But if you desire God and His Messenger : The concept of choice in Sahih al-Bukhari

The aim of this dissertation is to discuss the concept of choice in the most important collection of Islamic traditions, Sahih al-Bukhari. The author of the collection, Muhammad ibn Isma'il al-Bukhari, lived between 810-870. My starting point is the collection of texts as it is now in its normative, established form. I read the hadiths as pieces of reality, not as statements about reality. The historicity of the texts has no role at all in my analysis. Part I sketches out the hagiography of the life and work of the author and provides a short history of the development of hadith literature and the processes of collecting and classifying the texts are discussed briefly. Part one ends with the presentation of my way of using rhetorical analysis as a methodological tool. Part II introduces my analysis of the concept of choice. It is divided into ten chapters, each concentrating on one hadith cluster. Part II ends with a discussion of the philosophy of free will and predestination in early Islam. Hadith literature is often considered as a representative of predestinarian theology compared to the Qur'an which emphasises the reponsibility of people of their own acts. In my conclusions I suggest that accoding to the texts in Sahih al-Bukhari, people do deal with real choices in their lives. The collection includes both strictly predestinarian texts but it also compises texts which claim that people are demanded to make real choices, even choices concerning life and death.

Zur Sättigung der Valenz in den Kleinen Meldungen des Typus Notiz : Eine pragmatisch fundierte Analyse

Valency Realization in Short Excerpts of News Text. A Pragmatics-funded analysis This dissertation is a study of the so-called pragmatic valency. The aim of the study is to examine the phenomenon both theoretically by discussing the research literature and empirically based on evidence from a text corpus consisting of 218 short excerpts of news text from the German newspaper Frankfurter Allgemeine Zeitung. In the theoretical part of the study, the central concepts of the valency and the pragmatic valency are discussed. In the research literature, the valency denotes the relation among the verb and its obligatory and optional complements. The pragmatic valency can be defined as modification of the so-called system valency in the parole, including non-realization of an obligatory complement, non- realization of an optional complement and realization of an optional complement. Furthermore, the investigation of the pragmatic valency includes the role of the adjuncts, elements that are not defined by the valency, in the concrete valency realization. The corpus study investigates the valency behaviour of German verbs in a corpus of about 1500 sentences combining the methodology and concepts of valency theory, semantics and text linguistics. The analysis is focused on the about 600 sentences which show deviations from the system valency, providing over 800 examples for the modification of the system valency as codified in the (valency) dictionaries. The study attempts to answer the following primary question: Why is the system valency modified in the parole? To answer the question, the concept of modification types is entered. The modification types are recognized using distinctive feature bundles in which each feature with a negative or a positive value refers to one reason for the modification treated in the research literature. For example, the features of irrelevance and relevance, focus, world and text type knowledge, text theme, theme-rheme structure and cohesive chains are applied. The valency approach appears in a new light when explored through corpus-based investigation; both the optionality of complements and the distinction between complements and adjuncts as defined in the present valency approach seem in some respects defective. Furthermore, the analysis indicates that the adjuncts outside the valency domain play a central role in the concrete realization of the valency. Finally, the study suggests a definition of pragmatic valency, based on the modification types introduced in the study and tested in the corpus analysis.

Problems of Proto-Slavic Historical Nominal Morphology : On the Basis of Old Church Slavic

In this study I offer a diachronic solution for a number of difficult inflectional endings in Old Church Slavic nominal declensions. In this context I address the perhaps most disputed and the most important question of the Slavic nominal inflectional morphology: whether there was in Proto-Slavic an Auslautgesetz (ALG), a law of final syllables, that narrowed the Proto-Indo-European vowel */o/ to */u/ in closed word-final syllables. In addition, the work contains an exhaustive morphological classification of the nouns and adjectives that occur in canonical Old Church Slavic. I argue that Proto-Indo-European */o/ became Proto-Slavic */u/ before word-final */s/ and */N/. This conclusion is based on the impossibility of finding credible analogical (as opposed to phonological) explanations for the forms supporting the ALG hypothesis, and on the survival of the neuter gender in Slavic. It is not likely that the */o/-stem nominative singular ending */-u/ was borrowed from the accusative singular, because the latter would have been the only paradigmatic form with the stem vowel */-u-/. It is equally unlikely that the ending */-u/ was borrowed from the */u/-stems, because the latter constituted a moribund class. The usually stated motivation for such an analogical borrowing, i.e. a need to prevent the merger of */o/-stem masculines with neuters of the same class, is not tenable. Extra-Slavic, as well as intra-Slavic evidence suggests that phonologically-triggered mergers between two semantically opaque genders do not tend to be prevented, but rather that such mergers lead to the loss of the gender opposition in question. On the other hand, if */-os/ had not become */-us/, most nouns and, most importantly, all adjectives and pronouns would have lost the formal distinction between masculines and neuters. This would have necessarily resulted in the loss of the neuter gender. A new explanation is given for the most apparent piece of evidence against the ALG hypothesis, the nominative-accusative singular of the */es/-stem neuters, e.g. nebo 'sky'. I argue that it arose in late Proto-Slavic dialects, replacing regular nebe, under the influence of the */o/- and */yo/-stems where a correlation had emerged between a hard root-final consonant and the termination -o, on the one hand, and a soft root-final consonant and the termination -e, on the other.

