Erityisopetus muutoksen kynnyksellä - tilastollinen kuvaus erityisopetusjärjestelmästä ja sen määrällisestä kehityksestä 1970-luvun lopulta vuoteen 2008

The number of Finnish pupils attending special education has increased for more than a decade (Tilastokeskus 1999, 2000, 2001, 2003, 2004, 2005a, 2006b, 2007b, 2008b, 2008e, 2009b; Virtanen ja Ratilainen 1996). In the year 2007 nearly third of Finnish comprehensive school pupils took part in special needs education. According to the latest statistics, in the autumn of 2008 approximately 47 000 pupils have been admitted or transferred to special education and approximately 126 000 pupils received part-time special education during the 2007 - 2008 academic year. (Tilastokeskus 2008b, 2009b.) The Finnish special education system is currently under review. The Reform, both in legislation and in practice, began nationwide in the year 2008 (e.g. Special education strategy document, November 2007 and the development project Kelpo). The aim of the study was the statistical description of the Finnish special education system and on the other hand to gain a deeper understanding about the Finnish special education system and its quantitative increase, by analysis based on the nationwide statistical information. Earlier studies have shown that the growth in special education is affected by multiple independent variables and cannot be solely explained by the pupil characteristics. The statistical overview and analysis have been carried out in two parts. In the first part, the description and analysis were based on statistical time series from the academic year 1979 -1980 until 2008. While, in the second, more detailed description and analysis, based on comparable time series from 1995 to 2008 and from 2001-2002 to 2007-2008, is presented. Historical perspective was one part of this study. There was an attempt to find reasons explaining the observed growth in the special needs education from late 1960s to 2008. The majority of the research was based on the nationwide statistics information. In addition to this, materials including educational legislation literature, different kind of records of special education and preceding studies were also used to support the research. The main results of the study, are two statistical descriptions and time series analysis of the quantitative increase of the special needs education. Further, a summary of the plausible factors behind the special education system change and its quantitative increase, is presented. The conclusions coming from the study can be summarised as follows: the comparable statistical time series analysis suggests that the growth in special education after the year 1999 could be a consequence of the changes in the structure of special education and that new group of pupils have been directed to special needs education.

Tekstiilikulttuurisen lukutaidon edistäminen museoissa

Purpose: The study focuses on the question, how to advance textile cultural interpretation skills in museum. The theme was actual, because there have been many workshops in different kind of museums, which have raised textile into important role of their museum pedagogy. The knowing of nature of textile materials was highlighted in former studies as the most crucial thing in craft. That is reason for choosing textile to study. The theoretical approach of study was particularized to the meanings which have been given to craft during recent ten years. Furthermore the composition of textile culture and transmitting textile cultural heritage were examined throug the theory. The finnish museum as a place for learning, as well as the contens of museum pedagogy, were analyzed. The fundamental approach to study was cultural research and art education. Methods: The methodological approach was theory-based theme interview. Before interviewing informants the charting was made by using literature, interviews and observation, to find out the most important themes within subject. Specialists were interviewed personally and results were sent to them by e-mail for further comments. There were 8 informants and they were chosen with intentional sampling from different kind of museums, from teacher education and among craft teachers. Research material was analyzed with content analysis by using deductive reasoning. Conclusions: The study revealed that there are three strategies in advancing textile cultural interpretation. The most remarkable strategies are 1) making acquaintance of materials and working with them, 2) getting exiting events with posibilities to use one s whole body and 3) getting textile cultural knowledge by using for example discovery - style learning. In practice those strategies were mixed, which also was considered advisable. Another conclusion the study revealed, is the desirable, acceptable attitude not only to the craft with creative, free beginning but also to the craft made like its model in museum. Learning from model can be felt as a very moving experience, like a journey in time. The side result of the study was the importance of collaboration of museums and schools in advancing textile cultural interpretation skills as well as significance of using internet in collaboration and relations.

