Re-positioning SoTL toward the T-shaped Community
Authors: Eady Michelle , Abrahamson Earle , Green Corinne , Arcellana-Panlilio Mayi , Hatfield Lisa , Namaste Nina
Published: March 2021

Amongst a range of changes that have taken place within tertiary education, perhaps the most revolutionary has been a shift to student-centred approaches focused on life-long learning. Accompanying this approach to holistic higher education (HE) has been a growing interest in, and understanding of, the Scholarship of Teaching and Learning (SoTL). SoTL has, at its core, a deep concern with student learning and is therefore well-aligned with higher education’s renewed focus on its students. In this conceptual paper, we examine the impact of the T-shaped person which many tertiary institutions are operationalizing to inform and connect the development of students’ deep disciplinary knowledge with non-academic and employment readiness skills (such as communication, problem-solving, teamwork, and critical thinking). Importantly, we argue for a re-positioning of SoTL to complement and support this model, with SoTL as both the fulcrum and the fluid, multiple threads of discourse that are intricately entwined around the structure of the T-shaped model. We encourage our colleagues to strive to be T-shaped practitioners and we cast a vision of a T-shaped community. Here, all stakeholders within HE connect both their academic knowledge and holistic skills in collaborative ways to produce learners who flourish in modern society. The SoTL community plays a pivotal role in achieving this vision and is well-positioned to expand the current notion of SoTL toward a more holistic, interconnected, central role in HE.
Telling Students it’s O.K. to Fail, but Showing Them it Isn’t: Dissonant Paradigms of Failure in Higher Education
Authors: Feigenbaum Paul
Published: March 2021

Educators increasingly extol failure as a necessary component of learning and growth. However, students frequently experience failure as a source of fear and anxiety that impedes risk-taking and experimentation. This essay examines the dissonance between these generative and stigmatized paradigms of failure, and it offers ideas for better negotiating this dissonance. After conceptualizing the two paradigms, I examine various factors that reinforce failure’s stigmatization. I emphasize precarious meritocracy, a neoliberal ethos driven by hypercompetitive individualism that makes success a zero-sum game, and that causes especially significant harms on students who are already socially stigmatized. Efforts to ameliorate paradigm dissonance tend to focus on changing student dispositions or lowering the stakes of failure. I instead propose wise interventions that include analyzing the systemic roots of stigmatized failure and making failure a more communal experience. I then briefly address the systemic transformations necessary to cultivate generative failure more broadly.

Industrial and technological advancements have been able to improve the welfare of humanity, but present the consequences of environmental pollution which ultimately also affects human life. The well water used by residents as a necessity of life can be polluted due to gold mining because the gold mining is located not far from the residential area. The purpose of this study is to determine the levels of mercury in the liquid medium before and after the adsorption process, determine the ability of coal fly ash as an adsorbent in absorbing mercury in the liquid medium and determine the optimum contact times in mass variations of coal fly ash.Activation of coal fly ash was done by calcination for 2 hours, followed by measurement of initial concentration for liquid medium, the adsorption process is carried out with a coal fly ash mass variation of 4, 6, 8 and 10 g, and variations of adsorption time that is 10, 20, 30, 40 and 50 minutes. From the results of the study, obtained levels of mercury in the liquid medium before the adsorption process was carried out at 0.3263 ppm and after the adsorption process ranged from 0.2053 to 0.3023 ppm. Thus, coal fly ash has a low absorption ability to mercury in liquid medium and the best contact time where adsorption occurs for a mass of 6 g is at 10 minutes which is equal to 0.1210 ppm.

