From Habits to Social Structures : Pragmatism and Contemporary Social Theory

Pragmatism has sometimes been taken as a catchphrase for epistemological stances in which anything goes. However, other authors argue that the real novelty and contribution of this tradition has to do with its view of action as the context in which all things human take place. Thus, it is action rather than, for example, discourses that should be our starting point in social theory. The introductory section of the book situates pragmatism (especially the ideas of G. H. Mead and John Dewey) within the field and tradition of social theory. This introductory also contextualizes the main core of the book which consists of four chapters. Two of these chapters have been published as articles in scientific journals and one in an edited book. All of them discuss the core problem of social theory: how is action related to social structures (and vice versa)? The argument is that habitual action is the explanation for the emergence of social structures from our action. Action produces structures and social reproduction takes place when action is habitualized; that is, when we develop social dispositions to act in a certain manner in familiar environments. This also means that even though the physical environment is the same for all of us, our habits structure it into different kinds of action possibilities. Each chapter highlights these general insights from different angles. Practice theory has gained momentum in recent years and it has many commonalities with pragmatism because both highlight the situated and corporeal character of human activity. One famous proponent of practice theory is Margaret Archer who has argued that the pragmatism of G. H. Mead leads to an oversocialized conception of selfhood. Mead does indeed present a socialized view of selfhood but this is a meta-sociological argument rather than a substantial sociological claim. Accordingly, one can argue that in this general sense intersubjectivity precedes subjectivity and not the other way around. Such a view does not indicate that our social relation would necessarily "colonize" individual action because there is a place for internal conversations (in Archer s terminology); it is especially in those phases of action where it meets obstacles due to the changes of the environment. The second issue discussed has the background assumption that social structures can fruitfully be conceptualized as institutions. A general classification of different institution theories is presented and it is argued that there is a need for a habitual theory of institutions due to the problems associated with these other theories. So-called habitual institutionalism accounts for institutions in terms of established and prevalent social dispositions that structure our social interactions. The germs of this institution theory can be found in the work of Thorstein Veblen. Since Veblen s times, these ideas have been discussed for example, by the economist Geoffrey M. Hodgson. His ideas on the evolution of institutions are presented but a critical stance is taken towards his tendency of defining institutions with the help of rules because rules are not always present in institutions. Accordingly, habitual action is the most basic but by no means the only aspect of institutional reproduction. The third chapter deals with theme of action and structures in the context of Pierre Bourdieu s thought. Bourdieu s term habitus refers to a system of dispositions which structure social fields. It is argued that habits come close to the concept of habitus in the sense that the latter consists of particular kinds of habits; those that are related to the reproduction of socioeconomic positions. Habits are thus constituents of a general theory of societal reproduction whereas habitus is a systematic combination of socioeconomic habits. The fourth theme relates to issues of social change and development. The capabilities approach has been associated with the name of Amartya Sen, for example, and it underscores problems inhering in economistic ways of evaluating social development. However, Sen s argument has some theoretical problems. For example, his theory cannot adequately confront the problem of relativism. In addition, Sen s discussion lacks also a theory of the role of the public. With the help of arguments derived from pragmatism, one gets an action-based, socially constituted view of freedom in which the role of the public is essential. In general, it is argued that a socially constituted view of agency does not necessarily to lead to pessimistic conclusions about the freedom of action.

Medieberättelser om den politiska retoriken om invandring - Hur konstrueras vår bild av invandring genom nyhetsrapportering?

