Cattle Teeth in Graves : Interpretations of animal bones found in Finnish inhumation graves (ca AD 550-1700)

The nature of a burial is always ritualistic. This is often forgotten when dealing with Finnish inhumation burials containing animal bones. Only the animal bones found close to the deceased have traditionally been thought to have a ritualistic purpose. The animal bones found in the filling of the grave, which is still part of the burial, has on the other hand, often been neglected in the previous research. In this Master s thesis I will discuss the function and interpretation of animal bones in graves. The base of this study is six sites, all of different nature, from Finland. Luistari in Eura is from the western coast and is dated to Late Iron Age (and possibly Medieval period), the Medieval hamlet of Finno is situated in Espoo which is situated on the southern coast. Two town burials, Turku and Porvoo, are also included in this study. The graves from Turku are dated to Late Medieval period and Early Renaissance, whereas the cemetery in Porvoo is from the 18th century. Visulahti in Mikkeli is from the Late Iron Age and represents Eastern Finnish burial tradition, the same as Suotniemi from Käkisalmi parish, which is nowadays part of Russia. While parts of the animal bones had already been analysed before, the author also analysed animal bones for the purpose of the present Master´s thesis. The bones were compared to the burial contexts, when possible. Based on the comparisons I have made interpretations which might explain the existence of animal bones in the graves. The interpretations are among others sacrifice, commemoration meals and animal burials. The site could also have been a settlement site prior to the graves, thus the bones in the graves would belong to the settlement phase. When comparing the date of the studied sites, the town burials are later and the animal bones are probably related to previous or contemporary use of the sites as graveyards. On top of this there does not seem to be much difference in burial tradition between Eastern and Western Finland, although at least from the hamlet burials of Finno there are aspects that could be linked to Eastern burials. In making the interpretations I have taken into consideration the aspects of belief during different time periods when they could be accounted as relevant. Also the problems with bone preservation were relevant and challenging for the study. Often only the hardest substance of the skeleton, namely teeth, has been preserved. For this reason the quality of the archaeological documentation was a key issue in this study. In producing quality interpretations of the animal bones in graves, the bones, contexts and their relationship to the surrounding site should be documented with care.

Do Households Have Rational Expectations on Future Consumption? Evidence from the Finnish Consumer Survey

Ever since its initial introduction some fifty years ago, the rational expectations paradigm has dominated the way economic theory handles uncertainty. The main assertion made by John F. Muth (1961), seen by many as the father of the paradigm, is that expectations of rational economic agents should essentially be equal to the predictions of relevant economic theory, since rational agents should use information available to them in an optimal way. This assumption often has important consequences on the results and interpretations of the models where it is applied. Although the rational expectations assumption can be applied to virtually any economic theory, the focus in this thesis is on macroeconomic theories of consumption, especially the Rational Expectations–Permanent Income Hypothesis proposed by Robert E. Hall in 1978. The much-debated theory suggests that, assuming that agents have rational expectations on their future income, consumption decisions should follow a random walk, and the best forecast of future consumption level is the current consumption level. Then, changes in consumption are unforecastable. This thesis constructs an empirical test for the Rational Expectations–Permanent Income Hypothesis using Finnish Consumer Survey data as well as various Finnish macroeconomic data. The data sample covers the years 1995–2010. Consumer survey data may be interpreted to directly represent household expectations, which makes it an interesting tool for this particular test. The variable to be predicted is the growth of total household consumption expenditure. The main empirical result is that the Consumer Confidence Index (CCI), a balance figure computed from the most important consumer survey responses, does have statistically significant predictive power over the change in total consumption expenditure. The history of consumption expenditure growth itself, however, fails to predict its own future values. This indicates that the CCI contains some information that the history of consumption decisions does not, and that the consumption decisions are not optimal in the theoretical context. However, when conditioned on various macroeconomic variables, the CCI loses its predictive ability. This finding suggests that the index is merely a (partial) summary of macroeconomic information, and does not contain any significant private information on consumption intentions of households not directly deductible from the objective economic variables. In conclusion, the Rational Expectations–Permanent Income Hypothesis is strongly rejected by the empirical results in this thesis. This result is in accordance with most earlier studies conducted on the topic.

