Religious Tastes and Styles as Markers of Class Belonging: A Bourdieuian Perspective on Pentecostalism in South America

Studies on the relationship between social class and religion tend to highlight the demographic dimension of class, but neglect its symbolic dimension. By addressing the symbolic dimensions through a Bourdieuian approach, this article contends that religious tastes and styles can be employed as class markers within the sphere of religion. A case study on Argentinean Pentecostalism and in-depth analysis of a lower and middle class church illustrate how symbolic class differences are cultivated in the form of distinctive religious styles. While the lower class church displays a style marked by emotional expressiveness and the search for life improvement through spiritual practices, the middle class church performs a sober and calm style of Pentecostalism. The study highlights the role of styles in the reproduction of class boundaries, while shedding a critical light on the importance of tastes

The Sch9 kinase is a chromatin-associated transcriptional activator of osmostress-responsive genes

The yeast Sch9 kinase has been implicated in the cellular adjustment to nutrient availability and in the regulation of aging. Here, we define a novel role for Sch9 in the transcriptional activation of osmostress inducible genes. Loss-of-function mutants sch9 are sensitive to hyperosmotic stress and show an impaired transcriptional response upon osmotic shock of several defense genes. We show that Sch9 is required for gene expression regulated by Sko1, a transcription factor, which is directly targeted by the Hog1 MAP kinase. Sch9 interacts in vitro with both Sko1 and Hog1. Additionally, Sch9 phosphorylates Sko1 in vitro. When artificially tethered to promoter DNA, Sch9 strongly activates transcription independently of osmotic stress. Using in vivo chromatin immunoprecipitation, we demonstrate that Sch9 is recruited to the GRE2 and CTT1 genes exclusively under osmostress conditions, and that this recruitment is dependent on Hog1 and Sko1. Furthermore, Sch9 is required for the proper recruitment of Hog1 at the same genes. Our data reveal the complexity of stress-induced transcription by the regulated association of signaling kinases to chromatin

Fossil isopod and decapod crustaceans from the Kowai formation (pliocene) near Makikihi, South Canterbury, New Zealand

Small concretions and specimens embedded in the matrix have yielded a new Pliocene crustacean fauna from the Kowai Formation near Makikihi, South Canterbury, New Zealand. The fauna is relatively robust, with five identifiable taxa. Three new species are named herein, including the isopod Cirolana makikihi and the decapods Upogebia kowai and Austrohelice manneringi. One new genus and species of decapod, Kowaicarcinus maxwellae, is also named. The fauna documents the second occurrences of fossil isopod and upogebiid from New Zealand. The fauna is indicative of a nearshore setting with some mixing with taxa from shallow, offshore, normal marine settings

An atlas of larval organogenesis in the European shore crab Carcinus maenas L. (Decapoda, Brachyura, Portunidae)

Abstract Background The life history stages of brachyuran crustaceans include pelagic larvae of the Zoea type which grow by a series of moults from one instar to the next. Zoeae actively feed and possess a wide range of organ systems necessary for autonomously developing in the plankton. They also display a rich behavioural repertoire that allows for responses to variations in environmental key factors such as light, hydrostatic pressure, tidal currents, and temperature. Brachyuran larvae have served as distinguished models in the field of Ecological Developmental Biology fostering our understanding of diverse ecophysiological aspects such as phenotypic plasticity, carry-over effects on life-history traits, and adaptive mechanisms that enhance tolerance to fluctuations in environmental abiotic factors. In order to link such studies to the level of tissues and organs, this report analyses the internal anatomy of laboratory-reared larvae of the European shore crab Carcinus maenas. This species has a native distribution extending across most European waters and has attracted attention because it has invaded five temperate geographic regions outside of its native range and therefore can serve as a model to analyse thermal tolerance of species affected by rising sea temperatures as an effect of climate change. Results Here, we used X-ray micro-computed tomography combined with 3D reconstruction to describe organogenesis in brachyuran larvae. We provide a detailed atlas of the larval internal organization to complement existing descriptions of its external morphology. In a multimethodological approach, we also used cuticular autofluorescence and classical histology to analyse the anatomy of selected organ systems. Conclusions Much of our fascination for the anatomy of brachyuran larvae stems from the opportunity to observe a complex organism on a single microscopic slide and the realization that the entire decapod crustacean bauplan unfolds from organ anlagen compressed into a miniature organism in the sub-millimetre range. The combination of imaging techniques used in the present study provides novel insights into the bewildering diversity of organ systems that brachyuran larvae possess. Our analysis may serve as a basis for future studies bridging the fields of evolutionary developmental biology and ecological developmental biology
