Unveiling the strong interaction among hadrons at the LHC
2020
One of the key challenges for nuclear physics today is to understand from first principles the effective interaction between hadrons with different quark content. First successes have been achieved using techniques that solve the dynamics of quarks and gluons on discrete space-time lattices1,2. Experimentally, the dynamics of the strong interaction have been studied by scattering hadrons off each other. Such scattering experiments are difficult or impossible for unstable hadrons3–6 and so high-quality measurements exist only for hadrons containing up and down quarks7. Here we demonstrate that measuring correlations in the momentum space between hadron pairs8–12 produced in ultrarelativistic…
Challenges of nation-branding for stimulation of Latvian exports
2017
Abstract The presented research aims to contribute to the conceptualisation of the nation-brand of Latvia with the purpose of stimulation of national export performance. The subject of the research is three aspects presumably challenging the branding of Latvia with reference to national export development. The investigated challenges are the barriers and opportunities for green-branding of Latvia; the absence of the generally accepted indication of the geographical identity of the Baltic region; and the contradictable popular image of Latvia as a cheap country. The research poses two research questions inquiring into the issues of nation-branding of Latvia currently being faced in the conte…
The Developmental Contribution From Mobile Phones Across the Agricultural Value Chain in Rural Africa
2011
Published version of an article from the journal: The Electronic Journal of Information Systems in Developing Countries. Also available fro the publisher: http://www.ejisdc.org/Ojs2/index.php/ejisdc/article/viewFile/849/377 The most widespread information and communication technology (ICT) in developing countries today is the mobile phone. The majority of people in the least developed countries still live in rural areas and their livelihood depends on the primary industries. This study investigates the use of mobile phones among farmers in rural Tanzania in order to supply empirical data on the developmental role of this technology. The results show that the improved access to communication…
The background music-content congruence of TV advertisements: A neurophysiological study
2021
Abstract Music affects viewers’ responses to advertisements. In this study we present the findings of an experiment that investigates the emotional and cognitive reactions of subjects’ brains during exposure to television advertisements with music congruent, and incongruent, with the advertisement content. We analyze the electroencephalography signals and eye-tracking behaviors of a group of 90 women watching six TV advertisements. The study's findings suggested that incongruent music generates higher levels of attention and advertisement recall. On the other hand, frontal asymmetry measured through electroencephalography was shown to be higher with congruent music. Similarly, cognitive wor…
Searching for new paradigms in a globalized world: Business ethics as a management strategy
2008
The process of globalization is an undeniable reality of today's world. Yet, paradoxically, the cornerstone of this phenomenon, economic performance, varies widely across the world whatever indicator (for example, GDP/habitant, competitiveness) we choose to use to compare countries. Increasingly, studies tend to explain this apparently paradoxical situation with reference to the issue of corruption and ethics. In essence, corruption is perceived to be an important impediment to the economic development of a country (or area). Many studies of corruption are focused at the national level. The aim of this conceptual paper is to explore the role of the firm (as opposed to national states or int…
Development of net energy ratio and emission factor for quad-generation pathways
2014
Published version of an article in the journal: Energy Systems. Also available from the publisher at: http://dx.doi.org/10.1007/s12667-014-0126-4 The conversion of biomass to four different outputs via gasification is a renewable technology that could reduce the use of fossil fuels and greenhouse gas (GHG) emissions. This study investigates the energy aspects for a new concept of biomass based quad-generation plant producing power, heat, methanol and methane. Circulating fluidized bed gasifier and the gas technology institute (GTI) gasifier technologies are used for this quad-generation process. Two different biomass feedstocks are considered in this study. The net energy ratio for six diff…
An upper echelons perspective on information technology business value
2017
This paper argues that information technology (IT) outcomes are more valuable to companies when their top management team (TMT) moves from flirting with IT to marriage. Previous research has demonstrated an association between top management support (TMS) and IT value. We extend the concept of TMS with the imbrication metaphor to define the construct of TMT-IT imbrication, which allows us to account for a tighter and continuous entwining of the TMT and IT to create IT value. Our definition of the TMT-IT imbrication construct embraces four dimensions: involvement, participation, attention, and use. In addition, with the support of upper echelons (UE) theory, we explore certain managerial tra…
Los grupos de interés en las entidades de crédito Españolas
2012
RESUMENSe plantean los orígenes, evolución y clasificación de los grupos de interés (stakeholders). Se pone de relieve la relación que se entabla entre la entidad de crédito como organización social y sus diferentes grupos de interés, analizándose la importancia que se asigna a estos.El trabajo de campo se realizó a través de una encuesta contestada por 57 entidades de crédito españolas. Los resultados del estudio muestran la sensibilidad de las entidades de crédito hacia la RSE (Responsabilidad Social de la Empresa), con referencia al conjunto del sector financiero español. Nuestro objetivo es analizar la importancia que tienen los diversos grupos de interés: accionistas, empleados, client…

ResumenLas empresas de nueva creación juegan un papel crucial en la generación de empleo, el crecimiento económico, la innovación y la competitividad. Ello ha llevado a un número creciente de instituciones públicas a dedicar ingentes recursos al apoyo y fomento de iniciativas empresariales. Resulta por ello de especial interés analizar la eficacia de los distintos programas e identificar cuáles son las prácticas más efectivas. Este trabajo tiene como objetivo avanzar en la mejora de los sistemas de evaluación de programas de ayuda a emprendedores y mostrar cómo las mejoras introducidas pueden tener efectos sobre la calidad de los negocios creados. Para ello se analiza en profundidad el caso…
Empreendedorismo, inovação e internacionalização: o papel moderador das instituições
2021
Abstract The favorable effects of innovation and internationalization on the development of the economies of countries have been prominent factors in multiple management studies. The objective of this document is to make a theoretical review of the studies contained in the ScienceDirect (Elsevier) and ResearchGate databases, to offer an integrating framework of those institutional factors in the countries that favor the positive spillover of these two strategic actions carried out by companies: innovation and internationalization. As a result, we observed that an institutional framework characterized by a simplification of bureaucratic administrative procedures to access the financial resou…
