Identifying physiological correlates of cybersickness using heartbeat-evoked potential analysis
Authors: Chang Eunhee , Kim Hyun Taek , Yoo Byounghyun 
Published: January 2022

AbstractMany studies have consistently proven that repeatedly watching virtual reality (VR) content can reduce cybersickness. Moreover, the discomfort level decreases when the VR content includes an unusual orientation, such as an inverted scene. However, few studies have investigated the physiological changes during these experiences. The present study aimed to identify psychophysiological correlates, especially the neural processing, of cybersickness. Twenty participants experienced two types of VR orientation (upright and inverted), which were repeated three times. During the experience, we recorded the participants’ subjective levels of discomfort, brain waves, cardiac signals, and eye trajectories. We performed a heartbeat-evoked potential (HEP) analysis to elucidate the cortical activity of heartbeats while experiencing cybersickness. The results showed that the severity of cybersickness decreased as the participants repeatedly watched the VR content. The participants also reported less nausea when watching the inverted orientation. We only found a significant suppression at the fronto-central HEP amplitudes in the upright orientation for the physiological changes. This study provides a comprehensive understanding of bodily responses to varying degrees of cybersickness. In addition, the HEP results suggest that this approach might reflect the neural correlates of transient changes in heartbeats caused by cybersickness.

Abstract
Background
Migraine affects more than a billion people all over the world and requires critical employment of healthcare resources. Telemedicine could be a reasonable tool to manage people suffering from headaches, and it received a big push from the COVID-19 pandemic.

Objective
This review aims to propose a practical approach for the virtual management of these patients.

Methods
To do this, we conducted a literature search, including 32 articles relevant to the topic treated in this review.

Results
The most challenging step in telemedicine applied to practical neurology remains the clinical assessment, but through a careful headache history and a recently proposed entirely virtual neurological assessment, this hitch can be easily overcome. Electronic diary compilations and virtual administration of disability-measuring scales, conversely, are the key features of effective long-term follow-up although we do not have apps that met the criteria of scientific reliability. Furthermore, tele-rehabilitation seems to be effective and has demonstrated to be a solution to alternatively treat chronic patients at home, and can be considered part of the remote management of headache patients. Moreover, virtual management of headaches finds an application in specific communities of patients, as pediatric patients and for rural communities of low- and middle-income countries suffer from health disparities, with inadequate resources and knowledge gaps.

Conclusion
Telemedicine could be promising for patients with no regular or convenient access to headache specialists and seems to be a priority in managing migraine patients to avoid non-urgent hospitalizations
Sustainable extraction of hazardous metals from crystal glass waste using biodegradable chelating agents
Authors: Mutafela Richard Nasilele , Ye Fei , Jani Yahya , Dutta Joydeep , Hogland William 
Published: January 2022

AbstractExtraction of hazardous metals from dumped crystal glass waste was investigated for site decontamination and resource recovery. Mechanically activated glass waste was leached with biodegradable chelating agents of ethylenediamine-N,N′-disuccinic acid (EDDS) and nitrilotriacetic acid (NTA), where the concentration and reaction time were determined by using Box–Wilson experimental design. Hazardous metals of lead (Pb), arsenic (As), antimony (Sb) and cadmium (Cd) with concentrations higher than regulatory limits were extracted wherein the extraction yield was found to vary Pb > Sb > As > Cd. Extraction was influenced more by type and concentration of chelator rather than by reaction time. A maximum of 64% of Pb could be extracted by EDDS while 42% using NTA. It is found that increase of chelator concentrations from 0.05 M to 1 M did not show improved metal extraction and the extraction improved with reaction time until 13 h. This study provides sustainable alternative for treating hazardous glass waste by mechanical activation followed by extraction using biodegradable chelator, instead of acid leaching.

