How Do Intercrisis Learning Outcomes Affect Intracrisis Learning? “Learning in the Making” in the Case of South Korea’s COVID-19 Response

This study explores the processes of intercrisis and intracrisis learning and the link between them, drawing on South Korea’s responses to the COVID-19 pandemic as an example. The crisis management literature suggests that intracrisis learning is less likely to occur than intercrisis learning due to inherent barriers that hinder learning and adaptation in the heat of crisis. Based on the conceptual framework of problem-oriented governance and crisis learning, we unpack how prominent outcomes of intercrisis learning facilitate intracrisis learning during the acute phase of an emerging crisis. We postulate that learning after 2015 MERS crisis developed the core capabilities for problem-oriented governance which, in turn, have facilitated learning during the COVID-19 pandemic. We also posit that these capabilities continue to be enhanced through ongoing intracrisis learning processes. Our findings indicate that, in South Korea, such capabilities— reflective-improvement capability, collaborative capability, and data-analytic capability—have been substantially developed after 2015 MERS crisis and are getting more sophisticated as a result of on-going intracrisis learning during the COVID-19 pandemic. Theorical and practical implications for crisis learning are discussed.
Factors Affecting Intention to Purchase Voluntary Pension Insurance in Vietnam

: The research was carried out with the aim to identify factors affecting the intention to purchase voluntary pension insurance in Vietnam. With data collected from 334 subjects across the country, mainly in Hanoi, the results showed that attitude towards risk, subjective norms, percieved behavioral control, past experiences and corporate branding have positive influences on the central factor, which is intent. After quantitative analysis, the study proposes recommendations for businesses to improve their services as well as methods of distribution to meet the needs of potential customers to save in pension funds. Additionally, the study will provide the basis for regulators to come up with measures to promote the retirement insurance market and at the same time, raise public awareness about social security.

REMOTE LEARNING IN THE CONTEXT OF SCHOOL EDUCATION: CHALLENGES AND OPPORTUNITIES

: The COVID-19 pandemic brought a revolution in teaching learning process at all levels of education. School education is not an exception to it. Its impact found all around in varieties of ways. Educational institutions, teachers, teacher educators responded to this situation actively which ultimately forced the students and parents make a transition from conventional mode of classroom teaching learning process to online mode of remote teaching-learning process. A virtual learning environment is created for the students to manage the situation, as there were no other options available. The present piece of work is an attempt to assess the situation of online education (teaching and learning practices at a distance) at school level in Odisha. The findings of the study reflect a comprehensive view of various stakeholders (teachers, students and parents) associated with education of children at school levels and the need for an effective and efficient pedagogy for online education. It also established the fact to strengthen the resources required for making the online teaching learning process effective from the point of view of all stakeholders. The findings of the study also revealed how and why integration of technology (blending) is essential for capacity building of teachers and to support teaching-learning in the context of school education in Odisha. Also, the implications of this study are of very important for designing, development and implementation of online education for quality improvement in school education sustainably.
Applications of Hydrofoils with Leading Edge Protuberances

Abstract : The leading edge modified hydrofoils generally create lift equal to or greater than their baseline counterparts at higher angles of attack (beyond the baseline stall angle) whereas at lower angles of attack the baseline models produce lift coefficients equal to or greater than the modified models. The drag coefficients of all modified hydrofoils are either equal to or greater than their baseline counterparts. The relative increase in drag associated with the leading edge protuberances, in turn, results in the lift-to-drag ratio for the modified hydrofoils to be less than or equal to the baseline models. The incipient cavitation numbers for leading edge modified hydrofoils were consistently greater than their their baseline counterparts.
Intravenous versus perineural dexmedetomidine as adjuvant in adductor canal block for total knee arthroplasty

Background The shivering effect after spinal anesthesia in total knee arthroplasty (TKA) is challenging for anesthesiologists. This study aimed to compare two administration routes of dexmedetomidine as a post-neuraxial shivering prevention measure and an adjunctive analgesic and sedative agent. Methods Fifty-six patients were randomly allocated into two equal groups. The intravenous dexmedetomidine (IV dex) group received an IV infusion of 0.5 µg/kg dexmedetomidine diluted in 20 ml saline and an adductor canal block (ACB) consisting of 20 ml of 0.25% levobupivacaine and 1 ml saline. The adductor canal block dexmedetomidine (ACB dex) group received a 20 ml IV infusion of saline and an ACB consisting of 20 ml 0.25% levobupivacaine and 1 ml of 0.5 µg/kg dexmedetomidine. Results The incidence of shivering 1 h post spinal anesthesia was equal in both groups (50%); however, the shivering grade was significantly lower in the IV dex group 1 h postoperatively. The onset of sensory block was significantly later in the IV dex group (22.14 ± 2.52 min) than in the ACB dex group (12 ± 3.31 min). Postoperative analgesic duration (h) was significantly longer in the ACB dex group (12.28 ± 4.47) compared to the IV dex group (9.28 ± 1.90). The sedation scores were also significantly higher in the IV dex group in the preoperative, intraoperative, and immediate postoperative periods. Conclusions While perineural ACB dexmedetomidine had similar intraoperative anti-shivering with less sedative effects as IV dexmedetomidine, it was associated with both less shivering control and superior analgesia post-TKA under spinal anesthesia.
Communicating Artificial Intelligence through Newspapers: Where is the Real Danger?

