Conducta agresiva e inteligencia emocional en la adolescencia

Son escasos los estudios que analizan la relación entre conducta agresiva e inteligencia emocional. Este estudio examina la relación entre inteligencia emocional rasgo y los componentes motor (agresividad física y agresividad verbal), cognitivo (hostilidad) y afectivo/emocional (ira) de la conducta agresiva. El Trait Emotional Intelligence Questionnaire-Adolescents Short Form (TEIQue-ASF) y el Aggression Questionnaire Short version (AQ-S) fueron administrados a una muestra de 314 adolescentes (52.5% chicos) de 12 a 17 años. Los resultados indicaron que los adolescentes con altas puntuaciones en conducta agresiva física, verbal, hostilidad e ira presentaron puntuaciones significativamente más bajas en inteligencia emocional rasgo que sus iguales con puntuaciones bajas en conducta agresiva física, verbal, hostilidad e ira. Este patrón de resultados fue el mismo tanto para la muestra total como para chicos, chicas y los grupos de edad de 12-14 años y 15-17 años. Además, en la mayoría de los casos se hallaron tamaños del efecto grandes apoyando la relevancia empírica de estas diferencias.

Perfil sociodemográfico del feminicidio en España y su relación con las denuncias por violencia de pareja

Objetivo: Analizar las características asociadas al riesgo de feminicidio en España entre mujeres expuestas a la violencia de pareja o análogo y su posible asociación con las denuncias a los agresores. Métodos: Se realizó un estudio de casos y controles para el periodo 2010-2011. Los casos, 135 mujeres mayores de edad, asesinadas por su pareja o análogo durante dicho periodo, se identificaron a través de la página web de la Federación de Asociaciones de Mujeres Separadas y Divorciadas, y de los informes del Consejo General del Poder Judicial. Los controles, 185 mujeres expuestas a la violencia de pareja el último año, proceden de la Macroencuesta de Violencia de Género 2011. La asociación entre la denuncia y el riesgo de feminicidio se estimó mediante modelos de regresión logística multivariada. Resultados: No se encontró asociación entre denunciar al agresor y el riesgo de ser asesinada (odds ratio [OR]: 1,38; intervalo de confianza del 95% [IC95%]: 0,68-2,79). Las mujeres inmigrantes expuestas a la violencia de pareja registraron una mayor probabilidad de ser asesinadas (ref.: mujeres españolas; OR: 5,38; IC95%: 2,41-11,99). Esta asociación también se observó en las mujeres que vivían en zonas rurales (ref: zonas urbanas; OR: 2,94; IC95%: 1,36-6,38). Conclusiones: La denuncia judicial al agresor no parece modificar el riesgo de asesinato entre las mujeres expuestas a la violencia de pareja. Las medidas de protección a las mujeres deberían extremarse en las mujeres inmigrantes y las que viven en el medio rural.

The harsh reality of Ukraine's fiscal arithmetic. Bruegel Policy Contribution ISSUE 2015/07, June 2015

Ukraine is struggling with both external aggression and the dramatically poor shape of its economy. The pace of political and institutional change has so far been too slow to prevent the deepening of the fiscal and balance-of-payments crises, while business confidence continues to be undermined. • Unfortunately, the 2015 International Monetary Fund Extended Fund Facility programme repeats many weaknesses of the 2014 IMF Stand-by Arrangement: slow pace of fiscal adjustment especially in the two key areas of energy prices and pension entitlements, lack of a comprehensive structural and institutional reform vision, and insufficient external financing to close the expected balance-of-payments gap and allow Ukraine to return to debt sustainability in the long term. • The reform process in Ukraine must be accelerated and better managed. A frontloaded fiscal adjustment is necessary to stabilise public finances and the balance-of-payments, and to bring inflation down. The international community, especially the European Union, should offer sufficient financial aid backed by strong conditionality, technical assistance and support to Ukraine’s independence and territorial integrity.

