Knowledge systems, behaviours and organizational tasks for hospital effectiveness: mixed effects on quality of care
Authors: Gonçalves Tiago Rodrigues , Curado Carla 
Published: June 2024

PurposeThe healthcare sector relies on knowledge management systems to improve knowledge flows and effectively capture, leverage and share knowledge with several organizational stakeholders. However, knowledge as a resource represents a social construct that involves additional managerial complexities and challenges, including undesirable knowledge behaviours. The aim of the current study is to provide insight on how knowledge management systems, knowledge hoarding, knowledge hiding and task conflict shape the quality of care provided by hospitals. We propose and test an original revealing model.Design/methodology/approachWe follow a quantitative approach to address the structural relationship between variables using a combination of factor analysis and multiple regression analysis. The model is tested adopting a structural equation modelling approach and using survey data conducted to 318 healthcare professionals working in Portuguese hospitals.FindingsThe main findings suggest that knowledge hiding is positively related to task conflict in hospitals, and task conflict negatively influences quality of care. Knowledge management systems directly and indirectly (via knowledge hoarding) promote quality of care. Moreover, knowledge management systems also mitigate the negative influence of task conflict over quality of care. We propose a final corollary on the relevant role of HRM as the backstage for the model.Practical implicationsOur research offers a novel insight into an overlap of organizational behaviour and healthcare management research. It provides an original framework on knowledge management systems, counterproductive knowledge behaviours and task conflict in hospital settings.Originality/valueOur research offers a novel insight into an overlap of organizational behaviour and healthcare management research. It provides an original framework on knowledge management systems, counterproductive knowledge behaviours and task conflict in hospital settings.

Abstract

Forest dynamics are driven by micro‐disturbances leading to gap formation. Root rot pathogens can cause mortality to adult trees, which die forming gaps. However, little is known about the biotic and abiotic factors that govern gap creation and expansion such as tree infection or drought resilience, and what are the consequences for nutrient cycling and soil microbiota.

We studied the dynamics of gaps created by Heterobasidion abietinum in mountain silver fir (Abies alba) forests from the Spanish Central Pyrenees. Tree‐ring width information was used to evaluate growth patterns of trees located within and at the edge of gaps and under closed canopy conditions. We analysed soil nutrient content and microbial structure at different positions with respect to the gap. Soil fungal community was also characterized by sequencing the ITS2 region.

Gaps created by H. abietinum ranged 582–1072 m2 and gathered large amounts of standing and laying dead wood biomass amounting to up to 500 m3 ha−1 of coarse woody debris. This indicates that tree mortality had been occurring over decades, and it was preceded by a long‐term growth decline and impaired drought resilience. Root rot affected trees beyond the current limit of the gaps leading to growth decline, preventing canopy closure and allowing the release of suppressed trees within the gap. Gap formation did neither affect soil fertility nor fungal and bacterial biomass and diversity, but long‐distance ectomycorrhizal fungi were more abundant within gaps.

Synthesis. Root rot pathogens play key ecological roles in forest dynamics at fine spatial scale. Heterobasidion abietinum infection, and its interaction with drought, creates and expands gaps by killing large trees and preventing surrounding trees from closing the gap. The survival of mycorrhizal networks to gap formation suggests little disruption of soil fungal communities.

Published: July 2024

AbstractWe examine the association between loan portfolio concentration, competition and stock price crash risk in the US banking industry. We find that during economic downturns, banks with poorly diversified loan portfolios that operate in competitive markets are more likely to crash. Importantly, we show that this link is channelled through aggressive earnings management and ambiguous annual reports. Therefore, managerial ambiguity can serve as an early warning signal of information obfuscation, which can eventually lead to stock price crashes. As a quasi‐natural experiment, we use the passage of the Economic Growth, Regulatory Relief, and Consumer Protection Act in 2018. This policy lowered the regulatory requirements and oversight for a specific group of large banks. The results of a difference‐in‐differences analysis support our baseline findings and add to the ongoing debate on the roots of the 2023 banking crisis. Therefore, our findings can be informative to market participants, regulators and policy makers.

