Physical activity (PA) is increasingly considered an important public health issue and as such requires the development of good public health policy. This paper provides a summary of the literature on policy development and defines what a policy on PA may usefully comprise. The results of an international review of national level PA policies, using a defined set of criteria, are reported. Considerable similarities were found in the methods and approaches to policy development on PA across countries, with most adopting an intersectoral approach, with consultation and partnership between sectors occurring at a high level of government. The need for action across the lifespan is recognised, as is the need for multiple strategies across a variety of settings. A review of Australian PA policy found that, after promising strategic developments through Active Australia in the late 1990s, PA policy and the role of the federal health sector has become less clear, with PA policy existing now only as a component part integrated into other chronic disease prevention policy initiatives. Recommendations towards better practice in policy making are made with particular reference to developing a clearly defined integrated national PA policy in the Australian context.

The law of contract can be a complex and technical subject, rvt the new edition of Jill Poole's Casebook on Contract provides a clear and well-structured exposition of the principles and rules through a comprehensive selection of case law, addressing all aspects encountered on undergraduate courses. Opening with a chapter of valuable advice and guidance on how to successfully develop and improve the essential skills of case-reading, featuring two worked examples, the coverage in this sixth edition expands to incorporate all recent significant decisions and judgments made by the House of Lords and Court of Appeal such as, Director General of Fair Trading v First National Bank plc, Farley v Skinner, Royal Bank of Scotland v Etridge and UCB Corporate Services v Williams. Interesting recent decisions in relation to battle of forms, terms, exemption clauses and misrepresentation are also included. Extracts have been chosen from a wide range of historical and contemporary cases to illustrate the reasoning processes of the court, why decisions are made and how legal principles are developed - enabling cases to be analysed and discussed independently while, taken as a whole, the chapters provide a sound understanding of the modern law of contract. The section on damages for breach of contract has been expanded to reassess Ruxley Electronics and Construction Ltd v Forsyth in the light of Farley v Skinner, the future of Addis v Gramophone Co Ltd is considered in the light of Johnson v Unisys Ltd and Attorney General v Blake is examined in the light of the decision in Esso Petroleum Co Ltd v Niad Ltd. Succinct author comment focuses the reader on the key elements within the extracts, while thought-provoking questions are posed throughout to develop more in-depth analysis. The logical and clear organization of topics has been further improved to more accurately echo the order adopted within the author's popular textbook and closer crossreferencing to this text has been incorporated to highlight where more detailed discussion of issues arising from the caselaw can be explored. As a result, this new edition can be used both as a traditional casebook and as a companion volume to Poole's Textbook on Contract. This edition is also supported by a new companion web site that offers the benefits of essential updating of key materials, sample questions, lists for key further reading sources and relevant web links, additional relevant cases and materials and guidance on successful exam technique. As with previous editions, Casebook on Contract is an invaluable primary source and an essential study aid for all those following elements of contract law as part of the LLB and CPE, as well as for students from related disciplines such as Accounting and Business.

PURPOSE: To evaluate factors affecting corneoscleral profile (CSP) using Anterior Segment Optical Coherence Tomography (AS-OCT) in combination with conventional videokeratoscopy. METHODS: OCT data were collected from 204 subjects of mean age 34.9 years (SD: ±15.2 yrs, range 18 to 65) using the Zeiss Visante AS-OCT and Medmont M300 corneal topographer. Measurements of corneal diameter (CD), corneal sagittal height (CS), iris diameter (ID), corneoscleral junction angle (CSJ) and scleral radius (SR) were extracted from multiple OCT images. Horizontal visible iris diameter (HVID) and vertical palpebral aperture (PA) were measured using a slit lamp graticule. Subject body height was also measured. Associations were then sought between CSP variables and age, height, ethnicity, sex and refractive error data collected. Results: Significant correlations were found between age and ocular topography variables of HVID, PA, CSJ, SR and ID (P<0.0001), while height correlated with HVID, CD and ID, and power vector terms only with vertical plane keratometry, CD and CS. Significant differences were noted between ethnicities with respect to CD (P=0.0046), horizontal and vertical CS (P=0.0068 and P=0.0095), and also horizontal ID (P=0.0010), while the same variables, with the exception of vertical CS, also varied with sex; horizontal CD (P=0.0018), horizontal CS (P=0.0018) and ID (P=0.0012). Age accounted for up to 36% of the variance in CSP variables. Conclusion: Age is the main factor influencing corneoscleral topography; consequently, this should be taken into consideration in contact lens design, in the optimization of surgical procedures involving the cornea and sclera and in IOL selection.

