O Papel de Variáveis Sócio-Demográficas na Tomada de Decisão: Uma Revisão Sistemática sobre o Iowa Gambling Task

O interesse em estudar o papel de variáveis sócio-demográficas no funcionamento cognitivo vem ganhando destaque nos últimos anos. Alguns estudos em neuropsicologia têm mostrado que os fatores sócio-culturais podem ser variáveis importantes na execução de tarefas neuropsicológicas. No entanto, pesquisas com populações saudáveis ainda são recentes na área. O presente artigo teve por objetivo realizar uma revisão sistemática da literatura sobre o papel das variáveis sócio-demográficas escolaridade, idade e gênero no processamento da tomada de decisão avaliado pelo Iowa Gambling Task (IGT). Foram consultadas as bases de dados Medline, Pubmed, Psycinfo e Web of Science, no período de 2000 até 2010, com as seguintes palavras-chaves na sintaxe “education OR schooling AND Iowa Gambling Task” OR “somatic marker” para a variável escolaridade; “age” OR “aging” AND “Iowa Gambling Task” OR “somatic marker” para a variável idade e; “sex” OR “gender” AND “Iowa Gambling Task” OR “somatic marker” para a variável sexo/gênero. Dos abstracts que preenchiam os critérios de inclusão, foram examinados 9 artigos completos para a variável idade, 3 artigos para a variável escolaridade e 6 artigos para a variável gênero. Foram encontrados poucos estudos sobre os fatores idade, escolaridade e gênero e seu impacto no desempenho do IGT. A variável mais estudada foi a idade. A maioria dos estudos mostrou que os adultos jovens tiveram uma melhor aprendizagem ao longo da tarefa do que os adultos idosos, mas não tiveram diferenças quanto ao desempenho total no instrumento. Já quanto ao fator escolaridade poucos estudos foram encontrados e quanto à variável gênero os resultados são contraditórios. Assim, evidencia-se a necessidade de um maior número de investigações com populações saudáveis que esclareçam o papel das variáveis idade, escolaridade e gênero na tomada de decisão mensurada pelo IGT.

Description of the risk factors for relapse in patients diagnosed with severe mental disorders

Objective: The objective of this paper is to describe the population served in mental health institutionsfor mental illness relapse, and the process of identifying risk factors in relapsing patientsdiagnosed with severe mental illness. To this end a descriptive exploratory multicenter, multistageepidemiological study was carried out in mental health institutions of the Order of San Juan deDios Hospital (OHSJD) with hospitalized relapsing patients with a diagnosis of severe mentaldisorder. This study comes from a working network of Psychology professionals in the OHSJDnationwide. Materials and methods: The population sample was of 1005 patients diagnosed withsevere mental disorders, who had presented relapse during the last year. First, the characterizationof the general population was conducted; then, it was narrowed down to the centers, taking intoaccount similarities and differences found according to the clinical and demographic variables.Results: Major risk factors for relapse found in patients diagnosed with severe mental disorderswere: having between 38 and 58 years of age, being female, single, graduates, unemployed, witha prevalence of bipolar affective disorder diagnosis, number of hospitalizations between 2 and10, number of drugs at the time of leaving hospital 2 to 6, with severe difficulties relating withothers and difficulties in adherence to treatment. The need for a caregiver was also found, as wellas a limited number of received psychological interventions. How the system of beliefs affects thedisease and the poor adherence to treatment was identified. Conclusions: These results indicatethe requirement of a design of team intervention strategies, ranging from the assessment team(home), definition of therapeutic action plans (for) and the posthospitalizacion (egress) following.There is a poor support network and limited adherence to comprehensive treatment.

