The aim of this study was to investigate the connection between teachers' burn-out and professional development. In addition, the study aimed at clarifying teachers' conceptions of the significance of in-service training on work-related well-being. The theoretical starting points of the study were based on a model of burn-out (Kalimo & Toppinen1997) and a model of teachers' professional development (Niemi 1989). Present study can be seen as an independent follow-up study for a working ability project called "Uudistumisen eväät" that was followed through in Kuopio. The study was carried out in two phases. First, the connection between teachers' burn-out and professional development was charted with the help of a quantitative survey study. 131 teachers participated in the survey. Some of them were from schools that participated in the working ability project and the remainder were from other schools in Kuopio. The questionnaire consisted of self-constructed instruments of burn-out and professional development. According to the results, burn-out and professional development were strongly correlated with each other. Burn-out was summed up in three factors: emotional exhaustion, feelings of depersonalization and low feelings of personal accomplishment. Professional development was summed up in four factors: personality and pedagogical skills, learning-orientation, social skills and confronting change. Personality and pedagogical skills and skills of confronting change were correlated strongest with burn-out and its symptoms. A teacher, who has not found his/her own personal way of acting as a teacher and who considers change as something negative, is more likely to become exhausted than a teacher, who has developed his/her own pedagogical identity and who regards change more positively. In the second phase of this study, teachers' conceptions of the significance of in-service training on well-being was investigated with the help of group interviews (n=12). According to the results, the importance of in-service training was significant on the well-being of teachers. It appeared that in-service training promotes well-being by providing teachers with motivation, professional development and the possibility of taking a break from teaching and cooperating with other teachers. It has to be based on teachers' own needs. It has to be offered to teachers frequently and early enough. If teachers are already exhausted, they will neither have enough resources to participate in training, nor will they have the strength to make good use of it in practice. Both professional development and well-being are becoming more and more essential now that society is changing rapidly and the demands set on teachers are growing. Professional development can promote well-being, but are teachers too exhausted to develop themselves? Professional development demands resources and teachers may regard it as a threat and an additional strain. When the demands are so high that teachers cannot cope with them, they are likely to suffer stress and see reduction of commitment to their work and its development as a means to survive. If teachers stop caring about their work and their own development, how can we expect them to promote pupils' learning and development? It should be considered in the planning and implementation of in-service training and in arranging teachers' working conditions, that teachers have enough time and resources to develop themselves.

Quantitative trait loci detection and benefits from marker-assisted selection in dairy cattle

Knowing the chromosomal areas or actual genes affecting the traits under selection would add more information to be used in the selection decisions which would potentially lead to higher genetic response. The first objective of this study was to map quantitative trait loci (QTL) affecting economically important traits in the Finnish Ayrshire population. The second objective was to investigate the effects of using QTL information in marker-assisted selection (MAS) on the genetic response and the linkage disequilibrium between the different parts of the genome. Whole genome scans were carried out on a grand-daughter design with 12 half-sib families and a total of 493 sons. Twelve different traits were studied: milk yield, protein yield, protein content, fat yield, fat content, somatic cell score (SCS), mastitis treatments, other veterinary treatments, days open, fertility treatments, non-return rate, and calf mortality. The average spacing of the typed markers was 20 cM with 2 to 14 markers per chromosome. Associations between markers and traits were analyzed with multiple marker regression. Significance was determined by permutation and genome-wise P-values obtained by Bonferroni correction. The benefits from MAS were investigated by simulation: a conventional progeny testing scheme was compared to a scheme where QTL information was used within families to select among full-sibs in the male path. Two QTL on different chromosomes were modelled. The effects of different starting frequencies of the favourable alleles and different size of the QTL effects were evaluated. A large number of QTL, 48 in total, were detected at 5% or higher chromosome-wise significance. QTL for milk production were found on 8 chromosomes, for SCS on 6, for mastitis treatments on 1, for other veterinary treatments on 5, for days open on 7, for fertility treatments on 7, for calf mortality on 6, and for non-return rate on 2 chromosomes. In the simulation study the total genetic response was faster with MAS than with conventional selection and the advantage of MAS persisted over the studied generations. The rate of response and the difference between the selection schemes reflected clearly the changes in allele frequencies of the favourable QTL. The disequilibrium between the polygenes and QTL was always negative and it was larger with larger QTL size. The disequilibrium between the two QTL was larger with QTL of large effect and it was somewhat larger with MAS for scenarios with starting frequencies below 0.5 for QTL of moderate size and below 0.3 for large QTL. In conclusion, several QTL affecting economically important traits of dairy cattle were detected. Further studies are needed to verify these QTL, check their presence in the present breeding population, look for pleiotropy and fine map the most interesting QTL regions. The results of the simulation studies show that using MAS together with embryo transfer to pre-select young bulls within families is a useful approach to increase the genetic merit of the AI-bulls compared to conventional selection.

