Calidad de vida laboral y liderazgo en trabajadores asistenciales y administrativos en un centro oncológico de la ciudad de Bogotá

El propósito de este estudio fue describir la Calidad de vida laboral (CVL) y el estilo de liderazgo percibido por el personal administrativo/asistencial de un centro oncológico y estimar la asociación entre ellas, considerando las características sociodemográficas. Para ello se aplicó el Cuestionario de Vida profesional [CVP-35] y el Test de Adjetivos de Pitcher [PAT]. En general, los participantes presentan una CVL satisfactoria, caracterizada principalmente por motivación intrínseca, lo cual fue más evidente en el personal asistencial. Respecto al liderazgo, se observó una percepción de ausencia de liderazgo o características poco deseables de éste, lo cual aunque no determina la CVL, si constituye un factor modulador de la misma, las variables sociodemográficas no guardaron relación con la CVL. Por último se resalta la responsabilidad social que tienen los directivos sobre bienestar de los trabajadores de la salud, y consecuentemente sobre la atención al paciente. Se discuten estos hallazgos y lo pertinente de utilizar las categorías emergentes del PAT.

Demarcación teórica del optimismo y la resiliencia en el contexto de capital psicológico.

En este estudio se describe el constructo del Capital Psicológico y se hace el análisis de sus respectivos componentes; enfocándose en los conceptos de Optimismo y Resiliencia, con el fin de encontrar y demarcar teóricamente las diferencias que existen entre estos dos componentes. A consecuencia de la frecuente confusión entre estos dos términos en el ámbito académico, surge el interés de encontrar y analizar diferentes estudios e investigaciones que se hayan hecho hasta el momento, las cuales logren resaltar dichas diferencias, para aplicar este conocimiento a las personas con el fin de brindarles una mejor calidad de vida en el ámbito personal y profesional. La autoeficacia, en contextos organizacionales, hace referencia a la convicción y confianza con la que cuenta un trabajador, sobre sus habilidades para trabajar su motivación, teniendo en cuenta recursos cognitivos y/o cursos de acción necesarios para proyectar y completar exitosamente una prueba específica de su vida. El optimismo, se estudia como aquel estilo de pensamiento explicativo, que carga los eventos positivos a causas internas, continuas y penetrantes, y los eventos negativos a razones externas. Por otro lado, la esperanza es la capacidad de todo ser humano para llevar a cabo acciones que lo orienten a una meta deseada, a través de la propia motivación y el pensamiento seguro y positivo. Por último, la Resiliencia es tener la capacidad de recobrar frente a la adversidad, el fracaso, o incluso cambios efectivos que pueden parecer opresores.

