Effect of being the organizer of a Handball Worl Championship in team perfomance
Cuando un equipo actúa como local parece tener cierta ventaja. Este hecho se denomina home advantage (HA) y ha sido muy estudiado en competiciones de liga, pero poco en competiciones de sede única. Se analizaron 4.340 partidos disputados en todos los Campeonatos del Mundo de balonmano disputados hasta 2011. Las variables registradas fueron: partidos ganados, empatados, perdidos, número goles marcados y recibidos y sexo de los competidores. La HA en los Campeonatos del Mundo de balonmano es de 67,9±0,23 para la categoría masculina y de 71,2±0,27 para la femenina. Existe una asociación entre la HA, los puntos obtenidos y la clasificación final del equipo.When a team plays at home seems to get some advantage. This effect is called home advantage (HA) and has been widely studied in league competitions, but little in competitions in a single venue. 4.340 games played in all Handballl World Championships since 1936 to 2011 were analyzed. The variables registered were games won, games drawn, games lost, the number of goals scored and goals against and the gender of the competitors. The HA (mean±sd) in the World Handball Championships is 67.9±0.23, for the male category and 71.2±0.27 for the female. A significant association exists between HA, the points obtained in a competition and the final classification of a team
Nuevo índice para evaluar anomalías de elementos traza en suelos: el caso del SE español
In this work, an index is established to detect anomalies in trace elements in the soil. This index, which relates the
total concentration of each element with the regional geochemical background value of the element considered, was
defined by studying the levels of trace elements from different soils located in SE Spain. In the area, a previous
screening of trace elements detected seven zones with anomalies and revealed two conflictive areas: Sierra Gador and
Cabo de Gata. In each zone, a second sampling was undertaken at two different depths (0-20 cm and 20-40 cm). The
results indicate that the main anomalies were due to arsenic (As), lead (Pb), and zinc (Zn). In Sierra Gador Pb was the
element that registered the highest rate of enrichment with respect to the regional geochemical background, reaching
values up to 270-fold higher in some samples. In this zone, more than 50% of the samples were anomalous in any of
the trace elements studied (higher than regional geochemical background). In Cabo de Gata, As concentration was
higher than the geochemical background in more than 40% of the samples; meanwhile Pb concentration was higher
in 50% of the samples.En este trabajo establecemos un índice para detectar anomalías en el contenido de elementos traza en suelos. Este índice relaciona el contenido total de cada elemento traza con el fondo geoquímico regional, definido mediante el estudio de los niveles de elementos traza en diferentes suelos localizados en el sureste español. En un primer estudio sobre niveles de elementos traza en suelos del área de estudio detectaron siete zonas con anomalías, de las cuales dos fueron consideradas conflictivas: Sierra de Gádor y Cabo de Gata. En cada una de estas dos zonas se realizó un segundo estudio más exhaustivo a dos niveles de profundidad (0-20 y 20-40 cm). Los resultados indican que las principales anomalías correspondes a los niveles de As, Pb y Zn. En Sierra de Gádor el Pb es el elemento que presenta una mayor tasa de enriquecimiento con respecto al fondo geoquímico regional, con valores puntuales que lo superan hasta 270 veces. También en esta zona más del 50% de las muestras presentan anomalías en alguno de los elementos analizados. En Cabo de Gata el As supera el fondo geoquímico regional en más del 40% de las muestras; mientras que el Pb lo supera en el 50% de las muestras.This study has been made possible by the research Project no. 1550 of the Regional Environmental Department of the Andalusian Government
Measuring home advantage in Spanish Football (1928-2011)
Pollard (1986) estableció el procedimiento para analizar la ventaja de jugar en casa, efecto que en términos anglosajones se denomina “home advantage” (HA). La HA ha sido estudiada en multitud de deportes, tanto individuales como de equipo, determinando su existencia y sus posibles causas. Este artículo analiza la HA de la primera división de fútbol español a lo largo de su historia (desde 1928 hasta el 2011). La muestra es de 80 temporadas y 22.015 partidos jugados en las competiciones de liga de máxima categoría española. La HA es de 70,8±0,14 en las máximas categorías del fútbol español en la época en la que el valor de la victoria era de dos puntos (1928-1995) y de 56,7±0,14 cuando se otorgan tres puntos por la victoria (1995-2011Pollard (1986) established the procedure for analyzing the home advantage (HA). The HA has been studied in many different sports, both individual and team sports, determining its existence and its possible causes. This article analyzes the HA of the first division of Spanish football across the history (from 1928 until 2011). The sample is of 80 seasons and 22015 games of the highest level in Spain. The HA (mean±sd) is of 70.8±0.14 in the highest category in Spanish football during the period when a victory was worth two points (1928-1995) and 56.7±0.14 when three points were awarded for a victory (1995-2011

