Technical Controversy and Ballistic Missile Defence: Disputing Epistemic Authority in the Development of Hit-to-Kill Technology

Public debate about Ballistic Missile Defence (BMD) has long centred on the question of feasibility, particularly as regards the realism of testing. Thus BMD opponents have argued that flight-tests are insufficiently similar to operational use to provide a reliable guide to real-world performance. However, an in-depth account of the development of US hit-to-kill technology—an approach to BMD that relies on the direct impact of an interceptor on the enemy missile warhead—reveals a far less-recognised issue: some BMD supporters have specific technical doubts which centre on the design of the current system rather than on its testing. These concerns hinge on contrasting claims to epistemic authority between two camps of BMD supporters. On the one hand, advocates of space-based BMD oppose the current system on in-principle conceptual grounds. On the other hand, some BMD supporters close to the development of ground-based hit-to-kill technology claim that the empirical evidence from testing shows that the current design is suboptimal because it is the outcome of a bureaucratic politics compromise between the two camps. Although the battle for epistemic authority has swung in favour of the latter hit-to-kill supporters recently, the lack of operational experience with a defence against nuclear-armed ballistic missiles means that further disputes are likely. So long as empirical knowledge claims rest solely on testing, they are unlikely to prove sufficiently politically compelling to silence advocates of space-based defence.     

Mother's choice: An exploration of extended self in infant clothing consumption

Consumption behaviour has long been linked to identity and notions of the self, where materialistic behaviours and attitudes are seen as determinants of self‐image. Previous literature has focused on mothers' consumption in general, but not specifically in regard to identity construction through purchasing for an infant. There is a dearth of academic research understanding mothers' consumption behaviour that links identity construction with infant clothing, where the child is part of the mothers' extended self and display of self‐identity. This qualitative, exploratory study provides insight into how mothers construct and express their identity through the extended self, contributing to consumer culture theory. The study examines the purchasing motivations of 14 mothers, utilizing depth interviews and projective association techniques. The findings indicate three predominant drivers underlying mothers' consumption, namely prioritizing the child, self‐representation and conspicuous branding.

‘Play skills’ for shy children: development of a Social Skills Facilitated Play early intervention program for extremely inhibited preschoolers

The aim of the present study was to develop and provide a preliminary evaluation of a social‐skills‐based early intervention program specifically designed to assist extremely inhibited preschoolers. Participants were a sample of n=22 extremely inhibited preschool‐aged children, who were randomly assigned to either the Social Skills Facilitated Play (SST) or Waitlist Control (WLC) condition. As compared to wait‐list controls, extremely inhibited children who participated in the SST‐facilitated play program sessions demonstrated a significantly greater post‐intervention decrease in observed socially wary behaviours and a significantly greater increase in social and socially competent behaviours at preschool. Results are discussed in terms of the importance of developing and refining early intervention programs for extremely inhibited young children. Copyright © 2010 John Wiley & Sons, Ltd.     

The Effect of Training on Preparatory Attention in Older Adults: Evidence for the Role of Uncertainty in Age-Related Preparatory Deficits

Thirty-two older adults and 20 younger adults completed a simple visual detection task in which the preparatory interval (PI; 1, 3, and 5 s) that separates the warning signal from the target varied randomly on each trial. Participants were divided into two groups. In a control condition, participants completed four blocks of trials with the three PIs occurring equally often within a block. In the experimental condition, participants completed an equal probability block (Block 1) followed by two blocks (Blocks 2 and 3) in which the shortest PI (1 s) occurred on 2/3 of the trials, followed again by an equal probability block (Block 4). In Block 1, the results indicated a larger PI effect in older than younger participants, independent of general slowing. Increasing the likelihood of the shortest PI (Blocks 2 and 3 in the experimental condition) improved RT in older and younger adults and led to an equivalent PI effect in both age groups. This was not observed in the control condition, in which the age-related difference persisted during the four blocks of trials. Importantly, the improvement observed in the experimental group was maintained in the fourth block, where the PIs were reverted to an equal probability distribution. This supports the hypothesis that elderly participants prepare for events that have the greatest probability of occurrence and that this is a flexible process that can be modulated with brief training.     

