In this digital age, as social media is emerging as a central site where information is shared and interpreted, it is essential to study information construction issues on social media sites in order to understand how social reality is constructed. While there is a number of studies taking an information-as-objective point of view, this proposed study emphasizes the constructed and interpretive nature of information and explores the processes through which information surrounding acute events comes into being on micro-blogs. In order to conduct this analysis systematically and theoretically, the concept of interpretive communities will be deployed. This research investigates if or not micro-blog based social groups can serve as interpretive communities, and, if so, what role might they play in the construction of information, and the social impacts that may arise. To understand how this process is entangled with the surrounding social, political, technical contexts, cases from both China (focusing on Sina Weibo) and Australia (focusing on Twitter) will be analysed.

Cardiovascular disease is the leading causes of death in the developed world. Wall shear stress (WSS) is associated with the initiation and progression of atherogenesis. This study combined the recent advances in MR imaging and computational fluid dynamics (CFD) and evaluated the patient-specific carotid bifurcation. The patient was followed up for 3 years. The geometry changes (tortuosity, curvature, ICA/CCA area ratios, central to the cross-sectional curvature, maximum stenosis) and the CFD factors (Velocity distribute, Wall Shear Stress (WSS) and Oscillatory Shear Index (OSI)) were compared at different time points.The carotid stenosis was a slight increase in the central to the cross-sectional curvature, and it was minor and variable curvature changes for carotid centerline. The OSI distribution presents ahigh-values in the same region where carotid stenosis and normal border, indicating complex flow and recirculation.The significant geometric changes observed during the follow-up may also cause significant changes in bifurcation hemodynamics.

The primary objective of this paper is to study the use of medical image-based finite element (FE) modelling in subjectspecific midsole design and optimisation for heel pressure reduction using a midsole plug under the calcaneus area (UCA). Plugs with different relative dimensions to the size of the calcaneus of the subject have been incorporated in the heel region of the midsole. The FE foot model was validated by comparing the numerically predicted plantar pressure with biomechanical tests conducted on the same subject. For each UCA midsole plug design, the effect of material properties and plug thicknesses on the plantar pressure distribution and peak pressure level during the heel strike phase of normal walking was systematically studied. The results showed that the UCA midsole insert could effectively modify the pressure distribution, and its effect is directly associated with the ratio of the plug dimension to the size of the calcaneus bone of the subject. A medium hardness plug with a size of 95% of the calcaneus has achieved the best performance for relieving the peak pressure in comparison with the pressure level for a solid midsole without a plug, whereas a smaller plug with a size of 65% of the calcaneus insert with a very soft material showed minimum beneficial effect for the pressure relief.

Finnish scholarship students in Russia during the autonomy (1812-1917) During the autonomy in Finland (1809-1917), an attempt to improve the knowledge of the Russian language was made through special language university scholarships. With these scholarships the students could go and study the Russian language and acquire cultural knowledge in Russia. Other member countries on the edges of the Russian Empire, like Poland and the Baltic provinces, did not have similar programs. The first two scholars started their journey in 1812. A system of travel allowances was introduced in 1841. Between the years 1812- 1917 a total of almost 400 students studied in Russia. The studies mainly took place in Moscow. These scholarship students were called the Master s of Moscow ". In this paper, Finnish-Russian relations are studied based on the attitude towards the Russian language and the people who studied it in Finland. Although the attitude towards them was neutral in the beginning, in 1844 there was a strong change. Students of Russian, and especially the scholars, received the stigma of being unreliable and unpatriotic, a stigma they were never able to get rid of. The study of the Russian language was voluntary in Finnish schools between 1863 and 1872. Starting from 1890, however, the study of the Russian language was enforced. In doing so, the Russians attempted to unify the Empire, while the Finns had the illusion that they had their own state. Thus, Russia saw the language as a way to unify the Empire and Finns as an attempt to make them Russians. The purpose of studying in Russia was to improve the student s practical language skills and overall knowledge of the customs and culture of the country. Besides knowing the language, knowledge of Russian culture and customs is essential in understanding Russia and Russians; therefore, the studies of literature, geography and history have been noted in this research. Without knowledge it is difficult to develop understanding. After their studies, almost all of the scholars returned to Finland and did not continue their careers in Russia. They worked mainly as teachers and civil servants, and managed to improve the Finnish people s weak knowledge of Russian and Russia through teaching, translations of literature and newspaper articles. Through these scholars, it is possible to see how the attitudes towards the language have been closely related to the political history between Finland and Russia. The language became the subject of resistance and these attitudes were transferred to its students. In 1917, the study of Russia and the Russian language ended and it was no longer possible to use the acquired knowledge of language and country in independent Finland.

