Johnson's Differentiation Theory: Is It Really Empirically Supported?

Michael Johnson's differentiation of “types” of domestic violence has had a significant impact on courts and providers, in part because of its claim to an empirical basis. Unfortunately, the label “situational couple violence” has already been used by judges and evaluators to minimize abuse claims in custody cases. Johnson's repeated assertion that SCV is the most common form of domestic violence reinforces the marginalizing of domestic violence. But what do his data actually show? Here Professor Meier takes a close look at the research Johnson relies on and finds that it fails to prove his thesis. Rather, the data suggest that Johnson has it exactly backward: Control-based abuse is probably far more common than “situational” domestic violence.     

Improved Estimates and Confidence Intervals for Regenerative Simulation

In regenerative simulation, one frequently requires an estimate or a confidence interval for the ratio of the means of the two components of a certain bivariate random quantity. Estimation of this ratio has been studied by many authors and most recently by Asmussen and Rydén(2010 Asmussen, S., Rydén, T. (2010). A note on skewness in regenerative simulation. Communications in Statistics—Simulation and Computation 40: 45–57.[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]). Here, we propose an estimate that performs better than the best of the known estimates. Our estimate is also lot simpler than the best known estimate.     

Pleas,priors, and prison: Racial/ethnic differences in sentencing

Final case disposition and sentencing decisions for whites, blacks, and Chicanos are modeled with event-history data from the State of California. Dynamic analyses are used to link processing models and theories. The three-way interaction of (1) pleading guilty × (2) racial/ethnic group membership × (3) the extent of prior court experience on rates of moving through the legal system is assessed, controlling for other legitimate and nonlegitimate influences. In a jurisdiction handling large numbers of defendants representing diverse racial/ethnic and cultural groups under determinate sentencing, the timing of legal processing is shown to be critical. Results demonstrate that pleading guilty increases the speed of processing most when sentences do not involve incarceration, though this effect is not found for second or later arrests of Chicanos. Generally, theories of resource mobilization receive greater support than cultural stereotyping.

Online measures of looking and learning in infancy

Infants in laboratory settings look longer at events that violate their expectations, learn better about objects that behave unexpectedly, and match utterances to the objects that likely elicited them. The paradigms revealing these behaviors have become cornerstones of research on preverbal cognition. However, little is known about whether these canonical behaviors are observed outside laboratory settings. Here, we describe a series of online protocols that replicate classic laboratory findings, detailing our methods throughout. In Experiment 1a, 15-month-old infants (N = 24) looked longer at an online support event culminating in an Unexpected outcome (i.e., appearing to defy gravity) than an Expected outcome. Infants did not, however, show the same success with an online solidity event. In Experiment 1b, 15-month-old infants (N = 24) showed surprise-induced learning following online events—they were better able to learn a novel object's label when the object had behaved unexpectedly compared to when it behaved expectedly. Finally, in Experiment 2, 16-month-old infants (N = 20) who heard a valenced utterance (“Yum!”) showed preferential looking to the object most likely to have generated that utterance. Together, these results suggest that, with some adjustments, online testing is a feasible and promising approach for infant cognition research.

Conflicting contexts: Midwives’ interpretation of childbirth through photo elicitation

IntroductionThis study seeks to explore midwives’ perceptions about childbirth and in particular their beliefs about normality and risk. In the current climate of increasing interventions during labour, it is important to understand the thought processes that impact on midwifery care in order to examine whether these beliefs influence midwifery clinical decision-making.Method12 Midwives who worked in a variety of metropolitan hospitals in Sydney, Australia were interviewed about how they care for women during labour. The study utilised an inductive qualitative design using photo elicitation during the interview process.ResultsSix themes emerged from the data that clearly indicated midwives felt challenged by working in a system dominated by an obstetric model of care that undermined midwifery autonomy in maintaining normal birth. These themes were: desiring normal, scanning the environment, constructing the context, navigating the way, relinquishing desire and reflecting on reality. Most midwives felt they were unable to practice in the manner they were philosophically aligned to, that is, promoting normal birth, as the medical model restricted their practice.DiscussionThe polarised views of childbirth held by midwives and obstetricians do little to enhance normal birth outcomes. Midwives in this study expressed frustration that they were unable to practice midwifery in a way that reflected their belief in normal birth. This, they cite is a result of the oppressive obstetric model prevalent in maternity care facilities in Sydney and the over use of technological interventions during childbirth.     

Impact of having a high-risk pregnancy on future postpartum contraceptive method choice

BackgroundTo compare the knowledge and preference of preconceptional contraception to future postpartum contraceptive method choice in high-risk pregnancies.Research questionDoes a high-risk pregnancy condition affect future postpartum contraceptive method choice?MethodWomen hospitalised at the High Risk Pregnancy unit of a tertiary research and training hospital were asked to complete a self-reported questionnaire that included demographic characteristics, presence of unintended pregnancy, contraceptive method of choice before the current pregnancy, plans for contraceptive use following delivery and requests for any contraceptive counselling in the postpartum period.FindingsA total of 655 pregnant women were recruited. The mean age, gravidity and parity of the women were 27.48 ± 6.25 years, 2.81 ± 2.15 and 1.40 ± 1.77, respectively. High-risk pregnancy indications included 207 (31.6%) maternal, 396 (60.5%) foetal and 52 (7.9%) uterine factors. All postpartum contraceptive choices except for combined oral contraceptives (COCs) usage were significantly different from preconceptional contraceptive preferences (p < 0.001). High-risk pregnancy indications, future child bearing, ideal number of children, income and education levels were the most important factors influencing postpartum contraceptive choices. While the leading contraceptive method in the postpartum period was long-acting reversible contraceptive methods (non-hormonal copper intrauterine device Cu-IUD, the levonorgestrel-releasing intrauterine system (LNG-IUS) (40%), the least preferred method was COCs use (5.2%) and preference of COCs use showed no difference between the preconceptional and postpartum periods (p = 0.202). Overall 73.7% of the women wanted to receive contraceptive counselling before their discharge.ConclusionA high-risk pregnancy condition may change the opinion and preference of contraceptive use, and also seems to affect the awareness of family planning methods.
