Many real-world eyewitnesses are under the influence of alcohol either at time crime, interview, or both. Only recently has empirical research begun to examine effects on witness memory, yielding mixed results. The present study tested importance state-dependent memory in context alcohol's encoding versus retrieval a witnessed event, while simultaneously informing investigative practices: Should witnesses sober up before an interview? Participants (N = 249) were randomized control, placebo,...
The novel coronavirus SARS-CoV-2, since its initial outbreak in Wuhan, China has led to a worldwide pandemic and shut down nations. As with any outbreak, there is general strategy of detection, containment, treatment and/or cure. authors would argue that rapid efficient detection critical required successful management disease. current study explores successfully demonstrates the use canines detect COVID-19 disease exhaled breath. intended was odor on contaminated surfaces inferring recent...
Since the beginning of COVID-19 pandemic, there has been enormous interest in development measures that would allow for swift detection disease. The rapid screening and preliminary diagnosis SARS-CoV-2 infection instant identification possibly infected individuals subsequent mitigation disease spread. Herein, SARS-CoV-2-infected was explored using noninvasive sampling low-preparatory-work analytical instrumentation. Hand odor samples were obtained from SARS-CoV-2-positive -negative...
Despite growing decriminalization of Cannabis sativa (i.e., marijuana) possession throughout the United States America, there remains to be an ongoing interest in detection unlawfully possessed and transported marijuana. This issue has resulted increasing regarding generalization specification related canine More specifically, trainers have expressed concerns on whether canines can generalize odor marijuana regardless origin their training materials. research aims differentiate multiple...

The efficacy of using human volatile organic compounds (VOCs) as a form forensic evidence has been well demonstrated with canines for crime scene response, suspect identification, and location checking. Although the use scent in field is established, laboratory evaluation VOC profiles limited. This study used Headspace-Solid Phase Microextraction-Gas Chromatography-Mass Spectrometry (HS-SPME-GC-MS) to analyze hand odor samples collected from 60 individuals (30 Females 30 Males). volatiles...
Summary Intoxicated witnesses are common, making it important to understand alcohol's impact on witness accuracy and suggestibility. Participants assigned an immediate retrieval condition encoded recalled in one of the three intoxication conditions: sober control, placebo, or intoxicated. delayed were encode conditions, returned a week later, retrieve conditions. Intoxication at encoding was fully crossed with condition. mock crime video retrieved via forced‐choice test, answers already...
The spread of SARS-CoV-2, which causes the disease COVID-19, is difficult to control as some positive individuals, capable transmitting disease, can be asymptomatic. Thus, it remains critical generate noninvasive, inexpensive COVID-19 screening systems. Two such methods include detection canines and analytical instrumentation, both detect volatile organic compounds associated with SARS-CoV-2. In this study, performance trained dogs compared a noninvasive headspace-solid phase...
Abstract The action of dilute aqueous solutions representative anionic, cationic and non‐ionic wetting agents on sheet copper has been studied. Three types water have used—London tap‐water, distilled tap‐water softened by the zeolite base‐exchange process. effects varying pH from 2 to 12 temperature changes investigated. Most anion‐active examined first coated with a water‐repellent film which afforded protection metal primary secondary sodium alkyl sulphates aryl sulphonate, but not...

Abstract A widely recognized limitation in mammalian olfactory research is the lack of current methods for measuring odor availability (i.e., quantifiable amount presented and thus available olfaction) training or testing materials during behavioral operational testing. This utilized an existing technology known as Controlled Odor Mimic Permeation Systems (COMPS) to produce a reproducible, field-appropriate delivery method that can be analytically validated quantified, akin laboratory-based...
Twelve certified narcotic detection canines were tested for their ability to detect confiscated synthetic cathinones (bath salts). These then separated into two groups and imprinted on types of bath salts, ethylone alpha- pyrrolidinovalerophenone (α-PVP), over the period one month; while simultaneously documenting imprinting procedure. The newly validated by field testing found not only salt which they trained, but able other salts. procedure results are first scientifically studies these...
