Only recently have historic concrete buildings received attention and the need for their protection has been understood. Their listing as architectural heritage in most countries is ruled by legislations. The research carried out within the framework of the CONSECH20 JPI project on the conservation of historic concrete buildings in the Czech Republic, Cyprus, Italy and the Netherlands has allowed to study the legislations in the four aforementioned countries and how these are brought to practice. This paper aims at the evaluation of these legislations and of their function in practice.

The legislations have been examined focussing on the protection of historic buildings and the guidelines to achieve a correct technical conservation. These were assessed in practical situations. The situations of the four countries were studied and the parameters used allowed comparisons.

Concrete buildings are at risk and the guidelines should be further developed to meet actual conservation needs, including historical and aesthetical compatibility. The re-use of listed concrete buildings often means transforming and adapting these to a variety of modern needs and norms: the complexity of this assignment asks for a multidisciplinary teamwork. The bottom-up Dutch programme for quality in conservation, striving to bring ethical and technological principles to practice, could be a sound basis for developing respectful conservation strategies of heritage concrete buildings.

The research concerns the four countries involved in the CONSECH30 project and could be extended to include more countries.

More stakeholders have to be involved in the process of conservation and transformation of heritage concrete buildings. This should be directed by the legislation.

No direct social implications are foreseen from the outcome of the research. However, the suggestion is made that social involvement is essential in planning concrete building transformations.

The study focussed on the application of theory (the legislation) to practice (thus showing the limits of the legislation), which is an innovative way of contributing to the conservation of historic concrete buildings.

Toyota had mature lean capabilities when developing its supplier network. This paper aims to explore how companies can develop a Toyota-style supplier network (TSN) while their lean capabilities are still evolving.

Theoretically, this paper relies on the literature on lean maturity levels and lean supplier network development. Empirically, the paper portrays a Toyota-style initiative, detailing the buyer’s efforts to develop internal lean capabilities concurrently with developing lean in its supplier network. It compares the Network for supplier innovation (NSI) initiative with TSN development regarding activities, organizations and knowledge-sharing routines.

Unlike the sequential development in the case of Toyota, NSI improved performance and capabilities in the buyer’s supplier network by implementing lean in the firm and its supplier network concurrently. Third-party involvement was the key to the initiative’s success.

The findings are based on an in-depth single-case study which allows theoretical generalization but not statistical generalization. Furthermore, the case study concerns an initiative with Norwegian firms during a financial recession. Future studies should consider these limitations on how firms with evolving lean capabilities can develop a TSN-style supplier network and the importance of involving third parties operating in the role of lean master.

This study suggests what buying firms should consider when designing a TSN initiative, enrolling suppliers and engaging third parties that can take on the role of lean master.

Previous research has focused on how mature lean firms develop lean suppliers and networks. This paper extends this to firms whose lean capabilities are still evolving.

The aim of this study is to explore which factors of entrepreneurship and innovation influence economic development under the quadruple helix model, contrasting Southern and Northern Europe.

In this study, secondary data are collected from the Global Entrepreneurship Monitor databases, Organization for Economic Co-operation and Development and Global Competitiveness Index, for four countries in the North and four Southern European countries, for the period from 2007 to 2015. Data was analyzed with SPSS 22.0 software and subjected to several multivariate statistical tests.

The results show a statistically significant difference in the variables of the four quadruple helix model dimensions. This means that Northern European countries (Finland, the Netherlands, Norway and Sweden) display better results on innovation and entrepreneurship than Southern European countries (Spain, Greece, Italy and Portugal). The results also showed that per capita gross domestic expenditure on R&D is positively related to government and university dimensions, with significant differences between Southern and Northern European countries.

It is hoped that this study will contribute to new evidence on the factors of innovation and entrepreneurship that are decisive for economic development. To the traditional quadruple helix model, control variables were added to meet the endogenous characteristics of the countries.
