The impact of sodium chloride reduction and its substitution for micronized salt on consumer acceptance of turkey ham was investigated. Five formulations - F1 (control - 2.0% NaCl), F2 (1.7% NaCl), F3 (1.4% NaCl), F4 (1.7% micronized NaCl), and F5 (1.4% micronized NaCl) - were evaluated with respect to sodium chloride content and by consumers using a nine-point hedonic scale for overall acceptability and CATA (check-all-that-apply) using 24 sensory descriptors. Trained panelists characterized the products using the flash profiling technique. Reductions in the salt content by up to 30% did not affect the overall acceptability of the samples by the consumers. However, the consumers characterized the formulations with lower salt content as "less salty and less seasoned" in comparison to the contents in the control. Products containing 1.7% NaCl were considered very similar to the control. The results obtained indicate that it is possible to reduce NaCl content by 30% without affecting consumer acceptance of the product. The use of micronized salt did not affect the sensory characteristics when compared with those of formulations containing the same level of sodium chloride indicating that micronized salt does not influence perception of salt.

Memories of historical injustices affect contemporary politics from local to global level. In East Asia, questions of commemoration and historical responsibility have turned into international and domestic controversies. The main focus has been and still is in apologies conducted by Japanese prime ministers in regards to the war, aggression and colonialism during the era of Imperial Japan. Although it is granted that state apologies are not a crucial part of reconciliation, they can be analysed as a linked but separate process within the context of memory and international relations. The purpose of this study is to examine the discourses of history in Japanese prime ministers’ commemoration speeches on Memorial Ceremony for the War Dead from 1995 to 2015 in order to analyse how the Japanese government is reflecting on its past. In particular, attention is paid on what is being commemorated and how, whether it is the war and its victims or Japan’s post-war era of peace. As an apology is a reciprocal activity, responses from Japan’s most vocal former victims, South Korea and China, were also examined. Discourse analysis was used to identify and examine the different representations of the past. In addition, the apology statements of Japanese prime ministers were analysed in the Many to Many apology framework developed by Tavuchis (1991). Primary material consisted of 21 prime ministers’ speeches from the annual Memorial Ceremony for the War Dead on August 15th and from three apology statements made in 1995, 2005 and 2015. Further international context was primarily collected from newspaper articles of The New York Times and The Times throughout the examined period. It can be concluded from the findings that in the official Japanese remembrance of the past war from 1985’s annexation of Taiwan to the atomic bombings in 1945, both discourses that reinforce apology and remorse over Japan’s past aggressions and discourses that consciously avoid doing so are used. The commemoration speeches and apology statements consistently assert that Japan has acknowledged its past and expresses regret over the acts of aggression. At the same time, the speeches and statements strengthen the narrative that Japan was a victim of circumstances as well as turn the focus on post-war peace-making or on Japan’s own victimhood.

The present research study examined the relationships in a work motivation context among perceived importance and achievement of work values, locus of control and internal work motivation. The congruence of a work value was considered to be the discrepancy between the importance of a work value and the perceived achievement of that value. The theoretical framework utilized was based on a self-perpetuating cycle of motivation which included the perceived importance and achievement of work values and internal work motivation as separate and distinct, yet interrelated factors. It was hypothesized that individuals who experienced high congruence of work values would experience higher levels of internal work motivation than individuals who had low congruence of work values. It was also hypothesized that individuals who had an internal locus of control would experience more internal work motivation individuals well, the and have higher congruence of work values than who had an external locus of control. As possibility of locus of control as a moderator between importance of work values and internal work motivation was explored. Survey data were collected from 184 managerial level employees of the XYZ company during an ongoing training session. The following instruments were employed to measure the variables: Elizur's (1984) Importance of Work Values, Hunt and Saul's (1985) Achievement of Work Values, Hatfield, Robinson and Huseman's (1975) Job Perception Scale, a modified version of Rotter's (1966) I-E Locus of Control Scale and the Internal Work Motivation Scale (Hackman & Oldham, 1980) which is a part of the Job Diagnostic Survey. The findings indicated that locus of control was not a significant factor in determining congruence between work values or internal work motivation for this sample. Furthermore, locus of control was also found not to be a moderator between the importance of work values and internal work motivation. All individuals in this study had relatively high levels of internal work motivation. However, individuals who had higher congruence of work values did have significantly higher internal work motivation than those who had low congruence of work values for a majority of the 21 values. This was particularly true for the intrinsic values which included responsibility, meaningfulness and use of abilities. In addition, the data were analysed into a hierarchy of needs to indicate possible organizational development or human resource development needs for the XYZ corporation.

