Lycaenid caterpillars (Lepidoptera, Lycaenidae) eating flowers of Dalea pennellii var. chilensis (Fabaceae) in the northern Chilean Andes

Lycaenid caterpillars (Lepidoptera, Lycaenidae) eating flowers of Dalea pennellii var. chilensis (Fabaceae) in the northern Chilean Andes. The shrub Dalea pennellii var. chilensis (Fabaceae) is reported for the first time as a host plant for three Neotropical Polyommatini (Lepidoptera, Lycaenidae, Polyommatinae): Hemiargus ramon (Dognin, 1887), Leptotes trigemmatus (Butler, 1881) and Nabokovia faga (Dognin, 1895), based on two collections performed in the western slopes of the northern Chilean Andes in two consecutive summers. The relative abundance was always above 90% for N. faga while it was always less than 5% for H. ramon and L. trigemmatus. Furthermore, N. faga was not found on inflorescences of other native Fabaceae examined in the study site. This pattern suggests a close relationship between N. faga and D. pennellii var. chilensis, at least at a local scale.

School Choice and Student Screening in the Chilean Educational System: Who Chooses Whom?. The Case of the Catholic Education

The student´s screening made by schools corresponds to a regulatory mechanism for school inclusion and exclusion that normally overlaps the parental expectations of school choice. Based in "Parents survey 2006" data (n=188.073) generated by the Chilean Educational Ministry, this paper describe the parents reasons for choosing their children's school, and school´s criteria for screening students. It concludes that the catholic schools are the most selective institutions and usually exceed the capacity of parental choice. One of the reasons to select students would be the direct relationship between this practice and increasing the average score on the test of the Chilean Educational Quality Measurement System (SIMCE).

Estudi estratègic del coblisme com a bé cultural

Aquest treball de final de carrera tracta sobre l’aplicació de les modernes tècniques de reflexió estratègica aplicades al sector de la cultura popular catalana, concretament la cultura popular catalana que engloba les manifestacions on el vincle comú és la formació musical pròpia: la cobla. Aprofitar aquest sector, a priori tant complex i tant allunyat en principi del món d’estratègia d’empresa com aquest, és l’excusa per veure el comportament d’aquestes eines i teories, i comprovar-ne la seva eficàcia i adaptabilitat als diferents casos de la realitat, a més de poder treballar un tema tant nou com la valoració d’intangibles. A la vegada, es produeix una síntesi de treballs orientats a l’organització d’entitats sense ànim de lucre existents en la bibliografia especialitzada, i que han tingut un inexistent ressò pràctic. Això pot ser un contrasentit en un país on l’associacionisme és tan arrelat i un dels pilars socials que ens vertebren i diferencien. En el cas de la música per a cobla, especialment destacable en un moment molt important i crític per estar en un temps de transició social molt fort. També, cal destacar vivament que té una sèrie de valors afegits de qualitat i complexitat que la situen en un interessant camí entre la cultura popular i les propostes de caràcter més comercial, en unes condicions actuals de gran desconeixement social. Les vinculacions entre estratègia, innovació, responsabilitat social i cultura del coneixement, donen a aquest treball un fort caràcter actual i adaptat a la realitat en les consideracions sobre el management en general.

Psychophysiological activation during preparation, performance, and recovery in high- and low-anxious music students

The present study provides a comprehensive view of (a) the time dynamics of the psychophysiological responding in performing music students (n = 66) before, during, and after a private and a public performance and (b) the moderating effect of music performance anxiety (MPA). Heart rate (HR), minute ventilation (VE), and all affective and somatic self-report variables increased in the public session compared to the private session. Furthermore, the activation of all variables was stronger during the performances than before or after. Differences between phases were larger in the public than in the private session for HR, VE, total breath duration, anxiety, and trembling. Furthermore, while higher MPA scores were associated with higher scores and with larger changes between sessions and phases for self-reports, this association was less coherent for physiological variables. Finally, self-reported intra-individual performance improvements or deteriorations were not associated with MPA. This study makes a novel contribution by showing how the presence of an audience influences low- and high-anxious musicians' psychophysiological responding before, during and after performing. Overall, the findings are more consistent with models of anxiety that emphasize the importance of cognitive rather than physiological factors in MPA.

