Affective word priming in the left and right visual fields in young and older individuals

Alors que les hypothèses de valence et de dominance hémisphérique droite ont longtemps été utilisées afin d’expliquer les résultats de recherches portant sur le traitement émotionnel de stimuli verbaux et non-verbaux, la littérature sur le traitement de mots émotionnels est généralement en désaccord avec ces deux hypothèses et semble converger vers celle du décours temporel. Cette dernière hypothèse stipule que le décours temporal lors du traitement de certains aspects du système sémantique est plus lent pour l’hémisphère droit que pour l’hémisphère gauche. L’objectif de cette thèse est d’examiner la façon dont les mots émotionnels sont traités par les hémisphères cérébraux chez des individus jeunes et âgés. À cet effet, la première étude a pour objectif d’évaluer l’hypothèse du décours temporel en examinant les patrons d’activations relatif au traitement de mots émotionnels par les hémisphères gauche et droit en utilisant un paradigme d’amorçage sémantique et une tâche d’évaluation. En accord avec l’hypothèse du décours temporel, les résultats obtenus pour les hommes montrent que l’amorçage débute plus tôt dans l’hémisphère gauche et plus tard dans l’hémisphère droit. Par contre, les résultats obtenus pour les femmes sont plutôt en accord avec l’hypothèse de valence, car les mots à valence positive sont principalement amorcés dans l’hémisphère gauche, alors que les mots à valence négative sont principalement amorcés dans l’hémisphère droit. Puisque les femmes sont considérées plus « émotives » que les hommes, les résultats ainsi obtenus peuvent être la conséquence des effets de la tâche, qui exige une décision explicite au sujet de la cible. La deuxième étude a pour objectif d’examiner la possibilité que la préservation avec l’âge de l’habileté à traiter des mots émotionnels s’exprime par un phénomène compensatoire d’activations bilatérales fréquemment observées chez des individus âgés et maintenant un haut niveau de performance, ce qui est également connu sous le terme de phénomène HAROLD (Hemispheric Asymmetry Reduction in OLDer adults). En comparant les patrons d’amorçages de mots émotionnels auprès de jeunes adultes et d’adultes âgés performants à des niveaux élevés sur le plan comportemental, les résultats révèlent que l’amorçage se manifeste unilatéralement chez les jeunes participants et bilatéralement chez les participants âgés. Par ailleurs, l’amorçage se produit chez les participants âgés avec un léger délai, ce qui peut résulter d’une augmentation des seuils sensoriels chez les participants âgés, qui nécessiteraient alors davantage de temps pour encoder les stimuli et entamer l’activation à travers le réseau sémantique. Ainsi, la performance équivalente au niveau de la précision retrouvée chez les deux groupes de participants et l’amorçage bilatéral observé chez les participants âgés sont en accord avec l’hypothèse de compensation du phénomène HAROLD.

State-dependent volume isotope shifts of low-lying states of group-IIa and -IIb elements

Results of relativistic multiconfiguration Dirac-Fock calculations with an extended nucleus are used to analyze the volume isotope shifts of the resonance transitions in the group-IIa and -IIb elements as well as in Yb. This is done together with a review of the isotope shift theory, including a critical evaluation and comparison of the semiempirical calculation of volume isotope shifts commonly used today. Electronic factors F_i, proportional to differences of electronic densities over the nuclear volume, are discussed within various approximations and compared with experimental results.

Ermittlung geeigneter Methoden zur Differenzierung und Qualitätsbeurteilung unterschiedlicher Milchqualitäten aus verschiedenen on-farm-Experimenten