Kuluttajuuden rakentuminen nuorten kertomuksissa

This study examines the narrative construction of consumerism in Finnish consumer culture in the early 21st century. The objects of the study are consumer life stories and essays on environmentally friendly consumption, written by 15-19-year-old high school students. Moreover, group discussions were used as additional research material. The data was gathered at five high schools in different areas of Finland. Young people's consumer narratives are interpreted through cultural stories and consumer ethos such as self-control, gratification and green consumerism. The narrative research approach is used to analyse what types of consumer positions these young people construct in stories on their own consumer history, and what kinds of ideas and thought patterns they construct on green consumerism. The study creates a multifaceted image of young people as agents in consumer society. They construct archetypical stories of wastrels and scrooges, as well as prudent and environmentally friendly consumers. Consumption and expenditure are however mostly a continuous battle between self-control and giving in to gratification. This reality is illustrated among other things by clever expressions invented by young people, such as Carefree Pennywise, Prudent Hedonist and Wasteful Scrooge. In their narratives, young people also analyse the usefulness - or uselessness - of their decisions on consumption, as well as develop themselves into controlling and sensible consumers. This kind of virtuous consumer allows him/herself the joy and the gratification of consumption, as long as these are "kept in check". One's view of expenditure and consumption is not permanent. Consumerism may alter with time. A wastrel may grow up to be a young person in control of their desires, or a thrifty child may awaken to the pleasures of consumption in their teens. Consumerism may also be polyphonic: it may simultaneously - and even uncomplicatedly - be constructed upon the discourses of wastefulness, prudence, gratification and green consumerism. Young people allow for gratification to form a part of green consumerism, too: it is not simply restrictive self-denial. They also see many hurdles in the way of green consumerism, such as the elevated price of ecological products, and the difficulties of green consumer practices. The stories also show the gender division in green consumerism. For young men, ecological considerations offer elements for the construction of consumerism only on the very rare occasion, whereas striving for day-to-day green practices is typical for young women.

The influence of school smoking policy and school prevention programs on the smoking behaviour of high school students in Prince Edward Island, Canada

The aim of the study was to examine the influence of school smoking policy and school smoking prevention programs on the smoking behaviour of students in high schools in Prince Edward Island using the School Health Action Planning Evaluation System (SHAPES). A total sample included 13,131 observations of students in grades 10-12 in ten high schools in Prince Edward Island over three waves of data collection (1999, 2000, and 2001). Changes in prevalence of smoking and factors influencing smoking behaviour were analyzed using descriptive statistics and Chi-Square tests. Multi-level logistic regression analyses were used to examine how both school and student characteristics were associated with smoking behaviour (I, II, III, IV). Since students were located within schools, a basic 2-level nested structure was used in which individual students (level 1) were nested within schools (level 2). For grade 12 students, the combination of both school policies and programs was not associated with the risk of smoking and the presence of the new policy was not associated with decreased risk of smoking, unless there were clear rules in place (I). For the grade 10 study, (II) schools with both policies and programs were not associated with decreased risk of smoking. However, the smoking behaviour of older students (grade 12) at a school was associated with younger students’ (grade 10) smoking behaviour. Students first enrolled in a high school in grade 9, rather than grade 10, were at increased risk of occasional smoking. For students who transitioned from grade 10 to 12 (III), close friends smoking had a substantial influence on smoking behaviour for both males and females (III). Having one or more close friends who smoke (Odds Ratio (OR) = 37.46; 95% CI = 19.39 to 72.36), one or more smokers in the home (OR = 2.35; 95% CI = 1.67 to 3.30) and seeing teachers and staff smoking on or near school property (OR=1.78; 95% CI = 1.13 to 2.80), were strongly associated with increased risk of smoking for grade 12 students. Smoking behaviour increased for both junior (Group 1) and senior (Group 2) students (IV). Group 1 students indicated a greater decrease in smoking behaviour and factors influencing smoking behaviour compared to those of Group 2. Students overestimating the percentage of youth their age who smoke was strongly associated with increased likelihood of smoking. Smoking rates showed a decreasing trend (1999, 2000, and 2001). However, policies and programs alone were not successful in influencing smoking behaviour of youth. Rather, factors within the students and schools contextual environment influenced smoking behaviour. Comprehensive approaches are required for school-based tobacco prevention interventions.

