Higher Education\u27s Greatest Current Opportunity and Responsibility

Preparing the next generation of teachers at all levels from kindergarten through college is higher education’s greatest current opportunity. Getting it right may be our greatest challenge. The face of science and technology is by definition changing constantly. Today, many feel that the most important work in science is going on increasingly at and across the interfaces of the traditional discipline. To serve our society well, education in the sciences, mathematics, engineering, and technology must change accordingly. In my view, curricula at all levels (K-16) too often continue to reflect only the narrow traditional disciplinary approaches that science has taken in the past, in part due to the existing political structures within academe. Teachers should both appreciate and have understanding of the interdisciplinarity of scientific thought and technological application. I propose that the preparation of all future elementary school teachers contain an interdisciplinary emphasis encompassing all the sciences including mathematics; and that middle and high school science and mathematics teachers’ training be largely interdisciplinary in nature as well

The stewardship of things: Property and responsibility in the management of manufactured goods

In the context of broad-based concerns about the need to move towards a more sustainable materials economy, particularly as they are expressed in debates around ecological modernisation (EM), we argue that product stewardship has radical potential as a means to promote significant change in the relationship between society and the material world. We focus on two important dimensions that have been neglected in approaches to product stewardship to date. Firstly, we argue that immanent within the basic concept of stewardship is a problematisation of dominant understandings of property ownership in neoliberal market economies. In the space opened up by notions of stewardship, different ways of enacting both rights and responsibilities to products and materials emerge which have potential to advance the sustainability of material economies. Secondly, through exploration of existing expressions of product stewardship, we uncover a neglected scale of action. Both policy and dominant articulations of EM focus primarily on the efficiency of production processes; and secondarily, the attitudes and behaviours of individual consumers. Missing from this is the 'meso-scale' of social collectives including households, neighbourhoods, more distributed communities and small scale social enterprises. Based on a review of existing research from Australia and the UK, including our own, we argue that understanding of embedded practices of material responsibility at the household scale can both reinvigorate the concept of product stewardship as a potentially radical intervention, and reveal the potential of the meso-scale as a challenging but worthwhile realm of policy intervention

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

Cruel Britannia: a personal critique of nursing in the United Kingdom

The United Kingdom (UK) once led the world in nursing but because of the exigencies of the funding mechanisms of the National Health Service (NHS), it has fallen a long way behind other countries. We aim to raise awareness inside and outside the UK about the decline in nursing as a profession there. We are purposely contentious, in an attempt to raise questions, both for the UK and for countries which are recruiting British nurses who are leaving because of job losses caused by the funding crisis in the NHS. This paper discusses where the problems that have led to the decline have come from, where nursing is going and poses questions for the future. We hope that the UK government and those who influence the development of nursing will bring it back to the standard it once bad

Noise suppression characteristics of peripherally segmented duct liners

The acoustic fields and transmission losses produced in semi-infinite circular ducts with peripherally segmented liners are analyzed using a series expansion of hard-wall duct modes. The coefficients of the series are computed using Galerkin's method. Unlike finite element approaches, this analysis includes the effects of realistic sources and the number of peripheral strips need not be small. It is shown that peripherally segmented liners redistribute the acoustic energy in waves composed of only a single circumferential mode at the source into other waves which contain a multitude of circumferential modes in the lined section. The accuracy of eigenfunctions computed from the analysis was observed to increase as either the frequency or radial mode order increased. The transmission losses were found to be accurate at frequencies above the cut-on value of the first-order radial mode in a hard-wall duct. The results show that for plane wave sources, peripherally segmented liners may attenuate as much sound as an optimized uniform liner at the optimal point while giving more noise suppression at most other frequencies

A method for determining acoustic-liner admittance in ducts with sheared flow in two-cross-sectional directions

A method is developed for determining the acoustic admittance of a test liner installed in the wall of a grazing flow impedance tube. The mean flow is permitted flow gradients in both cross-sectional directions of the tube. The unknown admittance value is obtained by solving an eigenvalue problem. This eigenvalue problem results from the application of the finite-element method to the partial differential equation and boundary conditions governing the acoustic field. The credibility of the method is established by comparing results with exact solutions obtained for a constant mean-flow profile and with previous results for cases involving shear in only one cross-sectional direction. Excellent comparisons are obtained in both cases. The analysis is used in conjunction with a limited amount of experimental data and shows that the flow must be accurately modeled in order to determine the acoustic-liner properties