Zusammenfassung: Ziel der Arbeit war ein Methodenvergleich zur Beurteilung der Milchqualität unterschiedlicher Herkünfte. Am Beispiel von Milchproben aus unterschiedlicher Fütterung sowie an Milchproben von enthornten bzw. horntragenden Kühen wurde geprüft, welche der angewendeten Methoden geeignet ist, die Vergleichsproben zu unterscheiden (Differenzierungsfähigkeit der Methoden) und inwieweit eine Qualitätsbeurteilung möglich ist (hinsichtlich Milchleistung, Fett-, Eiweiß-, Lactose- (=F,E,L), Harnstoff-gehalt und Zellzahl (=SCC), Säuerungseigenschaften (=SE), Fettsäuremuster (=FS-Muster), Protein- und Metabolit-Zusammensetzung (=Pr&M), Fluoreszenz-Anregungs-Spektroskopie-Eigenschaften (=FAS) und Steigbild-Merkmalen). Zusätzlich wurde vorab die Steigbildmethode (=SB-M) für das Produkt Rohmilch standardisiert und charakterisiert, um die Reproduzierbarkei der Ergebnisse sicherzustellen. Die Untersuchungen zur SB-M zeigten, dass es Faktoren gibt, die einen deutlichen Einfluß auf die Bildmerkmals-Ausprägung aufweisen. Dazu gehören laborseitig die Klimabedingungen in der Kammer, die Verdünnungsstufe der Probe, die Standzeiten der Vorverdünnung (Reaktionen mit der Luft, Alterung usw.), und tagesspezifisch auftretende Effekte, deren Ursache unbekannt ist. Probenseitig sind sehr starke tierindividuelle Effekte auf die Bildmerkmals-Ausprägung festzustellen, die unabhängig von Fütterung, Alter, Laktationsstadium und Genetik auftreten, aber auch Fütterungsbedingungen der Kühe lassen sich in der Bildmerkmals-Ausprägung wiederfinden. Die Art der Bildauswertung und die dabei berücksichtigten Bildmerkmale ist von großer Bedeutung für das Ergebnis. Die im Rahmen dieser Arbeit untersuchten 46 Probenpaare (aus den Fütterungsvergleichen (=FV) und zur Thematik der Hörner) konnten in 91% der Fälle korrekt gruppiert werden. Die Unterschiede konnten benannt werden. Drei FV wurden auf drei biologisch-dynamischen Höfen unter Praxis-Bedingungen durchgeführt (on-farm-Experimente). Es wurden jeweils zwei vergleichbare Gruppen à mindestens 11 Kühen gebildet, die im Cross-Over-Design gefüttert wurden, mit Probennahme am 14. und 21. Tag je Periode. Es wurden folgende FV untersucht: A: Wiesenheu vs. Kleegrasheu (=KG-Heu), B: Futterrüben (=FuR) vs. Weizen (Ergänzung zu Luzernegrasheu ad lib.), C: Grassilage vs. Grasheu. Bei Versuch A sind die Futtereffekte am deutlichsten, Gruppeneffekte sind gering. Die Milch der Wiesenheu-Variante hat weniger CLA’s und n3- FS und mehr mittellangkettige FS (MCT-FS), das Pr&M-Muster weist auf „Gewebereifung und Ausdifferenzierung“ vs. bei KG-Heu „Nährstoff-fülle, Wachstum und Substanz-Einlagerung und die SB zeigen fein ausdifferenzierte Bildmerkmale. Bei Versuch B sind die Futtereffekte ähnlich groß wie die Gruppeneffekte. Bei vergleichbarer Milchleistung weist die Milch der FuR-Variante höhere F- und E-Gehalte auf, sie säuert schneller und mehr, das FS-Muster weist auf eine „intensive“ Fütterung mit vermehrt MCT- FS, und die Pr&M-Untersuchungen charakterisieren sie mit „Eisentransport und Fetttröpfchenbildung“ vs. bei Weizen „mehr Abwehr-, Regulations- und Transportfunktion“ /. „mehr Lipidsynthese“. Die SB charakterisieren mit „große, kräftige Formen, verwaschen“ vs. „kleine, ausdifferenzierte Bildmerkmal“ für FuR vs. Weizen. Die FAS charakterisiert sie mit „Saftfutter-typisch“ vs. „Samentypisch“. Versuch C weist die geringsten Futtereffekt auf, und deutliche Gruppen- und Zeiteffekte. Milchleistung und F,E,L-Gehalte zeigen keinen Futtereffekt. Die Milch der Heu-Variante säuert schneller, und sie weist mehr SCT und MCT- FS auf. Pr&M-Untersuchungen wurden nicht durchgeführt. Die SB charakterisieren bei Heumilch mit „fein, zart, durchgestaltet, hell“, bei Silagemilch mit „kräftig, wäßrig-verwaschen, dunkler“. Die FAS kann keine konsistenten Unterschiede ermitteln. Der Horn-Einfluß auf die Milchprobe wurde an 34 Probenpaaren untersucht. Von 11 Höfen wurden je zwei möglichst vergleichbare Gruppen zusammengestellt, die sich nur im Faktor „Horn“ unterscheiden, und im wöchentlichen Abstand drei mal beprobt. F,E,L, SCC und SE der Proben sowie die FAS-Messungen weisen keine konsistenten signifikanten Unterschiede zwischen den Horn-Varianten auf. Pr&M weisen bei den untersuchten Proben (von zwei Höfen) auf Horneffekte hin: bei Eh eine Erhöhung von Immun-Abwehr-Funktionen, sowie einer Abnahme phosphorylierter C3- und C6-Metabolite und Beta-Lactoglobulin. Mit den SB ließen sich für die gewählten Merkmale (S-Größe und g.B.-Intensität) keine Horneffekte feststellen. FS, Pr&M-Muster sowie Harnstoffgehalt und SB (und z.T. Milchleistung) zeigten je FV ähnliche Effekt-Intensitäten für Futter-, Gruppen- und Zeiteffekte, und konnten die Cross-Over-Effekte gut wiedergeben. F- und E-Gehalte konnten neben tierindividuellen Effekten nur in FV B auch Futtereffekte aufzeigen. In FV C zeigten die SE der Proben den deutlichsten Futtereffekt, die anderen Methoden zeigten hier vorrangig Gruppen-Effekte, gefolgt von Futter- und Zeiteffekten. Die FAS zeigte den SB vergleichbare Ergebnisse, jedoch weniger sensibel reagierend. Die Interpretation von Qualitätsaspekten war bei konsistent differenzierbaren Proben (FV A, B, C) am fundiertesten mit Hilfe der FS möglich, da über die Synthese von FS und beeinflussende Faktoren schon vielfältige Erkenntnisse vorliegen. Das Pr&M-Muster war nach einer weiteren Methodenentwicklung bei der Deutung von Stoffwechselprozessen sehr hilfreich. Die FAS konnte z.T. eine zu der Fütterungsvariante passende Charakterisierung liefern. Für die SB-M fehlt es noch an Referenzmaterial, um Angaben zu Qualitätsaspekten zu machen, wenngleich Probenunterschiede aufgezeigt und Proben-Eigenschaften charakterisiert werden konnten.

