Fatores associados e preditores de quedas em idosos domiciliados de acordo com a Classificação Internacional da Funcionalidade, Incapacidade e Saúde

Objetivo geral da pesquisa foi identificar os fatores associados e preditivos de quedas em idosos domiciliados em uma cidade do Rio Grande do Sul, Brasil, considerando as características sociodemográficas e epidemiológicas e utilizando-se de fatores ambientais da Classificação Internacional de Funcionalidade, Incapacidade e Saúde (CIF). Objetivos específicos: identificar as características sociodemográficas e epidemiológicas de idosos domiciliados em uma cidade do Rio Grande do Sul, Brasil; descrever os fatores sociodemográficos e epidemiológicos que influenciam nas quedas em idosos domiciliados; Relacionar os fatores ambientais da Classificação Internacional de Funcionalidade, Incapacidade e Saúde em idosos domiciliados com riscos de quedas. Pesquisa epidemiológica transversal, ocorrida de junho a julho de 2013, com 167 idosos das áreas de abrangência de uma unidade básica de saúde. Critérios de inclusão na pesquisa: ambos os sexos, cadastrados e com residência fixa nas áreas de abrangência de uma unidade básica de saúde. Critérios de exclusão: idosos com alterações cognitivas. Utilizou-se entrevista estruturada com três etapas: levantamento das características dos idosos investigados; questões relacionadas às quedas; informações sobre os fatores ambientais da Classificação Internacional de Funcionalidade, Incapacidade e Saúde. Os dados foram agrupados para tratamento estatístico/descritivo. A média das idades 71 anos, com desvio padrão de 7,1. A maioria dos idosos era do sexo feminino, casados, com escolaridade de quatro e oito anos, residindo com filhos e companheiro, aposentados e com renda de um salário mínimo. As doenças mais prevalentes foram circulatórias, osteomusculares, e endócrinas e os idosos apresentaram pelo menos uma comorbidade. Dos 167 idosos, 65 caíram nos últimos doze meses, no ambiente domiciliar, com prevalência em: banheiro, cozinha e na rua, sendo as calçadas as mais destacadas. A maior proporção de permanência no chão foi de dez minutos, e a maioria dos idosos, após as quedas, não procuraram os serviços de saúde. Como tratamento para as quedas, obteve-se o não cirúrgico. Quanto à Classificação Internacional da Funcionalidade, Incapacidade e Saúde, houve destaque para o uso de medicações como fator influente nas quedas dos idosos domiciliados. Percebe-se a importância de avaliação constante por parte dos profissionais de saúde sobre os idosos caidores e não-caidores, no sentido de identificar os fatores de riscos intrínsecos e extrínsecos para implementar estratégias de prevenção que compreendam reabilitação da força muscular, equilíbrio e capacidade funcional, redução da polifarmácia, educação para o autocuidado e um olhar do enfermeiro voltado para os períodos e locais de maior incidência de quedas, melhorando desta forma a qualidade de vida dos idosos residentes em diferentes contextos. A pesquisa traz como contribuição social um re-olhar acerca do redimensionamento do cuidado à pessoa idosa que teve queda no próprio ambiente, a partir da Classificação Internacional de Funcionalidade, Incapacidade e Saúde.

Lecciones aprendidas en la implementación del Manejo Integrado Costero: las experiencias demostrativas del ecosistema Sabana-Camagüey, Cuba

