Published: June 2022

This study sought to determine the skills of the birth attendants in neonatal resuscitation at Nakuru Level five Hospital. Prospective study was used to determine the immediate outcomes of neonatal resuscitation where sixty resuscitated new-borns were recruited into the study and followed up for a period of one month. A descriptive cross-sectional study was used to assess the knowledge and skills of skilled birth attendants where thirty six skilled birth attendants were included in the study with various educational level Certificate, Diploma and Bachelors. Self-administered questionnaires were used to assess knowledge while simulated resuscitation using mannequins was used to assess the skills.  Multiple linear regressions were used to compare the mean differences. The findings showed that there were a higher number of resuscitated new-borns among prim gravidas, mothers aged below 20 years and referrals cases. Furthermore male new-borns were found to be twice more likely to be resuscitated than female new-borns. There is need to put emphasis teaching of neonatal resuscitation in all pre-service medical institutions to help reduce the noted discrepancies skills. Efforts should be made by the stake holders; both national and county governments to provide refresher courses yearly to all the staff  since it has been demonstrated as having impact on the skills of neonatal resuscitation.
Effectiveness of Performance Appraisal Among Public School Teachers: A Narrative Inquiry
Authors: Subedi Dhanapati , Ghaju Bikash
Published: June 2022

This study explores the effectiveness of performance appraisal among public school teachers of Kathmandu valley. Two head teachers and two permanent teachers of two public schools in Kathmandu valley were purposively interviewed to elicit in-depth information. Narrative inquiry was adopted to explore the participants' lived experiences about dimensions of performance appraisal. Herzberg’s two-factor theory was adopted to overview the effectiveness of teachers’ appraisal. This research revealed that performance appraisal was an annual process in public schools. However, the intention did not meet the expectations. Rather than being a regular process, the annual process was simply like a formality where the teachers were expected to submit one of their best works and get eligible for promotion rather than being provided with a detailed evaluative review of their continuous practice. Rather than involving the feedback from different members of the organisation, only one person got involved in the process, who usually got nervous about it for being blamed for being biased and, thus, provided positive grades only by hesitating to be critical. Teachers took this process as a burden and were not usually involved in it after securing their permanent position in the schools. Meanwhile, the temporary teachers were never made a part of the process. This study concludes that performance appraisal is seen as no more than providing secret feedback without a proper rubric as a mere formality.
Towards participatory worldview in education and research: A philosophical inquiry on the question- Why participatory?
Authors: Wagle Shree Krishna
Published: June 2022

This article portrays the author’s philosophical inquiry on the prospects of a participatory worldview in education and research. To this, the author begins his inquiry process, reflecting upon his own personal/ professional shift from rational (analytical) academician to the transformative educational practitioner. The reflection further depicts his continuous growth as a participatory researcher. Reflecting upon his personal/ professional journey, which is parallel to the spiral of human civilization from participatory to (post)positivist to constructivist to transformative to participatory again, the author makes philosophical observation at genealogical progression (spiral) of participatory worldview both in the East and the West. Also, the author observes current developments in the field of quantum science and renders how such developments have paved manifold ways for a participatory worldview in Social Science, particularly in education and research.

Bayesian estimation for parameters and the reliability of products for which the performance degradation process modeled by wiener process are obtained based on linex loss function. Using both non-informative and conjugate prior distribution, several Bayesian estimates under squared error and linex loss functions are computed. Finally, these Bayesian estimates are compared through the mean squared error (MSE) based on Monte Carlo simulation study. According to these comparisons, it is shown that Bayesian estimators with linex loss function are more flexible.

