Decision-making Styles in Adolescent Offenders and Non-offenders: Effects of Emotional Intelligence and Empathy
2021
The literature indicates that adolescents with delinquent behavior have greater difficulty making rational decisions and show lower emotional intelligence and empathy. Decision-making is a set of complex processes associated with neurobiological, cognitive, emotional, and social factors which help regulate and guide behavior, which could be influenced by emotional intelligence and empathy. A comparative, correlational, and predictive study was conducted to analyze relationships and influence of emotional intelligence and empathy in decision-making styles in adolescent offenders and non-offenders. 808 Colombian adolescents between 14 and 18 years of age participated (50p offenders). The resu…
Critiquing and Joining Intersections of Disaster, Conflict, and Peace Research
2020
AbstractDisaster research, conflict research, and peace research have rich and deep histories, yet they do not always fully intersect or learn from each other, even when they investigate if and how disasters lead to conflict or peace. Scholarship has tended to focus on investigating causal linkages between disaster (including those associated with climate change) and conflict, and disaster diplomacy emerged as a thread of explanatory research that investigates how and why disaster-related activities do and do not influence peace and conflict. However, definitive conclusions on the disaster-conflict-peace nexus have evaded scientific consensus, in part due to conceptual, methodological, and …
Egg parasitoid attraction toward induced plant volatiles is disrupted by a non-host herbivore attacking above or belowground plant organs.
2014
Plants respond to insect oviposition by emission of oviposition-induced plant volatiles (OIPVs) which can recruit egg parasitoids of the attacking herbivore. To date, studies demonstrating egg parasitoid attraction to OIPVs have been carried out in tritrophic systems consisting of one species each of plant, herbivore host, and the associated egg parasitoid. Less attention has been given to plants experiencing multiple attacks by host and non-host herbivores that potentially could interfere with the recruitment of egg parasitoids as a result of modifications to the OIPV blend. Egg parasitoid attraction could also be influenced by the temporal dynamics of multiple infestations, when the same …
Satisfacción con la Vida y Factores Asociados en una Muestra de Menores Infractores
2018
El objetivo de esta investigación es, por un lado, conocer la relación existente entre el apoyo social percibido, la empatía emocional y cognitiva, la satisfacción con la vida, la expresión de ira como rasgo y cinco dimensiones del autoconcepto −académico, social, emocional, familiar y físico− en una muestra de residentes en un centro de reeducación de menores infractores en cumplimiento de medidas judiciales. Por otro lado, el trabajo pretende conocer cuáles son las variables que mejor predicen la satisfacción con la vida en la misma muestra. Los principales resultados son la existencia de correlaciones positivas de satisfacción con la vida con apoyo social y autoconcepto, así como que el …
Persistent traffic offenders. Alcohol consumption and personality as predictors of driving disqualification
2019
espanolLa seguridad vial es un importante problema social. Muchos accidentes se deben al incumplimiento de las normas de trafico. Las infracciones graves o reiteradas se sancionan por la via administrativa o judicial y en ambos casos las sanciones pueden suponer la perdida del permiso de conducir. Este articulo explora la relevancia del alcohol y la personalidad como factores predictivos. El objetivo del estudio es determinar si el comportamiento delictivo de los infractores persistentes esta relacionado con sus caracteristicas de personalidad y patrones de consumo de alcohol. Se utilizo una muestra de 358 conductores: 232 infractores persistentes, a los que les habia sido retirado el carne…
Data from: How to fight multiple enemies: target-specific chemical defences in an aposematic moth
2017
Animals have evolved different defensive strategies to survive predation, among which chemical defences are particularly widespread and diverse. Here we investigate the function of chemical defence diversity, hypothesising that such diversity has evolved as a response to multiple enemies. The aposematic wood tiger moth (Arctia plantaginis) displays conspicuous hindwing colouration and secretes two distinct defensive fluids, from their thoracic glands and abdomen. We presented fluids from lab-reared moths to two biologically relevant predators, birds and ants, and measured their reaction in controlled bioassays (no information on colour was provided). We found that defensive fluids are targe…
Data from: Dynamic transmission, host quality and population structure in a multi-host parasite of bumble bees
2012
The evolutionary ecology of multi-host parasites is predicted to depend upon patterns of host quality and the dynamics of transmission networks. Depending upon the differences in host quality and transmission asymmetries, as well as the balance between intra- and inter-specific transmission, the evolution of specialist or generalist strategies is predicted. Using a trypanosome parasite of bumble bees we ask how host quality and transmission networks relate to parasite population structure across host species, and thus the potential for the evolution of specialist strains adapted to different host species. Host species differed in quality, with parasite growth varying across host species. Hi…
Data from: Multi-modal defenses in aphids offer redundant protection and increased costs likely impeding a protective mutualism
2018
1.The pea aphid, Acyrthosiphon pisum, maintains extreme variation in resistance to its most common parasitoid wasp enemy, Aphidius ervi, which is sourced from two known mechanisms: protective bacterial symbionts, most commonly Hamiltonella defensa, or endogenously encoded defenses. We have recently found that individual aphids may employ each defense individually, occasionally both defenses together, or neither. 2.In field populations, Hamiltonella-infected aphids are found at low to moderate frequencies and while less is known about the frequency of resistant genotypes, they show up less often than susceptible genotypes in field collections. To better understand these patterns, we sought t…
Data from: The cotton stainer's gut microbiota suppresses infection of a co-transmitted trypanosomatid parasite
2018
The evolutionary and ecological success of many insects is attributed to mutualistic partnerships with bacteria that confer hosts with novel traits including food digestion, nutrient supplementation, detoxification of harmful compounds and defense against natural enemies. Dysdercus fasciatus firebugs (Hemiptera: Pyrrhocoridae), commonly known as cotton stainers, possess a simple but distinctive gut bacterial community including B-vitamin supplementing Coriobacteriaceae symbionts. In addition, their guts are often infested with the intestinal trypanosomatid parasite Leptomonas pyrrhocoris (Kinetoplastida: Trypanosomatidae). In this study, using experimental bioassays and fluorescence in situ…
Data from: De novo synthesis of chemical defences in an aposematic moth
2019
Many animals protect themselves from predation with chemicals, both self-made or sequestered from their diet. The potential drivers of the diversity of these chemicals have been long studied, but our knowledge them, and their acquisition mode, is heavily based on specialist herbivores that sequester their defences. The wood tiger moth (Arctia plantaginis, Linnaeus, 1758) is a well-studied aposematic species, but the nature of its chemical defences has not been fully described. Here we report the presence of two methoxypyrazines, 2-sec-butyl-3-methoxypyrazine and 2-isobutyl-3-methoxypyrazine, in the moths’ defensive secretions. By raising larvae on an artificial diet, we confirm, for the fir…
