The Effects Of The Jccs Curriculum On Juveniles' Legal Knowledge, Competency, And Anxiety, Leslie Strasser Murdock

UNLV Theses, Dissertations, Professional Papers, and Capstones

Current law requires that juveniles be competent to stand trial prior to their involvement as defendants in court. According to Dusky v. US, a defendant must have a rational and factual understanding of the court proceedings to be deemed competent to stand trial. Past studies call into question whether juveniles at any age could meet the understanding element of the standard articulated in Dusky v. US (1960). Additionally, youth with disabilities have less knowledge than their typical peers. Besides a lack of legal knowledge, court related anxiety has also been found to have a significant effect on youths going to …

On High-Performance Parallel Fixed-Point Decimal Multiplier Designs, Ming Zhu

UNLV Theses, Dissertations, Professional Papers, and Capstones

High-performance, area-efficient hardware implementation of decimal multiplication is preferred to slow software simulations in a number of key scientific and financial application areas, where errors caused by converting decimal numbers into their approximate binary representations are not acceptable.

Multi-digit parallel decimal multipliers involve two major stages: (i) the partial product generation (PPG) stage, where decimal partial products are determined by selecting the right versions of the pre-computed multiples of the multiplicand, followed by (ii) the partial product accumulation (PPA) stage, where all the partial products are shifted and then added together to obtain the final multiplication product. In this thesis, …

The Hotel Manager’S Perceived Conflict Of Providing For Hospitality And Security: Can The Two Exist In Harmony?, Silvano Cozzini

UNLV Theses, Dissertations, Professional Papers, and Capstones

The hospitality industry relies upon regular and repeat customers for its survival. No traveler or visitor will return to a hotel property where a bad incident occurred. Would a diner go back to any restaurant where they were sickened by their meal? Would a hotel guest return to any property where they were a victim of a crime? Bad experiences make us tell ourselves, “I will never go back there again!”

This same psychology holds true for criminals. At places where they have been deterred by a high security presence, it is unlikely that they would return there, either. A …

Pennsylvanian To Cretaceous Folds And Thrusts In South-Central Nevada: Evidence From The Timpahute Range, Angela Giovanna Russo

UNLV Theses, Dissertations, Professional Papers, and Capstones

Understanding Permian and Mesozoic contractional structures from southern California to northern Nevada requires correlation through south-central Nevada. After the Devonian-Mississippian Antler orogeny through the Permian-Triassic Sonoma orogeny and then up to the Sevier orogeny, south-central Nevada was thought to have remained tectonically inactive. However, Pennsylvanian through Jurassic age deformation is documented to the south in Death Valley and to the north. Identifying geometries, spatial relationships, and relative timing of deformations in the Timpahute Range, south-central Nevada, is an essential piece to completing the overall understanding of Nevada geology.
