Kaikki ei ole suoraviivaista : yleistetyn additiivisen mallin (GAM) käyttö ja edut työn piirteiden käyräviivaisten työhyvinvointivaikutuksien tutkimi…
2010
Tilastomenetelmien käyttö yhteiskuntatieteellisessä tutkimuksessa on yksipuoleista. Tässä tutkimuksessa esiteltiin uusi analyysimenetelmä yleistetty additiivinen malli (GAM), jota verrattiin usein käytettyyn yleistettyyn lineaariseen malliin (GLM). Analyysimenetelmiä sovellettiin työhyvinvoinnin tutkimukseen. Työhyvinvoinnin syntyä tarkasteltiin työpsykologien kehittämien Karasekin interaktiomallin, työn vaatimusten ja voimavarojen (TV-TV) mallin sekä Warrin vitamiinimallin näkökulmasta. Kaikki kolme työhyvinvoinnin mallia selittävät työhyvinvointia työn piirteillä. Työhyvinvointia mitattiin työstressin ja työn imun kautta. Tutkimustehtävinä oli selvittää eroavatko GAM:n ja GLM:n tulokset j…
Hydro-mechanical analysis of volcanic ash slopes during rainfall
2016
Rainfall-induced landslides in volcanic ashes represent a major natural hazard in many regions around the world. Owing to their loose structure, volcanic ash slopes are prone to rainfall-induced landslides. The paper presents a continuum modelling approach for the analysis of wetting-induced instability phenomena at the onset of failure in loose volcanic ash slopes. A numerical simulation of a landslide-prone volcanic slope in Costa Rica is carried out with a two-dimensional hydro-mechanical finite-element slope model. A constitutive model based on the effective stress concept extended to partially saturated conditions is used to reproduce the volcanic ash hydro-mechanical behaviour. The m…
Laparoscopic retropubic colposuspension for the treatment of genuine stress incontinence. long term follow up
2003
Objectives: The minimal surgical treatment of stress urinary incontinence with endoscopic operation has four basic advantages compared with traditional open procedures: decreased blood loss due to better visualization of the space of Retzius, decreased postoperative pain, shorter hospitalization and faster recovery. Comparative studies have shown a higher subjective and objective cure rate for the retropubic urethropexy(Burch procedure) than for the anterior colporraphy or endoscopic needle urethropexy(1). The aim of this study is to evaluate the safety, the efficacy and morbility of laparoscopic Burch procedure for the surgical treatment of genuine stress incontinence. Methods: We reviewed…
Global and local stressors on community succession in the Mediterranean intertidal zone
Psychosocial Work Factors, Job Stress and Strain at the Wheel: Validation of the Copenhagen Psychosocial Questionnaire (COPSOQ) in Professional Drive…
2019
Introduction: Psychosocial work environment has been related to many negative health outcomes in different workforces. However, evidence in this regard is still limited in the case of transport workers, and most of the tools used in research, often excessively generic, do not fully consider the specific key stressors and adverse issues present in the psychosocial environment of professional driving. Objective: Thus, the purpose of this study was to obtain a complete description of the validation of measurement applied to psychosocial factors at work in professional drivers, using the Enterprise version (2018) of COPSOQ-III. Methods: The data was collected from 726 Spanish professional drive…
I’m Not Good for Anything and That’s Why I’m Stressed: Analysis of the Effect of Self-Efficacy and Emotional Intelligence on Student Stress Using SEM…
2020
Stress negatively affects the well-being and the quality of life of the society. Specifically in the academic context, it is relevant to analyze its levels due to its impact on performance and learning. There are factors that affect the said stress including, among others, self-efficacy, and emotional intelligence. The purpose of this study is to analyze how emotional intelligence and perceived self-efficacy affect student stress. In order to show this influence, two complementary methodologies are implemented: the structural equation models (SEMs) and the comparative qualitative analysis (QCA). A total of 477 students (85% of women) from a private University of Valencia participated in the…
Stress, Professional Lifestyle, and Telomere Biology in Elite Athletes: A Growing Trend in Psychophysiology of Sport
2020
Professional lifestyle and championship period often put a great deal of pressure on athletes, who usually experience highly stressful periods during training for competitions. Recently, biomarkers of cellular aging, telomere length (TL) and telomerase activity (TA), have been considered to investigate the effects of stress and lifestyle factors. Studies in non-athletic populations have shown that stress and poor lifestyle decrease TL and TA. On the other hand, it has been shown that in general, exercise increases TL and its activity, although the underlying mechanisms remained largely unexplored. TL and TA outcomes in elite athletes remain inconclusive and mainly affected by confounding fa…
Oxidative Stress and DNA Damage in Human Gastric Carcinoma: 8-Oxo-7'8-dihydro-2'-deoxyguanosine (8-oxo-dG) as a Possible Tumor Marker
2013
We characterized the oxidative stress (OS) status by the levels of reduced/oxidized glutathione (GSH/GSSG), malondialdehyde (MDA) and the mutagenic base 8-oxo-7'8-dihydro-2'-deoxyguanosine (8-oxo-dG) in human gastric carcinoma (HGC) samples and compared the results with normal tissue from the same patients. We also analyzed 8-oxo-dG in peripheral mononuclear cells (PMNC) and urine from healthy control subjects and in affected patients in the basal state and one, three, six, nine and twelve months after tumor resection. The levels of DNA repair enzyme mRNA expression (hOGG1, RAD51, MUYTH and MTH1) were determined in tumor specimens and compared with normal mucosa. Tumor specimens e…
