Ion-Molecule Reactions Of O,S-Dimethyl Methylphosphonothioate: Evidence For Intramolecular Sulfur Oxidation During Vx Perhydrolysis, Jilliarne Williams, Martin Paine, Stephen J. Blanksby, Michael L. Rogers, Andrew M. Mcanoy Oct 2010

Ion-Molecule Reactions Of O,S-Dimethyl Methylphosphonothioate: Evidence For Intramolecular Sulfur Oxidation During Vx Perhydrolysis, Jilliarne Williams, Martin Paine, Stephen J. Blanksby, Michael L. Rogers, Andrew M. Mcanoy

Stephen Blanksby

The alkaline perhydrolysis of the nerve agent O-ethyl S-[2-(diisopropylamino)ethyl] methylphosphonothioate (VX) was investigated by studying the ion-molecule reactions of HOO- with O,S-dimethyl methylphosphonothioate in a modified linear ion-trap mass spectrometer. In addition to simple proton transfer, two other abundant product ions are observed at m/z 125 and 109 corresponding to the S-methyl methylphosphonothioate and methyl methylphosphonate anions, respectively. The structure of these product ions is demonstrated by a combination of collision-induced dissociation and isotope-labeling experiments that also provide evidence for their formation by nucleophilic reaction pathways, namely, (i) S(N)2 at carbon to yield the S-methyl methylphosphonothioate anion and (ii) nucleophilic …


Seeking Truth On The Other Side Of The Wall: Greenleaf’S Evangelists Meet The Federal Rules, Naturalism, And Judas, Nancy J. Kippenhan Oct 2010

Seeking Truth On The Other Side Of The Wall: Greenleaf’S Evangelists Meet The Federal Rules, Naturalism, And Judas, Nancy J. Kippenhan

Faculty Publications and Presentations

An inquiry that seeks truth by accepting only natural answers excludes the possibility of the sacred or supernatural, building a wall that forecloses a complete exploration for the truth it seeks. Without analysis, critics dismiss sources presenting supernatural explanations, and those who believe sacred works have no factual foundation accept without investigation any popular theory that appears attractive. The rules of evidence expressly seek truth, wherever it lies. Noted legal scholar Simon Greenleaf used evidentiary principles to demonstrate the factual credibility of the Gospels in his Testimony of the Evangelists. This Article examines Greenleaf’s analysis, applying current rules of evidence …


Criminal Profiling As Expert Evidence, Wayne Petherick, David Field, Andrew Lowe, Elizabeth Fry Sep 2010

Criminal Profiling As Expert Evidence, Wayne Petherick, David Field, Andrew Lowe, Elizabeth Fry

Wayne Petherick

Extract:
Profiling evidence has been accepted in courts in the United States in both trial and sentencing phases, but other jurisdictions have been more cautious in their acceptance. For example, courts in the United Kingdom and Australia have been reluctant to introduce profilers as experts, even though profiling has been given some exposure in courts operating at the lower end of the justice system. The reasons for this reluctance are varied but include a lack of uniformity processes and outcomes, fragmentation of methods, and conflict between profiling organizations and practitioners. In short, there are many methods of profiling, and not …


Forensic Science Evidence And Judicial Bias In Criminal Cases, Hon. Donald E. Shelton Jan 2010

Forensic Science Evidence And Judicial Bias In Criminal Cases, Hon. Donald E. Shelton

Hon. Donald E. Shelton

Although DNA exonerations and the NAS report have raised serious questions about the validity of many traditional non-DNA forms of forensic science evidence, criminal court judges continue to admit virtually all prosecution-proferred expert testimony. It is is suggested that this is the result of a systemic pro-prosecution bias by judges that is reflected in admissibility decisions. These "attitudinal blinders" are especially prevalent in state criminal trial and appellate courts.


Disproportional Ownership Structure And Pay-Performance Relationship: Evidence From China's Listed Firms, Jerry Cao, Xiaofei Pan, Gary G. Tian Jan 2010

Disproportional Ownership Structure And Pay-Performance Relationship: Evidence From China's Listed Firms, Jerry Cao, Xiaofei Pan, Gary G. Tian

Faculty of Commerce - Papers (Archive)

This paper examines the impact of disproportional ownership structure on the pay-performance relationship in China’s listed firms. We find that the cash flow rights of the ultimate controlling shareholder have a positive effect on this relationship while a divergence between the control rights and cash flow rights has a significantly negative effect. By dividing our sample into state owned enterprises (SOE), state assets management bureaus (SAMB), and privately controlled firms, we find that cash flow rights in SOE controlled firms have a significant impact on accounting based pay performance and cash flow rights in privately controlled firms also affect the …


Identifying And Measuring Factors Of Technical Inefficiency: Evidence From Unbalanced Panel Data Of Thai Listed Manufacturing Enterprises, Yot Amornkitvikai, Charles Harvie Jan 2010

Identifying And Measuring Factors Of Technical Inefficiency: Evidence From Unbalanced Panel Data Of Thai Listed Manufacturing Enterprises, Yot Amornkitvikai, Charles Harvie

Faculty of Commerce - Papers (Archive)