This dissertation explores the role of artillery forward observation teams during the battle of Okinawa (April–June 1945). It addresses a variety of questions associated with this front line artillery support. First, it examines the role of artillery itself in the American victory over the Japanese on Okinawa. Second, it traces the history of the forward observer in the three decades before the end of World War II. Third, it defines the specific role of the forward observation teams during the battle: what they did and how they did it during this three-month duel. Fourth, it deals with the particular problems of the forward observer. These included coordination with the local infantry commander, adjusting to the periodic rotation between the front lines and the artillery battery behind the line of battle, responding to occasional problems with "friendly fire" (American artillery falling on American ground forces), dealing with personnel turnover in the teams (due to death, wounds, and illness), and finally, developing a more informal relationship between officers and enlisted men to accommodate the reality of this recently created combat assignment. Fifth, it explores the experiences of a select group of men who served on (or in proximity to) forward observation teams on Okinawa. Previous scholars and popular historians of the battle have emphasized the role of Marines, infantrymen, and flame-throwing armor. This work offers a different perspective on the battle and it uses new sources as well. A pre-existing archive of interviews with Okinawan campaign forward observer team members conducted in the 1990s forms the core of the oral history component of this research project. The verbal accounts were checked against and supplemented by a review of unit reports obtained from the U.S. National Archives and various secondary sources. The dissertation concludes that an understanding of American artillery observation is critical to a more complete comprehension of the battle of Okinawa. These mid-ranking (and largely middle class) soldiers proved capable of adjusting to the demands of combat conditions. They provide a unique and understudied perspective of the entire battle.

This thesis studies the historic encounter between United States Navy airship K-74 and Nazi submarine U-134 in World War II. The Battle of the Atlantic is examined through case study of this one U-boat and its voyage. In all things except her fight with the American blimp, the patrol was perfectly typical. Looked at from start to finish, both her reports and the reports of the Allies encountered, many realities of the war can be studied. U-134 sailed to attack shipping between Florida and Cuba. She was challenged by the attack of United States Navy airship K-74 over the Florida Straits. It is the only documented instance of battle between two such combatants in history. That merits attention. Thesis finding disprove historian William Eliot Morison’s contention that the K-74 airship bombs were not dropped and did not damage the U-boat. Study of this U-boat and its antagonist broadens our understanding of the Battle of the Atlantic. It is a contribution to our knowledge of military, naval, aviation, and local history.

This dissertation interrogates existing scholarly paradigms regarding aetiology in the Histories of Herodotus in order to open up new avenues to approach a complex and varied topic. Since aetiology has mostly been treated as the study of cause and effect in the Histories, this work expands the purview of aetiology to include Herodotus’ explanations of origins more generally. The overarching goal in examining the methodological principles of Herodotean aetiology is to show the extent to which they resonate across the Histories according to their initial development in the proem, especially in those places that seem to deviate from the work’s driving force (i.e. the Persian Wars). Though the focus is on correlating the principles espoused in the proem with their deployment in Herodotus’ ethnographies and other seemingly divergent portions of his work, the dissertation also demonstrates the influence of these principles on some of the more “historical” aspects of the Histories where the struggle between Greeks and barbarians is concerned. The upshot is to make a novel case not only for the programmatic significance of the proem, but also for the cohesion of Herodotean methodology from cover to cover, a perennial concern for scholars of Greek history and historiography.

