Storytelling, women's authority and the 'Old-Wife's Tale': 'The Story of the Bottle of Medicine'
No full textThe focus of this article is a single personal narrative – a Shetland woman’s telling of a story about two girls on a journey to fetch a cure for a sick relative from a wise woman. The story is treated as a cultural document which offers the historian a conduit to a past that is respectful of indigenous woman-centred interpretations of how that past was experienced and understood. The ‘story of the bottle of medicine’ is more than a skilful telling of a local tale; it is a memory practice that provides a path to a deeper and more nuanced understanding of a culture. Applying perspectives from anthropology, oral history and narrative analysis, three sets of questions are addressed: the issue of authenticity; the significance of the narrative structure and storytelling strategies employed; and the nature of the female performance. Ultimately the article asks what this story can tell us about women’s interpretation of their own history
Reconstructing the evolution of the Ironside Mountain batholith, northern California through textural and single-mineral compositional analyses of pyroxene, amphibole, and plagioclase
No full textThe ~170-168 Ma Ironside Mountain batholith in northern California encompasses the Ironside Mountain pluton, quartz diorite of Happy Camp Mountain, Wildwood pluton, West China Peak complex, and Denny complex. The Ironside Mountain batholith was emplaced within ca. two m.y. after regional thrusting attributed to the Siskiyou orogeny. Single-mineral compositions in clinopyroxene, hornblende, and plagioclase were measured in-situ by electron-probe micro-analyses and laser ablation inductively coupled plasma mass spectrometry and coupled with bulk rock X Ray Fluorescence analyses.
Mineral data revealed two compositionally diverse magmas within the Ironside Mountain batholith: A) those of the Ironside Mountain pluton, quartz diorite of Happy Camp Mountain, and Wildwood pluton, which are characterized by two- and three-pyroxene assemblages + ilmenite +magnetite, scant amphibole and biotite, low Mg number, low Cr concentrations, and rare earth element abundances in clinopyroxene and amphibole to 300 times chondrites with deep negative europium anomalies; and B) those of the Denny and West China peak complexes, which are characterized by 2-pyroxene assemblages, have rare earth element abundances in clinopyroxene and amphibole to 50 and 100 times chondrites, respectively, with small to absent europium anomalies. Europium anomalies in clinopyroxene and amphibole of group A suggest crystallization from plagioclase-fractionated melts. Early plagioclase crystallization indicates magmas with low f(H2O). Small to absent europium anomalies in clinopyroxene and hornblende of group B suggests these minerals were liquidus phases without plagioclase, which indicates higher f(H2O). Lower Cr abundances and Mg numbers in clinopyroxene and amphibole from group A suggests their magmas were evolved.
Rimming relationships between clinopyroxene, orthopyroxene, and inverted pigeonite, and the absence of clear fractionation trends in major and trace element data of pyroxene and amphibole indicates magmas of the Ironside Mountain pluton did not evolve as a single closed system. Iron-Mg exchange coefficients higher than equilibrium values in amphibole, clinopyroxene, and orthopyroxene; Ab-An exchange coefficients higher than equilibrium values in plagioclase; and the fact that melts calculated from augite compositions display deep negative europium anomalies, but such anomalies are absent in bulk rock rare earth element patterns, indicates partial accumulation of Ca-rich plagioclase, orthopyroxene, and clinopyroxene occurred.
Clinopyroxene and amphibole compositions from the Ironside Mountain pluton and coeval Wildwood pluton are distinct from those of the Western Hayfork arc. Barnes and Barnes (2020) showed the predominant magma types erupted from the Western Hayfork arc were calc-alkaline or high-Mg andesites and dacites, the latter of which experienced fractionation of garnet at depth. The lack of negative europium anomalies in Western Hayfork augite and hornblende suggests plagioclase was absent early in the crystallization history, which is further evidence of H2O-rich and oxidized magmas (Muntener and others, 2001). Along with the geologic relationships reported by Barnes and others (2006), the compositional distinctions between Western Hayfork arc and Ironside Mountain pluton parental magmas refute the hypothesis that the Ironside Mountain pluton is the intrusive equivalent of the Western Hayfork arc.Restricted until 06/2027.

The socio-cultural milieux of the left in post-war Britain
No full textThis thesis examines the relationship between activist subjectivities and the shaping of Britain’s late
sixties extra-parliamentary left cultures. Based on the oral narratives of ninety men and women, it
traces the activist trajectory from child to adulthood to understand the social, psychological, and
cultural processes informing the political and personal transformation of young adults within the
new left cultures that emerged in the wake of Britain’s anti-war movement, the Vietnam Solidarity
Campaign (VSC). To this end the study charts the development of the political and cultural shifts on
the left over the decade from the early 1960s to the early 1970s. It shows how throughout this
period dialogue between inner and outer activist life occurred against a background of ongoing
realignment on the left from a fluid, eclectic cultural network around the VSC to a demarcated post-
VSC left after 1969, that saw increasing divergence between a non-aligned libertarian New Left on
the one hand and a Trotskyist far left milieu on the other.