Aggressive behaviours within the sport of hockey appear to be increasing in both prevalence and consequence (Biasca, Wirth, & Tegner, 2002). Accordingly, this area of inquiry is currently garnering a considerable amount of attention from society and academics alike. The problem however, is that our current understanding of these behaviours has been deemed both incomplete and unreliable. The inconsistencies inherent within this body of knowledge have been traced back to a variety of methodological shortcomings. The purpose of this investigation was to assess hostile aggression using a more ecologically valid and comprehensive research design. Ten Junior B hockey games were tapped and subsequently coded by three independent observers, using a validated operational list. Two hundred and fifty-nine behaviours were extrapolated and examined according to the score differential, period, position of the aggressor, status of the aggressor's team, and whether the aggressor was a member of the home or visiting team. It was concluded that the frequency of aggressive behaviours significantly differed according to the score differential, and status of the aggressor's team (p < .01). However, these hostile acts did not differ according the aggressor's position, period, and the home versus away status of the aggressor's team (p > .01). It was also determined that the majority of aggressive acts (69.1 1%) across these ten games went unsanctioned. This highlights the profound influence that "positive misses" have on penalty measures of aggression, while concurrently highlighting the ecological validity present with observational designs. Consequently, by assessing aggressive behaviour in a more inclusive and ecologically valid manner, a more accurate picture of the frequency and distribution of hostile aggression may be provided.

Over the years, researchers have investigated direct, conditional, and meditational pathways of adolescent aggression in relation to both temperament and parenting behaviours. However, no study to date has considered these relations with respect to a measure of aggression differentiated by form (e.g., overt, relational) and function (e.g., proactive, reactive). The present study examined the differential association of adolescent temperament and authoritative parenting on four subtypes of aggression. Participants included mothers, fathers, and one adolescent (between the ages of 10-19) from 663 families, recruited through random digit dialing. Parents reported on their child's temperament and occurrence of aggressive behaviours in addition to the perception of their own authoritative parenting. Adolescents reported on their own temperament and aggressive behaviours as well as on both their mother and father's authoritative parenting. Multiple regression analyses confirmed predictions that some aspects of temperament and authoritative parenting provide motivation towards the engagement of different aggressive behaviours. For example, higher negative affect was related to reactive types of aggression, whereas a strong desire for novel or risky behaviours related to proactive aggression. However, differences in effortful control altered the trajectory for both relationships. Higher levels of self-regulation reduced the impact of negative affect on reactive-overt aggression. Greater self-regulation also reduced the impact of surgency on proactive-overt aggression when age was a factor. Structural equation modeling was then used to assess the process through which adolescents become more or less susceptible to impulsive behaviours. Although the issue ofbi-directionality cannot be ruled out, temperament characteristics were the proximal correlate for aggression subtypes as opposed to authoritative parenting dimensions. Effortful control was found to partially mediate the relation between parental acceptancelinvolvement and reactive-relational and reactive-overt aggression, suggesting that higher levels of warmth and support as perceived by the child related to increased levels of self-regulation and emotional control, which in tum lead to less reactive-relational and less reactive-overt types of aggression in adolescents. On the other hand, negative affect partially mediated the relation between parental psychological autonomy granting and these two subtypes of aggression, supporting predictions that higher levels of autonomy granting (perceived independence) related to lower levels of frustration, which in tum lead to less reactive-relational and reactive-overt aggression in adolescents. Both findings provide less evidence for the evocative person-environment correlation and more support for temperament being an open system shaped by experience and authoritative parenting dimensions. As one of the first known studies examining the differential association of authoritative parenting and temperament on aggression subtypes, this study demonstrates the role parents can play in shaping and altering their children's temperament and the effects it can have on aggressive behaviour.

