Hedwig and The Angry Inch: el Plató més alternatiu

L'objectiu d'aquest article és mostrar com un mite antic, el mite dels tres gèneres, també anomenat de l'androgin de l'Aristòfanes del Simposi de Plató, esdevé per a John Cameron Mitchell la imatge adient per a explicar l'especial personalitat d'un home, Hedwig, que esdevé mitjançant una operació un androgin imperfecte, però que simbolitza la possibilitat d'una humanitat unida o l'acostament de móns diferents, de la mateixa manera que ell va pertànyer a les dues Berlín dividides per un mur que ara ja ha caigut, quedant restablerta així la unitat perduda.

Miguel de Unamuno i Heràclit: de ‘La elegía eterna’ a ‘La flor tronchada’

[cat] L’objectiu d’aquest breu article és provar i analitzar la influència de la saviesa d’Heràclit en alguns poemes de Miguel de Unamuno com ara ‘La elegía eterna’ i ‘La flor tronchada’. En certes ocasions –‘La elegía eterna’- Heràclit és per a ell una mena de crossa amb l’ajut de la qual reïx a mostrar poèticament les seves angoixes i, en d’altres –‘La flor tronchada’- necessita realment Heràclit per a il•lustrar la seva visió de Déu i de la vida humana com una lluita o guerra permanent.

CHARACTERIZATION OF HEADWATERS PEATS OF THE RIO ARAÇUAÍ, MINAS GERAIS STATE, BRAZIL

Peatlands are soil environments that accumulate water and organic carbon and function as records of paleo-environmental changes. The variability in the composition of organic matter is reflected in their morphological, physical, and chemical properties. The aim of this study was to characterize these properties in peatlands from the headwaters of the Rio Araçuaí (Araçuaí River) in different stages of preservation. Two cores from peatlands with different vegetation types (moist grassland and semideciduous seasonal forest) from the Rio Preto [Preto River] headwaters (conservation area) and the Córrego Cachoeira dos Borges [Cachoeira dos Borges stream] (disturbed area) were sampled. Both are tributaries of the Rio Araçuaí. Samples were taken from layers of 15 cm, and morphological, physical, and chemical analyses were performed. The 14C age and δ13C values were determined in three samples from each core and the vertical growth and organic carbon accumulation rates were estimated. Dendrograms were constructed for each peatland by hierarchical clustering of similar layers with data from 34 parameters. The headwater peatlands of the Rio Araçuaí have a predominance of organic material in an advanced stage of decomposition and their soils are classified as Typic Haplosaprists. The organic matter in the Histosols of the peatlands of the headwaters of the Rio Araçuaí shows marked differences with respect to its morphological, physical, and chemical composition, as it is influenced by the type of vegetation that colonizes it. The peat from the headwaters of the Córrego Cachoeira dos Borges is in a more advanced stage of degradation than the peat from the Rio Preto, which highlights the urgent need for protection of these ecosystems/soil environments.

Atributos Físicos de um Cambissolo Cultivado e Tratado com Biofertilizante na Chapada do Apodi, Ceará

O conhecimento sobre as alterações físicas e qualidade do solo é importante para o direcionamento adequado das estratégias de manejo a serem utilizadas quando da exploração do solo por cultivos agrícolas. Este trabalho teve como objetivo avaliar os efeitos do cultivo e da aplicação de um biofertilizante, obtido a partir de esterco bovino, sobre a qualidade física de um Cambissolo cultivado com Ficus carica L., irrigado por sistema de gotejamento. Para fins de avaliação da qualidade física, foram contempladas cinco situações de solo: sob cultivo de figo sem aplicação do biofertilizante (testemunha); com aplicação de 20, 40 e 60 % do biofertilizante na lâmina de irrigação; e mata nativa secundária (testemunha adicional), até a profundidade de 0,3 m, nas camadas de 0,0-0,1, 0,1-0,2; e 0,2-0,3 m, com quatro repetições. Nessas camadas, foram coletadas amostras de solo com estrutura deformada e indeformada para realizar análises físicas, como granulometria, argila dispersa em água, carbono orgânico, densidade das partículas e do solo, resistência do solo à penetração e curva característica de água no solo. O cultivo do solo nas condições descritas nesta pesquisa, como preparo do solo por aração e gradagem, uso de irrigação e todos os tratos culturais necessários à condução da cultura de figo, não piora a qualidade física do solo em nenhuma das camadas avaliadas. A aplicação de biofertilizante melhora a qualidade física do solo, particularmente no tocante à retenção de água em decorrência do aumento da microporosidade.

