Coherence in the use of a performance measurement system and compatibility between institutional logics in public hospitals
Authors: Leotta Antonio , Ruggeri Daniela 
Published: July 2022

Purpose
This study aims to explore how the use of a performance measurement system (PMS) reflects the compatibility between institutional logics at different levels. It emphasises the centrality of institutional logics behind actors’ expectations.

Design/methodology/approach
Drawing on pragmatic constructivism, the study assumes that a PMS is used coherently when it realises the values and beliefs of the actors involved. This requires that actors communicate and understand one another (communication coherence) and accept the PMS in use (value coherence). The study argues that a coherent use of a PMS reflects the compatibility between the institutional logics at the same (field levels) or different levels (field and societal levels). The empirical evidence comes from a large public hospital located in the south of Italy.

Findings
The empirical results describe episodes that highlight how the coherence in the use of PMS reflects the compatibility of institutional logics at different levels and episodes where the compatibility can be hindered by problems in the coherent use of the PMS related to value and communication coherence. A lack of communication and value coherence is highlighted in the use of PMS as “compromising accounts”.

Originality/value
The study sheds light on how coherence in the use of PMS reflects the compatibility between the institutional logics involved at different levels, suggesting that a focus on one prevailing logic must be avoided. The study extends logics compatibility beyond the field level to the societal level.

Authors: Verma Virendra Kumar , Kamble Sachin S. , Ganapathy L. , Tarei Pradeep Kumar 
Published: July 2022

Purpose
The purpose of this study is to identify, analyse and model the post-processing barriers of 3D-printed medical models (3DPMM) printed by fused deposition modelling to overcome these barriers for improved operational efficiency in the Indian context.

Design/methodology/approach
The methodology used interpretive structural modelling (ISM), cross-impact matrix multiplication applied to classification (MICMAC) analysis and decision-making trial and evaluation laboratory (DEMATEL) to understand the hierarchical and contextual relations among the barriers of the post-processing.

Findings
A total of 11 post-processing barriers were identified in this study using ISM, literature review and experts’ input. The MICMAC analysis identified support material removal, surface finishing, cleaning, inspection and issues with quality consistency as significant driving barriers for post-processing. MICMAC also identified linkage barriers as well as dependent barriers. The ISM digraph model was developed using a final reachability matrix, which would help practitioners specifically tackle post-processing barriers. Further, the DEMATEL method allows practitioners to emphasize the causal effects of post-processing barriers and guides them in overcoming these barriers.

Research limitations/implications
There may have been a few post-processing barriers that were overlooked by the Indian experts, which might have been important for other country’s perspective.

Practical implications
The presented ISM model and DEMATEL provide directions for operation managers in planning operational strategies for overcoming post-processing issues in the medical 3D-printing industry. Also, managers may formulate operational strategies based on the driving and dependence power of post-processing barriers as well as the causal effects relationships of the barriers.

Originality/value
This study contributes to identifying, analyzing and modelling the post-processing barriers of 3DPMM through a combined ISM and DEMATEL methodology, which has not yet been reviewed. This study also contributes to decision makers developing suitable strategies to overcome the post-processing barriers for improved operational efficiency.
Do Borrowers Intentionally Avoid Covenant Violations? A Reexamination of the Debt Covenant Hypothesis
Authors: BORDEMAN ADAM , DEMERJIAN PETER 
Published: July 2022

ABSTRACTIn this study, we replicate and extend the Dichev and Skinner [DS: 2002] study on the debt covenant hypothesis (DCH). We start by replicating DS and find results consistent with theirs. We then extend their work by changing three aspects of the research design: histogram bin width, calculation of slack, and statistical test of discontinuity. We find that the inference from DS is generally robust to varying these choices, although sensitive to different bin widths, during their sample period. We extend our analysis to the period 2000–2019 and find that support for DCH remains robust. We do, however, find a lack of support for DCH when examining the most common financial covenant, debt‐to‐EBITDA. These findings suggest a more nuanced perspective on DCH, whereby different types of financial covenants provide different incentives and abilities to avoid technical default.

