Introduction to the Law of Benefit Corporations and Other Public Purpose-Driven Companies
Authors: Cebriá Luis Hernando
Published: December 2022

In recent years, the benefit corporation phenomenon has extended from many US jurisdictions to other countries. Benefit corporations are an expression of the principles of corporate social responsibility in company law through the creation of companies aiming at an enlightened value, for not only the shareholders but the stakeholders. However, different forms of corporations serve this purpose in the United States and in European and Latin American countries. Some are more proximate to non-profit entities, while others, more recently, to the North American model of the benefit corporation. This chapter reviews the current trends in company law that refer to these special legal forms, along with the regime of “public-interest entities” in the European Union and the institutional perspective maintained in some of its jurisdictions. To this end, this chapter analyzes the different legal forms of adaptation of the basic features of benefit corporations and other public purpose-driven companies to the regulatory environment in each jurisdiction.
Purpose-Driven Companies and the Projected Legal System for Benefit and Collective Interest Companies in Chile
Authors: Alcalde Silva Jaime
Published: December 2022

This chapter describes the situation of purpose-driven companies in Chile and the system for benefit and collective interest companies, which have been discussed in Congress since 2017. This requires contextualizing the reception of certified B Corps in the country since 2012 and the different bills that have been presented to regulate them. Only one of them has prospered, although without positive results thus far.
Benefit Corporations in the Peruvian Legal Ecosystem
Authors: Mujica Filippi Juan Diego , Ochoa Pérez Claudia
Published: December 2022

In 2020, Peru became the third country in Latin America to adopt the benefit corporation model into its legal system, following its neighbors, Colombia and Ecuador, in proposing a legal model to identify purpose-driven companies. The Peruvian “sociedad de beneficio e interés colectivo” or a BIC company has not only been influenced by the U.S. Model Benefit Corporation Legislation but also by its legal exports, such as the Italian società benefit, the Colombian BIC law, and the Argentinean BIC draft bill. The Peruvian benefit corporation legal ecosystem consists of several newly approved legal documents, such as the law itself, its regulation, and the related reporting guidelines. The law allows the corporate models regulated by the Corporate Act to include three main features: (i) a specific social and environmental purpose in the bylaws; (ii) higher duties and protection for managers and directors; and (iii) transparency and reporting requirements. Additionally, the law grants supervisory power to the Peruvian Competition Authority and oversight of the legal ecosystem to the Peruvian Ministry of Industry. The regulations and reporting guidelines detail these three main features, particularly regarding the companies’ purpose and the transparency and reporting requirements. Only a year after the introduction of the BIC legal ecosystem in Peru, there is an on-going public-private effort to implement the law widely for corporations to actively contribute to the Sustainable Development Goals.
Modular conjugations in 2D conformal field theory and holographic bit threads
Authors: Mintchev Mihail , Tonni Erik
Published: December 2022

Abstract

We study the geometric action of some modular conjugations in two dimensional (2D) conformal field theories. We investigate the bipartition given by an interval when the system is in the ground state, either on the line or on the circle, and in the thermal Gibbs state on the line. We find that the restriction of the corresponding inversion maps to a spatial slice is obtained also in the gauge/gravity correspondence through the geodesic bit threads in a constant time slice of the dual static asymptotically AdS background. For a conformal field theory in the thermal state on the line, the modular conjugation suggests the occurrence of a second world which can be related through the geodesic bit threads to the horizon of the BTZ black brane background. An inversion map is constructed also for the massless Dirac fermion in the ground state and on the line bipartite by the union of two disjoint intervals.
Three Centuries of Appendicectomy
Authors: Herrod Philip J. J. , Kwok Alex T. , Lobo Dileep N.
Published: December 2022

Background

Save for the contribution of Charles McBurney, who described his eponymous point and the appendicectomy incision, the history of appendicectomy is largely unknown among the medical profession. This review traces the history from the first anatomical depiction of the appendix to the development of open appendicectomy and the recent minimally invasive and non‐operative methods.

Methods

Historical articles, monographs and books containing anatomical descriptions of the vermiform appendix and reports of appendicitis and its surgical treatment were retrieved after searching the PubMed, Google Scholar and Embase databases from their inception to 31 March 2022.

Results

The first inadvertent appendicectomy was performed during an operation for a groin hernia by Cookesley in 1731, and Mestivier was the first to drain a right iliac fossa abscess, due to appendicitis, in 1757. Krönlein performed the first appendicectomy for acute appendicitis in 1884 but his patient died. The first successful appendicectomy for acute appendicitis leading to patient survival was by Morton in 1887. In 1976, Wirschafter and Kaufman performed an inadvertent colonoscopic appendicectomy and, in 1980, Semm carried out the first laparoscopic appendicectomy. The first appendicectomy via a natural orifice (transgastric) appendicectomy was by Rao and Reddy in 2004.

