Lecture Versus Simulation: Testing the Long-Term Effects

Abstract

Active learning techniques are being use with increasing frequency in the classroom and more time is being dedicated to designing and implementing them. However, the literature still suffers from a lack of rigorous empirical methods to test the effects of simulations. Most of the claimed benefits of utilizing simulations, and other active learning techniques, are improved soft skills and higher order thinking like empathy, confidence, public-speaking abilities, and interpersonal skills—all of which don’t lend themselves well to scientific measurement. This gap in the literature is especially troubling considering that time spent using simulations is time not spent using other methods. This article seeks to test the differing impacts of simulations versus traditional lectures over the long-term using a simple 30-minute simulation and rigorous experimental methods. The most important results show that students learn more initially from a lecture, but that students who were exposed to the simulation were better able to retain that information over the long-term.

Detection of Mitragynine in Mitragyna Speciosa (Kratom) Using Surface-Enhanced Raman Spectroscopy with Handheld Devices

A simple, quick, selective, sensitive, and effective field-friendly method capable of being used by nonexperts has been developed for detecting mitragynine in Mitragyna speciosa (kratom) using surface-enhanced Raman spectroscopy (SERS). Over 100 samples and blanks (known to be either positive or negative for the presence of mitragynine) were examined in duplicate using five identical handheld Raman spectrometers, which provided a data set of over 1,000 examinations. Based on the results of these analyses, the method yielded a true-positive rate of 99.3%, a true-negative rate of 97.9%, a false-positive rate of 2.1%, and a false-negative rate of 0.7%. The average minimum detectable concentration (C_m) of mitragynine that reproducibly yielded a match for one of the library spectra on all five instruments was determined to be 342 ng/mL (ppb). This C_m value is a conservative estimate considering that the extraction process was not fully optimized by this study, which was not necessary since the C_m value achieved was well below typical mitragynine concentrations in kratom (1.3–2.3%). The method is ideal (i) for prioritizing samples for additional testing using other more time-consuming laboratory-based techniques needed to detect and quantify mitragynine and (ii) for field use at international mail facility (IMF) satellite laboratories to help interdict kratom and prevent this dangerous product from reaching the U.S. supply chain.     

Perceptions of Problem Behavior in Adolescents’ Families: Perceiver,Target, and Family Effects

Considerable research has focused on the reliability and validity of informant reports of family behavior, especially maternal reports of adolescent problem behavior. None of these studies, however, has based their orientation on a theoretical model of interpersonal perception. In this study we used the social relations model (SRM) to examine family members’ reports of each others’ externalizing and internalizing problem behavior. Two parents and two adolescents in 69 families rated each others’ behavior within a round-robin design. SRM analysis showed that within-family perceptions of externalizing and internalizing behaviors are consistently due to three sources of variance; perceiver, target, and family effects. A family/contextual effect on informant reports of problem behavior has not been previously reported.     

Structural reform histories and perceptions of organizational autonomy: Do senior managers perceive less strategic policy autonomy when faced with frequent and intense restructuring?

Through recurrent structural reform programmes governments are on a quest to design public organizations that will stand the test of their environment. One of the approaches to uncertain or sensitive issues has been to create various forms of (semi‐)autonomous organizations with substantial strategic discretion. However, while governments repeatedly experiment with designs, one might simultaneously expect that such interference through repeated structural change may limit the degree of strategic policy autonomy perceived by senior managers. More specifically, we propose that intense structural reforms may inadvertently reduce strategic policy autonomy perceptions through two mechanisms. First, intense sequences of structural reforms may lead to perceptions of relatively controlling political principals. Second, they may reduce an organization's ability to accrue resources beneficial to autonomy, such as a strong internal culture, network embeddedness and expertise. Results indicate that strategic policy autonomy perceptions will indeed be detrimentally affected for organizations that experience intense sequences of structural reform.     

State,Society, and Informality in Cities of the Global South

Contemporary urbanization in the Global South merits greater attention from scholars of comparative politics. Governance, associational life, and political behavior take distinctive forms in the social and institutional environments created by rapid urbanization, particularly within informal settlements and labor markets. In this special issue, we examine forms of collective action and claims-making in these spaces. We also consider how the state assesses, maps, and responds to the demands of informal sector actors. Tackling questions of citizen and state behavior in these informal urban contexts requires innovative research strategies due to data scarcity and social and institutional complexity. Contributors to this symposium offer novel strategies for addressing these challenges, including the use of informal archives, worksite-based sampling, ethnographic survey design, enforcement process-tracing, and crowd-sourced data.
