Peri-Implant Behavior of Tissue Level Dental Implants with a Convergent Neck
2021
Introduction: The aim of this retrospective study was to analyze the radiographic peri-implant bone loss of bone level implants and tissue level implants with a convergent neck in screw-retained single crowns and in screw-retained fixed partial prostheses, after two years of functional loading. Materials and methods: The sample was divided into two groups according to their type: Group I: supracrestal implants with convergent transmucosal neck
Unlocking mixed oxides with unprecedented stoichiometries from heterometallic metalorganic frameworks for the catalytic hydrogenation of CO 2
2021
[EN] Their complex surface chemistry and high oxygen lattice mobilities place mixed-metal oxides among the most important families of materials. Modulation of stoichiometry in mixed-metal oxides has been shown to be a very powerful tool for tuning optical and catalytic properties. However, accessing different stoichiometries is not always synthetically possible. Here, we show that the thermal decomposition of the recently reported metal-organic framework MUV-101(Fe, Ti) results in the formation of carbon-supported titanomaghemite nanoparticles with an unprecedented Fe/Ti ratio close to 2, not achievable by soft-chemistry routes. The resulting titanomaghemite phase displays outstanding catal…
Neurocognitive Predictors of Response to Intervention With GraphoGame Rime
2021
This study explores the neurocognitive predictors of response to intervention with GraphoGame Rime, an adaptive software game designed to aid the learning of English phonics. A cohort of 398 children (aged 6 – 7 years) who had participated in a recent Randomized Controlled Trial (RCT) of GraphoGame Rime in the United Kingdom were studied. Half were randomly assigned to play GraphoGame Rime (GG Rime) and the other half were assigned to Business As Usual (BAU). A series of pretests were given prior to the intervention to all participants, designed to measure phonological awareness skills, executive function (EF) skills and the ability to synchronise finger tapping to a rhythmic beat. Finger t…
Self-regulatory efficacy and sources of efficacy in elementary school pupils: Self-regulatory experiences in a population sample and pupils with atte…
2019
In this study, we examined self-regulatory efficacy and sources of self-efficacy (mastery experiences, vicarious experiences, social persuasion and physiological/emotional states) and the relationships between self-efficacy and its sources among elementary school pupils. Two groups were compared: a population sample (PS, N = 1284) and pupils with difficulties in attention and executive functions (AED, N = 61). Data gathered from self-report questionnaires indicated that pupils in the PS group had more positive efficacy beliefs and mastery experiences and fewer negative physiological/emotional states than the AED group. Analyses showed strong connections between sources and self-regulatory e…
Lexically specific vs. productive constructions in L2 Finnish
2020
ABSTRACTIt is assumed from a usage-based perspective that learner language constructions emerge from natural language use in social interaction through exemplar learning. In L1, young learners have been shown to develop their constructions from lexically specific, formulaic expressions into more productive, abstract schemas. A similar developmental path has been shown for L2 development, with some exceptions. The aim of the current study is to explore to what extent the default assumption holds for L2 learning. The development of two constructions was traced in four adults learning L2 Finnish. Free-response data, collected weekly over a period of 9 months, were used to investigate the produ…
Development of the first PETALO prototype and SiPM studies for neutrino physics
2023
La tomografia per emissió de positrons (PET) és una tècnica no invasiva que proporciona imatges funcionals dels processos metabòlics que ocorren en el cos. Un radiotraçador dopat amb un isòtop emissor de positrons s'injecta en el cos del pacient i s'acumula en l'àrea a estudiar. Allí el positró s'aniquila amb un electró de l'entorn i dona lloc a dues gammes que eixen en direccions oposades. La detecció de les dues gammes en coincidència ens permet inferir la posició de l'anihilació i, per tant, reconstruir imatges tridimensionals o dinàmiques que mostren els processos metabòlics que ocorren en el cos. En aquest treball, discutim en profunditat el potencial del projecte PETALO (Positron Emis…
Understanding prevention measures and tourist behavior in Croatia during the COVID-19 pandemic. A mixed-method approach
2022
This study investigates the adoption of prevention measures in Croatia during the COVID-19 pandemic and its relationship with tourist behavior. The research adopts a mixed-method approach as it examines both practitioners’ and tourists’ viewpoints. A qualitative study was conducted with eight destination service providers, while the quantitative study took place among 333 international tourists during their stay in the country. Results from the qualitative study show that the most frequently employed prevention measures are cleaning and disinfection of customer-use spaces, the use of hand sanitizers, mandatory face masks for employees and guests, and social distancing. Tourism service provi…
Mejorando la comprensión lectora: Desde la intervención metacognitiva en estrategias a la intervención en los procesos ejecutivos de la memoria opera…
2013
Many students may read fluently but have difficulties constructing meaning from texts. Difficulties with reading comprehension have many implications at school. In particular, problems understanding texts interfere with studying and learning from text. Reading comprehension has improved in the last 30 years focusing on intervention programs that work with strategies in which metacog-nition plays a crucial role. However, recent years have seen relevant advances in the study of the relationship between working memory (WM), particularly executive processes, and reading comprehension. In this paper, we present how the last 20 years of our research has evolved regarding metacognitive interventio…
Biografies escolars de professorat de geografia i història en secundària: anàlisi de sis casos
2014
El següent treball parteix de l'anàlisi de sis entrevistes semi-estructurades que recorren la vida formativa i professional de tres professors i tres professores de Geografia i Història de diferents centres de secundària del País Valencià. S'analitzen les biografies docents per a intentar establir quins elements influeixen en elles. A través de l'anàlisi de casos es vol esbrinar si hi ha elements que ajuden a un desenvolupament docent satisfactori o, en canvi, el dificulten. Aquest estudi es fa tenint en compte els referents teòrics que han treballat sobre professorat de Ciències Social i cicles de vida professionals. El que hem pogut observar és que hi ha diferents elements que dificulten …