Abstract. An optimal estimation-based algorithm is developed to retrieve the number density of excited oxygen (O2) molecules that generate airglow emissions near 0.76 µm (b1Σg+ or A band) and 1.27 µm (a1Δg or 1Δ band) in the upper atmosphere. Both oxygen bands are important for the remote sensing of greenhouse gases. The algorithm is applied to the limb spectra observed by the SCanning Imaging Absorption spectroMeter for Atmospheric CHartographY (SCIAMACHY) instrument in both the nominal (tangent heights below ∼ 90 km) and mesosphere–lower thermosphere (MLT) modes (tangent heights spanning 50–150 km). The number densities of emitting O2 in the a1Δg band are retrieved in an altitude range of 25–100 km near-daily in 2010, providing a climatology of O2 a1Δg-band airglow emission. This climatology will help disentangle the airglow from backscattered light in nadir remote sensing of the a1Δg band. The global monthly distributions of the vertical column density of emitting O2 in a1Δg state show mainly latitudinal dependence without other discernible geographical patterns. Temperature profiles are retrieved simultaneously from the spectral shapes of the a1Δg-band airglow emission in the nominal limb mode (valid altitude range of 40–100 km) and from both a1Δg- and b1Σg+-band airglow emissions in the MLT mode (valid range of 60–105 km). The temperature retrievals from both airglow bands are consistent internally and in agreement with independent observations from the Atmospheric Chemistry Experiment Fourier transform spectrometer (ACE-FTS) and the Michelson Interferometer for Passive Atmospheric Sounding (MIPAS), with the absolute mean bias near or below 5 K and root mean squared error (RMSE) near or below 10 K. The retrieved emitting O2 number density and temperature provide a unique dataset for the remote sensing of greenhouse gases and constraining the chemical and physical processes in the upper atmosphere.
Estimating the impact of the 1991 Pinatubo eruption on mesospheric temperature by analyzing HALOE (UARS) temperature data
Authors: Wallis Sandra , Hoffmann Christoph Gregor , von Savigny Christian
Published: June 2022

Abstract. The Mt. Pinatubo eruption in 1991 had a severe impact on the Earth system, with a well-documented warming of the tropical lower stratosphere and a general cooling of the surface. This study focuses on the impact of this event on the mesosphere by analyzing solar occultation temperature data from the Halogen Occultation Experiment (HALOE) instrument on the Upper Atmosphere Research Satellite (UARS). Previous analyses of lidar temperature data found positive temperature anomalies of up to 12.9 K in the upper mesosphere that peaked in 1993 and were attributed to the Pinatubo eruption. Fitting the HALOE data according to a previously published method indicates a maximum warming of the mesosphere region of 4.1 ± 1.4 K and does not confirm significantly higher values reported for that lidar time series. An alternative fit is proposed that assumes a more rapid response of the mesosphere to the volcanic event and approximates the signature of the Pinatubo with an exponential decay function having an e-folding time of 6 months. It suggests a maximum warming of 5.4 ± 3.0 K, if the mesospheric perturbation is assumed to reach its peak 4 months after the eruption. We conclude that the HALOE time series probably captures the decay of a Pinatubo-induced mesospheric warming at the beginning of its measurement period.
Single-species dinoflagellate cyst carbon isotope fractionation in from coretop sediments: environmental controls, CO2-dependency and proxy potential

Published: June 2022

Abstract. Sedimentary bulk organic matter and various molecular organic components exhibit strong CO2-dependent carbon isotope fractionation relative to dissolved inorganic carbon sources. This fractionation (εp) has been employed as proxy for paleo-pCO2. Yet, culture experiments indicate this CO2-dependent εp is highly specific at genus and even species level, potentially hampering the use of bulk organic matter and non-species specific organic compounds. In recent years, significant progress has been made towards a CO2 proxy using controlled growth experiments with dinoflagellate species, also showing highly species-specific εp values. These values were, however, based on motile specimens and it remains unknown whether these relations also hold for the organic-walled resting cysts (dinocysts) produced by these dinoflagellate species in their natural environment. We here analyze dinocysts isolated from core-tops from the Atlantic Ocean and Mediterranean Sea, representing several species (Spiniferites elongatus, S. (cf.) ramosus, S. mirabilis, Operculodinium centrocarpum sensu Wall & Dale (1966) (hereafter referred to as O. centrocarpum) and Impagidinium aculeatum) using Laser ablation – nano Combustion – Gas Chromatography – Isotope Ratio Mass Spectrometry (LA/nC/GC-IRMS). We find that the dinocysts produced in the natural environment are all significantly more 13C-depleted compared to the cultured motile dinoflagellate cells, implying higher overall εp values and, moreover, exhibit large isotope variability. Where several species could be analysed from a single location, we often record significant differences in isotopic variance and offsets in mean δ13C values between species, highlighting the importance of single-species carbon isotope analyses. The most geographically expanded dataset, based on O. centrocarpum, shows that εp correlates significantly with various environmental parameters. Importantly, O. centrocarpum shows a CO2-dependent εp above ~240 μatm pCO2. Similar to other marine autotrophs, relative insensitivity at low pCO2 is in line with a carbon concentrating mechanism being active at low pCO2, although we here cannot fully exclude that we partly underestimated εp sensitivity at low pCO2 values due to the relatively sparse sampling in that range. Finally, we use the relation between εp and pCO2 in O. centrocarpum to propose a first pCO2 proxy based on a single dinocyst species.
Seasonal variation of eddy activity and associated heat/salt transport in the Bay of Bengal based on satellite, Argo and 3D reprocessed data
Authors: Cui Wei , Zhang Jie , Yang Jungang
Published: June 2022

