A Reportagem na tv: Caco Barcellos: um repórter e a injustiça social

Destacar a importância da reportagem investigativa, e mostrar o valor que deve ser observado no empenho da atuação profissional ética de um repórter de televisão, capaz de mudar o rumo da história política recente do Brasil, é o que se propõe o presente trabalho. A prática do jornalismo autêntico demonstra ser transformadora. É o que acontece com a atuação do repórter Caco Barcellos. Ele se propôs a perseguir uma história por mais de um ano e, ao final, mostrar uma verdade escondida durante 30 anos pelo poder público. Com tal reportagem, possibilitou a reparação de uma injustiça social cometida contra uma jovem estudante brasileira. A força da reportagem apresentada num telejornal é incontestável, em razão do potencial que representa a televisão na penetração em todas as camadas da sociedade como veículo de informação. Sendo a reportagem apresentada em série de três dias consecutivos pelo Jornal Nacional, eleva seu peso significativamente, devido à liderança de audiência do telejornal da Rede Globo. O investimento da emissora numa reportagem como a apresentada neste trabalho depende fundamentalmente da presença de um repórter profundamente identificado com a luta contra a injustiça social. E é este o perfil de Caco Barcellos. Ele cresceu na periferia pobre de uma metrópole, e desde muito cedo se revoltou contra a ação policial que discrimina o cidadão comum e privilegia os poderosos. Conseguiu transformar a raiva acumulada em ações efetivas através da reportagem investigativa reveladora da injustiça social cometida diariamente. Quando o espaço era pequeno para o tamanho do que tinha para reportar, Caco lançou livros, ganhou prêmios e enfrentou processos judiciais, movidos por policiais interessados em destruir a vida profissional do repórter que ousou trabalhar sério e encontrar os documentos que provavam os desmandos praticados contra inocentes, friamente assassinados. O resultado é uma atuação exemplar, com um método de trabalho digno de ser seguido, refletindo-se na série de reportagens que desmontou uma farsa montada pelo exército, e que pode ser considerada como uma verdadeira aula de jornalismo.

Situações de risco e proteção à saúde de adolescentes da Comunidade São Remo

No mundo, um em cada cinco pessoas estão na faixa etária de 10 a 19 anos, sendo que 85% habitam países em desenvolvimento (WHO, 2006). Brasil, 21% do total da população está nesta faixa etária (IBGE, 2002). A adolescência é considerada um dos períodos mais saudáveis da vida humana, porém é reconhecido o aumento dos índices de mortalidade em acidentes, suicídios, violência, complicações na gestação e outras doenças que podem ser prevenidas ou tratadas. O objetivo deste estudo é investigar as situações de risco e de proteção à saúde e à vida, vivenciadas por um grupo de adolescentes de baixa renda. É um estudo descritivo qualitativo, realizado na Comunidade São Remo, município de São Paulo, caracterizada pela pobreza e violência. O método utilizado para a coleta de dados foi o grupo focal. Participaram 20 adolescentes, divididos em dois grupos, um de 12 a 14 anos e outro de 15 a 18 anos, foram realizadas três reuniões com cada grupo. As reuniões foram gravadas, posteriormente transcritas e os conteúdos foram analisado, segundo os propostos de Bardin (1977). Os resultados da pesquisa demonstraram que situações de riscos à saúde estão presentes na fragilidade do suporte familiar, violência física causada por terceiros (com ênfase na violência policial), violência psicológica, situações de exclusão social vivenciadas na escola, uso de drogas e condutas transgressoras. Os fatores de proteção detectados foram: família com ênfase na mãe, religiosidade, professor como referência e projetos futuros. Os resultados demonstram que as situações de risco à saúde são mais evidentes do que de proteção para este grupo de adolescentes de baixa renda.

IMPACTO DO CONFLITO INTRAGRUPAL, DO SUPORTE SOCIAL NO TRABALHO E DO AUTOCONCEITO PROFISSIONAL SOBRE A RESILIÊNCIA: UM ESTUDO COM POLICIAIS MILITARES.

