Philosophy as a Path to Happiness : Attainment of Happiness in Arabic Peripatetic and Ismaili Philosophy

The aim of the dissertation is to explore the idea of philosophy as a path to happiness in classical Arabic philosophy. The starting point is in comparison of two distinct currents between the 10th and early 11th centuries, Peripatetic philosophy, represented by al-Fārābī and Ibn Sīnā, and Ismaili philosophy represented by al-Kirmānī and the Brethren of Purity. They initially offer two contrasting views about philosophy in that the attitude of the Peripatetics is rationalistic and secular in spirit, whereas for the Ismailis philosophy represents the esoteric truth behind revelation. Still, they converge in their view that the ultimate purpose of philosophy lies in its ability to lead man towards happiness. Moreover, they share a common concept of happiness as a contemplative ideal of human perfection, which refers primarily to an otherworldly state of the soul s ascent to the spiritual world. For both the way to happiness consists of two parts: theory and practice. The practical part manifests itself in the idea of the purification of the rational soul from its bodily attachments in order for it to direct its attention fully to the contemplative life. Hence, there appears an ideal of philosophical life with the goal of relative detachment from the worldly life. The regulations of the religious law in this context appear as the primary means for the soul s purification, but for all but al-Kirmānī they are complemented by auxiliary philosophical practices. The ascent to happiness, however, takes place primarily through the acquisition of theoretical knowledge. The saving knowledge consists primarily of the conception of the hierarchy of physical and metaphysical reality, but all of philosophy forms a curriculum through which the soul gradually ascends towards a spiritual state of being along an order that is inverse to the Neoplatonic emanationist hierarchy of creation. For Ismaili philosophy the ascent takes place from the exoteric religious sciences towards the esoteric philosophical knowledge. For Peripatetic philosophers logic performs the function of an instrument enabling the ascent, mathematics is treated either as propaedeutic to philosophy or as a mediator between physical and metaphysical knowledge, whereas physics and metaphysics provide the core of knowledge necessary for the attainment of happiness.

Charred seeds in Mikkeli Orijärvi : A study of subsistence strategies of an Iron Age settlement in East Finland

In this study the over 350 macrofossil samples, containing over 2300 charred plant remains from an Iron Age settlement containing fossil fields in Mikkeli Orijärvi Kihlinpelto, were studied archaeobotanically. The aim was to get more information about subsistence strategies, especially agriculture and study differences in the plant combinations in the different structures and use the archaeobotanical theory to interpret these structures. The methodological question was to study the taphonomy of the charred plant material. The results gave a diverse impression of the agriculture and subsistence strategies of the settlement in Orijärvi, where barley was the most important cereal with rye, wheat and oat cultivated as minor crops. The arable weed assemblage indicates that the fields were situated in different kinds of soils and the crops were cultivated when different kind of weather conditions were prevailing. Ergot was found with the cereals, and it was growing on some of the arable crops and it also indicates wet climate. Hemp and flax were cultivated and wild plants were collected. The meadow and wetland plants found in the material derive most probably from animal fodder. Tubers of bulbous oat-grass were interesting, because they are usually found in graves. Comparison with other Iron Age settlements and graves indicates that the plant material found from the ancient field layers derives most probably from dwellings and graves, which were taken into cultivation.

Svekofennialaisen orogenian ylityönnön terminen mallinnus Itä-Suomen arkeeisella kratonilla

This study reviews the thermophysical properties of rocks and the lithosphere and describes a one dimensional thermal numeric model of hypothetical 20 km thick overthrust plate obtruded on to the Archeaen craton in the Svecofennian orogeny (1.92-1.77 Ga). The objective is to find out if the overthrust plate and its radiogenic heat sources were able to produce the thermal effects observed on the current erosion level of the Archaean craton. Heat transfer in lithosphere is assumed conductive, and advective heat transfer due to melting and melt transfer is supposed negligible. The study area is located in the Eastern Finland, approximately current Kainuu and Northern Karelia regions, east from the most active orogenic belt (Raahe-Ladoga zone), so that orogenic magmatism can be neglected. Physical parameters and boundary conditions for the model are from different earlier published sources: deep seismic profiles (rock variation in depth), laboratory measurements (heat production and conductivity of rocks), field measurements (heat flow densities), and pT(t) estimations from the Finnish precambrian to estimate the size and thickness of the sheet. Comparison of the modelling results to previous K-Ar datings and other pTt estimations show, that the effect of the overthrust sheet has been adequate (max. T 450°C at 4 kbar) to produce the K-Ar resetting ages measured from the Archaean bedrock at current erosion level. No other kind of thermal activation in lithosphere is required. Results show possibly very minor partial melting in upper middle crust underneath the overthrust sheet.

