A voyage of discovery or a fast track to success: Men, Women and the MBA

This paper presents and discusses results of a research project on the personal and career benefits of the MBA. These results suggest women value the experience of doing the course and that this gives them greater >intrinsic= benefits of enhanced confidence and self worth. Men gain greater >extrinsic= benefits of enhanced pay and status and place a greater emphasis on the credential value of the MBA. However, the MBA has less of a transforming effect on how they see themselves and their organisations

Evaluation and improvement of economic efficiency in the sphere of bore-hole drilling methods

One of the important requirements for the methods and technologies, especially in the extractive industry, is cost-effective use of resources. The amount of exploration and industrial bore-hole drilling for various purposes is increasing in today’s world. Since drilling is the main type of exploration, it is necessary to improve the technology and to reduce costs. The article discusses an alternative to the existing method of bore-hole drilling developed in Tomsk Polytechnic University on the basis of the discovery made by scientists of the University. Electric pulse drilling technology is an innovation with the estimated base of evidence. The technique consists of rock breaking without drilling in it. This technology is fundamentally different from the existing ones; therefore, its application requires modification and updating of all operation systems. High barriers to entry and introduction to the industry are specific to electric pulse drilling. The authors concluded that the technology of electric pulse drilling provides an alternative of production methods and tools, which allows finding the best option to reduce costs and thereby to increase resource efficiency of production or project

Principles for the selection and integration of educational multimedia materials

This paper sets out to clarify the decision framework for the selection and integration of educational multimedia material into courses. Two main areas are discussed. The first involves matching the educational principles inherent in the multimedia artefact to the aims of the course. The opposition between instructionist and constructivist approaches is particularly highlighted. The second area concerns the models used to integrate the multimedia component into the overall course. The models are classified in terms of how they distribute the balance of responsibility for explicit educational structuring between the multimedia system and the course tutor. The paper does not set out prescriptive rules; it aims rather to inform and articulate the decision space for the tutor

New Electricity Technologies for a Sustainable Future

There is a growing concern over our reliance on conventional electricity sources and their long-term environmental, climate change, and security of supply implications, and much hope is vested in the ability of future technological progress to tackle these issues. However, informed academic analysis and policy debates on the future of electricity systems must be based on the current state, and prospects of, technological options. This paper is the introductory chapter in the forthcoming book Future Electricity Technologies and Systems. The book comprises contributions from leading experts in their respective technology areas. The chapters present state of the art and likely progress paths of conventional and new electricity generation, networks, storage, and end-use technologies. In this paper we review the growth trend in electricity demand and carbon emissions. We then present a concise overview of the chapters. Finally, we discuss the main contextual factors that influence long-term technological progress

Lattice Gauge Theories at the Energy Frontier

This White Paper has been prepared as a planning document for the Division of High Energy Physics of the U. S. Department of Energy. Recent progress in lattice-based studies of physics beyond the standard model is summarized, and major current goals of USQCD research in this area are presented. Challenges and opportunities associated with the recently discovered 126 GeV Higgs-like particle are highlighted. Computational resources needed for reaching important goals are described. The document was finalized on February 11, 2013 with references that are not aimed to be complete, or account for an accurate historical record of the field.Comment: Submitted for the Snowmass 2013 e-Proceedings with 44 pages, 10 figures, and 3 table

Resource management for Sustainable Development of Island Economies

What is the role of resource management in sustaining competitiveness for island economies such as the Republic of the Philippines and Hawaii? We review the history of thought on sustainable resource management and sustainable development and then turn to the threats to sustainability from the resource curse and the parallel curse of paradise. We show how the resource curse undermines the pursuit of sustainability and describe innovations in governance that can transform the curse into a blessing.Resource curse, sustainable development, Dutch disease

Anisotropic shock sensitivity for β-octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine energetic material under compressive-shear loading from ReaxFF-ℓg reactive dynamics simulations

We report here the predictions on anisotropy of shock sensitivity and of chemical process initiation in single crystal β-octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (β-HMX) using compressive shear reactive dynamics (CS-RD) model with ReaxFF-ℓg reactive force field. Analysis of resolved shear stress induced by uniaxial compression along three shock directions normal to (110), (011), and (010) planes leads to identify eight slip systems as candidates for shear deformation. For each of the eight slip systems, non-equilibrium reactive dynamics simulations were carried out to determine thermal, mechanical, and chemical responses to shear deformation. Shock direction normal to (010) plane exhibits large shear stress barriers arising from steric hindrance between molecules of adjacent layers leading to local dramatic energy and temperature increases under shear flow that in turn accelerate chemical bond breaking and initial product formation processes, promoting further molecular decomposition and eventually transition to detonation. This suggests that single crystal β-HMX is sensitive to shocks in direction normal to (010) plane. Shock directions normal to (110) and (011) planes reveal significantly less steric hindrance, leading to more modest energy and temperature increases followed by slower chemical reaction initiation. Thus, shock directions normal to (110) and (011) planes are less sensitive than shock direction normal to (010) plane, which agree with interpretations from currently available plate impact experiments on HMX. This validation of CS-RD and ReaxFF for characterizing sensitivity of single crystal energetic materials indicates that these methods can be applied to study sensitivity for more complex polymer bonded explosives and solid composite propellants having complex microstructures, corrugated interfaces, as well as defects
