Published: April 2023

Purpose
Smart urban governance research has progressed over the past few decades following changes and increasingly complicated city management difficulties. Therefore, the purpose of this paper is to use a scoping review and bibliometric analysis to examine all the publications on smart urban governance, especially in Asia.

Design/methodology/approach
A total of 1,900 smart urban governance articles indexed in the Scopus database was analyzed through scoping review and bibliometric analysis. The articles were analyzed by the number of publications per year, contributing countries, subject areas, authors, cited documents, related issues and cited papers. Furthermore, VOSviewer was used to provide a visual analysis of the co-occurrence of keywords.

Findings
This study indicated that urban smart governance publications continue to increase yearly. Even though the area of analysis is Asia, the USA and China seriously contributed to the analysis. Therefore, the topic of smart urban governance has become a discussion for scholars in the international. From the Scopus database analysis, the top three subject areas are social sciences (28%), environmental science (20%) and medicine (16%). The synthesis using bibliometric analysis by VOSviewer obtained 13 clusters.

Research limitations/implications
This study only focuses on the Scopus database and one specific topic, using one bibliometric analysis tool. Meanwhile, national and international index databases are not used.

Originality/value
This paper examined publication trends on smart urban governance. This paper provided a comprehensive analysis of topic-specific knowledge areas based on previous studies. Additionally, this paper suggested the direction of the development of smart urban governance in the future.

Authors: Thanh Bui Thi , Tran Lobel Trong Thuy 
Published: April 2023

PurposeThis article explores the complementarity between leader encouragement of creativity and knowledge-sharing among peers in enhancing employee creativity in the hotel context. The authors further examine the role of absorptive capability in setting a contextual condition under which creativity affects employee performance.Design/methodology/approachA web-based survey and face-to-face interviews were a means of two-round data collection while using a partial least squares technique for model estimation.FindingsAn analysis of 277 employees showed that leader encouragement and knowledge-sharing are important for creativity to drive performance. At high levels of absorptive capacity, employee performance increases rapidly as creativity increases.Research limitations/implicationsThis article extends how the complementarity between leader encouragement and knowledge-sharing plays an important role in explaining employee creativity and performance under the boundary condition of absorptive capacity.Practical implicationsOrganizational managers could embrace a future creativity–performance strategy by developing absorptive capacity with reward systems to optimize employee performance.Originality/valueThis article substantiates the role of leader encouragement and knowledge-sharing in enhancing the relationship between employee creativity and performance. The strength of this relationship is dependent on the positive moderation of absorptive capacity.

Published: April 2023

PurposeThis research aimed to analyze and prioritize the factors affecting sustainable marketing (SM) and sustainable operation (SO) of manufacturing small and medium-sized enterprises SMEs through big data adoption (BDA).Design/methodology/approachThe technology-organization-environment (TOE) framework was used as a theoretical base and data were gathered from manufacturing SMEs in Malaysia. The 159 questionnaire replies of chief executive officer (CEO)/managers were analyzed using a hybrid approach of structural equation modeling-artificial neural network (SEM-ANN).FindingsThe findings of this study showed that perceived benefits (PB), technological complexity (TC), organization's resources (OR), organization's management support (OMS) and government legislation (GL) are the factors that influence BDA and promote SM and SO. The findings of ANN showed that a perceived benefit is the most important factor, followed by OMS.Practical implicationsThe findings of this study can assist SMEs managers in making strategic decisions and improving sustainable performance and thus contribute to overall economic development.Originality/valueThe manufacturing industry is under immense pressure to integrate sustainable practices for long-term success. BDA can assist industries in aligning industries' operational capabilities. The majority of the current research have mainly emphasized on BDA in corporations. However, the associations between BDA and sustainable performance of manufacturing SMEs have been less explored. To address this issue, this study developed a theoretical model and examined the influence of BDA on SM and SO of manufacturing SMEs. Meanwhile, the hybrid methodological approach can help to uncover both linear and non-linear relationships better.

