Published: July 2024

AbstractIn the elderly, degenerative diseases often develop differently over time for individual patients. For optimal treatment, physicians and patients would like to know how much time is left for them until symptoms reach a certain stage. However, compared to simple disease detection tasks, disease progression modeling has received much less attention. In addition, most existing models are black-box models which provide little insight into the mechanisms driving the prediction. Here, we introduce an interpretable-by-design survival model to predict the progression of age-related macular degeneration (AMD) from fundus images. Our model not only achieves state-of-the-art prediction performance compared to black-box models but also provides a sparse map of local evidence of AMD progression for individual patients. Our evidence map faithfully reflects the decision-making process of the model in contrast to widely used post-hoc saliency methods. Furthermore, we show that the identified regions mostly align with established clinical AMD progression markers. We believe that our method may help to inform treatment decisions and may lead to better insights into imaging biomarkers indicative of disease progression.

The effect of laser pulse duration on energy coupling into a planar silicon target is investigated in experiments at the OMEGA-EP facility by varying the laser pulse length τ—spanning 3 orders of magnitude from 100 ps to 10 ns—while maintaining a constant peak laser intensity, I0=5×1014 W/cm2. In theoretical models, the ablation pressure primarily scales for a given material with laser intensity and wavelength, which are all fixed variables here, allowing us to explore the specific role of laser pulse duration. Two-dimensional radiation-hydrodynamics simulations benchmarked with optical probing of the expanding plasma show that the pulse duration is critical for the ablation pressure to reach a steady state. Moreover, the pulse duration impacts shock decay and multiple wave effects, which strongly dictate the evolving shock profile that propagates within the laser-shocked target as ultimately measured by rear-surface diagnostics. The shock velocities inferred from the theoretical model, after considering shock decay, impedance matching, and shock Hugoniot, are found to be in good agreement with velocimetry measurements. However, discrepancies are observed with simulations for the shorter (0.1 ns) and longer (10 ns) pulse durations, which are respectively attributed to unaccounted contributions of kinetic absorption mechanisms and instabilities in simulations.

We report on a quantum critical behavior in the quasi-1D spin-1/2 zigzag frustrated chain antiferromagnet CaCoV2O7, induced by an applied magnetic field. Below TN=3.3 K our zero-field neutron diffraction studies revealed the up-up-down-down spin structure, stabilized by an order-by-disorder phenomenon. At base temperature, the magnetic order is suppressed by an applied magnetic field (B), inducing a transition into a quantum paramagnetic state at Bc=3 T, as revealed by both neutron diffraction and ESR data. The transition exhibits an unusually sharp phase boundary with the critical exponent ϕ=0.164(3)≈1/6, in contrast to the earlier experimental observations for uniform spin-1/2 chain systems. Such a sharp QPT is anticipated due to a rare combination of spin-orbit coupling and competing NN and NNN exchange interactions J1 and J2 of the zigzag spin chain.

Authors: Kim Heather Markham , Kim Jungsun (Sunny) , Joo Kyuhyeon , Hwang Jinsoo 
Published: July 2024

PurposeThis study investigated the impacts of the technology acceptance model (TAM) determinants and image congruence on attitude and, in turn, behavioral intentions. In addition, the differences between the US and Korean consumers in terms of the predictors of attitude were assessed.Design/methodology/approachThe data were collected via an online survey from 342 South Korean and 353 American consumers who patronized a restaurant within a three-month timeframe.FindingsThe findings revealed that two dimensions of TAM and three sub-factors of self-image congruence positively affected customer attitude toward face recognition (FR) payment. Customer attitude also significantly influenced behavioral intentions toward FR payment. Lastly, the cultural differences between the Korean and American consumers played significant moderating roles in the relationships between perceived usefulness and attitude as well as between actual self-image congruence and attitude.Originality/valueNo prior empirical research has incorporated cultural differences into the FR payment acceptance model. Unlike previous research, the current study included cultural differences as a moderator of the relationships between the five predictors (i.e. two predictors from TAM and three dimensions of self-image congruence) and attitude toward FR payment in the research model.