Poly(2-methoxyethyl acrylate) (PMEA) and poly(ethylene oxide) (PEO) have protein-antifouling properties and blood compatibility. ABA triblock copolymers (PMEAn-PEO11340-PMEAn (MEOMn)) were prepared using single-electron transfer-living radical polymerization (SET-LRP) using a bi-functional PEO macroinitiator. Two types of MEOMn composed of PMEA blocks with a degree of polymerization (DP = n) of 85 and 777 were prepared using the same PEO macroinitiator. MEOMn formed flower micelles with a hydrophobic PMEA (A) core and hydrophilic PEO (B) loop shells in diluted water with a similar appearance to petals. The hydrodynamic radii of MEOM85 and MEOM777 were 151 and 108 nm, respectively. The PMEA block with a large DP formed a tightly packed core. The aggregation number (Nagg) of the PMEA block in a single flower micelle for MEOM85 and MEOM777 was 156 and 164, respectively, which were estimated using a light scat-tering technique. The critical micelle concentrations (CMCs) for MEOM85 and MEOM777 were 0.01 and 0.002 g/L, respectively, as determined by the light scattering intensity and fluorescence probe techniques. The size, Nagg, and CMC for MEOM85 and MEOM777 were almost the same inde-pendent of hydrophobic DP of the PMEA block.

Published: March 2021

Background: The Short Physical Performance Battery (SPPB) is an established test of physical performance. We provide reference values for SPPB and determine SPPB performance and cut-offs in assessing sarcopenia for Asian community-dwelling older adults.Methods: 538 (57.8% women) community-dwelling adults aged 21–90 years were recruited. SPPB and its subtest scores and timings (8ft gait speed (GS), five-times repeated chair sit-to-stand (STS) and balance) were determined. Appendicular lean mass divided by height-squared, muscle strength (handgrip) and physical performance (6m GS, STS and SPPB) were assessed to define sarcopenia for various Asian criteria. Area under the ROC curve (AUC) was used to assess performance of SPPB and subtests in discriminating sarcopenia in adults aged ≥60 years. Optimal SPPB and GS subtest cut-offs for each sarcopenia criterion were determined by maximizing sensitivity and specificity. Results: The mean SPPB score was 11.6(SD 1.1) in men and 11.5(SD1.2) in women. Majority of participants(≥50%) aged 21–80 years achieved the maximum SPPB score. SPPB total and subtest scores generally decreased with age (all p<0.001), but did not differ between sex. Among older adults (≥60 years), SPPB and GS subtest had varied performance in assessing sarcopenia (AUC 0.54–0.64 and 0.51–0.72, respectively), and moderate-to-excellent performance in assessing severe sarcopenia (AUC 0.69–0.98 and 0.75–0.95, respectively), depending on sarcopenia definitions. The optimal cut-offs for discriminating sarcopenia in both sexes were SPPB ≤11points and GS subtest ≤1.0m/s. The most common optimal cut-offs for discriminating severe sarcopenia according to various definitions were SPPB ≤11points in both sexes, and GS ≤0.9m/s in men and ≤1.0m/s in women.Conclusions: Population-specific normative SPPB values are important for use in diagnostic criteria and to interpret results of studies evaluating and establishing appropriate treatment goals. Performance on the SPPB should be reported in terms of the total sum score and registered time to complete the repeated-chair STS and 8-ft walk tests. The performance of GS subtest was comparable to SPPB and could be a useful, simple and accessible screening tool for discriminating severe sarcopenia in community-dwelling older adults.
Urban heat island estimation from improved selection of urban and rural stations by DTW algorithm

Published: March 2021

Typical urban and rural temperature records are essential for the estimation and comparison of urban heat island effects in different regions, and the key issues are how to identify the typical urban and rural stations. This study tried to analyze the similarity of air temperature sequences by using dynamic time warping algorithm (DTW) to improve the selection of typical stations. We examined the similarity of temperature sequences of 20 stations in Beijing and validated by remote sensing, and the results indicated that DTW algorithm could identify the difference of temperature sequence, and clearly divide them into different groups according to their probability distribution information. The analysis for station pairs with high similarity could provide appropriate classification for typical urban stations (FT, SY, HD, TZ, CY, CP, MTG, BJ, SJS, DX, FS) and typical rural stations (ZT, SDZ, XYL) in Beijing. We also found that some traditional rural stations can’t represent temperature variation in rural surface because of their surrounding environments highly modified by urbanization process in last decades, and they may underestimate the urban climate effect by 1.24℃. DTW algorithm is simple in analysis and application for temperature sequences, and has good potentials in improving urban heat island estimation in regional or global scale by selecting more appropriate temperature records.
G-Estimation of Causal Pathways in Vocational Rehabilitation For Adults With Psychotic Disorders – A Secondary Analysis of A Randomized Trial
Authors: Klungsøyr Ole , Lystad June Ullevoldsæter , Bull Helen , Evensen Stig , Ueland Torill , Falkum Erik
Published: March 2021