Lapsi ulkomailta – vanhempien rooli adoptiolapsen identiteetin kehityksessä

The importance of open discussion with the adopted child and his parents about adoption and ethnicity is often emphasized in adoption literature (Kirk 1964; Grotevant 1999; Carli & Dalen 1999). The child should have the possibility of constructing a harmonious view of himself, which consists of his history before adoption, ethnicity and the social environment’s conception of him. The purpose of this study was to examine the Finnish adoptive parents’ supportive role in relation to their child’s adoptive and ethnic identity and the social environment’s disposition to the child as witnessed by the parents. The first research problem was to find out how the parents support their child’s adoptive identity formation. The second problem was to find out if the parents want to support the child’s ethnic identity. The third problem was regarding the environment’s disposition to the child and family. The hypothesis was that Finnish adoptive parents are well aware of the problems of adoption and they have been well selected, so they have the aspirations and skills to help their child with his identity formation. The focus of this study was on Finnish parents who had adopted internationally, from whom 58 answers were obtained. The data was collected with an Internet based questionnaire. The questions were mostly qualitative. The analysis was directed by the theory, so that the analysis units were obtained from the main questions of international adoption and identity formation. The results expressed that the adoptive parents want to support their child’s adoption identity. They accept their child’s questions regarding his history, and that they did not want to conceal any details about their child’s life, even if they felt that it was a sensitive issue for them. The main problem was that there was no information available on the child’s history. Contact with the biological parents was almost impossible because there was hardly any information on them. Instead the parents were in contact with the children’s home because they felt that it had an important role as the child’s former home. The parents felt that the child’s birth culture was of importance and they mainly offered aspects of it informally daily. Parents who stressed their child’s Finnish identity were concerned that their child would not form a feeling of being Finnish. However, the majority wished that their child would have a multicultural identity. The parents felt that the environment regarded the child positively and the possibility of upcoming problems was tackled by discussing them beforehand with the child and environment.

Intergenerational Transfer of Sabbath Observance : How is Religious Tradition Transferred to Children among Finnish Seventh-day Adventists?

This study examined religious home education in educational, psychological, and sociological context. Growing up within a religious denomination is a process of learning the rules, norms, opinions, and attitudes, which serve to make the individual an active member of the group. It is a process of transferring the cultural inheritance between generations. Sabbathkeeping can be regarded as a strong indicator of the Seventh-day Adventist value system, which is also why I have concentrated on this specific issue in my study. The purpose of the study was to find out, how the Sabbath is transferred from parents to children among Finnish Adventists. It was also examined how parents could make the day of rest positively exceptional for children, and how the parental authoritativeness affects the process of transference. According to Bull & Lockhart s (1989) theory, the amount of Adventist generations in family history influences the transfer of religious tradition. This study aimed to find out whether or not this theory would apply to the present-day Finland. The nature of religious development among Adventist young people was also one of the interests of the research. The methods used in the study were in-depth interviews (n = 10) and a survey (n = 106). The majority of the interviewees was young adults (age 15-30) grown up in Adventist families. The interviews were taped and transcribed for the study, and survey answers were analysed with SPSS-data analysis program. The amount of survey questionnaires evaluated was 106, whole population of 15-30 year-old Finnish Adventists being about one thousand. Democratic relationship between parents and children, parents' example, encouragement to own thinking, and positive experiences of Sabbath and the whole religion, including the social dimension of the Adventism, seem to be some of the most significant factors in transference of religious tradition. Both too severe and too permissive education were considered to lead to similar results: unsuccessful transfer of values, or even rebellion and adopting a totally opposite way of life than that of the parents. In this study the amount of Adventist generations in family history does not correlate significantly with the end results of value transference.

Early-onset depressive disorders,related mental health disorders and substance use-A prospective : longitudinal study of Finnish twins born 1983-1987