Authors: Hazaimeh Manar , Al-Ansi Abdullah M. 
Published: July 2024

PurposeArtificial intelligence (AI) is constantly evolving and is poised to significantly transform the world, affecting nearly every sector and aspect of society. As AI continues to evolve, it is expected to create a more dynamic, efficient and personalized education system, supporting lifelong learning and adapting to the needs and pace of each student. In this research, we focus on testing the model of AI acceptance in higher education (HE) through human interaction-based factors including attitudes, competencies and openness to experience. Perceived benefits were our expectation to enhance AI acceptance in HE.Design/methodology/approachTo test the model, we collected data from Arab HE institutions by spreading an online questionnaire. The sample consisted of 1,152 of teaching staff and students in Arab region, which were selected randomly. Partial least squares structural equation modeling (PLS-SEM) was employed to determine the interrelated dependence of relationships among variables. Furthermore, processing analysis was conducted to ensure the reliability and validity of questionnaires, multicollinearity and factor loading, in which the items were tested one more time to ensure their validity after translation into Arab language.FindingsResults reveal that adopted attitude, digital competency and openness to experience have positive and significant relationship with both perceived benefits and AI acceptance in HE in the Arab region. The results also demonstrate the indirect impact of digital factors on AI acceptance in existence of perceived benefits, which was important in the validation of the model.Originality/valueThe research contributes to AI acceptance theory and research by providing evidence of AI acceptance in the Arab region. As generative AI applications continue to expand and change, the way we accept and interact with them will be different. This model could be adopted by authorities to facilitate the acceptance of AI in Arab HE institutions.
Amplifying commitment and word-of-mouth in fashion retailing through omni-channel experiences
Authors: Akturan Ulun , Kuter Deniz 
Published: July 2024

PurposeThis study aims to explore the effects of the omni-channel experience on customer commitment and word-of-mouth (WOM) intention within the context of fashion retailing in an emerging country, Türkiye.Design/methodology/approachIn the study, data was collected online from 346 consumers. The hypothesised relationships were tested using SEM via AMOS.FindingsThree sub-dimensions of the omni-channel experience are validated, namely consistency, connectivity, and personalisation, and while consistency and personalisation positively affected customer commitment, they did not indicate any direct influence on WOM intention. On the other hand, connectivity affected WOM intention but not customer commitment. In conclusion, even though consistency, connectivity, and personalisation constitute the omni-channel experience, they have differing behavioural outcomes. Furthermore, fashion retail customers’ commitment positively influenced WOM intentions.Research limitations/implicationsThis study contributes to the literature in four main areas: First, this study validates the omni-channel experience scale. Secondly, it extends social exchange theory in omni-channel retailing research. Thirdly, it develops a micro-perspective on the omni-channel experience. Lastly, it puts forth that the effects of consistency, connectivity, and personalisation on customer commitment and WOM intention differ.Practical implicationsThe omni-channel experience is a multi-dimensional concept. Retail managers should invest in consistency, connectivity, and personalisation to amplify customer commitment and WOM intention.Originality/valueThis study explores how customer commitment and WOM intention are enhanced through an omni-channel experience.
Detection of bridge damage through analysis of dynamic response to vehicular loads utilizing long-gauge sensors
Authors: Saifeldeen Mohamed , Monier Ahmed , Fouad Nariman 
Published: July 2024

PurposeThis paper presents a novel method for identifying damage in reinforced concrete (RC) bridges, utilizing macro-strain data from distributed long-gauge sensors installed on the concrete surface.Design/methodology/approachThe method relies on the principle that heavy vehicles induce larger dynamic vibrations, leading to increased strain and crack formation compared to lighter vehicles. By comparing the absolute macro-strain ratio (AMSR) of a reference sensor with a network of distributed sensors, damage locations can be effectively pinpointed from a single data collection session. Finite-element modeling was employed to validate the method's efficacy, demonstrating that the AMSR ratio increases significantly in the presence of cracks. Experimental validation was conducted on a real-world bridge in Japan, confirming the method's reliability under normal traffic conditions.FindingsThis approach offers a practical and efficient means of detecting bridge damage, potentially enhancing the safety and longevity of infrastructure systems.Originality/valueOriginal research paper.

Understanding trust and rapport in hotel service encounters: extending the service robot acceptance model
Authors: Song Xiaoxiao , Gu Huimin , Ling Xiaodie , Ye Weijiao , Li Xiaofei , Zhu Zhisheng 
Published: July 2024

Purpose
Drawing on the Service Robot Acceptance Model (sRAM) proposed by Wirtz et al. (2018), this study aims to examine how functional and social-emotional antecedents affect relational elements and the critical functions that trust and rapport play in robot acceptance in hotel services. Additionally, this study incorporates customer characteristics into the modified sRAM.

Design/methodology/approach
Consistent partial least squares (PLSc) was used to test the proposed model utilizing data collected from 456 Chinese customers.

Findings
The results indicated that effort expectancy and performance expectancy positively affect hotel guests’ trust toward and rapport with service robots. However, the effect of social influence on trust and rapport is insignificant. Additionally, perceived humanness and perceived social interactivity positively influence rapport, and perceived social presence positively affects both trust and rapport. Furthermore, trust and rapport positively influence hotel guests’ acceptance of service robots. The results also revealed the moderating role of age.

