Sink or swim: Exploring resilience of academics at an education faculty during Covid-19

There is a proliferation of local and international research focusing on Covid-19 and its impact on teaching and learning practices in higher education. However, there is considerably less focus on the resilience of academics in higher education during the pandemic in South Africa. To consider this gap, a group of curriculum officers at an education faculty based at a university of technology in the Western Cape set out to explore how resilient academics were during Covid-19. Thirteen academics who teach in and across the Foundation, Intermediate, and Further Education and Training phases participated in a focus group interview. Data was analysed thematically using content analysis and three themes were identified: creativity through complexity; embracing challenge through resilience; and connecting with self. The implications reveal that universities as a contextual environment for promoting resilience need to engage with the social and physical ecology of staff by providing support and resources to facilitate resilience during times of crisis. The dominant nature of the hierarchical dynamics of the university's management also needs to be considered as part of a social-ecological perspective in valuing academics' wellbeing during emergencies.
An extremum property of sums of eigenvalues

We present in this note a maximum-minimum characterization of sums like a3+a7+asj where a1> . * * a. are the eigenvalues of a hermitian nXn matrix. The result contains the classic characterization of am as well as the maximum property of a1+a2+ * * * +a. given recently by Fan [4]. Though the result is valid also for a completely continuous hermitian operator in Hilbert space, we shall for the sake of simplicity assume the dimension to be finite. As an application we obtain linear inequalities relating the eigenvalues of the sum of two hermitian matrices to the eigenvalues of the summands.
Impact of Partnered Pharmacist Medication Charting (PPMC) on Medication Discrepancies and Errors: A Pragmatic Evaluation of an Emergency Department-Based Process Redesign

Medication errors are more prevalent in settings with acutely ill patients and heavy workloads, such as in an emergency department (ED). A pragmatic, controlled study compared partnered pharmacist medication charting (PPMC) (pharmacist-documented best-possible medication history [BPMH] followed by clinical discussion between a pharmacist and medical officer to co-develop a treatment plan and chart medications) with early BPMH (pharmacist-documented BPMH followed by medical officer-led traditional medication charting) and usual care (traditional medication charting approach without a pharmacist-collected BPMH in ED). Medication discrepancies were undocumented differences between medication charts and medication reconciliation. An expert panel assessed the discrepancies’ clinical significance, with ‘unintentional’ discrepancies deemed ‘errors’. Fewer patients in the PPMC group had at least one error (3.5%; 95% confidence interval [CI]: 1.1% to 5.8%) than in the early BPMH (49.4%; 95% CI: 42.5% to 56.3%) and usual care group (61.4%; 95% CI: 56.3% to 66.7%). The number of patients who need to be treated with PPMC to prevent at least one high/extreme error was 4.6 (95% CI: 3.4 to 6.9) and 4.0 (95% CI: 3.1 to 5.3) compared to the early BPMH and usual care group, respectively. PPMC within ED, incorporating interdisciplinary discussion, reduced clinically significant errors compared to early BPMH or usual care.
Dust and the transfer of stellar radiation within galaxies

We present and discuss models for the transfer of ultraviolet, visual, and near-infrared radiation within a variety of spherical geometries which are intended to approximate different types of dusty environments within galaxies. Among those objects that our models approximate are normal and starburst galaxies, active galactic nuclei and QSOs, colliding systems with a widely dispersed interstellar medium, and elliptical galaxies. Our mathematical technique is a complete spherically symmetric, three-dimensional Monte Carlo simulation which covers a wide range of dust optical depths for 10 photometric bands
Molecular identification of anaerobic fungi isolated from buffalo rumen with their growth rate, cellulase enzyme activity, and fermentation products characteristics

Abstract. Agustina S, Wiryawan KG, Suharti S, Meryandini A. 2022. Molecular identification of anaerobic fungi isolated from buffalo rumen with their growth rate, cellulase enzyme activity, and fermentation products characteristics. Biodiversitas 23: 6448-6455. Anaerobic fungi are essential microbes in the degradation process of feed fiber in the rumen with the ability to produce fibrolytic enzymes and rhizoids that can penetrate feed particles. The activity of cellulase enzymes in fungi is influenced by several factors such as the type of feed and livestock used as a source of isolate. Therefore, this research aimed to analyze the types of anaerobic fungi isolated from buffalo based on their DNA nitrogenous bases composition and also to evaluate the growth rate, cellulase enzyme activity, and fermentation product concentration of anaerobic fungi. The growth rate of fungi was examined by measuring the biomass formed, while cellulase enzyme activity was carried out using CMC, Avicel, and Filter Paper as substrates. The fungal fermentation products were analyzed using the HPLC and GC methods. The results showed that the fungi isolated from buffalo rumen were closely related to anaerobic fungi type Piromyces sp. , Caecomyces sp. , and Neocallimastix frontalis, with different growth rate, cellulase enzyme activity, and the fermentation products concentration in each type of anaerobic fungi. Therefore, it can be concluded that anaerobic fungi isolated from buffalo rumen can degrade cellulose. It was also discovered that fungi Neocallimastix frontalis had a higher growth rate, cellulase enzyme activity (CMCase, avicelase, and FPase), and fermentation products than Piromyces sp. and Caecomyces sp.
Traveling waves on vertical films: Numerical analysis using the finite element method

