Filosofins renässans eller modern mystik : Bergsondebatten i Finland

The study examines the debate in Finland at the beginning of the 20th century surrounding the philosophy of Henri Bergson. Both within as well as outside of academic philosophy Bergsonism was adapted to the philosophical and cultural landscape in Finland by a process of selective appropriation. The ambiguous relationship between the sender and the receiver is accentuated in reference to philosophical celebrities such as Bergson, whose reputations spread more quickly than the content of their philosophy and whose names are drawn into the political and social discourse. As a philosophical movement the aim of Bergsonism was to create a scientific philosophy of life as an alternative to both idealism and modern empirical and antimetaphysical currents, during a period when European philosophy was searching for new guidelines after the collapse of the idealistic system philosophies of the 19th century. This reorientation is examined from a Finnish viewpoint and in the light of the process of intellectual importation. The study examines how elements from an international discourse were appropriated within the philosophical field in Finland against a background of changes in the role of the university and the educated elites as well as the position of philosophy within the disciplinary hierarchy. Philosophical reception was guided by expectations that had arisen in a national context, for example when Bergsonism in Finland was adjusted to a moral and educational ideal of self-cultivation, and often served as a means for philosophers to internationalize their own views in order to strengthen their position on the national stage. The study begins with some introductory remarks on the international circulation of ideas from the point of view of the periphery. The second section presents an overview of the shaping of the philosophical field at the turn of the 20th century, the naturalism and positivism of the late 19th century that were the objects of Bergson s critique, and an introduction to the attempts of a philosophy of life to make its way between idealism and naturalism. The third and main section of the study begins with a brief presentation of the main features of the philosophy of Bergson, followed by a closer examination of the different comments and analyses that it gave rise to in Finland. The final section addresses the ideological implications of Bergsonism within the framework of a political annexation of the philosophy of life at the beginning of the 20th century.

Intensity, productivity and efficiency in agriculture in Finland and implications for N and P fertiliser management

The purpose of this study was to evaluate intensity, productivity and efficiency in agriculture in Finland and show implications for N and P fertiliser management. Environmental concerns relating to agricultural production have been and still are focused on arguments about policies that affect agriculture. These policies constrain production while demand for agricultural products such as food, fibre and energy continuously increase. Therefore the importance of increasing productivity is a great challenge to agriculture. Over the last decades producers have experienced several large changes in the production environment such as the policy reform when Finland joined the EU 1995. Other and market changes occurred with the further EU enlargement with neighbouring countries in 2005 and with the decoupling of supports over the 2006-2007 period. Decreasing prices a decreased number of farmers and decreased profitability in agricultural production have resulted from these changes and constraints and of technological development. It is known that the accession to the EU 1995 would herald changes in agriculture. Especially of interest was how the sudden changes in prices of commodities on especially those of cereals, decreased by 60%, would influence agricultural production. The knowledge of properties of the production function increased in importance as a consequence of price changes. A research on the economic instruments to regulate productions was carried out and combined with earlier studies in paper V. In paper I the objective was to compare two different technologies, the conventional farming and the organic farming, determine differences in productivity and technical efficiency. In addition input specific or environmental efficiencies were analysed. The heterogeneity of agricultural soils and its implications were analysed in article II. In study III the determinants of technical inefficiency were analysed. The aspects and possible effects of the instability in policies due to a partial decoupling of production factors and products were studied in paper IV. Consequently connection between technical efficiency based on the turnover and the sales return was analysed in this study. Simple economic instruments such as fertiliser taxes have a direct effect on fertiliser consumption and indirectly increase the value of organic fertilisers. However, fertiliser taxes, do not fully address the N and P management problems adequately and are therefore not suitable for nutrient management improvements in general. Productivity of organic farms is lower on average than conventional farms and the difference increases when looking at selling returns only. The organic sector needs more research and development on productivity. Livestock density in organic farming increases productivity, however, there is an upper limit to livestock densities on organic farms and therefore nutrient on organic farms are also limited. Soil factors affects phosphorous and nitrogen efficiency. Soils like sand and silt have lower input specific overall efficiency for nutrients N and P. Special attention is needed for the management on these soils. Clay soils and soils with moderate clay content have higher efficiency. Soil heterogeneity is cause for an unavoidable inefficiency in agriculture.

How Can Sustainable Agricultural Systems Promote Food Security in a Changing Climate?

A theoretical framework of the link between climate change, rural development, sustainable agriculture, poverty, and food security is presented. Some options to respond to climate change are described. Current knowledge and potential effects on agricultural productivity is discussed. Necessary conditions for successful adaptation includes secured property rights to land, institutions that make market access possible and credit possibilities. The options of mitigation and enhanced adaptive capacity and the requirements for their implementation are discussed.