The present set of experiments was designed to investigate the development of children's sensitivity of facial expressions observed within emotional contexts. Past research investigating both adults' and children's perception of facial expressions has been limited primarily to the presentation of isolated faces. During daily social interactions, however, facial expressions are encountered within contexts conveying emotions (e.g., background scenes, body postures, gestures). Recently, research has shown that adults' perception of facial expressions is influenced by these contexts. When emotional faces are shown in incongruent contexts (e.g., when an angry face is presented in a context depicting fear) adults' accuracy decreases and their reaction times increase (e.g., Meeren et a1. 2005). To examine the influence of emotional body postures on children's perception of facial expressions, in each of the experiments in the current study adults and 8-year-old children made two-alternative forced choice decisions about facial expressions presented in congruent (e.g., a face displayed sadness on a body displaying sadness) and incongruent (e.g., a face displaying fear on a body displaying sadness) contexts. Consistent with previous studies, a congruency effect (better performance on congruent than incongruent trials) was found for both adults and 8-year-olds when the emotions displayed by the face and body were similar to each other (e.g., fear and sad, Experiment l a ) ; the influence of context was greater for 8-year-olds than adults for these similar expressions. To further investigate why the congruency effect was larger for children than adults in Experiment 1 a, Experiment 1 b was conducted to examine if increased task difficulty would increase the magnitude of adults' congruency effects. Adults were presented with subtle facial and despite successfully increasing task difficulty the magnitude of the. congruency effect did not increase suggesting that the difference between children's and adults' congruency effects in Experiment l a cannot be explained by 8-year-olds finding the task difficult. In contrast, congruency effects were not found when the expressions displayed by the face and body were dissimilar (e.g., sad and happy, see Experiment 2). The results of the current set of studies are examined with respect to the Dimensional theory and the Emotional Seed model and the developmental timeline of children's sensitivity to facial expressions. A secondary aim of the series of studies was to examine one possible mechanism underlying congruency effe cts-holistic processing. To examine the influence of holistic processing, participants completed both aligned trials and misaligned trials in which the faces were detached from the body (designed to disrupt holistic processing). Based on the principles of holistic face processing we predicted that participants would benefit from misalignment of the face and body stimuli on incongruent trials but not on congruent trials. Collectively, our results provide some evidence that both adults and children may process emotional faces and bodies holistically. Consistent with the pattern of results for congruency effects, the magnitude of the effect of misalignment varied with the similarity between emotions. Future research is required to further investigate whether or not facial expressions and emotions conveyed by the body are perceived holistically.

Previously, studies investigating emotional face perception - regardless of whether they involved adults or children - presented participants with static photos of faces in isolation. In the natural world, faces are rarely encountered in isolation. In the few studies that have presented faces in context, the perception of emotional facial expressions is altered when paired with an incongruent context. For both adults and 8- year-old children, reaction times increase and accuracy decreases when facial expressions are presented in an incongruent context depicting a similar emotion (e.g., sad face on a fear body) compared to when presented in a congruent context (e.g., sad face on a sad body; Meeren, van Heijnsbergen, & de Gelder, 2005; Mondloch, 2012). This effect is called a congruency effect and does not exist for dissimilar emotions (e.g., happy and sad; Mondloch, 2012). Two models characterize similarity between emotional expressions differently; the emotional seed model bases similarity on physical features, whereas the dimensional model bases similarity on underlying dimensions of valence an . arousal. Study 1 investigated the emergence of an adult-like pattern of congruency effects in pre-school aged children. Using a child-friendly sorting task, we identified the youngest age at which children could accurately sort isolated facial expressions and body postures and then measured whether an incongruent context disrupted the perception of emotional facial expressions. Six-year-old children showed congruency effects for sad/fear but 4-year-old children did not for sad/happy. This pattern of congruency effects is consistent with both models and indicates that an adult-like pattern exists at the youngest age children can reliably sort emotional expressions in isolation. In Study 2, we compared the two models to determine their predictive abilities. The two models make different predictions about the size of congruency effects for three emotions: sad, anger, and fear. The emotional seed model predicts larger congruency effects when sad is paired with either anger or fear compared to when anger and fear are paired with each other. The dimensional model predicts larger congruency effects when anger and fear are paired together compared to when either is paired with sad. In both a speeded and unspeeded task the results failed to support either model, but the pattern of results indicated fearful bodies have a special effect. Fearful bodies reduced accuracy, increased reaction times more than any other posture, and shifted the pattern of errors. To determine whether the results were specific to bodies, we ran the reverse task to determine if faces could disrupt the perception of body postures. This experiment did not produce congruency effects, meaning faces do not influence the perception of body postures. In the final experiment, participants performed a flanker task to determine whether the effect of fearful bodies was specific to faces or whether fearful bodies would also produce a larger effect in an unrelated task in which faces were absent. Reaction times did not differ across trials, meaning fearful bodies' large effect is specific to situations with faces. Collectively, these studies provide novel insights, both developmentally and theoretically, into how emotional faces are perceived in context.