Arrested Drunk Drivers : Trends, social background, recidivism and mortality

The aim of this study was to examine the trends, incidence and recidivism of drunken driving during a 20-year period (1988 - 2007) using the data on all suspected drunken driving in this period. Furthermore, the association between social background and drunken driving, and the mortality of drunk drivers were studied by using administrative register data provided by Statistics Finland. The study was completely register-based. In 1989 - 1991, every year 30,000 drivers were suspected of drunken driving, but the number fell to less than 20,000 by 1994, during the economic recession. The changes in the arrest incidence of the youngest age groups were especially pronounced, most of all in the age group of 18 - 19-year olds. Even though the incidence among youth decreased dramatically, their incidence rate was still twice that of the general population aged 15 - 84 years. Drunken driving was associated with a poor social background among youth and working-aged men and women. For example, a low level of education, unemployment, divorce, and parental factors in youth were associated with a higher risk of being arrested for drunken driving. While a low income was related to more drunken driving among working-aged people, the effect among young persons was the opposite. Every third drunk driver got rearrested during a 15-year period, whereas the estimated rearrest rate was 44%. Findings of drugs only or in combination with alcohol increased the risk of rearrest. The highest rearrest rates were seen among drivers who were under the influence of amphetamines or cannabis. Also male gender, young age, high blood alcohol concentration, and arrest during weekdays and in the daytime predicted rearrest. When compared to the general population, arrested drunk drivers had significant excess mortality. The greatest relative differences were seen in alcohol-related causes of death (including alcohol diseases and alcohol poisoning), accidents, suicides and violence. Also mortality due to other than alcohol-related diseases was elevated among drunk drivers. Drunken driving was associated with multiple factors linked to traffic safety, health and social problems. Social marginalization may expose a person to harmful use of alcohol and drunken driving, and the associations are seen already among the youth. Recidivism is common among drunk drivers, and driving under the influence of illicit and/or medicinal drugs is likely to indicate worse substance abuse problems, judging from the high rearrest rates. High alcohol-related mortality in this population shows that drunken driving is clearly an indicator of alcohol abuse. More effective measures of preventing alcohol-related harms are needed, than merely preventing convicted drunk drivers from driving again.

Sopivasti työtä ja vapaa-aikaa? Tutkimuksia ajankäytöstä eri elämäntilanteissa

Tutkimuksessa tarkastellaan erilaisissa sosiaalipoliittisesti kiinnostavissa elämäntilanteissa olevien ihmisten ajankäyttöä ja siinä 1990-luvulla tapahtuneita muutoksia. Tutkimuksen neljästä erillisartikkelista kolmessa analysoidaan työttömien nuorten, perheenisien ja eläkeläisten ajankäyttöä Tilastokeskuksen vuosina 1979, 1987–1988 ja 1999–2000 keräämien ajankäyttöaineistojen pohjalta. Neljännessä artikkelissa tarkastellaan pohjoismaalaisten työntekijöiden tyytyväisyyttä ajankäytön jakautumiseen työn ja vapaa-ajan kesken European Social Survey -kyselyaineiston pohjalta. Tutkimuksen tulokset osoittavat, että osin eri, mutta osin myös samat tekijät vaikuttavat eri elämäntilanteissa olevien yksilöiden ajankäyttöön. Keskeisiä ajankäyttöön vaikuttavia tekijöitä ovat tulot ja perhetilanne: pienet tulot ja pienet lapset rajoittavat omalla tavallaan ajankäyttöä. Sosiaalipolitiikan rooli yksilöiden ja sitä kautta perheiden ja kokonaisten yhteisöjen ajankäytössä on suuri. Ajankäytön valintoihin vaikuttavat luonnollisesti yksilöiden omat preferenssit, mutta valinnat kuvastavat aina myös ympäröivän yhteiskunnan institutionaalisia rakenteita. Onpa kyse sitten työttömän, työssä käyvän, lapsiperheen tai eläkeläiskotitalouden ajankäytöstä, ajankäyttöä ohjaavat erinäiset lait ja normit. Ajankäytön näkökulmasta ei siten ole yhdentekevää, millaista perhe-, työvoima- ja tulonjakopolitiikkaa yhteiskunnassa toteutetaan.