Prevalencia de obesidad y factores de riesgo cardiovascular en estudiantes de ciencias de la salud - universidad del Quindío - 2013

ANTECEDENTES: En Colombia, reportes del año 2010 de la Encuesta Nacional de la Situación en Nutrición ENSIN 2010(2), muestran uno de cada dos colombianos, presentan un índice de masa corporal mayor al esperado (3) METODO: El presente estudio de corte transversal, determino la prevalencia de obesidad y otros factores de riesgo cardiovascular en una población de estudiantes de Ciencias de la Salud de una Universidad regional en el primer periodo académico del año 2013. El tamaño de muestra fue n=113 sujetos que corresponden 60,5% a la carrera de medicina y 39,95% a enfermería. Con el fin de conocer su comportamiento con respecto a hábitos y estilos de vida específicos como el consumo de alcohol, el consumo de tabaco y el sedentarismo, así como su asociación a eventos inflamatorios relacionados con la fisiopatología de los procesos de salud asociados al peso, por medio de instrumentos de medición clínica, antropométrica y sérica, determino un modelo estadístico propicio para entender el comportamiento de la obesidad y la enfermedad Cardiovascular RESULTADOS: La prevalencia estimada de sobrepeso y obesidad por Índice de Masa Corporal (IMC), fue del 27,7% (IC 95%: 19.9%,37.2%); por el perímetro abdominal (OBPABD) se encontró una prevalencia estimada del 27,4% (IC 95%: 19,9% – 36,4%), y la prevalencia con el Índice Cintura Cadera (OBICC) fue de 3,5% (IC 95%:1,3% – 9,3%). CONCLUSIONES: La presencia de hábitos no saludables y la presencia de sobrepeso y obesidad se considera que es necesario en primera instancia una valoración general de estado nutricional de los universitarios de las diferentes facultados y plantear estrategias preventivas ya que la literatura documenta los efectos de los hábitos no saludables sino además documenta los efectos de la prevención de la misma ya que en si se ha encontrado asociación para enfermedades cardiovasculares. Se propone que para obtener mayor información del comportamiento de los factores de riesgo cardiovasculares se deberían realizar estudios retrospectivos en el que intervengan las demás carreras de la universidad y poder evaluar la totalidad de población universitaria

