Abstract
Purpose
The purpose of this paper is to apply the concept of blind spot to illustrate the misapplication of extant global strategies to emerging markets. The authors discuss cases of multinationals and indigenous local companies to draw insights on firm operations in emerging markets. The authors unpack four specific blind spots that have resonated repeatedly in their operations: an adherence to unqualified scaling, the intractability of localization, the opacity of non-government intervention, and an undue attention to disruption rather than transformation. The study concludes with recommendations that can help companies be better aware of the blind spots and manage more effectively in emerging markets.

Findings
Four blind spots: an adherence to unqualified scaling, the intransitivity of localization, the illusion of non-government intervention, and an undue attention to disruption rather than transformation.
Practical implications
The paper is primarily for practitioners.
Originality/value
This study presents some of the key findings from our previous studies on emerging market issues. The authors recently published four different books on various themes on emerging markets. The findings presented in this paper come strictly from these previous projects.

Abstract
Purpose
The purpose of this paper is to extract the angle information of direct P wave within multidimensional vibration signals obtained through the sensor array, and to realize high precision shallow burst point localization based on direct of angle (DOA).
Design/methodology/approach
This paper presents a method which combines adaptive covariance matrix (ACM) algorithm with geometric constraint conditions for extracting the angle information of direct P wave by using its polarization characteristics. First, modify the obtained three-dimensional vibration data by using attitude rotation matrix and unify the coordinate system of vibration field. Next, construct the beam model of direct P wave by making use of ACM algorithm and extract its angle information. Finally, modify P wave beam model by taking advantage of the space geometric constraint relations between nodes.
Findings
The results of numerical simulation show that this method not only can extract the angle information of direct P wave arriving at each node effectively, but also can evaluate the quality of extracted angle information of direct P wave. Meanwhile, the results of underground shallow explosion experiment show that this method can extract the angle information of direct P wave of each node significantly and can realize underground shallow explosion source localization based on DOA by using this information, the location error can be limited less than 50 cm and satisfies the location requirements of shallow burst point.
Originality/value
This paper provides a method for various problems of underground localization based on the sensor array, such as directional demolition blasting, underground damage assessment, earth-penetrating projectile burst point positioning in weaponry industry testing plant, etc., and has definite value to engineering application in underground space positioning field.

Abstract
Purpose
The purpose of this paper is to verify the correctness and feasibility of simultaneous localization and mapping (SLAM) algorithm based on red-green-blue depth (RGB-D) camera in high precision navigation and localization of celestial exploration rover.
Design/methodology/approach
First, a positioning algorithm based on depth camera is proposed. Second, the realization method is described from the five aspects of feature detection method, feature point matching, point cloud mapping, motion estimation and high precision optimization. Feature detection: taking the precision, real-time and motion basics as the comprehensive consideration, the ORB (oriented FAST and rotated BRIEF) features extraction method is adopted; feature point matching: solves the similarity measure of the feature descriptor vector and how to remove the mismatch point; point cloud mapping: the two-dimensional information on RGB and the depth information on D corresponding; motion estimation: the iterative closest point algorithm is used to solve point set registration; and high precision optimization: optimized by using the graph optimization method.
Findings
The proposed high-precision SLAM algorithm is very effective for solving high precision navigation and positioning of celestial exploration rover.
Research limitations/implications
In this paper, the simulation validation is based on an open source data set for testing; the physical verification is based on the existing unmanned vehicle platform to simulate the celestial exploration rover.
Practical implications
This paper presents a RGB-D camera-based navigation algorithm, which can be obtained by simulation experiment and physical verification. The real-time and accuracy of the algorithm are well behaved and have strong applicability, which can support the tests and experiments on hardware platform and have a better environmental adaptability.
Originality/value
The proposed SLAM algorithm can deal with the high precision navigation and positioning of celestial exploration rover effectively. Taking into account the current wide application prospect of computer vision, the method in this paper can provide a study foundation for the deep space probe.

