Relic density and temperature evolution of a light dark sector
Authors: Duan Xin-Chen , Ramos Raymundo , Tsai Yue-Lin Sming
Published: September 2024

We have developed a set of four fully coupled Boltzmann equations to precisely determine the relic density and temperature of dark matter by including three distinct sectors: dark matter, light scalar, and standard model sectors. The intricacies of heat transfer between dark matter (DM) and the standard model sector through a light scalar particle are explored, inspired by stringent experimental constraints on the scalar-Higgs mixing angle and the DM-scalar coupling. Three distinct sectors emerge prior to DM freeze-out, requiring fully coupled Boltzmann equations to accurately compute relic density. Investigation of forbidden, resonance, and secluded DM scenarios demonstrates significant deviations between established methods and the novel approach with fully coupled Boltzmann equations. Despite increased computational demands, this emphasizes the need for improved precision in relic density calculations, underlining the importance of incorporating these equations in comprehensive analyses.

Continuation of Bianchi spacetimes through the big bang
Authors: Hoffmann Josh , Sloan David
Published: September 2024

In this paper we present a framework in which the relational description of general relativity can be used to smoothly continue cosmological dynamical systems through the big bang without invoking quantum gravity effects. Cosmological spacetimes contain as a key dynamical variable a notion of scale through the volume factor ν. However, no cosmological observer is ever able to separate their measuring apparatus from the system they are measuring, in that sense every measurement is a relative one, and measurable dynamical variables are, in fact, dimensionless ratios. This is manifest in the identification of a scaling symmetry or “dynamical similarity” in the Einstein-Hilbert action associated with the volume factor. By quotienting out this scaling symmetry, we form a relational system defined on a contact manifold whose dynamical variables are decoupled from scale. When the phase space is reduced to shape space, we show that there exists unique solutions to the equations of motion that pass smoothly through the initial cosmological singularity in flat Friedmann-Lemaître-Robertson-Walker, Bianchi I, and Quiescent Bianchi IX cosmologies.

Authors: Rosi P. , Viani L. , Rotunno E. , Frabboni S. , Tavabi A. H. , Dunin-Borkowski R. E. , Roncaglia A. , Grillo V.
Published: September 2024

By means of numerical simulations, we demonstrate the innovative use of computational ghost imaging in transmission electron microscopy to retrieve images with a resolution that overcomes the limitations imposed by coherent aberrations. The method requires measuring the intensity on a single pixel detector with a series of structured illuminations. The success of the technique is improved if the probes are made to resemble the sample and the patterns cover the area of interest evenly. By using a simple 8 electrode device as a specific example, a twofold increase in resolution beyond the aberration limit is demonstrated to be possible under realistic experimental conditions.

Nontrivial fusion of Majorana zero modes in interacting quantum-dot arrays
Authors: Pandey Bradraj , Okamoto Satoshi , Dagotto Elbio
Published: September 2024

Motivated by recent experimental reports of Majorana zero modes (MZMs) in quantum-dot systems at the “sweet spot,” where the electronic hopping th is equal to the superconducting coupling Δ, we study the time-dependent spectroscopy corresponding to the fusion of MZMs. The term “nontrivial” refers to the fusion of Majoranas from different original pairs of MZMs, each with well-defined parities. We employ an experimentally accessible time-dependent real-space local density-of-states (LDOS) method to investigate the nontrivial MZM fusion outcomes in canonical chains and in a Y-shaped array of interacting electrons. In the case of quantum-dot chains where two pairs of MZMs are initially disconnected, after fusion we find equal-height peaks in the electron and hole components of the LDOS, signaling nontrivial fusion into both the vacuum I and fermion Ψ channels with equal weight. For π-junction quantum-dot chains, where the superconducting phase has opposite signs on the left and right portions of the chain, after the nontrivial fusion we observed the formation of an exotic two-site MZM near the center of the chain, coexisting with another single-site MZM. Furthermore, we also studied the fusion of three MZMs in the Y-shaped geometry. In this case, after the fusion we observed the novel formation of another exotic multisite MZM, with properties depending on the connection and geometry of the central region of the Y-shaped quantum-dot array.

