Comparing Wilson and Clover Quenched SU(3)SU(3) Spectroscopy with an Improved Gauge Action

We present results of quenched $SU(3)$ hadron spectroscopy comparing \order(a) improved Wilson (Clover) fermions with conventional Wilson fermions. The configurations were generated using an \order(a^2) improved 6-link $SU(3)$ pure gauge action at $\beta$'s corresponding to lattice spacings of $0.15$, $0.18$, $0.20$, $0.33$, and $0.43$ fm. We find evidence that fermionic scaling violations are consistent with \order(a^2) for Clover and \order(a) with a nonnegligible \order(a^2) term for standard Wilson fermions. This latter mixed ansatz makes a reliable continuum extrapolation problematic for Wilson fermions. We also find that the slope of the scaling violations is roughly $250 MeV$ for both Wilson and Clover fermions.Comment: 3 pages latex with 2 postscript figures. Talk presented at LATTICE96(spectrum

Quenched SU(3)SU(3) hadron spectroscopy using improved fermionic and gauge actions

We present results of quenched $SU(3)$ hadron spectroscopy using \order(a) improved Wilson fermions.

SCRI Results With the Tadpole-Improved Clover Action

We compare light hadron spectroscopy using the Wilson and Clover fermionic actions. We show that a Clover coefficient chosen using tadpole-improved tree-level perturbation theory effectively eliminates the O(a) discretization errors present in the Wilson action. We find that discretization errors in light spectroscopy for both the Wilson and Clover actions are characterized by an energy scale mu of about 200-300 MeV, indicating that these errors can be reduced to the 5% level by using the Clover action at an inverse lattice spacing of about 1.3 GeV.Comment: Talk presented at the International Workshop on Lattice QCD On Parallel Computers, University of Tsukuba, March 10-15 1997. 9 LaTex pages plus 6 postscript figures, uses espcrc2.st

One small step: Sound sources and events as the basis for auditory graphs.

Presented at the 11th International Conference on Auditory Display (ICAD2005)An overwhelming majority of auditory graphs employ a representational design that maps changes in a variable to changes in a ``low-level'' acoustic dimension such as frequency, intensity, or spectrum. However, there are several potential drawbacks to this type of auditory graph design. First, the perceptual correlates of these dimensions (pitch, loudness, and timbre) have been shown to interact perceptually such that changes in one dimension can influence judgments about changes in the others. Second, abstract changes in acoustic dimensions typically fail to invoke any kind of mental model that might help the listener represent cognitively the changes that occur in the data. Finally, listeners often are much better at attending to acoustic sources (the objects producing the sound) and acoustic events (the actions of these sounding objects) than to the low-level acoustic dimensions themselves. In this paper we endorse an approach to mapping data to sound that ties acoustic parameters unambiguously to changes in sound source or event characteristics. This type of design might be achieved by changing complex acoustic features along one axis in a manner that corresponds with a basic physical feature of a sound source or event

Влияние горнодобывающей промышленности на регионы России

В данной статье рассмотрено влияние горнодобывающей промышленности на экологическую ситуацию регионов России, к ним относится: Кузнецкий, Иркутский, КанскоАчинский, Южно-Якутский и Донецкий каменноугольные бассейны. Проанализированы последствия горной добычи. Выявлены методы борьбы с загрязнением окружающей среды. Установлено, что существующих методов недостаточно, важен человеческий фактор. This article discusses the impact of the mining industry on the environmental situation ofthe regions of Russia, these include: Kuznetsk, Irkutsk, Kansk-Achinsk, South Yakutia and Donetsk coal basin.Analyzed the effects of mining. Identified methods of dealing with environmental pollution. It was foundthat existing methods is not enough, the human factor is important

Part-time learners in open and distance learning: revisiting the critical importance of choice, flexibility and employability

In this article, we argue that, if open learning seeks to (re)assert a social justice mission, issues of openness and flexibility are more critical than ever. Drawing on qualitative data from a National Union of Students Wales/Open University study, which explored, in the voices of Welsh students, the identity, motivation and barriers faced by part-time distance learners, three key findings emerged. First, the chimaera of ‘choice’ – for part-time distance learners whose personal circumstances prevent any other mode of study; second, the vacuity of policy assertions around ‘flexibility’ in HE – what personalised learning means for part-time distance learners should be contested and re-examined; third, the mantra of ‘employability’ – for part-time distance learners, employability is a conundrum which needs to be understood in a far more inclusively nuanced way. We conclude that the voices of part-time distance learners need to be heard by policy makers and should inform open universities’ continuing efforts to enable vulnerable and marginalised learners to access HE

Influence of participant and reviewer characteristics in application scores for a hematology research training program

The American Society of Hematology Clinical Research Training Institute (CRTI) is a clinical research training program with a competitive application process. The objectives were to compare application scores based on applicant and reviewer sex and underrepresented minority (URM) status. We included applications to CRTI from 2003 to 2019. The application scores were transformed into a scale from 0 to 100 (100 was the strongest). The factors considered were applicant and reviewer sex and URM status. We evaluated whether there was an interaction between the characteristics and time related to application scores. In total, 713 applicants and 2106 reviews were included. There was no significant difference in scores according to applicant sex. URM applicants had significantly worse scores than non-URM applicants (mean [standard error] 67.9 [1.56] vs 71.4 [0.63]; P = .0355). There were significant interactions between reviewer sex and time (P = .0030) and reviewer URM status and time (P = .0424); thus, results were stratified by time. For the 2 earlier time periods, male reviewers gave significantly worse scores than did female reviewers; this difference did not persist for the most recent time period. The URM reviewers did not give significantly different scores across time periods. URM applicants received significantly lower scores than non-URM applicants. The impact of reviewer sex and URM status changed over time. Although male reviewers gave lower scores in the early periods, this effect did not persist in the late period. Efforts are required to mitigate the impact of applicant URM status on application scores