En el archipiélago Sabana-Camagüey, Cuba, y sus áreas marino-costeras, se ha logrado un avance importante en la implementación del Manejo Integrado Costero(MIC) a través del establecimiento de Programas Demostrativos de implementación al nivel de municipios. Para ello fue decisiva la ejecución del proyecto PNUD/GEF Ecosistema Sabana-Camagüey durante casi 20 años. Se describen logros destacados, estrategias y acciones aplicadas, lecciones aprendidas y la importancia de estas para la protección y uso sostenible de la biodiversidad y el enfrentamiento de los peligros de la variabilidad del clima y el cambio climático. Fueron claves: (1) una intensa y sistemática educación, concienciación y capacitación de los actores claves, en temas pertinentes al MIC y a la biodiversidad, desde el comienzo del proyecto, a nivel nacional, provincial y municipios involucrados; (2) la inserción de la ejecución del proyecto dentro del tejido institucional del país; y (3) una fuerte participación de los actores claves (gobiernos, sectores productivos, instituciones científicas y docentes, comunidades y organizaciones no gubernamentales). El proceso de gobernanza de MIC se basó en la concepción y metodología de ECOCOSTAS/Coastal Resource Center-University of Rhode Island,incluyendo la aplicación del conocido ciclo de generación de MIC, los cuatro órdenes de resultados, y el apoyo en los resultados de la ciencia y en el mejor conocimiento general disponibles. Se brindan los resultados recientes de la aplicación, por el proyecto PNUD/ GEF Ecosistema Sabana-Camagüey, de un formulario de autoevaluación anual de desempeño operativo de MIC. La misma se realizó de manera participativa en siete Programas demostrativos de Manejo Integrado Costero para el Ecosistema Sabana-Camagüey, cuyas áreas de intervención fueron declaradas y certificadas por el Ministerio de Ciencia, Tecnología y Medio Ambiente, como “Zonas bajo régimen de Manejo Integrado Costero”. Cada programa de MIC estuvo conducido por el gobierno local y tuvo su estructura particular de composición e de integración. ABSTRACT: In the Sabana-Camagüey archipelago, Cuba, and its coastal marine areas, advances in the implementation of Integrated Coastal Management have been achieved through the establishment of Demonstrative Programs among other actions. For that, the execution of the “Sabana Camagüey Ecosystem” UNDP/ GEF Project during 20 years was decisive. Outstanding outcomes, applied strategies and actions, lessons learned, and their importance for protecting and sustainably use of biodiversity and for facing threats of both climate change and variability are described herein. Key actions were: (1) an intense and systematic stakeholder education, awareness and capacity building to key stakeholders about issues related to ICM and biodiversity since the beginning of the Project, at the involved national, province and municipality levels; as well as (3) a strong participation of key stakeholders (government, productive sectors, scientific and teaching institutions, communities, and non-governmental organizations). The governance process was based on the ECOCOSTAS/Coastal Resource Center-University of Rhode Island conception and methodology, including the application of the known MIC generation cycle, the four result orders, and the support from science and the best available knowledge. Recent results are provided about the application, by the UNDP/GEF Sabana-Camagüey Ecosystem Project, of an annual ICM operative performance self-assessment form. This was carried out in a participative way in seven ICM demonstrative Programs for the Sabana-Camagüey Ecosystem, which intervention areas were declared and certified as “Zones under Integrated Coastal Management Regime”. Each ICM program was led by the local government and had it particular composition and integration structure.

Caracterização das comunidades de aves florestais no distrito de Bragança

Com objetivo de caracterizar a comunidade de aves florestais do Distrito de Bragança, fez-se um estudo em quatro locais de características diferentes sob ponto de vista de estrutura e composição de espécies, através de recolha de informação com base nas listas de 10 espécies de Mackinnon e pelo método captura com redes de neblina, para caracterização das biometrias e parâmetros populacionais, de modo a caracterizar a estrutura das comunidades de aves em cada local. A Combinação dos dois métodos possibilitou a captura e identificação de indivíduos de 44 espécies diferentes, pertencentes a 24 famílias distintas. Destas, as mais representativas foram determinadas através do Índice de Frequência das Listas (IFL) e foram Parus major, Erithacus rubecula, Turdus merula e Sylvia atricapilla. Os resultados referentes à riqueza específica, obtidos através das listas de MacKinnon foram analisados com ANOVA não paramétricas (Kruskal-Wallis). Dos quatro locais, a Ricafé mostrou diferenças significativas na variação de número de espécies. Em relação aos períodos de capturas, o segundo quadrimestre teve número de espécies estatisticamente diferentes dos restantes quadrimestres do ano. No Período de Invernada há menor atividade de aves em todos os locais. Pinhal e Tabuado têm pouca diversidade de espécies.

