The detection of hydromorphone in urine specimens with high morphine concentrations

A previous study suggested that small amounts of morphine are metabolically converted to hydromorphone. In the present study, morphine positive urine specimens obtained from a postmortem laboratory and a random urinalysis program were tested for morphine, codeine, hydromorphone, hydrocodone, oxymorphone, and oxycodone to assess the possibility that small amounts of hydromorphone are produced from the metabolism of morphine. The opioids were analyzed by gas chromatography-mass spectrometry as their respective trimethylsilyl derivatives following solid phase extraction. The limit of detection for hydromorphone was 5 ng/mL. A total of 73 morphine positive urine specimens were analyzed, with morphine concentrations ranging from 131 to 297,000 ng/mL. Hydromorphone was present at a concentration > or =5 ng/mL in 36 of these specimens at concentrations ranging from 0.02% to 12% of the morphine concentration. Hydrocodone was not detected in these specimens at the assay detection limit of 25 ng/mL. These results support earlier work suggesting that the detection of hydromorphone in urine specimens does not necessarily mean that exogenous hydromorphone or hydrocodone was used.     

Error Rates,Likelihood Ratios,and Jury Evaluation of Forensic Evidence

Forensic examiners regularly testify in criminal cases, informing the jurors whether crime scene evidence likely came from a source. In this study, we examine the impact of providing jurors with testimony further qualified by error rates and likelihood ratios, for expert testimony concerning two forensic disciplines: commonly used fingerprint comparison evidence and a novel technique involving voice comparison. Our method involved surveying mock jurors in Amazon Mechanical Turk (N = 897 laypeople) using written testimony and judicial instructions. Participants were more skeptical of voice analysis and generated fewer “guilty” decisions than for fingerprint analysis (B = 2.00, OR = 7.06, p = <0.000). We found that error rate information most strongly decreased “guilty” votes relative to no qualifying information for participants who heard fingerprint evidence (but not those that heard voice analysis evidence; B = −1.16, OR = 0.32, p = 0.007). We also found that error rates and conclusion types led to a greater decrease on “guilty” votes for fingerprint evidence than voice evidence (B = 1.44, OR = 4.23, p = 0.021). We conclude that these results suggest jurors adjust the weight placed on forensic evidence depending on their prior views about its reliability. Future research should develop testimony and judicial instructions that can better inform jurors of the strengths and limitations of forensic evidence.     

The Application of the Polyvagal Theory to High Conflict Co‐Parenting Cases

Families, litigants, lawyers, advisors embroiled in cases of complex divorce with child contact issues, manage many stressors at once. Participants involved with these types of cases are often exhausted and burned‐out from the long‐term battles of prolonged litigation. The inability to problem‐solve or even communicate effectively reflects the chaos and traumatic stress of the experience and can be seen as a hallmark of this population. When people are consistently stressed, there is a breakdown of communication skills that can create an immunity to receiving help from any direction. Often all parties involved appear to be both hyper‐alert to potential threat, and hyper‐reactive to one another: no one feels safe. Stephen Porges' Polyvagal Theory is premised on the idea that neuroception plays a key role in the nervous system's ability to assess danger in the environment. Neuroception is a neurophysiological response that does not involve cognitive processing. When cognitive processing is not involved, the result may lead to misinterpretation of, and an inability to accurately assess situations: executive functioning including rational thinking and communication skills are lost to physiological response. Rather than evaluating families and individuals involved in the aforementioned complex divorce cases through the lens of pathology, Polyvagal Theory explains their behavior as an adaptive stress reaction. Utilizing Polyvagal Theory offers a promising path to treatment with these families and diminishing the poor communication and the heightened emotion, assisting practitioners in understanding the impact of neurobiological response in managing stress and trauma. Applying Polyvagal Theory to court involved populations can help both litigants and practitioners recognize the role of the autonomic nervous system, providing the opportunity to understand, to self‐regulate, and to improve communication and decision making.

