Enseñanza de la lengua escrita. ¿A qué edad?

Resumen

En este estudio se pasa revista a la polémica suscitada, ya desde antiguo, en torno a la edad de comienzo de la enseñanza formal de la lengua escrita.

A la luz de las opiniones vertidas por distintos autores, y contando con la muy valiosa aportación de profesores con larga experiencia en educación preescolar, se analizan tanto la posibilidad de un aprendizaje precoz como la oportunidad de tan temprano comienzo.

El autor del artículo señala, como conclusión, lo improcedente de una iniciación precoz en la enseñanza de la lecto-escritura, si con ello se dificulta el tratamiento de aspectos de mayor transcendencia en la formación del niño en los primeros estadios de su vida.     

Defining the problem: key element for the success of knowledge management

The objective of this paper is to propose a methodology for applying knowledge management (KM), in which we first focus on explaining problematic areas of an organization by identifying the knowledge core process, before applying KM strategies to those processes. For the methodology, we lean on the larger context of systems thinking to help visualize the whole organization, and it is here that the key factors are identified and a set of strategic criteria is established. The most important criteria are then used to evaluate the associated processes and their respective tasks in order to establish the problematic areas or opportunities where KM initiatives can be applied. This strategy precludes tackling all the organization's problems and allows management to focus on only those processes that provide significant and manageable knowledge. Finally, this study explores and cautiously recommends an unexploited but valuable element to be taken into account when implementing KM initiatives.     

Energy: Between Physics and Metaphysics

The general concept of energy is somewhat unclear as long as it is confined to physics, since every chapter of it defines its own particular concept of energy. The general concept can be elucidated in terms of the hypergeneral (philosophical) concepts of concrete thing and changeability. In this way one succeeds in crafting a minitheory that identifies energy with mutability, and that regards it, as well as its conservation, as a universal property of concrete things. The moral is that physicists and philosophers can learn from one another.     

Ein interaktionsbasiertes Modell für den objektorientierten Integrations- und Regressionstest

Zusammenfassung.   Bei der iterativen, inkrementellen Software-Entwicklung werden Klassen sukzessive spezifiziert, implementiert bzw. ge?ndert oder erweitert, klassengetestet und zu einem ausführbaren Anwendungssystem integriert. Integrations- und Regressionstest stellen dabei besonders wichtige und h?ufig ausgeführte Testaktivit?ten dar, die zudem aufgrund der vielf?ltigen Interaktionsm?glichkeiten in objektorientierten Programmen sehr komplex sind. Integrations- und Regressionstest werden in der Literatur stets separat behandelt, obwohl sie durchaus ?hnliche Teilaktivit?ten beinhalten. Bestehende Ans?tze zum objektorientierten Integrationstest betrachten entweder strukturelle oder verhaltensorientierte Systembeschreibungen. In diesem Beitrag stellen wir das Klassen-Botschaftsdiagramm (KBD) vor, ein Struktur und Verhalten objektorientierter Programme gleicherma?en berücksichtigendes interaktionsbasiertes (Test-)Modell. Wir skizzieren Algorithmen zur ?nderungsanalyse, Ableitung einer Integrationsstrategie und Auswahl von Regressionstestf?llen nach der Modifikation bestehender Klassen. Abschlie?end werden die Ergebnisse einiger mit Smalltalk-80 Klassen durchgeführter Experimente zur Evaluierung des Verfahrens vorgestellt. Eingegangen am 14. Dezember 1999 / Angenommen am 19.

Harmonization of pre-analytical quality indicators

Quality indicators (QIs) measure the extent to which set targets are attained and provide a quantitative basis for achieving improvement in care and, in particular, laboratory services. A body of evidence collected in recent years has demonstrated that most errors fall outside the analytical phase, while the pre- and post-analytical steps have been found to be more vulnerable to the risk of error. However, the current lack of attention to extra-laboratory factors and related QIs prevent clinical laboratories from effectively improving total quality and reducing errors. Errors in the pre-analytical phase, which account for 50% to 75% of all laboratory errors, have long been included in the ‘identification and sample problems’ category. However, according to the International Standard for medical laboratory accreditation and a patient-centered view, some additional QIs are needed. In particular, there is a need to measure the appropriateness of all test request and request forms, as well as the quality of sample transportation. The QIs model developed by a working group of the International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) is a valuable starting point for promoting the harmonization of available QIs, but further efforts should be made to achieve a consensus on the road map for harmonization.     

Self-reported symptoms and risk factors for digital ischaemia among international world-class beach volleyball players

The prevalence of ischaemia-related symptoms is remarkably high among elite indoor volleyball players. Since the exposure to sport-specific demands may be higher in beach volleyball compared to indoor volleyball, the aim of this study was to assess the prevalence of ischaemia-related symptoms and associated risk factors among world-class beach volleyball players. Therefore, a questionnaire survey was performed among beach volleyball players active during the 2013 Grand Slam Beach Volleyball in the Netherlands. In total, 60 of the 128 beach volleyball players (47%) participated: 26 males and 34 females from 17 countries. The self-reported prevalence of cold or blue or pale digits in the dominant hand during or immediately after practice or competition was 38% (n = 23). Two risk factors were independently associated with symptoms of blue or pale digits: more than 14 years playing volleyball (odds ratio (OR) 4.42, 90% confidence interval (90% CI) 1.30–15.07) and sex (female) (OR 4.62, 90% CI 1.15–18.57). In conclusion, the prevalence of symptoms associated with digital ischaemia is high among international world-class beach volleyball players. Female sex and the length of the volleyball career were independently associated with an increased risk of ischaemia-related symptoms. The high prevalence of these seemingly innocuous symptoms and possible associated risk factors warrant regular monitoring since early detection can potentially prevent thromboembolic complications and irreversible tissue damage.     

ANALYSIS OF CONTENTS,CONTRIBUTORS, AND RESEARCH DIRECTIONS: MAPPING PUBLICATION ROUTES IN THE JOURNAL

A content analysis of the journal Religious Education: An Interfaith Journal of Spirituality, Growth and Transformation was conducted for a 10-year period between 1993–2002 (Volume 88, 1–Volume 97, 4). A total of 325 articles (277 authors) were analyzed into 3 primary research directions (theoretical, qualitative, and quantitative). Author institutional affiliation, religious identity, position, geographic location, and number of contributions were also computed. Implications for the Journal and the field of religious education are discussed.     

Knowledge: Genuine and Bogus

Pseudoscience is error, substantive or methodological, parading as science. Obvious examples are parapsychology, ??intelligent design,?? and homeopathy. Psychoanalysis and pop evolutionary psychology are less obvious, yet no less flawed in both method and doctrine. The fact that science can be faked to the point of deceiving science lovers suggests the need for a rigorous sifting device, one capable of revealing out the worm in the apple. This device is needed to evaluate research proposal as well as new fashions. Such a device can be designed only with the help of a correct definition of science, one attending not only to methodological aspects, such as testability and predictive power, but also to other features of scientific knowledge, such as intelligibility, corrigibility, and compatibility with the bulk of antecedent knowledge. The aim of this paper is to suggest such a criterion, to illustrate it with a handful of topical examples, and to emphasize the role of philosophy in either promoting or blocking scientific progress. This article is a revised version of a chapter in the author??s forthcoming book Matter and Mind (Springer). [The Appendix on inductive logic was written at the request of the editors in order to elaborate claims made in #10 (4).]