Kaakkois-Suomen lapinraunioiden ikä ja kulttuurikonteksti

Lapinrauniot ovat Järvi-Suomen varhaismetallikautiseen (n. 1900 eaa.-300 jaa.) pyyntiväestöön yhdistettyjä kiviröykkiöitä. Tavallisesti ne esiintyvät yksittäisinä tai korkeintaan muutaman röykkiön ryhminä. Monista lapinraunioita on löytynyt palanutta ihmisen luuta ja joistakin myös hauta-anneiksi tulkittuja esineitä. Osasta ei ole kyetty paikallistaman mitään merkkejä hautauksesta. Jotkut ovat vaikuttaneet löytöjensä perusteella uhriröykkiöiltä. Tässä tutkielmassa selvitellään Etelä-Savon, Etelä-Karjalan ja Pohjois-Kymenlaakson lapinraunioiden ikää ja kulttuuri-kontekstia uusien lapinraunioajoitusten, alueelta aiemmin saatujen luonnontieteellisten ajoitusten ja sijaintitutki-musten avulla. Luonnontieteellisen keskusmuseon ajoituslaboratoriossa teetettiin tutkielmaa varten AMS-ajoitukset tutkimusalueen kolmesta riittävästi luulöytöjä tuottaneesta lapinrauniosta. Sijaintitutkimuksia toteutettiin suorittamalla tilastollisia vertailuja kaikkien tutkimusalueen lapinraunioiden sijoittumisesta suhteessa tekstiilikeramiikkaa (n. 1900-500 eaa.) ja/tai Sär2-keramiikkaa (n. 900 eaa. 300 jaa.) sisältäviin asuinpaikkakohteisiin. AMS-ajoitusten perusteella Iitin Hiidensalmen palanutta luuta, kvartsi-iskoksia ja astiamaisen luonnonkiven sisältänyt lapinraunio on rakennettu 1505-1385 eaa., Ristiinan Haukkavuoren palanutta luuta sisältänyt lapinraunio 1450-1305 eaa. ja Savonlinnan Häyrynjärvi A:n lapinrauniokohteen palanutta luuta, kvartsi-iskoksia sekä Sär2-keramiikan siruja sisältänyt röykkiö kaksi 415-230 eaa. Ajoitustulokset osoittavat, että lapinrauniorakentaminen on omaksuttu Järvi-Suomen kaakkoisosissa jo varhaismetallikauden alussa. Yhdessä aiempien lapinraunioajoitusten kanssa tämä viittaa siihen, että röykkiörakentaminen ei ole levinnyt Järvi-Suomen alueelle lounaisen Suomen pronssikautisesta rannikkokulttuurista (n. 1500-500 eaa), vaan sen taustalta löytyy luultavammin Perämeren rannikolla jo kivikaudella harjoitettu röykkiörakentaminen, jota ei ole kyetty yhdistämään minkäänlaisiin hautausrituaaleihin. Ajoitukset myös vahvistavat hypoteesia, jonka mukaan lapinrauniotradition varhaisvaiheisiin ei ole kuulunut esineiden eikä keramiikan laittaminen röykkiöihin. Ajoitusten vertailu tutkimusalueen aiempiin arkeologisiin ajoituksiin osoittaa, että lapinrauniot eivät ainakaan heti korvanneet maalauskallioita rituaalipaikkoina, vaan kalliomaalausten luona suoritettiin uhrirituaaleja vielä lapinrauniotradition omaksumisen jälkeen. Pienimuotoista kaskiviljelyä on harjoitettu alueella jo ennen lapinrauniorakentamisen omaksumista, mutta pyynti pysyi alueen pääelinkeinona ilmeisesti koko varhaismetallikauden. Varhaismetallikautiset asuinpaikat ovat alueella tyypillisesti leirimäisiä, mikä viittaa harvaan ja liikkuvaan asutukseen. Tutkimusalueen lapinrauniot ja tekstiilikeramiikkaa/Sär2-keramiikkaa sisältävät asuinpaikat ovat tässä tutkielmassa suoritettujen sijaintitutkimusten perusteella keskittyneet toistensa läheisyyteen, vaikka kaikkien lapinraunioiden läheisyydestä ei varhaismetallikautista asuinpaikkaa löydykään. Erityisen usein lapinraunioiden läheisyydessä näyttävät sijaitsevan asuinpaikat, joista on löydetty sekä tekstiilikeramiikkaa että Sär2-keramiikkaa. Tämä viittaa siihen, että lapinraunioiden luokse on palattu yhä uudelleen ja uudelleen. Ne ovat ilmeisesti toimineet rituaalisina kiinnekohtina liikkuvaa elämää viettäville yhteisöille. Roomalaiselle rautakaudelle (0-400 jaa.) ajoitetuista lapinraunioista on muualla Suomessa tyypillisesti löydetty metalliesineitä. Tutkimusalueen lapinrauniosta ei ole tehty yhtäkään metalliesinelöytöä. Tämän perusteella on mahdollista, että lapinrauniotradition myöhäisimpiä kehitysvaiheita ei ole alueella koskaan omaksuttu.

