Abstract

Purpose

Identification of the direction of the sound source is very important for human–machine interfacing in the applications such as target detection on military applications and wildlife conservation. Considering its vast applications, this study aims to design, simulate, fabricate and test a bidirectional acoustic sensor having two cantilever structures coated with piezoresistive material for sensing has been designed, simulated, fabricated and tested.

Design/methodology/approach

The structure is a piezoresistive acoustic pressure sensor, which consists of two Kapton diaphragms with four piezoresistors arranged in Wheatstone bridge arrangement. The applied acoustic pressure causes diaphragm deflection and stress in diaphragm hinge, which is sensed by the piezoresistors positioned on the diaphragm. The piezoresistive material such as carbon or graphene is deposited at maximum stress area. Furthermore, the Wheatstone bridge arrangement has been formed to sense the change in resistance resulting into imbalanced bridge and two cantilever structures add directional properties to the acoustic sensor. The structure is designed, fabricated and tested and the dimensions of the structure are chosen to enable ease of fabrication without clean room facilities. This structure is tested with static and dynamic calibration for variation in resistance leading to bridge output voltage variation and directional properties.

Findings

This paper provides the experimental results that indicate sensor output variation in terms of a Wheatstone bridge output voltage from 0.45 V to 1.618 V for a variation in pressure from 0.59 mbar to 100 mbar. The device is also tested for directionality using vibration source and was found to respond as per the design.

Research limitations/implications

The fabricated devices could not be tested for practical acoustic sources due to lack of facilities. They have been tested for a vibration source in place of acoustic source.

Practical implications

The piezoresistive bidirectional sensor can be used for detection of direction of the sound source.

Social implications

In defense applications, it is important to detect the direction of the acoustic signal. This sensor is suited for such applications.

Originality/value

The present paper discusses a novel yet simple design of a cantilever beam-based bidirectional acoustic pressure sensor. This sensor fabrication does not require sophisticated cleanroom for fabrication and characterization facility for testing. The fabricated device has good repeatability and is able to detect the direction of the acoustic source in external environment.

Abstract

Purpose

This study aims to explore the mechanism of the relationships between financial and non-financial outcomes and gender equality through a case study of a Japanese bank that has consistently pursued gender equality.

Design/methodology/approach

A single case study was adopted to explore the outcomes of promoting gender equality. Primary data were collected from 12 semi-structured interviews. Data were analysed by rereading and coding the interview responses coded to generate themes.

Findings

Through governance reform in Company A, women have been placed in top management positions and the number of female managers has increased, allowing frontline intentions to be reflected in decision-making. The increased number of female managers has led to a decrease in female turnover, men taking parental leave, improved training of female managers and the recruitment of excellent new graduates. The appropriate allocation of jobs to female managers and employees also meets customer needs and has led to increased sales. Finally, involvement of female employees in product development in male-dominated workplaces brings women’s experiences and perspectives to product development, resulting in the development of products that are favoured by customers.

Originality/value

This study determined the mechanism behind the relationships between financial and non-financial outcomes and gender equality, based on agency, upper echelons, resource dependence, institutional and social role theories. It also contributes to gender equality research methodology by providing compelling qualitative stories of gender equality outcomes to increase a company’s commitment to promoting gender equality.

Abstract

Parents ‘matter’ to schools for their child’s education and parents ‘matter’ in relation to their child’s wellbeing. Indeed, in his synthesis of over 800 studies, Hattie (2008) equated the benefits of parental engagement with schools as being equivalent to adding two or three further years to their education. The aim of this chapter, therefore, is to look at parents in relation to wellbeing through positive education and, as part of this, the concept of positive psychology parenting too. Drawing on scientific research, the benefits of positive psychology to parents and families, alongside some of the ‘why’ and ‘how’ parents can better engage with schools, will be presented. A Positive Psychology in Practice case study of Bounce Back, a freely available, online introduction to positive psychology designed to give parents and carers an introduction to several different concepts, approaches, and hands-on techniques, based on the principles of positive psychology, will also be provided. This case study will also present Bounce Back as an intervention, giving parents and carers practical advice on how best to use this online resource, as well as information on how to implement some of the wider ideas from positive education at home to help them better understand, and intervene in, their own and their family’s wellbeing.

Abstract

Purpose

The purpose of this study is to investigate the impact of rapid internationalization by emerging-market multinational enterprises (EMNEs) on their innovation performance. It also seeks to identify any potential moderating factors that could influence this relationship.

