Policy Dialogue: Online Education as Space and Place
Authors: Pursell Carroll , Iiyoshi Toru 
Published: November 2021

AbstractThe rise of online learning over the past few decades has raised fundamental questions about the kinds of “spaces” and “places” this mode of education creates. Do they support meaningful exchanges? Can they advance educational equity, access, and community-building? Are they comparable to in-person classroom experiences? The recent COVID pandemic and the global turn toward virtual learning in response have brought such questions into sharp relief. These were the questions and contextual factors that brought distinguished historian Carroll Pursell and international educational technology authority Toru Iiyoshi together for this policy dialogue. Their conversation takes readers on a wide-ranging discussion about the interplay between education, technology, and society writ large. And they offer insights into the past, present, and likely future of education in an era of accelerating technological change.Carroll Pursell is the Adeline Barry Davee Distinguished Professor of History (Emeritus) at Case Western Reserve University and Distinguished Honorary Professor of History at the Australian National University. He held faculty positions at the University of California at Santa Barbara and served as the Andrew W. Mellon Distinguished Professor of the Humanities at Lehigh University. Pursell is a fellow of the American Association for the Advancement of Science (AAAS), and former president of both the International Committee for the History of Technology (ICOHTEC) and the Society for the History of Technology (SHOT), which also awarded him its Leonardo da Vinci Medal for outstanding contributions to the history of technology.Toru Iiyoshi is professor and director at the Center for the Promotion of Excellence in Higher Education at Kyoto University.

Uptake of coronavirus disease 2019 (COVID-19) vaccination among general hospital staff in Israel
Authors: Myers Vicki , Saban Mor , Ben-Shetrit Shani , Wilf-Miron Rachel 
Published: November 2021

AbstractData from all general hospitals in Israel to April 2021 show that the mean hospital rate of staff vaccination was 84.4% for the first dose and 77.1% for the second dose, which are lower than general population rate, with mean 7% who did not complete their vaccinations. Healthcare workers have an important role in influencing the wider community.
Marketizing Sovereign Prerogatives: How to Sell Citizenship
Authors: Surak Kristin 
Published: November 2021

AbstractHow is a sovereign prerogative brought to market? We know much about how states shape markets and vice versa, but less about the dynamics when states not only set market rules, but are also the sole producer of the good. This article takes up the case of citizenship by investment—“golden passport” programs that offer citizenship in recognition of an investment in a country—to unpack the challenges that appear when states commodify sovereign prerogatives. In these cases, the state holds multiple roles that generate conflicts of interest and a concern for credibility. To address these concerns, states may adopt two strategies: institute a division of labor in issuing the product, and outsource elements of supervision to third-party actors. Empirically, the analysis shows how migration service providers retooled murky discretionary grants of citizenship in peripheral countries into formal citizenship by investment schemes. The conclusion addresses how these strategies apply in markets for other sovereign prerogatives, particularly government debt, and discusses the implications for citizenship and neoliberalism.
The effect of walnut consumption on cardiometabolic profiles of individuals with abnormal glucose homoeostasis: a systematic review and meta-analysis of clinical trials
Authors: Malmir Hanieh , Larijani Bagher , Esmaillzadeh Ahmad 
Published: November 2021

