Influencers' intimate self-disclosure and its impact on consumers' self-brand connections: scale development, validation, and application
Authors: Leite Fernanda Polli , Baptista Paulo de Paula 
Published: September 2021

PurposeThis study develops and validates a scale to measure social media influencers' intimate self-disclosure (SMIs' ISD), by accessing consumer perceptions of the intimacy levels of SMIs' self-disclosure. The authors further evaluate the extent to which SMIs' ISD fosters consumers' self-brand connections via consumer-SMI parasocial relationships.Design/methodology/approachThe scale was developed through item generation, purification, and validation. First, items were generated from existing scales and revised based on feedback provided by experts. The items were subjected to exploratory and confirmatory factor analyses using an online survey with 433 participants. Structural equation modeling (SEM) was used to examine the predictive power of SMIs' ISD on parasocial relationships and self-brand connections.FindingsThe results suggest that the perceived SMIs' ISD is a unidimensional construct. As proposed, SMIs' ISD enhances consumer-brand connections through the underlying mechanism of consumers' sense of being in a parasocial relationship with an SMI.Originality/valueThis study advances self-disclosure and influencer marketing literature by addressing the lack of measures on SMIs' ISD from a consumer perspective and the scarcity of empirical understanding of how brands can profit from SMIs' capabilities to make intimate self-disclosure. Based on the literature review, this study is the first to empirically consider factual, emotional, and cognitive intimacy to develop scale and demonstrate the importance of SMIs' ISD in developing consumers' self-brand connections.
The link between extraversion and service outputs: a moderated mediation model of work vigor and coworker support
Authors: Hu Wan-Hsien , Lin Chen-Ju 
Published: September 2021

PurposeBased on the broaden-and-build theory, this study aims to clarify that the relationship between extraversion and service outcomes will be mediated by work vigor, and that, in turn, this mediating effect will be moderated by coworker support. Specifically, the authors examine vigor as an attitudinal resource to drive organizational performance.Design/methodology/approachThis research collected 181 valid questionnaires from service industries through a two-wave survey. The authors used hierarchical regression analysis to conduct each hypothesis test. Owing to the conditional mediating effect, the authors differentiated each variable centering and used the fractional number and the product as the predictor variable, moderator, and interaction effects after centering.FindingsThe relationships between extraversion and customer orientation and service performance mediated by work vigor in that the indirect relationships are stronger when perceived coworker support is higher than is lower.Research limitations/implicationsFuture studies are suggested to probe into different forms of social support (e.g. family support), mechanisms of coworker support (e.g. task-related vs. non-task-related assistance), and different workplace contexts.Practical implicationsExtraversion, as a personality trait, is a significant reference index to examine an applicant's qualifications during recruitment, particularly in service organizations. Appropriate job assistance and emotional conciliation from coworkers can effectively facilitate employees' work vigor and service outputs.Originality/valuePrevious studies suggested the influence of different personality traits on different dimensions of work engagement. Accordingly, investigation indicates that extraversion can effectively predict work vigor which is an important attitude of willingness to put personal efforts at work to facilitate frontline service outcomes.
Carrots or sticks in debt collection services? A voice metrics and text analysis of debt collection calls
Authors: Liao Chengcheng , Du Peiyuan , Yang Yutao , Huang Ziyao 
Published: September 2021

PurposeAlthough phone calls are widely used by debt collection services to persuade delinquent customers to repay, few financial services studies have analyzed the unstructured voice and text data to investigate how debt collection call strategies drive customers to repay. Moreover, extant research opens the “black box” mainly through psychological theories without hard behavioral data of customers. The purpose of our study is to address this research gap.Design/methodology/approachThe authors randomly sampled 3,204 debt collection calls from a large consumer finance company in East Asia. To rule out alternative explanations for the findings, such as consumers' previous experience of being persuaded by debt collectors or repeated calls, the authors selected calls made to delinquent customers who had not been delinquent before and were being called by the company for the first time. The authors transformed the unstructured voice and textual data into structured data through automatic speech recognition (ASR), voice mining, natural language processing (NLP) and machine learning analyses.FindingsThe findings revealed that (1) both moral appeal (carrot) and social warning (stick) strategies decrease repayment time because they arouse mainly happy emotion and fear emotion, respectively; (2) the legal warning (stick) strategy backfires because of decreasing the happy emotion and triggering the anger emotion, which impedes customers' compliance; and (3) in contrast to traditional wisdom, the combination of carrot and stick fails to decrease the repayment time.Originality/valueThe findings provide a valuable and systematic understanding of the effect of carrot strategies, stick strategies and the combinations of them on repayment time. This study is among the first to empirically analyze the effectiveness of carrot strategies, stick strategies and their joint strategies on repayment time through unstructured vocal and textual data analysis. What's more, the previous studies open the “black box” through psychological mechanism. The authors firstly elucidate a behavioral mechanism for why consumers behave differently under varying debt collection strategies by utilizing ASR, NLP and vocal emotion analyses.
A new conceptual model for assessing the role of knowledge cloud in stimulating subordinate creativity
Authors: Xiao Wen Hong , Wang M. 
Published: September 2021