AbstractObjectiveTo investigate the positive rate of late‐onset gestational diabetes mellitus (GDM) by additional fasting blood glucose (FBG) screening at 32–34 gestational weeks (GW) and analyse the perinatal outcomes of late‐onset GDM after standard treatment.DesignAn Prospective cohort study.SettingSingle centre in China.Population1130 singleton pregnancies with negative GDM screening in their first and second trimester.MethodsAdditional FBG testing was performed at 32–34 GW. Pregnancies with FBG ≥5.1 mmol/L were diagnosed as GDM and received standardized treatment. Perinatal outcomes were collected and compared.Main Outcome MeasuresDiagnosis of late‐onset GDM, obstetric and neonatal outcomes.Results6.3% (71/1130) of participants had FBG values ≥5.1 mmol/L and were diagnosed with late‐onset GDM. Sixty‐five (91.5%) were treated by dietary therapy and 6 (8.5%) by insulin therapy. The perinatal outcomes of full‐term delivery were compared. The incidence of macrosomia (22.7% vs. 5.1%, adjusted odds ratio (aOR) 5.51, 95% confidence interval (CI) 1.83–16.61, p = 0.002) and NICU transferring (18.3% vs. 10.1%, aOR 1.94, 95% CI 1.01–3.74, p = 0.046) was significantly higher in late‐onset GDM group than that in FBG <5.1 mmol/L group. Elevated FBG was associated with overweight or obesity during pregnancy (54.9% vs. 34.9%, OR 2.27, 95% CI 1.40–3.68, p = 0.001).Conclusions6.3% of singleton pregnancies with normal GDM screening results in the first and second trimester were found to have late‐onset GDM by additional FBG screening at 32–34 GW, and their risk of macrosomia during a full‐term pregnancy remains significantly higher after standard treatment.

Published: June 2024

AbstractAutomobile paint chips are a crucial piece of trace evidence for forensic investigators. This is because automotive paints are composed of multiple layers, including the primer, basecoat, and clearcoat, each of which has its own chemical composition that can vary by vehicle make, model, year, and manufacturing plant. Thus, Fourier‐transform infrared (FTIR) spectral databases for automobile paint systems have been established to aid law enforcement in, for example, narrowing search parameters for a suspect's vehicle. Recently, car manufacturers have implemented primers on plastic substrates that are much thinner (~5 μm) than those on metal substrates, making it more difficult to manually separate for analyses. Here, we evaluated FTIR microspectroscopy (μ‐FTIR) and optical photothermal infrared spectroscopy (O‐PTIR) to chemically image cross sections of paint chips without manually separating the layers. For μ‐FTIR, transmission and transflection modes provided the highest quality spectra compared to reflection and μ‐ATR analyses. Point analysis was preferable to chemical imaging, as peaks were identified in the point (MCT) detector's lower spectral range that was below the imaging (FPA) detector's cutoff, such as those associated with titanium dioxide. Reduced spectral range can lead to a similar issue in O‐PTIR analyses depending on instrument configuration. However, its complementary Raman spectra showed strong titanium dioxide peaks, providing an alternate means of identification. Both techniques are likely to become more relevant as they are non‐destructive and avoid manual separation of the layers. O‐PTIR is particularly well‐suited for analysis of the thin primer layer due to its superior spatial resolution.

BackgroundDuring the COVID‐19 pandemic, mitigation measures were associated with a reduction in preterm birth rates; while not clearly proven, this observation has sparked significant interest.AimTo understand the cause of this reduction by exploring the characteristics of preterm birth cohorts.Material and methodsWe performed a retrospective cohort study where we compared women who delivered preterm in three Melbourne maternity hospitals and conceived between November 2019 and February 2020 (mitigation measures‐exposed cohort) to women who delivered preterm and conceived between November 2018 and February 2019 (non‐exposed cohort). We compared maternal characteristics, pregnancy complications, antenatal interventions, intrapartum care, and indications for delivery.ResultsIn the exposed cohort, 252/3129 women delivered preterm (8.1%), vs 298/3154 (9.4%) in the non‐exposed cohort (odds ratio (OR) 0.84, 95% CI 0.70–1.00, P = 0.051). The baseline characteristic of two cohorts were comparable. Rates of spontaneous preterm labour (sPTL) without preterm pre‐labour rupture of membranes (PPROM) were lower in the exposed cohort (13.1% vs 24.2%, OR 0.47, P = 0.001) while PPROM occurred more often (48.0% vs 35.6%, OR 1.67, P = 0.003). With a non‐statistically significant prolongation of pregnancy in the cohort exposed to mitigation measures for both sPTL without PPROM (35.4 vs 34.9 weeks, P = 0.703) and PPROM (35.6 vs 34.9 weeks, P = 0.184). The rate of spontaneous labour after PPROM was higher in the exposed cohort compared to the non‐exposed cohort (40.1% vs 24.1%, OR 2.09, P < 0.001).ConclusionThe reduction in preterm delivery during mitigation measures may have been driven by a reduction in spontaneous labour without PPROM, which seemed to result in more PPROM later in pregnancy.
When and how is abusive supervision enacted toward competent subordinates? The role of supervisors' power loss concern and downward envy

