This thesis consists of four empirical studies on women and men in European labour markets. Study I examines effects of the sex of the immediate supervisor on the time men and women spend in initial on-the-job training (OJT) in Sweden. The results show that men receive longer initial OJT than women do, but men’s time in training is independent of the supervisor’s sex. For women in the private sector, the chances of receiving long initial OJT are higher if the immediate supervisor is a man. Study II analyses effects of labour market institutions on the quality of part-time work by comparing the skills and autonomy of female part-time jobs in Britain and Sweden. The results show that female part-time employees in Sweden hold positions of higher skill and have more autonomy compared to their equivalents in Britain. Both British and Swedish part-time employees face relative disadvantages when compared to female full-time workers. Study III examines associations between maternal employment policies and wage penalties for mothers by skill in 10 European countries. The results indicate that, net of variation in female labour force participation, extensive publicly funded childcare is associated with a modest decrease in the motherhood wage penalty, regardless of skill. By contrast, paid maternity leave is weakly associated with a larger motherhood wage gap in less skilled jobs only. Study IV examines the extent to which women’s opportunities to attain positions of high workplace authority are related to maternal employment policies, such as paid parental leave and part-time work. Based on data from 25 European countries, the results show that a high proportion of women working long part-time hours is associated with a wider gender gap in the attainment of high authority positions, to the disadvantage of women. However, paid parental leave appears to be unrelated to the gender authority gap. / At the time of the doctoral defense, the following papers were unpublished and had a status as follows: Paper 1: Manuscript. Paper 2: In press. Paper 3: Manuscript. Paper 4: Manuscript.

This thesis consists of four constituent studies exploring several common themes: female participation in employment, normative assumptions regarding the proper roles of males and females, and social change. The underlying focus is gendered division of work, which is explored through the concept of family models. These models are conceptualized with reference to the interrelationships between female employment, availability of care services outside the family, and sharing of care work within the family. The empirical analysis is mostly based on the Baltic countries, but also includes Germany, Sweden, and Russia. By examining the variation between the countries, the research aims to highlight some common issues regarding the gendered division of work, issues that bridge the East/West divide. The data come from three sources: 1) available national descriptive statistics, 2) surveys, namely, the International Social Survey Programme (ISSP) ‘Family and Changing Gender Roles’ modules and the European Values Survey (EVS), and 3) nineteen problem-centred interviews with women who experienced hardships in the Lithuanian labour market. The analyzed time period starts with the collapse of socialism. The studies call into question the assumption that strong support for the traditional ‘male breadwinner/female carer’ family model in post-socialist societies contributed to the exclusion of women from the labour market. Comparing male and female employment indicators revealed no general pattern of female exclusion from the labour market. Moreover, gender-role attitudes are neither uniform nor traditional in the studied societies. The most valid generalization would be that there is a trend towards less traditional attitudes over time, more precisely, towards greater acceptance of women’s working roles. Summarizing the current situation regarding the gendered division of work, with reference to policies, practices, and attitudes, reveals the presence of ‘adult worker’ family models in Eastern Europe.

<p>The question as to which language should be used as a medium of instruction in schools in multilingual societies is a controversial one. In South Africa, the question is often posed in binary terms: Should the medium of instruction be a familiar local language such as Xhosa or a language of wider communication like English? This study is an attempt to answer the above question. The study profiled the writing abilities of Grade 4 and Grade 7 pupils at Themba Primary, a school located in Khayelitsha in the Western Cape, in both their mother tongue, Xhosa, and in English, their official medium of instruction at school since Grade 4. Three written tasks, which consisted of a narrative piece of writing, a reading comprehension exercise, and an expository piece of writing, were administered to the pupils in English and Xhosa. The purpose of the exercise was to examine some of the implications for educational language policy of the differences in performance in the two languages. All the tasks were authentic, in that they were based on aspects of the pupils&rsquo / curriculum and written in the formal academic language pupils were expected to be exposed to in their respective grades. All the tasks were graded systematically under controlled conditions.</p>

This doctoral thesis explores the agrarian development in 20th Estonia and the role of family farming during three major agricultural transformations. It consists of four papers and an introductory chapter for which the common departure are the situation appearing in the Estonian farming landscape after the regained independence in 1991. The first three studies analyse comparative aspects on Estonia's interwar experiences with focus on land reform, agricultural co-operation, and agricultural export development. The fourth study focuses on the role of private plots during the Soviet period and the conversion of these into subsistence holdings after 1991. By merging the perspectives in these papers, the introductory chapter explores the impacts and legacies of previous transformations on the post-Soviet agricultural transformation up to 2004. The thesis specifically analyses the long-term effects of perceptions of markets and the role of agricultural production, changes in the agrarian property relations, organisation of agricultural production and co-operation. In analytical terms, this is discussed from the perspectives of continuity and discontinuity. Besides the several societal changes affecting the agrarian property relations in 20th century Estonia, the radical and decisive shifts have also affected markets, trade and economic integration. Since the end of the First World War, Estonia has been quickly thrown between different economic-political systems and legal environments. From the perspective of the small state’s dependence on trade and reliance on a few markets, the upheavals in the early 1920s, after World War II, and not least the fall of the Soviet Union, Estonia’s long-term economic development has been significantly affected. In this context the role of agriculture has changed. Most important, however, this dissertation shows how the idea of small-scale family farming survived throughout the planned economic period and became an indispensable production unit, even though it turned out to be a myth as soon as the Soviet system was dissolved and the exposure to international competition began after 1991.

