Conception and Interpretation of Interdisciplinarity in Research Practice: Findings from Group Discussions in the Emerging Field of Digital Transformation
Authors: Schmitt Josephine B. , Goldmann Anne , Simon Samuel T. , Bieber Christoph 
Published: February 2023

AbstractIn recent years, we have been observing the phenomenon of an emerging scientific field: digital transformation research (DTR). Due to the diversity and complexity of its object of research digital, transformation is not effectively researchable if confined to the boundaries of individual disciplines. In the light of Scientific/Intellectual Movement theory (Frickel and Gross 2005), we wonder how interdisciplinarity could and should be mobilized to further advance the development of the field of DTR. To answer this question, we (a) need to understand how interdisciplinarity is conceived and (b) how it is considered in research practice by researchers in the emerging field. This is important, as scientists’ application of interdisciplinarity will highly influence an emerging field, shape its growth, consolidation as well as its academic establishment. We conducted six group discussions with 26 researchers from different disciplines and career levels (PhD students, postdocs, professors). The discussions were studied with a structuring qualitative content analysis. The results reflect the vagueness of the concept of interdisciplinarity. Interdisciplinarity is largely conceived as multidisciplinarity. Further, the interviewees mentioned more challenges than opportunities when it comes to interdisciplinary DTR. The present study widens the scientific understanding about how researchers of different career levels perceive, learn, and practice interdisciplinarity in DTR. It further provides valuable indications of how interdisciplinary research in an emerging field can be profitably shaped for practice.

Abstract
Purpose
To comprehensively investigate prognostic factors, including clinical and molecular factors and treatment modalities, in adult glioma patients with leptomeningeal metastases (LM).

Methods
Total 226 patients with LM (from 2001 to 2021 among 1495 grade 2 to 4 glioma patients, 88.5% of LM patients being IDH-wildtype) with complete information on IDH mutation, 1p/19q codeletion, and MGMT promoter methylation status were enrolled. Predictors of overall survival (OS) of entire patients were determined by time-dependent Cox analysis, including clinical, molecular, and treatment data. Subgroup analyses were performed for patients with LM at initial diagnosis and LM diagnosed at recurrence (herein, initial and recurrent LM). Identical analyses were performed in IDH-wildtype glioblastoma patients.

Results
Median OS was 17.0 (IQR 9.7–67.1) months, with shorter median OS in initial LM than recurrent LM patients (12.2 vs 20.6 months, P < 0.001). In entire patients, chemotherapy and antiangiogenic therapy were predictors of longer OS, while male sex and initial LM were predictors of shorter OS. In initial LM, higher KPS, chemotherapy, and antiangiogenic therapy were predictors of longer OS, while male sex was a predictor of shorter OS. In recurrent LM, chemotherapy and longer interval between initial glioma and LM diagnoses were predictors of longer OS, while male sex was a predictor of shorter OS. A similar trend was observed in IDH-wildtype glioblastoma.

Conclusion
Active chemotherapy and antiangiogenic therapy demonstrated survival benefit in glioma patients with LM. There is consistent female survival advantage, whereas longer interval between initial glioma diagnosis and LM development suggests longer OS in recurrent LM.
Does temporary employment increase length of commuting? Longitudinal evidence from Australia and Germany
Authors: Laß Inga , Skora Thomas , Rüger Heiko , Wooden Mark , Bujard Martin 
Published: February 2023

AbstractOn average, temporary jobs are far less stable than permanent jobs. This higher instability could potentially lower workers’ incentives to relocate towards the workplace, thereby resulting in longer commutes. However, surprisingly few studies have investigated the link between temporary employment and commuting length. Building on the notion that individuals strive to optimize their utility when deciding where to work and live, we develop and test a theoretical framework that predicts commuting outcomes for different types of temporary workers – fixed-term, casual and temporary agency workers – and in different institutional contexts. We estimate fixed-effects regression models using 17 waves of data from the Household, Income and Labour Dynamics in Australia (HILDA) Survey and the German Socio-Economic Panel (SOEP). As expected, the results show that the link between temporary employment and commuting length varies by employment type and institutional context. Agency work is associated with longer commutes than permanent work in both countries, whereas this applies to fixed-term contracts for Germany only. For casual work, the findings suggest no commuting length differential to permanent employment. In terms of policy, our findings suggest lengthy commuting can be a side effect of flexible labour markets, with potentially negative implications for worker well-being, transportation management and the environment.
Impact of the Amount of the Gold Layer on the Tribological Performance of the Ceramic Conversion Treated CP-Titanium
Authors: Zhang Zhenxue , Yu Hao , Li Xiaoying , Dong Hanshan 
Published: February 2023