AbstractFindings on the effect of walnut consumption on cardiometabolic profiles in individuals with abnormal glucose homoeostasis are conflicting. We summarised earlier data in this regard. A systematic literature search of relevant reports published in Medline/PubMed, ISI web of Science, EMBASE, SCOPUS and Google Scholar up to October 2020 was conducted. Randomised trials that enrolled individuals with abnormal glucose homoeostasis in which the main intervention was walnut consumption were included. Abnormal glucose homoeostasis was defined as a spectrum of impaired glucose tolerance or pre-diabetic status that is associated with insulin resistance. Twelve studies were included in systematic review and eight in meta-analysis. No significant effect of walnut consumption on anthropometric measures, including weighted mean difference (WMD: −0·13; 95 % CI −0·64, 0·39 kg), BMI (–0·08; 95 % CI −0·47, 0·32 kg/m2) and waist circumference (0·01; 95 % CI −0·50, 0·52 cm) was observed. Although walnut intake did not influence on lipid profiles (including TAG, total- and HDL-cholesterol levels), individuals in the intervention group tended to have lower levels of LDL-cholesterol than those in the control group (–0·10; 95 % CI −0·20, 0·01 mmol/l; P = 0·06). Other cardiometabolic factors including markers of glycaemic control (fasting blood glucose and HbA1C levels), blood pressure and stimulus-adjusted response measure (a parameter of endothelial function) were not significantly affected. However, walnut consumption resulted in a significant increase in flow-mediated dilation (FMD) (0·93 %; 95 % CI 0·16, 1·71 %). Summarising earlier evidence, we found that walnut consumption might influence FMD and LDL-cholesterol levels in individuals with abnormal glucose homoeostasis. It did not affect other cardiometabolic profiles in these individuals.
A Distinct Society? Understanding Social Distrust in Quebec
Authors: Bridgman Aengus , Nadeau Rosalie , Stolle Dietlind 
Published: November 2021

AbstractFollowing public debates on the topic of trust in Quebec, this article examines the alleged social capital differential between Quebec and the rest of Canada. The literature has found lower levels of generalized trust in Quebec, but explanations offered are diverse and conjectural, with historical, sociological and political factors all in contention. We test contextual and compositional influences, including cohort differences, language and linguistic ability, religion, ethnicity, and neighbourhood-level measures of diversity, using pooled cross-sectional data from the Canadian General Social Survey (2003, 2008 and 2013) linked with precise measures of neighbourhood-level ethnic and linguistic diversity drawn from the Canadian census. We identify those Quebecers who have low levels of trust and those who more closely resemble their counterparts in the rest of Canada. We find that individual linguistic ability and linguistic heterogeneity of the neighbourhood are important correlates of trust and that among francophone populations, social distrust is found most in unilingual homogenous communities.
The Urban-Rural Divide in Canadian Federal Elections, 1896–2019
Authors: Armstrong David A. , Lucas Jack , Taylor Zack 
Published: November 2021

AbstractUsing a new measure of urbanity for every federal electoral district in Canada from 1896 to the present, this article describes the long-term development of the urban-rural divide in Canadian federal elections. We focus on three questions: (1)whenthe urban-rural divide has existed in Canada, identifying three main periods—the 1920s, the 1960s and 1993–present—in which the urban-rural cleavage has been especially important in federal elections; (2)wherethe urban-rural divide has existed, finding that in the postwar period the urban-rural cleavage is a pan-Canadian phenomenon; and (3)how wellurbanity predicts district-level election outcomes. We argue that the urban-rural divide is important for understanding election outcomes during several periods of Canadian political development, and never more so than in recent decades. We conclude by discussing the implications of our findings for research on urban-rural cleavages, Canadian electoral politics and Canadian political development.
The oldest-known Lestidae (Odonata) from the late Eocene of Tibet: palaeoclimatic implications

Published: November 2021

AbstractTerrestrial fossils from the Palaeogene of Tibet could help us to better understand the past climate and environment in this area. We herein report a new late Eocene non-marine fossil site from southern Nima Basin, central Tibet, SW China, including abundant insects and fishes. These fossils are similar to those from the late Eocene (∼39.5–37 Ma) Lunpola–Nima sediment depo-centres in sharing the dominating aquatic bug Aquarius lunpolaensis and cyprinid fishes. Chalcolestes tibetensis sp. nov., the oldest representative of the modern family Lestidae, is described. Lestidae were previously only recorded in Western Europe, and the oldest records were from the uppermost Eocene of France and the UK. The present discovery demonstrates that Lestidae already had a broad distribution during the Eocene and probably originated much earlier. The recent representatives of Chalcolestes occur in the low-altitude ponds or lakes of Western Palaearctic. Together with the other freshwater fossils in this site, this new discovery indicates a humid climate and low altitude for the Nima Basin and nearby basins in the middle part of the Bangong Nujiang suture zone.
Active Technological Similarity and Mutual Fund Performance
Authors: McLemore Ping , Sias Richard , Wan Chi , Yüksel H. Zafer 
Published: November 2021