La valutazione dei docenti occupa un ruolo centrale nelle agende politiche dei governi; l’Italia ha avviato una riflessione in questa direzione ma ad oggi gli insegnanti non sono valutati. La ricerca analizza la relazione tra l’introduzione di un sistema di valutazione degli insegnanti e la promozione di comunità professionali nelle scuole; la valutazione dei docenti è considerata strumento utile allo sviluppo di una scuola come comunità professionale. Lo studio dei sistemi di valutazione degli insegnanti, pur non prescindendo da un’analisi economica, deve essere accompagnato da una visione pedagogica sulla scuola e sulla funzione docente, intendendosi sugli elementi che le fondano; la prospettiva di lavoro reputa la professionalità un prisma complesso costituito da dimensioni personali, organizzative e comunitarie. È stata indagata una realtà statunitense innovativa e sistematica per il modello impiegato per valutare gli insegnanti: Denver Professional Compensation System for Teachers, così da offrire spunti di riflessione anche per l’Italia. Dall’analisi sono emersi gli snodi e le opportunità della valutazione della professionalità docente: i vantaggi di una valutazione a servizio della pratica professionale, che prevede interventi alla carriera, alle retribuzioni, che integra forme e modalità differenti di valutare la professionalità e che è collegata al decision making. / The assessment of teachers plays a central role in the political agendas of governments; in Italy there is a discussion on this direction but at the moment teachers are not evaluated. The research examines the relationship between the introduction of a teachers’ evaluation system and the promotion of professional communities in schools; teachers’ evaluation is considered useful for the development of a school as a professional community. The study of teachers’ evaluation systems, while not disregarding economic analysis, must be associated by a pedagogical vision on the school and the teaching function, considering their founding elements; the prospect of the work accounts teaching professionalism as a complex prism of personal, organizational and community dimensions. It is investigated an innovative and systematic model used to evaluate teachers in the USA: Denver Professional Compensation System for Teachers, in order to offer food for thought even for Italy. The analysis highlighted the opportunities of the teachers’ evaluation system: the benefits of an evaluation in the service of professional practice, which provides assistance to career and to salary, which integrates different ways to assess the professionalism, and which is connected to decision making.

Les comparaisons temporelles sont essentielles pour s’évaluer. Plusieurs études se sont intéressées aux conséquences négatives d’être insatisfait à la suite de comparaisons temporelles désavantageuses (c.-à.-d., à la privation relative). Peu d’étude a toutefois examiné l’évolution de ce sentiment d’insatisfaction. Le présent mémoire propose que ressentir différents niveaux d’insatisfaction au fil du temps, soit une trajectoire instable d’insatisfaction, affecte négativement le bien-être psychologique. Trois études expérimentales ont été menées. Les résultats révèlent que percevoir une trajectoire instable d’insatisfaction affecte négativement le bien-être psychologique. Une quatrième étude corrélationnelle a été menée au Kirghizstan afin d’examiner si les perceptions d’insatisfaction et d’instabilité mesurées à fil de l’histoire d’un groupe sont associées au bien-être psychologique lors de changements sociaux. Les résultats suggèrent que percevoir un haut niveau d’instabilité et d’insatisfaction au fil du temps est associé négativement au bien-être. Les implications théoriques et méthodologiques sont discutées. / Temporal comparisons are essential for one’s self evaluation. Several studies have examined the negative consequences of being dissatisfied after unfavorable temporal comparisons (i.e., having a feeling of relative deprivation). However, few studies have examined how changes in relative deprivation affect well-being. The present master’s thesis proposes that feeling different levels of relative deprivation over time (i.e., an unstable trajectory of relative deprivation) negatively affects people’s well-being. Three experimental studies were conducted. Results showed that perceiving an unstable trajectory of relative deprivation negatively affects well-being. A fourth correlational study was conducted in Kyrgyzstan in order to examine whether perceptions of relative deprivation and instability measured retrospectively across a group’s history are associated with people’s well-being in times of social change. Results suggested that perceiving high instability and a high level of relative deprivation over time is negatively associated with well-being. The theoretical and methodological implications are discussed.

