Analyzing the intellectual structure of the Knowledge base on managing for sustainability, 1982–2019: A meta‐analysis
Authors: Hallinger Philip 
Published: May 2020

AbstractAlthough there have been numerous reviews of sustainability research in functional management disciplines, few reviews have examined this literature from a multidisciplinary perspective. This meta‐analysis integrated data and findings extracted from bibliometric reviews of research on managing for sustainability in seven different management disciplines: leadership, human resource management, entrepreneurship, innovation management, supply chain management, knowledge management, and strategic management. The meta‐analysis analyzed secondary bibliographic data associated with 9,476 Scopus‐indexed documents sourced in the seven reviews. The review found wide variability in the levels of scholarly engagement with sustainability issues across the seven disciplines. This finding was confirmed by the number of sustainability‐related documents identified in the different management disciplines, as well as by author productivity, citation and cocitation analyses. Among the seven fields of management research, scholars in supply chain management evidenced the strongest engagement with sustainability research. Using a similar combination of metrics, the review identified the most influential scholars in this the multidisciplinary management literature: Joseph Sarkis, Stefan Seuring, Stefan Schaltegger, Qingyun Zhu, Kannan Govindan, Michael Porter, and John Elkington. Author cocitation analysis of the intellectual structure of this literature found that the most influential “school of thought” was associated with “sustainable supply chain management”. Author cocitation analysis further identified core concepts that have emerged within and across these domains of sustainability management. The most influential multidisciplinary sustainability concepts, largely associated with strategic management, included resource‐based perspective, dynamic capabilities, competitive advantage, shared value, balanced scorecard, absorptive capacity, and triple bottom‐line.

AbstractThermal energy storage technology plays a crucial role in the thermal management system. Clay based organic phase change material has considerable advantages in the application of thermal energy storage due to low cost and high energy storage capacity. However, the low thermal conductivity of clay, especially poor interfacial thermal transfer, limits its thermal energy storage efficiency. Herein, stearic acid/reduced graphene oxide modified montmorillonite composites (SA/RGO‐MMT) were prepared by the vacuum impregnation of stearic acid into graphene modified montmorillonite matrix, which was obtained via the in situ reduction of graphene oxide on the surface of montmorillonite. Stearic acid is assembled in the porous structures of RGO‐MMT with the physical interactions. SA/RGO‐MMT possesses high melting enthalpy of 159 J/g, low extent of supercooling of 1.4 °C and excellent thermal reliability after 100 thermal cycling. Energy storage and release rates of SA/RGO‐MMT were significantly improved due to the enhanced interfacial thermal transfer by graphene. Therefore, SA/RGO‐MMT is a promising form‐stable phase change material for applications in solar heat storage fields. The strategy in this study highlights the importance of enhancing interfacial thermal transfer for the efficient thermal energy storage materials.

Abstract3D monolithic integrated photocatlysts were prepared by self‐assembly of graphene platelets decorated with manganese doped TiO2 nanoparticles. The self‐assembly was induced by chemical reduction at mild reaction conditions. The physico‐chemical properties of the photocatalysts were improved by addition of polymer nanoparticles within the 3D structures. The rGO presence in the nanostructures affected their light absorption capability, which was red shifted. As a result, the band gap dropped from 3.12 eV in Mn doped TiO2 to 2.8 eV in the monolithic composite made of rGO and TiO2. The photocatalysts were applied for the elimination of methylene blue (MB) from aqueous solutions, the degradation of which was monitored by the Matrix Assisted Laser Desorption Ionization Time of Flight Mass Spectrometry. It was shown that (i) MB was completely eliminated from aqueous solution; (ii) all the adsorbed MB was photocatalytically degraded under visible light, giving rise to various smaller molecules as intermediate products of degradation; and (iii) one part of the MB was completely mineralized, demonstrated by the presence of final degradation products. These results indicate that the presented materials seem to be a powerful tool in water purification process with double impact. On one hand, it will allow re‐use of water and decrease of its consumption in the textile producing plants, and on the other hand, it will assure protection of the environment by elimination of the hazards.
Structural Properties Change of Cassava Starch Granule Induced by High Shear Mixer

