    When Tom Cassidy and Catherine Rose were purged from the One Big Union (OBU) in October 1923 for their illicit sexual relationship, it unleashed an intense and at times dramatic series of confrontations lasting more than six months in which members said to advocate the ideals of “free love” became the greatest threat to the union's existence. Remarkably, these debates at dozens of union meetings occurred without any public reference to sex. Instead, OBU executive members contained the sexual content of Cassidy's and Rose's affair by posing the question of their relationship in terms of a value judgement about what would hinder the progress of the union. To talk of sex, they argued, would enable a sexual Red Scare at the hands of the bourgeois press. The OBU would be destroyed in the ensuing panic over charges of “free love” and the working-class movement for liberation would be undermined. But underneath their concern to protect the union's reputation lay patriarchal assumptions about heterosexuality, both as sexual practice and family structure, to explain the union's existence, its organizational tactics, and their dream of a better future. Thus, it was not so much that the OBU Executive refused to challenge conservative sexual values to protect the union, but that they promoted these values.En octobre 1923, l'expulsion de Tom Cassidy et de Catherine Rose du syndicat One Big Union (OBU), en raison de leurs relations sexuelles illicites, a déclenché à l'intérieur du syndicat une série de confrontations intenses et parfois orageuses qui a duré plus de six mois pendant lesquels des membres qui défendaient les idéaux de « l'amour libre » sont devenus la pire menace à son existence. Fait étonnant, pendant ces débats survenus lors de douzaines de réunions syndicales, jamais la question des rapports sexuels n'a été publiquement soulevée. Les membres de la direction du OBU ont escamoté l'aspect sexuel de l'affaire Cassidy-Rose en portant le débat à un autre niveau, celui d'un jugement de valeur à propos de ce qui compromettrait les progrès du syndicat. Ils soutenaient qu'en parlant de sexualité, ils prêteraient flanc au scandale dans la presse bourgeoise. La panique suscitée par les allégations « d'amour libre » détruirait l’OBU et le mouvement de libération de la classe ouvrière serait miné. Mais cette préoccupation pour la réputation du syndicat cachait des notions patriarcales à propos de l'hétérosexualité, à la fois pratique sexuelle et structure familiale, qui étaient le fondement même du syndicat, de ses tactiques organisationnelles et de sa quête d'un avenir meilleur. Ainsi, la question n'était pas tant que la direction de l’OBU refusait de contester des valeurs sexuelles traditionnelles afin de protéger le syndicat, mais plutôt qu 'elle préconisait ces valeurs

    A Preliminary Study of Maximum System-Level Crosstalk at High Frequencies for Coupled Transmission Lines

    Simple formulas were derived to quickly estimate maximum crosstalk between wires in a harness at high frequencies, where the length of circuits is comparable with or greater than the wavelength of the signals of interest. Formulas were derived from multi-conductor transmission line theory. When the source and load resistances are either both large or both small compared to the characteristic impedance of the transmission line, maximum coupling is shown to be given by approximately XMAX = Cm / (C22 + Cm). A similar equation was found for the case where the load impedances are matched. Experiments show these equations predict the maximum value of coupling well

    Abstract Background Cellular changes described in human gastroparesis have revealed a role for immune dysregulation, however, a mechanistic understanding of human gastroparesis and the signaling pathways involved are still unclear. Methods Diabetic gastroparetics, diabetic non-gastroparetic controls, idiopathic gastroparetics and non-diabetic non-gastroparetic controls underwent full-thickness gastric body biopsies. Deep RNA sequencing was performed and pathway analysis of differentially expressed transcripts was done using Ingenuity®. A subset of differentially expressed genes in diabetic gastroparesis was validated in a separate cohort using QT-PCR. Results 111 genes were differentially expressed in diabetic gastroparesis and 181 in idiopathic gastroparesis with a log2fold difference of | ≥ 2| and false detection rate (FDR) < 5%. Top canonical pathways in diabetic gastroparesis included genes involved with macrophages, fibroblasts and endothelial cells in rheumatoid arthritis, osteoarthritis pathway and differential regulation of cytokine production in macrophages and T helper cells by IL-17A and IL-17F. Top canonical pathways in idiopathic gastroparesis included genes involved in granulocyte adhesion and diapedesis, agranulocyte adhesion and diapedesis, and role of macrophages, fibroblasts and endothelial cells in rheumatoid arthritis. Sixty-five differentially expressed genes (log2fold difference | ≥ 2|, FDR < 5%) were common in both diabetic and idiopathic gastroparesis with genes in the top 5 canonical pathways associated with immune signaling. 4/5 highly differentially expressed genes (SGK1, APOLD1, CXCR4, CXCL2, and FOS) in diabetic gastroparesis were validated in a separate cohort of patients using RT-PCR. Immune profile analysis revealed that genes associated with M1 (pro inflammatory) macrophages were enriched in tissues from idiopathic gastroparesis tissues compared to controls (p < 0.05). Conclusions Diabetic and idiopathic gastroparesis have both unique and overlapping transcriptomic signatures. Innate immune signaling likely plays a central role in pathogenesis of human gastroparesis.https://deepblue.lib.umich.edu/bitstream/2027.42/145193/1/12920_2018_Article_379.pd

