Research on the generalization of social bot detection from two dimensions: feature extraction and detection approaches
Authors: Zeng Ziming , Li Tingting , Sun Jingjing , Sun Shouqiang , Zhang Yu 
Published: September 2022

PurposeThe proliferation of bots in social networks has profoundly affected the interactions of legitimate users. Detecting and rejecting these unwelcome bots has become part of the collective Internet agenda. Unfortunately, as bot creators use more sophisticated approaches to avoid being discovered, it has become increasingly difficult to distinguish social bots from legitimate users. Therefore, this paper proposes a novel social bot detection mechanism to adapt to new and different kinds of bots.Design/methodology/approachThis paper proposes a research framework to enhance the generalization of social bot detection from two dimensions: feature extraction and detection approaches. First, 36 features are extracted from four views for social bot detection. Then, this paper analyzes the feature contribution in different kinds of social bots, and the features with stronger generalization are proposed. Finally, this paper introduces outlier detection approaches to enhance the ever-changing social bot detection.FindingsThe experimental results show that the more important features can be more effectively generalized to different social bot detection tasks. Compared with the traditional binary-class classifier, the proposed outlier detection approaches can better adapt to the ever-changing social bots with a performance of 89.23 per cent measured using the F1 score.Originality/valueBased on the visual interpretation of the feature contribution, the features with stronger generalization in different detection tasks are found. The outlier detection approaches are first introduced to enhance the detection of ever-changing social bots.
Do subnational performance assessments lead to improved governance? Evidence from a field experiment in Vietnam
Authors: Malesky Edmund , Phan Tuan-Ngoc , Le Anh Quoc 
Published: September 2022

PurposeSingle-party regimes increasingly use Subnational Performance Assessments (SPAs) – rankings of provinces and districts – to improve governance outcomes. SPAs assemble and publicize information on local government performance to facilitate monitoring and generate competition among officials. However, the evidence are sparse on their effects in this context. The authors argue that built-in incentive structures in centralized single-party regimes distort the positive impact of SPAs.Design/methodology/approachThe staggered rollout of the Vietnam Provincial Governance and Public Administration Performance Index (PAPI) created a natural experiment. Due to 2010 budget constraints, the first iteration of the PAPI survey covered only 30 of Vietnam’s 63 provinces before covering all in 2011. The PAPI team used matching procedures to identify a statistical twin for each province before randomly selecting one from each pair. The authors use randomization inference to compare the outcomes of these control and treatment groups in 2011.FindingsExposure to PAPI helped improve almost all aspects of governance; however, significant evidence of prioritization bias exist. The positive effects only persisted for the dimension of administrative procedures, which was the one area of governance that was prioritized by the central government at the time. Other dimensions only registered short-term effects.Originality/valueOur study provides an examination of the impact of SPAs in a single-party regime context. In addition, the authors leverage the natural experiment to identify information effects causally. The authors also look past short-term effects to compare outcomes for five years after the treatment occurred.
Nonlinear effects of bank regulation stringency on bank lending in selected sub-Saharan African countries
Authors: Thamae Retselisitsoe I. , Odhiambo Nicholas M. 
Published: September 2022

PurposeThis paper aims to investigate the nonlinear effects of bank regulation stringency on bank lending in 23 sub-Saharan African (SSA) countries over the period 1997–2017.Design/methodology/approachThis study employs the dynamic panel threshold regression (PTR) model, which addresses endogeneity and heterogeneity problems within a nonlinear framework. It also uses indices of entry barriers, mixing of banking and commerce restrictions, activity restrictions and capital regulatory requirements from the updated databases of the World Bank's Bank Regulation and Supervision Surveys as measures of bank regulation.FindingsThe linearity test results support the existence of nonlinear effects in the relationship between bank lending and entry barriers or capital regulations in the selected SSA economies. The dynamic PTR estimation results reveal that bank lending responds positively when the stringency of entry barriers is below the threshold of 62.8%. However, once the stringency of entry barriers exceeds that threshold level, bank credit reacts negatively and significantly. By contrast, changes in capital regulation stringency do not affect bank lending, either below or above the obtained threshold value of 76.5%.Practical implicationsThese results can help policymakers design bank regulatory measures that will promote the resilience and safety of the banking system but at the same time not bring unintended effects to bank lending.Originality/valueTo the best of the authors’ knowledge, this is the first study to examine the nonlinear effects of bank regulatory measures on bank lending using the dynamic PTR model and SSA context.
Guest editorial: The Triple-A framework for serving humanity with service research
Authors: Kabadayi Sertan , Tsiotsou Rodoula H. 
Published: September 2022