Between Herbals et alia: Intertextuality in Medieval English Herbals

This study reports a corpus-based study of medieval English herbals, which are texts conveying information on medicinal plants. Herbals belong to the medieval medical register. The study charts intertextual parallels within the medieval genre, and between herbals and other contemporary medical texts. It seeks to answer questions where and how herbal texts are linked to each other, and to other medical writing. The theoretical framework of the study draws on intertextuality and genre studies, manuscript studies, corpus linguistics, and multi-dimensional text analysis. The method combines qualitative and quantitative analyses of textual material from three historical special-language corpora of Middle and Early Modern English, one of which was compiled for the purposes of this study. The text material contains over 800,000 words of medical texts. The time span of the material is from c. 1330 to 1550. Text material is retrieved from the corpora by using plant name lists as search criteria. The raw data is filtered through qualitative analysis which produces input for the quantitative analysis, multi-dimensional scaling (MDS). In MDS, the textual space that parallel text passages form is observed, and the observations are explained by a qualitative analysis. This study concentrates on evidence of material and structural intertextuality. The analysis shows patterns of affinity between the texts of the herbal genre, and between herbals and other texts in the medical register. Herbals are most closely linked with recipe collections and regimens of health: they comprise over 95 per cent of the intertextual links between herbals and other medical writing. Links to surgical texts, or to specialised medical texts are very few. This can be explained by the history of the herbal genre: as herbals carry information on medical ingredients, herbs, they are relevant for genres that are related to pharmacological therapy. Conversely, herbals draw material from recipe collections in order to illustrate the medicinal properties of the herbs they describe. The study points out the close relationship between medical recipes and recipe-like passages in herbals (recipe paraphrases). The examples of recipe paraphrases show that they may have been perceived as indirect instruction.

Vankina valkoisten : Oulun vankileiri 1918

Suomen sisällissodassa keväällä vuonna 1918 syntyi useita vankileirejä, jotka oli tarkoitettu valkoisten vangitsemia punaisia varten. Yksi vankileireistä sijaitsi Oulun Raatinsaaressa. Tässä tutkimuksessa olen tarkastellut Oulun vankileirin vankeja, vartijoita ja leirin oloja sekä valtiorikosoikeuden toimintaa ja leirin kuolleisuutta. Oulun vankileiri toimi Valloitettujen alueiden turvaamisosastoon kuuluneen sotavankilaitoksen alaisuudessa. Vankileiri oli tarkoitettu lähinnä Oulun ja Lapin läänin punavankeja varten. Myös asevelvollisuuskutsuntoja vältelleitä ja asevelvollisuudesta kieltäytyneitä oli vangittujen joukossa. Vankien määrä oli suurimmillaan hieman yli 800. Vangit kuuluivat pääsääntöisesti työväenluokkaan. Vangittuina oli myös naisia, joista suurin osa oli pidätetty venäläisten kasarmeilta. Venäläisiä sotilaita, joita oli noin 1000, pidettiin vangittuina omilla kasarmeillaan, ennen kuin heidät kotiutettiin toukokuun lopussa. Vartijoina toimivat aluksi Oulun ja lähikuntien suojeluskuntajoukot ja toukokuun lopusta lähtien asevelvollisuusjoukot. Erityisesti asevelvollisjoukkoja pidettiin vartiointitehtävään sopimattomina. Sotilaat suhtautuivat tehtäviinsä välinpitämättömästi ja vankeihin myötämielisesti. Heistä suurin osa oli kotoisin samoilta paikkakunnilta, mistä punavangitkin ja he kuuluivat suurimmalta osaltaan myös työväenluokkaan. Asevelvollisjoukot olivat myös ylityöllistettyjä ja sotilaskuri oli olematonta, joten ei ollut ihme, että heinäkuun alussa useat asevelvollissotilaat karkasivat riveistä. Vangit asuivat leirillä ahtaasti ja saivat vain niukasti ruokaa. Leirillä vankeja hoitivat lääkäri ja kaksi sairaanhoitajaa. Sairaanhoito oli hankalaa, koska sairastuneita ja heikkoja vankeja oli paljon. Vankien hengellisestä huollosta oli vastuussa kasvatusosasto, jonka johdossa oli pappi apunaan kaksi kasvatusapulaista. Kesäkuun aikana Oulussa toimintansa aloitti kaksi valtiorikosoikeuden osastoa, jotka langettivat tuomioita samanlaisen linjan mukaisesti kuin muuallakin maassa. Punaisena lankana näyttää olleen työväenliikkeen poliittinen nujertaminen. Kuolleisuuden suhteelliseen alhaisuuteen oli osasyynä se, että vartijat eivät olleet kiinnostuneita tehtäviään kohtaan. He eivät estäneet yhteydenpitoa vankien ja heidän omaistensa välillä. Vartijat eivät myöskään syyllistyneet vankileiriterroriin, vaan suhtautuivat vankeja kohtaan pääsääntöisesti maltillisesti. Vangeilla oli mahdollisuuksia ulkopuoliseen ruoansaantiin omaisten kautta ja työskennellessään leirin ulkopuolella eri työtehtävissä. Vankeja käytettiinkin vankileirin ulkopuolisiin työtehtäviin paljon. Koska työnantajat oli velvoitettu kustantamaan työssäkäyvien vankien ruoan, he saivat lisäravintoa ohi vankileiriorganisaation. Siten vangit olivat tarpeeksi vastustuskykyisiä tarttuvia tauteja kohtaan. Oulun vankileirissä kuolleisuus jäikin suhteellisen alhaiseksi hieman alle kuuteen prosenttiin.

