Team reflexivity and innovation:the moderating role of team context

We developed and tested a team level contingency model of innovation, integrating theories regarding work demands, team reflexivity - the extent to which teams collectively reflect upon their working methods and functioning -, and team innovation. We argued that highly reflexive teams will be more innovative than teams low in reflexivity when facing a demanding work environment. The relationships between team reflexivity, a demanding work environment (i.e. quality of the physical work environment and work load) and team innovation was examined among 98 primary health care teams (PHCTs) in the UK, comprised of 1137 individuals. Results showed that team reflexivity is positively related to team innovation, and that there is an interaction between team reflexivity, team level workload, and team innovation, such that when team level workload is high, combined with a high level of team reflexivity, team innovation is also higher. The complementary interaction between team reflexivity, quality of physical work environment, and team innovation, showed that when the quality of the work environment is low, combined with a high level of team reflexivity, team innovation was also higher. These results are discussed in the context of the need for team reflexivity and team innovation among teams at work facing high work demands.

Spectral sensitivity, spatial resolution and temporal resolution and their implications for conspecific signalling in cleaner shrimp.

Cleaner shrimp (Decapoda) regularly interact with conspecifics and client reef fish, both of which appear colourful and finely patterned to human observers. However, whether cleaner shrimp can perceive the colour patterns of conspecifics and clients is unknown, because cleaner shrimp visual capabilities are unstudied. We quantified spectral sensitivity and temporal resolution using electroretinography (ERG), and spatial resolution using both morphological (inter-ommatidial angle) and behavioural (optomotor) methods in three cleaner shrimp species: Lysmata amboinensis, Ancylomenes pedersoni and Urocaridella antonbruunii. In all three species, we found strong evidence for only a single spectral sensitivity peak of (mean ± s.e.m.) 518 ± 5, 518 ± 2 and 533 ± 3 nm, respectively. Temporal resolution in dark-adapted eyes was 39 ± 1.3, 36 ± 0.6 and 34 ± 1.3 Hz. Spatial resolution was 9.9 ± 0.3, 8.3 ± 0.1 and 11 ± 0.5 deg, respectively, which is low compared with other compound eyes of similar size. Assuming monochromacy, we present approximations of cleaner shrimp perception of both conspecifics and clients, and show that cleaner shrimp visual capabilities are sufficient to detect the outlines of large stimuli, but not to detect the colour patterns of conspecifics or clients, even over short distances. Thus, conspecific viewers have probably not played a role in the evolution of cleaner shrimp appearance; rather, further studies should investigate whether cleaner shrimp colour patterns have evolved to be viewed by client reef fish, many of which possess tri- and tetra-chromatic colour vision and relatively high spatial acuity.

Simplified Predictive Instrument to Rule Out Acute Coronary Syndromes in a High-Risk Population.

BACKGROUND: It is unclear whether diagnostic protocols based on cardiac markers to identify low-risk chest pain patients suitable for early release from the emergency department can be applied to patients older than 65 years or with traditional cardiac risk factors. METHODS AND RESULTS: In a single-center retrospective study of 231 consecutive patients with high-risk factor burden in which a first cardiac troponin (cTn) level was measured in the emergency department and a second cTn sample was drawn 4 to 14 hours later, we compared the performance of a modified 2-Hour Accelerated Diagnostic Protocol to Assess Patients with Chest Pain Using Contemporary Troponins as the Only Biomarker (ADAPT) rule to a new risk classification scheme that identifies patients as low risk if they have no known coronary artery disease, a nonischemic electrocardiogram, and 2 cTn levels below the assay's limit of detection. Demographic and outcome data were abstracted through chart review. The median age of our population was 64 years, and 75% had Thrombosis In Myocardial Infarction risk score ≥2. Using our risk classification rule, 53 (23%) patients were low risk with a negative predictive value for 30-day cardiac events of 98%. Applying a modified ADAPT rule to our cohort, 18 (8%) patients were identified as low risk with a negative predictive value of 100%. In a sensitivity analysis, the negative predictive value of our risk algorithm did not change when we relied only on undetectable baseline cTn and eliminated the second cTn assessment. CONCLUSIONS: If confirmed in prospective studies, this less-restrictive risk classification strategy could be used to safely identify chest pain patients with more traditional cardiac risk factors for early emergency department release.

