Using an instrumented manikin for Space Station Freedom analysis

One of the most intriguing and complex areas of current computer graphics research is animating human figures to behave in a realistic manner. Believable, accurate human models are desirable for many everyday uses including industrial and architectural design, medical applications, and human factors evaluations. For zero-gravity (0-g) spacecraft design and mission planning scenarios, they are particularly valuable since 0-g conditions are difficult to simulate in a one-gravity Earth environment. At NASA/JSC, an in-house human modeling package called PLAID is currently being used to produce animations for human factors evaluation of Space Station Freedom design issues. Presented here is an introductory background discussion of problems encountered in existing techniques for animating human models and how an instrumented manikin can help improve the realism of these models

“Blurred boundaries”: When nurses and midwives give anti-vaccination advice on Facebook

© The Author(s) 2022. This is the accepted manuscript version of an article which has been published in final form at https://doi.org/10.1177/09697330211041749Background: Nurses and midwives have a professional obligation to promote health and prevent disease, and therefore they have an essential role to play in vaccination. Despite this, some nurses and midwives have been found to take an anti-vaccination stance and promulgate misinformation about vaccines, often using Facebook as a platform to do so. Research question: This article reports on one component and dataset from a larger study – ‘the positives, perils and pitfalls of Facebook for nurses’. It explores the specific issue of nurses and midwives who take an anti-vaccination stance, deemed to be unprofessional by crossing professional boundaries and by providing medical information on Facebook that is not within their scope of practice. Participants: Data were collected via an online worldwide survey from nurse and midwife participants, distributed and ‘snowballed’ through relevant nursing and midwifery groups on Facebook. In total, 1644 Registered Nurses and Midwives, and Enrolled Nurses worldwide attempted the online survey. There were 1100 (66.9%) completed surveys and 54 partially (33.1%) completed surveys. Semi-structured interviews were also conducted online using Skype® with 17 participants in Australia. Ethical considerations: Ethical processes and procedures have been adhered to relating to privacy, confidentiality and anonymity of the participants. Findings/results: A mixed-methods approach was used, including descriptive and content analysis of the quantitative survey data and thematic analysis of the qualitative interview data. The main theme ‘blurred boundaries’ was generated, which comprised three sub-themes: ‘follow the science, ‘abuse of power and erosion of trust’ and ‘the moral and ethical responsibility to safeguard public health’. The results offer an important and unique understanding of how nurses and midwives interpret the conduct of fellow health professionals as unprofessional and crossing the professional boundary if they used Facebook to promulgate anti-vaccination messages and/or give medical advice online. Conclusion: There are many positives and negatives for nurses and midwives associated with using Facebook for personal and professional communication, which is in keeping with the results of the larger study from which this article is taken. Professional behaviour is a key theme in the larger research as is the ethical construct of ‘every act has a consequence’; however, in this article, the theme ‘blurred boundaries’ offers an overall understanding of how nurses and midwives interpret the behaviour of their colleagues who espouse anti-vaccination sentiment and/or give medical advice online that is outside their scope of practice and education.Peer reviewe

Leveraging firm-level marketing capabilities with marketing employee development ☆

Resource-based view of the firm Complementarities Employee development Customer satisfaction Performance Using the theoretical foundations of the resource-based view of the firm, this study develops and measures marketing employee development capabilities and investigates how it moderates the relationships between brand and customer relationship management capabilities and firm performance outcomes. Based on a random sample survey of chief marketing executives from selected industries, combined with objective firm performance indicators and controls, results demonstrate that marketing employee development capabilities can leverage the relationships between firm-level marketing capabilities and customer satisfaction, market effectiveness, and objective financial performance. Further, these results show that such capabilities can be complementary and, in some cases, even substitute for each other, which improves organizational performance. Implications for researchers and marketing managers are discussed

Design and Experimental Performance of a Two Stage Partial Admission Turbine, Task B.1/B.4

A three-inch mean diameter, two-stage turbine with partial admission in each stage was experimentally investigated over a range of admissions and angular orientations of admission arcs. Three configurations were tested in which first stage admission varied from 37.4 percent (10 of 29 passages open, 5 per side) to 6.9 percent (2 open, 1 per side). Corresponding second stage admissions were 45.2 percent (14 of 31 passages open, 7 per side) and 12.9 percent (4 open, 2 per side). Angular positions of the second stage admission arcs with respect to the first stage varied over a range of 70 degrees. Design and off-design efficiency and flow characteristics for the three configurations are presented. The results indicated that peak efficiency and the corresponding isentropic velocity ratio decreased as the arcs of admission were decreased. Both efficiency and flow characteristics were sensitive to the second stage nozzle orientation angles

Regulating mobility in the Peruvian Andes: road safety, social hierarchies and governmentality in Cusco's rural provinces

Significant developments in road safety regulation have taken place in Peru during recent years, reflecting international efforts to reduce worldwide fatalities and injuries. A series of measures has sought to bring about transformations in governmentality among passengers on public transport. Seen ethnographically, these have had uneven success on the ground. In rural provinces of Cusco, situated histories and sociologies of mobility have sometimes led to ambivalence, unobtrusive resistance or reinforcement of discriminatory attitudes. This article explores how reception of the regulations has been refracted through class, ethnic and geographical divisions within Peruvian society, and argues for both the applied and theoretical utility of anthropological study of road safety governance
