标题： Software development practices in academia: a case study comparison

摘要： 学术软件开发实践通常与商业开发环境中的实践不同，然而迄今为止对学术界软件开发实践的评估研究仍然有限。 在这里，我们展示了一个案例研究，研究了在九年期间四个开源科学代码的软件开发实践，描述了各自开发团队的演变、他们的科学生产力，以及随着团队规模变化而采用（或停止采用）的具体软件工程实践。 我们表明，开发团队的临时性质导致采用了不同的开发策略。 我们将出版物产出的度量与累计开发人员数量相关联，并发现对于所考虑的项目， expended 开发努力的回报时间尺度大约为三年。 我们讨论了这些发现对评估研究软件开发绩效的影响，以及对任何计算导向的科学项目的普遍意义。 显示英文摘要

摘要： Academic software development practices often differ from those of commercial development settings, yet only limited research has been conducted on assessing software development practises in academia. Here we present a case study of software development practices in four open-source scientific codes over a period of nine years, characterizing the evolution of their respective development teams, their scientific productivity, and the adoption (or discontinuation) of specific software engineering practises as the team size changes. We show that the transient nature of the development team results in the adoption of different development strategies. We relate measures of publication output to accumulated numbers of developers and find that for the projects considered the time-scale for returns on expended development effort is approximately three years. We discuss the implications of our findings for evaluating the performance of research software development, and in general any computationally oriented scientific project.
