African Clarias taxonomy: Implications for the field worker

The taxonomy of African Clarias was reviewed. It was emphasized that much confusion still exists in this taxonomy. The major sources of this confusion were outlined. There are now only about 33 valid species of the 122 original species so far described in Africa. The implications of the present state of African Clarias taxonomy for the field worker were highlighted. In particular the need for the field worker to be an informed amateur taxonomist in addition to the possession of a good knowledge of the biology of his fish was emphasized. The connection between this and a successful Clarias culture was pointed out

Waterfowl and their role in lake ecosystems. [Translation from: Wiadomosci Ekologiczne 19, 355-371, 1973.]

We know very little about the role of birds in different ecosystems, despite numerous interesting works of researchers and amateur ornithologist scattered throughout the world. Less attention is paid to freshwater ecosystems because of the difficulties encountered in the experimental methods as well as a lack of interest on behalf of hydrobiologists, for the activities of birds in these ecosystems. This article summarises types and morphoecological forms of waterfowl and their place in the lake ecosystem.

Seasonal variation in the diurnal periodicity of activity of the perch, Perca fluviatilis L. [Translation from: Kalamies 1973(3) 3.]

The most common catch of the amateur angler is the perch and it is the diurnal periodicity of activity (& catchability) which is examined in this study based on earlier articles and manuscripts by the authors. Of all environmental factors, variation in light and temperature are the chief reasons in establishing the times of activity periods. Winter, summer and autumn activity was studied. The spawning perch was found to be more active than the non-spawning perch. The time of day in which the fish may be active is dependant on its ability to sense changes in the external environment. Its adaptation to light is the reason for day-activity in the winter, and also accounts for the fact that hardly any activity occurs between sunset and sunrise when this period exceeds 6 hours.

Desarrollo de una plantilla para analizar el rendimiento de los futbolistas mediante parámetros estadísticos

El objetivo de este trabajo es la creación de una plantilla para el análisis estadístico de los jugadores de futbol. Para el desarrollo y optimización de esa plantilla se ha llevado acabo un análisis con ella de los jugadores suplentes del Sestao River, equipo militante en la segunda división B española. Analizando 65 sujetos en 22 partidos de la temporada 2014/2015. Es una plantilla sencilla y de coste cero pensada para ser utilizada por equipos de futbol amateur y semiprofesional que no disponen de presupuesto suficiente para contar con un servicio de análisis de partidos. La búsqueda de esta sencillez también acarrea unos limites a esta herramienta, las variables analizados son todas acciones con balón porque son las mas fáciles de analizar a primera vista; también existe la limitación de que no se determina en que zona del campo, ni en que momento se desarrolla dicha acción. En cuanto a las limitaciones del análisis llevado a cabo en este trabajo, la principal es que al ser el primer trabajo llevado a cabo con esta plantilla existe una ausencia de datos con los que poder comparar los aquí obtenidos. Por lo tanto en este trabajo se ha realizado un análisis mas descriptivo que se espera en el futuro pueda ser empleado para comparar datos y sacar conclusiones.

Fazendo filmes na Ilha: produção de audiovisual como linha de fuga em Cotijuba, periferia de Belém

Fazendo filmes na ilha investiga as formas com que um grupo de jovens do sexo feminino e participantes assíduas do Cineclube Belém Insular na ilha de Cotijuba (Belém do Pará) se apropriam das imagens produzidas pelos diferentes dispositivos tecnológicos para exprimir as marcas territoriais do ambiente em que vivem. Analisa as produções realizadas por elas e verifica se expressam linhas de fuga às formas e formatos audiovisuais vigentes ou se apenas refletem os clichês visuais e sonoros, além das palavras de ordem, difundidos pelos meios de comunicação de massa. Esta pesquisa surge em decorrência do barateamento, facilidade de manuseio e de transmissão oferecidos pelo desenvolvimento das tecnologias de informação e comunicação, que permitiram novas formas de relação com as imagens. Se antes a produção e difusão das produções audiovisuais eram controladas pelos meios de comunicação de massa no formato um/todos, hoje, qualquer um com telefone celular, câmera fotográfica ou câmera de vídeo amadora é capaz de produzir um filme/vídeo e compartilhá-lo através das redes sociais e, principalmente, através de canais como o youtube. Dessa forma, territórios outrora isolados como a ilha de Cotijuba passam a ter acesso a informações locais e globais que se refletem em novos processos de subjetivação, transformando formas de pensar/agir e sentir na região. O campo conceitual circula entre Foucault, Deleuze e Guattari e outros autores pós-estruturalistas, além da bibliografia específica da área do audiovisual e das artes.

