Possibilidades de enfoque CTS para o ensino superior de química: proposta de uma abordagem para ácidos e bases

Scientific education has been passing by redefinitions, contestations and new contributions from the research on science teaching. One contribution is the idea of science and technology literacy, allowing the citizens not only knowing science but also understand aspects on the construction and motivation of scientific and technological research. In accordance with this idea, there is the Science-Technology-Society (STS) studies which, since the 1970s, has been contributing for science teaching and learning according to the comprehension of the relationships with society in the Western countries of the North. In Brazil, this approach began to gain projection from the 1990s when the first essays on the theme were published. Currently, there is a clear influence of this approach on the national curriculum guidelines, especially for the area of Natural Sciences, and also on the textbooks chosen by the High School National Program (Programa Nacional do Ensino Médio). However, there seems to be a gap in relation to the discussion on the specific curricular component seen in college on this approach. Thus, this study aims at adopting the approach STS, face to the preparation of complimentary educational material on acid and bases concepts studied in the course of General Chemistry of the Natural Sciences graduation program. To this end, it was performed a bibliographical research aiming at making the state-of-the-art in in these concepts in specific literature to science teaching. It is divided in two stages: systematic study (with sixteen journals chosen according to Qualis-Capes and an unsystematic study with direct search in databases and references in the papers of the systematic study. The studies had their content analyzed and the categories chosen a priori were the level of education, the acid-base theory adopted, and the strategy/theoretical frame of reference adopted. A second stage aimed at identifying attitudes and beliefs on STS (Science-Technology-Society) and CSE (Chemistry-Society-Environment) of students in the teacher and technologist training course in three diferent institutions: UTFPR, UFRN and IFRN. In this study, it was used two questionnaires, composed of a Likert scale, semantic differential scale and open questions. The quantitative data reliability was estimated through Cronbach’s alpha method, and tha data were treated according to classic statistics, using the mean as the centrality measures, and the mean deviation as dispersion. The qualitative data were treated according to the content analysis with categories taken from the reading of answers. In the third stage, it was analyzed the presence of STS and CSE content in chapters on acid and bases concepts of nine General Chemistry textbooks, frequently used in graduation programs in public institutions of the state of Rio Grande do Norte. The results showed that there are few proposals of acid and bases teaching, and they are generally aimed at High School or at instrumentation for teaching courses, and no course for General Chemistry. The student’s attitudes and beliefs show the presence of a positivist point of view based on the concept of Science and Technology neutrality and the salvation of its mediation. The books analysis showed just a few content on STS and CSE are found in the studied chapters, and they are generally presented disjointedly in relation to the rest of the main text. In the end, as suggestion to solve the absence of proposals STS in General Chemistry books, as well as the student’s positivist attitudes, it was developed some educational material to be used in the course of General Chemistry at College. The material is structured to introduce a historical view of the concepts preparation, present the use of materials, the industrial and technological processes, and social and environmental consequences of this activities

Significado do trabalho para trabalhadores da construção civil

The meaning of work is a construct that has been studied more systematically from the 80s, through various approaches and in different occupational categories. This dissertation aims to describe and discuss the meanings of work for construction workers. This is an empirical study whose research supports herself in the Model Attributes Meaning of Work and its respective instrument for measuring the Meaning of Work Inventory (STI). The research involved 402 workers in the construction industry sector in the two capitals of the Brazilian Northeast, with a mean age of 35.8 years (SD = 11.4). To collect the data, besides the IST, the Working Conditions Questionnaire and sociodemographic data were also used. Data were organized and analyzed using the SPSS program. The study used data analysis techniques to Smallest Space Analisys (SSA), descriptive statistics, correlation and analysis of variance. There was evidence of validity of the STI which was structured into five types of value attributes (what work should be), and seven types of descriptive attributes (what is working). The results showed that the work has high centrality and profiling for participants after the family, the most important aspect in the lives of workers. Aspects of personal and economic growth were more emphasized in definition of what the work should be and responsibility and effort were characteristics that best described the reality of work.

