Idén om en karriär - ett kulturellt manuskript för skapandet av det postmoderna självet:

Bakgrunden till denna undersökning utgörs av arbetslivets förändring och dess konsekvenser för konstrueringen av självidentiteten; hur avväger unga konsulter i början av sin karriär mellan olika diskurser för att skapa en förhandlad självidentitet som styrs av idén om en karriär och såvida är hållbar även i ett långtidsperspektiv? Undersökningen tar avstamp i de sociologiska diskussionerna om informationssamhällets framväxt och dess inverkan på arbetets karaktär. Undersökningen utgår från begreppet kunskapsarbete (Alvesson 2001; Blom, Melin & Pyöriä 2001) eftersom konsultyrket kan anses representera denna typ av arbete. Ett genomgående tema är flexibiliteten och det höga tempot som å ena sidan möjliggör självförverkligande men å andra sidan försvårar skapandet av en sammanhängande självidentitet (Sennett 2002). Denna problematik är viktigt att ta i beaktande då förlängandet av arbetskarriärerna och ökandet av arbetslivets attraktivitet blivit centrala mål för den finska samhällspolitiken (Julkunen & Pärnänen 2005) samtidigt som ett generationsskifte håller på att ske på den finländska arbetsmarknaden. Undersökningen utgår från idén om karriären som ett manuskript som ger upphov för identitetsförhandlingar och sammanbinder livets olika domäner till ett personligt liv inte bara i nuläget utan även i ett långtidsperspektiv. Enligt Alvesson & Willmot (2002) framkallas identitetsförhandlingar genom både samhälleliga och organisationsspecifika identitetsreglerande praktiker. Jag utgår från antagandet att självidentiteten fungerar som den sammanbindande knytpunkten mellan karriären och det övriga livet, vilket gör det intressant att koncentrera sig på de identitetsförhandlingar som informanterna utsätts för i förhållande till sitt arbete och idén om en karriär. Begreppet personligt liv ger utrymme för individuell aktivitet och personliga betydelser men behåller ändå föreställningen om individen som inbäddad och sammanbunden i och med det sociala och kulturella (Smart 2007). I bakgrunden finns teorierna om den nya form som makten antagit i organisationer (Foucault; Rose 1999; Grey 1994, Casey 1995) och förvandlat individen till en ett självstyrande subjekt som arbetar som en entreprenör (Rose 1999). Jag poängterar den subjektiva aspekten av karriären som någonting som individen själv konstruerar (Hughes 1997; Barley 1989) och uppfattar i likhet med Julkunen (2003) och Acker (1990; 2006) ålder och kön som sociala kategorier i organisationsstrukturen. Syftet med denna studie är att undersöka hur unga personer utför identitetsförhandlingar i förhållande till arbetet och idén om en karriär i nuläget, samt sammanbinder karriären, framtiden och livet över lag med sin självidentitet i ett karriärperspektiv. Jag har valt unga konsulter som forskningsobjekt, eftersom endast en liten del av den sociologiska arbetslivsforskningen intresserat sig för just unga. Konsultbranschen är ett intressant forskningsobjekt av samma orsak – denna bransch har behandlats i mycket liten skala i finländsk forskning. Det empiriska materialet består av kvalitativa intervjuer med unga, högutbildade män och kvinnor i konsultbranschen. Som analysmetod har jag använt mig av tema-analys inspirerad av diskursanalys. Genom att undersöka individers identitetsförhandlingar i ett karriärperspektiv hoppas jag kunna bidra med nya synpunkter och infallsvinklar samt bättre förståelse för det postindustriella arbetslivet som karakteriseras av kunskapsintensifiering och snabba förändringar i organisationer. Studien visar att idén om en karriär fungerar som ett medel för designandet av det postmoderna självet på samma sätt som till exempel konsumtionen av vissa varumärken. Enligt studien har den flexibla kapitalismen olika inverkan på män och kvinnors idéer om en karriär och betjänar den manliga karriären betydligt bättre än den kvinnliga, åtminstone så länge traditionella könskonstruktioner dominerar. För männen är det naturligt att totalt utesluta faderskapet från karriärkonstruktionen, vilket får dem att kapitulera inför organisationens krav. För kvinnorna är det lika naturligt att justera idén om den framtida karriären enligt möjliga barn i framtiden. Möjligheten att bejaka moderskapets krav verkar beskydda den kvinnliga självidentiteten från att totalt ge efter för organisationens försök att kontrollera subjektiviteten. De unga informanterna konstruerar sitt arbete i mycket annorlunda termer än vad som traditionellt förknippas med arbete; konsultarbetets projektbaserade karaktär konstrueras som äventyrligt, roligt, intressant och omväxlande. Eftersom avsaknad av långsiktighet och rutiner förknippas med den tid i livet då man är ung, underlättades sammanförandet av konsultarbetet med självidentiteten. Samtidigt visar studien hur svårt individen, som fungerar likt en entreprenör i förhållande till sin arbetsgivare, har att skilja mellan arbete och övrigt liv samtidigt som diskursen om balans mellan arbete och fritid dominerar i samhället. Detta ger upphov till en konstruktion av självet som en lycklig och autonom individ som är nöjd över sitt val av start på karriären och tycker om att jobba, medan de långa arbetsdagarna och kraven på ständig effektivitet och prestationer konstrueras som något naturligt. Slutligen efterlyser studien en omdefiniering av begreppet kunskapsarbete. Arbetssociologin i sin helhet har utgått från tanken om arbete som något ofrivilligt eller som tvång, medan informanterna i denna undersökning tvärtom konstruerar sitt arbete i termer som traditionellt förknippas med fritid och frivillighet . Man kan fråga sig ifall kunskapsarbetet håller på att slita sig loss från den traditionella uppfattningen om arbete och skapa en allt skarpare kontrast till det arbete som utförs i traditionell bemärkelse?

