United States data collection activities and requirements, volume 1
The potential market for a data collection system was investigated to determine whether the user needs would be sufficient to support a satellite relay data collection system design. The activities of 107,407 data collections stations were studied to determine user needs in agriculture, climatology, environmental monitoring, forestry, geology, hydrology, meteorology, and oceanography. Descriptions of 50 distinct data collections networks are described and used to form the user data base. The computer program used to analyze the station data base is discussed, and results of the analysis are presented in maps and graphs. Information format and coding is described in the appendix

TDRSS/user satellite timing study
A timing analysis for data readout through the Tracking and Data Relay Satellite System (TDRSS) was presented. Various time tagging approaches were considered and the resulting accuracies delineated. The TDRSS was also defined and described in detail
Knee moments of anterior cruciate ligament reconstructed and control participants during normal and inclined walking
Objectives: Prior injury to the knee, particularly
anterior cruciate ligament (ACL) injury, is known to
predispose one to premature osteoarthritis (OA). The
study sought to explore if there was a biomechanical
rationale for this process by investigating changes in
external knee moments between people with a
history of ACL injury and uninjured participants
during walking: (1) on different surface inclines and
(2) at different speeds. In addition we assessed
functional differences between the groups.
Participants: 12 participants who had undergone
ACL reconstruction (ACLR) and 12 volunteers with
no history of knee trauma or injury were recruited
into this study. Peak knee flexion and adduction
moments were assessed during flat (normal and
slow speed), uphill and downhill walking using an
inclined walkway with an embedded Kistler Force
plate, and a ten-camera Vicon motion capture
system. Knee injury and Osteoarthritis Outcome
Score (KOOS) was used to assess function.
Multivariate analysis of variance (MANOVA) was
used to examine statistical differences in gait and
KOOS outcomes.
Results: No significant difference was observed in
the peak knee adduction moment between ACLR and
control participants, however, in further analysis,
MANOVA revealed that ACLR participants with an
additional meniscal tear or collateral ligament
damage (7 participants) had a significantly higher
adduction moment (0.33±0.12 Nm/kg m) when
compared with those with isolated ACLR
(5 participants, 0.1±0.057 Nm/kg m) during gait at
their normal speed ( p<0.05). A similar (nonsignificant)
trend was seen during slow, uphill and
downhill gait.
Conclusions: Participants with an isolated ACLR
had a reduced adductor moment rather an increased
moment, thus questioning prior theories on OA
development. In contrast, those participants who
had sustained associated trauma to other key knee
structures were observed to have an increased
adduction moment. Additional injury concurrent
with an ACL rupture may lead to a higher
predisposition to osteoarthritis than isolated ACL
deficiency alone
Attribution of pollution generation to local private and public demands in a small open economy: results from a SAM-based neo-classical linear attribution system for Scotland
For the construction of environmental accounts, Input Output (IO) systems have a number of clear advantages. First IO is an internally consistency, rigorous accounting framework. Second, the characteristics of IO systems are well known. Third, IO systems focus on the link between intermediate and final demands, and can attribute the indirect, intermediate use of commodities to elements of final demand. However, there are concerns over the degree of appropriateness of the standard IO attribution approaches (McGregor et al, 2001a). If standard Type I output-pollution multiplier, especially in the case of a very open economy such as Scotland, responsibility for much pollution can be attributed to external sources of demand. Furthermore, when Type II output-pollution multipliers are utilised, local private consumption virtually disappears as a pollution source. This seems to be at variance with the common environmental approach, which would wish to place domestic consumption at the centre of pollution attribution
The national impact of regional policy : policy simulation with labour market constraints in a two-regional computable general equilibrium model
The first step in a comprehensive evaluation of regional policy is to identify its full spatial impact. This involves two tasks. The first is to determine the form and strength of inter-regional linkages. The second is to specify the national constraints within which the system of regional economies operates. In this paper we use simulation results from a two-region Computable General Equilibrium (CGE) model of Scotland and the rest of the UK (RUK) to investigate these issues. The inter-regional linkages incorporate trade and income flows, inter-regional capital mobility and migration. The constraint that we focus on is an overall national population constraint and its impact on regional wage determination. The paper is structured in the following way. Section 2 outlines the AMOSRUK modelling framework. Section 3 describes the alternative labour-market model configurations used in the simulations. Section 4 reports the results for the model simulation and Section 5 is a short conclusion