I min pro gradu-avhandling undersöker jag hur media bidrar till att konstruera bilden av invandring till Finland. Mitt material består av tre nationella tidningar, varav Helsingin Sanomat och Huvudstadsbladet representerar dagstidningar och Iltalehti kvällspressen. Bakgrunden för undersökningen är en tre månaders period under vintern 2008-2009, då invandring låg högt på den politiska agendan. Under denna period skärptes den politiska retoriken mot invandring. Detta tillskrivs främst sannfinländarnas valframgång i kommunalvalet hösten 2008. Materialet består av s.k. hårda nyheter om invandring från tidningarnas inrikessidor samt åsiktsjournalistik i form av ledare och kolumner. Tidigare forskning i medierapportering om invandring och den finländska politiska debatten om invandring utgör den teoretiska bakgrunden för avhandlingen. Långvariga kartläggningsprojekt av medierapporteringen om invandring har utförts av Centret för forskning om etniska relationer och nationalism, gällande finlandssvenska tidningar (se Haavisto 2007) och av Journalismin tutkimuskeskus, gällande finskspråkiga tidningar (se Raittila & Vehmas 2005). Dessa utgör bakgrundskunskap som jag bygger vidare på. Andra viktiga källor är Kaarina Horstis (2005) avhandling, som handlar om medierapporteringen om asylsökande och mångkulturalism och Outi Lepolas (2008) avhandling gällande riksdagsdebatter om invandring och mångkulturalism på 1990-talet. I analysen använder jag kritisk diskursanalys, men tar inslag ur ramanalys och retorikanalys. Ett centralt begrepp i min avhandling är nyhetsgenre och jag undersöker hur nyhetens konventioner påverkar sättet på vilket frågor om invandring presenteras. Media bygger upp olika tolkningar av den sociala verkligheten genom att beskriva berättelser. Jag analyserar rapporteringen av den politiska debatten ur detta perspektiv och ser på vilka talarpositioner ges åt de olika politiska aktörerna i debatten. I rapporteringen om invandrargruppers ankomst till Finland var en krisinramning dominerande. Genom negativa metaforer konstrueras invandring som ett hot mot det finska samhället. Frågan om asylsökande, framom andra invandrargrupper, får mycket utrymme i tidningarna och bidrar till att rama in diskussionen om invandring i stort. I rapporteringen om den politiska debatten från perioden förekommer tillspetsad retorik mot invandring också från politiker ur de stora partierna. Genom denna retorik konstruerar man invandring som ett hot. Denna retorik tillhör den invandrarkritiska diskursen. Andra diskurser genom vilka man behandlar invandring i materialet är den arbetsrelaterade diskursen och den mångkulturella diskursen. Argument som stödjer sig mot dessa diskurser är dock mycket färre och hamnar i skymundan av den invandrarkritiska diskursen.

An Axiom of Military Law : Applicability of National Criminal Law to Military Personnel and Associated Civilians Abroad

States regularly deploy elements of their armed forces abroad. When that happens, the military personnel concerned largely remain governed by the penal law of the State that they serve. This extraterritorial extension of national criminal law, which has been treated as axiomatic in domestic law and ignored by international law scholarship, is the subject of this dissertation. The first part of the study considers the ambit of national criminal law without any special regard to the armed forces. It explores the historical development of the currently prevailing system of territorial law and looks at the ambit that national legal systems claim today. Turning then to international law, the study debunks the oddly persistent belief that States enjoy a freedom to extend their laws to extraterritorial conduct as they please, and that they are in this respect constrained only by some specific prohibitions in international law. Six arguments historical, empirical, ideological, functional, doctrinal and systemic are advanced to support a contrary view: that States are prohibited from extending the reach of their legal systems abroad, unless they can rely on a permissive principle of international law for doing so. The second part of the study deals specifically with State jurisdiction in a military context, that is to say, as applied to military personnel in the strict sense (service members) and various civilians serving with or accompanying the forces (associated civilians). While the status of armed forces on foreign soil has transformed from one encapsulated in the customary concept of extraterritoriality to a modern regulation of immunities granted by treaties, elements of armed forces located abroad usually do enjoy some degree of insulation from the legal system of the host State. As a corollary, they should generally remain covered by the law of their own State. The extent of this extraterritorial extension of national law is revealed in a comparative review of national legislation, paying particular attention to recent legal reforms in the United States and the United Kingdom two states that have sought to extend the scope of their national law to cover the conduct of military contractor personnel. The principal argument of the dissertation is that applying national criminal law to service members and associated civilians abroad is distinct from other extraterritorial claims of jurisdiction (in particular, the nationality principle or the protective principle of jurisdiction). The service jurisdiction over the armed forces has a distinct aim: ensuring the coherence and indivisibility of the forces and maintaining discipline. Furthermore, the exercise of service jurisdiction seeks to reduce the chances of the State itself becoming internationally liable for the conduct of its service members and associated civilians. Critically, the legal system of the troop-deploying State, by extending its reach abroad, seeks to avoid accountability gaps that might result from immunities from host State law.

Global Processes, Local Strategies : migration of educated Dominicans.

