Predicting Registered Health Information Administrator Examination Scores
The purpose of this study was to determine whether differences existed among candidates for the Registered Health Information Administrator certification examination that may have characterized the likelihood of acquiring professional certification upon graduation from accredited health information administration education programs. The research was conducted using data acquired from accredited health information administration education programs located across the United States. A total of 197 former student records were obtained and used in the statistical analyses; 118 were employed in correlation analysis and to develop a Registered Health Information Administrator certification examination success prediction model and to establish a 95% Approximate Prediction Interval, while the remaining 79 records were used to validate the success prediction model. Ten independent variables were evaluated: race, ethnicity, mother tongue, age, four professional course grades, and two grade point averages. The dependent variable was the graduate’s raw score of the first attempt on the Registered Health Information Administrator certification examination. Results of Pearson product-moment correlation coefficient computations revealed that final course grades in Coding and Introduction to Health Information Administration and professional curriculum grade point average wer

Joint Study of the 1952 Kern County, California Earthquake
Our understanding of earthquakes that occurred prior to the establishment of the World-Wide Standardized Seismographic Network (WWSSN) is generally limited by the availability of high-quality geophysical observations. As a result, significant variability exists among source studies for important seismic events such as the historic 1952 Kern County, California earthquake. Here, combining reported geodetic observations with a collection of previously unused, local seismic recordings, we conduct a series of inversions to constrain a slip model for the main rupture. Our results suggest that it initiates on a low-angle fault plane with dominant strike-slip motion (strike=49±3°; dip=35±1°; and rake=11±5°) then triggers an abnormally energetic rupture on a high-angle fault plane (strike = 51°, dip = 75°), 2 s later. This energetic rupture, contained within a 9×6 km patch near the hypocenter, accumulates 6–7 m of slip and has a high average static stress-drop (larger than 50 MPa). P-waves excited by this powerful sub-event saturates seismic recordings as far as Berkeley (approximately 430 km away). The total rupture has a duration 23–26 s and a cumulative moment of 7.61×10^{19} Nm, or Mw 7.18. The majority of moment release occurs within a 36 km section in the southwest portion of White Wolf fault (assumed to be 60 km long). The weighted, average rake-angle over the southwest segment of the fault is 47–57°, falling between previous results based on individual seismic or geodetic data sets. Investigation of the regional velocity structure reveals high P-wave velocities near the southwest portion of the White Wolf fault, adjacent to the presumed hypocenter

National Rugby League athletes and tendon tap reflex assessment: A matched cohort clinical study
BACKGROUND: Limited research suggests elite athletes may differ from non-athletes in clinical tendon tap reflex responses. METHODS: In this matched cohort study, 25 elite rugby league athletes were compared with 29 non-athletes to examine differences in tendon reflex responses. Relationships between reflex responses and lengths of players’ careers were also examined. Biceps, triceps, patellar and Achilles tendon reflexes were clinically assessed. RESULTS: Right and left reflexes were well correlated for each tendon (r(S) = 0.7–0.9). The elite rugby league athletes exhibited significantly weaker reflex responses than non-athletes in all four tendons (p < 0.005). Biceps reflexes demonstrated the largest difference and Achilles reflexes the smallest difference. Moderate negative correlations (r(S) = −0.3–0.6) were observed between reflex responses and lengths of players’ careers. CONCLUSIONS: Future research is required to further elucidate mechanisms resulting in the observed differences in tendon reflexes and to ensure clinical tendon tap examinations and findings can be interpreted appropriately in this athletic population
Higher Education Financial Assistance Tools for Middle- and Upper-Income Taxpayers
This article describes higher education financial assistance tools designed mainly for students of middle- and upper-income families who may not be eligible for financial aid from other sources. It includes the 2007 legislative updates for these tools, all of which have been devised and offered by either state or federal governments. The authors discuss the advantages and disadvantages of each tool and offer planning suggestions for families, students, and others who may participate in the higher education financial planning process
Sample variance, source clustering and their influence on the counts of faint radio sources
The shape of the curves defined by the counts of radio sources per unit area as a function of their
flux density was one of the earliest cosmological probes. Radio source counts continue to be
an area of astrophysical interest as they can be used to study the relative populations of galaxy
types in the Universe (as well as investigate any cosmological evolution in their respective
luminosity functions). They are also a vital consideration for determining howsource confusion
may limit the depth of a radio interferometer observation, and are essential for characterizing
the extragalactic foregrounds in cosmicmicrowave background experiments. There is currently
no consensus as to the relative populations of the faintest (sub-mJy) source types, where the
counts show a turn-up. Most of the source count data in this regime are gathered from multiple
observations that each use a deep, single pointing with an interferometric radio telescope.
These independent count measurements exhibit large amounts of scatter (factors of the order
of a few) that significantly exceeds their respective stated uncertainties. In this paper, we
use a simulation of the extragalactic radio continuum emission to assess the level at which
sample variance may be the cause of the scatter. We find that the scatter induced by sample
variance in the simulated counts decreases towards lower flux density bins as the raw source
counts increase. The field-to-field variations make significant contributions to the scatter in
the measurements of counts derived from deep observations that consist of a single pointing,
and could even be the sole cause at >100 μJy. We present a method for evaluating the flux
density limit that a radio survey must reach in order to reduce the count uncertainty induced by
sample variance to a specific value. We also derive a method for correcting Poisson errors on
source counts from existing and future deep radio surveys in order to include the uncertainties
due to the cosmological clustering of sources. A conclusive empirical constraint on the effect
of sample variance at these low luminosities is unlikely to arise until the completion of future
large-scale radio surveys with next-generation radio telescopes.Web of Scienc
