Evaluation of impact of beam size on fibre Bragg grating fabrication

Fabrication of gratings has gone a long way since the onset by Kenneth Hill in 1976. Basic fabrication techniques such as holographic and phase-mask which have distinguishing advantages (variable wavelength, and high repeatability consecutively) have since been modified in an effort to combine the advantages of both methods. These basic methods are inherently simple and have few controls, they have been combined and modified over time to enable the possibility of fabricating gratings with complex modulation index and phase profiles.

Benefits of electronic vision enhancement systems (EVES) for the visually impaired

PURPOSE: To examine whether objective performance of near tasks is improved with various electronic vision enhancement systems (EVES) compared with the subject's own optical magnifier. DESIGN: Experimental study, randomized, within-patient design. METHODS: This was a prospective study, conducted in a hospital ophthalmology low-vision clinic. The patient population comprised 70 sequential visually impaired subjects. The magnifying devices examined were: patient's optimum optical magnifier; magnification and field-of-view matched mouse EVES with monitor or head-mounted display (HMD) viewing; and stand EVES with monitor viewing. The tasks performed were: reading speed and acuity; time taken to track from one column of print to the next; follow a route map, and locate a specific feature; and identification of specific information from a medicine label. RESULTS: Mouse EVES with HMD viewing caused lower reading speeds than stand EVES with monitor viewing (F = 38.7, P < .001). Reading with the optical magnifier was slower than with the mouse or stand EVES with monitor viewing at smaller print sizes (P < .05). The column location task was faster with the optical magnifier than with any of the EVES (F = 10.3, P < .001). The map tracking and medicine label identification task was slower with the mouse EVES with HMD viewing than with the other magnifiers (P < .01). Previous EVES experience had no effect on task performance (P > .05), but subjects with previous optical magnifier experience were significantly slower at performing the medicine label identification task with all of the EVES (P < .05). CONCLUSIONS: Although EVES provide objective benefits to the visually impaired in reading speed and acuity, together with some specific near tasks, some can be performed just as fast using optical magnification. © 2003 by Elsevier Inc.

Sharing of value in business relationships:a theoretical model

This paper explores the sharing of value in business transactions. Although there is an increased usage of the terminology of value in marketing (such concepts as value based selling and pricing), as well as in purchasing (value-based purchasing), the definition of the term is still vague. In order to better understand the definition of value, the author’s argue that it is important to understand the sharing of value, in general and the element of power for the sharing of value in particular. The aim of this paper is to add to this debate and this requires us to critique the current models. The key process that the analysis of power will help to explain is the division of the available revenue stream flowing up the chain from the buyer's customers. If the buyer and supplier do not cooperate, then power will be key in the sharing of that money flow. If buyers and suppliers fully cooperate, they may be able to reduce their costs and/or increase the quality of the sales offering the buyer makes to their customer.

Narrative Deliberation? On Storytelling as a Necessary Component of Public Deliberation

This paper deals with the place of narrative, that is, storytelling, in public deliberation. A distinction is made between weak and strong conceptions of narrative. According to the weak one, storytelling is but one rhetorical device among others with which social actors produce and convey meaning. In contrast, the strong conception holds that narrative is necessary to communicate, and argue, about topics such as the human experience of time, collective identities and the moral and ethical validity of values. The upshot of this idea is that storytelling should be a necessary component of any ideal of public deliberation. Contrary to recent work by deliberative theorists, who tend to adopt the weak conception of narrative, the author argues for embracing the strong one. The main contention of this article is that stories not only have a legitimate place in deliberation, but are even necessary to formulate certain arguments in the fi rst place; for instance, arguments drawing on historical experience. This claim, namely that narrative is constitutive of certain arguments, in the sense that, without it, said reasons cannot be articulated, is illustrated by deliberative theory’s own narrative underpinnings. Finally, certain possible objections against the strong conception of narrative are dispelled.

The Plutarch’s Motive of "Descensus Animae" in "Nag Hammadi and the Corpus Hermeticum"

Al evaluar los contactos de Plutarco con otras culturas contemporáneas, los investigadores todavía no han llegado a un consenso acerca de la relación entre el queronense y la literatura cristiano-primitiva. Un buen ejemplo de esto aparece al atender al motivo de la creación del alma humana. La intención de las próximas páginas es, tras un análisis de los textos plutarqueos, atender a estos posibles contactos con NHC, los heresiólogos y el Corpus Hermeticum a fin de dilucidar sus similitudes y diferencias.

El dinero en la historia del pensamiento económico: la teoría monetaria postkeynesiana y su confrontación con la ortodoxia

Las disputas en torno a determinados aspectos del dinero, como su neutralidad y el carácter endógeno o exógeno de la oferta monetaria, han sido permanentes entre las distintas escuelas de pensamiento y autores, estando su origen, probablemente, en la época de desarrollo del pensamiento escolástico. En este artículo pretendemos, en primer lugar, realizar un recorrido cronológico e histórico sobre el tratamiento científico económico del dinero, para, en segundo lugar, poner sobre la mesa la macroeconomía ortodoxa a la que han dado lugar las interpretaciones al respecto, así como los enfoques alternativos frente a este pensamiento dominante. Finalmente, intentamos poner en valor los desarrollos monetarios post-keynesianos, integrados en lo que denominan “Economía Monetaria de Producción”, confrontándolos con la llamada Nueva Síntesis Neoclásica.

