CARACTERÍSTICAS PSICOSSOCIAIS E DE PERSONALIDADE DE ADOLESCENTES INFRATORES EM CUMPRIMENTO DE MEDIDA SOCIOEDUCATIVA

Para atingir os objetivos propostos, ou seja, levantar e descrever indicadores socioculturais de uma amostra de adolescentes em cumprimento de medida socioeducativa, e descrever características psicológicas e de personalidade dos adolescentes infratores, num estudo que pesquisou adolescentes em cumprimento de medida socioeducativa. O trabalho foi realizado em duas as etapas: na primeira, os 47 adolescentes participaram de uma entrevista semidirigida; na segunda, dez desses adolescentes foram selecionados e submetidos a um instrumento projetivo para investigação de aspectos da personalidade: o “desenho da Figura Humana” de Machower, adaptado por Van Kolck (1956; 1984). A discussão teórica dos resultados baseou-se numa abordagem psicanalítica pós-freudiana para a compreensão da adolescência tanto como fase do desenvolvimento humano como dos comportamentos antissociais. Os resultados do estudo corroboraram a teoria advinda da literatura psicológica que aborda padrões comuns no período da adolescência, fase em que ocorre um complexo de fatores individuais da maturidade biológica associados ao meio social/cultural e que, por sua vez, estabelecem relações com as instâncias psicológicas ou psíquicas do sujeito junto com as características específicas de cada indivíduo. Na busca da compreensão desses padrões comuns da amostra dos adolescentes infratores utilizados no presente estudo, foram levantados dados do perfil psicossocial, cultural e demográfico; dos aspectos psicossociais e aspectos psicodinâmicos e de características de personalidade. A título de conclusão, o estudo destacou a problemática do adolescente em conflito com a lei, associada às questões sociais, de saúde mental, além do desenvolvimento psíquico, sinalizando a necessidade de ações psicoprofiláticas voltadas para população infantil, jovem, agrupamentos familiares e para a comunidade que representa seu entorno.

Tények, adatok és mutatószámok felhasználásának anomáliái (The anomalies of the usage of facts, data, and indexes)

Tudomány nem létezik a tények felmérése, adatok gyűjtése és felhasználása nélkül. A tényeket azonban el lehet hallgatni vagy ferdíteni, az adatokat sokféleképpen lehet összeválogatni, az azokból készült mutatószámokat pedig a bonyolult és változó valóság leegyszerűsítő, sőt meghamisító ábrázolására, illetve magyarázatára is fel lehet használni. _____ Economics cannot do without measuring. However, the required data are not always available or they are not reliable, as some cases of population census exemplify it. The indicators we use, particularly composite indexes, are often misleading because they oversimplify complex phenomena or processes, and neglect important non-measurable ones, as the examples of the per capita GDP indicator measuring the development level of countries, and the composite indexes measuring the “human development” of countries (HDI), or their “national competitiveness” (GCI) may show. To avoid the enchantment of numbers, the quantitative approach must always be combined and corrected by a critical, holistic and qualitative approach.

Sustainable Development: The Search for the Tipping Point

The United Nations recently launched the Decade of Education for Sustainable Development. Literature indicates the need for an authoritative definition of sustainable development. Sustainable Human Development is analyzed through the lens of Gladwell’s The Tipping Point as a framework for guiding ethical development practice and instigating changes in human behavior.

Toward an understanding of how individuals overcome challenges to development: A phenomenological study of an inner -city student's attitude toward academic orientation and life

