In this study I consider what kind of perspective on the mind body problem is taken and can be taken by a philosophical position called non-reductive physicalism. Many positions fall under this label. The form of non-reductive physicalism which I discuss is in essential respects the position taken by Donald Davidson (1917-2003) and Georg Henrik von Wright (1916-2003). I defend their positions and discuss the unrecognized similarities between their views. Non-reductive physicalism combines two theses: (a) Everything that exists is physical; (b) Mental phenomena cannot be reduced to the states of the brain. This means that according to non-reductive physicalism the mental aspect of humans (be it a soul, mind, or spirit) is an irreducible part of the human condition. Also Davidson and von Wright claim that, in some important sense, the mental aspect of a human being does not reduce to the physical aspect, that there is a gap between these aspects that cannot be closed. I claim that their arguments for this conclusion are convincing. I also argue that whereas von Wright and Davidson give interesting arguments for the irreducibility of the mental, their physicalism is unwarranted. These philosophers do not give good reasons for believing that reality is thoroughly physical. Notwithstanding the materialistic consensus in the contemporary philosophy of mind the ontology of mind is still an uncharted territory where real breakthroughs are not to be expected until a radically new ontological position is developed. The third main claim of this work is that the problem of mental causation cannot be solved from the Davidsonian - von Wrightian perspective. The problem of mental causation is the problem of how mental phenomena like beliefs can cause physical movements of the body. As I see it, the essential point of non-reductive physicalism - the irreducibility of the mental - and the problem of mental causation are closely related. If mental phenomena do not reduce to causally effective states of the brain, then what justifies the belief that mental phenomena have causal powers? If mental causes do not reduce to physical causes, then how to tell when - or whether - the mental causes in terms of which human actions are explained are actually effective? I argue that this - how to decide when mental causes really are effective - is the real problem of mental causation. The motivation to explore and defend a non-reductive position stems from the belief that reductive physicalism leads to serious ethical problems. My claim is that Davidson's and von Wright's ultimate reason to defend a non-reductive view comes back to their belief that a reductive understanding of human nature would be a narrow and possibly harmful perspective. The final conclusion of my thesis is that von Wright's and Davidson's positions provide a starting point from which the current scientistic philosophy of mind can be critically further explored in the future.

Tutkielmassa esitellään ja arvioidaan John Searlen teoriaa tietoisuudesta. Tietoisuus (consciousness) on Searlen mukaan tärkein mielenfilosofinen käsite. Searle ei määrittele käsitettä tarkasti, vaan tyytyy esittämään sitä kuvaavia esimerkkejä ja analogioita. Tietoisuuden keskeisimmiksi ominaisuuksiksi Searlen teoriassa näyttävät muodostuvan intentionaalisuus (intentionality), subjektiivisuus (subjectivity) ja kausaalinen vaikutus käyttäytymiseen (mental causation). Näihin ominaisuuksiin liittyvät myös Searlen painavimmat tietoisuudesta esittämät argumentit. Argumenttien analysointi on tutkielman tärkein tavoite. Searlen yhteysperiaatteen (Connection Principle) mukaan intentionaalisia tiloja voi olla vain olennolla, jolla voi olla tietoisia intentionaalisia tiloja, ja jokainen alitajuinen intentionaalinen tila on ainakin potentiaalisesti tietoinen. Toisin sanoen intentionaalisuuden ja tietoisuuden välillä vallitsee välttämätön yhteys seuraavasti: on loogisesti välttämätöntä, että jokainen intentionaalinen tila voi ainakin periaattessa päästä tietoisuuteen.Tutkielmassa kuitenkin osoitetaan, että yhteysperiaateeseen on syytä suhtautua epäillen. Searlen yhteysperiaatteen puolesta esittämä argumentti näyttää nimittäin sisältävän dilemman. Jos erottelu intrinsiseen ja näennäiseen intentionaalisuuteen tulkitaan Searlen tavoin, syyllistytään sen olettamiseen, mikä pitäisi todistaa; jos taas erottelu tulkitaan toisin kuin Searle, argumentti