The notion of prophecy is a Leitmotiv, both in Scripture and in the Church. However, the popular form of prophecy that is witnessed in the Church today is the charismatic prophecy manifestations in the Pentecostal- charismatic movement. Although the latter is now billed as the fastest growing Christian movement in church history, and has brought to the fore the biblical notion of the charisms of the Holy Spirit, the subject of charismatic prophecy has received limited attention in Pentecostal studies. There is therefore a gap in knowledge. The present study is an attempt to address the lacuna; it is an empirical-biblical investigation of the nature and significance of prophecy in the Pentecostal- charismatic experience. The study presents a particular thesis: that charismatic prophecy, as observed in Pentecostal- charismatic congregational settings in the African context, is sacramental in its nature and parakletic in its functional significance. Thus, the charismatic prophecy experience is viewed as an intense moment of a participatory interface between the divine Spirit and the human spirit in which the divine Spirit infuses the human conscious dimension with revelatory impulses. The experience is parakletic in the sense that it edifies, encourages, and comforts the church in congregational settings.

The aim of this thesis is to explore the “strange phenomenon” of the Intentional Christian Community Othona in Bradwell-on-Sea, Essex, Great Britain, founded in 1946 by Norman Motley, to cherish differences and diversity through reconciliation among nations that had been at war with each other. An old neglected chapel, St Peter-on-the-Wall, became the spiritual centre of this Community. A phenomenographic, auto-ethnographic and multi-dimensional research approach, designed to investigate and describe the Othona Community and its praxis and the researcher's involvement in it, is used for the empirical part of the thesis. The study seeks to discover a) the Lebenswelten ― or the world created by its life ― of the Othona Community, b) members'/participants' perception of the Community through interviews and Community literature, c) a way of understanding this “strange phenomenon” and its special charism with the help of an “endogenous theology”. This thesis shows that a two-fold encounter lies at the heart of the experience at Othona: encounter between a person and the “Other” (represented by the Stoep) and between a person and the “Wholly Other” (represented by the Chapel). Through examination of these encounters light is shed on the extraordinariness of Othona. The German term Heimat (a deeply spiritual home) is introduced here to encapsulate these “encounteral” experiences which induce a transformation of place and people alike. Theologically, the thesis claims that a combination of a Theology of Encounter and an understanding of Heimat can assist the appreciation of the Othona phenomenon as a Community of temporary withdrawal and restoration, where differences and a Kingdom model are experienced in narrative encounters on the margins by offering Heimat through belonging and significance.

This thesis is concerned with the role played by the Christian scholar ‘Ammār al-Baṣrī in theologizing in the Islamic milieu of the ‘Abbasids in the 9th century. His Kitāb al-Burhān, one of his only two surviving works, will therefore be thoroughly studied from two perspectives: the Islamic perspective as it is found in contemporary anti-Christian polemical texts; and the Christian perspective, through a comparison of ‘Ammār’s treatise with the works of Arab Christian theologians of his day. The present study aims at demonstrating the level of translatability of Christian theology into the Islamic intellectual milieu, as ‘Ammār al-Baṣrī saw it. It is therefore natural that we should examine Kitāb al-Burhān as an example of “contextualized” theology in Dār al-Islām. ‘Ammār’s Burhān stands a witness to the numerous attempts made by Arab Christians to reconcile their heritage (the world of Islam) with their inheritance (Christian theology). Such a reconciliation is essential for the future existence of Arab Christians, particularly in the Arab World.

This thesis uses a practical-theological methodology to explore the theology and spirituality of „spiritual warfare‟ that developed in the charismatic renewal from the 1960s. Beginning with a study of twelve charismatic Anglican pioneers, a detailed case study then explores spiritual warfare praxis in a charismatic Anglican congregation. The ensuing theological reflection focuses on the ontology of evil, through dialogue with Nigel Wright, Amos Yong, and Gregory Boyd, as well as Karl Barth and Walter Wink. The thesis argues for a positive ontology for evil powers, based on a charismatic hermeneutic of biblical texts; on the grounds that Jesus treated Satan and demons as real spiritual entities, the Pauline epistles refer to real evil spiritual powers in the heavenly realms, and charismatic experience supports this ontology. Such powers are in malevolent and wilful rebellion against God, deriving from a corrupted fallen angelic nature. A Trinitarian model of theological praxis is presented, focused on responding to the goodness of God in repentance; renewing faith in the believer‟s identity in Christ and His victory upon the cross; and resisting the devil in the power of the Spirit. This model emphasizes personal responsibility, helps bring freedom from fear, and re-connects with Anglican baptismal liturgy.

