Synergism of He-3 acquisition with lunar base evolution

It is shown how acquisition of He-3 affects Lunar Base development and operation. A four phase evolutionary Lunar Base scenario is summarized with initial equipment mass and resupply requirements. Requirements for various He-3 mining operations are shown and available by-products are identified. Impacts of mining He-3 on Lunar Base development include increases in equipment masses to be delivered to the lunar surface and a reduction of Lunar Base resupply based on availability of He-3 acquisition by-products. It is concluded that the acquisition of this valuable fusion fuel element greatly enhances the commercial potential of a Lunar Base

Becoming Adults: One-Year Impact Findings from the Youth Villages Transitional Living Evaluation

Young adults with histories of foster care or juvenile justice custody experience poor outcomes across a number of domains, on average, relative to their peers. While government funding for services targeting these groups of young people has increased in recent years, research on the effectiveness of such services is limited, and few of the programs that have been rigorously tested have been found to improve outcomes. The Youth Villages Transitional Living Evaluation is testing whether the Transitional Living program, operated by the social service organization Youth Villages, makes a difference in the lives of young people with histories of foster care or juvenile justice custody. The program, which was renamed "YVLifeSet" in April 2015, is intended to help these young people make a successful transition to adulthood by providing intensive, individualized, and clinically focused case management, support, and counseling

Xtending Likages Between Organizational Analysis and Social Structure: A Case Study of the Celebrity-Construction of a Chinese Marketplace

This paper examines the emergence of firm-celebrity, both an intangible-asset, and a facilitator of competitive advantage. Institutional approaches have asserted that organizations from the same organizational field and characterized by comparable structural positions face similar structural forces. These result in isomorphic tendencies, and similarities among firms. But, in any organizational field, differences among firms also exist. Apart from research on variations resulting from intra-organization factors, however, firm-differentiating processes have not received much attention. This paper focuses on various firm-external social constructions: legitimacy, reputation, and status, and how they impact the emergence of firm-celebrity, a construct that helps to differentiate one firm from another. The paper adopts a historical, relationally framed approach, which features a firm-celebrity case study.http://deepblue.lib.umich.edu/bitstream/2027.42/64358/1/wp967.pd

Research and Design of Supportive Exoskeletal Aides for the Physically ChallengedAn Initial Investigation Into The Fundamentals And Rudiments Of Building A Full Body ExoskeletonMark

The purpose of this study is to provide methodology for designing exoskeletal prostheses targeted to specific pathologies associated with: Cerebral Palsy; Limb Deficiency; Spinal Pathologies; and Functional Limb Pathologies This study will extend to whole body exoskeletal structures. The project will be performed in conjunction with Shriner’s Hospital for Children in Springfield, Massachusetts; M.I.T. Bio-prosthetic Group; and finally, Massachusetts General Hospital Orthopedics Group. Further work will be done designing the necessary components for the project in Solidworks utilizing a 3D mannequin. The parts will then be fabricated using a CNC machine, first making them from foam insulation, then from wood and finally from aluminum

Measuring Synchronicity and Co-movement of Business Cycles with an Application to the Euro Area

We develop multivariate measures of synchronicity and co-movement of business cycles. In addition to synchronicity, the co-movement measure takes differences between cycle amplitudes into account that have been overlooked in most previous studies. We apply the new measures to the euro area. Synchronicity and co-movement for the region as a whole do not exhibit a clear upward tendency. Although several countries saw the similarity of their business cycle vis-`a-vis the euro area reference cycle increase, national business cycles remain fairly diverse. Changes in business cycle amplitudes cause most of the observed change in cycle co-movement.business cycles, synchronisation, concordance, co-movement, cycle amplitudes, euro area

Trends in health care commissioning in the English NHS: an empirical analysis

In recent years there have been marked changes in organisational structures and budgetary arrangements in the English NHS, potentially altering the relationships between purchasers (primary care organisations (PCOs) and general practices) and providers. Using data on elective hospital admissions from 1997/98 to 2002/03 we find that commissioning has become significantly more concentrated at PCO and GP level. There was a reduction in the average number of different providers used by PCOs (16.7 to 14.2), an increase in the average share of admissions accounted for by the main provider (49% to 69%), and an increase in the average Herfindahl index (0.35 to 0.55). About half the increase in concentration arose from the increase in the number of purchasing organisations from 100 to 302. The rest was due to mergers amongst providers and the abolition of fundholding. GP fundholding practices which held budgets for elective admissions had less concentrated admission patterns than non-fundholders whose admissions were paid for by their primary care organisation. There was an increase in concentration of admissions for both types of GP practice but fundholders used more providers, had smaller shares at their main provider, and had smaller Herfindahl indices.concentration, Herfindahl, purchasing, budgets, elective admissions

The Effects of Budgets on Doctors Behaviour: Evidence from a Natural Experiment

In many health care systems primary care physicians act as ‘gatekeepers’ to secondary care. We investigates the impact of the UK fundholding scheme under which general practices could elect to hold a budget to meet the costs of elective surgery for their patients. We use a differences in differences methodology on a large four year panel of English general practices before and after the abolition of fundholding. Fundholding incentives reduced fundholder elective admission rates by 3.3% and accounted for 57% of the difference between fundholder and nonfundholder elective admissions, with 43% a selection effect due to unobservable differences in practice characteristics. Fundholding had no effect on emergency admissions.budgets, health care, fundholding, admission rates

Volume and Cost Implications of Product Portfolio Complexity

Business leaders are concerned about the impacts of increasing levels of product portfolio complexity since many sense that complexity related costs such as order management, procurement, and inventory threaten to undermine operational efficiencies and consume profits. Even so, managers do not fully understand the extent and breadth of the impacts of product portfolio complexity. A more complete understanding of the operational effects of product portfolio complexity is lacking partially because researchers have not yet offered a robust theoretical perspective or studied it in a focused controlled way; until now. Herein, measures of product portfolio complexity are developed and related to sales volume and supply chain costs. Revealed are nonlinearities which imply optimal portfolio configurations and an approach to quantifying the most profitable configurations. This books is of interest to the corporate manager or consultant seeking a greater understanding of the topic and wanting to maximize organizational performance. It will also be of interest to the academic who wishes to understand theoretical underpinnings of product portfolio complexity
