Monitoring the coefficient of variation using a variable sample size and sampling interval control chart

This article proposes a CV chart by using the variable sample size and sampling interval (VSSI) feature to improve the performance of the basic CV chart, for detecting small and moderate shifts in the CV. The proposed VSSI CV chart is designed by allowing the sample size and the sampling interval to vary. The VSSI CV chart's statistical performance is measured by using the average time to signal (ATS) and expected average time to signal (EATS) criteria and is compared with that of existing CV charts. The Markov chain approach is employed in the design of the chart.     

The Influence of Divorcing Mothers' Demeanor on Custody Evaluators' Assessment of Their Domestic Violence Allegations

A gap exists between empirical evidence demonstrating the risks posed by domestic violence (DV) and the weight that evidence is given by custody evaluators. This gap may result from common beliefs about DV that diminish or deny its seriousness, which include that mothers often make false allegations to gain advantage and that DV and high conflict are synonymous and do not require differential approaches. Using a multiple segment factorial vignette design, we systematically assessed how these beliefs influenced custody evaluators' (N = 603) recommendations and judgments of the believability of allegations. Mother's demeanor (i.e., hostile vs. pleasant) was the most consistent predictor of evaluators' recommendations and judgments of credibility. Findings have implications for providing research-based education and training for evaluators.     

Serving queer survivors of intimate partner violence through diversity,inclusion, and social justice

Queer individuals are at a heightened vulnerability to experience intimate partner violence (IPV). However, social supports for IPV survivors are often designed for cisgender and heterosexual individuals. Guided by a queer theoretical lens, this study uses interview data from seven service providers purposefully sampled through queer-serving organizations to explore how professionals can better serve queer survivors. A phenomenological analysis of the data suggests the use of three broad practice approaches: diversity, inclusion, and social justice. First, practitioners and staff discussed how they incorporated diversity by representing their clients’ backgrounds and histories. Second, they described inclusion through creating affirming spaces that recognize the unique needs of queer survivors. Last, they offered strategies related to social justice, such as implementing anti-oppressive frameworks, empowering clients beyond service provision, and being/creating advocates for social change. Together, these approaches and related strategies suggest ways to provide responsive practice for queer IPV survivors.     

‘It is like being put through a blender’: inclusive research in practice in an Australian university

Abstract

How can university-based researchers committed to a position of solidarity with, and activism alongside, people with disabilities maintain such a stance in the metric-driven environment of the modern university? How can the academy ensure there is the opportunity for people with disabilities to contribute to production of the knowledge in which they have most at stake, in a wider environment where access to basic services for people with disabilities is precarious? In this article we draw on our experience as a team of university-based and community-based researchers with and without disabilities to reflect on these questions, using a framework of reflexive solidarity to consider practical strategies for strengthening the relationship between disability activism and the academy.     

Lesbian Mothering in the Context of Intimate Partner Violence

SUMMARY

Twenty-four lesbian mothers (12 African American, 9 White, and 3 Latina) who had experienced physical abuse by a same-sex partner were interviewed. Three types of IPV were found: intimate terrorism, situational violence, and mutual violent control. Further, relationships between mothers/abusers, mothers/children, and abusers/children were examined. Regarding relationships with abusers, 71% of mothers reported lengthy sagas, 17% had worked it out, and 13% made a clean break from the abuser. Regarding relationships with their children, 48% of mothers hid the violence, 26% minimized it, and 26% openly communicated about the situation. Relationships between abusers and the mothers' children were found to be either co-parental (29%), playmate (21%), abusive (21%), or non-parental (21%). Correlations among relational and demographic variables were also examined.     

A comparison of methods to obtain active parental consent for an international student survey

Many school-based research efforts require active parental consent for student participation. Maximizing rates of consent form return and agreement is an important issue, because sample representativeness may be compromised when these rates are low. This article compares two methods for obtaining active parental consent: return of consent forms in the mail versus return by students to their classrooms. The methods were tested in a pilot study of 46 schools (1,058 students), with half of the schools randomly allocated to each of the alternative methods. A hierarchical nonlinear model of consent form return and agreement rates suggests that the student-delivered method is more successful at producing higher rates of consent form return and agreement to participate in the study, after controlling for school-level characteristics. The authors discuss the findings and their implications for other researchers engaged in school-based research with adolescents.
