Revendo estudos sobre a assistência domiciliar ao idoso

Home care presents itself as a new modality of care for the elderly, especially in Brazil , and has been inserted into public policies. This study aims to identify scientific productions about home care, in order to ascertain which are the contributions of this social dynamic in the elderly. The research was conducted in the databases MEDLINE and LILACS, with articles published between the years 2001- 2011, in Portuguese and English. The combination of keywords used was home care and elderly , elderly and care, and elderly and caregiver, and correspondents in Portuguese. The discussion highlighted the importance of home care, especially for lonely or neglected elderly. The review revealed few studies concerning the social dynamics in the home care of the elderly and the need to broaden the discussion beyond the field of health.

A crise do subprime e seus efeitos sobre os Estados Unidos e reflexos no Brasil

Between December 2007 and June 2009 the United States witnessed 18 months of recession that became known as the subprime crisis. Beginning in the housing market, the crisis moved into the banking and financial markets and spread throughout the entire economy through a domino effect, affecting the majority of other businesses. A major reflection of this was the large rise in unemployment rates due to business slashing jobs in an attempt to preserve cash. Although the crisis has officially ended, the unemployment rate reached over 10% in 2010 in the United States. American's continue to seek new jobs in a very difficult employment market, while attempting to manage the family household budget. American household income, which decreased either by pay cuts, job loss, and the effects of inflation, leads the majority of Americans to declare that the crisis had not yet ended. The crisis has spread to the world in varying degrees. Brazil was one of the countries least affected due to government policies and the large amount of foreign exchange. Although the crisis has affected Brazil only slightly, we will show how it reached this country and how the government solved this problem. This research paper will explain how the subprime crisis began, how it manifested itself in the U.S. economy and throughout the population. Also, it will show the crisis’ effects in Brazil and show some statements from Americans with their respective views and their experiences relative to the crisis

A integração da medicina complementar e alternativa em sistemas de saúde convencionais

Complementary and alternative medicine (CAM) is becoming increasingly popular, and despite of the growing demand for these practices, physicians and CAM-providers work separately and there is no sufficient effort in the promotion of an integrative health care. Questions like differences of concepts and language, lack of scientific evidence through randomized clinical trials, no regulation of CAM-providers, products and services, besides the lack of government policies in this scope, turn the process of integration difficult and threaten the quality of delivery of health care. Through the integrative review method, the purpose of this paper is to discuss the issues involved in the integration process of complementary and alternative medicine into the conventional health care systems (guided by principles of biomedicine), addressing benefits and risks, obstacles to integration and models of integration in the discussion topicsl

University students' assessment of entrepreneurial environments

Entrepreneurial intention is a primary step to create new venture in the entrepreneurial process. Environmental conditions are one of the main factors that are strengthening or weakening intention of prospective entrepreneur. Therefore, it is important to develop conducive environments for entrepreneurship to promote entrepreneurial intention. Moreover, the promoted entrepreneurial intention will raise the rate of new venture creation. This paper investigates the relationships between five key environments for entrepreneurship and entrepreneurial intention. The five entrepreneurial environments are: government policies and procedures, socioeconomic conditions, entrepreneurial and business skills, financial assistance, and non-financial assistance, respectively. Conjoint analysis was used to determine the significance of five environmental factors conducive to entrepreneurial intention. In this conjoint experiment, 1370 decisions were made by 137 university students. Significant relationships were found between all of these environmental factors and intention. Comparative importance of environmental factors was also calculated, along with sub-conjoint analyses based on characteristics of the sample.