Prompting students to self-explain during problem solving has proven to be an effective instructional strategy across many domains. However, despite being called “domain general”, very little work has been done in areas outside of math and science. In this dissertation, I investigate whether the self-explanation effect holds when applied in an inherently different type of domain, second language grammar learning. Through a series of in vivo experiments, I tested the effects of using prompted self-explanation to help adult English language learners acquire the English article system (e.g., teaching students the difference between “I saw a dog” versus “I was the dog”). In the pilot study, I explored different modalities of self-explanation (free-form versus menu-based), and in Study 1, I looked at transfer effects between practice and self-explanation. In the studies that followed, I added an additional deep processing manipulation (Study 2: analogical comparisons) and a strategy designed to increase the rate of practice and information processing (Study 3: worked example study). Finally, in Study 4, I built and evaluated an adaptive self-explanation tutor that prompted students to self-explain only when estimates of prior knowledge were low. Across all studies, results show that self-explanation is an effective instructional strategy in that it leads to significant pre- to post-test learning gains, but it is inefficient compared to tutored practice. In addition to learning gains, I compared learning process data and found that both self-explanation and practice lead to similar patterns of learning and there was no evidence in support of individual differences. This work makes contributions to learning sciences, second language acquisition (SLA), and tutoring system communities. It contributes to learning sciences by demonstrating boundary conditions of the self-explanation effect and cautioning against broad generalizations for instructional strategies, suggesting instead that strategies should be aligned to target knowledge. This work contributes to second language acquisition theory by demonstrating the effectiveness of computer-based tutoring systems for second language grammar learning and providing data that supports the benefits of explicit instruction. Furthermore, this work demonstrates the relative effectiveness of a broad spectrum of explicit learning conditions. Finally, this work makes contributions to tutoring systems research by demonstrating a process for data-driven and experiment-driven tutor design that has lead to significant learning gains and consistent adoption in real classrooms.

There are a variety of studies that show that absolute income is positively correlated with individual well-being, but find at the same time that average income of the reference group (comparison income) affects individual well-being most often negatively (Clark et al., 2008). Although the results allover the literature are quite consistent, there is a large variety how the reference group is defined. For example, some authors assume that people compare themselves with people living in the same area (Luttmer, 2005; Graham & Felton, 2006) or with people inside the same age range (McBride, 2001). Others define the reference group more precisely and assume that people compare themselves with people of same age, same education and same area of living (Ferrer-i-Carbonell, 2005). However, to the best of my knowledge, there is no systematic empirical research on the impact of different reference group specifications on life satisfaction in happiness regressions. Therefore, I investigate in this master thesis to what extent different reference group specifications alter the statistical impact of comparison income on happiness regarding sign, magnitude and statistical significance. The results show that the specification of the reference group matters, since some specifications produce significant and others produce insignificant coefficients. However, the results also show that the sub-sample treated has a considerable impact on sign and statistical significance of the reference groups defined.

Le point de départ de cette recherche concerne la question suivante : l’acquisition de la lecture, peut-il être plus ou moins efficace en fonction de la langue dans laquelle il s’effectue? Deux catégories pour classer les langues on été définies dans ce travail. Premièrement, la notion de famille linguistique est à la base d’une description des langues à partir d'une perspective historique et culturelle. Deuxièmement la notion de profondeur orthographique est mobilisée, celle-ci différencie les langues en fonction de la correspondance entre l'orthographe et la phonétique. Ces catégories ont été mises en rapport avec les bases de données PIRLS 2001 et 2006 (étude internationale sur la lecture menée par l'IEA), afin de relier la performance en lecture et la langue dans laquelle les élèves ont répondu au test. Toutefois, il est clair que la langue n'est pas un facteur isolé, car elle fait partie d'un ensemble complexe de déterminants; ainsi, des facteurs liés aux élèves et au milieu scolaire ont également été incorporés dans l'étude. En outre, il a été tenu compte de la multidimensionnalité du processus de lecture, en distinguant dans les analyses les différents domaines mesurés par l’enquête : lecture d'informative, littéraire, et compréhension des processus d'ordre complexe et simple. Pour répondre aux questions de cette recherche nous avons élaboré un modèle statistique hiérarchique capable de rendre compte de la relation entre la compréhension de la lecture, la langue et les facteurs qui y sont associés. En dernière analyse, les facteurs contextuels (individuels et scolaires) se sont révélés être plus importants que la langue elle-même. En outre, les déterminants du niveau en lecture dépendent des systèmes éducatifs observés dans cette enquête. / The starting point of this research is the question, may reading acquisition be more or less effective depending on the language in which it is perform? Two categories for classifying the languages have been developed. First the notion of linguistic family is employed to describe the languages from a cultural and historical perspective. Secondly, the notion of orthographic depth is used for differentiating the languages according to the correspondence between orthography and phonetic. These categories have been related to the databases PIRLS 2001 and 2006 (international assessments about reading developed by the IEA), the aim being to connect reading achievement to the language in which students answered the test. However, it is clear that the language is not an isolated factor, but part of a complex structure of determinants of reading. Therefore, factors related to students and schools have also been incorporated to this research. Moreover, the multidimensionality of the reading process has been taken into account by distinguishing in the analysis the different aspects that made the process according to PIRLS: informative reading, literary reading, process comprehension of high and low order. To answer to the questions proposed by this research a hierarchical statistical model (multilevel) was developed, it was able to account for the connection between reading achievement, language and other associated factors. As a result, contextual factors (home and school) were more significant than language. Moreover, determinacy may vary if taking into account educational systems.
