This paper focuses on the critical role of institutional entrepreneurs’ social skills in enabling transformative change as described by Multi-Level Perspective. Understanding is crucial for developing a micro-foundational view sustainability transitions. We develop an analytical framework using multiple case study Swiss cantonal planners who acted entrepreneurs during comparable transitions int...

The ability to move between air and water with miniature robots would allow distributed water sampling and monitoring of a variety of unstructured marine environments, such as coral reefs and coastal areas. To enable such applications, we are developing a new class of aerial-aquatic robots, called Aquatic Micro Aerial Vehicles (AquaMAVs), capable of diving into the water and returning to flight...

Vertical Take-Off and Landing (VTOL) vehicles is a special class of Unmanned Aerial Vehicles (UAVs). This paper summarizes the current stage of VTOL design and market, and discusses VTOL growth and technical performance comparison. A database is presented to provide information concerning VTOL technical characteristics (maximum speed, payload, range, endurance, propulsion configurations), and V...

Electronic bid documents are available from a variety of sources. Historically, contractors have printed the electronic documents and then performed their takeoffs. Takeoff viewers are now available that allow the contractor to perform their takeoffs directly from the electronic documents. Several software companies that produce takeoff viewers are listed and features of takeoff viewers are des...

Prior studies at Purdue University have shown that PTO entanglements occur most frequently on portable grain augers. A research project was conducted to measure operator exposure to PTO components and document work patterns during the use of grain augers. Information on the methodologies used to measure operator exposure is presented along with data on exposure to conventional grain augers whil...

We have solved a long-standing and seemingly paradoxical set of questions that relate to the conditions which govern spider ballooning. We show that observations of spider ballooning excursions are best explained by meteorological conditions which maximize dispersal. Dispersal is predicted to be most effective in terms of distance when the stability of the atmosphere is non-ideally convective a...

Cruickshank and Collins [2] ‘Advancing Leadership in Sport: Time to Take Off the Blinkers?’ has created something of a furore around the effectiveness and suitability of dark leadership traits and behaviours. This paper attempts to clarify some of the conceptual issues discussed within their paper, while also redressing a number of literary misrepresentations. Finally, the potential limitations...

Anurans use a saltatorial (jumping) mode of locomotion. A jumping cycle can be divided into four subphases: propulsion, flight, landing and recovery. We studied the landing phase during locomotion in Rana esculenta by measuring the ground reaction forces during propulsion and landing over a range of distances. Landing performance affects locomotor ability in jumping frogs. Landing and recovery ...

O ne vital goal of cancer research is a test that profiles individual tumors at the molecular level in order to guide treatment. Some single-marker predictive tests are now standard, as are two well-validated genomic prognostic tests for breast cancer. But for most tumors, such personalized tests are still viewed as futuristic. At a recent cancer molecular diagnostics conference, many genomic t...