Purpose
This paper aims to propose a conceptual framework for service research and introduces the first ServCollab special issue on the topic “Broadening and reinvigorating the service discipline to reduce human suffering and improve well-being.”

Design/methodology/approach
Building on previous knowledge and personal reflections, the authors developed the “Triple-A framework for serving humanity with service research,” which identifies three crucial features of conducting ethical service research: authentic, advancing and applicable.

Findings
In terms of the research scope, the Triple-A framework proposes that service research should be authentic in its approach, topics of investigation, research questions and theories/frameworks used. Service scholars should close current research gaps using theories, methods, a team of investigators and data that advance service research. Moreover, service research should be applicable by positively impacting society/planet earth, policymakers, organizations and people. Finally, ethical standards should be met in the application of all three features of service research.

Practical implications
Practical guidelines are provided to service researchers for conducting research useful for theory development and practical application.

Social implications
The proposed framework pushes service research to be original, insightful, imaginative, responsible and relevant by seeking to improve individual and society’s well-being.

Originality/value
The authors propose a novel perspective, the “Triple-A framework for serving humanity with service research,” to guide service scholars in conducting state-of-the-art and methodologically rigorous research.

Authors: Garcia Mirella Bezerra , Oliveira Renata Magalhaes , Pitelli Mariusa Momenti , Vieira Jose 
Published: September 2022

PurposeThis paper aims to propose a methodology for managerial decision-making based on scenario planning and a multi-criteria approach.Design/methodology/approachThe methodology consists of two stages, one referring to scenario planning and the other to multi-criteria decision-making. The methodology was applied to a company in the Brazilian agribusiness sector, aiming to help managers face the current situation of the COVID-19 pandemic.FindingsThe proposal addresses a set of simple methods for developing a scenario analysis based on different approaches. Although the methodology may allow the future addition of new, perhaps more robust strategies, the purpose of the analysis is not only to tell the decision maker which strategy should be adopted, but also to provide greater knowledge about the problem and possible scenarios.Originality/valueThe contribution of this research is to propose a structured and easily applicable methodology that can help managers in the future planning of their companies, especially when faced with complex decisions and high level of uncertainty.
Pragmatic deficits in patients with schizophrenia and right hemisphere damage: A pilot study

