    Procurement of Railway Infrastructure Projects - A European Benchmarking Study2017Ingår i: Civil engineering journal -Tehran, ISSN 2476-3055, Vol. 3, nr 4, s. 199-213Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This benchmarking study compares how railway investments are procured in five European countries: Sweden, Norway, Germany, the Netherlands, and the UK. In total, 19 procurement managers and project managers were interviewed. This study compares the national rail clients' procurement strategies regarding: delivery system, reward system, contractor selection, and collaboration model. Historically, these clients have used in-house production. The first step towards a gradually increased usage of the market was to outsource the construction activities while keeping the design and development competence in-house. All five countries have mainly used Design-Bid-Build contracts in their initial outsourcing. However, the last few years there is a discernible trend in Sweden, Norway, the Netherlands and the UK towards allocating more design and development responsibilities to contractors (i.e. Design-Build contracts) and increasing the strategic focus on cooperation. The UK and the Netherlands are forerunners in this trend that can be viewed as a third step in the transition towards a market oriented railway sector. Norway and Sweden is in the middle of this transition, whereas Germany has not initiated this change. The transition towards a gradually increased usage of the market has two main dimensions; degree of cooperation and degree of contractor freedom, which differs among the countries. The UK and Sweden focus on increasing both these dimensions, while The Netherlands and Norway mostly focus on increasing the degree of contractor freedom. Germany still limits both dimensions by performing design and development in-house and letting contractors compete for construction work in Design-Bid-Build contracts. Due to historical and cultural reasons, Deutsche Bahn in Germany is very hesitant to engage in collaboration with external suppliers; focusing on competition is considered more appropriate and less controversial.

    Collaborative procurement strategies for infrastructure projects: a multiple-case study2019Ingår i: Proceedings of the Institution of Civil Engineers: Management, procurement and law, ISSN 1751-4304, Vol. 172, nr 5, s. 197-205, artikel-id 1900016Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    With the announcement to tender a project, several strategic decisions are made that have significant impact on the innovation and efficiency potential of a project. The purpose of this study is to investigate and compare how different types of integrative and collaborative procurement strategies may enhance the opportunities for improved efficiency and innovation in infrastructure projects. Hence, it contributes to the scientific debate on buyer-supplier relationships in relation to project performance. Furthermore, it guides public client organisations in steering explicitly for integration and innovation in their projects. Interview-based case studies of ten public infrastructure projects procured based on four different types of collaborative procurement strategies in Sweden and the Netherlands were conducted. The findings indicate that the duration of the collaboration is fundamental in setting the limits for innovation and that early involvement and long-term commitments in maintenance open up opportunities for more innovation. Naturally, the potential for increased efficiency is higher than for innovation and also occurs in collaborations with limited duration. The findings confirm the importance of a learning perspective on procurement strategies for public client organisations and show the importance of explicit considerations on incentives and project governance issues in the front-end phase of a project.

    Public procurement for carbon reduction in infrastructure projects: an international overview2019Ingår i: Proceedings SBE19 Graz Sustainable Built Environment Conference 2019: Transition towards a net zero carbon built environment, IOP Publishing , 2019, Vol. 323Konferensbidrag (Refereegranskat)
    Abstract [en]

    Carbon emissions emanating from infrastructure construction projects are substantial and stem primarily from production of construction materials and use of energy for construction transport and site activities. In recent years, public infrastructure clients world-wide have begun to include carbon reduction goals in their procurement requirements. This is however a new and complex field where practices vary and are still developing. In this paper, we compare models for carbon reduction requirements in infrastructure construction projects based on case studies of large projects in Australia, USA, the Netherlands, Sweden and UK. We found that open, functional carbon reduction requirements were considered innovative but entailed costs for calculating baselines and risks for speculation. Also, high time pressure in projects limits contractors' opportunities to explore reduction opportunities. Thus, specific, prescriptive requirements may play an important role in client-led, long-term innovation processes. Organizational competence and resources on the buyer side are essential, and policies for carbon reduction should aim to increase client capacity. Further, procurement practices are developed in mutual interaction between clients and suppliers over longer periods of time, which limits possibilities to transfer procurement policies and requirements between contexts.