Capacidad aeróbica de bomberos aeronáuticos

Los bomberos aeronáuticos son los encargados de atender todas las emergencias en los aeropuertos y sus cercanías. Estas emergencias incluyen emergencias aéreas, en tierra, eventos con materiales peligros e incendios, entre otros. Su trabajo tiene como características la realización de actividades durante periodos largos de baja intensidad y periodos cortos de alta intensidad. De acuerdo con estas características, es necesario que los bomberos aeronáuticos tengan una buena condición física. El consumo máximo de oxígeno (VO2 máx) como indicador de capacidad aeróbica resulta indispensable para conocer el desempeño de los bomberos en su trabajo. El objetivo de este estudio es determinar la capacidad aeróbica de los bomberos aeronáuticos y sus factores determinantes. Por tanto se desarrolló un estudio transversal de tipo descriptivo en una muestra de 23 hombres bomberos aeronáuticos. Se obtuvo información acerca de sus variables socio-demográficas, se determinó el VO2 máx y umbral ventilatorio mediante análisis de gases espirados durante un protocolo de ejercicio máximo sobre tapiz rodante, se evaluó la composición corporal mediante adipometría y se determinó el nivel de actividad física mediante el cuestionario internacional de actividad física IPAQ. Se encontró que la muestra tenia una edad de 32,6 ± 4,8 años, peso de 78,4 ± 9,8 kg, porcentaje de grasa de 14,8 ± 3,8 %, índice de masa corporal de 25,7 ± 2,7 y VO2máx de 44,6 ± 6. No se encontraron cambios significativos del VO2máx con la edad, pero si con la actividad física, porcentaje de grasa e índice de masa corporal. Se sugiere que el entrenamiento de los bomberos aeronáuticos durante su jornada laboral sea de intervalos de alta intensidad y que se monitorice su nivel de actividad física y composición corporal.

How do inequality affect tax morale in Latin America and Caribbean?

Latin America is well known as an inequitable region. As it is recognized, inequality and corruption perception weaken the way that political institutions works and the democratic system. Focusing on Latin American and Caribbean countries, this paper analyzes what are the elements shaping tax morale. In particular, how the context influences ethical grounds decisions such as the predisposition to pay taxes is analyzed, using the survey carried out in 2005 by Latinobarometro. The objective is to analyze how country performance determines tax morale. To do so, four probitmodels are estimated using Gini index, Transparency International Corruption Perception Index and Gross Domestic Product per capita (GDPpc) as explanatory variables. As expected we found that some socio-demographic variables play a relevant role. Interestingly, we also found that, in this attitude, LAC countries do not register a gender bias. However, those are not our main contributions to the literature on the field. The most important results are linked to: 1) the levelmatters, GDPpc increases the probability of people having tax morale, 2) moreover, income distributionalso influence on tax morale but in opposite direction and 3) corruption perception also reduces tax morale. Those results show that the quality of institutions matters and therefore, the way that democracy works play a relevant role.

Satisfação dos profissionais docentes da escola Conde de Oeiras

O interesse e a escolha do tema satisfação dos profissionais docentes acontece porque a satisfação profissional influencia por um lado o trabalhador ao nível da saúde e bem-estar, e por outro a organização, uma vez que associados à satisfação estão aspectos tão importantes como eficácia, produtividade, clima e abandono. No caso dos professores, o mal-estar vai afectar não só os docentes como também os alunos, influenciando assim negativamente o processo de ensino-aprendizagem. O objectivo deste estudo consiste em identificar quais os factores que contribuem para a satisfação e insatisfação dos professores da Escola Conde de Oeiras, analisando também a influencia de variáveis sócio-demográficas como os anos de experiencia e o ciclo de ensino leccionado. Para tal foram utilizados os seguintes instrumentos: - o Questionário de Satisfação Profissional dos Professores (TJSQ); - e o Questionário de Satisfação Geral no Trabalho. Através dos resultados obtidos é possível concluir que, de uma forma geral os professores desta escola se encontram satisfeitos face à sua actividade profissional e que não a desejam abandonar, no entanto na dimensão recompensas pessoais existe algum mal-estar, confirmando assim a teoria de Herzeberg que afirma, que a insatisfação dos professores decorre de motivos sócio-políticos.

Modelling risk perception and trust in food safety information within the theory of planned behaviour

This study suggests a statistical strategy for explaining how food purchasing intentions are influenced by different levels of risk perception and trust in food safety information. The modelling process is based on Ajzen's Theory of Planned Behaviour and includes trust and risk perception as additional explanatory factors. Interaction and endogeneity across these determinants is explored through a system of simultaneous equations, while the SPARTA equation is estimated through an ordered probit model. Furthermore, parameters are allowed to vary as a function of socio-demographic variables. The application explores chicken purchasing intentions both in a standard situation and conditional to an hypothetical salmonella scare. Data were collected through a nationally representative UK wide survey of 533 UK respondents in face-to-face, in-home interviews. Empirical findings show that interactions exist among the determinants of planned behaviour and socio-demographic variables improve the model's performance. Attitudes emerge as the key determinant of intention to purchase chicken, while trust in food safety information provided by media reduces the likelihood to purchase. (C) 2006 Elsevier Ltd.