Iäkkäiden lääkehoitoihin liittyvien riskien kartoittaminen – Arviointityökalun kehittäminen Delfoi-menetelmällä

Tutkimuksen taustalla on väestön ikääntyminen ja iäkkäiden lisääntynyt lääkkeiden käyttö. Ikääntyminen aiheuttaa elimistössä useita muutoksia, jotka voivat muuttaa lääkevastetta ja altistaa potilaan haittavaikutuksille. Iäkkäillä riski joutua sairaalaan lääkkeen haittavaikutuksen vuoksi on arvioitu olevan neljä kertaa suurempi kuin nuoremmilla. Monet lääkkeiden yhteis- ja haittavaikutukset olisivat ehkäistävissä välttämällä iäkkäillä tiettyjä lääkeaineita. Iäkkäiden lääkehoitojen seurantaa ja arviointia varten on kehitetty erilaisia suosituksia sekä Suomessa että kansainvälisesti. Tutkimuksen tavoitteena oli luoda Suomen oloihin soveltuva, hoitajien koulutettuina käytettävissä oleva, avohoidon yli 65-vuotiaiden iäkkäiden lääkitykseen liittyviä riskejä arvioiva työkalu. Työkalun avulla voitaisiin löytää ne potilaat, joiden lääkitykseen liittyy paljon riskejä. Tutkimuksen aineistona olivat laaja kansainvälinen kirjallisuuskatsaus iäkkäiden lääkehoitoihin liittyvistä tekijöistä sekä asiantuntijakommentoinnit, joiden perusteella luotiin alustava arviointityökalu. Alustava arviointityökalu validoitiin kolmikierroksisella Delfoi-menetelmällä. Delfoi-menetelmä on laadullinen konsensusmenetelmä, joka perustuu asiantuntijoiden arvioihin tutkittavasta asiasta. Kaksi ensimmäistä Delfoi-kierrosta mittasivat alustavan arviointityökalun kohtien soveltuvuutta ja kolmas kierros kohtien tärkeyttä arvioitaessa iäkkään lääkityksiin liittyviä riskejä. Tutkimuksen Delfoi-kierroksien vastaajiksi pyydettiin 33 geriatrian asiantuntijaa, joista vastaajiksi lupautui 11 lääkäriä, 3 proviisoria ja 4 sairaanhoitajaa. Delfoi-kierrosten tuloksia analysoitiin sekä kvantitatiivisesti että kvalitatiivisesti. Tutkimuksen tuloksena saatu arviointityökalu käsittää 19 iäkkäiden lääkehoitoa arvioivaa kohtaa. Asiantuntijapaneelin mukaan kaikki arviointityökalun lääkitykseen liittyviä riskejä mittaavat kohdat ovat tärkeitä tai jokseenkin tärkeitä, joten työkalun voidaan olettaa olevan validi mitattaessa lääkitykseen liittyviä riskejä. Jatkotutkimuksissa työkalun käytettävyyttä sekä riskien mittaamiskykyä tulee testata sekä arviointityökalun käyttäjien että potilaiden keskuudessa. Kehitettyä työkalua voidaan jatkossa hyödyntää esimerkiksi koulutustarkoituksissa sen varsinaisen käyttötarkoituksen lisäksi. Työkalun avulla iäkkäiden lääkehoitoa voidaan tulevaisuudessa toteuttaa entistä turvallisemmin ja tarkoituksenmukaisemmin.

