The Dodo Manifesto

In this article I review the psychotherapy outcomes literature as it pertains to the Dodo hypothesis. This is the proposition that the effects of psychotherapy are due to common factors rather than specific techniques. A variety of sources provide substantial empirical support for the Dodo hypothesis. I conclude that CBT and medication do not appear to be any better than other methodologies for the treatment of psychological distress. I look at some of the criticisms of the Dodo hypothesis. I suggest that the major themes that emerge from the literature as it stands are conclusions that would be immediately obvious to most clinicians. Further, the utility of specific techniques has not been ruled out, due to some serious conceptual flaws in efficacy trials. I suggest that there are a number of ways for family therapists to survive in an evidence‐based world. One is to point out to champions of evidence‐based practice just how flimsy their claims are. Another would be to advocate for pluralism and to practise and conduct research under the aegis of a contextual philosophy.     

Single Parent Adoptions: A Review

Single parent adoption is a new phenomenon in North America. Social workers will have to deal with this adoption issue at an increasing rate. This paper reviews the findings of existing studies relating to one-parent adoptions.     

WHY HOLD-UPS OCCUR: THE SELF-ENFORCING RANGE OF CONTRACTUAL RELATIONSHIPS

Court enforcement and private enforcement are not alternative contract enforcement mechanisms, but are used jointly by transactors to define the self-enforcing range of a contractual relationship. Within this framework contract terms economize on the limited amounts of private enforcement capital possessed by transactors, either by directly controlling transactor behavior or by shifting private enforcement capital between transactors to coincide with likely future market conditions. Hold-ups occur when market conditions change sufficiently to place the relationship outside the self-enforcing range. This probabilistic view of hold-ups is contrasted with opportunism more generally and with moral hazard behavior.     

Scrambled randomized response methods for obtaining sensitive quantitative data

We study a multiplicative randomized response method for obtaining responses to sensitive questions when the answers are quantitative. The method involves the respondent multiplying his sensitive answer by a random number from a known distribution, and giving the product to the interviewer, who does not know the value of the random number and thus receives a scrambled response. Some particular distributions for the random scrambling number are proposed and studied, and ways of generating the scrambling numbers are discussed. Some modifications for increasing the efficiency of the method are proposed, and numerical results are given that show the scrambled response method is generally superior to the previously used method of randomizing questions.     

Effects of facial expression and stare duration on walking speed: Two field experiments

Two field experiments investigated the generality of the stare-escape phenomenon for pedestrians. Experiment 1, conducted at a traffic intersection, failed to replicate a previous finding that being stared at leads to faster walking speed. One hypothesis that could explain this failure is that the relatively short staring times used in Experiment 1 were insufficient for subjects to attribute a threatening meaning to the stare. In Experiment 2, conducted at a library elevator, duration of staring was systematically varied—either 2 seconds or more than 15 seconds. Consistent with the attribution time hypothesis, subjects increased walking speed after a long stare but decreased it after a short stare. In both experiments a smile coupled with a stare appeared to neutralize the effects of a stare alone.The authors would like to thank Clyde Hendrick for his valuable comments on an earlier draft of this paper.     

The Single-Parent Family in Australia: An Overview

Studies of single-parent families in Australia are reviewed and statistical trends related to this type of family pattern are discussed. It is quite evident that family sociology has paid little attention to this growing population in Australia. The categories reviewed include single parents, unmarried mothers, widows, deserted wives and the families of prisoners.