Published: May 2020

AbstractIn this work, a high shear mixer (HSM) is designed to produce a higher theoretical shear rate than conventional HSM in order to induce structure degradation of cassava starch granules. Using scanning electron microscopy and transmission electron microscopy, the processed cassava starch granule surface changes are identified without any major change in the granule shape. The carbohydrate component analysis and intrinsic viscosity suggest that the structural change is led by the removal of a relatively low‐molecular‐weight carbohydrate component from the granule. The changes in the crystalline and thermal properties are observed by the degradation process using a HSM. The process using a rotor speed of 15 000 rpm is found to significantly induce granule surface changes and carbohydrate removal. The decrease in granule crystallinity is correlated with an increase in the granule swelling power and solubility.
Fault diagnosis of the train communication network based on weighted support vector machine

Published: May 2020

AbstractMultifunction vehicle bus (MVB) is the most widely used train communication network which transmits controlling and supervising data. The faults of MVB will heavily affect the train's safe and stable operation. Due to the harsh operating environment and distributed structure, the MVB fault diagnosis has always been a difficult issue in the maintenance of the train. Many MVB faults will distort the physical waveforms and cause serious packet loss. Thus, we have extracted waveform features to characterize different MVB faults and turned the fault diagnosis into a pattern recognition problem. Then a classifier based on weighted support vector machine (WSVM) has been trained to diagnose and locate network faults. Considering that samples locating in different positions of the feature space have different influences on the support vector machine (SVM) hyperplane, we have proposed a multi‐hop edge approaching method to assign sample weights in WSVM. To identify the position of the tested sample, the hops from its location to the classification margin have been counted. The less the hop‐count, the closer to the classification margin and the larger the sample weight. Compared with SVM and other WSVM methods, the proposed method has better performance on the artificial synthetic datasets, the MVB dataset, and the benchmark datasets. © 2020 Institute of Electrical Engineers of Japan.

Published: May 2020

AbstractLinear adjustable efficient nanocontrollers that could respond to pH signals to trigger selective drug release were designed and discussed. They were fabricated by encapsulating theophylline into hydroxypropyl methylcellulose acetate succinate nanofibers through coaxial electrospinning. Theophylline was fixed in the core layer in an amorphous state. in vitro drug release behaviors were examined in simulated body fluid and tested by ultraviolet‐visible spectra. Expectedly, the nanocontrollers caused the drug to be autonomously released in weak alkaline solution rather than acid solution, with a sustained release over 12 hours. Thus, prior degrading or digesting in stomach can be avoided, and targeted drug releasing in the intestine can be realized. Moreover, the release rate was varied with regard to fiber diameter and drug content, indicating their adjustable property. The released performances were attributed to the synergistic effects of the chosen polymer and the core‐sheath structural advantages, for example, enteric solubility, drug encapsulation and large surface area. These results suggested that the designed nanocontrollers can serve as ideal candidates for a sustained targeted drug delivery system.

Published: May 2020

Abstract
Purpose
Controversy exists on the association of arterial hypertension (HTN) and neurovascular compression (NVC) at the ventrolateral medulla (VLM). No standardized and reproducible technique has been introduced yet for detection of NVC in HTN. This study aimed to generate, analyze and compare different results of exact reproducible anatomical 3D-representations of the VLM in patients with HTN, based on magnetic resonance imaging (MRI).

Methods
A 3T scanner provided MRI (T2-constructive interference in steady state (CISS) high resolution imaging and three-dimensional Time-of-flight (3D-TOF) angiography) from the posterior fossa of 44 patients with clinical treatment-resistant HTN. Image processing consists of segmentation of the CISS data, registration and fusion of the CISS and TOF data and visualization. For each patient two 3D-visualizations (before and after fusion) were obtained. The reproduction quality of the vessels, flow-related signal variability and pulsation artifacts were analyzed and compared, using a ranking score.

Results
Integrating vascular information from TOF into CISS data reduced artifacts in 3D-visualizations of exclusively processed CISS data. The quality of 3D-visualization of the vessels near the brain stem was significantly improved (p = 0.004). The results were reproducible and reliable. The quality of the 3D-presentations of neurovascular relationships at the VLM improved significantly (p < 0.001).

