Selection and prioritization of software requirements represents an area of interest in Search-Based Software Engineering (SBSE) and its main focus is finding and selecting a set of requirements that may be part of a software release. This paper uses a systematic review to investigate which SBSE approaches have been proposed to address software requirement selection and prioritization problems. The search strategy identified 30 articles in this area and they were analyzed for 18 previously established quality criteria. The results of this systematic review show which aspects of the requirements selection and prioritization problems were addressed by researchers, the methods approaches and search techniques currently adopted to address these problems, and the strengths and weaknesses of each of these techniques. The review provides a map showing the gaps and trends in the field, which can be useful to guide further research. © 2013 Springer-Verlag.

A case study on effectively identifying technical debt

17th International Conference on Evaluation and Assessment in Software Engineering, EASE 2013

Vetro, Antonio Shull, Forrest Seaman, Carolyn Fraunhofer USA Center for Experimental Software Engineering College Park United States Graduate Program in Systems and Computer UNIFACS Salvador Brazil Dept. of Control and Computer Engineering Politecnico di Torino Torino Italy Department of Information Systems UMBC Baltimore United States Elsevier Information Systems GmbH Frankfurt Germany

Context: The technical debt (TD) concept describes a tradeoff between short-term and long-term goals in software development. While it is highly useful as a metaphor, it has utility beyond the facilitation of discussion, to inspire a useful set of methods and tools that support the identification, measurement, monitoring, management, and payment of TD. Objective: This study focuses on the identification of TD. We evaluate human elicitation of TD and compare it to automated identification. Method: We asked a development team to identify TD items in artifacts from a software project on which they were working. We provided the participants with a TD template and a short questionnaire. In addition, we also collected the output of three tools to automatically identify TD and compared it to the results of human elicitation. Results: There is little overlap between the TD reported by different developers, so aggregation, rather than consensus, is an appropriate way to combine TD reported by multiple developers. The tools used are especially useful for identifying defect debt but cannot help in identifying many other types of debt, so involving humans in the identification process is necessary. Conclusion: We have conducted a case study that focuses on the practical identification of TD, one area that could be facilitated by tools and techniques. It contributes to the TD landscape, which depicts an understanding of relationships between different types of debt and how they are best discovered. Copyright 2013 ACM.

We identified and organized a number of statements about technical debt (TD Folklore list) expressed by practitioners in online websites, blogs and published papers. We chose 14 statements and we evaluated them through two surveys (37 practitioners answered the questionnaires), ranking them by agreement and consensus. The statements most agreed with show that TD is an important factor in software project management and not simply another term for 'bad code'. This study will help the research community in identifying folklore that can be translated into research questions to be investigated, thus targeting attempts to provide a scientific basis for TD management. © 2013 IEEE.

The firefly algorithm (FA) is a new population-based metaheuristic bioinspired on the behavior of the flashing characteristics of fireflies. As a population-based algorithm, the FA suffers from large execution times specifically for embedded optimization problems with computational limitations. For reducing execution times we propose a hardware parallel architecture of the FA algorithm that facilitates the implementation in Field programmable Gate Arrays (FPGAs). In addition, this work proposes the application of the opposition-based learning (OBL) approach to the FA algorithm. The respective hardware implementation (HPOFA) was mapped into a Virtex5 FPGA device and numerical experiments using four well-known benchmark problems demonstrate that the opposition-based approach allows the FA algorithm to improve its functionality, preserving the swarm diversity and avoiding the premature convergence problem. Synthesis results point out that the HPOFA architecture is effectively mapped in hardware and is suitable for embedded applications. © 2013 IEEE.

Using Social Network Analysis to Promote Schoolwide Instructional Innovation: A Case Study

Journal of School Leadership 2014年第1期24卷 114 - 145页

作者： Rebecca H. Woodland Shannon Barry Katrina Crotts Roohr Educational leadership at the University of Massachusetts Amherst. She is a former public school teacher and administrator and was director of secondary teacher education at the University of Vermont. She also directs the Teacher Collaboration and Instructional Improvement Partnership a school–university partnership that creates systems for tiered models of intervention and the diffusion of instructional innovation. School psychology program and a graduate research assistant in the Department of Educational Policy Research and Administration at the University of Massachusetts Amherst. Her research interests include early academic and behavioral intervention and prevention efforts social–emotional learning and positive behavior support. Psychometric methods educational statistics and research methods concentration at the University of Massachusetts Amherst. Her research interests include test accommodations for English-language learners and students with disabilities test validity and fairness computer-based testing and applications of item response theory.

Social network analysis (SNA), a methodological approach that enables the mathematical examination of interprofessional relationships, can be an important tool for understanding and leveraging the social relationships that support and restrain instructional innovation and the quality and pace of school reform initiatives. In this article, we explicate the conceptual underpinnings of SNA and summarize how it has been used in a range of preK–12 educational evaluation contexts. A school-based case study is presented in which school leaders examined formal and advice-seeking networks among teachers, staff, and administrators and used the findings to reduce teacher isolationism, promote efficient communication, and increase system capacity for instructional innovation. Challenges associated with SNA for educational evaluation and school improvement are also discussed.

2012 5th International Workshop on Exception Handling, WEH 2012

The context-awareness is a central aspect in the design of pervasive systems, characterizing their ability to adapt its structure and behavior. The context-aware exception handling (CAEH) is an existing approach employed to design exception handling in pervasive systems. In this approach, the context is used to define, detect, propagate, and handle exceptions. CAEH is a complex and error prone activity, needing designers' insights and domain expertise to identify and characterize contextual exceptions. However, despite the existence of formal methods to analyze the adaptive behavior of pervasive systems, such methods lack specific support to specify the CAEH behavior. In this paper, we propose a formal model to reason about the CAEH behavior. It comprises an extension of the Kripke Structure to model the context evolution of a pervasive system and a transformation function that derivates the CAEH control flow from that proposed structure. © 2012 IEEE.
