Emociones y toma de decisiones éticas: desarrollo e implicaciones para la empresa

Los líderes organizacionales se deben enfrentar a retos ambientales del mundo de los negocios y diversas presiones que los ponen día a día en un alto riesgo ético. Sortear dichos riesgos ha demandado cambios sustanciales en las dinámicas de las organizaciones contemporáneas, por lo que las exigencias a los directivos de tomar decisiones acertadas en situaciones de alta complejidad moral son cada vez mayores. Estas decisiones involucran un comportamiento ético de quien las toma, lo cual a su vez está mediado por sus emociones.

Representaciones sociales de la medicina complementaria y alternativa (MCA) para el cáncer en estudiantes universitarios de carreras de ciencias de la salud

Se realizó un estudio cualitativo exploratorio con estudiantes de carreras de Ciencias de la Salud con el objetivo de comprender las representaciones sociales que tienen acerca de la Medicina Complementaria y Alternativa (MCA) para el cáncer. Se desarrollaron grupos focales y la información obtenida fue analizada a través del Análisis Temático e interpretada con base en la Teoría de las Representaciones Sociales. Se encontraron diversas representaciones sociales asociadas con la definición, los objetivos, los tratamientos, la eficacia, las fuentes de información y el origen de la MCA. En conclusión se evidenció una alta tendencia a la aceptación y a la manifestación de una actitud positiva, aunque ambivalente frente a la MCA, además de un desconocimiento por la diferenciación conceptual entre este tipo de Medicina y la Medicina Popular. La cultura y las creencias sociales predominan en las representaciones sociales que tienen los estudiantes de la MCA para el cáncer, pese a su formación académica.

Eficacia de la estimulación magnética transcraneal en la disminución de severidad en el trastorno depresivo mayor en monoterapia y coadyuvante comparado con tratamientos farmacológicos. Revisión sistemática y meta-análisis

Resumen Introducción Una posible opción de tratamiento para el manejo del trastorno depresivo mayor (TDM) es la estimulación magnética transcraneal (EMT) que ha mostrado propiedades antidepresivas superiores al placebo con un buen perfil de seguridad. El objetivo del presente trabajo es determinar la reducción en la severidad del TDM y la proporción de eventos adversos (EA) en pacientes con TDM refractario y no refractario, posterior al uso de EMT administrada en monoterapia o tratamiento coadyuvante comparado con terapia farmacológica. Metodología Se planteó una pregunta PICOT de la cual se realizó una búsqueda sistemática de estudios clínicos en las bases de datos Medline, EMBASE y Cochrane. Dos investigadores en forma independiente realizaron la selección de artículos, evaluación de calidad con la herramienta de la colaboración Cochrane y extracción de datos. Se extrajeron datos de eficacia como tasa de respuesta, porcentaje de remisión, calidad de vida, diminución sintomática del trastorno depresivo mayor en la escala de Hamilton y capacidad funcional. Igualmente, proporción de pacientes con EA. Se realizó un meta-análisis de estas variables teniendo en cuenta la heterogeneidad. Resultados La presente revisión sistemática incluyó 26 estudios clínicos aleatorizados de baja calidad metodológica mostrando que la EMT presentó una eficacia superior cuando es usada como coadyuvante a las terapias con que venían siendo tratados los pacientes con TDM refractario y no refractario en los desenlaces de tasa de respuesta y porcentaje de remisión. En el caso de intervenciones farmacológicas específicas, la EMT presento eficacia similar, tanto en terapia coadyuvante como en monoterapia comparado con las intervenciones farmacológicas. En cuanto a seguridad, la EMT presenta un buen perfil de seguridad debido a que en todos los escenarios estudiados los EA fueron no serios y baja frecuencia Conclusiones La evidencia disponible sugiere que la EMT mostró ser efectivo y seguro para el manejo del TDM refractario y no refractario. Sin embargo, la evidencia es débil por lo tanto se necesita mayor investigación clínica que soporte su uso.

Projeto eco : análise da influência da atividade física na ansiedade e depressão em indivíduos com obesidade severa