The purpose of this qualitative case study was to gain an understanding of the phenomenon of academic orientation by seeking the insights into an inner-city Haitian-American middle school student's attitudes and world view toward education and life. A phenomenological approach was used in order to explore the way in which Cindy, a minority student, gives meaning to her lived-experiences in terms of her desire to meet academic expectations and her ability to overcome social adversity and/or other risk factors.^ The study attempted to answer the following two research questions: (1) What provides the focus for Cindy's (the subject's) approach to her school work and/or life? (2) What are the processes that give meaning and direction to academic orientation and life for Cindy? In-depth interviewing was the primary method of data collection. In addition, journal and sketchbook entries and school district records were used and classroom observations made.^ The nature of the study to understand lived-experience facilitated the use of the case study method and a phenomenological method of description. Data analysis was conducted by means of an adapted form of the constant comparative approach. Patterns in the data which emerged were coded and categorized according to underlying generative themes. Phenomenological reflection and analysis were used to grasp the experiential structures of Cindy's experience. The following textural themes were identified and confirmed to be essential themes to Cindy's experience: personal challenge to do her best, personal challenge to want to learn, having a sense of determination, being able to think for self, having a disposition to like self, achieving self-respect through performance, seeing a need to help others, being intrinsically motivated, being an independent learner, attending more to academic pressure and less to peer pressure, having motivational catalysts in her life, learning and support opportunities, and having a self-culture. Using Mahrer's humanistic theory of experiencing, Cindy's development was interpreted in terms of her progression through a sequence of developmental plateaus: externalized self, internalized self, and integrating and actualizing self.^ The findings of this study were that Cindy's desire to meet academic expectations is guided by a meaning construction internal frame of reference. High expectations of self in conjunction with other protective factors found in Cindy's home and school environments were also found to be linked to her educational resilience and success. Cindy's lived-experiences were also found to be related to Mahrer's theory of human development. In addition, it was concluded that "minority" students do not all fit into social categories and labels. ^

The role of the transcription factor Ets1 in melanocyte development

Melanocytes, pigment-producing cells, derive from the neural crest (NC), a population of pluripotent cells that arise from the dorsal aspect of the neural tube during embryogenesis. Many genes required for melanocyte development were identified using mouse pigmentation mutants. The deletion of the transcription factor Ets1 in mice results in hypopigmentation; nevertheless, the function of Ets1 in melanocyte development is unknown. The goal of the present study was to establish the temporal requirement and role of Ets1 in murine melanocyte development. In the mouse, Ets1 is widely expressed in developing organs and tissues, including the NC. In the chick cranial NC, Ets1 is required for the expression of Sox10, a transcription factor critical for the development of melanocytes, enteric ganglia, and other NC derivatives. ^ Using a combination of immunofluorescence and cell survival assays Ets1 was found to be required between embryonic days 10 and 11, when it regulates NC cell and melanocyte precursor (melanoblast) survival. Given the requirement of Ets1 for Sox10 expression in the chick cranial NC, a potential interaction between these genes was investigated. Using genetic crosses, a synergistic genetic interaction between Ets1 and Sox10 in melanocyte development was found. Since Sox10 is essential for enteric ganglia formation, the importance of Ets1 on gut innervation was also examined. In mice, Ets1 deletion led to decreased gut innervation, which was exacerbated by Sox10 heterozygosity. ^ At the molecular level, Ets1 was found to activate a Sox10 enhancer critical for Sox10 expression in melanoblasts. Furthermore, mutating Ets1 at a site I characterized in the spontaneous variable spotting mouse pigmentation mutant, led to a 2-fold decrease in enhancer activation. Overexpression and knockdown of Ets1 did not affect Sox10 expression; nonetheless, Ets1 knockdown led to a 6-fold upregulation of the transcription factor Sox9, a gene required for melanocyte and chondrocyte development, but which impairs melanocyte development when its expression is prolonged. Together, these results suggest that Ets1 is required early during melanocyte development for NC cell and melanoblast survival, possibly acting upstream of Sox10. The transcription factor Ets1 may also act indirectly in melanocyte fate specification by repressing Sox9 expression, and consequently cartilage fate.^

Direitos fundamentais sociais no Brasil: desafios e mecanismos para sua concretização