Conclusion

This historical review charts the development of surgical knowledge concerning the management of appendicitis, from the first anatomical drawings of the appendix and descriptions of appendicitis to the development of surgical and conservative treatments up to the present day. It also corrects some inaccuracies of attribution in previous historical reviews.

Published: December 2022

Objectives

To construct effective prediction models for neoadjuvant radiotherapy (RT) and targeted therapy based on whole-tumor texture analysis of multisequence MRI for soft tissue sarcoma (STS) patients.

Methods

Thirty patients with STS of the extremities or trunk from a prospective phase II trial were enrolled for this analysis. All patients underwent pre- and post-neoadjuvant RT MRI examinations from which whole-tumor texture features were extracted, including T1-weighted with fat saturation and contrast enhancement (T1FSGd), T2-weighted with fat saturation (T2FS), and diffusion-weighted imaging (DWI) sequences and their corresponding apparent diffusion coefficient (ADC) maps. According to the postoperative pathological results, the patients were divided into pathological complete response (pCR) and non-pCR (N-pCR) groups. pCR was defined as less than 5% of residual tumor cells by postoperative pathology. Delta features were defined as the percentage change in a texture feature from pre- to post-neoadjuvant RT MRI. After data reduction and feature selection, logistic regression was used to build prediction models. ROC analysis was performed to assess the diagnostic performance.

Results

Five of 30 patients (16.7%) achieved pCR. The Delta_Model (AUC 0.92) had a better predictive ability than the Pre_Model (AUC 0.78) and Post_Model (AUC 0.76) and was better than AJCC staging (AUC 0.52) and RECIST 1.1 criteria (AUC 0.52). The Combined_Model (pre, post, and delta features) had the best predictive performance (AUC 0.95).

Conclusion

Whole-tumor texture analysis of multisequence MRI can well predict pCR status after neoadjuvant RT and targeted therapy in STS patients, with better performance than RECIST 1.1 and AJCC staging.

Key points

• MRI multisequence texture analysis could predict the efficacy of neoadjuvant RT and targeted therapy for STS patients.

• Texture features showed incremental value beyond routine clinical factors.

• The Combined_Model with features at multiple time points showed the best performance.

Recent studies using convection-permitting (CP) climate simulations have demonstrated a step-change in the representation of heavy rainfall and rainfall characteristics (frequency-intensity) compared to coarser resolution Global and Regional climate models. The goal of this study is to better understand what explains the weaker frequency of precipitation in the CP ensemble by assessing the triggering process of precipitation in the different ensembles of regional climate simulations available over Europe. We focus on the statistical relationship between tropospheric temperature, humidity and precipitation to understand how the frequency of precipitation over Europe and the Mediterranean is impacted by model resolution and the representation of convection (parameterized vs. explicit). We employ a multi-model data-set with three different resolutions (0.44°, 0.11° and 0.0275°) produced in the context of the MED-CORDEX, EURO-CORDEX and the CORDEX Flagship Pilot Study "Convective Phenomena over Europe and the Mediterranean" (FPSCONV). The multi-variate approach is applied to all model ensembles, and to several surface stations where the integrated water vapor (IWV) is derived from Global Positioning System (GPS) measurements. The results show that all model ensembles capture the temperature dependence of the critical value of IWV (IWVcv), above which an increase in precipitation frequency occurs, but the differences between the models in terms of the value of IWVcv, and the probability of its being exceeded, can be large at higher temperatures. The lower frequency of precipitation in convection-permitting simulations is not only explained by higher temperatures but also by a higher IWVcv necessary to trigger precipitation at similar temperatures, and a lower probability to exceed this critical value. The spread between models in simulating IWVcv and the probability of exceeding IWVcv is reduced over land in the ensemble of models with explicit convection, especially at high temperatures, when the convective fraction of total precipitation becomes more important and the influence of the representation of entrainment in models thus becomes more important. Over lowlands, both model resolution and convection representation affect precipitation triggering while over mountainous areas, resolution has the highest impact due to orography-induced triggering processes. Over the sea, since lifting is produced by large-scale convergence, the probability to exceed IWVcv does not depend on temperature, and the model resolution does not have a clear impact on the results.
Alternative Behandlungsverfahren bei Vorhofflimmern