AbstractObjectiveTo assess whether coronavirus disease 2019 (COVID‐19) vaccination impacts menstrual bleeding quantity.DesignRetrospective cohort.SettingFive global regions.PopulationVaccinated and unvaccinated individuals with regular menstrual cycles using the digital fertility‐awareness application Natural Cycles°.MethodsWe used prospectively collected menstrual cycle data, multivariable longitudinal Poisson generalised estimating equation (GEE) models and multivariable multinomial logistic regression models to calculate the adjusted difference between vaccination groups. All regression models were adjusted for confounding factors.Main outcome measuresThe mean number of heavy bleeding days (fewer, no change or more) and changes in bleeding quantity (less, no change or more) at three time points (first dose, second dose and post‐exposure menses).ResultsWe included 9555 individuals (7401 vaccinated and 2154 unvaccinated). About two‐thirds of individuals reported no change in the number of heavy bleeding days, regardless of vaccination status. After adjusting for confounding factors, there were no significant differences in the number of heavy bleeding days by vaccination status. A larger proportion of vaccinated individuals experienced an increase in total bleeding quantity (34.5% unvaccinated, 38.4% vaccinated; adjusted difference 4.0%, 99.2% CI 0.7%–7.2%). This translates to an estimated 40 additional people per 1000 individuals with normal menstrual cycles who experience a greater total bleeding quantity following the first vaccine dose' suffice. Differences resolved in the cycle post‐exposure.ConclusionsA small increase in the probability of greater total bleeding quantity occurred following the first COVID‐19 vaccine dose, which resolved in the cycle after the post‐vaccination cycle. The total number of heavy bleeding days did not differ by vaccination status. Our findings can reassure the public that any changes are small and transient.

Published: April 2023

AbstractObjectivesTo quantify physical activity in patients prior to and during an acute general medical hospital admission and explore relationships between mobility, pre‐ and in‐hospital physical activity.MethodsThis was a prospective, single‐site secondary observational study conducted on general medical wards at a tertiary hospital. Prehospital physical activity was measured via the Physical Activity Scale for the Elderly (PASE; scored 0–400); in‐hospital physical activity was measured via accelerometry (time at metabolic equivalents [METs] > 1.5), and mobility was measured via the de Morton Mobility Index (DEMMI). Associations were determined via Spearman's correlations.ResultsForty‐six participants were included: median age 81 [76–85] years, 59% female, DEMMI on admission 39 [30–49]. Prehospital physical activity was low (PASE median 27.1 [1.6–61.9]). In‐hospital physical activity was also low (0.5 [0.2–1.5] hours per day being physically active and 54 [16–194] steps per day taken). No statistically significant relationships existed between pre‐ and in‐hospital physical activity (Spearman's rho (ρ) 0.24, 95% CI −0.08–0.53, p = 0.07). However, physical activity levels in the pre‐ and in‐hospital settings were positively associated with patients' mobility in‐hospital (Spearman's ρ 0.44, 95% CI 0.15–0.67, p = 0.002; Spearman's ρ 0.40, 95% CI 0.08–0.645, p = 0.011 respectively).ConclusionsPhysical activity is low both before and during a general medical admission. Assessment of usual physical activity patterns should be part of the clinical assessment of patients in general medicine; however, the low activity levels observed indicate a need for valid and reliable tools suitable for an older, frail cohort. Findings will inform the development of physical activity guidelines during hospitalisation.

