Nikkelille selektiivisen kelatoivan adsorbenttimateriaalin valmistus ja tutkiminen

Metallien laajamittaisen ja runsaan käytön vuoksi nykyään on keskityttävä aikaisempaa tarkemmin metallipäästöjen estämiseen ja puhdistamiseen. Metallien puhdistamiseen jätevesistä voidaan käyttää erilaisia yksikköoperaatiomenetelmiä, mutta selektiivisempään erotukseen päästään ioninvaihto- ja adsorbenttimateriaaleilla. Työn tarkoitusena on valmistaa ja tutkia nikkeliselektiivisiä adsorbenttimateriaaleja. Lisäksi tutkimuskohteena on nikkelin ja 1,10-fenantroliinin välisen kompleksin muodostuminen eri pH-arvoilla. Selektiivisten adsorbenttimateriaalien valmistaminen onnistuu liittämällä kiinteään kantajaan ligandi. Tämän työn tapauksessa nikkelitemplaatin liittäminen kiinteään kantajaan funktionalisointivaiheessa muodostaa adsorbenttiin nikkelille spesifisen kohdan. Käytännössä spesifisyyden syntyminen ei ole itsestäänselvyys, vaan se riippuu paljon funktionalisointitavasta. Tässä työssä funktionalisointitapana olivat fysikaalinen adsorptio ja impregnointi. Nikkelin ja 1,10-fenantroliinin välisen kompleksin muodostumista tutkittiin eri pH-arvojen lisäksi neljällä eri happokonsentraatiolla. Tuloksia verrattiin sellaisen liuoksen spektriin, missä oli pelkkää nikkeliä. Tuloksista havaittiin, että komplekseja muodostuu käytännössä samalla tavalla pH:n ollessa 1–6. Vasta 5 M HNO3 alkoi heikentää kompleksien muodostumista, ja 10 M HNO3 esti kompleksien muodostumisen täysin. Adsorbenttimateriaaleja valmistettiin useita erilaisia, joihin osaan liitettiin nikkelitemplaatti ja osa jätettiin ilman templaattia. Työssä keskityttiin tutkimaan erityisesti kolmea silikasta valmistettua materiaalia, joissa vain kahdessa oli nikkelitemplaatti. Nikkelitemplaattien olemassaololla ei havaittu olevan juurikaan merkitystä nikkelin erottamiseen vesiliuoksista. Materiaaleille tehdyt regenerointikokeet osoittivat, että materiaalien toiminta ja kapasiteetti eivät olleet toivotulla tasolla.

Social media and public libraries : exploring information activities of library professionals and users

Social media has become a part of many people’s everyday lives. In the library field the adoption of social media has been widespread and discussions of the development of “Library 2.0” began at an early stage. The aim with this thesis is to study the interface between public libraries, social media, and users, focusing on information activities. The main research question is: How is the interface between public libraries and social media perceived and acted upon by its main stakeholders (library professionals and users)? The background of Library 2.0 is strongly associated with the development of the Web and social media, as well as with the public libraries and their user-centered and information technological development. The theoretical framework builds on the research within the area of Library and Information Science concerning information behavior, information practice, and information activities. Earlier research on social media and public libraries is also highlighted in this thesis. The methods survey and content analysis were applied to map the interface between social media and public libraries. A questionnaire was handed out to the users and another questionnaire was sent out to the library professionals. The results were statistically analyzed. In the content analysis public library Facebook pages were studied. All the empirical investigations were conducted in the area of Finland Proper. An integrated analysis of the results deepens the understanding of the key elements of the social media and public library context. These elements are interactivity, information activities, perceptions, and stakeholders. In this context seven information activities were distinguished: reading, seeking, creating, communicating, informing, mediating, and contributing. This thesis contributes to develop the research concerning information activities and draws a realistic picture of the challenges and opportunities in the social media and public library context. It also contributes with knowledge on library professionals and library users, and the existing differences in their perceptions of the interface between libraries and social media.