An Innovation System Perspective on Adaptation Strategies to Climate Variability and Water Management in India

Government policies play a critical role in influencing market conditions, institutions and overall agricultural productivity. The thesis therefore looks into the history of agriculture development in India. Taking a political economy perspective, the historical account looks at significant institutional and technological innovations carried out in pre- independent and post independent India. It further focuses on the Green Revolution in Asia, as forty years after; the agricultural community still faces the task of addressing recurrent issue of food security amidst emerging challenges, such as climate change. It examines the Green Revolution that took place in India during the late 1960s and 70s in a historical perspective, identifying two factors of institutional change and political leadership. Climate change in agriculture development has become a major concern to farmers, researchers and policy makers alike. However, there is little knowledge on the farmers’ perception to climate change and to the extent they coincide with actual climatic data. Using a qualitative approach,it looks into the perceptions of the farmers in four villages in the states of Maharashtra and Andhra Pradesh. While exploring the adaptation strategies, the chapter looks into the dynamics of who can afford a particular technology and who cannot and what leads to a particular adaptation decision thus determining the adaptive capacity in water management. The final section looks into the devolution of authority for natural resource management to local user groups through the Water Users’ Associations as an important approach to overcome the long-standing challenges of centralized state bureaucracies in India. It addresses the knowledge gap of why some local user groups are able to overcome governance challenges such as elite capture, while others-that work under the design principles developed by Elinor Ostrom. It draws conclusions on how local leadership, can be promoted to facilitate participatory irrigation management.

Afghanistan connection : heroin production, distribution, and consumption

Heroin prices are a reflection of supply and demand, and similar to any other market, profits motivate participation. The intent of this research is to examine the change in Afghan opium production due to political conflict affecting Europe’s heroin market and government policies. If the Taliban remain in power, or a new Afghan government is formed, the changes will affect the heroin market in Europe to a certain degree. In the heroin market, the degree of change is dependent on many socioeconomic forces such as law enforcement, corruption, and proximity to Afghanistan. An econometric model that examines the degree of these socioeconomic effects has not been applied to the heroin trade in Afghanistan before. This research uses a two-stage least squares econometric model to reveal the supply and demand of heroin in 36 different countries from the Middle East to Western Europe in 2008. An application of the two-stage least squares model to the heroin market in Europe will attempt to predict the socioeconomic consequences of Afghanistan opium production.

Strengthening the Reporting of Observational Studies in Epidemiology for respondent-driven sampling studies: "STROBE-RDS" statement.

OBJECTIVES Respondent-driven sampling (RDS) is a new data collection methodology used to estimate characteristics of hard-to-reach groups, such as the HIV prevalence in drug users. Many national public health systems and international organizations rely on RDS data. However, RDS reporting quality and available reporting guidelines are inadequate. We carried out a systematic review of RDS studies and present Strengthening the Reporting of Observational Studies in Epidemiology for RDS Studies (STROBE-RDS), a checklist of essential items to present in RDS publications, justified by an explanation and elaboration document. STUDY DESIGN AND SETTING We searched the MEDLINE (1970-2013), EMBASE (1974-2013), and Global Health (1910-2013) databases to assess the number and geographical distribution of published RDS studies. STROBE-RDS was developed based on STROBE guidelines, following Guidance for Developers of Health Research Reporting Guidelines. RESULTS RDS has been used in over 460 studies from 69 countries, including the USA (151 studies), China (70), and India (32). STROBE-RDS includes modifications to 12 of the 22 items on the STROBE checklist. The two key areas that required modification concerned the selection of participants and statistical analysis of the sample. CONCLUSION STROBE-RDS seeks to enhance the transparency and utility of research using RDS. If widely adopted, STROBE-RDS should improve global infectious diseases public health decision making.

Slow Cities: Sustainable Places in a Fast World

This article examines the Slow Food and Slow City movement as an alternative approach to urban development that focuses on local resources, economic and cultural strengths, and the unique historical context of a town. Following recent discussions about the politics of alternative economic development, the study examines the Slow City movement as a strategy to address the interdependencies between goals for economic, environmental, and equitable urban development. In particular, we draw on the examples of two Slow Cities in Germany—Waldkirch and Hersbruck, and show how these towns are retooling their urban policies. The study is placed in the context of alternative urban development agendas as opposed to corporate-centered development. We conclude the article by offering some remarks about the institutional and political attributes of successful Slow Cities and the transferability of the concept.

