Abstract

Purpose

Many psychiatrists and trainees in Aotearoa New Zealand used telepsychiatry during COVID-19 lockdowns, despite minimal experience and training in the area. Research on a culturally safe telepsychiatry framework is lacking in Aotearoa. This study aims to provide a better understanding of telepsychiatry in the Aotearoa context and identify potential gaps with the current practice, with a focus on exploring telepsychiatry use with Maori, Pacific peoples and Asians.

Design/methodology/approach

This qualitative study was guided by the principles of the Kaupapa Maori methodology and the “Give Way Rule” from Pan-Pacific studies, to ensure culturally appropriate analysis and outcomes. Semi-structured interviews were conducted with a sample of psychiatrists and trainees recruited from Aotearoa members of the Royal Australian and New Zealand College of Psychiatrists. The qualitative data were then analysed using general inductive thematic analysis to identify the major themes.

Findings

In total, 18 participants were interviewed. Three key themes were identified: cultural safety such as preparation for a telepsychiatry session, cultural practices and equity issues; clinical practice such as continuity of care, patient selection and limitations; and process of running a telepsychiatry service.

Originality/value

The analysis of the main themes gives both practical ideas for providing a culturally safe telepsychiatry appointment, as well as a wider base for developing a telepsychiatry service that works particularly for Maori, Pacific and Asians mental health users. Issues around resources and expertise in the field are lacking and further frameworks to support infrastructure and training are needed.

Abstract

Purpose

The purpose of this paper is to present a new collaborative design-based method for designing customized garments, aimed at the physically disabled people with scoliosis.

Design/methodology/approach

The proposed method is based on the virtual human model created using a 3D body scanner, permitting to simulate the consumer’s morphological shape with atypical physical deformations. Next, customized 2D and 3D virtual garment prototyping tools will be used to create products through interactions between the consumer, designer and pattern maker. The general principle of the proposed design method is based on the following sequence: design-display-evaluation-adjustment. After running the sequence for a number of times, the final design solution, which will be approved by both the designer and consumer, can be easily identified.

Findings

Design knowledge, which is already applied to normal body shapes successfully can be applied to 3D garment design using the concept which is based on collaborative design. Through this process, the classical 2D garment design knowledge, especially 2D patterns and design rules, can be modified and applied according to a normalized virtual garment sensory evaluation procedure quantitatively. This evaluation procedure, interactively performed by the designer and consumer, can permit to adapt the finished product to disabled people afflicted with severe scoliosis. The proposed method is also validated to be more advanced compared to 2D-to-3D virtual CAD design method, especially for atypical morphologies.

Originality/value

As a co-design method, 3D virtual draping and sensory evaluation can fully satisfy the interaction between the garment design technical space and perceptual space of the finished garments ensuring desired 3D garment fit effect by adjustment of technical parameters. 3D scanning technology is used to generate a complete digitalized 3D human model, permitting to extract the main features of body shapes without accurate measurements. As a knowledge-based design process, both the fashion design knowledge and the pattern making knowledge will be extracted to provide inspirations and references. Successful design solutions will be incorporated into the fashion design knowledge base in order to generate new design rules and enhance professional design knowledge.

Abstract

Purpose

The purpose of this study is to examine relevant demographic and socio-economic factors as they relate to progress towards intercultural communicative competence (ICC) and intercultural sensitivity for ethnic-minority Latinx middle school English learners (ELs) using a mobile-assisted funds-of-knowledge-featured writing practice.

Design/methodology/approach

Through the theoretical lens of funds of knowledge, this three-year study implemented a survey-based quasi-experimental design centered on the Latinx ELs’ ICC development with the implementation of an intercultural sensitivity questionnaire (Chen and Starosta, 2000). The authors first investigated the relationship between ELs’ intercultural sensitivity and associated demographic and socio-economic factors. The authors then examined the changes of ELs’ intercultural sensitivity. Over ten weeks, the intervention group completed five funds-of-knowledge-featured narrative essays using pen and paper and mobile-based writing tools alternatively.

