Consistent phenological shifts in the making of a biodiversity hotspot: the Cape flora
2011
Abstract Background The best documented survival responses of organisms to past climate change on short (glacial-interglacial) timescales are distributional shifts. Despite ample evidence on such timescales for local adaptations of populations at specific sites, the long-term impacts of such changes on evolutionary significant units in response to past climatic change have been little documented. Here we use phylogenies to reconstruct changes in distribution and flowering ecology of the Cape flora - South Africa's biodiversity hotspot - through a period of past (Neogene and Quaternary) changes in the seasonality of rainfall over a timescale of several million years. Results Forty-three dist…
Educación artística : revista de investigación
2016
Resumen: El siguiente articulo pretende identificar posibles espacios comunes entre arte y educacion partiendo de la propuesta artistica Mapa dels Desitjos [1] del colectivo Crater [2] . Esta propuesta se llevo a cabo en el contexto de la XVII Mostra d’Art Public / Universitat Publica de la Universitat de Valencia. Mapa dels Desitjos surgio de la idea de preguntar a la comunidad universitaria como organizarian su vida si no tuviesen en cuenta la cuestion economica y de hacer publicas sus respuestas. A partir de esta experiencia, analizamos y reflexionamos en torno a cuatro preguntas que estructuran el analisis: ?Que paralelismos existen entre los roles de artista/publico y maestro/estudiant…
In Defense of Cities : On Negative Presentation of Urban Areas in Environmental Preference Studies
2019
This paper critiques a common research method, image-based studies, in assessing environmental preferences. The method is used, in particular, in the fields of environmental psychology, landscape studies, and health studies, here called empirical environmental preference studies or EEP studies. I argue that the established view in the EEP field that nature is inherently experienced as more aesthetically appealing and restorative than urban environments may be biased because of the image-based method. This paper presents a literature review of EEP studies, discussing them in a framework of environmental and everyday aesthetics. The conclusion is that EEP studies may strip cities of their phy…
Depositional environment of the tidally-dominated transgressive succession: Rēzekne and Pärnu regional stages, Baltic devonian basin
2013
Disertācijas pētijumu tēma ir veltīta Rēzeknes un Pernavas reģionālo stāvu nogulumu fāciju pētījumiem un to uzkrāšanās vides rekonstrukcijai Baltijā. Agrākie pētījumi šajā devona klastisko nogulumu slāņkopas daļā tika veltīti galvenokārt litoloģiskiem, mineraloģiskiem un stratigrāfiskiem pētījumiem, kā arī nogulumu sastāva pētījumiem baseina austrumdaļā. Detalizēti pētījumi ar mērķi rekonstruēt kopējo baseina attīstību līdz sim netika veikti. Tādēļ, Rēzeknes un Pērnavas reģionalo stavu slāņkopas veidošanas apstākļi bija maz zināmi, kā arī diskutabli. Pēdējo desmit gadu laikā fāciju analīzes loma seno baseinu rekonstrukcijās tika plaši pielietota vidus un augšdevona klastiskās slāņkopas pētī…

Evaluating the Authenticity of Virtual Environments: Comparison of Three Devices
2016
Immersive virtual environments (VEs) have the potential to provide novel cost effective ways for evaluating not only new environments and usability scenarios, but also potential user experiences. To achieve this, VEs must be adequately realistic. The level of perceived authenticity can be ascertained by measuring the levels of immersion people experience in their VE interactions. In this paper the degree of authenticity is measured via anauthenticity indexin relation to three different immersive virtual environment devices. These devices include (1) a headband, (2) 3D glasses, and (3) a head-mounted display (HMD). A quick scale for measuring immersion, feeling of control, and simulator sick…
Immersion revisited:A review of existing definitions of immersion and their relation to different theories of presence
2016
The term immersion continues to be applied inconsistently within and across different fields of research connected with the study of virtual reality and interactive media. Moreover, immersion is oftentimes used interchangeably with the terms presence and engagement. This article details a review of existing definitions of immersion originating within the study of video games, virtual environments, and literary works of fiction. Based on this review, a three-dimensional taxonomy of the various conceptualizations of immersion is proposed. That is, the existing definitions of immersion may be broadly divided into three categories, each representing a dimension of the taxonomy: immersion as a p…
Modifications over years of volatile compounds and agronomic features in a Sicilian Clary sage biotype.
2006
Clary sage is a biennial native to Mediterranean area, spontaneous and often ubiquitous in many environments of inner Sicily. The large white-pinkish flowers are used, besides for ornamental purposes, for extracting a strongly-scented essential oil largely used by perfume industries. This work has been carried out with the aim to observe over several years the behaviour of a Sicilian Clary sage biotype, grown on experimental plots laid out in Sparacia (Cammarata - AG - Sicily). For this purpose seeds of Clary sage collected from a wild population growing in Pietraperzia (EN) were sown in experimental plots each year for seven consecutive years (from 1998 to 2005). Since Clary sage is a bien…
VIRTUAL CLASSROOM: TEACHER SKILLS TO PROMOTE STUDENT ENGAGEMENT
2018
The Virtual Classroom is the main tool for blended learning, since it allows the breaking of time and space barriers between the teacher and the student. In order to develop and put into practice a higher studies course through this tool, teachers need to have a series of skills related to the command of digital technologies and an understanding of students’ affective and behavioral states: and to then apply appropriate communication strategies to deliver course content and prepare students for this innovative learning approach. This study reviews educational research literature on virtual classrooms, teacher behavior and student engagement to establish a theoretical model that explains the…
¿Influye la Retroalimentación Correctiva en el Uso de la Retroalimentación Elaborada en un Entorno Digital?
2019
Los entornos digitales permiten proporcionar retroalimentación correctiva de verificación de respuestas (KR: correcto/incorrecto) o de respuesta correcta (KCR: la respuesta correcta es X), junto con retroalimentación elaborada (EF: explicaciones). Es frecuente asumir que los estudiantes procesan la EF, aunque investigaciones recientes demuestran que eso no siempre es así, debido probablemente a la retroalimentación correctiva proporcionada junto con la EF. El objetivo de este trabajo es analizar la decisión voluntaria de acceder a EF en función de la retroalimentación KR y KCR recibida inmediatamente tras responder preguntas de un texto de ciencias. Estudiantes de secundaria recibieron retr…
