Keynote Address - When Violent Nonstate Actors Target Cultural Heritage Sites, Victor Asal

CHAR

Why would organizations attack or kill people at cultural heritage sites or destroy such sites? Using data from the Big Allied and Dangerous insurgent dataset that has data on 140 insurgent organizations from 1998-2012, and data from the Global Terrorism Database, this presentation examines the factors that make insurgent groups more likely to attack such sites or kill people at such sites. We look at the impact of organizational ideology, organizational structure and power as well as country level factors.

Mitigation, Response And Recovery, Richard Lord

Abstract: Hurricane Harvey ravaged Texas and Louisiana nearly five years after Superstorm Sandy devastated the East Coast and caused 53 deaths, destroyed or severely damaged 100,000 Long Island homes, and left an estimated $42 billion in damages across New York State.

This session will provide an overview of the disaster relief and assistance programs available under the Stafford Act, when they are triggered, and how private non-profit and cultural institutions can plan for natural hazards and take full advantage of available aid. There will also be discussion of the NYS Hazard Mitigation Plan, the Community Risk and Resiliency Act, and …

Informing Responders Using Gis And Gps, Deidre Mccarthy

CHAR

Hurricane Katrina devastated the Gulf Coast in August 2005 and created the single largest disaster for cultural resources that the United States has witnessed since the inception of the National Historic Preservation Act (NHPA) in 1966. Notably, the NHPA created the National Register of Historic Places, our nation’s catalog of important cultural resources. The NHPA also stipulates that any federal undertaking which may adversely affect National Register eligible resources be mitigated. For the Federal Emergency Management Agency (FEMA), Katrina created the largest compliance project ever under Section 106 of the NHPA.

Although causing a great deal of damage, Katrina also …

It will provide an assessment of how the climate has changed over the past Century based on a purely observational perspective. The scientific basis for anthroprogenic climate change will be explained and discussed including a description of the “greenhouse effect” and why it is important for life on this planet. We will briefly discuss global and local consequences of a warmer climate and what we need to be prepared for going forward in the coming decades.

Opening Keynote Address: Using Data To Understand Cultural Destruction, Brian I. Daniels

CHAR

Brian I. Daniels, Ph.D, Penn Cultural Heritage Center, University of Pennsylvania Museum.

Why is cultural heritage targeted in conflict? Under what circumstances? By whom? Today, due in part to the recent notorious instances of cultural destruction in the Middle East and North Africa, there is perhaps more attention among the broader scientific community than ever before about the phenomenon of cultural loss. At the same time, there are many significant data and analytical gaps. Little social science literature about cultural destruction exists and many critical questions—and avenues of research—are, as of yet, unstudied. A primary reason for this lack …

Palladium Catalyzed Cascade Reaction With N-Tosylhydrazones, Michelle Pyz, Monique Uppal

Discovery Day (formerly Post & Beyond)

Virtually all of the top pharmaceuticals sold today require the use of organic

synthesis, the development of new strategies to construct complex molecules

from readily synthesized starting materials is essential to the field

of organic chemistry and drug design. In pharmaceutical design there is a

continuing trend toward precise synthetic operations because single atoms

and single functional groups often make the difference between benefit and

harm. The overarching goal of this research project is to develop a novel,

precise, and powerful method for the construction of carbon-carbon bonds.

In particular, our research focuses on using palladium metal as catalyst in …

Use Of Soil Chemical Analysis To Detect Commercial Wildlife Game Baits, Aaron Haines, Angela Fetterolf, Meta Griffin, Tristan Conrad, Steven Kennedy

Human–Wildlife Interactions

Hunters and poachers often use commercially-available, nutrient-rich baits to attract wildlife game animals. We used atomic absorption spectroscopy and ion selective electrochemical analysis techniques to determine whether two common proprietary baits (Deer Cane and Acorn Rage) would leave detectable chemical signatures in soil (i.e., Na⁺, Cl^-, and Ca⁺²). Our goal was to evaluate low cost tests which could be replicated by wildlife conservation officers in the field. To complete the evaluation we randomly placed two commercial baits on 3 sites in The Millersville University Biological Preserve in Millersville, PA. We collected soils samples from …

Forensic State Acquisition From Internet Of Things (Fsaiot): A General Framework And Practical Approach For Iot Forensics Through Iot Device State Acquisition, Christopher S. Meffert, Devon R. Clark, Ibrahim Baggili, Frank Breitinger

Electrical & Computer Engineering and Computer Science Faculty Publications

IoT device forensics is a difficult problem given that manufactured IoT devices are not standardized, many store little to no historical data, and are always connected; making them extremely volatile. The goal of this paper was to address these challenges by presenting a primary account for a general framework and practical approach we term Forensic State Acquisition from Internet of Things (FSAIoT). We argue that by leveraging the acquisition of the state of IoT devices (e.g. if an IoT lock is open or locked), it becomes possible to paint a clear picture of events that have occurred. To this end, …

Breaking Into The Vault: Privacy, Security And Forensic Analysis Of Android Vault Applications, Xiaolu Zhang, Ibrahim Baggili, Frank Breitinger

