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

The effect of polyethyllene gyicol (Peg) on protein output of free range Alentejano pigs

The effect of PEG treated or untreated acorns fed to Alentejano pigs, on the protein output of the animals were studied. The animals had access to two sown pasture fields based on Trifolium incarnatum and Lolium westerwoldicum. Four dietary treatments were tested with 5 pigs per treatment in a two by two factorial experimental design (factor 1: sown species; factor 2: acorn with or without PEG). Intake of acorns and protein faecal concentration were measured individually. Faecal output was estimated using an external faecal marker (dotriacontane, C32). Crude protein faecal concentration of animals fed acorns treated with PEG was significantly lower (P<0,05) then those fed untreated acorns, suggesting that the PEG may have increased the availability of dietary protein to the animals. However, the estimation of protein faecal output using the n-alkane C32 was not significantly affected by the PEG treatment, even though, for the animals in the Lolium westerwoldicum pasture, there was a decrease (P=0,063) in the total excretion of CP when acorns were treated with PEG

Copper and lead removal by peanut hulls: equilibrium and kinetic studies

This research work aims to study the use of peanut hulls, an agricultural and food industry waste, for copper and lead removal through equilibrium and kinetic parameters evaluation. Equilibrium batch studies were performed in a batch adsorber. The influence of initial pH was evaluated (3–5) and it was selected between 4.0 and 4.5. The maximum sorption capacities obtained for the Langmuir model were 0.21 ± 0.03 and 0.18 ± 0.02 mmol/g, respectively for copper and lead. In bi-component systems, competitive sorption of copper and lead was verified, the total amount adsorbed being around 0.21 mmol of metal per gram of material in both mono and bi-component systems. In the kinetic studies equilibrium was reached after 200 min contact time using a 400 rpm stirring rate, achieving 78% and 58% removal, in mono-component system, for copper and lead respectively. Their removal follows a pseudo-second-order kinetics. These studies show that most of the metals removal occurred in the first 20 min of contact, which shows a good uptake rate in all systems

Copper, nickel and zinc removal by peanut hulls: batch and column studies in mono, tri-component systems and with real effluent

The main goal of this research study was the removal of Cu(II), Ni(II) and Zn(II) from aqueous solutions using peanut hulls. This work was mainly focused on the following aspects: chemical characterization of the biosorbent, kinetic studies, study of the pH influence in mono-component systems, equilibrium isotherms and column studies, both in mono and tri-component systems, and with a real industrial effluent from the electroplating industry. The chemical characterization of peanut hulls showed a high cellulose (44.8%) and lignin (36.1%) content, which favours biosorption of metal cations. The kinetic studies performed indicate that most of the sorption occurs in the first 30 min for all systems. In general, a pseudo-second order kinetics was followed, both in mono and tri-component systems. The equilibrium isotherms were better described by Freundlich model in all systems. Peanut hulls showed higher affinity for copper than for nickel and zinc when they are both present. The pH value between 5 and 6 was the most favourable for all systems. The sorbent capacity in column was 0.028 and 0.025 mmol g-1 for copper, respectively in mono and tri-component systems. A decrease of capacity for copper (50%) was observed when dealing with the real effluent. The Yoon-Nelson, Thomas and Yan’s models were fitted to the experimental data, being the latter the best fit
