Modernization and unification: Strategic goals for NASA STI program

NASA Technical Reports Server (NTRS)

Blados, W.; Cotter, Gladys A.

1993-01-01

Information is increasingly becoming a strategic resource in all societies and economies. The NASA Scientific and Technical Information (STI) Program has initiated a modernization program to address the strategic importance and changing characteristics of information. This modernization effort applies new technology to current processes to provide near-term benefits to the user. At the same time, we are developing a long-term modernization strategy designed to transition the program to a multimedia, global 'library without walls.' Notwithstanding this modernization program, it is recognized that no one information center can hope to collect all the relevant data. We see information and information systems changing and becoming more international in scope. We are finding that many nations are expending resources on national systems which duplicate each other. At the same time that this duplication exists, many useful sources of aerospace information are not being collected because of resource limitations. If nations cooperate to develop an international aerospace information system, resources can be used efficiently to cover expanded sources of information. We must consider forming a coalition to collect and provide access to disparate, multidisciplinary sources of information, and to develop standardized tools for documenting and manipulating this data and information. In view of recent technological developments in information science and technology, as well as the reality of scarce resources in all nations, it is time to explore the mutually beneficial possibilities offered by cooperation and international resource sharing. International resources need to be mobilized in a coordinated manner to move us towards this goal. This paper reviews the NASA modernization program and raises for consideration new possibilities for unification of the various aerospace database efforts toward a cooperative international aerospace database initiative that can optimize the cost

[NASA/DOD Aerospace Knowledge Diffusion Research Project. Paper 18:] Scientific and Technical Information (STI) policy and the competitive position of the US aerospace industry

NASA Technical Reports Server (NTRS)

Hernon, Peter; Pinelli, Thomas E.

1992-01-01

With its contribution to trade, its coupling with national security, and its symbolism of U.S. technological strength, the U.S. aerospace industry holds a unique position in the Nation's industrial structure. Federal science and technology policy and Federal scientific and technical information (STI) policy loom important as strategic contributions to the U.S. aerospace industry's leading competitive position. However, three fundamental policy problems exist. First, the United States lacks a coherent STI policy and a unified approach to the development of such a policy. Second, policymakers fail to understand the relationship of STI to science and technology policy. Third, STI is treated as a part of general information policy, without any recognition of its uniqueness. This paper provides an overview of the Federal information policy structure as it relates to STI and frames the policy issues that require resolution.

NASA Access Mechanism - Graphical user interface information retrieval system

NASA Technical Reports Server (NTRS)

Hunter, Judy F.; Generous, Curtis; Duncan, Denise

1993-01-01

Access to online information sources of aerospace, scientific, and engineering data, a mission focus for NASA's Scientific and Technical Information Program, has always been limited by factors such as telecommunications, query language syntax, lack of standardization in the information, and the lack of adequate tools to assist in searching. Today, the NASA STI Program's NASA Access Mechanism (NAM) prototype offers a solution to these problems by providing the user with a set of tools that provide a graphical interface to remote, heterogeneous, and distributed information in a manner adaptable to both casual and expert users. Additionally, the NAM provides access to many Internet-based services such as Electronic Mail, the Wide Area Information Servers system, Peer Locating tools, and electronic bulletin boards.

NASA's experience in the international exchange of scientific and technical information in the aerospace field

NASA Technical Reports Server (NTRS)

Thibideau, Philip A.

1989-01-01

The early NASA international scientific and technical information (STI) exchange arrangements were usually detailed in correspondence with the librarians of the institutions involved. While this type of exchange, which involved only hardcopy (paper) products, grew to include some 220 organization in 43 countries, NASA's main focus shifted substantially to the STI relationship with the European Space Agency (ESA) which began in 1964. The NASA/ESA Tripartite Exchange Program, which now has more than 500 participants, provides more than 4,000 highly-relevant technical reports, fully processed, for the NASA produced 'Aerospace Database'. In turn, NASA provides an updated copy of this Database, known in Europe as the 'NASA File', for access, through ESA's Information Retrieval Service, by participating European organizations. Our experience in the evolving cooperation with ESA has established the 'model' for our more recent exchange agreements with Israel, Australia, Canada, and one under negotiation with Japan. The results of these agreements are made available to participating European organizations through the NASA File.

NASA Publications Guide for Authors

NASA Technical Reports Server (NTRS)

1999-01-01

Publication of scientific and technical information (STI) is one of the responsibilities of NASA as a Government Agency. The National Aeronautics and Space Act of 1958 established a requirement for NASA to provide "the widest practicable and appropriate dissemination of information concerning its activities and the results thereof." Persons engaged in NASA-funded or NASA-sponsored research and development and related efforts are therefore required to publish the results of their work in the NASA STI series or through other externally accessible channels. An Agency-wide committee of publications professionals prepared the standards and conventions presented in this guide for authors. Section 2 of this guide presents descriptions of each type of report in the NASA STI Report Series and briefly discusses the applicable production methods and appropriate dissemination of these reports. Section 3 discusses professional and ethical concerns. Section 4 provides recommended standards for document format, makeup, and organization. Section 5 presents miscellaneous preparation concerns.

National security and national competitiveness: Open source solutions; NASA requirements and capabilities

NASA Technical Reports Server (NTRS)

Cotter, Gladys A.

1993-01-01

Foreign competitors are challenging the world leadership of the U.S. aerospace industry, and increasingly tight budgets everywhere make international cooperation in aerospace science necessary. The NASA STI Program has as part of its mission to support NASA R&D, and to that end has developed a knowledge base of aerospace-related information known as the NASA Aerospace Database. The NASA STI Program is already involved in international cooperation with NATO/AGARD/TIP, CENDI, ICSU/ICSTI, and the U.S. Japan Committee on STI. With the new more open political climate, the perceived dearth of foreign information in the NASA Aerospace Database, and the development of the ESA database and DELURA, the German databases, the NASA STI Program is responding by sponsoring workshops on foreign acquisitions and by increasing its cooperation with international partners and with other U.S. agencies. The STI Program looks to the future of improved database access through networking and a GUI; new media; optical disk, video, and full text; and a Technology Focus Group that will keep the NASA STI Program current with technology.

Pinelli, Thomas E.; Glassman, Myron

1989-01-01

A pilot study was conducted to evaluate selected NASA scientific and technical information (STI) products. The study, which utilized survey research in the form of a self-administered mail questionnaire, had a two-fold purpose -- to gather baseline data regarding the use and perceived usefulness of selected NASA STI products and to develop/validate questions that could be used in a future study concerned with the role of the U.S. government technical report in aeronautics. The sample frame consisted of 25,000 members of the American Institute of Aeronautics and Astronautics in the U.S. with academic, government or industrial affiliation. Simple random sampling was used to select 2000 individuals to participate in the study. Three hundred fifty-three usable questionnaires (17 percent response rate) were received by the established cutoff date. The findings indicate that: (1) NASA STI is used and is generally perceived as being important; (2) the use rate for NASA-authored conference/meeting papers, journal articles, and technical reports is fairly uniform; (3) a considerable number of respondents are unfamiliar with STAR (Scientific and Technical Aerospace Reports), IAA (International Aerospace Abstracts), SCAN (Selected Current Aerospace Notices), and the RECON on-line retrieval system; (4) a considerable number of respondents who are familiar with these media do not use them; and (5) the perceived quality of NASA-authored journal articles and technical reports is very good.

NASA thesaurus. Volume 3: Definitions

NASA Technical Reports Server (NTRS)

1988-01-01

Publication of NASA Thesaurus definitions began with Supplement 1 to the 1985 NASA Thesaurus. The definitions given here represent the complete file of over 3,200 definitions, complimented by nearly 1,000 use references. Definitions of more common or general scientific terms are given a NASA slant if one exists. Certain terms are not defined as a matter of policy: common names, chemical elements, specific models of computers, and nontechnical terms. The NASA Thesaurus predates by a number of years the systematic effort to define terms, therefore not all Thesaurus terms have been defined. Nevertheless, definitions of older terms are continually being added. The following data are provided for each entry: term in uppercase/lowercase form, definition, source, and year the term (not the definition) was added to the NASA Thesaurus. The NASA History Office is the authority for capitalization in satellite and spacecraft names. Definitions with no source given were constructed by lexicographers at the NASA Scientific and Technical Information (STI) Facility who rely on the following sources for their information: experts in the field, literature searches from the NASA STI database, and specialized references.

Quo vadimus: Coming to grips with the information world

NASA Technical Reports Server (NTRS)

Blados, Walter R.

1991-01-01

The new information-oriented culture in which we find ourselves has created new relationships, new stimulating and expanding opportunities, new methods of doing our work, and new environments in which we carry out our work. An integral part of the NASA aerospace research and development (R and D) process is the scientific and technical information (STI) associated with it; it is both a raw material (input) and a product (output) of this process. Within this process, the NASA STI Program is tasked to provide information management and services, to ensure that accurate and timely STI is generated and entered into an appropriate information service and made available in a usable form to those who have a need for it; in essence, a means to exploit both internal (NASA corporate) and pertinent external (other governmental/industrial/foreign) information to meet the requirements of the R and D community. To understand the STI Program management issues, it is critical to understand the role of the STI Program in the context of the R and D process. STI management must become part of the accepted culture of the R and D community, but it cannot become so unless adopted and accepted by it. A start should be made now to integrate the NASA STI Program into the R and D infrastructure, including funding and operational control. Within this infrastructure, we must obtain management commitment, review and produce policy reflecting the organizational status, allocate responsibilities, and set to work on implementing the true requirements of the R and D community.

The project is a cooperative US effort between NASA, DoD, and Indiana University. This research was endorsed by the AGARD Technical Information Panel and the American Institute of Aeronautics and Astronautics (AIAA) Technical Information Committee. The four-phase inquiry focuses on scientific and technical information (STI) as knowledge, the channels through which this knowledge is communicated, and the members of the social system associated with and involved in diffusing this knowledge throughout the aerospace community. The project is based on two premises: (1) although STI is essential to innovation, STI by itself does not ensure innovation; and (2) utilizing existing STI or creating new STI, does often facilitate technological innovation. The topics covered include the following: information-seeking habits, knowledge transfer, academic sector, non-US organizations, present status, comparative study, and timetable.

How to use the WWW to distribute STI

NASA Technical Reports Server (NTRS)

Roper, Donna G.

1994-01-01

This presentation explains how to use the World Wide Web (WWW) to distribute scientific and technical information as hypermedia. WWW clients and servers use the HyperText Transfer Protocol (HTTP) to transfer documents containing links to other text, graphics, video, and sound. The standard language for these documents is the HyperText MarkUp Language (HTML). These are simply text files with formatting codes that contain layout information and hyperlinks. HTML documents can be created with any text editor or with one of the publicly available HTML editors or convertors. HTML can also include links to available image formats. This presentation is available online. The URL is http://sti.larc.nasa. (followed by) gov/demos/workshop/introtext.html.

2007-01-01

Machine Aided Indexing (MAI) is a Web-based application program for aiding the indexing of literature in the NASA Scientific and Technical Information (STI) Database. MAI was designed to be a convenient, fully interactive tool for determining the subject matter of documents and identifying keywords. The heart of MAI is a natural-language processor that accepts, as input, any user-supplied text, including abstracts, full documents, and Web pages. Within seconds, the text is analyzed and a ranked list of terms is generated. The 17,800 terms of the NASA Thesaurus serve as the foundation of the knowledge base used by MAI. The NASA Thesaurus defines a standard vocabulary, the use of which enables MAI to assist in ensuring that STI documents are uniformly and consistently accessible. Of particular interest to traditional users of the NASA Thesaurus, MAI incorporates a fully searchable thesaurus display module that affords word-search and hierarchy- navigation capabilities that make it much easier and less time-consuming to look up terms and browse, relative to lookup and browsing in older print and Portable Document Format (PDF) digital versions of the Thesaurus. In addition, because MAI is centrally hosted, the Thesaurus data are always current.

NASA/DOD Aerospace Knowledge Diffusion Research Project. Paper 11: The Voice of the User: How US Aerospace Engineers and Scientists View DoD Technical Reports

NASA Technical Reports Server (NTRS)

Pinelli, Thomas E.; Kennedy, John M.

1991-01-01

The project examines how the results of NASA/DOD research diffuse into the aerospace R&D process, and empirically analyzes the implications of the aerospace knowledge diffusion process. Specific issues considered are the roles played by government technical reports, the recognition of the value of scientific and technical information (STI), and the optimization of the STI aerospace transfer system. Information-seeking habits are assessed for the U.S. aerospace community, the general community, the academic sector, and the international community. U.S. aerospace engineers and scientists use 65 percent of working time to communicate STI, and prefer 'internal' STI over 'external' STI. The isolation from 'external' information is found to be detrimental to U.S. aerospace R&D in general.

In fiscal year 1994, the United States government spent about $68 billion for science and technology. Although there is general agreement among policy makers that the results of this expenditure can be used to enhance technological innovation and improve economic competitiveness, there is no coherent scientific and technical information (STI) policy. The absence of a cohesive policy and STI policy framework means that the transfer and utilization of STI goes uncoordinated. This chapter examines the U.S. government's role in funding science and technology, reviews Federal STI activities and involvement in the transfer and use of STI resulting from federally-funded science and technology, presents issues surrounding the use of federally-funded STI, and offers recommendations for improving the transfer and use of STI.

Sexual behavior during travel has increasingly become a focus of travel medicine research. The perceived freedom when away from home can lead to increased casual sexual activities, often unprotected. Local sexual partners, particularly those who are in close contact with tourists due to their occupation, need to be considered more in research. The purpose of this study was to explore the sexual behavior, knowledge of STI prevention, and prevalence of serum markers of selected STIs in tour guides in Cuzco/Peru. In this cross-sectional study, 161 tour guides completed a questionnaire consisting of information on demographics, sexual behavior, and knowledge about STI prevention. Blood samples of the participants were tested for antibodies against HSV2, Chlamydia trachomatis, and Treponema pallidum using commercial enzyme-linked immunosorbent assay kits. The majority of guides (65%) were sexually active during the year prior to the study and 10% had foreign partners. Consistent condom use was reported by 38.1%, but almost 42% did not use condoms. In total, 27.6% reported symptoms compatible with STI. Three quarters of the participants had previously received information on STI prevention, predominantly from health professionals. In total, 22% considered themselves at high risk for STI. Antibodies against C trachomatis were prevalent in 15%, while 88.2% were against HSV2. None had antibodies against T pallidum. There is an inconsistency in reported sexual behavior and reported knowledge about STI prevention. Because of the tour guides' bridging position between potential STI carriers in tourists and the local population, the reported nonuse of condoms is of concern. The prevalence of serum markers supports this concern, which is aggravated by the potential of noncurable infections. Current sexual health education strategies seem unsatisfactory, and major modifications are highly recommended.

1991-01-01

Phase 3 of a 4 part study was undertaken to study the use of scientific and technical information (STI) in the academic aerospace community. Phase 3 of this project used three questionnaires that were sent to three groups (i.e., faculty, librarians, and students) in the academic aerospace community. Specific attention was paid to the types of STI used and the methods in which academic users acquire STI. The responses of the academic libraries are focussed on herein. Demographic information on academic aerospace libraries is provided. Data regarding NASA interaction with academic aerospace libraries is also included, as is the survey instrument.

Actions Needed to Ensure Scientific and Technical Information is Adequately Reviewed at Goddard Space Flight Center, Johnson Space Center, Langley Research Center, and Marshall Space Flight Center

NASA Technical Reports Server (NTRS)

2008-01-01

This audit was initiated in response to a hotline complaint regarding the review, approval, and release of scientific and technical information (STI) at Johnson Space Center. The complainant alleged that Johnson personnel conducting export control reviews of STI were not fully qualified to conduct those reviews and that the reviews often did not occur until after the STI had been publicly released. NASA guidance requires that STI, defined as the results of basic and applied scientific, technical, and related engineering research and development, undergo certain reviews prior to being released outside of NASA or to audiences that include foreign nationals. The process includes technical, national security, export control, copyright, and trade secret (e.g., proprietary data) reviews. The review process was designed to preclude the inappropriate dissemination of sensitive information while ensuring that NASA complies with a requirement of the National Aeronautics and Space Act of 1958 (the Space Act)1 to provide for the widest practicable and appropriate dissemination of information resulting from NASA research activities. We focused our audit on evaluating the STI review process: specifically, determining whether the roles and responsibilities for the review, approval, and release of STI were adequately defined and documented in NASA and Center-level guidance and whether that guidance was effectively implemented at Goddard Space Flight Center, Johnson Space Center, Langley Research Center, and Marshall Space Flight Center. Johnson was included in the review because it was the source of the initial complaint, and Goddard, Langley, and Marshall were included because those Centers consistently produce significant amounts of STI.

The recognition and modification sites for the bacterial type I restriction systems KpnAI, StySEAI, StySENI and StySGI

PubMed Central

Kasarjian, Julie K. A.; Hidaka, Masumi; Horiuchi, Takashi; Iida, Masatake; Ryu, Junichi

2004-01-01

Using an in vivo plasmid transformation method, we have determined the DNA sequences recognized by the KpnAI, StySEAI, StySENI and StySGI R-M systems from Klebsiella oxytoca strain M5a1, Salmonella eastbourne, Salmonella enteritidis and Salmonella gelsenkirchen, respectively. These type I restriction-modification systems were originally identified using traditional phage assay, and described here is the plasmid transformation test and computer program used to determine their DNA recognition sequences. For this test, we constructed two sets of plasmids, pL and pE, that contain phage lambda and Escherichia coli K-12 chromosomal DNA fragments, respectively. Further, using the methylation sensitivities of various known type II restriction enzymes, we identified the target adenines for methylation (listed in bold italics below as A or T in case of the complementary strand). The recognition sequence and methylation sites are GAA(6N)TGCC (KpnAI), ACA(6N)TYCA (StySEAI), CGA(6N)TACC (StySENI) and TAAC(7N)RTCG (StySGI). These DNA recognition sequences all have a typical type I bipartite pattern and represent three novel specificities and one isoschizomer (StySENI). For confirmation, oligonucleotides containing each of the predicted sequences were synthesized, cloned into plasmid pMECA and transformed into each strain, resulting in a large reduction in efficiency of transformation (EOT).

This paper discusses the technical aspects of and the project background for the NASA Image exchange (NIX). NIX, which provides a single entry point to search selected image databases at the NASA Centers, is a meta-search engine (i.e., a search engine that communicates with other search engines). It uses these distributed digital image databases to access photographs, animations, and their associated descriptive information (meta-data). NIX is available for use at the following URL: http://nix.nasa.gov./NIX, which was sponsored by NASAs Scientific and Technical Information (STI) Program, currently serves images from seven NASA Centers. Plans are under way to link image databases from three additional NASA Centers. images and their associated meta-data, which are accessible by NIX, reside at the originating Centers, and NIX utilizes a virtual central site that communicates with each of these sites. Incorporated into the virtual central site are several protocols to support searches from a diverse collection of database engines. The searches are performed in parallel to ensure optimization of response times. To augment the search capability, browse functionality with pre-defined categories has been built into NIX, thereby ensuring dissemination of 'best-of-breed' imagery. As a final recourse, NIX offers access to a help desk via an on-line form to help locate images and information either within the scope of NIX or from available external sources.

Unification - An international aerospace information issue

NASA Technical Reports Server (NTRS)

Cotter, Gladys A.; Lahr, Thomas F.

1992-01-01

Scientific and Technical Information (STI) represents the results of large investments in research and development (R&D) and the expertise of a nation and is a valuable resource. For more than four decades, NASA and its predecessor organizations have developed and managed the preeminent aerospace information system. NASA obtains foreign materials through its international exchange relationships, continually increasing the comprehensiveness of the NASA Aerospace Database (NAD). The NAD is de facto the international aerospace database. This paper reviews current NASA goals and activities with a view toward maintaining compatibility among international aerospace information systems, eliminating duplication of effort, and sharing resources through international cooperation wherever possible.

1994-01-01

The U.S. aerospace industry has a long history of federal support for research related to its needs. Since the establishment of the National Advisory Committee for Aeronautics (NACA) in 1915, the federal government has provided continuous research support related to flight and aircraft design. This research has contributed to the international preeminence of the U.S. aerospace industry. In this paper, we present a sociological analysis of aerospace engineers and scientists and how their attitudes and behaviors impact the flow of scientific and technical information (STI). We use a constructivist framework to explain the spotty dissemination of federally funded aerospace research. Our research is aimed towards providing federal policymakers with a clearer understanding of how and when federally funded aerospace research is used. This understanding will help policymakers design improved information transfer systems that will aid the competitiveness of the U.S. aerospace industry.

Sexual risk behavior and STI health literacy among ethnic minority adolescent women.

PubMed

Dimmitt Champion, Jane; Harlin, Badia; Collins, Jennifer L

2013-11-01

Although information is available for prevention of sexually transmitted infection (STI/HIV), adolescents continue to engage in high risk sexual behavior particularly ethnic minority adolescent women with histories of STI or abuse. A description therefore of STI/HIV knowledge and sexual risk behavior among these women is indicated for modification of prevention efforts for sexual health promotion. African-American (n=94) and Mexican-American (n=465) adolescent women 14-18 years of age were included in the study. Assessments of sexual risk behavior and STI/HIV knowledge among these adolescent women described Mexican-American women as at higher risk of STI, pregnancy, substance use and abuse with lower levels of STI/HIV knowledge, previous HIV testing and perceptions of risk than African-American women. A focus on Mexican-American adolescent women with histories of STI and abuse is indicated for translation of community-based health promotion interventions for amelioration of potential adverse sexual health outcomes among ethnic minority adolescent women. © 2013.

1993-01-01

Today we are in the midst of information and 'total quality' revolutions. At the NASA STI Program's Center for AeroSpace Information (CASI), we are focused on using continuous improvements techniques to enrich today's services and products and to ensure that tomorrow's technology supports the TQM-based improvement of future STI program products and services. The Continuous Improvements Program at CASI is the foundation for Total Quality Management in products and services. The focus is customer-driven; its goal, to identify processes and procedures that can be improved and new technologies that can be integrated with the processes to gain efficiencies, provide effectiveness, and promote customer satisfaction. This Program seeks to establish quality through an iterative defect prevention approach that is based on the incorporation of standards and measurements into the processing cycle. Four projects are described that utilize cross-functional, problem-solving teams for identifying requirements and defining tasks and task standards, management participation, attention to critical processes, and measurable long-term goals. The implementation of these projects provides the customer with measurably improved access to information that is provided through several channels: the NASA STI Database, document requests for microfiche and hardcopy, and the Centralized Help Desk.

NASA/DOD Aerospace Knowledge Diffusion Research Project. Paper 45: A comparison of the information-seeking behaviors of three groups of US aerospace engineers

Kennedy, John M.; Pinelli, Thomas E.; Barclay, Rebecca O.

1995-01-01

To understand the transfer of scientific and technical information (STI) in aerospace, it is necessary to understand the characteristics and behaviors of those who create and use STI. In this paper, we analyze the similarities and differences in the scientific and technical information-seeking behaviors of three groups of US aerospace engineers and scientists. We describe some of their demographic characteristics and their duties and responsibilities as a method of understanding their STI use patterns. There is considerable diversity among aerospace engineers in their use of STI. In general, engineers engaged in research use more STI than those who are in design/development and manufacturing/production. Research engineers also use different standards to determine the STI sources and products that they will use.

2016-01-15

Ensuring rapid access to high quality sexual health services is a key public health objective, both in the United Kingdom and internationally. Internet-based testing services for sexually transmitted infections (STIs) are considered to be a promising way to achieve this goal. This study will evaluate a nascent online STI testing and results service in South East London, delivered alongside standard face-to-face STI testing services. The aim of this study is to establish whether an online testing and results services can (1) increase diagnoses of STIs and (2) increase uptake of STI testing, when delivered alongside standard face-to-face STI testing services. This is a single-blind randomized controlled trial. We will recruit 3000 participants who meet the following eligibility criteria: 16-30 years of age, resident in the London boroughs of Lambeth and Southwark, having at least one sexual partner in the last 12 months, having access to the Internet and willing to take an STI test. People unable to provide informed consent and unable to read and understand English (the websites will be in English) will be excluded. Baseline data will be collected at enrolment. This includes participant contact details, demographic data (date of birth, gender, ethnicity, and sexual orientation), and sexual health behaviors (last STI test, service used at last STI test and number of sexual partners in the last 12 months). Once enrolled, participants will be randomly allocated either (1) to an online STI testing and results service (Sexual Health 24) offering postal self-administered STI kits for chlamydia, gonorrhoea, syphilis, and HIV; results via text message (short message service, SMS), except positive results for HIV, which will be delivered by phone; and direct referrals to local clinics for treatment or (2) to a conventional sexual health information website with signposting to local clinic-based sexual health services. Participants will be free to use any other interventions

Correlates of STI testing among vocational school students in the Netherlands

PubMed Central

2010-01-01

Background Adolescents are at risk for acquiring sexually transmitted infections (STIs). However, test rates among adolescents in the Netherlands are low and effective interventions that encourage STI testing are scarce. Adolescents who attend vocational schools are particularly at risk for STI. The purpose of this study is to inform the development of motivational health promotion messages by identifying the psychosocial correlates of STI testing intention among adolescents with sexual experience attending vocational schools. Methods This study was conducted among 501 students attending vocational schools aged 16 to 25 years (mean 18.3 years ± 2.1). Data were collected via a web-based survey exploring relationships, sexual behavior and STI testing behavior. Items measuring the psychosocial correlates of testing were derived from Fishbein's Integrative Model. Data were subjected to multiple regression analyses. Results Students reported substantial sexual risk behavior and low intention to participate in STI testing. The model explained 39% of intention to engage in STI testing. The most important predictor was attitude. Perceived norms, perceived susceptibility and test site characteristics were also significant predictors. Conclusions The present study provides important and relevant empirical input for the development of health promotion interventions aimed at motivating adolescents at vocational schools in the Netherlands to participate in STI testing. Health promotion interventions developed for this group should aim to change attitudes, address social norms and increase personal risk perception for STI while also promoting the accessibility of testing facilities.

Many young men who have sex with men (YMSM) are reluctant to seek health services and trust local physicians. Online information seeking may encourage YMSM to identify and see trustworthy physicians, obtain sexual health services, and obtain testing for sexually transmitted infections (STIs). This study examined online STI information seeking behaviors among Chinese YMSM and its association with offline physician visits. We conducted a nationwide online survey among YMSM through WeChat, the largest social media platform in China. We collected information on individual demographics, sexual behaviors, online STI information seeking, offline STI testing, and STI physician visits. We examined the most commonly used platforms (search engines, governmental websites, counseling websites, generic social media, gay mobile apps, and mobile medical apps) and their trustworthiness. We assessed interest and willingness to use an MSM-friendly physician finder function embedded within a gay mobile app. Logistic regression models were used to examine the correlation between online STI information searching and offline physician visits. A total of 503 men completed the survey. Most men (425/503, 84.5%) searched for STI information online. The most commonly used platform to obtain STI information were search engines (402/425, 94.5%), followed by gay mobile apps (201/425, 47.3%). Men reported high trustworthiness of information received from gay mobile apps. Men also reported high interest (465/503, 92.4%) and willingness (463/503, 92.0%) to use a MSM-friendly physician finder function within such apps. Both using general social media (aOR =1.14, 95%CI: 1.04-1.26) and mobile medical apps (aOR =1.16, 95%CI: 1.01-1.34) for online information seeking were associated with visiting a physician. Online STI information seeking is common and correlated with visiting a physician among YMSM. Cultivating partnerships with the emerging mobile medical apps may be useful for disseminating STI

Inuit women's stories of strength: informing Inuit community-based HIV and STI prevention and sexual health promotion programming.

There is a dearth of literature to guide the development of community-based HIV and sexually transmitted infection (STI) prevention and sexual health promotion programs within Inuit communities. The aim of this study was to create a dialogue with Inuit women to address the lack of information available to inform programming to improve the sexual health of Inuit women, their families, and their communities in the Canadian Arctic. This study used Indigenous methodologies and methods by drawing from Inuit Qaujimajatuqangit and postcolonial research theory in a framework of Two-Eyed Seeing, and using storytelling sessions to gather data. Community-based participatory research principles informed the design of the study, ensuring participants were involved in all stages of the project. Nine storytelling sessions took place with 21 Inuit women aged 18-61 years. Storytelling sessions were audio recorded and transcribed verbatim, and Atlas.ti aided in the organization of the data for collaborative thematic analysis within three participatory analysis sessions with 13 of the participating women. From the storytelling and analysis sessions, five major themes emerged: (a) the way it used to be, (b) change, (c) family, (d) intimate relationships and (e) holistic strategies. Participating women emphasized that HIV and STI prevention and sexual health promotion programming needs to take a holistic, community-wide, family-focused and youth-centred approach within their communities. Participants identified several important determinants of sexual health and shared ideas for innovative approaches they believe will work as prevention efforts within their communities. This article specifically focuses on key characteristics of programming aimed at STI and HIV prevention and sexual health promotion that were identified throughout participants' stories. This study has provided a narrative to complement the epidemiological data that highlight the urgent need for prevention programming.

The dynamic nature of the IRM environment requires that the controlling management practices and procedures for an Agency at the leading edge of technology, such as NASA, must be periodically updated to reflect the changes in this environment. This revision has been undertaken to accommodate changes in the technology and the impact of new laws and regulations dealing with IRM. The contents of this document will be subject to a complete review annually to determine its continued applicability to the acquisition, management, and use of FIP resources by NASA. Updates to this document will be accomplished by page changes. This revision cancels NHB 2410.1D, dated April 1985.

The incidence of sexually transmitted infections (STIs) and human immunodeficiency virus (HIV) is high among young Chilean women, and there are no STI or HIV prevention interventions available to them that incorporate technology. The purpose of this study was to investigate the preliminary efficacy of an Internet-based STI and HIV prevention intervention (I-STIPI) for Chilean young women on measures of STI- and HIV-related information, motivation, behavioral skills, and preventive behaviors. This is a pretest-posttest study. Forty young Chilean women between 18 and 24 years of age participated in an investigation of the I-STIPI's preliminary efficacy on STI and HIV prevention-related outcomes between baseline and a postintervention assessment. The intervention consisted of four online modules. Data collection was conducted in Santiago, Chile. Paired-samples t test analysis was used to determine whether there were significant differences in each of the outcome variables. After receiving I-STIPI, women reported a significant increase in levels of STI- and HIV-related knowledge, attitudes toward the use of condoms and perceived self-efficacy, and a reduction of risky sexual behaviors with uncommitted partners. The I-STIPI showed promise as an Internet-based intervention that can reduce barriers to accessing preventive interventions and increase STI and HIV preventive behaviors in young Chilean women. The study provided important information about the ability of an Internet-based intervention to reduce young women's risk factors and to provide positive preliminary efficacy on STI- and HIV-related outcomes. Internet-based interventions can eliminate many barriers to receiving prevention interventions and may prove to be cost effective. © 2014 Sigma Theta Tau International.

