Gunfighter gaps : Discourses of the frontier in Hollywood movies of the 1930s and 1970s.

In 1990 and 1992, the Academy Award for the Best Motion Picture of the year was won by movies belonging to the Western genre: Dances With Wolves, and Unforgiven. Recent work on the Western claims that these achievements and the flood of new Westerns dating from the late 1980s up to the present signal a renaissance of the genre within the film industry, and among critics and the public. The notion of a revival has attached to it the idea of a preceding lapse, when a movie genre is "out of fashion". The lapse experienced by the Western beginning in the mid-1970s has a clear parallel in the late 1920s, when the trade press announced the demise of the genre. The aim of this thesis is to argue that these periods of lull in the popularity of the Western are tied to historical events that directly undermined the ideological base of American thought and culture. A principal aspect of that ideological base is the American Myth of the Frontier. In the 1930s the myth was challenged by the Great Depression, and in the 1960s and 1970s, the Civil Rights Movement, Women's Liberation and Vietnam. In the latter era, an entire generation of young men, raised in the 'Golden era' of the Western when the frontier myth gained its widest currency, were inspired to charge into battle 9,000 miles from America's shores for a victory that was sanctioned by the past. The tragic consequences of that war exacerbated the failure of that national narrative of triumph, and as the most dominant vehicle of frontier mythology, the Western correspondingly encountered an obstacle to its popular reception. This present volume locates expressions of popular culture as barometers of the performance of myth. It has, as its subject, an account of the route via which the Myth of the Frontier was repaired, by focusing primarily on the gaps prior to the myth's re-emergence. The gaps identified are episodes when myth loses its dehistoricizing function, when the frontier becomes a moment in the past that has no relevance for the present. An examination of how historical memory is disabled through the movies reveals the pervasiveness and continued significance of the frontier myth to America's self-image.Prior histories of the Western observe moments of the genre's resurgence, but this thesis adds to the field of criticism in its exploration of the possible reasons underlying the restoration of its popularity. This is achieved through an analysis of the various genres to which the frontier myth migrates after the 'A' Western ceases to be an outlet for its discourse. The Gangster film, 'B' Western and Vietnam War movie are such surfaces of emergence. Part of the originality of this work, for example, is the research on the 'B' Westerns directed by Joseph Kane and starring Gene Autry. The gaps in the history of the Western are thus viewed positively as having the utility for comprehending the relationship between the Western genre and the frontier myth. After the introductory chapters which discuss the concepts of genre, myth and the Western, this thesis analyses the centrality of the historical events that challenged expressions of frontier mythology in the two periods identified and the process through which that history is mediated, reconstructed and finally replaced

The role of a labial salivary gland biopsy in the diagnostic procedure for Sjögren's syndrome: a study of 94 cases

Objectives: The purpose of the present study is to examine the role of the outcome of the labial salivary gland biopsy (LSGB) in the diagnostic procedure of patients suspected of suffering from Sjögren's syndrome (SS). Material and Methods: In a retrospective study the result of histopathological assessment of 94 consecutively taken labial salivary gland biopsies has been examined. For the diagnosis of SS the American-European Consensus Group classification (AECG, 2002) have been used. The outcome of the assessment has been discussed in relation to a recently reported classification provided by the American College of Rheumatology (ACR, 2012). Results: In the 94 LSGBs support for a diagnosis of SS has been encountered in 24 out of 26 patients with SS. In the 68 patients with a negative diagnosis of SS only six positive LSGBs were observed. The sensitivity of the labial biopsy amounted 0.92; the specificity was 0.91, while the positive predictive value and the negative predictive value amounted 0.80 and 0.97 respectively. LSGBs taken by or on the request of the departments of Rheumatology or Internal Medicine had a significant higher yield compared to LSGBs taken in other clinical departments. Conclusion s : The LSGB may play a role in the diagnostic procedure of Sjögren's syndrome when using either the AECG classification or the ACR classification. A LSGB should preferably taken after counseling for the possible presence of SS by a department of Rheumatology or Internal Medicine since the yield of such biopsies is much higher than in patients who have not been counseled by these departments prior to the taking of a LSGB. When using the ACR classification, a positive serologic result and a positive ocular test make the taking of a LSGB redundant. Only in case of a negative serologic outcome or a negative result of the ocular test a LSGB is indicated. Since both the serologic test and the ocular test carry hardly any morbidity, these tests should, indeed, be performed first before considering to take a LSGB

Epidemiology of invasive fungal diseases among patients with haematological disorders in the Asia-Pacific: a prospective observational study

AbstractWe conducted a 2-year multicentre prospective observational study to determine the epidemiology of and mortality associated with invasive fungal diseases (IFDs) among patients with haematological disorders in Asia. Eleven institutions from 8 countries/regions participated, with 412 subjects (28.2% possible, 38.3% probable and 33.5% proven IFDs) recruited. The epidemiology of IFDs in participating institutions was similar to Western centres, with Aspergillus spp. (65.9%) or Candida spp. (26.7%) causing the majority of probable and proven IFDs. The overall 30-day mortality was 22.1%. Progressive haematological disorder (odds ratio [OR] 5.192), invasive candidiasis (OR 3.679), and chronic renal disease (OR 6.677) were independently associated with mortality

Analysis of acoustic emission during the melting of embedded indium particles in an aluminum matrix: a study of plastic strain accommodation during phase transformation

