Tidal Title and the Boundaries of the Bay: The Case of the Submerged High Water Mark

There is no particular policy reason why the same line should be used for both the upland boundary of the jus publicum and the seaward boundary of parcels bounded by the sea. In interpreting the language used in grants of private interests, the ostensible object of the inquiry is to ascertain the parties (particularly the grantor\u27s) intent. Subject only to limitations on the grantor\u27s estate or power to convey, it is that intention which controls the extent of his transfer. On the other hand, in setting the upland boundaries of lands subject to the jus publicum, the courts are essentially making a policy determination, i.e., which lands are subject to what mode of use-allocation, a question of law in which private intentions play no role. Nonetheless, for reasons which seem largely historical, the rule of construction for grants extending to the sea has been held to result in the same boundary line as the line which, by law, defines the upland limits of the jus publicum. In the case of both, the line is the high water line. This article explores judicial resolutions in New York to the question: Where is the high water line

‘Hearts and minds’: association, causation and implication of cognitive impairment in heart failure

The clinical syndrome of heart failure is one of the leading causes of hospitalisation and mortality in older adults. An association between cognitive impairment and heart failure is well described but our understanding of the relationship between the two conditions remains limited. In this review we provide a synthesis of available evidence, focussing on epidemiology, the potential pathogenesis, and treatment implications of cognitive decline in heart failure. Most evidence available relates to heart failure with reduced ejection fraction and the syndromes of chronic cognitive decline or dementia. These conditions are only part of a complex heart failure-cognition paradigm. Associations between cognition and heart failure with preserved ejection fraction and between acute delirium and heart failure also seem evident and where data are available we will discuss these syndromes. Many questions remain unanswered regarding heart failure and cognition. Much of the observational evidence on the association is confounded by study design, comorbidity and insensitive cognitive assessment tools. If a causal link exists, there are several potential pathophysiological explanations. Plausible underlying mechanisms relating to cerebral hypoperfusion or occult cerebrovascular disease have been described and it seems likely that these may coexist and exert synergistic effects. Despite the prevalence of the two conditions, when cognitive impairment coexists with heart failure there is no specific guidance on treatment. Institution of evidence-based heart failure therapies that reduce mortality and hospitalisations seems intuitive and there is no signal that these interventions have an adverse effect on cognition. However, cognitive impairment will present a further barrier to the often complex medication self-management that is required in contemporary heart failure treatment

The ‘EDHF’ Antagonist 14, 15 Epoxyeicosa-5(Z)-Enoic Acid has Vasodilator Properties in Mesenteric Vessels

There is now overwhelming evidence for Epoxyeicosatrienoic acids (EETs) as endothelial derived hyperpolarising factor (EDHF). Most recently, a number of pharmacological tools have been developed for the study of EETs in relation to EDHF responses. EETs have been shown to cause relaxation by activating smooth muscle large conductance Ca2+ sensitive K+ (BKCa) (Archer et al, 2003). This dilatory response has been shown to be specifically inhibited by its analogue 14, 15-epoxyeicosa-5 (Z) enoic acid (14, 15 EEZE) in both human internal mammary artery and bovine coronary artery (Archer et al, 2003). Here we have investigated the antagonist effects of 14, 15 EEZE in murine arteries. Male Black 6 mice (12-18 weeks) were killed by lethal exposure to CO2. First order arteries were isolated and mounted in wire myographs immersed in physiological salt solution (PSS). Arteries were equilibrated (30 mins) and tensions normalised as described previously (Mulvany and Halpern, 1977). Arteries incubated for 30 minutes with or without 3µg/ml 14, 15 EEZE. A concentration response curve to 11, 12 EET was performed cumulatively on arteries pre-contracted with EC80 U46619. In some experiments, arteries were pre-contracted with EC80 U46619, and concentration response to 14, 15 EEZE performed cumulatively.Non peer reviewe

Smoothing dynamic positron emission tomography time courses using functional principal components

A functional smoothing approach to the analysis of PET time course data is presented. By borrowing information across space and accounting for this pooling through the use of a nonparametric covariate adjustment, it is possible to smooth the PET time course data thus reducing the noise. A new model for functional data analysis, the Multiplicative Nonparametric Random Effects Model, is introduced to more accurately account for the variation in the data. A locally adaptive bandwidth choice helps to determine the correct amount of smoothing at each time point. This preprocessing step to smooth the data then allows Subsequent analysis by methods Such as Spectral Analysis to be substantially improved in terms of their mean squared error

Reliability analysis of a structural ceramic combustion chamber

The Weibull modulus, fracture toughness and thermal properties of a silicon nitride material used to make a gas turbine combustor were experimentally measured. The location and nature of failure origins resulting from bend tests were determined with fractographic analysis. The measured Weibull parameters were used along with thermal and stress analysis to determine failure probabilities of the combustor with the CARES design code. The effect of data censoring, FEM mesh refinement, and fracture criterion were considered in the analysis

Radical Reconstruction of Complex Cranio-Orbito-Facial Abnormalities

Excellent cosmetic results can be obtained by early intervention in severe cranial-orbital-facial deformity. This intervention should take the form of a combined intracranial and extracranial approach. While the procedure is of great magnitude, the benefits to the patient and to the family seem worth the risk

The study of socioethical issues in systems biology

Systems biology is the rapidly growing and heavily funded successor science to genomics. Its mission is to integrate extensive bodies of molecular data into a detailed mathematical understanding of all life processes, with an ultimate view to their prediction and control. Despite its high profile and widespread practice, there has so far been almost no bioethical attention paid to systems biology and its potential social consequences. We outline some of systems biology's most important socioethical issues by contrasting the concept of systems as dynamic processes against the common static interpretation of genomes. New issues arise around systems biology's capacities for in silico testing, changing cultural understandings of life, synthetic biology, and commercialization. We advocate an interdisciplinary and interactive approach that integrates social and philosophical analysis and engages closely with the science. Overall, we argue that systems biology socioethics could stimulate new ways of thinking about socioethical studies of life sciences.ESRC; AHR

Language Ideologies in the Linguistic Landscape of One University in South Africa

This paper explores the language ideologies reflected on the linguistic landscape of one South African university. The main aim of this paper is to show how the language ideology of an institution or a community is reflected on its landscape (signs, billboards, notice boards, buildings). It also argues that there is a mismatch between the language policy put in place and the actual practice. The findings from this study are examined using studies on language ideologies and linguistic landscapes. The paper suggests that the linguistic landscape of an institution or a community should be an actual representation of its people’s language practices and should tie or match with the language policy put in place.
