    Full Text Available Introduction Schistosomiasis is endemic in 74 countries and is considered a serious public health problem in some locations. Methods A transverse study was performed of 13 landless settlements in southern Sergipe from February to December 2009. The study included 822 settlers, of whom 601 underwent stool testing. Results The prevalence of schistosomiasis in landless workers was 4.3%. The population has a low education level, and basic sanitation services are not available to all residents. Conclusions The prevalence of schistosomiasis was low in the population and among different settlements, possibly because of different forms of water use by the settlers.

    2005-01-01

    Full Text Available Based on fieldwork carried out in Southern Brazil, this article analyses the achievements, difficulties and contradictions of the MST’s alternative project. It identifies the organizational structure of the MST as a major factor explaining the success of the movement. It highlights that mobilization and pressure on the state have also been instrumental to land distribution and the development of its settlements. It thus looks at the strategy that the MST had adopted towards participation in institutional politics and its alliance with the Workers Party in Southern Brazil and argues that this strategy and alliance will most likely change because of President Lula’s cabinet composition and policy orientation.

  8. Educating Brazilian workers about AIDS.

    Science.gov (United States)

    1991-12-01

    This article contains a the script for a slide-tape presentation entitled Working Against AIDS, a presentation developed by the Brazil Family Planning Association (BEMFAM) which is designed to debunk common misconceptions about the disease. This audio-visual, which targets Brazilian workers, can be used during talks, seminars, and meetings. A discussion of the issues involved usually follows the presentation of Working Against AIDS. The presentation contains 30 illustrated slides (these are included in the article). The presentation begins by explaining that much of the information concerning AIDS is prejudicial and misleading. The next few slides point out some of the common misconceptions about AIDS, such as claims denying the existence of the disease, or suggestions that only homosexuals and prostitutes are at risk. The presentation then goes on to explain the ways in which the virus can and cannot be transmitted. Then it discusses how the virus destroys the body's natural defenses and explains the ensuing symptoms. Slides 14 and 15 point out that no cure yet exists for AIDS, making prevention essential. Slides 16-23 explain what actions are considered to be high risk and which ones do not entail risk. Noting that AIDS can be prevented, slide 24 says that the disease should not present an obstacle to spontaneous manifestations of human relations. The next slide explains that condoms should always be used when having sex with someone who could be infected with AIDS. Finally slides 26-30 demonstrate the proper way to use and dispose of a condom.

  9. Brazilian union actions for workers' health protection

    Rodolpho Repullo Junior

    Full Text Available CONTEXT: Many authors have emphasized the importance of worker strength through unionized organizations, in relation to the improvement of working procedures, and have reported on the decisiveness of labor movement actions in achieving modifications within the field of work and health. OBJECTIVE: To describe the ways in which Brazilian unions have tried to intervene in health-illness and work processes, identifying the existence of commonality in union actions in this field. TYPE OF STUDY: Qualitative study. SETTING: Postgraduate Program, Environmental Health Department, Faculdade de Saúde Pública, Universidade de São Paulo, São Paulo, Brazil. METHODS: Union health advisers and directors were interviewed. Documents relating to union action towards protecting workers' health were collected and analyzed. RESULTS: Unions articulate actions regarding workers' health of a technical and political nature that involve many aspects and high complexity. These have been divided into thematic categories for better analysis. DISCUSSION: Union actions regarding workers' health in Brazil are restricted to some unions, located mainly in the southern, southeastern and northeastern regions of the country. Nonetheless, the unions undertaking such actions represent many professions of great economic and political importance. CONCLUSIONS: The recent changes in health and safety at work regulations, recognition of professional diseases, creation of workers' health services and programs within the unified health system, and operational improvements in companies' specialized safety and occupational medicine services, all basically result from union action. There is commonality of union action in this field in its seeking of technical and political strengthening for all workers and their general and local representation. This has the objective of benefiting collective bargaining between employers and workers. Inter-institutional action on behalf of workers' rights

  10. Population pressure, mechanization, and landlessness in Central Thailand.

    Science.gov (United States)

    Ramsay, A

    1985-04-01

    This paper evaluates 2 explanations of the growing landlessness noted in contemporary Thailand. The 1st conceptualizes landlessness as a natural consequence of population pressures on limited agricultural land, while the 2nd blames technologic changes that give larger farmers substantial advantages over smaller ones. The validity of the 2 explanations is tested by examining differing levels of landlessness among provinces in Thailand's Central Plain. Overall, 14% of farm households in the Central Plain area were landless in 1974-75; however, the range extended from 4% in Kanchanaburi to 38% in Ayuthaya province. Multiple regression analysis suggests a strong association betweeen the percentage of landless agricultural worker families among farm households in the Central Plain and new technology. It is hypothesized that it is not that technology causes landlessness, but that it creates a demand for agricultural labor. As more and more arable land in Thailand becomes occupied, it becomes increasingly difficult for farmers to open new land. Thus, many choose to become an agricultural laborer or to leave agriculture altogether. The commercialization of rice agriculture made it possible to find wage labor in the villages of the Central Plain in the 1930s and played a role in the creation of a landless labor class. Demand factors appear to be of importance in determining which provinces have the highest concentrations of farm workers, but the closing frontier hypothesis seems to explain the origins of landless agricultural workers in Central Plain provinces. A closing frontier is significantly associated with outmigration. Provinces with the least idle land are closest to having a closed frontier.

    living on settlements or in camps were that the Brazilian Health System had not been meeting their health needs, mainly due to access difficulties. For this group, their needs are met only after making complaints to and putting pressure on governors. CONCLUSIONS: The view held by families from the Landless Rural Workers' Movement was that the fact that they belonged to the Movement and were better organized meant their health was better than that of temporary rural workers. The conservative modernization of rural Brazil has led to worse conditions for temporary rural workers, while Agrarian Reform has allowed for a better quality of life and improved health conditions among families, when compared in the areas under study.

    2014-07-01

    Full Text Available Introduction Researchers studying the hearing health of forestry workers have revealed the presence of a noise-induced hearing loss (NIHL in this population and have concluded that the vibration of the equipment, the carbon monoxide released by motors, and pesticides might also contribute to NIHL. Objective To analyze the noise exposure in the Brazilian forestry industry workers and the effects on hearing. Methods The study sample comprised 109 employees of a company that specialized in reforestation. Their participants' mean age was 35.5 years (21 to 54 years, mean tenure at the company was 3.9 years (1 to 13 years, and mean total duration of noise exposure was 12.3 years (1 to 30 years. The existing documentation reporting on the jobs risk analysis was examined, noise level was measured, and pure tone audiometry was performed in all participants. Participants were divided into three groups according to their noise exposure levels in their current job. Results Of the participants who were exposed to noise levels less than 85 dBA (decibels with A-weighting filter, 23.8% had hearing loss, and 5.5% of the participants who were exposed to noise ranging from 85 to 89.9 dBA and 11% of the participants who were exposed to noise greater than 90 dBA had audiogram results suggestive of NIHL. Conclusion The implementation of a hearing loss prevention program tailored to forestry workers is needed.

    Full Text Available OBJECTIVE: To analyze the food intake of sugarcane workers' family members. METHODS: The food intake of 159 family members of sugarcane workers from Gameleira, Pernambuco, Brazilian Northeast, was investigated by directly weighing the foods on three non-consecutive days. The percent risk of inadequate macro- and micronutrient intakes was analyzed according to the Reference Dietary Intakes. The macronutrients were analyzed in relation to acceptable distribution intervals. The energy consumed from the various food groups was expressed as a ratio of the total energy intake. RESULTS: The median intake of carbohydrates and proteins remained above the Estimated Average Requirement, and all age groups presented a low risk of inadequate carbohydrate and protein intakes. The median intakes of riboflavin, niacin, thiamin, and iron remained above the Estimated Average Requirement for all age groups, but children aged 1-3 years presented a high percent risk of inadequate iron intake. All age groups presented high percent risk of inadequate zinc, calcium, vitamin A, and vitamin C intakes. Grains and derivatives had a greater participation in the total energy intake, especially in men aged 19-30 years. The group "milk and dairy products" had a greater participation in the diet of children aged 1-3 years. CONCLUSION: The low percent risk of inadequate carbohydrate and protein intakes in all age groups was opposed to the high risk of inadequate mineral and vitamin intakes, making the population vulnerable to nutritional disorders caused by excess macronutrient intake and inadequate micronutrient intake.

    Full Text Available Estudos sobre os multiletramentos têm chamado a atenção para a crescente importância de habilidades não-verbais no processo de aprendizagem e de construção de identidade, principalmente com o advento das novas tecnologias de comunicação. As habilidades, ou modos de produção de significado, mais importantes são cinco: visual, auditiva, gestual, espacial e multimodal. O objetivo deste trabalho é analisar o visual como modo de produção de significado e sua relação com o modo linguístico nas mídias do MST. Embora o movimento coloque grande ênfase no verbal, o trabalho com imagens pode ser visto também como fonte de empoderamento e construção de identidade do sem-terra.Studies on multiliteracies have been placing great emphasis on nonverbal skills in learning and in identity construction, especially with the rise of new technologies of communication. The most significant skills, or modes of meaning-making, are five: the visual, the audio, the spatial, the gestural and the multimodal. This paper aims at analysing the visual as a mode of meaning-making and its interaction with the linguistic mode in the MST's electronic and print media. Although the landless movement places great emphasis on the written-textual mode, it has been highly skilful in dealing with images in ways which contribute to the empowerment and identity construction of the landless.

    Full Text Available This paper aims to investigate the effects of investment in industrial R & D on the mobility of workers between firms and/or industrial sectors in Brazil, considering that the technological gap between the sectors can reduce the propensity for interindustrial labor mobility. Using panel data for the period 2003–2008, constructed from microdata RAIS-Migra and industry data from the Brazilian Technological Innovation Survey (PINTEC, the Annual Industrial Survey (PIA and input–output matrices, we estimate a multinomial logit model with random intercepts (GLLAMM – Generalized Linear Latent and Mixed Models. The main results show that the technological diffusion increases the chances of changing jobs, the technological variables have greater importance for unskilled workers than for skilled, and among non-intensive technology industries, the technological innovation can have positive impact on interindustrial mobility.

    Full Text Available This research has accomplished a critical appraisal on landlessness and economic development of Bangladesh through conducting a primary survey and traced out what are the best alternative recommendations to ameliorate land ownership pattern of the economy. Basically landlessness often materializes the manifestation of poverty, indebtedness and powerlessness of the majority of the rural households. The causes of landlessness and near landlessness are numerous including dearth of land, rapid population growth, low productivity in agriculture, lack of effective government policies, colonial legacies etc. Due to these circumstances, land-oriented poverty and rural to urban migration without any expansion in the housing and utility services lead to the expansion of slump with all affiliated social problems. On the other hand, it has been found that landlessness diminishes the rate of land-fragmentation, which facilitates automation in production process through both extensive and intensive directions. Therefore, this research has uncovered that landlessness has a significant level of positive impacts on economic development through facilitating modern technology in primary sector. For social welfare, the policymakers can rehabilitate the landless people through creating income generating activities. In this regard, setting up agro based industries as well as promoting employment in non agricultural sector is a must for achieving potential economic growth. However, this research also identified that landlessness causes to boom up the service sector. It has been happened due to the radical emergence of non-government organizations that generated income-oriented activities in the rural areas through social movement.

    Full Text Available Benzene is a ubiquitous environmental pollutant and an important industrial chemical present in both gasoline and motor vehicle emissions. Occupational human exposure to benzene occurs in the petrochemical and petroleum refining industries as well as in gas-station workers, where it can lead to benzene poisoning (BP, but the mechanisms of BP are not completely understood. In Brazil, a significant number of gas-station service workers are employed. The aim of the present study was to evaluate alterations related to BP and metabolic polymorphisms in gas-station service workers exposed to benzene in the city of Rio de Janeiro, Brazil. Occupational exposure was based on clinical findings related to BP, and metabolic polymorphisms in 114 Brazilian gas-station attendants. These workers were divided into No Clinical Findings (NCF and Clinical Findings (CF groups. Neutrophil and Mean Corpuscular Volume (MCV showed a significant difference between the two study groups, and neutrophil has the greatest impact on the alterations suggestive of BP. The clinical findings revealed higher frequencies of symptoms in the CF group, although not all members presented statistical significance. The frequencies of alleles related to risk were higher in the CF group for GSTM1, GSTT1, CYP2E1 7632T > A, but lower for NQO1 and CYP2E1 1053C > T genotypes. Moreover, an association was found between GSTM1 null and alterations related to BP, but we did not observe any effects of other polymorphisms. Variations in benzene metabolizing genes may modify benzene toxicity and should be taken into consideration during risk assessment evaluations.

    The objective of this study was to assess whether the Brazilian Workers’ Food Program (WFP) is associated with changes in the nutritional status of workers in the transformation industry. We conducted a cross-sectional, observational, comparative study, based on prospectively collected data from a combined stratified and two-stage probability sample of workers from 26 small and medium size companies, 13 adherent and 13 non-adherent to the WFP, in the food, mining and textile sectors. Study variables were body mass index (BMI), waist circumference (WC), and dietary intake at lunch obtained by 24-hour dietary recall. Data were analyzed with nested mixed effects linear regression with adjustment by subject variables. Sampling weights were applied in computing population parameters. The final sample consisted of 1069 workers, 541 from WFP-adherent and 528 from WFP non-adherent companies. The groups were different only in education level, income and in-house training. Workers in WFP-adherent companies have greater BMI (27.0 kg/m2 vs. 26.0 kg/m2, p = 0.002) and WC (87.9 cm vs. 86.5, p = 0.04), higher prevalence of excessive weight (62.6% vs. 55.5%, pintake of saturated fat (–1.34 g, psodium (–0.3 g, pintake of sodium and saturated fat—a positive finding. Therefore, the WFP needs to be revisited and its aims redefined according to the current epidemiological status of the target population of the program. PMID:28182763

    The present study reports the localization of acid phosphatase in the hypopharyngeal gland cells from workers (newly-emerged, nurse and forager), queens (newly-emerged and laying) and males (newly-emerged and mature for mating) of the Brazilian stingless bee, Scaptotrigona postica. The phosphatase activity varied in intensity and localization depending on the individual class, physiological age and the substrate used. In newly-emerged workers, the phosphatase-positive sites suggest the involvement of the enzyme with cellular differentiation that occurs in the presecretory phase, in nurse workers with protein synthesis and in forager workers with changes in cellular activity or glandular regression. In males mature for mating and laying queens, the positive sites are related to secretory activity, showing that the gland maintains some activity in spite of the regressive aspect. Of the substrates used, beta-glycerophosphate gave the least specific localization.

    2014-12-01

    Land use/land cover (LU/LC) changes have been reported to occur over large areas in Legal Amazon due to the introduction of large-scale mechanized agriculture, extensive cattle ranching and uncontrolled slash-and-burn cultivation since the 1980s. Around the same time, movements which poor peoples or landless peasants settle into abandoned land have been very active in Brazil. In many cases, these people lack agricultural experiences to yield sufficient production for livelihoods. Thus, it leads to abandon the land and repeat forest clearance. In recent year, education by NGOs to these people encourage spreading of agroforestry which is a land use management system in which trees are grown around or among crops or pasture land. In this study, we specifically aimed at clarifying changes in LULC and these biomass using ground observation data, remotely-sensed LANDSAT data and GIS techniques. We focus on four different settlements: old-established settlement (around 30 years), established settlement (around 20 years), productive settlement (7 year) and unproductive settlement (7 years). These four settelements were located at Santa Barbará province, about 40 km northeast from the center of Belém, the Pará state capital, in the northern part of Brazil. We clarify that the biomass change varied according to whether the settlement are productive or not.

    Full Text Available The evaluation of workers as potential reservoirs and disseminators of pathogenic bacteria has been described as a strategy for the prevention and control of healthcare-associated infections (HAIs. The aim of this study was to evaluate the presence of Enterobacteriaceae in the oral cavity of workers at an oncology hospital in the Midwest region of Brazil, as well as to characterize the phenotypic profile of the isolates. Saliva samples of 294 workers from the hospital’s healthcare and support teams were collected. Microbiological procedures were performed according to standard techniques. Among the participants, 55 (18.7% were colonized by Enterobacteriaceae in the oral cavity. A total of 64 bacteria were isolated, including potentially pathogenic species. The most prevalent species was Enterobacter gergoviae (17.2%. The highest rates of resistance were observed for β-lactams, and 48.4% of the isolates were considered multiresistant. Regarding the enterobacteria isolated, the production of ESBL and KPC was negative. Nevertheless, among the 43 isolates of the CESP group, 51.2% were considered AmpC β-lactamase producers by induction, and 48.8% were hyper-producing mutants. The significant prevalence of carriers of Enterobacteriaceae and the phenotypic profile of the isolates represents a concern, especially due to the multiresistance and production of AmpC β-lactamases.

    Full Text Available 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.OBJETIVO: No Brasil, desde 1992, inúmeras empresas comerciais e industriais vêm adotando programas de controle do uso de drogas de abuso no ambiente de trabalho.

    The inhalation of radon present in underground mines can imply in the deposition of its descendants in the lungs, which may cause harm to the lungs tissues and induce cancer. Concentrations of radon in the environment of underground mines above 1000 - 1500 Bq/m{sup 3} are internationally considered to require protective measures for the miners. The objectives of the present work were to determine the concentrations of radon in air, as well as the resulting doses due to the presence of this radionuclide in three underground mines of fluorite and three underground mines of coal in the State of Santa Catarina. The concentration of radon was measured employing two types of detectors of nuclear tracks (SSNTD), the LEXAN and the CR-39. This detection method consisted in counting, with the help of a microscope, tracks resulting from the interaction of alpha particles with the film, due to the penetration of Rn-222 in the interior of the detector chamber and its decaying process. The average dose to the workers of the coal mines was estimated as 0.7 mSv/a, value inferior to the limit of 1 mSv/a established by the Brazilian Nuclear Energy Commission (CNEN) for members of the public. On the other hand, the fluorite mines showed much higher concentrations of radon and superior to 1000 Bq/m{sup 3}. The inefficiency of the ventilation system and the liberation of radon during the various explosions may have contributed to the high concentrations of radon in these mines since the concentration of radium in the rocks (normal and weathered granites) and in the minerals (green and purple fluorides) that compose the mining environment are not high. The modification of the ventilation system of one of the fluorite mines was sufficient to reduce the radon concentration to levels of the order of 500 Bq/m{sup 3}. The weathered granite contributes more significantly to the increase of the concentration of Rn-222 in the air than the other rocks here studied, i.e. normal granite as well as

    Despite recent stability and socioeconomic development, Brazil's history is marked by social inequality, informality, precarious work, and psychosocial vulnerability, with little opportunity for decent and meaningful work, as recommended by the International Labour Office (ILO), for people in the country. Nevertheless, based on a social constructionist view, the hypothesis can be raised that there is no substantive definition of decent work, but rather a psychosocial one, constructed based on the discourse, narratives, and practices produced through the relational processes which grant sense and meaning to work. Therefore, the examination of narratives and discourses is an important methodological strategy to understand the socio-occupational reality of Brazil. Thus, this study aims to understand the senses attributed to working through content analysis of the narratives produced by a set of 20 urban workers and contrast them with the ILO definition of decent work, in an effort to analyze the relationships, similarities, and differences between an established collective social discourse and the interviewees' singular narratives. The main results point out that the participants look for working with fair wages, social protection, safety, and personal development opportunities, as the ILO recommends. The main difference is that these characteristics do not derive from the State's actions, as in the employment and formal qualification model, but come from informal sources, such as family and community relationship networks. The informal relationship networks produce job opportunities as well as social protection; qualification takes place through practical learning from more experienced colleagues; the opportunity to be able to keep working (employed or working informally) leads to success and safety; and the possibility to make choices and have control over one's life translates into personal and occupational development.

    Nepal suffers from massive poverty. The efforts of the Agricultural Development Bank (ADB) and the International Fund for Agricultural Development (AFAD) are directed to providing loans to small farmers for poverty alleviation. The 1st project between 1981 and 1987 and the 2nd project with closing loans in 1991 has assisted 88,000 rural poor in 41 districts, which is considerably more than the target of 58,000. A 3rd Loan Project funded just by ADB will benefit another 138,000 rural poor or 17% of eligible beneficiaries by 1995. Requirements for loans are income Rs2000, landless laborers, and farmers with .5 hectares of land. The credit limit is Rs30,000. An example of the improvement in standard of living of a mother and her 4 children is given; not only has her income increased form Rs2000/year to a potential Rs1800/month but her children are able to receive an education. She was 1 of 1550 participants in the subproject at Mahendra Nagar in the Dhanusa district. Another landless farmer joined an 8-person farmer group and the loan helped him establish a fishery which yields gross income of Rs7500/year. With an additional loan for expansion, he might be able to gross Rs15,000/year. The interest charge is 13% with repayment over 5 years compared with private moneylender charges of 60-100%. Support from the group organizer was needed, however, to encourage the fishery business, because the farmer's intentions were originally to buy a buffalo which other group members had done and then consumed, thus not providing for repayment of the loan. Organizers must not only direct farmers activities, but initially select suitable candidates, motivate them, and provide guidance. Organizers must have a certificate in science, social science, or agriculture. Loans can be obtained for agriculture, livestock and fish enterprises, cottage industries, and agricultural and retail trading. Group savings is encouraged through special meetings, as needed. 15% of the graduates have been

    This study aimed to analyze perceptions of conflict between workers and managers in primary healthcare units and to present a typology of conflicts on the job. This was a comprehensive interpretive case study with a critical hermeneutic approach. Data collection techniques included: focus group with managers, workplace observation, and worker interviews, conducted from April to November 2011. The results were triangulated and indicated the coexistence of distinct concepts of conflict, typified in six modalities: lack of collaboration at work; disrespect resulting from asymmetrical relations between workers; problematic employee behavior; personal problems; asymmetry with other management levels; and inadequate work infrastructure. The relevance of (non)mutual recognition, as proposed by Axel Honneth, stood out in the interpretation of the causes and practical implications of these conflicts.

    It is necessary to introduce the concept of media literacy when researching the relationship between the landless farmers and the media. Media literacy helps landless farmers gain more non-financial properties. Media can relieve and modulate landless farmers' perplexity in their status change. The media literacy level has a close connection with landless farmers' job opportunity and job quality. Governments and media organizations must work together to improve landless farmers' media cognitive ability, cultivate their capability of understanding as well as evaluating media, and improve their level of participating in media, so as to ensure their sustainable livelihoods.%考察失地农民与媒介的关系,则必须引入媒介素养的概念,较高的媒介素养有助于失地农民获取更多的非金融性资产;媒介可以缓解和调节失地农民在身份转型过程中产生的心理困惑;媒介素养水平与失地农民就业机会与质量有着密切的关系。政府、媒介组织必须形成合力,提升失地农民的媒介认知能力,培养失地农民理解与评价媒介的能力,提升失地农民参与媒介的水平,以解决其可持续生计问题。

  20. The Roles and Movements of Actors in the Deforestation of Brazilian Amazonia

    2008-06-01

    Full Text Available Containing the advance of deforestation in Brazilian Amazonia requires understanding the roles and movements of the actors involved. The importance of different actors varies widely among locations within the region, and also evolves at any particular site over the course of frontier establishment and consolidation. Landless migrants have significant roles in clearing the land they occupy and in motivating landholders to clear as a defense against invasion or expropriation. Colonists in official settlements and other small farmers also are responsible for substantial amounts of clearing, but ranchers constitute the largest component of the region's clearing. This group is most responsive to macroeconomic changes affecting such factors as commodity prices, and also receives substantial subsidies. Ulterior motives, such as land speculation and money laundering, also affect this group. Drug trafficking and money laundering represent strong forces in some areas and help spread deforestation where it would be unprofitable based only on the legitimate economy. Goldminers increase the population in distant areas and subsequently enter the ranks of other groups. Work as laborers or debt slaves provides an important entry to the region for poor migrants from northeast Brazil, providing cheap labor to large ranches and a large source of entrants to other groups, such as landless farmers and colonists. Capitalized farmers, including agribusiness for soy production, have tremendous impact in certain areas, such as Mato Grosso. This group responds to commodity markets and provides justification for major infrastructure projects. Landgrabbers, or grileiros, are important in entering public land and beginning the process of deforestation and transfer of land to subsequent groups of actors. These include sawmill owners and loggers, who play an important role in generating funds for clearing by other groups, ranging from landless migrants to large ranchers. They

    Full Text Available The space of work micropolitics in the Brazilian Family Health Strategy is a scenario where the protagonism of workers and users of health services takes place. The objective of this article was to recognize and study the diverse, creative, and dynamic potential of how the activities in the Brazilian Family Health Strategy are organized and, mainly, to see the other face of the health care technology: the health of the health workers. This is a qualiquantitative exploratory study, developed by the application of instruments for the evaluation of life quality and occupational history, supported by the observation and evaluation of the daily work in a Brazilian Family Health Strategy unit in the town of Jerônimo Monteiro, state of Espírito Santo, in Brazil. The results show that, when targeting his/her own health, the health worker is more concerned about health problems and disorders already installed, neglecting the preventive aspects. Signs of organic and psychic suffering were considered as caused by work overload and by precariousness of links and work conditions. The study also showed that reflections on occupational health in the Brazilian Family Health Strategy also need to be carried out and that health prevention and promotion need to be explored by health workers. It is also important to review the path of the Brazilian Family Health Strategy under the perspective of health workers, aiming at the construction of a humanized work environment.

O que se observou é que, no cotidiano, mulheres e homens, sujeitos históricos e culturais, apropriam-se desses discursos de gênero, ao mesmo tempo que buscam lidar com as contradições que se apresentam. Entre estas, colocam-se as diferentes jornadas de trabalho que, apoiadas em padrões relacionais fixos, determinam oito horas diárias para os homens na produção e quatro para as mulheres, em função do trabalho doméstico e do cuidado das crianças.This text presents a discussion on the division of labor in a collective settlement of the Landless Movement (Movimento dos Trabalhadores Rurais Sem Terra - MST in Santa Catarina, characterized by the collectivization of land and of all means of production. Within this form of organization and according to the directives established by the MST, an equalitarian and solidarious transformation of society, including the construction of new genre relations, is sought for. What has been noted, throughout the daily routine, is that men and women alike, both historical and cultural subjects, appropriate this discourse at the same time in which they try to deal with upcoming contradictions. Within the latter, and based on fixed relational standards, different work hours are thus established. Men are determined to work on a daily eight hour basis in production whereas women, due to domestic work and child rearing, are granted a four hour schedule.

    Full Text Available Commuting helps to keep balance between residence and workplace of workers. With growing accessibility and connectivity, the importance of commuting is increasing all over the world. It is becoming a major substitute to migration. In commute-studies, commute-pattern is an important chapter. It highlights commuters’ directions of movement, distance they cover, modes of transport they use, the time they take to commute, etc. Unlike the urban-based commute pattern, commute pattern in rural areas are relatively an under-researched issue. In fact, traditionally rural people are thought to carry a sedentary lifestyle. Using primary data, this study aims to explore the commute patterns of rural workers located in the village of Gandharbapur of Barddhaman district of West Bengal, India. All the commuters were found to be engaged in non-farm work. Commuters stem from two major groups. One group of commuters is accumulated farm-income induced. They possess sufficient agricultural land. Investing their surplus farm-income, they have established non-farm works. The second group of commuters is poverty-driven. They are landless poor or are marginal farmers and to escape poverty, they have slipped into these works. Located beyond the suburban area (Memari being the nearest town, most commuters commute to nearby rural areas. Due to non-availability of public transport, women commute less than men do. Regular-paid government employees commute longer than other workers commute. The article concludes with a summary of findings and recommendations for further research.

    Full Text Available O presente artigo analisa, desde a perspectiva de gênero, o tipo de inserção laboral da população de nível universitário nos últimos trinta anos no século XX. Para tanto, em um primeiro momento traça as mudanças mais amplas assistidas no mundo do trabalho neste período a partir de um diálogo com a literatura de referência. Em seguida, a partir da base de dados dos censos demográficos do Instituto Brasileiro de Geografia e Estatística de 1970 e 2000, compara distintos padrões e tendências de algumas variáveis relativas ao mercado de trabalho na população feminina e masculina. Esse enfoque discute em que medida as dinâmicas assistidas neste segmento também reproduzem uma divisão sexual do trabalho. Os principais resultados encontrados mostram que já nos anos 1970 a maioria das mulheres deste grupo trabalhava em tempo integral. Essa tendência se acentua nos trinta anos em questão, e nas demais variáveis observam-se tendências cada vez mais próximas às masculinas. No entanto, a permanência da segmentação ocupacional feminina e dos altos diferenciais salariais aponta para uma desconstrução ainda lenta dos constrangimentos que cercam a presença destas mulheres no mundo do trabalho.This article examines, from a gender perspective, the type of employability the population holding higher education degrees had over the last thirty years of the twentieth century. To achieve its goals, it first outlines the broader changes witnessed in the work market in this period based on a dialogue with the literature of reference. Then, based on the Brazilian Institute of Geography and Statistics' database of census figures of 1970 and 2000, it compares different patterns and trends of some variables regarding the labor market among men and women. This approach discusses the extent to which the dynamics seen in this segment also play out a gender division of labor. The main results show that already in the 1970s most women in this

    Full Text Available CONTEXTO E OBJETIVOS: Em um hospital universitário, entrevista direta de amostras estratificadas dos 3587 funcionários, visando determinar o nível de conhecimento e a conduta prática do corpo social diante do acidente vascular cerebral ou encefálico (AVE. Estabelecer prioridades para esforços educacionais. MÉTODO: Pré-teste para otimização do instrumento e cálculo amostrai. Entrevista de 309 funcionários sorteados. Inquérito consistindo em 32 questões sobre fisiopatologia, epidemiologia e mortalidade, clínica, fatores de risco, evolução e tratamento, comportamento pessoal diante da doença. Teste de Kruskal-Wallis para múltiplas comparações de dados não-paramétricos. RESULTADOS: O corpo social do hospital exibiu baixo nível de conhecimento teórico sobre o AVE e atitudes errôneas diante da doença. A performance dos enfermeiros foi superior à de auxiliares, técnicos e atendentes de enfermagem. O corpo de enfermagem, apesar de pontuar melhor na entrevista que a população leiga, mantém-se desinformado sobre as novas possibilidades terapêuticas e dissemina mitos sobre a doença. Entre os grupos profissionais leigos, o nível de educação formal não influenciou a performance na entrevista. CONCLUSÕES: A comunidade leiga e de saúde do HUCFF não reconhece adequadamente os sintomas típicos, a evolução provável dos pacientes e a necessidade de intervir rapidamente diante da doença cerebrovascular. O corpo de enfermagem não está preparado para a tarefa de difundir conceitos corretos sobre a doença. Somente programas específicos de educação continuada podem reverter este quadro, e devem ser considerados prioritários.BACKGROUND AND PURPOSE: This study was undertaken to evaluate professionals working at a university hospital as to their knowledge and attitudes towards stroke. METHODS: Individuals working in the hospital were divided in two groups, health care workers (HCW and non-health care workers (NHCW, and

    Full Text Available The Brazilian party system presents a paradox. Although the Workers Party (PT and the Brazilian Social Democratic Party (PSDB have controlled presidential elections for the last 20 years, their force at the other levels of electoral competition has not grown. The objective of this study is to undertake a discussion of this situation through the 2014 general elections. After attempting to explain why successive challengers have not been able to change the structure of competition for the Brazilian presidency, I will analyze the relation established between the pattern observed at this level and the other “connected” electoral disputes—both those for state executive and federal legislative office. The general conclusion is that even if the pattern continues, it is quite improbable that this will significantly impact the other levels of national political party competition.

