RETRACTED: The risk evaluation and management of the sports service supply chain by introducing fuzzy comprehensive appraisal and artificial intelligence technology
Authors: Teng Ye , Wang Yuxuan , You Huan 
Published: March 2023

AbstractThis article aims to improve the inefficiency of the sports service supply chain (SC) caused by the unscientific management of stakeholders in the sports service SC. First, combined with the literature, the identification and management of the service SC domestically and internationally are explained, providing a meaningful reference for improving sports service bases. Second, fuzzy comprehensive appraisal (FCA) algorithm process and artificial intelligence (AI) technology are used to evaluate and manage the risk of sports service SC. The FCA algorithm provides a comprehensive evaluation factor set for the sports service SC risk evaluation. Then, the complete evaluation set is established. To obtain the evaluation matrix, the ‘expert’ carries out fuzzy evaluation on each single factor. AI provides a data analysis platform for integrated SC risk management. The platform can realize the logical hierarchical relationship between indicators and rules, systematically standardize the sports service SC and rules, and conduct unified display, monitoring, and trend analysis. Finally, the FCA method is used to evaluate the risks of the sports service SC, and the results of the comprehensive management of the dangers of the SC are analysed. The results show that the evaluation indicators of sports service venues' SC service capabilities have a good consistency. The highest weight score of government service capability in the sports service SC is 0.2413, and the lowest weight score of the service capability index of the sports operation platform is 0.1708. Sports service venues' SC capacity in NANCHANG City is relatively average. This article deeply understands the structure of the sports service SC. It provides relevant basis and guidance for sports service integrators, service providers, and other market entities to adjust management strategies and improve market competitiveness. It also clarifies the risks and management results of the sports service SC, provides academic help for the researchers and enriches and develops the theory of the reform and construction of the Chinese sports service SC.

Authors: Seleq Samir , Weilert Frank , Fulforth James 
Published: March 2023

AbstractBackground and AimsInflammatory bowel disease (IBD) prevalence is rising globally; however, indigenous groups are underrepresented. Waikato, New Zealand, is a large region with a high proportion of Māori patients. In Canterbury in 2006, 1% of patients with IBD were Māori. We investigated the incidence and prevalence of IBD in Waikato over 10 years.MethodsThis was a retrospective cohort study assessing the incidence and prevalence of IBD between 2009 and 2019. The search strategy included pathology, radiology, Provation, ICD‐10 coding and private clinics, using the keywords: Crohn's, Crohn, ileitis, colitis, ulcerative, inflammatory bowel disease and IBD. Collected data included current age and age at diagnosis, sex, ethnicity and IBD subtype.ResultsThe IBD point prevalence on 31 December 2019 was 375.6/100 000 compared with 293.6/100 000 in 2010, increasing by 27.9%. The annualised incidence was static from 21.5/100 000 in 2010 to 17.5/100 000 in 2019. Female patients comprised 53.3% of the cohort. Ulcerative colitis (UC) made up 54.2% of cases, 43.8% had Crohn disease (CD) and 2.0% had indeterminate colitis. Sixty (3.7%) patients identified as Māori. In non‐Māori patients, the average age at diagnosis was 36.2 years, compared with 33.0 years in Māori patients (P = 0.11). In Māori patients, 53.3% had UC and 45.0% had CD. Thirty‐five percent of Māori patients lived 50 km or more from base hospital, compared with 41% of non‐Māori patients (P = 0.33).ConclusionIBD prevalence has increased substantially; however, the incidence has remained static. Māori IBD rates are higher than previously reported, in keeping with international indigenous trends. Māori patients were diagnosed at a similar age as non‐Māori patients, with similar disease subtypes.
Analysis of pre‐hospital delay in Chinese patients with diabetic foot ulcers: Based on 46 cases

Published: March 2023

AbstractTo study the causes of pre‐hospital delay in Chinese patients with diabetic foot ulcers (DFUs). A retrospective study, investigating a case series of 46 DFUs treated at a single hospital, was conducted to evaluate wound condition, wound treatment, costs, and patients' complete medical records, and analyse the reasons causing the pre‐hospital delay. We assessed 46 DFUs aged between 53 and 92 years old. The average pre‐hospital delay was 5 months, with nearly 20% being delayed for more than 1 year. The average length of hospital stay in China was 21 days, with an average cost of $8672. Recurrence rate of DFUs was 21%, and three patients were recommended to transfer to upper‐level hospital. Besides, the intervention was limited and homogenous and medical records were incomplete. Medical service users' limited understanding of diseases, high costs that patients need to afford, and unsatisfactory treatment by medical service providers are the main reasons for patients' delay in seeking treatment. Recommendations are offered to reduce the pre‐hospital delay of Chinese patients with DFUs.
Not every high‐latitude or high‐elevation forest edge is a treeline
Authors: Körner Christian , Hoch Günter 
Published: March 2023

