The network perspective and the internationalization of small and medium sized software firms from Syria

This study has employed a case-based approach to explore the relevance of relational factors in explaining the internationalization of six software B2B SMEs from Syria. It contributes by providing rare empirical insights on the internationalization behavior of Middle Eastern SMEs and redressing, albeit slightly, the apparent research gap in the internationalization of knowledge-based SMEs from developing countries. Analysis results suggest the importance of the relational perspective in explaining the initial internationalization, market selection and internationalization speed of the investigated software firms. It emerged that the case firms either reacted to the cross-border opportunities offered by their relational contacts or proactively pursued overseas opportunities through existing and newly developed relationships. Their market entry decisions and internationalization pace also appear to have been influenced by these relationships. Both social and business networks were found to be important, but social ties seemed more influential at initial stages, with business networks becoming more dominant subsequently. The article concludes with appropriate recommendations for managerial decision making and future research.     

The Open Innovation Journey: How firms dynamically implement the emerging innovation management paradigm

Open Innovation is currently one of the most debated topics in management literature. Nevertheless, there are still many unanswered questions in Open Innovation research. Especially two issues require further investigation: (i) understanding the relevance of Open Innovation beyond high-tech industries and (ii) studying how firms implement Open Innovation in practice. The paper addresses these topics by studying, through an in-depth case study, the journey that the Italian leading cement manufacturer, has undergone to move from a Closed to an Open Innovation paradigm.The paper shows that the Open Innovation paradigm is implemented along a three-phase process that comprises the stages of unfreezing, moving and institutionalising. Moreover, it emerges that the changes through which Open Innovation has been implemented involve four major dimensions, i.e. networks, organisational structures, evaluation processes and knowledge management systems. They should be therefore conceived as the managerial and organisational levers an innovating firm can act upon to streamline its journey toward Open Innovation. Theoretical and managerial implications of using these levers for implementing Open Innovation are discussed at length.     

A measure of regional influence with the analytic network process

The metropolitan region is commonly defined by a socio-spatial network of urban nodes that are linked in territory and function. Such a network is differentiated by size and dominance of the linked nodes, characterized by physical or virtual flows of a wide-ranging variety. The analytic network process (ANP) is a multi-criteria analytic method that measures the influence or dominance of the nodes in a network with feedback. We illustrate how ANP determines county rank as a measure of influence in a metropolitan statistical area (MSA) defined by its interrelated socio-economic and spatial elements qualitatively and quantitatively. We compare the ANP results to similar measures of regional influence in the literature.     

Ghettos and enclaves in the cross-place realm: mapping socially bounded spaces across cities

Since the early Chicago School, urban researchers have used residential proximity to assess contacts within and between racial and ethnic groups. This approach is increasingly limited. Diverse groups use email, social networking sites, instant messaging and mobile phones to communicate across urban zones and distant cities. These practices enable mutual support among far-flung family members and co-ethnics as they engage with an array of institutions throughout their day. Through interviews and observations that include women and men of diverse occupations, races and national origins, the author explores how and why cross-place enclosures of sociality and resources develop. Rather than framing the residential area as the locus of racial/ethnic concentration, the author focuses on cross-place concentrations in the technologically mediated workspace. This study enhances theorization of the structural negotiations, interpersonal pressures and group preferences that produce separate lifeworlds in globalizing cities.

Robustness of the air transport network

This paper presents a methodology for the detection of critical airports (those whose isolation would cause the largest losses in network connectivity) in the global air transport network (ATN), based on simulating an attack on selected ATN airports using different adaptive selection criteria. The performances of several node selection criteria are compared, together with a new criterion based on Bonacich power centrality. The results show that most critical airports can be detected with an adaptive strategy based on betweenness centrality. The detection of such airports may help the development of contingency plans to develop an appropriate response to any airport closure.     

