Streamlining latent spaces in machine learning using moment pooling
Authors: Gambhir Rikab , Osathapan Athis , Thaler Jesse 
Published: October 2024

Many machine learning applications involve learning a latent representation of data, which is often high-dimensional and difficult to directly interpret. In this work, we propose “moment pooling,” a natural extension of deep sets networks which drastically decreases the latent space dimensionality of these networks while maintaining or even improving performance. Moment pooling generalizes the summation in deep sets to arbitrary multivariate moments, which enables the model to achieve a much higher effective latent dimensionality for a fixed learned latent space dimension. We demonstrate moment pooling on the collider physics task of quark/gluon jet classification by extending energy flow networks (EFNs) to moment EFNs. We find that moment EFNs with latent dimensions as small as 1 perform similarly to ordinary EFNs with higher latent dimension. This small latent dimension allows for the internal representation to be directly visualized and interpreted, which in turn enables the learned internal jet representation to be extracted in closed form.

Analysis of
DD*
and
D¯(*)Ξcc(*)
molecule by one boson exchange model based on heavy quark symmetry
Authors: Asanuma Tatsuya , Yamaguchi Yasuhiro , Harada Masayasu 
Published: October 2024

Numerous exotic hadrons with heavy quarks have been reported in the experiments. In such states, symmetries of heavy quarks are considered to play a significant role. In particular, the superflavor symmetry, or also called the heavy quark antidiquark symmetry is one of the interesting symmetries, which links a quark Q to an antidiquark Q¯Q¯ having the same color representation as Q. In this paper, we study a D¯Ξcc molecular state as a superflavor partner of the doubly charmed tetraquark Tcc reported by LHCb recently. Tcc locating slightly below the DD* threshold is a candidate of the hadronic molecule. Thus by replacing the singly charmed meson D(*) with the doubly charmed baryon Ξcc(*), superflavor symmetry predicts the existence of the D¯(*)Ξcc(*) bound state. We employ the one boson exchange model respecting with the heavy quark spin symmetry where the parameter is obtained to reproduce the Tcc binding energy. We apply this model with superflavor symmetry to the D¯(*)Ξcc(*) molecule and predict a bound state with I(JP)=0(12−). If the pentaquark state corresponding to D¯(*)Ξcc(*) molecular state is observed in future experiments as predicted in this work, it is more likely that Tcc is a DD* molecular state.

Unveiling the relationship between intellectual capital and corporate performance through earnings management practices
Authors: Mohapatra Swati , Pattanayak J.K. 
Published: October 2024

PurposeThis study aims to empirically investigate the relationship between intellectual capital (IC) and corporate performance (CP), including financial, market and sustainability performance. The research also investigates the mediating role of earnings management practices (EM) in the IC and CP relationship.Design/methodology/approachThe empirical connection between IC and CP for 795 nonfinancial listed Indian firms is examined for 17 years using industry and year-fixed effect panel regression models. The research has also used Baron and Kenny’s four-step model to examine the role of EM as a mediator between IC and CP.FindingsIC plays a crucial part in improving the financial, market and sustainability performance of Indian firms. The empirical findings further claim that EM practices partially mediate the connection between IC and CP. However, the mediation effect of EM depends on its magnitude and direction, i.e. income-increasing (decreasing) EM practices. The study also claims that sustainability performance-oriented firms practice less EM.Research limitations/implicationsManagers and policymakers can use the findings of this study to their advantage by focusing on the significance of IC in the Indian context and their efforts to improve financial, market and sustainability performance while limiting earnings management practices.Originality/valueThe research uncovers a novel facet of the IC–CP relationship where EM mediates between the two. To the best of our knowledge, this is the first study that analyzes the impact of IC on CP through the lens of mediation using both accrual and real earnings management.
The role of internships on engineering students’ expectations toward their first position after graduation
Authors: Vicente Sophia , Artiles Mayra , Matusovich Holly , Carrico Cheryl 
Published: October 2024

