Solid-phase microextraction for the determination of cocaine and cocaethylene in human hair by gas chromatography-mass spectrometry

A method for the simultaneous determination of cocaine (COC) and cocaethylene (CE) in human hair was developed, using solid-phase microextraction (SPME) and gas chromatography-mass spectrometry (GC-MS) as analytical technique to identify and quantify the drugs. Selected ion monitoring (SIM) mode was used to obtain higher sensitivity. The deuterated-labeled analogues were used as internal standards. The detector response was linear for the drugs studied over the range 0.4-15 ng/mg, with correlation coefficients higher than 0.995. The coefficients of variation oscillated between 0.65% and 14.18% and the accuracy was in the range from 0.73% to 11.20%. The limits of quantitation and detection were found to be acceptable. Finally, this method was applied to 15 hair samples from cocaine users, obtaining positive results in all cases. The mean concentrations were 5.39 ng/mg (range: 0.43-8.98 ng/mg) for cocaine and 1.11 ng/mg (range: 0.42-2.23 ng/mg) for cocaethylene.     

Dual Arrest and Other Unintended Consequences of Mandatory Arrest in New York City: A Brief Report

In jurisdictions across the United States, the mandated arrest of individuals perpetrating domestic violence crimes termed “mandatory arrest” or “pro-arrest” policies has become a key policy solution to the issue of domestic violence. The purposes of the policies are to standardize the police response to, and increase the number of, arrests stemming from domestic violence incidents by removing or reducing police discretion to arrest. In 1994, the New York state legislature passed the Family Protection and Domestic Violence Intervention Act, which contained provisions enacting a mandatory arrest statute. Using information from 183 callers to a telephone helpline for victims of domestic violence, we describe four unintended consequences of the policy: “unwanted,” “dual,” “retaliatory,” and “no” arrest. Bi- and multivariate analyses are used to identify victim and perpetrator sociodemographic, situational, and legal factors associated with each arrest type. Results are discussed in the context of the effects of mandatory arrest policies and minimizing problems associated with it in the future.

History and Thought in China’s Traditions

The recent turn to China??s traditions has the potential to correct for the Eurocentrism of Political Science theories. Nevertheless, the overwhelming emphasis on political thought, especially Confucianism, may have its drawbacks. This article suggests that political scientists who are interested in building theories and drawing policy implications should study the verifiable, i.e., history. Unless the purpose is to study philosophy for its own sake, political scientists should study political thought in practice, rather than political thought divorced from history. This article first discusses why it is important to examine history beyond thought. It then analyzes why scholars should not conflate political thought with historical practice. It anchors the analysis with a high-profile recent book on ancient Chinese thought.     

Alternate Paths to Power? Women's Political Representation in Nicaragua

Political alternate positions (otherwise known as substitutes) can have important effects on women's abilities to enter politics. Using the case of Nicaragua, this study assesses whether these alternate positions are being used to increase women's political representation or as a tool to undermine women's advancement into positions of power. By examining patterns of women's representation as candidates in the 1996, 2001, and 2006 elections for the National Assembly and as elected officeholders (as both alternates for those assembly members and titleholders), the article analyzes how various political parties are utilizing these alternate positions. Contrary to the conventional wisdom, this study finds no evidence that these alternate positions are used to undermine women's political progress.     

The suitability of using domestic pigs (Sus spp.) as human proxies in the geophysical detection of clandestine graves