Estudio sobre la variación perfecto simple y perfecto compuesto en los discursos presidenciales de Evo Morales : Marcas del contacto lingüístico

El trabajo presenta un análisis cualitativo-cuantitativo del uso variable del perfecto simple y perfecto compuesto en los discursos presidenciales de Evo Morales, de acuerdo con la perspectiva Etnopragmática desarrollada por García 1990, 1995; Martínez 1995, 2000; Mauder 2000. Se considera la singularidad de una variedad en situación de contacto lingüístico: la del español en contacto con el aymara y el quechua, y se indaga sobre las transformaciones que pueden producirse cuando diferentes lenguas -diferentes visiones de mundo- entran en contacto. En relación con esto, veremos que la presencia, tanto en la lengua quechua como en la lengua aymara, de un sistema evidencial gramaticalizado podría influir en la variación del perfecto simple y compuesto en los discursos de Morales, en particular, que la presencia de la forma del perfecto compuesto podría funcionar como una marca de evidencia directa y su uso contribuiría a la estrategia discursiva del orador de mostrar ciertos hechos de la historia de Bolivia como cercanos a su vivencia y experiencia personales, marcando un mayor grado compromiso con respecto a la veracidad de lo que enuncia. De esta manera, el orador consigue aunar su voz con la de los pueblos originarios, formar parte de los grupos discriminados y excluidos de la historia de su país y así, contar con su apoyo y acompañamiento durante su mandato.

Physical oceanography, pore water chemistry and water column methane turover rates during POLARSTERN cruise ANT-XXIX/4

Recent studies have suggested that the marine contribution of methane from shallow regions and melting marine terminating glaciers may have been underestimated. Here we report on methane sources and potential sinks associated with methane seeps in Cumberland Bay, South Georgia's largest fjord system. The average organic carbon content in the upper 8 meters of the sediment is around 0.65 wt.%; this observation combined with Parasound data suggest that the methane gas accumulations probably originate from peat-bearing sediments currently located several tens of meters below the seafloor. Only one of our cores indicates upward advection; instead most of the methane is transported via diffusion. Sulfate and methane flux estimates indicate that a large fraction of methane is consumed by anaerobic oxidation of methane (AOM). Carbon cycling at the sulfate-methane transition (SMT) results in a marked fractionation of the d13C-CH4 from an estimated source value of -65 per mil to a value as low as -96 per mil just below the SMT. Methane concentrations in sediments are high, especially close to the seepage sites (~40 mM); however, concentrations in the water column are relatively low (max. 58 nM) and can be observed only close to the seafloor. Methane is trapped in the lowermost water mass, however, measured microbial oxidation rates reveal very low activity with an average turnover of 3.1 years. We therefore infer that methane must be transported out of the bay in the bottom water layer. A mean sea-air flux of only 0.005 nM/m²/s confirms that almost no methane reaches the atmosphere.

The relationship between changes in cardiovascular function and changes in VO2peak following SIT

Background: It is well known that sprint interval training (SIT), induces significant increases in peak oxygen uptake (VO2peak) at the group level. However, there have been only a few studies that have addressed the variability of VO2peak response following SIT, and precise mechanism(s) that may explain individual magnitude of response are unknown. Purpose: Therefore, the purpose of this thesis was to: 1) examine the inter-individual variability of the VO2peak response following SIT, 2) to inspect the relationship between changes in both central and peripheral measures and changes in VO2peak, and 3) to assess if peripheral or central adaptations play a role in whether an individual is a high or low responder with respect to VO2peak. Subjects: Twenty-two young, recreationally active males (age: 20.4 1.7 years; weight: 78.4 10.2 kg; VO2peak: 3.7 0.62 L/min) Methods: VO2peak (L/min), peak cardiac output (Qpeak [L/min]), and peak deoxygenated hemoglobin (HHbpeak [mM]) were measured before and after 16 sessions of SIT (Tabata Protocol) over four weeks. Peak a-vO2diff was calculated using a derivation of the Fick equation. Results: Due to a systematic error, HHbpeak could not be used to differentiate between individual responses. There was a large range of VO2peak response from pre to post testing (-4.75 to 32.18% change) and there was a significant difference between the Low Response Group (LRG) (n=8) and the High Response Group (HRG) (n=8) [f(1, 14)= 64.27, p<0.001]. Furthermore, there was no correlation between delta () VO2peak and Qpeak (r=-0.18, p=0.46) for all participants, nor was there an interaction effect between the Low and High Response Groups [f(1,11)=0.572, p=0.47]. Lastly, there was a significant correlation between VO2peak and peak a-vO2diff [r=0.692, p<0.001], and a significant interaction effect with peak a-vO2diff [f(1, 14)= 13.27, p<0.004] when comparing the HRG to the LRG. Conclusions: There was inter-individual variability of VO2peak response following 4 weeks of SIT, but central adaptations did not influence this variation. This suggests that peripheral adaptations may be responsible for VO2peak adaptation.

