Conclusion
No full textThe Conclusion introduces an area of research that the author has not undertaken but which lingers on the edges, occasionally inserting itself for brief moments as other lines of flight are pursued. Looking at three contemporary examples of dance in advertising, it raises the question of bodily labor in relation to concepts of authorship, copyright, and political economy within the advertising industry. The hope is that the chapter points to possible future lines of inquiry and encourages alternative approaches to studying how dancing bodies negotiate consumer culture and neoliberal capitalism. In the end, while there is much the author does not tackle in this project, her goal has been to acknowledge the role advertising potentially plays in the lives of consumers and how dance participates in this relationship.</p
PCC Properties to Support W/C Determination for Durability
No full textThe fresh concrete water-cement ratio (w/c) determination tool is urgently needed for use in the QC/QA process at the job site. Various techniques have been used in the past to determine this parameter. However, many of these techniques can be complicated and time consuming. Furthermore, extensive calibration is often needed to correlate the properties measured by these techniques with w/c. During the course of the present study, the method for the use of the unit weight for the determination of w/c of fresh concrete has been developed and evaluated on both laboratory and field concretes. Additionally, the accuracy of using microwave oven technique for w/c determination reported by previous research was confirmed. Finally, the accuracies of unit weight and microwave oven techniques for the determination of w/c were compared.
The unit weights required for this method have been determined either by using a “zero-air” procedure (ZAP) developed as a part of this study or by using conventional (following AASHTO specifications) methods. The ZAP technique was used to verify the w/c of 58 different laboratory concrete mixes. These verification efforts revealed that the minimum, maximum, standard error, and 95th percentile of the differences (∆w/c) between batched and determined w/c were, respectively, 0.000, 0.042, 0.017, and 0.030. The AASHTO determined unit weight (which also required measurements of the actual air content of concrete) was used to verify the w/c values of an additional set of 57 laboratory mixes. When using the AASHTO unit weights (and air contents) the minimum, maximum, standard error, and 95th percentile of ∆w/c were, respectively, 0.000, 0.075, 0.030, and 0.054. In addition, the AASHTO unit weight method was also used to verify the w/c values of 22 different field mixtures. For this case, the differences (∆w/c) between the design and unit weight-calculated values of w/c were in the range ±0.030 for all but one mixture. Finally, direct comparison of the results from the proposed method with the results obtained from the microwave oven method revealed that the former is faster but slightly less accurate. Specifically, when used on five separate concrete samples, the accuracy of the microwave oven method was 0.010, much smaller than the previously mentioned values of 0.030 (for the ZAP) and 0.054 (for the AASHTO) unit weight methods
Subjectivity and Performative Consumption
No full textChapter Five addresses how television advertising’s dancing bodies engage in the practice of theory, modeling concepts of subjectivity, authenticity, and performance. It examines how dance and choreographic form play a central role in advertising and create a philosophical locus that highlights advertising’s concepts of subjectivity and identity. The chapter argues that in advertising, the liveness, affect, and spectacle of the dancing body informs the construction of identity, directing viewers to see movement as a form of human agency. By highlighting the body’s ability to assume and discard style, dance-in-advertising promotes consumption-as-performance-of-identity. Ultimately, the author argues that dance in advertising models subjectivity and identity as fluid and relational.</p
Commercials as Discursive Assemblages
No full textChapter Two demonstrates how commercials employ genre-specific codes and conventions to operate as discursive assemblages. The author adopts Grossberg’s concept of cultural formations as a model for analyzing dance in advertising. Through close readings of several commercials created for US companies produced between 1948 and 2012, the chapter offers an historicized reading of the strategic intersections between dance, television, film, and advertising within commercials to produce a form of marketing that simultaneously reinforces and destabilizes disciplinary boundaries. Several concepts central to the larger project are introduced here, including liveness, advertising positioning strategies, direct address and hailing, montage, and film musical conventions. While the study focuses on an analysis of the history and conventions of dance-in-advertising in the United States during the mid-to-late twentieth and early twenty-first centuries, it also includes examples of commercials created to advertise US products in foreign markets.</p
J Clean Prod