Research in many forensic science fields commonly uses domestic pigs (Sus spp.) as proxies for human remains, due to their physiological and anatomical similarities, as well as being more readily available. Unfortunately, previous research, especially that which compares the decompositional process, has shown that pigs are not appropriate proxies for humans. To date, there has not been any published research that specifically addresses whether domestic pigs are adequate human proxies for the geophysical detection of clandestine graves. As such, the aim of this paper was to compare the geophysical responses of pig cadavers and human donor graves, in order to determine if pigs can indeed be used as adequate human proxies. To accomplish this, ground penetrating radar (GPR) and electrical resistivity tomography (ERT) responses on single and multiple pig cadaver graves were compared to single and multiple human donor graves, all of which are in known locations within the same geological environment. The results showed that under field conditions, both GPR and ERT were successful at observing human and pig burials, with no obvious differences between the detected geophysical responses. The results also showed that there were no differences in the geophysical responses of those who were clothed and unclothed. The similarity of the responses may reflect that the geophysical techniques can detect graves despite what their contents are. The study implications suggest that experimental studies in other soil and climate conditions can be easily replicated, benefiting law enforcement with missing persons cases.     

Portion size matters: Carrion ecology lessons for medicolegal death investigations—A study in Cape Town,South Africa

Forensic taphonomic studies are regionally specific and improve time since death estimates for medico-legal casework. Within forensic taphonomy and carrion ecology, vertebrate scavengers are under-researched with many studies conducted using multiple, unclothed carcasses. This is a forensically unrealistic experimental design choice with unknown impact. The effect of variation in carrion biomass on the decomposition ecosystem, particularly where vertebrate scavengers are concerned, requires clarification. To assess the effect of carrion biomass load on vertebrate scavenging and decomposition rate, seasonal baseline data for single, clothed ~60 kg porcine carcasses were compared to clothed multiple-carcass deployments, in a forensically relevant habitat of Cape Town, South Africa. Decomposition was tracked via weight loss and bloat progression and scavenging activity via motion-activated cameras. The single carcasses decayed more quickly, particularly during the cooler, wetter winter, strongly correlated with concentrated Cape gray mongoose (Galerella pulverulenta) scavenging activity. On average and across seasons, the single carcasses lost 68% of their mass by day 32 (567 accumulated degree days [ADD]), compared to 80 days (1477 ADD) for multi-carcass deployments. The single carcasses experienced substantially more scavenging activity, with longer visits by single and multiple mongooses, totaling 53 h on average compared to 20 h for the multi-carcass deployments. These differences in scavenging activity and decay rate demonstrate the impact of carrion biomass load on decomposition for forensic taphonomy research. These findings need corroboration. However, forensic realism requires consideration in taphonomic study design. Longitudinally examining many single carcasses may produce more forensically accurate, locally appropriate, and usable results.     

Turning Back the Clock? Violence against Women and the Trump Administration

ABSTRACT

The Trump Administration has engaged in a systematic rolling back of protections, regulations, and a host of other social safety net programs for vulnerable people, leaving over half of the population in dismay while others celebrate archaic triumphs. In this context, our focus is limited to the Trump Administration’s efforts—through law and words—to turn back the clock for women. We examine the reinforcement of overt forms of inequality rooted in patriarchy through domestic law as well as Trump’s misogynistic attitude and language toward women. Given that his words hold a greater significance now that he is President of the United States, he has a “gold-plated” pulpit to share and spread his misogynistic hostile rhetoric and propaganda: anti-women objectification, devaluing, and demonization through hegemonic “wordfare” while feeding and fueling sexism across the country. We conclude by suggesting that Trump’s rhetoric and that of other leading political figures are contributing to a darker time for those not in the white elite heteronormative order with short and long term implications and harm. We caution that the current dangers posed by these attacks are entering us into an endemic misogynist normal: retroactively moving the Country back in time at a dangerous speed.     

Risk Factors and Pathways to Imprisonment among Incarcerated Women in Victoria, 1860–1920

Criminological studies have found that men’s and women’s pathways to imprisonment differ, with risk factors such as substance abuse, mental illness, socioeconomic circumstances and past victimisation more strongly associated with female prisoners. However, limited quantitative or longitudinal research exists on how the risk factors associated with female offending may have shifted over time. This article investigates the criminal careers and pathways to imprisonment of 6,042 women incarcerated in Victoria between 1860 and 1920, and the risk factors associated with subsequent recidivism. The findings suggest that, while many of today’s risk factors were present historically, there have been notable shifts across time.