    Designing and implementing procurement requirements for carbon reduction in infrastructure construction–international overview and experiences2020Ingår i: Journal of Environmental Planning and Management, ISSN 0964-0568, E-ISSN 1360-0559Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Carbon emissions emanating from infrastructure construction are substantial, and public infrastructure clients have begun to include carbon reduction goals in their procurement requirements. This is a new and complex field where practices vary and are still developing. Based on project documentation and interviews we map and analyze the design and implementation of carbon reduction requirements in projects by leading infrastructure clients in Australia, the Netherlands, Sweden, the US and the UK. Procurement requirements were influenced by concerns for tender competition, transaction costs and innovation, and further adapted to project delivery models, market maturity and client capabilities. Increasing awareness of practical and contextual constraints often led to modified strategies. This paper identifies factors that should be considered when designing carbon policies and requirements. This knowledge is important for clients and governments in order to develop more effective strategies for learning between contexts. Policies and future research should address client capabilities to drive long-term innovation.

    Procurement Requirements for Carbon Reduction in Infrastructure Construction Projects: An International Case Study2019Rapport (Övrigt vetenskapligt)
    Abstract [en]

    Executive Summary

    Introduction

    Following alarming reports from the IPCC, climate change has engaged policymakers world-wide to chart policies at different administrative levels to mitigate increasing greenhouse gas emissions. The construction sector causes a substantial part of all greenhouse gas emissions, primarily carbon dioxide. Traditionally in this sector, the focus of carbon reduction measures has been on improving the energy efficiency of buildings. Further, various sustainability assessment schemes (BREEAM, LEED, Green Star, etc.) have been developed to assess sustainability performance. More recently, awareness has increased of the considerable greenhouse gas emissions arising from the manufacturing of construction materials and components, and also from construction processes and transport. Consequently, the infrastructure construction sector is now considered as a major source of greenhouse gases. In the UK, The Infrastructure Carbon Review has estimated that the construction, maintenance and operations of infrastructure assets account for 16% of the nation’s total carbon dioxide emissions. It is widely acknowledged that these emissions need to be significantly reduced if the international and national reduction targets are to be met.

    About the project

    This research project has investigated the institutional and organisational contexts, policies, procurement requirements and implementation strategies used to drive greenhouse gas reduction in large infrastructure projects in five countries world-wide: Australia, The Netherlands, Sweden, the UK and the US (see below for an overview of case study projects). The study is based on interviews with key partners on the client side and in the supply chain of each project. To provide a contextual understanding of the strategies used in these projects, we further include descriptions of the policy background that underlies current strategies and ambitions. Thus, the project traces the pathway from political and organisational goals to actual realisation in projects.

    The title of this research project is Implementation of procurement requirements for sustainable collaboration in infrastructure projects, also referred to as Impres. The project is a collaboration between the engineering consultancy firm WSP, the KTH Royal Institute of Technology in Stockholm, Lund University and the construction company Skanska. The project is co-financed by Construction Climate Challenge (CCC), a sustainability research fund and network initiated by Volvo Construction Equipment, and the Swedish Research Council Formas. The latter funding comes through a grant for the Strong Research Environment ProcSIBE, Procurement for Sustainable Innovation in the Built Environment[1].

    We expect that results from this research project will be useful for decision-makers on the client side that are in charge of developing policies, procurement strategies and procurement requirements to reduce carbon emissions in the construction sector. Further, client and contractor project managers, environmental specialists and procurement staff responsible for implementing policies will be interested in experiences gained in similar initiatives in other countries. In parallel with this report, scientific articles are being developed by the authors to analyse and discuss the results described in this report more thoroughly in relation to other studies and to theory.

    Conclusions

    In all countries studied, there is an ongoing process to develop and implement policies for carbon reduction in infrastructure projects, with raised ambitions over time. In some cases, the development has initially been driven by a few dedicated individuals, but today there are frameworks and executive mandates in place that would make it hard to avoid carbon reduction commitments. National and regional reduction policies were found to be important in encouraging clients to develop ambitious carbon requirements that can contribute to setting new industry standards.

