A New Pathway To Enhance The Nuclear Security Regime, Francesca Giovannini Dec 2016

A New Pathway To Enhance The Nuclear Security Regime, Francesca Giovannini

International Journal of Nuclear Security

The paper investigates the approach used by a new set of regional institutions, the Disaster Preparedness and Risk Management Organizations (DPRMOs), in strengthening regional governance and cooperation. It also inquires in what ways these new institutions might indirectly contribute to the establishment of a more cohesive global nuclear security framework. More specifically, through the examination of the case of Southeast Asia, the paper argues that these institutions, albeit without a specific and direct mandate to operate in the nuclear security domain, are fundamentally strengthening states’ capacity to assess risks and threats and to map vulnerabilities in timely fashion. They are …

Modern Advancements In Post-Detonation Nuclear Forensic Analysis, S. Adam Stratz, Jonathan A. Gill, John D. Auxier Ii, Howard L. Hall

International Journal of Nuclear Security

Deterring nuclear terrorism is a critical national asset to support the preclusion of non-state actors from initiating a nuclear attack on the United States. Successful attribution of a detonated nuclear weapon allows for timely responsive measures that prove essential in the period following a nuclear event. In conjunction with intelligence and law enforcement evidence, the technical nuclear forensics (TNF) post-detonation community supports this mission through the development and advancement of expertise to characterize weapon debris through a rapid, accurate, and detailed approach. Though the TNF field is young, numerous strides have been made in recent years toward a more robust …

Modified Fault Tree Method For Vulnerability Analysis Of Nuclear Medicine Facility Security System Case Study: Radiotherapy Facility, Sardjito General Hospital, Haryono Budi Santosa

International Journal of Nuclear Security

Assessing the vulnerability of physical protection systems (PPS) in nuclear medicine facilities is needed to prevent a security incident that could lead to the malicious use of nuclear material. Theft and sabotage of nuclear materials is becoming globally recognized. The current methods of assessing vulnerability tend to be oriented toward complex nuclear security; consequently, it is excessive to use such methods in simple facilities (i.e., radiotherapy facilities in hospitals).

The fault tree analysis is a method to assess vulnerability for a simple nuclear facility. The method’s primary events (i.e., basic events and undeveloped events) are able to accommodate fault causes …

Neuropsychological Effects Of Placebo Stimulants In College Students, Samantha Jayne Lookatch Dec 2016

Neuropsychological Effects Of Placebo Stimulants In College Students, Samantha Jayne Lookatch

Doctoral Dissertations

The past 15 years has seen increases in the nonmedical use of prescription stimulants (NMUPS; e.g., Adderall, Ritalin, Focalin) across college students with rates reported between 6 and 34 percent. Many underestimate or ignore the serious side effects associated with stimulant medication. Furthermore, stimulant medications used to treat ADHD are classified as Schedule II drugs by the Drug Enforcement Agency as they provide beneficial outcomes when used as a prescription medication, but have a high potential risk for abuse, rendering the diversion and unprescribed use illegal. There is also the ethical dilemma that arises when students have access to prescription …

Reconstructing Late Holocene Fire, Agriculture, And Climate From Sediment Records In Costa Rica And The Dominican Republic, Erik Nicholas Johanson Dec 2016

Reconstructing Late Holocene Fire, Agriculture, And Climate From Sediment Records In Costa Rica And The Dominican Republic, Erik Nicholas Johanson

Doctoral Dissertations

We use multiple proxies from sediment cores to identify periods of climate stress during the late Holocene across the circum-Caribbean region and to determine how fire activity and signals of Pre-Columbian agriculture coincide with these arid periods. We examine evidence of aridity from stable carbon isotope ratios and shifts in elemental composition, along with pollen and microscopic charcoal, at Bao Bog in the highlands of Hispaniola. We infer two major periods of aridity (3600–2300 and 1040–850 cal yr BP), with the later period associated with the late phase of the Terminal Classic Drought. A third, less marked interval of aridity …
