An Assessment of the Utility of Universal and Specific Genetic Markers for Opium Poppy Identification

Abstract: The proper identification of illicit plants such as Papaver somniferum L (opium poppy) is important for law enforcement agencies. The identification of opium poppy was presently tested using 10 genetic markers that are universal for all plants or specific to a few poppy plants. The genetic distances of universal markers such as nuclear internal transcribed spacer (ITS), 18S rRNA, plastid rbcL, and trnL‐trnF intergenic spacer (IGS) of 14 species included in the Papaveraceae and Fumariaceae family were acquired by sequence comparisons. Both the ITS region and trnL‐trnF IGS showed high levels of interspecific divergence. Six Papaver genera‐specific markers were developed from coding regions involved in morphine biosynthesis. Three markers (TYDC, NCS, and BBE) produced amplicons only in opium poppy, providing a presence/absence test for opium poppy, while three additional markers (CYP80B1, SAT, and COR) were genus specific. These 10 markers might be useful for the forensic DNA analysis of opium poppy.     

Ethnic identity and attitudes toward the police among African American juvenile offenders

Although there is a knowledge base regarding theoretical and empirical research on attitudes toward the police, this line of research has not fully examined the sources of such attitudes, and in particular the extent to which attitudes toward the police are influenced by ethnic identity. The present study examined the role of ethnic identity in African American adolescent offenders' perceptions of general police discrimination, direct police contact, procedural justice, and police legitimacy. Analyses showed that youth with a stronger sense of ethnic identity perceived more police discrimination but reported more positive beliefs about police legitimacy. The findings underscore the importance of considering processes that may make legal socialization experiences more salient for adolescents, and demonstrate the complex role that ethnic identity plays in relation to discrimination.     

Effect of Aging and Surface Interactions on the Diffusion of Endogenous Compounds in Latent Fingerprints Studied by Mass Spectrometry Imaging,

The ability to determine the age of fingerprints would be immeasurably beneficial in criminal investigations. We explore the possibility of determining the age of fingerprints by analyzing various compounds as they diffuse from the ridges to the valleys of fingerprints using matrix‐assisted laser desorption/ionization mass spectrometry imaging. The diffusion of two classes of endogenous fingerprint compounds, fatty acids and triacylglycerols (TGs), was studied in fresh and aged fingerprints on four surfaces. We expected higher molecular weight TGs would diffuse slower than fatty acids and allow us to determine the age of older fingerprints. However, we found interactions between endogenous compounds and the surface have a much stronger impact on diffusion than molecular weight. For example, diffusion of TGs is faster on hydrophilic plain glass or partially hydrophilic stainless steel surfaces, than on a hydrophobic Rain‐x treated surface. This result further complicates utilizing a diffusion model to age fingerprints.     

Drug Contamination of U.S. Paper Currency and Forensic Relevance of Canine Alert to Paper Currency: A Critical Review of the Scientific Literature

Several studies have reported on wide‐spread contamination of U.S. paper currency with cocaine and to a lesser extent other illicit drugs. Canines are trained and employed to search for and alert to drugs. Canine alert to currency has been used as evidence that currency has been directly involved in illicit drug trafficking to justify currency seizure and forfeiture. This assertion, particularly when the only evidence is based upon canine alert, has been challenged in the courts considering that most currency in circulation is contaminated with cocaine. Comprehensive review of the scientific literature establishes that (i) 67–100% of circulated U.S. currency is contaminated with cocaine ranging from a few nanograms to over one milligram/bill (ii) various biological and environmental parameters impact canine alert to drugs. It is concluded that canine alert to U.S. currency is not sufficiently reliable to determine that currency was directly used in an illicit drug transaction.     

The Effect of Prior Police Contact on Victimization Reporting: Results from the Police–Public Contact and National Crime Victimization Surveys

Objectives

This study explores the association between past-year face-to-face contact with the police and subsequent victimization reporting. It also examines whether this relationship depends on the type of encounter (citizen-initiated contacts, routine vehicle stops, invasive encounters associated with being a suspect), its perceived justness, or victim characteristics. Among victims who did not notify the police, the reasons behind this decision are assessed to understand the mechanisms through which police encounters are related to reporting.

Methods

This research is the first to use longitudinal data that link the 2002, 2008, and 2011 Police Public Contact Surveys to the 2002–2014 National Crime Victimization Surveys. Multivariate logistic regression is used to examine the effect of prior contact on police notification among victims of personal (N = 1073) and household (N = 11,433) crimes.

Results

Prior contact with the police has no main effect on the reporting of personal crimes; however, the negative effects of police-initiated and unjust contact are amplified for the poor and African Americans. The reporting of household crimes varies based on prior police experiences and whether they were viewed as just. Personal crime victims with invasive contact are more likely than other contact groups to attribute non-reporting to fear of reprisal.