AbstractAttempts at identifying climate warming effects on mountain and arctic vegetation caused a recent hype in treeline studies. In this perspectives article, we recall the need of clear‐cut definitions, a consistent terminology and a theoretical framework that permits hypothesis testing. Founded in the ecological niche concept, the application of the fundamental niche edge to treeline permits defining the potential climatic limit of tree growth, while the realized niche edge captures all deviations for reasons related to other, more local, abiotic factors, biotic interactions, disturbances and human interventions. An important point is that a globally common phenomenon calls for a common abiotic driver which is the temperature at the low temperature edge of the niche of the life form tree. We explain why other abiotic factors that may affect the local range limits, such as microclimate, moisture and wind do not devaluate the classical isotherm concept. Our key message is that applying a clearly defined concept of potential treeline, also allows defining deviations from it and explaining the deviations within a reproducible theoretical framework.

The optical waveguide excitation fluorescence microscopy structure is systematically and comprehensively analysed at the wavelengths of 488, 532 and 646 nm for fluorescent dyes. The analysis results provide some useful suggestions, which will be beneficial to the research of an optical waveguide evanescent field fluorescence microscopy.
Healthy and Equitable Interpersonal Relationships, Health Inequalities and Socio‐Educational Interventions: A Conceptual Framework for Action
Authors: Forcadell‐Díez Lluís , Juárez Martínez Olga , Abiétar Daniel G. , López María José , Sánchez‐Martínez Francesca , Perez Gloria 
Published: March 2023

ABSTRACTBACKGROUNDInterpersonal relationships undoubtedly have a bidirectional connection with the health of individuals and communities. Relational models based on equity contribute to well‐being, while asymmetrical relationships based on hierarchies and differences of power negatively impact mental, physical, and social health.METHODSA conceptual framework for understanding the determinants of interpersonal relational models was developed.RESULTSStructural determinants were identified as the combined action of systems of oppression, the socio‐historical context that normalizes violence, and social stratification and segregation, consequences which included inequitable access to power, resources, and opportunities. Intermediate determinants include individual, psychosocial, behavioral, and community aspects. Structural and intermediate determinants impact health and health inequalities through multiple relational patterns that are simultaneously established and sustained by individuals and communities. The health impact of inequitable relational patterns includes: Reduced self‐esteem; anxiety, stress, and depression; acceptance of violence; physical and sexual harm; suicide; and murder.CONCLUSIONSThis conceptual framework allows for the modification of relational models by influencing structural and intermediate determinants. Six areas of intervention have been identified: educative policies, school governance, physical and symbolic space, school curriculum, school‐community relations, and socio‐educative interventions to promote healthy and equitable relationships. Healthy and equitable relationships are associated with improved subjective well‐being, health status and protection from violence. Socio‐educational interventions that consider the elements of this conceptual framework may be effective in promoting healthy and equitable relational models.
Different settings, different terms and conditions: The impact of intellectual property arrangements on co‐creation project performance
Authors: Tekic Anja , Willoughby Kelvin W. , Füller Johann 
Published: March 2023

