Cross-cultural adaptation, reliability, internal consistency and validation of the Spinal Function Sort (SFS) for French- and German-speaking patients with back complaints.

Introduction Functional subjective evaluation through questionnaire is fundamental, but not often realized in patients with back complaints, lacking validated tools. The Spinal Function Sort (SFS) was only validated in English. We aimed to translate, adapt and validate the French (SFS-F) and German (SFS-G) versions of the SFS. Methods Three hundred and forty-four patients, experiencing various back complaints, were recruited in a French (n = 87) and a German-speaking (n = 257) center. Construct validity was estimated via correlations with SF-36 physical and mental scales, pain intensity and hospital anxiety and depression scales (HADS). Scale homogeneities were assessed by Cronbach's α. Test-retest reliability was assessed on 65 additional patients using intraclass correlation (IC). Results For the French and German translations, respectively, α were 0.98 and 0.98; IC 0.98 (95% CI: [0.97; 1.00]) and 0.94 (0.90; 0.98). Correlations with physical functioning were 0.63 (0.48; 0.74) and 0.67 (0.59; 0.73); with physical summary 0.60 (0.44; 0.72) and 0.52 (0.43; 0.61); with pain -0.33 (-0.51; -0.13) and -0.51 (-0.60; -0.42); with mental health -0.08 (-0.29; 0.14) and 0.25 (0.13; 0.36); with mental summary 0.01 (-0.21; 0.23) and 0.28 (0.16; 0.39); with depression -0.26 (-0.45; -0.05) and -0.42 (-0.52; -0.32); with anxiety -0.17 (-0.37; -0.04) and -0.45 (-0.54; -0.35). Conclusions Reliability was excellent for both languages. Convergent validity was good with SF-36 physical scales, moderate with VAS pain. Divergent validity was low with SF-36 mental scales in both translated versions and with HADS for the SFS-F (moderate in SFS-G). Both versions seem to be valid and reliable for evaluating perceived functional capacity in patients with back complaints.

Cross-Cultural Adaptation and Validation of the Spinal Function Sort (SFS) for French- and German-Speaking Patients with Back Complaints

Aim: Functional subjective evaluation through questionnaire is fundamental, but not often realized in patients with back complaints, notably because of lack of validated tools, in accordance with recognized psychometric criteria. The Spinal Function Sort (SFS), developed according to actual standards, was only validated in English. The aim of this study is to translate, adapt and validate the French and German version of the SFS.Method and material: The translation and cross-cultural adaptation were performed following the methodology proposed by the American Association of Orthopedist Surgeon. A total of 344 patients, presenting varied back complaints (especially degenerative and traumatic), took part in this study in a tertiary French- (n=87; mean age 44y; 17 women) and German-speaking (n=257; mean age 41y; 53 women) center. Test-retest reliability was quantified using the intraclass correlation coefficient (ICC) and construct validity was assessed by estimating the Pearson's correlation with the SF-36 physical and mental scales, the Visual Analogue Scale for Pain Intensity (VAS), and subscales of the Hospital Anxiety and Depression Scale (HADS).Results: Respectively for the French and German version, ICC were 0.98 and 0.94. Correlations 0.63 and 0.67 with the SF-36 Physical Functioning subscale; 0.60 and 0.52 with the SF-36 Physical Summary Scale ; -0.33 and -0.51 with the VAS ; -0.08 and 0.25 with the SF-36 Mental Health scale; 0.01 and 0.28 with the SF-36 Mental Summary Scale; -0.26 and -0.42 with the HADS depression; -0.17 and -0.45 with the HADS anxiety.Discussion: For both the French and German version of the SFS, the reliability was excellent. Convergent construct validity with SF-36 physical scales is good, moderated with the VAS. We find out a low correlation with SF-36 mental scales (divergent construct validity). We find out a low correlation with HADS subscales in the French version, and a moderate one in the German version. Selection bias, chronicity of the complaints, as well as cultural differences could explain these results. In conclusion, both the French and German version of the SFS are valid and reliable for evaluation of perceived functional capacity for patients with back complaints.