Food scares and trust: A European study

The complex interactions between the determinants of food purchase under risk are explored using the SPARTA model, based on the theory of planned behaviour, and estimated through a combination of multivariate statistical techniques. The application investigates chicken consumption choices in two scenarios: ( a) a 'standard' purchasing situation; and (b) following a hypothetical Salmonella scare. The data are from a nationally representative survey of 2,725 respondents from five European countries: France, Germany, Italy, the Netherlands and the United Kingdom. Results show that the effects and interactions of behavioural determinants vary significantly within Europe. Only in the case of a food scare do risk perceptions and trust come into play. The policy priority should be on building and maintaining trust in food and health authorities and research institutions, while food chain actors could mitigate the consequences of a food scare through public trust. No relationship is found between socio-demographic variables and consumer trust in food safety information.

An evaluation of the UK Food Standards Agency's salt campaign

Excessive salt intake is linked to cardiovascular disease and several other health problems around the world. The UK Food Standards Agency initiated a campaign at the end of 2004 to reduce salt intake in the population. There is disagreement over whether the campaign was effective in curbing salt intake or not. We provide fresh evidence on the impact of the campaign, by using data on spot urinary sodium readings and socio-demographic variables from the Health Survey for England over 2003–2007 and combining it with food price information from the Expenditure and Food Survey. Aggregating the data into a pseudo-panel, we estimate fixed effects models to examine the trend in salt intake over the period and to deduce the heterogeneous effects of the policy on the intake of socio-demographic groups. Our results are consistent with a previous hypothesis that the campaign reduced salt intakes by approximately 10%. The impact is shown to be stronger among women than among men. Older cohorts of men show a larger response to the salt campaign compared to younger cohorts, while among women, younger cohorts respond more strongly than older cohorts.

Understanding the barriers to real estate investment in developing economies

Baum (2008a) related the number of real estate funds investing in developing economies to simple economic and demographic variables, and showed that, while the popularity of markets was explained by population and GDP per capita, some countries receive more or less investment than the model predicted. Why is this? In this paper we undertake a literature review to identify the barriers which inhibit international real estate investment. We test our initial findings by questioning property investment professionals through semi-structured interviews. By doing this we were able to verify our list of barriers, identify those barriers which are most likely to affect real estate investors, and to indicate whether there are any real estate-specific variables that create barriers which have not received any academic attention. We show that distortions in international capital flows may be explained by a combination of these formal and informal barriers.

The relationship between entrepreneurial marketing and the characteristics of Thai hotels and their managers

Purpose – The purpose of this paper is to explore empirically whether there are meaningful relationships between key entrepreneurial marketing (EM) variables and the demographic characteristics of the organization and its manager. Design/methodology/approach – The data were gathered from a sample of 369 hotels from all regions of Thailand through the use of a postal survey. Several multiple regression models were used to test the relationships in the study. Interaction terms were added to some models to test the moderating effects of major demographic variables on various EM attributes. Findings – The study shows which types of hotels and which types of managers were associated with EM characteristics. The results indicate that demographic characteristics, such as age, size, location, experience, and gender, significantly explain sets of entrepreneurial marketing variables. It was found, for instance, that both a young hotel and a large hotel are positively associated with entrepreneurial marketing, while owner management is positively associated with market orientation and negatively associated with growth aspirations but has no significant relationship with entrepreneurial orientation. Originality/value – The paper provides a comprehensive overview of selected relationships between key EM dimensions in the existing literature. It is suggested that future research involves a more in-depth exploration of some of the relationships found in this study.

A PCR-RFLP assay for gender assignment in the three-toed sloths (Bradypus, Pilosa, Bradypodidae)

The three-toed sloths (Bradypus) are slow-moving arboreal neotropical mammals. Understanding demographic variables (such as sex ratio) of populations is a key for conservation purposes. Nevertheless, gender assignment of Bradypus is particularly challenging because of the lack of sexual dimorphism in infants and in adults, particularly B. torquatus, the most endangered of the three-toed sloths, in which sex is attributed by visual observation of the reproductively active males. Here, we standardized a method for sexing Bradypus individuals using PCR-RFLP of sex-linked genes ZFX/ZFY. This assay was validated with known-gender animals and proved accurate to assign gender on three Bradypus species.

