Studying the diurnal and seasonal acclimation of photosystem Ii using chlorophyll-a fluorescence

A small fraction of the energy absorbed in the light reactions of photosynthesis is re-emitted as chlorophyll-a fluorescence. Chlorophyll-a fluorescence and photochemistry compete for excitation energy in photosystem II (PSII). Therefore, changes in the photochemical capacity can be detected through analysis of chlorophyll fluorescence. Chlorophyll fluorescence techniques have been widely used to follow the diurnal (fast), and the seasonal (slow) acclimation in the energy partitioning between photochemical and non-photochemical processes in PSII. Energy partitioning in PSII estimated through chlorophyll fluorescence can be used as a proxy of the plant physiological status, and measured at different spatial and temporal scales. However, a number of technical and theoretical limitations still limit the use of chlorophyll fluorescence data for the study of the acclimation of PSII. The aim of this Thesis was to study the diurnal and seasonal acclimation of PSII in field conditions through the development and testing of new chlorophyll fluorescence-based tools, overcoming these limitations. A new model capable of following the fast acclimation of PSII to rapid fluctuations in light intensity was developed. The model was used to study the rapid acclimation in the electron transport rate under fluctuating light. Additionally, new chlorophyll fluorescence parameters were developed for estimating the seasonal acclimation in the sustained rate constant of thermal energy dissipation and photochemistry. The parameters were used to quantitatively evaluate the effect of light and temperature on the seasonal acclimation of PSII. The results indicated that light environment not only affected the degree but also the kinetics of response of the acclimation to temperature, which was attributed to differences in the structural organization of PSII during seasonal acclimation. Furthermore, zeaxanthin-facilitated thermal dissipation appeared to be the main mechanisms modulating the fraction of absorbed energy being dissipated thermally during winter in field Scots pine. Finally, the integration between diurnal and seasonal acclimation mechanisms was studied using a recently developed instrument MONI-PAM (Walz GmbH, Germany) capable of continuously monitoring the energy partitioning in PSII.

Läksi puut ylenemähän : Metsien hoidon historia Suomessa keskiajalta metsäteollisuuden läpimurtoon 1870-luvulla

