The Epidemiology of Homicide followed by Suicide: A Systematic and Quantitative Review

This systematic review of population based studies of homicide followed by suicide was conducted to examine the associations between rates of homicide‐suicide, rates of other homicides and rates of suicide. The review analysed 64 samples, including the case of an outlier (Greenland) that were reported in 49 studies. There was a significant association between the rates of homicide‐suicide and those of other homicides in studies from the U.S.A. Outside the U.S.A. there was no clear association between homicide‐suicide and other homicide but there was modest but significant association between rates of suicide and homicide‐suicide. Homicide‐suicide appears to be closer in epidemiological terms to homicide than suicide in regions with high rates of homicide and measures to reduce homicide in these regions may also reduce homicide‐suicide.     

How does non-nutritive sucking support infant feeding?

Fifty nine premature infants participated in a randomized controlled study to determine the effectiveness of non-nutritive sucking (NNS). It was predicted that NNS would not accelerate the development of full oral feeding or early language skills as sometimes perceived in practice. However, it was predicted that using NNS as a strategy to support parents to identify and respond to early communication and oral readiness signs would increase confidence in infant management and enable quicker discharge home. Infants were aged 26–35 weeks gestation. Infants with no significant difficulties were randomly assigned to one of three groups; Group 1, NNS pre-tube feeding (n = 19); Group 2, NNS on onset of tube feeding (n = 20) and Group 3, Control (n = 20). Follow-up occurred at 6 months. There were no significant differences with number of days to full oral feeding between the groups receiving NNS and the Control group, χ²(2, n = 59) = 4.33, p = .115. A significant difference in number of days in hospital between the Control group and the other two groups was found χ² (2, n = 59) = 7.678, p = .022. Significant changes were noted with the development of more normal sucking patterns in Groups 1–3. At 6 months there were no significant differences in receptive or expressive language skills between all groups. NNS had no significant impact on the transition to full oral feeding or later language development. There was a significant difference in the number of days in hospital between the Control group and the other two groups which involved parents in identification of early communication signs. Possible reasons for this change and future directions are discussed.     

Assessing the costs and benefits of production in recognition

The production effect is a memory advantage for items studied aloud over items studied silently. Although it typically is found within subjects, here we also obtained it between subjects in a recognition task—providing new evidence that production can be an effective study strategy. Our experiment, and a set of meta-analyses, also evaluated whether the within effect reflects costs to silent items and/or benefits to aloud items. Contrary to a strong distinctiveness account, we found little evidence that aloud items show an additional within-subjects benefit. Instead, silent items suffered an additional within-subjects cost. Blocking silent and aloud items eliminated this cost, suggesting that the cost was due to mixing silent and aloud items. Our discussion focuses on implications for distinctiveness and strength accounts of the production effect and on how to implement production as an encoding strategy depending on the learner’s goals.     

Service Learning in Light of Emmanuel Levinas

Emmanuel Levinas, a twentieth century French Continental philosopher, proposed an original understanding of ethics which has serious implications for the particular activities within higher education designated as service learning and community service. First I will define service learning and community service and briefly review the theoretical and philosophical justifications typically employed to substantiate and ground these activities within higher education. Next, I will explicate key aspects from Levinas’ ethical philosophy important for reconceptualizing service learning, and discuss their significance for related concerns in higher education about language and justice. Finally, in light of these considerations, I will suggest the profound implications of a Levinasian conception of service for higher education.     

Reducing the Misinformation Effect Through Initial Testing: Take Two Tests and Recall Me in the Morning?

Initial retrieval of an event can reduce people's susceptibility to misinformation. We explored whether protective effects of initial testing could be obtained on final free recall and source‐monitoring tests. After studying six household scenes (e.g., a bathroom), participants attempted to recall items from the scenes zero, one, or two times. Immediately or after a 48‐hour delay, non‐presented items (e.g., soap and toothbrush) were exposed zero, one, or four times through a social contagion manipulation in which participants reviewed sets of recall tests ostensibly provided by other participants. A protective effect of testing emerged on a final free recall test following the delay and on a final source‐memory test regardless of delay. Taking two initial tests did not increase these protective effects. Determining whether initial testing will have protective (versus harmful) effects on memory has important practical implications for interviewing eyewitnesses. © 2015 The Authors.
