Terveyteen liittyvä elämänlaatu laitoskuntoutuksen vaikuttavuuden arvioinnissa : RAND-36-mittarin soveltuvuus työikäisten laitoskuntoutuksen ongelmaprofiilin määrittämiseen ja kuntoutuksen vaikutusten arvioimiseen

The aim of the present research was to examine the validity of the RAND-36 measure of health-related quality of life among the working age rehabilitation clients. The research included two cross-sectional studies and one follow-up study. The subjects of the first study (n = 794) participated in the first period of the five following types of rehabilitation: occupationally oriented medical rehabilitation, musculoskeletal rehabilitation, medical rehabilitation for job burnout, rehabilitation for supporting the work ability and capacity of disabled subjects (vocational rehabilitation) and individualized rehabilitation between October 2000 and October 2001. The subjects of the second study (n = 990) participated in the same rehabilitation during their first rehabilitation period between May 2007 and May 2008. The first subjects participated in a follow-up period no later than May 2003 with the exception of the individual rehabilitation clients (n = 588). Based on the ICF classification, the RAND-36 provides a diverse measure of the health-related quality of life and of the capacity for subjective, perceived physical and psycho-social functioning. The construct properties of the RAND-36 measure proved to be very consistent on the basis of both the cluster and confirmatory factor analyses. At the group level, the RAND-36 measure was shown to be illustrative and sensitive in differentiating the clients’ rehabilitation needs. The results of cluster analyses with the two cross-sectional data indicated a consistent five-cluster solution of rehabilitation groups on the basis of the eight subscales of health-related quality of life. Each of these clusters represented a clear difference in their need for rehabilitation. The RAND-36 measure proved to be sensitive to change. The changes observed in the pre- and post-conditions in relation to all the subscales of quality of life were statistically significant. Depending on the rehabilitation type, different changes in the subscales of the measure were observed, and these changes corresponded to the different emphasis and goals of the specific type of rehabilitation intervention. Similarly, changes in the subscales of the measure were observed in relation to the RAND groups formed by cluster analysis, which were logical and corresponded to the problem profiles of these groups. The confirmatory factor analysis indicated a two-factor solution: an index of the capacity for physical functioning (self-rated general health, bodily pain, physical functioning, physical role functioning) and an index of the capacity for psycho-social functioning (psychological well-being, social functioning, psychological role functioning and energy). These two indices describing functional capacity proved also to be sensitive to change. This two-factor solution seems to be usable for group level analyses when assessing the effects of rehabilitation. The moderately strong correlation between the RAND-36 and work ability index suggests that they partly measure the same phenomenon: perceived health-related quality of life, subjective capacity for activity and perceived work ability have strong links. As expected, the capacity for physical functioning had a stronger correlation with work ability index than with the capacity for psycho-social functioning. According to the present research, the RAND-36 measure can be considered as a screening method for rehabilitation orientation in relation to rehabilitation needs and as a follow-up measure for the health-related quality of life among the working age clients. The RAND-36 measure is also shown to be a useful instrument in estimating the benefits of rehabilitation as well as in effectiveness research.

Molecular methods for the epidemiological analysis of methicillin-resistant Staphylococcus aureus (MRSA) and Streptococcus pneumoniae

