Differential Equations and Continuous-Time Deep Learning (Dagstuhl Seminar 22332)
No full textThis report documents the program and the outcomes of Dagstuhl Seminar 22332 "Differential Equations and Continuous-Time Deep Learning". Neural ordinary-differential equations and similar continuous model architectures have gained interest in recent years, due to the existence of a vast literature in calculus and numerical analysis. Thus, continuous models might lead to architectures with finer control over prior assumptions or theoretical understanding. In this seminar, we have sought to bring together researchers from traditionally disjoint areas - machine learning, numerical analysis, dynamical systems and their "consumers" - to try and develop a joint language about this novel modeling paradigm. Through talks & group discussions, we have identified common interests and we hope that this first seminar is but the first step on a joint journey
Mass Spectrometry Informatics in Systems Biology : Abstracts of the Workshop
No full textMass spectrometry (MS) became a standard tool for identifying metabolites in biological tissues, and metabolomics is slowly acknowledged as a legitimate research discipline for characterizing biological conditions. The computational analyses of metabolomics, however, lag behind compared with the rapid advances in analytical aspects for two reasons. First is the lack of standardized data repository for mass spectra: each research institution is flooded with gigabytes of mass-spectral data from its own analytical groups and cannot host a world-class repository for mass spectra. The second reason is the lack of informatics experts that are fully experienced with spectral analyses. The two barriers must be overcome to establish a publicly free data server for MS analysis in metabolomics as does GenBank in genomics and UniProt in proteomics. The workshop brought together bioinformaticians working on mass spectral analyses in Finland and Japan with the goal to establish a consortium to freely exchange and publicize mass spectra of metabolites measured on various platforms computational tools to analyze spectra spectral knowledge that are computationally predicted from standardized data. This book contains the abstracts of the presentations given in the workshop. The programme of the workshop consisted of oral presentations from Japan and Finland, invited lectures from Steffen Neumann (Leibniz Institute of Plant Biochemistry), Matej Oresic (VTT), Merja Penttila (VTT) and Nicola Zamboni (ETH Zurich) as well as free form discussion among the participants. The event was funded by Academy of Finland (grants 139203 and 118653), Japan Society for the Promotion of Science (JSPS Japan-Finland Bilateral Semi- nar Program 2010) and Department of Computer Science University of Helsinki. We would like to thank all the people contributing to the technical pro- gramme and the sponsors for making the workshop possible.

Land for Exchange and Land Banking in Land Development Projects
No full textThe goal of the study is to find out if the utilisation of land for exchange and so called land banks is a possible way to implement the acquisition of land for public land development projects. Highway and nature conservation projects are examined as examples of these land development projects. The German environment and land banking system has been chosen as a reference for the Finnish environment.
The study is based on comparisons between the domestic and German experiences. The empirical observations of the exchange land acquisition and possibilities to use it are collected through the "Motti" -piloting project (land acquisition for Highway 3). The analyses of the German Landgesellschaft system and the principle of "the mildest means" are giving answers to the questions like why the land banking system is used and on which common requirements of the environment the performance of it is based.
The need for the land exchange and land banks in Germany is concluded to be in the first place a result from the strong position of the principle of 'the mildest means'. The performance of the land banking system is based on the will of society; the demand, profitability and competitiveness of the model; the know-how of the organization; and the long-term and stabilized operations of the organization. The study defines and describes also the principle of a well functioning land bank.
The prospects of implementing the land banking model in Finland are seen to be limited. A separate and independent land banking organization has little chance of success in present circumstances in Finland. The land banking procedure in itself is usable and it can be put into practice for example by a joint land banking function of the Metsähallitus and TE-centres and by an authority and interest group-network supporting the preparation of the wider public land development projects.Tutkimuksen tehtävänä on selvittää, voidaanko yhteiskunnan maankäyttöhankkeiden maanhankintaa Suomessa toteuttaa käyttämällä vastikemaita ja ns. maapankkeja. Maankäyttöhanke-esimerkkeinä tarkastellaan tie- ja luonnonsuojeluhankkeita. Suomalaisen toimintaympäristön vertailukohdaksi on valittu Saksa ja siellä käytössä oleva maapankkijärjestelmä.
Tutkimus perustuu kotimaisten ja saksalaisten kokemusten sekä toimintaympäristöjen erojen tarkasteluun. "Motti"-pilottiprojektin kautta (maanhankinta Valtatie 3:a varten) kerätään empiirisiä havaintoja vastikemaan hankinnasta ja käyttömahdollisuuksista Suomessa. Saksalaisen Landgesellschaft -järjestelmän ja saksalaisen "lievemmän keinon" periaatteen analyysit antavat vastauksia kysymyksiin, miksi Saksassa käytetään maapankkijärjestelmää ja mihin toimintaympäristön yleisiin edellytyksiin sen toimintakyky perustuu.