PurposeWe used a complementary mixed methods approach, grounded in situated expectancy-value theory, to explore the relationship between completing an internship and engineering undergraduate students’ preparedness and expectancy of success in obtaining their preferred first position after graduation. We disseminated a survey to institutions in the United States and received 1,583 responses; from this sample, we interviewed 62 students.Design/methodology/approachInternship experiences are considered among “high impact practices” in higher education. Despite calls to increase the quality and quantity of internships, little is known about relationships between internship participation and how prepared students feel for future work, specifically their first position after graduation.FindingsOur findings showed that the students who participated in internships had positive perceptions of preparedness and expectancy of success compared to their peers. We found that participating in multiple internships was beneficial to these outcomes until a student participated in five internships. After five internships, our data did not show a correlation between increasing numbers of internship experiences and increased preparedness or expectancy of success.Practical implicationsWhile there are benefits to internship participation, after six experiences, additional internships are unlikely to increase confidence in job success and preparation. If that still is lacking, a different approach or conversation on career choice may be warranted.Originality/valueOur findings are unique in identifying (1) the aspects of internships that increase perceptions of success, including tying theoretical concepts learned in the classroom to engineering practice and (2) the point at which further internships do not seem to offer further benefits.
Mindfulness, adversity quotient and learner satisfaction in the virtual learning environment: perspectives from Indian higher education
Authors: Patwardhan Vidya , Bajaj Gita , Sen Sujoy , Kumawat Renuka 
Published: October 2024

PurposeThis study aims to investigate the relationship between student perceived teacher mindfulness (STM), student mindfulness (SM), adversity quotient (ARP) and learner satisfaction (LS). This study likewise examined whether SM and ARP mediate the relationship between STM and LS.Design/methodology/approachA questionnaire battery of STM, self-reported SM, ARP and LS was prepared and pilot-tested. A cross-sectional survey of 2,000 students from four universities, three in India and one in the UAE was administered. In total, 713 survey responses after data cleaning were used for analysis.FindingsThe results from three-stage hierarchical multiple regression predicted that STM was the strongest predictor of LS followed by SM and ARP. The parallel mediation Model 4 from PROCESS Macro by Hayes (2013) was used to test the mediation effects of SM and ARP profile on the relationship between STM and LS. It was found that SM has a larger effect than the ARP profile on the LS of a student.Practical implicationsThe results of this study show that learner satisfaction in the virtual learning environment can improve through interventions at the institutional level by reviewing the recruitment process of faculty and students, and at the governance level by adopting processes that help address teacher challenges such as stress and anxiety.Originality/valueIn the extant literature, the studies on STM, teacher mindfulness, adversity quotient and learning satisfaction are an under-researched domain, especially in the context of virtual learning. Likewise, the adversity quotient though an established concept has not been adequately studied on students in the virtual environment.
Transformation of value in co-creation: modalities and thresholds
Authors: Chathoth Prakash K. , Ungson Gerardo R. 
Published: October 2024

Purpose
This paper aims to focus on how value is generated as part of co-creative modalities in service transactions. The progression of value creation ranges from utilitarian to hedonic and experiential value over repeated transactions that entail crossing specific thresholds that enhance deeper trust when the customer consumes the same product/service bundle over time.

Design/methodology/approach
In this paper, the authors synthesize various theoretical narratives and advance propositions for understanding the modalities and processes underlying the repeated transformation of co-creation values in repeated transactions over time.

Findings
The propositions provide a basis to investigate how the firm is able to engage with the customers to move from basic forms of value creation to more advanced forms such that the firm is able to manage the value creation modalities leading to superior value generation.

Research limitations/implications
This paper provides a basis for firms to understand how value is co-created and transformed. Specifically, the evolution of customer values is assessed from value-in-exchange and value-in-use to value-in-experience. The role of thresholds in the evolution of value is integral in the progression from utilitarian, hedonic, to experiential value. Moreover, in repeated transactions, the role of trust underpins the processes underlying different thresholds. In practice, firms should seek to engage the customer at a higher level in the creation of co-creative modalities of value creation.

Originality/value
This paper provides a theoretical context of the evolution and transformation of such value in co-creation. Extant research has yet to delve into such value creation accounts from the perspective of the firm (service provider) and its customers.
Assessment of developmental coordination disorder in adulthood: a scoping review
Authors: Armstrong Dorothy 
Published: October 2024

Purpose
Developmental coordination disorder (DCD) is a life-long condition, but the diagnostic process for adults has not been formally established. The purpose of this study was to ascertain which assessment tools are used to assign participants into the group with DCD in studies investigating this condition in adulthood.

