AS DIMENSÕES DA ORGANIZAÇÃO POSITIVA E SEUS IMPACTOS SOBRE O BEMESTAR DOS TRABALHADORES

Atualmente, características organizacionais vêm sendo estudadas sob um prisma diferenciado. Hoje, são pesquisados com maior ênfase os aspectos positivos que possam prover a possibilidade dos trabalhadores nutrirem sentimentos positivos para com suas organizações empregadoras e ao seu trabalho propriamente dito. Os desafios impostos atualmente giram em torno de se buscar identificar características organizacionais positivas que permitam o florescimento do trabalhador. Tais características são postuladas como benéficas tanto às organizações, por resultar em maior produtividade e lucratividade, assim como para promover o bem-estar dos trabalhadores. O objetivo deste estudo foi analisar os impactos que as dimensões da organização positiva exercem sobre o bem-estar dos trabalhadores. O bem-estar dos trabalhadores foi dividido em duas áreas, bem-estar subjetivo (composto por satisfação geral com a vida, afetos positivos e afetos negativos) e bem-estar no trabalho, composto por três dimensões: satisfação no trabalho, envolvimento com o trabalho e comprometimento organizacional afetivo. Organização positiva foi concebida como um construto composto por três dimensões: percepção de suporte organizacional, percepções de justiça organizacional (distributiva e de procedimentos) e confiança do empregado na organização. A amostra foi composta por 200 trabalhadores de diversas empresas do Estado de São Paulo, sendo 55 do sexo masculino e 145 do sexo feminino, solteiros e casados com escolaridade distribuída desde o ensino fundamental completo até pósgraduação completa. O instrumento de coleta de dados foi um questionário auto-aplicável composto por nove escalas que mediram as variáveis do estudo. Os resultados deste trabalho revelaram que bem-estar subjetivo e bem-estar no trabalho guardam relações entre si. Análises de regressão múltipla informaram que as dimensões da organização positiva tiveram impactos maiores sobre bem-estar no trabalho do que bem-estar subjetivo, destacando-se a capacidade de confiança do empregado na organização de prover explicações para o bem-estar de trabalhadores, seja nos domínios da vida pessoal ou no contexto de trabalho. Conforme tais resultados, confiança do empregado na organização, percepções de justiça e de suporte organizacional poderiam ser apontadas como importantes dimensões da organização positiva para promover e proteger o bem-estar dos trabalhadores. Futuros estudos deveriam incluir outras características organizacionais positivas para aumentar a explicação da variância do bem-estar dos trabalhadores

BEM-ESTAR SUBJETIVO E AUTOEFICÁCIA EM DEPENDENTES DE COCAÍNA/CRACK

Este estudo teve por objetivo identificar e descrever associações entre bem-estar subjetivo, construto formado por satisfação geral com a vida e afetos positivos e negativos,e autoeficáciapara abstinência de drogas em dependentes de cocaína/crack em processo de abstinência. Utilizou, para avaliar as variáveis, as Escalas de Afetos Positivos e Negativos, de Satisfação Geral com a Vida, de Autoeficácia para Abstinência de Drogas, de Avaliação para Mudança da Universidade de Rhode Island e um questionário de dados sócio-demográficos e socioculturais. Participaram 70 homens, dependentes de cocaína/crack, jovens e de baixa escolaridade.Eram pessoas de rendimentos de até três salários mínimos (63%), que foram internadas mais de uma vez (65%), autodeclaradas abstinentes no momento da coleta dos dados. Os participantes possuíam níveis médiosde autoeficácia para abstinência de drogas, níveis baixos de bem-estar subjetivo, e estavam satisfeitos com suas vidas. Cálculos de correlação de Pearson revelaram que não há associação entre bem-estar subjetivoe autoeficácia para abstinência de drogas, entre prontidão para mudança no consumo de drogas e bem-estar subjetivo, nem entre prontidão para mudança no consumo de drogas eautoeficácia para abstinência de drogas. Resultados de análise de variância revelaram que não houve diferençasnos níveis de bem-estar subjetivo entreos diferentes os agrupamentos de prontidão para mudanças nem entre as médias de autoeficácia para abstinência de drogas entre os diferentes agrupamentos de prontidão para mudanças no consumo de drogas. A discussão abordou os resultados diante do fato de a internação dos participantes ter sido involuntária ou voluntária, do tempo de internação, do seu estágio de prontidão para mudar seu comportamento de consumo de drogas e das características de seu grupo de abstinência diante da literatura da área. Finalmente, apontou, em conclusão, limitações e agenda de pesquisa futura.

