Estrutura de relacionamento entre instituições de pesquisa do campo de Ciência e Tecnologia no Brasil

Neste estudo, mapeamos a estrutura de relacionamento entre instituições de pesquisa no campo de Ciência e Tecnologia no Brasil, analisando 688 artigos publicados no Enanpad e no Simpósio de Gestão da Inovação Tecnológica, entre 2000 e 2005. Com base em co-autoria, verificamos que o campo se configura como uma grande rede em que mais da metade das instituições está conectada, criando capital social. Ainda, algumas destacam-se por apresentar grande número de colaboradores, por serem pontes entre diferentes grupos e por manterem a durabilidade das relações, havendo indícios de homofilia, cujas localização geográfica e papel institucional condicionam as relações entre pares. Por fim, existe influência da cooperação na produtividade das instituições.

Are public officials really less satisfied than private sector workers?A comparative study in Brazil

This research aims to compare the public and private sectors with regard to satisfaction at work. We conducted a survey with 670 professionals from both sectors in Brazil. The results of variance analysis confirm previous researches indicating that public officials are less satisfied with their work than private sector workers. However, this result does not repeat when we evaluate the satisfaction dimensions. For instance, public officials reported being more satisfied than private sector workers with regard to social environment and work stability. Unexpectedly, the results suggest that there is no difference between these sectors when we analyze the satisfaction with supervision. Therefore, this article is relevant for Brazilian managers, by offering an empirical research on the distinction between public and private. The article also discusses the theoretical implications, since Brazilian findings do not completely support the international literature.

Accountability and co-production of information and control: social observatories and their relationship with government agencies

Abstract:Through the development of a proposal to categorize accountability into four stages - classical, cross-sectional, systemic, and diffused -, this article aims to identify characteristics of co-production of information and socio-political control of public administration in the work of Brazilian social observatories in relationship with government control agencies. The study analyses data from 20 social observatories and, particularly, three experiences of co-production of information and control, based on a systemic perspective on accountability and a model with four categories: Political and cultural; valuing; systemic-organizational, and production. The conclusions summarize characteristics of these practices, specific phases in the accountability processes, as well as the potentialities and challenges of co-production of information and control, which not only influences, but it is also influenced by the accountability system.

Lyme Disease: antibodies against Borrelia burgdorferi in farm workers in Argentina

Lyme Disease is a tick-borne (specially by Ixodes ticks) immune-mediated inflammatory disorder caused by a newly recognize spirochete, Borrelia burgdorferi. Indirect fluorescent antibody (IF) staining methods and enzyme-linked immunosorbent assay are frequently relied upon to confirm Lyme borreliosis infections. Although serologic testing for antibodies has limitations, it is still the only practical means of confirming B. burgdorferi infections. Because we have no previous report of Lyme disease in human inhabitants in Argentina, a study was designed as a seroepidemiologic investigation of the immune response to B. burgdorferi in farm workers of Argentina with arthritis symptoms. Three out of 28 sera were positive (#1,5 and 9). Serum # 1 was positive for Immunoglobulin G at dilution 1:320, serum # 5 and # 9 both to dilution 1:160; while for Immunoglobulin M all (#1, 5 and 9) were positive at low dilution (1:40) using IF. The results showed that antibodies against B. burgdorferi are present in an Argentinian population. Thus caution should be exercised in the clinical interpretation of arthritis until the presence of B. burgdorferi be confirmed by culture in specific media.

HIV/tuberculosis co-infection: a request for a better surveillance

The increasing endemicity of tuberculosis resulting from causes such as immigration, poverty, a declining public health infrastructure and co-infection by HIV/Mycobacterium tuberculosis, is leading to a change in tuberculosis control programmes. One of the main reasons for the resurgence of tuberculosis is HIV infection - the risk of tuberculosis is greater in HIV patients than in the majority of the population as can be seen from numerous research projects. The need for systematic testing for HIV infection in all tuberculosis patients by undertaking confidential HIV tests on admission to a tuberculosis programme is brought out. This measure would increase the number of cases diagnosed and provide data for better surveillance of the co-infection.

