    In scholarship, nationalism has been found to be an integral ingredient of any sense of nationhood. In everyday public use, nationalism is used as a term of disapproval. The stubborn discursive border between the two uses of the concept of nationalism evokes questions about the historical preconditions of creating an ism concept based on the roots 'nation' or 'national'. In the period often called 'the age of nationalism', from the French Revolution to the First World War, nationhood was essentialized in ways that did not allow nations to be explained as constructions of any ism. 'Nationalism' gained popularity from the 1890s onwards as a critical concept directed at ideas and actions that broke against what was seen as the legitimate role of a nation. Defining the role of nations and nationhood took place in a series of political contests utilizing the concept of nationalism. Debates on Europe and 'European society' created one of the contexts of these contests. In current scholarly discussion on the idea of a European society, the critique of 'methodological nationalism' has been targeted at the nation-state-bound notion of society. However, in much of policy-oriented research and policy planning, the references to nationalism only contain views and actions found to be reactions against globalization and European integration. 'Nationalism' does not apply to efforts to improve 'our' national and European competitiveness nor 'our' joint EU policies of external bordering.

    The uptake of dissolved organic compounds, that is, osmotrophy, has been shown to be an efficient nutritional strategy for algae. However, this mode of nutrition may affect the biochemical composition, for example, the fatty acid (FA) contents, of algal cells. This study focused on the osmotrophic assimilation of glucose and leucine by selected seven algal strains belonging to chlorophytes, chrysophytes, cryptophytes, dinoflagellates and euglenoids. Our laboratory experiments with stable isotope labeling showed that osmotrophy occurred in four of the selected seven strains. However, only three of these produced long chain omega-3 FAs eicosapentaenoic acid (EPA; 20:5 omega 3) and docosahexaenoic acid (DHA; 22:6 omega 3). High glucose content (5 mg L-1) affected negatively on the total FAs of Mallomonas kalinae and the total omega-3 FAs of Cryptomonas sp. Further, glucose assimilation explained 35% (negative effect) and leucine assimilation 48% (positive effect) of the variation of EPA, DHA and the FAs related to their synthesis in Cryptomonas sp. Moderate glucose concentration (2 mg L-1) was found to enhance the growth of Cryptomonas ozolinii, whereas low leucine (20 mu g L-1) enhanced the growth of M. kalinae. However, no systematic effect of osmotrophy on growth rates was detected. Our study shows that osmotrophic assimilation of algae is species and compound specific, and that the effects of the assimilated compounds on algal metabolism also varies depending on the species.

    Increasing importance is being attached to support students’ learning of social-emotional and self-management skills as they may experience all kinds of difficulties and problems at school. How can teachers support students to learn useful skills to overcome these problems? The purpose of this study is to assess the effectiveness of the Skillful-Class method, which teachers can use in their classrooms to support students learn social-emotional and self-management skills in a supportive and collaborative learning environment. A Skillful-Class project was conducted in 22 Finnish and 18 Chinese primary school classes. Data was collected by pre- and post-questionnaires from autumn 2018 – spring 2019. Qualitative data was collected using a post questionnaire with open-ended questions, interviews, and discussions on webpages, which were reviewed by content analysis. There is clear evidence showing that students’ skills improved significantly; further, the relationships among students, teachers, and parents also improved. The students became more supportive of and collaborative with each other. The teachers’ responses also show that their work became easier at school when students learned many social-emotional and self-management skills. Based on these findings, we can conclude that the Skillful-Class method is an effective tool for teachers to help students learn skills. Further, it improves the collaboration among teachers, students, and parents, and builds a supportive and collaborative learning community.

    This chapter is aimed to explore the role of tourism in reshaping historical cities, particularly into forms of cosmopolitan consumption. New mobility paradigms seem to merge production and consumption patterns of tourists and residents, all influenced by similar gazing and performing places. The iconic case of Venice shows patterns of staged authenticity, reconstructed ethnicity, and economy of subordination. Drivers to visit Venice include experiences in a setting that is densely characterized by cultural heritage; however, the tourist monoculture and cosmopolitan consumption have depleted the original elements of this attraction: traditional places, residents, livelihoods, material and immaterial cultures. Culture markets and international events, architectural and environmental restoration, together with private forms of transport in the fragile lagoon ecosystem, have transformed the historical city and its unique lifestyle into a place for cosmopolitan consumption, involving tourists together with new residents, sometimes integrating wealthy long-term residents in this overall tourism gentrification. Deprived of great part of what is considered to be the old and conservative block of residents, the gentrified residents acquire spaces for their cultural activities and political acts in their ‘saving Venice’ projects. Two gentrifying groups are described in this chapter: super rich with their philanthropic associations, and intellectuals. Despite clear differences in their causes and agency, both share common visions over leisurely uses of the lagoon city, artistic production and consumption of its heritage. Sustainability questions could instead propose to start from local memories to reconstruct Venice as a complex urban space with more inclusive sense of place.

    In this essay, I take up the challenge of comparative literature from a Finnish perspective and...discuss the notions of influence, intertextuality, and genres as methodological concepts of comparative literature. By exploring the relationships between French and Finnish naturalist novels, I suggest that genre study may advance the work of comparing distant literary traditions, helping us not only to cross national borders between centre and periphery, but also to bring new insights into the set of methodological problems included in the traditional study of influences and reception.