No full textWorkers and fence-line communities have been the first to benefit from the substantial reductions in toxic chemical use and byproducts in industrial production resulting from the Massachusetts Toxics Use Reduction Act (TURA). As TURA motivates reformulation of products as well as retooling of production processes, benefits could extend more broadly to large-scale reductions in everyday exposures for the general population. Household exposure studies, including those conducted by Silent Spring Institute, show that people are exposed to complex mixtures of indoor toxics from building materials and a myriad of consumer products. Pollutants in homes are likely to have multiple health effects because many are classified as endocrine disrupting compounds (EDCs), with the ability to interfere with the body's hormone system. Product-related EDCs measured in homes include phthalates, halogenated flame retardants, and alkylphenols. Silent Spring Institute's chemical analysis of personal care and cleaning products confirms many are potential sources of EDCs, highlighting the need for a more comprehensive toxics use reduction (TUR) approach to reduce those exposures. Toxics use reduction targeted at EDCs in consumer products has the potential to substantially reduce occupational and residential exposures. The lessons that have emerged from household exposure research can inform improved chemicals management policies at the state and national levels, leading to safer products and widespread health and environmental benefits.R25 ES013258-04S1/ES/NIEHS NIH HHSUnited States/R25 ES013258-02/ES/NIEHS NIH HHSUnited States/R25 ES013258-03/ES/NIEHS NIH HHSUnited States/R25 ES013258/ES/NIEHS NIH HHSUnited States/R01 EH000632/EH/NCEH CDC HHSUnited States/R25 ES013258-01/ES/NIEHS NIH HHSUnited States/R25 ES013258-04/ES/NIEHS NIH HHSUnited States/R25 ES013258-04S2/ES/NIEHS NIH HHSUnited States
Contact urticaria to giraffe hair
No full textBackground: Immediate-type hypersensitivity to animal proteins is a common problem in people occupationally exposed to animals. Methods: A 19-year-old female working as a voluntary zookeeper in her off-time suffered from hives on her forearms following contact to the fur of a giraffe. For diagnostic evaluation, skin prick tests, assessment of specific serum IgE antibodies, and basophil activation tests were performed. Results: Skin prick tests with a standard series of common aeroallergens were positive for various pollens. Prick testing with native materials was positive for extracts of hair from two different giraffe subspecies in the patient, but not in control subjects. By CAP-FEIA, no specific serum IgE antibodies to dander of a large variety of animals were found in the patient. In the basophil activation test, expression of the activation marker CD63 was induced by extract of giraffe hair on the cells from the patient, but not on those from unaffected controls. Conclusions: This patient suffers from an `exotic' immediate-type contact allergy to giraffe hair. Copyright (C) 2005 S. Karger AG, Basel

Search for Pauli exclusion principle violating atomic transitions and electron decay with a p-type point contact germanium detector
No full textA search for Pauli-exclusion-principle-violating K-alpha electron transitions was performed using 89.5 kg-d of data collected with a p-type point contact high-purity germanium detector operated at the Kimballton Underground Research Facility. A lower limit on the transition lifetime of 5.8x10^30 seconds at 90% C.L. was set by looking for a peak at 10.6 keV resulting from the x-ray and Auger electrons present following the transition. A similar analysis was done to look for the decay of atomic K-shell electrons into neutrinos, resulting in a lower limit of 6.8x10^30 seconds at 90 C.L. It is estimated that the MAJORANA DEMONSTRATOR, a 44 kg array of p-type point contact detectors that will search for the neutrinoless double-beta decay of 76-Ge, could improve upon these exclusion limits by an order of magnitude after three years of operation.

Thermoregulatory effects of caffeine ingestion during rest and exercise in men
No full textBody temperatures and thermoregulatory responses were measured at rest and during submaximal exercise under normal ambient conditions in 11 aerobically-conditioned men (age = 29.2 +/- 6.2 yr, VO2(max) = 3.73 +/- 0.46 min(sup -1), relative body fat = 12.3 +/- 3.7 percent, mean +/- SD) with (CT) and without (NCT) the ingestion of 10 mg of caffeine per kg of body weight. Oxygen uptake (VO2), heart rate (HR), and rectal (T(sub re)) and mean skin (T-bar(sub sk)) temperatures were recorded for 100 minutes starting one minute after ingestion of caffeine or a placebo. Data were collected throughout 30 minutes of rest (sitting) and the following 70 minutes of sitting leg ergometer exercise using the same constant load (1,088 +/- 153 kgm/min) in both NCT and CT. The load resulted in a mean relative exercise intensity equal to approximately 68 percent of VO2(sub max). Skin heat conductance (H(sub sk)) and sweat rate were calculated. Two-way analysis of covariance revealed no significant (P greater than 0.05) differences between NCT and CT in VO2, HR, T(sub re), T-bar(sub sk), or H(sub sk). A dependent t-test indicated no significant difference between NCT and CT in sweat rate. Thus, a high level of caffeine ingestion has no detrimental effects on body temperatures and thermoregulatory responses during moderately heavy exercise in normal ambient conditions