Embracing Integrability in Stellar and Planetary Dynamics

Hamiltonian systems in stellar and planetary dynamics are typically near integrable. For example, Solar System planets are almost in two-body orbits, and in simulations of the Galaxy, the orbits of stars seem regular. For such systems, sophisticated numerical methods can be developed through integrable approximations. Following this theme, we discuss three distinct problems. We start by considering numerical integration techniques for planetary systems. Perturbation methods (that utilize the integrability of the two-body motion) are preferred over conventional "blind" integration schemes. We introduce perturbation methods formulated with Cartesian variables. In our numerical comparisons, these are superior to their conventional counterparts, but, by definition, lack the energy-preserving properties of symplectic integrators. However, they are exceptionally well suited for relatively short-term integrations in which moderately high positional accuracy is required. The next exercise falls into the category of stability questions in solar systems. Traditionally, the interest has been on the orbital stability of planets, which have been quantified, e.g., by Liapunov exponents. We offer a complementary aspect by considering the protective effect that massive gas giants, like Jupiter, can offer to Earth-like planets inside the habitable zone of a planetary system. Our method produces a single quantity, called the escape rate, which characterizes the system of giant planets. We obtain some interesting results by computing escape rates for the Solar System. Galaxy modelling is our third and final topic. Because of the sheer number of stars (about 10^11 in Milky Way) galaxies are often modelled as smooth potentials hosting distributions of stars. Unfortunately, only a handful of suitable potentials are integrable (harmonic oscillator, isochrone and Stäckel potential). This severely limits the possibilities of finding an integrable approximation for an observed galaxy. A solution to this problem is torus construction; a method for numerically creating a foliation of invariant phase-space tori corresponding to a given target Hamiltonian. Canonically, the invariant tori are constructed by deforming the tori of some existing integrable toy Hamiltonian. Our contribution is to demonstrate how this can be accomplished by using a Stäckel toy Hamiltonian in ellipsoidal coordinates.

