Abstract

Purpose

The “Internet of Things (IoT)” is a platform for involving smart devices via the Internet at a worldwide scale. It supports the “supply chain (SC)” and “information and communication technology (ICT)” infrastructure to be well integrated into an organization and externally with customers and suppliers. The “sustainable supply chain (SSC)” is currently unavoidable if a company seeks to satisfy the aggressive change in its customers' requirements. Numerous studies have confirmed that manufacturing firms have to accelerate the shift of their focus toward sustainability and the implementation of novel technologies, such as IoT, to accomplish their organizational goals most effectively. Although the literature consists of many theoretical approaches to IoT and numerous studies that have extremely concentrated upon the IoT technology and its potential applications, it lacks research with a focus on the challenges that arise when applying IoT to the “sustainable supply chain management (SSCM)”.

Design/methodology/approach

The present study proposes an integrated framework using the “Criteria Importance Through Intercriteria Correlation (CRITIC)” and “VlseKriterijumska optimizcija I kaompromisno resenje in Serbian (VIKOR)” models and employs to evaluate the IoT challenges to implement the SSCM. For estimating the criteria weights, the CRITIC tool is utilized. The organization's prioritization is obtained by the VIKOR procedure, which delivers simple mathematical procedures with precise and consistent outcomes.

Findings

To exhibit the practicality of the introduced model, a case study is taken to evaluate the IoT challenges to implement the SSCM within the “q-Rung Orthopair Fuzzy Sets (q-ROFSs)” environment. Moreover, the authors exhibit a sensitivity investigation over given parameter values, examining the stability of developed approach. Finally, the authors draw attention to a comparison between developed q-ROF-CRITIC-VIKOR decision-making approach with an existing q-ROF-TOPSIS method to show its superiority and potency.

Originality/value

The outcome of the study lies in observing the top benefits of individual businesses, and their entire SSCs can be found by implementing IoT. This paper investigates the most important challenges that individual firms and entire SSCs might while applying IoT. It provides a deep insight regarding the effects of IoT upon SSCM and the issues every firm need to contemplate when it is to apply IoT solutions.

Abstract

Purpose

The purpose of this paper is to build a mobile visual search service system for the protection of Dunhuang cultural heritage in the smart library. A novel mobile visual search model for Dunhuang murals is proposed to help users acquire rich knowledge and services conveniently.

Design/methodology/approach

First, local and global features of images are extracted, and the visual dictionary is generated by the k-means clustering. Second, the mobile visual search model based on the bag-of-words (BOW) and multiple semantic associations is constructed. Third, the mobile visual search service system of the smart library is designed in the cloud environment. Furthermore, Dunhuang mural images are collected to verify this model.

Findings

The findings reveal that the BOW_SIFT_HSV_MSA model has better search performance for Dunhuang mural images when the scale-invariant feature transform (SIFT) and the hue, saturation and value (HSV) are used to extract local and global features of the images. Compared with different methods, this model is the most effective way to search images with the semantic association in the topic, time and space dimensions.

Research limitations/implications

Dunhuang mural image set is a part of the vast resources stored in the smart library, and the fine-grained semantic labels could be applied to meet diverse search needs.

Originality/value

The mobile visual search service system is constructed to provide users with Dunhuang cultural services in the smart library. A novel mobile visual search model based on BOW and multiple semantic associations is proposed. This study can also provide references for the protection and utilization of other cultural heritages.

Abstract

Purpose

Aspect category-based sentiment analysis (ACSA) has been widely used in consumer preference mining and marketing strategy formulation. However, existing studies ignore the variability in features and the intrinsic correlation among diverse aspect categories in ACSA tasks. To address these problems, this paper aims to propose a novel integrated framework.

Design/methodology/approach

The integrated framework consists of three modules: text feature extraction and fusion, adaptive feature selection and category-aware decision fusion. First, text features from global and local views are extracted and fused to comprehensively capture the potential information in the different dimensions of the review text. Then, an adaptive feature selection strategy is devised for each aspect category to determine the optimal feature set. Finally, considering the intrinsic associations between aspect categories, a category-aware decision fusion strategy is constructed to enhance the performance of ACSA tasks.

Findings

Comparative experimental results demonstrate that the integrated framework can effectively detect aspect categories and their corresponding sentiment polarities from review texts, achieving a macroaveraged F1 score (Fmacro) of 72.38% and a weighted F1 score (F1) of 79.39%, with absolute gains of 2.93% to 27.36% and 4.35% to 20.36%, respectively, compared to the baselines.

Originality/value

This framework can simultaneously detect aspect categories and corresponding sentiment polarities from review texts, thereby assisting e-commerce enterprises in gaining insights into consumer preferences, prioritizing product improvements, and adjusting marketing strategies.

Abstract

Purpose

High-tech enterprises, as the national innovation powerhouses, have garnered considerable interest, particularly regarding their technological innovation capabilities. Nevertheless, prevalent research tends to spotlight the impact of individual factors on innovative behavior, with only a fraction adopting a comprehensive viewpoint, scrutinizing the causal amalgamations of precursor conditions influencing the overall innovation proficiency of high-tech enterprises.