Published: December 2022

Vorhofflimmern, die häufigste anhaltende Herzrhythmusstörung, ist mit einer erheblichen Morbidität, Mortalität und Inanspruchnahme von Gesundheitsleistungen verbunden. Vor dem Hintergrund, dass die zur Rhythmuskontrolle bei Vorhofflimmern eingesetzten Verfahren (Katheterablation, Antiarrhythmika) mit einer Reihe von Einschränkungen und Risiken behaftet sind, besteht ein wachsendes Interesse an erweiterten Behandlungsstrategien. Hierzu gehören eine Optimierung des Lebensstils, die Einstellung von Risikofaktoren für Vorhofflimmern und alternative Behandlungsverfahren, wie z. B. Yoga. Zu dessen Wirkung bei Vorhofflimmern liegen bislang nur wenige Studien vor. Diese sprechen aber dafür, das Yoga tatsächlich in der Lage sein dürfte, die Häufigkeit der Rhythmusstörung und ihre Progression zu vermindern. Auch die Risikofaktoren für Vorhofflimmern und die Lebensqualität werden positiv beeinflusst. Da unerwünschte Effekte und Komplikationen bei kompetenter Anleitung selten sind, kann regelmäßiges Yoga jetzt schon empfohlen werden. Um eindeutige, evidenzbasierte, praktische Empfehlungen geben zu können, sind aber weitere klinische Studien notwendig.
Loss of shallow water physiotope areas in tidal estuaries of the North Sea since the nineteenth century
Authors: Hamer Kay , Cutts Nick , Liedtke Nick , Roose Frederik
Published: December 2022

Purpose

The main aim of this study was to quantify changes in shallow water physiotopes in the North Sea estuaries of Elbe, Humber, Scheldt, and Weser and to collect information on engineering activities which influenced the estuarine hydrology and potentially the spatial range of physiotopes, both between the nineteenth century and present day. A second aim was to provide a database on the recent physiotope distribution for the assessment of future interventions on these estuaries.

Methodically

Physiotopes were defined by water depth and salinity. The area of the sub-, supra-, and intertidal physiotopes was calculated from digitised maps from different times since the nineteenth century. The spatial changes were opposed to the dates of implementation of the hydraulic engineering activities.

Results

From the nineteenth century onwards, the shallow water physiotopes of Elbe, Sea Scheldt, and Weser decreased spatially between 4 and 30%, whereas for the Humber estuary the areas have remained stable. The loss of areas was particularly located in the inner estuaries and concerned mostly freshwater physiotopes. The oligohaline and mesohaline zones exhibited less of a reduction in size, although, in the same order of magnitude, while the area of polyhaline physiotopes remained nearly unchanged.

Conclusion

The loss of physiotopes which occurred mainly in the freshwater and oligohaline zones is important because physiotopes host different salinity-dependent biological communities. This loss of physiotopes could be observed after the implementation of hydraulic engineering projects, which could have led to higher current velocities, further upstream tidal penetration and very likely a corresponding shift of the salt-/freshwater interface upstream. All these effects altered the physiotope areas of the estuaries, except of the Humber estuary. The Humber had been modified to its today’s shape essentially before the nineteenth century. Nevertheless, the data describing the recent size of physiotopes provide a reference base for the assessment of future interventions in the estuaries of Elbe, Humber, Sea Scheldt, and Weser.

Published: December 2022

Recent investments in built environment infrastructure to create healthy communities have highlighted the need for equity and environmental justice. Although the benefits of healthy community design (e.g., connecting transportation systems and land use changes) are well established, some reports suggest that these changes may increase property values. These increases can raise the risk of displacement for people with low incomes and/or who are from racial and ethnic minority groups, who would then miss out on benefits from changes in community design. This review scanned the literature for displacement mitigation and prevention measures, with the goal of providing a compilation of available strategies for a wide range of audiences including public health practitioners. A CDC librarian searched the Medline, EbscoHost, Scopus, and ProQuest Central databases, and we identified grey literature using Google and Google Scholar searches. The indexed literature search identified 6 articles, and the grey literature scan added 18 articles. From these 24 total articles, we identified 141 mitigation and prevention strategies for displacement and thematically characterized each by domain using an adapted existing typology. This work provides a well-categorized inventory for practitioners and sets the stage for future evaluation research on the implementation of strategies and practices to reduce displacement.
Role of Omega-3 Fatty Acids in Cardiovascular Disease: the Debate Continues
Authors: Sherratt Samuel C. R. , Libby Peter , Budoff Matthew J. , Bhatt Deepak L. , Mason R. Preston
Published: December 2022

Purpose of Review

The omega-3 fatty acids (n3-FAs), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), have recently undergone testing for their ability to reduce residual cardiovascular (CV) risk among statin-treated subjects. The outcome trials have yielded highly inconsistent results, perhaps attributable to variations in dosage, formulation, and composition. In particular, CV trials using icosapent ethyl (IPE), a highly purified ethyl ester of EPA, reproducibly reduced CV events and progression of atherosclerosis compared with mixed EPA/DHA treatments. This review summarizes the mechanistic evidence for differences among n3-FAs on the development and manifestations of atherothrombotic disease.

