Indestructibility of Vopenka's Principle

We show that Vopenka's Principle and Vopenka cardinals are indestructible under reverse Easton forcing iterations of increasingly directed-closed partial orders, without the need for any preparatory forcing. As a consequence, we are able to prove the relative consistency of these large cardinal axioms with a variety of statements known to be independent of ZFC, such as the generalised continuum hypothesis, the existence of a definable well-order of the universe, and the existence of morasses at many cardinals.Comment: 15 pages, submitted to Israel Journal of Mathematic

Griaule's Legacy: Rethinking "la parole claire" in Dogon Studies

RÉSUMÉL'héritage de Griaule : repenser la Parole claire dans les études dogon.Comment lire l'œuvre de Griaule et évaluer son héritage ethnographique ? Que peut-on tirer de son projet ethnophilosophique ? Pour répondre à ces questions, je propose une relecture critique de son ethnographie dogon ainsi qu'un nouveau modèle du savoir ésotérique qu'il prétendit révéler. Ma relecture s'appuie sur deux approches méthodologiques qui redéfinissent le projet exégétique en des termes socialement plus dynamiques. La première approche, qui se fonde sur ma recherche sur les Yoruba au Nigeria, s'appuie sur l'hypothèse selon laquelle les niveaux ésotériques des systèmes philosophiques africains sont en réalité indéterminés et instables, et cette capacité à contredire ou bouleverser le savoir officiel ou ésotérique rend le savoir secret opératoire et donc puissant. La seconde approche méthodologique fait passer l'analyse élaborée de la langue et du symbolisme dogon de l'École de Griaule au niveau de l'analyse pragmatique, plaçant les symboles et schémas dominants ainsi que les genres discursifs rituels dans leurs contextes perfomatifs. En nous concentrant sur les actes de langage, les locatifs, le glissement pronominal et les idées qu'ont les Dogon de leur mise en scène linguistique, nous pouvons revenir sur les riches matériaux dogon et en tirer un modèle dynamique de l'action critique comme l'héritage durable de « la parole claire ».ABSTRACTHow do we read Griaule's œuvre, and assess its ethnographic legacy?   What can we gain from his ethnophilosophical project?   To answer these questions, I propose a critical re-reading of his Dogon ethnography and a new model of the esoteric knowledge that he purported to reveal.   My re-reading is based on two methodological moves that recast Griaule's exegetical project in more socially dynamic terms. The first move, based on my Yoruba research in Nigeria, is that esoteric levels of African philosophical systems are actually indeterminate and unstable, and that this capacity to contradict or subvert official or exoteric knowledge renders secret knowledge transformative and thus powerful.   The second methodological move shifts the Griaule school's elaborate analysis of Dogon language and symbolism to the level of pragmatic analysis, locating dominant symbols, schemas and ritual speech-genres in their performative contexts.   Focusing on speech-acts, locatives, and pronominal shifting, as well as on Dogon ideas about linguistic performance, we can return to the rich Dogon material and derive a dynamic model of critical agency as an enduring legacy of "la parole claire"

Nigerian scam e-mails and the charms of capital

So-called '419' or 'advance-fee' e-mail frauds have proved remarkably successful. Global losses to these scams are believed to run to billions of dollars. Although it can be assumed that the promise of personal gain which these e-mails hold out is part of what motivates victims, there is more than greed at issue here. How is it that the seemingly incredible offers given in these unsolicited messages can find an audience willing to treat them as credible? The essay offers a speculative thesis in answer to this question. Firstly, it is argued, these scams are adept at exploiting common presuppositions in British and American culture regarding Africa and the relationships that are assumed to exist between their nations and those in the global south. Secondly, part of the appeal of these e-mails lies in the fact that they appear to reveal the processes by which wealth is created and distributed in the global economy. They thus speak to their readers’ attempts to map or conceptualise the otherwise inscrutable processes of that economy. In the conclusion the essay looks at the contradictions in the official state response to this phenomena

The politics and aesthetics of commemoration: national days in southern Africa

The contributions to the special section in this issue study recent independence celebrations and other national days in South Africa, Namibia, Zimbabwe, Madagascar and the Democratic Republic of Congo. They explore the role of national days in state-making and nation-building, and examine the performativity of nationalism and the role of performances in national festivities. Placing the case studies in a broader, comparative perspective, the introduction first discusses the role of the state in national celebrations, highlighting three themes: firstly, the political power-play and contested politics of memory involved in the creation of a country’s festive calendar; secondly, the relationship between state control of national days and civic or popular participation or contestation; and thirdly, the complex relationship between regional and ethnic loyalties and national identifications. It then turns to the role of performance and aesthetics in the making of nations in general, and in national celebrations in particular. Finally, we look at the different formats and meanings of national days in the region and address the question whether there is anything specific about national days in southern Africa as compared to other parts of the continent or national celebrations world-wide.Web of Scienc

Curious Users of Casual Creators

Casual creators are a type of design tool identified by Compton & Mateas, characterised by an orientation towards enjoyable, intrinsically motivated creative exploration, rather than task-oriented designer productivity. In our experiments holding rapid game jams with Wevva, a casual creator for mobile game design, we have noticed, however, that users seem to vary considerably even within the context of using a casual creator. Some people focus on designing specific games, while others explore the design space extensively, or even focus exclusively on prodding the edges of the design space looking for its possibilities and limits. We hypothesise that the latter group of users is driven primarily by curiosity about a casual creator and its design space. This results in different patterns of behaviour to the former group (of design-oriented users), which may worth characterising and perhaps explicitly designing for

Research Priorities in Pediatric Asthma Morbidity: Addressing the Impacts of Systemic Racism on Children with Asthma in the United States. An Official American Thoracic Society Workshop Report.

