A wide range of longlasting patterns of symptoms may result from individual sensitivity to substances in the environment such as foods, chemicals, dusts and pollens. Behaviourally disturbed and learning disordered children are common. Their numbers may be increasing and certainly they make great demands on parental understanding and courage as well as on professional judgement and time. A number of case studies are presented which suggest that the difficulties encountered by a significant number of these children have much to do with idiosyncratic responses to foods and additives. This hypothesis requires careful research study at an early date for if validated it will have far reaching implications for the assessment and management of disturbed, delinquent and learning disordered children. Perhaps not enough attention has been paid to the role of biological and environmental factors in the development of children's problems. Certainly recent research has begun to provide support for the concept of environmental (ecologic) illness.

Modern research on the sustainability of the urban environment mainly focuses on environmental factors like water, air, energy and transport, while urban identity rarely attracts attention. The concept of sustainability, which includes the identity of the urban environment, combines a wide range of factors, including urban planning and architectural objects, natural, geographical, cultural products and social norms. With modern architectural and urban development and globalization, cities are increasingly facing the problem of losing their original identity. In the context of the concept of the identity of the urban environment considered in this study, the role of urban planning objects, architecture and culture in the formation and maintenance of the unique identity of the city of Astrakhan and the need for considerable attention to the resource of identity for the development of the city and the region is stressed.

Since Flinders Petrie, the importance of Western Asia to the history and development of culture in ancient Egypt has been recognized by scholars and has also been a significant driver in shaping Egyptological methodology and theoretical approaches. The study of relations between Western Asia and Egypt encompasses a wide range of specialisms given the broad range of evidence, the geographical breadth, and the academic disciplines involved. This chapter reviews the history of the study of relations between Western Asia and Egypt pointing to a selection of challenges scholars face in undertaking their research, and examines two case studies: theories concerning the role of Western Asia in the rise of the state, and the assessment of Egypt’s New Kingdom Empire in Canaan to illustrate the ways in which scholarly challenges are met and the resulting historical conclusions.

The state of the planet calls for large-scale sustainability transitions involving systemic adoption of markedly better environmental and social practices. The objective of this symposium is to better understand the role of corporations in promoting such systemic change. We present four case studies—representing diverse industries and change mechanisms—-to investigate corporate leadership in sustainability transitions. The cases examine a wide range of mechanisms used by corporations to progress toward sustainability, such as political coalition building and information strategies through eco-labels, socially responsible investing, and the public statements of CEOs. In this introduction, we discuss the challenges associated with both achieving and studying systemic change, explain the rationale for a case study approach, describe the findings from the case studies, and draw some general conclusions on the mechanisms by which firms may be able to lead, or at least participate in, systemic change in the different phases of sustainability transitions.

AbstractThis article examines the role of particular ideas of the countryside in unemployment relief schemes. While interwar thinking on the countryside has received attention, it has not been examined in the specific context of unemployment relief. This article uses four case studies from North East England, namely the Team Valley Trading Estate (Gateshead), Hamsterley Forest Instructional Centre (Durham), Swarland model village (Northumberland) and Heartbreak Hill (Cleveland). All four projects took different approaches to the unemployment problem, but all used some form of rural rhetoric. The ways in which the projects deployed images of the countryside creatively recombined a wide range of ideas to suit their needs rather than being rigidly confined by particular schools of thought.

This research study set to develop KPIs for airport safety and security using a case study and ethnographic approach to research, the focus was on the role of Facilities Management (FM) in improving safety and security at the airport. The study centred on the management and staff of the case study airport and experts in the field of facilities management and aviation. The methodology for this study is a case study of three Scottish airports, owned and operated by the BAA Scotland (Glasgow, Edinburgh and Aberdeen international airports). Data was collected from Civil Aviation Agency, analysed and presented in the study. The study developed a three ‘AAA’ model (Airport – Aircraft – Airport) and a 3 stage approach to the research process. Evidence in this paper supports the conclusion that planning for airport safety and security are airport specific because no two airports are exactly the same, they differ in their; sizes, mode of operations, passenger type and flight destinations. Santruka Šiuo tyrimu siekta sukurti oro uosto sauguma ir apsauga užtikrinančius pagrindinius veiklos rodiklius (KPI), pasitelkus atvejo tyrima ir etnografini požiūri i tyrima. Daugiausia demesio skirta pastatu ūkio valdymo reikšmei, didinant oro uosto sauguma ir apsauga. Tyrimo centre ‐ atvejui tirti pasirinktu oro uostu vadovai ir darbuotojai bei pastatu ūkio valdymo ir aviacijos sričiu ekspertai. Šiam tyrimui pasirinkta metodika ‐ tai triju Škotijos oro uostu, priklausančiu ir valdomu BAA Scotland (Glazgo, Edinburgo ir Aberdyno tarptautiniai oro uostai), atvejo tyrimas. Iš Civilines aviacijos agentūros surinkti duomenys buvo išanalizuoti ir yra pateikiami tyrime. Tyrimo metu sukurtas triju O modelis (oro uostas – orlaivis – oro uostas; angl. Airport‐Aircraft‐Airport, t. y. triju A modelis) ir trižingsnis požiūris i tyrimo procesa. Iš šiame darbe pateiktu irodymu kyla išvada, kad kiekvienas oro uostas sauguma ir apsauga planuos kitaip, nes nera dvieju visiškai vienodu oro uostu: skiriasi ju dydis, valdymo būdas, keleiviai ir skrydžiu paskirties punktai.