Signatures of the attractive interaction in spin spectra of one-dimensional cuprate chains
Authors: Shen Zecheng , Liu Jiarui , Wang Hao-Xin , Wang Yao
Published: September 2024

Identifying the minimal model for cuprates is crucial for explaining the high-Tc pairing mechanism. Recent photoemission experiments have suggested a significant near-neighbor attractive interaction V in cuprate chains, favoring pairing instability. To determine its strength, we systematically investigate the dynamical spin structure factors S(q,ω) using the density matrix renormalization group. Our analysis quantitatively reveals a notable softening in the two-spinon continuum, particularly evident in the intense spectrum at large momentum. This softening is primarily driven by the renormalization of the superexchange interaction, as determined by a comparison with the slave-boson theory. We also demonstrate the feasibility of detecting this spectral shift in thin-film samples using resonant inelastic x-ray scattering. Therefore, this provides a distinctive fingerprint for the attractive interaction, motivating future experiments to unveil essential ingredients in cuprates.

Published: September 2024

Quantum many-body systems near phase transitions respond collectively to externally applied perturbations. We explore this phenomenon in a laser-driven dissipative Rydberg gas that is tuned to a bistable regime. Here two metastable phases coexist, which feature a low and high density of Rydberg atoms, respectively. The ensuing collective dynamics, which we monitor , is characterized by stochastic collective jumps between these two macroscopically distinct many-body phases. We show that the statistics of these jumps can be controlled using a dual-tone microwave field. In particular, we find that the distribution of jump times develops peaks corresponding to subharmonics of the relative microwave detuning. Our study demonstrates the control of collective statistical properties of dissipative quantum many-body systems without the necessity of fine-tuning or of ultracold temperatures. Such robust many-body phenomena may find technological applications in sensing.

A dual opposition learning-based multi-objective Aquila Optimizer for trading-off time-cost-quality-CO2 emissions of generalized construction projects
Authors: Eirgash Mohammad Azim , Toğan Vedat
Published: September 2024

Purpose

Most of the existing time-cost-quality-environmental impact trade-off (TCQET) analysis models have focused on solving a simple project representation without taking typical activity and project characteristics into account. This study aims to present a novel approach called the “hybrid opposition learning-based Aquila Optimizer” (HOLAO) for optimizing TCQET decisions in generalized construction projects.

Design/methodology/approach

In this paper, a HOLAO algorithm is designed, incorporating the quasi-opposition-based learning (QOBL) and quasi-reflection-based learning (QRBL) strategies in the initial population and generation jumping phases, respectively. The crowded distance rank (CDR) mechanism is utilized to rank the optimal Pareto-front solutions to assist decision-makers (DMs) in achieving a single compromise solution.

Findings

The efficacy of the proposed methodology is evaluated by examining TCQET problems, involving 69 and 290 activities, respectively. Results indicate that the HOLAO provides competitive solutions for TCQET problems in construction projects. It is observed that the algorithm surpasses multiple objective social group optimization (MOSGO), plain Aquila Optimization (AO), QRBL and QOBL algorithms in terms of both number of function evaluations (NFE) and hypervolume (HV) indicator.

Originality/value

This paper introduces a novel concept called hybrid opposition-based learning (HOL), which incorporates two opposition strategies: QOBL as an explorative opposition and QRBL as an exploitative opposition. Achieving an effective balance between exploration and exploitation is crucial for the success of any algorithm. To this end, QOBL and QRBL are developed to ensure a proper equilibrium between the exploration and exploitation phases of the basic AO algorithm. The third contribution is to provide TCQET resource utilizations (construction plans) to evaluate the impact of these resources on the construction project performance.
Dislocation-based finite element method for homogenized limit domain characterization of structured metamaterials
Authors: Zona Renato , Esposito Luca , Palladino Simone , Minutolo Vincenzo
Published: September 2024

Purpose

Heterogeneous and micro-structured materials have been the object of multiscale and homogenization techniques aimed at recognizing the elastic properties of the equivalent continuum. The proposed investigation deals with the mechanical characterization of the heterogeneous material structured metamaterials through analyzing the ultimate strength using the limit analysis of the Representative Volume Element (RVE). To get the desired material strength, a novel finite element formulation based on the derivation of self-equilibrated solutions through the finite elements devoted to calculating the lower bound theorem has been implemented together with the limit analysis in Melàn’s formulation.