Aquisição por Visão Artificial e Medição Automática de Micro Dureza Vickers

O ensaio de dureza, e mais concretamente o ensaio de micro dureza Vickers, é no universo dos ensaios mecânicos um dos mais utilizados quer seja na indústria, no ensino ou na investigação e desenvolvimento de produto no âmbito das ciências dos materiais. Na grande maioria dos casos, a utilização deste ensaio tem como principal aplicação a caracterização ou controlo da qualidade de fabrico de materiais metálicos. Sendo um ensaio de relativa simplicidade de execução, rapidez e com resultados comparáveis e relacionáveis a outras grandezas físicas das propriedades dos materiais. Contudo, e tratando-se de um método de ensaio cuja intervenção humana é importante, na medição da indentação gerada por penetração mecânica através de um sistema ótico, não deixa de exibir algumas debilidades que daí advêm, como sendo o treino dos técnicos e respetivas acuidades visuais, fenómenos de fadiga visual que afetam os resultados ao longo de um turno de trabalho; ora estes fenómenos afetam a repetibilidade e reprodutibilidade dos resultados obtidos no ensaio. O CINFU possui um micro durómetro Vickers, cuja realização dos ensaios depende de um técnico treinado para a execução do mesmo, apresentando todas as debilidades já mencionadas e que o tornou elegível para o estudo e aplicação de uma solução alternativa. Assim, esta dissertação apresenta o desenvolvimento de uma solução alternativa ao método ótico convencional na medição de micro dureza Vickers. Utilizando programação em LabVIEW da National Instruments, juntamente com as ferramentas de visão computacional (NI Vision), o programa começa por solicitar ao técnico a seleção da câmara para aquisição da imagem digital acoplada ao micro durómetro, seleção do método de ensaio (Força de ensaio); posteriormente o programa efetua o tratamento da imagem (aplicação de filtros para eliminação do ruído de fundo da imagem original), segue-se, por indicação do operador, a zona de interesse (ROI) e por sua vez são identificadas automaticamente os vértices da calote e respetivas distâncias das diagonais geradas concluindo, após aceitação das mesmas, com o respetivo cálculo de micro dureza resultante. Para validação dos resultados foram utilizados blocos-padrão de dureza certificada (CRM), cujos resultados foram satisfatórios, tendo-se obtido um elevado nível de exatidão nas medições efetuadas. Por fim, desenvolveu-se uma folha de cálculo em Excel com a determinação da incerteza associada às medições de micro dureza Vickers. Foram então comparados os resultados nas duas metodologias possíveis, pelo método ótico convencional e pela utilização das ferramentas de visão computacional, tendo-se obtido bons resultados com a solução proposta.

Aggressive incidents inside a Montreal barroom involving patrons, barmaids and bouncers : a micro level examination of routine activity theory

Objectives: This article further examines the phenomenon of aggression inside barrooms by relying on the “bouncer-ethnographer” methodology. The objective is to investigate variations in aggression through time and space according to the role and routine of the target in a Montreal barroom. Thus, it provides an examination of routine activity theory at the micro level: the barroom. Methods: For a period of 258 nights of observation in a Canadian barroom, bouncers completed reports on each intervention and provided specific information regarding what happened, when and where within the venue. In addition, the bouncer-ethnographer compiled field observations and interviews with bar personnel in order to identify aggression hotspots and “rush hours” for three types of actors within barrooms: (a) bouncers, (b) barmaids and (c) patrons. Findings: Three different patterns emerged for shifting hotspots of aggression depending on the target. As the night progresses, aggressive incidents between patrons, towards barmaids and towards bouncers have specific hotspots and rush hours influenced by the specific routine of the target inside the barroom. Implications: The current findings enrich those of previous work by pointing to the relevance of not only examining the environmental characteristics of the barroom, but also the role of the target of aggression. Crime opportunities follow routine activities, even within a specific location on a micro level. Routine activity theory is thus relevant in this context, because as actors in differing roles follow differing routines, as do their patterns of victimization.

De lo micro a lo macro prudencial: Un análisis de la supervisión bancaria desde la econometría espacial

La crisis que se desató en el mercado hipotecario en Estados Unidos en 2008 y que logró propagarse a lo largo de todo sistema financiero, dejó en evidencia el nivel de interconexión que actualmente existe entre las entidades del sector y sus relaciones con el sector productivo, dejando en evidencia la necesidad de identificar y caracterizar el riesgo sistémico inherente al sistema, para que de esta forma las entidades reguladoras busquen una estabilidad tanto individual, como del sistema en general. El presente documento muestra, a través de un modelo que combina el poder informativo de las redes y su adecuación a un modelo espacial auto regresivo (tipo panel), la importancia de incorporar al enfoque micro-prudencial (propuesto en Basilea II), una variable que capture el efecto de estar conectado con otras entidades, realizando así un análisis macro-prudencial (propuesto en Basilea III).

