. The new higher education professionals tend to be important change agents within the higher education institutions not only fulfilling service and bridging functions but also streamlining academic work to make a contribution to the reputation and competitiveness of the institutions as a whole. Based on interviews with academic staff, this book explores the situation in eight European countries: Austria, Croatia, Finland, Germany, Ireland, Romania, and Switzerland.

Agent based simulation to optimise emergency departments

Nowadays, many of the health care systems are large and complex environments and quite dynamic, specifically Emergency Departments, EDs. It is opened and working 24 hours per day throughout the year with limited resources, whereas it is overcrowded. Thus, is mandatory to simulate EDs to improve qualitatively and quantitatively their performance. This improvement can be achieved modelling and simulating EDs using Agent-Based Model, ABM and optimising many different staff scenarios. This work optimises the staff configuration of an ED. In order to do optimisation, objective functions to minimise or maximise have to be set. One of those objective functions is to find the best or optimum staff configuration that minimise patient waiting time. The staff configuration comprises: doctors, triage nurses, and admissions, the amount and sort of them. Staff configuration is a combinatorial problem, that can take a lot of time to be solved. HPC is used to run the experiments, and encouraging results were obtained. However, even with the basic ED used in this work the search space is very large, thus, when the problem size increases, it is going to need more resources of processing in order to obtain results in an acceptable time.

Advanced trauma life support, 8th edition, the evidence for change.

The American College of Surgeons Committee on Trauma's Advanced Trauma Life Support Course is currently taught in 50 countries. The 8th edition has been revised following broad input by the International ATLS subcommittee. Graded levels of evidence were used to evaluate and approve changes to the course content. New materials related to principles of disaster management have been added. ATLS is a common language teaching one safe way of initial trauma assessment and management.

Frequent users of emergency departments present very high prevalence of mental health and substance use disorders, which are largely underdiagnosed by clinicians

Background: The objective of this study was to determine if mental health and substance use diagnoses were equally detected in frequent users (FUs) compared to infrequent users (IUs) of emergency departments (EDs). Methods: In a sample of 399 adult patients (>= 18 years old) admitted to a teaching hospital ED, we compared the mental health and substance use disorders diagnoses established clinically and consigned in the medical files by the ED physicians to data obtained in face-to-face research interviews using the Primary Care Evaluation of Mental Disorders (PRIME-MD) and the Alcohol, Smoking and Involvement Screening Test (ASSIST). Between November 2009 and June 2010, 226 FUs (>4 visits within a year) who attended the ED were included, and 173 IUs (<= 4 visits within a year) were randomly selected from a pool of identified patients to comprise the comparison group. Results: For mental health disorders identified by the PRIME-MD, FUs were more likely than IUs to have an anxiety (34 vs. 16%, Chi2(1) = 16.74, p <0.001), depressive (47 vs. 25%, Chi2(1) = 19.11, p <0.001) or posttraumatic stress (PTSD) disorder (11 vs. 5%, Chi2(1) = 4.87, p = 0.027). Only 3/76 FUs (4%) with an anxiety disorder, 16/104 FUs (15%) with a depressive disorder and none of the 24 FUs with PTSD were detected by the ED medical staff. None of the 27 IUs with an anxiety disorder, 6/43 IUs (14%) with a depressive disorder and none of the 8 IUs with PTSD were detected. For substance use disorders identified by the ASSIST, FUs were more at risk than IUs for alcohol (24 vs. 7%, Chi2(1) = 21.12, p <0.001) and drug abuse/dependence (36 vs. 25%, Chi2(1) = 5.52, p = 0.019). Of the FUs, 14/54 (26%) using alcohol and 8/81 (10%) using drugs were detected by the ED physicians. Of the IUs, 5/12 (41%) using alcohol and none of the 43 using drugs were detected. Overall, there was no significant difference in the rate of detection of mental health and substance use disorders between FUs and IUs (Fisher's Exact Test: anxiety, p = 0.567; depression, p = 1.000; PTSD, p = 1.000; alcohol, p = 0.517; and drugs, p = 0.053). Conclusions: While the prevalence of mental health and substance use disorders was higher among FUs, the rates of detection were not significantly different for FUs vs. IUs. However, it may be that drug disorders among FUs were more likely to be detected.

Effects of genetic alterations in arbuscular mycorrhizal fungi on plant growth and on their response to a change of host

