Burnout syndrome, working conditions, and health: a reality among public high school teachers in Brazil

The objective of the study was to evaluate the occurrence of Burnout Syndrome in 100 teachers of six public high schools and its correlation with working conditions in a southeast city of Brazil. Characterization of the sample occurred after application of a socio-demographic questionnaire. Evaluation of the working conditions was done by means of an Ergonomic Working Analysis. The presence of Burnout Syndrome was evaluated by means of the Maslach Burnout Inventory. The sample presented the predominance of women, with an average age of 40.4 and the majority married with children. Roughly 50% had less than 10 years of service, and more than half of the teachers taught more than 18 classes per week. Hoarseness after work was principally reported among women, which required many days off for health treatment. Environmental conditions reflect inadequacy in relation to noise, light, humidity and temperature. Presence of pain in the upper limbs was especially high among women. Risk of musculoskeletal disorders in the upper limbs predominated as moderately important to significant. We also identified an average distance walked by teachers of 1.5 Km and an average of 4.2 Kg of school supplies carried between classes. The Burnout Syndrome presented a high score for depersonalization principally among men, but it has association with both sexes. Emotional exhaustion correlates with noise, depersonalization, and personal fulfillment, in addition to the high number of weekly lessons. It can be concluded that Burnout syndrome is present among teachers, principally in terms of depersonalization, deserving the attention of government officials and the schools, as well as the teachers themselves.     

Diagnostic tests for the distribution of random effects in multivariate mixed effects models

Abstract

Fourier methods are proposed for testing the distribution of random effects in classical and robust multivariate mixed effects models. The test statistics involve estimation of the characteristic function of random effects. Theoretical and computational issues are addressed while Monte Carlo results show that the new procedures compare favorably with other methods.     

Female Professional Work Opportunities: A Cross-National Study

While economic development has been associated with increased participation of females in the labor force, it remains problematic whether sexual equality within the labor force has also increased. This study examines the differentiation of structural variables, specifically economic and demographic variables, on female participation and sexual equality within a specific sector of the labor force: the professions. The units of analysis are primarily European countries with the inclusion of the United States, Canada, Australia and New Zealand. The findings indicate that those economic development factors (female higher education enrollment rate and professional demand) significantly related to the female professional participation rate are distinct from those structural factors (economic growth rate, working age male deficiency) affecting sexual equality within the professional sector.     

The one child certificate in Hebei province,China: Acceptance and consequence, 1979–1988

As part of its One Child Policy, China developed the one child certificate which offered numerous benefits to couples who had one child and promised to have no more. Using data from the Two-per-Thousand National Fertility Survey, this study describes the level of certificate acceptance in Hebei province from 1979 to 1988 and analyzes socioeconomic, cultural and early family formation factors affecting certificate acceptance as well as the role of certificate acceptance on transition to second parity. During the past decade, the level of initial certificate acceptance was 22.6 percent. This estimate is much lower than earlier published rates because it utilizes the concept of women at risk. Public resistance to the One Child Policy is evident in declining acceptance from 26.0 percent during the first five years of the policy to 11.3 percent during the 1984–1988 period. Women's response to the certificate has been influenced by the woman's status as reflected in education and occupation as well as cultural traditions, particularly son preference. The one child certificate, however, independently depresses subsequent fertility. This research indicates that efforts to understand fertility decline in China must simultaneously acknowledge the role of government family planning programs as well as socioeconomic and cultural factors.Revision of paper presented at the American Sociological Association Meeting, 1990.     

CO-tucker: a new method for the simultaneous analysis of a sequence of paired tables

Relationships between species and their environment are a key component to understand ecological communities. Usually, this kind of data are repeated over time or space for communities and their environment, which leads to a sequence of pairs of ecological tables, i.e. multi-way matrices. This work proposes a new method which is a combined approach of STATICO and Tucker3 techniques and deals to the problem of describing not only the stable part of the dynamics of structure–function relationships between communities and their environment (in different locations and/or at different times), but also the interactions and changes associated with the ecosystems’ dynamics. At the same time, emphasis is given to the comparison with the STATICO method on the same (real) data set, where advantages and drawbacks are explored and discussed. Thus, this study produces a general methodological framework and develops a new technique to facilitate the use of these practices by researchers. Furthermore, from this first approach with estuarine environmental data one of the major advantages of modeling ecological data sets with the CO-TUCKER model is the gain in interpretability.     