Rhinopharyngeal autologous fat injection for treatment of velopharyngeal insufficiency in patients with cleft palate.

Patients with cleft palate are prone to velopharyngeal insufficiency. In minor cases or when hypernasal speech does not resolve after velopharyngoplasty, an augmentation pharyngoplasty with autologous fat can be proposed. The aim of the present study is to evaluate the short-term (within 2 months) and long-term efficiency (during the 24 months following the procedure) of our procedure in the setting of velopharyngeal insufficiency related to a cleft palate. Twenty-two patients with cleft palate related velopharyngeal insufficiency were included in this retrospective study. All patients were operated following the same technique, in the same institution. The pre- and postoperative evaluations included a nasometry, a subjective evaluation using the Borel-Maisonny score, and a nasofibroscopy to assess the degree of velopharyngeal closure. Scores of Borel-Maisonny and nasometry were compared before, shortly after the procedure (within 2 months) and long term after the procedure (within 24 months). Forty-one procedures in 22 patients with a cleft palate performed in our institution between October 2004 and January 2012 were included in the study. Nine patients had a previous velopharyngoplasty with persistent rhinolalia despite intensive speech therapy. In 14 patients the procedure was repeated because of recurrent hypernasal speech after the first injection. The average number of procedures per patient was 1.8. Postoperative nasometry and Borel-Maisonny scores were statistically significantly improved and remained stable until the end of the follow-up (median 42 months postoperative) in most patients. Complications were rare and minor. Autologous fat injection is a simple procedure for treatment of minor velopharyngeal insufficiencies in patients with cleft palate, with good long-term results and few complications.

Job Satisfaction of Spanish University Graduates

This paper investigates the determinants of job satisfaction of university graduates in Spain. We base our analysis on Locke"s discrepancy theory [Locke (1969)] and decompose subjective evaluation of job characteristics into surplus and deficit levels. We also study the importance of overeducation and over-skilling on job satisfaction. We use REFLEX data, a survey of university graduates. We conclude that job satisfaction is mostly determined by the subjective evaluation of intrinsic job characteristics, with an asymmetric impact of surpluses and deficits. Over-skilling is much more important than over-education in explaining the job satisfaction of university graduates, although the latter is also significant.

Age and gender variations of sleep in subjects without sleep disorders.

OBJECTIVE: Although sleep is a biomarker for general health and pathological conditions, its changes across age and gender are poorly understood. METHODS: Subjective evaluation of sleep was assessed by questionnaires in 5,064 subjects, and 2,966 were considered without sleep disorders. Objective evaluation was performed by polysomnography in 2,160 subjects, and 1,147 were considered without sleep disorders. Only subjects without sleep disorders were included (aged 40-80 years). RESULTS: Aging was strongly associated with morning preference. Older subjects, especially women, complained less about sleepiness, and pathological sleepiness was significantly lower than in younger subjects. Self-reported sleep quality and daytime functioning improved with aging. Sleep latency increased with age in women, while sleep efficiency decreased with age in both genders. Deep slow-wave sleep decreased with age, but men were more affected. Spectral power densities within slow waves (< 5 Hz) and fast spindles (14-14.75 Hz) decreased, while theta-alpha (5-1 Hz) and beta (16.75-25 Hz) power in non-rapid eye movement sleep increased with aging. In REM sleep, aging was associated with a progressive decrease in delta (1.25-4.5 Hz) and increase in higher frequencies. CONCLUSIONS: Our findings indicate that sleep complaints should not be viewed as part of normal aging but should prompt the identification of underlying causes.