EXPERIÊNCIAS AFETIVAS NO CONTEXTO ORGANIZACIONAL E SEU IMPACTO SOBRE O BEM-ESTAR NO TRABALHO

Em ambiente de elevada pressão, competição e necessidade de criação de diferenciais consistentes que venham contribuir com a longevidade das organizações, nota-se a busca e, às vezes, radicais transformações nos modelos de gestão de negócios e gestão do ser humano no meio empresarial. No campo central dos estudos atuais acerca do comportamento humano e de suas relações com as diversas instituições em que o homem se vê inserido, figuram os esforços voltados à compreensão do papel e valor da contribuição do ser humano ao ambiente de trabalho e fortalecimento das organizações. Crescentes se mostram a preocupação e o entendimento sobre os fatores que impactam o bem-estar geral, o bem-estar no trabalho, a saúde dos trabalhadores e as variáveis emocionais oriundas das relações interpessoais comuns a todo organismo social. A combinação de temas emergentes e ricos em significância como bem-estar no trabalho, satisfação e envolvimento com o trabalho, comprometimento organizacional afetivo, emoções, afetos e sentimentos, caracterizam-se como um vasto e instigante campo de pesquisa para uma adaptação mais ampla do ser humano ao ambiente organizacional. O presente estudo teve como objetivo submeter ao teste empírico as relações entre experiências afetivas no contexto organizacional e três dimensões de bem-estar no trabalho - satisfação no trabalho, envolvimento com o trabalho e comprometimento organizacional afetivo. A amostra foi composta por 253 profissionais de uma indústria metalúrgica de autopeças na grande São Paulo, sendo 213 do sexo masculino e 29 do sexo feminino, com maior freqüência na faixa etária compreendida entre 26 a 30 anos, distribuída entre solteiros e casados. Para a coleta de dados foi utilizado um questionário de auto-preenchimento com quatro escalas que avaliaram afetos positivos e negativos, satisfação no trabalho, envolvimento com o trabalho e comprometimento organizacional afetivo. A análise dos dados foi feita por meio do SPSS, versão 16.0 e diversos sub-programas permitiram realizar análises descritivas bem como calcular modelos de regressão linear para verificar o impacto de afetos positivos e negativos sobre bem-estar no trabalho. Os resultados deste estudo revelaram que o principal preditor das dimensões de bem-estar no trabalho foram os afetos positivos. Assim, parece ser adequado afirmar que bem-estar no trabalho seja um estado psicológico sustentado, em especial, pela vivência de emoções positivas no contexto organizacional. Sugere-se que a promoção da saúde e do bem-estar dentro das organizações sejam focos de estudos futuros, representando valiosa contribuição aos campos de conhecimento da psicologia da saúde e da psicologia organizacional, bem como ao conseqüente fortalecimento dos vínculos entre empresa e trabalhadores.(AU)

Negative data in DEA:a directional distance approach applied to bank branches

This paper is drawn from the use of data envelopment analysis (DEA) in helping a Portuguese bank to manage the performance of its branches. The bank wanted to set targets for the branches on such variables as growth in number of clients, growth in funds deposited and so on. Such variables can take positive and negative values but apart from some exceptions, traditional DEA models have hitherto been restricted to non-negative data. We report on the development of a model to handle unrestricted data in a DEA framework and illustrate the use of this model on data from the bank concerned.

Exchange rate forecasting using a combined parametric and nonparametric self-organising modelling approach

Financial prediction has attracted a lot of interest due to the financial implications that the accurate prediction of financial markets can have. A variety of data driven modellingapproaches have been applied but their performance has produced mixed results. In this study we apply both parametric (neural networks with active neurons) and nonparametric (analog complexing) self-organisingmodelling methods for the daily prediction of the exchangerate market. We also propose acombinedapproach where the parametric and nonparametricself-organising methods are combined sequentially, exploiting the advantages of the individual methods with the aim of improving their performance. The combined method is found to produce promising results and to outperform the individual methods when tested with two exchangerates: the American Dollar and the Deutche Mark against the British Pound.