Campylobacter jejuni and C. coli in Finnish poultry production

Campylobacter, mainly Campylobacter jejuni and C. coli, are worldwide recognized as a major cause of bacterial food-borne gastroenteritis. Epidemiological studies have shown handling or eating of poultry to be significant risk factors for human infections. Campylobacter contamination can occur at all stages of a poultry meat production cycle. The aim of this thesis was to study the occurrence and diversity of Campylobacter in broiler and turkey production in Finland. In summer 1999, 2.9 % of slaughtered broiler flocks were Campylobacter-positive. From the isolated strains 94 % were C. jejuni and 6% were C. coli. During years 2005-2006 one turkey parent flock, the hatchery, six different commercial turkey farms and different stages of the slaughterhouse were monitored during one and the half year. No Campylobacter were detected in either of the samples from the turkey parent flock or from the hatchery using the culture method. Instead PCR detected DNA of Campylobacter from the turkey parent flock and samples from the hatchery. Six out of 12 commercial turkey flocks were found negative at the farm level but only two of those were negative at slaughter. Campylobacter-positive samples within the flock at slaughter were detected between 0% and 94% with evisceration and chilling water being the most critical stages for contamination. All of Campylobacter isolates were shown to be C. jejuni. Campylobacter-positive turkey flocks were colonized by a limited number of Campylobacter genotypes both at the farm and slaughter level. In conclusion, in our first study in 1999 a low prevalence of Campylobacter in Finnish broiler flocks was detected and it has remained at a low level during the study period until the present. In the turkey meat production, we found that flocks which were negative at the farm became contaminated with Campylobacter at the slaughter process. These results suggest that proper and efficient cleaning and disinfection of slaughter and processing premises are needed to avoid cross-contamination. Prevention of colonization at the farm by a high level of biosecurity control and hygiene may be one of the most efficient ways to reduce the amount of Campylobacter-positive poultry meat in Finland. With a persistent low level of Campylobacter-positive flocks, it could be speculated that the use of logistic slaughtering, according to Campylobacter status at farm, might have be advantageous in reducing Campylobacter contamination of retail poultry products. However, the significance of the domestic poultry meat for human campylobacteriosis in Finland should be evaluated.

Factors affecting partitioning of private forest holdings in Finland.

Questions of the small size of non-industrial private forest (NIPF) holdings in Finland are considered and factors affecting their partitioning are analyzed. This work arises out of Finnish forest policy statements in which the small average size of holdings has been seen to have a negative influence on the economics of forestry. A survey of the literature indicates that the size of holdings is an important factor determining the costs of logging and silvicultural operations, while its influence on the timber supply is slight. The empirical data are based on a sample of 314 holdings collected by interviewing forest owners in the years 1980-86. In 1990-91 the same holdings were resurveyed by means of a postal inquiry and partly by interviewing forest owners. The principal objective in compiling the data is to assist in quantifying ownership factors that influence partitioning among different kinds of NIPF holdings. Thus the mechanism of partitioning were described and a maximum likelihood logistic regression model was constructed using seven independent holding and ownership variables. One out of four holdings had undergone partitioning in conjunction with a change in ownership, one fifth among family owned holdings and nearly a half among jointly owned holdings. The results of the logistic regression model indicate, for instance, that the odds on partitioning is about three times greater for jointly owned holdings than for family owned ones. Also, the probabilities of partitioning were estimated and the impact of independent dichotomous variables on the probability of partitioning ranged between 0.02 and 0.10. The low value of the Hosmer-Lemeshow test statistic indicates a good fit of the model and the rate of correct classification was estimated to be 88 per cent with a cutoff point of 0.5. The average size of holdings undergoing ownership changes decreased from 29.9 ha to 28.7 ha over the approximate interval 1983-90. In addition, the transition probability matrix showed that the trends towards smaller size categories mostly involved in the small size categories, less than 20 ha. The results of the study can be used in considering the effects of the small size of holdings for forestry and if the purpose is to influence partitioning through forest or rural policy.

