The composition of nitrogen-doped hydrogenated amorphous carbon films grown in a magnetically confined rf plasma-enhanced chemical vapour deposition system has been determined by X-ray photoelectron spectroscopy and compared with that determined using a combination of elastic recoil detection analysis, Rutherford back-scattering and nuclear reaction analysis. The importance of nitrogen doping or 'incorporation' in hydrogenated amorphous carbon films is discussed in relation to the significant variation in the sp 2 -to-sp 3 ratio that takes place. At 7 at.% N in the (...) a-C : H matrix, a critical change in the microstructure is observed, which governs the resulting mechanical, optical and electronic properties. Finally, the correlation between the sp 2 and sp 3 fractions determined by a non-destructive method of obtaining the bond fractions and by electron-energy-loss spectroscopy is discussed, with a view to evaluating accurately the sp 2 fraction in a-C : H : N films.

Allthough small business accounts for over 90% of businesses in U.K. and indeed elsewhere, they remain the largely uncharted area of ethics. There has not been any research based on the perspective of small business owners, to define what echical delemmas they face and how, if at all, they resolve them. This paper explores ethics from the perspective of small business owner, using focus groups and reports on four clearly identifiable themes of ethical delemmas; entrepreneurial activity itself, conflicts of personal (...) values with business needs, social responsibility and the impact of owners' personality on business ethics. The mechanisms for resolving ethical dilemmas is not at all clear, as there appears to be a web of filters which are used in an inter-connected way. However a common starting point for resolving an ethical delemma which involves others is based on identifying who it is (e.g., a friend or institution) and the quality of the relationship with that person. The research yielded a rich source of material on business ethics and it is clear that future researchers must focus on this sector if business ethics is to make significant advances. (shrink)

Guidelines around the world require children to provide assent for their participation in most research studies. Yet, little further guidance is provided on how review committees should implement this requirement, including which children are capable of providing assent and when the requirement for assent may be waived on the grounds that the research offers participating children the potential for important clinical benefit. The present paper argues that the assent requirement is supported by the importance of allowing children who are capable (...) to make their own decisions. This suggests children are capable of assent when they become able to understand the research in question. While development varies across individual children, existing data suggest most children develop this ability by approximately age 14. Until instruments are developed to assess the assent capacity of individual children, this age should be used as the threshold for assent. In addition, the importance of protecting children from harm suggests that the sustained dissent of all children, including those who are unable to provide assent, should be respected. While the assent requirement may be waived when research participation offers the potential for important medical benefit that is unavailable outside the research context, analysis suggests that children’s sustained dissent should be respected in all cases.

This is an introduction to, and survey of, the constructive approaches to pure mathematics. The authors emphasise the viewpoint of Errett Bishop's school, but intuitionism. Russian constructivism and recursive analysis are also treated, with comparisons between the various approaches included where appropriate. Constructive mathematics is now enjoying a revival, with interest from not only logicans but also category theorists, recursive function theorists and theoretical computer scientists. This account for non-specialists in these and other disciplines.

The Intergovernmental Platform on Biodiversity and Ecosystem Services have recently launched themselves as the UN-sanctioned instrument for conserving nature. They seek to establish themselves as the authority in this field alongside the well-known Intergovernmental Panel on Climate Change in climate science. Quickly following or even before recent publication of their conceptual framework in two biology journals, they were already underway building upon it. This headlong push, we believe, is ill advised. We show how the framework is unsound as a foundation (...) for further work—in a number of ways and perhaps even by its authors’ own lights. It is therefore urgent that the IPBES thoroughly and thoughtfully reconsider their framework before too much effort is wasted. (shrink)

An investigation into some of the literary features of the book of Malachi reveals that each unit is structured in a twofold way. The macrostructure of the book also shows that the book can be divided into two parts. The results of this investigation strengthens the recent trend in the research of Malachi that it is unlikely that the book underwent an extensive redactional process over a period of time and that it is rather more likely that the book was (...) written in a relatively short period of time.

Marking the 50th anniversary of one among this philosopher's most distinguished pieces, Blumenberg's Rhetoric proffers a decidedly dialogic and diversified interaction with the essay polyvalently entitled 'Anthropological Approach to the Actuality and Topicality (or Currency, Relevance) of Rhetoric' (Anthropologische Annäherung an die Aktualität der Rhetorik), first published in 1971. Following Blumenberg's lead, the contributors consider and tackle their topics rhetorically, 'in utramque partem vel in plures'--treating (inter alia) the variegated discourses of Phenomenology, the History of Philosophy, Anthropology, and the téchne (...) itself from a plurality of viewpoints. Quasi in actu--as a mise en abyme of this rhetorical method par excellence--said accent on approaching any matter polyperspectivally is reflected in the proceedings of the live(ly) discussions having taken place in preparation for the present volume. Along with the diachronically extensive, disciplinarily diverse essays, this publication of the actual academic interplay--notably in the current lingua franca--will facilitate, and is to conduce to, further scholarship with respect to Blumenberg and the art of rhetoric.

Within the increasingly complex picture which has emerged in recent years of the manuscript tradition of Ovid's Amores the relationship of the two earliest MSS appears to remain firm: cod. P or Puteaneus of the 9th or early 10th century, which begins at Am. 1.2.51, was copied, probably directly, from the second half of the 9th-century cod. R or Regius , whose first half now ends at Am. 1.2.50. This view, which originates in S. Tafel's dissertation of 1910 and lies (...) behind the stemma constructed by E. J. Kenney for his OCT edition of 1961 , has come to be taken by Ovidian scholars to be the truth. My purpose in this first section is to show that this idea is unlikely to be the truth and, in the form in which it has most strongly been put forward, cannot be the truth. In the second section consequences for the manuscript tradition as a whole are explored. First we shall need some details. P, the slightly later manuscript, consists in all of 99 folia, of which 1–54 contain most, but not all, of the Heroides — not all, because they are in a lacunose state, a point to which we shall return in greater detail later. Foll. 55–6 are blank sheets of paper, not parchment, clearly inserted at a much later date during rebinding. (shrink)