Representações sociais de familiares sobre o atendimento das emergências psiquiátricas

The reformist movements in the field of mental health have pointed battle flags, among which the prioritization of production of mental health care out of the asylum environment should be highlighted, aiming the reduction of psychiatric beds, greater control over the hospitalization, family co-participation and the rescue of the citizenship of the social players involved. With the progressive reduction of asylum beds, associated with a lot of structural problems in the health services, the occurrence of crises outside the hospital environment has been increasingly frequent, thus giving the family an important therapeutic role. In face of this scenario, there is an urgent need to understand the social construction of the care for psychiatric emergencies, identifying the meanings assigned by family members to their constituent aspects. This study seeks to answer the following research question: what are the social representations of family members about the care of psychiatric emergencies in the city of Mossoró, Rio Grande do Norte? Therefore, the aim is to analyze the social representations of family members about the care of psychiatric emergencies in the city of Mossoró, Rio Grande do Norte. This is an exploratory and descriptive study, with a mixed approach, making use of multimethods: for collection, the semi-structured interview and the Technique of Free Association of Words; for data analysis, the Thematic Analysis of Bardin and its steps was used, with the informational support of the softwares ALCESTE (Analyse Lexicale par Contexte d'un Ensemble de Segments de Texte) and Iramuteq (Interface de R pour les Analyses Multidimensionnelles de Textes et de Questionnaires); and the theoretical support of social representations. The study participants totaled 72, and they were selected from the following criteria: older than18 years, with degree of kinship with users suffering from some mental and behavioral disorder, and who have already witnessed a situation of crisis, rescued by the SAMU or other means and taken to the psychiatric hospital or general emergency room. Preliminary results point out: 1.Previous note of the research project with the aim to disseminate it in the scientific community and ensure the intellectual property of the work; 2.The contextual analysis of the care for emergencies in the study place. Reflection about the phenomenon provide a name to the care for the psychiatric emergencies, which is called immediate context; the technical and operational aspects that influence the care, as a specific/ general context; and mental health policies in Brazil are identified as metacontext; 3. The systematic review from randomized clinical trials in the databases PubMed, COCHRANE, LILACS, SciELO and SCIRUS, with the use of the descriptors: ‘Physical restraint’, ‘Psychiatric emergency services’, ‘Restraint’, ‘Physical and Emergency Services’, ‘Psychiatric’. Only one work met the search protocol criteria: a short-term essay that records limited results about the proportion of people who are in restraint and seclusion. It does not show statistically significant results in relation to indications, contraindications and risks of the use of physical restraint; 4. The social representations of the care for psychiatric emergencies. The study results point to the presence of five thematic categories: 1. feeling in the face of the crisis/care; 2. thoughts and perspectives about the crisis/care; 3. centrality of care in the medical- medication-hospitalization triad; 4. the thinking/acting in the face of the use of physical restraint and police force; 5. periodicity of crises. The central core of the representation is in the first category, whilst the peripheral elements are in the third and fifth categories. The contrast zone is in the second and fourth categories. The sadness is the most prominent element of the structure. The social representations about the care for psychiatric crises are at a time of transition between the hegemonic and reformist models, with the traditional aspects being predominant, but already showing peripheral and contrast elements that point to a possible change in the representational field.

Química em cena: uma proposta para formação inicial de professores de química

In educational observed difficulty in train teachers to meet the medium and higher education needs, and one reason for this is the different experiences in the training of educators in relation to those found in the classroom. So often arise criticisms related to relevance and efficiency of degree courses, as regards the performance of its natural mission, which weakens the teacher training. Thus, improving the quality of education is very dependent on the initiatives of teachers, creating teaching alternatives to strengthen their performance in school. From this reflection, it is concluded that teacher training needs new educational proposals that qualify, and so can promote the formation of his students more adequately. Among the educational proposals as alternatives to initial teacher training may use the scientific theater (TC). Considering this possibility, this work has been proposed as investigate and discuss the influence of TC combined with experimentation in the initial training of future teachers in Chemistry who participate in the Groups Fanatics chemistry Theatre (UERN) and Chemistry on Stage (UFRN). Therefore, there was, in a first stage, theatrical essays based on the theater of the oppressed, and written dramaturgical scripts, a collaborative proposal. To incorporate experimentation in chemistry to theater rehearsals, there was a systematic literature search and after content analysis, were selected categories, materials and reagents easily accessible, easy procedures and implementation with low risk of accidents and easy care chemical waste. In the second part we identified: a) the beliefs of student teachers in the use of TC ally trial for initial training of chemistry teachers; b) the influence of TC ally to trial on learning of chemical concepts of high school students who attended the shows; c) the reasons for using or not TC ally to trial by chemistry teachers who participated in the TC group and currently work in the classroom. In this study, questionnaires and interviews were used, compounds, respectively, by a Likert scale and open questions. Quantitative data were analyzed by classical statistics the media, using as centrality measures the average, the concordance argument and the average deviation. Qualitative data were discussed according to content analysis, with categories that emerged from reading the answers. These analyzes concluded that the licensees have a positive view on the use of scientific theater for disclosure of the chemical for use in the learning of chemical concepts, pedagogical and disciplinary knowledge, and to form promotion strategy for research and extension at the University. They credit improvements in their initial training on the use of scientific theater combined with experimentation. The TC provides motivation for the construction of conceptual thinking in an informal way of chemical communication, allowing the student to expand their knowledge, not only favoring the phenomenological approach, but also the construction of chemical knowledge and the internalization of scientific concepts.