HATWALK/ Guerilla Millinery/ Part of the Cultural Olympiad

Stealth Visor for the Duke of Wellington Project HATWALK The 2012 Cultural Olympiad would not have been representative of London's creative industries without fashion design. Sponsored by the Mayor of London brought milliners to organise an alternative to the catwalk format , the designers brought together a Hatwalk, uniting landmark heritage statues, classical and modern, to be crowned with a new bespoke design piece each. Together forming a pedestrian navigation through the Jubilee city, the hats also invited twenty one milliners to consider the specificity of working for the great outdoors. Rigorously tested in wind tunnel laboratory to withstand hurricane wind speeds and squally shows the designs aim to bring the 'exclusive' culture of fashion accessories to the inclusive culture of international festival. Working with new technologies of engineering, such as laser measuring tools, and crane for assemblage and fitting, McLean brings new meaning to the familiar figures of national public authority. Since the storming of the Bastille in revolutionary France it has been traditional for the new order to symbolize change through attacking public statuary. In a similar vein, Hatwalk, invites spectators to reconsider the relationship between distant and lofty personages of power and the sartorial insignia through which their power is signified. Crowned with a revolutionary red ' large plexi punk neon number' the Duke of Wellington, at Wellington arch is the first in the Hatwalk exhibition. The originality of this research consists in the effects of surprise and Brechtian 'de familiarisation' resulting from the unexpected. The effects of this structural carnivalesque inversion of authorities can involve a range of reactions from the disdain of the offended to the laughter and pleasure of the surprised. This strategy of bringing the ludic element of play to the formalised authority of legitimised power is also signified through the conscious use of materials and colour in a monochrome and uniform culture of statuary. Here the difference in materials and visible surface of the design signifies the differences that need to be included within a socio political order before it may takes its place in history as being representative of the people it is entrusted to lead. This research output continues the work that led to the Hat Anthology exhibition (output 1), the Fifty Hats that Changed the World (output 2), the Jamaican Olympic team headwear design ( output 4), and is continued in the design, merchandise, accessories and avant garde artefacts of the House of Flora ( see website). The iterative process of the research brings innovation within continuity to McLean's work. It is difficult to theorise the 'rigour' that is undeniably present in a creative design praxis except in that McLean;s research outputs are always surprising and unexpected.

The Participation of Townspeople Making Music in Public Events in the Low Countries in the Fifteenth Century

Musicians, rhetoricians and crossbowmen, all of them employed by the city of Brussels, acted, sang and played instruments during the "Ommegang" procession in the 15th century in the main square, some of them during other processions, too. In Bruges, instrumentalists and singers took part in the representation of biblical scenes on street corners, which were part of the entry of Philip III the Good, Duke of Burgundy, into the city around the year 1440. The members of the clergy who knew music sang plainchant in all of these three roles, and independent musicians probably participated, too, even though the documents don't name them or describe their function. Except for the disabled, who marched in a procession on their own, the "common people" were only spectators of these events, which were planned in advance. The evidence that remains indicates that the voices of the "common people" remained hidden in these events, which were intended to promote civic unity.

Principal Effectiveness: Middle School Leaders' Perceptions Of Principal Practices To Improve Middle School Reading Achievement

ABSTRACT Title of Document: PRINCIPAL EFFECTIVENESS: MIDDLE SCHOOL LEADERS’ PERCEPTIONS OF PRINCIPAL PRACTICES TO IMPROVE MIDDLE SCHOOL READING ACHIEVEMENT Kathleen R. Brady, Doctor of Education, 2016 Directed By: Dr. John Norris, Department of Education The purpose of this exploratory and descriptive study was to examine school leaders’ perceptions of leadership practices that contribute to principal effectiveness in improving reading achievement in middle schools in a large public school district. The data was gathered through the use of a Web-based survey that was emailed to 97 school based leaders including 20 principals, 40 assistant principals, 17 reading department chairpersons, and 20 professional development lead teachers in middle schools with grade 6-8 and 7-8 configurations. Data were collected and analyzed in order to make inferences about principal practices at middle school. The findings of this study indicated few differences between middle school principals’, assistant principals’, reading department chairpersons’, and professional development lead teachers’ perceptions of principal leadership practices that are most important to and have the greatest impact on student reading achievement success. Furthermore, the findings indicated that participants’ three top ranked resources needed to increase the effectiveness of principals in order to improve reading achievement at middle schools include implementing a collaborative planning protocol to support literacy instruction, adding a reading coach to the middle school staff, and providing professional development activities focused on literacy instruction across the content areas. The results were used to make recommendations that may contribute to middle school principal effectiveness.

Behavioural outcomes of next-generation family members’ commitment to their firm

Are there variations in behaviours and leadership styles of next-generation family members or descendants who join their family business due to different forms of commitment? Evidence from a dual respondent study of 109 Canadian and Swiss family firms suggests that descendants with affective commitment to their family firms are more likely to engage in discretionary activities going beyond the job description, thereby contributing to organizational performance. Next-generation members with normative commitment are more likely to engage in transformational leadership behaviours. Both affectively and normatively motivated next-generation members use contingent reward forms of leadership. A surprising finding of this study is the binding force of normative commitment on positive leadership behaviours of next-generation members. This study empirically tests the generalizability of the three-component model of commitment to family businesses, a context in which different forms of commitment may play a unique role.