Reading films through political classics : genres of politics in popular cultures

Abstract: Readin films through political classics

Artes de musicar e de improvisar na cultura popular

O artigo explora bases de sustentabilidade do valor patrimonial das chamadas culturas marginais, tomando como referente empírico as artes de musicar e de improvisar. aos preconceitos que associam a cultura popular à frivolidade se contrapõem evidências da sua criatividade. para isso, comparam-se tendências e influências musicais de um e outro lado do atlântico (portugal e brasil), na base de uma matriz partilhada de repentes e improvisações. os exemplos do fado e do samba são usados para ilustrar as variações simbólicas, no decurso do tempo, das produções culturais: dos antros de marginalidade podem emergir ícones de nacionalidade. em seguida, em um estudo de caso envolvendo jovens portugueses afrodescendentes, sem motivação extrínseca ou intrínseca para as aprendizagens do ensino formal, mostram-se reais possibilidades de emancipação através da música e da dança. finalmente, equaciona-se a possibilidade de a educação, dada a sua aposta no conhecimento, poder constituir uma importante plataforma de reconhecimento do valor patrimonial das culturas populares.

Performance anxiety : cardiorespiratory activity in high- and low-anxious professional music students in a performance situation

Questionnaire studies indicate that high-anxious musicians may suffer from hyperventilation symptoms before and/or during performance. Reported symptoms include amongst others shortness of breath, fast or deep breathing, dizziness and thumping heart. A self-report study by Widmer, Conway, Cohen and Davies (1997) shows that up to seventy percent of the tested highly anxious musicians are hyperventilators during performance. However, no study has yet tested if these self-reported symptoms reflect actual cardiorespiratory changes just before and during performance. Disturbances in breathing patterns and hyperventilation may negatively affect the performance quality in stressful performance situations. The main goal of this study is to determine if music performance anxiety is manifest physiologically in specific correlates of cardiorespiratory activity. We studied 74 professional music students of Swiss Music Universities divided into two groups (high- and lowanxious) based on their self-reported performance anxiety (State-Trait Anxiety Inventory by Spielberger). The students were tested in three distinct situations: baseline, performance without audience, performance with audience. We measured a) breathing patterns, end-tidal carbon dioxide, which is a good non-invasive estimator for hyperventilation, and cardiac activation and b) self-perceived emotions and self-perceived physiological activation. Analyses of heart rate, respiratory rate, self-perceived palpitations, self-perceived shortness of breath and self-perceived anxiety for the 15 most and the 15 least anxious musicians show that high-anxious and low-anxious music students have a comparable physiological activation during the different measurement periods. However, highanxious music students feel significantly more anxious and perceive significantly stronger palpitations and significantly stronger shortness of breath just before and during a public performance. The results indicate that low- and high-anxious music students a) do not differ in the considered physiological responses and b) differ in the considered self-perceived physiological symptoms and the selfreported anxiety before and/or during a public performance.

El conte popular català com a eina de transmissió dels valors educatius

Al final dels anys setanta neix una nova manera d'explicar contes, a partir de contistes sovint urbans i cultes, utilitzant recursos no directament tradicionals, i amb una relació amb l'auditori que s'apropa més aviat a l'espectacle instituït que no pas a la transmissió de coneixements i fantasies deis nostres avantpassats. Es configura una etapa caracteritzada per l'arraconament i l'oblit del conte popular catala; paral-lelament van desenvolupant-se noves técniques que proporcionen educació i basicament distracció als nens i nenes.

Monitoramento ambiental e fontes de informação para a tomada de decisão estratégica: o caso dos varejos formais instalados nas imediações do shopping popular Oiapoque em Belo Horizonte

Apresenta os resultados de uma pesquisa exploratória realizada no primeiro semestre de 2008 com micro e pequenos empresários instalados nas imediações do Shopping Popular Oiapoque, em Belo Horizonte. Para a consecução do objetivo central, que partiu da necessidade de descrever o comportamento informacional de tais empresários na tomada de decisão estratégica, optou-se pela aplicação de um questionário estruturado, com perguntas fechadas, a oito empresários da região, os quais foram escolhidos intencionalmente. Os resultados revelaram que os decisores estratégicos têm alta dependência com relação às fontes de informação "consumidores que compram no Oiapoque, fornecedores e funcionários da própria empresa e os concorrentes que atuam dentro do Shopping Popular" na tomada de decisão. Por outro lado, as fontes escritas como o jornal do bairro, relatórios setoriais publicados por entidades do comércio e os comércios não-concorrentes e seus respectivos funcionários e fornecedores não apresentaram resultados significativos em termos de dependência para a tomada de decisão estratégica.