Abstract. Based on satellite altimetry data spanning over 26 years in combination with Argo profile data or three‐dimensional (3D) reprocessed thermohaline fields, the eddy synthesis method was used to construct vertical temperature and salinity structures of eddies in the Bay of Bengal, and the seasonal thermohaline properties of eddies and the heat and salt transport by eddies were analyzed. Analysis revealed that mesoscale eddy activity in the Bay of Bengal has evident seasonal variation, which has notable impact on the circulation system within the entire bay. Temperature anomalies caused by eddies are usually between ±1 °C and ±3 °C, positive for anticycloic eddies (AEs) and negative for cyclonic eddies (CEs), and the magnitude varies seasonally. Salinity anomalies caused by eddies are small and disturbance signals in the southern bay due to the small vertical gradient of salinity there; salinity anomalies in the northern bay are generally between ±0.2 psu and ±0.3 psu, negative for AEs and positive for CEs. Owing to obvious seasonal changes of both the eddy activity and the vertical thermohaline structure in the Bay of Bengal, the eddy-induced heat and salt transport in different seasons also changes substantially. Generally, high heat and salt transport is concentrated in eddy-rich regions, e.g., the western, northwestern and eastern parts of the bay, the seas to the east of Sri Lanka, and the region to the southeast outside of the bay. The southern part of the bay shows weak freshwater transport owing to the inconsistent salinity signal within eddies. The seasonal ZHT of CEs and AEs in the whole bay is in the order of 10×1012 W, with higher values in autumn and winter and smaller values in spring and summer. The seasonal ZWT of CEs is generally larger than that of AEs, thus the ZWT of all eddies is eastward with high values (> 5×103 m3·s-1) in summer and autumn. By contrast, the seasonal MHT and MWT in the whole bay is relatively small, mostly below 1×1012 W and 2×103 m3·s-1, respectively. This work provides data that could support further research on the heat and salt balance of the entire Bay of Bengal.
Impacts of the proposal of the CNG2020 strategy on aircraft emissions of China-Foreign routes

Published: June 2022

Abstract. Aviation emission accounting is the key to establishing market measures to control aviation pollutant emissions. Based on the Fuel Percentage Method (FPM), this paper applies the Improved BFFM2-FOA-FPM method to calculate the emissions of six pollutants (CO2, CO, HC, NOx, SO2, and PM2.5) between Chinese and foreign cities from 2014 to 2019, including Landing and Take-off (LTO) emissions and Climb/Cruise/Descent (CCD) emissions. The error rate between the calculated results and the official data is about 2.75 %. The results show that the emissions of six pollutants have changed before and after the proposal of the "Carbon Neutral Growth 2020 " strategy (CNG2020 strategy). Although the total amount has increased, the average emission per ton-kilometre of CO2, CO, HC, NOx, SO2, and PM2.5 had decreased by 17.77 %, 17.26 %, 25.15 %, 14.32 %, 17.77 % and 16.35 %, respectively. The dataset is available from https://doi.org/10.6084/m9.figshare.20071751.v1 (Cui, 2022).
On the Value of Satellite Remote Sensing to Reduce Uncertainties of Regional Simulations of the Colorado River
Authors: Xiao Mu , Mascaro Giuseppe , Wang Zhaocheng , Whitney Kristen M. , Vivoni Enrique R.
Published: June 2022