Conclusion
The 3D-visualization of fused image data provides an excellent overview of the relationship between cranial nerves and vessels at the VLM and simplifies the detection of NVC in HTN. It provides a powerful tool for future clinical and scientific research. Although microvascular decompression (MVD) in treatment resistant HTN is not a standard procedure, it can be discussed in selected patients with intractable severe HTN.

ZusammenfassungDie pulmonale Hypertonie (PH, Lungenhochdruck), und insbesondere die pulmonalarterielle Hypertonie (PAH), ist eine chronisch-progressive, fatale Erkrankung, für die aktuell – abgesehen von einer bilateralen Lungentransplantation – kein kurativer Therapieansatz besteht. Durch die jüngste Entwicklung und Verfügbarkeit von neuen „zielgerichteten“ PAH-Medikamenten („advanced“ oder „targeted therapies“), die mittlerweile für PAH im Erwachsenenalter zugelassen sind, haben sich allerdings die Lebenserwartung und -qualität von Erwachsenen und Kindern mit PAH erheblich verbessert.Wegen (1) des Mangels an für Kinder zugelassenen PAH-Medikamenten, (2) der gut begründeten Rationale für eine PAH-Pharmakokombinationstherapie im Kindesalter und (3) dem Fehlen schwerwiegender unerwünschter Wirkungen, sollten gerade jungen PH-Patienten die vorhandenen modernen pharmakologischen Therapiemöglichkeiten nicht vorenthalten bleiben. Ein solcher „Off-label“-Einsatz und dessen unbürokratische Erstattung (Finanzierung) durch die Kostenträger sind dringend erforderlich. Die Entscheidung zur spezifischen Therapie der pulmonalen Hypertonie mit Möglichkeit der Kombination von Medikamenten aller Substanzklassen – auch unter Einschluss von „Off-label-Präparaten“ – sollte durch einen Kinderkardiologen erfolgen, der ausreichend Erfahrung mit der Behandlung von Kindern mit pulmonaler Hypertonie – insbesondere mit vasoaktiven Medikamenten – hat, gefolgt von einer engmaschigen ambulanten Anbindung und Nachsorge dieser Patienten. Die mangelnde Zulassung moderner, gegen PAH gerichteter Arzneimittel oder die relativ dünne, evidenzbasierte Datenlage bei Kindern sollte die behandelnden Ärzte nicht davon abhalten, den jungen Patienten diese Therapien anbieten zu können.

Published: May 2020

AbstractThis paper proposes an approach to the planning and optimization of quality inspections within a multistage manufacturing process based on quality costs and the value added to the production process by inspections. Inspection errors and the resulting costs of repair and scrapping are taken into account. In addition, the capability of the manufacturing process and of the inspection system is included. A mathematical model for calculating quality costs was developed with a focus on its practical application.

Abstract
Purpose
We aimed to investigate associations between tau pathology and relative cerebral blood flow (rCBF), and their relationship with cognition in Alzheimer’s disease (AD), by using a single dynamic [18F]flortaucipir positron emission tomography (PET) scan.

Methods
Seventy-one subjects with AD (66 ± 8 years, mini-mental state examination (MMSE) 23 ± 4) underwent a dynamic 130-min [18F]flortaucipir PET scan. Cognitive assessment consisted of composite scores of four cognitive domains. For tau pathology and rCBF, receptor parametric mapping (cerebellar gray matter reference region) was used to create uncorrected and partial volume-corrected parametric images of non-displaceable binding potential (BPND) and R1, respectively. (Voxel-wise) linear regressions were used to investigate associations between BPND and/or R1 and cognition.

Results
Higher [18F]flortaucipir BPND was associated with lower R1 in the lateral temporal, parietal and occipital regions. Higher medial temporal BPND was associated with worse memory, and higher lateral temporal BPND with worse executive functioning and language. Higher parietal BPND was associated with worse executive functioning, language and attention, and higher occipital BPND with lower cognitive scores across all domains. Higher frontal BPND was associated with worse executive function and attention. For [18F]flortaucipir R1, lower values in the lateral temporal and parietal ROIs were associated with worse executive functioning, language and attention, and lower occipital R1 with lower language and attention scores. When [18F]flortaucipir BPND and R1 were modelled simultaneously, associations between lower R1 in the lateral temporal ROI and worse attention remained, as well as for lower parietal R1 and worse executive functioning and attention.