Published: April 2023

AbstractObjectivesIntrinsic apoptosis, which is regulated by Bcl‐2 family proteins, has an important role in chronic inflammatory diseases. The aim of the study was to identify the tissue levels and ratios of anti‐ and pro‐apoptotic Bcl‐2 family proteins in peri‐implant diseases.Materials and MethodsTwenty‐three individuals with peri‐implant mucositis, 25 individuals with peri‐implantitis, and 24 controls were included. The following clinical parameters were recorded: keratinized mucosa width, modified bleeding index, probing depth, modified plaque index, modified gingival index, and keratinized tissue thickness. Marginal alveolar bone assessments were performed by a software program. Granulation tissues were collected during treatments of peri‐implant diseases. The control tissue samples were collected during the second stage of implant surgery. The tissue levels of Bcl‐2 family pro‐apoptotic (Bak, Bax, active caspase‐3) and anti‐apoptotic (Bcl‐2, Bcl‐xL, Mcl‐1) proteins were determined by multiplex immunoassay method.ResultsThe pro‐apoptotic proteins; Bak, Bax and anti‐apoptotic proteins Bcl‐2, Bcl‐xL, Mcl‐1 were detected significantly higher in controls compared with patients with peri‐implant mucositis and peri‐implantitis (p < .001), respectively. The higher active caspase‐3 levels were also detected in controls in comparison with peri‐implant mucositis (p = .018) and peri‐implantitis (p = .005). Anti‐apoptotic: pro‐apoptotic protein ratios (Bcl‐2:Bax, p < .001; Bcl‐2:Bak, p = .01; Bcl‐xL: Bax, p = .006, Bcl‐xL:Bak, p = .011; Mcl‐1:Bak, p < .001) were significantly increased in diseased groups. A positive correlation was demonstrated between clinical variables and anti‐apoptotic: pro‐apoptotic ratios.ConclusionOur findings indicate dysregulation of the Bcl‐2 family proteins in peri‐implant diseases. This unregulated response may disturb the homeostasis of peri‐implant tissue.

AbstractAimsTANK‐binding kinase 1 (TBK1) is involved in regulating the pathological process of a variety of inflammatory diseases in the central nervous system. However, its role and underlying molecular mechanisms in spinal cord injury (SCI) remain largely unknown.MethodsWe employed the TBK1 inhibitor amlexanox (ALX) to address this question. An in vivo clip‐compressive SCI model and in vitro lipopolysaccharide (LPS)‐induced astrocyte inflammation model were established to examine the effects of TBK1 inhibition on the expression of proinflammatory cytokines.ResultsIn this study, we found that TBK1 and TBK1‐medicated innate immune pathways, such as TBK1/IRF3 and noncanonical NF‐κB signaling, were activated in astrocytes and neurons after SCI. Furthermore, inhibition of TBK1 by ALX alleviated neuroinflammation response, reduced the loss of motor neurons, and improved the functional recovery after SCI. Mechanistically, inhibition of TBK1 activity promoted the activation of the noncanonical NF‐κB signaling pathway and inhibited p‐IRF3 activity in LPS‐induced astrocytes, and the TBK1 activity was required for astrocytic activation through yes‐associated protein (YAP) signaling after SCI and in LPS‐induced astrocytes inflammation model.ConclusionTBK1‐medicated innate immune pathway in astrocytes through YAP signaling plays an important role in the pathogenesis of SCI and inhibition of TBK1 may be a potential therapeutic drug for SCI.

Published: April 2023

AbstractAimsTo compare different patterns of memory impairment in patients with two subtypes of mesial temporal lobe epilepsy (MTLE) and healthy controls.MethodsThirty‐five healthy controls and 41 patients with MTLE were recruited, of which 25 patients were diagnosed as hippocampal sclerosis (HS‐MTLE), and the rest 16 patients were lesion‐negative (MRI‐neg MTLE). Participants completed the Wechsler memory assessment and a short‐term memory game on an automated computer‐based memory assessment platform with an eye tracker.ResultsBoth the MRI‐neg MTLE and HS‐MTLE groups took longer time to complete the short‐term memory game than healthy controls (p < 0.001, Cohen's d = 1.087; p = 0.047, Cohen's d = 0.787). During the memory encoding phase, the MRI‐neg MTLE group spent significantly shorter time than healthy controls on the difficult levels with three (p = 0.004, Cohen's d = 0.993) and four targets (p = 0.016, Cohen's d = 0.858). During the memory decoding phase, the HS‐MTLE group spent less time looking on the targets compared to controls when recalling and finding four targets (p = 0.004, Cohen's d = −0.793), while the MRI‐neg MTLE group spent significantly longer time on the distractors and shorter time on the region of interests (ROIs) for all difficulty levels (all p < 0.05) than controls. Furthermore, the eye tracking data were correlated with the scores of the Wechsler Memory Scale after Bonferroni correction (p < 0.05).ConclusionPatients with MRI‐neg MTLE demonstrate impaired memory mostly due to attention deficits, while those with HS‐MTLE show memory impairment with relative sparing of attention. Eye tracking technology has the potential of facilitating the investigation of the mechanism of memory defect in MTLE and can serve as a supplementary neuropsychological tool for clinical diagnosis and long‐term monitoring.