: This study attempts to explore how newspapers are portraying the impact of Artificial Intelligence, while considering the social and economic contexts where these new developments are unfolding. Thus, the research analyses articles from four English languaged newspapers. First it looks into the sample for the ‘voices’ or sources that journalists are relying on when writing on this issue and secondly, it analyses the articles more in depth to uncover how the narratives and discourses around the short-term effect and long-term effects of AI are being constructed in the news.
LPG–diesel engine

The authors used the dual fuel method to experiment with the use of LPG, mainly butane, as the main fuel of diesel engines to reduce soot and to maintain high thermal efficiency. LPG was injected in the direction of the intake valve directly as a spray to prevent knocking and to maintain high charging efficiency. The newly developed electronic fuel injection provided accurate fuel control and injection timing. As a result, the dual fuel operation produced high thermal efficiency almost identical to that of diesel engines. Soot in the engine exhaust was almost negligible. The mean effective pressure of 0.6 MPa was obtained with LPG and only a small amount of gas oil, in spite of the high compression ratio of 17 for gas engines. Increasing the proportion of gas oil resulted in maximum output from the engine and almost no soot output. Moreover, mordenite catalyser reduced by 20% the NOx in the exhaust gas, and THC functioned as a reducing agent for NOx simultaneously.
The use of supply chain management to reduce delays as result of pre-construction deficiencies in Malaysian public sector construction projects

This thesis examined the delay causes of Malaysian public sector projects. Using a systematic approach, the researcher identified the main delay factors and categorised them into pathogens. The pathogens were matched with beneficial Supply Chain Management (SCM) tools and developed into a holistic SCM framework to facilitate improvements in Malaysian public sector projects. The researcher concluded that SCM is the potential saviour for the delay dilemma and that it is necessary for the Malaysian government to initiate the revolutionary practice.
Transport and Fate of All-Time Released Plastics in the Global Ocean

Mismanaged plastics accumulate in oceans and threaten marine life. About 40 million tonnes of plastics have reached the oceans, where their fate remains unclear. To track the sources, sinks, sizes, and age of all-time released plastics, we developed a new mechanistic model and synthesized decades of measurements. We find that Asian plastics are the largest contributor (76%) to marine plastics by mass but only affect the North Pacific and the Indian Ocean, whereas plastics from fishing and shipping activities contribute 24% by mass but cover 60% of the ocean surface. Using the model, we demonstrate that biologically productive nearshore (63%) or upper ocean (25%) ecosystems trap 88% of the marine plastic. This study provides a model framework to assess the potential effect of future mitigation strategies.
Phantom Reactivity in Organic and Catalytic Reactions as a Consequence of Microscale Destruction and Contamination-Trapping Effects of Magnetic Stir Bars

Magnetic stir bars are routinely used by every chemist doing synthetic or catalytic transformations in solution. Each bar lasts for months or years, as the regular PTFE (polytetrafluoroethylene) coating is believed to be highly durable, inert, and resistant to multiple washings and cleanings. By using electron microscopy, we found out quite unexpectedly that the surface of magnetic stir bars is susceptible to microscale destruction and forms various types of defects. These microscopic defects effectively trap and accumulate trace amounts of active components from reaction mixtures, most notably metal species. Trapped in surface defects, the impurities escape elimination by washing and cleaning, thus remaining on the surface. FE-SEM/EDX analysis shows that the surface of used stir bars is littered with contaminants representing a variety of metals (Pd, Pt, Au, Fe, Co, Cr, etc.). ESI-MS monitoring corroborates the transfer of the trace metal species to reaction mixtures, while chemical tests indicate their .
The role of supplementary calcium in submaximal exercise and endurance performance.