Published: July 2024

AbstractIn general, supervisor abuse is directed toward low‐performing subordinates. Similarly, envy is typically felt by professionals in lower ranks toward those in higher positions. By contrast, this study investigates the counterintuitive relationship between the abusive behavior of envious leaders toward their competent subordinates. Specifically, we argue that supervisors become envious of competent employees when they are anxious about losing power. Multisource, time‐lagged data collected from dyads (198 supervisors and 198 subordinates) in Pakistan‐based organizations support the proposed hypotheses. The findings show a positive relationship between perceptions of subordinate competence, supervisors' downward envy, and abusive supervision. In addition, the relationship between perceived subordinates' competence and supervisors' envy is strong when supervisors' power loss concerns are high. This study provides useful theoretical and practical insights for human resource managers dealing with unethical workplace behavior.

AbstractUnder the recently adopted Kunming‐Montreal Global Biodiversity Framework, 196 Parties committed to reporting the status of genetic diversity for all species. To facilitate reporting, three genetic diversity indicators were developed, two of which focus on processes contributing to genetic diversity conservation: maintaining genetically distinct populations and ensuring populations are large enough to maintain genetic diversity. The major advantage of these indicators is that they can be estimated with or without DNA‐based data. However, demonstrating their feasibility requires addressing the methodological challenges of using data gathered from diverse sources, across diverse taxonomic groups, and for countries of varying socio‐economic status and biodiversity levels. Here, we assess the genetic indicators for 919 taxa, representing 5271 populations across nine countries, including megadiverse countries and developing economies. Eighty‐three percent of the taxa assessed had data available to calculate at least one indicator. Our results show that although the majority of species maintain most populations, 58% of species have populations too small to maintain genetic diversity. Moreover, genetic indicator values suggest that IUCN Red List status and other initiatives fail to assess genetic status, highlighting the critical importance of genetic indicators.

AbstractObjectivesA surgical “treatment gap” in pediatric epilepsy persists despite the demonstrated safety and effectiveness of surgery. For this reason, the national surgical landscape should be investigated such that an updated assessment may more appropriately guide health care efforts.MethodsIn our retrospective cross‐sectional observational study, the National Inpatient Sample (NIS) database was queried for individuals 0 to <18 years of age who had an International Classification of Diseases (ICD) code for drug‐resistant epilepsy (DRE). This cohort was then split into a medical group and a surgical group. The former was defined by ICD codes for ‐DRE without an accompanying surgical code, and the latter was defined by DRE and one of the following epilepsy surgeries: any open surgery; laser interstitial thermal therapy (LITT); vagus nerve stimulation; or responsive neurostimulation (RNS) from 1998 to 2020. Demographic variables of age, gender, race, insurance type, hospital charge, and hospital characteristics were analyzed between surgical options. Continuous variables were analyzed with weight‐adjusted quantile regression analysis, and categorical variables were analyzed by weight‐adjusted counts with percentages and compared with weight‐adjusted chi‐square test results.ResultsThese data indicate an increase in epilepsy surgeries over a 22‐year period, primarily due to a statistically significant increase in open surgery and a non‐significant increase in minimally invasive techniques, such as LITT and RNS. There are significant differences in age, race, gender, insurance type, median household income, Elixhauser index, hospital setting, and size between the medical and surgical groups, as well as the procedure performed.SignificanceAn increase in open surgery and minimally invasive surgeries (LITT and RNS) account for the overall rise in pediatric epilepsy surgery over the last 22 years. A positive inflection point in open surgery is seen in 2005. Socioeconomic disparities exist between medical and surgical groups. Patient and hospital sociodemographics show significant differences between the procedure performed. Further efforts are required to close the surgical “treatment gap.”