    Carbon reduction measures such as optimisation of constructions, minimised transport, reuse of excavated material and cement clinker replacement are applied in the studied cases. However, most of these measures are also cost efficient and would – or should – have been undertaken in a normal design and construction optimisation process. The positive side of this is that considerable carbon reductions may be achieved within existing budgets, and in most cases will even reduce cost, and that an increased focus on carbon may contribute to finding more such options. However, it also raises the question of what constitutes a relevant reference case, or baseline. Further, to meet the target levels of the Paris agreement, costly measures will also be needed, and this research identified only a few examples of such policies being implemented. 

    Goals for carbon reduction are still new to many in the sector, and both clients and industry partners need time to adjust and develop new competencies. In countries with a longer history of carbon management, procurement strategies and requirements have advanced through continuous interaction between clients and industry actors over longer periods of time. Clients are wary of introducing requirements that may limit competition, and requirements to comply with rating schemes or to supply EPDs have been introduced successively to match the development of industry capacity. Award (MEAT) criteria related to carbon are used, but more often to increase awareness of carbon reduction rather than as a substantive basis for selection. Front-runner contractors and material suppliers were found to play important roles in reducing obstacles to innovation-oriented procurement. Moreover, the development of procurement requirements has been aligned with information and training initiatives, tool kits and guidelines to support low-carbon design and the calculation of emissions. In general, client environmental specialists have taken an active part in supporting the implementation of requirements in supply chains.

    Procurement requirements are considered important in driving carbon reductions in all countries, but the preferred style of these requirements vary. This diversity was partly related to general carbon management maturity and partly to general contracting practice and policy culture in the country or region. All countries used some form of contract-level reduction requirements, in most cases set in relation to a carbon emissions baseline. Overall, reduction requirements are perceived to encourage innovation, but our results show that such requirements were often more complex than foreseen and associated with administrative costs. First, to produce change and avoid speculation it is important to set requirements and incentives at the right level, which requires awareness on the client side of both the supplier’s competence and of the opportunities for carbon reduction in the specific project. Also, sharp requirements call for equally sharp and transparent performance evaluation. Moreover, much time was spent on calculation and re-calculation of baselines which could detract from measures for actual reduction of carbon emissions. In effect, time constraints in the projects limited the opportunities to involve subcontractors and material suppliers, which meant that all possible reductions were not realised. We conclude that expectations for substantial and innovative carbon reductions through functional reduction requirements may be too high. To influence sub-contractors and suppliers directly, several clients use specific requirements.

    Collaborative contracting models are a flexible option to encourage innovation and integrate knowledge of different participants. Many interviewees state the importance of breaking silo-thinking and integrating the supply chain in order to reach greater carbon reductions. Also, long-term alliances allow for continuous learning and more transformational innovation, including incentivising contractors to find ways of fulfilling client goals while building less. However, it should be emphasised that strong client leadership and commitment are essential both to legitimise collaborative contracting models and to achieve more fundamental behavioural change within collaborative projects and alliance schemes.

    Clients in mega-projects perceive an obligation to conform to national policy goals and may also have ambitions to be industry-level change agents. Since such projects have vast budgets, last for long periods of time and engage highly competent firms and individuals, they are often expected to show high performance in the area of innovation. However, mega-projects have many goals to fulfil, are technically and organisationally complex and associated with high risks. Therefore, time and willingness to develop new ways of working or implement new technology may be lacking. Further, even large projects may not be long enough to encompass processes to develop, test and approve new solutions. Thus, to support more efficient innovation processes in the industry, a long-term system perspective is needed. Interviewees suggested using smaller pilot projects for quicker testing of new materials, tools and technologies and, once proven, use procurement requirements in large projects to implement these more widely in the market.

    Overall, the study shows that the applicability of procurement requirements for carbon reduction is dependent on how well these requirements are aligned with culture, policies and capabilities in the local context. Inspiration may be sought from cutting-edge examples in other countries and regions, but practices may seldom be directly transferred. Also, it is clear that awareness, competence and capacity on the buyer (client) side is a key success factor. Such client capabilities involve constructive collaboration between procurement functions, environmental specialists and project managers. Further, policy makers need to acknowledge that measures to reduce carbon must align with existing procurement and innovation systems. To reach higher levels of ambition for carbon reduction, such institutional structures may also need to be changed.

