Kitaev-Heisenberg model on the honeycomb lattice: A high-order treatment via the many-body coupled cluster method
Authors: Georgiou M. , Rousochatzakis I. , Farnell D. J. J. , Richter J. , Bishop R. F.
Published: August 2024

We study the spin-S Kitaev-Heisenberg model on the honeycomb lattice for S=1/2, 1, and 3/2, by using the coupled cluster method (CCM) of microscopic quantum many-body theory. This system is one of the earliest extensions of the Kitaev model and is believed to contain two extended spin liquid phases for any value of the spin quantum number S. We show that the CCM delivers accurate estimates for the phase boundaries of these spin liquid phases, as well as other transition points in the phase diagram. Moreover, we find evidence of two unexpected narrow phases for S=1/2, one sandwiched between the zigzag and ferromagnetic phases and the other between the Néel and the stripy phases. The results establish the CCM as a versatile numerical technique that can capture the strong quantum-mechanical fluctuations that are inherently present in generalized Kitaev models with competing bond-dependent anisotropies.

The complex consists of a potassium cation coordinated to the six oxygen atoms of a crown ether molecule and the two oxygen atoms of the oxalatotriphenylstannate anion. It crystallizes in the monoclinic crystal system within the space group P21. The tin atom is coordinated by one chelating oxalate ligand and three phenyl groups, forming a cis-trigonal–bipyramidal geometry around the tin atom. The cations and anions form ion pairs, linked through carbonyl coordination to the potassium atoms. The crystal structure features C—H...O hydrogen bonds between the oxygen atoms of the oxalate group and the hydrogen atoms of the phenyl groups, resulting in an infinite chain structure extending along a-axis direction. The primary inter-chain interactions are van der Waals forces.
Turbofan engine health status prediction with neural network pattern recognition and automated feature engineering
Authors: Szrama Sławomir
Published: August 2024

Purpose

This study aims to present the concept of aircraft turbofan engine health status prediction with artificial neural network (ANN) pattern recognition but augmented with automated features engineering (AFE).

Design/methodology/approach

The main concept of engine health status prediction was based on three case studies and a validation process. The first two were performed on the engine health status parameters, namely, performance margin and specific fuel consumption margin. The third one was generated and created for the engine performance and safety data, specifically created for the final test. The final validation of the neural network pattern recognition was the validation of the proposed neural network architecture in comparison to the machine learning classification algorithms. All studies were conducted for ANN, which was a two-layer feedforward network architecture with pattern recognition. All case studies and tests were performed for both simple pattern recognition network and network augmented with automated feature engineering (AFE).

Findings

The greatest achievement of this elaboration is the presentation of how on the basis of the real-life engine operational data, the entire process of engine status prediction might be conducted with the application of the neural network pattern recognition process augmented with AFE.

Practical implications

This research could be implemented into the engine maintenance strategy and planning. Engine health status prediction based on ANN augmented with AFE is an extremely strong tool in aircraft accident and incident prevention.

Originality/value

Although turbofan engine health status prediction with ANN is not a novel approach, what is absolutely worth emphasizing is the fact that contrary to other publications this research was based on genuine, real engine performance operational data as well as AFE methodology, which makes the entire research very reliable. This is also the reason the prediction results reflect the effect of the real engine wear and deterioration process.

Published: August 2024

Purpose

This study adopts the elaboration likelihood model and configuration perspectives to explore the internal mechanisms underlying the influence of live streaming on consumer trust building and purchase intention.

Design/methodology/approach

This study invited 757 experienced live streaming e-commerce users from Chinese platforms such as TikTok and RED, who participated in survey by filling questionnaires collected online. The research employed a mixed-method approach using SEM and fsQCA. SEM was utilized to analyze quantitative data to determine the direct and mediated relationships within product trust, while fsQCA served as a complement to identify the combinations of conditions that enhance product trust.

Findings

The findings reveal three important insights. Firstly, in the context of live streaming e-commerce, both product characteristics and streamer characteristics significantly influence consumers' trust in products. The para-social interaction plays a partial mediating role in the relationship between streamer characteristics and product trust. Secondly, four distinct paths are identified that contribute to enhancing product trust in live streaming e-commerce. Thirdly, PSI emerging as a core condition across all four paths, underscores the importance for merchants to foster positive social interactions with consumers beyond the live streaming environment.