Tutkimuksen tavoitteena on historiantutkimuksen menetelmiä käyttäen selvittää metsänhoidon teorian sekä käytännön metsänhoidon kehitysvaiheet ja näihin vaikuttaneet tekijät, keskiajalta lähtien 1870-luvulla tapahtuneeseen metsäteollisuuden läpimurtoon saakka. Tutkimus tarkastelee Suomen metsiä, niiden käyttöä ja metsänhoidon alkuvaiheita Ruotsin ja Venäjän vallan aikoina. Vastauksia haetaan erityisesti seuraaviin pääkysymyksiin: - miten eri metsänkäyttömuodot ja -käyttäjät vaikuttivat metsiin ja metsänhoidon edistymiseen? - millä tavoin maanomistuksen kehitys vaikutti metsien käyttöön ja hoitoon? - millaisiin päämääriin ja yhteiskunnallisiin taustatekijöihin metsien käytön julkinen ohjaus perustui? - mitä käytännön vaikutuksia valtion metsäpolitiikalla ja ohjauksella oli metsänhoidon kehitykseen? - missä ja miten kehittyivät Suomessa sovellettu metsänhoidon teoria ja käytännön menetelmät? - mitkä tekijät säätelivät metsänhoidon teorioiden soveltamista käytäntöön? - mikä oli naapurimaiden metsänhoidon sekä kansainvälisten yhteyksien merkitys metsänhoidon kehitykselle Suomessa? - miten vuosisatainen pelko metsien ja puun loppumisesta vaikutti metsänhoidon kehitykseen? - millainen merkitys puun arvon kehityksellä oli metsänhoidon alkuun saattamiselle ja edistymiselle? Suomessa harjoitettiin 1870-luvulle saakka pääasiassa talonpoikaista metsänkäyttöä. Maaseudun väestö hankki toimeentulonsa metsistä eränkäynnin, kaskiviljelyn, laiduntamisen, rakennushirsien valmistamisen, tervantuotannon ja paikoin myös potaskan tai sysien valmistamisen avulla. Erityisesti rannikkoseuduilla tuotettiin "isorakennuksen puita", lehtereitä, mastopuita ja muuta erikoispuutavaraa. Lautojen ja lankkujen sahaus laajeni vähitellen, saavuttaen 1800-luvun lopulla hallitsevan aseman myyntiin tarkoitettujen metsäntuotteiden tuotannossa. Polttopuun sekä muun kotitarvepuun kulutus säilyi suurimpana puunkäytön ryhmänä pitkälle 1900-luvulle saakka. Mainituista metsänkäyttömuodoista erityisesti kaskeaminen ja sitä seuraava laiduntamisvaihe sekä tervaspuiden koloaminen "autioittivat" laajoja metsäalueita. Tiheimmin asutuilla seuduilla esiintyi pulaa poltto- ja rakennuspuusta myöhäiskeskiajalta alkaen. Nämä ongelmat sekä laivanrakennuksen ja vuoriteollisuuden puunsaannin turvaamisen tarve johtivat 1600-luvun puolivälissä pysyvään metsänkäytön julkiseen ohjaukseen. Tuolloin Ruotsin valtakunnan metsälainsäädännön kivijalaksi tuli kestävyyden periaate, josta kruunu kylläkin joutui tinkimään moneen otteeseen. Valtion jatkuva rahantarve oli käytännössä metsäpolitiikan tärkein taustavoima sekä Ruotsin vallan että autonomian aikana. Jo 1600-luvulla ruvettiin vaatimaan talonpoikien yhteismaiden jakamista omistajilleen vastuullisemman metsänkäytön nimissä. Isoajakoa saatiin Suomessa odottaa 1770-luvulle saakka. Etelä-Suomessa se valmistui melko nopeasti, 1800-luvun puoliväliin mennessä. Sillä olikin myönteinen, metsien säästävämpään käsittelyyn johtava vaikutus. Valtiosta tuli isonjaon myötä erityisesti Pohjois-Suomessa merkittävä metsänomistaja 1800-luvun jälkipuoliskolla. Valtion metsähallinto, jota maaherrat ja sivistyneistö vaativat perustettavaksi jo 1700-luvun puolivälissä, aloitti toimintansa maanlaajuisesti 1860-luvulla. Se oli ensimmäinen merkittävä metsänhoidon organisaatio, ja vasta sen myötä metsänkäyttöä ohjaavilla säädöksillä ja ohjeilla alkoi olla käytännön merkitystä. Yksityismetsiä varten ei tällaista organisaatiota vielä perustettu, niitä rasittivat pahoin nousevan sahateollisuuden määrämittahakkuut pitkälle 1900-luvun puolelle. Turun Akatemiassa tehtiin mittavaa metsänhoidon menetelmiä koskevaa sekä myös metsäpoliittista tutkimustyötä 1700-luvun jälkipuoliskolla. Tulokset eivät vielä sanottavasti siirtyneet käytäntöön, lähinnä puun alhaisen arvon ja tarvittavien organisaatioiden puuttumisen takia. Kun valtion metsähallintoa ja Suomen omaa metsäopetusta ryhdyttiin perustamaan 1800-luvun puolivälissä, haettiin metsänhoidon mallia alan johtavaksi maaksi kehittyneestä Saksasta. Tultaessa 1870-luvulle, oli Evolla jo käynnissä voimakas kehitystyö maamme olosuhteisiin soveltuvien menetelmien luomiseksi saksalaisen teorian pohjalta. Metsänhoidon tiedot ja taidot olisivat jo tässä vaiheessa riittäneet kestävän metsätalouden harjoittamiseen kaikkien omistajaryhmien metsissä, jos tarvittavat organisaatiot olisi kyetty perustamaan ja metsäammattilaisia olisi koulutettu tarpeeksi. Metsänhoidon kehitystä hidastivat 1800-luvun lopulla lähinnä valtion heikko talous ja poliittiset näkemyserot. Metsäteollisuuden 1870-luvulta alkanut voimakas kasvu ja lisääntyvä puuntarve pakottivat kuitenkin valtiovallan pitämään huolta puuntuotannon jatkuvuudesta. Metsäteollisuuden kasvavan viennin kautta lisääntyvät verotulot ja kan-santalouden myönteinen kehitys antoivat vähitellen mahdollisuuden metsänhoidon edistämiseen ammattilaisten koulutuksen, kansalaisten neuvonnan, lainsäädännön ja viranomaisten toiminnan kautta. Tämä tutkimus lähestyy aihettaan metsähistorian, taloushistorian, yhteiskuntahistorian ja ympäristöhistorian näkökulmista. Ajankohtaista merkitystä sillä on kehitysmaiden sekä Itä-Euroopan siirtymätalouksien metsänhoidon edistämiselle, missä suomalaiset metsäammattilaiset ovat mukana lukuisten kehityshankkeiden asiantuntijoina. Kymmenissä maissa metsätalous kamppailee samanlaisten ongelmien kanssa kuin Suomessa ja naapurimaissa 100 - 300 vuotta sitten. Meidän kokemuksistamme on näille kansantalouksille hyötyä valtion- ja yksityismetsätalouden metsänhoito-organisaatioita sekä metsälainsäädäntöä kehitettäessä.