Combined Tevatron upper limit on gg->H->W+W- and constraints on the Higgs boson mass in fourth-generation fermion models

We combine results from searches by the CDF and D0 collaborations for a standard model Higgs boson (H) in the process gg->H->W+W- in p=pbar collisions at the Fermilab Tevatron Collider at sqrt{s}=1.96 TeV. With 4.8 fb-1 of integrated luminosity analyzed at CDF and 5.4 fb-1 at D0, the 95% Confidence Level upper limit on \sigma(gg->H) x B(H->W+W-) is 1.75 pb at m_H=120 GeV, 0.38 pb at m_H=165 GeV, and 0.83 pb at m_H=200 GeV. Assuming the presence of a fourth sequential generation of fermions with large masses, we exclude at the 95% Confidence Level a standard-model-like Higgs boson with a mass between 131 and 204 GeV.

Every method counts

In this study we explore the concurrent, combined use of three research methods, statistical corpus analysis and two psycholinguistic experiments (a forced-choice and an acceptability rating task), using verbal synonymy in Finnish as a case in point. In addition to supporting conclusions from earlier studies concerning the relationships between corpus-based and ex- perimental data (e. g., Featherston 2005), we show that each method adds to our understanding of the studied phenomenon, in a way which could not be achieved through any single method by itself. Most importantly, whereas relative rareness in a corpus is associated with dispreference in selection, such infrequency does not categorically always entail substantially lower acceptability. Furthermore, we show that forced-choice and acceptability rating tasks pertain to distinct linguistic processes, with category-wise in- commensurable scales of measurement, and should therefore be merged with caution, if at all.

Finnish cattle as reservoir of Campylobacter spp.

