AbstractAssessments of visceral adipose tissue (VAT) are critical in preventing metabolic disorders; however, there are limited measurement methods that are accurate and accessible for VAT. The purpose of this cross-sectional study was to evaluate the association between VAT estimates from consumer-grade devices and traditional anthropometrics and VAT and subcutaneous adipose tissue (SAT) from dual-energy X-ray absorptiometry (DXA). Data were collected from 182 participants (female = 114; White = 127; Black/African-American (BAA) = 48) which included anthropometrics and indices of VAT produced by near-infrared reactance spectroscopy (NIRS), visual body composition (VBC) and multifrequency BIA (MFBIA). VAT and SAT were collected using DXA. Bivariate and partial correlations were calculated between DXAVAT and DXASAT and other VAT estimates. All VAT indices had positive moderate–strong correlations with VAT (all P < 0·001) and SAT (all P < 0·001). Only waist:hip (r = 0·69), VATVBC (r = 0·84), and VATMFBIA (r = 0·86) had stronger associations with VAT than SAT (P < 0·001). Partial associations between VATVBC and VATMFBIA were only stronger for VAT than SAT in White participants (r = 0·67, P < 0·001) but not female, male, or BAA participants individually. Partial correlations for waist:hip were stronger for VAT than SAT, but only for male (r = 0·40, P < 0·010) or White participants (r = 0·48, P < 0·001). NIRS was amongst the weakest predictors of VAT which was highest in male participants (r = 0·39, P < 0·010) but non-existent in BAA participants (r = –0·02, P > 0·050) after adjusting for SAT. Both anthropometric and consumer-grade VAT indices are consistently better predictors of SAT than VAT. These data highlight the need for a standardised, but convenient, VAT estimation protocol that can account for the relationship between SAT and VAT that differs by sex/race.
Effects of diets containing proteins from fish muscles or fish by-products on the circulating cholesterol concentration in rodents: a systematic review and meta-analysis
Authors: O’Keeffe Maria , Gudbrandsen Oddrun Anita 
Published: October 2022

AbstractA high circulating cholesterol concentration is considered an important risk factor for the development of CVD. Since lean fish intake and fish protein supplementation have been associated with lower cholesterol concentration in some but not all clinical studies, the main aim of this study was to investigate the effect of diets containing proteins from fish muscles and fish by-products on the serum/plasma total cholesterol (TC) concentration in rodents. A systematic literature search was performed using the databases PubMed, Web of Science and Embase, structured around the population (rodents), intervention (type of fish and fraction, protein dose and duration), comparator (casein) and the primary outcome (circulating TC). Articles were assessed for risk of bias using the SYRCLE’s tool. A meta-analysis was conducted in Review Manager v. 5·4·1 (the Cochrane Collaboration) to determine the effectiveness of proteins from fish on the circulating TC concentration. Thirty-nine articles were included in the systematic review and meta-analysis, with data from 935 rodents. The risk of bias is unclear since few of the entries in the SYRCLE’s tool were addressed. Consumption of proteins from fish resulted in a significantly lower circulating TC concentration when compared with control groups (mean difference −0·24 mmol/l, 95 % CI − 0·34, −0·15, P < 0·00001), with high statistical heterogeneity (I2 = 71 %). To conclude, proteins from fish muscles and by-products show promise as a functional dietary ingredient or supplement by preventing high cholesterol concentration in rodents, thus reducing one of the most important risk factors for developing CVD.
Do Anti-immigration Voters Care More? Documenting the Issue Importance Asymmetry of Immigration Attitudes
Authors: Kustov Alexander 
Published: October 2022

AbstractWhy do politicians and policymakers not prioritize pro-immigration reforms, even when public opinion on the issue is positive? This research note examines one previously overlooked explanation related to the systematically greater importance of immigration as a political issue among those who oppose it relative to those who support it. To provide a comprehensive empirical assessment of how personal immigration issue importance is related to policy preferences, I use the best available cross-national and longitudinal surveys from multiple immigrant-receiving contexts. I find that compared to pro-immigration voters, anti-immigration voters feel stronger about the issue and are more likely to consider it as both personally and nationally important. This finding holds across virtually all observed countries, years, and alternative survey measures of immigration preferences and their importance. Overall, these results suggest that public attitudes toward immigration exhibit a substantial issue importance asymmetry that systematically advantages anti-immigration causes when the issue is more contextually salient.
Using General Messages to Persuade on a Politicized Scientific Issue

