Abstract
Purpose
The purpose of this paper is to design a very low‐noise transimpedance amplifier (TIA) for a novel multi‐pixel CMOS photon detector which performs secondary electron (SE) detection in the scanning electron microscope (SEM).
Design/methodology/approach
The TIA, which is implemented with three‐stage push‐pull inverters, is optimised using a nomograph technique developed in MATLAB. SPICE simulations are conducted to verify the results generated from MATLAB. Important performance figures are obtained experimentally and these measurements are compared with simulation results.
Findings
A low‐noise TIA fabricated in a standard 0.35 μm CMOS technology was tested. Experimental results obtained show that the TIA connected to a photodiode with a junction capacitance of 0.8 pF can carry out its task effectively with a transimpedance gain of 126.9 dBΩ, a bandwidth of 9.8 MHz, an input‐referred noise of 2.50×10−13 A/√Hz and an SNR of 12.8. The power consumption of the TIA was 49.3 mW. These encouraging results have exhibited the potential of the circuit for use in the CMOS photon detector.
Originality/value
This paper presents a low‐noise transimpedance amplifier that is highly suitable to be used as a critical constituent block for the CMOS photon detector which aims to take over the role of photomultiplier tube in SE detection in the SEM. Solid‐state approaches have recently been reinvigorated for improving certain aspects of SE detection in scanning electron microscopy and this work has supported and contributed to the trend.

Abstract
We examine how a firm’s market-oriented capabilities (in areas such as R&D or marketing) and consumer focus (business-to-business or business-to-consumer) foster its effectiveness in pursuing corporate political activities. We then explore the sustainability of any advantage that firms may gain from their political activities. We develop a conceptual framework to propose that a firm’s political capabilities to implement different political tactics, such as information provision and constituency building, are a product of how related these tactics are to different market-oriented capabilities and to the skills needed to serve different types of customers. Finally, we propose that the integration of market strategies and political strategies provides new insight into the sustainability of the advantages that a firm might gain through political activities.

Abstract
This paper provides a perspective on the field of nonmarket strategy. It does not attempt to survey the literature but instead focuses on the substantive content of research in the field. The paper discusses the origins of the field and the roles of nonmarket strategy. The political economy framework is used and contrasted with the current form of the resource-based theory. The paper argues that research should focus on the firm level and argues that the strategy of self-regulation can be useful in reducing the likelihood of challenges from private and public politics. The political economy perspective is illustrated using three examples: (1) public politics: Uber, (2) private politics: Rainforest Action Network and Citigroup, and (3) integrated strategy and private and public politics: The Fast Food Campaign. The paper concludes with a discussion of research issues in theory, empirics, and normative assessment.

Abstract
Purpose
The COVID-19 pandemic was an eye-opening experience that put to the test our crisis management competencies across many institutions, including those offered by institutions of higher education. This study aims to review the literature on international business (IB) risks and IB education (IBE) to question whether business graduates are equipped to make decisions in today’s volatile, uncertain, complex and ambiguous (VUCA) marketplace.
Design/methodology/approach
While the IB literature has discussed the importance of various sources of risks on global business operations, IBE did not effectively adopt an integrative approach to building the needed risk management competencies related to those risks into our education. The authors argue that this integrative approach to teaching IB is critically needed to prepare future global managers for addressing crises, like that of the pandemic and others. Specifically, this study proposes that this integrated risk management competency can be developed through the building of “synergistic mindsets”.
Findings
This study presents a conceptual framework for the components of the synergistic mindset, with intelligence that directly links to present IB risks. These components are cultural intelligence (CQ), emotional intelligence (EQ), public policy intelligence (PPQ), digital intelligence (DQ) and orchestration intelligence (OQ).
Originality/value
Insights related to IBE effectiveness in addressing today’s VUCA market demands and IB risks are discussed.

Abstract
We show that, in the US telecommunications industry, market participants have a sophisticated understanding of the political process, and behave strategically in their allocation of contributions to state legislators as if seeking to purchase influence over regulatory policy. We find that interests respond defensively to contributions from rivals, take into account the configuration of support available to them in both the legislature and the regulatory commission, and vary their contributions according to variations in relative costs for influence by different legislatures. This strategic behavior supports a theory that commercially motivated interests contribute campaign resources in order to mobilize legislators to influence the decisions of regulatory agencies. We also report evidence that restrictions on campaign finance do not affect all interests equally. The paper therefore provides positive evidence on the nature and effects of campaign contributions in regulated industries where interest group competition may be sharp.

