Abstract

Vector potential formulations of Maxwell’s equations need to be gauged, otherwise nodally based finite element approximations lead to an ill conditioned linear system. In this paper alternative Lorentz gauge formulations will be analysed. Particular attention will be paid to the conditions to be applied at material interfaces, bearing in mind ease of implementation in a finite element code and efficiency of solution. The methods discussed are designed to cope with the most challenging physical situations, namely, multiply connected abutting conductors made of different materials.

Abstract

Multinational enterprises (MNEs) in the agri-food sector are continuously transforming their global value chains (GVCs) to address sustainable development challenges of food security (SDG2) and climate change (SDG13). However, the central role of non-governmental organisations (NGOs) in (re)creating GVCs across multilevel stakeholders through innovative approaches to solve sustainability challenges remains under investigated. This explorative study investigates how international NGOs influence the transformation of large-scale industrial animal agriculture to a more sustainable (cell-based) agri-food GVC. The authors conducted a case study on the Good Food Institute (GFI), an international NGO, that has been an active player in the transition to alternative sources of protein to solve animal-based agriculture sustainability issues. The results show that an international NGO can contribute to the transition to a more sustainable GVC and can enhance the GVC’s innovation capabilities.

Abstract

Although edge elements satisfactorily solve the eddy current problem, formulations allowing the use of standard, node‐based elements, are still looked for. But “well‐posed” formulations have been elusive up to now. We propose one, based on a particular gauge, div(σ α)=−σ 2μ v, close to the “Lorenz gauge” of several recent publications, but not identical if one does not assume a piecewise uniform conductivity.

Abstract

In this paper, a hybrid formulation for solving time harmonic eddy current problems in terms of magnetic field h is considered. In particular, we discuss some properties of the implicit boundary condition on the discrete level and the computation of the integral operator exploited in this context. An iterative technique is confirmed to be efficient in solving the arising, partly dense, complex linear system of equations. Furthermore, some test results, including timings for linear solvers are presented.

Abstract

Towns and cities across Canada face rapidly changing economic circumstances and many are turning to a variety of strategies, including tourism, to provide stability in their communities. Community Economic Development (CED) has become an accepted form of economic development, with recognition that such planning benefits from a more holistic approach and community participation. However, much of why particular strategies are chosen, what process the community undertakes to implement those choices and how success is measured is not fully understood. Furthermore, CED lacks a developed theoretical basis from which to examine these questions. By investigating communities that have chosen to develop their tourism potential through the use of murals, these various themes can be explored. There are three purposes to this research: (1) to acquire an understanding of the “how” and the “why” behind the adoption and diffusion of mural-based tourism as a CED strategy in rural communities; (2) to contribute to the emerging theory of CED by linking together theories of rural geography, rural change and sustainability, and rural tourism; and (3) to contribute to the development of a framework for evaluating the potential and success of tourism development within a CED process.

Two levels of data collection and analysis were employed in this research. Initially, a survey of Canadian provincial tourism guides was conducted to determine the number of communities in Canada that market themselves as having a mural-based tourism attraction (N=32). A survey was sent to these communities, resulting in 31 responses suitable for descriptive statistical analysis, using Statistical Package for the Social Sciences (SPSS). A case study analysis of the 6 Saskatchewan communities was conducted through in-depth, in person interviews with 40 participants. These interviews were subsequently analyzed utilizing a combined Grounded Theory (GT) and Content Analysis approach.

The surveys indicated that mural development spread within a relatively short time period across Canada from Chemainus, British Columbia. Although tourism is often the reason behind mural development, increasing community spirit and beautification were also cited. This research demonstrates that the reasons this choice is made and the successful outcome of that choice is often dependent upon factors related to community size, proximity to larger populations and the economic (re)stability of existing industry. Analysis also determined that theories of institutional thickness, governance, embeddedness and conceptualizations of leadership provide a body of literature that offers an opportunity to theorize the process and outcomes of CED in rural places while at the same time aiding our understanding of the relationship between tourism and its possible contribution to rural sustainability within a Canadian context. Finally, this research revealed that both the CED process undertaken and the measurement of success are dependent upon the desired outcomes of mural development. Furthermore, particular attributes of rural places play a critical role in how CED is understood, defined and carried out, and how successes, both tangible and intangible, are measured.

Abstract

Benchmark problem 5 of the TEAM workshops consists of four aluminium blocks placed in the space between the jaws of an electromagnet. Three dimensional eddy currents are induced by 50 Hz time‐varying flux. Eleven sets of results from nine groups of contributors are compared with experimental measurements. The results from most of the computer codes tend to converge to common limits. These limits are in some places slightly different from some of the measured results. The reason for this discrepancy is thought to be due to the idealised boundary conditions, ignoring any losses in laminated iron, which are assumed in all the computer models.

Abstract

Sorts by theme cases involving ethical dilemmas and actions taken in each as described by 23 practising US school administrators in responses to a questionnaire: the majority involved issues of teacher competence. The ethical orientation of the administrators was found to be normally distributed with respect to the five‐level Van Hoose and Paradise model. Only one administrator demonstrated all six components of the moral reasoning described by Howe (1986); most lacked the courage to act on the resolution they preferred. Discusses implications for the selection and training of school administrators.

Abstract

Purpose

In this paper we (a pracademic, a practitioner, and an academic) aim to explore the academic/practitioner gap in social marketing and offer recommendations to close it, while amplifying existing examples of best practice from within the field. We also propose a research agenda to spur dialog and guide further investigations in this area. Insights from prior research, coupled with the co-authors’ experience and observations, indicate that a disconnect does exist between academia and practice within social marketing, though it is admittedly and unsurprisingly not uniform across contexts and disciplinary areas. Given social marketing’s identity as a practice-oriented field, there are many existing examples of academic/practitioner collaboration and the successful linkage of theory and practice that deserve to be amplified. However, the challenges associated with the very different systems and structures affecting both worlds mean the disconnect is problematic enough to warrant systematic change to ensure the two worlds are more aligned.

Design/methodology/approach

This paper (a pracademic, a practitioner and an academic) explores the academic/practitioner gap in social marketing and offer recommendations to close it, while amplifying existing examples of best practice from within the field. The authors also propose a research agenda to spur dialog and guide further investigations in this area.

Findings

The authors suggest five key reasons that focus should be placed upon closing the academic/practitioner gap in social marketing: demonstrating societal value by contributing to practice; embedding and developing theories in practice; adding to the social marketing literature; contributing to social marketing teaching; and communicating the value and effectiveness of social marketing. To close the gap, the authors propose specific recommendations within four broad areas: marketing the academia and practitioner collaboration offer; building ongoing relationships; creating collaborative partnerships; and changing the publishing model ensuring communications are accessible to all. They also suggest ways for social marketing associations and peak bodies to play a role.

Originality/value

The concept of a disconnect between academia and practice is by no means new; it has been a pervasive issue across disciplines for decades. However, this issue has not been the subject of much discussion within the social marketing literature. Recommendations outlined in this paper serve as a starting point for discussion. The authors also acknowledge that due to long standing “bright spots” in the field, numerous examples currently exist. They place an emphasis upon highlighting these examples while illuminating a path forward.
