Graduate Accounting Students' Perception Of It Forensics: A Multi-Dimensional Analysis, Grover S. Kearns

Annual ADFSL Conference on Digital Forensics, Security and Law

Forensics and information technology (IT) have become increasingly important to accountants and auditors. Undergraduate accounting students are introduced to general IT topics but discussion of forensic knowledge is limited. A few schools have introduced an undergraduate major in forensic accounting. Some graduate schools offer accounting students an emphasis in forensic or fraud accounting that includes instruction in forensics and information technology. When students do not view the IT topics as being equally important to their careers as traditional accounting topics, these attitudes may reduce the quality of the course. In an effort to assess student attitudes, a survey of 46 …

Visualization Of Honeypot Data Using Graphviz And Afterglow, Craig Valli

Annual ADFSL Conference on Digital Forensics, Security and Law

This research in progress paper explores the use of Graphviz and Afterglow for the analysis of data emanating from a honeypot system. Honeypot systems gather a wide range of data that is often difficult to readily search for patterns and trends using conventional log file analysis techniques. The data from the honeypots has been statically extracted and processed through Afterglow scripts to produce inputs suitable for use by the DOT graph based tools contained within Graphviz. This paper explores some of the benefits and drawbacks of currently using this type of approach.

Turbulence-Plankton Interactions: A New Cartoon, Peter A. Jumars, John H. Trowbridge, Emmanuel Boss, Lee Karp-Boss

Marine Sciences Faculty Scholarship

Climate change redistributes turbulence in both space and time, adding urgency to understanding of turbulence effects. Many analytic and analog models used to simulate and assess effects of turbulence on plankton rely on simple Couette flow. There shear rates are constant and spatially uniform, and hence so is vorticity. Over the last decade, however, turbulence research within fluid dynamics has focused on the structure of dissipative vortices in space and time. Vorticity gradients, finite net diffusion of vorticity and small radii of curvature of streamlines are ubiquitous features of turbulent vortices at dissipation scales but are explicitly excluded from simple, …

Incentive Based Routing Protocol For Mobile Peer To Peer Networks, Anil Jade, Sanjay Kumar Madria, Mark Linderman

Computer Science Faculty Research & Creative Works

Incentive models are becoming increasingly popular in Mobile Peer to Peer Networks (M-P2P) as these models entice node participation in return for a virtual currency to combat free riding and to effectively manage constraint resources in the network. Many routing protocols proposed are based on best effort data traffic policy, such as the shortest route selection (hop minimization). Using virtual currency to find a cost effective optimal route from the source to the destination, while considering Quality of Service (QoS) aspects such as bandwidth and service capacity constraints for data delivery, remains a challenging task due to the presence of …

Minimizing Vessel Strikes To Endangered Whales: A Crash Course In Conservation Science And Policy, David N. Wiley, Moira W. Brown

Center for Coastal and Ocean Mapping

The North Atlantic right whale is one of the most endangered of all large whales: about 350-400 individuals remain. Species recovery is, in part, contingent on reducing vessel-strike mortality. Our science-based conservation program resulted in three efforts specifically designed to minimize the risk of lethal vessel-strikes of endangered baleen whales without compromising vessel navigation and safety. In Atlantic Canada, the Bay of Fundy Traffic Separation Scheme (TSS) was relocated to reduce the risk of lethal vessel strikes by 90% where the original outbound lane of the TSS intersected the Right Whale Conservation Area, and an Area To Be Avoided (ATBA) …

Proper Motions And Brightness Variations Of Nonthermal X-Ray Filaments In The Cassiopeia A Supernova Remnant, Daniel J. Patnaude, Robert A. Fesen

Dartmouth Scholarship

We present Chandra ACIS X-ray observations of the Galactic supernova remnant Cassiopeia A taken in 2007 December. Combining these data with previous archival Chandra observations taken in 2000, 2002, and 2004, we estimate the remnant's forward shock velocity at various points around the outermost shell to range between 4200 and 5200 ± 500 km s^–1. Using these results together with previous analyses of Cas A's X-ray emission, we present a model for the evolution of Cas A and find that it's expansion is well fit by a ρ_ej ∝ r ^–(7–9) ejecta profile running into a circumstellar …

Characterisation Of The Humidity And Temperature Responses Of A Reflection Hologram Recorded In Acrylamide-Based Photopolymer, Izabela Naydenova, Raghavendra Jallapuram, Vincent Toal, Suzanne Martin

Articles

The humidity and temperature responses of a reflection hologram recorded in a self-processing photopolymer layer have been characterised by measurement of the position of the maximum intensity in the spectral response of the hologram. It has been demonstrated that such a hologram can be used for indication of the relative humidity (RH) in a specific temperature range. The operational range and reversibility of the holograms have been characterised in a controlled humidity and temperature environment. The humidity studies were carried out in the range from 10 to 80% RH and the temperature range under study was 15 – 50 ºC.

