Rethinking and remaking “the social”:co-production, critical pedagogy, and mental health among university students in the USA

This paper presents findings from a qualitative study exploring how students at a university in the southern USA conceptualize, theorize, and attempt to influence the role ‘social factors’ play in mental illness and well-being. Drawing on models of research co-production and principles of critical pedagogy, a group of 10 university students (‘student researchers’) worked with a faculty member to develop and conduct the study. The results highlight three ways in which the student interviewees (‘student interlocutors’) theorize ‘the social’. The first two – (1) via the ‘social determinants of health’ and (2) by means of theories on ‘neoliberal subjectivity’ – provide a powerful frame for interrogating hierarchical systems of power. However, because neither of these corresponds to our interest in producing knowledge for social change, we used prefigurative and speculative approaches to explore a third notion of the social, that of (3) ‘world-making practices’. We conclude by reflecting on the relevance of this project for educators, learners, and researchers seeking to deepen knowledge and theories of the social in mental health. We argue that co-produced research that draws from principles of critical pedagogy can enhance interdisciplinary collaboration and lead to more nuanced, transformative, and innovative analyses

Host Identity and Geographic Location Significantly Affect Gastrointestinal Microbial Richness and Diversity in Western Lowland Gorillas (Gorilla gorilla gorilla) under Human Care

The last few decades have seen an outpouring of gastrointestinal (GI) microbiome studies across diverse host species. Studies have ranged from assessments of GI microbial richness and diversity to classification of novel microbial lineages. Assessments of the “normal” state of the GI microbiome composition across multiple host species has gained increasing importance for distinguishing healthy versus diseased states. This study aimed to determine baselines and trends over time to establish “typical” patterns of GI microbial richness and diversity, as well as interindividual variation, in three populations of western lowland gorillas (Gorilla gorilla gorilla) under human care at three zoological institutions in North America. Fecal samples were collected from 19 western lowland gorillas every two weeks for seven months (n = 248). Host identity and host institution significantly affected GI microbiome community composition (p \u3c 0.05), although host identity had the most consistent and significant effect on richness (p = 0.03) and Shannon diversity (p = 0.004) across institutions. Significant changes in microbial abundance over time were observed only at Denver Zoo (p\u3c 0.05). Our results suggest that individuality contributes to most of the observed GI microbiome variation in the study populations. Our results also showed no significant changes in any individual’s microbial richness or Shannon diversity during the 7-month study period. While some microbial taxa (Prevotella, Prevotellaceae and Ruminococcaceae) were detected in all gorillas at varying levels, determining individual baselines for microbial composition comparisons may be the most useful diagnostic tool for optimizing non-human primate health under human care

A microfungus from Costa Rica: Ticosynnema gen. nov.

Ticosynnema carranzae gen. & sp. nov., a new microfungus collected on the twig of an unidentified plant, is described and illustrated. It is distinguished by synnematous determinate conidiomata, monoblastic integrated determinate conidiogenous cells, and solitary, 3–4-septate, oblong, cylindrical to vermiform, brown conidia that secede rhexolytically.UCR::Vicerrectoría de Docencia::Ciencias Agroalimentarias::Facultad de Ciencias Agroalimentarias::Escuela de AgronomíaUCR::Vicerrectoría de Investigación::Unidades de Investigación::Ciencias Agroalimentarias::Centro de Investigación en Protección de Cultivos (CIPROC)UCR::Vicerrectoría de Docencia::Ciencias Básicas::Facultad de Ciencias::Escuela de Biologí

The Amsterdam Declaration on Fungal Nomenclature

The Amsterdam Declaration on Fungal Nomenclature was agreed at an international symposium convened in Amsterdam on 19–20 April 2011 under the auspices of the International Commission on the Taxonomy of Fungi (ICTF). The purpose of the symposium was to address the issue of whether or how the current system of naming pleomorphic fungi should be maintained or changed now that molecular data are routinely available. The issue is urgent as mycologists currently follow different practices, and no consensus was achieved by a Special Committee appointed in 2005 by the International Botanical Congress to advise on the problem. The Declaration recognizes the need for an orderly transitition to a single-name nomenclatural system for all fungi, and to provide mechanisms to protect names that otherwise then become endangered. That is, meaning that priority should be given to the first described name, except where that is a younger name in general use when the first author to select a name of a pleomorphic monophyletic genus is to be followed, and suggests controversial cases are referred to a body, such as the ICTF, which will report to the Committee for Fungi. If appropriate, the ICTF could be mandated to promote the implementation of the Declaration. In addition, but not forming part of the Declaration, are reports of discussions held during the symposium on the governance of the nomenclature of fungi, and the naming of fungi known only from an environmental nucleic acid sequence in particular. Possible amendments to the Draft BioCode (2011) to allow for the needs of mycologists are suggested for further consideration, and a possible example of how a fungus only known from the environment might be described is presented

