User-definable resource bounds analysis for logic programs

We present a static analysis that infers both upper and lower bounds on the usage that a logic program makes of a set of user-definable resources. The inferred bounds will in general be functions of input data sizes. A resource in our approach is a quite general, user-defined notion which associates a basic cost function with elementary operations. The analysis then derives the related (upper- and lower-bound) resource usage functions for all predicates in the program. We also present an assertion language which is used to define both such resources and resourcerelated properties that the system can then check based on the results of the analysis. We have performed some preliminary experiments with some concrete resources such as execution steps, bytes sent or received by an application, number of files left open, number of accesses to a datábase, number of calis to a procedure, number of asserts/retracts, etc. Applications of our analysis include resource consumption verification and debugging (including for mobile code), resource control in parallel/distributed computing, and resource-oriented specialization.

Automatic exploitation of non-determinate independent and-parallelism in the basic andorra model

Andorra-I is the first implementation of a language based on the Andorra Principie, which states that determinate goals can (and shonld) be run before other goals, and even in a parallel fashion. This principie has materialized in a framework called the Basic Andorra model, which allows or-parallelism as well as (dependent) and-parallelism for determinate goals. In this report we show that it is possible to further extend this model in order to allow general independent and-parallelism for nondeterminate goals, withont greatly modifying the underlying implementation machinery. A simple an easy way to realize such an extensión is to make each (nondeterminate) independent goal determinate, by using a special "bagof" constract. We also show that this can be achieved antomatically by compile-time translation from original Prolog programs. A transformation that fulfüls this objective and which can be easily antomated is presented in this report.

Some paradigms for visualizing parallel execution of logic programs

This paper addresses the design of visual paradigms for observing the parallel execution of logic programs. First, an intuitive method is proposed for arriving at the design of a paradigm and its implementation as a tool for a given model of parallelism. This method is based on stepwise reñnement starting from the deñnition of basic notions such as events and observables and some precedence relationships among events which hold for the given model of parallelism. The method is then applied to several types of parallel execution models for logic programs (Orparallelism, Determinate Dependent And parallelism, Restricted and-parallelism) for which visualization paradigms are designed. Finally, VisAndOr, a tool which implements all of these paradigms is presented, together with a discussion of its usefulness through examples.

Some considerations on the compile-time analysis of constraint logic programs

This paper discusses some issues which arise in the dataflow analysis of constraint logic programming (CLP) languages. The basic technique applied is that of abstract interpretation. First, some types of optimizations possible in a number of CLP systems (including efficient parallelization) are presented and the information that has to be obtained at compile-time in order to be able to implement such optimizations is considered. Two approaches are then proposed and discussed for obtaining this information for a CLP program: one based on an analysis of a CLP metainterpreter using standard Prolog analysis tools, and a second one based on direct analysis of the CLP program. For the second approach an abstract domain which approximates groundness (also referred to as "definiteness") information (i.e. constraint to a single valué) and the related abstraction functions are presented.

A comparative analysis of ABE Bachelor of Science programs in European and US Universities.

European Universities are involved in series of great changes regarding teaching and education organization during the last few years. The origin of these changes is the creation of the so-called European Higher Education Area (EHEA), which main target is to harmonize the different University studies throughout Europe. As a consequence, most of the programs of studies in all degrees are suffering changes in order to converge to common structures. Taking advantage of the actual process, some European universities are moving from traditional Agricultural Engineering programs to a more wide discipline named recently as Biosystems Engineering, which is a science- based engineering discipline that integrates engineering science and design with applied biological, environmental and agricultural sciences, broadening in this way the area of application of Engineering sciences not strictly to agricultural sciences, but to the biologic al sciences in general, including the agricultural sciences. This paper presents a comparative study of different Bachelor of Science degrees offered by American and European Universities in the field of Agricultural/Biosystems Engineering. To carry out the analysis 40 programs accredited by ABET in American Universities and 50 European programs. Among other questions, the total number of credits, the number of semesters, the kind of modules and the distribution of subjects in groups (Basic Sciences, Engineering Fundamentals, Agricultural/Biological Sciences, Humanities & Economic Sciences, Applied Agricultural/Biological Engineering and electives) are discussed in the paper. The information provided can be an useful starting point in future definitions of new or renewed degrees with the aim of advancing in internationalization of the programs and helping student’s mobility.

