The role of digital technologies in configuring circular ecosystems
Authors: Rossi Lisa Arianna , Srai Jagjit Singh 
Published: September 2024

PurposeThis paper aims to explore the use of digital technologies in enabling circular ecosystems. We apply supply network (SN) configuration theory and a novel resource pooling lens, more typically used in financial systems, to identify inventory pools, information repositories and financial exchange models among network actors.Design/methodology/approachFive in-depth circular SN case studies are examined where digital technologies are extensively deployed to support circularity, each case representing alternative SN configurations. Data collection involved semi-structured interviews to map SN and resource pooling configurations across each circular ecosystem, with cross-case analysis used to identify distinct pooling and digital strategies.FindingsResults suggest three digitally enabled circular ecosystem archetypes and their related governance modalities: consortia-based information pooling for resource recovery, intermediary-enabled material and financial pooling for remanufacturing and platform-driven information, material and financial pooling for resource optimisation.Research limitations/implicationsDrawing on SN configuration and resource pooling literature, we recognise distinct configurational, stakeholder and resource pooling dimensions characterising circular ecosystems. While this research is exploratory and the identified archetypes not exhaustive, the combination of resource pooling and configuration lenses offers new insights on circular ecosystem configurations and the critical role of resource pools and enabling digital technologies.Practical implicationsWe demonstrate the utility of the resource pooling and configuration approach in the design of digitally enabled circular ecosystems. These archetypes provide practitioners and policymakers with alternative design frameworks when considering circular SN transformations.Originality/valueThis paper introduces a resource netting and pooling configuration lens to circular ecosystems, analogous to financial systems, where cyclical flows and stock are critical and enabled through digital technologies.

Published: September 2024

PurposeGiven the growing emphasis on environmental consciousness and sustainability as core principles within most companies, product-service systems are recognized as strategic approaches to achieving sustainability objectives. Consequently, understanding consumer acceptance of these systems is of paramount importance. This study seeks to explore users' perspectives on the barriers that impede the adoption of product-service systems, intending to prioritize these obstacles.Design/methodology/approachThis study utilizes a social media-based approach, specifically analyzing tweets related to Zipcar, an American car rental company that exemplifies a usage-oriented product-service system. The analysis identifies the factors influencing the acceptance of this system. The study utilizes topic modeling and sentiment analysis techniques to analyze the tweets. The opportunity value of each topic is determined, aiding in the identification of topics that require improvement. Furthermore, the interrelation between topics is explored, followed by correlation analysis to assess their significance.FindingsEight topics strongly related to the keywords are identified. Among them, “responsiveness”, “responsibility”, and “trust” hold the highest opportunity values. The findings emphasize the importance of service providers proactively addressing the obstacles that impede consumers' willingness to adopt product-service systems. Prioritization should be given to topics with higher opportunity values.Originality/valueThis research uncovers the primary obstacles to adopting the product-service system by directly considering consumer opinions and providing a prioritized list of these obstacles.
Why premium in freemium: a hedonic shopping motivation model in virtual game retailing
Authors: Hussain Ali , Ting Ding Hooi , Marder Ben 
Published: September 2024

PurposeHedonic shopping is a growing phenomenon designed to enhance gamers’ virtual content shopping experience with increasing economic significance, yet limited attention has been dedicated to this area. Our study explores key hedonic motivations of virtual content shopping and how hedonic shopping value builds trust (trust in virtual content and trust in virtual retailers) that enhances the intention to pay for premium.Design/methodology/approachThis research adopts a mixed-methods approach. Study 1 is qualitative; 19 semi-structured interviews were conducted with virtual game retail platform users. Study 2, based on the literature review and qualitative inquiry findings (obtained from Study 1), proposes a research model empirically validated by analyzing survey data administered to 437 online gamers from gaming zones, cybercafés and e-sports centers.FindingsThe results show that in-game shopping-related adventure-, gratification-, role- and idea-seeking motivations significantly influence gamers' perceived hedonic shopping value. In turn, perceived shopping value has a significant indirect effect through trust on gamers’ intention to pay for premium.Originality/valueThis research contributes to gaming literature by offering a comprehensive model that elucidates the role of hedonic shopping in increasing gamers’ trust, which explains purchase behavior in the virtual game retail context. The findings deepen the understanding of the game retailing landscape and offer strategies to build gamers’ trust, increase premium usage and retain existing spenders.

