RESUMO Esse estudo objetivou comparar indicadores temporais de acordo com o tipo de set e a diferença da pontuação final. Participaram do estudo 25 times masculinos de voleibol de praia (15 - 17 anos), que competiram nos Jogos Escolares Brasileiro, fase nacional. Foram observados 21 jogos, 42 sets e 1374 rallies. As variáveis analisadas foram a duração do rally, tempo de descanso entre os rallies, tempo total de trabalho, tempo total de descanso, duração do set, razão tempo de descanso : tempo de trabalho e quantidade de rallies. Comparou-se os indicadores de tempo entre o tipo de set (1ºset Vs. 2ºset) e categorias de equilíbrio de acordo com a diferença da pontuação final (desequilibrado, moderado equilíbrio e equilibrado), utilizando teste t e Anova de uma via, respectivamente. Não foi encontrada diferença significativa entre o 1º e 2º set, no entanto, efeito moderado foi observado no tempo total de trabalho. A diferença da pontuação final afetou a duração do set, o tempo total de trabalho e o trabalho total de descanso, mostrando uma tendência linear entre os níveis de equilíbrio. Os indicadores temporais parecem não se alterar em relação ao tipo de set, porém, há uma tendência de aumento do tempo de trabalho do 1º para o 2º set. Finalmente, a pontuação influencia a duração do set, tempo total de trabalho e tempo total de descanso, sem modificar a relação esforço : pausa.

ABSTRACT This study aimed to compare temporal indicators according to the type of set and final score difference. Twenty-five teams of male beach volleyball players (15 - 17 years old) competed in Brazilian School Championship, national stage. 21 matches, 42 sets, and 1374 rallies were observed. The variables analyzed were rally duration, rest time between rallies, total work time, total rest time, duration of the set, rest time : work time ratio, and the number of rallies. Time indicators were compared between the type of set (1st set Vs. 2nd set) and balance categories according to the difference in the final score (unbalanced, moderate balance, and balanced), using t-test and one-way ANOVA, respectively. No significant difference was found between the 1st and 2nd set, although a moderate effect was observed in total work time between sets. Moreover, the final score difference influences the duration of set, total work time, and total work-rest show a linear tendency between balanced levels. The temporal indicators do not seem to change concerning the type of set. However, there is a tendency for an increase in working time from the 1st to the 2nd set. Finally, the score influences the duration of the set, total work time, and total rest time, without modifying the effort : rest ratio.

RESUMO O estudo da forma de execução (técnica e aspectos espaciais) pode fornecer informações úteis para compreender a dinâmica do jogo no vôlei de praia e obter valores de referência para a análise do jogo e o estabelecimento de metas de treinamento. O objetivo do estudo foi determinar a influência da forma de execução no desempenho de saque e rali em jogadores de vôlei de praia de alto nível. Um total de 3.009 saques de 44 jogadoras de alto nível foram analisados. As variáveis estudadas foram: técnica de saque, zona de saque, destino do saque, desempenho de saque e desempenho de rali. Um desenho observacional pontual, nomotético, multidimensional e intragrupo foi utilizado. Foi realizada uma análise descritiva e inferencial dos dados (Teste Qui-Quadrado) utilizando o software SPSS v.21.0. O nível de significância foi estabelecido em p <0,05. A maneira de execução influencia o desempenho do saque. O saque flutuante de salto foi o mais usado. O destino mais efetivo foi a zona entre jogadoras, provavelmente devido ao deslocamento das jogadoras e a interferência entre elas. Não foi encontrada associação entre a técnica de saque e o desempenho de rally. Esses achados mostraram possíveis associações entre a maneira de executar o saque com as ações seguintes realizadas pelas jogadoras e as estratégias das jogadoras para controlar sua carga física. Esses valores podem ser úteis para orientar o treinamento de jogadoras ou avaliar jogadoras em competição de vôlei de praia.