Automatic Lameness Detection in a Milking Robot : Instrumentation, measurement software, algorithms for data analysis and a neural network model

The aim of this thesis is to develop a fully automatic lameness detection system that operates in a milking robot. The instrumentation, measurement software, algorithms for data analysis and a neural network model for lameness detection were developed. Automatic milking has become a common practice in dairy husbandry, and in the year 2006 about 4000 farms worldwide used over 6000 milking robots. There is a worldwide movement with the objective of fully automating every process from feeding to milking. Increase in automation is a consequence of increasing farm sizes, the demand for more efficient production and the growth of labour costs. As the level of automation increases, the time that the cattle keeper uses for monitoring animals often decreases. This has created a need for systems for automatically monitoring the health of farm animals. The popularity of milking robots also offers a new and unique possibility to monitor animals in a single confined space up to four times daily. Lameness is a crucial welfare issue in the modern dairy industry. Limb disorders cause serious welfare, health and economic problems especially in loose housing of cattle. Lameness causes losses in milk production and leads to early culling of animals. These costs could be reduced with early identification and treatment. At present, only a few methods for automatically detecting lameness have been developed, and the most common methods used for lameness detection and assessment are various visual locomotion scoring systems. The problem with locomotion scoring is that it needs experience to be conducted properly, it is labour intensive as an on-farm method and the results are subjective. A four balance system for measuring the leg load distribution of dairy cows during milking in order to detect lameness was developed and set up in the University of Helsinki Research farm Suitia. The leg weights of 73 cows were successfully recorded during almost 10,000 robotic milkings over a period of 5 months. The cows were locomotion scored weekly, and the lame cows were inspected clinically for hoof lesions. Unsuccessful measurements, caused by cows standing outside the balances, were removed from the data with a special algorithm, and the mean leg loads and the number of kicks during milking was calculated. In order to develop an expert system to automatically detect lameness cases, a model was needed. A probabilistic neural network (PNN) classifier model was chosen for the task. The data was divided in two parts and 5,074 measurements from 37 cows were used to train the model. The operation of the model was evaluated for its ability to detect lameness in the validating dataset, which had 4,868 measurements from 36 cows. The model was able to classify 96% of the measurements correctly as sound or lame cows, and 100% of the lameness cases in the validation data were identified. The number of measurements causing false alarms was 1.1%. The developed model has the potential to be used for on-farm decision support and can be used in a real-time lameness monitoring system.

Nutrition and Nutritional Care of Elderly People in Finnish Nursing Homes and Hospitals

Background: Malnutrition is a common problem for residents of nursing homes and long-term care hospitals. It has a negative influence on elderly residents and patients health and quality of life. Nutritional care seems to have a positive effect on elderly individuals nutritional status and well-being. Studies of Finnish elderly people s nutrition and nutritional care in institutions are scarce. Objectives: The primary aim was to investigate the nutritional status and its associated factors of elderly nursing home residents and long-term care patients in Finland. In particular, to find out, if the nursing or nutritional care factors are associated with the nutritional status, and how do carers and nurses recognize malnutrition. A further aim was to assess the energy and nutrient intake of the residents of dementia wards. A final objective was to find out, if the nutrition training of professionals leads to changes in their knowledge and further translate into better nutrition for the aged residents of dementia wards. Subjects and methods: The residents (n=2114) and patients (n=1043) nutritional status was assessed in all studies using the Mini Nutritional Assessment test (MNA). Information was gathered in a questionnaire on residents and patients daily routines providing nutritional care. Residents energy and nutrient intake (n=23; n=21) in dementia wards were determined over three days by the precise weighing method. Constructive learning theory was the basis for educating the professionals (n=28). A half-structured questionnaire was used to assess professionals learning. Studies I-IV were cross-sectional studies whereas study V was an intervention study. Results: Malnutrition was common among elderly residents and patients living in nursing homes and hospitals in Finland. According to the MNA, 11% to 57% of the studied elderly people suffered from malnutrition, and 40-89% were at risk of malnutrition, whereas only 0-16% had a good nutritional status. Resident- and patient-related factors such as dementia, impaired ADL (Activities of Daily Living), swallowing difficulties and constipation mainly explained the malnutrition, but also some nutritional care related factors, such as eating less than half of the offered food portion and not receiving snacks were also related to malnutrition. The intake of energy and some nutrients by the residents of dementia wards were lower than those recommended, although the offered food contained enough energy and nutrients. The proportion of residents receiving vitamin D supplementation was low, although there is a recommendation and known benefits for the adequate intake of vitamin D. Nurses recognized malnutrition poorly, only one in four (26.7%) of the actual cases. Keeping and analysing food diaries and reflecting on nutritional issues in small group discussions were effective training methods for professionals. The nutrition education of professionals had a positive impact on the energy and protein intake, BMIs, and the MNA scores of some residents in dementia wards. Conclusions: Malnutrition was common among elderly residents and patients living in nursing homes and hospitals in Finland. Although residents- and patient related factors mainly explained malnutrition, nurses recognized malnutrition poorly and nutritional care possibilities were in minor use. Professionals nutrition education had a positive impact on the nutrition of elderly residents. Further studies describing successful nutritional care and nutrition education of professionals are needed.