Quest for authenticity - representation of the Sami image in Christmas tourism

Tourism is one of important livelihoods in Lapland. Christmas tourism was launched in the early 1980s and it became a success story - being labelled as the most epochal tourism product in Finland. Hence, today Christmas tourists are one of the most significant foreign groups arriving to Lapland during the winter season and contributing considerably to the economics of the northeastern periphery of the EU. Christmas tourism concentrates around Father Christmas who uses reindeer for transportation. The Sämi are the only indigenous people in the EU. They are all stereotypically perceived to be reindeer herders. Somehow these three, that is, Santa Claus, reindeer and the Sämi, have been incorporated into same fairytale dominion. In practice, this has happened by using the most visible cultural but also significant identity marker of the Sämi, the Sämi costume. This, in turn, has created controversy over authenticity due to manners in which the costume is used in tourism - often in imitational, mismatched forms by non-Sämi. In this thesis, after relevant literature review I intend to establish how the Sâmi are represented in Christmas tourism through visual data consisting of ten images from three foreign sources. Then I clarify why and to whom it matters of how the Sâmi are represented in Christmas tourism with the aid of 65 questionnaires and nineteen expert interviews collected mainly in the Finnish Sâmi Home Region in October 2009. Through the multiplicity of the voices of various interest and ethnic groups and by using critical discourse analysis I attempt to give an overview of the respondents' opinions and look at some preliminary solutions to the controversy. Based on my data, the non-Sami appear to accept the Sami costume usage in Christmas tourism most readily. Consequently, respect and attitudinal changes have become the respondents' propositions in addition to common set of rules of how the Sami image could be appropriated without violating the integrity of the Sami people, or a similar system of S¿m¡ Duodji trademark guaranteeing the authenticity of the tourism products. Additionally, though half of the interviewees explicate Sami presence in Christmas tourism by adding local flavour to otherwise commercial enterprise, the other half see no rationale to connect facts with fiction, that is, the Sami with Santa Claus.

Factor V Leiden as risk factor for pregnancy complications : Epidemiological study of Finnish women

Factor V Leiden (FV Leiden) is the most common inherited thrombophilia in Caucasians increasing the risk for venous thrombosis. Its prevalence in Finland is 2-3%. FV Leiden has also been associated with several pregnancy complications. However, the importance of FV Leiden as their risk factor is unclear. The aim of the study was to assess FV Leiden as a risk factor for pregnancy complications in which prothrombotic mechanisms may play a part. Specifically, the study aimed to assess the magnitude of the risk, if any, associated with FV Leiden for pregnancy-associated venous thrombosis, pre-eclampsia, unexplained stillbirth, and preterm birth. The study was conducted as a nested case-control study within a fixed cohort of 100,000 consecutive pregnant women in Finland. The study was approved by the ethics committee of the Finnish Red Cross Blood Service and by the Ministry of Social Affairs and Health. All participants gave written informed consent. Cases and controls were identified by using national registers. The diagnoses of the 100,000 women identified from the National Register of Blood Group and Blood Group Antibodies of Pregnant Women were obtained from the National Hospital Discharge Register. Participants gave blood samples for DNA tests and filled in questionnaires. The medical records of the participants were reviewed in 49 maternity hospitals in Finland. Genotyping was performed in the Finnish Genome Center. When evaluating pregnancy-associated venous thrombosis (34 cases, 641 controls), FV Leiden was associated with 11-fold risk (OR 11.6, 95% CI 3.6-33.6). When only analyzing women with first venous thrombosis, the risk was 6-fold (OR 5.8, 95% CI 1.6-21.8). The risk was increased by common risk factors, the risk being highest in women with FV Leiden and pre-pregnancy BMI over 30 kg/m2 (75-fold), and in women with FV Leiden and age over 35 years (60-fold). When evaluating pre-eclampsia (248 cases, 679 controls), FV Leiden was associated with a trend of increased risk (OR 1.7, 95% CI 0.8-3.9), but the association was not statistically significant. When evaluating unexplained stillbirth (44 cases, 776 controls), FV Leiden was associated with over 3-fold risk (OR 3.8, 95% CI 1.2-11.6). When evaluating preterm birth (324 cases, 752 controls), FV Leiden was associated with over 2-fold risk (OR 2.4, 95% CI 1.3-4.6). FV Leiden was especially associated with late preterm birth (32-36 weeks of gestation), but not with early preterm birth (< 32 weeks of gestation). The results of this large population-based study can be generalized to Finnish women with pregnancies continuing beyond first trimester, and may be applied to Caucasian women in populations with similar prevalence of FV Leiden and high standard prenatal care.

