Internationalisation strategies of African MNEs: a case analysis of Angolan and Mozambican enterprises

This study investigates the internationalisation strategies of Lusophone Africa multinational enterprises (LAMNEs) from Angola and Mozambique. While previous scholarship examining the investment decisions and actual investment commitments found that MNEs make choices to internationalise incrementally to reduce uncertainty, this research expands this body of scholarship by identifying Angolan and Mozambican MNEs that were born global or created to become international new ventures (INVs). Key implications of this study suggests that despite several disadvantages faced by entrepreneurs in frontier economies, particularly in Angola and Mozambique LAMNEs relied on external resources to launch themselves into international markets, utilising web-enabled digital and virtual resources, such as the Internet, social media and online professional communities of practice. In addition, most did not enter foreign markets alone and chose to rely on modes of entry that included joint ventures and partnerships, mergers and acquisitions (M&A), e-commerce, and e-business.https://doi.org/10.1504/IJEXPORTM.2019.101809Accepted manuscriptPublished versio

Internationalization strategies of frontier Lusophone-African multinational enterprises: comparative case studies of Angola and Mozambique

Internationalization theories suggest that enterprises from emerging and frontier markets will adopt different entry modes than those in advanced economies. There are very few studies to date, however, examining the process of how multi-national enterprises (MNEs) from frontier markets internationalize or evaluating which factors influence their mode of entry into global markets. This research investigates the internationalization strategies of Lusophone Africa MNEs from Angola and Mozambique, more specifically their entry mode, to expand the framework for entry mode strategies to include the motivations and issues of MNEs from emerging and frontier economies. Surveys, as well as in-depth, in-country, qualitative interviews reveal that these frontier and emerging market MNEs opted for equity-based investment strategies as their preferred mode of entry. A significant group second group opted for e-commerce/e-business strategies, and direct and indirect exports. Finally, a smaller portion of the interviewees chose Greenfield investment as a mode of entry. Many of these MNEs could be classified as born global/INV.https://doi.org/10.1080/15475778.2017.1335127Accepted manuscriptPublished versio

Social media as a data gathering tool for international business qualitative research: opportunities and challenges

Lusophone African (LA) multinational enterprises (MNEs) are becoming a significant pan-African and global economic force regarding their international presence and influence. However, given the extreme poverty and lack of development in their home markets, many LA enterprises seeking to internationalize lack resources and legitimacy in international markets. Compared to higher income emerging markets, Lusophone enterprises in Africa face more significant challenges in their internationalization efforts. Concomitantly, conducting significant international business (IB) research in these markets to understand these MNEs internationalization strategies can be a very daunting task. The fast-growing rise of social media on the Internet, however, provides an opportunity for IB researchers to examine new phenomena in these markets in innovative ways. Unfortunately, for various reasons, qualitative researchers in IB have not fully embraced this opportunity. This article studies the use of social media in qualitative research in the field of IB. It offers an illustrative case based on qualitative research on internationalization modes of LAMNEs conducted by the authors in Angola and Mozambique using social media to identify and qualify the population sample, as well as interact with subjects and collect data. It discusses some of the challenges of using social media in those regions of Africa and suggests how scholars can design their studies to capitalize on social media and corresponding data as a tool for qualitative research. This article underscores the potential opportunities and challenges inherent in the use of social media in IB-oriented qualitative research, providing recommendations on how qualitative IB researchers can design their studies to capitalize on data generated by social media.https://doi.org/10.1080/15475778.2019.1634406https://doi.org/10.1080/15475778.2019.1634406https://doi.org/10.1080/15475778.2019.1634406https://doi.org/10.1080/15475778.2019.1634406Accepted manuscriptPublished versio

Lusophone-African SME internationalization: a case for born global and international joint ventures

This study investigates the internationalization strategies of Lusophone Africa multinational enterprises (MNEs) from Angola and Mozambique, more specifically their entry mode. Information was gathered through a survey of 29 MNEs upper management respondents and subsequent face-to-face semi-structured interviews with 24 of them in their countries. The results suggest that most MNEs opted for equity-based investment strategies, mainly joint venture and mergers and acquisitions (M&A) as their preferred mode of entry when internationalizing. A significant group of them opted for e-commerce/e-business strategies and direct and indirect exports. A smaller portion of the interviewees chose Greenfield investment as a mode of entry. Many of these MNEs could be classified as born global/international new venture (INV). Finally, this study presents a conceptual framework for use in studying the entry mode choice of enterprises from Lusophone Africa frontier markets and presents research propositions for better understanding the determinants of entry mode strategies of enterprise from Angola and Mozambique.https://doi.org/10.1080/15475778.2019.1634406Accepted manuscriptPublished versio

Why do demand responsive transport systems fail?

