Successful and unsuccessful radical transformation of multinational mobile telephony companies: the role of institutional context

A number of prominent European multinational mobile telephony companies (MNMTCs) have their origins in state-owned monopolies that successfully undertook radical transformation in the late 1980s to late 1990s. Not only did they face liberalization of their domestic markets but they also moved from fixed-line telephony to mobile telephony prior to rapid expanded overseas. Our study focuses on Telenor whose operations currently span the Nordic region and Southeast Asia. Like other MNMTCs, Telenor currently faces another period of radical change as global digital services providers are set to ride on the connectivity MNMTCs supply thereby reducing them to “dumb-pipes”. Our study indicates that Telenor has abandoned radical transformation for “modernization” of its extant operations. For an understanding of why this second radical change is proving arduous for MNMTCs, we argue that there is a need to take into consideration institutional change

Functional-level transformation in multi-domestic MNCs: transforming local purchasing into globally integrated purchasing integrated purchasing

This paper revisits Bartlett and Ghoshal’s transnational theory of the MNC in relation to multi-domestic MNCs. We argue that the aggregate level of analysis adopted by Bartlett and Ghoshal is unhelpful for identifying significant changes in multi-domestic MNCs at the level of discrete functions. We argue that a more disaggregated level of analysis is required. Our analysis of two cases of multi-domestic MNCs that have undertaken the global integration of their locally distributed purchasing functions indicates that while significant change to the purchasing function has occurred, at the aggregate level both MNCs remain multi-domestic. In both cases the decision to integrate local purchasing was regarded as having more obvious benefits than integrating other functions such as marketing. While both of our case multi-domestic MNCs may in future choose to integrate other functions and develop into full-fledged transnational companies we argue that there is no inevitability to this. Indeed global integration may cease with the purchasing function. A second theme in this paper is that we argue that Bartlett and Ghoshal’s transnational theory has a biased view of what constitutes effective governance mechanisms for achieving global integration, local responsiveness and worldwide learning and that it would greatly benefit from a more balanced application of hierarchical and relational governance mechanisms

The digital challenge for multinational mobile network operators. More marginalization or rejuvenation?

Multinational mobile network operators (MNOs) rapidly emerged in the early 1990s and for a decade and a half were the dominant actors in their industry. We analyze the development and competitiveness of a typical MNO, Telenor. With the introduction of 4G in 2010, we show that Telenor, like other MNOs largely failed to respond to the opportunity that connectivity provided to develop digital services. Instead, these were developed by technology platform companies such as Amazon, Google and Microsoft. Telenor became a marginalized supplier of standardized internet connectivity. We argue that the ‘decade of lost opportunity’ (2010-2020) for Telenor was a product of a lack of ‘recombinant firm-specific advantages’ (FSARs). With the launch of 5G, an emerging global digital infrastructure, this sidelining is set to intensify unless Telenor responds to this new opportunity by developing B2B digital services. We analyze the FSARs that are necessary for a successful transition of capturing the value that 5G provides and the degree to which they are present, or potentially present, in Telenor

VUCA and the future of the global mobile telco industry

The disruption global digitally based firms are imposing on the positions of established multinational telcos is not just in degree, but also in kind. As such, the telcos are entering a period of VUCA. Although digitally based competitors could suffer from liabilities of ‘outsidership’, employing the telco Telenor as a case, we argue that the physical presence of telcos in local markets will be insufficient to avoid a future as utilities or dumb-pipes. One significant issue as they confront VUCA is therefore whether telcos are able to develop and apply dynamic capabilities

The effect of organizational separation on individuals' knowledge sharing in MNCs

The ability of an organization to apply knowledge globally has been conceptualized as critical for the existence of multinational corporations (MNCs). We argue for an organizational separation effect on knowledge sharing that challenges the view of the MNC as a latent social community. Using a unique data-set of more than 4.000 individual responses from an MNC, Telenor, we test how three types of drivers for individuals’ knowledge sharing –individuals’ motivation, and individuals’ perceptions of organizational values and organizational work practices- work differently within, as opposed to across, business units. Our analysis suggests that while intrinsic motivation, innovative values and job autonomy are relatively important drivers of knowledge sharing within the business units, extrinsic motivation, result-oriented values and participation in corporate employee development are relatively more important for knowledge sharing across business units

Contextualizing AMO explanations of knowledge sharing in MNEs: the role of organizational and national culture