En torno a los efectos de la edad en el aprendizaje escolar de una lengua extrangera

The purpose of this article is to treat a currently much debated issue, the effects of age on second language learning. To do so, we contrast data collected by our research team from over one thousand seven hundred young and adult learners with four popular beliefs or generalizations, which, while deeply rooted in this society, are not always corroborated by our data.Two of these generalizations about Second Language Acquisition (languages spoken in the social context) seem to be widely accepted: a) older children, adolescents and adults are quicker and more efficient at the first stages of learning than are younger learners; b) in a natural context children with an early start are more liable to attain higher levels of proficiency. However, in the context of Foreign Language Acquisition, the context in which we collect the data, this second generalization is difficult to verify due to the low number of instructional hours (a maximum of some 800 hours) and the lower levels of language exposure time provided. The design of our research project has allowed us to study differences observed with respect to the age of onset (ranging from 2 to 18+), but in this article we focus on students who began English instruction at the age of 8 (LOGSE Educational System) and those who began at the age of 11 (EGB). We have collected data from both groups after a period of 200 (Time 1) and 416 instructional hours (Time 2), and we are currently collecting data after a period of 726 instructional hours (Time 3). We have designed and administered a variety of tests: tests on English production and reception, both oral and written, and within both academic and communicative oriented approaches, on the learners' L1 (Spanish and Catalan), as well as a questionnaire eliciting personal and sociolinguistic information. The questions we address and the relevant empirical evidence are as follows: 1. "For young children, learning languages is a game. They enjoy it more than adults."Our data demonstrate that the situation is not quite so. Firstly, both at the levels of Primary and Secondary education (ranging from 70.5% in 11-year-olds to 89% in 14-year-olds) students have a positive attitude towards learning English. Secondly, there is a difference between the two groups with respect to the factors they cite as responsible for their motivation to learn English: the younger students cite intrinsic factors, such as the games they play, the methodology used and the teacher, whereas the older students cite extrinsic factors, such as the role of their knowledge of English in the achievement of their future professional goals. 2 ."Young children have more resources to learn languages." Here our data suggest just the opposite. The ability to employ learning strategies (actions or steps used) increases with age. Older learners' strategies are more varied and cognitively more complex. In contrast, younger learners depend more on their interlocutor and external resources and therefore have a lower level of autonomy in their learning. 3. "Young children don't talk much but understand a lot"This third generalization does seem to be confirmed, at least to a certain extent, by our data in relation to the analysis of differences due to the age factor and productive use of the target language. As seen above, the comparably slower progress of the younger learners is confirmed. Our analysis of interpersonal receptive abilities demonstrates as well the advantage of the older learners. Nevertheless, with respect to passive receptive activities (for example, simple recognition of words or sentences) no great differences are observed. Statistical analyses suggest that in this test, in contrast to the others analyzed, the dominance of the subjects' L1s (reflecting a cognitive capacity that grows with age) has no significant influence on the learning process. 4. "The sooner they begin, the better their results will be in written language"This is not either completely confirmed in our research. First of all, we perceive that certain compensatory strategies disappear only with age, but not with the number of instructional hours. Secondly, given an identical number of instructional hours, the older subjects obtain better results. With respect to our analysis of data from subjects of the same age (12 years old) but with a different number of instructional hours (200 and 416 respectively, as they began at the ages of 11 and 8), we observe that those who began earlier excel only in the area of lexical fluency. In conclusion, the superior rate of older learners appears to be due to their higher level of cognitive development, a factor which allows them to benefit more from formal or explicit instruction in the school context. Younger learners, however, do not benefit from the quantity and quality of linguistic exposure typical of a natural acquisition context in which they would be allowed to make use of implicit learning abilities. It seems clear, then, that the initiative in this country to begin foreign language instruction earlier will have positive effects only if it occurs in combination with either higher levels of exposure time to the foreign language, or, alternatively, with its use as the language of instruction in other areas of the curriculum.

Gender and family firms: an interdisciplinary approach

This study contributes to developing our understanding of gender and family business, a topic so crucial to recent policies about competitive growth. It does so by providing an interdisciplinary synthesis of some major theoretical debates. It also contributes to this understanding by illuminating the role of women and their participation in the practices of the family and the business. Finally, it explores gender relations and the notion that leadership in family business may take complex forms crafted within constantly changing relationships. Leadership is introduced as a concept that captures the reality of women and men in family firms in a better way than other concepts used by historians or economists like ownership and management.