AbstractIntroductionThe geriatric nutritional risk index (GNRI) is a widely used tool for nutritional assessment in patients receiving hemodialysis. The simplification of the GNRI calculation would be more useful for easier screening of malnutrition and for providing an intuitive stratification of mortality risk.MethodsWe retrospectively evaluated 218 Japanese patients receiving maintenance hemodialysis at two hemodialysis centers. The primary outcome was all‐cause mortality. The main exposure was a simplified GNRI (sGNRI) calculated as follows: sGNRI = serum albumin (g/dL) + 0.1 × body mass index (kg/m2).ResultsDuring the median 4.4‐year follow‐up, 56 patients died. Multivariable‐adjusted Cox proportional hazard risk models showed that patients with a lower sGNRI showed a significantly increased mortality risk. No significant difference was observed between the original GNRI and sGNRI regarding mortality predictability.ConclusionsGNRI is as useful as the original GNRI for screening for malnutrition and stratifying hemodialysis patients at increased mortality risk.

AbstractObjectiveIn recent years, the lung cancer incidence has grown and the population is younger. We intend to find out the true detection rate of pulmonary nodules and the incidence of lung cancer in the population and search for the risk factors.MethodHospital employees ≥40 years old who underwent low‐dose computed tomography (CT) lung cancer screening from January 2019 to March 2022 were selected to record CT‐imaging characteristics, pathology, staging, and questionnaires to investigate past history, smoking history, diet, mental health, etc. PM2.5 and radiation intake in radiation‐related occupation received monitoring in hospital.ResultThe detection rate of suspicious pulmonary nodules was 9.1% (233/2552), and the incidence rate of lung cancer (including adenocarcinoma in situ) was 4.0% (103/2552). Morbidity among doctors, nurses, technicians, administers, and logistics was no difference (p = 0.184), but higher in women than in men (4.7% vs 2.4% p = 0.002). The invasiveness increased with age and CT density of nodules (p = 0.018). The relationship between lung cancer morbidity and PM2.5 was not clear (p = 0.543); and no lung cancer has been found in employees related ionizing radiation.ConclusionThe high screening rate has brought about a high incidence of lung cancer. At present, the risk factor analysis of lung cancer based on small samples cannot find the direct cause. Most of the ground glass opacity (GGO)s detected by LDCT screening are indolent, but there are also rapidly progressive lung cancer. A predictive model to identify active and indolent GGO is necessary.

Published: July 2022

BackgroundProprotein convertase subtilisin/kexin type (PCSK9) inhibitor is a new drug class approved for treating dyslipidemias. Herein, we aimed to investigate the safety profiles of PCSK9 inhibitors (alirocumab and evolocumab) using the Food and Drug Administration Adverse Event Reporting System (FAERS).MethodsWe included adverse event (AE) reports regarding alirocumab and evolocumab submitted to the FAERs between 2015Q3 to 2021Q1. Disproportionality analyses, including reporting odds ratio (ROR), were performed to detect risk signals from the FAERs data to identify potential drug‐AE associations. A signal was considered when the lower limit of the 95% confidence interval of ROR exceeded 1 and ≥3 AEs were reported. The definition relied on system organ class and preferred terms established by the Medical Dictionary for Regulatory Activities.ResultsThe FAERS database documented 31 475 reports regarding PCSK9 inhibitors (alirocumab and evolocumab) from July 1, 2015, to March 31, 2021. Although some differences were detected, alirocumab and evolocumab shared considerably similar safety profiles. The most significant RORs and most common reports were injection‐site reactions (eg, injection‐site pain, bruising, haemorrhage, erythema), muscle‐related AEs (eg, myalgia, back pain, arthralgia, muscle spasms), influenza‐like illness, pain and headache.ConclusionData mining of the FAERs is useful for examining PCSK9 inhibitor‐induced AEs. Herein, our findings were largely consistent with clinical experience and could help clinicians improve the safety of PCSK9 inhibitors in clinical practice.
Grouped Generalized Estimating Equations for Longitudinal Data Analysis
Authors: Ito Tsubasa , Sugasawa Shonosuke 
Published: July 2022

Abstract
Generalized estimating equation (GEE) is widely adopted for regression modeling for longitudinal data, taking account of potential correlations within the same subjects. Although the standard GEE assumes common regression coefficients among all the subjects, such an assumption may not be realistic when there is potential heterogeneity in regression coefficients among subjects. In this paper, we develop a flexible and interpretable approach, called grouped GEE analysis, to modeling longitudinal data with allowing heterogeneity in regression coefficients. The proposed method assumes that the subjects are divided into a finite number of groups and subjects within the same group share the same regression coefficient. We provide a simple algorithm for grouping subjects and estimating the regression coefficients simultaneously, and show the asymptotic properties of the proposed estimator. The number of groups can be determined by the cross validation with averaging method. We demonstrate the proposed method through simulation studies and an application to a real data set.

