Morality and Gender in Jeff Lindsay's Dexter Novels

Tutkimuksessa analysoin neljää Jeff Lindsayn Dexter -dekkaria kahdesta eri näkökulmasta. Ensimmäinen osa keskittyy päähenkilön sosiopaattisen persoonan aiheuttamiin moraalisiin ristiriitoihin, sillä hän on sekä sarjamurhaaja että työskentelee poliisin laboratoriossa silti noudattaen erittäin tiukkaa moraalista ohjenuoraa, joka määrittää kenet hän saa tappaa. Tutkimuksen toinen osa tarkastelee kirjojen naishahmoja ja heidän ongelmiaan. Käsittelen lyhyesti myös kirjasarjan ja niiden pohjalta tehdyn televisiosarjan eroja. Metodeina käytän lähiluentaa, eettistä analyysiä sekä rikoskirjallisuuden alalajien vertailua. Vaikkei rikoskirjallisuudessa olekaan yleistä, että poliisi tai tutkija olisi siviilissä rikollinen, on Dexter hyvin tyypillinen fiktiivinen sosiopaatti ja sarjamurhaaja. Lindsayn kirjojen juonet ja Dexter päähenkilönä noudattavat paikoin lähes kirjaimellisesti Thomas Harrisin Hannibal Lecterille luomaa kaavaa. Kirjojen moraaliset ristiriidat taas aiheutuvat sekä Dexterin roolista lainvartijana ja -rikkojana että hänen noudattamastaan tiukasta moraalisesta ohjenuorasta, joka määrittää kenet saa tappaa. Sosiopaattina hänen pitäisi olla kaikkien yhteiskunnan asettamien lakien ja rajoitusten tavoittamattomissa, mutta silti hänen päätöksentekonsa perustuu täysin kasvatti-isänsä laatimiin ohjeisiin. Tämä on yksi Dexterin hahmon suurimmista ristiriitaisuuksista, joka vahvistaa Heta Pyrhösen esittämän ajatuksen siitä, ettei rikoskirjallisuus tule toimeen ilman vahvaa moraalista selkärankaa. Dexterin tiukka moraalinen ohjenuora ja lukijoiden samaistuminen päähenkilöön ovat kuitenkin todennäköisin syy hänen selviytymiseensä kirjasta toiseen, ja sarjan myötä Dexter muuttuukin inhimillisemmäksi kuin alussa. Toisaalta naishahmojen ongelmien havaitseminen on vaikeaa, sillä ensivaikutelman perusteella voisi kuvitella, että Lindsayn kuvaama yhteiskunta on jo ratkaissut kaikki tasa-arvo-ongelmansa. Sukupuolten ja kansanryhmien välisestä tasa-arvosta ei kirjoissa keskustella, mutta merkittäviä naishahmoja on silti huomattavan vähän, eikä heistäkään ole rakennettu yhtä johdonmukaisia ja mielenkiintoisia kuin päähenkilöstä esimerkiksi. He jäävät pitkälti Dexterin varjoon. Edes Dexterin sisko Deborah ei pysty säilyttämään osaansa kirjojen naispäähenkilönä, sillä hänen ammattitaitoaan poliisina ja olemustaan naisena kuvataan jatkuvan ristiriitaisesti. Kaksi seuraavaksi tärkeintä naishahmoa ovat Dexterin tyttöystävä Rita, joka toimii äitiyden ruumiillistumana, sekä hänen tyttärensä Astor, joka on veljensä ohella samanlainen sosiopaatti kuin Dexter. Naissarjamurhaajien puute ja naishahmojen epäjohdonmukainen kuvaus ovat yksi Lindsayn kirjojen suurimmista ongelmista. Analyysin keskeisimmät johtopäätökset paljastavat, miten omaperäisyydestään huolimatta Dexter muistuttaa huomattavasti muita tunnettuja fiktiivisiä sarjamurhaajia, ja miten Lindsay pohjaa tekstinsä amerikkalaiseen arvomaailmaan ja rikoskirjallisuuden alalajien konventioihin. Vaikka suurin osa lukijoista pystyykin käsittelemään Dexterin tekojen moraalisia ristiriitoja, voi sarjamurhaajan ihannointi aiheuttaa toisille ongelmia. Toisaalta luomalla monipuolisia ja johdonmukaisia naishahmoja, jotka pystyisivät säilyttämään itsenäisyytensä kaikissa tilanteissa, Lindsayn kirjat olisivat sekä ajankohtaisempia että omaperäisempiä kuin nyt.