Valistus suomalaisessa kirjakulttuurissa 1700-luvulla

The dissertation discusses the history of the book and the Enlightenment in Finland by studying the reception and diffusion of eighteenth-century books and by approaching the discourse on the Enlightenment in Finnish source material. The methods used relate to historian Robert Darnton s studies on eighteenth-century print culture and his analyses of the relations between print culture and society. The study is based on diverse eighteenth-century sources: books, pamphlets and dissertations, bibliographies, book auction protocols, parliamentary documents, estate inventory deeds, newspapers, letters, lectures, memoirs and commonplace books. By the end of the eighteenth century, book production had increased and secular literature had begun to challenge the dominance of religious literature. The books of the Enlightenment belonged to the new literature that found its way into Finnish book collections previously dominated by religious literature. Enlightenment literature is not a set selection of books but rather diverse works from different genres. Thus the study introduces a variety of printed material, from philosophical tracts and textbooks to novels and pornography. In the case of books of the Enlightenment, the works of French Voltaire and German Christian Wolff were among the most widely read and circulated books in Finland. First and foremost, the Enlightenment was an era of intellectual debate. These debates carried strong criticism of the prevailing systems of thought. Enlightenment ideas challenged the Lutheran society of Sweden and especially its sense of conformity. Contemporaries saw many of the books of the Enlightenment as vessels of new ideas and criticism. Furthermore, this kind of print material was interpreted as being dangerous for uneducated readers. Belonging to a certain estate and social class had a major impact on individuals reading habits and their acquisition of books. One specific social group stands out in the Finnish source material: the officers at the Sveaborg naval fortress possessed and distributed Enlightenment books more than the members of any other social class. Other essential social groups were scholars, the nobility and the clergy, who took part in debates concerning the ideas and benefits of the Enlightenment. In the Finnish debates at the time, the concept of Enlightenment involved three primary notions. Firstly, it referred to the French philosophers, les philosophes, and to their works as well as to the social changes that took place during the French revolution. It also carried the idea of philosophical light or the light of reason, in a sense similar to Immanuel Kant s writings. Most importantly, it referred to a belief in progress and to a trust in true knowledge that would supercede ignorance and fanaticism. Hence, it is impossible to speak about the Enlightenment era in the Swedish realm without such concepts as reason, benefit or progress. These concepts likewise marked the books of the Enlightenment in eighteenth-century Finland.

