No evidence of fetal defects or anti-syncytin-1 antibody induction following COVID-19 mRNA vaccination.

The impact of Coronavirus Disease 2019 (COVID-19) mRNA vaccination on pregnancy and fertility has become a major topic of public interest. We investigated 2 of the most widely propagated claims to determine (1) whether COVID-19 mRNA vaccination of mice during early pregnancy is associated with an increased incidence of birth defects or growth abnormalities; and (2) whether COVID-19 mRNA-vaccinated human volunteers exhibit elevated levels of antibodies to the human placental protein syncytin-1. Using a mouse model, we found that intramuscular COVID-19 mRNA vaccination during early pregnancy at gestational age E7.5 did not lead to differences in fetal size by crown-rump length or weight at term, nor did we observe any gross birth defects. In contrast, injection of the TLR3 agonist and double-stranded RNA mimic polyinosinic-polycytidylic acid, or poly(I:C), impacted growth in utero leading to reduced fetal size. No overt maternal illness following either vaccination or poly(I:C) exposure was observed. We also found that term fetuses from these murine pregnancies vaccinated prior to the formation of the definitive placenta exhibit high circulating levels of anti-spike and anti-receptor-binding domain (anti-RBD) antibodies to Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) consistent with maternal antibody status, indicating transplacental transfer in the later stages of pregnancy after early immunization. Finally, we did not detect increased levels of circulating anti-syncytin-1 antibodies in a cohort of COVID-19 vaccinated adults compared to unvaccinated adults by ELISA. Our findings contradict popular claims associating COVID-19 mRNA vaccination with infertility and adverse neonatal outcomes.

“Reason to know” in the international law of command responsibility

AbstractA recent report by the Australian Defence Force arrived at a conclusion that further investigation was not warranted of commanders regarding their responsibility for failing to investigate suspicious behaviour of subordinates in Afghanistan, who were accused of violations of international humanitarian law. This troubling conclusion calls for a better analysis and understanding of command responsibility in international law and gaps in the law of command responsibility. This article identifies the conflicting precedents and scholarship regarding the law of command responsibility, which create uncertainty, and proposes a clarification of that law, with a special focus on the “reason to know” standard that triggers responsibility for failing to prevent or punish war crimes. It refutes the popular claim that commanders must act wilfully, and it rejects the common dichotomy between a commander who orders or otherwise directly participates in the war crimes of subordinates and one who unwittingly fails to prevent or punish such crimes. Using the empirical psychological literature, the article further explains how commanders can insidiously signal toleration of war crimes without giving direct orders. Finally, the article argues that international law, by absolving commanders who fail to properly train their subordinates to respect the law of armed conflict, misses a rare opportunity to deter war crimes, and offers some suggestions to fill this gap in the law.

The politics of radical interdependence in critical pedagogies: A non-alternative context for CAMPUS at Nottingham Contemporary

The past fifteen years have seen a rich debate situating the curatorial in the expanded field of exhibition-making, towards dialogical and discursive formats. Under the umbrella term the ‘educational turn’, pedagogical programmes have explored classroom aesthetics and the emancipatory potentials of pedagogy in the arts and curating – within and outside arts institutions. This article investigates the relevance of such pedagogical programmes in the cultural sector that aim to generate an open resource for long-term critical debates and collective thinking. The article reflects on the role of cultural institutions in wider discussions around the neo-liberalization of formal education and the political potentials of new pedagogical initiatives. It draws on decolonial problem-posing pedagogy to counter the increasing cultures of anti-intellectualism and anti-complexity in the United Kingdom (UK). The text reflects upon the experience of the CAMPUS Independent Study Programme, I curated in 2019–20 at Nottingham Contemporary, a contemporary art centre in the United Kingdom. Contrary to the popular claim for alterity and outsideness, this article demonstrates the political role of embeddedness and radical interdependence in critical pedagogical initiatives in contemporary art institutions.

Soil biodiversity and nature-mimicry in agriculture; the power of metaphor?