Published: September 2022

AbstractBackgroundWhile pragmatic deficits are well documented in patients with schizophrenia (SCZ) and right hemisphere damage (RHD), there is a paucity of research comparing the pragmatic deficits of these two groups. Do they experience similar cognitive dysfunction or is there a dissociation between the two patient groups?AimsTo investigate the nature of pragmatic deficits in these two groups and to gain an understanding of the underlying cognitive mechanisms that might be associated with these deficits to further future investigations.Methods & ProceduresA total of 60 participants (15 patients with SCZ; 15 with RHD; 30 (15 + 15) healthy controls (HC) were administered the Bengali Audio‐Visual Test‐Battery for Assessment of Pragmatic Skills.Outcomes & ResultsBoth SCZ and RHD patients were found to have significant pragmatic deficits compared with their matched controls. SCZ patients were found to score significantly better than the RHD group in six out of the 10 pragmatic skills when controlled for age and education. Discriminant function analysis was performed and 86.7% of the cases (HC = 100%, SCZ = 73.3% and RHD = 86.7%) were correctly reclassified into their original categories using the test scores.Conclusions & ImplicationsThe study suggests that there is heterogeneity in the nature of the pragmatic breakdown within and across patient groups. Therefore, individualized restorative measures targeting the disrupted cognitive mechanism(s) might help elevate pragmatic competence and enhance the social functioning of patients with pragmatic deficits.What this paper addsWhat is already known on the subject
Pragmatic deficits are common in adults with cognitive impairments of different etiologies. However, few studies have explored pragmatic deficits across clinical populations. Consequently, very little is known about the nature of pragmatic deficits in patients with schizophrenia and right hemisphere damage.What this paper adds to existing knowledge
This work offers preliminary data on pragmatic difficulties in patients with schizophrenia and right hemisphere damage. This study overrides the boundaries of traditional classifications and evaluates pragmatic difficulties in these two clinical populations with reference to the underlying cognitive mechanisms, which might be disrupted.
What are the potential or actual clinical implications of this work?
The study adds a transdiagnostic perspective suggesting that there might be heterogeneity in pragmatic deficits, both within and across patient groups, and stresses the need for individualized therapy.

AbstractObjectiveTo describe the rates of and risk factors associated with iatrogenic and spontaneous preterm birth and the variation in rates between hospitals.DesignCohort study using electronic health records.SettingEnglish National Health Service.PopulationSingleton births between 1 April 2015 and 31 March 2017.MethodsMultivariable Poisson regression models were used to estimate adjusted risk ratios (adjRR) to measure association with maternal demographic and clinical risk factors.Main outcome measuresPreterm births (<37 weeks of gestation) were defined as iatrogenic or spontaneous according to mode of onset of labour.ResultsOf the births, 6.1% were preterm and of these, 52.8% were iatrogenic. The proportion of preterm births that were iatrogenic increased after 32 weeks. Both sub‐groups were associated with previous preterm birth, extremes of maternal age, socio‐economic deprivation and smoking. Iatrogenic preterm birth was associated with higher body mass index (BMI) (BMI >40 kg/m2 adjRR 1.59, 95% CI 1.50–1.69) and previous caesarean (adjRR 1.88, 95% CI 1.83–1.95). Spontaneous preterm birth was less common in women with a higher BMI (BMI >40 kg/m2 adjRR 0.77, 95% CI 0.70–0.84) and in women with a previous caesarean (adjRR 0.87, 95% CI 0.83–0.90). More variation between NHS hospital trusts was observed in rates of iatrogenic, compared with spontaneous, preterm births.ConclusionsJust over half of all preterm births resulted from iatrogenic intervention. Iatrogenic births have overlapping but different patterns of maternal demographic and clinical risk factors to spontaneous preterm births. Iatrogenic and spontaneous sub‐groups should therefore be measured and monitored separately, as well as in aggregate, to facilitate different prevention strategies. This is feasible using routinely acquired hospital data.

Published: September 2022

AbstractBackgroundThe prognosis of thymic epithelial tumors (TETs) currently relies on the commonly adopted WHO classification and Masaoka staging system, which cannot reflect the undefined biological behaviors limiting them as prognostic factors.MethodsIn this study, we first identified 40 genes and 179 genes, respectively that were epigenetically upregulated and silenced, corresponding to a total of 509 functionally methylated CpG sites between thymomas and thymic carcinomas by using the TCGA dataset.ResultsThe methylation β‐values of cg20068620 in MAPK4 and cg18770944 in USP51 were significantly associated with recurrence‐free survival (RFS). In the independent validation cohort, only WHO classification and methylation β‐values of cg20068620 in MAPK4 were independent prognostic factors for RFS in Chinese patients with TETs. A linear weighted model including these two factors was used to calculate the recurrence risk score (RRS). Time‐dependent ROC curve analysis revealed that RRS was overwhelmingly superior to WHO classification for predicting 3‐, 5‐, and 10‐year RFS and Masaoka stage for 3‐ and 5‐year RFS.ConclusionsThese results suggested that the methylation site cg20068620 in MAPK4 can improve the accuracy of the WHO classification alone regarding the prognostic value of TETs recurrence.
Ecological Imperialism: A Georgist Alternative
Authors: Balce Joffre , Subramaniam Yogeswaran 
Published: September 2022

