Schaeffer est mort! Long live Schaeffer!
No full textThis paper examines two groups of composers and discusses the commonality in their approach to using concrete sound materials and rhythm in their works. As a result of this commonality an examination of the ways in which these composers have expanded the electroacoustic language through the hybridisation of electronica and musique concrete techniques is undertaken. It will then be demonstrated how these works, whilst pushing at the boundaries of electroacoustic music can nevertheless be discussed and analysed with reference to Emmerson’s language grid as originally proposed in The Relation of Language to Materials (1986: 17-39). It will be demonstrated how, with the advent of the sampler and proliferation of works utilizing concrete materials, Emmerson’s language grid can be used as the basis for a wider discussion of electronic works
Acute Ethanol Administration Rapidly Increases Phosphorylation of Conventional Protein Kinase C in Specific Mammalian Brain Regions in Vivo
No full textBackground
Protein kinase C (PKC) is a family of isoenzymes that regulate a variety of functions in the central nervous system including neurotransmitter release, ion channel activity, and cell differentiation. Growing evidence suggests that specific isoforms of PKC influence a variety of behavioral, biochemical, and physiological effects of ethanol in mammals. The purpose of this study was to determine whether acute ethanol exposure alters phosphorylation of conventional PKC isoforms at a threonine 674 (p-cPKC) site in the hydrophobic domain of the kinase, which is required for its catalytic activity.
Methods
Male rats were administered a dose range of ethanol (0, 0.5, 1, or 2 g/kg, intragastric) and brain tissue was removed 10 minutes later for evaluation of changes in p-cPKC expression using immunohistochemistry and Western blot methods.
Results
Immunohistochemical data show that the highest dose of ethanol (2 g/kg) rapidly increases p-cPKC immunoreactivity specifically in the nucleus accumbens (core and shell), lateral septum, and hippocampus (CA3 and dentate gyrus). Western blot analysis further showed that ethanol (2 g/kg) increased p-cPKC expression in the P2 membrane fraction of tissue from the nucleus accumbens and hippocampus. Although p-cPKC was expressed in numerous other brain regions, including the caudate nucleus, amygdala, and cortex, no changes were observed in response to acute ethanol. Total PKC? immunoreactivity was surveyed throughout the brain and showed no change following acute ethanol injection
Sports Fans' Evaluations of Sporting Code Innovations
No full textToday's professional sports are frequently evolving and changing their design, structure and format. Many such innovations have been spurred on by the opportunity to capitalise financially on new markets and increase profit. This study used both quantitative (survey) and qualitative (depth interviews) methods in order to examine fans' attitudes towards the current state of Rugby Union, Rugby League, Netball, Soccer and Cricket. The findings for Rugby Union concluded that the recent experimental law variations have succeeded in what they were introduced to do. Fans believe that Rugby is more exciting to watch than ever before and that it is now a faster and more attack-focused contest. Fans believe that Rugby League has improved following the introduction of the video referee and in particular by the use of two on-field referees. They believe that it is now a more exciting and faster game. Fans also believe that salary caps are good for Rugby League and help to increase competition and spread the wealth of talent among the teams. Netball fans are excited by possible new innovations and show support for the inclusion of power plays, two point goals, rolling substitutions and increased physical contact. Fans believe that Soccer needs to adopt technology in order to help its officials but they also admire the traditionalism of the code. Surprisingly, fans show support for