The aim of this thesis is to examine migration of educated Dominicans in light of global processes. Current global developments have resulted in increasingly global movements of people, yet people tend to come from certain places in large numbers rather than others. At the same time, international migration is increasingly selective, which shows in the disproportional number of educated migrants. This study discovers individual and societal motivations that explain why young educated Dominicans decide to migrate and return. The theoretical framework of this thesis underlines that migration is a dynamic process rooted in other global developments. Migratory movements should be seen as a result of interacting macro- and microstructures, which are linked by a number of intermediate mechanisms, meso-structures. The way individuals perceive opportunity structures concretises the way global developments mediate to the micro-level. The case of the Dominican Republic shows that there is a diversity of local responses to the world system, as Dominicans have produced their own unique historical responses to global changes. The thesis explains that Dominican migration is importantly conditioned by socioeconomic and educational background. Migration is more accessible for the educated middle class, because of the availability of better resources. Educated migrants also seem less likely to rely on networks to organize their migrations. The role of networks in migration differs by socioeconomic background on the one hand, and by the specific connections each individual has to current and previous migrants on the other hand. The personal and cultural values of the migrant are also pivotal. The central argument of this thesis is that a veritable culture of migration has evolved in the Dominican Republic. The actual economic, political and social circumstances have led many Dominicans to believe that there are better opportunities elsewhere. The globalisation of certain expectations on the one hand, and the development of the specifically Dominican feeling of ‘externalism’ on the other, have for their part given rise to the Dominican culture of migration. The study also suggests that the current Dominican development model encourages migration. Besides global structures, local structures are found to ve pivotal in determining how global processes are materialised in a specific place. The research for this thesis was conducted by using qualitative methodology. The focus of this thesis was on thematic interviews that reveal the subject’s point of view and give a fuller understanding of migration and mobility of the educated. The data was mainly collected during a field research phase in Santo Domingo, the Dominican Republic in December 2009 and January 2010. The principal material consists of ten thematic interviews held with educated Dominican current or former migrants. Four expert interviews, relevant empirical data, theoretical literature and newspaper articles were also comprehensively used.

Paradigms in Statistical Inference for Finite Populations; Up to the 1950s

Modern sample surveys started to spread after statistician at the U.S. Bureau of the Census in the 1940s had developed a sampling design for the Current Population Survey (CPS). A significant factor was also that digital computers became available for statisticians. In the beginning of 1950s, the theory was documented in textbooks on survey sampling. This thesis is about the development of the statistical inference for sample surveys. For the first time the idea of statistical inference was enunciated by a French scientist, P. S. Laplace. In 1781, he published a plan for a partial investigation in which he determined the sample size needed to reach the desired accuracy in estimation. The plan was based on Laplace s Principle of Inverse Probability and on his derivation of the Central Limit Theorem. They were published in a memoir in 1774 which is one of the origins of statistical inference. Laplace s inference model was based on Bernoulli trials and binominal probabilities. He assumed that populations were changing constantly. It was depicted by assuming a priori distributions for parameters. Laplace s inference model dominated statistical thinking for a century. Sample selection in Laplace s investigations was purposive. In 1894 in the International Statistical Institute meeting, Norwegian Anders Kiaer presented the idea of the Representative Method to draw samples. Its idea was that the sample would be a miniature of the population. It is still prevailing. The virtues of random sampling were known but practical problems of sample selection and data collection hindered its use. Arhtur Bowley realized the potentials of Kiaer s method and in the beginning of the 20th century carried out several surveys in the UK. He also developed the theory of statistical inference for finite populations. It was based on Laplace s inference model. R. A. Fisher contributions in the 1920 s constitute a watershed in the statistical science He revolutionized the theory of statistics. In addition, he introduced a new statistical inference model which is still the prevailing paradigm. The essential idea is to draw repeatedly samples from the same population and the assumption that population parameters are constants. Fisher s theory did not include a priori probabilities. Jerzy Neyman adopted Fisher s inference model and applied it to finite populations with the difference that Neyman s inference model does not include any assumptions of the distributions of the study variables. Applying Fisher s fiducial argument he developed the theory for confidence intervals. Neyman s last contribution to survey sampling presented a theory for double sampling. This gave the central idea for statisticians at the U.S. Census Bureau to develop the complex survey design for the CPS. Important criterion was to have a method in which the costs of data collection were acceptable, and which provided approximately equal interviewer workloads, besides sufficient accuracy in estimation.