Yhteiskuntaluokka ja maku

Thee thesis, which consists of four original articles and a summarizing chapter, discusses homology between social class and cultural taste. Cultural taste is defined as the choices made in different areas of culture (television, cinema, reading, music, visual arts, sports, dining out, and leisure pursuits). Taste choices manifest themselves as likes and dislikes but also in what a person does. Social class is observed through occupational status, level of education, income and subjective views on class. The central research question concerns the relationship between social class and consumption of culture. The study aims to clarify what kind of class related differences can be found in cultural consumption, but also how these differences are connected to other factors stratifying the society such as gender, age and mother tongue. The data that is being analyzed consists of the data gathered by the project Cultural Capital and Social Differentiation in Contemporary Finland: An International Comparison. Class identification and the relation of cultural divisions to the socioeconomic ones are being analyzed using a nationally represent-ative survey data (N = 1388). Individual interviews (N = 25) and twenty focus group interviews (N = 20) on cultural consumption are also being analyzed. The theoretical framework is built around Pierre Buourdieu s theory of distinction and its critique but also recent research that expands on bourdieusian theory. In the theory of distinction lifestyle is thought to be defined through the quantity and quality of different capitals (economic, cultural and social). Cultural tastes are therefore linked to class status through different capitals. The study shows that the majority of Finns can place themselves in the class scene. Moreover, class-related differences can be found in cultural consumption in empirical analyses. The main differences between classes can be seen in how different classes relate to cultural products but also in the number of leisure pursuits. Being well-off economically is connected to being well-off culturally. High status manifests as omnivorous cultural consumption. The central differences are built upon occupational class so that the working class is more passive than other class groups. Same difference can be found in relation to education and income level. Other im-portant divisive variable is age. Age group defines what is being consumed: the younger respondents are inclined to choose popular culture whereas the older age groups choices represent more traditional taste choices.

Microfinance, Efficiency and Agricultural Production in Bangladesh

The objectives of this study were to make a detailed and systematic empirical analysis of microfinance borrowers and non-borrowers in Bangladesh and also examine how efficiency measures are influenced by the access to agricultural microfinance. In the empirical analysis, this study used both parametric and non-parametric frontier approaches to investigate differences in efficiency estimates between microfinance borrowers and non-borrowers. This thesis, based on five articles, applied data obtained from a survey of 360 farm households from north-central and north-western regions in Bangladesh. The methods used in this investigation involve stochastic frontier (SFA) and data envelopment analysis (DEA) in addition to sample selectivity and limited dependent variable models. In article I, technical efficiency (TE) estimation and identification of its determinants were performed by applying an extended Cobb-Douglas stochastic frontier production function. The results show that farm households had a mean TE of 83% with lower TE scores for the non-borrowers of agricultural microfinance. Addressing institutional policies regarding the consolidation of individual plots into farm units, ensuring access to microfinance, extension education for the farmers with longer farming experience are suggested to improve the TE of the farmers. In article II, the objective was to assess the effects of access to microfinance on household production and cost efficiency (CE) and to determine the efficiency differences between the microfinance participating and non-participating farms. In addition, a non-discretionary DEA model was applied to capture directly the influence of microfinance on farm households production and CE. The results suggested that under both pooled DEA models and non-discretionary DEA models, farmers with access to microfinance were significantly more efficient than their non-borrowing counterparts. Results also revealed that land fragmentation, family size, household wealth, on farm-training and off farm income share are the main determinants of inefficiency after effectively correcting for sample selection bias. In article III, the TE of traditional variety (TV) and high-yielding-variety (HYV) rice producers were estimated in addition to investigating the determinants of adoption rate of HYV rice. Furthermore, the role of TE as a potential determinant to explain the differences of adoption rate of HYV rice among the farmers was assessed. The results indicated that in spite of its much higher yield potential, HYV rice production was associated with lower TE and had a greater variability in yield. It was also found that TE had a significant positive influence on the adoption rates of HYV rice. In article IV, we estimated profit efficiency (PE) and profit-loss between microfinance borrowers and non-borrowers by a sample selection framework, which provided a general framework for testing and taking into account the sample selection in the stochastic (profit) frontier function analysis. After effectively correcting for selectivity bias, the mean PE of the microfinance borrowers and non-borrowers were estimated at 68% and 52% respectively. This suggested that a considerable share of profits were lost due to profit inefficiencies in rice production. The results also demonstrated that access to microfinance contributes significantly to increasing PE and reducing profit-loss per hectare land. In article V, the effects of credit constraints on TE, allocative efficiency (AE) and CE were assessed while adequately controlling for sample selection bias. The confidence intervals were determined by the bootstrap method for both samples. The results indicated that differences in average efficiency scores of credit constrained and unconstrained farms were not statistically significant although the average efficiencies tended to be higher in the group of unconstrained farms. After effectively correcting for selectivity bias, household experience, number of dependents, off-farm income, farm size, access to on farm training and yearly savings were found to be the main determinants of inefficiencies. In general, the results of the study revealed the existence substantial technical, allocative, economic inefficiencies and also considerable profit inefficiencies. The results of the study suggested the need to streamline agricultural microfinance by the microfinance institutions (MFIs), donor agencies and government at all tiers. Moreover, formulating policies that ensure greater access to agricultural microfinance to the smallholder farmers on a sustainable basis in the study areas to enhance productivity and efficiency has been recommended. Key Words: Technical, allocative, economic efficiency, DEA, Non-discretionary DEA, selection bias, bootstrapping, microfinance, Bangladesh.