Published: October 2022

AbstractPolitics and science have become increasingly intertwined. Salient scientific issues, such as climate change, evolution, and stem-cell research, become politicized, pitting partisans against one another. This creates a challenge of how to effectively communicate on such issues. Recent work emphasizes the need for tailored messages to specific groups. Here, we focus on whether generalized messages also can matter. We do so in the context of a highly polarized issue: extreme COVID-19 vaccine resistance. The results show that science-based, moral frame, and social norm messages move behavioral intentions, and do so by the same amount across the population (that is, homogeneous effects). Counter to common portrayals, the politicization of science does not preclude using broad messages that resonate with the entire population.
No Taxation without Efficiency? Elite Perceptions of Redistribution and Progressivity in Chile
Authors: Atria Jorge 
Published: October 2022

AbstractEven though a vast literature has addressed perceptions and beliefs on taxes, progressivity and redistribution, few studies have specifically studied the perceptions of economic elites in this regard. This group is relevant for its affluence and influence, and therefore elites’ ideas and preferences have a major impact on tax-policy configuration. This study analyses the perceptions of the economic elite on redistribution and progressivity in Chile. Based on in-depth interviews and historical documents, such notions are examined by mixing concrete evaluations of income tax and value-added tax (VAT) and more general attitudes towards the role of the tax system in economic development. Results show that redistribution is negatively evaluated, which coexists with a strong willingness to contribute to poverty relief through social initiatives outside the state. Additionally, progressivity is sidelined while highlighting growth, tax neutrality, and incentives to entrepreneurship as the main priorities of tax design. The historical analysis shows that although the Chilean tax regime has always been based on indirect taxes and levies on natural resources, neoliberal reforms and ideological renovation during the Pinochet dictatorship narrowed the general framework of tax ideas among business and political sectors and reversed progressive advances in inequality reduction and direct taxation that had been made during the previous decades.
Studies of Social Revolution: Origins in Mexico, Bolivia, and Cuba
Authors: Blasier Cole 
Published: October 2022

War and revolution are the cataclysmic events of our age which affect man and society more profoundly than any other human phenomenon. In Russia and China war brought revolution. Today, in an age of competitive ideologies and competitive nuclear armament, men fear that revolution will lead to war.The global conflicts that have wracked Eurasia in this century have not touched Latin America directly. The only international conflict of roughly comparable intensity was the Chaco War (1932–1936) in which hostilities were confined to two small powers, Bolivia and Paraguay. Bolivia's defeat was part of a train of events that lead directly to the Revolution of 1952.
Latin American Squatter Settlements: A Problem and a Solution
Authors: Mangin William 
Published: October 2022

Squatter settlements have formed around large cities throughout the world, mushrooming particularly since the end of World War II. In an excellent preview to a forthcoming book, Turner (1966) has discussed some common features among squatter settlements in Latin America, Asia, Africa, and Europe. Morse (1965a) has also referred to squatter communities and to general characteristics of Latin American urbanization in an article in this journal. Without repeating the work of Turner and Morse I would like to present a preliminary survey of Latin American squatter settlements with a model of their formation, growth, and social development that contradicts many views held by planners, politicians, newspapermen, and much of the general population, including many residents of the settlements themselves.Several writers have referred to various local names given to squatter communities:colonies proletariasin Mexico,barriadas brujasin Panama, ranchos in Venezuela, barriadas in Peru, callampas in Chile, cantegriles in Uruguay, favelas in Brazil, and, in other places, marginal areas, clandestine urbanizations, barrios of invasion, parachutists, phantom towns, etc. There are no general works on the subject, but some good descriptions of local conditions do exist. The major sources used are listed by country in note 2. Not many sources are available and, unfortunately, several appear only in mimeographed form. The reports point out that squatter populations consist mainly of low income families but all of the authors distinguish between squatter settlements and other types of lower class housing in tenements, alleys (callejones), shack yards tcoralones, jacales), and rented slum buildings. They agree, sometimes to their own surprise, that it is difficult to describe squatter settlements as slums. The differentiation of squatter settlements from inner-city slums is, in fact, one of the first breaks from the widely shared mythology about them. (See, for example, Patch, 1961; Mangin, 1965.) The purpose in noting this mythology is not merely to set up a straw man for the paper. A review of the “Chaos, Crisis, Revolution and Wither Now Latin America” literature, or, of most governmental, United Nations, or AID reports, or, of most newspapers and magazines in Latin America will show that it is the predominant position on squatter settlements.
Women in Latin America: The State of Research, 1975
Authors: Knaster Meri 
Published: October 2022