Ohjauskeinot ilmastoa vähemmän kuormittaviin elintarvikevalintoihin

Elintarvikkeiden tuotannon ja kulutuksen ilmastovaikutukset ovat huomattavat, noin neljännes kulutuksen ilmastovaikutuksista liittyy elintarvikkeisiin ja syömiseen. Elintarvikkeiden tuotannon ja kulutuksen ilmastomyötäisyys on yhä enemmän esillä eri maiden elintarvikkeisiin liittyvissä strategioissa, ohjelmissa, ohjeistuksissa, suosituksissa ja yhteisessä maatalouspolitiikassa. Tämän tutkielman tavoitteena oli tutkia, millaisia ohjauskeinoja voidaan käyttää ohjaamaan elintarvikkeiden kulutusta ja tuotantoa ilmastomyötäisemmäksi, mitkä keinot ovat käyttökelpoisimpia, millaisia haasteita ohjauskeinojen käyttöön liittyy ja millaisena eri elintarvikesektoriin vaikuttavien tahojen roolia ohjauksessa pidetään. Tutkimuksessa selvitettiin lisäksi eri ohjauskeinojen vahvuuksia, mahdollisuuksia, heikkouksia ja uhkia. Tutkimus keskittyi elintarvikkeiden kulutukseen, mutta ohessa selvitettiin myös tuotantoon liittyviä ohjauskeinoja. Kvalitatiivinen tutkimus suoritettiin teemahaastatteluina. Haastatteluja tehtiin yhteensä 24 kappaletta. Haastateltavat olivat elintarviketeollisuudesta, alkutuotannosta, kaupan alalta, politiikasta, valtionhallinnosta ja asiantuntijayrityksestä, tutkimuslaitoksista sekä kuluttaja- ja kansalaisjärjestöistä. Elintarvikkeiden kulutuksen ja tuotannon ohjaaminen ilmastonäkökulmasta on haasteellista. Ilmastomyötäiseen ruokavalioon siirtymistä pidettiin tärkeänä. Siksi voidaan katsoa, että ohjausta tarvitaan ja ainakin alustava tahtotila ohjaavien keinojen käyttöönottoon on jo olemassa. Toisaalta oltiin kuitenkin sitä mieltä, että ohjausta ei tulisi perustaa vain ilmastonäkökulmaan. Informaatio-ohjaus nähtiin kuluttajien ohjaamisessa keskeisenä keinona. Suurin osa haastateltavista käyttäisi ohjauskeinona informaatio-ohjausta, vaikka sen vaikuttavuudesta oltiin montaa mieltä. Elintarvikkeiden kuluttajahintoihin vaikuttamisen katsottiin ohjaavan kuluttajien valintoja. Hintaan vaikuttamisen nähtiin tapahtuvan lähinnä erilaisten veroratkaisujen kautta. Maataloustukiin vaikuttamista pidettiin myös ohjaavana keinona. Koulutusta, joukkoruokailua ja ilmastonäkökulman sisältäviä ravitsemussuosituksia pidettiin potentiaalisina keinoina vaikuttaa ruokailutottumuksiin. Tehdyn tutkimuksen perusteella voidaan sanoa, että tutkimustiedon lisääminen elintarvikkeiden ilmastokuormasta, ohjauskeinojen vaikutuksista ja vaikuttavuudesta on edellytys tehokkaalle elintarvikkeiden kulutuksen ja tuotannon ilmastonäkökulman huomioivalle ohjaukselle.

Suomi toisena kielenä vai lukivaikeus? : Luokanopettajien käsityksiä oppilaiden kielellisistä vaikeuksista

Goals. Immigrant pupils are over-represented in special education. Linguistic difficulties are the most pivotal reasons for social exclusion of immigrant pupils during their school career. Addedly reading, writing, and language development disorders are the most common reasons for both part-time and extensive special education. I studied class teachers' perceptions of the typical linguistic difficulties of pupils who speak Finnish as their second language and of those who have dyslexia, because I suspect that telling the difference between linguistic competency in progress and the symptoms of dyslexia isn't easy. I look for overlappings in the perceptions of linguistic difficulties, their causes and their support measures, which would reveal the challenges in recognizing linguistic difficulties, which in turn might partly explain why immigrant pupils are over-represented in special education. Methods. This study was carried out as structured individual interviews with nine class teachers from the Helsinki Metropolitan Area. To increase reliability, complementary information was gathered about the same phenomenon with a questionnaire that each interviewee filled out at the end of the interview. It was required that the interviewees have experience of teaching both dyslexic pupils and pupils who speak Finnish as a second language. The material analysis was mainly deductive, but the material that wasn't in line with the theoretical frame of reference was analyzed inductively. Results and conclusions. There were overlappings in the class teachers' perceptions of the linguistic difficulties, support measures fitting them and, based on the questionnaire results, also of the causes of these difficulties. Additionally all the interviewees said it to be difficult to recognize dyslexia in a pupil who speaks Finnish as a second language. I came to the conclusion that distinguishing different linguistic difficulties from one another is a challenge to which class teachers don't always feel competent to rise, which is why they consider the assistance of special teachers and other professionals beneficial.