Design/methodology/approach

The finite element formulation is based on discrete mapping of Volterra dislocations in the structure using isoparametric representation. Using standard finite element techniques, the linear operator V, which relates the self-equilibrated internal solicitation to displacement-like nodal parameters, has been built through finite element discretization of displacement and strain.

Findings

The proposed work presented an elastic homogenization of the mechanical properties of an elementary cell with a geometry known in the literature, the isotropic truss. The matrix of elastic constants was calculated by subjecting the RVE to numerical load tests, simulated with a commercial FEM calculation code. This step showed the dependence of the isotropy properties, verified with Zener theory, on the density of the RVE. The isotropy condition of the material is only achieved for certain section ratios between body-centered cubic (BCC) and face-centered cubic (FCC), neglecting flexural effects at the nodes. The density that satisfies Zener’s conditions represents the isotropic geomatics of the isotropic truss.

Originality/value

For the isotropic case, the VFEM procedure was used to evaluate the isotropy of the limit domain and was compared with the Mises–Schleicher limit domain. The evaluation of residual ductility and dissipation energy allowed a measurement parameter for the limit anisotropy to be defined. The novelty of the proposal consisted in the formulation of both the linearized and the nonlinear limit locus of the material; hence, it furnished the starting point for further limit analysis of the structures whose elementary volume has been described through the proposed approach.

Authors: Chirakranont Rangson , Racela Olimpia C.
Published: September 2024

Learning outcomes

After reading and discussing this case study, students will be able to explain the concept of diffusion of innovation and predict how the passion fruit-infused vinaigrette (PFIV) might spread throughout the Thai market; analyze the market environment for condiments in Thailand and identify specific opportunities that Preedha Vinchit and her team should consider for the successful launch of the PFIV; interpret both qualitative and quantitative data gathered by the new product development (NPD) team and discuss its implications for the product’s market strategy and development; and critique the initial launch plan proposed by Krit Anon, suggest practical strategies and calculate the break-even point necessary to meet the project’s financial goals.

Case overview/synopsis

During July 2023, Vinchit, product marketer at the Thani Food Institute (TFI), faced a critical decision regarding the launch of the APFIV. Developed from TFI’s patented passion fruit peel powder, the PFIV offered functional benefits and addressed the sustainable use of passion fruit resources. As COVID-19 restrictions eased, TFI’s board of advisors anticipated a successful market entry for PFIV. Anon, culinologist and chef behind PFIV’s formulation, expressed keen interest in launching it independently with a startup investment of THB 500,000 (US$14,388). Vinchit, with market research and home-use test results indicating positive consumer reception in hand, contemplated whether to proceed with a launch plan of TFI’s design or endorse Anon’s entrepreneurial venture. Critical considerations included market viability, strategic partnerships, target demographics and marketing strategies encompassing pricing, distribution and promotional campaigns. The decision hinged on maximizing PFIV’s market potential amidst Thailand’s robust condiment consumption and growing health awareness.

Complexity academic level

This case study can be used in undergraduate and graduate courses in entrepreneurship, food product development, marketing strategy, market research and innovation on topics including NPD, opportunity identification, concept testing, consumer research analysis, marketing strategy formulation, business/financial analysis and launch strategies. This case study may be more useful in the middle or later parts of a course or module when an instructor is focusing on any or all stages of the NPD process and the strategic decisions, particularly for aspiring entrepreneurs with limited resources. Additionally, students should have developed at least some preliminary understanding of qualitative and quantitative research methods. This case study has been very effective in demonstrating various organizational processes and decision-making tools, which allow students to apply strategy frameworks and systematically evaluate several alternatives.

Clarifying misconception of quality and safety in healthcare
Authors: Chatzi Anna V. , Kourousis Kyriakos I.
Published: September 2024

Purpose

Healthcare has undergone multiple phases in gaining understanding, accepting and implementing quality and safety, with the last 3 decades being crucial and decisive in making progress. During that time, safety has always been quoted along with quality, but the cost of error in healthcare (both in human lives and monetary cost) has been continuing to rise.

Design/methodology/approach

This article discusses the authors’ expert perspective in comparison to the industry’s research and practice outputs.

Findings

Healthcare has not yet defined quality and safety. This is allowing the misconception that already established quality management systems (QMSs) are fit for safety purposes as well. Even though aviation has acted as a paradigm for healthcare, further alignment in embedding safety management systems (SMS) has yet to be realised.