Several years ago a single voice, representing the frustration of many of us trying to carry out research on women in Latin America, decried the “lack of core bibliography, methodological apparati, or thematic models” (item 182:125) as major problems besetting the study of women in Latin America. As of 1975, these research hurdles had not been completely overcome, but certainly steps have been and continue to be taken.An annotated bibliography on women in Spanish America will soon be published and other bibliographic guides of a more limited scope have been or are in the process of being compiled. Both in North America and Latin America, conferences, seminars, and workshops have been held to discuss methodological problems as well as recent research efforts. Associations, committees, coalitions, and centers have organized to promote the cause, lend support, gather and distribute information, and generally represent a growing concern with women's issues.
Morphometric and molecular characterization of an unpigmented haemosporidian parasite in the Neotropical turnip-tailed gecko (Thecadactylus rapicauda)

AbstractMorphological traits from blood stages have been the gold standard for determining haemosporidian parasite species. However, the status of some taxa and the value of such traits in parasites from reptiles remain contentious. The scarce sampling of these species worsens the situation, and several taxa lack molecular data. A survey was performed in the Magdalena Department in Colombia, where 16 species of reptiles were captured. A peculiar haemosporidian parasite was found in the Turnip-tailed gecko Thecadactylus rapicauda. This haemosporidian does not show malarial pigment in blood stages under light microscopy; thus, it fits the Garnia genus's characters belonging to the Garniidae. However, the phylogenetic analyses using a partial sequence of cytochrome b and the mitochondrial DNA placed it within the Plasmodium clade. Our findings suggest that many putative Garnia species belong to the genus Plasmodium, like the one reported here. This study either shows that visible malarial pigment in blood stages is not a diagnostic trait of the genus Plasmodium or malarial pigment might be present in an undetectable form under a light microscope. In any case, the current taxonomy of haemosporidian parasites in reptiles requires revision. This study highlights the importance of using molecular and morphological traits to address taxonomic questions at the species and genus levels in haemosporidian parasites from reptiles.
Specifying the psychosocial pathways whereby child and adolescent adversity shape adult health outcomes
Authors: Lei Man-Kit , Berg Mark T. , Simons Ronald L. , Beach Steven R. H. 
Published: October 2022

AbstractBackgroundSocial scientists generally agree that health disparities are produced, at least in part, by adverse social experiences, especially during childhood and adolescence. Building on this research, we use an innovative method to measure early adversity while drawing upon a biopsychosocial perspective on health to formulate a model that specifies indirect pathways whereby childhood and adolescent adversity become biologically embedded and influence adult health.MethodUsing nearly 20 years of longitudinal data from 382 Black Americans, we use repeated-measures latent class analysis (RMLCA) to construct measures of childhood/adolescent adversities and their trajectories. Then, we employ structural equation modeling to examine the direct and indirect effects of childhood/adolescent adversity on health outcomes in adulthood through psychosocial maladjustment.ResultsRMLCA identified two classes for each component of childhood/adolescent adversity across the ages of 10 to 18, suggesting that childhood/adolescent social adversities exhibit a prolonged heterogeneous developmental trajectory. The models controlled for early and adult mental health, sociodemographic and health-related covariates. Psychosocial maladjustment, measured by low self-esteem, depressive and anxiety symptoms, and lack of self-control, mediated the relationship between childhood/adolescent adversity, especially parental hostility, racial discrimination, and socioeconomic class, and both self-reported illness and blood-based accelerated biological aging (with proportion mediation ranging from 8.22% to 79.03%).ConclusionThe results support a biopsychosocial model of health and provide further evidence that, among Black Americans, early life social environmental experiences, especially parenting, financial stress, and racial discrimination, are associated with adult health profiles, and furthermore, psychosocial mechanisms mediate this association.
Disruption from above, the middle and below: Three terrains of governance
Authors: Chua Charmaine 
Published: October 2022

AbstractThe term disruption has become a buzzword for our times, although there is little clarity over what the term means, how it is deployed, and towards what ends. In order to understand the analytical and political stakes that are embedded in the deployment of ‘disruption’ as a rationale for various sources of upheaval, in this article I argue that these three terrains of disruption should be understood as theories of governance, and term them ‘disruption from above’, ‘disruption from the middle’, and ‘disruption from below’. Each terrain of disruption embodies different ethoses, actors, and goals: the first connoting elite-driven creative destruction and innovation; the second obfuscating the capitalist imperative that produces world-systemic upheavals; and the third seeking to expose the structures of violence and inequality built into such practices. I illustrate these three terrains through a structural account that traces the popularity of the disruption discourse from its origins to its material application; analyse an illustrative example of the assetisation of infrastructure and how it bureaucratises governance and shifts relations of power; and conclude by examining infrastructural forms of protest against such forms. I argue that the confusion over what disruption means, who exercises it, and upon whom is not a coincidence: rather, disruption's polysemy is structurally produced as a way to disguise ongoing capitalist crisis as a technical problem that market innovations can solve.
Effect of water stress on weed germination, growth characteristics, and seed production: a global meta-analysis

