Cada vez son más los estudios a nivel educativo, que serealizan sobre las enseñanzas “uniformes” que prevalecen en las escuelascontemporáneas, donde existen currículos básicos que constituyen unconjunto de hechos que todos deben conocer pero muy pocas alternativaselectivas.
Abstrahierendes Lernen durch aktive Modellbildung: Evaluation eines Prozesses und einer Lernumgebung
Resumo:
Die Fähigkeit zum Lernen durch Abstraktion aus Erfahrungen unterscheidet Experten von Novizen. Wir stellen einen Prozess für individuelles abstrahierendes Lernen und eine diesen Prozess unterstützende Lernumgebung vor. Die Ergebnisse einer Pilotstudie zeigen, dass Lernende unter Nutzung der Lernumgebung aus Fallbeispielen ein abstraktes Modell erstellen und über ihren Prozess reflektieren konnten. Dies fiel ihnen leichter, wenn die Fallbeispiele wenige gemeinsame Oberflächenmerkmale aufwiesen. Im Gegensatz zum intendierten Lernprozess wandten manche Lernende einen anderen Prozess an.

Background and Purpose-Few reliable estimates of the long-term functional outcome after stroke are available. This population-based study aimed to describe disability, dependency, and related independent prognostic factors at 5 years after,a first-ever stroke in patients in Perth, Western Australia. Methods-All individuals with a suspected acute stroke who were resident in a geographically defined region (population, 138 708) of Perth, Western Australia, were registered prospectively and assessed according to standardized diagnostic criteria over a period of 18 months in 1989 to 1990. Patients were followed up prospectively at 4 and 12 months and 5 years after the index event. Results-There were 370 cases of first-ever stroke, and 277 patients survived to 30 days. Of these early survivors, 152 (55%) were alive at 5 years, and among those who were neither institutionalized (n=146) nor disabled (n=129) at the time of their stroke, 21 (14%) were institutionalized in a nursing home, and 47 (36%) were disabled. The most important predictors of death or disability at 5 years were increasing age, baseline disability defined by a Barthel Index score of <20/20 (odds ratio [OR], 6.3; 95% confidence interval [CI], 2.7 to 14), moderate hemiparesis (OR, 2.7. 95% CI, 1.1 to 6.2), severe hemiparesis (OR, 4.5; 95% CI, 1.1 to 19), and recurrent stroke (OR, 9.4; 95% CI, 3.0 to 30). A low level of activity before the stroke was a significant predictor of institutionalization, and subsequent recurrent stroke was a consistent, independent predictor of institutionalization, disability, and death or institutionalization, increasing the odds of each of these 3 adverse outcomes by 5- to 15-fold. Conclusions-Among 30-day survivors of first-ever stroke, about half survive 5 years; of survivors, one third remain disabled, and I in 7 are in permanent institutional care. The major modifiable predictors of poor long-term outcome are a low level of activity before the stroke and subsequent recurrent stroke. Efforts to increase physical activity among the elderly and to prevent recurrent stroke in survivors of a first stroke are likely to reduce the long-term burden of cerebrovascular disease.

Electroencephalography is mandatory to determine the epilepsy syndrome. However, for the precise localization of the irritative zone in patients with focal epilepsy, costly and sometimes cumbersome imaging techniques are used. Recent small studies using electric source imaging suggest that electroencephalography itself could be used to localize the focus. However, a large prospective validation study is missing. This study presents a cohort of 152 operated patients where electric source imaging was applied as part of the pre-surgical work-up allowing a comparison with the results from other methods. Patients (n = 152) with >1 year postoperative follow-up were studied prospectively. The sensitivity and specificity of each imaging method was defined by comparing the localization of the source maximum with the resected zone and surgical outcome. Electric source imaging had a sensitivity of 84% and a specificity of 88% if the electroencephalogram was recorded with a large number of electrodes (128-256 channels) and the individual magnetic resonance image was used as head model. These values compared favourably with those of structural magnetic resonance imaging (76% sensitivity, 53% specificity), positron emission tomography (69% sensitivity, 44% specificity) and ictal/interictal single-photon emission-computed tomography (58% sensitivity, 47% specificity). The sensitivity and specificity of electric source imaging decreased to 57% and 59%, respectively, with low number of electrodes (<32 channels) and a template head model. This study demonstrated the validity and clinical utility of electric source imaging in a large prospective study. Given the low cost and high flexibility of electroencephalographic systems even with high channel counts, we conclude that electric source imaging is a highly valuable tool in pre-surgical epilepsy evaluation.

