The EU is faced with problems related to the unrestricted access to national welfare states of mobile EU workers. These problems are mainly framed by the growing opposition to the free movement of workers. The strongest contributing factor to these negative attitudes has commonly said to be actor-based, i.e. the media or political elites. However, more recent research has been shifting the focus to institutions as explanatory factor. I raise the question of to what extent individuals’ attitudes towards the free movement of workers are associated with their exposure to different welfare state institutional contexts. More specifically I explore the role of “earnings-relatedness” in specific social insurances for the attitudes of potential benefit claimants. Analyzing 12 EU/EFTA countries who are net receivers of mobile EU workers I find that in welfare state contexts with a high degree of earnings-relatedness the opposition to free movement is significantly lower than otherwise among the unemployed. Furthermore, I discover that these observations seem to vary depending on what part of the social insurance system one is analyzing.

Der Einfluß der mütterlichen Verwandtschaft auf das soziale Verhalten ist eingehend für viele Primatenarten untersucht worden, es ist jedoch schwierig die Bedeutung der Verwandtenselektion auf die Evolution von sozialem Verhalten zu bewerten, wenn Studien auf die mütterliche Verwandtschaft begrenzt sind und die väterliche Verwandtschaft dabei völlig ignorieren. Das Ziel der vorliegenden Dissertation war die Untersuchung des Ausmaßes der väterlichen Verwandtschaft und ihr Einfluß auf die sozialen Beziehungen zwischen adulten Weibchen in einer freilebenden Gruppe von Rhesusaffen (Macaca mulatta) auf der Insel Cayo Santiago. Die wichtigsten Resultate können folgendermaßen zusammengefaßt werden: Erstens, zur Beurteilung des Ausmaßes der väterlichen Verwandtschaft wurde die Vaterschaft der zwischen 1993 und 1998 geborenen Kindern der Studiengruppe bestimmt. Die Resultate zeigten, dass die Reproduktion der Männchen innerhalb der Untersuchungszeit nicht gleich verteilt war, einige wenige Männchen zeugten viele Nachkommen, aber die Mehrzahl der potentiellen Väter reproduzierten sich gar nicht oder nur wenig. Dies führte zu einer Verwandtschaftsstruktur in der fast alle im Untersuchungszeitraum geborenen Kinder mindestens ein väterliches Halbgeschwister mit geringer Altersdifferenz hatten, d.h. entweder im selben Alter (74%) oder maximal zwei Jahre jünger oder älter als es selbst (15%). Wenn auch bei anderen Primatenarten die Reproduktion auf einige wenige Männchen beschränkt ist, dann sollte die Bedeutung der väterlichen Verwandtschaft für Primaten neu bewertet werden. Eine der wichtigsten Konsequenzen der ungleichen Reproduktion der Männchen wäre nämlich, dass viele Individuen mehr väterliche, als mütterliche Halbgeschwister in ihrem Leben haben. Zweitens, um den Einfluß der väterlichen Verwandtschaft auf die sozialen Beziehungen unter adulten Weibchen zu bewerten, wurden affiliative und aggressive Interaktionen von 34 Fokusweibchen und ihren sozialen Partnern beobachtet, die entweder ihre mütterlichen Halbschwestern, ihre väterlichen Halbschwestern oder nichtverwandte Weibchen waren. Die vorliegende Untersuchung bestätigte, dass mütterliche Halbschwestern die engsten affiliativen Beziehungen haben. Das wahrscheinlich wichtigste Resultat dieser Studie ist der Befund, dass adulte Weibchen deutlich häufiger affiliativ mit ihren väterlichen Halbschwestern als mit Nichtverwandten interagierten. Die Erkennung der väterlichen Halbschwestern war deutlicher unter Weibchen gleichen Alters als unter Weibchen unterschiedlichen Alters, wobei die affiliativen Interaktionen mit zunehmender Altersdifferenz (gemessen in Jahren) abnahmen. Dies deutet darauf hin, dass Altersnähe einen zusätzlichen regulierenden Einfluß auf affiliatives Verhalten hatte. Beweise dafür, dass sich väterliche Verwandte erkennen können, sind nur in Bezug auf affiliative Interaktionen, nicht aber auf dyadische Aggression gefunden worden, was eine kontextabhängige Verwandtenerkennung annehmen läßt. Drittens, bei der Einbeziehung weiterer Verwandtschaftskategorien zeigten die Daten, dass mütterliche Verwandte auch bei konstant gehaltenem Verwandtschaftsgrad deutlich gegenüber väterlichen Verwandten bevorzugt wurden. Dies weist darauf hin, dass die mütterliche Verwandtschaft in der untersuchten Gruppe einen größeren Einfluß auf die sozialen Beziehungen adulter Rhesusaffenweibchen hatte als die väterliche Verwandtschaft. Affiliative sowie aggressive Interaktionen nahmen mit sinkendem Verwandtschaftsgrad ab, aber entfernte Verwandte unterschieden einander immer noch von Nichtverwandten, was der Existenz einer Verwandschaftsschwelle