EFFECT OF REINFORCEMENT PROBABILITY AND PRIZE SIZE ON COCAINE AND HEROIN ABSTINENCE IN PRIZE‐BASED CONTINGENCY MANAGEMENT

Although treatment outcome in prize‐based contingency management has been shown to depend on reinforcement schedule, the optimal schedule is still unknown. Therefore, we conducted a retrospective analysis of data from a randomized clinical trial (Ghitza et al., 2007) to determine the effects of the probability of winning a prize (low vs. high) and the size of the prize won (small, large, or jumbo) on likelihood of abstinence until the next urine‐collection day for heroin and cocaine users (N = 116) in methadone maintenance. Higher probability of winning, but not the size of individual prizes, was associated with a greater percentage of cocaine‐negative, but not opiate‐negative, urines.     

Teachers' views and beliefs about bullying: Influences on classroom management strategies and students' coping with peer victimization

A multilevel design was used to test a model in which teachers' attitudes (beliefs) about bullying (e.g., it is normative; assertive children do not get bullied; children wouldn't be bullied if they avoided mean kids) were hypothesized to influence if and how they intervene in bullying interactions. In turn, it was hypothesized that teachers' strategies would influence how their students cope with victimization and the frequency of victimization reported by their students. Data were gathered on 34 2nd and 4th grade teachers and 363 ethnically-diverse students (188 boys; 175 girls; M age = 9 years 2 months). Results indicated that teachers were not likely to intervene if they viewed bullying as normative behavior, but were more likely to intervene if they held either assertion or avoidant beliefs. Moreover, avoidant beliefs were predictive of separating students which was then associated both directly and indirectly (via reduced revenge seeking) with lower levels of peer victimization. No grade differences emerged for teachers' views or management strategies; however, minor sex differences were detected which will be discussed.     

Deliberative Pedagogy: Ideas for Analysing the Quality of Deliberation in Conflict Management in Education

Institutions worldwide respond to the need to recognise the value of educating children and young people to handle or solve conflicts in communication. But how do they or we know that an event is correctly interpreted as a conflict? How can people analyse the quality of deliberation when handling or solving conflicts in communication in education? I discuss these questions and argue that the notion of conflict cannot be defined only in terms of incompatibility, clash, opposition and/or disagreement; it also has to encompass negativity in the approach to the other. I also argue that the quality of deliberation can be analysed through a deliberative pedagogical approach, which takes into account structural features of deliberation and required dispositions of the participants, and that our knowledge of conflicts emerges holistically and is interpersonal and objective. I begin by giving an account of some institutional responses to conflicts. Then I discuss the notion of conflict and define it, inter alia, in terms of incompatibility, disagreement and negativity. Finally, I discuss ideas for analysing the quality of deliberation in communication when handling or solving conflicts in education.

How Risk is Perceived, Constructed and Interpreted by Clients in Clinical Genetics, and the Effects on Decision Making: Systematic Review

As an individual’s understanding of their genetic risk may influence risk management decisions, it is important to understand the ways in which risk is constructed and interpreted. We systematically reviewed the literature, undertaking a narrative synthesis of 59 studies presenting data on the ways in which individuals perceive, construct and interpret their risk, and the subsequent effects. While most studies assessed perceived risk quantitatively, the combined evidence suggests individuals find risk difficult to accurately quantify, with a tendency to overestimate. Rather than being a stand-alone concept, risk is something lived and experienced and the process of constructing risk is complex and influenced by many factors. While evidence of the effects of perceived risk is limited and inconsistent, there is some evidence to suggest high risk estimations may adversely affect health and lead to inappropriate uptake of medical surveillance and preventative measures by some individuals. A more focused approach to research is needed with greater exploration of the ways in which risk is constructed, along with the development of stronger theoretical models, to facilitate effective and patient-centered counseling strategies.     

To Recycle or Not to Recycle? An Intergenerational Approach to Nuclear Fuel Cycles

This paper approaches the choice between the open and closed nuclear fuel cycles as a matter of intergenerational justice, by revealing the value conflicts in the production of nuclear energy. The closed fuel cycle improve sustainability in terms of the supply certainty of uranium and involves less long-term radiological risks and proliferation concerns. However, it compromises short-term public health and safety and security, due to the separation of plutonium. The trade-offs in nuclear energy are reducible to a chief trade-off between the present and the future. To what extent should we take care of our produced nuclear waste and to what extent should we accept additional risks to the present generation, in order to diminish the exposure of future generation to those risks? The advocates of the open fuel cycle should explain why they are willing to transfer all the risks for a very long period of time (200,000 years) to future generations. In addition, supporters of the closed fuel cycle should underpin their acceptance of additional risks to the present generation and make the actual reduction of risk to the future plausible.     

Adapting REBT to the World of Business

Although REBT was developed as a therapeutic approach in the field of clinical psychology, its very direct and pragmatic approach to enhancing human functioning makes it exceptionally effective when adapted to the sphere of consulting to businesses. However, to be successful, a REBT clinician needs to take into consideration the different culture, the different client, and the different types of problems one is faced with in the corporate world versus the clinical world. Clinical concepts and vocabulary had best be changed so as to appear more educational and business-like. Whether used in a one-on-one coaching situation, in a group setting with a team, or with a family business to resolve conflict, the overriding goal is enhanced functioning on the job and ultimately, increased growth and profits for the business.     

Social-identity functions of attraction to organizations

This article examines the self-presentation goals that underlie attraction to organizations. Expanding on Lievens and Highhouse’s (2003) instrumental vs. symbolic classification of corporate attributes, a theory of symbolic attraction is presented that posits social-identity consciousness as a moderator of the relation between symbolic inferences about organizations (e.g., this company is dynamic and innovative) and attraction to those organizations. A measure of social-identity consciousness is developed, and a series of studies confirmed two dimensions, labeled concern for social adjustment and concern for value expression. Preliminary evidence supports the validity of the measure and its role in moderating attraction to symbolic features of well-known firms.
