Does political skill promote knowledge hiding? An impression management perspective
Authors: Chen Lifan , Zhang Shanshan , Hu Xiaoli , Liu Shengming , Lan Rujia 
Published: March 2024

Purpose
As a counterproductive interpersonal work behavior, knowledge hiding inhibits team creativity, hampers collaboration and ultimately has a detrimental impact on organizational performance. Drawing upon the impression management perspective. This study aims to investigate how and when employees’ political skill affects their knowledge-hiding behavior in real work contexts.

Design/methodology/approach
The authors tested the hypotheses using data gathered from 266 employees in China using a time-lagged research design.

Findings
The results indicate that political skill positively influences knowledge hiding through the supplication strategy. Moreover, the positive effect of political skill on this strategy is stronger under higher levels of competition.

Research limitations/implications
A cross-sectional design and the use of self-report questionnaires are the limitations of this study.

Originality/value
The authors contribute to the literature on the emergence of knowledge hiding by identifying an impression management perspective. The authors also contribute to the literature on political skill by exploring the potential negative effects of political skill in the interpersonal interaction. Moreover, the authors enrich the understanding of the literature in competitive climate by introducing the impression management theory and exploring its influence on knowledge floating.
Relations of subordination: Canada’s first indigenous dean of a law school
Authors: Grant James D. 
Published: March 2024

PurposeThe goal was emancipatory, to characterise and dislodge oppressive management practices, to allow for the possibility of seeking an alternative organisational construction free of postcolonial/subaltern subordination and discrimination in a local, well-documented narrative.Design/methodology/approachThe study was informed by a postcolonial/subaltern perspective and drew on the employment experience of an Aboriginal woman, Canada’s first Indigenous Dean of a law school. The researcher employed a combination of case study and critical discourse analysis with the aim of advancing rich analyses of the complex workings of power and privilege in sustaining Western, postcolonial relations.FindingsThe study made several conclusions: first, that the institution, a medium-sized Canadian university, carefully controlled the Indigenous subaltern to remake her to be palatable to Western sensibilities. Second, the effect of this control was to assimilate her, to subordinate her Indigeneity and to civilise in a manner analogous to the purpose of Indian residential schools. Third, that rather than management’s action being rational and neutral, focused on goal attainment, efficiency and effectiveness, it was an implicit moral judgement based on her race and an opportunity to exploit her value as a means for the university’s growth and status.Originality/valueThrough a postcolonial/subaltern perspective, this study demonstrated how management practices reproduced barriers to the participation of an Indigenous woman and the First Nations community that an organisation was intended to serve. The study demonstrated how a Western perspective – that of a university’s administration, faculty and staff – was privileged, or taken for granted, and the Indigenous perspective subordinated, as the university remained committed to the dispossession of Indigenous knowledge and values.

AbstractRheumatoid arthritis (RA) is a chronic autoimmune disease that causes inflammation and pain, which can lead to the loss of normal joint function. Although the exact cause of the disease is not yet fully understood, both environmental factors and genetics may play a role in its development. Moreover, research suggests microbiota contributes to the onset and progression of RA. People with RA show higher quantities of bacteria such as Porphyromonas gingivalis, Aggregatibacter actinomycetemcomitans, Prevotella copri, Proteus mirabilis, and Lactobacillus salivarius compared to healthy individuals. Conversely, studies propose that Lactobacillus casei, a probiotic bacterium with immunomodulatory properties, has beneficial effects for RA in murine and human models. Therefore, this work reviews the potential role of the gut microbiota in the development of RA and explores the feasibility of using probiotic bacteria as a supplementary treatment for this disease.

Published: March 2024

AbstractIntroductionTreatment of post lung‐transplant airway complications is challenging, and treatment with conventional airway stents is associated with adverse events. More recently, biodegradable airway stents (BDS) have been introduced and may be used to reduce these adverse events. In this study we explore the feasibility of treatment with BDS post lung transplant.MethodsAll patients treated with BDS in The Netherlands were included in this retrospective multicenter study. Feasibility, life span of the stent, occurrence of adverse events, and evolution of lung function were evaluated.ResultsTwelve patients (six malacia and six stenosis) received a total of 57 BDS, ranging from 1 to 10 BDS per patient. Six patients had been pretreated with conventional airway stents. Median stent life span was 112 days (range 66–202). No adverse events occurred during stent placement. In 5 out of 57 stent placements, a single additional bronchoscopy was necessary because of mucus accumulation (n = 4) or excessive granulation tissue (n = 1). All stent naïve patients became airway stent independent after treatment; all patients pretreated with conventional airway stents were still airway stent dependent at the end of follow up.ConclusionTreatment with BDS is safe and feasible. Adverse events were mild and easily treatable. All patients with initial treatment with BDS were airway stent independent at the end of follow up with a median treatment of 4 BDS.

