Testing Models of Associations Between Depression and Parenting Self-efficacy in Mothers: A Meta-analytic Review

Numerous cross-sectional studies confirm the long-theorized association between mothers’ depression and lower parenting self-efficacy (PSE) beliefs. However, cross-sectional studies leave unanswered the direction of this association: Does depression predict PSE? Does PSE predict depression? Are both true? Does the strength of the association between depression and PSE, regardless of the direction, generalize across participant characteristics and study design features? How stable is PSE over time? And how effective are interventions at enhancing PSE? To answer these questions, we conducted a meta-analytic review of longitudinal studies. With 35 eligible studies (22,698 participants), we found support for both models: there was a significant pooled effect of both depression on PSE and of PSE on depression, with nearly identical effect sizes (d?=?????0.21 and ??0.22, respectively). The association was stronger in samples with mothers’ younger average age and studies that measured PSE among mothers relative to during pregnancy. We found a medium degree of stability in the index of PSE, d?=?0.60. Finally, the estimated pooled effect size between being in an intervention group versus control group and PSE was 0.505. Overall, we found support for (1) bidirectional associations between depression and PSE in mothers, (2) the stability of PSE over time, and (3) the strength of the relationship between PSE and depression with intervention. These results suggest the importance of continuing to develop, test, and disseminate interventions to enhance PSE. We interpret these findings in the context of both depression and low PSE having serious consequences for child outcomes and maladaptive parenting.

     

A Life Domains Perspective on Acculturation and Psychological Adjustment: A Study of Refugees from the Former Soviet Union

The study articulates a contextual approach to research on acculturation of immigrants, suggesting that the relationship between acculturation and adjustment is dependent on the cultural demands of the life domains considered. Specifically, the study investigated the mediating effects of adjustment in occupational and social life domains on the relationship between acculturation and psychological adjustment for 391 refugees from the former Soviet Union. The study used bilinear measures of acculturation to the host (American) and heritage (Russian) cultures. Using Structural Equation Modeling, the study confirmed the hypothesized relationships, such that the positive effects of American acculturation on psychological adjustment were mediated by occupational adjustment, and the effects of Russian acculturation on psychological adjustment were mediated by satisfaction with co-ethnic social support. Psychological adjustment was measured in two ways, as psychological well-being, using a measure of life satisfaction, and as symptoms of depression and anxiety, using the Hopkins symptom checklist (HSCL). Life satisfaction served as a mediator between adjustment in occupational and social domains and HSCL, suggesting that it may be an intervening variable through which environmental stress associated with immigration contributes to the development of symptoms of mental disorder.     

Heidegger,Hermeneutics and History: Undermining Jeff Malpas’s Philosophy of Place

Most works about the philosophy of Martin Heidegger either disregard Heidegger’s attachment to National Socialism or assume the ‘minimalist’ view that his attachment was a brief political aberration of no consequence for his philosophy. This paper contends that the minimalist view is not only factually wrong but also that its assumption promotes methodological errors and poor philosophy. To assess this contention we examine two important texts from one of the more fertile fields in current philosophy: Jeff Malpas’s Heidegger’s Topology: Being, Place, World (2006) and Heidegger and the Thinking of Place (2012). Malpas claims that Heidegger’s rejection of National Socialism spurred, or was concomitant with, new directions in his philosophy. These claims are wrong. The paper concludes that any work about Heidegger’s philosophy must first acknowledge and understand his enduring attachment to National Socialism.     

Philosophical perspectives on ad hoc hypotheses and the Higgs mechanism

We examine physicists’ charge of ad hocness against the Higgs mechanism in the standard model of elementary particle physics. We argue that even though this charge never rested on a clear-cut and well-entrenched definition of “ad hoc”, it is based on conceptual and methodological assumptions and principles that are well-founded elements of the scientific practice of high-energy particle physics. We further evaluate the implications of the recent discovery of a Higgs-like particle at the CERN’s Large Hadron Collider for the charge of ad hocness against the Higgs mechanism.     

Neuroscience,quantum indeterminism and the Cartesian soul

Quantum indeterminism is frequently invoked as a solution to the problem of how a disembodied soul might interact with the brain (as Descartes proposed), and is sometimes invoked in theories of libertarian free will even when they do not involve dualistic assumptions. Taking as example the Eccles–Beck model of interaction between self (or soul) and brain at the level of synaptic exocytosis, I here evaluate the plausibility of these approaches. I conclude that Heisenbergian uncertainty is too small to affect synaptic function, and that amplification by chaos or by other means does not provide a solution to this problem. Furthermore, even if Heisenbergian effects did modify brain functioning, the changes would be swamped by those due to thermal noise. Cells and neural circuits have powerful noise-resistance mechanisms, that are adequate protection against thermal noise and must therefore be more than sufficient to buffer against Heisenbergian effects. Other forms of quantum indeterminism must be considered, because these can be much greater than Heisenbergian uncertainty, but these have not so far been shown to play a role in the brain.

Feasibility and effectiveness of school-based relaxation in lowering blood pressure

Progressive muscle relaxation (PMR) is a broadly useful anxiety reduction technique that has been found to lower blood pressure (BP) in essential hypertension. The present investigation is the first to evaluate the feasibility and efficacy of wide-scale PMR instruction as a public health promotion strategy aimed at adolescents. Students (N = 1,400) in Grades 9 and 10 at two large Baltimore City public high schools underwent BP screening; those with BP persistently above the 85th percentile were randomly assigned to (a) 12 weeks daily PMR instruction provided in class for academic credit or (b) a control condition. The latter students had their BP measured at the same frequency as the PMR students and completed the PMR course during the following year. Approximately two thirds of eligible students entered and completed the study. Results demonstrated that treatment students (n = 51) enjoyed daily PMR, mastered the technique, and achieved reduced systolic BP at posttest relative to the untrained controls (n = 59). At follow-up 4 months later, group BP differences were not significant. Implications for use of PMR to promote cardiovascular health are discussed.     

The influence of mortality reminders on cultural in-group versus out-group takeaway food safety perceptions during the COVID-19 pandemic

During the early stages of the COVID-19 pandemic takeaway food orders generally increased, yet sales of Chinese and Italian food declined. At this time, news sources ran stories on the safety of cuisine from these countries, frequently juxtaposed with communications on mortality-related information related to the virus. Terror management theory suggests mortality concerns can lead people to defend against the psychological threat of death by bolstering positive evaluations of products and values of their own culture, and by disparaging products and values of other cultures. This translates to food preferences, with death reminders heightening consumption of food from one's own (vs. others’) culture. However, whether this extends to food safety perceptions has not yet been probed. In the present experimental study, we examine whether death reminders (vs. a control topic) led U.S. participants to view American takeaway food as safer to consume, relative to Chinese and Italian food. Results indicate that across conditions, American food was evaluated as safer relative to Chinese and Italian takeout. Further, American takeaway was seen as safer after mortality reminders (vs. a control topic), with no differences in safety evaluations for Chinese or Italian takeout. Results are discussed in relation to the COVID-19 pandemic.