An adaptogenic role for omega-3 fatty acids in stress; a randomised placebo controlled double blind intervention study (pilot) [ISRCTN22569553]

Background There is evidence for an adaptive role of the omega -3 fatty acid, docosahexaenoic acid (DHA) during stress. Mechanisms of action may involve regulation of stress mediators, such as the catecholamines and proinflammatory cytokines. Prevention of stress-induced aggression and hostility were demonstrated in a series of clinical trials. This study investigates whether perceived stress is ameliorated by DHA in stressed university staff. Methods Subjects that scored ≥ 17 on the Perceived Stress Scale were randomised into a 6-week pilot intervention study. The diet reactive group was supplemented with 6 g of fish oil containing 1.5 g per day DHA, while the placebo group was supplemented with 6 g a day of olive oil. The groups were compared with each other and a wider cross sectional study population that did not receive either active or placebo intervention. Results There was a significant reduction in perceived stress in both the fish oil and the placebo group from baseline. There was also a significant between-group difference between the fish oil group and the no-treatment controls in the rate of stress reduction (p < 0.05). However, there was not a significant between-group difference between the fish oil and the placebo group, nor the placebo group and the control group. These results are discussed in the context of several methodological limitations. The significant stress reductions in both the fish oil and the placebo group are considered in view of statistical regression, an effect likely to have been exaggerated by the time course of the study, a large placebo effect and the possibility of an active effect from the placebo. Conclusion There were significant differences (p < 0.05) in the fish oil group compared with no-treatment controls. This effect was not demonstrated in the placebo group. As a pilot study, it was not sufficiently powered to find the difference between the fish oil group and the placebo group significant. Further work needs to be undertaken to conclusively demonstrate these data trends. However, the findings from this research support the literature in finding a protective or 'adaptogenic' role for omega-3 fatty acids in stress.

Approach to challenging behaviour: a family affair

Over the past 30 years, research in the area of applied behaviour. analysis has led to a rich knowledge and understanding of the variables that influence human behaviour. This understanding and knowledge has given rise to a range of assessment and intervention techniques that have been applied to individuals with challenging behaviour. Interventions have produced changes in the severity and frequency of behaviours such as self-injury, aggression, and property destruction, card have also led to the acquisition of desired behaviours. While behaviour change has been achieved, families have expressed a desire for positive behaviour support approaches that adopt a family,focus. Research and development of support frameworks that emphasise the interrelatedness of family members, and the child with a disability as part of his or her family, have gained prominence in the family systems literature. The present paper reviews some of the behaviourally based research in this area. Through the use of a case illustration, the authors discuss the links between behavioural support and family-centred support systems for children with developmental disabilities. Theoretical and practical implications are considered and areas for future research are highlighted.

Preferência e competição alimentar em um grupo de Sapajus flavius em fragmento de Mata Atlântica em Caaporã – Paraíba – Brasil

Feeding is the primary selective pressure in all forms of animals. Nutritional ecological models predict consequences of preferred and non-preferred food consumption on behavioural, physiological and morphological adaptations. At same time, socioecological models infer socio-organizarion patterns based on feeding competition faced by animals. A list of preferred foods, and inferences regarding the intensity of feeding competition and its behavioural consequences are information of much importance for management of populations in fragments. In this work we observed the feeding behavior and spatial positioning of a group of more than 100 blond capuchin monkeys (Sapajus flavius) that inhabit a fragment of Atlantic forest, surrounded by sugarcane plantation. We compared the consumption of different food items with their monthly availability in the area to define the preferred and fallback food items. We recorded the vocalizations of aggression and the inter-individual distance (area of Minimum Convex Polygon/n individuals) to infer the type of food competition experienced by animals. In the year studied the fruit feeding time correlated with top consumed fruit productivity, indicating preference for fruits. Our data indicate that the species Elaeis sp., Cecropia palmata, Inga spp. and Simarouba amara are the preferred food items in the diet. Available all year round and uniformly distributed, sugarcane was a regular item in the diet and its was characterized as a staple fallback food for this group. Although fruits are preferential food items, direct competition rate did not correlate to fruit productivity in the area, maintaining the high rates throughout the year (2.45 events/ hour). The inter-individual distance index positively correlated with rain fall indicating scramble food competition. The number of neighbours of females carrying infants was smaller when fruit productivity is low, indicating that females carrying infants are suffering increased indirect competition. Our data indicates that blond capuchins in this fragment make use of sugar cane as a staple fallback food, which evidence the importance of sugar cane landscape for the survival of this critically endangered capuchin species in fragmented habitats in Northeast Brazil. A preliminary list of preferred and important foods is offered, and can assist in the choice of trees for reforestation, better fragments to be preserved and areas of release and translocation of animals. We did not observe an increase of contest competition while using preferred foods, but when using staple FBF. This may be due the altered environment, which results in high competition food throughout the year. Both the food preference as the social and behavioral consequences of high food competition experienced by animals in this fragment must be accompanied over the years to ensure the survival of this population.

