Ecosystem modelling of tropical wetlands

4.1 Background Modelling is essential for enhancing our understanding of the functioning of tropical wetland ecosystems, and for simulating future trajectories and testing for system thresholds. Anthropogenic activities such as drainage and land-use change can be integrated in models and their impacts on fluxes of greenhouse gas concentrations simulated. Models can also be used to test the response of peatlands and mangroves to climate extremes, variability and change, and to estimate reference levels and greenhouse gas emissions scenarios in the framework of climate change mitigation projects such as REDD+. In coastal settings, models are used to explore wetland resilience to sea-level rise. Finally, models can also be developed to support the decision making process by providing policyrelevant information on the consequences and trade-offs of adopting different management and climate scenarios

The Intramolecular Loss of Fluorescence by Lysine Derivatized with Naphthalenedialdehyde

This is the publisher's version, also available electronically from http://www.opticsinfobase.org/as/abstract.cfm?URI=as-44-5-858.Derivatization of primary amines such as amino acids and peptides with naphthalenedialdehyde (NDA) in the presence of cyanide ion yields cyanobenzo[f]-isoindole (CBI) adducts that are highly fluorescent. However, the fluorescence is seriously quenched with amines that possess more than one primary amine site, as is the case with lysine. Although it was found that the adsorption of CBI2-lysine on a solid substrate restored the fluorescence, the reason for the solution quenching, with respect to results for mono-derivatized amines, was investigated. The experiments to probe the quenching were based on the assumption that the mechanism responsible for quenching involved a charge-transfer (CT) excited state. Thus, it was found that the solvent properties of viscosity and polarity affected the lifetime and quantum yield of fluorescence in a manner consistent with the proposed mechanism

New approaches to mapping and managing palaeochannel resources in the light of future environmental change : a case study from the Trent Valley, UK

Abandoned river channels may provide rich primary sources of palaeoenvironmental and cultural information elucidating landscape evolution, climate change, vegetation history and human impact, especially since the beginning of the Holocene epoch. However, although potentially an important resource, palaeochannels are not often recorded systematically and only rarely enjoy robust statutory protection (in the UK as Sites of Special Scientific Interest). In consequence, it is challenging to mitigate and manage this important geoarchaeological resource effectively within the UK planning framework. Whilst palaeochannels have long been recognised on aerial photographs and historic maps, the advent of airborne laser scanning (Lidar) and other remote-sensing technologies has provided a hitherto unforeseen opportunity to record such landforms and related features at a catchment scale. This paper provides a case study from the Nottinghamshire reach of the Trent Valley, where a desk-based methodology that is now being extended across the entire catchment has been developed for recording, geospatially locating and defining the attributes of observed palaeochannels. After outlining the methodology, we consider how this approach to resource management can aid archaeological research and future heritage management, especially in the light of predicted climate and environmental change

On the public discourse of religion : an analysis of Christianity in the United Kingdom

Debates over the involvement of religion in the public sphere look set to be one of the defining themes of the 21st century. But while religious issues have attracted a large degree of scholarly attention, the public discourse of religion itself, in terms of the effort to assert and legitimize a role for faith in the public realm, has remained notably under-researched. This article marks an initial step to address this deficiency by deconstructing the public discourse of Christianity in the United Kingdom. It argues that, while appealing for representation on the grounds of liberal equality, the overall goal of this discourse is to establish a role for itself as a principal source of moral authority, and to exempt itself from the evidentially-based standards and criteria that govern public life

Implications of the problem orientated medical record (POMR) for research using electronic GP databases: a comparison of the Doctors Independent Network Database (DIN) and the General Practice Research Database (GPRD).

Background The General Practice Research Database (GPRD) and Doctor's Independent Network Database (DIN), are large electronic primary care databases compiled in the UK during the 1990s. They provide a valuable resource for epidemiological and health services research. GPRD (based on VAMP) presents notes as a series of discrete episodes, whereas DIN is based on a system (MEDITEL) that used a Problem Orientated Medical Record (POMR) which links prescriptions to diagnostic problems. We have examined the implications for research of these different underlying philosophies. Methods Records of 40,183 children from 141 practices in DIN and 76,310 from 464 practices in GRPD who were followed to age 5 were used to compare the volume of recording of prescribing and diagnostic codes in the two databases. To assess the importance and additional value of the POMR within DIN, the appropriateness of diagnostic linking to skin emollient prescriptions was investigated. Results Variation between practices for both the number of days on which prescriptions were issued and diagnoses were recorded was marked in both databases. Mean number of "prescription days" during the first 5 years of life was similar in DIN (19.5) and in GPRD (19.8), but the average number of "diagnostic days" was lower in DIN (15.8) than in GPRD (22.9). Adjustment for linkage increased the average "diagnostic days" to 23.1 in DIN. 32.7% of emollient prescriptions in GPRD appeared with an eczema diagnosis on the same day compared to only 19.4% in DIN; however, 86.4% of prescriptions in DIN were linked to an earlier eczema diagnosis. More specifically 83% of emollient prescriptions appeared under a problem heading of eczema in the 121 practices that were using problem headings satisfactorily. Conclusion Prescribing records in DIN and GPRD are very similar, but the usage of diagnostic codes is more parsimonious in DIN because of its POMR structure. Period prevalence rates will be underestimated in DIN unless this structure is taken into account. The advantage of the POMR is that in 121 of 141 practices using problem headings as intended, most prescriptions can be linked to a problem heading providing a specific reason for their issue