Successional dynamics in inland dune shrub communities drive changes in functional diversity

Communities can be defined as assemblages of species coexisting under particular environments. The relationship between environment and species are regulated by both environmental requirements –which ultimately determine the species capacity to establish and survive in a particular environment– and the ecological interactions occurring during assembly processes –which also determine community composition by conditioning species coexistence. In this context, plant functional traits are attributes that represent ecological strategies and determine how plants respond to environmental factors and interact with other species. Therefore, the analysis of how traits vary through the dynamics of communities, such as along successions, can give insights about how environmental requirements and species interactions may determine the composition and functional structure of these communities. The xerophytic shrub communities inhabiting inland sand dunes in SW Portugal are characterized by successional processes that are mainly driven by local (edaphic gradients and human disturbance) and regional (climate) processes. Therefore, they constitute an appropriate system for studying species interactions and environmentcommunity co-variations based on functional terms. Using these communities as a model, we evaluate the hypothesis that successional community changes in species composition of xerophytic shrub communities can result in concurrent changes in functional diversity

Inequidad y posición socioeconómica en la reproducción de la actividad física en entornos educativos. Análisis conceptual.

Objetivo: analizar cómo influye la inequidad y la posición socio económica como factores determinantes de la conceptualización de la actividad física, desde la concepción de los determinantes sociales, de forma tal que su revisión conceptual, ayude a constituir la re configuración del concepto de actividad física. Métodos: Exploración de la literatura científica desde la revisión conceptual de artículos seleccionados, utilizando las categorías inequidad y posición socioeconómica para establecer la influencia del concepto de la actividad física en entornos educativos. Y a partir de ella interpretar la re configuración del concepto de la actividad física, desde diferentes concepciones asociadas a los determinantes sociales. Resultados: Se hallaron concepciones de los diferentes autores respecto al concepto de la actividad física. (Peso, raza, índice de masa corporal, edad). Se interpretaron distintos niveles de influencia desde la inequidad y la posición socio económica asociados a la ocupación, el género, sitio de vivienda, nivel de estudio, y la estructura física del entorno. Posteriormente se reportaron resultados desde un análisis explicativo en el cual se interpretan las concepciones de los autores en cuanto al concepto de la actividad física, y como desde ella se establecen relaciones entre la inequidad, la posición socioeconómica y los entornos educativos que incluyen diferentes aspectos sociales para finalmente poder establecer un concepto claro de la re configuración social del concepto de la actividad física, concluyendo que este nuevo concepto social de la actividad física no posee una definición exacta, el análisis de los aspectos sociales de ésta, involucra innumerables concepciones que la influencian y la determinan, en consecuencia el concepto de la actividad física debe ser un concepto en constante evolución y reconfiguración debido a la naturaleza cambiante del ser humano, de las dinámicas sociales y las asociaciones de la salud con los aspectos sociales que se presentan en el diario vivir. Así mismo se evidencia que el concepto de la actividad física se fundamenta en estudios que dejan de lado los aspectos sociales que influencia el concepto y en consecuencia la práctica de la actividad física, esta investigación establece un punto de partida frente a la re configuración social del concepto de la actividad física. Conclusiones: Diferentes organizaciones en el mundo reconocen a la actividad física como una herramienta que favorece la socialización de las personas. Es así como la actividad física, desde el deporte en el campo competitivo y la educación física desde el campo educativo exploran la interacción social de los individuos, esto permite la construcción de valores y fortalece la sana convivencia dentro de las comunidades. Esta trasformación desde el concepto de la actividad física biomédica hasta la actividad física social se evidencia en los documentos revisados, en los cuales la actividad física es estudiada desde las categorías de inequidad y posición socio económica, De ahí que en su conceptualización se involucren diferentes conceptos asociados a los determinantes sociales de la salud, que en definitiva establecen un nuevo concepto de la re configuración social de la actividad física trascendiendo desde la actividad física biomédica o fisiológica hasta un concepto complejo que incluye intereses y particularidades de las personas como lo son la ocupación, la educación, el entorno, el medio ambiente y la estructura física.

