Abstract

This paper presents the calculation of pulsating losses in the air‐gap at laminated stator and rotor pole surface of the synchronous reluctance motor (SRM). The calculation is based on change of magnetic flux density in the air‐gap due to the permeance variation on both stator and rotor inner surfaces. These changes are calculated using finite element method. The equation for calculation of the pulsating losses is carried out using reduced Helmholtz's differential equation and the 1st Maxwell equation. Finally, the values measured and calculated are compared to each other.

Abstract

Purpose

Although a construction logistics solution is necessary for dealing with the demands in many large urban development projects, there is a lack of research on governance mechanisms for construction logistics solutions. Therefore, the purpose of this paper is to analyse the initiation and utilisation of a construction logistics centre (CLC) from different stakeholders’ perspectives to suggest governance mechanisms for strategic, tactical and operational levels and to develop guidelines for implementing these governance mechanisms.

Design/methodology/approach

A single case research design was used. Data were collected through interviews, site visits, observations and documentation from four stakeholder groups.

Findings

There is potential for utilising CLCs in development projects, with positive effects such as consolidation effects and enhanced planning. What is evident, however, is that the design and implementation of the CLCs must be based on a comprehensive stakeholder analysis, as there are conflicting goals between stakeholders. Governance mechanisms, including flexibility in the main contractors’ working construction process, as well as clearly stated roles, responsibilities and communication must be developed to enhance this potential.

Research limitations/implications

The conflicting goals of CLCs are identified and discussed, and the results show the need for further multi-stakeholder analysis of construction logistics solutions.

Practical implications

The experiences from the studied case are developed into practical guidelines to be used in the design of construction logistics solutions in development projects.

Originality/value

This study contributes by taking a multi-stakeholder perspective on CLCs and providing guidelines to be used in the design of construction logistics solutions in development projects.

Abstract

Purpose

The purpose of this study is to identify and validate the key consumer-related factors influencing consumer attitude toward electric vehicles (EVs) and intention to purchase EVs. The role of consumer attitude in mediating consumer-related factors and intention to buy is also explored in this study. Consumer-related factors considered in this study include environmental orientation (EO), new technology orientation (NTO), social orientation (SO) and perceived monetary benefits (PMB).

Design/methodology/approach

Data for the study were collected from individuals who do not own an EV in Chennai, Tamil Nadu, India. Data were collected from 388 respondents using Google Forms. Convenience sampling technique was used to identify the respondents. Both descriptive and inferential statistics techniques were used to analyze data collected.

Findings

The study identified EO, SO and PMB as antecedents of attitude (ATT) toward EV and NTO, SO and PMB as potential drivers of EV purchase intention (PI). In addition, the authors also observe that EO is fully mediated by ATT toward consumer PI, whereas ATT partially mediates the relationship between the independent variables SO and PMB and the dependent variable PI.

Practical implications

EVs are at the forefront of automotive innovation. Automobile industries producing EVs showcase a commitment to embracing cutting-edge technology, positioning their companies as forward-thinking and technologically advanced. Creating awareness about EV technology, dispelling myths about range anxiety and charging times should be done methodologically. The lower operating costs of EVs and the government policies that reduce the total cost of ownership can lead to faster market penetration. The widespread adoption of EVs can contribute to a nation’s economic growth by adding new businesses in the industry, infrastructure development and job creation.

Social implications

The reduced environmental impact of EVs, such as improved air quality and reduced greenhouse gas emissions, can lead to significant societal benefits in terms of better human health and mitigating the effects of climate change. Governments can leverage these benefits to achieve climate targets and improve public health.

Originality/value

Studies about EV diffusion and adoption in India are yet to gain momentum considering the slow penetration of EVs in the Indian automobile market. The Indian Government is enforcing policies and incentives to accelerate the adoption of EVs. However, without understanding the drivers of consumer EV adoption, it is difficult for policymakers to accelerate the growth of the EV market. The present study is one step toward understanding the same in its original sense.

Abstract

Purpose

The purpose of this study is to examine consumer attitude toward gamification in the context of over-the-top (OTT) media service. The particular focus of this paper is on game mechanics from the mechanics-dynamics-aesthetics framework and its effects on consumer attitude toward both gamification and OTT media service provider brand.

Design/methodology/approach

A 2 × 2 × 2 between-subjects factorial experiment to examine the three core elements of game mechanics – components, controls and courses on consumer attitude, which was operationalized in eight vignettes with a sample size of 296.

Findings

It was found that the three elements in game mechanics demonstrated a multiplicative effect. The different combinations of elements in game mechanics would result in eliciting different consumer attitudes toward gamification and brand. Despite one combination that attained a high positive consumer attitude toward gamification in OTT, that same combination was not effective in creating a high positive attitude toward the OTT provider brand. The findings demonstrate the need for OTT providers to be clear of their gamification objectives before selecting the combination of game mechanics.

Research limitations/implications

This study adds to the body of knowledge on consumer attitude toward gamification, especially in the OTT market where there is still literature is limited.

Practical implications

OTT providers should determine their objectives for using gamification and design the game mechanics according to the optimal combination of elements – components, controls and courses.

Originality/value

According to the author’s knowledge, this is the first paper to examine consumer attitude toward gamification and OTT provider based on game mechanics. It provides an understanding on the interaction of elements in game mechanics and shows that different element combinations can be used to meet different goals.