Environmental Policy in Majoritarian Systems

This paper sheds new light on the determination of environmental policies in majoritarian federal electoral systems such as the U.S., and derives implications for the environmental federalism debate on whether the national or local government should have authority over environmental policies. In majoritarian systems, where the legislature consists of geographically distinct electoral districts, the majority party (at either the national or the state level) favors its own home districts; depending on the location of polluting industries and the associated pollution damages, the majority party may therefore impose sub-optimally high or low pollution taxes due to a majority bias. We show that majority bias can influence the social-welfare ranking of alternative government policies and, in some cases, may actually bring distortionary policies closer to the first-best solution.

Domestic hot water consumption vs. solar thermal energy storage: the optimum size of the storage tank

Many efforts have been made in order to adequate the production of a solar thermal collector field to the consumption of domestic hot water of the inhabitants of a building. In that sense, much has been achieved in different domains: research agencies, government policies and manufacturers. However, most of the design rules of the solar plants are based on steady state models, whereas solar irradiance, consumption and thermal accumulation are inherently transient processes. As a result of this lack of physical accuracy, thermal storage tanks are sometimes left to be as large as the designer decides without any aforementioned precise recommendation. This can be a problem if solar thermal systems are meant to be implemented in nowadays buildings, where there is a shortage of space. In addition to that, an excessive storage volume could not result more efficient in many residential applications, but costly, extreme in space consumption and in some cases too heavy. A proprietary transient simulation program has been developed and validated with a detailed measurement campaign in an experimental facility. In situ environmental data have been obtained through a whole year of operation. They have been gathered at intervals of 10 min for a solar plant of 50 m2 with a storage tank of 3 m3, including the equipment for domestic hot water production of a typical apartment building. This program has been used to obtain the design and dimensioning criteria of DHW solar plants under daily transient conditions throughout a year and more specifically the size of the storage tank for a multi storey apartment building. Comparison of the simulation results with the current Spanish regulation applicable, “Código Técnico de la Edificación” (CTE 2006), offers fruitful details and establishes solar facilities dimensioning criteria.