Attention to soil biodiversity and its importance for sustainable food production has markedly increased in recent years. In particular, the loss of soil biodiversity as a consequence of intensive agriculture, land degradation and climate change has raised concerns due to the expected negative impacts on ecosystem services, food security and human health. The result is a strong demand for ‘nature-based’ practices that stimulate soil biodiversity or beneficial soil organisms and enhance soil health. Here, we examine the origin of popular ideas on the role of soil biology in sustainable soil management, as well as their potential to address key global challenges related to agriculture. Three examples of such ideas are discussed: 1) a higher fungal:bacterial (F:B) biomass ratio favours soil carbon storage and nutrient conservation; (2) intensive agricultural practices lead to a decline in soil biodiversity with detrimental consequences for sustainable food production; (3) inoculation with arbuscular mycorrhizal fungi reduces agriculture's dependency on synthetic fertilizers. Our analysis demonstrates how ecological theories, especially E.P. Odum's ( 1969 ) hypotheses on ecological succession, have inspired the promotion of agricultural practices and commercial products that are based on the mimicry of (soil biology in) natural ecosystems. Yet our reading of the scientific literature shows that popular claims on the importance of high F:B ratios, soil biodiversity and the inoculation with beneficial microbes for soil health and sustainable agricultural production cannot be generalized and require careful consideration of limitations and possible trade-offs. We argue that dichotomies and pitfalls associated with the normative use of nature as a metaphor for sustainability can be counterproductive given the urgency to achieve real solutions that sustain food production and natural resources. Finally, implications for soil ecology research and sustainable soil management in agriculture are discussed.

Political Polarization and Social Media

A popular claim is that social media is a cause of contemporary high levels of political polarization. In this paper, I consider three of the most common kinds of arguments for the thesis. One type lays out a narrative of causes, tracing the causal steps between logging on to social media and later becoming more polarized. Another type uses computer modeling to show how polarized effects can arise from systems that are analogous to use of social media. The final type considers straightforward experimental evidence for the polarizing effect. I reject each of these arguments and explain why they are unconvincing.

Infodemiological Examination of Personal and Commercial Tweets About Cannabidiol: Term and Sentiment Analysis.

BackgroundIn the absence of official clinical trial information, data from social networks can be used by public health and medical researchers to assess public claims about loosely regulated substances such as cannabidiol (CBD). For example, this can be achieved by comparing the medical conditions targeted by those selling CBD against the medical conditions patients commonly treat with CBD.ObjectiveThe objective of this study was to provide a framework for public health and medical researchers to use for identifying and analyzing the consumption and marketing of unregulated substances. Specifically, we examined CBD, which is a substance that is often presented to the public as medication despite complete evidence of efficacy and safety.MethodsWe collected 567,850 tweets by searching Twitter with the Tweepy Python package using the terms “CBD” and “cannabidiol.” We trained two binary text classifiers to create two corpora of 167,755 personal use and 143,322 commercial/sales tweets. Using medical, standard, and slang dictionaries, we identified and compared the most frequently occurring medical conditions, symptoms, side effects, body parts, and other substances referenced in both corpora. In addition, to assess popular claims about the efficacy of CBD as a medical treatment circulating on Twitter, we performed sentiment analysis via the VADER (Valence Aware Dictionary for Sentiment Reasoning) model on the personal CBD tweets.ResultsWe found references to medically relevant terms that were unique to either personal or commercial CBD tweet classes, as well as medically relevant terms that were common to both classes. When we calculated the average sentiment scores for both personal and commercial CBD tweets referencing at least one of 17 medical conditions/symptoms terms, an overall positive sentiment was observed in both personal and commercial CBD tweets. We observed instances of negative sentiment conveyed in personal CBD tweets referencing autism, whereas CBD was also marketed multiple times as a treatment for autism within commercial tweets.ConclusionsOur proposed framework provides a tool for public health and medical researchers to analyze the consumption and marketing of unregulated substances on social networks. Our analysis showed that most users of CBD are satisfied with it in regard to the condition that it is being advertised for, with the exception of autism.

Effects of consumption of coconut oil or coconut on glycemic control and insulin sensitivity: A systematic review and meta-analysis of interventional trials