Finite‐amplitude waves propagating at constant speed down an inclined fluid layer are computed by finite element analysis of the Navier–Stokes equations written in a reference frame translating at the wave speed. The velocity and pressure fields, free‐surface shape and wave speed are computed simultaneously as functions of the Reynolds number Re and the wave number μ. The finite element results are compared with predictions of long‐wave, asymptotic theories and boundary‐layer approximations for the form and nonlinear transitions of finite‐amplitude waves that evolve from the flat film state. Comparisons between the finite element calculations and the long‐wave predictions for fixed μ and increasing Re agree well for small‐amplitude waves. However, for larger‐amplitude waves the long‐wave results diverge qualitatively from the finite element predictions; the long‐wave theories predict limit points in the solution families that do not exist in the finite element solutions. Comparisons between the finite ele.
Dynamic evolution of energetic outer zone electrons due to whistler mode chorus based on a realistic density model

[1] In this paper, we construct a three-dimensional realistic plasma trough electron density model (particularly a field-aligned density variation model) following the previous works. We examine the evolution of energetic electrons in the outer radiation belt at locations L = 4.5 and L = 6.0 with and without incorporation of electron density variation along magnetic field lines. Numerical calculation shows that neglect of the density variation along magnetic field lines generally results in overestimates of relativistic electrons phase space density (PSD) due to an underestimate of the plasma parameter fpe/fce along the field lines. Particularly, the overestimates of PSDs due to neglecting field-aligned density variation are found to increase with kinetic energy Ek and L increasing. At L = 4.5, maximum overestimates of PSDs over all the pitch angles are found to be by a factor of ∼1.5, 2.1, and 4.7 for energies of 1.0, 2.0, and 3.0 MeV in 2 days. At L = 6.0, maximum overestimates of PSDs over all the pitch angles are found to be by a factor of ∼1.5, 18, and 47 for energies of 1.0, 2.0, and 3.0 MeV in 2 days. This result suggests that incorporation of a field-aligned density variation model is very important to evaluate cyclotron wave-particle interaction in the outer radiation belt.
Saline Stress Impairs Lipid Storage Mobilization during Germination in Eruca sativa

Soil salinization become worse in the last decades, leading to reduced crop yields, especially in the Mediterranean basin. Eruca sativa is a common species cultivated in this area with remarkable economic importance. This study aimed at investigating the effect of salinity on this plant, focusing on (i) seedling development in terms of variations in germination and growth parameters and (ii) anatomical and ultra-structural changes in the morphology of cotyledons. For this reason, seeds were treated with different salinity levels ranging from 137 to 548 mM NaCl. Seed germination was delayed by all the concentrations tested, but only above 137 mM seedling growth was impaired. Results showed a high occurrence of lipid bodies within the mesophyll cells of cotyledons of seedlings exposed to salt concentrations above 137 mM, suggesting an impairment in lipid mobilization caused by salinity during plant development. The cotyledons of treated seedlings showed reduced intercellular spaces and ultrastructural changes in chloroplasts and peroxisomes. Moreover, salt-induced autophagic processes were present in samples grown at the highest NaCl levels. Interestingly, at 137 mM NaCl, seedlings showed the highest values of mesophyll thickness and fresh weight, implying a possible mechanism of salt adaptation during germination.
Magnetic domain formation in lithographically defined antidot Permalloy arrays

The magnetic switching of a continuous Permalloy film is artificially modified by lithographically structuring an antidot array. The antidots introduce a spatially variant shape anisotropy field that competes with the intrinsic uniaxial anisotropy of the continuous film. This results in a well-defined periodic domain structure at remanence as observed by scanning Kerr microscopy, and which could be significant for high-density data storage. A micromagnetic calculation explains the structure and indicates optimum anisotropy conditions for data storage applications.
A Lattice Boltzmann Scheme for Incompressible Multiphase Flow and Its Application in Simulation of Rayleigh-Taylor Instability

