Dreaming digital or chasing new real pathways? Unveiling the determinants shaping Saudi youth's digital entrepreneurial intention
Authors: Aloulou Wassim , Ayadi Faouzi , Ramadani Veland , Dana Léo-Paul 
Published: June 2023

PurposeThe purpose of this study, based on the theory of planned behaviour (TPB) and digital entrepreneurship literature, is to unveil the role of digital entrepreneurial knowledge and entrepreneurial role models in shaping digital entrepreneurial intentions (DEIs) among Saudi Youth through a moderated mediation perspective. This study aims to propose that the relationship between digital entrepreneurial knowledge and intention is mediated by main TPB antecedents under the moderating role of entrepreneurial role models.Design/methodology/approachData were collected from a sample of 487 Saudi students from three main Saudi public universities located in Riyadh using an online survey questionnaire. By applying SEM, this study builds and tests the measurement and structural models to examine the hypothesised relationships among main variables.FindingsResults revealed that the main antecedents of TPB (namely, attitudes towards digital entrepreneurship and perceived control behaviour) are significantly related to DEI. In addition, digital entrepreneurial knowledge indicates indirect effects on intentions via these two antecedents. However, entrepreneurial role models exert only a negative and significant moderating effect on the relationship between perceived behaviour control and DEI.Research limitations/implicationsThis study contributes to the literature by showing how most of the TPB antecedents can play a mediating role between digital entrepreneurial knowledge and the intentions of Saud Youth. The main limitation of this study is that it was not possible to generalise the findings. Future research directions are proposed to add new insights.Practical implicationsThe results of this study have clear implications for both theory (entrepreneurship scholars) by investigating DEI and its determinants and for practice (entrepreneurship educators and policymakers) by promoting digital entrepreneurship among youth through university-based awareness and building capability programs and curricula.Originality/valueThe study helps to understand the role of digital entrepreneurial knowledge in shaping DEI through the development of an extended TPB intention-based model. The findings also indicate that digital entrepreneurial knowledge has indirect effects on Youth's intentions. The findings show insights related to the influence of entrepreneurial role models on TPB antecedents in the transitional context of Saudi Arabia.

Authors: Ishak Nur Faiza , Thiruchelvam Vinesh 
Published: June 2023

Purpose
The purpose of this study is to discuss policy review in the interest of sustainable innovations in Malaysia’s public procurement. This study also offers the overall relationship between existing policies related to sustainable innovations in public procurement and the coherences towards the four dimensions of sustainable innovations.

Design/methodology/approach
This study outlines the current policies in Malaysia which are related to sustainable innovation initiatives and explores the cohesiveness that appears disconnected and understood separately. Policy content analysis is conducted on the current policies related to sustainable innovations in the context of Malaysia’s public procurement.

Findings
This study observed that the current policies related to sustainable innovations in public procurement are actually interconnected with each other through a hierarchical framework. This study also demonstrates that the 12th Malaysia Plan has comprehensively encompassed every aspect of the environment, social, economic and innovation to contribute to one primary goal – green economic growth.

Research limitations/implications
The proposed policy framework is expected to be beneficial for the administrator executive among the civil servant to connect the independent policies and, at the same time, contribute to the overall goal of green economic growth. Through a broad policy structure too, this study helps the industry player to recognize their potential in any area related to sustainable innovation.

Originality/value
The policy framework illustrated is new to the literature, especially in Malaysia’s context. The compilation of current policy grounded by the 12th Malaysia Plan has not been presented in any publications.
Does green innovation mediate corporate social responsibility and environmental performance? Empirical evidence from emerging markets
Authors: Bonsu Mandella Osei-Assibey , Guo Yongsheng , Zhu Xiaoxian 
Published: June 2023

PurposeThis paper examines the mediation role of green innovation in the relationship between corporate social responsibility and environmental performance of manufacturing firms in Ghana.Design/methodology/approachThe paper chose African emerging markets and surveyed managers from manufacturing firms. With 301 questionnaires qualified for this study’s final analyses, the authors adopt the multiple regression with mediation models to estimates the nexus among study variables.FindingsResults evidence that both corporate social responsibility and green innovation has a positive and significant impact on environmental performance. Interestingly, the authors find that corporate social responsibility significantly improves environmental performance through green innovation indicating that firms could essentially build their dynamic resource and innovation capabilities in sustainability leading to enhanced environmental performance.Research limitations/implicationsThis paper develops a dynamic resource-based view of firm environmental performance illustrating how firms use resources to build strategic capabilities for competitive advantage, which leads to improved environmental performance. The paper highlights the mediation role of green innovation on corporate social responsibility and environmental performance relationships.Practical implicationsThis study's results provide significant insights to owners and managers of manufacturing companies to integrate corporate social responsibility and green innovation to ensure environmental performance and sustainability. Furthermore, policy makers should encourage green innovation when design sustainable development systems in the manufacturing industry.Originality/valueThe paper provides a valuable model showing how green innovation mediates corporate social responsibility to improve environmental performance and build competitive advantages considering both small, medium, and large manufacturing enterprises in emerging countries.
Cyberspace as a fifth dimension of national security: trade measure exceptions
Authors: Garibaldi Stephanie , Deane Felicity 
Published: June 2023