Abstract
Purpose
The purpose of this paper is to critically review and explore how organizations knowledgeably respond to unfavorable institutional environments that exert institutional pressures and thereby limit their decision-making and eventually their actual behavior.
Design/methodology/approach
Based on a thorough structuration and analysis of the literature in management and related fields, the authors present a comprehensive synthesis of organizational knowledgeable responses to institutional pressures.
Findings
Based on the review, the authors categorize organizational knowledgeable responses into three major types – passively responding to avoid non-conformity, reactively mitigating institutional pressures and proactively developing institutional environments toward less interfering setups.
Research limitations/implications
The authors discuss the enabling conditions for the categorized organizational knowledgeable responses as well as limitations to their application. They identify research gaps and formulate research questions to offer promising avenues for future work. The authors expect this detailed synthesis to lay the framework for investigating how the knowledge-based view of the organization influences its knowledgeable response to institutional pressure.
Practical implications
The authors elaborate on distinct passive, reactive and proactive strategies, which firms can apply to cope with institutional pressures. The contribution of this study will be of relevance to practitioners managing organizations in the face of unfavorable institutional setups, as well as to policymakers engaged in the development of institutions and interacting with affected organizations.
Originality/value
This study provides a valuable overview on developments in institutional theory, particularly on contributions to the “nascent literature” that examines heterogeneous organizational knowledgeable responses to institutional pressures.

Abstract
Social movement organizations increasingly engage directly with companies, rather than using the political process to regulate them. This development has spawned lively new literatures on non-market strategy and on social movements, but the two would benefit from engaging each other more effectively. A common framework and set of shared constructs would allow for collaborative theorizing on how new issues emerge into the public sphere, how interest groups mobilize, and how public opinion is formed; transaction cost analysis, with its primarily verbal theorizing, may prove a helpful starting point. Empirical knowledge is growing rapidly, yet many exciting questions remain open.

Abstract
The field of nonmarket strategy has expanded rapidly over the past 20 years to provide theoretical and practical guidance for managers seeking to influence policymaking. Much of this scholarship has built directly on spatial and “pivotal politics” models of lawmaking. While extremely helpful at identifying crucial targets for lobbying, these models treat all policymakers as identical in their abilities to advance legislative agenda items through various policymaking hurdles. We build upon these earlier models, but include policymakers who vary in their relative effectiveness at advancing measures through the legislative process. We identify how the implications of our model deviate from those of conventional (pivotal politics) analyses. We then present an empirical strategy for identifying effective Lawmakers in the United States Congress, and illustrate the utility of this approach for managers developing nonmarket strategies in legislative institutions, relying on the case of banking and financial services reforms between 2008 and 2011.

Abstract
Purpose
This paper aims to investigate the multi-faceted impact of host country risks on the success of private participation in infrastructure projects. The authors make a distinction between exogenous and endogenous risks, differentiating those that are completely beyond the control of the firm from those in which firms might exert some degree of influence to reduce the negative repercussions.
Design/methodology/approach
Drawing on logistic regression analyses, the authors analyze a sample of 10,350 private participation in infrastructure projects in 126 countries from 1997 to 2014.
Findings
The authors find that higher levels of exogenous risk are associated with a lower probability of project success, whereas they find no significant effect for endogenous risk.
Originality/value
By pointing to this differential effect, this study makes a contribution to the current debate in the literature on private participation projects.

Abstract
Purpose
The purpose of this paper is to deal with the issue of market redefinition through an examination of a unique industry that has met with multiple obstacles: online gambling. The main research question is how markets get redefined when quantum technological change occurs, despite the lack of formal support and a highly fragmented industry structure, typical in online industries.
Design/methodology/approach
This industry lends itself to the analysis because of the intense competition for reconstruction of the field among state powers, professional associations, and global forces. The paper provides an archival and qualitative overview of the industry and identify the various forces competing for dominance in the market. It examines the competing logics in this industry and identify the sources and implications of such competition for emerging markets.
Findings
Both broad and specific contributions of this paper are discussed, namely the important role of professional and interest associations in industries without clear geographical boundaries, as well as the growing role for global moderating agencies.
Research limitations/implications
The paper provides a timely example of the ways in which firms organize in the modern business environment. In addition, it discusses the volatile and complex power structure in a global economy. While the research is necessarily processual and does not provide for multiple settings, the extent of legal implications here can be generalized to much smaller differences in global markets.
Originality/value
This paper provides support for the idea that, contrary to many concepts of industry acceptance and growth, legitimacy is not a requisite condition for an industry to prosper.
