    Infrastructure and internet inclusiveness as determinants of e-commerce expansion
    (Association for Industry, Engineering and Management Systems (AIEMS), 2023-12) Augustine, Fred K., Jr.; Rasp, John
    Due to the rapidly increasing number of people around the world with Internet access, the web's global reach is affecting the growth and development of the world economy. At the macro or national level, research has been conducted to examine the growth of E-Business in Developing nations and cultural determinants of e-commerce adoption at a national level and in relation to the digital divide. In a previous study the authors focused on four particular drivers of this expansion: (1) the rapid expansion of availability of the Internet to an ever-growing number of people, (2) the increased affordability of Internet access, as technology and connection costs have plummeted, (3) the everwidening relevance of Internet resources (function, local language access, etc.) to broad swaths of the world's population, and (4) the readiness of a nation (infrastructure, cultural acceptance) to adopt E-Commerce. Results of this study showed that, among other things, the relative importance of the "Price" and "Competitive Environment" sub-components suggest that e-commerce thrives best under a regime of inexpensive Internet connectivity available from a variety of competing suppliers. The current study expands on this analysis by examining the fifty-seven directly measurable dependent variables which constitute the 3i Index to assess which variables are the most significant as determinants of e-commerce expansion.

    Evaluation of a hybrid cold spray and machining method for fabrication of parts with high surface integrity
    (Association for Industry, Engineering and Management Systems (AIEMS), 2023-12) Lee, Xuan Yi; Moscoso-Kingsley, Wilfredo
    Cold spray technology has been proven to have various engineering and manufacturing applications, including the capability to restore previously unrepairable parts. However, like most additively manufactured parts, it will likely require post-processing, such as machining, to improve surface finish and dimensional accuracy. In addition, cold spray deposits are typically porous. The porosity may be detrimental to the mechanical performance of the component. This paper presents a systematic evaluation of cold spray using readily available nitrogen as carrier gas, subsequent machining utilizing negative rake angle tools, and the effect of this novel hybrid fabrication method on subsurface porosity. The machining is optimized via finite element analysis (FEA) and the optimum is verified by experiments. The analysis informs the engineering of the proposed hybrid cold spray/machining method.

    A framework to define and quantify leadership styles within Navy engineering units
    (Association for Industry, Engineering and Management Systems (AIEMS), 2023-12) Praschak, Megan
    The purpose of this study was to develop a framework for the U.S. Navy's leadership styles by assessing self-perceived leadership styles in a sample of reserve Engineering Duty Officers (EDOs) and the Senior Enlisted Leaders (SELs) in these technical units. Transformational and transactional leadership styles were examined using the Multifactor Leadership Questionnaire (MLQ) Form (Avolio & Bass, 2004), while the servant leadership style was examined using the Servant Leadership Self-Assessment Questionnaire (SLSQ) (Sandling, 2021). The effect of rank and the triad leadership position had on leadership style was explored in this study. The survey was made available to all EDOs and SELs (n = 525). A total of 84 surveys were completed (a 16% return rate). Results showed that there was a statistically significant difference in servant leadership between SELs and junior officers. When broken down into the factors of servant leadership this difference was seen in the conceptual skills and putting followers first factors. No statistical differences were seen across leadership triad positions, or between any other ranks for any other leadership style. The findings are discussed for their implications for leadership development in the U.S. Navy.

    How to conduct a case study: A guide for novice researchers
    (Association for Industry, Engineering and Management Systems (AIEMS), 2023-12) Hussein, Abdelnasser
    Case study research has been gaining popularity due to its valuable capacity to provide rich, context-specific data as well as understanding of difficult circumstances. This is demonstrated by the fact that it has been utilized more frequently in recent research that has been published. This popularity may be attributed to the fact that case study research is able to deliver rich information about the case of study. This article presents a brief overview of the literature review that was conducted on the qualitative case-study methodology. It might serve as a quick reference tool for novice researchers who are intrigued about pursuing case studies. In this article, a brief historical overview of the evolution of the case study as a significant qualitative approach is demonstrated in connection to the pioneers of this type of research approach, namely Robert Yin, Robert Stake, and Sharan Merriam. The article additionally addresses the significance of the case study. The paper focuses on the types of case studies and basic recommendations that novice researchers may apply to systemically examine the underlying issues, patterns, or dynamics of a particular subject or case using a holistic approach. In light of the fact that case studies usually concentrate on specific instances, the article advises rookie investigators not to generalize the findings of case studies. In this article, numerous characteristics of case studies are examined, with a focus on its use as a separate qualitative inquiry and research approach.