A resiliência é um construto que remete à habilidade do ser humano de ter êxito frente às adversidades da vida, superá-las e inclusive, ser fortalecido ou transformado por elas. Campos de investigações da psicologia, como Psicologia da Saúde, Psicologia Positiva e Comportamento Organizacional Positivo, têm considerado a resiliência como uma importante via para a compreensão dos aspectos positivos e saudáveis dos indivíduos. Este trabalho pretendeu ampliar o conhecimento acerca da resiliência e suas relações com outros construtos no contexto organizacional. Para isto, definiu-se como objetivo geral deste estudo verificar a capacidade preditiva do conflito intragrupal (tarefa e relacionamento), do suporte social no trabalho (emocional, informacional e instrumental) e do autoconceito profissional (saúde, realização, autoconfiança e competência) sobre a resiliência (adaptação ou aceitação positiva de mudanças, espiritualidade, resignação diante da vida, competência pessoal e persistência diante das dificuldades) de policiais militares. Participaram do estudo 133 policiais militares de um batalhão do interior do estado de São Paulo, prevalecendo indivíduos do sexo masculino (97,7%), com idade média de 30 anos (DP= 5,7). Para a medida das variáveis foram utilizadas as seguintes escalas validadas: Escala de Avaliação de Resiliência reduzida, Escala de Conflitos Intragrupais, Escala de Percepção de Suporte Social no Trabalho e a Escala de Autoconceito Profissional. Os dados foram submetidos a cálculos descritivos e a análises de regressão linear múltipla padrão. Os resultados indicaram que o modelo que reunia as variáveis antecedentes (conflito intragrupal, suporte social no trabalho e autoconceito profissional) explicou significativamente a variância das dimensões da resiliência: 30% da persistência diante das dificuldades, 29% da adaptação ou aceitação positiva de mudanças, 28% da competência pessoal e 11% da espiritualidade. As variáveis que tiveram impacto estatisticamente importante sobre a persistência diante das dificuldades foram o suporte emocional no trabalho, cuja direção da predição foi inversa, e autoconfiança, cuja direção da predição foi direta. A adaptação ou aceitação positiva de mudanças teve como preditor inverso a variável saúde e como preditor direto a autoconfiança. A competência pessoal teve impacto significativo da variável autoconfiança, que se mostrou um preditor direto. A espiritualidade, por sua vez, teve um único preditor significante, a variável realização, cuja direção da predição foi direta. Os resultados sugerem que dentre as variáveis antecedentes, o autoconceito profissional evidenciou maior poder de explicação da variância da resiliência. À luz da literatura da área foram discutidos estes achados. Por fim, foram apresentadas as limitações e a proposta de uma agenda de pesquisa que contribua para confirmação e ampliação dos resultados desta investigação.

Estratégias de cuidados por familiares de portadores de transtornos mentais severos residentes na zona rural do alto sertão paraibano

In the current configuration of the Brazilian Psychiatric Reform, family plays a key role in mental health care: shared responsibility and active participation in the process of rehabilitation of people with severe mental disorders. It´s considered that the family member who cares can help users in their daily tasks and articulating trajectories, networks and ways to potentiate social connections. This research was motivaded by interest in the subject and by the lack of research and studies about this reality in rural areas. This study aimed to identify ways of mental health care by relatives of severe mental disorder patients living in rural zone located at sertão of Paraiba. Methodologically was made a work with qualitative research structured in two moments. In the first one, was held a Documentary Research in CAPS II in order to identify: a) users living in rural that had a history of at least one psychiatric hospitalization, b) users who no longer use the reference service (CAPS II) for at least one year. The second stage consisted by home visits and semi-structured interviews with eleven families in rural areas. Results pointed out a profile composed by 56 users: 56 women and 26 men aged between 50 and 64 years, unmarried, without study, farmers and housewives, living six miles from CAPS II and carriers with severe mental disorders. Strategies and resources used by the families for mental health care were: religion, work, medication and help from relatives, neighbors and community. Factors related to non-use of substitute services were lack of internment in CAPS II and lack of money and transportation. The hospital, the house arrest, the police aid and religion were strategies used by family members as support to psychiatric crises. The data pointed to non-solving of care offered by psychosocial support network and the importance of redirecting practices aligned to the asylum model in favor of psychosocial strategies that aimed at rehabilitation and community participation in mental health care

A constituição desmilitarizada: democratização e reforma do sistema constitucional de segurança pública