Sdss Unveils A Population Of Intrinsically Faint Cataclysmic Variables At The Minimum Orbital Period, B. T. Gänsicke, M. Dillon, J. Southworth, J. R. Thorstensen

Dartmouth Scholarship

We discuss the properties of 137 cataclysmic variables (CVs) which are included in the Sloan Digital Sky Survey (SDSS) spectroscopic data base, and for which accurate orbital periods have been measured. 92 of these systems are new discoveries from SDSS and were followed-up in more detail over the past few years. 45 systems were previously identified as CVs because of the detection of optical outbursts and/or X-ray emission, and subsequently re-identified from the SDSS spectroscopy. The period distribution of the SDSS CVs differs dramatically from that of all the previously known CVs, in particular it contains a significant accumulation of …

Observations Of River Topography And Flow Around Bridges, Thomas C. Lippmann

Center for Coastal and Ocean Mapping

This investigation was motivated by the amount of river, estuarine, and coastal infrastructure that is susceptible to extreme wave and flooding events. The high velocities and resulting shear stresses associated with high flow velocities are capable of scouring or depositing large quantities of sediment around hydraulic structures. Preventing the failure of these structures and sedimentation in inlets alone costs federal and state agencies billions of dollars annually. In addition to being costly, the manual monitoring of bridge scour - as mandated by the Federal Highway Administration - can be inefficient in states such as Ohio where the flood events that …

The Legal Ramifications Of Microchipping People In The United States Of America- A State Legislative Comparison, Angelo Friggieri, K. Michael, M.G. Michael

M. G. Michael

The ability to microchip people for unique positive identification, and for tracking and monitoring applications is becoming increasingly scrutinized by the legal profession, civil libertarians, politicians in positions of power, human rights advocates, and last but not least, citizens across jurisdictions. The United States is among the few nations internationally, that have moved to enact state-level legislation, regarding the microchipping of people in a variety of contexts. This paper provides an overview of nine state laws/bills in the United States of America that have either enacted anti-chipping legislation or have recently proposed bills regarding the enforced chipping of persons. The …

Reducing Exposures To Mercury, Sharon P. Mclelland

MALS Final Projects, 1995-2019

Mercury is an environmental contaminant affecting neurological development, the immune system and cardiac health. Air emissions become environmental pollutants impacting air, water and land. Consumption of mercury-contaminated fish can create public health concerns, primarily to pregnant women and their fetuses. New York State's public policy response addresses incidental exposures with annual fish advisories and restrictions on mercury emissions and products sold or used. Additional public policy responses to the mercury problem can include: direct notification of advisories to fish consumers, enhanced public health notification of benefits and risks of consuming fish, labeling requirements on mercury-containing products, and expanded scientific data …

Reductive Decomposition Of A Diazonium Intermediate By Dithiothreitol Affects The Determination Of Nos Turnover Rates, Perera N. Indika, Talal Sabbagh, Jean A. Boutros, Mekki Bayachou

Chemistry Faculty Publications

Accurate determination of nitrite either as such or as the breakdown product of nitric oxide (NO) is critical in a host of enzymatic reactions in various settings addressing structure–function relationships, as well as mechanisms and kinetics of molecular operation of enzymes. The most common way to quantify nitrite, for instance in nitric oxide synthase (NOS) mechanistic investigations, is the spectrophotometric assay based on the Griess reaction through external standard calibration. This assay is based on a two-step diazotization reaction, in which a cationic diazonium derivative of sulfanilamide is formed as intermediate before the final absorbing azo-product. We show that this …

Changes In Continental Freshwater Discharge From 1948 To 2004, Aiguo Dai, Taotao Qian, Kevin E. Trenberth, John D. Millliman

