Exploring two cases of Piano Teacher Education in Finland and Germany

Research about music instrument teacher education is scattered and fairly recent, especially in the European context. The purpose of this study was to explore two cases of piano teacher education programs at higher music education institutions, one in Finland, and one in Germany, to gain insights into the preparation of piano teachers for their professional working life. The aim was to identify issues for consideration in curriculum development of piano teacher education to enhance the teaching and learning of piano playing, and to ultimately increase musical practice and engagement among young learners. Nine semi-structured interviews with piano teacher educators, heads of program, other lecturers within the program, and student piano teachers in both cases were analyzed using applied thematic analysis. Three main themes with subcategories emerged: (1) the organization of the piano teacher education program, such as the structure, the content, the learning environments provided, and the development mechanisms of the program; (2) the views on the piano teacher profession, the working environment and resulting requirements, including further education during professional life; and (3) the professional skills and teacher identity development of student teachers. While the supposed working environments and requirements of future piano teachers, the student teachers' development characteristics, and the content were found reasonably concurrent in both cases, the structure of the teacher education program, and the organization of learning environments presented notable differences. While the complete teacher qualification in the Finnish case was offered as option in the Bachelor and Master of Music program within the piano department, the German case offered a separate program for music instrument educators. Other main differences concerned the organizations of practical teaching experiences, and the linking of practical with theoretical pedagogy. Conviction and enthusiasm for improving piano and other music instrument teacher education seemed remarkable. These improvements could include the development of a comprehensive teacher education pedagogy for music instrument teacher educators, intensified cross-linking within and of higher music education institutions in local contexts, and the expansion of professional development opportunities.

Diverse Routes from School, via Higher Education, to Employment. A Comparison of Nine European Countries

The central theme for this study is graduate employment and employability in European-wide discussion. In this study, the complex relationships between higher education and the world of work are explored from the vantage point of how individuals make use of the higher education system in their transition from education to employment. The variation among individual transition processes in nine European countries is analysed with the help of a comparable graduate survey. Countries in this study are Italy, Spain, France, Austria, Germany, the Netherlands, the United Kingdom, Finland, and Norway. The data used for the study is commonly known as the “CHEERS” or “Careers after Higher Education, A European Research Survey.” The data was collected in 1999. The study discusses the possibilities and limitations the higher education system has in supporting the initial education-to-work transitions of youth. The study also addresses problems with comparing national higher education systems in terms of enrolment and graduate employability. A central purpose for this study is to reflect on concerns about the prolongation of individual transitions with a framework that simultaneously considers both the graduate employability and the duration of the education-to-work transition process. The key concept for this study is the standard student/graduate; synonym concepts are the traditional and the conventional student/graduate. Standard graduates are relatively young individuals who are performing their initial transition from education to working-life and who complete the degree-earning process within the stipulated time frame. In all nine countries, standard graduates make up a considerable share of the student flow, passing from higher education to the labour markets. The share of standard graduates is by far the largest in France, where they comprise the overwhelming mass. The proportion of the standard graduates is the lowest in Italy, Finland, and Austria where approximately one in four graduates completed the process of higher education within the stipulated time frame. Of the nine countries compared, employability of the whole graduate population is the greatest in Norway, the UK, Finland, and the Netherlands. Compared with employability of the whole graduate population, variation among the countries is considerably reduced when reviewing the employability of only the standard graduates. Thereby, even though the ranking among countries remains largely unchanged, the variations among them are smaller when the duration of degree earning process is standardized. The study also discusses other ideal types of student careers (or transition processes) besides the standard student/graduate. Results of regression analyses indicate that that at the pan-European level analysis, the graduate labour markets are not heavily segmented in terms of the type of the individual transition process. When considering within-country differences between the graduates, the field of studies is clearly a more powerful explanatory variable than the type of the transition process. There are, nevertheless, clear indications that, irrespective of the country, chances of finding a high status job are, on the average, highest amongst those who graduate within the stipulated duration of the degree program and who thereby have experienced the standard student career, whereas, participating in working life while studying protects against unemployment after finishing one’s degree.