Clinical significance of lifetime panic disorder in the course of bipolar disorder type I

Objectives: The aim of the study was to analyze the impact of lifetime panic disorder (PD) diagnosis in a sample of patients with bipolar disorder type I (BPI), evaluating clinical and demographic variables. Methods: Ninety-five outpatients from the Bipolar Disorder Research Program at the Institute of Psychiatry of the University of Sao Paulo Medical School were enrolled. Twenty-seven BPI patients with PD were compared to 68 BPI patients without any anxiety disorders regarding clinical and demographic variables. Results: Compared to BPI patients without any anxiety disorders, patients with BPI + PD presented significantly higher number of mood episodes (18.9 +/- 13.8 vs 8.5 +/- 7.8; P < .001), depressive episodes (10.8 +/- 8.2 vs 4.6 +/- 4,8; P = .001), and manic episodes (7.4 +/- 7.3 vs 3.6 +/- 3.6; P = .008). Patients with BPI + PD had more frequently a depressive episode as their first one compared to BPI patients without anxiety disorders (94.1% vs 57.5%; P = .011). Patients with BPI + PD had more comorbidity with lifetime diagnosis of drug abuse or dependence (33.3% vs 8.8%; P = .010) and eating disorders (29.6% vs 6.0%; P = .004). Conclusions: The higher number of mood episodes in general presented by patients with BPI + PD when compared with BPI patients without any anxiety disorders, along with the higher frequencies of drug misuse and eating disorders, indicates that PD comorbidity is associated with a poorer Course and outcome of BPI. The higher frequency of depression as the onset mood episode and the higher number of manic episodes in the group with PD may have important treatment implications and should be further investigated.

Fatores relevantes na geração de valor da marca PETROBRAS - um estudo com consumidores do segmento de combustíveis

The main purpose of this study is identify and select the assessment indicators for Brand Equity (BE), in the fuels segment. Within this perspective, we have chosen to assess the influences based on the following attributes: Brand Loyalty (Lealdade à Marca ( LM), Brand Recognition (Conhecimento da Marca ( CM), Perceived Quality (Qualidade Percebida ( QP) and Brand Associations (Associações à Marca ( AM), through perception of consumers in Rio de Janeiro and São Paulo States. Based on deep interviews in the qualitative phase and in surveys, in the quantitative phase, we began the data analysis through Multiple Linear Regression, according to Atilgan et al. (2005) model and Ha (1996). In the first model, the (CM) was considered non-explanatory to (BE¿, and we¿ve chosen to remove it from the following study model. In the final model, besides remaining variables, demographic variables were included, such as: Family Income (Renda Familiar ( RF) and Federation State (Estado da Federação ( EF), as independent variables. The main relevant findings, through perception of consumers, indicated that the (BE) of company analyzed was better ranked in Rio de Janeiro than in São Paulo and, as for the income, higher level classes tend to have less understanding on the value of (BE) of Petrobras BR. The study finish with mentions the contribution of the research and management implication, as well as limitations and suggestions to further researchers.

The influence of materialism on consumption indebtedness in the context of low income consumers from the city of São Paulo

This research is in the domains of materialism, consumer vulnerability and consumption indebtedness, concepts frequently approached in the literature on consumer behavior, macro-marketing and economic psychology. The influence of materialism on consumer indebtedness is investigated within a context that is characterized by poverty and by factors that cause vulnerability, such as high interest rates, limited access to credit and to quality affordable goods. The objectives of this research are: to produce a materialism scale that is well adapted to its environment, characterizing materialism adequately for the population studied; to compare results obtained with results of other studies; and to measure the relationship between materialism, socio-demographic variables, attitude to debt and consumption indebtedness. The primary data used in the analyses were collected from field research carried out in August, 2005 that relied on a probabilistic household sample of 450 low income individuals who live in poor regions of the city of Sao Paulo. The materialism scale, adapted and translated into Portuguese from Richins (2004), proved to be very successful and encourages new work in the area. It was noted that younger adults tend to be more materialistic than older ones; that illiterate adults tend to be less materialistic than those who did literacy courses when they were already adults; and that gender, income and race are not associated with the materialism construct. Among the other results, a logistic regression model was developed in order to distinguish those individuals who have an installment plan payment booklet from those who do not, based on materialism, socio-demographic variables and purchasing and consumer habits. The proposed model confirms materialism as a behavioral variable useful for forecasting the probability of an individual getting into debt in order to consume, in some cases almost doubling the chance of occurrence of this event. Findings confirm the thesis that it is not only adverse economic factors that lead people to get into debt; and that the study of demand for credit for consumption purposes must, of necessity, include variables of a psychological nature. It is suggested that the low income materialistic consumer experiences feelings of powerlessness and exclusion because of the gap that exists between their possessions and their desires. Lines of conduct to combat this marginalization from the consumer society are drawn targeting marketing professionals, public policy makers and vulnerability researchers. Finally, the possibility of new studies involving the materialism construct, which is central to literature on consumer behavior, albeit little used in empirical studies in Brazil, are discussed.
