Emotional Dysregulation and Negative Affect Mediate the Relationship Between Maternal History of Child Maltreatment and Maternal Child Abuse Potential

Risk for committing child abuse is frequently attributed to an intergenerational “cycle of violence” through which abuse as a child increases risk for committing abuse as a parent. While this hypothesis has support, more research is needed to understand the factors that account for this pattern of risk. Given literature suggesting that adults with a history of child maltreatment have increased risk for a wide range of psychopathology, this study examined the role of two behavioral endophenotypes, emotional dysregulation and negative affect, in the association between maternal experiences of childhood maltreatment and maternal child abuse potential among 83 low-income, primarily African-American mothers of elementary school age children. Results indicate that a mother’s experience of abuse as a child predicts later risk for abusive parenting as measured by child abuse potential scores. However, our data also indicate that the relationship between maternal experience of child abuse and later child abuse potential is mediated by maternal emotional dysregulation and negative affect.     

Quantitative Determination of Cannabinoids in Cannabis and Cannabis Products Using Ultra‐High‐Performance Supercritical Fluid Chromatography and Diode Array/Mass Spectrometric Detection

Ultra‐high‐performance supercritical fluid chromatography (UHPSFC ) is an efficient analytical technique and has not been fully employed for the analysis of cannabis. Here, a novel method was developed for the analysis of 30 cannabis plant extracts and preparations using UHPSFC /PDA ‐MS . Nine of the most abundant cannabinoids, viz . CBD , ?⁸‐THC , THCV , ?⁹‐THC , CBN , CBG , THCA ‐A, CBDA , and CBGA , were quantitatively determined (RSD s < 6.9%). Unlike GC methods, no derivatization or decarboxylation was required prior to UHPSFC analysis. The UHPSFC chromatographic separation of cannabinoids displayed an inverse elution order compared to UHPLC . Combining with PDA ‐MS , this orthogonality is valuable for discrimination of cannabinoids in complex matrices. The developed method was validated, and the quantification results were compared with a standard UHPLC method. The RSD s of these two methods were within ±13.0%. Finally, chemometric analysis including principal component analysis (PCA ) and partial least squares‐discriminant analysis (PLS ‐DA ) were used to differentiate between cannabis samples.     

Potency Trends of Δ9‐THC and Other Cannabinoids in Confiscated Cannabis Preparations from 1993 to 2008*

Abstract: The University of Mississippi has a contract with the National Institute on Drug Abuse (NIDA) to carry out a variety of research activities dealing with cannabis, including the Potency Monitoring (PM) program, which provides analytical potency data on cannabis preparations confiscated in the United States. This report provides data on 46,211 samples seized and analyzed by gas chromatography‐flame ionization detection (GC‐FID) during 1993–2008. The data showed an upward trend in the mean Δ⁹‐tetrahydrocannabinol (Δ⁹‐THC) content of all confiscated cannabis preparations, which increased from 3.4% in 1993 to 8.8% in 2008. Hashish potencies did not increase consistently during this period; however, the mean yearly potency varied from 2.5–9.2% (1993–2003) to 12.0–29.3% (2004–2008). Hash oil potencies also varied considerably during this period (16.8 ± 16.3%). The increase in cannabis preparation potency is mainly due to the increase in the potency of nondomestic versus domestic samples.     

Genetic polymorphisms of 15 AmpFlSTR identifiler loci in Romani population from Northwestern Croatia

The 15 AmpFlSTR identifiler PCR loci (D8S1179, D21S11, D7S820, CSF1PO, D3S1358, TH01, D13S317, D16S539, D2S1338, D19S433, VWA, TPOX, D18S51, D5S818 and FGA) were analyzed in the sample of 100 unrelated Romani individuals from Northwestern Croatia. The agreement with HWE was confirmed for all loci. The combined power of discrimination (PD) and the combined power of exclusion (PE) for the 15 studied loci were 0.9999999999999996243580692 and 0.999990752, respectively. According to the presented data, D2S1338 proved to be the most informative marker. Population comparisons revealed significantly different F(ST) values for all analyzed population pairs.     

The EU and Multidimensional Forms of Power: Critical Moments and Change in Actorness and Power

This article introduces a framework for studying the European Union (EU) as power by focusing on what EU does rather than what EU is. Conceptualizing EU as a regional international society, EU is constituted along multidimensional lines. While a code of conduct limits internal and external practices, critical moments are important junctures for practitioners to reinterpret norms and rules, leading to the reproduction of EU as power. The practice of minority rights illustrates how a lack of intersubjectivity limits the EU’s power. It is first through practitioners’ engagement with norms and rules that new practices are established.     

Diatoms in forensic expertise of drowning--a Macedonian experience

Results obtained by examination of 22 human cases suspected for drowning, one human case of death other than drowning and several tests on laboratory rats were used as a basis for evaluation of diatom method as supportive in forensic expertise of drowning. The recovery of diatoms from various examined organs, their qualitative and quantitative composition, if properly treated without the possibility of contamination, can be a reliable proof of the time and place of drowning. The priority of organ examination (external microflora determination, lungs, brain, heart (and/or blood), stomach, liver and kidney, and finally bone marrow) is discussed and established as well as the basic future research on cases suspected of drowning, but also on non-drowned victims and laboratory animals.