Methicillin-resistant Staphylococcus aureus (MRSA) and Streptococcus pneumoniae are major health problems worldwide, both found in symptomless carriage but also causing even life-threatening infections. The aim of this thesis was to characterise MRSA and S. pneumoniae in detail by using several molecular typing methods for various epidemiological purposes: clonality analysis, epidemiological surveillance, outbreak investigation, and virulence factor analysis. The characteristics of MRSA isolates from the strain collection of the Finnish National Infectious Disease Register (NIDR) and pneumococcal isolates collected from military recruits and children with acute otitis media (AOM) were analysed using various typing techniques. Antimicrobial susceptibility testing, pulsed-field gel electrophoresis (PFGE), multilocus sequence typing (MLST), spa typing, staphylococcal cassette chromosome mec (SCCmec) typing, and the detection of Panton-Valentine leukocidin (PVL) genes were performed for MRSA isolates. Pneumococcal isolates were analysed using antimicrobial susceptibility testing, serotyping, MLST, and by detecting pilus islet 1 (PI-1) and 2 (PI-2) genes. Several international community- and hospital-associated MRSA clones were recognised in Finland. The genetic diversity among MRSA FIN-4 isolates and among FIN-16 isolates was low. Overall, MRSA blood isolates from 1997 to 2006 were genetically diverse. spa typing was found to be a highly discriminatory, rapid and accurate typing method and it also qualifies as the primary typing method in countries with a long history of PFGE-based MRSA strain nomenclature. However, additional typing by another method, e.g. PFGE, is needed in certain situations to be able to provide adequate discrimination for epidemiological surveillance and outbreak investigation. An outbreak of pneumonia was associated with one pneumococcal strain among military recruits, previously healthy young men living in a crowded setting. The pneumococcal carriage rate after the outbreak was found to be exceptionally high. PI-1 genes were detected at a rather low prevalence among pneumococcal isolates from children with AOM. However, the study demonstrated that PI-1 has existed among pneumococcal isolates prior to pneumococcal conjugate vaccine and the increased antimicrobial resistance era. Moreover, PI-1 was found to associate with the serotype rather than the genotype. This study adds to our understanding of the molecular epidemiology of MRSA strains in Finland and the importance of an appropriate genotyping method to be able to perform high-level laboratory-based surveillance of MRSA. Epidemiological and molecular analyses of S. pneumoniae add to our knowledge of the characteristics of pneumococcal strains in Finland.

Factors related to seat belt use : A Turkish case

Seat belts are effective safety devices used to protect car occupants from severe injuries and fatalities during road vehicle accidents. Despite the proven effectiveness of seat belts, seat belt use rates are quite low, especially in developing countries, such as Turkey. The general aim of the present study was to investigate a large variety of factors related to seat belt use among Turkish car occupants using different perspectives and methods and therefore, to contribute to the design of effective seat belt use interventions for increasing seat belt use rates in Turkey. Five sub-studies were conducted within the present study. In the first sub-study, environmental (e.g., road type) and psycho-social factors (e.g., belt use by other car occupants) related to the seat belt use of front-seat occupants were investigated using observation techniques. Being male, of a young age, and traveling on city roads were the main factors negatively related to seat belt use. Furthermore, seat belt use by the drivers and front-seat passengers was highly correlated and a significant predictors of each other. In the second sub-study, the motivations of the car occupants for seat belt use and non-use were investigated using interview techniques. Situational conditions, such as traveling on city roads and for short distances, and not believing in the effectiveness and relevance of seat belt use for safety, were the most frequently reported reasons for not using a seat belt. Safety, habit and avoiding punishment were among the most frequently reported reasons for using a seat belt. In the third sub-study, the Theory of Planned Behavior (TPB) and the Health Belief Model (HBM) were applied to seat belt use using Structural Equation Modeling techniques. The TPB model showed a good fit to the data, whereas the HBM showed a poor fit to the data. Within the TPB model, attitude and subjective norm were significant predictors of intentions to use a seat belt on both urban and rural roads. In the fourth sub-study, seat belt use frequency and motivations for seat belt use among taxi drivers were investigated and compared between free-time and work-time driving using a survey. The results showed that taxi drivers used seat belts more when driving a private car in their free-times compared to when driving a taxi during their work-times. The lack of a legal obligation to use a seat belt in city traffic and fear of being attacked or robbed by the passengers were found as two specific reasons for not using a seat belt when driving a taxi. Lastly, in the fifth sub-study, the relationship of seat belt use to driver and health behaviors was investigated using a survey. Although seat belt use was related both to health and driver behaviors, factor analysis results showed that it grouped with driver behaviors. Based on the results of the sub-studies, a tentative empirical model showing different predictors of seat belt use was proposed. According to the model, safety and normative motivations and perceived physical barriers related to seat belt use are the three important predictors of seat belt use. Keywords: Seat belt use; environmental factors; psycho-social factors; safety and normative motivations; the Theory of Planned Behavior; the Health Belief Model; health behaviors; driver behaviors; front-seat occupants; taxi drivers; Turkey.

