Irakurriaren ulermenaren zailtasunak bigarren hezkuntzan

(FR)Ce texte reprend la question de la compréhension de lecture et la faible note que nos étudiants du secondaire donnent à ce secteur, d’après PISA. De plus en plus de voix s’élèvent pour réclamer que la compréhension de lecture soit une des tâches de tous les professeurs et plus seulement des professeurs de langue et littérature. Lors de la préparation au métier d’enseignant, de plus en plus de cours sont organisés en rapport avec cette question de plus en plus préoccupante dans ce secteur. Les données sont celles-ci et toutes les tentatives pour résoudre ce problème semblent insuffisantes si on ne reprend pas la question au niveau du Curriculum et si on prépare les professeurs aux stratégies de lecture pour que les élèves parviennent à être des lecteurs compétents.

Análisis de la flexibilidad de la oferta de formación en gestión del País Vasco

El contenido de este trabajo deriva del proyecto de investigación UE-1998-23, «Oferta y Demanda de Formación en Gestión Empresarial para Directivos en la CAPV» y del contrato de investigación «Análisis de la Oferta de Formación en Gestión y en Gestión del Conocimiento». El proyecto era perteneciente a la convocatoria de 1998 de ayudas del Gobierno Vasco a Proyectos de Investigación e Innovacion Tecnológica entre Universidades y Empresas, en su elaboración y desarrollo participaron la Universidad del País Vasco-Euskal Herriko Unibertsitatea, la Universidad de Deusto (ESTE) y el Cluster del Conocimiento, como empresa.

Survey of the fatty acid composition of Canadian beef: Backfat and longissimus lumborum muscle

[EN]A survey of Canadian retail beef was undertaken with emphasis on the trans fatty acid (TFA) and conjugated linoleic acid (CLA) isomers, and compared with current health recommendations. Thirty striploin steaks were collected in the winter and summer from major grocery stores in Calgary (Alberta, Canada). Steak fatty acid compositions (backfat and longissimus lumborum muscle analysed separately) showed minor seasonal differences with lower total saturates (PB0.05) and higher total monounsaturates (PB 0.01) in winter, but no differences in total polyunsaturated fatty acids. The ratio of n-6 and n-3 polyunsaturated fatty acid in longissimus lumborum averaged 5.8. The average TFA content in longissimus lumborum was 0.128 g 100 g_1 serving size, and 10t-18:1 was found to be the predominant isomer (32% of total trans), while vaccenic acid was second most abundant (15% of total trans). The CLA content in longissimus lumborum was similar to that of backfat, ranging from 0.43 to 0.60% of total fatty acids and rumenic acid represented 60% of total isomers. Overall, there is still room for improvement in the saturated, mono- and polyunsaturated fatty acid composition of Canadian beef to meet general dietary guidelines for human consumption and additional targets should include reducing 10t-18:1 while increasing both rumenic and vaccenic acids.

Evaluation of wheat or corn dried distillers' grains with solubles on performance and carcass characteristics of feedlot steers

[EN]A study was conducted on crossbred steers (n=275; 376±924 kg) to evaluate performance and carcass quality of cattle fed wheat or corn dried distillers’ grains with solubles (DDGS). The control ration contained 86.6% rolled barley grain, 5.7% supplement and 7.7% barley silage (DM basis). The four treatments included replacement of barley grain at 20 or 40% of the diet (DM basis) with wheat or corn DDGS. Steers were slaughtered at a common end weight of 645 kg with 100 steers randomly (n=20 per treatment) selected for determination of the retail yield of sub-primal boneless boxed beef (SPBBB). Data were analyzed as a completely randomized design using pen as the experimental unit. Feeding increasing levels of wheat DDGS led to a quadratic increase in dry matter intake (DMI) (P<0.01), whereas increasing levels of corn DDGS led to a quadratic decrease in DMI (P=0.01). Average daily gain was not influenced (P=0.13) by feeding wheat or corn DDGS, but cattle fed corn DDGS exhibited a quadratic increase (P=0.01) in gain:feed. As a result, a quadratic increase (P<0.01) in calculated NEg of the diet was observed as corn DDGS levels increased. A linear decrease (P=0.04) in days on feed (169, 166 and 154 d) was noted when increasing levels of wheat DDGS (0, 20 and 40%) were fed. Dressing percentage increased in a linear fashion with wheat DDGS (P<0.01) inclusion level and in a quadratic fashion (P=0.01) as corn DDGS inclusion level increased although other carcass traits were not affected (P=0.10) by treatment. The results indicate that replacement of barley grain with corn or wheat DDGS up to 40% of the diet (DM) can lead to superior performance (improved gain:feed or reduced days on feed, respectively) with no detrimental effect on quality grade or carcass SPBBB yield.

[EN]Traditionally writing skills have been given priority in language teaching and so, oral skills have been put aside. However, during the last years many voices have asserted the importance of oral skills. Therefore, they claim that oral language teaching must be emphasized at school. Also, the necessity of strengthening oral language is shown in the new curriculum. Nevertheless, those intentions are reflected in very different ways in textbooks. In this work we have looked into the treatment that oral language is given in teaching materials because, in our opinion, textbooks are one of the most important tools for teachers. The facts show that the importance given to oral language and the exercises and tools needed to work that skill are very different from one publishing house to another. Besides, we have confirmed that all the textbooks don’t satisfy the requirements proposed in the Basque official curriculum (e.g. didactic sequences) or that the approach to the text or the way to work with it are not always what they should be. Therefore, it is obvious that we have still a long way in the field of oral language and specially in the way of teaching oral skills