Involvement of STI1 protein in the differentiation process of Trypanosoma cruzi.

PubMed

Schmidt, Juliana C; Manhães, Lauro; Fragoso, Stenio P; Pavoni, Daniela P; Krieger, Marco A

2018-04-01

The protozoan Trypanosoma cruzi is a parasite exposed to several environmental stressors inside its invertebrate and vertebrate hosts. Although stress conditions are involved in its differentiation processes, little information is available about the stress response proteins engaged in these activities. This work reports the first known association of the stress-inducible protein 1 (STI1) with the cellular differentiation process in a unicellular eukaryote. Albeit STI1 expression is constitutive in epimastigotes and metacyclic trypomastigotes, higher protein levels were observed in late growth phase epimastigotes subjected to nutritional stress. Analysis by indirect immunofluorescence revealed that T. cruzi STI1 (TcSTI1) is located throughout the cell cytoplasm, with some cytoplasmic granules appearing in greater numbers in late growing epimastigotes and late growing epimastigotes subjected to nutritional stress. We observed that part of the fluorescence signal from both TcSTI1 and TcHSP70 colocalized around the nucleus. Gene silencing of sti1 in Trypanosoma brucei did not affect cell growth. Similarly, the growth of T. cruzi mutant parasites with a single allele sti1 gene knockout was not affected. However, the differentiation of epimastigotes in metacyclic trypomastigotes (metacyclogenesis) was compromised. Lower production rates and numbers of metacyclic trypomastigotes were obtained from the mutant parasites compared with the wild-type parasites. These data indicate that reduced levels of TcSTI1 decrease the rate of in vitro metacyclogenesis, suggesting that this protein may participate in the differentiation process of T. cruzi.

The Millimeter Sky Transparency Imager (MiSTI) is a small millimeter-wave scanning telescope with a 25-cm diameter dish operating at 183 GHz. MiSTI is installed at Atacama, Chile, and it measures emission from atmospheric water vapor and its fluctuations to estimate atmospheric absorption in the millimeter to submillimeter range. MiSTI observes the water vapor distribution at a spatial resolution of 0.°5, and it is sensitive enough to detect an excess path length of lesssim0.05 mm for an integration time of 1 s. By comparing the MiSTI measurements with those by a 220 GHz tipper, we validated that the 183 GHz measurements of MiSTI are correct, down to the level of any residual systematic errors in the 220 GHz measurements. Since 2008, MiSTI has provided real-time (every 1 hr) monitoring of the all-sky opacity distribution and atmospheric transmission curves in the (sub)millimeter through the internet, allowing us to know the (sub)millimeter sky conditions at Atacama.

Sexually transmitted infection (STI) testing among young oil and gas workers: the need for innovative, place-based approaches to STI control.

Northeastern British Columbia is undergoing rapid in-migration of young, primarily male workers in response to the "boom" in the oil/gas industries. Accompanying the boom is a rise in Chlamydia rates among youth, which exceed the provincial average by 22%. STI testing reduces the disease burden, contributing to STI prevention. 1) To document youths' perceptions regarding the socio-cultural and structural forces that affect young oil/gas workers' access to STI testing; 2) to gather service providers' perspectives on sexual health service delivery for workers; and 3) to develop recommendations to improve the accessibility of STI testing. We conducted ethnographic fieldwork (8 weeks) in a remote oil/gas community, including in-depth interviews with 25 young people (ages 15-25) and 14 health and social service providers. Participants identified limited opportunities to access testing, geographic isolation, and 'rigger' culture as three key categories inhibiting STI testing among oil/gas Workers. These results suggest the need for place-based approaches to STI control. Innovative outreach strategies are suggested to address oil/gas workers' needs, including a locally tailored STI awareness campaign, condom distribution, expanded clinic hours, and onsite STI testing.

NASA Information Technology Implementation Plan

NASA Technical Reports Server (NTRS)

2000-01-01

NASA's Information Technology (IT) resources and IT support continue to be a growing and integral part of all NASA missions. Furthermore, the growing IT support requirements are becoming more complex and diverse. The following are a few examples of the growing complexity and diversity of NASA's IT environment. NASA is conducting basic IT research in the Intelligent Synthesis Environment (ISE) and Intelligent Systems (IS) Initiatives. IT security, infrastructure protection, and privacy of data are requiring more and more management attention and an increasing share of the NASA IT budget. Outsourcing of IT support is becoming a key element of NASA's IT strategy as exemplified by Outsourcing Desktop Initiative for NASA (ODIN) and the outsourcing of NASA Integrated Services Network (NISN) support. Finally, technology refresh is helping to provide improved support at lower cost. Recently the NASA Automated Data Processing (ADP) Consolidation Center (NACC) upgraded its bipolar technology computer systems with Complementary Metal Oxide Semiconductor (CMOS) technology systems. This NACC upgrade substantially reduced the hardware maintenance and software licensing costs, significantly increased system speed and capacity, and reduced customer processing costs by 11 percent.

"Manejar la Situacion": Partner Notification, Partner Management, and Conceptual Frameworks for HIV/STI Control Among MSM in Peru.

PubMed

Clark, Jesse L; Perez-Brumer, Amaya; Salazar, Ximena

2015-12-01

Previous analyses of partner notification (PN) have addressed individual, interpersonal, social, and structural issues influencing PN outcomes but have paid less attention to the conceptual framework of PN itself. We conducted 18 individual interviews and 8 group discussions, in a two-stage qualitative research process, to explore the meanings and contexts of PN for sexually transmitted infections (STI) among men who have sex with men (MSM) and men who have sex with men and women (MSMW) in Lima, Peru. Participants described PN as the open disclosure of private, potentially stigmatizing information that could strengthen or disrupt a partnership, structured by the tension between concealment and revelation. In addition to informing partners of an STI diagnosis, the act of PN was believed to reveal other potentially stigmatizing information related to sexual identity and practices such as homosexuality, promiscuity, and HIV co-infection. In this context, the potential development of visible, biological STI symptoms represented a risk for disruption of the boundary between secrecy and disclosure that could result in involuntary disclosure of STI status. To address the conflict between concealment and disclosure, participants cited efforts to "manejar la situacion" (manage the situation) by controlling the biological risks of STI exposure without openly disclosing STI status. We use this concept of "managing the situation" as a practical and theoretical framework for comprehensive Partner Management for HIV/STI control systems among MSM in Latin America.

Urinary symptoms in adolescent females: STI or UTI?

PubMed

Huppert, Jill S; Biro, Frank; Lan, Dongmei; Mortensen, Joel E; Reed, Jennifer; Slap, Gail B

2007-05-01

To determine if urinary symptoms or urinary tract infections (UTI) were associated with sexually transmitted infections (STI) and which history, clinical, and laboratory findings could distinguish these infections in symptomatic women. A cross-sectional sample of 296 sexually active females aged 14-22 years attending a hospital-based teen health center or emergency department were recruited. Genitourinary symptoms, medical and sexual history, and urinalysis results were recorded. STI was defined as a vaginal swab positive for Trichomonas vaginalis or urine nucleic acid amplification test positive for Neisseria gonorrheae or Chlamydia trachomatis. A urine culture with >10,000 colonies of a single pathogen was considered a positive UTI. In the full sample, prevalence of UTI and STI were 17% and 33%, respectively. Neither urinary symptoms nor UTI was significantly associated with STI. Further analyses are reported for the 154 (51%) with urinary symptoms: Positive urine leukocytes, more than one partner in the last three months and history of STI predicted STI. Urinalysis results identified four groups: (1) Normal urinalysis-67% had no infection; (2) Positive nitrites or protein-55% had UTI; (3) Positive leukocytes or blood-62% had STI; and (4) Both nitrites/protein and leukocytes/blood positive-28% had STI and 65% had UTI. Those without a documented UTI were more likely to have trichomoniasis than those with a UTI, and 65% of those with sterile pyuria had STI, mainly trichomoniasis or gonorrhea. Adolescent females with urinary symptoms should be tested for both UTI and STIs. Urinalysis results may be helpful to direct initial therapy.

This study aims to evaluate condom use, STI screening, and knowledge of STI symptoms among female sex workers (FSW) in Peru associated with sex work venue and a community randomized trial of STI control. One component of the Peru PREVEN intervention conducted mobile-team outreach to FSW to reduce STIs and increase condom use and access to government clinics for STI screening and evaluation. Prevalence ratios were calculated using multivariate Poisson regression models with robust standard errors, clustering by city. As-treated analyses were conducted to assess outcomes associated with reported exposure to the intervention. Care-seeking was more frequent in intervention communities, but differences were not statistically significant. FSW reporting exposure to the intervention had significantly higher likelihood of condom use, STI screening at public health clinics, and symptom recognition compared to those not exposed. Compared with street or bar-based FSW, brothel-based FSW reported significantly higher rates of condom use with last client, recent screening exams for STIs and HIV testing. Brothel-based FSW also more often reported knowledge of STIs and recognition of STI symptoms in women and in men. Interventions to promote STI-detection and prevention among FSW in Peru should consider structural or regulatory factors related to sex work venue. PMID:25941053

Preserving the Pyramid of STI Using Buckets

NASA Technical Reports Server (NTRS)

Nelson, Michael L.; Maly, Kurt

2004-01-01

The product of research projects is information. Through the life cycle of a project, information comes from many sources and takes many forms. Traditionally, this body of information is summarized in a formal publication, typically a journal article. While formal publications enjoy the benefits of peer review and technical editing, they are also often compromises in media format and length. As such, we consider a formal publication to represent an abstract to a larger body of work: a pyramid of scientific and technical information (STI). While this abstract may be sufficient for some applications, an in-depth use or analysis is likely to require the supporting layers from the pyramid. We have developed buckets to preserve this pyramid of STI. Buckets provide an archive- and protocol-independent container construct in which all related information objects can be logically grouped together, archived, and manipulated as a single object. Furthermore, buckets are active archival objects and can communicate with each other, people, or arbitrary network services. Buckets are an implementation of the Smart Object, Dumb Archive (SODA) DL model. In SODA, data objects are more important than the archives that hold them. Much of the functionality traditionally associated with archives is pushed down into the objects, such as enforcing terms and conditions, negotiating display, and content maintenance. In this paper, we discuss the motivation, design, and implication of bucket use in DLs with respect to grey literature.

Sex purchasing and associations with HIV/STI among a clinic-based sample of US men.

PubMed

Decker, Michele R; Raj, Anita; Gupta, Jhumka; Silverman, Jay G

2008-07-01

Despite high rates of human immunodeficiency virus/sexually transmitted infection (HIV/STI) among commercial sex workers and international concern that male clients may constitute a critical bridge population for HIV/STI transmission, little empirical data exist within the United States to characterize men who purchase sex or to assess their sexual risk and HIV/STI infection. The study involves the analysis of a community-based survey of men aged 18-35 years attending urban health centers (n=1515) to assess the prevalence of engagement in sex purchasing during the past year and to evaluate relations with self-reported HIV/STI diagnosis and symptoms across this same period. More than 1 in 12 (8.7%) men reported exchanging drugs, money, or a place to stay for sex with a female partner in the past year. Such behavior was associated with additional sexual risk taking and emerged as an independent predictor of self-reported HIV/STI diagnosis [adjusted odds ratio (ORadj)=2.99; 95% confidence interval (CI): 1.51 to 5.94] and STI symptoms (ORadj=2.57; 95% CI: 1.57 to 4.22) in the past year in analyses adjusted for alternate HIV/STI risk sources. Sex purchasing is a common form of HIV/STI risk among the population sampled. Men engaging in such behavior are more likely to be HIV/STI infected and, thus, represent a risk to the sexual health of both commercial and noncommercial sex partners. Further research is needed to inform interventions targeted toward male clients of prostituted women.

The NASA Integrated Information Technology Architecture

NASA Technical Reports Server (NTRS)

Baldridge, Tim

1997-01-01

This document defines an Information Technology Architecture for the National Aeronautics and Space Administration (NASA), where Information Technology (IT) refers to the hardware, software, standards, protocols and processes that enable the creation, manipulation, storage, organization and sharing of information. An architecture provides an itemization and definition of these IT structures, a view of the relationship of the structures to each other and, most importantly, an accessible view of the whole. It is a fundamental assumption of this document that a useful, interoperable and affordable IT environment is key to the execution of the core NASA scientific and project competencies and business practices. This Architecture represents the highest level system design and guideline for NASA IT related activities and has been created on the authority of the NASA Chief Information Officer (CIO) and will be maintained under the auspices of that office. It addresses all aspects of general purpose, research, administrative and scientific computing and networking throughout the NASA Agency and is applicable to all NASA administrative offices, projects, field centers and remote sites. Through the establishment of five Objectives and six Principles this Architecture provides a blueprint for all NASA IT service providers: civil service, contractor and outsourcer. The most significant of the Objectives and Principles are the commitment to customer-driven IT implementations and the commitment to a simpler, cost-efficient, standards-based, modular IT infrastructure. In order to ensure that the Architecture is presented and defined in the context of the mission, project and business goals of NASA, this Architecture consists of four layers in which each subsequent layer builds on the previous layer. They are: 1) the Business Architecture: the operational functions of the business, or Enterprise, 2) the Systems Architecture: the specific Enterprise activities within the context

NASA/DOD Aerospace Knowledge Diffusion Research Project. Paper 9: Information intermediaries and the transfer of aerospace Scientific and Technical Information (STI): A report from the field

Eveland, J. D.; Pinelli, Thomas E.

1991-01-01

From the NASA/DOD survey data, there can be no way of inferring what strategy for knowledge transfer is best; indeed, given the fact that the respondents were all presumably well qualified professionals, the data tend to call into serious question the idea that any one model might meet the needs of more than a distinct minority of possible users. The evidence to date appears to reinforce the concept that different information environments take many different shapes, and interact with each other and with formal data transmission sources in many different and equally valuable ways. Any overall strategy for improving the effectiveness and efficiency of scientific and technical information sharing must take this divergence into account, and work toward the creation of systems that reinforce true interactive knowledge utilization rather than simply disseminating data.

Ethnic and regional differences in STI clinic use: a Dutch epidemiological study using aggregated STI clinic data combined with population numbers.

Ethnic minorities (EM) from STI-endemic countries are at increased risk to acquire an STI. The objectives of this study were to investigate the difference in STI clinic consultation and positivity rates between ethnic groups, and compare findings between Dutch cities. Aggregated population numbers from 2011 to 2013 of 15-44 year-old citizens of Amsterdam, Rotterdam, The Hague and Utrecht extracted from the population register (N=3 129 941 person-years) were combined with aggregated STI clinic consultation data in these cities from the national STI surveillance database (N=113 536). Using negative binomial regression analyses (adjusted for age and gender), we compared STI consultation and positivity rates between ethnic groups and cities. Compared with ethnic Dutch (consultation rate: 40.3/1000 person-years), EM from Eastern Europe, Sub-Sahara Africa, Suriname, the Netherlands Antilles/Aruba and Latin America had higher consultation rates (range relative risk (RR): 1.27-2.26), whereas EM from Turkey, North Africa, Asia and Western countries had lower consultation rates (range RR: 0.29-0.82). Of the consultations among ethnic Dutch, 12.2% was STI positive. Positivity rates were higher among all EM groups (range RR: 1.14-1.81). Consultation rates were highest in Amsterdam and lowest in Utrecht independent of ethnic background (range RR Amsterdam vs Utrecht: 4.30-10.30). Positivity rates differed less between cities. There were substantial differences in STI clinic use between ethnic groups and cities in the Netherlands. Although higher positivity rates among EM suggest that these high-risk individuals reach STI clinics, it remains unknown whether their reach is optimal. Special attention should be given to EM with comparatively low consultation rates. Published by the BMJ Publishing Group Limited.

The purpose of this study was to apply the Rasch model on psychometric assessment of an HIV/STI sexual risk scale among men who have sex with men (MSM). A cross-sectional study using respondent driven sampling was conducted among 351 MSM in Shenzhen, China. The Rasch model was used to examine the psychometric properties of an HIV/STI sexual risk scale including nine types of sexual behaviors. The Rasch analysis of the nine items met the unidimensionality and local independence assumption. Although the person reliability was low at 0.35, the item reliability was high at 0.99. The fit statistics provided acceptable infit and outfit values. Item difficulty invariance analysis showed that the item estimates of the risk behavior items were invariant (within error). The findings suggest that the Rasch model can be utilized for measuring the level of sexual risk for HIV/STI infection as a single latent construct and for establishing the relative degree of severity of each type of sexual behavior in HIV/STI transmission and acquisition among MSM. The measurement scale provides a useful measurement tool to inform, design and evaluate behavioral interventions for HIV/STI infection among MSM.

Signaling induced by hop/STI-1 depends on endocytosis

DOE Office of Scientific and Technical Information (OSTI.GOV)

Americo, Tatiana A.; Chiarini, Luciana B.; Linden, Rafael

The co-chaperone hop/STI-1 is a ligand of the cell surface prion protein (PrP{sup C}), and their interaction leads to signaling and biological effects. Among these, hop/STI-1 induces proliferation of A172 glioblastoma cells, dependent on both PrP{sup C} and activation of the Erk pathway. We tested whether clathrin-mediated endocytosis affects signaling induced by hop/STI-1. Both hyperosmolarity induced by sucrose and monodansyl-cadaverine blocked Erk activity induced by hop/STI-1, without affecting the high basal Akt activity typical of A172. The endocytosis inhibitors also affected the sub-cellular distribution of phosphorylated Erk, consistent with blockade of the latter's activity. The data indicate that signaling inducedmore » by hop/STI-1 depends on endocytosis. These findings are consistent with a role of sub-cellular trafficking in signal transduction following engagement by PrP{sup C} by ligands such as hop/STI-1, and may help help unravel both the functions of the prion protein, as well as possible loss-of-function components of prion diseases.« less

1993-01-01

Today we are in the midst of information and 'total quality' revolutions. At the NASA STI Program's Center for AeroSpace Information (CASI), we are focused on using continuous improvements techniques to enrich today's services and products and to ensure that tomorrow's technology supports the TQM-based improvement of future STI program products and services. The Continuous Improvements Program at CASI is the foundation for Total Quality Management in products and services. The focus is customer-driven; its goal, to identify processes and procedures that can be improved and new technologies that can be integrated with the processes to gain efficiencies, provide effectiveness, and promote customer satisfaction. This Program seeks to establish quality through an iterative defect prevention approach that is based on the incorporation of standards and measurements into the processing cycle.

Men who have sex with men (MSM) are at highest risk for STIs and HIV infections in the Netherlands. However, official guidelines on STI testing among MSM are lacking. They are advised to test for STIs at least every six months, but their testing behaviour is not well known. This study aimed to get insight into the proportion and determinants of consistent 6-monthly STI testing among MSM testing at STI outpatient clinics in the Netherlands. This study included longitudinal surveillance data of STI consultations among MSM from all 26 STI outpatient clinics in the Netherlands between 1 June 2014 and 31 December 2015. Multinomial logistic regression analysis was used to identify determinants of consistent 6-monthly testing compared with single testing and inconsistent testing. Determinants of time between consultations among men with multiple consultations were analysed using a Cox Prentice-Williams-Peterson gap-time model. A total of 34 605 STI consultations of 18 634 MSM were included. 8966 (48.1%) men had more than one consultation, and 3516 (18.9%) men tested consistently 6-monthly. Indicators of high sexual risk behaviour, including having a history of STI, being HIV positive and having more than 10 sex partners, were positively associated with both being a consistent tester and returning to the STI clinic sooner. Men who were notified by a partner or who reported STI symptoms were also more likely to return to the STI clinic sooner, but were less likely to be consistent testers, identifying a group of event-driven testers. The proportion of consistent 6-monthly testers among MSM visiting Dutch STI outpatient clinics was low. Testing behaviour was associated with sexual risk behaviour, but exact motives to test consistently remain unclear. Evidence-based testing guidelines are needed to achieve optimal reductions in STI transmission in the future. Published by the BMJ Publishing Group Limited.

STI service delivery in British Columbia, Canada; providers' views of their services to youth

PubMed Central

2012-01-01

Background Little is known about service providers’ knowledge, attitudes, and experiences in relation to the assessment, diagnosis, and treatment of individuals seeking care for sexually transmitted infections (STIs), and how they influence the delivery of services. The purpose of this study was to explore the perceptions of STI care providers and the ways they approached their practice. Methods We used a qualitative approach drawing on methods used in thematic analysis. Individual semi-structured in-depth interviews were conducted with 21 service providers delivering STI services in youth clinics, STI clinics, reproductive health clinics, and community public health units in British Columbia (BC), Canada. Results Service providers’ descriptions of their activities and roles were shaped by a number of themes including specialization, scarcity, and maintaining the status quo. The analysis suggests that service providers perceive, at times, the delivery of STI care to be inefficient and inadequate. Conclusion Findings from this study identify deficits in the delivery of STI services in BC. To understand these deficits, more research is needed to examine the larger health care structure within which service providers work, and how this structure not only informs and influences the delivery of services, but also how particular structural barriers impinge on and/or restrict practice.

NASA/DOD Aerospace Knowledge Diffusion Research Project. Paper 26: The relationship between technology policy and scientific and technical information within the US and Japanese aerospace industries

NASA Technical Reports Server (NTRS)

Pinelli, Thomas E.; Barclay, Rebecca O.; Kennedy, John M.

1993-01-01

Government technology policy has nurtured the growth of the aerospace industry which is vital to both the U.S. and Japanese economies. Japanese technology policy differs significantly from U.S. technology policy, however, particularly with respect to the production, transfer, and use of scientific and technical information (STI). In this paper, we discuss the unique position of the aerospace industry in the U.S. and Japan, U.S. and Japanese aerospace policy, and the role of STI in the process of aerospace innovation. The information-seeking behaviors of U.S. and Japanese aerospace engineers and scientists are compared. The authors advocate the development of innovation-adoption technology and STI policy goals for U.S. aerospace and the inclusion of an aerospace knowledge diffusion transfer system with an 'active' component for scanning and acquiring foreign aerospace technology and STI.

NASA University Program Management Information System

2000-01-01

As basic policy, NASA believes that colleges and universities should be encouraged to participate in the nation's space and aeronautics program to the maximum extent practicable. Indeed, universities are considered as partners with government and industry in the nation's aerospace program. NASA:s objective is to have them bring their scientific, engineering, and social research competence to bear on aerospace problems and on the broader social, economic, and international implications of NASA's technical and scientific programs. It is expected that, in so doing, universities will strengthen both their research and their educational capabilities to contribute more effectively to the national well-being. NASA field codes and certain Headquarters program offices provide funds for those activities in universities which contribute to the mission needs of that particular NASA element. Although NASA has no predetermined amount of money to devote to university activities, the effort funded each year is substantial. This annual report is one means of documenting the NASA-university relationship, frequently denoted, collectively, as NASA's University Program. This report is consistent with agency accounting records, as the data is obtained from NASA:s Financial and Contractual Status (FACS) System, operated by the Financial Management Division and the Procurement Office. However, in accordance with interagency agreements, the orientation differs from that required for financial or procurement purposes. Any apparent discrepancies between this report and other NASA procurement or financial reports stem from the selection criteria for the data.* This report was prepared by the Education Division/FE, Office of Human Resources and Education, using a management information system which was modernized during FY 1993.

The project has both immediate and long term purposes. In the first instance it provides a practical and pragmatic basis for understanding how the results of NASA/DoD research diffuse into the aerospace R and D process. Over the long term it provides an empirical basis for understanding the aerospace knowledge diffusion process itself, and its implications at the individual, organizational, national, and international levels. The project is studying the major barriers to effective knowledge diffusion. This project will provide descriptive and analytical data regarding the flow of scientific and technical information (STI). It will examine both channels used to communicate information and the social system of the aerospace knowledge diffusion process.

'Not the swab!' Young men's experiences with STI testing.

PubMed

2010-01-01

In Canada, STI rates are high and rising, especially amongst young men. Meanwhile, the needs of young men regarding STI testing services are poorly understood, as are the socio-cultural and structural factors that influence young men's sexual health-seeking behaviours. To better understand this phenomenon, we draw on interviews with 45 men (ages 15-25) from British Columbia, Canada. Our research reveals how structural forces (e.g. STI testing procedures) interact with socio-cultural factors (e.g. perceptions of masculinities and feminities) to shape young men's experiences with STI testing. STI testing was characterised as both a potentially sexualised experience (e.g. fears of getting an erection during genital examinations), and as a process where young men experience multiple vulnerabilities associated with exposing the male body in clinical service sites. In response, participants drew on dominant ideals of masculinity to reaffirm their predominately hetero-normative gender identities. Despite growing up in an era where sexual health promotion efforts have been undertaken, participants did not feel they had permission to engage in discussions with other men about sexual health issues. Attending to young men's perspectives on STI testing represents a starting point in reforming our approaches to addressing how socio-cultural and structural factors shape these experiences.

Mapping HIV/STI behavioural surveillance in Europe

PubMed Central

2010-01-01

Background Used in conjunction with biological surveillance, behavioural surveillance provides data allowing for a more precise definition of HIV/STI prevention strategies. In 2008, mapping of behavioural surveillance in EU/EFTA countries was performed on behalf of the European Centre for Disease prevention and Control. Method Nine questionnaires were sent to all 31 member States and EEE/EFTA countries requesting data on the overall behavioural and second generation surveillance system and on surveillance in the general population, youth, men having sex with men (MSM), injecting drug users (IDU), sex workers (SW), migrants, people living with HIV/AIDS (PLWHA), and sexually transmitted infection (STI) clinics patients. Requested data included information on system organisation (e.g. sustainability, funding, institutionalisation), topics covered in surveys and main indicators. Results Twenty-eight of the 31 countries contacted supplied data. Sixteen countries reported an established behavioural surveillance system, and 13 a second generation surveillance system (combination of biological surveillance of HIV/AIDS and STI with behavioural surveillance). There were wide differences as regards the year of survey initiation, number of populations surveyed, data collection methods used, organisation of surveillance and coordination with biological surveillance. The populations most regularly surveyed are the general population, youth, MSM and IDU. SW, patients of STI clinics and PLWHA are surveyed less regularly and in only a small number of countries, and few countries have undertaken behavioural surveys among migrant or ethnic minorities populations. In many cases, the identification of populations with risk behaviour and the selection of populations to be included in a BS system have not been formally conducted, or are incomplete. Topics most frequently covered are similar across countries, although many different indicators are used. In most countries, sustainability

Sexually transmitted infections (STI) disproportionately impact non-Hispanic blacks. Racial residential segregation has been associated with negative socioeconomic outcomes. We sought to examine the association between segregation and STI diagnosis among blacks. The National Survey of Family Growth and US Census served as data sources. Five distinct dimensions represent segregation. The association between STI diagnosis and each segregation dimension was assessed with multilevel logistic regression modeling. 305 (7.4%) blacks reported STI diagnosis during the past 12 months. Depending on the dimension, segregation was a risk factor [dissimilarity aOR 2.41 (95% CI 2.38-2.43)] and a protective factor [isolation aOR 0.90 (95% CI 0.89-0.91)] for STI diagnosis. Findings suggest that STI diagnosis among blacks is associated with segregation. Additional research is needed to identify mechanisms for how segregation affects STI diagnosis and to aid in the development of interventions to decrease STIs.

Background/objectives The HIV prevalence in Eastern Europe and Central Asia continues to increase. While injection drug use (IDU) is leading factor, heterosexual transmission is on the rise. Little is known about female sex workers (FSWs) in the region despite the central role of commercial sex in heterosexual STI/HIV transmission globally. We evaluated the prevalence of STI/HIV among Moscow-based FSWs, and potential risk factors including IDU, sexual risks, and violence victimization. Methods Moscow-based FSWs (n=147) completed a clinic-based survey and STI/HIV testing over an eight month period in 2005. Results HIV prevalence was 4.8%, and 31.3% were infected with at least one STI including HIV. Sexual behaviors significantly associated with STI/HIV included anal sex (AOR 3.48), high client volume (three or more clients daily, AOR 2.71), recent subbotnik (sex demanded by police; AOR 2.50), and regularly being presented with more clients than initially agreed to (AOR 2.45). Past year experiences of physical violence from clients and threats of violence from pimps were associated with STI/HIV (AOR 3.14; AOR 3.65 respectively). IDU was not significantly associated with STI/HIV. Anal sex and high client volume partially mediated the associations of abuse with STI/HIV. Conclusion Findings illustrate substantial potential for heterosexual STI/HIV transmission in a setting better known for IDU-related risk. Many of the STI/HIV risks observed are not modifiable by FSWs alone. STI/HIV prevention efforts for this vulnerable population will benefit from reducing coercion and abuse perpetrated by pimps and clients. PMID:22287530

Toward global prevention of sexually transmitted infections (STIs): the need for STI vaccines.

PubMed

Gottlieb, Sami L; Low, Nicola; Newman, Lori M; Bolan, Gail; Kamb, Mary; Broutet, Nathalie

2014-03-20

An estimated 499 million curable sexually transmitted infections (STIs; gonorrhea, chlamydia, syphilis, and trichomoniasis) occurred globally in 2008. In addition, well over 500 million people are estimated to have a viral STI such as herpes simplex virus type 2 (HSV-2) or human papillomavirus (HPV) at any point in time. STIs result in a large global burden of sexual, reproductive, and maternal-child health consequences, including genital symptoms, pregnancy complications, cancer, infertility, and enhanced HIV transmission, as well as important psychosocial consequences and financial costs. STI control strategies based primarily on behavioral primary prevention and STI case management have had clear successes, but gains have not been universal. Current STI control is hampered or threatened by several behavioral, biological, and implementation challenges, including a large proportion of asymptomatic infections, lack of feasible diagnostic tests globally, antimicrobial resistance, repeat infections, and barriers to intervention access, availability, and scale-up. Vaccines against HPV and hepatitis B virus offer a new paradigm for STI control. Challenges to existing STI prevention efforts provide important reasons for working toward additional STI vaccines. We summarize the global epidemiology of STIs and STI-associated complications, examine challenges to existing STI prevention efforts, and discuss the need for new STI vaccines for future prevention efforts.