Recent Findings

Large randomized clinical trials with n3-FAs have produced discordant outcomes despite similar patient profiles, doses, and triglyceride (TG)-lowering effects. A large, randomized trial with IPE, a prescription EPA only formulation, showed robust reduction in CV events in statin treated patients in a manner proportional to achieved blood EPA concentrations. Multiple trials using mixed EPA/DHA formulations have not shown such benefits, despite similar TG lowering. These inconsistencies have inspired investigations into mechanistic differences among n3-FAs, as EPA and DHA have distinct membrane interactions, metabolic products, effects on cholesterol efflux, antioxidant properties, and tissue distribution. EPA maintains normal membrane cholesterol distribution, enhances endothelial function, and in combination with statins improves features implicated in plaque stability and reduces lipid content of plaques.

Insights into reductions in residual CV risk have emerged from clinical trials using different formulations of n3-FAs. Among high-risk patients on contemporary care, mixed n3-FA formulations showed no reduction in CV events. The distinct benefits of IPE in multiple trials may arise from pleiotropic actions that correlate with on-treatment EPA levels beyond TG-lowering. These effects include altered platelet function, inflammation, cholesterol distribution, and endothelial dysfunction. Elucidating such mechanisms of vascular protection for EPA may lead to new interventions for atherosclerosis, a disease that continues to expand worldwide.
Dysfunctional Attitudes Toward Motherhood and Depressive Symptoms in Portuguese Pregnant Women During COVID-19 Pandemic: the Mediating Roles of Self-Compassion and Mindful Self-Care
Authors: Xavier Sandra , Branquinho Mariana , Pires Raquel , Moreira Helena , Coelho Maria , Araújo-Pedrosa Anabela
Published: December 2022

Objectives

There is evidence that the coronavirus disease 2019 (COVID-19) pandemic had a negative impact on the mental health of pregnant women, such as an increase in the prevalence of depression. Given the negative consequences that depressive symptoms can pose for pregnant women, it is crucial to understand how cognitive processes influence women’s depressive symptoms during the COVID-19 pandemic among this specific vulnerable population. The present study aimed to examine the relationship between pregnant women’s dysfunctional attitudes toward motherhood and their depressive symptoms, considering the mediating roles of self-compassion and mindful self-care.

Method

A cross-sectional online survey was conducted in Portugal between October 2020 and April 2021. A sample of 244 pregnant women answered a set of questionnaires to assess dysfunctional attitudes toward motherhood, depressive symptoms, self-compassion, and mindful self-care.

Results

More dysfunctional attitudes toward motherhood were associated with higher levels of depressive symptoms, and this relation was mediated through self-compassion and mindful self-care.

Conclusions

These results highlight that self-compassion and mindful self-care are important psychological mechanisms and the importance of considering them in psychological interventions to prevent and/or treat depressive symptoms in pregnant women with dysfunctional attitudes toward motherhood during stressful events such as a pandemic.
Geochemistry and organic petrology of the bituminite shales from the Kapurdi mine, Rajasthan of NW India: implications for waxy oil generation potential

Published: December 2022

This study examines the geochemical and petrographic characteristics of seven bituminite shales from the Kapurdi mine in the Rajasthan, NW India, in order to assess their organic matter inputs and evaluate the oil-prone potentials. These bituminite shale samples exhibit high total organic carbon (TOC) content (up to 45.11 wt.%). The high TOC contents were correlated with low total sulfur content of less than 1 wt.% and suggest that these bituminite shales were deposited in a fresh lacustrine environment. The dominance of such lacustrine environmental setting was confirmed by the presence of the Botryococcus algae. The analyzed bituminite shales are characterized by a bimodal distribution of normal alkanes and relatively low isoprenoid Pr/Ph, Pr/n-C17 and Ph/n-C18 ratios. These characteristics suggest that these bituminite shales contain a blend of organic matter that was derived primarily from algal lacustrine and other aquatic organic matter, with terrigenous land plants and deposited under suboxic to anoxic environmental conditions. Such findings of the organic matter (OM) input and environmental conditions are consistent with mainly Types I and II kerogen and small amounts of Type II/III kerogen, thus yielding both oil and gas prone to higher concentrations of oil generation potential. The dominance of hydrogen-rich kerogen and oil generation potential is in agreement with the findings of high hydrogen index (HI = 240–425 mg HC/g TOC) and H/C atomic ratio of more than 1.20. The abundance of n-alkene and n-alkane doublets in the pyrolysis–gas chromatography (Py–GC) also indicates that these bituminite shales have potential to generate high concentrations of paraffinic waxy oil. Most of the maturity indicators show that the bituminite shales from the Kapurdi mine have not yet entered the main stage of oil generation window, exhibiting a range of immature stages. Therefore, as highlighted in this study, these bituminite shales can be considered as a good candidate for oil shale reoterting processes to release commercial amounts of oil upon using artificial heating techniques such as hydrothermal conversion.
Legislative hurdles to using traditional domestic livestock in rewilding programmes in Europe
Authors: Pérez-Barbería F. Javier , Gómez J. Angel , Gordon Iain J.
Published: December 2022