    1991-04-01

    This work briefly describes Brazilian colonization of the Paraguayan agricultural frontier, analyzes factors responsible for expelling population from Brazil and for attracting Brazilians to Paraguay, and assesses the economic and social consequences of immigration to the area. Paraguay's vast and sparsely populated agricultural frontier in areas outside the Central subregion underwent a process of intense colonization from the early 1960s to the mid-1980s. The Paraguayan government initiated an ambitious colonization program in 1963 to increase production, relieve population pressure and subdivision of small parcels in the Central subregion, encourage agricultural modernization, and produce a more diversified agriculture. Paraguayan agriculture in the early 1960s suffered from excessive concentration of land in a few hands and resulting exclusion of around 3/4 of workers from ownership and from any possibility of obtaining credit to fund technological improvements. Results of studies 2 decades after implementation of the colonization plan suggest that it has failed in significant areas. Although a considerable population redistribution alleviated pressure in the Central subregion, it apparently resulted more from spontaneous movement of peasants outside the colonization areas than from the official program. Concentration of lands is now occurring in the colonization area. Assistance for agricultural modernization and diversification of production in the peasant sector has been minimal. On the other hand, production of soy, wheat, and cotton for export increased substantially, because of an entrepreneurial agriculture capitalized by foreign as well as national interests The unmet goals of the colonization program would have required structural reforms rather than simple spatial redistribution of the population. Many of the colonists in the 1970s were Brazilian families displaced by mechanized agriculture in the southern states of Parana, Santa Catarina, and Rio

    Full Text Available OBJECTIVE: To investigate factors associated with overweight and abdominal obesity in male and female workers. METHODS: This is a cross-sectional population-based study. A representative sample of 1,054 workers ranging from 18 to 74 years of age, selected among individuals covered by the Workers´ Food Program living in the Metropolitan region of Belém, Northern Brazil. Health-related behavior and anthropometry were assessed. Fasting blood samples were collected. RESULTS: Overweight prevalence was 38.0% among women and 50.4% among men. Among overweight subjects, there were 6.1% obese women and 10.7% obese men. Multivariate analysis was used to identify social behavior and clinical-biochemical factors associated with increased body adiposity (BMI > 25 kg/m² and increased waist circumference: > 80 cm for women and > 94 cm for men. Variables positively and significantly associated with overweight and abdominal obesity in men according to prevalence ratio (PR values were: age (1.02, high family income (1.05, smoking (1.36, hypertension (systolic blood pressure, 1.41; diastolic blood pressure, 1.85 and hypertriglyceridemia (2.29. In women, the PR of increased body adiposity was associated with: age (1.02, alcohol intake (1.42, hypertriglyceridemia (1.44, diastolic blood pressure (1.65 and hyperglycemia (1.71. CONCLUSIONS: The association of overweight and abdominal obesity with social behavior variables should be corrected with preventive and educational measures. Furthermore, association of overweight and abdominal obesity with clinical and biochemical variables places the urban workers from the Amazon region assisted by the Workers´ Food Program at a possible risk for morbidity and mortality from increased body adiposity.OBJETIVO: Investigar os fatores associados ao sobrepeso e a obesidade abdominal em trabalhadores de ambos os sexos.

    Full Text Available Prostitutes are vulnerable to unplanned pregnancies and abortions. In Brazil, abortion is a crime and there is no data about unsafe abortions for this population. The study describes how prostitutes perform illegal abortions and the health consequences thereof. Semi-structured interviews with 39 prostitutes from three cities in Brazil with previous induced abortion experience were conducted. Sixty-six abortions, with between one and eight occurrences per woman, were recorded. The majority of the cases resulted from sexual activity with clients. The inconsistent use of condoms with regular clients and the consumption of alcohol during work were indicated as the main causes of unplanned pregnancies. The main method to perform abortion was the intravaginal and oral use of misoprostol, acquired in pharmacies or on the black market. Invasive measures were less frequently reported, however with more serious health complications. The fear of complaint to the police meant that most women do not inform the health team regarding induced abortion. The majority of prostitutes aborted with the use of illegally-acquired misoprostol, ending abortion in a public hospital with infection and hemorrhagic complications. The data indicate the need for a public policy focusing on the reproductive health of prostitutes.

    The Brazilian Twin Registry (BTR) was established in 2013 and has impelled twin research in South America. The main aim of the initiative was to create a resource that would be accessible to the Brazilian scientific community as well as international researchers interested in the investigation of the contribution of genetic and environmental factors in the development of common diseases, phenotypes, and human behavior traits. The BTR is a joint effort between academic and governmental institutions from Brazil and Australia. The collaboration includes the Federal University of Minas Gerais (UFMG) in Brazil, the University of Sydney and University of Melbourne in Australia, the Australian Twin Registry, as well as the research foundations CNPq and CAPES in Brazil. The BTR is a member of the International Network of Twin Registries. Recruitment strategies used to register twins have been through participation in a longitudinal study investigating genetic and environmental factors for low back pain occurrence, and from a variety of sources including media campaigns and social networking. Currently, 291 twins are registered in the BTR, with data on demographics, zygosity, anthropometrics, and health history having been collected from 151 twins using a standardized self-reported questionnaire. Future BTR plans include the registration of thousands of Brazilian twins identified from different sources and collaborate nationally and internationally with other research groups interested on twin studies.

The objective of this study was to understand the perceptions of workers in institutions providing adolescent care, the difficulties they face and methods of overcoming them. The study was performed in São Carlos, Brazil. Data was collected at institutions providing adolescent care, by means of documents and performing interviews. The documents were analyzed based on the Bourdieu framework. Results showed that the institutions perceive adolescence and adolescents apart from their sociality and historicity and focus attention on problematic adolescents, and not as subjects with rights. A more radical change in these adolescents' view would enable the construction of new work process instruments capable of assisting them as a whole.

    The objective of this research was to analyze the organizational culture of a Brazilian public hospital. It is a descriptive study with quantitative approach of data, developed in a public hospital of São Paulo State, Brazil. The sample was composed by 52 nurses and 146 nursing technicians and auxiliaries. Data were collected from January to June 2011 using the Brazilian Instrument for Assessing Organizational Culture - IBACO. The analysis of the organizational values showed the existence of hierarchical rigidity and centralization of power within the institution, as well as individualism and competition, which hinders teamwork. The values concerning workers' well-being, satisfaction and motivation were not highly valued. In regard to organizational practices, the promotion of interpersonal relationship, continuous education, and rewarding practices were not valued either. It becomes apparent that traditional models of work organization support work practices and determine the organizational culture of the hospital.

    The objective of Brazilian Eratosthenes Project is the development and application of teaching training actions according the ``docent autonomy" concept to basic Astronomy Education. Argentina coordinates the project in South America, but Brazil works in this project since 2010 with the theme ``Projeto Eratóstenes Brasil" in the homepage: http://sites.google.com/site/projetoerato. Two schools measure a sticks shadow and communicate their results. After, they calculate an average radius of Earth. The stick (gnomon) should stay in vertical position in the leveled ground. Since 2010, the project received hundreds of Brazilian schools with different experiments that were constructed with autonomy, because our site doesn't show some itinerary pre-ready to elaborate the experiments. To collect data for our research, we will use interviews via Skype with the teachers. These data are useful to researches about Science Education area and the Teaching Formation. Teaching professional practice could change and we see modifications in the teachers work, what depends of their realities and context. This project intents to respect the docent autonomy. This autonomy to responsible modifications during continued formation is called ``activist formative model" according Langhi & Nardi (Educação em Astronomia: repensando a formação de professores. São Paulo: Escrituras Editora, 2012). This project discusses about researches in Astronomy Education - still extreme rare in Brazil, when we compare with other areas in Science Education. We believe that actions like this could motivate the students to learn more Astronomy. Furthermore, this national action can be a rich source of data to investigations about teaching formation and scientific divulgation.

    Full Text Available The study of the motivation of construction workers is limited to a relatively small body of knowledge. Although there is considerable research available regarding motivation and productivity, few researchers have provided a comprehensive analysis on the motivation of construction workers. The research stated that productivity in construction has not improved compared to other industry sectors such as manufacturing. This trend has been echoed in publications throughout the past five decades, and suggested that motivation is one of the key factors impacting productivity. This paper offers a comprehensive review of the published work that directly links the key words—construction and motivation. The findings have been presented in five themes, that is, motivation models, environment and culture, incentives and empowerment, and worker management. This paper concludes with two methods suggested by previous researchers to improve motivation of construction workers: (1 relevant worker incentives (intrinsic or extrinsic and (2 improved management practices, specifically regarding communication with workers.

    The process of urbanization has a broad and deep impact on farmers who live in the urban-rural area, and land acquisition is a necessary part of the process of urbanization. Therefore, it is necessary for us to study the farmers' land acquisition will and the factors that affect the will. As a metropolis of the middle region and the core city of the Wuhan City Circle, Wuhan plays an important role in boosting the development of the entire middle region as well as Wuhan City Circle. Therefore, we have selected Wuhan as the representative area of our research. The related data about land acquisition in this paper are obtained through structured interviews of 251 sample farmers who come from 28 villages in the urban-rural areas of Hongshan District, Jiangxia District, Xinzhou District, and Dongxihu District of Wuhan city and their lands have been expropriated in recent five years. The land acquisition will can be divided into the will of the overall land acquisition, the will of land acquisition proportion and the will of land acquisition purposes. In this paper, we analyzed the influencing factors of landless farmers' land acquisition will mainly using binary logistic regression model . The result indicates that the top five factors affecting farmers' land acquisition willingness are degree of dependence on arable land before land acquisition, satisfaction of the families' living conditions before land acquisition, the rationality of land acquisition compensation, the impact of land acquisition on the family economy and the impact of land acquisition on employment. The first two variables have negative impacts on the land acquisition will, while the other variables have positive impacts. In order to carry out land acquisition smoothly, the local government ought to further improve the standard of compensation for landless farmers, take a more reasonable compensation method and minimize the contamination or damage on the local rural environment as far as possible.

    Cause-specific mortality was evaluated among 2,666 men employed in the processing division of a rubber manufacturing plant. The division was divided into two sections: front processing (compounding, mixing and milling operations) and back processing (extrusion, calendering, cement mixing and rubberized fabrics operations). Mortality rates for all processing workers combined and for men in each section were compared with rates for U.S. White males or for workers employed in other divisions of the same plant. Compared with either referent group, men in the processing division had increased mortality from leukemia, emphysema, and cancers of the stomach, large intestine, and biliary passages and liver. An excess number of deaths from stomach and larger intestine cancer was found predominantly among men in the front processing section (33 observed vs. 17.7 expected deaths, based on rates in nonprocessing workers). Increased mortality from leukemia (14 observed vs. 7.3 expected) and from emphysema (22 observed vs. 11.0 expected) was present among men employed in the back processing section. Examination of mortality from these causes according to age and the year starting work, duration of employment, and years since starting work in the relevant sections of the processing division suggested that observed excesses of stomach cancer, large intestine cancer, leukemia, and emphysema among processing workers are related to occupational exposures. These results are consistent with the findings of studies of other groups of rubber workers.

    The urbanization of landless farmers is not just a shift of identity,but a complete change in lifestyle and state of life. The major problems exposed in the course of landless farmers′adaption and integration into the city include unstable economic income,inconsistent cultural values,weak psychological sense of identity as well as various interests conflicts between the farm-ers themselves.Investigation of community Z,the first landless farmers′community of Kunming city,shows that true integration into the city is decided and motivated by the farmers′internal demand,that is,whether they are willing to become urban dwell-ers.Urban landless farmers are flexibly practicing various habits in different fields according to their own interests.Meanwhile, they are constantly constructing their own social network as well as social capital.%失地农民在城市化适应的过程中,并非简单地只是身份的转变,更意味着是一种生活方式和生活状态的彻底改变。失地农民在城市适应和融入的过程中暴露出来的问题主要是:经济收入的不确定、文化价值观的不一致和心理认同感不强以及内部之间存在各种利益博弈。从昆明市第一个回迁房小区Z社区的村民来看,失地农民要真正融入城市,是一种内在式的需求,即是否要变成城市人,关键是在农民自身内在需求的驱动下而决定的。他们根据自身的利益,在各个场域灵活变通地实践着各种惯习,在不断建构着自身的社会网络的同时也在不断建构着自身的社会资本。

    1995-12-01

    The Department of Energy (DOE) is in the process of defining the magnitude and diversity of Decontamination and Decommissioning (D&D) obligations at its numerous sites. The DOE believes that existing technologies are inadequate to solve many challenging problems such as how to decontaminate structures and equipment cost effectively, what to do with materials and wastes generated, and how to adequately protect workers and the environment. Preliminary estimates show a tremendous need for effective use of resources over a relatively long period (over 30 years). Several technologies are being investigated which can potentially reduce D&D costs while providing appropriate protection to DOE workers. The DOE recognizes that traditional methods used by the EPA in hazardous waste site clean up activities are insufficient to provide the needed protection and worker productivity demanded by DOE D&D programs. As a consequence, new clothing and equipment which can adequately protect workers while providing increases in worker productivity are being sought for implementation at DOE sites. This project will result in the development of an Advanced Worker Protection System (AWPS). The AWPS will be built around a life support backpack that uses liquid air to provide cooling as well as breathing gas to the worker. The backpack will be combined with advanced protective garments, advanced liquid cooling garment, respirator, communications, and support equipment to provide improved worker protection, simplified system maintenance, and dramatically improve worker productivity through longer duration work cycles. Phase I of the project has resulted in a full scale prototype Advanced Worker Protection Ensemble (AWPE, everything the worker will wear), with sub-scale support equipment, suitable for integrated testing and preliminary evaluation. Phase II will culminate in a full scale, certified, pre-production AWPS and a site demonstration.

    Full Text Available This paper provides an evaluation of schooling inequality in Brazil using different indicators such as the Education Gini coefficient, the Education Standard Deviation and the Average number of Years of Schooling. We draw up a statistical description of Brazilian human capital dispersion in time over the last half century, across regions and states. Our analysis suggests several conclusions: 1 Strong reduction of educational inequalities measured by Education Gini index. 2 A three parts picture of Brazil seems to emerge, reflecting initial conditions. 3 High increase of the Average number of Years of Schooling. 4 A significant link between Education Gini and the average education length. 5 Education Standard Deviation leads to inverted results compared to Education Gini. 6 Brazilian data are consistent with an Education Kuznets curve if we consider Education Standard Deviation.Esse trababalho busca avaliar o grau de desigualdade educacional no Brasil baseado-se em diferentes indicatores tais como: o índice de Gini educacional, os anos médios de escolaridade e no desvio padrão educacional. Tenta-se colocar uma descrição estatistica da distribuição do capital humano no Brasil, incluindo as diferenças estaduais e regionais observadas durante a ultima metade do século. As conclusões da nossa análise são as seguintes: 1 Forte reduç ão das desigualdades educativas calculadas com o Gini educacional. 2 Um retrato tripartido do Brasil parece se formar refletindo as condições iniciais. 3 Um forte aumento dos níveis de escolarização. 4 Uma relação significativa entre o Gini educacional e os anos médios de estudos. 5 O desvio padrão educacional leva aos resultados inversos do Gini educacional. 6 Os dados brasileiros admitem uma curva de Kuznets educacional se considerarmos o desvio padrão educacional.

    The aim is to identify ergonomic intervention methods used for including people with disabilities (PD) in the Brazilian labor market, with emphasis on discussion of methods to analyze the fit between the worker and the workplace. Methods to evaluate the fit of the worker to the workplace identify the capabilities and limitations of PDs and the demands of work, combining these data, and comparing them, in order to obtain a detailed analysis of the fit were drawn from national and international publications. These show that the use of specific methods for PDs and others focused on the general population. Mutatis mutandis, there is a need for complementary tools to address this segment. Thus, for the Brazilian scenario, it is essential to develop specific methodological tools to assess the capabilities of a PD so that they may better interact with their job.

    Full Text Available Social insects have many defence mechanisms against pests and pathogens. One of these is hygienic behaviour, which has been studied in detail in the honey bee, Apis mellifera. Hygienic honey bee workers remove dead and diseased larvae and pupae from sealed brood cells, thereby reducing disease transfer within the colony. Stingless bees, Meliponini, also rear broods in sealed cells. We investigated hygienic behaviour in three species of Brazilian stingless bees (Melipona scutellaris, Scaptotrigona depilis, Tetragonisca angustula in response to freeze-killed brood. All three species had high mean levels of freeze-killed brood removal after 48 h ∼99% in M. scutellaris, 80% in S. depilis and 62% in T. angustula (N=8 colonies per species; three trials per colony. These levels are greater than in unselected honey bee populations, ∼46%. In S. depilis there was also considerable intercolony variation, ranging from 27% to 100% removal after 2 days. Interestingly, in the S. depilis colony with the slowest removal of freeze-killed brood, 15% of the adult bees emerging from their cells had shrivelled wings indicating a disease or disorder, which is as yet unidentified. Although the gross symptoms resembled the effects of deformed wing virus in the honey bee, this virus was not detected in the samples. When brood comb from the diseased colony was introduced to the other S. depilis colonies, there was a significant negative correlation between freeze-killed brood removal and the emergence of deformed worker bees (P=0.001, and a positive correlation with the cleaning out of brood cells (P=0.0008. This shows that the more hygienic colonies were detecting and removing unhealthy brood prior to adult emergence. Our results indicate that hygienic behaviour may play an important role in colony health in stingless bees. The low levels of disease normally seen in stingless bees may be because they have effective mechanisms of disease management, not because

    ABSTRACT OBJECTIVE To describe the translation and early stages of cross-cultural adaptation of the questionnaire Verwachtingen over werken (or “Return-to-work self-efficacy”) for workers in sick leave due to mental disorders, from the original in Dutch to the Brazilian Portuguese language. METHODS A panel gathering experts was formed to determine the questionnaire conceptual and item equivalence. For semantic equivalence, the Dutch-Portuguese Brazilian translations were consolidated and consensus meetings were held to structure versions of the instrument. Each version was back-translated from Brazilian Portuguese to Dutch and evaluated by one of the authors of the original version. The final version was submitted to two pre-tests for operational equivalence. RESULTS The original questionnaire in Dutch was translated twice to Brazilian Portuguese. During the process, four consensus meetings of the experts’ panel were performed to create the versions. Each version was back-translated to Dutch. One of the authors of the original questionnaire performed an evaluation on the first three versions until the definition of the final one, which was titled Expectativas sobre o trabalho (Expectations about work). Pre-tests’ participants did not reported problems to fill the questionnaire. CONCLUSIONS Results indicate that the Brazilian Portuguese cross-culturally adapted version maintains the original meaning of the questionnaire, while including characteristics peculiar to the Brazilian reality. Measurement and functional equivalence of this version must still be evaluated before its application can be recommended for workers who have been absent from work due to mental disorders.

    Until recently Oman was a country of emigration, but by 1980 an estimated 200,000 foreign workers were in the country due to the petroleum boom. Almost 1/3 of the estimated 300,000 Indian workers in the Gulf states were in Oman, a country whose colonial heritage was closely tied to that of India and many of whose inhabitants still speak Urdu. The number of work permits granted to Indians working in the private sector in Oman increased from 47,928 in 1976 to 80,787 in 1980. An estimated 110,000 Indians were working in Oman in 1982, the great majority in the construction and public works sector. A few hundred Indian women were employed by the government of Oman, as domestics, or in other capacities. No accurate data is available on the qualifications of Indian workers in Oman, but a 1979 survey suggested a relatively low illiteracy rate among them. 60-75% of Indians in Oman are from the state of Kerala, followed by workers from the Punjab and the southern states of Tamil Nadu and Andhra Pradesh and Bombay. Indian workers are recruited by specialized agencies or by friends or relatives already employed in Oman. Employers in Oman prefer to recruit through agencies because the preselection process minimizes hiring of workers unqualified for their posts. Officially, expenses of transportation, visas, and other needs are shared by the worker and the employer, but the demand for jobs is so strong that the workers are obliged to pay commissions which amount to considerable sums for stable and well paying jobs. Wages in Oman are however 2 to 5 times the level in India. Numerous abuses have been reported in recruitment practices and in failure of employers in Oman to pay the promised wages, but Indian workers have little recourse. At the same level of qualifications, Indians are paid less then non-Omani Arabs, who in turn receive less than Oman nationals. Indians who remain in Oman long enough nevertheless are able to support families at home and to accumulate considerable

    In this work, we study the behavior of Brazilian politicians and political parties with the help of clustering algorithms for signed social networks. For this purpose, we extract and analyze a collection of signed networks representing voting sessions of the lower house of Brazilian National Congress. We process all available voting data for the period between 2011 and 2016, by considering voting similarities between members of the Congress to define weighted signed links. The solutions obtained by solving Correlation Clustering (CC) problems are the basis for investigating deputies voting networks as well as questions about loyalty, leadership, coalitions, political crisis, and social phenomena such as mediation and polarization.

It is a cross-sectional descriptive study involving the target population of Community Health Workers and Psychosocial Care Center workers, linked to the Municipal Health Department of Pelotas in the Brazilian State of Rio Grande do Sul. The presence of common mental disorders was considered when the Self Report Questionnaire (SRQ was > 7 and the occurrence of depression when BDI > 12. In total, 257 professionals participated in the study. Among mental health professionals (n = 119, the prevalence of CMDs was 25.2% and depression was 23.5%, while the prevalence of CMDs was 48.6% and depression was 29% among CHA (n = 138. The ratio of CMDs between the two groups of professionals was statistically different (p < 0.001. In this study, it was observed that the CAPS professionals are more adapted to work issues, with less perceived health problems arising from work and with a lower prevalence of mental disorders compared to CHA.

The data regarding the three studied products, sawnwood of non-coniferous, veneer sheets and plywood, were joined through the method of Fisher so that an econometric evaluation of the market of the three products could be carried out. Supply and demand models of the Brazilian exports were specified. The results were satisfactory and they match with the literature. The supply of exports presented a positive answer in relation to the exporter's remuneration, to the production, to the use of the installed capacity (cycles of domestic economical activity and to the tendency, and negative in relation to the internal demand. The demand for the Brazilian exports was influenced positively by the world income, participation index and tendency, and negatively for the relative price. The low elasticity-price of the found demand can have implications in the conservation of the Brazilian forest resources because the exporters can increase the prices, reduce the amounts and still increase the incomes.

    OBJECTIVE To analyze lifestyle risk factors related to direct healthcare costs and the indirect costs due to sick leave among workers of an airline company in Brazil. METHODS In this longitudinal 12-month study of 2,201 employees of a Brazilian airline company, the costs of sick leave and healthcare were the primary outcomes of interest. Information on the independent variables, such as gender, age, educational level, type of work, stress, and lifestyle-related factors (body mass index, physical activity, and smoking), was collected using a questionnaire on enrolment in the study. Data on sick leave days were available from the company register, and data on healthcare costs were obtained from insurance records. Multivariate linear regression analysis was used to investigate the association between direct and indirect healthcare costs with sociodemographic, work, and lifestyle-related factors. RESULTS Over the 12-month study period, the average direct healthcare expenditure per worker was US$505.00 and the average indirect cost because of sick leave was US$249.00 per worker. Direct costs were more than twice the indirect costs and both were higher in women. Body mass index was a determinant of direct costs and smoking was a determinant of indirect costs. CONCLUSIONS Obesity and smoking among workers in a Brazilian airline company were associated with increased health costs. Therefore, promoting a healthy diet, physical activity, and anti-tobacco campaigns are important targets for health promotion in this study population.

    Full Text Available Abstract Human contact with solid waste poses biological, chemical, and physical health risks for workers involved in waste collection, transportation, and storage. The potential risk to human health resulting from contact with health services waste or household waste still sparks considerable controversy. The aim of this study was to identify the context of scientific discussions on risk/infection from the hepatitis B and C viruses in workers that collect solid waste from health services or households. The search covered publications up to 2013 in Brazilian and international databases, and 11 articles were selected through a literature review. Of these, six conclude that there is an increased risk of infection in workers that collect household waste when compared to those unexposed to waste, three point to greater risk for workers that collect health services waste as compared to those that collect ordinary waste, and the other two found no difference between exposed and unexposed individuals.

    About one person in eight remains employed past 65, the average age for retirement in the U.S. These persons tend to be highly reliable. They can adapt and learn new technology, but may require extra time to do so. Older workers have particular needs in the workplace due to physiological changes that accompany aging. They may require more lighting, and they may have decreased mobility, physical strength, and dexterity. These factors often have no impact on their ability to accomplish job duties. This chapter underscores the significant contributions that older workers often provide, and also addresses retirement planning.

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

    Renata Borges

    2013-12-01

    Full Text Available 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.

  17. Brazilian Studies Then and Now

    Directory of Open Access Journals (Sweden)

    Anthony Pereira

    2012-09-01

    Full Text Available In 1912 the Brazilian diplomat and scholar Manuel de Oliveira Lima gave six lectures at Stanford University that encapsulated his views of what we now call Brazilian Studies. This article summarizes Oliveira Lima’s lectures. It then points out three aspects of Oliveira Lima’s worldview that are problematic from the perspective of the twenty-first century: his Eurocentrism; the unproblematic nature of the nation-state in his thinking; and his largely negative view of Brazil’s racial heritage. The third part of the essay analyzes three aspects of Oliveira Lima’s lectures that are still contemporary. These are the need to establish an adequate comparative context for the study of Brazil; the difficulty of justifying an academic discipline that revolves around the study of a single country; and the challenge of uniting disparate and specialized disciplines in order to appreciate Brazil’s complexity and trajectory in the modern world. In the conclusion, some guidelines for maintaining Brazilian Studies as a vibrant field are suggested.

    The objectives of this study were to describe the work done by Brazilian children and adolescents and compare the socioeconomic and health profile of those that worked (or were looking for work) versus non-working youngsters. Based on the 2008 Brazilian National Sample Household Survey (PNAD/2008), we selected children and adolescents 5 to 17 years of age, divided into two analytical categories: "workers" (working or looking for employment) and "non-workers". We calculated prevalence rates for the characteristics of their main work, as well as socioeconomic and health variables comparing the two categories. Poisson regression was used to estimate prevalence ratios, adjusted by health characteristics, with "non-workers" as the reference category. Compared to "non-workers", the "workers" category was associated with a higher proportion of boys; age 14 to 17 years; black or brown skin color; lower school attendance; and worse housing conditions. Child labor was associated with worse self-rated health; chronic backache; arthritis or rheumatism; and depression. Effective policies to support families need to be strengthened to effectively fight child labor.

    2011-06-01

    Brazil's national response to AIDS has been tied to the ability to mobilize resources from the World Bank, the World Health Organization, and a variety of donor agencies. The combination of favorable political economic opportunities and the bottom-up demands from civil society make Brazil a particularly interesting case. Despite the stabilization of the AIDS epidemic within the general Brazilian population, it continues to grow in pockets of poverty, especially among women and blacks. We use resource mobilization theories to examine the role of Afro-Brazilian religious organizations in reaching these marginalized populations. From December 2006 through November 2008, we conducted ethnographic research, including participant observation and oral histories with religious leaders (N = 18), officials from the National AIDS Program (N = 12), public health workers from Rio de Janeiro (N = 5), and non-governmental organization (NGO) activists who have worked with Afro-Brazilian religions (N = 5). The mobilization of resources from international donors, political opportunities (i.e., decentralization of the National AIDS Program), and cultural framings enabled local Afro-Brazilian religious groups to forge a national network. On the micro-level, in Rio de Janeiro, we observed how macro-level structures led to the proliferation of capacity-building and peer educator projects among these religious groups. We found that beyond funding assistance, the interrelation of religious ideologies, leadership, and networks linked to HIV can affect mobilization.

    Full Text Available BACKGROUND: Most of the available instruments aimed to assess risk exposure associated with work-related musculoskeletal disorders were originally developed in English, which makes their use difficult in countries such as Brazil. OBJECTIVE: To test the clinimetric properties of the Quick Exposure Check (QEC instrument previously adapted into Brazilian-Portuguese. METHOD: The original version of the QEC was translated and cross-culturally adapted into Brazilian-Portuguese and tested with 107 workers in two sectors of a textile factory. The internal consistency and construct validity were tested using only baseline values from the participants while reproducibility (reliability and agreement was evaluated in a test-retest design with a seven-day interval. RESULTS: The adapted version presented appropriate levels of internal consistency (Cronbach's α=0.76; moderate intra-observer reliability (ICCs ranging from 0.41 to 0.60; moderate to substantial inter-observer reliability (ICCs ranging between 0.62 and 0.86. The standard error of the measurement (SEM ranged from 8.3 to 11.2 points. Moderate levels of construct validity (Pearson's r=0.38 were observed. CONCLUSIONS: The Brazilian version of the QEC has appropriate clinimetric properties for measuring different levels of exposure to ergonomics risk factors and can now be used by Brazilian researchers and Occupational Health professionals.