Frontline employees’ innovative service behavior as key to customer loyalty:insights into FLEs’ resource gain spiral

Many service firms require frontline service employees (FLEs) to follow routines and standardized operating procedures during the service encounter, to deliver consistently high service standards. However, to create superior, pleasurable experiences for customers, featuring both helpful services and novel approaches to meeting their needs, firms in various sectors also have begun to encourage FLEs to engage in more innovative service behaviors. This study therefore investigates a new and complementary route to customer loyalty, beyond the conventional service-profit chain, that moves through FLEs' innovative service behavior. Drawing on conservation of resources (COR) theory, this study introduces a resource gain spiral at the service encounter, which runs from FLEs' emotional job engagement to innovative service behavior, and then leads to customer delight and finally customer loyalty. In accordance with COR theory, the proposed model also includes factors that might hinder (customer aggression, underemployment) or foster (colleague support, supervisor support) FLEs' resource gain spiral. A multilevel analysis of a large-scale, dyadic data set that contains responses from both FLEs and customers in multiple industries strongly supports the proposed resource gain spiral as a complementary route to customer loyalty. The positive emotional job engagement-innovative service behavior relationship is undermined by customer aggression and underemployment, as hypothesized. Surprisingly though, and contrary to the hypotheses, colleague and supervisor support do not seem to foster FLEs' resource gain spiral. Instead, colleague support weakens the engagement-innovative service behavior relationship, and supervisor support does not affect it. These results indicate that if FLEs can solicit resources from other sources, they may not need to invest as many of their individual resources. In particular, colleague support even appears to serve as a substitute for FLEs' individual resource investments in the resource gain spiral.

The Online Romance Scam: A Serious Cybercrime

The Online Romance Scam is a relatively new form of fraud that became apparent in about 2008. In this crime, criminals pretend to initiate a relationship through online dating sites then defraud their victims of large sums of money. This paper presents some descriptive statistics about knowledge and victimization of the online dating romance scam in Great Britain. Our study found that despite its newness, an estimated 230,000 British citizens may have fallen victim to this crime. We conclude that there needs to be some rethinking about providing avenues for victims to report the crime or at least making them more comfortable when doing so.

Effekter av icke-farmakologiska metoder vid beteendemässiga och psykiska symtom hos personer som lever med Alzheimers sjukdom : En litteraturöversikt