In developed countries, Demand Responsive Transport (DRT) (loosely termed 'paratransit' in US parlance) emerged in the 1970s to serve the specialist niche market of people with mobility difficulties. DRT systems are starting become a mainstream public transport mode and this paper examines mainstream public transport DRT schemes from around the world that have failed, in order to identify the reasons for failure, and draw lessons to help prevent similar outcomes occurring. Research for the Intermode study developed detailed cases of 72 DRT projects. A number of key failed cases are reported together with a note of the lessons that each provides. This is followed by a generic analysis of failure factors based on a marketing approach. It is concluded that DRT projects are often not realistically costed or designed with a full understanding of the market they are to serve. There is a very dangerous temptation to offer too flexible a service and to include costly technological systems, when they may not be needed. An incremental approach, if possible, appears sensible. DRT also requires more marketing effort and skills than is traditional in conventional bus operations, but above all, it requires new skills in working in partnership. It is concluded that the latter area is where the root of DRT failure is often to be found

Subtleties of witnessing quantum coherence in non-isolated systems

Identifying non-classicality unambiguously and inexpensively is a long-standing open challenge in physics. The No-Signalling-In-Time protocol was developed as an experimental test for macroscopic realism, and serves as a witness of quantum coherence in isolated quantum systems by comparing the quantum state to its completely dephased counterpart. We show that it provides a lower bound on a certain resource-theoretic coherence monotone. We go on to generalise the protocol to the case where the system of interest is coupled to an environment. Depending on the manner of the generalisation, the resulting witness either reports on system coherence alone, or on a disjunction of system coherence with either (i) the existence of non-classical system-environment correlations or (ii) non-negligible dynamics in the environment. These are distinct failure modes of the Born approximation in non-isolated systems.Comment: 16pp, 2 figs, 5 thms. v2: typos corrected, references added and small change to title to reflect that of published versio

Measuring eccentricity in binary black hole inspirals with gravitational waves

When binary black holes form in the field, it is expected that their orbits typically circularize before coalescence. In galactic nuclei and globular clusters, binary black holes can form dynamically. Recent results suggest that $\approx5\%$ of mergers in globular clusters result from three-body interactions. These three-body interactions are expected to induce significant orbital eccentricity $\gtrsim 0.1$ when they enter the Advanced LIGO band at a gravitational-wave frequency of 10 Hz. Measurements of binary black hole eccentricity therefore provide a means for determining whether or not dynamic formation is the primary channel for producing binary black hole mergers. We present a framework for performing Bayesian parameter estimation on gravitational-wave observations of black hole inspirals. Using this framework, and employing the non-spinning, inspiral-only EccentricFD waveform approximant, we determine the minimum detectable eccentricity for an event with masses and distance similar to GW150914. At design sensitivity, we find that the current generation of advanced observatories will be sensitive to orbital eccentricities of $\gtrsim0.05$ at a gravitational-wave frequency of 10 Hz, demonstrating that existing detectors can use eccentricity to distinguish between circular field binaries and globular cluster triples. We compare this result to eccentricity distributions predicted to result from three black hole binary formation channels, showing that measurements of eccentricity could be used to infer the population properties of binary black holes.Comment: 12 pages, 7 figures, 2 table

Reactivity Study of Platinum Nanoparticles and Nanowires Inside the Channels of Mesoporous Silica

Pt metal nanowires and nanoparticles were prepared using mesoporous silica as the template. Mesoporous silica with straight 1-dimensional, tortuous 1-dimensional and 3-dimensional channels was used. The experimental techniques included CO oxidation, Chemisorption, XRD, and STEM. CO oxidation and chemisorption provided the data to calculate the intrinsic reactivity, known as turn over frequency (TOF). Powder XRD was used to measure line broadening. The FWHM of the XRD line broadening was used with the Scherrer formula to determine Pt metal crystallite size. STEM images permitted for the measurement of the particle diameters, and the determination of morphology. Two commercially available reference samples were used to provide a benchmark for comparison, namely Pt on alumina and Pt on silica. The resulting TOF of these reference catalysts were identical, confirming that the CO oxidation reaction is structure insensitive
