Structure of the deuteron from an analysis of bremsstrahlung emission in proton-deuteron scattering in cluster models
Authors: Shaulskyi K. A. , Maydanyuk S. P. , Vasilevsky V. S. 
Published: September 2024

Emission of bremsstrahlung photons in the scattering of protons off deuterons is investigated on the microscopic cluster basis in a wide region of beam energy from low energies up to 1.5 GeV.
Our aim is to construct a model extracting new information about the structure of the deuteron from analysis of accompanying bremsstrahlung in proton-deuteron scattering.
A three-cluster model of bremsstrahlung is constructed. The formalism includes the form factor of the deuteron, which characterizes the dependence of bremsstrahlung cross sections on the structure of the deuteron. This gives a possibility to investigate the structure of nuclei from analysis of bremsstrahlung cross sections.
We studied the dependence of the bremsstrahlung cross section on the structure of the deuteron. We used three different shapes of the deuteron wave functions. Besides, we also calculated the cross section by neglecting the internal structure of the deuteron. Analysis of the dependence of the cross section on such a parameter shows the following. (1) At beam energies 145 and 195 MeV used in experiments, the bremsstrahlung cross section is not sensitive enough to variations in the shape of the deuteron wave functions. (2) A stable difference between cross sections calculated with and without the internal structure of the deuteron is observed at higher bean energy (higher than 500 MeV). (3) The spectrum is increased as we pass from the structureless deuteron (the oscillator length b=0) to the deuteron described by the shell-model wave function (the realistic oscillator length) inside the full energy region of the emitted photons.
Our cluster model is a suitable tool to study the structure of the deuteron with high enough precision from bremsstrahlung analysis. We propose new experiments for such an investigation.Published by the American Physical Society2024
Phase of the electromagnetic form factor of the pion
Authors: Ruiz Arriola Enrique , Sanchez-Puertas Pablo 
Published: September 2024

We employ a dispersion relation that allows us to recover the phase of the electromagnetic form factor of the pion from its absolute value above threshold. Compared to alternative approaches building on the phase, this approach builds on experimental input directly accessible at colliders. Employing the precise datasets from the e+e−→π+π− reaction, we obtain the phase of the electromagnetic form factor up to 2.5 GeV, well beyond standard dispersive approaches. In addition, we separate the isovector and isoscalar components, that allows us to extract the P-wave ππ phase shift. We also provide relevant results, including the radius of the form factor and bounds in the spacelike region. Last, but not least, the study assess potential systematic uncertainties from the interpolation method and potential zeros of the form factor.

. The ligands used were 4-sulfobenzoate (PSB) and pyridine-4-carbohydrazide, popularly known as isoniazid (INH), an antibiotic drug. The compound crystallizes in the monoclinic space group C2/c, with Z = 4. Solid-state calculations suggest that the crystal structure is mainly stabilized by hydrogen bonds, i.e. O—H...O and N—H...O interactions among the polymers, and by van der Waals interactions involving the organic side chains. This net is tetragonal, 2-nodal 3,4-connected, and can be described as the dmd (sqc 528) type.
The failure of the United Kingdom’s accounting and fiscal governance
Authors: Heald David , Hodges Ron 
Published: September 2024

PurposeThis paper aims to unravel the puzzle that the United Kingdom’s high-quality government accounting and fiscal architecture is associated with low-quality outcomes, including poor productivity growth, high public debt, public services which do not meet citizen expectations and historically high levels of taxation. It contributes to public sector accounting research in the fields of fiscal transparency and governance.Design/methodology/approachThis paper uses Miller and Power’s (2013) economization framework and Dunsire’s (1990) concept of collibration to explain why being a global leader in public sector accounting reform and in fiscal and monetary architecture has not protected the UK from weak governance. The intersection of economization’s roles of accounting with modes of government accounting clarifies the puzzle.FindingsWhereas accruals government accounting contributes to fiscal transparency, this is not a sufficient condition for well-judged policy and its effective application. Collibration is the dominant mechanism for mediation in the fiscally centralized UK, but it has failed to deliver stable outcomes, in part because Parliament is limited in its ability to hold back inappropriate behaviour by the Executive. Subjectivization has disrupted adjudication because governments at all levels resist constraints on their behaviour, with unpredictable and often damaging consequences.Originality/valueThis paper provides insights through the combined lens of economization and modes of government accounting, demonstrating the practical value of this conceptualization. Although some causes for unsatisfactory outcomes are specific to the UK, there are cautions for accounting and fiscal reformers in other countries, such as Member States of the European Union.

