Modelos log-lineares em tabelas de contingência

Os modelos log-lineares permitem enriquecer bastante a análise e interpretação das tabelas de contingência. Embora a nível teórico a sua importância já tenha sido reconhecida há bastante tempo, a nível da sua aplicação prática só há relativamente pouco tempo é que foi reconhecida, devido, sobretudo, às dificuldades de cálculo que lhe são inerentes e que só se resolveram completamente com o desenvolvimento dos computadores e do software adequado. Neste trabalho apresentam-se os métodos básicos da análise log-linear de tabelas de contingência bidimensionais e tridimensionais.

Continuidade de cuidados numa Unidade de Saúde Familiar : o efeito nos custos

RESUMO - Caracterização do problema: O sistema de saúde português atingiu um patamar de ineficiência tal que urge ser reestruturado de forma a torná-lo sustentável. De forma a atingir este nível de sustentabilidade, uma série de soluções podem ser consideradas das quais destacamos a integração de cuidados. Este conceito exige que os diferentes níveis de saúde sigam um único caminho, trabalhando de forma coordenada e contínua. A integração de cuidados pode ser implementada através de várias tipologias entre as quais se destaca a integração clínica que por sua vez é composta pela continuidade de cuidados. Assim, ao medir a continuidade de cuidados, quantifica-se de certa forma a integração de cuidados. Objetivos: Avaliar o impacto da continuidade de cuidados nos custos. Metodologia: Os dados foram analisados através de estatísticas descritivas para verificar o seu grau de normalidade. Posteriormente foram aplicados testes t-student para analisar a existência de diferenças estatisticamente significativas entre as médias das diferentes variáveis. Foi então estudado o grau de associação entre variáveis através da correlação de spearman. Por fim, foi utilizado o modelo de regressão log-linear para verificar a existência de uma relação entre as várias naturezas de custos e os índices de continuidade. Com base neste modelo foram simulados dois cenários para estimar o impacto da maximização da continuidade de cuidados nas várias naturezas de custos. Conclusões: No geral, verifica-se uma relação muito ligeira entre a continuidade de cuidados e os custos. Mais especificamente, uma relação mais duradoura entre o médico e o doente resulta numa poupança de custos, independentemente da tipologia. Analisando a densidade da relação, observa-se uma relação positiva entre a mesma e os custos totais e o custo com Meios Complementares de Diagnóstico e Terapêutica (MCDT). Contudo verifica-se uma relação médico-doente negativa entre a densidade e os custos com medicamentos e com pessoal. Ao analisar o impacto da continuidade de cuidados nos custos, conclui-se que apenas a duração da relação médico-doente tem um impacto negativo em todas as categorias de custos, exceto o custo com medicamentos. A densidade de cuidados tem um impacto negativo apenas no custo com pessoal, influenciando positivamente as outras categorias de custos. Extrapolando para o nível nacional se o nível de densidade de uma relação fosse maximizado, existiria uma poupança de 0,18 euros, por ano, em custos com pessoal.

Donations of non-financial resources: The motivation and consequences of measuring and accounting for it

This thesis focus on the measurement and accounting of contributions received by nonprofit organizations, as they are a significant component of revenues nowadays. A survey was developed and forward to 38 different NPOs, with the goal of understanding their motivations and what advantages and disadvantages they believe would result if they start to measure and account for all kinds of contributions. They presented many advantages from this practice; however, some are not doing it due to the difficulties in valuing contributions with no market value which would require a higher workload, waste of resources and time to be taken from other important activities.

Measuring the impact of short and lending practices using the DGTW benchmarks

Mutual fund managers increasingly lend their holdings and/or use short sales to generate higher returns for their funds. This project presents a first look into the impact these practices on performance using the performance measures: i) Characteristic Selectivity (CS), the ability of the fund's managers to choose stocks that outperform their benchmarks; ii) Characteristic Timing (CT), the ability of the manager to time the market; iii) and Average Style (AS), the returns from funds systematically holding stocks with certain characteristics. These returns are computed through the DGTW benchmarks. The effect of other variables that have also been shown to impact fund’s returns – total net assets under management, investment styles, turnover and expense ratios – will also be analyzed. I find that managers who use short-sales do not exhibit better stock picking abilities than those who do not, while mutual funds that lend do present higher CS returns. In addition, while lending is not significant for the total performance of a fund, the employment of short-sales and of both short-sales and lending has a negative impact on the fund’s performance.

Measuring social impact: A guideline to implement a tableau de bord

Many impact-seeking organisations cannot measure and demonstrate their social impact because they either lack technical expertise or requisite financial and human resources. This report clarifies the process of social impact measurement to help these organisations engage in social impact measurement practices. It presents a simple guideline to create a measurement approach based on the Tableau de Board. The guideline has been developed through a theoretical revision of best practices in social impact measurement, academic research and the author's individual thoughts and ideas. While a first testing of the approach revealed positive feedback, only future broad-scale testing will demonstrate the approach’s validity and feasibility.

Measuring poverty in Portugal: An absolute approach

The aim of this article is to measure poverty in Portugal from an absolute perspective. We estimated several absolute poverty lines and defined maximum and minimum thresholds. We applied aggregation measures to these thresholds and constructed probit models to assess the effect of some variables on poverty. The intervals obtained contain the poverty lines constructed by other approaches. We got evidence that poverty is positively correlated with the number of people in the household, with living alone; negatively correlated with the number of workers in the household, the share on non-food expenditure and the existence of a heating device at home.

Measuring impact with the social return on investment: the case of the social innovation hub

There is a growing interest in social impact assessment across the private, the public and the nonprofit sector. However, there is still limited academic research produced in this area, particularly in what concerns to the application of the Social Return of Investment (SROI) methodology. The goal of this Work Project is to give an overview of the social impact measurement literature and apply the Social Return on Investment, a flagship methodology to measure impact, to the specific case of the Social Innovation Hub (SIH). The findings suggest that each 1€ invested on the SIH generates 1,21€ in terms of social value. While this value seems very appealing to use, there are some risks in monetizing impact in such way, mainly due to the lack of reliable data available for benchmarking purposes.

Measuring the effects of price movements on private consumption

This paper studies how shocks in the prices of Food, Energy and Financial Assets affect private consumption using a VAR Model. Then, the total effects are broken into direct and indirect effects, using the coefficients taken from the previous model. We use quarterly data for the Portuguese economy from the last 20 years. We found that energy prices and financial assets have a strong connection with consumption, suggesting that the economy may be too exposed to shocks in these markets.