Design/methodology/approach
A scoping review was conducted using PRISMA guidelines. Peer reviewed literature published between January 2008 and April 2024 was searched using five databases: AMED, CINAHL Ultimate, Google Scholar, PubMed and Scopus. Data was extracted using the “Joanna Briggs Institute” scoping review guidelines.

Findings
In total, 36 articles were identified as meeting the inclusion criteria for this review. The Adult Developmental Co-ordination Disorders/Dyspraxia Checklist was the most frequent tool used to measure current and past impact on occupational performance. Level of motor skill was only measured in 51% of the studies, and none of these studies used tests with norms for an adult population. The Movement Assessment Battery for Children 2 was the most commonly used tool to measure level of motor skill.

Originality/value
Findings from this scoping review could be used in the creation of a pilot pathway for the assessment of adults for DCD.
Breaking the mold: the pursuit of decentralized trade and supply chain finance
Authors: Sangari Mohamad Sadegh , So Kar Wai , Mashatan Atefeh 
Published: October 2024

PurposeBlockchain technology (BT) presents a decentralized approach that has promising potentials to alleviate many of the long-lasting risks and inefficiencies in trade finance (TF) and supply chain finance (SCF) operations, providing international traders greater access to working capital. Despite this, the actual adoption of the technology and related issues in this space has remained under-researched. This paper examines the state of the practice to identify the main drivers and inhibitors faced by TF/SCF parties in their BT adoption efforts.Design/methodology/approachThis exploratory study applies a multi-stakeholder perspective and a mixed-methods approach using semi-structured interviews with practitioners in various stages of BT implementation in TF/SCF initiatives across North America, Europe and Asia. The study then determines the priority of the identified factors using the Bayesian best-worst method (BWM).FindingsThe findings show that while the discussion has focused on the technological drivers of BT adoption for TF/SCF, practitioners rely more on non-technological factors such as peer adoption and fostering innovation. The findings also reveal how practitioners address common BT issues, including scalability and interoperability.Originality/valueThe study offers insights into important requirements for realizing the full benefits of BT in support of TF and SCF from an extended technology-organization-environment (TOE) perspective. On a more general level, it highlights what is required to transform this industry toward digitization.
Gender stereotypes in robotics in the field of tourism and hospitality. A conceptual paper
Authors: Otegui Carles Almudena , Fraiz Brea José Antonio , Araújo Vila Noelia 
Published: October 2024

Purpose
It is imperative to develop studies on robotics through a gender lens, as gender equality is crucial for advancing innovations within the field of tourism and hospitality. This paper aims to open new research questions based on the concept of gender stereotypes in robotics in the field of tourism and hospitality, critically examining how gender and gender stereotypes are being addressed in the current state of knowledge.

Design/methodology/approach
Conceptual papers focus on analysing concepts, approaching problems to address “what’s new” and highlighting directions for future thinking. They contribute fresh perspectives to traditional problems. Despite their potential to broaden our thinking, conceptual papers in tourism research are limited.

Findings
The importance of the concept of gender stereotypes in robotics in the field of tourism and hospitality presented in this conceptual paper is evident in recognising that robotics poses numerous ethical challenges aimed at preventing the replication and perpetuation of gendered norms, biases, prejudices and stereotypes prevalent in society. Overlooking these aspects during the design and utilisation of robots could inadvertently amplify discriminatory biases, enable abusive behaviours and contribute to the continued objectification of female workers within the tourism and hospitality sector.

Originality/value
While the concept of gender stereotypes in robotics is not novel, what is indeed novel is the untested relationship between gender stereotypes in robotics and the field of tourism and hospitality. Additionally, the context in which this relationship is presented is fresh, as it has typically been discussed in relation to customer acceptance, believability, perceived quality or satisfaction in interactions with robots. However, this paper’s distinctiveness lies in its exploration of the potential impact of robotics on either reducing or exacerbating gender stereotypes within society.

Authors: Alimusa La Ode , Ratnasari Ririn Tri , Hasib Fatin Fadhilah 
Published: October 2024

Purpose
This study presents a systematic literature review of halal food (HF) customer behaviour using the Scopus and Web of Science (WoS) databases. This study aims to identify trends, methodologies, theoretical developments and determinants of HF customer behaviour in Indonesia and Malaysia, as well as potential future research directions.

