The effect of self-recording and social reinforcement components of parent training programs

This investigation attempted to assess the effectiveness of two components of parent training programs: (1) the effect of a self-behavior management project prior to intervention with deviant child behaviors, and (2) that of social reinforcement from peers and the consultant. Four groups of parents were exposed to a basic training program and were measured on their success in an intervention program in the inappropriate behavior of their children (ages 7–9 years). Two groups of parents were requested to do a self-modification program prior to the intervention with deviant child behavior; two groups did a child intervention program without a self-management project. One group in the self-management and one group without self-management received verbal social reinforcement from peers and the consultant during interventions. Results obtained indicate that the parent group whose training involved a self-behavior management project prior to intervention with their child's inappropriate behavior and verbal social reinforcement achieved a significantly greater reduction of these behaviors when compared to the groups where either self-management of social reinforcement was used.     

Behavioral contrast produced by a signaled decrease in local rate of reinforcement

Pigeons' key pecking in the presence of one stimulus (S1) was reinforced according to a response-dependent variable-interval schedule. Pecking rate during S1 increased (behavioral contrast) when a second stimulus (S2) [associated with either a response-dependent fixed-interval schedule (Experiment I) or a response-independent reinforcement schedule in which reinforcement availability was signaled by visual (Experiment II) or temporal (Experiment III) stimuli] alternated with S1. These experiments suggest that a discriminable, signaled decrease in local reinforcement rate during S2 is an antecedent of the behavioral contrast response rate increases during S1.     

Group caution at the race track

McCauley, Stitt, Woods and Lipton's finding that groups were more conservative than individuals when betting at a race track has been criticized on statistical and methodological grounds. The present study which does not suffer the shortcomings for which McCauley et al. were legitimately criticized does, nonetheless, sustain their general results and conclusions. Groups were significantly more cautious than individuals when wagering $2.00 on a horse race.     

Real and virtual classrooms can trigger the same levels of stuttering severity ratings and anxiety in school-age children and adolescents who stutter

PurposeMany school-age children and adolescents who stutter experience the fear of public speaking. Treatment implications include the need to address this problem. However, it is not always possible to train repeatedly in front of a real audience. The present study aimed to assess the relevance of using a virtual classroom in clinical practice with school-age children and adolescents who stutter.MethodsTen children and adolescents who stutter (aged 9–17 years old) had to speak in three different situations: in front of a real audience, in front of a virtual class and in an empty virtual apartment using a head-mounted display. We aimed to assess whether the self-rated levels of anxiety while speaking in front of a virtual audience reflect the levels of anxiety reported while speaking in front of a live audience, and if the stuttering level while speaking to a virtual class reflects the stuttering level while speaking in real conditions.ResultsResults show that the real audience creates higher anticipatory anxiety than the virtual class. However, both the self-reported anxiety levels and the stuttering severity ratings when talking in front of a virtual class did not differ from those observed when talking to a real audience, and were significantly higher than when talking in an empty virtual apartment.ConclusionOur results support the feasibility and relevance of using a virtual classroom to expose school-age children and adolescents who stutter to a feared situation during cognitive behavioral therapy targeting the fear of public speaking.     

Factors influencing public awareness of autonomous vehicles: Empirical evidence from Brisbane

Growing concerns, regarding transport disadvantage and increased socioeconomic disparities, demand innovative ways to improve equity and make transportation systems smarter. One of the most anticipated developments within the field of smart mobility is driving automation systems. Autonomous vehicles (AVs) have the potential to improve accessibility, affordability, safety and efficiency of transport systems, but come with risks including the intensification of private vehicle travel. Understanding public awareness is an important step to determine whether motivation and intention to use AVs will impact on its potential. This paper aims to investigate factors influencing public awareness of AVs as a solution to transport disadvantage. The study applies an ordinal logistic regression analysis to analyse survey data collected from the residents of Brisbane (Australia). Our findings reveal that awareness is positively correlated within young and middle-aged adults, low-income residents, disability, public transport users, and those who feel unsafe on public transport, while an increase in the number of household vehicles is negatively correlated. The study provides insights into public awareness towards the potential benefits of AVs, and highlights potential opportunities and challenges associated with these expectations.     

The Lambeth Appeal and the Appeal of Britain

In 1920, the Lambeth Conference of Anglican bishops issued the “Appeal to All Christian People.” While much has been written on its genesis in 1920 and its impact on the later ecumenical movement and on Anglicanism, much less has been written about the relationship of the sort of ecumenism espoused by the Lambeth Appeal to the international political developments of the time. This article assesses the impact of the First World War and the Versailles Settlement on some of the assumptions underlying the Lambeth Appeal, examining how the appeal was in many ways a by-product of a new form of internationalism, which itself was closely related to the reinterpretation of the British Empire that emerged during the war.     

A focus group study on the potential of autonomous vehicles as a viable transportation option: Perspectives from people with disabilities and public transit agencies

Autonomous vehicle (AV) technology is becoming one of the most promising alternatives to improve mobility for people with disabilities. Nevertheless, how people with disabilities perceive AV as transportation services has not been explored. Also, limited information exists about how public transit agencies comprehend and perceive autonomous vehicle transportation (AVT) services. This study discusses mobility issues for people with disabilities and explores the potential of AVT to serve that population, particularly those with visual impairments or physical disabilities. Researchers conducted six focus groups comprising people with disabilities (N = 23) and public transit service experts (N = 10) in Austin, Texas and Houston, Texas. Each session was audio-recorded and analyzed using conventional content analysis. This study identified people with disabilities’ mobility issues related to: (1) current transit services (including fixed-route and paratransit services) and (2) the quality of neighborhood built environments. Both people with disabilities and transit experts expected that AVT could mitigate current mobility issues, especially in improved built environments. However, participants with disabilities also expressed concerns and anxieties regarding AVT. Transit experts agreed that more targeted strategies would be needed to overcome possible barriers to AVT for people with disabilities. This study provides insights on shaping AVT strategies and policies relevant to improving mobility for people with disabilities.     

Why? Versus Why Not?: Potentialities of Aging in Shaw's Back to Methuselah

Bernard Shaw's critique of society's sacred cows, as well as his participation in the social, cultural and political marketplace in which he lived, resemble the new historical/cultural materialism of contemporary theory. In Back to Methuselah, Shaw examines the notions of aging and illuminates the degree to which our chronological standards of old age are sociological not biological constructs. This tour de force on aging both dramatizes age as a function of societal and/or individual choice, not as a biological given, and juxtaposes opinions toward aging in such a way that flexible attitudes toward the subject emerge.