Bordetella pertussis - Vaccination and Strain Variation

Pertussis or whooping cough is a highly contagious vaccine-preventable disease of the human respiratory tract caused by the Bordetella pertussis bacteria. In Finland, pertussis vaccinations were started in 1952 leading to a dramatic decrease in the morbidity and mortality. In the late 1990s, the incidence of pertussis increased despite the high vaccination coverage. Strain variation has been connected to the re-emergence of pertussis in countries with long history of pertussis vaccination. In 2005, the pertussis vaccine and the vaccination schedule were changed in Finland. The molecular epidemiology and the strain variation of the B. pertussis isolates were examined in Finland and in countries with similar (France) and different (Sweden) vaccination history. Continuous evolution of the B. pertussis population in Finland was observed since the 1950s, and the recently circulating isolates were antigenically different from the vaccine strains. Comparison of the circulating isolates from Finland, France and Sweden did not refer to significant differences. Certain type of strains noticed in France already in 1994 mainly caused the recent epidemics in Sweden (1999) and in Finland (2003-4). On several occasions, a new type of strains first appeared in Sweden and some years later in Finland. The B. pertussis isolates from the infants were shown to be similar to those from the other age groups. It is suggested that the strains originate from the same reservoir among adolescents and adults. The strain variation does not seem to have a major effect on the morbidity among recently vaccinated individuals, but it might play a role among those who are in the waning phase of immunity. The incidence of pertussis in Finland has remained low since the change of the vaccination programme. This might be related to the epidemic nature of pertussis and the near future will show the real effectiveness of the new vaccination programme. At present, many infants are infected because they are too young to be immunised with the current schedule. New strategies or vaccines are needed to protect those who are the most vulnerable.

Integrating distributed generation and Smart Grids into single-family house

This study examines Smart Grids and distributed generation, which is connected to a single-family house. The distributed generation comprises small wind power plant and solar panels. The study is done from the consumer point of view and it is divided into two parts. The first part presents the theoretical part and the second part presents the research part. The theoretical part consists of the definition of distributed generation, wind power, solar energy and Smart Grids. The study examines what the Smart Grids will enable. New technology concerning Smart Grids is also examined. The research part introduces wind and sun conditions from two countries. The countries are Finland and Germany. According to the wind and sun conditions of these two countries, the annual electricity production from wind power plant and solar panels will be calculated. The costs of generating electricity from wind and solar energy are calculated from the results of annual electricity productions. The study will also deal with feed-in tariffs, which are supporting systems for renewable energy resources. It is examined in the study, if it is cost-effective for the consumers to use the produced electricity by themselves or sell it to the grid. Finally, figures for both countries are formed. The figures include the calculated cost of generating electricity from wind power plant and solar panels, retail and wholesale prices and feed-in tariffs. In Finland, it is not cost-effective to sell the produced electricity to the grid, before there are support systems. In Germany, it is cost-effective to sell the produced electricity from solar panels to the grid because of feed-in tariffs. On the other hand, in Germany it is cost-effective to produce electricity from wind to own use because the retail price is higher than the produced electricity from wind.

Organisational learning and knowledge acquisition. A case study of internationalising manufacturers of wood-based prefabricated buildings

The study investigates organisational learning and knowledge acquisition of wood-based prefabricated building manufacturers. This certain group of case companies was chosen, because their management and their employees generally have a strong manufacturing and engineering background, while the housing sector is characterised by national norms, regulations, as well as local building styles. Considering this setting, it was investigated, how the case companies develop organisational learning capabilities, acquire and transfer knowledge for their internationalisation. The theoretical framework of this study constitutes the knowledge-based conceptualisation of internationalisation, which combines the traditional internationalisation process, as well as the international new venture perspective based on their commonalities in the knowledge-based view of the firm. Different theories of internationalisation, including the network-perspective, were outlined and a framework on organisational learning and knowledge acquisition was established. The empirical research followed a qualitative approach, deploying a multiple-case study with five case companies from Austria, Finland and Germany. In the study, the development of the wood-based prefabricated building industry and of the case companies are described, and the motives, facilitators and challenges for foreign expansion, as well as the companies’ internationalisation approaches are compared. Different methods of how companies facilitate the knowledge-exchange or learn about new markets are also outlined. Experience, market knowledge and personal contacts are considered essential for the internationalisation process. The major finding of the study is that it is not necessary to acquire the market knowledge internally in a slow process as proposed by the Uppsala model. In four cases companies engaged knowledge in symbiotic relations with local business partners. Thereby, the building manufacturers contribute their design and production capabilities, and in return, their local partners provide them with knowledge about the market and local regulations; while they manage the sales and construction operations. Thus, the study provides strong evidence for the propositions of network perspective. One case company developed the knowledge internally in a gradual process: it entered the market sequentially with several business lines, showing an increasing level of complexity. In both of the observed strategies, single-loop and double-loop learning processes occurred.