The work referred to above, in order to contribute to the legal issues, economic, political and social of the violation of social rights, performs even firmer approach to various implementation mechanisms of social rights in Brazil. Therefore, it begins the study dealing with aspects and important characters of the rights under discussion, as its normative forecast, concept, classifications; respect of social rights with the existential minimum; the principle of reservation of the possible and the need to use this principle as optimization commandment of state resources and the deficit of the realization of social rights in the country. This, in later chapters, in an interdisciplinary approach, challenges and proposals for the realization of social rights by bringing in each chapter, mechanisms for such implementation. That way, as a general objective, it has been to contribute to the discussed problems, when present proposals for the realization of social rights in the Brazilian context. As specific objectives, as well as record the key aspects of the rights in allusion, the one has to promote the perspective of economic development and taxation as posts instruments that the State must be focused on the promotion of social rights by registering in this context that nonexistent economic development without reducing poverty, misery and social inequality and adding that there should be a directly proportional relationship between the tax burden in the country and the human and social development index; analyze the achievement of budget control as essential and healthy measure for the realization of social rights; highlight the importance of society to the achievement of unavailable social interests, affirming the need for the implementation of participatory democracy and, in this line, brings knowledge of the Constitution and the constitutional sense as elements that provide the constitutional progress. Finally, it presents a study on public policies, considering that these are equivalent to the primary means of the promotion of social rights. That way it analyzes the stages that integrate public policies, ranging from the perception of social problems for evaluation and control of the policies implemented; debate about the administrative discretion in when it comes to public policies; brings the classification of essential public policies, the relationship of these with the existential minimum, control parameters and, finally, the legalization of public policy, regarded as legitimate to remedy the unconstitutional state failure and give normative effectiveness and strength to the defining constitutional rules for fundamental social rights. It uses to achieve the objectives outlined, the bibliographic and normative approach method and performs an analysis of jurisprudence related understandings to matter. In the conclusions, it rescues the most important aspects elucidated at work, with the aim of giving emphasis to the proposals and mechanisms that contribute to the solution of the discussed problems.

The Effects of Brominated Flame Retardants on Thyroid Hormone Homeostasis in Human Placenta Tissues and Cell Culture

Polybrominated diphenyl ethers (PBDEs) are a class of brominated flame retardants (BFRs) that have been heavily used in consumer products such as furniture foams, plastics, and textiles since the mid-1970’s. BFRs are added to products in order to meet state flammability standards intended to increase indoor safety in the event of a fire. The three commercial PBDE mixtures, Penta-, Octa-, and DecaBDE, have all been banned in the United States, however, limited use of DecaBDE is still permitted. PBDEs were phased out of production and added to the Stockholm Convention due to concerns over their environmental persistence and toxicity. Human exposure to PBDEs occurs primarily through the inadvertent ingestion of contaminated house dust, as well as though dietary sources. Despite the phase-out and discontinued use of PBDEs, human exposure to this class of chemicals is likely to continue for decades due to the continued use of treated products and existing environmental reservoirs of PBDEs. Extensive research over the years has shown that PBDEs disrupt thyroid hormone (TH) levels and neurodevelopmental endpoints in rodent and fish models. Additionally, there is growing epidemiological evidence linking PBDE exposure in humans to altered TH homeostasis and neurodevelopmental impairments in children. Due to the importance of THs throughout gestation, there is a great need to understand the effects of BFRs on the developing fetus. Specifically, the placenta plays a critical role in the transport, metabolism, and delivery of THs to the fetal compartment during pregnancy and is a likely target for BFR bioaccumulation and endocrine disruption. The central hypothesis of this dissertation research is that BFRs disrupt the activity of TH sulfotransferase (SULT) enzymes, thereby altering TH concentrations in the placenta.

In the first aim of this dissertation research, the concentrations of PBDEs and 2,4,6-TBP were measured in a cohort of 102 placenta tissue samples from an ongoing pregnancy cohort in Durham, NC. Methods were developed for the extraction and analysis of the BFR analytes. It was found that 2,4,6-TBP was significantly correlated with all PBDE analytes, indicating that 2,4,6-TBP may share common product applications with PBDEs or that 2,4,6-TBP is a metabolite of PBDE compounds. Additionally, this was the first study to measure 2,4,6-TBP in human placenta tissues.

In the second aim of this dissertation research, the placenta tissue concentrations of THs, as well as the endogenous activity of deiodinase (DI) and TH SULT enzymes were quantified using the same cohort of 102 placenta tissue samples. Enzyme activity was detected in all samples and this was the first study to measure TH DI and SULT activity in human placenta tissues. Enzyme activities and TH concentrations were compared with BFR concentrations measured in Aim 1. There were few statistically significant associations observed for the combined data, however, upon stratifying the data set based on infant sex, additional significant associations were observed. For example, among males, those with the highest concentrations of BDE-99 in placenta had T3 levels 0.80 times those with the lowest concentration of BDE-99 (95% confidence interval (CI): 0.59, 1.07). Whereas females with the highest concentrations of BDE-99 in placenta had T3 levels 1.50 times those with the lowest concentration of BDE-99 (95% CI: 1.10, 2.04). Additionally, all BFR analyte concentrations were higher in the placenta of males versus females and they were significantly higher for 2,4,6-TBP and BDE-209. 3,3’-T2 SULT activity was significantly higher in female placenta tissues, while type 3 DI activity was significantly higher in male placenta tissues. This research is the first to show sex-specific differences in the bioaccumulation of BFRs in human placenta tissue, as well as differences in TH concentrations and endogenous DI and SULT activity. The underlying mechanisms of these observed sex differences warrant further investigation.

