Zientzien irakaskuntza: Argumentazio gaitasuna eta datuen erabilera sustatzeko esku-hartze proposamen berritzailea

Gaur egun, konpetentzia zientifikoen garapena Lehen Hezkuntzako eskolan gutxi garatuta eta eztabaidagarria den gaia da. Ikasleek kultura zientifikoan murgiltzeko forma aurkitu eta, bereziki, argumentazio gaitasuna garatzen laguntzea, zientziak hitz egiteko aukerak emanez, ez da batere arrunta gure eskoletan. Esku-hartze berritzaile hau egoera honi aurre egiteko eta arazoari irtenbide bat bilatzeko diseinatuta izan da. Honen bidez, Lehen Hezkuntzan zientzienganako interesa sustatzen saiatzen da, zientziako klaseetan datuen erabilerari eta argumentazioari lehentasuna emanez. Ekimena 2013-2014ko martxoan jarri da martxan.

Contribución al estudio de las estructuras tumulares en arqueología: entre la similitud morfológica y la disparidad de funciones

[ES] El artículo trata el tema de las estructuras tumulares, su variabilidad formal y funcional (funeraria, lugar de habitación, etc.), así como su distinta cronología. Se describe los casos concretos de Txoritegi (Zerain —Gipuzkoa—) y Galardi (Txoritegi —Gipuzkoa—), unas estructuras tumulares tipo mota utilizadas, posiblemente, a modo de atalaya de vigía en el contexto del período de conflictividad bajomedieval. Es un elemento novedoso en el territorio para cuya interpretación se ha efectuado un análisis de las cuencas visuales mediante SIG.

Usage of substances and their dosage regimes in pharmacological animal models of schizophrenia

Background: Contrary to what is generally thought schizophrenia is a very common mental health issue. For this, several animal models are used to assess the illness in order to develop a definitive. The most widely spread paradigm is the use of pharmacological models. Aim: The aim of this review is to display which are the most used insults for the assessment of social behaviour related negative symptoms in animal models as well as to ascertain which is the most adequate regime. Design: Literature review. Methods: PubMed database was used for this article by the search of the indexed “schizophrenia”, “animal models”, “social behaviour” and “negative symptoms” descriptors. With the exception of a single article due to it value this review is based on articles from 10 years onwards. Besides, only clinical trials and reviews written in English or Spanish and that had laboratory rodents as target population were accepted. Results: The studies assessed agree that pharmacological models (specially those regarding the NMDA receptor antagonists) are a valuable means for the experimental investigation of negative symptoms in schizophrenia with the necessity to emphasise that only some negative symptoms (anhedonia and social interaction, mainly) can be experimentally assessed. Conclusions: There is not enough evidence regarding the fours aspects of this review. PCP, Ketamine or MK-801 in sub-acute dosage regimes are currently the most indicated insults to mimic schizophrenic symptoms in rodents, although further research in needed, albeit other substances are valuable as well.
