Homann, Florian. "Las letras primitivas de los cantes a palo seco, tonás y martinetes: romances narrativos sobre la Prisión General de los Gitanos." Cultura, Lenguaje y Representación 24 (June 15, 2020): 89–104. http://dx.doi.org/10.6035/clr.2020.24.5.
Full textAbstract:
En el mundo flamenco, existe la suposición de que los cantes flamencos contienen unas letras esencialmente líricas que no narran, sin embargo, hay ciertas modalidades, como los cantes a palo seco denominados tonás y martinetes, cuyos soportes literarios derivan de textos más largos y narrativos. Para demostrar que esta consideración es el resultado de un largo proceso de trasformación, se analizan los escritos sobre tonás y martinetes y se compara el contenido de sus coplas con las descripciones de ciertos hechos históricos. En múltiples casos coinciden los fragmentos, aunque sean muy breves, con determinados acontecimientos reales, lo que se puede interpretar como un indicio de que las letras efectivamente derivan de unos textos de romances noticiosos, narrando sobre asuntos carcelarios y la persecución de los gitanos. Uno de los hechos concretos constituye la Prisión General de los Gitanos, realizada en 1749, incluyendo su preparación y sus consecuencias. Así, esta propuesta de buscar el origen de los martinetes, más que en una forma musical, en las letras primitivas, adopta la perspectiva de considerar a los martinetes unos cantos que se han originado como textos narrativos orales, compuestos por los mismos afectados de la medida política sobre la mitad del siglo XVIII y que posteriormente se han convertido, dentro del marco de la cristalización de la cultura musical del flamenco en el siglo XIX, en coplas musicales, asociadas a determinadas melodías del cante a palo seco.

Este artículo pretende explicar por qué escribir en partitura los cantes flamencos y cómo hacerlo para que haya unas mínimas garantías que faciliten que este arte popular no se vea minado en su esencia prístina. La diferencia entre “interpretación” y “re-creación” separa notoriamente la música clásica de la música flamenca, pues mientras aquella utiliza la notación como base para su desarrollo y pervivencia, esta última utiliza esencialmente la trasmisión oral. Por lo tanto cabe preguntarse si es necesario para la pervivencia de los cantes flamencos su trascripción a partituras. Otra cosa bien distinta es si puede hacerse. A esto la respuesta no puede ser otra que sí, aunque a veces con muchas dificultades. No obstante, hay que decir que el escribir los cantes en partitura puede generar tal cúmulo de problemas que afectarían a la esencia de este arte, que debiéramos tomar con muchas precauciones el cómo hacerlo y el qué trascribir.

Desde que Antonio Machado padre publicó su densa colección de Cantes Flamencos (1881), se viene especulando sobre el significado de la palabra debla, que da nombre a la más antigua y dramática de las «tonás», también la más gitana,cuyas raíces se pierden en la profunda noche del cante «jondo». El estribillo («macho») en caló que la remata -Debla barea o deblica barea- ha suscitado múltiples y caprichosas interpretaciones entre los flamencólogos, poco preocupados por el dialecto gitano español y por los préstamos de éste a la copla flamenca, que han llegado a hablar del «misterio» de la debla. El presente estudio viene a deshacer los hilos de un arcano fabricado, al menos desde el punto de vista lingüístico, a partir de una sencilla fórmula exclamativa gitana.

Full textAbstract:
AbstractFlamenco music has consistently been misrepresented as an exclusively aesthetic construct only concerned with the transmission of essential and timeless values and with the production of beauty. This insidious mystification is a consequence of the influence that several decades of nacionalcatolicismo (the ideological construction of Franco's Spain) has had over flamenco, together with its obscure and unclear origins, about three centuries ago. This paper will suggest that, against this commonly held belief, flamenco music frequently has a political agenda, which may be explicitly expressed in the lyrics of the cantes, or implicitly apparent in the formal and ideological structure of flamenco itself and its recordings. Camarón and Pachón's seminal La leyenda del tiempo (Polygram, 1979) will be explored both in its own right as one of the peaks of contemporary (new) flamenco and also as a clear showcase of how flamenco may be politicized in various ways and serve a clearly ideological purpose without neglecting its musical and aesthetic role.

O objetivo deste estudo foi avaliar o ganho de força e potência dos músculos rotadores mediais e laterais do ombro dominante após treinamento pliométrico. Foram avaliadas 10 voluntárias sedentárias que não apresentavam acometimento músculo-esquelético. Todas as voluntárias foram submetidas a uma avaliação física e a uma avaliação isocinética para os movimentos de rotação do ombro dominante, por meio do aparelho isocinético Cybex Norm. Posteriormente, a metade da amostra foi submetida a um programa de treinamento pliométrico para os movimentos de rotação do ombro dominante e a outra metade da amostra formou o grupo controle; após o término do treinamento, as voluntárias sofreram uma nova avaliação isocinética. Os resultados foram analisados estatisticamente utilizando-se o teste t-student não pareado, considerando signifi cantes aqueles com p ≤ 0,05. Os resultados mostraram aumento da força para a musculatura rotadora lateral e aumento de força e potência da musculatura rotadora medial após treinamento pliométrico. Concluímos que o treinamento pliométrico é efi caz para o ganho de força da musculatura rotadora medial e lateral do ombro e, não é tão efi caz para o ganho de potência, apresentando apenas um aumento desta última para a musculatura rotadora medial do ombro dominante. Palavras-chave: treinamento pliométrico, rotadores mediais do ombro, rotadores laterais do ombro, avaliação isocinética.