Abstract
Purpose
The purpose of this paper is to uncover the underlying drivers of sustained high performing companies based on a field study of 127 companies in Brazilian, Russian, Indian and Chinese (BRIC) and Association of Southeast Asian Nations (ASEAN) emerging markets. Understanding these companies provides a complementary way of appraising the growth, development and transformation of emerging markets. The authors synthesize the findings in an overarching framework that covers six strategies for building and sustaining legacy that leads to the succession of intergenerational wealth over time: overcoming institutional voids, inclusive markets, deepening localization, nurturing government support, building core competencies and harnessing human capital. The authors relate these strategies to different levels of development using Prahalad and Hart’s BOP framework.
Design/methodology/approach
This study examines the underlying drivers of sustained high-performance companies based on field studies from an initial set of 105,260 BRIC companies and close to 500 companies in ASEAN. The methods employed four screening tests to arrive at a selection of the highest-performing firms: 70 firms in the BRIC nations and 58 firms from ASEAN. Following the selection, the authors constructed cases using primary interviews and secondary data, with the assistance of Ernst & Young and with academic colleagues in Manila. These studies were originally conducted in two separate time periods and reported accordingly. This paper synthesizes the findings of these two studies to arrive at an extended integrative framework.
Findings
From the cases, the authors examine six strategies for building and sustaining legacy that lead to high performance over time: overcoming institutional voids, creating inclusive markets, deepening localization, nurturing government support, building core competencies and harnessing human capital. To address the evolving state of institutional voids in these countries, the authors employ similar methods to hypothesize the placement of these strategies in the context of the world economic pyramid, initially formulated as the “bottom of the pyramid” framework.
Originality/value
This paper synthesizes and extends the authors’ previous works by proposing the concept of legacy to describe the emergence and succession of local exemplary firms in emerging markets. This study aims to complement extant measures of nation-growth based primarily on GDP. The paper also extends the literature on institutional voids in shifting the focus from the mix of voids to their evolving state. Altogether, the paper provides a complementary narrative on assessing the market potential of emerging markets by adopting several categories of performance.

Abstract
How do you efficiently design a global yet local user experience for Web sites? Arguably, the user-centered design approach has been one of the best methods in designing a successful user experience for Web services in the initial market, but why isn’t this process applied to international markets? This chapter makes a case for applying a user-centered design process to the international expansion of Web sites and discusses issues impacting the creation of a successful user experience for local audiences. Although this chapter primarily focuses on designing large scale Web services, many of the principles can be applied to any sites that undergo internationalization.

Abstract
Purpose
The study aims to examine the causes of the divergent patterns of contemporary transnational engagement with China among new Chinese immigrants and the effect of transnational entrepreneurship on migrants’ integration into their host societies.
Methodology/approach
It is based on a multi-sited ethnographic study that contains interviews, participant observations, and analysis of relevant event coverage and commentaries by the media, which were conducted between 2008 and 2013 in Singapore, the United States, and China.
Findings
The study finds that different migration histories, structural circumstances in both sending and receiving societies, and locations in the transnational social field give rise to divergent patterns of economic transnationalism, and that the rise of China has opened up new avenues for transnational entrepreneurship, which has not only benefited hometown development in China but also created economic opportunities for Chinese immigrants, leading to desirable mobility outcomes. In particular, transnational entrepreneurship has promoted deeper localization rather than deterritorialization and contributed to strengthening the economic base of the existing ethnic enclave, which in turn offers an effective alternative path for migrants’ integration in their host societies.
Research limitations
The study is exploratory in nature. As with all ethnographic studies, its generalizability is limited.
Social implications
The study suggests that, when transnational entrepreneurship is linked to the existing ethnic social structure in which a particular identity is formed, the effect on the group becomes highly significant. The comparative approach of the study can help unveil different dynamics, processes, and consequences of transnationalism and complex factors behind variations on diasporic development and immigrant integration.
Originality/Value
Looking at entrepreneurship beyond nation-state boundaries and beyond the economic gains of individual migrants.