The normative construction of the public security system in the Constituent Assembly of 1987-1988 preserved paradoxical normative space, the military police linked to the Army with a restrictive legal statute of the police offices citizenship through a hierarchical and disciplinary model that is anachronistic. This research originates from the following problem: How is it possible to tailor the constitutional system of public safety, specifically the Military Police, according to the democratic paradigms constructed by the Constituent from 1988 and carry the right to public safety under these molds? The militarists limitations of the Constitution allowed the growing militarization of police departments, organizational culture and authoritarian institutional practices. Underlying this, the problems related to difficulties in realization of Right to Public Safety, the strikes of the military police, the incomplete policy cycle started demanding from the constitutional-legal system appropriate responses. Utilizing the dialogical method and an interdisciplinary approach to the subject, and theoretically grounded in overcoming of the constitutional normativist juspositivism.It was found that the constructed infraconstitutional legislation was insufficient to supply the systemic shortcomings of constitutional law, when looking to create a single system of public security without giving due scope to the federal principle and expand the autonomy the Federated States, and even grant democratic legal status to the military police. Formal legal limits imposed by the Constitution constructed a legal anachronism, the military police. Thus, a democratic reading of military police institutions becomes inconceivable its existence in the constitutional regulatory environment. Thus, reform the Constitution in order to demilitarize the police and conduct a normative redesign of the public security system is fundamental to Brazilian constitutional democracy

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.

Estudo comparativo da capacidade de assamento de dois fornos solares com diferentes configurações

This research is presented as a comparative study about the baking capacity of two box type ovens, produced from a packing case used to equipment transportation. The two ovens have different internal settings, with the greenhouse effect and the concentration of incident solar radiation as the main parameters of differentiation. The main features of the ovens are the low cost, the reuse of materials, the manufacturing and assembly processes simplified, the easy management and the ability of baking a variety of foods simultaneously. The manufacturing and operation of the ovens can be handled by any social and intellectual level of people. The feasibility of the ovens to bake the tested foods was proved with success, ensuring the supremacy of the mirrored oven. The results obtained for both ovens were competitive even with the conventional gas oven, producing the baking of three cakes with 750g in just 80 minutes.

Segurança do paciente em terapia intensiva neonatal: identificação e análise de eventos adversos

The patient safety is a major concern in health services for its global dimension, as evidenced by the fragility of care processes that predispose an occurrence of adverse events. These events in a neonatal intensive care unit are considered serious and hazardous to lives of newborns. The present study aimed to identify and analyze adverse events in a neonatal intensive care unit based in Trigger Tool. It is an epidemiological, cross-sectional , exploratory, retrospective study with quantitative, descriptive and analytical approach, performed in 2015 at a school hospital. The sample was not probabilistic, involving 116 newborns who met the eligibility criteria. Data collection was performed by retrospective review of medical records, using a specific kind of "trigger" instrument, composed of sentinel events in neonatology, adapted from the American model used by the Vermont-Oxford Network. Data were analyzed using descriptive and inferential statistics. The chi-square test for linear trend was used to assess the associations between the variables of interest. The research received a favorable agreement from Ethics Committee of the Federal University of Rio Grande do Norte, under number 1055533, and Presentation Certificate for Ethics Assessment 43894515.6.0000.5537. The results show among investigated newborns, 110 experienced at least one adverse event during their stay, with a total of 391 medical records analyzed and rate of 3.37 events per patient. Prevailed the preterm newborns with low birth weight, from mother who had hypertensive diseases during pregnancy and urinary tract infection. The average hospitalization time was 25 days, associated with hospital-acquired infections events (p = 0.01). Among the identified adverse events stood out the events related to thermoregulation disorders (39.0%), with prevalence of hypothermia (26.0%), followed by health care-related infections (16.4%) and blood glucose disorders, hypoglycemia (9.00%) and hyperglycemia (6.64%). Most of these incidents were classified in categories E and F, which represents that there was damage small proportion. Due to these damages come from the care practice with newborn, 78% were classified as avoidable. There was statistically significant association between the variable birth weight with infections (p = 0.006) as well as peri/intraventricular bleeding (p = 0.02), hypoglycemia (p = 0.021), hyperglycemia (p = 0.001), hyperthermia (p = 0.39) and death (p=0,02). Gestational age was associated with seizures (p = 0.002), hyperglycemia (p=0.017) e hyperthermia (p=0.027). The security institution culture was reported by the health workers as intermediate, even though the number of adverse events found in only one unit of service indicates that there is much to be done. Thus the high rate of adverse events identified in the neonatal intensive care unit reinforces the necessity to elaborate specific preventive strategies for this risk environment.