Leisure-time physical activity, health related functioning and retirement : a prospective cohort study among middle-aged employees

Physical inactivity has become a major threat to public health worldwide. The Finnish health and welfare policies emphasize that the working population should maintain good health and functioning until their normal retirement age and remain in good health and independence later in life. Health behaviours like physical activity potentially play an important role in reaching this target as physical activity contributes to better physical fitness and to reduced risk of major chronic diseases. The aim of this study was to examine first whether the volume and intensity of leisure-time physical activity impacts on subsequent physical health functioning, sickness absence and disability retirement. The second aim was to examine changes in leisure-time physical activity of moderate and vigorous intensity after transition to retirement. This study is part of the ongoing Helsinki Health Study. The baseline data were collected by questionnaires in 2000 - 02 among the employees of the City of Helsinki aged 40 to 60. The follow-up survey data were collected in 2007. Data on sickness absence were obtained from the employer s (City of Helsinki) sickness absence registers and pension data were obtained from the Finnish Centre for Pensions. Leisure-time physical activity was measured in four grades of intensity and classified according to physical activity recommendations considering both the volume and intensity of physical activity. Statistical techniques including analysis of covariance, logistic regression, Cox proportional hazards models and Poisson regression were used. Employees who were vigorously active during leisure time especially had better physical health functioning than those physically inactive. High physical activity in particular contributed to the maintenance of good physical health functioning. High physical activity also reduced the risk of subsequent sickness absences as well as the risk of all-cause disability retirement and retirement due to musculoskeletal and mental causes. Among those transferred to old-age retirement moderate-intensity leisure-time physical activity increased on average by more than half an hour per week and in addition the occurrence of physical inactivity reduced. Such changes were not observed among those remained employed and those transferred to disability retirement. This prospective cohort study provided novel results on the effects of leisure-time physical activity on health related functioning and changes in leisure-time physical activity after retirement. Although the benefits of moderate-intensity physical activity for health are well known these results suggest the importance of vigorous physical activity for subsequent health related functioning. Thus vigorous physical activity to enhance fitness should be given more emphasis from a public health perspective. In addition, physical activity should be encouraged among those who are about to retire.

Bovine mastitis caused by coagulase-negative staphylococci : host response and bacterial factors

Coagulase-negative staphylococci (CNS) are the most common bacteria isolated in bovine subclinical mastitis in many countries, and also a frequent cause of clinical mastitis. The most common species isolated are Staphylococcus (S) chromogenes, S. simulans, S. epidermidis, and S. xylosus. One half of the intramammary infections (IMI) caused by CNS persist in the udder. The pathogenesis of IMI caused by CNS is poorly understood. This dissertation focuses on host response in experimental intramammary infection induced by S. chromogenes, S. epidermidis and S. simulans. Model for a mild experimental CNS infection was developed with S. chromogenes (study I). All cows were infected and most developed subclinical mastitis. In study II the innate immune response to S. epidermidis and S. simulans IMI was compared in eight cows using a crossover design. A larger dose of bacteria was used to induce clinical mastitis. All cows became infected and showed mild to moderate clinical signs of mastitis. S. simulans caused a slightly stronger innate immune response than S. epidermidis, with significantly higher concentrations of the interleukins IL-1beta and IL-8 in the milk. The spontaneous elimination rate of the 16 IMIs was 31%, with no difference between species. No significant differences were recorded between infections eliminated spontaneously or remaining persistent, although the response was stronger in IMIs eliminated spontaneously, except the concentration of TNF-α, which remained elevated in persistent infections. Lactoferrin (Lf) is a component of the humoral defence of the host and is present at low concentrations in the milk. The concentration of Lf in milk is high during the dry period, in colostrum, and in mastitic milk. The effect of an inherent, high concentration of Lf in the milk on experimental IMI induced with S. chromogenes was studied in transgenic cows that expressed recombinant human Lf in their milk. Human Lf did not prevent S. chromogenes IMI, but the host response was milder in transgenic cows than in normal cows, and the former eliminated infection faster. Biofilm production has been suggested to promote persistence of IMI. Phenotypic biofilm formation and slime producing ability of CNS isolates from bovine mastitis was investigated in vitro. One-third of mastitis isolates produced biofilm. Slime production was less frequent for isolates of the most common mastitis causing species S. chromogenes and S. simulans compared with S. epidermidis. No association was found between the phenotypic ability to form biofilm and the persistence of IMI or severity of mastitis. Slime production was associated with persistent infections, but only 8% of isolates produced slime.

Kirjallisuusosa: Alzheimerin taudin rottamallien vastaavuus tautiin ihmisessä ja mallien käyttökelpoisuus