Choosing the Arranged One, Arranging the Chosen One – Imagining an Indian Modernity: Reconciling Love, Marriage and Family On and Off the Screen

This is a study on the changing practices of kinship in Northern India. The change in kinship arrangements, and particularly in intermarriage processes, is traced by analysing the reception of Hindi popular cinema. Films and their role and meaning in people´s lives in India was the object of my research. Films also provided me with a methodology for approaching my other subject-matters: family, marriage and love. Through my discussion of cultural change, the persistence of family as a core value and locus of identity, and the movie discourses depicting this dialogue, I have looked for a possibility of compromise and reconciliation in an Indian context. As the primary form of Indian public culture, cinema has the ability to take part in discourses about Indian identity and cultural change, and alleviate the conflicts that emerge within these discourses. Hindi popular films do this, I argue, by incorporating different familiar cultural narratives in a resourceful way, thus creating something new out of the old elements. The final word, however, is the one of the spectator. The “new” must come from within the culture. The Indian modernity must be imaginable and distinctively Indian. The social imagination is not a “Wild West” where new ideas enter the void and start living a life of their own. The way the young women in Dehra Dun interpreted family dramas and romantic movies highlights the importance of family and continuity in kinship arrangements. The institution of arranged marriage has changed its appearance and gained new alternative modes such as love cum arranged marriage. It nevertheless remains arranged by the parents. In my thesis I have offered a social description of a cultural reality in which movies act as a built-in part. Movies do not work as a distinct realm, but instead intertwine with the social realities of people as a part of a continuum. The social imagination is rooted in the everyday realities of people, as are the movies, in an ontological and categorical sense. According to my research, the links between imagination and social life were not so much what Arjun Appadurai would call global and deterritorialised, but instead local and conventional.

Molecular genetics of Usher syndrome -inherited deafness and blindness

Usher syndrome (USH) is an inherited blindness and deafness disorder with variable vestibular dysfunction. The syndrome is divided into three subtypes according to the progression and severity of clinical symptoms. The gene mutated in Usher syndrome type 3 (USH3), clarin 1 (CLRN1), was identified in Finland in 2001 and two mutations were identified in Finnish patients at that time. Prior to this thesis study, the two CLRN1 gene mutations were the only USH mutations identified in Finnish USH patients. To further clarify the Finnish USH mutation spectrum, all nine USH genes were studied. Seven mutations were identified: one was a previously known mutation in CLRN1, four were novel mutations in myosin VIIa (MYO7A) and two were a novel and a previously known mutation in usherin (USH2A). Another aim of this thesis research was to further study the structure and function of the CLRN1 gene, and to clarify the effects of mutations on protein function. The search for new splice variants resulted in the identification of eight novel splice variants in addition to the three splice variants that were already known prior to this study. Studies of the possible promoter regions for these splice variants showed the most active region included the 1000 bases upstream of the translation start site in the first exon of the main three exon splice variant. The 232 aa CLRN1 protein encoded by the main (three-exon) splice variant was transported to the plasma membrane when expressed in cultured cells. Western blot studies suggested that CLRN1 forms dimers and multimers. The CLRN1 mutant proteins studied were retained in the endoplasmic reticulum (ER) and some of the USH3 mutations caused CLRN1 to be unstable. During this study, two novel CLRN1 sequence alterations were identified and their pathogenicity was studied with cell culture protein expression. Previous studies with mice had shown that Clrn1 is expressed in mouse cochlear hair cells and spiral ganglion cells, but the expression profile in mouse retina remained unknown. The Clrn1 knockout mice display cochlear cell disruption/death, but do not have a retinal phenotype. The zebrafish, Danio rerio, clrn1 was found to be expressed in hair cells associated with hearing and balance. Clrn1 expression was also found in the inner nuclear layer (INL), photoreceptor layer and retinal pigment epithelium layer (RPE) of the zebrafish retina. When Clrn1 production was knocked down with injected morpholino oligonucleotides (MO) targeting Clrn1 translation or correct splicing, the zebrafish larvae showed symptoms similar to USH3 patients. These larvae had balance/hearing problems and reduced response to visual stimuli. The knowledge this thesis research has provided about the mutations in USH genes and the Finnish USH mutation spectrum are important in USH patient diagnostics. The extended information about the structure and function of CLRN1 is a step further in exploring USH3 pathogenesis caused by mutated CLRN1 as well as a step in finding a cure for the disease.