Improving internal performance of a company - Introducing employee empowerment via job redesign in Finnish small and medium sized enterprises

This bachelor's thesis is about to find out to what extent Finnish managers and small and medium sized organizations are willing and able to put employee empowerment into practice and what experiences they have got from employee empowerment as an approach towards job redesign. Some of the top enterprises in the world are known for their empowered employees as a single most important factor for their success and this thesis focuses on introducing the subject to Finnish managers and organizations to find out what benefits, barriers and other thoughts they have about the whole idea of empowered employees in Finnish organization culture. Most notable findings in this thesis are that Finnish managers do think that their organization's employees are capable to work efficiently if their job is extended and the organizations would perform better when right person's job is enriched and he/she is given more power to solve problems.

Growth inhibitors in turfgrass

Well-maintained lawns are comfortable and safe places for leisure activities and sports practice, and they also bring environmental benefits; for example, they reduce soil exposure to erosion and releases atmospheric CO2, thus reducing the greenhouse effect. However, regardless of the purpose of use or the choice of the plant species to form the lawn, the highest costs involve cutting that is needed to keep the turfgrass at its appropriate height. Successive lawn cutting operations are necessary basically because of the vegetative and reproductive growth of turfgrass which, in Brazil, occurs mainly from October to March. Expenditures with successive mechanical cuttings have fostered the search of alternative procedures to keep lawn plants at appropriate height, such as the use of plant growth inhibitors, an increasingly interesting procedure. Since the use of this technology in Brazil is still at its early stage, the aim of this literature review is to examine aspects associated with lawn management by using growth inhibitors. Another alternative is to increase the knowledge of the classification and rational application of the different compounds currently available in the market.

Conditions and practices in the commercialisation of innovations in wood industry

The report 'Conditions and practices in the commercialisation of innovation in wood industry' has been written as a part of the Wood Academy project. The report analyses the commercialisation conditions and practices of wood industry by utilising product categorisation based on a conceptual schema which combines the aspects of the transfer of the procession of utility and the degree of form/service utility (or value-added) created or provided by the company. Open innovation approaches help to perceive the possible new product and service innovations as well as the new business models and earning logics in the industry. The report also contains brief company cases to demonstrate theory-to-practice and showcase company examples from successful Finnish companies.

Optimization and Measuring Techniques for Collect-and-Place Machines in Printed Circuit Board Industry

This thesis considers optimization problems arising in printed circuit board assembly. Especially, the case in which the electronic components of a single circuit board are placed using a single placement machine is studied. Although there is a large number of different placement machines, the use of collect-and-place -type gantry machines is discussed because of their flexibility and increasing popularity in the industry. Instead of solving the entire control optimization problem of a collect-andplace machine with a single application, the problem is divided into multiple subproblems because of its hard combinatorial nature. This dividing technique is called hierarchical decomposition. All the subproblems of the one PCB - one machine -context are described, classified and reviewed. The derived subproblems are then either solved with exact methods or new heuristic algorithms are developed and applied. The exact methods include, for example, a greedy algorithm and a solution based on dynamic programming. Some of the proposed heuristics contain constructive parts while others utilize local search or are based on frequency calculations. For the heuristics, it is made sure with comprehensive experimental tests that they are applicable and feasible. A number of quality functions will be proposed for evaluation and applied to the subproblems. In the experimental tests, artificially generated data from Markov-models and data from real-world PCB production are used. The thesis consists of an introduction and of five publications where the developed and used solution methods are described in their full detail. For all the problems stated in this thesis, the methods proposed are efficient enough to be used in the PCB assembly production in practice and are readily applicable in the PCB manufacturing industry.

