Increasing HPV Vaccination Rates Using Social Marketing Strategies

The human papillomavirus (HPV) is the most common sexually-transmitted infection (STI). Approximately 20 million Americans between the ages of 15 and 49 years currently have HPV with \u3e 6.2 million new HPV infections estimated to occur each year. Yet, HPV vaccination rates remain relatively low. More than 40 strains of HPV are transmitted through genital contact during vaginal, anal, or oral sex and can infect males and females. In addition to causing genital warts, HPV is associated with cervical, vulvar, vaginal, anus, penile, and oropharyngeal cancers. In women, the most prominent type of cancer is cervical with \u3e 12,000 diagnoses each year and 4,000 expected to die. In Mississippi, a total of 1,829 HPV-associated cancers were diagnosed between 2004 and 2008, with an average of 33,369 cases in the United States (Centers for Disease Control and Prevention [CDC], 2012a). In 2000, the estimated cost of management of HPV for individuals between the age of 15 and 24 years totaled $2.9 billion. The aim of this study was to increase vaccination rates using social marketing strategies. The study was guided by an integrative approach using education sessions and pretest/posttest design to evaluate knowledge of HPV. Research data were obtained from 25 participants between the ages of 18 and 20 years. According to the CDC (2012c), males and females between the ages of 9 and 26 years should be offered the Gardasil® vaccine to achieve disease prevention. Research findings revealed increasing knowledge about HPV caused an increase in the number of students that received the vaccine after the intervention

Process for ultra smooth diamond coating on metals and uses thereof

The present invention provides a new process to deposit well adhered ultra smooth diamond films on metals by adding nitrogen gas to the methane/hydrogen plasma created by a microwave discharge. Such diamond coating process is useful in tribological/wear resistant applications in bio-implants, machine tools, and magnetic recording industry

Thermal Stability and Mechanical Properties of Sputtered Chromium-Molybdenum-Nitride (CrMoN) Coatings

Purpose: The purpose of paper is to determinate thermal stability and mechanical properties of sputtered chromium-molybdenum-nitride (CrMoN) coatings. Design/methodology/approach: We have deposited 1.8 m-thick ternary Cr0.5Mo0.5N1.0 films on a CoCrMo alloy using a RF dual magnetron sputtering system, with Cr and Mo targets and N2 as the reactive gas. These films were subjected to various thermal treatments in Ar, air, and microwave plasma. The hardness, Young’s modulus, surface roughness, microstructure, and composition of films were studied by nanoindentation, AFM, x-ray diffraction, and x-ray photoelectron spectroscopy. Findings: The as-prepared CrMoN films consist of an amorphous Cr-rich nitride matrix with Mo-rich nitride crystalline grains, about 15 nm in size. These films are thermally stable up to 600ºC in air. Thermal annealing in the air at 800ºC resulted in an increase in surface roughness and hardness, due to film oxidation, with Cr2O3 as the main crystalline phase. Plasma treatment in a H2/N2 gas mixture, at 800ºC, did not lead to grain growth. Instead, the existing grains were reduced to about 10 nm and a new nanocrystalline phase has been formed. This leads to a decrease in the surface roughness, and an increase in the film hardness. In addition, we have further modified the film properties through a combined thermal treatment process. Thermal annealing in the air at 800ºC, followed by microwave plasma treatment at 800ºC resulted in a film with decreased surface roughness, and improved mechanical properties. Reversing the order of the thermal treatments resulted in a further decrease in surface roughness, but it shows a reduction in the mechanical properties. Research limitations/implications: The present investigation was carried out with only one composition, Cr0.5Mo0.5N1.0, of ternary thin-film system. Originality/value: The combination of thermal and plasma treatments can be used to control the microstructure, surface topography, and mechanical properties of ternary CrMoN films. Such post-deposition treatments can further improve the materials properties for desired application, and to produce new nanocomposite materials with technologically important combination of properties.National Science Foundation under grants DMR-0806521 and OISE-085494

Characterizing web pornography consumption from passive measurements

Web pornography represents a large fraction of the Internet traffic, with thousands of websites and millions of users. Studying web pornography consumption allows understanding human behaviors and it is crucial for medical and psychological research. However, given the lack of public data, these works typically build on surveys, limited by different factors, e.g. unreliable answers that volunteers may (involuntarily) provide. In this work, we collect anonymized accesses to pornography websites using HTTP-level passive traces. Our dataset includes about $15\,000$ broadband subscribers over a period of 3 years. We use it to provide quantitative information about the interactions of users with pornographic websites, focusing on time and frequency of use, habits, and trends. We distribute our anonymized dataset to the community to ease reproducibility and allow further studies.Comment: Passive and Active Measurements Conference 2019 (PAM 2019). 14 pages, 7 figure

In this paper, we describe an information access system with a voice-only interface. We outline a design process for generating guidelines for voice-only interaction in the absence of adequate speech recognition technology. Our usability studies make use of a "Wizard of Oz" scheme to replace the missing core technology

Magnetic susceptibility measurements at high pressure using designer diamond anvils

High pressure magnetic susceptibility experiments can yield valuable insights into the changes in magnetic behavior and electron correlation properties which can accompany extreme compressions of matter. However, magnetic susceptibility experiments with ultrahigh pressure diamond anvil cells are extremely challenging due to the very small size of the high-pressure sample ͑Ϸ75 m diameter͒ and the difficulty of obtaining good coupling between the sample and the sensing coil. As a result, measurement sensitivity and poor signal-to-background ratios tend to be serious concerns which limit the applicability of these experiments. We present here a new approach to high-pressure ac magnetic susceptibility experiments that involve specially fabricated diamond anvils with diamond encapsulated sensing microcoils which are located just 10-20 m from the high-pressure sample. We also present some test results taken with a gadolinium sample in order to demonstrate the viability of this high-pressure ac susceptibility technique
