Analysis of health communication texts: UK press coverage of debates about assisted dying

2015

Conventionally, social researchers analyse media messages by reading text and coding it. This is time consuming and restricts many studies to small samples. Nowadays very large amounts of text are available in electronic form, offering potential insights into the health messages they contain, but which appear daunting to the analyst with limited resources using conventional methods. I explain and illustrate methods for the computer-assisted analysis of media texts, using specialised software (Wordsmith Tools and Wordstat). These allow the analyst to provide a statistical overview of the key features of texts, to compare them (looking at change over time, for example) and to select illustrat…

Artificial intelligence for affective computing : an emotion recognition case study.

2020

This chapter provides an introduction on the benefits of artificial intelligence (Al) techniques for the field of affective computing, through a case study about emotion recognition via brain (electroencephalography EEG) signals. Readers are first pro-vided with a general description of the field, followed by the main models of human affect, with special emphasis to Russell's circumplex model and the pleasur-arousal-dominance (PAD) model. Finally, an AI-based method for the detection of affect elicited via multimedia stimuli is presented. The method combines both connectivity-and channel-based EEG features with a selection method that considerably reduces the dimensionality of the data and …

"Kaikki haluu olla kingei mut kuka kruunataan" : the linguistic features of English in the Finnish rap artist Cheek's lyrics

2017

Englannin kielen rooli ja vaikutus on suuri useilla eri elämänalueilla tämän päivän Suomessa. Englantia käytetään laajasti esimerkiksi yritysten yhteisenä kielenä sekä median eri osa-alueilla. Englantia pidetään yleisesti modernina ja helposti lähestyttävänä kielenä, jonka osaaminen katsotaan nykyään ennemmin vaatimukseksi kuin lisäeduksi. Cheek on suurta suosiota saavuttanut suomalainen rap-artisti. Cheekin suosio näkyy niin myytyjen levyjen määrässä kuin erilaisten musiikintoistopalveluiden kuten Spotifyn kuuntelutilastoissa. Tämän lisäksi hän on esiintynyt kahdesti loppuunmyydyllä Olympiastadionilla sekä julkaissut omaelämäkerran. Vaikka Cheekin pääasiallinen esiintymiskieli on suomi, kä…

Coupled petrological-geodynamical modeling of a compositionally heterogeneous mantle plume

2018

Abstract Self-consistent geodynamic modeling that includes melting is challenging as the chemistry of the source rocks continuously changes as a result of melt extraction. Here, we describe a new method to study the interaction between physical and chemical processes in an uprising heterogeneous mantle plume by combining a geodynamic code with a thermodynamic modeling approach for magma generation and evolution. We pre-computed hundreds of phase diagrams, each of them for a different chemical system. After melt is extracted, the phase diagram with the closest bulk rock chemistry to the depleted source rock is updated locally. The petrological evolution of rocks is tracked via evolving chemi…

The expanding role of LC-MS in analyzing metabolites and degradation products of food contaminants

2008

Abstract Liquid chromatography-mass spectrometry (LC-MS) has contributed significantly in advancing research in the analysis of metabolites and degradation products of food contaminants. Of particular interest is the comprehensive application of LC-MS to discovery of degradation products and metabolites. This review, covering research published between 2003 and 2008, describes how LC-MS has been used in this field, with the majority of work dealing with target-metabolite analysis and only a small fraction using LC-MS comprehensively. In considering the significance of this topic and the potential interest in it, we briefly describe state-of-the art mass analyzers applied for it (QtrAP, QqTO…
