Reliability of the spanish version of Questionnaire of Physical Activity PAQ-C

Objetivo. El objetivo de esta investigación ha sido valorar en niños españoles la fiabilidad del cuestionario de actividad física en niños mayores (PAQ-C). Método. Se utilizó como referencia la validación de la versión traducida al castellano del cuestionario de actividad física para adolescentes PAQ-A. En una muestra de 72 niños entre 8 y 14 años, se evaluó la fiabilidad test-retest del cuestionario PAQ-C en 3 mediciones, antes de la clase de educación física (M1), 2 horas después (M2) y al cabo de una semana (M3). La fiabilidad se calculó mediante el coeficiente de correlación intraclase (ICC) y la consistencia interna mediante el Coeficiente α de Cronbach. Resultados: Los valores obtenidos en la puntuación total del cuestionario reflejan un ICC superior a 0.73 en todas las comparaciones, con un intervalo de confianza al 95% que sigue indicando una fiabilidad buena o excelente. La consistencia interna mostró un coeficiente de α = 0,83Background: The aim of this study was to assess the reliability of the PAQ-C questionnaire in spanish older children (PAQ-C). Methods: A proof translation in Spanish of the physical activity questionnaire for teenager PAQ-A, was used as reference. Reliability of the test-retest questionnaire PAQ-C, was evaluated on 72 children aged between 8 and 14 years. Measurements were taken at three different stages: before the physical education class (M1), 2 hours after the lecture (M2) and one week later (M3). Reliability was calculated using the intraclass correlation coefficient (ICC) while the inner consistency by Cronbach's αcoefficient. Results: The results obtained in the overall score of the questionnaire reflect an intraclass coefficient (ICC) higher than 0,73 in every possible comparison giving a confidence interval of 95% which still indicates a good or very good reliability. The inner consistency showed a coefficient of α = 0,8

Attachment and substance use in adolescence: A review of conceptual and methodological aspects

Attachment is currently considered one of the major risk and/ or protective factors for substance use in adolescence. This paper reviews the most important studies published in the last 30 years in this field, focusing on the conceptual and methodological issues that may be making it more difficult to draw conclusions about the impact of attachment – especially attachment to parents – on substance use among youths. In general, the results indicate that secure attachment or stronger attachment between parents and children acts as a protective factor against drug use, even though there is a great variability in relation to the concept of addiction and its assessment. Secondly, most of the research reviewed also covers other factors that may be conditioning the influence of attachment to parents on children’s drug use and which would explain, at least in part, the disparity of the results from different studies. Notable among such factors would be individual characteristics (such as sex, age or self-esteem) and the influence of other sources of attachment, including peers and their circumstances (such as their drug use). Finally, we discuss the importance of taking into account the mentioned conceptual and methodological considerations aspects in research on attachment as a risk and/or protective factor for drug use in adolescence. El apego se considera actualmente uno de los mayores factores de riesgo y/o protección para el consumo de sustancias en la adolescencia. El presente trabajo revisa los estudios más importantes que se han publicado en los últimos 30 años al respecto, centrándose en aquellas cuestiones conceptuales y metodológicas que pueden estar dificultando concluir qué impacto ejerce el apego, sobre todo el apego a los padres, en el consumo de sustancias de los jóvenes. Los resultados indican, en general, que el apego seguro o un mayor apego entre padres e hijos actúa como factor de protección frente al consumo de drogas, si bien existe una gran variabilidad en torno al concepto de apego y su evaluación. En segundo lugar, la mayor parte de los estudios revisados incluyen además otros factores que pueden estar condicionando la influencia del apego a los padres en el consumo de drogas de los hijos y que explicarían, al menos en parte, la disparidad de los resultados en los distintos estudios. Entre estos factores destacarían las características individuales (como el sexo, la edad o la autoestima de los individuos), y la influencia de otras fuentes de apego, como los iguales y sus circunstancias, como por ejemplo el consumo de drogas por parte de éstos. Finalmente, se discute la importancia de tener en cuenta dichas consideraciones conceptuales y metodológicas en la investigación del apego como factor de riesgo y/o protección frente al consumo de drogas en la adolescencia

Survey data on joint cropland management among agri-food cooperatives in Mediterranean Spanish Regions

[EN] This dataset presents data collected from joint cropland management practices survey in agri-food cooperatives of Mediterranean Spanish Regions. The objective was to examine to what extent cooperatives offer joint services, including joint management or integral exploitation of smallholdings, for the incorporation of new professionals. Data collection was conducted to five agri-food organizations: three agri-food cooperatives federations -Castilla-La Mancha, Comunitat Valenciana, and Murcia-, two second-degree agri-food cooperatives -Anecoop and Unió Nuts-, all of them located in Mediterranean Spanish Regions. A total of 1.168 survey questionnaires were distributed between July 2020 and February 2021 across five organizations through the snowball sampling method. Data from 112 collected questionnaires were correctly answered, but 106 were selected for analysis. The dataset includes socioeconomic data, productive information, and innovative characteristics from agri-food cooperatives surveyed, all in order to be able to examine the relationship between those factors and joint cropland management practices they carry on.This work was supported by a grant for the implementation of innovation projects of general interest by operational groups of the European Innovation Partnership for Agricultural productivity and Sustainability (EIP-AGRI), within the 2019 call for submeasure 16. 2 (80% co-financed by the European Agricultural Fund for Rural Development (EAFRD) and by the General State Administration of the Government of Spain in 20%), within the National Program for Rural Development 2014-2020 (PNDR).Calafat Marzal, C.; Cervera, FJ.; Piñeiro, V.; Nieto-Alemán, PA.