ABSTRACT The study of the manner of execution (technique, and spatial aspects) can provide useful information to understand the game dynamics in beach volleyball and to obtain references values for the analysis of the game and the establishment of training goals. The aim of the study was to determine the influence of the manner of execution on serve and rally performance in elite women's beach volleyball players. A total of 3,009 serves from 44 women’s players were analyzed. The variables studied were: serve technique, serve zone, serve destination, serve performance, and rally performance. An observational punctual, nomothetic, multidimensional, and intragroup design was used. A descriptive and inferential analysis of the data (Chi-Square Test) was done using SPSS v.21.0 software. The level of significance was set at p < .05. The manner of execution influences the serve performance. The jump float serve was the most used. The most effective destination was the zone between players, probability due to the players' displacement and interference between them. An absence of association between serve technique and rally performance was found. These findings showed possible connections between the way of executing the serve with the following actions done by the players and the players' strategies to control their physical load. These values may be useful to guide to players training, or to evaluate players in competition.

ABSTRACT Purpose: To report our initial experience using a patient-specific 3D-printed renal tumor model for the surgical planning of a complex heminephrectomy in a horseshoe kidney. Materials and Methods: We selected a clinical case for a complex laparoscopic surgery consisting in a 53 year-old male presenting a local recurrence of a renal tumor in a horseshoe kidney with aberrant vascularisation previously treated with a laparoscopic partial nephrectomy. He is now proposed for a laparoscopic left heminephrectomy. Along with conventional imaging, a real-size 3D-printed renal model was used to plan de surgical approach. The perioperative experience of the surgical team was recorded. Results: The surgical team found the patient-specific 3D printed model useful for a better understanding of the anatomy and an easier surgical planning. Conclusion: The use of patient-specific 3D-printed renal models seem to be helpful for the surgical planning in complex renal tumors.

Abstract Socorro Island, in the Revillagigedo Archipelago, has the highest number of endemisms of any Mexican island. It provides habitat for 117 vascular plants, 26 % of which are endemic to the island. Also endemic to the island are one reptile and eight terrestrial bird species. However, the local ecosystem has been heavily degraded by exotic mammals over the past 140 years. The feral sheep (Ovis aries) has contributed to a 30% loss in habitat based on the island’s surface area. Another serious threat is the feral cat (Felis catus), which has severely impacted the island’s bird communities and the endemic Socorro tree lizard (Urosaurus auriculatus). Together, feral sheep and cats are responsible for the extinction in the wild of the Socorro dove (Zenaida graysoni) and the Socorro Elf Owl (Micrathene whitneyi graysoni), and pose a serious threat for other vulnerable species, such as the Townsend’s shearwater (Puffinus auricularis). The feral sheep was completely eradicated in 2012, which resulted in a rapid and remarkable recovery of the local vegetation cover. The eradication of the feral cat has been a complex issue to undertake due to the large size and topographical complexity of Socorro Island. In 2011 Grupo de Ecología y Conservacion de Islas, A. C. (GECI) started a feral cat control program, which scaled up into an eradication campaign. Here we report on the progress of the eradication campaign between 2011 and 2015, and provide a first assessment of the recovery of the native fauna. Beginning in 2011, camera traps were used to estimate cat abundance. Leg-hold and lethal traps were used to capture feral cats, some of them mounted with telemetry devices that alerted when traps were activated. Native vertebrates were monitored to confirm the positive effects derived from cat control efforts. By July 2015, 413 cats were dispatched using soft leg-hold and lethal traps, with a combined effort of 22,706 trap-nights. To date (mid-2016), cat abundance has decreased significantly, with cats being completely absent for several years in different areas of the island. The abundance of the endemic Socorro Island tree lizard and terrestrial birds has increased thanks to significant progress. Completing this important conservation action requires an increase in trapping efforts and the use of detection dogs, combined with night hunting. We estimate that the eradication of the feral cat will be completed by early 2017, after which the absence confirmation phase will begin.