AbstractEcological imperialism has created property law and economic systems that function to dispossess Indigenous peoples from their traditional lands, territories, and resources. An application of Henry George’s perspectives on economic efficiency and individual liberties suggests that exchanges affecting Indigenous traditional areas are potentially inefficient and unjust if they fail to incorporate Indigenous perspectives of traditional wealth and connections to traditional space. In such circumstances, any loss of traditional lands and resources could be economically inefficient for the Indigenous community concerned, as the land or resource given up may be more valuable than any land or monetary compensation offered. Equally, this loss would deny the liberty of members of the community to associate and determine the use of their lands and resources in accordance with their own priorities. To an extent, this view is harmonious with the current international framework on Indigenous peoples’ rights. Accordingly, participatory legal protections that integrate two perspectives are suggested to prevent unjust exchanges of traditional Indigenous areas and to avoid the contemporary effects of ecological imperialism. Those two perspectives are: i) Georgist conceptions of economic efficiency and individual liberties; and ii) international Indigenous rights standards of free, prior, and informed consent and consultation. Despite the challenges in attaining the universal acceptance and implementation of the alternative represented by these perspectives, its further investigation is nonetheless potentially beneficial.
Mainstream Economics and Conventional Environmental Policies
Authors: Obeng‐Odoom Franklin 
Published: September 2022

ABSTRACTIs mainstream economics only about growth, efficiency, and sustainability? Many critics contend so, but the recent state of the art in economics suggests not. Respectively drawing on reformist neoclassical economics, neoclassical microeconomics “proper,” and behavioral economics, major studies show that mainstream economics provides theories of inequality and unsustainability. However, the theories of causation utilized remain largely neoclassical. Similarly, the bases for repairing the harms are grounded in neoclassical reasoning, while the mechanisms for restoration—ranging from minimalist interventions and income and substitution effects to behavioral nudges—are still mainstream. Fundamentally, they say little or nothing substantial about ecological imperialism, at the heart of which are rent theft and ecological debt, two critical cornerstones of world ecological crises. Therefore, mainstream economists certainly have, use, and apply theories of inequality and unsustainability, but mainstream economists neither have, use, nor apply transformative theories of social stratification, nor ecological imperialism generally. The overall effect of this disconnect from real‐world ecological crises is not simply that conventional environmental policies are incomplete, but that mainstream economics and conventional policies deflect attention from ecological imperialism behind veils of rhetoric, prices, and behaviors.
Adjunctive endoscopic clip marking enhances non‐operative management of massive lower gastrointestinal bleeding
Authors: Hui Jessica Wong Qing , En Joy Wong Qing , Lau Joel , Te Neng Lau , Wong Soong Kuan 
Published: September 2022