VIMS Articles

A new dataset of historical monthly streamflow at the farthest downstream stations for the world’s 925 largest ocean-reaching rivers has been created for community use. Available new gauge records are added to a network of gauges that covers ∼80 × 10⁶ km² or ∼80% of global ocean-draining land areas and accounts for about 73% of global total runoff. For most of the large rivers, the record for 1948–2004 is fairly complete. Data gaps in the records are filled through linear regression using streamflow simulated by a land surface model [Community Land Model, version 3 (CLM3)] forced with observed …

Selective Nanoshaving Of Self-Assembled Monolayers Of 2-(4-Pyridylethyl)Triethoxysilane, Luis G. Rosa, Jinyue Jiang, Ocelio V. Lima, Jie Xiao, Emmanuel Utreras, Peter A. Dowben, Li Tan

Peter Dowben Publications

Single molecular layers of 2-(4-pyridylethyl)triethoxysilane have been deposited on native oxide surfaces of silicon, with the triethoxysilylethyl groups towards the silicon oxide interface and pyridine at the surface. It is possible to “shave” or mechanically break the molecular bonds at the alkoxy-silane (Si–C) bond using scanning atomic force microscope, leaving large swaths of surface area cut to a depth of 0.64 ± 0.06 nm, exposing the silicon of the alkoxy-silane ligand. Mechanical cleavage of the pyridine ligand alone is also possible, but more difficult to control selectively.

Isotopic Signatures And Concentration Profiles Of Nitrous Oxide In A Rice-Based Ecosystem During The Drained Crop-Growing Season, Z. Q. Xiong, M. A. K. Khalil, G. Xing, Martha J. Shearer, Christopher Lee Butenhoff

Physics Faculty Publications and Presentations

The stable isotopic composition of nitrous oxide (N₂O) in agricultural soils can improve our understanding of the relative contributions of the main microbial processes (nitrification and denitrification) responsible for N₂O formation in soils, and can provide constraints for the atmospheric N2O budget. Here, we present soil profiles featuring N₂O concentrations and δ¹⁵N and δ¹⁸O values in N₂O over time, which permit the in situ identification of processes and sites of N₂O production in a rice-based ecosystem seeded with winter wheat. Our δ¹⁵N and δ¹⁸O soil profile values support the conclusion that denitrification is the dominant process behind N₂O production during …

The internal surrogate ratio method allows for the determination of an unknown cross section, such as (n,γ), relative to a better-known cross section, such as (n,f), by measuring the relative exit-channel probabilities of a surrogate reaction that proceeds through the same compound nucleus. The validity of the internal surrogate ratio method is tested by comparing the relative γ and fission exit-channel probabilities of a ²³⁶U^∗ compound nucleus, formed in the ²³⁵U(d,p) reaction, to the known ²³⁵U(n,γ) and (n,f) cross sections. A model-independent method for measuring the …

The Effect Of A Phytoplankton Maximum On The Trophic Food Chain Of The Bottlenose Dolphin (Tursiops Truncatus) In North Inlet, South Carolina., Lindsay Michael Stang

Honors Theses

Jones Creek, part of North Inlet-Winyah Bay, South Carolina, is known to have a chlorophyll a maximum that exists during low tide. The goal of this study was to determine if an increase in phytoplankton, demonstrated by chlorophyll a levels, would lead to an increase in zooplankton, fish, and bottlenose dolphins in the area. Sampling for chlorophyll a concentrations, zooplankton and dolphin densities occurred in fall of 2008. Based on the samples obtained, as chlorophyll a concentrations increased at low tide, zooplankton densities decreased. Dolphin density plots showed an increased density in Jones Creek during low tide for spring, summer, …

Effects Of A Spatially And Temporally Predictable Chlorophyll Maximum On Bottlenose Dolphin Distribution In A South Carolina Estuary, Steven W. Thornton

Honors Theses

Numerous studies have focused on the complex relationship between phytoplankton and zooplankton in estuarine environments, but few have scrutinized the effects of this connection on organisms in higher trophic levels. This study examined chlorophyll a concentrations and zooplankton densities in North Inlet, South Carolina, a site where a stable chlorophyll a maximum has been documented to exist at low tide, to determine if they influenced the distribution of resident bottlenose dolphins (Tursiops truncatus). We hypothesized that patterns of estuarine circulation in the salt marsh serve to concentrate phytoplankton and zooplankton predictably in time and space, and that these patterns influence …