ei tue yhteysperiaatetta. Searlen mukaan mentaaliset tilat ovat aina jonkun mentaalisia tiloja. Tästä väitteestä Searle pyrkii johtamaan toisen, paljon radikaalimman väitteen: mielen ilmiöt kuuluvat omaan ontologiseen kategoriaansa, subjektiivisten mentaalisten tilojen kategoriaan. Searlen käsitystä tukee Thomas Nagelin esittämä, hyvin samansisältöinen argumentti. Yksimielisyys ei kuitenkaan ole erehtymättömyyden tae, sillä Paul Churchlandin kritiikki näyttää pahasti horjuttavan Searlen subjektiivisuusargumentin uskottavuutta. Churchland väittää Searlen syyllistyvän intensionaaliseen virhepäätelmään. Yksittäisen henkilön episteemisen pääsyn rajoittuneisuudesta ei Churchlandin mukaan voida tehdä mitään ontologisia johtopäätöksiä, koska tiedetyksi tuleminen ei ole objektin aito ominaisuus. Vastaväite näyttää olevan kohtalokas Searlen subjektiivisuusargumentille. Subjektiivisuuden ongelma näyttää olevan perustava metafyysinen vedenjakaja, joka jakaa mielenfilosofiset teoriat toisaalta materialistisiin, toisaalta dualistisiin. Searle uskoo, että mieli-ruumis -ongelma (mind-body problem) on ratkaistavissa ilman, että tarvitsee valita kumpaakaan. Ratkaisu sisältyy kahteen Searlen näennäisesti yhteensopimattomaan teesiin. Ensimmäisen teesin mukaan mentaaliset tilat ovat todellisia ilmiöitä, eikä niitä voida redusoida mihinkään muuhun tai eliminoida määrittelemällä ne uudestaan. Toisen teesin mukaan aivojen operaatiot aiheuttavat mentaaliset tilat ja mentaaliset tilat ovat aivojen piirteitä. Teeseistä jälkimmäinen osoittautuu ongelmalliseksi syistä, jotka Jaegwon Kim on esittänyt. Jos mentaaliset tilat olisivat aivojen ominaisuuksia, ei mielen ja aivojen välinen suhde voisi olla kausaalinen, koska kausaatiossa (causation) on aina kyse kahden erillisen entiteetin tai tapahtuman välisestä relaatiosta, jossa suhteen osapuolien välillä on oltava ajallista etäisyyttä. Toiseksi Searlen vertaus tietoisuuden ja aivojen suhteesta kappaleen kiinteyden ja sen mikrorakenteen suhteeseen epäonnistuu, koska tietoisuus ja kiinteys kuuluvat Searlen teoriassa eri ontologisiin kategorioihin, eikä niitä siten voi ongelmattomasti rinnastaa. Searlen analogia kiinteyteen murtuu myös siksi, että kappaleen mikrorakenne ei yksinkertaisesti aiheuta sen kiinteyttä. Tietoisuus ei siis voi olla samanaikaisesti aivojen ominaisuus ja aivojen kausaalisen toiminnan seuraus. Tutkielmassa päädytään puolustamaan kantaa, että Searlen argumentit eivät ole vakuuttavia ja että Searle ei ole onnistunut eksplikoimaan teoriaa, joka välttäisi dualismiin ja materialismiin liittyvät tunnetut ongelmat. Kysymys mikä on mielen suhde ruumiiseen, jää siten avoimeksi. Avainsanat: intentionaalisuus, mentaalinen, mieli-ruumis -ongelma, Searle, subjektiivisuus, tietoisuus

Former President of Finland Urho Kekkonen was not only a powerful politician but also a well-known sportsman and keep-fit enthusiast. The president’s sports hobbies were covered and celebrated in the media and thus became an integral part of his public persona. This paper looks at Kekkonen’s athletic and able-bodied image and its significance for his power from the perspective of gender. In his exercise activities, Kekkonen was able to display his bodily prowess and demonstrate his version of masculinity, which emphasized both physical and mental strength. The union of mind and muscle in turn buttressed his political ascendancy. Kekkonen’s athletic body served as a cornerstone of his dominance over his country and, simultaneously, as a shield protecting Finland from both internal and external threats. Furthermore, Kekkonen’s sports performances were essential elements in the myth that was created around the president during his term and which was carefully conserved after his fall from power. Drawing upon scholarship on men and masculinities, this paper reassesses the still-effective mythical image of Kekkonen as an invincible superman. The article reveals the performative nature of his athletic activities and shows that in part, his pre-eminence in them was nothing more than theatre enacted by him and his entourage. Thus, Kekkonen’s superior and super-masculine image was actually surprisingly vulnerable and dependent on the success of the performance. The president’s ageing, in particular, demonstrates the fragility of his displays of prowess, strength and masculinity, and shows how fragile the entanglement of body and power can be.