Early-onset psychiatric illnesses effects scatter to academic achievements as well as functioning in familial and social environments. From a public health point of view, depressive disorders are the most significant mental health disorders that begin in adolescence. Using prospective and longitudinal design, this study aimed to increase the understanding of early-onset depressive disorders, related mental health disorders and developing substance use in a large population-derived sample of adolescent Finnish twins. The participants of this study, FinnTwin12, an ongoing longitudinal population-based study, came from Finnish families with twins born in 1983-87 (exhaustive of five birth cohorts, identified from Finland s Central Population Register). With follow-up ongoing at age 20-24, this thesis assessed adolescent mental health in the first three waves, starting from baseline age 11-12 to follow-ups at age 14 and 17½. Some 5600 twins participated in questionnaire assessments of a wide range of health related behaviors. Mental health was further assessed among an intensively studied subsample of 1852 adolescents, who completed also professionally administered interviews at age 14, which provided data for full DSM-IV/III-R (Diagnostic and Statistical Manual for Mental Health disorders, 4th and 3rd editions) diagnoses. The participation rates of the study were 87-92%. The results of the study suggest, that the diagnostic criteria for major depressive disorder (MDD) may not capture youth with clinically significant early-onset depressive conditions outside clinical settings. Milder cases of depression, namely adolescents fulfilling the diagnostic criteria for minor depressive disorder, a qualitatively similar condition to MDD with fewer symptoms are also associated with marked suicidal thoughts, plans and attempts, recurrences and a high degree of comorbidity. Prospectively and longitudinally, early-onset depressive disorders were of substantial importance in the context of other mental health disorders and substance use behaviors: These data from a large population-derived sample established a substantial overlap between early-onset depressive disorders and attention deficit hyperactivity disorder in adolescent females, both of them significantly predictive for development of substance use among girls. Only in females baseline DSM-IV ADHD symptoms were strong predictors of alcohol abuse and dependence and illicit drug use at age 14 and frequent alcohol use and illicit drug use at age 17.½ when conduct disorder and previous substance use were controlled for. Early-onset depressive disorders were also prospectively and longitudinally associated to daily smoking behavior, smokeless tobacco use, frequent alcohol use and illicit drug use and eating disorders. Analysis of discordant twins suggested that these predictive associations were independent of familial confounds, such as family income, structure and parental models. In sum, early-onset depressive disorders predict subsequent involvement of substance use and psychiatric morbidity. A heightened risk for substance use is substantial also among those depressed below categorical diagnosis of MDD. Whether early recognition and interventions among these young people hold potential for substance use prevention further in their lives has potential public health significance and calls for more research. Data from this population-derived sample with balanced representation of boys and girls, suggested that boys and girls with ADHD behaviors may differ from each other in their vulnerability to substance use and depressive disorders: the data suggest more adverse substance use outcome for girls that was not attenuated by conduct disorder or previous substance use. Further, the prospective associations of early-onset depressive disorders and future elevated levels of addictive substance use is not explained by familial factors supporting future substance use, which could have important implications for substance use prevention.

Pharmacogenetic Variation at CYP2D6, CYP2C9, and CYP2C19: Population Genetic and Forensic Aspects

Pharmacogenetics deals with genetically determined variation in drug response. In this context, three phase I drug-metabolizing enzymes, CYP2D6, CYP2C9, and CYP2C19, have a central role, affecting the metabolism of about 20-30% of clinically used drugs. Since genes coding for these enzymes in human populations exhibit high genetic polymorphism, they are of major pharmacogenetic importance. The aims of this study were to develop new genotyping methods for CYP2D6, CYP2C9, and CYP2C19 that would cover the most important genetic variants altering the enzyme activity, and, for the first time, to describe the distribution of genetic variation at these loci on global and microgeographic scales. In addition, pharmacogenetics was applied to a postmortem forensic setting to elucidate the role of genetic variation in drug intoxications, focusing mainly on cases related to tricyclic antidepressants, which are commonly involved in fatal drug poisonings in Finland. Genetic variability data were obtained by genotyping new population samples by the methods developed based on PCR and multiplex single-nucleotide primer extension reaction, as well as by collecting data from the literature. Data consisted of 138, 129, and 146 population samples for CYP2D6, CYP2C9, and CYP2C19, respectively. In addition, over 200 postmortem forensic cases were examined with respect to drug and metabolite concentrations and genotypic variation at CYP2D6 and CYP2C19. The distribution of genetic variation within and among human populations was analyzed by descriptive statistics and variance analysis and by correlating the genetic and geographic distances using Mantel tests and spatial autocorrelation. The correlation between phenotypic and genotypic variation in drug metabolism observed in postmortem cases was also analyzed statistically. The genotyping methods developed proved to be informative, technically feasible, and cost-effective. Detailed molecular analysis of CYP2D6 genetic variation in a global survey of human populations revealed that the pattern of variation was similar to those of neutral genomic markers. Most of the CYP2D6 diversity was observed within populations, and the spatial pattern of variation was best described as clinal. On the other hand, genetic variants of CYP2D6, CYP2C9, and CYP2C19 associated with altered enzymatic activity could reach extremely high frequencies in certain geographic regions. Pharmacogenetic variation may also be significantly affected by population-specific demographic histories, as seen within the Finnish population. When pharmacogenetics was applied to a postmortem forensic setting, a correlation between amitriptyline metabolic ratios and genetic variation at CYP2D6 and CYP2C19 was observed in the sample material, even in the presence of confounding factors typical for these cases. In addition, a case of doxepin-related fatal poisoning was shown to be associated with a genetic defect at CYP2D6. Each of the genes studied showed a distinct variation pattern in human populations and high frequencies of altered activity variants, which may reflect the neutral evolution and/or selective pressures caused by dietary or environmental exposure. The results are relevant also from the clinical point of view since the genetic variation at CYP2D6, CYP2C9, and CYP2C19 already has a range of clinical applications, e.g. in cancer treatment and oral anticoagulation therapy. This study revealed that pharmacogenetics may also contribute valuable information to the medicolegal investigation of sudden, unexpected deaths.