Sustainable forest management for smallholder farmers in the Brazilian Amazon.

The paper describes a forest management system to be applied on smallholder farms, particularly on settlement projects in the Brazilian Amazon. The proposed forest management system was designed to generate a new source of family income and to maintain forest structure and biodiversity. The system is new in three main characteristics: the use of short cycles in the management of tropical forests, the low harvesting intensity and environmental impact, and the direct involvement of the local population in ali forest management activities. It is based on a minimum felling cycle of ten years and an annual timber harvest of 5-10 m3 ha-1.

The Effect of occupational sex-composition on earnings: job-specialisation, sex-role attitudes and the division of domestic-labour in Spain

Important theoretical controversies remain unresolved in the literatire on occupational sex-segregation and the gender wage-gap. A useful way of summarising these controversies is viewing them as a debate between - cultural -socialisation. The paper discusses these theories in detail and carries out a preliminary test of the relative explanatory performance of some of their most consequential predictions. This is done by drawing on the Spanish sample of the second wave of the European Social Survey, ESS. The empirical analysis of ESS data illustrates the notable analytical pay-offs that can stem from using rich individual-level indicators, but also exemplifies the statistical llimitations generated by small sample size and high rates of non-response. Empirical results should, therefore, be taken as preliminary. They seem to suggest that the effect of occupational sex-segregation on wages could be explicable by workers' sex-role attitutes, their relative input in domestic production and the job-specific human capital requirements of their jobs. Of these three factors, job-specialisation seeems clearly the most important one.

Effect of gender on ownership and income in veterinary practice

Objective To estimate the effect of gender on ownership and income in veterinary practice in Australia. Methods Questionnaire completed by private veterinary practitioners, and analysed using the SAS System for Windows 7.0. Results More than three-quarters (78%) of male but 36% of female private practitioners were partial or sole owners of practices. The median annual income for all male practitioners working more than 40 hours/week was $70K, but that for females was $43K. These disparities existed in both city and country practices, and in the case of income it increased with increasing time in the workforce. Male practice owners also reported higher incomes than female owners. Conclusions Female veterinary practitioners are less likely to own practices, and more likely to earn low incomes than males. These differentials do not appear to be due to location, hours worked or years since graduation or, in the case of income, to whether they are owners or employees. The evidence points to a lower interest by women than men in the business aspects of veterinary practice.

Optical properties of zirconium oxynitride films: the effect of composition, electronic and crystalline structures

tThis work is devoted to the investigation of zirconium oxynitride (ZrOxNy) films with varied opticalresponses prompted by the variations in their compositional and structural properties. The films wereprepared by dc reactive magnetron sputtering of Zr, using Ar and a reactive gas mixture of N2+ O2(17:3).The colour of the films changed from metallic-like, very bright yellow-pale and golden yellow, for low gasflows to red-brownish for intermediate gas flows. Associated to this colour change there was a significantdecrease of brightness. With further increase of the reactive gas flow, the colour of the samples changedfrom red-brownish to dark blue or even to interference colourations. The variations in composition dis-closed the existence of four different zones, which were found to be closely related with the variationsin the crystalline structure. XRD analysis revealed the change from a B1 NaCl face-centred cubic zirco-nium nitride-type phase for films prepared with low reactive gas flows, towards a poorly crystallizedover-stoichiometric nitride phase, which may be similar to that of Zr3N4with some probable oxygeninclusions within nitrogen positions, for films prepared with intermediate reactive gas flows. For highreactive gas flows, the films developed an oxynitride-type phase, similar to that of -Zr2ON2with someoxygen atoms occupying some of the nitrogen positions, evolving to a ZrO2monoclinic type structurewithin the zone where films were prepared with relatively high reactive gas flows. The analysis carriedout by reflected electron energy loss spectroscopy (REELS) revealed a continuous depopulation of thed-band and an opening of an energy gap between the valence band (2p) and the Fermi level close to 5 eV.The ZrN-based coatings (zone I and II) presented intrinsic colourations, with a decrease in brightness anda colour change from bright yellow to golden yellow, red brownish and dark blue. Associated to thesechanges, there was also a shift of the reflectivity minimum to lower energies, with the increase of thenon-metallic content. The samples lying in the two last zones (zone III, oxynitride and zone IV, oxide films)revealed a typical semi-transparent-optical behaviour showing interference-like colourations only dueto the complete depopulation of the d band at the Fermi level. The samples lying in these zones presentedalso an increase of the optical bandgap from 2 to 3.6 eV.