Rintamamiesten muonitus Suomessa sotavuosina 1939-1945

This study analyzes the war-time rations the Finnish soldiers received on the front from 1939 until 1945. The main objective was to determine the contents of the rations and how they affected the soldiers' nutrition and morale. The information concerning food and feeding is mainly based on the official documents found in the Military Archives. Some additional material was from the historical literature, some from memoirs, or from the veterans who personally experienced the front. The documents in the Archives of Military Medicine provided information on the soldiers' deficiencies. During the Winter War, which took place from 30 November 1939 until 13 March 1940, ample food was available. The cold climate caused problems and the fresh food got frozen. However, no severe deficiency cases were reported and the morale was high. By contrast, during the Continuation War, which began in June, 1941 and ended in September, 1944, difficulties were experienced. At the time farming in the country faced serious problems due to the shortage of labour, fuel, etc. Furthermore, importing food was generally not possible. However, importing food mainly from Germany saved the Finns from hunger. In addition, the self activity of the soldiers on the front added somewhat to the food production. But the rations had to be reduced. Their energy values were consequently low, especially for the young men. Food was monotonous and occasionally caused complaints. The main sources of protein, vitamins and minerals were the whole cereal foods. Butter was fortified with vitamin A and vitamin C tablets were also distributed, to compensate for the scant food sources. Only approximately 300 serious deficiency cases required hospital care during the three years time, out of a total of 400 000 soldiers. Feeding the young soldiers during the war (1944 - 1945) in Lapland, which had been destroyed, was problematic but the increased rations also saved them from deficiencies. In spite of the severe difficulties experienced occasionally in feeding the soldiers during the wars, the system worked all the time. The soldiers were fed, the cases of nutritional deficiency and epidemics caused by food were kept very limited and the morale of soldiers remained high.

The success of the diversified farm : resource-based view

Farms and rural areas have many specific valuable resources that can be used to create non-agricultural products and services. Most of the research regarding on-farm diversification has hitherto concentrated on business start-up or farm survival strategies. Resource allocation and also financial success have not been the primary focus of investigations as yet. In this study these specific topics were investigated i.e. resource allocation and also the financial success of diversified farms from a farm management perspective. The key question addressed in this dissertation, is how tangible and intangible resources of the diversified farm affect the financial success. This study’s theoretical background deals with resource-based theory, and also certain themes of the theory of learning organisation and other decision-making theories. Two datasets were utilised in this study. First, data were collected by postal survey in 2001 (n = 663). Second, data were collected in a follow-up survey in 2006 (n = 439). Data were analysed using multivariate data analyses and path analyses. The study results reveal that, diversified farms performed differently. Success and resources were linked. Professional and management skills affected other resources, and hence directly or indirectly influenced success per se. In the light of empirical analyses of this study, tangible and intangible resources owned by the diversified farm impacted on its financial success. The findings of this study underline the importance of skills and networks for entrepreneur(s). Practically speaking all respondents of this study used either agricultural resources for non-farm businesses or non-farm resources for agricultural enterprises. To share resources in this way was seen as a pragmatic opportunity recognised by farmers. One of the downsides of diversification might be the phenomenon of over-diversification, which can be defined as the situation in which a farm diversifies beyond its optimal limit. The empirical findings of this study reveal that capital and labour resource constrains did have adverse effects on financial success. The evidence indicates that farms that were capital and labour resource constrained in 2001 were still less profitable than their ‘no problems’ counterparts five years later.