Kirjallisuusosa: Alzheimerin taudin hoitoon olisi tarvetta uusille taudinkulkuun vaikuttaville lääkeaineille. Niiden kehittämiseksi tarvitaan eläinmalleja, joissa esiintyy taudin patofysiologisia piirteitä. Rottamalleista vanhemmat skopolamiini- tai MK-801-häirintä sekä ikääntyneiden rottien käyttö eivät kovin hyvin vastaa taudin patofysiologiaa, vaikka niissä eläimen muisti käyttäytymiskokeissa onkin heikentynyt. Uudemmat transgeeniset rottamallit ja mallit, joissa annetaan Aβ:a aivoihin, ilmentävät huomattavasti paremmin Alzheimerin taudin kaltaista tilaa aivoissa ainakin Aβ:n osalta. Taupatofysiologiaa ei silti kummassakaan näistä malleista juuri esiinny. Toisaalta Aβ:lla näyttäisi olevan huomattavasti tau:ta suurempi rooli taudissa, joten sen ilmeneminen mallissa onkin keskeisempi tekijä. Nämä mallit ilmentävät melko suurelti osin yhtä hyvin Alzheimerin taudin patofysiologiaa. Aβ:n antaminen on hieman yksinkertaisempi suorittaa käytännössä, sillä siinä ei tarvitse luoda transgeenista kantaa. Toisaalta transgeenisessa mallissa Aβ-patofysiologia syntyy enemmän Alzheimerin taudin kaltaisesti solujen sisällä eikä valmiita aggregoituvia Aβ-peptidejä anneta ulkopuolelta aivoihin. Molemmat mallit ovat kuitenkin käyttökelpoisia, ja soveltuvat erityisesti Aβ:an vaikuttavien lääkeaineiden kehittämiseen. Kokeellinen osa: Kokeen tarkoituksena oli validoida kohotettu ristikko-sokkelo (elevated plus-maze, EPM) hiirillä kognitiomallina. Kokeessa käytettiin kahden koekerran (trial, T) menetelmää, jossa koekertojen pituus oli viisi minuuttia. Näin saatiin useita oppimista kuvaavia parametreja. Hiirille yritettiin saada muistihäiriö aikaviiveen avulla (koekertojen väli 1-18 vrk) tai antamalla muskariinireseptoriantagonistia skopolamiinia (0,1-0,8 mg/kg i.p.) 30 minuuttia ennen T1:tä. Nämä kokeet suoritettiin sekä C57BL/6J- että ICR:(CD-1)-hiirillä. Aikaviivekokeissa ainut ryhmä, jolla oli viitettä unohtamisesta, oli ICR:(CD-1)-hiirien 18 vrk:n ryhmä. Tämän perusteella tutkittiin vielä 21 vuorokauden aikaväli, mutta selvää muistihäiriötä ei esiintynyt. Skopolamiini ei häirinnyt muistia ICR:(CD-1)-hiirillä, mutta C57BL/6J-hiirillä 0,2 mg/kg:n annoksesta ylöspäin merkitsevä muistihäiriö esiintyi. Näin ollen jatkokokeissa käytettäväksi valittiin skopolamiinin annos 0,2 mg/kg C57BL/6J-hiirillä, ja siinä tutkittiin donepetsiilin (0,3, 0,8 ja 1,5 mg/kg s.c), memantiinin (5,0 ja 10,0 mg/kg s.c) ja kokeellisen 5-HT6-antagonistin SB742457:n (1,5 ja 6,0 mg/kg s.c) muistia parantavia vaikutuksia. Tutkittavat lääkeaineet annettiin 40 minuuttia ennen T1:tä ja skopolamiini 30 minuuttia ennen. Memantiinilla (5,0 mg/kg) oli selkeä skopolamiinin heikentämää kognitiota parantava vaikutus ja donepetsiilillakin (1,5 mg/kg) suuntaus tähän. Tulosten perusteella malli näyttäisi soveltuvan muisti- ja oppimisvaikutusten tutkimiseen käytettäväksi malliksi.

Physical properties of a boreal clay soil under differently managed perennial vegetation

The physical properties of surface soil horizons, essentially pore size, shape, continuity and affinity for water, regulate water entry into the soil. These properties are prone to changes caused by natural forces and human activity. The hydraulic properties of the surface soil greatly impact the generation of surface runoff and accompanied erosion, the major concern of agricultural water protection. The general target of this thesis was to improve our understanding of the structural and hydraulic properties of boreal clay soils. Physical properties of a clayey surface soil (0 - 10 cm, clay content 51%), with a micaceous/illitic mineralogy subjected to three different management practices of perennial vegetation, were studied. The study sites were vegetated buffer zones located side by side in SW Finland: 1) natural vegetation with no management, 2) harvested once a year, and 3) grazed by cattle. The soil structure, hydraulic properties, shrinkage properties and soil water repellency were determined at all sites. Two distinct flow domains were evident. The surface soil was characterized by subangular blocky, angular blocky and platy aggregates. Hence, large, partially accommodated, irregular elongated pores dominated the macropore domain at all sites. The intra-aggregate pore system was mostly comprised of pores smaller than 30 μm, which are responsible for water storage. Macropores at the grazed site, compacted by hoof pressure, were horizontally oriented and pore connectivity was poorest, which decreased water and air flux compared with other sites. Drying of the soil greatly altered its structure. The decrease in soil volume between wet and dry soil was 7 - 10%, most of which occurred in the moisture range of field conditions. Structural changes, including irreversible collapse of interaggregate pores, began at matric potentials around -6 kPa indicating, instability of soil structure against increasing hydraulic stress. Water saturation and several freezethaw cycles between autumn and spring likely weakened the soil structure. Soil water repellency was observed at all sites at the time of sampling and when soil was dryer than about 40 vol.%. (matric potential < -6 kPa). Therefore, water repellency contributes to water flow over a wide moisture range. Water repellency was also observed in soils with low organic carbon content (< 2%), which suggests that this phenomenon is common in agricultural soils of Finland due to their relatively high organic carbon content. Aggregate-related pedofeatures of dense infillings described as clay intrusions were found at all sites. The formation of these intrusions was attributed to clay dispersion and/or translocation during spring thaw and drying of the suspension in situ. These processes generate very new aggregates whose physical properties are most probably different from those of the bulk soil aggregates. Formation of the clay infillings suggested that prolonged wetness in autumn and spring impairs soil structure due to clay dispersion, while on the other hand it contributes to the pedogenesis of the soil. The results emphasize the dynamic nature of the physical properties of clay soils, essentially driven by their moisture state. In a dry soil, fast preferential flow is favoured by abundant macropores including shrinkage cracks and is further enhanced by water repellency. Increase in soil moisture reduces water repellency, and swelling of accommodated pores lowers the saturated hydraulic conductivity. Moisture- and temperature-related processes significantly alter soil structure over a time span of 1 yr. Thus, the pore characteristics as well as the hydraulic properties of soil are time-dependent.

