This research aims to develop a blockchain smart contract–enabled framework to resolve power imbalance problems in construction payment.

Abstract

Purpose

This research aims to develop a blockchain smart contract–enabled framework to resolve power imbalance problems in construction payment.

Design/methodology/approach

This research adopts a design science research method to develop the blockchain smart contract–enabled framework. The authors then develop a prototype system. Finally, the authors evaluate its performance in solving power imbalance-induced payment problems.

Findings

The results show that the prototype system can resolve power imbalance problems in construction payment by allowing project participants to make transparent and decentralized decisions that are self-enforceable by blockchain smart contracts.

Research limitations/implications

This study provides theoretical explanations for how blockchain smart contracts can resolve power imbalances in construction payment; based on that, it proposes a novel blockchain smart contract–enabled method to rebalance the power of stakeholders in construction payment. Thus, it contributes to the body of knowledge on blockchain technology and construction payment.

Practical implications

This study moves beyond a conceptual framework and develops a practical blockchain smart contract system for resolving power imbalances in construction payment, strengthening construction project members' confidence in using blockchain technology.

Social implications

The proposed blockchain smart contract–enabled solution helps mitigate negative social impacts associated with late payment and non-payment. Furthermore, the research maximizes trust among participants in payment processes to inspire collaborative culture in the construction industry.

Originality/value

This paper introduces a novel blockchain smart contract integrated method, allowing project stakeholders to resolve power imbalance problems in construction payment through decentralized decision-making.

Abstract

Purpose

The purpose of this paper is to examine the nature of cyberbullying and corresponding strategies being used under the New United Arab Emirates (UAE) Cybercrimes Law.

Design/methodology/approach

The analysis begins with a review of the nature of cyberbullying, focusing primarily on key concepts, underlying risk factors, forms of cyberbullying and adverse effects. Background information about the nature of cyberbullying will then lay the foundation for the subsequent sections of the analysis, which will focus on preventive strategies and legislative measures. The second section of the analysis will entail a review of the legislative framework for cyberbullying in the UAE. The goal here is to examine how the UAE is responding to the emerging threat of cyberbullying in its jurisdiction. The next section will then shift gears to interventions and strategies being implemented at the global level. A global perspective is central to comparing practices in the UAE to international standards and regulations.

Findings

Findings from the analysis have shown that the UAE has the most robust and comprehensive cyberbullying laws internationally. Nonetheless, the New Cybercrimes Law is ambiguous, and it is not expressively specific to cyberbullying. The law does not have a clear definition of cyberbullying, as well as the scope of its application to specific cases involving students. A comparative analysis across jurisdictions has revealed that most countries neither have specific cyberbullying laws nor explicitly define the phenomenon in existing laws. Thus, cyberbullying is a gray area in the UAE national law, requiring a clear definition and scope of application. The courts will establish case law that will finally address the current definitional challenges and extend of applying the New Cybercrimes Law.

Originality/value

The analysis concludes with the application of international best standards and practices to the UAE context, focusing specifically on how to strengthen laws and procedures in the UAE.

Abstract

Purpose

This study aims to investigate the equity market reaction to sustainability disclosure measures derived from firms' inaugural sustainability reports following the implementation of mandatory sustainability reporting in Singapore.

Design/methodology/approach

This study explores the equity market reaction to first-time sustainability reports of mandatory adopters and compares the reactions between voluntary and mandatory adopters. To mitigate any imbalanced distribution effects, entropy balancing techniques are employed.

Findings

The author observes a significant equity market reaction when mandatory adopters adhere to a reporting framework and release sustainability reports as standalone documents. Additionally, the study indicates that government regulation amplifies the equity market reaction for companies that include a board statement within their sustainability reports and present them as standalone publications.

Research limitations/implications

The lack of quantitative information disclosed in the first-time sustainability reports may restrict the generalizability of the findings.

Practical implications

The findings provide valuable insights for organizations and managers to evaluate the market's response to sustainability disclosures and improve communication effectiveness with investors. Furthermore, the study has direct policy implications for global standard-setting organizations in sustainability reporting. The findings support the notion that investors value market-led and investor-focused sustainability disclosures.

Originality/value

The study contributes to the limited body of research that examines the capital market effects of mandatory sustainability disclosures. To the author’s knowledge, this is among a few studies to directly investigate the equity market reaction to mandatory sustainability disclosures at the firm level.

Abstract

Purpose

With the rapid growth of the domestic lending industry, assessing whether the borrower of each loan is at risk of default is a pressing issue for financial institutions. Although there are some models that can handle such problems well, there are still some shortcomings in some aspects. The purpose of this paper is to improve the accuracy of credit assessment models.

Design/methodology/approach

In this paper, three different stages are used to improve the classification performance of LSTM, so that financial institutions can more accurately identify borrowers at risk of default. The first approach is to use the K-Means-SMOTE algorithm to eliminate the imbalance within the class. In the second step, ResNet is used for feature extraction, and then two-layer LSTM is used for learning to strengthen the ability of neural networks to mine and utilize deep information. Finally, the model performance is improved by using the IDWPSO algorithm for optimization when debugging the neural network.