Quality of ALICE SSD modules revealed by electrical tests

ALICE (A Large Ion Collider Experiment) is an experiment at CERN (European Organization for Nuclear Research), where a heavy-ion detector is dedicated to exploit the unique physics potential of nucleus-nucleus interactions at LHC (Large Hadron Collider) energies. In a part of that project, 716 so-called type V4 modules were assembles in Detector Laboratory of Helsinki Institute of Physics during the years 2004 - 2006. Altogether over a million detector strips has made this project the most massive particle detector project in the science history of Finland. One ALICE SSD module consists of a double-sided silicon sensor, two hybrids containing 12 HAL25 front end readout chips and some passive components, such has resistors and capacitors. The components are connected together by TAB (Tape Automated Bonding) microcables. The components of the modules were tested in every assembly phase with comparable electrical tests to ensure the reliable functioning of the detectors and to plot the possible problems. The components were accepted or rejected by the limits confirmed by ALICE collaboration. This study is concentrating on the test results of framed chips, hybrids and modules. The total yield of the framed chips is 90.8%, hybrids 96.1% and modules 86.2%. The individual test results have been investigated in the light of the known error sources that appeared during the project. After solving the problems appearing during the learning-curve of the project, the material problems, such as defected chip cables and sensors, seemed to induce the most of the assembly rejections. The problems were typically seen in tests as too many individual channel failures. Instead, the bonding failures rarely caused the rejections of any component. One sensor type among three different sensor manufacturers has proven to have lower quality than the others. The sensors of this manufacturer are very noisy and their depletion voltage are usually outside of the specification given to the manufacturers. Reaching 95% assembling yield during the module production demonstrates that the assembly process has been highly successful.

Properties of Ammonium Nitrate based fertilisers

The text is divided into three parts; Properties, Application and Safety of Ammonium Nitrate (AN) based fertilisers. In Properties, the structures and phase transitions of ammonium and potassium nitrate are reviewed. The consequences of phase transitions affect the proper use of fertilisers. Therefore the products must be stabilised against the volume changes and consequent loss of bulk density and hardness, formation of dust and finally caking of fertilisers. The effect of different stabilisers is discussed. Magnesium nitrate, ammonium sulphate and potassium nitrate are presented as a good compromise. In the Application part, the solid solutions in the systems (K+,NH4+)NO3- and (NH4+,K+)(Cl-,NO3-) are presented based on studies made with DSC and XRD. As there are clear limits for solute content in the solvent lattice, a number of disproportionation transitions exist in these process phases, e.g., N3 (solid solution isomorphous to NH4NO3-III) disproportionates to phases K3 (solid solution isomorphous to KNO3-III) and K2 (solid solution isomorphous to KNO3-II). In the crystallisation experiments, the formation of K3 depends upon temperature and the ratio K/(K+NH4). The formation of phases K3, N3, and K2 was modelled as a function of temperature and the mole ratios. In introducing chlorides, two distinct maxima for K3 were found. Confirmed with commercial potash samples, the variables affecting the reaction of potassium chloride with AN are the particle size, time, temperature, moisture content and amount of organic coating. The phase diagrams obtained by crystallisation studies were compared with a number of commercial fertilisers and, with regard to phase composition, the temperature and moisture content are critical when the formation and stability of solid solutions are considered. The temperature where the AN-based fertiliser is solidified affects the amount of compounds crystallised at that point. In addition, the temperature where the final moisture is evaporated affects the amount and type of solid solution formed at this temperature. The amount of remaining moisture affects the stability of the K3 phase. The K3 phase is dissolved by the moisture and recrystallised into the quantities of K3, which is stable at the temperature where the sample is kept. The remaining moisture should not be free; it should be bound as water in the final product. The temperatures during storage also affect the quantity of K3 phase. As presented in the figures, K3 phase is not stable at temperatu¬res below 30 °C. If the temperature is about 40 °C, the K3 phase can be formed due to the remaining moisture. In the Safety part, self-sustaining decomposition (SSD), oxidising and energetic properties of fertilisers are discussed. Based on the consequence analysis of SSD, early detection of decomposition in warehouses and proper temperature control in the manufacturing process is important. SSD and oxidising properties were found in compositions where K3 exists. It is assumed that potassium nitrate forms a solid matrix in which AN can decompose. The oxidising properties can be affected by the form of the product. Granular products are inherently less oxidising. Finally energetic properties are reviewed. The composition of the fertiliser has an importance based on theoretical calculations supported by experimental studies. Materials such as carbonates and sulphates act as diluents. An excess of ammonium ions acts as a fuel although this is debatable. Based on the experimental work, the physical properties have a major importance over the composition. A high bulk density is of key importance for detonation resistance.