2014-01-01

Introduction Virtually no studies have examined the potential role that chronic stress, particularly the stress associated with socioeconomic (SES) strain, may play on STI risk. This study examined the association between SES-related risk at baseline to STI acquisition and reinfection over 36 months of follow-up. Methods 627 African-American female adolescents, ages 14–20 years, recruited from sexual health clinics in Atlanta, GA participated in a randomized controlled HIV prevention trial, and returned for at least 1 follow-up assessment. Following baseline assessment, 6 waves of data collection occurred prospectively over 36 months. Chronic SES-related risk was assessed as a sum of yes-no exposure to seven risk indicators. Laboratory confirmed tests for C. trachomatis and N. gonorrheoea were performed at each follow-up. Results In multivariable regression analysis, SES-related risk significantly predicted STI acquisition over 36 months (AOR = 1.22) and STI reinfection (AOR = 1.16) above and beyond other known correlates of STI. Discussion Findings demonstrate that SES-related risk was predictive of both STI acquisition and reinfection among young African-American females. They are consistent with propositions that some health disparities observed in adulthood may be linked to earlier chronically stress-inducing life experiences, particularly experiences associated with low SES conditions. Although various explanations exist for the observed connection between SES-related risk and subsequent STI acquisition and/or reinfection across 36 months of follow-up, these findings highlight the need for further research to elucidate the exact pathway(s) by which SES-related risk influences later STI acquisition in order to refine STI prevention interventions for this population.

Alcohol misuse and depressive symptoms have been linked to HIV/STI risk, but studies have rarely included Hispanic women, who have over four times greater HIV incidence than white, non-Hispanic women. Understanding the connections among alcohol misuse, depressive symptoms, and HIV/STI risks may suggest ways to meet specific needs of Hispanic women. This study's objective is to examine the relationships among alcohol misuse, depressive symptoms, and seven HIV/STI risk factors. Five hundred forty-eight US Hispanic women with intake data from a randomized trial were assessed for alcohol misuse (CAGE) and depressive symptoms (CES-D). GZLM and path analyses tested relationships between alcohol misuse or depressive symptoms and HIV/STI risk factors. Self-efficacy and condom use were not related to alcohol misuse or depressive symptoms, but only 15% of women reported consistent condom use. After controlling for demographics, women with alcohol misuse had significantly more perceived HIV/STI risk (OR = 2.15) and better HIV/STI knowledge (β = -.54); and women with depressive symptoms had significantly more perceived HIV/STI risk (OR = 1.76) and worse HIV/STI knowledge (β = .37). Interventions to increase condom use for Hispanic women are needed, regardless of mental disorders. Working with Hispanic women with alcohol misuse or depressive symptoms presents a need (and opportunity) to address issues directly related to HIV/STI risk. Women's health practitioners have an excellent opportunity to reach women by implementing regular screening programs in clinics that serve Hispanic women. For women with high depressive symptoms, poor HIV/STI knowledge should also be addressed. Future studies should test whether integrated and tailored risk reduction interventions affect these factors and lower HIV/STI risk for Hispanic women.

Sexually transmitted infections (STIs) pose a significant threat to individual and public health. They disproportionately affect adolescents and young adults. In a cross-sectional study, we assessed self-rated and factual STI knowledge in a sample of 9th graders in 13 secondary schools in Berlin, Germany. Differences by age, gender, migrant background, and school type were quantified using bivariate and multivariable analyses. A total of 1177 students in 61 classes participated. The mean age was 14.6 (SD = 0.7), 47.5% were female, and 52.9% had at least one immigrant parent. Knowledge of human immunodeficiency virus (HIV) was widespread, but other STIs were less known. For example, 46.2% had never heard of chlamydia, 10.8% knew of the HPV vaccination, and only 2.2% were aware that no cure exists for HPV infection. While boys were more likely to describe their knowledge as good, there was no general gender superiority in factual knowledge. Children of immigrants and students in the least academic schools had lower knowledge overall. Our results show that despite their particular risk to contract an STI, adolescents suffer from suboptimal levels of knowledge on STIs beyond HIV. Urgent efforts needed to improve adolescent STI knowledge in order to improve the uptake of primary and secondary prevention. PMID:29320464

Feedback from engineers and scientists in the academic and industrial community provided an assessment of the usage and perceived quality of NASA Langley generated STI and the familiarity and usage of selected NASA publications and services and identified ways to increase the accessibility of Langley STI. The questionnaire utilized both open and closed ended questions and was pretested for finalization. The questions were organized around the seven objectives for Phase IV. From a contact list of nearly 1,200 active industrial and academic researchers, approximately 600 addresses were verified. The 497 persons who agreed to participate were mailed questionnaires. The 381 completed questionnaires received by the cutoff date were analyzed. Based on the survey findings, recommendations were made for increasing the familiarity with and use of NASA and Langley STI and selected NASA publications and services. In addition, recommendations were made for increasing the accessibility of Langley STI.

Non-monogamy: risk factor for STI transmission and acquisition and determinant of STI spread in populations.

Aral, Sevgi O; Leichliter, Jami S

2010-12-01

The concept of concurrent partnerships, while theoretically appealing, has been challenged at many levels. However, non-monogamy may be an important risk factor for the acquisition and transmission of sexually transmitted infections (STI). One's own non-monogamy is a risk factor for transmitting STI to others, partners' non-monogamy is a risk factor for acquiring STI and, most importantly, mutual non-monogamy is a population level determinant of increased STI spread. This study describes the levels, distribution and correlates of non-monogamy, partners' non-monogamy and mutual non-monogamy among adult men and women in the USA. Data from the National Survey of Family Growth (NSFG) Cycle 6 were used. NSFG is a national household survey of subjects aged 15-44 years in the USA. Cochran-Mantel-Haenszel tests and χ(2) tests were used in the analysis. Among sexually active adults, 17.6% of women and 23.0% of men (an estimated 19 million) reported non-monogamy over the past 12 months in 2002. An estimated 11 million Americans (1 in 10) reported partners' non-monogamy and an estimated 8.4 million (7% of women and 10.5% of men) reported mutual non-monogamy. All three types of non-monogamy were reported more frequently by men than women. Younger age, lower education, formerly or never married status, living below the poverty level and having spent time in jail were associated with all three types of non-monogamy in general. The three types of non-monogamy may be helpful in tailoring prevention messages and targeting prevention efforts to subgroups most likely to spread infection.

Critical issues in NASA information systems

NASA Technical Reports Server (NTRS)

1987-01-01

The National Aeronautics and Space Administration has developed a globally-distributed complex of earth resources data bases since LANDSAT 1 was launched in 1972. NASA envisages considerable growth in the number, extent, and complexity of such data bases, due to the improvements expected in its remote sensing data rates, and the increasingly multidisciplinary nature of its scientific investigations. Work already has begun on information systems to support multidisciplinary research activities based on data acquired by the space station complex and other space-based and terrestrial sources. In response to a request from NASA's former Associate Administrator for Space Science and Applications, the National Research Council convened a committee in June 1985 to identify the critical issues involving information systems support to space science and applications. The committee has suggested that OSSA address four major information systems issues; centralization of management functions, interoperability of user involvement in the planning and implementation of its programs, and technology.

Susceptibility Tensor Imaging (STI) of the Brain

PubMed Central

Li, Wei; Liu, Chunlei; Duong, Timothy Q.; van Zijl, Peter C.M.; Li, Xu

2016-01-01

Susceptibility tensor imaging (STI) is a recently developed MRI technique that allows quantitative determination of orientation-independent magnetic susceptibility parameters from the dependence of gradient echo signal phase on the orientation of biological tissues with respect to the main magnetic field. By modeling the magnetic susceptibility of each voxel as a symmetric rank-2 tensor, individual magnetic susceptibility tensor elements as well as the mean magnetic susceptibility (MMS) and magnetic susceptibility anisotropy (MSA) can be determined for brain tissues that would still show orientation dependence after conventional scalar-based quantitative susceptibility mapping (QSM) to remove such dependence. Similar to diffusion tensor imaging (DTI), STI allows mapping of brain white matter fiber orientations and reconstruction of 3D white matter pathways using the principal eigenvectors of the susceptibility tensor. In contrast to diffusion anisotropy, the main determinant factor of susceptibility anisotropy in brain white matter is myelin. Another unique feature of susceptibility anisotropy of white matter is its sensitivity to gadolinium-based contrast agents. Mechanistically, MRI-observed susceptibility anisotropy is mainly attributed to the highly ordered lipid molecules in myelin sheath. STI provides a consistent interpretation of the dependence of phase and susceptibility on orientation at multiple scales. This article reviews the key experimental findings and physical theories that led to the development of STI, its practical implementations, and its applications for brain research. PMID:27120169

2012-01-01

Places where people meet new sex partners can be venues for the delivery of individual and environmental interventions that aim to reduce transmission of HIV and other sexually transmitted infections (STI). Using the Priorities for Local AIDS Control Efforts (PLACE) methodology we identified and characterized venues where people in a southeastern US city with high prevalence of both HIV and STI go to meet new sexual partners. A total of 123 community informants identified 143 public, private and commercial venues where people meet sex partners. Condoms were available at 14% of the venues, although 48% of venue representatives expressed a willingness to host HIV prevention efforts. Interviews with 373 people (229 men, 144 women) socializing at a random sample of 54 venues found high rates of HIV risk behaviors including concurrent sexual partnerships, transactional sex and illicit substance abuse. Risk behaviors were more common among those at certain venue types including those that may be overlooked by public health outreach efforts. The systematic methodology used was successful in locating venues where risky encounters are established and reveal opportunities for targeted HIV prevention and testing programs as well as research.

This slide presentation reviews the evolution of risk management (RM) at NASA. The aim of the RM approach at NASA is to promote an approach that is heuristic, proactive, and coherent across all of NASA. Risk Informed Decision Making (RIDM) is a decision making process that uses a diverse set of performance measures along with other considerations within a deliberative process to inform decision making. RIDM is invoked for key decisions such as architecture and design decisions, make-buy decisions, and budget reallocation. The RIDM process and how it relates to the continuous Risk Management (CRM) process is reviewed.

This handbook provides guidance for conducting risk-informed decision making in the context of NASA risk management (RM), with a focus on the types of direction-setting key decisions that are characteristic of the NASA program and project life cycles, and which produce derived requirements in accordance with existing systems engineering practices that flow down through the NASA organizational hierarchy. The guidance in this handbook is not meant to be prescriptive. Instead, it is meant to be general enough, and contain a sufficient diversity of examples, to enable the reader to adapt the methods as needed to the particular decision problems that he or she faces. The handbook highlights major issues to consider when making decisions in the presence of potentially significant uncertainty, so that the user is better able to recognize and avoid pitfalls that might otherwise be experienced.

Hop/STI1 modulates retinal proliferation and cell death independent of PrP{sup C}

DOE Office of Scientific and Technical Information (OSTI.GOV)

Arruda-Carvalho, Maithe; Njaine, Brian; Silveira, Mariana S.

Hop/STI1 is a co-chaperone adaptor protein for Hsp70/Hsp90 complexes. Hop/STI1 is found extracellularly and modulates cell death and differentiation through interaction with the prion protein (PrP{sup C}). Here, we investigated the expression of hop/STI1 and its role upon cell proliferation and cell death in the developing retina. Hop/STI1 is more expressed in developing rat retina than in the mature tissue. Hop/STI1 blocks retinal cell death in the neuroblastic layer (NBL) in a PrP{sup C} dependent manner, but failed to protect ganglion cells against axotomy-induced cell death. An antibody raised against hop/STI1 ({alpha}-STI1) blocked both ganglion cell and NBL cell deathmore » independent of PrP{sup C}. cAMP/PKA, ERK, PI3K and PKC signaling pathways were not involved in these effects. Hop/STI1 treatment reduced proliferation, while {alpha}-STI1 increased proliferation in the developing retina, both independent of PrP{sup C}. We conclude that hop/STI1 can modulate both proliferation and cell death in the developing retina independent of PrP{sup C}.« less

Self-reports of sensitive, socially stigmatized or illegal behavior are common in STI/HIV research, but can raise challenges in terms of data reliability and validity. The use of electronic data collection tools, including ecological momentary assessment (EMA), can increase the accuracy of this information by allowing a participant to self-administer a survey or diary entry, in their own environment, as close to the occurrence of the behavior as possible. In this paper, we evaluate the feasibility of using cell phone-based EMA as a tool for understanding sexual risk and STI among adult men and women. As part of a larger prospective clinical study on sexual risk behavior and incident STI in clinically recruited adult men and women, using study-provided cell phones, participants (N = 243) completed thrice-daily EMA diaries monitoring individual and partner-specific emotional attributes, non-sexual activities, non-coital or coital sexual behaviors, and contraceptive behaviors. Using these data, we assess feasibility in terms of participant compliance, behavior reactivity, general method acceptability and method efficacy for capturing behaviors. Participants were highly compliant with diary entry protocol and schedule: over the entire 12 study weeks, participants submitted 89.7% (54,914/61,236) of the expected diary entries, with an average of 18.86 of the 21 expected diaries (85.7%) each week. Submission did not differ substantially across gender, race/ethnicity and baseline sexually transmitted infection status. A sufficient volume and range of sexual behaviors were captured, with reporting trends in different legal and illegal behaviors showing small variation over time. Participants found the methodology to be acceptable, enjoyed and felt comfortable participating in the study. Achieving the correct medium of data collection can drastically improve, or degrade, the timeliness and quality of an individual's self-reported sexual risk behavior, which in turn, is a key

The HIV prevalence in Eastern Europe and Central Asia continues to increase. While injection drug use (IDU) is leading factor, heterosexual transmission is on the rise. Little is known about female sex workers (FSWs) in the region despite the central role of commercial sex in heterosexual sexually transmitted infection (STI)/HIV transmission globally. The authors evaluated the prevalence of STI/HIV among Moscow-based FSWs and potential risk factors including IDU, sexual risks and violence victimisation. Moscow-based FSWs (n=147) completed a clinic-based survey and STI/HIV testing over an 8-month period in 2005. HIV prevalence was 4.8%, and 31.3% were infected with at least one STI including HIV. Sexual behaviours significantly associated with STI/HIV included anal sex (adjusted odds ratio (AOR) 3.48), high client volume (three or more clients daily, AOR 2.71), recent subbotnik (sex demanded by police; AOR 2.50) and regularly being presented with more clients than initially agreed to (AOR 2.45). Past year experiences of physical violence from clients and threats of violence from pimps were associated with STI/HIV (AOR 3.14 and AOR 3.65, respectively). IDU was not significantly associated with STI/HIV. Anal sex and high client volume partially mediated the associations of abuse with STI/HIV. Findings illustrate substantial potential for heterosexual STI/HIV transmission in a setting better known for IDU-related risk. Many of the STI/HIV risks observed are not modifiable by FSWs alone. STI/HIV prevention efforts for this vulnerable population will benefit from reducing coercion and abuse perpetrated by pimps and clients.

Beyond Douching: Use of Feminine Hygiene Products and STI Risk Among Young Women

2010-01-01

Introduction Use of feminine hygiene products (feminine wipes, sprays, douches, and yeast creams) is common, yet understudied. Aim We examine the association among these genital hygiene behaviors, condom use, and STI. Methods We recruited 295 adolescent young women from primary care clinics as part of a larger longitudinal study of STI among high risk adolescents. Participants completed face-to-face interviews every three months, and provided vaginal swabs for STI testing. Main Outcome Measures Using the interview as our unit of analysis, we examined associations between genital hygiene behaviors (use of feminine wipes, feminine sprays, douches, or yeast creams), STI risk factors, and infection with C. trachomatis, N. gonorrhoeae, and T. vaginalis. Data were analyzed with repeated measures logistic models to control for multiple observations contributed by each participant. Results Participants reported douching in 25% of interviews, feminine sprays in 29%, feminine wipes in 27%, and yeast creams in19% of interviews. We observed a co-occurrence of douching, spraying and wiping. A past STI (6 months or more prior) was associated with increased likelihood of yeast cream use, and a recent STI (3 months prior) was associated with increased likelihood of feminine wipe use. Condom use was modestly associated with increased likelihood of douching. Conclusions Young women frequently use feminine hygiene products, and it is important for clinicians to inquire about use as these products may mimic or mask STI. We found no associations between douching and STI, but instead modest associations between hygiene and STI prevention, suggesting motivation for self-care. PMID:19170863

Incarcerated women are a critical population for targeted HIV/STI prevention programming; however, there is a dearth of evidence-based, genderspecific behavioral interventions for this population. Systematically adapting existing evidence-based interventions (EBIs) can help fill this gap. We illustrate the adaptation of the HIV/STI prevention EBI, Project Safe, for use among incarcerated women and delivery in prisons. Project POWER, the final adapted intervention, was developed using formative research with prison staff and administration, incarcerated and previously incarcerated women, and input of community advisory boards. Intervention delivery adaptations included: shorter, more frequent intervention sessions; booster sessions prior to and just after release; facilitator experience in prisons and counseling; and new videos. Intervention content adaptations addressed issues of empowerment, substance use, gender and power inequity in relationships, interpersonal violence, mental health, reentry, and social support. This illustration of the adaption process provides information to inform additional efforts to adapt EBIs for this underserved population.

NASA/Spacelink is a collection of NASA information and educational materials stored on a computer at the MSFC. It is provided by the NASA Educational Affairs Division and is operated by the Education Branch of the Marshall Center Public Affairs Office. It is designed to communicate with a wide variety of computers and modems, especially those most commonly found in classrooms and homes. It was made available to the public in February, 1988. The system may be accessed by educators and the public over regular telephone lines. NASA/Spacelink is free except for the cost of long distance calls. Overhauling and updating Spacelink was done to refurbish NASA/Spacelink, a very valuable resource medium. Several new classroom activities and miscellaneous topics were edited and entered into Spacelink. One of the areas that received a major overhaul (under the guidance of Amos Crisp) was the SPINOFFS BENEFITS, the great benefits resulting from America's space explorations. The Spinoff Benefits include information on a variety of topics including agriculture, communication, the computer, consumer, energy, equipment and materials, food, health, home, industry, medicine, natural resources, public services, recreation, safety, sports, and transportation.

Differences in risk behaviours between men who have sex with men (MSM) and men who have sex with both men and women (MSMW) have important implications for HIV and sexually transmitted infection (STI) transmission. We examined differences in risk behaviours, HIV/STI testing, self-reported HIV/STI diagnoses, and linkage to HIV care between MSM and MSMW across China. Participants were recruited through three MSM-focused websites in China. An online survey containing items on socio-demographics, risk behaviours, testing history, self-reported HIV/STI diagnosis, and linkage to and retention in HIV care was completed from September to October 2014. Chi square tests and logistic regression analyses were conducted. MSMW were less likely to use a condom during last anal sex (p ≤ 0.01) and more likely to engage in group sex (p ≤ 0.01) and transactional sex (p ≤ 0.01) compared to MSM. Self-reported HIV/STI testing and positivity rates between MSM and MSMW were similar. Among HIV-infected MSM, there was no difference in rates of linkage to or retention in antiretroviral therapy when comparing MSM and MSMW. Chinese MSM and MSMW may benefit from different HIV and STI intervention and prevention strategies. Achieving a successful decrease in HIV/STI epidemics among Chinese MSM and MSMW will depend on the ability of targeted and culturally congruent HIV/STI control programmes to facilitate a reduction in risk behaviours. © The Author(s) 2015.

2012-12-01

The NASA Earth Science Technology Office (ESTO) regularly makes investments for nurturing advanced concepts in information technology to enable rapid, low-cost acquisition, processing and visualization of Earth science data in support of future NASA missions and climate change research. In 2012, the National Research Council published a mid-term assessment of the 2007 decadal survey for future spacemissions supporting Earth science and applications [1]. The report stated, "Earth sciences have advanced significantly because of existing observational capabilities and the fruit of past investments, along with advances in data and information systems, computer science, and enabling technologies." The report found that NASA had responded favorably and aggressively to the decadal survey and noted the role of the recent ESTO solicitation for information systems technologies that partnered with the NASA Applied Sciences Program to support the transition into operations. NASA's future missions are key stakeholders for the ESTO technology investments. Also driving these investments is the need for the Agency to properly address questions regarding the prediction, adaptation, and eventual mitigation of climate change. The Earth Science Division has championed interdisciplinary research, recognizing that the Earth must be studied as a complete system in order toaddress key science questions [2]. Information technology investments in the low-mid technology readiness level (TRL) range play a key role in meeting these challenges. ESTO's Advanced Information Systems Technology (AIST) program invests in higher risk / higher reward technologies that solve the most challenging problems of the information processing chain. This includes the space segment, where the information pipeline begins, to the end user, where knowledge is ultimatelyadvanced. The objectives of the program are to reduce the risk, cost, size, and development time of Earth Science space-based and ground

A human immunodeficiency virus (HIV) as a biological endpoint in HIV prevention trials may not be feasible, so investigators have used surrogate biological outcomes. In a multisite trial, the epidemiology of STIs may be different across sites and preclude using one STI as the outcome. This study explored using a composite STI outcome to address that problem. The combined biological endpoint was the incidence of any of six new STIs (chlamydia, gonorrhea, trichomonas (women only), syphilis, herpes simplex virus type 2 infection and HIV) during a 24-month follow up period. We investigated how a composite STI outcome would perform compared to single and dual STI outcomes under various conditions. We simulated outcomes for four populations that represented a wide range of sex and age distributions, and STI prevalences. The simulations demonstrated that a combined biologic outcome was superior to single and dual STI outcomes in assessing intervention effects in 82 % of the cases. A composite biological outcome was effective in detecting intervention effects and might allow more investigations to incorporate multiple biological outcomes in the assessment of behavioral intervention trials for HIV prevention.

The Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) is an evolving protocol and philosophy regarding interoperability for digital libraries (DLs). Previously, "distributed searching" models were popular for DL interoperability. However, experience has shown distributed searching systems across large numbers of DLs to be difficult to maintain in an Internet environment. The OAI-PMH is a move away from distributed searching, focusing on the arguably simpler model of "metadata harvesting". We detail NASA s involvement in defining and testing the OAI-PMH and experience to date with adapting existing NASA distributed searching DLs (such as the NASA Technical Report Server) to use the OAI-PMH and metadata harvesting. We discuss some of the entirely new DL projects that the OAI-PMH has made possible, such as the Technical Report Interchange project. We explain the strategic importance of the OAI-PMH to the mission of NASA s Scientific and Technical Information Program.

The Clk/Sty protein kinase phosphorylates SR splicing factors and regulates their intranuclear distribution.

PubMed Central

Colwill, K; Pawson, T; Andrews, B; Prasad, J; Manley, J L; Bell, J C; Duncan, P I

1996-01-01

Mammalian Clk/Sty is the prototype for a family of dual specificity kinases (termed LAMMER kinases) that have been conserved in evolution, but whose physiological substrates are unknown. In a yeast two-hybrid screen, the Clk/Sty kinase specifically interacted with RNA binding proteins, particularly members of the serine/arginine-rich (SR) family of splicing factors. Clk/Sty itself has an serine/arginine-rich non-catalytic N-terminal region which is important for its association with SR splicing factors. In vitro, Clk/Sty efficiently phosphorylated the SR family member ASF/SF2 on serine residues located within its serine/arginine-rich region (the RS domain). Tryptic phosphopeptide mapping demonstrated that the sites on ASF/SF2 phosphorylated in vitro overlap with those phosphorylated in vivo. Immunofluorescence studies showed that a catalytically inactive form of Clk/Sty co-localized with SR proteins in nuclear speckles. Overexpression of the active Clk/Sty kinase caused a redistribution of SR proteins within the nucleus. These results suggest that Clk/Sty kinase directly regulates the activity and compartmentalization of SR splicing factors. Images PMID:8617202

NASA's Earth Observing Data and Information System

2009-01-01

NASA's Earth Observing System Data and Information System (EOSDIS) has been a central component of NASA Earth observation program for over 10 years. It is one of the largest civilian science information system in the US, performing ingest, archive and distribution of over 3 terabytes of data per day much of which is from NASA s flagship missions Terra, Aqua and Aura. The system supports a variety of science disciplines including polar processes, land cover change, radiation budget, and most especially global climate change. The EOSDIS data centers, collocated with centers of science discipline expertise, archive and distribute standard data products produced by science investigator-led processing systems. Key to the success of EOSDIS is the concept of core versus community requirements. EOSDIS supports a core set of services to meet specific NASA needs and relies on community-developed services to meet specific user needs. EOSDIS offers a metadata registry, ECHO (Earth Observing System Clearinghouse), through which the scientific community can easily discover and exchange NASA s Earth science data and services. Users can search, manage, and access the contents of ECHO s registries (data and services) through user-developed and community-tailored interfaces or clients. The ECHO framework has become the primary access point for cross-Data Center search-and-order of EOSDIS and other Earth Science data holdings archived at the EOSDIS data centers. ECHO s Warehouse Inventory Search Tool (WIST) is the primary web-based client for discovering and ordering cross-discipline data from the EOSDIS data centers. The architecture of the EOSDIS provides a platform for the publication, discovery, understanding and access to NASA s Earth Observation resources and allows for easy integration of new datasets. The EOSDIS also has developed several methods for incorporating socioeconomic data into its data collection. Over the years, we have developed several methods for determining

Drumright, Lydia N; Frost, Simon D W

2010-12-01

To test the use of a rapid assessment tool to determine social network size, and to test whether social networks with a high density of HIV/sexually transmitted infection (STI) or substance using persons were independent predictors of HIV and STI status among men who have sex with men (MSM) using a rapid tool for collecting network information. We interviewed 609 MSM from 14 bars in San Diego, California, USA, using an enhanced version of the Priorities for Local AIDS Control Efforts (PLACE) methodology. Social network size was assessed using a series of 19 questions of the form 'How many people do you know that have the name X?', where X included specific male and female names (eg, Keith), use illicit substances, and have HIV. Generalised linear models were used to estimate average and group-specific network sizes, and their association with HIV status, STI history and methamphetamine use. Despite possible errors in ascertaining network size, average reported network sizes were larger for larger groups. Those who reported having HIV infection or having past STI reported significantly more HIV infected and methamphetamine or popper using individuals in their social network. There was a dose-dependent effect of social network size of HIV infected individuals on self-reported HIV status, past STI and use of methamphetamine in the last 12 months, after controlling for age, ethnicity and numbers of sexual partners in the last year. Relatively simple measures of social networks are associated with HIV/STI risk, and may provide a useful tool for targeting HIV/STI surveillance and prevention.

STI in remote communities: improved and enhanced primary health care (STRIVE) study protocol: a cluster randomised controlled trial comparing ‘usual practice’ STI care to enhanced care in remote primary health care services in Australia

PubMed Central

2013-01-01

Background Despite two decades of interventions, rates of sexually transmissible infections (STI) in remote Australian Aboriginal communities remain unacceptably high. Routine notifications data from 2011 indicate rates of chlamydia and gonorrhoea among Aboriginal people in remote settings were 8 and 61 times higher respectively than in the non-Indigenous population. Methods/design STRIVE is a stepped-wedge cluster randomised trial designed to compare a sexual health quality improvement program (SHQIP) to usual STI clinical care delivered in remote primary health care services. The SHQIP is a multifaceted intervention comprising annual assessments of sexual health service delivery, implementation of a sexual health action plan, six-monthly clinical service activity data reports, regular feedback meetings with a regional coordinator, training and financial incentive payments. The trial clusters comprise either a single community or several communities grouped together based on geographic proximity and cultural ties. The primary outcomes are: prevalence of chlamydia, gonorrhoea and trichomonas in Aboriginal residents aged 16–34 years, and performance in clinical management of STIs based on best practice indicators. STRIVE will be conducted over five years comprising one and a half years of trial initiation and community consultation, three years of trial conditions, and a half year of data analysis. The trial was initiated in 68 remote Aboriginal health services in the Northern Territory, Queensland and Western Australia. Discussion STRIVE is the first cluster randomised trial in STI care in remote Aboriginal health services. The trial will provide evidence to inform future culturally appropriate STI clinical care and control strategies in communities with high STI rates.

Background Differences in risk behaviours between men who have sex with men and men who have sex with both men and women have important implications for HIV and STI transmission. We examined differences in risk behaviours, HIV/STI testing, self-reported HIV/STI diagnoses, and linkage to HIV care between men who have sex with men and men who have sex with both men and women across China. Methods Participants were recruited through three men who have sex with men-focused websites in China. An online survey containing items on socio-demographics, risk behaviours, testing history, self-reported HIV/STI diagnosis, and linkage to and retention in HIV care was completed from September to October 2014. Chi square tests and logistic regression analyses were conducted. Results Men who have sex with both men and women were less likely to use a condom during last anal sex (p ≤ 0.01) and more likely to engage in group sex (p ≤ 0.01) and transactional sex (p ≤ 0.01) compared to men who have sex with men. Self-reported HIV/STI testing and positivity rates between men who have sex with men and men who have sex with both men and women were similar. Among HIV-infected men who have sex with men, there was no difference in rates of linkage to or retention in antiretroviral therapy when comparing men who have sex with men and men who have sex with both men and women. Conclusions Chinese men who have sex with men and men who have sex with both men and women may benefit from different HIV and STI intervention and prevention strategies. Achieving a successful decrease in HIV/STI epidemics among Chinese men who have sex with men and men who have sex with both men and women will depend on the ability of targeted and culturally congruent HIV/STI control programmes to facilitate a reduction in risk behaviours.

Kutler, Paul

1998-01-01

The aerospace industry is being challenged to reduce costs and development time as well as utilize new technologies to improve product performance. Information technology (IT) is the key to providing revolutionary solutions to the challenges posed by the increasing complexity of NASA's aeronautics and space missions and the sophisticated nature of the systems that enable them. The NASA Ames vision is to develop technologies enabling the information age, expanding the frontiers of knowledge for aeronautics and space, improving America's competitive position, and inspiring future generations. Ames' missions to accomplish that vision include: 1) performing research to support the American aviation community through the unique integration of computation, experimentation, simulation and flight testing, 2) studying the health of our planet, understanding living systems in space and the origins of the universe, developing technologies for space flight, and 3) to research, develop and deliver information technologies and applications. Information technology may be defined as the use of advance computing systems to generate data, analyze data, transform data into knowledge and to use as an aid in the decision-making process. The knowledge from transformed data can be displayed in visual, virtual and multimedia environments. The decision-making process can be fully autonomous or aided by a cognitive processes, i.e., computational aids designed to leverage human capacities. IT Systems can learn as they go, developing the capability to make decisions or aid the decision making process on the basis of experiences gained using limited data inputs. In the future, information systems will be used to aid space mission synthesis, virtual aerospace system design, aid damaged aircraft during landing, perform robotic surgery, and monitor the health and status of spacecraft and planetary probes. NASA Ames through the Center of Excellence for Information Technology Office is leading the

Objectives Prior research has shown that Dutch general practitioners (GPs) do not always offer HIV testing and the number of undiagnosed HIV patients remains high. We aimed to further investigate the frequency and reasons for (not) testing for HIV and the contribution of GPs to the diagnosis of HIV infections in the Netherlands. Design Observational study. Setting (1) Dutch primary care network of 42–45 sentinel practices where report forms during sexually transmitted infection (STI)-related consultations were routinely collected, 2008–2013. (2) Dutch observational cohort with medical data of HIV-positive patients in HIV care, 2008–2013. Outcome measures The proportion of STI-related consultations in patients from high-risk groups tested for HIV, with additional information requested from GPs on HIV testing preconsultation or postconsultation for whom HIV testing was indicated, but not performed. Next, information was collected on the profile of HIV-positive patients entering specialised HIV care following diagnosis by GPs. Results Initially, an HIV test was reported (360/907) in 40% of STI-related consultations in high-risk groups. Additionally, in 26% of consultations an HIV test had been performed in previous or follow-up consultations or at different STI-care facilities. The main reasons for not testing were perceived insignificant risk; ‘too’ recent risk according to GPs or the reluctance of patients. The initiative of the patient was a strong determinant for HIV testing. GPs diagnosed about one third of all newly found cases of HIV. Compared with STI clinics, HIV-positive patients diagnosed in general practice were more likely to be older, female, heterosexual male or sub-Saharan African. Conclusions In one-third of the STI-related consultations of persons from high-risk groups, no HIV test was performed in primary care, which is lower than previously reported. Risk-based testing has intrinsic limitations and implementation of new additional

Overview of Space Science and Information Research Opportunities at NASA

Green, James L.