Suomen mahdollisuudet vaikuttaa Euroopan unionin lainsäädäntömenettelyyn

Väitöstutkimuksen kohteena on säädösten valmistelu ja niitä koskevaa päätöksenteko Euroopan unionissa erityisesti siitä näkökulmasta, miten Suomen kaltainen pieni jäsenvaltio voi vaikuttaa EU-säädöksiin. Väitöskirjassa analysoidaan unionin toimielinten välillä vallitsevaa dynamiikkaa ja Suomen asemaa erityisesti EUT-sopimuksen 289 artiklan 1 kohdan ja 294 artiklan mukaisessa tavallisessa lainsäätämisjärjestyksessä. Lissabonin sopimuksen voimaantulon jälkeen tavallinen lainsäätämisjärjestys, joka aiemmin tunnettiin yhteispäätösmenettelynä, on selvästi yleisin lainsäädäntömenettely unionissa. Väitöskirja koostuu kuudesta erillisjulkaistusta pääosin vertaisarvioidusta artikkelista ja niitä täydentävästä ja kokoavasta yhteenveto-osasta. Kirjan tämä painos sisältää vain yhteenvetoluvun, ei erikseen julkaistuja artikkeleita. Väitöskirjassa hyödynnetään eurooppaoikeuden ja politiikan tutkimuksen kirjallisuutta. Metodologisesti väitöstutkimus edustaa empiiristä oikeustutkimusta, jossa yhdistyy lainopillinen analyysi ja empiiristen, tässä tapauksessa lähinnä laadullisten aineistojen analyysi. Yhteenvedossa on seurattu lainsäädäntömuutoksia ja oikeuskäytäntöä 10. huhtikuuta 2015 asti. Väitöskirjatutkimuksen kantavana teemana on oikeuden ja politiikan suhde EUlainsäätämisessä. Artikkeleita ja yhteenvetoa sitovat yhteen kaksi yleisen tason argumenttia. Ensiksi, EU:n lainsäädäntömenettelyä koskevat oikeussäännöt ja institutionalisoituneet käytännöt luovat kehikon toimielinten sisäiselle päätöksenteolle sekä niiden välisille poliittisluonteisille neuvotteluille, vaikkakaan sääntöihin ja käytäntöihin ei yleensä ole tarvetta nimenomaisesti vedota menettelyn kuluessa. Toiseksi, koska Suomen kaltaisen pienen jäsenvaltion muodollinen valta – siis äänimäärä neuvostossa – on hyvin rajallinen, suomalaisten ministerien ja virkamiesten tulisi hyödyntää erilaisia epävirallisia vaikuttamiskanavia, jos halutaan vahvistaa Suomen tosiasiallista vaikutusvaltaa menettelyssä. Unionin lainsäädäntötoiminta ei tyypillisesti ole rationaalisen mallin mukaan etenevää päätöksentekoa, vaan tempoilevaa ja vaikeasti ennakoitavaa kamppailua eri preferenssejä edustavien toimijoiden välillä. Väitöskirjan ensimmäisessä artikkelissa analysoidaan säädösvalmistelua ja lainsäätämismenettelyä unionissa vaihe vaiheelta. Johtopäätöksenä todetaan, että unioniin on syntynyt yhteispäätösmenettelyn, sittemmin tavallisen lainsäätämisjärjestyksen myötä uudenlainen lainsäätämiskulttuuri, jolle on leimallista tiiviit yhteydet komission, Euroopan parlamentin ja neuvoston välillä. Toimielimet ottavat nykyisin joustavasti huomioon toistensa kantoja menettelyn edetessä, mikä mahdollistaa sen, että valtaosa EU-säädöksistä voidaan hyväksyä jo ensimmäisessä käsittelyssä. Toisessa tutkimusartikkelissa analysoidaan komission asemaa unionin toimielinrakenteessa. Artikkelissa tarkastellaan komission aloiteoikeutta sekä komission puheenjohtajan ja sen jäsenten valintamenettelyjä siitä näkökulmasta, edistääkö komissio todella unionin yleistä etua itsenäisenä ja riippumattomana, kuten EU-sopimuksen 17 artiklassa edellytetään. Tiettyjen järjestelyjen myötä Euroopan parlamentin ja komission suhde on kehittynyt siihen suuntaan, että komissio toimii jossain määrin parlamentille vastuunalaisena hallituksena. Artikkelissa kritisoidaan, että kehitys ei välttämättä lähennä kansalaisia unionin toimielimiin ja että kehitys omiaan vaarantamaan komission aseman verrattain riippumattomana välittäjänä trilogeissa. Kolmas artikkeli sisältää tapaustutkimuksen kuluttajille myönnettäviä luottoja sääntelevän direktiivin (2008/48/EY) valmisteluvaiheista. Tapaustutkimus konkretisoi Suomen hallituksen edustajien tekemän EU-vaikuttamisen keinoja, vahvuuksia ja kehittämiskohteita. Artikkelissa todetaan, että Suomelle aivan keskeinen vaikuttamisresurssi ovat sellaiset virkamiehet, jotka hallitsevat niin käsiteltävän säädöshankkeen sisältökysymykset kuin unionin päätöksentekomenettelyt ja toimielinten institutionalisoituneet käytännöt. Artikkelissa tehdyt empiiriset havainnot jäsenvaltioiden välillä käydyistä neuvotteluista tukevat konstruktiivisen mallin perusoletuksia. Neljännessä artikkelissa, joka on laadittu yhteistyönä professori Tapio Raunion kanssa, analysoidaan unioniasioiden kansallista valmistelua ja tarkemmin ottaen sitä, miten Suomen neuvottelukannat muotoutuvat valtioneuvoston yhteensovittamisjärjestelmän ylimmällä