    Nonreproductive workers of many eusocial Hymenoptera 'police' the colony, that is, they attack reproductive sister workers or destroy their eggs (unfertilized; developing into haploid males). Several ultimate causes of policing have been proposed, including (1) an increase in colony productivity......, applicable if reproductive workers work less, or (2) an increase in worker-to-male relatedness, applicable if within-colony relatedness is low. To explain the distribution of policing across taxa, the explanatory power of these and other potential ultimate causes should be assessed separately.

    Using a database that includes the universe of individuals and establishments in Denmark over the period 1991-2008 we analyze the effect of a large inflow of non-European (EU) immigrants on Danish workers. We first identify a sharp and sustained supply-driven increase in the inflow of non......-EU immigrants in Denmark, beginning in 1995 and driven by a sequence of international events such as the Bosnian, Somalian and Iraqi crises. We then look at the response of occupational complexity, job upgrading and downgrading, wage and employment of natives in the short and long run. We find...... that the increased supply of non-EU low skilled immigrants pushed native workers to pursue more complex occupations. This reallocation happened mainly through movement across firms.

    The new European chemicals legislation REACH (Registration, Evaluation, Authorisation and restriction of Chemicals) requires the development of Exposure Scenarios describing the conditions and risk management measures needed for the safe use of chemicals. Such Exposure Scenarios should integrate considerations of both human health and the environment. Specific aspects are relevant for worker exposure. Gathering information on the uses of the chemical is an important step in developing an Exposure Scenario. In-house information at manufacturers is an important source. Downstream users can contribute information through direct contact or through their associations. Relatively simple approaches (Tier 1 tools, such as the ECETOC Targeted Risk Assessment and the model EASE) can be used to develop broad Exposure Scenarios that cover many use situations. These approaches rely on the categorisation of just a few determinants, including only a small number of risk management measures. Such approaches have a limited discriminatory power and are rather conservative. When the hazard of the substance or the complexity of the exposure situation require a more in-depth approach, further development of the Exposure Scenarios with Tier 2 approaches is needed. Measured data sets of worker exposure are very valuable in a Tier 2 approach. Some downstream user associations have attempted to build Exposure Scenarios based on measured data sets. Generic Tier 2 tools for developing Exposure Scenarios do not exist yet. To enable efficient development of the worker exposure part of Exposure Scenarios a further development of Tier 1 and Tier 2 tools is needed. Special attention should be given to user friendliness and to the validity (boundaries) of the approaches. The development of standard worker exposure descriptions or full Exposure Scenarios by downstream user branches in cooperation with manufacturers and importers is recommended.

    Full Text Available Abstract Background Differences in sex hormone levels among populations might contribute to the variation in breast cancer incidence across countries. Previous studies have shown higher breast cancer incidence and mortality among Japanese Brazilians than among Japanese. To clarify the difference in hormone levels among populations, we compared postmenopausal endogenous sex hormone levels among Japanese living in Japan, Japanese Brazilians living in the state of São Paulo, and non-Japanese Brazilians living in the state of São Paulo. Methods A cross-sectional study was conducted using a control group of case-control studies in Nagano, Japan, and São Paulo, Brazil. Participants were postmenopausal women older than 55 years of age who provided blood samples. We measured estradiol, estrone, androstenedione, dehydroepiandrosterone sulfate (DHEAS, testosterone and free testosterone by radioimmunoassay; bioavailable estradiol by the ammonium sulfate precipitation method; and sex hormone-binding globulin (SHBG by immunoradiometric assay. A total of 363 women were included for the present analyses, comprising 185 Japanese, 44 Japanese Brazilians and 134 non-Japanese Brazilians. Results Japanese Brazilians had significantly higher levels of estradiol, bioavailable estradiol, estrone, testosterone and free testosterone levels, and lower SHBG levels, than Japanese. Japanese Brazilians also had significantly higher levels of bioavailable estradiol, estrone and DHEAS and lower levels of SHBG and androstenedione than non-Japanese Brazilians. Levels of estradiol, testosterone and free testosterone, however, did not differ between Japanese Brazilians and non-Japanese Brazilians. These differences were observed even after adjustment for known breast cancer risk factors. We also found an increase in estrogen and androgen levels with increasing body mass index, but no association for most of the other known risk factors. Conclusions We found higher levels of

    1. The workers' compensation system provides benefits to workers who are injured or made ill in the course of employment or their dependents regardless of fault. 2. The current workers' compensation laws benefit both the employer and the employee; however, workers' compensation is an exclusive remedy which bars recovery through a negligence lawsuit. 3. Workers' compensation regulations interact with other federal statutes such as the Americans With Disabilities Act and the Family Medical Leave Act. 4. Workers' compensation covers occupational injuries and occupational diseases, which may include cumulative trauma and mental stress claims. Nurses may be instrumental in evaluating and planning for an injured employee's return to work and occasionally in detecting fraudulent claims.

    Occupational health has always operated at the intersection of corporate economic concerns and worker health. Conflicting demands on the loyalty of occupational health professionals by the interests of labor and industry have made negotiating this minefield an essential part of the practice of occupational medicine. In recent years, occupational health professionals have found themselves increasingly required to rationalize worker health measures with economic arguments. This has led to physician engagement in the realm of defining and measuring worker productivity. Ethical guidelines that hold worker health as a top priority are critical in preserving the responsibility of occupational physicians to their patients.

The newspaper article was based on a special issue of Nature and on a new resource for scientometrics called Nature Index. I show here arguments and sources of bias that, under the light of the principle in dubio pro reo, it is questionable to dispute the quality and efficiency of the Brazilian science on these grounds, as it was commented on the referred article. A brief overview of Brazilian science is provided for readers to make their own judgment.

    During the past few decades, the Brazilian labor market has been characterized by an increase of unregistered workers, earning lower wages, not covered by social insurance or occupational risk prevention programs. This study describes the representations and perceptions about informal work contracts and job-related health risks, analyzed in a group of injured unregistered workers. This was a qualitative study based on in-depth interviews carried out with seventeen laborers, nine housemaids and eight construction workers. The findings indicate that workers recognize the importance of formal jobs, mainly because of legal guarantees of labor rights, mentioning the symbolic downgrading of informal jobs that undermines their self-esteem. Both work groups tended to minimize occupational health risks in the work environment, and did not recognize associations between informal job contracts and occupational accidents or diseases. It was clear that workers want to have job contracts. The findings of the study demonstrate the need for broader dissemination and discussion about labor rights and the construction of public policies that encompass health and safety programs for these workers.

    Perception and knowledge of the TB-infection risk in healthcare workers (HCWs) changed profoundly in Germany during the past few years. Molecular-epidemiological studies and a comprehensive review of the existing evidence concerning the infection risk for HCWs lead to the conclusion that TB in HCWs is often caused by infection at the workplace. In the Hamburg Fingerprint Study, 80 % of the TB cases in HCWs were caused by infections at the workplace. In a similar Dutch study 43 % of all cases were work-related. Besides of the well-known risks in TB wards and laboratories, an increased risk for infection should be assumed for paramedics, in emergency rooms, for HCWs caring for the elderly or for workers with close contact to high-risk groups (homeless people, i. v. drug users, migrants from high-incidence countries). TB in a HCW working in these fields can be recognised as an occupational disease (OD) without identifying a particular source of infection. For all other HCWs, the German occupational disease law requires the identification of a source case before TB in an HCW can be accepted as an OD. Even though the proportion of work-related TB in HCWs is higher than was assumed before previously, the prevalence of latent TB infection (LTBI) is lower than expected. In an ongoing evaluation study of the interferon-gamma release assay (IGRA) LTBI prevalence in HCWs is 10 %. Prevention strategies in Germany should be reconsidered in the light of these new findings.

    Through the survey of direct economic remuneration, indirect economic remuneration and non-economic remuneration of employees in flat panel furniture enterprises in Chengdu City, we conduct a comparative analysis of the problems and causes of remuneration difference between migrant workers and non-migrant workers. The results show that the wage difference between migrant workers and non-migrant workers is the biggest, and there is little difference in terms of interests safeguarding and non-economic factors. The reason for the above results lies in the difference of education level; gender, region, household registration and other issues have little impact on the above results. The following recommendations are put forward to improve the remuneration of migrant workers: increasing government’s policy advocacy efforts and eliminating subjective offense; establishing the administrative oversight bodies and effectively safeguarding the legitimate rights and interests of migrant workers; strengthening vocational training for migrant workers, so that workers have more choices on positions; improving the working environment and developing good working atmosphere.

    Full Text Available In recent years, the diffusion of mobile applications (mobile apps has risen significantly. Nowadays, mobile business apps are strongly emerging in business, enhancing productivity and employees’ satisfaction, whilst the usage of customized individual enterprise apps is still an exception. Standardized business apps enable basic functionalities, for example, mobile data storage and exchange (e.g., Dropbox, communication (e.g., Skype, and other routine processes, which support mobile workers. In addition, mobile apps can, for example, increase the flexibility of mobile workers by easing the access to firm’s information from outside the enterprise and by enabling ubiquitous collaboration. Hence, mobile apps can generate competitive advantages and can increase work efficiency on a broad scale. But mobile workers form no coherent group. Our research reveals, based on two case studies, that they can be clustered into two groups: knowledge workers and field workers. Knowledge workers and field workers fulfill different tasks and work in different environments. Hence, they have different requirements for mobile support. In this paper we conclude that standardized mobile business apps cannot meet the different requirements of various groups of mobile workers. Task- and firm-specific (individualized requirements determine the specification, implementation, and application of mobile apps.

    From 1993 to 2000, OSS worked under a cost share contract from the Department of Energy (DOE) to develop an Advanced Worker Protection System (AWPS). The AWPS is a protective ensemble that provides the user with both breathing air and cooling for a NIOSH-rated duration of two hours. The ensemble consists of a liquid air based backpack, a Liquid Cooling Garment (LCG), and an outer protective garment. The AWPS project was divided into two phases. During Phase 1, OSS developed and tested a full-scale prototype AWPS. The testing showed that workers using the AWPS could work twice as long as workers using a standard SCBA. The testing also provided performance data on the AWPS in different environments that was used during Phase 2 to optimize the design. During Phase 1, OSS also performed a life-cycle cost analysis on a representative clean up effort. The analysis indicated that the AWPS could save the DOE millions of dollars on D and D activities and improve the health and safety of their workers. During Phase 2, OSS worked to optimize the AWPS design to increase system reliability, to improve system performance and comfort, and to reduce the backpack weight and manufacturing costs. To support this design effort, OSS developed and tested several different generations of prototype units. Two separate successful evaluations of the ensemble were performed by the International Union of Operation Engineers (IUOE). The results of these evaluations were used to drive the design. During Phase 2, OSS also pursued certifying the AWPS with the applicable government agencies. The initial intent during Phase 2 was to finalize the design and then to certify the system. OSS and Scott Health and Safety Products teamed to optimize the AWPS design and then certify the system with the National Institute of Occupational Health and Safety (NIOSH). Unfortunately, technical and programmatic difficulties prevented us from obtaining NIOSH certification. Despite the inability of NIOSH to certify

    This work studies the Zipf Law for cities in Brazil. Data from censuses of 1970, 1980, 1991 and 2000 were used to select a sample containing only cities with 30,000 inhabitants or more. The results show that the population distribution in Brazilian cities does follow a power law similar to the ones found in other countries. Estimates of the power law exponent were found to be 2.22 +/- 0.34 for the 1970 and 1980 censuses, and 2.26 +/- 0.11 for censuses of 1991 and 2000. More accurate results were obtained with the maximum likelihood estimator, showing an exponent equal to 2.41 for 1970 and 2.36 for the other three years.

    This study aimed to develop and validate a Brazilian version of the Food Craving Inventory (FCI-Br), adapted to the cultural-gastronomic context of Brazil, and to explore this behavior among adult Brazilians. The Study 1 population consisted of 453 adults from all regions of Brazil. Participants responded to a preliminary form of the instrument online. Exploratory factor analysis revealed an FCI-Br presenting 23 items and three factors: High Fat, Sweet Food and Traditional Meal. The FCI-Br overall reliability was considered adequate (α = 0.82), as were each of the sub-scales. The food items receiving higher average scores from the application of the instrument were chocolate (3.14 ± 1.28; women) and bread (2.94 ± 1.44, men). A significant association was observed between the specific-craving for Sweet Food and female respondents. Most participants reported experiencing more frequent episodes of food craving when alone (68.0%; n = 391) and during the afternoon (32.2%; n = 127) or evening (43.8%; n = 173) hours. Application of the FCI-Br in a population of 649 university students (Study 2) demonstrated a good adjustment of the model developed according to the Confirmatory factor analysis (χ(2)/gl = 2.82, CFI = 0.94; TLI = 0.93; RMSEA = 0.06). The current findings indicate that the FCI-Br has adequate psychometric properties to measure craving behavior with respect to specific food groups in the resident population of Brazil. The results of this study also shed light on the importance of considering the cultural diversity of a population when investigating eating behaviors.

    Hand dermatitis is common in workers in the horticultural industry. This study determined the prevalence of hand dermatitis in workers of Alstroemeria cultivation, investigated how many workers had been sensitized by tulipalin A (the allergen in Alstroemeria) and took stock of a wide range of determinants of hand dermatitis. The 12-month period prevalence of major hand dermatitis amounted to 29.5% whereas 7.4% had minor dermatitis. Of these workers, 52.1% were sensitized for tulipalin A. Several personal and work-related determinants played a role in the multifactorial aetiology of hand dermatitis. Factors which showed a significant relationship with major hand dermatitis were: female sex, atopic dermatitis, chapped hands and the frequency of washing hands. It may be concluded that the Alstroemeria workers are a population at risk of developing contact dermatitis and it might be useful to carry out an educational campaign to lower the high prevalence.

  4. Futebol mulato: racial constructs in Brazilian football

    Directory of Open Access Journals (Sweden)

    Tiago Fernandes Maranhao

    2011-05-01

    Full Text Available The aim of this paper is to review Gilberto Freyre’s ideas about futebol mulato and the way these ideas have spread the notion of the Brazilian mulatto as a symbol of a ‘racial democracy’, unique in Brazil, around the world. The notion first appeared in 1938 in an article by Freyre for the Diários Associados, an important Brazilian newspaper. Football (soccer was employed by Freyre as the special arena where the multiracial Brazilian nation could shine and show the world a different way of being, opposed to the white and ‘rational’ way of European football. In Freyre’s work, the so-called ‘football-art’ was compared to poetry, while the European style was equated with prose. This essay argues that Freyre’s ideas were useful in constructing the Brazilian identity, a nation of harmony in all its aspects, including the area of race, and how the idea of the mulatto has been used to minimise social disparities within Brazilian society. Freyre’s ideas remain contemporary; many Brazilian intellectuals still refer to these concepts. As well, the press in this huge country, and especially in World Cup years, uses the concepts of mulatto and football-art to characterize Brazil and differentiate it from other countries.

    This study's objective was to revisit the internal consistency and convergent and discriminant factorial validity of the Brazilian version of WHOQOL-BREF, in a cross-sectional study of 386 health workers. Confirmatory factor analysis was used to test WHOQOL-BREF's structure (24 and 26 items) and the model suggested by exploratory factor analysis. Internal consistency was measured through composite reliability; convergent and discriminant validity by average variance extracted and factor correlations. The best-fit model, suggested by exploratory factor analysis (26 items), had 6 factors: 4 theoretically proposed (general, psychological, social relationships, and environment) and 2 obtained by subdividing the physical domain. Items "energy" and "security" (from physical and environment domains) were relocated to the psychological domain. Composite reliability was good (> 0.70), except for the general factor. Convergent and discriminant validity were adequate for social relationships and physical 2. Controversies on WHOQOL-BREF's dimensionality persist, particularly in the physical domain.

    Full Text Available OBJECTIVE: To assess the impact of multiple sclerosis (MS on the professional life of Brazilian patients. METHOD: One hundred MS patients were randomly selected from the database of the Brazilian Multiple Sclerosis Association (ABEM. An individual interview was carried out by telephone by a member of ABEM, who collected data on the patients' clinical status, educational level and professional lives. RESULTS: Complete data were obtained from 96 patients (27 males and 69 females aged 55.0±14.1 years, with average disease duration of 4.6±4.0 years. Eighty percent had eleven or more years of schooling. Among the whole group, 66% did not present limitations on walking. The longer the disease duration and the older the patient were, the higher the chances were that the patient was retired or receiving workers' compensation benefits. However, even among patients with MS for less than five years, the rate of non-participation in the workforce was 47.7%. Fatigue, paresthesia, cognitive dysfunction and pain were often cited as the motives for not working. CONCLUSION: MS patients presented high levels of unemployment, retirement and receipt of workers' compensation benefits, despite their high schooling levels. Age, disease duration and disability influenced these results for the whole group. However, even among younger patients with shorter disease duration and low disability, this finding remained.

    The Former Hanford Worker Medical Monitoring Program, directed by the Occupational and Environmental Medicine Program at the University of Washington, served former production and other non-construction workers who were potentially exposed to workplace hazards while working for the USDOE or its contractors at Hanford. The USDOE Former Workers Program arose from Congressional action in the Defense Authorization of 1993 (Public Law 102). Section 3162 stated that, “The Secretary shall establish and carry out a program for the identification and ongoing medical evaluation of current and former Department of Energy employees who are subject to significant health risks as a result of exposure of such employees to hazardous or radioactive substances during such employment.” (This also covers former employees of USDOE contractors and subcontractors.) The key objective has been to provide these former workers with medical evaluations in order to determine whether workers have experienced significant risk due to workplace exposure to hazards. Exposures to asbestos, beryllium, and noise can produce specific medical conditions: asbestosis, berylliosis, and noise-induced hearing loss (NIHL). Each of these conditions can be identified by specific, non-invasive screening tests, which are widely available. Treatments are also available for individuals affected by these conditions. This project involved two phases. Phase I involved a needs and risk assessment, characterizing the nature and extent of workplace health hazards which may have increased the risk for long-term health effects. We categorized jobs and tasks by likelihood of exposures to specific workplace health hazards; and located and established contact with former Hanford workers. Phase II involved implementation of medical monitoring programs for former workers whose individual work history indicated significant risk for adverse health effects. We identified 118,000 former workers, employed from 1943 to 1997

    Full Text Available A total of 2152 Actinobacteria strains were isolated from native Cerrado (Brazilian Savannah soils located in Passos, Luminárias, and Arcos municipalities (Minas Gerais State, Brazil. The soils were characterised for chemical and microbiological analysis. The microbial analysis led to the identification of nine genera (Streptomyces, Arthrobacter, Rhodococcus, Amycolatopsis, Microbacterium, Frankia, Leifsonia, Nakamurella, and Kitasatospora and 92 distinct species in both seasons studied (rainy and dry. The rainy season produced a high microbial population of all the aforementioned genera. The pH values of the soil samples from the Passos, Luminárias, and Arcos regions varied from 4.1 to 5.5. There were no significant differences in the concentrations of phosphorus, magnesium, and organic matter in the soils among the studied areas. Samples from the Arcos area contained large amounts of aluminium in the rainy season and both hydrogen and aluminium in the rainy and dry seasons. The Actinobacteria population seemed to be unaffected by the high levels of aluminium in the soil. Studies are being conducted to produce bioactive compounds from Actinobacteria fermentations on different substrates. The present data suggest that the number and diversity of Actinobacteria spp. in tropical soils represent a vast unexplored resource for the biotechnology of bioactives production.

    Full Text Available The permeability of Brazilian Eucalyptus grandis and Eucalyptus citriodora wood was measured in a custom build gas analysis chamber in order to determine which species could be successfully treated with preservatives. Liquid permeability was tested using an emulsion of Neen oil and a control of distillated water. Air was used to test the gas phase permeability. For both Eucalyptus grandis and Eucalyptus citriodora, the longitudinal permeability of gas was shown to be about twice as great as the liquid phase permeability. No radial permeability was observed for either wood. The permeability of air and water through the sapwood of Eucalyptus grandis was greater than that through the sapwood of Eucalyptus citriodora. The permeability of neen oil preservative through the sapwood of Eucalyptus grandis was also greater than through the sapwood of E. Citradora, but the difference was not statistically significant. Scanning Electron Microscopy images showed that the distribution and obstruction in the vessels could be correlated with observed permeability properties. Irrespective of the causes of differences in permeability between the species, the fluid phase flux through the sapwood of both species was significant, indicating that both Eucalyptus grandis and Eucalyptus citriodora could be successfully treated with wood preservative.

    In response to an alarming rise in human immunodeficiency virus (HIV) infection among Brazilian women during the early 1990s, the Sociedade Civil Bem-Estar Familiar no Brazil (BEMFAM) developed a project that integrates HIV prevention with clinical services, community-based prevention activities, and sexually transmitted disease diagnosis and treatment. Preliminary interviews with clinic clients revealed that women's fears they would be considered unfaithful were impeding their ability to suggest condom use to their sexual partners. Condom use within a relationship was considered appropriate only for pregnancy prevention. To facilitate dialogue about sexual health, BEMFAM developed a women's group intervention project. All women who attend a BEMFAM clinic are invited to participate in a one-hour group discussion before receiving medical services. Novela-style booklets with stories and characters women can relate to their own lives are used to stimulate discussion. Participants learn to use condoms correctly by putting them on a penis model and anticipate situations in which they would be able to negotiate condom use. The group setting enables women to gain confidence and practice assertiveness in a non-threatening, supportive environment. Their identification with other women's stories empowers women to take control of their health and sexual lives. Between October 1994 and July 1995, 3464 women participated in group discussions organized by BEMFAM and 40,688 condoms were distributed; 18% of these women returned to the clinic for additional condoms.

    Full Text Available We examined HIV frequency and probable risk factors among female sex workers in the port city of Imbituba, Southern Brazil. From December 2003 through February 2004, 90 female sex workers were interviewed in order to investigate demographic, socioeconomic and behavioral variables related to HIV infection. A blood sample of each woman was also collected to test for HIV antibodies. Six (6.7% of the sex workers were HIV-positive; the significantly-correlated risk factors were the daily number of clients (p = 0.008, the use of inhaled illicit drugs by the sex workers (P = 0.053 and by their clients (p = 0.005, and the lack of condom use in sexual relations (p = 0.015. The HIV infection rate in these sex workers was higher than that in the general population and similar to that found in other studies made with Brazilian populations presenting the same characteristics. This highlights the need for preventative measures, especially in this port area, in order to reduce transmission and to deter the introduction and dissemination of HIV.

  13. Interviewing media workers

    2010-11-01

    Full Text Available The focus of this article is on the use of Niklas Luhmann’s systems theoretical approach in order to analyse interviews conducted with media workers concerning their experiences of ethnic diversity in newsrooms. Applying systems theory means constructing the interview as a social system and seeing the “data” as observations produced by the observer and not as representations of a reality. The first part of the article describes the interview methodology and the second part provides examples, from the current study, of how systems theory can be applied in order to analyse interviews. Using a difference-theoretical approach means looking at the distinctions the informants make when talking about their experiences. These main guiding distinctions can be summarised as immigrant background/competence as well as advantage/competence. Using the guiding distinction of inclusion/exclusion when interpreting the interviewees’ statements, the interdependencies of mechanisms of inclusion and exclusion in newsrooms related to ethnic background can be examined.

    Full Text Available Reflecting on the importance of multiculturalism in teaching process and observing the otherness are primarily a challenge. This enables us to rethink what we have within ourselves, also to reconstitute memories involving discriminatory and unethical attitudes, which takes place in social fellowship. Based on the studies of Walsh (2007, 2009, Gomes (2007 and Tavares (2011, this work relies on decoloniality studies, mainly on the relevance of the history of Africa and Africanness in Brazilian education. Our corpus of analysis is found in the "Diretrizes Curriculares Nacionais para a Educação Básica" (DCN, 2013, the Brazilian Legislative Syllabus for Basic Education. Our focus is on the chapters concerning the Native-Brazilian and Quilomboa Education and ethnic-racial relations. Our most important aims are: to show the intercultural theoretical framework in which they are based on; to understand the immediate link established between the Native-Brazilian education and intercultural perspective; to clarify how the African diaspora was carried out in this particular case. Based on some Excel resources we were able to: 1 stablish the predominance of functional framework of interculturalism throughout these chapters, along with some critical features of interculturalism, as the issue of curricular decoloniality; 2 observe the established relationship between bilingualism and multiculturalism in the guidelines of Native-Brazilian education; and 3 identify a search for an effective inclusion of Africanness in curricula supported by the historical recognition and visibility of their sociocultural contribution.

    Ionizing radiation in Brazil is used in electricity generation, medicine, industry, agriculture and for research and development purposes. All these activities can generate radioactive waste. At this point, in Brazil, the use of nuclear energy and radioisotopes justifies the construction of a national repository for radioactive wastes of low and intermediate-level. According to Federal Law No. 10308, Brazilian National Commission for Nuclear Energy (CNEN) is responsible for designing and constructing the intermediate and final storages for radioactive wastes. Additionally, a restriction on the construction of Angra 3 is that the repository is under construction until its operation start, attaining some requirements of the Brazilian Environmental Regulator (IBAMA). The RBMN Project (Repository for Low and Intermediate-Level Radioactive Wastes) aims at the implantation of a National Repository for disposal of low and intermediate-level of radiation wastes. This Project has some aspects that are unique in the Brazilian context, especially referring to the time between its construction and the end of its institutional period. This time is about 360 years, when the area will be released for unrestricted uses. It means that the Repository must be safe and secure for more than three hundred years, which is longer than half of the whole of Brazilian history. This aspect is very new for the Brazilian people, bringing a new dimension to public acceptance. Another point is this will be the first repository in South America, bringing a real challenge for the continent. The current status of the Project is summarized. (author)

    Full Text Available NGOs came into the society in their present form after World War II and more precisely in 1960s. Before that also different forms of philanthropy existed. Like elsewhere in the world, in Pakistan also state and the market were the two sectors catering for different needs of the people. When foreign funding started coming into the poor countries, the channel of NGOs was considered more appropriate including the fact they had roots in the society and the benefit could reach the far flung areas. NGO field workers are the real actors in the NGOs’ activities but sadly the NGOs those raise the slogans of working for the destitute do not bother to facilitate the NGO field workers. Eventually the NGO field workers are facing problems of job insecurity, poor salary structure, unhealthy working environment and even harassment especially in case of women NGO field workers in Pakistan

    Concern about the increasing incidence of hand dermatitis in floral shop workers in the United States and its possible association to the plant Alstroemeria, a flower that has become popular since its introduction in 1981, prompted investigation of the prevalence and cause of hand dermatitis in a sample of floral workers. Fifty-seven floral workers were surveyed, and 15 (26%) reported hand dermatitis within the previous 12 months. Sixteen floral workers (eight with dermatitis) volunteered to be patch tested to the North American Contact Dermatitis Group Standard and Perfume Trays, a series of eight pesticides and 20 plant allergens. Of four of seven floral designers and arrangers who reported hand dermatitis, three reacted positively to patch tests to tuliposide A, the allergen in Alstroemeria. Patch test readings for all other plant extracts were negative. A positive reading for a test to one pesticide, difolatan (Captafol), was noted, the relevance of which is unknown.

  4. Domestic coalitions in the FTAA negotiations: the Brazilian case

    Directory of Open Access Journals (Sweden)

    Daniel Castelan

    2016-01-01

    Full Text Available Abstract This paper proposes an explanation to the domestic coalitions organised in Brazil around the FTAA negotiations, which stand as a hard case for the existing theories on political cleavages: industrialists and trade unions, albeit having shared common interests in the negotiations, did not adopt a joint strategy to foster their positions. The hypothesis to explain the political alignments in the FTAA is that the opening of the Brazilian market, which had advanced a lot in the years of negotiations, altered the priorities of workers and employers, as well as their preferences in foreign trade policy, hindering the reconciliation of class interests. Both agreed that the U.S. proposal for the FTAA was undesirable, but they completely disagreed on other issues that emerged in the political agenda during the reforms period, such as the role of the State in an open economy, the scope of labour and social rights and the social security system, the structure of taxation, etc. Some of the controversial issues were not new, but the international trade liberalisation intensified the dispute over them.

    2013-06-01

    Full Text Available This article discusses an analysis of public policies applied to education and their influence on economic development and social rise of workers in the Brazilian labor market, which requires efficient, economically productive people in constant training. It aims at examining the overall efficiency of the management model of educational public policies, as well as the teaching process and preparation of young people to the labor market. From the results of this study, we can conclude that there is a huge gap between institutions of secondary education and the labor market; we discussed questions such as how school refusal is caused by disinterest and lack of relationship between theory and practice, required for the insertion of the young in the labor market, as well as the lack of integration among schools, businesses and society. Thus, it is proved necessary to adopt more efficient policies to decrease the distance or lack of preparation of the young to develop the country's economic and bring social development.

    The author assesses the problem of illegal labor migration to Japan. "Labor policies, regulations, types of immigration violations, and the role of the recruitment industry are described. Most of the estimated 200,000 illegal workers are employed in small and medium sized enterprises, especially construction and manufacturing, which pay them wages well below the normal rate. A key issue is the infringement of human rights of these illegal workers, who lack the protection of labor laws and the social security system."

  9. Beyond Nationality: Dispatches from Immigrant Workers in the Global City

    Directory of Open Access Journals (Sweden)

    Manuel ABRANTES

    2012-05-01

    Full Text Available Research on migration policy, social structures and labour market dynamics underlines the persistent vulnerability of immigrants in the labour market of contemporary western societies. However, little attention has been paid to the diverse manners in which these factors overlap in the life of migrants moving within the same origin and destination settings. This article examines the case of Brazilian-born migrants working in Amsterdam, drawing on the analysis of statistical data, policy documents and fifteen life stories. It starts by explaining the aim of the research and the choice of origin and destination units. Findings are organized according to four key elements: legal status, gender, year of arrival, and occupation. It is argued that these elements comprise increasing differentiation mechanisms and provide an improved notion of what is at stake for migrant workers dwelling in the global city. The main conclusion is that international borders are undergoing a significant reorganization in their daily operation, in particular due to concomitant changes in migration law and flexibility strategies in the labour market. Reinforcement of distinct categories of migrants, expansion of rights for relatives or civil partners of European Union citizens and increasing pressure over undocumented workers require future research to consider whether migration policy is being replaced by a global order of human selection owing more to social and economic profile than nationality.