Bertrand Russell (1872 1970) introduced the English-speaking philosophical world to modern, mathematical logic and foundational study of mathematics. The present study concerns the conception of logic that underlies his early logicist philosophy of mathematics, formulated in The Principles of Mathematics (1903). In 1967, Jean van Heijenoort published a paper, Logic as Language and Logic as Calculus, in which he argued that the early development of modern logic (roughly the period 1879 1930) can be understood, when considered in the light of a distinction between two essentially different perspectives on logic. According to the view of logic as language, logic constitutes the general framework for all rational discourse, or meaningful use of language, whereas the conception of logic as calculus regards logic more as a symbolism which is subject to reinterpretation. The calculus-view paves the way for systematic metatheory, where logic itself becomes a subject of mathematical study (model-theory). Several scholars have interpreted Russell s views on logic with the help of the interpretative tool introduced by van Heijenoort,. They have commonly argued that Russell s is a clear-cut case of the view of logic as language. In the present study a detailed reconstruction of the view and its implications is provided, and it is argued that the interpretation is seriously misleading as to what he really thought about logic. I argue that Russell s conception is best understood by setting it in its proper philosophical context. This is constituted by Immanuel Kant s theory of mathematics. Kant had argued that purely conceptual thought basically, the logical forms recognised in Aristotelian logic cannot capture the content of mathematical judgments and reasonings. Mathematical cognition is not grounded in logic but in space and time as the pure forms of intuition. As against this view, Russell argued that once logic is developed into a proper tool which can be applied to mathematical theories, Kant s views turn out to be completely wrong. In the present work the view is defended that Russell s logicist philosophy of mathematics, or the view that mathematics is really only logic, is based on what I term the Bolzanian account of logic . According to this conception, (i) the distinction between form and content is not explanatory in logic; (ii) the propositions of logic have genuine content; (iii) this content is conferred upon them by special entities, logical constants . The Bolzanian account, it is argued, is both historically important and throws genuine light on Russell s conception of logic.

This thesis examines the ruins of the medieval Bridgettine (Birgittan) monastery of Naantali (Vallis Gratiae, f. 1443) in Finland and the transformation of the site into a national heritage and a memory landscape. It was archaeologically surveyed in the 19th century by Professor Sven Gabriel Elmgren (1817 1897). His work was followed by Dr. Reinhold Hausen (1850 1942), who excavated the site in the 1870s. During this time the memories of Saint Bridget (Birgitta) in Sweden were also invented as heritage. Hausen published his results in 1922 thus forming the connection with the next generation of actors involved with the Naantali site: the magnate Amos Anderson (1878 1961), the teacher Julius Finnberg (1877 1955) and the archaeologist Juhani Rinne (1872 1950). They erected commemorative monuments etc. on the Naantali site, thus creating a memory landscape there. For them, the site represented the good homeland in connection with a western-oriented view of the history of Finland. The network of actors was connected to the Swedish researchers and so-called Birgitta Friends, such as state antiquarian Sigurd Curman (1879 1966), but also to the members of the Societas Sanctae Birgittae and the Society for the Embellishment of Pirita, among others. Historical jubilees as manifestations of the use of history were also arranged in Naantali in 1943, 1993 and 2003. It seems as if Naantali is needed in Finnish history from time to time after a period of crisis, i.e. after the Crimean War in the 1850s, the civil war of 1918, during World War II and also after the economic crisis of the early 1990s. In 2003, there was a stronger focus on the international Saint Bridget Jubilee in Sweden and all over Europe. Methodologically, the thesis belongs to the history of ideas, but also to research on the use of history, invented traditions and lieux de mémoire. The material for the work consists of public articles and scholarly texts in books or newspapers and letters produced by the actors and kept in archives in Finland, Sweden and Estonia, in addition to pictures and erected commemorative monuments in situ in the Western Finnish region.

