Development of microfluidics for sorting of carbon nanotubes
2018
Sorting of carbon nanotubes by their chirality is the current bottleneck in the way to their broad employment based on their exceptional electronic and optical properties. Despite the extensive effort, there is no known method, which would result in really pure chirality ensembles. Previously reported sorting protocols result in enrichment rather than in sorting, alter electronic structure, and suffer from low yield. This is mostly due to the statistical approach, where the nanotubes with mixed chiralities are treated as a set. In this thesis, we propose a new sorting technique based on nanotube-by-nanotube compartmelization, characterization, and sorting in a continuously running droplet-b…
Potential for adaptation to climate change: family-level variation in fitness-related traits and their responses to heat waves in a snail population.
2017
Background On-going global climate change poses a serious threat for natural populations unless they are able to evolutionarily adapt to changing environmental conditions (e.g. increasing average temperatures, occurrence of extreme weather events). A prerequisite for evolutionary change is within-population heritable genetic variation in traits subject to selection. In relation to climate change, mainly phenological traits as well as heat and desiccation resistance have been examined for such variation. Therefore, it is important to investigate adaptive potential under climate change conditions across a broader range of traits. This is especially true for life-history traits and defences ag…
The effect of spatial and temporal scale on camouflage in North African rodents
2022
Abstract Background matching, a common form of camouflage, is a widespread anti-predator adaptation that hinders detection or recognition by increasing the resemblance of prey to its environment. However, the natural environment is complex and both spatially and temporally variable, which constrains effective background matching as an anti-predator strategy. Here, using remote sensing data (publicly available satellite imagery), we investigated how variation of habitat parameters predicts background matching in 16 Sahara–Sahel rodent species across spatial and temporal scales. All fur colour parameters (hue, saturation and brightness) strongly matched the respective habitats of the differen…

Kulttuuriset ennakkoluulot sosiaalityön ongelmanmäärittelyn resursseina : esimerkkinä kunniaan liittyvä väkivalta
2023
Esitys perustuu vielä työn alla olevaan artikkelikäsikirjoitukseen, jonka olen kirjoittanut pro gradu -tutkielmani ”Kunnia, etnisyys ja kulttuuri. Sosiaalityöntekijöiden käsityksiä kunniaan liittyvästä väkivallasta” (Elfving 2017) pohjalta. Tutkielman tarkoituksena oli selvittää miten sosiaalityöntekijät määrittelevät ongelmia kunniaan liittyvän väkivallan tapauksissa. Aineistoni perusteella sosiaalityöntekijät käyttävät kulttuurisia ennakkoluuloja ongelmanmäärittelyn resursseina. Väkivaltaisuuden katsotaan olevan kiinteä osa ”muslimikulttuuria” ja sen perinteitä. Väkivallan mahdollistaa naisen huono asema. Asiakkaan muslimitausta erotetaan suomalaisuudesta tarkkarajaisesti ja sillä selitet…
Luokassa luokassa? : miten vanhempien status-tekijät vaikuttavat lasten toissijaiseen sosialisaatioon ja luokittumiseen ensimmäisinä kouluvuosina?
2011
Bourdieu presented his theory of class and class reproduction and I'm interested in founding out how does socialization process affect this dynamic process in an egalitarian western country. Does educational system determine the future of the children by renewing the class structure or does the equal opportunities to succeed academically invalidate the reproduction cycle. By using longitudinal Alkuportaat-data (N=2258) from years 2006-2008 a co-variate analysis and a hierarchical modelling were made. Mathematical problem-solving and fluency in mother tongue were used as indicators for successful secondary socialization. The class structure is presented by parents' socio-economic status, deg…
Narodnost Neuvostoliiton musiikkipolitiikassa 1930-luvulla
2018
Artikkeli käsittelee yhden keskeisimmän sosialistista realismia määrittäneen alakäsitteen, narodnostin (suom. ”kansallisuus” tai ”kansanomaisuus, kansanomainen henki, kansallinen omaleimaisuus”), historiaa ja käyttöönottoa Neuvostoliiton musiikkipolitiikassa 1930-luvulla. Tutkimuksellisena lähestymistapana sovelletaan käsitehistorian ja diskurssintutkimuksen periaatteita kiinnittäen huomiota erityisesti poliittisesti merkityksellisten käsitteiden historiallisuuteen. Narodnost oli käsite, jonka avulla perusteltiin taidemusiikin kaanonin ja erityisesti romantiikan aikakauden musiikin sopivuus sosialistiseen yhteiskuntaan. Käsitteen avulla vallankumouksellisuuden ja edistyksellisyyden diskurss…
Durabilità, in ambiente fortemente basico, delle fibre di PET provenienti dalla raccolta differenziata
2012
La sperimentazione esposta nella presente pubblicazione tratta dell’impiego di fibre di PET, ricavate dal semplice taglio di contenitori per bevande secondo un procedimento brevettato, nel rinforzo di calcestruzzi destinati anche a impieghi strutturali. Descrive le caratteristiche geometriche delle fibre e ne indaga la durabilità in condizioni severe che potrebbero presentarsi in un’applicazione pratica quale una pavimentazione esterna. A tal fine campioni costituiti da gruppi di fibre sono stati immersi per tredici giorni a 65°C in soluzioni a differente concentrazione di NaOH (0,103 M e 1,75 M). In particolare la soluzione a concentrazione 0,103 M di NaOH (pH=13) simula la basicità della …
The Export Strategy and SMEs Employment Resilience During Slump Periods
2021
Abstract The Spanish economy was the most hit by the Great Recession. It suffered a greater decrease in the gross domestic product (GDP) (affecting especially internal demand). However, it suffered a greater increase in exports (the so-called Spanish “miracle”). Particularly, Spanish SMEs incorporation into exports has been spectacular since 2008. Further, this has coincided with a huge increase in unemployment. Therefore, our main objective is to investigate the moderating role of exports in job destruction associated with recessive contexts of domestic demand using Spanish manufacturing SMEs as a case study. We obtain for SMEs that export participation helps compensate for the decrease in…