Kuvan ja tekstin välissä : Kuvateksti uutiskuvan ja lehtijutun elementtinä

The study focuses on picture captions: their grammar and interplay with photographs and their position as semi-independent elements of the news stories. The research was conducted in the framework of critical discourse analysis, social semiotic visual theory and fennistic syntactical research. The data consist of 441 press photographs, 1,815 captions and a number of news items from Finnish dailies. The generic structure potential of the caption includes the caption headline, the caption proper, i.e. the verbalization of the picture content, and the frame. In the data, 41 per cent of the captions have a headline, and 44 per cent contain a caption proper. Characteristic of the caption proper is omission of the finite verb and the use of the present tense, both of which have decreased in Finnish papers during the 20th century. The caption proper is typically a main clause, and both subordinate clauses and participal phrases occur mostly in the frame. While comparing caption variants attached to the same pictures, the processes and their participants proved to be identified considerably identically, following the news agency captions. Instead, the reader?s interpretations of a picture could be directed by framing it in different ways. For example, the caption may focus on the only person depicted, deal with a whole group, or give an abstract account of the situation. The caption is a paratext, a typographically marked, semi-independent element of a news story. Between the headline and the caption, four semantic relations have been identified. The caption may be a paraphrase of the headline, or a close-up illustrating an abstract headline with a concrete example. If the name of the person depicted is their only common factor, the relation between the caption and the headline is additive. A specifying caption will give more details than the headline. The caption may complete, repeat, or summarize the body copy. Naturally, most captions completing the story verbalize the content of the picture. As the caption is often based on the story, it may even repeat the body copy verbatim. The summarizing function is probably becoming increasingly important, as most Finnish newspapers have abandoned the use of a separate standfirst.

Is a Majority Enough? Psychological Well-being and Its Relation to Academic and Prosocial Motivation, Self-regulation and Achievement at school

This cross-sectional study analyzed psychological well-being at school using the Self-Determination theory as a theoretical frame-work. The study explored basic psychological needs fulfillment (BPNS), academic (SRQ-A), prosocial self-regulation (SRQ-P) and motivation, and their relationship with achievement in general, special and selective education (N=786, 444 boys, 345 girls, mean age 12 yrs 8 mths). Motivation starts behavior which becomes guided by self-regulation. The perceived locus of control (PLOC) affects how self-determined this behavior will be; in other words, to what extent it is autonomously regulated. In order learn and thus to be able to accept external goals, a student has to feel emotionally safe and have sufficient ego-flexibility—all of which builds on satisfied psychological needs. In this study those conditions were explored. In addition to traditional methods Self-organizing maps (SOM), was used in order to cluster the students according to their well-being, self-regulation, motivation and achievement scores. The main impacts of this research were: a presentation of the theory based alternative of studying psychological well-being at school and usage of both the variable and person-oriented approach. In this Finnish sample the results showed that the majority of students felt well, but the well-being varied by group. Overall about for 11–15% the basic needs were deprived depending on the educational group. Age and educational group were the most effective factors; gender was important in relation to prosocial identified behavior. Although the person-oriented SOM-approach, was in a large extent confirming what was no-ticed by using comparison of the variables: the SEN groups had lower levels of basic needs fulfillment and less autonomous self-regulation, interesting deviations of that rule appeared. Some of the SEL- and GEN-group members ended up in the more unfavorable SOM-clusters, and not all SEN-group members belonged to the poorest clusters (although not to the best either). This evidence refines the well-being and self-regulation picture, and may re-direct intervention plans, and turn our focus also on students who might otherwise remain unnoticed. On the other hand, these results imply simultaneously that in special education groups the average is not the whole truth. On the basis of theoretical and empirical considerations an intervention model was sug-gested. The aim of the model was to shift amotivation or external motivation in a more intrinsic direction. According to the theoretical and empirical evidence this can be achieved first by studying the self-concept a student has, and then trying to affect both inner and environmental factors—including a consideration of the basic psychological needs.