Background: In the United States, Black and Latino children with asthma are more likely than White children with asthma to require emergency department visits or hospitalizations because of an asthma exacerbation. Although many cite patient-level socioeconomic status and access to health care as primary drivers of disparities, there is an emerging focus on a major root cause of disparities-systemic racism. Current conceptual models of asthma disparities depict the historical and current effects of systemic racism as the foundation for unequal exposures to social determinants of health, environmental exposures, epigenetic factors, and differential healthcare access and quality. These ultimately lead to biologic changes over the life course resulting in asthma morbidity and mortality. Methods: At the 2022 American Thoracic Society International Conference, a diverse panel of experts was assembled to identify gaps and opportunities to address systemic racism in childhood asthma research. Panelists found that to examine and address the impacts of systemic racism on children with asthma, researchers and medical systems that support biomedical research will need to 1) address the current gaps in our understanding of how to conceptualize and characterize the impacts of systemic racism on child health, 2) design research studies that leverage diverse disciplines and engage the communities affected by systemic racism in identifying and designing studies to evaluate interventions that address the racialized system that contributes to disparities in asthma health outcomes, and 3) address funding mechanisms and institutional research practices that will be needed to promote antiracism practices in research and its dissemination. Results: A thorough literature review and expert opinion discussion demonstrated that there are few studies in childhood asthma that identify systemic racism as a root cause of many of the disparities seen in children with asthma. Community engagement and participation in research studies is essential to design interventions to address the racialized system in which patients and families live. Dissemination and implementation studies with an equity lens will provide the multilevel evaluations required to understand the impacts of interventions to address systemic racism and the downstream impacts. To address the impacts of systemic racism and childhood asthma, there needs to be increased training for research teams, funding for studies addressing research that evaluates the impacts of racism, funding for diverse and multidisciplinary research teams including community members, and institutional and financial support of advocating for policy changes based on study findings. Conclusions: Innovative study design, new tools to identify the impacts of systemic racism, community engagement, and improved infrastructure and funding are all needed to support research that will address impacts of systemic racism on childhood asthma outcomes

Contemporary Africa through the theory of Louis Dumont

Abstract This article responds to a trend in recent anthropological scholarship in Africa that has overemphasized a lack of social organization following the advancement of neoliberal reforms across the continent. Using a theoretical framework informed by the theory of Louis Dumont, I show that social organization remains an important analytical topic in times of crisis, and that this is best apprehended through an analysis of values. The ethnographic focus of this article is Pentecostal Christianity as it is practiced on the Zambian Copperbelt. In this particular African context, Pentecostalism is animated by an overarching value that I call "moving," which is in turn made up to two sub-values: charisma and prosperity. By exploring how Pentecostal believers navigate the hierarchical relationship between these two sub-values, we are given a clear picture of the social world that Pentecostal adherence makes possible

Population genomic data reveal genes related to important traits of quail

Background: Japanese quail (Coturnix japonica), a recently domesticated poultry species, is important not only as an agricultural product, but also as a model bird species for genetic research. However, most of the biological questions concerning genomics, phylogenetics, and genetics of some important economic traits have not been answered. It is thus necessary to complete a high-quality genome sequence as well as a series of comparative genomics, evolution, and functional studies. Results: Here, we present a quail genome assembly spanning 1.04 Gb with 86.63% of sequences anchored to 30 chromosomes (28 autosomes and 2 sex chromosomes Z/W). Our genomic data have resolved the long-term debate of phylogeny among Perdicinae (Japanese quail), Meleagridinae (turkey), and Phasianinae (chicken). Comparative genomics and functional genomic data found that four candidate genes involved in early maturation had experienced positive selection, and one of them encodes follicle stimulating hormone beta (FSHβ), which is correlated with different FSHβ levels in quail and chicken. We re-sequenced 31 quails (10 wild, 11 egg-type, and 10 meat-type) and identified 18 and 26 candidate selective sweep regions in the egg-type and meat-type lines, respectively. That only one of them is shared between egg-type and meat-type lines suggests that they were subject to an independent selection. We also detected a haplotype on chromosome Z, which was closely linked with maroon/yellow plumage in quail using population resequencing and a genome-wide association study. This haplotype block will be useful for quail breeding programs. Conclusions: This study provided a high-quality quail reference genome, identified quail-specific genes, and resolved quail phylogeny. We have identified genes related to quail early maturation and a marker for plumage color, which is significant for quail breeding. These results will facilitate biological discovery in quails and help us elucidate the evolutionary processes within the Phasianidae family

A Questionnaire on Materialisms

Recent philosophical tendencies of “Actor-Network Theory,” “Object-Oriented Ontology,” and “Speculative Realism” have profoundly challenged the centrality of subjectivity in the humanities, and many artists and curators, particularly in the UK, Germany, and the United States, appear deeply influenced by this shift from epistemology to ontology. October editors asked artists, historians, and philosophers invested in these projects—from Graham Harman and Alexander R. Galloway to Armen Avanessian and Patricia Falguières to Ed Atkins and Amie Siegel—to explore what the rewards and risks of assigning agency to objects may be, and how, or if, such new materialisms can be productive for making and thinking about art today