The prevalence of obesity is increasing worldwide at an alarming rate in both developed and developing countries. Obesity is a chronic complex disease of multifactorial origin resulting from a long-term positive energy balance, in which both genetic and environmental factors are involved. Genetically prone individuals are the first to accumulate fat in the present obesogenic environment. Obesity increases the risks of type 2 diabetes, hypertension, cardiovascular disease, dyslipidemia, arthritis, and several cancers and reduces the average life expectancy. Implementation of effective strategies in prevention and management of obesity should become an important target in health care systems. Weight changes throughout life depend on the interaction of behavioral, genetic and environmental factors. Weight loss in response to weight management shows a wide range of interindividual variation which is largely influenced by genetic determinants. The strong control of weight loss by genotype was confirmed by twin and family studies. Recently, special attention has been paid to nutritional, hormonal, psychobehavioral and genetic factors which can predict the response to weight reduction programme. In this article currently available data on the role of obesity candidate gene polymorphisms in weight loss and maintenance are reviewed. It is believed that an elucidation of the genetic component in the prognosis of weight management could assist in the development of more effective and individually tailored therapeutic strategies.

<p>This doctoral thesis is an examination of the relationship between poetry and mathematics, centred on three twentieth-century case studies: the Polish poets Czesław Miłosz (1911-2004) and Zbigniew Herbert (1924-1998), and the Romanian mathematician and poet Dan Barbilian/Ion Barbu (1895-1961).  Part One of the thesis is a review of current scholarly literature, divided into two chapters. The first chapter looks at the nature of mathematics, outlining its historical developments and describing some major mathematical concepts as they pertain to the later case studies. This entails a focus on non-Euclidean geometries, modern algebra, and the foundations of mathematics in Europe; the nature of mathematical truth and language; and the modern historical evolution of mathematical schools in Poland and Romania. The second chapter examines some existing attempts to bring together mathematics and poetry, drawing on literature and science as an academic field; the role of the imagination and invention in the languages of both poetics and mathematics; the interest in mathematics among certain Symbolist poets, notably Mallarmé; and the experimental work of the French groups of mathematicians and mathematician-poets, Bourbaki and Oulipo. The role of metaphor is examined in particular.  Part Two of the thesis is the case studies. The first presents the ethical and moral stance of Czesław Miłosz, investigating his attitudes towards classical and later relativistic science, in the light of the Nazi occupation and the Marxist regimes in Poland, and how these are reflected in his poetry. The study of Zbigniew Herbert is structured around a wide selection of his poetic oeuvre, and identifying his treatment of evolving and increasingly more complex mathematical concepts. The third case study, on Dan Barbilian, who published his poetry under the name Ion Barbu, begins with an examination of the mathematical school at Göttingen in the 1920s, tracing the influence of Gauss, Riemann, Klein, Hilbert and Noether in Barbilian’s own mathematical work, particularly in the areas of metric spaces and axiomatic geometry. In the discussion, the critical analysis of the mathematician and linguist Solomon Marcus is examined. This study finishes with a close reading of seven of Barbu’s poems.  The relationship of mathematics and poetry has rarely been studied as a coherent academic field, and the relevant scholarship is often disconnected. A feature of this thesis is that it brings together a wide range of scholarly literature and discussion. Although primarily in English, a considerable amount of the academic literature collated here is in French, Romanian, Polish and some German. The poems themselves are presented in the original Polish and Romanian with both published and working translations appended in the footnotes. In the case of the two Polish poets, one a Nobel laureate and the other a multiple prize-winning figure highly regarded in Poland, this thesis is unusual in its concentration on mathematics as a feature of the poetry which is otherwise much-admired for its politically-engaged and lyrical qualities. In the case of the Romanian, Dan Barbilian, he is widely known in Romania as a mathematician, and most particularly as the published poet Ion Barbu, yet his work is little studied outside that country, and indeed much of it is not yet translated into English.  This thesis suggests at an array of both theoretical and specific starting points for examining the multi-stranded and intricate relationship between mathematics and poetry, pointing to a number of continuing avenues of further research.</p>

