    This is the author accepted manuscript. The final version is available from the publisher via the DOI in this recordDespite growing recognition of the global value of underwater cultural heritage (UCH), along with intensified international efforts to ensure its protection, the possibility of its inscription on the World Heritage List has never been comprehensively examined. Arguing that the UNESCO 2001 Convention on the Protection of Underwater Cultural Heritage (UCH Convention) is not sufficient alone to protect globally outstanding wrecks, such as the Titanic and the Lusitania, this article examines in detail the many legal and practical challenges involved with listing such sites under the World Heritage Convention. By reviewing key international agreements such as the UCH Convention, World Heritage Convention, Law of the Sea Convention and the International Titanic Agreement, it draws the conclusion that it is the improved offshore management of UCH - through 'cultural' marine protected areas operating under the framework of the UCH Convention - which would open the possibility of nomination to the World Heritage List

    This is the author accepted manuscript. The final version is available from the publisher via the link in this recordDesigning an online arbitration procedure which delivers the cornerstone requirements of efficiency, value and fairness has been described as the ‘grail quest’ for online dispute resolution (ODR). Focusing on the incipient global legal framework for both business-to-consumer (B2C) and business-to-business (B2B) arbitration, this paper explores whether current due process or consumer protection laws might be preventing the creation of an international system of binding low-value online ODR. Intending to stimulate innovation in this nascent industry, evaluation is made of the unsuccessful efforts to develop a transnational online arbitration model at the United Nations Commission on Trade Law, the newly launched European Union online dispute resolution platform, and the extant Uniform Domain Name Dispute Resolution Policy. Through comparison of EU and US approaches to mandatory consumer arbitration clauses, it questions whether such clauses would need to become enforceable ex ante before an international consumer arbitration system can ever be fully fledged. It also explores the minimum procedural requirements for low-value B2B and B2C arbitration and, as such, may be of great interest to dispute resolution entrepreneurs, professionals and regulators wishing to capitalise on the growing millions of high-volume low-value cross-border legal claims not being internally managed by online intermediaries or service providers. By reviewing various developments in the industry, such as fast-track arbitration and consumer ODR systems, it will attempt to resolve the ever-present dilemma of maintaining each fairness and efficiency within an affordable and expedient online arbitration process. Naturally, therefore, various elements of online arbitration procedural design are closely examined, appraising matters such as documents-only hearings, fees & funding, document disclosure, time limits, transparency, award reasoning and applicable law

    Inference of riverine nitrogen processing from longitudinal and diel variation in dual nitrate isotopes

    Longitudinal and diel measurements of dual isotope composition (δ<sup>15</sup>N and δ<sup>18</sup>O) in nitrate (NO<inf>3</inf>-N) were made in the Ichetucknee River, a large (∼8m<sup>3</sup> s <sup>-1</sup>), entirely spring-fed river in North Florida, to determine whether isotopic variation can deconvolve assimilatory and dissimilatory removal. Comparing nitrate concentrations and isotope composition during the day and night we predicted (1) daytime declines in total fractionation due to low assimilatory fractionation and (2) diurnal variation in dual isotope coupling between 1:1 (assimilation) and 2:1 (denitrification). Five daytime longitudinal transects comprising 10 sampling stations showed consistent NO<inf>3</inf>-N removal (25-35% of inputs) and modest fractionation (<sup>15</sup>ε <inf>total</inf> between -2 and -6‰, enriching the residual nitrate pool). Lower fractionation (by ∼1‰) during two nighttime transects, suggests higher fractionation due to assimilation than denitrification. Total fractionation was significantly negatively associated with discharge, input [NO<inf>3</inf>-N], N mass removal, and fractional water loss. Despite well-constrained mass balance estimates that denitrification dominated total N removal, isotope coupling was consistently 1:1, both for longitudinal and diel sampling. Hourly samples on two dates at the downstream location showed significant diel variation in concentration ([NO<inf>3</inf>-N] amplitude = 60 to 90 μg N L<sup>-1</sup>) and isotope composition (δ<sup>15</sup>N amplitude = -0.7‰ to -1.6‰). Total fractionation differed between day and night only on one date but estimated assimilatory fractionation assuming constant denitrification was highly variable and implausibly large (for N, <sup>15</sup>ε = -2 to -25‰), suggesting that fractionation and removal due to denitrification is not diurnally constant. Pronounced counterclockwise hysteresis in the relationship between [NO<inf>3</inf>-N] and δ<sup>15</sup>N suggests diel variation in N isotope dynamics. Together, low fractionation, isotope versus concentration hysteresis, and consistent 1:1 isotope coupling suggests that denitrification is controlled by NO <inf>3</inf><sup>-</sup> diffusion into the benthic sediments, the length of which is mediated by riverine oxygen dynamics. While using dual isotope behavior to deconvolve removal pathways was not possible, isotope measurements did yield valuable information about riverine N cycling and transformations.

