Environmental change and human history in the Jabal Harun area, Jordan

The research is related to the Finnish Jabal Harun Project (FJHP), which is part of the research unit directed by Professor Jaakko Frösén. The project consists of two interrelated parts: the excavation of a Byzantine monastery/pilgrimage centre on Jabal Harun, and a multiperiod archaeological survey of the surrounding landscape. It is generally held that the Near Eastern landscape has been modified by millennia of human habitation and activity. Past climatic changes and human activities could be expected to have significantly changed also the landscape of the Jabal Harun area. Therefore it was considered that a study of erosion in the Jabal Harun area could shed light on the environmental and human history of the area. It was hoped that it would be possible to connect the results of the sedimentological studies either to wider climatic changes in the Near East, or to archaeologically observable periods of human activity and land use. As evidence of some archaeological periods is completely missing from the Jabal Harun area, it was also of interest whether catastrophic erosion or unfavourable environmental change, caused either by natural forces or by human agency, could explain the gaps in the archaeological record. Changes in climate and/or land-use were expected to be reflected in the sedimentary record. The field research, carried out as part of the FJHP survey fieldwork, included the mapping of wadi terraces and cleaning of sediment profiles which were recorded and sampled for laboratory analyses of facies and lithology. To obtain a chronology for the sedimentation and erosion phases also OSL (optically stimulated luminescence) dating samples were collected. The results were compared to the record of the Near Eastern palaeoclimate, and to data from geoarchaeological studies in central and southern Jordan. The picture of the environmental development was then compared to the human history in the area, based on archaeological evidence from the FJHP survey and the published archaeological research in the Petra region, and the question of the relationship between human activity and environmental change was critically discussed. Using the palaeoclimatic data and the results from geoarchaeological studies it was possible to outline the environmental development in the Jabal Harun area from the Pleistocene to the present.It is appears that there was a phase of accumulation of sediment before the Middle Palaeolithic period, possibly related to tectonic movement. This phase was later followed by erosion, tentatively suggested to have taken place during the Upper Palaeolithic. A period of wadi aggradation probably occurred during the Late Glacial and continued until the end of the Pleistocene, followed by significant channel degradation, attributed to increased rainfall during the Early Holocene. It seems that during the later Holocene channel incision has been dominant in the Jabal Harûn area although there have been also small-scale channel aggradation phases, two of which were OSL-dated to around 4000-3000 BP and 2400-2000 BP. As there is no evidence of tectonic movements in the Jabal Harun area after the early Pleistocene, it is suggested that climate change and human activity have been the major causes of environmental change in the area. At a brief glance it seems that many of the changes in the settlement and land use in the Jabal Harun area can be explained by climatic and environmental conditions. However, the responses of human societies to environmental change are dependent on many factors. Therefore an evaluation of the significance of environmental, cultural, socio-economic and political factors is needed to decide whether certain phenomena are environmentally induced. Comparison with the wider Petra region is also needed to judge whether the phenomena are characteristic of the Jabal Harun area only, or can they be connected to social, political and economic development over a wider area.

Virolaisiin naistenlehtiin kirjoittuva materialistinen maailma : Annen, Eesti Naisen ja Stiilin kansijuttujen tarkastelua kriittisen tekstintutkimuksen menetelmällä

