Attitudes towards English variations : Finnish high school students’ views on American English, British English and Australian English
2010
Englanti on maailman kieli, joka kuuluu jokapäiväiseen suomalaiseen katukuvaan ja englannin eri variaatioita esiintyy ympäri maailmaa. Ihmiset muodostavat omat käsityksensä ja asenteensa näitä variaatioita kohtaan henkilökohtaisten kokemustensa ja maailmankuvansa kautta. Aiemmissa tämän tieteenalan tutkimuksissa on keskitytty pääasiassa asenteisiin, joita suomalaisilla on eri kielistä yleisesti. Aiemmat tutkimukset ovat keskittyneet yksittäisten ihmisten välisiin mielipide-eroihin, eikä niinkään sukupuolten välisiin asenne-eroihin. Tässä tutkimuksessa selvitettiin sitä, millaisia erilaisia asenteita suomalaisilla lukion kolmasluokkalaisilla oppilailla on englannin kielen eri variaatioita k…
Quechua influence in the Andean Spanish in Cuentos y leyendas populares de la Argentina
2017
En la actualidad, no podemos obviar la existencia de un español con rasgos indígenas en Hispanoamérica. En particular, en Argentina encontramos el denominado Español andino en el norte del país, en concreto en el noroeste argentino. En esta zona observamos el contacto entre el español de Argentina y el quechua. Aunque está demostrado el contacto indígena del español en esta zona, todavía se discute hasta qué punto existe esa influencia en aspectos que vayan más allá del léxico. Por ello, en este trabajo vamos, en primer lugar, a situar geográficamente esta variante del español indígena, para después poder investigar en qué niveles lingüísticos hay influencia del quechua y, finalmente, anali…
Multiplex Amplicon Quantification (MAQ), a fast and efficient method for the simultaneous detection of copy number alterations in neuroblastoma
2010
Abstract Background Cancer genomes display characteristic patterns of chromosomal imbalances, often with diagnostic and prognostic relevance. Therefore assays for genome-wide copy number screening and simultaneous detection of copy number alterations in specific chromosomal regions are of increasing importance in the diagnostic work-up of tumors. Results We tested the performance of Multiplex Amplicon Quantification, a newly developed low-cost, closed-tube and high-throughput PCR-based technique for detection of copy number alterations in regions with prognostic relevance for neuroblastoma. Comparison with array CGH and the established Multiplex Ligation-dependent Probe Amplification method…
Case report: absence of the right piriformis muscle in a woman
2018
We report a very rare case of a unilaterally absent piriformis muscle in a 60 year old woman. Accompanying variations comprised a common gluteal artery (instead of two distinct superior and inferior gluteal arteries), and an absent gemellus inferior muscle. The contralateral left side showed a normally developed piriformis muscle. In hominoids, the piriformis is constant, but is regularly missing in several other vertebrates. The piriformis muscle is an anatomical landmark for ultrasound investigations and ultrasound-guided interventions in the deep gluteal region such as a superior gluteal nerve block or even a sacral plexus block, also for any surgical approach such as total hip arthropla…
Slight variations in components ratio affect odor pleasantness of a blending mixture
2009
International audience; Odors rely mainly on the perception of odorants mixtures but are commonly perceived as single undivided entities; nevertheless, the processes involved remain poorly explored. It has been reported that perceptual blending, based on configural olfactory processing, can lead odorant mixtures to give rise to an emergent odor quality not present in the components. Furthermore, very slight variations (just noticeable differences, jnd) in components concentrations were shown to be sufficient to modify the odor quality of a blending mixture. In the present study, we set out to examine whether jnd in components concentrations could also affect the odor pleasantness of a blend…
Determinants of the interannual relationships between remote sensed photosynthetic activity and rainfall in tropical Africa
2007
International audience; The response of photosynthetic activity to interannual rainfall variations in Africa South of the Sahara is examined using 20 years (1981-2000) of Normalised Difference Vegetation Index (NDVI) AVHRR data. Linear correlations and regressions were computed between annual NDVI and annual rainfall at a 0.5° latitude/longitude resolution, based on two gridded precipitation datasets (Climate Prediction Center Merged Analysis of Precipitation [CMAP] and Climatic Research Unit [CRU]). The spatial patterns were then examined to detect how they relate to the mean annual rainfall amounts, land-cover types as from the Global Land Cover 2000 data set, soil properties and soil typ…

Situational factors shape moral judgements in the trolley dilemma in Eastern, Southern and Western countries in a culturally diverse sample
2022
The study of moral judgements often centres on moral dilemmas in which options consistent with deontological perspectives (that is, emphasizing rules, individual rights and duties) are in conflict with options consistent with utilitarian judgements (that is, following the greater good based on consequences). Greene et al. (2009) showed that psychological and situational factors (for example, the intent of the agent or the presence of physical contact between the agent and the victim) can play an important role in moral dilemma judgements (for example, the trolley problem). Our knowledge is limited concerning both the universality of these effects outside the United States and the impact of …
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…
