The characteristics of the Internet of Things (IoT) are such that traditional models of trust developed within interpersonal, organizational, virtual and information systems contexts may be inappropriate for use within an IoT context. The purpose of this paper is to offer empirically generated understandings of trust within potential IoT applications.

In an attempt to capture and communicate the complex and all-pervading but frequently inconspicuous nature of ubiquitous technologies within potential IoT techno-systems, propositions developed are investigated using a novel mixed methods research design combining a videographic projective technique with a quantitative survey, sampling 1,200 respondents.

Research findings suggest the dimensionality of trust may vary according to the IoT techno-service context being assessed.

The contribution of this paper is twofold. First, and from a theoretical perspective, it offers a conceptual foundation for trust dimensions within potential IoT applications based upon empirical evaluation. Second, and from a pragmatic perspective, the paper offers insights into how findings may guide practitioners in developing appropriate trust management systems dependent upon the characteristics of particular techno-service contexts.

This paper explores the historical roots of accounting for biodiversity and extinction accounting by analysing the 18th-century Naturalist's Journals of Gilbert White and interpreting them as biodiversity accounts produced by an interested party. The authors aim to contribute to the accounting history literature by extending the form of accounting studied to include nature diaries as well as by exploring historical ecological accounts, as well as contributing to the burgeoning literature on accounting for biodiversity and extinction accounting.

The authors’ method involves analysing the content of Gilbert White's Naturalist's Journals by producing an 18th-century biodiversity account of species of flora and fauna and then interpretively drawing out themes from the Journals. The authors then provide a Whitean extinction account by comparing current species' status with White's biodiversity account from 250 years ago.

This paper uses Gilbert White's Naturalist's Journals as a basis for comparing biodiversity and natural capital 250 years ago with current species' status according to extinction threat and conservation status. Further the paper shows how early nature diary recording represents early (and probably the only) forms of accounting for biodiversity and extinction. The authors also highlight themes within White's accounts including social emancipation, problematisation, aesthetic elements and an example of an early audit of biodiversity accounting.

There are limitations to analysing Gilbert White's Naturalist's Journals given that the only available source is an edited version. The authors therefore interpret their data as accounts which are indicative of biodiversity and species abundance rather than an exactly accurate account.

From the authors’ analysis and reflections, the authors suggest that contemporary biodiversity accounting needs to incorporate a combination of narrative, data accounting and pictorial/aesthetic representation if it is to provide a rich and accurate report of biodiversity and nature. The authors also suggest that extinction accounting should draw on historical data in order to demonstrate change in natural capital over time.

Social implications include the understanding gleaned from the authors’ analysis of the role of Gilbert White as a nature diarist in society and the contribution made over time by his Journals and other writings to the development of nature accounting and recording, as well as to one’s understanding and knowledge of species of flora and fauna.

To the authors’ knowledge this is the first attempt to analyse and interpret nature diaries as accounts of biodiversity and extinction.

The National Association for Professional Development Schools (NAPDS) recognizes that there is a tendency for the term “PDS” (Professional Development School) to be used as a catch-all for various relationships that constitute school–university partnership work. The intent of this NAPDS statement is to assert the essentials, or fundamental qualities, of a PDS. NAPDS encourages all those working in school–university relationships to embrace the Nine Essentials of PDSs communicated in this statement. The Essentials are written in tangible, rather than abstract, language and represent practical goals toward which work in a PDS should be directed.

Policy statement.

NAPDS maintains that these Nine Essentials need to be present for a school-university relationship to be called a PDS. Without having all nine, the relationship that exists between a school/district and college/university, albeit however strong, would not be a PDS. How individual PDSs meet these essentials will vary from location to location, but they all need to be in place to justify the use of the term “PDS.”

For those in established PDSs, some aspects of this document will be confirmed, while other aspects may be identified as needing attention. For those aspiring to establish PDSs, the authors offer this statement as a useful guide for their work. NAPDS invites individuals involved in school–university partnerships to share this statement with colleagues in the spirit of continuous improvement. By coming to terms with the challenges and opportunities inherent in this statement, the study can collectively fulfill the vision of this remarkable and distinct partnership called PDS.

This policy statement articulates how the Nine Essentials are the foundation of PDS work.
