Abstract
Purpose – Urban and suburban arterials carry a large share of urban traffic and contend with a relatively large proportion of transport network crashes. Road crashes and their consequent societal costs diminish the sustainability of transportation systems, highlighting the need to identify road safety problems and their corresponding solutions. This chapter briefly outlines problems and solutions associated with crash risk on urban and suburban arterials. In addition, this chapter studies and discusses several safety countermeasures – ranging from local treatments to integral frameworks – and their effectiveness on improving traffic safety of urban and suburban arterials.
Approach – Crash occurrence on urban and suburban arterials is affected by numerous contributing factors. This chapter pays attention primarily to the effects of traffic characteristics and road design features. In this regard, several pertinent variables which have been extensively examined in the literature are reviewed and their contributions to the safety of urban and suburban arterials are discussed.
Findings – A review of the literature identifies a number of variables as influential factors of crashes on urban and suburban arterials. Although the associations of some variables (e.g., traffic volume) are consistent with expectations, others (e.g., lane width and speed) show mixed and sometimes counterintuitive results. These findings signify that additional research is needed to reveal the correct functional form and magnitude of these relationships.
Practical implications – The results show that while the general direction and magnitude of effects of some engineering and management-related treatments are known, additional research is needed to consolidate the impact and effectiveness of integrated approaches.

Abstract
Small and medium‐sized enterprises (SMEs) are increasingly making use of e‐commerce. This study seeks to identify the reasons that are causing such businesses to adopt e‐commerce (adoption intentions); the benefits they are realising from their e‐commerce developments; and, importantly, to determine if the areas identified as important are indeed those where benefits are being realised. It was found that responding to competitive pressure was the main reason leading companies to adopt e‐commerce. Information sharing and communication between employees within the firm were found to be the e‐commerce activities where firms are realising the greatest benefit. Areas where e‐commerce could be considered as “under‐performing” were found to be online recruitment and procurement. Areas that could be considered to be “over‐performing”, and hence may indicate an appropriate starting point for those firms yet to adopt e‐commerce, are in internal knowledge sharing and communication.

Abstract
This paper investigates the multi‐phase behaviour of droplets injected into a nozzle at two separate wall locations. The physical features of the droplets (rate of mass, density and radius) at each injector location are identical. This system can be described by a two‐phase Eulerian—Eulerian approach that yields classical systems of equations: three for the gaseous phase and three for the dispersed droplet phase. An underlying assumption in the two phase model is that no interaction occurs between droplets. The numerical solution of the model (using the MacCormack scheme) indicates however that the opposite jets do interact to form one jet. This inconsistency is overcome in the current paper by associating the droplets from a given injection location with a separate phase and subsequently solving equations describing a multiphase system (here, three‐phase system). Comparison of numerical predications between the two‐phase and the multiphase model shows significantly different results. In particular the multiphase model shows no jet interaction.

Abstract
Purpose
The aim of this study is to identify the travel constraints of people with special needs (PwSN) and the strategies used to overcome them. The article also intends to analyze the differences in travel constraints and negotiation strategies according to the type of disability and/or special need.
Design/methodology/approach
A qualitative study was conducted in which a sample of PwSN (people with disabilities – mobility, sensory and cognitive – seniors and people with food allergies) were interviewed in depth.
Findings
PwSN face a wide range of constraints when engaging in tourism activities. These constraints are very diverse and influence people with different intensity and have to be overcome using different negotiation strategies. However, differences in the constraints were observed according to the type of special needs.
Practical implications
One of the most significant practical implications of this research is the need for raising awareness regarding human diversity among tourism stakeholders. It is critical to link sectoral policies that are reflected in the social and business reality, creating public–private partnerships to raise the sharing of knowledge, equipment and services. By addressing the constraints that prevent PwSN from traveling, the tourism sector can create more opportunities for them to participate in social activities, improving their quality of life and contributing to a more sustainable and inclusive industry.
Originality/value
Traveling can present significant challenges for people with special needs, which affect the quality of their tourism experience. Despite growing academic attention to this issue in recent years, research in this field has primarily focused on specific aspects of disability. This study seeks not only to identify the barriers to travel faced by people with different special needs but also to explore the negotiation strategies used to overcome these barriers and the differences according to the type of special need.

Abstract
Organisational integration is being heralded as a critical “dynamic capability” and is seen as an important strategic issue for firms in the future. This study seeks to explore this issue in the specific context of e‐commerce and information system integration, by considering the model proposed by Poon and Swatman, in the case of small‐ and medium‐sized enterprises (SMEs) in the UK. Poon and Swatman propose that the model of business transformation enabled by traditional IT turns “inside out” when applied to the e‐commerce domain. Their model suggests a hierarchy of levels of e‐commerce integration. At the lowest level firms develop inter‐organisational systems. At the next level they undertake limited integration with existing internal systems, and only at the highest level do they achieve full internal integration. The study, which was carried out by a mailed questionnaire, found that the proposed model is indeed valid. Three distinct groups of firms are identified that correspond to the hierarchical levels proposed in the model. The benefits realised by the firms were found to increase with increasing integration, but the level of process change required was found to be independent of the level of integration. Contextual variables, such as industry sector and organisational size, are explored for firms at the three different levels of integration. Developments of the Poon and Swatman model are suggested.

Abstract
HARROGATE will be notable as the venue of the Conference in one or two ways that distinctive. The Association Year is now to begin on January 1st and not in September as heretofore; and, in consequence, there will be no election of president or of new council until the end of the year. The Association's annual election is to take place in November, and the advantages of this arrangement must be apparent to everyone who considers the matter. Until now the nominations have been sent out at a time when members have been scattered to all parts of the country on holiday, and committees of the Council have been elected often without the full consideration that could be given in the more suitable winter time. In the circumstances, at Harrogate the Chair will still be occupied by Sir Henry Miers, who has won from all librarians and those interested in libraries a fuller measure of admiration, if that were possible, than he possessed before he undertook the presidency. There will be no presidential address in the ordinary sense, although Sir Henry Miers will make a speech in the nature of an address from the Chair at one of the meetings. What is usually understood by the presidential address will be an inaugural address which it is hoped will be given by Lord Irwin. The new arrangement must bring about a new state of affairs in regard to the inaugural addresses. We take it that in future there will be what will be called a presidential address at the Annual Meeting nine months after the President takes office. He will certainly then be in the position to review the facts of his year with some knowledge of events; he may chronicle as well as prophesy.
