Powers of Discrete Goodness-of-Fit Test Statistics for a Uniform Null Against a Selection of Alternative Distributions

The comparative powers of six discrete goodness-of-fit test statistics for a uniform null distribution against a variety of fully specified alternative distributions are discussed. The results suggest that the test statistics based on the empirical distribution function for ordinal data (Kolmogorov–Smirnov, Cramér–von Mises, and Anderson–Darling) are generally more powerful for trend alternative distributions. The test statistics for nominal (Pearson's chi-square and the nominal Kolmogorov–Smirnov) and circular data (Watson's test statistic) are shown to be generally more powerful for the investigated triangular (∨), flat (or platykurtic type), sharp (or leptokurtic type), and bimodal alternative distributions.     

Reviewing challenges and the future for qualitative interviewing

ABSTRACT

In this article, we consider challenges for the existence and practice of qualitative research interviews. We review key features of qualitative interviewing, in particular the debate over the radical critique of interviewing and the nature of the data it generates, to set the scene for our arguments about the current standing and future prognosis for the method of generating data and the technologies that enable this. We look at qualitative interviewing in the context of the political project of neoliberalism and the regime of austerity associated with it, and the linked turn to what is known as ‘big data’, a feature of digital technological developments in garnering data. Qualitative researchers using interview methods have been creative in working with and resisting features of neoliberal austerity pragmatically and politically, and we provide some examples. We also consider an epistemological challenge and resistance from outside of the dominant framework – interviewing in indigenous methodologies. We argue that it is the relationship between the interview as a method of data generation for research and the ways of knowing about the world, that is the epistemology that the interview-based research proceeds from, that is crucial in considering the potentials for the method’s practice.     

Failures in Child Protection: A Case Study

A case example is used to illustrate how powerful a child abuser may become; where a complex hostage-type relationship develops between family members and is then extended to include the child protection worker. One consequence of this is the increased risk of re-abuse of the children. To establish this relationship the abuser uses a number of techniques such as violence, intimidation, isolation and unpredictability. In the case presented, the three children were subjected to ongoing severe abuse, although the child protection agency had known the family for 10 years. The children often denied and hid the abuse, and the child protection workers were left largely unsupported by other professionals and often appeared to comply with the wishes of the abusing parents. © 1997 by John Wiley & Sons, Ltd.     

Is Asian ethnicity an independent risk factor for severe perineal trauma in childbirth? A systematic review of the literature

ObjectiveTo undertake a systematic review of the literature to determine whether Asian ethnicity is an independent risk factor for severe perineal trauma in childbirth.MethodOvid Medline, CINAHL, and Cochrane databases published in English were used to identify appropriate research articles from 2000 to 2010, using relevant terms in a variety of combinations. All articles included in this systematic review were assessed using the Critical Appraisal Skills Programme (CASP) ‘making sense of evidence’ tools.FindingsAsian ethnicity does not appear to be a risk factor for severe perineal trauma for women living in Asia. In contrast, studies conducted in some Western countries have identified Asian ethnicity as a risk factor for severe perineal trauma. It is unknown why (in some situations) Asian women are more vulnerable to this birth complication. The lack of an international standard definition for the term Asian further undermines clarification of this issue. Nevertheless, there is an urgent need to explore why Asian women are reported to be significantly at risk for severe perineal trauma in some Western countries.ConclusionCurrent research on this topic is confusing and conflicting. Further research is urgently required to explore why Asian women are at risk for severe perineal trauma in some birth settings.     

Editorial

The UK Government agencies have an interest in making greater use of administrative data. This paper discusses the methodological challenges of using administrative data held by the Department for Work and Pensions (DWP) for constructing an alternative sampling frame for the Family Resources Survey (FRS) and for replacing income data collected in the FRS. The analysis shows that administrative data would provide a good basis for sampling the FRS by linking to socio-demographic data held administratively, which would be advantageous for sampling specific sub-populations (e.g. types of benefit recipients or households with children). Sampling using administrative data also potentially offers more representative population sampling by including some addresses currently excluded from the small users Postcode Address File (PAF) but which are important to DWP, such as people living in care homes. However, comparing FRS questions and income data held administratively, suggests little overlap. Therefore, limited gains may be realised from shortening the length of the FRS by using income data from administrative sources.     

Parental spanking and subsequent risk for child aggression in father-involved families of young children

This study examined separate and combined maternal and paternal use of spanking with children at age 3 and children's subsequent aggressive behavior at age 5. The sample was derived from a birth cohort study and included families (n = 923) in which both parents lived with the child at age 3. In this sample, 44% of 3-year-olds were spanked 2 times or more in the past month by either parent or both parents. In separate analyses, being spanked more than twice in the prior month at age 3, by either mother or father, was associated with increased child aggression at 5 years. In combined analyses, there was a dose–response association; the greatest risk for child aggression was reported when both parents spanked more than twice in the prior month (adjusted odds ratio: 2.01; [confidence interval: 1.03–3.94]). Violence prevention initiatives should target and engage mothers and fathers in anticipatory guidance efforts aimed at increasing the use of effective and non-aggressive child discipline techniques and reducing the use of spanking.