A obesidade é, hoje em dia, considerada um transtorno multifatorial, ou seja, resultante de diversos fatores: bio-psico-sociais. Sendo que os fatores psiquiátricos tais como a ansiedade e a depressão, têm vindo a ter cada vez mais importância, existindo fortes evidências em como a obesidade não é só um transtorno orgânico. Deste modo, torna-se fundamental perceber qual o efeito que a Atividade Física (AF) e o exercício podem ter em transtornos tais com a depressão e a ansiedade, em indivíduos com obesidade severa. Com a realização deste estágio pretendeu-se desenvolver diferentes estratégias de intervenção com este tipo de população, no que diz respeito à prescrição e planeamento de sessões teórico-práticas, consultas de prescrição de exercício e também averiguar qual a influência que a Atividade Física pode ter nos sintomas de Ansiedade e Depressão, em indivíduos com obesidade severa. Foi realizada uma revisão sistemática da literatura na qual se investigou o efeito que o exercício e a AF podem ter na saúde mental, mais concretamente nos sintomas de ansiedade e depressão neste tipo de população. Dos estudos analisados foi possível concluir que indivíduos que são sujeitos a um programa multidisciplinar que inclui atividade física apresentam melhorias quer no que diz respeito à qualidade de vida (2 estudos) como no que diz respeito à saúde mental (4 estudos). Apesar das diferenças metodológicas entre os estudos, concluiu-se que, de uma forma geral, os programas que incluem atividade física, mais especificamente 2 a 3 horas por semana de exercício aeróbio de intensidade moderada a vigorosa, levam a melhorias consideráveis na saúde mental, nos níveis de depressão e de ansiedade. Relativamente às sessões teórico-práticas realizadas, os resultados obtidos com a intervenção realizada não foram significativos tanto no que diz respeito aos sintomas de ansiedade tanto como os de depressão. No que diz respeito às consultas realizadas no Hospital de Santa Maria, foi possível concluir que os utentes avaliados apresentavam na sua maioria comportamentos sedentários. No entanto, apenas um utente foi avaliado pela segunda vez tendo sido reportadas algumas melhorias no que diz respeito à capacidade cardiovascular do primeiro para o segundo momento de avaliação.

Orientação sexual como tema transversal em escolas públicas de Curralinhos-PI

Este estudo objetivou analisar a prática docente relacionada à orientação sexual enquanto tema transversal em escolas públicas no munícipio de Curralinhos-PI, e neste encalço, identificar as formas de práticas docentes relacionadas à orientação sexual enquanto tema transversal; caracterizar os fatores condicionantes para a realização da abordagem da orientação sexual em sala de aula; verificar a contribuição das oficinas do Programa Saúde e Prevenção na Escola (SPE) na formação continuada da prática docente e, a percepção de professores e alunos, quanto à relevância da abordagem do tema em questão de forma sistemática e transversal nas referidas escolas. Trata-se de um estudo com abordagem qualitativa e quantitativa com função de complementaridade, realizada em duas escolas públicas (X e Y) do município de Curralinhos-PI, de ensino fundamental e ensino médio, respectivamente, envolvendo uma amostra de 8 (oito) professores, que participaram das oficinas do SPE e 116 alunos, sendo 54 da escola X e 62 da escola Y. Os instrumentos da coleta de dados foram a entrevista e o questionário semiestruturados, originários de um roteiro de questões-guia. A coleta de dados foi realizada no segundo semestre de 2011, nos meses de agosto a setembro. Os resultados apontaram que é grande a necessidade de se discutir e implementar a orientação sexual no espaço escolar, pois embora a maioria dos professores entrevistados reconheçam a importância de se trabalhar a orientação sexual como tema transversal e demonstrarem conhecer esta proposta dos Parâmetros Curriculares Nacionais (PCNs), ainda são difusas as práticas incorporadas em suas atividades pedagógicas. Quanto aos alunos, evidenciaram que ainda se fazem presentes dúvidas e angústias, assim como dificuldades para a lida com o tema da sexualidade.

Effect of micronutrient supplementation on mood in nursing home residents

One third of older people in nursing and/or residential homes have significant symptoms of depression. In younger people, deficiencies in selenium, vitamin C and folate are associated with depression. This study examines the association between micronutrient status and mood before and after supplementation. The objective was to determine whether the administration of selenium, vitamin C and folate improved mood in frail elderly nursing home residents. Mood was assessed using the Hospital Anxiety and Depression rating scale (HAD), and Montgomery-Asberg Depression Rating Scale (MADRS). Micronutrient supplementation was provided for 8 weeks in a double-blinded randomised controlled trial. Significant symptoms of depression (29%) and anxiety (24%) were found at baseline. 67% of patients had low serum concentrations of vitamin C, but no-one was below the reference range for selenium. Depression was significantly associated with selenium levels, but not with folate or vitamin C levels. No individual with a HAD depression score of >= 8, had selenium levels >1.2 mu M. In those patients with higher HAD depression scores, there was a significant reduction in the score and a significant increase in serum selenium levels after 8 weeks of micronutrient supplementation. Placebo group scores were unchanged. This small study concluded that depression was associated with low levels of selenium in frail older individuals. Following 8 weeks of micronutrient supplementation, there was a significant increase in selenium levels and improved symptoms of depression occurred in a subgroup. Copyright (C) 2008 S.

