Impact of COVID-19 on Higher Education. A case study of Uzbekistan
Authors: Cytlak Izabela 
Published: November 2021

Purpose – To identify the main challenges experienced at local Higher Educational Institutions by students while studying online during the pandemic. The research will find out the difficulties faced, and detect the areas to improve in further implementation of distance education in the country.
Motivation - Only about 11% of applicants have been accepted to High Educational Institutions in Uzbekistan for the last two years. The integration and development of distance learning will create opportunities for more young and middle-aged people who do not have enough resources to study in a traditional way. Due to the pandemic, all the educational institutions had to transfer into the online teaching system. This unexpected situation made both teachers and students of Uzbekistan face the challenges. At the same time, it created an opportunity to experience remote teaching and learning, which can become a groundwork on approval and application of distance education in Uzbekistan.
Design/Methodology/Approach – Quantitative type of research was implemented. The questionnaire was designed and the students who experienced remote learning during the pandemic at least for one semester were invited to participate.
Implications – The results of the research can be implied to develop educational policy in the Higher Education system of Uzbekistan. The outcomes of surveys were analyzed to understand how the findings can be implemented in the Higher Education of Uzbekistan. Moreover, the conclusions of the research may constitute recommendations for decision-makers in the field of higher education (rectors and dean's authorities of universities).

Published: November 2021

Abstract

The article gives a short overview of theories on didactics and distance learning used in the framework of an online course in English, given by a senior lecturer from the Netherlands (HAN) to students of the faculty of Economics of Chelyabinsk State University (CSU), to let students get experience in distance learning in an international educational environment and acquire knowledge on the topic Supply Chain Finance (SCF). The teaching material of the course was represented by six lectures recorded by J. Jansen and available online (www.principlesofsupplychainfinance.nl/scf-course/). Combination of the recorded lectures and interactive online seminars for discussion of home assignments allows students to gain a deeper understanding of the topic SCF. Finally, the course was finished with an individual online oral exam. Students and teaching staff of CSU evaluated this extra-curricular course. This pilot of distance learning will be developed into a course of a master programme at the faculty of Economics of CSU. The educational theories of Biggs, Bloom, Hattie, Garrison, Vaughan, Klabbers, Sousa and Kolb were applied to provide students with the best modern experience of distance learning.

Published: November 2021

Abstract
Entanglement is a fundamental resource that allows quantum sensors to surpass the standard quantum limit set by the quantum collapse of independent atoms. Collective cavity-QED systems have succeeded in generating large amounts of directly observed entanglement involving the internal degrees of freedom of laser-cooled atomic ensembles. Here we demonstrate cavity-QED entanglement of external degrees of freedom to realize a matter-wave interferometer of 700 atoms in which each individual atom falls freely under gravity and simultaneously traverses two paths through space while also entangled with the other atoms. We demonstrate both quantum non-demolition measurements and cavity-mediated spin interactions for generating squeezed momentum states with directly observed metrological gain 3.4^{+1.1}_{-0.9} dB and 2.5^{+0.6}_{-0.6} dB below the standard quantum limit respectively. An entangled state is for the first time successfully injected into a Mach-Zehnder light-pulse interferometer with 1.7^{+0.5}_{-0.5} dB of directly observed metrological enhancement. These results open a new path for combining particle delocalization and entanglement for inertial sensors, searches for new physics, particles, and fields, future advanced gravitational wave detectors, and accessing beyond mean-field quantum many-body physics.

Abstract
Background

Perinatal depression is broadly defined as depressive symptoms during pregnancy or within the 12 months following delivery, affecting approximately 20-25% of pregnant and postpartum women in low- and middle-income countries. The wide accessibility of mobile phones allows mobile health (mHealth) interventions to be considered a solution to identify perinatal depression and provide appropriate referrals for treatment. This study, nested in a larger SMS communication project, examined the prevalence and correlates of perinatal depression, determined the association between antenatal depression and infant morbidity/mortality, and compared SMS communication patterns between women with and without perinatal depression.
Methods

This was a prospective longitudinal cohort of pregnant women seeking antenatal services at two public sector health clinics in Kenya. SMS messages were sent to participants with educational content related to their pregnancy and infant health and two-way SMS communication occurred with a nurse. Sociodemographic and obstetric characteristics, SMS messaging behaviors, infant health status, and depressive symptoms were assessed by a standardized questionnaire administered at enrollment (30-36 weeks gestation) and follow-up (14 weeks postpartum). Generalized estimating equation (GEE) with Poisson link was used to evaluate correlates of perinatal depressive symptoms, infant outcomes, and frequency of SMS messaging.
Results

