A later Hellenistic debate about the value of Classical Athenian civic ideals? The evidence of epigraphy, historiography and philosophy
Full text linkBook synopsis: In the Hellenistic period (c.323-31 BCE), Greek teachers, philosophers, historians, orators, and politicians found an essential point of reference in the democracy of Classical Athens and the political thought which it produced. However, while Athenian civic life and thought in the Classical period have been intensively studied, these aspects of the Hellenistic period have so far received much less attention. This volume seeks to bring together the two areas of research, shedding new light on these complementary parts of the history of the ancient Greek polis.
The essays collected here encompass historical, philosophical, and literary approaches to the various Hellenistic responses to and adaptations of Classical Athenian politics. They survey the complex processes through which Athenian democratic ideals of equality, freedom, and civic virtue were emphasized, challenged, blunted, or reshaped in different Hellenistic contexts and genres. They also consider the reception, in the changed political circumstances, of Classical Athenian non- and anti-democratic political thought. This makes it possible to investigate how competing Classical Athenian ideas about the value or shortcomings of democracy and civic community continued to echo through new political debates in Hellenistic cities and schools. Looking ahead to the Roman Imperial period, the volume also explores to what extent those who idealized Classical Athens as a symbol of cultural and intellectual excellence drew on, or forgot, its legacy of democracy and vigorous political debate. By addressing these different questions it not only tracks changes in practices and conceptions of politics and the city in the Hellenistic world, but also examines developing approaches to culture, rhetoric, history, ethics, and philosophy, and especially their relationships with politics
Transition metal nitride materials For supercapacitor applications
No full textThere is a pressing need to develop more environmentally friendly ways to generate and store electrical energy. Current technology for this is limited by the speed at which power storage can absorb and store the energy generated. To this end, transition metal nitride materials have been investigated with the aim of creating a nitride based supercapacitor.Ti(NEt2)4 and V(NEt2)4 were prepared and there, and Ta(NMe2)5’s, sol-gel chemistry was explored. These sols were infiltrated into multilayer templates, composed of hexagonally close packed opalescent crystals of DVB crosslinked amidine capped polystyrene spheres and heated under flowing ammonia to give metal nitride inverse opals exhibiting long range order and specific capacitances of upto 2 F g-1. Solid (Ti,V)N solutions were also synthesised and tested electrochemically as supercapacitor electrode materials.TiN and VN foils were prepared and subjected to a range of surface treatments. Their specific capacitances at a range of scan rates were measured to ascertain which surface treatment gave the highest capacitive performance
Approaching the Hellenistic polis through modern political theory: the public sphere, pluralism and prosperity
No full textBook snopsis: There is a long history of successful engagement between social science and classical studies. Social science has been a source of new and productive approaches to understanding ancient Greece, while classical Greek history and culture has been a touchstone for social theorists since the 19th century. This new collection of essays surveys the current state of the new field of ‘social science Greek history’ and demonstrates the potential of this interdisciplinary field.
Substantial bodies of work that have contributed in fundamental ways to our understanding of classical Greece and its cultural legacy were produced in 20th century, by employing methods from anthropology, sociology, and psychology. More recently, the use of quantitative methods and formal theory, drawn from contemporary political science, economics, and sociology, has led to a new understanding of ancient Greek economic and political development. Meanwhile, normative considerations, drawn from contemporary political philosophy, have led to a richer understanding of Greek political thought and Greek institutional innovations – notably including democracy and the rule of law

Effect of oxidative surface treatments on charge storage at titanium nitride surfaces for supercapacitor applications
No full textThe effects of surface oxidation on the capacitance of titanium nitride electrode surfaces, produced by reaction of titanium foils with ammonia, are examined. Thermal oxidation and electrochemical oxidation both increase the amount of redox active oxide at the surface, but electrochemical oxidation is found to be more successful in increasing the capacitance
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