Kansalaisuus työyhteisön arjessa : Maahanmuuttajien kertomuksia työelämästä

Citizenship in the everyday of a work community. Immigrants narratives of working life. Through globalisation and the mobility of workforce, citizenship has gained new forms, and the mere legal definition of citizenship no longer gives a comprehensive view of the citizenship of an individual. Also the social, cultural and financial dimensions of it are related to the concept of citizenship. In Finland, full citizenship is promoted, according to the Integration Act and social security system, by the requirement that immigrants should mainly get their livelihood through work. In my study I approach citizenship on four levels: the global, national, work community and private levels. In the study, the global has constituted the largest possible context, which refers to the local affects of global processes. The local and the global come together in the research in that globalisation is realised on the local level, i.e. in small communities such as work communities. The objective of the study is to examine how the citizenship of immigrants who live and work in Finland is constructed in the everyday life of a work community. The most central concept of the study is cultural script, which is based on prevailing forms of knowing, and which are constructed in different ways in different times and cultures. Conflicts of scripts in the working life and difficulties in understanding and applying them are in the centre of the study. In the study, the working life experiences of immigrants are approached through narrative research. The research material consists of the working life narratives of nine immigrants who live and work in Finland permanently. Each interviewee has been interviewed 2 4 times so the research material consists of 26 interviews. The material has been analysed from the points of view of perception, feeling and action. Deborah Tannen s and William Labov s as well as Matti Hyvärinen s method of expectancy analysis to locate cultural scripts has been utilised to organise the research material. In addition, David Herman s concepts of participatory roles and event types formed in narratives have been used in the analysis of the material. The basis in the analysis is that the world, events and experiences do not define the available processes; they are always culturally and individually anchored choices of the speaker and narrator. The most important results of the study are related to the gap between globalisation and everyday life. The discussion about the future need for workforce due to the changing population structure as well as about the benefits for national economy brought by internationalisation has continued in Finland for years. However, the working life narratives of the immigrants interviewed for the study show that an average citizen and member of a work community does not immediately encounter the macro level benefits in, for example, the mobility of workforce. In most of the working life narratives there was a point in speaking and saying, in which the immigrant worker either dares to speak or falls silent. Sometimes the courage to speak was related to language skills but more to the courage to be seen and to be part of a Finnish work community. Other workers that either speak their colleague with an immigrant background into a part of their work community or marginalise the colleague with their silence have an important role in a Finnish work community. In several working life narratives, the script of the Finnish working life and work community, the way to work, was opened to the immigrant and the so-called script exchange did not take place. The study shows that working life experiences and inclusion and exclusion built on the working life have an important role in the construction of active citizenship. The detailed analysis of the working life experience narratives gives new, relevant research data about citizenship as inclusion.

Hostility: A prospective study of the genetic and environmental background and associations with cardiovascular risk