The purpose of this paper is to propose an enhanced pose tracking method using progressive scan matching, focusing on accuracy, time efficiency and robustness.
Abstract
Purpose
The purpose of this paper is to propose an enhanced pose tracking method using progressive scan matching, focusing on accuracy, time efficiency and robustness.
Design/methodology/approach
The general purpose of localization algorithms is to dynamically track a robot instead of globally locating one. In this paper, progressive scan matching is used to promote the performance of pose tracking. Rotational and translational samples are separately generated to accelerate the calculation and to increase the accuracy. Progressive iteration of sample generation can ensure localization to achieve a specific precision. The direction of localization uncertainty is taken into consideration to increase robustness. Nonlinear optimization is adopted to achieve a more precise result.
Findings
The proposed method was implemented on a self-made mobile robot. Two experiments were conducted to test the accuracy and time efficiency of the method. The comparison with the basic Monte Carlo localization shows the advantages of the method. Another two experiments were conducted to test the robustness of the method. The result shows that the method can relocate a robot from an inaccurate place if the offset is moderate.
Originality/value
An enhanced pose tracking method is proposed to promote the performance by separately processing rotational and translational samples, progressively iterating the sample generation, taking the direction of localization uncertainty into consideration and adopting nonlinear optimization. The proposed method enables a robot to accurately and quickly locate itself in the environment with robustness.

Abstract
Purpose
Augmented reality (AR) has become one of the most promising technologies in construction since it can seamlessly connect the physical construction environment and virtual contents. In view of the recent research efforts, this study attempts to summarize the latest research achievements and inform future development of AR in construction.
Design/methodology/approach
The review was conducted in three steps. First, a keyword search was adopted, and 546 papers were found from Scopus and Web of Science. Second, each paper was screened based on the selection criteria, and a final set of 69 papers was obtained. Third, specific AR applications and the associated technical details were extracted from the 69 papers for further analysis.
Findings
The review shows that: (1) design assessment, process monitoring and maintenance management and operation were the most frequently cited AR applications in the design, construction, and operation stages, respectively; (2) information browser and tangible interaction were more frequently adopted than collaborative interaction and hybrid interaction; and (3) AR has been integrated with BIM, computer vision, and cloud computing for enhanced functions.
Originality/value
The contributions of this study to the body of knowledge are twofold. First, this study extends the understanding of AR applications in the construction setting. Second, this study identifies possible improvements in the design and development of AR systems in order to leverage their benefits to construction.

Abstract
Purpose
This paper aims to model a decision support system (DSS) that could overcome the oversimplified, subjective, compensatory decision logic of extant purchasing portfolio models (PPMs) by leveraging the firms’ procurement-related knowledge base.
Design/methodology/approach
The DSS was developed through a fuzzy-based approach, whose design and application were framed within a case study in a multinational company.
Findings
The application of the fuzzy-based DSS to a product class suggests investing in the relationship with two specific suppliers and to loosen the relationship with a third one.
Research limitations/implications
Exploiting the fuzzy set theory and fostering the elicitation of procurement-related knowledge from the decision-makers, the DSS effectively tackles the concerns about the existing PPMs by including strategic-oriented priorities and contextual constraints in the evaluation.
Practical implications
The recommendations in output from the DSS are feasible, more analytical and easy to interpret, enabling knowledge sharing, group decision processes and better decision-making.
Originality/value
To the best of the authors’ knowledge, this manuscript is the first attempt to effectively integrate traditional PPMs with contextual, strategy-related factors to refine the purchasing directions and make them objective.

Abstract
The chapter discusses the characteristics of audiovisual (AV) media sectors in the Baltic Sea region. Therein it focuses on the specifics of media industries in small countries in the region as they are challenged in ways notably different from large countries with large domestic markets for media content. It discusses the differences between the AV media industries in the Nordic and Baltic countries and suggests that while in the first case long-term welfare society policies and conscious policy-driven system building have conditioned growth and international success then also in the second case innovation policy rationales have facilitated recent growth and dynamics. It then discusses the specific challenges, especially platformisation to small media industries in contemporary globalising media markets, and suggests that opportunities to resist these challenges may be in local inter-sectoral cooperation, that is, in building cross-innovation systems.