Originality/value

This study enhances understanding of the dynamic live streaming e-commerce industry, offering insights into consumer behavior and practical guidance for merchants seeking to build engaged, trustworthy customer relationships.

Deciphering the links: evaluating central bank transparency impact on corruption perception index in G20 countries
Authors: Al Qudah Anas , Hailat Mahmoud Ali
Published: August 2024

Purpose

This study aims to explore the relationships between GDP growth, education spending, central bank transparency (CBT) and accountability on the corruption perception index within the G20 countries, emphasizing their combined effects and interdependencies.

Design/methodology/approach

Using the central bank transparency index (CBTI) introduced by Dinçer et al. (2019), an analysis spanning from 2002 to 2019 was conducted on selected G20 countries, further refining the results by excluding EU members. Data sources included World Bank statistics and CBTI data. The research deployed the heteroskedastic and contemporaneously correlated panel-corrected standard error model to detail the effects of the aforementioned factors on the corruption index.

Findings

The study revealed no statistical evidence that economic growth had an effect on reducing corruption. Education spending emerged as a potent tool in curbing corruption, especially in EU nations. A strong correlation was identified between CBT and reduced corruption, consistent across G20 countries, regardless of EU affiliation. The insights emphasize the importance of enhancing education spending and CBT in combating corruption. For effective anti-corruption measures, countries are encouraged to invest more in education, amplify internal checks and adopt transparent central bank policies. Further research could delve into cultural, historical and political variables to understand corruption dynamics comprehensively.

Originality/value

This study aspires to address the existing gaps in the literature and provide a substantial contribution to the ongoing discourse and efforts to understand and mitigate corruption within the G20 countries and globally.
Trends, risk factors and interventions for some mental health problems in the US children and adolescents: evidence from the National Survey of Children’s Health, 2016-2022
Authors: Lachaab Mohamed
Published: August 2024

Purpose

The purpose of this study is threefold: Determine recent trends in several mental health problems in the USA, identify risk factors that may be responsible for the trends and evaluate intervention policies to reduce the consequences of these problems.

Design/methodology/approach

This study used data from the National Survey of Children's Health (NSCH), a nationally representative survey of children under the age of 17 that was conducted between 2016 and 2022. Prevalence rates in the data take into account the probability of selection and nonresponse. Because of the possible correlation in the longitudinal responses in the data, an appropriate extension of the generalized linear models (the marginal models) was used. Marginal models, also known as population-average models, do not require distributional assumptions for the observations, only a regression model for the mean response. The avoidance of distributional assumptions leads to the use of the generalized estimating equations (GEE) method.

Findings

The author found that the odds of children and adolescents experiencing mental health problems in the USA changed over a seven-year period, from 2016 to 2022. Anxiety and depression, in particular, have both increased, with anxiety increasing faster than depression; however, behavioral issues and attention deficit disorder/attention deficit hyperactivity disoder (ADD/ADHD) remained stable until 2020 (the start of COVID-19), when they began to rise. This paper also found a link between increased social media use and increased mental health problems, and bullying has a negative impact on the mental health of children and adolescents.

Originality/value

The NSCH, an annual representative survey, was used in this study to assess mental health problems among children and adolescents in the USA. Marginal models, which enable the capture of potential correlations among observations of the same subject, were used in conjunction with the GEE method. This study differs from previous research, which used other surveys, pre-COVID-19 data points and logistic regressions that assumed independence in repeated observations.

Design/methodology/approach

A self-administered online survey was used to collect data from food delivery app users in the USA.

Findings

Findings validate a favorable role of perceived app security and menu description on trust in app recommendations. Trust was found to be positively related to involvement, commitment and willingness to provide feedback. The positive moderating role of perceived convenience and rewards and incentives was also confirmed in relation to consumers’ trust in app recommendations, and involvement and commitment

Originality/value

A key contribution of this study includes the development of a comprehensive model to understand postconsumption decisions related to the usage of food delivery apps. To the best of the authors’ knowledge, this study is also the first to unveil the antecedent and moderating factors related to food delivery app users’ willingness to provide feedback, share personal data and to pay more.