widerspricht. Viertens, schließlich wurde die väterliche Verwandtschaft in Bezug auf Koalitionsbildungen untersucht. Eine Koalition wird gebildet, wenn ein Individuum in ein laufenden Konflikt zwischen zwei Kontrahenten eingreift, um eine Partei gegen die andere zu unterstützen. Weibliche Rhesusaffen unterstützten am häufigsten ihre mütterliche Halbschwestern. Außerdem unterstützten sie Nichtverwandte gleichen Alters häufiger als Nichtverwandte unterschiedlichen Alters. Weibchen unterstützten ihre väterlichen Halbschwestern nicht häufiger als Nichtverwandte, aber die Daten könnten auf einen indirekten Beweis der väterlichen Verwandtenerkennung hinweisen, da Weibchen dazu tendierten gegen ihre väterlichen Halbschwestern seltener zu intervenieren als gegen Nichtverwandte. Dieser Befund könnte durch die Tatsache bedingt sein, dass väterliche Halbschwestern sehr unterschiedliche Dominanzränge einnehmen können, währenddessen mütterliche Halbschwestern immer benachbarte Dominanzränge haben, was zur Folge hat, dass ein rangtiefes Weibchen ihrer väterlichen Halbschwester nicht wirklich helfen kann, da sie ein viel höheres Vergeltungsrisiko auf sich nimmt, wenn sie in einen Konflikt zwischen zwei ranghöhere Kontrahenten interveniert. Als einen Kompromiß könnten Weibchen statt dessen vermeiden gegen ihre väterlichen Halbschwestern zu intervenieren, was darauf hindeuten könnte, dass individuelle Zwänge bezüglich der eigenen Konkurrenzfähigkeit eine bedeutende Rolle bei der Koalitionsbildung spielen. Mütterliche und väterliche Halbschwestern zeigten zudem einen stärkeren Trend zu "reciprocity" und "interchange" als Nichtverwandte und gaben einander einen höheren Anteil an kostenintensiven Unterstützungen. Schließlich unterstreichen die Ergebnisse dieser Studie deutlich, dass Vertrautheit zwischen Individuen durch frühkindliche Bindungen mindestens auf zwei Wegen erfolgen kann: (i) Mütter vermitteln Vertrautheit zwischen ihren Kindern (die mütterliche Halbgeschwister sind) aufgrund der durch die Laktation bedingten engen Mutter-Kind Bindung und (ii) Altersnähe vermittelt mehr Vertrautheit zwischen Altersgenossen (die entweder väterliche Halbgeschwister oder Nichtverwandte sind), die wichtige Lebensabschnitte wie z.B. Kindheit, Menstruationsbeginn, Schwangerschaft oder Mutterschaft zu ähnlichen Zeiten durchlaufen, während Weibchen unterschiedlichen Alters dies nicht tun. In jedem Fall brauchen väterliche Halbgeschwister neben der Vertrautheit zu ihren Altersgenossen noch einen zusätzlichen Mechanismus wie z.B. das "phenotype matching" um innerhalb ihrer Altersgenossen wirklich zwischen väterlichen Halbgeschwistern und Nichtverwandten zu unterscheiden. / The impact of maternal kinship on social behaviour has been studied in detail for many primate species, but it is difficult to assess the importance of kin selection in shaping the evolution of social behaviour when studies are limited to maternal kin, completely ignoring paternal kinship. This thesis aimed to investigate the extent of paternal kinship and its impact on the social relationships among adult females in one group of free-ranging rhesus macaques (Macaca mulatta) living on the island of Cayo Santiago. The main findings can be summarised as follows: Firstly, in order to access the extent of paternal kinship, paternity has been analysed for all infants of the study group born between 1993 and 1998. Results revealed that male reproduction was highly skewed over the study period as few males have sired a high number of offspring, but the majority of potential sires have sired no or few offspring. This created a kinship structure in which nearly all animals born during the study period had at least one paternal half-sibling in close age proximity, i.e., either of the same age (74%) or within a two-year age difference of themselves (15%). Assuming that male reproductive success is also skewed in other primate species, then the importance of paternal kinship in primate societies should be re-emphasised. One of the most important consequences of male reproductive skew is that many individuals will have more paternal than maternal half-siblings during their life time. Secondly, in order to access the impact of paternal kinship on the social relationships among adult females, focal data on affiliation and aggression have been collected on 34 adult females with respect to their social partners who were either their maternal half-sisters, paternal half-sisters or unrelated females. The present study confirmed that the closest affiliative relationships characterise maternal half-sisters. Probably the most important result of this study was the finding that adult females were significantly more affiliative with their paternal half-sisters than with their non-kin. The