Pro gradu -tutkielmassani tarkastelen Viron kolmen suurimman naistenlehden kansijuttuja systeemis-funktionaalisen kieliopin menetelmällä. Lehdet ovat Anne, Eesti Naine ja Stiil. Aineisto, tammikuussa 2003 ? syyskuussa 2004 ilmestyneet 55 artikkelia, on pääosin haettu lehtien omista internetarkistoista. Tutkin kansijuttuja systeemis-funktionaalisen kieliopin menetelmällä. Tavoitteenani on ollut selvittää, minkälaisia arvoja, asenteita ja maailmankuvia teksteihin kirjoittuu. Lähestyn kansijuttuja ideationaalisen, interpersoonaisen ja tekstuaalisen metafunktion näkökulmista. Kaikki kolme metafunktiota esiintyvät kielellisissä ilmiöissä yhtä aikaa. Mitä tahansa puhuttua tai kirjoitettua lausetta on mahdollista analysoida minkä tahansa metafunktion kannalta. Ideationaalinen metafunktio tarkoittaa yhtäältä sitä, minkälaisena maailma ja ilmiöt teksteissä kuvataan, toisaalta sitä, minkälaisia prosesseja teksteissä representoidaan. Interpersoonainen metafunktio tarkoittaa teksteihin kirjoittuvia suhteita, vuorovaikutusta ja identiteettejä, esimerkiksi toimittajan ja lukijan välistä suhdetta ja heidän roolejaan. Kun tekstiä tutkitaan tekstuaalisen metafunktion kannalta, siitä nostetaan esiin kieliopillisia, sanastollisia ja syntaktisia piirteitä, joista tekstit rakentuvat koherenteiksi kokonaisuuksiksi. Pro graduni kuuluu kriittisen tekstintutkimuksen alaan. Kriittinen tekstintutkimus on monitieteinen menetelmä, jonka tavoitteena on selvittää kielellisesti representoituja valtasuhteita sekä eksplisiittisesti ja implisiittisesti lauseisiin kirjoittuvia arvotuksia. Kriittisen tekstintutkimuksen tavoitteena on osoittaa, millä tavalla ihmisten ajattelua pystytään ohjaamaan ja hallitsemaan kielellisten ratkaisujen keinoin. Viron kolmen suurimman naistenlehden kansijutuille yhteinen piirre on materialistinen maailmankuva, joka ilmenee teksteissä muun muassa korostuneena kulutustottumusten, ulkonäön ja elämäntyylin kuvailuna. Tekstit ovat avoimen kaupallisia. Selkein osoitus kaupallisuudesta on tunnetuttujen vaate-, kosmetiikka ja automerkkien näkyminen teksteissä, luonnollisena osana juttua. Kansijuttujen haastateltavat ovat eri aloja edustavia, korkeasti koulutettuja, itsenäisiä ja näkyvissä asemissa vaikuttavia henkilöitä, valtaosaltaan naisia. Juttuihin he representoituvat perhettä, isänmaata ja uskontoa arvostavina perusarvojen kannattajina, joita esimerkiksi tasa-arvokysymykset, syrjäytyminen tai globalisaatio eivät kiinnosta. Keskeinen kysymys onkin journalistinen prosessi, jonka tuloksena kansijutut ovat syntyneet. Vaikka kansijutuissa näennäisesti äänessä ovat voimakkaat virolaisnaiset, voi rivien välistä ymmärtää, että tarinan kerrontaan vaikuttavat myös julkaisijoiden taloudelliset intressit. Avainsanat: diskurssi, funktionaalisuus, genre, ideologia, kansijuttu, luonnollistuma, media, metafunktio, naistenlehti, tavoite, tekstilaji, tervejärkisyys, valta, virolainen

Ei sanat salahan joua : fennistiikan murteenkeruun historiaa 1868 - 1925

Pro gradu -tutkielmani käsittelee Suomen murteiden sanakirjan taustaksi kerätyn Suomen murteiden sana-arkiston kartuttamisen historiaa; fennistisen murteenkeruun alkuvaiheita. Lähestyn murresanakirjan pitkää hanketta tutkimus- ja kulttuurihistoriallisesta näkökulmasta. Kansankielen sanakirja on fennistiikan merkittävimpiä tutkimushankkeita. Suo-men kielen vanhojen pitäjänmurteiden sanasto on ällistyttävän laaja aineisto, jonka keräämiseen ja julkaisemiseen on kulunut toista vuosisataa, ja sanakirjan toimitustyö jatkuu edelleen. Kansanmurteemme sisältävät paitsi kielitieteellisesti mielenkiintoista aineistoa myöskin runsaasti tietoa agraarisen elinkeinorakenteen aikakaudelta. Dialektologia ja kansatiede kulkevat käsikkäin. Murresanakirja on niin ollen merkittävä kansallinen omaisuus, jonka arvo koko suomalaiselle yhteiskunnalle on eittämättä suuri. Murteiden sanakirjan syntysanat on ajoitettavissa vuoteen 1868, vaikka toki fennistiikassa oli leksikografisia pyrintöjä jo ennen sitä (mm. Lönnrotin Suomalais-ruotsalainen sanakirja). Sanakirjahankkeessa on hahmotettavissa kolme vaihetta, joita kutsun ryhdistäytymisiksi. Nämä tapahtuivat noin vuosina 1896, 1916 ja 1925. Valotan työni aluksi hieman kansallisten tieteiden ja 1800-luvun alun aatehistoriallista taustaa (luku 2), jonka jälkeen tutkin murresanakirjahankkeen alkuvaiheita ja ensimmäisten sanastonkeruiden käynnistymistä (luku 3). Käsittelen kutakin hankkeen organisatorista muutosvaihetta ja hallinnollisten puitteiden kehittymistä luvuissa 4-6. Lopuksi pohdin murresanakirjan ja murteenkeruun historiallista merkitystä fennistiikalle ja yhteiskunnalle (luku 7). Tutkimukseni lähteinä on oppihistoriallista kirjallisuutta sekä murteiden keruusta vastanneiden yhteisöjen asiakirjoja. Erityisen kiinnostaviksi osoittautuivat Kotimaisten kielten tutkimuskeskuksessa säilytettävät sanakirjahankkeen hallinnolliset asiakirjat 1916-1925. Tuon esiin varhaisempiakin pöytäkirjamainintoja. Hankkeen alussa Suomalaisen Kirjallisuuden Seuran Kielitieteellinen Osakunta ja Kotikielen Seura keräsivät ensimmäisiä sanastokokoelmia. Tämän jälkeen ensimmäinen ryhdistäytyminen tapahtui vuodesta 1896 lähtien, jolloin Suomalaisen Kirjallisuuden Seura otti vastuun hankkeesta, E. N. Setälän tunnettua sanakirjaohjelmaa ja E. A. Ekmanin Suomen kielen keräilysanastoa noudattaen. Keruu oli kuitenkin liian hidasta, joten 1916 perustettiin Suomen kielen sanakirjaosakeyhtiö, jotta toimintaan saataisiin enemmän varoja. Ensimmäinen maailmansota ja sisällissota kuitenkin romahduttivat rahan arvon, ja kolmannen kerran hanke jouduttiin organisoimaan uudelleen vuonna 1925, Sanakirjasäätiön muodossa. Vuonna 1976 Sanakirjasäätiö liittyi Kotimaisten kielten tutkimuskeskukseen. Kansanmurteiden keräämisessä korostuu kaikissa keruun vaiheissa kaksi asiaa. Ensinnäkin sanastuksella oli aina kiire. Vanhat murteet olivat katoamassa, ja ne piti saada nopeasti talteen. Tähän kiinnitettiin huomiota jo varhain, ja vielä 1900-luvun loppupuoliskollakin, kun keruuhanke hiljalleen saatiin loppuunviedyksi. Toiseksi sanakirjahanke on aina joutunut elämään kädestä suuhun, toisin sanoen taloudelliset puitteet ovat sanelleet keruumahdollisuudet. Vakaalle taloudelliselle pohjalle hanke pääsi vasta 1930-luvulla Sanakirjasäätiön aikana, jolloin siihen alettiin saada valtion rahoitusta. Murresanakirjahankkeen läpi kulkee punaisena lankana kansallisromanttinen innostus ja isänmaallis-tieteellinen pyrkimys suomen kirjakielen kehittämiseen, joka vielä 1800-luvun puolivälissä oli meneillään. Kansalliset tieteet lujittivat itsenäistymistä ja suoma-laistumista. Aatehistorian kautta sanakirjahanke asettuu laajempaan yhteyteen.

