The deformation of soap film junctions by applied forces

The equilibrium configuration of soap films in a tetrahedral frame is well known, and a study is reported here of the displacement of the tetrahedral vertex formed at the junction of the Plateau borders between the films. Applying a force to this junction causes an increase in soap film area, and hence surface energy, which is modelled both theoretically and numerically. In the present work, this force is conceived as being due to the displacement of a small particle at the centre of the vertex and the energy dependence of the configuration on both the size of the particle and the magnitude of the displacement is calculated. The results underline the importance of the curvature of the films in any detailed analysis of the suspension of particles in a foam, as, for example, in the industrial process of foam flotation. The results are relevant also to problems of foam drainage and stability.     

Association between maternal sensitivity and externalizing behavior from preschool to preadolescence

Using data from the longitudinal NICHD Study of Early Child Care and Youth Development (N = 1364), this study examined the association between mothers' sensitivity and children's externalizing behavior from preschool to preadolescence. Externalizing behavior declined on average across this period with a slowing of this decline around middle childhood. Maternal sensitivity remained relatively stable on average, and there was significant variation across mothers. A decrease in maternal sensitivity from ages 3 to 11 was related to an increase in externalizing behavior from ages 4 to 12. A model-based test of the direction of the effect suggested that the association between changes in maternal sensitivity and externalizing behavior from ages 4 to 11 was driven by child effects on mothers and not vice-versa. Between late preschool age and preadolescence, the behavior problems of children appear to strongly influence the sensitive support of mothers. Practical implications were discussed in light of these findings.     

Diagnosis without treatment: responding to the War on Terror

The War on Terror has exposed deep problems within contemporary political practice. It has demonstrated the moral fragility of liberal democracy. Much critical literature on the topic is devoted to uncovering the sources of this fragility. In this paper, we accept the general thrust of much of this literature, but turn our attention to the practical upshot of the criticism. A common feature of the literature is that, when it comes to offering remedies of the problems it identifies, what is offered is ‘diagnosis without treatment’. The negation of a problem is regarded as a solution. For example, if the problem is that the USA is not acting as a good international citizen, the solution is that it begins to act as such. This is like a doctor diagnosing gout and recommending to the patient that they reduce the level of uric acid in their big toe. We argue that diagnosis without treatment is endemic in literature on the War on Terror and the ills of liberal democracy. We divide this literature into five categories and examine representative works in each. At the end of the paper, we describe what is required to avoid offering yet more diagnosis without treatment.     

Relationship of Enlightenment to the Cultural Mandate for a Biblical View of Education

The benchmark of success for many Christian schools and for Christian education, in general, is in their public-school counterparts. The very act of comparing to the standards of institutions seen as antithetical to Christianity is a major indicator of the degree to which Christian education has lost sight of its own identity and purpose. One genre of antithetical influences over Christian education is that of Enlightenment-style thinking. After an analysis of this dilemma vis-a-vis the cultural mandate, a list of highly distinctive educational goals inherent to Christian living are recommended.     

Appraisals of Fear, Helplessness, and Perceived Life-Threat During Emergent Cardiac Surgery: Relationship to Pre-surgical Depression, Trauma History, and Posttraumatic Stress

Depression and posttraumatic stress (PTS) have been linked to medical/psychological outcomes following coronary artery bypass graft (CABG) surgery. This study assessed pre-surgical trauma history, PTS, and depression; and peri-surgical appraisals of fear, helplessness, and perceived life-threat among 110 patients. All CABGs were emergent, rather than elective, surgeries. In hierarchical multiple regressions, total severity score for pre-surgical PTS predicted fear regarding the cardiac event and the CABG, and perceived life-threat regarding the cardiac event and the CABG. Pre-surgical depression predicted perceived helplessness regarding the cardiac event and the CABG, and contributed to prediction of perceived life-threat. Trauma history contributed to prediction of fear and perceived helplessness regarding surgery (but not regarding the cardiac event necessitating surgery). When posttraumatic stress disorder diagnosis (PTSD) was entered, rather than total severity of PTS, PTSD did not predict any appraisals, and depression showed stronger prediction of fear, helplessness, and perceived life-threat than did PTSD.     

Transmitting delusional beliefs in a hypnotic model of folie à deux

Folie à deux is the transference of delusional ideas from one ‘primary’ individual to one or more ‘secondary’ individuals (Lasègue & Falret, 1877). However, it is difficult to investigate experimentally because often only one patient is identified as delusional. We investigated whether hypnosis could model the experiences of the secondary in this delusion. Our primary was a confederate, who displayed two delusional beliefs and attempted to transmit them to hypnotised subjects. We manipulated the status of the confederate so that they were portrayed as either “credible” or merely “interesting”. Many high hypnotisable individuals adopted the confederate’s beliefs and confabulated evidence in support of them. Also, subjects who interacted with a credible confederate extended their delusions beyond those displayed by the confederate. We discuss the strengths and limitations of this approach and suggest ways to improve the validity of this model.     

Rethinking Early Western Buddhists: Beachcombers, ‘Going Native’ and Dissident Orientalism

Recent research on the life of U Dhammaloka and other early western Buddhists in Asia has interesting implications in relation to class, ethnicity and politics. ‘Beachcomber Buddhists’ highlight the wider situation of ‘poor whites’ in Asia—needed by empire but prone to defect from elite standards of behaviour designed to maintain imperial and racial power. ‘Going native’, exemplified by the European bhikkhu, highlights the difficulties faced by empire in policing these racial boundaries and the role of Asian agency in early ‘western’ Buddhism. Finally, such ‘dissident Orientalism’ has political implications, as with specifically Irish forms of solidarity with Asian anti-colonial movements. Within the limits imposed by the data, this article rethinks ‘early western Buddhism’ in Asia as a creative response to colonialism, shaped by Asian actors, marked by cross-racial solidarity and oriented to alternative possible futures beyond empire.     

Children's Use of Mnemonic Strategies: Variability in Response to Metamemory Training

In this study, 8- to 12-year-old children were tested to determine their level of use of a strategy for organizing lists of low-associated words into semantic groups. Then, on the basis of their scores in the strategy tests, the children were placed in either a strategic or nonstrategic group. The groups were divided into a sort-instruction training condition, in which they were told to group words so that they “go together” in some way, and a metamemory training condition, in which these instructions were supplemented by feedback, strategy reminders, and opportunities to self-test. One week later, each child's strategy use was reassessed. Children in the strategic group sorted semantically throughout training and transfer, and they showed high recall, regardless of condition. Children in the nonstrategic group showed high strategy use and recall during training, but they showed significantly more variability in recall than did the children in the strategic group. Children in the nonstrategicmetamemory condition who benefited from training were also more likely to transfer the use of the strategy than were children trained in the sort-instruction condition.