2000-01-01

It is not possible to review all the opportunities that NASA provides to support the Space Science Enterprise, in the short amount of time allotted for this presentation. Therefore, only a few key programs will be discussed. The programs that I will discuss will concentrate on research opportunities for faculty, graduate and postdoctoral candidates in Space Science research and information technologies at NASA. One of the most important programs for research opportunities is the NASA Research Announcement or NRA. NASA Headquarters issues NRA's on a regular basis and these cover space science and computer science activities relating to NASA missions and programs. In the Space Sciences, the most important NRA is called the "Research Opportunities in Space Science or the ROSS NRA. The ROSS NRA is composed of multiple announcements in the areas of structure and evolution of the Universe, Solar System exploration, Sun-Earth connections, and applied information systems. Another important opportunity is the Graduate Student Research Program (GSRP). The GSRP is designed to cultivate research ties between a NASA Center and the academic community through the award of fellowships to promising students in science and engineering. This program is unique since it matches the student's area of research interest with existing work being carried out at NASA. This program is for U.S. citizens who are full-time graduate students. Students who are successful have made the match between their research and the NASA employee who will act as their NASA Advisor/ Mentor. In this program, the student's research is primarily accomplished under the supervision of his faculty advisor with periodic or frequent interactions with the NASA Mentor. These interactions typically involve travel to the sponsoring NASA Center on a regular basis. The one-year fellowships are renewable for up to three years and over $20,000 per year. These and other important opportunities will be discussed.

In an era of stagnant resources for sexually transmitted infection (STI) and HIV testing clinics, and at a time of ongoing-and in some cases increasing-STI and HIV transmission, it is important to trial and evaluate novel STI/HIV testing strategies. Based on the extant literature, one such approach is express testing, which includes full STI/HIV testing (as per clinical indication and client request), altered pretest counseling, and no physical examination for both men and women. In this paper, we overview the available research about express testing, including the literature on less-invasive testing, the effects of risk reduction counseling HIV testin/HIV testing, available research on various HIV testing modalities, and the reasons people undergo such testing. Thereafter, we overview our express testing program, which includes a detailed review of our clinical processes (which are unique within the published literature). Lastly, we provide some preliminary pre-implementation data to support the proposed efficacy of express testing. Copyright © 2015 Elsevier Inc. All rights reserved.

Background This study compares the sexual behavior and HIV prevalence of men and women at social venues where people meet new sexual partners in Eastern Kinshasa with the HIV prevalence and behavior of STI treatment and antenatal clinic patients in the same area. Methods ANC clinic patients, STI clinic patients and social venue patrons were interviewed, asked to provide a blood sample onsite, and provided information about obtaining test results. All social venue patrons at all identified social venues in the study area were invited to participate. Results 1,116 pregnant women; 66 male and 229 female STI clinic patients; and 952 male and 247 female patrons of social venues were interviewed and tested. HIV prevalence ranged by group: ANC patients (4%); female venue patrons (12%); female STI patients (16%); male venue patrons (2%); and male STI patients (23%). HIV prevalence among sexworkers at social venues (29%) was higher than the prevalence among other female patrons with new or multiple partnerships (19%) or among female patrons denying sexwork (6%). However, the absolute number of infected women was higher among women reporting recent new or multiple partnerships than the smaller group of sexworkers (23 vs 18). Two-thirds of the infected female STI patients (24/36) reported no more than one sexual partner in the past year. Conclusion Improving prevention programs in Kinshasa is essential. Prevention efforts should not neglect women at social venues who do not self-identify as sexworkers but have high rates of new sexual partnerships. PMID:19525891

1991-01-01

Phase 3 of a four part study was undertaken to investigate the use of scientific and technical information (STI) in the academic aerospace community. Three questionnaires that were sent to three groups (i.e., faculty, librarians, and students) in the academic aerospace community were used. Specific attention was paid to the types of STI used and the methods in which academic users acquired STI. The focus is on the responses of two of the three groups: faculty in aerospace departments and students enrolled in the USRA-funded capstone design courses. Respondents in both groups relied heavily upon informal sources of information, although students were less inclined to regard their personal collections of STI as important. Both groups relied upon most formal sources of STI about the same, but students reported more difficulty in using the formal resources.

Human Immunodeficiency Virus (HIV)/sexually transmitted infection (STI) risk behaviors among adolescents remain significant public health concerns. Shifts in policy and advances in technology provide opportunities for researchers and clinicians to deliver and evaluate mobile-health (mHealth) prevention programs in primary care, however, research is limited. This study assessed the usability and acceptability of Storytelling 4 Empowerment-a mHealth HIV/STI and drug abuse preventive intervention app-among adolescents in primary care. Informed by principles of community-based participatory research, we recruited a purposive sample of 30 adolescents from a youth-centered community health care clinic in Southeast Michigan. The study sample is primarily African American and female. Adolescents who participated in the Storytelling 4 Empowerment intervention assessed its usability and acceptability, and self-reported their HIV/STI risk behaviors. We used a multiple-methods approach. Adolescents reported high acceptability of the content, process, and format of Storytelling 4 Empowerment, as evidenced by qualitative data and mean scores from the Session Evaluation Form for the HIV/STI and Alcohol/Drug content, overall Storytelling 4 Empowerment intervention, and Client Satisfaction Questionnaire-8. Findings indicate that Storytelling 4 Empowerment is acceptable among adolescents in primary care. A next step is to examine the effect of Storytelling 4 Empowerment on adolescent sexual risk and drug use behaviors and HIV/STI testing.

A selected, annotated bibliography of literature citations related to the design and evaluation of STI systems is presented. The use of manual and machine-readable literature searches; the review of numerous books, periodicals reports, and papers; and the selection and annotation of literature citations were required. The bibliography was produced because the information was needed to develop the methodology for the review and evaluation project, and a survey of the literature did not reveal the existence of a single published source of information pertinent to the subject. Approximately 200 citations are classified in four subject areas. The areas include information - general; information systems - design and evaluation, including information products and services; information - use and need; and information - economics.

In 2016 the World Health Assembly adopted the global strategy on Sexually Transmitted Infections (STI) 2016-2021 aiming to reduce curable STIs by 90% by 2030. We costed scaling-up priority interventions to coverage targets. Strategy-targeted declines in Chlamydia trachomatis, Neisseria gonorrhoeae, Treponema pallidum and Trichomonas vaginalis were applied to WHO-estimated regional burdens at 2012. Syndromic case management was costed for these curable STIs, symptomatic Herpes Simplex Virus 2 (HSV-2), and non-STI vaginal syndromes, with incrementally expanding etiologic diagnosis. Service unit costs were multiplied with clinic attendances and people targeted for screening or prevention, by income tier. Human papilloma virus (HPV) vaccination and screening were costed for coverage increasing to 60% of 10-year-old girls for vaccination, and 60% of women 30-49 years for twice-lifetime screening (including clinical follow-up for positive screens), by 2021. Strategy implementation will cost an estimated US$ 18.1 billion over 2016-2021 in 117 low- and middle-income countries. Cost drivers are HPV vaccination ($3.26 billion) and screening ($3.69 billion), adolescent chlamydia screening ($2.54 billion), and antenatal syphilis screening ($1.4 billion). Clinical management-of 18 million genital ulcers, 29-39 million urethral discharges and 42-53 million vaginal discharges annually-will cost $3.0 billion, including $818 million for service delivery and $1.4 billion for gonorrhea and chlamydia testing. Global costs increase from $2.6 billion to $ 4.0 billion over 2016-2021, driven by HPV services scale-up, despite vaccine price reduction. Sub-Saharan Africa, bearing 40% of curable STI burdens, covers 44% of global service needs and 30% of cost, the Western Pacific 15% of burden/need and 26% of cost, South-East Asia 20% of burden/need and 18% of cost.

Acquisition plan for Digital Document Storage (DDS) prototype system

NASA Technical Reports Server (NTRS)

1990-01-01

NASA Headquarters maintains a continuing interest in and commitment to exploring the use of new technology to support productivity improvements in meeting service requirements tasked to the NASA Scientific and Technical Information (STI) Facility, and to support cost effective approaches to the development and delivery of enhanced levels of service provided by the STI Facility. The DDS project has been pursued with this interest and commitment in mind. It is believed that DDS will provide improved archival blowback quality and service for ad hoc requests for paper copies of documents archived and serviced centrally at the STI Facility. It will also develop an operating capability to scan, digitize, store, and reproduce paper copies of 5000 NASA technical reports archived annually at the STI Facility and serviced to the user community. Additionally, it will provide NASA Headquarters and field installations with on-demand, remote, electronic retrieval of digitized, bilevel, bit mapped report images along with branched, nonsequential retrieval of report subparts.

Data lifecycle management awareness is common today; planners are more likely to consider lifecycle issues at mission start. NASA remote sensing missions are typically subject to life cycle management plans of the Distributed Active Archive Center (DAAC), and NASA invests in these national centers for the long-term safeguarding and benefit of future generations. As stewards of older missions, it is incumbent upon us to ensure that a comprehensive enough set of information is being preserved to prevent the risk for information loss. This risk is greater when the original data experts have moved on or are no longer available. Preservation of items like documentation related to processing algorithms, pre-flight calibration data, or input-output configuration parameters used in product generation, are examples of digital artifacts that are sometimes not fully preserved. This is the grey area of information preservation; the importance of these items is not always clear and requires careful consideration. Missing important metadata about intermediate steps used to derive a product could lead to serious challenges in the reproducibility of results or conclusions. Organizations are rapidly recognizing that the focus of life-cycle preservation needs to be enlarged from the strict raw data to the more encompassing arena of information lifecycle management. By understanding what constitutes information, and the complexities involved, we are better equipped to deliver longer lasting value about the original data and derived knowledge (information) from them. The NASA Earth Science Data Preservation Content Specification is an attempt to define the content necessary for long-term preservation. It requires new lifecycle infrastructure approach along with content repositories to accommodate artifacts other than just raw data. The NASA Goddard Earth Sciences Data and Information Services Center (GES DISC) setup an open-source Preservation System capable of long-term archive of

Poverty and sexual concurrency: a case study of STI risk.

PubMed

Tsui, Emma K; Leonard, Lori; Lenoir, Chavonne; Ellen, Jonathan M

2008-08-01

This paper is about sexual concurrency, or maintaining multiple sexual partnerships that overlap in time. Sexual concurrency is a concept that is used in the field of public health to explain the spread of sexually transmitted diseases. Sexual concurrency has also been proposed as a site of intervention to reduce sexually transmitted infection (STI) rates, particularly among those populations who carry the heaviest STI burden: adolescents and African Americans. In this paper, we use ethnographic data collected from a group of African American adolescents living in Baltimore to examine the socially produced configurations of risks and relationships that are obscured by the term sexual concurrency. The data we present show the limits of this concept, and suggest that structural reforms, including improvements to education, drug treatment, and work opportunities, are necessary to reduce racial disparities in STI rates.

The current supplement includes approximately 100 rock and mineral, and 375 vegetation directional reflectance spectral curves in the optical region from 0.2 to 22.0 microns. The data were categorized by subject and each curve plotted on a single graph. Each graph is fully titled to indicate curve source and indexed by subject to facilitate user retrieval from ERSIS magnetic tape records.

Creating a Canonical Scientific and Technical Information Classification System for NCSTRL+

NASA Technical Reports Server (NTRS)

Tiffany, Melissa E.; Nelson, Michael L.

1998-01-01

The purpose of this paper is to describe the new subject classification system for the NCSTRL+ project. NCSTRL+ is a canonical digital library (DL) based on the Networked Computer Science Technical Report Library (NCSTRL). The current NCSTRL+ classification system uses the NASA Scientific and Technical (STI) subject classifications, which has a bias towards the aerospace, aeronautics, and engineering disciplines. Examination of other scientific and technical information classification systems showed similar discipline-centric weaknesses. Traditional, library-oriented classification systems represented all disciplines, but were too generalized to serve the needs of a scientific and technically oriented digital library. Lack of a suitable existing classification system led to the creation of a lightweight, balanced, general classification system that allows the mapping of more specialized classification schemes into the new framework. We have developed the following classification system to give equal weight to all STI disciplines, while being compact and lightweight.

Multiple Behavior Descriptions Affect the Acquisitions of STI and STT.

McCarthy, Randy J; Wells, Brett M; Skowronski, John J; Carlston, Donal E

2017-01-01

Four studies pursued the idea that spontaneous trait inferences (STIs) involve the formation of both inferential knowledge and associative knowledge while spontaneous trait transferences (STTs) involve only the formation of associative knowledge. These studies varied the type and amount of behavioral information from which perceivers could extract trait information. Experiments 1a and 1b used a modified savings-in-relearning paradigm and demonstrated that repeated presentations of an individual and a behavior description increased the strength of association between the target and implied trait, and this effect did not depend on whether the repeated presentations involved redundant information or new information. In comparison, Experiments 2a and 2b used a trait ratings dependent variable and demonstrated that the effects of repetition were stronger for STI, but not STT, when the added information differed from information that was previously encountered, but not when it was redundant with the previously encountered information.

Limited research has evaluated interventions to reduce HIV and sexually transmitted infection (STI) vulnerability among lesbian, bisexual, and queer (LBQ) women, and other women who have sex with women. The Queer Women Conversations (QWC) study examined the effectiveness of a group-based psycho-educational HIV/STI intervention with LBQ women in Toronto and Calgary, Canada. We conducted a nonrandomized cohort pilot study. Participants completed a pre-test, post-test, and 6-week follow-up. The primary outcome was sexual risk practices, while secondary objectives included intrapersonal (self-esteem, STI knowledge, resilient coping, depression), interpersonal (safer sex self-efficacy), community (community connectedness, social support), and structural (sexual stigma, access to healthcare) factors. The study was registered at http://clinicaltrials.gov. Forty-four women (mean age 28.7 years) participated in a weekend retreat consisting of six consecutive sessions tailored for LBQ women. Sessions covered a range of topics addressing behavioral and social-structural determinants of HIV/STI risk, including STI information, safer sex negotiation skills, and addressing sexual stigma. Adjusted for socio-demographic characteristics, sexual risk practices (β2=-2.96, 95% CI -4.43, -1.50), barrier use self-efficacy (β2=1.52, 95% CI 0.51, 2.53), STI knowledge (β2=4.41, 95% CI 3.52, 5.30), and sexual stigma (β2=-2.62, 95% CI -3.48, -1.75) scores showed statistically significant changes 6 weeks post-intervention. Initial increases in safer sex self-efficacy, social support, and community connectedness were not sustained at 6-week follow up, highlighting the need for booster sessions or alternative approaches to address social factors. Study results may inform HIV/STI prevention interventions, sexual health care provision, and support services tailored for LBQ women.

Talk or text to tell? How young adults in Canada and South Africa prefer to receive STI results, counseling, and treatment updates in a wireless world.

PubMed

Labacher, Lukas; Mitchell, Claudia

2013-01-01

Young adults often lack access to confidential, long-lasting, and nonjudgmental interactions with sexual health professionals at brick-and-mortar clinics. To ensure that patients return for their STI test results, post-result counseling, and STI-related information, computer-mediated health intervention programming allows them to receive sexual health information through onsite computers, the Internet, and mobile phone calls and text messages. To determine whether young adults (age: M = 21 years) prefer to communicate with health professionals about the status of their sexual health through computer-mediated communication devices, 303 second-year university students (183 from an urban North American university and 120 from a periurban university in South Africa) completed a paper-based survey indicating how they prefer to communicate with doctors and nurses: talking face to face, mobile phone call, text message, Internet chat programs, Facebook, Twitter, or e-mail. Nearly all students, and female students in South Africa in particular, prefer to receive their STI test results, post-results counseling, and STI-related information by talking face to face with doctors and nurses rather than communicating through computers or mobile phones. Results are clarified in relation to gender, availability of various technologies, and prevalence of HIV in Canada and in South Africa.

2009-01-01

Background Syndromic management is an inexpensive and effective method for the treatment of symptomatic sexually transmitted infections (STIs), but its effectiveness as a method of STI control in at-risk populations is questionable. We sought to determine the potential utility of syndromic management as a public health strategy to control STI transmission in high-risk populations in urban Peru. Methodology We surveyed 3,285 at-risk men and women from three Peruvian cities from 2003–05. Participants were asked about the presence of genital ulcers, discharge, or dysuria in the preceding six months. Participants reporting symptoms were asked about subsequent health-seeking and partner notification behavior. Urine and vaginal swab samples were tested for Neisseria gonorrhoeae and Chlamydia trachomatis by nucleic acid testing. Serum was tested for syphilis and Herpes Simplex Virus-Type 2 antibodies. Findings Recent urogenital discharge or dysuria was reported by 42.1% of participants with gonorrhea or chlamydia versus 28.3% of participants without infection. Genital ulceration was reported by 6.2% of participants with, and 7.4% of participants without, recent syphilis. Many participants reporting symptoms continued sexual activity while symptomatic, and approximately half of all symptomatic participants sought treatment. The positive and negative predictive values of urogenital discharge or genital ulcer disease in detecting STIs that are common in the study population were 14.4% and 81.5% for chlamydia in women and 8.3% and 89.5% for syphilis among gay-identified men. Conclusions In our study, STIs among high-risk men and women in urban Peru were frequently asymptomatic and symptomatic participants often remained sexually active without seeking treatment. Additional research is needed to assess the costs and benefits of targeted, laboratory-based STI screening as part of a comprehensive STI control program in developing countries. PMID:19779620

This is the first edition of the NASA Space Geodesy Program: Catalogue of Site Information. This catalogue supersedes all previous versions of the Crustal Dynamics Project: Catalogue of Site Information, last published in May 1989. This document is prepared under the direction of the Space Geodesy and Altimetry Projects Office (SGAPO), Code 920.1, Goddard Space Flight Center. SGAPO has assumed the responsibilities of the Crustal Dynamics Project, which officially ended December 31, 1991. The catalog contains information on all NASA supported sites as well as sites from cooperating international partners. This catalog is designed to provde descriptions and occupation histories of high-accuracy geodetic measuring sites employing space-related techniques. The emphasis of the catalog has been in the past, and continues to be with this edition, station information for facilities and remote locations utilizing the Satellite Laser Ranging (SLR), Lunar Laser Ranging (LLR), and Very Long Baseline Interferometry (VLBI) techniques. With the proliferation of high-quality Global Positioning System (GPS) receivers and Doppler Orbitography and Radiopositioning Integrated by Satellite (DORIS) transponders, many co-located at established SLR and VLBI observatories, the requirement for accurate station and localized survey information for an ever broadening base of scientists and engineers has been recognized. It is our objective to provide accurate station information to scientific groups interested in these facilities.

The Skinny on Sexual Risk: The Effects of BMI on STI Incidence and Risk

PubMed Central

Arnold, Anna; Lewis, Jessica B.; Magriples, Urania; Ickovics, Jeannette R.

2011-01-01

Few studies examine the influence of body mass index (BMI) on sexual risk. The purpose of this study was to determine whether BMI among 704 young mothers (ages 14–25) related to STI incidence and sexual risk. We examined the effect of BMI groups (normal weight, overweight, and obese) at 6 months postpartum on STI incidence and risky sex (e.g., unprotected sex, multiple partners, risky and casual partner) at 12 months post-partum. At 6 months postpartum, 31% of participants were overweight and 40% were obese. Overweight women were more likely to have an STI (OR = 1.79, 95% CI = 1.11–2.89, P < .05) and a risky partner (OR = 1.64, 95% CI = 1.01–2.08, P < .05) at 12 months postpartum compared to normal weight women. However, obese women were less likely to have an STI than normal weight women (OR = .57, 95% CI = .34–.96, P < .01). BMI related to STI incidence and sexual risk behavior. Integrated approaches to weight loss and sexual risk prevention should be explored. PMID:20976536

2018-04-12

Women are disproportionately affected by HIV in many regions of the world and they represent the fastest growing demographic in the HIV epidemic. In addition, sexual violence against women is a global public health issue which increases women's vulnerability of HIV/STI acquisition. However, the relationship between sexual violence and HIV/STI risk are complex and contribute to the growing epidemic of women infected with HIV/STIs. Our purpose for this review is to examine existing HIV/STI interventions that target women who experience forced sex. Interventions designed to address women's unique needs in HIV/STI prevention are critical in reducing women's vulnerability to HIV/STIs.

Internet-accessed sexually transmitted infection testing (e-STI testing) is increasingly available as an alternative to testing in clinics. Typically this testing modality enables users to order a test kit from a virtual service (via a website or app), collect their own samples, return test samples to a laboratory, and be notified of their results by short message service (SMS) or telephone. e-STI testing is assumed to increase access to testing in comparison with face-to-face services, but the evidence is unclear. We conducted a randomised controlled trial to assess the effectiveness of an e-STI testing and results service (chlamydia, gonorrhoea, HIV, and syphilis) on STI testing uptake and STI cases diagnosed. The study took place in the London boroughs of Lambeth and Southwark. Between 24 November 2014 and 31 August 2015, we recruited 2,072 participants, aged 16-30 years, who were resident in these boroughs, had at least 1 sexual partner in the last 12 months, stated willingness to take an STI test, and had access to the internet. Those unable to provide consent and unable to read English were excluded. Participants were randomly allocated to receive 1 text message with the web link of an e-STI testing and results service (intervention group) or to receive 1 text message with the web link of a bespoke website listing the locations, contact details, and websites of 7 local sexual health clinics (control group). Participants were free to use any other services or interventions during the study period. The primary outcomes were self-reported STI testing at 6 weeks, verified by patient record checks, and self-reported STI diagnosis at 6 weeks, verified by patient record checks. Secondary outcomes were the proportion of participants prescribed treatment for an STI, time from randomisation to completion of an STI test, and time from randomisation to treatment of an STI. Participants were sent a £10 cash incentive on submission of self-reported data. We completed all

Studies document a significant association between victimization from intimate partner violence (IPV) and sexually transmitted infections (STIs) and HIV among substance using women in Russia and elsewhere, but no study has examined IPV perpetration and STI among Russian men or HIV-infected men in Eastern Europe. This study was designed to assess the association between lifetime history of IPV perpetration and STI (lifetime and current) among substance using HIV-infected men in Russia. Cross-sectional analyses were conducted with baseline data from 415 male participants enrolled in a randomized HIV intervention clinical trial [the HERMITAGE Study]. Participants were HIV-infected men reporting recent heavy alcohol use and unprotected sex in St. Petersburg, Russia. Baseline surveys assessed demographics, IPV perpetration, risk behaviors, and STI history. Current STI was assessed via blood testing for syphilis and urine testing for gonorrhea, Chlamydia and Trichomonas. Multiple logistic regression analyses were used to assess the association between history of IPV with lifetime and current STI. Participants were aged 20-57 years. Almost half of participants (46%) reported a history of IPV perpetration; 81% reported past 30-day binge alcohol use, and 43% reported past 30-day injection drug use. Past and current STI was 41% and 12%, respectively. Men reporting a history of IPV perpetration had significantly higher odds of reporting ever having an STI (AOR=1.6, 95% CI=1.1, 2.4) but lower odds of testing positive for a current STI (AOR=0.50, 95% CI=0.26, 0.96). These findings demonstrate that a history of male IPV perpetration is common in HIV-infected Russian men and associated with a history of STI. Programmatic work toward IPV prevention is needed in Russia and may be beneficial in mitigating STIs, but more research is needed to understand how and why the association between IPV and STI changes over time in this population.

Radiosensitization Effect of STI-571 on Pancreatic Cancer Cells In Vitro

DOE Office of Scientific and Technical Information (OSTI.GOV)

Chung, Hye Won; Wen, Jing; Lim, Jong-Baeck

2009-11-01

Purpose: To examine STI-571-induced radiosensitivity in human pancreatic cancer cells in vitro. Methods and Materials: Three human pancreatic cancer cell lines (Bxpc-3, Capan-1, and MiaPaCa-2) exhibiting different expression levels of c-Kit and platelet-derived growth factor receptor beta (PDGFRbeta) and showing different K-ras mutation types were used. For evaluation of the antitumor activity of STI-571 in combination with radiation, clonogenic survival assays, Western blot analysis, and the annexin V/propidium iodide assay with microscopic evaluation by 4',6-diamidino-2-phenylindole were conducted. Results: Dramatic phosphorylated (p)-c-Kit and p-PDGFRbeta attenuation, a modest dose- and time-dependent growth inhibition, and significant radiosensitization were observed after STI-571 treatment inmore » view of apoptosis, although the levels of growth inhibition and increased radiosensitization were different according to cell lines. The grades of radiosensitivity corresponded to the attenuation levels of p-c-Kit and p-PDGFRbeta by STI-571, particularly to those of p-c-Kit, and the radiosensitivity was partially affected by K-ras mutation in pancreatic cancer cells. Among downstream pathways associated with c-Kit or PDGFRbeta, p-PLCgamma was more closely related to radiosensitivity compared with p-Akt1 or p-extracellular signal-regulated kinase 1. Conclusion: STI-571 enhances radiation response in pancreatic cancer cells. This effect is affected by the attenuation levels of p-c-Kit or p-PDGFRbeta, and K-ras mutation status. Among them, p-c-Kit plays more important roles in the radiosensitivity in pancreatic cancer compared with p-PDGFRbeta or K-ras mutation status.« less

2010-01-01

To investigate the relation between partner dependence and sexual risk behavior in the context of the information-motivation-behavioral skills (IMB) model. STI clinic patients (n = 1432) completed a computerized interview assessing partner dependence, condom use, and IMB variables. Men had higher partner-dependence scores than women did. Patients reporting greater dependence reported less condom use. Gender did not moderate the partner dependence-condom-use relationship. Partner dependence did not moderate the relation between IMB constructs and condom use. Further research is needed to determine how partner dependence can be incorporated into conceptual models of safer sex behaviors.

NASA/DOD Aerospace Knowledge Diffusion Research Project. Report 7:Summary report to phase 2 respondents including frequency distributions

1991-01-01

Phase 2 of the four phase NASA/DoD Aerospace Knowledge Diffusion Research Project was undertaken to study the transfer of scientific and technical information (STI) from government to the aerospace industry and the role of librarians and technical information specialists in the transfer process. Data was collected through a self-administered mailback questionnaire. Libraries identified as holding substantial aerospace or aeronautical technical report collections were selected to receive the questionnaires. Within each library, the person responsible for the technical report was requested to answer the questionnaire. Questionnaires were returned from approx. 68 pct. of the libraries. The respondents indicated that scientists and engineer are not aware of the services available from libraries/technical information centers and that scientists and engineers also under-utilized their services. The respondents also indicated they should be more involved in the process.

2008-01-01

The importance of gender within HIV/STI prevention has become widely recognized. However, gender ideologies associated with vulnerability to HIV/STI are often examined and addressed without sufficient attention to the larger socioeconomic context within which they arise and evolve. We conducted a cross-sectional survey with 155 female, African-American adolescents recruited from two health clinics in Baltimore, Maryland. Multivariate logistic regression was utilized to assess the relationships between HIV/STI vulnerability resulting from male partner concurrency, adherence to traditional female gender norms, using a measure of hyperfemininity, and perceived socioeconomic opportunity structures. The likelihood of reported partner concurrency increased significantly among participants reporting higher levels of hyperfemininity (OR = 2.08; 95%CI = 1.01–4.30). Hyperfeminine thinking and behavior was significantly lower in the context of higher perceived socioeconomic opportunity structures (OR = 0.87; 95%CI = 0.79–0.95). Interventions seeking to promote gender equity and reduce HIV/STI may be more effective when the socioeconomic context of gender ideologies is assessed and addressed. Programs and policies to increase educational and professional opportunity structures, particularly among marginalized communities, should be actively integrated into HIV/STI prevention planning.

Hop/Sti1 – A Two-Faced Cochaperone Involved in Pattern Recognition Receptor Maturation and Viral Infection

Perception of pathogens by host pattern recognition receptors (PRRs) or R proteins is a prerequisite to promote successful immune responses. The Hsp70/Hsp90 organizing protein Hop/Sti1, a multifunctional cochaperone, has been implicated in the maturation of a receptor-like kinase (RLK) necessary for chitin sensing. However, it remains unknown whether Hop/Sti1 is generally participating in PRR genesis. Using RNA-interference (RNAi), we silenced Hop/Sti1 expression in Nicotiana tabacum to gain further insight into the role of the cochaperone in plant defense responses. As expected, transgenic plants do not respond to chitin treatment anymore. In contrast to this, trafficking and functionality of the flagellin PRR FLS2 were unaltered, suggesting a selective involvement of Hop/Sti1 during PRR maturation. Furthermore, Hop/Sti1 was identified as a cellular determinant of Potato virus Y (PVY) symptom development in tobacco, since PVY was able to accumulate to near wild-type level without provoking the usual veinal necrosis phenotype. In addition, typical antiviral host defense responses were suppressed in the transgenic plants. These data suggest that perception of PVY is dependent on Hop/Sti1-mediated receptor maturation, while viral symptoms represent a failing attempt to restrict PVY spread. In addition, Hop/Sti1 colocalized with virus-induced membrane aggregates in wild-type plants. The retention of Hop/Sti1 in potential viral replication complexes suggests a role during viral translation/replication, explaining why RNAi-lines do not exhibit increased susceptibility to PVY. This study provides evidence for a dual role of Hop/Sti1 in PRR maturation and pathogen perception as well as in promoting viral proliferation. PMID:29075278

In the last 50 years, technological advances have accelerated at a rate unprecedented in history. We are experiencing a tremendous expansion of scientific and technological effort in many directions, and the result is a fantastic increase in the accumulation of scientific and technical information (STI) and knowledge. An integral part of the research and development (R&D) process is the STI associated with it. STI is both a raw material (input) and a product (output) of this process. The topics addressed include the following: the value of STI, management of an STI program, program policy and guidance, organizational structure, data sources, training/orientation, and the current information environment.