Montessorivälineet esiopetuksessa : Montessoriohjaajakoulutuksen saaneiden lastentarhanopettajien käsityksiä montessorivälineiden soveltuvuudesta esiopetuksessa

Tutkimuksessa selvitettiin montessorivälineiden soveltuvuutta suomalaiseen esiopetukseen montessoriohjaajakoulutuksen saaneiden lastentarhanopettajien arvioimina. Tutkimuksen ensimmäisenä tehtävänä oli selvittää, missä määrin montessorivälineitä käytettiin esiopetuksessa. Tutkimuksessa kartoitettiin montessorivälineiden osuutta vastaajien lapsiryhmien toimintamateriaaleista sekä mahdollisia esteitä niiden määrän lisäämiselle. Samoin selvitettiin, kuinka tärkeäksi montessorivälineiden merkitys koettiin opetussuunnitelman tavoitteiden toteutumisessa. Lisäksi kartoitettiin montessorivälineiden käytön laajuutta vastaajien työyhteisössä sekä mahdollisia esteitä välineiden laajemmalle käytölle. Tutkimuksen toisena tehtävänä oli selvittää, miten montessorivälineet tukevat lapsikeskeiselle esiopetukselle asetettuja tavoitteita yksilöllisyyden, sosiaalisten taitojen kehittymisen, omatoimisuuden ja aktiivisuuden, leikin merkityksen sekä välineistön monipuolisuuden suhteen. Tutkimuksen kohderyhmäksi valittiin mahdollisimman kattavasti ne montessoriohjaajat, jotka olivat saaneet myös lastentarhanopettajakoulutuksen. Kohderyhmä käsitti 74 henkilöä. Tutkimus suoritettiin postikyselynä joulukuussa 1996 ja tammikuussa 1997. Tutkimuksen vastausprosentiksi muodostui 79,3 %. Tutkimuksen tulokset osoittivat, että montessorivälineiden osuus vastaajien lapsiryhmien käytössä olevista toimintamateriaaleista oli merkittävä. Tämä korostui erityisesti montessoripäiväkodeissa, -leikkikouluissa ja päiväkodin montessoriryhmissä. Kaikissa toimipaikoissa montessorivälineitä ei ollut riittävästi, vaikka kiinnostus niitä kohtaan oli suuri. Montessorivälineiden osuuden lisäämistä vaikeuttivat mm. taloudelliset esteet. Montessorivälineiden merkitys opetussuunnitelman tavoitteiden toteutumisenkannalta osoittautui tärkeäksi. Tulosten perusteella suppeammallakin montessorivälinemäärällä oli opetussuunnitelman tavoitteiden kannalta suuri merkitys. Montessorivälineiden käytön laajuus vastaajientyöyhteisössä vaihteli toimipaikoittain. Koulutuksen puute ilmeni merkittävimmäksi esteeksi montessorivälineiden laajemmalle käytölle vastaajien työyhteisössä. Tutkimuksen tulosten perusteella montessorivälineillä työskentely tukee vahvasti lapsikeskeisen esiopetuksen kannalta tärkeitä tavoitteita yksilöllisyyden, omatoimisuuden ja aktiivisuuden sekä sosiaalisten taitojen kehittymisen suhteen. Montessorivälineiden katsottiin soveltuvan hyvin esiopetukseen myös monipuolisuutensa ansiosta. Leikin merkitys ei montessorivälineillä työskentelyssä ollut keskeisessä asemassa. Sen sijaan montessorivälineillä työskentelyssä painottuivat leikki, työ ja oppiminen.

