Essays on socially optimal phosphorus policies in crop production

Phosphorus is a nutrient needed in crop production. While boosting crop yields it may also accelerate eutrophication in the surface waters receiving the phosphorus runoff. The privately optimal level of phosphorus use is determined by the input and output prices, and the crop response to phosphorus. Socially optimal use also takes into account the impact of phosphorus runoff on water quality. Increased eutrophication decreases the economic value of surface waters by Deteriorating fish stocks, curtailing the potential for recreational activities and by increasing the probabilities of mass algae blooms. In this dissertation, the optimal use of phosphorus is modelled as a dynamic optimization problem. The potentially plant available phosphorus accumulated in soil is treated as a dynamic state variable, the control variable being the annual phosphorus fertilization. For crop response to phosphorus, the state variable is more important than the annual fertilization. The level of this state variable is also a key determinant of the runoff of dissolved, reactive phosphorus. Also the loss of particulate phosphorus due to erosion is considered in the thesis, as well as its mitigation by constructing vegetative buffers. The dynamic model is applied for crop production on clay soils. At the steady state, the analysis focuses on the effects of prices, damage parameterization, discount rate and soil phosphorus carryover capacity on optimal steady state phosphorus use. The economic instruments needed to sustain the social optimum are also analyzed. According to the results the economic incentives should be conditioned on soil phosphorus values directly, rather than on annual phosphorus applications. The results also emphasize the substantial effects the differences in varying discount rates of the farmer and the social planner have on optimal instruments. The thesis analyzes the optimal soil phosphorus paths from its alternative initial levels. It also examines how erosion susceptibility of a parcel affects these optimal paths. The results underline the significance of the prevailing soil phosphorus status on optimal fertilization levels. With very high initial soil phosphorus levels, both the privately and socially optimal phosphorus application levels are close to zero as the state variable is driven towards its steady state. The soil phosphorus processes are slow. Therefore, depleting high phosphorus soils may take decades. The thesis also presents a methodologically interesting phenomenon in problems of maximizing the flow of discounted payoffs. When both the benefits and damages are related to the same state variable, the steady state solution may have an interesting property, under very general conditions: The tail of the payoffs of the privately optimal path as well as the steady state may provide a higher social welfare than the respective tail of the socially optimal path. The result is formalized and an applied to the created framework of optimal phosphorus use.

Onko varhaisen tuen päiväkoti mahdollinen? : Tutkimus varhaiskasvatuksen yhteisöllisestä kehittämisestä

