Revision of New World Species of the Shore-fly Subgenus Allotrichoma Becker of the Genus Allotrichoma with Description of the Subgenus Neotrichoma (D…
2012
The New World species of the subgenera Allotrichoma Becker and Neotrichoma (new subgenus) are revised, including a phylogenetic analysis of the species groups and subgenera within the genus Allotrichoma. For phylogenetic perspective and to document the monophyly of the genus Allotrichoma and its included subgenera and species groups, we also provide a cladistic analysis of genera within the tribe Hecamedini. The ingroup included seven exemplar congeners from within Allotrichoma. Outgroup sampling included exemplars of other genera within Hecamedini and from the putative sister group, Lipochaetini, and to root the analysis, we used an exemplar of the tribe Discocerinini. Analyses with succes…
New western Palaearctic Dinotrema species with mesoscutal pit and only medially sculptured propodeum (Hymenoptera, Braconidae, Alysiinae)
2013
Descriptions of four new species of the genus Dinotrema Foerster with a mesoscutal pit and only medially sculptured propodeum are given. Dinotrema alysiae sp. n. (Denmark, England, Netherlands, Spain), D. paramicum sp. n. (Denmark, Finland), D. tirolense sp. n. (Italy) and D. valvulatum sp. n. (Denmark, Italy).
Living on the edge: Meoneura obscurella in the ‘Wieliczka’ Salt Mine (southern Poland) exhibits the first case of lecithotrophic ovoviviparity in the…
2021
During the studies on the invertebrate fauna of the subterranean part of the “Wieliczka” Salt Mine in Wieliczka, Poland, the presence of many specimens of the dipteran species Meoneura obscurella (Fallén 1823) was observed. Organic remains and faeces related to the presence of mice (Mus musculus) were indicated as a potential food source for the insects. M. obscurella displays lecithotrophic viviparity (ovoviviparity), which has developed due to extremely harsh abiotic conditions and a lack of food. This is the first documented case of lecithotrophic viviparity within the fly family Carnidae. Based on the ability of this species to inhabit and reproduce in the conditions of the subterranean…

Resumen basado en el de la publicación Título, resumen, palabras clave en español e ingles Se analizan los resultados de tres estudios de caso en dos escuelas rurales de México y una de Ecuador. Se comparan los índices de paridad de género (IPG) fijando el análisis en dos dimensiones : la inscripción/asistencia y el desempeño en la alfabetización. Se generaron en los resultados una hipótesis tentativa que sugiere un marco conceptual para una propuesta de investigación más amplia. Se propone con base en la evidencia de estudios previos de un importante avance en el índices de paridad de género en la región latinoamericana, la evaluación del aprovechamiento escolar en la lectoescritura en esc…

Il contributo, traendo spunto dalla disamiina di una pronuncia del T.A.R. Veneto (15 gennaio 2009, n.620) affronta il tema dell'applicabilità della normativa sul volontariato alle associazioni laicali d'indole confessionale.
It takes time to see the menu from the body: an experiment on stable isotope composition in freshwater crayfishes
2015
For many applications and ecological studies in which wild individuals are brought to laboratory it would be essential to know accurately how fast novel diet is reflected in composition of different tissues. To study the effects of two different diets on the stable isotope composition of freshwater crayfish muscle and hemolymph, we conducted a three month experiment on noble crayfish (Astacus astacus) and signal crayfish (Pacifastacus leniusculus) by feeding them sweet corn (Zea mays) or Baltic herring (Clupea harengus membras) as novel food. During the experiment, the crayfish were given 0.4 g of selected food daily and the amount consumed was recorded. The samples for the stable isotope a…
Towards Natural Engagement in Nonexhibitional Dramatic Role-Plays
2003
Modern language teaching and drama have long had a tenuous relationship. Foreign/second language teaching (F/SLT) and Language for Specific Purposes (LSP) instruction often mistakenly associate drama with learning games and role-play simulations. However, these remedial activities, though useful, offer only limited opportunities for natural speech interaction. This article argues that, as a natural dialogical process of cognitive and affective involvement, nonexhibitional dramatic role-play generates authentic meaning through action and personal commitment.
Valenza e insegnamento della lingua straniera
2015
This work deals with valency, a key syntactic notion whose chemistry-inspired label was established by Lucien Tesnière (1959), one of the most well-known contributors to the Prague Linguistic Circle. We will concentrate on two questions: (a) to what extent does valency play a role in Second Language Learning (SLL)?; and (b) what role should the use of valency play in language teaching practices? This paper will provide answers to these questions and propose reasons for motivating the use of valency in SLL.
Actividad Física y entorno construido en adolescentes y adultos jóvenes
2015
Objectives. This study aims to analyse physical activity (PA) levels of high school and university students; to estimate their perception of built environment with regard to physical PA; and to assess the relation between PA and built environment. Methods. A sociological cross-sectional study with non-experimental design was applied. The International Physical Activity Questionnaire and the Built Environment Characteristics Questionnaire were filled in by a sample of 1.862 students from high schools and the university in Granada, Spain. Results. High school students were significantly more active than university students, the latter reaching insufficient levels of PA. Nevertheless, they con…
Hvordan kan teknologi skape nye undervisnings- og læringsmåter i fremmedspråksundervisningen fram mot 2030?
2014
Published version of an article in the journal: Acta Didactica Norge. Also available from the publisher at: http://adno.no/index.php/adno/article/view/358/393 Open Access I denne artikkelen drøfter jeg hvordan teknologi kan skape nye undervisnings- og læringsmåter i fremmedspråksundervisningen fram mot 2030. Jeg starter med å skissere et mulig framtidsscenario i form av et blogginnlegg skrevet av en 15 åring i året 2030. Videre i artikkelen tar jeg utgangspunkt i dette framtids-scenarioet og sammenligner det med dagens situasjon, i tillegg til at jeg drøfter hva som må til for at scenarioet kan oppfylles. Læreren spiller en nøkkelrolle i utviklingen av nye undervisnings- og læringsmåter, og…