Resumen Isla Socorro, Archipiélago de Revillagigedo, es la isla con el mayor nivel de endemismos en México. Es hábitat de 117 especies de plantas vasculares, 26 % de las cuales son endémicas. Alberga una especie de reptil y ocho especies de aves terrestres endémicas. Sin embargo, este ecosistema insular ha sido fuertemente degradado debido a la presencia de mamíferos exóticos por más de 140 años. El borrego feral (Ovis aries) causó la destrucción del hábitat en 30 % de la superficie de la isla. Otra seria amenaza es la presencia del gato feral (Felis catus), el cual ha tenido un severo impacto negativo por depredación sobre la avifauna nativa y la lagartija azul (Urosaurus auriculatus), endémica de Isla Socorro. Juntos, el gato y el borrego feral, son responsables de la extinción en el medio silvestre de la paloma de Socorro (Zenaida graysoni) y del tecolote de Socorro (Micrathene whitneyi graysoni), además de ser una seria amenaza para otras especies vulnerables, destacando la pardela de Revillagigedo (Puffinus auricularis). La erradicación del borrego feral se completó en 2012, lo que resultó en una rápida y notable recuperación de la cobertura vegetal. La erradicación del gato feral ha sido un reto mayor dado al gran tamaño y la complejidad topográfica de Isla Socorro. En 2011, el Grupo de Ecología y Conservación de Islas, A. C. (GECI) inició un programa de control de gato feral que poco tiempo después se convirtió en una campaña de erradicación. En este trabajo reportamos los avances de la erradicación entre los años 2011 y 2015, y ofrecemos una primera evaluación de la recuperación de la fauna nativa. Mediante el uso de cámaras trampa (a partir de 2011) se estimó la abundancia del gato feral. Para la captura de los gatos se emplearon trampas de cepo y letales, algunas equipadas con equipos de telemetría que alertan cuando éstas han sido activadas. Se realizaron monitoreos de vertebrados nativos a fin de confirmar los efectos positivos de los esfuerzos de control del gato feral. Hasta julio de 2015 se sacrificaron 413 gatos con trampas de cepo de cojinete y letales, con un esfuerzo acumulado de 22,706 trampas-noche. A la fecha (mediados de 2016), la abundancia de gatos ha disminuido aún más, y ya están completamente ausentes de varias zonas de la isla. La abundancia de la lagartija azul de Isla Socorro y las aves terrestres endémicas ha incrementado gracias a los avances en la erradicación del gato. A la fecha se ha logrado un avance significativo en la erradicación del gato feral. Para completar esta acción prioritaria de conservación, es necesario incrementar el esfuerzo de trampeo, así como el uso de perros de muestra combinado con cacería nocturna. Estimamos que la erradicación de gato feral se completará a principios de 2017, cuando iniciará la fase de confirmación de ausencia.

Abstract: Socorro is an oceanic island rich in biodiversity and endemisms. However, the island has been threatened by feral cats since 1957. The diet of this predator, determined through the analysis of stomach contents of 79 cats, consisted mostly of house mice (Mus musculus, 22.16%), endemic lizards (Urosaurus auriculatus, 15.09%), anthropogenic rubbish (15.09%), and insects (Orthoptera, 13.20%). The home range of the feral cat was identified through telemetry using four individuals with GPS/VHF radio-collars. The three males had a much larger average home range of 219.10 ha, as compared with 118.86 ha of the female. Knowing the home range of the Socorro Island feral cat is critical for the successful eradication of the island's invasive population. Thanks to this information, it is possible to calculate the trapping effort and the amount of bait needed per unit area to successfully carry out the ongoing eradication, contributing to the conservation of global biodiversity.

Resumen: Isla Socorro es una isla oceánica rica en biodiversidad y endemismos. Sin embargo, la isla ha sido impactada por el gato asilvestrado desde 1957. A través del análisis del contenido estomacal de 79 gatos se determinó la dieta de este depredador, la cual está constituida mayormente por el ratón doméstico (Mus musculus, 22.16%), la lagartija endémica (Urosaurus auriculatus, 15.09%), residuos antropogénicos (15.09%), e insectos (Orthoptera, 13.20%). Se identificó el ámbito hogareño de los gatos a través de telemetría, utilizando cuatro individuos con radio-collares GPS/VHF. El ámbito hogareño de los machos resultó de 219.10 ha en promedio, mucho mayor que el de las hembras que fue de 118.86 ha. Conocer el ámbito hogareño del gato asilvestrado de Isla Socorro es clave para la erradicación exitosa de la población de la isla. Gracias a esta información se ha podido calcular el esfuerzo de trampeo o la cantidad de carnada que deben ser empleadas por unidad de área durante la erradicación en curso, que es relevante para la conservación de la biodiversidad global.

