Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / O presente trabalho analisou o conteúdo estomacal de cinco espécies de elasmobrânquios, sendo 9 estômagos de Psammobatis rutrum, 83 de Psammobatis extenta, 59 de Atlantoraja cyclophora, 112 de Rioraja agassizi e 43 de Rhizoprionodon lalandii, com o objetivo de obter informações sobre os hábitos alimentares dessas espécies, além de verificar a formação de guildas tróficas entre as espécies estudadas. As coletas ocorreram entre janeiro de 2006 e agosto de 2007, no litoral sul do Rio de Janeiro, ao largo da Ilha Grande. Os itens alimentares encontrados foram analisados quanto a Frequência de Ocorrência, Peso Percentual e Índice Alimentar, sendo a dieta de cada espécie avaliada considerando toda amostra, de acordo com o sexo dos indivíduos, estádios de maturidade e épocas do ano. Para investigar a similaridade entre as dietas e verificar a formação de guildas tróficas foi realizada uma Análise de Escalonamento Multidimensional (MDS). As dietas de Psammobatis rutrum e Psammobatis extenta foram consideradas carcino-bentófagas, com grande importância de camarões. O principal item para Atlantoraja cyclophora foi o siri Portunus spinicarpus, sendo a dieta considerada principalmente carcino-bentófaga, mas também com grande importância de teleósteos. Em Rioraja agassizi, a dieta foi considerada principalmente carcino-bentófaga, mas também com forte influência ictiófaga. Já o comportamento alimentar de Rhizoprionodon lalandii foi considerado ictio-bentófago. A dieta entre os sexos apresentou uma alta sobreposição em P. extenta, A. cyclophora e R. lalandii, mas para R. agassizi essa sobreposição foi considerada baixa. Entre os estádios de maturidade a sobreposição foi pequena para P. extenta e R. agassizi, entretanto para A. cyclophora e R. lalandii essa sobreposição foi elevada. Os exemplares maiores, aparentemente apresentaram preferência a se alimentarem de peixes, enquanto que predadores de menor porte se restringem aos invertebrados, basicamente crustáceos. Para todas as espécies foram identificadas alterações sazonais na importância dos itens alimentares, que pode ser explicado pelas oscilações naturais na composição e abundancia das presas potenciais em consequência das variações das massas de água na plataforma continental do sul fluminense. Os resultados indicaram a formação de 2 guildas, sendo a guilda 1 composta por P. rutrum e P extenta e com uma dieta principalmente de crustáceos (camarões) e a guilda 2 composta por A. cyclophora, R. agassizi e R. lalandii apresentando uma alimentação em Crustáceos e em Teleósteos. / This study examined the stomach contents of 9 specimens of Psammobatis rutrum, 83 of Psammobatis extenta, 59 of Atlantoraja cyclophora, 112 of Rioraja agassizi and 43 of Rhizoprionodon lalandii, in order to provide information about the diet of these species, besides verifying the formation of trophic guilds between the species studied. Sampling was carried out off the southern coast of Rio de Janeiro, from January 2006 to August 2007. The food items were analyzed by Frequency of Occurrence, Percentage Weight and Alimentary Index. The diet of each species was evaluated considering the whole sample, according to the sex of the individuals, stages of maturity and seasons. An analysis of Multidimensional Scaling (MDS) was performed to investigate the similarity between diets and to verify the formation of trophic guilds among the studied species. Psammobatis rutrum and Psammobatis extenta were considered benthic crustacean feeders. Atlantoraja cyclophora feed mainly in the crab Portunus spinicarpus, but teleosts were also important. The diet of Rioraja agassizi were mainly in crustacean and teleosts and Rhizoprionodon lalandii was considered a benthic teleost feeder. The diet between sexes showed a high overlap for P. extenta, A. cyclophora and R. lalandii, but for R. agassizi this overlap was considered low. Between the maturity stages overlap was low for P. extenta and R. agassizi, however for A. cyclophora and R. lalandii it was high. Apparently, larger specimens showed a preference to feed on fish and smaller predators restricted to invertebrates, mainly crustaceans. For all species were identified seasonal changes in the importance of food items and this can be consequence by natural fluctuations in the composition and abundance of potential prey as a result of variations of water masses on the continental shelf. The results showed that 2 guilds were formed. The guild 1 was composed by P. extenta and P. rutrum, with a diet mainly in crustacea, and the guild 2 was composed by A. cyclophora, R. agassizi and R.lalandii, that feeding on crustacea and teleosts