Trade unions and productivity:the impact of union presence on labour productivity in Korean manufacturing

This thesis examines the theoretical and empirical relationship between trade unions and productivity in the Korean auto and cement manufacturing industries, during the 1980s. It challenges the tenets of the existing debate by stressing the contingent nature of this relationship. In particular this thesis pinpoints inadequacies of econometric analysis as the only method of judging this association between union presence and productivity, because this ignores national and historical industrial relations contexts. Moreover, the polarity between positive and negative views of trade union influences on productivity is seen as needlessly limited, failing as it does to consider the full context of labour-management dynamics within the employment relationship. Empirically, this thesis focuses on the unionism and productivity during two contrasting political periods: the first a time of constraint on union action and the second a period of relative freedom. It examines these periods using a full range of quantitative and qualitative analysis. Of particular significant is the inclusion of attitude surveys of the relationship between the presence of unions and productivity conducted amongst workers, managers and trade union officials. The broad conclusion of the thesis is a rejection of the validity of continuing to examine the relationship between trade unions and productivity without locating this within national and historical industrial relations contexts.

A common rule for integration and suppression of luminance contrast across eyes, space, time, and pattern

Visual perception begins by dissecting the retinal image into millions of small patches for local analyses by local receptive fields. However, image structures extend well beyond these receptive fields and so further processes must be involved in sewing the image fragments back together to derive representations of higher order (more global) structures. To investigate the integration process, we also need to understand the opposite process of suppression. To investigate both processes together, we measured triplets of dipper functions for targets and pedestals involving interdigitated stimulus pairs (A, B). Previous work has shown that summation and suppression operate over the full contrast range for the domains of ocularity and space. Here, we extend that work to include orientation and time domains. Temporal stimuli were 15-Hz counter-phase sine-wave gratings, where A and B were the positive and negative phases of the oscillation, respectively. For orientation, we used orthogonally oriented contrast patches (A, B) whose sum was an isotropic difference of Gaussians. Results from all four domains could be understood within a common framework in which summation operates separately within the numerator and denominator of a contrast gain control equation. This simple arrangement of summation and counter-suppression achieves integration of various stimulus attributes without distorting the underlying contrast code.

Inherited labour hoarding, insiders and employment growth:panel data results : Poland, 1996-2002

Using panel data pertaining to large Polish (non-financial) firms this paper examines the determinants of employment change during the period 1996-2002. Paying particular attention to the asymmetry hypothesis we investigate the impact of own wages, outside wages, output growth, regional characteristics and sectoral affiliation on the evolution of employment. In keeping with the 'right to manage' model we find that employment dynamics are not affected negatively by alternative wages. Furthermore, in contrast to the early transition period, we find evidence that employment levels respond to positive sales growth (in all but state firms). The early literature, (e.g. Kollo, 1998) found that labour hoarding lowered employment elasticities in the presence of positive demand shocks. Our findings suggest that inherited labour hoarding may no longer be a factor. We argue that the present pattern of employment adjustment is better explained by the role of insiders. This tentative conclusion is hinged on the contrasting behaviour of state and privatised companies and the similar behaviour of privatised and new private companies. We conclude that lower responsiveness of employment to both positive and negative changes in revenue in state firms is consistent with the proposition that rent sharing by insiders is stronger in the state sector.

Global and physical self-esteem and body dissatisfaction as mediators of the relationship between weight status and being a victim of bullying

Research has found evidence of a link between being overweight or obese and bullying/peer victimisation, and also between obesity and adjustment problems such as low self-esteem and body dissatisfaction. Studies have also found that adjustment problems can put children at an increased risk of being bullied over time. However, to date the factors that place overweight or obese children at risk of being bullied have been poorly elucidated. Self-report data were collected from a sample of 11-14 year olds (N=376) about their weight status, about their experiences of three different types of bullying (Verbal, Physical and Social), their global self-worth, self-esteem for physical appearance, and body dissatisfaction. Overweight or obese children reported experiencing significantly more verbal and physical (but not social) bullying than their non-overweight peers. Global self-worth, self-esteem for physical appearance and body dissatisfaction each fully mediated the paths between weight status and being a victim of bullying.

Emotions and a Prior Knowledge Representation in Artificial General Intelligence

In this paper a prior knowledge representation for Artificial General Intelligence is proposed based on fuzzy rules using linguistic variables. These linguistic variables may be produced by neural network. Rules may be used for generation of basic emotions – positive and negative, which influence on planning and execution of behavior. The representation of Three Laws of Robotics as such prior knowledge is suggested as highest level of motivation in AGI.

