The purpose of this thesis is to analyze the dynamics of family support and public pension systems, and their impact on late-life happiness in contemporary South Korea. For this, three specific research questions, namely (1) the dynamics of intergenerational solidarity, public pension systems, and happiness; (2) the association between intergenerational solidarity and happiness; and (3) the association between public pension systems and happiness, are analysed by exploiting the Korean Longitudinal Study of Ageing. The analyses show that (1) the structural solidarity of older people is relatively stronger than of middle-aged people; (2) contacting is the key player in associational solidarity in later life; (3) middle-aged people supply more financial aid to their adult children than they receive from them, but the reverse applies to older people. Both middle-aged and older people actively exchange food, household items, and health-care supplies; (4) more older men receive the National Pension Scheme benefit than older women but the reverse is true for the Basic Old-Age Pension benefit; (5) the level of happiness in later life is very high but decreases as people age; (6) the number of adult children, frequency of contact, and amount of financial support are positively associated with the happiness of older people; and (7) the National Pension Scheme is positively associated with the happiness of older men while the Basic Old-Age Pension is negatively associated with the happiness of older people. The results suggest some policy implications for late-life happiness in contemporary South Korea. At the individual level, increased frequency of contact, availability of the children, and the amount of financial support can enhance late-life happiness. At the governmental level, the research suggests that the gendered structure of the National Pension Scheme and means-tested structure of the Basic Old-Age Pension should be reformed.

Through close textual analysis of 20^th century Czech anthropological texts from the Revivalist and Socialist periods and contemporary social research conducted after the Velvet Revolution, I demonstrate certain prominent discourses of identity developed in early Bohemian anthropology and their continuities in present day popular discourses. In each period, identity is deeply intertwined with teleological theories of history with Czech populations at the apex of cultural evolutionary development. In the Revivalist period this apex was believed to be the democratic nation state, transitioning to a Marxist nation state in the Socialist period, and in the contemporary period is conceived of as a neoliberal nation state. A major function of anthropology in the Revivalist and Socialist periods was to legitimate either period’s respective teleological theory and Czech possession of relevant values as 'objective' and 'natural' fact, a general mode of discourse which continued in the contemporary period in numerous editorials in the 1990s on the advantages of capitalism. The contemporary manifestation has particularly noteworthy consequences for the Roma minority, which I argue has provided Czech discourses with an ethnic category 'anti-thetical' to their own identity, providing a 'repository' for negative Czech self-stereotypes emerging from collaboration in the Socialist period.

The key topics of this project are intergenerational relationships, in the means of creating a positive approach towards ageing in elementary school kids. Regarding the fact of demographic ageing of the population, active engagement of seniors into public life and profitable usage of their experience are both a current matter. The theoretical part of this thesis discusses intergenerational relationships, defines old age as equal to other stages of life and questions various stances and values. The practical part offers guidance to the developing process of collaboration between elementary school kids and seniors, in the area of social studies. The aim of intergenerational cooperation is going to be, through conversations, shared memories and further work with them, the increase of kids' concern about modern history and enhancement of respect towards ageing, therefore prevention of ageism. KEY WORDS population ageing, ageism, intergeneration relationships, positive approach to ageing, family memory, memories, teaching, project - based learning, inspiration for schools, modern history