Thermal analysis of MgFe-Cl Layered doubled hydroxide (LDH) directly synthetized and produced “via memory effect”
Authors: Cardinale Anna Maria , Fortunato Marco , Locardi Federico , Parodi Nadia 
Published: January 2022

AbstractLayered doubled hydroxides (LDHs) are known to be an interesting class of 2D layered materials, with a wide range of possible composition and a flexible structure suitable for topochemical reactions. Thus, LDHs have been applying in different fields, such as catalysis, energy storage and all the applications in which a high exchange capability (of both cations and anions) is required. For remediation purpose, a MgFe-Cl LDH $${[({\mathrm{Mg}}_{0.66}^{2+}{\mathrm{Fe}}_{0.33}^{3+}{\left(\mathrm{OH}\right)}_{2}]}^{0.33+}{({\mathrm{Cl}}_{0.33}^{-})}^{0.33-}$$

. To avoid this problem, LDHs could be also prepared with a rehydration of their calcinated oxide (memory effect). In this work were prepared two samples of MFC: one via coprecipitation (MFC-1 in the following) and one via “memory effect” (MFC-mem in the following). Both the compounds were characterized by means of X-ray powder diffraction (PXRD), Fourier transform infrared spectroscopy (FT-IR) and differential thermal analysis-thermogravimetry (DTA-TG) coupled with evolved gas analysis. The results demonstrated that the synthesis of pure MFC is very difficult, and only a minimum contamination of carbon dioxide led to the formation of the carbonate LDH in a massive way. It was also demonstrated that Mg-Fe LDHs in the presence of carbonate could catalyse the formation of the formic acid (HCOOH) at low temperature (< 300 °C).
Making transparency transparent: a systematic literature review to define and frame supply chain transparency in the context of sustainability
Authors: Schäfer Naemi 
Published: January 2022

AbstractSupply chain transparency and its connection to sustainability is a current topic in supply chain management research. The term supply chain transparency is used very loosely in this discourse. Therefore, this article aims to clarify the understanding of supply chain transparency in the context of sustainability to enable future research. In a content analysis-based literature review, 92 peer-reviewed articles were identified in the intersection of sustainability, supply chains, and transparency. Only 30 articles contained a definition of transparency. Supply chain transparency was used and defined very differently among the researchers. By providing a general definition and framework of sustainable supply chain transparency, the term “supply chain transparency” gains more clarity. Three dimensions of transparency were identified: sustainable supply chain information, involved stakeholders, and perspective. The supply chain transparency research was conducted primarily in the context of the food and apparel industry. Transparency was characterized differently among the industries and was studied with different foci. Furthermore, the review revealed a focus of supply chain transparency research on the social dimension of sustainability. Additionally, a wide range of topics on supply chain transparency has been covered in the existing literature, and opportunities for future research are outlined. Future researchers are also encouraged to define transparency more clearly.
Including maintenance in life cycle assessment of road and rail infrastructure—a literature review
Authors: Liljenström Carolina , Björklund Anna , Toller Susanna 
Published: January 2022

Abstract
Purpose
LCA is increasingly used in infrastructure policy and planning. This study maps approaches used in comparative LCA of road and rail infrastructure to (1) determine the length of the analysis period, (2) estimate the maintenance frequency, and (3) include the effects of climate change on infrastructure performance. A LCA may need to fulfil different requirements in different decision-contexts. The relevance of the approaches for decision-making in policy and procurement is therefore discussed.

Methods
Ninety-two comparative LCAs of road and rail infrastructure published in peer-reviewed journals January 2016–July 2020 were reviewed. Papers were found through a systematic process of searching electronic databases, applying inclusion criteria, and conducting backward and forward snowballing.

Results and discussion
The analysis period was commonly determined based on infrastructure service life. The maintenance frequency was estimated based on current practice, laboratory tests, modelling, or scenarios. The effects of climate change were considered in two papers by comparing results in a control case and in a changed climate. In policy and procurement, current practice approaches are not adapted to innovative solutions or to climate change. Modelling and laboratory tests could improve calculations of the maintenance phase but might have some limitations related to innovative solutions. Scenarios could be readily applied in a policy context; however, in procurement, consistent and generic scenarios should be used.