Merging Professional Training and Community Engagement Agendas: A Case Study

This case study explored the emancipatory foundations of community work through a schools-based peer support intervention. We use a case study approach to describe the context in which the intervention was developed, its emancipatory theoretical foundations, and the project's implementation components and process. The findings suggest that reflexivity is a useful tool for community engagement and for articulating tensions that arise in the enactment of community participation, empowerment and conscientisation. The intervention presented a unique opportunity to reflect on the operationalisation of theoretical concepts in community psychology, and to train professional psychologists for reflexive community work.     

Responsible Alcoholic Beverages Sales and Services Training Intervention in Cape Town: A Pilot Study

The aim of this study was to pilot a responsible beverage service intervention in order to reduce alcohol-impaired road use. The sample included 20 shebeens including 10 licensed and 10 unlicensed establishments chosen from a list of alcohol serving establishments in Gugulethu, Cape Town. The study examined whether changes in knowledge, attitudes, and behaviour of servers as well as BAC levels of patrons occurred as a result of receiving server intervention training. Results indicate that the training programme was effective in changing serving practices consistent with the techniques and strategies emphasized in the training. However, the breathalyser results for baseline and follow-up, respectively, in the intervention and control group did not show differences among patrons. It is recommended that mandatory server training be introduced in South Africa for licensed establishments and develop an incentive system to encourage voluntary use of server training for unlicensed establishments.     

Perfecting not Perfect: Christology and Pneumatology within an Imperfect Yet Purposeful Creation

Abstract

The issue of evolutionary theodicy remains an area of difficulty within the science–theology dialogue. The evolutionary understanding of life identifies a process where suffering and extinction are intrinsic; however, theology seeks to articulate God's loving goodness towards creation. Therefore the central question of evolutionary theodicy becomes: “How can a loving God act by such a process?” Within the view of theistic evolution, evolutionary theodicy has resulted in a deeper understanding of Christology and Pneumatology, as the whole of creation is understood to be moving towards its eschatological perfection in Christ.     

The Effect of Retention Interval Task Difficulty on Young Children's Prospective Memory: Testing the Intention Monitoring Hypothesis

The current study examined the impact of retention interval task difficulty on 4- and 5-year-olds’ prospective memory (PM) to test the hypothesis that children periodically monitor their intentions during the retention interval and that disrupting this monitoring may result in poorer PM performance. In addition, relations among PM, working memory, theory of mind (ToM), and 2 types of planning were investigated. Children (N = 64) were randomly assigned to an easy or difficult filler task during the retention interval prior to the PM task. Five-year-olds outperformed 4-year-olds on the PM task, and children receiving the easy filler task outperformed those receiving the difficult filler task. Further, working memory, planning, and ToM were positively associated with PM for children receiving the difficult filler task but not for children receiving the easy filler task. Findings are interpreted with respect to the predictions of the intention monitoring hypothesis as well as the multiprocess framework of PM.     

Distributive Justice Beliefs are Guided by Whether People Think the Ultimate Goal of Society is Well-Being or Power

Abstract

Disagreements about how resources should be distributed are often heated, perhaps because people suspect that distributive justice beliefs that clash with their own derive from nefarious motives. In this paper, we consider a less pessimistic explanation for diversity in distributive justice beliefs: such beliefs are influenced by what one considers the primary utility or value of their society in the first place. In five studies (N?=?21,515), we demonstrate the existence of two separable types of distributive justice beliefs, one (Equality/need) influenced by a focus on societal well-being, and the other (Equity/merit) by a focus on societal power. These findings lend insight into how growing tensions rooted in resource allocation might be defuzed.
