“Don’t Fear the Literature Review!” A Review of Literature Review Teaching Tools

The literature review is a difficult aspect of research methods courses. The act of artfully weaving together content from an array of scholarly sources is a challenge to teach. This presentation introduces faculty members to literature review teaching strategies, including multiple pathways to better understand a topic\u27s pertinent literature

Distributed aspect-oriented service composition for business compliance governance with public service processes

Service-Oriented Architecture (SOA) offers a technical foundation for Enterprise Application Integration and business collaboration through service-based business components. With increasing process outsourcing and cloud computing, enterprises need process-level integration and collaboration (process-oriented) to quickly launch new business processes for new customers and products. However, business processes that cross organisations’ compliance regulation boundaries are still unaddressed. We introduce a distributed aspect-oriented service composition approach, which enables multiple process clients hot-plugging their business compliance models (business rules, fault handling policy, and execution monitor) to BPEL business processes

An ontology of agile aspect oriented software development

Both agile methods and aspect oriented programming (AOP) have emerged in recent years as new paradigms in software development. Both promise to free the process of building software systems from some of the constraints of more traditional approaches. As a software engineering approach on the one hand, and a software development tool on the other, there is the potential for them to be used in conjunction. However, thus far, there has been little interplay between the two. Nevertheless, there is some evidence that there may be untapped synergies that may be exploited, if the appropriate approach is taken to integrating AOP with agile methods. This paper takes an ontological approach to supporting this integration, proposing ontology enabled development based on an analysis of existing ontologies of aspect oriented programming, a proposed ontology of agile methods, and a derived ontology of agile aspect oriented development

Context constraint integration and validation in dynamic web service compositions

System architectures that cross organisational boundaries are usually implemented based on Web service technologies due to their inherent interoperability benets. With increasing exibility requirements, such as on-demand service provision, a dynamic approach to service architecture focussing on composition at runtime is needed. The possibility of technical faults, but also violations of functional and semantic constraints require a comprehensive notion of context that captures composition-relevant aspects. Context-aware techniques are consequently required to support constraint validation for dynamic service composition. We present techniques to respond to problems occurring during the execution of dynamically composed Web services implemented in WS-BPEL. A notion of context { covering physical and contractual faults and violations { is used to safeguard composed service executions dynamically. Our aim is to present an architectural framework from an application-oriented perspective, addressing practical considerations of a technical framework

A consistency framework for dynamic reconfiguration in AO-middleware architectures

Aspect-oriented (AO) middleware is a promising technology for the realisation of dynamic reconfiguration in distributed systems. Similar to other dynamic reconfiguration approaches, AO-middleware based reconfiguration requires that the consistency of the system is maintained across reconfigurations. AO middleware based reconfiguration is an ongoing research topic and several consistency approaches have been proposed. However, most of these approaches tend to be targeted at specific narrow contexts, whereas for heterogeneous distributed systems it is crucial to cover a wide range of operating conditions. In this paper we address this problem by exploring a flexible, framework-based consistency management approach that cover a wide range of operating conditions ensuring distributed dynamic reconfiguration in a consistent manner for AO-middleware architectures

Towards an Expressive and Scalable Framework for expressing Join Point Models

Join point models are one of the key features in aspectoriented programming languages and tools. They provide\ud software engineers means to pinpoint the exact locations in programs (join points) to weave in advices. Our experience in modularizing concerns in a large embedded system showed that existing join point models and their underlying program representations are not expressive enough. This prevents the selection of some join points of our interest. In this paper, we motivate the need for more fine-grained join point models within more expressive source code representations. We propose a new program representation called a program graph, over which more fine-grained join point models can be defined. In addition, we present a simple language to manipulate program graphs to perform source code transformations. This language thus can be used for specifying complex weaving algorithms over program graphs

Tangled Web of Associational Life: Urban Governance and the Politics of Popular Livelihoods in Nigeria

Drawing on case studies of informal enterprise associations in Christian and Muslim parts of Nigeria, this paper explores the differing ways in which networks of ethnicity, class and religion are used to forge links between dynamic informal organizational systems and formal institutions of government
