Deconstructing Deleuze and Guattari’s A Thousand Plateaus for Music Education
Authors: Jorgensen Estelle R. , Yob Iris M. 
Published: July 2013

Abstract
In this essay, Deleuze and Guattari’s ideas as discussed in their book, A Thousand Plateaus: Capitalism and Schizophrenia, are critically examined with a view to determining the merits of their ideas as a basis for a philosophy of music education. Three principal questions are at the heart of this analysis: What are Deleuze and Guattari asking us to believe? What is our assessment of their contributions and detractions? What are the implications of our analysis for music education? Our approach is dialogical in juxtaposing an analysis of their ideas construed more broadly with an examination of selected metaphors that they use, and thereby combining literal and figurative thought. While their thinking constitutes a limited and flawed basis for a philosophy of music education, they prompt insights that are valuable for music education thought and practice.
Dance as Portrayed in the Media
Authors: Misirhiralall Sabrina D. 
Published: July 2013

Abstract
The portrayal of dance in the media is of a current educational interest for dancers, dance educators, as well as the viewers of the performance. I seek to determine how knowledge construction of dance develops within the public sphere. With the knowledge construction of dance epistemologically and ethically in mind, this research focuses on the way the ideology of written language is used to describe dance in the western world in the media. The media is a form of literacy that helps the public sphere access knowledge and build their knowledge of dance. Yet, the public sphere has the potential to influence the media’s knowledge construction of dance. This article attempts to answer a question that many dancers and non-dancers have. What is dance according to the media? How does the written word portray dance in the media? To answer these questions, the research focuses on the role that the discourse of dance in the media plays in the public sphere’s knowledge construction of dance. This is important to study because the public sphere’s meaning of dance will determine whether or not dance education is promoted or banned in schools and in society.

ObjectiveTo identify psychological profiles in persons with knee osteoarthritis (OA) and to determine the relationship between these profiles and specific pain and sensory characteristics, including temporal summation and conditioned pain modulation.MethodsIndividuals with knee OA (n = 194) completed psychological, health, and sensory assessments. Hierarchical cluster analysis was used to derive psychological profiles that were compared across several clinical pain/disability and experimental pain responses.ResultsCluster 1 had high optimism with low negative affect, pain vigilance, anger, and depression, along with the lowest self‐reported pain/disability and the lowest sensitivity to mechanical, pressure, and thermal pain (P < 0.01 for all). Cluster 2 had low positive affect with high somatic reactivity, while cluster 3 showed high pain vigilance with low optimism. Clusters 2 and 3 had intermediate levels of self‐reported pain/disability and cluster 3 experienced central sensitization to mechanical stimuli. Participants in cluster 3 also displayed significant pain facilitation (P < 0.05). Cluster 4 exhibited the highest pain vigilance, reactivity, negative affect, anger, and depression. These individuals experienced the highest self‐reported pain/disability, including widespread pain (P < 0.001 for all). Cluster 4 was most sensitive to mechanical, pressure, and thermal stimuli, and showed significant central sensitization to mechanical and thermal stimuli (P < 0.001 for all).ConclusionOur findings demonstrate the existence of homogeneous psychological profiles displaying unique sets of clinical and somatosensory characteristics. Multidisciplinary treatment approaches consistent with the biopsychosocial model of pain should provide significant advantages if targeted to profiles such as those in our OA sample.

ObjectiveTo describe the exercise/physical activity and weight management efforts of Canadians with self‐reported arthritis, to examine factors associated with their engagement in these strategies to help manage their arthritis, and to explore reasons for lack of engagement.MethodsData were from the arthritis component of the 2009 Survey on Living with Chronic Diseases in Canada. The responses (78% response rate; n = 4,565) were weighted to be representative of Canadians (ages ≥20 years) with arthritis. Logistic regression analyses were used to examine factors associated with engaging in exercise/physical activity and weight control/loss (among overweight/obese respondents) for arthritis management purposes.ResultsIndividuals with arthritis were mostly women (63%), ages ≥45 years (89%), overweight/obese (67%), married (68%), and white (87%), with postsecondary education (69%). Sixty‐three percent were exercising and of those who were overweight or obese, 68% were trying to control/lose weight; only 46% were engaged in both. Having received a clinical recommendation was the factor most strongly associated with engaging in exercise/physical activity and/or controlling/losing weight. The most common reason for not exercising was a coexisting health condition/problem (22%), while the most common reason for not controlling/losing weight among those who were overweight/obese was that it was felt not to be necessary (51%).ConclusionThe provision of clinical recommendations from a health professional, providing advice on safe and suitable exercises/physical activities, as well as addressing misperceptions of the need to lose weight among the overweight/obese, may facilitate engagement in these health behaviors and ultimately reduce the consequences of arthritis.