Authors: Zaheer Muhammad Asif , Anwar Tanveer Muhammad , Iantovics Laszlo Barna , Manzoor Maryam , Raza Muhammad Ali , Khan Zoia
Published: August 2024

Purpose

This research aimed to raise awareness about the need for safety measures and features of online food delivery applications (OFDAs) to build electronic trust (e-trust) with augmented purchase intention among customers. Moreover, this study explores the attributes of electronic commerce (e-commerce) and how e-trust influences the purchasing intention of consumers while ordering food through OFDAs including fear of contagious diseases. Determinants of e-commerce in the digital era profoundly impact the performance of enterprises.

Design/methodology/approach

Data from 493 food consumers collected from Federal Capital Territory (FCT) Pakistan, who were regular users of OFDAs. To scrutinize the dataset, confirmatory factor analysis (CFA) was conducted to assess the construct validity in this research study. Structural equation modeling (SEM), which is facilitated by Smart-PLS, was employed to examine the direct, moderation and mediation effects of the proposed model.

Findings

Results revealed the positive and significant impact of the e-trust on the purchase intention. Additionally, e-trust acted as a mediating factor in the connection between electronic security (e-security), electronic privacy (e-privacy), usability, electronic payment (e-payment), electronic innovativeness (e-innovativeness) and the buyer's purchase intention. Furthermore, the fear of contagious viruses negatively moderated the e-trust and purchase intention that weakened buying behavior.

Originality/value

This research is primarily centered on enhancing the comprehension regarding safety orientation within the context of an evolving restaurant industry. The findings of this study hold substantial contributions for academics, web developers, application designers, OFDAs, restaurants and other businesses since they indicate the attractiveness of OFDAs in generating feelings of pleasure and boosting users' intentions to keep using the application.
Improving the credibility of case study research in international business studies and beyond: a simple fix for a serious problem
Authors: Buck Trevor , Boussebaa Mehdi
Published: August 2024

Purpose

The field of international business (IB) formally welcomes and frequently calls for case study research, but the proportion of case study papers appearing in IB journals remains very small. This paper aims to support efforts to redress this imbalance by addressing an overlooked yet critical issue: the (mis)use of tenses when theorizing from case study findings. The authors reveal a pervasive use of the present tense and argue that this leads to decontextualization and, in turn, over-generalization. The paper also suggests ways in which this problem may be avoided in the future, thereby improving the credibility and status of case-based research and helping to de-marginalise it within IB.

Design/methodology/approach

A qualitative content analysis was applied to all (2,627) papers published between 2011 and 2021 in four leading IB journals. In total, 171 case study papers were identified over these 11 years, and a deeper content analysis was then performed to measure the extent of decontextualization/over-generalization implied by the inappropriate use of the present tense in the discussion and theorisation of research findings.

Findings

This study found that, out of 171 case study papers identified, 141 (82.5%) provided at least two instances of over-generalization as implied by the misuse of the present tense. However, some of these papers were found to feature statements that could be claimed to mitigate such inappropriate generalization. These mitigating factors included the repeated use of adverbial phrases denoting context and the use of a “propositional style” that clearly distinguished contextual findings from speculative, decontextualized generalizations. Nevertheless, 71 of the 171 (41.5%) papers still demonstrated inappropriate generalization, even after allowing for mitigating factors.

Originality/value

This study reveals a problematic writing practice and one which has arguably significantly contributed to the “decontextualization” problem critiqued in IB and management studies more broadly. The study also offers further insights into how decontextualization might be avoided, arguing that this problem would be significantly reduced if tenses were used appropriately in discussing and theorizing case study findings. Additionally, the study highlights the continued marginalization of qualitative research methods in IB and reinforces calls to address it.

Published: August 2024

Purpose

Additive manufacturing of polymer composites is a transformative technology that leverages the benefits of both composite material and 3D printing to produce highly customizable, lightweight and efficient composites for a wide range of applications.

