As we enter the second phase of creative industries there is a shift away from the early 1990s ideology of the arts as a creative content provider for the wealth generating ‘knowledge’ economy to an expanded rhetoric encompassing ‘cultural capital’ and its symbolic value. A renewed focus on culture is examined through a regional scan of creative industries in which social engineering of the arts occurs through policy imperatives driven by ‘profit oriented conceptualisations of culture’ (Hornidge 2011, p. 263) In the push for artists to become ‘culturpreneurs’ a trend has emerged where demand for ‘embedded creatives’ (Cunningham 2013) sees an exodus from arts-based employment through use of transferable skills into areas outside the arts. For those that stay, within the performing arts in particular, employment remains project-based, sporadic, underpaid, self-initiated and often self-financed, requiring adaptive career paths. Artist entrepreneurs must balance creation and performance of their art with increasing amounts of time spent on branding, compliance, fundraising and the logistical and commercial requirements of operating in a CI paradigm. The artists’ key challenge thus becomes one of aligning core creative and aesthetic values with market and business considerations. There is also the perceived threat posed by the ‘prosumer’ phenomenon (Bruns 2008), in which digital on-line products are created and produced by those formerly seen as consumers of art or audiences for art. Despite negative aspects to this scenario, a recent study (Steiner & Schneider 2013) reveals that artists are happier and more satisfied than other workers within and outside the creative industries. A lively hybridisation of creative practice is occurring through mobile and interactive technologies with dynamic connections to social media. Continued growth in arts festivals attracts participation in international and transdisciplinary collaborations, whilst cross-sectoral partnerships provide artists with opportunities beyond a socio-cultural setting into business, health, science and education. This is occurring alongside a renewed engagement with place through the rise of cultural precincts in ‘creative cities’ (Florida 2008, Landry 2000), providing revitalised spaces for artists to gather and work. Finally, a reconsideration of the specialist attributes and transferable skills that artists bring to the creative industries suggests ways to dance through both the challenges and opportunities occasioned by the current complexities of arts’ practices.

Stress- and strain-controlled tests of heat treated high-strength rail steel (Australian Standard AS1085.1) have been performed in order to improve the characterisation of the said material׳s ratcheting and fatigue wear behaviour. The hardness of the rail head material has also been studied and it has been found that hardness reduces considerably below four-millimetres from the rail top surface. Historically, researchers have used test coupons with circular cross-sections to conduct cyclic load tests. Such test coupons, typically five-millimetres in gauge diameter and ten‐millimetres in grip diameter, are usually taken from the rail head sample. When there is considerable variation of material properties over the cross-section it becomes likely that localised properties of the rail material will be missed. In another case from the literature, disks 47 mm in diameter for a twin-disk rolling contact test machine were obtained directly from the rail sample and used to validate ratcheting and rolling contact fatigue wear models. The question arises: How accurate are such tests, especially when large material property gradients exist? In this research paper, the effects of rail sampling location on the ratcheting behaviour of AS1085.1 rail steel were investigated using rectangular-shaped specimens obtained at four different depths to observe their respective cyclic plasticity behaviour. The microstructural features of the test coupons were also analysed, especially the pearlite inter-lamellar spacing which showed strong correlation with both hardness and cyclic plasticity behaviour of the material. This work ultimately provides new data and testing methodology to aid the selection of valid parameters for material constitutive models to better understand rail surface ratcheting and wear.