Paperin aistinvarainen arviointi

Paperin tärkeiden teknisten ominaisuuksien lisäksi myös paperin aistinvaraiset ominaisuudet ovat nousseet merkittäviksi parametreiksi paperia luonnehdittaessa. Aistinvaraisilla ominaisuuksilla tarkoitetaan ominaisuuksia, jotka ihminen aistii käsitellessään tuotetta. Tällaisia ominaisuuksia ovat esimerkiksi paperin karheus, liukkaus, jäykkyys sekä ääni paperia selattaessa. Paperin aistinvaraiset ominaisuudet luovat lukijalle mielikuvan lukemastaan lehdestä lehden sisällön lisäksi. Tämän työn tavoitteena oli kehittää olemassa olevan aistinvaraisten ominaisuuksien arviointiraadin toimintaa. Arviointimenetelmän tilalle pyrittiin löytämään toinen menetelmä sekä kehittämään uusi tulosten raportointimalli. Työssä käytettiin kahta subjektiivista arviointimenetelmää, parivertailua ja ranking-menetelmää. Tuloksia verrattiin aiemmin käytössä olleen referenssimenetelmän tuloksiin. Näytteistä arvioitiin karheus, liukkaus, tahmeus, jäykkyys, selailtavuus, äänen voimakkuus ja äänen laatu. Näiden lisäksi näytteiden miellyttävyyttä arvioitiin parivertailua käyttäen. Arvioitsijoiden yksimielisyyttä selvitettiin parivertailun yhteydessä. Näytteet olivat painamattomia, mutta painokoneen läpi menneitä lehtiformaattiin taitettuja. Visuaalisissa arvioinneissa käytettiin painettuja näytteitä samasta paperivalikoimasta. Arviointimenetelmien tuloksia vertailtaessa, voidaan menetelmien välillä havaita muutamia eroja. Sekä parivertailussa että ranking-menetelmässä näytteet jakaantuivat lähes kokonaan annetulle arviointiskaalalle, kun referenssimenetelmällä ne kasautuivat hyvin pienelle alueelle. Ranking-menetelmässä näytteet jakautuivat vielä laajemmalle kuin parivertailussa. Parivertailu erotteli näytteet paremmin toisistaan kuin referenssimenetelmä. Ranking-menetelmän ja parivertailun välillä vastaavaa eroa erotuskyvyssä ei havaittu. Tulosten perusteella voidaan sanoa, että parivertailu

Computational visual quality of digitally printed images

The problem of understanding how humans perceive the quality of a reproduced image is of interest to researchers of many fields related to vision science and engineering: optics and material physics, image processing (compression and transfer), printing and media technology, and psychology. A measure for visual quality cannot be defined without ambiguity because it is ultimately the subjective opinion of an “end-user” observing the product. The purpose of this thesis is to devise computational methods to estimate the overall visual quality of prints, i.e. a numerical value that combines all the relevant attributes of the perceived image quality. The problem is limited to consider the perceived quality of printed photographs from the viewpoint of a consumer, and moreover, the study focuses only on digital printing methods, such as inkjet and electrophotography. The main contributions of this thesis are two novel methods to estimate the overall visual quality of prints. In the first method, the quality is computed as a visible difference between the reproduced image and the original digital (reference) image, which is assumed to have an ideal quality. The second method utilises instrumental print quality measures, such as colour densities, measured from printed technical test fields, and connects the instrumental measures to the overall quality via subjective attributes, i.e. attributes that directly contribute to the perceived quality, using a Bayesian network. Both approaches were evaluated and verified with real data, and shown to predict well the subjective evaluation results.

Facteurs influençant la consolidation et l’apprentissage d’une habileté motrice chez l’humain

La pratique physique a longtemps été perçue comme le déterminant premier de l’apprentissage du mouvement. Souvent exprimée par l’expression « Vingt fois sur le métier remettez votre ouvrage», cette idée se base sur l’observation qu’une grande quantité de pratique est nécessaire pour maîtriser un geste technique complexe. Bien que l’importance de la pratique physique pour l’apprentissage du mouvement demeure indéniable, il a récemment été démontré que les changements neurobiologiques qui constituent les bases de la mémoire prennent place après la pratique. Ces changements, regroupés sous le terme « consolidation », sont essentiels à la mise en mémoire des habiletés motrices. L’objectif de cette thèse est de définir les processus de consolidation en identifiant certains facteurs qui influencent la consolidation d’une habileté motrice. À l’aide d’une tâche d’adaptation visuomotrice comportant deux niveaux de difficulté, nous avons démontré qu’une bonne performance doit être atteinte au cours de la séance de pratique pour enclencher certains processus de consolidation. De plus, nos résultats indiquent que l’évaluation subjective que l’apprenant fait de sa propre performance peut moduler la consolidation. Finalement, nous avons démontré que l’apprentissage par observation peut enclencher certains processus de consolidation, indiquant que la consolidation n’est pas exclusive à la pratique physique. Dans l’ensemble, les résultats des études expérimentales présentées dans cette thèse montrent que la consolidation regroupe plusieurs processus distincts jouant chacun un rôle important pour l’apprentissage du mouvement. Les éducateurs physiques, les entraineurs sportifs et les spécialistes de la réadaptation physique devraient donc planifier des entrainements favorisant non seulement l’acquisition de gestes moteurs mais également leur consolidation.