Early Growth and Later Health, Focus on Metabolic Syndrome, Obesity and Physical Activity

The Developmental Origins of Health and Disease Hypothesis proposes that adverse health outcomes in adult life are in part programmed during fetal life and infancy. This means that e.g. restricted nutrition during pregnancy programmes the offspring to store fat more effectively, to develop faster and to reach puberty earlier. These adaptations are beneficial in terms of short term survival. However, in developed countries these adaptations often lead to an increased risk of obesity and metabolic disturbances in later life, due to a mismatch between the prenatal and postnatal environment. This thesis aimed to study the role of early growth in people who are obese as adults, but metabolically healthy as well as in those who are normal in weight but metabolically obese. Other study aims were to assess whether physical activity and cardiorespiratory fitness are programmed early in life. The role of socioeconomic status in the development of obesity from a life course setting was also studied. These studies included 2003 men and women born in Helsinki between 1934 and 1944 with detailed information of their prenatal and childhood growth as well as living conditions. They participated in the detailed clinical examination during the years 2001-2004. A sub-group of the subjects participated in the UKK Institute 2-kilometre walk test. Metabolic syndrome was defined according to the 2005 criteria of the International Diabetes Federation. Among the obese men and women 20 % were metabolically healthy. Those with metabolic syndrome did not differ in birth size compared to the healthy ones, but by two years of age, they were lighter and thinner, and remained so up to 11 years. The period when changes in BMIs were predictive of the metabolic syndrome was from birth to 7 years. Of the normal weight individuals 17 % were metabolically obese. Again, there were no differences in birth size. However, by the age 7 years, those men who later developed metabolic syndrome were thinner. Gains in BMI during the first two years of life were protective of the syndrome. Children who were heavier, and especially taller, were more physically active, exercised with higher intensity and had higher cardiorespiratory fitness in their adult life than those who were shorter and thinner as children. Lower educational attainment and lower adult social class were associated with obesity in both men and women. Childhood social class was inversely associated with body mass index only in men while lower household income was associated with higher BMI in women. These results support the role of early life factors in the development of metabolic syndrome and adult life style. Early detection of risk factors predisposing to these conditions is highly relevant from a public health point of view.

Molecular profiling of indoor microbial communities in moisture damaged and non-damaged buildings

