Abstract

Reports a laboratory comparison of the effectiveness and efficiency of five index languages in the subject area of library and information science; three post‐co‐ordinate languages, Compressed Term, Uncontrolled, and Hierarchically Structured, and two pre‐co‐ordinate ones, Hierarchically Structured and Relational Indexing. Eight test comparisons were made, and factors studied were index language specificity and linkage, indexing specificity and exhaustivity, method of co‐ordination, the precision devices of partitioning and relational operators, and the provision of context in the search file. Full details of the test and retrieval results are presented.

– The purpose of this paper is to summarise and analyse the new compensation provisions brought in by the government for Phase 1 of the HS2 high-speed train line.

Abstract

Purpose

The purpose of this paper is to summarise and analyse the new compensation provisions brought in by the government for Phase 1 of the HS2 high-speed train line.

Design/methodology/approach

To summarise each of the proposals and provide a critical assessment of each of them.

Findings

For the most part, and the Homeowner Payment Scheme (HPS) is a marked exception, the new HS2 compensation provisions set out a logical approach to reducing the impact of the scheme on the people most directly affected by its blighting affect. There are, however, a number of concerns as to whether there are more urgent reforms that have not been considered.

Research limitations/implications

The proposals were announced in April and in respect of some of them, particularly the HPS, very little information is available as yet.

Practical implications

The paper should provide factual information on a very new set of compensation provisions and a critical appraisal of their value.

Originality/value

As the compensation provisions have been published only recently there will be few other similar commentaries available.

The purpose of this paper is to provide an annual update on case law relating to compulsory purchase and compensation.

Abstract

Purpose

The purpose of this paper is to provide an annual update on case law relating to compulsory purchase and compensation.

Design/methodology/approach

Researching decisions made by the Court of Appeal and Upper Tribunal (Lands Chamber) in the field of compensation. Commentary on the legal and valuation implications of a selection of those cases is provided.

Findings

In the last year, there have been a number of interesting cases concerning residual valuations, blight caused by HS2, and Tree Preservation Orders.

Research limitations/implications

The research is limited by the case law available in the last 12 months and this has been a relatively quiet year.

Practical implications

The commentary should assist practitioners to formulate claims for compensation having regard to recent developments in case law.

Originality/value

Its originality and value lies in the fact that it is based on recent legal decisions which have not yet been widely reported.

Abstract

Purpose

The purpose of this paper is to investigate the fatigue performance of a welded detail from a composite steel-concrete railway twin girder bridge caused by a passenger train circulating at varying speeds, by identifying the dynamic amplification scenarios induced by resonance. For this purpose, the hotspot stress method is used, instead of the traditional nominal stress methods.

Design/methodology/approach

This paper assesses the fatigue behavior of a welded connection considering critical stress concentration locations (hotspot). Finite element analysis (FEA) is applied, utilizing both a global and a local submodel, made compatible by displacements field interpolation. The dynamic response is obtained through the modal superposition method. Stress cycles are extracted with the rainflow counting method and the fatigue damage is calculated with Palmgren-Miner’s rule. The feasibility of five submodels with different mesh densities, i.e. 1, 2, 4, 8 and 20 mm is verified.

Findings

An increase in the fatigue damage due to the resonance effect was found for the train traveling at a speed of 225 km/h. A good agreement between the computed fatigue damage for the submodels is achieved. However, a non-monotonic hotspot stress/fatigue damage vs mesh density convergence was observed with a peak observed for the 4 mm model, which endorses the mesh sensitivity that could occur when using the surface stress extrapolation detailed rules specified in the standards for the hotspot stress method.

Originality/value

Advanced dynamic analyses are proposed to obtain local stresses in order to apply a local method for the fatigue assessment of a bridge’s structure subjected to high-speed railway traffic on the basis of the mode superposition technique resulting in much less computing times.

To examine the general political structure and background to decision making in aviation policy.

Abstract

Purpose

To examine the general political structure and background to decision making in aviation policy.

Design/methodology/approach

Largely conceptual and theoretical, applied to political and historical examples.

Findings

That ‘politics as usual’ signifies a structure characterised by adherence to underlying presuppositions which guide political and economic action and that moves towards different ways of thinking and acting and that environmental policy faces an uphill battle in the light of these often unacknowledged and typically unquestioned presuppositions.

Practical implications

Political action requires an accurate understanding of the circumstances in which it is to be undertaken. This chapter provides a clue to that proper understanding and hence is valuable for the appropriate orientation of political action.

Originality/value

The chapter employs an everyday term, ‘politics as usual’, and analyses its structure, claiming that it identifies a real underlying set of default positions in politics.

Abstract

Purpose

This research bridges disparate research on servitization, namely product–service systems (PSS) and integrated solutions (IS), to provide valuable insights for the progression of the field. It acts as a reconciliation of these research streams and offers a reconceptualised agenda incorporating recent research on platforms, ecosystems, modularity, risk and governance as key conceptual themes to synthesise and build theory.

Design/methodology/approach

This is a conceptual, theory development article focused on advancing thinking on servitization by identifying systematic and theoretically informed research themes. It also proposes future research opportunities to advance theoretical contributions and practical implications for servitization research.

Findings

By reviewing and synthesising extant PSS and IS research, this article identified five core themes – namely modularity, platforms, ecosystems, risks and governance. The importance of these five themes and their linkages to PSS and IS are examined and a theoretical framework with a future research agenda to advance servitization is proposed.

Originality/value

This paper considers the similarities and differences between PSS and IS in order to develop a theory and to reconcile formerly disparate research efforts by establishing linkages between core themes and identifying valuable synergies for scholars. The importance of the core themes and current gaps within and across these themes are shown, and a mid-range theory for servitization is positioned to bridge the servitization-related PSS and IS communities.