Findings

On two unbalanced datasets (category ratios of 700:1 and 3:1 respectively), the multi-stage improved model was compared with ten other models using accuracy, precision, specificity, recall, G-measure, F-measure and the nonparametric Wilcoxon test. It was demonstrated that the multi-stage improved model showed a more significant advantage in evaluating the imbalanced credit dataset.

Originality/value

In this paper, the parameters of the ResNet-LSTM hybrid neural network, which can fully mine and utilize the deep information, are tuned by an innovative intelligent optimization algorithm to strengthen the classification performance of the model.

Abstract

Purpose

Recommendation systems are a fundamental tool for hotels to adopt a differentiating competitive strategy. The main purpose of this work is to use machine learning techniques to treat imbalanced data sets, not applied until now in the tourism field. These techniques have allowed the authors to analyse the influence of imbalance data on hotel recommendation models and how this phenomenon affects client dissatisfaction.

Design/methodology/approach

An opinion survey was conducted among hotel customers of different categories in 120 different countries. A total of 135.102 surveys were collected over eleven quarters. A longitudinal design was conducted during this period. A binary logistic model was applied using the function generalized lineal model (GLM).

Findings

Through the analysis of a representative amount of data, the authors empirically demonstrate that the imbalance phenomenon is systematically present in hotel recommendation surveys. In addition, the authors show that the imbalance exists independently of the period in which the survey is done, which means that it is intrinsic to recommendation surveys on this topic. The authors demonstrate the improvement of recommendation systems highlighting the presence of imbalance data and consequences for marketing strategies.

Originality/value

The main contribution of the current work is to apply to the tourism sector the framework for imbalanced data, typically used in the machine learning, improving predictive models.

Abstract

Purpose

While prior research has established that traumatic brain injury (TBI) is a risk factor for violent offending, there is little understanding of mechanisms that may underpin this relationship. This is problematic, as a better understanding of these mechanisms could facilitate more effective targeting of treatment. This study aims to address these gaps in the extant literature by examining TBI as a predictor of violent offending and test for mediation effects through cognitive constructs of dual systems imbalance and hostility among a sample of justice-involved youth (JIY).

Design/methodology/approach

The Pathways to Desistance data were analyzed. The first three waves of this data set comprising the responses of 1,354 JIY were analyzed. Generalized structural equation modeling was used to test for direct and indirect effects of interest. A bootstrap resampling process was used to compute unbiased standard errors for determining the statistical significance of mediation effects.

Findings

Lifetime experience of TBI was associated with increased violent offending frequency at follow-up. Hostility significantly mediated this relationship, but dual systems imbalance did not. This indicated that programming focused on reducing hostility among JIY who have experienced TBI could aid in reducing violent recidivism rates.

Originality/value

To the best of the author’s knowledge, this study was the first to identify significant mediation of the relationship between TBI and violent offending through hostility.

Abstract

Purpose

Leveraging Emerson’s theory of power and motivated reasoning, this study aims to explore how the net power of an individual and actual, instead of perceived, vulnerability results in asymmetric trust and distrust development in a dyadic relationship.

Design/methodology/approach

Based on extant literature and gaps in the literature, this conceptual paper hypothesises and proposes trust formation based on power dynamics and vulnerability.

Findings

This research extends the knowledge base by exploring the role of actual vulnerability over perceived vulnerability in trust formation and distrust formation.

Research limitations/implications

The research propositions imply that the dyadic trust formation process is not rational, and trust itself is not symmetrical but asymmetrical. The net power possessed by one individual over the other drives trust. Net power balance determines the actual vulnerability of the focal individual, and then the individual, through motivated reasoning, trusts or distrusts another individual. Scholars, going forward, could explore how trust formation varies at group and firm levels.

Originality/value

Extant literature has not explored the role of power imbalance in determining actual (versus perceived) vulnerability that influences trust formation between parties. The conceptual paper fills this gap.

Abstract

Purpose

Cyberbullying is a globally pervasive problem and not novel in academia. Previous studies mainly focussed on the features, consequences and technological management of cyberbullying. However, most of the studies took cyberbullying examples in the West, and some issues still need to be addressed in the Chinese context. Thus, this study investigates how participants use cyberbullying words and why they use them in that particular way in China.

Design/methodology/approach

This study uses content analysis to summarise the typical features of cyberbullying words, revealing a positive relationship between cyberbullying words and sentimental expressions. This paper also uses the questionnaire (N = 705) to explore the prevalence of cyberbullying among Chinese Internet users and to compare the gender differences in the cognition of cyberbullying words and involvement in cyberbullying, in line with the social cognitive theory.