Predictors of disability retirement: From early intentions to retirement

The strong tendency of elderly employees to retire early and the simultaneous aging of the population have been major topics of policy and scientific debate. A key concern has been the financing of future pension schemes and possible labour shortage, especially in social and health services within the public sector. The aging of the population is inevitable, but efforts can be made to prevent or postpone early exit from the labour force, e.g., by identifying and intervening in the factors that contribute to the process of early retirement due to disability. The associations of intentions to retire early, poor mental health and different psychosocial factors with the process of disability retirement are still poorly understood. The purpose of this study was to investigate the associations of intentions to retire early, poor mental health, work and family related psychosocial factors and experiences of earlier life stages with the process of disability retirement. The data were derived from the Helsinki Health Study (HHS, N=8960) and the Health and Social Support Study (HeSSup, N=25 901). The Helsinki Health Study is an ongoing employee cohort study among middle-aged women and men. The Health and Social Support Study is an ongoing longitudinal study of a working-age sample representative of the Finnish population. The analyses were restricted to respondents 40 years of age or older. Age and gender adjusted prevalence and incidence rates were calculated. Associations were studied by using logistic, multinomial and Cox regression. Strong intentions to retire early were common among employees. Poor mental health, unfavourable working conditions and work-to-family conflicts were clearly associated with increased intentions to retire early. Strong intentions to retire early predicted disability retirement. Risk of disability retirement increased in a dose-response manner with increasing number of childhood adversities. Poor mental and somatic health, life dissatisfaction, heavy alcohol consumption, current smoking, obesity and low socioeconomic status were also predictors of disability retirement. The impact of poor mental health and adverse experiences from earlier life stages, work and family related psychosocial factors, e.g., work-family interface, the subjective experience of well-being and health related risk behaviours on the process of disability retirement should be recognised. Preventive measures against disability retirement should be launched before subjective experience of ill health, work disability and strong intentions to retire early emerge.

Sopimusohjaus ohjausmenettelynä sairaanhoitopiirin ja terveyskeskusten yksiköissä ja niiden lääkärien työssä

This study concerns the implementation of steering by contracting in health care units and in the work of the doctors employed by them. The study analyses how contracting as a process is being implemented in hospital district units, health centres and in the work of their doctors, as well as how these units carry out their operations and patient care within the restrictions set by the contracts. Based on interviews with doctors, the study analyses the realisation of operations within the units from the doctors perspective and through their work. The key result of the study is that the steering impact of contracting was not felt at the level of practical work. The contracting was implemented by assigning the related tasks to management only. The management implemented the contract by managing their resources rather than by intervening in doctors activities or the content of their tasks. The steering did not extend to improving practical care processes. This allowed the unchanged continuation of core operations in an autonomous manner and in part, protected from the impacts of contracting. In health centres, the contract concluded was viewed as merely steering the operations of the hospital district and its implementation did not receive the support of the centres. The fact that primary health care and specialised health care constitute separate contracting parties had adverse effects on the contract s implementation and the integration of care. A theoretical review unveiled several reasons for the failure of steering by contracting to alter operations within units. These included the perception steering by contracting as a weak change incentive. The doctors shunned the introduction of an economic logic and ideology into health care and viewed steering by contracting as a hindrance to delivering care to patients and a disturbance to their work and patient relationships. Contracting caused tensions between representatives of the financial administration and health care professionals. It also caused internal tensions, while it had varying impacts on different specialities, including the introduction of varying potential to influence contracts. Most factors preventing the realisation of the steering objective could have been ameliorated through positive leadership. There is a need to bridge the gap between financial steering and patient work. Key measures include encouraging the commitment of middle management, supporting leadership expertise and identifying the right methods of contributing to a mutual understanding between the cultures of financing, administration and health care. Criticism of the purchasers expertise and the view that undersized orders are due to the purchaser s financial difficulties underlines the importance of the purchaser s size. Overly detailed, product-based contracts seemed to place the focus on the quantities and costs of services rather than health impacts and efficiency of operations. Bundling contracts into larger service packages would encourage the enhancement of operations. Steering by contracting represents unexploited potential: it could function as a forum for integrated regional planning of services, and the prioritisation and integration of care, and offer an opportunity and an incentive for developing core operations.