Étude des mécanismes psychophysiologiques de la modulation volontaire de la douleur par le biofeedback et la respiration.

Bien que la douleur soit une expérience subjective universelle, la façon de la percevoir et de l’interpréter est modulée par une multitude de facteurs. Plusieurs interventions cognitives se sont montrées efficaces pour réduire la douleur dans des conditions cliniques et expérimentales. Cette thèse s’intéressera particulièrement aux mécanismes psychophysiologiques impliqués dans les stratégies de modulation volontaire de la douleur. Ces stratégies sont intéressantes puisqu’elles encouragent une prise en charge par l’individu, lui permettant de jouer un rôle actif dans la régulation de sa douleur. La première étude s’intéresse à l’efficacité du biofeedback comme moyen de modulation volontaire de la douleur. Il s’agissait de déterminer si le fait de présenter une rétroaction de l’amplitude du réflex RIII (évoqué par une stimulation électrique du nerf sural) au cours d’un entraînement de plusieurs essais permettrait au participant d’adopter des stratégies de modulation de la douleur et d’activer volontairement des mécanismes de contrôle descendant de la douleur. De façon à évaluer spécifiquement les changements induits par le biofeedback, la modulation du réflexe RIII et de la douleur était comparée dans trois groupes (biofeedback valide, faux biofeedback et groupe contrôle sans rétroaction). Dans les trois groupes, il était suggéré aux participants d’utiliser des stratégies cognitives de modulation de la douleur (attention, modulation de la respiration, réévaluation cognitive et imagerie mentale) afin d’augmenter ou de diminuer leur réflexe RIII comparativement à leur niveau de base. Les résultats de notre étude indiquent que les participants des 3 groupes ont réussi à moduler leur réflexe RIII (p<0,001) ainsi que leurs évaluations de douleur (p<0,001) (intensité et désagrément). Les résultats de notre étude montrent que l’entraînement au biofeedback n’était pas nécessaire pour obtenir une modulation du réflexe RIII et de la douleur, ce qui suggère que l’utilisation de stratégies cognitives pourrait être suffisante pour déclencher des mécanismes de contrôle de la douleur. La deuxième étude découle de la première et s’intéressait à l’influence de la fréquence et de la phase respiratoire sur la nociception spinale, l’activité cérébrale et la perception de douleur. Le contrôle volontaire de la respiration est un moyen commun de régulation des émotions et est fréquemment utilisé en combinaison avec d’autres techniques (ex. : relaxation, méditation) dans le but de réguler la douleur. Les participants étaient invités à synchroniser leur respiration à des indices sonores indiquant le moment de l’inspiration et de l’expiration. Trois patrons de respiration étaient proposés (respiration à 0,1Hz avec une inspiration de 4 secondes, respiration à 0,1Hz avec une inspiration de 2 secondes et respiration à 0,2Hz avec une inspiration de 2 secondes. La moitié des stimulations étaient données durant l’inspiration et l’autre moitié durant l’expiration. Afin d’évaluer l’effet de ces manipulations, l’amplitude du RIII, l’évaluation subjective d’intensité de la douleur et de l’anxiété suscitée par le choc en plus des potentiels évoqués étaient mesurés. Les résultats de cette étude démontrent que les évaluations d’intensité de la douleur n’étaient pas affectées par le patron respiratoire (p=0,3), mais étaient statistiquement plus basses durant l’inspiration comparativement à l’expiration (p=0,02). Un effet de phase (p=0,03) était également observé sur les potentiels évoqués durant la condition de respiration à 0,1hHz avec une inspiration de 2 secondes comparativement au patron de respiration de 0,2Hz. Paradoxalement, l’amplitude du réflexe RIII était augmenté durant l’inspiration (p=0,02) comparativement à l’expiration. Ces résultats montrent que la manipulation de la fréquence et de la phase respiratoires (par une synchronisation imposée) a un effet marginal sur les évaluations de douleur et sur l’activité cérébrale et spinale évoquée par une stimulation électrique (douleur aigüe). Cela suggère que d’autres mécanismes contribuent aux effets analgésiques observés dans la relaxation et la méditation. Plus largement, nos résultats font état de la nécessité d’études plus approfondies avec une méthodologie plus rigoureuse afin de contrôler les effets non spécifiques aux traitements évalués. Une meilleure connaissance des mécanismes sous-tendant chaque stratégie permettrait de mieux cibler les clientèles susceptibles d’y répondre et de mieux considérer le ratio coût bénéfice de chaque traitement.

