El papel de la autoestima y la soledad en el uso problemático del smartphone: diferencias de género
2021
RESUMEN El presente estudio investigó las relaciones entre la autoestima, la soledad y el uso problemático del smartphone y las diferencias de género. La muestra fue no probabilística y estuvo compuesta por 202 participantes (106 hombres y 96 mujeres), con edades comprendidas entre los 18 y los 58 años, que completaron las siguientes pruebas: Smartphone Addiction Scale, Social and Emotional Loneliness Scale for Adults y Escala de Autoestima de Rosenberg. Se calcularon los estadísticos descriptivos, la prueba U de Mann-Whitney, análisis de correlación bivariados y dos modelos de regresión múltiple jerárquica. Se hallaron diferencias significativas entre hombres y mujeres en el uso problemáti…
La vejez en soledad no deseada: procesos de significación y de dotación de sentido
2020
El objetivo de este trabajo ha sido abordar los procesos de significación y dotación de sentido de las personas mayores que sobreviven en soledad no deseada. Para ello, hemos realizado una etnografía en la ciudad de València. Durante la investigación, hemos observado que los sujetos participantes detentan un estatus social que está intensamente marcado por su separación de las dinámicas sociales que regían sus vidas y por una devaluación extrema de su vida en términos de reconocimiento. Su angustia, lejos de poder ser reductible a procesos psicológicos, es el fundamento de la realización de esfuerzos y acciones de carácter social, reestableciendo las relaciones que mantienen con su mundo bi…
El apoyo social y la soledad de las mujeres mayores usuarias de teleasistencia
2016
Abstract.SOCIAL SUPPORT AND LONELINESS OF ELDERLY WOMEN TELECARE USERSLoneliness is a negative subjective experience based on the evaluation of the quality and the amount of the individual’s social interactions. Older adults’ social networks decrease because of losses associated to widowhood, retirement and an adaptive selection process; they eliminate those relations who are less intimate and the emotionally significant contacts are the only ones who remain. Because of these and other factors, elderly women who live alone were identified as being in major risk of feeling lonely. Objectives. 1. Learning about the prevalence of loneliness in a sample of older women who are users of a telecar…
La soledad de las mujeres mayores que viven solas
2017
España está entre los países más envejecidos del mundo y así como ocurre en otros países, los datos muestran una feminización del proceso de envejecimiento poblacional. Investigaciones recientes indican la preferencia de los españoles mayores por vivir en sus propias viviendas frente a mudarse a la casa de sus familiares o ser institucionalizados. A raíz de estos cambios sociodemográficos, se viene notando una creciente tendencia de los hogares unipersonales encabezados por personas mayores. Al ser más longevas, las mujeres tienen más probabilidad de vivir solas durante más años que los varones mayores. Desde el modelo de discrepancia cognitiva, la soledad es una sensación desagradable resu…
Advancing Design Science Research with Solution-based Probing
2019
We propose solution-based probing as an extension of action design research. The core idea is that researchers bring a prototype solution (probe) into one or more fields and explore to synthesize robust and generalizable design knowledge, along with knowledge of the phenomena and correlations we discover. We believe proposing solutions creates opportunities for researchers to innovate and to document the impact. In addition, solutions can be effective probes for advancing theory, in terms of design theories and in creating exploratory foundations for behavioral and causal theory. We illustrate solution-based probing with four exemplar studies in the areas governance of municipalities, polic…
Global urban environmental change drives adaptation in white clover
2022
Made available in DSpace on 2022-04-28T19:52:06Z (GMT). No. of bitstreams: 0 Previous issue date: 2022-03-18 Urbanization transforms environments in ways that alter biological evolution. We examined whether urban environmental change drives parallel evolution by sampling 110,019 white clover plants from 6169 populations in 160 cities globally. Plants were assayed for a Mendelian antiherbivore defense that also affects tolerance to abiotic stressors. Urban-rural gradients were associated with the evolution of clines in defense in 47% of cities throughout the world. Variation in the strength of clines was explained by environmental changes in drought stress and vegetation cover that varied am…
Climate change and reindeer management in Finland : Co-analysis of practitioner knowledge and meteorological data for better adaptation
2020
We studied interannual variability and changes over time in selected climate indices in the reindeer management area (RMA) in northern Finland. We present together the knowledge possessed by reindeer herders with information from meteorological measurements over three decades. The practitioner knowledge was gathered via a survey questionnaire addressing herder observations of long-term changes (approximately during the past 30 years) in climatic conditions and their impacts on herding during the four seasons. A set of temperature-, precipitation- and snow-related indices relevant for herding within the RMA was derived from spatially interpolated daily meteorological data (1981–2010). Climat…
Climbing for equality: overcoming social inequality through sport : a narrative inquiry into the sport lives of five visually disabled climbers in Me…
2016
This master thesis is a qualitative narrative inquiry that illustrates and explores the stories of five visually disabled participants who took up the practice of rock climbing and mountaineering as a means to overcome social inequality. The researcher’s role within the study was that of active participation by being the coach and mountain guide for the participants over a period of five years. This narrative analysis reconstructs the stories of the participants in a coherent thematic analysis from a Marxist historical perspective, explaining how inequality towards the participants was created, by using the concept of Cultural Hegemony from Antonio Gramsci. The mentioned methodology was cho…
Hierarchies of knowledge, incommensurabilities and silences in South African ECD policy: Whose knowledge counts?
2017
AbstractPolicy for young children in South Africa is now receiving high-level government support through the ANC’s renewed commitment to redress poverty and inequity and creating ‘a better life for all’ as promised before the 1994 election. In this article, I explore the power relations, knowledge hierarchies and discourses of childhood, family and society in National Curriculum Framework (NCF) as it relates to children’s everyday contexts. I throw light on how the curriculum’s discourses relate to the diverse South African settings, child rearing practices and world-views, and how they interact with normative discourses of South African policy and global early childhood frameworks. The NCF…