The perception of emotion from body movement in point-light displays of interpersonal dialogue

We examined whether it is possible to identify the emotional content of behaviour from point-light displays where pairs of actors are engaged in interpersonal communication. These actors displayed a series of emotions, which included sadness, anger, joy, disgust, fear, and romantic love. In experiment 1, subjects viewed brief clips of these point-light displays presented the right way up and upside down. In experiment 2, the importance of the interaction between the two figures in the recognition of emotion was examined. Subjects were shown upright versions of (i) the original pairs (dyads), (ii) a single actor (monad), and (iii) a dyad comprising a single actor and his/her mirror image (reflected dyad). In each experiment, the subjects rated the emotional content of the displays by moving a slider along a horizontal scale. All of the emotions received a rating for every clip. In experiment 1, when the displays were upright, the correct emotions were identified in each case except disgust; but, when the displays were inverted, performance was significantly diminished for some ernotions. In experiment 2, the recognition of love and joy was impaired by the absence of the acting partner, and the recognition of sadness, joy, and fear was impaired in the non-veridical (mirror image) displays. These findings both support and extend previous research by showing that biological motion is sufficient for the perception of emotion, although inversion affects performance. Moreover, emotion perception from biological motion can be affected by the veridical or non-veridical social context within the displays.

Reducing contamination by exposure plus safety behaviour

Background and objectives: It has been proposed that the judicious use of safety behaviour can facilitate improvements in the acceptability of cognitive behaviour therapy (CBT). It was decided to explore the possibility of facilitating CBT by introducing a form of safety behaviour.We sought to assess the degree to which Exposure plus Safety Behaviour (E þ SB) is an effective intervention for contamination fears. Methods: A comparison was made between the effects of a control condition (Exposure and Response Prevention; ERP) and an experimental condition (Exposure plus Safety Behaviour; E þ SB) in which each exposure to a contaminant was followed by the use of a hygienic wipe in a sample of (n ¼ 80) undergraduate students. In session one, each participant touched a confirmed contaminant 20 times. After each exposure participants were asked to report their feelings of contamination, fear, disgust, and danger. In the second session, two weeks later, the same procedure was carried out for a further 16 trials. Results: The ERP and the E þ SB conditions both produced large, significant and stable reductions in contamination. Significant reductions in fear, danger and disgust were also reported in both conditions. Limitations: The treatment was provided to an analogue sample and over two sessions. Conclusions: The use of hygienic wipes, the safety behaviour used in this experiment, did not preclude significant reductions in contamination, disgust, fear and danger. If it is replicated and extended over a longer time-frame, this finding may enable practitioners to enhance the acceptability of cognitive behavioural treatments and boost their effectiveness.

Shaping children’s mobilities: expectations of gendered parenting in the English rural idyll

This paper explores the impact of local parenting practices and children's everyday use of public space within two villages in the rural South West of England, an issue that has been underexplored in recent research. Drawing upon the concept of hybridity, it explores the interplay between the social, natural and material in shaping local cultures of rural parenting. The paper begins by drawing upon recent research on parenting in the global North, the gendering of rural space and hybridity to show how these bodies of work can be interlinked to better understand rural parenting practices and norms. Through empirical research that focused on the relationships between gendered parenting strategies, idealised notions of rural motherhood and materiality, the paper explores the diverse ways in which a group of working and middle-class mothers construct and define ideas about their children's lives and mobilities. Whilst dominant discourses of rurality focus upon the idyll, and gendered identities of rural women still remain within the domestic sphere, so we examine how these deeply embedded notions of ‘normality’ can be powerful social tools in rural villages, mobilised through discourses of materiality and anxiety. In our conclusions, we argue that the hybrid integration of the material and social provides a useful framework for understanding the everyday geographies of rural parenting.

An experimental manipulation of responsibility in children: a test of the inflated responsibility model of obsessive-compulsive disorder

The objective of this study was to investigate whether Salkovskis (1985) inflated responsibility model of obsessive-compulsive disorder (OCD) applied to children. In an experimental design, 81 children aged 9– 12 years were randomly allocated to three conditions: an inflated responsibility group, a moderate responsibility group, and a reduced responsibility group. In all groups children were asked to sort sweets according to whether or not they contained nuts. At baseline the groups did not differ on children’s self reported anxiety, depression, obsessive-compulsive symptoms or on inflated responsibility beliefs. The experimental manipulation successfully changed children’s perceptions of responsibility. During the sorting task time taken to complete the task, checking behaviours, hesitations, and anxiety were recorded. There was a significant effect of responsibility level on the behavioural variables of time taken, hesitations and check; as perceived responsibility increased children took longer to complete the task and checked and hesitated more often. There was no between-group difference in children’s self reported state anxiety. The results offer preliminary support for the link between inflated responsibility and increased checking behaviours in children and add to the small but growing literature suggesting that cognitive models of OCD may apply to children.