TCP Performance in Heterogeneous Wireless Networks

The TCP protocol is used by most Internet applications today, including the recent mobile wireless terminals that use TCP for their World-Wide Web, E-mail and other traffic. The recent wireless network technologies, such as GPRS, are known to cause delay spikes in packet transfer. This causes unnecessary TCP retransmission timeouts. This dissertation proposes a mechanism, Forward RTO-Recovery (F-RTO) for detecting the unnecessary TCP retransmission timeouts and thus allow TCP to take appropriate follow-up actions. We analyze a Linux F-RTO implementation in various network scenarios and investigate different alternatives to the basic algorithm. The second part of this dissertation is focused on quickly adapting the TCP's transmission rate when the underlying link characteristics change suddenly. This can happen, for example, due to vertical hand-offs between GPRS and WLAN wireless technologies. We investigate the Quick-Start algorithm that, in collaboration with the network routers, aims to quickly probe the available bandwidth on a network path, and allow TCP's congestion control algorithms to use that information. By extensive simulations we study the different router algorithms and parameters for Quick-Start, and discuss the challenges Quick-Start faces in the current Internet. We also study the performance of Quick-Start when applied to vertical hand-offs between different wireless link technologies.

Förutsättningarna för psykiatrisk vård oberoende av patientens vilja och patientens rättsskydd vid fattandet av vårdbeslutet

I arbetet analyseras de i mentalvårdslagen (1990/1116) stadgade förutsättningarna för psykiatrisk sjukhusvård oberoende av patientens vilja gällande myndiga patienter för vilka inte har utsetts en intressebevakare före fattandet av vårdbeslutet, samt bakgrunden till och en del av de svårigheter som förknippas med denna form av vård och härtill anknutet beslutsfattande. Problemen tillspetsas framförallt i situationer av intressekonflikt mellan patientens intressen respektive samhällets intressen. Utgångspunkten ligger främst i finländsk mentalvårdslagstiftning och rättspraxis, men för att på ett ändamålsenligt sätt kunna redogöra för bakgrunden till och förutsättningarna för dylikt förvaltningsrättsligt beslutsfattande görs även relevanta kopplingar till medicinska (psykiatriska) yrkesetiska riktlinjer och mentalvårdslagstiftning inom övriga Norden. Analysen omfattar även den Europeiska människorättsdomstolens praxis i fall som gäller frihetsberövande på basis av psykiatrisk vård, närmare bestämt artikel 5 (1)(e) i den europeiska människorättskonventionen. Patientens självbestämmanderätt, frihet och integritet är utgångspunkterna för alla slags vårdförhållanden. Dessa inbegriper bl.a. frivillighet och informerat samtycke då en person söker vård. Möjligheten att förordna en person till psykiatrisk vård oberoende av dennes vilja är ett lagstadgat undantag till dessa principer. Beslutsfattandet är bundet till strikta lagstadgade förutsättningar, vilkas bedömning kräver juridisk, men framförallt medicinsk kunskap, vilket också skapar gränser och utmaningar för de yrkespersoner som arbetar med dylika ärenden. Kombinationen av psykiatri, etik och juridik är nödvändig, men inte alltid enkel att göra, vilket märks inte minst på terminologin som tillämpas i mentalvårdslagstiftningen. I arbetet analyseras en del av den terminologi som tillämpas inom finsk och övrig nordisk mentalvårdslagstiftning. Syftet är att visa att definitionerna, tolkningarna, terminologin och synsättet på psykisk ohälsa som tillämpas inom den finländska mentalvårdslagstiftningen jämförelsevis kanske inte är de mest lämpliga eller tidsenliga. En annan svår uppgift, som framförallt lagstiftaren ställ(t)s inför, är utformningen av mentalvårdslagstiftning som är tillräckligt flexibel för att tillåta beaktande av särdragen i varje enskilt ärende, men som samtidigt är strikt nog för att förhindra godtycke och missbruk. En person som lider av allvarlig psykisk ohälsa befinner sig oftast i en ytterst utsatt position, och är ofta begränsat eller inte alls kapabel att göra en korrekt bedömning av sig själv och sin situation. Således sker den starka betoningen av patientens självbestämmanderätt på både gott och ont. Det är kanske inte alltid i en psykiatrisk patients bästa att få bestämma själv, vilket också är en av frågorna som omfattas av analysen i arbetet. Eftersom det psykiatriska vårdbeslutet till karaktären är ett (skriftligt) förvaltningsbeslut, skiljer det sig samtidigt från övrigt beslutsfattande inom vårdsektorn, vilket till största delen utgör faktisk förvaltningsverksamhet. För patienten innebär vårdbeslutet också ett administrativt frihetsberövande. Ingreppet i patientens grundläggande fri- och rättigheter är särskilt stort och upplevs ofta som mycket kränkande, och därför ställs särskilt strikta krav på iakttagande av det lagstadgade beslutsförfarandet och vårdförutsättningarna samt tillgodoseendet av patientens rättsskydd. Den offentliga hälso- och sjukvården är verksamhet som är underställd den offentliga förvaltningen, vilket innebär att de allmänna förvaltningsrättsliga rättsskyddsgarantierna är tillämpliga. I och med vårdbeslutets karaktär av förvaltningsbeslut, kan ändring i beslutet sökas genom besvär hos förvaltningsdomstolen. Dessa är också några av de frågor som behandlas i arbetet.