Introduction Cette recherche constitue une étude clinique descriptive, visant à évaluer la douleur durant le traitement orthodontique avec boîtiers auto-ligaturants passifs et actifs. Matériel et méthode L'étude a été effectuée chez 39 patients (18 garçons, 21 filles), âge moyen 14 (entre 11 et 19 ans). Deux types de boîtiers auto-ligaturants ont été utilisés (SPEED n=20 et Damon n=19). Pour évaluer la douleur, un questionnaire a été élaboré par l'équipe de recherche. L’étude comportait 4 phases, c’est-à-dire l’évaluation de la douleur suite à l’insertion des 4 premiers fils orthodontiques du traitement de chaque patient (0.016 Supercable, 016 CuNiTi, 016X022 CuNiTi, 019X025 CuNiTi). Le même questionnaire était utilisé lors de chaque phase et le questionnaire comprenait 6 différents temps (T0: avant l’insertion du fil orthodontique, T1: immédiatement suite à l’insertion du fil, T2: 5h après l’insertion, T3: 24h après l’insertion, T4: 3 jours après l’insertion, T5: une semaine après l’insertion, T6: 4 semaines après l’insertion) suite à l’insertion de chaque fil. L’échelle visuelle analogue (EVA) et la version courte du questionnaire de Saint-Antoine ont été utilisés afin d’évaluer la douleur. Les données des EVA entre les groupes ont été comparées en utilisant le U test Mann-Whitney. Résultats et discussion Pour les deux premiers fils et pour tous les temps étudiés, il n’y avait pas de différence statistiquement significative entre les deux groupes (SPEED et Damon). Cependant, au moment de l’insertion (T0) du troisième fil (016X022 CuNiTi), parmi les patients ayant rapporté de la douleur (SPEED 47.1%, Damon 55.6%), le groupe Damon a rapporté une douleur significativement plus élevée que le groupe SPEED (p=0.018), (EVA moyenne SPEED=14.14±8.55, Damon=33.85±19.64). Trois jours après l’insertion du troisième fil, toujours parmi les patients ayant rapporté de la douleur (SPEED 23.5%, Damon 33.4%), la douleur était significativement plus élevée chez le groupe Damon que chez le groupe SPEED (p=0.008), (EVA moyenne SPEED=8.74±4.87, Damon=25.15±9.69). La plupart des analgésiques ont été pris suite à la pose du premier fil au temps T2 (5h) et T3 (24h). Il n’y avait pas de différence statistiquement significative entre les groupes en ce qui a trait au nombre de patients qui prenaient des analgésiques. La douleur n’a pas affecté le style de vie pour la grande majorité des patients. Les mots descriptifs sensoriels « tiraillement », « étau » et « élancement » et le mot affectif « énervant » étaient le plus souvent utilisés. Conclusion Les patients du groupe Damon ont ressenti significativement plus de douleur que les patients du groupe SPEED à l’insertion du troisième fil et trois jours suite à l’insertion. Plus de patients ont pris des médicaments pour la douleur avec le premier fil et le style de vie n’était pas affecté pour une majorité de patients. « Tiraillement », « étau », « élancement » et « énervant » étaient les mots descriptifs les plus utilisés par les patients pour décrire leur douleur.

