Authors: Zhang Yajun , Niu Yongge , Chen Zhi , Deng Xiaoyu , Wu Banggang , Chen Yali 
Published: June 2023

PurposeOnline retailers are pioneering the incentivization of customers to generate more product reviews by rewarding them. However, little is known about the impact of reward types on customers' review behavior, including review frequency and sentiment. To address this gap, we investigated the effects of different reward types on customers' review behavior and how these rewards influence customers' review behavior.Design/methodology/approachWe collected secondary data and empirically tested the hypothesis by analyzing the change in reward policy. Regression and two-stage Heckman models were applied to investigate the effects, with the latter used to control potential selection issues.FindingsThe results revealed that monetary rewards can stimulate customers to generate more positive product reviews. Furthermore, the reward amount has a negative moderating effect on the aforementioned relationship. Additionally, customer tenure negatively moderates the relationship between monetary rewards and review behavior.Originality/valueThis study contributes to the understanding of user-generated content motivation and provides managerial implications for reward programs.
A scoping review of police civilian oversight literature 1992–2022
Authors: Keyes Vance D. , Keyes Latocia 
Published: June 2023

PurposeThis study's aim was to systematically review available literature related to the establishment, purpose, operation, and effectiveness of civilian police oversight entities in the United States and to gain a deeper understanding of support, opposition, academic, public, and police expectations concerning their utility.Design/methodology/approach A Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) was used to analyze police civilian oversight literature published between 1992 and 2022.FindingsThe authors find racially biased policing, political investment, police resistance, oversight structure, scope, and authority are key components that determine how oversight is perceived.Research limitations/implications Based on the methodology, the results may not be generalizable. Future researchers should consider expanding public oversight research beyond the parameters, which constrained this paper.Practical implications This article contains implications that should be considered by jurisdictions seeking to develop, restructure, or eliminate public oversight entities and for recognizing the concerns of advocates and opponents of public oversight.Social implications Civilian oversight has long been considered a potential method for public inclusion if not a means for greater public control of police. Over the past few decades, a resurgence of interest in civilian oversight has emerged.Originality/value This article synthesizes literature that spans 30 years of research on public oversight.

Authors: Kim Junhee , Kwon Kibum , Choi Jeehyun 
Published: June 2023

PurposeThis study aims to examine the effect of firm-specific skills on formal and informal training and development (T&D) effectiveness, job satisfaction, turnover intentions, and the moderating effect of job tenure on each hypothesized path. The authors adopt a micro perspective on human capital, arguing its significance to examine the role of job attitudes in developing firm-specific skills.Design/methodology/approachA total of 1,514 South Korean workers' responses were obtained from the Human Capital Corporate Panel dataset. This study conducted structural equation modeling (SEM) to examine the structural relationships between the study variables. A subsequent multigroup SEM was conducted to determine whether the structural model differed across job tenures by comparing the results for employees with more than and less than six years of tenure.FindingsThe findings indicate that (a) firm-specific skills have a negative effect on formal T&D effectiveness and no significant effect on informal T&D effectiveness; (b) firm-specific skills have a negative effect on job satisfaction and no significant effect on turnover intentions; (c) formal T&D effectiveness has a positive effect on job satisfaction and a negative effect on turnover intentions; (d) informal T&D effectiveness has a positive effect on job satisfaction and no significant effect on turnover intentions; and (e) job tenure partially moderates the relationships among the proposed study variables.Originality/valueThe study's findings provide new insights into human capital theory, focusing on whether firm-specific skills can be a source of sustained competitive advantage from employees' perspectives.
Application of Crowdsourcing in User Experience collection – a case study of Malayalam mobile applications
Authors: Sivasankara Pillai Malathi , Balakrishnan Kannan 
Published: June 2023