Electrical & Computer Engineering and Computer Science Faculty Publications

In this work we share the first account for the forensic analysis, security and privacy of Android vault applications. Vaults are designed to be privacy enhancing as they allow users to hide personal data but may also be misused to hide incriminating files. Our work has already helped law enforcement in the state of Connecticut to reconstruct 66 incriminating images and 18 videos in a single criminal case. We present case studies and results from analyzing 18 Android vault applications (accounting for nearly 220 million downloads from the Google Play store) by reverse engineering them and examining the forensic artifacts …

Range Of Detection For Proteins And Dna From Fingerprints On Fired And Unfired Cartridge Casings, Stacey-Ann R. Sterling

Student Theses

Cartridges and spent cartridge casings can be probative pieces of evidence. Unfortunately due to a combination of factors such as exposure to high temperatures and initially low amounts of biological material on the surface, DNA testing so far has been mostly unsuccessful for these items. Typing other marker systems, such as protein polymorphisms, on the same biological evidence would add power of discrimination. To explore this option we developed a DNA-protein trypsin-based co-extraction method that was optimized for unfired and fired cartridges. Various sample wet and dry collection methods and multiple metal casings, such as aluminum, nickel, steel, and brass …

Optimizing A Method For Simultaneous Recovery Of Proteins And Dna From Fingerprints, Steven Kranes

Student Theses

DNA testing on touched objects is a valuable tool in forensic investigations, but DNA is usually present in low amounts, causing poor STR typing results. For touch DNA evidence, there is a clear need for additional individualization, especially for highly probative samples. This could be achieved by testing genetically variable proteins. The goal of this project was to develop a DNA/protein co-extraction method to facilitate DNA and protein testing on the same evidence item. Existing DNA extraction methods were carefully adjusted to allow for downstream mass spectrometry analysis. Initial experiments on saliva and fingerprints placed on glass suggested that trypsin …

Digital Anti-Forensics: An Implementation And Examination, Stephanie Dachs

Student Theses

The rise of computer use and technical adeptness by the general public in the last two decades are undeniable. With greater use comes a greater possibility for misuse, evidenced by today’s incredible number of crimes involving computers as well as the growth in severity from that of cyber hooliganism to cyber warfare. Although frequently utilized for privacy and security purposes, the vast range of anti-forensic techniques has contributed to the ability for hackers and criminals to obstruct computer forensic investigations.

Understanding how anti-forensics may alter important and relevant data on an electronic device will prove useful for the success and …

The Effect Of Fabric Type And Laundering Conditions On The Detection Of Semen Stains, Tyler G. Schlagetter, Claire L. Glynn

Forensic Science Publications

There has been little research into the effect of fabric type and different laundering conditions on the ability to detect semen stains on washed fabrics. This study aimed to investigate three potential factors affecting semen identification on laundered clothing: fabric type, water temperature during washing, and whether the stain was dry at the time of washing. Following laundering, semen stains on four fabric types (cotton, polyester, denim, and wool) were examined and tested with three common methods used to detect semen; screening with an alternate light source, acid phosphatase press test, and histological staining of spermatazoa. It was determined that …

Species Identification Of Necrophagous Insect Eggs Based On Amino Acid Profile Differences Revealed By Direct Analysis In Real Time-High Resolution Mass Spectrometry, Justine E. Giffen, Jennifer Y. Rosati, Cameron M. Longo, Rabi A. Musah

Publications and Research

The colonization of decomposing remains by necrophagous insects such as blow flies is of forensic importance because the progression through the various stages of insect development can be correlated to time of death. The ability to infer this information hinges on accurate determination of the fly species that are associated with the entomological evidence collected. This evidence can include eggs, larvae, pupae, and puparial casings. Determination of the egg’s identity is particularly challenging because the eggs of multiple species are morphologically very similar. We report here that the species identity of fly eggs can be determined from their chemical fingerprint …

The Advanced Spectroscopic Analysis Of Organic Gunshot Residue And Explosives, Jennifer M. Leonard

Dissertations, Theses, and Capstone Projects

With the prevalence of shooting cases and terrorist attacks/or threats that plague the current state of the criminal justice system, it is of paramount importance to be able to detect, identify and interpret the presence of gunshot residue or explosives material. This concern is seen in law enforcement agencies and the media throughout the United States and abroad.

Currently, the typical method of analyzing gunshot residue in most crime laboratories serves to identify the inorganic constituents of the primer residue, namely lead, barium and antimony. However, it is possible that the organic matter from the propellant could provide different information …

Detection Of Cathinone And Mephedrone In Plasma By Lc-Ms/Ms Using Standard Addition Quantification Technique, Theron W. Ng-A-Qui

Student Theses

Designer drugs are structural analogs of Drug Enforcement Agency (DEA) Schedule I and II substances. They are synthesized to mimic the effects of illegal drugs of abuse and to bypass the provisions of drug regulations. Despite the increased availability of designer drugs, few studies have focused on specific analytical extraction techniques for their detection and quantification in biological samples. Solid phase extraction (SPE) is the most commonly used technique for sample preparation. The purpose of this study is to evaluate the extraction efficiency of the various SPE columns with different sorbent materials for two designer drugs, cathinone and mephedrone in …