The role of emotional state, sexual arousal, and alcohol intoxication as situational factors associated with adults’ online sexual contact with children and adolescents

In the present study we explored whether and how the situational factors; emotional states, sexual arousal, and alcohol intoxication influenced the propensity in adults to engage in online sexual contact with children (13 or younger) and adolescents (14 – 17 year olds). The results were compared to a group of adults that had engaged in online sexual contact with adults only (18 or older). We also looked at the variation over time within these situational factors during the online sexual contact with a child, an adolescent, or an adult. The present study was an online self-report survey to the adult populations in Finland, Sweden, and Germany, with a final sample (N = 776) of women and men who were active on the Internet. The participants were asked to report whether, how, and with whom they had engaged in online sexual contact. The results showed that more men than women reported online sexual contact with persons of all age groups, and that the situational factors; emotional states and sexual arousal influenced the propensity in both women and men to engage in online sexual contact with children and adolescents. However, the effects of alcohol intoxication were small and significant only for men. These results indicate that higher levels of emotional state and sexual arousal might increase the propensity to go against social norms and contact children and adolescents online for sexual purposes, but it can also imply that that those who look for online sexual contact online with children and adolescents, are more emotionally and/or sexually aroused than the group that only seek adult company or that these are post-hoc explanations for such sexual activities.

Analyzing and Computing the Sustainability Gains of Building Automation

Smart home implementation in residential buildings promises to optimize energy usage and save significant amount of energy simply due to a better understanding of user's energy usage profile. Apart from the energy optimisation prospects of this technology, it also aims to guarantee occupants significant amount of comfort and remote control over home appliances both at home locations and at remote places. However, smart home investment just like any other kind of investment requires an adequate measurement and justification of the economic gains it could proffer before its realization. These economic gains could differ for different occupants due to their inherent behaviours and tendencies. Thus it is pertinent to investigate the various behaviours and tendencies of occupants in different domain of interests and to measure the value of the energy savings accrued by smart home implementations in these domains of interest in order to justify such economic gains. This thesis investigates two domains of interests (the rented apartment and owned apartment) for primarily two behavioural tendencies (Finland and Germany) obtained from observation and corroborated by conducted interviews to measure the payback time and Return on Investment (ROI) of their smart home implementations. Also, similar measures are obtained for identified Australian use case. The research finding reveals that building automation for the Finnish behavioural tendencies seems to proffers a better ROI and payback time for smart home implementations.

