Human Papillomavirus (HPV) Vaccination Status Among University Freshmen in Hawaiāi
Purpose/Background: The HPV vaccine provides immunity against nine HPV strains that cause cancer and genital warts. It is recommended for 11 to 12 year olds, and catch-up immunization is recommended for females 13 to 26 years old and males 13 to 21 years old. College students represent an important population for HPV vaccination due to their increased risk for HPV infection. Despite the benefits of the HPV vaccine, its coverage rates are low in Hawaii. Hawaiāi is the home of two large universities on two islands that are representative of Hawaiāiās populations, including Native Hawaiians, Filipinos, and Pacific Islanders. The purpose of this study was to assess the current HPV and HPV vaccine knowledge, barriers and beliefs among incoming Freshmen university students at University of Hawaiāi at MÄnoa and University of Hawaiāi at Hilo.
Materials & Methods: In 2016, 200 University of Hawaiāi at MÄnoa (UHM) and University of Hawaiāi at Hilo (UHH) Freshmen students responded to a survey that assessed their knowledge and awareness of HPV, the HPV vaccine, their current vaccination status, and barriers and motivators to vaccination. Descriptive statistics were used to summarize each survey variable first for all students and then separately for each campus.
Results: Overall 76% of Freshmen from both campuses heard of the HPV vaccine and 54% reported hearing it from their health care provider. Only 28% UHM and 23% UHH Freshmen students have received partial (1-2 shots) or completed doses of the HPV vaccine. For those who received the vaccine, 45% reported that they were told by their parent and 43% were told by their doctor. For the 147 students who did not receive the vaccine, 28% reported that they are still not sure to get it and 20% need more information. Their main reasons for not receiving the HPV vaccine were: their doctor did not mention the vaccine to him/her (44%), he/she never knew about the vaccine (18%), and they don\u27t know enough about the vaccine (17%).
Discussion/Conclusion: Although the HPV vaccine has been available for 13 years, young adults remain unvaccinated. Freshmen students reported that they are informed about the vaccine, but were not vaccinated because of the lack of parental and/or healthcare provider recommendation. With no active education campaigns in Hawaii promoting the HPV vaccine at college campuses, a first step to increasing vaccination rates is to develop a health education campaign to inform students of the HPV vaccine and its availability at campus clinics and neighboring pharmacies
Relativistic theory of the double photoionization of helium-like atoms
A fully relativistic calculation of the double photoionization of helium-like
atoms is presented. The approach is based on the partial-wave representation of
the Dirac continuum states and accounts for the retardation in the
electron-electron interaction as well as the higher-order multipoles of the
absorbed photon. The electron-electron interaction is taken into account to the
leading order of perturbation theory. The relativistic effects are shown to
become prominent already for the medium-Z ions, changing the shape and the
asymptotic behaviour of the photon energy dependence of the ratio of the
double-to-single photoionization cross section

Contemporary Guarani Shamanisms: āTraditional Medicineā and Discourses of Native Identity in Brazil
The psychoactive substance known as ayahuasca has long been identified with Amazonian shamanism and traditional medicine. Over the last two decades its use has spread outside this region to urban populations in different parts of the world. This paper examines the adoption of the ritual use of the beverage by the Guarani Indians along the southern coast of Brazil. We argue that this process is related to the growing politics of identity of Brazilian indigenous peoples as well as to public policies that promote cultural diversity. In the case analyzed here, the adoption of ayahuasca is articulated with an ongoing cultural revitalization in activities related to shamanism, health and education and with the specific desires and actions of the leading family in one Guarani village
Non-locality of Foldy-Wouthuysen and related transformations for the Dirac equation
Non-localities of Foldy-Wouthuysen and related transformations, which are
used to separate positive and negative energy states in the Dirac equation, are
investigated. Second moments of functional kernels generated by the
transformations are calculated, the transformed functions and their variances
are computed. It is shown that all the transformed quantities are smeared in
the coordinate space by the amount comparable to the Compton wavelength

Virtual light-by-light scattering and the g factor of a bound electron
The contribution of the light-by-light diagram to the g factor of electron
and muon bound in Coulomb field is obtained. For electron in a ground state,
our results are in good agreement with the results of other authors obtained
numerically for large Z. For relatively small Z our results have essentially
higher accuracy as compared to the previous ones. For muonic atoms, the
contribution is obtained for the first time with the high accuracy in whole
region of Z.Comment: 10 pages, 3 figures, RevTe
Spin-orbit induced interference in polygon-structures
We investigate the spin-orbit induced spin-interference pattern of ballistic
electrons travelling along any regular polygon. It is found that the
spin-interference depends strongly on the Rashba and Dresselhaus spin-orbit
constants as well as on the sidelength and alignment of the polygon. We derive
the analytical formulae for the limiting cases of either zero Dresselhaus or
zero Rashba spin-orbit coupling, including the result obtained for a circle. We
calculate the nonzero Dresselhaus and Rashba case numerically for the square,
triangle, hexagon, and circle and discuss the observability of the
spin-interference which can potentially be used to measure the Rashba and
Dresselhaus coefficients.Comment: 17 pages, 4 figure
Retrieval of mass and sizes of particles in sandstorms using two MODIS IR bands: A case study of april 7 2001 sandstorm in China
A thermal infrared remote sensing retrieval method developed by Wen and Rose [1994], which retrieves particle sizes, optical depth, and total masses of silicate particles in the volcanic cloud, was applied to an April 07, 2001 sandstorm over northern China, using MODIS. Results indicate that the area of the dust cloud observed was 1.34 million km2, the mean particle radius of the dust was 1.44 Ī¼m, and the mean optical depth at 11 Ī¼m was 0.79. The mean burden of dust was approximately 4.8 tons/km2 and the main portion of the dust storm on April 07, 2001 contained 6.5 million tons of dust. The results are supported by both independent remote sensing data (TOMS) and in-situ data for a similar event in 1998. This paper demonstrates that Wen and Roseās retrieval method could be successfully applied to past and future sandstorm events using IR channels of AVHRR, GOES or MODIS