Of the 572 women with complete follow-up information, 188 (32.9%) screened positive for elevated depressive symptoms (≥10 by EPDS scale) at some time point during pregnancy or postpartum. The strongest predictors of depressive symptoms included abuse during pregnancy, fewer years of schooling, and maternal unemployment. Antenatal depressive symptoms were associated with an increased risk of infant illness or hospitalization (RR = 1.12, 95% CI: 1.11, 1.13). Women with antenatal or persistent perinatal depressive symptoms sent fewer SMS messages during the study period than their counterparts without depression.
Conclusions

Prevalence of elevated perinatal depressive symptoms was high in this cohort of Kenyan women. Our findings highlight the importance of screening perinatal women for experiences of abuse and symptoms of depression. Differences in messaging frequency between women with vs. without depressive symptoms presents a potential opportunity to provide more support for those perinatal depression.

Abstract
Understanding the physical fitness attributes in a sport-specific technical skill is a key to improve the action economy, and thus aerobic endurance performance. The present study was designed to investigate how upper limb muscle strength predicts double poling (DP) power performance in cross-country sit-skiing. A total of 19 female able-bodied college students (age 23.2±0.8 years, BMI 20.4±2.2) were subjected to a 30-s and 3-min DP performance tests using a sit-skiing ergometer. Isokinetic muscle strength by the angular velocity of 30 °/second, 60 °/second, and 120 °/second of the shoulder and elbow extensor/flexor were measured with an ISOMED2000 isokinetic system. A medium correlation was found between DP output power and isokinetic upper limb muscle strength (shoulder strength at all speed, r = 0.39-0.74, p < 0.1). Multiple regressions, which were employed to predict power production in the 30-s and 3-min tests, showed that shoulder extension strength at 60 °/second accounted for 34% of the variation in the 30-s test, and 40% of the variance in the 3-min test.

Published: November 2021

Abstract
Transitional Climate Zone (TCZ) over East Asia, characterized by semi-arid climate, is ecologically fragile environment with limited water resources, making atmospheric moisture supply being the key influential factor. This study investigates the moisture sources of summer (JJA) rainfall in the TCZ over East Asia during 1979-2010 with the Lagrangian particle dispersion model. Seven moisture source regions and associated contribution are quantified: Eurasia continent to northwest of the TCZ (EC, 18.01%), central-eastern China (CEC, 17.14%), western Pacific Ocean (WPO, 7.46%), South China Sea and Indonesia (SCSI, 3.56%), Bay of Bengal (BOB, 2.55%), Arabian Sea (AS, 2.13%) and local evaporation (TCZ, 19.96%). The moisture contribution from ocean (16.06%) is less than those from the continent (55.11%), due to the great loss en-route. In particular, the local evaporation not only contributes the most moisture among 7 selected source regions, but also has the greatest influence in summer precipitation variability in TCZ. Furthermore, westerlies precipitation and monsoon precipitation are discriminated according to the dominant system of water vapor source regions. It is found that summer monsoon contributes most of water vapor (33.2%) to summer rainfall in TCZ, while only 18.01% comes from the mid-latitude westerlies dominant area. Finally, further analysis of dry and wet years shows that summer monsoon system also takes more responsibility for a drier or wetter summer in TCZ from the perspective of moisture supply, followed by local evaporation and mid-latitude westerlies.
In-Plane Current Induced Nonlinear Magnetoelectric Effects In Single Crystal Films of Barium Hexaferrite

Published: November 2021

Abstract
This report is on the observation and analysis of nonlinear magnetoelectric effects (NLME) for in-plane currents perpendicularly to the hexagonal axis in single crystals and liquid phase epitaxy grown thin films of barium hexaferrite. Measurements involved tuning of ferromagnetic resonance (FMR) at 56-58 GHz in the multidomain and single domain states in the ferrite by applying a current. Data on the shift in the resonance frequency with input electric power was utilized to estimate the variations in the magnetic parameter that showed a linear dependence on the input electric power. The NLME tensor coefficients were determined form the estimated changes in the magnetization and uniaxial anisotropy field. The estimated NLME coefficients for in-plane currents are shown to be much higher than for currents flowing along the hexagonal axis. Although the frequency shift of FMR was higher for the single domain resonance, the multi-domain configuration is preferable for device applications since it eliminates the need for a large bias magnetic field. Thus, multidomain resonance with current in the basal plane is favorable for use in electrically tunable miniature, ferrite microwave signal processing devices requiring low operating power.
Description of the female, nymph and larva and mitochondrial genome, and redescription of the male, of Ixodes barkeri Barker, 2019 (Acari: Ixodidae) from the short-beaked echidna, Tachyglossus aculeatus, with a consideration of the most suitable subgenus for this tick