In the third aim of this dissertation research, the effects of BFRs were examined in a human choriocarcinoma placenta cell line, BeWo. Michaelis-Menten parameters and inhibition curves were calculated for 2,4,6-TBP, 3-OH BDE-47, and 6-OH BDE-47. 2,4,6-TBP was shown to be the most potent inhibitor of 3,3’-T2 SULT activity with a calculated IC50 value of 11.6 nM. It was also shown that 2,4,6-TBP and 3-OH BDE-47 exhibit mixed inhibition of 3,3’-T2 sulfation in BeWo cell homogenates. Next, a series of cell culture exposure experiments were performed using 1, 6, 12, and 24 hour exposure durations. Once again, 2,4,6-TBP was shown to be the most potent inhibitor of basal 3,3’-T2 SULT activity by significantly decreasing activity at the high and medium dose (1 M and 0.5 M, respectively) at all measured time points. Interestingly, BDE-99 was also shown to inhibit basal 3,3’-T2 SULT activity in BeWo cells following the 24 hour exposure, despite exhibiting no inhibitory effects in the BeWo cell homogenate experiments. This indicates that BDE-99 must act through a pathway other than direct enzyme inhibition. Following exposures, the TH concentrations in the cell culture growth media and mRNA expression of TH-related genes were also examined. There was no observed effect of BFR treatment on these endpoints. Future work should focus on determining the downstream biological effects of TH SULT disruption in placental cells, as well as the underlying mechanisms of action responsible for reductions in basal TH SULT activity following BFR exposure.

This was one of the first studies to measure BFRs in a cohort of placenta tissue samples from the United States and the first study to measure THs, DI activity, and SULT activity in human placenta tissues. This research provides a novel contribution to our growing understanding of the effects of BFRs on TH homeostasis within the human placenta, and provides further evidence for sex-specific differences within this important organ. Future research should continue to investigate the effects of environmental contaminants on TH homeostasis within the placenta, as this represents the most critical and vulnerable stage of human development.

Time beyond clock: time use-surveys revisited

Time use surveys -despite having represented a turning point in the study of inequalities between women and men- continue hiding care times and subtracting relevance to the qualitative dimensions of time. This due both, to the ideological conception that lies behind this type of studies that consider more relevant market process as to surveys methodology. This article analyzes the theoretical model that lies behind time use surveys and, consequently, the study of the conceptual aspects, the methodology and the potential of these surveys as an analytical instrument. The aim is to unraveling the limitations presented by the surveys to take in account the subjective dimensions of time related to the wellbeing of  people.

Estrategias resilientes ante la situación adversa de los desahucios

Los desahucios en España se han convertido en los últimos años en un fenómeno social emergente, de interés tanto para la investigación como para la intervención de los profesionales de la acción social. Aun así, no existen estudios suficientes relacionados con esta situación adversa, y menos aún centrados en las respuestas resilientes que las personas son capaces de ofrecer ante ella. Con el objetivo de identificar los factores internos y externos que se presentan en la experiencia de las familias que viven procesos de desahucios y que les están permitiendo desarrollar estrategias resilientes ante dicha adversidad, se lleva a cabo la presente investigación en la que participan 20 sujetos, pertenecientes a familias que acuden a la Plataforma de Afectados por las Hipotecas (PAH) de Málaga. A los participantes se les realiza una entrevista semi-estructurada y a través de ellas se han podido definir las características socio-familiares de las personas afectadas, las diferentes estrategias de afrontamiento desarrolladas, las principales fuentes de apoyo con las que han contado, así como las preocupaciones que les han acompañado. Los resultados muestran los principales factores internos y externos que están presenten en las estrategias resilientes que han desarrollado las familias afectadas por los desahucios durante el proceso vivido y destacan como fuente de apoyo informacional a la PAH. Se concluye con la necesidad de continuar con esta línea de investigación para tratar de diseñar intervenciones que refuercen y fomenten las estrategias de afrontamiento ante la situación adversa del desahucio.

