The highly repetitive Rana/Pol III family consists of short, tandemly arrayed sequences, scattered throughout the genomes of Palearctic green water frogs. The repeat unit is about 250 bp in length and is a composite element: it contains a SINE-like retroposon with a tRNA structure, flanked by two short direct repeats, and the occurrence of two internal repeats gives evidence that an additional transposition event may have inserted a segment within the already transposed element. Rana/Pol III family is present in the genomes of Rana lessonae, R. ridibunda, and their hybrid form R. esculenta, as well as in R. shqiperica, R. epeirotica, R. cretensis, and the Italian taxon. These sequences are also present in the Iberian R. perezi, although less abundant, but appear to be lacking in the north African speciesR. saharica. The distribution of Rana/Pol III in the genomes of Palearctic green frogs is in agreement with the phyletic history based on genetic data. The evolutionary pattern proposed for the genus Rana enables us to suppose that the hybridogenetic mechanism is one of the factors accounting for the possible horizontal transfer of Rana/Pol III elements from the central-north Europe species to R. perezi.Key words: repetitive DNA, SINE-like retroposons, hybridogenesis, Rana esculenta group.

<p>This chapter mines the literature to bring out the richness and heterogeneity of Chinese rock. The first part charts the geography of music as the intersection of situated material space and networked topology. Chinese rock thus assembles disparate elements from the two wests: the capitalist-west and, the western China of the silk roads. The second part addresses the live rock scenes that has mushroomed in cities, some as forces of dissenters, some as state-sanctioned role models, or, as a hybrid form of both. </p>

As pioneers of new ideas and practices, many entrepreneurial journalists spearhead the change of journalism towards hybridity. By applying appraisal theory, this article examines a hybrid of objectivity and dialogue in daily news articles by five entrepreneurial journalism outlets – Axios, MustRead, National Observer, The Skimm and the Voice of San Diego. For comparative purposes, a dataset from three legacy media outlets was also analysed. The results show that the entrepreneurial journalism outlets employ journalistic dialogue in otherwise stylistically objective news texts notably more often than do legacy media outlets. Dialogic registers provide subtle, non-partisan assessments of events and issues and make the news more informal. Such a hybrid form of journalism serves the functions of sense-making, establishing an interpersonal connection between ‘private’ audiences and ‘public’ news, and connecting journalism with fields outside of its core. By doing so, the hybrid journalism of entrepreneurial journalists offers a distinctive vision of the futures of news journalism.

Religion is a key site for constructions of masculinity, and visions of a gender equal society must include religious men. This study examines how a group of British white, heterosexual, middle-class, lay Anglican men construct masculinities via discourses on church-going, worship styles, and godly submission. The interviewed men express a hybrid form of masculinity, informed by religious faith, that embraces typically “feminine” characteristics such as love, humility, and vulnerability. At the same time, they articulate ideals of heteronormativity and essentialized gender differences that support hegemonic masculinity. The participants engage simultaneously in a selective, “discursive distancing” from, and a discursive alignment with, hegemonic masculinity norms, thus revealing tensions between competing masculinity norms.

Abstract This essay stems from our growing concern about the carbon intensity of academia, and of conferencing as an epitome of this. Face-to-face conferencing is widely recognised as both unsustainable and inequitable. Against this backdrop, digital conferencing (online only, or in hybrid form) offers a viable alternative. However, shifting to digital forms of conferencing does not automatically bring about equity. Drawing on white papers, academic discussions and results from a PollEverywhere survey, this essay explores issues of sustainability and equity across modes of face-to-face and digital conferencing, with the aim of charting a path towards more sustainable and accessible digital practises for a diverse community of linguists.