Findings

Findings indicated that ELs’ intercultural sensitivity increased as they advanced to a higher-level grade from sixth to eighth. The embedded mobile-assisted funds-of-knowledge writing practice as intervention promoted ELs’ intercultural sensitivity in interaction engagement, respect of cultural differences, interaction enjoyment and interaction attentiveness. Among the variables, interaction enjoyment was portrayed the most. ELs who reported not speaking English at home were statistically significant in this experiment.

Originality/value

This study acknowledges the robust and variance of funds of knowledge as a niche to address the interculturality and hybridity of ELs’ cultural practices accumulated through Latinx ELs’ family socialization and social development using mobile-assisted writing practice. This study could provide implications for optimizing inclusive experience to promote computer-assisted language learning in a contemporary, postcolonial global world.

Abstract

Purpose

The importance of teacher leadership in enhancing school outcomes is recognized, but there remains a scarcity of research addressing the conditions for principals to nurture such leadership. This study examined how school contextual factors, i.e. faculty trust and academic emphasis, moderate the impact of principals' distributed leadership lon teacher leadership.

Design/methodology/approach

A nationwide survey was conducted among junior high school teachers in Taiwan. The sample encompassed schools from different geographical regions and sizes, yielding a total of 1,340 valid responses. Hierarchical regression analyses were employed to analyze the potential moderating effects of interest.

Findings

There were interactive effects of principals' distributed leadership and school contextual factors on teachers' adoption of leadership roles. The impact of principals' distributed leadership on teacher leadership was amplified in environments marked by elevated levels of trust relations and reduced academic emphasis.

Practical implications

This study uncovers the critical prerequisites principals must address to cultivate teacher leadership. To effectively encourage heightened teacher engagement in leadership, principals must place a premium on nurturing trusting relations with their teaching staff and acknowledge that the influence of their leadership might be lessened in an environment where credentialism holds sway.

Originality/value

The exploration into faculty trust and academic emphasis yields insights into the conducive conditions for principals to foster teacher leadership. The identified attenuating impact of academic emphasis on principal effect within an Asian societal context highlights its significance not only as an organizational property but also as a manifestation of national cultural values.

Abstract

Purpose

An improved simulation model of switched reluctance motor (SRM) for steady-state operation that considers the core losses in the stator and rotor is established to obtain the steady performance of the high-speed SRM during the design, analysis and control of SRM driving system more accurately.

Design/methodology/approach

The transient core loss model for the material and SRM is presented. Then a new method for calculating the flux density of the motor in real time is introduced, and a steady-state simulation model of the SRM including real-time transient core losses calculation model is established according to the transient flux density. Because the transient core losses calculated by above method are the total core losses of the motor, a core losses distribution method is proposed and the steady-state simulation model of the SRM including the distributed core losses’ effect on the phase winding is established.

Findings

The comparison results show that the proposed model has higher accuracy than the traditional model, excluding core losses, especially at the moments when phase voltage is turn-on and turn-off. The proportion of the core losses to the motor losses increases with the increase in speed. So, the core losses’ effect on the steady-state performance of the high-speed SRM cannot be ignored.

Originality/value

The method to obtain flux density in the real time is presented and the improved steady-state simulation model of SRM that considering transient core losses is proposed.

Abstract

Purpose

From the perspective of the institution and internationalization speed, the article discusses the internal mechanism of cross-border e-commerce selection mode, as well as the moderating role of social networks as the intangible resource, and expand the theoretical system of corporate internationalization.

Design/methodology/approach

Based on the empirical data of 456 multinational e-commerce companies in five first-tier cities in China from 2016 to 2019, our research explores the selection mode of cross-border e-commerce.

Findings

The results show that (1) the institutional distance of the host country leads to the exit from cross-border e-commerce platforms in the international expansion of enterprises. (2) The difference in internationalization speed online and offline has become a mediated mechanism for the exit of cross-border e-commerce platforms due to the institutional distance of the host country. (3) The diversity and scale of offline social networks can weaken the impact of differences in internationalization speed on the exit from cross-border e-commerce platforms. (4) The resistance of companies expanding to countries with a weak institutional environment is greater than that experienced when expanding to countries with a strong one.