Findings

This study stated that people prefer repetitively using offensive words to achieve cyberbullying goals. Interestingly, this study does not find obvious gender differences in cyberbullying roles and cyberbullying language use. However, it explained the relationship between cognition and the use of cyberbullying words from a gender perspective.

Practical implications

Theoretically, this study expands cyberbullying studies into a new cultural environment, pointing to a novel term, “imbalanced relation,” for exploring cyberbullying behaviours. This study highlights the significance of technology and education in detecting and preventing cyberbullying, suggesting that educators and social media platforms can directly predict and prevent cyberbullying through textual perspectives and individuals' cognition of cyberbullying.

Originality/value

This study aims to examine cyberbullying linguistic and emotional features and individual differences in cyberbullying behaviour in a high-context culture like China. Its values include comparing the differences between cyberbullying in China and cyberbullying in the West from the linguistic and cultural directions and reconsidering the “power imbalance” feature of cyberbullying.

Abstract

Purpose

Participation in global value chains (GVCs) is increasingly related to the economic growth of any country. The conceivable beneficial impact of GVCs on economic growth differs across countries and could be modified with the countries' domestic institutional arrangements. However, ignoring the complementarity between the components of institutional quality led to ignorance of the institutional imbalance present in the country. Hence, the primary purpose of this study is to examine the role of institutional imbalance as a moderating variable between GVC participation and economic growth from 2000 to 2018.

Design/methodology/approach

To address the issue of endogeneity among the variables in the model, the study employs the generalized methods of moments (GMM) as an econometric analysis method.

Findings

The study finds that well-functioning domestic institutions facilitate the positive impact of GVC participation on economic growth. Conversely, an increased institutional imbalance harms the relationship between GVC participation and economic growth. These findings emphasize a balanced portfolio of institutional components. It advocates the holistic development of each component to reap greater benefits for GVC participation for any country. The study highlights that the weakness in one of the components must be addressed rather than substituted by increasing the strength of another component.

Research limitations/implications

The policies should be framed to improve the weakest component first, followed by other components of institutional quality. Simultaneous reforms involving all the dimensions of institutional quality would smoothen the path of transforming GVCs trade to the country's economic development. Additionally, the high institutional imbalance can provide a bird's eye view to policymakers to work on specific aspects of institutional quality more rigorously.

Originality/value

The existing literature has used a combined measure of institutional quality as a mediator variable while measuring the impact of GVC participation on economic growth. While using a combined measure, it ignores the complementarity among its components. Assuming substitutability among various components may lead to an incorrect estimation. Using the arguments proposed by Bolen and Sobel (2020), the present study considers the existence of complementarity among various components of institutional quality. It calculates the institutional imbalance used as a moderating variable while estimating the impact of GVC participation on economic growth.

Abstract

Purpose

The paper covers the topic of power strategies between actors and the interplay between the service ecosystem and the actor(s), and vice versa. The paper addresses the lack of conceptual development concerning power considerations beyond dyadic, rigid and role-based models found in general marketing literature. Further, the paper opens the area of power relationships, using the service ecosystem as conceptual framework.

Design/methodology/approach

The paper has a systemic and sociological view on service-ecosystems using mainly Giddens' structuration theory. Service-dominant logic literature from 2004 to 2021 is systematically reviewed for power issues and qualitatively analyzed. Mayring's step model of, firstly, inductive and, secondly, deductive category development is applied. Subcategories were identified, subsumed and finally grouped into five categories to increase the level of abstraction.

Findings

The article investigates power considerations and enables marketers to create power through (1) imbalance, to find strategies and counterstrategies for (2) actor's behavior, to understand the (3) actor's embeddedness within a service ecosystem and its dynamic nature, to learn about (4) institutions and actor's institutional work. A set of seven propositions is presented for the conceptualization of power strategies in a service ecosystem.

Research limitations/implications

The consideration of power on different levels supports both the zooming-in and zooming-out to observe and understand the power phenomena in a service ecosystem. Seven propositions about episodic as well as systemic power relations are presented. Power is conceptualized in service ecosystem as transformative capability of an actor to intervene on institutions and in some way alter them, recognizing that power relations are co-created, dynamic and context-dependent.

Practical implications

The article recognizes different levels (micro-meso-macro) of power considerations and helps practitioners and marketers to create power through (1) imbalance, find strategies and counterstrategies for (2) actor's behavior, understand the (3) actor's embeddedness within a service ecosystem and its dynamic nature, learn about (4) institutions and actor's institutional work. This enables managers to find an appropriate choice of action in their specific context to transform the service ecosystem(s) they are embedded in.

Social implications

As all social systems are power systems, a service ecosystem can only be fully understood by integrating the elementary concept of power. As such, power considerations within actor strategies and the service ecosystem are relevant to improve the understanding of transformation of the service ecosystem. Power, in the sense of the transformative capability of actors, changes the social and material world.

Originality/value

Power issues are important to understand the “hows” of resource integration in service ecosystems and its transformation or stability.
