Sabiedrisko organizāciju loma Turcijas pievienošanās procesā ES.
2016
"Pilsoniskās sabiedrības organizācijas" ir vienas no būtiskākajiem spēlētājiem pēdējā laika sarunu procesos ar Turciju un ES. Eiropas Savienība pievērš lielu uzmanību tam, lai veidotu kontaktu un sadarbotos ar pilsoniskās sabiedrības organizācijām kandidātvalstīs. Šajā kontekstā Turcija, kā kandidātvalsts, cenšas turpināt šo procesu pilsoniskās sabiedrības dialoga ietvaros, kas pirms tam ir ticis palēnināts politiskās situācijas dēļ, lai gan Turcijas ES kandidatūra ir kalpojusi par kritisku izvērtējumu Turcijas PSO vēsturiskajam insitucionālismam. Vēl jo vairāk, ES Eiropas Komisijas ģenerālsekretārs un Eiropas Komisijas delegācija Turcijā cenšas paātrināt procesu ar daudzveidīgiem projektie…
The object-tool duality in mathematical modelling. A framework to analyze students’ appropriation of Sankey diagrams to model dynamic processes
2020
Students often do not experience the relevance of learning mathematics. This paper reports on an exploratory case study, in which a class of grade 8 students (n=35) was introduced to Sankey diagrams. The aim was to explore to what extent these students could appropriate Sankey diagrams, meaning: they could describe these as objects in themselves and they could use them to model and visualize phenomena relevant to them. Based on Cultural-Historical Activity Theory, we developed an analytical construct defined as the object-tool duality, coordinating mathematics as a set of objects and as a set of tools. The analysis of students’ answers showed that they could use these diagrams as tools to v…
Key pedagogical principles and their major obstacles as perceived by comprehensive school teachers
2011
The general pedagogical knowledge of teachers is not often investigated in comparison to content knowledge and pedagogical content knowledge. In this article, a more comprehensive outlook on teache...
El género Hesperaloe Engelm. Cultivado en la Península Ibérica e Islas Baleares
2006
daguior@alumni.uv.es En este artículo citamos los taxones pertenecientes al género Hesperaloe Engelm. que están cultivados como ornamentales en la Península Ibérica e Islas Baleares: H. campanulata Starr, H. funifera subsp. funifera, H. parviflora (Torr.) J. Coulter, H. parviflora var. Engelmannii Trel., y H. parviflora cv. «Yellow», aportando datos corológicos, sinonímicos, etimologicos, históricos, y descripción de cada uno, así como mostramos unas claves dicotómicas de determinación. In this article we cite the cultivated taxa of the Hesperaloe Engelm. genus in Spain: H. campanulata Starr, H. funifera subsp. funifera, H. parviflora (Torr.) J. Coulter, H. parviflora var. engelmannii Trel.…
Premature diagnostic closure: An avoidable type of error
2013
A well-developed clinical interview makes it possible to adequately focus the diagnosis. However, cognitive psychology shows that mistakes are made when the persons face complex problems, such as those faced when making a diagnosis, especially if time or resources are limited. The main cause of failures in clinical reasoning is using "cognitive shortcuts". Among them, premature closure is a key factor triggering a diagnostic error. Cognitive errors are predictable and thus, it is possible to learn strategies to reduce or avoid them. Knowing the main features of cognitive shortcuts and identifying those automatically used is the first step towards preventing errors or minimizing their conseq…
Two new Antarctic species of Schizotricha (Cnidaria: Hydrozoa: Leptothecata) from US Antarctic expeditions
2004
Two species of the genus Schizotricha new to science (Schizotricha crassa sp. nov. and S. southgeorgiae sp. nov.) have been studied. Both species are described and figured and their systematic position amongst the remaining species of the genus is discussed. The material was collected during the United States Antarctic Research Programme (USARP) with RV 'Eltanin' and RV 'Islas Orcadas'. A comparative table listing the main features and distribution of the known species of Schizotricha, together with an identification key, are presented.
A reappraisal of the Pleurotus eryngii complex – New species and taxonomic combinations based on the application of a polyphasic approach, and an ide…
2014
The Pleurotus eryngii species-complex comprises choice edible mushrooms growing on roots and lower stem residues of Apiaceae (umbellifers) plants. Material deriving from extensive sampling was studied by mating compatibility, morphological and ecological criteria, and through analysis of ITS1-5.8S-ITS2 and IGS1 rRNA sequences. Results revealed that P. eryngii sensu stricto forms a diverse and widely distributed aggregate composed of varieties elaeoselini, eryngii, ferulae, thapsiae, and tingitanus. Pleurotus eryngii subsp. tuoliensis comb. nov. is a phylogenetically sister group to the former growing only on various Ferula species in Asia. The existence of Pleurotus nebrodensis outside of S…
Toll-quality digital secraphone
2002
This paper describes the design and performance of a secraphone that, when plugged between any conventional telephone set and the public telephone network, protects the speech information travelling through the PSTN. The device has a transparent operating mode that does not alter the signal and a secure mode, accessed upon request of any of the speakers, that encrypts the speech with digital techniques, assuring privacy against unwanted listeners. At the transmission branch, voice is sampled, coded with a CELP scheme at 9600 bps (with a slow mode at 7200 bps), encrypted with a proprietary algorithm and interfaced to the line with a V.32 modem chip set. The keys for encryption are establishe…
Gödel and the Blind Watchmaker
2015
While accepting that contingency is key to biological evolution, we wonder how much need there is for it. It is extremely difficult to talk about trends in evolution, but the fact remains that they are found here and there when evolutionary experiments are repeated. But we should ask, for example, whether there is an unavoidable tendency of life towards progressive complexity . This chapter deals with certain theoretical considerations from Logic and Computing on the conditions necessary to formulate a predictive evolutionary theory .
Analysis of Game Creativity Development by Means of Continuously Learning Neural Networks
2006
Experts in ball games are characterized by extraordinary creative behavior. This article outlines a framework of analyzing creative performance based on neural networks. The aim of this study is to compare the potential of different kinds of training programs with the learning of game creativity in real field contexts. The training groups (soccer group, n=20; field hockey group, n=17) showed significant improvement in comparison to the control group (n=18) with respect to the three measuring points, although no difference could be established between the groups. As regards the development of performance, five types of learning behavior can be distinguished, the most striking ones being what…