Authors: Dang Binh Thi Thanh , Yawei Wang , Abdullah Abdul Jabbar 
Published: September 2024

Purpose The study attempts to examine the impact of the US-China trade war on Vietnamese exports to the United States, which has consistently served as a key market for Vietnamese goods and services in recent decades. The heterogeneous effects of the trade war on different export sectors are also evaluated.Design/methodology/approach The secondary data on Vietnamese exports to the US at a 6-digit level is collected from UN Comtrade. Besides, the difference-in-differences (DiD) method is employed to analyze the impact of the trade war on exports from Vietnam to the United States.Findings The findings revealed a 14% increase in total Vietnamese exports to the United States due to the trade war. Examining heterogeneous effects, certain industries, such as plastics, iron or steel articles, textiles and garments, and machinery and mechanical appliances, experience significant benefits. However, the study did not identify statistically significant effects on other sectors, such as electrical machinery products, agricultural and forestry, and furniture.Originality/value The paper is one among limited studies considering the causal effects of the trade war on a developing country, accounting for the heterogeneous effects on different export sectors.
Network embeddedness and mobile inventors' creativity: role of the cognitive dimension
Authors: Wang Zeqian , Wang Chengjun , Sun Xiaoming , Feng Tao 
Published: September 2024

PurposeThe role of inventors' creativity is crucial for technological innovation within enterprises. The mobility of inventors among different enterprises is a primary source for companies to acquire external knowledge. The mechanism of “learning-by-hiring” is widely recognized by companies. Therefore, it is important to determine how to allocate network resources to enhance the creativity of inventors when companies hire mobile inventors.Design/methodology/approachThe study suggests an analytical framework that analyzes alterations in tie strength and structural holes resulting from the network embeddedness of mobile inventors as well as the effect of the interaction between these two variables on changes in inventor’s creativity after the mobility. In addition, this paper examines the moderating impact of cognitive richness of mobile inventors and cognitive distance between mobile inventors and new employers on the correlation between network embeddedness and creativity.FindingsThis study found that: (1) The increase of tie strength has a significant boost in creativity. (2) Increasing structural holes can significantly improve the creativity of mobile inventors. (3) When both the tie strength and the structural holes increase, the creativity of the mobile inventors significantly increases. (4) It is important to note that when there is a greater cognitive distance, stronger tie strength promotes the creativity of mobile inventors. Additionally, cognitive richness plays a significant role in moderating the relationship between changes in structural holes and the creativity of mobile inventors.Originality/valueThese findings provide theoretical guidance for firms to effectively manage mobile inventors and optimize collaborative networks within organizations.

PurposeIn the Global South where humanitarian responses to disasters are often hampered by systemic gaps, community-based humanitarian actors play a crucial but underexplored role in mediating aid to vulnerable populations. This study explores the everydayness of humanitarian action through the lived experiences of urban community leaders during the COVID-19 Pandemic in the Philippines. Specifically, it sheds light on their engagement with national-level responders, the typologies of humanitarian activities they undertook and the contextual factors influencing their decision-making.Design/methodology/approachUsing a qualitative approach, this study presents interviews with 35 community-based humanitarian leaders in urban poor areas of Metro Manila, Philippines. Analytical themes were developed inductively from the transcripts.FindingsDue to mobility restrictions from quarantine protocols, the typologies of humanitarian action shifted to accommodate arising challenges from pandemic management. Engagement with formal humanitarian actors were premised on pre-existing relationships. The study further reveals that, despite lacking formal training, community leaders utilized preexisting networks of care while subscribing to Filipino communal values of bayanihan (working together), malasakit (care) and pagkakaisa (unity). The findings underscore the need for discourse on the realities faced by community leaders and highlight the importance of holistic and gendered capacity building for effective disaster response in vulnerable communities.Originality/valueThis study contributes to understanding the intricate dynamics of humanitarian coordination, particularly in areas where community leaders act as critical intermediaries between their constituents and external support providers and concludes with critical take on localization as a form of community resilience to disaster events.
Warning! This is not your typical mentor training: an invitation to explore a video-based mentor training to prepare mentor teachers for their roles in the classroom
Authors: Silverman Jamie , Pasko Michelle 
Published: September 2024