Hostility is a multidimensional construct having wide effects on society. In its different forms, hostility is related to a large array of social and health problems, such as criminality, substance abuse, depression, and cardiovascular risks. Identifying and tackling early-life factors that contribute to hostility may have public health significance. Although the variance in hostility is estimated to be 18-50 percent heritable, there are significant gaps in knowledge regarding the molecular genetics of hostility. It is known that a cold and unsupportive home atmosphere in childhood predicts a child s later hostility. However, the long-term effects of care-giving quality on hostility in adulthood and the role of genes in this association are unclear. The present dissertation is part of the ongoing population-based prospective Young Finns study, which commenced in 1980 with 3596 3-18-year-old boys and girls who were followed for 27 years. The specific aims of the dissertation were first to study the antecedents of hostility by looking at 1) the genetic background, 2) the early environmental predictors, and 3) the gene environment interplay behind hostility. As a second aim, the thesis endeavored to examine 4) the association between hostility and cardiovascular risks, and 5) the moderating effect of demographic factors, such as gender and socioeconomic status, on this association. The study found potential gene polymorphisms from chromosomes 7, 14, 17, and 22 suggestively associated with hostility. Of early environmental influences, breastfeeding and early care-giving were found to predict hostility in adulthood. In addition, a serotonin receptor 2A polymorphism rs6313 moderated the effect of early care-giving on later hostile attitudes. Furthermore, hostility was shown to predict cardiovascular risks, such as metabolic syndrome and inflammation. Finally, parental socioeconomic status was found to moderate the association between anger and early atherosclerosis. The new genetic and early environmental antecedents of hostility identified in this research may help in understanding the development of hostility and its health risks, and in planning appropriate prevention. The significance of early influences on this development is stressed. Although the markers studied are individual- and family-related factors, these may be influenced at the societal level by giving accurate information to all individuals concerned and by improving the societal circumstances.

Cox-2, tenascin, CRP, and ingraft chimerism in a model of post-transplant obliterative bronchiolitis

Chronic rejection in the form of obliterative bronchiolitis (OB) is the major cause of death 5 years after lung transplantation. The exact mechanism of OB remains unclear. This study focused on the role of cyclo-oxygenase (COX) -2, tenascin, and C-reactive protein (CRP) expression, and the occurrence of ingraft chimerism (= cells from two genetically distinct individuals in a same individual) in post-transplant OB development. In our porcine model, OB developed invariably in allografts, while autografts stayed patent. The histological changes were similar to those seen in human OB. In order to delay or prevent obliteration, animals were medicated according to certain protocol. In the beginning of the bronchial allograft reaction, COX-2 induction occurred in airway epithelial cells prior to luminal obliteration. COX-2 expression in macrophages and fibroblasts paralleled the onset of inflammation and fibroblast proliferation. This study demonstrated for the first time, that COX-2 expression is associated with the early stage of post- transplant obliterative airway disease. Tenascin expression in the respiratory epithelium appeared to be predictive of histologic features observed in human OB, and influx of immune cells. Expression in the bronchial wall and in the early obliterative lesions coincided with the onset of onset of fibroblast and inflammatory cell proliferation in the early stage of OB and was predictive of further influx of inflammatory and immune cells. CRP expression in the bronchial wall coincided with the remodelling process. High grade of bronchial wall CRP staining intensity predicted inflammation, accelerated fibroproliferation, and luminal obliteration, which are all features of OB. In the early obliterative plaque, majority of cells expressed CRP, but in mature, collagen-rich plaque, expression declined. Local CRP expression might be a response to inflammation and it might promote the development of OB. Early appearance of chimeric (= recipient-derived) cells in the graft airway epithelium predicted epithelial cell injury and obliteration of the bronchial lumen, which both are features of OB. Chimeric cells appeared in the airway epithelium after repair following transplantation-induced ischemic injury. Ingraft chimerism might be a mechanism to repair alloimmune-mediated tissue injury and to protect allografts from rejection after transplantation. The results of this study indicate, that COX-2, tenascin, CRP, and ingraft chimerism have a role in OB development. These findings increase the understanding of the mechanisms of OB, which may be beneficial in further development of diagnostic options.

“YK:n ihmisoikeudet vankiloihin!” Marraskuun liikkeen suomalaisen kontrollipolitiikan kritiikki 1967—1972

