Video concepts in CRM training

Cockpit resource management (CRM) is discussed in the context of programs developed by Pennsylvania Airlines and Ransome Airlines. Video techniques in flight training are emphasized. Problems in cockpit interpersonal communication are addressed

The effects of design and operating variables on the response of an axial flow fan to inlet flow distortions

The results of a study of total pressure and velocity circumferential distortions in an axial-flow fan are presented. Some of the fundamental experimental data needed to understand distorted flow phenomena as affected by design and operating variables are provided. The flow through an isolated rotor was examined at various operating conditions with six different distortions and three different blade stagger angles. Circumferential surveys were conducted upstream and downstream of the rotor using five-hole probes in the nonnulling mode. The total pressure and axial velocity distortion data were analyzed to determine the degree of distortion attenuation as a function of blade stagger angle, mean incidence angle, and reduced frequency. The results indicate that, for the rotors tested, the mean incidence or loading has very little effect on the distortion attenuation

Measurement of Coherent Elastic Neutrino-Nucleus Scattering from reactor antineutrinos

The 96.4 day exposure of a 3 kg ultra-low noise germanium detector to the high flux of antineutrinos from a power nuclear reactor is described. A very strong preference ($p<1.2\times10^{-3}$) for the presence of a coherent elastic neutrino-nucleus scattering (CE$\nu$NS) component in the data is found, when compared to a background-only model. No such effect is visible in 25 days of operation during reactor outages. The best-fit CE$\nu$NS signal is in good agreement with expectations based on a recent characterization of germanium response to sub-keV nuclear recoils. Deviations of order 60\% from the Standard Model CE$\nu$NS prediction can be excluded using present data. Standing uncertainties in models of germanium quenching factor, neutrino energy spectrum, and background are examined.Comment: 6 pages, 5 figures.

Climate information to support wildlife management in the North Central United States

This paper investigates what is needed to make climate and weather information more usable for the wildlife management practitioners and ecological researchers in the Prairie Potholes Region (PPR) of the North Central United States. Using interviews, policy document analysis, and participant observation, we identify climate and weather information needs, barriers to use, and opportunities to provide better information to these users. We found that the research and management communities need guidance on how to interpret and apply existing information. Climate information needs in the PPR are driven by the need to understand how projected changes in precipitation will impact prairie wetland ecology. Primary needs include guidance towards selecting, interpreting, and using various climate information products to understand impacts and explanations of the differences between new products and previously available information. Another need includes information on how the societal responses to climate change will further impact ecological systems. Existing management priorities, limited institutional resources, and limited ecological data are remaining barriers that can be ameliorated by leveraging existing policy processes or trusted sources of information to provide guidance, thereby reducing time and costs associated with using climate information in wildlife policy planning. Throughout, we emphasize the importance of the social and ecological aspects of the decision-making context to shape climate information needs, barriers, and entry points. Additional research is needed on the diverse ways that users engage with and use climate information, and additional efforts are needed to co-produce guidance documents that interpret climate information for management and research communities.</p

An exploration of personal benefits reported by students of a health and wellness coach training programme

This study explores the ‘personal benefits’ of training reported by graduates of a health and wellness coach training programme. In particular, we investigated reported benefits, areas of life affected by the training, and whether changes occurred in health and wellness or more broadly. Using a semi-structured interview design, we incorporated an atheoretical qualitative approach to data collection and analysis. Thematic analysis was used at a semantic level to identify the major themes. The findings indicate a blend of personal and professional benefits for the graduate. As a result of participation in the programme, graduates gained greater self-knowledge, and better connection with others. They also improved their professional optimism and noted positive changes in personal health and wellbeing. Further research is needed to see if trainees from other health and wellness coach training programmes report similar personal benefits, and to identify key training elements instrumental to generating these benefits