Medical Evaluation Processes in Clinical settings. Qualitative Analysis through the Experience of Teachers and Studens

Evaluation processes in clinical practice have not been well, being their study focused on the technical issues concerning these processes. This study tried an approach to the evaluation processes through the analysis of perceptions from teachers and students about the methodology of evaluation considering the teachinglearning processes performed in a clinical practice of the Medicine Program –Universidad El Bosque from Bogota. With this purpose we conducted interviews with teachers and students searching the manner in which the evaluative, learning and teaching processes are done; then we analyzed the perception from both agents concerning the way these processes are related. The interviews were categorized bath deductively and inductively, and then contrasted with some current theories of learning, teaching and evaluation in medicine. The study showed that nowadays the evaluation and, in general, the educative processes are affected by several factors which are associated to the manner the professional practice is developed, and the educative process of the current teachers. We concluded there is no congrency between the approach of the evaluation, mainly conductivist, and the learning and teaching strategies mainly constructivist. This fact cause dissent in teachers and students.

Catalase in fluvial biofilms: a comparison between different extraction methods and example of application in a metal-polluted river

Antioxidant enzymes are involved in important processes of cell detoxification during oxidative stress and have, therefore, been used as biomarkers in algae. Nevertheless, their limited use in fluvial biofilms may be due to the complexity of such communities. Here, a comparison between different extraction methods was performed to obtain a reliable method for catalase extraction from fluvial biofilms. Homogenization followed by glass bead disruption appeared to be the best compromise for catalase extraction. This method was then applied to a field study in a metal-polluted stream (Riou Mort, France). The most polluted sites were characterized by a catalase activity 4–6 times lower than in the low-polluted site. Results of the comparison process and its application are promising for the use of catalase activity as an early warning biomarker of toxicity using biofilms in the laboratory and in the field

Interpretation of ambiguity in children: a prospective study of associations with anxiety and parental interpretations

Interpretation of ambiguity is consistently associated with anxiety in children, however, the temporal relationship between interpretation and anxiety remains unclear as do the developmental origins of interpretative biases. This study set out to test a model of the development of interpretative biases in a prospective study of 110 children aged 5–9 years of age. Children and their parents were assessed three times, annually, on measures of anxiety and interpretation of ambiguous scenarios (including, for parents, both their own interpretations and their expectations regarding their child). Three models were constructed to assess associations between parent and child anxiety and threat and distress cognitions and expectancies. The three models were all a reasonable fit of the data, and supported conclusions that: (i) children’s threat and distress cognitions were stable over time and were significantly associated with anxiety, (ii) parents’ threat and distress cognitions and expectancies significantly predicted child threat cognitions at some time points, and (iii) parental anxiety significantly predicted parents cognitions, which predicted parental expectancies at some time points. Parental expectancies were also significantly predicted by child cognitions. The findings varied depending on assessment time point and whether threat or distress cognitions were being considered. The findings support the notion that child and parent cognitive processes, in particular parental expectations, may be a useful target in the treatment or prevention of anxiety disorders in children.

Divergent evolutionary pattern of starch biosynthetic pathway genes in grasses and dicots

Starch is the most widespread and abundant storage carbohydrate in crops and its production is critical to both crop yield and quality. As regards the starch content in the seeds of crop plants, there are distinct difference between grasses (Poaceae) and dicots. However, few studies have described the evolutionary pattern of genes in the starch biosynthetic pathway in these two groups of plants. In this study, therefore, an attempt was made to compare the evolutionary rate, gene duplication and selective pattern of the key genes involved in this pathway between the two groups, using five grasses and five dicots as materials. The results showed (i) distinct differences in patterns of gene duplication and loss between grasses and dicots; duplication in grasses mainly occurred prior to the divergence of grasses, whereas duplication mostly occurred in individual species within the dicots; there is less gene loss in grasses than in dicots; (ii) a considerably higher evolutionary rate in grasses than in dicots in most gene families analyzed; (iii) evidence of a different selective pattern between grasses and dicots; positive selection may have occurred asymmetrically in grasses in some gene families, e.g. AGPase small subunit. Therefore, we deduced that gene duplication contributes to, and a higher evolutionary rate is associated with, the higher starch content in grasses. In addition, two novel aspects of the evolution of the starch biosynthetic pathway were observed.

