Assertions conjecturales dans deux œuvres de Toivo Pekkanen
1997
Tämä tutkielma on deskriptiivis-kontrastiivinen tutkimus suomen ja ranskan välillä. Tarkoituksena oli etsiä arvelemisen ilmaisimet Toivo Pekkasen kahdesta teoksesta ja niiden ranskannoksista. Arvelevat väitteet edustavat episteemistä modaliteettia, joka antaa ilmaukselle merkityksen ’mahdollinen’ tai ’todennäköinen’. Vertailun avulla olen pyrkinyt löytämään ne lingvistiset keinot, joilla ranskassa ilmaistaan episteemistä modaliteettia. Tutkimukseni kohteena olivat ranskan futuuri, suomen synteettinen potentiaali ja analyyttistä potentiaalia edustavat epävarmuuden adverbit ’ehkä’, ’kai’, ’kenties’ sekä arvelua ilmaiseva konditionaali. Synteettisellä potentiaalilla tarkoitetaan suomen potenti…

Microscopic Insights Into the Formation of Methanesulfonic Acid–Methylamine–Ammonia Particles Under Acid-Rich Conditions
2022
Understanding the microscopic mechanisms of new particle formation under acid-rich conditions is of significance in atmospheric science. Using quantum chemistry calculations, we investigated the microscopic formation mechanism of methanesulfonic acid (MSA)–methylamine (MA)–ammonia (NH3) clusters. We focused on the binary (MSA)2n-(MA)n and ternary (MSA)3n-(MA)n-(NH3)n, (n = 1–4) systems which contain more acid than base molecules. We found that the lowest-energy isomers in each system possess considerable thermodynamic and dynamic stabilities. In studied cluster structures, all bases are protonated, and they form stable ion pairs with MSA, which contribute to the charge transfer and the stab…
Modeling atmospheric aging of small-scale wood combustion emissions: distinguishing causal effects from non-causal associations
2022
Small-scale wood combustion is a significant source of particulate emissions. Atmospheric transformation of wood combustion emissions is a complex process involving multiple compounds interacting simultaneously. Thus, an advanced methodology is needed to study the process in order to gain a deeper understanding of the emissions. In this study, we are introducing a methodology for simplifying this complex process by detecting dependencies of observed compounds based on a measured dataset. A statistical model was fitted to describe the evolution of combustion emissions with a system of differential equations derived from the measured data. The performance of the model was evaluated using simu…
Saturation vapor pressure characterization of selected low-volatility organic compounds using a residence time chamber
2023
Saturation vapor pressure (psat) is an important thermodynamic property regulating the gas-to-particle partitioning of organic compounds in the atmosphere. Low-volatility organic compounds (LVOCs), with sufficiently low psat values, primarily stay in the particle phase and contribute to aerosol formation. Obtaining accurate information on the psat of LVOCs requires volatility measurements performed at temperatures relevant to atmospheric aerosol formation. Here, we present an isothermal evaporation method using a residence time chamber to measure psat for dry single-compound nanoparticles at 295 K. Our method is able to characterize organic compounds with psat spanning from 10−8 to 10−4 Pa …
Affective Estrangement and Ecological Destruction in TV Crime Series Fortitude
2020
Koistinen and Mäntymäki examine how graphic violence evokes affect in the context of ecological destruction in the UK-produced TV crime fiction series Fortitude (2015–17). They argue that the series mobilises generic exchange by incorporating speculative elements into a traditional crime narrative structure, thereby creating space for affective estrangement. They show how the amalgamation of violence, ecological destruction and affect serves as an entrance into socioecological critique with a strong cautionary element through the negotiation between the human and nonhuman and the ethics of violence. Theoretically, the chapter relies on Sara Ahmed’s view of affect as social processes produce…

Agenttipohjaisten suunnittelumenetelmien vertailu
2004
Agenttipohjainen ohjelmistotuotanto edustaa yhtä uusimmista paradigmoista ohjelmistotuotannon alueella. Agentilla tarkoitetaan ohjelmiston osaa, joka kykenee itsenäiseen ja älykkääseen toimintaan käyttäjänsä puolesta saavuttaakseen sille suunnitellut tavoitteet. Agenttipohjaisten järjestelmien suunnitteluun on kehitetty varsin kirjava joukko menetelmiä. Tutkielman päätavoitteena on kuvata, analysoida ja vertailla agenttipohjaisia menetelmiä sen selvittämiseksi, mitä yhtäläisyyksiä ja eroja niiden käsitteissä, malleissa ja prosesseissa. Tutkielma on otteeltaan käsitteellisteoreettinen ja aihetta lähestytään agentteja, agenttipohjaisia menetelmiä ja menetelmien vertailua käsittelevän kirjalli…

What makes the difference : PIAAC as a resource for understanding the problem-solving skills of Europe's higher-education adults
2019
The ever-evolving technological landscape is challenging adults' problem-solving skills. The central goal of higher education (HE) is to guarantee a high level of know-how, which is in line with the changing demands of technology at work and in everyday life. This study builds on European data from the Programme for the International Assessment of Adult Competencies (PIAAC) to understand adults' (N = 53,407) skills for solving problems in technology-rich environments. The study provides insight into the socio-demographic, work-related, and everyday factors that are associated with a strong and a weak problem-solving performance. The results indicate that HE adults stand out from adults with…