Esimiestaitojen tärkeys, hallinta ja kehitystarpeet

This study examines the leadership skills in municipal organisation. The study reflects the manager views on leadership skills required. The purpose of this study was to reflect the most important leadership skills currently and in the future as well as the control of these skills. The study also examines the importance of the change and development needs of the leadership skills. In addition, the effect of background variables on evaluation of leadership skills were also examined. The quantitative research method was used in the study. The material was collected with the structured questionnaire from 324 Kotka city managers. SPSS-program was used to analyse the study material. Factor analysis was used as the main method for analysis. In addition, mean and standard deviations were used to better reflect the study results. Based on the study results, the most important leadership skills currently and in the future are associated with internet skills, work control, problem solving and human resource management skills. Managers expected the importance of leadership skills to grow in the future. Main growth is associated with the software utilisation, language skills, communication skills as well as financial leadership skills. Strongest competence according to managers is associated with the internet skills. Managers also considered to control well the skills related to employee know-how and manager networking. In addition, significant development needs are required in leadership skills. Main improvement areas were discovered in software utilisation, work control, human resource management skills as well as skills requiring problem solving. It should be noted that the main improvement areas appeared in the leadership skills that were evaluated as most important apart from software utilisation. Position, municipal segments and sex were observed to explain most of the deviation in received responses.

Mikä yliopisto-opiskelijaa kiihdyttää? : Opiskeluympäristöjen tutkimusta CASS-kokemusotantamenetelmällä flow-teoriaa ja ydintunneteorioita soveltaen

Flow experience is often defined either as an experience of high concentration and enjoyment or as a situation, where high challenges are matched with high skills. According to core-emotion theories, the experience of any emotion contains two core emotions: valence and arousal. Through an accurate mathematical model, the present study investigated, whether the experience of concentration and enjoyment is related to situations where both challenge and skills are high and in balance. Further, it was investigated what sort of core emotions are related to differing relationships between challenge and skills. Finally, university students’ experiences of their natural study environments were described in terms of core emotions and in terms of relationships between challenge and skills. Participants were 55 university students who participated two weeks research period. Altogether 3367 questionnaire answers were collected with the CASS experience-sampling method, operating in 3G-mobile phones. The relationship between challenge and skills (competence) was defined in an exact way in polar coordinates. An enjoyable and concentrated flow experience was defined as a sum variable of absorption, interest and enthusiasm. Core emotions were calculated with factor analysis from nine emotion variables. As expected, an experience of concentration and enjoyment was, on average, related to the situations where both challenge and skills were high and in balance. This was not, however, the case in every situation. Thus, it should be taken into consideration how flow experience is operationalised in experience sampling studies. When flow experience was defined as a situation of high challenge and high skills, it was often related to high valence and arousal emotions such as excitement or enthusiasm. A happier or a more tranquil enjoyment was related to situations of moderate challenge and high skills. Experiences differed clearly between various natural study environments. At lectures students were often bored or mentally absent, and did not experience challenges. In a small group students were often excited or enthusiastic, and showed optimal balance between challenge and skills. At library students felt satisfied and were engaged in highly challenging work.

Ryhmäidentiteetin mittaaminen verkkoroolipelissä World of Warcraft

The objective of the study was to explore the dimensions of group identity in the guilds of World of Warcraft. Previous research shows that social interaction has an important role in playing games for many players. Social identities are an important aspect of self-concept and since group related cues are more salient than personal clues in computer-mediated communication, the social gaming experience was approached through group identity. In the study a new scale will be developed to measure the group identity in games. Secondary goal is to study how different guild attributes affect the group identity and third goal is to explore the connection between group identity and gaming experience and amount of play. Subjects were 1203 guild members and 106 players not in a guild. The data was gathered by an Internet survey which measured group identity with nine scales, gaming experience with three scales and guild attributes with four scales. Also various background data was gathered. The construct of group identity was analyzed with explorative factor analysis. The typical experiences of group identity was analyzed with cluster analysis and effects of guild attributes with multivariate analysis of covariance. As a result of the study a new scale was developed which measured group identity on six dimensions: self-stereotyping, public and private evaluation, importance, interconnection of self and others and awareness of content. Group identity was experienced strongest in elder middle-sized guilds that had formal rules and that emphasized social interaction. The players with strong group identity had more positive gaming experience and played World of Warcraft more per week than the players who were not in a guild or identified to guild weakly. This result encourages game developers to produce environments that enhance group identity as it seems to increase the enjoyment in games. As a whole this study proposes that group identity in guilds is constructed from the same elements as in traditional groups. If this is truly the case, guild membership may have similar positive effects on individual’s mental well-being as traditional positively evaluated group memberships have.

