Housing Affordability for Urban Regions
2021
Urban regions are recognised as driving forces of the global economy as well as the main sources of social inequality. In recent decades, particularly, housing access has become a serious problem, not only for the most disadvantaged population, but also for the middle class, as a result of economic crises and despite of prices decline in the housing market. In urban regions with high population density, some social groups face problems of housing affordability that depend not only on market prices but also on income availability. The contribution proposes a methodology for income-threshold assessment through a combination between the ratio income and the residual income approaches, which is…
Parenting, Peer Relationships, Academic Self-efficacy, and Academic Achievement: Direct and Mediating Effects
2017
The aim of the present study is to analyze the relation between authoritative and permissive parenting styles with the kinds of adolescent peer relationships (attachment, victimization, or aggression), and of the latter ones, in turn, with academic self-efficacy, and academic performance, in three waves that range from the early-mid adolescence to late adolescence. Five hundred Spanish adolescents, of both sexes, participated in a three-wave longitudinal study in Valencia, Spain. In the first wave, adolescents were either in the third year of secondary school or the fourth year of secondary school. The mean age in the first wave was 14.70 (SD = 0.68; range = 13–16 years). Child Report of Pa…
The Affordances of Reading/Writing on Paper and Digitally in Finland
2014
The aim of this study is to investigate the impact of digital technologies on reading and writing in Finland. The perceived affordances of reading and writing on paper and digitally are compared by analysing written essays collected from 25 communication students in 2013. Research design is replicated from a study of Fortunati and Vincent that concerns Italian students. Results show that Finnish students perceive more positive than negative affordances regarding reading on paper, while reading on screen attracts fewer virtues. In this respect, results are in line with the Italian study. Unlike in Italy, students in Finland value writing on a keyboard especially because it enables editing th…
Varying numbers of players in small-sided soccer games modifies action opportunities during training
2014
This study examined the effects of the numbers of players involved in small-sided team games (underloading and overloading) on opportunities for maintaining ball possession, shooting at goal and passing to teammates during training. These practice constraint manipulations were assumed to alter values of key performance variables identified in previous research, such as interpersonal distances between players and time to intercept shots and passes. Fifteen male soccer players (age: 19.60±1.99 years) were grouped into three teams and played against each other in different versions of small-sided soccer games, in which the number of players was manipulated in three different conditions: 5 vs. …
Evidence for Transmission of Taenia solium Taeniasis/Cysticercosis in a Rural Area of Northern Rwanda
2021
Cysticercosis is a parasitic infection caused by the metacestode larval stage (cysticercus) of Taenia solium. In humans, cysticercosis may infect the central nervous system and cause neurocysticercosis, which is responsible for over 50,000 deaths per year worldwide and is the major cause of preventable epilepsy cases, especially in low-income countries. Cysticercosis infection is endemic in many less developed countries where poor hygiene conditions and free-range pig management favor their transmission. A cross-sectional study was conducted in 680 children from a rural primary school in Gakenke district (Northern province of Rwanda). Stool samples were collected from participants and analy…
Ethnographic context and spatial coherence of climate indicators for farming communities : a multi-regional comparative assessment
2015
Accurate seasonal predictions of rainfall may reduce climatic risks that farmers are usually faced with across the tropical and subtropical zones. However, although regional-scale seasonal amounts have regularly been forecasted since 1997/98, the practical use of these seasonal predictions is still limited by myriad factors. This paper synthesizes the main resultsof a multi-disciplinary ethnographic and climatic project (PICREVAT). Its main objective was to seek the climatic information ? beyond the seasonal amounts ? critical for crops, both as an actual constraint to crop yields and as identified by the current and past practices and perceptions of farmers. A second goal was to confront t…
Investigating the Affordances and Constraints of SimReal for Mathematical Learning : A Case Study in Teacher Education
2019
Visualizations tools are one of the most innovative technologies that emerged the last few years in educational settings. They provide new potentialities for mathematical learning by means of dynamic animations and representations, interactive simulations, and live streaming of lessons. Moreover, visualization tools have the potential to foster a visual, dynamic, distributed, and embodied mathematics rather than individual achievements and static representations. This paper uses the visualization tool SimReal in teacher education to explore the affordances of the tool for learning mathematics. It proposes a framework that captures the affordances of SimReal at a technological, pedagogical, …
Efficient Hot Electron Transfer in Quantum Dot-Sensitized Mesoporous Oxides at Room Temperature
2018
Hot carrier cooling processes represent one of the major efficiency losses in solar energy conversion. Losses associated with cooling can in principle be circumvented if hot carrier extraction toward selective contacts is faster than hot carrier cooling in the absorber (in so-called hot carrier solar cells). Previous work has demonstrated the possibility of hot electron extraction in quantum dot (QD)-sensitized systems, in particular, at low temperatures. Here we demonstrate a room-temperature hot electron transfer (HET) with up to unity quantum efficiency in strongly coupled PbS quantum dot-sensitized mesoporous SnO2. We show that the HET efficiency is determined by a kinetic competition b…
Work engagement y su relación con la performance y la satisfacción laboral
2018
El presente trabajo, basado en los aportes de la Psicología Organizacional Positiva (POP),consistió en un análisis del concepto de Work Engagement. Por un lado, se buscó explorar las concepciones que tienen personas con personal a cargo sobre el work engagement mediante entrevistas realizadas a 38 voluntarios de la población general de la Ciudad de Buenos Aires y el conurbano bonaerense (18 hombres, 47.37%; 20 mujeres, 52.63%). La edad promedio fue de 49.87 años (DE = 9.48). Del análisis de contenido realizado se obtuvieron una serie de categorías que reflejan concepciones acerca del engagement. Por ejemplo, los participantes consideraron que las personas con engagement son aquellasque mues…
Palaeontological Virtual Congress: A new way to make science
2019
On the first month of 2018, one of the authors (VDC) of this preface had an interesting idea: to hold a virtual congress. At first, he did not know of the existence of this kind of congress, but a quick internet search showed him that there were some examples in the fields of medicine and veterinary medicine; however, it had never been done in palaeontology. For that reason, with the help of other co-workers from the Universitat de València, Museo Paleontológico de Alpuente and Museu Valencià d’Historia Natural, we decided to undertake this adventure.