In the post-World War II era human rights have emerged as an enormous global phenomenon. In Finland human rights have particularly in the 1990s moved from the periphery to the center of public policy making and political rhetoric. Human rights education is commonly viewed as the decisive vehicle for emancipating individuals of oppressive societal structures and rendering them conscious of the equal value of others; both core ideals of the abstract discourse. Yet little empirical research has been conducted on how these goals are realized in practice. These factors provide the background for the present study which, by combining anthropological insights with critical legal theory, has analyzed the educational activities of a Scandinavian and Nordic network of human rights experts and PhD students in 2002-2005. This material has been complemented by data from the proceedings of UN human rights treaty bodies, hearings organized by the Finnish Foreign Ministry, the analysis of different human rights documents as well as the manner human rights are talked of in the Finnish media. As the human rights phenomenon has expanded, human rights experts have acquired widespread societal influence. The content of human rights remains, nevertheless, ambiguous: on the one hand they are law, on the other, part of a moral discourse. By educating laymen on what human rights are, experts act both as intermediaries and activists who expand the scope of rights and simultaneously exert increasing political influence. In the educational activities of the analyzed network these roles were visible in the rhetorics of legality and legitimacy . Among experts both of these rhetorics are subject to ongoing professional controversy, yet in the network they are presented as undisputable facts. This contributes to the impression that human rights knowledge is uncontested. This study demonstrates how the network s activities embody and strengthen a conception of expertise as located in specific, structurally determined individuals. Simultaneously its conception of learning emphasizes the adoption of knowledge by students, emphasizing the power of experts over them. The majority of the network s experts are Nordic males, whereas its students are predominantly Nordic females and males from East-European and developing countries. Contrary to the ideals of the discourse the network s activities do not create dialogue, but instead repeat power structures which are themselves problematic.

"Body and Iron: Essays on the Socialness of Objects" focuses on the bodily-material interaction of human subjects and technical objects. It poses a question, how is it possible that objects have an impact on their human users and examines the preconditions of active efficacy of objects. In this theoretical task the work relies on various discussions drawing from realistic ontology, phenomenology of body, neurophysiology of Antonio Damasio and psychoanalysis to establish both objects and bodies as material entities related in a causal interaction with each other. Out of material interaction emerge a symbolic field, psyche and culture that produce representations of interactions with material world they remain dependent on and conditioned by. Interaction with objects informs the human body via its somatosensory systems: interoseptive and proprioseptive (or kinesthetic) systems provide information to central nervous system of the internal state of the body and muscle tensions and motor activity of the limbs. Capability to control the movements of one's body by the internal "feel" of being a body turns out to be a precondition to the ability to control artificial extensions of the body. Motor activity of the body is involved in every perception of environment as the feel of one's own body is constitutive of any perception of external objects. Perception of an object cause changes in the internal milieu of the body and these changes in the organism form a bodily representation of an external object. Via these "muscle images" the subject can develop a feel for an instrument. Bodily feel for an object is pre-conceptual, practical knowledge that resists articulation but allows sensing the world through the object. This is what I would call sensual knowledge. Technical objects intervene between body and environment, transforming the relation of perception and motor activity. Once connected to a vehicle, human subject has to calibrate visual information of his or her position and movement in space to the bodily actions controlling the machine. It is the machine that mediates the relation of human actions to the relation of her body to its environment. Learning to use the machine necessarily means adjusting his or her bodily actions to the responses of the machine in relation to environmental changes it causes. Responsiveness of the machine to human touch "teaches" its subject by providing feedback of the "correctitude" of his or her bodily actions. Correct actions form a body technique of handling the object. This is the way of socialness of objects. While responding to human actions they generate their subjects. Learning to handle a machine means accepting the position of the user in the program of action materialized in the construction of the object. Objects mediate, channel and transform the relation of the body to its environment and via environment to the body itself according to their material and technical construction. Objects are sensory media: they channel signals and information from the environment thus constituting a representation of environment, a virtual or artificial reality. They also feed the body directly with their powers equipping their user with means of regulating somatic and psychic states of her self. For these reasons humans look for the company of objects. Keywords: material objects, material culture, sociology of technology, sociology of body, mobility, driving