Evolución del conocimiento del hormigón estructural hasta 1973

Esta tesis analiza los criterios con que fueron proyectadas y construidas las estructuras de hormigón hasta 1973, fecha coincidente con la Instrucción EH-73, que en contenido, formato y planteamiento, consagró la utilización de los criterios modernamente utilizados hasta ahora. Es heredera, además, de las CEB 1970. Esos años marcan el cambio de planteamiento desde la Teoría Clásica hacia los Estados Límite. Los objetivos perseguidos son, sintéticamente: 1) Cubrir un vacío patente en el estudio de la evolución del conocimiento. Hay tratados sobre la historia del hormigón que cubren de manera muy completa el relato de personajes y realizaciones, pero no, al menos de manera suficiente, la evolución del conocimiento. 2) Servir de ayuda a los técnicos de hoy para entender configuraciones estructurales, geometrías, disposiciones de armado, formatos de seguridad, etc, utilizados en el pasado, lo que servirá para la redacción más fundada de dictámenes preliminares sobre estructuras existentes. 3) Ser referencia para la realización de estudios de valoración de la capacidad resistente de construcciones existentes, constituyendo la base de un documento pre-normativo orientado en esa dirección. En efecto, esta tesis pretende ser una ayuda para los ingenieros de hoy que se enfrentan a la necesidad de conservar y reparar estructuras de hormigón armado que forman parte del patrimonio heredado. La gran mayoría de las estructuras, fueron construidas hace más de 40 años, por lo que es preciso conocer los criterios que marcaron su diseño, su cálculo y su construcción. Pretende determinar cuáles eran los límites de agotamiento y por tanto de seguridad, de estructuras dimensionadas con criterios de antaño, analizadas por la metodología de cálculo actual. De este modo, se podrá determinar el resguardo existente “real” de las estructuras dimensionadas y calculadas con criterios “distintos” a los actuales. Conocer el comportamiento de las estructuras construidas con criterios de la Teoría Clásica, según los criterios actuales, permitirá al ingeniero de hoy tratar de la forma más adecuada el abanico de necesidades que se puedan presentar en una estructura existente. Este trabajo se centra en la evolución del conocimiento por lo que no se encuentran incluidos los procesos constructivos. En lo relativo a los criterios de proyecto, hasta mediados del siglo XX, éstos se veían muy influidos por los ensayos y trabajos de autor consiguientes, en los que se basaban los reglamentos de algunos países. Era el caso del reglamento prusiano de 1904, de la Orden Circular francesa de 1906, del Congreso de Lieja de 1930. A partir de la segunda mitad del siglo XX, destacan las aportaciones de ingenieros españoles como es el caso de Alfredo Páez Balaca, Eduardo Torroja y Pedro Jiménez Montoya, entre otros, que permitieron el avance de los criterios de cálculo y de seguridad de las estructuras de hormigón, hasta los que se conocen hoy. El criterio rector del proyecto de las estructuras de hormigón se fundó, como es sabido, en los postulados de la Teoría Clásica, en particular en el “momento crítico”, aquel para el que hormigón y acero alcanzan sus tensiones admisibles y, por tanto, asegura el máximo aprovechamiento de los materiales y sin pretenderlo conscientemente, la máxima ductilidad. Si el momento solicitante es mayor que el crítico, se dispone de armadura en compresión. Tras el estudio de muchas de las estructuras existentes de la época por el autor de esta tesis, incluyendo entre ellas las Colecciones Oficiales de Puentes de Juan Manuel de Zafra, Eugenio Ribera y Carlos Fernández Casado, se concluye que la definición geométrica de las mismas no se corresponde exactamente con la resultante del momento crítico, dado que como ahora resultaba necesario armonizar los criterios de armado a nivel sección con la organización de la ferralla a lo largo de los diferentes elementos estructurales. Los parámetros de cálculo, resistencias de los materiales y formatos de seguridad, fueron evolucionando con los años. Se fueron conociendo mejor las prestaciones de los materiales, se fue enriqueciendo la experiencia de los propios procesos constructivos y, en menor medida, de las acciones solicitantes y, consiguientemente, acotándose las incertidumbres asociadas lo cual permitió ir ajustando los coeficientes de seguridad a emplear en el cálculo. Por ejemplo, para el hormigón se empleaba un coeficiente de seguridad igual a 4 a finales del siglo XIX, que evolucionó a 3,57 tras la publicación de la Orden Circular francesa de 1906, y a 3, tras la Instrucción española de 1939. En el caso del acero, al ser un material bastante más conocido por cuanto se había utilizado muchísimo previamente, el coeficiente de seguridad permaneció casi constante a lo largo de los años, con un valor igual a 2. Otra de las causas de la evolución de los parámetros de cálculo fue el mejor conocimiento del comportamiento de las estructuras merced a la vasta tarea de planificación y ejecución de ensayos, con los estudios teóricos consiguientes, realizados por numerosos autores, principalmente austríacos y alemanes, pero también norteamericanos y franceses. En cuanto a los criterios de cálculo, puede sorprender al técnico de hoy el conocimiento que tenían del comportamiento del hormigón desde los primeros años del empleo del mismo. Sabían del comportamiento no lineal del hormigón, pero limitaban su trabajo a un rango de tensióndeformación lineal porque eso aseguraba