  10. Activities and Ergonomics of Workers in Broiler Hatcheries

    2015-06-01

    Full Text Available The objective this study was to assess ergonomic factors, posture and biomechanics of workers of a broiler egg hatchery. The analysis of ergonomic factors was based on physical work load, thermal environment, and exposure to light and noise. The posture of workers was analyzed using photographic records which were evaluated by the software program OWAS (Ovako Working Posture Analysing System. A biomechanics analysis was also performed based on the photographs taken of the employee at various angles, which were used as inputs to the Michigan two-dimensional biomechanical model software program. The results show that certain activities can be considered unhealthy due to the exposure of employees to physical and thermal overload. The continuous noise levels and lighting were outside the range considered adequate by the regulations of the Brazilian Ministry of Labor. The manner in which certain activities are carried out when associated with weight and poor posture can result in body lesions in broiler hatchery employees. It is therefore necessary to apply specific ergonomic programs, including scheduled breaks, training, and other measures in order to reduce or to eliminate the risks involved in these activities.

    Full Text Available This research note examines the results of the 2014 elections focusing on the National Congress. Its main objective is to ponder over common claims and predictions regarding the future of Brazilian politics. Beyond agreements and alliances involved in the electoral dispute, President Dilma Rousseff once again shall face the political challenges and dilemmas of Brazilian presidentialism, namely, how to create and manage government coalitions capable of implementing a coherent political program with a fragmented and heterogeneous Congress. The critical examination of the current hypotheses on the latest elections, especially concerning parliamentary fragmentation and a shift towards the right-wing, will serve as a compass attempting to formulate possible answers to such a fundamental problem in Brazilian politics.

    Full Text Available Huntington disease (HD is associated with expansions of a CAG trinucleotide repeat in the HD gene. Accurate measurement of a specific CAG repeat sequence in the HD gene in 92 Brazilian controls without HD, 44 Brazilian subjects with clinical findings suggestive of HD and 40 individuals from 6 putative HD families, showed a range from 7 to 33 repeats in normal subjects and 39 to 88 repeats in affected subjects. A trend between early age at onset of first symptoms and increasing number of repeats was seen. Major increase of repeat size through paternal inheritance than through maternal inheritance was observed. Data generated from this study may have significant implications for the etiology, knowledge of the incidence, diagnosis, prognosis, genetic counseling and treatment of HD Brazilian patients.

    Hydrolytic enzymes from hypopharyngeal gland extracts of newly emerged, nurse and foraging workers of two eusocial bees, Scaptotrigona postica, a native Brazilian stingless bee, and the Africanized honey bee (Apis mellifera) in Brazil, were compared. The hypopharyngeal gland is rich in enzymes in both species. Fifteen different enzymes were found in the extracts, with only a few quantitative differences between the species. Some of the enzymes present in the extracts may have intracellular functions, while others seem to be digestive enzymes. Scaptotrigona postica, had lower beta-glucosidase and higher lipase esterase activities than A. mellifera. The differences may be due to different feeding habits and behavioral peculiarities of the two species.

    The aim of this study was to examine the applicability of a Brazilian version of the Self-consciousness Scale to university students. Factorial structure, subscale intercorrelations, and normative data obtained with 182 subjects are reported. These results suggest that the proposed model of self-consciousness is applicable in the Brazilian culture, although some significant sex differences were found for two of the scales. Reliability tests and the factorial validity of the scale showed that this version still needs refinement to be used as a reliable research tool.

    Climate Change, Impacts and Vulnerabilities in Brazil: Preparing the Brazilian Northeast for the Future; Natal, Brazil, 27 May to 01 June 2012 The variability of the semiarid climate of the Brazilian northeast has enormous environmental and social implications. Because most of the population in this area depends on subsistence agriculture, periods of severe drought in the past have caused extreme poverty and subsequent migration to urban centers. From the ecological point of view, frequent and prolonged droughts can lead to the desertification of large areas. Understanding the causes of rainfall variability, in particular periods of severe drought, is crucial for accurate forecasting, mitigation, and adaptation in this important region of Brazil.

The objective of this study was to analyze the prevalence of musculoskeletal diseases and its difference among workers engaged in various jobs in the forestry. Two groups of workers were selected: woodcutters operating with chain-saw (N=33 and other loggers (N=32. Selected workers were of the similar age and had similar total length of employment as well as the length of service in the forestry. Both groups of workers employed in the forestry had the high prevalence of musculoskeletal diseases (woodcutters 69.7% and other loggers 62.5%, respectively. Degenerative diseases of spinal column were very frequent, in dependently of the type of activity in the forestry. Non-significantly higher risk of carpal tunnel syndrome was found in woodcutters with chain-saw compared to workers having other jobs in the forestry (OR=3.09; 95%CI=0.64-19.72. The lateral epicondylitis was found only in woodcutters operating with chain-saw with the prevalence of 18.2%.

    The prevalence of obesity, pre-diabetes, and type 2 diabetes (T2D) is increasing worldwide, especially in the developing nations of South America. Brazil has experienced an exponential increase in the prevalence of these chronic non-communicable diseases. The rising prevalence is probably due to changing eating patterns, sedentary living, and a progressive aging of the population. These trends and their underlying causes carry untoward consequences for all Brazilians and the future of Brazilian public health and the healthcare system. Lifestyle changes that include healthy eating (nutrition therapy) and regular physical activity (structured exercise) represent efficient inexpensive measures to prevent and/or treat the aforementioned disorders and are recommended for all afflicted patients. Regrettably, the implementation of lifestyle changes is fraught with clinical and personal challenges in real life. The transcultural Diabetes Nutrition Algorithm (tDNA) is a therapeutic tool intended to foster implementation of lifestyle recommendations and to improve disease-related outcomes in common clinical settings. It is evidence-based and amenable to cultural adaptation. The Brazilian Diabetes Association, Society of Cardiology and Ministry of Health guidelines for nutrition therapy and physical exercise were considered for the Brazilian adaptation. The resultant tDNA-Brazil and its underlying recommendations are presented and explained.

    Full Text Available ABSTRACT The present study aims to study earnings management in a significant sample of 123 banks in the Brazilian market between 2001 and 2012. Given the important role that banks play in a country's economy, it is important to understand that there are discretionary factors involved in the reporting of a financial institution's profitability. Credit provisioning guidelines for Brazilian financial institutions are described in Resolution 2682/99 of the National Monetary Council (Conselho Monetário Nacional. Because of the discretion allowed in this resolution, loan loss provision is used as instrument of earnings management, which is not an illegal practice, but this behavior does affect the risk perception of agents and analysts, and they should be aware of it and understand it. We found that credit provisioning is used as an earnings management mechanism to smooth the net income of Brazilian financial institutions. Brazilian banks tend to avoid not only negative net income pre-loan loss provisions and taxes, but also negative net income pre-loan loss provisions and taxes in relation to the previous period. Contrary to the previous studies, it is not clear if banks avoid lower net income pre-loan loss provisions and taxes than a given peer group.

    2001-01-01

    Full Text Available An analysis of Brazilian federal expenditures in science and technology is presented is this study. The 1990-1999 data were compiled from records provided by two federal agencies (MCT and CNPq responsible for managing most of the national budget related to these activities. The results indicate that the federal investments in Brazilian science and technology stagnated during the last decade (US$ 2.32 billion in 1990, US$ 2.39 billion in 1996, and US$ 2.36 billion in 1999. In contrast, a great increase in private investments in research was acknowledged both by industry and by the government during the same period, from US$ 2.12 to US$ 4.64 billion. However, this investment did not result in an increase in invention patents granted to residents (492 in 1990 and only 232 in 1997 or in a reduction of patent costs. Despite this unfavorable scenario, the number of graduate programs in the country has increased two-fold in the last decade and the contribution of Brazilians to the database of the Institute for Scientific Information has increased 4.7-fold from 1990 (2,725 scientific publications to 2000 (12,686 scientific publications. Unstable federal resources for science, together with the poor returns of private resources in terms of developing new technologies, may jeopardize the future of Brazilian technological development.

    Full Text Available The prevalence of obesity, pre-diabetes, and type 2 diabetes (T2D is increasing worldwide, especially in the developing nations of South America. Brazil has experienced an exponential increase in the prevalence of these chronic non-communicable diseases. The rising prevalence is probably due to changing eating patterns, sedentary living, and a progressive aging of the population. These trends and their underlying causes carry untoward consequences for all Brazilians and the future of Brazilian public health and the healthcare system. Lifestyle changes that include healthy eating (nutrition therapy and regular physical activity (structured exercise represent efficient inexpensive measures to prevent and/or treat the aforementioned disorders and are recommended for all afflicted patients.

    The aim of the study is to evaluate whether occupational exposure to night work could cause alterations in the levels of plasmatic cortisol. The interest toward this argument arises form several studies in scientific literature referring the presence of an alteration in the synthesis and release of cortisol in workers exposed to night work. We studied a population of workers employed in night security service and monitoring service of alarm systems in different museums compared to a control group not performing shift-work and/or night work. The exposed and control subjects were compared by age, length of service, smoking habit (n. cigarettes per day), habitual consumption of alcoholic drinks (n. glass of wine/beer per day). We evaluated the levels of plasmatic cortisol on 50 workers exposed to night work, all males of whom 30 smokers and 20 non-smokers and on 50 controls of whom 30 smokers and 20 non-smokers.

    Chest roentgenograms of 240 perlite workers employed for 1 to 23 years in the industry, showed no evidence of pneumoconiosis associated with perlite exposures. One individual, found to have simple pneumoconiosis, and one found to have complicated pneumoconiosis, had formerly been diatomaceous earth workers. Since only 28 of the men had been in the industry over 15 years and only seven for 20 years or more, continued surveillance is essential to make sure that there are no effects with more prolonged exposures. Studies of pulmonary function of the individuals who have had relatively long exposures are needed to supplement radiographic evidence.

    Full Text Available Timber harvesting activities are unquestionably related with high risk of work accidents and health disorders.Such activities were not only burdened the workers with heavy physical workloads due to uneasy workingenvironment, and massive work materials and tools, but also physiopsychologically burdened workers as theywere imposed with both mechanical and acoustic vibrations (noise produced by the chainsaw. However,  it is acommon practice that most of the workers still ignored the importance of the use of noise reduction devices suchas earmuff or ear plug.  This study was aimed to reveal the factual effects of noise on work concentration of theworkers to provide a scientific basis in supporting efforts in improving workers’ attitude.  The results confirmedthat chainsaw might produce noise during operation.  Noise intensities received by both right and left ears werenot significantly different, indicating that left-handed and normal workers received similar degree of noise inboth side of ears. Further, results also showed that there was a significant difference on the perception and workconcentration of chainsaw operators versus sedentary people to the noise.  These findings proved that hearingability of chainsaw operators had declined due to frequent noise exposure.Keywords: timber harvesting, physio-psychological disorder, noise, chainsaw

    Companies have increasingly sought strategies that will ensure a more competitive position in the marketplace. Among these strategies adopted by companies include the health and welfare of the worker, factors currently valued by consumers, especially those of most demanding market. Thus, the postural analysis is of great importance and interest because it is the study of positioning related to body parts like head, torso and limbs, capable of producing loads that may be excessive or insufficient causing disturbances in the muscle skeletal system worker. The aim of this study was to perform a postural analysis of the main sectors of workers (slaughter, cutting room, special cuts, packaging and dispatch) of a typical refrigerator pig industry in Brazil during the execution of their daily activities as well as developing proposals to minimize and/or eliminate the diseases and accidents. The study followed the safety norms of Brazilian Ministry of Labor and Employment. The posture analysis used the OWAS (Ovako Working Posture Analyzing System) methodology. The postures assumed by workers in the sector of packaging were as the most in need of emergency and quick action.

    This paper discusses the negative externalities associated with the intensive use of pesticides in the Brazilian savannah. These externalities are mainly related to impacts on the environment and on human health (rural workers and families, consumers), the costs of which end up being socialized. The externality considered in the present paper is of soil and water contamination by pesticides. The data source is the questionnaire of the Basic Municipal Information Research applied in 2003. Maps are used in order to associate contaminated areas with agricultural activity. Some risk factors associated with soil and water contamination by pesticides such as seasonal crop area, air pollution by burning and weed proliferation, were obtained through a logistic regression. The study concludes that the results can be helpful to formulate policies and aid in the design of regulating instruments and the definition of priority areas where preventive actions should be implemented.

    Pedro Lucas de Resende Melo

    2015-04-01

    Full Text Available The primary goal of this paper is to comprehend the fundamental organizational differences between Brazilian franchise chains that only operate in the home market and Brazilian franchise chains that operate internationally. The sample chosen for this study comprehends 96 Brazilian franchises operating in the home market and 67 franchises with international operations; logistic regression was used to analyze data obtained from these sources. Our findings suggest that the development of a brand in international operations can be strategic for certain Brazilian franchise chains; this seems to be, however, a scarce resource for many franchises and it could be developed through international operations. With regard to the fees charged, the outcomes demonstrate that Brazilian franchises with international operations tend to charge lower fees from its franchisees to install new units. Regarding the monitoring and control of franchises, there is evidence that the monitoring capability is one of the determining factors in the development of Brazilian franchises international operations.

    Full Text Available Agroforestry systems for animal husbandry in Brazil, including integrated crop-livestock-forest systems (ICLF, are very diverse, and present several technical, environmental and socio-economic benefits. For each of the country’s 5 regions (Southeast, Central-West, North, Northeast and South the prevailing agroforestry systems holding animals are presented, their potential and constraints discussed and research needs identified. In general, such systems are not broadly adopted, mainly because of their level of complexity compared with traditional systems, as well as some lack of understanding by farmers regarding their benefits. To change this situation, in the last 5 years, the Brazilian Government has allocated financial resources in terms of credit for development as well as for research and technology transfer addressing ICLF systems, including good agricultural practices and mitigation of greenhouse gas emissions. The goal is to improve competitiveness of the Brazilian agribusiness sector.

    Full Text Available We study the interaction between forward and spot electricity markets in a scenario where buyers and sellers are price takers in the forward market and trade through marketers, who play a Cournot game. Our model’s main features come from the Brazilian electricity market, where a free contract market coexists with a regulated contract market, and the spot price is the output of a stochastic dynamic algorithm. We are able to show that the price of energy bought (sold forward decreases (increases with the number of marketers, and that, as a result, full hedging is achieved in the limit. We also investigate the effects on prices of changes in the number of market participants and in aggregate consumption and supply, an exercise that yields important policy recommendations for the Brazilian regulator.

    Objective To estimate the prevalence of burnout in intensivist doctors working in adult, pediatric and neonatal intensive care units in five Brazilian capitals. Methods Descriptive epidemiological study with a random sample stratified by conglomerate with 180 intensivist doctors from five capitals representing the Brazilian geographic regions: Porto Alegre (RS), Sao Paulo (SP), Salvador (BA), Goiania (GO) and Belem (PA). A self-administered questionnaire examining sociodemographic data and the level of burnout was evaluated through the Maslach Burnout Inventory. Results A total of 180 doctors were evaluated, of which 54.4% were female. The average age was 39 ± 8.1 years, 63.4% had specialization as the highest degree, 55.7% had up to 10 years of work experience in an intensive care unit, and 46.1% had the title intensive care specialist. Most (50.3%) had weekly workloads between 49 and 72 hours, and the most frequent employee type was salaried. High levels of emotional exhaustion, depersonalization and inefficacy were found (50.6%, 26.1% and 15.0%, respectively). The prevalence of burnout was 61.7% when considering a high level in at least one dimension and 5% with a high level in three dimensions simultaneously. Conclusion A high prevalence of burnout syndrome among intensivist doctors was observed. Strategies for the promotion and protection of health in these workers must be discussed and implemented in hospitals. PMID:27737426

    Full Text Available Background : Automobile repair shop is a place where workers are exposed to harmful chemicals and toxic substances. Objective : To study the occurrence of obstructive and restrictive pulmonary impairment among automobile garage workers. Methods : A cross sectional study involving 151 automobile garage workers from 14 randomly selected garages of urban Kolkata. The study variables were Forced Expiratory Volume in 1 second (FEV 1 , Forced Vital Capacity (FVC, Peak Expiratory Flow Rate (PE FR, age, smoking habit, duration of work, type of work, and respiratory symptoms. The study was analysed using Regression equations, and Chi-square test. Results : All the workers were male. Obstructive impairment was seen in 25.83% of the workers whereas restrictive impairment was seen in 21.19% of the workers. Mixed obstructive and restrictive impairment was seen in 10.6% of the workers. The frequency of obstructive impairment was higher in older workers. In the age group of less than 20 years, 13.6% of the workers had obstructive impairment while 42.86% of workers above 40 years of age had obstructive impairment. Obstructive impairment was more frequently observed in battery repair workers (58.33% and spray painters (37.5% while 16.67% of the body repair workers and 30.19% of the engine mechanics had obstructive impairment. Obstructive impairment was more frequently observed in smokers (53.1 % as compared to ex-smokers (33.3% and non-smokers (6.4%. Obstructive impairment was more frequently observed in workers who had been working for a longer duration. Conclusion: Nearly 36.4% of the automobile garage workers had some form of pulmonary function impairment; obstructive and/or restrictive. The use of personal protective equipment, worker education, and discontinuation of the use of paints containing toxic pigments are recommended.

    Revisions to GDP announcements in many countries are often large, and Faust, Rogers, and Wright (2003) have found that G-7 GDP revisions are predictable to varying degrees. In this paper, we extend FRW to study revisions to Brazilian GDP announcements. We document that revisions to Brazilian GDP are large relative to those of G-7 countries. Brazilian GDP revisions are also predictable, which is consistent with the view that GDP revisions correct errors in preliminary GDP rather than reflect n...

    Full Text Available This study evaluated the indoor air quality in Brazilian universities by comparing thirty air-conditioned (AC (n = 15 and naturally ventilated (NV (n = 15 classrooms. The parameters of interest were indoor carbon dioxide (CO2, temperature, relative humidity (RH, wind speed, viable mold, and airborne dust levels. The NV rooms had larger concentration of mold than the AC rooms (1001.30 ± 125.16 and 367.00 ± 88.13 cfu/m3, respectively. The average indoor airborne dust concentration exceeded the Brazilian standards (<80 µg/m3 in both NV and AC classrooms. The levels of CO2 in the AC rooms were significantly different from the NV rooms (1433.62 ± 252.80 and 520.12 ± 37.25 ppm, respectively. The indoor air quality in Brazilian university classrooms affects the health of students. Therefore, indoor air pollution needs to be considered as an important public health problem.

    We have performed observations of the sky alongside with the Indians of all Brazilian regions that made it possible localize many indigenous constellations. Some of these constellations are the same as the other South American Indians and Australian aborigines constellations. The scientific community does not have much of this information, which may be lost in one or two generations. In this work, we present a planetary-observatory that we have made in the Park of Science Newton Freire-Maia of Paraná State, in order to popularize the astronomical knowledge of the Brazilian Indians. The planetary consists, essentially, of a sphere of six meters in diameter and a projection cylinder of indigenous constellations. In this planetary we can identify a lot of constellations that we have gotten from the Brazilian Indians; for instance, the four seasonal constellations: the Tapir (spring), the Old Man (summer), the Deer (autumn) and the Rhea (winter). A two-meter height wooden staff that is posted vertically on the horizontal ground similar to a Gnomon and stones aligned with the cardinal points and the soltices directions constitutes the observatory. A stone circle of ten meters in diameter surrounds the staff and the aligned stones. During the day we observe the Sun apparent motions and at night the indigenous constellations. Due to the great community interest in our work, we are designing an itinerant indigenous planetary-observatory to be used in other cities mainly by indigenous and primary schools teachers.

    Full Text Available Este artigo examina a evolução da reivindicação dos direitos da mulher à terra na reforma agrária brasileira sob o prisma dos três principais movimentos sociais rurais: o Movimento dos Trabalhadores Rurais Sem Terra (MST, os sindicatos rurais e o movimento autônomo de mulheres rurais. O mérito maior por levantar a questão dos direitos da mulher à terra é das mulheres dentro dos sindicatos rurais. Os direitos formais das mulheres à terra foram conseguidos na reforma constitucional de 1988, e em grande medida isso foi um subproduto do esforço para acabar com a discriminação contra as mulheres em todos as suas dimensões. A conquista das igualdades formais, contudo, não levou a um aumento na parcela de mulheres beneficiárias da reforma, a qual permaneceu baixa até a metade da década de 1990. Isso aconteceu principalmente porque garantir na prática os direitos da mulher à terra não estava entre as prioridades dos movimentos sociais rurais. Além disso, o principal movimento social a determinar o passo da reforma agrária, o (MST, considerava classe e gênero questões incompatíveis. Próximo ao final da década de 1990, entretanto, havia uma consciência crescente de que deixar de reconhecer os direitos da mulher à terra era prejudicial ao desenvolvimento e à consolidação dos assentamentos da reforma agrária e, portanto, para o movimento. O crescente consenso, entre todos os movimentos sociais rurais, sobre a importância em assegurar o direito da mulher à terra, junto com um lobby efetivo, encorajou o Estado em 2001 a adotar mecanismos específicos para a inclusão de mulheres na reforma agrária.This article examines the evolution of the demand for women's land rights in the Brazilian agrarian reform through the prism of the three main rural social movements: the landless movement, the rural unions and the autonomous rural women's movement.

    1997-07-01

    Cross-sectional questionnaire data were used to compare the levels of job strain in shift and daytime workers. Job strain was measured according to Karasek's Demands/Discretion model. Four occupational groups were included: drivers, industrial workers, policemen/watchmen, and cooks. The study subjects were a random sample of 508 daytime workers and 418 shift workers. Job demand did not differentiate between shift and daytime workers, comparing groups broken down by gender and by occupation. The daytime workers reported higher levels of job strain than the shift workers, and women experienced a higher level of job strain than did men. Multiple linear regression analysis showed that only occupational group and gender predicted job strain level. Shiftwork was not significantly associated with job strain in the regression model.

    Full Text Available In today’s global age many people cross national borders in search of better work and more wages. According to IOM, more than 100 000 000 workers leave their homeland and migrate to another country for this reason. Europe and North America have already experienced increase in foreign labor for many decades but nowadays, it is very common to see foreign laborers in Asian countries. As the number of foreign laborers rapidly increased, however, so did many social problems in relation to these workers. No country is safe from or immune to such social problems in regards to the foreign workers especially with a much easier and more efficient transportation system. In case of South Korea, the history of foreign labor may not be as long as other nations but as of 2007, it boasts of more than 250 000 foreign laborers and is thus facing just as many social problems as well. In order to investigate such social issues, this article explores the history of foreign laborers and their current situation in South Korea. Furthermore, this artticle examines both internal and external factors which may have caused exponential growth of foreign labor market in South Korea in the past decade.

    Construction workers are known to have occupational dermatoses. The prevalence of such dermatoses was unknown in Taiwanese construction workers. The objective of this study was to determine the work exposure, prevalence of skin manifestations, and sensitivity to common contact allergens in cement workers of southern Taiwan. A total of 1147 current regular cement workers were telephone-interviewed about skin problems during the past 12 months, work exposure, and personal protection. Among those interviewed, 166 were examined and patch tested with common contact allergens. A high % of cement workers reported skin problems in the past 12 months. More men (13.9%) reported skin problems possibly related to work than women (5.4%). Prevalence was associated with lower use of gloves, duration of work as cement worker, and more time in jobs involving direct manual handling of cement, especially tiling. A high % of dermatitis was noted in the 166 workers examined, which correlated with reported skin problems. On patch testing, construction workers had a high frequency of sensitivity to chromate. Sensitivity to chromate or cobalt was associated with reported skin problems, or dorsal hand dermatitis on examination. These workers' dermatitis was under-diagnosed and inadequately managed. It is concluded that cement workers in southern Taiwan had a high prevalence of skin problems related to cement use. Protective measures, work practice, and physician education should be improved to prevent or manage such problems.

    Objectives. This study examined absence rates among US Department of Energy workers who had beryllium sensitization (BeS) or were diagnosed with chronic beryllium disease (CBD) compared with those of other workers. Methods. We used the lymphocyte proliferation test to determine beryllium sensitivity. In addition, we applied multivariable logistic regression to compare absences from 2002 to 2011 between workers with BeS or CBD to those without, and survival analysis to compare time to first absence by beryllium sensitization status. Finally, we examined beryllium status by occupational group. Results. Fewer than 3% of the 19 305 workers were BeS, and workers with BeS or CBD had more total absences (odds ratio [OR] = 1.31; 95% confidence interval [CI] = 1.18, 1.46) and respiratory absences (OR = 1.51; 95% CI = 1.24, 1.84) than did other workers. Time to first absence for all causes and for respiratory conditions occurred earlier for workers with BeS or CBD than for other workers. Line operators and crafts personnel were at increased risk for BeS or CBD. Conclusions. Although not considered “diseased,” workers with BeS have higher absenteeism compared with nonsensitized workers. PMID:25211750

    Tooth loss continues to be a prevalent condition in Brazilian adults and elderly individuals. The aim of this cross-sectional study, conducted among workers in a wholesale grocery chain in the State of São Paulo, was to identify risk indicators for tooth loss in adults. The presence of caries and periodontal status were examined in 387 adults aged 20-64 years, according to World Health Organization criteria. Two outcomes were analyzed: loss of one or more teeth, and loss of four or more teeth. Independent variables analyzed were demographic and socioeconomic factors, clinical conditions, use of dental services, and self-perceived oral health. Poisson regression models were used for multivariate statistical analysis. Participants were missing a mean of 5.38 teeth, and 76.9% (n = 297) had lost at least one tooth; the most frequently lost teeth were permanent molars. Older age and the presence of visible dental biofilm were associated significantly with the two tooth loss outcomes (p adults.

    Full Text Available OBJECTIVE: The majority of cases of hepatocellular carcinoma have been reported in individuals with cirrhosis due to chronic viral hepatitis and alcoholism, but recently, the prevalence has become increasingly related to nonalcoholic steatohepatitis around the world. The study aimed to evaluate the clinical and histophatological characteristics of hepatocellular carcinoma in Brazilians' patients with nonalcoholic steatohepatitis at the present time. METHODS: Members of the Brazilian Society of Hepatology were invited to complete a survey regarding patients with hepatocellular carcinoma related to nonalcoholic steatohepatitis. Patients with a history of alcohol intake (>20 g/day and other liver diseases were excluded. Hepatocellular carcinoma diagnosis was performed by liver biopsy or imaging methods according to the American Association for the Study of Liver Diseases’ 2011 guidelines. RESULTS: The survey included 110 patients with a diagnosis of hepatocellular carcinoma and nonalcoholic fatty liver disease from nine hepatology units in six Brazilian states (Bahia, Minas Gerais, Rio de Janeiro, São Paulo, Paraná and Rio Grande do Sul. The mean age was 67±11 years old, and 65.5% were male. Obesity was observed in 52.7% of the cases; diabetes, in 73.6%; dyslipidemia, in 41.0%; arterial hypertension, in 60%; and metabolic syndrome, in 57.2%. Steatohepatitis without fibrosis was observed in 3.8% of cases; steatohepatitis with fibrosis (grades 1-3, in 27%; and cirrhosis, in 61.5%. Histological diagnosis of hepatocellular carcinoma was performed in 47.2% of the patients, with hepatocellular carcinoma without cirrhosis accounting for 7.7%.

    2015-01-01

    The aim of this study was to evaluate the adequacy of the Brazilian legislation about fluoride toothpaste. A search was conducted in LILACS, Medline and SciELO databases about the fluoride concentration found in Brazilians toothpastes, using descriptors on health. Publications since 1981 have shown that some Brazilian toothpastes are not able to maintain, during their expiration time, a minimum of 1,000 ppm F of soluble fluoride in the formulation. However, the Brazilian regulation (ANVISA, Resolution 79, August 28, 2000) only sets the maximum total fluoride (0.15%; 1,500 ppm F) that a toothpaste may contain but not the minimum concentration of soluble fluoride that it should contain to have anticaries potential, which according to systematic reviews should be 1,000 ppm F. Therefore, the Brazilian regulation on fluoride toothpastes needs to be revised to assure the efficacy of those products for caries control.

    Objective. This research was guided by a stress and support model to examine the effects of frontline workers' background characteristics, personal stressors, job-related stressors, and workplace support on satisfaction with supervision. Method. Survey data were collected from 644 workers in 49 long-term-care settings that employed them. Regression analysis were used to determine the effects of worker level and then Hierarchical Linear Modeling (HLM) and organizational factors on the outcome. Results. Although all four variable categories made significant contributions to explaining satisfaction with supervision, the most powerful were personal stressors and job-related stressors. Results from HLM analysis showed frontline workers in nursing homes and those employed in for-profit organizations had lower levels of satisfaction with supervision. Discussion. Findings suggest organizational interventions to address workers' financial and health issues and management practices such as better training programs and peer mentoring could enhance workers' satisfaction with supervision.

    2012-01-01

    Full Text Available While there have been a variety of studies concerning government worker motivation and productivity, few, if any, studies have focused specifically on state government workers’ perceptions about what factors affect their productivity. With more than 5 million workers employed by state governments in the United States, any improvement in state workplace productivity could have significant financial and service impact for society. In this study, state government workers identified those factors perceived as most affecting their workplace productivity. Data were collected through a survey offered to state government workers in the state of Wyoming. Factor analysis was used to derive key productivity factors from survey responses. The results indicate that state government workers appreciate having freedom and autonomy, like their jobs and the sense of achievement, and welcome teamwork, but feel limited by poor supervision and management, poor communications, and insufficient budgets and staffing. To improve productivity, the workers would eliminate bureaucracy, supervise better, and improve communication.

    Social parasites exploit the socially managed resources of their host's society. Inquiline social parasites are dependent on their host throughout their life cycle, and so many of the traits inherited from their free-living ancestor are removed by natural selection. One trait that is commonly lost...... is the worker caste, the functions of which are adequately fulfilled by host workers. The few inquiline parasites that have retained a worker caste are thought to be at a transitional stage in the evolution of social parasitism, and their worker castes are considered vestigial and non-adaptive.

    2013-06-01

    Brazilian keratin treatments are widely available products that are used by women all over the world to straighten hair. Marketers of these products claim that the keratin treatments render naturally curly hair more manageable and frizz-free while enhancing color and shine, giving the hair a healthier appearance. Although widely used, there have been virtually no reports of adverse side effects. Unfortunately, many of the products that are applied by salon professionals contain formaldehyde or its derivatives and are being marketed as safe.