Published: July 2013

ObjectiveTo examine the associations of foot posture and foot function to foot pain.MethodsData were collected on 3,378 members of the Framingham Study cohort who completed foot examinations in 2002–2008. Foot pain (generalized and at 6 locations) was based on the response to the following question: “On most days, do you have pain, aching or stiffness in either foot?” Foot posture was categorized as normal, planus, or cavus using static pressure measurements of the arch index. Foot function was categorized as normal, pronated, or supinated using the center of pressure excursion index from dynamic pressure measurements. Sex‐specific multivariate logistic regression models were used to examine the effect of foot posture and function on generalized and location‐specific foot pain, adjusting for age and weight.ResultsPlanus foot posture was significantly associated with an increased likelihood of arch pain in men (odds ratio [OR] 1.38, 95% confidence interval [95% CI] 1.01–1.90), while cavus foot posture was protective against ball of foot pain (OR 0.74, 95% CI 0.55–1.00) and arch pain (OR 0.64, 95% CI 0.48–0.85) in women. Pronated foot function was significantly associated with an increased likelihood of generalized foot pain (OR 1.28, 95% CI 1.04–1.56) and heel pain (OR 1.54, 95% CI 1.04–2.27) in men, while supinated foot function was protective against hindfoot pain in women (OR 0.74, 95% CI 0.55–1.00).ConclusionPlanus foot posture and pronated foot function are associated with foot symptoms. Interventions that modify abnormal foot posture and function may therefore have a role in the prevention and treatment of foot pain.
Ruthenium Oxide Hydrogen Evolution Catalysis on Composite Cuprous Oxide Water‐Splitting Photocathodes

Published: July 2013

Photocathodes based on cuprous oxide (Cu2O) are promising materials for large scale and widespread solar fuel generation due to the abundance of copper, suitable bandgap, and favorable band alignments for reducing water and carbon dioxide. A protective overlayer is required to stabilize the Cu2O in aqueous media under illumination, and the interface between this overlayer and the catalyst nanoparticles was previously identified as a key source of instability. Here, the properties of the protective titanium dioxide overlayer of composite cuprous oxide photocathodes are further investigated, as well as an oxide‐based hydrogen evolution catalyst, ruthenium oxide (RuO2). The RuO2‐catalyzed photoelectrodes exhibit much improved stability versus platinum nanoparticles, with 94% stability after 8 h of light‐chopping chronoamperometry. Faradaic efficiencies of ∼100% are obtained as determined by measurement of the evolved hydrogen gas. The sustained photocurrents of close to 5 mA cm−2 obtained with this electrode during the chronoamperometry measurement (at 0 V vs. the reversible hydrogen electrode, pH 5, and simulated 1 sun illumination) would correspond to greater than 6% solar‐to‐hydrogen conversion efficiency in a tandem photoelectrochemical cell, where the bias is provided by a photovoltaic device such as a dye‐sensitized solar cell.

Published: July 2013

AbstractBackgroundDrywall installers are at high‐risk of work‐related injury. Comprehensive descriptive epidemiology of injuries among drywall installers, particularly over time, is lacking.MethodsWe identified worker‐hours and reported and accepted workers' compensation (WC) claims for a 20‐year (1989–2008) cohort of 24,830 Washington State union carpenters. Stratified by predominant type of work (drywall installation, other carpentry), work‐related injury rates were examined over calendar time and by worker characteristics. Expert interviews provided contextual details.ResultsDrywall installers' injury rates, higher than those of other carpenters, declined substantially over this period by 73.6%. Common injury mechanisms were struck by/against, overexertion and falls. Drywall material was considered a contributing factor in 19.7% of injuries. One‐third of these drywall material‐related injuries resulted in paid lost time, compared to 19.4% of injuries from other sources. Rates of injury were particularly high among workers with 2 to <4 years in the union. Notable declines over time in rates of overexertion injury in which drywall material was a contributing factor were still observed after controlling for secular temporal trends. Experts highlighted changes over the past 20 years that improved both work safety and, in some cases, production.ConclusionsDeclines in drywall installers' injury rates over time likely reflect, in part, enhanced workplace safety, including efforts to reduce overexertion hazards associated with handling drywall. Continued injury prevention efforts are needed, particularly for less tenured workers. Given the potential for under‐reporting to WC, additional sources of health outcomes data may provide a more complete picture of workers' health. Am. J. Ind.