Mídia, esporte e idolatria: o Jornal do Brasil e a representação dos atletas brasileiros nos jogos olímpicos

De maneira ampla, aborda-se nesta dissertação a representação do herói olímpico no Jornal do Brasil na segunda metade do século XX. A hipótese preliminar, seguindo a conclusão de Helal, Cabo e Marques (2009), é que, diferentemente das Copas do Mundo, nas Olimpíadas, os jornalistas esportivos se valeriam de um arcabouço textual distinto para descrever seus objetos de análise os esportes e os atletas e para construir histórias de vida. Enquanto os heróis oriundos do futebol seriam dotados de um talento natural e o treino ocuparia uma posição secundária nas narrativas vitoriosas, os heróis dos ditos esportes amadores alcançariam a glória por meio do esforço abnegado e da dedicação aos treinamentos. Por meio de uma análise das narrativas, tendo como corpus de investigação as edições do Caderno de Esportes do referido jornal ao longo das treze Olimpíadas da segunda metade do século XX de Helsinque-1952 à Sydney-2000 , verifica-se a validade dessa conjectura.

RECITAL REPERTOIRE FOR TROMBONE AND PERCUSSION

The solo trombone recital was once a rare musical event, but in recent years professional and amateur trombonists frequently present solo performances. The trombone has been around since the latter half of the 15th century and there is a wealth of ensemble repertoire, written for the instrument; however, there is no corresponding corpus of solo works. A small body of solo works does exist, from baroque sonatas and the alto trombone concertos of Leopold Mozart and Georg Wagenseil, to the romantic works by Ferdinand David and Nicolai Rimsky-Korsakov. This repertoire is small in number and a modern trombonist often has to resort to orchestral reductions and arrangements for modern performance in a solo recital setting. The trombone came into its own as a solo instrument in the 20th century and it is in this era where the bulk of a modern trombonist's repertoire resides. While there is now no shortage of music to choose from, presenting a diverse, yet musically cohesive recital remains a challenge though many interesting musical opportunities can arise to meet this challenge. While the piano is an extremely versatile instrument, pairing trombone with percussion opens up possibilities that are absent from the more traditional piano pairing. Percussion instruments can offer an almost unlimited variation of timbre and dynamics to complement the trombone. Dynamic range of the trombone must be considered as the instrument has the ability to play at the extremes of the dynamic range. Percussion instruments can match the trombone in these extremes. When presenting a recital of 20th and 21st century music, using timbre and dynamic range as selection criteria when planning the program are effective ways to bring a unique and intense musical experience to the audience. In this paper, the two considerations of dynamics and timbre will be explored and the need for a dissertation recital project will be explained.

Art, biology and technology. Interdisciplinary relations in the science lab

Bio art, understood as the convergence of the relations between art, biology and technology, constitutes a useful case study to discuss the meaning of interdisciplinarity in the artistic field. This paper explores different discourses around interdisciplinarity in order to challenge certain generic approaches for their ineffectiveness when assessing artistic practices. It is proposed that the analysis of interdisciplinarity must address the singular connections produced in the artistic practice itself, considering the impossibility of reducing the complexity of interdisciplinary dialogues into generic considerations. Taking bioart as a case study, different kinds of relationships between the artist and the lab are identified and analyzed, ranging from the use of the lab as a true atelier and as a resource for materials and techniques, to the rejection of the lab by proposing amateurism as an alternative. estrategias amateur, pasando por su utilización como fuente de técnicas y materiales.

Balancing deceit and disguise: How to successfully fool the defender in a 1 vs. 1 situation in rugby

Suddenly changing direction requires a whole body reorientation strategy. In sporting duels such as an attacker vs. a defender in rugby, successful body orientation/reorientation strategies are essential for successful performance. The aim of this study is to examine which biomechanical factors, while taking into account biomechanical constraints, are used by an attacker in a 1 vs. 1 duel in rugby. More specifically we wanted to examine how an attacker tries to deceive the defender yet disguise his intentions by comparing effective deceptive movements (DM+), ineffective deceptive movements (DM-), and non-deceptive movements (NDM). Eight French amateur expert rugby union players were asked to perform DMs and NDMs in a real 1 vs. 1 duel. For each type of movement (DM+, DM-, NDM) different relevant orientation/reorientation parameters, medio-lateral displacement of the center of mass (COM), foot, head, upper trunk, and lower trunk yaw; and upper trunk roll were analyzed and compared. Results showed that COM displacement and lower trunk yaw were minimized during DMs while foot displacement along with head and upper trunk yaw were exaggerated during DMs (DM+ and DM-). This would suggest that the player is using exaggerated body-related information to consciously deceive the defender into thinking he will run in a given direction while minimizing other postural control parameters to disguise a sudden change in posture necessary to modify final running direction. Further analysis of the efficacy of deceptive movements showed how the disguise and deceit strategies needed to be carefully balanced to successfully fool the defender. (C) 2010 Elsevier B.V.