The reported incidence of human campylobacteriosis in Finland is higher than in most other European countries. A high annual percentage of sporadic infections is of foreign origin, although a notable proportion of summer infections is domestically acquired. While chickens appear to be a major source of campylobacters for humans in most countries, the prevalence of campylobacters is very low in chicken slaughter batches in Finland. Data on other potential animal reservoirs of human pathogenic campylobacters in Finland are scarce. Consequently, this study aimed to investigate the status of Finnish cattle as a potential source of thermophilic Campylobacter spp. and antibiotic-resistant Campylobacter jejuni for human sporadic campylobacter infections of domestic origin. A survey of the prevalence of thermophilic Campylobacter spp. in Finnish cattle studied bovine rectal faecal samples (n=952) and carcass surface samples (n=948) from twelve Finnish slaughterhouses from January to December 2003. The total prevalence of Campylobacter spp. in faecal samples was 31.1%, and in carcass samples 3.5%. Campylobacter jejuni, the most common species, was present in 19.5% of faecal samples and in 3.1% of carcasses. In addition to thermophilic Campylobacter spp., C. hyointestinalis ssp. hyointestinalis was present in bovine samples. The prevalence of campylobacters was higher among beef cattle than among dairy cattle. Using the enrichment method, the number of positive faecal samples was 7.5 times higher than that obtained by direct plating. The predominant serotypes of faecal C. jejuni, determined by serotyping with a set of 25 commercial antisera for heat-stable antigens (Penner), were Pen2 and Pen4-complex, which covered 52% of the samples. Genotyping with pulsed-field gel electrophoresis (PFGE) using SmaI restriction yielded a high diversity of C. jejuni subtypes in cattle. Determining the minimum inhibitory concentrations of ampicillin, enrofloxacin, erythromycin, gentamicin, nalidixic acid, and oxytetracycline among bovine C. jejuni isolates using a commercial broth microdilution method yielded 9% of isolates resistant to at least one of the antimicrobials examined. No multiresistant isolates were found among the bovine C. jejuni strains. The study of the shedding patterns of Campylobacter spp. among three Finnish dairy cattle herds included the examination of fresh faecal samples and tank milk samples taken five times, as well as samples from drinking troughs taken once during the one-year study. The semiquantitative enrichment method detected C. jejuni in 169 of the 340 faecal samples, mostly at low levels. In addition, C. jejuni was present in one drinking trough sample. The prevalence between herds and sampling occasions varied widely. PFGE, using SmaI as restriction enzyme, identified only a few subtypes in each herd. In two 2 of the herds, two subtypes persisted throughout the sampling. Individual animals presented various shedding patterns during the study. Comparison of C. jejuni isolates from humans, chickens and cattle included the design of primers for four new genetic markers selected from completely sequenced C. jejuni genomes 81-176, RM1221 and NCTC 11168, and the PCR examination of domestic human isolates from southern Finland in 1996, 2002 and 2003 (n=309), chicken isolates from 2003, 2006 and 2007 (n=205), and bovine isolates from 2003 (n=131). The results revealed that bovine isolates differed significantly from human and chicken isolates. In particular, the - glutamyl transpeptidase gene was uncommon among bovine isolates. The PFGE genotyping of C. jejuni isolates, using SmaI and KpnI restriction enzymes, included a geographically representative collection of isolates from domestic sporadic human infections, chicken slaughter batches, and cattle faeces and carcasses during the seasonal peak of campylobacteriosis in the summer of 2003. The study determined that 55.4% of human isolates were indistinguishable from those of chickens and cattle. Temporal association between isolates from humans and chickens was possible in 31.4% of human infections. Approximately 19% of the human infections may have been associated with cattle. However, isolates from bovine carcasses and human cases represented different PFGE subtypes. In conclusion, this study suggests that Finnish cattle is a notable reservoir of C. jejuni, the most important Campylobacter sp. in human enteric infections. Although the concentration of these organisms in bovine faeces appeared to be low, excretion can be persistent. The genetic diversity and presence or absence of marker genes support previous suggestions of host-adapted C. jejuni strains, and may indicate variations in virulence between strains from different hosts. In addition to chickens, Finnish cattle appeared to be an important reservoir and possible source of C. jejuni in domestic sporadic human infections. However, sources of campylobacters may differ between rural and urban areas in Finland, and in general, the transmission of C. jejuni of bovine origin probably occurs via other routes than food.

Essays on the Linkages Between Financial Markets, and Risk Asymmetries (summary section only)

During the last few decades there have been far going financial market deregulation, technical development, advances in information technology, and standardization of legislation between countries. As a result, one can expect that financial markets have grown more interlinked. The proper understanding of the cross-market linkages has implications for investment and risk management, diversification, asset pricing, and regulation. The purpose of this research is to assess the degree of price, return, and volatility linkages between both geographic markets and asset categories within one country, Finland. Another purpose is to analyze risk asymmetries, i.e., the tendency of equity risk to be higher after negative events than after positive events of equal magnitude. The analysis is conducted both with respect to total risk (volatility), and systematic risk (beta). The thesis consists of an introductory part and four essays. The first essay studies to which extent international stock prices comove. The degree of comovements is low, indicating benefits from international diversification. The second essay examines the degree to which the Finnish market is linked to the “world market”. The total risk is divided into two parts, one relating to world factors, and one relating to domestic factors. The impact of world factors has increased over time. After 1993, when foreign investors were allowed to freely invest in Finnish assets, the risk level has been higher than previously. This was also the case during the economic recession in the beginning of the 1990’s. The third essay focuses on the stock, bond, and money markets in Finland. According to a trading model, the degree of volatility linkages should be strong. However, the results contradict this. The linkages are surprisingly weak, even negative. The stock market is the most independent, while the money market is affected by events on the two other markets. The fourth essay concentrates on volatility and beta asymmetries. Contrary to many international studies there are only few cases of risk asymmetries. When they occur, they tend to be driven by the market-wide component rather than the portfolio specific element.