Vazios urbanos e a dinâmica imobiliária na produção do espaço em Natal

In Brazil, the discussion about the urban voids appear related to the capitalist urban expansion process, when the urban growth act the cities were expanding toward the periphery, leaving in the interstices vacant land, kept out of the market waiting for the real estate valuation. In Natal, the formation of voids was triggered by the process of fragmentation of space promoted mainly by the urban sprawl with the emergence of new neighborhoods, lots of openings, housing developments and the emergence of new lines of commercial centrality. In this sense, this study aims to understand the role played by urban voids in the real estate dynamics and the production process of the Natal city space. For this, it was adressed the concept building on the conception of different authors and were characterized four types of gaps that best explained the phenomenon in the context of the work proposal addressed, such as idle, empty expectant, empty-brownfield areas and institutional areas. For each of these events were considered an example in the general context of the city through semi-structured interviews with technicians, managers and public officials in promoting the city and /or related to management of urban voids.

Do ancoradouro à sala de espera: as obras de melhoramento do porto e a construção de uma Natal moderna (1893-1913)

Through the nineteenth century, it was constant in the discourse of the local norte-rio-grandenses (Natal city, Brazil) administrators, the appeal for subsidy to the central government for the works of the port of Natal upgrade. The port in the capital, the main route of the Rio Grande do Norte communication, because of the limitations attached to it, as the dunes surrounding the city spreading sand in the riverbed, and several reefs located along the coast, did not allow the entry in his berth larger ships. These difficulties brought major problems the province, who could not hold the flow of production coming from the inside, resulting in the north of Rio Grande political scene, questioning the centrality of Christmas position in the province. Only Republican scheme had been approved credit by the federal government for the improvement works of the port. The port became the Republican political discourse Potiguar one of the main promises to bring "progress" the Potiguar land, being placed as a central issue of which depend on the "future" of the state. The objective of this study is to analyse the emergence of a new port concept in speeches and interventions of the local ruling groups in the early twentieth century. We analyse the emergence of a modern notion of port, marked by the organizing effort, rationalization and regulation of port activities by the state, and the new relationship assumed by the harbour front to the city resulting from this new perception. The port has become for local leaders to groups of capital "waiting room", requiring change of the composition of urban space for integrating the port to the city. The Port of Natal became endowed with a pedagogical function, incorporating the urban fabric, codes, values and practices considered by local managers as modern and civilized. This new city space, considered a "waiting room", caused conflicts between the local ruling groups and influential figures in the Potiguar political field, which sought to encourage with the process of organizing the harbour front undesirable regarded figures in the city views as an impediment to the image of progress and modernity that the dominant groups intended to expose the port.

