Cuidados informais : os idosos em situação de dependência em Portugal

RESUMO - Enquadramento: As mudanças demográficas e na estrutura social das famílias precipitaram reformas das políticas dos cuidados de longa duração da população idosa no continente Europeu. Após um período em que as mulheres assumiam o papel de principais cuidadoras dos membros mais idosos, o aumento da sua inclusão no mercado de trabalho, assim como o envelhecimento geral da população introduziu mudanças no enquadramento dos cuidados a idosos. Estas mudanças têm particular impacte nos países da Europa do Sul, visto que tradicionalmente o cuidado a idosos é prestado maioritariamente pelo sector informal. Finalidade/objectivos: O presente estudo tem como finalidade conhecer as características dos cuidadores informais e dos idosos dependentes em Portugal. Definiram-se três objectivos principais. O primeiro é compreender a realidade demográfica, de saúde e dependência funcional dos idosos alvo de cuidados informais em Portugal. Em segundo pretende-se conhecer a situação actual dos prestadores informais de cuidados de longa duração em Portugal. Em terceiro, discutem-se os aspectos que mais influenciam a acessibilidade a cuidados informais entre os idosos dependentes em Portugal. Metodologia: Para concretizar estes objectivos, para além de se proceder a uma sistematização bibliográfica da literatura mais relevante nesta área, recorre-se à análise descritiva e regressão logística binária. Utilizando os dados do inquérito Survey of Health, Ageing and Retirement in Europe descreve-se a realidade nacional dos idosos dependentes e seus cuidadores informais e estimam-se modelos de acessibilidade aos cuidados informais em Portugal. Resultados/conclusões: Este estudo contribui para o conhecimento de três aspectos fundamentais sobre os cuidados informais em Portugal: o primeiro prende-se com a quantificação da realidade nacional dos idosos dependentes em Portugal; o segundo relaciona-se com a quantificação da situação portuguesa dos cuidadores informais; e, por último, estima-se modelos explicativos sobre a acessibilidade a cuidados informais. Para além da quantificação da realidade nacional, o principal contributo deste trabalho reside na demonstração de que o actual modelo de prestação de cuidados (baseado nos cuidados informais prestados por membros da família) deixa de fora uma parte significativa dos idosos dependentes. Na verdade, este estudo demonstra que uma parte significativa dos idosos não tem acesso a cuidados e que, embora sejam os elementos da família que maioritariamente prestam os cuidados informais, esse facto, por si só, não explica o acesso aos cuidados.

DYNAMOD – A dynamic agent based modelling framework for digital businesses

Digital Businesses have become a major driver for economic growth and have seen an explosion of new startups. At the same time, it also includes mature enterprises that have become global giants in a relatively short period of time. Digital Businesses have unique characteristics that make the running and management of a Digital Business much different from traditional offline businesses. Digital businesses respond to online users who are highly interconnected and networked. This enables a rapid flow of word of mouth, at a pace far greater than ever envisioned when dealing with traditional products and services. The relatively low cost of incremental user addition has led to a variety of innovation in pricing of digital products, including various forms of free and freemium pricing models. This thesis explores the unique characteristics and complexities of Digital Businesses and its implications on the design of Digital Business Models and Revenue Models. The thesis proposes an Agent Based Modeling Framework that can be used to develop Simulation Models that simulate the complex dynamics of Digital Businesses and the user interactions between users of a digital product. Such Simulation models can be used for a variety of purposes such as simple forecasting, analysing the impact of market disturbances, analysing the impact of changes in pricing models and optimising the pricing for maximum revenue generation or a balance between growth in usage and revenue generation. These models can be developed for a mature enterprise with a large historical record of user growth rate as well as for early stage enterprises without much historical data. Through three case studies, the thesis demonstrates the applicability of the Framework and its potential applications.

Can a lemon based Sagres product attract consumers that don't drink beer?

The purpose of this project is to understand if the brand Sagres is damaging the product Sagres Radler. The beer market in Portugal was studied and focus groups were used to perceive the impact of the brand in the product. The mother brand is bringing the beer association into a product designed to engage people that don’t like beer. With the insights, a new proposal was drawn and tested. Although it was not possible to prove that the new concept is better for the population, there are strong indications that the brand isn’t enabling the achievement of the proposed target.

The quest for growth in the German organic food retail market: Historical trends, current strategies, and future outlook

This paper aims to provide strategies for the organic supermarket chain “Alnatura” to shape the demand and its market share of the organic food & beverage (F&B) market in Germany within the next five years. Through the historic evolution and the current market assessment of Germany, compared to a benchmark country (US), as well as prospective trends in Germany, reasons and opportunities for market growth are evaluated. In addition, an industry attractiveness, competitor and company analysis is executed. Based on those findings and a conducted survey, suggestions to adjust Alnatura´s current business strategies are deduced and finally examined on its risk and feasibility.

Value creation in the nursing home real estate investment market - A case study

The underlying thesis examines the value drivers of direct investments in nursing home real estate in Germany. A survey among investors and operators is conducted in order to identify significant value drivers. Moreover, based on survey results, a framework for assessing German nursing home real estate is developed. This is applied in a case-study about the set-up of a nursing home value-add fund which will demonstrate the value creation process of redeveloping an existing nursing home real estate portfolio. Through a concluding analysis the sources of value creation, sensitivities and future prospects of direct investing into German nursing home real estate are concluded.

An agent based architecture to support monitoring in plug and produce manufacturing systems using knowledge extraction

In recent years a set of production paradigms were proposed in order to capacitate manufacturers to meet the new market requirements, such as the shift in demand for highly customized products resulting in a shorter product life cycle, rather than the traditional mass production standardized consumables. These new paradigms advocate solutions capable of facing these requirements, empowering manufacturing systems with a high capacity to adapt along with elevated flexibility and robustness in order to deal with disturbances, like unexpected orders or malfunctions. Evolvable Production Systems propose a solution based on the usage of modularity and self-organization with a fine granularity level, supporting pluggability and in this way allowing companies to add and/or remove components during execution without any extra re-programming effort. However, current monitoring software was not designed to fully support these characteristics, being commonly based on centralized SCADA systems, incapable of re-adapting during execution to the unexpected plugging/unplugging of devices nor changes in the entire system’s topology. Considering these aspects, the work developed for this thesis encompasses a fully distributed agent-based architecture, capable of performing knowledge extraction at different levels of abstraction without sacrificing the capacity to add and/or remove monitoring entities, responsible for data extraction and analysis, during runtime.

Microstructural changes befor macroeconomic announcements: Predictability of economic surprises in the U.S. market

Flow of new information is what produces price changes, understanding if the market is unbalanced is fundamental to know how much inventory market makers should keep during an important economic release. After identifying which economic indicators impact the S&P and 10 year Treasuries. The Volume Synchronized Probability of Information-Based Trading (VPIN) will be used as a predictability measure. The results point to some predictability power over economic surprises of the VPIN metric, mainly when calculated using the S&P. This finding appears to be supported when analysing depth imbalance before economic releases. Inferior results were achieved when using treasuries. The final aim of this study is to fill the gap between microstructural changes and macroeconomic events.