Abstract
Titanium alloys are characterised by poor tribological properties, and a ceramic TiO2 layer formed on the surface can greatly improve its performance. By pre-depositing a gold layer on the titanium surface, the gold particles promoted the outward diffusion of titanium in the ceramic conversion treatment to react with the inward-coming oxygen to form a compact titanium dioxide layer. The surface morphology, microstructure, and phase constituents were characterised by SEM/EDX and XRD. The adhesion of the oxide layers was assessed by a scratch test. The distribution of gold particles in the oxide layer enhanced the surface hardness and reduced the friction and wear against a WC (tungsten carbide) ball in the reciprocal tribological test. The ceramic conversion process was accelerated efficiently at 620–660 °C, and the more gold pre-deposited, the thicker the oxide layer.

Published: February 2023

Abstract

Introduction
Obesity is associated with disturbed gut microbiota homeostasis that translates into altered intestinal and blood metabolite profiles. The long-chain fatty acid (LCFA) may be absorbed in the intestine, but until now, their composition in intestinal contents of patients with obesity has not been studied. The aim of the present study was to verify whether obesity is related to any changes in fecal LCFA content and whether intestinal LCFA content may be associated with the health status of patients with obesity.

Methods
The fatty acid composition has been studied in stool samples obtained from 26 patients with morbid obesity and 25 lean subjects by gas chromatography–mass spectrometry. The dietary habits were assessed using the Food Frequency Questionnaire (FFQ-6).

Results
Our results show for the first time that lean subjects and patients with obesity differ in their stool LCFA profiles. The levels of most n-3 polyunsaturated fatty acids (PUFAs) and n-6 PUFAs were significantly higher in fecal samples from people with obesity than in those from lean controls.

Conclusions
Based on the current knowledge, we have defined three hypotheses that may explain proving the cause-and-effect relationships observed differences in fecal LCFA profiles between patients with obesity and lean subjects. They may be related to alterations in fat digestion and/or LCFA absorption and diet. However, proving the cause-and-effect relationships requires further research.

Non-linear INAR(1) processes under an alternative geometric thinning operator
Authors: Barreto-Souza Wagner , Ndreca Sokol , Silva Rodrigo B. , Silva Roger W. C. 
Published: February 2023

AbstractWe propose a novel class of first-order integer-valued AutoRegressive (INAR(1)) models based on a new operator, the so-called geometric thinning operator, which induces a certain non-linearity to the models. We show that this non-linearity can produce better results in terms of prediction when compared to the linear case commonly considered in the literature. The new models are named non-linear INAR(1) (in short NonLINAR(1)) processes. We explore both stationary and non-stationary versions of the NonLINAR processes. Inference on the model parameters is addressed and the finite-sample behavior of the estimators investigated through Monte Carlo simulations. Two real data sets are analyzed to illustrate the stationary and non-stationary cases and the gain of the non-linearity induced for our method over the existing linear methods. A generalization of the geometric thinning operator and an associated NonLINAR process are also proposed and motivated for dealing with zero-inflated or zero-deflated count time series data.
Toward an understanding of occupational burnout among employees with autism – the Job Demands-Resources theory perspective
Authors: Tomczak Michał T. , Kulikowski Konrad 
Published: February 2023

AbstractThis article aims to gain insight into the phenomenon of occupational burnout among employees with autism based on the theoretical framework of the Job Demands-Resources theory and the literature on employees with autism in the workplace. Firstly, we argue that although the resources and demands of the neurotypical and neurodivergent employees might be different, the theoretical mechanism of occupational burnout formation remains similar among the neurotypical and neurodivergent employees, leading to the similar burnout experience. Next, we distinguish key demands that might drain neurodiverse employees’ energy, and spark burnout, and propose a set of resources that might foster their achievement of work goals and mitigate demanding working conditions. We emphasise that the nature of job demands/resources that may cause burnout is not universal but might depend on how employees evaluate them, thus neurotypical and neurodiverse workers who evaluate the same work characteristics differently might complement each other, increasing organisational diversity without losing productivity. Our conceptual elaboration contributes to the theory and practice of healthier workplaces by providing tools and inspiration to managers, policymakers, and all stakeholders interested in creating a diverse and productive workplace. Moreover, our work might spark a much needed debate on occupational burnout among employees with autism and encourage conducting further empirical studies.