    Recommendations

    Based on the findings, our recommendations to the target group of policy-makers and clients are:

    Policy level – national, regional and organisational

    • ·         Set high-level goals and policies for carbon reduction in order to sanction ambitious initiatives that contribute to setting new industry standards.
    • ·         To reduce barriers for innovation-oriented procurement requirements, engage industry associations and encourage initiatives by supply-side front-runners.
    • ·         When developing organisational policies and strategies, address not only ambitions but also what roles the client and other parties should have in implementation.

     

    Project level policies and procurement requirements

    • ·         When defining requirements, consider implementation costs for setting and following up requirements. In particular, be careful that focus stays on carbon mitigation measures and that calculation of baselines does not impact negatively on carbon management. Assess and mitigate behavioural risks associated with incentives.
    • ·         Ensure that requirements will be effective in influencing all relevant decision-makers in the supply chain (designing engineers, constructors and material suppliers). This implies that time, competence and resources should be available at relevant points in time.
    • ·        Apply a long-term learning perspective and acknowledge that different combinations of award and selection criteria, reduction requirements, specific requirements and rating schemes may be preferable over time.
      • ·         Align requirements and activities with general contracting models and encourage models that enable integration of knowledge and carbon management in the supply chain.

     

    Innovation and learning

    • ·         Develop guidelines, tools and training programs to help build industry capabilities.
    • ·         Establish which organisations should drive development, for example commission, host and update guidelines, and provide training and support.
    • ·         Communicate plans for raised ambitions well in advance, for example requirements to comply with established carbon management standards and rating schemes.
    • ·         Orchestrate long-term innovation by combining small pilot projects to test new solutions with systematic implementation in larger projects to achieve wide market dissemination. 
    • ·         Establish transparent procedures for updating client standard specifications based on frontrunner initiatives, planned pilots and academic research.
    • ·         Innovation should also address contracting and business models: develop institutional capabilities that enable and legitimise long-term, strategic collaborative alliances.

    Innovation outcomes and processes in infrastructure projects–a co mparative study of Design-Build and Design-Build-Maintenance contracts2022Ingår i: Construction Management and Economics, ISSN 0144-6193, E-ISSN 1466-433X, Vol. 40, nr 2, s. 142-156Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Innovation is often seen as essential for long-term development in the construction industry, but its actual outcomes and processes in construction projects require more attention. Many studies on procurement strategies and delivery systems have focussed on the public transport infrastructure sector, whereas most construction innovation scholars have addressed the innovation phenomenon in construction generally. Thus, the purpose of this study is to compare how two delivery systems, design-build (DB) and design-build-maintenance (DBM), influence project-level innovation. Findings are based on empirical data from a multiple case study of six infrastructure projects, three with DB contracts and three with DBM contracts, in which 12 innovations are identified, described, and compared. The findings show that various kinds of innovations in terms of outcomes and processes are implemented in infrastructure projects, and that the delivery system do effect both dimensions. Long maintenance responsibilities tend to spur contractors to engage in early exploration of sustainable solutions that could be of long-term benefit. The research contributes to procurement literature by exemplifying how delivery systems influence both the outcomes and processes of project-level innovations. It also increases our knowledge about construction innovation as a multi-dimensional phenomenon.

    Circular Public Procurement through Integrated Contracts in the Infrastructure Sector2021Ingår i: Sustainability, E-ISSN 2071-1050, Vol. 13, nr 21, s. 11983-Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Public clients’ procurement strategies are central in facilitating innovation towards sustainability. In the infrastructure sector, the three main project activities—design, production, and maintenance—are traditionally not procured in an integrated way, which results in sub-optimizations and a lack of life cycle perspective. As project actors are accustomed to traditional, non-integrated forms of contract, implementing integrated contracts imposes fundamental changes to the interdependencies among actors, resources, and activities. This study analyzes the interfaces among key project actors and the related interdependencies across design, production, and maintenance in Design–Build–Maintain contracts, and initiates a discussion on how to manage these interdependencies when implementing integrated contracts. This study of circular public procurement (CPP) focused on three infrastructure projects using integrated contracting and applied the industrial network approach (INA) to analyze interdependencies in how they may influence innovation and sustainable development. The study found significant obstacles to clients obtaining the benefits of integrated contracting and concludes that understanding interdependencies is necessary to implement integrated contracts successfully. The study contributes to the construction management literature by adapting the INA to contracting, and to the CPP literature by providing empirical evidence of sustainability and circularity in infrastructure projects.

