Stress appraisal at work: its measurement and implications for well-being
2013
En los cinco artículos que forman parte de la presente tesis, se han comentado los conceptos subyacentes así como los resultados obtenidos. En este apartado, se resaltan los objetivos de la presente tesis, la metodología utilizada, así como las conclusiones generales que se pueden extraer en base a los estudios realizados. Objetivos En esta tesis analizamos el fenómeno del estrés laboral desde la perspectiva cognitiva (Lazarus y Folkman, 1984) y desde el enfoque que nos ofrece la psicología positiva (Seligman y Csikszentmihayi, 2000). El objetivo de la presente tesis ha sido desarrollar y validar una nueva medida de la percepción de eustrés y distrés tanto desde la Teoría Clásica del Test (…
Metallothionein genes in the sea urchin Paracentrotus lividus
2014
Metallothioneins (MTs) constitute a heterogeneous superfamily of cysteine rich proteins, which coordinate divalent (Zn2+, Cd2+) or monovalent (Cu+) metal ions. Several functions have been proposed for these peptides, ranging from toxic metal protection to physiological metal homeostasis, free radical scavenging, oxidative stress protection, antiapoptotic defense, control of the redox status of the cell and also a role during development. Regarding the MT system in vertebrates’ nearest kin, little information is available at present. Recently MTs were also characterized in cephalochordates. Hence in order to shed some light on MT origin and functional differentiation through evolution, we st…
The emergence of technostress in software development work: Technostressors and underlying factors
2022
Software development is a fast-growing market that is heavily tied to information technology (IT) use. Despite the high utilization of IT and high stress levels of software developers, research has largely neglected the effect of IT use on stress experienced by software developers. To address this gap in the research, we employ the concept of technostress. Prior technostress research has found many technostress-creating factors that cause severe negative consequences for both organizations and their employees. Despite these advancements, little is known about how technostress emerges in different organizational contexts and the underlying factors behind the technostress creators in these co…
Past, present, and future of green product innovation
2021
Firms are under constant pressure from various governmental and nongovernmental agencies to switch from conventional environmentally polluting products to green product innovations (GPIs). However, the relevant research pertaining to GPI has been published in a diverse set of journals that vary in their scope and readership and, therefore, the scholarly contribution to the topic remains largely fragmented. This study has utilised a systematic literature review approach to examine the literary corpus on GPI to paint a holistic picture of its different aspects. The content and thematic analysis of 85 studies resulted in the extraction of seven key research themes: organisational capabilities,…
Compared Binding Properties between Resveratrol and Other Polyphenols to Plasmatic Albumin: Consequences for the Health Protecting Effect of Dietary …
2014
International audience; Phytophenols are considered to have beneficial effects towards human physiology. They are food microcomponents with potent chemopreventive properties towards the most three frequent contemporary human diseases, e.g., cardiovascular alterations, cancer and neurodegenerative pathologies. Related to this, the plasmatic form and plasmatic level of plant polyphenols in the body circulation are crucial for their efficiency. Thus, determinations of the binding process of resveratrol and of common flavonoids produced by major edible plants, berries and fruits to plasma proteins are essential. The interactions between resveratrol and albumin, a major plasma protein, were comp…
Regional headquarters and foreign direct investment
2022
Headquarters (HQs) provide a wide range of services, playing a fundamental role in Foreign Direct Investment (FDI). We use the structural gravity equation to investigate the effect of regional HQs on three dimensions of FDI (number of foreign projects, capital investment, and jobs) at the country-pair-sector level. Furthermore, we explore two underlying mechanisms that help explain this relationship: financial constraints and informational costs and uncertainty. We find a positive effect of regional HQs on FDI, as well as intercountry and intersector spillovers. Our results are robust, accounting for HQ intensity, domestic investment, and endogeneity tests.
Skolēna līderprasmju attīstības metodes vispārizglītojošās skolas kontekstā
2015
Mūsdienu Latvijas vispārizglītojošā skolā skolēni apgūst daudz mācību priekšmetu: matemātiku, dabaszinības, valodas, literatūru, u.c. Bet nevienā no šiem priekšmetiem netiek mērķtiecīgi attīstītas komunikācijas prasmes, emociju savaldīšana, empātija un līdera prasmes, kuras ir tik nepieciešamas mūsdienu pasaulē. Šī darba mērķis ir teorētiski izpētīt un praktiski pārbaudīt līdera prasmes attīstības metodes, kuras ir pielietojami skolas vidē. No literatūras analīzes tika secināts, ka līderība ir emocionālās inteliģences augstāka pakāpe, un lai attīstītu līdera prasmes, jāstrādā pie emocionālas inteliģences attīstīšanās. Šim nolūkam darba gaitā bija izstrādāts nodarbības kurss, kurā piedalījās…
Association between Anxiety, Quality of Life and Academic Performance of the Final-Year-Students in Latvia
2021
The main objective of this study was to investigate the association between final-year students’ anxiety level and quality of life (QOL) with their academic achievements. A longitudinal study was performed in regular schools and in high-rated gymnasiums at the beginning and at the end of the school year. Multiple linear regression models were built for the association between level of anxiety/QOL with academic achievements. Type of school and gender—but not the level of anxiety—were the main predictors of academic achievements of 287 adolescents (e.g., for mathematics, the effect estimates were: β = −1.71 [95% confidence interval −2.21
Dynamique fluvial, changement global et pression anthropique dans le bassin, le cours et le delta de l'Ébre
2017
Le fonctionnement des rivières du bassin de l’Èbre a subi d’importants changements depuis 1950. Il s’agit d’un processus rapide et très marqué, de simplification et de stabilisation sur le fleuve principal et sur ses principaux affluents pyrénéens. Ce processus s’est manifesté par des changements dans la morphologie fluviale, le développement de la végétation sur les lits, un rétrécissement de l’espace naturel fluvial et une incision des lits fluviaux. Les facteurs de ce processus sont le changement global dans le bassin, la construction de réservoirs d’eau et d’autres nombreuses pressions humaines directes, notamment d’extractions de graviers et de canalisations. Le delta de l’Èbre, actuel…
Enabling and constraining family: young women building their educational paths in Tanzania
2015
For an increasing number of African girls and women, upgrading the level of education has become a strategy for life improvement. This paper analyses the role that family plays in enabling women's education and contributes to understanding on the interconnectivity of education, work and family in women's lives in collective societies. The analysis focuses on how young Tanzanian women perceive the role of family and education in their ‘youth task’, of becoming adult. The analysis is based on interviews with seven young Tanzanian women enrolled in non-formal secondary education and nine professional women enrolled in higher education. The results show that the women were determined to pursue …