Abstract
Background
Ixodes barkeri, a tick with a distinctive ventrolateral horn-like projection on palpal segment 1, was described in 2019 from two male ticks from the Wet Tropics of Far North Queensland, Australia. However, females lie at the core of the taxonomy and subgenus classification of Ixodes, hence we sought specimens of female ticks, successfully recovering females, plus nymphs and larvae. Mitochondrial genomes are also desirable additions to the descriptions of species of ticks particularly with regard to subgenus systematics. So, we sequenced the mt genomes of I. barkeri Barker, 2019 and the possible relatives of I. barkeri that were available to us (I. australiensis Neumann, 1904, I. fecialis Warburton & Nuttall, 1909, and I. woyliei Ash et al. 2017) with a view to discovering which if any of the subgenera of Ixodes would be most suitable for I. barkeri Barker, 2019.
Results
The female, nymph, larva, and mitochondrial genome of Ixodes barkeri Barker, 2019 are described for the first time and the male of I. barkeri is redescribed in greater detail than previously. So far, I. barkeri is known only from a monotreme, the short-beaked echidna, Tachyglossus aculeatus (Shaw, 1792), from the highland-rainforests of Far North Queensland, Australia.
Conclusions
Our phylogeny from entire mitochondrial genomes indicated that I. barkeri, and indeed I. woyliei Ash et al. 2017, another tick that was described recently, are best placed in the subgenus Endopalpiger Schulze, 1935.

Published: November 2021

Abstract
Aging is a critical risk factor for developing many diseases such as skin diseases. Aging skin is caused by the decline of regenerative potential and function of tissues. Here, we aim to discover the biological function and pathways of the skin from aged people. The GSE39170 dataset was originally created by the Illumina Genome Analyzer II (Homo sapiens). The biological pathways were analyzed by the Kyoto Encyclopedia of Genes and Genomes pathway (KEGG), Gene Ontology (GO), and Reactome. KEGG and GO results showed the extracellular matrices (ECMs) were mostly affected in the aging skin. Moreover, we discovered the top ten interacting proteins including FBN1, SPARC, THBS1, DCN, COL1A2, VCAN, LOX, SERPING1, FSTL1, and FBLN5 were involved in the aging skin. Further, we predicted several inhibitors that had the ability to block the aging process by L1000fwd analysis. Thus, this study provides further insights into the mechanism of aging skin.
The role of environmental regulation, industrial upgrading and resource allocation on foreign direct investment: Evidence from 276 Chinese cities
Authors: Qiu Wei , Bian Yaojun , Zhang Jinwei , Irfan Muhammad 
Published: November 2021

Abstract
Environmental pollution is becoming more and more prevalent in China, accompanied by the excessive expansion of the country's foreign direct investment in the scale of resource-based industries. This article uses the panel data of 276 prefecture-level cities in China from 2003 to 2016 to estimate the impact of environmental regulation on foreign direct investment by employing the Spatial Durbin model. The empirical results show that: firstly, environmental regulation, and foreign direct investment have an obvious spatial correlation. Secondly, environmental regulation significantly inhibits foreign direct investment and has significant negative space spillover. Thirdly, non-eastern cities' environmental regulation has significantly greater inhibitory effects on foreign direct investment than eastern cities, and the key cities' environmental regulation has greater inhibitory effects than ordinary cities. Finally, from the perspective of industrial upgrading and resource configuration, environmental regulation has significantly promoted foreign direct investment and have significant negative space spillovers. Therefore, the reasonable use of environmental regulatory measures through industrial upgrading and resource configuration to attract clean, capital-intensive and technology-intensive enterprises and to achieve the effect of "decontamination and clean" for foreign-funded enterprises is critical.