Globalization and culture shaping the gender gap: A comparative analysis of urban Latin America and East Asia (1970 - 2000)

In this paper we present: 1. The available data on comparative gender inequality at themacroeconomic level and 2. Gender inequality measures at the microeconomic and case studylevel. We see that market openness has a significant effect on the narrowing of the human capitalgender gap. Globalization and market openness stand as factors that improve both the humancapital endowments of women and their economic position. But we also see that the effects ofculture and religious beliefs are very different. While Catholicism has a statistically significantinfluence on the improvement of the human capital gender gap, Muslim and Buddhist religiousbeliefs have the opposite effect and increase human capital gender differences.In the second global era, some Catholic Latin American countries benefited from market opennessin terms of the human capital and income gender gap, whereas we find the opposite impact inBuddhist and Muslim countries like China and South Korea where women s economic positionhas worsened in terms of human capital and wage inequality.

On the effect of molecular structure and composition on the photofragmentation of biomolecules

The research on the interaction between radiation and biomolecules pro-vides valuable information for both radiobiology and molecular physics. While radiobiology is interested in the damage inflicted on the molecule upon irradiation, molecular physics exploits these studies to obtain infor-mation about the physical properties of the molecule and the quantum me-chanical processes involved in the interaction. This thesis work investigated how a small change in the structure or composition of a biomolecule changes the response of the molecule to ioniz-ing radiation. Altogether eight different biomolecules were studied: nucleo-sides uridine, 5-methyluridine and thymidine; amino acids alanine, cysteine and serine; and halogenated acetic acids chloro- and bromoacetic acids. The effect of ionizing radiation on these molecules was studied on molecular level, investigating the samples in gas phase. Synchrotron radiation of VUV or soft x-ray range was used to ionize sample molecules, and the subsequent fragmentation processes were investigated with ion mass spectroscopy and ion-ion-electron coincidence spectroscopy. The comparison between the three nucleosides revealed that adding or removing a single functional group can affect not only the bonds from which the molecule ruptures upon ionization but also the charge localiza-tion in the formed fragments. Studies on amino acids and halogenated acetic acids indicated that one simple substitution in the molecule can dramatical-ly change the extent of fragmentation. This thesis work also demonstrates that in order to steer the radiation-induced fragmentation of the molecules, it is not always necessary to alter the amount of energy deposited on the molecules but selecting a suitable substitution may suffice.

Silver colloidal nanoparticles: Effect on matrix composition and structure of Candida albicans and Candida glabrata biofilms

