Reply to comment by B. Andreotti et al. on "Solving the mystery of booming sand dunes"

This reply addresses three main issues raised in the comment of Andreotti et al. [2008]. First, the turning of ray paths in a granular material does not preclude the propagation of body waves and the resonance condition described by Vriend et al. [2007]. The waveguide model still holds in the dune for the observed velocities, even with a velocity increase with depth as implied by Andreotti et al. [2008]. Secondly, the method of initiation of spontaneous avalanching does not influence the booming frequency. The frequency is independent of the source once sustained booming starts; it depends on the subsurface structure of the dune. Thirdly, if all data points from Vriend et al. [2007] are included in the analysis (and not an average or selection), no correlation is observed between the sustained booming frequency and average particle diameter

Solving the mystery of booming sand dunes

Desert booming can be heard after a natural slumping event or during a sand avalanche generated by humans sliding down the slip face of a large dune. The sound is remarkable because it is composed of one dominant audible frequency (70 to 105 Hz) plus several higher harmonics. This study challenges earlier reports that the dunes’ frequency is a function of average grain size by demonstrating through extensive field measurements that the booming frequency results from a natural waveguide associated with the dune. The booming frequency is fixed by the depth of the surficial layer of dry loose sand that is sandwiched between two regions of higher compressional body wave velocity. This letter presents measurements of the booming frequencies, compressional wave velocities, depth of surficial layer, along with an analytical prediction of the frequency based on constructive interference of propagating waves generated by avalanching along the dune surface

Profil psychosocial des femmes qui offrent des services sexuels au Bas-Saint-Laurent

Avant-propos: La présente étude est issue de l’Entente sur l’égalité entre les femmes et les hommes au Bas-Saint-Laurent 2011-2015, dont les partenaires sont le Ministère de la Culture, des Communications et de la Condition féminine (MCCCF), le Ministère des Affaires municipales, des Régions et de l'Occupation du territoire (MAMROT), l’Agence de la santé et des services sociaux du Bas-Saint-Laurent (ASSS du BSL), la Conférence régionale des éluEs du Bas-Saint-Laurent (CRÉBSL), la Commission Jeunesse (CJ) et la Table de concertation des groupes de femmes du Bas-Saint-Laurent (TCGFBSL). La présente étude s’inscrit dans les travaux de recherche de l’Étude sur le Développement et le Comportement Sexuel des personnes qui offrent des services sexuels et des personnes qui n’offrent pas de services sexuels (ÉDECS), menée à l’Université du Québec à Chicoutimi, en collaboration avec l’Université de Montréal. L’ÉDECS vise à évaluer le profil psychosocial, les besoins et les risques de victimisation de personnes travaillant dans les différentes catégories de services sexuels de même que les facteurs d’entrée et de maintien dans l’offre de services sexuels

Inner-City Education: Are We Failing?

These collected papers and reports; many taken from the Professional Education Seminar at the University of Northern Iowa; concentrate on the failure of inner-city education. A number of essays attempt to analyze the role of teachers; administrators; and communities in the failure of inner-city education. Also; there are several field reports on specific cities. Teacher preparation for working with disadvantaged black students in an urban setting is discussed at length. (Editor/JW

Infrared reflectance measurements of Missouri waters for water quality applications

Students supported: 2 studentsThe relative specular reflectance of laboratory solutions of 3.0 M Sulfuric Acid and 0.5 M Sodium Nitrate was measured in the 2.0 - 20-[mu]m wavelength region of the infrared. The relative specular reflectance of natural samples of (1) acid mine drainage taken from a ditch leading from the Peabody Mark Twain Mine to Hinkson Creek; (2) surface water runoff from an agricultural test plot which had received a 314 lb/acre application of nitrate fertilizer; and (3) an oil sample from the Mexico, Missouri oil release into the Salt River was measured in the same spectral region. The data was collected using a Perkin Elmer E-14 spectrophotometer and a reflectometer consisting of a Cassegrain unit which collimated the radiant flux to about 18 mrad divergence, a sample holder and a Cassegrain condenser for focusing the radiant flux, reflected by the sample, onto the entrance slit of the monochromator. The angle of incidence was 70 degrees. The index of refraction, extinction coefficient and phase difference spectrum throughout the 2-20-[mu]m wavelength region was determined for the mine drainage, fuel oil, sulfuric acid, sodium nitrate and nitrate runoff samples using the relative reflectance measurements, the optical constants of distilled water and an algorithm for Kramers-Kronig analysis. The absolute reflectance spectrum of the alluvium and loess was determined using the relative reflectance measurements, the optical constants of distilled water and the Cauchy equation for reflectance. It is very desirable to make water quality measurements remotely. However before such measurements can be taken the characteristic manner in which aqueous solutions reflect electromagnetic radiation (in the optical properties) must be known. Thus the results obtained from this research are a part of a much larger goal to determine water quality remotely.Project # A-063-MO Agreement # 14-31-0001-382

Encounters With Ethical Problems During the First 5 Years of Practice in Occupational Therapy: A Survey

Background: Health care professionals face ethical problems in practice, but there is little research on types of ethical problems encountered or ethical problem resolution. This study explored ethical problems encountered by occupational therapists and occupational therapy assistants (OTAs) within the first 5 years of practice. Method: Investigators sent a survey in cooperation with NBCOT to a sample of 7,800 occupational therapists and OTAs in multiple practice settings who were NBCOT certified within the past five years. The survey covered questions regarding ethical problems encountered in practice, including productivity and related issues, clinical decision-making and professional reasoning, therapeutic relationships, and employer/employee and colleague relationships. Results: Occupational therapists and OTAs (n = 125) completed the survey. The most consistently encountered types of ethical problems included productivity and related issues and conflicts over clinical decision-making. Occupational therapists and OTAs working in adult and older adult settings reported more consistent encounters with ethical problems than practitioners in other settings. Occupational therapists and OTAs who have been NBCOT certified for longer experienced ethical problems more consistently. Conclusion: Implications included providing more support in specific ethics topics for practitioners within the first 5 years. Further research in which types of ethics education best prepare practitioners to manage ethical issues is warranted