Published: November 2021

Abstract
Background: China has the largest older population in the world. With the increasing trend of ageing, the problem of suicide among old people is increasing rapidly, especially in rural areas. The pressures and challenges faced by family members of loved ones who have committed suicide has been studied closely around the world. However, the impact of suicide on the lives of family members have not received enough attention in China. Therefore, it is very important to understand the lived experience of the family members of older people who have committed suicide. The study aims to understand the lived experiences of family members who have experienced their older family member’s suicide in a rural area based in Shaanxi Province, China.Methods: Interpretative phenomenological analysis (IPA) was used for this study. Semi-structured individual interviews with five family members of older people who have committed suicide recruited from a rural area of Shaanxi Province, China.Results: Three main themes emerged from the study: (a) Initial reactions; (b) Continual effects; (c) Social attitudes.Conclusions: With the development of China’s economic, social and cultural changes, the suicide of the older people in rural China poses a challenge to the future living quality of their family members. It shows that it is necessary to pay attention to families of older people who have committed suicide. It also shows that more support is required to improve the quality of life of families of older people who have committed suicide in rural China.

Published: November 2021

Abstract
Background: Sleep quality and fatigue have been documented as a challenge for college students, with reports indicating impacts on daytime functioning and academic achievement. The present study evaluates the effect of Pilates exercise on sleep and fatigue among female student residents in the dormitory.Methods: This quasi-experimental study involving 67 participants consisted of one experimental group (assigned Pilates exercise) and one control group. Participants in the experimental group received three one-hour sessions of Pilates exercise weekly for eight-week. Sleep quality and fatigue levels were measured by the Pittsburgh Sleep Quality Index (PSQI) and standard Multidimensional Fatigue Inventory (MFI-20), respectively. These variables were assessed at baseline, weeks four and eight of the study.Results: After four and eight weeks, findings showed an improvement in the sleep quality score (p < 0.001 and p < 0.0001, respectively). After four weeks of intervention, the mean score of the subjective sleep quality and daytime dysfunction in the Pilates group was significantly less than the control group (p < 0.001 and p < 0.002, respectively). Eight weeks of intervention had an additional effect on sleep duration and habitual sleep efficiency (p < 0.04 and p < 0.034, respectively). Also, Pilates exercise significantly reduced the total score of fatigue and its dimensions in weeks four and eight, compared to the control group (p < 0.001).Conclusions: Eight weeks of the Pilate's exercises had a significant improvement in most components of sleep quality; however, the effect of Pilates exercise on fatigue was evident from week four of the intervention.Trial registration: The study was registered on 6/2/2015 in the Iranian Registry of Clinical Trials (IRCT) with IRCT201412282324N15.

Published: November 2021

Abstract
In this paper, we have dealt with the solution of a two-stage stochastic programming problem using ADMM. We have formulated the problem into a deterministic three-block separable optimization problem, and then we applied ADMM to solve it. We have established the theoretical convergence of ADMM to the optimal solution based on the concept of lower semicontinuity and the Kurdyka-Lojasiewicz property. We have compared ADMM with Progressive Hedging in terms of performance criteria using five benchmark problems from the literature. The comparison shows that ADMM outperforms Progressive Hedging.

Abstract
Background: High-quality, representative serological surveys allow direct estimates of immunity profiles to inform vaccination strategies but can be costly and logistically challenging. Leveraging residual serum samples is one way to increase their feasibility.Methods: We subsampled 9,854 residual sera from a 2016 national HIV survey in Zambia and tested these specimens for anti-measles and anti-rubella virus IgG antibodies using indirect enzyme immunoassays. We demonstrate innovative methods for sampling residual sera and analyzing seroprevalence data, as well as the value of seroprevalence estimates to understand and control measles and rubella. Results: National measles and rubella seroprevalence for individuals younger than 50 years was 82·8% (95% CI 81·6, 83·9%) and 74·9% (95% CI 73·7%, 76·0%), respectively. Despite a successful childhood vaccination program, measles immunity gaps persisted across age groups and districts, indicating the need for additional activities to complement routine immunization. Prior to vaccine introduction, we estimated a rubella burden of 96 congenital rubella syndrome cases per 100,000 live births.Conclusion: Residual samples from large-scale surveys can reduce the cost and challenges of conducting serosurveys, and multiple pathogens can be tested. Procedures to access specimen quality, ensure ethical approvals, and link sociodemographic data can improve the timeliness and value of results.