Consultoría en el marco económico-financiero de la empresa

Muchas de las grandes iniciativas empresariales, se ven truncadas por falta de un adecuado análisis económico-financiero. Incluso, muchas grandes ideas no son implantadas correctamente en el primer intento por este motivo, y son otras personas las que consiguen posteriormente el éxito de esas brillantes ideas gracias a una correcta aproximación financiera. Las empresas necesitan definir sus objetivos, establecer las para lograrlos, identificar las personas responsables de su ejecución (sus roles y funciones) y elaborar un plan económico-financiero que recoja el estudio de inversiones necesarias, el análisis de costes, la previsión de ingresos, así como la estrategia financiera más adecuada para la captación de los fondos necesarios para llevar a cabo las acciones programadas. Una vez iniciado el proyecto empresarial, será imprescindible realizar un seguimiento y control de la evolución (integración), tomando las medidas que se estimen oportunas para mantener el rumbo adecuado durante todo el tiempo de actividad. En este trabajo, aplicaremos las metodologías y buenas prácticas de la gestión de proyectos, como marco estructurado que nos permita abordar las principales cuestiones económico-financieras a tener en cuenta a la hora de enfrentarnos a un proyecto empresarial, para contribuir, en la medida de lo posible, a que los emprendedores tengan en cuenta estas cuestiones, facilitando así el desarrollo de negocios, en un difícil entorno económico de crisis como el que actualmente estamos viviendo en España, y animando de esta manera a optar por la iniciativa emprendedora, tratando de minimizar el riesgo en base al contenido. ---ABSTRACT---Lack of adequate economic and financial analysis truncates many of the entrepreneurship and innovation programs. Because of that reason, many great ideas are not even correctly implemented on the first attempt, and the person who finds the proper financial approach, succeed. All the enterprises have to establish clear objectives, actions to accomplish those objectives, assign roles, responsibilities and executive functions to specific people. Elaborate funding plan that contains surveys on necessary investments, cost analysis, estimate the income, liquid assets and also financial strategy suitable for fundraising to finance programmed actions. Once the project has been executed it is essential to monitor and control the development and integration adopting measures accordingly to the needs. This thesis applies methodology and best practice of project management as structured framework for the principal economic and financial issues facing business project. It is necessary contribution to entrepreneurs understanding of business, therefore facilitates business development in such rough environment as Spain is at this moment, and at the same time encourages adopting entrepreneur’s solution as less risky one. This document aims to explore all the economic and financial issues from methodological point of view based on my own professional experience, resulting in helping to understand the importance that economy and finances have in developing adequate corporate strategy. Crisis has highlighted inadequate functionality of many companies. Most popular first symptom is lack of cash flow that deteriorates the company, and results in suspension of payments followed by closing. In other cases, difficulties appear due to poor financial management of committed resources; to be observed in lack of prevision and planning or incorrect basic functionality and operational matters on daily basis. What would be your advice to someone who have magnificent business idea however no knowledge on how to handle finances in order to succeed in initiating and executing the project? Despite of the fact that the central nucleus of this paper is at economics and finances area, all the other concepts and topics given during master will be revived; for example business strategy, consultants abilities, organization and standard processes, among others, are impregnated with knowledge of project management.

