AbstractActive 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. 相似文献

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 (Cm) 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 Cm value is a conservative estimate considering that the extraction process was not fully optimized by this study, which was not necessary since the Cm 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. 相似文献

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. 相似文献

This paper asks whether strong bureaucracies can effectively constrain the continuously growing stock of rules in modern democracies through organizational coordination and learning. To answer this question, the paper analyzes the growth of rule stocks in the areas of environmental policy and social policy in 23 OECD countries over the period between 1976 and 2005. To do so, it develops a new measure of rule growth based on the content of laws and regulations rather than their length. The analysis highlights that effective bureaucracies are indeed better able to contain rule growth in these areas than weak bureaucracies. Since rules have to be implemented, countries suffering from bureaucratic capacity and quality constraints thus appear to be stuck in an implementation deficit trap. Appropriate implementation is not only inherently more challenging for countries with weak public administrations, but the body of rules to be implemented also tends to grow quicker in these countries. 相似文献

We develop front‐door difference‐in‐differences estimators as an extension of front‐door estimators. Under one‐sided noncompliance, an exclusion restriction, and assumptions analogous to parallel trends assumptions, this extension allows identification when the front‐door criterion does not hold. Even if the assumptions are relaxed, we show that the front‐door and front‐door difference‐in‐differences estimators may be combined to form bounds. Finally, we show that under one‐sided noncompliance, these techniques do not require the use of control units. We illustrate these points with an application to a job training study and with an application to Florida's early in‐person voting program. For the job training study, we show that these techniques can recover an experimental benchmark. For the Florida program, we find some evidence that early in‐person voting had small positive effects on turnout in 2008. This provides a counterpoint to recent claims that early voting had a negative effect on turnout in 2008. 相似文献

A legislator’s duty is to vote on legislation, yet legislators routinely miss votes. Existing studies of absenteeism have focused on the US Congress, producing useful but partial explanations. We provide added insight by examining absenteeism in American state legislatures. Our data include 2,916,471 individual votes cast by 4392 legislators from 64 legislative chambers. This rich, multistate dataset produces insights that build on and sometimes conflict with Congressional research. We use a multilevel logistic model with nested and crossed random effects to estimate the influence of variables at five different levels. In particular, we investigate whether state legislators miss unimportant votes or important votes. Contrary to what Congressional studies have found, we find that state legislators avoid participating in close or major votes, favoring reelection concerns over policy influence. We also find that state-to-state variations in legislative professionalism—in particular, the length of the session—affect absenteeism, with shorter sessions leading to higher absenteeism. 相似文献