Originality/value

In this paper, the distinct nature of safety and its detachment of quality is being discussed, along with the need for clear and safety specific processes. Setting common language is the first step in establishing appropriate safety processes within SMSs, operating in tandem with QMSs, to promote patient safety successfully.

Authors: Ominde Diana , Ochieng Edward Godfrey , Zuofa Tarila
Published: September 2024

Purpose

The purpose of this study is to examine the influence of stakeholder integration and project complexity on information technology (IT) projects in Kenya. The following research question guided our inquiry: what is the influence of project complexity and stakeholder integration on the performance of IT projects in Kenya?

Design/methodology/approach

To advance the current understanding of the effect of stakeholder integration and project complexity on IT projects, multiple regressions were used to predict how project complexity and stakeholder integration influence project performance. Both government-funded and privately funded IT projects from a developing country were examined.

Findings

The study found that any project’s complexity and stakeholder integration levels offer a distinctive contribution to its success. Theoretically, the study contributes to linkages between stakeholder integration and project complexity concerning IT project performance. Through the adoption of actionable research and theoretical elaboration, we have shown that the successful execution of IT projects is driven by the successful integration of stakeholders and monitoring the level of complexity at each phase of the project.

Originality/value

The findings of this study add to the burgeoning literature on the performance of IT projects and come with several managerial implications as well. It brings to the fore the concept of stakeholder integration as an essential element of project success. The findings suggest that the inclusion of stakeholder integration into corporate decisions, strategies and policies can be an asset to the production of sustainable competitive advantages needed during the implementation of IT projects in government entities and organisations. As shown in this study, all the above require a collaborative platform allowing for data sharing among diverse stakeholders to ameliorate distrust or lack of information.

How perceived value of augmented reality shopping drives psychological ownership
Authors: Wang Kai-Yu , Ashraf Abdul Rehman , Thongpapanl Narongsak , Iqbal Idaf
Published: September 2024

Purpose

This study proposes a framework that demonstrates how the perceived value of augmented reality (AR) shopping influences the formation of psychological ownership of product and technology. The mediating role of flow experience and the moderating role of perceived control are identified.

Design/methodology/approach

An online survey study recruiting 480 participants who experienced AR shopping was conducted to test the hypotheses.

Findings

Functional value is negatively related to psychological ownership of product and technology whereas emotional value shows opposite effects. Flow experience mediates the relationships between functional/emotional value and psychological ownership of product and technology. Perceived control moderates the relationship between emotional value and flow experience, as well as the relationship between functional/emotional value and psychological ownership of product and technology.

Practical implications

The findings suggest the importance of AR’s functional and emotional values in developing psychological ownership of product and technology. To mitigate the negative effect of functional value, AR designers should focus on creating emotionally engaging apps that induce a flow experience, thereby enhancing psychological ownership. Furthermore, AR apps should be designed to empower users with a sense of control in the AR experience.

Originality/value

This research contributes to the AR and psychological ownership literature. It introduces a model that can explain both the formation of psychological ownership of product and psychological ownership of technology, thereby expanding the current understanding. By adding perceived values as antecedents of psychological ownership, it enriches the psychological ownership literature. Moreover, it enhances the flow experience literature by demonstrating the role of flow experience in the formation of psychological ownership of product and technology.
Spirit at work: a panacea for ethical problems caused by marketing managers’ love of money
Authors: Alvi Tariq Hameed , Tariq Samia , Atif Mian Muhammad , Ozturk Ilknur , Saeed Munazza
Published: September 2024

Purpose

Limited research has investigated how spirit at work, functioning as a “good barrel,” fosters ethical decision-making (EDM) even in the presence of unethical managerial behavior (“bad apples”). Therefore, this study aims to investigate the spirit at work, a situational variable, as a moderating variable in the relationship between the love of money (LoM), an individual-level factor, and EDM.

Design/methodology/approach

A time-lagged survey of the members of the Marketing Association of Pakistan was conducted. The data were analyzed using partial least square structural equation modeling.

Findings

Adding to much of the existing research, which finds that LoM can influence ethical intention directly, this research finds that LoM influences ethical intention only through ethical judgment. Moreover, the spirit at work tempers the negative relationship between LoM and ethical judgment, thereby mitigating LoM’s detrimental effects not only on ethical judgment but also its downstream effects on ethical intention.