Design/methodology/approach

By analyzing data from listed Chinese MNEs from 2012 to 2022, this study applies a negative binomial regression model to test the research hypotheses.

Findings

This study uncovers an inverted U-shaped relationship between the internationalization speed of EMNEs and their innovation performance. It also suggests that strong absorptive, learning and managerial capacities could play positive moderating roles in the effect of internationalization speed on EMNEs’ innovation performance.

Originality/value

This study highlights rapid global expansion, promoting new knowledge acquisition for EMNEs. However, due to time-compression dilemmas with limited EMNE firm-specific advantages, overly accelerated internationalization hinders learning effectiveness. Additionally, this study reveals the critical importance of three firm-specific capacities in EMNEs – absorptive, learning and managerial capacities – in efficiently assimilating newly acquired knowledge from foreign markets and enhancing their innovation performance through rapid internationalization.

Abstract

Purpose

This paper aims to uncover patterns of Mexican craft beer consumers and guide companies’ decisions in the creation of new products, marketing strategies, advertising and promotion to increase craft beer sales and contribute to faster growth.

Design/methodology/approach

This is a conjoint analysis with a selection of attributes for new or renewed products, marginal disposition to pay for particular characteristics through brand-specific choice-based design, and market simulation.

Findings

This paper clearly demonstrates consumers’ preferences and willingness to pay in Mexico, with a cutting-edge market research technique combining the prioritization of preferred craft beer characteristics, and the price consumers are willing to pay for such product characteristics.

Research limitations/implications

The study's sample size of 501 responses is relatively small compared to the total number of craft beer consumers in Mexico. To enhance the validity and reliability of the findings, future studies should aim to obtain larger samples and compare their results with those of this study.

Practical implications

This study has important implications for craft beer producers, allowing them to develop targeted craft beers with appealing attributes for Mexican consumers, such as color, aroma intensity, alcohol degree intensity, bitterness, foam level and price.

Social implications

This study's market forecasting simulation technique is based on assumptions of consumer behavior and market dynamics. Although relevant variables were considered, unanticipated external factors or market changes could impact the forecasts' accuracy. This will allow for a more comprehensive understanding of craft beer consumer preferences in different markets and enhance the reliability of forecasting techniques.

Originality/value

This paper informs craft beer producers by providing valuable knowledge on customers’ preferences and willingness to pay to enhance craft beer companies’ product development processes.

Abstract

Purpose

Using social network theory (SNT), this study empirically examines the impact of digital supply chain announcements disclosing corporate social responsibility (CSR) information on stock market value.

Design/methodology/approach

Based on 172 digital supply chain announcements disclosing CSR information from Chinese A-share listed companies, this study uses event study method to test the hypotheses.

Findings

First, digital supply chain announcements disclosing CSR information generate positive and significant market reactions, which is timely. Second, strategic CSR and value-based CSR disclosed in digital supply chain announcements have a more positive impact on stock market, however there is no significant difference when the CSR orientation is either towards internal or external stakeholders. Third, in terms of digital supply chain network characteristics, announcements reflecting higher relationship embeddedness and higher digital breadth and depth lead to more positive increases of stock value.

Originality/value

First, the authors consider the value of CSR information in digital supply chain announcements, using an event study approach to fill the gap in the related area. This study is the first examination of the joint impact of digital supply chain and CSR on market reactions. Second, compared to the previous studies on the single dimension of digital supply chain technology application, the authors innovatively consider supply chain network relationship and network structure based on social network theory and integrate several factors that may affect the market reaction. This study improves the understanding of the mechanism between digital supply chain announcements disclosing CSR information and stock market, and informs future research.

Abstract

Purpose

In recent decades, emerging market multinational enterprises (EMNEs) have predominantly adopted a big step internationalization strategy to expand their business overseas. This study aims to examine the effect of big step internationalization on the speed of subsequent foreign direct investment (FDI) expansion for EMNEs. The authors also investigate the potential boundary conditions.

Design/methodology/approach

The authors use the random effects generalized least squares (GLS) regression following a hierarchical approach to analyze the panel data set conducted by a sample of publicly listed Chinese firms from 2001 to 2012.

Findings

The findings indicate that implementing big step internationalization in the initial stages accelerates the speed of subsequent FDI expansion. Notably, the authors find that this effect is more pronounced for firms that opt for acquisitions as the entry mode in their first big step internationalization and possess a board of directors with strong political connections to their home country’s government. In contrast, the board of director’s international experience negatively moderates this effect.