PurposeThis paper aims to prove the following hypothesis Problem Statement: HYPOTHESIS (1) User Experience collection of mobile applications can be done using the Crowdsourcing mechanism; (2) User Experience collection of mobile applications are influenced by the mindset of Crowdmembers, culture/ethnicity/social background, ease of interface use and rewards, among other factors.Design/methodology/approachThe authors of this paper, did a literature review first to find if Crowdsourcing was applicable and a used method to solve problems in Software Engineering. This helped us to narrow down the application of Crowdsourcing to the Requirements Engineering-Usability (User Experience) collection. User experience collection of two Malayalam language-based mobile applications, AarogyaSetu and BevQ was done as the next step. Incorporating findings from Study I, another study using AarogyaSetu and Manglish was launched as Study II. The results from both cases were consolidated and analyzed. Significant concerns relating to expectations of Crowd members with User Experience collection were unraveled and the purpose of Study was accomplished.Findings(1) Crowdsourcing is and can be used in Software Engineering activities. (2) Crowd members have expectations (motivating factors) of User Interface and other elements that enable them to be an effective contributor. (3) An individual’s environment and mindset (character) are influential in him becoming a contributor in Crowdsourcing. (4) Culture and social practices of a region strongly affects the crowd-participating decision of an individual.Originality/valueThis is purely self-done work. The value of this research work is two-fold. Crowdsourcing is endorsed significant in Software Engineering tasks, especially in User Experience collection of mobile applications. Two, the Crowd service requesters can be careful about designing the questionnaire for Crowdsourcing. They have to be aware and prepared to meet the expectations of the Crowd. This can ensure the active participation of potential contributors. Future researchers can use the results of this work to base their research on similar purposes.

PurposeThis study aims to understand the impact of content orientation, media type, and information richness on fan engagement in multi-sport global events.Design/methodology/approachThe authors conducted a content analysis on Twitter posts recording over two million user impressions from the official account managed by the International Olympic Committee for India during the Tokyo Olympic Games 2020. A multivariate Poisson model using the Bayesian approach was used for analyzing data.FindingsThis study found that fan engagement is likely to be higher for player-oriented content as opposed to team-oriented content. Also, the usage of photos to enhance engagement worked better than any other media type. Finally, the results revealed that the inclusion of hashtags has a positive effect on fan engagement for tweet comments but not for like count and retweet count.Originality/valueThe study highlights the differences in player versus team-oriented posts in global multi-sport competitions. The findings have significant implications for practicing sport managers by informing them about key elements that drive fans to engage in online communication.
Entering the archive of second‐wave trans feminist print culture: The journal of male feminism
Authors: Cousens Emily 
Published: June 2023

AbstractCommon stories of second‐wave feminism equate the period either explicitly or by reference to its presumed biological essentialism, with trans‐exclusionary feminism. This article deep‐dives into issues published between 1977 and 1979 of the Journal of Male Feminism, an underground newsletter for a predominantly North American‐based male‐to‐female (M‐T‐F) cross‐dressing community. It argues that these texts contain a rich set of theoretical resources and nuanced perspectives on sex and gender developed by trans people in the 1970s and therefore deserve to be read as part of an expanded canon of second‐wave feminism.

Published: June 2023

AbstractIt has been reported thatAkkermansia muciniphilaimproves host metabolism and reduces inflammation; however, its potential effects on bile acid metabolism and metabolic patterns in metabolic‐associated fatty liver disease (MAFLD) are unknown. In this study, we have analysed C57BL/6 mice under three feeding conditions: (i) a low‐fat diet group (LP), (ii) a high‐fat diet group (HP) and (iii) a high‐fat diet group supplemented withA. muciniphila(HA). The results found thatA. muciniphilaadministration relieved weight gain, hepatic steatosis and liver injury induced by the high‐fat diet.A. muciniphilaaltered the gut microbiota with a decrease inAlistipes,Lactobacilli,Tyzzerella,ButyricimonasandBlautia, and an enrichment ofRuminiclostridium,Osclibacter,Allobaculum,AnaeroplasmaandRikenella. The gut microbiota changes correlated significantly with bile acids. Meanwhile,A. muciniphilaalso improved glucose tolerance, gut barriers and adipokines dysbiosis.Akkermansia muciniphilaregulated the intestinal FXR‐FGF15 axis and reshaped the construction of bile acids, with reduced secondary bile acids in the caecum and liver, including DCA and LCA. These findings provide new insights into the relationships between probiotics, microflora and metabolic disorders, highlighting the potential role ofA. muciniphilain the management of MAFLD.
EcoEnsemble: A general framework for combining ecosystem models in R
Authors: Spence Michael A. , Martindale James A. , Thomson Michael J. 
Published: June 2023

Abstract

Often there are several complex ecosystem models available to address a specific question. However, structural differences, systematic discrepancies and uncertainties mean that they typically produce different outputs. Rather than selecting a single ‘best’ model, it is desirable to combine them to give a coherent answer to the question at hand.

Many methods of combining ecosystem models assume that one of the models is exactly correct, which is unlikely to be the case. Furthermore, models may not be fitted to the same data, have the same outputs, nor be run for the same time period, making many common methods difficult to implement. In this paper, we use a statistical model to describe the relationship between the ecosystem models, prior beliefs and observations to make coherent predictions of the true state of the ecosystem with robust quantification of uncertainty.