Is the early childhood day care facility possible? The research considering communal development of the early education. In Finland mothers and fathers look after 400 000 pre-school children. Half of these attend day care facilities, in which 50 000 staff are employed. The aim of this research is to develop co-operation practices within the day care centre. This research refines and expands my own interest in and knowledge of day care management and content development. The basis of the research draws upon ethnographic material covering the period 1999–2005. The day care centre chosen as a central informant was the first suburban centre founded in 1963, and it provided a rich local and welfare state research perspective. It became clear that the day care facility’s co-operation practices formed the basis of bringing up children and at the same time produced a new multi-operational and multi-layered community for child participation. Adult day care centre workers bringing up the children as a professional work and solutions defining the conditions for the work are expressed in a child’s upbringing. This obviously has an impact in where as the development of communities. From the human and community scientific point of view, the group of youngest children will take up a future position as key players in communities as essential actors and reformers. The research was carried out as multiphase and multiscientific practical research and iterative data formation. The results verified that the co-operation between parents and day care staff produces important benefits for all the stakeholders. However, the day care staff has difficulties in implementing the benefits. During the research process, it became clear that conceptually day care staff saw the practices as ”very important, but not easily realised in practice”. As a result this demanded further research to address this issue and to extend this to the carefacility’s co-operation practises and their communal and social conditions. The research looks at the carefacility’s co-operation with key stakeholders. At the same time it undertakes an analytical and historical examination of carefacilitys’s with an experimental focus as two day care centres chosen as experimental objects. The results of the research showed that the benefits gained by children were determined by the day care centre’s socio-political structure and the parent’s resources. The research framework categorised early childhood education as generational and gender based structures. As part of the research, the strains endemic to these formations have been examined. The system for bringing up children was created as part of a so called welfare state project by implemented by the Day Care Act in year 1973. The law secured the subjective right for every pre-school child to have access to day care facilities. The law also introduced a labour and sosiopolitical phase and the refinement of the day care facility’s education-care concept. The latest phase that started during the early 1990´s was called the market-based social services strategy. As a result of this phase, state support was limited and the screening function of the law was relaxed. This new strategy resulted in a divisive and bureaucratic social welfare system, that individualised and segregated children and their parents, leaving some families outside the communal and welfare state benefit net. The modern day care centre is a hybrid of different aims. Children spend longer and more irregular time in day care. The families are multicultural and that requires more training for the staff. The work in day care has been enhanced, for example he level of education for the staff has been lowered and productivity has been improved. However, administrative work and different kinds of support and net work functions together with the continuous change have taken over from the work done face to face with children. Staff experiences more pressure as the management and the work load has increased. Consequently the long-term planning and daily implementation of the nuclear task of the day care facility is difficult to control. This will have an effect on both motivation and manageability of the work. Overall quality of the early childhood upbringing has been weakened. The possibilities for the near future were tested in the two day care centres chosen as an experi-ment objects. The analysis of these experiments showed that generative interaction work will benefit everyone: children, parents and employees. The main results of the research are new concepts of an early support day care centre, which can be empirically and theoretically possi-ble for development the near future. Key words: Day care facility’s co-operation practises, early childhood education as generational structure, child’s multi-operational and multi-layered community, multi-subjective operator, generative interaction work, communal composition.

Ihanteena vapaaehtoisuus : Diakoniatyö Porvoon hiippakunnan seurakunnissa, erityisesti Iitin ja Tampereen rovastikunnissa vuosina 1897-1923

The Ideal of Volunteerism. An institutional approach to social welfare work in the parishes of the Diocese of Porvoo especially in the deaneries of Iitti and Tampere, Finland, in the years 1897-1923 Social welfare work (also known as diakonia) has achieved a high status in the Evangelical Lutheran Church of Finland. Since 1944, provisions of the Finnish Church Act have obliged each parish to employ at least one deacon or deaconess. This study sets out to examine the background and development of social welfare work in the Evangelical Lutheran Church of Finland from the 1890s to the 1920s, by which time social welfare work had become an established practice in the Church. The study investigates the development of social welfare work on the level of parishes. The main source material was collected from sixteen parishes in the Diocese of Porvoo especially in the deaneries of Iitti and Tampere. In the 1890s, two approaches were used in church social work in Finland. The dioceses of Kuopio, Savonlinna and Turku pursued a congregational approach to social work, while the Diocese of Porvoo employed an institutional approach, mainly because of the influence of Bishop Herman Råbergh. This study charts the formation of church social work in Finnish parishes, which took place during a period of tension between the two approaches. The institutional approach to church social work adopted by the Diocese of Porvoo was based on the German system of Asisters= houses@, in which deaconess institutes sent parish sisters to serve congregations. The parish or, in many cases, a separate association dedicated to church social work paid an annual fee to the deaconess institute, which took care of the parish sisters in old age. In the institutional approach, volunteers were recruited to carry out church social work. It was considered as inappropriate to use tax revenue or other public funding for church social work, which was supposed to be based on Christian love for one=s fellow humans and the needy, and for which only voluntary financial contributions were supposed to be used. In the congregational approach, church social work was directly based on the efforts of the parish. The approach relied on the administrative bodies of parishes and the Church, and tax revenue collected by the parishes, as well as other forms of public funding, could be used to carry out the social welfare work. The parishes employed deacons and deaconesses and paid their salaries. The approaches described above were not pursued in their ideal forms; instead, many variations existed. However, in principle, the social welfare work undertaken by the parishes of the Diocese of Porvoo was based on the institutional approach, while the congregational approach was largely employed elsewhere in Finland. Both of the approaches were viable. Parishes began to employ deacons and deaconesses as of the 1890s. The number of parishes which had hired a deacon or deaconess increased particularly in the 1910s, by which time 60% of parishes had employed one. This level was maintained until 1944 when each parish in the Evangelical Lutheran Church of Finland was obliged to employ a deacon or deaconess. Deaconesses usually worked as travelling nurses. The autonomous status of Finland as part of the Russian Empire did not give Finns the right to develop legislation on social affairs and health care. Consequently, the legislation process did not begin until Finland gained its independence in 1917. The social welfare work carried out by parishes and a number of voluntary organisations satisfied the emerging need for medical treatment in Finnish society. Neither the government nor the municipalities had sufficient resources to provide this treatment. Based on the ideal of volunteerism, the institutional social work practiced in the Diocese of Porvoo ran into serious difficulties at the end of the First World War. Because of severe inflation, prices began to rise as of 1915 and tripled in 1917-1918. During the same period, Finnish society went through a deep crisis which escalated into Civil War in spring 1918. This period of economic and social turmoil marked a turning-point which led to a weakening of the status of institutional social work in parishes. Voluntary efforts were no longer sufficient to maintain the practice. In contrast, congregational social work, which was based on public funding, was able to cope with the changes and survived the crisis. The approach to social work adopted by the Diocese of Porvoo turned out to be no more than a brief detour in the history of social work in the Evangelical Lutheran Church of Finland. At the start of the 1920s, the two approaches were integrated into a common vision for establishing church social work as a statutory practice in parishes.

