Getting to the Source of Ethical Issues

Research with open source software (OSS) raises the same ethical issues as other disciplines in which publicly released materials are the objects of study, and the creators of those materials are still living. These disciplines are literary and artistic criticism and public policy research. As El-Emam (this issue) mentioned there are also similarities to research employing internet newsgroup posts as data.Les recherches effectu\ue9es dans le domaine des logiciels \ue0 code source libre soul\ue8vent les m\ueames probl\ue8mes d'\ue9thique que dans les autres disciplines, o\uf9 des documents diffus\ue9s dans le public font l'objet d'\ue9tudes, alors que leurs auteurs sont toujours vivants. La critique litt\ue9raire, la critique artistique et les recherches sur les politiques gouvernementales constituent de telles disciplines. Comme le mentionne \ue9galement M. El Emam (dans ce num\ue9ro), il existe \ue9galement des similitudes avec les recherches qui font appel \ue0 des documents diffus\ue9s par des groupes de nouvelles sur l'Internet.Peer reviewed: YesNRC publication: Ye

Ethical Issues in Empirical Studies of Software Engineering

The popularity of empirical methods in software engineering research is on the rise. Surveys, experiments, metrics, case studies, and field studies are examples of empirical methods used to investigate both software engineering processes and products. The increased application of empirical methods has also brought about an increase in discussions about adapting these methods to the peculiarities of software engineering. In contrast, the ethical issues raised by empirical methods have received little, if any, attention in the software engineering literature. This article is intended to introduce the ethical issues raised by empirical research to the software engineering research community, and to stimulate discussion of how best to deal with these ethical issues. Through a review of the ethical codes of several fields that commonly employ humans and artifacts as research subjects, we have identified major ethical issues relevant to empirical studies of software engineering. These issues are illustrated with real empirical studies of software engineering

Comparing the correlation length of grain markets in China and France

In economics comparative analysis plays the same role as experimental research in physics. In this paper we closely examine several methodological problems related to comparative analysis by investigating the specific example of grain markets in China and France respectively. This enables us to answer a question in economic history which has so far remained pending, namely whether or not market integration progressed in the 18th century. In economics as in physics, before being accepted any new result has to be checked and re-checked by different researchers. This is what we call the replication and comparison procedures. We show how these procedures should (and can) be implemented.Comment: 16 pages, 7 figures, to appear in International Journal of Modern Physics

The economics of garbage collection

This paper argues that economic theory can improve our understanding of memory management. We introduce the allocation curve, as an analogue of the demand curve from microeconomics. An allocation curve for a program characterises how the amount of garbage collection activity required during its execution varies in relation to the heap size associated with that program. The standard treatment of microeconomic demand curves (shifts and elasticity) can be applied directly and intuitively to our new allocation curves. As an application of this new theory, we show how allocation elasticity can be used to control the heap growth rate for variable sized heaps in Jikes RVM

Maximizing the information gain of a single ion microscope using bayes experimental design

We show nanoscopic transmission microscopy, using a deterministic single particle source and compare the resulting images in terms of signal-to-noise ratio, with those of conventional Poissonian sources. Our source is realized by deterministic extraction of laser-cooled calcium ions from a Paul trap. Gating by the extraction event allows for the suppression of detector dark counts by six orders of magnitude. Using the Bayes experimental design method, the deterministic characteristics of this source are harnessed to maximize information gain, when imaging structures with a parametrizable transmission function. We demonstrate such optimized imaging by determining parameter values of one and two dimensional transmissive structures.Comment: 8 pages, 7 figures, From SPIE Conference Volume 9900, Quantum Optics, J\"urgen Stuhler; Andrew J.
