Effectiveness of Visual Prompts on Correct Disposal of Trash and Recyclable Materials

Recycling is an important and socially significant behavior for which behavior analytic interventions could be greatly beneficial. In the present study, the effectiveness of various visual prompts on increasing correct disposal of trash and recycling items was evaluated with four graduate students. Three visual prompts of varying complexity were compared in an alternating treatments design. The results indicated that visual prompts are an effective way to increase correct disposal of recycling and trash items. However, the results did not show differentiation between the visual prompts for three of the four participants

Reliability and Validity of the Teen Substance Abuse Rating Scale.

This study used 57 adolescent substance abusers receiving treatment and 510 adolescent controls in a validation of the Teen Substance Abuse Rating Scale (TSARS; Hemstreet, 1991). The TSARS was originally designed as a relatively brief, easy to read self-report questionnaire to discriminate between adolescent substance abusers and nonabusers. The 92 items of the TSARS represent specific behaviors that are answered in a Yes/No format. The TSARS was examined to determine if it would meet validity criteria presented by Winters (1990) and Swadi (1990), as well as those presented in the Standards for Educational and Psychological Testing (APA, 1985). A principal components factor analysis revealed 2 stable TSARS factors including a total of 53 of the original TSARS items. Further analyses were completed on the revised 53-item TSARS. Factor 1, Substance Usage, appeared to relate primarily to adolescent substance involvement, while Factor 2, Interpersonal Skills, was broadly construed as representative of specific social skills. Internal consistency was found to be adequate for the 53 TSARS items (Alpha = 0.94). Significant correlations (p $\u3c$.01) were found between the TSARS and two measures of adolescent substance abuse, the Personal Experience Inventory (PEI; Winters & Henley, 1989) and the Substance Abuse Subtle Screening Inventory (SASSI; Miller, 1985). A discriminant function analysis showed the TSARS discriminated significantly (p $\u3c$.0000) between adolescent substance abusers and controls. The TSARS classified 92.65% of the subjects by group correctly. A Lie Scale included as part of the TSARS was also examined. It was reduced from 12 to 9 items that met an endorsement rate of $\u3e$.90 or $\u3c$.10. The 9-item Lie Scale showed promise as a possible measure of atypical response patterns, but further evidence is needed of its reliability. Though several limitations of this study were presented, the TSARS showed promise of becoming a widely used and researched self-report measure of adolescent substance abuse

“Th’ estate which wits inherit after death” : immortality in Pope’s Temple of Fame and the “Battle of the Books”

In this report, I examine Alexander Pope’s Temple of Fame in terms of its rhetorical structure as well as its “place” in the post-classical canon. I offer three critical assessments: 1) that Pope’s poem frames itself as a response to Swift’s “Battle of the Books” within the historical moment of a Humanist split; 2) that both Swift’s text and Pope’s represent literary immortality as a central problem in the Ancient-Modern controversy; and 3) that Pope’s poem consciously locates itself within a classical and Humanist tradition of literary self-eternization. I suggest that for Pope, the significance of the Ancients was not merely their primacy or objective excellence, but also their status as a foundation on which the very possibility of literary immortality was predicated. Pope’s Temple, understood in the context of the “battle,” thus invites a reevaluation of the role of classical eternizing rhetoric both in shaping Pope’s own career and, more broadly, in defining the principles of Humanism.Englis

Opportunity Threads and Worker-Ownership: Lessons from Practice: A Word from the Plant Floor

About Opportunity Threads: Opportunity Threads is a worker-owned cut-and-sew plant based in Morganton, North Carolina. Each day we create and ship apparel and soft goods — blankets, pillows, and bags — to companies across the US and abroad. We are proud to continue the state’s tradition of high-quality textile production. Introduction: North Carolina, a longtime leader in the textiles industry, has been threatened by offshoring, unfavorable trade policies, and the drive for cheap consumer goods. North Carolina lost a staggering 120,000 textile jobs between 1995 and 2010. Despite the return of some textile jobs, the challenge remains: how to maintain a heritage industry, with stable and fair conditions, that helps our communities flourish. In order for manufacturing jobs to come back to North Carolina in a fair and equitable manner, the ownership and managerial structures of the textile manufacturing industry must shift

On the nature of ferromagnetism in diluted magnetic semiconductors: GaAs:Mn, GaP:Mn

A microscopic Hamiltonian for interacting manganese impurities in diluted magnetic semiconductors (DMS) is derived. It is shown that in p -type III-V DMS the indirect exchange between Mn impurities has similarities with the Zener mechanism in transition metal oxides. Here the mobile holes and localized states near the top of the valence band play the role of unoccupied oxygen orbitals which induce ferromagnetism. The Curie temperature estimated from the proposed kinematic exchange agrees with recent experiments on GaAs:Mn. The model is also applicable to the GaP:Mn system.Comment: 10 pages, 3 figures.