Purpose
The purpose of this paper is to demonstrate that the national security exception will not allow governments to respond to cyberspace threats within the confines of the world trade organization (WTO) rules.

Design/methodology/approach
This paper is a desktop study of international trade laws with a specific focus on the convergence of cybersecurity measures and the national security exception provisions of the WTO.

Findings
The trends towards cybersecurity measures may mean there will inevitably be an evolution of trade norms. The question is, will the collective of the WTO be a part of the evolution, or merely an observer? In the authors’ view, it is crucial that it is the former.

Originality/value
This study makes three contributions. It provides a literature review and discussion on cybersecurity and the impact on trade. It demonstrates that the national security exception provision will not excuse these measures, and it aims to underscore the importance of the WTO as a community of nations where negotiation on important global issues is possible.
Toward Black abolition theory within radical abolition studies: upending practices, structures, and epistemes of domination
Authors: Turner Kia , Wallace Darion , Miles-Langaigne Danielle , Deras Essence 
Published: June 2023

Purpose
This study aims to present radical abolition studies, which encourages us to (re)member that the abolition of institutions and systems is incomplete without the abolition of their attendant epistemes of domination. The authors draw on the etymology of the word radical to encourage abolitionist praxis to grab systemic harm at its epistemological roots. Within radical abolition studies, this study presents Black abolition theory, which aims to make explicit a theorization of Blackness and works to abolish the episteme of anti-Blackness.

Design/methodology/approach
This paper offers Black abolition theory within radical abolition studies to reground abolition in its Black theoretical roots and to interrogate the concept of anti-Blackness and other epistemes of domination in abolitionist study and practice. Using a close reading of W.E.B. Du Bois’ Black Reconstruction, and subsequent books and articles in abolition studies and educational studies that reference it, the authors highlight Du Bois’ original conceptualization of abolitionism as an ultimate refutation of a racial-social order and anti-Blackness. The authors then put Michael Dumas and kihana ross’ theory of BlackCrit into conversation with abolitionist and educational theory to push forward Black abolition theory.

Findings
Radical abolition studies and its attendant strand of Black abolition theory presented in this paper encourages scholars and practitioners to go beyond the dismantling of current instantiations of systemic harm for Black and other minoritized people – such as the school as it currently operates – and encourages the questioning and dismantling of the epistemes of domination sitting at the foundation of these systems of harm.

Originality/value
Black abolition theory contextualizes abolition in education by rooting abolitionist educational praxis in Black lineages. More generally, radical abolition studies encourages further research, study and collaboration in partnership with others who have historically participated in the fight against being labeled as subhuman to upend all epistemes of domination.
Developing student's skills and work readiness: an experiential learning framework
Authors: Shore Adam , Dinning Track 
Published: June 2023

PurposeThis paper outlines a contemporary conceptual framework for the embedding of experiential learning into a business consultancy module. Experiential learning is a fundamental teaching approach that allows students to apply theory into a working business context.Design/methodology/approachAs a conceptual and not an empirical paper, the methodological approach was to draw upon the literature reviewed and to build a framework to support student learning through a business consultancy module.FindingsExploration of the literature suggests that there are four elements critical to student learning in experiential learning environments: action, reflection, social and context. A framework has been developed utilising these elements with the interaction between the factors being key to developing learning.Research limitations/implicationsSo far, the framework is conceptual, and further research is needed to explore its use when staff members are developing these types of modules and to understand the interaction of the factors over the course of the student learning experience.Originality/valueThe originality comes from the intersection and interaction between the core factors in experiential learning, which enables this framework to move thinking beyond more static models and hence work in a more fluid student learning environment.