The study seeks to claim a valid space for Britain’s left activist landscape within the political,
social and cultural framework of ‘1968’ and British post-war historiography. Privileging individual
and collective subjectivities, the thesis examines ways of belonging inside Trotskyist and non-aligned
left milieux by situating the respondents, their radical histories and activist cultures within the
changing post-war fabric. It shows that investigating individual and collective memories provides
deeper understanding of the ‘cognitive maps’ that young men and women created, as they
attempted to situate themselves as radical, global beings as well as local, gendered social citizens.
As micro-studies the individual stories reveal how the experience of social, emotional and
political maturation from child to adult intersected with a specific social and political moment – the
formation of a new and distinctive left culture that came to full fruition only in the aftermath of 1968
with the arrival of Women’s Liberation and the new personal politics. Exploring the social and
psychological impact of post-war childhood and youth, the study engages with the political and
emotional impact of Women’s Liberation on the men and women within the cultural context of the different left milieux.
Overall, the thesis questions how, from the mid-1960s to the early 1970s, the variant
cultures of the milieux penetrated public and private spaces, and shaped early life experiences of
work, political activity, family, and political and personal relations in order to understand how
activism shaped social patterns and psychic being

Nocturnal pollination: An overlooked ecosystem service vulnerable to environmental change
No full text© 2020 The Author(s). This is an open access article published by Portland Press Limited on behalf of the Biochemical Society and the Royal Society of Biology and distributed under the Creative Commons Attribution License 4.0 (CC BY). Existing assessments of the ecosystem service of pollination have been largely restricted to diurnal insects, with a particular focus on generalist foragers such as wild and honey bees. As knowledge of how these plant-pollinator systems function, their relevance to food security and biodiversity, and the fragility of these mutually beneficial interactions increases, attention is diverting to other, less well-studied pollinator groups. One such group are those that forage at night. In this review, we document evidence that nocturnal species are providers of pollination services (including pollination of economically valuable and culturally important crops, as well as wild plants of conservation concern), but highlight how little is known about the scale of such services. We discuss the primary mechanisms involved in night-time communication between plants and insect pollen-vectors, including floral scent, visual cues (and associated specialized visual systems), and thermogenic sensitivity (associated with thermogenic flowers). We highlight that these mechanisms are vulnerable to direct and indirect disruption by a range of anthropogenic drivers of environmental change, including air and soil pollution, artificial light at night, and climate change. Lastly, we highlight a number of directions for future research that will be important if nocturnal pollination services are to be fully understood and ultimately conserved
Exploring the effects of mediumship on hope, resilience, and post-traumatic growth in the bereaved
No full textIn previous decades there has been a lack of research into what people who sit with mediums gain from this process in terms of psychological benefits. Taking a positive psychology perspective, a qualitative approach was used to explore the effect that mediumship has on the bereaved. Seven participants gave retrospective accounts of a sitting which was felt to be meaningful to them, explaining reasons for this belief. This was explored using a thematic analysis. Findings suggested that mediumship appeared to furnish some resilience. Coping which appears linked to hope, linked to post-traumatic growth and also appears to be enhanced when someone experiencing a sitting with a medium believes they have had confirmation of survival of the deceased. Hope appeared to be increased, and resilience and coping were reported as strengthened after a subjectively meaningful sitting with a medium. The implication therefore is that mediumship appeared to offer positive psychological tools to enable better coping styles post-bereavement. This study has been condensed and updated from the original dissertation research conducted by the lead author (Bains, 2014 (now Cox)) and supervised by Smith
Heterogeneous firms and trade costs: a reading of French access to European agro-food market
No full textThis article offers a new reading of intra-European trade based on recent developments in new international economics (Melitz, 2003; Chaney, 2008). These models take the heterogeneity of firms into account and offer a micro-economic analysis of the process of selection at work for firms entering markets. An exporting firm has to bear certain specific costs to break into a market, and only sufficiently productive firms are able to do so. Using individual data for French agro-food firms and the distribution of their exports across European markets, this article shows that access conditions to the various European markets are not identical for French firms: the Belgian market would seem to be a natural extension of the French market, whereas the markets of small, distant countries (Austria, Finland or Sweden) are the least accessible. Econometric analysis based on analysis both of the firm selection process and of the value of their exports shows that the standard geographical variables (distance, country size) affecting the single European market still play a major role in the choice of export markets. Results also reveal that there are still remaining trade costs at entry to the different European markets; but these trade frictions don’t matter to all firms in the same way. The higher the firm experience, the lower the impact of trade costs.firm heterogeneity, trade costs, European Integration., International Relations/Trade,