We introduce EcoEnsemble, an R package that takes advantage of the statistical model's structure to efficiently fit the ensemble model, either sampling from the posterior distribution or maximising the posterior density.

We demonstrate EcoEnsemble by investigating what would happen to four fish species in the North Sea under future management scenarios. Although developed for applications in ecology, EcoEnsemble can be used to combine any group of mechanistic models, for example in climate modelling, epidemiology or biology.
Estonia: Political Developments and Data in 2022
Authors: MÖLDER MARTIN 
Published: June 2023

AbstractThe Russian‐Ukrainian war, which started in February 2022, changed Estonian domestic politics considerably. The Reform Party, which had failed to manage domestic crises at the end of 2021, was able to prove itself in foreign politics, and its support skyrocketed. Its coalition partner at the start of the war, the Centre Party, however, lost support, which eventually led to the break‐up of the government coalition in the middle of the year. A new government was formed by the Reform Party, Fatherland and the Social Democratic Party, which was limited in its ambitions and cautious of its political choices as elections were approaching in March 2023.
CAG and GGN repeat polymorphisms in the androgen receptor gene of a Chilean pediatric cohort with idiopathic inguinal cryptorchidism

Published: June 2023

AbstractBackgroundCryptorchidism is one of the most common congenital disorders in boys and it is associated with a higher risk of sub‐fertility and testicular cancer. Testicular descent occurs during embryo‐fetal development in two phases, transabdominal and inguino‐scrotal. In the latter process, androgens play a leading role. The androgen receptor has in its N‐terminal domain, two aminoacidic repeats encoded by polymorphic nucleotide repetitions: (CAG)nCAA and GGN. The number of repetitions of these trinucleotides has been associated with different transactivation capacities and sensitivities of the androgen receptor response.ObjectiveTo determine whether pediatric Chilean individuals with idiopathic inguinal cryptorchidism have a different number of CAG and/or GGN repeats polymorphisms compared with controls.Materials and methodsA total of 109 cases with idiopathic inguinal cryptorchidism (26 bilateral and 83 unilateral) were studied by polymerase chain reaction amplification from DNA extracted from peripheral blood, followed by fragment size analysis by capillary electrophoresis, which were compared with 140 controls.ResultsThe CAG26 repeats allele was increased in the total cases (8.3% vs. 1.4%; p = 0.012; odds ratio = 6.21, 95% confidence interval 1.31–29.4), and in bilateral cases compared to controls (11.5% vs. 1.4%; p = 0.028; odds ratio = 9 CI 95% 1.43–56.8). Similarly, CAG > 22 alleles were increased in the total cases (62.4% vs. 49.3%, p = 0.041), and more significantly in bilateral cases (73.1% vs. 49.3%; p = 0.032; odds ratio = 2.79, 95% confidence interval 1.1–7.1). In addition, CAG < 18 alleles were not observed among cases, but were present in 5.7% of controls (p = 0.01). Regarding the GGN repeats, no differences were observed between cases and controls either when analyzing separately unilateral and bilateral cryptorchidism. The joint analysis of the distribution of CAG and GGN alleles showed that the CAG26 allele was present with GGN23, hence the combination CAG26/GGN23 alleles was equally increased in bilateral cases compared with controls (11.5% vs. 1.4%). In contrast, CAG < 18 was preferably observed in the combination CAG < 18/GGN≠23 and was absent in the total cases (4.3% vs. 0%; p = 0.037).DiscussionThese results suggest that greater lengths of CAG alleles may contribute to a diminished androgen receptor function. The CAG26 allele alone or in combination with GGN23 was associated with a higher risk of bilateral cryptorchidism. On the other hand, CAG < 18 and the CAG < 18/GGN≠23 allele combination may reduce the probability of cryptorchidism.
How does deprescribing (not) reduce mortality? A review of a meta‐analysis in community‐dwelling older adults casts uncertainty over claimed benefits
Authors: Sirois Caroline , Gosselin Maude , Laforce Camille , Gagnon Marie‐Eve , Talbot Denis 
Published: June 2023