    2009-09-01

    In Brazil most Construction and Demolition Waste (C&D waste) is not recycled. This situation is expected to change significantly, since new federal regulations oblige municipalities to create and implement sustainable C&D waste management plans which assign an important role to recycling activities. The recycling organizational network and its flows and components are fundamental to C&D waste recycling feasibility. Organizational networks, flows and components involve reverse logistics. The aim of this work is to introduce the concepts of reverse logistics and reverse distribution channel networks and to study the Brazilian C&D waste case.

  1. The Brazilian deindustrialization: financialization is not guilty

    2015-06-01

    Full Text Available The financialization of the Brazilian economy is often criticized as being responsible of the slowdown of capital accumulation in this country. Indeed, very high interest rates are maintained in order to finance the public debt, and this fosters capitalists to get more Treasury bonds rather than to invest in the productive area. Nevertheless, the evolution of the profit rate in this area also explains the particular relation existing between capitalists, finance and productive investment, as Marx showed it more than a century ago.

    Vibration hazards were surveyed in a population of quarry workers using chipping hammers and to a lesser extent, rock drills. Sixty-nine male quarry workers, aged 49.1 +/- 8.7 and exposed to vibration for 16.4 +/- 5.1 years, were surveyed in 1981-82. They were exposed to vibration for about 2-4 hours per days, mainly under a piece-work pay system. They had a high prevalence of Raynaud's phenomenon (36.2%) and numbness in upper extremities (53.6%). It is considered that the high prevalence was mainly due to large vibration levels in chipping hammers and rock drills and long daily exposure time. The attacks of Raynaud's phenomenon were found predominantly in the left hand, which held chisels, whereas the restriction of motion in the elbow was predominantly in the right arm which pushed chipping hammers. The same 49 male quarry workers in this population were also surveyed in 1976-77 and the prevalence of their complaints between 1976-77 and 1981-82 was compared. The prevalence of Raynaud's phenomenon was the same, but the frequency of the attacks increased between the two periods. The prevalence of other complaints such as numbness, pain and chills in the upper extremities also increased. Between 1976-77 and 1981-82, the prevalence of Raynaud's phenomenon, numbness, and pain in the upper extremities increased in the population of quarriers exposed to vibration for above 2.6 hours per day and 200 days per year, or 600 hours per year. On the other hand, the prevalence of these complaints mostly decreased in the population of quarriers with less exposure.

    Seipel, M M

    2000-01-01

    As a result of the recent implementation of work-oriented antipoverty programs, more welfare recipients can be expected to be working in low-wage jobs. With these jobs there is little hope that these workers' incomes will rise above the poverty level. One way to help support these low-wage workers is through tax reform. Although low-wage workers pay little or no federal tax, they still pay high payroll and local taxes. To help such workers keep more of their earnings, refundable taxes like earned income tax credit and child refund taxes should be expanded, and sales taxes on food should be eliminated.

    Full Text Available The increasing problems with multidrug resistance in relation to Corynebacterium, including C. diphtheriae, are examples of challenges confronting many countries. For this reason, Brazilian C. diphtheriae strains were evaluated by the E-Test for their susceptibility to nine antibacterial drugs used in therapy. Resistance (MIC < 0.002; 0.38 µg/ml to penicillin G was found in 14.8% of the strains tested. Although erythromycin (MIC90 0.75 µg/ml and azithromycin (MIC90 0.064 µg/ml were active against C. diphtheriae in this study, 4.2% of the strains showed decreased susceptibility (MIC 1.0 µg/ml to erythromycin. Multiple resistance profiles were determined by the disk diffusion method using 31 antibiotics. Most C. diphtheriae strains (95.74% showed resistance to mupirocin, aztreonam, ceftazidime, and/or oxacillin, ampicillin, penicillin, tetracycline, clindamycin, lincomycin, and erythromycin. This study presents the antimicrobial susceptibility profiles of Brazilian C. diphtheriae isolates. The data are of value to practitioners, and suggest that some concern exists regarding the use of penicillin.

    1998-06-01

    Beans are a major source of dietary protein in Brazil. However, high losses due to insect infestation occur after each harvest. To combat these losses, radiation processing of beans offers promise as an alternative to chemical treatment, provided the nutritional quality of beans is not impaired by the radiation treatment. Conflicting results have been published about the effect of radiation on the biological value of legume proteins. Therefore, two varieties of Brazilian beans were studied: 1) Phaseolus vulgaris L., var. carioca and 2) Vigna unguiculata (L.) Walp, var. macacar. The beans were irradiated with doses of 0, 0.5, 1.0, 2.5, 5.0 and 10 kGy. Since irradiated beans will be consumed after appropriate storage, the beans under study were stored for 6 months at ambient temperature. Protein quality was measured by a biological assay employing the nitrogen balance approach in weanling rats. The animals were fed with optimally cooked beans, which were the only source of protein ({approx}10%). Nitrogen contents of legumes, diets, animal urine and faeces were determined by Kjeldahl analysis. The indices for apparent protein quality: net protein utilisation, digestibility and biological value were not influenced by irradiation. Thus, radiation treatment of Brazilian beans offers considerable promise as an effective insect disinfestation process, without impairing the biological quality of the valuable bean protein.

    To assess the current practices in gout management among Brazilian rheumatology residents. We performed a cross-sectional online survey among all the rheumatology residents and those rheumatologists who had just completed their training (post-residency (PR)) regarding their approach to gout management. Results were compared with the 2012 American College of Rheumatology (ACR) gout guidelines and with the responses of a previous survey with a representative sample of practicing Brazilian rheumatologists (RHE). We received 224 responses (83%) from 271 subjects. Among all respondents, the first-choice treatment for gout flares was the combination of a nonsteroidal anti-inflammatory drug + colchicine for otherwise healthy patients. A target serum urate 75%. Less than 70% reported starting allopurinol at low doses (≤100 mg/day) for patients with normal renal function and <50% reported maintaining urate-lowering therapy indefinitely for patients without tophi. Among residents and PR, the residency stage was the main predictor of concordance with the ACR guidelines, with PR achieving the greatest rates. Reported practices were commonly concordant with the 2012 ACR gout guidelines, especially among PR. However, some important aspects of gout management need improvement. These results will guide the development of a physician education program to improve the management of gout patients in Brazil.

  15. The Brazilian education system. Students with disabilities

    Full Text Available The Brazilian education system provides a specific form of organization for the inclusive education of students with disabilities. Law No. 9394 dated December 20, 1996, “Lei de diretrizes e bases da educação nacional”, presents in Chapter V the “educação especial" as a form of organization offered to students "portadores de Necessidades especiais”. Admission of students with disabilities in the Brazilian schools was characterized by several phases: the welfarist phase, the integration phase and the inclusion phase, which is the most recent one and now being debated. The presence of a special device fosters the differences, even when everybody enters the classbecause a separation perspective damps down all the procedural and design efforts towards a true integration, holding back collaboration and action sharing among teachers. We consider however effective an action that accompanies the gradual learning evolution mediating between the student with disabilities and peers, between him and the teachers, between him and the learning tools designed.

    Full Text Available Leishmaniasis, an endemic parasitosis that leads to chronic cutaneous, mucocutaneous or visceral lesions, is part of those diseases, which still requires improved control tools. Propolis has shown activities against different bacteria, fungi, and parasites. In this study we investigated the effect of four ethanolic extracts of typified propolis collected in different Brazilian states, on Leishmania amazonensis performing assays with promastigote forms, extracellular amastigotes, and on infected peritoneal macrophages. Ethanolic extracts of all propolis samples (BRG, BRPG, BRP-1, and BRV were capable to reduce parasite load as monitored by the percentage of infected macrophages and the number of intracellular parasites. BRV sample called red propolis, collected in the state of Alagoas, and containing high concentration of prenylated and benzophenones compounds, was the most active extract against L. amazonensis. The anti-Leishmania effect of BRV sample was increased in a concentration and time dependent manner. BRV treatment proved to be non-toxic to macrophage cultures. Since BRV extract at the concentration of 25 µg/ml reduced the parasite load of macrophages while presented no direct toxic to promastigotes and extracellular amastigotes, it was suggested that constituents of propolis intensify the mechanism of macrophage activation leading to killing of L. amazonensis. Our results demonstrate, for the first time, that ethanolic extracts of Brazilian propolis reduce L. amazonensis infection in macrophages, and encourage further studies of this natural compound in animal models of leishmaniasis.

    Full Text Available This paper studies the determinants of international citations by Brazilian economists in papers published in the top domestic journals in 1994 and 2004. Brazilian research in economics has become more open to international influence and widespread geographically; researchers more specialized and technically oriented and the research topics more diversified. However, Brazil is plagued by editorial favoritism, reflected in the negative and significant impact of references to the works authored by domestic journals editors on international citations. We also find that longer technical papers written on topics other than the economic history of Brazil are more likely to cite foreign literature.Este artigo estuda os determinantes das citações internacionais dos economistas brasileiros em artigos publicados nas principais revistas domésticas de economia nos anos 1994 e 2004. A pesquisa de economia no Brasil se tornou mais aberta à influencia internacional e mais espalhada geograficamente; os pesquisadores mais especializados e tecnicamente orientados e os tópicos de pesquisa mais diversificados. Entretanto, a pesquisa continua sendo prejudicada pelo favoritismo editorial, refletido no impacto negativo e significante das referências dos autores aos trabalhos dos editores das revistas domésticas sobre as citacoes internacionais. Constatamos que artigos técnicos mais longos sobre tópicos que não sejam sobre história econômica do Brasil têm maior chance de citar a literatura internacional.

    2001-01-01

    Full Text Available Ochratoxin A is a nephrotoxic, teratogenic and imunotoxic compound produced by Aspergillus and Penicillium spp. It is a suspected carcinogen to humans and it is carcinogenic to rats. Recently it has drawn attention because it has been found in coffee and it has been the object of regulation by coffee importing countries. Brazil is the largest coffee producing country and its largest consumer. In order to conduct an initial assessment of the situation of the coffee produced in the country and offered to its population, one hundred and thirty two samples of Brazilian green coffee from 5 producing states (Minas Gerais, Paraná, São Paulo, Espírito Santo and Bahia and destined for the home market, were collected at sales points at the cities of Londrina and Santos, Brazil, and analyzed for ochratoxin A. The toxin was isolated in immunoaffinity columns and quantified by HPLC with florescence detection. The limit of detection was 0.7ng/g and the average RSD for duplicates of the samples was 11%. Twenty seven samples were found contaminated with the toxin and the average concentration for the contaminated samples was 7.1ng/g ochratoxin A. Neither the total number of defects nor the number of specific defects according to the Brazilian coffee classification system (black, partly -- black, sour, stinkers-black, stinkers-green, pod beans showed any relation to the contamination of the samples with ochratoxin A.

    2009-12-01

    Full Text Available Biodiversity is one of the most fundamental properties of Nature. It underpins the stability of ecosystems, provides vast bioresources for economic use, and has important cultural significance for many people. The Pampa biome, located in the southernmost state of Brazil, Rio Grande do Sul, illustrates the direct and indirect interdependence of humans and biodiversity. The Brazilian Pampa lies within the South Temperate Zone where grasslands scattered with shrubs and trees are the dominant vegetation. The soil, originating from sedimentary rocks, often has an extremely sandy texture that makes them fragile—highly prone to water and wind erosion. Human activities have converted or degraded many areas of this biome. In this review we discuss our state-of-the-art knowledge of the diversity and the major biological features of this regions and the cultural factors that have shaped it. Our aim is to contribute toward a better understanding of the current status of this special biome and to describe how the interaction between human activities and environment affects the region, highlighting the fragility of the Brazilian Pampa.

  20. Bidding Strategies in Brazilian Treasury Auctions

    2003-06-01

    Full Text Available Most empirical work in treasury auctions use aggregate auction results to examine bidding behavior. We investigate the strategies of bidders in Brazilian treasury auctions using both aggregate and bidder level data and find that more detailed information allows great improvements in the understanding of bidding behavior in treasury auctions. Classifying bidders according to characteristics regarding their institutional category and their nationality, we find evidence of distinct bidding behavior across types of bidders. Moreover, in line with previous evidence in auctions of Japanese government securities, we find that foreign bidders seem to obtain higher profits than those of national institutions. These results suggest that caution should be exercised in the interpretation of testes of bidding behavior that do not take differences in bidder’s characteristics into account and (or that assume that treasury securities are pure common-value goods. We find that Brazilian auctions are relatively illiquid as higher competition yields lower bidders’ discounts. Contrary to theoretical predictions of both common- and private-value auctions, we also find that bidders obtain lower profits in auctions with higher dispersion in bidders’ valuations.

    Full Text Available Brands may be perceived as possessing a set of distinct traits or characteristics, i.e., a personality, similar to aperson. Thus, the personality of a brand is relevant as a source of differentiation in an increasingly competitivemarket environment. In this study, the authors explore the dimensions of brand personality proposed by J. Aaker(1997, seeking to discover the particular evaluation dimensions of the Brazilian context. The study wasconducted in exploratory stages, beginning with a preparatory stage that was carried out by professionals andacademics from the fields of communication and marketing. This was followed by stages of conclusive researchusing an online survey with a sample of 1,302 Brazilian consumers. Two sub-samples were extracted: onecalibration sample for exploratory factor analysis and a validation sample to perform confirmatory factoranalysis in order to verify the convergent and discriminant validities of the final scale. Five dimensions of brandpersonality in Brazil were detected: credibility, joy, audacity, sophistication and sensitivity. These dimensionsshowed some differences in comparison with similar studies that had been carried out in other countries. Thestudy led to a scale of 28 items for measuring brand personality and made it possible to compare competingbrands in terms of brand personality.

    Jaime, P C; da Silva, A C F; Gentil, P C; Claro, R M; Monteiro, C A

    2013-11-01

    Obesity prevalence in the Brazilian adult population is 12.5% among men and 16.9% among women. Obesity control has been a subject of concern in Brazilian health policies since the publication of the National Food and Nutrition Policy in 1999. The initiatives include a comprehensive national intersectorial plan for obesity prevention and control focused on confronting its social and environmental causes, development of a food and nutrition education framework aimed at intersectorial public policies in the food and nutritional security field, promotion and provision of healthy food in school environments (linked to family farming), structuring nutrition actions in primary healthcare in the national healthcare system, promoting community physical activity, food regulation and control, and encouragement of public participation and food control. We conclude that several initiatives have been developed in Brazil to deal with the challenge of implementing an intergovernmental, intersectorial response to reverse the rising overweight and obesity rates. The success of this response will depend on a governance model that promotes joint and integrated action by different sectors and active participation of society to consolidate the actions, places and laws that protect health and promote healthy lifestyles.

    2003-04-01

    In this work, a comprehensive phylogenetic study based on 600 base pair nucleotide and on putative 200 amino acid sequences of NS5 was carried out in order to establish genetic relationships among 15 strains of 10 Brazilian flaviviruses: Bussuquara, Cacipacore, dengue type 1, 2 and 4, Iguape, Ilheus, Rocio, Saint Louis encephalitis (SLE), and yellow fever. Phylogenetic trees were created by neighbor-joining and maximum parsimony methods. These trees showed Brazilian flaviviruses grouped into three main branches: yellow fever branch, dengue branch subdivided in types 1, 2 and 4 branches, and Japanese encephalitis virus (JEV) complex branch including SLE virus strains, Cacipacore, Iguape, Rocio, Ilheus and Bussuquara. Viruses transmitted by Aedes mosquitoes, such as dengue and urban yellow fever, that are also the only Flavivirus causing hemorrhagic fevers in Brazil, were grouped in the same cluster. Encephalitis associated viruses, transmitted by Culex mosquitoes such as JEV complex branch including SLE virus strains, Cacipacore, Iguape, Rocio, Ilheus and Bussuquara were also grouped in the same clade.

The utilized data were obtained from the 5th European Working Conditions Survey, conducted in 2010 by the European Foundation for the Improvement of Living and Working Conditions. In light of these objectives, we collected a subsample of 284 health professionals, some of them from the International Standard Classification of Occupations—subgroup 22—(ISCO-08. The results indicated that the chance of a healthcare worker referring to him/herself as bullied increases among those who work on a shift schedule, perform monotonous and rotating tasks, suffer from work stress, enjoy little satisfaction from their working conditions, and do not perceive opportunities for promotions in their organizations. The present work summarizes an array of outcomes and proposes within the usual course of events that workplace bullying could be reduced if job demands were limited and job resources were increased. The implications of these findings could assist human resource managers in facilitating, to some extent, good social relationships among healthcare workers.

  7. Diasporic and Transnational Internationalization: The Case of Brazilian Martial Arts

    Full Text Available Brazilian diasporas overseas hasreceived little academic interest. Nevertheless, estimates suggest that around three million Brazilians currently live in other countries. The present study looks at a specific type of diaspora: small entrepreneurs from the Brazilian martial arts sector. The study adopts the case study method of research. The unit of analysis is comprised by the martial arts (capoeira and Brazilian jiu-jitsu. Data analysis used secondary and primary data from interviews. Cross-case analysis searched for similarities and differences in the internationalization processes of the two martial arts, using several analytical devices, such as chronologies, timelines, matrices, and pattern matching analysis. Evidences suggest that the concept of diasporic internationalization fits better capoeira than Brazilian jiu-jitsu. However, Brazilian jiu-jitsu shows an initial combination of diasporic and transnational characteristics, but more recently became fully transnational. Brazilian jiu-jitsu became a truly global business, formally organized and professionally managed. Capoeira, however, is still seen as non-commercial and as the preservation and practice of an ancient art. Such ethos, combined with the origin of its members in lower economic classes and their restricted access to capital turns internationalization into an often less profitable activity.

  8. Brazilian sandy beaches: characteristics, ecosystem services, impacts, knowledge and priorities

    Directory of Open Access Journals (Sweden)

    Antonia Cecília Zacagnini Amaral

    Full Text Available ABSTRACT Sandy beaches constitute a key ecosystem and provide socioeconomic goods and services, thereby playing an important role in the maintenance of human populations and in biodiversity conservation. Despite the ecological and social importance of these ecosytems, Brazilian sandy beaches are significantly impacted by human interference, chemical and organic pollution and tourism, as well as global climate change. These factors drive the need to better understand the environmental change and its consequences for biota. To promote the implementation of integrated studies to detect the effects of regional and global environmental change on beaches and on other benthic habitats of the Brazilian coast, Brazilian marine researchers have established The Coastal Benthic Habitats Monitoring Network (ReBentos. In order to provide input for sample planning by ReBentos, we have conducted an intensive review of the studies conducted on Brazilian beaches and summarized the current knowledge about this environment. In this paper, we present the results of this review and describe the physical, biological and socioeconomics features of Brazilian beaches. We have used these results, our personal experience and worldwide literature to identify research projects that should be prioritized in the assessment of regional and global change on Brazilian sandy beaches. We trust that this paper will provide insights for future studies and represent a significant step towards the conservation of Brazilian beaches and their biodiversity.

    Full Text Available http://dx.doi.org/10.5007/2175-7968.2013v1n31p119Jorge Amado (1912-2001 is the most translated Brazilian writer and the literary figure that has shaped the reception of Brazilian literature in the world.  He is credited with opening the international literary market to the post-dictatorship generation of Brazilian writers.  Yet Amado is also a controversial figure.  The debate around him is sparked by what some believe is sexual and ethnic stereotyping in his post-1958 works and the reinforcement of "paternalistic "racial views. His reception therefore is mixed. For his English-language readers, he is a fascinating source of exotic and titillating narratives about the vast, unknown country of Brazil, and for Brazilians he is either a "great ambassador of Brazilian culture around the world" or a faux populist who disguises sexist and racist attitudes behind charming prose. This paper will address Amado's literary career, his unique contributions to Brazilian letters, the challenges of translating his work, and his influence on the production of a new Brazilian literature for export

    Holanda, Wanessa Tenório Gonçalves; de Lima, Maria Luiza Carvalho; Figueiroa, José Natal

    2011-01-01

    The noise-induced hearing loss (NIHL) is a chronic and irreversible disease resulting of the exposure to noise in high levels at work. Even in the beginning, this hearing loss can damage in many degrees the worker's quality of life. Before this study, there wasn't an instrument, in Portuguese, to evaluate the psychosocial disadvantages of workers with NIHL. The aim of this research was to make a transcultural adaptation of an especific instrument to evaluate the hearing handicap from the original language to Portuguese, and check the reliability and legitimacy. The selected instrument passed by a process of semantic equivalence that was conducted in five stages: translation, back translation, critical appraisal of the versions, pre-test and a final review by a multi-professional group to develop a consensual version of the instrument for current use in Brazil. The instrument called "Inabilities Scale and Hearing Handicap" had, in general, acceptable psychometric measures, considering the little size of the sample and the fact that workers' hearing loss weren't too significant. Therefore, the Portuguese version of this instrument needs to be further tested in a representative sample of Brazilian workers with NIHL to ratify its utility in order to evaluate hearing handicap in this population.

  2. Brazilian vodkas have undetectable levels of ethyl carbamate

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available While in Europe vodka is mainly derived from potatoes or cereals, a large proportion of Brazilian vodka is likely obtained from sugarcane, which contains ethyl carbamate (EC precursors. EC, in addition to several other contaminants and congeners, were investigated in 32 samples of Brazilian vodka. All samples complied with the Brazilian regulations for congeners and contaminants, having EC content below 0.01 mg/L (detection limit. These results are probably related to the processing of vodka, in particular the use of extractive and rectifying stainless steel distillation columns, which allow the production of high strength spirits with low levels of congeners and contaminants.

  3. The role of interest rates in the Brazilian business cycles

    Nelson F. Souza-Sobrinho

    2011-09-01

    Full Text Available This paper offers additional insights on the relationship between interest rates and business cycles in Brazil. First, I document that Brazilian interest rates are very volatile, counter-cyclical and positively correlated with net exports, as observed in other emerging market economies. Next, I present a dynamic stochastic general equilibrium model in which firms face working capital constraints and labor supply is independent of consumption. This parsimonious model, appropriately calibrated to the Brazilian economy, predicts that interest rate shocks can explain about one third of output fluctuations and delivers business cycle regularities consistent with the Brazilian data.

    We report here the first complete mitochondria genome of Onchocerca volvulus from a focus outside of Africa. An O. volvulus mitogenome from the Brazilian Amazonia focus was obtained using a combination of high-throughput and Sanger sequencing technologies. Comparisons made between this mitochondrial genome and publicly available mitochondrial sequences identified 46 variant nucleotide positions and suggested that our Brazilian mitogenome is more closely related to Cameroon-origin mitochondria than West African-origin mitochondria. As well as providing insights into the origins of Latin American onchocerciasis, the Brazilian Amazonia focus mitogenome may also have value as an epidemiological resource.

    Eryptosis is a physiological phenomenon in which old and damaged erythrocytes are removed from circulation. Erythrocytes incubated with lead have exhibited major eryptosis. In the present work we found evidence of high levels of eryptosis in lead exposed workers possibly via oxidation. Blood samples were taken from 40 male workers exposed to lead (mean blood lead concentration 64.8 μg/dl) and non-exposed workers (4.2 μg/dl). The exposure to lead produced an intoxication characterized by 88.3% less δ-aminolevulinic acid dehydratase (δALAD) activity in lead exposed workers with respect to non-lead exposed workers. An increment of oxidation in lead exposed workers was characterized by 2.4 times higher thiobarbituric acid-reactive substance (TBARS) concentration and 32.8% lower reduced/oxidized glutathione (GSH/GSSG) ratio. Oxidative stress in erythrocytes of lead exposed workers is expressed in 192% higher free calcium concentration [Ca{sup 2+}]{sub i} and 1.6 times higher μ-calpain activity with respect to non-lead exposed workers. The adenosine triphosphate (ATP) concentration was not significantly different between the two worker groups. No externalization of phosphatidylserine (PS) was found in non-lead exposed workers (< 0.1%), but lead exposed workers showed 2.82% externalization. Lead intoxication induces eryptosis possibly through a molecular pathway that includes oxidation, depletion of reduced glutathione (GSH), increment of [Ca{sup 2+}], μ-calpain activation and externalization of PS in erythrocytes. Identifying molecular signals that induce eryptosis in lead intoxication is necessary to understand its physiopathology and chronic complications. - Graphical abstract: Fig. 1.

    Immigrant workers are a vulnerable and underserved population. The average life expectancy of the migrant worker is 49 years, compared to 77.2 years for most Americans. Immigrant workers have a higher disease burden than other populations and work in occupations with high hazard levels. In addition, they have low socioeconomic levels and face many barriers to accessing healthcare services. Undocumented immigrant workers are excluded in the Affordable Care Act. Health professionals must be attuned to the health issues of new immigrants so that they can provide better services. In order to raise the health standards of America, health professionals must provide healthcare for all, including immigrant workers.

    2009-12-01

    Full Text Available This article aims to discuss the profile that is required of workers in current forms of production. This is done by considering the productive restructuring process that took place in Brazil since the 1990’s. This process presents implications to different social organizations, especially to the State and the institutions related to it, for example the schools. The analysis of the primary and secondary sources related to the basic education reforms implemented in the same decade reveals the valuing of work competencies such as flexibility and the capacity to adapt. The article presents reflections on the rhetoric used to justify educational reforms, pointing out its underlying ideology and the actions performed by the Brazilian State, as well as the structural limits of the capitalist system for the social inclusion of the whole population.

    2014-01-01

    Full Text Available Corporate Social Responsibility practices have been on the rise in recent years in firms all over the world. Brazil, as one of the most important countries emerging on the international scene, is no exception to this, with more and more firms taking up these practices. The present study focuses on analyzing the corporate social responsibility practices that Brazilian companies engage into. The sample used is comprised of 500 firms grouped by geographical area; the theoretical framework is based on stakeholder and institutional theories; and the technique used for the analysis is the biplot, more specifically the HJ Biplot and cluster analysis. From the results obtained it is possible to infer that the CSR variables corresponding to environmental practices are more closely linked to companies located in the northern areas of Brazil. Social and community practices are related to companies primarily in the southern and northeastern regions of the country.

    The objective of this study was to identify the motives for sport participation in a sample of young Brazilian athletes according to sex, age, and training history. A total of 1,517 participants (714 girls, 803 boys) ages 12 to 18 years were included in the study. The Portuguese version of the Participation Motivation Questionnaire was used to identify motives for sport participation. The most important motives were Skill Development and Fitness, whereas the least important were Fun and Achievement/Status. Sex, age, type of sport, onset of training, duration of training, training volume, and competitive experience significantly influenced the motives for sport participation reported by the athletes. These results will contribute to establish intervention programs designed to reduce sport dropout rates among young athletes.

    Full Text Available Abstract: Currently the importance of using alternative strategies for biodiversity conservation is emphasized and since the establishment of germplasm bank is an alternative to the conservation of endangered species. This is a technique of great importance for the maintenance of Brazilian fauna. Since the early70'sthere was a growing concern about the need to preserve essential genetic resources for food and agriculture, mainly for conservation of genetic material from farm animals. Thus was created the Brasilia Zoo, in July 2010, the first Germplasm Bank of Wild Animals in Latin America, as an alternative strategy for the conservation of threatened or endangered species, using both gametes and somatic cells and stem cells. Then we argue to create new banks or research networks among different regions with aimed to tissue preservation.

  18. The multiplicity of Brazilian Social Psychology

    Directory of Open Access Journals (Sweden)

    Mariana Prioli Cordeiro

    2014-02-01

    Full Text Available Brazilian Social Psychology has many definitions, theories and objects of study. In this essay, based on Actor-Network Theory, we argue that these are not different aspects or attributes of a single object, but elements that help to perform different versions of this object. They are, therefore, elements that make Social Psychologies different, although related to each other. They produce a multiple Social Psychology, which is more than one and, at the same time, less than many. In doing so, we strived to call attention to the possibility of ordinating and coordinating reality in different ways, of recognizing that there are multiple and diverse actants in a discipline and of making a Social Psychology that searches for complex connections that articulate humans and non-humans and perform multiple realities.

    2008-01-01

    Full Text Available Brazilian spotted fever is caused by the bacterium Rickettsia rickettsii, which is the most pathogenic species of the spotted-fever rickettsiae group and is transmitted by the bite of infected ticks. Amblyomma cajennense is the most important tick species involved in the cycle of this zoonosis in Brazil as it presents low host specificity, great number of natural reservoirs and wide geographic distribution. It was first described in the state of São Paulo in 1929 and later in Rio de Janeiro, Minas Gerais and Bahia. The number of cases decreased in the 1940's with the development of new plague control techniques and antibiotics. In the last decades, the number of new cases has increased. The current review aimed at reporting some of the epidemiological and public health aspects of this reemergent disease with new foci, mainly in the southeastern region of Brazil.

    2015-07-01

    The XXXVII Brazilian Meeting on Nuclear Physics (or XXXVII RTFNB 2014) gave continuity to a long sequence of workshops held in Brazil, devoted to the study of the different aspects of nuclear physics. The meeting took place in the Maresias Beach Hotel, in the town of Maresias (state of São Paulo) from 8th to 12th September 2014. Offering gentle weather, a charming piece of green land of splendid natural beauty with beach and all amenities, the place had all the conditions for very pleasant and fruitful discussions. The meeting involved 162 participants and attracted undergraduate and graduate students, Brazilian and South American physicists and invited speakers from overseas (USA, Italy, Spain, France, England, Switzerland, Germany and South Corea). In the program we had plenary morning sessions with review talks on recent developments in theory, computational techniques, experimentation and applications of the many aspects of nuclear physics. In the parallel sessions we had a total of 58 seminars. This volume contains 60 written contributions based on these talks and on the poster sessions. Evening talks and poster sessions gave still more insight and enlarged the scope of the scientific program. The contributed papers, representing mainly the scientific activity of young physicists, were exhibited as posters and are included in the present volume. Additional information about the meeting can be found at our website: http://www.sbfisica.org.br/~rtfnb/xxxvii-en Support and sponsorship came from brazilian national agencies: Conselho Nacional de Desenvolvimento Científico e Tecnoógico (CNPq); Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES); Fundação de Amparo á Pesquisa do Estado de São Paulo (FAPESP); Fundação de Amparo á Pesquisa do Estado do Rio de Janeiro (FAPERJ); Sociedade Brasileira de Física (SBF) and Instituto de Física da Universidade de São Paulo (IFUSP).