Epidemiological studies have shown an elevation in the incidence of asthma, allergic symptoms and respiratory infections among people living or working in buildings with moisture and mould problems. Microbial growth is suspected to have a key role, since the severity of microbial contamination and symptoms show a positive correlation, while the removal of contaminated materials relieves the symptoms. However, the cause-and-effect relationship has not been well established and knowledge of the causative agents is incomplete. The present consensus of indoor microbes relies on culture-based methods. Microbial cultivation and identification is known to provide qualitatively and quantitatively biased results, which is suspected to be one of the reasons behind the often inconsistent findings between objectively measured microbiological attributes and health. In the present study the indoor microbial communities were assessed using culture-independent, DNA based methods. Fungal and bacterial diversity was determined by amplifying and sequencing the nucITS- and16S-gene regions, correspondingly. In addition, the cell equivalent numbers of 69 mould species or groups were determined by quantitative PCR (qPCR). The results from molecular analyses were compared with results obtained using traditional plate cultivation for fungi. Using DNA-based tools, the indoor microbial diversity was found to be consistently higher and taxonomically wider than viable diversity. The dominant sequence types of fungi, and also of bacteria were mainly affiliated with well-known microbial species. However, in each building they were accompanied by various rare, uncultivable and unknown species. In both moisture-damaged and undamaged buildings the dominant fungal sequence phylotypes were affiliated with the classes Dothideomycetes (mould-like filamentous ascomycetes); Agaricomycetes (mushroom- and polypore-like filamentous basidiomycetes); Urediniomycetes (rust-like basidiomycetes); Tremellomycetes and the family Malasseziales (both yeast-like basidiomycetes). The most probable source for the majority of fungal types was the outdoor environment. In contrast, the dominant bacterial phylotypes in both damaged and undamaged buildings were affiliated with human-associated members within the phyla Actinobacteria and Firmicutes. Indications of elevated fungal diversity within potentially moisture-damage-associated fungal groups were recorded in two of the damaged buildings, while one of the buildings was characterized by an abundance of members of the Penicillium chrysogenum and P. commune species complexes. However, due to the small sample number and strong normal variation firm conclusions concerning the effect of moisture damage on the species diversity could not be made. The fungal communities in dust samples showed seasonal variation, which reflected the seasonal fluctuation of outdoor fungi. Seasonal variation of bacterial communities was less clear but to some extent attributable to the outdoor sources as well. The comparison of methods showed that clone library sequencing was a feasible method for describing the total microbial diversity, indicated a moderate quantitative correlation between sequencing and qPCR results and confirmed that culture based methods give both a qualitative and quantitative underestimate of microbial diversity in the indoor environment. However, certain important indoor fungi such as Penicillium spp. were clearly underrepresented in the sequence material, probably due to their physiological and genetic properties. Species specific qPCR was a more efficient and sensitive method for detecting and quantitating individual species than sequencing, but in order to exploit the full advantage of the method in building investigations more information is needed about the microbial species growing on damaged materials. In the present study, a new method was also developed for enhanced screening of the marker gene clone libraries. The suitability of the screening method to different kinds of microbial environments including biowaste compost material and indoor settled dusts was evaluated. The usability was found to be restricted to environments that support the growth and subsequent dominance of a small number microbial species, such as compost material.

