Tagging reveals limited exchange of immature loggerhead sea turtles (Caretta caretta) between regions in the western Mediterranean.

Exchange of immature loggerhead sea turtles (Caretta caretta) between the northern and southern regions of the western Mediterranean was investigated using data obtained from several Spanish tagging programmes. Tagged turtles ranged in straight carapace length from 23.0 to 74.0 cm. Thirty-six turtles were recaptured after an average interval of 390.5±462.6 days (SD). As the mean dispersal distance (MDD) of a turtle population that spreads over the western Mediterranean would stabilize after 117 days (CI 95%: 98 to 149), two analyses were conducted that included data from turtles recaptured after 98 and 149 days respectively. In both analyses, turtles were recaptured more often than expected in the same region where they had been tagged. No difference was found in either of the two regions between the average distance between the capture and recapture locations and the expected MDD if the turtles were to remain in the region where they were first captured. Turtles recaptured after 15 and 25 days respectively were excluded from the analysis to ensure data independence. The overall evidence indicates that immature turtles exhibit strong site fidelity to certain areas and that there is a strong barrier to dispersal between the northern and southern parts of the western Mediterranean. Therefore, loggerhead turtles in the western Mediterranean should be split into at least two management units.

Exchange rate predictability

The main goal of this article is to provide an answer to the question: "Does anything forecast exchange rates, and if so, which variables?". It is well known thatexchange rate fluctuations are very difficult to predict using economic models, andthat a random walk forecasts exchange rates better than any economic model (theMeese and Rogoff puzzle). However, the recent literature has identified a series of fundamentals/methodologies that claim to have resolved the puzzle. This article providesa critical review of the recent literature on exchange rate forecasting and illustratesthe new methodologies and fundamentals that have been recently proposed in an up-to-date, thorough empirical analysis. Overall, our analysis of the literature and thedata suggests that the answer to the question: "Are exchange rates predictable?" is,"It depends" -on the choice of predictor, forecast horizon, sample period, model, andforecast evaluation method. Predictability is most apparent when one or more of thefollowing hold: the predictors are Taylor rule or net foreign assets, the model is linear, and a small number of parameters are estimated. The toughest benchmark is therandom walk without drift.

Understanding the gains from wage flexibility: The exchange rate connection

We study the gains from increased wage flexibility and their dependence on exchange rate policy, using a small open economy model with staggered price andwage setting. Two results stand out: (i) the impact of wage adjustments on employment is smaller the more the central bank seeks to stabilize the exchange rate,and (ii) an increase in wage flexibility often reduces welfare, and more likely so ineconomies under an exchange rate peg or an exchange rate-focused monetary policy.Our findings call into question the common view that wage flexibility is particularlydesirable in a currency union.

Planificació i gestió esportiva en equips base de clubs de futbol amateur. Factors determinants en l'elecció d'un club de tipus lúdic o competitiu

L’etapa d’iniciació a l’esport té una importància majúscula en el procés d’aprenentatge dels jugadors, i per això també podem trobar dos tipus de clubs: els competitius, els quals estan influïts bàsicament pels resultats obtinguts; i els lúdics, on preval la diversió i el joc sobre l’especialització a l’esport. El que es pretén amb aquesta investigació és descobrir quins factors són més determinants per fer que les famílies escullin un tipus de club o un altre. Per tant, basant-nos amb el que diuen autors com Pacheco (2007), Wein (2004), Frattarola i Sans (2006) i Lasierra i Lavega (1993), s’han concretat una sèrie de factors determinants per l’elecció de cada tipus de club, així com d’altres que seran significatius per les famílies a l’hora de decantar-se per un o per l’altre. Pel que fa a la part metodològica, dir que és una investigació descriptiva transversal. A més, s’ha utilitzat l’estratègia de l’enquesta amb l’instrument del qüestionari, el qual s’ha basat en una mostra formada per 60 pares i mares de nens i nenes d’iniciació en l’esport, i 20 pares i mares de nens d’escoleta, previ a la iniciació esportiva. Pel que fa als resultats obtinguts, aquests mostren que al club lúdic es compleixen els tres factors d’aquest àmbit, mentre que al club competitiu es compleixen els dos mateixos factors lúdics de l’altre club i només un factor competitiu. D’altra banda, cal tenir present la importància que tenen els factors contaminadors en els resultats obtinguts degut a la significativitat d’aquests.

Impacte de la Gimnàstica artística a Vic: la relació gimnasta-entrenadora dins del Club Gimnàstic Osona (CGO)

L’objectiu d’aquest estudi és comprovar si una millor relació entre gimnasta i entrenadora és un factor determinant per a poder obtenir més resultats en les competicions. S’estudien tres grups dividits per tres nivells diferents: Escolar (8 gimnastes), Promogym (11 gimnastes) i Tecnificació (28 gimnastes). A partir d’una adaptació feta dels qüestionaris Cart-Q de Jowett i Ntoumanis (2004) i l’ SF-PANAS de Thompson (2007) es realitzarà l’anàlisi de la relació gimnasta-entrenadora abans de dues competicions, on s’analitzaran els podis. Observant l’estudi, una baixada de mitjanes dels aspectes de les 3 C’s (proximitat, compromís i complementarietat) estava acompanyat d’una baixada de resultats i una pujada de les mitjanes de les 3 C’s estava relacionat amb l’obtenció de més podis. Per tant, a l’hora de valorar els resultats en competició la relació gimnasta-entrenadora és un factor important a tenir en compte.