Conclusions
Results suggest what approaches could be used to account for maintenance in infrastructure LCA depending on the decision-context. The LCA community is suggested to research other approaches than current practice to account for long analysis periods, climate change, and innovative solutions. Additionally, literature not covered here could be reviewed for additional approaches and perspectives. Examples include stand-alone LCAs, method development papers, papers on the individual approaches and decision-contexts, certification systems, standards, and guidelines.
Die jungen Wilden brauchen Führung: Treiber von Innovativität und Zufriedenheit im Arbeitsumfeld innovationsferner Branchen
Authors: Kästner Evelyn , Rudolph Katja 
Published: January 2022

ZusammenfassungDer vorliegende Beitrag in der Zeitschrift „Gruppe. Interaktion. Organisation.“ beantwortet die Frage, wie insbesondere Unternehmen in eher innovationsfernen Branchen wie der Versicherungs- und Energiebranche ihre Arbeitnehmer:innen über alle Altersstufen hinweg so unterstützen können, dass innovatives Verhalten am Arbeitsplatz optimal gefördert wird. Hintergrund ist, dass in den kommenden Jahren zwei Welten aufeinanderprallen: Unternehmen müssen innovativ sein, um im Wettbewerb zu bestehen. New Work als strategischer Ansatz ist dabei in aller Munde. Gleichzeitig steigt das Durchschnittsalter der Beschäftigten, weil qualifizierter Nachwuchs in vielen Bereichen fehlt.In einer quantitativen Online-Befragung wurden auf Basis validierter Skalen Daten zur kreativitätsförderlichen Gestaltung des Arbeitsumfelds, zur Erwartungshaltung an New Work, zum innovativen Verhalten im Arbeitsumfeld und zur Zufriedenheit mit dem Ausschöpfungsgrad des eigenen Innovationspotenzials (Ausschöpfungszufriedenheit) erhoben. Die Antwortenden wurden mithilfe einer K‑Means-Clusteranalyse nach Alter und innovativem Verhalten gruppiert, um im Folgenden die jüngeren Innovativen („Junge Wilde“) mit den älteren Innovativen („Erfahrene Pioniere“) vergleichen zu können.Ein durchaus überraschendes Ergebnis ist, dass „die jungen Wilden“ mehr Führung und Struktur benötigen als „die erfahrenen Pioniere“. Da Innovativität signifikant mit der Ausschöpfungszufriedenheit korreliert, wurden ferner in linearen Regressionsanalysen die Treiber dieser Zufriedenheit im Arbeitsumfeld untersucht. Altersunabhängig führen regelmäßige Schulungen und Übungen zu mehr Zufriedenheit. Jedoch benötigen „die jungen Wilden“ Führung und Unterstützung und kommen mit Projektgruppen weniger gut zurecht. „Die erfahrenen Pioniere“ hingegen benötigen in erster Linie den Willen und die Infrastruktur zum gegenseitigen Austausch. Die Ergebnisse legen daher eine altersabhängige Ausgestaltung des Arbeitsumfelds und des Führungsverhaltens nahe.
Selbstbestimmung und Motivation bei der Projektarbeit – Eine empirische Analyse zum souveränen Arbeitshandeln
Authors: von Garrel Jörg , Düben Ansgar 
Published: January 2022