As basic policy, NASA believes that colleges and universities should be encouraged to participate in the nation's space and aeronautics program to the maximum extent practicable. Indeed, universities are considered as partners with government and industry in the nation's aerospace program. NASA's objective is to have them bring their scientific, engineering, and social research competence to bear on aerospace problems and on the broader social, economic, and international implications of NASA's technical and scientific programs. It is expected that, in so doing, universities will strengthen both their research and their educational capabilities to contribute more effectively to the national well-being. NASA field codes and certain Headquarters program offices provide funds for those activities in universities which contribute to the mission needs of that particular NASA element. Although NASA has no predetermined amount of money to devote to university activities, the effort funded each year is substantial. (See the bar chart on the next page). This annual report is one means of documenting the NASA-university relationship, frequently denoted, collectively, as NASA's University Program. This report is consistent with agency accounting records, as the data is obtained from NASA's Financial and Contractual Status (FACS) System, operated by the Financial Management Division and the Procurement Office. However, in accordance with interagency agreements, the orientation differs from that required for financial or procurement purposes. Any apparent discrepancies between this report and other NASA procurement or financial reports stem from the selection criteria for the data.

Sexually transmitted infection (STI)/HIV prevention programs, which do not modify social structural contexts that contribute to risk of STI/HIV may fail to bring about improvements in health, particularly among groups who experience discrimination and exclusion from public life. We conducted a multilevel intervention with sex workers, including improved clinical care and community-mobilizing strategies to modify social structural factors that shape sexual behavior, to improve condom use and reduce incident STI. We followed 420 sex workers participating in the Encontros intervention in Corumbá, Brazil, between 2003 and 2005. We estimated the effect of the intervention on incident chlamydia and gonorrhea infections and condom use using generalized estimating equations and inverse probability weighting by comparing those who actively engaged in the intervention activities (exposed) with those who were less engaged (unexposed). We also determined the association of participation on reported social cohesion and participation in networks. Exposed participants had significantly higher odds of reporting consistent condom use with regular clients (odds ratio [OR]: 1.9, 95% confidence interval:1.1-3.3) and nonsignificantly increased odds with both new clients (OR: 1.6, 0.9-2.8) and nonpaying partners (OR: 1.5, 0.9-1.5). The odds of an incident STI were nonsignificantly reduced for exposed participants compared with unexposed (OR: 0.46, 0.2-1.3). Participation was significantly associated with increased perceived cohesion and participation in networks. This prospective study provides evidence that multilevel interventions with mobilizing strategies to modify aspects of the social environment can improve condom use, reduce STIs, and increase social cohesion and participation in networks among sex workers.

Objectives To investigate the relation between partner dependence and sexual risk behavior in the context of the information-motivation-behavioral skills (IMB) model. Methods STI clinic patients (n = 1432) completed a computerized interview assessing partner dependence, condom use, and IMB variables. Results Men had higher partner-dependence scores than women did. Patients reporting greater dependence reported less condom use. Gender did not moderate the partner dependence-condom-use relationship. Partner dependence did not moderate the relation between IMB constructs and condom use. Conclusions Further research is needed to determine how partner dependence can be incorporated into conceptual models of safer sex behaviors. PMID:20001183

Technical reports constitute a product, the primary means for communicating the results of research to the user. The Langley scientific and technical information (STI) review and evaluation project undertook a review of the technical report as an effective product for information communication. Style manuals describing theory and practice in technical report preparation; publication manuals covering such factors as design, layout, and type style; and copies of technical reports were obtained from industrial, academic, governmental, and research organizations. Based on an analysis of this material, criteria will be established for the report components, for the relationship of the components within the report context, and for the overall report organization. The criteria will be used as bench marks and compared with the publication standards currently used to prepare NASA technical reports.

Patterns of HIV and STI testing among MSM couples in the U.S.

Mitchell, Jason W.; Petroll, Andrew E.

2012-01-01

Background Most MSM within the U.S. acquire HIV while in a same-sex relationship. Few studies have examined HIV and STI testing rates among MSM couples. Interestingly, the patterns that MSM test for HIV while in their relationships remain largely unknown. The present study helps fill this gap in knowledge by assessing HIV testing patterns and HIV and STI testing rates from a large convenience sample of Internet-using MSM couples. Methods : The present study used a cross-sectional study design to collect dyadic data from 361 MSM couples who lived throughout the US. A novel recruitment strategy that included placing paid, targeted advertisements on Facebook enrolled both men in the couple to independently complete the confidential, electronic survey. Results Nearly half of the HIV-negative men indicated either not having been tested for HIV since their relationship started or only testing if they felt they were at risk. Few men reported testing every 3-4 months. HIV/STI testing rates varied among the sample of couples. Few men reported having been diagnosed with a recent STI. Testing patterns and rates were mostly similar, irrespective of whether UAI was practiced within and/or outside the relationship. Conclusions HIV testing and prevention services must target men who are at risk for acquiring HIV within MSM couples. To help accomplish this goal, additional research is needed to examine the specific barriers and facilitators to HIV and STI testing among MSM in couples. PMID:23060078

Purpose To examine whether improvements have been made in the delivery of STI/HIV counseling services to teen males. Methods Analysis was performed using the 1995 National Survey of Adolescent Males (N=1729, response rate=75%) and the 2002 National Survey of Family Growth (N=1121, response rate=78%), two nationally representative surveys of 15–19 year old males. Main outcome measure included discussion about STIs/HIV with a doctor/nurse. Weighted bivariate and multivariate Poisson regression analyses examined the association of outcome measures and survey year among males engaging in various types of sexual behaviors (e.g., varying partner numbers, higher risk sex) unadjusted and adjusted for sociodemographic and health care access factors. Results In 2002, STI/HIV counseling receipt in the past year was reported by one-third of males who reported 3 or more female partners, anal sex with female partners, or oral/anal sex with male partners. Only 26% of males reporting high-risk sex (e.g., sex with prostitute, person with HIV or often/always high with sex) reported STI/HIV counseling receipt. Overall, no improvements were found between 1995 and 2002 in STI/HIV counseling, even after controlling for sociodemographic and health care access factors. Conclusions Mechanisms are needed to raise the importance of STI/HIV counseling services among sexually active male teens as well as to improve health care providers’ delivery of these services.

The heat shock protein 90 plays a pivotal role in the life cycle control of Leishmania donovani promoting the fast-growing insect stage of this parasite. Equally important for insect stage growth is the co-chaperone Sti1. We show that replacement of Sti1 is only feasible in the presence of additional Sti1 transgenes indicating an essential role. To better understand the impact of Sti1 and its interaction with Hsp90, we performed a mutational analysis of Hsp90. We established that a single amino acid exchange in the Leishmania Hsp90 renders that protein resistant to the inhibitor radicicol (RAD), yet does not interfere with its functionality. Based on this RAD-resistant Hsp90, we established a combined chemical knockout/gene complementation (CKC) approach. We can show that Hsp90 function is required in both insect and mammalian life stages and that the Sti1-binding motif of Hsp90 is crucial for proliferation of insect and mammalian stages of the parasite. The Sti1-binding motif in Leishmania Hsp90 is suboptimal - optimizing the motif increased initial intracellular proliferation underscoring the importance of the Hsp90-Sti1 interaction for this important parasitic protozoan. The CKC strategy we developed will allow the future analysis of more Hsp90 domains and motifs in parasite viability and infectivity. © 2012 Blackwell Publishing Ltd.

Assessing the Value of Enhancing AirNow Data with NASA Satellite Data

We will describe the methodology and findings from a study that addressed how satellite-enhanced air quality information provided through the U.S. Environmental Protection Agency's (EPA) AirNow Satellite Data Processor (ASDP) program could contribute to greater socioeconomic benefits. This study was funded by the National Aeronautics and Space Administration (NASA) and conducted, in partnership with the EPA, by the Center for Technology in Government at the University at Albany (CTG) and Sonoma Technology, Inc. (STI). AirNow is the national repository of real-time air quality data and forecasts for the United States. While mainly a public outreach and awareness tool, AirNow relies on the same network of ground-based air quality monitors that is used by federal, state, local, and tribal governments throughout the United States. Extensive as the monitoring network is, considerable gaps exist in certain parts of the United States. Even areas with monitors considered adequate for regulatory purposes can lack information needed to resolve localized air quality issues or give forecasters sufficient confidence about the potential air quality impact of specific events. Monitors are expensive to deploy and maintain; thus, EPA is seeking other ways to improve coverage and detail. Satellite-estimated data can provide information for many places where ground monitors do not exist, and supplement ground monitors, providing additional information for use in analysis and forecasting. ASDP uses satellite-derived estimates for fine-particle pollution (PM2.5) and provides coverage for a small window of time during the day. As satellite capabilities improve in terms of different types of sensors and increased coverage throughout the day, the ASDP program is prepared to extend its scope to additional pollutants and provide greater enhancements to the ground-based networks. In this study, CTG assessed the socioeconomic benefits of air quality data at a community level through three

Weighting for sex acts to understand the spread of STI on networks.

Human sexual networks exhibit a heterogeneous structure where few individuals have many partners and many individuals have few partners. Network theory predicts that the spread of sexually transmitted infections (STI) on such networks should exhibit striking properties (e.g. rapid spread). However, these properties cannot be found in epidemiological data. Current network models typically assume a constant STI transmission risk per partnership, which is unrealistic because it implies that sexual activity is proportional to the number of partners and that individuals have the same activity with each partner. We develop a framework that allows us to weight any sexual network based on biological assumptions. Our results indicate that STI spreading on the resulting weighted networks do not have heterogeneous-related properties, which is consistent with data and earlier studies.

Is the Speech Transmission Index (STI) a robust measure of sound system speech intelligibility performance?

NASA Astrophysics Data System (ADS)

Mapp, Peter

2002-11-01

Although RaSTI is a good indicator of the speech intelligibility capability of auditoria and similar spaces, during the past 2-3 years it has been shown that RaSTI is not a robust predictor of sound system intelligibility performance. Instead, it is now recommended, within both national and international codes and standards, that full STI measurement and analysis be employed. However, new research is reported, that indicates that STI is not as flawless, nor robust as many believe. The paper highlights a number of potential error mechanisms. It is shown that the measurement technique and signal excitation stimulus can have a significant effect on the overall result and accuracy, particularly where DSP-based equipment is employed. It is also shown that in its current state of development, STI is not capable of appropriately accounting for a number of fundamental speech and system attributes, including typical sound system frequency response variations and anomalies. This is particularly shown to be the case when a system is operating under reverberant conditions. Comparisons between actual system measurements and corresponding word score data are reported where errors of up to 50 implications for VA and PA system performance verification will be discussed.

Heterosexual Casual Sex and STI Diagnosis: A Latent Class Analysis

Ann Lyons, Heidi

2017-01-01

Casual sex is common during the emerging adult life course stage, but little research has taken a person-centered approach to investigate if casual sexual behavior influences STI rates. Using a nationally representative sample and latent class analysis, results showed three distinctive latent classes. Abstainers were the least likely to have an STI, followed by the casual sex experienced, and then the casual sex risk-takers. Once other covariates were included in the model, there was no significant difference between the abstainers and casual sex experienced classes. These results highlight the need for future research to include diverse samples of emerging adults. PMID:29276549

Objectives To describe: a. the prevalence and individual and network characteristics of group sex events (GSE) and GSE attendees; and b. HIV/STI discordance among respondents who said they went to a GSE together. Methods and Design In a sociometric network study of risk partners (defined as sexual partners, persons with whom respondents attended a GSE, or drug-injection partners) in Brooklyn, NY, we recruited a high-risk sample of 465 adults. Respondents reported on GSE attendance, the characteristics of GSEs, and their own and others’ behaviors at GSEs. Sera and urines were collected and STI prevalence was assayed. Results Of the 465 participants, 36% had attended a GSE in the last year, 26% had sex during the most recent of these GSEs, and 13% had unprotected sex there. Certain subgroups (hard drug users, men who have sex with men, women who have sex with women, and sex workers) were more likely to attend and more likely to engage in risk behaviors at these events. Among 90 GSE dyads in which at least one partner named the other as someone with whom they attended a GSE in the previous three months, STI/HIV discordance was common (HSV-2: 45% of dyads, HIV: 12% of dyads, Chlamydia: 21% of dyads). Many GSEs had 10 or more participants, and multiple partnerships at GSEs were common. High attendance rates at GSEs among members of large networks may increase community vulnerability to STI/HIV, particularly since network data show that almost all members of a large sociometric risk network either had sex with a GSE attendee or had sex with someone who had sex with a GSE attended. Conclusions Self-reported GSE attendance and participation was common among this high-risk sample. STI/HIV discordance among GSE attendees was high, highlighting the potential transmission risk associated with GSEs. Research on sexual behaviors should incorporate measures of GSE behaviors as standard research protocol. Interventions should be developed to reduce transmission at GSEs. PMID

Risk factors for HIV and STI diagnosis in a community-based HIV/STI testing and counselling site for men having sex with men (MSM) in a large German city in 2011-2012.

In recent years community-based voluntary counselling and testing sites (CB-VCT) for men having sex with men (MSM) have been established in larger cities in Germany to offer more opportunities for HIV testing. Increasingly, CB-VCTs also offer testing for other bacterial sexually transmitted infections. In Hamburg, tests in CB-VCTs are offered free and anonymously. Data on demographics and sexual risk behaviours are collected with a paper questionnaire. Questionnaire data from the MSM CB-VCT in Hamburg were linked with serological test results for HIV and syphilis, and with rectal and pharyngeal swab results for gonorrhoea and chlamydia. MSM were defined as males reporting male sex partners. CB-VCT clients were characterized demographically, and associations between sexual behaviour variables and diagnosis of HIV and sexually transmitted infections (STI) were analysed by bivariate and multivariate logistic regression analysis. Among the male clients of the CB-VCT in 2011-2012 who were tested for HIV or any STI 1476 reported male sex partners. Unprotected anal intercourse (UAI) was reported as reason for testing by 61% of the clients. Forty-one of 1413 clients testing for HIV were tested positive (2.9%). Twenty-four of 1380 clients testing for syphilis required treatment (1.7%). Tests for simultaneous detection of N. gonorrhoea and Chlamydia trachomatis were conducted on 882 pharyngeal and 642 rectal swabs, revealing 58 (=6.6%) pharyngeal and 71 (=11.1%) rectal infections with one or both pathogens. In multivariate logistic regression analysis number of partners, UAI (OR=2.42) and relying on visual impression when selecting sex partners (OR = 2.92) were associated with increased risks for diagnosis of syphilis or a rectal STI. Syphilis or rectal STI diagnosis (OR=4.52) were associated with increased risk for HIV diagnosis. The MSM CB-VCT in Hamburg reaches clients at high risk for HIV and STIs. The diagnosis of syphilis or a rectal STI was associated with increased

NASA's Earth Observing System Data and Information System (EOSDIS) has been a central component of the NASA Earth observation program since the 1990's. EOSDIS manages data covering a wide range of Earth science disciplines including cryosphere, land cover change, polar processes, field campaigns, ocean surface, digital elevation, atmosphere dynamics and composition, and inter-disciplinary research, and many others. One of the key components of EOSDIS is a set of twelve discipline-based Distributed Active Archive Centers (DAACs) distributed across the United States. Managed by NASA's Earth Science Data and Information System (ESDIS) Project at Goddard Space Flight Center, these DAACs serve over 3 million users globally. The ESDIS Project provides the infrastructure support for EOSDIS, which includes other components such as the Science Investigator-led Processing systems (SIPS), common metadata and metrics management systems, specialized network systems, standards management, and centralized support for use of commercial cloud capabilities. Given the long-term requirements, and the rapid pace of information technology and changing expectations of the user community, EOSDIS has evolved continually over the past three decades. However, many challenges remain. Challenges addressed in this paper include: growing volume and variety, achieving consistency across a diverse set of data producers, managing information about a large number of datasets, migration to a cloud computing environment, optimizing data discovery and access, incorporating user feedback from a diverse community, keeping metadata updated as data collections grow and age, and ensuring that all the content needed for understanding datasets by future users is identified and preserved.

Rösti, a fried potato product, is a large contributor to acrylamide exposure locally in Switzerland. A survey of 55 dishes prepared by 51 restaurants in the city of Zurich showed that the average rösti contained 702 µg/kg acrylamide. By analysing the content of reducing sugars in the potatoes used for frying, it is shown that with simple measures, the exposure to acrylamide could easily be reduced by factor 2 or more, while even improving the culinary experience. Though rösti is a typical dish in the German-speaking areas in Switzerland, the result may be of general interest for fried potato products which are popular in large areas of Central Europe.

Scientific and technical information (STI) is a valuable resource which represents the results of large investments in research and development (R&D), and the expertise of a nation. NASA and its predecessor organizations have developed and managed the preeminent aerospace information system. We see information and information systems changing and becoming more international in scope. In Europe, consistent with joint R&D programs and a view toward a united Europe, we have seen the emergence of a European Aerospace Database concept. In addition, the development of aeronautics and astronautics in individual nations have also lead to initiatives for national aerospace databases. Considering recent technological developments in information science and technology, as well as the reality of scarce resources in all nations, it is time to reconsider the mutually beneficial possibilities offered by cooperation and international resource sharing. The new possibilities offered through cooperation among the various aerospace database efforts toward an international aerospace database initiative which can optimize the cost/benefit equation for all participants are considered.

Chlamydia infections are common in both men and women, are often asymptomatic and can cause serious complications. Repeat testing in high-risk groups is therefore indicated. In the Netherlands, guidelines on repeat chlamydia testing differ between testing facilities, and knowledge on repeat testing behaviour is limited. Here, we analyse the current repeat testing behaviour of heterosexual STI clinic visitors, and aim to identify groups for which repeat testing advice could be advantageous. Longitudinal surveillance data from all Dutch STI outpatient clinics were used, which included all STI clinic consultations carried out among heterosexual men and women between June 2014 and December 2015. Repeat testing was defined as returning to the same STI clinic between 35 days and 12 months after initial consultation. We calculated chlamydia positivity at repeat test stratified by initial test result and time between consultations. Logistic regression analyses were used to identify predictors of repeat testing, and predictors of having a chlamydia positive repeat test. In total, 140,486 consultations in 75,487 women and 46,286 men were available for analyses. Overall, 15.4% of women and 11.1% of men returned to the STI clinic within the study period. Highest chlamydia positivity at repeat test was seen 3-5 months after initial positive test. Among both women and men, repeat testing was associated with non-Western ethnicity, having had more than two sex partners in the past 6 months, reporting STI symptoms, having a history of STI, and having a chlamydia positive initial test. Among repeat testers, chlamydia positive repeat test was most strongly associated with younger age, followed by a chlamydia positive initial test. Repeat testing most often resulted in a positive test result among young heterosexuals (<25) and heterosexuals of any age with a chlamydia infection at the initial consultation. Further efforts are needed to determine optimal repeat testing strategies.

STI571 (imatinib mesylate; Gleevec) is a selective inhibitor of the bcr-abl, c-kit, and platelet-derived growth factor receptor tyrosine kinases. Mild periorbital edema has been noted as a common side effect in Phase I and II trials of this drug for the treatment of patients with chronic myelogenous leukemia and gastrointestinal stromal tumors. The authors report the case of male patient age 63 years who developed severe periorbital edema after treatment with STI571 for chronic myelogenous leukemia. His edema was severe enough to cause visual obstruction due to lower eyelid festoons that ultimately required surgical debulking. Histopathologic analysis of specimens of the excised upper and lower eyelid tissue revealed dermal dendrocytes that expressed the platelet-derived growth factor receptor and c-kit tyrosine kinases, suggesting a possible role for dermal dendrocytes in the development of this toxic effect.

While the conditions in emergency humanitarian and conflict-affected settings often result in significant sex work economies, there is limited information on the social and structural conditions of sex work in these settings, and the impacts on HIV/STI prevention and access to sexual and reproductive health (SRH) services for sex workers. Our objective was to comprehensively review existing evidence on HIV/STI prevention and access to SRH services for sex workers in conflict-affected settings globally. We conducted a comprehensive review of all peer review (both epidemiological and qualitative) and grey literature published in the last 15 years (2000-2015), focusing on 1) HIV/STI vulnerability or prevention, and/or 2) access to SRH services for sex workers in conflict-affected settings. Five databases were searched, using combinations of sex work, conflict/mobility, HIV/STI, and SRH service terms. Relevant peer-reviewed and grey literature were also hand-searched, and key papers were cross-referenced for additional material. Five hundred fifty one records were screened and 416 records reviewed. Of 33 records describing HIV/STI prevention and/or access to SRH services among sex workers in conflict-affected settings, 24 were from sub-Saharan Africa; 18 studies described the results of primary research (13 quantitative, 3 qualitative, 2 mixed-methods) and 15 were non-primary research (e.g., commentaries, policy reports, programmatic manuals). Available evidence indicated that within conflict-affected settings, SWs' capacity to engage in HIV/STI prevention and access SRH services is severely undermined by social and structural determinants including widespread violence and human rights violations, the collapse of livelihoods and traditional social structures, high levels of displacement, and difficulties accessing already scant health services due to stigma, discrimination and criminalization. This review identified significant gaps in HIV/STI and SRH research, policy

To identify salient behavioral determinants related to STI testing among college students by testing a model based on the integrative model of behavioral (IMBP) prediction. 265 undergraduate students from a large university in the Southeastern US. Formative and survey research to test an IMBP-based model that explores the relationships between determinants and STI testing intention and behavior. Results of path analyses supported a model in which attitudinal beliefs predicted intention and intention predicted behavior. Normative beliefs and behavioral control beliefs were not significant in the model; however, select individual normative and control beliefs were significantly correlated with intention and behavior. Attitudinal beliefs are the strongest predictor of STI testing intention and behavior. Future efforts to increase STI testing rates should identify and target salient attitudinal beliefs.

Accessing Wind Tunnels From NASA's Information Power Grid

Becker, Jeff; Biegel, Bryan (Technical Monitor)

2002-01-01

The NASA Ames wind tunnel customers are one of the first users of the Information Power Grid (IPG) storage system at the NASA Advanced Supercomputing Division. We wanted to be able to store their data on the IPG so that it could be accessed remotely in a secure but timely fashion. In addition, incorporation into the IPG allows future use of grid computational resources, e.g., for post-processing of data, or to do side-by-side CFD validation. In this paper, we describe the integration of grid data access mechanisms with the existing DARWIN web-based system that is used to access wind tunnel test data. We also show that the combined system has reasonable performance: wind tunnel data may be retrieved at 50Mbits/s over a 100 base T network connected to the IPG storage server.

Condoms and sexual health education as evidence: impact of criminalization of in-call venues and managers on migrant sex workers access to HIV/STI prevention in a Canadian setting.

2016-11-17

Despite a large body of evidence globally demonstrating that the criminalization of sex workers increases HIV/STI risks, we know far less about the impact of criminalization and policing of managers and in-call establishments on HIV/STI prevention among sex workers, and even less so among migrant sex workers. Analysis draws on ethnographic fieldwork and 46 qualitative interviews with migrant sex workers, managers and business owners of in-call sex work venues in Metro Vancouver, Canada. The criminalization of in-call venues and third parties explicitly limits sex workers' access to HIV/STI prevention, including manager restrictions on condoms and limited onsite access to sexual health information and HIV/STI testing. With limited labour protections and socio-cultural barriers, criminalization and policing undermine the health and human rights of migrant sex workers working in -call venues. This research supports growing evidence-based calls for decriminalization of sex work, including the removal of criminal sanctions targeting third parties and in-call venues, alongside programs and policies that better protect the working conditions of migrant sex workers as critical to HIV/STI prevention and human rights.

2014-12-01

NASA's Earth Science Technology Office (ESTO) manages a wide range of information technology projects under the Advanced Information Systems Technology (AIST) Program. The AIST Program aims to support all phases of NASA's Earth Science program with the goal of enabling new observations and information products, increasing the accessibility and use of Earth observations, and reducing the risk and cost of satellite and ground based information systems. Recent initiatives feature computational technologies to improve information extracted from data streams or model outputs and researchers' tools for Big Data analytics. Data-centric technologies enable research communities to facilitate collaboration and increase the speed with which results are produced and published. In the future NASA anticipates more small satellites (e.g., CubeSats), mobile drones and ground-based in-situ sensors will advance the state-of-the-art regarding how scientific observations are performed, given the flexibility, cost and deployment advantages of new operations technologies. This paper reviews the success of the program and the lessons learned. Infusion of these technologies is challenging and the paper discusses the obstacles and strategies to adoption by the earth science research and application efforts. It also describes alternative perspectives for the future program direction and for realizing the value in the steps to transform observations from sensors to data, to information, and to knowledge, namely: sensor measurement concepts development; data acquisition and management; data product generation; and data exploitation for science and applications.

The effects of pattern density on CMP characteristics were investigated using specially designed wafer for the characterization of pattern-dependencies in STI CMP [1]. The purpose of this study is to investigate the planarization behavior based on a direct STI CMP used in cerium (CeO2) based slurry system in terms of pattern density variation. The minimal design rule (DR) of 180nm generation technology node was adopted for the mask layout. The mask was successfully applied for evaluation of a cerium (CeO2) abrasive based direct STI CMP process. In this study, we described a planarization behavior of the loading-effects of pattern density variation which were characterized with layout pattern density and pitch variations using masks mentioned above. Furthermore, the characterizing pattern dependent on the variations of the dimensions and spacing features, in thickness remaining after CMP, were analyzed and evaluated. The goal was to establish a concept of library method which will be used to generate design rules reducing the probability of CMP-related failures. Details of the characterization were measured in various layouts showing different pattern density ranges and the effects of pattern density on STI CMP has been discussed in this paper.

An Information NEXUS: The NASA Global Hawk Link Module

The Link Module described in this paper was first developed for the NASA Global Hawk Pacific Mission (GloPAC), four flights of 30 hour duration, supporting the Aura Validation Experiment (AVE). Its second use was during the Genesis and Rapid Intensification Processes (GRIP) experiment, a NASA Earth Science field experiment to better understand how tropical storms form and develop into major hurricanes. In these missions, the Link module negotiated all communication over the high bandwidth Ku satellite link, archived al the science data from onboard experiments in a spatially enable database, routed command and control of the instruments from the Global Hawk Operations Center, and retransmitted select data sets directly to experimenters control and analysis systems. The availability of aggregated information from collections of sensors, and remote control capabilities, in real-time, is revolutionizing the way Airborne Science is being conducted. Also described is the next generation Link Module now being designed and tested to support the NASA Earth Venture missions, the Hurricane and Severe Storm Sentinel (HS3) mission, and Airborne Tropical Tropopause Experiment (ATTREX) mission. Advanced data fusion technologies being developed will further advance the Scientific productivity, flexibility and robustness of these systems. Historically, the Link module evolved from the instrument and communication interface controller used by NASA's Pathfinder and Pathfinder plus solar powered UAS's in the late 1990's. It later was expanded for use in the AIRDAS four channel scanner flown on the NASA Altus UAS, and then again to a module in the AMS twelve channel multispectral scanner flying on the NASA (Predator-b) Ikhana UAS. The current system is the next step in the evolution, a multi board system packaged in a Curtiss Wright MIL-spec, flight qualified enclosure.

PASHA: facilitating the replication and use of effective adolescent pregnancy and STI/HIV prevention programs.

PubMed

Card, Josefina J; Lessard, Laura; Benner, Tabitha

2007-03-01

It is important that interventions that have been shown effective in changing risky behavior be disseminated, so that they can be replicated (implemented in a new site) and so that their effectiveness in a new setting can be investigated. This article provides an update on an innovative resource for promoting the replication of effective teen pregnancy and STI/HIV prevention programs. The resource is called the Program Archive on Sexuality, Health & Adolescence (PASHA). A Scientist Expert Panel rates candidate adolescent pregnancy and STI/HIV prevention programs based on the strength of the evidence of their effectiveness in changing risky sexual behavior among youth ages 10-19 (10-21 for STI/HIV prevention programs). Developers of selected programs are invited to make their program and evaluation materials publicly available through PASHA. PASHA publishes and disseminates replication kits for programs it successfully acquires. Fifty-six programs have been selected by PASHA's Scientist Expert Panel as "effective" in changing one or more risky behaviors associated with adolescent pregnancy or STI/HIV. Complete program and evaluation materials from 35 of these programs are now currently available through PASHA, five are pending, 12 are publicly available from other sources, and only four are not publicly available. PASHA programs are aimed at a diverse target population and cover diverse content on many abstinence and contraception/condom-related topics. Many pedagogical techniques are used to effect behavior change, noticeably role play and group discussion. PASHA illustrates well the productive research-to-practice feedback loop that is the backbone of "translation research." The resource can be used by adolescent pregnancy and STI/HIV prevention practitioners to put what works to work to continue the lowering of the nation's adolescent pregnancy and STI/HIV rates.

To investigate teen dating violence (TDV) perpetration (physical, sexual or psychological violence) and association with STI and related sexual risk behaviours among urban male adolescents. Adolescent male survey participants (N=134) were aged 14-20 years, recruited from urban health centres. Using crude and adjusted logistic regression, TDV perpetration was examined in relation to self-reported: STI, having sex with another person when they were only supposed to have sex with their main partner, and consistent condom use. Over one-third of males (45%) reported any TDV; 42% reported sexual violence perpetration, 13% reported perpetrating physical violence against a dating/sexual partner and 11% reported psychological violence, including threats of physical or sexual violence. Approximately 15% of males reported having ever had an STI, one quarter reported having sex with another person when they were only supposed to have sex with their main partner and 36% reported consistent condom use (past 3 months). In adjusted logistic regression models, TDV perpetration was significantly associated with self-reports of an STI (OR=3.3; 95% CI 1.2 to 9.2) and having sex with another person when they were supposed to be only having sex with their main partner (OR=4.8; 95% CI 2.0 to 11.4). There was no significant association between TDV perpetration and consistent condom use. Current study findings are the first within the literature on adolescents to suggest that greater STI and sexual risk behaviours among male adolescents perpetrating TDV may be one mechanism explaining increased STI among female adolescents reporting TDV victimisation.

Ramapriyan, H. K.