NORDEK : A Plan for Increased Nordic Economic Co-operation and Integration 1968-1970

For the first time the attempt of Denmark, Finland, Norway and Sweden to increase Nordic economic co-operation and integration (NORDEK 1968-1970) is analysed by using records from the four governments archives and interviews with central actors participating. A dominating argument has until now been that dynamics in Nordic economic integration is different from dynamics in European integration. This archive based study disproves the myth however of ideological Nordism and of short term political developments outside Norden as most important for the NORDEK initiative. The NORDEK initiative was actually more a consequence of a long term socioeconomic and socio-political path dependant process. The study also disproves the myth that the NORDEK plan was a political and ideological symbol without socioeconomic substance. The purpose with NORDEK was to create a better basis for generating economic growth and social welfare. The proposed NORDEK institutions were therefore developed to promote economic progress. The study finally shows that the NORDEK failure in 1970 was not a result of lacking economic rationale or incompatible economic interests. The failure was a result of a power struggle in Finnish domestic policy and lacking political will in the other Nordic countries to continue without Finland.

Sikiöaikana päihteille altistuneiden lasten kasvuympäristö ja kehitys

Life of children exposed to alcohol or drugs in utero This study focused on the growth environment, physical development and socio-emotional development of children, aged 16 and under, who had been exposed to alcohol (n=78) or drugs (n=15) in utero. The aim of the study was to obtain a comprehensive picture of the living conditions of these children and to examine the role of the growth environment in their development. The study was carried out using questionnaires, written life stories and interviews. Attachment theory was used as a background theory in the study. Over half of the children exposed to alcohol were diagnosed with foetal alcohol syndrome (FAS), one quarter was diagnosed with foetal alcohol effects (FAE), and one fifth had no diagnosis. Most of the children exposed to drugs had been exposed to either amphetamines or cannabis, and a smaller number to heroin. Some of the children exposed to alcohol were mentally handicapped or intellectually impaired. The children exposed to drugs did not exhibit any serious learning difficulties but a considerable number of them had socio-emotional development problems. Language and speech problems and attention, concentration and social interaction problems were typical among both the children exposed to alcohol and those exposed to drugs. Only one child had been placed into long-term foster care in a family immediately after leaving the maternity hospital. In biological families there had been neglect, violence, mental health problems, crime and unemployment, and many parents were already dead. Two of the children had been sexually abused and four were suspected of having been abused. From the point of view of the children's development, the three most critical issues were 1) the range of illnesses and handicaps that had impaired their functional capacity as a result of their prenatal exposure to alcohol, 2) child's age at the time of placement on a long-term basis, and 3) the number of their traumatic experiences. The relationship with their biological parents after placement also played a role. Children with symptoms were found in all diagnosis categories and types of exposure. Children with the smallest number of symptoms were found among those who had never lived with their biological parents. Almost all children were exhibiting strong symptoms at the time of placement in foster care. In most cases, they were behaving in a disorderly manner towards others, but some children were withdrawn. The most conspicuous feature among those with the most severe symptoms was their disorganized behaviour. Placement in a foster family enhanced the children's development, but did not solve the problems. The foster parents who brought these children up did not receive as much therapy for the children and support for the upbringing as they appear to have needed. In Finland, transfer to long-term custody is based on strict criteria. The rights of children prescribed in the child protection law are not fulfilled in practice. Key words: FASD, FAS, FAE, alcohol exposure, drugs exposure, illegal drugs, early interaction, child development, attachment