Trust, participation and health among ageing people : A cross-sectional cohort study of men and women born in 1926-30, 1936-40, and 1946-50 in the Lahti region, southern Finland

The purpose of the present study was to explore the associations between good self-rated health and economic and social factors in different regions among ageing people in the Päijät-Häme region in southern Finland. The data of this study were collected in 2002 as part of the research and development project Ikihyvä 2002 2012 (Good Ageing in Lahti region GOAL project). The baseline data set consisted of 2,815 participants born in 1926 30, 1936 40, and 1946 50. The response rate was 66 %. According to the previous studies, trust in other people and social participation as the main aspects of social capital are associated with self-rated health. In addition, socioeconomic position (SEP) and self-rated health are associated, but all SEP indicators do not have identical associations with health. However, there is a lack of knowledge of the health associations and regional differences with these factors, especially among ageing people. Regarding these questions, the present study gives new information. According to the results of this study, self-perceived adequacy of income was significantly associated with good self-rated health, especially in the urban areas. Similar associations were found in the rural areas, though education was also considered an important factor. Adequacy of income was an even stronger predictor of good health than the actual income. Women had better self-rated health than men only in the urban areas. The youngest respondents had quite equally better self-rated health than the others. Social participation and access to help when needed were associated with good self-rated health, especially in the urban area and the sparsely populated rural areas. The result was comparable in the rural population centres. The correlation of trust with self-rated health was significant in the urban area. High social capital was associated with good self-rated health in the urban area. The association was quite similar in the other areas, though it was statistically insignificant. High social capital consisted of co-existent high social participation and high trust. The association of traditionalism (low participation and high trust) with self-rated health was also substantial in the urban area. The associations of self-rated health with low social capital (low participation and low trust) and the miniaturisation of community (high participation and low trust) were less significant. From the forms of single participation, going to art exhibitions, theatre, movies, and concerts among women, and studying and self-development among men were positively related to self-rated health. Unexpectedly, among women, active participation in religious events and voluntary work was negatively associated with self-rated health. This may indicate a coping method with ill-health. As a whole, only minor variations in self-rated health were found between the areas. However, the significance of the factors associated with self-rated health varied according to the areas. Economic factors, especially self-perceived adequacy of income was strongly associated with good self-rated health. Also when adjusting for economic and several other background factors social factors (particularly high social capital, social participation, and access to help when needed) were associated with self-rated health. Thus, economic and social factors have a significant relation with the health of the ageing, and improving these factors may have favourable effects on health among ageing people.

Multiple socioeconomic circumstances and health : associations and explanations among Finnish and British public sector employees

Socioeconomic health inequalities have been widely documented, with a lower social position being associated with poorer physical and general health and higher mortality. For mental health the results have been more varied. However, the mechanisms by which the various dimensions of socioeconomic circumstances are associated with different domains of health are not yet fully understood. This is related to a lack of studies tackling the interrelations and pathways between multiple dimensions of socioeconomic circumstances and domains of health. In particular, evidence from comparative studies of populations from different national contexts that consider the complexity of the causes of socioeconomic health inequalities is needed. The aim of this study was to examine the associations of multiple socioeconomic circumstances with physical and mental health, more specifically physical functioning and common mental disorders. This was done in a comparative setting of two cohorts of white-collar public sector employees, one from Finland and one from Britain. The study also sought to find explanations for the observed associations between economic difficulties and health by analysing the contribution of health behaviours, living arrangements and work-family conflicts. The survey data were derived from the Finnish Helsinki Health Study baseline surveys in 2000-2002 among the City of Helsinki employees aged 40-60 years, and from the fifth phase of the London-based Whitehall II study (1997-9) which is a prospective study of civil servants aged 35-55 years at the time of recruitment. The data collection in the two countries was harmonised to safeguard maximal comparability. Physical functioning was measured with the Short Form (SF-36) physical component summary and common mental disorders with the General Health Questionnaire (GHQ-12). Socioeconomic circumstances were parental education, childhood economic difficulties, own education, occupational class, household income, housing tenure, and current economic difficulties. Further explanatory factors were health behaviours, living arrangements and work-family conflicts. The main statistical method used was logistic regression analysis. Analyses were conducted separately for the two sexes and two cohorts. Childhood and current economic difficulties were associated with poorer physical functioning and common mental disorders generally in both cohorts and sexes. Conventional dimensions of socioeconomic circumstances i.e. education, occupational class and income were associated with physical functioning and mediated each other’s effects, but in different ways in the two cohorts: education was more important in Helsinki and occupational class in London. The associations of economic difficulties with health were partly explained by work-family conflicts and other socioeconomic circumstances in both cohorts and sexes. In conclusion, this study on two country-specific cohorts confirms that different dimensions of socioeconomic circumstances are related but not interchangeable. They are also somewhat differently associated with physical and mental domains of health. In addition to conventionally measured dimensions of past and present socioeconomic circumstances, economic difficulties should be taken into account in studies and attempts to reduce health inequalities. Further explanatory factors, particularly conflicts between work and family, should also be considered when aiming to reduce inequalities and maintain the health of employees.