Originality/value

This study shows, for the first time, how to select expansion mode for cross-border e-commerce. And the paper also centers on the research of the impact of “social network”, a kind of intangible resource, on cross-border e-commerce platform adoption.

Abstract

Purpose

This paper aims to examine how integration modes impact the acquirer knowledge diffusion capacity of overseas mergers and acquisitions (M&As) effected by emerging market firms and the role played by the global innovation network position of the acquiring firms in affecting this relationship.

Design/methodology/approach

Through the use of structural equation modelling and bootstrap testing, the hypotheses are tested by drawing upon a sample of 102 overseas M&As effected by listed Chinese manufacturing companies.

Findings

The results show that acquirers from emerging countries are unable to increase the knowledge diffusion capacity unless they choose the right post-merger integration mode. This paper also finds that the relationship between integration mode and knowledge diffusion is channelled through the centrality and structural holes of acquirers in the global innovation networks. When considering the combinations of different resource similarities and complementarities of the acquired firms, differences emerge in the integration model and network embedded path of acquirers in emerging countries.

Practical implications

Emerging market multinational enterprises should consider post-merger integration as a crucial facilitator to the crafting of global innovation network positions that promote knowledge diffusion. The choices of integration mode and brand management autonomy should be matched with the resource similarities and complementarities that exist between the acquirer and target firms.

Originality/value

Based on the resource orchestration theory and by focussing on network centrality and structural hole as the crucial links, this study provides a nuanced understanding of the relationship between post-merger integration and knowledge diffusion and sheds light on latecomer firms from emerging countries.

Abstract

Purpose

Deglobalization and the coronavirus disease 2019 (COVID-19) pandemic have severely hindered multinational enterprise (MNE) investment. At the same time, digital technology is seriously challenging it with traditional production factor flows. Few studies have realized that the impact of digitalization is not limited to either transaction costs or the location-boundness of firm-specific advantages (FSAs), but extends to profound changes in the fundamental essence of MNEs. There is still limited understanding of this body of knowledge as a whole, including how its subtopics are interrelated. This study took the production factor change perspective to review MNE theory in the digital era. Therefore, this study aims to identify any upcoming and undeveloped themes in order to provide a platform suited to direct future research.

Design/methodology/approach

This paper presents a summary and a review of 151 articles published between 2007 and 2020. Such review was conducted to systematically explain the connotations and influential mechanisms of digital empowerment on MNE theory. This was achieved by using the CiteSpace citation visualization tool to build a keyword co-occurrence network.

Findings

The research findings pertain to how digitalization expands, breaks through, and even reshapes traditional MNE theory from four distinctive angles: the influential factors of internationalization, the process of internationalization, competitive advantage, and location choice. The findings are followed by the presentation of future research directions.

Originality/value

This paper presents an examination of MNE theory in the digital era from the perspective of production factor change. In doing so, it identifies significant theoretical innovation opportunities for future scholarly research priorities.

Abstract

Purpose

This paper aims to analyze the characteristics of friction vibration signals and identify the vibration excitation source at the start and stop stage of microtextured end face of dry gas seals.

Design/methodology/approach

The friction pair consists of a diamond-like carbon (DLC) film microtextured seal ring and a spiral groove seal ring. Friction vibration signal feature extraction method based on harmonic wavelet packet and spectrum analysis was proposed. Signals were collected using acceleration sensor, acquisition card and LabVIEW software. Vibration acceleration signal was decomposed into 32 frequency bands using MATLAB wavelet packet transformation. The 32nd band coefficient was extracted for reconstruction, time-domain and spectral waveforms were obtained and spectra before/after denoising were compared.

Findings

The end face of the DLC film microtextured seal ring generates a good dynamic pressure effect, and the friction and vibration reduction effects are obvious. The harmonic wavelet packet can decompose the vibration signal conveniently and precisely. In the case of this experiment, the frequency of vibration of the seal ring is 7500 HZ.

Originality/value

The results show that the method is effective for the processing of friction vibration signal and the identification of vibration excitation source. The findings will provide ideas for the frictional vibration signal processing and basis for further research in the field of tribology of dry gas seal ring.