    Otitis media in young Aboriginal children from remote communities in Northern and Central Australia: a cross-sectional survey

    Get PDF
    BACKGROUND: Middle ear disease (otitis media) is common and frequently severe in Australian Aboriginal children. There have not been any recent large-scale surveys using clear definitions and a standardised middle ear assessment. The aim of the study was to determine the prevalence of middle ear disease (otitis media) in a high-risk population of young Aboriginal children from remote communities in Northern and Central Australia. METHODS: 709 Aboriginal children aged 6–30 months living in 29 communities from 4 health regions participated in the study between May and November 2001. Otitis media (OM) and perforation of the tympanic membrane (TM) were diagnosed by tympanometry, pneumatic otoscopy, and video-otoscopy. We used otoscopic criteria (bulging TM or recent perforation) to diagnose acute otitis media. RESULTS: 914 children were eligible to participate in the study and 709 were assessed (78%). Otitis media affected nearly all children (91%, 95%CI 88, 94). Overall prevalence estimates adjusted for clustering by community were: 10% (95%CI 8, 12) for unilateral otitis media with effusion (OME); 31% (95%CI 27, 34) for bilateral OME; 26% (95%CI 23, 30) for acute otitis media without perforation (AOM/woP); 7% (95%CI 4, 9) for AOM with perforation (AOM/wiP); 2% (95%CI 1, 3) for dry perforation; and 15% (95%CI 11, 19) for chronic suppurative otitis media (CSOM). The perforation prevalence ranged from 0–60% between communities and from 19–33% between regions. Perforations of the tympanic membrane affected 40% of children in their first 18 months of life. These were not always persistent. CONCLUSION: Overall, 1 in every 2 children examined had otoscopic signs consistent with suppurative ear disease and 1 in 4 children had a perforated tympanic membrane. Some of the children with intact tympanic membranes had experienced a perforation that healed before the survey. In this high-risk population, high rates of tympanic perforation were associated with high rates of bulging of the tympanic membrane

    ANSI/NISO Z39.99-2017 ResourceSync Framework Specification

    This ResourceSync specification describes a synchronization framework for the web consisting of various capabilities that allow third-party systems to remain synchronized with a server’s evolving resources. The capabilities may be combined in a modular manner to meet local or community requirements. This specification also describes how a server should advertise the synchronization capabilities it supports and how third-party systems may discover this information. The specification repurposes the document formats defined by the Sitemap protocol and introduces extensions for them

    The Effectiveness of Sedentary Behaviour Interventions for Reducing Body Mass Index in Children and Adolescents: Systematic Review and Meta-analysis

    Get PDF
    Intervention studies have been undertaken to reduce sedentary behaviour (SB) and thereby potentially ameliorate unhealthy weight gain in children and adolescents. We synthesised evidence and quantified the effects of SB interventions (single or multiple components) on body mass index (BMI) or BMI z-score in this population. Publications up to March 2015 were located through electronic searches. Inclusion criteria were interventions targeting SB in children that had a control group and objective measures of weight and height. Mean change in BMI or BMI z-score from baseline to post-intervention were quantified for intervention and control groups and meta-analyzed using a random effects model. The pooled mean reduction in BMI and BMI z-score was significant but very small (standardized mean difference = -0.060, 95% confidence interval: -0.098 to -0.022). However, the pooled estimate was substantially greater for an overweight or obese population (standardized mean difference = -0.255, 95% confidence interval: -0.400 to -0.109). Multicomponent interventions (SB and other behaviours) delivered to children from 5 to 12 years old in a non-educational setting appear to favour BMI reduction. In summary, SB interventions are associated with very small improvement in BMI in mixed-weight populations. However, SB interventions should be part of multicomponent interventions for treating obese children

    Beak and feather disease virus in wild and captive parrots: an analysis of geographic and taxonomic distribution and methodological trends

    Get PDF
    Psittacine beak and feather disease (PBFD) has emerged in recent years as a major threat to wild parrot populations and is an increasing concern to aviculturists and managers of captive populations. Pathological and serological tests for screening for the presence of beak and feather disease virus (BFDV) are a critical component of efforts to manage the disease and of epidemiological studies. Since the disease was first reported in the mid-1970s, screening for BFDV has been conducted in numerous wild and captive populations. However, at present, there is no current and readily accessible synthesis of screening efforts and their results. Here, we consolidate information collected from 83 PBFD- and BFDV-based publications on the primary screening methods being used and identify important knowledge gaps regarding potential global disease hotspots. We present trends in research intensity in this field and critically discuss advances in screening techniques and their applications to both aviculture and to the management of threatened wild populations. Finally, we provide an overview of estimates of BFDV prevalence in captive and wild flocks alongside a complete list of all psittacine species in which the virus has been confirmed. Our evaluation highlights the need for standardised diagnostic tests and more emphasis on studies of wild populations, particularly in view of the intrinsic connection between global trade in companion birds and the spread of novel BFDV strains into wild populations. Increased emphasis should be placed on the screening of captive and wild parrot populations within their countries of origin across the Americas, Africa and Asia
