Innovación en la gestión educativa: un estudio empírico
2021
ABSTRACT This paper analyzes the impact of innovative education tools-in this case, based on experimental methodology-on the acquisition of theoretical knowledge among management students. The study incorporates a clear split-sample design using two equivalent, randomly created groups. One group participates in a classroom experiment designed to illustrate the concept of the Phillips Curve, while the other participated in a traditional non-experimental lesson. The experiment is implemented under a strict protocol, while results evaluation is based on the comparison of post-experiment academic performance, which guarantees full anonymity and privacy of decisions. This design analyzes the imp…
Revisiting the “The Breakfast Club”: Testing Different Theoretical Models of Belongingness and Acceptance (and Social Self-Representation)
2021
The current work tests different theoretical models of belongingness and acceptance as fundamental needs for human motivation. In the current study, 372 participants were presented with 52 different items measuring five different theoretical models of belongingness (with a total of 32 items) and three different theoretical models of acceptance (with a total of 20 items). In a first step, Confirmatory Factor Analysis (CFA) failed to provide support for these eight theoretical models. In a second step, we therefore applied Exploratory Factor Analysis yielding three factors, which we interpreted as communicating: (1) Belongingness, (2) Emotion-Acceptance, and (3) Social Self-Representation. In…
La représentation sociale de l'hygiène chez les professionnels de santé : Intérêt du recueil par entretien et de l'analyse discursive des opérateurs …
2009
This study deals with professional representations. The goal is to show the representation of hygiene by health care workers: Nurses (N) and Health Care Aides (HCA). Method follows the BSC (Bases Cognitive Schemes) procedure, explicative interviews substitute to the evaluation task. An analysis of associative words points out that for HCA hygiene is associated with acts linked with corporal hygiene and with two synonymous: no trace, no germ Discussion underlines the interest of this method for professional representations studies and nosocomial infections strength.
Rethinking validity in qualitative sport and exercise psychology research: a realist perspective
2019
Over the last two decades, the relativist approach has significantly shaped debates about the quality and rigour of qualitative research in sport and exercise psychology (SEP). In the absence of any published critiques of relativism in SEP, this paper problematises its central claims with a focus on the most recent contribution offered by Smith and McGannon (2018 Smith, B., & McGannon, K. R. (2018). Developing rigor in qualitative research: Problems and opportunities within sport and exercise psychology. International Review of Sport and Exercise Psychology, 11, 101–121. doi: 10.1080/1750984X.2017.1317357[Taylor & Francis Online], [Web of Science ®], , [Google Scholar]. Developing rigor in …
Efecto pantalla y efecto Sísifo: dos fenómenos didácticos en la resolución de problemas por transferencia analógica
2014
Se presenta un estudio cualitativo, basado en entrevistas semi-estructuradas, de 2 casos que muestran dos fenomenos didacticos de interes en la resolucion de problemas por transferencia analogica. El primero muestra un ‘efecto pantalla’, en el cual el sujeto no puede acceder a la estructura de los problemas a partir de los enunciados. En el segundo caso, el sujeto no logra alcanzar un estado estable de comprension, a pesar de su avance, y por tanto acaba por retroceder a un estado de ausencia de conflicto cognitivo, pero indeseado desde el punto de vista didactico (‘efecto Sisifo’). Se discuten las posibles implicaciones didacticas de estos casos.

A novel microtubule de-stabilizing complementarity-determining region C36L1 peptide displays antitumor activity against melanoma in vitro and in vivo
2015
AbstractShort peptide sequences from complementarity-determining regions (CDRs) of different immunoglobulins may exert anti-infective, immunomodulatory and antitumor activities regardless of the specificity of the original monoclonal antibody (mAb). In this sense, they resemble early molecules of innate immunity. C36L1 was identified as a bioactive light-chain CDR1 peptide by screening 19 conserved CDR sequences targeting murine B16F10-Nex2 melanoma. The 17-amino acid peptide is readily taken up by melanoma cells and acts on microtubules causing depolymerization, stress of the endoplasmic reticulum and intrinsic apoptosis. At low concentrations, C36L1 inhibited migration, invasion and proli…
Nascita e sviluppo della ricerca empirica in campo didattico in Italia
2015
Si ritiene che la ricerca didattica in Italia si sia riavviata intorno al 1950 per il contatto con le scuole statunitensi, per la diffusione delle opere di Dewey e per la nascita dell’Istituto Superiore di Pedagogia della congregazione salesiana. Si ricostruisce il periodo pioneristico della ricerca empirica in campo didattico con il contributo di Calonghi e Visalberghi. Si segnalano alcuni eventi significativi che, intorno alla metà degli anni Settanta, contribuirono all’affermazione della Didattica come scienza dell’insegnamento-apprendimento. Si indicano le principali linee di ricerca empirica in Didattica presenti nell’attuale panorama scientifico italiano.
Rilkean Memories and the Self of a Robot
2019
This paper discusses the concept of Rilkean memories, recently introduced by Mark Rowlands, to analyze the complex intermix of hardware and software related to the self of a robot. The Rilkean memory of an event is related to the trace of that episode left in the body of the individual. It transforms the act of remembering into behavioral and bodily dispositions, thus generating the peculiar behavioral style of the individual, which is at the basis of her autobiographical self. In the case of long-life operating robots, a similar process occurs: the software of the robot has to cope with the changes that happened in the body of the robot because of damaging events in its operational life. T…
Total Absorption Spectroscopy of Fission Fragments Relevant for Reactor Antineutrino Spectra and Decay Heat Calculations
2016
Beta decay of fission products is at the origin of decay heat and antineutrino emission in nuclear reactors. Decay heat represents about 7% of the reactor power during operation and strongly impacts reactor safety. Reactor antineutrino detection is used in several fundamental neutrino physics experiments and it can also be used for reactor monitoring and non-proliferation purposes. 92,93Rb are two fission products of importance in reactor antineutrino spectra and decay heat, but their β-decay properties are not well known. New measurements of 92,93Rb β-decay properties have been performed at the IGISOL facility (Jyväskylä, Finland) using Total Absorption Spectroscopy (TAS). TAS is complemen…