Community forestry and environmental literacy in northern Thailand : Towards collaborative natural resource management and conservation

Conservation and sustainable management of tropical forests needs a holistic approach: in addition to ecological concerns, socio-economic issues including cultural aspects must be taken into consideration. An ability to adapt practices is a key to successful collaborative natural resource management. Achieving this requires local participation and understanding of local conceptions of the environment. This study examined these issues in the context of northern Thailand. Northern uplands are the home of much of the remaining natural forest in Thailand and several ethnic minority groups commonly referred to as hill tribes. The overall purpose of this study was to grasp a regional view of an ethnically diverse forested area and to elicit prospects to develop community forestry for conservation purposes and for securing people s livelihood. Conservation was a central goal of management as the forests in the area were largely designated as protected. The aim was to study local perceptions, objectives, values and practices of forest management, under the umbrella of the concept environmental literacy, as well as the effects of forest policy on community management goals and activities. Environmental literacy refers to holistic understanding of the environment. It was used as a tool to examine people s views, interests, knowledge and motivation associated to forests. The material for this study was gathered in six villages in Chiang Mai Province. Three minority groups were included in the study, the Karen, Hmong and Lawa, and also the Thai. Household and focus group interviews were conducted in the villages. In addition, officials at district, regional and national levels, workers of non-governmental organisations, and academics were interviewed, and some data were gathered from the students of a local school. The results showed that motivation for protecting the forests existed among each ethnic group studied. This was a result of culture and traditions evolved in the forest environment but also of a need to adapt to a changed situation and environment and to outside pressures. The consequences of deforestation were widely agreed on in the villages, and the impact of socio-economic changes on the forests and livelihood was also recognised. The forest was regarded as a source of livelihood providing land, products and services essential to the people inhabiting rural uplands. Traditions, fire control, cooperation, reforestation, separation of protected and utilisable areas, and rules were viewed as central for conservation. For the villagers, however, conservation meant sustainable use, whereas the government has tended to prefer strict restrictions on forest resource use. Thus, conflicts had arisen. Between communities, cooperation was more dominant than conflict. The results indicated that the heterogeneity of forest dwellers, although it has to be recognised, should not be overemphasised: ethnic diversity can be considered as no major obstacle for successful community forestry. Collaborative management is particularly important in protected areas in order to meet the conservation goals while providing opportunities for livelihood. Forest management needs more positive incentives and increased dialogue.

Management of multi-scale forest resource data over time

During the last decades there has been a global shift in forest management from a focus solely on timber management to ecosystem management that endorses all aspects of forest functions: ecological, economic and social. This has resulted in a shift in paradigm from sustained yield to sustained diversity of values, goods and benefits obtained at the same time, introducing new temporal and spatial scales into forest resource management. The purpose of the present dissertation was to develop methods that would enable spatial and temporal scales to be introduced into the storage, processing, access and utilization of forest resource data. The methods developed are based on a conceptual view of a forest as a hierarchically nested collection of objects that can have a dynamically changing set of attributes. The temporal aspect of the methods consists of lifetime management for the objects and their attributes and of a temporal succession linking the objects together. Development of the forest resource data processing method concentrated on the extensibility and configurability of the data content and model calculations, allowing for a diverse set of processing operations to be executed using the same framework. The contribution of this dissertation to the utilisation of multi-scale forest resource data lies in the development of a reference data generation method to support forest inventory methods in approaching single-tree resolution.

Is prosopis a curse or a blessing? : An ecological economic analysis of an invasive alien tree species in Sudan.

The issue of the usefulness of different prosopis species versus their status as weeds is a matter of hot debate around the world. The tree Prosopis juliflora had until 2000 been proclaimed weedy in its native range in South America and elsewhere in the dry tropics. P. juliflora or mesquite has a 90-year history in Sudan. During the early 1990s a popular opinion in central Sudan and the Sudanese Government had begun to consider prosopis a noxious weed and a problematic tree species due to its aggressive ability to invade farmlands and pastures, especially in and around irrigated agricultural lands. As a consequence prosopis was officially declared an invasive alien species also in Sudan, and in 1995 a presidential decree for its eradication was issued. Using a total economic valuation (TEV) approach, this study analysed the impacts of prosopis on the local livelihoods in two contrasting irrigated agricultural schemes. Primarily a problem-based approach was used in which the derivation of non-market values was captured using ecological economic tools. In the New Halfa Irrigation Scheme in Kassala State, four separate household surveys were conducted due to diversity between the respective population groups. The main aim was here to study the magnitude of environmental economic benefits and costs derived from the invasion of prosopis in a large agricultural irrigation scheme on clay soil. Another study site, the Gandato Irrigation Scheme in River Nile State represented impacts from prosopis that an irrigation scheme was confronted with on sandy soil in the arid and semi-arid ecozones along the main River Nile. The two cases showed distinctly different effects of prosopis but both indicated the benefits to exceed the costs. The valuation on clay soil in New Halfa identified a benefit/cost ratio of 2.1, while this indicator equalled 46 on the sandy soils of Gandato. The valuation results were site-specific and based on local market prices. The most important beneficial impacts of prosopis on local livelihoods were derived from free-grazing forage for livestock, environmental conservation of the native vegetation, wood and non-wood forest products, as well as shelterbelt effects. The main social costs from prosopis were derived from weeding and clearing it from farm lands and from canalsides, from thorn injuries to humans and livestock, as well as from repair expenses vehicle tyre punctures. Of the population groups, the tenants faced most of the detrimental impacts, while the landless population groups (originating from western and eastern Sudan) as well as the nomads were highly dependent on this tree resource. For the Gandato site the monetized benefit-cost ratio of 46 still excluded several additional beneficial impacts of prosopis in the area that were difficult to quantify and monetize credibly. In River Nile State the beneficial impact could thus be seen as completely outweighing the costs of prosopis. The results can contributed to the formulation of national and local forest and agricultural policies related to prosopis in Sudan and also be used in other countries faced with similar impacts caused by this tree.