The monitoring fishes guild in the year 2009 was effected on territory, which manages drainage area upper Vltava, namely on it duvet-covers going to the head Lipno 1 on tributary river Vltava. Following was conducted by on in advance you - nap localities, having above all naturaly character plus - minimum share anthropogenic hits. To monitoring fishes guild choice flows was used postponement by the help of electric current. Hunt was organized in 100 m sections - progressed upstream flow in his entire latitude. Individual hunts sorts were to be generically determination by the help of specific portfolio was given their longitude bodies consequently were to be undamaged fish returned back to flow. On the grounds bring out was evaluation state fishes guild, near whose we're determine funds generic abundance, biodiversity, ekvitabilition, dominantion, size variability etc . Following proceeded on 8 localities (CHKO and NP Bohemia Forest). Most often recorded sorts were to be Salmo trutta m. fario, Phoxinus phoxinus, Gobio gobio, Thymallus thymallus plus snug plus endangered species Lampetra planeri, , Cottus gobio and Lota lota

Such sharing can result from different environmental performance and morphological changes resulting from the differential use of food resources. In this study, we evaluated the dynamic of partitioning of food resources in a guild of piscivorous fish, considering the ecomorphology and feeding of the species. Samples were collected monthly, between March/2007 and February/2008, the pond Curralinho, inserted in the semiaridnortheast. We evaluated the five most abundant species ofpiscivorous guild, and they are Acestrorhynchus lacustris, Acestrorhynchus britskii, Hoplias malabaricus, Pygocentrus piraya e Serrasalmus brandtii. The association of the informations trophics and ecomorphologicals of the evaluated piscivores resulted in similar patterns of clustering, demonstrating that the species that used different food resources, also possessed distinct morphological. The first group focused concentrated the two Serrasalminae species, while the second contained Hoplias malabaricus and two species of Acestrorhynchus. Among the species of Serrasalminae and Acestrorhynchus, morphological changes were not observed. However, among the members of Serrasalminae differences were observed in the strategies and food preferences, indicating a partitioning of resources between them. Such sharing can be evidenced by the intermediate value of dietary overlap between these two species. The food overlap index shows high values just within the group formed by H malabaricus and the two Acestrorhynchus species, however H. malabaricus differed in their strategy and food preference, which can contribute to reducing the potentialcompetitive with Acestrorhynchus. Just between the two species Acestrorhynchus did not show differences in strategy and food preference, indicating that theyhad the highest competitive potential between piscivorous evaluated. We emphasize the importance of the concomitant use of analysis ecomorphological and feeding, which is essential to a better understanding of the real trophic sharing. / A dinâmica da partilha de recursos, entre espécies de uma mesma guilda trófica, reduz a competição e possibilita a coexistência entre elas. Essa partilha pode decorrer do desempenho ecológico diferenciado resultante de variações morfológicas e da utilização diferenciada dos recursos alimentares. Neste estudo, avaliou-se a dinâmica da partilha de recursos alimentares numa guilda de peixes piscívoros, considerando a ecomorfologia e alimentação das espécies. As coletas foram realizadas mensalmente, entre março/2007 e fevereiro/2008, na lagoa Curralinho, inserida no semiárido nordestino. Foram avaliadas as cinco espécies mais abundantes da guilda dos piscívoros, sendo elas Acestrorhynchus lacustris, Acestrorhynchus britskii, Hoplias malabaricus, Pygocentrus piraya e Serrasalmus brandtii. A associação das informações ecomorfológicas e tróficas dos piscívoros avaliados resultou em padrões similares de agrupamento, demonstrando que as espécies que utilizaram recursos alimentares diferenciados, também possuíram padrões morfológicos distintos. O primeiro grupo concentrou as duas espécies de Serrasalminae, enquanto o segundo conteve Hoplias malabaricus e as duas espécies de Acestrorhynchus. Entre as espécies de Serrasalminae e Acestrorhynchus não foram observadas variações morfológicas. No entanto, entre os integrantes de Serrasalminae, foram observadas diferenças nas estratégias e preferências alimentares, indicando uma partilha dos recursos entre elas. Essa partilha pode ser evidenciada pelo valor intermediário de sobreposição alimentar entre estas duas espécies. O índice de sobreposição alimentar apresentou altos valores apenas dentro do grupo formado por H. malabaricus e as duas espécies de Acestrorhynchus,, entretanto H. malabaricus diferiu em sua estratégia e preferência alimentar, o que pode contribuir para a redução do potencial competitivo com Acestrorhynchus. Apenas entre as duas espécies de Acestrorhynchus não foram evidenciadas diferenças na estratégia e preferência alimentar, indicando que elas apresentaram o mais elevado potencial competitivo entre os piscívoros avaliados. Ressaltamos a importância da utilização concomitante de análises ecomorfológicas e de alimentação, que são indispensáveis para uma melhor compreensão da real partilha trófica.