Abstract The aim of this study was to analyse the technical-tactical performance profile of blocking and court defence actions for various age groups and categories of competition in men's volleyball. The sample comprised 16,454 blocks and 8,321 digs performed in 299 sets in several categories of competition (from U-14 to Olympic Games). A descriptive and correlational inter- and intra-group observational design was used. The variables studied were: category of competition, opponent's spike tempo, and block and dig performance. The results showed a significant increase in the percentage of blocks and digs derived from fast attacks and a significant improvement in performance of these actions to counteract slow attacks. Thus, improving in blocking and digging performance was observed at higher categories when the attack is performed slowly. This paper discusses various reasons for the evolution in defensive performance and the effects on the training process for various categories of competition in volleyball.

RESUMO A transparência das informações no âmbito de Responsabilidade Social Empresarial (RSE) é um elemento comum nos diferentes padrões. Nos últimos anos, houve uma proliferação de normas e modelos para formalizar estratégias de RSE. O objetivo desta pesquisa é avaliar o grau de implementação dos diferentes padrões de normatização das instituições financeiras espanholas. A análise foi realizada com os dados do ano de 2008, coincidindo com os primeiros sinais da crise econômica, servindo como um ponto de referência para analisar o efeito da crise. O trabalho de campo foi realizado por meio de uma pesquisa respondida por 57 instituições de crédito espanholas. Deparamo-nos com uma má aplicação das normas, que incluem a Iniciativa Global sobre a Elaboração de Relatórios (Global Reporting Initiative, GRI) e ISO 14001. Dada a orientação de mercado das instituições de crédito, os bancos incorporam padrões de qualidade muito mais elaborados e completos que outras instituições de crédito, como a implementação da norma AS 1000, que é equivalente à implementação conjunta da ISO 14000 e 9000.

ABSTRACT Transparency of information in the field of CSR (Corporate Social Responsibility) is common to various standards. In recent years there has been a proliferation of standards and models for the formalization of CSR strategies. The objective is to assess the degree of implementation of standards of normalization. The analysis was conducted with data from the year 2008, coinciding with the first signs of the financial crisis, serving as a reference point to analyze the effect of the crisis. The field work was conducted using a survey answered by 57 Spanish credit institutions. We found a low degree of implementation of standards. The GRI (Global Reporting Initiative) and the ISO 14001 stood out. In view of the orientation of credit institutions towards the market, Banks have incorporated much more elaborated and comprehensive quality standards than other credit institutions, such as the implementation of the standard AS 1000 that is equivalent to the joint implementation of the ISO 14000 and 9000.

RESUMEN La transparencia informativa en materia de Responsabilidad Social de la Empresa (RSE), es un elemento común en los distintos estándares. En los últimos años ha surgido una proliferación de estándares y modelos para la formalización de estrategias de RSE. El objetivo de esta investigación es valorar el grado de implantación de los diferentes estándares de normalización en las entidades financieras españolas. El análisis ha sido realizado con datos pertenecientes al año 2008, coincidiendo con los primeros síntomas de la crisis financiera, sirviendo como punto de referencia para analizar el efecto de la crisis. El trabajo de campo se realizó a través de una encuesta contestada por 57 entidades de crédito españolas. Nos encontramos con un escaso grado de aplicación de estándares. Destacan la Iniciativa de Reporte Global (Global Reporting Initiative, GRI) y la ISO 14001. Dada la orientación al mercado de las entidades de crédito, los bancos incorporan estándares de calidad mucho más elaborados y completos que las otras entidades de crédito ya que, por ejemplo, la implementación del estándar AS 1000 equivale a la implementación conjunta de las ISO 14000 y 9000.
