Judging Covers

Cover versions form a loose but identifiable category of tracks and performances. We distinguish four kinds of covers and argue that they mark important differences in the modes of evaluation that are possible or appropriate for each: mimic covers, which aim merely to echo the canonical track; rendition covers, which change the sound of the canonical track; transformative covers, which diverge so much as to instantiate a distinct, albeit derivative song; and referential covers, which not only instantiate a distinct song, but for which the new song is in part about the original song. In order to allow for the very possibility of transformative and referential covers, we argue that a cover is characterized by relation to a canonical track rather than merely by being a new instance of a song that had been recorded previousl

DRASTIC Hydrogeologic Settings Modified for Fractured Till: Part 1. Theory

Author Institution: Bennett & Williams Environmental Consultants Inc., Columbus, OHAuthor Institution: Dept. of Food, Agricultural and Biological Engineering, The Ohio State University, Columbus, OHAuthor Institution: Ohio Dept. of Natural Resources, Division of Water, Columbus, OHAuthor Institution: Bennett & Williams Environmental Consultants Inc., Columbus, OHThe ground water vulnerability assessment model, DRASTIC, has been modified to better evaluate the effect of fractured till. In the mid-1980s, the Ohio Department of Natural Resources (ODNR) Division of Water began statewide, county-by-county mapping of the potential for ground water pollution. Eventually it was recognized that the original DRASTIC methodology needed to be modified to incorporate the concept of double-block porosity and preferential flow through Ohio’s fractured glacial tills. Glacial till was eventually recognized as a unique vadose zone media, and different ratings were assigned to the various till lithologies. It was determined that thin, weathered, highly-fractured tills should be more highly rated by increasing the rating of “R” Net Recharge and “I” Impact of the vadose zone media, where appropriate. In rare instances, the ratings of very thin soils (“S” Soil media) were modified to reflect the nature of underlying parent materials. In contrast, extremely thick sequences of unweathered till were given lower ratings for “R” Net Recharge and “I” Impact of the vadose zone media. DRASTIC maps have been completed for 76% of the 88 counties in Ohio. With the advent of Geographic Information Systems (GIS) applications, compiling a county DRASTIC map has become faster, and publication costs have been significantly reduced. GIS provides the tools to review and quickly modify historical mapping efforts that predate the fracture modification. This paper reviews the history of DRASTIC mapping in Ohio, presents the theory of modifications for fractures, and includes some discussion of Ohio regulatory applications

Effectiveness of circuit interval training and physiotherapy health education on anthropometric measurements and quality of life among obese women with polycystic ovary syndrome- a randomised controlled trial

Background: The objective was to assess the effectiveness of circuit interval training and physiotherapy health education on anthropometric measurements and quality of life (QOL) among obese women with PCOS. Methods: The study is a parallel group randomised controlled trial   among 40 obese women diagnosed with PCOS based on Rotterdam criteria and conducted in obstetrics and gynaecology Physiotherapy centre, IGMC&RI, Puducherry. Allocation of participants to group A and group B done using permutated block randomization by an independent physiotherapist. Group A(n=20) received the conventional treatment and Group B (n=20) received the circuit interval training for 6 weeks. Results: The outcome values obtained were calculated by the software SPSS 26. The power of the study is 80%. P<0.05 was considered a significant difference and 95% confidence. There was a significant improvement in the pre and post-test values of anthropometric measurements (BMI and WHR) within the experimental group. The minimal clinically important difference (MCID) of 1.03 points in BMI, 0.019 in WHR, and 0.018 in WHtR, which was higher than the MCID of the control group was observed between the groups. The results show that circuit interval training is effective in improving the anthropometric measurements and quality of life obesity was found to have a negative correlation with the quality of life, implying that increased weight reduces the quality of life in PCOS women. Conclusions: Circuit interval training along with physiotherapy health education, has a positive impact on improving anthropometric measurements such as BMI, waist circumference, and metabolic parameters over time

Unpolarized structure functions at Jefferson Lab

Over the past decade measurements of unpolarized structure functions at Jefferson Lab with unprecedented precision have significantly advanced our knowledge of nucleon structure. These have for the first time allowed quantitative tests of the phenomenon of quark-hadron duality, and provided a deeper understanding of the transition from hadron to quark degrees of freedom in inclusive scattering. Dedicated Rosenbluth-separation experiments have yielded high-precision transverse and longitudinal structure functions in regions previously unexplored, and new techniques have enabled the first glimpses of the structure of the free neutron, without contamination from nuclear effects.Comment: 21 pages, 9 figures; typo in Eq.

