First Order Electroweak Phase Transition from (Non)Conformal Extensions of the Standard Model
2015
We analyse and compare the finite-temperature electroweak phase transition properties of classically (non)conformal extensions of the Standard Model. In the classically conformal scenarios the breaking of the electroweak symmetry is generated radiatively. The models feature new scalars coupled conformally to the Higgs sector as well as new fermions. We uncover the parameter space leading to a first order phase transition with(out) the Veltman conditions. We also discuss dark (matter) aspects of some of the models and compare with existing literature when appropriate. We observe that to accommodate both, a first order electroweak phase transition, and a phenomenologically viable dark matter …
On axionic dark matter in Type IIA string theory
2013
We investigate viable scenarios with various axions in the context of supersymmetric field theory and in globally consistent D-brane models. The Peccei-Quinn symmetry is associated with an anomalous U(1) symmetry, which acquires mass at the string scale but remains as a perturbative global symmetry at low energies. The origin of the scalar Higgs-axion potential from F-, D- and soft breaking terms is derived, and two Standard Model examples of global intersecting D6-brane models in Type II orientifolds are presented, which differ in the realisation of the Higgs sector and in the hidden sector, the latter of which is of particluar importance for the soft supersymmetry breaking terms.
Higgs production in a warped extra dimension
2012
Measurements of the Higgs-boson production cross section at the LHC are an important tool for studying electroweak symmetry breaking at the quantum level, since the main production mechanism gg → h is loop-suppressed in the Standard Model (SM). Higgs production in extra-dimensional extensions of the SM is sensitive to the Kaluza-Klein (KK) excitations of the quarks, which can be exchanged as virtual particles in the loop. In the context of the minimal Randall-Sundrum (RS) model with bulk fields and a brane-localized Higgs sector, we derive closed analytical expressions for the gluon-gluon fusion process, finding that the effect of the infinite tower of virtual KK states can be described in …
The role of transportation and its involved sources of energy in the environmental assessment of marble producing sites
2018
Marble is acquiring large popularity as building material. Since building materials are now required to be characterized by high energy and environmental performances, marble is entailed to fulfill top-level requirements. About its environmental performances an important European Decision establishes criteria for the award of the Community eco-label to this material. Unfortunately, this Decision is focused on mining and processing activities, seemingly neglecting marble transport. In contrast, this phase affects the whole working chain because it releases (pollutant) emissions and involves the use of primary and, in case, secondary energy sources. Here, the focus is on the role played by tr…
Trade Union Practices in the EU and Latvia: Experience for Eastern Partnership Countries
2014
Abstract The article will show major dimensions in the experience of EU Member States that could be shared with the Eastern Partnership (EaP) countries. The framework of the study is the EU concept of trade unions in social dialogue and social partnership in the public sector. This study outlines the concept of social dialogue as a core element of industrial relations and will focus on industrial relations specifically in the public sector. The authors have elaborated the approach to industrial relations and social dialogue taking into account comparative approach to definitions provided by international institutions such as ILO and OECD, as well as institutions in the EU and Latvia. Latvia…
Una máquina para la industria medieval. Los batanes del sur valenciano : integración y negocio. Nuevas aportaciones (1490-1502).
2021
El artículo tiene como objetivo el estudio de la región batanera de las comarcas del sur valenciano a través de nuevas aportaciones documentales. A lo largo del siglo XV y principios del siglo XVI, en las comarcas de la Vall d'Albaida, el Comtat y Alcoià el número de batanes hidráulicos aumentó hasta los 38 molinos en funcionamiento. El artículo muestra las causas de esta concentración, explica las características técnicas que aportan los documentos, y la adaptación de los batanes al conjunto de la red molinar de la zona. El trabajo concluye explicando los sectores sociales y económicos (artesanos empresarios) que organizaron y protagonizaron este desarrollo técnico e industrial, aportando …
Corporate Social Responsibility: A Survey of the Italian SA8000 Certified Companies
2005
Today’s society requires companies to act more and more effectively for the general good, by respecting human rights and the environment. Innovative and enlightened companies try to meet this need through the adoption of several initiatives. Accordingly, the International Standard Organisation is now working on attempts to unify these initiatives and to formulate an internationally recognised standard, providing guidance to companies on social responsibility. Currently the SA8000 international standard is the most often used tool – based on Corporate Social Responsibility (CSR) philosophy – which guarantees the respect of fundamental workers’ rights. Since 2003, Italy holds the world record…
Unveiling Barriers and Enablers of Risk Management in Interoperability Efforts
2014
eGovernment efforts are, as general IS efforts, associated with considerable risk. As eGovernment matures and interoperability becomes more ingrained in eGovernment efforts, it will be interesting to explore how the increased complexity affects risk. Still, research on risk management in the context of eGovernment is sparse and our understanding of the phenomenon equally so. This qualitative study investigates risk management in the Norwegian public sector. Based on 11 interviews with experts from nine public organizations, we identified six barriers and eight enablers to risk management in eGovernment settings. Our findings suggest that interoperability has important implications for how r…
Exploring Why Global Health Needs Are Unmet by Public Research Efforts: The Potential Influences of Geography, Industry, and Publication Incentives
2019
Background It has been well established that research is not addressing health needs in a balanced way: much more research is conducted on diseases with more burden in high-income countries than on those with more burden in lower-income countries. In this study, we explore whether these imbalances persist and inquire about the possible influence of three factors: geography, industry, and publication incentives. Methods We use WHO data on the Global Burden of Disease as a proxy measure of health needs and bibliometric information as a proxy for research efforts. Scientific publications on diseases were collected from MEDLINE using MeSH terms to identify relevant publications. We used Web of …
Different ways of measuring performance in the service industries: application in Spanish small and medium-sized hotels
2008
There is no suitable unit of analysis for explaining the profitability and competitiveness of the company, as typically pointed out in the debate between the disciplines of economics and management. After a study of the possible variables, we opted for those of minimum cost output and productivity, using these two measurements to analyse their application to Spanish hotels. The subsequent objective was to attempt to identify general strategies that could be applied to any SME within service industries. In situations where time and resources are not readily available to create action plans for each of the different types of SME, there is a need for incentives that can be applied to the creat…
