The structure of a ferrofluid under the influence of an external magnetic field is expected to become anisotropic due to the alignment of the dipoles into the direction of the external field, and subsequently to the formation of particle chains due to the attractive head to tail orientations of the ferrofluid particles. Knowledge about the structure of a colloidal ferrofluid can be inferred from scattering data via the measurement of structure factors. We have used molecular-dynamics simulations to investigate the structure of both monodispersed and polydispersed ferrofluids. The results for the isotropic structure factor for monodispersed samples are similar to previous data by Camp and Patey that were obtained using an alternative Monte Carlo simulation technique, but in a different parameter region. Here we look in addition at bidispersed samples and compute the anisotropic structure factor by projecting the q vector onto the XY and XZ planes separately, when the magnetic field was applied along the z axis. We observe that the XY- plane structure factor as well as the pair distribution functions are quite different from those obtained for the XZ plane. Further, the two- dimensional structure factor patterns are investigated for both monodispersed and bidispersed samples under different conditions. In addition, we look at the scaling exponents of structure factors. Our results should be of value to interpret scattering data on ferrofluids obtained under the influence of an external field.

This chapter discusses the pedagogic and scholarly priorities that informed Heyne’s commentaries on Tibullus (1755), Virgil (1767-75) and Homer (1802), as well as their initial critical reception. Like those of his teachers, Gesner and Ernesti, Heyne’s works eschew detailed textual scholarship in favour of aesthetic and historicizing appreciation of literary works as wholes. Their formal innovations – most notably the relegation of advanced philological discussions to endnotes and the inclusion of excursuses on significant historical and cultural questions – are an attempt to tailor a traditional format to the demands of an Enlightened age and the cultural-historical interests of the new Altertumswissenschaft. The chapter discusses their contrasting critical receptions in order to raise questions about the viability of Heyne’s endeavours to make a traditional medium fit new concerns.

Theophilus (Gottlieb) Siegfried Bayer (1694-1738) is usually credited as the first person in modern times to address the history of the Greeks in Bactria in a serious way. Bayer’s Historia Regni Graecorum Bactriani, brings together numismatic and historical research. He describes two Graeco-Bactrian coins which he was able to examine first hand, and collects and comments upon the Classical historical sources on the Greek kingdoms of Bactria and India. It was published in St. Petersburg in 1738, where Bayer, a German, held an academic position. In this short article, I am interested in two questions surrounding the Historia Regni Graecorum Bactriani. First (and relatively briefly), how Bayer conducted his research without first hand access to source material and without himself travelling in Bactria – or indeed further east than St. Petersburg. Secondly, the way in which Bayer’s scholarship was received by some of his contemporaries and by later writers, outside the field of Bactrian studies.

Winckelmann's writings hold an interest for modern classical studies which is not restricted to the subfield of classical archaeology. Considered in terms of methodology, his writings dramatise problems and questions which attend any attempt to provide a comprehensive account of ancient culture and society. The Geschichte der Kunst des Alterthums provided an influential model of what such a reconstruction might look like in a period when classical philology was undergoing a significant reconfiguration as „Alterthums-Wissenschaft" at the hands of scholars such as Christian Gottlob Heyne and Friedrich August Wolf. Investigation of their critical responses to Winckelmann’s works aims to contribute to understanding both of the early reception of his works and of questions which are still relevant today. Im Rahmen der modernen Altertumswissenschaften kommt den Werken Winckelmanns eine Bedeutung zu, die nicht auf den Bereich der Klassischen Archäologie beschränkt ist. Methodologisch betrachtet, dramatisieren seine Schriften Probleme und Fragen, die jedem Versuch einer umfassenden, erklärenden Rekonstruktion der antiken Kultur und Gesellschaft zugrunde liegen. Die Geschichte der Kunst des Alterthums hat ein einflussreiches Modell dafür geliefert, was eine solche Rekonstruktion in einer Zeit leisten konnte, in der die klassische Philologie einer erheblichen Umstrukturierung als „Alterthums-Wissenschaft“ durch Gelehrte wie Christian Gottlob Heyne und Friedrich August Wolf unterzogen wurde. Die vorliegende Untersuchung ihrer kritischen Reaktionen auf Winckelmanns Schriften soll dazu beitragen, sowohl die frühe Rezeption seines Werkes als auch Fragestellungen, die heute noch aktuell sind, besser zu verstehen.

Although social networking sites (SNSs) present a great deal of opportunities to support learning, the privacy risk is perceived by learners as a friction point that affects their full use for learning. Privacy risks in SNSs can be divided into risks that are posed by the SNS provider itself and risks that result from user’s social interactions. Using an online survey questionnaire, this study explored the students’ perception of the benefits in using social networking sites for learning purposes and their perceived privacy risks. A sample of 214 students from Uganda Christian University in Africa was studied. The results show that although 88 % of participants indicated the usefulness of SNSs for learning, they are also aware of the risks associated with these sites. Most of the participants are concerned with privacy risks such as identity theft, cyber bullying, and impersonation that might influence their online learning participation in SNSs.