A beneditina Gertrudes, conhecida como “magna”, nasceu na cidade de Eisleben, Alemanha, em 1256; transcorreu a maior parte de sua vida no mosteiro de Helfta, nas cercanias da mesma cidade, onde faleceu em 1302. Dotada de inteligência e sensibilidade, com 25 anos de idade passou por um processo de conversão: deixou a avidez pelas Artes Liberais e iniciou uma intensa experiência do amor de Deus (divina pietas) – donde o título de sua obra-mestra Legatus divinae pietatis (Mensageiro do amor divino), seguida pelos Exercitia spiritualia (Exercícios espirituais). De postura cristocêntrica, Gertrudes enaltece a graça divina sobre todo mérito individual. Sua obra alcançou grande infl uência no Ocidente, com muitas reedições, a partir do século XV. Neste estudo, apresentamos os traços fundamentais de seu itinerário místico, para concentrar-nos em seguida em sua experiência do Espírito Santo. Procedemos a uma leitura pneumatológica do Legatus divinae pietatis, para recolher e expor teologicamente a contemplação trinitária do Paráclito em Gertrudes, sua recepção dos sete dons santifi cantes, os carismas que manifesta e, por fi m, sua experiência do novo Pentecostes. Além das fontes bíblicas, litúrgicas e patrísticas muito citadas, Gertrudes testemunha uma peculiar e feminina experiência do Espírito que consola, instrui e renova sua pessoa integralmente. A análise dos textos revela-nos uma pneumatologia narrativa e vivencial, que, em alguns aspectos, antecede as características do avivamento pentecostal moderno.

A complexidade anatômica dos canais radiculares, por exemplo, sua forma, curvatura e diversidade da curvatura do raio, bem como a presença de istmo de alto índice e canais laterais, são fatores importantes a serem levados em consideração na terapia endodôntica. Assim, o objetivo neste estudo foi avaliar o preenchimento total de canais laterais simulados com dois diferentes cimentos endodônticos. Foram utilizados 8 dentes anteriores extraídos por razões periodontais. Foram confeccionados canais laterais com uma broca carbide esférica ¼ a uma distância de 4 mm do ápice radicular. Em seguida, os dentes foram radiografados no sentido anteroposterior. Os canais radiculares destes dentes foram preparados utilizando-se de um sistema reciprocante 25.08 acionados por motor elétrico X Smart Plus até o comprimento de trabalho utilizando hipoclorito de sódio 2,5% como solução irrigante. Os dentes foram divididos em 2 grupos (n=4) de acordo com diferentes cimentos endodônticos (AH Plus ou Bio C Sealer). Os canais foram secos com pontas de papel absorvente, depois foram preenchidos com cone médio e diferentes cimentos endodônticos. O preenchimento total de canais laterais simulados foram avaliados a partir de novas radiografias digitais realizadas após obturação dos dentes. Os canais laterais simulados não foram completamente preenchidos, independentemente do cimento endodôntico utilizado, e os resultados demonstraram que os diferentes cimentos avaliados não preencheram os canais radiculares laterais simulados.

Abstract
The anatomical complexity of root canals, for instance, their shape, curvature and radius curvature diversity, as well as the presence of high index isthmus and lateral canals are important factors to be taken into consideration in endodontic therapy. Thus, the aim of the present study was to assess complete filling of simulated lateral canals with two different endodontic cements. Eight anterior teeth extracted due to periodontal reasons were used in the experiment. Lateral canals were opened with ¼ spherical-shaped carbide drill 4 mm away from the root apex. Teeth were subjected to X-ray in anteroposterior position. The root canals of these teeth were prepared with the aid of a 25.08 reciprocating system in electrically driven motor X Smart Plus for its working length by using 2.5% sodium hypochlorite as irrigating solution. The teeth were divided into 2 groups (n=4) according to different endodontic cements (AH Plus or Bio C Sealer). Root canals were dried with paper points, afterwards were filling with medium cone and different endodontic cements. The complete filling of simulated lateral canals was assessed based on new digital radiographs taken after teeth filling. The simulated lateral canals were not completely filled, regardless of the used endodontic cement. Results have shown that the different assessed cements did not fill the simulated lateral root canals.