    The identification of cytogenetic abnormalities in schizophrenic patients may provide clues to the genes involved in this disease. For this reason, a chromosomal analysis of samples from 62 schizophrenics and 70 controls was performed with trypsin-Giemsa banding and fluorescence in situ hybridization of the X chromosome. A clonal pericentric inversion on chromosome 9 was detected in one male patient, and we also discovered mosaicism associated with X chromosome aneuploidy in female patients, primarily detected in schizophrenic and normal female controls over 40 years old. When compared with age-matched female controls, the frequency of X chromosome loss was not significantly different between schizophrenics and controls, except for the 40- to 49-year-old age group. Our findings suggest that the X chromosome loss seen in schizophrenic patients is inherent to the normal cellular aging process. However, our data also suggest that X chromosome gain may be correlated with schizophrenia in this Brazilian population.

    Sixteen extracts, obtained from eight Brazilian plants of Annonaceae family, were screened for their antibacterial activity: Xylopia frutescens, X. aromatica, X. amazonica, X. benthamii, Annona ambotay, A. crassiflora, A. muricata and A. cherimolia. Amongst the investigated extracts, six showed antibacterial activity against at least one of the tested organisms at the concentration of 100 microg/mL. The most active extracts were those prepared from X. frutescens, X. amazonica, and A. ambotay. A phytochemical screening showed the presence of anonaceus acetogenins in some active extracts. Eleven diterpenoids were also tested for comparison purposes. Six were natural products, previously isolated from Xylopia sp. (kaurenoic, frutoic, xylopic, 15beta-hydroxy-kaurenoic and trachylobanic acids plus kaurenol) and five were derivatives of such compounds, obtained by esterification or reduction reactions. Trachylobanic acid showed antibacterial activity against B. subtilis and S. aureus.

    Results and discussion: Age at diagnosis was between 10 and 32 months and the severity of the disease correlated with the increasing of age at diagnosis. The predominant symptoms were vomiting, weight loss, and hepatomegaly. Severe renal tubular acidosis manifested in one child. All patients had remission of symptoms after dietary modification. The sequencing of the ALDOB gene identified one homozygous patient for the mutation c.524C>A (p.A175D, while the others were compound heterozygous for c.360_363delCAAA (p.N120KfsX32, c.178C>T (p.R60X mutations, c.448G>C (p.A150P and c.524C>A (p.A175D. Clinical improvement of patients after dietary treatment is suggestive of the diagnosis, confirmed by molecular analysis. The prevalence of mutations found in our Brazilian patients is different from those of international literature.

    This work deals with a computational investigation on the small ballistic reentry Brazilian vehicle SARA (acronyms for SAt\\'elite de Reentrada Atmosf\\'erica). Hypersonic flows over the vehicle SARA at zero-degree angle of attack in a chemical equilibrium and thermal non-equilibrium are modeled by the Direct Simulation Monte Carlo (DSMC) method, which has become the main technique for studying complex multidimensional rarefied flows, and that properly accounts for the non-equilibrium aspects of the flows. The emphasis of this paper is to examine the behavior of the primary properties during the high altitude portion of SARA reentry. In this way, velocity, density, pressure and temperature field are investigated for altitudes of 100, 95, 90, 85 and 80 km. In addition, comparisons based on geometry are made between axisymmetric and planar two-dimensional configurations. Some significant differences between these configurations were noted on the flowfield structure in the reentry trajectory. The analysis showed t...

  6. Aging, Gender and Sexuality in Brazilian Society

    2014-04-01

    Full Text Available Drawing on the interplay between gender, aging, and sexuality, the aim of this article is twofold: (1 to show how Brazilian gerontologists treat gender differences and sexual activity in old age; (2 to analyze the  ways  discourses regarding the aging body and sexuality are perceived and evaluated by older women and men . I argue that  attempts of gerontologists’ to eroticize old age have to contend with the widespread notion that the desire for sex is inevitably lost with age. Thus, in the retiree associations that were studied, men had a tendency to assume they are not ‘old’ because their erectile function was still in good condition, and divorced or widowed women, in senior citizen associations, tend to regard themselves as happy due to having freed themselves from the sexual obligations imposed by marriage. In both cases, the dominant belief that there is a loss of sexual desire in old age was reproduced.

    Power Grids and other delivery networks has been attracted some attention by the network literature last decades. Despite the Power Grids dynamics has been controlled by computer systems and human operators, the static features of this type of network can be studied and analyzed. The topology of the Brazilian Power Grid (BPG) was studied in this work. We obtained the spatial structure of the BPG from the ONS (electric systems national operator), consisting of high-voltage transmission lines, generating stations and substations. The local low-voltage substations and local power delivery as well the dynamic features of the network were neglected. We analyze the complex network of the BPG and identify the main topological information, such as the mean degree, the degree distribution, the network size and the clustering coefficient to caracterize the complex network. We also detected the critical locations on the network and, therefore, the more susceptible points to lead to a cascading failure and even to a blac...

    First Brasflux Workshop; Santa Maria, Rio Grande do Sul, Brazil, 14-15 November 2011 Last November, 33 researchers participated in a workshop to establish Brasflux, the Brazilian network of carbon flux stations, with the objective of integrating previous efforts and planning for the future. Among the participants were those leading ongoing flux observation projects and others planning to establish flux stations in the near future. International scientists also participated to share the experiences gained with other networks. The need to properly characterize terrestrial ecosystems for their roles in the global carbon, water, and energy budgets has motivated the implementation of hundreds of micrometeorological research sites throughout the world in recent years. The eddy covariance (EC) technique for turbulent flux determination is the preferred method to provide integral information on ecosystematmosphere exchanges. Integrating the observations regionally and globally has proven to be an effective approach to maximizing the usefulness of this technique for carbon cycle studies at multiple scales.

    The digital, decimetric (950-2500 MHz) Brazilian Solar Spectroscope (BSS, Sawant, H.S., Subramanian, K.R., Faria, C., et al. Brazilian Solar Spectroscope (BSS). Solar Phys. 200, 167-176, 2001) with high time (10-1000 ms) and frequency (1-10 MHz) resolution is in regular operation since April, 1998, at the National Space Research Institute (INPE) at São José dos Campos, Brazil. The BSS has now been upgraded with a new digital data acquisition and data processing system. The new version of the BSS has improved the observational possibilities with the capability to record up to 200 frequency channels available in the selectable frequency range 950-2500 MHz. The GPS receiver permits the acquisition of data with time accuracy in the order of 0.1 ms. The software system of the BSS is composed by two distinct modules: the first, data acquisition system provides a flexible Graphical User Interface (GUI) that allows one to choose the observational parameters. The second module is the real time visualization system that permits real time visualization of the observed dynamic spectrum and additionally allows procedures for visualization and preliminary analysis of the recorded solar spectra. Using the new visualization system, we have realized two new types of dm-radio fine structures: narrow band type III bursts with positive as well as negative group frequency drift and dots emissions arranged in zebra-like and fiber-like chains. Furthermore, we have found flare generated fast wave trains according to their tadpole signature in wavelet power spectra for a decimetric type IV radio event (June 6, 2000 flare).

    Full Text Available Investigates the theme known as “Knowledge Management” (KM in three large Brazilian organizations trying to discuss its concepts, constituent elements, managerial approaches and tools, while aiming at leaving behind the purely terminological discussion, which is innocuous and naive. The basic presuppositions were two: (i most of what it´s referred to or named KM is actually “Information Management” (IM and IM is just one of the components of KM. KM is more than simply IM due to the fact that it includes and incorporates other concerns, such as the creation, use and sharing of information and knowledge in the organizational context; (ii a conceptual model or map can be formulated based on three basic conceptions: (a a strategic conception of information and knowledge, (b the introduction of such strategy in the tactical and operational levels through the several managerial approaches and informaion technology tools and (c the creation of an organizational space for knowledge. The main objective is to investigate and analyze the conceptions, motivations, practices and results of KM effectively implemented in three large Brazilian organizations. The qualitative research strategy used was the study of multiple cases with incorporated units of analysis and three criteria ere observed for the judgment of the quality of the research project: validity of the construct, external validity and reliability. Multiple sources of evidence were used and data analysis consisted of three flows of activities: data reduction, data displays and conclusion drawing/verification. The results confirmed the presuppositions and the fact that KM means a rethinking of management practices in the information ea. It was also identified that the main challenges facing organizations committed to KM have its focus on change management, cultural and behavioral issues and the creation of an enabling context that favors the creation, use and sharing of information and

    Rock, soil and water contain {sup 238}U, {sup 232}Th and their decay products. The distribution of these radionuclides differs in terms of activity concentration depending on the mineral type and origin. All ore processing releases long and short half-life radionuclides, mainly radon and its progeny. It is important to monitor this gas and its products in underground mines in order to assess the radiological hazards of the exposed workers. On this concern, the present work outlines the characterization of the radon and its progeny concentration in the brazilian underground mines. The radon concentration was measured by using E-PERM Electrets Ion Chamber, AlphaGUARD and CR-39 track etch detectors. The radon progeny was determined by using DOSEman detector. The equilibrium state between radon and its progeny was calculated. Based on these data, the annual effective dose for miners was estimated according to UNSCEAR 2000 methodology. Moreover, the contribution from the main sources to the radon level inside mines was evaluated. For this, the following detectors were used: concentration measurements of the soil gas radon were carried out by AlphaGUARD detector; {sup 226}Ra ({sup 214}Bi) specific activity in ore and soil samples were determined by gamma-ray spectrometry HPGe detector; and radon concentration in groundwater samples was performed by RAD7 detector. The radon concentration ranged from 113 to 8171 Bq.m{sup -3} and the Equilibrium Equivalent Concentration varied from 76 to 1174 Bq.m{sup -3}. The general measurement results and the estimated effective doses will be used as bases to prepare the brazilian regulatory standards. (author)

    The air transportation network in a country has a great impact on the local, national and global economy. In this paper, we analyze the air transportation network in Brazil with complex network features to better understand its characteristics. In our analysis, we built networks composed either by national or by international flights. We also consider the network when both types of flights are put together. Interesting conclusions emerge from our analysis. For instance, Viracopos Airport (Campinas City) is the most central and connected airport on the national flights network. Any operational problem in this airport separates the Brazilian national network into six distinct subnetworks. Moreover, the Brazilian air transportation network exhibits small world characteristics and national connections network follows a power law distribution. Therefore, our analysis sheds light on the current Brazilian air transportation infrastructure, bringing a novel understanding that may help face the recent fast growth in the usage of the Brazilian transport network.

    This paper investigates price fluctuations in the Brazilian stock market. We employ a recently developed methodology to test whether the Brazilian stock price returns present a power law distribution and find that we cannot reject such behavior. Empirical results for sub-partitions of the time series suggests that for most of the time the power law is not rejected, but that in some cases the data set does not conform with a power law distribution.

    This paper presents the major characteristics of the Brazilian tax system, after underlining the modifications it went through since 1988, when the country adopted a new and democratic Constitution. One important feature is the marked incidence of indirect consumer and production taxes (49% of all tax revenues) in place of direct taxes on income, inheritance, and capital gains. This imbalance between indirect and direct taxes explains, in large part, the elevated regressivity of the Brazilian...

    Full Text Available BACKGROUND: Due to recent industrialization and inadequately protected workers or in other words poor supervision on constructive workers habits in our large city of Isfahan cement contact dermatitis is relatively high especially among cement factory workers and constructive personnel. PURPOSES: To investigate the prevalence rate of cement contact dermatitis in cement factory workers in Isfahan. METHODS: A case-control clinical study was carried out by randomly selecing 150 factory workders and 150 official clerks in a cement factory in Isfahan in 2001. After a complete physical examination, data was recorded in observational checklists. FINDINGS: The percentages of contact dermatitis prevalences in the first and the second groups were 22% and 5.3% respectively. About 60% of cement workers with contact dermatitis were between 30-40 years of age. There was a direct relationship with age in both groups of the workers. In the high-exposure group, the hand eczema along was 70% but in the other group the percentage of involvement was the same in exposed and unexposed anatomical areas. CONCLUSIONS: There was a direct relationship between occurrence and the severity of involvement and duration of contact in the first group. Cent percent of cement workers had contact dermatitis after 10 or less years, but the percentage among the other group was 35%. LIMITATION: Irritant contact dermatitis to cement has not been detected.

    Full Text Available National surveys are relevant for the study of sleep epidemiology since they can provide specific data about sleep in large dimension with important implications for the health system. Thus, the aim of this study was to investigate the prevalence of sleep complaints among the Brazilian population using a randomized cluster sample according to region and socioeconomic class. For this, a 3-stage sampling technique was used to randomly select Brazilian subjects of both genders older than 16 years. A total of 2017 subjects, from 132 different cities, were selected to estimate prevalence in the Brazilian population with a sampling error of ±2%. Questions about sleep complaints were administered face-to-face by Instituto Datafolha interviewers on April 10 and 16, 2012. Data were expanded using a weighted variable. The results showed that 76% of the study population suffers from at least 1 sleep complaint, indicating that approximately 108 million Brazilians may be affected by sleep disorders. On average, each subject had 1.9 sleep problems with the most common complaints being light and insufficient sleep, snoring, moving a lot during sleep, and insomnia, which usually occurred more than 3 times per week. Low income was associated with higher number of sleep complaints only in Northeast and Southeast regions. In conclusion, this study showed a high prevalence of sleep complaints in a sample of the Brazilian population, suggesting that sleep disorders may be markedly frequent in the Brazilian population with a possible correlation with the socioeconomic situation of the interviewed subjects.

    Full Text Available Scorpion stings are a major public health problem in Brazil, with an increasing number of registered cases every year. Affecting mostly vulnerable populations, the phenomenon is not well described and is considered a neglected disease. In Brazil, the use of anti-venom formulations is provided free of charge. The associate scorpion sting case is subject to compulsory reporting. This paper describes the epidemiology and identifies factors associated with severity of scorpions stings in the state of Amazonas, in the Western Brazilian Amazon.This study included all cases of scorpion stings in the state of Amazonas reported to the Brazilian Diseases Surveillance System from January 1, 2007 to December 31, 2014. A case-control study was conducted to identify factors associated with scorpions sting severity. A total of 2,120 cases were reported during this period. The mean incidence rate in the Amazonas was 7.6 per 100,000 inhabitants/year. Scorpion stings showed a large spatial distribution in the state and represent a potential occupational health problem for rural populations. There was a positive correlation between the absolute number of cases and the altimetric river levels in the Central (p<0.001; Rs = 0.479 linear and Southwest (p = 0.032; linear Rs = 0.261 regions of the state. Cases were mostly classified as mild (68.6%, followed by moderate (26.8%, and severe (4.6%. The overall lethality rate was 0.3%. Lethality rate among children ≤10 years was 1.3%.

Cases were mostly classified as mild (68.6%), followed by moderate (26.8%), and severe (4.6%). The overall lethality rate was 0.3%. Lethality rate among children ≤10 years was 1.3%. Age <10 years [OR = 2.58 (95%CI = 1.47–4.55; p = 0.001)], stings occurring in the rural area [OR = 1.97 (95%CI = 1.18–3.29; p = 0.033) and in the South region of the state [OR = 1.85 (95%CI = 1.17–2.93; p = 0.008)] were independently associated with the risk of developing severity. Conclusions/Significance Scorpion stings show an extensive distribution in the Western Brazilian Amazon threatening especially rural populations, children ≤10 in particular. Thus

    Full Text Available To date, shift workers represent between 15% and 25% of the modern day workforce. Work time poses a great challenge to workers as it requires that they balance productivity and sleep time between shifts. As a result, these workers experience chronic sleep deprivation with increased fatigue and drowsiness due to this sleep deprivation. The impact of this kind of work on the immune system is not yet known. We conducted a literature review with the aim of evaluating articles on this specific type of work's effects on sleep and immunity.

    Full Text Available Motivation is one of the most important factors influencing workers' productivity. An increase in workers' motivation could add more value to organizations' structure and influence the profitability, significantly. In this paper, we study different factors on demotivating workers using questionnaire consist of various questions. The questionnaire is distributed among some employees who work for rubber production units located in Esfahan, Iran. The results of this survey indicate that discrimination on annual job compensation, entrusting responsibilities and unpleasant relationship with family partner are some of the most important factors influencing employees' motivation. While financial factors play important role on increasing employees' motivation, non-financial factors are considered more important.

    Full Text Available The Brazilian penitentiary system has many flaws, which involve the treatment of the prisoners, and also the work situation of the professionals in this setting. This fact led to this investigation, which had as a purpose to identify the presence of stress due to labor activities, assess the quality of life of the workers and correlate the dimensions of quality of life to occupational stress among the prison officers. This is a descriptive, transversal and quantitative research , carried out with  35 workers (70% of the universes working in the prison system of the municipality of  Cajazeiras, Paraiba after the approval  of the Research Ethics Committee of the Faculty of Santa Maria (protocol number 815.685. For the data collection the World Health Organization Quality of Life – Bref (WHOQOL-Bref and the Job Stress Scale (JSS were used. The data was analyzed through the descriptive and inferential statistics. In the comparison between the quality of life and work-related stress domains, the Friedman test was used and to control the error effect Bonferroni's test was carried out. The results, regarding occupational stress, indicated that the psychological demand was what presented the highest score (3.74 and lack of control over work the lowest one (2.71. The total level of quality of life of the prison officers presented an average of 71.07, with the highest score being for the social domain (76.90 points and the lowest score for the environmental domain (62.23 points. When correlating the quality of life with stress, there was a negative and significant correlation of the total quality of life with the lack of control over work (ρ = -0.42; p <0.05 and with the total stress (ρ = -0.41; p <0.05 showing that the higher the levels of stress, lower the quality of life level. Despite the quality of life having been adequate, the environmental domain has led to its reduction, as well as the occupational stress, being this factor more affected

    Full Text Available Tooth loss continues to be a prevalent condition in Brazilian adults and elderly individuals. The aim of this cross-sectional study, conducted among workers in a wholesale grocery chain in the State of São Paulo, was to identify risk indicators for tooth loss in adults. The presence of caries and periodontal status were examined in 387 adults aged 20-64 years, according to World Health Organization criteria. Two outcomes were analyzed: loss of one or more teeth, and loss of four or more teeth. Independent variables analyzed were demographic and socioeconomic factors, clinical conditions, use of dental services, and self-perceived oral health. Poisson regression models were used for multivariate statistical analysis. Participants were missing a mean of 5.38 teeth, and 76.9% (n = 297 had lost at least one tooth; the most frequently lost teeth were permanent molars. Older age and the presence of visible dental biofilm were associated significantly with the two tooth loss outcomes (p < 0.05. Individuals who had visited the dentist 3 or more years previously showed a lower prevalence of tooth loss (prevalence ratio = 0.79; 95% confidence interval, 0.68-0.91. Those with lower household incomes were significantly more likely to have lost four or more teeth (prevalence ratio = 1.35; 95% confidence interval, 1.07-1.70. Study results indicated that age and dental biofilm were risk indicators for tooth loss, independently of socioeconomic factors. These risk indicators should be considered when planning oral health programs for adults.

    Food stamps and meal vouchers can determine workers' dietary choices. The study aimed to assess the coverage of these benefits in Brazil and their distribution according to the beneficiaries' socio-demographic and regional characteristics, using data from the Brazilian Household Budgets Survey, 2008-2009. Eligibility criteria were having an occupation and a private or government job, including domestic or temporary work in rural areas. Only 3.2% of eligible individuals reported receiving such benefits. Highest coverage rates were verified with the Southeast region, urban areas, male gender, employment in the private sector, and monthly earnings > five times the minimum wage. The mean monthly amount of such benefits was R$ 177.20 (US$ 100 at the 2009 exchange rate). After adjusting for other variables, the highest amounts were associated with male gender, higher salaries, the Northeast and Central regions, and employment in the public sector. This first analysis of the national coverage of food stamps and meal vouchers showed that a large share of Brazilian workers lack access or have unequal access to such benefits.

    Sex workers constitute a heterogeneous group possessing a combination of vulnerability factors such as geographical instability, forced migration, substance addiction and lack of legal residence permit. Access to healthcare for sex workers depends on the laws governing the sex market and on migration policies in force in the host country. In this article, we review different European health strategies established for sex workers, and present preliminary results of a pilot study conducted among 50 sex workers working on the streets in Lausanne. The results are worrying: 56% have no health insurance, 96% are migrants and 66% hold no legal residence permit. These data should motivate public health departments towards improving access to healthcare for this vulnerable population.

    Full text of publication follows: Gamma radiation from radionuclides which are characterized by half lives comparable to the age of the earth, such as 40 K and the radionuclides from the 238 U and 232 Th series, and their decay products, represent the main terrestrial source of irradiation to the human body. Their concentrations vary for different types of rocks, where high radiation levels are associated with igneous rocks such as granite. Thorium, uranium and potassium concentrations of granitic rocks are intimately related to their mineral compositions and general petrologic features. Then, these features associated with effects of weathering and metamorphism produce expressive alterations in the relationship between the natural radionuclides (Th, U, K, Th/U and Th/K). Consequently, the measurements of thorium, uranium, and potassium concentrations of different granite samples result on individual differentiation sequences. From the 232 Th, 238 U and 40 K activity concentrations obtained for each sample, it is possible to evaluate their respective dose rates in air, when these stones are used as tiling rocks. These results are of great interest in the environmental radiological protection study, since granites are widely used as building and ornamental materials, including as indoor covering. In this way, the Laboratory of Radioecology (L.A.R.A.) of the Physics Institute of the Universidade Federal Fluminense (I.F. -U.F.F.) has been performing analyzes on more than one hundred differ ent types of the main Brazilian commercial granites in last two years [1]. Using NaI and HP Ge gamma-ray spectrometers to determine the concentration of natural radionuclides in these samples, the annual effective dose rates and the gamma activity concentration index have been evaluated and compared to the limits proposed by United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) and European Commission (E.C.). In addition, the correlations between thorium

    OBJECTIVE To determine the distribution of total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides in Brazilian adolescents, as well as the prevalence of altered levels of such parameters. METHODS Data from the Study of Cardiovascular Risks in Adolescents (ERICA) were used. This is a country-wide, school-based cross-sectional study that evaluated 12 to 17-year old adolescents living in cities with over 100,000 inhabitants. The average and distribution of plasma levels of total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides were evaluated. Dyslipidemia was determined by levels of total cholesterol ≥ 170 mg/dl, LDL cholesterol ≥ 130 mg/dl, HDL cholesterol < 45 mg/dL, or triglycerides ≥ 130 mg/dl. The data were analyzed by gender, age, and regions in Brazil. RESULTS We evaluated 38,069 adolescents - 59.9% of females, and 54.2% between 15 and 17 years. The average values found were: total cholesterol = 148.1 mg/dl (95%CI 147.1-149.1), HDL cholesterol = 47.3 mg/dl (95%CI 46.7-47.9), LDL cholesterol = 85.3 mg/dl (95%CI 84.5-86.1), and triglycerides = 77.8 mg/dl (95%CI 76.5-79.2). The female adolescents had higher average levels of total cholesterol, LDL cholesterol, and HDL cholesterol, without differences in the levels of triglycerides. We did not observe any significant differences between the average values among 12 to 14 and 15- to 17-year old adolescents. The most prevalent lipid alterations were low HDL cholesterol (46.8% [95%CI 44.8-48.9]), hypercholesterolemia (20.1% [95%CI 19.0-21.3]), and hypertriglyceridemia (7.8% [95%CI 7.1-8.6]). High LDL cholesterol was found in 3.5% (95%CI 3.2-4.0) of the adolescents. Prevalence of low HDL cholesterol was higher in Brazil's North and Northeast regions. CONCLUSIONS A significant proportion of Brazilian adolescents has alterations in their plasma lipids. The high prevalence of low HDL cholesterol and hypertriglyceridemia, especially in Brazil's North and Northeast regions, must be

    ABSTRACT OBJECTIVE To describe the prevalence of asthma and physician-diagnosed asthma in Brazilian adolescents. METHODS Cross-sectional, national, school-based study with adolescents from 12 to 17 years old, participants in the Study of Cardiovascular Risks in Adolescents (ERICA). The study stratified the sample by region and grouped according to schools and classes with representativeness to the set of cities with more than 100,000 inhabitants of the Country, macro-regions, capitals, and Federal District. A questionnaire collected data through a self-filled in method. We calculated the prevalences and their confidence intervals of 95% (95%CI) according to sex, age group, type of school and skin color. RESULTS Between 2013 and 2014, 74,589 adolescents were evaluated, 55.3% of the female sex. The total prevalence of active asthma was of 13.1% (95%CI 12.1-13.9), being higher in girls (14.8%; 95%CI 13.7-16.0) when compared to boys (11.2%; 95%CI 10.3-12.2) in all geographical strata examined. It was also higher between students of private schools (15.9%; 95%CI 14.2-17.7) when compared to public ones (12.4%; 95%CI 11.4-13.4). It was higher in the Southeast region (14.5%; 95%CI 12.9-16.1), and in the city of Sao Paulo (16.7%; 95%CI 14.7-18.7). The lowest prevalence was observed in North region (9.7%; 95%CI 9.7-10.5), and in Teresina (6.3%; 95%CI 4.9-7.7). The prevalence of physician-diagnosed asthma was of 8.7% (95%CI 8.2-9.1); higher in the North region (13.5%; 95%CI 12.7-14.2), and in Porto Alegre (19.8%; 95%CI 17.5-22.3). It was lower in the Midwest (6.9%; 95%CI 6.0-7.8), and in Cuiaba (4.8%; 95%CI 3.8-5.9). We found no significant difference in the expression of this rate between the sexes, as well as in other variables evaluated by the study. CONCLUSIONS The prevalence of asthma in Brazilian adolescents is high. Rates of active asthma and physician-diagnosed asthma vary widely in different regions and capitals evaluated by the ERICA. These results may assist in the

  5. Migrant workers: victims of war in Gulf.

    Science.gov (United States)

    1992-01-01

    The Persian Gulf War forced millions of migrant workers in the region to return home, causing hardship not only on the workers but also on their home countries. Prior to the war, the region's oil wealth had attracted migrants from around the world. By 1990, some 3 million resided in Iraq and Kuwait alone. Many more worked in other Gulf countries. But only 2 months after the Iraqi invasion of Kuwait, over 2 million workers had fled the region or had been returned home. Yemenis and Egyptians alone accounted for 750,000 and 1/2 million workers, respectively. There were also an estimated 600,000 Asians. Although many of the migrants were unskilled laborers, many also were skilled laborers and professionals. Jordanians and Palestinians made up much of the Kuwaiti civil service. As the war unfolded, it became clear that the migrant workers lacked any of the legal rights and protection granted to other citizens. Many workers were not allowed to return home because of their importance to the economy. Others, like some 35,000 Sri Lankan housemaids in Kuwait, were stranded in the war zone, lacking the money and means to return home. In most cases, the workers also suffered from frozen bank accounts, unpaid wages and benefits, and property loss. Their return home also created problems for their countries. Jordan's population increased by 10% in 1990 due to the returning population. Yemen's unemployment increased from 10% to 25%. As a result of the Gulf war experience, the UN General Assembly adopted the International Convention on the Rights of Migrant Workers and their Families, which must now be ratified by 20 nations before implementation begins.

    2003-06-01

    An estimated 300.000 migrant workers are currently living in Israel, which is about 5% of the general population. More then half of this population is undocumented and have very limited access to public health care. Due to the financial difficulties within the Israel's public health system, the entity is unable to deal with the needs of migrant workers. Hence, when these migrant workers need inpatient care, hospitals have to bear the costs and this situation creates a divergence between medical and economic considerations. The open clinic of "Physicians for Human Rights", which is operated by volunteer physicians and nurses, is able to provide medical aid for mild and transient illnesses, but not for chronic diseases. Israeli physicians are regularly confronted with ethical issues, regarding the therapy they would like to provide to undocumented migrant workers, but are unable to do so. In Europe, undocumented migrant workers have better access to public health care than in Israel. The Israeli public health system should permit all migrant workers to insure themselves at affordable prices, or another inexpensive insurance system should be created for them.

    Although known neurotoxins with potential ophthalmotoxic properties are commonly used in microelectronics assembly, there has been no systematic study of visual disturbances among past or present workers in this industry. The objective of the present study was to compare visual functions, using a matched-pair design, between former workers from a microelectronics plant and a local reference population. From an initial population of 180 former workers and 157 potential referents, 54 pairs were matched for age (+/- 3 y), education (+/- 2 y), sex, ethnic origin, and number of children. Near and far visual acuity, chromatic discrimination, and near contrast sensitivity were assessed monocularly. Paired comparisons (Signed-rank Wilcoxon test) revealed that the former microelectronics workers had significantly lower contrast sensitivity, particularly in the intermediate frequencies, independently of near visual acuity loss. There were no differences for far visual acuity in both eyes. Even though near visual acuity and color vision were compromised among the former workers, the differences were only significant for one eye, as was the prevalence of acquired dyschromatopsia (chi-square for matched pairs, p less than .001). These findings suggest a pattern of contrast sensitivity deficits consistent with impairment to foveal and/or neuro-optic pathways among these former microelectronics workers. Exposure to ophthalmotoxic chemicals is proposed as the most probable risk factor.

    1991-01-01

    Although chemicals posing potential neurotoxic hazards are commonly used in the microelectronics industry, there has been no systematic study of possible chronic nervous system effects in microelectronics workers. The objective of the present study was to assess neuropsychological functions of a group of former microelectronics plant assembly workers and a group of referents, using a matched pair design. During employment, the former microelectronics workers had been exposed to multiple organic solvents, including trichloroethylene, xylene, chlorofluorocarbons and trichloroethane. Referents were recruited from the same geographic region. From a pool of 180 former workers and 157 referents, 67 pairs were matched on the basis of age, sex, ethnicity, educational level, sex and number of children. Comparison of results on the subtests of the California Neuropsychological Screening Battery-Revised (CNS-R) revealed significantly lower performance by the former microelectronics workers on tests of attention/concentration, verbal ability, memory functions, visuospatial functions, visuomotor speed, cognitive flexibility, psychomotor speed, and reaction time (t-test for pairs or Wilcoxon Signed Rank p less than 0.05). No significant differences were observed for performance on tests assessing mental status, visual recall, tactile function and learning. This overall pattern of impairment is consistent with organic solvent-related chronic toxic encephalopathy, and possible early stages of dementia. These findings underline the need for more studies among workers currently or previously employed in microelectronics industries.

