Introducción de elementos de Economía en el currículum de 12 a 16 años.

Introducir en el currículum escolar de 12 a 16 años una serie de conceptos básicos de Economía, que traten de subsanar las deficiencias que tienen en este campo, los alumnos de estos niveles educativos (ciclo superior de EGB y primeros cursos de EEMM o bien el primer y segundo ciclo de Educación Secundaria Obligatoria). Fomentar en ellos una actitud crítica y hábitos de participación, motivándoles e interesándoles en los problemas socioeconómicos que tiene la sociedad en la que viven. 2 grupos de octavo de EGB del Colegio Público Antonio Gaudí de Cornellà. Las fases del proceso de elaboración fueron: a) selección de conceptos básicos a programar; b) organización y estructuración de éstos en dos grandes bloques temáticos: 1. la Economía, un juego de varios peones, 2. el dinero y las entidades financieras, ambos desglosados en unidades temáticas. En la aplicación de la experiencia se le da un tratamiento interdisciplinar desarrollándose dos programas diferentes: uno dirigido al profesor presentándose su programación en dos tipos de fichas, una general de cada uno de los bloques temáticos y otra específica de cada una de las unidades temáticas. El otro, dirigido al alumno, comprendiendo en su programación el desarrollo de cada una de las unidades temáticas, pasándoles una prueba inicial anterior a su desarrollo y otra posterior a él. Los conceptos tratados interesaban a los alumnos, la forma de presentarlos resultaba adecuada por su correcta comprensión y estos mostraban un gran interés por estos temas que los veían muy ligados con la vida real. Los resultados confirman un aumento moderado en la asimilación de los conceptos (se pasa del 67,5 al 85 por ciento) pero no fueron tan óptimos como cabía esperar. Las causas posiblemente fueron debidas a que no se dispuso de tiempo suficiente para desarrollar los diferentes aspectos. Esta experiencia podía ser integrada perfectamente en el actual currículum de las Enseñanzas Medias y, en especial, en el nuevo diseño curricular de la Educación Secudaria Obligatoria.

A largely intolerable combination of two mainly unconnected texts: 1. Description of the Barefoot in the Head event, at BHQU, NY, 12/11/09; 2. Fictioning and the End

An evaluation of the 'Barefoot in the Head' performance event, I co-curated with Alun Rowlands and Mark Beasley, at Bruce High Quality Foundation University, New York, as part of Performa 09 New York, 12 November 2009 - an examination of my own performance and the other performances occurring simultaneously at the event.

In at the Deep End. Impressions of farming in a year gaining experience: 1952-3; 1978-85

The book describes a wide variety of students’ experiences in their practical year prior to entering University to study BSc Agriculture. Until comparatively recently it was the normal requirement for all such students, whether or not they already had home farming experience, to gain a full year’s experience of practical agriculture – and to write a report thereon. This record of 41 students’ reports of the pre-entry year begins with Paul’s own experience in the early 1950s before 41 reports from 30 or more years ago. The essays provide compelling and fascinating stories, well-articulated with clear acknowledgement for most part of the humanity and the warmth with which each student was treated by farmers and farm workers alike, despite the difference in both age and experience (considerable!). [This summary is an extract from the full overview which is archived here together with the book.]

Clopidogrel, independent of the vascular P2Y(12) receptor, improves arterial function in small mesenteric arteries from Angll-hypertensive rats

