Planejamento ambiental da bacia hidrográfica do Rio Guapi-Macacu: estudo da paisagem e qualidade ecológica

Os estudos de relação entre a paisagem e a água doce vêm sendo aprofundados pela comunidade científica e pelos propositores de políticas públicas, principalmente, para atender às demandas sobre as maneiras que este sistema ambiental pode ser alterado e na identificação das implicações políticas e ecológicas destas mudanças. Quanto mais se torna intenso e diversificado o uso dos corpos hídricos e da paisagem em bacias hidrográficas maior é a necessidade de se definir formas de planejamento, gerenciamento e gestão ecológica desses ecossistemas. O completo entendimento do funcionamento e dos processos ecológicos que ocorrem em uma bacia hidrográfica exige conhecimento simultâneo de seus sistemas aquáticos e terrestres, da biodiversidade, da fisiografia, da geologia e de sua conservação, temporal e espacial. Este entendimento e conhecimento da área de interesse são vitais para proposições de instrumentos ambientais legais, como Unidades de Conservação (UCs). É muito importante que a fundamentação destas propostas tenha como eixo principal o funcionamento dos ecossistemas e das paisagens, de forma a garantir uma maior conectividade e integração entre água (doce, salobra e salgada) e terra, e seus múltiplos usos. A presente tese foi desenvolvida com base neste contexto, apresentando e aplicando metodologias integradoras, seja na ecologia de paisagem (EP), seja na relação entre os ambientes dulcícola e terrestre. O objetivo principal deste trabalho foi o desenvolvimento de processos para planejamento ambiental em BHs, através do diagnóstico, compreensão e análise do funcionamento e dinâmica da paisagem e de ecossistemas de rios e córregos, apoiados no uso de geotecnologias. De acordo com os resultados obtidos, a BHGM ocupa uma área de 1260,36 km e 204,69 km de perímetro. É uma bacia com forma mais alongada que circular (KC = 1,6144e IC =0,4747 km/km) que indica uma menor susceptibilidade a enchentes em condições normais de precipitação exceto em eventos de intensidades anômalas. O mapeamento base (2007) realizado indicou que a bacia possuía 34,86% de uso antrópico e 64,04 % de remanescente florestal. Os dados de fitofisionomia potencial indicaram predominância da classe Florestas Ombrófila Densa Submontana (40%) e de Terras Baixas (39%). Foram estabelecidas para bacia 269 unidades de paisagem (integração da geomorfologia, geologia, fitofisionomia e uso da terra e cobertura vegetal (2007)) que junto com os dados de métrica de paisagem constituíram a proposta integrativa da tese para ecologia de paisagem. Em relação à qualidade ambiental foram adotados o índice de avaliação visual (IAV), o índice multimétrico físico-químico bacteriológico e o índice biótico estendido (IBE). A comparação entre estes índices demonstrou a confirmação entre os seus resultados para a maioria dos pontos amostrados nas áreas de referência e de pelo menos dois índices para os pontos intermediários e impactados. Foram propostos também dois cenários para a bacia: um considerando as condicionantes e medidas compensatórias vinculadas à licença prévia do complexo petroquímico do Estado do Rio de Janeiro (COMPERJ); e outro, sem considerar estas condições. O primeiro indicou a realização da restauração ecológica, seguindo as diretrizes do mapa síntese, integrada para restauração da paisagem.

Da responsabilidade civil por abandono afetivo

This study, in the Family Law area, aims to examine the civil liability for emotional distance from a multidisciplinary perspective. The work and reflection made thereunder tend to corroborate the cognizance that self-representation, sociability and the ability of future adults to define their life’s projects, depend, to a large extent, on the emotional stability and maturity that has been assured to them, as children, by the material and emotional care that has been provided to them by both parents. It is therefore crucial to tend to the feelings of loss and to the potential lack of self-esteem that the affective rupture with either parents may cause. Thus, we promote an analysis of the sustainability, under Portuguese law, of the imposition of compensatory measures, independent from other injunctions foreseen in civil and guardianship law, upon the dissolution of family ties in result of a guilty injury of parental obligations, which have caused serious and evident injuries to the children.

Análise do conforto térmico da cidade de Mirandópolis/SP em seus espaços abertos

Mirandópolis/SP appeared in 1934 from the railroad “the Brazil Northwest”, that there it served one of the points of its stretch that had as main function to drain the agricultural production northwestern native of São Paulo of that time. The installation of the town happened absent of concerns with initial urbanístico planning, thus modifying its natural landscape and modifying characteristic ambient without compensatory measures aiming at a future expansion of the urban mesh. Fact this that still causes today consequences the quality of life of the people and also the observed thermal comfort later. Ahead of this, the present work had for objective to identify through measurements of temperature and relative humidity of the city of Mirandópolis/SP the differences that in the fabric urban they corroborate for a comfort situation or thermal discomfort to the outdoors in accordance with the Diagram Bioclimático de Olgyay the collection of data was made throughout the month of July of 2011 involving the attainment of information of Temperature and relative humidity of air and questionnaire applied to the passer-bys in the act of the measurements. Also approaching the different thermal dynamic of the zones of housing in relation to the Urban Cannyon that develops the commerce as predominant activity. This research sample that, although a city to be small, the quality of life of its inhabitants is not only guaranteed by the transport or that its thermal comfort reveals inside homogeneous of the urban perimeter, but that it has yes heterogeneidade in the scope of the urban climate in these spaces

