Abstract

Purpose

This paper aims to facilitate reliable online diagnosis of early faults in the stator winding inter-turn short circuits of induction motors (IMs) under various operating conditions.

Design/methodology/approach

A novel fault characteristic component, the characteristic current amplitude, is proposed for the fault. Defined as the product of short-circuit coefficient and short-circuit current, the characteristic current is derived from the positive and negative-sequence components of the stator-side current and voltage.

Findings

Simulation models of the IMs pre- and postfault, along with an experimental platform for the motor’s inter-turn short circuit, were established. The characteristic current amplitude proves more robust against voltage unbalance and load variations, which offers enhanced reliability and sensitivity for early fault diagnosis of inter-turn short circuit in IMs stator windings.

Originality/value

A novel feature is proposed. Compared with negative-sequence current, which is considered as a traditional fault feature, the characteristic current amplitude exhibits a greater robustness against the imbalanced conditions, which simultaneously possesses the attributes of both reliability and expeditiousness in fault detection.

Abstract

Purpose

This study aims to explore the traditional plant dyeing of Xinjiang Atlas silk fabrics, providing references for the comprehensive utilization of plant dyes in intangible cultural heritage.

Design/methodology/approach

The focus of this study is on dyeing experiments of Atlas silk fabrics using safflower extracts, constrained by regional resources. Safflower dry flowers grown in Xinjiang were selected, rinsed with pure water and rubbed. Yellow pigments were removed by adding edible white vinegar. Red pigments from safflower were extracted using an alkaline solution prepared with Populus euphratica ash, a special product of Xinjiang. The extraction rate was analyzed under varying material-to-liquor ratios, pH values, times and temperatures. Direct dyeing process experiments were conducted to obtain different colorimetric L, a, b and K/S values for comparison. Samples with good color development were selected to test the impact of dyeing immersions on color development, and their color fastness, UV protection and antibacterial effects were verified.

Findings

The dyeing experiments on silk fabrics confirmed their UV protection capabilities and antibacterial properties, demonstrating effectiveness against E. coli and Staphylococcus aureus. As a major producer of safflower, Xinjiang underscores the significance of safflower as an essential plant dyes on the Silk Road. This study reveals its market potential and suitability for use in the plant dyeing process of Atlas silk, producing vibrant red and pink colors.

Originality/value

The experiments indicated that after removing yellow pigments, the highest extraction rate of red pigment from safflower was achieved at a pH value of 10–11, a temperature of 30°C and an extraction time of 40 min. The best bright red color effect with strong color fastness was obtained with a material-to-liquor ratio of 1:20, a temperature of 40°C and three immersions. The best light pink color effect with strong color fastness was a material-to-liquor ratio of 1:80, a temperature of 30°C and two immersions.

Abstract

Purpose

Previous studies have rarely integrated the financing modes of a capital-constrained manufacturer with the choices of online sales strategies. To address this gap, the authors study how a manufacturer selects optimal financing modes under different sales strategies in three dual-channel supply chains.

Design/methodology/approach

This paper considers three sales strategies, namely, combining a traditional retailer channel with one of the direct selling, reselling and agency selling channels, and two common financing modes, namely, bank financing and retailer financing. The authors obtain equilibrium outcomes of the manufacturer and traditional retailer and then provide the conditions for them to select optimal financing modes under three sales strategies.

Findings

The results indicate that the manufacturer’s financing decisions rely on the initial capital and interest rates, and the manufacturer selects retailer financing only if the initial capital is relatively larger. In terms of financing mode options, the retailer financing mode is more beneficial for the manufacturer under the three sales strategies. From the perspective of sales strategies, the direct selling model is more beneficial. In addition, the higher the consumer acceptance of the online channel, the more profits the manufacturer obtains.

Practical implications

This paper provides suggestions on how the capital-constrained manufacturer chooses financing modes and sales strategies.

Originality/value

This paper integrates the financing mode and different sales strategies to investigate the manufacturer’s optimal operational decisions. These sales strategies allow us to investigate the manufacturer’s optimal financing modes in the presence of both different financing modes and sales strategies.

Abstract

Purpose

This study empirically investigates how source factors of the streamers affect swift guanxi between the streamers and consumers and their subsequent impacts on consumers’ purchase intentions in live stream e-commerce in China.

Design/methodology/approach

Drawing on source credibility theory (Weiss, 1974) and source attractiveness theory (McGuire, 1985), our study hypothesizes that the expertise, similarity, familiarity and likability of streamers are such source factors. For this empirical investigation, the study conducted online surveys with 428 adult Chinese consumers with previous purchasing experience on live-streaming platforms.

