Perceptions of healthy eating and physical activity in an ethnically diverse sample of young children and their parents: the DEAL prevention of obesity study

Background: Ethnicity is a consistent correlate of obesity; however, little is known about the perceptions and beliefs that may influence engagement with obesity prevention programmes among ethnic minority children. Barriers to (and facilitators of) healthy lifestyles were examined in the qualitative arm of the London (UK) DiEt and Active Living (DEAL) study. Methods: Children aged 8–13 years and their parents, from diverse ethnic groups, were recruited through schools and through places of worship. Thirteen focus group sessions were held with 70 children (n = 39 girls) and eight focus groups and five interviews with 43 parents (n = 34 mothers). Results: Across ethnic groups, dislike of school meals, lack of knowledge of physical activity guidelines for children and negativity towards physical education at school among girls, potentially hindered healthy living. Issues relating to families' wider neighbourhoods (e.g. fast food outlets; lack of safety) illustrated child and parental concerns that environments could thwart intentions for healthy eating and activity. By contrast, there was general awareness of key dietary messages and an emphasis on dietary variety and balance. For ethnic minorities, places of worship were key focal points for social support. Discourse around the retention of traditional practices, family roles and responsibilities, and religion highlighted both potential facilitators (e.g. the importance of family meals) and barriers (reliance on convenience stores for traditional foods). Socio-economic circumstances intersected with key themes, within and between ethnic groups. Conclusions: Several barriers to (and facilitators of) healthy lifestyles were common across ethnic groups. Diversity of cultural frameworks not only were more nuanced, but also shaped lifestyles for minority children.</p

Confronting Ageing as a Caribbean Reality

This article acknowledges the increased life expectancy which Caribbean populations presently experience. It draws upon data collected throughout the region and identifies some of the main concerns which families, communities and governments need to address, in order to ensure that the elderly will not be severely disadvantaged as a consequence of their increased life expectancy. The article recommends closer cooperation between governmental agencies and non-government organizations (NGOs) in determining the needs of the elderly, as well as the provision of services for them

Best Practice Social Media Policy: Comparison of Organizational Use of Social Media Policy

Social media is a phenomenon that businesses are using to communicate with both internal and external stakeholders. The new communication channel is different from the traditional channels used by marketing, public relations, and human resources because of user created content, social dynamics, and frequent changes to the autonomous online platforms\u27 structure and social make-up. Social media websites like YouTube, Facebook and Twitter have received significant attention from both scholars and practitioners seeking best practice for organizational engagement with the phenomenon. Much of the information published for businesses, communities, and activists, who are looking into social media engagement provides consistent instruction, but are the recommended practices reflected in the practice of organizations? This thesis investigates the language used by organizations to manage use of social media in order to learn how closely they follow published advice. An analysis of the content presented in 25 organizational social media policy documents from sources spanning five industries is used to explore how corporations are approaching the use of social media. The findings reveal which practices are uniformly included in policy, and which practices are unique to the industrial focus or identity of particular organizations

Temporal and spatial variations in maximum river discharge from a new Russian data set

Floods cause more damage in Russia than any other natural disaster, and future climate model projections suggest that the frequency and magnitude of extreme hydrological events will increase in Russia with climate change. Here we analyze daily discharge records from a new data set of 139 Russian gauges in the Eurasian Arctic drainage basin with watershed areas from 16.1 to 50,000 km2 for signs of change in maximum river discharge. Several hypotheses about changes in maximum daily discharge and their linking with trends in precipitation over the cold season were tested. For the magnitude of maximum daily discharge we found relatively equal numbers of significant positive and negative trends across the Russian Arctic drainage basin, which draws into question the hypothesis of an increasing risk of extreme floods. We observed a significant shift to earlier spring discharge, which is consistent with documented changes in snowmelt and freeze‐thaw dates. Spatial analysis of changes in maximum discharge and cold season precipitation revealed consistency across most of the domain, the exception being the Lena basin. Trends in maximum discharge of the small‐ to medium‐sized rivers were generally consistent with aggregated signals found for the downstream gauges of the six largest Russian rivers. Although we observe regional changes in maximum discharge across the Russian Arctic drainage basin, no evidence of widespread trends in extreme discharge can be assumed from our analysis