Sika- ja siipikarjatalouden rakennemuutoskorvaus C-tukialueella

Sika- ja siipikarjatilojen määrä Suomessa on vähentynyt koko EU-jäsenyyden ajan tuotannon keskittyessä yhä suurempiin yksiköihin. Tuotantomäärät ovat kasvaneet, mutta viljelijöiden tulotaso on alentunut, joten maatalouden ulkopuoliset ammatit houkuttelevat luopumaan eläinten pidosta tai maataloudesta kokonaan. Sika- ja siipikarjatalouden rakennemuutoksen taloudellisena kannustimena otettiin vuonna 2009 käyttöön sika- ja siipikarjatalouden rakennemuutoskorvaus, jota maksetaan kompensaationa sika- ja siipikarjataloudesta luopuville viljelijöille. Tämän työn tarkastelukohteena on rakennemuutoskorvaus C-tukialueella, jossa yksinään on lähes yhtä paljon sika- ja siipikarjatiloja kuin A- ja B-alueilla yhteensä. Tutkimuksen tavoitteena on selvittää, millaiset sika- ja siipikarjatilat sekä koko C-alueella että C-alueen eri osissa ovat hakeneet rakennemuutoskorvausta ja miten tilat ovat alueellisesti sijoittuneet. Maatalouden rakennepolitiikalla pyritään vaikuttamaan maatalouden yhteiskunnalliseen rakenteeseen. Rakennepoliittisilla toimilla pyritään vähentämään viljelijöiden ja tilojen määrää, jolloin maataloustulo jakaantuu pienemmälle viljelijämäärälle taaten heille suuremmat tulot. Maatalouden rakennemuutosta tapahtuu, kun maatalouden rakenteessa tapahtuu tietyllä aikavälillä muutos. Rakennemuutoksessa ja -kehityksessä on alueellisia eroja. Aluetaloustiede pyrkii selittämään, mistä alueelliset erot johtuvat ja miksi alueet erilaistuvat. Suomessa eri maakunnilla on eroja ja omia alueellisia ominaispiirteitään, joilla on suuri merkitys alueen työllisyyteen ja väestön sijoittumiseen alueella. Eri maakunnissa työllisyystilanne on vaihteleva, mutta joka maakunnassa on kuitenkin työvoimapulaa useissa sellaisissa ammateissa, joihin eläinten tai tilan pidon lopettavien viljelijöiden olisi mahdollista työllistyä. Sika- ja siipikarjatalouden rakennemuutoskorvaus on kansallinen kotieläintuki, jota maksetaan tilakohtaisen viitemäärän perusteella tiloille, jotka ovat juuri lopettaneet sika- ja siipikarjatuotantonsa tai aikovat sen lopettaa. Korvausta on voitu maksaa tukiehdot täyttävälle tuenhakijalle joko vuosina 2009–2010 tai vuosina 2010–2011 ja sen maksimimäärä on tilaa kohden enintään 20000 euroa vuodessa. Kahden korvausvuoden jälkeen tilan viitemäärä lakkautetaan ja sen jälkeen tilalle ei enää makseta sika- ja siipikarjatalouden tukia. Tilan on kuitenkin edelleen mahdollista jatkaa sika- ja siipikarjatuotantoaan markkinaehtoisena. Tutkimuksen aineisto on 389 tilan tiedot sisältävä Tiken raportti tukityypin 1612 (sika- ja siipikarjatalouden rakennemuutoskorvaus, pohjoinen) tukihakutiedoista vuodelta 2010. Tutkimusote oli kvantitatiivinen ja koska havaintoaineisto kattaa kaikki C-alueen korvauksenhakijat, tehtiin tutkimus kokonaistutkimuksena. Tutkimustulosten mukaan 63 % korvausta hakeneista tiloista sijoittuu C1-alueelle ja 54 % Etelä-Pohjanmaalle ja Pohjanmaalle. Kuntatasolla eniten rakennemuutoskorvaustiloja oli Närpiössä. C-alueella tuenhakijat olivat iältään 20–71-vuotiaita. Hakijoista 62 % harjoitti päätuotantosuuntanaan viljanviljelyä ja peltoalaa kaikilla hakijoilla oli hallinnassaan lähes 16000 ha. Rakennemuutoskorvausta maksettiin C-alueella yhteensä yli 2,3 miljoonaa euroa. Kun rakennemuutoskorvauksen viitemäärät kahden korvausvuoden jälkeen lakkautetaan, poistuu tuo-tannosta yli 9600 ey. Sekä C-alueella että kaikki ELY-keskukset huomioiden oli korvauksenhakijoita kaikkia ikäluokkia tarkasteltaessa eniten 50–59-vuotiaissa. Eniten hakijoita oli viitemääräluokassa 10,01–20 ey ja viljelyalaluokassa 25,01–40 ha, vähiten luokissa 40,01–50 ey ja 50,01 ey tai enemmän sekä 150,01 ha tai enemmän. Yleisin maksuluokka oli 3000,01–4500 euroa, harvinaisin 15000,01–20000 euroa. Rakennemuutoskorvauksella saavutettuja hyötyjä ja kustannuksia on toistaiseksi vaikea määritellä, koska vuoden 2011 maksatus on vielä kesken.

Jatrophanviljely ja maankäyttö Vietnamissa

Biofuels are under discussion all over the world today. There are fears that the farming of biofuel plants hurts food production and weakens the food security of the poor. On the other hand, biofuel production could lessen the green house gas emissions caused by transportation, and it could also spread the profits from fuel markets more evenly between countries. The aim of this thesis is to find out how an oil plant called jatropha curcas L., which is used for biodiesel production, can affect the sustainability of livelihoods in Vietnam from the point of view of land use. Special attention is given to the effects of jatropha farming on food production, land productivity, natural resources of livelihoods and global livelihood. Jatropha belongs to the family Euphorbiaceae, and it grows naturally in tropical and subtropical areas. It can be grown on poor soils, its seeds have high oil content, and it cannot be eaten due to its toxicity. The plant grows naturally in Vietnam, and during the past few years it has also begun to be farmed for making biodiesel. Population growth in Vietnam has slowed down, but the population's standard of living and energy consumption are still rising quickly. An interest in the international biodiesel markets has awoken following Vietnam's opening up to international trade. Jatropha diesel plays a significant part in Vietnam’s clean fuel strategy, and many companies have set up jatropha plantations to produce raw material for biodiesel. Diesel made from jatropha is planned to be used both locally and for export. This thesis uses a theoretical concept of sustainable livelihoods. According to the theory, the resources that people have shape their livelihood possibilities. Farming of jatropha affects the livelihoods of people especially through land use, as land use changes have effects on many of the livelihood resources. In addition to the written sources, the material of the thesis is based on 14 interviews in Vietnam and Finland, and on observation during a field trip to Northern Vietnam in the spring of 2008. The results of the thesis show that jatropha diesel can support the sustainability of livelihoods at different scales if it is produced with deliberation. However, positive results are only possible if decisions are made carefully and more experience is collected. The possibilities of sustainable jatropha farming depend mainly on the previous land use methods and ways of production. Farming of jatropha does not threaten food production in Vietnam if the farming plans are implemented as planned. Jatropha may take some land from cassava, but at the same time, food production can be increased if mixed farming is used on some farms. Plenty of new research information and practical experiences on jatropha farming has to be collected before results of the real sustainability of the farming are ready. Carefully considered continuation and documentation of present and future projects would help to understand the possibilities of jatropha diesel in Vietnam and elsewhere.