Gadamers hermeneutik och naturvetenskaplig experimentering

I detta arbete undersöks naturvetenskaplig kunskap ur ett filosofiskt perspektiv. Arbetets centrala ämne är det naturvetenskapliga experimenterandets praktiska aspekter och deras anknytningar till den teoretiska naturvetenskapliga kunskapen. Ämnet behandlas med hjälp av Hans-Georg Gadamers hermeneutiska filosofi i boken Wahrheit und Methode. Gadamers utgångspunkt i denna bok är att hermeneutiken beskriver vad som händer i texttolkning då en tolkare förstår en skriven text, men han antyder också att hermeneutiken har vidare tillämpningsområden, till och med att den universalt beskriver alla former av mänsklig förståelse. Syftet med detta arbete är att undersöka hur Gadamers hermeneutik kan tillämpas på naturvetenskaplig förståelse och vilka ändringar man då måste införliva i hermeneutiken samt att skissa grunddragen för en hermeneutisk modell av naturvetenskaplig kunskap. I arbetet presenteras först de centrala elementen i Gadamers hermeneutiska filosofi, speciellt föromdömens positiva inverkan på tolkandet och den verkningshistoriska effekten bakom varje tolkning. Sedan diskuteras bristerna i Gadamers argument för hermeneutikens universalitet, speciellt hans starka betoning av språket som grunden för all förståelse. Om Gadamers hermeneutik skall kunna tillämpas på naturvetenskapens område måste även observationer kunna vara föremål för tolkning. De dominanta trenderna i vetenskapsfilosofin då Gadamer skrev Wahrheit und Methode är en förklaring till att Gadamer starkt förbinder sig till textförståelsen och oftast diskuterar den naturvetenskapliga kunskapen endast som en negativ motpol till den humanvetenskapliga. Vetenskapsfilosofins utveckling efter Wahrheit und Methode, speciellt det faktum att fullständig objektivitet inte mera anses vara ett realistiskt ideal, höjer förväntningarna på hermeneutikens värde för naturvetenskapernas filosofi. Till följande diskuteras tre bidrag till naturvetenskapernas filosofi som är speciellt värdefulla för en hermeneutiken. Den första av dessa är Sylvain Brombergers analys av ovisshet i vetenskapliga undersökningar. Bromberger hävdar att vetenskaplig forskning riktas mot frågor vars svar forskaren inte kan föreställa sig på förhand. Brombergers analys tyder på att det finns en hermeneutisk dialektik av frågor och svar i naturvetenskapliga experiment där forskaren strävar till att göra observationer för att besvara sina frågor. Det andra bidraget är Michael Polanyis studie av den praktiska och personliga kunskapens betydelse för all vetenskaplig forskning. Här är speciellt det vetenskapliga språkets utveckling i samband med experimentering av intresse. Det tredje bidraget är Robert Creases studie av experimentella observationer som visar att observationstolkning innefattar många element som kan förknippas med hermeneutiken. Analysen av de tre ovannämnda studierna leder till följande slutsatser. Den naturvetenskapliga forskningens hermeneutiska element förväntas vara starkt framför allt i experimentell forskning där forskaren utreder nya frågor i en kontinuerlig dialog av tekniskt prövande, praktisk identifiering och språklig beskrivning av nya fenomen. Speciellt beaktansvärd är skillnaden mellan verifierande och upptäckande naturvetenskapliga undersökningar. Tidigare resultat kan verifieras med hjälp av mätningar som specificeras på förhand, men ingen kan på förhand specificera de tekniska och språkliga steg som krävs för ett framgångsrikt upptäckande experiment. Experimentella upptäckter kräver därför en praktisk kunskap som inte kan reduceras till ren teori eller metodologi. Denna praktiska kunskap kan beskrivas med hjälp av Gadamers hermeneutik. Till sist diskuteras vissa grundläggande drag som kan sägas vara karakteristiska för en hermeneutisk modell av naturvetenskaplig kunskap. Speciellt den naturvetenskapliga kunskapens historiska natur, fördomarnas betydelse i naturvetenskaplig forskning samt vikten av forskarens personliga perspektiv i den naturvetenskapliga observationen är viktiga stöttestenar som gör att den hermeneutiska naturvetenskapsmodellen skiljer sig betydligt från modeller som betonar naturvetenskapernas objektivitet. Men det hermeneutiska perspektivet utesluter inte nödvändigtvis andra perspektiv. Dess huvudsakliga nytta är att den tillåter oss att undersöka sidor av naturvetenskaplig kunskap som objektivitetsbetonande modeller lämnar alltför mycket i skymundan. Till dessa hör speciellt det praktiska arbetet i naturvetenskaplig experimentering.

