Geochemistry and volatile content of magmas feeding explosive eruptions at Telica volcano (Nicaragua)

2017

Telica volcano, in north-west Nicaragua, is a young stratovolcano of intermediate magma composition producing frequent Vulcanian to phreatic explosive eruptions. The Telica stratigraphic record also includes examples of (pre)historic sub-Plinian activity. To refine our knowledge of this very active volcano, weanalyzedmajor element composition and volatile content of melt inclusions fromsomestratigraphically significant Telica tephra deposits. These include: (1) the Scoria Telica Superior (STS) deposit (2000 to 200 years Before Present; Volcanic Explosive Index, VEI, of 2–3) and (2) pyroclasts from the post-1970s eruptive cycle (1982; 2011). Based on measurements with nanoscale secondary ion…

Petrological and noble gas features of Lascar and Lastarria volcanoes (Chile): Inferences on plumbing systems and mantle characteristics

2020

Lascar (5592 m a.s.l.) and Lastarria (5697 m a.s.l.) are Chilean active stratovolcanoes located in the Central Volcanic Zone (CVZ; 16°S to 28°S) that have developed on top of a 71 km thick continental crust. Independently of the similarities in their Plinian/Vulcanian eruptive styles, their complex magmatic feeding structures and the origins of their magmatic fluids still necessitate constraints in order to improve the reliability of geochemical monitoring. Here we investigate the petrography, bulk-rock chemistry, and mineral chemistry in products from the 1986–1993 explosive eruptive cycle at Lascar and from several Holocene eruptive sequences at Lastarria. These data are integrated with m…

Chapter 16 Pre-eruptive vapour and its role in controlling eruption style and longevity at Soufrière Hills Volcano

2014

We use volatiles in melt inclusions and nominally anhydrous phenocrysts, with volcanic gas flux and composition, and textural analysis of mafic inclusions to estimate the mass of exsolved vapour prior to eruption at Soufriere Hills Volcano (SHV). Pre-eruptive andesite coexists with exsolved vapour comprising 1.6–2.4 wt% of the bulk magma. The water content of orthopyroxenes indicates a zone of magma storage at pressures of approximately 200–300 MPa, whereas melt inclusions have equilibrated at shallower pressures. Inclusions containing >3 wt% H2O are enriched in CO2, suggesting flushing with CO2-rich gases. Intruding mafic magma contains >8 wt% H2O at 200–300 MPa. Rapid quenching is accompa…

MANIPULATION OF OBJECTS AS INTEGRATION ACTIVITY

2016

The visual disability assumes, in the processes of teaching and learning, a particular connotation for the specificity that over the years the vision in the overall structure of knowledge has had. The whole western tradition on the knowledge stood on a "oculocentric" vision of knowledge. The view has always been considered the “sense for excellence". An educational activity, therefore, that emphasizes and promotes strategies of inclusion / integration of students with visual impairment is significant and essential to the whole class group. We present here an experimentation with primary school children: in a closed bag, there are objects of everyday life: every time a child extracts an obje…

Global connectedness in higher education : student voices on the value of cross-cultural learning dialogue

2015

The study explores how sense of global connectedness can be enhanced by creating opportunities for cross-cultural dialogue in higher education. Thematic analysis of randomly selected 15 learning journals, students’ reflections on their learning during an international seminar was used to identify students’ significant learning experiences. The results emphasise the added value of diversity (geographical, disciplinary, cultural and social) among students, faculty and invited presenters for creating meaningful learning. Furthermore, they suggest that designing an integrated approach of contents, contexts and activities for critical engagement in global dialogue and knowledge generation in hig…

Classroom behavioural climate in inclusive education – a study on secondary students’ perceptions

2021

Previous studies pointed out that dealing with difficult behaviour is perceived by teachers as a major challenge in inclusive settings. However, research on the students' perception of the classroom behavioural climate (CBC) is rare. Therefore, this study aims to examine students’ perceptions of CBC and to identify predictors of CBC as well as associated variables. The sample consists of 650 German students from secondary schools (5th-9th grade) of whom 83 students are diagnosed with special educational needs (SEN). CBC was measured via four subscales (‘students’ possibilities to study and concentrating on teaching’, ‘disruptive behaviour’, ‘physical and psychological safety’ and ‘caring fo…

Social Inclusion Challenges for Different Society Groups in Latvia

2021

Latvia has been receiving critical remarks from international institutions in regard to high level of social inequality of various groups in the society. Statistical data indicate that the society of Latvia has to address serious challenges in social inclusion, including several aspects in health care. The aim of the paper is to propose possible solutions for social inclusion of different society groups, especially in relation to health care aspects and including application of life-long-learning for health care for several society groups. Research approach to the problem: analysis of data obtained in representative survey 9280 respondents: health condition self-evaluation analysis by regio…

Proximity violence against women refugees and migrants in Sicily. Operators’ testimonies

2019

The research presented in this chapter intended illustrating the practices im-plemented to foster inclusion of and support to migrants above all, female refugees/asylum seekers hosted by reception centres in Sicily . At the same time, it sought to outline some of the limits the reception system presents when it comes to supporting victims of proximity vio-lence. A description of these practices and identification of the limits became, therefore, the two-fold purpose of this investigative project (PRoximity On VIolence: Defence and Equity) fouded by European Community Rights, Equality and Citizenship Programme -2014-2020). To carry out the research two methodological choices had to be made: …
