Ownership, experience and defects

Foyzur Rahman, Premkumar Devanbu
2011 Proceeding of the 33rd international conference on Software engineering - ICSE '11  
This paper considers the impact of code ownership and developer experience on software quality. In a large project, a file might be entirely owned by a single developer, or worked on by many.  ...  Prior research considered this phenomenon at the level of modules or files, and thus does not tease apart and study the effect of contributions of different developers to each module or file.  ...  Acknowledgments We thank A. Bachmann and A. Bernstein for the bug linking data.  ...

How Well Do Change Sequences Predict Defects? Sequence Learning from Software Changes

Ming Wen, Rongxin Wu, S.C. Cheung
2018 IEEE Transactions on Software Engineering  
In this paper, we propose a novel approach called FENCES, which extracts six types of change sequences covering different aspects of software changes via fine-grained change analysis.  ...  In terms of AUC, FENCES achieves an average value of 0.892, and the improvements over baselines vary from 4.2% to 16.1%.  ...  Specifically, we design a type of sequence that tracks all the semantic information of each change via fine-grained change analysis.  ...

Slice-Based Cognitive Complexity Metrics for Defect Prediction

Basma S. Alqadi, Jonathan I. Maletic
2020 2020 IEEE 27th International Conference on Software Analysis, Evolution and Reengineering (SANER)  
A similar study by Rahman and Devanbu examined the effects of ownership and experience on quality in several open-source projects, using a fine-grained level of analysis based on fix-inducing code-fragments  ...  Ownership and Authorship Metrics Ownership and authorship were discussed by Bird et al. who finding is that QA should be focused on code files touched by less experienced developers and that a developer's  ...

Bug prediction based on fine-grained module histories

Hideaki Hata, Osamu Mizuno, Tohru Kikuno
2012 2012 34th International Conference on Software Engineering (ICSE)  
Many studies have reported the effectiveness of these historical metrics. For prediction levels, most studies have targeted package and file levels.  ...  Prediction on a fine-grained level, which represents the method level, is required because there may be interesting results compared to coarse-grained (package and file levels) prediction.  ...  Rahman and Devanbu examined the effects of ownership and experience on quality [13] . They conducted a finegrained study about authorship and ownership of code fragments.  ...

git2net - Mining Time-Stamped Co-Editing Networks from Large git Repositories [article]

Christoph Gote, Ingo Scholtes, Frank Schweitzer
2019 arXiv   pre-print
Addressing this issue, we introduce git2net, a scalable python software that facilitates the extraction of fine-grained co-editing networks in large git repositories.  ...  Most of the studied networks are based on the co-authorship of software artefacts defined at the level of files, modules, or packages.  ...  We specifically demonstrate (A) the construction of different static network projections capturing co-editing, co-authorship, and code-ownership relations, (B) a comparative study of finegrained co-editing  ...

Analysing Time-Stamped Co-Editing Networks in Software Development Teams using git2net

Tolerating and Managing Failure: An Organizational Perspective on Customer Reacquisition Management

Arnd Vomberg, Christian Homburg, Olivia Gwinner
2020 Journal of Marketing

Voice disguise by mimicry: deriving statistical articulometric evidence to evaluate claimed impersonation

Rita Singh, Abelino Jiménez, Anders Øland
2017 IET Biometrics  
In this paper we address the problem of disproving the denial of voice ownership from an articulatory-phonetic perspective, and propose a hypothesis testing framework that may be used to solve it.  ...  Voice evidence from these crimes is analyzed to both detect impersonation, and match the impersonated voice to the natural voice of the speaker to prove its correct ownership.  ...  Since such a denial is generally a refutation of identity matches obtained through evaluation of large-grained statistical characteristics, we must focus on fine-detail features to reject the denial.  ...

Does Reviewer Recommendation Help Developers?

, influence of recommendations on human choices, and their effect on user experience.  ...  We confirm this finding with a larger study at another company. The confirmation of this finding brings up a case for more user-centric approaches to designing and evaluating the recommenders.  ...  Thus, we cannot claim that no feedback is present, but only that it is too subtle to be detected without a controlled experiment; setting up such experiment would require a lot of resources.  ...

Should I Bug You? Identifying Domain Experts in Software Projects Using Code Complexity Metrics

Ralf Teusner, Christoph Matthies, Philipp Giese
2017 2017 IEEE International Conference on Software Quality, Reliability and Security (QRS)  
Furthermore, teams can detect those parts of the software for which currently no, or only few experts exist and take preventive actions to keep the collective code knowledge and ownership high.  ...  We employed the developed approach at a medium-sized company. The results were evaluated with a survey, comparing the perceived and the computed expertise of developers.  ...  Metrics are computed on a file basis, instead of directly at package or component level, as this allows more fine-grained analyses and supports applying weighting operations earlier in the calculation.  ...

Against Endowment Theory: Experimental Economics and Legal Scholarship

Gregory Klass, Kathryn Zeiler
2013 Social Science Research Network  
Endowment theory holds the mere ownership of a thing causes people to assign greater value to it than they otherwise would.  ...  The theory entered legal scholarship in the early 1990s and quickly eclipsed other accounts of how ownership affects valuation.  ...  But that answer is not fine grained enough to explain the data or predict when the effect will appear.  ...

Schizophrenia as a self-disorder due to perceptual incoherence

L. Postmes, H.N. Sno, S. Goedhart, J. van der Stel, H.D. Heering, L. de Haan
2014 Schizophrenia Research  
From a developmental perspective multisensory integration is considered to be crucial for normal self-experience. An impairment of multisensory integration is called 'perceptual incoherence'.  ...  We theorize that perceptual incoherence may evoke incoherent self-experiences including depersonalization, ambivalence, diminished sense of agency, and 'loosening of associations' between thoughts, feelings  ...  DSM fulfilled a need for objectivity and scientific verification. Against the grain, phenomenological studies continued in Europe (Huber, 1995; Klosterkötter et al., 1997; Parnas, 1999) .  ...
