Accessing the world's oceans is essential for monitoring and sustainable management of the maritime domain. Difficulty in reaching remote locations has resulted in sparse coverage, undermining our capacity to deter illegal activities and gather data for physical and biological processes. Uncrewed Surface Vessels (USVs) have existed for over two decades and offer the potential to overcome difficulties associated with monitoring and surveillance in remote regions. However, they are not yet an integral component of maritime infrastructure. We analyse 15 years of non-autonomous and semi-autonomous USV-related literature to determine the factors limiting technological diffusion into everyday maritime operations. We systematically categorised over 1,000 USV-related publications to determine how government, academia and industry sectors use USVs and what drives their uptake. We found a striking overlap between these sectors for 11 applications and nine drivers. Low cost was a consistent and central driver for USV uptake across the three sectors. Product ‘compatibility' and lack of ‘complexity' appear to be major factors limiting USV technological diffusion amongst early adopters. We found that the majority (21 of 27) of commercially available USVs lacked the complexity required for multiple applications in beyond the horizon operations. We argue that the best value for money to advance USV uptake is for designs that offer cross-disciplinary applications and the ability to operate in an unsheltered open ocean without an escort or mothership. The benefits from this technological advancement can excel under existing collaborative governance frameworks and are most significant for remote and developing maritime nations.

Journal of Marketing Education ( JMED) is an important academic source for the progression of innovative research and experiential wisdom, both of which enhance the knowledge of marketing educators. The primary objective of this study is to provide a retrospection on the emergence and growth of JMED using scientometrics—in simple terms, is the quantification of science. Applying bibliometric methods, the top articles, authors, and topics in JMED titles are identified. A thematic analysis groups JMED articles into 10 semantic clusters: team environment, innovative teaching techniques, students’ evaluation of teaching, qualitative assessment of marketing outlets, technological diffusion in marketing education, experiential learning, marketing values and ethics, self-regulated learning, objective exams, and multiple experiential techniques and student learning. Among these, technological diffusion in marketing education, marketing values and ethics, and multiple experiential techniques and student learning are the most popular and evolving. Apart from informing JMED readers about possible future avenues of the journal, this study may provide valuable information to its editorial board.

In this chapter, the authors mention, briefly, the attempts made from the 1970s to today to insert modern technologies in the teaching/learning of mathematics. They start with the first pocket calculators in the 1970s, which had a rapid technological diffusion that still exists. They focus on the impact that digital electronic technology has had on teaching/learning math. They will not follow a strictly chronological order, preferring to dwell on what, in their opinion, are the fundamental stages. So, the advent of the PC and programming languages—Logo, Basic, Pascal—CAI programs, DGS software, CAS. They conclude with their MatCos Project, after mentioning the new coding languages, including Scratch.