Published: February 2023

AbstractImmune thrombocytopenic purpura (ITP) is an autoimmune disease with possible dysregulation of the apoptotic pathways. We aimed to evaluate the possible role of some apoptotic markers (caspase 3, caspase 8 and BCL2) in the pathogenesis and course of ITP. We investigated some apoptotic markers (caspase 3, caspase 8 and BCL2) using the flow cytometry in 60 children with newly diagnosed ITP, 20 children with chemotherapy-related thrombocytopenia (CRT) and 20 healthy children. We also assessed the effects of intravenous immunoglobulin (IVIG) and methyl prednisolone therapies on the platelet apoptosis in children with newly diagnosed ITP. We demonstrated significantly higher values of caspase 3 in the newly diagnosed ITP group than control and CRT groups, and non-significantly higher values of caspase 8 in the ITP group than the healthy group. After IVIG treatment, the platelet count increased in all patients, and there was a significant decrease in caspase 3 and caspase 8 levels while BCL2 level increased. Regarding methylprednisolone treatment, there was a significant decrease in BCL2 and caspase 8 levels while caspase 3 levels did not significantly decrease. There is a possible role of the caspase dependent cell death pathway of the platelets in the occurrence of newly diagnosed ITP. There is heterogeneity in the apoptotic changes of newly diagnosed ITP children who received IVIG versus those who received methylprednisolone.
Multiple criteria decision making and robust optimization to design a development plan for small and medium-sized enterprises in the east of Iran

Published: February 2023

AbstractThis paper is based on a project of developing small and medium-sized enterprises in South Khorasan, Iran. A combination of multiple criteria decision making and robust multi-objective optimization is used for prioritizing industrial clusters and optimally assigning governmental funds. First, criteria for evaluating clusters are weighted using the best-worst method and clusters are prioritized using the VIKOR method. Second, governmental funding is assigned to the highest priority cluster using robust multi-objective mathematical programming. An innovative method is applied to identify the solution of the Pareto-front with the highest efficiency. In a case study from South Khorasan, computational results show that international market share attraction is the most important criterion and the age of the cluster is the least important criterion in the development of the industrial clusters. The cluster defined for barberry and jujube fruits is determined to be the first-ranked cluster. Most of the total available budget for the development of this cluster is assigned to action plans for marketing and trade development and for investment and financial planning. The proposed methodology thus successfully aided the decision makers to plan their work regarding funding of industrial clusters. We believe that the methodology can be applied as a general tool to help managers of industrial development to better assign governmental funding to develop industrial clusters.

Published: February 2023

Abstract
Opposed to piloted ignition, where a substance is ignited by an external flame or spark, the term auto-ignition describes the onset of combustion by spontaneous ignition without an external source. In this study, the influence of the size of spherical wood samples and the temperature surrounding the samples was investigated by performing ignition experiments in a muffle furnace with beech and spruce wood. On a specially constructed rig, spheres with four different diameters (8 mm, 12 mm, 18 mm, and 25 mm) were put into a preheated furnace at five isothermal temperatures (240 °C, 270 °C, 300 °C, 330 °C, and 360 °C). For every temperature, diameter, and wood species, the experiments were repeated eight times, and positions of the spheres on the rig were changed for every measurement. Temperatures inside the samples were recorded with thermocouples (TC) positioned in holes drilled to the middle of the spheres. With rising size and temperature, samples were more prone to auto-ignition in a glowing mode, due to a larger, highly reactive pyrolyzed surface and internal overheating. During heating and oxidative pyrolysis, isothermal phases were present at approximately 360 °C in the recorded temperature curves. The comparison to simultaneous thermal analysis (STA) measurements shows decomposition of hemicelluloses, and cellulose is highest around 360 °C. It is concluded that pyrolysis and disintegration of the main wood constituents use up all arising energy. Due to differences in the composition of the wood polymers, beech wood samples already ignite at lower temperatures compared to spruce wood samples with the same diameter. It can be concluded that the size is a critical factor for auto-ignition at the used temperatures. Larger samples will produce more volatile compounds during pyrolysis and have a larger pyrolyzed, porous surface area where heterogenous oxidation reactions can happen. The influence of the size is already critical at differences on the millimetre scale.