Design and management of sustainable built environments

The United Nation Intergovernmental Panel on Climate Change (IPCC) makes it clear that climate change is due to human activities and it recognises buildings as a distinct sector among the seven analysed in its 2007 Fourth Assessment Report. Global concerns have escalated regarding carbon emissions and sustainability in the built environment. The built environment is a human-made setting to accommodate human activities, including building and transport, which covers an interdisciplinary field addressing design, construction, operation and management. Specifically, Sustainable Buildings are expected to achieve high performance throughout the life-cycle of siting, design, construction, operation, maintenance and demolition, in the following areas: • energy and resource efficiency; • cost effectiveness; • minimisation of emissions that negatively impact global warming, indoor air quality and acid rain; • minimisation of waste discharges; and • maximisation of fulfilling the requirements of occupants’ health and wellbeing. Professionals in the built environment sector, for example, urban planners, architects, building scientists, engineers, facilities managers, performance assessors and policy makers, will play a significant role in delivering a sustainable built environment. Delivering a sustainable built environment needs an integrated approach and so it is essential for built environment professionals to have interdisciplinary knowledge in building design and management . Building and urban designers need to have a good understanding of the planning, design and management of the buildings in terms of low carbon and energy efficiency. There are a limited number of traditional engineers who know how to design environmental systems (services engineer) in great detail. Yet there is a very large market for technologists with multi-disciplinary skills who are able to identify the need for, envision and manage the deployment of a wide range of sustainable technologies, both passive (architectural) and active (engineering system),, and select the appropriate approach. Employers seek applicants with skills in analysis, decision-making/assessment, computer simulation and project implementation. An integrated approach is expected in practice, which encourages built environment professionals to think ‘out of the box’ and learn to analyse real problems using the most relevant approach, irrespective of discipline. The Design and Management of Sustainable Built Environment book aims to produce readers able to apply fundamental scientific research to solve real-world problems in the general area of sustainability in the built environment. The book contains twenty chapters covering climate change and sustainability, urban design and assessment (planning, travel systems, urban environment), urban management (drainage and waste), buildings (indoor environment, architectural design and renewable energy), simulation techniques (energy and airflow), management (end-user behaviour, facilities and information), assessment (materials and tools), procurement, and cases studies ( BRE Science Park). Chapters one and two present general global issues of climate change and sustainability in the built environment. Chapter one illustrates that applying the concepts of sustainability to the urban environment (buildings, infrastructure, transport) raises some key issues for tackling climate change, resource depletion and energy supply. Buildings, and the way we operate them, play a vital role in tackling global greenhouse gas emissions. Holistic thinking and an integrated approach in delivering a sustainable built environment is highlighted. Chapter two demonstrates the important role that buildings (their services and appliances) and building energy policies play in this area. Substantial investment is required to implement such policies, much of which will earn a good return. Chapters three and four discuss urban planning and transport. Chapter three stresses the importance of using modelling techniques at the early stage for strategic master-planning of a new development and a retrofit programme. A general framework for sustainable urban-scale master planning is introduced. This chapter also addressed the needs for the development of a more holistic and pragmatic view of how the built environment performs, , in order to produce tools to help design for a higher level of sustainability and, in particular, how people plan, design and use it. Chapter four discusses microcirculation, which is an emerging and challenging area which relates to changing travel behaviour in the quest for urban sustainability. The chapter outlines the main drivers for travel behaviour and choices, the workings of the transport system and its interaction with urban land use. It also covers the new approach to managing urban traffic to maximise economic, social and environmental benefits. Chapters five and six present topics related to urban microclimates including thermal and acoustic issues. Chapter five discusses urban microclimates and urban heat island, as well as the interrelationship of urban design (urban forms and textures) with energy consumption and urban thermal comfort. It introduces models that can be used to analyse microclimates for a careful and considered approach for planning sustainable cities. Chapter six discusses urban acoustics, focusing on urban noise evaluation and mitigation. Various prediction and simulation methods for sound propagation in micro-scale urban areas, as well as techniques for large scale urban noise-mapping, are presented. Chapters seven and eight discuss urban drainage and waste management. The growing demand for housing and