AbstractWe examine whether superior understanding of technological innovation is a source of mutual fund managers’ ability to garner positive abnormal returns. Consistent with our hypothesis, the inter-quintile annual net Carhart alpha spread for mutual funds sorted on changes in the technological similarity (TS) of their portfolio holdings is 282 basis points. Moreover, because changes in TS are largely orthogonal to other predictors of mutual fund success (e.g., industry concentration, active share, fund R2, and lag fund alpha), changes in TS can be combined with other measures to help identify the best performing funds.
Interactions of the Trypanosoma brucei brucei zinc-finger-domain protein ZC3H28
Authors: Bishola Tshitenge Tania , Clayton Christine 
Published: November 2021

AbstractIn Trypanosoma brucei and related Kinetoplastids, regulation of gene expression occurs mostly post-transcriptionally, and RNA-binding proteins play a critical role in the regulation of mRNA and protein abundance. Trypanosoma brucei ZC3H28 is a 114 KDa cytoplasmic mRNA-binding protein with a single C(x)7C(x)5C(x)sH zinc finger at the C-terminus and numerous proline-, histidine- or glutamine-rich regions. ZC3H28 is essential for normal bloodstream-form trypanosome growth, and when tethered to a reporter mRNA, ZC3H28 increased reporter mRNA and protein levels. Purification of N-terminally tagged ZC3H28 followed by mass spectrometry showed enrichment of ribosomal proteins, various RNA-binding proteins including both poly(A) binding proteins, the translation initiation complex EIF4E4/EIF4G3, and the activator MKT1. Tagged ZC3H28 was preferentially associated with long RNAs that have low complexity sequences in their 3′-untranslated regions; their coding regions also have low ribosome densities. In agreement with the tethering results, after ZC3H28 depletion, the levels of a significant proportion of its bound mRNAs decreased. We suggest that ZC3H28 is implicated in the stabilization of long mRNAs that are poorly translated.
‘A very exclusive experiment in communism’: the radical origins of the Manhattan co-op
Authors: Masterson Jack T. 
Published: November 2021

AbstractThough it has long been the residence of choice for Manhattan's rich, the co-operative apartment building has an intellectual lineage that originates in pre-Marxian communitarian socialism. In the early nineteenth century, radical philosophers Charles Fourier and Robert Owen first theorized a multifamily dwelling owned in joint stock by its residents that could deliver economies of scale in the production and delivery of household necessities. Using previously untranslated French sources and archival material (New Harmony Working Men's Institute), this article demonstrates how early socialist ideas about housing, domestic labour and ownership evolved into the idea for the New York City co-operative apartment building.
The Ptolemy Painting? Alexander's “right-hand man” and the origins of the Alexander Mosaic
Authors: Thomas Joshua J. 
Published: November 2021

AbstractThis article revisits the origins of the Alexander Mosaic at Pompeii by focusing on the figure standing at Alexander's right hand. The starting point is Andreas Rumpf's suggestion that this “right-hand man” may be the patron of the original painting, who wished to advertise his own role in the represented battle. It is argued that Ptolemy I is perhaps the strongest candidate on historical grounds, and that interesting connections can be drawn between the mosaic and the historian Kleitarchos, who worked at the Ptolemaic court. Circumstantial support for a Ptolemaic connection is supplied by other finds from the House of the Faun, three of which are briefly re-examined.
EMS at 3600 Meters: Exploring Barriers to Emergency Care and Transport in Rural Andean Perú
Authors: Vasa Alison H. , Falkenstein Karen A. , Centrone Wayne A. 
Published: November 2021