2013-12-01

NASA's Earth Observing System Data and Information System (EOSDIS) has been operational since August 1994, processing, archiving and distributing data from a variety of Earth science missions. The data sources include instruments on-board satellites and aircraft and field campaigns. In addition, EOSDIS manages socio-economic data. The satellite missions whose data are managed by EOSDIS range from the Nimbus series of the 1960s and 1970s to the EOS series launched during 1997 through 2004 to the Suomi National Polar Partnership (SNPP) launched in October 2011. Data from future satellite missions such as the Decadal Survey missions will also be archived and distributed by EOSDIS. NASA is not legislatively mandated to preserve data permanently as are other agencies such as USGS, NOAA and NARA. However, NASA must preserve all the data and associated content beyond the lives of NASA's missions to meet NASA's near-term objective of supporting active scientific research. Also, NASA must ensure that the data and associated content are preserved for transition to permanent archival agencies. The term preservation implies ensuring long-term protection of bits, readability, understandability, usability and reproducibility of results. To ensure preservation of bits, EOSDIS makes sure that data are backed-up adequately. Periodically, the risk of data loss is assessed and corrective action is taken as needed. Data are copied to more modern media on a routine basis to ensure readability. For some of the oldest data within EOSDIS, we have had to go through special data rescue efforts. Data from very old media have been restored and film data have been scanned and digitized. For example, restored data from the Nimbus missions are available for ftp access at the Goddard Earth Sciences Data and Information Services Center (GES DISC). The Earth Science Data and Information System Project, which is responsible for EOSDIS, has been active within the Data Stewardship and Preservation

Young men who have sex with men (YMSM) are at increased risk for HIV and STI infection. While encouraging HIV and STI testing among YMSM remains a public health priority, we know little about the cultural competency of providers offering HIV/STI tests to YMSM in public clinics. As part of a larger intervention study, we employed a mystery shopper methodology to evaluate the LGBT cultural competency and quality of services offered in HIV and STI testing sites in Southeast Michigan (n = 43).We trained and deployed mystery shoppers (n = 5) to evaluate the HIV and STI testing sites by undergoing routine HIV/STI testing. Two shoppers visited each site, recording their experiences using a checklist that assessed 13 domains, including the clinic’s structural characteristics and interactions with testing providers. We used the site scores to examine the checklist’s psychometric properties and tested whether site evaluations differed between sites only offering HIV testing (n = 14) versus those offering comprehensive HIV/STI testing (n = 29). On average, site scores were positive across domains. In bivariate comparisons by type of testing site, HIV testing sites were more likely than comprehensive HIV/STI testing clinics to ascertain experiences of intimate partner violence, offer action steps to achieve safer sex goals, and provide safer sex education. The developed checklist may be used as a quality assurance indicator to measure HIV/STI testing sites’ performance when working with YMSM. Our findings also underscore the need to bolster providers’ provision of safer sex education and behavioral counseling within comprehensive HIV/STI testing sites. PMID:26303197

Background/Objectives Adolescent and young adult women are at high risk for both STI/HIV and intimate partner violence (IPV). We evaluate the prevalence of IPV in the past three months and its associations with STI/HIV risk, STI, and related care-seeking over the same time period. Methods Female family planning clinic patients ages 16–29 (n=3,504) participated in a cross-sectional survey in 2011–2012 as a baseline assessment for an intervention study. We examined associations of recent IPV with sexual and drug-related STI/HIV risk behavior, self-reported STI, and STI-related clinical care seeking via logistic regression. Results Recent physical or sexual IPV (prevalence 11%) was associated with recent sexual and drug-related STI/HIV risk, specifically unprotected vaginal sex (AOR 1.93, 95% CI 1.52, 2.44), unprotected anal sex (AOR 2.22, 95% CI 1.51, 3.27) and injection drug use, both their own (AOR 3.39, 95% CI 1.47, 7.79) and their partner’s (AOR 3.85, 1.91, 7.75). IPV was also linked with coercive sexual risk: involuntary condom non-use (AOR 1.87, 95% CI 1.51, 2.33), and fears of requesting condoms (AOR 4.15, 95% CI 2.73, 6.30) and refusing sex (AOR 11.84, 95% CI 7.59, 18.45). STI-related care-seeking was also more common among those abused (AOR 2.49, 95% CI 1.87, 3.31). Conclusions Recent IPV is concurrent with sexual and drug-related STI/HIV risk, including coercive sexual risk, thus compromising women’s agency in STI/HIV risk reduction. Clinical risk assessments should broaden to include unprotected heterosexual anal sex, coercive sexual risk, and IPV, and should promote safety and harm reduction. PMID:24234072

Objectives To examine (1) whether onset of sexually transmitted infections (STI) through age 30 differed for youths who received a social developmental intervention during elementary grades compared to those in the control condition; (2) potential social-developmental mediators of this intervention; and (3) the extent to which these results differed by ethnicity. Design A nonrandomized controlled trial followed participants to age 30, 18 years after the intervention ended. Three intervention conditions were compared: a full intervention group, assigned to intervention in grades 1 through 6; a late intervention group, assigned to intervention in grades 5 and 6 only; and a no-treatment control group. Setting Eighteen public elementary schools serving diverse neighborhoods including high-crime neighborhoods of Seattle. Analysis Sample 608 participants in three intervention conditions interviewed from age 10 through 30. Interventions Teacher training in classroom instruction and management, child social and emotional skill development, and parent workshops. Outcome Cumulative onset of participant report of STI diagnosis. Intervention Mechanisms Adolescent family environment, bonding to school, antisocial peer affiliation, early sex initiation, alcohol use, cigarette use, and marijuana use were tested. Analysis and Results Complementary log-log survival analysis found significantly lower odds of STI onset for the full intervention compared to the control condition. The lowering of STI onset risk was significantly greater for African Americans and Asian Americans compared to European Americans. Family environment, school bonding and delayed initiation of sexual behavior mediated the relationship between treatment and STI hazard. Conclusions A universal intervention for urban elementary school children, focused on classroom management and instruction, children’s social competence, and parenting practices may reduce the onset of STI through age 30, especially for African

The possibility of using federally funded scientific and technical information (STI) to increase U.S. industrial innovation and productivity is discussed. The history of federally funded research and development in the fields of agriculture and aviation is reviewed as an example of successful government-sponsored research. Issues related to the production and utilization of information are considered and federal STI policy is outlined. Issues related to the transfer of knowledge between government agencies and industry are examined and a model depicting the transfer of STI in aerospace research and development is presented. Also, consideration is given to the problem of open communication versus restricted access to STI.

Young men who have sex with men (YMSM) are at increased risk for HIV and STI infection. While encouraging HIV and STI testing among YMSM remains a public health priority, we know little about the cultural competency of providers offering HIV/STI tests to YMSM in public clinics. As part of a larger intervention study, we employed a mystery shopper methodology to evaluate the LGBT cultural competency and quality of services offered in HIV and STI testing sites in Southeast Michigan (n = 43).We trained and deployed mystery shoppers (n = 5) to evaluate the HIV and STI testing sites by undergoing routine HIV/STI testing. Two shoppers visited each site, recording their experiences using a checklist that assessed 13 domains, including the clinic's structural characteristics and interactions with testing providers. We used the site scores to examine the checklist's psychometric properties and tested whether site evaluations differed between sites only offering HIV testing (n = 14) versus those offering comprehensive HIV/STI testing (n = 29). On average, site scores were positive across domains. In bivariate comparisons by type of testing site, HIV testing sites were more likely than comprehensive HIV/STI testing clinics to ascertain experiences of intimate partner violence, offer action steps to achieve safer sex goals, and provide safer sex education. The developed checklist may be used as a quality assurance indicator to measure HIV/STI testing sites' performance when working with YMSM. Our findings also underscore the need to bolster providers' provision of safer sex education and behavioral counseling within comprehensive HIV/STI testing sites.

Primary and secondary prevention are essential components of the response to HIV and sexually transmitted infections (STIs). We present findings from nationally implemented HIV/STI prevention interventions. In 2003, of those attending STI clinics at least 64% of men who have sex with men (MSM) and 55% of heterosexuals accepted a confidential HIV test; 88% of all HIV infections in women giving birth in England were diagnosed before delivery; 85% of MSM eligible for hepatitis B vaccination received a first dose of vaccine at their first STI clinic attendance; 74% of STI clinic attendees for emergency appointments, and 20% of those for routine appointments were seen within 48 hours of initiating an appointment; the National Chlamydia Screening Programme in England found a positivity of 10% and 13% among young asymptomatic women and men, respectively. Prevention initiatives have seen recent successes in limiting further HIV/STI transmission. However, more work is required if current levels of transmission are to be reduced. PMID:16461593

Foreign travellers and men who have sex with men (MSM) are prioritised groups for human immunodeficiency virus/sexually transmitted infection (HIV/STI) prevention efforts in Sweden because of high prevalence of sexual risk-taking. This study aims to describe experiences of and attitudes towards HIV/STI prevention efforts, prior to travelling abroad, among MSM, and to investigate the kinds of prevention efforts that are desirable. The study is based on survey responses from 656 MSM who had travelled abroad. Recruitment took place through a Nordic website, and had a cross-sectional design. The analysis has mainly been descriptive, but bivariate analyses were performed using the chi-square test. The level of significance was p <.05. Only a few of the participants had encountered HIV/STI prevention efforts in Sweden (5%) and abroad (23%), and a majority (58%) felt that it should be more prevalent. Having free access to condoms and lubricants was preferred among 68% of the men. Furthermore, having written information, as opposed to oral, was also preferred (68% vs. 26%). MSM felt that it was easy to find out information (79%) and claimed they would use the Internet to do so (87%). Service providers who offer their services to travellers are encouraged to provide helpful links to information about sexual health. Information that is geared towards risk groups such as young adults should be presented with awareness that MSM are also part of that group. It is important for information to be conveyed respectfully to everyone, but perhaps MSM in particular, since they may have experienced feelings of being stigmatised or discriminated against previously. © 2015 the Nordic Societies of Public Health.

NASA's experience in the international exchange of scientific and technical information in the aerospace field

1990-01-01

The early NASA international scientific and technical information exchange arrangements were usually detailed in correspondence with the librarians of the institutions involved. While this type of exchange grew to include some 200 organizations in 43 countries, NASA's main focus shifted to the relationship with the European Space Agency (ESA), which began in 1964. The NASA/ESA Tripartite Exchange Program provides more than 4000 technical reports from the NASA-produced Aerospace Database. The experience in the evolving cooperation between NASA and ESA has established the model for more recent exchange agreements with Israel, Australia, and Canada. The results of these agreements are made available to participating European organizations through the NASA File.

MINIS: Multipurpose Interactive NASA Information System

NASA Technical Reports Server (NTRS)

1976-01-01

The Multipurpose Interactive NASA Information Systems (MINIS) was developed in response to the need for a data management system capable of operation on several different minicomputer systems. The desired system had to be capable of performing the functions of a LANDSAT photo descriptive data retrieval system while remaining general in terms of other acceptable user definable data bases. The system also had to be capable of performing data base updates and providing user-formatted output reports. The resultant MINI System provides all of these capabilities and several other features to complement the data management system. The MINI System is currently implemented on two minicomputer systems and is in the process of being installed on another minicomputer system. The MINIS is operational on four different data bases.

In addition to the Environmental Geographic Information System (EGIS) presentation, we will present two live demonstrations of a portion of the work being performed in support of environmental operations onsite and NASA-wide. These live demonstrations will showcase the NASA EGIS database through working versions of two software packages available from Environmental Systems Research Institute, Inc. (ESRI, Inc.): ArcIMS 3.0 and either ArcView 3.2a or ArcGIS 8.0.2. Using a standard web browser, the ArcIMS demo will allow users to access a project file containing several data layers found in the EGIS database. ArcIMS is configured so that a single computer can be used as the data server and as the user interface, which allows for maximum Internet security because the computer being used will not actually be connected to the World Wide Web. Further, being independent of the Internet, the demo will run at an increased speed. This demo will include several data layers that are specific to Stennis Space Center. The EGIS database demo is a representative portion of the entire EGIS project sent to NASA Headquarters last year. This demo contains data files that are readily available at various government agency Web sites for download. Although these files contain roads, rails, and other infrastructure details, they are generalized and at a small enough scale that they provide only a general idea of each NASA center's surroundings rather than specific details of the area.

1993-01-01

The NASA/DoD Aerospace Knowledge Diffusion Research Project attempts to understand the information environment in which U.S. aerospace engineers and scientists work, the information-seeking behavior of U.S. aerospace engineers and scientists, and the factors that influence the use of scientific and technical information (STI) (Pinelli, Barclay, and Kennedy, 1991). Such an understanding could (1) lead to the development of practical theory, (2) contribute to the design and development of aerospace information systems, and (3) have practical implications for transferring the results of federally funded aerospace research and development (R&D) to the U.S. aerospace community. This paper presents data from two information-seeking behavior studies involving U.S. aerospace engineers and scientists that were undertaken as Phase 1 activities of the NASA/DoD Aerospace Knowledge Diffusion Research Project. Responses from three groups of respondents - DoD, other government, and industry - are presented for two sets of selected questions. One set focuses on DoD technical reports: their use and importance, reasons for non-use, the factors affecting their use, the sources used to find out about them and the sources used to physically obtain them, and the quality of DoD technical reports. The second set focuses on information sources used in problem solving: the use of U.S. government technical reports in problem solving and the information sources used to find out about U.S. government technical reports.

This project is designed to explore the diffusion of scientific and technical information (STI) throughout the aerospace industry. The increased international competition and cooperation in the industry promises to significantly affect the STI standards of U.S. aerospace engineers and scientists. Therefore, it is important to understand the aerospace knowledge diffusion process itself and its implications at the individual, organizational, national, and international levels. Examined here is the role of STI in the academic aerospace community.

The objectives of this study were to examine (1) whether the onset of sexually transmitted infections (STI) through age 30 differed for youths who received a social developmental intervention during elementary grades compared to those in the control condition; (2) potential social-developmental mediators of this intervention; and (3) the extent to which these results differed by ethnicity. A nonrandomized controlled trial followed participants to age 30, 18 years after the intervention ended. Three intervention conditions were compared: a full-intervention group, assigned to intervention in grades 1 through 6; a late intervention group, assigned to intervention in grades 5 and 6 only; and a no-treatment control group. Eighteen public elementary schools serving diverse neighborhoods including high-crime neighborhoods of Seattle are the setting of the study. Six hundred eight participants in three intervention conditions were interviewed from age 10 through 30. Interventions include teacher training in classroom instruction and management, child social and emotional skill development, and parent workshops. Outcome is the cumulative onset of participant report of STI diagnosis. Adolescent family environment, bonding to school, antisocial peer affiliation, early sex initiation, alcohol use, cigarette use, and marijuana use were tested as potential intervention mechanisms. Complementary log-log survival analysis found significantly lower odds of STI onset for the full-intervention compared to the control condition. The lowering of STI onset risk was significantly greater for African Americans and Asian Americans compared to European Americans. Family environment, school bonding, and delayed initiation of sexual behavior mediated the relationship between treatment and STI hazard. A universal intervention for urban elementary school children, focused on classroom management and instruction, children's social competence, and parenting practices may reduce the onset of STI

The development status of optical processing techniques under development at NASA-JPL, NASA-Ames, and NASA-Johnson, is evaluated with a view to their potential applications in future NASA planetary exploration missions. It is projected that such optical processing systems can yield major reductions in mass, volume, and power requirements relative to exclusively electronic systems of comparable processing capabilities. Attention is given to high-order neural networks for distortion-invariant classification and pattern recognition, multispectral imaging using an acoustooptic tunable filter, and an optical matrix processor for control problems.

Female Sex Worker Social Networks and STI/HIV Prevention in South China

2011-01-01

Background Reducing harm associated with selling and purchasing sex is an important public health priority in China, yet there are few examples of sustainable, successful programs to promote sexual health among female sex workers. The limited civil society and scope of nongovernmental organizations circumscribe the local capacity of female sex workers to collectively organize, advocate for their rights, and implement STI/HIV prevention programs. The purpose of this study was to examine social networks among low-income female sex workers in South China to determine their potential for sexual health promotion. Methods/Principal Findings Semi-structured interviews with 34 low-income female sex workers and 28 health outreach members were used to examine how social relationships affected condom use and negotiation, STI/HIV testing and health-seeking behaviors, and dealing with violent clients. These data suggested that sex worker's laoxiang (hometown social connections) were more powerful than relationships between women selling sex at the same venue in establishing the terms and risk of commercial sex. Female sex workers from the same hometown often migrated to the city with their laoxiang and these social connections fulfilled many of the functions of nongovernmental organizations, including collective mobilization, condom promotion, violence mitigation, and promotion of health-seeking behaviors. Outreach members observed that sex workers accompanied by their laoxiang were often more willing to accept STI/HIV testing and trust local sexual health services. Conclusions/Significance Organizing STI/HIV prevention services around an explicitly defined laoxiang social network may provide a strong foundation for sex worker health programs. Further research on dyadic interpersonal relationships between female sex workers, group dynamics and norm establishment, and the social network characteristics are needed. PMID:21931856

2000-01-01

Objective: To evaluate the effectiveness of a pilot peer education STI prevention programme with male sex workers. Design: A process and outcome evaluation of the pilot programme undertaken in three London male escort agencies, using a quasi-experimental design. Subjects: Workers in three London escort agencies, including 88 who completed a questionnaire, five peer educators, and a further 16 men (including management) working in two of these agencies. Methods: A peer education STI prevention programme run by the Working Men Project (WMP), a specialist sexual health service for male sex workers, was piloted in two London escort agencies. Five male sex workers participated in a 2 day peer education training programme. They then returned to their respective agencies to disseminate information and condoms, in an attempt to influence norms of behaviour. An outcome evaluation aimed to assess changes in STI related knowledge, high risk sexual behaviour, and attendance at a sexual health service. A pre-intervention questionnaire assessing variables such as STI related knowledge, sexual behaviour, and demographic information was administered in both agency A and agency B and a third agency, C, which acted as a control. Ten weeks after the peer educators returned to their agencies, the same questionnaire was administered in the same agencies. Peer educator referrals to the WMP were also recorded over this time period. The process evaluation involved interviews and focus groups with peer educators, and the completion of diaries about their experiences in the role. A further 16 men working in the agencies (including managers and an owner) were interviewed about their experience of the programme. Participant observation was also undertaken through regular outreach work to the agencies. Results: 57 men completed the questionnaire at time 1 and 44 at time 2. Unfortunately, only 13 of these were matched, precluding any meaningful analysis of change in STI related knowledge and

Patients with pharyngitis often describe various sensory, affective and evaluative pain qualities. Using an 11-word/phrase index, the Qualities of Sore Throat Index (QuaSTI), we characterized throat symptoms and evaluated changes in a randomized controlled trial (NCT01986361). Patients received a single flurbiprofen 8.75 mg (n = 101) or placebo (n = 21) lozenge and rated throat soreness at baseline and regular intervals over 3 h, and the QuaSTI at baseline, 1, 2 and 3 h post-treatment. The QuaSTI distinguished active drug from placebo and detected clinically important (≥2-point) changes over 3 h. Mean change from baseline over 3 h was significantly greater for flurbiprofen (154%) than placebo (p < 0.05). The QuaSTI is a sensitive instrument for measuring therapeutic effects in patients with pharyngitis.

Weather is a contributing factor in approximately 25-30 percent of general aviation accidents. The lack of timely, accurate and usable weather information to the general aviation pilot in the cockpit to enhance pilot situational awareness and improve pilot judgment remains a major impediment to improving aviation safety. NASA Glenn Research Center commissioned this 120 day weather datalink market survey to assess the technologies, infrastructure, products, and services of commercial avionics systems being marketed to the general aviation community to address these longstanding safety concerns. A market survey of companies providing or proposing to provide graphical weather information to the general aviation cockpit was conducted. Fifteen commercial companies were surveyed. These systems are characterized and evaluated in this report by availability, end-user pricing/cost, system constraints/limits and technical specifications. An analysis of market survey results and an evaluation of product offerings were made. In addition, recommendations to NASA for additional research and technology development investment have been made as a result of this survey to accelerate deployment of cockpit weather information systems for enhancing aviation safety.

Currently, surveillance of sexually transmitted infections (STIs) among ethnic minorities (EM) in the Netherlands is mainly performed using data from STI centers, while the general practitioner (GP) is the most important STI care provider. We determined the frequency of STI-related episodes at the general practice among EM, and compared this with the native Dutch population. Electronic medical records from 15-to 60-year-old patients registered in a general practice network from 2002 to 2011 were linked to the population registry, to obtain (parental) country of birth. Using diagnoses and prescription codes, we investigated the number of STI-related episodes per 100,000 patient years by ethnicity. Logistic regression analyses (crude and adjusted for gender, age, and degree of urbanization) were performed for 2011 to investigate differences between EM and native Dutch. The reporting rate of STI-related episodes increased from 2004 to 2011 among all ethnic groups, and was higher among EM than among native Dutch, except for Turkish EM. After adjustment for gender, age, and degree of urbanization, the reporting rate in 2011 was higher among Surinamese [Odds Ratio (OR) 1.99, 95 % confidence interval (CI) 1.70-2.33], Antillean/Aruban (OR 2.48, 95 % CI 2.04-3.01), and Western EM (OR 1.24, 95 % CI 1.11-1.39) compared with native Dutch, whereas it was lower among Turkish EM (OR 0.48, 95 % CI 0.37-0.61). Women consulted the GP relatively more frequently regarding STIs than men, except for Turkish and Moroccan women. Most EM consult their GP more often for STI care than native Dutch. However, it remains unclear whether this covers the need of EM groups at higher STI risk. As a first point of contact for care, GPs can play an important role in reaching EM for (proactive) STI/HIV testing.

The organization of STI/HIV risk-taking among long-line fishermen in Bali, Indonesia.

Setiawan, I Made; Patten, Jane H

2010-01-01

We report on selected findings of a qualitative social network study investigating STI/HIV-related risk among migrant fishermen based at one of Indonesia's major fishing ports in Bali. Their activities between fishing trips include drinking parties, watching pornographic videos, and visiting brothels, while condom use is rare. While on board, they plan and anticipate these activities and many insert penile implants. These fishermen run a high personal risk of contracting STI/HIV, and, with their circular migration patterns among Indonesian and foreign ports such as Thailand and South Africa, and with visits back to their rural hometowns and wives or girlfriends in Java, there is a serious risk of disease transmission to the general population. This paper argues that the role that social interactions play in HIV/AIDS-related risks should be considered as important as (if not more important than) individual knowledge, attitudes, and practices in the design of effective STI/HIV prevention programs.

The glycolytic metabolite methylglyoxal activates Pap1 and Sty1 stress responses in Schizosaccharomyces pombe.

Methylglyoxal, a toxic metabolite synthesized in vivo during glycolysis, inhibits cell growth. One of the mechanisms protecting eukaryotic cells against its toxicity is the glyoxalase system, composed of glyoxalase I and II (glo1 and glo2), which converts methylglyoxal into d-lactic acid in the presence of glutathione. Here we have shown that the two principal oxidative stress response pathways of Schizosaccharomyces pombe, Sty1 and Pap1, are involved in the response to methylglyoxal toxicity. The mitogen-activated protein kinase Sty1 is phosphorylated and accumulates in the nucleus following methylglyoxal treatment. Moreover, glo2 expression is induced by methylglyoxal and environmental stresses in a Sty1-dependent manner. The transcription factor Pap1 also accumulates in the nucleus, activating the expression of its target genes following methylglyoxal treatment. Our studies showed that the C-terminal cysteine-rich domain of Pap1 is sufficient for methylglyoxal sensing. Furthermore, the redox status of Pap1 is not changed by methylglyoxal. We propose that methylglyoxal treatment triggers Pap1 and Sty1 nuclear accumulation, and we describe the molecular basis of such activation mechanisms. In addition, we discuss the potential physiological significance of these responses to a natural toxic metabolite.

yourSkyG is the second generation of the software described in yourSky: Custom Sky-Image Mosaics via the Internet (NPO-30556), NASA Tech Briefs, Vol. 27, No. 6 (June 2003), page 45. Like its predecessor, yourSkyG supplies custom astronomical image mosaics of sky regions specified by requesters using client computers connected to the Internet. Whereas yourSky constructs mosaics on a local multiprocessor system, yourSkyG performs the computations on NASA s Information Power Grid (IPG), which is capable of performing much larger mosaicking tasks. (The IPG is high-performance computation and data grid that integrates geographically distributed 18 NASA Tech Briefs, September 2005 computers, databases, and instruments.) A user of yourSkyG can specify parameters describing a mosaic to be constructed. yourSkyG then constructs the mosaic on the IPG and makes it available for downloading by the user. The complexities of determining which input images are required to construct a mosaic, retrieving the required input images from remote sky-survey archives, uploading the images to the computers on the IPG, performing the computations remotely on the Grid, and downloading the resulting mosaic from the Grid are all transparent to the user

Employment and contextual impact of safe and unsafe sexual practices for STI and HIV: the situation in China.

China's dual employment system plays a crucial role in sexually transmitted infections (STIs) and HIV-related safe and unsafe sexual practices among young Chinese people. Social and psychological determinants of safe and unsafe sexual practices for HIV infection among young people in Sichuan, China were examined. Our findings indicate that changes in China's social structure and employment system impact upon the social contextual involvement and socio-sexual practice of young Chinese people. The findings in the study suggest that the employment-related contextual involvement was a major predictor in the relationships between demography, information, and psychological risk-taking factors on one hand and the people's safe and unsafe sexual practices on the other. Self-employed people (officially called 'getihu') were more likely than the state-employed people to engage in unprotected sex with casual sexual partners. As China undergoes social restructuring and many state-employed people are laid off, the risk may also extend into the broader non-self-employed population as more state-employed people become involved not only in the self-employed getihu's socioeconomic activities but also in their unconventional socio-sexual practices. Collective vulnerability to STI and HIV, due to the current socio-sexual practices of the getihu young people, has created a new frontier for STI and HIV prevention in today's China, as well as demonstrating the importance of collective action with STI and AIDS prevention strategies within relevant social and sub-cultural contexts.

Evolution of Scientific and Technical Information Distribution

NASA Technical Reports Server (NTRS)

Esler, Sandra; Nelson, Michael L.

1998-01-01

World Wide Web (WWW) and related information technologies are transforming the distribution of scientific and technical information (STI). We examine 11 recent, functioning digital libraries focusing on the distribution of STI publications, including journal articles, conference papers, and technical reports. We introduce 4 main categories of digital library projects: based on the architecture (distributed vs. centralized) and the contributor (traditional publisher vs. authoring individual/organization). Many digital library prototypes merely automate existing publishing practices or focus solely on the digitization of the publishing cycle output, not sampling and capturing elements of the input. Still others do not consider for distribution the large body of "gray literature." We address these deficiencies in the current model of STI exchange by suggesting methods for expanding the scope and target of digital libraries by focusing on a greater source of technical publications and using "buckets," an object-oriented construct for grouping logically related information objects, to include holdings other than technical publications.

Rising rates of sexually transmitted infections (STIs) warrant a renewed focus on the management of STIs in health care organizations. The extent to which hospitals and community health centers (CHCs) have established processes and allocated staff for the management of STIs within their organizations remains poorly understood. A New York State Department of Health survey was distributed electronically through a closed state communication network to targeted administrators at New York State hospitals and CHCs. The survey asked if STI management in their facilities included the following: the ability to measure and report rates of STIs, a process to assess the quality of STI care and treatment outcomes, and a centralized person/unit to coordinate its work throughout the facility. Multivariate analysis was performed to identify whether organizational characteristics were associated with survey findings. Ninety-five percent (243/256) of hospitals and CHCs responded to the survey. Fifty percent of respondents had a person or unit to report rates of STIs; 30% reported an organization-wide process for monitoring the quality of STI care, which, according to the multivariate analysis, was associated with CHCs; only 23% reported having a centralized person or unit for coordinating STI management. Most facilities report STI cases to comply with public health surveillance requirements but do not measure infection rates, assess the quality of STI care, or coordinate its work throughout the facility. The development of this organizational capacity would likely decrease STI rates, improve treatment outcomes, and address local public health goals.

Genomes of ten species of Elymus, either presumed or known as tetraploid StY, were characterized using fluorescence in situ hybridization (FISH) and genomic in situ hybridization (GISH). These tetraploid species could be grouped into three categories. Type I included StY genome reported species-Roegneria pendulina, R. nutans, R. glaberrima, R. ciliaris, and Elymus nevskii, and StY genome presumed species-R. sinica, R. breviglumis, and R. dura, whose genome could be separated into two sets based on different GISH intensities. Type I genome constitution was deemed as putative StY. The St genome were mainly characterized with intense hybridization with pAs1, fewer AAG sites, and linked distribution of 5S rDNA and 18S-26S rDNA, while the Y genome with less intense hybridization with pAs1, more varied AAG sites, and isolated distribution of 5S rDNA and 18S-26S rDNA. Nevertheless, further genomic variations were detected among the different StY species. Type II included E. alashanicus, whose genome could be easily separated based on GISH pattern. FISH and GISH patterns suggested that E. alashanicus comprised a modified St genome and an unknown genome. Type III included E. longearistatus, whose genome could not be separated by GISH and was designated as St l Y l . Notably, a close relationship between S l and Y l genomes was observed.

2015-06-01

The socioeconomic status (SES) of women is increasingly considered an important factor for HIV/STI risk. The HIV/STI literature has largely focused on women's absolute levels of SES, and therefore, the importance of their SES relative to their male sexual partners remains understudied. This paper examines the association between women's relative SES and frequency of safer sex communication among heterosexual couples. A convenience sample of 342 couples (N = 684) recruited in New York City was asked about frequency of discussions with their partner about the need to use male condoms, about HIV prevention, and about STI prevention in the previous 90 days. Differences between partners in education, income, employment, housing, and incarceration history were combined using principal component analysis to form an index of women's relative SES. Negative binomial regression models assessed associations between woman's relative SES and communication frequency controlling for age, sex, race, ethnicity, education, and relationship type using a generalized estimating equation framework. On average, participants had 2.5, 4.2, and 4.8 discussions regarding the need to use male condoms, about HIV prevention, and about STI prevention, respectively. A one standard deviation increase in a woman's relative SES score was associated with increased frequency of discussions about male condom use (adjusted rate ratio [aRR], 1.15; 95% confidence interval [CI], 1.03-1.29), about HIV prevention (aRR, 1.25; CI, 1.14-1.37), and about STI prevention (aRR, 1.29; CI, 1.18-1.41). Women's relative SES may be an important factor for sexual communication, and further research on its role in HIV/STI risk may uncover avenues for intervention.

Background Research on the association between antisocial personality disorder (ASPD) with comorbid mental disorders and sexually transmitted infection (STI)/HIV risk among inmates is scant despite the high prevalence of psychopathology and of STI/HIV in this population. Methods We used baseline data from Project DISRUPT, a cohort study conducted among incarcerated African American men (n= 207), to measure associations between ASPD and STI/HIV risk. We also conducted latent class analyses (LCAs) to identify subgroups defined by ASPD with comorbid stress, depression, and borderline personality disorder symptoms and measured associations between latent class membership and STI/HIV risk. Results Approximately 15% had ASPD and 39% reported depression. Controlling for sociodemographics, stress, and depression, ASPD was independently associated with illicit [AOR=3.23, 95% confidence interval (CI): 1.18–8.87] and injection drug use (AOR: 5.49, 95% CI: 1.23–24.42) but not with sexual risk. LCAs suggested that those at high risk of ASPD were likely to experience co-morbid mental disorders. ASPD comorbid with these disorders was linked to drug and sex risk. Conclusions STI/HIV prevention for inmates should incorporate diagnosis and treatment of ASPD and comorbid disorders, and interventions to address ASPD-related factors (e.g., impulsivity) that drive STI/HIV risk.