PurposeThis study aimed to uncover the characteristics of both misinformation and refutations as well as the associations between different aspects of misinformation and corresponding ways of rebutting it.Design/methodology/approachLeveraging Hovland's persuasion theory as a research lens and taking data from two Chinese refutation platforms, we characterized the topics of COVID-19-related misinformation and refutations, misinformation communicator, persuasion strategies of misinformation, refutation communicators and refutation strategies based on content analysis. Then, logistic regressions were undertaken to examine how the characteristics of misinformation and refutation strategies interacted.FindingsThe investigation into the association between misinformation and refutations found that distinct refutation strategies are favored when debunking particular types of misinformation and by various kinds of refutation communicators. In addition, several patterns of persuasion strategies were identified.Research limitations/implicationsThis study had theoretical and practical implications. It emphasized how misinformation and refutations interacted from the perspective of Hovland's persuasion theory, extending the scope of the existing literature and expanding the classical theory to a new research scenario. In addition, several patterns of persuasion strategies used in misinformation and refutation were detected, which may contribute to the refutation practice and help people become immune to misinformation.Originality/valueThis research is among the first to analyze the relationships between misinformation and refutation strategies. Second, we investigated the persuasion strategies of misinformation and refutations, contributing to the concerning literature. Third, elaborating on Hovland’s persuasion theory, this study proposed a comprehensive framework for analyzing the misinformation and refutations in China during the COVID-19 pandemic.

Do employees with high human capital hide knowledge? Exploring mediation and moderation mechanisms
Authors: Kmieciak Roman 
Published: September 2024

PurposeKnowledge hiding in organizations is perceived as counterproductive knowledge behavior that is negatively related to employees creativity and job performance, but positively affect workplace deviance and turnover intention. The extent to which knowledge hiding develops is largely determined by personal characteristics and the work environment. However, there is a lack of research on the relationship between individual intellectual capital and knowledge hiding. This study aims to investigate the underlying mediation and moderation mechanisms of the relationship between individual human capital and knowledge hiding. The study explores the mediating role of pressure of helping others and negative emotions, and the moderating role of perceived organizational politics.Design/methodology/approachThe data were collected in two waves, in January and February 2024, from 424 Polish employees with high intellectual capital. Partial least squares path modeling was used to test the research hypotheses.FindingsIndividual human capital is positively related to the pressure of helping others and negatively related to negative emotions. Pressure of helping others mediates the relationship between individual human capital and knowledge hiding. Contrary to expectations, negative emotions do not mediate the relationship between the pressure of helping others and knowledge hiding. The interaction of individual human capital and perceived organizational politics is positively related to knowledge hiding.Practical implicationsTo decrease knowledge hiding, managers should promote meritocracy in the organization and reduce employees’ behaviors that are selfish and based on political games. Employees with high human capital should be provided with support to relieve the pressure of helping others and the negative emotions which are associated with the pressure of helping others.Originality/valueBased on psychological ownership and reactance theories, to the best of the author’s knowledge, this study is the first to explore the relationships between individual human capital and knowledge hiding.

Purpose
Drug trafficking in the tiny state of Manipur, located in the northeastern part of India bordering Myanmar, has drawn attention from all over the globe looking at the scale and varieties of drugs trafficked, ranging from plant-based opiates to synthetic-based amphetamine-type stimulants (ATS). Moreover, drug trafficking in the region also comes with many socio-political dynamics such as high per-capita drug consumption, local drug manufacturing units, terror funding from drug money, politician–drug lord nexus, police–peddler nexus.

Design/methodology/approach
The study is based on data from the years 2007 to 2023 accessed from the Narcotics and Affairs of Borders, a specialized branch of Manipur Police, Government of Manipur. The study also tries to estimate the state’s drug economy using the Financial Action Task Force and the United Nations Office on Drugs and Crime methodology.

Findings
The study finds seizure of a massive cache of heroin/brown sugar, and ATS in the past 4–5 years. The study also finds large-scale destruction of poppy plants in the state. The study also finds a high percentage of ethnic minority communities involved in drug trafficking. The study found the value amounting to US$62m in 2022. The study also comes across low conviction rates of drug traffickers in the state.

Originality/value
The study emphasizes the need for expediting the War on Drugs campaign in the state curtailing poppy cultivation and conviction of drug lords so that the nerve center of terror funding in India’s eastern front is kept under control.

PurposeThe main objective of the present investigation is to develop a novel efficient stochastic model for availability optimization of reverse osmosis machine system (ROMS) for water purification under the concepts of exponentially distributed decision variables and various redundancy strategies at the component level.Design/methodology/approachROMS is a complex framework configured in a series structure using six subsystems. Initially, a state transition diagram is developed and Chapman–Kolmogorov differential-difference equations are derived using Markov birth death process. The steady-state availability of the ROMS is derived for a particular case. The impact of variation in failure and repair rates measured on availability. Furthermore, an effort is made to predict the optimal availability of the ROMS system using the metaheuristic algorithms, namely, dragonfly algorithm (DA), grasshopper optimization algorithm (GOA) and whale optimization algorithm (WOA).FindingsIt is observed that the ROMS system predicts optimal availability of 0.999926 after five iterations with a population size of 300 by the WOA. The findings of this study are significant for reliability engineers as well as for maintenance engineers to ensure the availability of ROMS for water purification.Originality/valueIn the present investigation, a novel stochastic model is developed for ROMS, and metaheuristics algorithms are applied to predict the optimal availability.
An integrated decision-making model for green supplier selection based on AIOWA-CRITIC and CPT-TOPSIS: a case study of China
Authors: Zhao Hui , Lu Chen , Wang Simeng 
Published: September 2024