BIBLIOTECA EN BORUCA.... UNA REFLEXIÓN

Boruca es una comunidad que está situada al sur del país, en la provincia de Puntarenas. Su extensión en territorio es de 12.470 hectáreas y según el censo poblacional del 2000 tiene una población de 1.386 indígenas, entre la cual hay una importante cantidad de niños, niñas y adolescentes en edad escolar, así como también egresados/as de secundaria.Según el informe sobre desarrollo humano en Centroamérica y Panamá del 2004:"tener acceso al conocimiento es un factor que determina en gran medida el bienestar actual y futuro de las personas. El conocimiento implica por una parte, acceso a la educación o capacitación y por otra, acceso a información pertinente, veraz y oportuna. Se ha establecido que un más alto nivel de formación de las personas contribuye a que gocen de un mejor estado de salud, alcancen empleos superiores y obtengan mayores ingresos. El nivel y calidad de la formación es un factor importante en la promoción personal, en el ascenso social y en el progreso colectivo del país"Partiendo de lo anterior, reflexiono que en las comunidades indígenas de nuestro país no existen unidades de información que sirvan de apoyo en sus procesos de enseñanza y aprendizaje, tampoco cuentan con un espacio físico de encuentro donde los y las jóvenes y las demás personas puedan expresar sus destrezas, sus gustos por la lectura, buscar información y usar la tecnología. Y qué pasa además con sus necesidades básicas, ¿estarán cubiertas?, ¿sus problemas diarios tendrán solución?, ¿vivirán en condiciones de extrema pobreza?, ¿cuentan con suficientes alimentos?, ¿sus relaciones familiares son armoniosas? Por lo tanto, ¿esimportante una biblioteca en la comunidad?, ¿para qué serviría y apoyaría a estas poblaciones?

Management and development of enterprise

The research work is devoted to actual problems of development management of industrial enterprises. The general purpose of this work is the choice and justification of rational enterprise development evaluation model and subsequent application of it for assessment of enterprise development level and also forming of recommendations for enterprise management. Theoretical aspects of development management of enterprises were generalized. The approaches to understanding the essence of development enterprise category and its types were considered. It was investigated the evaluation models of enterprise development, their advantages and disadvantages and the difficulties of their implementation. The requirements for formation of the evaluation system of the enterprise development were summarized. It was determined the features of the formation and application of an Index of Enterprise Development. In the empirical part, data about investigated enterprises was collected from their official websites and also complemented with further data from other statistical websites. The analysis was based on the annual financial statements of companies. To assess the level of enterprise development were chosen model proposed by Feshchur and Samulyak (2010). This model involves the calculation of the Index of Enterprise Development using partial indicators, their reference values and weight. It was conducted an analysis of the development of Ukrainian enterprises that produce sauces. OJSC “LZHK” had the highest value of Index of Enterprise Development, in 2013 and 2015, that consisted 0,78 and 0,76 respectively. In 2014 the highest value for the Index belonged to PJSC “Volynholdinh” and amounted 0,74. OJSC “LZHK” had the highest average value of Index of Enterprise Development by the result of 2013-2015 years, and it consisted 0,70. PJSC “Chumak” had the lowest average value of Index of Enterprise Development obtained the result 0,59. In order to raise the enterprise development level, it was suggested to reduce production costs and staff turnover, increase the involvement of employees.

Proposal for the creation of a Center for Learning Resources (CRA) in the School of San Lorenzo de Tarrazu

Education is the basis for economic and social development, but there are great inequalities in education and access to documentary resources, audiovisual and technology, a situation that affects school performance. The Organization of the United Nations Educational and Scientific Organization (UNESCO) found a correlation between levels of inequality in a country and performance: the greater the inequality, the worse the performance. Investment in education affects human development and benefit is obtained for the individual and society, which is necessary to ensure social equity, so that there is quality education for all. One of the fundamental purposes of the educational process is to train Costa Rican human thinking, analytical and critical of their environment. The purpose of that is acquired through various methods of academic achievement, learning, participation and constant communication of knowledge between the administrative staff, faculty and students. It is appropriate for schools and colleges have a school library or Resource Center for Learning, it is the gathering, analysis and work of the educational community, working with the intellectual growth of students, faculty, staff and community through access to different services and learning resources provided by the library or CRA.

