This chapter provided systematic and comprehensive analysis on trawl fisheries management and conservation measures in the Straits of Malacca. Detailed analysis is conducted on Malaysian fishery management framework particularly domestic country's trawl fishery status, legal structure, input-control strategies, ecosystem protection plan, pollution, law enforcement, and complementary measures that designed to reduce and prevent overfishing in the exclusive economic zone (EEZ) of Malacca Straits. Gaps and challenges found in existing trawl fisheries literature are presented followed by recommendations for improvement in the management and conservation of trawl fisheries.

Aquaculture has become the world’s fastest growing food-production technology. This chapter outlines the main factors for this growth and shows how farmed seafood can contribute directly and indirectly to food security. We used the databases of the FAO on food production and trade to analyze the development of production in the main categories of animal protein. The trends were interpreted in a productivity growth and trade context. We found that modern aquaculture is enabled by transferring knowledge from terrestrial animal production and from developing new technologies to create substantial productivity growth and production cost reductions. The current growth rate of aquaculture production exceeds all other types of meat production and is expected to continue to increase as the agro-science industry expands (seafood made up 34.5% of the world’s animal production in 2013). More than 90% of the world’s aquaculture production takes place in developing countries, where it contributes to food security directly through consumption or indirectly as a source of income. Seafood is a main source of animal protein in many parts of the world, particularly in developing countries. Depending on species and country, farmed seafood contributes to food security directly through domestic consumption, or indirectly through economic growth from exports.

The purpose of this study was to identify the transformation disclosures in the publicly available annual reports of South African public universities and to establish the extent to which universities account to their stakeholders about how they have discharged their transformation obligations.

This exploratory qualitative study involves a thematic content analysis of publicly available annual reports using ATLAS.ti software to identify and categorise transformation interventions disclosed by South African public universities.

This empirical study identifies several interventions that universities have introduced to facilitate access to and successful completion of tertiary studies by students. Some of the disclosed mechanisms include the provision of financial aid, student support and counselling, tutoring and mentoring and ICT enhancements and the introduction of language policies. The results also highlighted several challenges to sustainable transformation including funding, social and academic barriers and infrastructural challenges experienced by universities.

According to the authors’ knowledge, this study represents one of the first studies to use the public disclosures in the annual reports of public universities to identify interventions introduced to facilitate transformation of the student body. Despite its South African orientation, the observations have implications for universities worldwide experiencing similar challenges, especially in developing countries.

We introduce a second‐order accurate time‐marching pressure‐correction algorithm to accommodate weakly‐compressible highly‐viscous liquid flows at low Mach number. As the incompressible limit is approached (Ma ≈ 0), the consistency of the compressible scheme is highlighted in recovering equivalent incompressible solutions. In the viscous‐dominated regime of low Reynolds number (zone of interest), the algorithm treats the viscous part of the equations in a semi‐implicit form. Two discrete representations are proposed to interpolate density: a piecewise‐constant form with gradient recovery and a linear interpolation form, akin to that on pressure. Numerical performance is considered on a number of classical benchmark problems for highly viscous liquid flows to highlight consistency, accuracy and stability properties. Validation bears out the high quality of performance of both compressible flow implementations, at low to vanishing Mach number. Neither linear nor constant density interpolations schemes degrade the second‐order accuracy of the original incompressible fractional‐staged pressure‐correction scheme. The piecewise‐constant interpolation scheme is advocated as a viable method of choice, with its advantages of order retention, yet efficiency in implementation.

The present work involves analytical and experimental investigation of sloshing in a two-dimensional rectangular tank including the effect of porous baffles to control and/or reduce the wave motion in the sloshing tank. The purpose of this study is to assess the analytical solutions of the drag coefficient effect on porous baffles performance to track free surface motion variation in the sloshing tank by comparison with experimental shake table tests under a range of sway excitation.

The linear second-order ordinary differential equations for liquid sloshing in the rectangular tank were solved using Newmark’s beta method and obtained the analytical solutions for liquid sloshing with dual vertical porous baffles of full submergence depths in a sway-oscillated rectangular tank following the methodology similar to Warnitchai and Pinkaew (1998) and Tait (2008).

The porous baffles significantly reduce wave elevation in the varying filled levels of the tank compared to the baffle-free tank under the range of excitation frequencies. It is observed that the Reynolds number-dependent drag coefficient for porous baffles in the tank can significantly reduce the sloshing elevations and is found to be effective to achieve higher damping compared to the porosity-dependent drag coefficient for porous baffles in the sloshing tank. The analytical model’s response to free surface elevation variations in the sloshing tank was compared with the experiment’s test results. The analytical results matched with shake table test results with a quantitative difference near the first resonant frequency.

