Why be first if it doesn’t pay? The case of early adopters of C-TPAT supply chain security certification

Purpose The purpose of this paper is to focus on adoption of certified management standards, specifically public standards. Such standards play an increasingly important role in today’s business environment. However, to generate adoption benefits, they must be first widely accepted – a situation where they have become viewed as the de facto norms. For this state to occur early adopters play a critical role. Past research has argued that early adopters, in exchange for assuming more risk, are rewarded with higher economic returns. Yet, these findings are based on private, not public standards. With public standards, early adopters do not receive such benefits. There is evidence that public standards are becoming more important. This situation leads to a simple but important question addressed in this study – if early adopters assume the risks of embracing a new public standard without economic benefits, then what is their motivation? To resolve this question, this study draws on agency theory and prospect theory. The authors argue that early adopters embrace such standards because of their desire to minimize risk resulting from failure to support the goal at the heart of the public standards. Design/methodology/approach Data were obtained from the Customs-Trade Partnership Against Terrorism (C-TPAT) Partners Cost Benefit Survey and analyzed through structural equation modeling. Findings Early adopters of public standards are not driven by economic benefits but rather by the need to minimize their exposure to the risks associated with failing to satisfy the goals associated with a public standard. In other words, they were motivated by the need to minimize costs. In the case of C-TPAT, these costs are those of failing to provide or improve network security. Research limitations/implications This study has shed new light on the standards adoption process by clarifying the specific motivations that drive early adoption of a public standard. In addition to identifying the loss aversion motives of early adopters and economic benefit motives of later adopters, the authors have also elaborated on the notion that standards have differing levels of precedence, particularly when comparing private with public standards. Practical implications In a world characterized by increasing demands for outcomes such as improved security and where governmental funding is falling, due to growing deficits and governments that are becoming more conservative, the authors expect the use of public standards to increase. Originality/value Different from prior research on private standard, the paper focuses on the organizations involved in the adoption and diffusion of a public standard, with special attention being devoted to the early adopters. The paper provides a theoretical explanation for the actions of early adopters of a public standard through the theoretical lens of prospect theory

Autonomous, Collaborative, Unmanned Aerial Vehicles for Search and Rescue

Search and Rescue is a vitally important subject, and one which can be improved through the use of modern technology. This work presents a number of advances aimed towards the creation of a swarm of autonomous, collaborative, unmanned aerial vehicles for land-based search and rescue. The main advances are the development of a diffusion based search strategy for route planning, research into GPS (including the Durham Tracker Project and statistical research into altitude errors), and the creation of a relative positioning system (including discussion of the errors caused by fast-moving units). Overviews are also given of the current state of research into both UAVs and Search and Rescue

CHORUS Deliverable 2.1: State of the Art on Multimedia Search Engines

Based on the information provided by European projects and national initiatives related to multimedia search as well as domains experts that participated in the CHORUS Think-thanks and workshops, this document reports on the state of the art related to multimedia content search from, a technical, and socio-economic perspective. The technical perspective includes an up to date view on content based indexing and retrieval technologies, multimedia search in the context of mobile devices and peer-to-peer networks, and an overview of current evaluation and benchmark inititiatives to measure the performance of multimedia search engines. From a socio-economic perspective we inventorize the impact and legal consequences of these technical advances and point out future directions of research

Software-Defined Lighting.

For much of the past century, indoor lighting has been based on incandescent or gas-discharge technology. But, with LED lighting experiencing a 20x/decade increase in flux density, 10x/decade decrease in cost, and linear improvements in luminous efficiency, solid-state lighting is finally cost-competitive with the status quo. As a result, LED lighting is projected to reach over 70% market penetration by 2030. This dissertation claims that solid-state lighting’s real potential has been barely explored, that now is the time to explore it, and that new lighting platforms and applications can drive lighting far beyond its roots as an illumination technology. Scaling laws make solid-state lighting competitive with conventional lighting, but two key features make solid-state lighting an enabler for many new applications: the high switching speeds possible using LEDs and the color palettes realizable with Red-Green-Blue-White (RGBW) multi-chip assemblies. For this dissertation, we have explored the post-illumination potential of LED lighting in applications as diverse as visible light communications, indoor positioning, smart dust time synchronization, and embedded device configuration, with an eventual eye toward supporting all of them using a shared lighting infrastructure under a unified system architecture that provides software-control over lighting. To explore the space of software-defined lighting (SDL), we design a compact, flexible, and networked SDL platform to allow researchers to rapidly test new ideas. Using this platform, we demonstrate the viability of several applications, including multi-luminaire synchronized communication to a photodiode receiver, communication to mobile phone cameras, and indoor positioning using unmodified mobile phones. We show that all these applications and many other potential applications can be simultaneously supported by a single lighting infrastructure under software control.PhDElectrical EngineeringUniversity of Michigan, Horace H.