This study aimed to characterize fishing boats in the municipality of Santarém. The data were collected through interviews carried out from January 2017 to December 2018, in places where the fishing fleet was busy and at various points the edge of the city. During this period, 150 semi-structured forms were applied mainly to the owners or agents of fishing boats and fishermen who landed fish, as well as the monitoring of landings and direct observations. The fishing boats in activity in the municipality and registered in the present study had dimensions varying from 3 to 20 meters in length, all units of the fishing fleet had the construction and structure in wood evidencing an artisanal production system. The fishing fleet was classified into seven categories: “cascos”, canoes, motorized canoes, “sapiaras”, “rabetão”, “bajaras” and “geleiras”, which differ in size, model and type of propulsion. The most frequent boats in the ports of Santarém were the group of canoes, in descending order of contribution, are the “rabetas”, canoes, “cascos”, “rabetão” and “sapiaras”, followed by the glaciers and “bajaras” boats. The physical conditions of the floodplain environment, with numerous canals, “paranás” and lakes that suffer fluctuations of the water level are determinant factors for the size of the boats justifying the great use of the hooves and canoes actually operating in the regional fishing activity, associated with a variation of fishing techniques that demand a differentiated means of transport. Therefore, this study proves that the fishing sector plays an important role in the regional economy, besides supplying the Santarém city.

ABSTRACTInvasive mycotic infections have become more common during recent decades, posing an increasing threat to public health. However, despite the growing needs, treatments for invasive fungal infections remain unsatisfactory and are limited to a small number of antifungals. The aim of this study was to identify novel fungal cell wall inhibitors from a library of small chemical compounds using a conditional protein kinase C (PKC)-expressing strain ofAspergillus nidulanssensitive to cell wall-active agents. Eight “hit” compounds affecting cell wall integrity were identified from a screen of 35,000 small chemical compounds. Five shared a common basic molecular structure of 4-chloro-6-arylamino-7-nitro-benzofurazane (CANBEF). The most potent compound, CANBEF-24, was characterized further and was shown to inhibit the growth of pathogenicAspergillus,Candida,Fusarium, andRhizopusisolates at micromolar concentrations but not to affect the growth of mammalian cell lines. CANBEF-24 demonstrated strong synergy in combination with caspofungin, an antifungal that inhibits cell wall biosynthesis. Genetic and biochemical analyses withAspergillus nidulansandSaccharomyces cerevisiaeindicated that CANBEFs selectively inhibit fungal rRNA maturation and protein synthesis, suggesting that their effect on the cell wall is indirect. CANBEFs were nontoxic in insect (Galleria mellonella,Drosophila melanogaster) and mouse models of fungal infection. Preliminary evidence showing no therapeutic benefit in these models suggests that further cycles of optimization are needed for the development of this novel class of compounds for systemic use.

The structure of 8-oxo-5,10,15,20-tetraphenyl-7-oxaporphyrinN24-oxide, C43H28N4O3, (4B), shows thatN-oxidation of the pyrrole opposite the oxazolidone group cants the pyrrole out of the mean plane of the chromophore. This also affects the oxazolidone group, which is also slightly canted out. This conformation is qualitatively similar to that of the parentmeso-tetraphenylporphyrinN-oxide, but dissimilar to that of the porpholactoneN-oxide isomer 8-oxo-5,10,15,20-tetraphenyl-7-oxaporphyrinN22-oxide, (4A), carrying theN-oxide at the oxazolidone group. While the degree of canting of theN-oxidized groups in both cases is comparable (and more pronounced than in the porphyrinN-oxide case), in (4A) the pyrrolic groups adjacent to theN-oxidized group are more affected than the opposing group. These differences in the conformational modes may contribute to rationalizing the distinctly different electronic properties of (4A) and (4B).

A gestão de resíduos é um tema global de grande relevância na atualidade devido a vários fatores. No Brasil, a questão da disposição do lixo e tratamento de resíduos sólidos ainda está pouco amadurecida e não se encontra equacionada à outras atividades do Estado. O crescimento exponencial da distribuição espacial dos lixões tem como palco privilegiado as metrópoles. Em Belém, a espacialidade dos lixões é diversa e encontram-se por todo o município em terrenos baldios, cantos de ruas e beira de canais. Tal fato é recorrente há anos tornando-se um grande desafio que só poderá ser resoluto através de um amplo rol de cooperação entre o poder público e a sociedade civil com base em políticas públicas e educação ambiental, entre outros. Assim, este trabalho objetiva fomentar o debate sobre a responsabilidade do Estado no que diz respeito à existência e espacialização de depósitos irregulares de lixo urbanos nas margens de canais, situados em zona periférica do município de Belém. Os procedimentos ajudaram a constatar que os depósitos irregulares de lixo se espalham homogeneamente por todos os lados em quantidades diferenciadas, sobretudo de entulho, madeira/podas de árvores e lixo doméstico.

