A deep residual architecture for skin lesion segmentation

In this paper, we propose an automatic approach to skin lesion region segmentation based on a deep learning architecture with multi-scale residual connections. The architecture of the proposed model is based on UNet [22] with residual connections to maximise the learning capability and performance of the network. The information lost in the encoder stages due to the max-pooling layer at each level is preserved through the multi-scale residual connections. To corroborate the efficacy of the proposed model, extensive experiments are conducted on the ISIC 2017 challenge dataset without using any external dermatologic image set. An extensive comparative analysis is presented with contemporary methodologies to highlight the promising performance of the proposed methodology

An Analysis of Tax Incentives in the FDI Decision Process from Organisational Structural Perspectives: Evidence from UK Multinationals

This paper investigates the role of tax incentives in the FDI decision making process in a sample of UK multinational companies. The paper considers the relative importance of stages and determinants in the FDI decision making process. The determining factors in FDI decision process are examined from the organisational structure perspectives –FDI ownership form and market entry mode. The paper specifically identifies the role of tax in the strategic decisions of FDI organisational structure, as well as the stages of FDI decision making process. Relatively few prior empirical studies have examined the interface between tax strategy and corporate strategy in the context of FDI organisational structure and decision making process. This paper therefore attempts to examine the tax incentives for FDI decision process from the perspectives of the organisational structure

Processes Underlying MNE Subsidiary Absorptive Capacity: Evidence from Emerging Markets

We explore the determinants of absorptive capacity by examining how managers of MNE subsidiaries operating in emerging markets recognize, assimilate and apply external knowledge. From analysis of the subsidiaries of 12 MNEs with data from a total of 62 informants from China, India, Brazil and Kenya, six constructs emerged: prior knowledge significance, unlearning, explorative scanning, transformative learning, exploitative application and organization context. Through the iteration of data and theory, we develop a model, which presents a process framework that suggests the dynamic relationships among the emergent concepts underlying absorptive capacity. By identifying and explicating key actions and practices that have previously been largely treated as implicit in the absorptive capacity literature, the study enriches understanding of the micro-processes of absorptive capacity

Transport strategy in Scotland since devolution

This article critically reviews how the Scottish Executive's approach to transport has developed since devolution. Although there is much to commend, a number of concerns can be identified, including the possibility that a number of strategic infrastructure schemes appear to have been approved on political rather than on technical grounds. It is difficult to know whether the current set of transport infrastructure investment plans represents good value for public money

Do institutional arrangements make a difference to transport policy and implementation? Lessons for Britain

This paper describes local government decision-making in transport in three areas of the UK, London, West Yorkshire and Edinburgh, in which major changes in local government decision-making structures have taken place over the last decade, and between which arrangements are now very different. The research discusses whether institutional change has had a beneficial or adverse effect, and whether any of the current structures provides a more effective framework for policy development and implementation. The results show that although the sites share a broadly common set of objectives there are differences in devolved responsibilities and in the extent to which various policy options are within the control of the bodies charged with transport policy delivery. The existence of several tiers of government, coupled with the many interactions required between these public sector bodies and the predominantly private sector public transport operators appears to create extra transactional barriers and impedes the implementation of the most effective measures for cutting congestion. There is, however, a compelling argument for the presence of an overarching tier of government to organise travel over a spatial scale compatible with that of major commuter patterns. The extent to which such arrangements currently appear to work is a function of the range of powers and the funding levels afforded to the co-ordinating organisation

Interpreting physical performance in professional soccer match-play: Should we be more pragmatic in our approach?

Academic and practitioner interest in the physical performance of male professional soccer players in the competition setting determined via time-motion analyses has grown substantially over the last four decades leading to a substantial body of published research and aiding development of a more systematic evidence-based framework for physical conditioning. Findings have forcibly shaped contemporary opinions in the sport with researchers and practitioners frequently emphasising the important role that physical performance plays in match outcomes. Time-motion analyses have also influenced practice as player conditioning programmes can be tailored according to the different physical demands identified across individual playing positions. Yet despite a more systematic approach to physical conditioning, data indicate that even at the very highest standards of competition, the contemporary player is still susceptible to transient and end-game fatigue. Over the course of this article, the author suggests that a more pragmatic approach to interpreting the current body of time-motion analysis data and its application in the practical setting is nevertheless required. Examples of this are addressed using findings in the literature to examine: a) the association between competitive physical performance and ‘success’ in professional soccer, b) current approaches to interpreting differences in time-motion analysis data across playing positions and, c) whether data can realistically be used to demonstrate the occurrence of fatigue in match-play. Gaps in the current literature and directions for future research are also identified
