Selección de personal basada en métodos difusos

2011

[ES] Las decisiones de los directivos en cuanto a la selección de personal determinan en gran medida el éxito de la empresa. Una elección adecuada de los empleados proporciona una ventaja comparativa. Proponemos un método borroso para la selección de personal basado en la gestión de competencias y la comparación con la valoración que la empresa considera más adecuada para cada trabajo (el candidato ideal). Nuestro método utiliza la distancia de Hamming y el Matching Level Index. Los algoritmos, implementados con el software Sta¿Designer, nos permite establecer un ranking de candidatos, incluso cuando las competencias del candidato ideal han sido evaluadas tan solo en parte. Nuestro enfoque …

Sinusoidal endothelial cells from guinea pig liver synthesize and secrete cellular fibronectin in vitro.

1987

Endothelial liver cells were obtained from guinea pig by enzymatic digestion and centrifugal elutriation. Cells were cultured on gelatin and fibronectin pretreated culture vessels. Endothelial cells were characterized by phase-contrast microscopy, electron microscopy and the presence of Factor VIII-related antigen. Fibronectin secretion was determined in cell-free supernatants by a sensitive and specific ELISA and localized on fixed cultured cells by immunofluorescence. [35S]Methionine endogeneously labeled fibronectin was immunoprecipitated from supernatants and cellular lysates and displayed on sodium dodecyl sulfate polyacrylamide slab gel electrophoresis. After attachment to the culture…

Leisure Adjustments of Older Finnish Adults during the Early Stages of the COVID-19 Pandemic

2022

The current approach to “aging well” emphasizes the importance of active leisure participation in late adulthood. This relates to the view that leisure activities enable older adults to stay physically, mentally, and socially active, and they thereby contribute to wellbeing. In spring 2020, leisure activity engagement was significantly hampered by the COVID-19 pandemic. This study explores leisure-related experiences and adaptation strategies among Finnish older adults during the period of strict physical distancing. The data comprises letters (N = 77) written by Finnish people (aged 70–93) that were analyzed using content analysis. The study suggests that the reorganization of leisure was …

Phylogeny of viroids, viroidlike satellite RNAs, and the viroidlike domain of hepatitis delta virus RNA.

1991

We report a phylogenetic study of viroids, some plant satellite RNAs, and the viroidlike domain of human hepatitis delta virus RNA. Our results support a monophyletic origin of these RNAs and are consistent with the hypothesis that they may be "living fossils" of a precellular RNA world. Moreover, the viroidlike domain of human hepatitis delta virus RNA appears closely related to the viroidlike satellite RNAs of plants, with which it shares some structural and functional properties. On the basis of our phylogenetic analysis, we propose a taxonomic classification of these RNAs.

Cambios en los usos del suelo y producción de escorrentía en ramblas mediterráneas: Carraixet y Poyo (1956-1998)

2007

Ana.Camarasa@uv.es Juan.Mateu@uv.es Este trabajo analiza el efecto de los cambios recientes en los usos del suelo en la génesis de escorrentía en ramblas mediterráneas utilizando un SIG. Para el cálculo de la producción de escorrentía se ha utilizado el método desarrollado por el S.C.S. modificado por Témez (1978) que combina los mapas de pendientes, usos del suelo y grupo hidrológico del suelo. Se ha aplicado una adaptación del método propuesta por Camarasa et al. (2006) basado en la interpretación hidrogeomorfológica de la cuenca para la estimación del grupo hidrológico de suelo. Los resultados muestran una variabilidad espacial y temporal importante en la dinámica de producción de escorr…

Characteristics and definition and characterization of new Valencian urban areas

2014

La expansión urbanística, junto con la generalización de los procesos de descentralización residencial y económica, ha conducido a un nuevo modelo de ciudad dispersa caracterizado por la dificultad de establecer sus límites precisos. Utilizando un índice de densidad de ejes viarios procedente de una fuente comercial, y por tanto fácilmente actualizable, se ha delimitado el fenómeno urbano en la Comunidad Valenciana. Se discute la utilidad de la metodología y su capacidad para captar el hecho urbano a partir del contraste con la cartografía de usos del suelo de Corine. Urban expansion, along with the generalization of the processes of residential and economic decentralization has led to a ne…

Impact of mobility restrictions on active aging; cross-sectional associations and longitudinal changes parallel to COVID-19 restrictions

2021

Background: Meaningful activities can be done in or around home, but opportunities for participation and active aging decrease when moving in smaller areas. Active aging refers to having an active approach to life in line with one's goals, ability and opportunities. In adults over 75 years with different baseline neighborhood mobility levels, we studied active aging scores two years prior to and amid COVID-19, when governments restricted mobility of residents to slow the COVID-19 outbreak. Methods: AGNES cohort data were collected in 2017-2018 and spring 2020. Individuals were queried about their will, ability, and opportunity, and extent of doing 17 activities, and subsequently, item, comp…

Maintenance of high quality of life as an indicator of resilience during COVID-19 social distancing among community-dwelling older adults in Finland

2021

Abstract Purpose Social distancing during the COVID-19 pandemic reduced possibilities for activities of choice potentially threatening quality of life (QoL). We defined QoL resilience as maintaining high quality of life and studied whether walking speed, absence of loneliness, living arrangement, and stress-coping ability predict QoL resilience among older people. Methods Community-dwelling 75-, 80-, and 85-year-old persons (n = 685) were interviewed and examined in 2017–2018 and were followed up during COVID-19 social distancing in 2020. We assessed QoL using the OPQOL-brief scale and set a cut-off for ‘constant high’ based on staying in the highest baseline quartile over the follow-up and…