Sosiaalipalveluja kaikille ja kaiken ikää? : Tutkimus suomalaisten mielipiteistä ja kokemuksista sosiaalipalveluista sekä niiden suhteesta legitimiteettiin

This research analyses opinions on the system of social welfare services from the point of view of clients and the public in general in Finland. The approach is quantitative, drawing on theories of the welfare-state tradition. The data used comes from the comprehensive Welfare and Services in Finland survey compiled by STAKES. While previous research on the welfare state has predominantly focused on surveying public opinion on social protection, this research focuses on social welfare services. The main focus of this research is on publicly funded care provided by municipal social welfare services. In this research, social welfare services include child day care, services for people with disabilities, home-help services, counselling by social workers and social assistance. The research considered in particular whether the clients or the population has different opinions towards social welfare services or social benefits. In addition, the research partly covers areas of informal care provided by family and friends. The research material consisted of the STAKES Welfare and Services in Finland survey. The data was compiled in 2004 and 2006 by Statistics Finland. The research comprises five articles. Additional data have been extracted from social welfare statistics and registers. Multiple approaches were applied in the survey on welfare and services the methods in this research included interviews by phone and mail, and register data. The sample size was 5 810 people in 2004 and 5 798 in 2006. The response rates were 82.7% and 83.7%, respectively. The results indicate that a large majority (90%) of the Finnish population is of the opinion that the public sector should bear the main responsibility for organising social and health services. The system of social welfare services and its personnel have strong public support 73% and 80% respectively. However, new and even negative tones have emerged in the Finnish debate on social welfare services. Women are increasingly critical of the performance of social welfare services and the level of social protection. Furthermore, this study shows that women more often than men wish to see an increase in the amount of privately organised social welfare services. Another group critical of the performance of social welfare services are pensioners. People who had used social welfare services were more critical than those who had not used them. Thus, the severest criticism was received from the groups who use and gain most from public services and benefits. However, the education and income variables identified in earlier studies no longer formed a significant dividing line, although people with higher education tend to foster a more positive view of the performance of social welfare services as well as the level of social protection. Income differences did not bear any significance, that is, belonging to a high or low income group was not a determining factor in the attitude towards social welfare services or social benefits. According to the research, family and friends still form an informal yet significant support network in people's everyday lives, and its importance has not been diminished by services provided by the welfare state. The Finnish public considers child day care the most reliable form of social welfare services. Indeed, child day care has become the most universal sector of our system of social welfare services. Other services that instil confidence included counselling by social workers and services for people with disabilities. On the other hand, social assistance and home-help services received negative feedback. The negative views were based on a number of arguments. One argument contends that the home-help service system, which was originally intended for universal use, is crumbling. The preventive role of home-help services has been reduced. These results mirror the increasingly popular opinion that social welfare services are not produced for all those who need them, but to an increasing extent for a select few of them. Municipalities are struggling with their finances and this, combined with negative publicity, has damaged the public's trust in some municipal social welfare services. A welfare state never achieves a stable condition, but must develop over time, as the world around it changes. Following the 1990's recession, we are now in a position where we can start to develop a system that responds to the needs of the next generation. Study results indicating new areas of dissatisfaction reflect the need to develop and improve the services provided. It is also increasingly essential that social welfare services pay attention to the opinions of clients and the public. Should the gap between opinions and actual activities increase, the legitimacy of the whole system would be questioned. Currently, the vast majority of Finns consider the system of social welfare services adequate, which provides us with the continuity required to maintain and improve client-oriented and reasonably priced social welfare services. Paying attention to the signals given by clients and the general public, and reacting to them accordingly, will also secure the development and legitimacy of the system in the future.