The influence of culture and market orientation on services brands:insights from Irish banking and retail firms

Purpose: This paper aims to examine the influence of the culture of the service firm on its interpretation of the role of the brand and on the development and implementation of its brand values. Design/methodology/approach: A grounded theory approach was used. Interviews were conducted with 20 managers within two leading banking firms in Ireland and two leading grocery retailers in Ireland. Findings: The development of the brand, and its role within the firm, is closely related to the firm's culture. The research shows obstacles and opportunities created by the cultural context of firms wishing to disseminate and embed a set of brand values. The paper presents an "involvement model" of brand values implementation and outlines changes required to implement brand values. Research limitations/implications: The study was bound by access to firms, and managers' availability. The authors sought an insight into the relationship between each firm's culture and its brands. They advocate quantitative research to further investigate the findings within these service sectors and to test proposed antecedents (transformational leadership, employee involvement) and outcomes (employee-based brand equity and consumer-based brand equity) of values adoption. Practical implications: The paper identifies aspects of retail and banking cultures which support or detract from brand development. In particular, it presents the learnings from successful brand values implementation in a clan culture, aspects of which are applicable across other cultures. Originality/value: The paper provides valuable insights into the role of the brand within the service firm and the positive and negative influence of context on brand values and their development and implementation. © Emerald Group Publishing Limited.

Assessment of social cognition in bipolar disorder

Background: Impairment in social cognition may contribute to deficits in social functioning in patients with bipolar disorder (BD). In this study, a complex social cognition task was administered during a neuroimaging session. The behavioral and neural correlates of social cogniton in patients with BD were compared to healthy comparison (HC) subjects. Methods: The task was administered to 25 HC and 25 patients with depression scores ranging from euthymic to depressed at the time of assessment. The task required participants to evaluate situations that were “enhancing” or “threatening” to self-esteem, directed at both oneself, and at other people. For instance, self-esteem enhancing scenarios involved vignettes of activities such as receiving praise during a sports game, while a threatening scenario involved, for example, receiving criticism at a party. Participants were then required to evaluate characters in the scenarios on the basis of positive (“kind”) or negative (“mean”) descriptors. Evaluations were classified from extremely negative to extremely positive. The frequencies of behavioral responses were analyzed using chi-square tests and fMRI data were analyzed using Statistical Parametric Mapping software. Results: Patients differed significantly from HCs in their evaluation of threatening scenarios, directed at both oneself and at other people (p<0.001). Patients had a lower proportion of responses in the neutral category, and more responses in the positive and negative categories, relative to HCs. Neuroimaging results reveal differential patterns of prefrontal-cortical and limbic-subcortical activation in BDs throughout the task [p<0.05 (unc.)]. Conclusions: Findings will contribute to understanding difficulty in interpersonal functioning in patients with BD.

Consumer (dis)satisfaction response to disconfirmation: An examination of the form and the underlying process

The purpose of this dissertation was to examine the form of the consumer satisfaction/dissatisfaction (CS/D) response to disconfirmation. In addition, the cognitive and affective processes underlying the response were also explored. ^ Respondents were provided with information from a prior market research study about a new brand of printer that was being tested. This market research information helped set prior expectations regarding the print quality. Subjects were randomly assigned to an experimental condition that manipulated prior expectations to be either positive or negative. Respondents were then provided with printouts that had performance quality that was either worse (negative disconfirmation) or better (positive disconfirmation) than the prior expectations. In other words, for each level of expectation, respondents were assigned to either positive or negative disconfirmation condition. Subjects were also randomly assigned to a condition of either a high or low level of outcome involvement. ^ Analyses of variance indicated that positive disconfirmation led to a more intense CS/D response than negative disconfirmation, even though there was no significant difference in the intensity for positive and negative disconfirmation. Intensity of CS/D was measured by the distance of the CS/D rating from the midpoint of the scale. The study also found that although outcome involvement did not influence the polarity of the CS/D response, the more direct measures of processing involvement such as the subjects' concentration, attention and care in evaluating the printout did have a significant positive effect on CS/D intensity. ^ Analyses of covariance also indicated that the relationship between the intensity of the CS/D response and the intensity of the disconfirmation was mediated by the intensity of affective responses. Positive disconfirmation led to more intense affective responses than negative disconfirmation. ^
