Otherworlds: fantasy and history in medieval literature

This book offers a new perspective on the otherworlds of medieval literature. These fantastical realms are among the most memorable places in medieval writing, by turns beautiful and monstrous, alluring and terrifying. Passing over a river or sea, or entering into a hollow hill, heroes come upon strange and magical realms. These places are often very beautiful, filled with sweet music and adorned with precious stones and rich materials. There is often no darkness, time may pass at a different pace, and the people who dwell there are usually supernatural. Sometimes such a place is exactly what it appears to be-the land of heart's desire-but, the otherworld can also have a sinister side, trapping humans and keeping them there against their will. Otherworlds: Fantasy and History in Medieval Literature takes a fresh look at how medieval writers understood these places and why they found them so compelling. It focuses on texts from England, but places this material in the broader context of literary production in medieval Britain and Ireland. The narratives examined in this book tell a rather surprising story about medieval notions of these fantastical places. Otherworlds are actually a lot less 'other' than they might initially seem. Authors often use the idea of the otherworld to comment on very serious topics. It is not unusual for otherworld depictions to address political issues in the historical world. Most intriguing of all are those texts where locations in the real world are re-imagined as otherworlds. The regions on which this book focuses, Britain, Ireland and the surrounding islands, prove particularly susceptible to this characterization.

Far-red light filtering by plastic film, greenhouse-cladding materials: effects on growth and flowering in Petunia and Impatiens

Photoselective plastic films with low transmission to far-red (FR) light (700-800 nm) are now available so that plants grown in greenhouses clad with such plastics exhibit reduced stem extension and, consequently, plant height. Here we compare the action of three FR-absorbing polythene films on extension growth of Petunia (Petunia X hybrida) cv. 'Express Blue' and Impatiens walleriana cv. 'Accent Deep Pink' with plants grown under a control polythene film (standard UVI/EVA film). Half of the plants under the control film were treated with a chemical plant growth regulator (PGR; diaminozide, B-Nine) and half were sprayed with water alone. Possible negative effects of such film plastics on flowering, and on fresh and dry weight accumulation, were also quantified. Plants were harvested destructively when all plants in each treatment had reached the first open flower stage. In Petunia, plant height was reduced by all three FR-filtering films and by PGR-treatment. The FR-filtering films giving the highest R:FR ratios also reduced plant height in Impatiens. Leaf number, leaf area and total dry Weight in both species. were greatest in the controls and smallest under films with the lowest PAR transmission. The film giving the highest R:FR ratio and PAR transmission also produced the most compact Petunia plants;, while the film. with. the lowest PAR transmission produced the least compact plants in both species. There was no significant effect of treatments on time to first flower in Impatiens. However, Petunia plants under low PAR transmission films took longer to flower. Plastic-films which filter out FR light to increase the R:FR ratio, combined With high PAR transmission, can therefore be used as an alternative to conventional PGRs.

Evaluation of dichroic material for enhancing light pipe/natural ventilation and daylighting in an integrated system

Integration of natural ventilation and daylighting in a single installation would make both technologies more attractive. One method for the integration is the use of concentric light pipe and ventilation stack. By constructing the light pipe using dichroic materials, the infrared part of the solar radiation is allowed to be transmitted to the stack but the visible light is guided by the light pipe into a room. The heat gain to the interior can be reduced and the thermal stack effect strengthened. Work presented here involved the experimental and computational evaluation of dichroic materials for enhancing both natural stack ventilation and daylighting. The transmittance of a dichroic light pipe was found to be similar to that of a light pipe with a 95% specular reflectance. The infra-red radiation transmitted through the dichroic material into a passive stack was found to enhance the natural ventilation flow by up to 14%. The effect is greater in summer than in winter, which is highly desirable as there is often a lack of driving force for natural stack ventilation in summer.

Development of colour and firmness in strawberry crops is UV light sensitive, but colour is not a good predictor of several quality parameters

BACKGROUND: Strawberry (Fragaria × ananassa Duchesne var. Elsanta) plants were grown in polytunnels covered with three polythene films that transmitted varying levels of ultraviolet (UV) light. Fruit were harvested under near-commercial conditions and quality and yield were measured. During ripening, changes in the colour parameters of individual fruit were monitored, and the accuracy of using surface colour to predict other quality parameters was determined by analysing the correlation between colour and quality parameters within UV treatments. RESULTS: Higher exposure to UV during growth resulted in the fruit becoming darker at harvest and developing surface colour more quickly; fruit were also firmer at harvest, but shelf life was not consistently affected by the UV regime. Surface colour measurements were poorly correlated to firmness, shelf life or total phenolics, anthocyanins and ellagic acid contents. CONCLUSION: Although surface colour of strawberry fruits was affected by the UV regime during growth, and this parameter is an important factor in consumer perception, we concluded that the surface colour at the time of harvest was, contrary to consumer expectations, a poor indicator of firmness, potential shelf life or anthocyanin content.

British pharmacy professionals’ beliefs and participation in continuing professional development: a review of the literature.