Climate change and agriculture: theory and application of mitigation policies

Agriculture’s contribution to climate change is controversial as it is a significant source of greenhouse gases but also a sink of carbon. Hence its economic and technological potential to mitigate climate change have been argued to be noteworthy. However, social profitability of emission mitigation is a result from factors among emission reductions such as surface water quality impact or profit from production. Consequently, to value comprehensive results of agricultural climate emission mitigation practices, these co-effects to environment and economics should be taken into account. The objective of this thesis was to develop an integrated economic and ecological model to analyse the social welfare of crop cultivation in Finland on distinctive cultivation technologies, conventional tillage and conservation tillage (no-till). Further, we ask whether it would be privately or socially profitable to allocate some of barley cultivation for alternative land use, such as green set-aside or afforestation, when production costs, GHG’s and water quality impacts are taken into account. In the theoretical framework we depict the optimal input use and land allocation choices in terms of environmental impacts and profit from production and derive the optimal tax and payment policies for climate and water quality friendly land allocation. The empirical application of the model uses Finnish data about production cost and profit structure and environmental impacts. According to our results, given emission mitigation practices are not self-evidently beneficial for farmers or society. On the contrary, in some cases alternative land allocation could even reduce social welfare, profiting conventional crop cultivation. This is the case regarding mineral soils such as clay and silt soils. On organic agricultural soils, climate mitigation practices, in this case afforestation and green fallow give more promising results, decreasing climate emissions and nutrient runoff to water systems. No-till technology does not seem to profit climate mitigation although it does decrease other environmental impacts. Nevertheless, the data behind climate emission mitigation practices impact to production and climate is limited and partly contradictory. More specific experiment studies on interaction of emission mitigation practices and environment would be needed. Further study would be important. Particularly area specific production and environmental factors and also food security and safety and socio-economic impacts should be taken into account.

Vain hätapua? : Taloudellinen avustaminen diakoniatyön professionaalisen itseymmärryksen ilmentäjänä