PurposeThe purpose of this conceptual paper is to define and explore the roles of mentors, the responsibilities and even misconceptions of their position in partnership schools, the characteristics of effective mentors, the gaps that exist in current mentor training and the need for updated and forward-thinking flexible and accessible mentor training as it relates to improvements in University Teacher Preparation Programs and their partnership schools.Design/methodology/approachThe authors detail the process of interviewing a diverse population of mentors and teacher candidates (TCs) who have participated in our professional development (partnership) schools. See Appendices A and B for parallel questions posed during each interview process. Following the interviews, data were gathered in both text and video-based formats to create mentor training video modules to improve the current state of mentor training in our program. Themes were identified following an analysis of both interview intakes, and modules were created to align with these themes.FindingsFollowing the first rounds of implementation, the authors have reflected and noted that a need for an even more diverse population of both mentors and interns to be interviewed is necessary moving forward. The authors do note an appreciation by mentors and university partners in the quality, flexibility and accessibility that this new video module-based mentor training program provides.Practical implicationsThe video-based mentor training modules that the authors detail honor the needs of both new and returning mentors. Via the interviews with teacher candidates, mentors are able to empathize and understand how to be better mentors to their future TCs. Via the scenarios and questions that follow each thematically driven module, mentors are able to independently reflect on their current practices and ways to improve their roles. At any point in the internship year, mentors can return to the video training modules to review and thus improve their practice.Social implicationsMentors, university supervisors, teacher candidates and site coordinators (those individuals who identify mentors in their buildings) note improvement in their ability to communicate effectively as a result of being presented with video modules and reflections about the role of mentors from both mentors and TCs.Originality/valueThe authors were called on by leadership in the College of Education at the University to create this original mentor training video module. It is unique to the College of Education at the University. Great value exists in its accessibility, adaptability (we can upload new videos at any time) and representation of both the mentor and TC perceptions, suggestions and experiences in our program.
Whole‐genome resequencing improves the utility of otoliths as a critical source of DNA for fish stock research and monitoring

Published: September 2024

AbstractFish ear bones, known as otoliths, are often collected in fisheries to assist in management, and are a common sample type in museum and national archives. Beyond their utility for ageing, morphological and trace element analysis, otoliths are a repository of valuable genomic information. Previous work has shown that DNA can be extracted from the trace quantities of tissue remaining on the surface of otoliths, despite the fact that they are often stored dry at room temperature. However, much of this work has used reduced representation sequencing methods in clean lab conditions, to achieve adequate yields of DNA, libraries and ultimately single‐nucleotide polymorphisms (SNPs). Here, we pioneer the use of small‐scale (spike‐in) sequencing to screen contemporary otolith samples prepared in regular molecular biology (in contrast to clean) laboratories for contamination and quality levels, submitting for whole‐genome resequencing only samples above a defined endogenous DNA threshold. Despite the typically low quality and quantity of DNA extracted from otoliths, we are able to produce whole‐genome libraries and ultimately sets of filtered, unlinked and even putatively adaptive SNPs of ample numbers for downstream uses in population, climate and conservation genomics. By comparing with a set of tissue samples from the same species, we are able to highlight the quality and efficacy of otolith samples from DNA extraction and library preparation, to bioinformatic preprocessing and SNP calling. We provide detailed schematics, protocols and scripts of our approach, such that it can be adopted widely by the community, improving the use of otoliths as a source of valuable genomic data.

