Corrupção nas organizações privadas: análise da percepção moral segundo gênero, idade e grau de instrução

A corrupção organizacional é um fenômeno de natureza sistêmica, pode ser abordada de muitas formas e, entre essas, na óptica da literatura sobre compliance, é entendida como a reflexão sobre as causas e a mitigação da corrupção, bem como sobre os instrumentos para a promoção de ambientes éticos. Na base da compliance está a percepção moral do indivíduo quando exposto aos dilemas éticos. O objetivo no presente trabalho é avaliar o impacto do nível de instrução, da idade e do gênero na percepção moral nas organizações. Para essa finalidade, são utilizados dados secundários, cedidos pela ICTS Global, empresa internacional especializada em redução de riscos ao patrimônio, reputação, informações e vida humana. Realizam-se análises estatísticas exploratórias procurando as relações entre as variáveis indicadoras do índice de análise de aderência à ética empresarial (AAEE) da ICTS Global. Trata-se de análise descritiva baseada em amostra não probabilística por conveniência, realizada entre os anos de 2004 e 2008, com funcionários e candidatos de 74 empresas privadas situadas no Brasil; o número final de indivíduos pesquisados totalizou 7.574. Os resultados indicam que a variável instrução exerce maior influência nos indicadores de percepção moral: quanto menor o grau de instrução, menor a percepção do que é errado. Na análise detalhada dos indicadores de percepção moral, os resultados mostram diferenças comparativas interessantes conforme os perfis dos profissionais e as variáveis analisadas (gênero, idade e grau de instrução).

Por que ocorre? Como lidar? A percepção de professores de graduação em Administração sobre o assédio moral

Tem-se observado em muitas pesquisas que o assédio moral do aluno para com o professor tem sido incrementado com o processo de mercantilização do ensino superior. Tal processo insere-se num cenário de desvalorização da figura do professor e de exaltação da concepção do aluno-cliente. Nesse sentido, abre-se espaço para práticas de assédio moral na relação aluno-professor. O propósito neste artigo é compreender por que acontece o assédio moral no vetor aluno-professor e o que pode ser feito para que esse comportamento seja evitado. Para cumprir o objetivo da investigação, foram coletados e analisados, pelo método do discurso do sujeito coletivo (DSC) de caráter qualiquantitativo, os depoimentos provenientes de 51 questionários respondidos por professores universitários. A análise das respostas dos professores universitários às questões de pesquisa oferece uma percepção do por quê da ocorrência do assédio moral aluno-professor na visão dos pesquisados, os quais identificam motivos que vão desde valores sociais não apreendidos até a mercantilização do ensino. A partir das respostas, verificam-se possibilidades de ação que apontam prioritariamente a discussão institucional como meio de suporte à vítima e como alicerce para ações preventivas, dentre outras atitudes individuais que influenciam positivamente esse tipo de assédio, e mesmo a disputa judicial como última instância para a solução do problema.

Dynamic modelling of an underwater vehicle

Nessie is an Autonomous Underwater Vehicle (AUV) created by a team of students in the Heriot Watt University to compete in the Student Autonomous Underwater Competition, Europe (SAUC-E) in August 2006. The main objective of the project is to find the dynamic equation of the robot, dynamic model. With it, the behaviour of the robot will be easier to understand and movement tests will be available by computer without the need of the robot, what is a way to save time, batteries, money and the robot from water inside itself. The object of the second part in this project is setting a control system for Nessie by using the model

The role of energetic value in dynamic brain response adaptation during repeated food image viewing.

The repeated presentation of simple objects as well as biologically salient objects can cause the adaptation of behavioral and neural responses during the visual categorization of these objects. Mechanisms of response adaptation during repeated food viewing are of particular interest for better understanding food intake beyond energetic needs. Here, we measured visual evoked potentials (VEPs) and conducted neural source estimations to initial and repeated presentations of high-energy and low-energy foods as well as non-food images. The results of our study show that the behavioral and neural responses to food and food-related objects are not uniformly affected by repetition. While the repetition of images displaying low-energy foods and non-food modulated VEPs as well as their underlying neural sources and increased behavioral categorization accuracy, the responses to high-energy images remained largely invariant between initial and repeated encounters. Brain mechanisms when viewing images of high-energy foods thus appear less susceptible to repetition effects than responses to low-energy and non-food images. This finding is likely related to the superior reward value of high-energy foods and might be one reason why in particular high-energetic foods are indulged although potentially leading to detrimental health consequences.