Perspectives on prescribing in nursing homes in Helsinki

Prescribing for older patients is challenging. The prevalence of diseases increases with advancing age and causes extensive drug use. Impairments in cognitive, sensory, social and physical functioning, multimorbidity and comorbidities, as well as age-related changes in pharmacokinetics and pharmacodynamics all add to the complexity of prescribing. This study is a cross-sectional assessment of all long-term residents aged ≥ 65 years in all nursing homes in Helsinki, Finland. The residents’ health status was assessed and data on their demographic factors, health and medications were collected from their medical records in February 2003. This study assesses some essential issues in prescribing for older people: psychotropic drugs (Paper I), laxatives (Paper II), vitamin D and calcium supplements (Paper III), potentially inappropriate drugs for older adults (PIDs) and drug-drug interactions (DDIs)(Paper IV), as well as prescribing in public and private nursing homes. A resident was classified as a medication user if his or her medication record indicated a regular sequence for its dosage. Others were classified as non-users. Mini Nutritional Assessment (MNA) was used to assess residents’ nutritional status, Beers 2003 criteria to assess the use of PIDs, and the Swedish, Finnish, INteraction X-referencing database (SFINX) to evaluate their exposure to DDIs. Of all nursing home residents in Helsinki, 82% (n=1987) participated in studies I, II, and IV and 87% (n=2114) participated in the study III. The residents’ mean age was 84 years, 81% were female, and 70% were diagnosed with dementia. The mean number of drugs was 7.9 per resident; 40% of the residents used ≥ 9 drugs per day, and were thus exposed to polypharmacy. Eighty percent of the residents received psychotropics; 43% received antipsychotics, and 45% used antidepressants. Anxiolytics were prescribed to 26%, and hypnotics to 28% of the residents. Of those residents diagnosed with dementia, 11% received antidementia drugs. Fifty five percent of the residents used laxatives regularly. In multivariate analysis, those factors associated with regular laxative use were advanced age, immobility, poor nutritional status, chewing problems, Parkinson’s disease, and a high number of drugs. Eating snacks between meals was associated with lower risk for laxative use. Of all participants, 33% received vitamin D supplementation, 28% received calcium supplementation, and 20% received both vitamin D and calcium. The dosage of vitamin D was rather low: 21% received vitamin D 400 IU (10 µg) or more, and only 4% received 800 IU (20 µg) or more. In multivariate analysis, residents who received vitamin D supplementation enjoyed better nutritional status, ate snacks between meals, suffered no constipation, and received regular weight monitoring. Those residents receiving PIDs (34% of all residents) more often used psychotropic medication and were more often exposed to polypharmacy than residents receiving no PIDs. Residents receiving PIDs were less often diagnosed with dementia than were residents receiving no PIDs. The three most prevalent PIDs were short-acting benzodiazepine in greater dosages than recommended, hydroxyzine, and nitrofurantoin. These three drugs accounted for nearly 77% of all PID use. Of all residents, less than 5% were susceptible to a clinically significant DDI. The most common DDIs were related to the use of potassium-sparing diuretics, carbamazepine, and codeine. Residents exposed to potential DDIs were younger, had more often suffered a previous stroke, more often used psychotropics, and were more often exposed to PIDs and polypharmacy than were residents not exposed to DDIs. Residents in private nursing homes were less often exposed to polypharmacy than were residents in public nursing homes. Long-term residents in nursing homes in Helsinki use, on average, nearly eight drugs daily. The use of psychotropic drugs in our study was notably more common than in international studies. The prevalence of laxatives equaled other prior international studies. Regardless of the known benefit and recommendation of vitamin D supplementation for elderly residing mostly indoors, the proportion of nursing home residents receiving vitamin D and calcium was surprisingly low. The use of PIDs was common among nursing home residents. PIDs increased the likelihood of DDIs. However, DDIs did not seem a major concern among the nursing home population. Monitoring PIDs and potential drug interactions could improve the quality of prescribing.

Genetic basis of hereditary colorectal cancers: Hereditary nonpolyposis colorectal cancer and Familial adenomatous polyposis