Published: July 2013

AbstractBackgroundOur objective was to study the associations between organizational workplace characteristics (OC) reported by call‐center (CC) managers and workplace stressors reported by call‐handlers.MethodsThe managers of 107 CCs were interviewed by their occupational physicians using a questionnaire designed to specifically explore OC in the CCs. Four thousand two call‐handlers from these CCs completed a self‐report questionnaire including the Karasek and Siegrist work stressor questionnaires and two specific items on other workplace stressors.ResultsAround one‐third of the OC examined were associated with the demand/control ratio, the perception of demanding work and ethical conflicts, however, far fewer OC were associated with the effort/reward ratio. Most OC were associated with higher levels of job stressors. Some had strong, systematic negative associations with stressors (e.g., highly formatted instructions for the client relationship).ConclusionsThese findings could help in targeting job stressor prevention and health improvement strategies in CCs.

Aspirin desensitization for aspirin‐exacerbated respiratory disease (Samter's Triad): a systematic review of the literature
Authors: Xu Jason J. , Sowerby Leigh , Rotenberg Brian W. 
Published: July 2013

ObjectivesTo critically review the current literature regarding aspirin desensitization treatment for nasal polyposis in patients with Aspirin‐Exacerbated Respiratory Disease (AERD).Study DesignSystematic review of the literature.MethodsAll English literature published between January 1995 and February 2013 reporting specifically nasal outcomes following aspirin desensitization in AERD patients were eligible for inclusion. Exclusion criteria were non‐investigative, non‐human, and ex‐vivo studies. Studies were categorized by level of evidence and evaluated for quality using the Downs and Black scale.ResultsA total of 614 citations were retrieved and eleven studies met the criteria for analysis. Outcome measurements included self‐reported symptom scores, amount of corticosteroid use, rate of revision surgery, and quantitative measurements such as rhinomanometry. Overall, most studies reported a significant improvement in symptom scores, decrease in corticosteroid use, and decrease in revision surgery. A few studies showed promising results with quantitative outcomes. However, most studies were of Level 2 evidence with small samples sizes. Rates of adverse events ranged from 12.5% to 23%.ConclusionsUnlike traditional treatments for nasal polyposis, aspirin desensitization targets AERD etiology rather than phenotype and can be an effective therapeutic option. While the current literature shows encouraging results, additional studies are needed to better define clinical benefits.
Demonstrating the mechanism and efficacy of water‐induced shape memory and the influence of water on the thermal properties of oriented poly(d,l‐lactide)

Published: July 2013

ABSTRACTAchieving water‐induced shape‐memory property in poly(D,L‐lactide) (PDLLA), generated by means of advanced processing methods, opens possibilities to develop novel bioresorbable medical devices with shape‐memory properties activated by the human body without external heat. The main phenomena that affect the molecular movements that enable the water‐induced shape‐memory effect in an oriented PDLLA in an aqueous environment at physiological temperature are related to the water driven disruption of the intermolecular dipole‐dipole and/or hydrogen bonding of the oriented PDLLA chains and the subsequent decrease of the glass transition temperature (Tg) to the range of physiological temperature. The diffused water in the polymer matrix decreased the energy needed to finish the glass transition process explaining the higher shape‐recovery rate of the γ‐irradiated PDLLA with respect to the non‐γ‐irradiated PDLLA in an aqueous environment at physiological temperatures. The water‐induced decrease in the Tg was thermally reversible. The efficacy of the generated shape‐memory was tested with PDLLA shape‐memory nails in a pullout test, in which the pullout force of the PDLLA nails increased 360% during a seven day test period in vitro at 37°C. © 2013 Wiley Periodicals, Inc.