The Limits and Possibilities of Volunteering: A Framework for Explaining the Scope of Volunteer Involvement in Public and Nonprofit Organizations

Despite popular rhetoric concerning the benefits of volunteerism for public and nonprofit organizations, the use and management of volunteers to assist in the delivery of services is uneven: some organizations rely heavily on volunteer labor for this purpose, while others circumscribe volunteer contributions or eschew volunteer involvement altogether. This article introduces eight dimensions of volunteer involvement—four involving organizational decisions and four regarding volunteers’ decisions—that make up the overall scope of volunteer involvement in an organization. Based on a review of the literature, the article presents a conceptual framework and several research propositions concerning how organizational characteristics, volunteer management, and environmental factors affect the overall scope of volunteer involvement in an organization.     

Intergenerational Transmission of Convictions for Different Types of Offenses

The Cambridge Study in Delinquent Development is a prospective longitudinal survey of 411 London males from age 8 to age 56. This article compares the convictions of 343 adult sons (searched up to the median age of 29) with the convictions of their fathers up to the same age. There was significant intergenerational transmission of convictions, since 43% of the sons of convicted fathers were themselves convicted, compared with 18% of the sons of unconvicted fathers. There was significant intergenerational transmission of burglary, serious and minor theft, violence, threatening behavior, carrying an offensive weapon, and serious motoring offenses. The most important mediators between parental and child convictions were the family renting rather than owning their own home, poor parental supervision, an antiestablishment attitude of the father, parental physical punishment of the child, and separation of the son from his father. Implications for the prevention of intergenerational transmission are drawn.     

Examining the impacts of grants on senior citizen beneficiaries in Kiboga District,Uganda

This article presents the main findings of a study about the Senior Citizens Grant programme (SCG) piloted in Kiboga District, Uganda. Recognising elderly persons’ vulnerabilities and acknowledging their capabilities is essential to motivate elderly beneficiaries of social grants towards self-sustenance rather than increasing dependency on such grants. Findings indicate that indigenous support systems, such as family members and agriculture directly influenced grant expenditure patterns and thus determined the well-being of grant beneficiaries. Old age vulnerability as the main criterion for eligibility and implementation casts shadows on older persons’ capabilities needed to support their own lives, and hence impacts their well-being.     

The Developmental Unfolding of Sibling Influences on Alcohol Use over Time

Research has long demonstrated that siblings are similar in their alcohol use, however much of this work relies on cross-sectional samples or samples of adolescents alone and/or exclusive focus on older siblings’ impact on younger siblings. Using a three time-point design from early adolescence to early adulthood (M ages?=?14.9, 18.3, and 22.4 years, respectively; 55% female; 54% European ancestry, 38% Asian ancestry), we evaluated the prospective older and younger sibling influences on alcohol use across time (N?=?613 sibling pairs; 35% sisters, 26% brothers, 39% mixed-gender; average age difference?=?2.34 years; 34% full-biological siblings, 46% genetically-unrelated adopted siblings, 20% pairs where one child was the biological offspring of parents and the other was adopted). The results from both the traditional and random-intercept cross-lagged panel analyses showed that older siblings’ alcohol use predicted younger siblings’ alcohol use across each developmental transition and across a variety of sibling contexts (e.g., gender composition, age difference, genetic relatedness). On the other hand, younger siblings’ alcohol use only predicted older siblings’ alcohol use when siblings were close in age (1.5 years or less) and under conditions of high sibling companionship. These results add to a body of literature illustrating how both older and younger siblings are important socializing agents of adolescent and early adult alcohol use. Assessing or co-treating siblings for alcohol problems may be an important add-on to existing adolescent and early adult alcohol prevention and intervention programs.     

The effect of incremental benefit levels on births to AFDC recipients

We examine the relationship between fertility and incremental AFDC benefits using the 1990 Panel of the Survey of Income and Program Participation (SIPP). Estimating a logit equation for the probability of a higher-order birth among a sample of AFDC recipients, we find a positive coefficient (although statistically insignificant) on the incremental AFDC benefit level. However, we find a positive correlation between incremental benefits and fertility for several nonrecipient comparison groups which is larger than the positive correlation for AFDC recipients. This finding suggests that the previously estimated relationship between incremental benefits and fertility among AFDC recipients is largely the result of a spurious correlation. We find similar results among whites, blacks, and never-married women, but less consistent results among Hispanics and divorced or separated women. We infer from these results that family cap policies, which eliminate the incremental benefits entitled to AFDC recipients who have additional children, are not likely to result in a large reduction in the number of out-of-wedlock births to AFDC recipients.
