Forecasts of relative performance in tournaments: Evidence from the field

This paper uses a field experiment to investigate the quality of individuals’ forecasts of relative performance in tournaments. We ask players in luck-based (poker) and skill-based (chess) tournaments to make point forecasts of rank. The main finding of the paper is that players’ forecasts in both types of tournaments are biased towards overestimation of relative performance. However, the size of the biases found is not as large as the ones often reported in the psychology literature. We also find support for the “unskilled and unaware hypothesis” in chess: high skilled chess players make better forecasts than low skilled chess players. Finally, we find that chess players’ forecasts of relative performance are not efficient.

O Fim da Transgressão na Performance Social e Artística

A presente dissertação intitulada “O fim da transgressão na performance social e artística” pretende descrever e enquadrar numa perspectiva teórica a contemporaneidade destas duas dimensões, problematizando-as, de forma a indagar um estado de posição argumentativa coerente e actual sobre as mesmas. “O fim da transgressão” anuncia que o conceito de transgressão será aqui analisado e aprofundado tendo presentes as perspectivas de vários autores, compreendendo o seu surgimento, as variantes e influências que o conceito pode tomar e ser influenciado. Este conceito é inserido em possíveis interpretações da sociedade, desde escalas macro sociais a casos particulares, e depois enumerado num esquema transversal da história da performance artística. De modo que a correlação entre o estado da sociedade influencia o estado da arte, e vice-versa, reflectindo-se sobre as suas regras e lei. A argumentação apresentada é um estudo da transgressão na reflexão da moral e da psicologia da massa social, inquirindo o normativo, o desvanecimento dos valores considerados ultrapassados e a biotecnologia vigente desde o humanismo, passando pelo pós-humanismo no devir do homem-máquina e enquadrando o metahumanismo da segunda década do século XX. Problematiza-se a viabilidade da transgressão ou norma num mundo de consumismo espectacular, de hedonismo personalizado e narcisismo massivo.

O processo de envelhecimento numa população adulta com défice intelectual e desenvolvimental, DID: "perfil de funcionalidade"

RESUMO: O envelhecimento demográfico da população associado aos avanços científicos fezcom que esse fenómeno se estendesse à população com dificuldade intelectual e desenvolvimental. O processo de envelhecimento na população com DID acarreta novas formas de dependência, carências e perdas que, associadas à deficiência assumem contornos de dupla vulnerabilidade: ser idoso e ser deficiente. Objetivos, deste estudo foram caraterizar o perfil de funcionalidade numa população adulta com DID e apurar de que forma é que os aspectos sociodemográficos, condição de saúde, estado nutricional e redes socias de apoio interferem nesse perfil. Metodologia, aplicou-se a Escala de Comportamento Adaptativo versão Portuguesa a uma amostra de 40 indivíduos com DID, procedeu-se ao estudo da relação entre os vários domínios da escala e os diferentes aspetos anteriormente mencionados. Resultados, apontam para o facto, de tal como na população em geral, o processo de envelhecimento desta população variar em função do estado de saúde, das limitações da própria deficiência e da existência de sistema de apoios mais do que a idade cronológica. Conclusão, o envelhecimento da população com DID é um fenómeno recente sendo por isso importante ter um conhecimento mais aprofundado das suas caraterísticas e necessidades. A ECAP revelou ser um instrumento que permite avaliar o desempenho funcional desta população distinguindo-a da restante população idosa contribuindo assim, para o desenvolvimento de planos e programas de intervenção mais adequados.-------------ABSTRACT: The aging of the population associated with scientific advances made this phenomenon extend to the population with intellectual and developmental difficulties. The aging process in people with DID entails new forms of dependence, shortages and losses, associated with disability take contours of double vulnerability: being elderly and being disabled. Objectives, in this study were to characterize the profile functionality in an adult population with DID and determine how it is that their sociodemographic characteristics, health status, nutritional status and members support networks affect this listing. Methodology, was applied the adaptive behavior scale Portuguese version to a sample of 40 individuals with DID, we proceeded to study the relationship between the various domains of the scale and the different aspects mentioned above. Results, point to the fact, such as in the general population, the aging of the population vary depending on the state of health, of the limitations of the disability itself and the existence of support rather than chronological age system. Conclusion, an aging population with DID is a recent phenomenon and is therefore important to have a broader knowledge of their characteristics and needs. ECAP has proved to be a tool to evaluate the functional performance of this population distinguished from the remaining elderly population, thus contributing to the development of plans and most appropriate intervention programs. aging, adaptive behavior scale.

