The purpose of this paper is to provide an input-output life cycle assessment model to estimate the carbon footprint of US manufacturing sectors. To achieve this, the paper sets out the following objectives: develop a time series carbon footprint estimation model for US manufacturing sectors; analyze the annual and cumulative carbon footprint; analyze and identify the most carbon emitting and carbon intensive manufacturing industries in the last four decades; and analyze the supply chains of US manufacturing industries to help identify the most critical carbon emitting industries.

This paper studies the relationship between housing prices, stock prices, interest rates and aggregate output in the U.S. using monthly data from 1993 to 2014. Evidence from causality tests and a variance decomposition procedure suggest that stock prices have a much larger effect on aggregate output in the U.S. economy than do either housing prices or interest rates. Instead, the wealth effect created by changes in stock prices has a relatively large impact on U.S. aggregate output. Separate estimations and variance decompositions for the sample periods 1993 - 2001, 2002 – 2008 and 2009 – 2014 show that the impact …

Public health is potentially at risk after a contaminant of concern (COC) is released into the ecosphere. The extent of contamination depends on numerous factors; modeling a contaminant’s dynamic behavior is challenging, given the multitude of relevant parameters and the fluid nature of processes involved. For example, weather events (e.g., wet or dry periods) may affect the mass depletion and the fate and transport of COCs, and hence, the risk assessment of current and potential future exposures. Thus, to give realistic estimates for potential risks, a contaminant’s dynamic behavior must be taken into account in decision-making processes. In this paper, …

Programmable Logic Controllers (PLCs) are common components implemented across many industries such as manufacturing, water management, travel, aerospace and hospitals to name a few. Given their broad deployment in critical systems, they became and still are a common target for cyber attacks; the most prominent one being Stuxnet. Often PLCs (especially older ones) are only protected by an outer line of defense (e.g., a firewall) but once an attacker gains access to the system or the network, there might not be any other defense layers. In this scenario, a forensic investigator should not rely on the existing software as it …

This paper targets two main goals. First, we want to provide an overview of available datasets that can be used by researchers and where to find them. Second, we want to stress the importance of sharing datasets to allow researchers to replicate results and improve the state of the art. To answer the first goal, we analyzed 715 peer-reviewed research articles from 2010 to 2015 with focus and relevance to digital forensics to see what datasets are available and focused on three major aspects: (1) the origin of the dataset (e.g., real world vs. synthetic), (2) if datasets were released …
Reasons For Gaps In Crime Reporting: The Case Of White-Collar Criminals Investigated By Private Fraud Examiners In Norway, Petter Gottschalk, Maria Tcherni-Buzzeo
Reasons For Gaps In Crime Reporting: The Case Of White-Collar Criminals Investigated By Private Fraud Examiners In Norway, Petter Gottschalk, Maria Tcherni-Buzzeo
Criminal Justice Faculty Publications
A private investigation is an examination of facts, sequence of events, causes for deviance, and responsibilities for negative incidents. Recent years have seen an increasing use of private internal investigations in terms of the assessment of financial irregularities. The form of inquiry aims to uncover vulnerabilities to unrestricted opportunities, failing internal controls, abuse of position, and any financial misconduct such as corruption, fraud, embezzlement, theft, manipulation, tax evasion and other forms of economic crime. When fraud examiners discover evidence of white-collar crime, they almost always leave it to their clients to decide whether or not to report crime to the …

This research was undertaken to study the implementation and adoption of Lean management practices across several industrial sectors in Pakistan. A total of 100 companies were surveyed across five industries. The objective was to determine if there was disparity in the implementation of Lean practices and to provide a yardstick to measure that disparity. Furthermore, this study identified Lean management best practices across several industries in Pakistan, thus providing benchmarks for other industrial sectors. The data collected was analysed using various descriptive statistical methods. The results indicated robust adoption and implementation of Lean practices in Pakistani industry, though there were …

Background This study explored the health philosophy and practice orientation of RDNs in the United States. Methods A randomly selected group of RDNs were recruited to take an online survey using a reduced version of Integrative Medicine practice (IM-30). Confirmatory factor analysis, analyses of variance, and non-parametric tests were used to investigate the relationships between dietetic professionals' personal health philosophy, lifestyle, and orientation to Integrative Medicine. Results Overall construct validity of the IM-26 scale was demonstrated by Cronbach's α with reliabilities ranging from 0.766 to 0.89. Results from chi-square test of goodness-of-fit test (N = 477, χ2 = 228.72, p …

We show that a compact almost Ricci soliton whose soliton vector field is divergence-free is Einstein and its soliton vector field is Killing. Next we show that an almost Ricci soliton reduces to Ricci soliton if and only if the associated vector field is geodesic. Finally, we prove that a contact metric manifold is K-contact if and only if its Reeb vector field is geodesic.

Purpose: This paper focuses on tracing GHG emissions across the supply chain industries associated with the U.S. residential, commercial and industrial building stock and provides optimized GHG reduction policy plans for sustainable development.
Design/Methodology/Approach: A two-step hierarchical approach is developed. Firstly, Economic Input Output-based Life Cycle Assessment (EIO-LCA) is utilized to quantify the GHG emissions associated with the U.S. residential, commercial and industrial building stock. Secondly, a mixed integer linear programming (MILP) based optimization framework is developed to identify the optimal GHG emissions’ reduction (%) for each industry across the supply chain network of the U.S. economy.
Findings: The results …

The DJI Phantom III drone has already been used for malicious activities (to drop bombs, remote surveillance and plane watching) in 2016 and 2017. At the time of writing, DJI was the drone manufacturer with the largest market share. Our work presents the primary thorough forensic analysis of the DJI Phantom III drone, and the primary account for proprietary file structures stored by the examined drone. It also presents the forensically sound open source tool DRone Open source Parser (DROP) that parses proprietary DAT files extracted from the drone's nonvolatile internal storage. These DAT files are encrypted and encoded. The …

Raman spectroscopy is fast becoming a popular technique in the forensic science discipline, and more recently its focus has turned to biological samples. This study reveals the ability of Raman spectroscopy to identify some forensically relevant body fluids, both individually and within mixed samples, that can be crucial in some forensic investigations. This study also further demonstrates the capabilities of Raman as a means for human blood identification in simulated crime scene samples to include bloodstains on a variety of fabrics, at varying dilutions, following laundering, and with the use of various blood-enhancement reagents. The impact of washing and blood-enhancement …
