Critical thinking (CT) skills are essential to academic and professional success. Instruments to assess CT often rely on multiple-choice formats with inherent problems. This research presents two instruments for assessing CT, an essay and open-ended group-discussion format, which were implemented in an undergraduate business course at a large public university. The topics were intentionally chosen to be digitally-related (internet access and social media) since they raise complex issues, are applicable in many disciplines, and students are avid users, thereby making these instruments relevant, multidisciplinary, engaging, and multifaceted. These instruments may be adapted to enable educators to effectively assess undergraduate students' ability to think critically. Qualitative analysis of the verbatim data with NVivo helps demonstrate the instruments' efficacy in assessing CT, with (1) high-quality responses receiving high grades, and (2) overarching themes identified by content analysis, that coalesce into the three dimensions of social justice theory (distributive, procedural, and interactional), thus illustrating students' consideration of complex fairness norms and societal needs. Excerpts of student responses are provided as illustrations of the indicators/evidence of critical thinking. Educators can use these instruments to first assess students' CT skills, and then devise targeted interventions to improve the quality of students' thought processes.

Conjugated block copolymers provide a pathway to achieve thermally stable nanostructured thin films for organic solar cells. We characterized the structural evolution of poly(3-hexylthiophene)-block-poly(diketopyrrolopyrrole-terthiophene) (P3HT-b-DPPT-T) from solution to nanostructured thin films. Aggregation of the DPPT-T block of P3HT-b-DPPT-T was found in solution by small-angle X-ray scattering with the P3HT block remaining well-solvated. The nanostructure in thin films was determined using a combination of wide and small-angle X-ray scattering techniques as a function of processing conditions. The structure in solution controlled the initial nanostructure in spin-cast thin films, allowing subsequent thermal annealing processes to further improve the ordering. In contrast to the results for thin films, nanostructural ordering was not observed in the bulk samples by small-angle X-ray scattering. These results suggest the importance of controlling solvent induced aggregation in forming nanostructured thin films of conjugated block copolymers.

The authors examined the publications and impact of highly productive business and management education (BME) scholars across the business disciplines of accounting, economics, finance, information systems, management, marketing, and operations management. Results from a hierarchical cluster analysis revealed five clusters of scholars: leading BME Scholars, leading discipline-focused BME scholars, high-profile BME scholars, focused BME scholars, and recognized BME scholars. The article includes a discussion of findings and their implications for BME scholarship, future BME scholars, and business schools.

The development of organic semiconductors for use in thermoelectrics requires the optimization of both their thermopower and electrical conductivity. Here two fundamentally different doping mechanisms are used to investigate the thermoelectric properties of known high hole mobility polymers: poly 3-hexylthiophene (P3HT), poly(2,5 -bis(3-tetradecylthiophen-2-yl)thieno[3,2-b]thiophene) (PBTTT-C14), and poly(2,5-bis(thiphen-2-yl)-(3,7-diheptadecantyltetrathienoacene)) (P2TDC17-FT4). The small molecule tetrafluorotetracyanoquinodimethane (F4TCNQ) is known to effectively dope these polymers, and the thermoelectric properties are studied as a function of the ratio of dopant to polymer repeat unit. Higher electrical conductivity and values of the thermoelectric power factor are achieved by doping with vapor-deposited fluoroalkyl trichlorosilanes. The combination of these data reveals a striking relationship between thermopower and conductivity in thiophene-based polymers over a large range of electrical conductivity that is independent of the means of electrical doping. This relationship is not predicted by commonly used transport models for semiconducting polymers and is demonstrated to hold for other semiconducting polymers as well. [ABSTRACT FROM AUTHOR]

Identifying how small molecular acceptorspack with polymer donorsin thin and thick (bulk) films is critical to understanding the natureof electrical doping by charge transfer. In this study, the packingstructure of the molecular acceptor tetrafluorotetracyanoquinodimethane(F4TCNQ) with the semiconducting polymer poly(2,5-bis(3-tetradecylthiophen-2-yl)thieno[3,2-b]thiophene) (PBTTT-C14) is examined. A combinationof solid-state NMR, synchrotron X-ray scattering, and optical spectroscopywas used to determine the packing motif for blends of PBTTT-C14and F4TCNQ in thin and bulk films. These resultsindicate that F4TCNQ and PBTTT-C14order ina cofacial arrangement where charge transfer is near 100% efficientin the solid state. These results provide crucial insights into thestructures and compositions of ordered domains in doped semiconductingpolymers and suggest a model for the microstructure where the locationof the molecular acceptors are correlated rather than randomly dispersed.