Bakgrund: Alzheimers sjukdom (AD) är den vanligaste formen av demenssjukdomar och antalet människor som insjuknar i AD förväntas öka kraftigt med tiden. Dessutom kännetecknas personer med AD ofta av beteendemässiga och psykiska symtom (BPSD) som kan innefatta agitation, depression, vanföreställningar, oro, ångest, hallucinationer, sömnrubbningar, rastlöshet och apati. Dessa symtom kan orsaka lidande hos patienten och är svåra att hantera för både vårdgivaren och anhöriga, samt försvårar omvårdnadsarbetet. Syftet var att beskriva icke-farmakologiska metoder och effekter av dessa metoder vid omvårdnad av personer med Alzheimers sjukdom som har beteendemässiga och psykiska symtom. Metod: En litteraturöversikt bestående av 16 utvalda kvantitativa forskningsartiklar har genomförts. Artiklarna publicerades mellan år 2006-2016. Resultat. De studerade icke-farmakologiska metoderna var musikterapi, vissa typer av massage, reminiscence-terapi, vårdhundterapi och ljusterapi. Resultaten visade att icke-farmakologiska metoder kan ha en varierande effekt på BPSD. Litteraturöversikten visade att musikintervention var mest effektiv för att minska agitationsbeteende. Individualiserad musik i samband med speciella minnen minskade stress, fobier hos personer med svår demens. Intervention av handmassage, aromaterapi, taktil massage och terapeutisk beröring minskade aggression och agitationsbeteende. Vissa studier visade dock att fotmassageintervention och vårdhundterapi kunde öka verbal aggressivitet hos personer med demens, medan en annan studie visade att djurassisterade aktiviteter kunde minska nedstämdhet medan glädje och generell uppmärksamhet ökade. Effekten av ljusbehandling var förbättrad sömn, minskad depression, agitation och ätstörningar. Slutsats. Icke-farmakologiska metoder kan minska beteendemässiga och psykiska symtom hos personer med Alzheimers sjukdom, dock med varierande effekt. De varierande resultaten kan tolkas som att icke-farmakologiska metoder bör individanpassas och att det behövs vidare forskning inom området.

Fragebogen zur Erfassung von Störungen im Unterricht: die Faktorenstruktur der Schülerinnen- und Schülerversion

In diesem Beitrag wird ein neu entwickelter Schülerinnen- und Schülerfragebogen zur Erfassung aggressiver und nicht aggressiver Schülerstörungen, aggressiven Lehrerverhaltens, Störungen des methodisch-didaktischen Settings sowie Klassenführung und Beziehung vorgestellt und die testtheoretischen Kennwerte diskutiert. Die faktorielle Struktur wurde an einer Stichprobe von N=1341 Schülerinnen und Schüler der fünften und sechsten Klasse ermittelt. Eine explorative Faktorenanalyse mit Oblimin-Rotation ergab sieben eindeutige, gut interpretierbare Faktoren, welche den theoretisch postulierten Konstrukten entsprechen. Vier Faktoren erfassen Störungen und drei Faktoren umfassen störungspräventive Merkmale des Unterrichts. Die internen Konsistenzen der Skalen liegen zwischen .60 und .88. (DIPF/Orig.)

Physiological Effects of Alcohol on Crayfish Escape Circuitry

Alcohol is one of the oldest and most widely used drugs on the planet, but the cellular mechanisms by which it affects neural function are still poorly understood. Unlike other drugs of abuse, alcohol has no specific receptor in the nervous system, but is believed to operate through GABAergic and serotonergic neurotransmitter systems. Invertebrate models offer circuits of reduced numerical complexity and involve the same cell types and neurotransmitter systems as vertebrate circuits. The well-understood neural circuits controlling crayfish escape behavior offer neurons that are modulated by GABAergic inhibition, thus making tail-flip circuitry an effective circuit model to study the cellular mechanisms of acute alcohol exposure. Crayfish are capable of two stereotyped, reflexive escape behaviors known as tail-flips that are controlled by two different pairs of giant interneurons, the lateral giants (LG) and the medial giants (MG). The LG circuit has been an established model in the neuroscience field for more than 60 years and is almost completely mapped out. In contrast, the MG is still poorly understood, but has important behavioral implications in social behavior and value-based decision making. In this dissertation, I show that both crayfish tail-flip circuitry are physiologically sensitive to relevant alcohol concentrations and that this sensitivity is observable on the single cell level. I also show that this ethyl alcohol (EtOH) sensitivity in the LG can be changed by altering the crayfish’s recent social experience and by removing descending inputs to the LG. While the MG exhibits similar physiological sensitivity, its inhibitory properties have never been studied before this research. Through the use of electrophysiological and pharmacological techniques, I show that the MG exhibits many similar inhibitory properties as the LG that appear to be the result of GABA-mediated chloride currents. Finally, I present evidence that the EtOH-induced changes in the MG are blocked through pre-treatment of the potent GABAA receptor agonist, muscimol, which underlines the role of GABA in EtOH’s effects on crayfish tail-flip circuitry. The work presented here opens the way for crayfish tail-flip circuitry to be used as an effective model for EtOH’s acute effects on aggression and value-based decision making.