Hole cleaning performance monitoring during the drilling of directional wells

During drilling operation, cuttings are produced downhole and must be removed to avoid issues which can lead to Non Productive Time (NPT). Most of stuck pipe and then Bottom-Hole Assembly (BHA) lost events are hole cleaned related. There are many parameters which help determine hole cleaning conditions, but a proper selection of the key parameters will facilitate monitoring hole cleaning conditions and interventions. The aim of Hole Cleaning Monitoring is to keep track of borehole conditions including hole cleaning efficiency and wellbore stability issues during drilling operations. Adequate hole cleaning is the one of the main concerns in the underbalanced drilling operations especially for directional and horizontal wells. This dissertation addresses some hole cleaning fundamentals which will act as the basis for recommendation practice during drilling operations. Understand how parameters such as Flowrate, Rotation per Minute (RPM), Rate of Penetration (ROP) and Mud Weight are useful to improve the hole cleaning performance and how Equivalent Circulate Density (ECD), Torque & Drag (T&D) and Cuttings Volumes coming from downhole help to indicate how clean and stable the well is. For case study, hole cleaning performance or cuttings volume removal monitoring, will be based on real-time measurements of the cuttings volume removal from downhole at certain time, taking into account Flowrate, RPM, ROP and Drilling fluid or Mud properties, and then will be plotted and compared to the volume being drilled expected. ECD monitoring will dictate hole stability conditions and T&D and Cuttings Volume coming from downhole monitoring will dictate how clean the well is. T&D Modeling Software provide theoretical calculated T&D trends which will be plotted and compared to the real-time measurements. It will use the measured hookloads to perform a back-calculation of friction factors along the wellbore.

Estudo orgânico-funcional das entidades tutelares da Agricultura (1918-2013): Uma contribuição para o Ficheiro Nacional de Autoridades Arquivísticas (FNAA)

O objeto de estudo desta dissertação são as entidades ministeriais tutelares da agricultura entre 1918 e 2013. As razões desta escolha prendem-se com o facto de estas serem entidades cuja produção documental e património arquivístico são fundamentais para a compreensão e estudo do sector primário da economia nacional durante todo o século XX até ao momento presente. Foi primeiramente realizado o estudo orgânico-funcional das entidades ministeriais, efetuado com base na sua legislação de criação, remodelação, fusão e extinção e que possibilitou a identificação da quantidade, natureza, duração e estrutura de cada uma delas. Tal estudo permitiu a identificação de 17 entidades ministeriais e a confirmação de que todas estas entidades reuniam as condições necessárias para serem consideradas produtoras de fundos documentais da Administração Pública Portuguesa, logo que todas podiam ser objeto de criação de Registos de Autoridade Arquivística. Os estudos orgânico-funcionais realizados foram então canalizados para a criação de um total de 17 Registos de Autoridade Arquivística, feitos com base no modelo do Ficheiro Nacional de Autoridades Arquivísticas (FNAA) e seguindo os princípios estabelecidos pelas normas internacionais do Conselho Internacional de Arquivos (ISAAR-CPF), bem como os estabelecidos pelas Orientações para a Descrição Arquivística. Ao utilizar o modelo do FNAA, a presente proposta tem como objetivos: identificar univocamente cada uma das entidades ministeriais estudadas enquanto autoridades arquivísticas produtoras de fundos documentais; identificar e mapear o seu percurso institucional e administrativo; facilitar a reunião intelectual da documentação produzida por estas entidades. A proposta apresentada nesta dissertação pretendeu assim articular o paradigma custodial atual, com as possibilidades trazidas pela mudança para um paradigma pós-custodial e potenciadas pelas tecnologias de informação (das quais o FNAA constitui o modelo nacional atualmente na vanguarda). Com isto espera-se poder contribuir para o módulo de entidades produtoras (MEP) do FNAA, nomeadamente na sua vertente de criação de registos para organizações (extintas) da Administração Pública.

Thermal performance of cool facades: evaluation by Infrared Thermography

High reflective paints (cool paints) are used on flat roofs to reduce heat gains from the incidence of solar radiation and thus improve the thermal comfort and energy efficiency of buildings, especially in summer periods. Given the application potential of these paints on vertical surfaces, a research study has been developed to evaluate the thermal performance of reflective paints on walls under real exposure conditions. Accordingly, different reflective paints have been applied as the final coating of an ETICS type solution, on the facades of a full scale experimental cell built at LNEC campus. For being applied in an ETICS system a paint has to fulfill several requirements, whether aesthetic or functional (such as the adhesion between the coating layers or the durability of the insulation), essential for its efficient performance. Since this construction coating system is subject to a prolonged sun exposure, various problems may arise, such as paint degradation or deterioration of the thermal insulation properties, particularly when dark colors are applied. To evaluate the thermal performance of the chosen paints, the method of non-destructive analysis by Infrared Thermography was used. Thermography allows knowing the temperature distribution of facades by measuring the radiation emitted by their surfaces. To complement the thermographic diagnosis, thermocouples were placed between the insulation and the paint system of the experimental cell. Additional laboratory tests allowed the characterization of the optical properties (reflectance and emittance) of the different reflective paints used in this study. The comparative analysis of the thermal performance of reflective and conventional paints revealed that the reflective paint allows a reduction of the facade surface temperature, reducing the risk of loss of insulating properties of the ETICS system and thus ensuring its longevity and functionality. The color of the paint used affects, naturally, the reflective ability of the surface and may have an important role in energy balance of the building. This paper also showed the potential of infrared thermography in the evaluation of the thermal performance of reflective paints.