STI: An objective measure for the performance of voice communication systems

NASA Astrophysics Data System (ADS)

Houtgast, T.; Steeneken, H. J. M.

1981-06-01

A measuring device was developed for determining the quality of speech communication systems. It comprises two parts, a signal source which replaces the talker, producing an artificial speech-like signal, and an analysis part which replaces the listener, by which the signal at the receiving end of the system under test is evaluated. Each single measurement results in an index (ranging from 0-100%) which indicates the effect of that communication system on speech intelligibility. The index is called STI (Speech Transmission Index). A careful design of the characteristics of the test signal and of the type of signal analysis makes the present approach widely applicable. It was verified experimentally that a given STI implies a given effect on speech intelligibility, irrespective of the nature of the actual disturbance (noise interference, band-pass limiting, peak clipping, etc.).

We examined the long-term effects of two interventions designed to reduce sexual risk behavior among African American adolescents. African American adolescents (N = 1383, ages 14-17) were recruited from community-based organizations over a period of 16 months in two northeastern and two southeastern mid-sized U.S. cities with high rates of sexually transmitted infection (STI). Participants were screened for three STIs (gonorrhea, chlamydia, and trichomoniasis) and completed an audio computer-assisted attitude, intention, and behavior self-interview. Youth who tested positive for an STI (8.3%) received treatment and risk reduction counseling. In addition, television and radio HIV-prevention messages were delivered during the recruitment period and 18 months of follow-up in one randomly selected city in each region. Analyses determined effects of the media program for those receiving a positive versus negative STI test result on number of sexual partners and occurrence of unprotected sex. Adolescents who tested STI-positive reduced their number of vaginal sex partners and the probability of unprotected sex over the first 6 months. However, in the absence of the mass media program, adolescents returned to their previously high levels of sexual risk behavior after 6 months. Adolescents who tested STI-positive and received the mass media program showed more stable reductions in unprotected sex. Community-based STI treatment and counseling can achieve significant, but short-lived reductions in sexual risk behavior among STI-positive youth. A culturally sensitive mass media program has the potential to achieve more stable reductions in sexual risk behavior and can help to optimize the effects of community-based STI screening.

Purpose To test the fit of a theoretically driven conceptual model of pathways to STI risk among foster youth transitioning to adulthood. The model included: 1) historical abuse and foster care experiences, 2) mental health and attachment style in late adolescence, and 3) STI risk in young adulthood. Methods We used path analysis to analyze data from a longitudinal study of 732 youth transitioning out of foster care. Covariates included gender, race and an inverse probability weight. We also performed moderation analyses comparing models constrained and unconstrained by gender. Results Thirty percent reported they or a partner had been diagnosed with an STI. Probability of other measured STI risk behaviors ranged from 9% (having sex for money) to 79% (inconsistent condom use). Overall model fit was good (Standardized Root Mean Squared Residual of 0.026). Increased risk of oppositional/delinquent behaviors mediated an association between abuse history and STI risk, via increased inconsistent condom use. There was also a borderline association with having greater than 5 partners. Having a very close relationship with a caregiver and remaining in foster care beyond age 18 decreased STI risk. Moderation analysis revealed better model fit when coefficients were allowed to vary by gender versus a constrained model, but few significant differences in individual path coefficients were found between male and female-only models. Conclusions Interventions/policies that: 1) address externalizing trauma sequelae, 2) promote close, stable substitute caregiver relationships, and 3) extend care to age 21 years have the potential to decrease STI risk in this population.

Perceived devaluation has been shown to have adverse effects on the mental and physical health outcomes of people who use drugs. However, the impact of perceived devaluation on sexually transmitted infections (STI) testing uptake among street-involved youth, who face multiple and intersecting stigmas due to their association with drug use and risky sexual practices, has not been fully characterized. Data were obtained between December 2013 and November 2014 from a cohort of street-involved youth who use illicit drugs aged 14-26 in Vancouver, British Columbia. Multivariable generalized estimating equations were constructed to assess the independent relationship between perceived devaluation and STI testing uptake. Among 300 street-involved youth, 87.0% reported a high perceived devaluation score at baseline. In the multivariable analysis, high perceived devaluation was negatively associated with STI testing uptake after adjustment for potential confounders (Adjusted Odds Ratio = 0.38, 95% Confidence Interval 0.15-0.98). Perceived devaluation was high among street-involved youth in our sample and appears to have adverse effects on STI testing uptake. HIV prevention and care programs should be examined and improved to better meet the special needs of street-involved youth in non-stigmatizing ways.

A telephone survey of U.S. aerospace engineers and scientists who were on the Society of Automotive Engineers (SAE) mailing list was conducted between August 14-26, 1991. The survey was undertaken to obtain information on the daily work activities of aerospace engineers and scientists, to measure various practices used by aerospace engineers and scientists to obtain STI, and to ask aerospace engineers and scientists about their use of electronic networks. Co-workers were found important sources of information. Co-workers are used to obtain technical information because the information they have is relevant, not because co-workers are accessible. As technical uncertainty increases, so does the need for information internal and external to the organization. Electronic networks enjoy widespread use within the aerospace community. These networks are accessible and they are used to contact people at remote sites. About 80 percent of the respondents used electronic mail, file transfer, and information or data retrieval to commercial or in-house data bases.

The World Health Organization Sexually Transmitted Diseases Diagnostics Initiative (SDI) website publication review seeks to provide health care providers in all geographic and economic settings with timely, critical, and concise information concerning new developments in laboratory and field diagnosis of sexually transmitted infections (STI). Since 2003, the website (www.who.int/std_diagnostics/literature_reviews) has disseminated information in the form of annotated abstracts and commentaries on articles covering studies of STI laboratory-based and rapid assays that are commercially available or under development. Articles identified through searches of PubMed, specific journals, and by referrals from Editorial Board members are selected for inclusion if they meet pre-specified criteria. The objectives, methods, results, and conclusions for each article are summarised and board members are invited to prepare commentaries addressing study design and applicability of findings to end users. Currently, 91 STI diagnostics experts from 17 countries on six continents serve on the Editorial Board. Twelve quarterly issues have been posted that include summaries of 214 original and 17 review articles published from January 2002 through March 2005, with expert commentaries on 153 articles. Interest in the site has increased every year. In 2005, over 36 700 unique visitors from more than 100 countries viewed over 75,000 pages of information. The SDI Publication Review series has the potential to contribute to SDI's goal of improving care for patients with STI by increasing knowledge and awareness of STI diagnostics. Given the proliferation of internet-based STI testing services, this website may be broadened to meet the needs of a wider range of users.

Strategies for Information Retrieval and Virtual Teaming to Mitigate Risk on NASA's Missions

Topousis, Daria; Williams, Gregory; Murphy, Keri

2007-01-01

Following the loss of NASA's Space Shuttle Columbia in 2003, it was determined that problems in the agency's organization created an environment that led to the accident. One component of the proposed solution resulted in the formation of the NASA Engineering Network (NEN), a suite of information retrieval and knowledge sharing tools. This paper describes the implementation of this set of search, portal, content management, and semantic technologies, including a unique meta search capability for data from distributed engineering resources. NEN's communities of practice are formed along engineering disciplines where users leverage their knowledge and best practices to collaborate and take informal learning back to their personal jobs and embed it into the procedures of the agency. These results offer insight into using traditional engineering disciplines for virtual teaming and problem solving.

Objectives. We assessed the effectiveness of 2 environmental–structural interventions in reducing risks of HIV and sexually transmitted infections (STIs) among female sex workers in the Dominican Republic. Methods. Two intervention models were implemented over a 1-year period: community solidarity in Santo Domingo and solidarity combined with government policy in Puerto Plata. Both were evaluated via preintervention–postintervention cross-sectional behavioral surveys, STI testing and participant observations, and serial cross-sectional STI screenings. Results. Significant increases in condom use with new clients (75.3%–93.8%; odds ratio [OR]=4.21; 95% confidence interval [CI]=1.55, 11.43) were documented in Santo Domingo. In Puerto Plata, significant increases in condom use with regular partners (13.0%–28.8%; OR=2.97; 95% CI=1.33, 6.66) and reductions in STI prevalence (28.8%–16.3%; OR = 0.50; 95% CI = 0.32, 0.78) were documented, as were significant increases in sex workers’ verbal rejections of unsafe sex (50.0%–79.4%; OR=3.86; 95% CI=1.96, 7.58) and participating sex establishments’ ability to achieve the goal of no STIs in routine monthly screenings of sex workers (OR=1.17; 95% CI=1.12, 1.22). Conclusions. Interventions that combine community solidarity and government policy show positive initial effects on HIV and STI risk reduction among female sex workers. PMID:16317215

Young people often express a preference for seeking family planning information and services from the private sector. However, in many Marie Stopes International (MSI) social franchise networks, the proportion of young clients, and particularly those under 20 years of age, remains low. Marie Stopes Madagascar (MSM) piloted a youth voucher program that joins a supply-side intervention-youth-friendly social franchisee training and quality monitoring-with a corresponding demand-side-component, free vouchers that reduce financial barriers to family planning access for young people. Young people identified by MSM's community health educators (CHEs) received a free voucher redeemable at a BlueStar social franchisee for a package of voluntary family planning and sexually transmitted infection (STI) information and services. BlueStar social franchisees-private providers accredited by MSM-are reimbursed for the cost of providing these services. We reviewed service statistics data from the first 18 months of the youth voucher program, from July 2013 to December 2014, as well as client demographic profile data from July 2015. Findings: Between July 2013 and December 2014, 58,417 vouchers were distributed to young people by CHEs through a range of community mobilization efforts, of which 43,352 (74%) were redeemed for family planning and STI services. Most clients (78.5%) chose a long-acting reversible contraceptive (LARC), and just over half (51%) of young people benefited from STI counseling as part of their voucher service. Most (78%) services were provided in the Analamanga region (the capital and its surroundings), which was expected given the population density in this region and the high concentration of BlueStar franchisees. The client profile data snapshot from July 2015 revealed that 69% of voucher clients had never previously used a contraceptive method, and 96% of clients were aged 20 or younger, suggesting that the voucher program is successfully reaching the

The NASA End-to-End Data System (NEEDS) program was initiated by NASA to improve significantly the state of the art in acquisition, processing, and distribution of space-acquired data for the mid-1980s and beyond. The information adaptive system (IAS) is a program element under NEEDS Phase II which addresses sensor specific processing on board the spacecraft. The IAS program is a logical first step toward smart sensors, and IAS developments - particularly the system components and key technology improvements - are applicable to future smart efforts. The paper describes the design goals and functional elements of the IAS. In addition, the schedule for IAS development and demonstration is discussed.

The objectives of this study were to: (1) describe the quantity and quality of social support networks of Latino immigrants living in a new receiving environment, and (2) determine the role such networks play in their HIV/STI risk behaviors, including substance use. Double incentivized convenience sampling was used to collect egocentric social support network data on 144 Latino immigrants. Latent class analysis was used for data reduction and to identify items best suited to measure quality and quantity of social support. Moderate and high quantity and quality of social support were protective of HIV/STI sexual risk behavior compared to low quantity and quality of support, after adjustment for gender, years in New Orleans and residing with family. Neither measure of social support was associated with binge drinking. The findings suggest that increased quantity and quality of social support decrease HIV/STI sexual risk behaviors but do not influence binge drinking. Interventions that improve the quantity and quality of social support are needed for Latino immigrants.

Evolving health priorities and resource constraints mean that countries require data on trends in sexually transmitted infections (STI) burden, to inform program planning and resource allocation. We applied the Spectrum STI estimation tool to estimate the prevalence and incidence of active syphilis in adult women in Morocco over 1995 to 2016. The results from the analysis are being used to inform Morocco's national HIV/STI strategy, target setting and program evaluation. Syphilis prevalence levels and trends were fitted through logistic regression to data from surveys in antenatal clinics, women attending family planning clinics and other general adult populations, as available post-1995. Prevalence data were adjusted for diagnostic test performance, and for the contribution of higher-risk populations not sampled in surveys. Incidence was inferred from prevalence by adjusting for the average duration of infection with active syphilis. In 2016, active syphilis prevalence was estimated to be 0.56% in women 15 to 49 years of age (95% confidence interval, CI: 0.3%-1.0%), and around 21,675 (10,612-37,198) new syphilis infections have occurred. The analysis shows a steady decline in prevalence from 1995, when the prevalence was estimated to be 1.8% (1.0-3.5%). The decline was consistent with decreasing prevalences observed in TB patients, fishermen and prisoners followed over 2000-2012 through sentinel surveillance, and with a decline since 2003 in national HIV incidence estimated earlier through independent modelling. Periodic population-based surveys allowed Morocco to estimate syphilis prevalence and incidence trends. This first-ever undertaking engaged and focused national stakeholders, and confirmed the still considerable syphilis burden. The latest survey was done in 2012 and so the trends are relatively uncertain after 2012. From 2017 Morocco plans to implement a system to record data from routine antenatal programmatic screening, which should help update and re

Although studies have consistently demonstrated that women at high risk for HIV and non-HIV sexually transmitted infections (STIs) tend to underestimate their individual risk, little is known about how women at risk perceive their community's HIV/STI risk. We explored perceptions of community HIV/STI risk among U.S. women living in areas with high poverty and HIV prevalence rates as part of a qualitative substudy of the Women's HIV SeroIncidence Study. Semi-structured focus groups were conducted. Data were coded and analyzed using the constant comparative method. Participants expressed the perception that their communities were at elevated HIV/STI risk, mostly due to contextual and structural factors such as lack of access to health care and education. Findings suggest that HIV prevention messages that target U.S. women at high risk for HIV may be strengthened by addressing the high perceived community HIV/STI risk driven by structural factors.

The current study examined the feasibility of an HIV/STI prevention intervention for African American female adolescents. The intervention SiHLEWeb is a web-based adaptation of the evidence-based intervention, Sistas, Informing, Healing, Living, and Empowering (SiHLE). Participants were 41 African American girls aged 13 to 18 years, recruited in collaboration with community partners (local high schools, Department of Juvenile Justice, child advocacy center, medical university). Results support the feasibility of recruitment, screening, and follow-up retention methods. The majority (63.4%) of recruited participants completed the intervention, taking an average of 4.5 (SD = 3.63) site visits. Completers of SiHLEWeb demonstrated increases in knowledge regarding HIV/STI risks and risk reduction behavior [t(18) = 4.74, p < .001], as well as significant increases in condom use self-efficacy [t(16) = 2.41, p = .03]. Findings provide preliminary support for the large-scale, randomized-controlled trial of the efficacy of SiHLEWeb to reduce high-risk sexual behavior among female African American adolescents.

Studies have indicated that land cover and use changes in Northern Eurasia influence global climate system. However, the procedures are not fully understood and it is challenging to understand the interactions between the land changes in this region and the global climate. Having integrated data collections form multiple disciplines are important for studies of climate and environmental changes. Remote sensed and model data are particularly important die to sparse in situ measurements in many Eurasia regions especially in Siberia. The NASA GES DISC (Goddard Earth Sciences Data and Information Services Center) NEESPI data portal has generated infrastructure to provide satellite remote sensing and numerical model data for atmospheric, land surface, and cryosphere. Data searching, subsetting, and downloading functions are available. ONe useful tool is the Web-based online data analysis and visualization system, Giovanni (Goddard Interactive Online Visualization ANd aNalysis Infrastructure), which allows scientists to assess easily the state and dynamics of terrestrial ecosystems in Northern Eurasia and their interactions with global climate system. Recently, we have created a metadata database prototype to expand the NASA NEESPI data portal for providing a venue for NEESPI scientists fo find the desired data easily and leveraging data sharing within NEESPI projects. The database provides product level information. The desired data can be found through navigation and free text search and narrowed down by filtering with a number of constraints. In addition, we have developed a Web Map Service (WMS) prototype to allow access data and images from difference data resources.

Cultural adaptation is an important step in the process of implementing health promotion interventions that, having been proven to be effective in one culture, are being applied in another. This study describes the results of a formative investigation to culturally adapt a STI/HIV risk reduction intervention for use in St. Petersburg, Russia. Analyses of data from brief elicitation interviews, focus groups, community experts, and a pilot test of the adapted intervention identified environmental, cognitive-information processing, and affect-motivation factors that needed to be addressed during the adaptation process. The participant/counselor relationship was adapted to reflect a hierarchical (cf. collaborative) relationship in order to accommodate Russian expectations about patient interactions with healthcare experts. Key skills building activities (e.g., identification of personal risk behaviors, role-playing) were approached gradually or indirectly in order to maintain participants' engagement in the intervention, and close-ended questions were added to assist participants in understanding unfamiliar concepts such as "triggers" and self-efficacy. Information about the prevalence of HIV/STI infections and alcohol use included data specific to St. Petersburg to increase the personal relevance of these materials and messages. Intervention components were tailored to participants' risk reduction and informational needs. No gender differences that would have justified adaptation of the intervention approach or content were noted. Examples of specific adaptations and the key issues to attend to when adapting behavioral interventions for use in Russian clinical settings are discussed.

Male sex workers (MSW) are particularly exposed to sexually transmitted infections (STI) including HIV. In the Netherlands, data about STI among MSW are scarce. We estimated chlamydia, gonorrhoea, syphilis and HIV diagnoses among MSW attending STI clinics and determined associated factors to guide prevention policies. Using 2006-2012 cross-sectional national surveillance data from Dutch STI clinics, we calculated the proportion of consultations with a positive test for any of three bacterial STI or HIV among MSW. Associated factors were determined by using Poisson logistic regression with robust variance. We identified 3,053 consultations involving MSW, of which 18.1 % included at least one positive bacterial STI test and 2.5 % a positive HIV test. Factors associated with bacterial STI and/or HIV diagnoses were respectively age groups < 35 y.o. and self-reporting homo- or bisexual preferences (aRR = 1.6; 95 % CI: 1.3-2.1), and age group 25-34 y.o. (aRR = 2.7; 95 % CI: 1.2-6.5) and self-reporting homo- or bisexual preferences (aRR = 24.4; 95 % CI: 3.4-176.9). Newly diagnosed and pre-existing HIV infection were associated with an increased risk for bacterial STI (aRR = 2.7, 95 % CI: 1.7-2.6 and aRR = 2.1, 95 % CI: 2.2-3.4 respectively). MSW with no history of HIV screening were more likely to be tested positive for HIV compared to those with a previous HIV-negative test (aRR = 2.6, 95 % CI: 1.6-4.3). Health promotion activities should target MSW who are young, homo- or bisexual, those who are HIV-infected or who have never been tested for HIV, to increase early diagnosis, prevention and treatment.

To explore knowledge, attitudes and sexual practices of male sex workers (MSW) in Tel Aviv in comparison with men who have sex with men (MSM) classified by their risk behaviours and to outline attributes related to sexually transmitted infections (STI)/HIV prevalence. MSW were recruited for this cross-sectional study from designated street venues and gay-dating internet site. MSM were recruited from gay-related venues and divided into high-risk MSM (HRMSM) if they performed unprotected anal intercourse in the last 6 months with an HIV-discordant/unknown partner and to low-risk MSM (LRMSM). Each participant completed a questionnaire and was tested for STI/HIV. Of 87 MSW and 635 MSM approached, 53 (60.9%) and 235 (37.0%) participated, respectively. Street-MSW (N=32) had more female sex partners and were more drug dependent than internet-MSW (N=21). No differences were found in their knowledge regarding STI/HIV transmission, practices and STI/HIV burden. Compared with HRMSM, MSW had different demographic attributes and demonstrated more realistic perception regarding the risk to getting STI/HIV, while no differences were found in their knowledge and sexual practices. STI burden among MSW, HRMSM (N=119) and LRMSM (N=116) were 28.3%, 23.5% and 10.3% (p=0.009) and HIV burden among MSW, HRMSM and LRMSM were 5.6%, 9.2% and 0%, (p=0.001), respectively. Multivariate models evaluating attributes associated with HIV/STI diagnosis did not find sex work to be significant if the variable used was MSW versus HRMSM, regardless of the adjustments performed. However, when MSW versus LRMSM was used in the model, sex work was associated with STI/HIV diagnosis. Street-MSW and internet-MSW, similar to all MSW and HRMSM, had comparable sexual practices and had no difference in their STI/HIV prevalence.

Mixed-method designs are increasingly used in sexually transmitted infection (STI) and HIV prevention research. The authors designed a mixedmethod approach and applied it to estimate and evaluate a predictor of continued female condom use (6+ uses, among those who used it at least once) in a 6-month prospective cohort study. The analysis included 402 women who received an intervention promoting use of female and male condoms for STI prevention and completed monthly quantitative surveys; 33 also completed a semistructured qualitative interview. The authors identified a qualitative theme (couples' female condom enjoyment [CFCE]), applied discriminant analysis techniques to estimate CFCE for all participants, and added CFCE to a multivariable logistic regression model of continued female condom use. CFCE related to comfort, naturalness, pleasure, feeling protected, playfulness, ease of use, intimacy, and feeling in control of protection. CFCE was associated with continued female condom use (adjusted odds ratio: 2.8, 95% confidence interval: 1.4-5.6) and significantly improved model fit (p < .001). CFCE predicted continued female condom use. Mixed-method approaches for "scaling up" qualitative findings from small samples to larger numbers of participants can benefit HIV and STI prevention research.

HIV, STI prevalence and risk behaviours among women selling sex in Lahore, Pakistan

PubMed Central

2011-01-01

Background More than 340 million cases of curable sexually transmitted infections (STIs) were estimated to have occurred worldwide in 1995. Previous studies have shown that the presence of other concomitant STIs increases the likelihood of HIV transmission. The first national study of STIs conducted in Pakistan in 2004 revealed a high burden of STIs among women selling sex. The HIV epidemic in Pakistan has thus far followed the "Asian epidemic model". Earlier studies among women selling sex have shown a low prevalence of HIV coupled with a low level of knowledge about AIDS. The aim of our study was to estimate the prevalence of HIV and STIs, and assess knowledge and risk behaviours related to HIV/STI, among women selling sex in Lahore, Pakistan. Methods A total of 730 participants were recruited through respondent-driven sampling. The participants were women selling sex in three areas (referred to as "A", "B", and "C") of Lahore. A structured questionnaire addressing demographic information, sexual life history, sexual contacts, and knowledge and practices related to HIV/STI prevention was administered by face-to-face interview. Biological samples were obtained from all participants and tested for HIV, Treponema pallidum, Neisseria gonorrhoeae, Chlamydia trachomatis and Trichomonas vaginalis. Pearson's chi-square and multivariable logistic regression analysis were performed to test associations between potential risk factors and specified diagnosed infections. Results The prevalence of HIV infection was 0.7%, T pallidum 4.5%, N gonorrhoeae 7.5%, C trachomatis 7.7% and T vaginalis 5.1%. The participants had been selling sex for a median period of seven years and had a median of three clients per day. Sixty five percent of the participants reported that they "Always use condom". The median fee per sexual contact was Rs. 250 (3 Euro). Compared to Areas A and C, women selling sex in Area B had a significantly higher risk of chlamydial infection, gonorrhoea and

This paper provides an overview of ground based operational remote sensing activities that enable a broad range of missions at the Eastern Range (ER), which includes the National Aeronautics and Space Administration (NASA) Kennedy Space Center (KSC) and U.S. Air Force Cape Canaveral Air Force Station (CCAFS). Many types of sensors are in use by KSC and across the ER. We examine remote sensors for winds, lightning and electric fields, precipitation and storm hazards. These sensors provide data that are used in real-time to evaluate launch commit criteria during space launches, major ground processing operations in preparation for space launches, issuing weather warnings/watches/advisories to protect over 25,000 people and facilities worth over $20 billion, and routine weather forecasts. The data from these sensors are archived to focus NASA launch vehicle design studies, to develop forecast techniques, and for incident investigation. The wind sensors include the 50-MHz and 915-MHz Doppler Radar Wind Profilers (DRWP) and the Doppler capability of the weather surveillance radars. The atmospheric electricity sensors include lightning aloft detectors, cloud-to-ground lightning detectors, and surface electric field mills. The precipitation and storm hazards sensors include weather surveillance radars. Next, we discuss a new type of remote sensor that may lead to better tracking of near-Earth asteroids versus current capabilities. The Ka Band Objects Observation and Monitoring (KaBOOM) is a phased array of three 12 meter (m) antennas being built as a technology demonstration for a future radar system that could be used to track deep-space objects such as asteroids. Transmissions in the Ka band allow for wider bandwidth than at lower frequencies, but the signals are also far more susceptible to de-correlation from turbulence in the troposphere, as well as attenuation due to water vapor, which is plentiful in the Central Florida atmosphere. If successful, KaBOOM will have

NASA Earth Observations (NEO): Data Access for Informal Education and Outreach

2005-01-01

The NEO (NASA Earth Observations) web space is currently under development with the goal of significantly increasing the demand for NASA remote sensing data while dramatically simplifying public access to georeferenced images. NEO will target the unsophisticated, nontraditional data users who are currently underserved by the existing data ordering systems. These users will include formal and informal educators, museum and science center personnel, professional communicators, and citizen scientists and amateur Earth observers. Users will be able to view and manipulate georeferenced browse imagery and, if they desire, download directly or order the source HDF data from the data provider (e.g., NASA DAAC or science team) via a single, integrated interface. NE0 will accomplish this goal by anticipating users expectations and knowledge level, thus providing an interface that presents material to users in a more simplified manner, without relying upon the jargon/technical terminology that make even the identification of the appropriate data set a significant hurdle. NEO will also act as a gateway that manages users expectations by providing specific details about images and data formats, developing tutorials regarding the manipulation of georeferenced imagery and raw data, links to software tools and ensuring that users are able to get the image they want in the format they want as easily as possible.

2012-08-01

Homeless youth are at high risk for human immunodeficiency virus (HIV) and other sexually transmitted infections (STI), yet those at greatest risk may never have been tested for HIV or STI. In a probability sample of sexually active homeless youth in Los Angeles (n = 305), this study identifies factors associated with HIV/STI testing status. Most youth (85%) had ever been tested and 47% had been tested in the past 3 months. Recent testing was significantly more likely among youth who self-identified as gay, were Hispanic, injected drugs, and used drop-in centers, and marginally more likely among youth with more depressive symptoms. Drop-in center use mediated the association of injection drug use with HIV/STI testing. HIV/STI testing was unrelated to sexual risk behavior. Drop-in centers can play an important role in facilitating testing, including among injection drug users, but more outreach is needed to encourage testing in other at-risk subgroups.

There is increasing excitement about multimedia sexually transmitted infection (STI) and HIV prevention interventions, yet there has been limited discussion of how use of multimedia technology may improve STI/HIV prevention efforts. The purpose of this paper is to describe the mechanisms through which multimedia technology may work to improve the delivery and uptake of intervention material. We present conceptual frameworks describing how multimedia technology may improve intervention delivery by increasing standardization and fidelity to the intervention material and the participant's ability to learn by improving attention, cognition, emotional engagement, skills-building, and uptake of sensitive material about sexual and drug risks. In addition, we describe how the non-multimedia behavioral STI/HIV prevention intervention, Project WORTH, was adapted into a multimedia format for women involved in the criminal justice system and provide examples of how multimedia activities can more effectively target key mediators of behavioral change in this intervention.

Adaptation to stress triggers the most dramatic shift in gene expression in fission yeast ( Schizosaccharomyces pombe ), and this response is driven by signaling via the MAPK Sty1. Upon activation, Sty1 accumulates in the nucleus and stimulates expression of hundreds of genes via the nuclear transcription factor Atf1, including expression of atf1 itself. However, the role of stress-induced, Sty1-mediated Atf1 phosphorylation in transcriptional activation is unclear. To this end, we expressed Atf1 phosphorylation mutants from a constitutive promoter to uncouple Atf1 activity from endogenous, stress-activated Atf1 expression. We found that cells expressing a nonphosphorylatable Atf1 variant are sensitive to oxidative stress because of impaired transcription of a subset of stress genes whose expression is also controlled by another transcription factor, Pap1. Furthermore, cells expressing a phospho-mimicking Atf1 mutant display enhanced stress resistance, and although expression of the Pap1-dependent genes still relied on stress induction, another subset of stress-responsive genes was constitutively expressed in these cells. We also observed that, in cells expressing the phospho-mimicking Atf1 mutant, the presence of Sty1 was completely dispensable, with all stress defects of Sty1-deficient cells being suppressed by expression of the Atf1 mutant. We further demonstrated that Sty1-mediated Atf1 phosphorylation does not stimulate binding of Atf1 to DNA but, rather, establishes a platform of interactions with the basal transcriptional machinery to facilitate transcription initiation. In summary, our results provide evidence that Atf1 phosphorylation by the MAPK Sty1 is required for oxidative stress responses in fission yeast cells by promoting transcription initiation. © 2017 by The American Society for Biochemistry and Molecular Biology, Inc.

2012-01-01

To enhance future STI/HIV prevention efforts, this study examined factors associated with adolescents' failure to improve their condom use behaviors after participating in an STI/HIV prevention intervention. African-American adolescent females (N = 205; M age = 17.9) in an STI/HIV prevention intervention trial completed ACASI interviews and provided self-collected vaginal swabs to assess two prevalent STIs at baseline and 6 months after intervention. Analyses compared those who increased condom use after intervention (change group) to those whose condom use did not increase (nonchange group). 43.4% did not increase their condom use after the intervention and were more likely to have an STI at followup (χ 2 = 4.64, P = .03). In a multivariate logistic regression model, the nonchange group was more likely to have (a) higher sensation seeking (AOR = .91, P = .023), (b) a boyfriend (AOR = .32, P = .046), and/or (c) a physical abuse history (AOR = .56, P = .057). There were also differences in the extent to which psychosocial mediators changed between the two groups. Findings highlight the need to tailor STI/HIV interventions to adolescents with a greater degree of sensation seeking and address key relationship characteristics and trauma histories to bolster intervention efficacy.