Financial Help Alone? Financial help as an exponent of professional diaconal work One essential form of helping people in the Evangelical Lutheran Church s diaconal work is providing economic aid. It can be seen as work which is in accordance with the spirit of the Church Order (4:3). One of the tasks of diaconal work, determined by the Church Order, is to help those whose distress is the greatest and who have no other source of help. This financial support has become a permanent and essential working method, which has also created tension of various kinds. Financial support has been criticized, especially when the support has been used to fill a gap in the social services provided by the government. It has been argued that diaconal work has been forced to take on responsibility for tasks that belong to the welfare state. The tensions involved in the financial support of diaconal work do not only concern the patching up and supplementing of the deficiencies in the welfare state s services but also the question of diaconal workers self-understanding of financial support and how it relates to their professionalism. In this thesis, I examine the experiences and visions diaconal workers have concerning financial support in their work with clients. The viewpoint of my work is the diaconal workers own experiences and interpretations of the meaning of financial support in customer service. In the articles of my thesis, I examined the meanings that diaconal workers gave to financial support in the aspects of work motivation, empowerment, expertise and tensions. The research material of my articles consists of three different data, which are theme interviews from diaconal workers, a survey from diaconal workers of Espoo and a diaconal barometer of 2009. I have analysed the theme interviews and the survey using qualitative content analysis. The results of my articles showed that diaconal workers motivation in tasks concerning economic aid was sustained by the nature and spiritual aspects of support activities. Work that supported empowerment through financial assistance meant influencing the client s personal life, community and local ties and structural circumstances of the surrounding society. Diaconal workers expertise in financial support work can be characterised as horizontal, which means that the expertise was built on acknowledging the client s dignity, the uniqueness of the client s life situation and listening to the client s own voice. Diaconal workers were also experts in community and area-based work. The tensions in financial support work are linked to its unofficial and undefined role in the field of social welfare and the inability of other aiding parties to respond to their duties. The results of my thesis on the experiences and visions of financial support reveal that it is multilateral and multidimensional. Diaconal workers used financial support to help the clients, taking into account their individual, communal, social and spiritual context. The professionalism of this financial support is reflectively related to the client s need of help and the spontaneity and unexpectedness of the situation. Support work was deeply bound to diaconal workers experiences of spirituality as the basic value in their work, the foundation of their idea of humanity and their method of helping others. In different tasks of financial support diaconal workers balanced between traditional, individual client work based on caritas and working methods which are based on supporting the individual s empowerment and active citizenship, as in postmodern social work. Diaconal workers experiences of financial support illustrated the transition or turning point in the professionalism of diaconal work, which involves finding one s own, stronger and clearer professional identity than earlier with respect to other helpers in society. Creating a unique identity is part of the empowerment process of diaconal work, in which it must define its professional role by itself. In postmodern pluralism and the fragmented context of diaconal activities, the question arose as to whether the spiritual traditions and traditional values of diaconal work support the modifications and adaptations needed in new, unpredictable situations. Diaconal work is said to be fast to react, able to predict changes and adapt to those changes. To preserve its sensitive reactive ability, also in the complex postmodern world, it must retain its own views and orientations. Otherwise, the distinctive values and traditions of diaconal work might sustain static diaconal work, employee-centeredness and a smug attitude when defining beneficiaries and needs, which highlights the paternalism of diaconal work. Such paternalism may complicate the progress of working methods which are based on empowerment and citizenship.

Chinese immigrants to Finland: A qualitative study of housing, employment, access to health care and child care as sociological dimensions in their settlement process

The Master’s thesis is qualitative research based on interviews of 15 Chinese immigrants to Finland in order to provide a sociological perspective of the migration experience through the eyes of Chinese immigrants in the Finnish social welfare context. This research is mainly focused upon four crucial aspects of life in the settlement process: housing, employment, access to health care and child care. Inspired by Allardt’s theoretical framework ‘Having, Loving and Being’, social relationships and individual satisfaction are examined in the case of Chinese interviewees dealing with the four life aspects. Finland was not perceived as an attractive migration destination for most Chinese interviewees in the beginning. However, with longer residence in Finland, the Finnish social welfare system gradually became a crucial appealing factor in their permanent settlement in Finland. And meanwhile, social responsibility of attending their old parents in China, strong feelings of being isolated in Finland, and insufficient integration into the Finnish society were influential factors for their decision of returning to China. Social relationships with personal friends, migration brokers, schools, employers and family relatives had great influences in the four life aspects of Chinese immigrants in Finland. The social relationship with the Finnish social welfare sector is supportive to Chinese immigrants, but Chinese immigrants do not heavily rely on Finnish social protection. The housing conditions were greatly improved over time while the upward mobility in the Finnish labour market was not significant among Chinese immigrants. All Chinese immigrants were satisfied with their current housing by the time I interviewed them while most of them had subjective feelings of being alienated in the Finnish labour market, which seriously prevented them from integrating into the Finnish society. In general, Chinese immigrants were satisfied with the low cost of accessing the Finnish public health care services and affordable Finnish child day care services and financial subsidies for children from the Finnish social welfare sector. This research also suggests that employment is the central basis in well-being. Support from the Finnish social welfare sector can improve the satisfaction levels among immigrants, especially when it mitigates the effects of low-paid employment. As well, my empirical study of Chinese immigrants in Finland shows that Having (needs for materials), Loving (needs for social relations) and Being (needs for social integration) are all involved in the four concrete aspects (housing, employment, access to health care and child care).

