Abstract
Purpose
This paper aims to describe an effort to provide for a robust and secure software development paradigm intended to support DevSecOps in a naval aviation enterprise (NAE) software support activity (SSA), with said paradigm supporting strong traceability and provability concerning the SSA’s output product, known as an operational flight program (OFP). Through a secure development environment (SDE), each critical software development function performed on said OFP during its development has a corresponding record represented on a blockchain.
Design/methodology/approach
An SDE is implemented as a virtual machine or container incorporating software development tools that are modified to support blockchain transactions. Each critical software development function, e.g. editing, compiling, linking, generates a blockchain transaction message with associated information embedded in the output of a said function that, together, can be used to prove integrity and support traceability. An attestation process is used to provide proof that the toolchain containing SDE is not subject to unauthorized modification at the time said critical function is performed.
Findings
Blockchain methods are shown to be a viable approach for supporting exhaustive traceability and strong provability of development system integrity for mission-critical software produced by an NAE SSA for NAE embedded systems software.
Practical implications
A blockchain-based authentication approach that could be implemented at the OFP point-of-load would provide for fine-grain authentication of all OFP software components, with each component or module having its own proof-of-integrity (including the integrity of the used development tools) over its entire development history.
Originality/value
Many SSAs have established control procedures for development such as check-out/check-in. This does not prove the SSA output software is secure. For one thing, a build system does not necessarily enforce procedures in a way that is determinable from the output. Furthermore, the SSA toolchain itself could be attacked. The approach described in this paper enforces security policy and embeds information into the output of every development function that can be cross-referenced to blockchain transaction records for provability and traceability that only trusted tools, free from unauthorized modifications, are used in software development. A key original concept of this approach is that it treats assigned developer time as a transferable digital currency.

Abstract
Purpose
The purpose of this paper is to add to the small but growing body of research examining the influence of founder gender on new venture access to venture development programs.
Design/methodology/approach
Hypotheses were tested utilizing a sample of 482 nascent technology ventures which applied for admittance into a venture development organization headquartered in the southern region of the United States from March 2004 through February 2016.
Findings
Findings suggest that female-founded applicant ventures experience a higher likelihood of acceptance into venture development programs than male-founded applicant ventures. Results further suggest that social attention to gender equality reduces this effect for female-founded applicant ventures. Findings extend the understanding of the gendered nature of high-technology venturing and venture development organizations.
Research limitations/implications
The findings of this study may not generalize to new ventures operating in other contexts (e.g., non-U.S., low-tech, and other venture development programs). Additionally, this study's design and data limitations do not allow for the establishment of causality or address founder motivations to apply for acceptance into venture development programs.
Originality/value
This study adds to empirical findings regarding the influence of founder gender on new venture acceptance into venture development programs by developing and testing competing hypotheses. This study also extends extant research by examining the moderating effect of social attention to gender equality on the hypothesized relationships between founder gender and acceptance into venture development programs.

Abstract
Purpose
By combining geopolitical and economic factors and from a geoeconomic perspective, the importance of Gwadar to China and Pakistan is discussed in detail. By applying geoeconomic approach and based on the historical approach, geographical and geopolitical conditions and international development trends of Gwadar port, the authors develop the analytical framework to analyze the Gwadar port and studied its importance in the development of China and Pakistan, as well as the positive influence on the economic growth of both countries.
Design/methodology/approach
A geoeconomic study is done to run a more profound and more comprehensive analysis of China–Pakistan economic relationship, as geoeconomic includes interrelations of geographical, geopolitical and economic factors in international relations.
Findings
The results show that Gwadar Port's development could enhance the economic security of both China and Pakistan. With the opening of Gwadar Port, oil and energy in the Middle East will be imported directly to China through Pakistan's oil pipeline. This is not only oil but also goods from Central Asia, and even Europe and the USA will land from Gwadar Port and enter China through the China–Pakistan Economic Corridor (CPEC). The development of Gwadar port under the CPEC program could also dramatically increase the capacity of Pakistan's maritime trade while reducing its dependence on the current largest port, Karachi, near the India border.
Originality/value
Geo-economics theory is used to run a more profound and more comprehensive analysis of China–Pakistan economic relationship as geoeconomic includes interrelations of geographical, location, geopolitical and economic factors in international relations. By combining geopolitical and economic factors and from a geoeconomic perspective, this study seeks to analyze the Gwadar port development and its implications for both China and Pakistan.

Abstract
Those who would establish high-growth businesses (HGBs) in rural settings face significant challenges. We report findings from more than 80 in-depth interviews regarding the obstacles that rural HGBs face and identify approaches for overcoming these obstacles. First, interviews confirm the need for improved access to a full range of financing options to support HGBs across different development stages. Second, HGBs need in-depth, sophisticated technical assistance, which is generally unavailable in rural areas. Finally, cooperation among financial and technical service providers is vital to program success. Based on these findings, a model is proposed for successful development of HGBs in rural areas.

Abstract
Purpose
Each year, the US defense industry outsources nearly $400 bn of domestic goods and services through competitive bids. These procurement activities are quite often complex and specialized in nature because of a highly regulated federal acquisition contracting environment. Ongoing calls to improve supplier management and drive innovation in the defense industry offers an opportunity to adopt Early Supplier Integration (ESI) initiatives that have proven successful in the private sector. This paper identifies critical ESI activities and acquisition practices that the defense industry should adopt to ensure enhanced effectiveness in new product development.
Design/methodology/approach
Leveraging a conceptual ESI model derived from the research, an in-depth case study of 12 product development projects from a major defense contractor was performed. In the context of project performance, critical ESI activities and moderating effects were assessed.
Findings
Three key ESI activities have the greatest impact on aggregate project performance: system design involvement, design adjustment opportunities and design for manufacturability/assembly/testability involvement. Use of formal supplier agreements also significantly impacts project performance during the development phase. In addition, project complexity and product team maturity were identified as environment moderators; higher complexity projects tended to negatively moderate the impact of ESI upon performance, and higher team maturity levels tended to positively moderate the impact of ESI upon performance.
Originality/value
The results provide a sound framework for empirical validation through future quantitative studies and defense industry analyses. In addition, insights and recommendations for interpretation and adaptation of federal acquisition regulations to allow increased utilization of ESI within the defense industry are substantiated.

Abstract
Regional policy instruments are typically driven by economic rationales, from either a firm or industrial perspective. Yet too often, these rationales are taken as ex ante to the contexts within which firms and industries compete. Recent regional development research has urged a better link be developed between the individual, the firm, and their context, so as to understand the role of regions in supporting effective competitiveness of organizations. In this article, recent research themes are explored that may shed light on the nature of this relationship and that can be developed into an investigative methodology that could aid policy practitioners in generating policy instruments that reflect differing societal constructions of SME reality.
