Lift distribution in a rectangular jet

Computer programs predict effect of slipstream-wing flow interaction on aerodynamic characteristics of deflected slipstream and tilt aircraft. One program calculates lift distribution, lift, and drag of wing in wide slipstream. Results permit development of simplified lifting surface theory for circular jet

Leadership: professional communities of leadership practice in post-compulsory education

Summary: This is a paper that reviews and outlines the academic basis behind leadership in the post-compulsory setting. Description: Leadership has been for some years a key area of strategic and operational importance in the UK post-compulsory sector - this publication aims to addresss some of the issues surrounding this topic. It discusses theories and definitions of leadership, leader professionalism and post-compulsory education. A collaborative model of professional leadership is recommended, informed by authentic, democratic dialogue with practitioners. Coalitions that foster professional networking and collaborative leadership can be creatively developed through the establishment of intentionally designed communities of leadership practice. The CAMEL (Collaborative Approaches to the Management of e-Learning) JISC infoNet HEFCE/LGM-funded model for communities of practice is discussed as one model which provides a useful template for the development of shared knowledge through professional communities of practice in collaborative leadership. It is argued that this provides a helpful way of enabling and supporting leaders to advance their understanding and ‘know how' in leadership practices in a sector currently facing significant challenges from demanding external targets and continuous monitoring in an ‘audit culture’. The publication also and gives examples of good practice and many references and links for information

The eLIDA CAMEL: designed for learning by community

This article, invited by the ALT Editor for the international ALT-N newsletter, reports on the work of the eLIDA CAMEL JISC-funded Design for Learning (D4L) competitively selected e-learning project. A Design for Learning project that grows an intentional e-learning community of practice (CoP) in Higher and Further Education (HE and FE) can stimulate challenging, illuminative processes to foster shared understandings about learning technology innovations, promoting authentic dialogue between practitioners. Technological and social insights gradually emerge in a designed CoP, symbolised by camels riding across the desert to meet together in the oases of partner hosts. Honest peer-group exchanges, facilitated by a critical friend, improve professional e-learning practice

Review of the genus Microchilus Blanchard (Coleoptera: Scarabaeidae: Rutelinae: Geniatini)

The Brazilian scarab beetle genus Microchilus Blanchard (Rutelinae: Geniatini) is reviewed. Based on examination of type specimens, Microchilus beckeri Martínez is transferred to the genus Leucothyreus becoming L. beckeri (Martínez), new combination; Leucothyreus bucki Machatschke is a new junior synonym of L. beckeri (Martínez).Microchilus is limited to two species, M. beckeri (Martínez) and a new species,Microchilus rodmani Jameson, here described. Characters that circumscribe the genus, biology, and species distribution are discussed. A key to the species is provided

A note on scalable frames

We study the problem of determining whether a given frame is scalable, and when it is, understanding the set of all possible scalings. We show that for most frames this is a relatively simple task in that the frame is either not scalable or is scalable in a unique way, and to find this scaling we just have to solve a linear system. We also provide some insight into the set of all scalings when there is not a unique scaling. In particular, we show that this set is a convex polytope whose vertices correspond to minimal scalings