AbstractHutchinson‐Gilford progeria syndrome (HGPS) is a premature aging disorder affecting tissues of mesenchymal origin. Most individuals with HGPS harbor a de novo c.1824C > T (p.G608G) mutation in the gene encoding lamin A (LMNA), which activates a cryptic splice donor site resulting in production of the toxic “progerin” protein. Clinical manifestations include growth deficiency, lipodystrophy, sclerotic dermis, cardiovascular defects, and bone dysplasia. Here we utilized the LmnaG609G knock‐in (KI) mouse model of HGPS to further define mechanisms of bone loss associated with normal and premature aging disorders. Newborn skeletal staining of KI mice revealed altered rib cage shape and spinal curvature, and delayed calvarial mineralization with increased craniofacial and mandibular cartilage content. MicroCT analysis and mechanical testing of adult femurs indicated increased fragility associated with reduced bone mass, recapitulating the progressive bone deterioration that occurs in HGPS patients. We investigated mechanisms of bone loss in KI mice at the cellular level in bone cell populations. Formation of wild‐type and KI osteoclasts from marrow‐derived precursors was inhibited by KI osteoblast‐conditioned media in vitro, suggesting a secreted factor(s) responsible for decreased osteoclasts on KI trabecular surfaces in vivo. Cultured KI osteoblasts exhibited abnormal differentiation characterized by reduced deposition and mineralization of extracellular matrix with increased lipid accumulation compared to wild‐type, providing a mechanism for altered bone formation. Furthermore, quantitative analyses of KI transcripts confirmed upregulation of adipogenic genes both in vitro and in vivo. Thus, osteoblast phenotypic plasticity, inflammation and altered cellular cross‐talk contribute to abnormal bone formation in HGPS mice.

Long‐term oncological outcome of reduced‐port laparoscopic surgery (single‐incision plus one port) as a technical option for rectal cancer
Authors: Ishii Yoshiyuki , Ochiai Hiroki , Sako Hiroyuki , Watanabe Masahiko 
Published: June 2023

AbstractBackgroundThe purpose of this study was to clarify the oncological safety of reduced‐port laparoscopic surgery (single‐incision plus one port) (RPS) for patients with rectal cancer.MethodsThe clinicopathological data of 63 selected patients with clinical Stage I‐III (T1‐3 and N0‐2) rectal cancer who underwent RPS of radical anterior resection between 2012 and 2017 were retrospectively analyzed. The median distance of tumor from anal verge was 11 cm. Ordinarily, a multiport platform with three channels was placed in the 3‐cm umbilical incision, and another 5‐ or 12‐mm port was placed in the right lower abdomen.ResultsThe median operative time, amount of intraoperative bleeding, number of harvested lymph nodes, and length of distal margin were 272 min, 10 mL, 22 nodes, and 4.0 cm, respectively, and there was one (2%) patient with involvement of the radial margin. There were eight patients (13%) who required additional ports, and one patient (2%) who converted to open surgery. Intra‐ and postoperative complications occurred in one (2%) and 12 patients (19%), respectively. The median length of postoperative hospital stay was 8 days. The median follow‐up period was 79 months, and incisional hernia was observed in 3 (5%) patients at the platform site not the port site, and cancer recurrence occurred in four patients (6%). The 5‐year relapse‐free and overall survival rates were 100% and 100% in the patients with pathological Stage I disease, 94% and 100% in the patients with pathological Stage II disease, and 83% and 89% in the patients with pathological Stage III disease, respectively.ConclusionRPS in the selected patients with rectal cancer, performed by an expert laparoscopic surgeon, may be technically safe and oncologically acceptable as well as multiport laparoscopic surgery.
Bayesian Model Selection for Generalized Linear Mixed Models
Authors: Xu Shuangshuang , Ferreira Marco A. R. , Porter Erica M. , Franck Christopher T. 
Published: June 2023

AbstractWe propose a Bayesian model selection approach for generalized linear mixed models (GLMMs). We consider covariance structures for the random effects that are widely used in areas such as longitudinal studies, genome-wide association studies, and spatial statistics. Since the random effects cannot be integrated out of GLMMs analytically, we approximate the integrated likelihood function using a pseudo-likelihood approach. Our Bayesian approach assumes a flat prior for the fixed effects and includes both approximate reference prior and half-Cauchy prior choices for the variances of random effects. Since the flat prior on the fixed effects is improper, we develop a fractional Bayes factor approach to obtain posterior probabilities of the several competing models. Simulation studies with Poisson GLMMs with spatial random effects and overdispersion random effects show that our approach performs favorably when compared to widely used competing Bayesian methods including deviance information criterion and Watanabe–Akaike information criterion. We illustrate the usefulness and flexibility of our approach with three case studies including a Poisson longitudinal model, a Poisson spatial model, and a logistic mixed model. Our proposed approach is implemented in the R package GLMMselect that is available on CRAN.
A Fully Integrated Pipeline for Visual Carotid Morphology Analysis
Authors: Eulzer P. , von Deylen F. , Hsu W.‐C. , Wickenhöfer R. , Klingner C. M. , Lawonn K. 
Published: June 2023