Tutkimukseni aihe on Marraskuun liike, vuosina 1967-1972 toiminut suomalainen kontrollipoliittinen yhdistys. Marraskuun liike kuului 1960-luvun protestisykliin ja oli yksi rauhanliike Sadankomitean mallin mukaan perustetuista ns. yhden asian liikkeistä. Marraskuun liike ilmoitti ajavansa inhimillisempää ja järkiperäisempää kontrollipolitiikkaa. Se puolusti kontrollipolitiikan kohteiksi joutuneiden ihmisten eli vankien, asunnottomien alkoholistien, koulukotinuorten ja muiden kontrollitoimenpiteiden kohteeksi joutuneiden ja poikkeaviksi kutsumiensa ihmisten oikeuksia. Tutkimuskysymykseni koskivat Marraskuun liikkeen vaatimuksia, toimintaa ja ideologiaa. Näkökulmia tutkimuskohteeseen olivat tieteellisten teorioiden ja tiedon, ihmisoikeuksien ja vallankäytön merkitys liikkeen toiminnassa ja ideologiassa. Viitekehyksenä käytin liiketutkimusta ja aatehistoriallista tutkimusta. Lähdemateriaalina käytin Kansan arkistossa sijaitsevia Marraskuun liikkeen papereita, aikalaiskirjallisuutta ja lehtiartikkeleita. Lisäksi haastattelin seitsemää liikkeen entistä aktivistia. Marraskuun liikkeen lähtökohdat olivat vahvasti kytköksissä 1960-luvun yhteiskuntatieteelliseen tutkimukseen, erityisesti poikkeavan käyttäytymisen sosiologiaan. Siinä tutkijan katse kääntyi poikkeavasta yksilöstä kontrolloivaan järjestelmään. Marraskuun liikkeelle tärkeitä vaikutteita tuli sosiologi Kettil Bruunilta ja hänen johtamansa Alkoholipoliittisen tutkimuslaitoksen piirissä tehdyistä tutkimuksista, joista osa oli liikkeen jäsenten itsensä tekemiä. Pohjoismaisen kesäakatemian kautta saatiin vaikutteita norjalaisilta kriminologeilta. Erving Goffmanin laitoskritiikki tarjosi lähtökohdan suomalaisten laitosten kritisoitiin. Marraskuun liike järjesti teematempauksia, kuten asunnottomien alkoholistien juhlan, vankilaviikon ja koulukotiviikon. Se kritisoi hallinnollisia vapaudenriistoja eli ”pakkoauttamista” sekä hoitoideologiaa jonka se käänsi päälaelleen: yhteiskunta tarvitsi hoitoa, ei poikkeava yksilö. Liike vaikutti vahvasti julkisuuden kautta ja sillä oli hyvät yhteydet lehdistöön. Marraskuun liike kritisoi suomalaisia laitosoloja, ja halusi korvata suuren osan laitoshoidosta, varsinkin pakkoon perustuvan, avohoidolla ja ennaltaehkäisevillä toimenpiteillä. Hyvätekeväisyys haluttiin korvata ihmisoikeuksilla, ja poikkeavat ihmiset saada järjestäytymään. Konkreettisten vaatimusten taustalla vaikutti kriittinen suhtautuminen kontrollipolitiikan vallankäyttöön, jonka katsottiin ulottuvan laajalle ja heijastavan suomalaista luokkayhteiskuntaa. Aktiivisen ensimmäisen toiminnan vuoden 1968 jälkeen osa jäsenistä vaati liikkeen asettumista vallankumouksen kannalle. He pitivät kiinni kontrollipolitiikan sortavasta luonteesta ja asettivat Marraskuun liikkeen ideologian marxilaiseen kehykseen. Kiistoilla ”vallankumouksellisen” ja ”reformistisen linjan välillä oli toimintaa lamauttava vaikutus, mutta sitä kuitenkin jatkettiin yhdessä.

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.

Poststroke survival and ischemic stroke recurrence : the cerebral small-vessel disease perspective

The aim of the present study was to investigate the influence of different manifestations of cerebral SVD on poststroke survival and ischemic stroke recurrence in long-term follow-up. The core imaging features of small-vessel disease (SVD) are confluent and extensive white matter changes (WMC) and lacunar infarcts. These are associated with minor motor deficits but a major negative influence on cognition, mood, and functioning in daily life, resulting from small-vessel lesions in the fronto-subcortical brain network. These sub-studies were conducted as part of the Helsinki Stroke Aging Memory (SAM) study. The SAM cohort consisted of 486 consecutive patients aged 55 to 85 years who were admitted to Helsinki University Central Hospital with acute ischemic stroke. The study included comprehensive clinical, neuropsychological, psychiatric and radiological assessment three months poststroke. The patients were followed up up for 12 years using extensive national registers. The effect of different manifestations of cerebral SVD on poststroke survival and stroke recurrence was analyzed controlling for factors such as age, education, and cardiovascular risk factors. Poststroke dementia and cognitive impairment relate to poor long-term survival. In particular, deficits in executive functions as well as visuospatial and constructional abilities predict poor outcome. The predictive value of cognitive deficits is further underlined by the finding that depression-executive dysfunction syndrome (DES), but not depression in itself, is associated with poor poststroke survival. Delirium is not independently associated with increased risk for long-term poststroke mortality, although it is associated with poststroke dementia. Furthermore, acute index stroke attributable to SVD is associated with poorer long-term survival and a higher risk for cardiac death than other stroke subtypes. Severe WMC, a surrogate of SVD, is independently related to an increased risk of stroke recurrence at five years. In summary, cognitive poststroke outcomes reflecting changes in the executive network brain, and the presence of cerebral SVD are important determinants of poststroke mortality and ischemic stroke recurrence, regardless of whether SVD is the cause of the index stroke or a condition concurrent to some other etiology.