AbstractInnovation‐focused co‐creation between companies and individual external contributors is accompanied by the challenge of managing intellectual property (IP). The existing literature presents scattered evidence of various elements of the arrangements adopted by companies to manage their IP (such as a high or low degree of IP control, monetary or non‐monetary compensation, non‐disclosure agreements, additional agreements, and the waiver option) in different co‐creation settings (including crowdsourcing contests, virtual communities, single expert sessions, and lead user workshops). However, the existing literature exhibits little understanding of how particular IP arrangements influence co‐creation project performance in specific settings. Drawing upon contingency theory and configurational theory, we provide a framework that explains both the effectiveness of different IP configurations and the moderating role that co‐creation settings may have on the relationship between IP arrangements and project performance. By the means of fuzzy‐set Qualitative Comparative Analysis (fsQCA) on a sample of 116 co‐creation projects, we determine the impact of various IP arrangements on project performance in different co‐creation settings, and we show how this effect differs across those settings. Our study also demonstrates that IP matters for success in co‐creation, while highlighting the interdependence of multiple elements of IP arrangements and their joint influence on co‐creation project performance. Our study thus fills the gap in the literature where previous research failed to embrace the context‐dependent and multidimensional effect of IP arrangements on co‐creation project performance. Additionally, this study offers best‐practice guidelines for managers for designing IP arrangements to meet the specific characteristics of their co‐creation projects and to ensure their success.
COVID‐19 and Childlessness among Women in the United States
Authors: Hummer Holly 
Published: March 2023

AbstractThe COVID‐19 pandemic has prompted questions about individuals’ fertility intentions and decisions during such a large‐scale, drawn‐out crisis. In this paper, I ask how women who have not (yet) had children and who are nearing the end of their timeline for parenthood are making sense of the pandemic. Drawing on novel in‐depth interview data conducted during the pandemic with over 100 women aged 35–50 in the United States who are childless for a variety of reasons, I argue that the pandemic has produced a shared sense of “gendered uncertainty” by exacerbating both preexisting worries about motherhood and unease about the future. As the data further reveal, the pandemic has therefore been conceived of by many childless women as a good time to not have children, particularly in light of the United States’ weak infrastructure of family support. These findings contribute to existing theoretical frameworks of fertility change by foregrounding women's subjective evaluations of their reproductive options during a time of upheaval and introducing the important role of gendered uncertainty in shaping reproductive sense‐making. Findings also contribute to the literature on childlessness by demonstrating how childlessness can gain newfound appeal as a family status during turbulent times.

AbstractCassava production in Ivory Coast is hampered by cassava mosaic disease (CMD), which is caused by several begomovirus species. To increase cassava production and conserve genetic resources, the Centre National de Recherche Agronomique (CNRA) maintains a germplasm collection of 610 cassava accessions of various origins, which is kept in open fields in Bouaké and Man. We carried out an epidemiological assessment of the collection and a molecular characterization of the viruses infecting the CNRA cassava germplasm. The field in Man was less affected by CMD (incidence 49.78%, severity 2.23, whitefly infection 2.23%), despite the abundant whitefly populations (1.34 per plant), compared to Bouaké (incidence 74.54%, severity 2.92, whitefly infection 8.04% and whitefly population of 0.34 per plant). However, the predominant mode of CMD transmission was through infected cassava cuttings at both sites. PCR analysis showed that the East African cassava mosaic Cameroon virus (EACMCMV) was always found in co‐infection with African cassava mosaic virus (ACMV), which also occurred in single infection. Co‐infections of EACMCMV and ACMV were more prevalent in Bouaké (52.64%) than Man (13.87%). Eleven complete genome sequences of cassava mosaic begomoviruses infecting the CNRA germplasm were obtained, and phylogenetic analysis showed that they are closely related to ACMV and EACMCMV isolates from Ghana, Burkina Faso and Nigeria. The results of this study will assist breeders to screen accurately for CMD resistance in progeny resulting from parental lines, enabling the strategic distribution of new clean cassava planting materials to reduce the impact of CMD.
Maternal activism in comparative perspective: Past, present, and future
Authors: Mendoza Elva F. Orozco 
Published: March 2023

AbstractThis essay offers a comparative assessment of past and present contributions to the study of maternal activism within feminist scholarship broadly understood while also providing some thoughts about its future directions. While typically defined as adopting a maternal frame to pursue a social or political cause, this essay posits maternal activism as an evolving and contested field of inquiry. I start this analysis by discussing early critiques of motherhood as a patriarchal institution within liberal feminism and other competing frameworks that conceive maternalism as a distinct modality of thought and action. I then underscore the evolving character of the field by examining scholarly works on Black, Indigenous, and Latin American maternal activism. Building upon past and present analyses, and in line with their evolving character, I formulate a provisional definition of maternal activism as a caretaking function sustained through direct action inside and outside the household and beyond that activist‐scholars interested in exploring future directions of maternal activism can engage and re‐envision. This essay contributes to existing analyses by highlighting the transformative character of maternal activism scholarship.