Design/methodology/approach

In this research work, glass fiber-reinforced polylactic acid (PLA) filament is used to print the specimen via fusion deposition modeling process. The process parameters such as infill densities (40%, 50% and 60%) and raster angle/orientations (0°, 45° and 90°) are varied, and the specimens for tensile, flexural, impact, hardness and wear testing are prepared as per their respective ASTM standards.

Findings

The results revealed that with an increase in infill density, the mechanical properties of glass fiber-PLA specimens increase progressively. Optimal tensile properties and flexural properties are obtained at 0° and 90° raster angle orientations and 60% infill density. Minimum wear rate is achieved at 0° raster angle orientation and it increases at 45° and 90° raster angle orientations.

Originality/value

Using SEM, the microscopic analysis of the fractured specimen was analyzed to study the interface between the fibers and matrix and it indicates the presence of good adhesion between the layers at 60% infill density and 0° print orientation.
Improving fatigue behavior of selective laser melted 316 L stainless steel by ultrasonic-assisted burnishing
Authors: Sayadi Daniyal , Rangrizian Hossein , Khodabandeh Alireza , Khosrojerdi Mohammadreza , Khajehzadeh Mohsen , Razfar Mohammad Reza
Published: August 2024

Purpose

In this study, two postprocessing techniques, namely, conventional burnishing (CB) and ultrasonic-assisted burnishing (UAB), were applied to improve the fatigue behavior of 316 L stainless steel fabricated through selective laser melting (SLM). The effects of these processes on surface roughness, porosity, microhardness and fatigue performance were experimentally investigated. The purpose of this study is to evaluate the feasibility and effectiveness of ultrasonic-assisted burnishing as a preferred post-processing technique for enhancing the fatigue performance of additively manufactured components.

Design/methodology/approach

All samples were subjected to a sandblasting process. Next, the samples were divided into three distinct groups. The first group (as-Built) did not undergo any additional postprocessing, apart from sandblasting. The second group was treated with CB, while the third group was treated with ultrasonic-assisted burnishing. Finally, all samples were evaluated based on their surface roughness, porosity, microhardness and fatigue performance.

Findings

The results revealed that the initial mean surface roughness (Ra) of the as-built sample was 11.438 µm. However, after undergoing CB and UAB treatments, the surface roughness decreased to 1.629 and 0.278 µm, respectively. Notably, the UAB process proved more effective in eliminating near-surface pores and improving the microhardness of the samples compared to the CB process. Furthermore, the fatigue life of the as-built sample, initially at 66,000 cycles, experienced a slight improvement after CB treatment, reaching 347,000 cycles. However, the UAB process significantly enhanced the fatigue life of the samples, extending it to 620,000 cycles.

Originality/value

After reviewing the literature, it can be concluded that UAB will exceed the capabilities of CB in terms of enhancing the surface roughness and, subsequently, the fatigue performance of additive manufactured (AM) metals. However, the actual impact of the UAB process on the fatigue life of AM products has not yet been thoroughly researched. Therefore, in this study, this paper used the burnishing process to enhance the fatigue life of 316 L stainless steel produced through the SLM process.

Social GRRRAAACCCEEESSS in intercultural couple therapy: A semantic analysis
Authors: Kalaydjian Julia , Lugli Valentina , Singh Reenee
Published: August 2024

Social GGRRAAACCEEESSS must be addressed by the therapist, as they can easily and unintentionally be missed. The present article is based on a qualitative analysis of two case examples to draw out extracts of conversations around such biases. The purpose of the article is to bridge the heuristic of the Social GGRRAAACCEEESSS with the concept of semantic polarities and to illustrate the complex positioning of the therapist in encounters with intercultural couples. Both a semantic analysis and a deductive thematic analysis approach was used to analyse extracts of material from two case studies. The findings are discussed adopting joint systemic and psychodynamic approaches. Social GGRRAAACCEEESSS can either remain unvoiced and marginalised or can be brought to the surface. The article addresses the importance of the therapist's role in highlighting marginalised discourses and managing unintentional alliances.