Aim: The aim of this study was to assess the effect of different silver nanoparticles (SN) concentrations on the matrix composition and structure of Candida albicans and Candida glabrata biofilms. Methods and Results: Candida biofilms were developed in 6-well microtiter plates during 48 h. After, these biofilms were exposed to 13·5 or 54 μg SN ml-1 for 24 h. Then, extracellular matrices were extracted from biofilms and analysed chemically in terms of proteins, carbohydrates and DNA. To investigate the biofilm structure, scanning electron microscopy (SEM) and epifluorescence microscopy were used. SN interfered with the matrix composition of Candida biofilms tested in terms of protein, carbohydrate and DNA, except for the protein content of C. albicans biofilm. By SEM, Candida biofilms treated with SN revealed structural differences, when compared with the control groups. Further, SN showed a trend of agglomeration within the biofilms. Epifluorescence microscopy images suggest that SN induced damage on cell walls of the Candida isolates tested. Conclusions: In general, irrespective of concentration, SN affected the matrix composition and structure of Candida biofilms and these findings may be related to the mechanisms of biocide action of SN. Significance and Impact of the Study: This study reveals new insights about the behaviour of SN when in contact with Candida biofilms. SN may contribute to the development of therapies to prevent or control Candida infections. © 2012 The Society for Applied Microbiology.

Effect of Classroom Gender Composition on Students' Development of Self-Regulated Learning Competencies

Success in any field depends on a complex interplay among environmental and personal factors. A key set of personal factors for success in academic settings are those associated with self-regulated learners (SRL). Self-regulated learners choose their own goals, select and organize their learning strategies, and self-monitor their effectiveness. Behaviors and attitudes consistent with self-regulated learning also contribute to self-confidence, which may be important for members of underrepresented groups such as women in engineering. This exploratory study, drawing on the concept of "critical mass", examines the relationship between the personal factors that identify a self-regulated learner and the environmental factors related to gender composition of engineering classrooms. Results indicate that a relatively student gender-balanced classroom and gender match between students and their instructors provide for the development of many adaptive SRL behaviors and attitudes.

A study on the effect of functional distribution of income on aggregate demand

In this thesis, we study the causal relationship between functional distribution of income and economic growth. In particular, we focus on some of the aspects that might alter the effect of the profit share on growth. After a brief introduction and literature review, the empirical contributions will be presented in Chapters 3,4 and 5. Chapter 3 analyses the effect of a contemporaneous decrease in the wage share among countries that are major trade partners. Falling wage share and wage moderation are a global phenomenon which are hardly opposed by governments. This is because lower wages are associated with lower export prices and, therefore, have a positive effect on net-exports. There is, however, a fallacy of composition problem: not all countries can improve their balance of payments contemporaneously. Studying the country members of the North America Free Trade Agreement, we find that the effect on export of a contemporaneous decrease in the wage share in Mexico, Canada and the United States, is negative in all countries. In other words, the competitive advantage that each country gains because of a reduction in its wage share (to which is associated a decrease in export prices), is offset by a contemporaneous increase in competitiveness in the other two countries. Moreover, we find that NAFTA is overall wage-led: the profit share has a negative effect on aggregate demand. Chapter 4 tests whether it is possible that the effect of the profit share on growth is different in the long run and in the short run. Following Blecker (2014) our hypothesis is that in the short run the growth regime is less wage-led than it is in the long run. The results of our empirical investigation support this hypothesis, at least for the United States over the period 1950-2014. The effect of wages on consumption increases more than proportionally compared to the effect of profits on consumption from the short to the long run. Moreover, consumer debt seem to have only a short-run effect on consumption indicating that in the long run, when debt has to be repaid, consumption depends more on the level of income and on how it is distributed. Regarding investment, the effect of capacity utilization is always larger than the effect of the profit share and that the difference between the two effects is higher in the long run than in the short run. This confirms the hypothesis that in the long run, unless there is an increase in demand, it is likely that firms are not going to increase investments even in the presence of high profits. In addition, the rentier share of profits – that comprises dividends and interest payments – has a long-run negative effect on investment. In the long run rentiers divert firms’ profits from investment and, therefore, it weakens the effect of profits on investment. Finally, Chapter 5 studies the possibility of structural breaks in the relationship between functional distribution of income and growth. We argue that, from the 1980s, financialization and the European exchange rate agreements weakened the positive effect of the profit share on growth in Italy. The growth regime is therefore becoming less profit-led and more wage-led. Our results confirm this hypothesis and also shed light on the concept of cooperative and conflictual regimes as defined by Bhaduri and Marglin (1990).
