This dissertation analyzes the theological and ethical convictions that led the people of the Plateau Vivarais-Lignon to shelter thousands of refugees between 1939 and 1945. It does so by examining the themes of narrative identity, hospitality, character formation, nonviolence, and the contextual witness of church tradition. Though a number of studies have been published about the rescue activity in this region of France during World War II, none have thoroughly analyzed the theological nature of this activity. Using the Plateau Vivarais-Lignon as a case study in theological ethics, the dissertation draws on historical sources as well as the work of contemporary theologians and ethicists to understand, interpret, and analyze the witness of this community. After situating its rescue and resistance work within the Huguenot narrative of persecution and exile, I examine the theological convictions of the Reformed pastor of Le Chambon-sur-Lignon, André Trocmé, who played a key role in making the Plateau a place of refuge during the Holocaust. The study highlights the importance of narrative in the actions of this community and discusses the relationship between narrative, character, and ethics. It then examines the nonviolent commitments of key leaders of the rescue effort, using this analysis as a springboard to engage in broader theological reflection about the ethics of nonviolence. After examining the radical hospitality practiced on the Plateau in light of biblical narratives and Reformed history, I investigate the counter-cultural nature of Christian hospitality. The study concludes by analyzing the nature and witness of the church in light of the legacy of the Plateau Vivarais-Lignon. The dissertation suggests that increased academic and ecclesial attention be given to the relationship between narrative and character, the counter-cultural shape of Christian hospitality, and the active nature of nonviolence. It presents an in-depth analysis of the theological and ethical convictions of the people of the Plateau Vivarais-Lignon, arguing that their witness has ongoing significance for communities of faith as they grapple with how to form disciples, relate to the wider society, welcome strangers, and communicate God's shalom in a world of violence.

This thesis is a study of military memorials and commemoration with a focus on Anglo-American practice. The main question is: How has history defined military memorials and commemoration and how have they changed since the 19th century. In an effort to resolve this, the work examines both historic and contemporary forms of memorials and commemoration and establishes that remembrance in sites of collective memory has been influenced by politics, conflicts and religion. Much has been written since the Great War about remembrance and memorialization; however, there is no common lexicon throughout the literature. In order to better explain and understand this complex subject, the work includes an up-to-date literature review and for the first time, terminologies are properly explained and defined. Particular attention is placed on recognizing important military legacies, being familiar with spiritual influences and identifying classic and new signs of remembrance. The thesis contends that commemoration is composed of three key principles – recognition, respect and reflection – that are intractably linked to the fabric of memorials. It also argues that it is time for the study of memorials to come of age and proposes Memorialogy as an interdisciplinary field of study of memorials and associated commemorative practices. Moreover, a more modern, adaptive, General Classification System is presented as a means of identifying and re-defining memorials according to certain groups, types and forms. Lastly, this thesis examines how peacekeeping and peace support operations are being memorialized and how the American tragic events of 11 September 2001 and the war in Afghanistan have forever changed the nature of memorials and commemoration within Canada and elsewhere. This work goes beyond what has been studied and written about over the last century and provides a deeper level of analysis and a fresh approach to understanding the field of Memorialogy.

Parkinson’s disease (PD) is a progressive neurodegenerative disorder characterised by the loss of midbrain dopaminergic neurons from the substantia nigra pars compacta(SNpc), which results in motor, cognitive and psychiatric symptoms. Evidence supports a role for the mitogen-activated protein kinase p38 in the demise of dopaminergic neurons, while mitogen-activated protein kinase phosphatase-1 (MKP-1), which negatively regulates p38 activity, has not yet been investigated in this context. Inflammation may also be associated with the neuropathology of PD due to evidence of increased levels of proinflammatory cytokines such as interleukin-1β (IL-1β) within the SNpc. Because of the specific loss of dopaminergic neurons in a discreet region of the brain, PD is considered a suitable candidate for cell replacement therapy but challenges remain to optimise dopaminergic cell survival and morphological development. The present thesis examined the role of MKP-1 in neurotoxic and inflammatory-induced changes in the development of midbrain dopaminergic neurons. We show that MKP-1 is expressed in dopaminergic neurons cultured from embryonic day (E) 14 rat ventral mesencephalon (VM). Inhibition of dopaminergic neurite growth induced by treatment of rat VM neurons with the dopaminergic neurotoxin 6- hydroxydopamine (6-OHDA) is mediated by p38, and is concomitant with a significant and selective decrease in MKP-1 expression in these neurons. Dopaminergic neurons transfected to overexpress MKP-1 displayed a more complex morphology and contributed to neuroprotection against the effects of 6-OHDA. Therefore, MKP-1 expression can promote the growth and elaboration of dopaminergic neuronal processes and can help protect them from the neurotoxic effects of 6-OHDA. Neural precursor cells (NPCs) have emerged as promising alternative candidates to fetal VM for cell replacement strategies in PD. Here we show that phosphorylated (and thus activated) p38 and MKP-1 are expressed at basal levels in untreated E14 rat VM NPCs (nestin, DCX, GFAP and DAT-positive cells) following proliferation as well as in their differentiated progeny (DCX, DAT, GFAP and βIII-tubulin) in vitro. Challenge with 6-OHDA or IL-1β changed the expression of endogenous phospho-p38 and MKP-1 in these cells in a time-dependent manner, and so the dynamic balance in expression may mediate the detrimental effects of neurotoxicity and inflammation in proliferating and differentiating NPCs. We demonstrate that there was an up-regulation in MKP-1 mRNA expression in adult rat midbrain tissue 4 days post lesion in two rat models of PD; the 6-OHDA medial forebrain bundle (MFB) model and the four-site 6-OHDA striatal lesion model. This was concomitant with a decrease in tyrosine hydroxylase (TH) mRNA expression at 4 and 10 days post-lesion in the MFB model and 10 and 28 days post-lesion in the striatal lesion model. There was no change in mRNA expression of the pro-apoptotic gene, bax and the anti-apoptotic gene, bcl-2 in the midbrain and striatum. These data suggest that the early and transient upregulation of MKP-1 mRNA in the midbrain at 4 days post-6-OHDA administration may be indicative of an attempt by dopaminergic neurons in the midbrain to protect against the neurotoxic effects of 6-OHDA at later time points. Collectively, these findings show that MKP-1 is expressed by developing and adult dopaminergic neurons in the midbrain, and can promote their morphological development. MKP-1 also exerts neuroprotective effects against dopaminergic neurotoxins in vitro, and its expression in dopaminergic neurons can be modulated by inflammatory and neurotoxic insults both in vitro and in vivo. Thus, these data contribute to the information needed to develop therapeutic strategies for protecting midbrain dopaminergic neurons in the context of PD.