    Healthcare workers (HCW) have high exposure to infectious diseases, some of which, such as rubella, are vaccine-preventable. The aim of this study was to determine the immunity of HCW against rubella. We performed a seroprevalence study using a self-administered survey and obtained blood samples to determine rubella Immunoglobulin G (IgG) antibody levels in HCW during preventive examinations by five Primary Care Basic Prevention Units and six tertiary hospitals in Catalonia. Informed consent was obtained. IgG was determined using an antibody capture microparticle direct chemiluminometric technique. The odss ratio (OR) and 95% confidence intervals (CI) were calculated. Logistic regression was made to calculate adjusted OR. Of 642 HCW who participated (29.9% physician, 38.8% nurses, 13.3% other health workers and 18% non-health workers), 46.6% were primary care workers and 53.4% hospital workers. Of total, 97.2% had rubella antibodies. HCW aged 30-44 years had a higher prevalence of antibodies (98.4%) compared with HCW agedrubella antibodies is high in HCW, but workers agedrubella.

    New generation migrant workers have become mainstay of China’s migrant workers and also major builders of China’s urbanization process. Compared with last generation migrant workers,new generation migrant workers have greater awareness of starting an undertaking. In the new trend,undertaking-starting is inevitable for new generation migrant workers. This study analyzed problems encountered by new generation migrant workers in the course of starting an undertaking. It reached conclusions that competent authorities should set up support mechanism in undertaking-starting training,undertaking-starting fund,service platform,and preferential policies,to encourage and support new generation migrant workers to start an undertaking.

    Informal workers in Thailand lack employee status as defined under the Labor Protection Act (LPA). Typically, they do not work at an employer's premise; they work at home and may be self-employed or temporary workers. They account for 62.6 percent of the Thai workforce and have a workplace accident rate ten times higher than formal workers. Most Thai Labor laws apply only to formal workers, but some protect informal workers in the domestic, home work, and agricultural sectors. Laws that protect informal workers lack practical enforcement mechanisms and are generally ineffective because informal workers lack employment contracts and awareness of their legal rights. Thai social security laws fail to provide informal workers with treatment of work-related accidents, diseases, and injuries; unemployment and retirement insurance; and workers' compensation. The article summarizes the differences in protections available for formal and informal sector workers and measures needed to decrease these disparities in coverage.

    Full Text Available The present article presents different phases that the Brazilian Defense Ministry has passed through, since its inception during Fernando Henrique Cardoso's second presidential term (1999-2002 until the current administration of Luís Inácio Lula da Silva (2003-2006, under its respective ministers of Defense. It has been seen as one of the important stages in the re-constitutionalization of the country, insofar as it establishes the submission of Armed Forces commanders to a civilian minister, and although some analysts have considered that such submission is actually achieved, we point here to the military resistance and insubordination to civil power that are the result of an authoritarian legacy. To the extent that the Ministry of Defense is unable to implement its own policies in which the military would be required to follow civilian guidance, this article concludes with considerations on the civil Defense Ministry's political and institutional fragility vis-a-vis military command. The latter has been able to retain high levels of decision making autonomy in its relationship to the Ministry and its structure.

    Full Text Available Most of the recent astonishing export growth in Brazil came from firms which already exported. The export base was not able to grow at the same pace. Since expanding the export base may have several positive effects on firms' productivity and size, in this paper we provide a four-level classification of Brazilian industrial firms according to their potential to export, and we identify a subset of non-exporting firms which are potential exporters. The effects of export stimulating policies may be improved by focusing more closely on these firms.O recente crescimento das exportações no Brasil se baseou fortemente naquelas firmas já exportadoras, e a base exportadora não conseguiu acompanhar o mesmo ritmo de crescimento. Considerando que expandir a base exportadora pode ter efeitos positivos sobre a produtividade e tamanho das firmas, neste artigo classificamos as firmas industriais brasileiras em quatro níveis de acordo com o potencial exportador, e especialmente identificamos um subconjunto de firmas que não exportam mas que são potenciais exportadoras. Os efeitos das políticas de promoção às exportações podem ser maximizados se elas forem focalizadas nestas firmas.

    Including students' perceptions in the educational process is considered a key component in monitoring the quality of academic programs. This study aimed to evaluate the concept of one's learning experience in endodontic teaching from the perspective of a group of Brazilian students. A total of 126 self-administered, structured questionnaires were distributed to undergraduate dental students enrolled in endodontics courses during the second semester of the 2009 academic year. The questionnaires were administered during final examinations and focused on students' opinions concerning learning during endodontic treatments, time spent during endodontic treatments, difficulties found during endodontic treatments, quality of endodontic treatments performed, characteristics of the technique employed, and suggestions to improve endodontic teaching. Ninety-one percent of the questionnaires were returned for evaluation. The obtained answers were discussed and analyzed, thereby generating quantitative and qualitative data showing students' perceptions of their experiences in endodontics courses. The main points that can affect the teaching of endodontics, according to the undergraduate students, included patients' absences and delays, selection of patients, preclinical and clinical training, difficulties found, type of technique employed, and teachers' orientation during endodontic treatment. The students' perceptions provided valuable information about the development of the course and the teacher-student relationship, together with the added intention of enhancing the teaching of endodontics as well as other courses.

    2012-10-01

    Full Text Available This paper analyzes the phenomenon known as accrual anomaly in Brazil. In particular, we examine two hypotheses: (a that the earnings expectation included in the stock price fails to reflect the difference in persistence of the earnings components (accruals and cash flows; and (b that the construction of a hedge portfolio by taking a long (short position in assets with low (high accruals generates consistently abnormal returns. The data set includes nonfinancial firms listed on the BM&FBOVESPA between 1990 and 2008. The empirical tests required conducting panel data regressions to identify the persistence of earnings and theircomponents; the Mishkin test to identify whether the market rationally prices earnings; and the composition of a zero-investment (hedge portfolio to analyze whether a trading strategy based on accruals consistently provides abnormal positive returns. The results indicate that the accrual component is not mispriced by the Brazilian market, and that a trading strategy based on accruals does not provide consistently positive returns. Although this evidence does not encourage arbitrage, the results are relevant from various perspectives. The methodology applied permitted identifying the quality of earnings and of their components, as well as association between the components of earnings and returns.

    Full Text Available Although phenolic compounds produced by lichens have been widely investigated in antitumor assays, only a small number have been evaluated for mutagenicity and genotoxicity. This study evaluated protocetraric, hypostictic, psoromic, and salazinic acids for their potential genotoxic or antigenotoxic activity against somatic cells of Drosophila melanogaster. These compounds were isolated from the lichens Parmotrema dilatatum, Pseudoparmelia sphaerosphora, Usnea jamaicensis, and Parmotrema cetratum, respectively, collected from the Brazilian Cerrado biome. The compounds were evaluated at 0.75, 1.5, 3.0, and 6.0 mmol L–1 using the SMART test, employing standard and high-bioactivation crosses of Drosophila melanogaster. Doxorubicin (DXR was the positive control. Psoromic and salazinic acids proved toxic at 6.0 mM. None of the compounds evaluated exhibited mutagenicity, but each of them significantly reduced genetic damage caused by DXR, proving antigenotoxic when tested on somatic cells of D. melanogaster. DOI: http://dx.doi.org/10.17807/orbital.v9i1.897

    The widespread use of pesticides in agriculture can lead to water contamination and cause adverse effects on non-target organisms. Brazil has been the world's top pesticide market consumer since 2008, with 381 approved pesticides for crop use. This study provides a comprehensive literature review on the occurrence of pesticide residues in Brazilian freshwaters. We searched for information in official agency records and peer-reviewed scientific literature. Risk quotients were calculated to assess the potential risk posed to aquatic life by the individual pesticides based on their levels of water contamination. Studies about the occurrence of pesticides in freshwaters in Brazil are scarce and concentrated in few sampling sites in 5 of the 27 states. Herbicides (21) accounted for the majority of the substances investigated, followed by fungicides (11), insecticides (10) and plant growth regulators (1). Insecticides are the class of major concern. Brazil would benefit from the implementation of a nationwide pesticide freshwater monitoring program to support preventive, remediation and enforcement actions.

    Full Text Available The antileishmanial and immunomodulatory effects of propolis collected in Botucatu, São Paulo State, Brazil, were evaluated in Leishmania (Viannia braziliensis experimental infection. The antileishmanial effect of propolis on promastigote forms was verified by reducing growth and by promoting morphologic alterations observed by scanning electron microscopy. In in vitro immunomodulatory assays, macrophages were pretreated with propolis and then infected with L. (V. braziliensis. In vivo, supernatants from liver cells and peritoneal exudate of BALB/c mice pretreated with propolis and infected with Leishmania (107/mL promastigotes were collected, and TNF-α and IL-12 were measured by ELISA. Macrophages incubated with propolis showed a significant increase in interiorization and further killing of parasites. An increased TNF-α production was seen in mice pretreated with propolis, whereas IL-12 was downregulated during the infection. In conclusion, Brazilian propolis showed a direct action on the parasite and displayed immunomodulatory effects on murine macrophages, even though the parasite has been reported to affect the activation pathways of the cell. The observed effects could be associated with the presence of phenolic compounds (flavonoids, aromatic acids, and benzopyranes, di- and triterpenes, and essential oils found in our propolis sample.

    Full Text Available This article aims to reflect on the territorial dimension has been addressed in the current Brazilian health policy. Provides an initial approximation of the theoretical discussion about the category territory and its implications for social policy. Then we analyze how this category was included in the principles and guidelines of the National Health System, deployed in key programs and normative instruments of health policy from 1990. It is concluded that: the territorial dimension was present from conception through SUS guideline regionalization of activities and services. In the main programs implemented in the 1990s, the territorial dimension had a character cutouts geographical and normative instruments gave centrality to the process of decentralization. However, from the 2000s, the regionalization strategy, pointing to the territorial perspective, gains greater significance. However, we still need to overcome the logic purely political-administrative and act so as to identify the real needs of the people, their potential, diversity and particularities, towards "used territory" referred to Milton Santos.

    The rôle of astronomy in the Brazilian cultural diversity -though little known world- has been enormous. Thus, the different forms of popular music and erudite, find musical compositions and lyrics inspired by the stars, the eclipses in rare phenomena such as the transit of Venus in front of the sun in 1882, the appearance of Halley's Comet in 1910, in the Big Bang theory. Even in the carnival parades of the blocks at the beginning of the century astronomy was present. More recently, the parade of 1997, the samba school Unidos do Viradouro, under the direction of Joãozinho Trinta, offered a new picture of the first moments of the creation of the universe to join in the white and dark in the components of their school, the idea of matter and anti-matter that reigned in the early moments of the creation of the universe in an explosion of joy. Examples in classical music include Dawn of Carlos Gomes and Carta Celeste by Almeida Prado. Unlike The Planets by Gustav Holst -who between 1914 and 1916 composed a symphonical tribute to the solar system based on astrology- Almeida Prado composed a symphony that is not limited to the world of planets, penetrating the deep cosmos of galaxies.

    2010-07-01

    The first prototype of a hybrid electric fuel cell bus developed with Brazilian technology is unveiled. It is a 12 m urban-type, low-floor, air-conditioned bus that possesses three doors, air suspension, 29 seats and reversible wheelchair site. The bus body was built based on a double-deck type monoblock vehicle that is able to sustain important load on its roof. This allowed positioning of the type 3 hydrogen tanks and the low weight traction batteries on the roof of the vehicles without dynamic stabilization problems. A novel hybrid energy configuration was designed in such a way that the low-power (77 kWe) fuel cell works on steady-state operation mode, not responding directly to the traction motor load demand. The rate of kinetic energy regeneration upon breaking was optimized by the use of an electric hybrid system with predominance of batteries and also by utilizing supercapacitors. The electric-electronic devices and the security control softwares for the auxiliary and traction systems were developed in-house. The innovative hybrid-electric traction system configuration led to the possibility to decrease the fuel cell power, with positive impact on weight and system volume reduction, as well as to significantly decrease the hydrogen consumption.

    The purpose of this study was to evaluate the body composition, dietary intake, use of nutritional supplements, and biochemical status of 8 Brazilian male elite swimmers, aged 18-21 years, participants at a national swimming competition. Data from the athletes were obtained through a 4-day food record, a fasting blood sample, and anthropometric measurements. The anthropometric results showed that body composition was compatible with sport category. The dietary assessment showed an adequate ingestion of calories, vitamins, and mineral, with the exception of calcium, for which only half of the sample reached the recommendation. The results also indicated low carbohydrate and high protein and cholesterol intakes. Of the swimmers, 62.5% and 25% consumed synthetic aminoacids and antioxidants supplements, respectively. The biochemical indices of the nutritional status were within normal limits in all swimmers, with the exception of creatine-kinase, which was above the recommended level, indicating muscle degradation probably due to poor carbohydrate intake. In conclusion, the results suggest the importance of nutritional education to promote a balanced intake, provide all nutrients in optimal amounts, inhibit unnecessary ingestion of nutritional supplements, maintain ideal performance, and improve the swimmers' health status.

    Full Text Available Abstract Professional dental auxiliaries emerged in the early 20th century in the United States of America and quickly spread to Europe and other regions of the world. In Brazil, however, oral health technicians (OHTs, who occupy a similar role as dental hygienists, had a long journey before the occupation achieved legal recognition: Brazilian Law 11.889, which regulates this occupation in the country, was only enacted in 2008. The aim of this paper is to review the literature on the professionalization of OHTs, highlighting the triggering, limiting and conflicting aspects that exerted an influence on the historical progress of these professionals in Brazil. We have tested Abbott’s and Larson’s theory on professionalization, against the history of OHTs. A number of different dental corporative interests exerted an influence over professionalization, especially in discussions regarding the permissible activities of these professionals in the oral cavity of patients. With primary health care advances in Brazil, the importance of these professionals has once again come to the forefront. This seems to be a key point in the consolidation of OHTs in the area of human resources for health in Brazil.

  10. DISPOSITION EFFECT AMONG BRAZILIAN EQUITY FUND MANAGERS

    Full Text Available The disposition effect predicts that investors tend to sell winning stocks too soon and ride losing stocks too long. Despite the wide range of research evidence about this issue, the reasons that lead investors to act this way are still subject to much controversy between rational and behavioral explanations. In this article, the main goal was to test two competing behavioral motivations to justify the disposition effect: prospect theory and mean reversion bias. To achieve it, an analysis of monthly transactions for a sample of 51 Brazilian equity funds from 2002 to 2008 was conducted and regression models with qualitative dependent variables were estimated in order to set the probability of a manager to realize a capital gain or loss as a function of the stock return. The results brought evidence that prospect theory seems to guide the decision-making process of the managers, but the hypothesis that the disposition effect is due to mean reversion bias could not be confirmed.

The objective of this study is to discuss the potential and perspectives of the Brazilian Database on Orofacial Clefts. Methods. From 2008 to 2010, clinical and familial information on 370 subjects was collected by geneticists in eight different services. Data was centrally processed using an international system for case classification and coding. Results. Cleft lip with cleft palate amounted to 198 (53.5%, cleft palate to 99 (26.8%, and cleft lip to 73 (19.7% cases. Parental consanguinity was present in 5.7% and familial history of cleft was present in 26.3% subjects. Rate of associated major plus minor defects was 48% and syndromic cases amounted to 25% of the samples. Conclusions. Overall results corroborate the literature. Adopted tools are user friendly and could be incorporated into routine patient care. The BDOC exemplifies a network for clinical and genetic research. The data may be useful to develop and improve personalized treatment, family planning, and healthcare policies. This experience should be of interest for geneticists, laboratory-based researchers, and clinicians entrusted with OC worldwide.

  14. Copepods and fishes in the Brazilian Amazon

    1998-06-01

    The Amazon basin comprises the largest river ecosystem in the world (7 million km 2) with annual high and low water peaks and a constant temperature near 29°C. Some 2000 fish species and 40 species of free-living copepods are known to occur in Amazonia. The free-living forms serve as food for most larval fishes and some adults, but they also transmit several parasites including representatives of the nematode family Camallanidae. About three dozen species of parasitic copepods have been described from the Brazilian Amazon. Females of Amazonian parasitic copepods are found on skin, gill filaments, gill rakers or within the nasal fossae. Parasitic copepods are found on fishes that are from a few millimeters long up to those over 2 m in length and they are usually quite host specific. All have body pigmentation in different patterns and colors (frequently blues, such as cerulean, cobalt, spectrum, smalt or campanula). It is suggested that the coloration serves to attract specific host fish. Copepods have evolved adaptations for attachment and feeding, especially in the second antennae and endopods. Examples of progenesis, phoresis and commensalism are shown. Some species produce pathology such as a tourniquet effect, hyperplasia, blood loss and anemia, and can kill fishes by limiting their respiration.

    This article describes the configuration of the scientific field in Brazil, characterizing the scientific communities in every major area of knowledge in terms of installed capacity, ability to train new researchers, and capacity for academic production. Empirical data from several sources of information are used to characterize the different communities. Articulating the theoretical contributions of Pierre Bourdieu, Ludwik Fleck, and Thomas Kuhn, the following types of capital are analyzed for each community: social capital (scientific prestige), symbolic capital (dominant paradigm), political capital (leadership in S & T policy), and economic capital (resources). Scientific prestige is analyzed by taking into account the volume of production, activity index, citations, and other indicators. To characterize symbolic capital, the dominant paradigms that distinguish the natural sciences, the humanities, applied sciences, and technology development are analyzed theoretically. Political capital is measured by presidency in one of the main agencies in the S & T national system, and research resources and fellowships define the economic capital. The article discusses the composition of these different types of capital and their correspondence to structural capacities in various communities with the aim of describing the configuration of the Brazilian scientific field.

    Due to their geographical mobility and long periods of separation from intimate partners, migrant workers are at increased risk for a variety of sexually transmitted infections (STIs) including HIV/AIDS. This study sought to investigate patterns in HIV/AIDS related knowledge, attitudes and sexual behaviour in migrant workers in Croatia. In 2003, 566 male migrant workers were recruited during regular required medical examinations and surveyed at seven locations throughout the country. Each participant was asked to complete a self-administered KABP (sexual knowledge, attitudes, beliefs and practices) questionnaire. The average age of respondents was 38.2 years and the majority worked as seafarers (77.3%) and construction workers (20.5%). Only 18.5% of respondents were able to correctly answer all 13 questions assessing knowledge of HIV/AIDS. Seafarers reported higher levels of knowledge than did construction workers. The average respondent reported having had two sexual partners in the last 12 months, with slightly over half of the respondents (55.3%) reporting condom use at their last intercourse with a casual partner. One fifth of the respondents (20.3%) who reported having had intercourse with a sex worker during the last year reported not using condoms at last intercourse. The number of sexual partners was correlated with age, marital status, faith in God, and personal HIV risk assessment. Attitudes toward condom use, co-workers' HIV/AIDS concerns and the duration of migrant status (within the last two years) were shown to be significant correlates of condom use at last intercourse with a casual partner. The effect of HIV/AIDS related knowledge on analyzed behaviors did not reach statistical significance. Inadequate patterns of migrant workers' condom use, gaps in knowledge about HIV transmission and modes of protection, as well as widespread ignorance regarding available anonymous HIV testing found by this study suggest a critical need for expert intervention to

    Objective To evaluate whether there is any preference for citing journals from other countries to the detriment of Brazilian journals, in three Brazilian orthopedics journals. Methods All the references of articles published in 2011 by the journals Acta Ortopédica Brasileira, Coluna/Columna and Revista Brasileira de Ortopedia were evaluated to as certain how many of these came from Brazilian journals and how many from foreign journals. Results 3813 references distributed among 187 articles were analyzed. Out of this total, 306 (8.02%) were from Brazilian journals. There was no difference between the three journals analyzed. There were 76 articles (40.64%) without any citations of articles in Brazilian journals and only two articles (1%) cited more Brazilian articles than articles published elsewhere. Conclusion There is a need for Brazilian researchers to cite articles from Brazilian journals more often. PMID:26229879

    2012-01-01

    Full Text Available The purpose of this study is to analyze the process of internationalization of Brazilian firms, including the motivations for the internationalization, the modes of entry and the difficulties faced during this process. This research is relevant due to the importance of international management for Brazilian firms at the current global scenario. Firstly, it was developed a theoretical basis and, afterwards, an empirical qualitative and exploratory research was carried out. The data were collected from in depth interviews with the representatives of ten Brazilian franchisors that became international, which are associated to the Brazilian Association of Franchising (ABF, who gave support to the research. The analytical procedure adopted was the content analysis. Franchising was chosen because Brazil is one of the most developed countries in this field and franchising is recognized as an important booster of the globalization process. The interviews were conducted with either the owner of the firm or the marketing or international executive officers. The results of the empirical research show that, although Brazilian firms are late movers, the firms analyzed do not seem handicapped in terms of managerial capacity or technological competences. It is clear, nevertheless, that they are late movers because they have a huge internal market to explore. Adopting a global vision is very important, even if they prefer a gradual approach towards internationalization.

We focus on the 88 responding Brazilian private firms which are not majority owned by the state or a foreign company. We identify areas where Brazilian corporate governance is relatively strong and weak. Board independence is an area of weakness: The boards of most Brazilian private firms are comprised entirely or almost entirely of insiders or representatives of the controlling family or group. Many firms have zero independent directors. At the same time, minority shareholders have legal rights to representation on the boards of many firms, and this representation is reasonably common. Financial disclosure lags behind world standards. Only a minority of firms provide a statement of cash flows or consolidated financial statements. However, many provide English language financial statements, and an English language version of their website. Audit committees are uncommon, but many Brazilian firms use an alternate approach to ensuring financial statement accuracy – establishing a fiscal board. A minority of firms provide takeout rights to minority shareholders on a sale of control. Controlling shareholders often use shareholders agreements to ensure control.

    Full Text Available This paper presents an economic assessment of Brazilian agribusiness and its relationship with other economic sectors. It was found that, in 2011, agribusiness had a share of 18.45% (basic prices and 19.77% (market prices of Brazilian GDP. The tax burden of agribusiness (20.68% was higher than that of other sectors (13.59%, despite agribusiness being a major contributor to the generation of foreign exchange, employment, and essential products, such as food. Brazilian agribusiness is a major employer, responsible for 29.39% of national employment. However, its average income is lower than in the other sectors of the Brazilian economy. Finally, agribusiness was found to be the biggest generator of foreign exchange, with a positive balance of trade. It was possible to conclude that agribusiness forms a strong link between agriculture and livestock, industry, and services in other economic sectors. For this reason, it can be said that the development of agribusiness is highly relevant to the process of Brazilian economic development and is therefore important to the progress of economic policies.

    Full Text Available Propolis is a complex honeybee product with resinous aspect, containing plant exudates and beeswax. Their color, texture, and chemical composition vary, depending on the location of the hives and local flora. The most studied Brazilian propolis is the green (alecrim-do-campo type, which contains mainly prenylated phenylpropanoids and caffeoylquinic acids. Other types of propolis are produced in Brazil, some with red color, others brown, grey, or black. The aim of the present work was to determine the chemical profiles of alcohol and chloroform extracts of eight samples of propolis, corresponding to six Brazilian regions. Methanol and chloroform extracts were obtained and analyzed by HPLC/DAD/ESI/MS and GC/MS. Two chemical profiles were recognized among the samples analyzed: (1 black Brazilian propolis, characterized chiefly by flavanones and glycosyl flavones, stemming from Picos (Piauí state and Pirenópolis (Goiás state; (2 green Brazilian propolis, characterized by prenylated phenylpropanoids and caffeoylquinic acids, stemming from Cabo Verde (Bahia state, Lavras and Mira Bela (Minas Gerais state, Pariquera-Açu and Bauru (São Paulo state, and Ponta Grossa (Paraná state. The present work represents the first report of prenylated flavonoids in Brazilian propolis and schaftoside (apigenin-8-C-glucosyl-6-C-arabinose in green propolis.

    Full Text Available OBJECTIVES: To identify the most cited articles in general surgery published by Brazilian authors. INTRODUCTION: There are several ways for the international community to recognize the quality of a scientific article. Although controversial, the most widely used and reliable methodology to identify the importance of an article is citation analysis. METHODS: A search using the Institute for Scientific Information citation database (Science Citation Index Expanded was performed to identify highly cited Brazilian papers published in twenty-six highly cited general surgery journals, selected based on their elevated impact factors, from 1970 to 2009. Further analysis was done on the 65 most-cited papers. RESULTS: We identified 1,713 Brazilian articles, from which nine papers emerged as classics (more than 100 citations received. For the Brazilian contributions, a total increase of about 21-fold was evident between 1970 and 2009. Although several topics were covered, articles covering trauma, oncology and organ transplantation were the most cited. The majority of classic studies were done with international cooperation. CONCLUSIONS: This study identified the most influential Brazilian articles published in internationally renowned general surgery journals.

    Full Text Available ABSTRACTAfter more than twenty years of low housing construction output, the housing policy recovered its momentum in the country with the ascent of the Partido dos Trabalhadores (Workers' Party, PT to the seat of the federal government. This article demonstrates - through the analysis of documents, interviews and research conducted with businessmen - that the impetus of such a state policy is a part of the PT electoral strategy, which is based on economic growth and the expansion of social programs. The research analyses the dovetailing of interests between the Lula (the Brazilian President from 2003 to 2010 administration and the civil construction business - the latter concerned with expanding its business, and the former with increasing the supply of jobs and the level of economic activity. This process culminated in the launching of the largest social housing program to be implemented in the country. Minha Casa, Minha Vida (My House, My Life, is a project in whose planning building companies played a key role, performing feasibility studies and carrying out social housing projects.

    2015-06-01

    Full Text Available From sustainability perspective, the supply chain management strategy can use different indicators related to Triple Bottom Line to improve its practices. Some studies in the topic have focused only environmental issues; however in some cases the social issues should be considered as a core of the sustainable strategies. Considering this view, the paper aims to highlight the relevance of social issues in the Brazilian context toward sustainable supply chain. Therefore, a theoretical essay was conducted using the literature about sustainable supply chain in relation to the Brazilian perspective to understand how it is possible to use new approaches for a more emphasis on social issues. The discussions indicates that to re-conceptualize the social relations in supply chains, it's necessary to use corporate social responsibility and social capital approaches to create a better discussion about sustainable supply chain. The proposal starts a discussion in the Brazilian context to stimulate new scholars to study this topic.

  20. Systematic risk variations (beta convertible debenture brazilian companies

    2010-01-01

    Full Text Available purpose of this article is to analyze the impact of issuing convertible debentures on the systematic risk of Brazilian companies. Some applied researches in the U.S. capital market (STEIN, 1992; LEWIS et al, 2002; RAI, 2005 indicate that convertible debentures may be used as an alternative financing source when adverse selection problem makes stock issuing unattractive financing source. The analysis of Brazilian companies that issued convertible debentures recorded in the period from 1998 to 2006 and that presented liquidity on the market indicated that variation in beta, on average, is positive. These results are coherent with the signaling hypothesis and with the absence of convertible debenture issuing in 2005 and 2006 on the Brazilian market. They also may be related to the precarious financial situation of issuing companies, observed by the analysis of some financial indicators in year of issue and in two pre- e post-issuing years.

    Full Text Available Brazil was the first developing country to provide free, universal access to antiretroviral treatment for AIDS patients. The Brazilian experience thus provides the first evidence regarding the impact of such treatment on the survival of perinatally acquired AIDS cases in the developing world. MATERIAL AND METHODS: This retrospective cohort study used medical record reviews to examine characteristics and trends in the survival of a representative sample of 914 perinatally acquired AIDS cases in 10 Brazilian cities diagnosed between 1983 and 1998. RESULTS: Survival time increased steadily and substantially. Whereas half of the children died within 20 months of diagnosis at the beginning of the epidemic, 75% of children diagnosed in 1997 and 1998 were still alive after four years of follow-up. CONCLUSIONS: Advances in management and treatment have made a great difference in the survival of Brazilian children with AIDS. These results argue strongly for making such treatment available to children in the entire developing world.

    Phase II of the Centrifuge Workers Study was a follow-up to the Phase I efforts. The Phase I results had indicated a higher risk than expected among centrifuge workers for developing bladder cancer when compared with the risk in the general population for developing this same type of cancer. However, no specific agent could be identified as the causative agent for these bladder cancers. As the Phase II Report states, Phase I had been limited to workers who had the greatest potential for exposure to substances used in the centrifuge process. Phase II was designed to expand the survey to evaluate the health of all employees who had ever worked in Centrifuge Program Departments 1330-1339 but who had not been interviewed in Phase I. Employees in analytical laboratories and maintenance departments who provided support services for the Centrifuge Program were also included in Phase II. In December 1989, the Oak Ridge Associated Universities (ORAU), now known as Oak Ridge Institute for Science and Education (ORISE), was contracted to conduct a follow-up study (Phase II). Phase H of the Centrifuge Workers Study expanded the survey to include all former centrifuge workers who were not included in Phase I. ORISE was chosen because they had performed the Phase I tasks and summarized the corresponding survey data therefrom.

    Full Text Available Background: Long term occupational exposure to cotton dust is associated with respiratory symptoms and loss of pulmonary function. Aim: This study was conducted to explore respiratory symptoms, pulmonary function tests and chest radiography of workers, and to evaluate the findings of high resolution computed tomographyand its correlation with pulmonary function tests (PFT. Material and Methods: The study was conducted on 100 cotton workers as exposed group and 100 unexposed subjects. Smokers were excluded from the study. All workers were interviewed and examined by the pulmonologist. PFT and chest radiography were conducted for all subjects. HRCT was performed for those with abnormal PFT or chest radiography. Results: A total of 51% and 31% of the cotton textile workers had one or more respiratory symptoms and respiratory signs respectively. 28% of subjects in the exposed group and 5% of subjects in unexposed group had obstructive pattern. Bronchia wall thickening and air trapping were the most frequent chest radiography and HRCT abnormalities respectively. There was a significant correlation between HRCT and the results of PFT. Conclusion: We conclude that long term exposure to cotton dust is associated with obstructive disease that increase with duration of exposure (history of working years, also use of HRCT as a sensitive tool in the assessment of pathologic changes and it's correlation with PFT, confirms the expected pathophysiology of airway obstruction in cotton workers.