Il y a quatre chapitres dans cette thèse.Dans le premier chapitre, nous analysons les intéractions entre le marché interbancaire et le risque de défaut souverain dans un modèle d’équilibre général à deux pays, en focalisant sur la transmission de la crise financière récente et la politique monétaire non conventionnelle.Dans le deuxième chapitre, les effets de la dévaluation fiscale sur les indicateurs macroéconomiques et le bien être sont analysés en utilisant un modèle à deux pays en union monétaire o`u les variétés de biens et le commerce sont endogènes.Dans le troisième chapitre, l’impact du facteur démographique sur la croissance du secteur des services à long terme est mis en exergue.Dans le quatrième chapitre, on étudie les effets de la mobilité des travailleurs et de la mobilité du capital dans une union monétaire. / This thesis studies challenges for modern developped economies, including the structural change toward services, population ageing, weak labor mobility in the EMU and unconventional monetary policies after the 2008 financial crisis. The manuscript is divided into four chapters.In the first chapter, we analyze the interaction between interbank markets and default risk using a two-country dynamic general equilibrium model, with a focus on the transmission of the recent financial crisis and unconventional monetary policies.In the second chapter, we investigate the effects of fiscal devaluations on key macroeconomic aggregates and welfare using a two-country monetary-union model with endogenous varieties and endogenous tradability.In the third chapter, we study the impact of demographic factor and the growth of service sector by using a multi-sectoral OLG model, and effectuate counterfactual experiments in which the annual growth rate of young generation is ±1pp than the actual growth rate.In the fourth chapter, we study the potential interactions between financial integration and labor mobility in a currency union facing asymmetric shocks, and simulate the impacts of 2008 financial crisis under different mobility costs.

The main objective of this thesis is to analyze the problem of population ageing in terms of the cessation of professional activity (and especially premature labour market withdrawals) and non-medical care needs of persons who are dependent or have lost their autonomy, in order to provide the various public and private administrations active in these fields with some food for thought. / Doctorat en Sciences économiques et de gestion / info:eu-repo/semantics/nonPublished

Apart from rapid economic growth, China has also experienced significant demographic changes over the past few decades. The People's Republic of China's family planning policies led to a sharp drop in the fertility rate. This MS Thesis aims to assess the possible consequences of the family planning policies on future growth of Chinese economy. The theoretical part defines population policy, assess the connections between population growth and economic growth and deals with the development of population theory over the years. The analytical part describes the family planning policy in China, its principles and instruments. Next it identifies the possible consequences of the demographic changes caused by the drop in fertility rate. The last part of the thesis focuses on two economically most severe consequences - population ageing and shrinking working age population - and evaluates its implications on future growth of Chinese economy.

The concept of population ageing is a development issue that has received much attention due to the demographic transition that is occurring globally, marked by declining levels of fertility and mortality. Therefore, the implications of population ageing for older persons within the context of Social Development was examined from the perspective of government and non government officials. The study was confined to older persons and the policies and programmes implemented by the Department of Social Development. The study employed an exploratory research design within a qualitative paradigm. Semi-structured interviews and a questionnaire were distributed to officials in the nine provinces. Thirty six questionnaires were received and qualitative methods of data analysis were used to analyse and interpret the data. The main finding of the study is that there is congruence in what government officials and the non government officials view as implications for older persons. Central to this is that the issue of ageing does not receive attention on the agenda of government. The top five priorities for older persons are healthy ageing, economic security, community/home based care services for older persons, having care and support systems for older persons and an improved quality of life/poverty alleviation. Based on the demographic determinants of population ageing, the findings are that there will be an increased demand for services for older persons which might place a strain on the social assistance and health care programmes. The issue of ageing was viewed positively as an opportunity by government officials and pessimistically as a challenge by NGO’s. The most common problems in old age is a reliance on the younger generation and or the state for their care and support, abuse, high levels of illiteracy and the burden of care for their children and grandchildren. The future older person is likely to be in better health and better educated than the older person of today if the necessary public investments are made now in these areas. The study makes recommendations for the adoption of a South African plan of action on ageing, inter-sectoral budgeting, development of specialised programmes, review of current policies and legislation for older persons, strengthening the partnership with the NGO sector and facilitating ageing mainstreaming within government programmes. / Sociology / M.A. (Social Development)