BACKGROUND: Data for trends in glycaemia and diabetes prevalence are needed to understand the effects of diet and lifestyle within populations, assess the performance of interventions, and plan health services. No consistent and comparable global analysis of trends has been done. We estimated trends and their uncertainties in mean fasting plasma glucose (FPG) and diabetes prevalence for adults aged 25 years and older in 199 countries and territories. METHODS: We obtained data from health examination surveys and epidemiological studies (370 country-years and 2·7 million participants). We converted systematically between different glycaemic metrics. For each sex, we used a Bayesian hierarchical model to estimate mean FPG and its uncertainty by age, country, and year, accounting for whether a study was nationally, subnationally, or community representative. FINDINGS: In 2008, global age-standardised mean FPG was 5·50 mmol/L (95% uncertainty interval 5·37-5·63) for men and 5·42 mmol/L (5·29-5·54) for women, having risen by 0·07 mmol/L and 0·09 mmol/L per decade, respectively. Age-standardised adult diabetes prevalence was 9·8% (8·6-11·2) in men and 9·2% (8·0-10·5) in women in 2008, up from 8·3% (6·5-10·4) and 7·5% (5·8-9·6) in 1980. The number of people with diabetes increased from 153 (127-182) million in 1980, to 347 (314-382) million in 2008. We recorded almost no change in mean FPG in east and southeast Asia and central and eastern Europe. Oceania had the largest rise, and the highest mean FPG (6·09 mmol/L, 5·73-6·49 for men; 6·08 mmol/L, 5·72-6·46 for women) and diabetes prevalence (15·5%, 11·6-20·1 for men; and 15·9%, 12·1-20·5 for women) in 2008. Mean FPG and diabetes prevalence in 2008 were also high in south Asia, Latin America and the Caribbean, and central Asia, north Africa, and the Middle East. Mean FPG in 2008 was lowest in sub-Saharan Africa, east and southeast Asia, and high-income Asia-Pacific. In high-income subregions, western Europe had the smallest rise, 0·07 mmol/L per decade for men and 0·03 mmol/L per decade for women; North America had the largest rise, 0·18 mmol/L per decade for men and 0·14 mmol/L per decade for women. INTERPRETATION: Glycaemia and diabetes are rising globally, driven both by population growth and ageing and by increasing age-specific prevalences. Effective preventive interventions are needed, and health systems should prepare to detect and manage diabetes and its sequelae. FUNDING: Bill & Melinda Gates Foundation and WHO.

Dass der Weg der parlamentarischen Mitwirkung im Bereich der Aussenpolitik steinig werden sollte, widerspiegelte sich bereits in der Entstehungsgeschichte der Aussenpolitischen Kommissionen (APK). Diese haben zum heutigen Zeitpunkt unter anderem dafür zu sorgen, dass das Parlament seine Mitwirkungsrechte in auswärtigen Angelegenheiten frühzeitig und wirk¬sam wahrnehmen kann. Nebst verschiedensten Instrumenten auf Verfassungs- und Gesetzesebene steht den APK ein wichtiges Mitwirkungsinstrument zur Verfügung: die Information und Konsultation gemäss Art. 152 Parlamentsgesetz (ParlG). Seit Inkrafttreten dieser Bestimmung im Dezember 2003 offenbart sich jedoch, dass sich die praktische Umsetzung des Gesetzesartikels mit den damaligen Vorstellungen des Gesetzgebers anlässlich der Erarbeitung dieses parlamentarischen Instrumentes nicht deckt. Der Gesetzgeber wies seiner¬zeit auf das für die Umsetzung bedeutende Vertrauensverhältnis zwischen Bundesrat und Parlament hin. Allerdings beeinflussen nun Spannungen und Konkurrenz zwischen der Exekutive und der Legislative die Umsetzung von Art. 152 ParlG. Die vorliegende Arbeit versucht, die geschichtlichen Hintergründe, die Entstehung, den Sinn und Zweck sowie die Praxis von Art. 152 ParlG vor dem Hintergrund des erwähnten Spannungsfelds und im Zusammenspiel mit den weiteren Mitwirkungsinstrumenten im Bereich der Aussenpolitik darzulegen. Comme le montre déjà l'historique des Commissions de politique extérieure (CPE), la participation du Parlement à la politique extérieure n'est pas dénuée d'obstacles. A l'heure actuelle, les CPE doivent notamment faire en sorte que le Parlement puisse faire valoir, en amont et avec efficacité, son droit de participation dans le domaine de la politique étrangère de la Suisse. Outre divers instruments figurant dans la Constitution et les lois, les CPE disposent d'un important moyen de participation: l'information et la consultation au sens de l'art. 152 de la loi sur le Parlement (LParl). Depuis l'entrée en vigueur de cette disposition en décembre 2003, il s'avère toutefois que l'application concrète de cet article de loi ne ré¬pond pas entièrement aux attentes du législateur lors de l'élaboration de cet instrument parlementaire. En effet, le législateur s'était alors basé sur la relation de confiance entre le Conseil fédéral et le Parlement, relation essentielle à la mise en oeuvre de cet article. La pratique montre cependant que la mise en oeuvre de l'art. 152 LParl est influencée par des tensions et par une relation de concurrence existant entre l'exécutif et le législatif. Le présent travail entend exposer le contexte historique de l'art. 152 LParl, son élaboration, son but et sa mise en oeuvre, tout en tenant compte des éléments de tension et des autres instruments permettant la participation en matière de politique extérieure.