Abstract. As the major water resource in the southwestern United States, the Colorado River is experiencing decreases in naturalized streamflow and is predicted to face severe challenges under future climate scenarios. To better quantify these hydroclimatic changes, it is crucial that the scientific community establishes a reasonably accurate understanding of the spatial patterns associated with the basin hydrologic response. In this study, we employed remotely sensed Land Surface Temperature (LST) and Snow Cover Fraction (SCF) data from the Moderate Resolution Imaging Spectroradiometer (MODIS) to assess a regional hydrological model applied over the Colorado River Basin between 2003 and 2018. Based on the comparison between simulated and observed LST and SCF spatiotemporal patterns, a stepwise strategy was implemented to enhance the model performance. Specifically, we corrected the forcing temperature data, updated the time-varying vegetation parameters, and upgraded the snow-related process physics. Simulated nighttime LST errors were mainly controlled by the forcing temperature, while updated vegetation parameters reduced errors in daytime LST. Snow-related changes produced a good spatial representation of SCF that was consistent with MODIS but degraded the overall streamflow performance. This effort highlights the value of Earth observing satellites and provides a roadmap for building confidence in the spatiotemporal simulations from regional models for assessing the sensitivity of the Colorado River to climate change.
Timing landslide and flash flood events from SAR satellite: a new method illustrated in African cloud-covered tropical environments

Published: June 2022

Abstract. Landslides and flash floods are geomorphic hazards (GH) that often co-occur and interact. They generally occur very quickly, leading to catastrophic socioeconomic impacts. Understanding the temporal patterns of occurrence of GH events is essential for hazard assessment, early warning and disaster risk reduction strategies. However, temporal information is often poorly constrained, especially in frequently cloud-covered tropical regions, where optical-based satellite data is insufficient. Here we present a new method to accurately estimate GH event timing which requires no prior knowledge of the GH event timing, using Synthetic Aperture Radar (SAR) remote sensing. SAR can penetrate through clouds and therefore provides an ideal tool for constraining GH event timing. We use the open-access Copernicus Sentinel-1 (S1) SAR satellite that provides global coverage, high spatial resolution (~10–15 m) and a high repeat time (6–12 days) from 2016 to 2020. We investigate the amplitude, detrended amplitude, spatial amplitude correlation, coherence and detrended coherence time series in their suitability to constrain GH event timing. We apply the method on four recent large GH events located in Uganda, Rwanda, Burundi and DRC containing a total of about 2500 manually mapped landslides and flash flood features located in several contrasting landscape types. The GH event timing estimation accuracies vary among the GH events and the data products. Coherence and detrended coherence estimated timing accuracies range from a 1 day to a 47 day difference. The spatial amplitude correlation estimated timing accuracy ranges from a 1 day to an 85 day difference. The amplitude and detrended amplitude estimated timing accuracies range from a 13 to a 1000 day difference. The amplitude time series reflects the influence of seasonal dynamics, which causes the timing estimations to be further away from the actual GH event occurrence compared to the other data products. Timing estimations are generally closer to the actual GH event occurrence for GH events within homogenous densely vegetated landscape, and further for GH events within complex cultivated heterogenous landscapes. We believe that the complexity of the different contrasting landscapes we study is an added value for the transferability of the method and together with the open access and global coverage of S1 data it has the potential to be widely applicable.

THE EXPANSION AND INTERNATIONALIZATION OF MANDATORY DISCLOSURE RULES
Authors: Noked Noam , Marcone Zachary , Tsang Alison
Published: June 2022

The Panama Papers, the Paradise Papers, and most recently the Pandora Papers have exposed the role of tax advisors, lawyers, financial institutions, and other intermediaries in enabling cross-border tax avoidance and evasion. In response, mandatory disclosure rules (MDRs), which require that intermediaries report their clients’ tax schemes, are becoming prominent tools in the international fight against tax avoidance and evasion. This Article analyzes the development of MDRs over the past four decades as a global phenomenon with three distinct phases beginning in the 1980s. The analysis reveals several trends: expansion in the types of schemes that are reportable, extension of reporting obligations to a great diversity of intermediaries, and increasing multilateralism in the effort to curb intermediary-enabled tax avoidance and evasion. This Article shows how developments in international tax policy have affected, and will likely continue to affect, the expansion and internationalization of MDRs.