Practical implications

Organizations, by planting the seeds of spirit at work, can institutionalize good barrels, which can alleviate the negative effects of the marketing managers’ LoM, the root cause of unethical behavior. This way, this study establishes a business case for spirit at work.

Originality/value

The novelty of this study is the development and investigation of a holistic conceptual framework for EDM of marketing professionals that incorporates LoM as an antecedent, ethical judgment as an underlying mechanism, ethical intention as an outcome variable and spirit at work as a boundary condition.

Design/methodology/approach

The research design used was one group pretest and posttest (n = 40) students in research proposal courses.

Findings

Analysis with stacking and racking analysis showed a change in the distribution of the Logit Value Person (LVP) and Logit Value Item (LVI) values on the side of the subjects and items used for this study. Testing with a paired sample t-test yielded a value of t = −3.059 and a significance (p) = 0.004, indicating that there was a significant increase in LVP at the pre-test (M = 2.52 & SD = 1.56) and post-test (M = 3.33 & SD = 2.09) in the subject of the study.

Practical implications

The study results concluded that this academic integrity training program can improve students' academic integrity and is designed and implemented with the right personal approach to suppress academic dishonesty, especially the problem of plagiarism among graduate students submitting thesis proposals.

Originality/value

Academic dishonesty has been a major problem in higher education over the last two decades. Various strategies have been attempted to address the condition, but no program has been found to directly address the problem on the personal order or individuals who do so.
Resistance and collaboration within the panoptivarsity: differing views of ORCID in Ireland
Authors: Houghton Frank , Foster Allen Edward
Published: September 2024

Purpose

ORCID is well recognised as a Persistent Identifier (PID) amongst the global academic community. The international literature is generally extremely positive towards this development. A minority of vociferous critics however have continued to dispute its benefits. Particular concerns have been noted around the potential for ORCID to be used as a tool for evaluation and surveillance by University management structures. This research sought to critically evaluate in-depth perceptions of ORCID in the Technological University (TU) sector in Ireland.

Design/methodology/approach

This study involved ten semi-structured interviews with academics and five with librarians in the TU sector. Reflexive thematic analysis informed by Heideggerian hermeneutic phenomenological principles was used to explore transcribed interview data.

Findings

The results demonstrate a clear difference in perceptions concerning ORCID, with library staff being very positive and uncritical, even arguing for mandatory adoption. Although some academics were using ORCID IDs in a performative manner, most were suspicious of, or resigned to their use. Concerns about ORCID ranged across various issues including employer surveillance, a lack of institutional autonomy and its inappropriateness for the sector. It is argued that academics in the TU sector have so far not had an opportunity to fully explore and articulate their vision for the future. In its current form ORCID represents a foreign, imposed and inappropriate tool that may facilitate willing or unwilling inclusion in the inequitable and crude “game” of global university league tables.

Originality/value

The paper offers an in-depth and critical analysis of ORCID adoption in Ireland based on perceptions amongst two stakeholder groups: academics and librarians.
Unleashing potential: how alpha female status shape extra-role performance across life's stages and marital roles
Authors: Palo Sasmita , Menon Sreejith R.
Published: September 2024

Purpose

The present study examines the interplay between age, marital status, alpha female status and various adaptive performance dimensions among a cohort of 380 female professionals.

Design/methodology/approach

This study adopts a positivist approach to collect and analyse the data, utilizing appropriate statistical techniques to explore the relationships between the variables of interest.

Findings

The study elucidates the significant role of alpha female status in predicting adaptive performance. It finds that alpha females possess distinct competencies, particularly in learning and training, indicative of proactive behaviour and self-efficacy. While older participants tend to demonstrate higher performance levels, the study reveals no significant correlation between age and alpha female status, suggesting that leadership traits may develop independently of age. Furthermore, marital status exerts a modest influence on adaptive performance. The interplay of age and marital status significantly affects adaptive performance, potentially due to the Cumulative Advantage Paradigm, which is the accumulation of advantages or disadvantages throughout an individual's life course.