La présente thèse de doctorat porte sur la relation entre la perception de la justice organisationnelle, l’émission de comportements inadaptés au travail et la santé psychologique des individus au travail. En plus de développer un outil de mesure des comportements inadaptés au travail et d’entreprendre un processus de validation de celui-ci, le présent travail propose que les comportements inadaptés au travail puissent occuper un rôle soit protecteur ou explicatif dans la relation qui unit la perception de la justice organisationnelle avec la santé psychologique des individus au travail. Au sein de cette thèse, le premier article recense la documentation scientifique quant aux variables de la perception de la justice organisationnelle, de l’émission des comportements inadaptés au travail et de la santé psychologique des individus au travail, ainsi que les liens qui unissent ces variables. Aussi, les modèles conceptuels des rôles modérateur et médiateur des comportements inadaptés au travail sont proposés au sein de la relation entre la perception de la justice organisationnelle et la santé psychologique des individus au travail. Le deuxième article a pour objectif de développer un outil de mesure des comportements inadaptés au travail et de tester ses propriétés psychométriques. Ainsi, des analyses statistiques exploratoires et confirmatoires ont été effectuées. Afin d’appuyer la valeur critériée de l’outil proposé, une analyse corrélationnelle a été réalisée avec le critère de l’adaptation. Certaines valeurs psychométriques de l’outil sont validées par les résultats obtenus. Le troisième article examine empiriquement les modèles conceptuels des rôles anticipés des comportements inadaptés au travail dans la relation entre la perception de la justice organisationnelle et la santé psychologique des individus au travail. La perception de la justice organisationnelle a été vue sous les composantes distributive, procédurale, informationnelle et interpersonnelle. De son côté, la santé psychologique des individus a été observée par le biais des éléments du bien-être et de la détresse psychologique au travail. Les différentes analyses de régressions multiples hiérarchiques ont permis d’observer l’absence du rôle modérateur des comportements inadaptés au travail. Pour sa part, l’utilisation du test de Sobel a démontré la présence du rôle médiateur des comportements inadaptés au travail dans certaines relations. Plus exactement, celles-ci sont la relation entre la justice interpersonnelle et le bien-être psychologique au travail, la relation entre la justice interpersonnelle et la détresse psychologique au travail, ainsi que la relation entre la justice distributive et la détresse psychologique au travail. Finalement, la conclusion de la thèse présente une synthèse des résultats et expose les limites et pistes de recherches futures.

À la suite d’un crime, les victimes vont ressentir différents besoins et celui d’être informé serait fondamental (Baril, 1984). Les recherches ont permis d’établir que les policiers ont un rôle important à jouer dans la transmission des informations aux victimes puisqu’ils sont les premiers acteurs du système pénal avec lesquels celles-ci sont en contact (Laxminarayan, 2013). De plus, la perception des victimes quant à la façon dont elles ont été traitées par les policiers peut avoir un impact significatif sur leur rétablissement psychologique. Cette étude a pour but de mesurer l’effet thérapeutique des interactions entre les victimes et les policiers ainsi que de la transmission des informations aux victimes à la suite d’un crime sur l’état de stress post-traumatique (ÉSPT). Pour ce faire, l’instrument qui a été administré aux participants (n=188) est l’Échelle modifiée des symptômes du trouble de stress post-traumatique. Cet instrument est une version adaptée et validée en français (Guay, Marchand, Iucci et Martin, 2002) de l’échelle MPSS-SR élaborée par Falsetti, Resnick, Resick et Kilpatrick (1993). Cette échelle permet d’évaluer la présence des symptômes de stress post-traumatique en terme de fréquence et de sévérité. Les résultats de l’étude montrent que l’information est un déterminant important d’un traitement juste et la qualité de ce traitement à un effet thérapeutique sur les symptômes de stress post-traumatique. Une discussion des résultats dans une perspective plus globale concernant les théories en victimologie sur la perception de justice, la problématique de la victimisation secondaire et les implications pour les politiques en matière de droits des victimes sera présentée à la fin de cette recherche.