Word order and tonal shape in the production of focus in short Finnish utterances

This paper presents results from a study on the production of Finnish prosody. The effect of word order and the tonal shape in the production of Finnish prosody was studied as produced by 8 native Finnish speakers. Predictions formulated with regard to results from an earlier study pertaining to the perception of promi- nence were tested. These predictions had to do with the tonal shape of the utterances in the form of a flat hat pattern and the effect of word order on the so called top-line declination within an adver- bial phrase in the utterances. The results from the experiment give support to the following claims: the temporal domain of prosodic focus is the whole utterance, word order reversal from unmarked to marked has an effect on the production of prosody, and the pro- duction of the tonal aspects of focus in Finnish follows a basic flat hat pattern. That is the prominence of a word can be produced by an f 0 rise or a fall, depending on the location of the word in an utterance. The basic accentual shape of a Finnish word is then not a pointed rise/fall hat shape as claimed before since it can vary depending on the syllable structure and the position within an ut- terance.

Magnetically induced currents and magnetic response properties of molecules

The magnetically induced currents in organic monoring and multiring molecules, in Möbius shaped molecules and in inorganic all-metal molecules have been investigated by means of the Gauge-including magnetically induced currents (GIMIC) method. With the GIMIC method, the ring-current strengths and the ring-current density distributions can be calculated. For open-shell molecules, also the spin current can be obtained. The ring-current pathways and ring-current strengths can be used to understand the magnetic resonance properties of the molecules, to indirectly identify the effect of non-bonded interactions on NMR chemical shifts, to design new molecules with tailored properties and to discuss molecular aromaticity. In the thesis, the magnetic criterion for aromaticity has been adopted. According to this, a molecule which has a net diatropic ring current might be aromatic. Similarly, a molecule which has a net paratropic current might be antiaromatic. If the net current is zero, the molecule is nonaromatic. The electronic structure of the investigated molecules has been resolved by quantum chemical methods. The magnetically induced currents have been calculated with the GIMIC method at the density-functional theory (DFT) level, as well as at the self-consistent field Hartree-Fock (SCF-HF), at the Møller-Plesset perturbation theory of the second order (MP2) and at the coupled-cluster singles and doubles (CCSD) levels of theory. For closed-shell molecules, accurate ring-current strengths can be obtained with a reasonable computational cost at the DFT level and with rather small basis sets. For open-shell molecules, it is shown that correlated methods such as MP2 and CCSD might be needed to obtain reliable charge and spin currents. The basis set convergence has to be checked for open-shell molecules by performing calculations with large enough basis sets. The results discussed in the thesis have been published in eight papers. In addition, some previously unpublished results on the ring currents in the endohedral fullerene Sc3C2@C80 and in coronene are presented. It is shown that dynamical effects should be taken into account when modelling magnetic resonance parameters of endohedral metallofullerenes such as Sc3C2@C80. The ring-current strengths in a series of nano-sized hydrocarbon rings are related to static polarizabilities and to H-1 nuclear magnetic resonance (NMR) shieldings. In a case study on the possible aromaticity of a Möbius-shaped [16]annulene we found that, according to the magnetic criterion, the molecule is nonaromatic. The applicability of the GIMIC method to assign the aromatic character of molecules was confirmed in a study on the ring currents in simple monocylic aromatic, homoaromatic, antiaromatic, and nonaromatic hydrocarbons. Case studies on nanorings, hexaphyrins and [n]cycloparaphenylenes show that explicit calculations are needed to unravel the ring-current delocalization pathways in complex multiring molecules. The open-shell implementation of GIMIC was applied in studies on the charge currents and the spin currents in single-ring and bi-ring molecules with open shells. The aromaticity predictions that are made based on the GIMIC results are compared to other aromaticity criteria such as H-1 NMR shieldings and shifts, electric polarizabilities, bond-length alternation, as well as to predictions provided by the traditional Hückel (4n+2) rule and its more recent extensions that account for Möbius twisted molecules and for molecules with open shells.

EFFEKTUTVÄRDERING INOM FÖRETAGANDEUTBILDNING

Effektutvärdering inom företagandeutbildning är ett forskningsfält som karakteriseras av brist på modeller ifråga om utvärdering. De få och hittills existerande utvärderingsmodellerna verkar ha förbisett de pedagogiska variablerna såsom utbildningens innehåll och metoder. Därför har det varit problematiskt att beskriva företagandeutbildningen i högskolor och analysera hur företagandeutbildningen bidrar till studerandes inlärning och deras förmåga att utnyttja kunskapen i näringslivet. Avhandlingen som är en deduktiv studie granskar den tidigare forskningen på området och förespråkar en tvärvetenskaplig ansats vid mätning och presentation aveffekter inom företagandeutbildning. Den nya modellen, ROEE-modellen, bidrar till teoribildningen om lärandets ”vad” och lärandets ”hur” inom företagandeutbildningen. En av de första teorierna om inlärning (Herbart 1776-1841) och Kirkpatricks (1998) fyra-stegs modell för kursutvärdering byggs ut med en ny referensram baserad på examensutbildning inom företagande. En intressant aspekt metodmässigt utgör att försöksplanering och diagnostik inom medicinens område tillämpas på företagandeutbildningen. Avhandlingen visar att variabeln innehåll i företagandeutbildningen inom examensutbildning har en klar koppling till beteendet. Ett välavvägt innehåll kan utnyttjas i arbetslivet såväl av entreprenören som av intraprenören. Vid metodval i undervisningen visar den empiriska undersökningen att variation i metoder ger de positivaste upplevelserna.