Desenvolvimento, pobreza e meio ambiente no seridó potiguar: um estudo centrado nas micro-regiões do seridó oriental e ocidental

This research work intends to carry out a study focused on the dynamic between development, poverty reduction and conservation of natural resources. To consider this relationship to the region chosen was the micro-region of Eastern and Western Seridó in the state of Rio Grande do Norte. In recent years, several studies (Araújo, 2011; BASTOS, 2009) have pointed out that after a period of economic crisis in its tripodproductive, formed by the activities of farming, cotton farming, mining and faced in the eighties, this region of the State of Rio Grande do Norte, has not only shown signs of economic recovery but also improve their social indicators. On the other hand, studies of desertification as the view of the state of RN (produced in cooperation between the Government of RN and research institutions) and the Sustainable Development Plan of Seridó (ADES, 2000), indicate that there is an ongoing French process of degradation of natural resources that is capable of compromising the ability of sustaining such a system. To verify this reality and likely finding this relationship, this work is adopted for this study, the analysis of evolution of secondary data from official bodies such as the IBGE on HDI, per capita income and other social indicators between 2000 and 2009. Here is another time of the survey analysis of qualitative data collected from interviews with institutions of academic intervention in nature, researchers at the Federal University of Rio Grande do Norte (UFRN) State agencies that address the issue of the Middle Environment in Seridó: Institute for Sustainable Development of the NB (IDEMA) and the Brazilian Institute of Environment and the Amazon (IBAMA) and institutions of direct intervention in the region, as the Agency's Sustainable Development Seridó (adhesive) and the Joint Semi-Arid (ASA). After crossing data from quantitative and qualitative, it was found that the dynamics of the region's economic Seridó Potiguar partially answers the improvement of social indicators of poverty. Contribution by the State in this shared stock transfer income. Regarding the influence of productive restructuring in the region on issues of environment, it is noted that the ceramic tile industry, responsible for the absorption percentage of the population with limited ingress into the urban economy, given the low education, accounts for the increase of susceptibility to the ongoing process of desertification in North Seridó Rio Grande. We conclude finally that the guarantee of increased income, freedom and conservation of natural resources ensures primarily by changing the beliefs and values, especially on the part of the business sector, which use natural resources so predatory, aimed at maintaining their rates of return on investment. And concomitantly, the synchronization between technological change, through the use of new energy sources, and institutional change.

Avaliação dos processos de seleção utilizados nos programas de fomento a inovação nas micro e pequenas empresas da fundação de amparo à pesquisa do Rio Grande do Norte

Technological innovation promotes the generation of economic value by creating a new product, process or organizational management model, being classified as dynamic and multidimensional. Government intervention has the role of acting through government grant programs to foster the integration of innovative processes in small companies, due to the high costs and risks of development, strengthening the country`s economy in this phase. The distribution of this grant is determined by criteria, based especially in subjective judgments, which are based on the beliefs and perceptions about the technological opportunities and market actors involved in the process, being very difficult to measure the probability of success of the project under evaluation. This study aims to identify the most relevant selection criteria that must be inserted in grants programs at Rio Grande do Norte executed by Fundação de Pesquisa do Rio Grande do Norte (FAPERN). Initially, there was a systematization of 18 countries, covering 41 programs in foreign countries and 29 in Brazil. Based on the data collected, we conducted one survey containing four programs of FAPERN (INOVA I, INOVA II , INOVA III and INOVA IV), covering 44 companies and analyzing their responses according to the Likert scale , obtaining the degree of importance given by the respondent to each of the criteria in the questionnaire . As a result, drew up a proposal for new criteria to be used in the next FAPERN´s grants, containing 13 new criteria. It is expected, therefore, to contribute to a better spending of public funds invested in companies subsidized in Brazil

Determinants of child undernutrition in India. A micro-case study to operationalize the Capability Approach