Autoimmune Regulator (AIRE) in the Maintenance of Immunological Tolerance

Autoimmune regulator (AIRE) is the gene mutated in the human polyglandular autoimmune disease called Autoimmune polyendocrinopathy, candidiasis, and ectodermal dystrophy (APECED) that belongs to the Finnish disease heritage. Murine Aire has been shown to be important in the generation of the T cell central tolerance in the thymus by promoting the expression of ectopic tissue-specific antigens in the thymic medulla. Aire is also involved in the thymus tissue organization during organogenesis. In addition to the thymus, AIRE/Aire is expressed in the secondary lymphoid organs. Accordingly, a role for AIRE/Aire in the maintenance of peripheral tolerance has been suggested. Peripheral tolerance involves mechanisms that suppress immune responses in secondary lymphoid organs. Regulatory T cells (Tregs) are an important suppressive T cell population mediating the peripheral tolerance. Tregs are generated in the thymus but also in the peripheral immune system T cells can acquire the Treg-phenotype. The aim of this study was to characterize Tregs in APECED patients and in the APECED mouse model (Aire-deficient mice). In the mouse model, it was possible to separate Aire expression in the thymus and in the secondary lymphoid organs. The relative importance of thymic and peripheral Aire expression in the maintenance of immunological tolerance was studied in an experimental model that was strongly biased towards autoimmunity, i.e. lymphopenia-induced proliferation (LIP) of lymphocytes. This experimental model was also utilised to study the behaviour of T cells with dual-specific T cell receptors (TCR) during the proliferation. The Treg phenotype was studied by flow cytometry and relative gene expression with real-time polymerase chain reaction. TCR repertoires of the Tregs isolated from APECED patients and healthy controls were also compared. The dual-specific TCRs were studied with the TCR repertoire analysis that was followed with sequencing of the chosen TCR genes in order to estimate changes in the dual-specific TCR diversity. The Treg function was tested with an in vitro suppression assay. The APECED patients had normal numbers of Tregs but the phenotype and suppressive functions of the Tregs were impaired. In order to separate Aire functions in the thymus from its yet unknown role in the secondary lymphoid organs, the phenomenon of LIP was utilised. In this setting, the lymphocytes that are adoptively transferred to a lymphopenic recipient proliferate to stimuli from self-originating antigens. This proliferation can result in autoimmunity if peripheral tolerance is not fully functional. When lymphocytes that had matured without Aire in the thymus were transferred to lymphopenic Aire-sufficient recipients, no clinical autoimmunity followed. The Aire-deficient donor-originating lymphocytes hyperproliferated, and other signs of immune dysregulation were also found in the recipients. Overt autoimmunity, however, was prevented by the Aire-deficient donor-originating Tregs that hyperproliferated in the recipients. Aire-deficient lymphopenic mice were used to study whether peripheral loss of Aire had an impact on the maintenance of peripheral tolerance. When normal lymphocytes were transferred to these Aire-deficient lymphopenic recipients, the majority of recipients developed a clinically symptomatic colitis. The colitis was confirmed also by histological analysis of the colon tissue sections. In the Aire-deficient lymphopenic recipients Tregs were proliferating significantly less than in the control group s recipients that had normal Aire expression in their secondary lymphoid organs. This study shows that Aire is not only important in the central tolerance but is also has a significant role in the maintenance of the peripheral tolerance both in mice and men. Aire expressed in the secondary lymphoid organs is involved in the functions of Tregs during an immune response. This peripheral expression appears to be relatively more important in some situations since only those lymphopenic recipients that had lost peripheral expression of Aire developed a symptomatic autoimmune disease. This AIRE-related Treg defect could be clinically important in understanding the pathogenesis of APECED.

Whose ETSIP? National and local ownership of Namibia's education and training sector improvement programme