Full textAbstract:
The period since the establishment of the European Economic Community in 1957 has been marked by important socio-demographic changes. The population of the European Union has been ageing, family size has declined, and the family unit has become less institutionalized, placing strains on intergenerational relationships. The combination of economic, political and socio-demographic change has posed threats for social protection systems, economic performance and individual well-being, while also offering opportunities for policymakers in EU member states to review policy options, the efficacy of existing policies and the need for reform. This article examines how socio-demographic change and the social problems associated with it are experienced and perceived in different national contexts, and analyses the policy responses of governments. The outcomes of policy measures formulated and implemented by national governments are reviewed in terms of their possible impact on socio-demographic trends. The article argues that socio-demographic change would appear to have an influence on policy measures, but convincing and consistent evidence is difficult to find in support of claims that policy has a determining effect on socio-demographic trends. In conclusion, the potential for further development of social policy at EU level is considered, both in response to socio-demographic challenges and as a means of managing change. Résumé Depuis l'établissement de la Communauté économique européenne en 1957, d'impor-tants changements socio-économiques ont eu lieu. La population de l'Union européenne a vieilli, la taille des familles s'est réduite et la famille en tant qu'unité est devenue moins institutionnalisée exerçant ainsi des pressions sur les relations intergénérationnelles. La combinaison de changements économiques, politiques et démographiques constitue une menace pour les systèmes de protection sociale, les performances économiques et le bien-étre individuel. Toutefois, cela offre également la possibilité pour les décideurs politiques dans l'Union européenne de réex-aminer leur options politiques, l'efficacité des politiques menées et la nécessité de réformes. Cet article examine comment les change-ments socio-démographiques et les problèmes sociaux qui leurs sont associés, sont perçus dans différents contextes nationaux. Il analyse également les réponses politiques que les gouvernements leur ont données. Les résultats des mesures politiques élaborées et mises en place par les gouverne-ments nationaux sont passés en revue en fonction de leur impact possible sur les ten-dances socio-démographiques. Cet article défend l'hypothèse que les changements socio-démographiques semblent avoir eu une influence sur les mesures politiques, alors qu'il est difficile de trouver des preuves convain-cantes et consistantes que la politique ait eu un effet déterminant sur les tendances socio-démographiques. en conclusion, l'éventualité de développements ultérieurs de la politique sociale européenne est envisagée, du point de vue de la réponse aux défis socio-économiques et en tant que moyen de gérer le changement.

Physiol. 82(4): 1035–1039, 1997.—The effect of inhibition of nitric oxide production on sweating rate (SR) and on core, rectal, and tail skin temperatures was measured in five Thoroughbred horses during exercise of variable intensity on a high-speed treadmill. A standard exercise test consisting of three canters [∼55% maximum O2 uptake (V˙o 2 max)], with walking (∼9%V˙o 2 max) and trotting (∼22% V˙o 2 max) between each canter, was performed twice (control or test), in random order, by each horse. N G-nitro-l-arginine methyl ester (l-NAME; 20 mg/kg), a competitive inhibitor of nitric oxide synthase, was infused into the central circulation and induced a significant reduction in the SR measured on the neck (31.6 ± 6.4 vs. 9.7 ± 4.2 g ⋅ min−1 ⋅ m−2; 69%) and rump (14.7 ± 5.2 vs. 4.8 ± 1.6 g ⋅ min−1 ⋅ m−2; 67%) of the horses during canter ( P< 0.05). Significant increases in core, rectal, and tail skin temperatures were also measured ( P < 0.05).l-Arginine (200 mg/kg iv) partially reversed the inhibitory effects ofl-NAME on SR, but core, rectal, and tail skin temperatures continued to increase ( P < 0.05), suggesting a cumulation of body heat. The results support the contention that nitric oxide synthase inhibition diminishes SR, resulting in elevated core and peripheral temperatures leading to deranged thermoregulation during exercise. The inhibition of sweating byl-NAME may be related to peripheral vasoconstriction but may also involve the neurogenic control of sweating.

O artigo resulta de uma pesquisa etnográfica realizada entre os povos Timbira, tratando de categorias de cantos tal como classificados por esses povos. Apresentaremos aqui as formas dos vários povos Timbira classificar os cantos. Os Ràmkôkamẽkra/Canela e os Apỹnjekra/Canela os classificam em: comuns e pequenos, que são cantos de outros povos utilizados para brincar no pátio; os cantos comuns, que são aqueles alegres e bonitos, que são organizados e sistemáticos, porém não são especiais; e os cantos principais, belos, verdadeiros, que são especiais e organizados sistematicamente. Os Krahô dividem os cantos de pátio em: cantos para divertir, cantos sérios e cantos verdadeiros. Já os Apinaje classificam os cantos de pátio dividindo-os entre cantos de diversão aleatoriamente executados e cantos sérios e sistematicamente organizados e executados. Entre os Krĩkati e Pyhcop caitiji/Gavião os cantos são divididos em duas classes: os de diversão do início da noite e os cantos sérios, executados durante a madrugada. Argumentamos que, a despeito das variações linguísticas entre os Timbira, os cantos são executados em um único idioma musical, havendo variações musicais performáticas que dão especificidades quer a cantores, quer a povos distintos. Além disso, é preciso pensar em uma rede entre os Timbira para entender seu universo musical e para compreender o processo de formação dos novos cantores que precisam conhecer esse universo, o idioma musical, a rede e as performances. Para ampliar o nosso diálogo etnográfico, estabelecemos comparações com outros sistemas, como o do Xingu e do Alto Rio Negro.