AbstractObjectiveThis factorial randomized clinical trial (RCT) tested the effects of the surgical approach (flapped—FPS vs. flapless—FLS surgery) and loading protocol (delayed—DL vs. immediate—IL) for treatment with a four mini implant mandibular overdenture.Material and MethodsA total of 296 one‐piece titanium‐zirconium mini‐implants were inserted in 74 patients (IL/FLS = 17; IL/FPS = 18; DL/FLS = 20; and DL/FPS = 19). Outcomes included patient's perceived surgical burdens, clinical time, implant survival, and post‐surgical symptoms and complications, assessed immediately after surgery, in the 7‐day and 6‐week follow‐ups.ResultsPerceived surgical burdens were relatively low, higher for females, and no difference was found between FPS and FLS surgery. Surgical time was lower for FLS surgery. Overall symptoms were mild after 24 h, and higher for females. Less symptoms were recorded for the FLS surgery compared to the FPS for the delayed loading patients, and FLS surgery was associated with a lower risk of bleeding. No early implant failure was observed until the 6‐week follow‐up. Delayed was associated with discontinuous use of the prosthesis and poor function. Lower complaint rates were observed for immediate loading regardless of the surgery protocol.ConclusionsMini implants for mandibular overdenture are a feasible option regardless of surgical access and loading protocol, with high safety and predictable survival rates, and low incidence of post‐insertion complications. FLS surgery requires less clinical time and results in easier intraoral prosthetic incorporation of attachments compared to FPS surgeries. Immediate loading did not increase the risk of early implant failure when satisfactory primary stability was achieved.
Exploring Patterns of Stability and Change in Caregivers' Word Usage Across Early Childhood

Published: July 2022

AbstractThe linguistic input children receive across early childhood plays a crucial role in shaping their knowledge about the world. To study this input, researchers have begun applying distributional semantic models to large corpora of child‐directed speech, extracting various patterns of word use/co‐occurrence. Previous work using these models has not measured how these patterns may change throughout development, however. In this work, we leverage natural language processing methods—originally developed to study historical language change—to compare caregivers' use of words when talking to younger versus older children. Some words' usage changed more than others; this variability could be predicted based on the word's properties at both the individual and category levels. These findings suggest that caregivers' changing patterns of word use may play a role in scaffolding children's acquisition of conceptual structure in early development.

Published: July 2022

AbstractIntroductionThe presence of median arcuate ligament (MAL) during orthotopic liver transplantation (OLT) may cause a significant reduction in the arterial hepatic flow. The aim of the present study is to investigate the impact of MAL on biliary complications in patients who underwent OLT.MethodsWe performed a retrospective case‐control study among patients who underwent OLT in Geneva University Hospital between 2007 and 2017, depending on the presence or absence of MAL. The matching was performed according to age, gender, lab‐MELD score at the time of OLT and type of donor (living or dead). The presence of MAL was assessed by an expert liver radiologist on the preoperative CT angiographic evaluation.ResultsThe incidence of MAL was 6.1% (19 patients). Baseline characteristics were comparable between the two groups. No significant difference in biliary complications was found between patients with and without MAL (37% and 24%, respectively). No patient presented hepatic artery thrombosis. After logistic regression, in patients with MAL, the MAL release and gastroduodenal artery preservation compared to no treatment, showed an odds ratio for post‐OLT biliary complications of 1.5 and 1.25, respectively. There was no difference in overall graft survival and in hazard for biliary complications between patients with and without MAL.ConclusionIn the present study, we did not find any difference in the prevalence of biliary and arterial complications between patients with and without MAL. The choice of MAL treatment did not influence in a significant way the overall outcome and development of complications. However, if, at the end of arterial reconstruction, the arterial flow is not adequately established, MAL needs to be treated with the least invasive technique.
Children over‐imitate adults and peers more than puppets