Background and aimsThe often purported claim that coconut fat is beneficial for cardiovascular health and was disputed in several recent meta-analyses. However, the evidence on the effects of coconut fat intake on glycemic control remains equivocal. We conducted a systematic review and meta-analysis in accordance with the PRISMA guidelines to determine the effects of dietary coconut fats on markers of acute and long-term glycemic control. Methods and resultsPubMed, Scopus, ProQuest, and Web-of-Science databases were searched and the records were screened by three independent reviewers to identify interventional studies examining acute and long-term (i.e., >10 days) effects of coconut fat on glycemic control. DerSimonian–Laird random-effects meta-analyses were performed using the meta-package in R (4.0.2). Seven interventional studies on acute effects and 11 interventional studies on long-term effects of coconut fat were included. Meals with coconut fat acutely increased the incremental area under the curve (AUC) of glucose (p = 0.046) and decreased the incremental AUC of insulin (p = 0.037) vs. control meals. Long-term coconut fat intake increased HOMA-IR (p = 0.049), but did not significantly affect fasting glucose, insulin, or HOMA-β vs. control meals. ConclusionsCoconut fat in meals seems to be associated with a diminished postprandial insulin response, resulting in a subtle increase in the postprandial glycemic response. Long-term intake of coconut fat seems to increase insulin resistance, yet does not seem to be beneficial for long-term glycemic control. Thus, our results disprove the popular claim that coconut fat improves glycemic control. RegistrationPROSPERO registry (CRD42020183450).

Why Paul doesn't mention the ‘age to come’

AbstractThis essay examines the popular claim that the apostle Paul deploys an apocalyptic ‘two-age’ scheme in his eschatology, adapted from Jewish apocalyptic thought but reworked in an ‘inaugurated’ configuration in his theology as ‘now and not yet’. This reading is challenged as representing an oversimplified and anachronistic reading of the Jewish apocalyptic literature, and in respect of its claim to be a Pauline innovation. Furthermore, it is a reading not adequately sensitive to the fact that Paul rarely (if ever) uses the phrase ‘age to come’. The second section of the essay examines this Pauline evidence, and some of the language Paul uses instead of this phrase. Finally, the essay closes with a theological proposal for why Paul might do this, and makes some suggestions regarding Paul's view of time, the relationship between time and eternity, and possible ways this might be articulated once dogmatically located within his christology.

A Change in Interpersonal Relational Capital: Through mentoring relationships and homework activities in a university setting

This article presents an innovative project revolving around student participation in homework activities. The theoretical framework is relational pedagogy with a focus on student-mentor relationships in a university setting. The authors used semi-structured interviews combined with observations of the interactions between the participants. The findings are analysed at a micro- and meso-level, based on an interpersonal relational perspective on teaching, Pedagogical Relational Teachership (PeRT). The popular claim that homework time is positively related to scholastic achievements gains was observed. The findings from this study add to the general knowledge of how participants perceive their school activities and future careers. Furthermore, relational values like connecting, belonging, trusting, including and confidence-building emerged between students and mentors over time. The examination of the mentor-student relationships highlights how a new interpersonal relational capital launched a movement with a possible change in social position, in terms of entering future university studies. The article discusses the results at a societal level in relation to equity and young people’s possibilities of participating in future university studies. Since the study shows the positive aspects of ‘enriching’ activities supporting immigrant youth in homework activities at university facilities, we encourage other institutions of higher education to open up their premises for similar projects, in order to improve engagement, raise achievement levels and enhance inclusiveness in the larger social fabric.

Beyond data protection concerns – the European passenger name record system

ABSTRACT In this article, we examine the European framework of collecting and analysing flight passenger name record (PNR) data for the purpose of combating terrorism and serious crime. The focus is mainly on the EU PNR Directive of 2016, but we also consider the specific legislative framework in Germany and Denmark. In light of the recent review of the Directive, the article aims at exploring the policy-related, legal and technological challenges. In doing so, it goes beyond established data protection concerns. In particular, we debunk the popular claim that PNR analysis in and of itself entails the risk of discrimination of certain groups – a claim commonly levelled against algorithmic analysis. We also provide useful insights into the specific legal safeguards vis-à-vis automated profiling and decision-making through human review.

Trust in fairness, doping, and the demand for sports: a study on international track and field events

ABSTRACT Research question We investigate empirically the impact of spectators' trust in fairness of the sporting competition on TV demand for sports as well as its role in the doping-demand relation. Research methods We use data from a two-wave panel survey and a sporting event scenario where doping issues are present. The effects are estimated using Zero-Inflated Poisson regressions and radius matching based on the propensity score. Results and findings Results of the panel survey analysis suggest that trust in fairness has no impact on TV demand. Our scenario analysis further reveals that awareness about a major doping case negatively affects trust in the fair conduct and integrity of athletes. However, we again find no general effect on the demand for sports. Implications Results of our study suggest that athletes can be seen as (dis)trust ambassadors promoting the (un)fairness of the sporting competition to consumers. However, in contrast to popular (political) claims, our results question the trust channel as a driver for spectator sports demand and as a mechanism in the doping-demand relation.