The study examines the term "low threshold" from the point of view of the most marginalized drug users. While using illicit drugs is criminalised and morally judged in Finland, users have special barriers to seek for care. Low threshold services aim at reaching drug users who themselves don t seek for help. "Low threshold" is a metaphor describing easy access to services. The theoretical frame of reference of the study consists of processing the term analytically and critically. The research work sets out to test the rhetoric of low threshold by making use of a qualitative multi-case study to find out, if the threshold of so called low threshold services always appears low for the most marginalized drug users. The cases are: the mobile unite offering health counselling, the day service centre for marginalized substance abusers and the low threshold project of the outpatient clinic for drug users in Helsinki and the health counselling service trial in Vyborg, Russia. The case study answer following questions: 1) How do the method of low threshold work out in the studied cases from the point of view of the most marginalized drug users? 2) How do potential thresholds appear and how did they develop? 3) How do the most marginalized drug users get into the care system through low threshold? The data consists of interviews of drug users, workers and other specialists having been accomplished in the years 2001 - 2006, patient documents and customer registers. The dissertation includes four articles published in the years 2006 - 2008 and the summary article. The study manifests that even low threshold is not always low enough for the most marginalized drug users. That expresses a highly multiproblematised and underpriviledged group of drug users, whose life and utilization of services are framed by deep marginalisation, homelessness, multi-substance use, mental and somatic illnesses and being repeatedly imprisoned. Using services is rendered difficult by many factors arising from the care system, drug users themselves and the action environment. In Finland thresholds are generally due to the execution of practical services and procedures not considering the fear of control and labelling as a drug user. When striving for further rehabilitating substance abuse care by means of low threshold services the marginalized drug users meet the biggest difficulties. They are due to inelastic structures, procedures and division of labour in the established care system and also to poor chances of drug users to be in action in the way expected by the care system. Multiproblematic multisubstance users become "wrong" customers by high expectations of care motivation and specializing in the care system. In Russia the thresholds are primarily caused by rigid control politics directed to drug users by the society and by the scantiness of care system. The ideology of reducing drug related harm is not approved and the care system is unwilling to commit to it. Low threshold turnes out to be relative as a term. The rhetoric of the care system is not enough to unilaterally define lowness of the threshold. The experiences of drug users and the actual activity to search for care determine the threshold. It does not appear the same for everybody either. Access of certain customer group to a service unit may even raise the threshold for some other group. The low threshold system also is surprisingly realized: you could not always tell in advance, what kind of customers and how many of them could be reached. Keywords: low threshold, marginalized drug users, harm reduction, barriers to services, outreach