Luce Irigaray is a Belgian-born philosopher, psychoanalyst and linguist. Irigaray s concept of woman is crucial for understanding her own work but also for examining and developing the theoretical and methodological basis of feminist theory. This thesis argues that, ultimately, Irigaray s exploration of woman s being challenges our traditional notion of philosophy as a neutral discourse and the traditional notion of ourselves as philosophizing persons or human beings. However, despite its crucial role, Irigaray s idea of woman still lacks a comprehensive explication. This is because the discourse of sexual difference is blurred by the ideas of essentialism and biologism. --- Irigaray s concept of woman has been interpreted and criticized from the perspectives of metaphysical essentialism, strategic essentialism, realist essentialism and deconstructionism. This thesis argues that a reinterpretation is necessary to account for Irigaray s claims about the the traditional woman , mimesis, the specificity of the feminine body, feminine expression and sexual difference. Moreover, any reading should account for the differences between women and avoid giving a prescriptive function to the essence of woman. --- My thesis develops a new interpretation of Irigaray s concept of woman on the basis of the phenomenology of the body. It argues that Irigaray s discourse on woman can and must be understood by an idea of existential style. Existential style is embodied, affective and spiritual and it is constituted in relation to oneself, to others and to the world. It is temporal, it evolves and changes but preserves its open unity in its transformations. Stylistic unities, such as femininity or philosophy, are constituted in and by the singulars. -- This study discusses and analyses feminine existential style as a central theme and topic of Irigaray s works and shows how her work operates as a primary and paradigmatic example of the feminine style. These tasks are performed by studying the mimetic positions available for women and by explicating the phenomenological background of Irigaray s conceptions of the philosophical method, and the lived, expressive and affective body. The critical occupation and transformation of these mimetic positions, the inquiry into the first-person pre-discursive experience, and the cultivation of feminine expressivity open up the possibility of becoming a woman writer, a woman lover and a woman philosopher. The appearance of these new feminine figures is a precondition for the realization of sexual difference. So Irigaray opens up the possibility of sexual difference by instituting and constituting a feminine subject of love and wisdom, and by problematizing the idea of a neutral and absolute subject.

Aims. The main meals that youngsters have during the day are eaten at home and at school. In the Nordic countries breakfast and supper are often eaten with other members of the family. The way that Nordic countries arrange the school lunch and the frequency of family meals differ between countries. However, the challenges related to eating habits of the young are surprisingly similar. The aim of this study is to discuss how the Nordic countries could support youngsters’ healthy eating habits. This study was carried out as a part of a Nordic research project and it completed the work done by Kauppinen (2009) and Niemi (2009) in their Master’s Theses. The research questions are: 1. How do the youngsters evaluate their own eating habits and those of their family? 2. How do the youngsters evaluate the influence of home, family and school on their own eating habits? 3. What kind of relationship exists between eating at home and at school according to the data? Data and methods. A quantitative internet-based survey was used to collect data (N=1539) on the 9th graders conceptions and understandings. The survey consisted of respondents from Finland (N=586), Sweden (N=427), Denmark (N=295) and Norway (N=246). In this study the whole data to the appropriate extent was analyzed. The analysis was done with the SPSS-software and included examination of means, standard deviations, cross-tabulations, Pearson´s correlations, Chi-squared -tests, t-tests and one-way analysis of variance (ANOVA). The results were compaired between the countries and between sexes. Results and discussion. The studied youngsters evaluated their own eating habits positively. There were statistically signifigant differences (p< .05) between countries concerning the people who influence the youngsters’ healthy eating habits. Youngsters from Finland and Sweden considered making healthy choices at school easier than those from Denmark and Norway. Also eating a so called healthy lunch at school was more common in Finland and in Sweden. Eating breakfast and eating a healthy meal at school had a statistically significant interconnection (p< .001). The differences between sexes were not equal between the countries. The results supported those from previous studies, but also raised ideas for further study. Youngsters’ near environments should support their possibilities to make healthy choices and to participate to the decicion making process. Co-operation between the Nordic countries and between the home and the school is important. Listening to the youngsters’ own voice is a challence and a possibility for developing both home economics education and research in this area. Key words: Nordic countries, youngsters, healthy eating habits, eating at home, school meals