AbstractBackground:Given the demonstrated success of programs that bolster informal Emergency Medical Service (EMS) systems in other low- and middle-income counties (LMICs), this study aimed to explore formal and informal systems, practices, customs, and structures for emergency response and medical transport in Colca Valley, Perú while identifying possible opportunities for future intervention.Methods:Twenty-two interviews with first responders and community members were conducted in three mountain villages throughout rural Andean Colca Valley of Perú. Subjects were recruited based on profession and experience with medical emergencies in the area. Transcripts were entered into Dedoose, coded, and analyzed to identify themes.Results:Providers and community members shared similar perceptions on the most common barriers to emergency care and transport. Challenges experienced equally by both groups were identified as “structural problems,” such as lack of infrastructure, lack of structured care delivery, and unclear protocols.Incongruities of responses between groups emerged with regard to certain barriers to care. Providers perceived baseline health education and use of home remedies as significant barriers to seeking care, which was not proportionally corroborated by community members. In contrast, 86% of community members cited lack of trust in health providers as a major barrier.Community members often noted witnessing a high frequency of emergency events, their personal experiences of helping, and the formal utilization of lay providers. When specifically questioned on their willingness to engage in first aid training, all participants were in agreement.Conclusion:While structural changes such as increased infrastructure would likely be the most durable improvement, future interventions focused on both empowering community members and improving the relationship between the health center and the community would be beneficial in this community. Additionally, these interview data suggest that a layperson first aid training program would be feasible and well-received.
Sentence encoding for Dialogue Act classification
Authors: Duran Nathan , Battle Steve , Smith Jim 
Published: November 2021

AbstractIn this study, we investigate the process of generating single-sentence representations for the purpose of Dialogue Act (DA) classification, including several aspects of text pre-processing and input representation which are often overlooked or underreported within the literature, for example, the number of words to keep in the vocabulary or input sequences. We assess each of these with respect to two DA-labelled corpora, using a range of supervised models, which represent those most frequently applied to the task. Additionally, we compare context-free word embedding models with that of transfer learning via pre-trained language models, including several based on the transformer architecture, such as Bidirectional Encoder Representations from Transformers (BERT) and XLNET, which have thus far not been widely explored for the DA classification task. Our findings indicate that these text pre-processing considerations do have a statistically significant effect on classification accuracy. Notably, we found that viable input sequence lengths, and vocabulary sizes, can be much smaller than is typically used in DA classification experiments, yielding no significant improvements beyond certain thresholds. We also show that in some cases the contextual sentence representations generated by language models do not reliably outperform supervised methods. Though BERT, and its derivative models, do represent a significant improvement over supervised approaches, and much of the previous work on DA classification.
Defeasible Reasoning via Datalog¬
Authors: MAHER MICHAEL J. 
Published: November 2021

AbstractWe address the problem of compiling defeasible theories to Datalog¬ programs. We prove the correctness of this compilation, for the defeasible logic DL(∂||), but the techniques we use apply to many other defeasible logics. Structural properties of DL(∂||) are identified that support efficient implementation and/or approximation of the conclusions of defeasible theories in the logic, compared with other defeasible logics. We also use previously well-studied structural properties of logic programs to adapt to incomplete Datalog¬ implementations.
VeriFly: On-the-fly Assertion Checking via Incrementality
Authors: SANCHEZ-ORDAZ MIGUEL A. , GARCIA-CONTRERAS ISABEL , PEREZ VICTOR , MORALES JOSÉ F. , LOPEZ-GARCIA PEDRO , HERMENEGILDO MANUEL V. 
Published: November 2021

