"Hold on! Apua tulossa." : English practices among Finnish Twitter users

2015

Lähes kaikki suomalaiset osaavat englantia ja sitä pidetään suuressa arvossa niin tieteen, tekniikan, kaupan kuin populaarikulttuurin aloilla. Internetissä englanti on ollut aina tärkeä valtakieli, vaikkakin on nähtävissä, että pienemmät kielet saavat enemmän tilaa erityisesti sosiaalisen median suosion ansiosta. Sosiaalinen media on etenevässä määrin tärkeä osa myös suomalaisten jokapäiväistä elämää. Vuonna 2006 Yhdysvalloissa perustettu Twitter on sosiaalisen median sovellus, joka kerää suosiota jatkuvasti ympäri maailmaa. Suomalaisten käyttäjien määrä kasvaa koko ajan ja Twitter on nykyään näkyvä osa niin suomalaisessa mediassa kuin arkipäivän keskusteluissa. Englannin kieleen liittyviä …

A Linguistic journey to the border

2011

Language is a powerful tool. Linguistic creativity provides the means to new ways of knowing, thinking, and being, and allows a new set of dialogues to emerge. This paper illuminates how Guillermo Gómez-Peña, a Chicano performance artist, writer, activist and educator uses language to do just this. In this paper, I will specifically focus on Gómez-Peña’s use of monolingual English and Spanish, as well as his application of code-mixed dialogue and illustrate how his linguistic innovation reflects his position on Border Culture. peerReviewed

"Me ollaan mukana tässä experimentissä" : lingvististiska resurser och språkpraktiker i tvåspråkiga ungdomssamtal i Haparanda, Stockholm och Helsingf…

2017

The thesis explores bilingual adolescents’ language use, linguistic resources, and language practices in interaction at three junior high schools in Haparanda, a Swedish town on the country’s northeastern border with Finland. A comparison is also made with interaction among bilingual adolescents at two Sweden-Finnish junior high schools in Stockholm and at one Swedish-speaking junior high school in Helsinki. The aim of the study is to increase our knowledge of bilingual adolescents’ interaction practices and language repertoires, i.e. translanguaging, in interaction. The primary data consists of close to eleven hours of video- and audio-recorded informal group and pair conversations. The da…

Groupware architecture for requirements processes in new product development

1999

An organization's ability to create successful products depends on how extensively it collects, analyzes and utilizes requirements information in its product development. Recent advances in groupware technologies allow such information to be shared more effectively in distributed organizations; thus, these technologies hold considerable potential as means of shortening the cycle time and improving the quality of requirements processes. This paper addresses issues in the design and implementation of groupware-supported requirements processes by drawing on experiences from large-scale industrial development projects within Nokia. The primary contribution of the paper is the conceptual design …

Supercontinuum Generation and Intermodal Four-Wave Mixing in a Step-Index Few-Mode Fibre

2019

International audience; The complex spatiotemporal dynamics of nonlinear light propagation in multimode fibers (MMFs) has recently witnessed a renewed interest because of their experimental realization in emerging key areas of laser physics and fiber optics [1]. Specifically, MMFs have a number of linear and nonlinear optical properties that make them very attractive to investigate new spatiotemporal effects fundamentally different from standard single-mode fibers. These include the observation of multimode solitons [2], intermodal four-wave mixing (FWM) [3], geometric parametric instabilities [4], spatial beam self-cleaning [5], and the generation of supercontinuum (SC) light when pumping …

Benefits and Drawbacks of A High Frequency Gan Zvzcps Converter

2017

This paper presents the benefits and drawbacks of replacing the traditional Si Mosfets transistors with enhancement mode GaN transistors in a Half-Bridge Zero Voltage and Zero Current Switching Power Switching (ZVZCPS) converter. This type of converters is usually used as Electronic Power Converters (EPC) for telecommunication satellites travelling-wave tube amplifiers (TWTAs). In this study, firstly the converter is theoretically analysed, obtaining its operation, losses and efficiency equations. From these equations, optimizations maps based on the main system parameters are obtained. These optimization maps are the key to quantify the potential benefits of GaN transistors in this type of…

Application of Ge Nanowire for Two-Input Bistable Nanoelectromechanical Switch

2013

Recently, several research groups presented bistable two-terminal nanoelectromechanical switches based on individual single-clamped active element. All presented devices had one input electrode. Similar devices having two or more input electrodes have not been yet investigated. In this work we present the two-input bistable controlled nanoelectromechanical switch based on an individual single-clamped Ge nanowire. The switch is realised using in-situ SEM technique and operating due to balancing of electrostatic, adhesion and elastic forces. The operation conditions of the device are investigated and presented. The advantages and drawbacks of the device are discussed. DOI: http://dx.doi.org/1…

Design, Synthesis and Characterization of a Visible-Light-Sensitive Molecular Switch and Its PEGylation Towards a Self-Assembling Molecule.

2022

HBDI-like chromophores represent a novel set of biomimetic switches mimicking the fluorophore of the green fluorescent protein that are currently studied with the hope to expand the molecular switch/motor toolbox. However, until now members capable of absorbing visible light in their neutral (i. e. non-anionic) form have not been reported. In this contribution we report the preparation of an HBDI-like chromophore based on a 3-phenylbenzofulvene scaffold capable of absorbing blue light and photoisomerizing on the picosecond timescale. More specifically, we show that double-bond photoisomerization occurs in both the E-to-Z and Z-to-E directions and that these can be controlled by irradiating …

Incidence, prevalence and clinical correlates of antidepressant-emergent mania in bipolar depression: a systematic review and meta-analysis.

2018

Background: Treatment-emergent mania (TEM) represents a common phenomenon inconsistently reported across primary studies, warranting further assessment. Methods: A systematic review and meta-analysis following the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) and Meta-Analysis of Observational Studies in Epidemiology (MOOSE) guidelines were conducted. Major electronic databases were searched from inception to May 2017 to assess the incidence and prevalence rates and clinical features associated with manic switch among bipolar depressed patients receiving antidepressants, using meta-regression and subgroup analysis. Results: Overall, 10 098 depressed patients wit…