Findings

The study found positive effects with source expertise, familiarity and likeability on swift guanxi and purchase intentions; however, we found no such positive effect for source similarity. Overall, our findings suggest that source factors can have significant effects on swift guanxi and that swift guanxi constructed with source factors can have subsequent effects on purchase intentions.

Originality/value

This study conceptualizes and empirically tests the role of streamer credibility and attractiveness in live stream e-commerce.

Abstract

Purpose

Entrepreneurship of universities has a critical role due to its important effects. However, there is a significant gap in the literature regarding the methodology for evaluating university entrepreneurship. Evaluating university entrepreneurship provides valuable information to policymakers and governments. This research presents an evaluation methodology for assessing university entrepreneurship using a hybrid multi-criteria decision-making (MCDM) approach.

Design/methodology/approach

For this purpose, entrepreneurship data of 50 universities from Türkiye were used. The evaluation framework consists of 4 main criteria and 23 sub-criteria. The importance level was determined by weighting the main criterion and sub-criteria with the subjective Best-Worst Method (BWM) based on expert opinions and the objective CRiteria Importance Through Intercriteria Correlation (CRITIC) method. The importance levels were determined by weighting the main and sub-criteria using the subjective BWM based on expert opinions and the objective CRITIC method. The final rankings were obtained by integrating the different ranking values obtained with the Borda function.

Findings

Findings revealed that the most important main criterion in the entrepreneurship of universities is economic and social contribution activities, and the most important sub-criterion is international patents. The proposed method ranked all universities according to entrepreneurship. Sensitivity and validation analyses proved that the method is robust, stable and consistent.

Practical implications

This study also provides a new perspective to policymakers and decision-makers in evaluating university entrepreneurship.

Originality/value

This study, which uses a hybrid approach of MCDM methods to evaluate the entrepreneurship of universities, can be adapted to different national and regional higher education systems, and this study provides guidance to researchers in this regard.

Abstract

Purpose

This study aims to provide a new perspective on the impact of mortality threats on consumer behavior through the lens of brand anthropomorphism. It examines the mediating effects of control and connectedness motives and the moderating effects of brand roles on the relationship between mediators and brand attitudes.

Design/methodology/approach

A preliminary study explored the relationship between pandemic-induced mortality threats and attitudes toward anthropomorphized brands. Study 1 investigated the underlying mechanism, and Study 2 examined the moderating effects of servant or partner roles. Study 3 confirmed the mortality threat effect on anthropomorphic brand attitudes in the absence of the pandemic.

Findings

The study revealed that mortality threats enhanced the desire for control and connectedness, which strengthened attitudes toward anthropomorphized brands. The results also indicated matching effects between the motivations for anthropomorphism and brand roles.

Originality/value

This research offers novel insights into the effects of pandemic-induced mortality threats and mortality threats in non-pandemic contexts on anthropomorphic motives. It highlights the influence of these psychological needs on consumer responses to brand roles and provides insights for brand management during a crisis.

Abstract

Purpose

In recent years, augmented reality (AR) emerged as a notable technology within the fashion industry, enhancing consumers’ shopping experience by offering virtual try-on (VTO). To comprehensively understand female apparel consumers’ adoption intentions of this novel shopping tool, this study expanded the Technology Acceptance Model by incorporating constructs from Innovation Diffusion Theory and two psychological factors – fit confidence (FC) and body esteem (BE).

Design/methodology/approach

This study used a scenario-based design where participants imagined dress shopping, watched a video of a woman using an AR-based VTO app and then completed a survey. The sample included a total of 388 U.S. female participants.

Findings

The findings demonstrated the explanatory power of the research model and highlighted important factors affecting adoption decisions. Among the five innovative dimensions, relative advantage, complexity and trialability significantly impacted perceived ease of use (PEOU) and/or perceived usefulness (PU). PEOU, PU, FC and BE all significantly affected attitude and purchase intention, with attitude partially mediating the effects on intention.

Practical implications

Findings highlight that retailers can enhance AR-based VTO adoption by promoting its relative advantages, such as convenience and personalization, and by offering free trials or demos to increase the PEOU. Furthermore, designing AR-VTO features with inclusivity and body positivity can address consumer concerns about fit and body image, improving engagement and satisfaction. These insights provide actionable strategies for technology developers and retailers aiming to create consumer-centric shopping experiences.

Originality/value

This study examined both technological and psychological antecedents, providing researchers and marketers with a comprehensive understanding of fashion consumers’ shopping experiences using AR-based VTO.