Service Productivity: Toward a Conceptualisation of the Transformation of inputs

The productivity of a process is related to how effectively input resources are transformed into value for customers. For the needs of manufacturers of physical products there are widely used productivity concepts and measurements instruments. However, in service processes the underlying assumptions of these concepts and models do not hold. For example, manufacturing-based productivity models assume that an altered configuration of input resources in the production process does not lead to quality changes in outputs (the constant-quality assumption). However, in a service context changes in the production resources and productions systems do affect the perceived quality of services. Therefore, using manufacturing-oriented productivity models in service contexts are likely to give managers wrong directions for action. Research into the productivity of services is still scarce, because of the lack of viable models. The purpose of the present article is to analyse the requirements for the development of a productivity concept for service operations. Based on the analysis, a service productivity model is developed. According to this model, service productivity is a function of 1) how effectively input resources into the service (production) process are transformed to outputs in the form of services (internal or cost efficiency), 2) how well the quality of the service process and its outcome is perceived (external or revenue efficiency), and 3) how effectively the capacity of the service process is utilised (capacity efficiency). In addition, directions for developing measurement models for service productivity are discussed.

What Determines Stock Option Contract Design?

This paper analyzes factors driving the design of stock option plans for Finnish firms. We examine determinants of the scope of plans, exercise price, target group, and dividend protection. The scope is found to be negatively related to Tobin’s Q and positively related to proxies for monitoring costs. The scope is also greater in broad-based plans, and in plans with dividend protection. Prior stock return is found to be negatively related to the size of the premium (out-of-the-moneyness), whereas dividend protection increases the premium. The results also suggest that investment intensity, cash flow, and monitoring costs are associated with the likelihood of granting premium (out-of-the-money) stock options. Furthermore, the likelihood of granting broad-based plans is increasing in institutional ownership and cash flow constraints, and decreasing in firm size. Broad-based plans are also more likely among firms in growth industries. We find support that the likelihood of dividend protection is decreasing in foreign ownership. In addition, firms paying zero-dividends are less likely to include dividend protection, whereas higher unsystematic risk is associated with a greater likelihood of including dividend protection.

Toksoplasman esiintyvyys suomalaisissa kissoissa

Toxoplasma gondii on kokkideihin kuuluva alkueläinloinen. Sen pääisäntiä ovat kissaeläimet, joissa tapahtuvan suvullisen lisääntymisen tuloksena tuotetaan ympäristöön ookystia. Väli-isäntiä voivat olla kaikki tasalämpöiset eläimet. Toksoplasma muodostaa isäntien kudoksiin infektiivisiä kudoskystia. Ihminen voi saada tartunnan syömällä kudoskystia tai ookystia, tai sikiö voi infektoitua jo kohdussa istukan kautta. Toxoplasma gondii voi aiheuttaa isäntänsä vakavan sairastumisen ja on siksi maailmanlaajuisesti merkittävä zoonoottinen loinen. Toksoplasman torjunnassa on oleellista tuntea alueen kissojen toksoplasmaseroprevalenssi ja arvioida ympäristön ookystakuormitusta: seropositiivisten kissojen voidaan olettaa joskus erittäneen ookystia. Tässä tutkimuksessa selvitettiin toksoplasman esiintymistä suomalaisissa kissoissa: suoralla agglutinaatiotestillä (ToxoScreen-DA) määritettiin IgG-vasta-aineiden esiintymistä seerumissa sekä vasta-ainetasoja (tiitteri). Flotac® - flotaatiomenetelmällä tutkittiin ookystien esiintymistä ulostenäytteissä. Tutkimuksessa selvitettiin kissojen toksoplasma-vasta-aineiden esiintymiseen vaikuttavia tekijöitä: serologisessa tutkimuksessa oli mukana sekä löytöettä rotukissoja, ja lisäksi tutkittiin kissojen sukupuolen, iän, sekä rotukissoilla lihansyönnin vaikutusta vastaaineiden esiintymiseen seerumissa. Serologisessa tutkimuksessa 398 kissan aineistossa seroprevalenssiksi saatiin 48,2 %. Tutkituista 369 rotukissasta 49,9 % oli seropositiivisia, kun taas 27 tutkitusta löytökissasta seropositiivisia oli 25,9 % (P<0,05). Sukupuolella ei todettu olevan merkitystä kissan seropositiivisuuteen. Aikuiset kissat olivat nuoria kissoja useammin seropositiivisia (53,7 % vs. 23,5 %) (P<0,001), koska kerran tartunnan saaneen kissan seerumista voidaan todeta vasta-aineita, ja vanhemmat kissat ovat nuoria todennäköisemmin ehtineet törmätä loiseen elämänsä aikana ja saada tartunnan. Ruokavalio oli tiedossa 347 rotukissalta, ja näistä 270 (77,8 %) oli joskus saanut raakaa lihaa. Raakaa lihaa saaneista kissoista 151 (55,9 %) oli seropositiivisia; 77 kissasta, jotka eivät olleet saaneet raakaa lihaa sitä vastoin ainoastaan 26 (33,8 %) oli seropositiivisia (P<0,001). Ulostenäytteistä 131 kissan aineistosta 1,5 % eritti toksoplasman kaltaisia ookystia ulosteessaan tutkimushetkellä. Suomessa kissojen ravinnon ja toksoplasmaseropositiivisuuden välistä yhteyttä ei ole aikaisemmin tutkittu. Näiden uusien tulosten valossa olisi toksoplasman torjunnassa erityisen tärkeää kiinnittää huomiota loisen tartuntareitteihin kissan osalta. Kissoja ei tulisi ruokkia raa’alla lihalla: kissalle annettava liha olisi hyvä kuumentaa yli 67ºC:een tai pakastaa alle -12ºC:n lämpötilassa toksoplasmatartunnan ehkäisemiseksi.

