  • Karisto, Antti (2007)
    The paper offers a generational viewpoint to population ageing with the example of the Finnish baby boomers. The paper first outlines the special characteristics of the Finnish baby boomers as a cohort and a generation. Secondly, it goes on to shortly describe their life courses in order to build an understanding on what their future life might be. Finally, the paper discusses the coming retirement years of the boomer generation in terms of the emergence of the “third age”, i.e. a life period between working age and old age proper. The concept of the third age may offer an alternative viewpoint to population ageing, which so often is discussed only in terms of increasing pension expenditures and care burden.

    This paper describes scientific, technical and legal work done on the creation of the linguistic infrastructure for the Nordic and Baltic countries. The paper describes the research on assessment of the language technology support for languages of Baltic and Nordic countries, on establishing language resource sharing infrastructure and collection and description of linguistic resources. We present improvements necessary to ensure usability and interoperability of language resources, discuss IPR issues related to intellectual property rights for complex resources, describe extension of infrastructure through integration of language-resource specific repositories. Work on treebanks, wordnets, terminology resources and finite-state technology is described in more details. Finally, our approach on ensuring sustainability of infrastructure is discussed.

    In order to maintain indigenous, self-regenerating tree populations in urban woodlands, it is essential to identify factors affecting the survival of tree seedlings and saplings. In densely populated areas, intensive recreational use may cause considerable wear of the vegetation and soil, and decrease the total number of saplings. At the same time trees, high stones and other structural elements in a woodland patch can act as natural barriers and give shelter against wear. Hence, we hypothesised that with an increasing amount of wear, a greater proportion of tree saplings survive, and is thus found, close to these natural barriers. We tested this hypothesis with observational data, and described the microhabitat associations of different sapling species in detail to define the most favourable or unfavourable microhabitats. We recorded the microhabitats of saplings and randomly chosen points in 30 medium-fertile Picea abies dominant woodlands in Helsinki and the surroundings, Finland. The description included location in relation to physical objects (stones, trees, topography, etc.), other saplings, vegetation and canopy. We then compared the sapling microhabitats to those available (the random points). Our results suggest that the microhabitat associations of saplings change with increasing wear: Sorbus aucuparia, Populus tremula, Rhamnus frangula, Picea abies and Acer platanoides saplings grew more often close to natural barriers (obstacles X30 cm high excluding other saplings), the first three showing a statistically significant response to wear in logistic regression models. The saplings were able to grow in a variety of microhabitats, but the species also differed in their microhabitat associations. In general, saplings grew in groups, and in worn sites the grouping was more pronounced. With increasing wear the saplings associated more positively with trees, canopy cover and lush vegetation.

    Our two-person “flood basalt task force” (authors Arto Luttinen and Jussi Heinonen) of the Finnish Museum of Natural History (LUOMUS) spent three weeks in Mozambican countryside collecting samples of the little-studied flood basalt formations of the Jurassic ~180 Ma Karoo large igneous province. The expedition was related to the recently launched MARZ (Magmatism in the Africa- Antarctica Rift Zone) project that is funded by the Academy of Finland. Fieldwork was carried out within three provinces, Tete, Sofala, and Manica in cooperation with Professor Daud Jamal, Dr. Estêvão Sumburane, Mr. Teofilo Gove (all from the Eduardo Mondlane University in Maputo), and Dr. António Alface (Direcção Nacional de Geologia, Tete). During the field campaign, we took lodging in towns and villages and also camped on the forest savannah, and were greatly impressed by the friendliness and helpfulness of the local people. Despite the tropical conditions, the quality of the bedrock outcrops was surprisingly good and we were able to collect ~150 rock samples, well above our initial expectations. The samples will be analysed for major and trace elements, Sr and Nd isotopes, and selected samples will be used for Ar- Ar plagioclase and U-Pb zircon dating. Our samples are from areas that have not been previously studied in detail and the results hopefully will shed light on the mysteries related to the origin of Karoo and other flood basalt provinces.

    Human bocaviruses (HBoVs) 1-4 are recently discovered, antigenically similar parvoviruses. We examined the hypothesis that the antigenic similarity of these viruses could give rise to clinically and diagnostically important immunological interactions. IgG and IgM EIAs as well as qPCR were used to study similar to 2000 sera collected from infancy to early adolescence at 3-6-month intervals from 109 children whose symptoms were recorded. We found that HBoV1-4-specific seroprevalences at age 6 years were 80%, 48%, 10%, and 0%, respectively. HBoV1 infections resulted in significantly weaker IgG responses among children who had pre-existing HBoV2 IgG, and vice versa. Furthermore, we documented a complete absence of virus type-specific immune responses in six viremic children who had pre-existing IgG for another bocavirus, indicating that not all HBoV infections can be diagnosed serologically. Our results strongly indicate that interactions between consecutive HBoV infections affect HBoV immunity via a phenomenon called "original antigenic sin", cross-protection, or both; however, without evident clinical consequences but with important ramifications for the serodiagnosis of HBoV infections. Serological data is likely to underestimate human exposure to these viruses.

    The vibrations produced by the cardiovascular system that are coupled to the precordium can be noninvasively detected using accelerometers. This technique is called seismocardiography. Although clinical applications have been proposed for seismocardiography, the physiology underlying the signal is still not clear. The relationship of seismocardiograms of on the back-to-front axis and cardiac events is fairly well known. However, the 3-D seismocardiograms detectable with modern accelerometers have not been quantified in terms of cardiac cycle events. A major reason for this might be the degree of intersubject variability observed in 3-D seismocardiograms. We present a method to quantify 3-D seismocardiography in terms of cardiac cycle events. First, cardiac cycle events are identified from the seismocardiograms, and then, assigned a number based on the location in which the corresponding event was found. 396 cardiac cycle events from 9 healthy subjects and 120 cardiac cycle events from patients suffering from atrial flutter were analyzed. Despite the weak intersubject correlation of the waveforms (0.05, 0.27, and 0.15 for the x-, y-, and z-axes, respectively), the present method managed to find latent similarities in the seismocardiograms of healthy subjects. We observed that in healthy subjects the distribution of cardiac cycle event coordinates was centered on specific locations. These locations were different in patients with atrial flutter. The results suggest that spatial distribution of seismocardiographic cardiac cycle events might be used to discriminate healthy individuals and those with a failing heart.

    This article describes a novel experimental setup that combines X-ray microtomography (XMT) scans with in situ X-ray scattering experiments in a laboratory setting. Combining these two methods allows the characterization of both the micrometre-scale morphology and the crystallographic properties of the sample without removing it from the setup. Precise control of the position of the sample allows an accurate choice of the scattering beam path through the sample and facilitates the performance of X-ray scattering experiments on submillimetre-sized samples. With the present setup, a voxel size of less than 0.5 mm is achievable in the XMT images, and scattering experiments can be carried out with a beam size of approximately 200 200 mm. The potential of this setup is illustrated with the analysis of micrometeorite crystal structure and diffraction tomographic imaging of a silver behenate phantom as example applications.