Ekotuotteet kuluttajan arjessa – vastuullisuutta, puhtautta ja arjen luksusta

Tutkielmassa tarkastellaan kuluttajien näkemyksiä ekotuotteiden valintaan vaikuttavista tekijöistä. Analysoin ekotuotteiden hankintaa kolmen teeman kautta. Ne ovat vihreys ja vastuullisuus, puhtaus tuotevalinnoissa sekä niin sanottu arjen luksus. Tutkimukseni empiirinen osa koostuu 10 teemahaastattelusta. Tutkimuskohteena on ekokauppa Ruohonjuuressa ostoksiaan tekevät kuluttajat. Haastateltavia etsin ilmoituksella ekokauppa Ruohonjuuresta sekä kaupan Facebook-sivuilta. Lisäksi oma haastattelupäivä Ruohonjuuren myymälässä tuotti haastateltavia mukaan tutkimukseen. Kirjoitin haastatteluista yhteenvedon ja analysoin aineistoa teemoittelun avulla. Nykyiset ympäristöongelmat vaikuttavat siihen, millaisena koemme arjen tulevaisuudessa. Vihreä ja vastuulllinen kuluttaja ottaa huomioon kulutuspäätöksiensä vaikutukset ympäristöön. Vihreät kulutuspäätökset tarkoittavat kestäviä kulutustapoja kuten jätteiden lajittelua, kirpputorikierrättämistä ja ympäristöä säästävien ekotuotteiden valintaa. Aineiston perusteella voi todeta, että ekotuotteiden ympäristömyönteisyyteen liitetään läheisesti luomutuotanto ja luomutuotteet. Ekotuotteet nähdään myös eettisinä ja moraalisina valintoina, joiden avulla halutaan vaikuttaa myös muiden hyvinvointiin. Ekotuotteisiin kohdistuu siten monenlaisia odotuksia, mutta myös epäilyjä. Aineistoni perusteella tuotetta ei välttämättä koettu ekotuotteeksi, jos sen valmistamiseen on käytetty paljon resursseja. Kuluttajat ovat kiinnostuneita ruoan alkuperästä ja sen aitoudesta. Ekotuotteet koetaan muita tuotteita päinvastoin puhtaiksi vaihtoehdoiksi. Puhtaus ekotuotteissa mielletään laadultaan turvallisiksi ja terveellisiksi tuotteiksi, jotka maistuvat hyvältä.

Shoppailu ekokaupassa voi olla nautinnollista ja miellyttävää toimintaa, vaikka ostamista vain harkitaan. Ekotuote lahjana kertoo lahjan antajasta ja tuo lahjan saajalle palan luksusta vaikkapa luomusuklaan muodossa.

Oral health and kidney disease with emphasis on diabetic nephropathy

Chronic kidney disease (CKD) is a worldwide health problem, with adverse outcomes of cardiovascular disease and premature death. The ageing of populations along with the growing prevalence of chronic diseases such as diabetes and hypertension is leading to worldwide increase in the number of CKD patients. It has become evident that inflammation plays an important role in the pathogenesis of atherosclerosis complications. CKD patients also have an increased risk of atherosclerosis complications (including myocardial infarction, sudden death to cardiac arrhythmia, cerebrovascular accidents, and peripheral vascular disease). In line with this, oral and dental problems can be an important source of systemic inflammation. A decline in oral health may potentially act as an early marker of systemic disease progression. This series of studies examined oral health of CKD patients from predialysis, to dialysis and kidney transplantation in a 10-year follow-up study and in a cross-sectional study of predialysis CKD patients. Patients had clinical and radiographic oral and dental examination, resting and stimulated saliva flow rates were measured, whilst the biochemical and microbiological composition of saliva was analyzed. Lifestyle and oral symptoms were recorded using a questionnaire, and blood parameters were collected from the hospital records. The hypothesis was that the oral health status, symptoms, sensations, salivary flow rates and salivary composition vary in different renal failure stages and depend on the etiology of the kidney disease. No statistically significant difference were seen in the longitudinal study in the clinical parameters. However, some saliva parameters after renal transplantation were significantly improved compared to levels at the predialysis stage. The urea concentration of saliva was high in all stages. The salivary and plasma urea concentrations followed a similar trend, showing the lowest values in kidney transplant patients. Levels of immunoglobulin (Ig) A, G and M all decreased significantly after kidney transplantation. Increased concentrations of IgA, IgG and IgM may reflect disintegration of the oral epithelium and are usually markers of poor general oral condition. In the cross-sectional investigation of predialysis CKD patients we compared oral health findings of diabetic nephropathy patients to those with other kidney disease than diabetes. The results showed eg. more dental caries and lower stimulated salivary flow rates in the diabetic patients. HbA1C values of the diabetic patients were significantly higher than those in the other kidney disease group. A statistically significant difference was observed in the number of drugs used daily in the diabetic nephropathy group than in the other kidney disease group. In the logistic regression analyses, age was the principal explanatory factor for high salivary total protein concentration, and for low unstimulated salivary flow. Poor dental health, severity of periodontal disease seemed to be an explanatory factor for high salivary albumin concentrations. Salivary urea levels were significantly linked with diabetic nephropathy and with serum urea concentrations. Contrary to our expectation, however, diabetic nephropathy did not seem to affect periodontal health more severely than the other kidney diseases. Although diabetes is known to associate with xerostomia and other oral symptoms, it did not seem to increase the prevalence of oral discomfort. In summary, this series of studies has provided new information regarding the oral health of CKD patients. As expected, the commencement of renal disease reflects in oral symptoms and signs. Diabetic nephropathy, in particular, appears to impart a requirement for special attention in the oral health care of patients suffering from this disease.