Ability, motivation, and opportunity (AMO) approaches have dominated studies of knowledge sharing in multinational enterprises (MNEs). We argue that there is a need to consider both the national and organizational cultural contexts. Beyond their direct influence on knowledge sharing with colleagues in other business units (BUs), national and organizational culture significantly reinforce the positive relation between individual motivation and knowledge sharing. Thus, our multi-level approach to knowledge sharing in MNEs gives rise to a contextualized AMO approach that provides a novel and more potent understanding of variations in knowledge sharing. At the individual level, our approach includes the degree of ability in the sense of professional competence, intrinsic motivation, and opportunities to interact with colleagues in other BUs. At the organizational and country levels, we examine the direct and indirect effects of a collaborative culture on knowledge sharing. We employ data from an MNE that operates across a variety of regions, including the Nordic countries, Central and Eastern Europe, and Southeast Asia. The sample consists of 11,484 individuals nested in 1,235 departments in 11 countries. As well as confirming the significance of individual competence, intrinsic motivation, and opportunities for interaction for knowledge sharing, our findings reveal that both organizational culture and national culture are important factors for our understanding of knowledge sharing. This suggests that over and above recruiting intrinsically motivated employees, managers can enhance knowledge sharing by developing collaborative organizational cultures at the departmental level

Attachment of Rod-Like (BAR) Proteins and Membrane Shape

Previous studies have shown that cellular function depends on rod-like membrane proteins, among them Bin/Amphiphysin/Rvs (BAR) proteins may curve the membrane leading to physiologically important membrane invaginations and membrane protrusions. The membrane shaping induced by BAR proteins has a major role in various biological processes such as cell motility and cell growth. Different models of binding of BAR domains to the lipid bilayer are described. The binding includes hydrophobic insertion loops and electrostatic interactions between basic amino acids at the concave region of the BAR domain and negatively charged lipids. To shed light on the elusive binding dynamics, a novel experiment is proposed to expand the technique of single-molecule AFM for the traction of binding energy of a single BAR domain

Physicochemical and Antibacterial Characterisation of a Novel Fluorapatite Coating

Peri-implantitis remains the major impediment to the long-term use of dental implants. With increasing concern over growing antibiotic resistance there is considerable interest in the preparation of antimicrobial dental implant coatings that also induce osseointegration. One such potential coating material is fluorapatite (FA). The aim of this study was to relate the antibacterial effectiveness of FA coatings against pathogens implicated in peri-implantitis to the physicochemical properties of the coating. Ordered and disordered FA coatings were produced on the under and upper surface of stainless steel (SS) discs respectively, using a hydrothermal method. Surface charge, surface roughness, wettability and fluoride release were measured for each coating. Surface chemistry was assessed by X-ray photoelectron spectroscopy and FA crystallinity by X-ray diffraction. Antibacterial activity against periodontopathogens was assessed in vitro using viable counts, confocal and scanning electron (SEM) microscopies. SEM showed that the hydrothermal method produced FA coatings predominately aligned perpendicular to the SS substrate or disordered FA coatings consisting of randomly aligned rod-like crystals. Both FA coatings significantly reduced the growth of all the examined bacterial strains in comparison to the control. The FA coatings, and especially the disordered ones, presented significantly lower charge, higher roughness and area when compared to the control, enhancing bacteria–material interactions and therefore bacterial deactivation by fluoride ions. The ordered FA layer reduced not only bacterial viability but adhesion too. Ordered FA crystals produced as a potential novel implant coating showed significant antibacterial activity against bacteria implicated in peri-implantitis which could be explained by a detailed understanding of their physicochemical properties

Nanomechanical investigation of soft biological cell adhesion using atomic force microscopy

Mechanical coupling between living cells is a complex process that is important for a variety of biological processes. In this study the effects of specific biochemical treatment on cell-to-cell adhesion and single cell mechanics were systematically investigated using atomic force microscopy (AFM) single cell force spectroscopy. Functionalised AFM tipless cantilevers were used for attaching single suspended cells that were brought in contact with substrate cells. Cell-to-cell adhesion parameters, such as maximum unbinding force (F max) and work or energy of detachment (W D), were extracted from the retraction force–displacement (F–d) curves. AFM indentation experiments were performed by indenting single cells with a spherical microbead attached to the cantilever. Hertzian contact model was applied to determine the elastic modulus (E) of single cells. Following treatment of the cells with neutralising antibody for epithelial (E)-cadherin, F max was increased by 25%, whereas W D decreased by 11% in response to a 43% increase in E. The results suggest that although the adhesion force between cells was increased after treatment, the energy of adhesion was decreased due to the reduced displacement separation as manifested by the loss of elastic deformation. Conclusively, changes in single cell mechanics are important underlying factors contributing to cell-to-cell adhesion and hence cytomechanical characterization is critical for cell adhesion measurements
