Coaches’ cultural intelligence: How do coaches rate themselves and what are their cultural training needs?

Cultural intelligence is the capability of a person to adapt effectively to different cultures. This capability has been investigated in areas such as management, military, and education. However, there are no studies in sport referring to this capability. It is important to study cultural intelligence in sport because of the increased globalisation resulting from coaches’ and athletes’ migration across countries and clubs. This study aimed to develop the CQsport and examine its factorial structure and psychometric properties; and examine coaches’ cultural intelligence and their perceived cross-cultural training needs. Participants were 209 football coaches either with or without international experience. Participants completed an online survey consisting of CQsport and a cross-cultural training needs questionnaire. We used a Multi-Group analysis, within the SEM approach, to test group differences in the CQsport and performed a One-Way ANOVA for comparisons across groups concerning cross-cultural training needs. Coaches with international experience rated themselves with more cultural intelligence in the sports context than coaches with no international experience on the metacognitive, cognitive, motivational and behavioural dimensions. Coaches with international experience also self-rated fewer training needs than coaches without international experience. This study represents the first attempt to examine football coaches’ cultural intelligence and their cross-cultural training needs

On the hydrogen neutral outflowing disks of B[e] supergiants

(abridged) B[e] supergiants are known to possess geometrically thick dusty disks. Disk-forming wind models have, however, been found to be insufficient in reproducing the observed dust emission. This problem arises due to the severe assumption that, as for classical Be stars, the near-infrared excess emission originates in the disk. Modeling of the free-free and free-bound emission therefore results in an upper limit for the disk mass loss rate, hampering dust condensation in the disk. We propose a revised scenario for the non-spherical winds of B[e] supergiants: a normal B-type line-driven polar wind and an outflowing disk-forming wind that is neutral in hydrogen at, or very close to the stellar surface. We concentrate on the pole-on seen LMC B[e] supergiant R126 and calculate the line luminosities of the optical [OI] emission lines with an outflowing disk scenario. In addition, we compute the free-free and free-bound emission from a line-driven polar wind and model the spectral energy distribution in the optical and near-infrared. Good fits to the [OI] line luminosities are achieved for an outflowing disk that is neutral in hydrogen right from the stellar surface. Neutral thereby means that hydrogen is ionized by less than 0.1%. Consequently, the free-free and free-bound emission cannot (dominantly) arise from the disk and cannot limit the disk mass loss rate. The hydrogen neutral outflowing disk scenario therefore provides an ideal environment for efficient dust formation. The spectral energy distribution in the optical and near-infrared range can be well fitted with the stellar continuum plus free-free and free-bound emission from the polar line-driven wind. Our modeling further delivers minimum values for \dot{M}(disk) > 2.5d-5 M_sun/yr and for the density contrast between equatorial and polar wind of ~10.Comment: 9 pages, 8 figures, accepted for publication in A&

Interferência da microbiota autóctone do queijo coalho sobre Staphylococcus coagulase positiva.

Níveis elevados de contaminantes microbiológicos, comumente encontrados em alimentos de origem animal e ambientes de processamento de alimentos, são aptos de impedir o crescimento de patógenos nestes produtos. Em alguns contextos onde bactérias ácido láticas (BAL) constituem a microbiota dominante, como nos produtos lácteos, Staphylococcus coagulase positiva (SCP) colonizam, persistem e produzem intoxicação alimentar. Com o objetivo de verificar a possível interferência da microbiota encontrada no queijo Coalho sobre a presença de SCP, 64 amostras provenientes de 16 laticínios foram submetidas a análises microbiológicas para determinar os níveis de microrganismos aeróbios mesófilos (MAM), BAL e SCP. Os resultados obtidos mostraram que a microbiota autóctone das amostras analisadas não gerou condições inadequadas ao crescimento, desenvolvimento e isolamento de SCP, uma vez que este patógeno foi detectado mesmo nas amostras que apresentaram altos níveis de contagens de MAM e BAL

Effects of supplementation of L-carnitine on the body composition of trained and sedentary rats

El objetivo del presente estudio es determinar el efecto de la suplementación de L-carnitina sobre la composición corporal de ratas entrenadas y sedentarias. Fueron seleccionadas de forma aleatoria 30 ratas machos Wistar, de 12 semanas de vida, cuyo peso osciló entre 350 a 380 gramos, constituyéndose cuatro grupos de animales: sedentario no suplementado (SNS), sedentario suplementado (SS), entrenado no suplementado (ENS) y entrenado suplementado (ES). El entrenamiento fue realizado con sesiones de carrera en la estera rodante, con duración de una hora y con suplementación oral crónica de L-Carnitina. Ambos protocolos con una duración de 4 semanas. La composición corporal fue evaluada a través de ecuaciones de predicción para determinar la masa libre de grasa (MLG) y masa de grasa (MG). Los resultados muestran que el entrenamiento físico disminuye los valores de la MLG y MG en el grupo ENS, y que la administración de la L-carnitina en forma conjunta con el entrenamiento físico revierte parcialmente la reducción de la MLG en el grupo ES. Finalmente se concluye que el ejercicio físico debe ser realizado juntamente con la suplementación de L-carnitina, permitiendo una disminución de la MG y mantener los niveles de MLG en ratas en proceso de crecimiento.The aim of this study is to determine the effect of L-carnitine supplementation on body composition of trained and sedentary rats. Were randomly selected 30 male Wistar rats of 12 weeks of age, whose weight ranged between 350 to 380 grams, four groups of animals: sedentary non-supplemented (SNS), sedentary supplemented (SS), trained not supplemented (ENS) trained and supplemented (ES). The training was done with sessions running on a treadmill, lasting an hour and chronic oral supplementation of L-carnitine. Both protocols with a duration of 4 weeks. Body composition was assessed by prediction equations to determine fat-free (FFM) and fat mass (FM). The results show that physical training decreases the values of FFM and FM in the ENS group, and that the administration of L-carnitine together with physical training partially reverses the reduction of MLG in ES. Finally concluded that physical exercise should be conducted jointly with the supplementation of L-carnitine, allowing a reduction in the MG and maintain levels in rats MLG growth process.Peer Reviewe

Modeling electrodialysis and a photochemical process for their integration in saline wastewater treatment.

Oxidation processes can be used to treat industrial wastewater containing non-biodegradable organic compounds. However, the presence of dissolved salts may inhibit or retard the treatment process. In this study, wastewater desalination by electrodialysis (ED) associated with an advanced oxidation process (photo-Fenton) was applied to an aqueous NaCl solution containing phenol. The influence of process variables on the demineralization factor was investigated for ED in pilot scale and a correlation was obtained between the phenol, salt and water fluxes with the driving force. The oxidation process was investigated in a laboratory batch reactor and a model based on artificial neural networks was developed by fitting the experimental data describing the reaction rate as a function of the input variables. With the experimental parameters of both processes, a dynamic model was developed for ED and a continuous model, using a plug flow reactor approach, for the oxidation process. Finally, the hybrid model simulation could validate different scenarios of the integrated system and can be used for process optimization
