Farm Entrepreneurs’ Intentions to Develop Pluriactive Business Activities in Finland
2015
We contribute to the entrepreneurial intentions literature by applying the theory of planned behaviour and resource-based views to the model of active entrepreneurs’ intention to develop their pluriactive businesses. Using our 2012 survey data from farm firms in Finland, we address the limited focus on active entrepreneurs and their intentions to develop on-going income-generating, off-farm related business activities. We found that attitudinal proxy antecedents such as innovation, cooperation and growth for pluriactivity differ for active and non-active entrepreneurs and with respect to the entrepreneurs’ age and production line and innovation behaviour.

Mismatch negativity (MMN) in freely-moving rats with several experimental controls.
2014
Mismatch negativity (MMN) is a scalp-recorded electrical potential that occurs in humans in response to an auditory stimulus that defies previously established patterns of regularity. MMN amplitude is reduced in people with schizophrenia. In this study, we aimed to develop a robust and replicable rat model of MMN, as a platform for a more thorough understanding of the neurobiology underlying MMN. One of the major concerns for animal models of MMN is whether the rodent brain is capable of producing a human-like MMN, which is not a consequence of neural adaptation to repetitive stimuli. We therefore tested several methods that have been used to control for adaptation and differential exogenou…
Modulation of the Endocannabinoids N-Arachidonoylethanolamine (AEA) and 2-Arachidonoylglycerol (2-AG) on Executive Functions in Human.
2013
Animal studies point to an implication of the endocannabinoid system on executive functions. In humans, several studies have suggested an association between acute or chronic use of exogenous cannabinoids (Δ9-tetrahydrocannabinol) and executive impairments. However, to date, no published reports establish the relationship between endocannabinoids, as biomarkers of the cannabinoid neurotransmission system, and executive functioning in humans. The aim of the present study was to explore the association between circulating levels of plasma endocannabinoids N-arachidonoylethanolamine (AEA) and 2-Arachidonoylglycerol (2-AG) and executive functions (decision making, response inhibition and cognit…
All-Possible-Couplings Approach to Measuring Probabilistic Context.
2013
From behavioral sciences to biology to quantum mechanics, one encounters situations where (i) a system outputs several random variables in response to several inputs, (ii) for each of these responses only some of the inputs may "directly" influence them, but (iii) other inputs provide a "context" for this response by influencing its probabilistic relations to other responses. These contextual influences are very different, say, in classical kinetic theory and in the entanglement paradigm of quantum mechanics, which are traditionally interpreted as representing different forms of physical determinism. One can mathematically construct systems with other types of contextuality, whether or not …
Might as well jump: Sound affects muscle activation in skateboarding
2014
The aim of the study is to reveal the role of sound in action anticipation and performance, and to test whether the level of precision in action planning and execution is related to the level of sensorimotor skills and experience that listeners possess about a specific action. Individuals ranging from 18 to 75 years of age - some of them without any skills in skateboarding and others experts in this sport - were compared in their ability to anticipate and simulate a skateboarding jump by listening to the sound it produces. Only skaters were able to modulate the forces underfoot and to apply muscle synergies that closely resembled the ones that a skater would use if actually jumping on a ska…
Validation of the Dutch eating behavior questionnaire for children (DEBQ-C) for use with Spanish children Validación del cuestionario holandés de com…
2011
Introduction: The Dutch Eating Behaviour Questionnaire for children was developed by Van Strien and Oosterveld (2008) to measure three different eating behaviors (emotional eating, restrained eating and external eating); it is an adaptation of the DEBQ for adults. Objective: The purpose of this study is to analyze the psychometric properties of the Dutch Eating Behavior Questionnaire for Children (DEBQ-C) with a Spanish sample. Method: The DEBQ-C was administered to 473 children (240 boys and 233 girls), from 10 to 14 years old. The sample included a Clinical Overweight Group (COG; n = 81) comprising children who were receiving weight loss treatments, a Non Clinical Overweight Group (NCOG, …
INTERVENTION IN SOCIAL SKILLS OF CHILDREN WITH AUTISTIC SPECTRUM DISORDER: A BIBLIOGRAPHICAL REVIEW
2018
The prevalence rates of autistic spectrum disorder (ASD) have increased markedly in recent years. ASD is increasingly present in schools and in society, so it is essential for us to know more about this disorder and the possibilities for intervention. The objective of this work is to carry out a bibliographic review of the articles published in recent years in relation to different intervention programs and techniques that have recently been used to work with children with ASD to train them in the difficulties that most define the disorder: social skills. The most important conclusions indicate that, despite the symptomatic diversity of children with ASD and their different characteristics …
Familia, profesorado e iguales: claves para el apoyo a las víctimas de acoso escolar
2011
El objetivo del presente estudio fue analizar las diferencias en ajuste psicológico en víctimas de acoso escolar en función de la calidad de sus relaciones con padres, profesores e iguales. En concreto, se compararon cuatro indicadores de ajuste psicológico (autoestima, ánimo depresivo, soledad y percepción de estrés) en víctimas con buena o mala comunicación con la madre, buena o mala comunicación con el padre, alta o baja percepción de ayuda del profesor, y alta o baja identificación con su grupo de iguales. La muestra inicial estuvo compuesta por 1795 adolescentes, entre 11 y 18 años (M = 14.2, DT = 1.68). Los resultados indicaron que las víctimas que mantenían mejores relaciones sociale…
ASSOCIATION BETWEEN FAMILY ENVIRONMENT AND THE BULLYING PHENOMENON AMONG SCHOOL-AGE CHILDREN: A SYSTEMATIC REVIEW
2019
There is a lack of evidence about the possible role of the family environment in the occurrence of the bullying phenomenon among school-age children. We carried out a systematic review of the literature to investigate the positive and negative family determinants associated with the bullying phenomenon. Potential classes of determinants - e.g. interparental conflict and/or parenting behaviours - were studied by searching peer-reviewed literature published between the January 2008 and December 2018 on PubMed/MEDLINE, SCOPUS and ISI Web of Science. At the end of the eligibility process, only 3 studies met all the inclusion criteria, and were then included in the narrative synthesis. Mother de…
Distribution and depletion of sulfadiazine after a multiple per os dosing in gilthead sea bream (Sparus aurata) fed two different diets
2013
The distribution and depletion profile of sulfadiazine (SDZ) were investigated in gilthead sea bream (Sparus aurata) fed on fish oil (FO) or plant oil-based (PO) diets. Fish averaging 230 g were given medicated feed containing 25 mg SDZ kg-1 fish for 5 days at 24-26°C. Blood and muscle plus skin were sampled on days 1, 3, 5, 6, 8 and 9. Differences in plasma and fillet SDZ levels between the two groups were statistically insignificant. The maximum drug concentrations in plasma were 3.2 ± 1.9 μg mL-1 and 2.9 ± 1.2 μg mL-1 in the PO and FO groups, respectively. In post-medicated samples depletion rapidly reached concentrations close to the level of quantification at 72 h post medication. With…