Tutkimuksen keskeinen tehtävä on selvittää, mikä on dokumentoinnin merkitys lastensuojelun sosiaalityön tiedonmuodostuksessa ja ammattikäytännöissä. Asiakirjateksteistä koostuvaa tutkimusaineistoa tarkastellaan kolmesta eri suunnasta kysymällä: 1)Miten asiakirjoja kirjoitetaan? 2) Mitä asiakirjoihin kirjoitetaan? 3) Miksi asiakirjoja kirjoitetaan niin kuin kirjoitetaan? Tutkimusaineisto muodostuu lastensuojelun sosiaalityöntekijöiden laatimista asiakastietojärjestelmään tallennetuista muistiinpanoista ja huostaanottopäätöksistä. Tutkimukseen on valittu 20 huostaanotetun eri-ikäisen lapsen ja heidän perheensä asiakirjat yhteensä 1613 asiakirjatulostussivua. Tekstit ajoittuvat vuodesta 1989 vuoteen 2000. Tutkimusmenetelmä on diskurssianalyyttinen ja tukeutuu Fairclough`n (1997)esittämään kolmiulotteiseen malliin, jossa diskurssi määritellään tekstin, käytäntöjen ja sosiokulttuurisen ympäristön suhteeksi. Diskurssianalyysi on näiden rakenteiden ja niiden välisten suhteiden kuvaamista, tulkintaa ja selittämistä. Fairclough’n mallia mukaillen tutkimuksen analyysi koostuu retoriikan ja tematiikan analyyseistä sekä pragmatiikan näkökulman sisältävästä tarkastelusta. Asiakirjatekstien pilkkominen puhujakategorioihin osoitti tekstien olevan moniäänisiä, useiden henkilöiden näkemyksiä ja mielipiteitä sisältäviä tekstipintoja. Retoriikan analyysi näytti, että lastensuojelun sosiaalityön asiakirjat sisältävät paljon dynaamisia kuvauksia työstä. Asiakirjojen kirjoittaminen moniäänisiksi tuo tekstiin uskottavuutta, ja se on myös yksi retorinen vaikuttamiskeino. Tematiikan tarkastelu osoitti,että asiakirjojen sisällölliset teemat (lapsen hoiva, arjen hallinta, yhteistyö ja päihteiden käyttö) ja kokemukselliset teemat (huoli, vastuu, yhteys ja moraali) toistuvat sisäkkäisinä ja päällekkäisinä säikeinä dynaamisesti vaihdellen. Sosiaalityöntekijät kirjaavat teksteihin monia yhtäaikaisia teemoja, joiden avulla rakentavat ammatillista ymmärrystä kyseessä olevasta tilanteesta. Asiakirjojen tutkiminen pragmatiikan suunnasta toi esiin, kirjoittamisen ja lukemisen kontekstiulottuvuudet sekä tiedonmuodostusprosessin. Asiakirjojen laatiminen on osa sosiaalityön käytäntöjä. Se on myös keskeinen alue ammattikunnan yhteisen ammatillisen ymmärryksen luomisessa ja ylläpitämisessä. Muistiinpanot, huostaanottopäätökset ja lakitekstit ovat intertekstuaalisia. Lastensuojelun sosiaalityön asiakirjojen tutkiminen on avannut uusia mahdollisuuksia ymmärtää sosiaalityön dokumentointiprosessia, merkitystä ja roolia sekä tiedonmuodostuksen dynamiikkaa. Tekstien kirjoittaminen, niiden lukeminen, tietojen siirtäminen ja asiakkaan kuuleminen samoin kuin kuulemisen kirjaaminen ovat sosiaalityön dokumentoinnin keskeisiä haasteita. Tutkimus pyrkii avaamaan ymmärrystä asiakirjatekstien monivivahteiseen ja dynaamiseen maailmaan ja siten myös sosiaalityön dokumentoinnin arkeen. Tarkastelut mahdollistavat työn kehittämisen erityisesti sosiaalityön asiakasvaikuttavuuden mittaamisen ja parantamisen suuntaan. Asiakirjoissa ilmenevä tiedonmuodostuksen dynamiikka syntyy kirjoittamiskäytäntöjen, kirjoittamisen ja lukemisen sekä toimintakäytäntöjen yhteisessä alueessa. Avainsanat: sosiaalityö, lastensuojelu, dokumentointi, asiakirja, diskurssianalyysi, tiedonmuodostus.

Since the 1990s, European policy strategies have stressed the mutual responsibility and joint action of all societal branches in preventing social problems. Network policy is an integral part of the new governance that generates a new kind of dependency between the state and civil society in formulating and adhering to policy goals. Using empirical group interview data collected in Helsinki, the capital of Finland, this case study explores local multi-agency groups and their efforts to prevent the exclusion of children and young people. These groups consist mainly of professionals from the social office, youth clubs and schools. The study shows that these multi-agency groups serve as forums for professional negotiation where the intervention dilemma of liberal society can be addressed: the question of when it is justified and necessary for an authority or network to intervene in the life of children and their families, and how this is to be done. An element of tension in multi-agency prevention is introduced by the fact that its objectives and means are anchored both in the old tradition of the welfare state and in communitarian rhetoric. Thus multi-agency groups mend deficiencies in wellbeing and normalcy while at the same time try to co-ordinate the creation of the new community, which will hopefully reduce the burden on the public sector. Some of the professionals interviewed were keen to see new and even forceful interventions to guide the youth or to compel parents to assume their responsibilities. In group discussions, this approach often met resistance. The deeper the social problems that the professionals worked with, the more solidarity they showed for the families or the young people in need. Nothing seems to assure professionals and to legitimise their professional position better than advocating the under-privileged against the uncertainties of life and the structural inequalities of society. The groups that grappled with the clear, specific needs of certain children and families were the most capable of co-operation. This requires the approval of different powers and the expertise of distinct professions as well as a forum to negotiate case-specific actions in professional confidentiality. The ideals of primary prevention for everyone and value discussions alone fail to inspire sufficient multiagency co-operation. The ideal of a network seems to give word and shape to those societal goals that are difficult or even impossible to reach, but are nevertheless yearned for: mutual understanding of the good life, close social relationships, mutual trust and active agency for all citizens. Individualisation, the multiplicity of life styles and the possibility to choose have come true in such a way that the very idea of a mutual and binding network can be attained only momentarily and between restricted participants. In conclusion, uniting professional networks that negotiate intervention dilemmas with citizen networks based on changing compassions and feelings of moral superiority seems impossible. Rather, one should encourage openness to scrutiny among tangential or contradicting groups, networks and communities. Key words: network policy, prevention of exclusion, multi-agency groups, young people