Chapter One illustrates how the proem to the Histories (1.1.0-1.5.3) prefigures Herodotus’ engagement with aetiological discussions throughout the Histories. Chapter Two indicates how the reading of the proem laid out in Chapter One allows for Herodotus’ deployment of aetiology in the Egyptian logos (especially where the pharaoh Psammetichus’ investigation of the origins of Egyptian language, nature, and custom are concerned) to be viewed within the methodological continuum of the Histories at large. Chapter Three connects Herodotus’ programmatic interest in the origins of erga (i.e. “works” or “achievements” manifested as monuments and deeds of abstract and concrete sorts) with the patterns addressed in Chapters One and Two. Chapter Four examines aetiological narratives in the Scythian logos and argues through them that this logos is as integral to the Histories as the analogous Egyptian logos studied in Chapter Two. Chapter Five demonstrates how the aetiologies associated with the Greeks’ collaboration with the Persians (i.e. medism) in the lead-up to the battle of Thermopylae recapitulate programmatic patterns isolated in previous chapters and thereby extend the methodological continuum of the Histories beyond the “ethnographic” logoi to some of the most representative “historical” logoi of Herodotus’ work. Chapter Six concludes the dissertation and makes one final case for methodological cohesion by showing the inextricability of the end of the Histories from its beginning.

De acuerdo a lo que se ha dado en llamar "historia del sentido" (Assmann, 2005), cada sociedad posee una forma cultural que le es inherente y es precisamente en ella donde adquieren sentido los acontecimientos y procesos históricos, comprensibles sólo a través de los discursos producidos. Los relieves y las inscripciones de la Batalla de Kadesh, durante el reinado de Ramsés II (1279-1213 a.C.) constituyen un claro ejemplo de rememoración y manifestación de esos discursos. En este trabajo, nos proponemos analizarlos como ejemplos de procesos constructivos de la "memoria cultural" (Assmann, 2008), tomando como categorías de análisis los postulados de la semiótica de Umberto Eco (1994 (1973); 2013 (1968)) y del análisis de la imagen de Martine Joly (2012 (1993)). Como premisa básica, consideraremos a los relieves y las inscripciones que los acompañaban como una unidad total narrativa, como discursos que se completan y complementan, para ser eficaces.

CO2 emissions are leading to an acidification of the oceans. Predicting marine community vulnerability towards acidification is difficult, as adaptation processes cannot be accounted for in most experimental studies. Naturally CO2 enriched sites thus can serve as valuable proxies for future changes in community structure. Here we describe a natural analogue site in the Western Baltic Sea. Seawater pCO2 in Kiel Fjord is elevated for large parts of the year due to upwelling of CO2 rich waters. Peak pCO2 values of >230 Pa (>2300 µatm) and pHNBS values of <7.5 are encountered during summer and autumn, average pCO2 values are ~70 Pa (~700 µatm). In contrast to previously described naturally CO2 enriched sites that have suggested a progressive displacement of calcifying auto- and heterotrophic species, the macrobenthic community in Kiel Fjord is dominated by calcifying invertebrates. We show that blue mussels from Kiel Fjord can maintain control rates of somatic and shell growth at a pCO2 of 142 Pa (1400 µatm, pHNBS = 7.7). Juvenile mussel recruitment peaks during the summer months, when high water pCO2 values of ~100 Pa (~1000 µatm) prevail. Our findings indicate that calcifying keystone species may be able to cope with surface ocean pHNBS values projected for the end of this century when food supply is sufficient. However, owing to non-linear synergistic effects of future acidification and upwelling of corrosive water, peak seawater pCO2 in Kiel Fjord and many other productive estuarine habitats could increase to values >400 Pa (>4000 µatm). These changes will most likely affect calcification and recruitment, and increase external shell dissolution.
