Central Venous Pressure Reference Points Measured on Post-Mortem Subject
… The accurate determination of an external zero reference level corresponding with mid right atrial level would make possible reliable measurements in either position. The purpose of this study was to help determine the reliability of two central venous pressure extrathoracic reference points; …

A theory of adaptive reference points in decision-making and negotiation
Careful examination of the evidence relating to decision framing revealed a regularity not previously noted. A theory of outcome framing consistent with this finding is developed. An implication of the theory is that the formulation effect will be eroded under the types of experience available in …

Apparel clothing reference points for important shopping occasions and decision-making styles of Greek college students
… concerning how they form their consumption preferences by elaborating reference points, in order to be better informed on items for a measurement scale. In addition the current study conceptualized the categories of shopping orientations (or decision-making styles) of Greek college students, …

Identification and incorporation of quantitative indicators of ecosystem function into single-species fishery stock assessment models and the associated biological reference points
… of estimating single-species biological reference points from multispecies data and to determine the effect of fishing on other species in the same community. Three series of simulations were created to explore connectance, rebuilding plans, and multispecies fisheries in the …

Growth and Yield-Per-Recruit Modeling of Spot (<i>Leiostomus xanthurus</i>) in the Chesapeake Bay, and a Comparison of Biological Reference Points
<p>Spot were sampled from the Chesapeake Bay commercial fishery from 1993–1995 to determine if spot are overfished. Transversely sectioned otoliths were determined to be the most appropriate structure for ageing spot. It was determined that spot have a high natural mortality rate (M = 0.9) and fast …

Consumer expectations of services and their effect on perceived service quality
… which seems to indicate that expectations act as reference points for the evaluation of perceived performance in the evaluation of service quality. There is also evidence which indicates that services' marketing practitioners also believe expectations are reference points. However, the two …

Spatial and temporal heterogeneity in life history and productivity trends of Atlantic Weakfish (Cynoscion regalis) and implications to fisheries management
… to examine the sensitivity of biological reference points to spatial and temporal variation in life history attributes (Chapter Three). Mixed-effects life history models incorporating spatial and temporal variation revealed distinct regional and annual trends that were not visible from …

Design and implementation of multiple user mobile robot following system
… the capability of determining its location in reference to know reference points and correct address. The implementation involved the use of ultrasound to determine the distance between the robot and known reference points and infrared decoder and decoder to determine the correct leader. From …

Improved Calculation and Display for Dose Distributions Associated With Intrauterine Radiotherapy.
… x-ray projections. The dosages delivered to reference points A and B are calculated. In addition, isodose curves are constructed on selected planes from which approximate three-dimensional dose distributions can be reconstructed.

Development and characterization of methodology and technology for the alignment of fMRI time series
… a head coordinate system on the basis of three reference points that lie on the directions correspondent to two of the eigenvectors of inertia of the volume, at the intersections with the head boundary. The eigenvectors are found weighting the inertia components with the voxel's intensity values …

William Sterndale Bennett's Fantasia in Its Historical Context
… time, and provides a number of comparative reference points to his fantasia, Op. 16. Two fantasias of the most influential composers according to Bennett---Mozart and Mendelssohn---are also examined as plausible sources of inspiration, yet even allowing for his fervent admiration of the …

A study of the playful use of English among learners on an intensive language course
… language proficiency and common socio-cultural reference points. The setting for this investigation was an intensive English course for business people, run by a private training organisation. The participants were low-proficiency learners from various professional fields and nationalities. The …

Development of the Spectral-Analysis-of-Body-Waves (SABW) method for downhole seismic testing with boreholes or penetrometers
… the time differences of first-arrivals or other reference points early in the time-domain signals have been used to calculate shear and compression wave velocities in soil and rock layers. This time-domain method requires an operator to pick the first arrival or other reference point of each …

A Study of Variability in Locating the External Reference Point for Central Venous Pressure Determination
… in locating, with two methods, the external reference point for central venous pressure (CVP) determinations. In the literature on CVP and on CVP value discrepancies, no reports were found of studies related to variability among medical personnel in locating the point.</p> <p>The nurse …

Reframing Duggan-Cronin: examining the recent emergence of Alfred Martin Duggan-Cronin's photographs in art exhibitions
… in Duggan- Cronin's own time, as anthropological reference points. It also explores possible reasons for this apparent shift, as well as possible reasons for the re-emergence of the photographs in the first place. In particular the study engages with the subjects of photography, curation, …

Assessment of the South Atlantic Red Porgy (<i>Pagrus pagrus</i>) Population Under a Moratorium
… in these simulations. I found that biological reference points, such as biomass and fishing mortality, and population projections were more variable for longer simulated moratoria. When fishery-dependent data were removed, minor fluctuations in length and age frequencies resulted in larger …

Highly Accurate Ultrasonic Positioning and Tracking Systems
… information. For the accurate positioning of reference points in an indoor environment, it is logistically simpler if they are installed in a fixed plane. This means that the distances between the reference points will usually be smaller than the distances between the reference points and the …

Discrete-time observers for inertial navigation systems
… measurements, such as distances to time-varying reference points, is discussed. Effects of bounded errors on model and measurements are quantified, and can be used for active measurement selection. Work on vehicle state computation is carried out by using a similar observer design method. …
