Beta cloth durability assessment for Space Station Freedom (SSF) Multi-Layer Insulation (MLI) blanket covers

MLI blankets for the Space Station Freedom (SSF) must comply with general program requirements and recommendations for long life and durability in the low-Earth orbit (LEO) environment. Atomic oxygen and solar ultraviolet/vacuum ultraviolet are the most important factors in the SSF natural environment which affect materials life. Two types of Beta cloth (Teflon coated woven glass fabric), which had been proposed as MLI blanket covers, were tested for long-term durability in the LEO environment. General resistance to atomic oxygen attack and permeation were evaluated in the high velocity atomic oxygen beam system at Los Alamos National Laboratories. Long-term exposure to the LEO environment was simulated in the laboratory using a radio frequency oxygen plasma asher. The plasma asher treated Beta cloth specimens were tested for thermo-optical properties and mechanical durability. Space exposure data from the Long Duration Exposure Facility and the Intelsat Solar Array Coupon were also used in the durability assessment. Beta cloth fabricated to Rockwell specification MBO 135-027 (Chemglas 250) was shown to have acceptable durability for general use as an MLI blanket cover material in the LEO environment while Sheldahl G414500 should be used only in locations which are protected from direct Ram atomic oxygen

Community Building, Community Bridging

A summary document of our research, entitled "Community Building, Community Bridging: Linking Neighborhood Improvement Initiatives and the New Regionalism in the San Francisco Bay Area," discusses the three initiatives and draws general lessons for those interested in how communities and regions could better work together

Predictors of Paternal Involvement in Childcare in Dual-Earner Families With Young Children

Dual-earner parents (N = 119) of preschool children enrolled in licensed childcare centers completed anonymous questionnaires that examined work and family variables as related to paternal involvement in three areas: engagement (i.e., one-on-one interaction with the child), responsibility (i.e., taking care of the child’s needs), and accessibility (i.e., being available to the child without directly interacting). Paternal responsibility was predicted by beliefs about fathering and structural variables (e.g., hours fathers and mothers worked). The percentage of time fathers spent as their child’s primary caregiver was predicted by structural variables (e.g., mothers’ work hours) and belief variables (e.g., men’s beliefs about fathering and fathers’ parenting self-efficacy). Paternal engagement and accessibility were not significantly predicted by any of the constructs examined

Using local citation data to relate the use of journal articles by academic researchers to the coverage of full-text document access systems

The methodology and findings are presented of an empirical study comparing local citation patterns with the holdings lists of a number of sources of journal articles. These sources were the British Library Document Supply Centre (BLDSC and the BL inside service, library holdings, ProQuest Direct, SearchBank, EiText and a linking system including both the Geobase database and the BLDSC. The value of local citation figures is discussed, as is the concept of a 'core' of journal titles, from both theoretical and practical perspectives. Using these figures to represent the local use of journal articles, the coverage of the document sources was found to vary widely. Unsurprisingly, the BLDSC was found to offer the widest coverage. Newer, electronic systems generally fared less well, but may offer other advantages

Tibia Fracture Walking Boot: A Strain Controlling Device

The group designed a non-invasive strain application device that improved upon existing fracture healing devices such as external fixators, casts, and functional braces. The design included combining an AirCast walking boot and patellar tendon bearing (PTB) brace, with the ability to create a gap beneath the heel. Three tests were used to verify the mechanical properties of the analogue bones, the strains at the fracture site produced by various forces, and the forces experienced at different locations on the foot while wearing the device. Through proof of concept, the testing showed that introducing a gap in the device correlates to a dampened force and strain at the fracture site for optimal healing conditions

Tools for implementing an evidence-based approach in public health practice

Increasing disease rates, limited funding, and the ever-growing scientific basis for intervention demand the use of proven strategies to improve population health. Public health practitioners must be ready to implement an evidence-based approach in their work to meet health goals and sustain necessary resources. We researched easily accessible and time-efficient tools for implementing an evidence-based public health (EBPH) approach to improve population health. Several tools have been developed to meet EBPH needs, including free online resources in the following topic areas: training and planning tools, US health surveillance, policy tracking and surveillance, systematic reviews and evidence-based guidelines, economic evaluation, and gray literature. Key elements of EBPH are engaging the community in assessment and decision making; using data and information systems systematically; making decisions on the basis of the best available peer-reviewed evidence (both quantitative and qualitative); applying program-planning frameworks (often based in health-behavior theory); conducting sound evaluation; and disseminating what is learned

The role of researchers in disseminating evidence to public health practice settings: A cross-sectional study

BACKGROUND: Evidence-based public health interventions, which research has demonstrated offer the most promise for improving the population’s health, are not always utilized in practice settings. The extent to which dissemination from researchers to public health practice settings occurs is not widely understood. This study examines the extent to which public health researchers in the United States are disseminating their research findings to local and state public health departments. METHODS: In a 2012, nationwide study, an online questionnaire was administered to 266 researchers from the National Institutes of Health, the Centers for Disease Control and Prevention, and universities to determine dissemination practices. Logistic regression analyses were used to examine the association between dissemination to state and/or local health departments and respondent characteristics, facilitators, and barriers to dissemination. RESULTS: Slightly over half of the respondents (58%) disseminated their findings to local and/or state health departments. After adjusting for other respondent characteristics, respondents were more likely to disseminate their findings to health departments if they worked for a university Prevention Research Center or the Centers for Disease Control and Prevention, or received their degree more than 20 years ago. Those who had ever worked in a practice or policy setting, those who thought dissemination was important to their own research and/or to the work of their unit/department, and those who had expectations set by their employers and/or funding agencies were more likely to disseminate after adjusting for work place, graduate degree and/or fellowship in public health, and the year the highest academic degree was received. CONCLUSIONS: There is still room for improvement in strengthening dissemination ties between researchers and public health practice settings, and decreasing the barriers researchers face during the dissemination process. Researchers could better utilize national programs or workshops, knowledge brokers, or opportunities provided through academic institutions to become more proficient in dissemination practices