Full textAbstract:
Low lake levels, due to drought in spring and summer 2000, revealed the decayed remnants of over 100 dugout canoes buried in the sediments of Newnans Lake near Gainesville, Florida. Radiocarbon assays revealed that 41 of 55 canoes studied were from the Late Archaic period, dating between 2300 and 5000 B.P. Analysis of canoe form and comparison to the small number of other known Florida Archaic period canoes correct previous ideas about early canoes. Patterns of wood choice and manufacturing techniques known from younger canoes were in place during the Late Archaic. The Archaic period canoes from Newnans Lake are indistinguishable from canoes produced in later periods and are not the crude, short, blunt-ended type thought to represent the earliest dugout canoes. Thwarts or low partitions on almost half of the Archaic canoes studied confirm a long temporal span to the canoe-making tradition of peninsular Florida. Middle and Late Archaic groups had boat-building and related technologies in place 7,000 years ago and were expanding into areas with newly emerging freshwater resources created by higher water tables.

El siguiente artículo presenta los resultados de la investigación desarrollada desde y con el pueblo Embera Eyábida de Chigorodó sobre los cantos ancestrales de las mujeres y su vinculación con los espacios pedagógicos y didácticos de las escuelas indígenas. Como pregunta de investigación se planteó ¿Qué elementos pedagógicos pueden aportar los cantos ancestrales al modelo de educación propia que se ejerce dentro de las escuelas indígenas de la comunidad Embera Eyábida?El objetivo de la investigación fue recuperar cantos ancestrales o truambis de las mujeres abuelas de este pueblo indígena, para construir material pedagógico que aporte a la educación propia de los niños y niñas. El trabajo se inscribió dentro del paradigma de investigación indígena sustentando por Linda Smith y profundizó el método de investigación Embera adelantado por el lingüista indígena de pueblo Embera Dobida, Baltasar Mecha.Encontramos que existen cinco tipos de cantos ancestrales o truambis en el pueblo Embera de Chigorodó: cantos de animales, cantos de sanación, cantos de duelos, cantos de arrullos y cantos de parejas. Estos cantos ancestrales se encuentran en riesgo de desaparecer si no se realizan procesos pedagógicos que fortalezcan y visibilicen su práctica. Las amenazas del sistema dominante están desvirtuando los intereses de la niñez y las juventudes Embera, enrutándoles a asimilar perspectivas occidentales en sus prácticas culturales que afectan notoriamente el arraigo identitario. Aprendimos que en la actualidad el grupo poblacional que practica y enseña estos conocimientos, está integrado por las mujeres Embera Eyábida, quienes a su vez son guardianas y pedagogas de la sabiduría ancestral. Se hace urgente reconocer y profundizar en sus saberes para fortalecer la memoria comunitaria del pueblo Embera.

Several canoes were excavated from coastal rivers in the Guangxi Zhuang Autonomous Region, southwest China. In order to confirm the age of the canoes, 6 samples were selected for radiocarbon dating from 3 canoes. The mean value of canoe NLJ was 365 ± 35 BP, and 2 samples from canoes MLJ and DFJ were 520 ± 21 and 499 ± 33 BP, respectively. The calendar ages cover a period from AD 1328 to 1641 at the 95% confidence level. These results disagree with previous studies that suggested canoes were only used over 1000 yr ago in China. We discuss the possible reasons for the results being younger than expected.

La tesi di una evoluzione di /s/ in posizione finale in /y/, nell'area che include toscano, dialetti italiani centro-meridionali e balcano-romanzo (veglioto, romeno) era già stata avanzata da Reichenkron (1939). In tale area sia parole monosillabiche che polisillabiche presenterebbero questo sviluppo. Ad esemplificare le prime sono chiamate in causa forme come rom. e it. dai < DAS, rom. e it. stai < STAS, rom. e it. poi < POS ( < POST), it. centr. e merid. crai < CRAS, it. merid. ccuy e it. più < PLUS, rom. e it. merid. trei < TRES, oltre per l'appunto, alle forme pronominali rom., vegl. e it. noi < NOS e voi < VOS. Nei polisillabi questo sviluppo si mostrerebbe con minore evidenza, perché qui /y / si sarebbe fusa con la vocale atona precedente, o sarebbe caduta: si pensi all'it. ant. cante (it. mod canti), tosc. sett. canta, rom. cânţi < CANTAS; it. vedi, rom. vezi < VIDES, e così via.

Full textAbstract:
Parent canes of Willamette raspberry produced more vigorous canes than those of Glen Clova although the latter was less prone to bud failure in the first year. Reducing the length of the parent canes encouraged cane production and lowered the incidence of bud failure. Freshly dug plant material had more canes and less bud failure than those stored at 2�C, particularly when planted during June-July. For all treatments, the percentage of fruiting canes was 2-3 times higher in the second growing season than in the first, despite the total number of canes being less.

Full textAbstract:
The argument of Kindellan and Kotin's essay, ‘The Cantos and Pedagogy’, is that, contrary to the prevailing critical view, The Cantos is not a pedagogical poem. More specifically, they argue that the poem rejects the idea that a methodological approach to knowledge is desirable. The Cantos is obsessed with who we are, not what we can learn. Put otherwise, the horizon of Pound's concern in The Cantos is ontological, not epistemological. Charles Altieri, Alan Golding, Marjorie Perloff, and Steven G. Yao and Michael Coyle challenge this claim. The range of their replies demonstrates the breadth of the problem at hand. They all construe The Cantos as embodying an alternative pedagogy rather than, as Kindellan and Kotin argue, an alternative to pedagogy.