CONDICIONES INICIALES PARA UNA POLÍTICA DE DESARROLLO Y DEL MEDIO AMBIENTE. Un enfoque a partir de los derechos concretos a la vida

Resumen En este ensayo se pretende analizar, críticamente, un aspecto que consideramos crucial en toda propuesta de desarrollo, ya sea que éste se entienda como “desarrollo económico”, como “desarrollo humano sostenible”, o como desarrollo a secas: los criterios formales de decisión y sus correspondientes marcos categoriales. Estos criterios se insertan necesariamente en un sistema de coordinación del trabajo social, y condicionan los fines y las metas de la acción. Además, lo hacemos teniendo especialmente en cuenta aquellos rasgos estructurales del subdesarrollo capitalista que creemos necesario enfrentar y superar en toda propuesta de desarrollo: el desempleo, las desigualdades sociales y regionales, la exclusión social y la destrucción del medio ambiente. El análisis presupone una imagen del ser humano que concibe a éste como un sujeto de derechos concretos a la vida, imagen que parte del trabajo humano en el conjunto de la división social del trabajo, y por tanto, de un sujeto en comunidad. Adjudica al ser humano determinados derechos a la vida que tienen que impregnar a la sociedad entera para que pueda ser realmente una sociedad libre.   Abstract This paper attempts analyze, in a critical way, a crucial issue concerning every development proposal: the formal criteria of decision and their respective theoretical frameworks, either we talk about economic development, human development or just development. These criteria are necessarily inserted in a social labor coordination system and they determine those ends and goals of the human action. Moreover, we emphasize those structural features from capitalist underdeveloped countries that are urgent to face and overcome: unemployment, social and regional inequalities, social exclusion and environment destruction. Analysis we do presupposes the human being conceived as a person with concrete rights of live, as from the human labor in the whole of social labor division, and therefore, as a person in a community. Every society, in order to be a free society, must to assign these concrete rights of live to every human being.

Qualidade do sono e trabalho por turnos

O estilo de vida, atualmente, tem bastante influência na higiene do sono. São diversos os fatores que contribuem tanto para a sua manutenção como para a sua falha. O trabalho por turnos está frequentemente associado a elevadas cargas de stresse e fadiga devido a situações imprevisíveis e perigosas que possam advir da área profissional, da rotatividade do horário laboral, a um sono deficiente, à falta de atividades desportivas e de lazer, bem como à má alimentação. Estilo de vida, este, que reduz a qualidade de vida em geral e aumenta drasticamente a probabilidade de surgir doenças quer ao nível físico como mental. O sono, por sua vez, é um fenómeno universal de grande importância para o desenvolvimento humano. A qualidade do sono é determinada por vários fatores, entre eles as rotinas de sono. Torna-se, assim, importante estudar as rotinas de forma a incrementar o conhecimento sobre este determinante. A alternância do dia-noite –claro/escuro -, os horários de trabalho, os horários de lazer, as atividades familiares são todos fatores exógenos que sincronizam o ciclo sono-vigília. Estudar a qualidade de sono em profissionais que trabalham por turnos é de extrema relevância visto tratar-se de uma população cada vez mais em risco e em que se considera que o sono seja um dos fatores mais comprometidos. O presente estudo tem como objetivo caraterizar e avaliar a qualidade do sono em profissionais, em função dos horários de trabalho. A metodologia utilizada é quantitativa e centrou-se na aplicação do questionário IQSP – Índice de Qualidade do Sono de Buysse et al. (1989), adaptado e traduzido para português. O questionário foi aplicado a 50 indivíduos pertencentes à Polícia Marítima, na Zona Norte de Portugal Continental, na maioria (92%) homens com idades compreendidas entre os 36 e os 55 anos. Do total de participantes, 76% (n=38) encontra-se a trabalhar por turnos. A análise dos dados foi efetuada através do Statistical Package for the Social Sciences, versão 22, tendo sido realizadas análises descritivas, inferenciais e correlacionais. Com maior relevância, no presente estudo, conclui-se que não existem diferenças estatisticamente significativas na qualidade do sono entre aqueles que trabalham por turnos e os que têm horário fixo, bem como, que a qualidade do sono também não se diferencia em função da idade, do tempo de profissão e da existência de filhos pequenos. Conclui-se, ainda, que a qualidade do sono parece estar relacionada com a satisfação com o horário de trabalho.
