Coastal tidal effects on thermal plumes are investigated, exploiting remote sensing of two major coastal industrial installations. The installations use sea water as a coolant, which is then released back into coastal environments at a higher-than-ambient temperature, allowing the plume to be delineated from the ambient waters. Satellite-based thermal sensors observing the Earth at spatial resolutions of 90 and 100 m are used. It is possible to identify coastal features and thermal spatial distributions. This paper presents coastal tidal effects on detected plumes for two case studies: an intertidal embayment and open water exposure, both on the coast of the UK. We correlated the behaviours of thermal plumes using remotely sensed high resolution thermal imagery with tidal phases derived from tide gauges. The results show very distinct behaviours for the flood and ebb tides. The detected surface plume location was dependent on flow switching direction for the different types of tide. The detected surface area was dependent on the strength of the currents, with the largest area observed during the strongest currents. Understanding the dispersion of the plume is essential to influence understanding of any potential ecological impacts.

Over Time

Salt marshes are important coastal environments and provide multiple benefits to society. They are considered to be declining in extent globally, including on the UK east coast. The dynamics and characteristics of interior parts of salt marsh systems are spatially variable and can fundamentally affect biotic distributions and the way in which the landscape delivers ecosystem services. It is therefore important to understand, and be able to predict, how these landscape configurations may evolve over time and where the greatest dynamism will occur. This study estimates morphodynamic changes in salt marsh areas for a regional domain over a multi-decadal timescale. We demonstrate at a landscape scale that relationships exist between the topology and morphology of a salt marsh and changes in its condition over time. We present an inherently scalable satellite-derived measure of change in marsh platform integrity that allows the monitoring of changes in marsh condition. We then demonstrate that easily derived geospatial and morphometric parameters can be used to determine the probability of marsh degradation. We draw comparisons with previous work conducted on the east coast of the USA, finding differences in marsh responses according to their position within the wider coastal system between the two regions, but relatively consistent in relation to the within-marsh situation. We describe the sub-pixel-scale marsh morphometry using a morphological segmentation algorithm applied to 25 cm-resolution maps of vegetated marsh surface. We also find strong relationships between morphometric indices and change in marsh platform integrity which allow for the inference of past dynamism but also suggest that current morphology may be predictive of future change. We thus provide insight into the factors governing marsh degradation that will assist the anticipation of adverse changes to the attributes and functions of these critical coastal environments and inform ongoing ecogeomorphic modelling developments.

This paper shows simulations of high waves over different bathymetries to collect statistical information, particularly kurtosis and crest exceedance, that quantifies the occurrence of exceptionally extreme waves. This knowledge is especially pertinent for the design and operation of marine structures, safe ship trafficking, and mooring strategies for ships near the coast. Taking advantage of the flexibility to perform numerical simulations with HAWASSI software, with the aim of investigating the physical and statistical properties for these cases, this paper investigates the change in wave statistics related to changes in depth, breaking and differences between long- and short-crested waves. Three different types of bathymetry are considered: run-up to the coast with slope 1/20, waves over a shoal, and deep open-water waves. Simulations show good agreement in the examined cases compared with the available experimental data and simulations. Then predictive simulations for cases with a higher significant wave height illustrate the changes that may occur during storm events.

The primary concern of this paper is to investigatethe extent to which three variables (i.e. personality traits, demographic variables, and job satisfaction) are interrelated with each other and what effect they have on each other in relation to the UK retail sector. The four different types of retail stores i.e. Tesco, Primark, Ikea and WH Smith were selected for survey purpose to minimise the class biasness.Total 300 close-ended questionnaires were distributed and 220 responses were obtained.The findings reveal that ‘Neuroticism’ is negatively associated with job satisfaction as well as with ‘Extraversion’. However, it is positively correlated with other three personality groups including ‘Agreeableness’, ‘Conscientious’, and ‘Openness’. On the other hand, ‘Openness to experience’ has a negative relationship with ‘Agreeableness’.It is also found from the ranking analysis that employees with ‘Agreeableness’ and ‘Conscientiousness’ personalities are more successful in their career and consequently they are more satisfied with their jobs.