Co-simulation Methodologies for Hybrid and Electric Vehicle Dynamics

In recent decades, full electric and hybrid electric vehicles have emerged as an alternative to conventional cars due to a range of factors, including environmental and economic aspects. These vehicles are the result of considerable efforts to seek ways of reducing the use of fossil fuel for vehicle propulsion. Sophisticated technologies such as hybrid and electric powertrains require careful study and optimization. Mathematical models play a key role at this point. Currently, many advanced mathematical analysis tools, as well as computer applications have been built for vehicle simulation purposes. Given the great interest of hybrid and electric powertrains, along with the increasing importance of reliable computer-based models, the author decided to integrate both aspects in the research purpose of this work. Furthermore, this is one of the first final degree projects held at the ETSII (Higher Technical School of Industrial Engineers) that covers the study of hybrid and electric propulsion systems. The present project is based on MBS3D 2.0, a specialized software for the dynamic simulation of multibody systems developed at the UPM Institute of Automobile Research (INSIA). Automobiles are a clear example of complex multibody systems, which are present in nearly every field of engineering. The work presented here benefits from the availability of MBS3D software. This program has proven to be a very efficient tool, with a highly developed underlying mathematical formulation. On this basis, the focus of this project is the extension of MBS3D features in order to be able to perform dynamic simulations of hybrid and electric vehicle models. This requires the joint simulation of the mechanical model of the vehicle, together with the model of the hybrid or electric powertrain. These sub-models belong to completely different physical domains. In fact the powertrain consists of energy storage systems, electrical machines and power electronics, connected to purely mechanical components (wheels, suspension, transmission, clutch…). The challenge today is to create a global vehicle model that is valid for computer simulation. Therefore, the main goal of this project is to apply co-simulation methodologies to a comprehensive model of an electric vehicle, where sub-models from different areas of engineering are coupled. The created electric vehicle (EV) model consists of a separately excited DC electric motor, a Li-ion battery pack, a DC/DC chopper converter and a multibody vehicle model. Co-simulation techniques allow car designers to simulate complex vehicle architectures and behaviors, which are usually difficult to implement in a real environment due to safety and/or economic reasons. In addition, multi-domain computational models help to detect the effects of different driving patterns and parameters and improve the models in a fast and effective way. Automotive designers can greatly benefit from a multidisciplinary approach of new hybrid and electric vehicles. In this case, the global electric vehicle model includes an electrical subsystem and a mechanical subsystem. The electrical subsystem consists of three basic components: electric motor, battery pack and power converter. A modular representation is used for building the dynamic model of the vehicle drivetrain. This means that every component of the drivetrain (submodule) is modeled separately and has its own general dynamic model, with clearly defined inputs and outputs. Then, all the particular submodules are assembled according to the drivetrain configuration and, in this way, the power flow across the components is completely determined. Dynamic models of electrical components are often based on equivalent circuits, where Kirchhoff’s voltage and current laws are applied to draw the algebraic and differential equations. Here, Randles circuit is used for dynamic modeling of the battery and the electric motor is modeled through the analysis of the equivalent circuit of a separately excited DC motor, where the power converter is included. The mechanical subsystem is defined by MBS3D equations. These equations consider the position, velocity and acceleration of all the bodies comprising the vehicle multibody system. MBS3D 2.0 is entirely written in MATLAB and the structure of the program has been thoroughly studied and understood by the author. MBS3D software is adapted according to the requirements of the applied co-simulation method. Some of the core functions are modified, such as integrator and graphics, and several auxiliary functions are added in order to compute the mathematical model of the electrical components. By coupling and co-simulating both subsystems, it is possible to evaluate the dynamic interaction among all the components of the drivetrain. ‘Tight-coupling’ method is used to cosimulate the sub-models. This approach integrates all subsystems simultaneously and the results of the integration are exchanged by function-call. This means that the integration is done jointly for the mechanical and the electrical subsystem, under a single integrator and then, the speed of integration is determined by the slower subsystem. Simulations are then used to show the performance of the developed EV model. However, this project focuses more on the validation of the computational and mathematical tool for electric and hybrid vehicle simulation. For