Authors: Du An , Lu Zhaoqing , Hua Li
Published: August 2024

Food safety and authenticity analysis play a pivotal role in guaranteeing food quality, safeguarding public health, and upholding consumer trust. In recent years, significant social progress has presented fresh challenges in the realm of food analysis, underscoring the imperative requirement to devise innovative and expedient approaches for conducting on‐site assessments. Consequently, cellulose paper‐based devices (PADs) have come into the spotlight due to their characteristics of microchannels and inherent capillary action. This review summarizes the recent advances in cellulose PADs in various food products, comprising various fabrication strategies, detection methods such as mass spectrometry and multi‐mode detection, sampling and processing considerations, as well as applications in screening food safety factors and assessing food authenticity developed in the past 3 years. According to the above studies, cellulose PADs face challenges such as limited sample processing, inadequate multiplexing capabilities, and the requirement for workflow integration, while emerging innovations, comprising the use of simplified sample pretreatment techniques, the integration of advanced nanomaterials, and advanced instruments such as portable mass spectrometer and the innovation of multimodal detection methods, offer potential solutions and are highlighted as promising directions. This review underscores the significant potential of cellulose PADs in facilitating decentralized, cost‐effective, and simplified testing methodologies to maintain food safety standards. With the progression of interdisciplinary research, cellulose PADs are expected to become essential platforms for on‐site food safety and authentication analysis, thereby significantly enhancing global food safety for consumers.
A long cold storage protocol for Anisopteromalus calandrae based on promoting prepupal development and arresting early pupal growth under low temperature
Authors: Yang Jiapeng , Zhang Yue , Liu Li , Liu Die , Smagghe Guy , Yang Maofa , Chen Xiaoyulong , Yang Hong , Dai Renhuai
Published: August 2024

Anisopteromalus calandrae (Howard) shows great promise as an ectoparasitoid for controlling various coleopteran pests in warehouses. However, for a large‐scale release, it is crucial to establish an ample supply of A. calandrae while carefully maintaining their quality and effectiveness. Appropriate cold storage techniques are the key to achieving these goals. Previous studies on cold storage have focused on specific developmental stages and explored cold storage conditions that can be applied only to those stages. Herein, we examined the development, survival and reproductive capacity of A. calandrae at different temperatures (13, 16, and 19 °C) and storage durations (30, 60, and 90 d) and evaluated the fitness of the offspring. A. calandrae completed its egg‐to‐larva development and pupated at 16 °C, but its development was arrested at an early pupal stage. Even after 90 d of cold storage at 16 °C, the survival rate of A. calandrae remained high at 77%, with no significant impact on reproductive capacity. Furthermore, cold storage showed no negative effect on the F1 generation. In contrast, eggs stored at 13 °C failed to hatch, whereas those stored at 19 °C developed. Adults emerged after > 60 d. This indicates that storage at 19 °C is only suitable for short durations. Our findings highlight the developmental pattern of A. calandrae at 16 °C, indicating that the parasitic wasp can be stored for a long time at this temperature across all stages of development before pupation, substantially facilitating its mass reproduction and industrial production.
Association between estimated glucose disposal rate control level and stroke incidence in middle‐aged and elderly adults
Authors: Yao Jiangnan , Zhou Feng , Ruan Lingzhi , Liang Yiling , Zheng Qianrong , Shao Jiaxin , Cai Fuman , Zhou Jianghua , Zhou Hao
Published: August 2024

Background

To estimate glucose disposal rate (eGDR) as a newly validated surrogate marker of insulin resistance. Few studies have explored the association between changes in eGDR levels and stroke incidence. This study aims to explore the effect of the level of eGDR control on stroke and events.

Methods

Data were obtained from the China Longitudinal Study on Health and Retirement (CHARLS). The eGDR control level was classified using K‐means cluster analysis. Logistic regression analysis was used to explore the association between different eGDR control levels and incident stroke. Restrictive cubic spline regression was used to test the potential nonlinear association between cumulative eGDR and stroke incidence.

Results

Of the 4790 participants, 304 (6.3%) had a stroke within 3 years. The odds ratio (OR) was 2.34 (95% confidence interval [CI], 1.42–3.86) for the poorly controlled class 4 and 2.56 (95% CI, 1.53–4.30) for the worst controlled class 5 compared with class 1 with the best controlled eGDR. The OR for well‐controlled class 2 was 1.28 (95% CI, 0.79–2.05), and the OR for moderately controlled class 3 was 1.95 (95% CI, 1.14–3.32). In restrictive cubic spline regression analysis, eGDR changes are linearly correlated with stroke occurrence. Weighted quartile and regression analysis identified waist circumference and hypertension as key variables of eGDR for predicting incident stroke.