Tämä työ tarkastelee kansallista ja paikallista omistajuutta Namibian opetussektorin kehittämisohjelmassa. Opetussektorin kehittämisohjelma ETSIP on 15-vuotinen sektoriohjelma vuosille 2005-2015 ja sen tavoitteena on edesauttaa Namibian kehittymistä tietoyhteiskunnaksi. Tutkimuksen tarkoituksena on selvittää miten kansallinen ja paikallinen omistajuus on toteutunut ETSIP prosessin aikana. Erityisesti pyritään selvittämään paikallistason opetussektorin virkamiesten näkemyksiä ETSIP prosessista, heidän roolistaan siinä ja siitä millaisia vaikuttamisen ja hallinnan mahdollisuuksia heillä on ollut prosessin aikana. Tutkimuksen lähtökohta on laadullinen ja lähestymistapa konstruktionistinen: tutkimus tarkastelee todellisuutta ihmisten kokemusten, näkemysten ja toiminnan kautta. Tutkimusaineisto koostuu haastatteluista, epävirallisista keskusteluista, lehtiartikkeleista ja ETSIP dokumenteista. Tutkimus osoittaa että kansallinen omistajuus on epämääräinen käsite sillä kansallisia toimijoita ja näkemyksiä on useita. Tutkimus vahvistaa Castel-Brancon huomion siitä, että omistajuutta on tarkasteltava kontekstissaan: muuttuvana ja kilpailtuna. ETSIPin rinnalle ollaan valmistelemassa uutta strategista ohjelmaa opetusministeriölle mikä saattaa muuttaa omistajuutta ETSIPiin. ETSIP dokumenttien omistajuusretoriikka myötäilee kansainvälisiä sitoumuksia avun vaikuttavuuden parantamiseksi mutta niistä puuttuu syvällisempi analyysi siitä, miten kansallinen ja paikallinen omistajuus toteutuisi käytännössä. Avunantajien näkemys omistajuudesta on suppea: omistajuus nähdään lähinnä sitoutumisena ennalta määrättyyn politiikkaohjelmaan. Haastatteluaineistosta nousee esiin Whitfieldin ja Frazerin jaottelu suppeista ja laajoista omistajuuskäsityksistä. Sitoutumista ETSIP ohjelmaan pidetään tärkeänä mutta riittämättömänä määritteenä omistajuudelle. Paikallisella tasolla sitoutuminen ETSIP ohjelman periaatteisiin ja tavoitteisiin on toteutunut melko hyvin mutta jos omistajuutta tarkastellaan laajemmin vaikutusvallan ja hallinnan käsitteiden kautta voidaan todeta että omistajuus on ollut heikkoa. Paikallisella tasolla ei ole ollut juurikaan vaikutusvaltaa ETSIP ohjelman sisältöön eikä mahdollisuutta hallita ohjelman toteutusta ja päättää siitä mitä hankkeita ohjelman kautta rahoitetaan. Tujanin demokraattisen omistajuuden käsite kuvaa tarvetta muuttaa ja laajentaa omistajuusajattelua huomioiden paikallisen tason paremmin. Tämä tutkimus viittaa siihen että omistajuuden toteutuminen paikallisella tasolla edellyttäisi institutionaalisen kulttuurin muutosta ja institutionaalisen legitimiteetin vahvistamista. Omistajuuden mahdollistamiseksi paikallisella tasolla tarvittaisiin poliittista johtajuutta, luottamusta, vastuullisuuden kulttuurin kehittämistä, tehokkaampaa tiedonjakoa, laajaa osallistumista, vuoropuhelua ja yhteistyötä. Ennen kaikkea tarvittaisiin paikallisen tason vaikutusvaltaa päätöksenteossa ja kontrollia resurssien käytöstä. Tälle muutokselle on selvä tarve ja tilaus.

Diffraction of a cylindrical pulse by a half plane under mixed boundary conditions

The general time dependent source problem has been solved by the method of transforms (Laplace, Lebedev–Kontorovich in succession) and the solution is obtained in the form of an infinite series involving Legendre functions. The solutions in the case of harmonic time dependence and the incident plane wave have been derived from the above solution and are presented in the form of an infinite series. In the case of an incident plane wave, the series has been summed and the final solution involves an improper integral which behaves like a complementary error function for large values of the argument. Finally, the far field evaluation has been shown. The results are compared with those of Sommerfeld's half-plane diffraction problem with unmixed boundary conditions.