recognition of paternal sisters was more pronounced among females of the same age than among females of different age, with a decrease in affiliation as the exact age difference (measured in years) increased among paternal half-sisters. This indicates that age proximity had an additional regulatory effect upon affiliative behaviour. However, evidence for paternal kin discrimination was only found with respect to affiliation, but not with respect to dyadic aggression suggesting context-dependent kin discrimination. Thirdly, when more kin categories were included in the analysis, adult females showed a strong bias towards maternal kin in comparison to paternal kin. This bias towards maternal kin when the degree of relatedness was held constantly suggests, that maternal kinship had a larger impact on the social relationships among adult female rhesus macaques than paternal kinship at least in the study group. Both affiliation and aggression declined with decreasing degrees of relatedness, but distant kin still differentiated each other from non-kin contradicting the existence of a relatedness threshold. Fourthly, paternal kinship was finally investigated with respect to coalition formation. A coalition is formed when an individual intervenes in an ongoing conflict between two opponents in order to support one party against the other. Female rhesus macaques intervened most often on behalf of their maternal half-sisters. In addition, unrelated female peers supported each other more often than unrelated female non-peers. Females did not support their paternal half-sisters more often than non-kin, but data may indicate indirect evidence for paternal kin discrimination as females tended to target their paternal half-sisters less often than non-kin. This finding might be due to the fact, that paternal half-sisters can be very different in rank, while maternal half-sisters are of adjacent rank, implying that a low-ranking female cannot provide actual help to her paternal half-sisters, as she may risk a higher probability of retaliation when intervening in a conflict between two higher-ranking opponents. As a compromise, females may instead avoid to target their paternal half-sisters, suggesting that constraints to an individuals own competitive ability play an important role in coalition formation. Maternal and paternal half-sisters showed a stronger trend in reciprocity and interchange than non-kin and also provided a higher proportion of costly interventions towards each other. Finally, the results of the present study strongly suggest that familiarity among individuals can arise through association in early development by at least two alternatives: (i) mothers mediating familiarity among their offspring (which are maternal half-siblings) caused by the close mother-offspring relationship during lactation and (ii) age proximity is mediating familiarity among age mates (including both paternal related and unrelated peers) as peers go through important life history stages such as infancy, menarche, pregnancy or motherhood at similar times while females of different age do not. In any case, paternal half-siblings additionally need a mechanism such as phenotype matching to discriminate paternal half-siblings from non-kin even within their peer group.

Diversity has, over the last few decades, become a burning issue on the agenda of most companies. Current diversity-related interventions are mainly based on behaviouristic and socio-cognitive approaches. In this research diversity was approached from the systems psychodynamic paradigm. The general aim was to gain an understanding of the diversity dynamics that manifests in an South African diversity experience. The literature review focussed on diversity in the workplace, on the group relations training model, and on the application of the group relations training model to diversity. Qualitative research was done by interviewing a sample of 15 delegates who attended the November 2000 Robben Island Diversity Experience. These unstructured interviews were used to obtain in-depth information about the participant's experience and the data was analysed hermeneutically. The emerging themes were `crossing the boundary, engage the new world, the ties that bind, being imprisoned, the struggle, the road to reconciliation, integration and healing, back to the future and the crucible'. It is recommended that South African organizations make more use of the systems psychodynamic approach to study the manifestations of diversity dynamics. The aim is not to replace the other approaches to diversity, but to add a perspective that can enhance awareness and sensitivity to the covert, unconscious and irrational forces that impact on diversity. / Industrial and Organisational Psycology / M.