Published: July 2022

AbstractResearchers commonly use puppets in development science. Amongst other things, puppets are employed to reduce social hierarchies between child participants and adult experimenters akin to peer interactions. However, it remains controversial whether children treat puppets like real‐world social partners in these settings. This study investigated children's imitation of causally irrelevant actions (i.e., over‐imitation) performed by puppet, adult, or child models. Seventy‐two German children (AgeRange = 4.6–6.5 years; 36 girls) from urban, socioeconomically diverse backgrounds observed a model retrieving stickers from reward containers. The model performed causally irrelevant actions either in contact with the reward container or not. Children were more likely to over‐imitate adults’ and peers’ actions as compared to puppets’ actions. Across models, they copied contact actions more than no‐contact actions. While children imitate causally irrelevant actions from puppet models to some extent, their social learning from puppets does not necessarily match their social learning from real‐world social agents, such as children or adults.Research Highlights
We examined children's over‐imitation from adult, child, and puppet models to validate puppetry as an approach to simulate non‐hierarchical interactions.
Children imitated adults and child models at slightly higher rates than puppets.
This effect was present regardless of whether the irrelevant actions involved physical contact to the reward container or not.
In our study children's social learning from puppets does not match their social learning from human models.
Insight into Hofmeister effects on aggregation of 2:1 and 1:1 type clay minerals

Published: July 2022

Abstract2:1 and 1:1 types of clay minerals are ubiquitous in soil, and their different surface properties result in distinct environmental behaviours. In this study, dynamic light scattering (DLS) technology was adopted to determine the aggregation kinetics of 2:1 type (Montmorillonite [Mt]) and 1:1 type (Kaolinite [Ka]) clay minerals in different electrolytes. Hofmeister effects on their aggregation characteristics and mechanisms were explored. The results showed that the activation energy and critical coagulation concentration (CCC) for Mt and Ka aggregation followed Hofmeister sequences of Na+ > K+ > Cs+, Mg2+ > Ca2+ > Zn2+ ≈ Cd2+ > Cu2+> Pb2+. The analyses of physical insights into those differences revealed that the observed Hofmeister sequence was produced from the different non‐classical polarisation of cations and surface O atoms in the strong electric field of clay, which led to non‐electrostatic force adsorption of cations at the surface (or in the Stern layer). In this study, the effective charge coefficient γ was employed to characterise the intensity of the non‐electrostatic adsorption forces of cations arising from the non‐classical polarisation, and the γ values followed Na+ < K+ < Cs+, Mg2+ < Ca2+ < Zn2+ = Cd2+ < Cu2+ < Pb2+. For alkali and alkali earth metal cations with same valence, the more the electron layers, the ‘softer’ the electron cloud, the stronger the non‐classical polarisation effects in the electric field and the stronger ability to shield the electric field around the particle, which finally lead to the larger γ and lower CCC for clay minerals aggregation. For heavy metal cations, different s/p/d empty orbitals provided the basis for the difference in polarisation‐induced coordination between heavy metal cations with surface O atoms on clay. The results also showed that, the Hofmeister effects on Mt/Ka aggregation were different, it was from the differences in Hamaker constant and surface charge density for the two clay minerals.Highlights
Mt and Ka aggregations exhibited different Hofmeister effects.
Repulsive force among Mt particles was much larger than Ka.
Cationic polarisation played critical role in particle interactions of Mt.
Polarisation‐induced covalent adsorption of cations was observed at Mt surface.
Temperature effect on the static mode I delamination behavior of aerospace‐grade composite laminates: Experimental and numerical study

Published: July 2022

AbstractAerospace structures are exposed to high‐temperature conditions during service. In‐depth study for the temperature effect on composite interlaminar properties is important for the structural design and reliable application. In this study, mode I delamination behaviors at different temperatures are investigated, to understand the effects of temperature on the delamination growth process, including fracture toughness, bridging stress, and failure mechanism. It is found that R‐curve behavior presents at all temperatures. The initial and steady‐state fracture toughnesses exhibit linear increase trends with the increase of the temperature, from which equations are established to predict the initial and steady‐state fracture toughnesses at other temperatures. More bridging fibers are observed at higher temperatures, and the resulted fracture resistance at 130°C is 136.9% higher than that at room temperature. The maximum bridging stress also increases with the increase of temperature. A numerical framework based on the cohesive zone model is established for delamination modeling. Material parameters at various temperatures are obtained by an exponential model. Suitable values of interfacial parameters in cohesive elements are numerically determined. Predicted load–displacement responses agree well with the experimental ones, illustrating the applicability of the proposed numerical method.