Taking the use of the logos in Ratzinger's Regensburg Lecture as its starting point, the thesis expands three horizons in Ratzinger studies. Firstly, it extends the understanding of Ratzinger as the author of a logos theology. Secondly, it shows how the Regensburg theme of the full breadth of reason, represented by the logos, is applied by Ratzinger in a critique of secular modernity. Thirdly, it claims that the logos theology of Joseph Ratzinger can provide a repair of the culture of human rights. The thesis argues that if human rights are set exclusively within the framework of secular modernity, they fall sick and fail to meet the criterion of inclusivity and universality. Set within the framework of a Ratzingerian logos theology, their power is strengthened and their promise of inclusivity and universality restored. The thesis calls for a mutually reparative dialogue about human rights, based on the full breadth of reason, between the three constituencies of Christianity, the religions and secular modernity. The thesis concludes that the Regensburg Lecture, far from damaging the dialogue with Islam, and with secular modernity, opens up a new intercultural bridge based on a mutually enriching engagement with a logos-based culture of human rights.

This dissertation examines the correspondence in theology, practice and social views between Early Quakers and John Wycliffe and John Hus (QWH), founders of the late-medieval heretical sects the Lollards and Hussites. It discusses the diversity of religious experience that characterized the first generation of ‘Early Quakers,’ and argues the end of early Quakerism as 1678, when the Quaker establishment completed enforcement of greater conformity in belief and practice. The dissertation examines Wycliffe and the Lollards and Hus and the Hussites, placing them in an experiential religious tradition and exploring their belief in the need to return to a primitive church in reaction to the perceived apostasy of the Catholic Church. By focusing on possible modes of dissemination of Wycliffe’s and Hus’ ideas and personal stories in works such as Foxe’s Book of Martyrs, the thesis concludes that there exists a close correspondence among QWH respecting the following characteristics: (1) accessibility of Christ’s message; (2) belief in the visible and invisible church; (3) biblical authority; (4) personal understanding of Scripture; (5) opposition to established churches; (6) return to a ‘primitive church’; (7) attitudes toward reforming society; (8) the imminence of Christ’s return; and (9) the role of women.

This thesis is a diachronic investigation of Lewi Pethrus’ ecclesiological thought from 1911 to 1974. The research employs Roger Haight’s transdenominational ecclesiology as its methodological framework. Since Haight’s methodology is based on a concrete ecclesiological method that emphasises the importance of a historical consciousness in ecclesiology, the study particularly focuses on the formative contexts that shaped Pethrus’ ecclesiology. The emphasis on formative contexts not only explains why certain ecclesiological concepts arose at particular points in Pethrus’ life but also clarifies why concepts were abandoned or developed over time. A vital part of Haight’s methodology is also to examine the religious values that remain constant and significantly form ecclesiological views. The thesis argues that Pethrus’ ecclesiology is shaped by a Pentecostal form of spirituality that has ‘loving Christ and loving neighbour’ as its core values. The combination of a Pentecostal form of spirituality and formative contexts is what makes Pethrus’ ecclesiology ‘Pentecostal’ and gives it its inner logic. The thesis concludes by taking this inner logic of Pethrus’ ecclesiology and hypothetically applying it to a global setting. The result is a contribution toward a transdenominational Pentecostal ecclesiology that has important implications for any attempt to construct a global Pentecostal ecclesiology.