Sense of Community in Web Environment

The study of social phenomena in the World Wide Web has been rather fragmentary, andthere is no coherent, reseach-based theory about sense of community in Web environment. Sense of community means part of one's self-concept that has to do with perceiving oneself belonging to, and feeling affinity to a certain social grouping. The present study aimed to find evidence for sense of community in Web environment, and specifically find out what the most critical psychological factors of sense of community would be. Based on known characteristics of real life communities and sense of community, and few occational studies of Web-communities, it was hypothesized that the following factors would be the most critical ones and that they could be grouped as prerequisites, facilitators and consequences of sense of community: awareness and social presence (prerequisites), criteria for membership and borders, common purpose, social interaction and reciprocity, norms and conformity, common history (facilitators), trust and accountability (consequences). In addition to critical factors, the present study aimed to find out if this kind of grouping would be valid. Furthermore, the effect of Web-community members' background variables to sense of community was of interest. In order to answer the questions, an online-questionnaire was created and tested. It included propositions that reflect factors that precede, facilitate and follow the sense of community in Web environment. A factor analysis was calculated to find out the critical factors and analyses of variance were calculated to see if the grouping to prerequisites, facilitators and consequences was right and how the background variables would affect the sense of community in Web environment. The results indicated that the psychological structure of sense of community in Web environment could not be presented with critical variables grouped as prerequisites, facilitators and consequences. Most factors did facilitate the sense of community, but based on this data it could not be argued that some of the factors chronologically precedesense of community and some follow it. Instead, the factor analysis revealed that the most critical factors in sense of community in Web environment are 1) reciprocal involvement, 2) basic trust for others, 3) similarity and common purpose of members, and 4) shared history of members. The most influencing background variables were the member's own participation activity (indicated with reading and writing messages) and the phase in membership lifecycle (from visitor to leader). The more the member participated and the further in membership life cycle he was, the more he felt sense of community. There are many descreptions of sense of community, but the present study was one of the first to actually measure the phenomenon in Web environment, and that gained well documented, valid results based on large data, proving that sense of community in Web environment is possible, and clarifying its psychological structure, thus enhancing the understanding of sense of community in Web environment. Keywords: sense of community, Web-community, psychology of the Internet

"Pintaa syvemmälle" : Eettinen pohdinta opettajan voimavarana luokanopettajan ja erityisopettajan silmin

The purpose of this study is to determine what class teachers and special teachers emphasise in ethical consideration, in which situations they find that ethical difficulties arise and how they would overcome them. In additions, the study aims to describe the effects of ethical con-sideration on the teachers` work. The theoretical backround is based on theories concerning the ethics of the teacher and the literature associated with education and teaching. The empirical study was based on data obtained through questionnaires and interviews. The questionnaires were posted to 470 randomly-selected class teachers and special teachers; 298 of them (63%) completed and returned the questionnaire, and 19 teachers were inter-viewed. The results of the questionnaires and the interviews were examined crosswise with a mixed-methods procedure. The questionnaires were analysed by factor analysis. Those items which rose above the av-erage served as the foundation for the analysis. The questionnaires also included open ques-tions. These questions and the interviews were analysed with a content analysis method. Some principles of this method were combined with the results of the questionnaires to in-crease mutual understanding. In this study, the ethical consideration of the teachers was divided in to four notable parts: 1) moral obligations, 2) respect for the teaching stuff, 3) the demand for responsibility, and 4) dependence on the situation. These items were also notable both in situations that were ethi-cally difficult for teachers and in their solutions to these situations. It became evident that these situations were very common in everyday work and resulted from the character of the teachers´ work. This study showed that the teacher meets the pupils as a group and that the teacher must examine according to the circumstances the truth, individuality, special ar-rangements and co-operation between the school and the parents. The teachers` continuous lack of time limited the ethical consideration. It emerged that the teachers consider their work very multi-faceted and that the sense of obligation, power and responsibility was inevitably received emphasis. The consciousness of authority and the responsibilities associated with it seemed, however, to strengthen this ac-tion. The study showed that the teachers, especially the young female ones, long for more solidarity. Significantly, such experience does not eliminate the importance of ethical consid-eration; on the contrary, it deepens it. According to the results, creating conditions and cir-cumstances for the teachers that open co-operation is inevitable, and easy interaction will in-evitably be possible in the future. There was not observed any differences in ethical consideration between class teachers and special teachers. Therefore, the integration of the pupils to general teaching cannot be consid-ered questionable. Teachers´ answers suggested that ethical consideration improved the tolerance of stress, increased self-confidence and courage as well as belief in the future. The teachers considered ethical consideration important and encouraging for it increased justice and empathy in the teachers´ work.