    Weaknesses in the Law Protecting the United Kingdom’s Remarkable Underwater Cultural Heritage: The Need for Modernisation and Reform

    Get PDF
    This is the final version. Available on open access from Spriner Verlag via the DOI in this recordDespite the United Kingdom (UK) having been regarded as one of the richest hotspots for underwater cultural heritage (UCH), its policy and practice regarding its protection has displayed some areas of weakness. This paper makes a case to review the legal framework and its overall administration in the UK, in order to protect and preserve any remaining UCH before it is further lost or damaged. First, we introduce some of the flaws in the UK’s legal system protecting UCH, demonstrating how it has led to a considerable loss of cultural heritage and underlining how it is in need of modernisation. This includes discussion of issues raised in a number of recent cases, including the proposed Victory (1744) recovery project, the proposed Goodwin Sands dredging licence and various cases relating to the illegal recovery of material. We then map out how policy is implemented in practice and the role played by various institutions involved with its administration, where we find a schism between what policy intends and what it is achieving in practice. This takes us towards a broader discussion on how legislative reform might look, including a more proactive and ambitious approach to the future management and enjoyment of the UK’s impressive UCH. Here we argue the need for better engagement at the global and regional negotiating table, as well as in favour of adopting a unified and consistent policy which aims to be more sustainable, precautionary, proportionate and inclusive

    Understanding the relationship between loneliness, substance use traits and psychiatric disorders: A genetically informed approach

    Loneliness is a common, yet distressing experience associated with adverse outcomes including substance use problems and psychiatric disorders. To what extent these associations reflect genetic correlations and causal relationships is currently unclear. We applied Genomic Structural Equation Modelling (GSEM) to dissect the genetic architecture between loneliness and psychiatric-behavioural traits. Included were summary statistics from 12 genome-wide association analyses, including loneliness and 11 psychiatric phenotypes (range N: 9,537 – 807,553). We first modelled latent genetic factors amongst the psychiatric traits to then investigate potential causal effects between loneliness and the identified latent factors, using multivariate genome-wide association analyses and bidirectional Mendelian randomization. We identified three latent genetic factors, encompassing neurodevelopmental/mood conditions, substance use traits and disorders with psychotic features. GSEM provided evidence of a unique association between loneliness and the neurodevelopmental/mood conditions latent factor. Mendelian randomization results were suggestive of bidirectional causal effects between loneliness and the neurodevelopmental/mood conditions factor. These results imply that a genetic predisposition to loneliness may elevate the risk of neurodevelopmental/mood conditions, and vice versa. However, results may reflect the difficulty of distiguishing between loneliness and neurodevelopmental/mood conditions, which present in similar ways. We suggest, overall, the importance of addressing loneliness in mental health prevention and policy

    Purpose: To investigate retinal thickness and optic disc parameters by the Retinal Thickness Analyzer (RTA) glaucoma program in older normal subjects and to determine any age effect. Methods: Subjects over 40 years of age without any prior history of eye diseases were recruited. Only subjects completely normal on clinical ophthalmologic examination and on visual field testing by Humphrey Field Analyzer (HFA) using the SITA 24-2 program were included. A total of 74 eyes from 74 subjects with even age distribution over the decades were enrolled and underwent topographic measurements of the posterior pole and of the optic disc by RTA. The `glaucoma full' program in software version 4.11B was applied. Results: Mean patient age was 59.9 +/- 10.3 years with a range from 40 to 80 years. The only parameter intraocular pressure (IOP) correlated with was retinal posterior pole asymmetry (r=0.27, p=0.02). IOP itself increased significantly with age (r=0.341, p=0.003). Mean defect and pattern standard deviation of the HFA did not correlate with any of the retinal or optic disc measurements. Increasing age correlated significantly with some of the morphologic measurements of the RTA: decreasing perifoveal minimum thickness (r=-0.258, p=0.026), increased cup-to-disc area ratio (r=0.302, p=0.016) and increased cup area (r=0.338 p=0.007). Conclusions: An age effect exists for some of the retina and optic disc measurements obtained by the RTA. Copyright (C) 2005 S. Karger AG, Basel

    The present paper deals with a free boundary problem modeling the growth process of necrotic multi-layer tumors. We prove the existence of flat stationary solutions and determine the linearization of our model at such an equilibrium. Finally, we compute the solutions of the stationary linearized problem and comment on bifurcation.Comment: 14 pages, 3 figure

    Maximum-Reward Motion in a Stochastic Environment: The Nonequilibrium Statistical Mechanics Perspective

    Get PDF
    We consider the problem of computing the maximum-reward motion in a reward field in an online setting. We assume that the robot has a limited perception range, and it discovers the reward field on the fly. We analyze the performance of a simple, practical lattice-based algorithm with respect to the perception range. Our main result is that, with very little perception range, the robot can collect as much reward as if it could see the whole reward field, under certain assumptions. Along the way, we establish novel connections between this class of problems and certain fundamental problems of nonequilibrium statistical mechanics . We demonstrate our results in simulation examples