Maidontuottajatila ja ravinnepolitiikka: Tilan toimintamekanismit, politiikan tarve ja ohjauskeinojen vaikuttavuus

Tutkielman tarkoituksena on rakentaa malli, jolla voidaan arvioida maitotilan toimintaa monipuolisesti ravinnehuuhtouman kannalta. Tavoitteena on ennen muuta analyyttinen tarkastelu siten, että kuitenkin huomioiden maidontuotannon ominaispiirteet, keskeisinä esimerkkeinä ravinnon, maidontuotannon ja lannan ominaisuuksien väliset riippuvuudet. Analyysissa tarkastellaan tilanomistajan yksityisen hyödynmaksimoinnin ja yhteiskunnan tavoitteiden eroavaisuutta. Lisäksi johdetaan optimaaliset ohjauskeinot ja arvioidaan eräiden yksinkertaisten ohjauskeinojen vaikuttavuutta. Mallin analysoinnin perusteella yksityinen ja yhteiskunnallinen optimiratkaisu eroavat toisistaan kaikkien päätösmuuttujien osalta. Ei voida kuitenkaan yleispätevästi sanoa muutosten merkittävyyttä tai suuntaa ottamatta kantaa mallin funktiomuotoihin ja parametriarvoihin. Optimaaliset ohjauskeinot tulisi asettaa keinolannoitteen ja lannan levitykselle, väkirehuruokinnalle ja säilörehun viljelylle, mutta ei eläinten määrälle. Toisaalta optimaaliset ohjauskeinot ovat hyvin monimutkaisia. Tarkasteltujen yksinkertaisempien ohjauskeinojen vaikuttavuutta ei voida tarkasti arvioida analyyttisella tasolla. Numeeristen tulosten perusteella yhteiskunnallisessa optimissa eläinmäärä olisi hieman yksityistä optimia pienempi, väkirehun käyttö vähäisempää, enemmän peltoa allokoitaisiin säilörehun viljelyyn ja lannoitustasot olisivat kautta linjan hieman pienemmät. Lannanlevitykset eroavat etäisyyden suhteen: molemmissa tapauksissa lannanlevityksen intensiteetti kasvaa kohti tilan keskusta kuljettaessa, mutta yksityisessä optimissa lähimmälle pellolle dumpataan kaikki ylimääräinen lanta, kun taas yhteiskunnallisessa optimissa lanta levitetään tasaisemmin eri pelloille. Ero kokonaishyvinvoinnissa jää pieneksi, mutta eläinmäärän kasvu kärjistäisi lannan dumppauksen aiheuttamia huuhtoumahaittoja. Yksinkertaisista ohjauskeinoista lannoitusrajoitus sekä ravinne- ja keinolannoitevero osoittautuivat kohtalaisen käyttökelpoisiksi numeeristen tulosten perusteella. Sen sijaan eläinmäärän rajoittaminen ja lannan kuljetuskustannuksia kompensoivat tuet vaikuttavat tulosten perusteella huonoilta ratkaisuilta.

Uutta, vanhaa ja lainattua : Tampereen Kaupunkilähetyksen kristillissosiaalisen työn asemoituminen hyvinvointivaltion rakentumisessa vuosina 1939−1973