From bark bread to pizza - Food and exceptional circumstances: reactions of Finnish society to crises of food supply This study on the food supply under exceptional circumstances lies within the nutritional, historical and social sciences. The perspective and questions come under nutrition science, but are part of social decision-making. The study focuses on the first and second world wars as well as on contemporary society at the beginning of the 21st century. The main purpose of this study is to explore how Finnish society has responded to crises and what measures it has taken to sustain institutional food services and the food supply of households. The particular study interests include the school catering and food services in hospitals during the world wars. The situation in households is reflected in the counseling work carried out by state-run or civic organisations. Interest also focuses on the action of the scientific community. The decisions made in Finland are projected onto the solutions developed in some other European countries. The study is based primarily on the archive documents and annual reports prepared by food and health care authorities. Major source materials include scientific and professional publications. The evaluation of the situation in contemporary Finnish society is based on corresponding emergency plans and guidelines. The written material is supplemented by discussions with experts. Food rationing during the WWI and WWII differed in extent, details and unity. The food intake of some population groups was occasionally inadequate both in quantity, quality and safety. The counseling of the public focused on promoting self-sufficiency, improving cooking skills and widening food habits. One of the most vulnerable groups in regard to nutrition was long-term patients in institutions. As for future development, the world wars were never-theless important periods for public food services and counseling practices. WWII was also an important period for product development in the food industry. Significant work on food substitutes was carried out by Professor Carl Tigerstedt during WWI. The research of Professors A. I. Virtanen and Paavo Simola during WWII focused on vitamins. Crises threatening societies now differ from those faced a hundred years ago. Finland is bet-ter prepared, but in many ways more vulnerable to and dependent on other actors. Food rationing is a severe means of handling the scarcity of food, which is why contemporary society relies primarily on preparedness planning. Civic organisations played a key role during the world wars, and establishing an emergency food supply remains on their agenda. Although the objective of protecting the population remains the same for nutrition, food production, and food consumption, threat scenarios and the knowledge and skill levels of citizens are constantly changing. Continuous monitoring and evaluation is therefore needed.

Determinants of farmer retirement and farm succession in Finland

In the past decade, the Finnish agricultural sector has undergone rapid structural changes. The number of farms has decreased and the average farm size has increased when the number of farms transferred to new entrants has decreased. Part of the structural change in agriculture is manifested in early retirement programmes. In studying farmers exit behaviour in different countries, institutional differences, incentive programmes and constraints are found to matter. In Finland, farmers early retirement programmes were first introduced in 1974 and, during the last ten years, they have been carried out within the European Union framework for these programmes. The early retirement benefits are farmer specific and de-pend on the level of pension insurance the farmer has paid over his active farming years. In order to predict the future development of the agricultural sector, farmers have been frequently asked about their future plans and their plans for succession. However, the plans the farmers made for succession have been found to be time inconsistent. This study estimates the value of farmers stated succession plans in predicting revealed succession decisions. A stated succession plan exists when a farmer answers in a survey questionnaire that the farm is going to be transferred to a new entrant within a five-year period. The succession is revealed when the farm is transferred to a suc-cessor. Stated and revealed behaviour was estimated as a recursive Binomial Probit Model, which accounts for the censoring of the decision variables and controls for a potential correlation between the two equations. The results suggest that the succession plans, as stated by elderly farmers in the questionnaires, do not provide information that is significant and valuable in predicting true, com-pleted successions. Therefore, farmer exit should be analysed based on observed behaviour rather than on stated plans and intentions. As farm retirement plays a crucial role in determining the characteristics of structural change in agriculture, it is important to establish the factors which determine an exit from farming among eld-erly farmers and how off-farm income and income losses affect their exit choices. In this study, the observed choice of pension scheme by elderly farmers was analysed by a bivariate probit model. Despite some variations in significance and the effects of each factor, the ages of the farmer and spouse, the age and number of potential successors, farm size, income loss when retiring and the location of the farm together with the production line were found to be the most important determi-nants of early retirement and the transfer or closure of farms. Recently, the labour status of the spouse has been found to contribute significantly to individual retirement decisions. In this study, the effect of spousal retirement and economic incentives related to the timing of a farming couple s early retirement decision were analysed with a duration model. The results suggest that an expected pension in particular advances farm transfers. It was found that on farms operated by a couple, both early retirement and farm succession took place more often than on farms operated by a single person. However, the existence of a spouse delayed the timing of early retirement. Farming couples were found to co-ordinate their early retirement decisions when they both exit through agricultural retirement programmes, but such a co-ordination did not exist when one of the spouses retired under other pension schemes. Besides changes in the agricultural structure, the share and amount of off-farm income of a farm family s total income has also increased. In the study, the effect of off-farm income on farmers retirement decisions, in addition to other financial factors, was analysed. The unknown parameters were first estimated by a switching-type multivariate probit model and then by the simulated maxi-mum likelihood (SML) method, controlling for farmer specific fixed effects and serial correlation of the errors. The results suggest that elderly farmers off-farm income is a significant determinant in a farmer s choice to exit and close down the farm. However, off-farm income only has a short term effect on structural changes in agriculture since it does not significantly contribute to the timing of farm successions.