    Full Text Available Abstract Background From animal studies it is known that currently used pesticides can disturb thyroid function. Methods In the present study we investigated the thyroid function in 122 Danish greenhouse workers, to evaluate if greenhouse workers classified as highly exposed to pesticides experiences altered thyroid levels compared to greenhouse workers with lower exposure. Serum samples from the greenhouse workers were sampled both in the spring and the fall to evaluate if differences in pesticide use between seasons resulted in altered thyroid hormone levels. Results We found a moderate reduction of free thyroxine (FT4 (10–16% among the persons working in greenhouses with a high spraying load both in samples collected in the spring and the fall, but none of the other measured thyroid hormones differed significantly between exposure groups in the cross-sectional comparisons. However, in longitudinal analysis of the individual thyroid hormone level between the spring and the fall, more pronounced differences where found with on average 32% higher thyroid stimulating hormone (TSH level in the spring compared to the fall and at the same time a 5–9% lower total triiodthyroxin (TT3, free triiodthyroxine (FT3 and FT4. The difference between seasons was not consistently more pronounced in the group classified as high exposure compared to the low exposure groups. Conclusion The present study indicates that pesticide exposure among Danish greenhouse workers results in only minor disturbances of thyroid hormone levels.

    To evaluate the health effects of occupational phosphine exposure, 22 workers engaged in fumigation of stored grains were subjected to a clinical and environmental study. These workers were used to placing aluminum phosphide tablets on the stacks of grains and covering it with a gas-proof plastic cover. The mean age of the workers was 48 years (range 24-60) and mean duration of exposure 11.1 years (range 0.5-29). After fumigation they reported minor symptoms, which included cough (18.2%), dyspnoea (31.8%), tightness around the chest (27.3%), headache (31.8%), giddiness, numbness and lethargy (13.6% each), anorexia and epigastric pain (18.2% each). The abnormal physical signs included bilateral diffuse rhonchi and absent ankle reflex each occurring in one worker. Motor nerve conduction velocity of median and peroneal nerves, and sensory conduction velocity of median and sural nerves were normal. Phosphine concentration in the work environment ranged from 0.17 to 2.11 ppm. Occupational phosphine exposure in the workers was associated with mild to moderate symptoms, which were transient. However, to assess the chronic effects, long-term follow-up is recommended.

    Following previous work carried out in an Italian factory producing carbon electrodes and evaluating the occupational mutagenic-carcinogenic hazards, the authors studied the presence of mutagen metabolites in the urine of workers in the same factory who were exposed to petroleum coke and pitch and in the urine of a control group of unexposed workers. The urine samples were concentrated by absorption on XAD-2 columns and were tested using the Salmonella/microsome assay (strain TA98, TA100, TA1535, TA1538) with and without the addition of beta-glucuronidase and metabolizing system. The collection of urine samples was carried out twice, with an interval of 2 months; 'before working time', 'after working time', and also during Sunday. The results showed that urine samples collected 'before' occupational exposure (upon waking) or on Sunday revealed no mutagenic activity in either worker groups and that the urine samples collected after or during occupational exposure revealed high mutagenic activity in the exposed workers, with a statistically significant difference between the mean of the revertants/plate values for exposed and unexposed workers. On the basis of the previous and the present research, the authors suggest that application of the Salmonella/microsome test to work environments could offer useful and suitable tool for evaluating the health hazards due to mutagenic/carcinogenic substances from occupational exposure.

    Elections, specially in countries such as Brazil, with an electorate of the order of 100 million people, yield large-scale data-sets embodying valuable information on the dynamics through which individuals influence each other and make choices. In this work we perform an extensive analysis of data sets available for Brazilian proportional elections of legislators and city councilors throughout the period 1970-2014, which embraces two distinct political regimes: a military regime followed by a democratic one. We perform a comparative analysis of elections for legislative positions, in different states and years, through the distribution p(v) of the number of candidates receiving v votes. We show the impact of the different political regimes on the vote distributions. Although p(v) has a common shape, with a scaling behavior, quantitative details change over time and from one electorate to another. In order to interpret the observed features, we propose a multi-species model consisting in a system of nonlinear differential equations, with values of the parameters that reflect the heterogeneity of candidates. In its simplest setting, the model can not explain the cutoff, formed by the most voted candidates, whose success is determined mainly by their peculiar, intrinsic characteristics, such as previous publicity. However, the modeling allows to interpret the scaling of p(v), yielding a predictor of the degree of feedback in the interactions of the electorate. Knowledge of the feedback is relevant beyond the context of elections, since a similar interactivity may occur for other social contagion processes in the same population.

    An increasing volume of publications has addressed the role of tectonics in inland areas of northern Brazil during the Neogene and Quaternary, despite its location in a passive margin. Hence, northern South America plate in this time interval might have not been as passive as usually regarded. This proposal needs further support, particularly including field data. In this work, we applied an integrated approach to reveal tectonic structures in Miocene and late Quaternary strata in a coastal area of the Amazonas lowland. The investigation, undertaken in Marajó Island, mouth of the Amazonas River, consisted of shallow sub-surface geophysical data including vertical electric sounding and ground penetrating radar. These methods were combined with morphostructural analysis and sedimentological/stratigraphic data from shallow cores and a few outcrops. The results revealed two stratigraphic units, a lower one with Miocene age, and an upper one of Late Pleistocene-Holocene age. An abundance of faults and folds were recorded in the Miocene deposits and, to a minor extent, in overlying Late Pleistocene-Holocene strata. In addition to characterize these structures, we discuss their origin, considering three potential mechanisms: Andean tectonics, gravity tectonics related to sediment loading in the Amazon Fan, and rifting at the continental margin. Amongst these hypotheses, the most likely is that the faults and folds recorded in Marajó Island reflect tectonics associated with the history of continental rifting that gave rise to the South Atlantic Ocean. This study supports sediment deposition influenced by transpression and transtension associated with strike-slip divergence along the northern Equatorial Brazilian margin in the Miocene and Late Pleistocene-Holocene. This work records tectonic evidence only for the uppermost few ten of meters of this sedimentary succession. However, available geological data indicate a thickness of up to 6 km, which is remarkably thick for

    Full Text Available INTRODUCTION: aerobic fitness is considered one of the most important components of health-related physical fitness, with low levels related to increased risk of premature death from all causes, especially cardiovascular diseases. OBJECTIVE: to identify the characteristics of adolescents at higher risk of low levels of aerobic fitness. METHODS: the study included 696 adolescents 15-17 years of age enrolled in public high schools of Florianópolis, southern Brazil. This cross-sectional epidemiological study was conducted in Florianópolis, Santa Catarina, Brazil. Aerobic fitness was measured using the modified Canadian Aerobic Fitness Test mCAFT. Sociodemographic gender, age, school grade, paternal and maternal schooling, socioeconomic status, and anthropometric variables body weight, height, triceps and subscapular skinfold thickness, sexual maturation, physical activity, sedentary behavior, and eating habits were collected. RESULTS: it was found that 31.5% of adolescents had low aerobic fitness levels, being higher in boys 49.2% compared to girls 20.6%. Moreover, girls with sedentary behavior, overweight and high body fat percentage were the groups most likely to have inadequate aerobic fitness. In males, the groups most likely to have inadequate aerobic fitness were those whose parents studied more than eight years, those with low levels of physical activity, and those with inadequate nutrition and excessive body fat. CONCLUSION: low aerobic fitness levels were present in one third of adolescents and was more prevalent in boys. Lifestyle changes, including replacement of sedentary behaviors by physical and sport activities , may assist in improving the aerobic fitness of Brazilian adolescents.

    Full Text Available This paper used a bibliometric research to compare and draw an overview of scientific production on forensic Accounting area, published in Brazilian journals in the period between 2005 and 2014 regarding the number of publications, characteristics of the authors, published topics, methodologies and its subclasses and and journals that publish in the area. It was collected and analyzed 48 articles the information as variation of year publication, subjects treated by, authors and their characteristics, Qualis classification, methodology, methodological nature applied, description of the empirical method and journals that have published articles in the area. Descriptive statistics were used to analyze the data. As a result it was found that the main subjects considered are related to the "work of the expert accountant", "expert opinion" and expertise within the context of judicial proceedings. Regarding the authors the vast majority produce only one article in the area over the 10 years examined, and these authors, 64,58% were male. The Qualis extract of the articles is located between C and B1, indicating that the publications fail to achieve high standards of academic quality. On the methodology it was found that 91.67% are empirical research, of these 78% ranked in quantitative or qualitative and 83% are publications opting for descriptive techniques. Regarding the journals, it was found that 50% have only one publication on "forensic accounting", indicating that it is not repeated exposure, as the number of publications ranging from two to five in the other 50% of journals. It is concluded that scientific research in forensic accounting area are still relatively embryonic, lacking certain softening related to the subjects, number of publications and quality of intellectual production.

    Objective: To identify the types and causes of eye injury in industrial workers. Methods: A cross sectional study of the pattern of ocular injuries in Delta state of Nigeria was carried out over 3 months. Five hundred workers were interviewed and examined using the Snellen's chart, pen-torch, direct ophthalmoscope, magnifying loupe and the Perkin's hand-held applanation tonometer. Results: All the 500 workers were males. One hundred and twenty-three workers (24.6%) reported a history of ocular injury at work. The most common causative agents were sand dust, 53 workers (25.1%); cake dust, 27 workers (12.8%) and chemicals, 32 workers (15.1%). The main types of ocular injury were corneal/ conjunctival foreign bodies, 79 workers (64.2%); burns, 35 workers (28.5%) and blunt injury, 9 workers (7.3%). Only 36 (7.2%) workers used protective eye devices at work. Thirteen workers (2.6%) developed monocular blindness from ocular injury. Conclusion: Ocular injury at work is common and few workers wear protective devices at work in industries in Delta state, Nigeria. Industrial workers should have regular eye services and wear eye safety devices at work.

  18. Heuristic for Task-Worker Assignment with Varying Learning Slopes

    Full Text Available Fashion industry has variety products, so the multi-skilled workers are required to improve flexibility in production and assignment. Generally the supervisor will assign task to the workers based on skill and skill levels of worker. Since in fashion industry new product styles are launched more frequently and the order size tends to be smaller, the workers always learn when the raw material and the production process changes. Consequently they require less time to produce the succeeding units of a task based on their learning ability. Since the workers have both experience and inexperience workers, so each worker has different skill level and learning ability. Consequently, the assignment which assumed constant skill level is not proper to use. This paper proposes a task-worker assignment considering worker skill levels and learning abilities. Processing time of each worker changes along production period due to a worker learning ability. We focus on a task-worker assignment in a fashion industry where tasks are ordered in series; the number of tasks is greater than the number of workers. Therefore, workers can perform multiple assignments followed the precedence restriction as an assembly line balancing problem. The problem is formulated in an integer linear programming model with objective to minimize makespan. A heuristic is proposed to determine the lower bound (LB and the upper bound (UB of the problem and the best assignment is determined. The performance of the heuristic method is tested by comparing quality of solution and computational time to optimal solutions.

    By means of scientometric indicators, this study investigated the characteristics of scientific production and research collaboration involving zebrafish (Danio rerio) in Brazilian Science indexed by the Web of Science (WoS). Citation data were collected from the WoS and data regarding Impact Factor (IF) were gathered from journals in the Journal Citation Reports. Collaboration was evaluated according to coauthorship data, creating representative nets with VOSviewer. Zebrafish has attained remarkable importance as an experimental model organism in recent years and an increase in scientific production with zebrafish is observed in Brazil and around the world. The citation impact of the worldwide scientific production is superior when compared to the Brazilian scientific production. However, the citation impact of the Brazilian scientific production is consistently increasing. Brazil does not follow the international trends with regard to publication research fields. The state of Rio Grande do Sul has the greatest number of articles and the institution with the largest number of publications is Pontifícia Universidade Católica do Rio Grande do Sul. Journals' average IF is higher in Brazilian publications with international coauthorship, and around 90% of articles are collaborative. The Brazilian institutions presenting the greatest number of collaborations are Pontifícia Universidade Católica do Rio Grande do Sul, Universidade Federal do Rio Grande do Sul, Fundação Universidade Federal de Rio Grande, and Universidade de São Paulo. These data indicate that Brazilian research using zebrafish presents a growth in terms of number of publications, citation impact, and collaborative work.

    In this article, we present the Brazilian Portuguese Lexicon, a new word-based corpus for psycholinguistic and computational linguistic research in Brazilian Portuguese. We describe the corpus development, the specific characteristics on the internet site and database for user access. We also perform distributional analyses of the corpus and comparisons to other current databases. Our main objective was to provide a large, reliable, and useful word-based corpus with a dynamic, easy-to-use, and intuitive interface with free internet access for word and word-criteria searches. We used the Núcleo Interinstitucional de Linguística Computacional's corpus as the basic data source and developed the Brazilian Portuguese Lexicon by deriving and adding metalinguistic and psycholinguistic information about Brazilian Portuguese words. We obtained a final corpus with more than 30 million word tokens, 215 thousand word types and 25 categories of information about each word. This corpus was made available on the internet via a free-access site with two search engines: a simple search and a complex search. The simple engine basically searches for a list of words, while the complex engine accepts all types of criteria in the corpus categories. The output result presents all entries found in the corpus with the criteria specified in the input search and can be downloaded as a.csv file. We created a module in the results that delivers basic statistics about each search. The Brazilian Portuguese Lexicon also provides a pseudoword engine and specific tools for linguistic and statistical analysis. Therefore, the Brazilian Portuguese Lexicon is a convenient instrument for stimulus search, selection, control, and manipulation in psycholinguistic experiments, as also it is a powerful database for computational linguistics research and language modeling related to lexicon distribution, functioning, and behavior.

    Full Text Available This article compares between the Master and Slave dialectic and the Brazilian Landless Workers Movement (MST. This movement presents new elements that are beyond the traditional analysis criteria in such fields as religion, health and education. According to Tilman Evers popular movements in Latin America can be divided into three periods. In the first one, from 60’s to 70’s, the movements are identified with terrorist actions. In the second period, popular movements become closer to human rights and are accepted by public opinion. Considering MST as a new social movement, we can see its originality in the treatment of religion, health and education policies. Power relationships can no longer be analyzed in terms of traditional polar oppositions and demand new formulations.

    This paper discusses the chronology of prehistoric settlements of the central-south Brazilian coast. A charcoal sample from a coastal shell mound of Rio de Janeiro State was dated by {sup 14} C-AMS to 7, 860+- 80 years B P as part of an interdisciplinary project between physicists and archaeologists. This is an unexpected result that reinforces two similar previous early dates for the same region, which were questioned by Brazilian archaeologists because they implied in pulling back by some two thousand years the antiquity consensually accepted for the settlement of that region.

    1984-08-01

    A five step investigation was carried out to gain a better understanding of the morbidity that accompanied the development of telangiectasia on aluminium workers and to find its cause. Fifty workers with multiple telangiectasia when matched with normal controls showed the same amount of illness except that evidence of ischaemia on the ECG was found in nine cases and one control. The cases did not show an excess of abnormal biochemical tests. The basic histopathological lesion affected the surrounding tissue rather than the vessels themselves. Working in the current environment and wearing masks seems to protect young workers from developing the lesions. The Soderberg and not the prebake process was associated with the lesions; the causative agent is probably a gas that contains both hydrocarbons and fluoride components emitted from the electrolytic reactors.

  6. Social Workers as Civic-Minded Professionals

    2014-01-01

    Full Text Available This study examined civic-mindedness among a sample of social work educators, community practitioners and new graduates. Using a web-based survey, researchers administered Hatcher’s (2008 Civic-Minded Professional scale. Results indicated that traditional and field faculty were more civic-minded than new graduates and other practitioners. Social work educators who focused on raising civic awareness in courses were more civic-minded than colleagues. New graduates who had participated in club service events were more civic-minded; however, there was no significant differences between groups based on number of community service courses completed. Social workers, whether faculty or not, who had participated in collaborative research were more civic-minded. The authors conclude that how social workers view their commitment to civic engagement has implications. Social workers need to be vigilant in our commitment to well-being in society. Intentional practices could be implemented to strengthen the partnership among groups.

    The results of health questionnaire interviews with 390 electrical power transmission and distribution workers, together with long term estimates of their exposure to 50 Hz electric fields, and short term measurements of the actual exposure for 287 of them are reported. Twenty eight workers received measurable exposures, averaging about 30 kVm-1h over the two week measurement period. Estimated exposure rates were considerably greater, but showed fair correlation with the measurements. Although the general level of health was higher than we have found in manual workers in other industries, there were significant differences in the health measures between different categories of job, different parts of the country, and in association with factors such as overtime, working alone, or frequently changing shift. After allowing for the effects of job and location, however, we found no significant correlations of health with either measured or estimated exposure to electric fields.

    The aim of this study was to investigate thiol/disulfide homeostasis in asphalt workers who are exposed to polycyclic aromatic hydrocarbons occupationally. The study was carried out in 34 nonsmoker asphalt workers. Additionally, 35 healthy nonsmoker volunteers were recruited as control group. Thiol and disulfide concentrations were determined using the novel automated measurement method. Levels of urinary 1-OH-pyrene were analyzed by liquid chromatography. Disulfide/thiol ratio was significantly higher in exposed group (p = .034). Also, a positive correlation was detected between disulfide/thiol ratio and 1-OH-pyrene values (r = .249, p = .036). Thiol/disulfide homeostasis was found to be disturbed in asphalt workers. The novel test used in this study may be useful for evaluating the oxidative status in polycyclic aromatic hydrocarbon (PAH) exposure.

    Mechanics are exposed to varied work stressors such as hot noisy environments, strenuous postures, improperly designed tools and machinery and poor psycho-social environments which may exert an influence on their health and safety. The study aimed to examine the occupational injury patterns and identify work stressors associated with injury amongst automobile mechanics. A descriptive ergonomic checklist and questionnaire on general health and psycho-social issues were administered to male workers (N=153). The relative risk factors and correlation statistics were used to identify the work stressors associated with occupational injury. 63% of the workers reported injuries. Cuts were the chief injuries being reported. Poor work environment, machinery and tool characteristics, suffering from poor health and psycho-social stressors were associated with injury occurrence amongst automobile repair workers.

    The lung function impairment is the most common respiratory problem in industrial plants and their vicinity. Therefore, the purpose was to study the affects of wood dust and its duration of exposure on lung function. This was a matched cross-sectional study of Spirometry in 46 non-smoking wood workers with age range 20 - 60 years, who worked without the benefit of wood dust control ventilation or respiratory protective devices. Pulmonary function test was performed by using an electronic Spirometer. Significant reduction was observed in the mean values of Forced Vital Capacity (FVC), Forced Expiratory Volume in one second (FEV1), and Maximum Voluntary Ventilation (MVV) in wood workers relative to their matched controls. This impairment was increased with the duration of exposure to wood industries. It is concluded that lung function in wood workers is impaired and stratification of results shows a dose-response effect of years of wood dust exposure on lung function.

    Full Text Available Background: Incinerator workers are not considered to have arsenic overexposure although they have the risk of overexposure to other heavy metals. Aim: To examine the relationship between arsenic burden and risk of occupational exposure in employees working at a municipal refuse incinerator by determining the concentrations of arsenic in the blood and urine. Settings and Design: The workers were divided into three groups based on their probability of contact with combustion-generated residues, namely Group 1: indirect contact, Group 2: direct contact and Group 3: no contact. Healthy age- and sex-matched residents living in the vicinity were enrolled as the control group. Materials and Methods: Heavy metal concentrations were measured by atomic absorption spectrophotometer. Downstream rivers and drinking water of the residents were examined for environmental arsenic pollution. A questionnaire survey concerning the contact history of arsenic was simultaneously conducted. Statistical analysis: Non-parametric tests, cross-tabulation and multinomial logistic regression. Results: This study recruited 122 incinerator workers. The urine and blood arsenic concentrations as well as incidences of overexposure were significantly higher in the workers than in control subjects. The workers who had indirect or no contact with combustion-generated residues had significantly higher blood arsenic level. Arsenic contact history could not explain the difference. Airborne and waterborne arsenic pollution were not detected. Conclusion: Incinerator workers run the risk of being exposed to arsenic pollution, especially those who have incomplete protection in the workplace even though they only have indirect or no contact with combustion-generated pollutants.

    Full Text Available Background and Design: We aimed to determine the frequency of latex allergy in our hospital and to to evaluate the clinical and demographical features of the cases.Materials and Methods: A detailed questionnaire was administered to healthcare workers by a physician. Skin prick test with latex and patch test with rubber chemicals and a piece of latex glove were performed for all healthcare workers. Latex-specific IgE was measured in serum.Results: The study sample consisted of 36 nurses, 14 doctors, and 50 healthcare workers. While 46 subjects had symptoms, 54 subjects had no symptoms. The relationship of clinical disease with working duration, exposure duration (hour/day, history of atopy, and drug/food allergies was statistically significant. Five nurses and 1 healthcare worker had positive skin prick test. Two of them had positive latex-specific IgE. Positive skin prick test statistically significantly correlated with occupation, working duration, exposure duration (hour/day and positive latex-specific IgE. Two nurses and 2 healthcare workers had positive latex-specific IgE. Two of them had positive skin prick test. Positive latexspecific IgE statistically significantly correlated with working duration, exposure duration, and positive skin prick test. Patch test with a piece of latex glove was negative in all subjects. Three healthcare workers had positive patch test with thiuram-mix, one of them had also positive patch test with mercaptobenzothiazole.Discussion: One of the risk factors for latex allergy is occupations involving frequent exposure to latex products. Latex allergy should be taken into consideration if type I hypersensitivity reactions occur in occupational groups at risk for anaphylactic reaction.

    Interruption of the spread of human immunodeficiency virus (HIV) across southeast Asian borders by legal and illegal migrant laborers is a major concern of the Association of Southeast Asian Nations (ASEAN). ASEAN intends to move immediately to implement regional projects focused on education, information sharing, and improved surveillance. HIV transmission from laborers from poorer countries in search of jobs in economically booming regions underscores the global nature of the AIDS problem. Malaysia, for example, has over 1 million illegal workers. Moreover, many legal guest workers who enter Malaysia with letters from a physician stating they are not HIV-infected have falsified documents.

  20. We, the others: construction of the exotic and consumption of brazilian fashion in France

    Directory of Open Access Journals (Sweden)

    Débora Krischke Leitão

    Full Text Available This article discusses the consumption of Brazilian products - especially fashion and clothing - in France as a way of consuming the exotic. Drawing on ten months of fieldwork in France, I engage data collected there with my experience from previous research carried out in Brazil. Firstly, this article discusses exoticism, a topic that invariably broaches a debate about identity and alterity. Then, some particularities of "consuming the other" in French discourses about Brazilian products are analyzed. Finally, I conclude that the construction of Brazilian fashion as exoticism is simultaneously situated in the French imaginary about the Brazilian other and in the very Brazilian production of garment fashion.

    Based on a Foucauldian framework, this article discusses the involvement of the Forum for Defence of the Sistema Único de Saúde in the fight against health care privatization. Community participation is a locus of experience that produces subjects implicated in the production of public health care. The locus of experience in this instance derives from the rejection of private elements that historically have been part of Brazilian public policies. It is an experience that produces workers and service users as agents able to defend the public system and endowed with instituting power.

    Full text: Coffee is one of the most popular and consumed beverages worldwide. Consumers can make the beverage from different types of coffee such as ground coffee, instant coffee or grinding roasted coffee beans. Each type of coffee leads to different characteristics in flavor and scent. The aim of this work is to perform an elemental analysis of ground coffee and roasted coffee beans. To that end, eight popular Brazilian ground coffee brands have been chosen to make a comparative study among brands. One of these brands was selected for a complete study of the beverage preparation process. This same brand offers packages of roasted coffee beans, which allowed the elemental comparison between ground coffee and roasted coffee beans. Roasted coffee beans were ground with a pestle and mortar. The beverage was prepared using a typical coffee pot. The spent and liquid coffees were submitted to a heat treatment and subsequently homogenized and pressed into pellets. The filters used in the coffee pot were analyzed as well. For micro-PIXE studies, coffee beans were cut in different parts for analysis. Samples of ground coffee and roasted coffee beans (grind) were analyzed by PIXE, while light elements like C, O and N were analyzed by RBS (Rutherford Backscattering Spectrometry). The roasted coffee beans were analyzed by micro-PIXE to check the elemental distribution in the beans. The elements found in powder coffee were Mg, AI, Si, P, S, CI, K, Ca, Ti, Mn, Fe, Cu, Zn and Rb. Potassium is the element with higher concentration, while Ti and Zn are trace elements. AI, Si and Ti showed the same concentration for all brands. Potassium and chlorine have high solubility, and about 80% of their concentration is transferred from the powder to the beverage during the infusion. Mg, P, CI, K, Mn, Fe, Zn and Rb showed significant variation between ground coffee and roasted coffee beans. The elemental maps show that potassium and phosphorus are correlated, and iron appears in particular

    Full Text Available ABSTRACT OBJECTIVE To estimate the prevalences of tobacco use, tobacco experimentation, and frequent smoking among Brazilian adolescents. METHODS We evaluated participants of the cross-sectional, nation-wide, school-based Study of Cardiovascular Risks in Adolescents (ERICA, which included 12- to 17-year-old adolescents from municipalities of over 100 thousand inhabitants. The study sample had a clustered, stratified design and was representative of the whole country, its geographical regions, and all 27 state capitals. The information was obtained with self-administered questionnaires. Tobacco experimentation was defined as having tried cigarettes at least once in life. Adolescents who had smoked on at least one day over the previous 30 days were considered current cigarette smokers. Having smoked cigarettes for at least seven consecutive days was an indicator for regular consumption of tobacco. Considering the complex sampling design, prevalences and 95% confidence intervals were estimated according to sociodemographic and socio-environmental characteristics. RESULTS We evaluated 74,589 adolescents. Among these, 18.5% (95%CI 17.7-19.4 had smoked at least once in life, 5.7% (95%CI 5.3-6.2 smoked at the time of the research, and 2.5% (95%CI 2.2-2.8 smoked often. Adolescents aged 15 to 17 years had higher prevalences for all indicators than those aged 12 to 14 years. The prevalences did not differ significantly between sexes. The highest prevalences were found in the South region and the lowest ones, in the Northeast region. Regardless of sex, the prevalences were found to be higher for adolescents who had had paid jobs, who lived with only one parent, and who reported having been in contact with smokers either inside or outside their homes. Female public school adolescents were found to smoke more than the ones from private schools. CONCLUSIONS Tobacco use among adolescents is still a challenge.

    2010-06-01

    Previous research shows that monolingual Japanese and Brazilian Portuguese listeners perceive illusory vowels (/u/ and /i/, respectively) within illegal sequences of consonants. Here, several populations of Japanese-Brazilian bilinguals are tested, using an explicit vowel identification task (experiment 1), and an implicit categorization and sequence recall task (experiment 2). Overall, second-generation immigrants, who first acquired Japanese at home and Brazilian during childhood (after age 4) showed a typical Brazilian pattern of result (and so did simultaneous bilinguals, who were exposed to both languages from birth on). In contrast, late bilinguals, who acquired their second language in adulthood, exhibited a pattern corresponding to their native language. In addition, an influence of the second language was observed in the explicit task of Exp. 1, but not in the implicit task used in Exp. 2, suggesting that second language experience affects mostly explicit or metalinguistic skills. These results are compared to other studies of phonological representations in adopted children or immigrants, and discussed in relation to the role of age of acquisition and sociolinguistic factors.

    Full Text Available This article provides an overview of human resource strategies employed by Brazilian companies in a polarized region of Latin America. Firstly, we highlighted the concerns of Brazilian managers in respect to the coming years, and to identify the current strategic approach of prominent companies in the Brazilian market. Secondly, we identified possible strategies for internationalization, particularly in the context of Latin America. The results of two surveys were used: one prospecting management trends by 2015 and another consisting of a sample of 541 companies that participate in a national survey in which HR managers answered a questionnaire. Among the results, it is noteworthy that the main issues of concern for Brazilian managers in the coming years. We found most the companies concerned with these challenges in the industries of information technology, iron and steel, and health services. Forty-nine of a total of 541 companies intend to internationalize, 17 of them towards Latin American. Their profile characterization allowed us to divide them into two groups: those focusing on the local needs of Latin American, and those looking to meet the expanding needs of Brazil or the country of their parent company.

    The use of natural compounds from biodiversity, as well as ethnobotanical knowledge, for the development of new drugs is the gate leading to support the conservation of natural resources in developing countries. Recent technological advances and the development of new methods are revolutionizing the screening of natural products and offer a unique opportunity to replace natural products as major source of drug leads. Over the past decades, the Brazilian government established a legislation aiming to grant patent protection in all technological fields. The Convention on Biological Diversity, an international agreement that recognizes the sovereign rights of States over their natural resources, and the Brazilian legislation (Decreto n degree 2186-12/01) set for legislative, administrative or policy measures regarding the share of research and product development benefits could be the key for progress in issues related to rational employment of the Brazilian biodiversity and economy, but are far from being effective. Based on literature review, this article provides a brief description of the Brazilian legislation policy regarding intellectual property and biodiversity access, places natural drug discovery in context, analyzes patent cases and highlights critical key issues responsible for the drawback of the whole process that has a direct impact on industrial and research development, nature protection and benefit share with our society.

    Full Text Available OBJECTIVE: This review of original reports on metabolic and infectious diseases that were recently published in Brazilian journals is designed to inform the readership of CLINICS about their content. METHODS: I conducted a search in PubMed for original research articles (clinical or basic research recently published (2008-2009 by Brazilian medical and biological periodicals. Papers on metabolic pathologies were retrieved by searching for appropriate keywords such as metabolic syndrome and obesity. Papers on infectious disease were obtained by entering 15 different keywords for the most commonly occurring pathologies. Review articles, editorials, letters to the editor, and case reports were manually excluded. Selected titles were then categorized into appropriate sub-categories. RESULTS: This search produced a total of 123 articles, which filtered down to 72 articles after eliminating editorials, review articles, letters to the Editor and case reports. Reviewed periodicals were Arquivos Brasileiros de Cardiologia, Arquivos Brasileiros de Endocrinologia e Metabologia, Brazilian Journal of Biological and Medical Research, Brazilian Journal of Infectious Diseases, Jornal de Pediatria, Jornal de Pneumologia, Revista da Associação Médica Brasileira, Revista da Escola de Enfermagem da Universidade de São Paulo, and São Paulo Medical Journal. The articles were then briefly summarized.