The P2Y(12) receptor antagonist clopidogrel blocks platelet aggregation, improves systemic endothelial nitric oxide bioavailability and has anti-inflammatory effects. Since P2Y(12) receptors have been identified in the vasculature, we hypothesized that clopidogrel ameliorates Angll (angiotensin II)-induced vascular functional changes by blockade of P2Y(12) receptors in the vasculature. Male Sprague Dawley rats were infused with Angll (60 ng/min) or vehicle for 14 days. The animals were treated with clopidogrel (10 mg . kg(-1) of body weight . day(-1)) or vehicle. Vascular reactivity was evaluated in second-order mesenteric arteries. Clopidogrel treatment did not change systolic blood pressure [(mmHg) control-vehicle, 117 +/- 7.1 versus control-clopidogrel, 125 +/- 4.2; Angll vehicle, 197 +/- 10.7 versus Angll clopidogrel, 198 +/- 5.2], but it normalized increased phenylephrine-induced vascular contractions [(%KCI) vehicle-treated, 182.2 +/- 18% versus clopidogrel, 133 +/- 14%), as well as impaired vasodilation to acetylcholine [(%) vehicle-treated, 71.7 +/- 2.2 versus clopidogrel, 85.3 +/- 2.8) in Angll-treated animals. Vascular expression of P2Y(12) receptor was determined by Western blot. Pharmacological characterization of vascular P2Y(12) was performed with the P2Y(12) agonist 2-MeS-ADP [2-(methylthio) adenosine 5`-trihydrogen diphosphate trisodium]. Although 2-MeS-ADP induced endothelium-dependent relaxation [(Emax %) = 71 +/- 12%) as well as contractile vascular responses (Emax % = 83 +/- 12%), these actions are not mediated by P2Y(12) receptor activation. 2-MeS-ADP produced similar vascular responses in control and Angll rats. These results indicate potential effects of clopidogrel, such as improvement of hypertension-related vascular functional changes that are not associated with direct actions of clopidogrel in the vasculature, supporting the concept that activated platelets contribute to endothelial dysfunction, possibly via impaired nitric oxide bioavailability.

Emprego, capital, produtividade e salarios : estimativas de suas evoluções na indústria de transformação paulista: l975/85

Trata dos problemas do emprego e da remuneração da força de trabalho industrial no Estado de São Paulo. Estabelece uma associação entre acumulação de capital, produtividade e salários reais, caracterizando o tipo do processo de capitalização adotado, e apontando deficiências no repasse dos acréscimos produtivos aos salários, na indústria de transformação paulista. Compara ocorrências pr´sticas com enunciados teóricos, utilizando estimativas obtidas a partir dos dados estatísticos pesquisados

Exigências de treonina de leitões dos 7 aos 12 e dos 12 aos 23 kg

Foram realizados dois experimentos (E) com 204 leitões Large White (E1: dos 7,23 aos 12,32 kg; e E2: dos 12,64 aos 23,81 kg). O delineamento experimental foi de blocos ao acaso com quatro níveis de treonina na ração (E1: 0,80; 0,87; 0,93 e 0,99 %; e E2: 0,69; 0,74; 0,80 e 0,85 %); oito (E1) e nove (E2) repetições para o consumo diário de ração (CDR), ganho diário de peso (GDP), ganho diário de peso ajustado (GDPA) e conversão alimentar (CA); e cinco repetições para uréia plasmática (U). Não se observaram diferenças no CDR e GDP (P>0,10). Verificaram-se efeitos quadráticos da treonina no GDPA do E1 (P=0,086) e E2 (P=0,052), na CA do E2 (P=0,035) e na U do E1 (P=0,002), bem como efeito linear negativo na CA do E1 (P=0,030) e U do E2 (P=0,044). O nível de 0,89% de treonina minimizou o teor plasmático de uréia e o de 0,94% maximizou o ganho diário de peso ajustado no E1, enquanto no E2 0,76% de treonina na ração maximizou o ganho diário de peso ajustado e minimizou a conversão alimentar.

Genetic population data of 12 STR loci of the PowerPlex (R) Y system in the state of São Paulo population (Southeast of Brazil)

Allele frequency distributions and population data for 12 Y-chromosomal short tandem repeats (STRs) included in the PowerPlex (R) Y Systems (Promega) were obtained for a sample of 200 healthy unrelated males living in S (a) over tildeo Paulo State (Southeast of Brazil). A total of 192 haplotypes were identified, of which 184 were unique and 8 were found in 2 individuals. The average gene diversity of the 12 Y-STR was 0.6746 and the haplotype diversity was 0.9996. Pairwise analysis confirmed that our population is more similar with the Italy, North Portugal and Spain, being more distant of the Japan. (c) 2007 Elsevier B.V. All rights reserved.