Exploring unanticipated consequences of strategy amongst stakeholder segments: the case of a European Revenue Service

This article applies FIMIX-PLS segmentation methodology to detect and explore unanticipated reactions to organisational strategy among stakeholder segments. For many large organisations today, the tendency to apply a “one-size-fits-all” strategy to members of a stakeholder population, commonly driven by a desire for simplicity, efficiency and fairness, may actually result in unanticipated consequences amongst specific subgroups within the target population. This study argues that it is critical for organisations to understand the varying and potentially harmful effects of strategic actions across differing, and previously unidentified, segments within a stakeholder population. The case of a European revenue service that currently focuses its strategic actions on building trust and compliant behaviour amongst taxpayers is used as the context for this study. FIMIX-PLS analysis is applied to a sample of 501 individual taxpayers, while a novel PLS-based approach for assessing measurement model invariance that can be applied to both reflective and formative measures is also introduced for the purpose of multi-group comparisons. The findings suggest that individual taxpayers can be split into two equal-sized segments with highly differentiated characteristics and reactions to organisational strategy and communications. Compliant behaviour in the first segment (n = 223), labelled “relationships centred on trust,” is mainly driven through positive service experiences and judgements of competence, while judgements of benevolence lead to the unanticipated reaction of increasing distrust among this group. Conversely, compliant behaviour in the second segment (n = 278), labelled “relationships centred on distrust,” is driven by the reduction of fear and scepticism towards the revenue service, which is achieved through signalling benevolence, reduced enforcement and the lower incidence of negative stories. In this segment, the use of enforcement has the unanticipated and counterproductive effect of ultimately reducing compliant behaviour.

Randomized controlled trial of parent-enhanced CBT compared with individual CBT for obsessive-compulsive disorder in young people

Objective: Obsessive-compulsive disorder (OCD) in young people can be effectively treated with Cognitive Behavior Therapy (CBT). Practice guidelines in the United Kingdom recommend that CBT be delivered with parental or family involvement; however, there is no evidence from randomized trials that this enhances effectiveness. The aim of this trial was to assess if CBT with high parental involvement was more effective than CBT with low parental involvement (individual CBT) in reducing symptoms of OCD. Method: Fifty young people ages 12–17 years with OCD were randomly allocated to individual CBT or parent-enhanced CBT. In parent-enhanced CBT parents attended all treatment sessions; in individual CBT, parents attended only Sessions 1, 7, and the final session. Participants received up to 14 sessions of CBT. Data were analyzed using intent-to-treat and per-protocol methods. The primary outcome measure was the Children’s Yale-Brown Obsessive Compulsion Scale (Scahill et al., 1997). Results: Both forms of CBT significantly reduced symptoms of OCD and anxiety. Change in OCD symptoms was maintained at 6 months. Per-protocol analysis suggested that parent-enhanced CBT may be associated with significantly larger reductions in anxiety symptoms. Conclusions: High and low parental involvement in CBT for OCD in young people were both effective, and there was no evidence that 1 method of delivery was superior on the primary outcome measure. However, this study was small. Future trials should be adequately powered and examine interactions with the age of the young person and comorbid anxiety disorders.

Reduced neural response to reward following 7 days treatment with the cannabinoid CB1 antagonist rimonabant in healthy volunteers

Reduced subjective experience of reward (anhedonia) is a key symptom of major depression. The anti-obesity drug and cannabinoid type 1 receptor (CB(1)) antagonist, rimonabant, is associated with significant rates of depression and anxiety in clinical use and was recently withdrawn from the market because of these adverse effects. Using a functional magnetic resonance imaging (fMRI) model of reward we hypothesized that rimonabant would impair reward processing. Twenty-two healthy participants were randomly allocated to receive rimonabant (20 mg), or placebo, for 7 d in a double-blind, parallel group design. We used fMRI to measure the neural response to rewarding (sight and/or flavour of chocolate) and aversive (sight of mouldy strawberries and/or an unpleasant strawberry taste) stimuli on the final day of drug treatment. Rimonabant reduced the neural response to chocolate stimuli in key reward areas such as the ventral striatum and the orbitofrontal cortex. Rimonabant also decreased neural responses to the aversive stimulus condition in the caudate nucleus and ventral striatum, but increased lateral orbitofrontal activations to the aversive sight and taste of strawberry condition. Our findings are the first to show that the anti-obesity drug rimonabant inhibits the neural processing of rewarding food stimuli in humans. This plausibly underlies its ability to promote weight loss, but may also indicate a mechanism for inducing anhedonia which could lead to the increased risk of depressive symptomatology seen in clinical use. fMRI may be a useful method of screening novel agents for unwanted effects on reward and associated clinical adverse reactions.