The Transcriptional Regulation of Retrotransposon BARE

The purpose of this research project was to understand the steps of the retrotransposon BARE (BArley REtrotransposon) life cycle, from regulation of transcription to Virus-Like Particle (VLP) formation and ultimate integration back into the genome. Our study concentrates mainly on BARE1 transcriptional regulation because transcription is the crucial first step in the retrotransposon life cycle. The BARE element is a Class I LTR (Long Terminal Repeat) retrotransposon belonging to the Copia superfamily and was originally isolated in our research group. The LTR retrotransposons are transcribed from promoters in the LTRs and encode proteins for packaging of their transcripts, the reverse transcription of the transcripts into cDNA, and integration of the cDNA back into the genome. BARE1 is translated as a single polyprotein and cleaved into the capsid protein (GAG), integrase (IN), and reverse transcriptase-RNaseH (RT-RH) by the integral aspartic proteinase (AP). The BARE retrotransposon family comprises more than 104 copies in the barley (Hordeum vulgare) genome. The element is bound by long terminal repeats (LTRs, 1829 bp) containing promoters required for replication, signals for RNA processing, and motifs necessary for the integration of the cDNA. Members of the BARE1 subfamily are transcribed, translated, and form virus-like particles. Several basic questions concerning transcription are explored in the thesis: BARE1 transcription control, promoter choice in different barley tissues, start and termination sites for BARE transcripts, and BARE1 transcript polyadenylation (I). Polyadenylation is an important step during mRNA maturation, and determines its stability and translatability among other characteristics. Our work has found a novel way used by BARE1 to make extra GAG protein, which is critical for VLP formation. The discovery that BARE1 uses one RNA population for protein synthesis and another RNA population for making cDNA has established the most important step of the BARE1 life cycle (III). The relationship between BARE1 and BARE2 has been investigated. Besides BARE, we have examined the retrotransposon Cassandra (II), which uses a very different transcriptional mechanism and a fully parasitic life cycle. In general, this work is focused on BARE1 promoter activity, transcriptional regulation including differential promoter usage and RNA pools, extra GAG protein production and VLP formation. The results of this study give new insights into transcription regulation of LTR retrotransposons.

Yhteisestä toiminnasta yhteiseen kieleen : keskustelunanalyyttinen tutkimus toisen kielen oppimisesta kielikylpypäiväkodin arkitilanteissa

