A fast algorithm for muon track reconstruction and its application to the ANTARES neutrino telescope.
2011
An algorithm is presented, that provides a fast and robust reconstruction of neutrino induced upward-going muons and a discrimination of these events from downward-going atmospheric muon background in data collected by the ANTARES neutrino telescope. The algorithm consists of a hit merging and hit selection procedure followed by fitting steps for a track hypothesis and a point-like light source. It is particularly well-suited for real time applications such as online monitoring and fast triggering of optical follow-up observations for multi-messenger studies. The performance of the algorithm is evaluated with Monte Carlo simulations and various distributions are compared with that obtained …
Determination of a pre-heating sequence for the DONES Target Assembly
2021
Abstract Within the activities promoted by the EUROfusion consortium in support of the design and construction of the DEMO Oriented NEutron Source (DONES), a mock-up of its Target Assembly (TA), based on the configuration with a “bayonet” Back-Plate (BP) and available at ENEA Brasimone labs, is being adopted for the execution of experimental activities aiming at the validation of specific aspects of the target design. Despite the “integral”-TA concept is the current reference, experimental tests concerning the TA pre-heating phase are not significantly affected by the TA concept and are still representative even though conducted on the bayonet-TA concept. Indeed, the main objective of the p…
Generation Z and Organizational Listening on Social Media
2020
Young people are avid users of social media and have appeared as a powerful force for social change, as shown by the ranks of those who have joined Greta Thunberg in the global climate movement. In addition to challenging political institutions and governments, young people today are also holding the corporate world accountable. To respond to young people’s expectations, brands, and organizations have turned to social media to interact and build relationships with them. However, critics have lamented that these attempts often fail and that young people’s trust in institutions, brands, and organizations continues to decline. This article asks how young people perceive organizational listenin…
Employment sector and pay gaps: Genetic and environmental influences
2012
This paper examines the role of genetic factors and shared environment in explaining the choice of working in the public sector and public-private sector pay gaps. The analyses are done using data for Finnish twins that span the period from 1990 to 2004. The data are based on two sources. The first data are Finnish Twin Cohort conducted by Department of Public Health in University of Helsinki. These data have been matched with the Finnish Longitudinal Employer-Employee Data (FLEED) kept by Statistics Finland. The standard behavioural genetics decomposition and DF (DeFries and Fulker 1985) analyses indicate that public sector employment is broadly influenced by the genetic factors by around …
In-work benefits for married couples: an ex-ante evaluation of EITC and WTC policies in Italy
2014
This paper investigates labor supply and redistributive effects of in-work benefits for Italian married couples using a tax-benefit microsimulation model and a multi-sectoral discrete choice model of labor supply. We consider two in-work benefit schemes following the key principles of the Earned Income Tax Credit (EITC) and the Working Tax Credit (WTC) existing in the US and the UK, respectively. The standard design of these in-work benefits is however augmented with a new benefit premium for two-earner households in order to overcome the well-known disincentive effects that these welfare instruments may generate on secondary earners. In simulation, the proposed in-work benefits are finance…
Hedging foreign exchange rate risk: Multi-currency diversification
2016
Abstract This article proposes a multi-currency cross-hedging strategy that minimizes the exchange risk. The use of derivatives in small and medium-sized enterprises (SMEs) is not common but, despite its complexity, can be interesting for those with international activities. In particular, the reduction in the exchange risk borne through the use of natural multi-currency cross-hedging is measured, considering Conditional Value-at-Risk (CVaR) and Value-at-Risk (VaR) for measuring market risk instead of the variance. CVaR is minimized using linear programmes, while a multiobjective genetic algorithm is designed for minimizing VaR, considering two scenarios for each currency. The results obtai…
Return on capital in Spanish tourism businesses: A comparative analysis of family vs non-family businesses
2016
The analysis of the keys to competitiveness in the tourism sector has an unquestionable justification for its importance in the Spanish economy and its global growth prospects. The need for a better understanding of the keys to the competitiveness of the tourism firm is also fuelled by the magnitude of the challenges that it faces and by the sector structure, characterised by a notable weight of family-owned businesses. The objective of this research lies precisely in developing a diagnosis of the return on capital of the tourism sector and the determinants of its evolution in the family business (FB) vs non-family business (NFB). Specifically, this study focuses on the analysis of both fir…
Managing innovation of care services: An exploration of Norwegian municipalities
2016
AbstractThe social impact of care services provided by the public sector is significant. Nevertheless, these services have received relatively little attention from prior innovation management practices research. This paper addresses this gap by raising the question: What characterises management-driven innovation processes in public organisations providing care services? The qualitative exploration of this question is based on in-depth interviews with key managers in three Norwegian municipalities, and in-depth observation of one ongoing innovation initiative in one municipality. Our findings supplement the findings of prior research by showing that different actors are involved in differe…
More planet and less profit? The ethical dilemma of an oil producing nation
2019
Every oil producing nation is confronted with a complex and fundamental ethical dilemma. On the one hand, there are moral arguments for the nation to use the petroleum resource for the benefit of society and make it available for countries who do not have this natural resource endowment. On the other hand, there are moral arguments for not extracting and using fossil fuels because of CO2 emissions. In short, this creates tension between the need for government revenues to finance welfare benefits and the objective of preserving the environment. A complicating factor is that a nation's domestic oil and gas activities are in its nature global because the activities have a direct impact on the…
Determinants and consequences of auditor dyad formation at the top level of audit teams
2021
Abstract This study investigates the determinants and consequences of forming dyads at the top level of audit teams, i.e., dyads between concurring and lead auditor. We apply the sociological theory of homophily, i.e., the implicit preference for similar others, to hierarchically structured auditor dyads. Our regression analyses reveal that sharing the same gender and the same ethnicity, measured by dialect, increases the likelihood of dyad formation beyond what one would expect based on the characteristics of the pool of available auditors. Further, we observe that forming auditor dyads sharing the same age is avoided, suggesting that the need to establish a legitimate hierarchical relatio…