The present research aims at shedding light on the demanding puzzle characterizing the issue of child undernutrition in India. Indeed, the so called ‘Indian development paradox’ identifies the phenomenon according to which higher level of income per capita is recorded alongside a lethargic reduction in the proportion of underweight children aged below three years. Thus, in the time period occurring from 2000 to 2005, real Gross Domestic Production per capita has annually grown at 5.4%, whereas the proportion of children who are underweight has declined from 47% to 46%, a mere one point percent. Such trend opens up the space for discussing the traditionally assumed linkage between income-poverty and undernutrition as well as food intervention as the main focus of policies designed to fight child hunger. Also, it unlocks doors for evaluating the role of an alternative economic approach aiming at explaining undernutrition, such as the Capability Approach. The Capability Approach argues for widening the informational basis to account not only for resources, but also for variables related to liberties, opportunities and autonomy in pursuing what individuals value.The econometric analysis highlights the relevance of including behavioral factors when explaining child undernutrition. In particular, the ability of the mother to move freely in the community without the need of asking permission to her husband or mother-in-law is statistically significant when included in the model, which accounts also for confounding traditional variables, such as economic wealth and food security. Also, focusing on agency, results indicates the necessity of measuring autonomy in different domains and the need of improving the measurement scale for agency data, especially with regards the domain of household duties. Finally, future research is required to investigate policy venues for increasing agency in women and in the communities they live in as viable strategy for reducing the plague of child undernutrition in India.

Micro and Macro essays in Applied Fiscal Policy

This thesis analysis micro and macro aspect of applied fiscal policy issues. The first chapter investigates the extent to which local budget spending composition reacts to fiscal rules variations. I consider the budget of Italian municipalities and exploit specific changes in the Domestic Stability Pact’s rules, to perform a difference-in-discontinuities analysis. The results show that imposing a cap on the total amount of consumption and investment is not as binding as two caps, one for consumption and a different one for investment. More specifically, consumption is triggered by changes in wages and services spending, while investment relies on infrastructure movements. In addition, there is evidence that when an increase in investment is achieved, there is also a higher budget deficit level. The second chapter intends to analyze the extent to which fiscal policy shocks are able to affect macrovariables during business cycle fluctuations, differentiating among three intervention channels: public taxation, consumption and investment. The econometric methodology implemented is a Panel Vector Autoregressive model with a structural characterization. The results show that fiscal shocks have different multipliers in relation to expansion or contraction periods: output does not react during good times while there are significant effects in bad ones. The third chapter evaluates the effects of fiscal policy announcements by the Italian government on the long-term sovereign bond spread of Italy relative to Germany. After collecting data on relevant fiscal policy announcements, we perform an econometric comparative analysis between the three cabinets that followed one another during the period 2009-2013. The results suggest that only fiscal policy announcements made by members of Monti’s cabinet have been effective in influencing significantly the Italian spread in the expected direction, revealing a remarkable credibility gap between Berlusconi’s and Letta’s governments with respect to Monti’s administration.

Banho de clorexidina para prevenção de colonização e infecção por micro-organismos multirresistentes na unidade de transplante de células tronco e hematopoiéticas