AbstractBackgroundMounting studies have demonstrated that coffee consumption significantly reduces the risk of developing Parkinson's disease (PD). However, there have been few investigations about the role of chronic coffee consumption in nigrostriatal structural neurodegeneration in PD. We aimed to investigate whether chronic coffee consumption is associated with the change in striatal volume in PD.MethodsIn this study, 130 de novo patients with PD and 69 healthy controls were enrolled from the Parkinson's Progression Markers Initiative cohort. Patients with PD and healthy controls were, respectively, divided into three subgroups, including current, ever, and never coffee consumers. Then, striatal volume was compared across the three subgroups. Correlation analyses were performed to assess the relationship between cups consumed per day and striatal volume. Furthermore, we included the factors that may have influenced nigrostriatal dopaminergic neurons in multiple linear regression analyses to identify significant contributing factors to striatal volume in each investigated striatal region.ResultsCurrent coffee consumers had decreased striatal volume compared with ever consumers in controls but not patients with PD. Furthermore, the correlation analyses revealed that cups per day were negatively correlated with striatal volume in current consumers of patients with PD and controls. In addition, multiple linear regression analyses showed that current coffee consumption remained as an independent predictor of a decrease in striatal volume in controls.ConclusionsOur study showed that chronic coffee consumption was negatively correlated with striatal volume. In addition, our study showed that chronic coffee consumption was associated with the change in striatal volume in current—rather than ever coffee consumers, which suggests that the chronic effects of caffeine on striatal morphology may fade and even compensate after quitting coffee. Our study provides evidence for the effect of chronic coffee consumption on striatal volume in human brain in vivo.
Impacts of Market‐based Environmental Regulation on Green Total Factor Energy Efficiency in China
Authors: Li Ge , Gao Da , Li Yi 
Published: April 2023

AbstractThis study employed a difference‐in‐differences design to assess the effect of market‐based environmental regulation on green total factor energy efficiency (GTFEE) in a quasi‐natural experiment that investigated China's carbon emissions trading scheme (ETS). The empirical results show that ETS had a positive effect on GTFEE. A series of robustness tests revealed that the results were robust. Potential mechanisms through which ETS can improve GTFEE include the promotion of technological innovation and the upgrading of industrial structure. The positive effects varied in different cities and different regions – the result was pronounced in eastern China and developed cities, but it was insignificant in central and western areas and developing cities. This study confirms the satisfactory performance of China's ETS in improving GTFEE, and this is relevant for other emerging countries.

SummaryBackgroundThe histogenetic origin of atypical fibroxanthoma (AFX) and pleomorphic dermal sarcoma (PDS) has not been definitively elucidated. In addition to a fibroblastic origin, a keratinocytic differentiation is discussed due to strong clinical, histomorphological and molecular genetic similarities with undifferentiated cutaneous squamous cell carcinoma (cSCC).Patients and Methods56 cases (36 AFXs, 8 PDSs, 12 undifferentiated cSCCs) were evaluated for their clinical, histomorphological, and immunohistochemical characteristics. RNA transcriptome analysis was performed on 18 cases (6 AFXs/PDSs, 6 undifferentiated cSCCs, 6 differentiated cSCCs).ResultsClinically, the strong similarities in age, gender and tumor location were confirmed. Without further immunohistochemical staining, histomorphological differentiation between AFX/PDS and undifferentiated cSCC is often impossible. Principal component analysis of the RNA transcriptome analysis showed that AFX/PDS and differentiated cSCC each formed their own cluster, while the undifferentiated cSCCs fall in between these two groups, but without forming a cluster of their own. When examining differentially expressed genes (DEGs), the heat maps showed that there were cases within the undifferentiated cSCC that were more likely to be AFX/PDS than differentiated cSCC based on their expression profile.ConclusionsThe results provide evidence of molecular similarities between AFX/PDS and undifferentiated cSCC and suggest a common histogenetic origin.