Classical Cepheid Pulsation Models: IX. New Input Physics

We constructed several sequences of classical Cepheid envelope models at solar chemical composition ($Y=0.28, Z=0.02$) to investigate the dependence of the pulsation properties predicted by linear and nonlinear hydrodynamical models on input physics. To study the dependence on the equation of state (EOS) we performed several numerical experiments by using the simplified analytical EOS originally developed by Stellingwerf and the recent analytical EOS developed by Irwin. Current findings suggest that the pulsation amplitudes as well as the topology of the instability strip marginally depend on the adopted EOS. We also investigated the dependence of observables predicted by theoretical models on the mass-luminosity (ML) relation and on the spatial resolution across the Hydrogen and the Helium partial ionization regions. We found that nonlinear models are marginally affected by these physical and numerical assumptions. In particular, the difference between new and old models in the location as well as in the temperature width of the instability strip is on average smaller than 200 K. However, the spatial resolution somehow affects the pulsation properties. The new fine models predict a period at the center of the Hertzsprung Progression ($P_{HP}=9.65$$-$9.84 days) that reasonably agree with empirical data based on light curves ($P_{HP}=10.0\pm 0.5$ days; \citealt{mbm92}) and on radial velocity curves ($P_{HP}=9.95\pm 0.05$ days; \citealt{mall00}), and improve previous predictions by Bono, Castellani, and Marconi (2000, hereinafter BCM00).Comment: 35 pages, 7 figures.

Double radiative pion capture on hydrogen and deuterium and the nucleon's pion cloud

We report measurements of double radiative capture in pionic hydrogen and pionic deuterium. The measurements were performed with the RMC spectrometer at the TRIUMF cyclotron by recording photon pairs from pion stops in liquid hydrogen and deuterium targets. We obtained absolute branching ratios of $(3.02 \pm 0.27 (stat.) \pm 0.31 (syst.)) \times 10^{-5}$ for hydrogen and $(1.42 \pm ^{0.09}_{0.12} (stat.) \pm 0.11 (syst.)) \times 10^{-5}$ for deuterium, and relative branching ratios of double radiative capture to single radiative capture of $(7.68 \pm 0.69(stat.) \pm 0.79(syst.)) \times 10^{-5}$ for hydrogen and $(5.44 \pm^{0.34}_{0.46}(stat.) \pm 0.42(syst.)) \times 10^{-5}$ for deuterium. For hydrogen, the measured branching ratio and photon energy-angle distributions are in fair agreement with a reaction mechanism involving the annihilation of the incident $\pi^-$ on the $\pi^+$ cloud of the target proton. For deuterium, the measured branching ratio and energy-angle distributions are qualitatively consistent with simple arguments for the expected role of the spectator neutron. A comparison between our hydrogen and deuterium data and earlier beryllium and carbon data reveals substantial changes in the relative branching ratios and the energy-angle distributions and is in agreement with the expected evolution of the reaction dynamics from an annihilation process in S-state capture to a bremsstrahlung process in P-state capture. Lastly, we comment on the relevance of the double radiative process to the investigation of the charged pion polarizability and the in-medium pion field.Comment: 44 pages, 7 tables, 13 figures, submitted to Phys.

DRASTIC Hydrogeologic Settings Modified for Fractured Till: Part 2. Field Observations

Author Institution: Bennett & Williams Environmental Consultants Inc., Columbus, OHAuthor Institution: Dept. of Food, Agricultural and Biological Engineering, The Ohio State University, Columbus, OHAuthor Institution: Ohio Dept. of Natural Resources, Division of Water, Columbus, OHAuthor Institution: USDA-Natural Resources Conservation Service, Columbus, OHAuthor Institution: Bennett & Williams Environmental Consultants Inc., Columbus, OHDeveloped as a companion paper to "DRASTIC Hydrogeologic Settings Modified for Fractured Till: Part 1. Theory," twenty-one field sites around glaciated Ohio were visited to determine if fractures were present in the soils and underlying parent materials at each location. Four sites were featured with indepth discussions. In all, 23 of the original 95 fractured soils identified in Tornes and others (2000) were confirmed in the field and four new soils were added to the list: Amanda, Avonburg, Blanchester, and Clermont. Settings were grouped by common glacial and soils characteristics where they were linked to predict similar conditions over a wider ranging area. Modifications to their site specific DRASTIC ratings can be extrapolated to the larger geologic regions. All 21 sites were evaluated for their DRASTIC settings and new Ground Water Pollution Potential numbers were assigned where necessary. Modification of the DRASTIC mapping method has made the Ohio Ground Water Pollution Potential mapping program more protective of Ohio's ground water supplies. DRASTIC mapping efforts can play an important role in not only statewide but also local ground water pollution protection efforts

Observation of double radiative capture on pionic hydrogen

We report the first observation of double radiative capture on pionic hydrogen. The experiment was conducted at the TRIUMF cyclotron using the RMC spectrometer, and detected $\gamma$--ray coincidences following $\pi^-$ stops in liquid hydrogen. We found the branching ratio for double radiative capture to be $(3.05 \pm 0.27(stat.) \pm 0.31(syst.)) \times 10^{-5}$. The measured branching ratio and angle-energy distributions support the theoretical prediction of a dominant contribution from the $\pi \pi \to \gamma \gamma$ annihilation mechanism.Comment: 4 Pages, 4 Figures. accepted for publication in Phys.

Art concept pluralism

There is a long tradition of trying to analyze art either by providing a definition (essentialism) or by tracing its contours as an indefinable, open concept (antiessentialism). Both art essentialists and art anti-essentialists share an implicit assumption of art concept monism. We argue that this is a mistake. Species concept pluralism, a well-explored position in philosophy of biology, provides a model for art concept pluralism. We explore the conditions under which concept pluralism is appropriate, and we argue that they obtain for art. Art concept pluralism allows us to recognize that different art concepts are useful for different purposes, and what had been feuding definitions can be seen as characterizations of specific art concepts