In this paper, we propose a new lattice Boltzmann scheme for simulation of multiphase flow in the nearly incompressible limit. The new scheme simulates fluid flows based on distribution functions. The interfacial dynamics, such as phase segregation and surface tension, are modeled by incorporating molecular interactions. The lattice Boltzmann equations are derived from the continuous Boltzmann equation with appropriate approximations suitable for incompressible flow. The numerical stability is improved by reducing the effect of numerical errors in calculation of molecular interactions. An index function is used to track interfaces between different phases. Simulations of the two-dimensional Rayleigh? Taylor instability yield satisfactory results. The interface thickness is maintained at 3? 4 grid spacings throughout simulations without artificial reconstruction steps.
Extending economic design of p charts to handle user specified constraints using a genetic algorithm

For certain processes, the quality of the output can be monitored using attribute inspection statistical process control. Various approaches have been used to determine optimal or near-optimal parameters for such a plan. Since most of these approaches use an unconstrained model, some solutions can result in theoretical and pragmatic problems. In this paper we used Duncan's loss function as the objective function for the development of a Genetic Algorithm (GA). In addition to formulating a GA to find a solution to the model, user constraints concerning the frequency of inspection, the number of defects allowed and the production rate are used to limit the search space for the GA. The GA is selected over other search techniques such as traditional calculus-based, enumeration, or undirected random search methods because the GA is more robust than other search techniques.
Observation of Superlubricity by Scanning Tunneling Microscopy

Experimental evidence of superlubricity, the state of vanishing friction, is obtained by examining systems of sliding atomically clean surfaces by using ultrahigh vacuum scanning tunneling microscopy. The experimental results agree with theoretical predictions: Friction is not observed in the superlubricity regime in measurements capable of resolving a friction force of $3\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}9}\mathrm{N}$, whereas friction of $8\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}8}\mathrm{N}$, which is comparable to theoretical values, is observed in the friction regime.
Mental health awareness and coping in foster carers: The impact of a counselling skills intervention

The experience of early abuse and neglect can predispose victims to mental health problems. Mental health awareness as an aspect of mental health literacy can prevent deterioration in mental health and promote post-abuse recovery. The lack of research on mental health awareness in carers means there is little understanding regarding the association between mental health awareness and their looked after children’s emotional and mental health needs. This study examined the impact of a counselling skills intervention on foster carers’ confidence in their mental health awareness and their ability to cope. This was done by enhancing communication skills. Foster carers undertook a training course in counselling skills of 30 hours duration. Data were collected before and after the course. Results indicated that foster carers believed they had a better understanding of looked after children’s emotional needs and their mental health. This study highlights the need for further training for foster carers.
The Meaning of Healing to Adult Patients with Advanced Cancer

Background: This study aimed to explore the meaning of healing from the perspective of adult patients with advanced cancer. Methods: We conducted a secondary analysis of data from a primary study which used a cognitive interview approach to assess the face and content validity of a spiritual and psychological healing measure (NIH-HEALS). This analysis focused on responses to the question, “What does the term ‘healing’ mean to you? ” Data were de-identified, transcribed verbatim, and imported in NVivo for thematic analysis in line with interpretive phenomenological methods. Results: Thirty-five adults with advanced cancer participated in the study. We identified nine major themes: acceptance, surrender, faith, hope, peace, freedom from suffering (e.g., pain, problems, or other bothersome factors), overcoming/transcending disease, positive emotions (e.g., happiness), recovery from illness or disease. One participant discussed healing as synonymous with death, and two associated it with social relations and social support. Conclusion: Themes from patients’ responses suggest subjective and varied definitions of healing which encompass physical, social, spiritual, and psychological domains of well-being, distinct from the physical cure of disease. Clinicians should adopt a holistic, person-centered approach to care, attending to bodily, psychosocial, spiritual, and emotional needs to help patients find meaning in their experiences, nourish resilience, and experience a sense of healing—as they define it.
An In Vitro Study of the Healing Potential of Black Mulberry (Morus nigra L.) Extract in a Liposomal Formulation

Natural compounds are used in modern dermal treatments to avoid side effects commonly associated with conventional treatments. The aim of our study was to develop a liposomal formulation including black mulberry extract and to highlight its potential on the healing of normal human dermal fibroblasts (NHDF) in vitro using the scratch test. Mulberry-loaded liposomes (Mn_L) were prepared using a thin-film hydration method based on cholesterol (C) and phosphatidylcholine (PC) in a 1:3 (w/w) ratio. The liposomal formulation was characterized by analyzing its size, electric surface potential, morphology, entrapment efficiency, and in vitro healing effects. Also, the black mulberry fruits (Morus nigra L.) were characterized from point of view of polyphenolic compounds and antioxidant capacity by Ferric-Reducing Antioxidant Power (FRAP) assay. HPLC-DAD-MS (ESI+) (high performance liquid chromatography-photodiode array detection-mass spectrometry (electrospray ionization)) analysis indicated the presence of phenolic compounds namely from hydroxybenzoic and hydroxycinnamic acids and flavonols. Among flavonols, quercetin-glucoside represented 50.56%, and chlorogenic acid was the predominant compound among hydroxycinnamic acids (37.06%). In vitro fibroblast wound closure was more effective with mulberry-loaded liposomes (L_Mn) than extracts of mulberries. According to our study, mulberry-loaded liposomes have been shown to be effective in wound healing and can be used as a natural treatment.
Averaging Method for One-Sided Lipschitz Differential Inclusions with Generalized Solutions