Abstract :The majority of land plants form the symbiosis with arbuscular mycorrhizal fungi (AMF). The AM symbiosis has existed for hundreds of millions of years but little or no specificity seems to have co- evolved between the partners and only about 200 morphospecies of AMF are known. The fungi supply the plants most notably with phosphate in exchange for carbohydrates. The fungi improve plant growth, protect them against pathogens and herbivores and the symbiosis plays a key role in ecosystem productivity and plant diversity. The fungi are coenocytic, grow clonally and no sexual stage in their life cycle is known. For these reasons, they are presumed ancient asexuals. Evidence suggests that AMF contain populations of genetically different nucleotypes coexisting in a common cytoplasm. Consequently, the nucleotype content of new clonal offspring could potentially be altered by segregation of nuclei at spore formation and by genetic exchange between different AMF. Given the importance of AMF, it is surprising that remarkably little is known about the genetics and genomics of the fungi.The main goal of this thesis was to investigate the combined effects of plant species differences and of genetic exchange and segregation in AMF on the symbiosis. This work showed that single spore progeny can receive a different assortment of nucleotypes compared to their parent and compared to other single spore progeny. This is the first direct evidence that segregation occurs in AMF. We then showed that both genetic exchange and segregation can lead to new progeny that differentially alter plant growth compared to their parents. We also found that genetic exchange and segregation can lead to different development of the fungus during the establishment of the symbiosis. Finally, we found that a shift of host species can differentially alter the phenotypes and genotypes of AMF progeny obtained by genetic exchange and segregation compared to their parents.Overall, this study confirms the multigenomic state of the AMF Glomus intraradices because our findings are possible only if the fungus contains genetically different nuclei. We demonstrated the importance of the processes of genetic exchange and segregation to produce, in a very short time span, new progeny with novel symbiotic effects. Moreover, our results suggest that different host species could affect the fate of different nucleotypes following genetic exchange and segregation in AMF, and can potentially contribute to the maintenance of genetic diversity within AMF individuals. This work brings new insights into understanding how plants and fungi have coevolved and how the genetic diversity in AMF can be maintained. We recommend that the intra-ir1dividual AMF diversity and these processes should be considered in future research on this symbiosis.Résumé :La majorité des plantes terrestres forment des symbioses avec les champignons endomycorhiziens arbusculaires (CEA). Cette symbiose existe depuis plusieurs centaines de millions d'années mais peu ou pas de spécificité semble avoir co-évoluée entre les partenaires et seulement 200 morpho-espèces de CEA sont connues. Le champignon fournit surtout aux plantes du phosphate en échange de carbohydrates. Le champignon augmente la croissance des plantes, les protège contre des pathogènes et herbivores et la symbiose joue un rôle clé dans la productivité des écosystèmes et de la diversité des plantes. Les CEA sont coenocytiques, se reproduisent clonalement et aucune étape sexuée n'est connue dans leur cycle de vie. Pour ces raisons, ils sont présumés comme anciens asexués. Des preuves suggèrent que les CEA ont des populations de nucleotypes différents coexistant dans un cytoplasme commun. Par conséquent, le contenu en nucleotype des nouveaux descendants clonaux pourrait être altéré par la ségrégation des noyaux lors de la fonnation des spores et par l'échange génétique entre différents CEA. Etant donné l'importance des CEA, il est surprenant que si peu soit connu sur la génétique et la génomique du champignon.Le principal but de cette thèse a été d'étudier les effets combinés de différentes espèces de plantes et des mécanismes d'échange génétique et de ségrégation chez les CEA sur la symbiose. Ce travail a montré que chaque nouvelle spore produite pouvait recevoir un assortiment différent de noyaux comparé au parent ou comparé à d'autres nouvelles spores. Ceci est la première preuve directe que la ségrégation peut se produire chez les CEA. Nous avons ensuite montré qu'à la fois l'échange génétique et la ségrégation pouvaient mener à de nouveaux descendants qui altèrent différemment la croissance des plantes, comparé à leurs parents. Nous avons également trouvé que l'échange génétique et la ségrégation pouvaient entraîner des développements différents du champignon pendant l'établissement de la symbiose. Pour finir, nous avons trouvé qu'un changement d'espèce de l'hôte pouvait altérer différemment les phénotypes et génotypes des descendants issus d'échange génétique et de ségrégation, comparé à leurs parents.Globalement, cette étude confirme l'état multigénomique du CEA Glumus intraradices car nous résultats sont possibles seulement si le champignon possède des noyaux génétiquement différents. Nous avons démontrés l'importance des mécanismes d'échange génétique et de ségrégation pour produire en très peu de temps de nouveaux descendants ayant des effets symbiotiques nouveaux. De plus, nos résultats suggèrent que différentes espèces de plantes peuvent agir sur le devenir des nucleotypes après l'échange génétique et la ségrégation chez les CEA, et pourraient contribuer à la maintenance de la diversité génétique au sein d'un même CEA. Ce travail apporte des éléments nouveaux pour comprendre comment les plantes et les champignons ont coévolué et comment la diversité génétique chez les CEA peut être maintenue. Nous recommandons de considérer la diversité génétique intra-individuelle des CEA et ces mécanismes lors de futures recherches sur cette symbiose.

Efficacité a court et moyen termes des traitements d'urgence-crise pour couples et families: résultats et perspectives [Short and medium-term effectiveness of the emergency-crisis treatments for couples and families: results and perspectives].

From 2007 to 2010, the emergency-crisis unit of the Couple and Family Consultation Unit -UCCF (West Psychiatric Service, Prangins Psychiatric Hospital, Psychiatric Department of CHUV) has carried out a research about the relevance and usefulness of emergency-crisis, systemic-oriented treatments, for deeply distressed couples and families. Besides epidemiologic data, we present results demonstrating the efficiency of those treatments, both at short-term and at a one year's range. The global impact of such treatments in terms of public health, but also economical issues, make us believe that they should be fully included in the new trend of psychiatric ambulatory care, into the social net.

High Growth Firms and Innovation: an empirical analysis for Spanish firms

This paper analyzes the effect of firms’ innovation activities on their growth performance. In particular, we observe how important innovation is for high-growth firms (HGFs) for an extensive sample of Spanish manufacturing and services firms. The panel data used comprises diverse waves of Spanish CIS over the the period 2004-2008. First, a probit analysis determines whether innovation affects the probability of being a high-growth firm. And second, a quantile regression technique is applied to explore the determinants and characteristics of specific groups of firms (manufacturing versus service firms and high-tech versus low-tech firms). It is revealed that R&D plays a significant role in the probability of becoming a HGF. Investment in internal and external R&D per employee has a positive impact on firm growth (although internal R&D presents a significant impact in the last quantiles, external R&D is significant up to the median). Furthermore, we show evidence that there is a positive impact of employment (sales) growth on the sales (employment) growth.
