A model of degassing for Stromboli volcano
2010
International audience; A better understanding of degassing processes at open-vent basaltic volcanoes requires collection of new datasets of H2O–CO2–SO2 volcanic gas plume compositions, which acquisition has long been hampered by technical limitations. Here, we use the MultiGAS technique to provide the best-documented record of gas plume discharges from Stromboli volcano to date. We show that Stromboli's gases are dominated by H2O (48–98 mol%; mean, 80%), and by CO2 (2–50 mol%; mean, 17%) and SO2 (0.2–14 mol%; mean, 3%). The significant temporal variability in our dataset reflects the dynamic nature of degassing process during Strombolian activity; which we explore by interpreting our gas m…
A CO2-gas precursor to the March 2015 Villarrica volcano eruption
2017
We present here the first volcanic gas compositional time-series taken prior to a paroxysmal eruption of Villarrica volcano (Chile). Our gas plume observations were obtained using a fully autonomous Multi-component Gas Analyser System (Multi-GAS) in the 3 month-long phase of escalating volcanic activity that culminated into the 3 March 2015 paroxysm, the largest since 1985. Our results demonstrate a temporal evolution of volcanic plume composition, from low CO$_2$/SO$_2$ ratios (0.65-2.7) during November 2014-January 2015 to CO$_2$/SO$_2$ ratios up to ≈ 9 then after. The H$_2$O/CO$_2$ ratio simultaneously declined to <38 in the same temporal interval. We use results of volatile saturatio…
Wybory niekonkurencyjne w Polsce na poziomie lokalnym – wstępne oceny
2020
Artykuł podejmuje problem obsadzania mandatów bez głosowania w wyborach do rad gmin w gminach liczących do 20 tys. mieszkańców. W stosunku do wyborów z 2014 r. liczba takich przypadków wzrosła w 2018 r. o 77%. Wydaje się, że obowiązujące prawo wyborcze, w szczególności art. 418 § 1 (podział gmin na jednomandatowe okręgi wyborcze), art. 434 § 1 i 2 (zasady organizacji wyborów w przypadku zgłoszenia liczby kandydatów równej liczbie mandatów do obsadzenia) i art. 478 § 2 (tryb zgłaszania kandydatów na wójta lub burmistrza) Kodeksu wyborczego, w połączeniu z uwarunkowaniami lokalnej rywalizacji wyborczej, może sprzyjać powstawaniu zjawiska niekonkurencyjnych wyborów, które skutkują m.in. spadki…
Dialogioppiminen ryhmä- ja yksilötasoilla hoitotyön kontekstissa
2000
Artikkelissa dialogioppimista on tulkittu hoitotyön oppimisen ja opettamisen erilaisissa käytänteissä. Käsitys dialogista perustuu Bahtinin puheen teoriaan, jossa näkökulmien vastakkaisuutta pidetään dialogin syntymisen ehtona. Käsitys oppimisesta perustuu kontekstuaaliseen näkemykseen, jossa oppimisen kohteeksi rajataan arkitodellisuus ja sieltä nousevat ongelmat. Koska arjen ristiriitaiset käytänteet kiinnittyvät erilaisiin ajattelu- ja toimintamalleihin, puheesta on etsitty historiallisia ääniä, vakiintuneiksi muodostuneita hoitamisen ja oppimisen muotoja. Tarkoituksena on ollut selvittää, millaisten dialogien avulla näistä erilaisista äänistä rakennetaan jaettua ja yksilöllistä tietämys…
A qualitative study of pre-service teachers’ experienced benefits and concerns of using motivational interaction in practice after a training course
2022
This is a pre-print of a published study: Renko, E., Koski-Jännes, A., Absetz, P. et al. A qualitative study of pre-service teachers’ experienced benefits and concerns of using motivational interaction in practice after a training course. Humanit Soc Sci Commun 9, 458 (2022). https://doi.org/10.1057/s41599-022-01484-y Despite its positive effects on physical activity promotion, motivational style of interaction by health professionals is not easily taken up, as shown by meta-analyses of training courses. The concerns professionals experience for taking up the novel skills remain an open question. Preservice physical education teachers were offered a 16-hour training course on motivational i…
From ‘intercultural-washing’ to meaningful intercultural education: Revisiting higher education practice
2021
This is the first special issue that JPHE hosts—and could there be a more suitable forum for an issue dedicated to exploring and encouraging a critical dialogue around transformative intercultural communication teaching practices in higher education (HE)? What has led us to engage with the theme of making intercultural education meaningful is a shared observation that there seems to be an increasing disconnect between recent developments in intercultural communication theory and practice. With so much critique published over the years, we are perplexed as to why traditional notions of culture still prevail not only in mainstream intercultural communication research but also in institutional…
CP-vammaisten oppilaiden ja henkilökunnan vuorovaikutus konduktiivisen opetuksen ryhmässä
2017
Tiainen, A. 2016. CP-vammaisten oppilaiden ja henkilökunnan vuorovaikutus konduktiivisen opetuksen ryhmässä. Liikuntatieteellinen tiedekunta, Jyväskylän yliopisto, fysioterapian pro gradu -tutkielma, 37s., 8 liitettä. Pro gradu –työ on osa syksyllä 2013 käynnistettyä Jyväskylän yliopiston Toimintakykyä edistävän ohjauksen (TEO) projektia. Pro gradu –työn tavoitteena oli selvittää, millaista on vuorovaikutus erityiskoulun konduktiivisen opetuksen (CE) pienryhmässä. Balesin (1951) mukaan pienryhmä koostuu toisiinsa vuorovaikutuksessa olevista ihmisistä, jotka ovat tietoisia toisistaan ja tuntevat olevansa ryhmä. Tärkeä piirre pienryhmälle on, että sen jäsenet ovat keskenään vuorovaikutuksessa…

Challenging Transmission Modes of Teaching in Science Classrooms : Enhancing Learner-Centredness through Dialogicity
2017
There is an ongoing reform towards more inquiry-based teaching in school curriculum policy in South Africa. Reform towards more inquiry-based approaches is already integrated in pre-service teacher education programmes. As inquiry-based approaches have been gaining momentum worldwide, there is an increasing concern that dialogic interaction in classroom communication is being neglected. This is especially within teacher-orchestrated classroom interactions that should foster greater learner centredness and thus authentic scientific inquiry. In learner-centred teaching approaches, student contributions should be explicitly taken into account as part of classroom interactions in science. Learn…