AbstractIntroductionLittle is known about very early atrial fibrillation (AF) ablation after first AF detection.MethodsWe evaluated patients with AF ablation <4 months from newly diagnosed paroxysmal AF (NEWPaAF) and newly diagnosed persistent AF (NEWPeAF). We compared the two patient populations and compared ablation outcomes to those undergoing later ablation.ResultsAblation was done <4 months from AF diagnosis in 353 patients (135 = paroxysmal, 218 = persistent). Early ablation outcome was best for NEWPaAF versus NEWPeAF for initial (p = 0.030) but not final (p = 0.102) ablation. Despite recent AF diagnosis in both groups, they were clinically quite different. NEWPaAF patients were younger (64.3 ± 13.0 vs. 67.3 ± 10.9, p = 0.0020), failed fewer drugs (0.39 vs. 0.60, p = 0.007), had smaller LA size (4.12 ± 0.58 vs. 4.48 ± 0.59 cm, p < 0.0001), lower BMI (28.8 ± 5.0 vs. 30.3 ± 6.0, p = 0.016), and less CAD (3.7% vs. 11.5%, p = 0.007), cardiomyopathies (2.2% vs. 22.9%, p = 0.0001), hypertension (46.7% vs. 67.4%, p < 0.0001), diabetes (8.1% vs. 17.4%, p = 0.011) and sleep apnea (20.0% vs. 30.3%, p = 0.031). For NEWPaAF, early ablation AF‐free outcome was no better than later ablation (p = 0.314). For NEWPeAF, AF‐free outcomes were better for early ablation than later ablation (p < 0.0001). Delaying ablation allowed more strokes/TIAs in both AF types (paroxysmal p = 0.014, persistent p < 0.0001).ConclusionsPatients presenting for early ablation after newly diagnosed persistent AF have more pre‐existing comorbidities and worse initial ablation outcomes than patients with NEWPaAF. For NEWPaAF, there was no advantage to early ablation, as long as the AF remained paroxysmal. For NEWPeAF, early ablation gave better outcomes than later ablation and they should undergo early ablation. For both AF types, waiting was associated with more neurologic events, suggesting all patients should consider earlier ablation.

AbstractAimTo compare connective tissue graft (CTG) with collagen matrix (CMX) in terms of increase in buccal soft tissue profile (BSP) when applied at single implant sites.Materials and MethodsPatients with a single tooth gap in the anterior maxilla and horizontal mucosa defect were enrolled in a multi‐centre randomized controlled trial. All were fully healed sites with a bucco‐palatal bone dimension of at least 6 mm, and received an immediately restored single implant using a full digital workflow. Patients were randomly allocated to the control (CTG) or test group (CMX: Geistlich Fibro‐Gide, Geistlich Pharma AG, Wolhusen, Switzerland) to increase buccal soft tissue thickness. Primary endpoints were increase in BSP at T1 (immediately postop), T2 (3 months), T3 (1 year) and T4 (3 years) based on superimposed digital surface models. Secondary endpoints included patient‐reported, clinical and aesthetic outcomes.ResultsThirty patients were included per group (control group: 15 males, 15 females, mean age 50.1 years; test group: 14 males, 16 females, mean age 48.2 years) and 50 could be re‐examined at T4. The changes in BSP over time were significantly different between the groups (p < .001). At T4, the estimated mean increase in BSP amounted to 0.83 mm (95% confidence interval [CI]: 0.58–1.08) in the control group and 0.48 mm (95% CI: 0.22–0.73) in the test group. The estimated mean difference of 0.35 mm (95% CI: 0.06–0.65) in favour of the control group was significant (p = .021). No significant differences between the groups could be observed in terms of patients' aesthetic satisfaction (p = .563), probing depth (p = .286), plaque (p = .676), bleeding on probing (p = .732), midfacial recession (p = .667), Pink Esthetic Score (p = .366) and Mucosal Scarring Index (p = .438). However, CMX resulted in significantly more marginal bone loss (−0.43 mm; 95% CI: −0.77 to −0.09; p = .015) than CTG.ConclusionsCTG was more effective in increasing buccal soft tissue profile and resulted in less marginal bone loss than CMX. Therefore, CTG remains the gold standard to increase soft tissue thickness at implant sites. Clinical Trial registration: This study was registered in ClinicalTrials.gov (NCT04210596).
Altered hippocampal doublecortin expression in Parkinson's disease