Acoustic emission is used here to study melting and solidification of embedded indium particles in the size range of 0.2 to 3 um in diameter and to show that dislocation generation occurs in the aluminum matrix to accommodate a 2.5% volume change. The volume averaged acoustic energy produced by indium particle melting is similar to that reported for bainite formation upon continuous cooling. A mechanism of prismatic loop generation is proposed to accommodate the volume change and an upper limit to the geometrically necessary increase in dislocation density is calculated as 4.1 x 10^9 cm^-2 for the Al-17In alloy. Thermomechanical processing is also used to change the size and distribution of the indium particles within the aluminum matrix. Dislocation generation with accompanied acoustic emission occurs when the melting indium particles are associated with grain boundaries or upon solidification where the solid-liquid interfaces act as free surfaces to facilitate dislocation generation. Acoustic emission is not observed for indium particles that require super heating and exhibit elevated melting temperatures. The acoustic emission work corroborates previously proposed relaxation mechanisms from prior internal friction studies and that the superheat observed for melting of these micron-sized particles is a result of matrix constraint.Comment: Presented at "Atomistic Effects in Migrating Interphase Interfaces - Recent Progress and Future Study" TMS 201

Identification of Novel Craniofacial Regulatory Domains Located far Upstream of SOX9 and Disrupted in Pierre Robin Sequence.

Mutations in the coding sequence of SOX9 cause campomelic dysplasia (CD), a disorder of skeletal development associated with 46,XY disorders of sex development (DSDs). Translocations, deletions, and duplications within a ∼2 Mb region upstream of SOX9 can recapitulate the CD-DSD phenotype fully or partially, suggesting the existence of an unusually large cis-regulatory control region. Pierre Robin sequence (PRS) is a craniofacial disorder that is frequently an endophenotype of CD and a locus for isolated PRS at ∼1.2-1.5 Mb upstream of SOX9 has been previously reported. The craniofacial regulatory potential within this locus, and within the greater genomic domain surrounding SOX9, remains poorly defined. We report two novel deletions upstream of SOX9 in families with PRS, allowing refinement of the regions harboring candidate craniofacial regulatory elements. In parallel, ChIP-Seq for p300 binding sites in mouse craniofacial tissue led to the identification of several novel craniofacial enhancers at the SOX9 locus, which were validated in transgenic reporter mice and zebrafish. Notably, some of the functionally validated elements fall within the PRS deletions. These studies suggest that multiple noncoding elements contribute to the craniofacial regulation of SOX9 expression, and that their disruption results in PRS

Antimicrobial resistance profile of Salmonella present in organic farming in Selangor, Malaysia

Presence of Salmonella in organic farming may lead to contamination in fresh produce. This study was designed to detect Salmonella contamination in organic vegetable farm situated in Serdang and to evaluate the antibiotic susceptibility profiles of the isolates. A total of 460 samples of brinjal, cucumber, ladies’ fingers and soil were collected and examined for the presence of Salmonella. The obtained isolates were identified and confirmed by biochemical characterization and serotyping. Antibiotic sensitivity profiles of the isolates were determined by using agar disk diffusion method. Salmonella spp. was detected in brinjal (1.7%, n=2), cucumber (1.7%, n=2), ladies’ fingers (2.5%, n=3) and soil (5.0%, n=5) samples. The prevalent serovars were Salmonella enterica ser. Senftenberg, S. enterica ser. Weltevreden and S. enterica ser. Corvallis. All strains were resistance to penicillin and vancomycin, with multiple antibiotic resistance (MAR) index between 0.21 and 0.36, demonstrated here as multi-drug resistant (MDR) Salmonella. The result highlighted that organic vegetables constituted potential sources of Salmonella, informing continuous monitoring and tightened surveillance are necessary to ensure food safety

The energy spectrum of all-particle cosmic rays around the knee region observed with the Tibet-III air-shower array

We have already reported the first result on the all-particle spectrum around the knee region based on data from 2000 November to 2001 October observed by the Tibet-III air-shower array. In this paper, we present an updated result using data set collected in the period from 2000 November through 2004 October in a wide range over 3 decades between $10^{14}$ eV and $10^{17}$ eV, in which the position of the knee is clearly seen at around 4 PeV. The spectral index is -2.68 $\pm$ 0.02(stat.) below 1PeV, while it is -3.12 $\pm$ 0.01(stat.) above 4 PeV in the case of QGSJET+HD model, and various systematic errors are under study now.Comment: 12 pages, 7 figures, accepted by Advances in space researc

Moon Shadow by Cosmic Rays under the Influence of Geomagnetic Field and Search for Antiprotons at Multi-TeV Energies

We have observed the shadowing of galactic cosmic ray flux in the direction of the moon, the so-called moon shadow, using the Tibet-III air shower array operating at Yangbajing (4300 m a.s.l.) in Tibet since 1999. Almost all cosmic rays are positively charged; for that reason, they are bent by the geomagnetic field, thereby shifting the moon shadow westward. The cosmic rays will also produce an additional shadow in the eastward direction of the moon if cosmic rays contain negatively charged particles, such as antiprotons, with some fraction. We selected 1.5 x10^{10} air shower events with energy beyond about 3 TeV from the dataset observed by the Tibet-III air shower array and detected the moon shadow at $\sim 40 \sigma$ level. The center of the moon was detected in the direction away from the apparent center of the moon by 0.23$^\circ$ to the west. Based on these data and a full Monte Carlo simulation, we searched for the existence of the shadow produced by antiprotons at the multi-TeV energy region. No evidence of the existence of antiprotons was found in this energy region. We obtained the 90% confidence level upper limit of the flux ratio of antiprotons to protons as 7% at multi-TeV energies.Comment: 13pages,4figures; Accepted for publication in Astroparticle Physic