Cidade média do agronegócio: os efeitos da reestruturação produtiva no município de Rio Verde/GO

The average cities inserted in the areas of the Brazilian Cerrado are restructuring in the rural and urban areas in recent decades as a result of agricultural investments. Representative of this process, we chose Rio Verde due to two processes: to develop socioeconomically depending on agricultural production restructuring Cerrado after 1970 and offer average city features regional centrality and intra-urban contradictions. So we have as the problem situation the fact of Rio Verde be inserted in an agricultural region, where the restructured field creates cooperation with the agricultural industry and the tertiary sector, structuring a regional agribusiness success. However, let us doubts about the effects of the restructuring process in socio-economic and environmental terms, in relation to the field and the city. Therefore, the aim of this thesis is to contribute to the discussion about the medium- sized Cerrado cities whose functions are linked to agribusiness, and understand the logic and the effects of the restructuring process in rural and urban areas, having Rio Verde – GO as the reference for studying. Regarding the methodological practice research, it is a qualitative research, developed based on three pillars: theoretical, documentary and field. We conclude the thesis stating that the modern field, the result of agricultural production restructuring, fomented an economy specialized in agribusiness, which led to the enrichment of the field, the formation of agro-industrial complex and the formation of an average city, specializing in agribusiness, whose centrality exceeds its micro-region. In terms of effects, we conclude that process agricultural production restructuring, generated positive impacts for the insertion of Savannahs in the national economy, and to the cities inserted in the modern field. On the other hand, country and city inserted in agricultural regions, masked under the agribusiness speech, perverse effects of socioeconomic and environmental order, is an inviting system to invest and exclusionary, when there is nothing to offer. Thus, the problems are choked on site, leaving only the speech of wealth to be disclosed in the national order.

Brazilian Social Segurity and Social Work: reflections on the Continuous Cash Benefit Programme

Guaranteed under the Federal Constitution of 1988, Brazilian social security covers rights relating to health, social welfare and social care. The Continuous Cash Benefit Programme (BPC) was approved as part of social care policy and is regulated under the Social Care Act (Ley Orgánica de Asistencia Social) of 1993. This benefit guarantees a minimum monthly income for persons with disabilities and for older adults. Certain requirements must be satisfied in order to obtain the assistance: medical and social assessment of disabled persons, a minimum age of 65 years for older adults, and, in both cases, the value of per capita income for the nuclear family in question, which must be lower than a quarter of the minimum wage. Regulation of the BPC has incorporated advances and setbacks in terms of legislation and implementation. In this framework, this article presents a theoretical reflection, an analysis of the legislation on the matter, and some reflections on the challenges that it poses for social workers.

Festival do chocolate da estância turística de Ribeirão Pires: um estudo da cooperação entre microempresas por meio da análise de redes sociais.

O objetivo do presente estudo é identificar a cooperação na rede de microempresas composta pelas barracas do Festival do Chocolate na cidade de Ribeirão Pires, que já ocorre há 9 anos nessa Estância Turística com venda de chocolates, doces, salgados e artesanatos. A pesquisa é exploratória com caráter descritivo. Os dados foram tabulados no software (UCINET), com a obtenção de estatísticas descritivas e métricas de centralidade e densidade. Os dados primários foram coletados por meio de entrevistas semiestruturadas, questionário e observação realizados com 30 representantes das barracas, além do responsável pela Secretaria de Turismo da Cidade. Os dados secundários foram coletados por meio de sites das empresas e órgãos públicos. Como resultado verificou-se que os micro-empresários que participaram nas edições anteriores do evento são as mais procuradas pelos expositores iniciantes que buscam informações sobre o Festival. Além disso, eles trabalham cooperativamente uns com os outros com o objetivo de tornar mais fácil gerir o negócio.

O Impacto das Experiências de Vergonha nos Adolescentes

A presente investigação pretendeu ver cumpridos três dos seus principais objectivos: 1) Adequar e analisar os instrumentos de avaliação em adolescentes, garantindo, medidas confiáveis dos constructos em estudo; 2) Examinar o impacto das experiências de vergonha, verificando se estas podem funcionar como acontecimentos determinantes e centrais na formação da identidade do adolescente; 3) Explorar a relação entre as experiências de vergonha e sintomas de desajustamento psicológico (sintomas de depressão, ansiedade e stress). A amostra é constituída por 397 jovens (190 rapazes e 207 raparigas), com idades compreendidas entre os 12 e os 18 anos (M= 14,91) a frequentar o ensino básio e secundário do sistema regular de ensino. Para além do CES que foi objecto de uma análise mais detalhada, preencheram igualmente os seguintes questionários: ISS, OAS e DASS-21. Os resultados obtidos mostram que indivíduos cujas memórias de vergonha se tornaram pontos de referência na sua identidade, tendem a manifestar valores mais elevados de vergonha externa e vergonha interna. Verificou-se também que indivíduos que apresentam centralidade das memórias de vergonha evidenciam maior vulnerabilidade à sintomatologia psicopatológica, nomeadamente depressão, ansiedade e stress. Por fim, constatou-se que tanto a vergonha externa, como a vergonha interna em adolescentes se apresentam correlacionadas com a psicopatologia. No entanto, a vergonha interna surge mais associada à depressão que a vergonha externa, que se correlaciona mais com a ansiedade e o stress. No que respeita à adaptação das escalas CES, OAS e ISS para a população adolescente, verificou-se que apresentaram boas qualidades psicométricas. Podemos concluir com a nossa investigação, que tal como na população adulta, os adolescentes que experienciaram memórias de vergonha que se tornaram centrais na sua identidade e história de vida, tendem a manifestar níveis mais elevados de vergonha externa e interna. Por outro lado, encontram-se também mais propensos a desenvolver sintomatologia psicopatológica, como a depressão, ansiedade e stress.

