Double Marginalized Lives as Woman and as Refugee: Syrian Female Refugees in Ankara
2020
Este tesis establece cómo las refugiadas sirias son social, económica, cultural, étnica y sexualmente marginadas y lo que piensan acerca de los eventos en curso, su estado y los pasos que el gobierno y las ONGs han tomado hasta ahora para dar soluciones a la invisibilización de las mujeres en la esfera pública. Para ello, he llevado a cabo esta investigación en los suburbios de Ankara con un grupo de refugiadas sirias que están socialmente excluidas como “mujer'” y como “refugiada” y con un grupo de mujeres locales. La atención se centrará en la relación entre los discursos producidos en la sociedad de acogida y la exclusión social de las refugiadas sirias. Cabe señalar que la fuente de los…
Contribución de las cuestiones sociocientíficas al desarrollo del pensamiento crítico (II): Ejemplos
2013
En este trabajo se presentan ejemplos de cuestiones socio-científicas CSC en diferentes campos de la ciencia que pueden contribuir al desarrollo del pensamiento crítico en la educación científica, mostrando competencias críticas involucradas.
Contribution of socio-scientific issues to development of critical thinking (I): Introduction
2013
En este trabajo intentamos justificar, basándonos en la didáctica y en la historia de las ciencias, que las cuestiones socio-científicas pueden contribuir a desarrollar el pensamiento crítico de los estudiantes. Estas consideraciones sobre la historia de la ciencia se pueden transformar en cuestiones socio-científicas (CSC), que se pueden usar en las clases de ciencias.
Impact of the Extraction Method on the Chemical Composition and Antioxidant Potency of Rosmarinus officinalis L. Extracts
2023
Rosmarinus officinalis L. is a dietary source that produces polyphenols as secondary metabolites. These natural compounds with potent antioxidant abilities are increasingly recommended as a supplement to inhibit oxidative stress. In the current work, we evaluated the impact of the extraction method on the chemical composition of R. officinalis extract, especially on the content of carnosic (CA) and rosmarinic (RA) acids using UPLC-MS-DAD as well as on their antioxidant potency. Four extracts of Tunisian rosemary were obtained from non-conventional extraction techniques:ultrasound-assisted extraction (UAE),supercritical extraction (SFE) and UAE and SFE combined ((UAE-SFE(I), UAE-SFE(II)). Th…
Living the urban challenge : sustainable development and social sustainability in two southern megacities
2007
Kehitysmaiden nopea kaupungistuminen ja miljoonakaupunkien voimakas kasvu luovat haasteita kestävään kehitykseen tähtäävälle suunnittelulle. Kansainvälisissä kehitysohjelmissa on pyritty turvaamaan suurkaupunkien taloudelliset ja ympäristölliset tavoitteet. Kestävän kehityksen sosiaalinen ulottuvuus on usein rajattu kaupunkien tarjoamiin sosiaalipalveluihin.- Ympäristön säilyttäminen tuleville sukupolville ei onnistu vain talouteen, ympäristöön ja palveluihin kohdistuvilla teknisillä toimilla. Tämä johtuu etelän suurkaupungeille tyypillisestä räikeästä sosiaalisesta eriarvoisuudesta. Suurkaupunkien suunnittelussa tulisi analysoida sellaisia sosiaalisia haasteita, jotka heikentävät kaupunkie…
Service-learning in physical education teacher education: towards a critical and inclusive perspective
2020
The purpose of this study was to analyse the impact of service-learning (SL) in physical education teacher education students (PETEs). The PETEs (n = 169) completed one of the editions of a SL program carried out between 2015–2018. This program consisted of designing and leading motor game sessions to facilitate the inclusion of 116 children with special educational needs (SEN). The program was based on Kolb’s learning stages to promote reflection and critical thinking. Reflective journals were used as an instrument to gather information from their experiences. These data were analysed qualitatively through a multiphase approach, initial open-coding and axial coding, using NVivo (10) softwa…
Acetic acid leaching of neodymium magnets and iron separation by simple oxidative precipitation
2022
Neodymium-iron-boron (NdFeB) has become the most prominent permanent magnet alloy, with a wide variety of applications and an ever-increasing demand. Their recycling is important for securing the supply of critical raw materials used in their manufacturing. The use of organic acids such as acetic acid has been of recent interest for the recycling of waste NdFeB magnets. Despite achieving good leaching efficiencies, the published literature has not properly investigated the effects of key factors influencing the acetic acid leaching process and their respective interactions, which has lead to conflicting findings as to what conditions are optimal. The present work goes to show that no such o…

Victims, villains or organized community? : discrimination, social exclusion and empowerment in the media representation of urban poverty : case of b…
2012
The purpose of this thesis is to study the media representation of urban poverty in a developing country context, focusing specifically on the connections between media representation and social exclusion. The theoretical-methodological basis of this work draws from critical cultural studies and sociological media research, specifically from the theoretical assumptions of critical discourse analysis about media representation. The premise is the constructionist view that the media does not directly reflect the reality of urban poverty, but constructs journalist reproductions of it from a particular perspective and in a certain social context. Media representation of the subordinated groups …