The main purpose of this study was to provide a full account of the Christian social work carried out at the Tampere City Mission (TCM) as well as the Missions sphere of operations from the Second World War to the early 1970s, comprising a period of significant change. The study consists of charting the processes of change and connections within the activities of the TCM and how examining these were linked to the general tendencies of the period, in lay work, social work, professionalization and the representation of gender. The positioning of the activities is described on the basis of these tendencies. The main sources for the study were the archives of the Mission, for example the minutes of meetings, correspondences as well as annual reports, and the archives of its partners, such as the City of Tampere, the Evangelical Lutheran parishes of Tampere and the State Welfare Administration. The archives of the Helsinki, Turku and Stockholm Missions supplied comparison reference and other material. In particular, social welfare and Christian social work technical journals of were used as printed sources. The principal method used was the genetic method of historiology. The research subject was also evaluated from the point of view of third sector research in addition to that of professionalization studies and gender studies. By the beginning of the research period, the TCM had turned more and more dedicatedly into a multipurpose social service organization maintaining social services such as old people s homes and children´s homes. This development continued, even though new areas of activity emerged and older ones fell into disuse. Social innovations sprang up, marriage counseling being one of them. On the national level, the TCM pioneered the provision of sheltered industrial work for intellectually disabled persons as well as housing services for them. As new activities were initiated, they overlapped with the established ones, and the TCM handed some of its child protection functions over to the municipality, in accordance with the current adaptation theory. The use of its own property to produce ever-changing social services may be the reason why the association s work continued on with vitality. Functional networks and political aid in the field of social services also bolstered the association. As in other Nordic countries, nonprofit organizations served as partners rather than competitors, with the State establishing institutional welfare arrangements. In the 1960s the municipal takeover of social services impacted the TCM activities. Rules for government subsidies and municipal allowances were not well established; hence these funds were not easily available, making improvements difficult. The TCM was a community in which women had a relatively strong position and an opportunity to make a difference. Female staff were reasonably equal to men, and women worked as heads of a several institutions. Care work employed a number of men, which went against the traditional segregation of labour between the sexes. The TCM s operations were from early on very professionalized, and were developed with particular care. Keywords: Christian social work, third sector, professionalization, gender

Cancer survivors at work : Work-related problems and factors associated with their employment, work ability and social support from the work community

Due to the improved prognosis of many forms of cancer, an increasing number of cancer survivors are willing to return to work after their treatment. It is generally believed, however, that people with cancer are either unemployed, stay at home, or retire more often than people without cancer. This study investigated the problems that cancer survivors experience on the labour market, as well as the disease-related, sociodemographic and psychosocial factors at work that are associated with the employment and work ability of cancer survivors. The impact of cancer on employment was studied combining the data of Finnish Cancer Registry and census data of the years 1985, 1990, 1995 or 1997 of Statistics Finland. There were two data sets containing 46 312 and 12 542 people with cancer. The results showed that cancer survivors were slightly less often employed than their referents. Two to three years after the diagnosis the employment rate of the cancer survivors was 9% lower than that of their referents (64% vs. 73%), whereas the employment rate was the same before the diagnosis (78%). The employment rate varied greatly according to the cancer type and education. The probability of being employed was greater in the lower than in the higher educational groups. People with cancer were less often employed than people without cancer mainly because of their higher retirement rate (34% vs. 27%). As well as employment, retirement varied by cancer type. The risk of retirement was twofold for people having cancer of the nervous system or people with leukaemia compared to their referents, whereas people with skin cancer, for example, did not have an increased risk of retirement. The aim of the questionnaire study was to investigate whether the work ability of cancer survivors differs from that of people without cancer and whether cancer had impaired their work ability. There were 591 cancer survivors and 757 referents in the data. Even though current work ability of cancer survivors did not differ between the survivors and their referents, 26% of cancer survivors reported that their physical work ability, and 19% that their mental work ability had deteriorated due to cancer. The survivors who had other diseases or had had chemotherapy, most often reported impaired work ability, whereas survivors with a strong commitment to their work organization, or a good social climate at work, reported impairment less frequently. The aim of the other questionnaire study containing 640 people with the history of cancer was to examine extent of social support that cancer survivors needed, and had received from their work community. The cancer survivors had received most support from their co-workers, and they hoped for more support especially from the occupational health care personnel (39% of women and 29% of men). More support was especially needed by men who had lymphoma, had received chemotherapy or had a low education level. The results of this study show that the majority of the survivors are able to return to work. There is, however, a group of cancer survivors who leave work life early, have impaired work ability due to their illness, and suffer from lack of support from their work place and the occupational health services. Treatment-related, as well as sociodemographic factors play an important role in survivors' work-related problems, and presumably their possibilities to continue working.

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.