ZusammenfassungDieser Beitrag der Zeitschrift Gruppe. Interaktion. Organisation. (GIO) stellt zentrale Ergebnisse zweier empirischer Studien zur Selbstbestimmung von Arbeit bzw. Arbeitszeit – im Sinne eines arbeits(zeit)souveränen Handelns – vor, die im Auftrag der Deutschen Gesellschaft für Projektmanagement e. V. in den Jahren 2015 und 2020 durchgeführt wurden.Hintergrund des Beitrages ist der Umstand, dass die fortlaufende digitale Transformation auch die Wissens- und somit die Projektarbeit zunehmend dynamisiert. Arbeitssouveränes Handeln gewinnt dadurch an Bedeutung und stellt neue Anforderungen an die in den Projekten tätigen Wissensarbeiter:innen. Die in diesem Beitrag dargestellten Studienergebnisse beleuchten wesentliche Inhalte zur aktuellen Ausgestaltung der Arbeits(zeit)souveränität, um auf dieser Basis Handlungsempfehlungen für ein motivierendes Arbeitshandeln zu geben. Die Ergebnisse verdeutlichen, dass arbeitssouveränes Handeln unter Mitarbeiter:innen in wissensintensiven Projekten weit verbreitet ist. Gemessen an potenziellen Charakteristika arbeitssouveräner Tätigkeiten (Selbstbestimmtheit, Hierarchiearmut, Zeit- und Ortsunabhängigkeit) arbeiten viele Mitarbeiter:innen „weitgehend“ oder „vollkommen“ arbeitssouverän. In der Selbsteinschätzung ist es ein noch größerer Teil, der die Arbeitstätigkeit als „arbeitssouverän“ einstuft. Diese Tendenz zeichnete sich bereits in der ersten Studie (2015) ab und wird in der aktuellen Untersuchung (2020) bestätigt. Dabei hat die Pandemie-Situation den Grad der Arbeitssouveränität beeinflusst: Die Mitarbeiter:innen arbeiten aktuell orts- und zeitunabhängiger sowie selbstbestimmter als vor der Pandemie. Strukturelle Veränderungen auf Organisationsseite, wie eine Verringerung oder Verflachung von Hierarchien, sind mit diesen Änderungen nicht verbunden.Auf Ebene der Mitarbeiter:innen wird deutlich, dass soziale Eingebundenheit sowie das Erleben von Kompetenz und Autonomie zentrale Grundbedürfnisse selbstbestimmten Handelns sind, die die Motivation der Mitarbeiter:innen signifikant positiv beeinflussen und in Zusammenhang mit der selbstempfundenen Arbeitssouveränität stehen. Somit bestehen potenzielle Stellschrauben für Organisationen, mit Maßnahmen auf der Strukturebene signifikanten Einfluss auf die Handlungsebene und somit die Motivation der Mitarbeiter:innen zu nehmen.Souveräner Umgang mit der eigenen Arbeit und Arbeitszeit wird als sinnstiftend sowie als Anerkennung und Ausdruck von Vertrauen gewertet. In der Folge wächst die individuelle Verantwortung der Mitarbeiter:innen, was zugleich größere Handlungsspielräume verspricht. Der Strukturwandel wird von Mitarbeiter:innen insgesamt tendenziell als positiv angesehen (2015 & 2020).

Published: January 2022

AbstractSerum ferritin (SF) and haemoglobin (Hb) are widely used in clinical practice to assess iron status. Studies exploring the relationship of SF and Hb with atherosclerotic cardiovascular disease (ASCVD) risk have yielded conflicting results, and some indicated sex specificity. Hypertensive patients have abnormal iron status. However, research on patients with hypertension is limited. We aim to investigate the sex-specific links of SF and Hb with the predicted 10-year ASCVD risk in hypertensive patients. This cross-sectional study included 718 hypertensive men and 708 hypertensive women. The predicted 10-year ASCVD risk was calculated based on the China-PAR equation. The dose–response curves were illustrated by fitting linear and quadratic models. In hypertensive men, the iron status fits for a quadratic model for ASCVD risk, showing a U-shape. After adjusting for potential confounding factors, the regression coefficients and 95% confidence intervals (95% CI) across tertile of SF were 0.0 (reference), − 0.99 (− 1.65, − 0.33) and − 0.22 (− 0.88, 0.44), and of Hb were 0.0 (reference), − 0.74 (− 1.41, − 0.08) and − 0.77 (− 1.46, − 0.08). In hypertensive women, iron status was linearly and positively associated with ASCVD risk. Per one unit increment of log-transformed SF as well as Hb was associated with a 1.22 (95% CI: 0.97, 1.48) and 0.04 (95% CI: 0.02, 0.07) increased in ASCVD risk score, respectively. A significant interaction between iron status and inflammation on ASCVD risk was observed in hypertensive women. SF and Hb showed a U-shape with ASCVD risk in hypertensive men; however, a positive linear relationship was observed in hypertensive women.

