The cognitive dynamics of beliefs: The role of discrepancy, credibility, and involvement on microprocesses of judgment

This dissertation investigates the process of belief change by examining the time course of beliefs. The time course of belief change during judgment provides information about dynamic aspects of the cognitive system, cognitive responses during judgment, and the effect of distal variables on belief change. Several previous studies obtained individual belief trajectories using a computer mouse technique to observe the time course of belief change. Based on characteristics of belief trajectories, this study developed a new framework for their analysis. This framework allows analyses not only of overall but also of micro aspects of belief change during judgment. Hypotheses about the time course of belief changes were developed and tested with four data sets from three previous studies. Total N = 267. This study found the following: (1) Belief change during message receipt reflects the structure and properties of the message; (2) belief change during the post-message phase shows some oscillatory and some damping dynamics; (3) message discrepancy and source credibility have dynamic effects on belief change during judgment. This study generally supports dynamic models of belief change. Methodologically, this study suggests that belief trajectories can provide on-line information about cognitive responses and micro belief changes during judgment

Discutindo a educação ambiental no cotidiano escolar: desenvolvimento de projetos na escola formação inicial e continuada de professores

A presente pesquisa buscou discutir como a Educação Ambiental (EA) vem sendo trabalhada, no Ensino Fundamental e como os docentes desta escola compreendem e vem inserindo a EA no cotidiano escolar., em uma escola estadual do município de Tangará da Serra/MT, Brasil. Para tanto, realizou-se entrevistas com os professores que fazem parte de um projeto interdisciplinar de EA na escola pesquisada. Verificou-se que o projeto da escola não vem conseguindo alcançar os objetivos propostos por: desconhecimento do mesmo, pelos professores; formação deficiente dos professores, não entendimento da EA como processo de ensino-aprendizagem, falta de recursos didáticos, planejamento inadequado das atividades. A partir dessa constatação, procurou-se debater a impossibilidade de tratar do tema fora do trabalho interdisciplinar, bem como, e principalmente, a importância de um estudo mais aprofundado de EA, vinculando teoria e prática, tanto na formação docente, como em projetos escolares, a fim de fugir do tradicional vínculo “EA e ecologia, lixo e horta”.Facultad de Humanidades y Ciencias de la Educació

Biased systematic and heuristic processing of politicians' messages: effects of source favourability and political interest of attitude judgment

This study investigated two information-processing modes for political messages from favored politicians: “biased” systematic processing and heuristic processing. In an experiment, college students (N = 183) with different levels of political interest received messages about unfamiliar political issues from either a favored or a less favored candidate in the 2008 U.S. presidential election. For those with low levels of political interest, source favorability had a direct effect on attitudes, indicating heuristic processing. For those with high political interest, source favorability had an indirect effect on attitudes through message-relevant thoughts, indicating biased systematic processing. Theoretical and practical implications of the findings are discussed

Inspiration by Role Models: The Effect of Source Similarity, Perceived Goal Attainability, and Dispositional Optimism

Our experiences on social network sites (SNS) can often leave us envious of others, but others’ success can be inspirational as well. This study was an exploration of how source similarity, dispositional optimism, and goal attainability influence the outcomes of upward social comparisons with outstanding others. In an experiment in which participants were exposed to a success story on SNS (N = 200), source similarity was found to have a direct influence on inspiration, and dispositional optimism had an indirect influence on inspiration through perceived goal attainability. The findings provide both theoretical and practical implications regarding how best to utilize success stories on SNS to increase a sense of inspiration

Elucidation of flexible metal-organic frameworks: Research progresses and recent developments

Flexibility is a unique property of metal-organic frameworks (MOFs) that differentiates them from other rigid inorganic porous materials such as zeolites and porous silica. Flexible frameworks are not only scientifically interesting, but also applicable for real-world gas storage/delivery, separation, sensing, and catalysis. So far, a plethora of MOFs with flexible frameworks, termed as ???soft porous crystal???, ???flexible MOF???, ???breathing MOF???, ???sponge-like MOF??? or ???dynamic MOF???, has emerged as a new subclass of MOFs. In this review, we discuss diverse perspectives and approaches to understand and control the flexible behaviour in an archetypal MOF platform so that the basic principles can be imparted to the broad community of chemists, materials scientists, and engineers. In addition, potential applications of flexible MOFs will be briefly introduced along with advanced analytic tools and molecular modelling that aid the exploration of the flexibility of MOFs in various conditions and widen the insight to design of novel flexible MOFs

Association of Hepatic Steatosis Index with Nonalcoholic Fatty Liver Disease Diagnosed by Non-Enhanced CT in a Screening Population

The noninvasive diagnosis of hepatic steatosis is of increasing concern. This study investigated the association of hepatic steatosis determined by non-enhanced CT criteria with clinical parameters in a screening population. Asymptomatic patients who underwent abdominal CT at our healthcare center were retrospectively analyzed (n = 339). Two radiologists measured the attenuation values of the liver parenchyma and spleen using non-enhanced CT images. CT criteria for hepatic steatosis were (a) absolute liver attenuation value <48 Hounsfield units (HU), (b) liver-to-spleen attenuation ratio <0.8, and (c) attenuation difference between the liver and spleen <−10. Body mass index (BMI) and hepatic steatosis index (HSI) were calculated, and laboratory findings were recorded. The association of hepatic steatosis with clinical parameters was assessed using univariate and logistic regression analyses. The presence of hepatic steatosis was significantly associated with the levels of serum fasting glucose and triglycerides, the alanine aminotransferase to aspartate aminotransferase (ALT/AST) ratio, BMI, and HSI values using any of the CT criteria. Logistic regression analysis revealed that the serum fasting glucose level and HSI were significantly associated with hepatic steatosis using criterion (a), while the ALT/AST ratio and HSI were associated with hepatic steatosis using criteria (b) and (c). The presence of hepatic steatosis on non-enhanced CT should be considered to indicate possible clinical profile abnormalities regarding metabolic syndrome