Wind Farm Facilities in Germany Kill Noctule Bats from Near and Far

Over recent years, it became widely accepted that alternative, renewable energy may come at some risk for wildlife, for example, when wind turbines cause large numbers of bat fatalities. To better assess likely populations effects of wind turbine related wildlife fatalities, we studied the geographical origin of the most common bat species found dead below German wind turbines, the noctule bat (Nyctalus noctula). We measured stable isotope ratios of non-exchangeable hydrogen in fur keratin to separate migrants from local individuals, used a linear mixed-effects model to identify temporal, spatial and biological factors explaining the variance in measured stable isotope ratios and determined the geographical breeding provenance of killed migrants using isoscape origin models. We found that 72% of noctule bat casualties (n = 136) were of local origin, while 28% were long-distance migrants. These findings highlight that bat fatalities at German wind turbines may affect both local and distant populations. Our results indicated a sex and age-specific vulnerability of bats towards lethal accidents at turbines, i.e. a relatively high proportion of killed females were recorded among migratory individuals, whereas more juveniles than adults were recorded among killed bats of local origin. Migratory noctule bats were found to originate from distant populations in the Northeastern parts of Europe. The large catchment areas of German wind turbines and high vulnerability of female and juvenile noctule bats call for immediate action to reduce the negative cross-boundary effects of bat fatalities at wind turbines on local and distant populations. Further, our study highlights the importance of implementing effective mitigation measures and developing species and scale-specific conservation approaches on both national and international levels to protect source populations of bats. The efficacy of local compensatory measures appears doubtful, at least for migrant noctule bats, considering the large geographical catchment areas of German wind turbines for this species.

The impact and compensation of offshore wind farm development: Analysing the institutional discourse from a french case study

In France, the public acceptability of marine renewable energies and their impacts on ecosystem services (ES) involves questions about compensation for stakeholders, who may perceive some of their activities and interests to be modified. This paper seeks to understand how impacts on ES are perceived by institutional stakeholders and what is expected in terms of compensation. It also seeks to identify the communities of practice affected. We focus our study on the planned offshore wind farm in the bay of Saint-Brieuc. Our results show that institutional discourse is heterogeneous, depending on sensitivities, interests, and who or what the stakeholders surveyed represent or defend. Stakeholders' discourse can be interpreted on various gradients of perception. Six distinct communities of practice have been identified, based on the impacts perceived by institutional stakeholders. Lastly, we show that the community of practice seems to be a proper level at which to study perceptions and assess the no-net-loss goal.

Análise de programas de educação ambiental no licenciamento ambiental de usinas hidrelétricas no Rio Grande do Sul : um estudo de caso

O trabalho intitulado - Análise de programas de Educação Ambiental no licenciamento ambiental de usinas hidrelétricas no Rio Grande do Sul: um estudo de caso - busca fazer uma análise compreensiva, reflexiva e problematizadora das ações de Educação Ambiental realizadas durante o processo de licenciamento ambiental, como medidas mitigadoras e/ou compensatórias de impactos ambientais causados pela instalação/operação de empreendimentos hidrelétricos. O objeto de análise foi o Programa de Educação Ambiental da UHE São José, instalada no rio Ijuí, interior do estado. Utilizou-se o movimento recursivo e reflexivo para elaboração da pesquisa, onde a primeira fase foi composta pelo levantamento bibliográfico que serviu de base para as discussões propostas, e a segunda fase foi composta pela investigação do referido programa, tendo como corpus da pesquisa documentos e entrevistas, e utilizando-se da Análise Textual Discursiva (ATD) como metodologia de análise. Os resultados obtidos fazem refletir sobre a ocupação dos espaços do licenciamento ambiental por uma Educação Ambiental que vá além do simples cumprimento das leis e normas, mas que seja de fato integradora e participativa, e envolva o compromisso dos empreendedores, das comunidades atingidas e dos órgãos fiscalizadores, contribuindo com a gestão ambiental e a sustentabilidade dos locais em transformação.