Originality/value
This study contributes to service robot literature by providing insights into how functional and social-emotional factors affect relational factors and the key role of relational factors in robot acceptance based on the sRAM. This study also advances this body of knowledge by highlighting the moderating effect of age.
Psychometric properties of a scale to measure social entrepreneurship competency in Mexican university students
Authors: Alcantar-Nieblas Carolina , Glasserman-Morales Leonardo David , Vázquez-Parra José Carlos 
Published: July 2024

Purpose
The purposes of this study were to calculate the confirmatory factor analysis in the measurement model using robust measures (McDonald’s omega and Cronbach’s alpha) to ensure the reliability of the proposed scale and to explore the measurement invariance of the scale per the participants’ gender.

Design/methodology/approach
The methodological sample had 408 students from a private university in northern Mexico, of which 200 (49%) were male and 208 (51%) were female; the sample age range was 18–58 years (M = 22.4 years, SD = 6.0). The data analysis included descriptive and normality, dimensionality, reliability and measurement invariance.

Findings
The social entrepreneurship competency measurement model showed acceptable adjustment indexes in evaluating the internal structure, reliability and factorial invariance by gender of the study participants.

Research limitations/implications
Even though the contributions of this study are evident, these findings must be taken with caution due to some limitations. First, the proposed measurement model uses a self-reported scale, so it is essential to include other measurement methods with less implicit social desirability. Second, although the sample was intended to be representative, it only drew from a specific geographical area, making it difficult to generalize these findings to culturally diverse areas. Third, this study did not consider other validity measures; for example, concurrent, divergent and predictive, so future studies should consider examining the relationship of social entrepreneurship with other factors.

Practical implications
From the practical perspective, this study provides a parsimonious instrument regarding the number of items included in the measurement model. From the theoretical perspective, the present study contributes to delimiting the dimensions of social entrepreneurship competency.

Originality/value
This study contributes to the field of social entrepreneurship, particularly in the area of construct measurement, by offering a measurement model with solid evidence of internal structure validity, reliability and factorial invariance for the perceived achievement of social entrepreneurship competency.
Elastic and anisotropic properties of organic‐rich lacustrine shales: An experimental study
Authors: Cai Zhenjia , Zhao Luanxiao , Long Teng , Ma Jiqiang , Wang Yang , Lei Yuhong , Zhou Jiaquan , Han De‐hua , Geng Jianhua 
Published: July 2024

AbstractExperimental investigation of the elastic behaviours of lacustrine shales remains sparse, although they play an essential role in source rock evaluation, unconventional reservoir exploration and development, and the seal integrity evaluation for geological storage of CO2 and nuclear waste disposal. We make the ultrasonic velocity measurement of 63 organic‐rich shale samples (Chang 7, Qingshankou and Lucaogou formation) from three typical lacustrine basins in China. It is found that the P‐ and S‐wave velocity of Chang 7 and Qingshankou shale corresponding to the fresh‐brackish lacustrine depositional environment is mainly impacted by the clay and organic matter content, whereas their elastic anisotropic magnitude is mostly influenced by clay content. The P‐ and S‐wave velocities of Lucaogou shale corresponding to the saline lacustrine depositional environment are mainly affected by the total organic carbon and porosity and exhibit weak anisotropy linked to organic matter enrichment. Exponential law well captures the relationship between anisotropic magnitude and velocity perpendicular to bedding for both saline and fresh‐brackish water lacustrine shales, although there exists notable discrepancy, particularly at low velocities. The disparity in elasticity between laminations has a profound impact on the magnitude of elastic anisotropy and shapes the trend of velocity variations.
“Enlightened Man Incarnate”: Mediating Enlightenment in Eighteenth‐Century Literary Reviews
Authors: WAINWRIGHT VALERIE 
Published: July 2024

Abstract‘Crucial to the Enlightenment’, Roy Porter argued, was the work of ‘critics, knowledge‐mongers, and opinion‐makers’; the critic was ‘enlightened man incarnate’. In order to enhance our understanding of the ways in which exponents of print culture sought to orient public opinion and promote recognizably liberal principles and values, this article will examine both the polemical discourses of prolific literary journalists and the intellectual context of key issues, highlighting the work of the lawyer Owen Ruffhead. In often substantive commentaries, Ruffhead and his fellow critics referenced a distinctive set of natural law principles: they celebrated the norms of right reason, of equity and liberty. Amongst the values expounded in the Reviews were Lockean political precepts congruent with core features of liberal theory. From the mid‐eighteenth century, an early and unfamiliar ‘liberal’ vocabulary and agenda can be traced as civil liberties and rights were advocated, including the rights of the colonists, the underprivileged and the exploited. Decades before the term liberalism was devised, critics contributed to the shaping and diffusion of recognizably liberal patterns of thinking. Such an inquiry into a vibrant domain of ideas engages in ongoing historiographical debates, providing a new perspective on the formation and diffusion of influential ethical and socio‐political modes of thought.