Male eating disorders and related traits : Genetic epidemiological study in Finnish twins

The aim of this study was to deepen the understanding of eating disorders, body image dissatisfaction and related traits in males by examining the epidemiology and genetic epidemiology of these conditions in representative population-based twin samples. The sample of Study I included adolescent twins from FinnTwin12 cohorts born 1983 87 and assessed by a questionnaire at ages 14 y (N=2070 boys, N=2062 girls) and 17 y (N=1857 boys, N=1984 girls). Samples of Studies II-V consisted of young adult twins born 1974-79 from FinnTwin16 cohorts (Study II N=1245 men, Study III N=724 men, Study IV N=2122 men, Study V N=2426 women and N=1962 men), who were assessed by a questionnaire at the age 22-28 y. In addition, 49 men and 526 women were assessed by a diagnostic interview. The overall response rates for both twin cohorts in all studies were 80-90%. In boys, mainly genetic factors (82%, 95% confidence interval [CI] 72-92) explained the covariation of self-esteem between the ages 14 y and 17 y, whereas in girls, environmental factors (69%, 95% CI 43-93) were the largest contributors. Of young men, 30% experienced high muscle dissatisfaction, while 12% used or had used muscle building supplements and/or anabolic steroids on a regular basis. Muscle dissatisfaction exhibited a robust association with the indicators of mental distress and a genetic component (42%, 95% CI 23-59) for its liability in this population was found. The variation of muscle-building substance use was primarily explained by the environmental factors. The incidence rate of anorexia nervosa in males for the age of 10-24 y was 15.7 (95% CI 6.6-37.8) per 100 000 person-years, and its lifetime prevalence by the young adulthood was 0.24% (95% CI 0.03-0.44). All detected probands with anorexia nervosa had recovered from eating disorders, but suffered from substantial psychiatric comorbidity, which manifested also in their co-twins. Additionally, male co-twins of the probands displayed significant dissatisfaction with body musculature, a male-specific feature of body dysmorphic disorder. All probands were from twin pairs discordant for eating disorders. Of the five male probands with anorexia nervosa, only one was from an opposite-sex twin pair. Among women from the opposite-sex pairs, the prevalence of DSM-IV or broad anorexia nervosa was no significantly different compared to that of the women from monozygotic pairs or from dizygotic same-sex pairs. The prevalence of DSM-IV or broad bulimia nervosa did not differ in opposite- versus same-sex female twin individuals either. In both sexes, the overall profile of indicators on eating disorders was rather similar between individuals from opposite-sex and same-sex pairs. In adolescence, development of self-esteem was differently regulated in boys compared to girls: this finding may have far-reaching implications on the etiology of sex discrepancy of internalizing and externalizing disorders. In young men, muscle dissatisfaction and muscle building supplement/steroid use were relatively common. Muscle dissatisfaction was associated with marked psychological distress such as symptoms of depression and disordered eating. Both genetic and environmental factors explained muscle dissatisfaction in the population, but environmental factors appeared to best explain the use of muscle-building substances. In this study, anorexia nervosa in boys and young men from the general population was more common, transient and accompanied by more substantial co-morbidity than previously thought. Co-twins of the probands with anorexia nervosa displayed significant psychopathology such as male specific symptoms of body dysmorphic disorder, but none of them had had an eating disorder: taken together, these traits are suggestive for an endophenotype of anorexia nervosa in males. Little evidence was found on that the risk for anorexia nervosa, bulimia nervosa, disordered eating or body dissatisfaction were associated with twin zygosity. Thus, it is unlikely that in utero femininization, masculinization or postnatal socialization according to the sex of the co-twin have a major influence on the later development of eating disorders or related traits.