This dissertation examines how Finnish-speaking children learn Swedish in an immersion kindergarten where the method of Canadian immersion is used. Within the framework of conversation analysis, this study explores how second language learning is situated in interaction and evidenced in the participants´ verbal and non-verbal behavior. The database consists of 40 hours of videotaped data collected in naturally occurring situations in a group of 15 four-year-old children during the first two years of their immersion. Due to the immersion method, all the children share the same L1, in this case Finnish, and the teachers understand Finnish. However, they speak only Swedish to the children in all situations and Swedish is learned in interaction without formal teaching. The aim of the study is to discover how the children´s second language competence gradually increases when they participate in interaction with the Swedish-speaking teachers. The study also sheds light on the methodological question of how second language learning can be analyzed with the method of conversation analysis. The focus is on showing how the second language is learned in interaction, especially on how learning is achieved collaboratively. In this study, the emerging second language competence is explored by investigating how the children show understanding of the teachers´ non-verbal and verbal actions during the first and the second semester of the immersion. The children´s use of Swedish is analyzed by investigating how they recycle lexical items and later even syntactic structures from the teachers´ Swedish turns. The results show that the teachers´ actions are largely understood by the children even at the beginning of the immersion. The analyzes of the children´s responsive turns reveal that they interpret the teachers´ turns on the basis of non-verbal cues at first. Especially at the beginning of the immersion, the participants orient to the progress of interaction and not to problems in understanding. Even in situations where the next actions show that the children do not understand what is said, they tend to display understanding rather than non-understanding. This behavior changes, however, when the children´s competence in their second language increases. At the second semester, the children both show understanding of the teachers´ verbal turns and also display their non-understanding by initiating repair when they do not understand. Understanding of the teachers´ verbal turns, including their syntactic structure, is manifested in the ways the children tie their turns to the teachers´ turns. Recycling, on the other hand, proves to be the way by which the children start to speak the second language. In this study, the children´s common L1 is evidenced to be an important resource in interaction. It allows the children to participate in their individual ways and to share their experiences both with each other and with the teachers. It also enables them to co-construct conversations that lead to collaborative learning. Moreover, the uninhibited use of L1 proves to be an important analytic tool that makes the immersion data especially fruitful for conversation analytic research on second language learning, since the children´s interpretations of the second language are in evidence even when they do not speak the second language.

Tietokone ikäihmisen arjessa

The aged people in the target group of my study belong to generation, which has experienced the shift from agricultural society via industrial society up to the society which has been described as information society. They have grown up concurrently with the technological development, but during the recent years the technological development has accelerated. One can say that the older the target study group has come the more information technological skills they need to possess to be equal actors in our society. However, especially in case of aged people the learning and maintaining of skills in information technology has mainly been left dependent on their personal motivation. The purpose of this report is to study the use of computers in the life of the aged people. The report studies the will and ability of the aged people to learn the skill of using computers, and the new possibilities which this brings into their lives. The study questions are the following: 1) Why the aged people start to use computers? 2) How the aged people benefit information technology in their own life? 3) How computers have extended the environment of the aged people? 4) What kind of problems the aged people have experienced in use of computers? The research material consists of group interviews and individual interviews (total of 23 people). The interview material has been collected among the participants on information technology courses of the Senior University of Helsinki University during years 2004-2005. The research method used is theme interviewing. In addition, the material of opinions about information technology of people born in decades of 1920 and 1930, gathered as part of the Ikihyvä Päijät-Häme 2002 -research has been used. On basis of this research one can say that the aged people do have motivation to study the use of computers, although many interviewees commented that they also have met problems in use of computers. The motivation has grown also because the fear that without the skills to use computers they could drift into outsiders of the society, whereas instead as skilled computer users they felt to be equal citizens compared with the younger age groups, and that they can maintain their independence and autonomy. Especially, the independent use of banking routines over the Internet and use of emails seem to give them a position as modern actors. Many interview statements also underline that computers will bring both joy and benefit to the users. Studying the use of computers is a new and interesting hobby, which can fill the hole left in the life after leaving the working life. Using skills of text processing and processing of pictures one can, for example, record the traditional knowledge of the family and ancestry to the younger generations, and write articles or even books on the professional area of ones own. Single people emphasize that computers can even act as companionship substitutes. One can use Internet for virtual traveling, which provides a new dimension in use of computers. Internet can also be used to maintain family relationships, especially between grandparents and remote grandchildren. Typical problems in use of computers appeared to be that reaching the right professional helpdesk advisers of the service providers is difficult and requires lots of time and patience. However, the interviewees were not willing to give up their computers, because they had already used to these. Keywords: digital divide, aging, Internet, usability, motivation, information technology, information society.