Influence of Lean and Green on supply chain performance: an interpretive structural modelling model

This work aims to identify and rank a set of Lean and Green practices and supply chain performance measures on which managers should focus to achieve competitiveness and improve the performance of automotive supply chains. The identification of the contextual relationships among the suggested practices and measures, was performed through literature review. Their ranking was done by interviews with professionals from the automotive industry and academics with wide knowledge on the subject. The methodology of interpretive structural modelling (ISM) is a useful methodology to identify inter relationships among Lean and Green practices and supply chain performance measures and to support the evaluation of automotive supply chain performance. Using the ISM methodology, the variables under study were clustered according to their driving power and dependence power. The ISM methodology was proposed to be used in this work. The model intends to provide a better understanding of the variables that have more influence (driving variables), the others and those which are most influenced (dependent variables) by others. The information provided by this model is strategic for managers who can use it to identify which variables they should focus on in order to have competitive supply chains.

Fatores de risco de queda em idosos institucionalizados

RESUMO: A ocorrência de queda no idoso constitui uma preocupação no que se refere à morbilidade e mortalidade, sendo um fator a ter em conta no atual envelhecimento populacional. Torna-se assim perentório analisar quais os fatores de risco de forma a intervir de forma preventiva. Objetivo: Este estudo pretendeu identificar os fatores de risco associados à ocorrência de queda em idosos institucionalizados na Mansão de Santa Maria de Marvila, em Lisboa. Método: O estudo realizado foi observacional, longitudinal, prospetivo e analítico. Os idosos foram avaliados num momento inicial no que respeita aos fatores de risco descritos na literatura e posteriormente foi observada a ocorrência ou ausência de queda durante seis meses consecutivos. Resultados: Dos 45 idosos, 20 sofreram ocorrência de queda e destes 13 sofreram quedas múltiplas. Dos fatores de risco analisados, encontrou-se associação entre a ocorrência de queda e o historial de queda, o medo de cair, o défice cognitivo e o défice funcional e o desempenho na marcha. Conclusão: O número de quedas ocorridas foi elevado, destacando-se a ocorrência frequente de quedas múltiplas por residente. Concluiu-se que os fatores de risco de queda nesta população são múltiplos, sendo que os recursos das instituições devem ser orientados para os mesmos de forma a prevenir a queda.------------ABSTRACT:The occurrence of falls in the elderly is a concern regarding morbidity and mortality, being a factor to be taken into account in the current population aging. It thus becomes urgent to analyze which are the risk factors in order to intervene preventively. Objective: This study aimed to identify risk factors associated with the occurrence of falls in institutionalized elderly at Mansão Santa Maria de Marvila in Lisbon. Method: The study was observational, longitudinal, prospective and analytical. Risk factors described in the literature were evaluated in an initial phase and subsequently the occurrence or absence of falling was observed for six consecutive months.Results: Of the 45 subjects, 20 had sustained occurrence of falls and of these 13 had suffered multiple falls. Of the risk factors examined, there was an association between the occurrence of fall and a history of falling, fear of falling, cognitive impairment and functional impairment and gait performance. Conclusion: The number of falls occurred was high, especially the frequent occurrence of multiple falls per resident. It was concluded that the risk factors of falls in this population are multiple, and the resources of the institutions should be directed to them to prevent the falls.

Construction of Lean and Green indexes to measure companies’ performance

The demand for costs and time reductions in companies’ processes, in order to increase efficiency, leads companies to seek innovative management paradigms to support their needs for growth and continuous improvement. The Lean paradigm has great relevance in companies’ need for waste reduction, particularly in manufacturing companies. On the other hand the demand of companies for waste reduction has gained a new dimension not only at the material level, but also at the environmental level with the introduction of the Green paradigm. As such, manufacturing companies have been adopting practices that reduce the impact of their activities on the environment. Although nowadays many manufacturing companies already implement waste reduction practices related to Lean and Green paradigms, many of them are unable to understand specifically if their efforts are enough for the application of these practices to be successful or even if their actual performance in implementing Lean or Green practices reflects the self-assessment that they have of themselves. Thus, besides the study of the development of Lean and Green paradigms in recent years, the present dissertation has the important objective of the construction of two indexes (the Lean Index and the Green Index) enabling the measurement of the performance of Portuguese manufacturing companies relating the implementation of Lean and Green practices. The data used to create the Lean and Green indexes where obtained from the implementation of the European Manufacturing Survey 2012 in Portugal. The survey questions related to the implementation of Lean and Green practices are used as variables in the development of the model for the two indexes. For the construction of representative expressions of Lean Index and Green Index it was applied the Factorial Analysis for assigning the variables weights and aggregation.
