Demophilia: A Discursive Counter to Demophobia in the Early Republic

The term “democracy” is ambivalent—in the history of the United States, it has played both god term and devil term, and inspired both sacrifice and trembling. Robert L. Ivie has mapped the discourse by which American policy elites have said “no” to democracy—the rhetoric of “demophobia.” This essay complements his analysis by mapping the discourse by which Americans began to say “yes” to democracy during President Thomas Jefferson's administration—the rhetoric of “demophilia.” Understood as a discursive formation, demophilia creates space for rhetoric and deliberation that is closed by demophobia. In the process, demophilia disciplines democracy by producing deliberative subjects properly attuned to civil speech.     

“The Effort of Reason,and the Adventure of Beauty”: The Aesthetic Rhetoric of Randolph Bourne

We are still coming to terms with the legacy of Randolph Bourne. Although he died at the age of 32 just as the United States was cheerfully entering the First World War under the banner of “democracy,” the words he penned in an unfinished essay still resonate in the American social conscience: “War is the Health of the State.” This maxim, once thought the exclusive property of leftist radicals, now can be heard echoing from every political corner of the blogosphere as progressives and libertarians alike find cause to question the motives of governmental power. Yet despite his reappearance as a symbol, Bourne in many ways remains as forgotten as ever—perhaps even more so as his once provocative claim has been transformed into a talking point. This essay endeavors to recapture the voice of Bourne in all its complexity, seeking to place him at the forefront of the contemporary American intellectual tradition as one of its most piercing critics, most visionary poets, and most eloquent rhetors. Specifically, we show how Bourne's critique of the “State” foresaw the rise of the technological society organized by ideological propaganda, how his vision of the Beloved Community anticipated our modern ideals of global transnationalism, and how his literary essays practiced a form of aesthetic rhetoric which employed dramatistic methods to bring about a new state of expanded social consciousness.     

EDUCATING MEN WITH REFERENCE TO SOCIAL LEGISLATION

Abstract

A paramount task of religious education should be the exposing and redressing of social injustice. Two of the pervasive and perduring evils of our time are sexism and racism. With their insights into theological authenticity and their skills in both shaping attitudes and inspiring actions, religious educators are in potent positions to effect liberationist change. To do so, they must become comprehensively informed and profoundly committed. They must become transformed teachers of transforming truth.

I have looked at the South's beautiful churches with their lofty spires pointing heavenward. I have beheld the impressive outlines of their massive religious education buildings. Over and over I found myself asking, What kind of people worship here? Who is their God?     

Impact of the choice of threshold on physical activity patterns in free living conditions among adolescents measured using a uniaxial accelerometer: The HELENA study

Abstract

The aim of this study was to assess the impact of the choice of threshold on physical activity patterns measured in adolescents under free living conditions (FLC) using a uniaxial accelerometer. The study comprised 2043 adolescents (12.5–17.5 years) participating in the HELENA Study. Participants wore a uniaxial accelerometer for 7 days. The PA patterns were assessed using thresholds determined from six different studies. For each of the thresholds used, the number of adolescents fulfilling the recommendation of 60 min of moderate to vigorous PA (MVPA) per day was also calculated. A significant difference was found between thresholds regardless of the activity level: differences of 38%, 207%, 136%, and 2780% for sedentary, light, moderate, and vigorous intensity PA, respectively (P < 0.001). Time of MVPA varied between methods from 25.3 to 55.2 min · day^–1. The number of adolescents fulfilling the recommendation varied from 5.9% to 37% according to the thresholds used. The kappa coefficient for concordance in the assessment of the number of adolescents achieving the PA recommendations was generally low. The definition of the threshold for PA intensity may considerably affect the PA patterns in FLC when assessed using a uniaxial accelerometer and the number of participants fulfilling the recommendations.     

Development of an accelerometer-based multivariate model to predict free-living energy expenditure in a large military cohort

Abstract

This study developed a multivariate model to predict free-living energy expenditure (EE) in independent military cohorts. Two hundred and eighty-eight individuals (20.6 ± 3.9 years, 67.9 ± 12.0 kg, 1.71 ± 0.10 m) from 10 cohorts wore accelerometers during observation periods of 7 or 10 days. Accelerometer counts (PAC) were recorded at 1-minute epochs. Total energy expenditure (TEE) and physical activity energy expenditure (PAEE) were derived using the doubly labelled water technique. Data were reduced to n = 155 based on wear-time. Associations between PAC and EE were assessed using allometric modelling. Models were derived using multiple log-linear regression analysis and gender differences assessed using analysis of covariance. In all models PAC, height and body mass were related to TEE (P < 0.01). For models predicting TEE (r ² = 0.65, SE = 462 kcal · d^?1 (13.0%)), PAC explained 4% of the variance. For models predicting PAEE (r ² = 0.41, SE = 490 kcal · d^?1 (32.0%)), PAC accounted for 6% of the variance. Accelerometry increases the accuracy of EE estimation in military populations. However, the unique nature of military life means accurate prediction of individual free-living EE is highly dependent on anthropometric measurements.     

How learning in an inverted classroom influences cooperation, innovation and task orientation

Recent technological developments have given rise to blended learning classrooms. An inverted (or flipped) classroom is a specific type of blended learning design that uses technology to move lectures outside the classroom and uses learning activities to move practice with concepts inside the classroom. This article compares the learning environments of an inverted introductory statistics class with a traditional introductory statistics class at the same university. This mixed-methods research study used the College and University Classroom Environment Inventory (CUCEI), field notes, interviews and focus groups to investigate the learning environments of these two classrooms. Students in the inverted classroom were less satisfied with how the classroom structure oriented them to the learning tasks in the course, but they became more open to cooperative learning and innovative teaching methods. These findings are discussed in terms of how they contribute to the stability and connectedness of classroom learning communities.     

Using comparative genomics for inquiry-based learning to dissect virulence of Escherichia coli O157:H7 and Yersinia pestis

Genomics and bioinformatics are topics of increasing interest in undergraduate biological science curricula. Many existing exercises focus on gene annotation and analysis of a single genome. In this paper, we present two educational modules designed to enable students to learn and apply fundamental concepts in comparative genomics using examples related to bacterial pathogenesis. Students first examine alignments of genomes of Escherichia coli O157:H7 strains isolated from three food-poisoning outbreaks using the multiple-genome alignment tool Mauve. Students investigate conservation of virulence factors using the Mauve viewer and by browsing annotations available at the A Systematic Annotation Package for Community Analysis of Genomes database. In the second module, students use an alignment of five Yersinia pestis genomes to analyze single-nucleotide polymorphisms of three genes to classify strains into biovar groups. Students are then given sequences of bacterial DNA amplified from the teeth of corpses from the first and second pandemics of the bubonic plague and asked to classify these new samples. Learning-assessment results reveal student improvement in self-efficacy and content knowledge, as well as students' ability to use BLAST to identify genomic islands and conduct analyses of virulence factors from E. coli O157:H7 or Y. pestis. Each of these educational modules offers educators new ready-to-implement resources for integrating comparative genomic topics into their curricula.
