Planificación de la docencia en la implantación de materias en lengua extranjera: una experiencia pràctica

EL presente trabajo se centra en la enseñanza en inglés de una asignatura a los alumnos del Grado en Administración y Dirección de Empresas. Estos estudios son eminentemente prácticos y tienen por objeto formar profesionales capaces de dirigir y gestionar modernas organizaciones en entornos cambiantes. La selección de contenidos para la enseñanza en inglés de finanzas no puede hacerse de forma arbitraria, sino mediante el establecimiento de unos criterios que permitan configurar un corpus con el que conseguir los resultados que se pretenden, de acuerdo con los objetivos pedagógicos establecidos por el profesor y los intereses de los estudiantes. Para el diseño de la asignatura Financial Operations se llevó a cabo una adaptación tanto de la metodología pedagógica como de los contenidos con el fin de alcanzar el objetivo perseguido (adquirir una formación básica sobre el mundo de las finanzas) al mismo tiempo que adquirir unas competencias en el uso de un inglés para fines específicos, en este caso, el inglés financiero

Los Mitos de la Feminidad: su reflejo en "Las Vendas" de Raúl Pérez Torres, "Tren Nocturno" de Abdón Ubidia, "El Hombre de la Mirada Oblicua" de Javier Vásconez, "El Apátrida" de Vladimiro Rivas lturralde y "Recordando el Mar" de Francisco Proaño Arandi

Los años 70 y 80 fueron una época de renovación y revaluación de la forma y el fondo de la literatura ecuatoriana. Me pareció significativo que en una época de búsqueda de identidad y de vanguardia en la literatura la mujer haya sido representada por los escritores como un ser plano y unidimensional. cubierta por una gruesa capa de silencio. A pesar de que existen numerosos estudios sobre el período en cuestión y sobre los autores y textos escogidos ("Las Vendas" de Raúl Pérez Torres, "Tren Nocturno" de Abdón Ubidia. "El Hombre de la Mirada Oblicua" de Javier Vásconez. "El Apátrida" de Vladimiro Rivas Iturralde y "Recordm1do el Mar de Francisco Proaño Arandi), ninguno ponía especial énfasis en el rol que desempeñan las mujeres dentro de esos relatos. Me pareció una tarea descuidada y necesaria. Ya en 1975 Michael H. Handelsman señalaba en Amazonas y Artistas que faltan estudios sobre "la imagen de la mujer en las obras de los escritores". Me pareció que la teoría feminista era la más adecuada para llevar adelante este análisis pues ésta busca demostrar que la literatura y el lenguaje tienen relevancia en la creación de la sociedad y considera que el género es una construcción social. Dentro del análisis he puesto especial énfasis en el (a) rol del lector en ese constante flujo de información que se forma entre el texto, el autor y el lector: y (b) la importancia de la ideología en la construcción del sujeto y la contribución de los aparatos ideológicos del estado en la formación de éste.

La imaginación, lo fantástico y la ética en El hombre de las ruinas... (1869), de Francisco Javier Salazar Arboleda (Dossier: La novela ecuatoriana del siglo XIX)

Esta novela corta de Salazar Arboleda pertenece al Realismo en transición hacia el Naturalismo, pero, a la vez, enlaza tanto con la novela gótica inglesa del siglo XVIII, como con el cuento fantástico prevalente en la primera mitad del siglo XIX en Francia y Alemania. El cambio de tipos narrativos dentro de la historia que se relata: novela histórica-novela psicológica- novela fantástica-novela ética muestra la forma en que las literaturas europeas eran asimiladas, adaptadas e innovadas durante el siglo XIX en la narrativa ecuatoriana, pero también la manera en que la novela era un vehículo de difusión ideológica.

Dietary fat modifications and blood pressure in subjects with the metabolic syndrome in the LIPGENE dietary intervention study

Hypertension is a key feature of the metabolic syndrome. Lifestyle and dietary changes may affect blood pressure (BP), but the knowledge of the effects of dietary fat modification in subjects with the metabolic syndrome is limited. The objective of the present study was to investigate the effect of an isoenergetic change in the quantity and quality of dietary fat on BP in subjects with the metabolic syndrome. In a 12-week European multi-centre, parallel, randomised controlled dietary intervention trial (LIPGENE), 486 subjects were assigned to one of the four diets distinct in fat quantity and quality: two high-fat diets rich in saturated fat or monounsaturated fat and two low-fat, high-complex carbohydrate diets with or without 1·2 g/d of very long-chain n-3 PUFA supplementation. There were no overall differences in systolic BP (SBP), diastolic BP or pulse pressure (PP) between the dietary groups after the intervention. The high-fat diet rich in saturated fat had minor unfavourable effects on SBP and PP in males.

