Tässä artikkelissa tarkastellaan eri kieli-ideologioiden—eli arkisten kieltä ja sen puhujia koskevien uskomusten—rooleja opiskelijoiden identiteetin rakentamisessa ja neuvotteluissa kansainvälistyvän korkeakoulutuksen kontekstissa. Englanninkielisten opiskelijoiden lisääntyvän monimuotoisuuden myötä kieli-ideologioita on tutkittu mahdollisena opiskelijoiden välisen epätasa-arvon rakentajana. Analysoin kahta fokusryhmäkeskustelua, joiden osallistujat ovat erään suomalaisen yliopiston kansainvälisten englanninkielisten maisteriohjelmien opiskelijoita. Tutkin opiskelijoiden puhetta kriittisen diskursiivisen psykologian avulla tarkoituksenani ymmärtää mahdollisia yhtymäkohtia kieli-ideologioide…
Extraction of lapachol from Tabebuia avellanedae wood with supercritical CO2: an alternative to Soxhlet extraction?
2003
The solubility of lapachol in supercritical CO2 was determined at 40°C and pressures between 90 and 210 bar. Supercritical fluid extraction of lapachol and some related compounds by CO2 from Tabebuia avellanedae wood is compared to Soxhlet extraction with different solvents. A standard macroscale (100-200 g wood) and a microscale (~10 mg wood) experimental setup are described and their results are compared. The latter involved direct spectrophotometric quantification in a high-pressure autoclave with an integrated optical path and a magnetic stirrer, fitted directly into a commercial spectrophotometer. The relative amount of lapachol extracted by supercritical CO2 at 40°C and 200 bar was ab…

Valorization of waste solvents through supercritical water gasification
2017
The supercritical water gasification of various organic species belonging to the groups of organic acids, aldehydes, ketones, alcohols and phenols, has been studied as a possible waste disposal method for polluted water stream produced in industries and laboratories. Gasification has been investigated using a 200 cm3 down flow reactor working continuously at 24 MPa and 660 °C. Supercritical water gasification (SCWG) is effective for the syngas production at very high conversion rate for all the species investigates, but phenol. Phenol, when mixed with other species, has an inhibitory effect of the radical chain gasification mechanism that dramatically reduced the gasification performance. …
Afterword: Anthropology, the non-human and the ontological turn
2017
This afterword has two aims: a short critical assessment of the so-called “ontological turn” in the human sciences, and a critical commentary on some of the issues raised by the articles gathered in this special issue on the anthropology of the non-human. I argue that, as underlined by all the contributors, the question of how we think about the nature of politics and power relations is crucial for any evaluation of this new “turn”. An examination of the treatment given by Descola, Latour, Viveiros de Castro and their followers to the issue of power must account for the differences among these theoretical approaches and the political implications that can be draw from each of them. However,…

Del present imperfecte i dels futurs de probabilitat, o entorn de la filologia, la lingüística, l'anàlisi crítica del discurs i les ciències de la co…
2005
What is the aim today of talking about philology, either in absolute terms or related to other concepts such as linguistics or language sciences? On the one hand, it seems unfair to resort to metaphors that pair (traditional) philology and (textual) necrophilia. On the other hand, turning our back on the reality is not the appropriate response to current problems: a more applied training (in the professional field) is needed, and (in the scientific context) the frontiers should be pushed back, because the old ones are obsolete and in need of reappraisal. Faced with a past and a present that are inevitably imperfect, this article is a reflection on the chances of a future in which philology …
'Different' and 'distinct' as markers of otherness: A corpus-driven study of the (re)creation of privilege in high standard hotels.
2020
The present study seeks to offer an understanding of how high-end hotel websites produce privilege, creating a sense of belonging and entitlement for their 4/5-star guests. The experience of tourism is intrinsically linked to embracing otherness, and as a reflection of this, hotel websites offer a characterization of cultural otherness in an attempt to make it resonate with the potential expectations of a socioeconomically privileged client. The study considers the question of what elements of experience of otherness the website will address, relying on a Critical Discourse Analysis perspective and drawing on Bourdieu's notion of habitus as related to lifestyle, difference and distinction. …
A twofold commodification of 'place' in hotel websites and its consequences for the discursive creation of a tourist identity.
2016
Tourism is a global cultural industry and one of the world’s largest international trades (Thurlow & Jaworski, 2011). As far as tourism is understood as an agent and channel of globalisation (Pritchard & Jaworski, 2005), it makes sense to investigate it from a critical perspective and analyse how its discourse shapes the tourist experience. The aim of this study is to explore ways in which hotel websites project a place identity for the hotel and, in doing so, for the town or city in which the hotel is located. I will ask how, and in what ways, this representation relies on socio-cultural conventions, which in turn may influence the discursive construction of the social actor “tourist”. Usi…
Comparisons of two diaphragm ultrasound-teaching programs: a multicenter randomized controlled educational study
2019
Abstract Background This study aims to ascertain whether (1) an educational program is sufficient to achieve adequate Diaphragm Ultrasound (DUS) assessments on healthy volunteers and (2) combining a video tutorial with a practical session is more effective in making learners capable to obtain accurate DUS measurements, as opposed to sole video tutorial. Results We enrolledstep 1: 172 volunteers naïve to ultrasound. After watching a video tutorial, a questionnaire was administered and considered to be passed when at least 70% of the questions were correctly answered. Course participants who passed the theoretical test were randomized to either intervention or control group. Learners randomiz…
