To describe the function and use of the GreenSeeker™ active remote sensor used to detect crop nitrogen status.

In this paper, the GreenSeeker active remote sensor and its use in irrigated maize production systems will be described. A brief discussion of the science of using remote sensing for studying plants is presented. Additionally, a summary of observations collected from field trials is presented.

The GreenSeeker active sensor has tremendous potential for accurately characterizing crop variability for site‐specific N rate determinations in the Western Great Plains region of the United States.

This paper discusses the GreenSeeker active sensor for detecting crop variability. Data from the GreenSeeker can be used to make site‐specific nitrogen fertilizer applications which may lead to improved nitrogen use efficiency.

Business‐model innovation is critical to success in today's increasingly complex and fast‐changing environment. So corporate leaders need to understand when to adapt the business model and how to execute the change. This paper aims to address this issue.

Data from IBM's Global CEO Study 2008 and an analysis of 28 successful business‐model innovators, produced insights into both the best timing and process for business model innovation.

The IBM researchers identified a set of characteristics that strong business‐model innovators demonstrate consistently.

A set of characteristics, which the IBM researchers call the “Three A's,” are critical to the successful design and execution of business‐model innovation: Aligned – Leverage core capabilities and design consistency across all dimensions of the business model, both internally and externally, that build customer value; Analytical – Use information strategically to create foresight, and prioritize actions while measuring and tracking for rapid course correction; and Adaptable – Link innovative leadership with the ability to effect change and institutionalize operational flexibility.

The paper answers two questions that can help companies develop their innovation strategy and transformation approach for the new economic environment: Under what conditions should companies adapt their business model?; and What capabilities and characteristics support the design and execution of successful business‐model innovation?

The positive impact of just‐in‐time (JIT) programmes on production performance is well documented. JIT programmes consist of a number of different elements including change‐over reduction, kanban methods, and preventive maintenance programmes. Some researchers have proposed lists of elements they believe are critical to JIT success. However, there is a lack of consensus among researchers as to which items should be included in the list of critical elements. Reports research, consisting of a survey of manufacturers known to be active in JIT exploration, and an in‐depth case study to improve the understanding of the critical components in JIT programmes. Results from the survey were compared with existing research to determine better the elements critical to JIT success.

It is now forty years since there appeared H. R. Plomer's first volume Dictionary of the booksellers and printers who were at work in England, Scotland and Ireland from 1641 to 1667. This has been followed by additional Bibliographical Society publications covering similarly the years up to 1775. From the short sketches given in this series, indicating changes of imprint and type of work undertaken, scholars working with English books issued before the closing years of the eighteenth century have had great assistance in dating the undated and in determining the colour and calibre of any work before it is consulted.

Mathematics can be a challenging content area for all students and especially for students with disabilities. Assistive technology can support the access, participation and achievement of students with disabilities in mathematics in general and in inclusive mathematics settings in particular. In this chapter, assistive technology to academic and functional mathematics will be discussed; particularly, manipulatives, calculators and other technology-mediated mathematics interventions (e.g., apps or computer programs) will be highlighted.

This is an exploratory study leveraging a domain-specific innovativeness (DSI) perspective to understand adoption of QR code delivered mobile marketing. Specifically, the purpose of this paper is to explore the roles of “innovativeness” and “risk aversion” on QR code adoption and usage in the low-involvement context to address tensions between risk and innovation literatures.

Participants were assigned to “laggard” (n=19) and “innovator/early adopter” (n=19) segments using the DSI scale. A combination of qualitative reductionism (means-end chain analysis) and qualitative holism (semi-structured interviewing) was employed.

Confusion regarding the functionality and purpose of QR codes adversely affected willingness to use and utility perceptions. Source trust and information credibility emerged as key concerns for those considering QR codes, with consumer risk aversion and innovativeness orientations influencing the nature of trust concerns. A perceived lack of complementarity between QR codes and retail environments reduced perceived relevance. For low-involvement products, marketers should consider moving beyond brand-level communication to align offerings to the broader foodscape.

Findings are limited to the low-involvement product context. Although DSI was considered, the impact of technological innovativeness was not explored. Future research may consider the impact of information provision at the broader foodscape rather than product-specific level when exploring QR code applications in the food domain.

This is the first study to explore the role of product category innovativeness, as distinct from technological innovativeness on the acceptance and usage of mobile marketing applications in the low-involvement context. This research builds on existing risk and innovation literatures and addresses tensions between these literatures presented by QR codes within the low-involvement context.

In October 2020, Zambia failed to make a $42.5 million interest payment on $1 billion in Eurobonds maturing in 2024, becoming the first African country to default on its debt obligations in the aftermath of COVID-19. Zambia's default highlights the fragmented nature of governance in sovereign debt markets. The Zambian default also underscores the continuing impact of colonial hangover in former colonies in Africa. Fragmented governance and colonial overhang create incentives for both debtors and creditors that contribute to cycles of sovereign debt. These cycles of debt pose a particular hazard to residents within countries that issue such debt. In African contexts, this has led to flows of funds for debt repayment that may significantly jeopardize the well-being of people who are already poor. Zambia's default also reflects the increasing need of African countries to navigate among different external actors, particularly China, which has given loans throughout Africa for varied projects, including infrastructure lending as part of its Belt and Road Initiative. The Zambian default draws attention to the significant amount of Eurobond debt African countries have incurred in recent years and the burdens that such debt may impose. The circumstances of Zambia's default, as well as recent disputes about external debt in Mozambique, reflect continuing issues about transparency and public scrutiny of sovereign debt transactions and the broader societal impact of debt internally within African countries and in relations between African countries and varied external powers.

The deferred nature of retirement benefits provides public officials with a means of postponing to later years the retirement financing burden. This practice is aided by the fact that the Employee Retirement Income and Security Act of 1974 (ERISA) does not apply to the public sector. Failure to provide for full actuarial funding violates the concept of interperiod equity, which the Governmental Accounting Standards Board cites as a fundamental responsibility of public administrators. Underfunding also violates the just savings principle developed by the philosopher John Rawls. This paper examines the extent of retirement system underfunding in state and local government and considers the various ways in which underfunding imposes an unfair burden on future generations. The ethical significance of underfunding is tied to the works of Rawls, and remedial measures are proposed which are consistent with Rawls’ just savings principle.
