Worst-point suicidal plans: a dimension of suicidality predictive of past suicide attempts and eventual death by suicide

Among 440 psychiatric outpatients with current suicidal ideation, we examined the empirical distinction between the “plans” vs. “desire” dimensions of suicidality, focusing for conceptual and empirical reasons on a worst-point assessment strategy. Factor analyses were consistent with the distinction, but more importantly, among the current ideators included in this study, the worst-point “plans” dimension was the only predictor significantly related to both of two important indices, history of past attempt and eventual suicide. These findings bear on the trajectory of suicidal behavior over time, as well as inform the clinical assessment of suicidal patients.     

The Effectiveness of Victim Resistance Strategies against Stranger Child Abduction: An Analysis of Attempted and Completed Cases

Existing research, policy information, and materials intended to teach child safety assumes that certain behaviours will protect children in the event that a stranger tries to abduct them. However, there is little empirical basis for these assumptions. This paper examines the effectiveness of strategies thought to increase the likelihood that a child will be able to resist an attempted stranger child abduction event. Seventy‐eight cases of stranger child abduction that occurred in the UK between 1988 and 2014, including 25 attempted cases and 53 completed cases, were examined in order to ascertain the relative prevalence of various resistance types and to assess their effectiveness of six key resistance strategies based on whether the presence or absence affected the outcome of the abduction. Results show that direct, unequivocal verbal resistance, running away, and a composite approach where the victim runs away, calls for help, and reports the offence were highly effective means of resisting an offender, whereas physical resistance, indirect verbal resistance, and non‐resistance were not effective. Female victims were almost twice as likely to employ any kind of resistance strategy against an offender as male victims were. The implications of these findings for augmenting ways in which children are taught about safety are discussed. Copyright © 2016 John Wiley & Sons, Ltd.     

Problems for Linguistic Solutions to the Paradox of Analysis

G. E. Moore opined that the paradox of analysis might be avoided if it could be shown that sentences expressing conceptual analyses convey information not only about concepts, but also about the expressions they use. If so, "to be a brother is to be a male sibling" and "to be a brother is to be a brother" might express the same proposition, and yet not be identical in information value as the paradox suggests. How sentences might do this, Moore could not see. Many philosophers have pointed out an obvious way in which sentences might be said to convey information about the expressions they use. Some have suggested this information might be used to develop Moore's intuition and resolve the paradox of analysis. I argue that this approach fails. I present a version of the paradox of analysis that resists this sort of solution.

Bluffing and betting behavior in a simplified poker game

A pure‐strategy, simplified poker (PSP) game is proposed, where two players draw from a small and discrete number of hands. Equilibrium strategies of the game are described and an experiment is conducted where 120 subjects played the PSP against a computer, which was programmed to play either the equilibrium solution or a fictitious play (FP) learning algorithm designed to take advantage of poor play. The results show that players did not adopt the cutoff‐type strategies predicted by the equilibrium solution; rather they made considerable “errors” by: Betting when they should have checked, checking when they should have bet, and calling when they should have folded. There is no evidence that aggregate performance improved over time in either condition although considerable individual differences were observed among subjects. Behavioral learning theory (BLT) cannot easily explain these individual differences and cognitive learning theory (CLT) is introduced to explain the apparent anomalies.

Solution‐Focused Therapy as a Culturally Acknowledging Approach With American Indians

Limited literature is available applying specific theoretical orientations with American Indians. Solution‐focused therapy may be appropriate, given the client‐identified solutions, the egalitarian counselor/client relationship, the use of relationships, and the view that change is inevitable. However, adaption of scaling questions and the miracle question may be necessary. Hay una limitada cantidad de literatura disponible que aplique orientaciones teóricas específicas con indios americanos. La terapia centrada en soluciones puede ser apropiada, dadas las soluciones identificadas por los clientes, la relación igualitaria entre consejero y cliente, el uso de relaciones y la visión de que el cambio es inevitable. Sin embargo, puede que sea necesario adaptar las preguntas de escala y la pregunta del milagro.     

Critical Notices

Abstract

I argue that a practice can only be taken to be one of apparent rule following if it contains a practice of policing moves within the practice. So the existence of an apparently rule‐governed practice entails the existence of, what I call, a policing practice. I then argue that this entailment cannot be reconciled with a non‐factualist construal of the policing practice. Thus non‐factualism about the policing practice is false. Factualism about the policing practice entails realism about rules. So I conclude that we ought to be realists about rules. Finally I distinguish a position which I call ultra‐realism about rules and note that this too is a casualty of the view developed here.     

La parole au travail a-t-elle un genre ? Dialogues hôtesse de l’air/steward en résolution de problème

Few studies have investigated the way conversational work is divided between men and women in work or problem-solving contexts. This study analyzed dialogues in the workplace between 13 pairs of male and female flight attendants asked to solve a problem adapted from the Wason task. Most previous work suggests that men speak more, interrupt more, and show a greater propensity to put forward a solution. Conversely, women’s speech acts tend to be mainly of an acquiescent or questioning type. Only the hypotheses concerning interruptions, acquiescence and putting forward a solution were confirmed.     

On the relation between justification of solution method and correctness of solution in statistical problem solving

The relation between the justification of a choice of solution method and the correctness of that choice in statistical problem solving was investigated. In the first of two studies 16 subjects were asked to think aloud while solving two statistical problems. The results showed that an incorrect choice of solution method was more common when subjects did not justify their choice of solution as compared to when they justified their choice with domain-specific knowledge. Study 2 employed an experimental design. A group of 20 subjects were instructed to provide a justification for each choice of solution method, while another group of 20 subjects received no such instructions. The results showed no difference between the groups with respect to number of correct choices of solution method. A qualitative analysis of the justifications in the instructed group showed that the justifications for incorrect solution methods were more often incorrect than subjects' justifications for correct solution methods. The results in Study 2 suggested that the association found between incorrect choice of solution method and lack of justification in Study 1 was not in the first place due to a strategical deficiency on the part of the subjects but due to a lack of domain-specific knowledge.     

The analysis of structural equation models by means of derivative free nonlinear least squares

It is shown that the PAR Derivative-Free Nonlinear Regression program in BMDP can be used to fit structural equation models, producing generalized least squares estimates, standard errors, and goodness-of-fit test statistics. Covariance structure models more general than LISREL can be analyzed. The approach is particularly useful for dealing with new non-standard models and experimenting with alternate methods of estimation.