increasing the sizes of Soccer‟s goals in order to make it easier for teams to score. Fans show support for Twenty20 cricket and seem undeterred by recent match fixing scandals. There is also evident support for the introduction of Beach Cricket to New Zealand. Analysing fans' attitudes towards professional sport's product innovations has led to a final implication and conclusion for the administrators and governing bodies of professional sport. That is, it would be wise to keep the traditional codes and their formats as traditional as possible. However, evolve the same sport in to a completely separate format in order to financially capitalise on different markets. Twenty20 cricket is a perfect example of this
Design of microcavity resonators for single-atom detection
No full textWhispering gallery modes of a microdisk resonator are useful for the optical detection of single rubidium and cesium atoms near the surface of a substrate. Light is coupled into two high-Q whispering-gallery modes of the disk which can provide attractive and/or repulsive potentials, respectively, via their evanescent fields. The sum potential, including van der Waals/Casimir-Polder surface forces, may be tuned to exhibit a minimum at distances on the order of 100nm from the disk surface. Simultaneously optically trapping and detecting is possible, with the back-action of an atom held in this trap on the light fields being sufficiently strong to provide a measurable effect. Atom trapping and detection depend on a variety of system parameters and experimental realizations differ for different atoms

These last species in turn present higher snout to dorsal-fin origin distance than <i>C. oliverai</i> and <i>C. aleni</i> (higher negative value of CV1, p<0.05). In addition, <i>C. oliverai</i> could be discriminated from the other three species on the second canonical axis, based on higher body depth (higher positive values of CV2, p<0.05) whereas, <i>C. spilurus-hauxwellianus</i>, <i>C. alleni</i> and <i>P. kennedyi</i> presented greater head depth and head length than <i>C. oliverai</i> (higher negative value of CV2, p<0.05).</p> <p> <b>Discussion.</b> Eigenmann (1927:330–336), in the first revisionary study after the original description of the genus, recognized <i>Ctenobrycon hauxwellianus</i> (Cope), from Amazon basin; <i>C. spilurus</i> (Valenciennes), from Venezuela and Suriname; and <i>C. multiradiatus</i> (Steindachner), from Amazon basin and possibly Paraguay basin. This author diagnosed <i>C. hauxwellianus</i> from <i>C. spilurus</i> uniquely by the average of the body depth (2.0 times in SL versus 2.5 times in SL, respectively). Eigenmann, however, was not sure about the validity of <i>C. multiradiatus</i>, since he considered that the diagnostic characters used by Steindachner could be purely individual variations and also pointed out that the forms from Paraguay were most likely <i>Astyanax alleni</i> Eigenmann & MacAtee, or <i>A. pelegrini</i> Eigenmann or even <i>Psellogrammus kennedyi</i> Eigenmann. Géry (1977), reallocated <i>Astyanax alleni</i> in <i>Ctenobrycon</i> but, due to the great overlap in the characters, named the subspecies <i>C. spilurus spilurus</i>, <i>C. spilurus hauxwellianus</i>, and <i>C. spilurus alleni</i>. Besides, this author also cited <i>C. multiradiatus</i> and <i>C. correntinus</i> as valid, but argued that these were probably synonyms of <i>C. hauxwellianus</i> and <i>Astyanax pelegrini</i>, respectively. Notwithstanding the syntypes of <i>C. spilurus</i> and <i>C. hauxwellianus</i> are inadequately preserved, which further hinders the process of delineating these species, we herein recognized <i>C. hauxwellianus</i> (Cope, 1870) as a junior synonym of <i>C. spilurus</i> (Vallenciennes), based on the examination of the comparative lots of <i>Ctenobrycon</i>, which did reveal a substantial overlap for all morphometric and meristic characters, not supporting the diagnostic characters presented by Eigenmann (1927) for <i>C. spilurus</i> and <i>C. hauxwellianus</i>. <i>Ctenobrycon alleni</i>, however, could be easily distinguished from congeners by presenting two humeral blotches versus a single one, a condition already described by Britski, 2007.