JWalk: a tool for lazy, systematic testing of java classes by design introspection and user interaction

Popular software testing tools, such as JUnit, allow frequent retesting of modified code; yet the manually created test scripts are often seriously incomplete. A unit-testing tool called JWalk has therefore been developed to address the need for systematic unit testing within the context of agile methods. The tool operates directly on the compiled code for Java classes and uses a new lazy method for inducing the changing design of a class on the fly. This is achieved partly through introspection, using Java’s reflection capability, and partly through interaction with the user, constructing and saving test oracles on the fly. Predictive rules reduce the number of oracle values that must be confirmed by the tester. Without human intervention, JWalk performs bounded exhaustive exploration of the class’s method protocols and may be directed to explore the space of algebraic constructions, or the intended design state-space of the tested class. With some human interaction, JWalk performs up to the equivalent of fully automated state-based testing, from a specification that was acquired incrementally

Transparent Dynamic reconfiguration for CORBA

Distributed systems with high availability requirements have to support some form of dynamic reconfiguration. This means that they must provide the ability to be maintained or upgraded without being taken off-line. Building a distributed system that allows dynamic reconfiguration is very intrusive to the overall design of the system, and generally requires special skills from both the client and server side application developers. There is an opportunity to provide support for dynamic reconfiguration at the object middleware level of distributed systems, and create a dynamic reconfiguration transparency to application developers. We propose a Dynamic Reconfiguration Service for CORBA that allows the reconfiguration of a running system with maximum transparency for both client and server side developers. We describe the architecture, a prototype implementation, and some preliminary test result

Brentano’s Concept of Intentional Inexistence

What Brentano meant by ‘intentional inexistence’ is explained, as is Brentano’s change of mind about this notion. It is only when we understand the metaphysical and methodological assumptions lying behind Brentano’s original doctrine that we can understand why we have a problem of intentionality in a way Brentano does not.Articl

RGBD Datasets: Past, Present and Future

Since the launch of the Microsoft Kinect, scores of RGBD datasets have been released. These have propelled advances in areas from reconstruction to gesture recognition. In this paper we explore the field, reviewing datasets across eight categories: semantics, object pose estimation, camera tracking, scene reconstruction, object tracking, human actions, faces and identification. By extracting relevant information in each category we help researchers to find appropriate data for their needs, and we consider which datasets have succeeded in driving computer vision forward and why. Finally, we examine the future of RGBD datasets. We identify key areas which are currently underexplored, and suggest that future directions may include synthetic data and dense reconstructions of static and dynamic scenes.Comment: 8 pages excluding references (CVPR style

Reflexivity in the research process: psychoanalytic observations

This paper highlights what psychoanalysis can add to discussions of reflexivity, by specifically describing how reflexivity is conceptualized and fostered on psychoanalytic observation methods courses at the Tavistock Clinic, London. It is demonstrated that this psychological form of reflexivity is relevant to empirical and conceptual work and shown that it shares interesting parallels with debates about reflexivity in social research methods, while also being able to contribute to discussions of what constitutes reflexivity and what kinds of methods course might facilitate it. Reflexivity is often discussed in relation to a researcher’s empirical work, but this paper argues that reflexivity is equally needed in relation to the academic context in which most research and learning takes place. This paper demonstrates how psychoanalytic approaches to learning stimulate a reflexive relation to empirical and conceptual work and it provides examples of reflexivity from a two year infant observation and a research project on romantic love (involving conceptual and biographical research)

The Potential Implications of Web-Based Marketing Communications for Consumers’ Implicit and Explicit Brand Attitudes: A Call for Research

Two developments in the last two decades frame the importance of Web-based marketing communications for firms. First is the phenomenal growth of the Internet as a viable commerce and communication option and second is the clear shift in attitude research toward recognizing the pervasive role of automatic processes in almost all the social psychological processes. Therefore, this article discusses the potential implications of Web-based marketing communications for consumers\u27 implicit and explicit attitudes. In doing so, first, this article reviews the emergence of research on implicit attitudes, distinguishes implicit attitudes from explicit attitudes, and discusses research on explicit and implicit attitudes relative to branding. Second, a brief discussion of marketing research on attitude is provided. Third, five empirically testable research propositions are developed and presented. Finally, given the potential implications for research and practice, the article concludes with a call for research