Nuorten arvot ja tietoyhteiskunta-asenteet

The aim of this study was to explore the sociocultural value orientations of Finnish adolescents and their attitudes toward information society. In addition, this study explored the association between values and attitudes toward information society. I investigated whether values and attitudes follow social development and whether they can be divided into value categories such as traditional, modern and postmodern. This study falls into the category of youth research. The study uses a multimethodological approach and straddles the following disciplines: the science of education, religious education, sociology and social psychology. The theoretical context of the study is modernisation, understood as a two level process. The first level represents the transition from a religious-based traditional society to a modern industrial society. The second level of modernisation refers to the process of development established after the second world war, called postmodernisation, which is understood as the transition from an emphasis on economical imperatives to an emphasis on subjective well-being and the quality of life. Postmodernisation influences both social organisations and individuals´ values and worldviews. The target group of this survey-study comprised 408 16- to 19-year-old Finnish adolescent students from secondary school and vocational school. The data were gathered with a quantitative questionnaire during the second half of 2001. The results of the study can be generalised to the population of Finnish 16- to 19-year-olds. The data were analysed quantitatively using ANOVA and multivariate analyses such as cluster analysis, factor analysis and general linear modeling. Bayesian dependence modeling served to explore further how the values predict the attitudes toward information society. The results indicate that values are associated not only with attitudes toward information society, but with many other sociocultural indicator as well. Especially strong interpreting indicators included gender and identity or lifestyle questions. The results also indicate an association between values, attitudes and social development and a two-level modernisation process. Values formed traditional, modern and postmodern value systems. Keywords: values, attitudes, modernisation, information society, traditional, modern, postmodern

Större frihet - bättre lokalt anpassad service? : Förvaltningsreformer och kommunernas service för utvecklingsstörda 1994-2000

In the beginning of the 1990s the legislation regarding the municipalities and the system of central government transfers were reformed in Finland. This resulted in a move from detailed governmental control to increased municipal autonomy. The purpose of this decentralization was to enable the municipalities to better adapt their administration and service supply to local needs. The aim of this study was to explore the effects of the increased municipal autonomy on the organization of services for people with intellectual disabilities. Did the increased autonomy cause the municipalities to alter their service supply and production and did the services become more adapted to local needs? The data consists of statistical information on service use and production, and also of background data such as demographics, economics and political elections on 452 municipalities in Finland from the years 1994 and 2000. The methods used are cluster analysis, discriminant analysis and factor analysis. The municipalities could be grouped in two categories: those which offered mainly one kind of residential services and others which had more varied mixes of services. The use of institutional care had decreased and municipalities which used institutional care as their primary form of service were mostly very small municipalities in 2000. The situation had changed from 1994, when institutional care was the primary service for municipalities of all sizes. Also the service production had become more differentiated and the municipalities had started using more varied ways of production. More municipalities had started producing their own services and private production had increased as well. Furthermore, the increase in local autonomy had opened up possibilities for local politics to influence both the service selection and methods of production. The most significant motive for changes in the service structure was high unemployment and an increasing share of elderly people in the population, particularly in sparsely populated areas. Municipalities with a low level of resources had made more changes in their service organization while those with more resources had been able to carry on as before. Key words: service structure, service for people with intellectual disabilities, municipalities, contingency theory, New Public Management

