    The status of women: Conceptual and methodological issues in demographic studies

    Full text link
    This paper explores several conceptual problems in social demographic studies of the status of women, including failure to recognize the multidimensionality of women's status and its variation across social “locations,” the confounding of gender and class stratification systems, and the confounding of access to resources with their control. Also discussed are some generic problems in the measurement of female status, such as the sensitivity of particular indicators to social context, and the need to select consistent comparisons when judging the extent of gender inequality.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/45651/1/11206_2005_Article_BF01115740.pd

    A deletion in GDF7 is associated with a heritable forebrain commissural malformation concurrent with ventriculomegaly and interhemispheric cysts in cats

    Publisher Copyright: © 2020 by the authors.An inherited neurologic syndrome in a family of mixed-breed Oriental cats has been characterized as forebrain commissural malformation, concurrent with ventriculomegaly and interhemispheric cysts. However, the genetic basis for this autosomal recessive syndrome in cats is unknown. Forty-three cats were genotyped on the Illumina Infinium Feline 63K iSelect DNA Array and used for analyses. Genome-wide association studies, including a sib-transmission disequilibrium test and a case-control association analysis, and homozygosity mapping, identified a critical region on cat chromosome A3. Short-read whole genome sequencing was completed for a cat trio segregating with the syndrome. A homozygous 7 bp deletion in growth differentiation factor 7 (GDF7) (c.221_227delGCCGCGC [p.Arg74Profs]) was identified in affected cats, by comparison to the 99 Lives Cat variant dataset, validated using Sanger sequencing and genotyped by fragment analyses. This variant was not identified in 192 unaffected cats in the 99 Lives dataset. The variant segregated concordantly in an extended pedigree. In mice, GDF7 mRNA is expressed within the roof plate when commissural axons initiate ventrally-directed growth. This finding emphasized the importance of GDF7 in the neurodevelopmental process in the mammalian brain. A genetic test can be developed for use by cat breeders to eradicate this variant.Peer reviewe

    Werewolf, there wolf : Variants in hairless associated with hypotrichia and roaning in the lykoi cat breed

Licensee MDPI, Basel, Switzerland.A variety of cat breeds have been developed via novelty selection on aesthetic, dermatological traits, such as coat colors and fur types. A recently developed breed, the lykoi (a.k.a. werewolf cat), was bred from cats with a sparse hair coat with roaning, implying full color and all white hairs. The lykoi phenotype is a form of hypotrichia, presenting as a significant reduction in the average numbers of follicles per hair follicle group as compared to domestic shorthair cats, a mild to severe perifollicular to mural lymphocytic infiltration in 77% of observed hair follicle groups, and the follicles are often miniaturized, dilated, and dysplastic. Whole genome sequencing was conducted on a single lykoi cat that was a cross between two independently ascertained lineages. Comparison to the 99 Lives dataset of 194 non‐lykoi cats suggested two variants in the cat homolog for Hairless (HR) (HR lysine demethylase and nuclear receptor corepressor) as candidate causal gene variants. The lykoi cat was a compound heterozygote for two loss of function variants in HR, an exon 3 c.1255_1256dupGT (chrB1:36040783), which should produce a stop codon at amino acid 420 (p.Gln420Serfs*100) and, an exon 18 c.3389insGACA (chrB1:36051555), which should produce a stop codon at amino acid position 1130 (p.Ser1130Argfs*29). Ascertainment of 14 additional cats from founder lineages from Canada, France and different areas of the USA identified four additional loss of function HR variants likely causing the highly similar phenotypic hair coat across the diverse cats. The novel variants in HR for cat hypotrichia can now be established between minor differences in the phenotypic presentations.Peer reviewe

    Multi-omic analyses in Abyssinian cats with primary renal amyloid deposits

    The amyloidoses constitute a group of diseases occurring in humans and animals that are characterized by abnormal deposits of aggregated proteins in organs, affecting their structure and function. In the Abyssinian cat breed, a familial form of renal amyloidosis has been described. In this study, multi-omics analyses were applied and integrated to explore some aspects of the unknown pathogenetic processes in cats. Whole-genome sequences of two affected Abyssinians and 195 controls of other breeds (part of the 99 Lives initiative) were screened to prioritize potential disease-associated variants. Proteome and miRNAome from formalin-fixed paraffin-embedded kidney specimens of fully necropsied Abyssinian cats, three affected and three non-amyloidosis-affected were characterized. While the trigger of the disorder remains unclear, overall, (i) 35,960 genomic variants were detected; (ii) 215 and 56 proteins were identified as exclusive or overexpressed in the affected and control kidneys, respectively; (iii) 60 miRNAs were differentially expressed, 20 of which are newly described. With omics data integration, the general conclusions are: (i) the familial amyloid renal form in Abyssinians is not a simple monogenic trait; (ii) amyloid deposition is not triggered by mutated amyloidogenic proteins but is a mix of proteins codified by wild-type genes; (iii) the form is biochemically classifiable as AA amyloidosis

    A bird's eye view... resistance in academia

    Get PDF
    This article deals with one sociologist's experience of gender inequality in the academy and examines different forms of resistance to it. Here, the author uses the concept of resistance to explore some of the ways faculty women respond to a situation of hierarchical and numerical male dominance. Focusing on faculty women within the hierarchical and numerically male dominated structures of academia, the author identifies seven types of resistance. It also compares the Irish trends as regards the proportion of women in academia to other countries. It is important to stress the methodological limitations of this paper. The author draws on personal observations of the position of faculty women in three of the five academic organisations in which she was employed at various times over the past 30 years (the early 1970s; the 1980s; and the 1990s respectively), initially as research assistant and more recently as professor. It thus can be seen as a personal account: there are 'no empirical findings in the positivist sense' (Lentin, 2000). Observations were not recorded systematically over the years and the possibility that they constitute a highly idiosyncratic perception of the academy cannot be eliminated. A focus on reflexivity and autobiography is part of an epistemological challenge to positivism (Lentin 1993 and 2000; Goode 1998) albeit one that has been viewed with considerable scepticism by many sociologists. Nevertheless, in a context where there are considerable sensitivities around the collection of qualitative data (because of the size of the country, the small number of academic institutions, and strong norms involving institutional loyalty) this approach is arguably an important source of insight