PurposeThe knowledge cloud links people and ideas while also providing worldwide resources for putting them into action. This paper aims to see how the knowledge cloud affects the stimulation of subordinate creativity. The impact of the knowledge cloud on transformational leadership and its impacts on subordinate creativity are examined in this investigation. Also, this study checks out the influence of knowledge cloud on motivational goal orientation and the impact of motivational goal orientation on subordinate creativity. It investigates the influence of knowledge cloud on self-efficacy and feelings of it on subordinate creativity. Moreover, this research examines the impact of the knowledge cloud on employee empowerment and its impact on subordinate creativity.Design/methodology/approachKnowledge sharing is known as a human rationale for information. It promotes learning, human performance, decision-making and problem-solving at the job; thus, innovation and creativity need novel knowledge. Knowledge cloud is a knowledge source that provides a base for knowledge co-creation. This investigation explores the structural relationships among knowledge cloud, transformational leadership, motivational goal orientation, self-efficacy, employee empowerment and subordinate creativity. Here, a model is improved and experimentally examined based on the knowledge cloud, transformational leadership, motivational goal orientation, self-efficacy and employee empowerment to improve subordinate creativity using partial least squares (PLS) and data from car factories' employees in Beijing.FindingsThe study results show that knowledge cloud, transformational leadership, motivational goal orientation, self-efficacy and employee empowerment are strongly related to subordinate creativity. In addition to using the Sobel test, all four variables' mediating role (transformational leadership, motivational goal orientation, self-efficacy and employee empowerment) is confirmed.Practical implicationsA knowledge cloud can improve the stimulating subordinate creativity of employees through transformational leadership, motivational goal orientation, self-efficacy and employee empowerment. First, the human resources department must have some programs to improve the knowledge cloud's incentive. Second, creating an atmosphere of cooperation and trust among employees should enhance the knowledge cloud's effects.Originality/valueTo the authors' knowledge, this is the first study that addresses the knowledge cloud's role in subordinate creativity in firms. This investigation also assists the creativity literature by testing the mediating effect of motivational goal orientation, transformational leadership, feelings of self-efficacy and employee empowerment.

Abstract

Biologging technology is rapidly advancing—scientists are obtaining data on movement and behaviour for a range of species, more accurately than ever before. With this information, it is possible to understand more about important areas and their connections across the open ocean including the high seas, beyond national jurisdictions. But an absence of a global governance framework has so far hindered a coordinated approach to conservation action on the high seas.

We showcase a candidate high seas MPA in the Northeast Atlantic identified primarily from seabird tracking data and being taken forward under a regional process: the North Atlantic Current and Evlanov Seamount (NACES) MPA, under the OSPAR Commission. It provides a unique case study to learn about the intricacies of implementation when applying tracking information for conservation. From this, we identify the facilitating conditions and challenges faced from identification to designation and highlight actionable opportunities for future area‐based management of the high seas that will be made possible under a new agreement.

Policy implications. The North Atlantic Current and Evlanov Seamount (NACES) MPA demonstrates the power of translating tracking data into usable geospatial knowledge to inform conservation and policy and provides an exemplar for a data‐driven approach to high seas conservation that can become a reality under the forthcoming governance framework (under the United Nations Convention on the Law of the Sea on the conservation and sustainable use of marine biological diversity of areas beyond national jurisdiction (known as the BBNJ Agreement)). This new agreement presents a unique conservation opportunity both for the application of tracking data to conservation outcomes and for the protection of migratory species.

AbstractNowadays, quinoline scaffold is among the most vital construction compounds for the development of new drugs. The purpose of this research is to evaluate the anti‐cancer activity of sodium salt of ethyl (E)‐2‐cyano‐3‐(7‐hydroxy‐4‐methyl‐2‐oxoquinoline‐1(2H)‐yl)‐3‐(4‐hydroxyphenyl) acrylate against Ehrlich ascites carcinoma (EAC) cells residing in female mice's peritoneal cavity. The docking study exhibited a favourable interaction between the compound and the receptors 1MOY and 3KJF of osteopontin and caspase 3, respectively. The compound's sodium salt showed potential antioxidant and anti‐cancer effects against Ehrlich ascites carcinoma (EAC) cells in vivo. Herein, the results elucidated that treatment with the compound's sodium salt exerted significant chemopreventive and chemotherapeutic effects, which reduced both EAC cell volume and count. Our results revealed that treatment with the sodium salt of the compound demonstrated a remarkable in vivo apoptotic effect through elevation of the expression of caspase 3 and reduction of osteopontin levels. Histopathological examination confirmed that the compound's sodium salt improved liver and kidney tissues without any apparent adverse effects.