Muuttoliike ja vetovoimatekijät Helsingissä : - Kyselyaineiston analyysi

This thesis explores migration and the attractiveness of urban living in the Greater Helsinki region. The aim of the thesis is to explore the attractiveness of the city of Helsinki in terms of regional migration and to identify what characterizes migration to Helsinki. The study focuses in particular on housing, which is a key factor influencing migration decisions in the region. Other central themes in the study are housing policy and regional competition among municipalities. This study focuses solely on households moving within Finnish borders excluding international migration. Migration is examined by comparing in- and out-migration in Helsinki, as well as studying migration to the city s inner and outer areas. The primary research material in the study is a questionnaire data collected by the National Consumer Research Centre. In this thesis the data is used for studying migrants aged 25 45. The main research method is analyzing the data statistically using the SPSS software. Methods include frequency analysis, cross tabulation, factor analysis and descriptive analysis. Additionally, statistical data is used to complement the questionnaire data. The research results indicate that Helsinki s in- and out-migration differs both in terms of the type of households that migrate as well as in the reasons why they migrate. Furthermore, differences can also be detected between migration to the inner and outer parts of Helsinki. According to the research results, a household s current phase of life is crucial in determining where and why they move within the Greater Helsinki region. A household s set of values on the other hand, seems to have a lesser impact on migration within the region, even though households moving to Helsinki seem to value a somewhat more urban lifestyle than the ones moving out of the city. The research also shows a direct correlation between the values of migrants and their current phase of life. Decisions of migrating are heavily influenced by wider societal issues. In the Greater Helsinki region the labor and housing market appear to have a great influence on the direction of migration streams. According to the results, households move to and from Helsinki for different reasons. The primary reasons for moving to Helsinki are related to the city s diverse labor market and to the working careers of households. Issues related to urban living and an urban lifestyle seem to be relevant although not the main reason why people move to Helsinki. The research material indicates that Helsinki s urban environment is both a pull and a push factor affecting the decisions of migrants. The city attracts those seeking urban living, but on the contrary does not appeal to households seeking more space and wishing to live closer to nature. According to the research, Helsinki with its densely built urban environment mainly attracts singles and childless couples, whereas the city region s other municipalities are more attractive for families with children. Housing policy is one of the main reasons determining where people move within the Helsinki region. As for the city of Helsinki, improving the city s attractiveness seems to be closely linked to how well the city manages to execute its future housing policies and how well alternative living preferences can be taken into account in planning.

Ammatillisten opettajien tieto- ja viestintätekniikan opetuskäytön intentionaalisuutta selittävät tekijät

Intention-based models have been one of the main theoretical orientations in the research on the implementation of information and communication technology (ICT). According to these models, actual behavior can be predicted from the intention towards the behavior. If the level of intention to use technology is high, the probability of actual usage of ICT increases. The purpose of this study was to find out which factors explain vocational teachers intention to use ICT in their teaching. In addition, teachers of media and information sciences and teachers of welfare and health were compared. The study also explored how regularly ICT was applied by teachers and how strong their intention to apply the technology was. This Master s thesis is a quantitative study and the data was collected using an Email survey and Eform. The instruments were based on a decomposed theory of planned behavior. The research group consisted of 22 schools of media and information sciences and 20 schools of welfare and health. The data consisted of 231 vocational teachers: 57 teachers worked with media and information sciences and 174 with welfare and health. The data was analyzed using Mann-Whitney U-test, factor analysis and regression analysis. In addition, categorized results were compared with previous study. In this study, the intention to use ICT in teaching was explained by the teachers attitudes and skills and the attitudes of their work community. However, the environment in which ICT was used, i.e., the technical environment, economical resources and time, did not explain the intention. The results did not directly support any of the intention-based models, but they could be interpreted as congruent with the technology acceptance model. The majority of the teachers used ICT at least weekly. They had a strong intention to continue to do that in the future. The study also revealed that there were more teachers who had a critical attitude towards ICT among the teachers of welfare and health. According to the results of this study, it is not possible to state that ICT would not suit any one profession because in every group with teachers with a critical attitude towards ICT there were also teachers with a positive attitude.