Ansiedad escolar según género y edad en una muestra de adolescentes chilenos

La ansiedad constituye un factor de riesgo para el bienestar y el desarrollo personal, social y académico de niños y adolescentes. Altos niveles de ansiedad reducen la eficiencia en el aprendizaje, ya que disminuyen la atención, la concentración y la retención, con el consecuente deterioro en el rendimiento escolar. Las investigaciones muestran altas tasas de prevalencia de ansiedad en población adolescente, especialmente en las mujeres. El objetivo del estudio es analizar la ansiedad escolar en una muestra de adolescentes chilenos según género y edad. Participaron 673 adolescentes, estudiantes de 6 colegios de la provincia de Ñuble, cuyo rango de edad es de 13 a 17 años (M = 15, 26; DE = 1, 32). La Ansiedad Escolar se evaluó con el Inventario de Ansiedad Escolar (IAES) que evalúa tres sistemas de respuesta; ansiedad cognitiva, ansiedad conductual y ansiedad psicofisiológica, y tres factores situacionales: ansiedad ante la evaluación social, ansiedad ante el fracaso escolar, y ansiedad ante la agresión. Los hombres presentaron puntuaciones menores que las mujeres, siendo las diferencias estadísticamente significativas en todos los sistemas de respuesta y en todos los factores situacionales. En los grupos de edad, las diferencias significativas se presentaron en el sistema de respuesta cognitivo, en dos factores situacionales (ansiedad ante el fracaso escolar y ansiedad ante la agresión) y en la puntuación total. El grupo de varones de 17 años fue quien presentó menores niveles de ansiedad escolar.

De la maltraitance à l’enfance aux comportements d’agression à l’âge adulte : quel est le rôle de la réactivité émotionnelle et comportementale?

En dépit des efforts déployés pour diminuer la prévalence de la maltraitance à l’enfance, celle-ci serait associée à des difficultés non négligeables, dont la manifestation d’agression. La réactivité émotionnelle et comportementale, incluant la colère, la peur et l’évitement, est proposée comme mécanisme expliquant la relation unissant la maltraitance à l’agression. Quatre objectifs sont poursuivis à cette fin, soit d’examiner la relation notée entre: (1) la maltraitance et l’agression, (2) la maltraitance et la colère, la peur, ainsi que l’évitement, (3) la colère, la peur, ainsi que l’évitement et l’agression et (4) tester formellement le rôle médiateur et modérateur de la colère, la peur et l’évitement à cette relation. Les données de 160 hommes âgés de 18 à 35 ans ayant été exposés ou non à de la maltraitance ont été colligées par le biais de questionnaires et d’une tâche de provocation sociale permettant de mesurer les expressions faciales de colère et de peur, ainsi que les comportements d’évitement. Les résultats suggèrent que la maltraitance et les comportements d’évitement sont associés à l’agression. La maltraitance ne serait toutefois pas liée à la colère, à la peur et à l’évitement. Alors que les résultats suggèrent que ces indices n’aient pas de rôles médiateurs dans la relation entre la maltraitance et l’agression, la réactivité aux plans de la colère et de l’évitement magnifierait cette relation. Ainsi, les résultats invitent à prendre en compte les expériences de maltraitance et l’intensité de la réactivité émotionnelle et comportementale dans les interventions afin de cibler les individus plus à risque d’avoir recours à l’agression.