Practical implications

This study provides insights into our scholarly and practical understanding of EMNEs’ big step internationalization and subsequent FDI expansion speed, which offers important implications for firms’ decision-makers and policymakers.

Originality/value

This study extends the internationalization theory, broadens the international business literature on the consequences of big step internationalization and deepens the theoretical and practical understanding of foreign expansion strategies in EMNEs.

Abstract

Purpose

This study investigates the barriers and drivers of using green methods and technologies (GMTs) in supportive educational buildings (SEBs) in South Africa, and assesses their impact on the circular economy (CE) in achieving net-zero carbon goals. While there has been extensive literature on green building technologies, there is limited research on the barriers and drivers of using GMT in SEBs, as well as their impact on the circular economy (CE) in achieving net-zero carbon goals.

Design/methodology/approach

This study adopts an interpretivist approach with an ontological basis, using an overarching case study of a SEB at the University of Cape Town (UCT). Semistructured interviews were conducted with executive UCT management, and a field survey of a UCT supportive education building was performed.

Findings

At UCT, multiple GMTs have been installed across various buildings to enhance monitoring and management of water and energy consumption. Moreover, initiatives to positively influence student behavior, such as water and energy-saving campaigns around UCT premises, have been introduced. The findings further indicate that UCT has recently emphasized the implementation of GMTs, resulting in improved resource efficiency, CE practices and progress toward achieving net-zero carbon targets for supportive education buildings and the university as a whole.

Originality/value

This research highlights the positive impact of GMTs on a SEB’s CE and net-zero carbon operations. As a result, facility managers should consider incorporating GMTs when planning the development or refurbishment of SEBs.

Abstract

Purpose

The PICCH research project contributes to opening a dialogue between cultural heritage archives and users. Hence, the users are identified and their information needs, the search strategies they apply and the search challenges they experience are uncovered.

Design/methodology/approach

A combination of questionnaires and interviews is used for collection of data. Questionnaire data were collected from users of three different audiovisual archives. Semi-structured interviews were conducted with two user groups: (1) scholars searching information for research projects and (2) archivists who perform their own scholarly work and search information on behalf of others.

Findings

The questionnaire results show that the archive users mainly have an academic background. Hence, scholars and archivists constitute the target group for in-depth interviews. The interviews reveal that their information needs are multi-faceted and match the information need typology by Ingwersen. The scholars mainly apply collection-specific search strategies but have in common primarily doing keyword searching, which they typically plan in advance. The archivists do less planning owing to their knowledge of the collections. All interviewees demonstrate domain knowledge, archival intelligence and artefactual literacy in their use and mastering of the archives. The search challenges they experience can be characterised as search system complexity challenges, material challenges and metadata challenges.

Originality/value

The paper provides a rare insight into the complexity of the search situation of cultural heritage archives, and the users’ multi-facetted information needs and hence contributes to the dialogue between the archives and the users.

Abstract

Purpose

Physical activity (PA) has been widely studied for its individual and societal benefits, but research on how organisations can effectively promote workplace physical activity (WPA) programmes is lacking. This article aims to examine the organisational-level benefits and value drivers of corporate PA programmes whilst also exploring the factors that motivate employees to participate in these programmes.

Design/methodology/approach

The authors used the self-determination theory (SDT) and the Hungarian Sport Motivation Scale (H-SMS) – which was modified and validated from the original English SMS scale, which is one of the six most highly cited motivation questionnaires in sports – to assess employees' motivation towards sports. In conjunction, in-depth interviews with company representatives were conducted to create a mind map outlining the impacts and advantages of WPA programmes. The study involved interviews with 13 managers in Hungary and a survey completed by 728 employees.

Findings

The findings of the authors' study indicate that WPA programmes had positive effects on employee engagement, turnover reduction and absenteeism. However, the authors' results also revealed that employee motivation to participate in these programmes was primarily driven by external factors, such as identified and introjected regulators, indicating a low level of intrinsic motivation for sports in the workplace. It is important to classify employees based on their motivation and behaviour to design and promote effective PA programmes in the workplace and to increase participation rates.

Originality/value

The authors' findings indicate the importance of aligning WPA programme promotion with employee motivation. This can encourage organisations to initiate their programmes, address participation challenges and strive for higher engagement rates. Further research on employee motivation can support the development of more effective communication strategies for companies in this context.