this purpose, a detailed study and comparison of different integrators within the MATLAB environment is done. Consequently, the main efforts are directed towards the implementation of co-simulation techniques in MBS3D software. In this regard, it is not intended to create an extremely precise EV model in terms of real vehicle performance, although an acceptable level of accuracy is achieved. The gap between the EV model and the real system is filled, in a way, by introducing the gas and brake pedals input, which reflects the actual driver behavior. This input is included directly in the differential equations of the model, and determines the amount of current provided to the electric motor. For a separately excited DC motor, the rotor current is proportional to the traction torque delivered to the car wheels. Therefore, as it occurs in the case of real vehicle models, the propulsion torque in the mathematical model is controlled through acceleration and brake pedal commands. The designed transmission system also includes a reduction gear that adapts the torque coming for the motor drive and transfers it. The main contribution of this project is, therefore, the implementation of a new calculation path for the wheel torques, based on performance characteristics and outputs of the electric powertrain model. Originally, the wheel traction and braking torques were input to MBS3D through a vector directly computed by the user in a MATLAB script. Now, they are calculated as a function of the motor current which, in turn, depends on the current provided by the battery pack across the DC/DC chopper converter. The motor and battery currents and voltages are the solutions of the electrical ODE (Ordinary Differential Equation) system coupled to the multibody system. Simultaneously, the outputs of MBS3D model are the position, velocity and acceleration of the vehicle at all times. The motor shaft speed is computed from the output vehicle speed considering the wheel radius, the gear reduction ratio and the transmission efficiency. This motor shaft speed, somehow available from MBS3D model, is then introduced in the differential equations corresponding to the electrical subsystem. In this way, MBS3D and the electrical powertrain model are interconnected and both subsystems exchange values resulting as expected with tight-coupling approach.When programming mathematical models of complex systems, code optimization is a key step in the process. A way to improve the overall performance of the integration, making use of C/C++ as an alternative programming language, is described and implemented. Although this entails a higher computational burden, it leads to important advantages regarding cosimulation speed and stability. In order to do this, it is necessary to integrate MATLAB with another integrated development environment (IDE), where C/C++ code can be generated and executed. In this project, C/C++ files are programmed in Microsoft Visual Studio and the interface between both IDEs is created by building C/C++ MEX file functions. These programs contain functions or subroutines that can be dynamically linked and executed from MATLAB. This process achieves reductions in simulation time up to two orders of magnitude. The tests performed with different integrators, also reveal the stiff character of the differential equations corresponding to the electrical subsystem, and allow the improvement of the cosimulation process. When varying the parameters of the integration and/or the initial conditions of the problem, the solutions of the system of equations show better dynamic response and stability, depending on the integrator used. Several integrators, with variable and non-variable step-size, and for stiff and non-stiff problems are applied to the coupled ODE system. Then, the results are analyzed, compared and discussed. From all the above, the project can be divided into four main parts: 1. Creation of the equation-based electric vehicle model; 2. Programming, simulation and adjustment of the electric vehicle model; 3. Application of co-simulation methodologies to MBS3D and the electric powertrain subsystem; and 4. Code optimization and study of different integrators. Additionally, in order to deeply understand the context of the project, the first chapters include an introduction to basic vehicle dynamics, current classification of hybrid and electric vehicles and an explanation of the involved technologies such as brake energy regeneration, electric and non-electric propulsion systems for EVs and HEVs (hybrid electric vehicles) and their control strategies. Later, the problem of dynamic modeling of hybrid and electric vehicles is discussed. The integrated development environment and the simulation tool are also briefly described. The core chapters include an explanation of the major co-simulation methodologies and how they have been programmed and applied to the electric powertrain model together with the multibody system dynamic model. Finally, the last chapters summarize the main results and conclusions of the project and propose further research topics. In conclusion, co-simulation methodologies are applicable within the integrated development environments MATLAB and Visual Studio, and the simulation tool MBS3D 2.0, where equation-based models of multidisciplinary subsystems, consisting of mechanical and electrical components, are coupled and integrated in a very efficient way.