Tavallisuudesta tyylikkyyteen? : Sukupuoli ja maku kodinmuutosohjelmissa

The study focuses on the Finnish home makeover shows Inno (2004 , Nelonen) and Kodin kääntöpiiri (2001 2005; YLE TV2) and their episodes broadcast in spring 2004. The research material also includes the websites of both shows and messages concerning Inno from an online discussion forum. As people decorate their homes and reflect on them, they engage in negotiations of taste and in the construction of the ideal self. The main question of the study is: how are representations of the gendered self produced in home makeover shows? The broader theoretical and methodological context of the study is based on intersectionality, or simultaneous study of different identity categories. In this study, the main focus is on the intersections of gender, class and sexuality. Hence, the secondary research question is: how do ways of doing gender intersect with producing the ideas of class and sexuality in the representations of home makeover shows? The theoretical framework of the study combines Judith Butler s theory of gender performativity and Pierre Bourdieu s theory of taste. The analysis is founded upon a close reading focusing on the details and ambiguous meanings contained in the televisual representation. Home makeover shows are explored as a part of contemporary television culture, which is characterised by a significant increase in the number of both television channels and global television formats, as well as the hybridisation of programme types. Researchers on lifestyle television have paid attention to male designers and their ability to reconstruct meanings related to domesticity and home decoration as feminine spheres. The dissertation contributes to this discussion by analysing the representations of the male interior decorator in Inno and the four female interior decorators in Kodin kääntöpiiri. The focus is on the professional self and how it is both gendered and defined as an arbiter of taste. The programme concepts produce the impression that the makeover homes and their occupants are ordinary . The manufactured sense of ordinariness often conceals differences between the participants. One argument of the study is that the ordinariness of participants on lifestyle television should not be taken for granted without further reflection on the implications of labeling something as ordinary. Updating of interior decoration in home makeover shows can be interpreted as an area of doing gender that requires deliberation, effort, expert knowledge and a sufficient budget. The ideal lay decorator is portrayed as culturally omnivorous, brave and receptive to new ideas. The ability to reflect on ways of representing masculinity and femininity through decoration is also implied. In home makeover shows, greater self-awareness regarding the ways in which gender is produced does not lead to repeating gender differently. The idea of normative heterosexuality is in a hegemonic position in the representations of the participants. In Inno and Kodin kääntöpiiri questions of class are not made explicit. However, the idea of class is produced indirectly e.g. by describing the apartments and houses of the participants, by discussing their hobbies or interest in cultural products. In Inno, home decoration is primarily depicted as an individualistic consumer choice, while in Kodin kääntöpiiri it is often defined as a way to strengthen the ties of nuclear families. In Kodin kääntöpiiri, the ethos of familism is combined with pleasures gained from consumption and DIY activities. As a whole, the multidisciplinary study indicates a great number of differences between the two shows.

Una gramática descriptiva del chabacano de Ternate

This dissertation is a descriptive grammar of Ternate Chabacano, a Spanish-lexifier Creole spoken by 3.000 people in the town of Ternate, Philippines. The dissertation offers an analysis of the phonological, morphological, and syntactic system of the language. It includes an overview of the historical background, the current situation of the speech community and a collection of annotated texts. Ternate Chabacano shares many characteristics with its main adstrate language Tagalog as well as the dialectal varieties of Spanish. At present, English also exerts an influence, nevertheless mainly affecting its lexicon. The description offered is based on fieldwork conducted in Ternate. Spoken language collected through thematic interviews forms the main type of the material analysed. Information regarding the informants and text types is included in the examples. Ternate Chabacano has a five-vowel system and 17 consonant phonemes. The morphology of the language is largely isolating. Clitics are used extensively for expressing adverbial relations. The verbal system is based on the preverbal markers that express the category of tense, modality and aspect, among which aspect is the main dimension. Complex predicates and verbal chains are used in order to further distinguish aspect and modality, as well as changes of voice and valency. Intransitive verbs express motion, states, and reflexive actions, even though the majority of verbs can occur in both intransitive and transitive clauses. Ternate Chabacano is a nominative-accusative type language but the typological configuration of the Philippine languages influences the marking of its constituents. A case in point is constituted by the nominal determination system. The basic constituent order in a clause is VSO. Equative and attibutive clauses are formed by juxtaposition while the locative clauses feature a copula. Indefinite terms are expressed through existential constructions. The negation of existential clauses differs from standard negation but both are intensified in the same way. In spoken discourse, tag-questions are common. Pragmatic elements and social formulas reflect largely the corresponding Tagalog expressions. Coordination and subordination occur typically without overt markers but a variety of markers exists for expressing different relations, especially those made explicit by adverbial clauses. Verbal chains form a continuum from serial verbs to complementation and ultimately to coordination.