ObjectiveTo examine postpartum haemorrhage (PPH) trends in Sweden using the Robson classification system.DesignPopulation‐based cohort study.SettingSweden.PopulationDeliveries in 2000–2016, classified as Robson groups 1–5 (singleton pregnancies in vertex presentation, from gestational weeks 37+0; n = 1 590 178).MethodsWe examined temporal trends in PPH between 2000 and 2016 overall, and within each Robson group, and performed logistic regression to examine the influence of changes in risk factors (maternal, comorbidity, obstetric practice and infant factors) over time.Main outcome measuresPostpartum haemorrhage, defined as an estimated blood loss of >1000 ml.ResultsThe overall PPH rate increased from 5.4 to 7.3%, corresponding to a 37% (OR 1.37, 95% CI 1.32–1.42) increase over time. Rates varied between Robson groups, ranging from 4.5% in group 3 to 14.3% in group 4b. Increasing trends in PPH were found in all Robson groups except for groups 2b and 4b (prelabour caesarean deliveries). In the unstratified analysis, adjusting for maternal, comorbidity and obstetric practice factors slightly attenuated the risk of PPH in the later period (2013–2016), compared with the reference period (2000–2004; crude OR 1.26, 95% CI 1.24–1.29, adjusted OR 1.22, 95% CI 1.20–1.25). Within individual Robson groups, changes in risk factors did not explain increasing rates of PPH.ConclusionsPostpartum haemorrhage rates varied between Robson groups. Changes in risk factors could not explain the 37% increase in PPH for women in Robson groups 1–5 in Sweden, 2000–2016.Tweetable abstractChanges in risk factors could not explain the increasing trend of PPH in Sweden, and rates of PPH varied widely between Robson groups.
Chronic hypertension, perinatal mortality and the impact of preterm delivery: a population‐based study
Authors: Grover S , Brandt JS , Reddy UM , Ananth CV 
Published: September 2021

ObjectivesTo estimate the association between chronic hypertension and perinatal mortality and to evaluate the extent to which risks are impacted by preterm delivery.DesignCross‐sectional analysis.SettingUnited States, 2015–18.PopulationSingleton births (20–44 weeks of gestation).ExposureChronic hypertension, defined as elevated blood pressure diagnosed before pregnancy or recognised before 20 weeks of gestation.Main outcomes and measuresWe derived the risk of perinatal mortality in relation to chronic hypertension from Poisson models, adjusted for confounders. The impacts of misclassification and unmeasured confounding were assessed. Causal mediation analysis was performed to quantify the impact of preterm delivery on the association.ResultsOf the 15 090 678 singleton births, perinatal mortality rates were 22.5 and 8.2 per 1000 births in chronic hypertensive and normotensive pregnancies, respectively (adjusted risk ratio 2.05, 95% CI 2.00–2.10). Corrections for exposure misclassification and unmeasured confounding biases substantially increased the risk estimate. Although causal mediation analysis revealed that most of the association of chronic hypertension on perinatal mortality was mediated through preterm delivery, the perinatal mortality rates were highest at early term, term and late term gestations, suggesting that a planned early term delivery at 37–386/7 weeks may optimally balance risk in these pregnancies. Additionally, 87% (95% CI 84–90%) of perinatal deaths could be eliminated if preterm deliveries, as a result of chronic hypertension, were preventable.ConclusionsChronic hypertension is associated with increased risk for perinatal mortality. Planned early term delivery and targeting modifiable risk factors for chronic hypertension may reduce perinatal mortality rates.Tweetable abstractMaternal chronic hypertension is associated with increased risk for perinatal mortality, largely driven by preterm birth.