PurposeAs environmental protection and sustainable development become more widely recognized, greater emphasis has been placed on the significance of green supplier selection (GSS), which can support businesses both upstream and downstream in enhancing their environmental performance while preserving their strategic competitiveness. Therefore, this paper aims to propose a new framework to study GSS.Design/methodology/approachFirstly, this paper establishes a GSS evaluation criteria system including product competitiveness, green performance, quality of service and enterprise social responsibility. Secondly, based on the spherical fuzzy sets (SFSs), the Average Induction Ordered Weighted Averaging Operator-Criteria Importance Through Inter Criteria Correlation (AIOWA-CRITIC) method is used to determine the subjective and objective weights and the combination of weights are determined by game theory. In addition, the GSS framework is constructed by the Cumulative Prospect Theory-Technique for Order Preference by Similarity to Ideal Solution (CPT-TOPSIS) method. Finally, the validity and robustness of the framework is verified through sensitivity comparative and ablation analysis.FindingsThe results show that Y3 is the most promising green supplier in China. This study provides a feasible guidance for GSS, which is important for the greening process of the whole supply chain.Originality/valueUnder spherical fuzzy sets, AIOWA and CRITIC are used to determine weights of indicators. CPT and TOPSIS are combined to construct a decision model, considering the ambiguity and uncertainty of information and the risk attitudes of decision-makers.
Foreign direct investment and export expansion: political connection and innovative performance
Authors: Yang Yi , Zhao Jing , Yang Young Soo 
Published: September 2024

PurposeThis study investigates two internationalization strategies, foreign direct investment (FDI) expansion and export expansion, and their effects on the innovation performance of Chinese multinational enterprises (MNEs). Additionally, it explores the moderating roles of both formal and informal political connections in the relationship between these internationalization strategies and innovation performance.Design/methodology/approachThe hypotheses were tested using the Poisson panel model and data on 2,106 observations from 645 Chinese-listed firms between 2010 and 2017.FindingsFDI expansion significantly enhances the innovation performance of Chinese MNEs compared to export expansion. Moreover, formal and informal political connections are found to have distinct moderating effects: formal political connections amplify the positive effect of FDI expansion on firm innovation, whereas informal political connections tend to weaken it.Originality/valueThis study contributes to the discourse on innovation and political connections, especially in the context of EMNEs. It enriches the theoretical understanding of internationalization strategies and innovation performance in EMEs, contrasting with the technology-utilization motives observed in MNEs from developed economies.
Understanding the impact of government social media on citizens’ unverified information avoidance behavior during health crises: the health belief model
Authors: Dong Xueyan , Tang Zhenya , Wang Houcai 
Published: September 2024

PurposeUnverified information avoidance behavior refers to the conscious effort made by individuals to avoid consuming information that has not been verified by credible sources. This behavior is essential in preventing the spread of misinformation that can hinder effective public health responses. While previous studies have examined information avoidance behavior in general, there is a lack of research specifically focusing on the avoidance of unverified information during health crises. This study aims to fill this gap by exploring factors that lead to social media users’ unverified information avoidance behavior during health crises, providing novel insights into the determinants of this protective behavior.Design/methodology/approachWe based our research model on the health belief model and validated it using data collected from 424 individuals who use social media. The proposed model was tested by using the partial least squares structural equation modeling (PLS-SEM) approach.FindingsOur results indicate that individuals’ government social media participation (following accounts and joining groups) affects their health beliefs (perceived severity and benefits of information avoidance), which in turn trigger their unverified information avoidance behavior.Originality/valueOur study contributes to the current literature of social media crisis management and information avoidance behavior. The implications of these findings for policymakers, social media platforms and theory are further discussed.

Published: September 2024

AbstractObservational studies have suggested an associations between hidradenitis suppurativa (HS) and metabolic syndrome (MetS) and its components. However, it remains unclear whether the relationship is causal or not. Our study aimed to investigate the causal association of HS with MetS and its components. We performed a bidirectional, two‐sample Mendelian randomization study using summary‐level data from the most comprehensive genome‐wide association studies of HS (n = 362 071), MetS (n = 291 107), waist circumference (n = 462 166), hypertension (n = 463 010) fasting blood glucose (FBG, n = 200 622), triglycerides (n = 441 016), and high‐density lipoprotein cholesterol (HDL‐C, n = 403 943). Genetic instrumental variables were constructed by identifying single nucleotide polymorphisms associated with the corresponding factors. The random‐effects inverse‐variance weighted method was applied as the primary method. The results showed that genetically predicted HS was positively associated with waist circumference risk in both directions. High waist circumference increased the risk of HS (odds ratio [OR] 4.147; 95% confidence interval [CI] 2.610–6.590; p = 1.746 × 10−9). In addition, HS was also affected by waist circumference (OR 1.009; 95% CI 1.006–1.012; p = 3.08 × 10−7). No causal relationships were found between HS and MetS or its components other than waist circumference. The findings highlight the importance of early intervention for obesity in HS patients. Further studies are needed to determine the pathophysiology of HS associated with MetS and its components.
