Psychometric properties and factor structure of the Satisfaction with Life Scale in an elderly Portuguese retirees students sample
2017
El objetivo principal de este estudio ha sido analizar las propie- dades psicométricas de la escala de Satisfacción con la Vida (SWLS) en una muestra de 363 estudiantes jubilados pertenecientes a varias universidades portuguesas. El 70% de los participantes eran mujeres frente a un 30% de hombres, con una media de edad de 67 años (SD = 7.59) y un rango de edad comprendido entre 48 y 90 años. Se realizó un Análisis Factorial Ex- ploratorio con R Commander y un Análisis Factorial Confirmatorio con Amos 18.0. El modelo que obtuvo un mejor ajuste estaba compuesto por un único factor. El índice de consistencia interna de la escala en su conjun- to fue de .777. En cuanto a la validez concurrente,…
Multimodal Aposematic Defenses Through the Predation Sequence
2021
Aposematic organisms warn predators of their unprofitability using a combination of defenses, including visual warning signals, startling sounds, noxious odors, or aversive tastes. Using multiple lines of defense can help prey avoid predators by stimulating multiple senses and/or by acting at different stages of predation. We tested the efficacy of three lines of defense (color, smell, taste) during the predation sequence of aposematic wood tiger moths (Arctia plantaginis) using blue tit (Cyanistes caeruleus) predators. Moths with two hindwing phenotypes (genotypes: WW/Wy = white, yy = yellow) were manipulated to have defense fluid with aversive smell (methoxypyrazines), body tissues with a…
Dialogioppiminen ryhmä- ja yksilötasoilla hoitotyön kontekstissa
2000
Artikkelissa dialogioppimista on tulkittu hoitotyön oppimisen ja opettamisen erilaisissa käytänteissä. Käsitys dialogista perustuu Bahtinin puheen teoriaan, jossa näkökulmien vastakkaisuutta pidetään dialogin syntymisen ehtona. Käsitys oppimisesta perustuu kontekstuaaliseen näkemykseen, jossa oppimisen kohteeksi rajataan arkitodellisuus ja sieltä nousevat ongelmat. Koska arjen ristiriitaiset käytänteet kiinnittyvät erilaisiin ajattelu- ja toimintamalleihin, puheesta on etsitty historiallisia ääniä, vakiintuneiksi muodostuneita hoitamisen ja oppimisen muotoja. Tarkoituksena on ollut selvittää, millaisten dialogien avulla näistä erilaisista äänistä rakennetaan jaettua ja yksilöllistä tietämys…
Habitat area and local habitat conditions outweigh fragmentation effects on insect communities in vineyards
2022
Fragmentation of habitat, for example by intensive agricultural practices, can be detrimental to local biodiversity. However, it often remains unclear whether such biodiversity declines are caused by loss of habitat area or increased fragmentation, and how habitat quality factors into it. In our study system, vegetated vineyards are typically small, and isolated from one another, potentially limiting the distribution and dispersal of organisms. In a full-factorial experiment of a priori selected vegetated vineyard patches of differing size and fragmentation, we aimed to disentangle the effects of habitat area (area of vegetated vineyards), habitat fragmentation (number of vegetated vineyard…