Hereditary nonpolyposis colorectal cancer (HNPCC) and familial adenomatous polyposis (FAP) are characterized by a high risk and early onset of colorectal cancer (CRC). HNPCC is due to a germline mutation in one of the following MMR genes: MLH1, MSH2, MSH6 and PMS2. A majority of FAP and attenuated FAP (AFAP) cases are due to germline mutations of APC, causing the development of multiple colorectal polyps. To date, over 450 MMR gene mutations and over 800 APC mutations have been identified. Most of these mutations lead to a truncated protein, easily detected by conventional mutation detection methods. However, in about 30% of HNPCC and FAP, and about 90% of AFAP families, mutations remain unknown. We aimed to clarify the genetic basis and genotype-phenotype correlation of mutation negative HNPCC and FAP/AFAP families by advanced mutation detection methods designed to detect large genomic rearrangements, mRNA and protein expression alterations, promoter mutations, phenotype linked haplotypes, and tumoral loss of heterozygosity. We also aimed to estimate the frequency of HNPCC in Uruguayan CRC patients. Our expression based analysis of mutation negative HNPCC divided these families into two categories: 1) 42% of families linked to the MMR genes with a phenotype resembling that of mutation positive, and 2) 58% of families likely to be associated with other susceptibility genes. Unbalanced mRNA expression of MLH1 was observed in two families. Further studies revealed that a MLH1 nonsense mutation, R100X was associated with aberrant splicing of exons not related to the mutation and an MLH1 deletion (AGAA) at nucleotide 210 was associated with multiple exon skipping, without an overall increase in the frequency of splice events. APC mutation negative FAP/AFAP families were divided into four groups according to the genetic basis of their predisposition. Four (14%) families displayed a constitutional deletion of APC with profuse polyposis, early age of onset and frequent extracolonic manifestations. Aberrant mRNA expression of one allele was observed in seven (24%) families with later onset and less frequent extracolonic manifestations. In 15 (52%) families the involvement of APC could neither be confirmed nor excluded. In three (10%) of the families a germline mutation was detected in genes other than APC: AXIN2 in one family, and MYH in two families. The families with undefined genetic basis and especially those with AXIN2 or MYH mutations frequently displayed AFAP or atypical polyposis. Of the Uruguayan CRC patients, 2.6% (12/461) fulfilled the diagnostic criteria for HNPCC and 5.6% (26/461) were associated with increased risk of cancer. Unexpectedly low frequency of molecularly defined HNPCC cases may suggest a different genetic profile in the Uruguayan population and the involvement of novel susceptibility genes. Accurate genetic and clinical characterization of families with hereditary colorectal cancers, and the definition of the genetic basis of "mutation negative" families in particular, facilitate proper clinical management of such families.

Effects of dietary phosphorus and calcium-to-phosphorus ratio on calcium and bone metabolism in healthy 20- to 43-year-old Finnish women

Dietary habits have changed during the past decades towards an increasing consumption of processed foods, which has notably increased not only total dietary phosphorus (P) intake, but also intake of P from phosphate additives. While the intake of calcium (Ca) in many Western countries remains below recommended levels (800 mg/d), the usual daily P intake in a typical Western diet exceeds by 2- to 3-fold the dietary guidelines (600 mg/d). The effects of high P intake in healthy humans have been investigated seldom. In this thesis healthy 20- to 43-year-old women were studied. In the first controlled study (n = 14), we examined the effects of P doses, and in a cross-sectional study (n = 147) the associations of habitual P intakes with Ca and bone metabolism. In this same cross-sectional study, we also investigated whether differences exist between dietary P originating from natural P sources and phosphate additives. The second controlled study (n = 12) investigated whether by increasing the Ca intake, the effects of a high P intake could be reduced. The associations of habitual dietary calcium-to-phosphorus ratios (Ca:P ratio) with Ca and bone metabolism were determined in a cross-sectional study design (n = 147). In the controlled study, the oral intake of P doses (495, 745, 1245 and 1995 mg/d) with a low Ca intake (250 mg/d) increased serum parathyroid hormone (S-PTH) concentration in a dose-dependent manner. In addition, the highest P dose decreased serum ionized calcium (S-iCa) concentration and bone formation and increased bone resorption. In the second controlled study with a dietary P intake of 1850 mg/d, by increasing the Ca intake from 480 mg/d to 1080 mg/d and then to 1680 mg/d, the S-PTH concentration decreased, the S-iCa concentration increased and bone resorption decreased dose-dependently. However, not even the highest Ca intake could counteract the effect of high dietary P on bone formation, as indicated by unchanged bone formation activity. In the cross-sectional studies, a higher habitual dietary P intake (>1650 mg/d) was associated with lower S-iCa and higher S-PTH concentrations. The consumption of phosphate additive-containing foods was associated with a higher S-PTH concentration. Moreover, habitual low dietary Ca:P ratios (≤0.50, molar ratio) were associated with higher S-PTH concentrations and 24-h urinary Ca excretions, suggesting that low dietary Ca:P ratios may interfere with homeostasis of Ca metabolism and increase bone resorption. In summary, excessive dietary P intake in healthy Finnish women seems to be detrimental to Ca and bone metabolism, especially when dietary Ca intake is low. The results indicate that by increasing dietary Ca intake to the recommended level, the negative effects of high P intake could be diminished, but not totally prevented. These findings imply that phosphate additives may be more harmful than natural P. Thus, reduction of an excessively high dietary P intake is also beneficial for healthy individuals.

Spatial and temporal variability in midge (Nematocera) assemblages in shallow Finnish lakes (60−70 °N) : community-based modelling of past environmental change

