From Insularity to Islandness: The use of place branding to achieve sustainable island tourism

This paper aims to outline the role that place branding plays in shaping a new framework for sustainable island tourism. Islandness, as a contemporary context, underlines that islands share a set of unique features and they need to be studied on their own terms; they combine elements of urban and rural regions at the same time. Place branding is evolving as a crucial element for differentiated marketing that conditionally can also form an alternative tool to achieve sustainability for island regions. Therefore, policy makers need to examine tourism policies for island regions through the lenses of Nissology. It is commonly accepted that globalisation has intensified the competition between countries, cities and regions to attract investment, high quality human capital, various potential audiences and visitors. Several factors play a significant role in shaping the context in which places develop nowadays: climate change, new technologies, tourism pressures are just a few to highlight from the public discussion and academic debates. A growing number of researchers argue that place branding could be the strategic planning procedure needed, able to achieve multifaceted sustainability of an island destination. One very important issue raised often by both academics and practitioners is the role of stakeholders and local governance in such strategic processes like sustainable tourism development of a destination. The literature review, in this paper, explores why islandness and place branding have become significant for islands’ sustainable tourism development. Therefore, building on existing cross-discipline theoretical foundations, the present paper aims to (a) highlight the link between islandness and contemporary place branding, (b) emphasise the need to establish the term ‘island branding’, and (c) suggest a potential framework deriving from this linkage as a proper solution for contributing to the next era of sustainable tourism development for island regions

COMET: Communication-optimised multi-threaded error-detection technique

© 2016 ACM. Relentless technology scaling has made transistors more vulnerable to soft, or transient, errors. To keep systems robust against these, current error detection techniques use different types of redundancy at the hardware or the software level. A consequence of these additional protection mechanisms is that these systems tend to become slower. In particular, software error-detection techniques degrade performance considerably, limiting their uptake. This paper focuses on software redundant multi-threading error detection, a compiler-based technique that makes use of redundant cores within a multi-core system to perform error checking. Implementations of this scheme feature two threads that execute almost the same code: the main thread runs the original code and the checker thread executes code to verify the correctness of the original. The main thread communicates the values that require checking to the checker thread to use in its comparisons. We identify a major performance bottleneck in existing schemes: poorly performing inter-core communication and the generated code associated with it. Our study shows this is a major performance impediment within existing techniques since the two threads require extremely fine-grained communication, on the order of every few instructions. We alleviate this bottleneck with a series of code generation optimisations at the compiler level. We propose COMET (Communication-Optimised Multi-threaded Error-detection Technique), which improves performance across the NAS parallel benchmarks by 31.4% (on average) compared to the state-of-the-art, without affecting fault-coverage

Life-Cycle Cost Model and Design Optimization of Base-Isolated Building Structures

Design of economic structures adequately resistant to withstand during their service life, without catastrophic failures, all possible loading conditions and to absorb the induced seismic energy in a controlled fashion, has been the subject of intensive research so far. Modern buildings usually contain extremely sensitive and costly equipment that are vital in business, commerce, education and/or health care. The building contents frequently are more valuable than the buildings them-selves. Furthermore, hospitals, communication and emergency centres, police and fire stations must be operational when needed most: immediately after an earthquake. Conventional con-struction can cause very high floor accelerations in stiff buildings and large interstorey drifts in flexible structures. These two factors cause difficulties in insuring the safety of both building and its contents. For this reason base-isolated structures are considered as an efficient alternative design practice to the conventional fixed-base one. In this study a systematic assessment of op-timized fixed and base-isolated reinforced concrete buildings is presented in terms of their initial and total cost taking into account the life-cycle cost of the structures

Relevance of pharmacogenomics for developing countries in Europe : implementation in the Maltese population

Pharmacogenomics is a promising new discipline that can realize personalized treatment for patients suffering from many common diseases, particularly those with multiple treatment modalities. Recent advances in the deciphering of the human genome sequence and high throughput genotyping technology have led to the reduction of the overall genotyping costs and enabled the inclusion of genotype-related dosing recommendations into drug package inserts, hence allowing the integration of pharmacogenomics into clinical practice. Although, pharmacogenomics gradually assumes an integral part in mainstream medical practice in developed countries, many countries, particularly from the developing world, still do not have access either to the knowledge or the resources to individualize drug treatment. The PharmacoGenetics for Every Nation Initiative (PGENI) aims to fill in this gap, by making pharmacogenomics globally applicable, not only by defining population-specific pharmacogenomic marker frequency profiles and formulating country-specific recommendations for drug efficacy and safety but also by increasing general public and healthcare professionals’ awareness over pharmacogenomics and genomic medicine. This article highlights the PGENI activities in Europe and its implementation in the Maltese population, in an effort to make pharmacogenomics readily applicable in European healthcare systems.peer-reviewe

Lynx: Using OS and hardware support for fast fine-grained inter-core communication

Designing high-performance software queues for fast intercore communication is challenging, but critical for maximising software parallelism. State-of-the-art single-producer / single-consumer queues for streaming applications contain multiple sections, requiring the producer and consumer to operate independently on different sections from each other. While these queues perform well for coarse-grained data transfers, they perform poorly in the fine-grained case. This paper proposes Lynx, a novel SP/SC queue, specifically tuned for fine-grained communication. Lynx is built from the ground up, reducing the generated code on the critical-path to just two operations per enqueue and dequeue. To achieve this it relies on existing commodity processor hardware and operating system exception handling support to deal with infrequent queue maintenance operations. Lynx outperforms the state-of-the art by up to 1.57× in total 64-bit throughput reaching a peak throughput of 15.7GB/s on a common desktop system. Real applications using Lynx get a performance improvement of up to 1.4×.This work was supported by the Engineering and Physical Sciences Research Council (EPSRC), through grant reference EP/K026399/1.This is the author accepted manuscript.