Campylobacter jejuni and C.coli in Finnish poultry production

Campylobacter, mainly Campylobacter jejuni and C. coli, are worldwide recognized as a major cause of bacterial food-borne gastroenteritis (World Health Organization 2010). Epidemiological studies have shown handling or eating of poultry to be significant risk factors for human infections. Campylobacter contamination can occur at all stages of a poultry meat production cycle. In summer 1999, every broiler flock from all three major Finnish poultry slaughterhouses was studied during a five month period. Caecal samples were taken in the slaughterhouses from five birds per flock. A total of 1 132 broiler flocks were tested and 33 (2.9%) of those were Campylobacter-positive. Thirty-one isolates were identified as C. jejuni and two isolates were C. coli. The isolates were serotyped for heat-stable antigens (HS) and genotyped by pulsed-field gel electrophoresis (PFGE). The most common serotypes found were HS 6,7, 12 and 4-complex. Using a combination of SmaI and KpnI patterns, 18 different PFGE types were identified. Thirty-five Finnish C. jejuni strains with five SmaI/SacII PFGE types selected among human and chicken isolates from 1997 and 1998 were used for comparison of their PFGE patterns, amplified fragment length polymorphism (AFLP) patterns, HaeIII ribotypes, and HS serotypes. The discriminatory power of PFGE, AFLP and ribotyping with HaeIII were shown to be at the same level for this selected set of strains, and these methods assigned the strains into the same groups. The PFGE and AFLP patterns within a genotype were highly similar, indicating genetic relatedness. An HS serotype was distributed among different genotypes, and different serotypes were identified within one genotype. From one turkey parent flock, the hatchery, six different commercial turkey farms (together 12 flocks) and from 11 stages at the slaughterhouse a total of 456 samples were collected during one and the half year. For the detection of Campylobacter both conventional culture and a PCR method were used. No Campylobacter were detected in either of the samples from the turkey parent flock or from the hatchery samples using the culture method. Instead PCR detected DNA of Campylobacter in five faecal samples from the turkey parent flock and in one fluff and an eggshell sample. Six out of 12 commercial turkey flocks were found negative at the farm level but only two of those were negative at slaughter. Campylobacter-positive samples within the flock at slaughter were detected between 0% and 94%, with evisceration and chilling water being the most critical stages for contamination. All of a total of 121 Campylobacter isolates were shown to be C. jejuni using a multiplex PCR assay. PFGE analysis of all isolates with KpnI restriction enzyme resulted in 11 PFGE types (I-XI) and flaA-SVR typing yielded nine flaA-SVR alleles. Three Campylobacter-positive turkey flocks were colonized by a limited number of Campylobacter genotypes both at the farm and slaughter level.In conclusion, in our first study in 1999 a low prevalence of Campylobacter in Finnish broiler flocks was detected and it has remained at a low level during the study period until the present. In the turkey meat production, we found that flocks which were negative at the farm became contaminated with Campylobacter at the slaughter process. These results suggest that proper and efficient cleaning and disinfection of slaughter and processing premises are needed to avoid cross-contamination. Prevention of colonization at the farm by a high level of biosecurity control and hygiene may be one of the most efficient ways to reduce the amount of Campylobacter-positive poultry meat in Finland. In Finland, with a persistent low level of Campylobacter-positive flocks, it could be speculated that the use of logistic slaughtering, according to Campylobacter status at farm, might have be advantageous in reducing Campylobacter contamination of retail poultry products. However, the significance of the domestic poultry meat for human campylobacteriosis in Finland should be evaluated.

A Shared European History? Perceptions of Imperialism and Islam in Matriculation Examination Essays and History Textbooks

The European Union (EU) is faced with a continuous decrease in public support. There is a tension between the growing Euroscepticism and the concurrent academic discourse of a shared European identity. Informed and inspired by the current debates, this Master’s Thesis investigates the potential of a shared past to create shared identity. It also addresses the logic of cultural exclusion that is often connected to collective cultural identities. The source material is a combination of exam essays, written as answers to the history tests in the Finnish matriculation examinations of 2005-2008, and upper secondary school history textbooks. From the sources, current perceptions of Islam (as Europe’s Other) and the age of imperialism (as a debated period from Europe’s past) among the youth are studied. Through the analysis the thesis aims to indicate the level of consensus within the pupils’ identification with the past and with Europe. This objective is pursued through examining the pupils’ perceptions of Europe’s past and its relationship to non-European cultures and countries as they are manifested in the essays, and reflecting upon the level of influence that history textbooks as representatives of national hegemonic historical narratives might have on the contents, framings and emphases with and through which the pupils approach, imagine, and reproduce Europe’s past. The approach is based on previous research on the presence of history and the field of textbook research. The theoretical categories with which the sources are analyzed are derived primarily from literature on identity, European integration, history and memory, postcolonial criticism, and theorizations of European identity. Results of the research project suggest that the rhetoric of European superiority, despite its apparent demise, still resonates in contemporary understandings of Europeanness. Dominant perceptions of imperialism comprise of European agency and colonial submission, dominant perceptions of the Islamic world of fundamental difference. Identification with European history among the Finnish youth is rather shallow when examined through perceptions of imperialism; the Islamic world is perceived as Other and its representations are dominated by recent and contemporary international relations.