AbstractAimThe osteogenic potential of new premixed calcium‐silicate‐containing bioceramic sealers (Ca‐Si sealers) was tested with porcine vascular wall‐mesenchymal stem cells (pVW‐MSCs).MethodologyTwo Ca‐Si‐containing sealers: Ceraseal (MetaBiomed, Cheong‐si, South Korea) and AH Plus Bioceramic (Maruchi, Wonju‐si, South Korea), and an epoxy resin sealer (AH Plus; Dentsply, Konstanz, Germany) as a control, were prepared according to the manufacturers' indications. All samples were allowed to set for 100% of their setting time in a sterile humid cabinet at 37°C and 95% relative humidity. pVW‐MSC seeding efficiency and osteogenic differentiation were analysed as marker of gene/protein expression for up to 12 days. Mineralization assay and immunofluorescence staining were performed and evaluated over a period of 21 days. Statistical analyses were conducted using one‐way analysis of variance (p < .05). Additional samples were prepared and stored under the same conditions and inspected using an environmental scanning electron microscope equipped with an energy dispersive X‐ray spectroscopy system.ResultsSignificantly higher cell seeding efficiency (p < .05) was observed for both Ca‐Si sealers from day 8. pVW‐MSCs showed a significant shift towards the osteogenic lineage only when seeded in contact with Ca‐Si sealers. Gene expression of osteopontin was upregulated significantly. Collagen I and osteocalcin were clearly expressed by cells in contact with Ca‐Si sealers. Mineralization granules were observed in Alizarin red assays and confocal laser scanning microscopy analysis of both Ca‐Si sealers. No gene expression or granule mineralization were observed on the epoxy resin sealer.ConclusionsPremixed Ca‐Si sealers displayed a higher potential for osteogenic activity on pVW‐MSCs. Epoxy resin sealer was unable to induce any osteogenic activity. The properties of both Ca‐Si sealers suggest their potential as osteoinductive platforms for vascular MSCs in periapical bone.

AbstractThe Aurivillius compounds in the Bi2O3–Fe2O3–TiO2 system, combining ferroelectric, semiconducting, and ferromagnetic properties, have attracted particular interest. Formation kinetics and thermodynamic stability are the fundamental knowledge needed for modeling and predicting the temporal microstructure and property evolution during materials processing but have not yet been addressed by quantitative experimental measurement. This article focuses on the Bin+1Fen–3Ti3O3n+3 Aurivillius compounds on the Bi4Ti3O12–BiFeO3 tie‐line to elucidate the mechanisms and thermodynamic controls responsible for phase formation of compounds with various perovskite‐like layers. Five high‐purity Aurivillius compounds Bi4Ti3O12, Bi5FeTi3O15, Bi6Fe2Ti3O18, Bi7Fe3Ti3O21, and Bi8Fe4Ti3O24 with integer n = 3–7 values were synthesized and their phase transformation properties and enthalpies of formation were studied by X‐ray diffraction in situ, high temperature differential scanning calorimetry, and high temperature oxide melt solution calorimetry. Thermodynamic stability of the compounds decreases with increasing n, and formation kinetics gradually slow down, demonstrating the inherent difficulty to synthesize pure Aurivillius compounds with n larger than 8. This difficulty was confirmed by an impurity phase coexisting with Bi9Fe5Ti3O27.
Oxidation under stress of SiC‐based fibers at intermediate temperature and ambient air

Published: June 2024

AbstractIf the temperature and environment effects on the oxidation of SiC fibers have been extensively documented, the impact of external stresses (stress‐oxidation coupling effect) remains questioned. Therefore, interrupted static fatigue tests were conducted on filaments. Surviving specimens (>60%) were subsequently tensile tested and fracture surfaces recovered for analysis. The external stress was found to have no impact on the oxidation regime (linear or parabolic) nor on its rate, which is comparable to literature data. As long as the slow crack growth (SCG) incubates (negligible growth rate), the oxidation was shown to govern the embrittlement. Fracture surface analysis revealed tensile residual stresses, attributed to a wedge effect when specimens were unloaded. Rare tests (<2%) were interrupted while the crack had significantly grown highlighting the successive crack fronts. Sources of residual stresses and differences between fiber types (flaw position inducing a bias on lifetime prediction) are discussed. In these circumstances, a coupling effect between the oxidation embrittlement and the SCG could be assumed for moderate stress levels, which is pertinent for most of ceramic matrix composite applications.
