Survival Rates of Young MagpiesPica picain a Mountain Population of Eastern Spain
2007
Abstract. The aim of this study was to estimate the survival of young Magpies between fledging and the next breeding season and to identify some of the factors affecting it. A total of 50 nestlings were colour-ringed in two breeding seasons in the valley of the Pitarque River (Teruel, E Spain), and were monitored weekly until May of the following year. 59 nestlings were also colour-ringed in two nearby localities (4–5 km) to detect possible dispersal to and from our study area. Mark-recapture analyses were used to estimate weekly survival, which was assumed to be constant for periods of four weeks in order to reduce the number of parameters. Models with the effect of time, age class, season…
Análisis de la percepción de la peligrosidad de inundación en el municipio de Tavernes Blanques (Valencia, España). Su papel en la valoración del rie…
2021
Resumen: La Comunidad Valenciana alberga numerosas cuencas pequeñas de dinámica torrencial donde la ocurrencia de avenidas puede afectar a zonas urbanas. La alta ocupación de estas zonas y la baja percepción del riesgo por parte de las poblaciones contribuyen al aumento de la vulnerabilidad, suponiendo la amenaza un riesgo mayor para los grupos humanos. El presente estudio aborda el análisis de la percepción del riesgo de inundación por parte de la población de Tavernes Blanques (Valencia), municipio catalogado como de alto riesgo de inundación por la AVSRE. Para ello se lleva a cabo una encuesta a la población residente en el municipio, cuyos resultados muestran una baja percepción del rie…
Introduction to the 5th International Workshop on Intelligent Environments Supporting Healthcare and Well-Being (WISHWell13)
2013
This workshop is designed to bring together researchers from both industry and academia from the various disciplines to discuss how innovation in the use of technologies to support healthier lifestyles can be moved forward. There has been a growing interest around the world and especially in Europe, on investigating the potential consequences of introducing technology to deliver social and health care to citizens (see for example [1]). This implies an important shift on how social and health care are delivered and it has positive as well as negative consequences which must be investigated carefully. On the other hand there is an urgency provided by the changes in demographics which is putti…
Assessment of Organizational Trust: Preliminary Data for Romanian Adaptation of the Organizational Trust Inventory Short Form
2013
Abstract In the last years, trust became an important variable in regard to the well-being of organizations. In Romania, it was included in studies as a variable but there are few instruments that measure organizational trust. Therefore I identify a necessity for developing instruments useful in assessing and promoting any organizational adjustments. This paper presents the preliminary data obtained in the process of adaptation of OTI for the Romanian population. In doing so, we followed the guidelines of ITC. Using a sample of 108 employees the psychometric results show that OTI-RO has a high level of internal consistency reliability (a = 0.94) and it can be used exclusive for equivalent p…
Towards a Framework for Cross-Sector Collaboration: Implementing a Resilience Information Portal
2017
Municipalities play an integral part in the strive for resilient societies. A resilient municipality is not only prepared for short-term shocks such as natural disasters but also more successful in mastering long-term stresses such as profound in-creases or decreases of population. Backed by a large-scale research project we have developed a Resilience Information Portal (RIP). It serves as an artefact to support cross-sector collaboration within a municipality. The core challenges in implementing such a portal reside not in the technological work, though. Rather, it needs to be implemented in the communication and IT strategy of a municipality and be tailored to the processes. In this arti…
Positive and Negative Media Effects on University Students’ Learning: Preliminary Findings and a Research Program
2019
Research in communication science highlights positive as well as negative effects of news and social media on learning but focuses predominantly on the largely unintended knowledge acquisition of the overall population. Research in educational science deals with students’ knowledge acquisition but is largely limited to formal learning such as in university courses. In this paper, we report findings of a pilot study combining both approaches by dealing with mass and social media effects on university students’ learning. While this study reveals several effects, their influences and causality remain largely unclear. Therefore, we propose a research program to explain positive and negative med…
Ancient xenocrystic zircon in young volcanic rocks of the southern Lesser Antilles island arc
2017
Abstract The Lesser Antilles arc is one of the best global examples in which to examine the effects of the involvement of subducted sediment and crustal assimilation in the generation of arc crust. Most of the zircon recovered in our study of igneous and volcaniclastic rocks from Grenada and Carriacou (part of the Grenadines chain) is younger than 2 Ma. Within some late Paleogene to Neogene (~ 34–0.2 Ma) lavas and volcaniclastic sediments however, there are Paleozoic to Paleoarchean (~ 250–3469 Ma) xenocrysts, and Late Jurassic to Precambrian zircon (~ 158–2667 Ma) are found in beach and river sands. The trace element characteristics of zircon clearly differentiate between different types o…
Knowledge-building patterns in educational dialogue
2017
This study aimed to examine knowledge-building patterns in Grade 6 educational dialogues. The data consisted of 20 video-recorded lessons from the classes taught by seven teachers, selected by using a latent profile analysis and examined with a qualitative functional analysis of classroom talk. Episodes of educational dialogue were found to represent three main types of knowledge, based on facts, views and experiences. These three types were further identified as forming six diverse knowledge-building patterns in educational dialogues. The findings indicated that factual orientation dominated the Grade 6 lesson dialogues. However, factual knowledge building often occurred with the other two…
Educational dialogue in the classroom : scaffolding, knowledge building and associations with academic performance
2018
The present thesis focuses on patterns of educational dialogue, their quality with respect to forms of teacher scaffolding and shared knowledge building, and the association between the quality of educational dialogue and students’ academic performance. The specific questions of interest are as follows: (1) to examine how teachers scaffold students in learning situations through dialogic teaching, (2) to identify patterns of shared knowledge building in educational dialogues, and (3) to investigate how the quality of educational dialogue is associated with academic performance. The data were drawn from the audio- and video-recorded lessons of the First Steps longitudinal study, which were c…
Primary Student-Teachers’ Practical Knowledge of Inquiry-Based Science Teaching and Classroom Communication of Climate Change
2015
A teacher’s practical knowledge contains the teacher’s beliefs about the goals, values and principles of education that guide his or her actions in the classroom. There is still a lack of knowledge about how teachers’ practical knowledge influences their teaching. The present study examines student teachers’ practical knowledge in the context of teaching climate change in elementary schools. Participating student-teachers planned their lessons using the principles and ideas of inquiry-based science teaching and the communicative approach. The same two approaches were applied in analysing the lessons, providing a broader basis on which to study student-teachers’ beliefs about teaching scienc…
