A Large Hadron Electron Collider at CERN

Abstract: This document provides a brief overview of the recently published report on the design of the Large Hadron Electron Collider (LHeC), which comprises its physics programme, accelerator physics, technology and main detector concepts. The LHeC exploits and develops challenging, though principally existing, accelerator and detector technologies. This summary is complemented by brief illustrations of some of the highlights of the physics programme, which relies on a vastly extended kinematic range, luminosity and unprecedented precision in deep inelastic scattering. Illustrations are provided regarding high precision QCD, new physics (Higgs, SUSY) and electron-ion physics. The LHeC is designed to run synchronously with the LHC in the twenties and to achieve an integrated luminosity of O(100)\,fb$^{-1}$. It will become the cleanest high resolution microscope of mankind and will substantially extend as well as complement the investigation of the physics of the TeV energy scale, which has been enabled by the LHC.

The eudaimonic and hedonic components of happiness: qualitative and quantitative findings

Abstract: This paper illustrates a new project developed by a cross-country team of researchers, with the aim of studying the hedonic and eudaimonic components of happiness through a mixed method approach combining both qualitative and quantitative analyses. Data were collected from 666 participants in Australia, Croatia, Germany, Italy, Portugal, Spain, and South Africa. A major aim of the study was to examine definitions and experiences of happiness using open-ended questions. Among the components of well-being traditionally associated with the eudaimonic approach, meaning in particular was explored in terms of constituents, relevance, and subjective experience. The Satisfaction With Life Scale (SWLS) was also administered to quantitatively assess the hedonic dimension of happiness. Results showed that happiness was primarily defined as a condition of psychological balance and harmony. Among the different life domains, family and social relations were prominently associated with happiness and meaningfulness. The quantitative analyses highlighted the relationship between happiness, meaningfulness, and satisfaction with life, as well as the different and complementary contributions of each component to well-being. At the theoretical and methodological levels, findings suggest the importance of jointly investigating happiness and its relationship with other dimensions of well-being, in order to detect differences and synergies among them.

Results of the ontology alignment evaluation initiative 2012

Abstract: Ontology matching consists of finding correspondences between semantically related entities of two ontologies. OAEI campaigns aim at comparing ontology matching systems on precisely defined test cases. These test cases can use ontologies of different nature (from simple thesauri to expressive OWL ontologies) and use different modalities, e.g., blind evaluation, open evaluation, consensus. OAEI 2012 offered 7 tracks with 9 test cases followed by 21 participants. Since 2010, the campaign has been using a new evaluation modality which provides more automation to the evaluation. This paper is an overall presentation of the OAEI 2012 campaign.

Estimating the impact of workplace bullying: humanistic and economic burden among workers with chronic medical conditions

Abstract: Background. Although the prevalence of work-limiting diseases is increasing, the interplay between occupational exposures and chronic medical conditions remains largely uncharacterized. Research has shown the detrimental effects of workplace bullying but very little is known about the humanistic and productivity cost in victims with chronic illnesses. We sought to assess work productivity losses and health disutility associated with bullying among subjects with chronic medical conditions. Methods. Participants () with chronic diseases answered a self-administered survey including sociodemographic and clinical data, workplace bullying experience, the SF-12 questionnaire, and the Work Productivity Activity Impairment questionnaire. Results. The prevalence of significant impairment was higher among victims of workplace bullying as compared to nonvictims (SF-12 PCS: 55.5% versus 67.9%, ; SF-12 MCS: 59.4% versus 74.3%, ). The adjusted marginal overall productivity cost of workplace bullying ranged from 13.9% to 17.4%, corresponding to Italian Purchase Power Parity (PPP) 2010 US$ 4182–5236 yearly. Association estimates were independent and not moderated by concurrent medical conditions. Conclusions. Our findings demonstrate that the burden on workers’ quality of life and productivity associated with workplace bullying is substantial. This study provides key data to inform policy-making and prioritize occupational health interventions.

The Minimal Entropy Martingale Measure and the Valuation Problem in Incomplete Markets

Abstract: Let χ be a family of stochastic processes on a given filtered probability space (Ω, F, (Ft)t∈T, P) with T⊆R+. Under the assumption that the set Me of equivalent martingale measures for χ is not empty, we give sufficient conditions for the existence of a unique equivalent martingale measure that minimizes the relative entropy, with respect to P, in the class of martingale measures. We then provide the characterization of the density of the minimal entropy martingale measure, which suggests the equivalence between the maximization of expected exponential utility and the minimization of the relative entropy.