tasolla EU-ministerivaliokunnassa. Artikkelissa todetaan laajan pöytäkirja-aineiston ja sitä täydentävän haastatteluaineiston pohjalta, että EUministerivaliokunnan asialistan laadinta on delegoitu kokonaisuudessaan asiantuntijavirkamiehille. Lisäksi asialistan muotoutumiseen vaikuttaa luonnollisesti unionin toimielinten, erityisesti Eurooppa-neuvoston agenda. Toisaalta, EU-ministerivaliokunnan kokouksissa ministerit yksin tekevät päätöksiä ja linjaavat Suomen EU-politiikkaa. Viidennessä artikkelissa selvitetään, miten olisi toimittava, jos pyritään siihen, että uusi tai muutettu EU-säädös vastaisi mahdollisimman pitkälti Suomen kansallisesti määriteltyä neuvottelukantaa. Tehokkainta on vaikuttaa aloiteoikeutta lainsäädäntömenettelyssä käyttävään komissioon, tarvittaessa myös virkahierarkian ylimmillä tasoilla, sekä tehdä yhteistyötä muiden jäsenvaltioiden kanssa, erityisesti puheenjohtajavaltion, tulevien puheenjohtajavaltioiden ja suurten jäsenvaltioiden kanssa. Mikäli käsittelyssä oleva EU-säädöshanke arvioidaan kansallisesti erityisen tärkeiksi tai ongelmalliseksi, tulisi vaikuttamistoimia laajentaa kattamaan myös Euroopan parlamentin avainhenkilöitä. Kuudennessa artikkelissa analysoidaan suomalaisen kansalaisyhteiskunnan ja etujärjestöjen vaikutusmahdollisuuksia EU-asioiden valmistelussa. Johtopäätöksenä todetaan, että muodollinen yhteensovittaminen EU-valmistelujaostojen laajan kokoonpanon kokouksissa ei ole sidosryhmille ensisijainen eikä tehokkain vaikuttamisen keino. Sen sijaan korostuvat epäviralliset yhteydet toimivaltaisen ministeriön vastuuvirkamieheen kotimaassa ja vaikuttaminen eurooppalaisen kattojärjestön välityksellä. Väitöskirjan yhteenveto-osassa on eritelty, missä EU:n säädösvalmistelun ja lainsäätämismenettelyn vaiheissa Suomen kaltaisella pienellä jäsenvaltiolla on parhaat edellytykset vaikuttaa valmisteltavana olevaan säädökseen. Parhaat vaikutusmahdollisuudet ovat aivan EU-säädöksen elinkaaren alkuvaiheessa, kun komissio on vasta käynnistämässä uutta säädösvalmistelua. Väitöstutkimuksessa todetaan, että varhaista kannanmuodostusta ja sen mahdollistamaa ennakkovaikuttamista on Suomessa kyetty kehittämään etenkin niissä poliittisesti, taloudellisesti tai oikeudellisesti tärkeissä hankkeissa, joissa hallituksen kannanmuodostus tapahtuu EU-ministerivaliokunnassa. Muissa unionin säädöshankkeissa ennakollisen vaikuttamisen intensiteetti näyttäisi vaihtelevan, riippuen muun muassa toimivaltaisen ministeriön keskijohdon ja ylimmän johdon sitoutumisesta. Toinen Suomelle otollinen vaikuttamisen ajankohta on silloin, kun komission antamaa ehdotusta käsitellään asiantuntijavirkamiesten kesken neuvoston työryhmässä. Tehokas vaikuttaminen edellyttää, että Suomea neuvotteluissa edustavat henkilöt kokoavat ”samanmielisistä” jäsenvaltioista kaksoisenemmistösäännön mukaisen voittavan koalition. Viimeinen vaikuttamisen ikkuna aukeaa silloin, kun Coreper-komiteassa laaditaan neuvoston puheenjohtajalle neuvottelumandaattia toimielinten välisiin trilogeihin tavallisen lainsäätämisjärjestyksen ensimmäisessä käsittelyssä. Tässä varsin myöhäisessä menettelyvaiheessa vaikuttaminen on pienen jäsenvaltion näkökulmasta jo selvästi vaikeampaa. Väitöskirja sijoittuu luontevasti osaksi valtiotieteellistä eurooppalaistumis-kirjallisuutta siltä osin, kuin siinä on tutkittu EU-jäsenyyden vaikutuksia kotimaisiin hallinnon rakenteisiin ja politiikan asialistaan. Kuten tunnettua, Suomen EU-politiikka rakentuu eduskunnalle vastuullisen valtioneuvoston varaan. Väitöskirjassa ei kuitenkaan ole otettu erityiseen tarkasteluun perustuslakiin sidottua eduskunnan ja hallituksen yhteistoimintaa EU-asioissa. Sen sijaan on tutkittu unioniasioiden valmistelua ja yhteensovittamista valtioneuvoston sisällä. Kun EU-asioiden yhteensovittamisjärjestelmää luotiin, pidettiin tärkeänä, että jokaisessa säädöshankkeessa ja politiikkahankkeessa kyetään muodostamaan kansallisesti yksi ja yhtenäinen neuvottelupositio. Yhtenäisen kansallisen linjan ajamisen katsottiin parantavan Suomen asemaa unionin päätöksenteossa. Väitöskirjassa todetaan johtopäätöksenä, että EU-asioiden kansallinen valmistelujärjestelmä toteuttaa sille asetetut tavoitteet käytännössä varsin hyvin. Merkittävin kehittämiskohde liittyy kansallisen EU-valmistelun reaktiivisuuteen. Jos Suomi haluaa vaikuttaa yhä vahvemmin EU-lainsäätämiseen, Suomelle tärkeät hankkeet pitäisi tunnistaa jo varhaisessa vaiheessa ja priorisoida selkeästi niiden hoitamista ministeriöissä.