Rewilding is a restoration strategy that aims to return anthropogenic ecosystems to a “self-organized” state, by reinstating trophic complexity through disturbance (e.g. predation, herbivory), dispersal and connectivity. In depopulated areas of Europe, lite versions of rewilding, that maintain but minimize the management of rewilding species (e.g. predators, large herbivores) is gaining support. Livestock rewilding (LR) is a form of rewilding-lite, that uses livestock landraces as keystone species in the restoration of herbivory (the functional integrity of ecosystems) offering ecosystem services, such as ecotourism and the sale of livestock population surpluses, that can mitigate the economic and social effects of rural depopulation. Many challenges remain to implementing LR, including (i) more empirical evidence is required of the feasibility of LR across a variety of habitats and conditions, and (ii) understanding the hurdles that legislation poses for LR, the latter being the aim of this study. To accomplish this, we reviewed the EU legislation on environmental protection, animal health and welfare, identification and traceability, and ownership and civil responsibility, to assess how this might apply to LR. Although there is no specific EU legislation prohibiting LR, the review indicates that it is not clear what legislation applies to LR, as LR’s status lies between that of livestock and wild species. As such the existing legislation can be a serious impediment to the development of LR programmes. We highlight the needs for a legal definition, and status of LR species and their ownership. We propose ways to adapt this legislation to support the application of LR programmes in abandoned areas of EU, for example, by using legal exceptions intended for livestock under extensive animal farming systems.
Exklusives Flüchtlingsschutzregime, koloniale „Andere“ und Geschlechterdichotomien
Authors: Jaji Rose , Krause Ulrike
Published: December 2022

Obwohl das internationale Flüchtlingsrecht und der Flüchtlingsschutz vorgeben, für alle als Flüchtlinge kategorisierten Menschen weltweit zu gelten, ist deren Entstehung und Anwendung auf das Engste mit den geopolitischen Kämpfen der Großmächte verbunden. Infolgedessen sind unterschiedliche Konzeptualisierungen von Flüchtlingen entlang der globalen Nord-Süd-Linie entstanden. Der Beitrag interessiert sich für koloniales Othering im Kontext von Fluchtmigration und verknüpft analytisch drei Bereiche: das internationale Flüchtlingsrecht, die politischen Diskurse über Flüchtlingsschutz und die geschlechtsspezifischen Auswirkungen auf Flüchtlinge, insbesondere im postkolonialen Afrika. Wir zeigen, dass der ursprüngliche Fokus der Genfer Flüchtlingskonvention von 1951 auf Flüchtlinge in Europa zur strukturellen Vernachlässigung und zum Othering von Flüchtlingen beigetragen hat, die ‚anderswo‘ in der Welt situiert waren. Während und nach der Dekolonisierung in Afrika haben politische Diskurse über Schutz diese Dynamiken intensiviert; der Schwerpunkt lag nicht auf rechtlichem Asyl, sondern auf humanitärer Hilfe. Dadurch wurden die ‚anderen‘ Flüchtlinge als hilfsbedürftig, apolitisch und feminin dargestellt, was westliche Geschlechterdichotomien (re)produzierte.
Gestörter Empfang: Putins Kriegsnarrative und die deutsche Russlandpolitik
Authors: Schneckener Ulrich
Published: December 2022

Der Beitrag beschäftigt sich mit der Frage, wie es in der deutschen Politik zu der Fehleinschätzung von Putins Absichten kam und warum bestimmte Signale des Kremls nicht ausreichend wahrgenommen wurden. Dabei wird die These verfolgt, wonach die Leitlinien der deutschen Russlandpolitik jahrzehntelang wie ein Wahrnehmungsfilter wirkten, durch den nur jene Botschaften aus Russlands Führung drangen, die mit den eigenen Prämissen und Vorstellungen halbwegs im Einklang standen. Von den drei Kriegsnarrativen Putins wurde primär jenes der „westlichen Hegemonie“ bzw. der „NATO-Expansion“ wahrgenommen, was zu einer Verstärkung der eigenen Glaubenssätze im Umgang mit Russland führte und nicht zu deren kritischer Überprüfung.