A experiência barroca e a identidade local na Semana Santa de Campanha, Minas Gerais

Este trabalho analisa a formação de uma sensibilidade barroca em Minas Gerais a partir da orientação participativa e altamente emotiva das festas coloniais, cujo legado se mantem presente nas festas religiosas de muitas antigas cidades mineradoras do estado. Enfocando as celebrações da Semana Santa na cidade sul-mineira de Campanha, o texto mostra como este evento anual era organizado pela Irmandade do Santíssimo Sacramento, passando então às mãos de uma comissão local após a extinção da irmandade. Se até meados do século XIX, havia músicos semi-profissionais contratados para tocar e cantar nas celebrações, a música foi assumida progressivamente por grupos de amadores. Assim, a festa passou a ser entendida como uma produção local e a cada ano a população renova o seu orgulho campanhense, ao contemplar sua capacidade de produzir um evento tão ‘maravilhoso’.

This paper analyses the formation of a baroque sensibility in the State of Minas Gerais (Brazil) that derives from the participatory and highly emotive orientation of the colonial festivals, the legacy of which is still present in many former mining towns in the region. By focusing upon the Holy Week celebrations in Campanha, a small town in southern Minas Gerais, the text shows how this annual event was organized by the Confraternity of the Holy Sacrament, but was then transferred to a local committee after the confraternity was made extinct. If up to the mid 19th century there were semi-professional musicians to perform for the celebrations, responsibility for the music was slowly taken over by amateur groups. In this way the festival came to be understood as a local affair, and each year the population renews its pride in itself for its capacity to stage such a ‘marvelous’ event.

SN 2005cs in M51-II. Complete evolution in the optical and the near-infrared

We present the results of the one-year long observational campaign of the type 11 plateau SN 2005cs, which exploded in the nearby spiral galaxy M51 (the Whirlpool galaxy). This extensive data set makes SN 2005cs the best observed low-luminosity, Ni-56-poor type II plateau event so far and one of the best core-collapse supernovae ever. The optical and near-infrared spectra show narrow P-Cygni lines characteristic of this SN family, which are indicative of a very low expansion velocity (about 1000 km s(-1)) of the ejected material. The optical light curves cover both the plateau phase and the late-time radioactive tail, until about 380 d after core-collapse. Numerous unfiltered observations obtained by amateur astronomers give us the rare opportunity to monitor the fast rise to maximum light, lasting about 2 cl. In addition to optical observations, we also present near-infrared light curves that (together with already published ultraviolet observations) allow us to construct for the first time a reliable bolometric light Curve for an object of this class. Finally. comparing the observed data withthose derived front it semi-analytic model, we infer for SN 2005cs a Ni-56 mass of about 3 x 10(-3) M-circle dot a total ejected mass of 8-13 M-circle dot and an explosion energy of about 3 x 10(50) erg.

Audiovisual citation: a project update

Existing referencing systems frequently prove inadequate for the citation of moving image and sound media such as vidcasts, streaming television, sound files, un-catalogued archive footage, amateur content hosted online or
non-broadcast radio recordings. Back in 2009 and 2010 a British working group funded by Higher Education Funding Council for England (HEFCE) and co-ordinated by the British Universities Film and Video Council investigated this problem. This report documents the early stages of the project.

Describing vocal performance of Portuguese cantadeiras of Alto Minho

Portugal has strong musical traditions, which have been perpetrated by decades through folkloristic activities. In folk groups from Alto Minho (north of Portugal), folk singing is mostly performed by cantadeiras, amateur female solo singers who learn this style orally. Their vocal characteristics are distinctive when compared with other regions of the country; however, deep understanding of these vocal practices is still missing. The present work aims at studying Alto Minho cantadeira’s vocal performance in a multidimensional perspective, envisioning social, cultural and physiological understanding of this musical style. Thus, qualitative and quantitative data analyses were carried out, to: (i) describe current performance practices, (ii) explore existent perceptions about most relevant voice features in this region, (iii) investigate physiological and acoustic properties of this style, and (iv) compare this style of singing with other non-classical singing styles of other countries. Dataset gathered involved: 78 groups whose members were telephone interviewed, 13 directors who were asked to fill in a questionnaire on performance practices, 1 cantadeira in a pilot study, 16 cantadeiras in preliminary voice recordings, 77 folk group members in listening tests, and 10 cantadeiras in multichannel recordings, including audio, ELG, air flow and intra-oral pressure signals. Data were analysed through thematic content analysis, descriptive and inferential statistics, hierarchical principal components, and multivariate linear regression models. Most representative voices have a high pitched and loud voice, with a bright timbre, predominance of chest register without excessive effort, and good text intelligibility with regional accent. High representativeness levels were obtained by few cantadeiras; these sing with high levels of subglottal pressure and vocal fold contact quotient, predominance of high spectrum energy and vocal loudness, corroborating indications of prevalence of pressed phonation. These vocal characteristics resemble belting in musical theatre and share similarities with country (USA) and ojikanje (Croatia) singing. Strategies that may contribute to the preservation of this type of singing and the vocal health of current cantadeiras are discussed, pointing at the direction of continuous education among folk groups, following practices that are already adopted elsewhere in Europe.
