Abstract
Purpose
The purpose of this study is to select the most appropriate city in Turkey for space shuttle launching ramp.
Design/methodology/approach
In the proposed approach, an integrated methodology is used. The SWARA method is used in the first phase of the solution for determining criteria’s importance weights. Based on the criteria weights obtained by the SWARA method, the WASPAS method is used for selecting the best alternative.
Findings
Mugla is selected for the most suitable city for the first space shuttle launching pad according to determined criteria and proposed model.
Research limitations/implications
Although there are 81 cities in Turkey, 4 alternatives were selected for evaluation. It is possible to eliminate this limitation by the future studies with the implementation of proposed model to entire of Turkey.
Practical implications
This proposed model can be used by the countries which want to have a new or first space shuttle launching ramp in the world.
Originality/value
Although some climatic conditions are pointed out on the location of the space shuttle launching ramp, in literature, there is not a comprehensive and detailed evaluation example as much as the model proposed in this study. Therefore, this study is the first in terms of the proposed model and applied techniques in the sectoral sense. In addition, the study is also a guide for solving the original model which is revealed in the selection of the most suitable alternative city for space shuttle launching ramp by different multi-criteria decision-making methods.

Abstract
TO say that the Twenty‐fourth S.B.A.C. Show was an unqualified success is perhaps to gild the lily. True there were disappointments— the delay which kept the TSR‐2 on the ground until well after the Show being one—but on the whole the British industry was well pleased with Farnborough week and if future sales could be related to the number of visitors then the order books would be full for many years to come. The total attendance at the Show was well over 400,000—this figure including just under 300,000 members of the public who paid to enter on the last three days of the Show. Those who argued in favour of allowing a two‐year interval between the 1962 Show and this one seem to be fully vindicated, for these attendance figures are an all‐time record. This augurs well for the future for it would appear that potential customers from overseas are still anxious to attend the Farnborough Show, while the public attendance figures indicate that Britain is still air‐minded to a very healthy degree. It is difficult to pick out any one feature or even one aircraft as being really outstanding at Farnborough, but certainly the range of rear‐engined civil jets (HS. 125, BAC One‐Eleven, Trident and VCIQ) served as a re‐minder that British aeronautical engineering prowess is without parallel, while the number of rotorcraft to be seen in the flying display empha‐sized the growing importance of the helicopter in both civil and military operations. As far as the value of Farnborough is concerned, it is certainly a most useful shop window for British aerospace products, and if few new orders are actually received at Farnborough, a very large number are announced— as our ’Orders and Contracts' column on page 332 bears witness. It is not possible to cover every exhibit displayed at the Farnborough Show but the following report describes a wide cross‐section beginning with the exhibits of the major airframe and engine companies.

Abstract
Purpose
On-ramp merging areas are typical bottlenecks in the freeway network since merging on-ramp vehicles may cause intensive disturbances on the mainline traffic flow and lead to various negative impacts on traffic efficiency and safety. The connected and autonomous vehicles (CAVs), with their capabilities of real-time communication and precise motion control, hold a great potential to facilitate ramp merging operation through enhanced coordination strategies. This paper aims to present a comprehensive review of the existing ramp merging strategies leveraging CAVs, focusing on the latest trends and developments in the research field.
Design/methodology/approach
The review comprehensively covers 44 papers recently published in leading transportation journals. Based on the application context, control strategies are categorized into three categories: merging into sing-lane freeways with total CAVs, merging into sing-lane freeways with mixed traffic flows and merging into multilane freeways.
Findings
Relevant literature is reviewed regarding the required technologies, control decision level, applied methods and impacts on traffic performance. More importantly, the authors identify the existing research gaps and provide insightful discussions on the potential and promising directions for future research based on the review, which facilitates further advancement in this research topic.
Originality/value
Many strategies based on the communication and automation capabilities of CAVs have been developed over the past decades, devoted to facilitating the merging/lane-changing maneuvers at freeway on-ramps. Despite the significant progress made, an up-to-date review covering these latest developments is missing to the authors’ best knowledge. This paper conducts a thorough review of the cooperation/coordination strategies that facilitate freeway on-ramp merging using CAVs, focusing on the latest developments in this field. Based on the review, the authors identify the existing research gaps in CAV ramp merging and discuss the potential and promising future research directions to address the gaps.

Abstract
THE Farnborough 1966 Show was at first glance much the same mixture as before, but the second glance was the more revealing. The participation in the flying display of European aircraft by no means swamped the air, even if the Italian verve took the acrobatic honours, but the theme of collaboration with other countries was to be found on practically every stand inside the exhibition tent. It was obvious that the smaller firms not directly involved in production agreements with other nations were very export conscious. The pacemaker of all this collaboration was of course the Concorde, only to be seen in model form, but rapidly taking shape at Toulouse and Filton, and many of the equipment manufacturers had Concorde hardware on display. Beagle announced the Pup, Britten‐Norman produced the production Islander, and Handley Page showed the Jetstream mock‐up. After many years of neglect, the industry is now taking an interest in the general aviation market. The P.1127 (R.A.F.) made its first appearance. The paradox of the P.1127 is that it is almost a part of Farnborough history, yet there is no other V/S.T.O.L. aircraft in the world that has but a fraction of the operating experience it has gained. Farnborough this year gave the impression of being more a serious trade show, and less a public spectacle. Sir Richard Smeeton, Director of the Society of British Aerospace Companies, reported that the exhibiting firms had received more serious business enquiries this year than ever before, and he forecast that 1968 would be a vintage year, which would see the appearance of the HS.801, the Concorde and Jaguar in the Farnborough skies. It is not possible to cover every exhibit shown at the Farnborough Show, but the following report describes a wide cross‐section beginning with the exhibits of the major airframe and engine companies.