Hacia un Plano de Directrices Territoriales y Urbanísticas como instrumento esencial para la Habitabilidad Básica

La habitabilidad precaria (HaP) constituye hoy el primer problema mundial del urbanismo, la ordenación del territorio y varias otras disciplinas, como la arquitectura y varias ingenierías que, en conjunto, estructuran e impulsan el sector de la construcción mundial que se centra en atender el alojamiento humano en su diversidad de funciones. En la Conferencia Habitat II, celebrada en 1996 en Estambul, ante el desmesurado crecimiento cuantitativo de la HaP mundial, se planteó la prioridad de prevenir el problema de los nuevos asentamientos precarios: “paliar los problemas relacionados con los asentamientos humanos espontáneos mediante programas y políticas que se anticipen a los asentamientos no planeados”1, sin embargo, tras casi veinte años, aún no existe una herramienta sustantiva y específica que facilite a los políticos responsables de gestionar el desarrollo urbano en ciudades con bajos recursos de países en desarrollo, tomar decisiones que transformen de la forma más eficiente posible el fenómeno de la proliferación de asentamientos informales en una oportunidad de progreso y prosperidad para sus ciudades. La presente tesis parte de la convicción, que trata de fundamentar objetivamente a lo largo del desarrollo de su documentación, de que dicha herramienta fundamental ha de buscarse, a partir de la teoría Habitabilidad Básica, como un soporte esencial con el que reconducir los futuros procesos de ocupación espontánea periurbana. El propósito de la investigación se concreta en caracterizar, y conocer la óptima aplicabilidad, de un instrumento operativo elemental que ayude en la toma de decisiones estratégicas de las autoridades responsables sobre la mejor ubicación de los asentamientos que, hasta la existencia y aplicabilidad de este instrumento, se consideran espontáneos. Asentamientos espontáneos éstos que, en condiciones normales quedarían sujetos durante años a la precariedad mientras que por medio de tal instrumento abandonarían su génesis espontánea para acceder a través de planificación elemental a condiciones de Habitabilidad Básica. La materialización concreta de esta herramienta sería un plano sintético de directrices de ordenación territorial y urbana denominado Plano de Elección del Sitio (PES). Diseñado como un Modelo Teórico Elemental, su aplicación estaría preferentemente orientada a ciudades pequeñas de países en desarrollo que presenten escaso nivel institucional, limitada capacidad económica y técnica, así como ausencia o ineficacia en su planeamiento. A través de un proceso de investigación basado en: la mencionada teoría de la Habitabilidad Básica, la literatura científica de la materia y las experiencias de casos recientes de planificación urbana mediante la aplicación de sistemas de información del suelo, se propone una caracterización y aplicabilidad preliminar de la herramienta. Tras analizar pormenorizadamente sus fortalezas y debilidades y contando con la participación de un grupo de expertos independientes, el trabajo concluye con una nueva caracterización de la herramienta y la reformulación de la hipótesis inicial. ABSTRACT Nowadays, the precarious habitability (PHa) is the main problem of urbanism around the world, land-use planning and several other disciplines such as architecture and different engineering studies that, as a whole, structure and boost the global construction sector which focuses on meeting the Human accommodation in its functional diversity. In the Habitat II Conference in Istanbul in 1996, in light of the excessive quantitative growth of the global PHa, the priority of preventing the problem of new squatter settlements was raised: "to alleviate the problems related to spontaneous human settlements through programs and policies that anticipate unplanned settlements"2, however, after nearly twenty years, there is still no substantive and specific tool to facilitate policy makers to manage urban development for towns with low-income in developing countries, taking decisions that transform as efficiently as possible the phenomenon of the proliferation of informal settlements into an opportunity for progress and prosperity for their cities. This thesis is based on the conviction, which tries to objectively substantiate along the development of its documentation, that this fundamental tool has to be sought from the Basic Habitability theory as an essential support to redirect the future processes of peri-urban spontaneous occupation. The purpose of the research is carried out to characterize, and know the optimum applicability of a basic operational tool to assist in the strategic decisions making of the responsible authorities on the best location of settlements that, until the existence and applicability of this instrument, are considered spontaneous. Spontaneous settlements which, under normal conditions would be subject to the precariousness for years while under that instrument they would abandon their spontaneous genesis for accessing by elemental planning to the Basic Habitability. The concretionary materialization of this tool would be a synthetic guidelines plan of territorial and urban planning called Site Election Plan (SEP). Designed as a Elementary Theoretical Model, its application would preferably be oriented for small towns in developing countries that represent a low institutional, economic and technical limited capacity, as well as the absence or ineffectiveness in their planning. Throughout a research process based on: the aforementioned theory of Basic Habitability, the scientific literature of the subject and the experiences of recent cases of urban planning through the application of soil information systems, characterization and preliminary applicability of the tool is proposed. After attentively analyzing their strengths and weaknesses and with the participation of a group of independent experts, the paper concludes with a new characterization of the tool and the reformulation of the initial hypothesis.