Design/methodology/approach

This paper employs a hybrid approach integrating necessary condition analysis (NCA) and fuzzy-set qualitative comparative analysis (fsQCA) to examine the combinatorial effects of antecedent factors on high-tech enterprises' innovation output. Our analysis draws upon data from 46 listed Chinese high-tech enterprises. To promote technological innovation within high-tech enterprises, we introduce a novel perspective that emphasizes technological innovation networks, grounded in a network agents-structure-environment framework. These antecedents are government subsidy, tax benefits, customer concentration, purchase concentration rate, market-oriented index and innovation environment.

Findings

The findings delineate four configurational pathways leading to high innovative output and three pathways resulting in low production.

Originality/value

This study thereby enriches the body of knowledge around technological innovation and provides actionable policy recommendations.

Abstract

Purpose

This paper aims to study the application of reinforcement learning (RL) in the control of an output-constrained flapping-wing micro aerial vehicle (FWMAV) with system uncertainty.

Design/methodology/approach

A six-degrees-of-freedom hummingbird model is used without consideration of the inertial effects of the wings. A RL algorithm based on actor–critic framework is applied, which consists of an actor network with unknown policy gradient and a critic network with unknown value function. Considering the good performance of neural network (NN) in fitting nonlinearity and its optimum characteristics, an actor–critic NN optimization algorithm is designed, in which the actor and critic NNs are used to generate a policy and approximate the cost functions, respectively. In addition, to ensure the safe and stable flight of the FWMAV, a barrier Lyapunov function is used to make the flight states constrained in predefined regions. Based on the Lyapunov stability theory, the stability of the system is analyzed, and finally, the feasibility of RL in the control of a FWMAV is verified through simulation.

Findings

The proposed RL control scheme works well in ensuring the trajectory tracking of the FWMAV in the presence of output constraint and system uncertainty.

Originality/value

A novel RL algorithm based on actor–critic framework is applied to the control of a FWMAV with system uncertainty. For the stable and safe flight of the FWMAV, the output constraint problem is considered and solved by barrier Lyapunov function-based control.

Abstract

Purpose

The governance of information technology outsourcing (ITO) has been identified as an essential determinant for ITO success. Prior studies have shed light on effective governance structures in different organizational contexts. This study aims to advance this prior knowledge by exploring how interpersonal networks, as an important aspect of such context, reflect and influence ITO governance.

Design/methodology/approach

A single case study was conducted from a vendor’s perspective in an ITO dyad. Social network analysis was leveraged to reveal the interpersonal networks, with whole-network analysis on 24 team members in an ITO vendor company. In addition, open-ended interviews with six selected team members were utilized to identify the perceived governance structure.

Findings

The findings of this study suggest certain features of interpersonal networks, i.e. network density and cross-network comparison, can reflect governance structure in multiple aspects. Meanwhile, the authors also argue that interpersonal networks can influence the form of governance structure.

Research limitations/implications

As a single case study, the context of the research site cannot be ignored in the inference of findings. To increase the confidence for further generalization, future empirical studies are needed especially in contrasting sites, such as ITO relations based on network governance.

Originality/value

This study associates intra-organizational characteristics of the vendor to the inter-organizational governance structure of the ITO relationship. It also provides an innovative methodology for both researchers and practitioners to assess ITO governance structure.

Abstract

Purpose

This study aims to empirically investigate and extend the diversity-meritocracy paradox outlined by Konrad et al. (2021) using skilled immigrants in Canada as a case study. Despite their significance in knowledge-based economies, immigrant voices are often marginalized in diversity, equity and inclusion (DEI) literature and management research. By focusing on skilled immigrants, who embody both diversity and meritocratic principles, this research addresses this gap. Through semi-structured interviews, we examine whether diversity and meritocracy are perceived as contradictory or complementary for skilled immigrants. Our findings not only contribute to theoretical understanding but also offer practical insights into the complexities of diversity and meritocracy in contemporary organizations.

Design/methodology/approach

This study utilizes qualitative, semi-structured, interviews and focus groups to gather data from both employers and skilled immigrants. Thematic analysis, guided by Braun and Clarke (2006), is employed to analyze the data. Participants include skilled immigrants and human resource (HR) professionals/managers. Data are collected through interviews and focus groups conducted between December 2018 and February 2020 in person and via video-conferencing.

Findings

This study unveils a discrepancy in perceptions between employers and skilled immigrants on DEI in Canada’s labor market. While employers prioritize meritocracy, emphasizing Canadian qualifications and experience, immigrants feel undervalued, encountering barriers due to cultural differences. Employers focus on past work experience over credentials, using behavioral interviews and proficiency tests for assessment. However, immigrants often perceive the selection process as opaque, and encounter explicit preferences for Canadian education and experience, which they view as discriminatory. Challenges in onboarding, training and workplace culture further exacerbate their experiences. These findings highlight the nuanced dynamics between meritocracy and diversity, underscoring the need for systemic change.

Originality/value

Despite employers’ claims of valuing diversity, our findings reveal a preference for “Canadian-ness” over immigrants' international expertise, perpetuating systemic barriers. Employers prioritize meritocracy but often conflate it with cultural conformity, hindering immigrant integration. Our analysis underscores the disconnection between organizational rhetoric and practices, urging a reconceptualization of diversity and inclusion policies. To foster truly inclusive workplaces, both surface-level and deep-level diversity must be considered. Policy interventions and enhanced intercultural competence are essential for leveraging the talents of skilled immigrants and promoting equitable employment practices.