    Sustainable Public Procurement in Large Infrastructure Projects—Policy Implementation for Carbon Emission Reductions2021Ingår i: Sustainability, E-ISSN 2071-1050, Vol. 13, nr 20, s. 11182-11182Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The infrastructure construction sector is a significant source of carbon emissions, and more stringent procurement requirements are central to meeting reduction targets in this demand-led and project-based industry. This paper aims to analyze the implementation of international policies for reducing carbon emissions in infrastructure construction, focusing on the interaction between policy ambitions and procurement practices. Based on case studies of large projects and their contexts in five countries worldwide: Australia, the Netherlands, Sweden, the UK, and the US, a cross-country comparison is performed of how policies and practices for carbon reduction develop across multiple implementation levels. Three levels are included in the analysis: policy, industry, and project level. We identify the projects as either drivers of policy goals, frontrunners in industry-level development processes, or translators of national policy. These roles, and the associated pathways for carbon emission reduction, are context-specific and depend on the policy ambitions at the national or regional level, the maturity of the supplier market, and, often, on the strategies of individual champions at the project level. Long-term learning processes, both within and between the various levels, are essential for advancing carbon reduction.

    Implementation and management of a circular public procurement contract for furniture2023Ingår i: Frontiers in Sustainability, E-ISSN 2673-4524, Vol. 4, artikel-id 1136725Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Circular public procurement (CPP) is one way to increase sustainability and circularity in public spending. As previous research focuses primarily on procurement, more insight is needed on the latter stages CPP. Real-life examples of CPP implementation are also required to promote the concept to practitioners, improve governance, and add depth to the literature. This study, therefore, provides in-depth knowledge of CPP implementation and management by analyzing a case of circular furniture flows and its implications for the procuring organization. The focus on furniture is motivated by the large volumes sent to landfills every year despite its remanufacturing potential, as well as the large environmental impact for production, a potentially long lifetime, and an often-high purchasing price. The results show that strategic decisions to prioritize sustainability are necessary when resource efficiency and cost reductions do not align in a short-term perspective. A more centralized governance structure facilitates decisions on reuse, remanufacturing and disposal in an organization, e.g., coordination of products for remanufacturing, pooling products for reuse, and standardization of design choices. Follow-up and inventory systems are crucial tools for integrating previously installed products with CPP, keeping track of circular flows, and providing feedback to improve subsequent procurements. Crucial elements in the follow-up include adaptation to circularity in the economy system and accounting for the prolonged life and reuse of furniture. The study's results emphasize how an organization's prerequisites play an essential part in the implementation of CPP and that contextual solutions are needed for circular challenges. The study contributes to the fields of policy implementation, CPP, and the use of circular business models in a public context, as well as to the less explored field of procurement in a circular economy context. Suggestions for future research include studies on product categories with other environmental impact profiles, and on waste management regulations that can make or break circular systems.

    Circular indicators for the design and procurement of plastic products in the healthcare sector - A review2024Ingår i: 31st CIRP Conference on Life Cycle Engineering, LCE 2024, Elsevier B.V. , 2024, Vol. 122, s. 891-896Konferensbidrag (Refereegranskat)
    Abstract [en]

    A critical shift is required to meet the challenges reflected in the sustainable development goals. Policymakers in the EU are betting on a transition from a linear to a circular economy to make this happen. Public procurement is vital in this context, e.g., accounting for 20% of Swedish GDP, with circular public procurement being critical to the transition. Until now, the research focus in this area has been narrower, concentrating on, e.g., IT equipment or furniture. However, plastic medical products have not been addressed despite generating substantial environmental impact and offering a tremendous upside. To enable the application of circular economy strategies in this context, changes are required on two ends: the design of the products and the criteria under which the products are procured. Indicators are the central basis of decision-making in any purchasing decision and are considered powerful enablers and drivers of the transition to a circular economy. This paper reviews circular indicators as a starting point toward guidelines for the circular design and procurement of plastic products in the healthcare sector. Based on this, critical factors for developing a comprehensive indicator for the design and procurement of circular plastic medical products are identified.