Multi- and intralake datasets of fossil midge assemblages in surface sediments of small shallow lakes in Finland were studied to determine the most important environmental factors explaining trends in midge distribution and abundance. The aim was to develop palaeoenvironmental calibration models for the most important environmental variables for the purpose of reconstructing past environmental conditions. The developed models were applied to three high-resolution fossil midge stratigraphies from southern and eastern Finland to interpret environmental variability over the past 2000 years, with special focus on the Medieval Climate Anomaly (MCA), the Little Ice Age (LIA) and recent anthropogenic changes. The midge-based results were compared with physical properties of the sediment, historical evidence and environmental reconstructions based on diatoms (Bacillariophyta), cladocerans (Crustacea: Cladocera) and tree rings. The results showed that the most important environmental factor controlling midge distribution and abundance along a latitudinal gradient in Finland was the mean July air temperature (TJul). However, when the dataset was environmentally screened to include only pristine lakes, water depth at the sampling site became more important. Furthermore, when the dataset was geographically scaled to southern Finland, hypolimnetic oxygen conditions became the dominant environmental factor. The results from an intralake dataset from eastern Finland showed that the most important environmental factors controlling midge distribution within a lake basin were river contribution, water depth and submerged vegetation patterns. In addition, the results of the intralake dataset showed that the fossil midge assemblages represent fauna that lived in close proximity to the sampling sites, thus enabling the exploration of within-lake gradients in midge assemblages. Importantly, this within-lake heterogeneity in midge assemblages may have effects on midge-based temperature estimations, because samples taken from the deepest point of a lake basin may infer considerably colder temperatures than expected, as shown by the present test results. Therefore, it is suggested here that the samples in fossil midge studies involving shallow boreal lakes should be taken from the sublittoral, where the assemblages are most representative of the whole lake fauna. Transfer functions between midge assemblages and the environmental forcing factors that were significantly related with the assemblages, including mean air TJul, water depth, hypolimnetic oxygen, stream flow and distance to littoral vegetation, were developed using weighted averaging (WA) and weighted averaging-partial least squares (WA-PLS) techniques, which outperformed all the other tested numerical approaches. Application of the models in downcore studies showed mostly consistent trends. Based on the present results, which agreed with previous studies and historical evidence, the Medieval Climate Anomaly between ca. 800 and 1300 AD in eastern Finland was characterized by warm temperature conditions and dry summers, but probably humid winters. The Little Ice Age (LIA) prevailed in southern Finland from ca. 1550 to 1850 AD, with the coldest conditions occurring at ca. 1700 AD, whereas in eastern Finland the cold conditions prevailed over a longer time period, from ca. 1300 until 1900 AD. The recent climatic warming was clearly represented in all of the temperature reconstructions. In the terms of long-term climatology, the present results provide support for the concept that the North Atlantic Oscillation (NAO) index has a positive correlation with winter precipitation and annual temperature and a negative correlation with summer precipitation in eastern Finland. In general, the results indicate a relatively warm climate with dry summers but snowy winters during the MCA and a cool climate with rainy summers and dry winters during the LIA. The results of the present reconstructions and the forthcoming applications of the models can be used in assessments of long-term environmental dynamics to refine the understanding of past environmental reference conditions and natural variability required by environmental scientists, ecologists and policy makers to make decisions concerning the presently occurring global, regional and local changes. The developed midge-based models for temperature, hypolimnetic oxygen, water depth, littoral vegetation shift and stream flow, presented in this thesis, are open for scientific use on request.

Environmental change and anthropogenic impact on lake sediments during the Holocene in the Finnish - Karelian inland area

This thesis discusses the prehistoric human disturbance during the Holocene by means of case studies using detailed high-resolution pollen analysis from lake sediment. The four lakes studied are situated between 61o 40' and 61o 50' latitudes in the Finnish Karelian inland area and vary between 2.4 and 28.8 ha in size. The existence of Early Metal Age population was one important question. Another study question concerned the development of grazing, and the relationship between slash-and-burn cultivation and permanent field cultivation. The results were presented as pollen percentages and pollen concentrations (grains cm 3). Accumulation values (grains cm 2 yr 1) were calculated for Lake Nautajärvi and Lake Orijärvi sediment, where the sediment accumulation rate was precisely determined. Sediment properties were determined using loss-on-ignition (LOI) and magnetic susceptibility (k). Dating methods used include both conventional and AMS 14C determinations, paleomagnetic dating and varve choronology. The isolation of Lake Kirjavalampi on the northern shore of Lake Ladoga took place ca. 1460 1300 BC. The long sediment cores from Finland, Lake Kirkkolampi and Lake Orijärvi in southeastern Finland and Lake Nautajärvi in south central Finland all extended back to the Early Holocene and were isolated from the Baltic basin ca. 9600 BC, 8600 BC and 7675 BC, respectively. In the long sediment cores, the expansion of Alnus was visible between 7200 - 6840 BC. The spread of Tilia was dated in Lake Kirkkolampi to 6600 BC, in Lake Orijärvi to 5000 BC and at Lake Nautajärvi to 4600 BC. Picea is present locally in Lake Kirkkolampi from 4340 BC, in Lake Orijärvi from 6520 BC and in Lake Nautajärvi from 3500 BC onwards. The first modifications in the pollen data, apparently connected to anthropogenic impacts, were dated to the beginning of the Early Metal Period, 1880 1600 BC. Anthropogenic activity became clear in all the study sites by the end of the Early Metal Period, between 500 BC AD 300. According to Secale pollen, slash-and-burn cultivation was practised around the eastern study lakes from AD 300 600 onwards, and at the study site in central Finland from AD 880 onwards. The overall human impact, however, remained low in the studied sites until the Late Iron Age. Increasing human activity, including an increase in fire frequency was detected from AD 800 900 onwards in the study sites in eastern Finland. In Lake Kirkkolampi, this included cultivation on permanent fields, but in Lake Orijärvi, permanent field cultivation became visible as late as AD 1220, even when the macrofossil data demonstrated the onset of cultivation on permanent fields as early as the 7th century AD. On the northern shore of Lake Ladoga, local activity became visible from ca. AD 1260 onwards and at Lake Nautajärvi, sediment the local occupation was traceable from 1420 AD onwards. The highest values of Secale pollen were recorded both in Lake Orijärvi and Lake Kirjavalampi between ca. AD 1700 1900, and could be associated with the most intensive period of slash-and-burn from AD 1750 to 1850 in eastern Finland.