Full textAbstract:
Limb contact variables of the gaits of dressage horses were determined for competitors at the 1988 Seoul Summer Olympic Games in the team and individual dressage competitions. Two 16-mm motion picture cameras filming at 100 fps were aimed perpendicular to the plane of equestrian motion along the HXF and MXK diagonals of the standard dressage arena. Eighteen competitors in team dressage were filmed during the Grand Prix test while executing the extended walk, extended trot, and left lead extended canter. Fifteen horses selected as finalists for individual dressage medals were filmed during the Grand Prix Special test executing the extended trot, one-stride canter lead changes, two-stride canter lead changes, and the left lead extended canter. Velocities of the extended walk, extended trot, and extended canter were positively related to stride length. Velocities of the Grand Prix extended walk and Grand Prix Special extended trot were positively related to stride frequency. Limb contact patterns of the extended walk stride appeared to have relatively little importance in scoring. Certain characteristics of the extended trot and extended canter were strongly related to scores attained in Grand Prix Special dressage tests, with highest scores achieved by horses with the longest, fastest strides. For canter strides involving lead changes, no limb contact variables were detected that were significantly related to scores. This study provided the first objective documentation of the limb contact patterns of the walk, trot, and canter of world-class dressage horses.

Full textAbstract:
ABSTRACTThis is the first study to examine the seven invitatory antiphons of the Birgittine weekly Office, the Cantus sororum, offering complete transcriptions of the melodies and texts. An important general finding is that these invitatories share many melodic similarities with great responsories, but on a more detailed level this article investigates precisely how these chants relate to known models, both complete melodies as well as individual melodic motives. Four patterns of composition among the Cantus sororum invitatories emerge: (1) unique texts may be combined with melodies that resemble other known chants outside the Cantus sororum; (2) texts and melodies that resemble other variants outside the Cantus sororum may be combined in new ways; (3) both text and melody are unknown outside the Cantus sororum.Overall, these invitatory antiphons, like the rest of the Cantus sororum, represent creative work with existing melodies and texts, including reworkings, borrowings and consistent use of melodic motifs, comprising a significant part of a repertoire at once distinctly Birgittine in character and yet conforming to the common stock of Gregorian Chant. Melodic correspondences within the Cantus sororum as well as in the Birgittine Mass repertoire thus afford an interesting perspective on a soundscape in which the Birgittines functioned and where, through music, their identity was created and maintained.

En el presente trabajo se determinó la respuesta inmune posterior a las campañas de vacunación antirrábica masiva realizadas en 19 distritos de la ciudad de Lima. El método utilizado fue la titulación de anticuerpos antirrábicos mediante la prueba de seroneutralización en ratón, técnica que fue aplicado a un muestreo significativo de sueros sanguíneos de la población de canes vacunados. Se tomaron al azar 54 muestras de canes mordedores que ingresaron al Centro Antirrábico de Lima para ser observados clínicamente por un periodo de 10 días. De las 54 muestras de suero que se sometieron a la prueba, 28 (52%) fueron positivos (títulos de 0,5-8,39 UI/ml), mientras que las 26 (48%) muestras restantes dieron títulos inferiores a 0,5 UI/ml y otros fueron negativos a la prueba. El grupo etáreo de mayor muestreo correspondió a la población de canes de más riesgo (1-3 años de edad). En este grupo etáreo, 14 canes (26%) presentaron sueros con títulos de protección, mientras que en 18 canes (33%) la prueba fue negativa. En lo referente al sexo, el grupo de canes machos (considerados de mayor riesgo) presentaron mayor número de individuos (44 canes) respecto al grupo de hembras (10 canes) y solo en 24 canes machos (45%) dieron títulos de protección antirrábica. En conclusión, podemos decir que el 52% de canes vacunados durante las anteriores campañas de vacunación antirrábica masiva en la ciudad de Lima, en 1993, tuvieron títulos de anticuerpos protectores contra el virus de la rabia.

El Warime es una modalidad de yuruparí que festejan los piaroas de la Orinoquia venezolana y colombiana. Durante su desarrollo se generan cuatro escenarios de comunicación musicalizada, dos de diálogos y dos de monólogos. Coinciden los diálogos profanos en medio de monólogos sagrados, los cantos sagrados de estructura rígida respondidos por cantos profanos de contenidos personalizados. Concluimos que los cantos profanos en respuesta a los cantos sagrados son la humanización de la relación, que los encuentros dialogados son posibles allí donde hay equidad sin peligro, mientras que los monólogos se dan donde la comunicación está verticalmente jerarquizada.

This paper focuses on the structural analysis of concrete canoes. It firstly introduces the background of the concrete canoe competition and some typical FEA methods for concrete canoes. Then the paper establishes and analyzes an FEA model with SAP2000. Considering the similarity between concrete canoes and strip foundations under column, the paper uses the foundation engineering theory of strip foundations under column to determine the support conditions, and the applied loads of concrete canoes under 2 key loading cases. The result is proved to be accurate according to the experience of Tongji University Concrete Canoe Team. Finally, a conjecture of partial plane cross-section assumption of concrete canoe is proposed according to the result of FEA.