Espaço Mudança

O “Espaço de Mudança”, projecto gerido pela Santa Casa da Misericórdia do Concelho de Oliveira do Bairro, tem um Programa de Educação Parental (PEP) que funciona por encaminhamento e sinalização de entidades deste Concelho. Neste sentido, o PEP é construído de forma a responder às características e especificidades da população-alvo que atende, não se baseando em nenhum programa- -modelo. Por este motivo, o presente estudo constituiu-se num estudo de caso com o objectivo de avaliar se o PEP está a responder aos fins para os quais foi construído. Neste sentido, incorpora a caracterização e avaliação familiar de cada participante, a avaliação do seu desempenho no decorrer das sessões, a análise de mudanças significativas ao nível das variáveis adaptabilidade e coesão familiar, recursos familiares, coping familiar e suporte social, e também a análise de mudanças nas dificuldades e/ou nos problemas identificados na sinalização. Através deste estudo foi possível verificar que as mulheres participantes do PEP constituem um grupo com baixas qualificações, com percursos de pobreza, sendo beneficiárias da prestação de Rendimento Social de Inserção (RSI), e com problemáticas que se encadeiam e influenciam várias áreas das suas vidas. Contudo, constituem-se num grupo heterogéneo a nível de competências e necessidades. Tidas no seu conjunto, podemos concluir que 4 das 5 participantes tiveram um bom desempenho, concluindo-se que o PEP foi adequado para esta maioria Ao nível das variáveis adaptabilidade e coesão familiar, recursos familiares, coping familiar e suporte social não foram identificadas diferenças estatisticamente significativas ao longo do programa, porém é de realçar que, de forma global, as participantes melhoraram os seus resultados. É ainda possível verificar que o PEP teve um impacte positivo nas mesmas 4 formandas, as quais conseguiram ultrapassar algumas das dificuldades e/ou problemas que motivaram o encaminhamento. Foi possível concluir que o facto de se tratar de um grupo heterogéneo veio trazer ganhos para as participantes, contudo um dos elementos, que tinha uma problemática associada ao alcoolismo, deveria ter sido integrado num grupo com características diferentes, razão pela qual o PEP não se constituiu como uma resposta adequada para este elemento. O estudo revela ainda que o PEP no Espaço Mudança constitui uma mais-valia para colaborar na activação das competências pessoais, sociais e parentais das mães que passam por dificuldades acrescidas, sendo de promover e potenciar este tipo de intervenções construídas a partir das características e necessidades da população-alvo. /

Développement d’un questionnaire cognitif bref, le FaCE (The Fast Cognitive Evaluation), selon la modélisation Rasch adapté aux patients avec cancer

Les déficits cognitifs sont présents chez les patients atteints de cancer. Les tests cognitifs tels que le Montreal Cognitive Assessment se sont révélés peu spécifiques, incapables de détecter des déficits légers et ne sont pas linéaires. Pour suppléer à ces limitations nous avons développé un questionnaire cognitif simple, bref et adapté aux dimensions cognitives atteintes chez les patients avec un cancer, le FaCE « The Fast Cognitif Evaluation », en utilisant la modélisation Rasch (MR). La MR est une méthode mathématique probabiliste qui détermine les conditions pour qu’un outil soit considéré une échelle de mesure et elle est indépendante de l’échantillon. Si les résultats s’ajustent au modèle, l’échelle de mesure est linéaire avec des intervalles égaux. Les réponses sont basées sur la capacité des sujets et la difficulté des items. La carte des items permet de sélectionner les items les plus adaptés pour l’évaluation de chaque aspect cognitif et d’en réduire le nombre au minimum. L’analyse de l’unidimensionnalité évalue si l’outil mesure une autre dimension que celle attendue. Les résultats d’analyses, conduites sur 165 patients, montrent que le FaCE distingue avec une excellente fiabilité et des niveaux suffisamment différents les compétences des patients (person-reliability-index=0.86; person-separation-index=2.51). La taille de la population et le nombre d’items sont suffisants pour que les items aient une hiérarchisation fiable et précise (item-reliability=0.99; item-séparation-index=8.75). La carte des items montre une bonne dispersion de ceux-ci et une linéarité du score sans effet plafond. Enfin, l’unidimensionnalité est respectée et le temps d’accomplissement moyen est d’environ 6 minutes. Par définition la MR permet d’assurer la linéarité et la continuité de l’échelle de mesure. Nous avons réussi à développer un questionnaire bref, simple, rapide et adapté aux déficits cognitifs des patients avec un cancer. Le FaCE pourrait, aussi, servir de mesure de référence pour les futures recherches dans le domaine.