In this Note, I examine whether the complex nature of the U.S. spin-off rules and the burdens associated with successfully navigating such rules discourage conglomerates from breaking up into smaller companies through tax-free spin-offs. First, I argue that there are numerous disadvantages of conglomeration, which generally tend to outweigh any economic benefits derived from the conglomerate form. Next, I describe the statutory and nonstatutory requirements of tax-free spin-offs, evaluating particularly how each requirement may impact a conglomerate wishing to spin off one or more of its business units. Because conglomerates are usually multinational corporations, I also briefly consider the tax consequences of spinning off a foreign company. In the following section, I discuss the issuance of private letter rulings in connection with conglomerate spin-offs and assess whether the I.R.S.’s recent policy changes have accelerated spin-off activity or, to the contrary, whether they have produced a chilling effect on conglomerate spin-offs. Finally, I examine a recent example of a successful conglomerate spin-off—Liberty’s spin-off of TripAdvisor—before analyzing an example of a failed conglomerate spin-off—Yahoo’s attempt to spin off Alibaba. I conclude that, although tax-free spin-offs are occasionally unsuccessful, such failures are rare.

            Even if the tax rules are byzantine and the monetary stakes are exceptionally high, conglomerates wishing to spin off business units typically manage to satisfy the requirements. Therefore, although U.S. tax law does not completely hinder deconglomeration, spin-offs are nevertheless costly. Fulfilling the spin-off requirements leads to economic inefficiencies because it entails expensive pre-spin-off restructuring and delays, as well as high transaction and friction costs.

There exists a paucity of policies and programs that support breast cancer screening in Nigeria. There is a clear need for effective programs that are cognizant of the local realities in Nigeria. The evaluability assessment model can be used as a cost effective and quick alternative to traditional evaluations to improve program practices and management and develop performance measures. This study uses an evaluability assessment to determine if a breast cancer screening program in Lagos, Nigeria was achieving its objectives and to adjust their activities to improve outcomes and processes to optimally serve its community. The evaluability assessment revealed the programs objectives are plausible given its resources and context. Program recommendations focused on improving staff management, developing benchmarks to measure outputs and outcomes, and examining more effective methods of disseminating program information to target population. This study is used as an example of how the six-step evaluability assessment model can be adapted to a multitude of programs to appraise program practices or performance measures.
Our Infected Information Ecosystem, How It Fell Ill, and How We Treat It
Authors: Ruhde Nathan
Published: June 2022

The COVID-19 pandemic has shown how susceptible to misinformation people can be. In the USA, trust in institutions is at an all time low, and that has adverse consequences for the spread of misinformation. Even worse off are social media consumers in foreign countries who navigate a landscape of less policing of misinformation and sometimes faster spreading conspiracy theories and lies. This article suggests that, rather than only focusing on cracking down on misinformation, experts should also think about how providing easier access to medically sound information might help curb misinformation, particularly in the medical arena. Further, this article suggests that medical doctors are best positioned to counter currently rampant misinformation because of the elevated trust they have with the general public.
The Eradication of Guinea Worm Disease: A Push for Community Engagement
Authors: Sharma Radhika , Priven Mariel , Kosinski Karen
Published: June 2022

Guinea Worm Disease (GWD) is a neglected tropical disease caused by the nematode Dracunculus medinensis; it has been targeted for eradication since 1980. With only 14 human cases in 2021, GWD may be the first human parasitic disease to be eradicated, even without a vaccine. Current efforts to eradicate GWD face multiple challenges, the largest of which is the lack of access to safe drinking water. Other challenges include the discovery of animal hosts for D. medinensis and the seasonality of transmission. Interventions to address GWD have included water filtration systems, clean water initiatives, and health education programs, among others. Here, we argue that although enormous progress has been made, many studies fail to include a substantive discussion about community engagement. Past GWD eradication efforts have focused heavily on a vertical approach to health, which does not fully encapsulate the needs of affected communities. After reviewing literature on GWD control between 1985 and 2021, we conclude that a final push towards eradication should involve active community engagement.
Documenting Change from a Conversation Analytic Perspective: Introduction to the Spring Forum
Authors: Lo Carol Hoi Yee , Frantz Kelly Katherine
Published: June 2022

Since its inception, Conversation Analysis (CA), which aims to describe the fine-grained machinery of talk (Sidnell, 2010), has uncovered an impressive range of “member’s methods”—how members of society accomplish social actions. The “lived work” of participants is, in fact, dynamic and complex: Facing new situations and unforeseen contingencies could inform how participants respond to similar situations in the future. And beyond tracing the emergence of new knowledge and practices, our understanding of member’s knowledge can also be extended by charting how novices of a community of practice develop competence and expand their repertoires. After all, novices do not become experts overnight; documenting the trajectories and evolutions of practices can provide important insights into the very process of becoming a competent member.
“It’s Not Scientific Enough”: Analyzing the Development of Academic Criticism in a Graduate Student Writer
Authors: Frantz Kelly Katherine
Published: June 2022