The Mediated Immediacy : João Batista Libanio and the Question of Latin American Liberation Theology

This study is a systematic analysis of mediated immediacy in the production of the Brazilian professor of theology João Batista Libanio. He stresses both ethical mediation and the immediate character of the faith. Libanio has sought an answer to the problem of science and faith. He makes use of the neo-scholastic distinction between matter and form. According to St. Thomas Aquinas, God cannot be known as a scientific object, but it is possible to predicate a formal theological content of other subject matter with the help of revelation. This viewpoint was emphasized in neo-Thomism and supported by the liberation theologians. For them, the material starting point was social science. It becomes a theologizable or revealable (revelabile) reality. This social science has its roots in Latin American Marxism which was influenced by the school of Louis Althusser and considered Marxism a science of history . The synthesis of Thomism and Marxism is a challenge Libanio faced, especially in his Teologia da libertação from 1987. He emphasized the need for a genuinely spiritual and ethical discernment, and was particularly critical of the ethical implications of class struggle. Libanio s thinking has a strong hermeneutic flavor. It is more important to understand than to explain. He does not deny the need for social scientific data, but that they cannot be the exclusive starting point of theology. There are different readings of the world, both scientific and theological. A holistic understanding of the nature of religious experience is needed. Libanio follows the interpretation given by H. C. de Lima Vaz, according to whom the Hegelian dialectic is a rational circulation between the totality and its parts. He also recalls Oscar Cullmann s idea of God s Kingdom that is already and not yet . In other words, there is a continuous mediation of grace into the natural world. This dialectic is reflected in ethics. Faith must be verified in good works. Libanio uses the Thomist fides caritate formata principle and the modern orthopraxis thinking represented by Edward Schillebeeckx. One needs both the ortho of good faith and the praxis of the right action. The mediation of praxis is the mediation of human and divine love. Libanio s theology has strong roots in the Jesuit spirituality that places the emphasis on contemplation in action.

E. G. Gulinin ekumeeninen työ ja ajattelu

This study explores ecumenical activity of professor and bishop E. G. Gulin (1893 1975). Gulin was one of the key figures in the Finland s Evangelical Lutheran Church during the twentieth century. He was also one of the leading persons who imported ecumenical influences from abroad. However, unlike other churches, the Church of Finland did not recognise his importance. For example, in the 1950s Gulin was seen by the Anglicans as a future archbishop for the Evangelical Lutheran Church of Finland. Gulin s career as an ecumenist can be divided to three parts. Between 1917 and 1929, Gulin learned ecumenical working methods in Finland s World Student Christian Federation. He had a background in the revivalist movement, and his parents supported him in his studies. The Evangelical Lutheran Church did not originally play a major role for Gulin, although he was a member. Between 1930 and 1944, Gulin had more and more responsibility as a leading ecumenist in Finland. He became a member of Finland s ecumenical board, Yleiskirkollinen toimikunta. During the Second World War Gulin tried to solicit assistance for Finland s war effort at theological conferences, where Finnish theologians often discussed cooperation among Christians. A third period started in 1945, when Gulin became the bishop of Tampere. His new status in the Evangelical Lutheran Church placed him in a challenging position in ecumenical questions. He had responsibility for inter-church aid in Finland. He also participated in the World Council of Churches (WCC) assemblies in Evanston in 1954 and in New Delhi in 1961. Gulin s role was quite insignificant in those meetings. Closely related to Gulin s texts about ecumenism is kokemus, experience. Gulin wrote about his ecumenical experience or ekumeeninen kokemus. He believed that it was vital for the churches to appreciate their own experiences, since experience was the basis for further development. Yet Gulin mentioned very little about Christian dogma. The main reason seems to have been that he did not believe that a union between churches could be built on dogma.

