Enhancing Instruction via Instructive Feedback for a Child With Autism Using a Speech-Generating Device

The Analysis of Verbal Behavior - Instructive feedback (IF) is a procedure in which secondary targets are presented to a learner during instruction for primary skills. Previous research has...     

Risk of Fetal Mortality After Exposure to Listeria monocytogenes Based on Dose-Response Data from Pregnant Guinea Pigs and Primates

One‐third of the annual cases of listeriosis in the United States occur during pregnancy and can lead to miscarriage or stillbirth, premature delivery, or infection of the newborn. Previous risk assessments completed by the Food and Drug Administration/the Food Safety Inspection Service of the U.S. Department of Agriculture/the Centers for Disease Control and Prevention (FDA/USDA/CDC)^{( 1 )} and Food and Agricultural Organization/the World Health Organization (FAO/WHO)^{( 2 )} were based on dose‐response data from mice. Recent animal studies using nonhuman primates^{( 3 , 4 )} and guinea pigs^{( 5 )} have both estimated LD₅₀s of approximately 10⁷ Listeria monocytogenes colony forming units (cfu). The FAO/WHO^{( 2 )} estimated a human LD₅₀ of 1.9 × 10⁶ cfu based on data from a pregnant woman consuming contaminated soft cheese. We reevaluated risk based on dose‐response curves from pregnant rhesus monkeys and guinea pigs. Using standard risk assessment methodology including hazard identification, exposure assessment, hazard characterization, and risk characterization, risk was calculated based on the new dose‐response information. To compare models, we looked at mortality rate per serving at predicted doses ranging from 10^?4 to 10¹² L. monocytogenes cfu. Based on a serving of 10⁶ L. monocytogenes cfu, the primate model predicts a death rate of 5.9 × 10^?1 compared to the FDA/USDA/CDC (fig. IV‐12)^{( 1 )} predicted rate of 1.3 × 10^?7. Based on the guinea pig and primate models, the mortality rate calculated by the FDA/USDA/CDC^{( 1 )} is underestimated for this susceptible population.     

Visions of Protest. A Media‐Historic Perspective on Images in Social Movements

Social movements and the messages they wish to spread are essentially visual phenomena. Although this is both an obvious and momentous assertion, social movement research has been hesitant to integrate visual data. Until lately, most insights into the use of images in social movements originated from historical and media studies. This contribution presents the recent surge in literature devoted to the visual analysis of social movements. It focuses on activists' practices of image production and distribution under certain media‐historic constellations. In this perspective, the current opportunities to create and spread images of dissent are contrasted with previous appropriations of technical possibilities from early print to electronic media. In times of mobile devices combined with social network sites, scholars of movement images are confronted with profound changes in the ways images contribute to the emergence and dynamics of social movements. Thus, we argue for a media‐sensitive analysis of images in social movements.     

Mands for Information Using “How” Under EO-Absent and EO-Present Conditions

The present study replicates and extends previous research on teaching “How?” mands for information to children with autism. The experimental preparation involved mand training in the context of completing preferred activities and included training and testing under conditions when the establishing operation (EO) was present and absent. Results show that two children with autism acquired mands for information using How? only in situations where information was valuable (i.e., the EO was present); they then consistently made use of the information provided in activity completion. Generalization to novel, untaught situations was assessed.     

Receptivity to Change in a General Medical Practice

In this paper, Pettigrew, Ferlie and McKee's concepts of receptive and non receptive contexts for change are examined using data from an evaluation study of a general medical practice implementing a Personal Medical Services Pilot between 1998 and 2001. Four questions concerning the applicability, associatedness, temporality and dynamism of the eight factors Pettigrew et al. identified as constitutive of receptivity are used in the analysis, which extends the original model through an operationalization yielding 21 ‘focal questions’. Although the process of change at the fieldwork site was stalled, the receptivity model is shown to have been a useful tool in identifying the factors blocking change. The analysis shows that when the eight factors are conceptualized in terms of the strength, direction and continuity of their influence, the receptivity metaphor provides a distinctive tool for the analysis of change. The paper concludes that further refinement of the model could provide a basis for the derivation of change management typologies.     

The secret life of the city rat: a review of the ecology of urban Norway and black rats (Rattus norvegicus and Rattus rattus)

Norway rats (Rattus norvegicus) and black rats (Rattus rattus) are among the most prolific and widespread urban pest species in the world. Yet despite their ubiquity, a unified understanding of the ecology of these species in urban habitats eludes us. A comprehensive understanding of urban rat ecology is important for managing rat populations and mitigating the harmful effects that they may have on urban ecosystems (e.g., structural damage, food contamination, and disease spread). The objective of this systematic review and narrative synthesis is to collate, compare, and contrast data from the published literature regarding the ecology of Norway and black rats in urban centers. Themes emerging from the synthesis process, and discussed in detail, include population dynamics, behavior, movement, and environmental influences on rat populations.     

Incorporating Mindfulness and Chat Groups Into an Online Cognitive Behavioral Therapy for Mixed Female Sexual Problems

The current randomized study evaluated an online cognitive behavioral therapy program for female sexual problems. PursuingPleasure (PP) consisted of six online modules that included psychoeducation, sensate focus, communication exercises, cognitive exercises, and e-mail contact with a therapist. PP incorporated mindfulness training and online chat groups as well as assessed partner sexual functioning. Participants demonstrated a completion rate of 57%, with 26 women with female sexual problems and related distress completing the program compared to a wait-list control group of 31 women also experiencing sexual problems and distress. Sexual problems reported by women in both groups included difficulties with sexual desire, arousal, orgasm, and pain. The treatment group demonstrated significant improvements in all domains of female sexual response (except for sexual pain) and significant reductions in the reported frequency of sexual problems and distress. Partner sexual functioning showed positive change. Improvements in female sexual functioning and some improvements in male partner sexual functioning were maintained at three-month follow-up. Limitations and suitability of clients for this treatment approach for women who are geographically isolated, who are unable to attend face-to-face therapy, and who possess a high degree of motivation are discussed.     

Psychotropic medication management for youth in state care: consent, oversight, and policy considerations

The use of psychotropic medications in youth with emotional disturbances in state custody is increasing and presents unique challenges concerning consent and oversight. We examine various means that state child welfare agencies use to provide consent for and oversight of psychotropic medications for children in state custody and describe benefits of a consent process that provides for expert consultation to the child welfare agency and prescribing clinicians, case-specific and systemic oversight of psychotropic medication use, and education for stakeholders.