Differences in aerobic fitness and lifestyle characteristics in preschoolers according to their weight status and sports club participation.

Objective: This study assesses differences in adiposity, aerobic fitness, and lifestyle characteristics in preschoolers according to their weight status and sports club (SC) participation. Method: As part of the Ballabeina study, 600 randomly selected preschoolers (mean age 5.1 ± 0.6 years; 50.2% girls) were analyzed. Body composition was measured by bioelectrical impedance, aerobic fitness by the 20-meter shuttle run test, and physical activity by accelerometers. Eating habits, media use, and SC participation were assessed by questionnaires. Results: Overweight children (Swiss national percentiles) and children not participating in SC had both lower aerobic fitness and higher % body fat compared to their respective counterparts (all p ≤ 0.028). In addition, children not participating in SC were less physically active, had more media use, and ate less healthy compared to children participating in SC (all p ≤ 0.023). Controlling for parental sociocultural determinants attenuated differences in % body fat, in physical activity, and in eating habits. Conclusion: Aerobic fitness differs both according to weight status and SC participation in preschoolers. Furthermore, in view of the many differences in lifestyle behaviors, SC participation at this age could represent a more discriminatory indicator of healthy lifestyle characteristics than weight status.

Association of sports club participation with fitness and fatness in children.

Decreased fitness and increased fatness are relevant factors for decreased cardiovascular and bone health in children. One way to increase physical activity and hence fitness and to reduce the risk for overweight might be sports club participation (SCP). PURPOSE: To investigate the association of SCP with fatness and fitness in children in general and in those with increased risk for overweight and/or low fitness. METHODS: A cross-sectional study was conducted in a random sample of 502 first- and fifth-grade primary school children. Fitness components were determined by 10 motor tests and body fatness by the sum of four skinfolds. SCP was defined as participation of at least once a week. RESULTS: Two thirds of all children were participating in a sports club. Girls' and boys' participation rate as well as those of overweight children and of children with overweight parents were comparable to their respective normal weight peers. In contrast, children from migrant families (odds ratio = 0.31; 95% confidence interval = 0.20-0.48) and from inactive parents (odds ratio = 0.16; 95% confidence interval = 0.05-0.45) participated significantly less (all P < 0.001). SCP was associated with endurance (0.53 > beta > 0.37, all P < 0.05) and partly with speed, strength, and coordination (0.41 > beta > 0.18, all P < 0.05). In overweight children and in children from overweight parents and migrant families, this association was not found. There was no association between SCP and fatness in any of the groups. CONCLUSIONS: SCP rates were high and were associated with higher levels of most fitness components in children. Participation rates were lower for children of migrant families and children from inactive parents. In addition, the association between SCP and fitness components was not found in overweight children and in children from overweight parents and migrant families.

A simple halide-to-anion exchange method for heteroaromatic salts and ionic liquids

A broad and simple method permitted halide ions in quaternary heteroaromatic and ammonium salts to be exchanged for a variety of anions using an anion exchange resin (A− form) in non-aqueous media. The anion loading of the AER (OH− form) was examined using two different anion sources, acids or ammonium salts, and changing the polarity of the solvents. The AER (A− form) method in organic solvents was then applied to several quaternary heteroaromatic salts and ILs, and the anion exchange proceeded in excellent to quantitative yields, concomitantly removing halide impurities. Relying on the hydrophobicity of the targeted ion pair for the counteranion swap, organic solvents with variable polarity were used, such as CH3OH, CH3CN and the dipolar nonhydroxylic solvent mixture CH3CN:CH2Cl2 (3:7) and the anion exchange was equally successful with both lipophilic cations and anions.

Oxygen consumption of Litopenaeus vannamei juveniles in heterotrophic medium with zero water exchange

This work aimed at determining the dissolved oxygen consumption rate of Litopenaeus vannamei juveniles maintained in a microbial biofloc raceway system at high density with no aeration. Three 4 L bottles were filled for each treatment, sealed hermetically, and placed in an enclosed greenhouse raceway system. Four shrimp (13.2±1.42 g) were assigned to two sets of the bottles, which underwent the following treatments: light conditions with no shrimp; dark conditions with no shrimp; light conditions with shrimp; and dark conditions with shrimp. Dissolved oxygen content was measured every 10 min for 30 min. A quadratic behavior was observed in dissolved oxygen concentration over time. Significant differences for oxigen consumption were observed only at 10 and 20 min between shrimp maintained in the dark and those under light conditions. At 10 min, a higher value was observed in shrimp maintained under light, and at 20 min, in the dark. Significant differences between 10 and 20 min and between 10 and 30 min were observed when oxygen consumption was analyzed over time in the presence of light. Under dark conditions there were significant differences only between 20 and 30 min. Lethal oxygen concentration (0.65 mg L-1) would be reached in less than one hour either under light or dark conditions with no aeration.
