The aim of this study was to create and to validate two scales that ascertain coaches' planing and decision making styles. Two scales were applied -one for decision-making style and the other for planning styles- to 334 handball coaches: 289 men and 44 women. The exploratory factorial analyses and Cronbach's alpha coefficients demonstrated that both scales had several appropriate psychometric properties (α>.70). Planning and decision-making were found to be related, as were relationships among authoritarian, democratic and permissive decision-making profiles and rigid, flexible and improvisational planning profiles, respectively.

The purpose of this study was to develop a questionnaire to investigate volleyball coaches' orientations toward the coaching process. The study was preceded by four developmental stages in order to improve user understanding, validate the content, and refine the psychometric properties of the instrument. Participants for the reliability and validity study were 334 Spanish volleyball team coaches, 86.5% men and 13.2% women. The following 6 factors emerged from the exploratory factor analysis: team-work orientation, technological orientation, innovative orientation, dialogue orientation, directive orientation, and social climate orientation. Statistical results indicated that the instrument produced reliable and valid scores in all the obtained factors (α>.70), showing that this questionnaire is a useful tool to examine coaches' orientations towards coaching.

Demography of the snail Plicopurpura pansa (Neotaenioglossa: Muricidae) and constitution of the associated mollusk community, in Guerrero, Mexico. We quarterly sampled the molluskan community of Playa Ventura, Guerrero, Mexico. Sample size (20 m² in 1 m² units) was determined by the spatial distribution pattern of Plicopurpura pansa using a negative binomial distribution. The density of the P. pansa was 5.19 snails/m² and the sex ratio near 1:1. The average size was 20.10 mm (most females were 10.5 to 27.0 mm; most males 12.0 to 27.0 mm). Density was high and small sized dominated. Mean size varied with time. General mean weight was 1.79 g. Females weight varied more, maybe because of the reproductive cycle. Recruits were collected in five samplings. Most copulation activity was in March of 2001. The associated community includes 26 species of Gastropoda, five of Bivalvia and one of Polyplacophora, Brachidontes semilaevis being dominant. [ABSTRACT FROM AUTHOR]

Introduction: In order to increase the number of sea turtle hatchlings, it is necessary to improve conservation strategies, such as nest incubation in hatchery conditions that counteract the effects of extreme climatic conditions. Objective: To compare five reproductive success parameters (hatching success, eggs with no apparent embryonic development, dead hatchlings, embryonic mortality, and incubation period) of the sea turtle Lepidochelys olivacea. Methods: The incubation of nests was evaluated under two periods of nest relocation, P1 ~28.8 °C (August and September) and P2 ~27.1 °C (October and November), average ambient temperature, under hatchery condition, in 2018 in Guerrero, Mexico. Results: Significant differences were found in hatching success and embryonic mortality between nest relocation periods (P < 0.001). In P1, lower values of hatching success (77.0 % P1 vs 88.6 % P2) and higher values of embryonic mortality (13.7 % P1 vs 3.3 % P2) were observed compared to those of P2. It's important pointing that, in the present study, embryonic mortality occurred at a late stage of development, that is, in almost fully developed embryos. No differences were found between periods regarding the parameters eggs with no apparent embryonic development, dead hatchlings and incubation period. Conclusions: The differences between the environmental conditions during the first period of nest relocation compared to the second period, respectively, seem to affect the hatching success and embryonic mortality of L. olivacea. Therefore, it is important to take action on this issue during this incubation stage to try to improve the incubation of nests under hatchery conditions. [ABSTRACT FROM AUTHOR]

It is necessary to analyze the impact that the competition have on athletes, in an objective and scientific way. The knowledge of the physiological and kinematic demands in sports competition is one of the factor that will establish optimal training processes. Therefore, the main objectives of this research were to characterize and analyze the differences between training and real competition in a women's senior basketball team during 2015/16 season. The design of this research is empirical with quantitative methodology, which focuses on analyzing the relationships and differences between variables. The independent variable was the Game Situation, categorized in Small Sided Games, Full Game and Competition. Five dependent variables were recorded: Impacts, Steps and Jumps per minute (kinematic variables); and Average and Maximum Heart Rate (internal load). A descriptive analysis was performed and the univariate general linear model was used to differentiate between categories of the variable Game Situation. Finally, Bonferroni Post Hoc test was used to identify differences between groups. The results showed that higher values of Average and Maximum Heart Rate and Steps per minute were found in competition. Coaches should consider these results to adapt the training to the requirements of the competition. [ABSTRACT FROM AUTHOR]

The aim of this research was to determine the differences that may exist in the gender of the referee about the technical intervention and stressful situations during basketball matches. The subjects are six national referees (4 men and 2 women) officiating an international tournament U-16. IOVAB instrument has been used to calculate the differences in the technical intervention and LISEA questionnaire in order to observe differences in stress situations. The results show no significant differences in technical intervention, except the head referee movements, where the women performance is better. However, there are differences between groups in stressful situations. Women have higher values in reference to the name of the coaches and players, the position occupied by each team in the competition, the workmate referee, the place and stadium and the existence of field official. Results show the need to implement an intervention program to regulate the anxiety of the referees before and after the games. [ABSTRACT FROM AUTHOR]

The State of Guerrero, Mexico, has priority marine areas for conservation of its biodiversity, but information concerning diversity of mollusks is limited, so it is convenient to carry out species inventories, studies of populations and community ecology. This study was conducted in the intertidal rocky beach Tlacopanocha. The objectives were to determine richness, density and species diversity, analyze the species composition and size structure. The sampling area was 10 m² and the sampling unit was 1 m². 35 species were identified of which three are new records for the intertidal rocky shores of the State of Guerrero. The best represented families in species richness were Ischnochitonidae and Arcidae, and Chamidae, and Chitonidae in abundance; species density was 31.60 ind m-2. Polyplacophora showed 42.9% of dominant species and Bivalvia 19.0%. Chama corallina showed the greatest length and Chama sordida the greatest width. Species richness of mollusks recorded is considered high and in agreement with tropical rocky substrates. Polyplacophora showed high species composition, which could be the result of adaptation of organisms to the dynamic conditions of the rocky intertidal. New records indicate the importance of species inventories and knowledge of the populations and community's dynamics of the Guerrero marine fauna. [ABSTRACT FROM AUTHOR]