Published: March 2024

AbstractParkinson's disease (PD) is a complex neurodegenerative disorder characterized by motor and non‐motor symptoms. Motor symptoms include bradykinesia, resting tremors, muscular rigidity, and postural instability, while non‐motor symptoms include cognitive impairments, mood disturbances, sleep disturbances, autonomic dysfunction, and sensory abnormalities. Some of these symptoms may be influenced by the proper hippocampus functioning, including adult neurogenesis. Doublecortin (DCX) is a microtubule‐associated protein that plays a pivotal role in the development and differentiation of migrating neurons. This study utilized postmortem human brain tissue of PD and age‐matched control individuals to investigate DCX expression in the context of adult hippocampal neurogenesis. Our findings demonstrate a significant reduction in the number of DCX‐expressing cells within the subgranular zone (SGZ), as well as a decrease in the nuclear area of these DCX‐positive cells in postmortem brain tissue obtained from PD cases, suggesting an impairment in the adult hippocampal neurogenesis. Additionally, we found that the nuclear area of DCX‐positive cells correlates with pH levels. In summary, we provide evidence supporting that the process of hippocampal adult neurogenesis is likely to be compromised in PD patients before cognitive dysfunction, shedding light on potential mechanisms contributing to the neuropsychiatric symptoms observed in affected individuals. Understanding these mechanisms may offer novel insights into the pathophysiology of PD and possible therapeutic avenues.image

Published: March 2024

AbstractPurposeThe objective of this retrospective study was to evaluate the effect of the interproximal contour of single external hexagon implant restorations on the prevalence of peri‐implantitis.Material and MethodsRecords of 96 patients and 148 external hexagon (EH) implants with time in function ranging from 1 to 17 years were included in the study. The most recent clinical and radiographic data were collected from records and the prevalence of peri‐implantitis was defined according to the 2017 World Workshop on the Classification of Periodontal and Peri‐implant Diseases and Conditions. Marginal bone level (MBL), emergence angle (EA), emergence profile (EP), and crown/implant platform horizontal ratio (CIHR) were obtained from periapical radiographs. Dichotomous variables at the patient‐ and implant level were compared with association tests. Mann‐Whitney U‐Test was performed to compare continuous quantitative values between the studied groups. Binomial logistic regression was conducted to identify risk indicators associated with the peri‐implantitis event at the patient‐ and implant level, with the significance level set at 5% for all tests.ResultsNineteen patients (19.2%) and 24 implants (16.2%) with a mean time in function of 5.0 ± 4.7 years were classified as having peri‐implantitis. No statistically significant differences concerning gender, mean age, implant location in the jaw, or time in function were observed between patients with or without peri‐implantitis (p > 0.05). Of 24 implants with peri‐implantitis 10 (41.7%) displayed EA ≤ 30° (16.4%) while 14 (58.3%) presented EA > 30° with no statistical difference between the groups (p > 0.05). No statistically significant associations were identified between EA, EP, or CIHR and the prevalence of peri‐implantitis.ConclusionThe findings seem to indicate that the EA, EP, and CIHR of single restorations over external hexagon implants are not associated with the presence of peri‐implantitis. However, prospective studies with larger samples are required to better ascertain such an association in the long term.

AbstractA team of literacy, science, and theatre educators have been working to engage children in an urban public school system in the United States through embodied performances, where students embody and dramatise science ideas. This study focuses on one fourth‐grade classroom when instruction was done remotely due to Covid‐19. Children in the class were asked to compose videos of themselves acting out and/or exploring science phenomena and concepts, and we analysed the affordances of these multimodal compositions. We situate the need for this study in claims from the Next Generation Science Standards that literacy skills are necessary to build and communicate science knowledge. In doing so, we center social semiotics perspectives that conceive of composition broadly as production‐oriented processes drawing from various semiotic resources. The multimodal compositions in Mr. M's science class included both primarily embodied compositions and primarily digital compositions, and we elaborate on one focal example of each in the findings. Intertwined affordances of the focal children and their classmates' multimodal science compositions include opportunities to creatively engage with and negotiate science ideas, to draw from personal and social knowledge during meaning‐making, and to intentionally make rhetorical choices.
Modeling prevention behaviors during the COVID‐19 pandemic using Bayesian belief networks and protection motivation theory