Determinación del perfil de exposición potencial a contaminantes químicos mediante el uso de metodologías de evaluación simplificada en trabajadores de autopartes en el barrio La Paz, Bogotá 2015

Las actividades de mantenimiento automotriz en el sector de autopartes conlleva el uso de agentes químicos bajo diversas circunstancias de exposición, tanto en las condiciones de manipulación de productos químicos como a las características propias de cada actividad de mantenimiento asociado a las tareas específicas del trabajo. Tradicionalmente la evaluación de contaminantes químicos desde la visión de la Higiene Ocupacional incluye la evaluación cuantitativa de la exposición mediante técnicas instrumentales concretas y estandarizadas, determinando el nivel de concentración en aire a la cual un trabajador se ve expuesto y que, en comparación con valores límites permisibles (VLPs), inducen el establecimiento de medidas de control y vigilancia, según el nivel de riesgo caracterizado. Sin embargo es evidente la limitación de la implementación de esta sistemática en particular en micros y pequeñas empresas que carecen de los recursos suficientes para abordar la problemática de forma objetiva. En este contexto diversas metodologías de evaluación cualitativa o subjetiva se han desarrollado por distintas organizaciones en el mundo con el fin de disminuir la brecha entre el establecimiento de medidas de control y la valoración del riesgo, ofreciendo alternativas confiables para la toma de decisiones preventivas sin la necesidad de acudir a mediciones cuantitativas. Mediante la presente investigación se pretende validar la efectividad en el uso de una herramienta de evaluación simplificada del riesgo químico propuesta por el INRS (Institut National de Recherche et de Sécurité Francés) mediante la determinación del perfil de exposición potencial a contaminantes químicos de la población laboral de 36 almacenes de autopartes ubicados en el barrio la Paz de la ciudad de Bogotá, Colombia, divididos según énfasis de actividades en Partes Externas, Partes Eléctricas e Inyección, Partes Mecánicas, Partes Múltiples, a través de un estudio de corte transversal. El estudio permitió Jerarquizar el riesgo potencial, valorar el riesgo vía inhalatoria y dérmica para finalmente construir el perfil de exposición potencial a contaminantes químicos de trabajadores. La información de las variables de análisis fue consolidada en una herramienta informática diseñada para tal fin, la cual facilito la administración de los datos y su respectivo análisis. Con base en los hallazgos fue posible establecer los productos químicos que de acuerdo a las condiciones de trabajo y circunstancias de exposición sugieren medidas específicas para la disminución del riesgo potencial de acuerdo a la calificación global de los agentes, permitiendo deducir la viabilidad de la aplicación de herramientas de valoración cualitativa para la evaluación del riesgo químico como estrategia de prevención primaria.

