The anti-neutrino source properties of a fission reactor are governed by the production and beta decay of the radionuclides present and the summation of their individual anti-neutrino spectra. The fission product radionuclide production changes during reactor operation and different fissioning species give rise to different product distributions. It is thus possible to determine some details of reactor operation, such as power, from the anti-neutrino emission to confirm safeguards records. Also according to some published calculations, it may be feasible to observe different anti-neutrino spectra depending on the fissile contents of the reactor fuel and thus determine the reactor's fissile material inventory during operation which could considerable improve safeguards. In mid-2014 the University of Liverpool deployed a prototype anti-neutrino detector at the Wylfa R1 station in Anglesey, United Kingdom based upon plastic scintillator technology developed for the T2K project. The deployment was used to develop the detector electronics and software until the reactor was finally shutdown in December 2015. To support the development of this detector technology for reactor monitoring and to understand its capabilities, the National Nuclear Laboratory modelled this graphite moderated and natural uranium fuelled reactor with existing codes used to support Magnox reactor operations and waste management. The 3D multi-physics code PANTHER was used to determine the individual powers of each fuel element (8×6152) during the year and a half period of monitoring based upon reactor records. The WIMS/TRAIL/FISPIN code route was then used to determine the radionuclide inventory of each nuclide on a daily basis in each element. These nuclide inventories were then used with the BTSPEC code to determine the anti-neutrino spectra and source strength using JEFF-3.1.1 data. Finally the anti-neutrino source from the reactor for each day during the year and a half of monitored reactor operation was calculated. The results of the preliminary calculations are shown and limitations in the methods and data discussed.

Abstract Waste is generated on daily basis through different activities of human beings, which leads to pollution of the environment, which may have serious implications on the health of the individual. Waste generation is also a big problem in schools and universities. To keep that problem in mind study has been conducted on the campus of CCSHAU, Hisar; with the objective to study the type and volume of waste generated in the girl’s hostels. The study estimated the daily waste generation from girl’s hostels and found waste generation rate was high but the waste collection rate was very low because of the improper ratio between the total number of students and sanitary worker. The waste management system in the university girl’s hostels requires not only an estimation of the solid waste but also an understanding of the students’ habits and behaviour towards managing solid waste.

The memory has a narrative structure. Recovering the epistemological approaches of the collective memory of Halbwachs, Blondel, Bartlett and Vygotskij, and reflecting on Bruner's postulates on narrative thought, the present study supports the perspective of collective memory constituted by narratives in autobiographical and dialogical form that They allow the narrative rereading of experiences (understood as focal events by the subject), culturally endowed with meaning by the individual and by the community. Undoubtedly, on a daily basis we are surrounded by a sea of narratives (Bruner, 1992), which intersect and become contaminated with others, defining the limits of common experiences that the community represents the memories of a past endowed with a renewed sense exchange and co-constructed for each unique autobiography. Therefore, we could say that narratives become social structures of memory, such as time and space (Halbwachs, 1987), and they need recreations to be renewed and guarded in the collective memory, so as not to lose their meaning by being enveloped by the dust of old memories and old drawers. This work describes a creative writing workshop with the Digital Storytelling methodology with a group of twenty students from the Geography course at the University of Bologna who have been asked to tell a story in the first person to describe a representative place for them, the place of memories or a place where a focal event in your personal history occurred. The pedagogical purpose of the laboratory resides in the active and reconstructive function of the account of the experience, which is not limited only to the storage of places and events, but also to the work of reflection and discovery of the self, it has underlined how the autobiographical account can offer an interpretation of meaning jointly to the stories of the members of a community, in other words, the exchange of memories and with them, an interpretation of past events would facilitate recognition in a common history while maintaining a collective identity through values, beliefs and myths that the same collective memory transmits and builds.

John Rae, a Scottish antiquarian collector and spirit merchant, played a highly prominent role in the local natural history societies and exhibitions of nineteenth-century Aberdeen. While he modestly described his collection of archaeological lithics and other artefacts, principally drawn from Aberdeenshire but including some items from as far afield as the United States, as a mere ‘routh o’ auld nick-nackets' (abundance of old knick-knacks), a contemporary singled it out as ‘the best known in private hands' (Daily Free Press 4/5/91). After Rae's death, Glasgow Museums, National Museums Scotland, the University of Aberdeen Museum and the Pitt Rivers Museum in Oxford, as well as numerous individual private collectors, purchased items from the collection. Making use of historical and archive materials to explore the individual biography of Rae and his collection, this article examines how Rae's collecting and other antiquarian activities represent and mirror wider developments in both the ‘amateur’ antiquarianism carried out by Rae and his fellow collectors for reasons of self-improvement and moral education, and the ‘professional’ antiquarianism of the museums which purchased his artefacts. Considered in its wider nineteenth-century context, this is a representative case study of the early development of archaeology in the wider intellectual, scientific and social context of the era.

The proposed material examines the creative task of students majoring in Social Pedagogy at the University „Prof. Dr. Assen Zlatarov“ in Burgas, and studying the discipline Art Pedagogy – Part 1 – Music. In the course of the lecture course students get acquainted with the elements of musical expression, as a means of figurative representations and impact of music, with different techniques concerning individual musical activities, with the endless and diverse opportunities that music provides in the use of art pedagogy for social work teachers.Verbal interpretation of music is a necessary component when working with children with special educational needs, at risk and in the norm. Looking at Tchaikovsky’s short and extremely figurative piano piece „The Sick Doll“ from his charming „Children’s Album“, in the form of a short story, tale or essay, students express their personal vision, feeling and transformation of the musical image. The aim of the task is to transcribe the sound image into a verbal one. This requires speed, flexibility and logic in thinking, through imagination and creativity in its manifestation. Children love to listen, especially when they are involved. In search of the right way to solve problems and situations, future social educators could successfully benefit from the conversion of sound into words, according to the needs and deficits of the individual or group.