AbstractAnalyzing stenoses of the internal carotids – local constrictions of the artery – is a critical clinical task in cardiovascular disease treatment and prevention. For this purpose, we propose a self‐contained pipeline for the visual analysis of carotid artery geometries. The only inputs are computed tomography angiography (CTA) scans, which are already recorded in clinical routine. We show how integrated model extraction and visualization can help to efficiently detect stenoses and we provide means for automatic, highly accurate stenosis degree computation. We directly connect multiple sophisticated processing stages, including a neural prediction network for lumen and plaque segmentation and automatic global diameter computation. We enable interactive and retrospective user control over the processing stages. Our aims are to increase user trust by making the underlying data validatable on the fly, to decrease adoption costs by minimizing external dependencies, and to optimize scalability by streamlining the data processing. We use interactive visualizations for data inspection and adaption to guide the user through the processing stages. The framework was developed and evaluated in close collaboration with radiologists and neurologists. It has been used to extract and analyze over 100 carotid bifurcation geometries and is built with a modular architecture, available as an extendable open‐source platform.
Memory‐Efficient GPU Volume Path Tracing of AMR Data Using the Dual Mesh
Authors: Zellmann Stefan , Wu Qi , Ma Kwan‐Liu , Wald Ingo 
Published: June 2023

AbstractA common way to render cell‐centric adaptive mesh refinement (AMR) data is to compute the dual mesh and visualize that with a standard unstructured element renderer. While the dual mesh provides a high‐quality interpolator, the memory requirements of the dual meshdata structureare significantly higher than those of the original grid, which prevents rendering very large data sets. We introduce a GPU‐friendly data structure and a clustering algorithm that allow for efficient AMR dual mesh rendering with a competitive memory footprint. Fundamentally, any off‐the‐shelf unstructured element renderer running on GPUs could be extended to support our data structure just by adding agridletelement type in addition to the standard tetrahedra, pyramids, wedges, and hexahedra supported by default. We integrated the data structure into a volumetric path tracer to compare it to various state‐of‐the‐art unstructured element sampling methods. We show that our data structure easily competes with these methods in terms of rendering performance, but is much more memory‐efficient.
Don't Peek at My Chart: Privacy‐preserving Visualization for Mobile Devices
Authors: Zhang Songheng , Ma Dong , Wang Yong 
Published: June 2023

AbstractData visualizations have been widely used on mobile devices like smartphones for various tasks (e.g., visualizing personal health and financial data), making it convenient for people to view such data anytime and anywhere. However, others nearby can also easily peek at the visualizations, resulting in personal data disclosure. In this paper, we propose a perception‐driven approach to transform mobile data visualizations into privacy‐preserving ones. Specifically, based on human visual perception, we develop a masking scheme to adjust the spatial frequency and luminance contrast of colored visualizations. The resulting visualization retains its original information in close proximity but reduces visibility when viewed from a certain distance or farther away. We conducted two user studies to inform the design of our approach (N=16) and systematically evaluate its performance (N=18), respectively. The results demonstrate the effectiveness of our approach in terms of privacy preservation for mobile data visualizations.
Illustrative Motion Smoothing for Attention Guidance in Dynamic Visualizations
Authors: Eschner Johannes , Mindek Peter , Waldner Manuela 
Published: June 2023

Abstract3D animations are an effective method to learn about complex dynamic phenomena, such as mesoscale biological processes. The animators' goals are to convey a sense of the scene's overall complexity while, at the same time, visually guiding the user through a story of subsequent events embedded in the chaotic environment. Animators use a variety of visual emphasis techniques to guide the observers' attention through the story, such as highlighting, halos – or by manipulating motion parameters of the scene. In this paper, we investigate the effect of smoothing the motion of contextual scene elements to attract attention to focus elements of the story exhibiting high‐frequency motion. We conducted a crowdsourced study with 108 participants observing short animations with two illustrative motion smoothing strategies: geometric smoothing through noise reduction of contextual motion trajectories and visual smoothing through motion blur of context items. We investigated the observers' ability to follow the story as well as the effect of the techniques on speed perception in a molecular scene. Our results show that moderate motion blur significantly improves users' ability to follow the story. Geometric motion smoothing is less effective but increases the visual appeal of the animation. However, both techniques also slow down the perceived speed of the animation. We discuss the implications of these results and derive design guidelines for animators of complex dynamic visualizations.
