Using a novel style identification procedure, we show that style-shifting is a dynamic strategy commonly used by hedge fund managers. Three quarters of hedge funds shifted their investment styles at least once over the period from January 1994 to December 2013. We perform empirical tests of two hypotheses for the motivations of hedge fund style-shifting, namely backward-looking and forward-looking hypotheses. We find no evidence that style-shifting funds are backward-looking. Instead, we show evidence that managers of style-shifting funds exhibit both style-timing ability and the skill of generating abnormal returns in new styles. The new styles that hedge funds shift to on average outperform their old styles by 0.76% and style-shifting funds on average outperform their new style benchmark by 1.10% over the subsequent 12-month horizon. Finally, we show that small funds, winner funds, and funds with net inflows are more likely to shift styles. This paper was accepted by David Simchi-Levi, finance.

Nowadays the concept and practice about technology management should be thought inside a complex environment in relation with the dynamics information came from other areas. A interdisciplinary concept involved with the dynamic relationship that should be oriented to harness collaboration and integration among the actors and knowledge into digital environment. This perspective reflects the technology management practices and concepts in the context related with other areas, therefore, this point of view is necessary to apply innovated process in order to develop product and service onto Internet environment.  So, this article fills a knowledge gap lived currently in most organizations. Objective: Development a set of directives to be considers during managements practices within organizations and project for developing product and services onto digital environment. This article does not have a proposal to present a method for enabling a kind of innovation solution, but a set of policies and recommendations necessary to achieve the best result in order to develop a product and services via innovation mindset. Method: Review and analysis problems with adaptive comprehension involved with management practices and concept. We present these approaches with and interrelationship environment, which can improve the comprehension analyzing approaches from others areas and body of knowledge.  This mindset is necessary to mitigate many of the problems and improve the innovation idea applied on developing product and services on internet environment. We present this concept of a “management oriented to innovation” as a pattern of  thinking to be argue from managers, used to perform an innovation process and task at various levels and development product and services. A kind of prototype implementation called Innovation that is a process related with a some others areas outside technology . Results : On the basis of these analyses, we propose a policy and guidelines for supporting an innovation initiative is a result of interactions with others areas and concept not necessary inside of technology respects. We develop an mind set architecture for innovation system based on the metaphor of a “innovation” . Finally, we describe this   architecture, with an interface with others concept , for planning and implementing products and services for WEB.  A set of adaptive and interrelationship subjects to insight management practices necessary to improve and follow the tendency of technology applied to new market and business. Conclusion: This article offers multi-level reflections and references to enhance the performance manager skill at manageable practices to deal with developing process to create innovative environment, products and services for digital environment.   Hoje em dia, o conceito e a prática sobre gestão tecnológica devem ser pensados dentro de um ambiente complexo em relação com a informação dinâmica proveniente de outras áreas. Um conceito interdisciplinar envolvido com a relação dinâmica que deve ser orientada para aproveitar a colaboração e a integração entre os actores e o conhecimento no ambiente digital. Esta perspectiva reflecte as práticas e conceitos de gestão tecnológica no contexto relacionado com outras áreas, portanto, este ponto de vista é necessário para aplicar processos inovadores a fim de desenvolver produtos e serviços no ambiente da Internet.  Assim, este artigo preenche uma lacuna de conhecimento vivida actualmente na maioria das organizações. Objectivo: Desenvolver um conjunto de directivas a serem consideradas durante as práticas de gestão dentro das organizações e projectos de desenvolvimento de produtos e serviços para o ambiente digital. Este artigo não tem uma proposta para apresentar um método que permita uma espécie de solução inovadora, mas um conjunto de políticas e recomendações necessárias para alcançar o melhor resultado, a fim de desenvolver um produto e serviços através de uma mentalidade inovadora. Método: Revisão e análise de problemas de compreensão adaptativa envolvidos com práticas e conceitos de gestão. Apresentamos estas abordagens com e ambiente de inter-relação, que podem melhorar a compreensão analisando abordagens de outras áreas e corpo de conhecimento.  Esta mentalidade é necessária para mitigar muitos dos problemas e melhorar a ideia de inovação aplicada no desenvolvimento de produtos e serviços no ambiente da Internet. Apresentamos este conceito de "gestão orientada para a inovação" como um padrão de pensamento a ser defendido pelos gestores, utilizado para realizar um processo e tarefa de inovação a vários níveis e desenvolvimento de produtos e serviços. Uma espécie de implementação de protótipo chamada Inovação que é um processo relacionado com algumas outras áreas fora da tecnologia . Resultados : Com base nestas análises, propomos uma política e orientações para apoiar uma iniciativa de inovação é o resultado de interacções com outras áreas e conceitos não necessários dentro dos aspectos tecnológicos. Desenvolvemos uma arquitectura de conjunto de mentes para um sistema de inovação baseado na metáfora de uma "inovação" . Finalmente, descrevemos esta arquitectura, com uma interface com outros conceitos , para o planeamento e implementação de produtos e serviços para a WEB.  Um conjunto de temas adaptativos e de inter-relação com as práticas de gestão de insight necessárias para melhorar e seguir a tendência da tecnologia aplicada a novos mercados e negócios. Conclusão: Este artigo oferece reflexões e referências a vários níveis para melhorar a capacidade do gestor de desempenho em práticas geríveis para lidar com o desenvolvimento de processos para criar um ambiente inovador, produtos e serviços para o ambiente digital.

Abstract We construct optimal portfolios of mutual funds whose objectives include socially responsible investment (SRI). Comparing portfolios of these funds to those constructed from the broader fund universe reveals the cost of imposing the SRI constraint on investors seeking the highest Sharpe ratio. This SRI cost crucially depends on the investor’s views about asset pricing models and stock-picking skill by fund managers. To an investor who strongly believes in the CAPM and rules out managerial skill, that is, a market index investor, the cost of the SRI constraint is typically just a few basis points per month, measured in certainty-equivalent loss. To an investor who still disallows skill but instead believes to some degree in pricing models that associate higher returns with exposures to size, value, and momentum factors, the SRI constraint is much costlier, typically by at least 30 basis points per month. The SRI constraint imposes large costs on investors whose beliefs allow a substantial amount of fund-manager skill, that is, investors who heavily rely on individual funds’ track records to predict future performance.

Nowadays, sustainability is one of the strategic goals of smart cities. They are the essential solution to creating the sustainable future. On the other hand, the smart city is intended to deal with the problems of energy management. This paper examines the influence of the smart sustainable cities concept on energy management from the labor market perspective. The paper fulfills the research gap about energy manager profession transformation considering smart sustainable city concept. The aim of the paper is to create an up-to-date holistic energy manager skill model with a focus on emerging technologies. The skill model reflects the synergy of two methodological approaches: the theoretical and practical approaches. Descriptive statistics are used to present the labor market research results. It is concluded that the core elements of the smart sustainable city concept have an impact on energy management are sustainability and big data. The labor market research also draws differences in the amount and structure of demand on energy manager skills by countries, but at the same time similar skills requirements are found. The skill model of the energy manager profession is built around several main groups associated with specific knowledge, social skills, and behavior skills. The findings of the present research can contribute to knowledge and practice by applying it in the process of developing energy manager competency models in commercial and non-commercial enterprises as well as in education programs and training courses.