Introdução: Infecções relacionadas à assistência de saúde (IRAS) representam hoje um dos principais desafios da qualidade do cuidado do paciente, principalmente em pacientes submetido a transplante de células tronco e hematopoiéticas (TCTH) O banho diário com a clorexidina (CHG) degermante a 2% tem sido proposto principalmente em unidades de terapia intensivas (UTIs) para diminuir a colonização bacteriana do paciente e assim diminuir IRAS. O objetivo deste estudo foi avaliar o impacto do banho com CHG degermante a 2% em unidade de internação de TCTH na incidência de infecção e colonização por patógenos multirresistentes e ainda avaliar seu impacto na sensibilidade das bactérias ao antisséptico. Métodos: Foi realizado um estudo quasi-experimental, com duração de 9 anos, com início em janeiro/2005 até dezembro/2013. A intervenção foi iniciada em agosto de 2009, sendo que os períodos pré e pós-intervenção tiveram duração de 4,5 anos. As taxas de IRAS, infecção por gram-negativos multirresistentes e infecção e colonização por enterococo resistente a vancomicina (VRE) foram avaliadas através de série temporal, para estudar o impacto da intervenção. As concentrações inibitórias mínimas (CIM) das bactérias para a CHG com e sem o inibidor de bomba de efluxo (CCCP) foram avaliadas nos dois períodos. Os genes de resistência a CHG foram estudados por meio da PCR e a clonalidade dos isolados por eletroforese em campo pulsátil. Resultados: Foi observada redução significativa na incidência de infecção e colonização de VRE na unidade no período pós-intervenção (p: 0,001). Essa taxa permaneceu estável em outras UTIs clínicas do hospital. Contudo as taxas de infecção por Gram negativos multirresistentes aumentou nos últimos anos na unidade. Não ocorreu diminuição na taxa de IRAS na unidade. As CIMs testadas de CHG aumentaram nas amostras de VRE e K. pneumoniae após o período de exposição ao antisséptico, com queda importante da CIM após o uso do CCCP, revelando ser a bomba de efluxo, um importante mecanismo de resistência à CHG. As amostras de A. baumannii e P. aeruginosa não apresentaram aumento da CIM após período de exposição à clorexidina. As bombas de efluxo Ade A, B e C estiveram presentes na maioria dos A. baumannii do grupo controle (66%). A bomba cepA foi encontrada em 67% de todas as K. pneumoniae testadas e em 44,5% das P. aeruginosas do grupo pré intervenção. Observamos uma relação positiva entre a presença da CepA nas amostras de K. pneumoniae e a resposta ao CCCP: de todas as 49 amostras CepA positivas 67,3% obtiveram redução do seu MIC em 4 diluições após adição do CCCP. A avaliação de clonalidade demonstrou padrão policlonal das amostras de VRE, K. pneumoniae e A. baumannii avaliadas. Em relação às amostras de P. aeruginosa foi observado que no período pós-intervenção ocorreu predominância de um clone com > 80% semelhança em 10 das 22 amostras avaliadas pelo dendrograma. Conclusões: O banho de clorexidina teve impacto na redução da incidência de infecção e colonização por VRE na unidade de TCTH, e não teve o mesmo impacto nas bactérias gram-negativas. Os mecanismos moleculares de resistência à clorexidina estão intimamente ligados à presença de bomba de efluxo, sendo provavelmente o principal mecanismo de resistência e tolerância das bactérias ao antisséptico

The Long-Term impact of Business Support? - Exploring the Role of Evaluation Timing using Micro Data

The original contribution of this work is threefold. Firstly, this thesis develops a critical perspective on current evaluation practice of business support, with focus on the timing of evaluation. The general time frame applied for business support policy evaluation is limited to one to two, seldom three years post intervention. This is despite calls for long-term impact studies by various authors, concerned about time lags before effects are fully realised. This desire for long-term evaluation opposes the requirements by policy-makers and funders, seeking quick results. Also, current ‘best practice’ frameworks do not refer to timing or its implications, and data availability affects the ability to undertake long-term evaluation. Secondly, this thesis provides methodological value for follow-up and similar studies by using data linking of scheme-beneficiary data with official performance datasets. Thus data availability problems are avoided through the use of secondary data. Thirdly, this thesis builds the evidence, through the application of a longitudinal impact study of small business support in England, covering seven years of post intervention data. This illustrates the variability of results for different evaluation periods, and the value in using multiple years of data for a robust understanding of support impact. For survival, impact of assistance is found to be immediate, but limited. Concerning growth, significant impact centres on a two to three year period post intervention for the linear selection and quantile regression models – positive for employment and turnover, negative for productivity. Attribution of impact may present a problem for subsequent periods. The results clearly support the argument for the use of longitudinal data and analysis, and a greater appreciation by evaluators of the factor time. This analysis recommends a time frame of four to five years post intervention for soft business support evaluation.
