Behavioral economics, wearable devices, and cooperative games: results from a population-based intervention to increase physical activity

Background: Health care literature supports the development of accessible interventions that integrate behavioral economics, wearable devices, principles of evidence-based behavior change, and community support. However, there are limited real-world examples of large scale, population-based, member-driven reward platforms. Subsequently, a paucity of outcome data exists and health economic effects remain largely theoretical. To complicate matters, an emerging area of research is defining the role of Superusers, the small percentage of unusually engaged digital health participants who may influence other members. Objective: The objective of this preliminary study is to analyze descriptive data from GOODcoins, a self-guided, free-to-consumer engagement and rewards platform incentivizing walking, running and cycling. Registered members accessed the GOODcoins platform through PCs, tablets or mobile devices, and had the opportunity to sync wearables to track activity. Following registration, members were encouraged to join gamified group challenges and compare their progress with that of others. As members met challenge targets, they were rewarded with GOODcoins, which could be redeemed for planet- or people-friendly products. Methods: Outcome data were obtained from the GOODcoins custom SQL database. The reporting period was December 1, 2014 to May 1, 2015. Descriptive self-report data were analyzed using MySQL and MS Excel. Results: The study period includes data from 1298 users who were connected to an exercise tracking device. Females consisted of 52.6% (n=683) of the study population, 33.7% (n=438) were between the ages of 20-29, and 24.8% (n=322) were between the ages of 30-39. 77.5% (n=1006) of connected and active members met daily-recommended physical activity guidelines of 30 minutes, with a total daily average activity of 107 minutes (95% CI 90, 124). Of all connected and active users, 96.1% (n=1248) listed walking as their primary activity. For members who exchanged GOODcoins, the mean balance was 4,000 (95% CI 3850, 4150) at time of redemption, and 50.4% (n=61) of exchanges were for fitness or outdoor products, while 4.1% (n=5) were for food-related items. Participants were most likely to complete challenges when rewards were between 201-300 GOODcoins. Conclusions: The purpose of this study is to form a baseline for future research. Overall, results indicate that challenges and incentives may be effective for connected and active members, and may play a role in achieving daily-recommended activity guidelines. Registrants were typically younger, walking was the primary activity, and rewards were mainly exchanged for fitness or outdoor products. Remaining to be determined is whether members were already physically active at time of registration and are representative of healthy adherers, or were previously inactive and were incentivized to change their behavior. As challenges are gamified, there is an opportunity to investigate the role of superusers and healthy adherers, impacts on behavioral norms, and how cooperative games and incentives can be leveraged across stratified populations. Study limitations and future research agendas are discussed.

Recycling workflows and services through discovery and reuse

Scientific workflows are becoming a valuable tool for scientists to capture and automate e-Science procedures. Their success brings the opportunity to publish, share, reuse and repurpose this explicitly captured knowledge. Within the myGrid project, we have identified key resources that can be shared including complete workflows, fragments of workflows and constituent services. We have examined the alternative ways these can be described by their authors (and subsequent users), and developed a unified descriptive model to support their later discovery. By basing this model on existing standards, we have been able to extend existing Web Service and Semantic Web Service infrastructure whilst still supporting the specific needs of the e-Scientist. myGrid components enable a workflow life-cycle that extends beyond execution, to include discovery of previous relevant designs, reuse of those designs, and subsequent publication. Experience with example groups of scientists indicates that this cycle is valuable. The growing number of workflows and services mean more work is needed to support the user in effective ranking of search results, and to support the repurposing process.

O canal de empréstimos bancários no Brasil: uma evidência microeconômica

The aim of this thesis is to investigate the existence and relevance of the bank-lending channel in Brazil. For that purpose we use balance-sheet data of Brazilian financial institutions, and adopt a methodology based in Kashyap and Stein (2000), who use twostage and panel estimations. We find that restrictive monetary policy – represented by interest rate increases – lower the sensibility of bank lending to the liquidity of its assets. In other words, increases in the interest rate lead to less binding bank liquidity restrictions. Therefore, the existence of a bank-lending channel for the transmission of monetary policy in Brazil is refused.

Hybrid political institutions and governability: the budgetary process in Brazil

In this paper we take a close look at some of the particular pathways by which majoritarian and consensual institutions affect governability. We demonstrate that the mix of majoritarian and consensual institutions found within a country can influence these pathways quite dramatically, such that they produce rather different consequences for governability, even when these pathways are relatively similar in nature. Particularly, we focus on the rules governing the relationship between the President and the Legislature, especially the appropriation of amendments proposed by legislators. In some presidential countries, the president possesses a partial veto (or a line-item veto) which allows him/her to approve or strike appropriations, which legislators introduce in amendments. Concentrating on the case of Brazil, we argue and demonstrate that whether or not the president can use this tool to sustain governing majorities (i.e., to increase governability) depends on the kind of amendment introduced by legislators. One kind, individual amendment, is linked to the majoritarian institution of a powerful presidency and therefore helps to increase governability. A second kind, collective amendment, is linked to consensual institutions and actually does not enhance legislative support for the Executive.