The effect of adaptivity in digital learning technologies. Modelling learning efficiency using data from an educational game

AbstractDuring the last decade, many governments and ed‐tech companies have demonstrated an increased interest in digital personalised learning, which resulted in a variety of often game‐like adaptive learning environments. However, there has been limited attention for the impact of these personalised learning technologies on children's learning efficiency. Does digital personalised learning, like popular claims insist, foster learning in young children? This study attempts to empirically validate the beneficial impact of adaptive learning technology by analysing log‐data from the Number Sense Game (NSG), an educational game that trains early numerical skills. In total, 81 children were randomly assigned to use either an adaptive or a non‐adaptive version of the NSG in six sessions in a three‐week period. Using a longitudinal item response model children's progress within and across sessions was modelled and compared between the two versions of the game. Regardless of the version of the NSG, children demonstrated progress within and across sessions. However, compared to the non‐adaptive NSG, the progress across sessions was stronger in the adaptive NSG. These results provide empirical evidence that adaptive learning environments can improve learning efficiency in young children. Practitioner notesWhat is already known about this topic Adaptive digital technologies are able to address students’ individual needs. Pretest posttest intervention research on the effectiveness of adaptive digital technologies revealed mixed results. What this paper adds Learning effectiveness is different from learning efficiency. Learning efficiency can be operationalised using log‐data to model students’ progress over time. Adaptive digital technologies increased students’ learning efficiency compared to non‐adaptive digital technologies. Implications for practice and/or policy Log‐data can be obtained unintrusively and provides fine‐grained information about students’ learning. Researchers are encouraged to investigate the effects of adaptive digital technologies in terms of learning effectiveness and learning efficiency.

On the Foundations of Dahlhaus’s Foundations

In the foreword to his Grundlagen der Musikgeschichte (1977), translated into English as Foundations of Music History (1983), Carl Dahlhaus names three reasons for writing the book: the lack of theoretical reflection in his own field; the problem of mediation between methodological maxims and their political implications; and the difficulties he encountered while preparing his history of nineteenth-century music. Each of the three reasons can now be understood more precisely and historically contextualized in light of recently uncovered letters and notes. Dahlhaus’s methodological critiques of political music as conceptually distinct from aesthetically autonomous works—contrary to a popular claim by Anne Shreffler (2003)—were directed mainly at the “Western left.” Moreover, in the 1980s this controversy became intertwined with historiographical questions regarding the concept of “event” that was reinforced in publications by the “Gruppe Poetik und Hermeneutik.” A postscript discusses the English translation of the book and the concept of “structural history” in late Dahlhaus.

Shifting attention to accuracy can reduce misinformation online.

In recent years, there has been a great deal of concern about the proliferation of false and misleading news on social media1-4. Academics and practitioners alike have asked why people share such misinformation, and sought solutions to reduce the sharing of misinformation5-7. Here, we attempt to address both of these questions. First, we find that the veracity of headlines has little effect on sharing intentions, despite having a large effect on judgments of accuracy. This dissociation suggests that sharing does not necessarily indicate belief. Nonetheless, most participants say it is important to share only accurate news. To shed light on this apparent contradiction, we carried out four survey experiments and a field experiment on Twitter; the results show that subtly shifting attention to accuracy increases the quality of news that people subsequently share. Together with additional computational analyses, these findings indicate that people often share misinformation because their attention is focused on factors other than accuracy-and therefore they fail to implement a stronglyheld preference for accurate sharing. Our results challenge the popular claim that people value partisanship over accuracy8,9, and provide evidence for scalable attention-based interventions that social media platforms could easily implement to counter misinformation online.

A puzzle about laws and explanation

In this paper, we argue that the popular claim that laws of nature explain their instances (explanatory laws) creates a philosophical puzzle when it is combined with the widely held requirement that explanations need to be underpinned by ‘wordly’ relations (explanatory realism). We argue that a “direct solution” to the puzzle that accounts for both explanatory laws and explanatory realism requires endorsing at least a radical metaphysics. Then, we examine the ramifications of a “skeptical solution”, i.e., dissolving it by giving up at least one of these two claims, and argue that adopting it is more favorable to Humean reductionists than to anti-reductionists about laws of nature.

The case for formal methodology in scientific reform.