Introduction : L’inconfort causé par les appareils orthodontiques peut significativement affecter la coopération des patients dans leur traitement. La douleur, ainsi que la détérioration de la fonction (mastication, élocution) sont reconnus comme les déterminants majeurs de la coopération des patients traités par appareils amovibles. Invisalign® se positionne comme une alternative esthétique aux multiples inconforts observés lors des traitements fixes avec boîtiers. À ce jour, peu d’études ont cherché à comparer la douleur (quantitativement et qualitativement) perçue entre cette technique et celle avec boîtiers fixes sur une longue période. Objectif : L’objectif de la présente étude est d’évaluer la douleur ressentie par les patients qui suivent un traitement orthodontique avec coquilles correctrices Invisalign® et de la comparer avec celle des patients qui suivent un traitement orthodontique conventionnel avec des boîtiers fixes. Matériels et Méthodes: L’étude compte 70 patients (29 garçons, 41 filles), moyenne d’âge de 16 ans [11 à 30]. Les trois sous-groupes sont Invisalign® (n=31), boîtiers Damon (n=19) et boîtiers Speed (n=20). Les groupes avec boîtiers (Damon et Speed) sont les 2 groupes de l’étude menée au sein de la clinique d’Orthodontie de l’Université de Montréal en 2011 qui comparait la perception de la douleur durant le traitement orthodontique entre boîtiers auto-ligaturants passifs et actifs. L’étude a été organisée en 4 phases correspondant à l’insertion des 4 premiers fils pour les groupes avec boîtiers (Phase 1: 0,016" Supercable, Phase 2: 0,016" CuNiTi, Phase 3: 0,016"x0,022" CuNiTi, Phase 4: 0,019"x0,025" CuNiTi) et à l’insertion des coquilles 1, 4, 7 et 10 pour le groupe Invisalign®. À l’aide d’un questionnaire, l’étude évalue pour chaque phase l’ampleur (grâce à une échelle visuelle analogue EVA), la durée et la localisation de la douleur à 6 différents points (T1: immédiatement après l’insertion, T2: 5h après, T3: 24h après, T4: 3 jours après, T5: une semaine après, T6: 2 semaines après). Résultats: À T1Ph3 le pourcentage de patients rapportant de la douleur était plus élevé avec Damon qu’avec Invisalign® (p=0,032) (Damon=55,6% ; Invisalign®=23,3%) mais il n’y avait pas de différence avec le groupe Speed (p=0,114). Les patients avec Invisalign® rapportaient significativement moins d’irritation des tissus mous (muqueuses, gencives) que les patients avec des boîtiers. Pour les résultats des EVA, les différences étaient statistiquement significatives à 2 temps : T3Ph1 (Médiane Invisalign®=33,31, Médiane Speed=49,47; p=0,025) et T3Ph4 (Médiane Invisalign®=13,15, Médiane Damon=27,28; p=0,014). Pour la majorité des patients la douleur ne nécessitait pas la prise de médicament et il n’y avait pas de différence significative entre les groupes sur ce point. La qualité de vie était légèrement affectée lors de la première phase et moindrement pour le groupe Invisalign® que pour les groupes avec boîtiers. Pour les patients Invisalign®, la douleur atteignait son niveau le plus élevé entre 5 et 24 heures après l’insertion de la première coquille, et diminuait en intensité et en durée à chaque phase. Conclusion: La perception de la douleur lors d’un traitement orthodontique avec Invisalign® est inférieure à celle ressentie lors d’un traitement avec des boîtiers fixes. Cette méthode de traitement est donc une thérapie attirante pour les patients désirant un traitement esthétique et relativement confortable.

This study documents recovery status and symptom changes in a one-year follow-up of sexually abused (SA) adolescent girls in child protection services in the province of Québec, Canada. Sixteen French-speaking participants were interviewed using the Multidimensional Trauma Recovery and Resiliency Interview (MTRR-I), which was in turn rated by interviewers using the companion rating scale, the MTRR, and completed questionnaires assessing symptoms, types of maltreatment endured and services received. Participants were between the ages of 13 and 17 years (M = 15.2 years) when first interviewed and had experienced severe sexual abuses. Analyses of one-year follow-up data revealed statistically significant changes towards better functioning on multiple domains and less symptomatology for a majority of the girls interviewed. The recovery status of a minority of research participants seems to have worsened in the interval. The discussion considers these findings and addresses relevancy of the MTRR measures in cases of SA adolescents.

