Co-evolution of the strategic reorientation of port actors: insights from the Port of Rotterdam and the Port of Barcelona

This paper explores changes in the strategic orientation of port authorities and terminal operators towards the hinterland network in the Ports of Rotterdam and Barcelona. Port authorities and terminal operators are economically, institutionally and geographically related organizations. The argument here is that such organizations experience a mutually influential and interactive effect in their strategy over time. The research explores the evolution of the market, institutional and governance forces behind these organizations’ strategic orientation, while acknowledging their interdependence and interrelationship. To that end, it builds a conceptual framework analysing these organizations’ strategies in different points in time. It draws upon firms and port theories to design a co-evolutionary framework, which is later refined with insights gained from an empirical study of the port context.     

Do telecom carrier takeovers create value? Longitudinal analysis of U.S. telecom carrier takeovers from 1996 to 2005

Takeovers by telecommunications carriers have surged during between 1996 and 2005, stimulated by the Telecommunications Act of 1996. In this study, we hypothesize and test the short-term and long-term performance of telecommunications carrier mergers and acquisitions (M&As) between 1996 and 2005 according to three main categories (strategic types, bidder characteristics, and payment methods). For short-term performance, this study investigates abnormal market returns of bidding firms after M&A announcements and our study shows that telecommunications carrier M&A announcements do result in a significant increase in shareholder wealth in the short run. However, from a long-term perspective, which has been investigated in terms of the survival rate and the operating performance after M&As, the telcos experience a statistically significant decrease of up to 10%. The results also show that though strategic type, bidder characteristics, and payment method play an important role in the value creation of M&As in the short term, only the bidder size matters in the success of M&As over a long period of time.     

From Davos,Switzerland to Mombasa,Kenya: a position paper on the adoption of the ‘Davos declaration’ by hotels

Climate change has been identified as a major challenge in the achievement of sustainable development especially for developing countries like Kenya. There has been a wide acknowledgement that there is a need for long-term strategies for the industry players to reduce their contribution to climate change in line with other industries. Industries and societal sectors have sought ways of mitigating the causes of climate change. The Second International Conference on Climate Change and Tourism, held in Davos, Switzerland, on 3 October 2007, provided practical guidelines for the industry in response to climate change. This paper seeks to evaluate the adoption of the ‘Davos Declaration’ among selected Mombasa hotels in terms of water, energy and waste management. Results indicate that despite wide knowledge among hoteliers on the impacts of climate change and the role hotels can play in its mitigation, most hoteliers are slow in adopting the mitigation measures.     

The emergence of home-based accommodations in Iran: A study of self-organization

This paper examines the Iranian home-based accommodation sector using the theory of self-organization. With the aim of identifying the sector's organizing principles, interviews were conducted with the accommodation operators, providing 117 statements which were linked based on their key ideas and/or words. Using UCINET6, a network diagram of five organizing principles were identified: collective identity, balanced legitimacy, local embeddedness, mindful market, and networked finance. While the combination of these organizing principles is interpreted within the Iranian context, broad assumptions can be inferred. It is speculated that a collective aiming to organize itself needs to be considerate of its interactions with members of the collective, the authoritative body, the local community, the market, and capital. Additionally, each separate organizing principle might have relevance for small businesses in various industries. The study contributes to the commercial home and home-based accommodation literature while also providing insights into tourism development in Iran. Furthermore, the method used to identify organizing principles is considered novel and can be used with other collectives.     

Becoming empowered: organization change in a telecom company

The notion of empowerment has been used in the management discourse since at least the 1980s. As a normative model for the distribution of decision-making mandate and administrative and operative responsibilities, empowerment serves as a new shopfloor model or ideology for decentralized organizations of the new workplace. The practice of empowerment is, however, not very often empirically researched, causing a confusion about what empowerment implies in terms of shopfloor activities. This paper presents an extensive organization development programme at a Swedish telecommunication company. Rather than being an easily implemented model, empowerment appears as a complex, heterogeneous process in which the empowering of employees is embedded in local practices and workplace cultures.