À procura da identidade de Heinz : um modelo de compreensão da motivação moral

RESUMO: As teorias psicológicas da moralidade dividem-se na conceptualização da motivação moral, o tema desta dissertação. Os modelos construtivistas, apoiados na epistemologia genética, privilegiam a cognição como factor determinante mas, as teorias que enfatizam o funcionamento individual admitem que as emoções e a identidade interferem na tendência de cada pessoa agir moralmente. Particularmente apoiados na segunda perspectiva, testámos um modelo preditor da motivação moral com três variáveis, identidade, identidade moral e integridade, todas avaliadas por medidas psicométricas, em duas amostras. A primeira era composta por 320 estudantes do 12º ano de uma escola do concelho de Lisboa, com idades compreendidas entre 18 e 20 anos (M=18,22; Dp=0,49), 108 masculinos e 194 femininos e a segunda era composta por 174 sujeitos, estudantes finalistas de cursos profissionais de uma escola do concelho de Lisboa frequentada por alunos provenientes de ambientes sociais caracterizados pelo stresse sócio-económico e familiar, e até, em bastantes casos, que já tinham participado em actos ilegais relacionados com furto, vandalismo, tráfico de drogas, e agressões, com idades compreendidas entre 18 e 22 anos (M=18,98; Dp=1,075), 104 masculinos e 70 femininos. A primeira amostra foi considerada normativa e a segunda de risco psicossocial. Para avaliar a motivação moral foi construída uma medida que incluiu dois aspectos: a consciência moral, relativa à avaliação objectiva e subjectiva que os indivíduos fazem das situações morais que através de processos de análise de conteúdo foi distinguida em três categorias exclusivas: não transgressão, transgressão relativizada e transgressão; e a autoatribuição de emoções que indica a probabilidade objectiva dos indivíduos cometerem acções morais. Foi verificada a existência de diferenças individuais em ambas as medidas da motivação moral e, também, a existência de diferenças na atribuição de emoções em função da consciência moral: os sujeitos da categoria transgressão apresentaram atribuições mais negativas do que os sujeitos de transgressão relativizada e estes, por sua vez, apresentaram atribuições mais negativas que os sujeitos da categoria não transgressão. Estes resultados confirmam o papel da identidade na motivação moral. A análise da predição confirmou que a integridade, a identidade e a identidade moral, em ordem decrescente de capacidade explicativa, constituem factores preditores tanto da consciência moral como da auto-atribuição de emoções. ABSTRACT: Moral motivation, the subject of this thesis, is differently viewed by several psychological perspectives. Constructivist models supported by genetic epistemology define cognition as the determinant factor while theories that emphasize individual functioning admit that emotions and identity have a central role in the way that persons could morally act. Particularly supported in this second approach we tested a predictive model of moral motivation with three variables, identity, moral identity and integrity, all evaluated by psychometric scales, in two samples. The first sample had 320 graduate high school students with age between 18 and 20 (M=18,22; SD=0,49), 108 male and 194 female and the second sample had 174 graduate students of vocational courses in high school of a risk social and familiar environment, many of them had already done illegal acts such as stealing, vandalism, drug traffic and aggressions; they had ages between 18 and 22 (M=18,98; SD=1,08), 104 male and 70 female. The first sample was considered normative and the second one was classified as psychosocial risk. To evaluate moral motivation we developed a measure that assesses two aspects: moral conscience, who includes both objective and subjective evaluation of moral situations that was distinguished in three exclusive categories by procedures of content analysis: non-transgression, justifiable transgression and transgression; and self-attribution of emotion that indicates the likelihood of committing moral actions. We observed individual differences in both measurements of moral motivation and also verified differences in emotional attribution on the basis of moral conscience: the individuals of transgression category presented more negative attributions than those of justifiable transgression and in turn the latter presented more negative attributions than individuals of non-transgression category. These results confirm the role of identity in moral motivation. The predictor analysis confirmed integrity, identity and moral identity, in descending order of explanatory power, as predictive variables of moral consciousness and self-attribution of emotions.