The present paper investigates the nature of the fluid flow when a spheroid is suspended in an infinitely extending elastico-viscous fluid defined by the constitutive equations given by Oldroyd or Rivlin and Ericksen, and is made to perform small amplitude oscillations along its axis. The solution of the vector wave equation is expressed in terms of the solution of the corresponding scalar wave equation, without the use of Heine's function or spheroidal wave functions. Two special cases (i) a sphere and (ii) a spheroid of small ellipticity, are studied in detail.

The doctoral dissertation Critic Einari J. Vehmas and Modern Art deals with one of the central figures of the Finnish art scene and his work as an art critic, art museum curator and cultural critic. The main body of research material consists of the writings of Einari J. Vehmas (1902 1980) from 1937 to the late 1960s. Vehmas wrote art reviews for magazines, and from the year 1945 he was a regular art critic for one of the major newspapers in Finland. Vehmas was heavily inclined towards French literature and visual arts. Marcel Proust and Charles Baudelaire influenced his views on the nature of art from the late 1920s onwards. Vehmas is commonly regarded as the most influential art critic of post-war Finland. His writings have been referred to and cited in numerous research papers on Finnish 20th-century art. A lesser known aspect of his work is his position as the deputy director of the Ateneum Art Museum, the Finnish national gallery. Through his art museum work, his opinions also shaped the canon of modern art considered particularly Finnish following the second world war. The main emphasis of the dissertation is on studying Vehmas s writings, but it also illustrates the diversity of his involvement in Finnish cultural life through biographical documents. The long chronological span of the dissertation emphasises how certain central themes accumulate in Vehmas s writings. The aim of the dissertation is also to show how strongly certain philosophical and theoretical concepts from the early 20th century, specifically Wassily Kandinsky s principle of inner necessity and Henri Bergson s epistemology highlighting intuition and instinct, continued to influence the Finnish art discourse even in the early 1960s, in part thanks to the writings of Vehmas. Throughout his production, Vehmas contemplated the state and future of modern art and humanity. Vehmas used a colourful, vitalistic rhetoric to emphasise the role of modern art as a building block of culture and humanity. At the same time, however, he was a cultural pessimist whose art views became infused with anxiety, a sense of loss, and a desire to turn his back on the world.

The Ramberg-Osgood relation which adequately describes the stress-strain curve of a strain-hardening material is extended to formulate the constitutive laws for creep. The constitutive laws which describe primary creep adequately are extended to secondary creep. The results are verified for the case of R.R. 59 at 200°C, Nimonic 80A and Nimonic 90 alloys at 750°C.

The flow generated by the rotation of a sphere in an infinitely extending fluid has recently been studied by Goldshtik. The corresponding problem for non-Newtonian Reiner-Rivlin fluids has been studied by Datta. Bhatnagar and Rajeswari have studied the secondary flow between two concentric spheres rotating about an axis in the non-Newtonian fluids. This last investigation was further generalised by Rajeswari to include the effects of small radial suction or injection. In Part A of the present investigation, we have studied the secondary flow generated by the slow rotation of a single sphere in non-Newtonian fluid obeying the Rivlin-Ericksen constitutive equation. In Part B, the effects of small suction or injection have been studied which is applied in an arbitrary direction at the surface of the sphere. In the absence of suction or injection, the secondary flow for small values of the visco-elastic parameter is similar to that of Newtonian fluids with inclusion of inertia terms in the Oseen approximation. If this parameter exceeds Kc = 18R/219, whereR is the Reynolds number, the breaking of the flow field takes place into two domains, in one of which the stream lines form closed loops. For still higher values of this parameter, the complete reversal of the sense of the flow takes place. When suction or injection is included, the breaking of the flow persists under certain condition investigated in this paper. When this condition is broken, the breaking of the flow is obliterated.