When to initiate combined antiretroviral therapy to reduce mortality and AIDS-defining illness in HIV-infected persons in developed countries: an observational study.

BACKGROUND: Most clinical guidelines recommend that AIDS-free, HIV-infected persons with CD4 cell counts below 0.350 × 10(9) cells/L initiate combined antiretroviral therapy (cART), but the optimal CD4 cell count at which cART should be initiated remains a matter of debate. OBJECTIVE: To identify the optimal CD4 cell count at which cART should be initiated. DESIGN: Prospective observational data from the HIV-CAUSAL Collaboration and dynamic marginal structural models were used to compare cART initiation strategies for CD4 thresholds between 0.200 and 0.500 × 10(9) cells/L. SETTING: HIV clinics in Europe and the Veterans Health Administration system in the United States. PATIENTS: 20, 971 HIV-infected, therapy-naive persons with baseline CD4 cell counts at or above 0.500 × 10(9) cells/L and no previous AIDS-defining illnesses, of whom 8392 had a CD4 cell count that decreased into the range of 0.200 to 0.499 × 10(9) cells/L and were included in the analysis. MEASUREMENTS: Hazard ratios and survival proportions for all-cause mortality and a combined end point of AIDS-defining illness or death. RESULTS: Compared with initiating cART at the CD4 cell count threshold of 0.500 × 10(9) cells/L, the mortality hazard ratio was 1.01 (95% CI, 0.84 to 1.22) for the 0.350 threshold and 1.20 (CI, 0.97 to 1.48) for the 0.200 threshold. The corresponding hazard ratios were 1.38 (CI, 1.23 to 1.56) and 1.90 (CI, 1.67 to 2.15), respectively, for the combined end point of AIDS-defining illness or death. Limitations: CD4 cell count at cART initiation was not randomized. Residual confounding may exist. CONCLUSION: Initiation of cART at a threshold CD4 count of 0.500 × 10(9) cells/L increases AIDS-free survival. However, mortality did not vary substantially with the use of CD4 thresholds between 0.300 and 0.500 × 10(9) cells/L.

Change in defense mechanisms and coping over the course of short-term dynamic psychotherapy for adjustment disorder.

Short-term dynamic psychotherapy (STDP) has rarely been investigated with regard to its underlying mechanisms of change, even if psychoanalytic theory informs us about several potential putative mechanisms of change in patients. Change in overall defensive functioning is one. In this study, we explored the role of overall defensive functioning, by comparing it on the process level with the neighbouring concept of overall coping functioning. A total of N=32 patients, mainly presenting adjustment disorder, were included in the study. The patients underwent STDP up to 40 sessions; three sessions per psychotherapy were transcribed and analyzed by using two observer-rating scales: Defense Mechanism Rating Scales (Perry, 1990) and Coping Action Patterns (Perry, Drapeau, Dunkley, & Blake, 2005). Hierarchical linear modeling was applied to model the change over the course of therapy and relate it to outcome. Results suggest that STDP has an effect on the target variable of overall defensive functioning, which was absent for overall coping functioning. Links with outcome confirm the importance of the effect. These results are discussed from methodological and clinical viewpoints.

Fault diagnosis by refining the parameter uncertainty space of nonlinear dynamic systems

This paper deals with fault detection and isolation problems for nonlinear dynamic systems. Both problems are stated as constraint satisfaction problems (CSP) and solved using consistency techniques. The main contribution is the isolation method based on consistency techniques and uncertainty space refining of interval parameters. The major advantage of this method is that the isolation speed is fast even taking into account uncertainty in parameters, measurements, and model errors. Interval calculations bring independence from the assumption of monotony considered by several approaches for fault isolation which are based on observers. An application to a well known alcoholic fermentation process model is presented

Dynamic diagnosis based on interval analytical redundancy relations and signs of the symptoms

A model-based approach for fault diagnosis is proposed, where the fault detection is based on checking the consistencyof the Analytical Redundancy Relations (ARRs) using an interval tool. The tool takes into account the uncertainty in theparameters and the measurements using intervals. Faults are explicitly included in the model, which allows for the exploitation of additional information. This information is obtained from partial derivatives computed from the ARRs. The signs in the residuals are used to prune the candidate space when performing the fault diagnosis task. The method is illustrated using a two-tank example, in which these aspects are shown to have an impact on the diagnosis and fault discrimination, since the proposed method goes beyond the structural methods