Krapula kuuluu kuvaan. Yhdeksäsluokkalaisten käsitykset alkoholinkäytön riskeistä eri juomistilanteissa.

Tutkimuksessa tarkastellaan yhdeksäsluokkalaisten käsityksiä alkoholinkäyttöön liittyvistä riskeistä. Erityisesti keskitytään riskikäsitysten tilannesidonnaisuuteen suhteuttamalla nuorten riskikäsitykset erilaisiin juomistilanteisiin ja tilanteiden sosiaalisiin konteksteihin. Laadullista tutkimusta nuorten alkoholinkäytöstä on tehty viime aikoina kovin vähän, mutta yleinen mielikuva nuorten humalahakuisesta juomisesta pitää pintansa. Nuorten käsitykset alkoholinkäytön riskeistä antavat viitteitä nuorten alkoholiasenteista, minkä voidaan olettaa vaikuttavan itse alkoholinkäyttöön. Tutkimusaineistona on virikkeellinen ryhmähaastatteluaineisto (RAGI), joka on kerätty vuosien 2010 ja 2011 vaihteessa helsinkiläisissä peruskouluissa yhteistyössä ”Nuorten alkoholimielikuvat – suomalais-italialainen ja alueellinen vertailu” -tutkimusprojektin kanssa. Aineisto koostuu nuorten keskinäisistä keskusteluista, joissa keskustelun virikkeinä on käytetty lyhyitä elokuvakatkelmia. Keskusteluaineistosta erotetaan lähempään tarkasteluun nuorten tuottama riskipuhe. Riskin käsitteellä tarkoitetaan tässä tutkimuksessa uhan, vaaran tai ikävän seurauksen mahdollisuutta. Analyysin lähtökohtana ovat erilaiset juomistilanteet, joiden vertailukohtana käytetään Jukka Törrösen ja Antti Maunun luomaa juomistilanteiden lajityyppijaottelua. Elokuvakatkelmat, nuorten tulkinnat erilaisista juomistilanteista ja riskikäsitykset suhteutetaan lajityyppijaotteluun. Pääasiassa huomio keskittyy juomistilanteiden tilannetekijöistä sosiaaliseen kontekstiin. Nuorten voidaan todeta muodostavan käsityksensä alkoholinkäyttöön liittyvistä riskeistä tilannesidonnaisesti. Juomistilanteen sosiaalinen konteksti vaikuttaa siihen, miten riskialtista nuoret ajattelevat alkoholinkäytön olevan kussakin juomistilanteessa. Aikuisten ja nuorten tulkinnat juomistilanteista poikkeavat toisistaan esimerkiksi siten, että nuoret mieltävät usein myös ei-humalahakuiset juomistilanteet mahdollisesti humalahakuisiksi. Nuorilla kuitenkin on monia käsityksiä erilaisista juomistilanteista. Nuoret myös tekevät selvästi eron nuorille hyväksytyn ja aikuisille soveltuvan alkoholinkäytön välille. Bilettämistä pidetään sopivana alkoholinkäyttötapana nuorille, mutta yksin juomista taas ei ja aikuisten kohdalla nuoret ajattelevat sopivan ja ei-sopivan alkoholinkäyttötyylin olevan päinvastoin. Kaikkiin alkoholinkäytön ikäviin seurauksiin nuoret eivät suhtaudu riskeinä, vaan esimerkiksi krapulan ja pahoinvoinnin katsotaan kuuluvan osana nuorten alkoholinkäyttöä. Toisaalta nuoret mieltävät alkoholinkäyttöön liittyvän myös hyvin vakavia riskejä kuten hukkuminen ja seksuaalinen hyväksikäyttö. Huoli nuorten myönteisistä alkoholiasenteista tuntuu olevan aiheellinen, mutta nuorten käsitykset alkoholinkäytöstä ja siihen liittyvistä riskeistä eivät rajaudu humalahakuiseen juomiseen.