Characteristics of high-resolution versions of the Met Office unified model for forecasting convection over the United Kingdom

With many operational centers moving toward order 1-km-gridlength models for routine weather forecasting, this paper presents a systematic investigation of the properties of high-resolution versions of the Met Office Unified Model for short-range forecasting of convective rainfall events. The authors describe a suite of configurations of the Met Office Unified Model running with grid lengths of 12, 4, and 1 km and analyze results from these models for a number of convective cases from the summers of 2003, 2004, and 2005. The analysis includes subjective evaluation of the rainfall fields and comparisons of rainfall amounts, initiation, cell statistics, and a scale-selective verification technique. It is shown that the 4- and 1-km-gridlength models often give more realistic-looking precipitation fields because convection is represented explicitly rather than parameterized. However, the 4-km model representation suffers from large convective cells and delayed initiation because the grid length is too long to correctly reproduce the convection explicitly. These problems are not as evident in the 1-km model, although it does suffer from too numerous small cells in some situations. Both the 4- and 1-km models suffer from poor representation at the start of the forecast in the period when the high-resolution detail is spinning up from the lower-resolution (12 km) starting data used. A scale-selective precipitation verification technique implies that for later times in the forecasts (after the spinup period) the 1-km model performs better than the 12- and 4-km models for lower rainfall thresholds. For higher thresholds the 4-km model scores almost as well as the 1-km model, and both do better than the 12-km model.

Estudo experimental sobre a precisão e validade dos escores introversão-extroversão de uma adaptação brasileira do Maudsley Personality Inventory de H.J. Eysenck

O propósito dos trabalhos experimentais expostos na presente dissertação foi o de estudar a versão brasileira do Maudaley Personality Inventory. de Eysench. no que diz respeito à sua dimensão bipolar introversão-extroversão. A adaptação brasileira (devida à Professora Riva Bauzer) foi aplicada por duas vezes a 70 estudantes, de quatro turmas do Colégio Batista Shepard, que são nossos alunos de psicologia. Paralelamente a esta aplicação, foi aplicado por duas vezes sucessivas, aos mesmos alunos, um questionário por nós organizado. Nele era pedida a cada um uma avaliação subjetiva do grau de introversão-extroversão dos respectivos colegas de classe. Desse modo tivemos a possibilidade de avaliar: a) o coeficiente de precisão do questionário; b) o coeficiente de precisão do Maudeley Personality Inventory; c) o coeficiente de validade do Maudaley Persona lity Inventory, tomando o questionário como critério de validação. Entretanto, nao terminaram ai nossos trabalhos. Por meio do coeficiente de correlação bisserial, foi estimado o poder discriminante de cada uma das questões do Maudsley Personality Inventory, assim como seu grau de "popularidade". Esta é uma denominação por nós atribuida à porcentagem de sujeitos que assinalaram a questão no sentido de extroversão. Estes elementos abrem caminho para a realização de pesquisas ulteriores com a finalidade de aperfeiçoar a versão brasileira do Maudsley Personality Inventory.

Desenvolvimento de um modelo de gestão do conhecimento para a melhoria do processo de desenvolvimento de produtos

The knowledge management has received major attention from product designers because many of the activities within this process have to be creative and, therefore, they depend basically on the knowledge of the people who are involved in the process. Moreover, Product Development Process (PDP) is one of the activities in which knowledge management manifests in the most critical form once it had the intense application of the knowledge. As a consequence, this thesis analyzes the knowledge management aiming to improve the PDP and it also proposes a theoretical model of knowledge management. This model uses five steps (creation, maintenance, dissemination, utilization and discard) through the verification of the occurrence of four types of knowledge conversion (socialization, externalization, combination and internalization) that it will improve the knowledge management in this process. The intellectual capital in Small and Medium Enterprises (SMEs) managed efficiently and with the participation of all employees has become the mechanism of the creation and transference processes of knowledge, supporting and, consequently, improving the PDP. The expected results are an effective and efficient application of the proposed model for the creation of the knowledge base within an organization (organizational memory) aiming a better performance of the PDP. In this way, it was carried out an extensive analysis of the knowledge management (instrument of qualitative and subjective evaluation) within the Design department of a Brazilian company (SEBRAE/RN). This analysis aimed to know the state-of-the-art of the Design department regarding the use of knowledge management. This step was important in order to evaluate in the level of the evolution of the department related to the practical use of knowledge management before implementing the proposed theoretical model and its methodology. At the end of this work, based on the results of the diagnosis, a knowledge management system is suggested to facilitate the knowledge sharing within the organization, in order words, the Design department