A ring-like accretion structure in M87 connecting its black hole and jet

The nearby radio galaxy M87 is a prime target for studying black hole accretion and jet formation1,2. Event Horizon Telescope observations of M87 in 2017, at a wavelength of 1.3 mm, revealed a ring-like structure, which was interpreted as gravitationally lensed emission around a central black hole3. Here we report images of M87 obtained in 2018, at a wavelength of 3.5 mm, showing that the compact radio core is spatially resolved. High-resolution imaging shows a ring-like structure of [Formula: see text] Schwarzschild radii in diameter, approximately 50% larger than that seen at 1.3 mm. The outer edge at 3.5 mm is also larger than that at 1.3 mm. This larger and thicker ring indicates a substantial contribution from the accretion flow with absorption effects, in addition\ua0to the gravitationally lensed ring-like emission. The images show that the edge-brightened jet connects to the accretion flow of the black hole. Close to the black hole, the emission profile of the jet-launching region is wider than the expected profile of a black-hole-driven jet, suggesting the possible presence of a wind associated with the accretion flow

A ring-like accretion structure in M87 connecting its black hole and jet

The nearby radio galaxy M87 is a prime target for studying black hole accretion and jet formation^{1,2}. Event Horizon Telescope observations of M87 in 2017, at a wavelength of 1.3 mm, revealed a ring-like structure, which was interpreted as gravitationally lensed emission around a central black hole^3. Here we report images of M87 obtained in 2018, at a wavelength of 3.5 mm, showing that the compact radio core is spatially resolved. High-resolution imaging shows a ring-like structure of 8.4_{-1.1}^{+0.5} Schwarzschild radii in diameter, approximately 50% larger than that seen at 1.3 mm. The outer edge at 3.5 mm is also larger than that at 1.3 mm. This larger and thicker ring indicates a substantial contribution from the accretion flow with absorption effects in addition to the gravitationally lensed ring-like emission. The images show that the edge-brightened jet connects to the accretion flow of the black hole. Close to the black hole, the emission profile of the jet-launching region is wider than the expected profile of a black-hole-driven jet, suggesting the possible presence of a wind associated with the accretion flow.Comment: 50 pages, 18 figures, 3 tables, author's version of the paper published in Natur

African Migration, Global Inequalities, and Human Rights : Connecting the Dots

Migration from and within Africa, just like migration elsewhere in the world, often generates anti-immigrant sentiment and ignites heated public debate about the migration policies of the destination countries. These countries include South Africa as well as others outside the continent. The countries of origin are also keen to minimize losses through “brain drain” and to capture resources such as remittances. Increasingly, international organizations and human rights advocates have stressed the need to protect the interests of migrants themselves. However, while the UNDP’s 2009 Human Development Report talks of “win-win-win” solutions, in practice it is the perceived interests of destination countries that enjoy the greatest attention, while the rights of migrants themselves are afforded the least. Yet migration is not just an issue in itself: it also points to structural inequalities between countries and regions. Managing migration and protecting migrants is too limited an agenda. Activists and policymakers must also address these inequalities directly to ensure that people can pursue their fundamental human rights whether they move or stay. It is not enough to measure development only in terms of progress at the national level: development must also be measured in terms of reductions in the gross levels of inequality that now determine differential rights on the basis of accident of birth

WATER SYMBOLISM IN THE RGVEDA

The Rgveda is one of the most important sacred scriptures in the history of religions. Although the language and meaning of many of the Vedic hymns have become obscured through the ages, these hynms are a major foundation of the Indo-European religious tradition. Part One of this study looks at the various roles of water in the Rgveda. Water was particularly important in the Vedic world. It was seen as the raw material in the creation of the cosmos. The account of the release by Indra of the waters which were captured by the demon Vrtra is one of the most important myths in the Rgveda. The Rivers of the Panjab were the primary geographic feature of the Vedic world and gave the Aryans a protective boundary from their enemies. Rain was a major factor in determining the quality of their lives. The Waters (Apah) and several rivers were personified as goddesses. In(\u27 ) particular, the Sarasvat(\u27)i River was personified as best of rivers, best of mothers, and best of goddesses. Analysis is also given of the lesser aquatic deities in the Rgveda, such as Trita Aptya, Apam Napat, and Sarasvan, and of the(\u27 ) relationships of the major Vedic deities to water. The importance of the role of water in the Soma ritual, a cornerstone of the Vedic religion, is discussed. In addition, three specific Vedic hymns (7, 47; 7, 49; and 6, 61) are looked at in detail to see how water deities are portrayed in the Rgveda. Part Two of this study deals with water as symbolic, as pointing toward higher realities which human beings can experience. Suggestions are made for organizing the vast array of details delineated from the Rgveda in the first part of this study. A taxonomy is presented for the various aspects of Vedic water symbolism based on four symbolic chains or strands: those of fluidity, creation, fertility, and purification. A brief summary is given of how these four chains are germane to water symbolism in other religious traditions. There is also a discussion of the unique elements of Vedic water symbolism, in particular the postitive, beneficient quality of water symbols in the Rgveda. Primary focus in this regard is again put on the figure of Sarasvat(\u27)i. The experience of water is a primal encounter of human beings with the natural world. However, it is appreciated less and less by people generally and studied insufficiently by investigators in the field of myth and symbol. Although there has been a large amount of scholarly work done on the Rgveda in the last century, very little of it has dealt with the role of water. It is hoped that this study will shed new light on the diverse area of Vedic symbolism and mythology in general and especially on the importance of its water symbolism