</p> <p> Taking into account this great overlap in characters, a given count that falls totally out of the known range of <i>Ctenobrycon</i> is strong evidence that it is related to a different species. From the 235 examined comparative specimens, all of them presented up to 13 scale rows above the lateral line (<i>vs.</i> 14 –15 in <i>C. oliverai</i>). Moreover, no comparative material from río Orinoco drainage has more than 12 scale rows above lateral line, which enhance our decision of considering this species as new rather than a population which would only widen the variation range observed for <i>Ctenobrycon spilurus</i>. The results of the multivariate analysis corroborate our hypothesis showing statistically significant evidences which discriminate <i>Ctenobrycon oliverai</i> from <i>C. spilurus</i> and <i>Psellogrammus kennedyi</i>.</p> <p> Lima <i>et al.</i> (2003) listed <i>Tetragonopterus correntinus</i> Holmberg, <i>T. gibbicervix</i>, Pelegrin, <i>T. multiradiatus</i> Steindachner and <i>Astyanax pelegrini</i> Eigenmann as <i>species inquirendae</i> in <i>Ctenobrycon</i>. Nonetheless, Mirande <i>et al.</i> (2006) considered both <i>Tetragonopterus correntinus</i> and <i>Astyanax pellegrini</i>, species of <i>Astyanax</i> rather than <i>Ctenobrycon</i>, since these do not display the spinoid scales, which promptly separate these taxa from our new species (that presents spinoid scales). According to Mirande’s (2010) examinations, the scales of the belly of <i>Psellogrammus kennedyi</i> have simple flattened serrations restricted to the margin of the scales similar to that of crenate scales in the classification of Roberts (1993). However, our examinations indicated that the form of the scales of the belly in both <i>Ctenobrycon</i> and <i>Psellogrammus</i> species are, in fact, spinoid, with acute projections not restricted to the margin of the scales (Fig. 5).</p> <p> Examination of images of three syntypes of <i>Tetragonopterus gibbicervix</i>, made it clear that this species presents 12 scale rows above lateral line, which distinguishes it from our new species (that presents 14–15 scale rows above lateral line).</p> <p> Géry (2006) affirmed that <i>Tetragonopterus multiradiatus</i> Steindachner is a junior synonym of <i>C. hauxwellianus</i>, but did not expose the reasons for considering so, nor de he mention the paper where this new combination was proposed, if it exists at all. Considering that the syntypes of <i>Tetragonopterus multiradiatus</i> are possibly lost (see Lima <i>et al.</i>, 2003), not much information can be retrieved but from Steindachner’s original description and putative topotypes. The eight examined specimens from the type locality (MZUSP 27765, município de Tefé, AM, Brazil) presented one tooth in the maxillary bone, 45 to 49 scales in the lateral line, and 11 to 12 scale rows above lateral line and 9 to 10 scale rows below lateral line, perfectly fitting with <i>C. hauxwellianus</i> (= <i>C. spilurus</i>), according to the key presented by Eigenmann. In fact, none of the herein examined morphotypes of <i>Ctenobrycon</i> presented toothless maxillaries and 41–42 lateral line scales as described for <i>T. multiradiatus</i> by Steindachner (1876) and, thus, there are not enough elements to assure that <i>C. multiradiatus</i> is a junior synonym of <i>C. spilurus</i> or even if it is a species of <i>Ctenobrycon</i>, if we consider that no mention was made on the presence of spinoid scales in <i>C. multiradiatus</i>, be it in its original description or elsewhere.</p> <p> <b>Comparative material.