Occupational stress, working condition and nutritional status of military police officers

This study aimed to investigate the relationship between stress, working conditions and the nutritional status of 53 military police officers in a Southeast city of Brazil. In order to evaluate the symptomatology and the stress phase, the Inventory of Stress Symptoms Lipp for Adults - ISSL was utilized. The assessment of the working conditions was performed by means of socio-demographic questionnaire, direct observation and interviews. The nutritional and health conditions were assessed through anthropometric measures, biochemical tests, blood pressure measurements and cardiovascular disease risk calculator. The sample is of the male gender (92.5%) and aging below 40 years old (73.6%). From these, 35.8% showed stress and 68.4% were in the resistance phase, with 31.6% almost burned out. Through the calculation of Chi-square we could find positive association between the BMI and tiredness (P = 0.0188), between the BMI and irritation (P = 0.0005) and the BMI and the appearance of nervous system problems or emotional problems (P = 0.0304), indicating that these statuses or problems could be related to work. We can conclude then, the stress is present among military police officers. No case of critical stress was found, and the stress phases identified are still susceptible to intervention.     

Colonization,coloniality and bio-power: biopolitics in Queensland,Australia

This essay illustrates how a Foucauldian theory of power could re-examine postcolonial, coloniality or colonization contexts, as opposed to the current structuralist and hierarchal theories of understanding power that colonization studies, such as coloniality/modernity or postcolonial studies, use to theorize colonization and race. I argue that a structuralist and hierarchal conceptualization of power relations in understanding colonization and its relationship with racism can be problematic, and that the Foucauldian heterarchical (non-hierarchal) understanding of power relations instead draws a more complete picture of the operation of colonization. In order to demonstrate this claim, I firstly briefly explain how colonization has been mainly theorized through postcolonial and coloniality studies. Then I introduce the relevance of Michel Foucault’s work in the problem of colonization, focusing on his theories of racism and the idea of biopolitics. Then I illustrate how a heterarchical theory of biopolitical power was used against Indigenous Australians in Queensland via the implementation of the Queensland Aboriginals Protection and Restriction of the Sale of Opium Act of 1897. Lastly, I offer some preliminary notes for conceptualizing the global assemblage of the ‘State of Exception’ in the context of colonial Queensland, Australia.     

Firm Size and Ownership Structure: Effects on Motivations for Use of Business Community Involvement Practices

This study presents an empirical investigation of the effects of size and ownership structure of the firm on the motivations for use of business community involvement practices. The “motivation‐mix” conceptual framework composed by commitment, calculation, conformance and caring motivational mechanisms is used for the conduction of eight comparative case studies. Results indicate that (1) size and ownership structure, per se, do not affect the motivations, and (2) high levels of calculation and low levels of caring are observed in one particular combination of size‐ownership structure: large, publicly held firms.     

Pivotal Quantities Based on Sequential Data: A Bootstrap Approach

A bootstrap algorithm is provided for obtaining a confidence interval for the mean of a probability distribution when sequential data are considered. For this kind of data the empirical distribution can be biased but its bias is bounded by the coefficient of variation of the stopping rule associated with the sequential procedure. When using this distribution for resampling the validity of the bootstrap approach is established by means of a series expansion of the corresponding pivotal quantity. A simulation study is carried out using Wang and Tsiatis type tests and considering the normal and exponential distributions to generate the data. This study confirms that for moderate coefficients of variation of the stopping rule, the bootstrap method allows adequate confidence intervals for the parameters to be obtained, whichever is the distribution of data.     

Household registration type and compliance with the “one child” policy in China, 1979–1988

This research analyzes how type of household registration, which reflects the degree of government control, affects compliance with China’s “one child” policy for women at risk during the first decade of implementation. Although socioeconomic and cultural factors have significant effects on four fertility events after first live birth, household registration type is the most important. Furthermore, household registration type interacts with urbanization in such a way that the modernization influence associated with urbanization is more evident for women under less government control. The notable success of China’s family planning program is linked to its unique system of government control.