Objectives Continuing professional development (CPD) has potential to be useful in pharmacy revalidation but past uptake and attitudes to CPD in Great Britain (GB) need to be mapped. This review examines published literature to chart the participation and beliefs of pharmacy professionals towards CPD in GB in a decade that had seen a formal transition from continuing education to CPD. Methods A comprehensive review of the published literature was conducted to identify studies of the uptake of, or attitudes towards, CPD cross different sectors of pharmacy in GB from 2000 to 2010. Key findings Twenty-two studies were included and analysed, including 13 research papers, six conference papers, two news items reporting survey outcomes and one commissioned study. Eight barriers to CPD were identified as: time, financial costs and resource issues, understanding of CPD, facilitation and support for CPD, motivation and interest in CPD, attitudes towards compulsory CPD, system constraints, and technical problems. Pharmacy professionals on the whole agreed with the principle of engaging with CPD but there was little evidence to suggest widespread and wholehearted acceptance and uptake of CPD, essential for revalidation. Conclusions If CPD is to succeed, people's beliefs and attitudes must be addressed by recognising and modifying perceived barriers through a combination of regulatory, professional, work-related and personal channels. A number of recommendations are made. Direct experience of effective CPD in the absence of perceived barriers could impact on personal development, career development and patient benefit thus strengthening personal beliefs in the value of CPD in an iterative manner.

Winckelmann and the invention of antiquity: history and aesthetics in the age of Altertumswissenschaft

This volume provides a new perspective on the emergence of the modern study of antiquity, Altertumswissenschaft, in eighteenth-century Germany through an exploration of debates that arose over the work of the art historian Johann Joachim Winckelmann between his death in 1768 and the end of the century. This period has long been recognised as particularly formative for the development of modern classical studies, and over the past few decades has received increased attention from historians of scholarship and of ideas. Winckelmann's eloquent articulation of the cultural and aesthetic value of studying the ancient Greeks, his adumbration of a new method for studying ancient artworks, and his provision of a model of cultural-historical development in terms of a succession of period styles, influenced both the public and intra-disciplinary self-image of classics long into the twentieth century. Yet this area of Winckelmann's Nachleben has received relatively little attention compared with the proliferation of studies concerning his importance for late eighteenth-century German art and literature, for historians of sexuality, and his traditional status as a 'founder figure' within the academic disciplines of classical archaeology and the history of art. Harloe restores the figure of Winckelmann to classicists' understanding of the history of their own discipline and uses debates between important figures, such as Christian Gottlob Heyne, Friedrich August Wolf, and Johann Gottfried Herder, to cast fresh light upon the emergence of the modern paradigm of classics as Altertumswissenschaft: the multi-disciplinary, comprehensive, and historicizing study of the ancient world.

Ancillary narratives: maids, sleepwalking, and agency in nineteenth-century literature and culture

The limited coverage of servants in nineteenth-century literature may plausibly be ascribed to the tenuous nature of the roles they play in primary texts, and especially to the problematic nature of their agency. This idea is implicit in the arguments of Bruce Robbins, whose The Servant’s Hand remains the most cogent approach to giving servants a palpable role in critical narrative: for Robbins, the agency that acts through the servant ‘prosthesis’ rebounds on the master, granting the servant figure a sometimes exorbitant textual agency. The figure of the sleepwalking maid, and the analogies between sleepwalking and domestic service implicit in it, will help to complicate this picture. In anecdotes of spontaneous sleepwalking, and their subsequent appropriation by mesmerists, maids are cast as non-agents in terms of ownership of narrative: their subjectivity is immaterial to the public fate of the story which their acts generate. But this apparent non-agency is itself derived from their spontaneity; from an autonomous, albeit unconscious, self-will. As such, sleepwalking subjectivity is a gift to paternalism; a mastery it does not have to produce. In conclusion, it is this undetermined quality, rather than a simple lack of agency, that characterizes the maid in the novel, and which continues to exclude domestic servants from critical narrative.

Using coordinated observations in polarized white light and Faraday rotation to probe the spatial position and magnetic field of an interplanetary sheath

Coronal mass ejections (CMEs) can be continuously tracked through a large portion of the inner heliosphere by direct imaging in visible and radio wavebands. White light (WL) signatures of solar wind transients, such as CMEs, result from Thomson scattering of sunlight by free electrons and therefore depend on both viewing geometry and electron density. The Faraday rotation (FR) of radio waves from extragalactic pulsars and quasars, which arises due to the presence of such solar wind features, depends on the line-of-sight magnetic field component B ∥ and the electron density. To understand coordinated WL and FR observations of CMEs, we perform forward magnetohydrodynamic modeling of an Earth-directed shock and synthesize the signatures that would be remotely sensed at a number of widely distributed vantage points in the inner heliosphere. Removal of the background solar wind contribution reveals the shock-associated enhancements in WL and FR. While the efficiency of Thomson scattering depends on scattering angle, WL radiance I decreases with heliocentric distance r roughly according to the expression Ir –3. The sheath region downstream of the Earth-directed shock is well viewed from the L4 and L5 Lagrangian points, demonstrating the benefits of these points in terms of space weather forecasting. The spatial position of the main scattering site r sheath and the mass of plasma at that position M sheath can be inferred from the polarization of the shock-associated enhancement in WL radiance. From the FR measurements, the local B ∥sheath at r sheath can then be estimated. Simultaneous observations in polarized WL and FR can not only be used to detect CMEs, but also to diagnose their plasma and magnetic field properties.