Ultraviolet absorption: Experiment MA-059

A technique devised to permit the measurement of atmospheric species concentrations is described. This technique involves the application of atomic absorption spectroscopy and the quantitative observation of resonance fluorescence in which atomic or molecular species scatter resonance radiation from a light source into a detector. A beam of atomic oxygen and atomic nitrogen resonance radiation, strong unabsorbable oxygen and nitrogen radiation, and visual radiation was sent from Apollo to Soyuz. The density of atomic oxygen and atomic nitrogen between the two spacecraft was measured by observing the amount of resonance radiation absorbed when the line joining Apollo and Soyuz was perpendicular to their velocity with respect to the ambient atmosphere. Results of postflight analysis of the resonance fluorescence data are discussed

Exit plane H2O concentration measurements correlated with OH PLIF near-injector mixing measurements for scramjet flows

Mixing and combusting high enthalpy flows, similar to those encountered in scramjet engines, were investigated using a shock tunnel to produce the flow in conjunction with non-intrusive optical diagnostics which monitored the performance of two injector configurations. The shock tunnel is configured to produce Mach 3 flow and stagnation enthalpies corresponding to flight equivalent Mach numbers between 7 and 11. A pulsed hydrogen injection capability and interchangeable injector blocks provide a means of examining high speed, high enthalpy reacting flows. Planar laser induced fluorescence (PLIF) of OH molecules in the near injector region produced images which show the combusting and mixing zones for the reacting flow. Line-of-sight exit plane measurement of water concentration and temperature were used to provide a unique method of monitoring exit plane products. These results demonstrated that a velocity matched axial injection system produced a fuel jet that lifted off the floor of the duct. Mixing was observed to increase for this system as a velocity mismatch was introduced. Comparison of exit plane water concentrations for a wall jet injection system and a velocity matched injection system indicated similar mixing performance but an accurate pressure measurement is necessary to further validate the result. In addition, exit plane measurements indicated an approximate steady-state condition was achieved during the 1 to 2 ms test times

A review of climate change impacts on urban soil functions with examples and policy insights from England, UK

As of 2010, more than half of the global population resides in urban areas and relies to some extent on the functions, services and natural capital provided by urban soils. Greater extremes in climate predicted for the coming decades will impact on these urban soil functions to varying degrees. We provide an inventory of urban soil functions based on an extension to the typology of the Millennium Ecosystem Assessment (i.e. we added a carrying function to those of supporting, regulating, provisioning and cultural) and review the climate drivers which are likely to have the most significant impacts upon them, using urban soils of England as an exemplar. We identify knowledge gaps, in areas such as carbon cycling and storage, disease regulation and cultural services. We assess adaptation measures which may ameliorate these potential, climate change-related impacts including changes in construction practices, developments in green architecture and development proposals under the planning regime. We discuss the lack of policies relating to urban soils and the problem associated with monitoring their functions, as is often the case, when large quantities of soil are removed and replaced leading to major transformation of soil properties which may be un-related to pedogenic processes

A Comprehensive Analysis of Aquatic Programming at Historically Black Colleges and Universities (HBCUs)

This article provides a comprehensive examination of aquatic programming at Historically Black Colleges and Universities (HBCUs). HBCUs consist of public, private, 2-year, and 4-year institutions (U.S. Department of Education, 2018). Historically, HBCUs provided descendants of the enslaved access to higher education opportunities (Brown, Donahoo, & Bertrand, 2001). HBCUs now serve a more diverse community and the core focus remains on inclusion, social justice, diversity, empowerment, leadership, and cultural competence (Kennedy, 2012; Rawlins, 2018). Consequently, HBCUs may provide an ideal environment to address aquatic activity and the drowning disparity in the African American community. In the current study, researchers sent a survey to 102 HBCUs to better assess the prevalence of aquatics programming at these institutions. Approximately 38 percent of the HBCUs responded to the survey. The results of this study indicate that there is inconsistent institutional knowledge about competitive and non-competitive swimming programs from the past to the present. However, 31 percent of participants reported offering swim classes to members of the campus community. Additionally, 51 percent of participants reported offering swim courses for college credit. Most importantly, 49 percent of participants indicated a desire to build or expand aquatics programming. The drowning disparity is a result of a cycle that includes historical barriers that denied many African Americans’ access to aquatic facilities and programming (Anderson, 2017). Identifying aquatics programming at HBCUs is a critical step to addressing the drowning disparity
