Winslow Homer and aestheticism, 1865-1880:
No full textThis dissertation explores the introduction of aestheticism to the United States through a close examination of the work of Winslow Homer from 1865 to 1880. I argue that Homer was consistently engaged with aestheticism from its early introduction to the United States in the years immediately following the Civil War. Throughout Homer’s career, aestheticism was not antithetical to realism, but an alternative approach to addressing the social and cultural changes of modern life. Homer drew from many cultural precedents and models to create an aestheticism that was not only representative of his individuality, but also uniquely American. In Chapter One, I explore the introduction of aestheticism to the United States through a review of contemporary writings, particularly that of Homer’s friend Eugene Benson, connecting these theories to the building of American cultural standards and institutions, in which Homer was actively involved during this period. Chapter Two examines Homer’s early exposure to European aestheticism, including an awareness of aesthetic paintings at the 1867 Exposition Universelle in Paris, particularly the works of James McNeil Whistler. Since many of these early aesthetic works depict female figures, I likewise consider the gender implications of Homer’s work in this vein. Chapter Three examines Homer’s work from around the year 1875 when he began exhibiting aestheticist works more public exhibitions. Here, the critical response to his work plays an increased role in defining aestheticism’s progress in America. I examine the tensions that emerged in Homer’s work that grew from the critical expectation to ground his paintings with moral and realistic overtones while he simultaneously exploring issues of ideal beauty that developed in the aestheticist debate. Chapter Four studies Homer’s tile production from the late 1870s, exploring precedents as well as contemporary uses of tiles and other decorative arts in relationship to Homer’s work from this period. It examines the implications of the subjects that Homer used in these new experimental works, arguing that Homer’s work in this vein functioned within a complete decorative scheme that reflected the patrons’ morals and social fashioning.Ph.D.Includes bibliographical references (p. 344-367)by Ashley Lyn Atkin
Author Co-Citation Analysis (ACA): a powerful tool for representing implicit knowledge of scholar knowledge workers
No full textIn the last decade, knowledge has emerged as one of the most important and valuable organizational assets. Gradually this importance caused to emergence of new discipline entitled ―knowledge management‖. However one of the major challenges of knowledge management is conversion implicit or tacit knowledge to explicit knowledge. Thus Making knowledge visible so that it can be better accessed, discussed, valued or generally managed is a long-standing objective in knowledge management. Accordingly in this paper author co- citation analysis (ACA) will be proposed as an efficient technique of knowledge visualization in academia (Scholar knowledge workers)
A Guide to Instrumentalism: Initial Teacher Education in the Lifelong Learning Sector
No full textThis paper provides a critique of the competence based approach to teacher education in the Learning and Skills Sector. This critique is made at a time of consultation of proposed developments to the current standards, which are due for implementation from 2012 and which will involve only minor changes. The existing, Lifelong Learning UK (LLUK) standards were introduced in September 2006 following withdrawal of the old FENTO standards (FENTO, 1999) which had been subject to criticism that they did not meet the needs of trainee teachers and did not adequately reflect the developmental nature of Initial Teacher Education (ITE). The revised standards were intended to reflect this developmental process, and to contribute raising standards and the ‘professionalisation’ of the sector (DfES/Standards Unit 2004); however, even before their introduction concerns were raised about over-regulation (Lucas, 2004:49).
Despite a significant level of investment in the new standards, what eventually emerged has been subject to even greater criticism than the FENTO standards (e.g. see Lucas, 2007; Finlay et al 2007; Gleeson and James, 2007 and Simmons and Thompson 2007). Key features in this criticism have been the narrow concept of learning and skills, and the lack of recognition of both the wider dimensions of professional practice and the importance of knowledge. Contextualised within this literature, this paper argues that the detailed and prescriptive competency based structure of contemporary teacher training in the FE sector, together with wider regulation such as Ofsted and LLUK endorsement requirements, is productive of teachers who are instrumental and conformist but who lack the knowledge to engage with the concerns for social justice which are fundamental to working in the FE sector. In turn, these teachers deliver an instrumental and competency based vocational curriculum which, the paper argues, is complicit with other systems and structures in education in the reproduction of labour and of social class.