Objetivo: Determinar condiciones laborales de los trabajadores de cuatro hospitales de primer nivel y dos de segundo nivel en el departamento del Quindío - Colombia 2012. Metodología: Se realizó un estudio descriptivo de corte transversal con una muestra de 577 trabajadores del sector sanitario de cuatro hospitales de primer nivel y dos de segundo nivel en el departamento de Quindío – Colombia mediante la recolección de datos demográficos y la aplicación de las siguientes encuestas: “Encuesta Nacional de Condiciones de Trabajo” del Instituto Nacional de Seguridad e Higiene en el Trabajo de España (INSHT), en su versión validada para el idioma español: “Irritation Index”. Con fines de analizar la información obtenida se creó una base de datos con base en lo contenido en las encuestas válidas y se realizaron tablas dinámicas en Excel Resultados: participaron 577 trabajadores hospitalarios, encontrándose un 72% de personal femenino y un 28% de personal masculino con una relación H:M 2:6. De la población total encuestada, un 72% corresponde a trabajadores del área asistencial y un 28% al área administrativa. Se encontró una alta percepción de riesgo ergonómico (manejo de cargas, 81%, movimientos repetitivos 91%, posturas forzadas, 49%). Los síntomas osteomusculares referidos fueron: dolor cervical 20%, dolor en región dorsal media 17%, dolor en el hombro 62%, dolor en muñeca 27% y dolor en codo 10%. En la percepción de carga mental y factores de riesgo psicosocial se observó que el 92% de los trabajadores requiere un alto nivel de atención en la ejecución de sus tareas, el 77%, debe atender varias tareas al mismo tiempo, el 52% realiza tarea complejas, el 49% ve necesario esconder sus emociones en el sitio de trabajo, el 13% considera que su trabajo es excesivo, el 43% manifiesta la necesidad de trabajar rápido en el desarrollo de sus funciones, el 69% trabaja con plazos estrictos muy cortos el66% considera que el ritmo de trabajo está determinado por plazos temporales a cumplir. Por otro lado se encuentra una adecuada percepción de la autonomía (93-94%) en la escogencia del método de trabajo, ritmo de trabajo, establecimiento del orden de las tareas a cumplir. En general las relaciones interpersonales son percibidas de manera positiva encontrándose que el 98% recibe ayuda de sus compañeros y el 97% afirma contar con la ayuda de sus superiores. En cuanto a la violencia física en el lugar de trabajo se encuentra que un 6 % ha sido víctima de agresión por parte de personas ajenas al lugar de trabajo. En lo concerniente al percepción de la salud física, el 48% refiere un óptimo estado de salud, mientras que en lo referente a la salud mental se encuentra más frecuentemente alteraciones del sueño (20%), sensación de tensión (20%), tristeza y/o depresión (13%), dificultad para desconectarse del trabajo (15%). Discusión: En la población estudiada se encontró una alta percepción de condiciones ergonómicas inadecuadas dadas por posturas forzadas, manipulación de cargas y movimientos repetitivos, así como exposición a riesgo biológico y factores de riesgo psicosocial. Resulta importante destacar que los hallazgos obtenidos reflejan lo reportado en la literatura internacional y dejan de manifiesto la importancia de reflexionar sobre la necesidad de identificar los riesgos, sensibilizar a la población y de priorizar las actuaciones preventivas.

Este proyecto de investigación busca usar un sistema de cómputo basado en modelación por agentes para medir la percepción de marca de una organización en una población heterogénea. Se espera proporcionar información que permita dar soluciones a una organización acerca del comportamiento de sus consumidores y la asociada percepción de marca. El propósito de este sistema es el de modelar el proceso de percepción-razonamiento-acción para simular un proceso de razonamiento como el resultado de una acumulación de percepciones que resultan en las acciones del consumidor. Este resultado definirá la aceptación de marca o el rechazo del consumidor hacia la empresa. Se realizó un proceso de recolección información acerca de una organización específica en el campo de marketing. Después de compilar y procesar la información obtenida de la empresa, el análisis de la percepción de marca es aplicado mediante procesos de simulación. Los resultados del experimento son emitidos a la organización mediante un informe basado en conclusiones y recomendaciones a nivel de marketing para mejorar la percepción de marca por parte de los consumidores.