Exploring business models for medical games: Key components and challenges

The costs of health care are going up in many countries. In order to provide affordable and effective health care solutions, new technologies and approaches are constantly being developed. In this research, video games are presented as a possible solution to the problem. Video games are fun, and nowadays most people like to spend time on them. In addition, recent studies have pointed out that video games can have notable health benefits. Health games have already been developed, used in practice, and researched. However, the bulk of health game studies have been concerned with the design or the effectiveness of the games; no actual business studies have been conducted on the subject, even though health games often lack commercial success despite their health benefits. This thesis seeks to fill this gap. The specific aim of this thesis is to develop a conceptual business model framework and empirically use it in explorative medical game business model research. In the first stage of this research, a literature review was conducted and the existing literature analyzed and synthesized into a conceptual business model framework consisting of six dimensions. The motivation behind the synthesis is the ongoing ambiguity around the business model concept. In the second stage, 22 semi-structured interviews were conducted with different professionals within the value network for medical games. The business model framework was present in all stages of the empirical research: First, in the data collection stage, the framework acted as a guiding instrument, focusing the interview process. Then, the interviews were coded and analyzed using the framework as a structure. The results were then reported following the structure of the framework. In the results, the interviewees highlighted several important considerations and issues for medical games concerning the six dimensions of the business model framework. Based on the key findings of this research, several key components of business models for medical games were identified and illustrated in a single figure. Furthermore, five notable challenges for business models for medical games were presented, and possible solutions for the challenges were postulated. Theoretically, these findings provide pioneering information on the untouched subject of business models for medical games. Moreover, the conceptual business model framework and its use in the novel context of medical games provide a contribution to the business model literature. Regarding practice, this thesis further accentuates that medical games can offer notable benefits to several stakeholder groups and offers advice to companies seeking to commercialize these games.