AbstractSome meta‐analyses suggest that deprescribing may reduce mortality. Our aim was to determine the underlying factors contributing to this observed reduction. We analysed data from 12 randomized controlled trials included in the latest meta‐analysis on deprescribing in community‐dwelling older adults. Our analysis focused on deprescribed medications and potential methodological concerns. Only a third (4/12) of the trials aimed to study mortality, and that too as a secondary outcome. Five trials reported a reduction in total medications, potentially inappropriate medications or drug‐related problems. Information on specific classes of deprescribed medications was limited, although a wide array was concerned (e.g., antihypertensive, sedative, gastro‐intestinal medications and vitamins). Follow‐up periods were ≤1 year in 11 trials, and five trials included ≤150 participants. Small sample sizes often resulted in imbalanced groups (e.g., comorbidities, number of potentially inappropriate medications), yet no trials presented multivariable analyses. In the two trials with the most weight in the meta‐analysis, several deaths occurred before the intervention, making it difficult to draw conclusions about the impact of the deprescribing intervention on mortality. These methodological issues cast significant uncertainty on the benefits of deprescribing on mortality outcomes. Large‐scale, well‐designed trials are needed to address this issue effectively.
Subtype‐specific modulation of human KV7 channels by the anticonvulsant cannabidiol through a lipid‐exposed pore‐domain site

Published: June 2023

AbstractBackground and PurposeCannabidiol (CBD) is used clinically as an anticonvulsant. Its precise mechanism of action has remained unclear. CBD was recently demonstrated to enhance the activity of the neuronal KV7.2/7.3 channel, which may be one important contributor to CBD anticonvulsant effect. Curiously, CBD inhibits the closely related cardiac KV7.1/KCNE1 channel. Whether and how CBD affects other KV7 subtypes remains uninvestigated and the CBD interaction sites mediating these diverse effects remain unknown.Experimental ApproachHere, we used electrophysiology, molecular dynamics simulations, molecular docking and site‐directed mutagenesis to address these questions.Key ResultsWe found that CBD modulates the activity of all human KV7 subtypes and that the effects are subtype dependent. CBD enhanced the activity of KV7.2–7.5 subtypes, seen as a V50 shift towards more negative voltages or increased maximum conductance. In contrast, CBD inhibited the KV7.1 and KV7.1/KCNE1 channels, seen as a V50 shift towards more positive voltages and reduced conductance. In KV7.2 and KV7.4, we propose a CBD interaction site at the subunit interface in the pore domain that overlaps with the interaction site of other compounds, notably the anticonvulsant retigabine. However, CBD relies on other residues for its effects than the conserved tryptophan that is critical for retigabine effects. We propose a similar, though not identical CBD site in KV7.1, with a non‐conserved phenylalanine being important.Conclusions and ImplicationsWe identify novel targets of CBD, contributing to a better understanding of CBD clinical effects and provide mechanistic insights into how CBD modulates different KV7 subtypes.
Eocene to present evolution of the Pearl River, China: A quantitative provenance interpretation on large detrital zircon U–Pb geochronological data

Published: June 2023

AbstractDrainage evolution of the Pearl River, one of the major rivers in the eastern margin of the Asian continent, has important implications for the tectonomorphic evolution of the northern margin of the South China Sea and the southeastern Tibetan Plateau. Previous reconstructions using different methods suggested discrepant timings for the formation of river, ranging from Early Oligocene to Middle Miocene. Here, we address this heavily debated topic using quantitative unmixing modelling of detrital zircon data from the Pearl River Mouth Basin in the northern margin of the South China Sea. In this study, we develop a novel approach for estimating the relative contributions of detrital zircon sources to their shared sink, and propose to use the correlation coefficients among zircon contribution models to evaluate the trade‐off among sources with similar age spectra, to avoid the potential overinterpretation of individual contributions. Our new method is applied to new (997) and published detrital zircon U–Pb data from offshore boreholes and modern Pearl River samples to quantitatively interpret and reconstruct the sediment provenance of the Pearl River Mouth Basin and the development of the Pearl River. Our findings reveal that the provenance change of the Pearl River Mouth Basin can be divided into three main stages. Eocene sediments were mainly sourced in the intra‐basinal highlands and the eastern coastal tributaries, indicating a local drainage system. Early Oligocene provenances extended westward, as shown by the increase in sediment contribution from the central and western parts of the Pearl River (28% in total). Since the Late Oligocene, the eastern, central and western parts of the modern Pearl River have contributed equal amounts of zircons to the Pearl River Mouth Basin, indicating the establishment and long‐term stability of the modern‐like drainage system, as highlighted by our new data acquired from the borehole Miocene strata. The Late Oligocene westward expansion of the Pearl River is consistent with the timing of the coeval breakup and spreading of the South China Sea and the intensified Asian monsoon precipitation, highlighting the importance of base level fall and climate in controlling the drainage evolution.
