Positively Identifying Children As Citizens: A Call For Parallel Due Process Rights, Margot Elizabeth Rudy Jan 2004

Positively Identifying Children As Citizens: A Call For Parallel Due Process Rights, Margot Elizabeth Rudy

UNLV Retrospective Theses & Dissertations

This work addresses the need for parallel due process rights for children by investigating the nature of juvenile welfare policies that affect abused and neglected children by focusing on the Adoption Safe Families Act. Upon the settlement of the U.S., common law from England, known as parens patriae, has governed the juvenile justice system. This common law has recognized children are indeed a State interest and that a child is a different type of citizen than an adult. Because children are dependant on their parents and not seen as full-fledged citizens, the State has assumed the responsibility of ensuring that …

Elevated Temperature Mechanical Properties And Corrosion Characteristics Evaluation Of Alloy Ht-9, Bhagath Yarlagadda Jan 2004

Elevated Temperature Mechanical Properties And Corrosion Characteristics Evaluation Of Alloy Ht-9, Bhagath Yarlagadda

UNLV Retrospective Theses & Dissertations

This thesis presents the results of tensile testing, stress corrosion cracking (SCC) and localized corrosion studies of Alloy HT-9, which is currently being considered as a target structural material for transmutation applications. The results of tensile testing indicate that the yield strength and the ultimate tensile strength were gradually reduced with increasing temperature, but the ductility parameters were enhanced due to increased plastic deformation, irrespective of the tempering time. The results of SCC testing in the 90°C acidic solution, performed by the slow-strain-rate (SSR) technique, revealed higher failure stress (sigmaf) at longer tempering time. Localized corrosion studies conducted by polarization …

Prediction Of Struvite Formation Potential In Ebpr Digested Sludge Using Mass Balances, Batch Precipitation Tests, And Chemical Equilibrium Modeling, Hyunju Jeong Jan 2004

Prediction Of Struvite Formation Potential In Ebpr Digested Sludge Using Mass Balances, Batch Precipitation Tests, And Chemical Equilibrium Modeling, Hyunju Jeong

UNLV Retrospective Theses & Dissertations

Digested sludge liquors from wastewater treatment plants that include enhanced biological phosphorus removal (EBPR) in their treatment process have the potential to form struvite (MgNH4PO4·6H 2O). The potential can be determined by the concentrations of struvite constituents including phosphorus, ammonium, and magnesium. Phosphorus concentration of digested sludge liquors is expected to increase when EBPR is introduced to wastewater treatment plants because phosphorus accumulating organisms (PAOs) can accumulate phosphorus beyond their metabolic needs and phosphosphorus can be relased when they are digested anaerobically. The work presented in this thesis focuses on determining the potential for struvite formation at the City of …

Ellis Island: The Public And Personal Representations Of The Immigrant Experience, Tara Maras Jan 2004

Ellis Island: The Public And Personal Representations Of The Immigrant Experience, Tara Maras

UNLV Retrospective Theses & Dissertations

Between 1892 and 1954, more than 12 million immigrants arrived at Ellis Island's shores for the promise of a new beginning in America. During this period of immigrant influx and in the decades to follow, anti-immigrant sentiment remained at the forefront of the collective American conscious, varying in severity, though ever present. This study compares the relationship between the personal stories of immigrants and the print media's account of immigration in Ellis Island's peak year, 1907, in an attempt to understand how storytelling, as communication, helped shape the collective immigrant experience. It also examines how the relationship contributes to U.S. …

Current Video Compression Algorithms: Comparisons, Optimizations, And Improvements, Douglas Scott Price Jan 2004

Current Video Compression Algorithms: Comparisons, Optimizations, And Improvements, Douglas Scott Price

UNLV Retrospective Theses & Dissertations

Compression algorithms have evolved significantly in recent years. Audio, still image, and video can be compressed significantly by taking advantage of the natural redundancies that occur within them. Video compression in particular has made significant advances. MPEG-1 and MPEG-2, two of the major video compression standards, allowed video to be compressed at very low bit rates compared to the original video. The compression ratio for video that is perceptually lossless (losses can't be visually perceived) can even be as high as 40 or 50 to 1 for certain videos. Videos with a small degradation in quality can be compressed at …

Instrumentation Of Ysz Oxygen Sensor Calibration In Lead-Bismuth Eutectic, Xiaolong Wu Jan 2004

Instrumentation Of Ysz Oxygen Sensor Calibration In Lead-Bismuth Eutectic, Xiaolong Wu

UNLV Retrospective Theses & Dissertations

Although liquid lead-bismuth eutectic (LBE) is a good candidate for the coolant in the subcritical transmutation blanket, it is also known to be very corrosive to stainless steel, the material of the carrying tubes and the containers. Such a corrosion problem can be prevented by producing and maintaining a protective oxide layer on the exposed surface of stainless steel. Proper formation of the oxide layer critically depends on the accurate measurement and control of the oxygen concentration (tens of ppb levels) in the liquid LBE. An Oxygen Sensor Calibration/Measurement Apparatus is designed and built to deliberately calibrate the Yttria Stabilized …

Specialization In The Criminal Careers Of Sex Offenders, Jodi K Olson Jan 2004

Specialization In The Criminal Careers Of Sex Offenders, Jodi K Olson

UNLV Retrospective Theses & Dissertations

Recent public policy has been implemented with the assumption that sex offenders are highly motivated and tend to exhibit specialization and compulsivity in their offending patterns. Past research has not been able to confirm or invalidate this assumption, and has reflected many inconsistencies when drawing conclusions about sex offender profiles and career trajectories; Drawing upon a national sample of offenders, the current study examines the degree of specialization in the criminal careers of sex offenders and other groups of offenders. Results from the adjacent specialization analyses of the general offense categories indicated that sex offenders are among the least specialized …

Culture Clash: Making The Case For A New Paradigm In Police Cultural Training, Hal S Edwards Jan 2004

Culture Clash: Making The Case For A New Paradigm In Police Cultural Training, Hal S Edwards

UNLV Retrospective Theses & Dissertations

Hiring standards in most police agencies result in most officer candidates having little, if any, meaningful exposure to the "oppositional" culture of the urban, minority poor. Given the current popularity of the Community Oriented Policing paradigm---with its emphasis on positive police/community relations---current police hiring and training practices handicap police agencies in their efforts to gain the trust of urban, minority communities. A content analysis of United States Department of Justice Civil Rights Division investigations under the Violent Crime Control and Law Enforcement Act of 1994 (42 U.S.C. 14141) was found to support the hypothesis that the interface between the police …

Influence Of Varying Intensities Of Natural Area On-Site Interpretation On Attitudes And Knowledge, Michael Hughes Jan 2004

Influence Of Varying Intensities Of Natural Area On-Site Interpretation On Attitudes And Knowledge, Michael Hughes

Theses

Using interpretation as a means of influencing attitudes and knowledge is a core component of natural area management practice. However, this aspect of on-site interpretation is rarely assessed when evaluating natural area management success. This thesis examined the immediate influence of different intensities of on-site interpretation on attitudes and knowledge of visitors to natural areas. Measuring the immediate (short term) influence of a site experience enables clearer links to be made between survey responses and interpretation used at a specific site, something long term surveys are less able to achieve. Two sites from Western Australia (the Tree Top Walk and …
