Aerodynamic Design of a Propeller for High-Altitude Balloon Trajectory Control

The aerodynamic design of a propeller for the trajectory control of a high-altitude, scientific balloon has been performed using theoretical methods developed especially for such applications. The methods are described. Optimum, nonlinear chord and twist distributions have been developed in conjunction with the design of a family of airfoils, the SE403, SE404, and SE405, for the propeller. The very low Reynolds numbers along the propeller blade fall in a range that has yet to be rigorously investigated, either experimentally or theoretically

Co-Design Apprenticeships & Future Workforce Pathways: Corporate HR & University Partnerships

Strategic Opportunity: The workforce is ever-changing. Our latest challenge is finding workers who walk in with our needed skills and knowledge. This developed workforce is scarce and expensive. With the current workforce skills gaps increasing and rapidly changing job requirements, we need to think strategically and maximize all of our learning and development programs and dollars. This roundtable will discuss using tuition assistance and apprenticeships to create leadership development programs effectively and efficiently through partnerships. We will discuss the untapped opportunities within tuition assistance programs and how to align training and tuition assistance programs to build leadership pipelines about their personal experiences and are least likely to center on experiential learning. What we will explore: Rich will kick-off this roundtable with a five minute overview of IMSA’s vision statement is “by 2022, IMSA is a recognized global leader and catalyst in equity and excellence in STEM teaching and learning, innovation and entrepreneurship.” Followed by Michelle sharing a five-minute overview of Home Depot’s partnership with Bellevue University to create leadership pathways. This discussion of practical insights will dive into questions that look at Career Development from Talent Risk perspective like: Is the recent abandoning the four-year degree as a qualification a break from hiring orthodoxy or a short-term fad? As reported in the news recently, high-paying tech outlets like Apple, Google, and IBM, in addition to service-oriented companies like Costco, Starbucks, and Chipotle. Let’s explore why so many companies still insist upon a degree in the first place. How are assessments and frameworks for critical capabilities used to identify development needs? To what extent does your organizations use early career development to attract future talent? What are the “Must Have” practices for early career development? What measures are demonstrating the impact of early career development

Retail governance and agrifood sustainability: insights and research needs

"Food security, food safety, healthy consumption habits, and environmental sustainability are essential to the well-being of societies worldwide. Yet, progress in fostering sustainability in the global agrifood system has been slow at best and significant challenges remain. First, food insecurity remains a problem for millions of people, while its range and consequences have been aggravated by the recent food crisis (FAO 2008b). Second, repeated food scandals and health scares constitute additional challenges for food governance (World Bank 2005). Food is the number one cause of premature death in the western world due to the increasing consumption of fattier, saltier, and sweeter foods and drinks (Popkin 2002). Even in many Asian countries obesogenic diets are becoming more prevalent (Florentino 2002; IOTF 2005). Third, threats to the provision of adequate amounts of nutritious food are expected to multiply as a result of climate change (European Commission 2008a). At the same time, the food sector itself is a major contributor to direct and indirect greenhouse gas emissions (FAO 2008a). Fourth, alternative food products – while promising environmental and health benefits in relation to their conventional equivalents – are also associated with costs. In India, thousands of farmers have reportedly committed suicide, partly as a result of debt due to unfair biotech deals (Nagaraj 2008).(...)" [authors remark

Does politics impact carbon emissions?

"Do political variables influence long-term environmental transitions? The discussion on the determinants of the environmental performance of countries has been dominated by a focus on the Environmental Kuznets curve. This concept concentrated primarily on the role of economic factors, in particular per capita income levels. By contrast, we outline both conceptually and empirically how political factors can affect long-term carbon trajectories. Our findings from an error-correction model suggest that political factors are an important explanatory variable for carbon emissions in over 100 countries during the period 1970-2004. The results show that political capacity reduces carbon emission in OECD countries whereas political constraints, democracy and the Kyoto Protocol reduce long-term carbon emission in the group of all countries as well as in non-OECD countries."

Barriers and Facilitators of Outcome Collection During Hand Surgery Outreach: A Quality Improvement Study.

BACKGROUND: Surgical outreach trips to low- and middle-income countries have been increasing. Outcome collection on these trips, however, has been inconsistent and often incomplete. We conducted a qualitative study of surgeons, administrators, and patients to identify the barriers and facilitators to outcome collection on hand surgery outreach trips to Hospital 175 in Ho Chi Minh City, Vietnam. METHODS: A purposive sample of surgeons, administrators, and patients from Hospital 175 were interviewed about their beliefs regarding outcome collection. We used a semi-structured interview guide based on the Theoretical Domains Framework to systematically explore barriers and facilitators. Interviews were recorded, transcribed, and analyzed using content analysis. Beliefs underlying similar responses were identified and aggregated to describe barriers and facilitators of outcome measurement. RESULTS: Twelve surgeons and administrative staff (3 visiting and 9 local) and 5 patients were interviewed before saturation was achieved. All stakeholders believed outcome collection on hand surgery outreach trips is important. Barriers identified were primarily related to environmental context and resources (eg, cost of returning) and memory, attention, and decision process (eg, difficulty in remembering patient follow-up intervals). The most commonly identified barriers address the distance patients live from the hospital/clinic, the resources required for them to return, and the lack of an organized system to assist in follow-up. CONCLUSIONS: Multiple barriers to outcome collection exist at Hospital 175 in Vietnam. Understanding these barriers informs context-specific implementation approaches to collect outcomes on hand surgery outreach trips, which may improve the safety and quality of care provided