AbstractBackgroundsMassive lower gastrointestinal bleeding (LGB) is common especially in elderly patients. Controversy in the approach to management stems from location of bleeding and morbidity of surgery. Colonic diverticula disease (CD) is the leading cause of painless haematochezia and haemodynamic instability.MethodsThe use of a novel technique of endoscopic pre‐marking (EPM) with radiopaque metal clips to localize is described. EPM guided superselective active transarterial embolization (A‐TAE) when active vascular blush was seen. When no active contrast extravasation was seen, EPM also guided prophylactic superselective transarterial embolization (P‐TAE).ResultsFrom May 2004 to December 2021, there were 36 patients with massive LGB from diverticular disease encompassing 44 separate bleeding episodes. Spontaneous haemostasis was observed in 18.2% (8/44). The overall success rate in non‐operative management was 83.3% (30/36) patients. Three patients proceeded for emergency surgery.Of the 36 patients, six patients had documented EPM followed by TAE due to recurrent bleed in the same episode. A‐TAE was performed in two patients. P‐TAE was performed in the four patients without active contrast extravasation. Initial haemostasis was successful in five out of six patients. One patient failed embolization and proceeded to emergency surgery. Three months later, one patient encountered late rebleeding and was scheduled for elective colectomy. None of the six developed intestinal infarction from embolization. The 30‐day mortality was 0%.ConclusionA consistent approach to LGB and defined protocol of endoscopic haemostasis, with routine EPM and embolization, has the potential to mitigate the morbidity and mortality in this group of vulnerable patients.
Incidence of self‐reported pelvic pain and risk factors for pain 1 year after benign hysterectomy: A register study from the Swedish National Quality Registry for Gynecological Surgery

Published: September 2022

AbstractIntroductionThe primary aim of this study was to determine the incidence of patient‐reported pain 1 year after hysterectomy for benign gynecological conditions in relation to occurrence of preoperative pain. The secondary aim was to analyze clinical risk factors for pain 1 year after the hysterectomy in women with and without preoperatively reported pelvic/lower abdominal pain.Material and methodsThis was a historical cohort study using data from the Swedish National Quality Registry for Gynecological Surgery on 16 694 benign hysterectomies. Data were analyzed using multivariable logistic regression models.ResultsOne year after surgery, 22.4% of women with preoperative pain reported pelvic pain and 7.8% reported de novo pelvic pain. For those with preoperative pain younger age (adjusted odds ratio [aOR] 1.75, 95% confidence interval [CI] 1.38–2.23 and aOR 1.21, 95% CI 1.10–1.34 for women aged <35 and 35–44 years, respectively), not being gainfully employed (aOR 1.43, 95% CI 1.26–1.63), pelvic pain as the main symptom leading to hysterectomy (aOR 1.51, 95% CI 1.19–1.90), endometriosis (aOR 1.18, 95% CI 1.06–1.31), and laparoscopic hysterectomy (aOR 1.30, 95% CI 1.07–1.58), were clinically relevant independent risk factors for pelvic/lower abdominal pain 1 year after surgery, as were postoperative complications within 8 weeks after discharge. Meanwhile, clinically relevant independent risk factors for reporting de novo pain 1 year after surgery were younger age (aOR 2.05, 95% CI 1.08–3.86 and aOR 1.29, 95% CI 1.04–1.60 for women aged <35 and 35–44 years, respectively), and postoperative complications within 8 weeks after discharge.ConclusionsThe incidence of pelvic pain and de novo pain 1 year after hysterectomy was relatively high. Women with and without reported preoperative pelvic/lower abdominal pain represented clinically different populations. The risk factors for pelvic pain seemed to differ in these two populations. The differences in risk factors could be taken into consideration in the preoperative counseling and in the decision‐making concerning method of hysterectomy, provided that large well‐designed studies confirm these risk factors.
The Impact of Institutional Cross‐ownership on Corporate Tax Avoidance: Evidence from Chinese Listed Firms
Authors: Xiao He , Xi Jianqun 
Published: September 2022

AbstractThis study investigates the relationship between institutional cross‐ownership and corporate tax avoidance in Chinese listed firms. Our findings indicate that the tax avoidance aggressiveness of Chinese listed firms could be significantly motivated by institutional cross‐ownership. This finding is robust to endogeneity tests, namely, propensity score matching estimation, two‐stage least squares regression, generalised method of moments test, and a falsification concern. Further, this positive relationship between institutional cross‐ownership and tax avoidance is more pronounced for listed firms with greater managerial ability and those with higher auditor industry expertise. Finally, such a relationship is more obvious for cross‐owners within the same industry, but only significant for independent cross‐owners, non‐state‐owned enterprises and firms within a less competitive industry. All main findings are robust to various robustness tests.