We investigate the convergence of the solution set for singularly perturbed differential inclusions using an averaging technique. The limits of the fast solutions are considered as generalized solutions (i.e., Radon probability measures) of the degenerate system. Exploiting in addition the one-sided Lipschitz condition we prove the existence of a limit of the solution set in an appropriate topology.
Investigating the regrowth surface of Si:P δ-layers toward vertically stacked three dimensional devices

We investigate the surface quality of encapsulated Si:P δ-layers for the fabrication of multilayer devices with the potential to create architectures with sub 20 nm resolution in all three spatial dimensions. We use scanning tunneling microscopy to investigate how the dopant incorporation chemistry of the first active layer strongly affects the quality of the Si encapsulation which serves as the regrowth interface for the second active layer. Low temperature Hall measurements of the encapsulated layers indicate full dopant activation for incorporation temperatures between 250–750 °C with 20% higher carrier densities than previously observed.
Is the unhappy citizen a populist citizen? Linking subjective well-being to populist and nativist attitudes

Economic grievances, globalization, and voter discontent are among the usual explanations for the surge in right-wing populism (RWP) across Western democracies. However, subjective well-being has recently been introduced as an overlooked psychological factor explaining citizens’ democratic support, immigration attitudes, and populist vote choice. Yet we know little about how general well-being, instead of specific negative sentiments, relates to populist and nativist attitudes. This study examines the well-being bases of populist and nativist attitudes in Finland where, similar to other European countries, populism and anti-immigration attitudes have increased since the early 2000’s. Using the Finnish 2019 National Election Study, we demonstrate that life dissatisfaction, and not only economic concerns, relates to populist attitudes, setting an agenda for future populism research. We suggest that past research has not fully accounted for all psychological factors in explaining support for RWP.
Experimental Studies in Speaker Verification, Using an Adaptive System

This paper describes an investigation of the capability of a two‐level adaptive linear threshold element (LTE) system to perform speaker discriminations. The study also includes an investigation of discriminating a speaker from an unknown population. The problem has been confined to the verification of an utterance as that of an expected informant. The environment of the experiments is discussed, and the experimental system is described. At the first level LTE, four different kinds of training have been developed for effective transformation and data reduction. At the second‐level LTE, different training conditions and different decision processes are investigated and evaluated. Over 90% accuracy is obtained in separating a known speaker from impostors.
Low-frequency dynamics of an electrorheological fluid in squeeze and shear mode. Part I: experiments

Electrorheological fluids (ERFs) offer a rapid control of damping using very low power requirements. Different models have been proposed to simulate the hysteresis phenomenon observed experimentally in ERF. This paper describes the steps to be taken to extract measurements of an ERF in squeeze and shear mode. A novel modular test facility was designed to perform measurements of a specific ERF in squeeze and shear mode. This device allows the measurement of the dynamic response of the fluid under various excitation conditions. Dense measurement grids of fluid force and electrode displacement at harmonic excitation are collected in dependency of the excitation frequency, the displacement amplitude and the applied electric field. The main problems to be solved during the setup and execution of the measurements are discussed. The steps to be taken during signal processing to achieve high-quality measurements as inputs for material model fitting are described in detail. Example measurements for both squeeze and shear mode are presented. The fitting of the obtained results to a material model for ERF and discussion of the resulting extended Bouc–Wen model will be the topic of an accompanying paper.
The good, the bad, the ugly: Predictors of positive and negative experiences of traditional and nontraditional graduate students

Nontraditional students pursuing an advanced degree face unique challenges as compared to full-time traditional students. Current and former masters and PhD students (N = 266) were surveyed to examine differences in their educational experiences and emotional outcomes, and determinants of their positive and negative graduate education experiences. Traditional and nontraditional students differed significantly on most of the variables. Compared to traditional students, nontraditional students reported higher positive emotional experiences. Simple linear ordinary least squares (OLS) regression models were used to examine the determinants of positive and negative experiences during graduate education. Self-fulfillment motives were the strongest predictors of positive emotional experiences, while stress and anxiety uniformly predicted negative experiences; with variability in determinants of emotional experiences between traditional and nontraditional students.
Observations of ring structure in a sunspot associated source at 6 centimeter wavelength

The detection of a new kind of sunspot-associated source in which the emission comes predominantly from a ring structure with size between that of the umbra and the penumbra is reported. The absence of emission from the center of the spot is interpreted in terms of the orientation of the magnetic field and the presence of low temperature material above the umbra.