Vastikemaiden ja maapankkien tarpeen päätellään Saksassa olevan ennen kaikkea seurausta lievemmän keinon periaatteen vahvasta asemasta. Maapankkijärjestelmän toimivuus perustuu tutkimuksen mukaan yhteiskunnan tahtotilaan, toimintamallin kysyntään ja kilpailukykyyn, taloudelliseen kannattavuuteen, maapankkiorganisaation osaamiseen sekä pitkäjänteiseen ja vakiintuneeseen toimintaan. Tutkimus kuvaa myös, millainen on maankäyttöhankkeiden maanhankintaa hyvin tukevan vastikemaapankin toimintaperiaate.
Toimintamallin toteuttamismahdollisuuksista Suomessa todetaan, että erillisellä ja itsenäisellä maapankkiorganisaatiolla ei nykyisissä olosuhteissa ole menestymismahdollisuuksia. Toimintamalli sinänsä on käyttökelpoinen ja toteutettavissa esimerkiksi Metsähallituksen ja TE-keskusten yhteisen maapankkitoiminnon sekä laajempien maankäyttöhankkeiden valmistelua tukevan viranomais- ja sidosryhmäverkoston avulla.reviewe
Article
No full text Harri Heinonen: Football, fandom and flow. On postmodern passions and media-mediated communities The article is an attempt to analyse football fandom within the framework of post-modern culture. In a world where traditional ties have detoriated, fandom fosters a new kind of community of the kind described as neotribalistic. The article argues that sports consumption is not just a passive diversion, but also an active production of cultural meanings. The paper studies the Finnish Everton fans, a group of people (almost exclusively men) who support the English football team Everton, mainly in their homes, in front of their TV sets, where they try to imitate the ‘carnivalesque’ atmosphere of the stadium. The study is based on eight long interviews with representative members of the group, and the data is analysed with a hermeneutical method. The author also participated in gatherings of the Finnish Everton fans. The flow experience, as described by Mihaly Csikszentmihalyi, seems to capture the essence of the experience. In flow, the enjoyment comes from the intensive psychological input in the activity itself, in this case fandom. The pleasurable flow experiences may in certain cases transform into something that features similar to addiction. Fandom can be interpreted as a kind of ‘positive addiction’, where the fans has considerable control over the repetition of the behaviour. Whether Everton fandom is a flow activity or an addiction, it is anyhow an essential activity in the fans' construction of their own good and meaningful life. The role of alcohol as a part of the watching experience is also considered. True fans consume alcohol in front of the TV only for ritual purposes, to strengthen an already pleasurable experience. After the match, or during the fans' yearly gatherings, the drinking can take on the form more typical of Finnish male drinking behaviour. </jats:p
Stroke is predicted by low visuospatial in relation to other intellectual abilities and coronary heart disease by low general intelligence
No full textBACKGROUND: Low intellectual ability is associated with an increased risk of coronary heart disease and stroke. Most studies have used a general intelligence score. We studied whether three different subscores of intellectual ability predict these disorders.METHODS: We studied 2,786 men, born between 1934 and 1944 in Helsinki, Finland, who as conscripts at age 20 underwent an intellectual ability test comprising verbal, visuospatial (analogous to Raven's progressive matrices) and arithmetic reasoning subtests. We ascertained the later occurrence of coronary heart disease and stroke from validated national hospital discharge and death registers.RESULTS: 281 men (10.1%) had experienced a coronary heart disease event and 131 (4.7%) a stroke event. Coronary heart disease was predicted by low scores in all subtests, hazard ratios for each standard deviation (SD) lower score ranging from 1.21 to 1.30 (confidence intervals 1.08 to 1.46). Stroke was predicted by a low visuospatial reasoning score, the corresponding hazard ratio being 1.23 (95% confidence interval 1.04 to 1.46), adjusted for year and age at testing. Adjusted in addition for the two other scores, the hazard ratio was 1.40 (1.10 to 1.79). This hazard ratio was little affected by adjustment for socioeconomic status in childhood and adult life, whereas the same adjustments attenuated the associations between intellectual ability and coronary heart disease. The associations with stroke were also unchanged when adjusted for systolic blood pressure at 20 years and reimbursement for adult antihypertensive medication.CONCLUSIONS: Stroke is predicted by low visuospatial reasoning scores in relation to scores in the two other subtests. This association may be mediated by common underlying causes such as impaired brain development, rather than by mechanisms associated with risk factors shared by stroke and coronary heart disease, such as socio-economic status, hypertension and atherosclerosis