Kohti vähäpäästöistä liikennettä? Hiilidioksidipäästöihin perustuva autoverouudistus Helsingin Sanomissa

Suomessa uudistettiin vuoden 2008 alussa uuden henkilöauton oston yhteydessä maksettava autovero sekä vuosittainen ajoneuvovero hiilidioksidipäästöihin perustuviksi. Uudistuksen taustalla olivat Euroopan unionin tavoitteet hiilidioksidipäästöjen vähentämisestä sekä jäsenmaiden autoverotuksen yhdentämisestä. Uudistuksessa verojen määrät sidottiin auton ominaishiilidioksidipäästöihin (g/km) ja autoveron keskimääräistä tasoa laskettiin kuudenneksella. Tutkimuksessa tarkasteltiin auto- ja ajoneuvoverojen uudistuksista käytyä sanomalehtikeskustelua. Media vaikuttaa keskeisesti julkisen keskustelun aiheiden ja painotusten määrittelyyn sekä sosiaalisen todellisuuden rakentamiseen. Autoverouudistuksesta käyty sanomalehtikeskustelu antaa siis osviittaa siitä, miten uudistukseen suhtauduttiin ja minkälaisena liikenteen aiheuttamien ympäristöongelmien ratkaisukeinona se koettiin yhteiskunnassa. Tutkimuksen aineistoksi valikoitiin 131 Suomen laajalevikkisimmässä sanomalehdessä, Helsingin Sanomissa, julkaistua autoverouudistusta ja ympäristöaiheita käsittelevää artikkelia. Aineisto käsiteltiin sisällönanalyysillä, jossa aineisto luokiteltiin 67 muuttujan avulla. Lisäksi aineistosta tarkasteltiin laadullisia ominaisuuksia. Autoverouudistuksen suunnittelun ja toimeenpanon yhteydessä kirjoiteltiin paljon henkilöautojen päästöistä ja niiden vähentämisestä. Kirjoittelu jäi kuitenkin yleiselle tasolle, eikä eri päästöjä eroteltu tai päästöjen määriin vaikuttavia tekijöitä analysoitu. Autoverouudistus näyttäytyi Helsingin Sanomien artikkeleissa hyvin toimivana liikenteen aiheuttamien ympäristöongelmien hallintakeinona, vaikka uudistukseen liittyi sekä päästöjä vähentäviä että niitä lisääviä ominaisuuksia. Autoverouudistuksen näyttäytymiseen tehokkaana liikenteen päästöjen hallintakeinona vaikutti kirjoittelun keskittyminen lähitulevaisuuden vaikutuksiin, pitkän aikavälin seurausten jäädessä vähemmälle huomiolle. Keskustelua ei myöskään käyty kovin kokonaisvaltaisesti, sillä kirjoituksissa käsiteltiin lähinnä ihmisten toimintaan liittyviä aiheita ekologiseen ympäristöön kohdistuvien vaikutusten jäädessä vähälle huomiolle. Lisäksi käytyyn keskusteluun vaikutti valtiovarainministeriön menettely, jossa tietoja autoveron muuttamisesta ei annettu julkisuuteen lakimuutoksen valmistelun aikana. Tämä vähensi kansalaisten mahdollisuuksia esittää näkemyksiään tulevaan uudistukseen.