Background: Vocational rehabilitation (VR) has increasingly become an important intervention targeting poor occupational functioning in schizophrenia. The Norwegian Job Management Program (JUMP), sought to enhance occupational outcomes by augmenting VR with either cognitive behavioral therapy (CBT) techniques aiming to improve psychotic symptoms or cognitive remediation (CR) aiming to improve cognition. CBT is standard treatment in schizophrenia, but recent meta-analyses question the effect of CBT on negative psychotic symptoms. It is of interest to study the causal role of psychotic symptoms and cognitive functioning on occupational functioning. Methods: Data from the JUMP VR – program, was reanalyzed with a causal inference method to assess the causal effects of reduced symptoms / improved neurocognitive functioning on occupational functioning measured by number of working hours per week. Participants (N=131) had been randomized to either VR + CBT (N=68) or VR + CR (N=63). Large improvements in number of working hours were demonstrated in both intervention groups (nonsignificant group difference). G-estimation was used to assess the strength and nature of the causal effects, adjusted for time-varying confounding and selection – bias from loss to follow-up. Results: Significant causal effects of reduction in each of four dimensions of symptoms and improved neurocognition respectively, on number of working hours were found (separate models). The effect of negative symptoms was the strongest and increased in magnitude during the whole observation period, while the effect of the other symptoms and neurocognition was constant. Adjusted for confounding (including potential feedback), the causal effect of a hypothetical change in negative symptoms equal to the average improvement in the CBT group corresponded to an increase in working hours of 3.2 hours per week (95% CI: 1.11, 5.35).Conclusion: High performance of g-estimation in a small psychiatric data set with few repeated measures and time-varying confounding and effects, was demonstrated. Augmented vocational rehabilitation showed causal effects of intervention targets with the strongest and increasing effect from negative symptoms on number of working hours.Combination of therapy and activation (indirect and direct approach) might explain improvement in both cognition and negative symptoms, and shed some light on effective ingredients for improved treatment of negative symptoms.

Authors: Kapetanovic Ante Lojic , Susnjara Anna , Poljak Dragan
Published: March 2021

This paper examines the effect of electromagnetic induction on the electrophysiology of a single cortex neuronthrough two different modes associated with the nature of the external neuronal stimulus. By using the recently extended induction-based variant of the well-known and biologically plausible Hodgkin-Huxley neuron model, bifurcation analysis is performed. Electromagnetic induction caused by magnetic flux is captured using a polynomial approximation of a memristor embedded into the neuron model. In order to determine true influence of the variability of ion channels conductivity, the stochastic sensitivity analysis is performed post hoc. Additionally, numerical simulations are enriched with uncertainty quantification, observing values of ion channels conductivity as random variables. The aim of the study is to computationally determine the sensitivity of the action potential dynamics with respect to the changes in conductivity of each ion channel so that the future experimental procedures, most often medical treatments, may be adapted to different individuals in various environmental conditions.

The influence of sulfur precursors on the structure, optical and electrical properties of prepared CTS material is investigated. The sulfur precursor sources have showed a noticeable effect on crystallite size, secondary phases, and resulted CTS nanoparticles structure. Among the four sulfur precursor sources used in this study, thiourea is the only sulfur source that produces CTS with a cubic structure and without the need for thermal treatment. Whereas after sulfurization at 580 ºC, all the four samples attained CTS nanoparticles with diverse properties. Changing the sulfur precursors have clear effects on crystallite size and optical bandgap prepared samples as they ranged from 11.21 to 21.23 nm and from 1.4 to 1.7 eV, respectively. Additionally, Hall effect measurement revealed that all CTS samples are p-type semiconductors with bulk carrier concentrations in 1018 order, which is suitable for various optoelectronic applications such as photovoltaics and photodetectors.