Emotional Differences in Young and Older Adults: Films as Mood Induction Procedure
Film clips are proven to be one of the most efficient techniques in emotional induction. However, there is scant literature on the effect of this procedure in older adults and, specifically, the effect of using different positive stimuli. Thus, the aim of the present study was to examine emotional differences between young and older adults and to know how a set of film clips works as mood induction procedure in older adults, especially, when trying to elicit attachment-related emotions. To this end, we use this procedure to analyze differences in subjective emotional response between young and older adults. A sample of 57 older adults and 83 young adults watched a film set previously validated in young population. Their responses were studied in an individual laboratory session to elicit 6 target emotions (disgust, fear, sadness, anger, amusement and tenderness) and neutral state. Self-reported emotional experience was measured using the Self-Assessment Manikin (SAM). Our results show that film clips are capable of evoking positive and negative emotions in older adults. Furthermore, older adults experienced more intensely negative emotions than young adults, especially in response to disgust and fear clips. They also reported higher arousal than young adults, especially in the case of sadness, anger and tenderness clips. Nevertheless, the older adults recovered more easily from the effects of the emotion induction. The young adults reported higher arousal ratings than older adults in response to amusement film clips. On the other hand, this study reflects the importance of controlling the baseline state to study the real strength of mood induction. Overall, current data suggests significant differences occur in emotional response in adult age and that film clips are an effective tool for studying positive and negative emotions in aging research
Wild felid species richness affected by a corridor in the Lacandona forest, Mexico
Los efectos de la presencia de un corredor en la selva Lacandona, en México, en la riqueza de especies de félidos silvestres Los félidos silvestres se encuentran entre las especies más vulnerables ante la pérdida de hábitat causada por la fragmentación de los ecosistemas. Se analizó el efecto de la presencia de un corredor estructural, definido como una franja de vegetación que conecta dos fragmentos de hábitat, en la riqueza y ocupación de félidos en tres sitios de Marqués de Comillas, en Chiapas: uno comprende dos fragmentos de bosque aislados, otro presenta un corredor estructural y el último se encuentra dentro de la reserva de la biosfera Montes Azules. Se encontraron cuatro especies en el interior de la Reserva, cinco en el corredor estructural y únicamente dos (L. pardalis y H. yagouaroundi) en los fragmentos de bosque aislados. La presencia del corredor no afectó de forma significativa a la ocupación, pero debido a la baja tasa de detección, se necesita seguir investigando para descartar diferencias. Nuestros resultados resaltan la necesidad de manejar la conectividad del hábitat en los bosques remanentes para lograr la conservación de la comunidad de félidos en Marqués de Comillas, en Chiapas, México.Los efectos de la presencia de un corredor en la selva Lacandona, en México, en la riqueza de especies de félidos silvestres Los félidos silvestres se encuentran entre las especies más vulnerables ante la pérdida de hábitat causada por la fragmentación de los ecosistemas.

We analyzed the effect of a structural corridor, defined as a strip of vegetation connecting two habitat patches, on the richness and habitat occupancy of felids on three sites in Marqués de Comillas, Chiapas, one with two isolated forest patches, the second with a structural corridor, and the third inside the Montes Azules Biosphere Reserve. We found only two species (L. pardalis and H. yagouaroundi) in the isolated forest patches, five species in the structural corridor, and four species inside the Reserve. The corridor did not significantly affect occupancy, but due to the low detection rates, further investigation is needed to rule out differences. Our results highlight the need to manage habitat connectivity in the remaining forests in order to preserve the felid community of Marqués de Comillas, Chiapas, México
Functional diversity of ectomycorrhizal fungal communities is reduced by trace element contamination
10 páginas.-- 2 figuras.-- 3 tablas.-- 105 referencias.-- Supplementary data related to this article can be found at http://dx.doi.org/10.1016/j.soilbio.2018.03.021Trait-based approaches are useful tools to explain ecological assembly rules and ecosystem functioning. However, their use for soil microbiota has not been explored in depth yet. We explored trait-based functional changes of ectomycorrhizal (ECM) fungal communities associated with holm oak (Quercus ilex subsp. ballota) in a trace element contaminated area.
We found a variation in ECM fungal species composition determined by soil C, Ca and trace elements; however, taxonomic diversity was not dependant on contamination level. Mean trait values of ECM fungal communities showed less rhizomorph and emanating hyphae production when increasing contamination, and the community converged towards species developing rhizomorphs less frequently. We suggest that trace elements in soils acted as the main environmental filter of trait diversity of ECM fungal communities. The effect of soil nutrients, i.e. soil C, affected the community mean trait values of emanating hyphae but did not cause a convergence in its distribution.
In summary, we found a reduction in the functional diversity of ECM fungal communities due to trace element contamination with potential to affect ecosystem functioning. This finding supports the potential of trait-based approaches to assess changes in the functional diversity of soil microbial communities.This work was supported by European Union Seventh Framework Programme (FP7/2007–2013) [grant number 603498 - RECARE]; Spanish Ministry of Economy and Competitiveness [grant number CGL2014-52858-R - RESTECO]; Spanish National Research Programme - European Union (Feder) [grant number CGL2015-69118-C2-2-P - COEXMED-II].

Validation of the index for inclusion questionnaire for parents of non-university education students
The perspective from the parents of non-university students is essential in determining inclusive education in a school. The Index of Inclusion is one of the most widely used self-assessment tools and strategies to help teaching teams self-assess their political cultures and practices from the perspective of the values and principles of educational inclusion worldwide. For this reason, the present study intends to show evidence of validity of the Index for Inclusion questionnaire for parents of non-university education students, in a quantitative way, through a confirmatory factor analysis (CFA). In this study, 108 fathers and 500 mothers took part, aged between 21 and 62 years (M = 43.59; SD = 6.64), whose children belonged to educational institutions throughout Spain. The results revealed adequate adjustment rates, showing invariant structure with respect to sex. The Index for Inclusion for families of non-university education students was shown to be a robust and adequate psychometric instrument to assess the degree of development of inclusive education in educational institutions from the perspective of the parents of said student body. The family is a basic pillar in the education of children and a reference for them. In addition, parents of non-university education students are configured as fundamental participatory elements of the child’s educational institution thus; making the family a fundamental element that favors inclusive education. Precisely because of all this, the future administration of this questionnaire (to the parents of these students) is recommended