Published: February 2023

AbstractThe main objective of our ongoing research is data collection for integrity management (IM) tasks, in other words for pipeline integrity management system (PIMS), helping the transporting pipeline operators in different decision situations. Either the reserves of the girth welds after a long-term operation can be identified or the girth welds with different defects should be repaired and/or replaced. From the operators’ point of view, the long-term operation is the cost-effective way; however, from the safety point of view, the managing of the lifecycle of the pipeline is the more reliable way. Unfortunately, inadequate girth welds cause catastrophic damages in transporting pipelines, all over the world. Consequently, the optimal operation of the pipelines is a complex task. The paper introduces our investigation program executed on full-scale pipeline sections. Fatigue (100,000 cycles) and burst tests were executed on different pipeline sections containing girth welds. Long-term operated and replaced gas transporting pipeline sections, furthermore, both appropriate and inadequate girth welds were investigated. The testing results and the damage histories were compared with each other; safety factor (SF) was defined and calculated for the assessment of the reliability of the girth welds.
Multi-criteria decision-making of manufacturing resources allocation for complex product system based on intuitionistic fuzzy information entropy and TOPSIS

Published: February 2023

AbstractManufacturing resources allocation (MRA) is important area, and a significant challenge is encountered when considering high value, customized, complex structure and long lifespan of complex product system (CoPS). The relationship between uncertainty factors (i.e., inputs and outputs) of processes in CoPS’s manufacturing, operation and maintenance needs comprehensive trade-offs in the preliminary MRA stage. Meanwhile, the CoPS’s MRA schemes are contradictory from a customer’s perspective with different emphasis on operating cost related to operation and maintenance stage. These problems are unavailable in traditional expressions for model and objective function. In this paper, a new variant of MRA multi-criteria decision-making (MCDM) model of CoPS (MRA&CoPS) is developed to evaluate MRA schemes with considering CoPS’s lifecycle. Meanwhile, considering characteristics of CoPS and customer-involved MRA process, the three-layer criteria cumulative model is established. In the proposed method, intuitionistic fuzzy sets (IFSs) based subjective–objective hybrid fuzzy method is presented to deal with uncertainty of evaluation criteria. The weights of criteria are determined by the proposed intuitionistic fuzzy information entropy (IFIE). The hybrid IFIE-TOPSIS method is proposed to obtain the optimum MRA scheme by ranking results. An example of CoPS’s MRA in a case enterprise is addressed to verify the rationality and validity of the proposed method. The results show that the proposed method is more preferable and robust in MCDM problem of MRA&CoPS.
Relational Aggression in Adolescents Across Different Cultural Contexts: A Systematic Review of the Literature

Published: February 2023

AbstractRelational aggression is defined as harming peers’ relationships through exclusion, rumors, and manipulation. Seminal work on adolescent relational aggression has documented its prevalence across diverse cultural settings. However, efforts to investigate the impact of cultural norms on relational aggression are limited. The purpose of the present review is to present the existing research on relational aggression across cultures during adolescence, a developmental period where the importance of peer relations peaks. Emphasis was placed on gender differences in relational aggression cross-culturally. A systematic literature search between 2010 and 2022 yielded 76 published studies, classified according to studies’ characteristics (participants, information source, study’s design), gender differences and relational aggression’s prevalence. Adolescents in European and American countries reported low scores on relational aggression, while the majority of the studies that were conducted in Asia indicated higher engagement in relational aggression. In Africa and Australia, the findings were inconclusive regarding the prevalence of relational aggression. One third of the studies found non-significant gender differences in adolescent relational aggression. The majority of the studies in Africa, Asia, Australia, and Europe showed that males scored higher on relational aggression, while in America most of the research demonstrated higher scores for females. Future comparative research on relational aggression during adolescence across cultures is suggested.
Empirical likelihood inference for monotone index model

Published: February 2023

AbstractThis paper proposes an empirical likelihood inference method for monotone index models. We construct the empirical likelihood function based on a modified score function developed by Balabdaoui et al. (Scand J Stat 46:517–544, 2019), where the monotone link function is estimated by isotonic regression. It is shown that the empirical likelihood ratio statistic converges to a weighted chi-squared distribution. We suggest inference procedures based on an adjusted empirical likelihood statistic that is asymptotically pivotal, and a bootstrap calibration with recentering. A simulation study illustrates usefulness of the proposed inference methods.