commercial developments in the 21st century, as well as the environmental pressure caused by climate change, has increased the focus on sustainable urban drainage systems (SUDS). Chapter seven discusses the SUDS concept which is an integrated approach to surface water management. It takes into consideration quality, quantity and amenity aspects to provide a more pleasant habitat for people as well as increasing the biodiversity value of the local environment. Chapter eight discusses the main issues in urban waste management. It points out that population increases, land use pressures, technical and socio-economic influences have become inextricably interwoven and how ensuring a safe means of dealing with humanity’s waste becomes more challenging. Sustainable building design needs to consider healthy indoor environments, minimising energy for heating, cooling and lighting, and maximising the utilisation of renewable energy. Chapter nine considers how people respond to the physical environment and how that is used in the design of indoor environments. It considers environmental components such as thermal, acoustic, visual, air quality and vibration and their interaction and integration. Chapter ten introduces the concept of passive building design and its relevant strategies, including passive solar heating, shading, natural ventilation, daylighting and thermal mass, in order to minimise heating and cooling load as well as energy consumption for artificial lighting. Chapter eleven discusses the growing importance of integrating Renewable Energy Technologies (RETs) into buildings, the range of technologies currently available and what to consider during technology selection processes in order to minimise carbon emissions from burning fossil fuels. The chapter draws to a close by highlighting the issues concerning system design and the need for careful integration and management of RETs once installed; and for home owners and operators to understand the characteristics of the technology in their building. Computer simulation tools play a significant role in sustainable building design because, as the modern built environment design (building and systems) becomes more complex, it requires tools to assist in the design process. Chapter twelve gives an overview of the primary benefits and users of simulation programs, the role of simulation in the construction process and examines the validity and interpretation of simulation results. Chapter thirteen particularly focuses on the Computational Fluid Dynamics (CFD) simulation method used for optimisation and performance assessment of technologies and solutions for sustainable building design and its application through a series of cases studies. People and building performance are intimately linked. A better understanding of occupants’ interaction with the indoor environment is essential to building energy and facilities management. Chapter fourteen focuses on the issue of occupant behaviour; principally, its impact, and the influence of building performance on them. Chapter fifteen explores the discipline of facilities management and the contribution that this emerging profession makes to securing sustainable building performance. The chapter highlights a much greater diversity of opportunities in sustainable building design that extends well into the operational life. Chapter sixteen reviews the concepts of modelling information flows and the use of Building Information Modelling (BIM), describing these techniques and how these aspects of information management can help drive sustainability. An explanation is offered concerning why information management is the key to ‘life-cycle’ thinking in sustainable building and construction. Measurement of building performance and sustainability is a key issue in delivering a sustainable built environment. Chapter seventeen identifies the means by which construction materials can be evaluated with respect to their sustainability. It identifies the key issues that impact the sustainability of construction materials and the methodologies commonly used to assess them. Chapter eighteen focuses on the topics of green building assessment, green building materials, sustainable construction and operation. Commonly-used assessment tools such as BRE Environmental Assessment Method (BREEAM), Leadership in Energy and Environmental Design ( LEED) and others are introduced. Chapter nineteen discusses sustainable procurement which is one of the areas to have naturally emerged from the overall sustainable development agenda. It aims to ensure that current use of resources does not compromise the ability of future generations to meet their own needs. Chapter twenty is a best-practice exemplar - the BRE Innovation Park which features a number of demonstration buildings that have been built to the UK Government’s Code for Sustainable Homes. It showcases the very latest innovative methods of construction, and cutting edge technology for sustainable buildings. In summary, Design and Management of Sustainable Built Environment book is the result of co-operation and dedication of individual chapter authors. We hope readers benefit from gaining a broad interdisciplinary knowledge of design and management in the built environment in the context of sustainability. We believe that the knowledge and insights of our academics and professional colleagues from different institutions and disciplines illuminate a way of delivering sustainable built environment through holistic integrated design and management approaches. Last, but not least, I would like to take this opportunity to thank all the chapter authors for their contribution. I would like to thank David Lim for his assistance in the editorial work and proofreading.