Conclusions

Poorly controlled eGDR level is associated with an increased risk of stroke in middle‐aged and elderly people. Monitoring changes in eGDR may help identify individuals at high risk of stroke early.

Management of diabetic ketoacidosis in children: Does early insulin glargine help improve outcomes?
Authors: Ohman‐Hanson Rebecca , Alonso G. Todd , Pyle Laura , McDonough Ryan , Clements Mark
Published: August 2024

Background

Rebound hyperglycemia following the resolution of diabetic ketoacidosis (DKA) is common in pediatric patients with type 1 diabetes, increasing the risk of recurrent DKA and complicating the transition to subcutaneous insulin. Multiple studies suggest that early administration of long‐acting insulin analogs during DKA management safely improves this transition.

Objective

This study aimed to determine whether early insulin glargine administration in children with DKA prevents rebound hyperglycemia and recurrent ketosis without increasing the rate of hypoglycemia or hypokalemia.

Methods

Patients aged <21 years presenting with DKA to Children's Mercy Kansas City between October 2012 and October 2016 were reviewed. They were categorized as Early (>4 h of overlap with intravenous [IV] insulin) and Late (<2 h of overlap) cohorts.

Results

We reviewed 546 DKA admissions (365 Early and 181 Late). Rebound hyperglycemia (>180 mg/dL) was lower in the Early group (66% vs. 85%, p ≤ 0.0001). Hypoglycemia (<70 mg/dL) during IV insulin administration was higher in the Early group than in the Late group (27% vs. 19%, p = 0.042). Hypoglycemia within 12 h of IV insulin discontinuation was lower in the Early group (16% vs. 26%, p = 0.012). Recurrent ketosis, hypokalemia, and cerebral edema were not different between the groups.

Conclusions

Early glargine administration in pediatric DKA management is safe, decreases the rate of rebound hyperglycemia, and improves the transition to subcutaneous insulin. Hypoglycemia is less frequent following IV insulin discontinuation with early glargine, but the IV insulin rate may need to be reduced to minimize hypoglycemia during IV insulin infusion.

Ichthyoses comprise a large heterogeneous group of skin disorders, characterized by generalized scaly and hyperkeratotic skin. We investigated a miniature poodle with early onset generalized scaling, dry and irregularly thickened skin, paw pad hyperkeratosis and abnormalities in hair and teeth. The clinical signs of ichthyosis were confirmed by histopathological examination, which revealed mild epidermal hyperplasia and lamellar orthokeratotic hyperkeratosis. A hereditary condition was suspected and a genetic investigation was initiated. We sequenced the whole genome of the affected dog and searched for potentially causative variants in functional candidate genes for the observed phenotype. The analysis revealed a heterozygous in‐frame deletion in DSP, NC_049256.1:g.8804542_8804544del resulting from a de novo mutation event as evidenced by genotyping leukocyte DNA from both parents. The 3 bp deletion is predicted to remove one aspartic acid without disrupting the open reading frame (XM_038584124.1:c.1821_1823del, XP_038440052.1:p.(Asp608del)). The DSP gene encodes desmoplakin, a desmosomal plaque protein, responsible for cell–cell adhesion to provide resistance to mechanical stress in epidermal and cardiac tissues. We hypothesize that the deletion of one amino acid in the N‐terminal globular head domain acts in a dominant negative manner and thus impairs the proper connection with other proteins. Several variants in DSP in humans and cattle have been described to result in different phenotypes associated with hair and skin abnormalities, sometimes in combination with variable cardiac and/or dental manifestations. In conclusion, we characterized a new syndromic ichthyosis phenotype in a dog and identified a de novo 3 bp deletion in the DSP gene as causal variant.