AbstractObjectiveTo evaluate the association between exposure to atypical antipsychotics during pregnancy and risk of miscarriage.Material and MethodsThis nested case–control study used a large Japanese administrative database. Pregnancy onset and outcomes were estimated using previously reported algorithms, classifying cases as women becoming pregnant between 2013 and 2022 and ending in a miscarriage. Controls were randomly selected from the entire pregnancy cohort by risk‐set sampling with replacement and were individually matched to the cases (3:1). The association between exposure to atypical antipsychotics and risk of miscarriage was assessed using conditional logistic regression adjusted for confounders. The association between benzodiazepine exposure and the risk of miscarriage was assessed as a positive control.ResultsIn the cohort, 44,118 patients were matched with 132,317 controls. The mean ages (standard deviations) of the case and control groups were 33.3 (5.7) and 33.2 (5.5) years, respectively. The prevalence of atypical antipsychotics was 0.5% in both groups. Aripiprazole is an individual antipsychotic with the highest prescription prevalence. The adjusted odds ratios (aOR) for miscarriage were 0.966 (95% confidence interval [CI], 0.796–1.173) for atypical antipsychotics and 0.998 (0.784–1.269) for aripiprazole. A higher aOR (1.431, 95% CI 1.303–1.573) suggested an association with benzodiazepines. A sensitivity analysis that limited the population to women diagnosed with schizophrenia alone did not suggest an association between atypical antipsychotics and the risk of miscarriage.ConclusionsThe results of this study do not suggest an association between exposure to atypical antipsychotics during pregnancy and the risk of miscarriage.
Does economic freedom push people into suicide? New evidence from developing and developed societies, 1980–2019
Authors: Rutar Minea , Rutar Tibor 
Published: September 2024

AbstractThis research paper investigates the impact of market liberalization on country‐level suicide rates using a sample of 96 developing and developed countries from 1980 to 2019. We estimate fixed‐effects panel regression models with robust standard errors clustered at the country level and conduct a variety of robustness checks, including using different estimators and disaggregating the data. We consistently find that the aggregate Economic Freedom of the World (EFW) measure is not statistically significantly related to within‐country variations in age‐standardized suicide rates, but some individual components are. Freedom to trade internationally weakly predicts increases in suicide rates, while sound money is associated with decreased suicide rates. The former result is highly vulnerable to different specifications. This study underscores the existence of a complex, non‐intuitive relationship between market liberalization and suicide rates, suggesting that both critics and defenders of liberalization might be mistaken in making any unequivocal judgments about the process.
Offshore Citizenship: “Diversified Citizenship Portfolios” and the Regulatory Arbitrage of Global Wealth Elites
Authors: Kunz Sarah 
Published: September 2024

AbstractThis paper reads the sale of citizenship via citizenship‐by‐investment (CBI) programmes through an offshore lens. Scholarship on offshore industries has long positioned citizenship sales as part of offshore capitalism—without exploring the phenomenon in any depth. Research on CBI, in turn, has with some notable exceptions neglected the phenomenon's offshore nature. This paper argues that CBI is an outgrowth and increasingly integral part of offshore capitalism, offering a new form of what Susan Roberts calls “regulatory arbitrage”, aiding elite wealth accumulation and power. The paper establishes this relationship by examining the countries and firms selling citizenship, their marketing strategies and customers and, crucially, the nature of the product which rests on the three “offshore pillars”, as described by Ronen Palan—virtual residency, easy incorporation, and secrecy. Conceptualising CBI as an offshore provision can transform how the phenomenon is understood and opens new avenues of thinking about its socio‐structural role and impact in an unequal world.
Otolith‐based species identification in the killifish Aphaniops (Teleostei; Cyprinodontiformes; Aphaniidae) using both morphometry and wavelet analysis
Authors: Charmpila Eleni A. , Teimori Azad , Reichenbacher Bettina 
Published: September 2024

AbstractThe killifish genus Aphaniops consists of nine species distributed in Eastern Africa and the Middle East. However, distinguishing these species from each other based on morphological traits is challenging. Here we investigate the utility of otoliths (sagittae) in distinguishing between A. dispar, A. ginaonis, A. hormuzensis, A. kruppi and A. stoliczkanus. Our approach is based on otoliths from 89 specimens and involves (1) otolith morphometrics, following prior recommendations, (2) shape analysis of otolith contours based on discrete wavelet transformation—a novel method in killifish otolith research—and comparative statistical analyses. Both methods reveal significant interspecific variation in the otolith regions of the rostrum, antirostrum and excisura. While method (1) effectively discriminates most species, method (2) struggles to differentiate A. hormuzensis, A. stoliczkanus and A. kruppi. Additionally, both methods encounter challenges in correctly classifying A. hormuzensis due to the high otolith variability of this species in our sample. Possible factors accounting for their variability are environmental fluctuations at the sampled hot sulphuric spring (Khurgo) and potential introgressive hybridization. We conclude that otolith morphometry is a valuable tool for Aphaniops species identification. Furthermore, we found that the distinctiveness of species‐specific otolith traits increases with the divergence age of the species.