The leptin receptor Gln223Arg polymorphism (rs1137101) mediates the postprandial lipaemic response, but only in males.

Objective: An exaggerated postprandial triacylglycerol (TAG) response is an important determinant of cardiovascular disease risk. With increased recognition of the role of leptin in systemic macronutrient metabolism, we used a candidate gene approach to examine the impact of the common leptin receptor (LEPR) Gln223Arg polymorphism (rs1137101) on postprandial lipaemia. Methods and results: Healthy adults (n ¼ 251) underwent a sequential meal postprandial investigation, in which blood samples were taken at regular intervals after a test breakfast (t ¼ 0) and lunch (t ¼ 330 min). Fasting total- and low-density lipoprotein cholesterol were 9% lower in the ArgArg than GlnArg group (P < 0.04), whereas fasting TAG was 27% lower in the ArgArg than GlnGln group (P < 0.02). The magnitude of the postprandial TAG response was also significantly lower in the ArgArg compared with the GlnArg and GlnGln genotypes, with a 26% lower area under the curve (AUC) and incremental AUC in the ArgArg individuals (P � 0.023). Genotype*gender interactions were evident for fasting and postprandial TAG responses (P < 0.05), with the genotype effect only evident in males. Regression analysis indicated that the LEPR genotype and genotype*gender interactions were independent predictors of the TAG AUC, accounting for 6.3% of the variance. Our main findings were replicated in the independent LIPGENE-Cordoba postprandial cohort of metabolic syndrome subjects (n ¼ 75), with a 52% lower TAG AUC in the ArgArg than GlnGln male subjects (P ¼ 0.018). Conclusion: We report for the first time that the common LEPR Gln223Arg genotype is an important predictor of postprandial TAG in males. The mechanistic basis of these associations remains to be determined.

Top single nucleotide polymorphisms affecting carbohydrate metabolism in Metabolic Syndrome: from the LIPGENE study

Rationale:Metabolic Syndrome (MetS) is a high prevalence condition characterized by altered energy metabolism, insulin resistance and elevated cardiovascular risk.Objectives:Although many individual single nucleotide polymorphisms (SNPs) have been linked to certain MetS features, there are few studies analyzing the influence of SNPs on carbohydrate metabolism in MetS.Methods:904 SNPs (tag SNPs and functional SNPs) were tested for influence in eight fasting and dynamic markers of carbohydrate metabolism, performing an intravenous glucose tolerance test in 450 participants of the LIPGENE study.Findings:From 382 initial gene-phenotype associations between SNPs and any phenotypic variables, 61 (a 16 % of the pre-selected) remained significant after Bootstrapping. Top SNPs affecting glucose metabolism variables were as follows: fasting glucose: rs26125 (PPARGC1B); fasting insulin: rs4759277 (LRP1); C peptide: rs4759277 (LRP1); HOMA-IR: rs4759277 (LRP1); QUICKI: rs184003 (AGER); SI: rs7301876 (ABCC9), AIRg: rs290481 (TCF7L2) and DI: rs12691 (CEBPA).Conclusions:We describe here the top SNPs linked to phenotypic features in carbohydrate metabolism among aproximately 1000 candidate gene variations in fasting and postprandial samples of 450 patients with MetS from the LIPGENE study.

