Entre la ortodoxia y la revolución: Schumpeter y Keynes
2019
Tal vez, Joseph Alois Schumpeter y John Maynard Keynes fueron los economistas que mejor diagnosticaron la naturaleza de los nuevos cambios del capitalismo. ¿Cambios? ¿Qué cambios? ¿Cuándo? A finales del siglo XIX. En este texto se repasan sus principales contribuciones. En el contexto de la crisis, la profunda crisis de la modernidad más reciente. En este artículo se examina y se revisa su distinto compromiso, su compromiso con la realidad política. Sus propuestas fueron no solo un ataque contra la ortodoxia heredada, sino también una alternativa razonable y razonada a la revolución.
Lawrence Kohlberg i el seu llegat
2018
espanolEn esta introduccion al monografico sobre Kohlberg y su obra, se detallan los diferentes proyectos que protagonizo – de investigacion y practica en Psicologia moral– con un amplio equipo de colaboradores, que cristalizo en el famoso «Manual de Medicion del Juicio Moral». Otra iniciativa destacable fueron los encuentros democraticos, donde se votaban los asuntos academicos; asi como la evaluacion exhaustiva de los efectos del programa mencionada, sobre alumnos y docentes, en los talleres de mediciones de entrevistas de juicios morales. Gran impacto causaria por todas partes la teoria de los seis episodios del desarrollo del razonamiento moral, asi como el desarrollo de la empatia, en …
Kieltenopetus vuosiluokilla 1–3: Miten oppilaat siihen suhtautuvat ja mitä tuloksia sillä saavutetaan puolen vuoden opiskelun aikana?
2019

 
 
 As of January 2020, all Finnish pupils are to start their foreign language studies in the first grade. This study examined the effects of early language teaching by comparing pupils in grades 1, 2 and 3. The pupils had started studying English in August 2017 and had all had roughly the same number of English lessons by the time of the study in early 2018. The study examined pupils’ attitudes towards English and studying English as well as how pupils use English in their free time. Pupils also self-assessed their English skills and completed vocabulary and text segmentation tasks. The results show that the pupils had an overall positive attitude towards English and langu…
La motivació del mestre i de l'alumne, des de la pedagogia agustiniana
2019
espanolLa motivacion es uno de los elementos por excelencia de la educacion convirtiendose en la herramienta esencial para conseguir que el alumno o el receptor consiga comprender lo que escucha para alcanzar el tan manido aprendizaje significativo. Encontramos numerosas definiciones que concluyen en decir que en la motivacion influyen tanto factores o variables personales como contextuales. Tratandose, pues, de un elemento esencial en la educacion es importante volver nuestra mirada a los siglos iv y v y, mas concretamente, al pedagogo, teologo, filosofo y maestro de retorica San Agustin de Hipona. Los motivos que nos han llevado a fijarnos en esta figura es por su aportacion al desarrollo…
An Emulator Toolbox to Approximate Radiative Transfer Models with Statistical Learning
2015
Physically-based radiative transfer models (RTMs) help in understanding the processes occurring on the Earth’s surface and their interactions with vegetation and atmosphere. When it comes to studying vegetation properties, RTMs allows us to study light interception by plant canopies and are used in the retrieval of biophysical variables through model inversion. However, advanced RTMs can take a long computational time, which makes them unfeasible in many real applications. To overcome this problem, it has been proposed to substitute RTMs through so-called emulators. Emulators are statistical models that approximate the functioning of RTMs. Emulators are advantageous in real practice because…
Predicting Earthquake-Induced Landslides by Using a Stochastic Modeling Approach: A Case Study of the 2001 El Salvador Coseismic Landslides
2023
In January and February 2001, El Salvador was hit by two strong earthquakes that triggered thousands of landslides, causing 1259 fatalities and extensive damage. The analysis of aerial and SPOT-4 satellite images allowed us to map 6491 coseismic landslides, mainly debris slides and flows that occurred in volcanic epiclastites and pyroclastites. Four different multivariate adaptive regression splines (MARS) models were produced using different predictors and landslide inventories which contain slope failures triggered by an extreme rainfall event in 2009 and those induced by the earthquakes of 2001. In a predictive analysis, three validation scenarios were employed: the first and the second …
Surgical repair of acute Achilles tendon rupture with an end-to-end tendon suture and tendon flap.
2015
Abstract Background Achilles tendon ruptures are becoming more common. Complications after open or minimally invasive surgery are: recurrent rupture (2–8%), wound breakdown, deep infections, granuloma, and fistulas. The authors expose their experience with a personal technique. Materials In 8 patients with acute rupture of Achilles tendon the surgery was performed at least 25 days after trauma. Clinical exam and MR demonstrated in all case a total lesion of tendon. After a posterolateral skin incision the tendon stumps were debrided and suture in end-to-end fashion. A tendon flap was harvested from the proximal part of the tendon, in order to protect and reinforce the suture itself. A plast…
The Retrograde Tibial Nail: presentation and biomechanical evaluation of a new concept in the treatment of distal tibia fractures.
2013
Displaced distal tibia fractures require stable fixation while minimizing secondary damage to the soft tissues by the surgical approach and implants. Antegrade intramedullary nailing has become an alternative to plate osteosynthesis for the treatment of distal metaphyseal fractures over the past two decades. While retrograde intramedullary nailing is a standard procedure in other long bone fractures, only few attempts have been made on retrograde nailing of tibial fractures. The main reasons are difficulties of finding an ideal entry portal and the lack of an ideal implant for retrograde insertion. The Retrograde Tibial Nail (RTN) is a prototype intramedullary implant developed by our group…

Influence of sutures configuration on the strength of tendon-patch joints for rotator cuff tears treatment
2019
Abstract Purpose Massive rotator cuff tears are common in the aging population. The incidence of failed rotator cuff repairs is still quite high, especially in the treatment of full-thickness tears or revision repairs. In this context, natural and synthetic meshes can be used as augmentation scaffolds or as devices to close the gap between a retracted tendon and the bone. The purpose of this work is to evaluate the ultimate tensile strength of different tendon-patch joints in order to consider their use in the treatment of massive cuff tears. Materials and methods Porcine tendons and a synthetic low-density polypropylene mesh have been used. A preliminary study on the tensile strength of te…