Design/methodology/approach
This study extends the bibliometric and systematic literature review covering all variables in customers purchasing HF by extracting the Scopus and WoS databases. We used the SLR method via the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) model. A total of 43 samples related to customer behaviour towards HF articles were identified and reviewed.

Findings
This study found 43 articles discussing variables or factors that influence consumers’ behaviour towards HF in Indonesia and Malaysia. Quantitative methods and extended TPB theory are most widely used to measure the determinants of customer behaviour towards HFs. Religiosity, attitude, halal awareness and trust are the most dominant factors that significantly influence customer behaviour towards HF. This study suggests several potential future research directions.

Research limitations/implications
The HF industry, marketers and governments in Indonesia and Malaysia must ensure that their products meet consumer expectations by implementing halalan thayyiban and strengthening HF marketing strategies based on halal-labelled food.

Originality/value
This study is the first to examine the factors determining customer behaviour towards HF in Indonesia and Malaysia using a systematic literature review method from Scopus and the WoS database.

Authors: Wang Xiangyang , Liu Zhiyi , Lei Xuefei 
Published: October 2024

Purpose
This paper aims to investigate how digital orientation affects digital process innovation from the dual perspectives of knowledge and capability. It also stresses the mediating effects of digital knowledge creation and strategic flexibility on this relationship, as well as the moderating effect of strategic flexibility on the relationship between digital knowledge creation and digital process innovation.

Design/methodology/approach
This paper adopted knowledge- and capability-based views to develop the theoretical model. A total of 193 samples from China were collected to test the model and hypotheses by the partial least squares structural equation modeling method.

Findings
The results indicate that digital orientation promotes knowledge creation and strategic flexibility respectively, which in turn facilitates digital process innovation. Also, the effect of digital knowledge creation on digital process innovation is moderated by strategic flexibility.

Originality/value
This study adopts the dual perspectives of knowledge and capability to deepen the relationship between digital orientation and digital process innovation by introducing digital knowledge creation and strategic flexibility as the crucial links, which responds to the call for attaching importance to digital process innovation.
Measuring the time-invariant and time-varying technical efficiency of ports in Tunisia: a stochastic frontier analysis
Authors: Ben Mabrouk Mohsen , Hammami Sami , Ouertani Mohamed Nejib 
Published: October 2024

PurposeIn Tunisia, foreign commercial exchanges are predominantly maintained via ocean freight and accomplished through eight major ports. The latter play a critical role in the Tunisian economy, whereby nearly 30.7 million tons of goods were transited in 2018. Maintaining their efficiency therefore remains a very important objective to achieve. In this context, the present study is designed to investigate the technical efficiency of respective Tunisian ports over the 16-year period (2005–2020).Design/methodology/approachThe stochastic frontier analysis (SFA) method is applied to measure the associated time-invariant and time-varying technical efficiency. Moreover, through technical inefficiency modeling, effects of both rail connectivity and private sector participation in handling activities on technical efficiency have also been accounted for.FindingsThe reached results turn out to reveal well that the Tunisian ports appear to operate below their production frontier, noticeably marked by persistent technical inefficiency. Additionally, the relevant estimates tend to confirm the berth variable associated importance in highlighting production related to Tunisian ports. More particularly, our analysis reveals that the private sector’s participation proves to display a significantly negative association with technical efficiency, while the ports’ rail connectivity turns out to demonstrate a significantly positive correlation with technical efficiency.Practical implicationsThe findings of this study can provide port authorities and policymakers with insights into the technical efficiency of Tunisian ports by identifying best practices, the main factors influencing their efficiency (such as rail connectivity and private sector’s participation) and areas for improvement in these ports.Originality/valueThe present study stands as a pioneering attempt to examine the efficiency dimension through the implementation of panel data estimation modeling frameworks, particularly the random-effects and the Battese and Coelli (1995) approaches, applied to measure the technical efficiency of the Tunisian port sector. Similarly, the present study also represents an effective attempt, whereby the effects of exogenous variables, notably the rail connectivity and private sector participation, are thoroughly considered in exploring the technical efficiency of Tunisian ports.