Drug abuse among workers in Brazilian regions

OBJECTIVE: Many business organizations in Brazil have adopted drug testing programs in the workplace since 1992. Rehabilitation, rather than layoff and disciplinary measures, has been offered as part of the Brazilian employee assistance programs. The purpose study is to profile drug abuse among company workers of different Brazilian geographical regions. METHODS: Urine samples of 12,700 workers from five geographical regions were tested for the most common illicit drugs of abuse in the country: marijuana, cocaine, and amphetamine. Enzyme multiplied immunoassay technique (EMIT) and gas chromatography coupled with mass spectrometry (GC/MS) were the techniques utilized for urine testing. The distribution of collected urine samples according to geographical regions was: 72.0% southeast, 13.8% northeast, 7.9% south, 5.7% central west and 0.6% north. RESULTS: Of all samples analyzed, 1.8% was found to be positive for drugs: 0.5% from the south region, 1.1% from northeast, 1.2% from central west, 1.3% from north, and 2.2% from southeast. Of these, 59.9% was marijuana, 17.7% cocaine, 14.6% amphetamine, and 7.7% associated drugs. CONCLUSIONS: The distribution of drugs found in the samples shows a regional variation. Marijuana, however, was found in all regions. Cocaine was seen only in central west and southeast regions. Amphetamine was found in northeast, central west, and southeast regions.

The impact of night work on subjective reports of well-being: an exploratory study of health care workers from five nations

OBJECTIVE: To carry out a survey data collection from health care workers in Brazil, Croatia, Poland, Ukraine and the USA with two primary goals: (1) to provide information about which aspects of well-being are most likely to need attention when shiftwork management solutions are being developed, and (2) to explore whether nations are likely to differ with respect to the impacts of night work on the well-being of workers involved in health care work. METHODS: The respondents from each nation were sorted into night worker and non-night worker groups. Worker perceptions of being physically tired, mentally tired, and tense at the end of the workday were examined. Subjective reports of perceived felt age were also studied. For each of these four dependent variables, an ANCOVA analysis was carried out. Hours worked per week, stability of weekly work schedule, and chronological age were the covariates for these analyses. RESULTS: The results clearly support the general proposal that nations differ significantly in worker perceptions of well-being. In addition, perceptions of physical and mental tiredness at the end of the workday were higher for night workers. For the perception of being physically tired at the end of a workday, the manner and degree to which the night shift impacts the workers varies by nation. CONCLUSIONS: Additional research is needed to determine if the nation and work schedule differences observed are related to differences in job tasks, work schedule structure, off-the-job variables, and/or other worker demographic variables.

Job control, job demands, social support at work and health among adolescent workers

OBJECTIVE: To evaluate physical and psychological dimensions of adolescent labor (such as job demands, job control, and social support in the work environment), and their relation to reported body pain, work injuries, sleep duration and daily working hours. METHODS: A total of 354 adolescents attending evening classes at a public school in São Paulo, Brazil, answered questionnaires regarding their living and working conditions (Karasek's Job Content Questionnaire, 1998), and their health status. Data collection took place in April and May 2001. Multiple logistic regression analysis was used to determine relations among variables. RESULTS: Psychological job demands were related to body pain (OR=3.3), higher risk of work injuries (OR=3.0) and reduced sleep duration in weekdays (Monday to Thursday) (p<0.01). Lower decision authority in the workplace (p=0.03) and higher job security (p=0.02) were related to longer daily working hours. CONCLUSIONS: It was concluded that besides physical stressors, psychological factors are to be taken into account when studying adolescent working conditions, as they may be associated with negative job conditions and health effects.

