How do remuneration committees affect corporate social responsibility disclosure? empirical evidence from an international perspective
2022
The main goal of this study is to analyze whether the existence of remuneration committees tend to disclose more corporate social responsibility (CSR) information. In addition, we test the moderating role played by the proportion of independent directors on boards of directors with the relationship between the constitution of remuneration committees and CSR disclosure. Previous research does not appear to have addressed these questions. The research questions proposed are tested using an international sample of 28,610 listed companies, and we took into consideration information on industrial companies from the Middle East, developed Asian and Pacific countries, both emerging and developed E…
Developing and Validating a Behavioural Model of Cyberinsurance Adoption
2021
Business disruption from cyberattacks is a growing concern, yet cyberinsurance uptake remains low. Using an online behavioural economics experiment with 4800 participants across four EU countries, this study tests a predictive model of cyberinsurance adoption, incorporating elements of Protection Motivation Theory (PMT) and the Theory of Planned Behaviour (TPB) as well as factors in relation to risk propensity and price. During the experiment, participants were given the opportunity to purchase different cybersecurity measures and cyberinsurance products before performing an online task. Participants likelihood of suffering a cyberattack was dependent upon their adoption of cybersecurity me…
Impact of Wind Electricity Forecasts on Bidding Strategies
2017
The change in the generation mix from conventional electricity sources to renewables has important implications for bidding behaviour and may have an impact on prices. The main goal of this work is to discover the role played by expected wind production, together with other relevant factors, in explaining the day-ahead market price through a data panel model. The Spanish market, given the huge increase in wind generation observed in the last decade, has been chosen for this study as a paradigmatic example. The results obtained suggest that wind power forecasts are a new key determinant for supply market participants when bidding in the day-ahead market. We also provide a conservative quanti…
Recurrent central giant cell granuloma in the mandible: surgical treatment and dental implant restoration.
2007
Central giant cell granuloma is an uncommon benign intraosseus lesion of jaws. Traditional treatment has been local curettage, although aggressive sub-types have a high tendency to recur. This patient report describes a recurrent central giant cell granuloma involving the body of the mandible in a 48-year-old-woman. Initial treatment of lesion consisted of curettage and peripheral ostectomy. When recurrence was detected one year later, an en bloc resection and defect regeneration with a composite bone graft of autogenous bone, xenograft, and autologous platelet-rich plasma was carried out. Adequate new bone formation was observed during follow-up of 24 months. Two dental implants were place…
Unmanned aerial vehicle application for mapping individual plants: the case of the Nebrodi beech forest
2015
The UAVs (Unmanned Aerial Vehicles) are small unmanned aircraft remote controlled electronically, commonly called "drones", which can serve as a vector to carry one or more sensors for georeferenced digital image capture. The development of these platforms is begun in the 50s for military purposes and is today successfully applied in the civil sphere with levels of technology and higher performance. It is a remote sensing technique to the scale of detail that allows for monitoring, measuring and mapping of several environmental data in a short time. The use of NDIR sensors (Non Dispersive Infrared sensor) for the detection of plant cover, allows discriminating plant species, mapping individ…
The Diversification of Sicilian Farms: A Way to Sustainable Rural Development
2021
Rural areas still suffer from a lack of sustainable development, and the diversification of farms may be a step in the right direction. The paper provides a detailed picture of the diversification of Sicilian farms into tourism services. Specifically, we propose a simple indicator of localization intensity of agritourism farms and explore their spatial distribution at municipality level. Our study highlights that Sicilian farms rarely diversify into tourism services, despite being situated in attractive areas. That said, some significant spatial clusters of municipalities where agritourism farms are highly concentrated do emerge from the study.
Consistent phenological shifts in the making of a biodiversity hotspot: the Cape flora
2011
Abstract Background The best documented survival responses of organisms to past climate change on short (glacial-interglacial) timescales are distributional shifts. Despite ample evidence on such timescales for local adaptations of populations at specific sites, the long-term impacts of such changes on evolutionary significant units in response to past climatic change have been little documented. Here we use phylogenies to reconstruct changes in distribution and flowering ecology of the Cape flora - South Africa's biodiversity hotspot - through a period of past (Neogene and Quaternary) changes in the seasonality of rainfall over a timescale of several million years. Results Forty-three dist…
The phenology of submerged macrophytes from Mediterranean wetlands as a sentinel of climate change = La fenologia dels macròfits submergits d'aiguamo…
2018
L’estudi de la fenologia, i.e. la temporització dels esdeveniments biològics recurrents, s’està usant per detectar els efectes del canvi climàtic sobre els organismes. Encara que els macròfits submergits exerceixen una funció clau en l’estructuració dels ecosistemes soms, hi ha poca informació sobre la seua fenologia. Aquesta tesi presenta les primeres dades (de 2014 a 2016) d’un esperable estudi a llarg termini. Els objectius principals son (i) establir la base metodològica per a l’estudi fenològic dels macròfits submergits, (ii) descriure la fenologia reproductiva de 6 espècies (Chara hispida, C. aspera, C. canescens, Nitella hyalina, Stuckenia pectinata i Utricularia australis) en dos ll…
Global Perspective on Marital Satisfaction
2020
Across the world, millions of couples get married each year. One of the strongest predictors of whether partners will remain in their relationship is their reported satisfaction. Marital satisfaction is commonly found to be a key predictor of both individual and relational well-being. Despite its importance in predicting relationship longevity, there are relatively few empirical research studies examining predictors of marital satisfaction outside of a Western context. To address this gap in the literature and complete the existing knowledge about global predictors of marital satisfaction, we used an open-access database of self-reported assessments of self-reported marital satisfaction wit…
Measuring the Economic, Environmental, and Social Sustainability of Short Food Supply Chains
2019
The production and distribution of food are among the hot topics debated in the context of sustainable development. Short food supply chains (SFSCs) are now widely believed to be more sustainable in comparison to mass food delivery systems. To date, very little quantitative evidence exists on the impacts of various types of food supply chains. Using a cross-sectional quantitative approach, this study assesses the sustainability of distribution channels in short and long food supply chains based on 208 food producers across seven countries: France, Hungary, Italy, Norway, Poland, the United Kingdom, and Vietnam. Ten distribution channel types are used in this study. To provide a comprehensiv…