Authors: DeBate Rita , Gatto Amy , Rafal Gregor , Bleck Jennifer
Published: December 2022

Although the number of students receiving care from college counseling centers has increased, engaging male college students to seek help presents a unique challenge. This qualitative study explored mental health literacy and help-seeking behaviors among undergraduate college men. Semi-structured interviews (n = 26) based on three vignettes (anxiety, depression, stress) were employed to assess mental health literacy. Analysis revealed three general themes and associated sub-themes: (a) knowledge of signs and symptoms (physiological, behavioral, and emotional); (b) recommended help-seeking behaviors (do nothing, self-care, seek help); and (c) barriers to help-seeking (social stigma, self-stigma, masculinity). Findings present a triadic interplay between the person, help-seeking behavior, and environment. Future research should explore this dynamic relationship to inform interventions aimed at improving college male mental health help-seeking behavior.
Air oxidation in surface engineering of biochar-based materials: a critical review
Authors: Sun Zhuozhuo , Dai Lichun , Lai Penghui , Shen Feng , Shen Fei , Zhu Wenkun
Published: December 2022

Biochar always suffers from low porosity and/or poor surface functionality, which limit its performances. Among various surface engineering strategies, air oxidation favors both pore development and surface oxygenation for biochar. However, there is still a lack of systematic knowledge and critical perspective on air oxidation in surface engineering of biochar-based materials for various applications. Herein, this review analyzed the mechanisms of air oxidation, summarized the routes of air oxidation in surface engineering of biochar-based materials, investigated the impacts of controlling factors (including operation parameters and intrinsic biochar structure) on pore development and surface oxygenation during air oxidation, and discussed the performances of the resultant materials in pollution control, biomass catalytic conversion and energy storage. This review suggested that air oxidation could be conducted in oxidative torrefaction/pyrolysis, and applied as post-modification or pretreatment processes. Interestingly, air oxidation is efficient in enriching the heteroatoms in the heteroatom-doped biochar, and promoting the doping of metal species on biochar by enriching the anchor sites. This review also highlighted the future challenges concerning air oxidation in the surface engineering of biochar-based materials. Finally, this review was intended to attract broad attention and inspire new discoveries for promoting the application of air oxidation in surface engineering of biochar-based materials for various advanced applications.

Employee voice: a knowledge map to provide conceptual clarity and future research directions
Authors: Mori Martina , Cavaliere Vincenzo , Sassetti Sara , Caputo Andrea
Published: December 2022

The increasing globalisation, the multiculturality of workplaces and the current challenges for organisations generated the need for researchers to support them to manage the workforce. Although the relevance of employee voice for these themes, a lack of shared understanding about this topic results in fragmented literature across and within research fields that limits theoretical advancement and deep comprehension of the phenomenon. Our first aim is to offer a literature review of employee voice by combining systematic and bibliometric methods; the second aim is to understand voice's main issues and implications by considering different research streams. The results present an integrated framework of the leading intellectual knowledge and reveal the main research focuses on voice in domestic contexts. The discussion underlines the cultural issue and context as critical elements for future research by proposing avenues for scholars and some implications for organisations to benefit from the contributions of their members.
Protein acylation: mechanisms, biological functions and therapeutic targets
Authors: Shang Shuang , Liu Jing , Hua Fang
Published: December 2022

Metabolic reprogramming is involved in the pathogenesis of not only cancers but also neurodegenerative diseases, cardiovascular diseases, and infectious diseases. With the progress of metabonomics and proteomics, metabolites have been found to affect protein acylations through providing acyl groups or changing the activities of acyltransferases or deacylases. Reciprocally, protein acylation is involved in key cellular processes relevant to physiology and diseases, such as protein stability, protein subcellular localization, enzyme activity, transcriptional activity, protein–protein interactions and protein–DNA interactions. Herein, we summarize the functional diversity and mechanisms of eight kinds of nonhistone protein acylations in the physiological processes and progression of several diseases. We also highlight the recent progress in the development of inhibitors for acyltransferase, deacylase, and acylation reader proteins for their potential applications in drug discovery.
Discovery of two-dimensional binary nanoparticle superlattices using global Monte Carlo optimization
Authors: Zhou Yilong , Arya Gaurav
Published: December 2022

