Diversification in evolutionary arenas - assessment and synthesis
2019
Abstract Understanding how and why rates of evolutionary diversification vary is a central issue in evolutionary biology and ecology. The concept of adaptive radiation has attracted much interest, but is metaphorical and verbal in nature, making it difficult to quantitatively compare different evolutionary lineages or geographic regions. In addition, the causes of evolutionary stasis are relatively neglected. Here we review the central concepts in the evolutionary diversification literature and bring these together by proposing a general framework for estimating rates of diversification and quantifying their underlying dynamics, which can be applied across clades and regions and across spat…
Document papier, document numérique
2003
8 pages; International audience; Les documents sur papier, que l'on croyait un temps menacés, semblent bel et bien perdurer à l'ère du « tout numérique ». Ce support d'un autre âge rempli chaque jour des fonctions et répond à de nombreux usages pour lesquels peu d'utilisateurs préféreraient une version numérique. (Par document numérique, on entend les documents conçus et destinés à être utilisés sur écran.) C'est pour comprendre ce phénomène de résistance au « bureau zéro papier » que cet article tente de répertorier les principales différences entre les deux supports selon quatre points de vue : matériel (propriétés et caractéristiques du support), cognitif (représentation de la structure,…
Applying the integrated trans-contextual model to mathematics activities in the classroom and homework behavior and attainment
2016
The aim of the present study was to test hypotheses of the trans-contextual model. We predicted relations between perceived autonomy support, autonomous motivation toward mathematics learning activities in an educational context, autonomous motivation toward mathematics homework in an out-of-school context, social-cognitive variables and intentions for future engagement in mathematics homework, and mathematics homework outcomes. Secondary school students completed measures of perceived autonomy support from teachers and autonomous motivation for in-class mathematics activities; measures of autonomous motivation, social-cognitive variables, and intentions for out-of-school mathematics homewo…
Improving the Effect of Transcranial Alternating Current Stimulation (tACS): A Systematic Review
2021
With the development of electrical stimulation technology, traditional transcranial alternating current stimulation (tACS) technology has been found to have the drawback of not targeting a specific area accurately. Studies have shown that optimizing the number and position of electrodes during electrical stimulation has a very good effect on enhancing brain stimulation accuracy. At present, an increasing number of laboratories have begun to optimize tACS. However, there has been no study summarizing the optimization methods of tACS. Determining whether different optimization methods are effective and the optimization approach could provide information that could guide future tACS research. …
El carácter transdiagnóstico de las intrusiones mentales/ Transdiagnostic nature of unwanted mental intrusions
2019
Unwanted mental intrusions (UMIs) and their functional consequences had been proposed as symptom dimensions in current cognitive models of Obsessive-Compulsive Disorder (OCD), Body Dysmorphic Disorder (BDD), Illness Anxiety/Hypochondriasis (IA/H) and Eating Disorders (EDs). The main purpose of this doctoral dissertation was to ascertain the transdiagnostic nature of UMIs, above and beyond their specific contents, i.e., obsessional, appearance defects, illness and death, and eating disorders-related. To this end, the Questionnaire of Unpleasant Intrusive Thoughts (QUIT) was designed, and, based on it, four studies were conducted. Studies 1 and 2 examined the transdiagnostic nature of UMIs, b…
Longitudinal Gait Analysis of a Transfemoral Amputee Patient: Single-Case Report from Socket-Type to Osseointegrated Prosthesis
2023
The aim of the present case report was to provide a longitudinal functional assessment of a patient with transfemoral amputation from the preoperative status with socket-type prosthesis to one year after the osseointegration surgery. A 44 years-old male patient was scheduled for osseointegration surgery 17 years after transfemoral amputation. Gait analysis was performed through 15 wearable inertial sensors (MTw Awinda, Xsens) before surgery (patient wearing his standard socket-type prosthesis) and at 3-, 6-, and 12-month follow-ups after osseointegration. ANOVA in Statistical Parametric Mapping was used to assess the changes in amputee and sound limb hip and pelvis kinematics. The gait symm…
La transferencia entre un gran evento deportivo y la marca patrocinadora : la visión del visitante deportivo
2013
La presente Tesis Doctoral se enmarca dentro del turismo de grandes eventos deportivos, considerando la visión del visitante deportivo, entendido éste como excursionista y turista. La revisión de los modelos del comportamiento del turista deportivo y las teorías de patrocinio deportivo, permite el planteamiento de un modelo global de patrocinio deportivo que recoja las principales aportaciones de la literatura. De manera más específica, el eje del modelo se basa en los Modelos de Transferencia aplicados a la transferencia del valor percibido y a la transferencia de la experiencia. Se establece como hipótesis teórica que: Existe una transferencia evento-marca patrocinadora en términos de val…
A transformative value co-creation framework for online services
2019
Purpose: Online offerings for transformative services create value for consumers, although little research examines the process through which these services deliver this value. The purpose of this paper is to develop a comprehensive framework to capture the complexity of the co-creation of transformative value experienced by the consumers of online transformative services. Design/methodology/approach: This paper uses a netnography approach to examine longitudinal data from an online weight management program. In total, this research examines 15,304 posts from 3,149 users, including eight staff users. Findings: Consumers integrate a range of social support resources, from informational suppo…
Wsparcie i radzenie sobie ze stresem jako moderatory związku stresu i jakości życia osób transpłciowych
2018
This study was conducted in order to verify the role of social support and coping strategies as moderators of the relationship between perceived stress and the subjective well-being of transgender people, which is lower than cisgenders’ people. 355 people took part in this study (124 transgender people and 231 cisgender people) between age of 18 and 53. Subjective well-being has been operationalized using the Satisfaction With life Scale SWLS. Measurement of the perceived stress was made using the Perceived Stress Scale PSS-10. Coping strategies were examined using the Mini-COPE inventory. Additionally, two subscales of the Berlin Social Support Scales BSSS were used to measure received and…
Sobre la categoria verbal de temps en búlgar
2022
El sistema verbal búlgar conserva en principi l’esquema antic. La tendència que antigament operà sobre els sistemes eslaus convertint el perfet en un passat general sembla que també va actuar en búlgar, però menà a resultats diferents. Una innovació fou el valor testimonial associat als temps passats, davant del valor neutre dels no-passats. El sistema s’ha enriquit amb altres innovacions basades sobre els valors de perfet: perfets secundaris, formes narratives, mode conclusiu i formes dubitatives. 
 Dediquem aquest treball a trobar una representació d’aquestes formes en fórmules de relacions temporals «E rel R rel S» per tal de veure que les podem considerar «temps» perquè mostren una…