Current attempts at methodological reform in sciences come in response to an overall lack of rigor in methodological and scientific practices in experimental sciences. However, most methodological reform attempts suffer from similar mistakes and over-generalizations to the ones they aim to address. We argue that this can be attributed in part to lack of formalism and first principles. Considering the costs of allowing false claims to become canonized, we argue for formal statistical rigor and scientific nuance in methodological reform. To attain this rigor and nuance, we propose a five-step formal approach for solving methodological problems. To illustrate the use and benefits of such formalism, we present a formal statistical analysis of three popular claims in the metascientific literature: (i) that reproducibility is the cornerstone of science; (ii) that data must not be used twice in any analysis; and (iii) that exploratory projects imply poor statistical practice. We show how our formal approach can inform and shape debates about such methodological claims.

The Relationship between Shareholder Return and CEO Pay over a CEO's Full Period of Service

The author reports the findings of his examination of the relationship between CEO pay and performance, as measured by shareholder returns, using measures of compensation and returns that span a CEO's full period of service. Unlike studies that look at annual measures of CEO pay and stock returns—which are distorted by the widespread use of options and the arbitrary effects of when CEOs choose to exercise their options—the author finds a statistically significant connection between total compensation and shareholder return measured over full periods of service for 521 S&P 500 CEOs. Indeed, after one adjusts for differences in the length of a CEO's service, shareholder return is arguably the most important determinant of variation in the amount paid CEOs over their complete tenures.Besides answering the legion of critics of CEO pay, the author's analysis refutes the claim that bull markets are the main force driving executive pay by demonstrating that the increases in career pay attributable to increases in shareholder returns are almost exactly offset by reductions in pay when the Value‐Weighted (S&P 500) Index increases by the same amount. In other words, CEOs’ cumulative career pay is effectively driven by the extent to which their stock returns outperform the broad market. The analysis also casts doubt on the popular claim that the link between CEO pay and corporate size provides incentives to undertake even value‐reducing acquisitions to boost size. As the author's analysis shows, the estimated losses in career CEO pay associated with even small declines in shareholder returns are likely to be offset by the pay increases attributable to size.

Are Events Things of the Past?

AbstractA popular claim in recent philosophy of mind and action is that events only exist once they are over. This has been taken to have the consequence that many temporal phenomena cannot be understood ‘from the inside’, as they are unfolding, purely in terms of events. However, as I argue here, the claim that events exist only when over is incoherent. I consider two ways of understanding the claim and the notion of existence it involves: one that ties existence to the logic of quantification, and another that assimilates the existence of an event to that of a continuant. The first of these, I argue, cannot be the right way to understand the target claim, as there are serious logical obstacles to regarding this notion of existence as temporally variable. The second, on the other hand, leaves it ultimately mysterious what the existence of an event could amount to. I close with the suggestion that the undeniable temporal asymmetries which parties to the debate are interested in are properly understood in perspectival, not ontological, terms.

Effects of immersive storytelling on affective, cognitive, and associative empathy: The mediating role of presence

Popular claims of virtual reality systems serving as ‘empathy machines’ often fail to consider (a) the cognitive mechanisms driving the effects of technological immersion on empathy and (b) the conceptualization of empathy as a multidimensional construct. More, recent research has yielded mixed empirical support. This study investigates how dimensions of psychological presence—perceived self-location, sense of copresence, and judgments of social realism—mediate the effect of immersion on cognitive, affective, and associative empathy. Findings indicate that experiencing a news story via 360° video on a head-mounted display led to stronger self-location and copresence than engaging with the same video via desktop or reading a text version. While only copresence increased cognitive empathy, both self-location and copresence facilitated affective empathy. Whereas self-location and copresence enhanced associative empathy, social realism decreased it. These results highlight the value of a multidimensional conceptualization of empathy in investigating the prosocial potential of immersive media.

Practical Applications of Divergent ESG Ratings

In Divergent ESG Ratings, from the November 2020 issue of The Journal of Portfolio Management, authors Elroy Dimson of the University of Cambridge Judge Business School and Paul Marsh and Mike Staunton of London Business School address inconsistencies in how environmental, social, and governance (ESG) ratings are evaluated by raters and used by asset managers and investors. The authors carried out an extensive review of previous literature on ESG fund and index performance, along with an analysis of variations in ESG ratings given by different rating bodies. Their analysis found that many popular claims that ESG investing outperforms conventional indexes are unfounded. Furthermore, there is no clear agreement among raters on how individual companies score, or on the relative importance of individual factors of ESG ratings. The divergent ESG ratings provide little to no clear direction for asset managers and investors intending to implement ESG investment strategies.