I avhandlingen analyseras den finlandssvenska författaren Mikael Lybecks (1864-1925) verk Breven till Cecilia. Denna brevroman hör till Lybecks senare produktion och utkom 1920. Verket har kommit att betraktas som en klassiker inom den finlandssvenska litteraturen. Av författarensövriga produktion är det strängt taget endast Tomas Indal (1911) som haft en jämförbar genomslagskraft. Trots detta har romanen inte varit föremål för en enda mer omfattande studie. l sin Lybeckbiografi relaterar Erik Kihlman i första hand verket till det biografiska och till samhällssituationen vid tiden för romanens tillkomst. Vetenskapen, konsten och livet bildar tillsammans den triangel som utgör romanens stomme. Antiken är starkt närvarande i romanen och med begrepp som härrör från denna era kan man tala om det sokratiska, det apollinska och det dionysiska. Detta är begrepp som Friedrich Nietzsche utgår i från i sitt ungdomsverk Tragedins födelse (Die Geburt der Tragödie aus dem Geiste der Musik) från 1872. Nietzsches vetenskapskritik och hans syn på den högsta konsten som ett brödraförbund mellan Dionysos och Apollon står i förvånansvärt hög grad i samklang med den övergripande tematiken i Lybecks verk. När Nietzsche därtill framhäver musiken som grunden förall konst får många inslag i romanen sin förklaring. l Breven till Cecilia skildras en vändpunkt i huvudpersonen Sven Ingelets liv. Därför ligger tyngdpunkten i den tematiska analysen vid det som gör att verket kan betraktas som en utvecklingsroman. Även om romanen skildrar en tidsperiod på endast ett och ett halvt år så hinnerhuvudpersonen ändå undergå en betydande personlighetsförändring. Nietzsches Tragedinsfödelse med dess ovannämnda grundläggande begrepp lämpar sig ypperligt som referensram för en analys av denna förändring. Avhandlingen har också strukturerats utgående från de nietzscheanska begreppen sokratiskt, dionysiskt och apollinskt vilka alltså återspeglar huvudpersonens utvecklingsfaser. Från att ha varit en renodlad förnuftsmänniska väcks Sven Ingelet genom ett kortvarigt kärleksförhållande till det dionysiska med allt vad det innebär av känslorus och lidande. Att Ingelet nästan helt uppgått i sin roll som konstteoretiker har medfört att hans förhållningssätt till omvärlden utmärks av intresselös betraktelse. Till följd av sin viljesvaghet och bristande handlingskraft måstehan försöka behålla sin älskades gunst genom magiska pseudohandlingar. Detta leder in Ingelet i myternas värld. Hans verklighetsuppfattning får andra dimensioner än den vetenskapliga. Det dionysiska uppvaknandet medför tillsammans med det efterföljande brevskrivandet att Ingeletnår fram till en självkännedom och upphör att vara en främling i tillvaron. Ingelet utvecklar ocksåen ny konstsyn som förutsätter ett samband mellan konsten och livet. Detta apollinska utvecklingsstadium kännetecknas också av sanningsförmedlande drömmar, och av en tilltagande resignation som till slut utmynnar i ett självmord. Nyckelord: brevroman, Dionysos, Apollon, främlingskap, verklighetsflykt

What is calf wastage. Breeding female cattle in north Australia contribute best to business success by producing a heavy weaner each year at the first weaning round. This maximises increase in value by the cow unit over the year, generally from mid-year to mid-year. The ability to cycle in both maiden heifers and lactating cows is the primary limitation to achieving this. Wastage of a calf at any stage between conception and weaning also substantially limits fertility and value increase at a herd level. Embryo loss may result in later calves as cows re-conceive; the calves produced are smaller at weaning and have to be weaned later into the dry season. Late calf wastage usually results in breeders missing a calf for the year. Late calving often also results in failure to cycle, thus cows rear a calf in the subsequent year.

A 2000-03 study to improve irrigation efficiency of grassed urban public areas in northern Australia found it would be difficult to grow most species in dry areas without supplementary watering. Sporoboulus virginicus and sand couch, Zoysia macrantha, were relatively drought-tolerant. Managers of sporting fields, parks and gardens could more than halve their current water use by irrigating over a long cycle, irrigating according to seasonal conditions and using grasses with low water use and sound soil management practices that encourage deep rooting. The use of effluent water provides irrigation and fertiliser cost savings and reduced nitrogen and phosphorus discharge to local waterways. Projected savings are $8000/ha/year in water costs for a typical sporting field.
