Abstract

Purpose

This paper aims to explore the potential of ultrasonic additive manufacturing (UAM) to incorporate the direct printing of electrical materials and arrangements (conductors and insulators) at the interlaminar interface of parts during manufacture to allow the integration of functional and optimal electrical circuitries inside dense metallic objects without detrimental effect on the overall mechanical integrity. This holds promise to release transformative device functionality and applications of smart metallic devices and products.

Design/methodology/approach

To ensure the proper electrical insulation between the printed conductors and metal matrices, an insulation layer with sufficient thickness is required to accommodate the rough interlaminar surface which is inherent to the UAM process. This in turn increases the total thickness of printed circuitries and thereby adversely affects the integrity of the UAM part. A specific solution is proposed to optimise the rough interlaminar surface through deforming the UAM substrates via sonotrode rolling or UAM processing.

Findings

The surface roughness (Sa) could be reduced from 4.5 to 4.1 µm by sonotrode rolling and from 4.5 to 0.8 µm by ultrasonic deformation. Peel testing demonstrated that sonotrode-rolled substrates could maintain their mechanical strength, while the performance of UAM-deformed substrates degraded under same welding conditions ( approximately 12 per cent reduction compared with undeformed substrates). This was attributed to the work hardening of deformation process which was identified via dual-beam focussed ion beam–scanning electron microscope investigation.

Originality/value

The sonotrode rolling was identified as a viable methodology in allowing printed electrical circuitries in UAM. It enabled a decrease in the thickness of printed electrical circuitries by ca. 25 per cent.

Abstract

The concept of utilising greenspace to promote and maintain mental health predates the development of almost all current treatment modalities. Although the use of greenspace as a therapeutic tool decreased throughout the 20th century, research in this area has grown exponentially over the last 20 years. This review examines the theory and increasing evidence base behind the psychological, social and physical health benefits of viewing and interacting with greenspace, and considers some of the common methodological limitations within the literature.Those who use secondary and tertiary care mental health services typically experience secondary problems due to reduced levels of social and physical activity. This review argues that the holistic benefits of greenspace make ecotherapy particularly appropriate for such a population. The review recommends that the effects of ecotherapy on those who use secondary and tertiary mental health care services be explored as part of an effort to redress the absence in the literature of quality studies in this area for this population.

Abstract

Purpose

New Space activities offer benefits for human progress and life beyond the Earth. However, there is a risk that the New Space Economy may develop according to an anthropocentric mindset favouring human progress and survival at the expense of all other species and the environment. This mindset raises concerns over the social and environmental impacts of space activities and the accountability of space actors. This research article explores the accountability of space actors by presenting a pluralistic accountability framework to understand, inspire and change accountability in the New Space Economy. This study also identifies future research opportunities.

Design/methodology/approach

This paper is a reflective and normative essay. The arguments are developed using contemporary multidisciplinary academic literature, publicly available evidence and examples. Further, the authors use Dillard and Vinnari's accountability framework to examine a pluralistic accountability system for space businesses.

Findings

The New Space Economy requires public and private entities to embrace hybrid and pluralistic accountability for their social and environmental impacts. A new way of seeing the relationship between human life, the Earth and celestial space is needed. Accounting language is used to mirror and mobilise broader forms of responsibility in those involved in space.

Originality/value

This paper responds to the AAAJ's special issue call for examining how accountability can be ensured in the New Space Age. The space activities businesses conduct, and the anthropocentric view inspiring their race toward space is concerning. Hence, the authors advocate the need for rethinking accountability between humans and nature. The paper contributes to fostering the debate on social and environmental accounting and the accountability of space actors in the New Space Economy. To this end, the authors use a pluralistic accountability framework to help understand how the New Space Economy can face the risks emanating from its anthropocentric mindset.

Abstract

MID‐OCTOBER sees the activities of the library world in full swing. Meetings, committee discussions, schools at work, students busy with December and May examinations in view, and a host of occupations for the library worker. This year—for in a sense the library year begins in October—will be a busy one. For the Library Association Council there will be the onerous business of preparing a report on State Control; for libraries there will be the effort to retain readers in a land of increasing employment and reduced leisure; and for the students, as we have remarked in earlier issues, preparations for the new syllabus of examinations which becomes operative in 1938. It is a good month, too, to consider some phases of library work with children, “which,” to quote the L.A. Resolutions of 1917, “ought to be the basis of all other library work.”

Abstract

Purpose

The purpose of this study is to examine the trend toward purchasing locally grown food and evaluate if tourists visiting Hawai'i are willing to pay more for locally produced foods that are more ecologically sustainable.

Design/methodology/approach

A research questionnaire was developed in order to investigate the attitudes and behaviors of tourists from the continental United States visiting Hawai'i in purchasing locally grown food in Hawai'i. The final sample includes 454 valid survey responses collected via Momentive, a market research services company.

Findings

According to the findings of this study, there are economic prospects to expand the use of locally cultivated food into the tourists' experience, as well as a willingness for tourists to support these activities financially. The Contingent Valuation study revealed that tourists from the continental United States were ready to pay a higher price to purchase food that is locally grown, signifying that tourists to Hawai'i are willing to aid the local agriculture business by increasing their restaurant/hotel meal bill, which will help Hawai'i become a more sustainable tourist destination.

Research limitations/implications

While tourists from the United States mainland, which is the “an islands” top tourist market, have agreed with paying extra or an additional fee for locally grown food products, this study might not accurately represent the attitudes and behaviors of international tourists visiting Hawai'i. Future research should focus on the international tourist markets which may have different social norms or cultural differences thus could provide a broader spectrum of the current study's findings.

Originality/value

The results of this study provided quantitative evidence that tourists from the United States are interested in purchasing locally grown food items in Hawaii in addition to their willingness to pay an additional fee for these locally grown food products at a restaurant or a hotel dining room, thus addressing a gap in the tourism research.

Abstract

Purpose

The project “Public schools in change – collaboration as a resource” was aimed to strengthen professional capital (social- human- and decision-capital) in public schools and as a part of this to strengthen collaboration within teams. The purpose of this paper is to focus on the approach of linking development of professional capital to the development of team competence through facilitating and discuss the adequacy of the methods used to fulfil the purpose.

Design/methodology/approach

This study was designed as a multiple case intervention implemented at four worksites. It was organized as a course consisting of four sessions among 15–20 team coordinators from each school unit. The research group provided insights and methods to increase the team’s ability to manage tasks and cooperate.

Findings

Based on observations of team meetings, the study provides a discussion on the usefulness of the approach of linking team competence and professional capital. Both at theoretical and practical levels, the study finds it is meaningful to combine facilitating as methods to ensure the creation of value in organizational teamwork, in general, with the concept of professional capital pointing on the quality of the core task and particularly developed within an educational context.

Research limitations/implications

The study provide a presentation of two theoretical frameworks and a discussion of the adequacy of linking these frameworks to the development of team competences in a school context.

Practical implications

The study suggests that organizations and educational institutions (of teachers, physicians, and social workers) may benefit from linking professional capital and facilitating and thereby provide employees and students training in professional collaboration.

Social implications

In a still more complex society, collaboration is crucial. The study suggests ways to improve collaboration, quality of the core task along with the relational dimensions in the psychosocial work environment.

Originality/value

Development of professional capital through increased team competences and facilitating skills represents a new and promising approach with theoretical as well as practical implications within a school context. Indeed, not only school teams but also teams in other organizations dealing with social- task- and contextual complexity can benefit from the insights and experiences of this study.
