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

Is the internet good for our environment?

Reports on various studies of the net environmental impact of the internet. Considers such aspects as the energy use of computers and the avoidance of personal transport by the use of internet services

The early years of Sequoia and Kings Canyon Science: Building a research program

This paper provides a history of the development of the scientific research program at Sequoia and Kings Canyon National Parks (SEKI) during the period 1968–1994 from the perspective of one of the scientists involved. The years following the 1968 hiring of Bruce Kilgore as the first park-based research scientist at SEKI saw the growth of a research program that included three permanent research-grade scientists and their support staff.  This nucleus was successful in attracting both outside funding and leading university and government scientists to work on issues of importance to the parks and to society at large, topics that included fire ecology and management, black bears, wilderness impacts, acid deposition, and climate change. During this time the SEKI scientists’ role expanded from one focused primarily on the personal research on issues of immediate importance to the park, to increasing responsibilities for marketing and coordinating a growing program of collaborative research that also addressed regional and national priorities. This, in turn, required that the park scientists increasingly become generalists, able to converse in a number of scientific disciplines as well as communicate with non-scientists. Finally, keys to success and lessons learned are discussed

Globule transitions of a single homopolymer: a Wang-Landau Monte Carlo study

The temperature-independent Wang-Landau Monte Carlo approach is implemented for an off-lattice model of flexible homopolymers and applied to the coil-globule and solidification transitions based on chain sizes up to N=300. An intermediate transformation from low-density liquid globule to high-density liquid globule is suggested. A scheme for identifying polymer structures representative of particular temperatures in the course of the simulation is presented and applied to illustrate intermediate states in the coil-globule transition. Transition temperatures are calculated and used to obtain a theta point of at least Θ=1.96, distinctly higher than the solid-liquid transition temperature TM=1.26

Impact of European Water Framework Directive Article 7 on Drinking Water Directive compliance for pesticides: challenges of a prevention-led approach

Article 7 of the European Water Framework Directive (WFD) promotes a prevention-led approach to European Drinking Water Directive (DWD) compliance for those parameters that derive from anthropogenic influences on raw water quality. However, the efficacy of pollution prevention interventions is currently uncertain and likely to be variable, which makes absolute compliance with the drinking water standard a significant challenge. Member State governments, the WFD competent authority, the DWD competent authority, water suppliers and agriculture are all affected by and have a different perspective on the nature of this challenge. This paper presents a discussion of these perspectives applicable to stakeholders in all European Member States; the analysis is supported with examples from England and Wales. Improved understanding of the challenges faced by each group is needed if these groups are to achieve the shared goals of WFD Article 7 compliance and DWD compliance without a disproportionately negative impact on agricultural productivity. In addition, the European Commission needs to be aware of and address a potential incompatibility between WFD Article 7 and the DWD. With this in mind, targeted recommendations for action are presented for each stakeholder group

Bridging digital divides in the learning process: challenges and implications of integrating ICTs

Abstract: This paper investigates an initiative by a New Zealand School to integrate one-to-one ICTs into the learning process, called \u27Bring your own device\u27 (BYOD). Prior to embarking on the BYOD initiative, similar past initiatives have been studied and some persistent issues have been identified. Before starting with the detailed investigation of BYOD, a preliminary analysis of the public response data from different sources has also been conducted. From the past initiatives and preliminary analysis of public responses, we have been able to form general research questions for the study. A socio-cultural ecological approach to mobile learning has been considered appropriate as a means of analysis for this study. Authors: Janak Adhikari, Doctoral Student; Dr. David Parsons, Associate Professor and Dr. Anuradha Mathrani, Lecturer, in the department of Information Technology, Massey University Auckland. This paper was presented at mLearn 2012 Mobile and Contextual Learning, Helsinki, Finland, October 16 -18, 2012 and published in the Proceedings of the 11th International Conference on Mobile and Contextual Learning .  &nbsp

Evolving Architectural Patterns For Web Applications

Web application architectural component relationships have evolved over the last decade or so to the point where they have become well established both as common design patterns and embedded in software frameworks. However with the increasing adoption of Web 2.0 technologies and Ajax based web applications, new patterns are starting to emerge. These patterns have yet to become well established in the literature, though a number of new frameworks are beginning to appear. In this paper we review the core patterns of traditional web application architectures, as described in the literature. We then move on to collect some new patterns that have begun to emerge and integrate them into a larger architectural view of how contemporary web applications are evolving. Where it is necessary to illustrate these patterns within a specific web technology, we use components from the Java Enterprise Edition

Is a Higher Calling Enough? Incentive Compensation in the Church (CRI 2009-011)

We study the compensation and productivity of more than 2,000 Methodist ministers in a 43-year panel data set. The church appears to use pay-for-performance incentives for its clergy, as their compensation follows a sharing rule by which pastors receive approximately 3% of the incremental revenue from membership increases. Ministers receive the strongest rewards for attracting new parishioners who switch from other congregations within their denomination. Monetary incentives are weaker in settings where ministers have less control over their measured performance
