A recent trend in software industry is to provide enterprise applications in the cloud that are accessible everywhere and on any device. As the market is highly competitive, customer orientation plays an important role. Companies therefore start providing applications as a service, which are directly configurable by customers in an online self-service portal. However, customer configurations are usually deployed in separated application instances. Thus, each instance is provisioned manually and must be maintained separately. Due to the induced redundancy in software and hardware components, resources are not optimally utilized. A multi-tenant aware application architecture eliminates redundancy, as a single application instance serves multiple customers renting the application. The combination of a configuration self-service portal with a multi-tenant aware application architecture allows serving customers just-in-time by automating the deployment process. Furthermore, self-service portals improve application scalability in terms of functionality, as customers can adapt application configurations on themselves according to their changing demands. However, the configurability of current multi-tenant aware applications is rather limited. Solutions implementing variability are mainly developed for a single business case and cannot be directly transferred to other application scenarios. The goal of this thesis is to provide a generic framework for handling application variability, automating configuration and reconfiguration processes essential for self-service portals, while exploiting the advantages of multi-tenancy. A promising solution to achieve this goal is the application of software product line methods. In software product line research, feature models are in wide use to express variability of software intense systems on an abstract level, as features are a common notion in software engineering and prominent in matching customer requirements against product functionality. This thesis introduces a framework for feature-based configuration management of reconfigurable cloud applications. The contribution is three-fold. First, a development strategy for flexible multi-tenant aware applications is proposed, capable of integrating customer configurations at application runtime. Second, a generic method for defining concern-specific configuration perspectives is contributed. Perspectives can be tailored for certain application scopes and facilitate the handling of numerous configuration options. Third, a novel method is proposed to model and automate structured configuration processes that adapt to varying stakeholders and reduce configuration redundancies. Therefore, configuration processes are modeled as workflows and adapted by applying rewrite rules triggered by stakeholder events. The applicability of the proposed concepts is evaluated in different case studies in the industrial and academic context. Summarizing, the introduced framework for feature-based configuration management is a foundation for automating configuration and reconfiguration processes of multi-tenant aware cloud applications, while enabling application scalability in terms of functionality.

In Chapter 1 different phases of the application of exegetical methods with regard to texts in the New Testament were identified. Each phase provided a different perspective in response to questions about the contextuality of the New Testament. From the overview it became clear that the investigation of the historical background had received some attention, but it had not been as effectively utilized in the hermeneutical process as it could be, and had not been taken seriously enough. In Chapter 2, the place and function of the historical context or background of the New Testament in historical criticism, literary criticism and social scientific methods of exegesis were evaluated. Historical criticism often focuses on the different parts (forms) of the text, but does not consider the text as a whole to the degree required. Literary criticism focuses on the text as a whole. The Gospels are regarded as narrative texts. Narratology foregrounds the spatial aspects or topology of the Gospels. Socio-historical research on the world of the text, contributes to the study of the background of the New Testament. To enhance the progress already made, historical criticism and literary criticism can be supplemented by applying selected social scientific models. The use of such models makes it possible for socio-historical data to be systematized in a holistic interpretive framework. The use of social scientific models can bridge the historical distance between the text and its readers to avoid fallacies based on anachronism and ethnocentrism. A social scientific approach provides a holistic frame of reference for the interpretation of Biblical texts. However the approach may not pay enough attention to the topological or spacial aspects of the Gospel of Matthew. The model of advanced agrarian society and the pre-industrial city have not yet been applied effectively to the Gospel of Matthew. The current study fills this gap. In the study the model in terms of which an advanced agrarian society can be descibed, is used as a broad frame of reference within which the place and function of the Biblical jubilee can be studied. This diachronic overview of the research on the Biblical jubilee (Chapter 3) shows that no such study has as yet been undertaken with regard to the Biblical jubilee. Ancient economy developed from a simplistic agrarian society to an advanced agrarian society. The Roman Empire was the result of a long evolutionary process. Land was the primary economic resource in a self-sufficient society. The aim of the current research was to show that the socio-economic background of the first century forms the context within which the land and jubilee can be understood. The socio-economic background can be interpreted within a holistic perspective of first-century Mediterranean society. The social scientific model of advanced agrarian society includes four factors (family institutions, pre-industrial city, land tenancy and social stratification) that all influenced the land and economy of the first-century Mediterranean world. In Chapter 6, homomorphic models were used to simplify important and representative aspects of complex social structures, behaviour and relations. These models were used for the study of the political, economic and social systems of an empire or government. The current study used the social scientific model of advanced agrarian society as frame of reference for the interpretation of the place and function of the Biblical jubilee in the Gospel of Matthew. / Dissertation (DD(New Testament Studies))--University of Pretoria, 2001. / New Testament Studies / unrestricted

This thesis examined the evolution and transition of agrarian labour relations in the aftermath of Zimbabwe‘s radical land redistribution, which reconfigured the agrarian structure in terms of landholdings, production practices and labour markets from 2000. Despite the importance of agrarian labour as source of livelihood for the largely countryside based population, insufficient academic attention has been paid to its evolution following the land reforms. Specifically to the mobilisation, organisation and utilisation of wage and non-wage labour against background of the changed land ownership patterns, agrarian policies and macro-economic conditions. Historical-structural approaches rooted in Marxist Political Economy informed the analysis of the new agrarian labour relations since in former Settler colonies such as Zimbabwe these were based were based on a historical context of specific land-labour utilisation relations created by land dispossession and discriminatory agrarian policies during the colonial and immediate independence period. Beyond this, gender issues, intra-household relations, kinship, citizenship and the agency of the workers were taken into account to understand the trajectory of labour relations. Detailed quantitative and qualitative empirical research in Goromonzi and Kwekwe districts, as well as from other sources demonstrated that a new agrarian labour regime had evolved to replace the predominant wage labour in former large-scale commercial farms. There has been a growth in the use of self-employed family farm labour alongside the differentiated use of wage labour in farming and other non-farm activities. Inequitable gender and generational tendencies were evident in the new agrarian labour regime. The new labour relations are marked by the exploitation of farm workers through wages that are below the cost of social reproduction, insecure forms of employment and poor working conditions. While their individual and collective worker agency is yet to reverse their poor socio-economic conditions. Various policy interventions to protect their land and labour rights are thus required. The study shed light on the the conceptual understanding of agrarian labour relations in former Settler economies, including the role of land reforms in the development of employment, and how the peasantry with enlarged land access are reconstituted through repeasantisation and semi-proletarianisation processes. / Public Administration and Management / D.
