Increased sensitivity for amplified STR alleles on capillary sequencers with BigDye XTerminator™

Free fluorescent dyes from PCR primers or amplification products can interfere with the interpretation of STR alleles in an electropherograph especially when the profiles have a low signal intensity. These artefacts can be removed by using a simple procedure based on BigDye^® XTerminator™. This procedure requires limited amounts of PCR product, allows to do several loadings on a capillary sequencer starting from the same purified PCR product and also increases the sensitivity for detection of less amplified loci.     

The relationship of stress, impulsivity, and beliefs to drug use severity in a sample of women prison inmates

There is a paucity of research examining substance abuse issues among women prisoners. This study explored relationships between perceived stress, impulsivity, and beliefs in the efficacy of drugs as these variables pertain to self-reported drug use severity. Women prisoners (N = 100) participated in structured face-to-face interviews based on established research instruments. Although there was no significant correlation between demographic characteristics and substance use severity, positive relationships were found between substance use severity, perceived stress, impulsivity, and beliefs. A multiple linear model was estimated regressing drug use severity on beliefs, impulsivity, and perceived stress. Only the measures of beliefs and impulsivity were significant correlates of drug use severity. Implications are discussed for prison substance abuse programming and future research.

Reflecting on Social Movement Unionism in Hong Kong: The Case of the Dockworkers’ Strike in 2013

By analysing the 2013 Hong Kong dockworkers’ strike, this article explores how workers, precariously situated in the world’s freest economy, fight for decent wages with the support of civil society. It is argued that the trade union movement in Hong Kong, a Special Administration Region of the People’s Republic of China, is a typical example of social movement unionism. It suggests that the rise of social movement unionism in Hong Kong was a practical strategy of social activists to support labour rights under the specific context of vulnerable structural power, weak institutional power, failed political unionism and a vibrant civil society. Social movement unionism has a “double-edged sword” effect on workers’ power: on the one hand, it has the potential to create societal power and strengthen associational power; on the other hand, it may compromise workers’ militancy and the possibility of stronger workplace bargaining power during workers’ struggle.     

Florence Nightingale a Hundred Years on: who she was and what she was not

This article reviews Florence Nightingale's work 100 years after her death, based on surviving writing compiled for The Collected Works of Florence Nightingale. Described are her founding of a new profession for women, based on patient care, her pioneering work in statistics and data analysis and her bold reform of the workhouse infirmaries. A section on historiography focuses on the negative impact of F. B. Smith's attack on Nightingale in 1982 and Monica Baly's progressively more negative interpretations from the 1970s to her death in 1998. Note is made of future research opportunities .     

Comparison of 12-Year-Old Children with Prenatal Exposure to Cocaine and Non-Exposed Controls on Caregiver Ratings of Executive Function

Differences in caregiver reported executive function in 12-year-old children who were prenatally exposed to cocaine (PCE) compared to children who were not prenatally exposed to cocaine (NCE) were assessed. One hundred and sixty-nine PCE and 169 NCE, primarily African-American, low socioeconomic status children participated in a prospective longitudinal study. The Behavior Rating Inventory of Executive Function (BRIEF) Parent Form was administered. Two broadband BRIEF scores (Behavioral Regulation Index (BRI) and Metacognition Index (MI)) and a summary Global Executive Composite (GEC) were computed. Multiple and logistic regression analyses were used to assess the effects of amount of PCE on executive function, controlling for covariates including caregiver (rater) psychological distress, child’s gender and other prenatal drug exposure variables. After adjustment for covariates, amount of PCE was associated with the GEC and two MI subscales, Plan/Organize and Monitor, with heavier exposure associated with more problems of executive function. An amount of PCE by gender interaction revealed amount of PCE effects in other remaining subscales of the MI (Initiate, Working Memory, and Organization of Materials) only among girls. Head circumference did not mediate the effects of cocaine on outcomes. Higher current caregiver psychological distress levels were independently associated with poorer ratings on the executive function scales. Assessment and targeted interventions to improve metacognitive processes are recommended for girls who were prenatally exposed to cocaine.