Kohtaamisia Santiagon tiellä pyhiinvaellus matkana ja spirituaalisena kokemuksena

Pyhiinvaellustutkimuksen tavoitteena on kuvata, analysoida ja ymmärtää pyhiinvaeltajien kokemuksia ja erityisesti spirituaalisia tai sellaisiksi tulkittuja kokemuksia. Tutkimuskysymys voidaan muotoilla myös kysymällä, missä on vaeltajien mahdollisesti kokema pyhiinvaelluksen pyhä . Pyhiinvaellus suuntautuu Santiago de Compostelan kaupunkiin. Kuvattu pyhiinvaellusreitti alkaa Ranskan ja Espanjan rajalta ja kulkee Espanjan luoteiskulmassa noin 800 kilometrin päässä olevaan määränpäähän. Tutkimuksen aineistona on sähköpostikyselyn vastaukset, jotka on saatu kahdeltakymmeneltäkahdelta keväällä 2006 Santiagoon jalkaisin vaeltaneilta pyhiinvaeltajilta. Tutkimusaineistona ovat myös tutkijan omat havainnot ko. pyhiinvaellukselta. Tutkijan havainnoista on kirjoitettu kuvaus Santiagon tien pyhiinvaelluksesta ja matkan arkisista käytännöistä. Sähköpostikyselyn vastaukset, vaeltajien spirituaaliset kokemukset, on analysoitu laadullista sisällön analysointia käyttäen. Kuudesta vastauksesta on kirjoitettu myös pyhiinvaeltajan henkilökohtainen tarina. Narratiivisuus, kerronnallisuus, on tässä tutkimuksessa yksi tapa esittää, kuvata ja ymmärtää tutkimustuloksia. Tutkimus on liitetty fenomenologiseen viitekehykseen. Spirituaalisia kokemuksia on lähestytty mm. pyhiinvaellustradition, pyhän käsitteen ja uskonnollisten kokemusten näkökulmasta. Spiritualiteetin käsitettä ja spirituaalisen kokemuksen kuvaamisen mahdollisuuksia on myös pohdittu tutkimuksessa. Pyhiinvaelluksen spirituaaliset kokemukset on tutkimusraportissa jaoteltu seitsemään ryhmään: kävely, ihmiset, vapaus, luonto, rukous, kirkot ja Santiago. Lisäksi on esitetty matkaan lähdön motiiveja sekä pyhiinvaelluksen vaikutuksia elämässä. Käveleminen oli pyhiinvaelluksen ydinkokemus. Käveleminen mahdollisti meditaation tai rukoilemisen. Se aiheutti myös kärsimystä ja oli keskeinen ihmisiä yhdistävä teema. Pyhiinvaellus irrotti ihmiset erittäin hyvin arjen rutiineista ja jokapäiväisestä normaalista elämästä. Pyhiinvaelluksella vapauden tunne olikin merkittävä spirituaalinen kokemus ja ajan käsitys saattoi saa uuden ulottuvuuden. Luonto näyttäytyi merkittävänä spirituaalisen innoituksen lähteenä ja usein myös yksinolon paikkana. Kaikki pyhiinvaeltajat vierailivat kirkoissa ja katedraaleissa ja useimmat myös messuissa ja pyhiinvaeltajille järjestetyissä rukoushetkissä. Pyhiinvaelluksen uskonnollinen ulottuvuus oli kaikille läsnä myös Santiagon messussa. Kristillinen tulkintakehys kokemuksille oli koko ajan pyhiinvaeltajalle tarjolla. Kuitenkaan Santiagon vaellukseen ei välttämättä liittynyt mitään omaa spirituaalista kokemusta. Pyhiinvaelluksen merkittävät spirituaaliset kokemukset liittyivät yhteisöllisyyteen ja jaettuihin kokemuksiin. Tyypillinen moderni pyhiinvaeltaja etsi itseään pyhiinvaelluksella. Yllätyksekseen hän saattoi löytää jotain silloin kun hän antautui avoimeen vuorovaikutukseen toisten ihmisten kanssa. Lähes kaikki tutkimuksen osallistuneet pyhiinvaeltajat pitivät hyvin tärkeänä toisia pyhiinvaeltajia ja sitä, mitä he saivat toisilta ihmisiltä. Pyhiinvaellusta leimaa poikkeuksellisen avoin vuorovaikutus ja elämän jakaminen. Pyhiinvaellukseen liittyy monia individualistisia piirteitä. Spirituaalisten kokemusten näkökulmasta individualismi ei kuitenkaan saa tukea tutkimuksesta, koska yhteisöllisyys näyttää niin merkittävältä spirituaalisten kokemusten kannalta. Pyhiinvaelluksen yhteisöllisyys on avointa, vapaaehtoista ja usein myös hetkellistä. Moderni pyhiinvaeltaja näyttää uskovan enemmän omiin kokemuksiinsa ja myös toisten kokemuksiin kuin minkään kirkon opilliseen auktoriteettiin.