Fusion of infrared polarization and intensity images using support value transform and fuzzy combination rules

Infrared polarization and intensity imagery provide complementary and discriminative information in image understanding and interpretation. In this paper, a novel fusion method is proposed by effectively merging the information with various combination rules. It makes use of both low-frequency and highfrequency images components from support value transform (SVT), and applies fuzzy logic in the combination process. Images (both infrared polarization and intensity images) to be fused are firstly decomposed into low-frequency component images and support value image sequences by the SVT. Then the low-frequency component images are combined using a fuzzy combination rule blending three sub-combination methods of (1) region feature maximum, (2) region feature weighting average, and (3) pixel value maximum; and the support value image sequences are merged using a fuzzy combination rule fusing two sub-combination methods of (1) pixel energy maximum and (2) region feature weighting. With the variables of two newly defined features, i.e. the low-frequency difference feature for low-frequency component images and the support-value difference feature for support value image sequences, trapezoidal membership functions are proposed and developed in tuning the fuzzy fusion process. Finally the fused image is obtained by inverse SVT operations. Experimental results of visual inspection and quantitative evaluation both indicate the superiority of the proposed method to its counterparts in image fusion of infrared polarization and intensity images.

Evaluation of Earth system models using modern and palaeo-observations: the state-of-the-art

Earth system models are increasing in complexity and incorporating more processes than their predecessors, making them important tools for studying the global carbon cycle. However, their coupled behaviour has only recently been examined in any detail, and has yielded a very wide range of outcomes, with coupled climate-carbon cycle models that represent land-use change simulating total land carbon stores by 2100 that vary by as much as 600 Pg C given the same emissions scenario. This large uncertainty is associated with differences in how key processes are simulated in different models, and illustrates the necessity of determining which models are most realistic using rigorous model evaluation methodologies. Here we assess the state-of-the-art with respect to evaluation of Earth system models, with a particular emphasis on the simulation of the carbon cycle and associated biospheric processes. We examine some of the new advances and remaining uncertainties relating to (i) modern and palaeo data and (ii) metrics for evaluation, and discuss a range of strategies, such as the inclusion of pre-calibration, combined process- and system-level evaluation, and the use of emergent constraints, that can contribute towards the development of more robust evaluation schemes. An increasingly data-rich environment offers more opportunities for model evaluation, but it is also a challenge, as more knowledge about data uncertainties is required in order to determine robust evaluation methodologies that move the field of ESM evaluation from "beauty contest" toward the development of useful constraints on model behaviour.

Interpretation bias in preschool children at risk for anxiety: a prospective study

A story-stem paradigm was used to assess interpretation bias in preschool children. Data were available for 131 children. Interpretation bias, behavioural inhibition (BI) and anxiety were assessed when children were aged between 3 years 2 months and 4 years 5 months. Anxiety was subsequently assessed 12-months, 2-years and 5-years later. A significant difference in interpretation bias was found between participants who met criteria for an anxiety diagnosis at baseline, with clinically anxious participants more likely to complete the ambiguous story-stems in a threat-related way. Threat interpretations significantly predicted anxiety symptoms at 12-month follow-up, after controlling for baseline symptoms, but did not predict anxiety symptoms or diagnoses at either 2-year or 5- year follow-up. There was little evidence for a relationship between BI and interpretation bias. Overall, the pattern of results was not consistent with the hypothesis that interpretation bias plays a role in the development of anxiety. Instead, some evidence for a role in the maintenance of anxiety over relatively short periods of time was found. The use of a story-stem methodology to assess interpretation bias in young children is discussed along with the theoretical and clinical implications of the findings.

Evaluation of biospheric components in Earth system models using modern and palaeo-observations: the state-of-the-art

Earth system models (ESMs) are increasing in complexity by incorporating more processes than their predecessors, making them potentially important tools for studying the evolution of climate and associated biogeochemical cycles. However, their coupled behaviour has only recently been examined in any detail, and has yielded a very wide range of outcomes. For example, coupled climate–carbon cycle models that represent land-use change simulate total land carbon stores at 2100 that vary by as much as 600 Pg C, given the same emissions scenario. This large uncertainty is associated with differences in how key processes are simulated in different models, and illustrates the necessity of determining which models are most realistic using rigorous methods of model evaluation. Here we assess the state-of-the-art in evaluation of ESMs, with a particular emphasis on the simulation of the carbon cycle and associated biospheric processes. We examine some of the new advances and remaining uncertainties relating to (i) modern and palaeodata and (ii) metrics for evaluation. We note that the practice of averaging results from many models is unreliable and no substitute for proper evaluation of individual models. We discuss a range of strategies, such as the inclusion of pre-calibration, combined process- and system-level evaluation, and the use of emergent constraints, that can contribute to the development of more robust evaluation schemes. An increasingly data-rich environment offers more opportunities for model evaluation, but also presents a challenge. Improved knowledge of data uncertainties is still necessary to move the field of ESM evaluation away from a "beauty contest" towards the development of useful constraints on model outcomes.