Academic criticism is a fundamental feature of scholarly discourse. It plays a key role in scientific theory building, whereby ideas are iteratively challenged and redrafted (Kuhn, 1962, 1970). It is also how individual scholars create a research space (see the CARS model, Swales, 1990) and establish themselves as members of the research community. Thus, for graduate student writers, the ability to engage in this practice is important for academic success and socialization into the discourse community. However, by definition, students are novices, so they may struggle to assume the role of disciplinary authority required to evaluate others’ works (Dobson & Feak, 2001; Hyland, 2002). Several scholars have explored the linguistic and rhetorical features of academic criticism (Hyland, 2000, 2002; Thompson & Yiyun, 1991) and how it varies across disciplines (Hyland, 2000; Salager-Meyer & Ariza, 2003), often with educational goals in mind (Belcher, 1995; Swales & Feak, 2004). And while some researchers have analyzed criticism in student texts (Cheng, 2006), we know little about how this practice develops over time. Additionally, given that existing studies focus on written criticism, we have yet to explore the nature of spoken criticism and how it is shaped in and through interaction. Thus, this paper adopts a conversation analytic framework to examine how a graduate student writer formulates spoken academic critique during writing consultations and how these formulations change over time.
Socialization of Appropriate Classroom Behavior: A Micro-Longitudinal Conversation Analytic Account
Authors: Hughes Sean
Published: June 2022

According to Garfinkel and Sacks (1970), linguistic development is a fundamental tool by which children become competent members of society. While socialization in the home is key to children’s acquisition of cultural norms, school is another important setting in which children are socialized into their cultural environment (Schieffelin & Ochs, 1986). In this paper, I employ conversation analysis (CA) to examine how young children are socialized towards appropriate classroom behavior by a teacher’s upgraded use of directives, embodied directives, and finally, metacommentary. Specifically, this study focuses on the strategy one teacher uses within the span of a single class to get a misbehaving student to physically move back to her partner during group work.
Crosslinguistic Influence and Second Language Learning
Authors: An Shan
Published: June 2022

The multilingual turn in second language acquisition (SLA) research signals an epistemic reorientation of the field (Ortega, 2014). It manifests the move away from the monolingual bias that measures learner language with the idealized competence of native speakers as the yardstick. In so doing, the focus has shifted to disentangling the cognitive, linguistic, and psycholinguistic mechanisms involved in multilinguals’ language acquisition processes. Crosslinguistic influence (CLI) has been a prominent object of research since the 1980s, and new perspectives have been requested to reflect this multilingual turn (Odlin & Yu, 2016). McManus’s (2022) book, Crosslinguistic influence and second language learning, aims to advance new avenues of theorization and empirical research in CLI to answer the multilingual turn’s call.

A Scoping Review of Formal Care to Children with Special Needs during the Covid-19 Pandemic
Authors: Suvarna Latha Rosaline
Published: June 2022

The Covid-19 pandemic caused an unprecedented closure of direct service for children with special needs (CSNs), which shifted service to remote mode. This scoping review analyzed the strategies adopted by different formal care services for CSNs, their strengths and weaknesses, and the challenges faced by the formal care providers (FCPs). This study identified relevant articles through academic databases and Google searches using appropriate search strings and keywords. It included ten journal articles (n=10) and eight pieces (n=8) of grey literature through a meticulous selection process and extracted data. This review drew results by collating the descriptive numerical data analysis and qualitative thematic analysis and interpreting them. Reporting incorporated all the possible items recommended by the PRISMA-ScR guidelines. This review demonstrated that pediatric rehabilitation adopted the telehealth approach and that special education changed to remote learning. When childcare programs in the USA functioned according to specific guidelines, residential care in South Asian countries faced a financial crunch. FCPs faced personal and professional challenges that required systematic training to deal with pandemic situations. This scoping review made suggestions for relevant policy formulations for equitable and effective service delivery to CSNs during pandemic situations, and it exposed new avenues for research.
