[EN] First description of the complete embryo and larval development of the Canarian abalone (Haliotis tuberculata coccinea Reeve.) was conducted along 39 stages from fertilization to the appearance of the third tubule on the cephalic tentacles and illustrated in a microphotographic sequence. Eggs obtained by induced spawning with hydrogen peroxide from the GIA captive broodstock were stocked at a density of 10 eggs/mL and kept at 23 0.5 BC for 62 h until the formation of the third tubule. Live eggs and larvae were continuously observed on a 24 h basis at a 3400 magnification under transmitted light. At each stages, specific morphological features, illustrated by microscopic photographs, were described, as well as the time required for their apparition. Fertilized eggs diameter was 205 8 mm (mean SD), whereas length and width of larvae ready to undergo metamorphosis were 216.6 5.3 mmand 172 8.8 mm, respectively. Knowledge on the larval morphological development acquired through this study will contribute to the improvement of larval rearing techniques for this abalone species.

[EN]A range of factors may affect the composition and abundance of macroalgae on subtidal rocky reefs. We experimentally determined the interactive effect of the occurrence of the long-spine sea urchin, Diadema antillarum, depth and sedimentation levels on macroalgal assemblage structure on eastern Atlantic rocky reefs. Specifically, we manipulated sea urchin densities (removal of all individuals vs. untouched controls at natural densities) on rocky reefs devoid of erect vegetation, and predicted (1) that removal of sea urchins would differently affect macroalgal assemblage structure between deep (16-18 m) and shallow (8-9 m) reef strata, and that (2) the effect of sea urchin removal on macroalgae would be altered under different scenarios of sedimentation (ambient vs. enhanced). Experimental circular plots (2 m in diameter) were set up at 3 locations at Gran Canaria (Canarian Archipelago), and were maintained and monitored every 4 wk for 1 y. At the end of the experimental period, the structure of the algal assemblages differed between urchin treatments and depth strata, with a larger cover of turf and bushlike algae where urchins were removed and at the shallow reef stratum. More important, differences in algal assemblage structure between urchin treatments were irrespective of sedimentation levels, but shifted from the shallow to the deep stratum. This interactive effect was, in turn, observed for bushlike algae, as a result of a larger magnitude of response (i.e., larger cover) in the shallow stratum relative to the deep stratum, but was not detected for either turf or crustose coralline algae. These results highlight the importance of sorne physical conditions (here, differences in depth) to interact with biotic processes (here, urchin abundance) to create patterns in the organization of subtidal and benthic assemblages

L’obiettivo di questo studio è analizzare in che misura e con quali modalità le società di un mercato ricco ed importante come quello della National Basketball Association stiano sfruttando i canali messi a disposizione dal Web 2.0 e dai cosiddetti nuovi media. Il progetto si propone quindi di rispondere ai seguenti tre quesiti di ricerca:
 1 Quali sono gli strumenti attualmente a disposizione delle società NBA per promuovere il loro “prodotto” relativamente all’utilizzo delle tecnologie del Web 2.0 e dei Social Media?
 2 Quali vantaggi e quali cambiamenti hanno portato queste nuove tecnologie nella comunicazione e nelle relazioni tra impresa sportiva ed i suoi fan?
 3 E' possibile individuare un indice di esposizione su Web e Social Media applicato ai teams NBA in grado di fornire una stima di quanto e come una società stia usando questi mezzi? Il progetto inizia con un’analisi dello stato dell’arte, partendo dal settore più generale del marketing e del management dello sport, passando per l’utilizzo dei Social Media nel settore sportivo fino a focalizzarsi sugli studi specifici relativi al mondo NBA. Successivamente lo studio segue tre fasi: una prima introduttiva dove sono descritti i principali mezzi disponibili per le società in termini di Social Media Marketing e gli effetti benefici che questi possono avere; una seconda fase in cui viene definito l’indice nei suoi diversi parametri, ed infine un’ultima fase in cui vengono raccolti i dati relativi ad un campione di squadre NBA ed analizzati per elaborare i risultati ottenuti. L’elaborazione dei risultati porta poi ad individuare trend comuni, punti di forza e debolezza ed eventuali migliorie future per le strategie delle società NBA.

Tis the season of the National Basketball Association finals and the beginning of the Professional Women's Basketball Association. The skills of collaboration and teamwork required to achieve the ballet of basketball is learned by players over a number of years. On school grounds everywhere, children are learning the techniques and skills necessary to play the game of basketball. Recently, I saw a coach on the sidelines screaming at a young player to make her free-throws, and if she missed, she would have to run laps. This reminded me of traditional services to families which threaten, or at best demand a certain level of performance of parents without providing any true "coaching". I often watch our college coach work from a strengths perspective with the team on minute techniques such as the match-up defense and in-bounds plays. This is the approach that family preservation must employ with families, programs, and their communities.