Tropical cyclones (TCs) are one of the most destructive natural hazards that pose a serious threat to society around the globe, particularly to those in the coastal regions. In this work, we study the temporal evolution of the regional weather conditions in relation to the occurrence of TCs using climate networks. Climate networks encode the interactions among climate variables at different locations on the Earth's surface, and in particular, time-evolving climate networks have been successfully applied to study different climate phenomena at comparably long time scales, such as the El Ni~no Southern Oscillation, different monsoon systems, or the climatic impacts of volcanic eruptions. Here, we develop and apply a complex network approach suitable for the investigation of the relatively short-lived TCs. We show that our proposed methodology has the potential to identify TCs and their tracks from mean sea level pressure (MSLP) data. We use the ERA5 reanalysis MSLP data to construct successive networks 20 of overlapping, short-length time windows for the regions under consideration, where we focus on the north Indian Ocean and the tropical north Atlantic Ocean. We compare the spatial features of various topological properties of the network, and the spatial scales involved, in the absence and presence of a cyclone. We find that network measures such as degree and clustering exhibit significant signatures of TCs and have striking similarities with their tracks. The study of network topology over time scales relevant to TCs allows us to obtain useful insights into the individual local signature of changes in the flow structure of the regional climate system.

Background:Coronavirus disease 2019 (COVID-19) is a highly infectious respiratory tract disease. The most common clinical manifestation of severe COVID-19 is acute respiratory failure. Respiratory rehabilitation can be a crucial part of treatment but data lack for patients with COVID-19. This study investigates the effects of short-term respiratory rehabilitation (i.e., breathing exercises) on respiratory recovery among hospitalised patients with COVID-19. Methods: This quasi-experimental, pre-post-test study recruited 110 patients hospitalised with COVID-19. All patented received standardised care, and 65 patients also received the intervention (i.e., breathing exercises). Data on peripheral oxygen saturation (SpO2), respiratory rate (breaths/minute) and heart rate (beats/minute) and oxygen therapy requirement (litre/min) were collected at baseline and 4-5 days after the baseline assessment. Analysis of variance on repeated measures was applied to compare the outcomes of two-time points. Results: The mean (±Standard deviation, SD) age of the intervention group was 49.5 (±10.4) years and 73.8% were men. The mean (±SD) age of the control group was 49.3 (±7.9) years and 62.2% were men. After 4-5 days of respiratory rehabilitation SpO2 (96.7% ±2.1 vs 90.4% ±1.5), P<0.01), respiratory rate (20.5 ±2.4 vs 23.0 ±2.2) breaths/minute, P<0.01), heart rate (80.5 ±9.2 vs 91.2 ±8.6) beats/minute, P<0.01), and oxygen therapy requirement (0.4 ±0.98 vs 1.4 ±2.0) litre/min, P<0.01) improved in the intervention group compared to the control group. The mean days of hospitalisation for the intervention group and the control group were 7.1 days vs. 14.6 days, respectively. Conclusions:Our results indicate that breathing exercise, even for a short period, is effective in improving certain respiratory parameters in patients with COVID-19. As a non-invasive and cost-effective respiratory rehabilitation intervention, breathing exercise can be a useful tool for a health care system overwhelmed by the COVID-19 pandemic. These results should be considered preliminary until they are replicated in larger samples in different settings.
About the Chinese Book “The Book of Poetry”