Projeto de intervenção adaptando o Balanced Scorecard ao sistema de compras da Base Aérea de Natal

The present proposal for intervention examines the issue of public procurements carried out by a military organization on a Federal Public Administration. The main objective of this paper is to propose a model of strategic planning based on the Balanced Scorecard for the public procurement system, which contributes to increased efficiency, efficacy and effectiveness of acquisitions made in the Air Base of Natal city. Therefore, Structured interviews were used in order to make a diagnosis of the current reality of the procurement system along with the main requirement sectors of BANT, as well as the adaptation of the prospects of the BSC based on literature review. The technique used for the analysis of the interviews was the analysis of content whose results contributed to the preparation of the conceptual Strategic Map which was submitted to validation through a Focal Group. It was concluded through the analysis of the interviews, that the system of purchases of BANT is in a tactical profile because of low interaction between the system of purchases and the requirement sectors, aiming only at the “economicity” of acquisition in opposition of the effectiveness of material acquired, the lack of training of the elements which build the system and the absence of a proper planning. It is intended with thecreation of this proposal to contribute to the improvement of management with a focus on results in public administration as well as increasing efficiency, efficacy and effectiveness of public procurements. Whereas for the particular case the measurement of the results can only be performed after at least a year of its implementation, the present research constitutes a proposal of intervention.

"Ad nostram scientiam referatur": la supervisión administrativa imperial de la aplicación de las leyes durante la dinastía constantiniana

Constantino y sus sucesores, Constancio II, Constante y Juliano, expresaron su particular interés por supervisar la aplicación de determinadas leyes imperiales mediante el uso de la fórmula ad nostram scientiam referatur y de otras similares. Constantino fue el príncipe que la empleó con más frecuencia, especialmente durante el período de 313-324, exceptuando el intervalo de 315-316, cuando la confrontación con Licinio le obligó a renunciar a atender directamente las cuestiones administrativas. La progresiva disminución de la inclusión de estas cláusulas en los textos legales imperiales a partir de la unificación del Imperio en 324 se debe poner en relación con la aparición de los curiosi y luego de los agentes in rebus, como oficiales encargados de vigilar la observancia de las normas vigentes.

Salvajes y chichimecas: mitos de alteridad en las fuentes novohispanas

Llamamos mitos de alteridad a las creencias y el imaginario tradicionales que un pueblo proyecta en su visión etnocéntrica sobre otros pueblos. Siguiendo la propuesta de Roger Bartra, examinamos una serie de crónicas novohispanas para demostrar que los mitos de alteridad de origen europeo referentes al salvaje influyeron en las descripciones que nos han legado sobre los pueblos indígenas mesoamericanos conocidos como chichimecas. Apuntamos finalmente algunas reflexiones sobre el uso y alcance de dichos mitos de alteridad en relación con la expansión europea por América, y sobre la necesidad metodológica de someter a crítica bajo este prisma la información que nos ofrecen las fuentes disponibles, producidas, después de todo, en pleno proceso de aculturación colonial.