Abstract

Purpose

Plant-based meat analogues (PBMAs) hold significant promise as a sustainable solution to meet future protein demands, replicating the taste and nutritional value of meat. However, the present reliance on extrusion technology in PBMA production limits the exploration of more accessible and affordable methods. The current investigation aims to meet the market demand for a scalable and cost-effective processing approach by exploring saturated steam-assisted technology that could broaden the production volume of PBMAs, thereby supplementing protein security and planet sustainability.

Design/methodology/approach

A one-factor-at-a-time (OFAT) approach is employed to evaluate the effect of ingredients and process conditions on the governing quality attributes (texture, colour and sensory).

Findings

Among the ingredients, monosodium glutamate (MSG) and nutritional yeast (NY) significantly enhanced the hardness and chewiness of saturated steam-assisted plant-based meat analogues (ssPBMAs) followed by potato protein isolate (PPI), defatted soy flour (DSF) and salt. The addition of PPI and DSF led to a decrease in lightness (L* value) and an increase in the browning index (BI). Sensory evaluations revealed that higher concentrations of DSF imparted a noticeable beany flavour (>20%), whereas PPI (30%) improved the overall sensory appeal. Increased levels of NY (10%) and MSG (5%) enhanced the umami flavour, enhancing consumer preference. Higher thermal exposure time (TTi) (45 min) and temperature (TTe) (120 °C) during processing resulted in softer products with reduced L* values. These findings establish a foundation for selecting and optimizing the ingredients and processing parameters in ssPBMA production.

Originality/value

The novelty of the current study includes process behaviour of selected ingredients such as PPI, NY, MSG, DSF, salt and adopted process conditions, namely, dough processing time (DPT), protein network development time (PNDT), TTi and TTe on the quality of ssPBMAs.

Abstract

Purpose

Fire safety is a pivotal requirement in building codes. Prescribed design criteria have been the norm to achieve it, which imposes limitations on engineers, including the inability to accommodate new solutions/materials. The shift towards performance-based design offers the potential to address shortcomings of the prescribed design. However, this shift also significantly increases the workload on structural engineers without a corresponding increase in their engineering fees. Simplified design tools are needed to assist engineers in this transition.

Design/methodology/approach

The paper is divided into sections investigating equivalent standard fire duration, thermal deformations, flexural behaviour and shear capacity of flat slabs when exposed to fire. The first section conducts a parametric study correlating equivalent and realistic fire durations using the average internal temperature profile (AITP) method, resulting in statistical equations estimating equivalent fire duration. The second section evaluates thermal deformations and flexural behaviour through a parametric study considering various parameters. This section results in statistical equations estimating thermal deformations and flexural behaviour of flat slab sections during fire exposure. The final section focuses on shear capacity, developing simplified heat transfer formulas and statistical equations predicting compression zone depth reduction. The section presents methodologies predicting flat slab sections' one-way and two-way shear capacities during fire exposure.

Findings

Structural engineers can use the proposed methods for daily design work without applying complex heat transfer calculations. When the equivalent standard fire duration is utilized, a flat slab’s thermal deformations, flexural behaviour and shear capacity under an actual fire condition can be calculated. As such, the methods would be highly beneficial in assessing the structural integrity of a building during an active fire incident.

Originality/value

The paper provides engineers with the tools required to evaluate the safety of flat slab sections during fire exposure. The methodologies presented in the paper enable engineers to use performance-based design for slab sections by (1) converting any real fire scenario to a standard fire with an equivalent duration, (2) assessing their thermal behaviour, (3) evaluating their flexural behaviour and (4) evaluating their flexural and shear capacities. The paper concludes with a case study example demonstrating the detailed application of the developed methods.

Abstract

Purpose

Conspicuously absent from the branding literature is research on the brand-to-brand (Br2Br) interface enabled by social media. The author proposes how networked brands-as-actors integrate their resources as Br2Br interactions that co-create consumer–brand value. As a secondary contribution, the author provides an empirical baseline exploration of the value co-creating impact of Br2Br interactions on consumer–brand evaluations and social media engagement.

Design/methodology/approach

Three streams of research aid in conceptualizing the value co-creating process of Br2Br interactions. A follow-up exploratory study uses a controlled Br2Br interaction stimulus in a 2 × 2 × 2 between-subjects design, where brand familiarity and product category complementarity are manipulated, and interaction spillover effects are analyzed using structural equation modeling.

Findings

The author finds Br2Br interactions positively affect consumer–brand evaluations and social media engagement likelihood. Spillover effects of these interactions are symmetric for consumer–brand evaluations for both brands. However, brand familiarity moderates the effects of Br2Br interactions on consumer–brand evaluations.

Originality

The author lays the groundwork for future research on the complexities of Br2Br interactions – including brand personality conflict, interaction duration and paratextual language – and the boundary conditions for Br2Br and brand-to-consumer relationships.