    Boreal bogs are important stores and sinks of atmospheric carbon whose surfaces are characterised by vegetation microforms. Efficient methods for monitoring their vegetation are needed because changes in vegetation composition lead to alteration in their function such as carbon gas exchange with the atmosphere. We investigated how airborne image and waveform-recording LiDAR data can be used for 3D mapping of microforms in an open bog which is a mosaic of pools, hummocks with a few stunted pines, hollows, intermediate surfaces and mud-bottom hollows. The proposed method operates on the bog surface, which is reconstructed using LiDAR. The vegetation was classified at 20 cm resolution. We hypothesised that LiDAR data describe surface topography, moisture and the presence and depth of field-layer vegetation and surface roughness; while multiple images capture the colours and texture of the vegetation, which are influenced by directional reflectance effects. We conclude that geometric LiDAR features are efficient predictors of microforms. LiDAR intensity and echo width were specific to moisture and surface roughness, respectively. Directional reflectance constituted 4-34 % of the variance in images and its form was linked to the presence of the field layer. Microform-specific directional reflectance patterns were deemed to be of marginal value in enhancing the classification, and RGB image features were inferior to LiDAR variables. Sensor fusion is an attractive option for fine-scale mapping of these habitats. We discuss the task and propose options for improving the methodology.

    This research focuses on the LEADER approach, the practice of neo-endogenous rural development inside the European Union (EU), and inside of this, one of its basic specificities, transnational cooperation projects (TNCP), specifically for Finland and Spain, and for the 2007-2013 programming period, what implementation problems have these projects faced? What effects have been derived from their application? To obtain quantitative information, the reports from the European Rural Development Network have been analyzed; and to extract detailed information, the reports of the National Rural Network of Spain, of Nordic-Baltic LEADER Cooperation Award, have been consulted, in addition to for some projects, the reports of these TNCPs of each Local Action Group; and in the cases that those responsible for these TNCPs have been found, the data extracted from a questionnaire, answered by 19 of them. The data show that PCTNs have not obtained the needed expectations, mainly due to bureaucratic, economic problems, and even, due to the lack of willingness of the initial and last stakeholders and managers in charge to implement them. Therefore, the potential for transnational cooperation remains underutilized in terms of knowledge sharing and skills development, to provide new ideas and inspiration that strengthen rural development strategies, and even to foster solidarity between different rural areas.

    We consider the simultaneous production of two heavy-flavoured hadrons – particularly D mesons – at the LHC. We base our calculations on collinearly factorized QCD at next-to-leading order, using the contemporary parton distribution functions and D-meson fragmentation functions. The contributions of double-parton scatterings are included in the approximation of independent partonic interactions. Our framework benchmarks well with the available proton-proton data from the LHCb collaboration giving us confidence to make predictions for proton-lead collisions. Our results indicate that the double D-meson production in proton-lead collisions should be measurable at the LHCb kinematics with the already collected Run-II data, and should provide evidence for double-parton scattering at perturbative scales with a nuclear target.

    Four well-studied saprotrophic Basidiomycota Agaricomycetes species with different decay strategies were cultivated on solid lignocellulose substrates to compare their extracellular decomposing carbohydrate-active and lignin-attacking enzyme production profiles. Two Polyporales species, the white rot fungus Phlebia radiata and brown rot fungus Fomitopsis pinicola, as well as one Agaricales species, the intermediate “grey” rot fungus Schizophyllum commune, were cultivated on birch wood pieces for 12 weeks, whereas the second Agaricales species, the litter-decomposing fungus Coprinopsis cinerea was cultivated on barley straw for 6 weeks under laboratory conditions. During 3 months of growth on birch wood, only the white rot fungus P. radiata produced high laccase and MnP activities. The brown rot fungus F. pinicola demonstrated notable production of xylanase activity up to 43 nkat/mL on birch wood, together with moderate β-glucosidase and endoglucanase cellulolytic activities. The intermediate rot fungus S. commune was the strongest producer of β-glucosidase with activities up to 54 nkat/mL, and a notable producer of xylanase activity, even up to 620 nkat/mL, on birch wood. Low lignin-attacking but moderate activities against cellulose and hemicellulose were observed with the litter-decomposer C. cinerea on barley straw. Overall, our results imply that plant cell wall decomposition ability of taxonomically and ecologically divergent fungi is in line with their enzymatic decay strategy, which is fundamental in understanding their physiology and potential for biotechnological applications.

    Bark of Norway spruce and Scots pine trees contain large amounts of condensed tannins. Tannins extracted with hot water could be used in different applications as they possess antioxidative and antimicrobial activities. The use of bark tannins as e.g., food preservatives calls for increases in our knowledge of their antioxidative activities when applied in foodstuffs. To assess the ability of bark tannins to prevent lipid oxidation, hot water extracts were evaluated in a liposome model. Isolated tannins were also applied in dry-cured, salty meat snacks either as liquid extracts or in dry-powder form. Consumer acceptance of the snacks was tested by a sensory evaluation panel where outlook, odor, taste, and structure of the snacks were evaluated and compared to a commercial product without tannin ingredients. Our results show that conifer bark tannin-rich extracts have high capacity to prevent lipid oxidation in the liposome model. The efficacies of pine and spruce bark extracts were ten to hundred folds higher, respectively, than those of phenolic berry extracts. The bark extracts did not significantly influence the odor or taste of the meat snacks. The findings indicate that bark extracts may be used as sustainable food ingredients. However, more research is needed to verify their safety.