Originality/value

This study contributes to the existing literature by providing a nuanced understanding of how demographic factors converge to influence adaptive performance in professional settings. It highlights the importance of recognising and nurturing alpha females in organizations and considering the interactions between age and marital status when designing career development programmes and support systems.
Fostering newly resettled refugee-background adolescents’ self-efficacy and advocacy in a community-based youth program

Design/methodology/approach

Using a mixed-methods approach, this study examined twenty-two RBAs through survey and focus groups.

Findings

The findings reveal significant growth and transformation in the students' self-efficacy and advocacy skills. This growth underscores the critical role of social support and community engagement in helping RBAs, empowering them to advocate for themselves and others in pursuing educational and career goals.

Originality/value

This study contributes new insights into the community-based support programs for RBAs, focusing on enhancing self-efficacy and advocacy. It offers valuable implications for developing effective support frameworks and recommends future research on these approaches.
Depressive symptoms, loneliness and social support in healthcare employees: does the source of support matter?
Authors: Kulari Genta , Pereira de Castro Michelle
Published: September 2024

Purpose

Depressive symptoms are a risk factor for loneliness, while sources of perceived social support from family and friends are protective factors; however, the complex mechanisms behind these factors have not been examined among health-care employees in Portugal. The purpose of this study is to evaluate the indirect effect of perceived social support from family and friends on the association between depressive symptoms and loneliness.

Design/methodology/approach

Health-care employees (n = 279; 242 female and 37 male) from 12 health-care institutions in Portugal participated in this cross-sectional study. The SPSS program with PROCESS macro (Model 6) was used to test the hypothesis regarding the indirect effect analysis.

Findings

Bootstrap analysis found that family as a source of social support had an indirect effect in the relationship between depressive symptoms and loneliness. Similarly, depressive symptoms had a significant indirect effect on loneliness through the indirect role of social support from friends. Moreover, it was found that the relationship of family and friends as sources of social support mediated the association of the aforementioned variables.

Originality/value

The findings of this study underscore the important role of depressive symptoms on perceived social support from family and friends, leading to loneliness, which is a public health concern among health-care employees in Portugal.
The application of risk-based inspections on furnace high-pressure cooling systems incorporating proportional hazards and steam explosion consequence modelling
Authors: Lelo Nzita Alain , Heyns P. Stephan , Wannenburg Johann
Published: September 2024

Purpose

Steam explosions are a major safety concern in many modern furnaces. The explosions are sometimes caused by water ingress into the furnace from leaks in its high-pressure (HP) cooling water system, coming into contact with molten matte. To address such safety issues related to steam explosions, risk based inspection (RBI) is suggested in this paper. RBI is presently one of the best-practice methodologies to provide an inspection schedule and ensure the mechanical integrity of pressure vessels. The application of RBIs on furnace HP cooling systems in this work is performed by incorporating the proportional hazards model (PHM) with the RBI approach; the PHM uses real-time condition data to allow dynamic decision-making on inspection and maintenance planning.

Design/methodology/approach

To accomplish this, a case study is presented that applies an HP cooling system data with moisture and cumulated feed rate as covariates or condition indicators to compute the probability of failure and the consequence of failure (CoF), which is modelled based on the boiling liquid-expanding vapour explosion (BLEVE) theory.

Findings

The benefit of this approach is that the risk assessment introduces real-time condition data in addition to time-based failure information to allow improved dynamic decision-making for inspection and maintenance planning of the HP cooling system. The work presented here comprises the application of the newly proposed methodology in the context of pressure vessels, considering the important challenge of possible explosion accidents due to BLEVE as the CoF calculations.

Research limitations/implications

This paper however aims to optimise the inspection schedule on the HP cooling system, by incorporating PHM into the RBI methodology, as was recently proposed in the literature by Lelo et al. (2022). Moisture and cumulated feed rate are used as covariate. At the end, risk mitigation policy is suggested.

Originality/value

In this paper, the proposed methodology yields a dynamically calculated quantified risk, which emphasised the imperative for mitigating the risk, as well as presents a number of mitigation options, to quantifiably affect such mitigation.
Banking-as-a-service? American and European G-SIBs performance
Authors: Ben Bouheni Faten , Sidaoui Mouwafac , Leshchinskii Dima , Zaremba Bryan , Albashrawi Mousa
Published: September 2024

Purpose

The purpose of this study is to investigate how the implementation of digital banking services (mobile applications) by globally systemically important banks (G-SIBs) affects banks’ performance in the USA and Europe from 2005 to 2022.