Purpose This study focused on craft from a standpoint of phenomenological philosophy and craft was interpreted through Maurice Merleau-Ponty’s phenomenology of the body. The main focus was the physical phase of the craft process, wherein a product is made from material. The aim was to interpret corporality in craft. There is no former research focusing on lived body in craft science. Physical, bodily making is inalienable in craft, but it is not articulated. Recent discussion has focused on craft as ”whole”, which emphasizes designing part in the process, and craft becomes conceptualized with the theories of art and design. The axiomatic yet silenced basis of craft, corporality, deserves to become examined as well. That is why this study answers the questions: how craft manifests in the light of phenomenology of the body and what is corporality in craft? Methods In this study I cultivated a phenomenological attitude and turned my exploring eye on craft ”in itself”. In addition I restrained myself from mere making and placed myself looking at the occurrence of craft to describe it verbally. I read up Maurice Merleau-Ponty’s phenomenology of the body on his principal work (2002) and former interpretations of it. Interpreting and understanding textual data were based on Gadamer’s hermeneutics, and the four-pronged composition of the study followed Koski’s (1995) version of the Gadamerian process of textual interpretation. Conclusions In the construction of bodily phenomenology craft was to be contemplated as a mutual relationship between the maker and the world materializing in bodily making. At the moment of making a human being becomes one with his craft, and the connection between the maker, material and the equipment appears as communication. Operational dimension was distinctive in the intentionality of craft, which operates in many ways, also in craft products. The synesthesia and synergy of craft were emphasized and craft as bodily practice came to life through them. The moment of making appeared as situation generating time and space, where throwing oneself into making may give the maker an experience of upraise beyond the dualism of mind and body. The conception of the implicit nature of craft knowledge was strengthened. In the light of interpretation it was possible to conceptualize craft as a performance and making ”in itself” as a work of art. In that case craft appeared as bodily expression, which as an experience approaches art without being it after all. The concept of aesthetic was settled into making as well. Bodily and phenomenological viewpoint on craft gave material to critically contemplate the concept of “whole craft” (kokonainen käsityö) and provided different kind of understanding of craft as making.

Theory of developmental origins of adult health and disease proposes that experiences during critical periods of early development may have consequences on health throughout a lifespan. Thesis studies aimed to characterize associations between early growth and some components of the metabolic syndrome cluster. Participants belong to two epidemiological cohorts with data on birth measurements and, for the younger cohort, on serial recordings of weight and height during childhood. They were born as singletons between 1924-33 and 1934-44 in the Helsinki University Central Hospital, and 500 and 2003 of them, respectively, attended clinical studies at the age of 65-75 and 56-70 years, respectively. In the 65-75 year old men and women, the well-known inverse relationship between birth weight and systolic blood pressure (SBP) was confined to people who had established hypertension. Among them a 1-kg increase in birth weight was associated with a 6.4-mmHg (95% CI: 1.0 to 11.9) decrease in SBP. This relationship was further confined to people with the prevailing Pro12Pro polymorphism of the peroxisome proliferator-activated receptor-γ2 (PPARγ2) gene. People with low birth weight were more likely to receive angiotensin-converting enzyme inhibitors/angiotensin-receptor blockers (ACEI/ARB, p=0.03), and, again, this relationship was confined to the carriers of the Pro12Pro (p=0.01 for interaction). These results suggest that the inverse association between birth weight and systolic BP becomes focused in hypertensive people because pathological features of BP regulation, associated with slow fetal growth, become self-perpetuating in adult life. Insulin resistance of the Pro12Pro carriers with low birth weight may interact with the renin-angiotensin system leading to raised BP levels. Habitual physical activity protected men and women who were small at birth, and thus at increased risk for the development