What is new for an old molecule? : Systematic review and recommendations on the use of resveratrol

2011

BackgroundResveratrol is a natural compound suggested to have beneficial health effects. However, people are consuming resveratrol for this reason without having the adequate scientific evidence for its effects in humans. Therefore, scientific valid recommendations concerning the human intake of resveratrol based on available published scientific data are necessary. Such recommendations were formulated after the Resveratrol 2010 conference, held in September 2010 in Helsingør, Denmark.MethodologyLiterature search in databases as PUBMED and ISI Web of Science in combination with manual search was used to answer the following five questions: (1)Can resveratrol be recommended in the prevention…

A Note on added information in the RAS Procedure: reexamination of some evidence

2006

International audience; An example in Miernyk (1977) presented a rather counterintuitive result, namely that introducing accurate exogenous information into an RAS matrix estimating procedure could lead to an estimate that was worse than one generated by RAS using no exogenous information at all. This became an oft-cited black mark against RAS. Miller and Blair (1985) included a different (and small) illustration of the same possibility. It was recently pointed out by one of us that the Miller/Blair numerical results are wrong. For that reason, we decided to reexamine all the empirical evidence we could find on the subject. While figures in both Miernyk and Miller/Blair appear to be wrong, …

Más que flores. Novedades sobre la trayectoria y producción artística del pintor José Romá (Valencia, 1784-1852)

2018

TOURISM, CHARITY, AND FATHERS’ FUNDRAISING STRATEGIES FOR THEIR CHILDREN’S EDUCATION ON THE KENYAN COAST

2018

Increasing empirical evidence shows that child-raising and children’s formal education are influenced by and embedded in cross-border processes and constellations. In Kenya’s South Coast region, widespread support for children’s education is taking place through the long-term relationships local men and women are establishing with tourists from the global North. In this regard, seemingly casual beach encounters initiated by local fathers — who invite western tourist acquaintances to visit their villages and homes — have become a common parental strategy for engaging with tourists who have the potential to become sponsors for their children. In this article we look at the social, economic, a…

Size Clustering in European Carbon Markets

2012

This paper documents empirical evidence of size clustering behavior in the European Carbon Futures Market and analyzes the circumstances under which it happens. Our findings show that carbon trades are concentrated in sizes of one to five contracts and in multiples of five. We have observed the existence of price clustering of prices ending in digits 0 or 5, and we have also proved that more clustered prices have more clustered sizes. Finally, the analysis of the key factors of the size clustering reveals that carbon traders use a reduced number of different trade sizes to simplify their trading process when uncertainty is high, market liquidity is poor, and the desire for opening new posit…

Participation in ICT Development Interventions: Who and How?

2016

The aim of participatory development (PD) in the context of using Information and Communication Technologies (ICT) for development (ICT4D) is to empower underprivileged communities and disadvantaged segments of the stakeholders. The literature on ICT4D is replete with empirical evidence showing that ICT interventions often fail since they are often externally initiated, with very limited involvement from the affected (Heeks, 2002). Clearly, the principles and concepts of PD are relevant to ICT4D. However, we should not consider PD a panacea but need to understand the caveats and processes by which PD happens. Questions to ask include: What are the various challenges in PD? Who are the relev…

Entrepreneurial orientation and new product development performance in SMEs: The mediating role of business model innovation

2021

Abstract In the current business context, entrepreneurial orientation (EO) has been highlighted as key to improving firm performance. Despite the overall positive evidence on the association between EO and firm performance, scholars have stressed the importance of taking into account and properly managing intermediate capabilities. The present study analyses the link between EO and New Product Development (NPD) performance, considering Business Model Innovation (BMI) as a mediating variable. A sample of 400 Spanish SMEs is used to test the proposed research model through structural equation modelling and partial least squares analyses. Results reveal that EO contributes to BMI and NPD perfo…

Virtual Enterprise Simulation Game as an Environment for Collaborative Creativity and Learning

2021

AbstractWhen employees become accustomed to everyday working habits it can prevent them from generating creative ideas. This familiarity takes the forms of mainly collaborating with familiar colleagues, playing roles that develop over years, and solving encountered problems with proven strategies. This chapter considers how a virtual enterprise simulation game (RealGame) can potentially foster digital creativity and collaborative learning. The game simulates a situation where team members take responsibility for managing a virtual manufacturing company and its supply chain. Theoretically, we consider RealGame a facilitating environment for people to collaborate by offering a safe environmen…

THE BASE SYSTEM: A SCHOOL-WIDE POSITIVE BEHAVIOUR SUPPORT TOOL TO FACILITATE EVIDENCE-BASED DIGITAL INTERVENTION PRACTICES

2019

The Positive Behaviour Intervention and Support system is a framework aimed to introduce a change at school-wide level. It promotes a disciplinary system change process, from a reactive punishment- based strategies of specific student misbehaviours to a proactive system, where different behavioural principles such as the modelling and reinforcement of positive prosocial students’ behaviours are applied to improve school values and to create a positive climate. This paper presents the Behavioural Assessment to improve School Environment (BASE) system and the BASE repository. The BASE system supports evidence-based digital intervention practices for stimulating the academic, social, emotional…