Published: July 2013

ABSTRACTThe hydrolytic degradation and corresponding content release of capsules made of poly(d,l‐lactic‐co‐glycolic acid) (PLGA) strongly depends on the composition and material properties of the initially applied copolymer. Consecutive or simultaneous release from capsule batches of combinable material compositions, therefore, offers high control over the bioavailability of an encapsulated drug. The keynote of this study was the creation of a superordinated database that addressed the correlation between the release kinetics of filling agents with different molecular weights from PLGA capsules of alternating composition. Fluorescein isothiocyanate (FITC)–dextran (with molecular weights of 4, 40, and 2000 kDa) was chosen as a model analyte, whereas the copolymers were taken from various 50:50 PLGA, 75:25 PLGA, and polylactide blends. With reference to recent publications, the capsule properties, such as the size, morphology, and encapsulation efficiency, were further modified during production. Hence, uniform microdisperse and polydisperse submicrometer nanocapsules were prepared by two different water‐in‐oil‐in‐water emulsification techniques, and additional effects on the size and morphology were achieved by capsule solidification in two different sodium salt buffers. The qualitative and quantitative examination of the physical capsule properties was performed by confocal laser scanning microscopy, scanning electron microscopy, and Coulter counting techniques to evaluate the capsule size distribution and the morphological appearance of the different batches. The corresponding agent release was quantified by fluorescence measurement of the FITC–dextran in the incubation media and by the direct measurement of the capsule brightness via fluorescence microscopy. In summary, the observed agent release showed a highly controllable flexibility depending on the PLGA blends, preparation methods, and molecular weight of the used filling substances. © 2013 Wiley Periodicals, Inc.

ABSTRACTSemi‐interpenetrating polymer networks (S‐IPNs) were prepared by the reactions of hydroxyl‐terminated four‐armed, star‐shaped ε‐caprolactone oligomers with degrees of polymerization per one oligocaprolactone chain (ns) of 3, 5, and 10 and 2,4‐tolylene diisocyanate (TDI) in the presence of poly(ε‐caprolactone) (PCL). In the dynamic mechanical analysis of the S‐IPN [2,4‐tolylene diisocyanate bridged hydroxyl‐terminated four‐armed, star‐shaped ε‐caprolactone oligomer (TH4CLO)/PCL], only one tan δ peak was observed; its temperature increased with increasing TH4CLO content and with decreasing n value. Differential scanning calorimetric analyses of the TH4CLOs and TH4CLO/PCLs revealed that the TH4CLOs with ns of 3 and 5 were amorphous, whereas TH4CLO with an n of 10 was semicrystalline and that the crystallization of the PCL chain for TH4CLO/PCLs was more strongly disturbed with increasing TH4CLO content and decreasing n value. Although the tensile strength, modulus, and elongation at break of TH4CLO were much lower than those of PCL, those values increased with the n value. Although the tensile strength and modulus of the TH4CLO/PCLs decreased with increasing TH4CLO content, TH4CLO (n = 3)/PCL 50/50 showed the highest elongation at break (314%) among the S‐IPNs because of the suppression of crystallization of the polycaprolactone chain. © 2013 Wiley Periodicals, Inc.

Published: July 2013

ABSTRACTThis study evaluated the effect of scaffold processing methods on viscoelastic properties of polycaprolactone (PCL), a frequently explored biomaterial in tissue engineering. 80 kDa and 45 kDa PCL scaffolds were synthesized using salt leaching and electrospinning techniques. Also, films were formed by air drying. Scanning electron microscopy analysis confirmed that salt leached scaffolds had open pore architecture and electrospun scaffolds had randomly distributed uniform fibers. Using the tensile test results in phosphate buffered saline (pH=7.4) and 37° C, ramp‐hold tests were performed for five stages by setting the strain rate to be 1%s−1for 2 s followed by 58 s of hold. Also, tests were performed at various strain rates and total strain. Salt leached scaffolds of same MW showed less relaxation in each stage relative to electrospun scaffolds. 45 kDa salt leached scaffolds relaxed more than 80 kDa scaffolds. Stress accumulated in each stage was more in films than in scaffolds. However, relaxation function appeared similar between films and electrospun fibers. Strain rate and amount of applied strain had significant effect on relaxation characteristics; 0.6%s−1strain rate had higher accumulated stress than 1%s−1and 3%s−1. Increased amount of loading had significant effect in the first stage with repetitive relaxation characteristics in subsequent stages. SEM analysis of tested samples showed no change in the microstructure with the exception of a few locations where pores oriented in the direction of the pull. In summary, viscoelastic characteristics vary based on the type of scaffold processing used, despite use of the same polymer. © 2013 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 130: 4237–4244, 2013
