Abstract

Purpose

Previous research shows that implementing lean construction is not a straightforward task. The purpose of this paper is to examine the role of formal and informal mechanisms in implementing lean principles in construction projects.

Design/methodology/approach

The paper draws on a single case study of the implementation of innovative lean principles in a public construction project in Norway. The study is based on qualitative data, including 17 semi-structured interviews with 21 individuals, document analysis, and observations in meetings and seminars, in addition to informal conversations.

Findings

Formal mechanisms, including contractual arrangements, have the potential to both facilitate and hamper the implementation of innovative lean principles in a construction project. They might create coherence, but at the same time they might limit the scope of the concept in such a way that others do not accept it. Informal mechanisms, including social and lateral relationships and trust aid implementation, both directly by creating commitment and by modifying the challenges that the formal mechanisms potentially incur. Formal mechanisms may, in turn, nurture the informal ones.

Research limitations/implications

The research is based on a single case study within the Norwegian public sector, which is dependent on specific public procurement regulations and subject to strong contractual traditions.

Originality/value

The research extends the existing knowledge of implementation of lean construction in the construction industry. It helps refining the understanding of the role played by formal and informal mechanisms, and the interplay between them in the implementation process. This knowledge is also relevant for process innovations in construction in general.

Abstract

Purpose

The purpose of this paper is to review ontologies and data models currently in use for augmented reality (AR) applications, in the cultural heritage (CH) domain, specifically in an urban environment. The aim is to see the current trends in ontologies and data models used and investigate their applications in real world scenarios. Some special cases of applications or ontologies are also discussed, as being interesting enough to merit special consideration.

Design/methodology/approach

A search using Google Scholar, Scopus, ScienceDirect and IEEE Xplore was done in order to find articles that describe ontologies and data models in AR CH applications. The authors identified the articles that analyze the use of ontologies and/or data models, as well as articles that were deemed to be of special interest.

Findings

This review found that CIDOC-CRM is the most popular ontology closely followed by Historical Context Ontology (HiCO). Also, a combination of current ontologies seems to be the most complete way to fully describe a CH object or site. A layered ontology model is suggested, which can be expanded according to the specific project.

Originality/value

This study provides an overview of ontologies and data models for AR CH applications in urban environments. There are several ontologies currently in use in the CH domain, with none having been universally adopted, while new ontologies or extensions to existing ones are being created, in the attempt to fully describe a CH object or site. Also, this study suggests a combination of popular ontologies in a multi-layer model.

Abstract

Purpose

The purpose of this paper is to analyse the economic benefits of short sea shipping (SSS) in the shape of Motorways of the Sea (MoS) compared to road transport. The study cover a gap in agro-food economics and analyses the economic benefits of sea transport mode compared to road transport in the food trade between Spain and Italy for a specific product: olive oils.

Design/methodology/approach

Three different transportation scenarios are considered (road only, road combined with accompanied SSS and road combined with unaccompanied SSS) linking the main olive oil production and consumption areas in Spain and Italy. In each scenario the cost per unit shipped have been calculated.

Findings

The results show the road option is about 30 and 34 per cent more costly than the best SSS option available for the exportations from Jaén and Southern Catalonia, respectively.

Research limitations/implications

The need of further research is identified, mainly focused in two directions: first, the need for inclusion of new variables to the model (e.g. value of time, seasonality, complexity of the transport chain, potential demand, etc.) to better assess the competitiveness of the sea connection and, second, a study of the environmental impact and socio-economic benefits of SSS implementation for the agri-food sector.

Originality/value

The research enriches the current literature on this field and provides a basis for future studies. In particular, it corroborates the strategic decisions taken in the framework of European transport policy demonstrating a greater economic sustainability of SSS, and more specifically MoS, compared to the road transport.
