Relighting the Campfire: Rediscovering Activity-Based Group Work

Group Work Camp, sponsored by Association for the Advancement of Social Work with Groups (AASWG) and held during the summers of 2009 and 2011 on the campus of George Williams College of Aurora University, provided unique opportunities for educators, practitioners, and students to experience the power of collective action and activity/experience-based groups. The camp reminded participants of the origins of the group work movement and how the prevalence of experientially based group practice has diminished over the past few decades. Further, this camp experience served as an awakening and may have particular import for U.S.-based practitioners to align with emerging trends in global social group work.     

Multiple votes,ballot truncation and the two-party system: an experiment

Duverger’s law states that Plurality Voting tends to favor a two-party system. We conducted laboratory experiments to study whether voting procedures other than Plurality Voting could favor a two-party system as well. Plurality Voting is compared with Approval Voting and Dual Voting, both of which allow to vote for multiple candidates, but differ in whether voters are required to cast all their votes. We find that in most elections held under Plurality Voting and Approval Voting, at most two candidates are viable. By contrast, three candidates are viable in a sizable number of elections held under Dual Voting due to strategic voting. Our evidence suggests that Approval Voting may encourage a two-party system, whereas Dual Voting may encourage multipartism. The voters’ ability to truncate ballots (i.e., not cast all their votes) is essential for supporting the two-party system under Approval Voting.     

Are substance use prevention programs more effective in schools making adequate yearly progress? A study of Project ALERT

This exploratory study sought to determine if a popular school-based drug prevention program might be effective in schools that are making adequate yearly progress (AYP). Thirty-four schools with grades 6 through 8 in 11 states were randomly assigned either to receive Project ALERT (n = 17) or to a control group (n = 17); of these, 10 intervention and nine control schools failed to make AYP. Students completed three self-report surveys. For lifetime cigarette use and 30-day alcohol use, Project ALERT was more effective in schools that made AYP. However, in these schools, Project ALERT negatively affected students' lifetime marijuana use. This study provided some preliminary evidence that prevention programming may not work as well in poorer performing schools; however, further exploration is needed.     

Urban areas may serve as habitat and corridors for dry-adapted,heat tolerant species; an example from ants

We collected ants from six urban and one forest land-use types in Raleigh, NC to examine the effects of urbanization on species richness and assemblage composition. Since urban areas are warmer (i.e., heat island effect) we also tested if cities were inhabited by species from warmer/drier environments. Species richness was lower in industrial areas relative to other urban and natural environments. There are two distinct ant assemblages; 1) areas with thick canopy cover, and 2) more disturbed open urban areas. Native ant assemblages in open environments have more southwestern (i.e., warmer/drier) distributions than forest assemblages. High native species richness suggests that urban environments may allow species to persist that are disappearing from natural habitat fragments. The subset of species adapted to warmer/drier environments indicates that urban areas may facilitate the movement of some species. This suggests that urban adapted ants may be particularly successful at tracking future climate change.     

Perceived continuing education needs and job relevance of health education competencies among health education and promotion practitioners in college health settings

Objective and Participants: The author conducted this study to determine college health education and promotion practitioners' perceived continuing education needs and perceived job relevance in relation to national health education responsibilities and competencies. Methods: In Spring 2006, the author invited college health education and promotion professionals to participate in an online survey, using 3 listservs. Of 276 individuals visiting the Web site, 141 participants completed the survey (51%). Participants rated their perceived training needs and job relevance for the 35 National Commission for Health Education Credentialing (NCHEC) competencies as well as preferred training formats. Results: Participants identified the following competencies as those in which they needed additional training: designing data-collection instruments, securing fiscal resources, interpreting evaluation and research results, carrying out evaluation and research plans, and developing plans for evaluation and research. They identified the following competencies as being the most relevant to their jobs: demonstrating a variety of skills in delivering strategies, interventions, and programs; using a variety of methods to implement strategies, interventions, and programs; initiating a plan of action; and using health-related information resources. The most preferred methods of obtaining additional continuing education were attending the American College Health Association annual meeting (67%) and completing home self-study print materials (67%). Conclusions: Collegiate professional organizations should offer a variety of continuing education opportunities centering on NCHEC competencies, specifically those perceived as needed by study participants.     

Dynamic Pricing and Inventory Management with Regular and Expedited Supplies

We consider a periodic‐review inventory system with regular and expedited supply modes. The expedited supply is faster than the regular supply but incurs a higher cost. Demand for the product in each period is random and sensitive to its selling price. The firm determines its order quantity from each supply in each period as well as its selling price to maximize the expected total discounted profit over a finite or an infinite planning horizon. We show that, in each period if it is optimal to order from both supplies, the optimal inventory policy is determined by two state‐independent thresholds, one for each supply mode, and a list price is set for the product; if only the regular supply is used, the optimal policy is a state‐dependent base‐stock policy, that is, the optimal base‐stock level depends on the starting inventory level, and the optimal selling price is a markdown price that decreases with the starting inventory level. We further study the operational impact of such supply diversification and show that it increases the firm's expected profit, reduces the optimal safety‐stock levels, and lowers the optimal selling price. Thus that diversification is beneficial to both the firm and its customers. Building upon these results, we conduct a numerical study to assess and compare the respective benefit of dynamic pricing and supply diversification.     

Beliefs of Guilt and Recommended Sentence as a Function of Juror Bias in the O. J. Simpson Trial

During the week of April 9, 1995, 125 male participants completed a questionnaire assessing attitudes toward the O. J. Simpson trial. Specifically, participants reported their belief in the defendant's guilt or innocence, stated how fair they perceived the trial to be, and recommended a sentence should the defendant be found guilty of the crime. Additionally, participants completed Kassin and Wrightsman's Juror Bias Scale and the revised California F scale. Overall, results showed that participants' scores on both scales were positively correlated with their beliefs in the defendant's guilt, perceived trial fairness, and more severe sentence recommendations.