Binary nanoparticle (NP) superlattices exhibit distinct collective plasmonic, magnetic, optical, and electronic properties. Here, we computationally demonstrate how fluid-fluid interfaces could be used to self-assemble binary systems of NPs into 2D superlattices when the NP species exhibit different miscibility with the fluids forming the interface. We develop a basin-hopping Monte Carlo (BHMC) algorithm tailored for interface-trapped structures to rapidly determine the ground-state configuration of NPs, allowing us to explore the repertoire of binary NP architectures formed at the interface. By varying the NP size ratio, interparticle interaction strength, and difference in NP miscibility with the two fluids, we demonstrate the assembly of an array of exquisite 2D periodic architectures, including AB-, AB2-, and AB3-type monolayer superlattices as well as AB-, AB2-, A3B5-, and A4B6-type bilayer superlattices. Our results suggest that the interfacial assembly approach could be a versatile platform for fabricating 2D colloidal superlattices with tunable structure and properties.
An L-band emitter with quantum memory in silicon
Authors: Udvarhelyi Péter , Pershin Anton , Deák Péter , Gali Adam
Published: December 2022

Fluorescent centres in silicon have recently attracted great interest, owing to their remarkable properties for quantum technology. Here, we demonstrate that the C-centre in silicon can realise an optically readable quantum register in the L-band wavelength region where the transmission losses in commercial optical fibres are minimal. Our in-depth theoretical characterisation confirms the assignment of the C-centre to the carbon-oxygen interstitial pair defect. We further explore its magneto-optical properties, such as hyperfine and spin-orbit coupling constants from first principles calculations, which are crucial for tight control of the quantum states of the triplet electron spin. Based on this data, we set up quantum optics protocols to initialise and read out the quantum states of the electron spin, and realise a quantum memory by transferring quantum information from the electron spin to proximate 29Si nuclear spins. Our findings establish an optically readable long-living quantum memory in silicon where the scalability of qubits may be achieved by CMOS-compatible technology.

Adverse birth outcomes are a common cause of health problems in developing nations and have a significant negative impact on infant health as well as financial costs to families, communities, and the world. Mothers with HIV may be at increased risk of adverse birth outcomes. However, there is a limited study about adverse birth outcomes among mothers with HIV around the world including in Ethiopia. Therefore this study aimed to assess adverse birth outcomes and associated factors among mothers with HIV Facility based cross-sectional study was conducted among mothers with HIV who gave birth in northwest Amhara region referral hospitals from September 2016 to September 2019. Simple random sampling was used to select 590 mothers. Bivariable and multivariable logistic regressions were carried out to identify factors. Statistical significance was declared by using a p-value < 0.05. An adjusted odds ratio was used to show the magnitude of the association. Out of a total of 590 mothers, the prevalence of adverse birth outcomes among HIV-positive mothers was 21% (95% CI 17.8–24.6%). History of spontaneous abortion [AOR = 1.9, 95% CI (1.19, 3.70)], PROM [AOR = 3.55, 95% CI (1.72, 7.30)], opportunistic infection [AOR = 3.38, 95% CI (1.50, 8.22)], pre-pregnancy BMI of < 18.5 [AOR = 5.61, 95% CI (1.97, 15.91)], MUAC < 23 cm [AOR = 2.56, 95% CI (1.10, 5.97)], and ANC visit of < 4 times [AOR = 3.85, 95% CI (2.34, 6.55)] were significantly associated with Adverse birth outcome. The prevalence of adverse birth outcomes was high. Abortion history, MUAC, BMI, Opportunistic infection, PROM, and a number of ANC visits were associated with adverse birth outcomes.

Nonlinear distortion (noise) limits many communication systems, demanding a means of estimating system performance via device nonlinear characteristics. The noise power ratio (NPR) method which was proposed in 1971 solves this problem for systems with Gaussian stimuli or with special nonlinearity, but practical and accurate methods for many communication systems with non-Gaussian stimuli are rare. Here we propose a probability-maintained (PM) NPR method to accurately measure the spectrum of nonlinear noise via a spectrum analyzer in non-specific systems, including systems with non-Gaussian stimuli. Using an equivalent additive noise model in which the spectrum of equivalent nonlinear noise is the measurement result of PM NPRs, nonlinear system performance could be estimated with an error of 0.5 dB. Further, we find that zero-mean Chi-square noise, instead of Gaussian noise, should be selected for large memory and low-order nonlinear systems. Our method is verified in seven different scenarios with various nonlinear mechanisms and communication applications.

