The research crisis in American institutions of complementary and integrative health: one proposed solution for chiropractic profession.
A crisis confronts the Complementary and Integrative Health (CIH) teaching institutions in the US. Research infrastructure is needed to build and sustain productive research programs and retain their own research faculty. In most health professions, this infrastructure is largely built through research grants. In CIH, most educational institutions are funded through student tuition, which has historically also had to be the source for building their research programs. Only a limited number of these institutions have emerged as National Institute of Health (NIH) grant-funded programs. As a result, the American chiropractic institutions have seen a retrenchment in the number of active research programs. In addition, although research training programs e.g., NIH's K awards are available for CIH researchers, these programs generally result in these researchers leaving their institutions and depriving future CIH practitioners of the benefit of being trained in a culture of research. One proposed solution is to leverage the substantial research infrastructure and long history of collaboration available at the RAND Corporation (https://www.rand.org) This article presents the proposed five components of the RAND Center for Collaborative CIH Research and the steps required to bring it to being: 1) the CIH Research Network - an online resource and collaborative site for CIH researchers; 2) the CIH Research Advisory Board - the governing body for the Center selected by its members; 3) the RAND CIH Interest Group - a group of RAND researchers with an interest in and who could provide support to CIH research; 4) CIH Researcher Training - access to existing RAND research training as well as the potential for the Center to provide a research training home for those with training grants; and 5) CIH RAND Partnership for Research - a mentorship program to support successful CIH research. By necessity the first step in the Center's creation would be a meeting between the heads of interested CIH institutions to work out the details and to obtain buy-in. The future success of CIH-directed research on CIH will require a pooling of talent and resources across institutions; something that the American chiropractic institutions have not yet been able to achieve. This article discusses one possible solution
Hypersonic Research Vehicle (HRV) real-time flight test support feasibility and requirements study. Part 2: Remote computation support for flight systems functions
The requirements are assessed for the use of remote computation to support HRV flight testing. First, remote computational requirements were developed to support functions that will eventually be performed onboard operational vehicles of this type. These functions which either cannot be performed onboard in the time frame of initial HRV flight test programs because the technology of airborne computers will not be sufficiently advanced to support the computational loads required, or it is not desirable to perform the functions onboard in the flight test program for other reasons. Second, remote computational support either required or highly desirable to conduct flight testing itself was addressed. The use is proposed of an Automated Flight Management System which is described in conceptual detail. Third, autonomous operations is discussed and finally, unmanned operations
The generic task toolset: High level languages for the construction of planning and problem solving systems
The current generation of languages for the construction of knowledge-based systems as being at too low a level of abstraction is criticized, and the need for higher level languages for building problem solving systems is advanced. A notion of generic information processing tasks in knowledge-based problem solving is introduced. A toolset which can be used to build expert systems in a way that enhances intelligibility and productivity in knowledge acquistion and system construction is described. The power of these ideas is illustrated by paying special attention to a high level language called DSPL. A description is given of how it was used in the construction of a system called MPA, which assists with planning in the domain of offensive counter air missions

The impact of trade liberalisation on South African agricultural productivity
This study attempts to examine the empirical relationship between trade and total factor productivity (TFP) in the agricultural sector using both cross -sectiona, (across nine agricultural commodities), and time -series analysis. The Error Correction Model of ordinary least square (OLS) results from the cross -sectional analysis confirm that export shares and capital formation were found to be positive and significant; whereas, import shares and real exchange rate were found to be related negatively. However, the net effect of export and import shares had a positive effect. This implies that trade liberalisation causes productivity gains. Moreover, the time -series analysis goes in the same direction as the cross -sectional results, showing that there is a robust relationship among TFP, degree of openness, and capital formation. Whereas, debt was found to be inversely related, this implies that agricultural industries / farmers lack debt management skills.TFP, OLS, Trade liberalization or degree of openness, capital formation, International Relations/Trade,
Water markets an alternative for central water allocation?
South Africa is entering a whole new era in water management. In the face of efforts to curtail runaway government spending and protect the environment, water institutions must foster the conservation and efficient allocation of existing supplies. They must also take water's growing recreational and environmental value into account. The crucial question is, can the current water institutions meet today's requirements? Despite the resulting inefficiency and waste, traditional resource economists continue to identify taxes, regulations, subsidies, and governmental allocation as solutions to today's water problems. Internationally, there is enough evidence to prove that central allocation with almost any resource gave rise to gross inefficiency. The main reason is the distortions on the value placed on resources within such a centralised planning environment. Resources are either valued to high or to low. What is the value of freshwater and how can water be allocated in such a way as to reflect the scarcity value of water? A non-linear spatial equilibrium model was developed to simulate the impact of a potential water market in the Upper-Berg River: Western Cape. This paper explores water markets as an alternative to central water allocation decisionsResource /Energy Economics and Policy,