Published: October 2022

AbstractWeeds compete with crops for soil moisture, along with other resources, which can impact the germination, growth, and seed production of weeds; however, this impact has not been systematically recorded and synthesized across diverse studies. To address this knowledge gap, a global meta-analysis was conducted using 1,196 paired observations from 86 published articles assessing the effect of water stress on weed germination, growth characteristics, and seed production. These studies were conducted and published during 1970 through 2020 across four continents (Asia, Australia, Europe, and North America). Imposed water stress was expressed as solution osmotic potential (ψsolution), soil water potential (ψsoil), or soil moisture as percent field capacity. Meta-analysis revealed that water stress inhibits weed germination, growth, and seed production, and the quantitative response intensified with increasing water stress. A ψsolutiongreater than −0.8 MPa completely inhibits germination of both grass and broadleaf weeds. A ψsolutionfrom −0.09 to −0.32 MPa reduces weed germination by 50% compared with the unstressed condition. Moderate soil water stress, equivalent to 30% to 60% field capacity, inhibits growth characteristics (branches or tillers per plant, leaf area, leaves per plant, plant height, root, and shoot biomass) by 33% and weed seed production by 50%. Severe soil water stress, below 30% field capacity, inhibits weed growth by 51% and seed production by 88%. Although water stress inhibits weed growth, it does not entirely suppress the ability to germinate, grow, and produce seeds, resulting in weed seedbank accumulation. This creates management challenges for producers, because weed seeds can survive in the soil for many years, depending on weed species and environmental conditions. Quantitative information compiled in this meta-analysis can be instrumental to model the weeds’ multidimensional responses to water stress and designing integrated weed management strategies for reducing the weed seedbank.
In-field assessment of EPSPS amplification on fitness cost in mixed glyphosate-resistant and glyphosate-sensitive populations of Palmer amaranth (Amaranthus palmeri)

Published: October 2022

AbstractComparing fitness of herbicide-resistant and herbicide-susceptible weed biotypes is important for managing herbicide resistance. Previous research suggests there is little to no fitness penalty from amplification of the 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) gene (a mechanism of glyphosate resistance) in Palmer amaranth (Amaranthus palmeri S. Watson) in controlled studies in the greenhouse or growth chamber. A field study was conducted in North Carolina at three locations naturally infested with A. palmeri to determine vegetative, reproductive, and germination fitness of plants with and without EPSPS amplification grown season-long with cotton (Gossypium hirsutum L.). Seed number was not correlated with EPSPS copy number. However, when plants were binned into two groups, those having an EPSPS copy number ≥2 (relative to reference genes) and those having an EPSPS copy number <2, plant fresh weight and seed number were 1.4 and 1.6 times greater, respectively, for plants with fewer than 2 EPSPS copies. Amaranthus palmeri height and seed germination, and yield of cotton, did not differ when comparing the two binned groups. These data suggest that A. palmeri plants with EPSPS amplification are relatively less fit in the absence of glyphosate, but this reduced fitness does not translate into differences in interference with cotton.
Machine Learning‐Based Detection of Weather Fronts and Associated Extreme Precipitation in Historical and Future Climates

Published: October 2022

AbstractExtreme precipitation events, including those associated with weather fronts, have wide‐ranging impacts across the world. Here we use a deep learning algorithm to identify weather fronts in high resolution Community Earth System Model (CESM) simulations over the contiguous United States (CONUS), and evaluate the results using observational and reanalysis products. We further compare results between CESM simulations using present‐day and future climate forcing, to study how these features might change with climate change. We find that detected front frequencies in CESM have seasonally varying spatial patterns and responses to climate change and are found to be associated with modeled changes in large scale circulation such as the jet stream. We also associate the detected fronts with precipitation and find that total and extreme frontal precipitation mostly decreases with climate change, with some seasonal and regional differences. Decreases in Northern Hemisphere summer frontal precipitation are largely driven by changes in the frequency of different front types, especially cold and stationary fronts. On the other hand, Northern Hemisphere winter exhibits some regional increases in frontal precipitation that are largely driven by changes in frontal precipitation intensity. While CONUS mean and extreme precipitation generally increase during all seasons in these climate change simulations, the likelihood of frontal extreme precipitation decreases, demonstrating that extreme precipitation has seasonally varying sources and mechanisms that will continue to evolve with climate change.