Abstract
Purpose
As many of the next generation leaders are currently on college campuses, endorsing green buildings can foster environmental stewardship among the student body. However, marshalling in the social sphere of sustainability is also critical to cultivate more supportive and inclusive communities. With this in mind, a chief component of the social sphere within sustainability is equal opportunity. Relating equal opportunity to green campus buildings, the question presents itself: Do all campus users have accessibility to and within these green campus buildings from a social equity perspective?
Design/methodology/approach
To begin to answer this question, student team project deliverables were analyzed for building accessibility among a sample of Leadership in Energy and Environmental Design (LEED) buildings on the Blacksburg campus of Virginia Tech.
Findings
While findings suggest the vast majority of Americans with Disabilities Act (ADA) requirements are being met overall within the sample of LEED buildings at Virginia Tech and in some cases exceeded, recommendations are put forward to foster an even more inclusive campus environment.
Originality/value
While the literature shows that ecological sustainability and accessibility can be considered together, no studies were found focusing on accessibility of green certified campus buildings. This is an important area of study, as all members of the campus community deserve full access to campus buildings, especially LEED buildings that have been shown to have increased occupant benefits. This study begins to fill the gap by examining LEED certified buildings at the Virginia Tech campus in Blacksburg, VA through a student lens.

Abstract
Purpose
This paper aims to elaborate the concepts of boundary subjects and boundary objects in constructing and communicating relevant accounting facts for managing product development (PD). Boundary subjects as reflective actors benefit effective accounting enactment, by building a shared understanding about different actors’ roles and information needs, and by helping to respond to these needs with new boundary objects.
Design/methodology/approach
The paper uses a longitudinal interventionist case study of a machinery manufacturer. The focus of this case study was the production ramp-up phase at the end of a PD program. Different actors’ needs were first collected and elaborated by interventionist researchers (boundary subjects). Then accounting prototypes (boundary objects) provided new means of communication.
Findings
The findings show that dealing with boundaries is crucial in accounting development. The role of boundary subjects was fundamental in the process of choosing, constructing, elaborating and communicating accounting facts. During this process, accounting prototypes integrated new accounting facts, the boundary subjects mitigated the boundaries and the boundary objects focused and restricted communication about accounting facts.
Research limitations/implications
The paper tests the pragmatic constructivism approach by examining accounting enactment under uncertainty and ambiguity. The study refines pragmatic constructivism in terms of boundaries, boundary subjects as actors and boundary objects.
Practical implications
The intentional use of boundary subjects and objects as communication platform could push a more active inclusion of business controllers as active business partners.
Originality/value
The paper contributes to the literature on accounting development by highlighting the use of boundary subjects and boundary objects as fundamental mechanisms in constructing and communicating accounting facts.

Abstract
Purpose
This study aims to address policy, implementation and management, the three stages of inclusive open space. It compares both the level of design and implementation of open space in Beijing, Hong Kong and Taipei by following the inclusive guidelines. It also identifies recommendations for policy, implementation and management of inclusive open space and its facilities.
Design/methodology/approach
Field observations were conducted in 27 parks within three cities. In-depth interviews were conducted with a variety of participants, including visually impaired persons, government officers, representatives of non-governmental organisations, local communities and experts.
Findings
Most of the so-called inclusive environments and facilities have not been user-friendly in actual practice. The findings suggest that policies are an essential precondition; however, implementation and management must not be ignored because they ensure the effectiveness of inclusive design.
Research limitations/implications
Comprehensive and continuous studies on the proposed framework are recommended throughout the policy, implementation and management processes.
Practical implications
The findings serve as a reference and direction for taking a holistic approach to inclusive design of open space in densely populated cities.
Social implications
This study examines the levels of inclusive open space and illustrates how to provide barrier-free environments that can be used by the widest spectrum of people.
Originality/value
This study evaluates policy, implementation and management in the three cities based on 29 guidelines generated from seven principles of inclusive design. A research framework is proposed for researchers and policymakers to consider how to achieve effective inclusive open spaces.

Abstract
Purpose
The Internet of Things (IoT) real-time data collection can help to more efficiently optimize and control companies' internal processes. Prior research analyzed IoT benefits and potential applications. Nevertheless, there is little empirical evidence and theoretical understanding of how IoT impacts new product development (NPD). This article aims at narrowing this gap.
Design/methodology/approach
In total, 54 case studies were selected from an IoT database – IoT ONE. IoT ONE has a section on NPD. NPD was divided into three phases: discovery, development and commercialization. The adopted IoT technology maturity level was also analyzed. A content analysis was carried out to identify the impacts of IoT in NPD.
Findings
This study’s findings capture the emerging patterns of IoT adoption and its impact on NPD. Of the total, 33 IoT adoption cases in the sample were in the machinery and equipment sector. Adopted technologies were at least two years old in 85% of the sample. Only 15% adopted cutting edge technologies (less than 2 years old). Key actors (e.g. vendors) facilitate IoT adoption. By a small margin, the larger impacts of IoT were in the commercialization phase, where it was primarily applied to improve and optimize production processes, to better execute and synchronize new products launching, and to increase the factories' productive capacity. In the discovery phase, IoT was mainly used to identify new opportunities in the market and to collect customer data, to generate a better customer experience. In the development phase, IoT allows greater integration across departments, increasing internal collaboration and allowing more flexible NPD.
Originality/value
Many articles studied the impact of information technologies in NPD. Few address the impact of IoT in NPD. IT tells about the impact of better communications with relevant people. IoT tells about machine acquired information and knowledge. This is new, much broader and deals with quite different impacts on NPD.
