Light Dark Matter Search with Ionization Signals in XENON1T

2019

We report constraints on light dark matter (DM) models using ionization signals in the XENON1T experiment. We mitigate backgrounds with strong event selections, rather than requiring a scintillation signal, leaving an effective exposure of (22±3) tonne day. Above ∼0.4 keVee, we observe <1 event/(tonne day keVee), which is more than 1000 times lower than in similar searches with other detectors. Despite observing a higher rate at lower energies, no DM or CEvNS detection may be claimed because we cannot model all of our backgrounds. We thus exclude new regions in the parameter spaces for DM-nucleus scattering for DM masses mχ within 3–6 GeV/c2, DM-electron scattering for mχ>30 MeV/c2, a…

iTeXMac: An Integrated TeX Environment for Mac OS X

2004

iTeXMac is an integrated suite of three major components: a text editor detailed in section 2, a PDF viewer detailed in section 3, and a TeX front end detailed in section 4. Some notes on installation are followed by remarks concerning inter-application communication in section 6 for other Mac OS X developers. Finally, the pdfsync feature and the TeX Wrapper are discussed in sections 7 and 8. Since they concern the synchronization between the TeX source and PDF output, and a definition for a shared TeX document structure, both will certainly interest the whole TeX community.

Exploring and Reshaping Learners’ Beliefs About the Usefulness of Corrective Feedback : A Sociocultural Perspective

2016

A number of studies have shown that learners’ beliefs about the usefulness of corrective feedback for improving their L2 (a second or a foreign language) use influences the extent to which learners can utilize that same feedback. It seems, then, that changing some of these beliefs could benefit the L2 learning process. The present article reports on two small-scale studies, both drawing on a sociocultural perspective on the development of beliefs. Changes in learners’ beliefs about corrective feedback were observed both within a period of six months (Case study) and over the course of one research interview (Group study). The studies exemplify how the interplay of one’s own and other’s expe…

Characterizing mood management as need satisfaction: The effects of intrinsic needs on selective exposure and mood repair

2012

This study attempted to (a) extend traditional mood management theory research by investigating the influence of the intrinsic needs for competence and autonomy on selective exposure to video games and (b) test the influence of satisfying these needs on resultant mood repair. An experiment varied satisfaction of competence and autonomy needs using false feedback. Subjects then selected media that varied in level of user demand. Measures of need satisfaction were taken before and after media selection. Results demonstrated that (a) thwarted intrinsic needs significantly predict the choice of video games with different levels of user demand and (b) the satisfaction of these needs predicts enj…

Towards more learning-centred English-medium education: promoting the combination of backward design and community of practice in teacher training

2022

Purpose Teaching in English-medium education (EME) requires mastery of content and ability to teach in a multilingual setting, but also pedagogical expertise and didactic agility. However, there is an apparent lack of proper training of EME teachers, who are typically experts of their field, but not necessarily equipped to design and implement EME. Moreover, there is still an evident gap with respect to understanding how EME teachers turn curricula into actual teaching and students’ learning. By addressing this gap, the present study provides recommendations for EME teacher training. Approach Finland, with its long EME traditions, was the present study’s context. Data saturation, i.e. adequ…

Australian TESOL Teachers’ Cultural Perceptions of Students

2017

ABSTRACTOver the last decade, research in the field of Teaching English to Speakers of Other Languages (TESOL) has increasingly focused on the relationship between culture and learning. Researchers such as Kumaravadivelu (2003) have been vocal in their opposition to the practice of cultural stereotyping. In the current study, Holliday’s (2005) model of Culturism was used as a theoretical basis. Six Australian TESOL teachers were interviewed to determine the nature and extent of the cultural stereotypes that they held, particularly as they pertained to specific learning-related behaviours. A qualitative analysis of the data revealed that teachers most often grouped students in terms of natio…

Kielitutkinto porttina Suomeen ja astinkivenä suomen kieleen

2017

Artikkelissa tarkastellaan inkerilaisten paluumuuttajien kasityksia kielitutkinnosta, joka heidan oli suoritettava saadakseen oleskeluluvan Suomeen niin sanotulla inkerilaisstatuksella. Kielitutkinto oli kaytossa vuosina 2003–2016. Tarkastelun kohteena ovat myos taman kielitutkinnon vaikutukset kielenopiskeluun. Aineistona ovat paluumuuttovalmennukseen osallistuneiden, tutkintoon valmistautuneiden henkiloiden (n = 97) vastaukset kyselyyn, jonka he tekivat ennen kielitutkinnon suorittamista. Aineistoa tarkastellaan sisallonanalyysin keinoin. Aineiston perusteella kielenoppijat tiesivat tutkinnon rakenteesta ja sen suorittamisesta tietokoneella. Suorittajat olivat hyvin tietoisia myos siita, …

Beta- and gamma-melanocortins inhibit lipopolysaccharide induced nitric oxide production in mice brain.

2003

The pro-opiomelanocortin-derived peptide alpha-melanocyte stimulating hormone (alpha-MSH) mediates many diverse physiological actions, including anti-inflammatory and immunomodulatory effects. However, little is known about the physiological roles of the other melanocortins, beta- and gamma-MSH. Here, we investigated the effects of melanocortin peptides in an in vivo neuroinflammation model. Six hours following intracisternal (i.c.) administration of 10 microg lipopolysaccharide (LPS) to mice a five-fold increase in the nitric oxide (NO) level was seen in the animals' brains, when detected by electron paramagnetic resonance (EPR). All tested melanocortins, alpha-, beta-, gamma1- and gamma2-…
