Systematic review of prosocial behavior measures
2018
Measuring prosocial conduct, just as other constructs which are relevant for psychological adjustment, requires a base of knowledge which is orderly and up-to-date, which helps to identify and methodological aspects for its construction. The objective of this study is to identify the instruments for measuring prosocial behavior which are available today in the empirical literature, as well as to analyze their characteristics and psychometric properties.In this study, the bibliographic search was carried out on the databases of web of science (WOS) and Dialnet from 1900 to 2017 with special emphasis on the last decade. Sixteen instruments relevant to prosocial behavior were chosen describing…
Towards a framework for assessment and management of cumulative human impacts on marine food webs
2015
Effective ecosystem-based management requires understanding ecosystem responses to multiple human threats, rather than focusing on single threats. To understand ecosystem responses to anthropogenic threats holistically, it is necessary to know how threats affect different components within ecosystems and ultimately alter ecosystem functioning. We used a case study of a Mediterranean seagrass (Posidonia oceanica) food web and expert knowledge elicitation in an application of the initial steps of a framework for assessment of cumulative human impacts on food webs. We produced a conceptual seagrass food web model, determined the main trophic relationships, identified the main threats to the fo…

Intervenciones educativas que favorecen la autoestima en el alumnado de Educación Infantil y Educación Primaria: Una revisión sistemática
2022
La educación emocional y la autoestima son esenciales para el desarrollo integral de los niños y niñas, por ello son necesarios programas educativos eficaces en la escuela a edades tempranas. El objetivo de esta revisión sistemática es analizar las intervenciones que trabajan el fomento de la autoestima existentes en el ámbito de la Educación Infantil y Educación Primaria, y examinar cuál de ellas resultan más efectivas. Tras realizar la búsqueda de literatura en las bases de datos Psicodoc, PsycInfo y Eric, se incluyen 5 estudios que cumplen los criterios de inclusión en dicha revisión sistemática. Los resultados muestran un aumento significativo de la autoestima en el 80% de los programas…
Implementation and Outcomes of Lay Health Worker–led Self-management Interventions for Long-Term Conditions and Prevention: A Systematic Review
2019
The aim of this study was to systematically review lay health worker (LHW)–led self-management interventions for adults with long-term conditions to see how the interventions have been implemented and to compose a synthesis of research findings, taking into consideration the intervention components that have been applied. We conducted systematic searches for articles published between January 2010 and December 2015 in five databases: Cochrane, MEDLINE, CINAHL, PsycINFO, and Web of Science. Forty original studies were found that met the inclusion criteria: self-management with diabetes (n = 29), cardiovascular diseases (n = 8), and those at risk of cardiovascular diseases (n = 3). These cons…
The effects of grazing history, soil properties and stand structure on the communities of saprotrophic fungi in wood-pastures
2022
Wood-pastures are threatened anthropogenic biotopes that provide habitat for an extensive group of species. Here we studied the effect of management, grazing intensity, time since abandonment, historical land-use intensity, soil properties and stand conditions on communities of saprotrophic fungi in wood-pastures in Central Finland. We found that the proportion of broadleaved trees and soil pH are the major drivers in the communities of saprotrophic fungi in these boreal wood-pastures. In addition, tree species richness, soil moisture, historical land-use intensity and time since abandonment affected the communities of saprotrophic fungi. Current management or grazing intensity did not have…

Sex Allocation Theory for Facultatively Sexual Organisms Inhabiting Seasonal Environments: The Importance of Bet Hedging
2018
Adaptive explanations for dormancy often invoke bet hedging, where reduced mean fitness can be adaptive if it associates with reduced fitness variance. Sex allocation theory typically ignores variance effects and focuses on mean fitness. For many cyclical parthenogens, these themes become linked, as only sexually produced eggs undergo the dormancy needed to survive harsh conditions. We ask how sex allocation and the timing of sex evolve when this constraint exists in the form of a trade-off between asexual reproduction and sexual production of dormant eggs—the former being crucial for within-season success and the latter for survival across seasons. We show that male production can be tempo…
Kin selection in interactions between gametes: Gamete competition, gamete limitation, and sex allocation
2023
Kin selection on one hand, and gamete interactions in post-ejaculatory sexual selection on the other are two major research themes that have risen to prominence over the past half century and have simultaneously developed into central fields of research in evolutionary biology. There is a natural connection between the two: when gametes interact with each other, very commonly many of them originate from the same parent and are thus siblings. For example, sperm competition will almost always involve competition between sibling gametes even if the interacting parents are not related to each other. If parents are related to each other, the relatedness between gametes increases further. Here we…
New Gynandromorph Records for Chirocephalus diaphanus (Branchiopoda, Anostraca, Chirocephalidae)
2021
We report and describe new Chirocephalus diaphanus Prévost, 1803 gynandromorphs from Tunisia and review the literature of anostracan gynandromorphy and other, possibly associated, somatic aberrations, with comments on their evolutionary significance. Our material has three specimens that are specifically deformed on the left side of the head.
