Enseñanza de las ciencias : revista de investigación y experiencias didácticas
2016
Presentamos los resultados de una investigación enfocada a mejorar el aprendizaje de la geometría y la adquisición de destrezas de razonamiento matemático de estudiantes de 2.º año medio de centros de enseñanza secundaria vulnerables de Chile. Se ha diseñado un experimento de enseñanza, con grupos experimental y control, basado en una unidad de enseñanza, diseñada de acuerdo con los niveles y las fases de Van Hiele, y en un pretest y un postest, para evaluar el cambio en el nivel de razonamiento de los estudiantes derivado de la intervención. Los resultados muestran una diferencia significativa, a favor del grupo experimental, en el desarrollo del nivel de razonamiento de los estudiantes. P…
Crimmigration e tutela della vittima nel reato di tratta di esseri umani : aspetti processuali
2021
Lo strumentario sostanziale e processuale negli ultimi anni ha proiettato la logica del nemico sullo straniero. Una forte crimmigration si è abbinata alla tutela delle vittime dei fenomeni di tratta e di traffico di esseri umani. Guardando in una dimensione integrata di tutela alle dimensioni dei fenomeni e ai legami con la criminalità organizzata, si analizzano le linee di politiche criminali più repressive e le proiezioni processuali della «vulnerabilità». Caratterizzanti e problematici appaiono: la delineazione delle vittime, il complesso radicamento della giurisdizione nazionale, il “doppio gioco” della fattispecie associativa e l’utilizzo della aggravante della transnazionalità, così c…
Disaster vulnerability by demographics?
2020
This article provides a brief overview of the relationship between disaster vulnerability and demographic variables. Population numbers and densities are examined along with using a gender focus as illustrative of individual characteristics. For the most part, people’s and society’s choices create vulnerabilities based on demographics rather than specific demographic characteristics inevitably conferring vulnerability.
Imaging techniques for the vulnerable coronary plaque
2007
The goal of this article is to illustrate the main invasive and noninvasive diagnostic modalities to image the vulnerable coronary plaque, which is responsible for acute coronary syndrome. The main epidemiologic and histological issues are briefly discussed in order to provide an adequate background. Comprehensive coronary atherosclerosis imaging should involve visualization of the entire coronary artery tree and plaque characterization, including three-dimensional morphology, relationship with the lumen, composition, vascular remodelling and presence of inflammation. No single technique provides such a comprehensive description, and no available modality extensively identifies the vulnerab…
Nowhere Home: The Waiting of Vulnerable Child Refugees
2020
In her 2012 documentary Nowhere Home, filmmaker Margreth Olin sheds light on the vulnerabilities and injurabilities of child migrants subjected to prolonged waiting. The documentary shows unaccompanied minors being offered only temporary residence and thus identifies why these irregular migrants can be characterized as ‘particularly vulnerable’ by having their childhoods put on hold. Although the concept is contested, I conceive vulnerability as based on humans’ existential precondition in terms of something bodily and enabling. Due to child refugees’ particular vulnerability, prolonged waiting can violate their inherent dignity, bodily health, life quality and human rights. Therefore, in l…
The impact of the COVID-19 pandemic on human rights of women and girls with disabilities
2021
El presente artículo aborda la situación de especial vulnerabilidad en la que se encuentran las mujeres y niñas con discapacidad, la cual se ha visto agravada en el contexto de la crisis provocada por la pandemia de Covid-19. En efecto, en la primera parte el autor toma nota del actual deterioro de los derechos humanos de las mujeres y niñas con discapacidad, lo cual constituye un desafío para evitar su marginación en términos de doble discriminación. Para afrontar dicho reto, en la segunda parte se pone el énfasis en el papel crucial de la Convención de Naciones Unidas sobre los derechos de las personas con discapacidad como estándar mínimo de protección. En este sentido, en la tercera par…
Decision Support for Disaster Risk Management: Integrating Vulnerabilities into Early-Warning Systems
2014
International audience; Despite the potential of new technologies and the improvements of early-warning systems since the 2004 Tsunami, damage and harm caused by disasters do not stop to increase. There is a clear need for better integrating the fragmented landscape of researchers and practitioners working on different aspects of decision support for disaster risk reduction and response. To demonstrate and discuss the advantages of integrated systems, we will focus in this paper on vulnerabilities and early-warning systems. While vulnerabilities are mostly used to allocate risk management resources (preparedness), early-warning systems are designed to initiate the response phase. Indicator …
Effect of low temperature on starvation-survival of the eel pathogen Vibrio vulnificus biotype 2
1996
At present, no reports exist on the isolation of the eel pathogen Vibrio vulnificus biotype 2 from water samples. Nevertheless, it has recently been demonstrated that this biotype can use water as a route of infection. In the present study, the survival of this pathogen in artificial seawater (ASW) microcosms at different temperatures (25 and 5 degrees C) was investigated during a 50-day period, with biotype 1 as a control, V. vulnificus biotype 2 was able to survive in the culturable state in ASW at 25 degrees C in the free-living form, at least for 50 days, entering into the nonculturable state when exposed to low temperature. In this state, this microorganism survived with reduced rates …

Trafficking and labour exploitation in domestic work and the agricultural sector in Italy
2016
In Italy, as in many European countries, agriculture and domestic work are sectors characterised by high levels of irregular work without contract and with no respect of minimum pay, humane living conditions or access to basic services. Generalised informality however sometimes leads to cases of sever exploitation and outright human trafficking. This report focuses on the conditions that can lead from irregular work to abuse and trafficking in agriculture and domestic work – we question the cultural and economic aspects that make such situations possible. We also review the relevant legislation punishing exploiters and protecting victims with a view of identifying existing gaps and make sug…