Lake sediment research as a part of lake management - case studies and implications from southern Finland

In Finland one of the most important current issues in the environmental management is the quality of surface waters. The increasing social importance of lakes and water systems has generated wide-ranging interest in lake restoration and management, concerning especially lakes suffering from eutrophication, but also from other environmental impacts. Most of the factors deteriorating the water quality in Finnish lakes are connected to human activities. Especially since the 1940's, the intensified farming practices and conduction of sewage waters from scattered settlements, cottages and industry have affected the lakes, which simultaneously have developed in to recreational areas for a growing number of people. Therefore, this study was focused on small lakes, which are human impacted, located close to settlement areas and have a significant value for local population. The aim of this thesis was to obtain information from lake sediment records for on-going lake restoration activities and to prove that a well planned, properly focused lake sediment study is an essential part of the work related to evaluation, target consideration and restoration of Finnish lakes. Altogether 11 lakes were studied. The study of Lake Kaljasjärvi was related to the gradual eutrophication of the lake. In lakes Ormajärvi, Suolijärvi, Lehee, Pyhäjärvi and Iso-Roine the main focus was on sediment mapping, as well as on the long term changes of the sedimentation, which were compared to Lake Pääjärvi. In Lake Hormajärvi the role of different kind of sedimentation environments in the eutrophication development of the lake's two basins were compared. Lake Orijärvi has not been eutrophied, but the ore exploitation and related acid main drainage from the catchment area have influenced the lake drastically and the changes caused by metal load were investigated. The twin lakes Etujärvi and Takajärvi are slightly eutrophied, but also suffer problems associated with the erosion of the substantial peat accumulations covering the fringe areas of the lakes. These peat accumulations are related to Holocene water level changes, which were investigated. The methods used were chosen case-specifically for each lake. In general, acoustic soundings of the lakes, detailed description of the nature of the sediment and determinations of the physical properties of the sediment, such as water content, loss on ignition and magnetic susceptibility were used, as was grain size analysis. A wide set of chemical analyses was also used. Diatom and chrysophycean cyst analyses were applied, and the diatom inferred total phosphorus content was reconstructed. The results of these studies prove, that the ideal lake sediment study, as a part of a lake management project, should be two-phased. In the first phase, thoroughgoing mapping of sedimentation patterns should be carried out by soundings and adequate corings. The actual sampling, based on the preliminary results, must include at least one long core from the main sedimentation basin for the determining the natural background state of the lake. The recent, artificially impacted development of the lake can then be determined by short-core and surface sediment studies. The sampling must be focused on the basis of the sediment mapping again, and it should represent all different sedimentation environments and bottom dynamic zones, considering the inlets and outlets, as well as the effects of possible point loaders of the lake. In practice, the budget of the lake management projects of is usually limited and only the most essential work and analyses can be carried out. The set of chemical and biological analyses and dating methods must therefore been thoroughly considered and adapted to the specific management problem. The results show also, that information obtained from a properly performed sediment study enhances the planning of the restoration, makes possible to define the target of the remediation activities and improves the cost-efficiency of the project.

Optimal Punishment of Economic Crime: A Study on Bankruptcy Crime This thesis researches whether the punishment practise of bankruptcy crimes is optimal in light of Gary S. Becker’s theory of optimal punishment. According to Becker, a punishment is optimal if it eliminates the expected utility of the crime for the offender and - on the other hand - minimizes the cost of the crime to society. The decision process of the offender is observed through their expected utility of the crime. The expected utility is calculated based on the offender's probability of getting caught, the cost of getting caught and the profit from the crime. All objects including the punishment are measured in cash. The cost of crimes to the society is observed defining the disutility caused by the crime to the society. The disutility is calculated based on the cost of crime prevention, crime damages, punishment execution and the probability of getting caught. If the goal is to minimize the crime profits, the punishments of bankruptcy crimes are not optimal. If the debtors would decide whether or not to commit the crime solely based on economical consideration, the crime rate would be multiple times higher than the current rate is. The prospective offender relies heavily on non-economic aspects in their decision. Most probably social pressure and personal commitment to oblige the laws are major factors in the prospective criminal’s decision-making. The function developed by Becker measuring the cost to society was not useful in the measurement of the optimality of a punishment. The premise of the function that the costs of the society correlate to the costs for the offender from the punishment proves to be unrealistic in observation of the bankruptcy crimes. However, it was observed that majority of the cost of crime for the society are caused by the crime damages. This finding supports the preventive criminal politics.