AbstractAssertion checking is an invaluable programmer’s tool for finding many classes of errors or verifying their absence in dynamic languages such as Prolog. For Prolog programmers, this means being able to have relevant properties, such as modes, types, determinacy, nonfailure, sharing, constraints, and cost, checked and errors flagged without having to actually run the program. Such global static analysis tools are arguably most useful the earlier they are used in the software development cycle, and fast response times are essential for interactive use. Triggering a full and precise semantic analysis of a software project every time a change is made can be prohibitively expensive. This is specially the case when complex properties need to be inferred for large, realistic code bases. In our static analysis and verification framework, this challenge is addressed through a combination of modular and incremental (context- and path-sensitive) analysis that is responsive to program edits, at different levels of granularity. In this tool paper, we present how the combination of this framework within an integrated development environment (IDE) takes advantage of such incrementality to achieve a high level of reactivity when reflecting analysis and verification results back as colorings and tooltips directly on the program text – the tool’s VeriFly mode. The concrete implementation that we describe is Emacs-based and reuses in part off-the-shelf “on-the-fly” syntax checking facilities (flycheck). We believe that similar extensions are also reproducible with low effort in other mature development environments. Our initial experience with the tool shows quite promising results, with low latency times that provide early, continuous, and precise assertion checking and other semantic feedback to programmers during the development process. The tool supports Prolog natively, as well as other languages by semantic transformation into Horn clauses.
“Vote for your Bread and Butter”: Economic Intimidation of Voters in the Gilded Age
Authors: Cohn-Postar Gideon 
Published: November 2021

AbstractThe extent and intensity of electoral and voter fraud that took place during the U.S. Gilded Age is properly infamous. This paper explores a form of voter intimidation that has garnered comparatively little scholarly attention: economic coercion. Absent secrecy at the polls and security at work, bosses forced workingmen to choose between their job or their vote. Economic voter intimidation provoked both a real and rhetorical crisis in the 1870s and 1880s. In real terms, it disrupted hundreds of elections and damaged thousands of workers’ livelihoods. It became a nationwide crisis after 1873, however, because for the first time, employers were coercing white workingmen on a widespread basis. Reports of employers coercing their employees at the polls throughout the nation confirmed the worst fears of many labor leaders and politicians: white wage-workers were insecure possessors of the franchise whose precariousness might threaten democracy itself. Mining previously overlooked accounts of economic voter intimidation in contested congressional election case records, congressional investigations, corporate records, and newspapers, this article argues that employers’ politicized layoff threats and observation of workers at the polls undermined the political equality of even those men whose whiteness had seemingly secured their privilege.
Alternative methods for terminating green manures in organic grain systems
Authors: Pickoff Margaret , Mallory Ellen B. , Molloy Thomas 
Published: November 2021

AbstractLegume green manures (GM) are a vital source of nitrogen (N) for many organic grain systems. A common practice among organic growers is to undersow clover into a small grain, harvest the grain crop and terminate the clover stand in late fall by moldboard plowing in preparation for a cash crop the following spring. While fall plowing offers excellent clover kill, growers increasingly seek an alternative termination method that reduces tillage intensity and bare winter soil. This study, performed at two sites in Maine, evaluates three clover termination methods for kill efficacy, winter soil cover, spring soil conditions and N uptake and grain yield and protein of a subsequent test crop of hard red spring wheat (Triticum aestivum L., var. Glenn). Red clover (Trifolium pratense L.) was intercropped with spring barley (Hordeum vulgare L.) and terminated in late fall by moldboard plowing (PL), skim plowing (SK) or undercutting (UC). A control treatment received no clover and was fall plowed. An additional treatment, winterkilled field peas (WK), was evaluated at one site. SK, UC and WK increased soil cover relative to PL, though UC resulted in low clover kill efficacy in a wet spring and is in need of improved design. Grain yield was higher following red clover compared to the no-clover control at one site, but was unaffected by termination method. At one site, grain crude protein was higher following PL than the other treatments, indicating the possibility for more favorable timing of N availability associated with PL.