Design/methodology/approach

The study employs advanced econometric methods to analyze the link between deposits and banking performance, utilizing linear regressions and multivariate Bayesian regressions.

Findings

Our results indicate that customer deposits positively impact a bank’s performance after the introduction of the mobile application feature of check deposits, whereas social risk negatively impacts banking financial performance. These findings support the hypothesis that technology implementation improves the profitability and growth of traditional banks.

Research limitations/implications

While findings are robust econometrically in linear and Bayesian regressions, variables reflecting the digitalization of banks remain limited. For instance, the number of mobile users or the volume of digital transactions per bank since the implementation of the mobile app is not available.

Practical implications

In a rapidly growing technology and constantly changing customers behaviors, this research has practical implications from bankers’ perspective to continue the technological innovation efforts and from regulators’ perspective to strengthen requirements for the digital banking services.

Social implications

We provide empirical evidence that including a banking app for smartphones’ users for remote banking services benefit the financial performance of banks. However, the social risk remains significant for banks in terms of customers' satisfaction, data privacy and cybersecurity.

Originality/value

This paper employs an innovative approach to create a mobile app “discriminatory” factor and examine the relationship between deposits and banks’ performance before and after the introduction of a mobile app for too-big-to-fail banks in Europe and the USA. Additionally, we consider the social risk component of the ESG score, as a bank’s decision to implement mobile applications and technology for its customers potentially affects social risks associated with customer satisfaction and technology usability.
Does employee intervention encourage or discourage the spread of dysfunctional customer behavior?
Authors: Huang Yu-Shan (Sandy) , Liu Ruping
Published: September 2024

Purpose

Dysfunctional customer behavior (DCB) is costly and problematic for organizations. This research seeks to understand how DCB spreads and how businesses can effectively deal with it through employee intervention.

Design/methodology/approach

This research conducted a survey study and an experimental study to examine the proposed model.

Findings

Through two studies, we discovered that when an employee intervenes to stop DCB and is perceived as having high coping ability, observing customers learn from the employee’s action, resulting in reduced empathy toward the dysfunctional customer and diminished intentions to engage in DCB. Conversely, if they perceive the employee as having low coping ability, the intervention backfires, enhancing the observers’ empathy toward the dysfunctional customer and consequently leading them to engage in more DCB.

Originality/value

This research unveils an additional mechanism that explains the spread of DCB. It also contributes to the employee intervention literature by shedding light on when employee intervention can backfire. Further, our application of social learning theory along with the person-situation interaction literature offers a fresh perspective in explaining service exchanges.
Police production and crime in the urban space: a systematic review of indicators, metrics and methods
Authors: Taques Fernando Henrique , Nepomuceno Thyago Celso Cavalcante
Published: September 2024

Purpose

Empirical literature is the primary source of understanding how policing can effectively reduce criminal activities. Spatial analyses can identify particular effects that can explain and assist in constructing appropriate regional strategies and policies; nevertheless, studies that use spatial regression methods are more limited and can provide a perspective on specific effects in a more disaggregated regional context.

Design/methodology/approach

This research aims to conduct a systematic literature review (SLR) to understand the relationship between crime indicators and police production using spatial regression models. We consider a combination of Kitchenham and Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocols as a methodological strategy in five bibliographic databases for collecting scientific articles.

Findings

The SLR suggests a limited amount of evidence that meets the criteria defined in the research strategy. Several particularities are observed regarding police and criminal production metrics, either in terms of aggregation level, indicator transformations or scope of analysis. A broader time perspective did not necessarily indicate statistical significance compared to models with a single-period sample.

Practical implications

The findings suggest the possibility of expanding efforts by the public sector to provide policing data with the intention of conducting appropriate research using spatial analysis. This step could allow for a more robust integration between the public sector and researchers, strengthening policing strategies, evaluating the effectiveness of public security policies and assisting in the development of strategies for future policy actions.

Originality/value

Limited empirical evidence meets the criteria of spatial regression models with temporal components considering police production and criminality indicators. Constructing an SLR with this scope is an unprecedented contribution to the literature. The discussion can enhance the understanding of approaches for studying the relationship between police efforts and crime prevention.