Abstract
Purpose
The aim the study was to assess the impact of the lockdown due to COVID-19 on diabetes control.

Methods
The HbA1c value from a pre-lockdown visit (V1) from patients with diabetes was compared to the lockdown visit one (V2) after 3–5 months of its duration. Additional information on how the HbA1c changed and which variables can modify HbA1c during lockdown was also studied.

Results
Records from 65 patients (type 2 diabetes −96,9%) were eligible and revealed that: HbA1c was at the target in 60% of the patients at V2 compared to 40% at V1; HbA1c decreased and normalized in 19, but worsened in 4 participants during the lockdown. No impact on HbA1c of: sex, age, diabetes duration, therapy type and modification before the pandemic, abandonment of the treatment, previous problems with glycemic control, or change in body weight and physical activity during the lockdown, was found. The previous macrovascular complications were the only variable that affected the increase in HbA1c (p = 0.0072), OR = 5.33.

Conclusions
The COVID-19 pandemic has not revealed worsened glycemic control in patients with type 2 diabetes, in general. The patients with macrovascular complications turned out to be at risk of the harmful impact of the restrictions on the HbA1c.
Peripartum cardiomyopathy: a global effort to find the cause and cure for the rare and little understood disease

Abstract
In this review, we present our current understanding of peripartum cardiomyopathy (PPCM) based on reports of the incidence, diagnosis and current treatment options. We summarise opinions on whether PPCM is triggered by vascular and/or hormonal causes and examine the influence of comorbidities such as preeclampsia. Two articles published in 2021 strongly support the hypothesis that PPCM may be a familial disease. Using large cohorts of PPCM patients, they summarised the available genomic DNA sequence data that are expressed in human cardiomyocytes. While PPCM is considered a disease predominately affecting the left ventricle, there are data to suggest that some cases also involve right ventricular failure. Finally, we conclude that there is sufficient evidence to warrant an RNAseq investigation and that this would be most informative if performed at the cardiomyocytes level rather than analysing genomic DNA from the peripheral circulation. Given the rarity of PPCM, the combined resources of international human heart tissue biobanks have assembled 30 ventricular tissue samples from PPCM patients, and we are actively seeking to enlarge this patient base by collaborating with human heart tissue banks and research laboratories who would like to join this endeavour.
Evaluation of Thermal anomaly Preceding Northern Red Sea Earthquake, the 16th June 2020
Authors: Mohamed Emad K. , Elrayess Medhat , Omar Khaled 
Published: January 2022

AbstractOn the 16th June, 2020, a moderate earthquake (Mw = 5.2) hit the Northern Red Sea region, Egypt, that was felt throughout the Hurghada and Sharm El-Sheikh cities and the surrounding areas without any damages. The thermal anomaly before the earthquakes was widely studied with satellite data, such as NOAA/AVHRR and MODIS. The case study aims to monitor and demonstrate the possibility of any variation of the thermal anomaly of sea surface temperature (SST) before and after the 16th June 2020 earthquake and to correlate the results with the previous heat flow study (deep thermal action). The Daytime/Nighttime (SST) data are retrieved from the OBPG serves as a Distributed Active Archive Center (OB. DAAC). The outputs indicated a thermal anomaly on the June 12th, 2020 a few days before the earthquake, covered a large area around the epicenter 60 km impact area, and reached a high value on the 15th June 2020, one day before the earthquake. For the deep thermal action of the entire crust, the earthquake frequency distributions presumed from the reviewed catalogue indicated that the peak of the seismicity is concentrated close to the center of the rift axis in the Northern Red Sea. The heat flow measurements are increased toward the center of the Red Sea rift and decreased toward both sides, generating some partial melt of the rocks and producing crustal subsidence at the center of the Red Sea rift. These results are compatible with the pattern of the seismic activity and heat flow effect around the epicenter. It could be considered as a short-term precursor of the earthquake.