From hematopoiesis to neuropoiesis: Evidence of overlapping genetic programs

It is reasonable to propose that gene expression profiles of purified stem cells could give clues for the molecular mechanisms of stem cell behavior. We took advantage of cDNA subtraction to identify a set of genes selectively expressed in mouse adult hematopoietic stem cells (HSC) as opposed to bone marrow (BM). Analysis of HSC-enriched genes revealed several key regulatory gene candidates, including two novel seven transmembrane (7TM) receptors. Furthermore, by using cDNA microarray techniques we found a large set of HSC-enriched genes that are expressed in mouse neurospheres (a population greatly enriched for neural progenitor cells), but not present in terminally differentiated neural cells. In situ hybridization demonstrated that many of them, including one HSC-enriched 7TM receptor, were selectively expressed in the germinal zones of fetal and adult brain, the regions harboring mouse neural stem cells. We propose that at least some of the transcripts that are selectively and commonly expressed in two or more types of stem cells define a functionally conserved group of genes evolved to participate in basic stem cell functions, including stem cell self-renewal.

Histone H1 overexpressed to high level in tobacco affects certain developmental programs but has limited effect on basal cellular functions.

Histone H1, a major structural component of chromatin fiber, is believed to act as a general repressor of transcription. To investigate in vivo the role of this protein in transcription regulation during development of a multicellular organism, we made transgenic tobacco plants that overexpress the gene for Arabidopsis histone H1. In all plants that overexpressed H1 the total H1-to-DNA ratio in chromatin increased 2.3-2.8 times compared with the physiological level. This was accompanied by 50-100% decrease of native tobacco H1. The phenotypic changes in H1-overexpressing plants ranged from mild to severe perturbations in morphological appearance and flowering. No correlation was observed between the extent of phenotypic change and the variation in the amount of overexpressed H1 or the presence or absence of the native tobacco H1. However, the severe phenotypic changes were correlated with early occurrence during plant growth of cells with abnormally heterochromatinized nuclei. Such cells occurred considerably later in plants with milder changes. Surprisingly, the ability of cells with highly heterochromatinized nuclei to fulfill basic physiological functions, including differentiation, was not markedly hampered. The results support the suggestion that chromatin structural changes dependent on H1 stoichiometry and on the profile of major H1 variants have limited regulatory effect on the activity of genes that control basal cellular functions. However, the H1-mediated chromatin changes can be of much greater importance for the regulation of genes involved in control of specific developmental programs.

Combinatorial control of muscle development by basic helix-loop-helix and MADS-box transcription factors.

Members of the MyoD family of muscle-specific basic helix-loop-helix (bHLH) proteins function within a genetic pathway to control skeletal muscle development. Mutational analyses of these factors suggested that their DNA binding domains mediated interaction with a coregulator required for activation of muscle-specific transcription. Members of the myocyte enhancer binding factor 2 (MEF2) family of MADS-box proteins are expressed at high levels in muscle and neural cells and at lower levels in several other cell types. MEF2 factors are unable to activate muscle gene expression alone, but they potentiate the transcriptional activity of myogenic bHLH proteins. This potentiation appears to be mediated by direct interactions between the DNA binding domains of these different types of transcription factors. Biochemical and genetic evidence suggests that MEF2 factors are the coregulators for myogenic bHLH proteins. The presence of MEF2 and cell-specific bHLH proteins in other cell types raises the possibility that these proteins may also cooperate to regulate other programs of cell-specific gene expression. We present a model to account for such cooperative interactions.