Diphenyllead(IV) thiosemicarbazonates and pyrazolonates: Synthesis and characterization

Cyclization of thiosemicarbazones derived from beta-keto esters and beta-keto amides (HTSC) in the presence of diphenyllead(IV) acetate was explored in methanol solution at room temperature and under reflux. All beta-keto ester TSCs underwent cyclization to give the corresponding pyrazolone (HL), which, except in one case, deprotonated and coordinated the PbPh(2)(2+) moiety to form homoleptic [PbPh(2)(L)(2)] or heteroleptic [PbPh(2)(OAc)(L)] derivatives. Cyclization did not occur with beta-keto amide TSCs and only [Pbph(2)(TSC)(2)] or [PbPh(2)(OAc)(TSC)] thiosernicarbazonates were isolated. The complexes were characterized by IR spectroscopy in the solid state and by (1)H, (13)C and (207)Pb NMR spectroscopy in DMSO-d(G) solution, in which they evolve and decompose with time. Additionally, crystals of p-acetoacetanisidide thiosemicarbazone (HTSC(10)), [PbPh(2)(OAc)(L(5))] center dot MeOH (HL(5) = 2,5-dihydro-3,4-dimethyl-5-oxo-1H-pyrazolone-1-carbothioamide), [PbPh(2)Cl(L(2))] (HL(2) = 2,5-dihydro-5-oxo-3-phenyl-1H-pyrazolone-1-carbothioamide), [PbPh(2)(OAc)(TSC(8))]center dot 2MeOH (HTSC(8) = acetoacetanilide thiosemicarbazone), [PbPh(2)(OAc)(TSC(10))]center dot H(2)O and [PbPh(2)(OAc)(TSC(11))] center dot 0.75MeOH (HTSO(11) = o-acetoacetotoluidide) were studied by X-ray crystallography. The complexes, monomers or dimers with almost linear C-Pb-C moieties, are compared with the corresponding derivatives of Pb(II). (C) 2009 Elsevier Ltd. All rights reserved.

Synthesis and Crystal Structures of Octahedral Sn(IV) Complexes Prepared from SnCl(2)center dot 2H(2)O and 2-Hydroxyacetophenone (S-benzydithiocarbazate) Ligand (H(2)L)

Two coordination octahedral Sn(IV) complexes [Sn(L)(2)] and cis-[SnCl(2)(L)(dmso)], where H(2)L is 2-hydroxyacetophenone (S-benzydithiocarbazate), were prepared and characterized by elemental analysis, IR, NMR ((1)H, (13)C), (119)Sn Mossbauer spectroscopies and X-ray diffraction techniques to investigate their structural properties. Both crystallize in the Monoclinic system, with parameters: a = 8.1905(3), b = 30.8811(15), c = 12.8959(7) angstrom, beta = 94.465(3)degrees and Z = 4 for [Sn(L)(2)] and a = 8.5247(2), b = 21.5445(7), c = 12.3706(3) angstrom, beta = 96.932(2)degrees and Z = 4 for cis-[SnCl(2)(L)(dmso)]. In both complexes, the Sn(IV) central atom is coordinated in a distorted octahedral geometry with the thiolate ligand (L(2-)) coordinated via O, N and S atoms. The (119)Sn Mossbauer spectroscopy of the complexes were studied and the results revealed that both complexes posses isomer shift (delta) and quadrupole splitting (Delta), which are almost the same.

Lead(II)-induced formation and coordination of 3,4-dihydro-3-thioxo-1,2,4-triazin-5(2H)-one

Cyclization of (n)butyl glyoxylate thiosemicarbazone (HBuTSC) under reflux in the presence of Pb(OAc)(2) led to tile formation of the complex [Pb(HTz)(2)] (H(2)Tz = 3,4-dihydro-3-thioxo-1,2,4-triazin-5(2H)-one), which after recrystallization from DMSO afforded the polymer [Pb(Tz)](n), the first example of a Tz(2-) metal complex.

Dimethylthallium(III) complexes with picolinic acid and its hydroxyl derivatives

The reaction of dimethylthallium(III) hydroxide with picolinic acid (Hpic), 3-hydroxypicolinic acid (H(2)3hpic) and 6-hydroxypicolinic acid (H(2)6hpic) in an aqueous/methanol mixture afforded the complexes [TlMe(2)(pic)] (1), [TlMe(2)(H3hpic)] (2) and [TlMe(2)(H6hpic)] (3), respectively. Complex 3`, [NaTlMe(2)(6hpic)(2)](n), was obtained as a minor product from a methanolic solution of 3. Compounds 1-3 were characterized by IR and Raman spectroscopy and, in the cases of 1, 2 and Y, by single-crystal X-ray diffraction. Complex 3` is the first example of an H6hpic(-) heterobimetallic compound to be isolated. The (1)H and (13)C NMR spectra of 1 and 2 are also discussed. (c) 2008 Elsevier Ltd. All rights reserved.