Large-scale internal migration in China may be an important mechanism for the spread of HIV/sexually transmitted infections (STIs) because of the risk behaviours of migrants. We conducted a self-administered survey among 724 employees of a high-end entertainment centre in Kunshan, Jiangsu Province, China. Using logistic regression, we examined the association of hometown of origin (Kunshan city, elsewhere in Jiangsu Province, or another province in China) and consecutive years living in Kunshan with measures of HIV/STI risk behaviour. We found that increased time living in Kunshan was associated with lower odds of using condoms as contraception [odds ratio (OR) = 0.78, 95% confidence interval (CI): 0.64–0.95] and consistent condom use with a casual partner (OR = 0.66, 95% CI: 0.47–0.93), after controlling for gender, marital status age and income. The odds of having had an STI were significantly lower for Kunshan natives than those originally from outside provinces (OR = 0.25, 95% CI: 0.07–0.96), but increasing years living in Kunshan was not related to lower risk for an STI. Our findings do not support the hypothesis that migrants living far from home participate in higher risk behaviour than locals. Findings suggest that adaptation to local culture over time may increase HIV/STI risk behaviours, a troublesome finding. PMID:21389063

Youth report embarrassment, cost, and poor access as barriers to sexual and reproductive health (SRH) services. Interventions to address barriers like youth friendly services have yet to conclusively demonstrate impact on protective behaviours like condom or contraceptive use. SRH encompasses a range of services so we aimed to assess how perceived barriers differed depending on the service being sought between common services accessed by young people: HIV/STI testing, abortion, and contraception. 1203 Ghanaian youth were interviewed. Data was analysed to identify barriers by service type, demographics, and between high and low HIV prevalence communities. Being embarrassed or shy was the most commonly reported barrier across services. Overall being embarrassed or shy, fear of safety, fear of family finding out and cost were the most reported barriers across all services. Further analysis by service indicated that being embarrassed was a significantly greater barrier for HIV/STI testing and contraception when compared with abortion (p<0.001) and safety concerns and cost were significantly greater barriers for abortion and contraception compared with HIV/STI testing (p<0.001). Efforts to develop interventions that consider the service being sought may help address the range of barriers faced by youth with diverse SRH needs.

This paper describes the preliminary analysis of a survey of the American Institute of Aeronautics and Astronautics (AIAA) student members. In the paper we examine (1) the demographic characteristics of the students, (2) factors that affected their career decisions, (3) their career goals and aspirations, and (4) their training in technical communication and techniques for finding and using aerospace scientific and technical information (STI). We determine that aerospace engineering students receive training in technical communication skills and the use of STI. While those in the aerospace industry think that more training is needed, we believe the students receive the appropriate amount of training. We think that the differences between the amount of training students receive and the perception of training needs is related partially to the characteristics of the students and partially to the structure of the aerospace STI dissemination system. Overall, we conclude that the students' technical communication training and knowledge of STI, while limited by external forces, makes it difficult for students to achieve their career goals.

Exotic Dance in Baltimore: From Entry to STI/HIV Risk

Reuben, Jacqueline; Sherman, Susan G.

2015-01-01

Research has documented health risks associated with sex work, but few U.S. studies have focused on the exotic dance industry. We undertook to describe the factors that influenced women's entry into exotic dance and explored the relation of these forces to their subsequent Sexually Transmitted Infection (STI)/HIV risk trajectory. Qualitative interviews (N=25) were conducted with female exotic dancers from June through August, 2009. Data were analyzed through Atlas-ti using an inductive approach. Economic vulnerability was the primary force behind women's initiation into the profession. Drug use, physical abuse, and enjoyment of dancing were often concurrent with economic need and provided a further push toward exotic dance. Social networks facilitated entry by normalizing the profession and presenting it as a solution to financial hardship. Characteristics of exotic dance clubs, such as immediate hire and daily pay, attracted women in a state of financial vulnerability. Women's motivations for dancing, including economic vulnerability and drug use practices, shaped their STI/HIV risk once immersed in the club environment, with social networks often facilitating sexual risk behavior. Understanding the factors that drive women to exotic dance and influence risk behavior in the club may assist in the development of targeted harm reduction interventions for exotic dancers.

2016-01-01

The purpose of this study was to determine the prevalence and individual risk factors of people who trade or sell sex among sexually active individuals seeking HIV and sexually transmitted infection (STI) testing. Using electronic agency records, an analysis of the characteristics of 5,029 youth and adults who voluntarily obtained HIV and STI testing was conducted. Multiple imputation procedures for missing data from 3 variables and logistic regression were conducted. A total of 128 individuals reported having traded sex. Nine variables had statistically significant associations with trading sex. Individuals who identified as White and female had lesser odds of trading sex, whereas individuals who were transgender, were living in a shelter, had been sexually assaulted, had a previous STI, had high-risk sex, or used drugs had greater odds of trading sex. Elevated levels of high-risk behavior in addition to sexual trauma should be considered in intervention research and community health practice. Implications for service providers and researchers are discussed.

2017-01-01

Background Evolving health priorities and resource constraints mean that countries require data on trends in sexually transmitted infections (STI) burden, to inform program planning and resource allocation. We applied the Spectrum STI estimation tool to estimate the prevalence and incidence of active syphilis in adult women in Morocco over 1995 to 2016. The results from the analysis are being used to inform Morocco’s national HIV/STI strategy, target setting and program evaluation. Methods Syphilis prevalence levels and trends were fitted through logistic regression to data from surveys in antenatal clinics, women attending family planning clinics and other general adult populations, as available post-1995. Prevalence data were adjusted for diagnostic test performance, and for the contribution of higher-risk populations not sampled in surveys. Incidence was inferred from prevalence by adjusting for the average duration of infection with active syphilis. Results In 2016, active syphilis prevalence was estimated to be 0.56% in women 15 to 49 years of age (95% confidence interval, CI: 0.3%-1.0%), and around 21,675 (10,612–37,198) new syphilis infections have occurred. The analysis shows a steady decline in prevalence from 1995, when the prevalence was estimated to be 1.8% (1.0–3.5%). The decline was consistent with decreasing prevalences observed in TB patients, fishermen and prisoners followed over 2000–2012 through sentinel surveillance, and with a decline since 2003 in national HIV incidence estimated earlier through independent modelling. Conclusions Periodic population-based surveys allowed Morocco to estimate syphilis prevalence and incidence trends. This first-ever undertaking engaged and focused national stakeholders, and confirmed the still considerable syphilis burden. The latest survey was done in 2012 and so the trends are relatively uncertain after 2012. From 2017 Morocco plans to implement a system to record data from routine antenatal

HIV/STI Prevention Among Heterosexually Active Black Adolescents With Mental Illnesses: Focus Group Findings for Intervention Development.

PubMed

Brawner, Bridgette M; Jemmott, Loretta Sweet; Wingood, Gina; Reason, Janaiya; Mack, Niya

Heterosexually active Black adolescents with mental illnesses are at increased risk for sexually transmitted infections (STIs), including HIV. However, few HIV/STI prevention interventions exist for this demographic. We held seven focus groups (N = 33) to elucidate social, cultural, and psychological factors that influence HIV/STI risk-related sexual behaviors in this understudied population. Seven themes emerged: (a) Blackness and media portrayals, (b) Blackness as a source of cultural resilience and pride, (c) psychosocial determinants of condom use, (d) consequences of engaging in sexual activity, (e) attitudes and beliefs toward sexual behaviors, (f) benefits of sexual activity, and (g) coping mechanisms. Participants also supported the feasibility of and interest in HIV/STI prevention programs integrated with mental health treatment. Transportation, potential breaches of confidentiality, and time were noted barriers to participation. Psychoeducational, skills-based programs are needed to address the sequelae of mental illnesses as they relate to the sexual decision-making process in adolescents.

Incarcerated black women in the southern USA are understudied despite the high prevalence of sexually transmitted infections (STI) and human immunodeficiency virus (HIV). These incarceration and health disparities are rooted in centuries of historically inequitable treatment. Amidst the current dialogue on mass incarceration in the south and its relationship to the health of the black community, individual and environmental risk factors for STI/HIV transmission are seldom paired with discussions of evidence-based solutions. A narrative review of the literature from January 1995 to May 2015 was conducted. This sample of the literature (n = 18) revealed that partner concurrency, inconsistent condom use, sex work, previous STI, and drug abuse augmented individual STI/HIV risk. Recommended interventions include those which promote healthier relationships, cultural competence, and gender specificity, as well as those that enhance prevention skills. Policy recommendations include improving cultural sensitivity, cultural competence, and cultural humility training for clinicians, as well as substantially increasing funding for prevention, treatment, and rehabilitative services. These recommendations are timely given the recent national attention to incarceration, STI, and HIV disparities, particularly in the southern USA.

Delineation of voided and hydrocarbon contaminated regions with REDEM and STI

Whiteley, B.

1997-10-01

Undetected voids and cavernous regions at shallow depth are a significant geotechnical and environmental hazard if they are filled or act as conduits for pollutants, particularly for LNAPL and DNAPL contaminants. Such features are often difficult to locate with drilling and conventional geophysical methods including resistivity, electromagnetics, microgravity, seismic and ground penetrating radar when they occur in industrial or urban areas where electrical and vibrational interference can combine with subsurface complexity due to human action to severely degrade geophysical data quality. A new geophysical method called Radiowave Diffraction Electromagnetics (RDEM) has proved successful for rapid screening of difficult sites andmore » for the delineation of buried sinkholes, cavities and hydrocarbon plumes. RDEM operates with a null coupled coil configuration at about 1.6 MHZ and is relatively insensitive to electrical interference and surrounding metal objects. It responds to subsurface variations in both conductivity and dielectric constant. Voided and contaminated regions can be more fully detailed when RDEM is combined with Seismic Tomographic Imaging (STI) from follow-up boreholes. Case studies from sites in Australia and South East Asia demonstrate the application of RDEM and STI and the value in combining both methods.« less

Thresholds of information leakage for speech security outside meeting rooms.

PubMed

Robinson, Matthew; Hopkins, Carl; Worrall, Ken; Jackson, Tim

2014-09-01

This paper describes an approach to provide speech security outside meeting rooms where a covert listener might attempt to extract confidential information. Decision-based experiments are used to establish a relationship between an objective measurement of the Speech Transmission Index (STI) and a subjective assessment relating to the threshold of information leakage. This threshold is defined for a specific percentage of English words that are identifiable with a maximum safe vocal effort (e.g., "normal" speech) used by the meeting participants. The results demonstrate that it is possible to quantify an offset that links STI with a specific threshold of information leakage which describes the percentage of words identified. The offsets for male talkers are shown to be approximately 10 dB larger than for female talkers. Hence for speech security it is possible to determine offsets for the threshold of information leakage using male talkers as the "worst case scenario." To define a suitable threshold of information leakage, the results show that a robust definition can be based upon 1%, 2%, or 5% of words identified. For these percentages, results are presented for offset values corresponding to different STI values in a range from 0.1 to 0.3.

University Program Management Information System: NASA's University Program Active Projects

As basic policy, NASA believes that colleges and universities should be encouraged to participate in the nation's space and aeronautics program to the maximum extent practicable. Indeed, universities are considered as partners with government and industry in the nation's aerospace program. NASA's objective is to have them bring their scientific, engineering, and social research competence to bear on aerospace problems and on the broader social, economic, and international implications of NASA's technical and scientific programs. It is expected that, in so doing, universities will strengthen both their research and their educational capabilities to contribute more effectively to the national well being. This annual report is one means of documenting the NASA-university relationship, frequently denoted, collectively, as NASA's University Program.

Gonorrhoea, caused by Neisseria gonorrhoeae (NG), can cause reproductive morbidity, is increasingly becoming resistant to antibiotics and is frequently asymptomatic, which shows the essential role of NG test practice. In this study we wanted to compare NG diagnostic testing procedures between different STI care providers serving a defined geographic Dutch region (280,000 inhabitants). Data on laboratory testing and diagnosis of urogenital and extragenital (i.e. anorectal and oropharyngeal) NG were retrieved from general practitioners (GPs), an STI clinic, and gynaecologists (2006-2010). Per provider, we assessed their contribution regarding the total number of tests performed and type of populations tested, the proportion of NG positives re-tested (3-12 months after treatment) and test-of-cure (TOC, within 3 months post treatment). Overall, 17,702 NG tests (48.7% STI clinic, 38.2% GPs, 13.1% gynaecologists) were performed during 15,458 patient visits. From this total number of tests, 2257 (12.7%) were extragenital, of which 99.4% were performed by the STI clinic. Men were mostly tested at the STI clinic (71%) and women by their GP (43%). NG positivity per visit was 1.6%; GP 1.9% (n = 111), STI clinic 1.7% (n = 131) and gynaecology 0.2% (n = 5). NG positivity was associated with Chlamydia trachomatis positivity (OR: 2.06, 95% confidence interval: 1.46-2.92). Per anatomical location, the proportion of NG positives re-tested were: urogenital 20.3% (n = 36), anorectal 43.6% (n = 17) and oropharyngeal 57.1% (n = 20). NG positivity among re-tests was 16.9%. Proportions of NG positives with TOC by anatomical location were: urogenital 10.2% (n = 18), anorectal 17.9% (n = 7) and oropharyngeal 17.1% (n = 6). To achieve best practice in relation to NG testing, we recommend that: 1) GPs test at extragenital sites, especially men who have sex with men (MSM), 2) all care providers consider re-testing 3 to 12 months after NG diagnosis and 3) TOC is performed

Background HIV/sexually transmitted infections (STIs) and drug abuse remain significant public health concerns in the United States, and African American and Hispanic youth are disproportionately affected. Although technology-based interventions are efficacious in preventing and reducing HIV/STI and licit/illicit drug use behaviors, relatively little is known regarding the state of the science of these interventions among African American and Hispanic youth. Objective The aim of this review is to identify and examine randomized controlled trials (RCTs) of technology-based HIV/STI and/or drug abuse preventive interventions for African American and Hispanic youth. Methods We searched electronic databases (ie, PubMed, Proquest, PsycINFO, Ebscohost, Google Scholar) to identify studies between January 2006 and October 2016. RCTs of technology-based interventions targeting African American and Hispanic youth HIV/STI risk behaviors, including sexual risk, licit and illicit drug use, and HIV/STI testing were included. Results Our search revealed a total of three studies that used an RCT design and included samples comprised of >50% African American and/or Hispanic youth. The follow-up assessments ranged from two weeks to six months and the number of participants in each trial ranged from 72 to 141. The three interventions were theory-driven, interactive, and tailored. The long-term effects of the interventions were mixed, and outcomes included reductions in sex partners, licit drug use, and condomless anal sex acts. Conclusions Although technology-based interventions seem promising in the prevention of HIV/STI and drug abuse among African American and Hispanic youth, more research is needed. PMID:29237577

This article presents data about the relationship between alcohol consumption prior to sex and unprotected sex and the prevalence of at least one sexually transmitted infection (STI) including HIV among socially marginalized men in three coastal Peruvians cities. During an epidemiological survey with 2,146 men, we assessed their STI prevalence, frequency of alcohol consumption prior to sex, unprotected sex and other sexual risk behaviors. The overall prevalence of at least one STI/HIV was 8.5 % (95 % CI 7.3–9.7), the prevalence of unprotected sex was 79.1 % (95 % CI 77.8–80.3) and alcohol consumption prior to sex with any of the last five sex partners in the previous 6 months was 68.9 % (95 % CI 66.9–70.9). Bivariate and multivariate analysis showed that alcohol consumption of participants or their partners prior to sex were associated with the prevalence of at least one STI, adjusted Prevalence Ratio (aPR) = 1.3 (95 % CI 1.01–1.68). Unprotected sex was significantly associated with alcohol consumption prior to sex when both partners used alcohol, aPR = 1.15 (95 % CI 1.10–1.20) or when either one of them used alcohol aPR = 1.14 (95 % CI 1.09–1.18). These findings concur with previous literature suggesting a relationship between alcohol consumption prior to sex and STI and HIV. These data improve our understanding of this relationship in this context and could be used to enhance STI and HIV prevention strategies for socially marginalized men in Peru. PMID:23054035

2017-12-01

In conjunction with a 3-year prospective study of 199 transgender women from the New York City Area, we attempted to better understand why non-Whites are much more likely than Whites to become HIV infected. We first assessed associations of ethnicity with sex work, sexual risk behavior for HIV, and biologically-determined HIV/STI, and then assessed the extent to which these ethnic differences are explained by socioeconomic factors, immigration status, and sexual orientation. Statistical techniques included generalized estimating equations and Cox proportional hazards. As expected, compared to Whites, Blacks and Hispanics were more involved in the sex trade, more likely to report unprotected receptive anal intercourse, and as a result, more likely to become HIV/STI infected. All of these associations were mediated by androphilia, and to a lesser extent androphilia/gynephilia. Sexual orientation is a significant but little recognized factors associated with new cases of HIV/STI among transgender women of color.

NASA Systems Engineering Handbook

NASA Technical Reports Server (NTRS)

2007-01-01

This handbook is intended to provide general guidance and information on systems engineering that will be useful to the NASA community. It provides a generic description of Systems Engineering (SE) as it should be applied throughout NASA. A goal of the handbook is to increase awareness and consistency across the Agency and advance the practice of SE. This handbook provides perspectives relevant to NASA and data particular to NASA. The coverage in this handbook is limited to general concepts and generic descriptions of processes, tools, and techniques. It provides information on systems engineering best practices and pitfalls to avoid. There are many Center-specific handbooks and directives as well as textbooks that can be consulted for in-depth tutorials. This handbook describes systems engineering as it should be applied to the development and implementation of large and small NASA programs and projects. NASA has defined different life cycles that specifically address the major project categories, or product lines, which are: Flight Systems and Ground Support (FS&GS), Research and Technology (R&T), Construction of Facilities (CoF), and Environmental Compliance and Restoration (ECR). The technical content of the handbook provides systems engineering best practices that should be incorporated into all NASA product lines. (Check the NASA On-Line Directives Information System (NODIS) electronic document library for applicable NASA directives on topics such as product lines.) For simplicity this handbook uses the FS&GS product line as an example. The specifics of FS&GS can be seen in the description of the life cycle and the details of the milestone reviews. Each product line will vary in these two areas; therefore, the reader should refer to the applicable NASA procedural requirements for the specific requirements for their life cycle and reviews. The engineering of NASA systems requires a systematic and disciplined set of processes that are applied recursively and

To explain rising rates of sexually transmitted infections it is necessary to monitor trends among high risk groups, such as youth. Surveillance of risk behaviours and testing among a variety of populations in different settings is required. We monitored self-reported sexual behaviour among music festival attendees. Cross-sectional studies of young people's behaviour were conducted annually at a music festival between 2005 and 2008 using self-administered questionnaires. Logistic regression, adjusted for age and gender, determined trends in risk behaviours. More than 5,000 questionnaires were completed. The proportion reporting multiple sexual partners in the past year remained stable from 2005 to 2008 and condom use with these partners increased. Reporting a new sexual partner in the past three months decreased, while condom use with new partners increased. Reporting a casual sexual partner increased and condom use with casual partners remained stable. Reporting a recent STI test increased from 23% in 2006 to 32% in 2008. Despite increases in STI notifications, most risk behaviours are decreasing in this group, possibly as a function of increased STI testing. Music festivals are a useful setting for monitoring behaviour trends within a sub-population of young people at relatively high risk of STIs.

NASA produces vast amounts of information about the Earth from satellites, supercomputer models, and other sources. These data are most useful when made easily accessible to NASA researchers and scientists, to NASA's partner Federal Agencies, and to society as a whole. A NASA goal is to apply its data for knowledge gain, decision support and understanding of Earth, and other planetary systems. The NASA Earth Science Enterprise (ESE) Geospatial Interoperability Office (GIO) Program leads the development, promotion and implementation of information technology standards that accelerate and expand the delivery of NASA's Earth system science research through integrated systems solutions. Our overarching goal is to make it easy for decision-makers, scientists and citizens to use NASA's science information. NASA's Federal partners currently participate with NASA and one another in the development and implementation of geospatial standards to ensure the most efficient and effective access to one another's data. Through the GIO, NASA participates with its Federal partners in implementing interoperability standards in support of E-Gov and the associated President's Management Agenda initiatives by collaborating on standards development. Through partnerships with government, private industry, education and communities the GIO works towards enhancing the ESE Applications Division in the area of National Applications and decision support systems. The GIO provides geospatial standards leadership within NASA, represents NASA on the Federal Geographic Data Committee (FGDC) Coordination Working Group and chairs the FGDC's Geospatial Applications and Interoperability Working Group (GAI) and supports development and implementation efforts such as Earth Science Gateway (ESG), Space Time Tool Kit and Web Map Services (WMS) Global Mosaic.

Objectives To explore the experiences and views of men who have sex with men (MSM) on attending clinical sexual health services and their preferences regarding service characteristics in the context of the disproportionate burden of STIs experienced by this group. The wider study aim was to develop a risk assessment tool for use in sexual health clinics. Methods Qualitative study comprising eight focus group discussions with 61 MSM in four English cities. Topics included: experience of attending sexual health services, perceptions of norms of attendance among MSM, knowledge of, and attitudes towards, STIs and views on ‘being researched.’ Discussions were audio-recorded and transcribed and a thematic data analysis conducted. Results Attending sexual health services for STI testing was described as embarrassing by some and some clinic procedures were thought to compromise confidentiality. Young men seeking STI testing were particularly sensitive to feelings of awkwardness and self-consciousness. Black and ethnic minority men were concerned about being exposed in their communities. The personal qualities of staff were seen as key features of sexual health services. Participants wanted staff to be friendly, professional, discreet, knowledgeable and non-judgemental. Conclusions A range of opinion on the type of STI service men preferred was expressed with some favouring generic sexual and reproductive health clinics and others favouring specialist community-based services. There was consensus on the qualities they would like to see in healthcare staff. The knowledge, conduct and demeanour of staff could exacerbate or ameliorate unease associated with attending for STI testing. PMID:28778980

Despite widespread biomedical advances in treatment, HIV and other sexually transmitted infections (STI) continue to affect a large portion of the world's population. The profoundly social nature of behaviorally driven epidemics and disparities across socioeconomic divides in the distribution of HIV/STI and care outcomes emphasize the need for innovative, multilevel interventions. Interdisciplinary approaches to HIV/STI control are needed to combine insights from the social and biological sciences and public health fields. In this concluding essay to a Special Issue on HIV/STI in south China, we describe the evolution of China's HIV/STI epidemics and the government response; then synthesize findings from the 11 studies presented in this issues to extend seven recommendations for future HIV/STI prevention and care research in China. We discuss lessons learned from forging international collaborations between social science and public health to inform a shared research agenda to better meet the needs of those most affected by HIV and other STI.

The National Aeronautics and Space Act of 1958 established NASA and charged it to "provide for the widest practicable and appropriate dissemination of information concerning its activities and the results thereof." The search for innovative methods to distribute NASA's information lead a grass-roots team to create the NASA Technical Report Server (NTRS), which uses the World Wide Web and other popular Internet-based information systems as search engines. The NTRS is an inter-center effort which provides uniform access to various distributed publication servers residing on the Internet. Users have immediate desktop access to technical publications from NASA centers and institutes. The NTRS is comprised of several units, some constructed especially for inclusion in NTRS, and others that are existing NASA publication services that NTRS reuses. This paper presents the NTRS architecture, usage metrics, and the lessons learned while implementing and maintaining the service. The NTRS is largely constructed with freely available software running on existing hardware. NTRS builds upon existing hardware and software, and the resulting additional exposure for the body of literature contained ensures that NASA's institutional knowledge base will continue to receive the widest practicable and appropriate dissemination.

NASA Uniform Files Index

This handbook is a guide for the use of all personnel engaged in handling NASA files. It is issued in accordance with the regulations of the National Archives and Records Administration, in the Code of Federal Regulations Title 36, Part 1224, Files Management; and the Federal Information Resources Management Regulation, Subpart 201-45.108, Files Management. It is intended to provide a standardized classification and filing scheme to achieve maximum uniformity and ease in maintaining and using agency records. It is a framework for consistent organization of information in an arrangement that will be useful to current and future researchers. The NASA Uniform Files Index coding structure is composed of the subject classification table used for NASA management directives and the subject groups in the NASA scientific and technical information system. It is designed to correlate files throughout NASA and it is anticipated that it may be useful with automated filing systems. It is expected that in the conversion of current files to this arrangement it will be necessary to add tertiary subjects and make further subdivisions under the existing categories. Established primary and secondary subject categories may not be changed arbitrarily. Proposals for additional subject categories of NASA-wide applicability, and suggestions for improvement in this handbook, should be addressed to the Records Program Manager at the pertinent installation who will forward it to the NASA Records Management Office, Code NTR, for approval. This handbook is issued in loose-leaf form and will be revised by page changes.

Education has long been considered a protective factor against sexual risk behaviors and sexually transmitted infections (STIs) among adolescents; however, few have explored this association and determined differences across racial/ethnic groups of young adult females on a national scale. The purpose of this study was to (1) describe the association between education and STI diagnosis among a national sample of black and white young adult females and (2) examine racial differences in this association. We used data from the National Longitudinal Study of Adolescent Health (Add Health) to assess the association between education and chlamydia, gonorrhea, and/or trichomoniasis (self-reported and assay-diagnosed) in 2001-2002 using logistic regression analysis. After adjustment for risk behaviors, education was inversely associated with any assay-diagnosed STI, but this association was nonsignificant among black women for self-reported STI. Additionally, black females enrolled in, or who graduated from, college had significantly higher predicted probabilities of having an STI (12.4% self-reported; 13.4% assay-diagnosed) compared with white females who had less than a high school diploma (6.4% self-reported; 2.3% assay-diagnosed). Educational status was not uniformly protective against STIs for black and white females in this sample. Particularly for young black women, other factors may play a more prominent role in determining STI risk. Social determinants, such as education, should be viewed as important factors associated with STI prevalence, but their differential impact on various racial/ethnic groups should also be considered when addressing the disproportionate rates of STIs in the U.S.

The NASA Science Education and Public Outreach Forums have developed a digital library--NASAWavelength.org--that enables easy discovery and retrieval of thousands of resources from the NASA Earth and space science education portfolio. The system has been developed based on best practices in the architecture and design of web-based information systems. The design style and philosophy emphasize simple, reusable data and services that facilitate the free flow of data across systems. The primary audiences for NASA Wavelength are STEM educators (K-12, higher education and informal education) as well as scientists, education and public outreach professionals who work with K-12, higher education, and informal education. A NASA Wavelength strandmap service features the 19 AAAS strandmaps that are most relevant to NASA science; the service also generates all of the 103 AAAS strandmaps with content from the Wavelength collection. These maps graphically and interactively provide connections between concepts as well as illustrate how concepts build upon one another across grade levels. New features have been developed for this site based on user feedback, including list-building so that users can create and share individual collections within Wavelength. We will also discuss potential methods for integrating the Next Generation Science Standards (NGSS) into the search and discovery tools on NASA Wavelength.

The U.S. Bureau of Reclamation identified the remote sensing of evapotranspiration (ET) as an important water flux for study and designated a test site in the Lower Colorado River basin. A consortium of groups will work together with the goal to develop more accurate and cost effective techniques using the enhanced spatial and temporal coverage afforded by remote sensing. ET is a critical water loss flux where improved estimation should lead to better management of Reclamation responsibilities. There are several areas where NASA satellite and modeling data may be useful to meet Reclamation's objectives for improved ET estimation. In this paper we outline one possible contribution to use NASA's data integration capability of the Land Information System (LIS) to provide a merger of observational (in situ and satellite) with physical process models to provide estimates of ET and other water availability outputs (e.g., runoff, soil moisture) retrospectively, in near real-time, and also providing short-term predictions.

Seeking sexual health information online is common, and provision of mobile medical applications (apps) for STIs is increasing. Young people, inherently at higher risk of STIs, are avid users of technology, and apps could be appealing sources of information. We undertook a comprehensive review of content and accuracy of apps for people seeking information about STIs. Search of Google Play and iTunes stores using general and specific search terms for apps regarding STIs and genital infections (except HIV), testing, diagnosis and management, 10 September 2014 to 16 September 2014. We assessed eligible apps against (1) 19 modified Health on The Net (HON) Foundation principles; and (2) comprehensiveness and accuracy of information on STIs/genital infections, and their diagnosis and management, compared with corresponding National Health Service STI information webpage content. 144/6642 apps were eligible. 57 were excluded after downloading. 87 were analysed. Only 29% of apps met ≥6 HON criteria. Content was highly variable: 34/87 (39%) covered one or two infections; 40 (46%) covered multiple STIs; 5 (6%) focused on accessing STI testing. 13 (15%) were fully, 46 (53%) mostly and 28 (32%) partially accurate. 25 (29%) contained ≥1 piece of potentially harmful information. Apps available on both iOS and Android were more accurate than single-platform apps. Only one app provided fully accurate and comprehensive information on chlamydia. Marked variation in content, quality and accuracy of available apps combined with the nearly one-third containing potentially harmful information risks undermining potential benefits of an e-Health approach to sexual health and well-being.

Teitelman, Anne M.; Ratcliffe, Sarah J.; Cederbaum, Julie A.

2011-01-01

Racial/ethnic minority adolescent girls bear a disproportionate risk for HIV and face barriers to autonomous sexual decision making, but parental messages may help protect against sexual risk taking. The authors examined African American and Hispanic girls’ sexually transmitted infection (STI) and HIV prevention practices, parent–adolescent communication about sexual pressure, and maternal gender norms (N = 118). Teens were more likely to practice consistent STI/HIV prevention when mothers talked about partner sexual pressure (p = .017) and fathers talked about resisting partner sexual pressure (p = .034). Sexually active girls who perceived that their mothers held egalitarian beliefs about partner decision making had more consistent condom use (p = .029). Given the context of increased STI/HIV risk, it is critical that parents discuss partner dynamics with daughters. Nurses play a unique role in facilitating these conversations; they provide parents with age-appropriate resources and assist in normalizing fears, which can help increase parent–child sexual-risk communication.

Role-based sexual identities structure male same-sex partnerships and influence HIV/STI epidemiology among MSM in Latin America. We explored shifting relationships between sexual roles, identities and practices among MSM in Lima, Peru, and implications for HIV/STI prevention. Patterns of HIV/STI epidemiology reflected differential risks for transmission within role-based partnerships with relatively low prevalences of HIV, syphilis, and HSV-2 but higher prevalences of urethral gonorrhea/chlamydia among activo MSM compared with moderno and pasivo participants. Qualitative analysis of how MSM in Peru integrate sexual identities, roles, and practices identified four key themes: pasivo role as a gay approximation of cultural femininity; activo role as a heterosexual consolidation of masculinity; moderno role as a masculine reconceptualization of gay identity; and role-based identities as social determinants of partnership, network, and community formation. The concept of role-based sexual identities provides a framework for HIV prevention for Latin American MSM that integrates sexual identities, practices, partnerships, and networks.

The goal is the creation of a generally accepted, systematically developed and implemented, but user focused, research agenda for the Advisory Group for Aerospace Research and Development (AGARD) and the Technical Information Panel (TIP) member countries. Information use seldom exists as an isolated incident. Information use usually takes place within organizational and interpersonal contexts. Therefore, it should not be studied in isolation, but rather in an holistic environment. Once implemented, this research agenda could be completed within 3 to 5 years. The results would be generalizable to AGARD member nations, would form the basis for the development of theory based practice, and would form a significant body of knowledge that can be used by AGARD information professionals for policy, practice, product, and systems development.
