    The Virtue of Civility in the Practice of Politics (Chapter Three of The Virtue of Civility in the Practice of Politics)

    Excerpt: This chapter has more than one goal. First, I want to introduce readers to the apparatus of practices, institutions and virtues (PIV) that helps us understand what virtues are. Second, I want to explore the notion of politics a little, to see what its main problem is. (I will claim, perhaps surprisingly, that business management is largely a variation of politics.) Third, I want to reintroduce civility and suggest that it is an important contributor to solving the political problem (and problems of management). Throughout this chapter, I will emphasize process. As we shall see, process is integrated in more than one way into the whole structure of virtues, as we learn what virtues are and as we train ourselves in them. Already, in chapter one, I suggested that controversies are processes in which we can seek truth. The writing and reading of books constitute another process in which we can seek truth. I hope that the things I write here will contribute to a wider discussion of the virtue of civility, a discussion which may promote truth, even if the particular ideas I espouse here turn out to be wrong

    From Praha to Prague: Assimilation and ethnic identity in an American farm town, Prague, Oklahoma, 1891-1930

    Scope and Method of Study: The purpose of this study was to examine the experiences of an immigrant group living in a rural environment in the midst of a larger native-born population. The group chosen were Czechs, who settled in the southeastern corner of Lincoln County, Oklahoma after participating in the 1891 Sac and Fox Land Run. The principal sources were manuscript census records, local newspapers, and various town records such as church membership rolls and baptismal records, cemetery, and the minutes and account books of the Bohemian Hall. In addition to primary sources, extensive secondary research is included in the study.Findings and Conclusions: This work elucidated a little-researched phenomenon: the dilemmas of an immigrant group living amongst a larger primarily native-born white population in a small, somewhat isolated farm town. A primary assertion of the work is that the Czechs of Prague, Oklahoma underwent cultural and structural assimilation more rapidly than Czechs in urban environments or Czechs living in homogeneous rural areas. The reasons for this were many, including the frontier environment of the community which forced the residents to cooperate in order for the town to succeed. Other rationales for the rapid acculturation included the size and rural location of Prague and the fact that the town also included an African American community, which absorbed the brunt of discrimination. A sub-thesis of the dissertation is that despite the quick acculturation, the Czech newcomers established a permanent presence in the small farming town on the edge of the Great Plains. The ethnic group maintained their identity as Bohemians, not in the multicultural sense whereby they steadfastly held to their native tongue and native ways, nor in a symbolic sense in which the only remaining vestiges are public festivals and kolache cafes, but in a much deeper, existential sense they remained Czech; they preserved and passed on an internal sense of distinctiveness

    Helicopter far-field acoustic levels as a function of reduced main-rotor advancing blade-tip Mach number

    Get PDF
    During the design of a helicopter, the weight, engine, rotor speed, and rotor geometry are given significant attention when considering the specific operations for which the helicopter will be used. However, the noise radiated from the helicopter and its relationship to the design variables is currently not well modeled with only a limited set of full-scale field test data to study. In general, limited field data have shown that reduced main-rotor advancing blade-tip Mach numbers result in reduced far-field noise levels. The status of a recent helicopter noise research project is reviewed. It is designed to provide flight experimental data which may be used to further understand helicopter main-rotor advancing blade-tip Mach number effects on far-field acoustic levels. Preliminary results are presented relative to tests conducted with a Sikorsky S-76A helicopter operating with both the rotor speed and the flight speed as the control variable. The rotor speed was operated within the range of 107 to 90 percent NR at nominal forward speeds of 35, 100, and 155 knots

    Asymmetric synthesis of tri- and tetrasubstituted trifluoromethyl dihydropyranones from alpha-aroyloxyaldehydes via NHC redox catalysis

    We thank the Royal Society for a University Research Fellowship (A.D.S.), and the European Research Council under the European Union’s Seventh Framework Programme (FP7/2007-2013) ERC Grant Agreement No. 279850 (A.T.D.).The asymmetric synthesis of tri- and tetrasubstituted trifluoromethyl dihydropyranones via an NHC-catalyzed redox process, introducing methyl, benzyl, and aryl substituents to the C(5) position, is presented. Their substrate-controlled derivatization into δ-lactones and cyclic hemiacetals containing stereogenic trifluoromethyl groups is also described.PostprintPeer reviewe

    Wolf-Rayets in IC10: Probing the Nearest Starburst

    Get PDF
    IC10 is the nearest starburst galaxy, as revealed both by its Halpha surface brightness and the large number of Wolf-Rayet stars (WRs) per unit area. The relative number of known WC- to WN-type WRs has been thought to be unusually high (~2), unexpected for IC10's metallicity. In this Letter we report the first results of a new and deeper survey for WRs in IC10. We sucessfully detected all of the spectroscopically known WRs, and based upon comparisons with a neighboring control field, estimate that the total number of WRs in IC10 is about 100. We present spectroscopic confirmation of two of our WR candidates, both of which are of WN type. Our photometric survey predicts that the actual WC/WN ratio is ~0.3. This makes the WC/WN ratio of IC 10 consistent with that expected for its metallicity, but greatly increases the already unusually high number of WRs, resulting in a surface density that is about 20 times higher than in the LMC. If the majority of these candidates are spectroscopically confirmed, IC10 must have an exceptional population of high mass stars.Comment: Accepted by ApJL; only minor correction in this versio