Learning Issues

In the current landscape of higher education in the UK, international students play a key role. It is an environment in which they not only cross borders physically but also transition through various identities as they develop their professional and linguistic confidence and skills to fully access and contribute to their programme of study and beyond. The aim of this paper is to outline the results of an empirical investigation into Chinese students’ perceptions of their study experiences in the context of student mobility and English-medium instruction in higher education. It reports on a study of two groups of Chinese students – one group studying in an English-speaking environment, the other in their home country where instruction is delivered through the medium of English. Semi-structured focus group interviews were conducted at each site which focused on the transition of “crossing borders” for educational purposes. The data was analysed using thematic analysis (Clarke & Braun, 2016). The main finding was that both groups experienced remarkably similar learning issues, despite being located in very different learning environments and crossing different types of borders.

Spring Sowing

The effect of sea floods on grassland is described and recommendations are made for the restoration of inundated grassland. Turf may be heavily damaged after +or- 4 weeks inundation with water containing more than 20 g. NaCl per 1. At lower salt concentrations Poa sp. and Trifolium repens are still badly damaged but other species, notably Lolium perenne, Agrostis stolonifera and Alopecurus sp., are capable of immediate regrowth after drainage. If grassland remains submerged during spring, rising temperatures promote active growth of the grasses followed by rapid decay caused by lack of oxygen. L. perenne is especially sensitive to submergence in warm weather. The dominant weed communities which appear on land on which the turf has been destroyed by sea-water are described. Reseeding is recommended as the quickest method of restoring badly damaged turf. The flooded land should first be thoroughly drained and then repeatedly harrowed to produce a shallow seed-bed on which herbage mixtures can be sown without the application of gypsum. Given average weather conditions, normal permanent grassland mixtures can be sown at salt concentrations, measured in spring, of up to 8-10 g. NaCl per 1. of moisture in the 5-20 cm. soil layer. At a salt concentration of about 10 g. per 1. measured in spring, L. perenne tends to dominate over other species while Poa sp. and T. repens suffer during the summer. At a salt concentration of 10-15 g. per 1. in spring, Poa sp. and T. repens should be omitted from seed mixtures, instead mixtures consisting of different types of L. perenne, Festuca pratensis and Phleum pratense should be sown. When the salt concentration of the soil moisture is higher that 15 g. per 1. in spring, sowing should be delayed and the weeds checked by mowing or grazing. Temporary rises of the salt concentration in dry symmers to 25 g. per 1. are tolerated by L. perenne, F. pratensis and Ph. pratense; similar rises up to 15-18 g. per 1. are tolerated by Poa sp. and T. repens.-W.J.B.

AbstractPsychosocial Interventions (PSIs) and PSI supervision underpin the delivery of early interventions for people experiencing psychosis. Early Intervention (EI) teams are relatively new in the NHS and there is currently a lack of empirical research into PSI supervision in this area. This study aimed to elicit staff views of PSI supervision and to identify any unmet supervision needs within a newly developed EI team in the UK. Semi-structured interviews were conducted with 16 multidisciplinary team members. Descriptive statistics and a thematic analysis were used to analyse the responses. The different types of supervision available to team members, gaps in the provision of PSI supervision and aspects that supervisees found helpful and unhelpful about PSI supervision are discussed as are ideas for improving the provision of PSI supervision in EI teams. The limitations of the study and ideas for further research are also outlined.

Stresses that the criminal economy is much more cash‐intensive than the legitimate economy, and explains why. Indicates the scope of the problem for crime control: that carrying illegal proceeds as cash across national border remains an important method of money laundering. Outlines the provisions of the Proceeds of Crime Act 2002 concerning powers to allow searches for cash, and the standard of proof required. Discusses the different types of evidence allowed: avoidance of the usual banking channels, previous convictions and acquittals, lack of business records, lack of an audit trail, credibility, presence of items indicating crime, criminal associates, lying and inconsistent statements, contamination of the cash by drugs, suspicious denomination of banknotes, attempts at concealment, travel destinations and arrangements, financial background, failure to cooperate, and confidential informants. Goes on to cash seizures under terrorist legislation, possible challenges to seizures as contrary to the European Convention on Human Rights, the choice between civil and criminal forfeiture, and how the investigation proceeds.

Funding of higher education institutions is a major growing expense for the Oman government (13–14% of the total spending in 2016) and is at par with that of other governments (e.g., 11% in the UK and 15.5% in the US). However, there has been little investigation into the funding of quality higher education in Oman. The present research project aims to explore the sources of funding at Oman universities after it opened the private education sector in 1996. The research methodology includes conducting interviews with leaders in higher education to explore different types of funding (e.g., gifts, tuition fees, government support). This will enhance our understanding, as well as that of decision-makers, regarding universities' funding sources and of the higher education landscape.