Full textAbstract:
Using the rotating cross-arm (RCA) trellis and cane training system, lateral canes of trailing ‘Siskiyou’ blackberry (genus Rubus subgenus Rubus) were kept vertically or rotated down to horizontal so that plant canopy was close to the ground. In winter, the plots were either covered with a non-woven rowcover (RC) or left uncovered. Cane injury was least in plants with lateral canes oriented horizontally and covered. Cane injury was high in plants with lateral canes oriented vertically in winter, whether covered or not, and among plants with lateral canes laid close to the ground but not covered. Among ‘Siskiyou’ plants that had lateral canes oriented horizontally, 280 flower clusters and 6.0 kg fruit/plant were produced on plants that had a RC in the winter compared with only 72 flower clusters and 1.7 kg fruit/plant for plants that were not covered in winter, in 2009. Fewer flower clusters developed and the yield was ≤2 kg/plant on plants with lateral canes oriented vertically. Yield differences between the most and least productive treatments were low in 2010 because of milder winter conditions and snowfall during the coldest periods that fully or partially covered the lateral canes oriented horizontally and close to the ground. The RC treatment had no effect on cane injury or yield when lateral canes were oriented vertically. The findings suggested that ‘Siskiyou’ blackberry can be grown in the eastern United States, where winter injury has frequently caused a crop failure, by positioning the lateral canes close to the ground and covering plants with a RC.

Full textAbstract:
1. Coordinate transformation between vestibular and oculomotor reference frames is required to produce compensatory, vestibuloocular reflex (VOR) eye movements in view of the differing, although similar, peripheral three-dimensional geometry of the semicircular canals and the extraocular muscles. This transformation requires convergence of canal-specific signals at some level in the VOR arc. 2. To investigate the networks that underlie the transformation between oculomotor and vestibular reference frames for spatial coordination of compensatory eye movements, we recorded intracellularly in decerebrate cats from 93 identified second-order vestibulooculomotor and abducens internuclear neurons in the medial longitudinal fasciculus (MLF) between abducens and trochlear nuclei and characterized their spatial response properties. Neurons were classified according to whether they were activated from the labyrinth ipsi- or contralateral to the recording site and according to the canal from which they received their strongest input. Our data revealed neurons that carried single- and multiple-canal signals. 3. Twenty-two neurons received their primary input from the ipsi- or contralateral anterior canal (AC). Ten nonconvergent AC neurons responded maximally to rotation in a plane within 10 degrees of the AC plane, whereas 6 AC neurons received sufficient convergent input from the orthogonal vertical canals to shift their plane of maximum response > 10 degrees from the AC plane. Of 29 ipsi- and contralateral posterior canal (PC) neurons, 9 were non-convergent, whereas 13 received sufficient convergent input from the orthogonal vertical canals to shift their response plane > 10 degrees from the PC plane. The rotational responses of 6 AC and 12 PC neurons indicated that they received convergent input from the horizontal canals. However, when these responses were averaged, the horizontal responses tended to cancel, leaving little net population response to horizontal rotation. We also encountered 19 ascending axons of second-order neurons activated primarily from the horizontal canals. Nine of these received significant input from the vertical canals, but the mean population response was within 4 degrees of the horizontal canal plane. 4. Our results demonstrate single canal responses and specific canal-canal convergence within the population of vertical vestibulooculomotor neurons. This convergence is thought to participate in the coordinate transformation within the specific geometry of the VOR system. The data indicate response shifts of a population of AC neurons toward the plane of the inferior oblique muscle, and of a population of PC neurons toward the plane of the superior oblique muscle. Conspicuously absent are neurons that fall into the plane of either the superior rectus or the inferior rectus muscles. (ABSTRACT TRUNCATED AT 400 WORDS)

Renewed interest in red raspberry production in Colorado has been limited by winter kill of canes. Winter kill in Colorado may be the result of extreme cold temperatures, desiccation, or a combination of the two. We are evaluating winter protection strategies to increase survival and to better understand the winter stress of raspberries. The four (4) cane treatments of red raspberry, Rubus ideaus L. cv. Heritage, used were (1) canes bent and wrapped with plastic; (2) canes bent and mulched with hay and soil; (3) canes upright with anti-desiccant spray; (4) a control of canes upright without protection. Moisture content and electrolyte leakage were evaluated at intervals. Relative moisture loss was greatest in the control as compared to the other treatments. The terminal sections of the canes exhibited greater moisture loss as compared to basal sections in the control with a similar trend in the other treatments. Relative survival as indicated by electrolyte leakage was monitored and will be correlated with moisture loss.

Os cantos de maracá são um gênero verbo-musical pan-timbira, executado cotidianamente no pátio das aldeias e também em contextos rituais. A análise deste material nos permitirá identificar e descrever algumas das concepções krahô sobre os modos de execução, transmissão, circulação e fruição dos cantos de maracá, concepções que são fundamentais tanto para a compreensão do regime sociocosmológico de memória que é próprio a esta forma de conhecimento quanto para a compreensão do lugar que cantores e cantoras ocupam no socius krahô e no sistema regional formado pelos povos timbira.