una previsión del comportamiento estructural conforme a las hipótesis de la Elasticidad Lineal y de la Resistencia de Materiales, muy bien conocidas a principios del s. XX (no así sucedía con la teoría de la Plasticidad, aún sin formular, aunque estaba implícita en los planteamientos algunos ingenieros especializados en estructuras de fábrica (piedra o ladrillo) y metálicas. Además, eso permitía independizar un tanto el proyecto de los valores de las resistencias reales de los materiales, lo que liberaba de la necesidad de llevar a cabo ensayos que, en la práctica, apenas se podían hacer debido a la escasez de los laboratorios. Tampoco disponían de programas informáticos ni de ninguna de las facilidades de las que hoy se tienen, que les permitiera hacer trabajar al hormigón en un rango no lineal. Así, sabia y prudentemente, limitaban las tensiones y deformaciones del material a un rango conocido. El modus operandi seguido para la elaboración de esta tesis, ha sido el siguiente: -Estudio documental: se han estudiado documentos de autor, recomendaciones y normativa generada en este ámbito, tanto en España como con carácter internacional, de manera sistemática con arreglo al índice del documento. En este proceso, se han detectado lagunas del conocimiento (y su afección a la seguridad estructural, en su caso) y se han identificado las diferencias con los procedimientos de hoy. También ha sido necesario adaptar la notación y terminología de la época a los criterios actuales, lo que ha supuesto una dificultad añadida. -Desarrollo del documento: A partir del estudio previo se han ido desarrollando los siguientes documentos, que conforman el contenido de la tesis: o Personajes e instituciones relevantes por sus aportaciones al conocimiento de las estructuras de hormigón (investigación, normativa, docencia). o Caracterización de las propiedades mecánicas de los materiales (hormigón y armaduras), en relación a sus resistencias, diagramas tensión-deformación, módulos de deformación, diagramas momento-curvatura, etc. Se incluye aquí la caracterización clásica de los hormigones, la geometría y naturaleza de las armaduras, etc. o Formatos de seguridad: Se trata de un complejo capítulo del que se pretende extraer la información suficiente que permita a los técnicos de hoy entender los criterios utilizados entonces y compararlos con los actuales. o Estudio de secciones y piezas sometidas a tensiones normales y tangenciales: Se trata de presentar la evolución en el tratamiento de la flexión simple y compuesta, del cortante, del rasante, torsión, etc. Se tratan también en esta parte del estudio aspectos que, no siendo de preocupación directa de los técnicos de antaño (fisuración y deformaciones), tienen hoy mayor importancia frente a cambios de usos y condiciones de durabilidad. o Detalles de armado: Incluye el tratamiento de la adherencia, el anclaje, el solapo de barras, el corte de barras, las disposiciones de armado en función de la geometría de las piezas y sus solicitaciones, etc. Es un capítulo de importancia obvia para los técnicos de hoy. Se incluye un anejo con las referencias más significativas a los estudios experimentales en que se basaron las propuestas que han marcado hito en la evolución del conocimiento. Finalmente, junto a las conclusiones más importantes, se enuncian las propuestas de estudios futuros. This thesis analyzes the criteria with which structures of reinforced concrete have been designed and constructed prior to 1973. Initially, the year 1970 was chosen as starting point, coinciding with the CEB recommendations, but with the development of the thesis it was decided that 1973 was the better option, coinciding with the Spanish regulations of 1973, whose content, format and description introduced the current criteria. The studied period includes the Classic Theory. The intended goals of this thesis are: 1) To cover a clear gap in the study of evolution of knowledge about reinforced concrete. The concept and accomplishments achieved by reinforced concrete itself has been treated in a very complete way by the main researchers in this area, but not the evolution of knowledge in this subject area. 2) To help the engineers understand structural configurations, geometries, dispositions of steel, safety formats etc, that will serve as preliminary judgments by experts on existing structures. To be a reference to the existing studies about the valuation of resistant capacity of existing constructions, constituting a basic study of a pre-regulation document. This thesis intends to be a help for the current generation of engineers who need to preserve and repair reinforced concrete structures that have existed for a significant number of years. Most of these structures in question were constructed more than 40 years ago, and it is necessary to know the criteria that influenced their design, the calculation and the construction. This thesis intends to determine the safety limits of the old structures and analyze them in the context of the current regulations and their methodology. Thus, it will then be possible to determine the safety of these structures, after being measured and calculated with the current criteria. This will allow the engineers to optimize the treatment of such a structure. This work considers the evolution of the knowledge, so constructive methods are not included. Related to the design criteria, there existed until middle of the 20th century a large number of diverse European tests and regulations, such as the Prussian norm of 