Kirkko sydämessä : Uskonnon muokkautuminen ja individuaatio inkerinsuomalaisten elämänvaiheissa 1900-luvulla

The Church in one s heart. The formation of religion and individuation in the lives of Ingrian Finns in the 20th century. Sinikka Haapaniemi University of Helsinki, Finland 302 pages The study falls within the sphere of religious views and the problematique of the life trajectory. The target group comprises those Finnish speakers (Ingrian Finns, Ingrians) living in what was historically Ingermanland and who in varying circumstances became scattered. These times were characterized by pressures for change due to societal reasons and reasons of war. In conditions of change external living conditions matters of religious conviction may assume new meaning and form. The examination focuses on sustaining personal faith in difficult life situations and on how crises affected religious views. Another level of scrutiny takes shape through the terminology of the analytic psychology of C.G. Jung. Individuation is deemed to occur as a cumulative process through the stages of life. The basic data for the study comprises interviews with twenty (20) natives of Ingria and their biographical narratives written in standard language. Many biographical accounts and memoirs serve as secondary data. The interviewees, who were largely selected at random, recounted their lives without questions formulated in advance. The study falls within the field of comparative religion and adheres to the principles of qualitative research practice and the case-study method. Effort was made to get to know each interviewee in the situation which his/her narrative presents. The aim is to pay attention to the interpretations given by the narrators of their various experiences and to understand their meanings on a personal level. The years during which the Ingrians were scattered, wandering and returning raise problems of survival. An individual s own initiative assumes individual forms and emphases. Religion was part of the narrators lives as one factor in the quality of life. Their religious thinking was influenced by both their home upbringing and the teaching of the Church. The interviewees took a serious attitude to the informative teaching of confirmation training. When there was no longer a church, it was claimed that the church travelled with them. Changed circumstances tested the validity of the teachings. The message of the Church institution persisted and helped them to preserve their traditions. A striving for unity and for the presence of a community emerged both in the form of ritual behaviour and in a predilection to sociability. Gradually, as they returned, the activity of the Church of Ingria began to revive. At the turn of the millennium the network of parishes was extensive and cultural activity flourished wherever the Ingrians settled in the postwar decades. Religion is part of the process of individuation. Examination of religion and individuation shows that religion remained an individual view, whose factual base was formed by Christianity and the tradition of the Church. Home upbringing served to orientate, but not to bind. With ageing the importance of independent thought is emphasized, for example in relation to confession, it did not pose a threat to individuality.

Pimeä hehku : Satanismi ja saatananpalvonta 1990-luvun suomalaisessa nuorisokulttuurissa

Satanism in the Finnish Youth Culture of the 1990s The aim of this study was to investigate Satanism among Finnish youth in the 1990s. Thematic interviews of young Finnish Satanists are the basic material of this study. The research employs a theoretical framework derived from narrative psychology and the role-theoretical thinking of Dan P. McAdams. The young Satanists in Finland have been divided into two different groups: the criminal and drug using "devil-worshipping gangs"; and the more educated and philosophically oriented "Satanists" (Heino 1993). What can we say about this division? In the 1990s around Finland, there were young people calling themselves as devil- worshippers (either singular or in groups). They were strongly committed to a mythical devilish and cosmic battle, which they believed was going on in this world. They had problems with their mental health, also in their family socialization and peer groups. In their personal attitudes they were either active fighters or passive tramps. There were also rationally oriented young Satanists, that were ritually active and mainly atheistic. They strongly expressed their personal experiences of being individual and of being different than others. In their personal attitudes they were critical fighters and active survivors. They saw their lives through the satanistic 'finding-oneself experience'. They understood themselves as a "postmodern tribe" (Michel Maffesoli's sosiocultural concept): their sense of themselves was that of a dynamic collectivity which is social, dynamic, nonlocal and mythically historical. Death and black metal culture in the 1990s formed a common space for youth culture, where young individuals could work out their feelings and express their attitudes to life using dark satanic themes and symbols. The sense of "otherness" (also other than satanic) and collective demands for authenticity were essential tools that were used for identity work here. Personal disengagement from satanic/satanistic groups were observed to be gradual or quite rapid. Religious conversions back-and-forth also accured. At the end of the 1990s all off satanism in Finland bore a negative devil-worshipping stigma. Ritual homicide in South-Finland (Kerava/Hyvinkää) was connected to Satanism, which then became unpopular both in the personal life stories and alternative youth cultural circles at the beginning of the 2000s.