Canes and flower buds of selected red raspberry cultivars (Rubus idaeus L. `Maurin Makea', `Muskoka', and `Ottawa') were sampled from a field (latitude, 61 °20'N; longitude, 24 °13'E) at 1-month intervals during Winter 1996-97 to study the interaction of dormancy and cold hardiness, hardiness retention, and rehardening capacity. One set of canes was subjected to dehardening (3 days) and two sets to dehardening + rehardening (3 and 7 days) treatments before cold hardiness determination. Maximum midwinter hardiness occurred in January, after breaking of endodormancy. Cold hardiness of canes and buds reached -28.6 to -37.2 °C and -24.2 to -31.6 °C, respectively. Throughout the winter, raspberry canes were hardier than buds. Endodormancy had a greater influence on dehardening and rehardening in buds than in canes, and cultivars differed in their response. Dehardening of `Maurin Makea' canes and buds, and `Muskoka' buds was slightly enhanced by breaking of dormancy, whereas dehardening in `Ottawa' was not affected by dormancy. Raspberry canes and buds could reharden even after dormancy release. Rehardening capacity was affected by the state of dormancy only in `Maurin Makea' buds. Changes in dormancy status failed to explain cultivar differences regarding dehardening and the capacity to reharden suggesting other factors may be involved.

El estudio tuvo como objetivo determinar indicadores demográficos de la población de canes y gatos domésticos con dueño en asentamientos humanos del distrito de Ventanilla, Callao (Perú). Se realizó un muestreo por conglomerado para seleccionar los grupos poblacionales y un muestreo estratificado y sistemático para seleccionar las viviendas. La información fue recolectada mediante una encuesta. Se calcularon las características demográficas de la tenencia de canes y gatos, y la relación can:persona y gato:persona. El 61.9 y 40.0% de las viviendas poseían canes y gatos, respectivamente. El número de mascotas por vivienda fue de 1.8 para ambas especies. El número de crías en los canes fue de 4.3 y en gatos de 3.1. La tasa de supervivencia estimada de las crías fue de 56.2 ± 3.0% en canes y de 66.4 ± 3.9% en gatos. La esperanza de vida estimada fue de 4.21 ± 0.44 años en canes y de 2.64 ± 0.46 años en gatos. Se estimó que existía 1 can por cada 3.98 personas y 1 gato por cada 5.34 personas. El 23% de encuestados manifestó mantener canes vagabundos en el exterior de las viviendas. Se espera que la información ofrecida sirva a las autoridades de salud para planificar programas de control poblacional y tenencia responsable de animales de compañía en esta población.

Full textAbstract:
Treatments of either staked (stabilized) or not staked (control, freestanding) canes were applied to Rubus idaeus L. `Boyne' and `Regency' during the 1997 and 1998 seasons to determine the effect of stabilizing fruiting canes in a windy environment. Treatments were applied in late April of each year, and canes were removed following harvest for growth analysis. Stabilizing (staking) floricanes increased yield per cane in `Boyne' by 68% and in `Regency' by 189%, primarily through increases in fruit number per cane. Leaf area of the staked canes was 41% larger for `Boyne' and 159% for `Regency' than that of the control canes, suggesting that more leaf area was retained for photosynthesis, resulting in greater yield. Primocane diameter in `Boyne' and primocane height in `Regency' were also increased by staking, but floricane structure was unaffected.

El objetivo del estudio fue evaluar los conocimientos y prácticas asociados al cumplimiento de la Ley N.° 27596, Ley que Regula el Régimen Jurídico de Canes, en pobladores de distritos de Lima Metropolitana. Se diseñó y validó una encuesta que incluyó variables sobre conocimientos y prácticas asociadas a los principales aspectos normativos de la mencionada ley, y se aplicó en espacios públicos a tenedores de canes de 20 distritos de estratos socioeconómicos alto, medio y bajo. La participación en el estudio fue voluntaria, obteniéndose 783 encuestas. El 67.6% conocía que existían razas potencialmente peligrosas (nombraron a Pitbull y Rottweiler) y el 24.9% conocía la existencia de requisitos para su tenencia. El 35.1% afirmó que la castración disminuía la agresividad de los canes y 24.8% opinaron que los canes deben de ser adiestrados en centros especializados. El 95% afirmó que el dueño del can debe asumir los daños que produce su can, el 29.4% sabía que los dueños de canes de razas potencialmente peligrosas deberían tener un seguro contra accidentes y el 58.7% reconocía que la Policía Nacional debería auxiliar a las víctimas de mordedura de canes. El 12.8% reconoció que sus canes habían mordido y el 72.0% asumió los gastos ocasionados por su can. La práctica de recojo de heces y paseo de canes fue mayoritaria, pero la de identificación, registro en la municipalidad y control reproductivo de canes fue limitada. El 14.3% afirmó haber recibido charlas de tenencia responsable de animales de compañía, 16.2% escuchó sobre la Ley N.° 27596 y el 8.4% sabía que existía una Ordenanza Municipal con relación a dicha ley en su distrito. Se hace necesario una mayor difusión de la Ley N.° 27596 y así como una exigencia para su aplicación.
