Helping lecturers address and formulate teaching challenges: an exploratory study
2018
International audience; In this paper we present an exploratory study on the kind of questions or difficulties lecturers point out at the beginning of an educational course – to be addressed in it. These questions happen to be very general and are poorly connected to the knowledge to be taught. We suggest a twofold interpretation of this phenomenon. On the one hand, and in the line of the didactic transposition theory, teachers do not allow themselves to raise questions about the knowledge that is supposed to be their main field of expertise. On the other hand, the prevailing institutional pedagogy does not provide teachers with a fruitful enough conceptual frame to formulate this kind of q…

Sleep habits in children affected by autism spectrum disorders: A preliminary case-control study
2017
Introduction: The core of autism spectrum disorders (ASD) consists of alterations of neurological functions that affect the typical developmental trajectory leading to deficits in social interaction and non-verbal behaviors. In general, ASD is diagnosed at age three and many other frequent neurological signs may be present, such as sleep disorders. The aim of study is evaluating sleep habits in a sample of ASD children. Material and methods: The study population consists of 65 ASD children (43 males and 22 females), aged between 2 and 11 years (mean 5.73 ± 2.39 years). The control group consists of 114 children with typical development (68 males and 46 females), aged between 3 and 10 years …
Adaptive and Creative Problem-Projects in the Teaching of Science. Description of the Methodology and Appreciation of the Students Involved
2019
En este artículo se describe la metodología que se ha denominado Aprendizaje Basadoen Problemas-Proyectos Adaptativos y Creativos (ABPac), utilizando como ejemplo algunos de losproyectos realizados en el centro concertado Jesús-María de Burgos durante diez años, entre 2006y 2016, con alumnos de Secundaria Obligatoria y Bachillerato. Esta metodología sugiere una aten-ción a la diversidad del alumnado considerando sus necesidades e inquietudes. Además, se analizacuantitativamente el resultado de la encuesta de percepción realizada a 73 individuos involucradosen esta metodología cuando ya ha transcurrido un tiempo de madurez y se encuentran finalizandosus carreras o con estas ya finalizadas.

Avoiding strange attractors in efficient parametric families of iterative methods for solving nonlinear problems
2019
[EN] Searching zeros of nonlinear functions often employs iterative procedures. In this paper, we construct several families of iterative methods with memory from one without memory, that is, we have increased the order of convergence without adding new functional evaluations. The main aim of this manuscript yields in the advantage that the use of real multidimensional dynamics gives us to decide among the different classes designed and, afterwards, to select its most stable members. Moreover, we have found some elements of the family whose behavior includes strange attractors of different kinds that must be avoided in practice. In this sense, Feigenbaum diagrams have resulted an extremely …
Parents' causal attributions concerning their children's academic achievement
2007
Katja Natale seurasi väitöstutkimuksessaan vanhempien lastensa koulumenestystä koskevien kausaaliattribuutioiden eli syyselitysten muotoutumista lasten siirtyessä esikoulusta kouluun. Hän tutki kuinka tärkeinä vanhemmat pitivät kykyä, yrityksen määrää, tehtävien vaikeustasoa ja lapsen saamaa ohjausta selittämässä lasten onnistumista ja epäonnistumista koulussa. - Koulunsa aloittavien lasten vanhempia voisi neuvoa viestimään lapsilleen, että heillä on kykyjä onnistua haastavissakin koulutehtävissä. Tällainen viesti vaikuttaa positiivisesti lasten koulutaitojen kehitykseen ja minäkuvan muuttumiseen realistisemmaksi, Natale suosittaa.Onnistuminen kyvykkyyttä, epäonnistuminen yrityksen puutetta…
The mediating role of vulnerability factors in the association between attachment and internalizing/externalizing problems
2015
Recent research indicates that secure attachment is a protective factor against the development of internalizing / externalizing behavioral problems (Laible et al., 2000), while the role of insecure attachment is more controversial, raising the question of potential mediating variables (Brumariu & Kerns, 2010). In literature it emerges how Blatt’s two-configurational model (self-definition and relatedness) correlates on the one hand with the attachment (Luyten & Blatt, 2011; Mikulincer & Shaver, 2007), and on the other with the internalizing / externalizing spectrum (e.g. Campos, Besser, Morgado, & Blatt, 2014). This research has explored the mediation effects of relatedness (dependency) an…
Autoestima, percepción de estrés y ánimo depresivo en grupos de riesgo.
2001
Los grupos de riesgo se caracterizan por una mayor vulnerabilidad a desarrollar problemas psicológicos y sociales y, por tanto, suelen ser los destinatarios prioritarios de muchas de las intervenciones realizadas por los trabajadores sociales. En este sentido, en esta investigación se analizan tres variables psicológicas que pueden estar relacionadas con la mayor vulnerabilidad de los diversos grupos de riesgo- En concreto, se comparan las variables de autoestima, percepción de estrés y ánimo depresivo en personas que manifiestan un problema de salud física como es la hipertensión (n=30) y en personas con un problema de tipo psicosocial como es el consumo abusivo de alcohol (n=47) en relaci…
Work stress and health problems of professional drivers: A hazardous formula for their safety outcomes
2018
BackgroundSeveral empirical studies have shown that professional drivers are a vulnerable occupational group, usually exposed to environmental stressors and adverse work conditions. Furthermore, recent studies have associated work-related stress with negative job performances and adverse health outcomes within this occupational group, including cardiovascular diseases and unsafe vehicle operation.ObjectiveThe aim of this study was to describe the working conditions and the health status of this occupational group, and to evaluate the association between the Demand–Control model of job stress and their self-reported health and safety outcomes.MethodsA pooled sample of 3,665 Colombian profess…
Il Polar prima del Polar: il poliziesco italo-americano tra fine Ottocento e gli anni Trenta del Novecento
2018
Tra la fine dell’Ottocento e gli anni Trenta del Novecento, alcuni Italiani immigrati negli Stati Uniti – quali, fra gli altri, Bernardino Ciambelli, Italo Stanco, Garibaldi Marto Lapolla, Louis Forgione, nonché il sodalizio letterario costituito da Michael Fiaschetti e Prosper Buranelli – si sono cimentati nel genere del poliziesco con alcuni testi che, partendo da alcune delle caratteristiche tipiche del Mystery, quali la serializzazione e l’incardinamento della fabula in uno specifico contesto urbano, insieme ad alcuni degli elementi caratteriali dei personaggi dell’Hard boiled non perdono mai di vista la peculiare ‘missione’ di denuncia politica, economica e sociale. Facendo del problem…