Osallistuminen ja läpinäkyvyys kuntatasolla : tapaustutkimus Nicaraguasta

In this Master's thesis I go through the principals of the good governance. I apply these principals to the Nicaraguan context and especially in two rural municipalities in Chontales department. I clarify the development of the space of participation in Nicaraguan municipal level. I start my examination from the period when Somoza dictatorship ended and first open elections were held, and I end it to the municipal eleccions held in November 2008. These elections were robbed in 33 municipalities and because of this there started a crisis in Nicaragua and among the actors of development cooperation. As a methods of research I use two types of interview in the thesis, the interviews for the citizens and interviews for the experts. These interviews answer to my questions of the methods of participation. I also review the level of the trust of a citizen to an authority by asking if s/he voted in the municipal eleccions in November 2008. Furthermore, I define the work of municipal government in the point of view of the citizen. I also find out if a citizen wants to take more part in the decision making in her/his municipal. I have classified the types of citizens by the interviews I made. Due to this classification I explain how many people actually have opportunity to participate the dialogue of the municipal decision making and how many can follow the activity of the municipal governance. The result is that after the elections in November 2008 only one typed group can freely take part in the dialogue. This does not apply the principals of good governance, especially in subterms of participation and transparency. The incidents after the municipal elections have affected strongly on the co-operation of Finland and Nicaragua. Because of the fault of the elections Finland like the other co-operative countries brought down the directly paid budget support. This has caused a great economical crisis in Nicaragua which the covering will take a long time. The Master's thesis is a case study of two rural municipalities called Santo Tómas and Villa Sandino. Santo Tómas has a sandinista municipal government which is not legitimate. In Villa Sandino the government is liberal and legitimate.

Koti keskellä kaupunkia : Keskusta lapsiperheen asuinalueena, esimerkkeinä Tukholma ja Helsinki

Families with children have traditionally moved to suburbs. In the last 20 years a modest counter process has however been recognized. Families with an urban lifestyle stay in the city centres. This study looks at the phenomenon through two cases, Stockholm and Helsinki. In the first case it has already been observed that the city centre has grown in popularity among families with children. Therefore it serves as a basis for the study and as well as a point of comparison. Stockholm’s city centre is expanding as new neighbourhoods have been built and are being planned. In the city centre of Helsinki the building of two large neighbourhoods for 30 000 inhabitants will start in a few years. The first aim of the study is to look closer at what has really happened in the city centre of Stockholm, why families choose to live there with their children and how the City of Stockholm has reacted to the change. The main sources of information are secondary sources, statistics and interviews with planners, politicians and experts in the field. The main object is to look at the situation in the city centre of Helsinki. Can a preference for urban residential environments be observed in Helsinki? What are the reasons for a family to choose the city centre as a living place? How does the everyday life of a family in the city centre appear? How are these families taken into account in the planning of the city? The main sources of information here are statistics, interviews with dwellers in the neighbourhood Kruununhaka and interviews with planners. In Stockholm the birth rate has grown constantly during the 2000s and is highest in the city centre. Some of the families still move elsewhere, but many of them do not. One of the most important reasons for living in the city centre is short working distances which give working parents more time with their children. Another reason is a preference of an urban, active lifestyle. Families prefer to live close to everything, childcare, schools, shops and entertainments. The popularity of the city centre among families with children has taken politicians and planners by surprise. Helsinki has not experienced a baby boom like Stockholm. However the negative changes in the birth rate have been more modest in the central areas than in the suburbs. Statistics show, that many families move away from the city centre as the children grow. Families who stay in the city centre especially appreciate closeness to public and private services and good public transportation which means that they are not dependent on using the car. Further they find that the city centre has a tolerant climate and is a safe and beautiful place to live in. The families enjoy the social life of the neighbourhood and feel that it makes a good climate to raise children in. However they are concerned with traffic safety and the lack of stimulus in the playgrounds of the neighbourhood parks. Two large neighbourhoods with homes for about 30 000 inhabitants are now planned in the former Port Districts in the city centre of Helsinki. The other one, Jätkäsaari has been planned to become an attractive alternative for families with children. Traffic safety has been one of the main objects for the planning. The other, Kalasatama, has been planned to attract all groups in society.
