Measurement of 5-eV atomic oxygen using carbon-based films: preliminary results
No full textCarbon-based sensors have been developed to measure the atmospheric neutral atomic oxygen (AO) flux experienced by spacecraft in low Earth orbit. Thin- and thick-film carbon sensor elements were deposited onto an alumina substrate between thick-film gold tracks and silver palladium solder pads. AO flux is deduced by measuring resistance changes as the carbon film erodes and applying a simple theory. A wide range of responses were observed that are dependent on the deposition process and post deposition annealing. The deposition methods used were dc magnetron sputtering, e-beam evaporation, and screen-printing. The sensors tested compare favorably with similar silver-based sensors that have been flown previously on small satellite missions with significant mass/power constraints
A theory of alternative methods for measurements of absorption cross section and antenna radiation efficiency using nested and contiguous reverberation chambers
No full textAverage ACS can be measured in a reverberation chamber; however, the existing technique determines a value that includes the effects of the radiation efficiencies of the antennas used in the measurement. Correcting for these necessitates further complex measurements. Here we present the theory of an alternative measurement methodology using two nested or contiguous reverberation chambers which is free from errors caused by the radiation efficiencies of the antennas. The new method is based on the theoretical average transmission cross sections (TCSs) of circular holes in a metal plate between the two chambers. In fact the method can be viewed as an accurate transfer calibration measurement between TCS and ACS that is independent of both the chamber and antenna characteristics. Further, since the existing method of measuring ACS includes the effects of the radiation efficiencies of the antennas, a comparison of the ACS of a reference object, measured using both the existing and new methods, also provides an alternative method of determining radiation antenna efficiency. Measurement uncertainties for both alternative measurement methods – ACS and antenna radiation efficiency – are also derived
W R B executive summary
No full text"Alternative futures analysis is an environmental assessment approach for helping communities make decisions about land and water use. Its role is to provide a long-term, large-area perspective on the combined effects of the multiple policies and regulations affecting the quality of the environment and natural resources within a geographic area. The alternative futures process helps community members articulate and understand their different viewpoints, priorities, and goals. The product of the process is a suite of alternative 'visions' for the future expressed as maps of land use and land cover that reflect the likely outcomes of the options being advocated. Potential effects of these alternative futures are then evaluated for a wide array of ecological and socio-economic endpoints (i.e., things people care about). By capturing the essential elements of a complex debate in a fairly small number of alternative futures, and combining them with an objective evaluation of the consequences of each choice, this process can help groups move toward common understanding, and possible resolution and collective action. Here we summarize results from an alternative futures analysis conducted in the Willamette River Basin in western Oregon"--Page 1.conducted by the Pacific Northwest Ecosystem Research Consortium, consisting of scientists from EPA, Oregon State University, and the University of Oregon; Joan P.

Gregory of Nyssa\u27s Contra eunomium : Context, method, and theology
No full textThis dissertation examines Gregory of Nyssa\u27s Contra Eunomium, a fourth-century Christian theological and polemical text. This is one of the longest and most densely argued texts of the Greek patristic tradition. Gregory engages the second defense of Eunomius of Cyzicus by adopting a commentary-like format in which he first quotes a section of Eunomius\u27s text and then refutes it. The first half of the dissertation places the Contra Eunomium within the context of its author\u27s life, the fourth-century theological debates, its genre, and late-ancient textual practices. The second half of the dissertation examines the major theological topics of the three books of the Contra Eunomium and how these theological ideas intersect with the form of the refutation. In sum, Gregory attempts to cast his opponent outside of proper Christian intellectual practices all the while drawing on his own theological positions to support his view of the Christian intellectual life and its emphasis on texts and writing. Moreover, the dissertation shows that the Contra Eunomium drew on classical rhetoric, earlier Christian heresiological traditions, and ancient methods of engaging and interpreting authoritative texts. In this way, it claims that the Contra Eunomium reveals the growing importance of textual communities and of Christian reflection on written texts in the fourth century

Religion and the New Atheism: A Critical Appraisal
No full textGregory R. Peterson is a contributing author, Ethics, Out-Group Altruism, and the New Atheism.”