Published: September 2021

AbstractBackgroundPregnancy and childbirth increase the risk for pelvic floor dysfunction, including sexual dysfunction. So far, the mechanisms and the extent to which certain risk factors play a role remain unclear.ObjectivesIn this systematic review of the literature we aimed to determine risk factors for sexual dysfunction in the first year after childbirth.Search StrategyWe searched MEDLINE, Embase and CENTRAL using the search strategy: sexual dysfunction AND obstetric events.Selection CriteriaWe included original, comparative studies, reported in English, that used validated questionnaires and the ICS/IUGA terminology for sexual dysfunction, dyspareunia and vaginal dryness.Data Collection and AnalysisWe assessed the quality and the risk of bias of the included studies with the Newcastle–Ottawa scale. We extracted the reported data and we performed random‐effects meta‐analysis to obtain the summary odds ratios (ORs) with 95% confidence intervals (95% CIs). Heterogeneity across studies was assessed using the I2 statistic.Main ResultsAnal sphincter injury was associated with increased odds for both sexual dysfunction (OR 3.00, 95%CI 1.28–7.03) and dyspareunia (OR 1.92, 95% CI 1.47–2.52). Episiotomy was associated with dyspareunia (OR 1.64, 95% CI 1.25–2.14), but not with sexual dysfunction (OR 1.90, 95% CI 0.94–3.84). Compared with spontaneous birth, caesarean section reduced the odds for dyspareunia (OR 0.68, 95% CI 0.54–0.86) but not for sexual dysfunction (OR 1.14, 95% CI 0.89–1.46). Instrumental vaginal birth increased the odds for sexual dysfunction (OR 1.70, 95% CI 1.05–2.76), yet no difference was found for dyspareunia (OR 1.82, 95% CI 0.88–3.75). One study of low quality reported on vaginal dryness and found no association with obstetric events.ConclusionsPerineal trauma, rather than mode of birth, increases the odds for sexual dysfunction in the first year after childbirth.Tweetable AbstractPerineal trauma, rather than mode of birth, correlates with sexual dysfunction and dyspareunia postpartum. #dyspareunia #OASI #episiotomy
Crime, quarantine, and the U.S. coronavirus pandemic
Authors: Lopez Ernesto , Rosenfeld Richard 
Published: September 2021

AbstractResearch SummaryPriorresearch has produced varied results regarding the impact of the coronavirus pandemic on crime rates, depending on the offenses and time periods under investigation. The current study of weekly offense rates in large U.S. cities is based on a longer time period, a greater number of offenses than prior research, and a varying number of cities for each offense (max = 28, min = 13, md = 20). We find that weekly property crime and drug offense rates, averaged across the cities, fell during the pandemic. An exception is motor vehicle theft, which trended upward after pandemic‐related population restrictions were instituted in March 2020. Robbery rates also declined immediately after the pandemic began. Average weekly homicide, aggravated assault, and gun assault rates did not exhibit statistically significant increases after March. Beginning in June 2020, however, significant increases in these offenses were detected, followed by declines in the late summer and fall. Fixed‐effects regression analyses disclose significant decreases in aggravated assault, robbery, and larceny rates associated with reduced residential mobility during the pandemic. These results support the routine activity hypothesis that the dispersion of activity away from households increases crime rates. The results for the other offenses are less supportive.Policy ImplicationsQuarantines and lockdowns, although necessary to reduce contagious illness, are not desirable crime‐control devices. An object lesson of the coronavirus pandemic is to redouble effective crime reduction strategies and improve police–community relations without confining people to their homes.

AbstractIntramuscular fat (IMF) is an important factor affecting meat quality, but lipid and metabolic profiles of donkey meat remain unclear. The present study was conducted to investigate lipid characteristics in different parts of Dezhou donkey using lipidomics. The results show that IMF was more abundant in longissimus dorsi muscle (LDM) than rump muscle (RM) and hamstring muscle (HM), and mainly composed of triglycerides (TGs) rich in saturated fatty acid (SFAs) and monounsaturated fatty acid (MUFAs). A total of 1143 lipids belonging to 14 subclasses were identified in donkey meat, of which 73 lipids (23 upregulated and 50 downregulated) including glycerolipids (GLs), glycerophospholipids (GPs) and sphingolipids (SPs) were significantly different and are therefore potential biomarkers in LDM versus RM versus HM analyses (variable importance in projection >1, p < 0.05). Notably, 21 TGs upregulated in LDM were rich in MUFAs at sn‐1 and SFAs at 2 and 3 positions of TG. Donkey muscle accumulated far more SFAs at the sn‐3 position of TG, while more SFAs were present at the sn‐1 positions of phosphatidylcholine (PC) and phosphatidylethanolamine (PE), and the percentages of SFAs at the three positions in TG, PC, and PE in the LDM group were much higher. The abundance of MUFAs at the sn‐2 positions of TG, PC, and PE was significantly greater than in sn‐1 or 3 positions, and the percentages of 18:1n‐9 at the sn‐1 and 2 position of TGs in LDM were significantly higher than in RM and HM groups. Polyunsaturated fatty acids (e.g.,18:2n‐6, 18:3n‐3, and 20:4n‐6) tended to occur at the sn‐1 position in TG, but at the sn‐2 position in PC and PE. Significantly differential lipids were mainly enriched in GP, GL, and SP pathways, all considered key pathways for regulating IMF. The results reveal the components, structures and metabolic pathways of lipid molecules in donkey meat, and provide novel insight into the development of donkey meat products and accurate regulation of IMF.Practical ApplicationIntramuscular fat (IMF) is an important factor affecting meat quality, which is directly related to meat flavor, juiciness, and tenderness, but lipid and metabolic profiles of IMF remain unclear. The current results provide basic information for the development of donkey meat products, and broaden our understanding of the regulation of IMF.