Djunta-mó na Procura de uma Vida Melhor

O estudo apresenta-se com o objetivo de compreender diferentes dimensões que interpelam o campo da imigração, evidenciando a relevância das redes sociais e do capital social na mobilidade social dos imigrantes caboverdianos em Portugal. Neste estudo privilegiamos a metodologia qualitativa, dando primazia ao paradigma interpretativo. Foram feitas cinco entrevistas semi-estruturadas a imigrantes caboverdianos adultos residentes na comunidade do Cacém, concelho de Sintra. As narrativas dos imigrantes caboverdianos participantes revelam que as suas redes sociais estão bastantes fragilizadas. A falta de confiança, a escassa participação social em estruturas comunitárias, e o parco djunta-mó que parece existir entre eles, ressaltam como características que parecem inibir os imigrantes de interagir com redes diferentes, fechando-se entre si. Tais características na interação social afetam a emergência e o reforço do capital social necessário para uma integração bem-sucedida, dificultando a mobilidade social ascendente. Sendo a imigração uma importante expressão da questão social, o Serviço Social deveria assumir a centralidade do debate sobre as preocupações do tema apresentado, tanto a nível das características das trajetórias do imigrante, como das suas trajetórias de (não-)integração e in(ex)clusão social. As conclusões do estudo desafiam a (re)pensar as estratégias comunitárias para intervir socialmente no reforço da confiança, entreajuda e participação social, alinhadas com a (re)definição de políticas sociais justas, capazes de potenciar equidade nos processos de mobilidade social ascendente.

As Perdas na Toxicodependência

A toxicodependência tem sido, desde há décadas, um dos mais graves problemas sociais, apesar dos múltiplos esforços – entre os quais se pretendeu integrar a presente investigação – tendentes a reverter a situação. Defendendo a centralidade na pessoa como a abordagem mais correcta e eficaz, baseámos o nosso estudo nas perdas decorrentes do consumo de drogas. Pretendeu-se identificar e analisar as perdas no indivíduo, no seu meio social, assim como, compreender a percepção das perdas e o seu impacto na motivação para o tratamento. Ainda como objectivo, mas secundário, o estudo pretendeu identificar o papel do Assistente Social na reinserção social do toxicodependente no contexto da equipa multidisciplinar. Seguindo uma lógica abdutiva e tomando em consideração que a escolha do campo empírico incidisse num observatório capaz de responder às exigências da investigação, estudámos os percursos de vida de seis residentes da Comunidade Terapêutica Nova Fronteira e de quatro indivíduos frequentadores do grupo de auto-ajuda Narcóticos Anónimos, aos quais efectuámos entrevistas semi-estruturadas e de tipo compreensivo. Para complementar os dados recolhidos, entrevistámos duas técnicas especialistas no tratamento de toxicodependentes. Os resultados obtidos permitem afirmar que os toxicodependentes em recuperação conseguem percepcionar algumas das perdas sofridas. Concluímos, também, que o toxicodependente só encontra motivação para o tratamento quando a consciência da(s) perda(s) sofrida(s) é de tal maneira dolorosa que não lhe deixa alternativas. Relativamente à dimensão da reinserção social, os dados recolhidos não permitem tirar conclusões definitivas. Apenas que, no ciclo vicioso do tratamento/recaída, o processo de reinserção se apresenta descontínuo e fragmentado.