Universities have a crucial role in the modern world. In England, entrance to universities is by nation-wide competition which means English universities have an exceptional influence on schools--a striking theme of the book. This important book first investigates the university as an institution and then tracks the individual on their journey to and through university. In A University Education, David Willetts presents a compelling case for the ongoing importance of the university, both as one of the great institutions of modern society and as a transformational experience for the individual. The book also makes illuminating comparisons with higher education in other countries, especially the US and Germany. Drawing on his experience as UK Minister for Universities and Science from 2010 to 2014, the author offers a powerful account of the value of higher education and the case for more expansion. He covers controversial issues in which he was involved from access for disadvantaged students to the introduction of L9,000 fees. The final section addresses some of the big questions for the future, such as the the relationship between universities and business, especially in promoting innovation.. He argues that the two great contemporary trends of globalisation and technological innovation will both change the university significantly. This is an authoritative account of English universities setting them for the first time in their new legal and regulatory framework.

Abstract Our objective is to study Canada’s patenting activity over time in aggregate terms by destination country, by assignee and destination country, and by diversification by country of destination. We collect bibliographic patent data from the Canadian Intellectual Property Office and the United States Patent and Trademark Office. We identify 19,957 matched Canada–US patents, 34,032 Canada-only patents, and 43,656 US-only patents from 1980 to 2014. Telecommunications dominates in terms of International Patent Classification technologies for US-only and Canada–US patents. At the firm level, the greatest number of matched Canada–US patents were granted in the field of telecommunications, at the university level in pharmaceuticals, at the government level in control and instrumentation technology, and at the individual level in civil engineering. We use entropy to quantify technological diversification and find that diversification indices decline over time for Canada and the USA; however, all US indices decline at a faster rate.

Chairman Bloomer: In leading this round table I have with me Dr. Charles Strother, Professor of Clinical Psychology in the College of Medicine of the University of Washington at Seattle. I am from the University of Michigan Speech Clinic in Ann Arbor. We are very glad to be with you at this round table because it suggests the close relationship between the fields of speech pathology and pediatrics. We come to the American Academy of Pediatrics as representatives of the American Speech and Hearing Association which is the national organization for professional people interested in the study of speech disorders, their causes and their methods of treatment. Perhaps you are familiar with the official publication of the Association, the Journal of Speech and Hearing Disorders. We bring you greetings from the Association. I think you may be interested in a brief outline of our general plan of discussion for the afternoon. The first part of our discussion will review the importance of a knowledge of speech disorders to specialists in pediatrics. Next we shall discuss in some detail the nature of these disorders and the etiologic factors which are frequently encountered, and then we shall suggest methods for handling the speech problems which the individual child may present. We shall be glad to have your participation, your questions, and your comments at any time during our discussion. We feel that this subject is particularly timely because of the steadily increasing interest of pediatricians in the general aspects of child growth and development rather than in only the medical care of children.

Purpose The purpose of this review article is to examine the well-being of faculty in higher education. Success in academia depends on productivity in research, teaching, and service to the university, and the workload model that excludes attention to the welfare of faculty members themselves contributes to stress and burnout. Importantly, student success and well-being is influenced largely by their faculty members, whose ability to inspire and lead depends on their own well-being. This review article underscores the importance of attending to the well-being of the people behind the productivity in higher education. Method This study is a narrative review of the literature about faculty well-being in higher education. The history of well-being in the workplace and academia, concepts of stress and well-being in higher education faculty, and evidence-based strategies to promote and cultivate faculty well-being were explored in the literature using electronic sources. Conclusions Faculty feel overburdened and pressured to work constantly to meet the demands of academia, and they strive for work–life balance. Faculty report stress and burnout related to excessively high expectations, financial pressures to obtain research funding, limited time to manage their workload, and a belief that individual progress is never sufficient. Faculty well-being is important for the individual and in support of scholarship and student outcomes. This article concludes with strategies to improve faculty well-being that incorporate an intentional focus on faculty members themselves, prioritize a community of well-being, and implement continuous high-quality professional learning.

The pathogenesis of acne vulgaris has only been partially elucidated. Various hormones, especially androgens, are likely to play a role, but results of studies are still inconclusive. The objective of the current study was to investigate whether day to day variation in salivary testosterone correlates with acne in males. Saliva samples were collected for 120 consecutive days from each of the 40 males. Salivary testosterone concentrations were measured by enzyme-linked immunosorbent assay (ELISA). Facial acne lesions were assessed on a daily basis by photography by the participating males. Potential confounders’ (sexual intercourse, masturbation, physical exercise and disease) were also registered every day by the participants. A significant but weak association between salivary testosterone and acne was found (n = 4602, r = 0.031, P = 0.034). Elevated testosterone concentrations were associated with an increase in acne, but when testosterone concentrations were above twice the individual average, acne lesions paradoxically decreased. The current results indicate that daily fluctuations in salivary testosterone levels in males are associated with acne patterns, but the weak correlation suggests that the effect is too small to be of clinical significance. The analysis in the current study was complicated by a large number of days on which the participants had no acne, as well as the seemingly non-monotonic relation between testosterone and acne. This may indicate that the actual relation is stronger than concluded here.