The main objective of this thesis is the critical analysis of the evolution of the criminal justice systems throughout the past decade, with special attention to the fight against transnational terrorism. It is evident – for any observer - that such threats and the associated risk that terrorism entails, has changed significantly throughout the past decade. This perception has generated answers – many times radical ones – by States, as they have committed themselves to warrant the safety of their populations and to ease a growing sentiment of social panic. This thesis seeks to analyse the characteristics of this new threat and the responses that States have developed in the fight against terrorism since 9/11, which have questioned some of the essential principles and values in place in their own legal systems. In such sense, freedom and security are placed into perspective throughout the analysis of the specific antiterrorist legal reforms of five different States: Israel, Portugal, Spain, the United Kingdom and the United States of America. On the other hand, in light of those antiterrorist reforms, it will be questioned if it is possible to speak of the emergence of a new system of criminal justice (and of a process of a convergence between common law and civil law systems), built upon a control and preventive security framework, significantly different from traditional models. Finally, this research project has the fundamental objective to contribute to a better understanding on the economic, social and civilization costs of those legal reforms regarding human rights, the rule of law and democracy in modern States.

Vietnam launched its first-ever stock market, named as Ho Chi Minh City Securities Trading Center (HSTC) on July 20, 2000. This is one of pioneering works on HSTC, which finds empirical evidences for the following: Anomalies of the HSTC stock returns through clusters of limit-hits, limit-hit sequences; Strong herd effect toward extreme positive returns of the market portfolio;The specification of ARMA-GARCH helps capture fairly well issues such as serial correlations and fat-tailed for the stabilized period. By using further information and policy dummy variables, it is justifiable that policy decisions on technicalities of trading can have influential impacts on the move of risk level, through conditional variance behaviors of HSTC stock returns. Policies on trading and disclosure practices have had profound impacts on Vietnam Stock Market (VSM). The over-using of policy tools can harm the market and investing mentality. Price limits become increasingly irrelevant and prevent the market from self-adjusting to equilibrium. These results on VSM have not been reported before in the literature on Vietnam’s financial markets. Given the policy implications, we suggest that the Vietnamese authorities re-think the use of price limit and give more freedom to market participants.

In this work we revisit the problem of the hedging of contingent claim using mean-square criterion. We prove that in incomplete market, some probability measure can be identified so that becomes -martingale under .This is in fact a new proposition on the martingale representation theorem. The new results also identify a weight function that serves to be an approximation to the Radon-Nikodým derivative of the unique neutral martingale measure.

This study focuses on those substantial changes that characterize the shift of Vietnam’s macroeconomic structures and evolution of micro-structural interaction over an important period of 1991-2008. The results show that these events are completely distinct in terms of (i) Economic nature; (ii) Scale and depth of changes; (iii) Start and end results; and, (iv) Requirement for macroeconomic decisions. The study rejected a suspicion of similarity between the contagion of the Asian financial crisis in 1997-98 and economic chaos in the first half of 2008 (starting from late 2007). The depth, economic settings of, and interconnection between macro choices and micro decisions have all grown up significantly, partly due to a much deeper level of integration of Vietnam into the world’s economy. On the one hand, this phenomenon gives rise to efficiency of macro level policies because the consideration of micro-structural factors within the framework has definitely become increasingly critical. On the other and, this is a unique opportunity for the macroeconomic mechanism of Vietnam to improve vastly, given the context in which the national economy entered an everchanging period under pressures of globalization and re-integration. The authors hope to also open up paths for further empirical verifications and to stress on the fact that macro policies will have, from now on, to be decided in line with changing micro-settings, which specify a market economy and decide the degree of success of any macroeconomic choices.