The ability of a barotropic model to simulate sea level extremes of meteorological origin in the Mediterranean Sea, including those caused by explosive cyclones

Storm surges are responsible for great damage to coastal property and loss of life every year. Coastal management and adaptation practices are essential to reduce such damage. Numerical models provide a useful tool for informing these practices as they simulate sea level with high spatial resolution. Here we investigate the ability of a barotropic version of the HAMSOM model to simulate sea level extremes of meteorological origin in the Mediterranean Sea, including those caused by explosive cyclones. For this purpose, the output of the model is compared to hourly sea level observations from six tide gauge records (Valencia, Barcelona, Marseille, Civitavecchia, Trieste, and Antalya). It is found that the model underestimates the positive extremes significantly at all stations, in some cases by up to 65%. At Trieste, the model can also sometimes overestimate the extremes significantly. The differences between the model and the residuals are not constant for extremes of a given height, which limits the applicability of the numerical model for storm surge forecasting because calibration is difficult. The 50 and 10 year return levels are reasonably well captured by the model at all stations except Barcelona and Marseille, where they are underestimated by over 30%. The number of exceedances of the 99.9th and 99.95% percentiles over a period of 25 years is severely underestimated by the model at all stations. The skill of the model for predicting the timing and value of the storm surges seems to be higher for the events associated with explosive cyclones at all stations

Slope Instability along the northeastern Iberian and Balearic continental margins

This paper gathers the available information on submarine landslides identified in the northeastern Iberian continental margin and presents new data on both already known landslides and new, previously unknown ones. The 2,000 km2, 26 km3 resulting deposit of the BIG’95 debris flow in the Ebro margin; the 4 up to 16 km2, 0.4 km3 Eivissa slides in the Eivissa Channel; the 2 up to 65.6 km2, 1.46 km3 Barcelona slides in the shallow southern Catalan margin; and the western Gulf of Lions debris flow in the deep north Catalan margin are presented. This compilation is completed with several other previously undescribed small-scale mass-wasting deposits together with those observed in the Balearic Promontory. The amount and widespreading of submarine landslide deposits in the northern Iberian margins demonstrate that these margins are not an exception to the common occurence of these kind of structures worldwide, and gives an idea on this phenomena recurrence even in margins considered moderately quiet, in terms of seismicit

Los sedimentos de la plataforma continental balear

El anáiisis sedimentológico de distintos sectores de la plataforma continental balear (Bahia de Campos, Sur de Menorca y Canal de Menorca) ha puesto de manifiesto la existencia de siete grupos de facies: A) algales, B) de bivalvos, C) de gasterópodos, D) bioclásticas, E) mixtas, F) de fragmentos liticos y G) cementadas (costras algales y calcarenitas). La distribución de estas facies sedimentarias guarda una estrecha relacibn con la profundidad, excepto en el Sur de Menorca, y con las comunidades bentónicas que se desarrollan en la plataforma continental. Las facies que recubren actualmente la plataforma balear se depositaron durante la fase del ascenso del nivel del mar de la transgresión Versiliense

Improving sea level simulation in Mediterranean regional climate models

For now, the question about future sea level change in the Mediterranean remains a challenge. Previous climate modelling attempts to estimate future sea level change in the Mediterranean did not meet a consensus. The low resolution of CMIP-type models prevents an accurate representation of important small scales processes acting over the Mediterranean region. For this reason among others, the use of high resolution regional ocean modelling has been recommended in literature to address the question of ongoing and future Mediterranean sea level change in response to climate change or greenhouse gases emissions. Also, it has been shown that east Atlantic sea level variability is the dominant driver of the Mediterranean variability at interannual and interdecadal scales. However, up to now, long-term regional simulations of the Mediterranean Sea do not integrate the full sea level information from the Atlantic, which is a substantial shortcoming when analysing Mediterranean sea level response. In the present study we analyse different approaches followed by state-of-the-art regional climate models to simulate Mediterranean sea level variability. Additionally we present a new simulation which incorporates improved information of Atlantic sea level forcing at the lateral boundary. We evaluate the skills of the different simulations in the frame of long-term hindcast simulations spanning from 1980 to 2012 analysing sea level variability from seasonal to multidecadal scales. Results from the new simulation show a substantial improvement in the modelled Mediterranean sea level signal. This confirms that Mediterranean mean sea level is strongly influenced by the Atlantic conditions, and thus suggests that the quality of the information in the lateral boundary conditions (LBCs) is crucial for the good modelling of Mediterranean sea level. We also found that the regional differences inside the basin, that are induced by circulation changes, are model-dependent and thus not affected by the LBCs. Finally, we argue that a correct configuration of LBCs in the Atlantic should be used for future Mediterranean simulations, which cover hindcast period, but also for scenarios