Compensatory Health Beliefs Predict Maladaptive Coping, Impulsivity, and Erroneous Health Perceptions

Compensatory Health Beliefs (CHB) are a common strategy used to reduce the cognitive discomfort that arises from participating in recognizably unhealthy behaviors. The current research examines relationships between CHB and other cognitive variables. Data was collected in two phases, using survey methodology. Study 1 explored relationships between the use of CHB, impulsiveness, and coping styles. Study 2 expanded the inquiry by exploring relationships to health perception and knowledge. Results revealed that participants who scored high on overall CHB were more likely to: engage in maladaptive coping strategies (r = .47, p < .01) [including avoidant coping styles (r = .38, p < .01) and unhealthy coping styles (r = .47, p < .01)], score higher on measures of impulsivity (r = .43, p < .01), be well-informed about their general health (r =-.21, p < .05), eat fast food more often ( r = p < .05), and consider it safe to smoke more frequently (r = .18, p < .05). Participants with lower CHB scores considered themselves more well-informed about their general health (r = -.21, p < .05), including understanding the minimum recommended amounts of physical activity needed to maintain health (r = -.35, p < .01 ), and knowing the health risks of stress ( r = -.19, p < .05). In addition, maladaptive coping was positively correlated with lack of general health knowledge (r = -.22 p < .01), less understanding of the risks of stress and alcohol (r = .20, p < .05), less knowledge of the recommended daily amounts of physical activity needed for health (r = -.26, p < .01), less frequent exercise (r = -.26, p < .01 ), and generally more unhealthy daily habits (r = -.26, p < .01). These findings contribute to a new area of investigation and may be useful to those who want to motivate behavior change.

Liposuction induces a compensatory increase of visceral fat which is effectively counteracted by physical activity: a randomized trial

Context: Liposuction is suggested to result in long-term body fat regain that could lead to increased cardiometabolic risk. We hypothesized that physical activity could prevent this effect. Objective: Our objective was to investigate the effects of liposuction on body fat distribution and cardiometabolic risk factors in women who were either exercise trained or not after surgery. Design, Setting, and Participants: Thirty-six healthy normal-weight women participated in this 6-month randomized controlled trial at the University of Sao Paulo, Sao Paulo, Brazil. Interventions: Patients underwent a small-volume abdominal liposuction. Two months after surgery, the subjects were randomly allocated into two groups: trained (TR, n = 18, 4-month exercise program) and nontrained (NT, n = 18). Main Outcome Measures: Body fat distribution (assessed by computed tomography) was assessed before the intervention (PRE) and 2 months (POST2), and 6 months (POST6) after surgery. Secondary outcome measures included body composition, metabolic parameters and dietary intake, assessed at PRE, POST2, and POST6, and total energy expenditure, physical capacity, and sc adipocyte size and lipid metabolism-related gene expression, assessed at PRE and POST6. Results: Liposuction was effective in reducing sc abdominal fat (PRE vs. POST2, P = 0.0001). Despite the sustained sc abdominal fat decrement at POST6 (P = 0.0001), the NT group showed a significant 10% increase in visceral fat from PRE to POST6 (P = 0.04; effect size = -0.72) and decreased energy expenditure (P = 0.01; effect size = 0.95) when compared with TR. Dietary intake, adipocyte size, and gene expression were unchanged over time. Conclusion: Abdominal liposuction does not induce regrowth of fat, but it does trigger a compensatory increase of visceral fat, which is effectively counteracted by physical activity.

Prospective memory rehabilitation for adults with traumatic brain injury: A compensatory training programme

Primary objective: To describe a prospective memory rehabilitation programme based on a compensatory training approach and report the results of three case studies. Research design: Programme evaluation using pre-and post-intervention assessments and telephone follow-up. Methods and procedures: Three participants with traumatic brain injury completed 8 weeks of training with 1 - 2 hour individual sessions. Assessments were formal prospective memory assessment, self-report and measures of diary use. Experimental interventions: Intervention aimed to identify potential barriers, establish self-awareness of memory deficits, introduce a customized compensatory tool, a cueing system and organizational strategies. A significant other was involved in training to assist generalization. Main outcomes and results: All three participants improved on formal prospective memory assessment and demonstrated successful diary use after the programme. Self-report of prospective memory failure fluctuated and may reflect increased self-awareness. Conclusion: A compensatory approach may be useful in improving prospective memory performance following TBI.

Compensatory effects of parent and peer support on well -being and achievement during pre- and early adolescence

The current study was designed to explore the salience of parent and peer support in middle childhood and early adolescence across two time periods as indicated by measures of achievement (grade point average (GPA), Stanford Achievement Test (SAT) scores and teacher rated school adaptation) and well-being (loneliness, depression, self-concept and teacher-rated internalizing behaviors). ^ Participants were part of an initial study on social network relations and school adaptation in middle childhood and early adolescence. Participants at Time 1 (in the spring of 1997) included 782 children in grades 4 and 6 of eight lower and middle income public elementary schools. Participants (N = 694) were reinterviewed two years later in the spring of 1999 (Time 2). ^ Multivariate analyses of variance (MANOVA) were used to investigate the change in salience of parent and peer support from Time 1 to Time 2. In addition, Tukey-HSD (Honestly Significant Difference) post hoc tests were used to test the significance of the differences among the means of four support categories: (1) low parent-low friend, (2) low parent-high friend, (3) high parent-low friend, and (4) high parent-high friend. ^ Compensatory effects were observed for loneliness and self-concept at Time 1, as well as for SAT scores, self-concept and overall achievement at Time 2. Results were consistent with existing findings that suggest a competitive model of parent/peer influence on achievement during adolescence. This study affirms the need for a more contextual approach to research examining competing and compensatory effects on adolescent development. ^