Rede e apoio social entre idosos atendidos em um ambulatório de Geriatria

O objetivo geral deste estudo foi analisar a relação entre a rede e apoio social, satisfação com o apoio social recebido e as variáveis sociodemográficas, de saúde física e mental, dos idosos atendidos em um Ambulatório de Geriatria de um Hospital Geral Terciário do interior paulista. Trata-se de um estudo descritivo, transversal e exploratório, realizado com 98 idosos atendidos no referido ambulatório. Para a coleta de dados, utilizaram-se o Mini Exame do Estado Mental, um questionário de caracterização sociodemográfica e de saúde, a Escala de Depressão Geriátrica (EDG-15), o Índice de Katz, a Escala de Lawton e Brody, a Escala de medida da rede e apoio social do Medical Outcomes Study e a Escala de Satisfação com o Suporte Social. Os aspectos éticos foram respeitados conforme a Resolução 466/2012 do Conselho Nacional de Saúde. A média de idade dos idosos foi de 80,1 anos, 70,4% eram mulheres, 49,0% viúvos; a média de anos de estudo foi 2,3; 24,5% dos idosos residiam com o cônjuge e filhos ou somente com os filhos; a renda familiar média foi de R$1.773,70. Quanto à capacidade funcional, 80,6% eram independentes para as atividades básicas da vida diária e 88,8% eram parcialmente dependentes para as instrumentais. Os idosos possuíam, em média, 5,3 diagnósticos médicos e os sintomas depressivos estiveram presentes para 61,2% deles. Quanto à rede social, o escore total médio foi de 6,4 pessoas para contato na rede, sendo que 36,7% apresentavam médio contato e participação em atividades sociais. Em relação ao apoio social, o maior escore médio foi para a dimensão material (90,2) e o menor para a interação social positiva (81,8); já para a satisfação com o suporte social, 36,7% e 32,7% apresentaram alta e média satisfação, respectivamente. Foi encontrada correlação inversa entre os escores de todas as dimensões da escala de apoio social e os escores da EDG-15, indicando que quanto maior o apoio social em todas as dimensões, menor é a presença de sintomas depressivos e houve diferenças estatisticamente significativas para todas as dimensões, material (p=0,014), afetiva (p=0,026), interação (p=0,011), emocional (p=0,001) e informação (p=0,005); já a correlação entre os escores das dimensões da escala de apoio social e os escores na escala de Lawton e Brody, foi inversa e fraca para as dimensões material (r=-0,157) e informação (r=-0,027), sugerindo que quanto menor a independência para as AIVDs, maior o apoio social nas referidas dimensões, porém, não houve diferença estatisticamente significativa, material (p=0,121) e informação (p=0,789). A correlação entre os escores da EDG-15 e os escores da escala de satisfação com o apoio social, foi inversa e moderada (r=- 0,467), indicando que quanto maior a satisfação com o apoio social, menor a presença de sintomas depressivos, sendo estatisticamente significativa (p=0,000). Evidencia-se a importância de conhecer se os idosos estão inseridos em rede social e se percebem o apoio social para um melhor direcionamento da assistência prestada ao idoso e para o planejamento e formulação de políticas públicas, programas e projetos voltados a essa população

The Pursuit of Balanced Income An Economic Perspective on Wealth

The purpose of this thesis is to determine if households with moderate incomes have the opportunity to acquire pecuniary wealth. In an environment of increasing globalization, labor-eliminating technology, and an overburdened entitlement system, the position of wealth is necessary for households with a penchant for early retirement and particularly for those that will inevitably succumb to involuntary retirement. In these writings, qualitative and quantitative descriptions of wealth are offered; two microeconomic metrics are introduced to identify baseline wealth and to gauge proximity to this value; and strategies are devised to close the gap between these metrics. The construct of the economic intertemporal household budget was used as the basis for this research whereby conventional measures of wealth, i.e. net worth and liquid net worth, have been coupled with historical and empirical household data to define and extrapolate wealth and wealth proximity metrics. The major finding is wealth is a dynamic variable contingent upon consumption level rather than income or saving levels. And because households exercise a greater degree of autonomy over consumption, moderate earners are afforded the same opportunities as high earners. The position of wealth is necessary because it sustains consumption in the event of an unwelcomed retirement and it can assuage reliance on entitlement programs. For the majority of households, wealth is a matter of choice.