O impacto nos balanços dos intermediários financeiros das ações de política monetária no Brasil

O trabalho busca verificar como as ações da política monetária impactam as instituições financeiras e, por conseguinte o setor real da economia, para tal procura-se também ter o entendimento dos mecanismos de transmissão econômica, com destaque da utilização do canal do crédito. O objetivo principal é analisar o papel das instituições financeiras através de suas ações junto ao restante dos agentes da economia. Como essas instituições são impactadas? Para isso, dividimos a análise em quatro tipos de bancos (comerciais privados, comerciais públicos, investimento e BNDES). Com esse intuito estudamos o impacto da Selic sobre duas classes especificas do balanço financeiro: ativo e patrimônio líquido, sobre o índice de ações IBR-X, assim como o efeito dos choques em componentes macroeconômicos, em específico: produto, investimento e consumo também sobre ativo e patrimônio líquido. Para tal aplicamos a técnica econométrica VAR (Vetor Autoregressivo) para dados mensais da economia brasileira entre 2003 e 2014. Não encontramos nenhum resultado estatisticamente significante sobre o impacto da Selic nos ativos e patrimônio líquido das instituições financeiras utilizadas no estudo, assim como para o impacto nas variáveis macroeconômicas produto, consumo e investimento sobre as mesmas classes contábeis. Para o impacto da Selic sobre o IBR-X encontramos que ao contrário do observado sobre os ativos e patrimônio líquido dos agentes financeiros, um choque da Selic sobre o IBR-X possui um efeito negativo e estatisticamente significante.

Conexões políticas e o desempenho empresarial pós-aquisição no Brasil

Este estudo buscou analisar o efeito das conexões políticas das empresas no nível do Conselho de Administração sobre o desempenho, após o processo de aquisição. Estudos anteriores já identificaram esta relação apontando efeitos, de positivos a neutros das conexões políticas sobre o desempenho, além de influenciar a frequência e o tamanho das operações (BROCKMAN; RUI; ZOU, 2013; LIU; WANG; ZHANG, 2013). Esta pesquisa estende tais análises aplicando o modelo para as empresas brasileiras além de incluir informações sobre o tipo de conexão política para avaliar diferentes impactos. Este estudo foi conduzido dentro do âmbito das empresas compradoras listadas na BM&Bovespa entre os anos de 1999 e 2014, utilizando modelos econométricos de Propensity Score Matching e dados em painel. Partindo da análise de currículos dos conselheiros, foram codificados os diferentes tipos de conexão, como instituições financeiras públicas e de desenvolvimento e agências reguladoras além das formas tradicionais de conexões políticas (FACCIO, 2006). Com base nos resultados foi encontrada uma associação entre as conexões com agências reguladoras e o desempenho pós-aquisição das empresas adquirentes, bem como indícios de uma relação entre os efeitos das conexões com bancos públicos e de desenvolvimento. Não foi possível apontar resultados para as conexões políticas tradicionais

Gestão híbrida em cooperativa de crédito: uma análise a partir do interesse, participação, satisfação e expectativa dos cooperados da COOPERUFPA

The globalization of markets has confirmed for the processes of change in organizations both in structure and in management. This dynamic was also observed in credit unions because they are financial institutions and are under the rules of the Brazil´s Financial System. Given the context of organizational changes in the financial capital has played the traditional management reform is urgent. In organizations credit unions, given its dual purpose, because in the same organizational environment and capitalism coexist cooperative whose logics are antagonistic, but can live through the balance between instrumental rationality and substantive rationality in credit unions. Based on this concept a new form of management should be thought to be able to accommodate the demand of cooperative, community, government and the market. Hybridization has been observed in management practices` COOPERUFPA into dimensions financial, social and solidarity participation with a trend in paradigmatic form of hybrid management, in that it directly or indirectly affect the management decisions in the credit union. The hybrid management is a trend that has been setting the basis for societal transformation, so that credit unions promote actions of welfare oriented cooperative members and the community around the same time that attend the dynamics of market globalization. These actions, in the context of hybrid management should be implemented by COOPERUFPA from the sociability of the remains and the wide diffusion of solidarity culture between cooperative partnership as a way to recover their participation in trade relations, financial and the social collective developement. For the members of COOPERUFPA financial interest is evidenced in greater relevance for the social interest given its dominant relationship as "mere customer" of the credit union, however, the proactive participation of the life of the cooperative credit union is one of its expectative among of participation of to share power in decisions by general meetings. This passivity`s cooperator of the COOPERUFPA in defending the ideals overshadowed the spread of cooperative principles and values of cooperation among them. Thus his conception for COOPERUFPA in the financial dimension, social and solidarity democracy, performed transversely. The COOPERUFPA for not developing an education policy for the cooperation among its members, contributed to a process of collective alienation of cooperative ideals, since the cooperative do not understand the reality that surrounds them as members of an organization whose mission is to social and financial sustainability of its members
