Purpose: Open Source software companies (OSSCs) are confronted with institutional pressures from Open Source software (OSS) communities. They must find an acceptable balance between the expectations of these communities and their own business model. However, there are still few studies that try to analyse the OSSC business models. The purpose of this paper is to highlight OSSC typical business models by using rich empirical data. Design/methodology/approach: The methodology is based on a combination of quantitative analysis of a sample of 66 OSSCs and qualitative analysis of three typical situations resulting from that sample. Findings: The quantitative study enables the authors to highlight three typical business models. The in-depth study of three typical cases enables the authors to specify these OSSC business models. The authors can distinguish four key dimensions: the relationship developed with the OSS communities, the strategic manoeuvres made, the key resources and competitive positioning. Research limitations/implications: The results indicate that it is possible for firms to accommodate both profit and non-profit logics using different strategic manoeuvres to position themselves with regard to the Open Source institutional environment. Such accommodation requires the development of key resources and the adoption of suitable competitive positioning. Practical implications: This study allows the authors to highlight two main practical contributions for OSSCs’ directors. First, the different manoeuvres identified may help them to ensure coherence between their strategic choices and the business model chosen. Second, the results can help OSSC founders identify value creation mechanisms more clearly by analysing four key variables. Originality/value: This paper provides new insight about OSSCs business models. It aggregates four dimensions that provide a more “fine-grained” analysis of business models, while other studies often emphasise one dimension (usually the regime of appropriability). © 2017, © Emerald Publishing Limited.

This article applies multiobjective optimization to show how the tradeoffs between cost and carbon emissions may be obtained in the context of sustainable operations. We formulate a model where transportation mode selection and order quantity decisions are considered jointly. We derive structural properties of the model and develop several insights. First, we show that switching to a greener mode of transportation while continuing to optimize the total logistics costs function may lead to a dominated solution. Second, we prove that the modal shift occurs only under strong carbon emissions reduction requirements. Third, we show that the efficient frontier is non-convex and we analyze some implications. Finally, we analyze the impacts of an increase in truck capacity. The results are illustrated through an example of a French retailer. © 2016 Springer Science+Business Media New York

The purpose of this paper is to investigate the cultural determinants of local subsidiaries' initiatives. An exploratory and qualitative research, conducted in a polish subsidiary in the telecommunication sector, indicated that the entrepreneurial culture of the subsidiary is not the unique cultural factor affecting local initiatives, as mentioned by several researches on this subject. Two main contributions emerge from this study. First, the corporate culture (for the multinational corporation), business culture and national are considered as barriers to local subsidiaries' initiatives. Second, these factors enhance subsidiaries capabilities and isolation while preventing the transformation of local initiatives into hybrid and/or internal ones. The implication is that this paper provides researchers and practitioners with an overview of the main cultural factors to take into consideration in order to exploit local subsidiaries' initiatives by the whole multinational corporation.

This article responds to the identified considerations and gaps in existing research on the way a new idea is transformed into a market-accepted new product. Utilizing the findings of an extensive theoretical analysis and empirical investigation on the subject, this research studies new product development within a wider strategic marketing context. The research interrelates three different perspectives: the process-defining perspective, that identifies and refines the managerial implications and theoretical considerations; the value-defining perspective, which investigates the various types and stakeholders of value; and the context-defining (contemporary consumer behavior and strategic marketing) perspective, which positions the entire innovation process within the comprehensive set of environmental and organizational processes and factors. The article concludes with the development of a preliminary Contemporary Strategic Framework for New Product Development. The framework answers the various theoretical considerations on the subject, incorporating the various processes' stages and interrelationships within a single descriptive system. In addition, it provides constructive functional managerial value through potential practical implementation and prescriptive interpretation. © 2012 Copyright Taylor and Francis Group, LLC.

Intermodal transportation is often presented as an efficient solution for reducing carbon emissions without compromising economic growth. In this article, we present a new intermodal network design model in which both the terminal location and the allocation between direct truck transportation and intermodal transportation are optimized. This model allows for studying the dynamics of intermodal transportation solutions in the context of hinterland networks from a cost, carbon emissions and modal shift perspective. We show that maximizing the modal shift is harmful for both cost and carbon emissions and that there is a carbon optimal level of modal shift. We also show that even if transportation cost and carbon emissions share the same structure, these two objectives lead to different solutions and that the terminal is located closer to the port when optimizing cost and further away when optimizing carbon emissions. The model also allows for studying the tradeoff between distance and volume, the impact of using aggregated models for estimating train transportation cost and carbon emissions as well as the potential policy measures that enable aligning cost and carbon emissions. © 2014 Elsevier B.V.

The aim of this paper is to lay emphasis on the main factors (economic, historical, structural, etc.) that affect Italian agri-food exports in the non-EU Mediterranean Partner Countries (MPCs). The authors estimate a gravity equation including some of the main variables found in the reference literature useful to highlight the main factors which influence the bilateral exchanges. The results show that the variables traditionally included in the gravity equation present the expected sign. In particular, Italian agri-food exports towards its neighbouring Mediterranean countries are positively affected by income of partner countries, colonial and historical ties, geographical proximity and the lack of importance of the agricultural sector in some partner countries.

In this paper, we present a novel model that generalise the steelmaking continuous casting planning and scheduling problem. The model includes three stages: converters namely CV, refining stands namely RS and continuous castings namely CC. The obtained problem can be formulated as a mathematical program with typical constraints, namely the times setup constraints. We develop a mixed integer linear program (MILP) to schedule several sequences of charges for more than two continuous castings devices. The aim is: (i) on one hand, to schedule a list of several sequences that are already ordered for each continuous casting with times setup between two successive sequences, (ii) on the other hand, to determine the optimal order of the successive sequences. We use a benchmark and randomly generated instances to test the model and solved by mean of the commercial software solver Cplex v12.5. These problems span a variety of instances varying from small to large sized instances with different intrinsec parameters as the availability date for a converter CV or the variation intervals of the start time for the first charge at the continuous casting CC stage. We analyse the efficiency of the proposed model based on the CPU time and show the time limitations of the model for large instances. Also, we show the robustness of the model when modifying the initial (starting) state. © 2014 Taylor & Francis.

For a geographical approach of convergence. Regional disparities in the European Union and their evolution.-The aim of this paper is to lay the conceptual and methodological foundations for a theory of economic convergence. Taking into account the spatial dimension when evaluating convergence is from this point of view an interesting perspective in the field of the geography. The index of local economic convergence proposed makes it possible to measure the simultaneous processes of economic convergence and divergence occurring in the European Union. By comparing the two periods 1995-2000 and 2000-2006 for all the European regions at the NUTS 23 level, it can be seen that there are situations of regions that have evolved in a favorable or unfavorable manner from the economic point of view. The spatial structure of these local economic convergence or divergence phenomena is very clear and reflects a true geography of the evolution of regional inequalities in the European Union. © Belin.