Authors: Kim Cheonsoo 
Published: March 2023

AbstractObjective: This study investigated the utilization of social media during the 2020 South Korean general election, which took place during the COVID‐19 pandemic, using the equalization versus normalization framework.Methods: This study estimated the associations between the characteristics of candidates and their respective constituencies and the use of various social media platforms by the candidates.Results: Dominant political actors were more active social media users, supporting the normalization hypothesis. However, when considering the candidates’ chances of winning the election, social media's normalizing effect was weakened.Conclusion: This study provides new insights into the equalization versus normalization debate by analyzing social media use in a context where offline campaigning was restricted.
Opening up New Geographical Ontologies around Adapting to Climate Change
Authors: Fisher Susannah 
Published: March 2023

AbstractOpening up regional ontologies for climate action is a necessary and underexplored dimension of climate change policymaking. This commentary explores how a regional lens might be integrated into the complex mosaic of climate governance, particularly in the context of resilient regions. I argue regional ontologies for climate policymaking could have greater analytical power if integrated into a theoretical framing of action that goes beyond the nation‐state, beyond formal policy processes and beyond a strict binary between science and policy. Applying this lens to resilient regions, I argue there are particular opportunities at the regional scale for highlighting diverse perspectives or adaptation issues obscured through a national ontology, using existing transnational data infrastructure and community‐led data systems to support the regional ontology and reframing the scale of collective future visions for a climate‐adapted world.
Learning How to Make Decisions in a Nonprofit Sport Organization: An Application of Strategic Decision-Making Theory
Authors: Lachance Erik L. 
Published: March 2023

This teaching-based case study tasks students with analyzing a strategic decision. This analysis is guided by a script describing a strategic decision undertaken in a fictional nonprofit sport organization (i.e., Canadian Ice Tennis Federation). Students’ analysis is achieved by applying strategic decision-making theory, including its five central constructs: centrality, duration, flow, interaction, and scrutiny. Knowledge is gained by analyzing a strategic decision according to its level of authorization, length, delays, negotiations, and information sources. This teaching-based case study is intended for undergraduate students in general sport management and/or strategy/strategic management courses. The benefit of this teaching-based case study resides in its ability to teach students how to make decisions, a central and ubiquitous task in organizational life, and their future endeavors in the sport industry.
Unconventional Fractional Quantum Hall States in a Wide Quantum Well

Published: March 2023

A bilayer electron system that is formed in a 60-nm-wide GaAs quantum well and has a large difference of the electron densities in the layers has been studied. It has been found that, when a magnetic field is tilted from the normal to the plane of the system, integer quantum Hall effect states at the filling factors of Landau levels of 1 and 2 disappear; instead, fractional quantum Hall effect states in the interval between these filling factors appear at the filling factors νF = 4/3, 10/7, and 6/5 with odd denominators and at the filling factor νF = 5/4. Several different states can be observed under the variation of the magnetic field. The detected fractional quantum Hall effect states are interpreted as combined states with the same filling factor 1 in the layer with the higher density and with the filling factors νF – 1 in the layer with the lower density. These states are formed because of the redistribution of electrons between the layers, which occurs under the variation of the magnetic field. The appearance of the state with the filling factor νF = 5/4 with the even denominator is presumably attributed to the dominance of the interlayer electron–electron interaction over the intralayer one for electrons in the layer with the lower density.

Published: March 2023

Pheochromocytomas are uncommon tumours that originate in chromaffin cells. They are a representation of 0.1%–1% of all cases of secondary hypertension. Most pheochromocytomas are unilateral and benign, featuring catecholamine production, as well as the production of other neuropeptides. Pheochromocytomas are mostly located in the adrenal gland; the frequency of occurrence is highest between 30 and 50 years of age; however, up to 25% of cases may be linked to multiple endocrine neoplasia type 2, Von-Hippel-Landau disease and type 1 neurofibromatosis in the young.We present a case of ruptured left adrenal pheochromocytoma with an atypical presentation. A 30-year-old male patient presented with severe left flank pain and hypertension. The CT scan of the abdomen showed bleeding from the left adrenal mass, where resuscitation and angioembolisation were done. Embolisation of the inferior and superior arteries was done, but the middle failed. The patient experienced a significant drop in haemoglobin and a haemorrhagic shock post angioembolisation, which called for emergency laparotomy. The patient is currently doing well with an uneventful postoperative course.
