The Approach Behavior to Angry Words in Athletes : A Pilot Study

2019

An increasing number of studies have found that athletes have a higher level of aggression than non-athletes. Anger is an important factor in the generation of aggressive behavior, and anger has been found to relate to both approach behavior and avoidance behavior. The present pilot study compared the aggression level of athletes and non-athletes using the Buss-Perry Aggression Questionnaire, and examined the responses of participants to anger-related stimuli using the manikin task, a paradigm that measures approach-avoidance behavior. In total, 15 athletes and 15 non-athletes finished the questionnaire and the manikin task, which included two conditions. In the anger approach condition, pa…

Analistas simbólicos, jerarquía urbana y atracción de talento en las ciudades mundiales españolas (2005-2019): un análisis a partir de la EPA

2021

Este trabajo utiliza los microdatos de la Encuesta de población activa del INE entre 2005 y 2019 para analizar el nivel de competencias de la población ocupada, los procesos de cualificación del mercado de trabajo de las ciudades mundiales españolas (Madrid, Barcelona, Valencia, Sevilla y Bilbao) y el papel que están teniendo las migraciones de profesionales y técnicos altamente cualificados como reflejo de su capacidad diferencial para atraer talento externo. Siguiendo el marco conceptual propuesto por Allen J. Scott de creciente polarización de los mercados de trabajo metropolitanos entre una clase de «analistas simbólicos» de alta cualificación y una «subclase de servicios», se considera…

An impaired alveolar-capillary barrier in vitro : effect of proinflammatory cytokines and consequences on nanocarrier interaction.

2009

The alveolar region of the lung is an important target for drug and gene delivery approaches. Treatment with drugs is often necessary under pathophysiological conditions, in which there is acute inflammation of the target organ. Therefore, in vitro models of the alveolar-capillary barrier, which mimic inflammatory conditions in the alveolar region, would be useful to analyse and predict effects of novel drugs on healthy or inflamed tissues. The epithelial cell line H441 was cultivated with primary isolated human pulmonary microvascular endothelial cells (HPMECs) or the endothelial cell line ISO-HAS-1 on opposite sides of a permeable filter support under physiological and inflammatory condi…

Traits and phylogenies modulate the environmental responses of wood-inhabiting fungal communities across spatial scales

2022

Identifying the spatial scales at which community assembly processes operate is fundamental for gaining a mechanistic understanding of the drivers shaping ecological communities. In this study, we examined whether and how traits and phylogenetic relationships structure fungal community assembly across spatial scales. We applied joint species distribution modelling to a European-scale dataset on 215 wood-inhabiting fungal species, which includes data on traits, phylogeny and environmental variables measured at the local (log-level) and regional (site-level) scales. At the local scale, wood-inhabiting fungal communities were mostly structured by deadwood decay stage, and the trait and phyloge…

Assessment of the mobility of selected elements in bioleached mining waste from Zloty Stok (Poland)

2017

Different bioleaching processes were applied to mining wastes deposited in the highly polluted post-industrial region - Lower Silesia in Poland. The chemical characterization of the wastes before and after bioleaching processes was performed. The characterisation was based on the distribution of selected elements (Fe, Mn, As, Co, Cr, Cu and Ni) between operationally-defined phases. The phases were defined using a six-step extraction procedure optimised according to the properties of the studied mining wastes. The fractionation and total content of elements in wastes before and after various bioleaching treatments were studied using ICP MS (Inductively Coupled Plasma Mass Spectrometry)and FA…

Gulf of Maine shells reveal changes in seawater temperature seasonality during the Medieval Climate Anomaly and the Little Ice Age

2011

article i nfo In this study, we use subannually resolved oxygen isotope values of fossil (dead-collected) and modern (live- caught) bivalve shells (Arctica islandica L.) from the northwestern Atlantic (Gulf of Maine, USA) to reconstruct past seasonal changes in seawater temperature. Our results indicate decreased seasonal temperature amplitude of about 1.6 °C (or ∼21%) during Medieval times (ca. AD 1033-1062) compared to shells from the early Little Ice Age (ca. AD 1321-1391) and during the late 19th century (AD 1864-1886). Additionally, seasonal oxygen isotope data suggest that summers were cooler and winters were warmer in the Gulf of Maine during the 11th century compared to summers and …

The community of Cystoseira brachycarpa J. Agardh emend. Giaccone (Fucales, Phaeophyceae) in a shallow hydrothermal vent area of the Aeolian Islands …

2014

A Cystoseira brachycarpa community from a vent area off Panarea Island (Italy) was investigated in two sites at different pH values. At low pH, species richness and coverage were low and the community displayed a reduced reproductive capacity. Conversely, at normal pH, dense canopies of fertile C. brachycarpa were found.

Comparative sclerochronology of modern and mid-Pliocene (c. 3.5Ma) Aequipecten opercularis (Mollusca, Bivalvia): an insight into past and future clim…

2009

Records of environment contained within the accretionarily deposited tissues of fossil organisms afford a means of detailed reconstruction of past climates and hence of rigorous testing of numerical climate models. We identify the environmental factors controlling oxygen and carbon stable-isotopic composition, and microgrowth-increment size, in the shell of modern examples of the Queen Scallop, Aequipecten opercularis. This understanding is then applied in interpretation of data from mid-Pliocene A. opercularis from eastern England. On the basis of oxygen-isotope evidence we conclude that winter minimum seafloor temperature was similar to present values (typically 6–7 °C) in the adjacent so…