Comprometimento Organizacional, Autocriticismo e Autocompaixão na PSP

Introdução: São poucos os estudos que em Portugal se dedicaram a explorar constructos como o autocriticismo, autocompaixão, saúde mental e o comprometimento organizacional. São nossos objetivos analisar estas associações na Polícia de Segurança Pública, considerando igualmente a influência de variáveis sociodemográficas e profissionais, bem como realizar análises preditivas que permitam verificar quais são as variáveis preditores do comprometimento organizacional. Metodologia: A amostra é constituída por 188 polícias com idades compreendidas entre os 30 e 56 anos (M = 43,75, DP = 5,66). Os participantes preencheram um protocolo integrante do projeto Organizar Positivamente do Instituto Superior Miguel Torga, composto por um questionário sociodemográfico, a SELFCS (Escala da Autocompaixão), a FSCRS (Escala das Formas do Autocriticismo e Autotranquilização), o MHI-5 (Mental Health Inventory) e o QCO (Questionário do Comprometimento Organizacional). Resultados: Os polícias parecem regular a sua relação com a organização através do comprometimento calculativo. A autocompaixão associa-se positivamente ao comprometimento afetivo, sobressaindo a capacidade de mindfulness. O autocriticismo, na forma eu inadequado - menos corrosivo que a forma eu detestado -, revela uma relação positiva com o comprometimento calculativo, pelo que a permanência na organização pode ser emocionalmente negativa, originar ataques ao eu e diminuir a capacidade afetiva. Porém, a capacidade autotranquilizadora (forma eu tranquilizador do autocriticismo) parece capacitar os polícias para o desenvolvimento de maiores níveis de comprometimento organizacional e afetivo. A idade, a antiguidade e menos habilitações literárias parecem favorecer o comprometimento calculativo. Discussão: A autocompaixão pode contribuir para uma atitude positiva e afetuosa do polícia para com a organização. Assim, através de uma intervenção baseada na autocompaixão e no mindfulness, com impacto positivo no comportamento afetivo e normativo, não só se poderá preservar e promover a saúde e o bem-estar dos polícias, mas também fomentar o empenho organizacional, atenuando os efeitos negativos da profissão policial. Esta abordagem poderá contribuir para os objetivos organizacionais, através da supressão das emoções aversivas, da diminuição da intenção de turnover e abandono da organização. / Introduction: There are few studies in Portugal that have been dedicated to explore constructs such as self-criticism, self-compassion, mental health and organizational commitment. Our goals are to analyze these associations at the Public Safety Police, considering also the influence of sociodemographic and professionals variables, as well as to conduct predictive analyses, in order to verify which variables may predict organizational commitment. Methodology: The sample consisted of 188 police with ages between 30 and 56 years (M = 43.75, SD = 5.66). The participants filled in a protocol from the project Organizar Positivamente, from Instituto Superior Miguel Torga, composed by a sociodemographic questionnaire, the SELFCS (Self-Compassion Scale), the FSCRS (Scale of Forms of Self-Criticism and Self-Reassurance, the MHI-5 (Mental Health Inventory) and the QCO (Organizational Commitment Questionnaire). Results: The police officers appear to regulate their relationship with the organization through calculative commitment. Self-compassion is associated positively to affective commitment, with mindfulness showing to be the most important competence in this professional group. Self-criticism, in its inadequate self form – which is less corrosive than the hated self form - reveals a positive relationship with calculative commitment, which might imply that staying in the organization may be emotionally negative, may provoke attacks against the self and diminish the affective capacity. However, the self reassurance capacity (reassure self form of self-criticism) may enable the police officers to develop higher levels of organizational commitment and affective commitment, as well. Age, seniority and fewer qualifications seem to support the calculative commitment. Discussion: Through self-compassion police officers may experience a positive and warmth attitude towards the organization. Thus, an intervention program based on self-compassion and mindfulness may stimulate affective and normative commitment, not only preserving and promoting health and the well-being of police officers, but also fostering organizational commitment and mitigating negative effects in the police profession. This approach may contribute to organizational goals’ through the suppression of aversive emotions, decreasing turnover and intention to abandon the organization.

Studio di termoresistenza di lieviti fermentativi

In anni recenti il potenziale degradativo dei lieviti nelle bevande ha assunto un’importanza crescente a causa degli importanti danni economici ad essi associati e i produttori sono sempre più attenti a queste problematiche, anche in relazione alla tendenza di ridurre i trattamenti termici, in una strategia di risparmio energetico e di riduzione del danno termico organolettico. L’obiettivo dell’elaborato è stato quello di testare la termoresistenza di diversi ceppi di lieviti che possono costituire un rischio per bevande di fantasia: sette appartenenti alla specie Saccharomyces cerevisiae, tre Zygosaccharomyces, un ceppo di Saccharomycodes ludwigii, uno di Schizosaccharomyces pombe e uno di Kluyveromyces marxianus. Le prove di termoresistenza sono state condotte in vitro utilizzando terreno di coltura impiegando temperature di 55°C, 60°C e 65°C e i dati sono stati modellati con l’equazione di Weibull per ottenere le curve di morte termica dei diversi ceppi. Questo modello permette di tenere conto dell’approccio vitalistico dell’interazione tra temperatura e cellula e descrive l’inattivazione microbica come risultato del fallimento delle cellule nel contrastare le condizioni ostili dovute all’alta temperatura. I risultati hanno dimostrato che i ceppi erano caratterizzati da termoresistenza molto variabile. In generale, tra le specie non Saccharomyces, i più resistenti erano K. marxianus e Sch. Pombe mentre tra i Saccharomyces il più resistente era il ceppo SPA, isolato in uno stabilimento di bevande e responsabile di un incidente industriale che ha portato all’alterazione di oltre 500000 bottiglie di bibite gassate. Questo screening preliminare per la valutazione della termoresistenza ad un potenziale trattamento industriale ha permesso di individuare i lieviti più resistenti che saranno poi oggetto di un successivo studio in cui verranno tenuti presenti altri fattori tecnologici e di prodotto per poi potersi muovere in un ambiente industriale.