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.

University students’ regulation of learning and text processing – examples from medical and teacher education

The general aim of the thesis was to study university students’ learning from the perspective of regulation of learning and text processing. The data were collected from the two academic disciplines of medical and teacher education, which share the features of highly scheduled study, a multidisciplinary character, a complex relationship between theory and practice and a professional nature. Contemporary information society poses new challenges for learning, as it is not possible to learn all the information needed in a profession during a study programme. Therefore, it is increasingly important to learn how to think and learn independently, how to recognise gaps in and update one’s knowledge and how to deal with the huge amount of constantly changing information. In other words, it is critical to regulate one’s learning and to process text effectively. The thesis comprises five sub-studies that employed cross-sectional, longitudinal and experimental designs and multiple methods, from surveys to eye tracking. Study I examined the connections between students’ study orientations and the ways they regulate their learning. In total, 410 second-, fourth- and sixth-year medical students from two Finnish medical schools participated in the study by completing a questionnaire measuring both general study orientations and regulation strategies. The students were generally deeply oriented towards their studies. However, they regulated their studying externally. Several interesting and theoretically reasonable connections between the variables were found. For instance, self-regulation was positively correlated with deep orientation and achievement orientation and was negatively correlated with non-commitment. However, external regulation was likewise positively correlated with deep orientation and achievement orientation but also with surface orientation and systematic orientation. It is argued that external regulation might function as an effective coping strategy in the cognitively loaded medical curriculum. Study II focused on medical students’ regulation of learning and their conceptions of the learning environment in an innovative medical course where traditional lectures were combined wth problem-based learning (PBL) group work. First-year medical and dental students (N = 153) completed a questionnaire assessing their regulation strategies of learning and views about the PBL group work. The results indicated that external regulation and self-regulation of the learning content were the most typical regulation strategies among the participants. In line with previous studies, self-regulation wasconnected with study success. Strictly organised PBL sessions were not considered as useful as lectures, although the students’ views of the teacher/tutor and the group were mainly positive. Therefore, developers of teaching methods are challenged to think of new solutions that facilitate reflection of one’s learning and that improve the development of self-regulation. In Study III, a person-centred approach to studying regulation strategies was employed, in contrast to the traditional variable-centred approach used in Study I and Study II. The aim of Study III was to identify different regulation strategy profiles among medical students (N = 162) across time and to examine to what extent these profiles predict study success in preclinical studies. Four regulation strategy profiles were identified, and connections with study success were found. Students with the lowest self-regulation and with an increasing lack of regulation performed worse than the other groups. As the person-centred approach enables us to individualise students with diverse regulation patterns, it could be used in supporting student learning and in facilitating the early diagnosis of learning difficulties. In Study IV, 91 student teachers participated in a pre-test/post-test design where they answered open-ended questions about a complex science concept both before and after reading either a traditional, expository science text or a refutational text that prompted the reader to change his/her beliefs according to scientific beliefs about the phenomenon. The student teachers completed a questionnaire concerning their regulation and processing strategies. The results showed that the students’ understanding improved after text reading intervention and that refutational text promoted understanding better than the traditional text. Additionally, regulation and processing strategies were found to be connected with understanding the science phenomenon. A weak trend showed that weaker learners would benefit more from the refutational text. It seems that learners with effective learning strategies are able to pick out the relevant content regardless of the text type, whereas weaker learners might benefit from refutational parts that contrast the most typical misconceptions with scientific views. The purpose of Study V was to use eye tracking to determine how third-year medical studets (n = 39) and internal medicine residents (n = 13) read and solve patient case texts. The results revealed differences between medical students and residents in processing patient case texts; compared to the students, the residents were more accurate in their diagnoses and processed the texts significantly faster and with a lower number of fixations. Different reading patterns were also found. The observed differences between medical students and residents in processing patient case texts could be used in medical education to model expert reasoning and to teach how a good medical text should be constructed. The main findings of the thesis indicate that even among very selected student populations, such as high-achieving medical students or student teachers, there seems to be a lot of variation in regulation strategies of learning and text processing. As these learning strategies are related to successful studying, students enter educational programmes with rather different chances of managing and achieving success. Further, the ways of engaging in learning seldom centre on a single strategy or approach; rather, students seem to combine several strategies to a certain degree. Sometimes, it can be a matter of perspective of which way of learning can be considered best; therefore, the reality of studying in higher education is often more complicated than the simplistic view of self-regulation as a good quality and external regulation as a harmful quality. The beginning of university studies may be stressful for many, as the gap between high school and university studies is huge and those strategies that were adequate during high school might not work as well in higher education. Therefore, it is important to map students’ learning strategies and to encourage them to engage in using high-quality learning strategies from the beginning. Instead of separate courses on learning skills, the integration of these skills into course contents should be considered. Furthermore, learning complex scientific phenomena could be facilitated by paying attention to high-quality learning materials and texts and other support from the learning environment also in the university. Eye tracking seems to have great potential in evaluating performance and growing diagnostic expertise in text processing, although more research using texts as stimulus is needed. Both medical and teacher education programmes and the professions themselves are challenging in terms of their multidisciplinary nature and increasing amounts of information and therefore require good lifelong learning skills during the study period and later in work life.

