Intervención educativa en el alumnado con discapacidad auditiva
Treball final de Grau en Mestre o Mestra d'Educació Primària. Codi: MP1040. Curs acadèmic 2014-2015El trabajo se divide básicamente en cinco apartados: en primer lugar, un marco teórico en el que
se tratan aspectos tan importantes como: dificultades que presenta el alumno con hipoacusia,
modalidades de lenguaje, tipos de hipoacusias, protocolo de actuación con los mismos. En un
segundo lugar, tomando como referencia el marco teórico, se realizará un análisis de la realidad
del centro con estos niños, es decir, elementos personales que lo forman, su organización,
programas y servicios, relaciones entre el centro familia y comunidad. Una tercera parte donde se
analizará la respuesta educativa del centro, cambios organizativos curriculares (metodológicos,
adaptaciones curriculares..). Una cuarta parte que se correspondería con una respuesta a nivel de
aula ( información sobre los recursos tecnológicos FM, intervención preventiva en el aula de
infantil .
Se sigue con una recogida de datos sobre casos individuales analizando sus historias educativas
y qué adaptaciones de acceso y /o curriculares, recursos personales y materiales tienen a su
disposición.
Finalmente se proponen mejoras para la aceptación del alumno sordo en el grupo clase y se
concluye con la valoración de la experiencia
A framework for epidemic spreading in multiplex networks of metapopulations
We propose a theoretical framework for the study of epidemics in structured
metapopulations, with heterogeneous agents, subjected to recurrent mobility
patterns. We propose to represent the heterogeneity in the composition of the
metapopulations as layers in a multiplex network, where nodes would correspond
to geographical areas and layers account for the mobility patterns of agents of
the same class. We analyze both the classical Susceptible-Infected-Susceptible
and the Susceptible-Infected-Removed epidemic models within this framework, and
compare macroscopic and microscopic indicators of the spreading process with
extensive Monte Carlo simulations. Our results are in excellent agreement with
the simulations. We also derive an exact expression of the epidemic threshold
on this general framework revealing a non-trivial dependence on the mobility
parameter. Finally, we use this new formalism to address the spread of diseases
in real cities, specifically in the city of Medellin, Colombia, whose
population is divided into six socio-economic classes, each one identified with
a layer in this multiplex formalism.Comment: 13 pages, 11 figure
Recycling Oxacillin Residues from Environmental Waste into Graphene Quantum Dots
Of great concern are the residual antibiotics from dirt that can be found in farm soil and wastewater. This kind of emerging pollutant into engineered nanomaterials is riveting. This work proposes the elimination and transformation of a beta-lactam antibiotic, oxacillin, from environmental waste to graphene quantum dots (GQDs). Two protocols were followed in which the use of ethylenediamine (EDA) in the transformation leads to GQDs with excellent optical properties. Therefore, two types of GQDs were synthesized in a Teflon-lined stainless autoclave by a thermal procedure using oxacillin in the absence and presence of EDA. The ensuing e-GQDs from oxacillin and EDA display a stronger fluorescence emission in comparison to those synthesized without EDA (o-GQDs). The combination of Kaiser test analyses, infrared (IR) and Raman measurements revealed the presence of oxygen-containing groups and primary amines at the edges of the graphitic nanolayer for e-GQDs. This straightforward strategy brings hope and opens a new interest in waste recycling by means of extracting residual contaminants from the environment for their further transformation into adequate non-toxic graphitic nanomaterials with potential applications

Clinical and microbiological diagnosis of oral candidiasis
Introduction: Candidiasis or oral candidiasis is the most frequent mucocutaneous mycosis of the oral cavity. It is
produced by the genus Candida, which is found in the oral cavity of 53% of the general population as a common
commensal organism. One hundred and fifty species have been isolated in the oral cavity, and 80% of the isolates
correspond to Candida albicans, which can colonize the oral cavity alone or in combination with other species.
Transformation from commensal organism to pathogen depends on the intervention of different predisposing factors
that modify the microenvironment of the oral cavity and favor the appearance of opportunistic infection.
The present study offers a literature review on the diagnosis of oral candidiasis, with the purpose of establishing
when complementary microbiological techniques for the diagnosis of oral candidiasis should be used, and which
techniques are most commonly employed in routine clinical practice in order to establish a definitive diagnosis.
Materials and methods: A Medline-PubMed, Scopus and Cochrane search was made covering the last 10 years.
Results: The diagnosis of oral candidiasis is fundamentally clinical. Microbiological techniques are used when
the clinical diagnosis needs to be confirmed, for establishing a differential diagnosis with other diseases, and in
cases characterized by resistance to antifungal drugs. Biopsies in turn are indicated in patients with hyperplastic
candidiasis. Staining (10% KOH) and culture (Sabouraud dextrose agar) are the methods most commonly used
for diagnosing primary candidiasis. Identification of the individual species of Candida is usually carried out with
CHROMagar Candida®. For the diagnosis of invasive candidiasis, and in cases requiring differentiation between
C. albicans and C. dubliniensis, use is made of immunological and genetic techniques such as ELISA and PCR
Psychological Aspects, Attitudes and Behaviour Related to the Practice of Sexting: A Systematic Review of the Existent Literature
AbstractThere are few studies about the sexting phenomenon, and most of them are of a descriptive nature. However, not many of them relate this practice with psychological or social constructs.Our aim is to explore what psychological aspects, attitudes and behaviour have been associated with the practice of sexting. To achieve this, we have made a systematic review of the existent literature.One remarkable evolution in these studies is that their amount has grown, and more attention has been paid to the above mentioned issues.If we take a general view to the results, we can distinguish a clear ‘criminalizing’ tendency, since most of the investigation lines have been oriented to relate sexting with health risk behaviour. One of the main conclusions to emphasize is that despite the risks of this practice, young people continue doing it.We find it convenient to look closer at this psychological framework to obtain relevant data for the future