The demand for information in a systematic way about ecology of target insect species of transgenic plants has increased in recent decades due to the growing interest in this new technology in pest management. Larval mobility in agricultural ecosystems when on occurrence of contamination of Bt crops, intentionally or unintentionally - has been subject of study by several researchers, however information about larval mobility in tropical conditions are still scarce. This scenario created opportunity for hypothesis testing on behavioural aspects of Spodoptera frugiperda (JE Smith) (Lepidoptera: Noctuidae) in landscapes with spatial-temporal co-occurence of Bt and non-Bt cotton plants. The main objective of the current research was to study the larval dispersal of the pest in field and laboratory conditions in order to insert computational modelling components to describe the evolution of resistance to Bt cotton. In the first chapter of this thesis, it is presented a general introduction. In the second one, we studied the feeding behaviour associated with larval dispersal of S. frugiperda genotypes and possible effects on spatial distribution of the resistant individuals in Bt and non-Bt cotton fields. We analyzed in the third chapter the consequences to resistance progress of the dispersal pattern of susceptible, Cry1F-resistant and heterozygous genotypes of S. frugiperda in pure and contaminated artificial landscapes. In the fourth chapter we assessed the impact of the dispersal by ballooning combined with walking dispersal on resistance evolution in conditions of plant mixture with non-Bt and Bt cotton plants in events with high and non-high dose. In the last chapter, we compared the movement dynamics of S. frugiperda genotypes between 28oC and 32oC, and with an individual-based model we analyzed the possibility if one of the genotypes could persist and would lead the other to the exclusion on refuge areas with non-Bt cotton plants. In a general way, faced on the larval dispersal of S. frugiperda genotypes, the results found here highlight the importance of implementation of strategies to avoid contamination through inadequate agronomic practices such as destruction of cotton plants after harvest, volunteer plant control, and seed saving after harvest. All information generated in this thesis could contribute in the optimization of regional resistance management within a concept of insect population control in wide areas. / A demanda por informações de forma sistematizada sobre ecologia de insetos-praga alvos de plantas transgênicas tem crescido nas últimas décadas devido ao proeminente interesse nesta tecnologia no manejo de pragas. A mobilidade larval em ecossistemas agrícolas quando na ocorrência de contaminação de plantas Bt, de forma intencional ou não intencional, tem sido assunto de estudo por diversos Pesquisadores, entretanto informações sobre a mobilidade larval em condições tropicais são ainda escassas. Este cenário criou oportunidades para testes de hipóteses em aspectos comportamentais de Spodoptera frugiperda (JE Smith) (Lepidoptera: Noctuidae) em paisagens com co-ocorrência espaço-temporal de plantas de algodão Bt e não Bt. O principal objetivo desta pesquisa foi estudar a dispersão larval da praga em condições de campo e de laboratório em ordem para inserir componentes de modelagem computacional para descrever a evolução da resistência ao algodão Bt. No primeiro capítulo desta tese, é apresentada uma introdução geral. No segundo capítulo, foi estudado o comportamento alimentar associado com a dispersão larval de genótipos de S. frugiperda e possíveis efeitos na distribuição espacial de indivíduos resistentes em campos de algodão Bt e não Bt. Foram analisadas no terceiro capítulo as consequências para o progresso da resistência do padrão de dispersão de genótipos suscetíveis, resistentes a Cry1F e heterozigotos de S. frugiperda em paisagens artificiais com pureza e com contaminação. No quarto capítulo, avaliou-se o impacto da dispersão por balonismo combinado dispersão por caminhamento na evolução da resistência em condições de mistura de plantas de algodão não Bt e algodão Bt em eventos com alta e baixa dose. No último capítulo, foi comparada a dinâmica de movimentação de genótipos de S. frugiperda entre as temperaturas de 28°C e 32°C, e com um modelo baseado no indivíduo analisou-se a possibilidade se um dos genótipos poderia persistir e levar o outro a exclusão em áreas de refúgio com plantas de algodão não Bt. Baseado na dispersão larval de genótipos de S. frugiperda, os resultados encontrados ressaltam a necessidade de implementação de estratégias para evitar contaminação por meio de práticas agronômicas inadequadas tais como destruição de plantas após a colheita, controle de plantas voluntárias, e o ato de se salvar as sementes após a colheita. Todas informações geradas nesta tese poderão contribuir para otimização de manejo da resistência regional dentro de um conceito de controle de insetos em grandes áreas.

Par leur fréquence d'horloge pouvant atteindre plusieurs dizaines de GHz et leur très faible dissipation, les circuits numériques supraconducteurs, fondés sur la logique à quantum de flux (RSFQ: Rapid Single-Flux Quantum), sont envisagés pour diverses applications spécifiques du fait de leurs performances exceptionnelles, très au delà de celles des filières électroniques classiques. Ces circuits RSFQ traitent l'information numérique sous forme d'impulsions de tension picoseconde avec une aire quantifiée de 2,07mV.ps, correspondant à un quantum de flux h/2e. L'électronique numérique supraconductrice ouvre ainsi la voie de l'électronique ultra-rapide en associant une large bande passante à une très faible dissipation.<br /><br />L'objectif de ce travail est d'étudier les interfaces optoélectroniques permettant de détecter et échantillonner les impulsions quantifiées résultant de la commutation des jonctions Josephson shuntées qui composent les circuits RSFQ. Nous avons développé une approche théorique et expérimentale de la sensibilité des photocommutateurs destinés à la détection d'impulsions RSFQ. Nous avons utilisé des photocommutateurs MSM (Métal-Semiconducteur-Métal) rapides de structure planaire à base d'Arséniure de Gallium épitaxié à basse température (AsGa-BT). Les caractéristiques physiques du matériau semi-conducteur telles que la résistance d'obscurité, la mobilité des porteurs libres et la durée de vie sont les paramètres clé pour obtenir des impulsions ultracourtes. La bonne résolution temporelle est donc assurée par les propriétés physiques du matériau. Un modèle basé sur un circuit hyperfréquence équivalent, a permis de prédire le comportement hyperfréquence du photocommutateur, éclairé ou non éclairé, lors du passage d'une impulsion RSFQ. De plus, ce modèle permet d'étudier l'influence des paramètres géométriques du photocommutateur sur la sensibilité de ce dernier. Nous avons déduit que le photocommutateur à gap à base d'AsGa-BT est bien adapté pour la détection des signaux subpicosecondes de faible amplitude.