Introduction

We aimed to investigate the association between perinatal outcomes and placental pathological features in pregnant women with ACTD, including systemic lupus erythematosus (SLE), antiphospholipid antibody syndrome (APS), and undifferentiated connective tissue disease (UCTD).

Materials and Methods

Placental tissue from SLE (n = 44), APS (n = 45), and UCTD (n = 45) were included, and contemporaneous deliveries of placenta were served as a control group (n = 46) between September 2015 and March 2021. The placental histopathology was evaluated using the Manual of Human Placental Pathology and classified according to the Amsterdam consensus framework.

Results

SLE pregnant women have a higher rate of cesarean section (61.40%), premature birth (24.56%), and SGA (26.32%) when compared to control group (p = 0.008, p = 0.005, and p = 0.000, respectively). The rate of vascular malperfusion, inflammatory‐immune lesions, and other placental lesions in the SLE group was 47.73%, 56.82%, and 63.64%, which were higher than the control group (p = 0.000, p = 0.000, and p = 0.006, respectively). In the meantime, the incidence of inflammatory‐immune lesions in the APS group (42.22%, p = 0.004) and vascular malperfusion in the UCTD group (37.78%, p = 0.007) were increased when compared to the control group.

Conclusions

SLE appeared to confer increased risk for a wide range of adverse perinatal outcomes. We determined elevated placental histopathology risk for most women with ACTD, including vascular maldevelopment, vascular malperfusion, and inflammatory‐immune lesions.

Background

Ex vivo lung perfusion (EVLP) conducted outside of the transplant center has increased in recent years to mitigate its limitation by resources and expertise. We sought to evaluate EVLP performed at transplant centers and externally.

Methods

Lung transplant recipients were identified from the United Network for Organ Sharing Database. Recipients were then stratified into two groups based where they were perfused: Transplant Program (TP) or External Perfusion Centers (EPC). The groups were assessed with comparative statistics and long‐term survival was assessed by Kaplan–Meier method. The groups were then 1:1 propensity and this process was repeated.

Results

EPC use was generally restricted to the Southern United States. Following matching, there were no significant differences in post‐operative outcomes to include post‐operative stroke, dialysis, airway dehiscence, ECMO use, ventilator use or incidence of primary graft dysfunction Grade 3. Adjusted 3‐year survival was 68.9% (95% Confidence Interval [CI]: 60.9%–77.9%) for the TP group and 67.6% (95% CI: 61.0%–74.9%) for the EPC group (p = 0.69). In allografts with extended ischemia (14+ h), those in the TP group had significantly longer length of stay, prolonged ventilation and treated rejection in the 1st year, though no significant difference in mid‐term survival (p = 0.66).

Conclusion

EVLP performed at an EPC can be carried out with results and survival similar to allografts undergoing EVLP at a TP. EPCs will extend the valuable resource of EVLP to lung transplant programs without the resources to perform EVLP.

Culture matters: Cultural variability in corporate codes of conduct as a means to foster organizational legitimacy
Authors: Wolfgruber Daniel , Einwiller Sabine
Published: August 2024

In recent decades, implementing a code of conduct (CoC) as part of an organization's CSR infrastructure has become a sine qua non for gaining trust and fostering credibility. Despite numerous studies aimed at identifying cultural differences in the content of CoCs, little is known about what causes those differences and how they relate to an organization's communicative endeavor to gain trust and strengthen its legitimacy. In response, this article examines potential cultural differences in the public availability, design, and content of CoCs of corporations headquartered in countries in the Confucian Asian versus Anglo cultural clusters from the perspective of strategic communication. Drawing on the concepts of individualist versus collectivist culture and low‐ versus high‐context communication, the findings reveal significant differences, including that Anglo‐based companies more often make their CoCs publicly available and, in turn, significantly more comprehensive than Confucian Asian codes. Furthermore, compared with Anglo CoCs, significantly fewer CoCs of companies headquartered in Confucian Asia address the importance of moral values in daily business practices and sensitive issues such as prohibited behavior, whistleblowing, and sanctions following code violations. Those findings indicate significant institutional and cultural differences in companies' communication about ethical principles and corresponding conduct and suggest that, across cultures, CoCs differ in their content and are not accorded equal relevance as a means to foster legitimacy via CSR communication.