Sustainability and Mission Drift in Microfinance

Microfinance institutions (MFIs) are constrained by double bottom-lines: meeting social obligations (the first bottom-line) and obtaining financial self-sufficiency (the second bottom-line). The proponents of the first bottom-line, however, are increasingly concerned that there is a trade-off between these two bottom-lines—i.e., getting hold of financial self-sufficiency may lead MFIs to drift away from their original social mission of serving the very poor, commonly known as mission drift in microfinance which is still a controversial issue. This study aims at addressing the concerns for mission drift in microfinance in a performance analysis framework. Chapter 1 deals with theoretical background, motivation and objectives of the topic. Then the study explores the validity of three major and related present-day concerns. Chapter 2 explores the impact of profitability on outreach-quality in MFIs, commonly known as mission drift, using a unique panel database that contains 4-9 years’ observations from 253 MFIs in 69 countries. Chapter 3 introduces factor analysis, a multivariate tool, in the process of analysing mission drift in microfinance and the exercise in this chapter demonstrates how the statistical tool of factor analysis can be utilised to examine this conjecture. In order to explore why some microfinance institutions (MFIs) perform better than others, Chapter 4 looks at factors which have an impact on several performance indicators of MFIs—profitability or sustainability, repayment status and cost indicators—based on quality-data on 353 institutions in 77 countries. The study also demonstrates whether such mission drift can be avoided while having self-sustainability. In Chapter 5 we examine the impact of capital and financing structure on the performance of microfinance institutions where estimations with instruments have been performed using a panel dataset of 782 MFIs in 92 countries for the period 2000-2007. Finally, Chapter 6 concludes the study by summarising the results from the previous chapters and suggesting some directions for future studies.

Inventory Routing - A Strategic Management Accounting Perspective

This dissertation develops a strategic management accounting perspective of inventory routing. The thesis studies the drivers of cost efficiency gains by identifying the role of the underlying cost structure, demand, information sharing, forecasting accuracy, service levels, vehicle fleet, planning horizon and other strategic factors as well as the interaction effects among these factors with respect to performance outcomes. The task is to enhance the knowledge of the strategic situations that favor the implementation of inventory routing systems, understanding cause-and-effect relationships, linkages and gaining a holistic view of the value proposition of inventory routing. The thesis applies an exploratory case study design, which is based on normative quantitative empirical research using optimization, simulation and factor analysis. Data and results are drawn from a real world application to cash supply chains. The first research paper shows that performance gains require a common cost component and cannot be explained by simple linear or affine cost structures. Inventory management and distribution decisions become separable in the absence of a set-dependent cost structure, and neither economies of scope nor coordination problems are present in this case. The second research paper analyzes whether information sharing improves the overall forecasting accuracy. Analysis suggests that the potential for information sharing is limited to coordination of replenishments and that central information do not yield more accurate forecasts based on joint forecasting. The third research paper develops a novel formulation of the stochastic inventory routing model that accounts for minimal service levels and forecasting accuracy. The developed model allows studying the interaction of minimal service levels and forecasting accuracy with the underlying cost structure in inventory routing. Interestingly, results show that the factors minimal service level and forecasting accuracy are not statistically significant, and subsequently not relevant for the strategic decision problem to introduce inventory routing, or in other words, to effectively internalize inventory management and distribution decisions at the supplier. Consequently the main contribution of this thesis is the result that cost benefits of inventory routing are derived from the joint decision model that accounts for the underlying set-dependent cost structure rather than the level of information sharing. This result suggests that the value of information sharing of demand and inventory data is likely to be overstated in prior literature. In other words, cost benefits of inventory routing are primarily determined by the cost structure (i.e. level of fixed costs and transportation costs) rather than the level of information sharing, joint forecasting, forecasting accuracy or service levels.

Late-industrial sawmill customers.

The methods of secondary wood processing are assumed to evolve over time and to affect the requirements set for the wood material and its suppliers. The study aimed at analysing the industrial operating modes applied by joinery and furniture manufacturers as sawnwood users. Industrial operating mode was defined as a pattern of important decisions and actions taken by a company which describes the company's level of adjustment in the late-industrial transition. A non-probabilistic sample of 127 companies was interviewed, including companies from Denmark, Germany, the Netherlands, and Finland. Fifty-two of the firms were furniture manufacturers and the other 75 were producing windows and doors. Variables related to business philosophy, production operations, and supplier choice criteria were measured and used as a basis for a customer typology; variables related to wood usage and perceived sawmill performance were measured to be used to profile the customer types. Factor analysis was used to determine the latent dimensions of industrial operating mode. Canonical correlations analysis was applied in developing the final base for classifying the observations. Non-hierarchical cluster analysis was employed to build a five-group typology of secondary wood processing firms; these ranged from traditional mass producers to late-industrial flexible manufacturers. There is a clear connection between the amount of late-industrial elements in a company and the share of special and customised sawnwood it uses. Those joinery or furniture manufacturers that are more late-industrial also are likely to use more component-type wood material and to appreciate customer-oriented technical precision. The results show that the change is towards the use of late-industrial sawnwood materials and late-industrial supplier relationships.