Published: March 2024

AbstractPrevention behaviors are important in mitigating the transmission of COVID‐19. The protection motivation theory (PMT) links perceptions of risk and coping ability with the act of adopting prevention behaviors. The goal of this research is to test the application of the PMT in predicting adoption of prevention behaviors during the COVID‐19 pandemic. Two research objectives are achieved to explore motivating factors for adopting prevention behaviors. (1) The first objective is to identify variables that are strong predictors of prevention behavior adoption. A data‐driven approach is used to train Bayesian belief network (BBN) models using results of a survey of participants reporting risk perceptions and prevention behaviors during the COVID‐19 pandemic. A large set of models are generated and analyzed to identify significant variables. (2) The second objective is to develop models based on the PMT to predict prevention behaviors. BBN models that predict prevention behaviors were developed using two approaches. In the first approach, a data‐driven methodology trains models using survey data alone. In the second approach, expert knowledge is used to develop the structure of the BBN using PMT constructs. Results demonstrate that trust and experience with COVID‐19 were important predictors for prevention measure adoption. Models that were developed using the PMT confirm relationships between coping appraisal, threat appraisal, and protective behaviors. Data‐driven and PMT‐based models perform similarly well, confirming the use of PMT in this context. Predicting adoption of social distancing behaviors provides insight for developing policies during pandemics.

ObjectiveWe aimed to define the epidemiology of COVID-19 outbreaks in aged care facilities (ACFs) during the postvaccine period, including vaccine effectiveness (VE) for this high-risk group.DesignSystematic review and meta-analysis.Data sourcesOvid Medline, Ovid Embase, Scopus, Web of Science and Cochrane databases were searched through 1 September 2023.Eligibility criteriaAny original observational studies and trials reporting data on COVID-19 outbreaks among the partially/fully vaccinated residents from ACFs during or after the worldwide implementation of vaccine roll-out.Data extraction and synthesisWe estimated the attack rate, case fatality rate, mortality rate and VE during postvaccine period. Random effect model was adopted for meta-analysis. Quality assessment on all included studies was performed using the Meta Quality Appraisal Tool.Results38 articles were included from 12 countries reporting 79 outbreaks with 1708 confirmed cases of COVID-19 from 78 ACFs. The pooled attack rate was 28% (95% CI 20% to 37%) among the fully vaccinated residents. Two-thirds (62.5%) of the index cases were unvaccinated healthcare professionals (eg, physicians, nurses) and caregivers. Unvaccinated residents had a significantly higher rates (12%) (95% CI 7% to 19%) of mortality compared with the vaccinated residents (2%) (95% CI% 1 to 4%) and the post-COVID-19 vaccine estimates for case fatality rate (13% vs 23%) and hospitalisation rate (17% vs 37%) were substantially lower. VE in preventing disease among residents in ACFs was 73% (95% CI 49% to 86). Overall, the included studies were heterogeneous in nature, however, the risk of bias was low to moderate.ConclusionsOur study reaffirmed the impact of vaccination as a key public health measure to minimise the burden of COVID-19 in ACFs. Facilities with higher crowding indexes should be prioritised for vaccination and should advocate for higher vaccination targets among staff and residents as a critical intervention strategy to minimise disease burden in this vulnerable population.

Published: March 2024

ObjectivesTo understand the extent to which various demographic and social determinants predict mental health status and their relative hierarchy of predictive power in order to prioritise and develop population-based preventative approaches.DesignCross-sectional analysis of survey data.SettingInternet-based survey from 32 countries across North America, Europe, Latin America, Middle East and North Africa, Sub-Saharan Africa, South Asia and Australia, collected between April 2020 and December 2021.Participants270 000 adults aged 18–85+ years who participated in the Global Mind Project.Outcome measuresWe used 120+ demographic and social determinants to predict aggregate mental health status and scores of individuals (mental health quotient (MHQ)) and determine their relative predictive influence using various machine learning models including gradient boosting and random forest classification for various demographic stratifications by age, gender, geographical region and language. Outcomes reported include model performance metrics of accuracy, precision, recall, F1 scores and importance of individual factors determined by reduction in the squared error attributable to that factor.ResultsAcross all demographic classification models, 80% of those with negative MHQs were correctly identified, while regression models predicted specific MHQ scores within ±15% of the position on the scale. Predictions were higher for older ages (0.9+ accuracy, 0.9+ F1 Score; 65+ years) and poorer for younger ages (0.68 accuracy, 0.68 F1 Score; 18–24 years). Across all age groups, genders, regions and language groups, lack of social interaction and sufficient sleep were several times more important than all other factors. For younger ages (18–24 years), other highly predictive factors included cyberbullying and sexual abuse while not being able to work was high for ages 45–54 years.ConclusionSocial determinants of traumas, adversities and lifestyle can account for 60%–90% of mental health challenges. However, additional factors are at play, particularly for younger ages, that are not included in these data and need further investigation.