The determinants of industrial location in Spain, 1856-1929

Durant el segle XIX, l'economia espanyola va transitar per les primeres etapes de la industrialització. Aquest procés es va donar en paral·lel a la integració del mercat domèstic de béns i factors, en un moment en què les reformes liberals i la construcció de la xarxa ferroviària, entre d'altres, van generar una important caiguda en els costos detransport. Al mateix temps que es donava aquesta progressiva integració del mercat domèstic espanyol, es van produir canvis significatius en la pauta de localització industrial. D'una banda, hi hagué un augment considerable de la concentració espacial de la indústria des de mitjans de segle XIX i fins a la Guerra Civil, i d¿altra, un increment de l'especialització regional. Ara bé, quines van ser les forces que van generar aquests canvis? Des d¿un punt de vista teòric, el model de Heckscher-Ohlin suggereix que la distribució a l'espai de l¿activitat econòmica ve determinada per l'avantatge comparativa dels territoris en funció de la dotació relativa de factors. Al seu torn, els models de Nova Geografia Econòmica (NEG) mostren l'existència d'una relació en forma de campana entre el procés d'integració econòmica i el grau de concentració geogràfica de l'activitat industrial. Aquest article examina empíricament els determinants de la localització industrial a Espanya entre 1856 i 1929, mitjançant l'estimació d¿un model que combina els elements de tipus Heckscher-Ohlin i els factors apuntats des de la NEG, amb l'objectiu de contrastar la força relativa dels arguments vinculats a aquestes dues interpretacions a l'hora de modular la localització de la indústria a Espanya. L'anàlisi dels resultats obtinguts mostra que tant la dotació de factors com els mecanismes de tipus NEG van ser elements determinants que expliquen la distribució geogràfica de la indústria des del segle XIX, tot i que la seva força relativa va anar variant amb el temps.

Were Spanish migrants attracted by industrial agglomerations?: an analysis for the interwar years in the light of the new economic geography

In this paper we examine whether access to markets had a significant influence onmigration choices of Spanish internal migrants in the inter-war years. We perform astructural contrast of a New Economic Geography model that focus on the forwardlinkage that links workers location choice with the geography of industrial production,one of the centripetal forces that drive agglomeration in the NEG models. The resultshighlight the presence of this forward linkage in the Spanish economy of the inter-warperiod. That is, we prove the existence of a direct relation between workers¿ localizationdecisions and the market potential of the host regions. In addition, the direct estimationof the values associated with key parameters in the NEG model allows us to simulatethe migratory flows derived from different scenarios of the relative size of regions andthe distances between them. We show that in Spain the power of attraction of theagglomerations grew as they increased in size, but the high elasticity estimated for themigration costs reduced the intensity of the migratory flows. This could help to explainthe apparently low intensity of internal migrations in Spain until its upsurge during the1920s. This also explains the geography of migrations in Spain during this period,which hardly affected the regions furthest from the large industrial agglomerations (i.e.,regions such as Andalusia, Estremadura and Castile-La Mancha) but had an intenseeffect on the provinces nearest to the principal centres of industrial development.

Aportacions a la història de la psicopatologia infantil

Com ja van fer anteriorment amb la Història de la psiquiatria, en aquest treball el Seminari Pere Mata publica un recull d'articles fins ara dispersos aquest cop centrats en la psicopatologia infantil.Els setze articles es poden distribuir en tres grups. El primer, el formen articles sobre la història de l'especialitat. Un segon grup gira entorn de la influència de la psiquiatria infantil francesa. L'últim i més nombròs tracta del passat de la psiquiatria infantil espanyola i catalana.

Nomina academicorum: 1770-1995

La publicació d'aquesta nòmina coincideix amb el 225è aniversari de la creació de la "Academia Médico Práctica de Barcelona", després anomenada Reial Acadèmia de Medicina de Catalunya. El llibre no pretén ser una història de l'Acadèmia si no que es limita a llistar els gairebé 350 membres numeraris de l'acadèmia. Ara bé, per fer-ho menys feixuc, s'han afegit breus referències sobre l'evolució, la composició i els locals on s'ha desenvolupat la seva activitat.