1904, the Circular French Order of 1906, the Congress of Liège of 1930, as well as individual engineers’ own notes and criteria which incorporated the results of their own tests. From the second half of the 20th century, the contributions of Spanish engineers as Alfredo Páez Balaca, Eduardo Torroja and Pedro Jiménez Montoya, among others, were significant and this allowed the advancement of the criteria of the calculation of safety standards of concrete structures, many of which still exist to the present day. The design and calculation of reinforced concrete structures by the Classic Theory, was based on the ‘Critical Bending Moment’, when concrete and steel achieve their admissible tensions, that allows the best employment of materials and the best ductility. If the bending moment is major than the critical bending moment, will be necessary to introduce compression steel. After the study of the designs of many existing structures of that time by the author of this thesis, including the Historical Collections of Juan Manuel de Zafra, Eugenio Ribera and Carlos Fernandez Casado, the conclusion is that the geometric definition of the structures does not correspond exactly with the critical bending moment inherent in the structures. The parameters of these calculations changed throughout the years. The principal reason that can be outlined is that the materials were improving gradually and the number of calculated uncertainties were decreasing, thus allowing the reduction of the safety coefficients to use in the calculation. For example, concrete used a coefficient of 4 towards the end of the 19th century, which evolved to 3,57 after the publication of the Circular French Order of 1906, and then to 3 after the Spanish Instruction of 1939. In the case of the steel, a much more consistent material, the safety coefficient remained almost constant throughout the years, with a value of 2. Other reasons related to the evolution of the calculation parameters were that the tests and research undertaken by an ever-increasing number of engineers then allowed a more complete knowledge of the behavior of reinforced concrete. What is surprising is the extent of knowledge that existed about the behavior of the concrete from the outset. Engineers from the early years knew that the behavior of the concrete was non-linear, but they limited the work to a linear tension-deformation range. This was due to the difficulties of work in a non-linear range, because they did not have laboratories to test concrete, or facilities such as computers with appropriate software, something unthinkable today. These were the main reasons engineers of previous generations limited the tensions and deformations of a particular material to a known range. The modus operandi followed for the development of this thesis is the following one: -Document study: engineers’ documents, recommendations and regulations generated in this area, both from Spain or overseas, have been studied in a systematic way in accordance with the index of the document. In this process, a lack of knowledge has been detected concerning structural safety, and differences to current procedures have been identified and noted. Also, it has been necessary to adapt the notation and terminology of the Classic Theory to the current criteria, which has imposed an additional difficulty. -Development of the thesis: starting from the basic study, the next chapters of this thesis have been developed and expounded upon: o People and relevant institutions for their contribution to the knowledge about reinforced concrete structures (investigation, regulation, teaching). Determination of the mechanical properties of the materials (concrete and steel), in relation to their resistances, tension-deformation diagrams, modules of deformation, moment-curvature diagrams, etc. Included are the classic characterizations of concrete, the geometry and nature of the steel, etc. Safety formats: this is a very difficult chapter from which it is intended to provide enough information that will then allow the present day engineer to understand the criteria used in the Classic Theory and then to compare them with the current theories. Study of sections and pieces subjected to normal and tangential tensions: it intends to demonstrate the evolution in the treatment of the simple and complex flexion, shear, etc. Other aspects examined include aspects that were not very important in the Classic Theory but currently are, such as deformation and fissures. o Details of reinforcement: it includes the treatment of the adherence, the anchorage, the lapel of bars, the cut of bars, the dispositions of reinforcement depending on the geometry of the pieces and the solicitations, etc. It is a chapter of obvious importance for current engineers. The document will include an annex with the most references to the most significant experimental studies on which were based the proposals that have become a milestone in the evolution of knowledge in this area. Finally, there will be included conclusions and suggestions of future studies. A deep study of the documentation and researchers of that time has been done, juxtaposing their criteria and results with those considered relevant today, and giving a comparison between the resultant safety standards according to the Classic Theory criteria and currently used criteria. This thesis fundamentally intends to be a guide for engineers who have to treat or repair a structure constructed according to the Classic Theory criteria.
