Modified TC for MICA offenders: crime outcomes

The study randomly assigned male inmates with co-occurring serious mental illness and chemical abuse (MICA) disorders to either modified therapeutic community (MTC) or mental health (MH) treatment programs. On their release from prison, MICA inmates who completed the prison MTC program could enter the MTC aftercare program. The results, obtained from an intent-to-treat analysis of all study entries, showed that inmates randomized into the MTC group had significantly lower rates of reincarceration compared with those in the MH group. The results also show that differences between the MTC + aftercare and comparison group across a variety of crime outcomes (i.e. any criminal activity, and alcohol or drug related criminal activity) are consistent and significant, and persist after an examination of various threats to validity (e.g. initial motivation, duration of treatment, exposure to risk). This study provides some support for the effectiveness of the prison TC only condition. The findings are encouraging and consonant with other studies of integrated prison and aftercare TC programs for substance abusing non-MICA offenders, although qualified by the possibility that selection bias (i.e. differences in motivation on entry into aftercare) may be operating. Nevertheless, given the available evidence and the need for effective programming for MICA offenders, program and policy makers should strongly consider developing integrated prison and aftercare modified TC programs for MICA offenders.     

Towards the feeling of emergence

Emergence is a multi-dimensional notion; the meanings it has acquired span the mythopoetic to the scientific, especially as found in complex systems. Examples of emergence in Navaho and Egyptian imagery underscore its diverse cultural origins and applications as well as suggesting an underlying archetypal quality to the core concept. A brief overview of the use of this term in science starting in the 17th century helps to locate the roots of modern emergent views in the philosophy of Leibniz. Jung's own use of early systems approaches was a part of his formulations of a 'third' position associated with the transcendent function. As this paper was delivered at the 50th anniversary conference of the Journal of Analytical Psychology, aspects of the emergence of the Journal within the contents of the first issue are explored. Attention is drawn to several articles, especially a case of brief child therapy done by Robert Moody. His approach to working his case is strikingly modern and vividly demonstrates principles of emergence within the clinical setting. Following this there is a discussion of some neuroscientific research on neural body maps, pointing to the experience of feelings as an emergent process. It is suggested that feelings derive from phase transitions in the brain's body mapping states. A reconsideration of a seeming impasse in the case described by Moody leads instead to a view of the initial phase of treatment as a pre-critical period. Research findings on mirror neurons are presented in terms of the feeling of empathy. Subjective feelings are then shown to be associated with moments of emergence, especially surprise and curiosity, exemplified by a case from the author's practice.     

Image analysis of small animal feeding behavior

The optimal design of behavioral experiments includes measures to minimize observer bias while maximizing researcher efficiency. To this end, we have developed a reliable, autonomous monitor of animal feeding behavior. Previous studies of caterpillar (Manduca sexta) feeding have relied on human observation for visual evaluation of food consumption at specific time points over the course of several hours. This method is eliminated by our newbehavior rig, which collects data automatically. Individual animals are monitored via CCD cameras activated in sequence by a computer. Images are obtained at preset time intervals using a frame grabber to capture still pictures from the cameras. Subsequently, images are analyzed using software written in MatLab to determine food selection and quantify consumption.     

Multivariate Extreme Value Distributions and Coverage of Ranking Probabilities

The main result in this paper is that the class of multivariate extreme value distributions, when used as random utility models, can approximate all ranking probability distributions. This extends Theorem 1 of Dagsvik (1995). Copyright 2001 Academic Press.     

Differential Reinforcement of Alternative Behavior in Center-Based Classrooms: Evaluation of Pre-teaching the Alternative Behavior

This study investigated the effectiveness of a differential reinforcement of alternative behavior procedure in decreasing disruptive behavior while simultaneously increasing the appropriate behavior of four children of typical development between the ages of 4 and 6 in center-based classrooms. We began with brief functional analyses for each child. Then, differential reinforcement procedures, with and without pre-teaching the alternative behavior, were compared using an alternating treatments design. Results indicated that the differential reinforcement procedure with pre-teaching resulted in lower levels of problem behavior and greater levels of the alternative behavior compared to differential reinforcement alone. Results are discussed in terms of implications for applied practice and functional assessment and intervention research.     

Talking to Visitors about Conservation: Exploring Message Communication through Docent–Visitor Interactions at Zoos

ABSTRACT

Education personnel, both paid staff and volunteers, are often used at zoos and other museums as a channel to disseminate educational messages. This exploratory study examined the use of zoo docents to communicate key conservation messages from the zoo to visitors. The study was conducted in 2 phases using an emergent design with mixed methods. The findings suggest that visitors perceive docents to be an important source for conservation messages even though observed message communication through docent–visitor interactions was very limited. Docents view themselves as “facilitators for learning”, but their limited awareness of the institution's messages inhibits their ability to communicate these messages to visitors. Other factors that influence incidence of message communication are duration of the interaction, nature of the exhibit/region, and group composition. In this study, signage was found to be an effective channel for building cognitive awareness of messages among visitors.     

Business owner-managers' descriptions of entrepreneurship: A content analysis

Abstract

Entrepreneurship is one of the most researched topics in business research. Findings have been mixed regarding the traits of entrepreneurs, and interest has grown in examining the behavioral aspects and business operations elements necessary for effective entrepreneurship, branching out from the focus on personality traits that has dominated the literature. We explored the area of entrepreneurship with the goal of developing a useful framework for viewing this domain. Content analysis was used to build the framework from business owner-managers' observations of entrepreneurial effectiveness. The construct categories and the overall dimensions and their relationships to entrepreneurship are reported. The result is the beginning of a process to describe an entrepreneurship system. Suggestions for future research and the continuation of entrepreneurship model development are offered.     

The cognitive and neural basis of option generation and subsequent choice

Decision-making research has thoroughly investigated how people choose from a set of externally provided options. However, in ill-structured real-world environments, possible options for action are not defined by the situation but have to be generated by the agent. Here, we apply behavioral analysis (Study 1) and functional magnetic resonance imaging (Study 2) to investigate option generation and subsequent choice. For this purpose, we employ a new experimental task that requires participants to generate options for simple real-world scenarios and to subsequently decide among the generated options. Correlational analysis with a cognitive test battery suggests that retrieval of options from long-term memory is a relevant process during option generation. The results of the fMRI study demonstrate that option generation in simple real-world scenarios recruits the anterior prefrontal cortex. Furthermore, we show that choice behavior and its neural correlates differ between self-generated and externally provided options. Specifically, choice between self-generated options is associated with stronger recruitment of the dorsal anterior cingulate cortex. This impact of option generation on subsequent choice underlines the need for an expanded model of decision making to accommodate choice between self-generated options.