Exploring Relationship between Pakistani Teachers’ Pedagogical Beliefs and ICT Use for Teaching and Learning

Background: The aim of present study is to investigate relationship between Pakistani teachers’ pedagogical beliefs and ICT use for teaching and learning. Previous studies found close relationship between pedagogical beliefs and teaching practices including use of ICT. However, variation in results is also reported and attributed to cultural and contextual differences. Methodology: Quantitative approach was used to study a sample of 231 Pakistani basic education teachers from middle and upper-middle range private schools, mostly from large urban centres. Results: This study confirmed previously study results that constructivist-compatible pedagogical beliefs are significantly related to both traditional and constructivist use of ICT. However, it is also found that traditional-transmission pedagogical beliefs are significantly related to traditional use of ICT – a finding not reported in previous studies. Some amounts of ICT training for pedagogical purpose exhibit significant impact on ICT use, in particular constructivist use of ICT. Similarly age also play a role as younger teachers are more likely to use ICT, however, no significant difference of pedagogical beliefs and ICT use was found between male and female teachers. Recommendation for practice and further investigation are made in chapter 5.

Exploring the use of prediction and summarization to increase students' listening and reading comprehension /

This study examined the effect of expHcitly instructing students to use a repertoire of reading comprehension strategies. Specifically, this study examined whether providing students with a "predictive story-frame" which combined the use of prediction and summarization strategies improved their reading comprehension relative to providing students with generic instruction on prediction and summarization. Results were examined in terms of instructional condition and reading ability. Students from 2 grade 4 classes participated in this study. The reading component of the Canadian Achievement Tests, Second Edition (CAT/2) was used to identify students as either "average or above average" or "below average" readers. Students received either strategic predication and summarization instruction (story-frame) or generic prediction and summarization instruction (notepad). Students were provided with new but comparable stories for each session. For both groups, the researcher modelled the strategic tools and provided guided practice, independent practice, and independent reading sessions. Comprehension was measured with an immediate and 1-week delayed comprehension test for each of the 4 stories, hi addition, students participated in a 1- week delayed interview, where they were asked to retell the story and to answer questions about the central elements (character, setting, problem, solution, beginning, middle, and ending events) of each story. There were significant differences, with medium to large effect sizes, in comprehension and recall scores as a fimction of both instructional condition and reading ability. Students in the story-frame condition outperformed students in the notepad condition, and average to above average readers performed better than below average readers. Students in the story-frame condition outperformed students in the notepad condition on the comprehension tests and on the oral retellings when teacher modelling and guidance were present. In the cued recall sessions, students in the story-frame instructional condition recalled more correct information and generated fewer errors than students in the notepad condition. Average to above average readers performed better than below average readers across comprehension and retelling measures. The majority of students in both instructional conditions reported that they would use their strategic tool again.