Trata de la evaluación de la biblioteca universitaria brasileña en el marco de la legislación y de la normativa del gobierno. Considera, desde un punto de vista teórico, las cuatro generaciones que establecieron las pautas de la evaluación en los últimos cien años, siendo que la última se refiere a los parámetros de modo negociado e interactivo con los partícipes del proceso. Presenta el Sistema Nacional de Evaluación de la Educación Superior (SINAES) creado en 2004, sus características y funciones, además de las modalidades e instrumentos evaluativos. En él, se pone de relieve la Evaluación de los Cursos de Grado (carreras), teniendo en cuenta que es donde se ve la posición de la biblioteca universitaria y las condiciones en que se la evalúa. Asimismo, se incluyen las actuales iniciativas que ocurren en el país, unas divergentes otras convergentes, siendoque las últimas son las que anuncian alguna posibilidad de establecerse (a) oficialmenteindicadores de rendimiento para las bibliotecas universitarias, por la labor de laAsociación Brasileña de Normas Técnicas (ABNT), y (b) la lucha por la creación de una red nacional de bibliotecas universitarias, a partir de un Forum de Dirigentes de Bibliotecas Universitarias en el ámbito de la Asociación Nacional de Dirigentes de las Instituciones Federales de Enseñanza Superior (ANDIFES), como una instancia de interlocución con el gobierno y de coordinación de las políticas y prácticas de planificación y gestión.

A inferência de estratégias ofensivas em esportes coletivos pode ser realizada a partir da análise dos padrões de jogo observados durante a disputa. Para que isso ocorra, há a necessidade da formalização de classes de comportamentos específicos para a modalidade de forma a discriminar perfis de jogo com base na identificação das ações mais recorrentes. No basquetebol as ações são encadeadas ao longo da posse de bola, sendo que os diferentes tipos de sequências de ações contêm características que os diferenciam e podem influenciar diretamente no desfecho do ataque. Nesse trabalho foi apresentada uma proposta contendo diferentes possibilidades de sequenciamento de dinâmicas ofensivas baseadas em um modelo teórico descrito na literatura. Os procedimentos de validação do sequenciamento de dinâmicas ofensivas e os testes de reprodutibilidade e objetividade realizados junto a técnicos de basquetebol apresentaram valores elevados demonstrando a consistência dos critérios para a elaboração de 27 tipos de concatenações dependentes (Qui-quadrado >0,78). Além disso, a estrutura desenvolvida foi concluída através da aplicação do constructo a jogos de basquetebol da liga profissional Americana (NBA) (28 partidas, dentre as quais 10 partidas do confronto entre Spurs x Thunder, 10 partidas referentes ao confronto entre Heat e Pacers e 8 partidas da disputa envolvendo Heat e Spurs, sendo analisados ambos os ataques em cada confronto, válidos pela temporada regular e na fase de playoffs). Os resultados gerados a partir da análise foram apresentados através de árvores de decisão e grafos de modo a facilitar a visualização dos comportamentos identificados. A árvore de decisão apresentou as ações na sequência exata em que ocorreram nas posses de bola, enquanto os grafos mostraram os encadeamentos mais recorrentes entre duas dinâmicas ofensivas. Assim ambas as técnicas se mostraram complementares e auxiliaram na observação e análise dos perfis de jogo de cada equipe e na realização de inferências acerca de sua estratégia ofensiva. A formalização dos tipos de sequenciamento de ações ofensivas pode auxiliar treinadores e profissionais do basquetebol no desenho de estratégias, análise dos padrões de suas equipes e adversários e estruturação de sessões de treinamento que considerem os comportamentos ofensivos de modo dinâmico e contextualizado dentro de um encadeamento lógico de ações de jogo

This article reviews the evolution of the concept of culture industries, when neither industry nor culture themselves are today what they were at the time when the term was coined. It attempts to explain the dilution of the term into more nebulous terms (“leisure industries,” “entertainment industries” or “creative industries”) and suggests new challenges for the research on culture industries. What is at stake is no longer an application of a Fordist production to culture, a one-directional mass communication and a mediation by experts, but rather: (1) a cultural experience which is no longer clearly separated from other activities (leisure in general, consumption and even work); (2) the communicative explosion of all industrial production in a media environment, where industrialized symbolic products are mixed with culturalized industrial products; and (3) the empowerment of the recipient, which on one hand ignores the traditional experts and on the other leads to post-productive (recreational and even creative) cultural practices.

In this study, we assessed whether contextual factors related to where or when an athlete is born influence their likelihood of playing professional sport. The birthplace and birth month of all American players in the National Hockey League, National Basketball Association, Major League Baseball, and Professional Golfer's Association, and all Canadian players in the National Hockey League were collected from official websites. Monte Carlo simulations were used to verify if the birthplace of these professional athletes deviated in any systematic way from the official census population distribution, and chi-square analyses were conducted to determine whether the players' birth months were evenly distributed throughout the year. Results showed a birthplace bias towards smaller cities, with professional athletes being over-represented in cities of less than 500,000 and under-represented in cities of 500,000 and over. A birth month/relative age effect (in the form of a distinct bias towards elite athletes being relatively older than their peers) was found for hockey and baseball but not for basketball and golf. Comparative analyses suggested that contextual factors associated with place of birth contribute more influentially to the achievement of an elite level of sport performance than does relative age and that these factors are essentially independent in their influences on expertise development.
