How often have you been able to implement an algorithm as it is described in a paper? And when you did, were you con�dent that you had exactly the same parameter values and results as the authors of the paper? All too often, articles do not describe all the details of an algorithm and thus prohibit an implementation by someone else. In this paper, we describe our experience with reproducible research, a paradigm to allow other people to reproduce with minimal effort the results we have obtained. We discuss both the reproducibility of data and algorithms, and give examples for each of them. The effort required to make research reproducible is compensated by a higher visibility and impact of the results. Index Terms — reproducible research, publishing, source code, open source software 1.

its responsibilities towards the users of social media. The retail businesses extensively use the social media and are engaging with the various users of social networks. The paper also analyses the use of social media and its opportunities in the global retail world. The paper finally draws

Abstract: Spacetime foam manifests itself in a variety of ways. It has some attributes of a turbulent fluid. It is the source of the holographic principle. Cosmologically it may play a role in explaining why the energy density has the critical value, why dark energy/matter exists, and why the effective dynamical cosmological constant has the value as observed. Astrophysically the physics of spacetime foam helps to elucidate why the critical acceleration in modified Newtonian dynam-ics has the observed value; and it provides a possible connection be-tween global physics and local galactic dynamics involving the phe-nomenon of flat rotation curves of galaxies and the observed Tully-Fisher relation. Spacetime foam physics also sheds light on nonlocal gravitational dynamics.

that describe the images. The interface makes use of hierarchical faceted metadata and dynamically generated query previews. A usability study, conducted with 32 art history students exploring a collection of 35,000 fine arts images, compares this approach to a standard image search interface. Despite

Oriented filters are useful in many early vision and image processing tasks. One often needs to apply the same filter, rotated to different angles under adaptive control, or wishes to calculate the filter response at various orientations. We present an efficient architecture to synthesize filters

in current computer technology. Ontologies provide a shared and common understanding of a domain that can be communicated between people and application systems. Therefore, they may play a major role in supporting information exchange processes in various areas. This book discusses the role ontologies

to experience discomfort has had a long history in psychology. In social psychology, for example, various early theories proposed a relation between discomfort and specific kinds of "inconsistency " among a person's beliefs (e.g., Abelson

Scholars of the theory of the firm have begun to emphasize the sources and conditions of what has been described a s "the organizational advantage, " rather than focus on the causes and consequences of market failure. Typically, researchers see such organizational advantage a s accruing from the particular capabilities organizations have for creating and sharing knowledge. In this article we seek to contribute to this body 01 work by developing the following arguments: (1) social capital facilitates the creation of new intellectual capital. (2) organizations. a s institutional settings. a re conducive to the development of high levels of social capital. and (3) it is because of their more dense social capital that firms. within certain limits. have a n advantage over markets in creating and sharing intellectual capital. We present a model that incorporates this overall argument in the form of a series of hypothesized relation-ships between different dimensions of social capital and the main mechanisms and processes necessary for the creation of intellectual capital. Kogut and Zander recently have proposed "that a firm be understood a s a social commu-nity specializing in the speed and efficiency in the creation and transfer of knowledge " (1996: 503). This is an important and relatively new perspective on the theory of the firm currently being formalized through the ongoing work of
