Testing Hearing: The Making of Modern Aurality argues that the modern cultural practices of hearing and testing have emerged from a long interrelationship. Since the early nineteenth century, auditory test tools (whether organ pipes or electronic tone generators) and the results of hearing tests have fed back into instrument calibration, human training, architecture, and the creation of new musical sounds. Hearing tests received a further boost around 1900 as a result of injury compensation laws and state and professional demands for aptitude testing in schools, conservatories, the military, and other fields. Applied on a large scale, tests of seemingly small measure—of auditory acuity, of hearing range—helped redefine the modern concept of hearing as such. During the twentieth and twenty-first centuries, the epistemic function of hearing expanded. Hearing took on the dual role of test object and test instrument; in the latter case, human hearing became a gauge by which to evaluate or regulate materials, nonhuman organisms, equipment, and technological systems. This book considers both the testing of hearing and testing with hearing to explore the co-creation of modern epistemic and auditory cultures. The book’s twelve contributors trace the design of ever more specific tests for the arts, education and communication, colonial and military applications, and sociopolitical and industrial endeavors. Together, they demonstrate that testing as such became an enduring and wide-ranging cultural technique in the modern period, one that is situated between histories of scientific experimentation and many fields of application.

This introduction frames Testing Hearing: The Making of Modern Aurality by showing how the modern cultural practices of hearing and testing have emerged from a long interrelationship. Since the early nineteenth century, auditory test tools and the results of hearing tests have fed back into instrument calibration, human training, architecture, and new musical sounds. Hearing tests received a further boost around 1900 as a result of injury compensation laws and professional demands for aptitude testing. Applied on a large scale, tests of seemingly small measure—of auditory acuity, of hearing range—helped redefine the modern concept of hearing as such. During the twentieth and twenty-first centuries, the epistemic function of hearing expanded.

In Western Mexico, melon production depends on high-input systems to maximize yield and product quality. Tillage, plasticulture, fumigation with methyl bromide, and fertigation, are the principal management practices in these systems. However, at present several problems has been found: pests as sweetpotato whitefly (Bemisia tabaci Gennadius), aphids (Myzus and Aphis), leafminer (Liryomiza sativae); diseases as Fusarium, Verticilium, and Pseudoperenospora, and weeds demand high pesticide utilization and labor. There is a growing demand for alternative cultural practices, with an emphasis on reducing off-farm input labor and chemicals. Our research is based on use of organic mulches, such as: rice straw, mature maize leaves, banana leaves, sugarcane bagasse, coconut leaves, and living mulches with annual legume cover crop in melons with crop rotation, such as: Canavalia, Stilozobium, Crotalaria, and Clitoria species. Also, inoculations with mycorrhizal arbuscular fungi for honeydew and cantaloupe melon seedlings production are been assayed in greenhouse conditions for a transplant system. The use of life barriers with sorghum, marigold, and other aromatic native plants in conjunction with a colored yellow systems traps for monitoring pests is being studied as well. While that the pest control is based in commercial formulations of Beauveria bassiana for biological control. The first results of this research show that the Glomus intraradices, G. fasciculatum, G. etunicatum, and G. mosseae reached 38.5%, 33.5%, 27.0%, and 31.0% of root infection levels, respectively. Honeydew melons production with rice and corn straw mulches shows an beneficial effect with 113.30 and 111.20 kg/plot of 10 m2 compared with bare soil with 100.20 kg. The proposed system likely also lowers production cost and is applicable to small- and large-scale melon production.

Photographs of the German and Soviet pavilions facing off at the Paris International Exposition in 1937 offer an iconic image of the interwar period, and with good reason. This image captures the interwar period's great conflict of ideologies, the international interconnectedness of the age and the aestheticisation of political and ideological conflict in the age of mass media and mass spectacle. [Figure 1] Last but not least, it captures the importance in the 1930s of what we now call cultural diplomacy. Both pavilions – Germany's, in Albert Speer's neo-classical tower bloc crowned with a giant swastika, and the Soviet Union's, housed in Boris Iofan's forward-thrusting structure topped by Vera Mukhina's monumental sculptural group – represented the outcome of a large-scale collaboration between political leaders and architects, artists, intellectuals and graphic and industrial designers seeking to present their country to foreign visitors in a manner designed to advance the country's interests in the international arena. Each pavilion, that is, made an outreach that was diplomatic – in the sense that it sought to mediate between distinct polities – using means that were cultural – in the sense that they deployed refined aesthetic practices (like the arts and architecture) and in the sense that they highlighted the distinctive features, or ‘culture’, of a particular group (like the German nation or the Soviet state).

AbstractSynthetic sex pheromones released in a loblolly pine, Pinus taeda L. (Pinaceae), seed orchard interfered with the ability of male coneworm moths, Dioryctria Zeller spp. (Lepidoptera: Pyralidae), to locate traps baited with sex pheromones or live females. Pherocon 1C® traps baited with synthetic pheromones or live conspecific females were hung near the center of two 1.2-ha circular plots during emergence of Dioryctria amatella (Hulst), Dioryctria disclusa (Heinrich), and Dioryctria merkeli (Mutuura and Munroe). In a paired design, trap catches for the mating-disruption treatment with synthetic pheromone dispensers consisting of three polyvinyl chloride rods placed in every tree were compared with the control treatment. Treatments were alternated at intervals of 2–3 d. Trap catches of D. amatella were reduced by 91% when plots were treated with 2.5 g/ha of Z-11-hexadencenyl acetate. Catches were reduced by 99.5% for D. disclusa and by 97% for D. merkeli when plots were treated with 12.5 g/ha of Z-9-tetradecenyl acetate, whereas catches of D. amatella were unaffected by this mating-disruption treatment. Daily disappearance of Z-9-tetradecenyl acetate from the dispensers averaged 0.46 g/ha or less. Manually placing dispensers on nylon lines in the tops of trees was an effective method for releasing synthetic Dioryctria pheromones in the orchard. These data suggest it may be feasible to prevent mating of Dioryctria spp. in pine seed orchards by using synthetic pheromones for mating disruption, but large-scale tests will be required to demonstrate cone protection.