</b> <i>Ctenobrycon alleni</i>: LIRP 3786 (n=1), Brasil, Mato Grosso do Sul, Porto Manga, rio Paraguai; MZUSP 54023 (34) (1 C&S), Paraguai, Concepcion, Puerto Itacua, rio Paraguai; <i>Ctenobrycon spilurus</i>: Brazil: MZUSP 5156 (28), Roraima, Surumu, rio Surumu; MZUSP 5601 (22), Pará, Oriximiná, rio Trombetas, Lago Parú; Amazonas: LIRP 4999 (21) (3 C&S), Janauari, Lago Terra Preta; LIRP 4965 (10), Janauaca, Lago Castanho; LIRP 4985 (2), Camaleão, Ilha de Marchantaria, rio Amazonas; MZUSP 27765 (8), Tefé, baixo rio Japurá; MZUSP 54495 (8), Equador, Napo, rio Yasuní; Brazil, Acre, Cruzeiro do Sul, rio Moa: LBP 4047 (4), (1 C&S) LBP 4151 (2), rio Japiim: LBP 4095 (20); Peru, Ucayali, Província de Coronel Portilho, rio Ucayali: MZUSP 25996 (1); MZUSP 26242 (8); Suriname, Paramaribo: ANSP 137053 (3); Venezuela, Guárico: MCP 15138 (5), Camaguán, río Portuguesa; MZUSP 74698 (3), San Fernando, río Guárico; Bolívar, Caicara Del Orinoco: LBP 2232 (11), (2 C&S), río Orinoco; LBP 2222 (2), Laguna de Castilleros; <i>Psellogrammus kennedyi</i>: LBP 3220 (24) (3 C&S), Brasil, Mato Grosso, Nobres, rio Cuiabazinho, Lagoa Marginal; <i>Tetragonopterus alleni</i>: FMNH 52634, paratype, Brasil, Mato Grosso, Corumbá. <i>Tetragonopterus gibbicervix</i>: NMW 57516, syntype, Brazil, Amazonas, Teffé (photo), MNHN 1909-182, paratype (photo); MNHN 1909-320/321, 2 paratypes (photos); <i>Tetragonopterus hauxwellianus</i>: ANSP 8138-8142, 5 paratypes, Pebas, Peru. <i>Tetragonopterus spilurus</i>: MNHN 5341, syntype (photo).</p>Published as part of <i>Benine, Ricardo C., Lopes, Guilherme A.

The Liberal Arts on Trial: the Inside Story and Legacy of the 1939 \u27Red Scare\u27 Firing of College President Charles H. Fisher
No full textExpanding on his recent History Master\u27s thesis, veteran Seattle Times reporter and adjunct Western Washington University Journalism instructor Ron Judd examines the successful 1930s ‘Red Scare’ political campaign to remove Western Washington College of Education President Charles H. Fisher from office. Judd\u27s presentation places Fisher\u27s firing for the first time in the context of local and national anti-communist, super-patriot political trends. His study, based on archival research conducted in the collections of Heritage Resources, places Fisher squarely in the crossfire of a prolonged, bitter political war between New Deal liberals and old-guard conservatives in Bellingham, and examines whether the forced removal of Fisher by radical political operatives could happen in Washington state today.
Ron C. Judd is a journalism instructor and Freshman Interest Group seminar leader at Western Washington University, and a 2015 James W. Scott Research Fellow at the Center for Pacific Northwest Studies (a program of Western Libraries Heritage Resources). A 1985 graduate of Western with a Bachelor of Arts in History and Journalism, his 30-year career in journalism has included stints covering general news, higher education, the outdoors and the environment, professional sports, and seven Summer and Winter Olympic Games for The Seattle Times and other publications. He currently writes a Sunday news column, The Wrap, as well as in-depth profiles and essays on environmental, historical, and Northwest-lifestyle topics forPacific NW, the Seattle Times\u27 Sunday magazine. One of his recent provocative magazine pieces, defining the traits of a true Northwest native, was selected by a historical committee to be sealed in a Washington State Archives time capsule that will be opened in 375 years, to celebrate the state\u27s 500th anniversary. A three-time nominee for the Pulitzer Prize in feature writing and investigative reporting, he also is the author of numerous works of humor and nonfiction, including a spectator\u27s guide/history of the Winter Olympics. His presentation today, based largely on research of primary documents from the archives of Western\u27s Heritage Resources, is drawn from his thesis for a Master of Arts in History program at the University of Nebraska, where he has concentrated on the political, religious and cultural history of the Pacific Northwest from 1900 to 1950. As part of his change in emphasis, he continues to strive to modify his writing style from plain old English to full-on academic jargon -- with what he calls decidedly mixed results