“The Shi Jing’’(‘‘The Book of Poetry”） is one of the first poems in the world, including Chinese poems, from the 11th century BC to the 6th century BC. During this period, about 3 000 verses appeared, of which 305 poems were selected by Confucius. Poetic texts in “The Shi Jing’are divided into three categories: regional songs, odes, hymns. The composition of the poems uses such techniques as Fu, Bi and Xing. These poems constitute the creative source (source) of Chinese poetry. “Fu”，“Bi” and “Xing” are important artistic features of “The Shi Jing”. “Fu”” - direct narration, parallelism. “Bi” is a metaphor, comparison. “Sin” means “stimulation”， it first speaks about others, then about what the poet wants to express. Fu and Bi are the most basic techniques of expression, and Xing is a relatively unique technique in “The Shi Jing”， even in Chinese poetry in general. “The Shi Jing” is an excellent starting point for Chinese literature, which has already reached a very high artistic level from the very beginning. "The Shi Jing” affects almost all aspects of the early social life of ancient China, such as sacrifice, banquet, labor, war, love, marriage, corvee, animals, plants, oppression and resistance, manners and customs, even astronomical phenomena, etc. It became historical value for the study of that society. The overwhelming majority of the poems in “The Shi Jing”reflect the reality, everyday life and everyday experience. There is almost no illusory and supernatural mythical world in it. As the first collection of poetry in China, “The Shi Jing” laid the foundation for the lyrical and realistic tradition of Chinese literature. “The Shi Jing” also has a huge impact on the genre structure and linguistic art of Chinese literature, etc., which is a role model for writers of later generations. “The Shi Jing”has already been translated into the languages of the countries of the world. “The Shi Jing”has been influencing Chinese poetics; it has become the source of the classical realistic tradition and literature in China. Lively description is essential for historical, anthropological and sociological research. We expect that as the cultural ties between China and Russia deepen, as well as the popularization and spread of Chinese-Russian translations, more and more Russian people will read “The Shi Jing”， study “The Shi Jing”， the Russian translation of “The Shi Jing” will improve and play its role as the original classic of Chinese literature. “The Shi Jing”is a book that cannot be read or translated forever.

Antibiotics have received great attention because of their abuse and potential hazards to the human health and environment. In the current work, peroxymonosulfate (PMS) was added to a cerium oxide (CeO2)/ultrasonic (US) system for tetracycline (TC) degradation. CeO2 nanoparticles (NPs) were synthesized by a simple and cost-effective method using Stevia rebaudiana leaf extract and cerium nitrate as precursors. The as-synthesized CeO2 NPs were characterized by X-ray diffraction, field emission scanning electron microscopy, and Fourier-transform infrared spectroscopy analysis. The effects of catalyst dosage, PMS concentration, US power, initial antibiotic concentration, and pH on TC removal were investigated. The results confirmed the formation of CeO2 NPs with a fluorite structure, spherical shape, and average particle size of 29 nm. The removal efficiency of TC was 92.6% in the optimum oxidation conditions ([TC] = 15 mg/L, [PMS] = 50 mM, [CeO2] = 0.6 g/L, pH = 6, and US = 70 W) and followed the zero-order kinetics. Experiment scavenger demonstrated both sulfate and hydroxyl radicals (SO4•−, •OH) were responsible for degrading antibiotics. Biogenic CeO2 NPs and ultrasound waves-activated PMS is a promising technology for water pollution caused by contaminants such as pharmaceuticals.

Low back pain is the most common symptom found in the primary health care and is the number one cause of disability throughout worldwide. It is estimated that around 60 – 80% the world population will experience back pain during their lifespan. There are three different source of pain in the spine: axial-lumbosacral, radicular and reffered pain. All of these source brings different clinical presentations. Low back pain could be classified as acute, subacute and chronic low back pain. The pain could be nociceptive or neuropathic, the most common symptoms reported are “pressure pain” and “pain attack”. The physician should be aware of “red flags” symptoms that lead into more serious condition beside back pain and, therefore the patient has to be investigated to further examination whenever these symptoms present. The management of low back pain consist of severe modalities, both therapeutic and rehabilitative procedure. Oftentimes, the management needed multidisciplinary approach. It is important to general practitioners to identify and treat low back pain appropriately to reduce the burden of the disease and to prevent the disabilties caused by this condition.