The paper also draws on literature addressing issues around assessment (Ecclestone, 2010) and professionalism (e.g. Gleeson and James, 2007; Bathmaker, 2006) as well as class based critiques of the FE system which draw on work by, amongst others, Avis, (2007), Atkins (2009) and Colley (2006). The arguments in this paper are also supported by a deconstruction of the current standards. This deconstruction has been used to identify what is – and is not – supported or promoted by the standards in the context of education and wider notions of professionalism and to problematise them in the context of contemporary literature

Active X-ray optics for the next generation of X-ray space telescopes
No full textDescribed within is the design, manufacture, metrology and X-ray testing of an active X-ray
prototype intended for the next generation of X-ray telescopes. One of the challenges faced by
the X-ray telescope community is how to combine high resolution and high sensitivity into one
system, as weight limitations place constraints on the optics that can be launched. Therefore the
mandate of the active X-ray prototype is to provide high sensitivity through the ability of the optics
to be nested and to deliver high angular resolution through the active control of the optic’s form.
Piezoelectric unimorph actuators provide the active component: it is intended that they will correct
for figure errors within the optic and therefore increase the angular resolution capability.
The prototype’s design is based upon an ellipsoidal segment which provides point-to-point
focussing of an X-ray source. The prototype itself is composed of an electroformed nickel optic
where the non-reflective surface is populated with 30 piezoelectric actuators and it is the production
of the prototype that is the core of the presented research. Metrology of the actuators’ influence
functions is presented and highlight the prototype’s ability to deform its optic surface by microns.
In addition, the measured influence functions are compared against finite element models and a
distinct similarity between the functions is observed.
The prototype was tested at an X-ray beamline facility in November 2008 and the results
showed the prototype’s ability to correct the optic to achieve an improved angular resolution: from
0.786 arc-minutes to 0.686 arc-minutes in terms of full width half maximum. Finally, difficulties
in the manufacture of the prototype and X-ray testing shall be presented alongside future work in

Cardiovascular effects and fatalities associated with intravenous administration of doxycycline to horses and ponies
No full textIntravenous use of doxycycline in horses is associated with deleterious side effects on the cardiovascular system which may result in fatalities. At dosages and infusion rates used in these studies, supraventricular tachycardia, systemic arterial hypertension, clinical signs of discomfort, collapse and death were observed. Results of the present study suggest that the intravenous use of doxycycline should be avoided in horses.LR: 20031114; PUBM: Print; JID: 0173320; 0 (Electrolytes); 564-25-0 (Doxycycline); ppublishSource type: Electronic(1
A review of traditional and novel treatments for seizures in autism spectrum disorder: findings from a systematic review and expert panel
No full textabstract: Despite the fact that seizures are commonly associated with autism spectrum disorder (ASD), the effectiveness of treatments for seizures has not been well studied in individuals with ASD. This manuscript reviews both traditional and novel treatments for seizures associated with ASD. Studies were selected by systematically searching major electronic databases and by a panel of experts that treat ASD individuals. Only a few anti-epileptic drugs (AEDs) have undergone carefully controlled trials in ASD, but these trials examined outcomes other than seizures. Several lines of evidence point to valproate, lamotrigine, and levetiracetam as the most effective and tolerable AEDs for individuals with ASD. Limited evidence supports the use of traditional non-AED treatments, such as the ketogenic and modified Atkins diet, multiple subpial transections, immunomodulation, and neurofeedback treatments. Although specific treatments may be more appropriate for specific genetic and metabolic syndromes associated with ASD and seizures, there are few studies which have documented the effectiveness of treatments for seizures for specific syndromes. Limited evidence supports l-carnitine, multivitamins, and N-acetyl-l-cysteine in mitochondrial disease and dysfunction, folinic acid in cerebral folate abnormalities and early treatment with vigabatrin in tuberous sclerosis complex. Finally, there is limited evidence for a number of novel treatments, particularly magnesium with pyridoxine, omega-3 fatty acids, the gluten-free casein-free diet, and low-frequency repetitive transcranial magnetic simulation. Zinc and l-carnosine are potential novel treatments supported by basic research but not clinical studies. This review demonstrates the wide variety of treatments used to treat seizures in individuals with ASD as well as the striking lack of clinical trials performed to support the use of these treatments. Additional studies concerning these treatments for controlling seizures in individuals with ASD are warranted.View the article as published at http://journal.frontiersin.org/article/10.3389/fpubh.2013.00031/ful