Published: December 2022

Purpose:

Perceived sound quality was variously compared between either no aiding or aiding with three models of hearing aid that varied the microphone position around the pinna, depth of the receiver in the auditory meatus, degree of meatal occlusion, and processing sophistication. The hearing aids were modern designs and commercially available at the time of testing.

Method:

Binaural recordings of multichannel spatially separated speech and music excerpts were made in a manikin, either open ear or aided. Recordings were presented offline over wide-bandwidth, high-quality insert earphones. Participants listened to pairs of the recordings and made preference ratings both by clarity and externality (a proxy for “spaciousness”). Two separate groups of adults were tested, 20 with audiometrically normal hearing (NH) and 20 with mild-to-moderate sensorineural hearing loss (hearing impaired [HI]).

Results:

For ratings of speech clarity, the NH group expressed no preference between the open ear and a deeply inserted occluding aid, both of which were preferred to a low-pass filtered output of the same aid. For the music signal, a small preference emerged for the open-ear recording over that of the aid. For the HI group, clarity of the deeply inserted aid was similar to in-the-ear and behind-the-ear devices for speech, but worse for music. Ratings of spaciousness produced no clear result in either group, which can be attributed to study limitations and/or participant factors.

Conclusion:

Based on clarity, a wide bandwidth, particularly to beyond 5 kHz generally and below 300 Hz for music, is desirable, independent of hearing aid design.
Speech-Language Pathologists' Views of Using Virtual Reality for Managing Cognitive-Communication Disorders Following Traumatic Brain Injury

Published: December 2022

Purpose:

Using virtual reality (VR) to support rehabilitation is an emerging area of research that may offer people with communication disorders a stable and safe communication environment to practice their communication skills. There are currently no VR applications that have been designed to assess or treat cognitive-communication disorders (CCDs) following traumatic brain injury (TBI). Therefore, this study aimed to explore the views of speech-language pathologists (SLPs) who work with people who have a TBI to generate ideas and considerations for using VR in rehabilitation for CCDs. VR researchers were included to provide expert advice about VR technology.

Method:

A total of 14 SLPs and three VR specialists participated in an online interview or focus group. Semistructured discussions explored participants' perspectives related to potential ideas for VR use and any perceived barriers and facilitators to VR implementation for managing CCDs following TBI. Data were video- and audio-recorded, transcribed, and analyzed qualitatively using thematic analysis.

Results:

Three main themes were generated from thematic analysis: VR is a tool that could enhance clinical practice, the need to consider and navigate potential red flags, and solutions to pave the way forward. Suggestions to overcome perceived barriers to VR use were also provided.

Discussion:

Participants expressed interest in using VR for rehabilitation of CCDs following TBI. However, potential barriers and risks to use should be considered prior to implementation. The findings offer guidance to support future research and development of VR in this field.

Temporal prediction for spectrum environment maps with moving radiation sources

Published: December 2022

Spectrum resources are becoming harder to come by for wireless communications. The spectrum environment map (SEM), which depicts the electromagnetic environment's current state and future trend, is a valuable technique for managing and allocating spectrum resources. Most SEM construction approaches only take static SEMs into account and cannot forecast time‐domain changes and trends of SEMs in dynamic scenes. In this paper, a brand‐new temporal SEM prediction method for the high dynamic spectrum environment is proposed. This method is based on knowledge of radiation source and the optical flow driven by propagation channel models. First, a novel radiation source localization strategy is designed to obtain the radiation source movement information. Then, the optical flow field of the available SEMs is combined with the information regarding radiation source movement. In order to forecast future SEMs, a propagation model driven reconstruction technique is developed. Simulation findings demonstrate how well the suggested strategy is tailored to capture the spatiotemporal correlation of SEMs. This technique performs better than the state‐of‐the‐art in terms of single‐ and multiple‐step SEM predictions.
Dysphagie bei tracheotomierten Patienten nach Langzeitbeatmung
Authors: Heidler M.-D.
Published: December 2022

Unabhängig von der Art der kritischen Erkrankung haben tracheotomierte Patienten ein hohes Risiko für die Entwicklung einer Schluckstörung. Diese ist potenziell lebensbedrohlich, da sie zu Aspiration und Pneumonie führen kann. Vor einer oralen Nahrungsgabe sollte daher unbedingt eine Schluckdiagnostik mittels Bolusfärbetest und/oder FEES durchgeführt werden. Da ein physiologischer Luftstrom durch den Larynx und ein adäquater subglottischer Druck Schlüsselkomponenten eines effektiven Schluckaktes sind, sollte eine Oralisierung bei geblockter Trachealkanüle möglichst vermieden werden.