    Is the pace of technology development a threat or opportunity for sustainability?: the case of remanufactured industrial robots2018Ingår i: Procedia CIRP, Elsevier B.V. , 2018, s. 247-252Konferensbidrag (Refereegranskat)
    Abstract [en]

    Remanufacturing has been identified as having much potential and providing a wide range of benefits. However, challenges remain for remanufacturing to be widely accepted, both from customers as well as within industrial firms. Business models for remanufacturing are complex and remanufacturing requires multiple competences across the firm. This paper is a study of the remanufacturing market for industrial products and is exemplified by a case study of a leading robot company in the US market. The study shows that rapid technology development impacts the remanufacturing possibilities and as such has an impact on sustainability. Technology development can be seen as a threat to remanufacturing e.g. making products become obsolete as well as leading to compatibility problems where it is difficult to find spare parts. Technology development also results in cheaper robots, making it difficult to provide economic incentives to buy remanufactured products. However, fast technology development can also be a possibility to firms that have well developed remanufacturing processes, as they are able to adjust to newer technologies. The study also points to the importance of cross-functional collaboration in the design phase of products, where remanufacturing needs to be considered. The article provides implications on how to manage rapid technology development in remanufacturing.

    Sustainable public food procurement: actors’ role and influenceManuskript (preprint) (Övrigt vetenskapligt)
    Abstract [en]

    This study examines the interpretation and incorporation of sustainability in public foodprocurement by interviewing stakeholders, such as procurement officers, wholesalers, chefs,and food producers. Findings highlight a consensus on the need for sustainability measures,such as purchasing local and organic products, but disagreements on the most influentialactors in the process. The influence of system-level factors, including market dynamics andregulatory frameworks, plays a significant role in implementing sustainable procurement.There is trust in the organic label and locally sourced products, yet actors require furtherpractical examples and hands-on solutions to facilitate their work towards a more sustainablefood system for the future.

    Sustainable public food procurement: criteria and actors’ roles and influence2024Ingår i: Frontiers in Sustainable Food Systems, E-ISSN 2571-581X, Vol. 8, artikel-id 1360033Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Food production and consumption significantly contribute to climate change. The public sector, which procures large quantities of food, has a crucial role in steering toward more sustainable food systems. More empirical studies involving practitioners are called for to understand the complexity of sustainable public food procurement. This study examines how actors interpret and implement sustainability in food procurement, as well as their influence on this process. A comprehensive analysis of multi-actor collaboration and stakeholder engagement involving interviews with key actors such as procurement officers, wholesalers, chefs, and food producers is presented. Findings highlight a consensus on the need for sustainability measures, such as purchasing local and organic products. The results showcase the potential transformation of power dynamics within the supply chain in response to modifications in procurement standards toward local produce and the overuse of product-specific criteria. However, assuming that local is invariably sustainable carries the risk of falling into the “local trap” when the consequence of procuring local varies and requires further investigation. The influence of system-level factors, including market dynamics and regulatory frameworks, plays a significant role in implementing sustainable procurement, as well as alignment and coordination in the supply chain.

    Cost–benefit analysis of beach-cast harvest: Closing land-marine nutrient loops in the Baltic Sea region2022Ingår i: Ambio, ISSN 0044-7447, E-ISSN 1654-7209, Vol. 51, nr 5, s. 1302-1313Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Harvesting beach-cast can help mitigate marine eutrophication by closing land-marine nutrient loops and provide a blue biomass raw material for the bioeconomy. Cost–benefit analysis was applied to harvest activities during 2009–2018 on the island of Gotland in the Baltic Sea, highlighting benefits such as nutrient removal from the marine system and improved recreational opportunities as well as costs of using inputs necessary for harvest. The results indicate that the activities entailed a net gain to society, lending substance to continued funding for harvests on Gotland and assessments of upscaling of harvest activities to other areas in Sweden and elsewhere. The lessons learnt from the considerable harvest experience on Gotland should be utilized for developing concrete guidelines for carrying out sustainable harvest practice, paying due attention to local conditions but also to what can be generalized to a wider national and international context.