The emerald ash borer (EAB, Agrilus planipennis Fairmaire) (Coleoptera: Buprestidae) is a non-native wood boring beetle that is causing extensive ash (Fraxinus spp.) mortality in eastern North America, affecting both urban and wildland forests and drastically altering forest structure and composition. As EAB-induced ash mortality progresses, native arthropod associates of ash forests are impacted by the effects of rapid and broad scale tree mortality. These include loss of food source, increased canopy gap formation, alterations in litter inputs causing shifting temperature and moisture regimes on the forest floor, and significant accumulation of coarse woody debris. I assessed the sub-canopy arthropod community in five forests, all in different stages of the invasion process, from introduction through impact. Additionally, I assessed the ground level arthropod community in a post EAB-invaded forest with 100% mature ash mortality. Arthropod communities were assessed at the ordinal level, and with a focus on coleopterans, they were further classified to families and trophic guilds to analyze abundance, richness, and diversity. Due to their overwhelming abundance, I identified scolytines collected in the post EAB-invaded forest to species to see if the EAB-invasion was part of a greater invasional meltdown. My results indicate that the EAB-invasion in North America is affecting the native coleopteran communities associated with these forests.

Cette recherche se propose d'étudier le rôle et l'évolution de l'union des cinéastes en urss puis dans la nouvelle russie pour comprendre ses effets sur la gestion du cinéma, ses modes d'intervention à différents moments clés de l'urss pour reconstituer à la fois l'aspect macro-social de cette union des cinéastes, son véritable rôle et fonctionnement et l'aspect micro-social, le parcours de ses membres au travers de l'évolution de certaines carrières à la fois emblématiques comme anonymes. Ces deux terrains d'études seront menés conjointement. il s'agira de comprendre comment l'union des cinéastes a contribué sur 50 ans (2 générations) à structurer tout un champ entre 1957 et 2009 ; quels ont été les modes d'adhésion comme d'exclusion; quels ont été les acteurs collectifs impliqués dans le processus ; quels ont été les principaux clivages ou coalitions à différents moments de cette histoire ; quels types de ressources ont été mobilisés au-delà même de ce que représente le cinéma et sa fonction en urss? Dans quelle mesure l'union des cinéastes a pu agir ou pas sur les transformations intervenues en russie sur cette période, au regard aussi du rôle qu'a pu jouer le cinéma dans la société soviétique et post-soviétique ? Comment mesurer à postériori l'impact réel de l'union dans l'organisation de la vie de ses membres au quotidien et comprendre comment ses différents acteurs ont été directement impliqués par cette organisation, s'y sont mobilisés ou même opposés à certains moments de l'histoire soviétique pour l'infléchir ? Nous nous demanderons enfin comment l'union des cinéastes peut être réévaluée à partir d'une recherche de terrain qui permettra de comprendre les ressorts de l'activité cinématographique en urss et en russie, le passage à la professionnalisation et sa légitimation par l'union, les processus de décomposition et recomposition organisationnels. / The Filmmakers Union was created in 1957 at the request of film professionals : by joining forces, they aimed atbringing the Party to recognize the collective aspect of their sphere of activity. This Union gradually gatheredall the professionals of the cinematographic sphere in addition to the sole filmmakers (critiques, teachers at theVGIK, technicians . . .). However it was quickly exploited by the Communist Party, who tried hard to controlfilmmakers more efficiently once they were grouped in a single structure. Thus, the Union members had tobalance their status of civil servant and that of representative of the artistic intelligentsia. The history of theFilmmakers Union, from its institutionalization until now can first be seen as a struggle to