Suomen taloussuhdanteiden kansainvälinen yhteisvaihtelu

Taloussuhdanteiden yhteisvaihtelun tutkimus on eräs taloustieteiden vanhimmista tutkimusaloista. Finanssikriisi ja euroalueen kohtaamat talousvaikeudet ovat kuitenkin nostaneet aiheen jälleen hyvin ajankohtaiseksi. Kuluneiden kahdenkymmenen vuoden aikana tutkimusalueesta on muodostunut erittäin laaja lukuisine näkökulmineen ja debatteineen. Tutkielman aiheena on Suomen taloussuhdanteiden kansainvälinen yhteisvaihtelu valittujen vertailumaiden kanssa. Vertailumaat ovat Ruotsi, Norja, Tanska, Saksa, Ranska, Iso-Britannia ja Yhdysvallat. Tutkielmaan valitut taloussuhdannetta kuvaavat muuttujat ovat reaalinen bruttokansantuote, yksityinen kokonaiskulutus ja teollisuustuotantoindeksi. Aineisto on kerätty Lappeenrannan tiedekirjaston Nelli-portaalin OECD iLibrary-tietokannasta ja se kattaa aikajakson 1960 Q1- 2014 Q4. Maakohtainen taloussuhdanne operationalisoidaan laskemalla ensimmäinen logaritminen differenssi, joka edustaa perinteistä reaalisuhdanneteoreettisen koulukunnan näkemystä taloussuhdanteesta. Tutkielman näkökulmaksi valitaan yhden maan näkökulma, joka on hieman harvinaisempi näkökulma verrattuna laajempiin alueellisiin näkökulmiin. Tutkimusmenetelminä käytetään Pearsonin korrelaatiokerrointa, Engle-Granger- sekä Johansenin yhteisintegroituvuustestejä ja VAR-GARCH-BEKK –mallilla laskettua dynaamista korrelaatiota, jotka lasketaan Suomen ja vertailumaiden välille maapareittain. Tuloksia tulkitaan suomalaisen vientiä vertailumaihin suunnittelevan yrityksen näkökulmasta. Tutkielman tulosten perusteella Engle-Grangerin menetelmällä laskettu samanaikainen yhteisintegroituvuus Suomen ja vertailumaiden välillä on epätodennäköistä. Kun yhteisintegroituvuuden annetaan riippua myös viiveistä, saadaan Johansenin menetelmällä yhteisintegroituvuus Suomen ja Yhdysvaltojen välille reaalisessa bruttokansantuotteessa, Suomen ja Saksan, Suomen ja Ranskan sekä Suomen ja Yhdysvaltojen välille yksityisessä kokonaiskulutuksessa sekä Suomen ja Norjan välille teollisuustuotantoindeksissä. Tulosten tulkintaa vaikeuttavat niiden malliriippuvuus ja informaatiokriteerien toisistaan poikkeavat mallisuositukset, joten yhteisintegroituvuus on mahdollinen myös muiden maaparien kohdalla. Dynaamisten korrelaatiokuvaajien perusteella maaparien välisen yhteisvaihtelun voimakkuus muuttuu ajan mukana. Finanssikriisin aikana kokonaistuotannossa on havaittavissa korkeampi korrelaatio, mutta korrelaatio palaa sen jälkeen perustasolleen. Kokonaiskulutuksen korrelaatio on kokonaistuotantoa alhaisempi ja pitemmissä aikajaksoissa vaihtelevaa.

Parhaat käyttökelpoiset tekniikat (BAT) perunankuorimoiden jätteiden käsittelyssä -käytäntöjä Euroopan maista