The scope of the study is limited to porous baffles performance under range sway motion and three different filling levels in the tank. The porous baffle performance includes Reynolds number dependent drag coefficient to explore the damping effect in the sloshing tank.

The porous baffles with low-level porosities in the sloshing tank have many engineering applications where the first resonant mode of sloshing in the tank is more important. The porous baffle drag coefficient is an important parameter to study the baffle’s damping effect in sloshing tanks. Hence, obtained analytical solution for liquid sloshing in the rectangular tank with Reynolds number as well as porosity-dependent drag coefficient (model 1) and porosity-dependent drag coefficient porous baffles (model 2) performance is discussed. The model’s test results were validated using a series of shake table sloshing experiments for three fill levels in the tank with sway motion at various excitation frequencies covering the first four sloshing resonant modes.

The protracted and multidisciplinary nature of paediatric cochlear implantation presents particular challenges in addressing issues of clinical governance. The implantation process is one that involves many disciplines in acute and community settings over several years. Reviews the difficulties presented by a protracted, multidisciplinary intervention for addressing issues of clinical governance within the context of paediatric cochlear implantation. Discusses the activities of the Nottingham Paediatric Cochlear Implant Programme in tackling these problems and gives some details of its progress and success in these areas.

The South African medical fraternity is existing within an increasingly turbulent environment, characterised by government interference, budget cuts, restrictive legislation, as well as diseases which threaten the very basis on which this fraternity exits. The medical profession exists within the ambit of services marketing. Attempts to improve the service delivery should be studied within this framework. Medical doctors are in short supply and complaints regarding the services provided are increasing. The focus of the article is on current and potential patients of general medical practitioners in Port Elizabeth, South Africa. The sample size was 500, which yielded 156 useable questionnaires. The response rate of 31.2 per cent was regarded as acceptable. The location of the practice of the medical practitioner and personal loyalty of the patient towards the medical practitioner, are of vital importance in determining whether the patient will return or not, and whether a positive perception will be developed.

An inter‐disciplinary approach is adopted to provide a deeper understanding of the human resource‐service quality relationship. The paper tests the relationships organisational commitment and job satisfaction have with service quality of customer‐contact employees. Hypotheses are constructed by reviewing literature in the areas of human resource management and services marketing. A study comprising 342 employees was conducted in four telephone call centres of a major UK retail bank. Investigates how different forms of organisational commitment and job satisfaction influence the service quality delivered by contact employees. Findings indicate that job satisfaction and organisational commitment of employees have a significant impact on service quality delivered. The affective component of commitment was found to be more important than job satisfaction in determining service quality of customer‐contact employees.

This paper traces the innovative development of the Nottingham Cochlear Implant Programmes. The paediatric programme was the first to be established in the UK in 1989 and remains the largest programme in the UK today, whilst the adult programme developed later, in 1994. The first section of the paper describes trends in service development whilst the second section makes detailed reference to the history of funding arrangements which enabled the programme to become established. The third part of the paper examines the (de)merits of locality purchasing versus centralised purchasing for specialist services, using cochlear implantation as way of illustration. The paper aims to provide an informative history of the development of the service in Nottingham and from this background create debate as to the most appropriate future funding mechanism for cochlear implantation in particular and specialist services in general.

The benefits and problems associated with firm-generated content (FGC) as a key driver of sponsorship effectiveness demand more research attention. Accordingly, the purpose of this paper is to consider the effect of content marketing on sponsorship-response favorability in the South African energy drink market.

It is theorized that in an FGC environment, sponsor factors, sponsorship factors and event factors drive sponsorship favorability. This notion is tested using a structural equations model among 18- to 35-year-olds.

The results show acceptable model fit and confirm the usefulness of understanding the effects of content marketing on sponsorship favorability. The authors also offer directions for future research.

The results suggest that FGC which is well-designed, packaged and presented can enhance the views of individuals regarding a sponsor – even if the brand operates in a background position as opposed to the conventional foreground position common in promotional material.

The current study considers content marketing in contexts that have largely been avoided so far, or have only featured on a very limited scale in the literature. This study was conducted in an emerging market, business-to-consumer and sponsorship context for the application of a content marketing strategy.