Distribuição espacial da co-infecção M. tuberculosis/HIV no Estado de São Paulo, 1991-2001

OBJETIVO: Avaliar o padrão espacial de incidência de tuberculose na epidemia de Aids, a fim de verificar a influência do espaço físico na causalidade. MÉTODOS: Foram incluídos os casos de Aids notificados ao Ministério da Saúde, entre 1991 e 2001, provenientes do Estado de São Paulo. Os casos foram estratificados em municípios de residência, em regiões de saúde, em categorias de transmissão de Aids, em sexos e em anos do diagnóstico. Um modelo geoestatístico gaussiano foi usado para construir um mapa temático de risco, utilizando a incidência de tuberculose em casos de Aids como variável de resposta. RESULTADOS: A análise exploratória mostrou dois padrões de incidência de Aids: um, para a capital do Estado, e outro, com risco crescente, para os outros municípios. As regiões mais populosas estão sob maiores riscos de transmissão de tuberculose, mostrando um padrão concordante com o padrão de ocupação do território, do leste para o oeste. As regiões de saúde com os maiores coeficientes de incidência de Aids (por 10 mil habitantes) foram Santos (53,5), São José do Rio Preto (43,1), Ribeirão Preto (42,4) e São Paulo (40,3). As regiões de saúde com maiores incidências de tuberculose em casos de Aids foram Santos (44,9%), Franco da Rocha (39,9%), Osasco (39,6%) e São Paulo (38,9%). CONCLUSÕES: Os resultados permitem concluir que as coordenadas geográficas estão associadas ao risco da tuberculose, mas não de Aids.

Co-ocorrência de violência física conjugal e contra filhos em serviços de saúde

OBJETIVO: Apresentar um perfil de ocorrência e co-ocorrência de violência física conjugal e contra filhos em uma população atendida em serviço de saúde, segundo diferentes características socioeconômicas e demográficas. MÉTODOS: Estudo transversal sobre violência familiar e prematuridade, realizado na cidade do Rio de Janeiro, em 2000. Foram elegíveis para a análise os domicílios contendo mulheres vivendo com companheiro e nos quais coabitavam com pelo menos um filho (ou enteado) de até 18 anos (n=205). Condições socioeconômicas, demográficas e relativas aos hábitos de vida da mulher e do companheiro foram consideradas como potenciais preditores de violência. A variável de desfecho foi analisada em quatro níveis: ausência de violência física no domicílio; ocorrência de violência física no casal; contra pelo menos um filho; e coocorrência. Utilizou-se um modelo logito-multinomial para as projeções de prevalências desses matizes de violência segundo os descritores selecionados. RESULTADOS: Os fatores associados ao maior risco do desfecho foram: idade materna >25 anos; companheiro com primeiro grau incompleto, presença de >2 crianças menores de cinco anos no domicílio; e abuso de álcool e drogas ilícitas pelo companheiro. Em domicílios com todas essas características, a estimativa conjunta de prevalência projetada de violência no casal e contra filhos chegou a 90,2%, sendo de 60,6% a de coocorrência. Na ausência desses fatores, as estimativas foram consideravelmente menores (18,9% e 0,2%, respectivamente). CONCLUSÕES: Profissionais de saúde não devem somente atentar à presença de um gradiente situacional, mas também ao fato de que existe paulatinamente mais chance dos agravos violentos acontecerem como um fenômeno englobando todo o grupo familiar.

Clinical and functional aspects of work-related musculoskeletal disorders among active workers

OBJECTIVE: To evaluate musculoskeletal disorders among active industrial workers. METHODS: The study was carried out in São Carlos, Southeastern Brazil, in 2005. One hundred and thirty-four female workers were physically evaluated and answered questions about their physical symptoms, filled out a pain scale and gave responses in the Oswestry Disability Questionnaire, and the Work Ability Index questionnaire. The data were analyzed descriptively, and in correlation tests and through applying logistic regression. The outcome was evaluated in relation to the perceptions of pain, symptoms, physical assessment, ability to work and disability. RESULTS: Clinical evaluations and sick leave presented positive correlations with the subjective variables. The Work Ability Index presented a negative correlation with the physical disability index (r=-0.69). Symptoms reported at the time of the assessment presented a good correlation with the results from the pain scale and the clinical findings. Previous sick leave showed an association with disability (OR=1.13; 95% CI:1.08;1.18). CONCLUSION: Symptom reports and pain scales may be useful for assessing current conditions at the time of evaluating individuals with work-related musculoskeletal disorders, as they are easier to apply. In more severe cases of such injuries, clinical and functional evaluations and questionnaires such as those relating to ability to work and disability are preferable. Precise and specific evaluations of these disorders may contribute towards fairer legal and administrative decisions.