influence decisionson film production, and to obtain more freedom in the sphere of collective creation.Despite the internal conflicts stirred up by this ambiguous status, engaging the various actors involved in thesystem, within the framework of the Soviet and post-Soviet history, the Filmmakers Union survived on newfoundations inherited from the past. Its history enables us to understand the existence of a consensus beyondthe question of the work of art. The cinema agents, divided by the conflicts, are held together by their professionalismand by their vocation. The Union provides them with a strong identity within the Russian and Sovietsociety. Through some analysis of movies, emblematic of this period, and using our field research in Russia,the intention is to trace the history of this specific organization in order to put Soviet and Russian cinema intoperspective with a different approach.

The presented dissertation deals with the history of the painter's guild of the New Town of Prague with the main emphasis on its form and development in the 17th and 18th centuries but doesn't leave aside the period of older history. The work thus focuses on New Town painters from the beginnings of the existence of their guild, through the issuance of the privilege of Emperor Rudolf II. in 1595, by which he granted the Old Town-Lesser Town painter's guild significant privileges, as a result of which the joint development of all Prague painting associations began to take different paths. The thesis also deals with the circumstances leading to the demise of the guild in the 1780s, when the Prague painters' fraternities were abolished by Emperor Joseph II. In addition to the history of the painters' association, the thesis provides an insight into the guild life of New Town painters, which it monitors in individual positions within the guild hierarchy, focuses on the functioning of the association itself, its management, material and written sources, representation of the corporation and individual members, and last but not least, it describes the way of worshiping the patron saint of painters - St. Luke. Because not only members of the guild worked as painters in the New Town of Prague, the work also...

This thesis contributes to research that informs the studies of organizational management and organizational anthropology. It examines the internal hierarchy and organizational practices of a Tech Company and describes how findings contributed to policy recommendations aimed towards supporting a “guild” model for organizational success. The data collecting and research were undertaken while working as an employee of the Tech Program and subsequent analysis continued past the end of that phase of work. Methods included semi-structured interviews which captured the sentiments and understandings of employees within the organization, and a questionnaire which revealed sentiments and experiences from former employees. These were buttressed with participant observation engaged through a participatory action research methodology. Findings add to the work directed towards understanding the effect of Founder’s Syndrome within organizations. Additionally, this thesis contributes to a growing body of research centered on best practices for fostering positive organizational growth by creating lines of communication from front-line employees to management level employers.

This dissertation examines the dynamics of the oral communication which takes place in the Easter Vigil at St. Augustine's Anglican Church, Thaba 'Nchu. The study uses an analytical framework drawn from Orality Theory and Speech Act Theory, to analyse oral communication in the preaching and singing of the Vigil. Through an approach of Participant Observation, details were obtained of the Easter Vigils of 1994, 1995 and 1996. The historical and cultural background of this All-Night Vigil is traced in European Church History and African Traditional Religion. The roles of the Mothers' Union, the St. Agnes Guild and the Guild of Bernard Mizeki are also highlighted. / Missiology / M.Th (Missiology)
