Panorámica de la desigualdad digital en España: operacionalización y dimensionamiento de las brechas digitales de accesibilidad, habilidades y formas…
2019
En este artículo, se realiza un análisis estadístico de la desigualdad digital en España a partir de una operacionalización de las tres brechas digitales más relevantes: (1) accesibilidad a los dispositivos TIC; (2) competencias y habilidades digitales; y (3) prácticas digitales y formas diferenciales de uso. La metodología es cuantitativa, basada en la última oleada (2018) de la encuesta sobre equipamientos tecnológicos en el hogar del INE (TIC-H), a partir de la cual se ha desarrollado un análisis comparativo por género, edad, nivel de estudios, situación laboral y tipo de hábitat residencial. Los resultados muestran cómo la desigualdad de acceso tiene actualmente más que ver con las moda…
Diurnal Cycle Relationships between Passive Fluorescence, PRI and NPQ of Vegetation in a Controlled Stress Experiment
2017
In order to estimate vegetation photosynthesis from remote sensing observations; some critical parameters need to be quantified. From all absorbed light; the plant needs to release any excess that is not used for photosynthesis; by non-photochemical quenching; by fluorescence emission and unregulated thermal dissipation. Non-photochemical quenching (NPQ) processes are controlled photoprotective mechanisms which; once activated; strongly control the dynamics of photochemical efficiency. With illumination conditions increasing and decreasing during a diurnal cycle; photoprotection mechanisms needs to change accordingly. The goal of this work is to quantify dynamic NPQ; measured from active fl…
Apmierinātība ar partnerattiecībām un uztvertais stress saplūdušās un nukleārās ģimenēs.
2021
Bakalaura darba mērķis ir noskaidrot, kādas atšķirības apmierinātībā ar partnerattiecībām un uztverto stresu pastāv starp indivīdiem nukleārās un saplūdušās ģimenēs. Pētījuma izlasi veido 610 indivīdi, no kuriem 430 ir partnerattiecībās nukleārā ģimenē un 180 — saplūdušā ģimenē. Darbā tiek izmantotas divas aptaujas: Apmierinātība ar partnerattiecībām un Uztvertā stresa skala. Pētījuma rezultāti liecina, ka nav statistiski nozīmīgas atšķirības starp salīdzināmajām grupām attiecībā uz apmierinātību ar partnerattiecībām un uztverto stresu. Rezultāti atklāj statistiski nozīmīgas sakarības starp apmierinātību ar partnerattiecībām un uztverto stresu, proti, palielinoties uztvertajam stresam, sama…

Exploring Early Adolescents' Problem-Focused Strategies for Coping With Stressful IT Use Experiences
2022
In today’s technology-oriented world, individuals’ ability to cope with information technology (IT) has become increasingly important. This is especially relevant for early adolescents, who are expected to use IT from an early age on as part of their everyday lives. Although early adolescents’ IT use and its outcomes have been studied, their related coping strategies have received less attention. The current study focuses on early adolescents’ problem-focused strategies used to cope with stressful IT use experiences. The underlying data consist of semistructured interviews with 31 early adolescents. The results show that the strategies used by early adolescents differ in terms of their perv…
Effect of Non-Surgical Periodontal Treatment on Oxidative Stress Markers in Leukocytes and Their Interaction with the Endothelium in Obese Subjects w…
2020
Aim: The primary objective of this pilot study was to evaluate the effect of non-surgical periodontal treatment. The secondary aim was to evaluate the effect of dietary therapy on both parameters of oxidative stress in leukocytes and leukocyte-endothelial cell interactions in an obese population. Methods: This was a pilot study with a before-and-after design. Forty-nine obese subjects with periodontitis were randomized by means of the minimization method and assigned to one of two groups, one of which underwent dietary therapy while the other did not. All the subjects underwent non-surgical periodontal treatment. We determined periodontal, inflammatory and oxidative stress parameters&mdash
Effects of Job Content and Physical Activity on Body Mass Index among Obese Managers of the Mexican Manufacturing Industry
2020
Mental health disorders resulting from work stressors are increasing in the Mexican manufacturing industry and worldwide. Managerial positions in these contexts are highly stressful, and although physical activity may reduce the negative effects of work stress, the relationships between these two aspects regarding their effects on the body mass index (BMI) of obese managers are scarcely studied. This article aims to study such relationships by using the Job Content Questionnaire (JCQ) dimensions with the Baecke’s physical activity questionnaire dimensions and analyzing their effects on the BMI. A sample of 255 managers from the Mexican industry, with a (BMI > 30) participated by answerin…
The corticotrophin-releasing factor/urocortin system regulates white fat browning in mice through paracrine mechanisms.
2015
Objectives:\ud The corticotrophin-releasing factor (CRF)/urocortin system is expressed in the adipose tissue of mammals, but its functional role in this tissue remains unknown.\ud \ud Methods:\ud Pharmacological manipulation of the activity of CRF receptors, CRF1 and CRF2, was performed in 3T3L1 white pre-adipocytes and T37i brown pre-adipocytes during in vitro differentiation. The expression of genes of the CRF/urocortin system and of markers of white and brown adipocytes was evaluated along with mitochondrial biogenesis and cellular oxygen consumption. Metabolic evaluation of corticosterone-deficient or supplemented Crhr1-null (Crhr1−/−) mice and their wild-type controls was performed alo…
Study of the mechanisms of oxidative stress, mitochondrial function and endoplasmic reticulum stress in obesity. Role in subclinical atherosclerosis …
2019
El aumento alarmante de la prevalencia de obesidad a nivel mundial y la enorme carga de enfermedad asociada ha generado una creciente demanda de estrategias para frenar la epidemia y / o mitigar los efectos dañinos de la obesidad sobre la salud. Para ello se requiere un compromiso firme y sinérgico por parte de todas las fuerzas sociales, no sólo para desarrollar estrategias preventivas, sino también para contribuir al conocimiento de los eventos patológicos y los mecanismos involucrados en el desarrollo de esta enfermedad. Por ello, el objetivo principal de la presente tesis doctoral es profundizar en los mecanismos subyacentes de la obesidad, especialmente en aquellos relacionados con el …