The Biopolitics of Gender

This dissertation inquires into the relationship between gender and biopolitics. Biopolitics, according to Michel Foucault, is the mode of politics that is situated and exercised at the level of life. The dissertation claims that gender is a technology of biopower specific to the optimisation of the sexual reproduction of human life, deployed through the scientific and governmental problematisation of declining fertility rates in the mid-twentieth century. Just as Michel Foucault claimed that sexuality became a scientific and political discourse in the nineteenth century, gender has also since emerged in these fields. In this dissertation, gender is treated as neither a representation of sex nor a cultural construct or category of identity. Rather, a genealogy of gender as an apparatus of biopower in conducted. It demonstrates how scientific and theoretical developments in the twentieth century marshalled gender into the sex/sexuality apparatus as a new technology of liberal biopower. Gender, I argue, has become necessary for the Western liberal order to recapture and re-optimise the life-producing functions of sex that reproduce the very object of biopolitics: life. The concept of the life function is introduced to analyse the life-producing violence of the sex/sexuality/gender apparatus. To do this, the thesis rereads the work of Michel Foucault through Gilles Deleuze for a deeper grasp of the material strategies of biopower and how it produces categories of difference and divides population according to them. The work of Judith Butler, in turn, is used as a foil against which to rearticulate the question of how to examine gender genealogically and biopolitically. The dissertation then executes a genealogy of gender, tracing the changing rationalities of sex/sexuality/gender from early feminist thought, through mid-twentieth century sexological, feminist, and demographic research, to current EU policy. According to this genealogy, in the mid-twentieth century demographers perceived that sexuality/sex, which Foucault observed as the life-producing biopolitical apparatus, was no longer sufficiently disciplining human bodies to reproduce. The life function was escaping the grasp of biopower. The analysis demonstrates how gender theory was taken up as a means of reterritorialising the life function: nature would be disciplined to reproduce by controlling culture. The crucial theoretical and genealogical argument of the thesis, that gender is a discourse with biopolitical foundations and a technology of biopower, radically challenges the premises of gender theory and feminist politics, as well as the emancipatory potential often granted to the gender concept. The project asks what gender means, what biopolitical function it performs, and what is at stake for feminist politics when it engages with it. In so doing, it identifies biopolitics and the problem of life as possibly the most urgent arena for feminist politics today.

Optimal explicit guidance of multistage launch vehicle along three-dimensional trajectory

Details of an efficient optimal closed-loop guidance algorithm for a three-dimensional launch are presented with simulation results. Two types of orbital injections, with either true anomaly or argument of perigee being free at injection, are considered. The resulting steering-angle profile under the assumption of uniform gravity lies in a canted plane which transforms a three-dimensional problem into an equivalent two-dimensional one. Effects of thrust are estimated using a series in a recursive way. Encke's method is used to predict the trajectory during powered flight and then to compute the changes due to actual gravity using two gravity-related vectors. Guidance parameters are evaluated using the linear differential correction method. Optimality of the algorithm is tested against a standard ground-based trajectory optimization package. The performance of the algorithm is tested for accuracy, robustness, and efficiency for a sun-synchronous mission involving guidance for a multistage vehicle that requires large pitch and yaw maneuver. To demonstrate applicability of the algorithm to a range of missions, injection into a geostationary transfer orbit is also considered. The performance of the present algorithm is found to be much better than others.

Infrared divergences and confinement in massive (2+1)-dimensional QED

In (2+1)-dimensional quantum electrodynamics with massless photons and massive matter fields, it is shown that the mass renormalization of the latter is infrared divergent at one loop. This result remains unchanged at two loops. A simple argument based on a similar divergence of the Coulomb potential leads us to conjecture that charged states are not observable in this model. This argument holds in 1+1 dimensions also.

Det grekiska dramat. En Studie av euroländeras agerande i Greklandskrisen.

Jag granskar i min avhandling pro gradu den ekonomiska krisen i Grekland som kulminerade under vären 2010 när Grekland vände sig tili de övriga medlemsländerna i Ekonomiska och monetära Unionen (EMU) med en förfrägan om ekonomisk hjälp i formav län. Syftet med avhandlingen är att undersöka hur de övriga EMU-medlemmarna fattade sitt beslut om att ekonomiskt stöda Grekland efter att landets kreditvärdighet sänkts av de internationella kreditvärderingsinstituten. Jag granskar Greklandskrisen och dess utveckling, de lösningar som man gick in för inom ramen för valutaunionen, hur besluten om stödpaketet fattades och vilka faktorer som päverkade besluten. Jag tar avstamp i Optimum Currency Area-teorin (OCA-teorin) och teorier om europeisk ekonomisk integration. Dessutom för jag en diskussion kring solidariteten mellan EUländerna, som ocksä använts som argument för stödpaketet tili Grekland. Jag klassificerar euroländerna utgäende för hur det nationella beslutet om Greklandspaketet fattats och gör därefter en agglomerativ klusteranalys, med ambitionen att förklara vilka faktorer som päverkat besluten. Syftet med klusteranalysen är att klargöra huruvida politiska faktorer, som härrör sig tili regeringen och dess sammansättning, eller ekonomiska faktorer, som bclyser statsfinansernas tillständ, bäst förklarar hur ett land fattat sitt beslut. Resultatet visar att de politiska variablerna har päverkat ländernas beslut mer an de ekonomiska, men förklaringsgraden är relativt lag i bägge fallen. Jag för vidare en diskussion om resultatet ur ett OCA-perspektiv, kriterierna för ett optimalt valutaomräde samt EMU:s utveckling i dito riktning. Jag avslutar avhandlingen med en diskussion kring EMU:s framtid.