Masonry strength is dependent upon characteristics of the masonry unit,the mortar and the bond between them. Empirical formulae as well as analytical and finite element (FE) models have been developed to predict structural behaviour of masonry. This paper is focused on developing a three dimensional non-linear FE model based on micro-modelling approach to predict masonry prism compressive strength and crack pattern. The proposed FE model uses multi-linear stress-strain relationships to model the non-linear behaviour of solid masonry unit and the mortar. Willam-Warnke's five parameter failure theory developed for modelling the tri-axial behaviour of concrete has been adopted to model the failure of masonry materials. The post failure regime has been modelled by applying orthotropic constitutive equations based on the smeared crack approach. Compressive strength of the masonry prism predicted by the proposed FE model has been compared with experimental values as well as the values predicted by other failure theories and Eurocode formula. The crack pattern predicted by the FE model shows vertical splitting cracks in the prism. The FE model predicts the ultimate failure compressive stress close to 85 of the mean experimental compressive strength value.

In this paper we have studied the flow of a micropolar fluid, whose constitutive equations were given by Eringen, in two dimensional plane flow. In two notes, we have discussed the validity of the boundary condition v=a ω and its effect on the entire flow field. We have restricted our study to the case when Stokes' approximation is valid, i. e. slow motion for it is difficult to uncouple the equations in the most general case.

Enchanted by Sources. Henry Biaudet, Liisi Karttunen and Finnish Historical Research in Rome in the Early Twentieth Century This study traces the scholarly endeavours of Henry Biaudet (1870 1915) and Liisi Karttunen (1880 1957) and "La mission historique finlandaise à Rome" which they founded in 1909. They are forgotten in Finnish historiography, but remain internationally renowned for their contribution to the nunciature studies. By investigating their historical work on the Counter- Reformation era, their roles in the scientific communities of Helsinki and Rome as well as the intersection of politics and science in their scholarly practices the study explores the nature of historical research in general at the turn of the twentieth century. The work covers fields such as historiography, university history and the political use of history. Methodologically the research is based on the analysis and contextualization of published and unpublished sources (e.g. correspondences, university records, scholarly publications and reviews in academic journals). Henry Biaudet criticized the previous research on the Nordic Counter-Reformation for its narrow national scope and sources. He sought out a new approach, including the use of sources in archives all over Europe and the inclusion of the Catholic viewpoint. Accordingly, Biaudet and Karttunen searched for records in archives in Southern Europe. Their unorthodox interpretations were denounced in Finland since the picture they gave of late sixteenth-century Sweden was too different from the national narrative. Moreover, Finnish national identity was firmly rooted in Protestantism, and questioning the benevolence of the Reformation and its main actors was considered as an attack not only against historical truth but also national values. The comparison between Biaudet s and Karttunen s arguments and the accepted narrative in Finland shows how traditional interpretations of the Nordic Reformation were influenced by the Lutheran ethos and European anticlerical rhetoric. Historians have recently paid substantial attention to the political use of history, usually focusing on politicized constructions of the national past. This study shows how research that met the criteria of modern historiography also served political purposes. Conducting research in an international community of historians and publishing ambitious scholarly studies that interested an international audience were ways to create a positive image of Finland abroad. These were not uniquely Finnish ideas but rather ideas shared by the international community of historians in Rome. In this context, scientific pursuits were given a clear political meaning. This enhances our understanding of nineteenth-century historiography being firmly rooted between science and politics.