The purpose of this study was to gain a better understanding of how a problem-determined system developed around a case of drug addiction within the context of a system of relatedness. The epistemological framework informing this qualitative study was constructivism. The six participants who took part in the study represent the most prominent role players in the particular context of living. The individual battling with drug addiction, his parents, older sister, maternal grandmother and maternal aunt were interviewed. The methods of data collection employed were semi-structured interviews, a family-chronological event chart, genograms, and an eco-map. The interviews were interpreted using the hermeneutic approach. The different themes that emerged from each participant’s story were integrated in relation to each other and with respect to the collaborative sources of data. The most dominant themes extracted within this study are the initial reactions to Andrew’s drug addiction, life changes experienced due to Andrew’s drug addiction, support, as well as the meanings attributed to Andrew’s drug addiction. Further research into problem-determined systems in different cultures is recommended. / Psychology / Thesis (M.A. (Clinical Psychology)) Psychology

It is argued that key to gender empowerment and the success of women in leadership is the exploration of the work-family interface which serves to enhance the understanding of issues faced by women leaders as they navigate through their domestic and management roles. It is also contended that work-family scholarship move beyond the study of objective characteristics, and the overt conscious level of functioning of the interface, to an understanding of the intra-psychic experiences of individuals. Recognising the preoccupation with the role strain perspective, it is argued that work-family scholarship adopts a more balanced view and considers the positive and negative effects of participating in multiple roles. Hence the general aim of this qualitative study was to understand the systems psychodynamics underlying the work-family interface that influence the processes of enrichment and conflict among managerial women in the public sector. In the empirical study, data was gathered using the organisational role analysis method, and analysed by means of systems psychodynamic discourse analysis. Six themes and their related subthemes were identified, namely anxiety and conflict, identity, boundary management, authority, role and task. The findings explored the manner in which these behavioural dynamics of participants, and their family and organisational systems interacted, mutually influencing each other, and shaping the way managerial women found, made and took up their domestic and management roles at the work-family interface. This led to resource generation and role enhancement, or resource depletion and role strain in the role (domestic or management). Through relatedness, projection and introjection between the systems and roles, the quality of life in one role influenced the other role, promoting enrichment and conflict at the interface. This study concluded that both enrichment and conflict occur at the interface. While participants oscillated between experiencing enrichment and conflict, some participants experienced more enrichment than conflict, while others experienced more conflict than enrichment at the work-family interface. The extent to which enrichment or conflict occurred between the systems was mediated by participants’ ability to self-contain, and/or the receiving system’s ability to serve as a “good enough” holding environment containing the anxieties experienced in the other role. / D.

Semantic distance is a measure of how close or distant in meaning two units of language are. A large number of important natural language problems, including machine translation and word sense disambiguation, can be viewed as semantic distance problems. The two dominant approaches to estimating semantic distance are the WordNet-based semantic measures and the corpus-based distributional measures. In this thesis, I compare them, both qualitatively and quantitatively, and identify the limitations of each. This thesis argues that estimating semantic distance is essentially a property of concepts (rather than words) and that two concepts are semantically close if they occur in similar contexts. Instead of identifying the co-occurrence (distributional) profiles of words (distributional hypothesis), I argue that distributional profiles of concepts (DPCs) can be used to infer the semantic properties of concepts and indeed to estimate semantic distance more accurately. I propose a new hybrid approach to calculating semantic distance that combines corpus statistics and a published thesaurus (Macquarie Thesaurus). The algorithm determines estimates of the DPCs using the categories in the thesaurus as very coarse concepts and, notably, without requiring any sense-annotated data. Even though the use of only about 1000 concepts to represent the vocabulary of a language seems drastic, I show that the method achieves results better than the state-of-the-art in a number of natural language tasks. I show how cross-lingual DPCs can be created by combining text in one language with a thesaurus from another. Using these cross-lingual DPCs, we can solve problems in one, possibly resource-poor, language using a knowledge source from another, possibly resource-rich, language. I show that the approach is also useful in tasks that inherently involve two or more languages, such as machine translation and multilingual text summarization. The proposed approach is computationally inexpensive, it can estimate both semantic relatedness and semantic similarity, and it can be applied to all parts of speech. Extensive experiments on ranking word pairs as per semantic distance, real-word spelling correction, solving Reader's Digest word choice problems, determining word sense dominance, word sense disambiguation, and word translation show that the new approach is markedly superior to previous ones.

Ideas of kinship play a significant role in structuring everyday life, and yet kinship has been neglected in Christian ethics, as well as moral philosophy and bioethics. Attention has been paid in these disciplines to the ethics of ‘family,’ but little regard has been paid to the fact that kinship is not a given, but is culturally contingent. The thesis seeks to remedy the neglect in recent Christian theological ethics by drawing on resources from the history of Christian thought and practice. It uses social anthropology both to unsettle the accounts of kinship used in Christian ethics, and to expose elements in Christian traditions of thought and practice relating to kinship. Notions of shared bodily substance, the house, gender and personhood recur cross-culturally in giving shape to kinship. By examining these four notions as they inform Christian thought and practice, a theological account is developed. Chapters dedicated to each of these four attempt to provide, in the first instance, a descriptive account of how the notion has structured Christian thought and practice in relation to kinship. Each chapter then turns, in the second instance, to a critical mode, offering a theological treatment of the chapter topic as it bears on kinship. The thesis concludes that kinship in Christ should be considered normatively primary for the Christian, but also that there are ways in which Christians have honoured this kinship in Christ by organising and playing out kinship on a smaller scale. In detailing the distinctively Christian organising principles that structure some practices of kinship ‘in miniature,’ another common practice – the special privileging of the blood tie in structuring kinship – is singled out for critique.