Conclusion
Tau pathology was associated with locally reduced rCBF. Tau pathology and low rCBF were both independently associated with worse cognitive performance. For tau pathology, these associations spanned widespread neocortex, while for rCBF, independent associations were restricted to lateral temporal and parietal regions and the executive functioning and attention domains. These findings indicate that each biomarker may independently contribute to cognitive impairment in AD.

AbstractBackgroundVarious techniques have been used for the execution of carotid endarterectomy; primary (PC), patch closure (CP) and eversion technique (ET).The superiority of any of them is still unproven. The aim of this study was to compare the long‐term outcomes of each technique in terms of cerebrovascular event (CVE), restenosis, survival and major cardiac event (MACE).MethodsBetween 2007 and 2018, a retrospective analysis of prospectively recorded data from three European tertiary centers was undertaken including 1.357 patients. Demographics, comorbidities and medical treatment were analyzed in relation to long‐term outcomes. Freedom from CVE, restenosis (> 70%), survival and MACE were estimated with Kaplan–Meier analysis curve.ResultsThe mean age was 69.5 ± 8 (72% males;79% asymptomatic). 472 (35%) were treated with PC, 504 (37%) with CP and 381 (28%) with ET. Differences among groups were observed in age (P < 0.001), gender (P < 0.01), hypertension (P = 0.01), dyslipidemia (P < 0.001) and statin treatment (P < 0.001). The mean follow‐up was 4.7 ± 3 years (median: 5 years). Seventy‐three patients presented a CVE during 8 years of follow‐up. The freedom from CVE including all techniques was 96% (SE 0.6%), 93% (SE 1%) and 89% (SE 1.6%), at 2, 5 and 8 years of follow‐up, respectively, with no difference between groups (P. 289). Freedom from restenosis was at 96% (SE 0.7%) and 89% (SE 5%) at 5 and 10 years, respectively, for all methods without differences. ET was associated with a higher mortality rate (P < 0.001) and MACE rate (P < 0.001).ConclusionsExcellent outcomes were achieved with all types of closure techniques with low rates of MACE and other adverse events during long‐term follow‐up after CEA.

Abstract
Background
The introduction of percutaneous mitral valve (MV) repair had an effect on clinical practice in comparison with surgical MV repair. Complete nationwide data are useful in examining how the introduction of a new technique influences clinical practice.

Methods
We analyzed procedural numbers, patient characteristics, and in-hospital outcomes for all percutaneous edge-to-edge and surgical MV reconstruction procedures performed in Germany between 2009 and 2015.

Results
12,664 percutaneous edge-to-edge and 22,825 surgical MV reconstructions were recorded. Numbers increased steadily, albeit more rapidly in the percutaneous edge-to-edge group (108–4079 vs. 2923–3603 with surgical MV reconstruction). Patients with percutaneous edge-to-edge MV reconstruction were older (75.6 ± 8.8 vs 61.6 ± 13.4 years, P < 0.001) and at higher operative risk (estimated logistic EuroSCORE 13.2% vs. 4.7%, P < 0.001) compared to those undergoing surgery. However, in-hospital mortality did not differ (2.9% vs. 2.8%; P = 0.395). This was also true for the subset of 2103 patients at intermediate operative risk as defined by a logistic EuroSCORE ≥ 4% and ≤ 9%. Of note, complication rates (except acute kidney injury) were more favorable in patients undergoing percutaneous edge-to-edge reconstruction.

Conclusions
Percutaneous edge-to-edge MV reconstruction has markedly changed clinical practice of MR therapy in Germany. Annual overall procedural numbers more than doubled, with a massive increase in percutaneous edge-to-edge procedures. Our data demonstrate its use mainly in high-risk patients and prove the favorable safety profile of this novel technique, with low in-hospital mortality and complication rates.