Abstract This article explores the role of public engagement by select committees of the House of Commons. It shows that committees’ public engagement activity has been transformed since 1979, when departmental select committees were introduced. We start by outlining the different elements of public engagement, showing that it entails a wide range of types of activity from information about committees’ activity to opportunities through which citizens can shape parliamentary decisions. We then proceed to outline how public engagement has become a core activity of select committees in the House of Commons. We show developments taking place within all elements of public engagement. Through the use of case studies, we illustrate specific innovations that have led towards more agile and inclusive ways to consult and involve the public into committees’ activities. We finish by identifying some of the challenges still present, namely the need to reach new and more varied audiences.

<p>The introduction of non-indigenous species and environmental changes are both important threats to marine ecosystems. Environmental changes occur simultaneously and might impact marine organisms synergically or antagonistly. The success of invasive species has been attributed in part to their greater capacity to acclimate to changing conditions. However, the effect of environmental factors on marine invasive species has been little studied. This thesis studied the tolerance of different life stages of the invasive brown seaweed Undaria pinnatifida to UVB and temperature. Also, the possible interactive effect of an increase of temperature and UVB on U. pinnatifida was evaluated.  The tolerance of motile zoospores U. pinnatifida to increasing UVB irradiances was studied in laboratory experiments, and a strong negative effect of UVB on motile zoospores of U. pinnatifida was observed. However, zoospores can recover from UVB stress and the degree of recovery depended on UVB irradiances and exposure time. Their ability to recover could increase the opportunity of zoospores to survive and succeed in the invasion process and shows that U. pinnatifida can survive after UVB stress when environmental conditions improve.  The effect of light treatments combined with temperature was also investigated in early life stages of U. pinnatifida. Both treatments affected early life stages independently. Early life stages were particularly sensitive to UVB; more so than the other light treatments and temperature. The tolerance of early life stages to a wide range of light and temperature conditions might allow this species to maintain viable populations where they already exist, but also might permit it to invade other areas if predicted environmental changes occur in the future.  The effect of consecutive exposures to PAR and UV treatments at different temperatures on sporophytes of U. pinnatifida and the possible photoprotective role of phlorotannins were investigated. There was an interactive effect of light treatments, temperature during the exposure of sporophytes. Sporophytes were highly sensitive to UVB but not to the other light treatments nor to an increase of water temperature. There was no evidence of induction of phlorotannins by UVB and the other light treatments in U. pinnatifida. The sensitivity of sporophytes of U. pinnatifida to UVB and the lack of photoprotective role of phlorotannins suggests this species might have other strategies for success in the intertidal and might direct its energy mainly to growth and reproduction rather than to photoprotection and repair.  The response of the photosynthetic capacity and phlorotannins content to seasonal variations of light and UVB of U. pinnatifida was investigated. A clear seasonal trend in the photosynthetic capacity was observed in sporophytes that were correlated to PAR and UVB irradiances measured in the field. Phlorotannins were variable throughout the sampling period where soluble phlorotannins had seasonal and interannual variation, while there was no clear seasonal variation in cell wall phlorotannins concentration. No correlation between both phlorotannins and PAR and UVB was detected. The response of the photosynthetic apparatus to variations of light illustrates the capacity of this species to acclimate to ambient light conditions. Variation of phlorotannins throughout the year could be attributed to a combination of factors such as grazer and wound healing rather than only to the light conditions.  This research contributed to a better understanding of the tolerance of U. pinnatifida to environmental factors. This study showed that the tolerance and response to environmental factors is life stage specific. The major factor affecting U. pinnatifida negatively was UVB, while temperature had little impact on this species. The capacity of U. pinnatifida to inhabit a wide range of light and temperature conditions permits this species to succeed in coastal ecosystems, and these characteristics could permit this species to succeed under future climate change scenarios.</p>
