The Manifest Destiny Of Education: Past, Present And Beyond The Boundaries Of Tradition

The generation currently in secondary schools has never known the world without the Internet, has spent thousands of hours each year interacting with video games and social media, and has high expectations for the degree of control and choices they will have regarding employment, entertainment, and the education they receive.The employers of our future graduates have undergone - and will continue to undergo - profound changes in consumer behavior and technology-based marketing and value creation, while simultaneously facing intense global competition, rapid technological advances, and dynamic markets. Employer demands for increasingly flexible, self-motivated, collaborative, communicative, creative, energetic, technology savvy employees will continue to rise. These conditions are fundamentally changing consumer and employer expectations of education and driving the need for ever greater relevance, personalization, flexibility, mobility, and meaningful and relevant outcomes. In many respects, we must work toward and plan for an evolving target and, as such, we should work to create dynamic contexts as well as learning what can change and be modified as needed

Ab initio study of electronic and magnetic structure and structural phase transition of (Fe 1-xMn x) 2P 1-yGe y alloys

The paper presents results of the ab initio electronic structure calculations performed for the (Fe0:5Mn0:5)2P0:67Ge0:33 alloy, a member of (Fe1xMnx)2P1yGey family of alloys showing a giant magnetocaloric e ffect. Calculations con rmed the strong relationship between the magnetic state and crystal structure of the alloy. To investigate the isostructural phase transition driven by external magnetic eld observed in (Fe0:9Mn1:1)P0:8Ge0:2 we utilized the xed spin moment approach. Total energy analysis con rmed the occurrence of isostructural phase transition

Exploring modularity in biological networks

Network theoretical approaches have shaped our understanding of many different kinds of biological modularity. This essay makes the case that to capture these contributions, it is useful to think about the role of network models in exploratory research. The overall point is that it is possible to provide a systematic analysis of the exploratory functions of network models in bioscientific research. Using two examples from molecular and developmental biology, I argue that often the same modelling approach can perform one or more exploratory functions, such as introducing new directions of research, offering a complementary set of concepts, methods and algorithms for individuating important features of natural phenomena, generating proofs of principle demonstrations and potential explanations for phenomena of interest and enlarging the scope of certain research agendas. This article is part of the theme issue 'Unifying the essential concepts of biological networks: biological insights and philosophical foundations'

The Defense Life Cycle Management System As A Working Model For Academic Application

Performing the review and assessment of masters’ level degree programs can be an overwhelming and challenging endeavor.  Getting organized and mapping out the entire review and assessment process can be extremely helpful and more importantly provide a path for successfully accomplishing the review and assessment of the entire program.  This paper will provide a roadmap that was used as a guide for accomplishing a successful review and assessment of academic degree programs in a logical and succinct manner by adapting a proven model originally developed for the acquisition and life cycle management of new equipment, materials, and systems. This paper will also discuss how the Integrated Defense Acquisition, Technology, and Logistics Life Cycle Management System process was adapted to the needs of an academic institution of higher-learning

First detection of a highly invasive freshwater amphipod (Crangonyx floridanus) in the United Kingdom

The freshwater gammarid, Crangonyx floridanus, originates from North America but has invaded and subsequently spread rapidly throughout Japan. We provide here the first genetic and microscopic evidence that C. floridanus has now also reached the United Kingdom. We found this species in two locations separated by more than 200 km (Lake Windermere in the North of the UK and Smestow Brook, West Midlands). The current distribution of C. floridanus is currently unknown, however, both sites are well connected to other river and canal systems. Therefore, the chance of further spread is high. Genetic analyses of C. floridanus indicate that British inland waters are colonised by the same lineage, which invaded Japan. We recommend further work to assess the distribution of this species and its impact on the local fauna and flora

PROGRESS REPORT ON FRICTION LOSS OF SLURRIES IN STRAIGHT TUBES

This progress report summarizes the results obtained to date on the experimental evaluation of the loss of head entailed in pumping slurries through a straight horizontal tube. The slurries used in the investigation consisted of spherical particles of glass, steel and lead in water. The particle size and concentrations were nominally constant for a given slurry, but the various slurries tested covered the size range from 0.00122 to 0.0722 inches in diameter. Concentrations from zero to approximately 50 per cent by weight were used.</p
