Socio-emotional Problems Experienced by Deaf and Hard of Hearing Students in Ethiopia
2015
This study compares the socio-emotional problems experienced by deaf and hard of hearing (DHH) students with those of hearing students in Ethiopia. The research involved a sample of 103 grade 4 students attending a special school for the deaf, a special class for the deaf and a regular school. Socio-emotional problems were measured using Goodman's self-report measure, the Strengths and Difficulties Questionnaire for children and adolescents. Participants were selected from seven towns in Ethiopia. The results show that, compared to the hearing sample, the DHH students experienced more severe socio-emotional problems across all dimensions, regardless of whether they were in special classes o…
A decomposition approach for multidimensional knapsacks with family-split penalties
2022
The optimization of Multidimensional Knapsacks with Family-Split Penalties has been introduced in the literature as a variant of the more classical Multidimensional Knapsack and Multi-Knapsack problems. This problem deals with a set of items partitioned in families, and when a single item is picked to maximize the utility, then all items in its family must be picked. Items from the same family can be assigned to different knapsacks, and in this situation split penalties are paid. This problem arises in real applications in various fields. This paper proposes a new exact and fast algorithm based on a specific Combinatorial Benders Cuts scheme. An extensive experimental campaign computational…
La importància de la vinculació educativa com a prevenció de la delinqüència juvenil
2011
L’accés al sistema educatiu i la trajectòria al mateix, és un dels elements principals que configuren els factors de risc o de protecció en una societat precària i dualitzada com l’actual. La literatura científica considera fonamental analitzar la relació entre la trajectòria educativa i la vinculació amb la delinqüència juvenil. En aquesta investigació aprofundint en la relació existent entre el procés educatiu i la trajectòria delinqüèncial dels adolescents en conflicte amb la llei. La nostra perspectiva parteix de les hipòtesi següents: a) el fracàs educatiu està relacionat amb la situació de vulnerabilitat i exclusió prèvia de les unitats familiars, com s’ha posat de manifest en nombros…
Depresijas, ruminēšanas un sociālo problēmu risināšanas saistība
2015
Mērķis bija noskaidrot, kāda ir saistība starp depresijas izteiktības pakāpi, ruminatīvas reaģēšanas veidiem un problēmu risināšanas dimensijām. Pētījumā piedalījās 137 studenti (19–36 g.; M = 22,9), tostarp 105 sievietes un 32 vīrieši. Tika izmantota Beka Depresijas aptauja (Beck Depression Inventory II. Beck, Steer & Brown, 1996), Ruminatīvas reaģēšanas aptauja (Ruminative Responses Scale; Treynor, Gonzalez & Susan Nolen-Hoeksema, 2003) un Problēmu risināšanas aptauja (Problem Solving Inventory. Heppner & Petersen, 1982). Rezultāti norāda, ka depresijas izteiktības pakāpe pozitīvi korelē ar visiem trim ruminatīvās reaģēšanas veidiem, bet negatīvi – ar pārliecinātu problēmu risināšanu un p…
Non-standard Problems in an Ordinary Differential Equations Course
2018
International audience; We report first results from a teaching intervention in an ordinary differential equations (ODEs) course for engineering students. Our aim is to challenge traditional approaches to teaching of Existence and Uniqueness Theorems (EUTs) through the design of problems that students cannot solve by applying well-rehearsed techniques or familiar methods. We analyse how the use of nonstandard problems contributes to the development of students' conceptual understanding of EUTs and ODEs.
Análisis de la inclusión educativa a través de indicadores de prevalencia de dificultades de aprendizaje, actitudes del profesorado y condiciones de …
2017
El sistema educativo de Ecuador se encuentra actualmente en un momento de profunda transformación derivada de la reciente aprobación de diferentes leyes nacionales que se han propuesto integrar a este sistema los principios de la educación inclusiva. Formalmente, en Ecuador estas reformas adoptan medidas novedosas que se alinean con las políticas educativas de los sistemas educativos a la vanguardia de la inclusión. Sin embargo, desgraciadamente existe un notable vacío de estudios empíricos que evalúen la situación del sistema educativo en lo referente a educación inclusiva, o que hayan evaluado los resultados que se han producido hasta el momento estas políticas educativas. La presente tes…
Análisis de parámetros fisiológicos durante el pedaleo de brazos en personas con lesión medular, con parálisis cerebral y con ataxia cerebelosa.
2015
Los desórdenes neurológicos generan diferentes grados de afectación física, sensorial y en ocasiones cognitiva, que suele derivar en diferentes grados de discapacidad de la personas que los presentan. El sedentarismo, debido a la disminución de la actividad física habitual y como consecuencia de una falta de oferta de actividad física adaptada e inclusiva, pero también a la falta de información específica sobre el efecto del ejercicio en las personas con desórdenes neurológicos y como prescribirlo, aumenta en gran medida la posibilidad de contraer enfermedades coronarias y otras enfermedades crónicas como la obesidad o la diabetes. Con el objetivo de determinar el efecto del ejercicio de pe…
Inductive inference of recursive functions: complexity bounds
1991
This survey includes principal results on complexity of inductive inference for recursively enumerable classes of total recursive functions. Inductive inference is a process to find an algorithm from sample computations. In the case when the given class of functions is recursively enumerable it is easy to define a natural complexity measure for the inductive inference, namely, the worst-case mindchange number for the first n functions in the given class. Surely, the complexity depends not only on the class, but also on the numbering, i.e. which function is the first, which one is the second, etc. It turns out that, if the result of inference is Goedel number, then complexity of inference ma…
First real–time detection of solar pp neutrinos by Borexino
2014
International audience; Solar neutrinos have been pivotal to the discovery of neutrino flavour oscillations and are a unique tool to probe the reactions that keep the Sun shine. Although most of solar neutrino components have been directly measured, the neutrinos emitted by the keystone pp reaction, in which two protons fuse to make a deuteron, have so far eluded direct detection. The Borexino experiment, an ultra-pure liquid scintillator detector running at the Laboratori Nazionali del Gran Sasso in Italy, has now filled the gap, providing the first direct real time measurement of pp neutrinos and of the solar neutrino luminosity.
Measurement of the spin-dependent structure function g1(x) of the deuteron
1993
We report on the first measurement of the spin-dependent structure function g1d of the deuteron in the deep inelastic scattering of polarised muons off polarised deuterons, in the kinematical range 0.006<x<0.6, 1 GeV2<Q2<30 GeV2. The first moment, Γ1d=sh{phonetic}01 g1d dx=0.023±0.020 (stat.) ± 0.015 (syst.), is smaller than the prediction of the Ellis-Jaffe sum rules. Using earlier measurements of g1p, we infer the first moment of the spin-dependent neutron structure function g1n. The difference Γ1p-Γ1n=0.20 ±0.05 (stat.) ± 0.04 (syst.) agrees with the prediction of the Bjorken sum rule, Γ1p-Γ1n=0.191 ±0.002.