BackgroundAustralia is a vast and isolated country and often the only viable option of transporting multiple casualties is using fixed wing aircraft. A number of civilian aeromedical services and the military are responsible for the evacuation of casualties, both nationally and internationally. Due to Australia's increased operational commitments, the military can no longer be expected to provide a rapid aeromedical deployment. This situation, coupled with the limited surge capacity of Australia's civilian fixed wing aeromedical services, highlights the need for Australia to improve preparation and readiness for a large scale civilian aeromedical response.Discussion and ObservationsHistorically, the use of large jets configured for aeromedical use has been exclusively the domain of the military. Yet in recent years the use of large civilian jets configured for aeromedical capability has been suggested as a solution. The purpose of this paper is to explore the role of large civilian jets configured for aeromedical use in the event of a disaster with multiple casualties. This study involved an extensive literature review and an international study tour of aeromedical services that are at the forefront of using large jets in aeromedical evacuation. The findings identified that standard civilian jets can easily be reconfigured for transporting multiple casualties. It is argued that this strategy can be an inexpensive and effective option and should be included in emergency preparedness arrangements. The aim of this paper is to prompt disaster health agencies in Australia to consider the use of a civilian jet system that can be used for a disaster requiring a large scale aeromedical response.

Anyone who watched the televison coverage of, or read about the African famine some years ago could not help but be appalled by the many obstacles erected to impede the progress of getting food to the starving millions in Ethiopia, Somalia and the Sudan. While it is true that the difficult terrain, an inhospitable climate and the lack of rain were partly responsible for the large-scale spread of famine and dearth in the African sub-continent, it is also true that local governments were responsible for creating impediments to the alleviation of mass hunger and starvation. Governments waging war against secessionist regimes and rebel armies used political means—primarily blockades of grain and other foodstuffs—to starve the enemy forces, creating misery among the military as well as civilian populations in the rebel areas.

The seismic behavior and plasticity spreading of a neotype column-slab high pier are researched in this paper. Four scale model tests of a web slab with two boundary columns are carried out under cyclic inelastic lateral displacements simulating seismic response. The test results show that the neotype column-slab high pier has strong and stable bearing capacity, good ductility, and energy dissipation capacity. The experimental values pertaining to the spread of plasticity are derived. An approach for deriving the spread of plasticity analytically is deduced and applied to the four tests. This method accurately assesses a pier’s spread of plasticity for most ductility levels. At nearly all ductility levels, the mean difference between analytical assessments of the spread of plasticity and results from 4 large-scale tests is 12% with a 9% coefficient of variation.

This paper discusses the occupation of Serbia during the First World War by Austro-Hungarian forces. The first partial occupation was short-lived as the Serbian army repelled the aggressors after the Battle of Kolubara in late 1914, but the second one lasted from fall 1915 until the end of the Great War. The Austro-Hungarian occupation zone in Serbia covered the largest share of Serbia?s territory and it was organised in the shape of the Military Governorate on the pattern of Austro-Hungarian occupation of part of Poland. The invaders did not reach a clear decision as to what to do with Serbian territory in post-war period and that gave rise to considerable frictions between Austro-Hungarian and German interests in the Balkans, then between Austrian and Hungarian interests and, finally, between military and civilian authorities within Military Governorate. Throughout the occupation Serbia was exposed to ruthless economic exploitation and her population suffered much both from devastation and from large-scale repression (including deportations, internments and denationalisation) on the part of the occupation regime.

Construction activities entail substantial disturbance of topsoil and vegetative cover. As a result, stormwater runoff and erosion rates are increased significantly. If the soil erosion and subsequently generated sediment are not contained within the site, they would have a negative off-site impact as well as a detrimental influence on the receiving water body. In this study, replicable large-scale tests were used to analyze the ability of products to prevent sediment from exiting the perimeter of a site via sheet flow. The goal of these tests was to compare products to examine how well they retain sediment and how much ponding occurs upstream, as well as other criteria of interest to the Illinois Department of Transportation. The products analyzed were silt fence, woven monofilament geotextile, Filtrexx Siltsoxx, ERTEC ProWattle, triangular silt dike, sediment log, coconut coir log, Siltworm, GeoRidge, straw wattles, and Terra-Tube. Joint tests and vegetated buffer strip tests were also conducted. The duration of each test was 30 minutes, and 116 pounds of clay-loam soil were mixed with water in a 300 gallon tank. The solution was continuously mixed throughout the test. The sediment-water slurry was uniformly discharged over an 8 ft by 20 ft impervious 3:1 slope. The bottom of the slope had a permeable zone (8 ft by 8 ft) constructed from the same soil used in the mixing. The product was installed near the center of this zone. Water samples were collected at 5 minute intervals upstream and downstream of the product. These samples were analyzed for total sediment concentration to determine the effectiveness of each product. The performance of each product was evaluated in terms of sediment removal, ponding, ease of installation, and sustainability.
