Front‐line perspectives on ‘joined‐up’ working relationships: a qualitative study of social prescribing in the west of Scotland

Cross-sector collaboration has been promoted by government policies in the United Kingdom and many western welfare states for decades. Literature on joint working has focused predominantly on the strategic level, neglecting the role of individual practitioners in putting ‘joined-up working’ into practice. This paper takes the case of ‘social prescribing’ in the West of Scotland as an instance of joined-up working, in which primary healthcare professionals are encouraged to refer patients to non-medical sources of support in the third sector. This study draws on social capital theory to analyse the quality of the relationships between primary healthcare professionals and third sector practitioners. Eighteen health professionals and 15 representatives of third sector organisations participated in a qualitative interview study. Significant barriers to collaborative working were evident. The two stakeholder groups expressed different understandings of health, with few primary healthcare professionals considering non-medical sources of support to be useful or relevant. Health professionals were mistrustful of unknown third sector organisations, and concerned about their accountability for referrals that were not successful or positive for the patient. Third sector practitioners sought to build trust through face-to-face interactions with health professionals. However, primary healthcare professionals and third sector practitioners were not connected in effective networks. We highlight the on-going imbalance of power between primary healthcare professionals and third sector organisations. Strategic collaborations should be complemented by efforts to build shared understandings, trust and connections between the diverse frontline workers whose mutual co-operation is necessary to achieve effective joined-up working

Radiation Testing of PICA at the Solar Power Tower

Sandia National Laboratory's Solar Power Tower was used to irradiate specimens of Phenolic Impregnated Carbon Ablator (PICA), in order to evaluate whether this thermal protection system material responded differently to potential shock layer radiative heating than to convective heating. Tests were run at 50, 100 and 150 Watts per square centimeter levels of concentrated solar radiation. Experimental results are presented both from spectral measurements on 1- 10 mm thick specimens of PICA, as well as from in-depth temperature measurements on instrumented thicker test specimens. Both spectral measurements and measured in-depth temperature profiles showed that, although it is a porous, low-density material, PICA does not exhibit problematic transparency to the tested high levels of NIR radiation, for all pragmatic cm-to-inch scale thicknesses. PICA acted as a surface absorber to efficiently absorb the incident visible and near infrared incident radiation in the top 2 millimeter layer in the Solar Power Tower tests up to 150 Watts per square centimeter

Fibrous-Ceramic/Aerogel Composite Insulating Tiles

Fibrous-ceramic/aerogel composite tiles have been invented to afford combinations of thermal-insulation and mechanical properties superior to those attainable by making tiles of fibrous ceramics alone or aerogels alone. These lightweight tiles can be tailored to a variety of applications that range from insulating cryogenic tanks to protecting spacecraft against re-entry heating. The advantages and disadvantages of fibrous ceramics and aerogels can be summarized as follows: Tiles made of ceramic fibers are known for mechanical strength, toughness, and machinability. Fibrous ceramic tiles are highly effective as thermal insulators in a vacuum. However, undesirably, the porosity of these materials makes them permeable by gases, so that in the presence of air or other gases, convection and gas-phase conduction contribute to the effective thermal conductivity of the tiles. Other disadvantages of the porosity and permeability of fibrous ceramic tiles arise because gases (e.g., water vapor or cryogenic gases) can condense in pores. This condensation contributes to weight, and in the case of cryogenic systems, the heat of condensation undesirably adds to the heat flowing to the objects that one seeks to keep cold. Moreover, there is a risk of explosion associated with vaporization of previously condensed gas upon reheating. Aerogels offer low permeability, low density, and low thermal conductivity, but are mechanically fragile. The basic idea of the present invention is to exploit the best features of fibrous ceramic tiles and aerogels. In a composite tile according to the invention, the fibrous ceramic serves as a matrix that mechanically supports the aerogel, while the aerogel serves as a low-conductivity, low-permeability filling that closes what would otherwise be the open pores of the fibrous ceramic. Because the aerogel eliminates or at least suppresses permeation by gas, gas-phase conduction, and convection, the thermal conductivity of such a composite even at normal atmospheric pressure is not much greater than that of the fibrous ceramic alone in a vacuum

Failure to meet aerobic fitness standards among urban elementary students

The aim of this study was to explore the relationship of aerobic fitness with the elementary school environment and student characteristics among 4th and 5th grade children attending urban public schools in St. Louis, MO, USA. This cross-sectional study was conducted during 2012–2015 and included 2381 children (mean age 10.5 y) who completed the FITNESSGRAM® 20-m Progressive Aerobic Cardiovascular Endurance Run. Healthy Fitness Zone (HFZ) was defined according to FITNESSGRAM® aerobic capacity criteria. Other student-level variables included age, race, National School Lunch Program eligibility, BMI z-score, weight status, and daily pedometer steps. School environment variables included playground features and playground safety, physical education and recess practices, and school census tract data on vacant houses and median household income. Bivariate analyses with sex stratification were used to identify student-level and school-level predictors of failure to achieve the aerobic HFZ; predictors were then included in a multivariable logistic regression model. Failure to meet the aerobic HFZ was observed among 33% of boys and 57% of girls. School environment was not predictive, but higher age and fewer daily steps were: each additional year of age was associated with 41% higher odds of failing to meet the aerobic HFZ among boys and 100% higher odds among girls. Conversely, each additional 1000 daily steps was associated with 15% (boys) and 13% (girls) lower odds of failure. Obesity posed a 60% higher risk of failure to meet HFZ among girls. These results highlight the importance of childhood physical activity opportunities, especially for girls residing in low-resource areas.

Effects of Laser Wavelength on Ablator Testing

Wavelength-dependent or spectral radiation effects are potentially significant for thermal protection materials. NASA atmospheric entry simulations include trajectories with significant levels of shock layer radiation which is concentrated in narrow spectral lines. Tests using two different high powered lasers, the 10.6 micron LHMEL I CO2 laser and the near-infrared 1.07 micron fiber laser, on low density ablative thermal protection materials offer a unique opportunity to evaluate spectral effects. Test results indicated that the laser wavelength can impact the thermal response of an ablative material, in terms of bond-line temperatures, penetration times, mass losses, and char layer thicknesses

The Changing Landscape of Race, Culture, and Family Life: Interracial Couples' Contribution to the Conversation

The published social science research on interracial marriages has burgeoned considerably over the past few decades as experts address not only traditional, but also emerging questions about the quality of life in mixed-race families. The "emic" experience of being in a mixed race family remains, though, a relatively under-explored topic. To help fill the gap, we conducted a nationally distributed, snowball sample, anonymous, online survey of 241 married or cohabiting individuals; 83.6% self-identified as a member of a bi-racial couple. The 131 items surveyed couples' experiences of their partnership, family life, support, and discrimination—both in time and in place. The study presented multiple findings including a persistence of race discrimination in neighborhoods and at work; surprisingly, the couples also reported that their children were allowed to play with the children of White neighbors, regardless of the racial makeup of the family. There was a significant relationship between "importance of falling in love" and the racial makeup of the couple (x2 (15, N=205) =30.42, p=.01); Black/White and Hispanic/White couples choose their partner for love. Moreover, same race couples expressed the most unhappiness and the most regret of all of the couple-groups surveyed. Most concerning, though, was that interracial couples perceive raising multiracial children as more difficult; these results were significant (x2 (30, N=206) =62.68, p=.00) with Black/White couples, at 45.7%. The study presents multiple correlation tables. Additionally, limitations of the study are discussed and suggestions for further studies are presented