The development of critical capabilities in foreign subsidiaries: disentangling the role of the subsidiary’s business network

Within business literature in general, capabilities have advanced to the prime determinant of the corporation’s economic rents. Within international business literature, it is further assumed that multinational corporations can enhance their pool of capabilities through foreign subsidiaries. Foreign subsidiaries are seen as means to assimilate new capabilities from their local, external network and integrate these capabilities into the multinational corporation. Data from more than 2000 foreign subsidiaries shows that some foreign units actually are endowed with superior capabilities which are useful for other corporate entities. It is argued that the development of critical capabilities within these subsidiaries is driven not only by internal corporate actors, but also by external actors. The analysis provides evidence that the role of different internal and external network partners for capability development varies according to the functional activity under consideration. Thus, subsidiaries benefit from various internal and external network actors in very different ways. The contribution ends with some conclusions and some avenues for future research.     

Does social capital determine innovation? To what extent?

This paper deals with two questions: Does social capital determine innovation in manufacturing firms? If it is the case, to what extent? To deal with these questions, we review the literature on innovation in order to see how social capital came to be added to the other forms of capital as an explanatory variable of innovation. In doing so, we have been led to follow the dominating view of the literature on social capital and innovation which claims that social capital cannot be captured through a single indicator, but that it actually takes many different forms that must be accounted for. Therefore, to the traditional explanatory variables of innovation, we have added five forms of structural social capital (business network assets, information network assets, research network assets, participation assets, and relational assets) and one form of cognitive social capital (reciprocal trust). Based on the survey data administered from April to June 2000 to 440 manufacturing firms of diverse industries in a region in the southwest of Montréal, we have found that 68.5% of the firms have developed product or process innovations during the 3 years preceding the survey. Assuming that innovation is not a discrete event but a complex process, we have modeled the decision to innovate as a two-stage decision-making process: in the first stage, the firms deal with the decision about whether to innovate or not whereas, at the second stage, the firms that have decided to innovate must make a decision about the degree of radicalness of the innovation to undertake. In a context where empirical investigations regarding the relations between social capital and innovation are still scanty, this paper makes contributions to the advancement of knowledge in providing new evidence regarding the impact and the extent of social capital on innovation at the two decision-making stages considered in this study. Regarding the decision to innovate or not that firms must initially make, we have provided strong evidence that diverse forms of social capital influence this decision and, more importantly, that marginal increases in social capital, especially in social capital taking the forms of participation assets and relational assets, contribute more than any other explanatory variable to increase the likelihood of innovation of firms. As for the decision to be made at the second stage concerning the magnitude of radicalness to bring in the development of new product or process innovations, this paper contributes to the advancement of knowledge by supplying the strongest evidence that diverse forms of social capital determine the radicalness of innovation, and more importantly, that social capital taking the form of research network assets contributes more than any other explanatory variable to explain the radicalness of innovation. The second variable that exerts the strongest impact on the radicalness of innovation is the number of different advanced technologies employed by firms for production.     

Reoptimization procedures in shortest path problem

In most algorithms for Transportation and Communication Models a sequence of Shortest Path Problems must be solved, where each problem is only slightly different from the preceding. Computational procedures are proposed to find the new shortest paths starting from the old shortest paths in two cases: i) the node from which the shortest paths are to be determined is changed; ii) the cost of one are is modified (either increased or decreased).This research was partially done while the author was visting the Centre de Recherche sur les Transports, Université de Montréal, with a financial support of the National Research Council of Italy.     

Governance and resource interaction in networks. The role of venture capital in a biotech start-up

This paper examines venture capital (VC) governance in innovation processes. The VC literature often presents the relationship between a VC firm and a start-up as dyadic and analyzes it with agency theory. In contrast, this paper deploys the resource interaction framework presented in Håkansson and Waluszewski (2002) to governance and innovation in networks. The paper reports an in-depth case study of Pyrosequencing, a Swedish biotech firm financed with VC. The results from this study reveal how the relationship between a VC and a start-up company is embedded in a wider network and how the governance of the VC spreads in the surrounding network and influences a start-up's possibilities to develop organizational and technical resource interfaces to critical counterparts such as suppliers and customers.