HIV/AIDS risk among female sex workers who use crack in Southern Brazil

OBJECTIVE: To understand the social context of female sex workers who use crack and its impact on HIV/AIDS risk behaviors. METHODODOLOGICAL PROCEDURES: Qualitative study carried out in Foz do Iguaçu, Southern Brazil, in 2003. Twenty-six in-depth interviews and two focus groups were carried out with female commercial sex workers who frequently use crack. In-depth interviews with health providers, community leaders and public policy managers, as well as field observations were also conducted. Transcript data was entered into Atlas.ti software and grounded theory methodology was used to analyze the data and develop a conceptual model as a result of this study. ANALYSIS OF RESULTS: Female sex workers who use crack had low self-perceived HIV risk in spite of being engaged in risky behaviors (e.g. unprotected sex with multiple partners). Physical and sexual violence among clients, occasional and stable partners was widespread jeopardizing negotiation and consistent condom use. According to health providers, community leaders and public policy managers, several female sex workers who use crack are homeless or live in slums, and rarely have access to health services, voluntary counseling and testing, social support, pre-natal and reproductive care. CONCLUSIONS: Female sex workers who use crack experience a plethora of health and social problems, which apparently affect their risks for HIV infection. Low-threshold, user-friendly and gender-tailored interventions should be implemented, in order to increase the access to health and social-support services among this population. Those initiatives might also increase their access to reproductive health in general, and to preventive strategies focusing on HIV/AIDS and other sexually transmitted infections.

Co-infecção por HIV/HCV em hospital universitário de Recife, Brasil

OBJETIVO: Estimar a prevalência do vírus da hepatite C (HCV) e fatores de risco associados com a co-infecção em pessoas soropositivas para HIV. MÉTODOS: Estudo do tipo transversal, descritivo e analítico, com 343 portadores do HIV atendidos em um hospital universitário de Recife (PE), no período de março a dezembro de 2003. Os pacientes foram submetidos a um questionário padronizado sobre os fatores de risco. Nas amostras de soro foram pesquisados o anti-HCV pelo ELISA, o HCV-RNA por meio da RT-PCR e a identificação dos genótipos foi realizada no equipamento ABI377 (PE Biosystems®). As análises estatísticas utilizadas foram a univariada, a multivariada e a regressão logística múltipla. RESULTADOS: A prevalência encontrada para o HCV foi de 4,1% (14/343) pelo ELISA e de 3,2 % (11/343) quando utilizada a RT-PCR. Os genótipos mais freqüentes foram 1b (45%), 3 (33%) e 1a (22%). A faixa etária com maior proporção de co-infectados foi a de 30 a 39 anos, com predomínio do sexo masculino (64,3%). Após regressão logística múltipla, apenas a variável transfusão sangüínea permaneceu como fator de risco para o HCV (OR=4,28; IC 95%: 1,44;12,73). CONCLUSÕES: A prevalência da co-infecção HIV/HCV foi baixa, a transfusão sangüínea foi um fator de risco e o genótipo 1b do HCV foi o mais freqüente.

Household members and health care workers as supervisors of tuberculosis treatment

OBJECTIVE: To compare tuberculosis cure rates among patients supervised by household members or health care workers. METHODS: Prospective cohort study of 171 patients treated by the program in Vitoria, Southeastern Brazil, from 2004 to 2007. Each patient was followed-up for six months until the end of the treatment. Of the patients studied, a household member supervised 59 patients and healthcare workers supervised 112 patients. Patients' sociodemographic and clinic data were analyzed. Differences between groups were assessed using chi-square test or Student's t-test. Significance level was set at 5%. RESULTS: Most patients had smear positive, culture confirmed pulmonary tuberculosis. Two patients were HIV-positive. There were more illiterate patients in the healthcare-supervised group, in comparison to those supervised by their families (p=0.01). All patients supervised by a household member were cured compared to 90% of the patients supervised by health care workers (p = 0.024). CONCLUSIONS: Successful tuberculosis treatment was more frequent when supervised by household members.