The exercise leader's gender and physique salience : effects on self-presentational concerns in an exercise context

Self-presentation is the process by which individuals attempt to monitor and control how others perceive and evaluate them (Leary, 1992; Leary & Kowalski, 1990). Self-presentational concerns have been shown to influence a number of exercise-related behaviours, cognitions, and affective responses to exercise (e.g., social anxiety). Social anxiety occurs when an individual wants to create a specific impression on others, but is unsure (s)he will be successful (Leary & Kowalski, 1995). Social physique anxiety (SPA) is a specific form of social anxiety related the evaluation of one's body (Hart, Leary, & Rejeski, 1989). Both social anxiety and SPA may act as deterrents to exercise (Lantz, Hardy, & Ainsworth, 1997; Leary, 1992), so it is important to examine factors that may influence social anxiety and SPA; one such factor is self-presentational efficacy (SPE). SPE is one's confidence in successfully making desired impressions on others (Leary & Atherton, 1986) and has been associated with social anxiety and SPA (Leary & Kowalski, 1995; Gammage, Martin Ginis, & Hall, 2004). Several aspects of the exercise environment, such as the presence of mirrors, clothing, and the exercise leader or other participant characteristics, may be manipulated to influence self-presentational concerns (e.g., Gammage, Martin Ginis et aI., 2004; Martin & Fox, 2001; Martin Ginis, Prapavessis, & Haase, 2005). Given that the exercise leader has been recognized as one of the most important influences in the group exercise context (Franklin, 1988), it is important to further examine how the leader may impact self-presentational concerns. The present study examined the impact of the exercise leader's gender and physique salience (i.e., the extent to which the body was emphasized) on SPE, state social anxiety (SSA), and state social physique anxiety (SPA-S) of women in a live exercise class. Eighty-seven college-aged female non- or infrequent exercisers (i.e., exercised 2 or fewer times per week) participated in a group exercise class led by one of four leaders: a female whose physique was salient; a female whose physique was non-salient; a male whose physique was salient; or a male whose physique was non-salient. Participants completed measures of SPE, SSA, and SPA-S prior to and following completion of a 30- minute group exercise class. In addition, a measure of social comparison to the exercise leader and other participants with respect to attractiveness, skill, and fitness was completed by participants following the exercise class. A MANOV A was conducted to examine differences between groups on postexercise variables. Results indicated that there were no significant differences between groups on measures ofSPE, SSA, or SPA-S (allp's > .05). However, when all participants were collapsed into one group, a MANOV A showed a significant time effect (F(3, 81) = 19.45,p < .05, 1')2= .419). Follow-up ANOVAs indicated that post-exercise SPE increased significantly, while SSA and SPA-S decreased significantly (SPE: F(I, 83) = 30.87,p < .001,1')2 = .27; SSA: F(I,83) = 11.09,p < .001, 1')2 = .12; SPA-S: F (1,83) = 42.79,p < .001, 1')2 = .34). Further, results of a MANOVA revealed that participants who believed they were less fit than other group members (i.e., made negative social comparisons) reported significantly more post-exercise SSA and SP A-S than those who believed they were more fit than the other participants (i.e., made positive comparisons; SSA: F(2, 84) = 3.46, p < .05, 1')2 = .08; SPA-S: F(2, 84) = 5.69, p < .05, 1')2 = .12). These results may indicate that successfully completing an exercise class may serve as a source of SPE and lead to reduced social anxiety and SPA-S in this population. Alternatively, characteristics of the exercise leader may be less important than characteristics of the other participants. These results also suggest that the types of social comparisons made may influence self-presentational concerns in this sample. Future research should examine how the type of social comparison (i.e., negative or positive) made to the other group members may either generate or reduce anxiety. Also, factors that contribute to the types of social comparisons made with other exercisers should be examined. Implications for practice and research are discussed.
