The Delphi: An Underutilized Method of Scholarly and Practical Research for a Public Relations Field in Transition

This paper introduces, analyzes, and explains the Delphi method of research, particularly as it applies to certain aspects of the public relations industry. The Delphi technique became known some fifty years ago when the Rand Corporation used it extensively for forecasting. Since then, scholars and forecasters have used it periodically for early, qualitative explorations into complex issues or domains. The overall purpose of the Delphi is to facilitate formal discussion among selected experts in a given domain around a particular topic; it is particularly useful when those experts cannot easily come together in one place. The method encourages the sharing of diverging worldviews over a few “rounds” or iterations in the hope that the views may converge into some direction around the given topic. For this reason, the Delphi has often been used in situations or environments that tend to be somewhat ambiguous and where interviews and surveys are neither timely nor appropriate. Public relations scholars started incorporating the Delphi method into their research in the late 1980s, and the technique has since been employed to explore broad-ranging issues among experts on at least seven or eight occasions. It has also been used to explore ethical norms. However, public relations literature contains little discussion about the technique and its possible applications or implications for developing knowledge in the field. This paper, then, is intended to dissect the Delphi method so as to offer guidance to public relations scholars who may wish to use it in future studies. The authors, both of whom have conducted Delphi studies, believe that the method is valuable in examining topics that are emerging or underdeveloped in the field; however, certain precautions are necessary in order to ensure that the research achieves the desired effects. The paper is created through a literature review of similar articles on Delphi studies in other domains, notably health communications, followed by an examination of some studies conducted to advance issues in public relations. The authors explore the most appropriate situations for using a Delphi and list the benefits and disbenefits of different aspects or applications of the method. They trace the evolution of Delphi research from its early roots into the era of the Internet and social media, which offer new tools for increasing the number of respondents and moving through the Delphi process more quickly than could previously be done. In advancing such an examination of the Delphi, this paper should be a useful addition to emerging public relations literature

Vowel Trigrams

In the August and November 1969 Word Ways, Ross and Faith Eckler presented a list of common trigrams that can be found in English words. They deserve congratulations, along with their helpers, for undertaking what, initially, must have appeared to be a Herculean task. They managed to track down 6,500+ of the 17,576 possible trigrams

The Anthropocene crisis and higher education: A fundamental shift

This article seeks to address a fundamental shift that has occurred in reality; a displacement that requires us to critically account for the ways in which knowledge is both being produced and taught at universities. The recent re-naming of the current geological epoch after anthropos has some chilling implications for humans and the ecosystems on which their livelihoods depend. As pedagogues, the crisis of the Anthropocene demands that we make drastic interventions in the way we teach and in what we teach. My aim is to suggest ways in which Deleuzoguattarian schizoanalysis, intersecting as it does with critical posthumanism, the affective turn and the new materialisms, might assist us in this process of crafting socially and environmentally-just pedagogies that are relevant to the contemporary situation. In so doing, I will address some of the uncanny ethical, ontological, epistemological and affective configurations of these theoretical perspectives to show how these ideas may impact the curriculum of socially/environmentally just pedagogies and the practice of such pedagogies in higher education.DHE

Improved precision with Hologic Apex software.

UnlabelledThe precision of Hologic Apex v2.0 analysis software is significantly improved from Hologic Delphi v11.2 software and is comparable to GE Lunar Prodigy v7.5 software. Apex and Delphi precisions were, respectively, 1.0% vs. 1.2% (L1-L4 spine), 1.l % vs. 1.3% (total femur), 1.6% vs. 1.9% (femoral neck), and 0.7% vs. 0.9% (dual total femur).IntroductionPrecision of bone mineral density (BMD) measurements by dual-energy X-ray absorptiometry (DXA) is known to vary by manufacturer, model, and technologist. This study evaluated the precision of three analysis versions: Apex v2.0 and Delphi v11.2 (Hologic, Inc.), and Prodigy v7.5 (GE Healthcare, Inc.) independent of technologist skill.MethodsDuplicate spine and dual hip scans on 90 women were acquired on both Delphi and Prodigy DXA systems at three clinics. BMD measures were converted to standardized BMD (sBMD) units. Precision errors were described as a root-mean-square (RMS) standard deviations and RMS percent coefficients of variation across the population.ResultsApex and Delphi values were highly correlated (r ranged from 0.90 to 0.99). Excluding the right neck, the Apex precision error was found to be 20% to 25% lower than the Delphi (spine: 1.0% versus 1.2% (p < 0.05), total hip: 1.1% versus 1.3% (p < 0.05), right neck: 2.3% versus 2.6% (p > 0.1)). No statistically significant differences were found in the precision error of the Apex and Prodigy (p > 0.05) except for the right neck (2.3% versus 1.8% respectively, p = 0.03).ConclusionThe Apex software has significantly lower precision error compared to Delphi software with similar mean values, and similar precision to that of the Prodigy
