Social Work Ethics Computer-Based Training Minnesota State University, Mankato Department of Social Work
At the Community Behavioral Health Hospital, St.Peter (CBHH),a discussion was held regarding Ethics Continuing Education Hours(CEUs). The Minnesota Board of Social Work(MNBSW)and Minnesota State Statute 148D.130 require that Licensed Social Workers receive two hours of ethics-specific CEUsper licensure renewal. Through this discussion,it appeared that it would be beneficial to create an ethics computer-based training(CBT), which would be of no expense to State Operated Services(SOS)Social Workers.This option would also provide convenience for social workers, who as a majority,reside within rural areas.The CBT created is in accordance to requirements of the MNBSW and has an emphasis to include the National Association of Social Workers(NASW) Code of Ethics
FAULT MORPHOLOGY WITHIN THE SOUTHERN KENYAN PORTION OF THE EAST AFRICAN RIFT VALLEY
Faults form quickly, geologically speaking, with sharp, crisp step-like profiles. Logic dictates that erosion wears away this sharpness or angularity creating more rounded features. As erosion occurs, debris accumulates at the base of the scarp slope. The stable end point of this process is when the scarp slope approaches an ideal sigmoid shape.
This theory of fault end process, in combination with a new method developed in this report for fault profile delineation, has the potential to enable observation and categorization of fault profiles over large, diverse swaths of fault formation-- in remote areas such as the Southern Kenyan Rift Valley. This up-to date method uses remote sensing data and the digitizer tool in Global Mapper to create shape files of fault segments.
This method can provide further evidence to support the notion that sigmoidal- shaped profiles represent a natural endpoint of the erosional process of fault scarps. Over time, faults of many different ages would exist in this similar shape over a wide region. However, keeping in mind that other processes can be at work on scarps-- most notably drainage patterns, when anomalies in profiles are observed, reactivation in some form possibly has occurred
Critical Test of Simulations of Charge-Exchange-Induced X-Ray Emission in the Solar System
Experimental and theoretical state-selective X-ray spectra resulting from
single-electron capture in charge exchange (CX) collisions of Ne^10+ with He,
Ne, and Ar are presented for a collision velocity of 933 km s^-1 (4.54 keV
nucleon^-1), comparable to the highest velocity components of the fast solar
wind. The experimental spectra were obtained by detecting scattered
projectiles, target recoil ions, and X-rays in coincidence; with simultaneous
determination of the recoil ion momenta. Use and interpretation of these
spectra are free from the complications of non-coincident total X-ray
measurements that do not differentiate between the primary reaction channels.
The spectra offer the opportunity to test critically the ability of CX theories
to describe such interactions at the quantum orbital angular momentum level of
the final projectile ion. To this end, new classical trajectory Monte Carlo
calculations are compared here with the measurements. The current work
demonstrates that modeling of cometary, heliospheric, planetary, and laboratory
X-ray emission based on approximate state-selective CX models may result in
erroneous conclusions and deductions of relevant parameters.Comment: 4 figure
A 33 year constancy of the X-ray coronae of AR Lac and eclipse diagnosis of scale height
Extensive X-ray and extreme ultraviolet (EUV) photometric observations of the
eclipsing RS CVn system AR Lac were obtained over the years 1997 to 2013 with
the Chandra X-ray Observatory Extreme Ultraviolet Explorer. During primary
eclipse, HRC count rates decrease by ~40%. A similar minimum is seen during one
primary eclipse observed by EUVE but not in others owing to intrinsic source
variability. Little evidence for secondary eclipses is present in either the
X-ray or EUV data, reminiscent of earlier X-ray and EUV observations. Primary
eclipses allow us to estimate the extent of a spherically symmetric corona on
the primary G star of about 1.3Rsun, or 0.86Rstar, and indicate the G star is
likely brighter than the K component by a factor of 2-5. Brightness changes not
attributable to eclipses appear to be dominated by stochastic variability and
are generally non-repeating. X-ray and EUV light curves cannot therefore be
reliably used to reconstruct the spatial distribution of emission assuming only
eclipses and rotational modulation are at work. Moderate flaring is observed,
where count rates increase by up to a factor of three above quiescence.
Combined with older ASCA, Einstein, EXOSAT, ROSAT and Beppo-SAX observations,
the data show that the level of quiescent coronal emission at X-ray wavelengths
has remained remarkably constant over 33 years, with no sign of variation due
to magnetic cycles. Variations in base level X-ray emission seen by Chandra
over 13 years are only ~10%, while variations back to pioneering Einstein
observations in 1980 amount to a maximum of 45% and more typically about 15%.Comment: To appear in the Astrophysical Journa
One-Up On L1: Can X-rays Provide Longer Advanced Warning of Solar Wind Flux Enhancements Than Upstream Monitors?
Observations of strong solar wind proton flux correlations with ROSAT X-ray
rates along with high spectral resolution Chandra observations of X-rays from
the dark Moon show that soft X-ray emission mirrors the behavior of the solar
wind. In this paper, based on an analysis of an X-ray event observed by
XMM-Newton resulting from charge exchange of high charge state solar wind ions
and contemporaneous neutral solar wind data, we argue that X-ray observations
may be able to provide reliable advance warning, perhaps by as much as half a
day, of dramatic increases in solar wind flux at Earth. Like neutral atom
imaging, this provides the capability to monitor the solar wind remotely rather
than in-situ.Comment: in press in Adv. Space Research, 7 pages, 6 eps figures, resolution