Structure learning of Bayesian Networks (BNs) is an NP-hard problem, and the use of sub-optimal strategies is essential in domains involving many variables. One of them is to generate multiple approximate structures and then to reduce the ensemble to a representative structure. It is possible to use the occurrence frequency (on the structures ensemble) as the criteria for accepting a dominant directed edge between two nodes and thus obtaining the single structure. In this doctoral research, it was made an analogy with an adapted one-dimensional random-walk for analytically deducing an appropriate decision threshold to such occurrence frequency. The obtained closed-form expression has been validated across benchmark datasets applying the Matthews Correlation Coefficient as the performance metric. In the experiments using a recent medical dataset, the BN resulting from the analytical cutoff-frequency captured the expected associations among nodes and also achieved better prediction performance than the BNs learned with neighbours thresholds to the computed. In literature, the feature accounted along of the perturbed structures has been the edges and not the directed edges (arcs) as in this thesis. That modified strategy still was applied to an elderly dataset to identify potential relationships between variables of medical interest but using an increased threshold instead of the predict by the proposed formula - such prudence is due to the possible social implications of the finding. The motivation behind such an application is that in spite of the proportion of elderly individuals in the population has increased substantially in the last few decades, the risk factors that should be managed in advance to ensure a natural process of mental decline due to ageing remain unknown. In the learned structural model, it was graphically investigated the probabilistic dependence mechanism between two variables of medical interest: the suspected risk factor known as Metabolic Syndrome and the indicator of mental decline referred to as Cognitive Impairment. In this investigation, the concept known in the context of BNs as D-separation has been employed. Results of the carried out study revealed that the dependence between Metabolic Syndrome and Cognitive Variables indeed exists and depends on both Body Mass Index and age. / O aprendizado da estrutura de uma Rede Bayesiana (BN) é um problema NP-difícil, e o uso de estratégias sub-ótimas é essencial em domínios que envolvem muitas variáveis.

É possível usar a frequência de ocorrência (no conjunto de estruturas) como critério para aceitar um arco dominante entre dois nós e assim obter essa estrutura única. Nesta pesquisa de doutorado, foi feita uma analogia com um passeio aleatório unidimensional adaptado para deduzir analiticamente um limiar de decisão apropriado para essa frequência de ocorrência. A expressão de forma fechada obtida foi validada usando bases de dados de referência e aplicando o Coeficiente de Correlação de Matthews como métrica de desempenho. Nos experimentos utilizando dados médicos recentes, a BN resultante da frequência de corte analítica capturou as associações esperadas entre os nós e também obteve melhor desempenho de predição do que as BNs aprendidas com limiares vizinhos ao calculado. Na literatura, a característica contabilizada ao longo das estruturas perturbadas tem sido as arestas e não as arestas direcionadas (arcos) como nesta tese. Essa estratégia modificada ainda foi aplicada a um conjunto de dados de idosos para identificar potenciais relações entre variáveis de interesse médico, mas usando um limiar aumentado em vez do previsto pela fórmula proposta - essa cautela deve-se às possíveis implicações sociais do achado. A motivação por trás dessa aplicação é que, apesar da proporção de idosos na população ter aumentado substancialmente nas últimas décadas, os fatores de risco que devem ser controlados com antecedência para garantir um processo natural de declínio mental devido ao envelhecimento permanecem desconhecidos. No modelo estrutural aprendido, investigou-se graficamente o mecanismo de dependência probabilística entre duas variáveis de interesse médico: o fator de risco suspeito conhecido como Síndrome Metabólica e o indicador de declínio mental denominado Comprometimento Cognitivo. Nessa investigação, empregou-se o conceito conhecido no contexto de BNs como D-separação. Esse estudo revelou que a dependência entre Síndrome Metabólica e Variáveis Cognitivas de fato existe e depende tanto do Índice de Massa Corporal quanto da idade.

The theme of the diploma thesis is the policy-making process, specifically the process of making of the National Action Plan for Positive Ageing for the Period 2013 - 2017. It's about exploring its creation from the viewpoint of active members of the Government Council for Seniors and Population Ageing, who was discussing it at meetings. The theoretical framework - Multiple Streams Framework deals with the aspect of policy entrepreneurs. Using qualitative, semi-structured interviews and then analysis of qualitative data, it was possible to explore the means, used by policy entrepreneurs to promote their ideas at meetings. This diploma thesis does not only study the creation of an action plan, but also the identification of policy entrepreneurs, through document analysis. After that were analysed primary data from interviews with members of the Government Council for Seniors and Population Ageing, who had been appointed by The Ministry of labour and social affairs. The studied, strategic document is the answer to the demographic ageing phenomenon the population of the Czech Republic.