Vallankumous kotona! : Arkielämän visuaalinen murros 1960-luvun lopussa ja 1970-luvun alussa

Revolution at home! Visual Changes in Everyday Life in Finland in the Late 1960s and Early 1970s The purpose of my research was to investigate the visual changes in private homes in Finland during the 1960s and 1970s. The 1960s is often described as a turning point in Finnish life, a time when the society's previous agricultural orientation began to give way first to an industrial orientation and then, by the end of the 1970s, to a service orientation. My title refers to three elements in the transition period: the question of daily life; the timeframe; and the visual changes observable in private homes, which in retrospect signalled a kind of revolution in the social orientation. Those changes appeared not only in colours and designs but also in the forms and materials of household objects. My premise is that analysing interiors from a historical perspective can reveal valuable information about Finnish society and social attitudes, information that might easily escape attention otherwise. I have used the time-honoured method of collecting narratives. As far back as Aristotle, formulating narratives has been a means of gaining knowledge. By collecting and classifying narratives about the 1960s and 1970s, it is possible to gain new insight into these important decades. The archetypal 1960s narrative, involving student demonstrations and young people's efforts to improve society, is well known. Less well known is the narrative that relates the changes going on in daily life. Substantially the study focuses mainly on fabrics, porcelain ware and the use of plastics. Marimekko's style is especially important when following innovations in the 1950s, 1960s and 1970s. Porcelain production at the Arabia factory was another element that had a great influence on the look of Finnish homes and kitchens; and a further widespread phenomenon of the late 1960s and early 1970s was the use of plastics in many different forms. Further evidence was sought in Anttila department store mail catalogues, which displayed products that were marketed on a large scale, as well as in magazines such as Avotakka. The terminal point of the visual evolution is the real homes, as seen in the questionnaire "Homemade". I have used the 800 pages of the oral history text that respondents of the Finnish Literature Society have written about their first home in the 1960s. I also used archival material on actual homes in Helsinki from the archives of the Helsinki City Museum. The basic story is the elite narrative, which was produced by students in the 1960s. My main narrative from the same time is visual change in everyday life in the late 1960s and early 1970s. I have classified the main narrative of visual change into four subcategories: the narrative of national ideas, the narrative of a better standard of living, the narrative of objects in the culture of everyday life and the narrative of changing colour and form.

Polypore assemblages in boreal old-growth forests, and associated Coleoptera

This thesis examines assemblages of wood-decaying fungi in Finnish old-growth forests, and patterns of species interactions between fruit bodies of wood-rotting Basidiomycetes and associated Coleoptera. The present work is a summary of four original publications and a manuscript, which are based on empirical observations and deal with the prevalence of polypores in old-growth forests, and fungicolous Coleoptera. The study area consists of eleven old-growth, mostly spruce- and pine-dominated, protected forests rich in dead wood in northern and southeastern Finland. Supplementary data on fungus beetle interactions were collected in southern Finland and the Åland Islands. 11251 observations of fruit bodies from 153 polypore species were made in 789 forest compartments. Almost a half of the polypore species demonstrated a distinct northern or southeastern trend of prevalence. Polypores with a northern prevalence profile were in extreme cases totally absent from the Southeast, although almost uniformly present in the North. These were Onnia leporina, Climacocystis borealis, Antrodiella pallasii, Skeletocutis chrysella, Oligoporus parvus, Skeletocutis lilacina, and Junghuhnia collabens. Species with higher prevalence in the southeastern sites were Bjerkandera adusta, Inonotus radiatus, Trichaptum pargamenum, Antrodia macra, and Phellinus punctatus. 198 (86%) species of Finnish polypores were examined for associated Coleoptera. Adult beetles were collected from polypore basidiocarps in the wild, while their larvae were reared to adulthood in the lab. Spatial and temporal parallels between the properties of polypore fruit body and the species composition of Coleoptera in fungus beetle interactions were discussed. New data on the biology of individual species of fungivorous Coleoptera were collected. 116 species (50% of Finnish polypore mycota) were found to host adults and/or larvae of 179 species from 20 Coleoptera families. Many new fungus beetle interactions were found among the 614 species pairs; these included 491 polypore fruit body adult Coleoptera species co-occurrences, and 122 fruit body larva interrelations. 82 (41%) polypore species were neither visited nor colonized by Coleoptera. The total number of polyporicolous beetles in Finland is expected to reach 300 species.