This study employs stochastic frontier analysis (SFA) and two-stage DEA approaches to predict firm technical efficiency and analyse an inefficiency effects model. Aggregate translog stochastic frontier production functions are estimated under the SFA approach using an unbalanced panel data of 178 Thai manufacturing enterprises listed in the Stock Exchange of Thailand (SET), covering the period 2000 to 2008. The maximum-likelihood Tobit model is used to conduct the second-stage of the two-stage DEA model to investigate the relationship between technical inefficiency and environmental variables. Both parametric and non-parametric approaches are found to produce consistent results. The empirical evidence from both approaches …


Capital Structure And Its Implications: Empirical Evidence From An Emerging Market In South Asia, Athula S. Manawaduge, Anura De Zoysa, Palli Mulla K A Chandrakumara Jan 2010

Capital Structure And Its Implications: Empirical Evidence From An Emerging Market In South Asia, Athula S. Manawaduge, Anura De Zoysa, Palli Mulla K A Chandrakumara

Using panel data regression analysis for a sample of 171 companies, this paper examines the implications of capital structure of corporate entities in an emerging market, Sri Lanka. The results demonstrate that most of the Sri Lankan firms finance their operations with short-term debt capital as against the long-term debt capital. It provides strong evidence to indicate that debt capital has a negative impact on firm performance. The study also found a significant negative relationship between tangibility and performance indicating inefficient utilization of non-current assets. The negative performance implications associated with over-utilization of short-term debts and the under-utilization non-current assets …


Evidence Of Solar And Tropical-Ocean Forcing Of Hydroclimate Cycles In Southeastern Australia For The Past 6500 Years, Hamish A. Mcgowan, Samuel K. Marx, Joshua Soderholm, John Denholm Jan 2010

Evidence Of Solar And Tropical-Ocean Forcing Of Hydroclimate Cycles In Southeastern Australia For The Past 6500 Years, Hamish A. Mcgowan, Samuel K. Marx, Joshua Soderholm, John Denholm

Faculty of Science - Papers (Archive)

Evidence of solar and tropical‐ocean forcing of climate cycles has been found in numerous palaeoclimate records. Numerical modelling studies show physical mechanisms by which direct and indirect solar forcing may affect climate, while there is mounting evidence of solar forcing of tropical ocean‐atmosphere teleconnections. This study has developed a 6500 year record of dust deposition, a proxy for regional hydroclimate variability for the Snowy Mountains region of Australia. Spectral analysis of the record provides evidence of statistically significant cycles in dust deposition of 35–43 years, 62–73 years, 161 years and 2200 years. These correlate with variability in solar irradiance and …

The Hydraulic Geometry Of Narrow And Deep Channels; Evidence For Flow Optimisation And Controlled Peatland Growth, Rachel Nanson, Gerald C. Nanson, He Qing Huang Jan 2010

The Hydraulic Geometry Of Narrow And Deep Channels; Evidence For Flow Optimisation And Controlled Peatland Growth, Rachel Nanson, Gerald C. Nanson, He Qing Huang

Faculty of Science - Papers (Archive)

At-a-station and bankfull hydraulic geometry analyses of peatland channels at Barrington Tops, New South Wales, Australia, reveal adjustments in self-forming channels in the absence of sediment load. Using Rhodes ternary diagram, comparisons are made with hydraulic geometry data from self-forming channels carrying bedload in alluvial settings elsewhere. Despite constraints on channel depths caused at some locations by the restricted thickness of peat, most stations have cohesive, near-vertical, well-vegetated banks, and width/depth (w/d) ratios of similar to 2 that are optimal for sediment-free flow. Because banks are strong, resist erosion and can stand nearly vertical, and depth is sometimes constrained, adjustments …


Evidence For Specific Subunit Distribution And Interactions In The Quaternary Structure Of Α-Crystallin, Amie M. Morris, J Andrew Aquilina Jan 2010

Evidence For Specific Subunit Distribution And Interactions In The Quaternary Structure Of Α-Crystallin, Amie M. Morris, J Andrew Aquilina

Faculty of Science - Papers (Archive)

The quaternary structure of alpha-crystallin is dynamic, a property which has thwarted crystallographic efforts towards structural characterization. In this study, we have used collision-induced dissociation mass spectrometry to examine the architecture of the polydisperse assemblies of alpha-crystallin. For total alpha-crystallin isolated directly from fetal calf lens using size-based chromatography, the alpha B-crystallin subunit was found to be preferentially dissociated from the oligomers, despite being significantly less abundant overall than the alpha A-crystallin subunits. Furthermore, upon mixing molar equivalents of purified alpha A- and alpha B-crystallin, the levels of their dissociation were found to decrease and increase, respectively, with time. Interestingly …

Outsourcing Investigations, Elena Baylis

Articles

This article addresses the International Criminal Court’s reliance on third-party investigations in the absence of its own international police force. In addition to cooperation from sometimes reluctant states, the ICC and other international criminal tribunals have come to rely on a network of NGOs and UN entities focused on postconflict justice work to provide critical evidence. This reliance raised problems in the ICC Office of the Prosecutor's first case against Thomas Lubanga. The use of third-party evidence raises questions regarding confidentiality and disclosure, the integrity of the evidence-gathering process, and the equality of arms between the prosecution and the defense. …