Yhä suurempi osa suurkeittiöistä ja ravintoloista käyttää ruuan valmistuksessa valmiiksi prosessoituja kasviksia, jotka hankitaan pääasiassa lähellä sijaitsevista tilakuorimoista. Kuorimoilla syntyy suuria määriä jätettä, enimmäkseen kuorijätteitä, multaa ja jätevettä. Tässä työssä tarkastellaan perunankuorimoiden kuorintamenetelmiä ja kuorintaprosessia, prosessissa syntyviä jätteitä ja niiden käsittelyä sekä ympäristöasioiden hallintamenetel-miä kuorimoilla Suomessa ja muissa EU-maissa. Työn tavoitteena oli selvittää, minkälainen on lainsäädäntö ja minkälaiset ovat kuorimotoimintaa koskevat lupakäytännöt Ruotsissa, Saksassa, Belgiassa ja Iso-Britanniassa. Lisäksi tavoitteena oli selvittää, onko näissä maissa määritelty, millainen on perunankuorimoille soveltuva paras käyttökelpoinen tekniikka (BAT) erityisesti jätteiden käsittelyssä. Euroopan yhteisön neuvoston direktiivi (96/61/EY) ympäristön pilaantumisen ehkäisemisen ja vähentämisen yhtenäistämiseksi edellyttää perunankuorimoilta toimintaansa ympäristöluvan. Laitosten koko, joilta ympäristölupa vaaditaan, vaihtelee suuresti eri maissa. Myös kuorimoiden jäteveden puhdistusvaatimukset vaihtelevat maittain. Belgi-assa ja Saksassa perunankuorimoilla syntyville jätevesille on asetettu päästöraja-arvot laissa. Kansallinen BAT-ohjeistus vihanneksia ja hedelmiä jatkojalostavalle teollisuudelleon tehty Belgiassa ja Iso-Britanniassa. Sen sijaan Saksassa ja Ruotsissa kansallista ohjeistusta ei ole tehty. Kansallisten BAT-ohjeistusten pohjalta Euroopan yhteisöjen komissio on julkaissut tammikuussa 2006 elintarviketeollisuudelle BAT-vertailuasiakirjan eli BREFin (BAT Referense Document), joissa kuvataan yleisellä tasolla BAT-tekniikoiksi sovitut tekniikat mm. perunan prosessoinnissa. Tässä työssä tuli ilmi, että kokoerot Suomen ja tässä työssä tarkasteltavien maiden kuo-rimoiden välillä ovat suuret. Voidaankin todeta, että tässä työssä tarkastelluissa BAT - ohjeistuksissa ja Euroopan komission BREF-dokumentissa esitetyt BAT-tekniikat etenkin jätevedenpuhdistuksessa eivät suoraan ole sovellettavissa Suomen olosuhteisiin kuorimoidemme pienestä koosta johtuen. Kiinteiden kuorintajätteiden käsittelyssä BAT-tekniikoiksi ulkomailla on määritelty lä-hinnä rehukäyttö, kompostointi ja peltoon levitys. Perunankuorimoiden jäteveden puhdistuksessa BAT-tekniikaksi Belgiassa on määritelty primääripuhdistus ja sekundääripuhdistus aerobisella menetelmällä. Iso-Britanniassapuolestaan BAT-tekniikkaa on primää-ripuhdistus, sekundääripuhdistus aerobisesti tai anaerobisesti ja tertiääripuhdistus, mikäli se on taloudellisesti mahdollista toteuttaa. Kuorijätteiden kompostointi on tällä hetkelläSuomessa melko harvinaista, sillä jätteiden suuri vesipitoisuus ja kylmä ilmastomme vaikeuttavat kompostointia. Kompostointimah-dollisuuksia ja kompostointiprosessin optimointia kuorintajätteille sopivaksi tulisikin tutkia tulevaisuudessa yhtenä jätteiden käsittelyvaihtoehtona. Kuorimoiden jätevesien puhdistuksessa tulevat Suomessa kysymykseen lähinnä yksinkertaiset kiinteistökohtaiset pienpuhdistamot, kuten panospuhdistamot. Pienpuhdistamolaitteistoihin liittyvää tutki-mus-ja kehitystyötä on viime vuosina tehty paljon ja sitä olisi tärkeää jatkaa edelleen, jotta löydettäisiin entistä kustannustehokkaampia ratkaisuja.

Factors Affecting the Forecasting Accuracy of Diffusion Models

Tutkielman tavoitteena oli tarkastella innovaatioiden leviämismallien ennustetarkkuuteen vaikuttavia tekijöitä. Tutkielmassa ennustettiin logistisella mallilla matkapuhelinliittymien leviämistä kolmessa Euroopan maassa: Suomessa, Ranskassa ja Kreikassa. Teoriaosa keskittyi innovaatioiden leviämisen ennustamiseen leviämismallien avulla. Erityisesti painotettiin mallien ennustuskykyä ja niiden käytettävyyttä eri tilanteissa. Empiirisessä osassa keskityttiin ennustamiseen logistisella leviämismallilla, joka kalibroitiin eri tavoin koostetuilla aikasarjoilla. Näin tehtyjä ennusteita tarkasteltiin tiedon kokoamistasojen vaikutusten selvittämiseksi. Tutkimusasetelma oli empiirinen, mikä sisälsi logistisen leviämismallin ennustetarkkuuden tutkimista otosdatan kokoamistasoa muunnellen. Leviämismalliin syötettävä data voidaan kerätä kuukausittain ja operaattorikohtaisesti vaikuttamatta ennustetarkkuuteen. Dataan on sisällytettävä leviämiskäyrän käännöskohta, eli pitkän aikavälin huippukysyntäpiste.