Book description: The term new atheism has been given to the recent barrage of bestselling books written by Richard Dawkins, Sam Harris, Daniel Dennett, Christopher Hitchens, and others. These books and their authors have had a significant media presence and have only grown in popularity over the years. This book brings together scholars from religious studies, science, sociology of religion, sociology of science, philosophy, and theology to engage the new atheism and place it in the context of broader scholarly discourses. This volume will serve to contextualize and critically examine the claims, arguments and goals of the new atheism so that readers can become more informed of some of the debates with which the new atheists inevitably and, at times unknowingly, engage.https://openprairie.sdstate.edu/hppr_book/1011/thumbnail.jp
Author Co-Citation Analysis (ACA): a powerful tool for representing implicit knowledge of scholar knowledge workers
No full textIn the last decade, knowledge has emerged as one of the most important and valuable organizational assets. Gradually this importance caused to emergence of new discipline entitled ―knowledge management‖. However one of the major challenges of knowledge management is conversion implicit or tacit knowledge to explicit knowledge. Thus Making knowledge visible so that it can be better accessed, discussed, valued or generally managed is a long-standing objective in knowledge management. Accordingly in this paper author co- citation analysis (ACA) will be proposed as an efficient technique of knowledge visualization in academia (Scholar knowledge workers)
The reception of Qoheleth in a selection of rabbinic, patristic and nonconformist texts
No full textThe purpose of this thesis is to examine the reception of the text of Qoheleth in a selection of rabbinic, patristic and nonconformist literature. The differences in the act of reading, reception and response to this text in discrete
Judaic and Christian locations is examined. The source texts that are considered are Qoheleth Rabbah, Targum Qoheleth, Gregory of Nyssa's homilies and Matthew Henry's exposition on Ecclesiastes. The thesis further investigates historical and theological experiential influences on the reception of Qoheleth as portrayed by the source texts. The text of Qoheleth and its history of interpretation, and the value of
examining the reception of the text by specific readers from a variety of contexts are discussed in the first chapter. In the consecutive chapters the reception of Qoheleth by each source text is examined individually. The historical and
theological contexts of each source text are described, including literary traditions and exegetical principles.
In the detailed examination of the source texts, the textual structural challenges that Qoheleth poses and how and why
they are responded to by the author(s) of the source texts are analysed. The final chapter compares and contrasts the main issues raised by the differing readings of Qoheleth, including the identity of Solomon and the view of God, and also, the differing contextual perspectives in which the reception process took place. Finally, a brief examination of a modem reader's (Michael V Fox') reception of Qoheleth is contrasted with that of earlier readers of the text. The manner in which the potential effects of Qoheleth are actualised and the process of meaning production varies between readers, being conditioned by their historical horizon
Hilary Putnam\u27s Semantic Scientism: A Critique
No full textThis author is puzzled by and disagrees with Putnam’s theory of meaning. In particular, the author argues that there can be a gap between scientific meaning and acceptable normal use, thereby showing the tension between Putnam’s scientism and his attention to linguistic communities. Part of the problem is Putnam’s imprecision, given that he neither argues for why we should privilege scientific classification, nor helps us draw the boundary surrounding our linguistic community. The author cites commentator Gregory McCulloch a great deal to help summarize and grasp Putnam’s project, thereby necessitating a discussion of McCulloch’s own “the understanding tracks real essence” doctrine as well as analyses of Putnam’s Twin Earth, beech/elm, “bonnet” and “robin” scenarios. Even if we are attracted to Putnam’s theses that 1) resemblance to a representation is not sufficient for representation, and 2) syntactic and phonetic similarity is not sufficient for co-extension, Putnam’s theory does not add up
Representing Different Constituencies: Electoral Rules in Bicameral Systems in Latin America and Their Impact on Political Representation
No full textThis article analyzes the quantitative (mechanical) effects and qualitative (perceptions) effects on political representation of the election of two separate chambers in Latin America’s bicameral systems. After discussing the spread and strength of bicameralism in Latin America, we compare the different electoral systems for lower chambers and Senates. Our study shows that in a region characterized by relatively high levels of malapportionment in the first chamber, the second chamber reinforces the malapportionment in parliament. Representation tends to be much more disproportional in the upper chamber than in the lower house. Moreover, the differences in the electoral systems and district magnitudes for both chambers make it more difficult for women to win a seat in the Senate.Latin America, Senates, bicameralism, electoral systems, malapportionment, gender quota