Conclusions

Using national data tells a complex story about how race/ethnicity, poverty, and recent experiences with the police interact to shape victims’ behavior. The intricacies of these findings suggest that efforts to increase reporting may need to be multifaceted and address victims’ concerns about safety and justness.

     

Confessions of a Criminal Psychopath: an Analysis of the Robert Pickton Cell-Plant

Police interrogation methods have changed over time. While traditional techniques relied on violence and physical torture, modern techniques have shifted toward psychological coercion and manipulation. These techniques, most widely known as parts of The Reid Technique, have proven to be a powerful way to elicit confessions of guilt from suspected criminals. Authors of the Reid Technique claim that when applied correctly, their methods lead to significant increases in police confession rates. But, these techniques are not universally useful. In addition to eliciting false confessions, the Reid Technique has been less effective on psychopaths—who are self-centered, manipulative, and lack empathy. Psychopaths can be resistant to these methods, which rely on the interrogator’s ability to induce fear, anxiety, and feelings of remorse in the suspect. When confronted with a criminal psychopath, interrogators face unique challenges requiring a different approach to interrogation. To show this, we analyze the cell plant video of an undercover officer who obtained a serial murder confession from Robert Pickton by appealing to his narcissism. We conclude by offering a few additional strategies that can be used by investigators when interrogating psychopaths.     

Isolation and characterisation of a novel sildenafil analogue adulterant,desmethylpiperazinyl propoxysildenafil,in a dietary supplement

A new sildenafil analogue was detected during routine screening of dietary supplements suspected to be adulterated with an erectile dysfunction drug(s) using HPLC-DAD. The UV spectrum of this compound was highly similar to that of sildenafil and almost identical to that of desmethylpiperazinyl sildenafil. The analogue was purified by using semi-preparative HPLC and structurally elucidated by performing mass spectrometric and NMR spectroscopic experiments. The spectral data revealed that this sildenafil analogue bears an n-propoxy group instead of an ethoxy group and possesses no methylpiperazinyl moiety. The isolated compound, structure of which was further confirmed by spectral comparison with synthetic one, was thus named as desmethylpiperazinyl propoxysildenafil.     

The role of Title IV-E education and training in child protection workforce diversification

ABSTRACT

Educating, training, and diversifying the workforce are strategies that may help reduce racial/ethnic disparities that plague child protection system (CPS). Title IV-E education and training programs support the development of a specially trained, highly skilled workforce; yet, little research examining their impact on workforce diversification exists. The current study assessed the relationship between Title IV-E education and training and workforce diversity and leadership in a state system that is plagued with racial disparities using data from a statewide child welfare survey (n = 679) and existing population-level sources. Findings revealed that while children of color were disproportionately overrepresented in the CPS, professionals of color were disproportionately underrepresented (as compared to the state’s overall population and the population of children served within CPS). Title IV-E education and training programs were associated with both child protection workforce diversity and CPS leadership roles. Implications for recruitment, retention, education, and partnership are discussed.     

Older Youth in Extended Out-of-home Care

The purpose of this study is to examine the permanency experiences of older youth, age 18–21 in out-of-home placements and placement characteristics that influence age of exit from child welfare. Findings suggest a difference between age groups with more 18-year old youth exiting to emancipation than youth who exit at age 21. A higher number of spells in care and a higher number of placement changes during the last spell were associated with exit to emancipation. Additional study findings suggests that youth who leave care before the age of 21 may be more vulnerable than youth who stay through age 21. Implications for practice are discussed.     

Banking in the cloud: Part 2 – regulation of cloud as ‘outsourcing’

This paper looks at EU banks' use of public cloud computing services. It is based primarily on anonymised interviews with banks, cloud providers, advisers, and financial services regulators. The findings are presented in three parts. Part 1 explored the extent to which banks operating in the EU, including global banks, use public cloud computing services.Part 2 of this paper covers the main legal and regulatory issues that may affect banks' use of cloud services. It sets out how EU banking regulators have approached banks' use of cloud services and considers regulators' lack of cloud computing knowledge. The paper further considers how the regulation of outsourcing applies to banks' use of cloud services, including whether cloud computing constitutes “outsourcing”. It analyses the contentious issue of contractual audit rights for regulators as well as legal and practical issues around risk assessments, security, business continuity, concentration risk, bank resolution, and banking secrecy laws.Part 3 looks at the key contractual issues that arise between banks and cloud service providers, including data protection requirements, termination, service changes, and liability.All three parts of the paper can be accessed via Computer Law and Security Review's page on ScienceDirect at: http://www.sciencedirect.com/science/journal/02673649?sdc=2. The full list of sources is available via the same link and will be printed alongside the third part of the article.
