Review of Preventative Controls for Fraud, Waste, and Abuse in the Supplemental Nutrition Assistance Program (SNAP), Department of Social Services

This review of preventative controls for fraud, waste, and abuse in the Supplemental Nutrition Assistance Program (SNAP), administered by the Department of Social Services, was self-initiated by the State Inspector General as part of a broader statewide review of preventative fraud, waste, and abuse management controls of major benefit programs in State agencies. This review’s scope and objectives were: Assess SNAP’s preventative management controls for fraud, waste, and abuse; Identify SNAP preventative management control best practices; and Identify opportunities to improve SNAP management controls to cost/effectively mitigate risks of fraud, waste, and abuse.

Review of Managing the Fraud Risk in the Disaster Supplemental Nutrition Assistance Program (D-SNAP), Administered by the Department of Social Services

This review was initiated based upon allegations from multiple sources of possible fraud in the Disaster Supplemental Nutrition Assistance Program (D-SNAP) administered by the South Carolina Department of Social Services (SCDSS), which was implemented in response to the 10/3/2015 statewide flooding from Hurricane Joaquin. This review’s scope and objectives were: Assess SCDSS’s D-SNAP implementation for compliance with federal guidelines, with emphasis on fraud preventative controls; Assess the SCDSS’s post-disaster review and audit methodology for compliance with federal guidelines, with emphasis on understanding the fraud risks and resolution strategies; and Identify residual risk/suspected fraud not addressed through the SCDSS review and available opportunities to address.

Metamorphic epiphany -- 3D animation

As far back as I can remember, I have always been interested in studio art. Whether it be painting, drawing, printmaking, or photography, it has consistently been a part of my life. Upon enrolling in Colby, I became interested in computers and decided to major my undergraduate college career in Computer Science. Not forgetting past interests, I continued my studio art education, taking several classes within the Art department. In due time, I began combining interests and began studying Computer Graphics and Design. With limited resources in this field at Colby, the majority of my computer graphic education and experience has been done on my own time apart from regular classroom work. As time progressed, so did my interests. Starting with simple image manipulation of digitally scanned photographs, I moved on to Web Page design, eventually leading to Desktop Publishing. Ultimately, I wanted to take a step further and expand my overall computer graphic knowledge by learning 3D modeling and animation. With even fewer resources in 3D animation at Colby, I perceived having trouble finding the information and tools I would need to gain the necessary skills for this new field. The Senior Scholars program gave me the opponunity to find and acquire the necessary tools to pursue my interest. This program also allowed me to devote the proper amount of time required for learning these new tools.

Vanadium-Doped In and Sn Sulphides: Photocatalysts able to use the whole visible light spectrum

Using photocatalysis for energy applications depends, more than for environmental purposes or selective chemical synthesis, on converting as much of the solar spectrum as possible; the best photocatalyst, titania, is far from this. Many efforts are pursued to use better that spectrum in photocatalysis, by doping titania or using other materials (mainly oxides, nitrides and sulphides) to obtain a lower bandgap, even if this means decreasing the chemical potential of the electron-hole pairs. Here we introduce an alternative scheme, using an idea recently proposed for photovoltaics: the intermediate band (IB) materials. It consists in introducing in the gap of a semiconductor an intermediate level which, acting like a stepstone, allows an electron jumping from the valence band to the conduction band in two steps, each one absorbing one sub-bandgap photon. For this the IB must be partially filled, to allow both sub-bandgap transitions to proceed at comparable rates; must be made of delocalized states to minimize nonradiative recombination; and should not communicate electronically with the outer world. For photovoltaic use the optimum efficiency so achievable, over 1.5 times that given by a normal semiconductor, is obtained with an overall bandgap around 2.0 eV (which would be near-optimal also for water phtosplitting). Note that this scheme differs from the doping principle usually considered in photocatalysis, which just tries to decrease the bandgap; its aim is to keep the full bandgap chemical potential but using also lower energy photons. In the past we have proposed several IB materials based on extensively doping known semiconductors with light transition metals, checking first of all with quantum calculations that the desired IB structure results. Subsequently we have synthesized in powder form two of them: the thiospinel In2S3 and the layered compound SnS2 (having bandgaps of 2.0 and 2.2 eV respectively) where the octahedral cation is substituted at a â?10% level with vanadium, and we have verified that this substitution introduces in the absorption spectrum the sub-bandgap features predicted by the calculations. With these materials we have verified, using a simple reaction (formic acid oxidation), that the photocatalytic spectral response is indeed extended to longer wavelengths, being able to use even 700 nm photons, without largely degrading the response for above-bandgap photons (i.e. strong recombination is not induced) [3b, 4]. These materials are thus promising for efficient photoevolution of hydrogen from water; work on this is being pursued, the results of which will be presented.