of type 2 diabetes, against glucose intolerance more strongly. Among subjects with birth weight ≤3000 g, the odds ratio (OR) for glucose intolerance was 5.2 (95% CI: 2.1 to 13) in those who exercised less than 3 times per week compared to regular exercisers; in those who scored their exercise light compared with moderate exercisers (defined as comparable to brisk walking) the OR was 3.5 (1.5 to 8.2). In the 56-70 year old men a 1 kg increase in birth weight corresponded to a 4.1 kg (95% CI: 3.1 to 5.1) and in women to a 2.9 kg (2.1 to 3.6) increase in adult lean mass. Rapid gain in body mass index (BMI), i.e. crossing from an original BMI percentile to a higher one, before the age of 2 years increased adult lean mass index (LMI, lean mass/height squared) without excess fat accumulation whereas rapid gain in BMI during later childhood, despite the concurrent rise in LMI, resulted in a relatively higher increase in adult body fat mass. These findings illustrate how genes, the environment and their interactions, early growth patterns, and adult lifestyle modify adult health risks which originate from early life.

Individual movement is very versatile and inevitable in ecology. In this thesis, I investigate two kinds of movement body condition dependent dispersal and small-range foraging movements resulting in quasi-local competition and their causes and consequences on the individual, population and metapopulation level. Body condition dependent dispersal is a widely evident but barely understood phenomenon. In nature, diverse relationships between body condition and dispersal are observed. I develop the first models that study the evolution of dispersal strategies that depend on individual body condition. In a patchy environment where patches differ in environmental conditions, individuals born in rich (e.g. nutritious) patches are on average stronger than their conspecifics that are born in poorer patches. Body condition (strength) determines competitive ability such that stronger individuals win competition with higher probability than weak individuals. Individuals compete for patches such that kin competition selects for dispersal. I determine the evolutionarily stable strategy (ESS) for different ecological scenarios. My models offer explanations for both dispersal of strong individuals and dispersal of weak individuals. Moreover, I find that within-family dispersal behaviour is not always reflected on the population level. This supports the fact that no consistent pattern is detected in data on body condition dependent dispersal. It also encourages the refining of empirical investigations. Quasi-local competition defines interactions between adjacent populations where one population negatively affects the growth of the other population. I model a metapopulation in a homogeneous environment where adults of different subpopulations compete for resources by spending part of their foraging time in the neighbouring patches, while their juveniles only feed on the resource in their natal patch. I show that spatial patterns (different population densities in the patches) are stable only if one age class depletes the resource very much but mainly the other age group depends on it.

Portable music players have made it possible to listen to a personal collection of music in almost every situation, and they are often used during some activity to provide a stimulating audio environment. Studies have demonstrated the effects of music on the human body and mind, indicating that selecting music according to situation can, besides making the situation more enjoyable, also make humans perform better. For example, music can boost performance during physical exercises, alleviate stress and positively affect learning. We believe that people intuitively select different types of music for different situations. Based on this hypothesis, we propose a portable music player, AndroMedia, designed to provide personalised music recommendations using the user’s current context and listening habits together with other user’s situational listening patterns. We have developed a prototype that consists of a central server and a PDA client. The client uses Bluetooth sensors to acquire context information and logs user interaction to infer implicit user feedback. The user interface also allows the user to give explicit feedback. Large user interface elements facilitate touch-based usage in busy environments. The prototype provides the necessary framework for using the collected information together with other user’s listening history in a context- enhanced collaborative filtering algorithm to generate context-sensitive recommendations. The current implementation is limited to using traditional collaborative filtering algorithms. We outline the techniques required to create context-aware recommendations and present a survey on mobile context-aware music recommenders found in literature. As opposed to the explored systems, AndroMedia utilises other users’ listening habits when suggesting tunes, and does not require any laborious set up processes.