Epidemiological data suggest a positive relationship between increased calcium intake and decreased fat and total body mass in healthy people (McCarron et al. 1984, Davies et al., 2000). An in-vitro model suggesting the role of cyclic Adenosine Monophosphate (cAMP) and phosphodiesterase 3B (PDE 3B) has been implicated in the relationship between calcium and lipolysis (Xue et al., 2001). The objective of the series of studies presented in this thesis was to investigate the ergogenicity of supplementary calcium in endurance exercise via studying its influence on substrate metabolism and body composition. Study 1 examined the effects of four weeks of calcium (citrate) supplementation (1000 mg elemental calcium/day) on 60 minutes of cycling at a submaximal intensity of 50%Wpeak. The results of this study indicated that calcium supplementation significantly improved body composition of the participants with a greater fat loss and increased lean mass observed in highly trained athletes as compared to the recreationally trained participants. In addition, four weeks of calcium supplementation also showed an enhanced trend of availability of fatty substrates in the plasma and consequently an increased trend towards higher fat oxidation during submaximal exercise. Study 2 and 3 thus examined the effects of calcium supplementation directly on performance during endurance events (25 and 10 mile cycling time trials (TT)) in highly trained athletes. Results from these studies indicate that following calcium supplementation there was a meaningful improvement in power output (PO) (~4%) during the 25TT and ~2.7% in 10TT with corresponding better completion times in both the time trials. This amounts to an increase in ~2-3% higher PO%peak and ~3-5% increase in power output at lactate threshold, with the higher percentages attributable to the 25TT and the lower end to the 10TT. This increase in PO was achieved without the corresponding increase in oxygen consumption, thus significantly improving the gross efficiency of the cyclists. In addition, four weeks of calcium supplementation once again exhibited the same trends in body composition as observed in study 1 of decreased fat mass and a concurrent increase in lean mass. The results from this set of investigation indicate that calcium plays a multifactorial role in performance enhancement of endurance events. This may have been achieved via a combination of influence on substrate metabolism and body composition. The impact of calcium on fatigue mechanisms and vascular tone may have also played a part in increasing PO and thus efficiency of the athletes. Thus the potential of calcium to enhance performance needs further investigation in studies with larger sample sizes and different training status of athletes.
Leader and Team Adaptation: The Influence and Development of Key Attributes and Processes

Abstract : This report summarizes the results of a series of investigations that examined (a) the role of feedback processes as a leadership tool in team adaptation, (b) the influence of developmental work experiences on team and leader adaptability, and (c) the effects of combinations of leader qualities on the display of adaptation processes and performance in dynamic military and business settings. The results of these investigations indicated that (a) process-oriented, team level, and public feedback from leaders was most effective in facilitating team adaptation, particularly when team members possess high levels of cognitive skills; (b) developmental assignments are associated with growth in social competencies, but only when participating leaders have high levels of metacognitive skill, cognitive complexity, and tolerance for ambiguity; (c) social competencies influence leader adaptability, but only when the organizational climate supports innovation; and (d) several cognitive, social, and dispositional leader attributes were related singly and in combination to leader adaptability.
Chronology for Mississippian and Oneota Occupations at Aztalan and the Lake Koshkonong Locality

The Middle Mississippian component at Aztalan was a mixed, Late Woodland / Mississippian occupation sited within a heavily fortified habitation and mound center that is located on a tributary of the Rock River in Wisconsin. It represents the northernmost large Cahokian-related village recorded. The Oneota Lake Koshkonong Locality of the Rock River drainage is located approximately 20 km south of Aztalan, and it consists of a 25 km2 area along the northwest shore with a small cluster of habitation settlements. Sixty-eight radiocarbon measurements have been obtained from Aztalan, and 52 from Oneota settlements in the Lake Koshkonong Locality. We discuss how to best interpret this dataset, and we use Bayesian chronological modeling to analyze these dates. The results suggest that (1) Aztalan's Late Woodland (Kekoskee phase) occupation began in the AD 900s or early AD 1000s, (2) Aztalan's Mississippian occupation ceased in the AD 1200s, (3) Oneota occupations at Lake Koshkonong began after AD 1050 and were established by the AD 1200s, and (4) Oneota occupations at Lake Koshkonong continued after Aztalan's Mississippian abandonment until at least the late AD 1300s. Additionally, the results demonstrate that Aztalan was fortified with a palisade with bastions for much of the Mississippian occupation, suggesting a contested presence in a multiethnic landscape.
The periodic table – an experimenter’s guide to transactinide chemistry

Abstract The fundamental principles of the periodic table guide the research and development of the challenging experiments with transactinide elements. This guidance is elucidated together with experimental results from gas phase chemical studies of the transactinide elements with the atomic numbers 104–108 and 112–114. Some deduced chemical properties of these superheavy elements are presented here in conjunction with trends established by the periodic table. Finally, prospects are presented for further chemical investigations of transactinides based on trends in the periodic table.
Microbiota composition of the dorsal patch of reproductive male Leptonycteris yerbabuenae

Bacteria and other types of microbes interact with their hosts in several ways, including metabolic pathways, development, and complex behavioral processes such as mate recognition. During the mating season, adult males of the lesser long-nosed agave pollinator bat Leptonycteris yerbabuenae (Phyllostomidae: Glossophaginae) develop a structure called the dorsal patch, which is located in the interscapular region and may play a role in kin recognition and mate selection. Using high-throughput sequencing of the V4 region of the 16S rRNA gene, we identified a total of 2,847 microbial phylotypes in the dorsal patches of eleven specimens. Twenty-six phylotypes were shared among all the patches, accounting for 30 to 75% of their relative abundance. These shared bacteria are distributed among 13 families, 10 orders, 6 classes and 3 phyla. Two of these common bacterial components of the dorsal patch are Lactococcus and Streptococcus. Some of them—Helcococcus, Aggregatibacter, Enterococcus, and Corynebacteriaceae—include bacteria with pathogenic potential. Half of the shared phylotypes belong to Gallicola, Anaerococcus, Peptoniphilus, Proteus, Staphylococcus, Clostridium, and Peptostreptococcus and specialize in fatty acid production through fermentative processes. This work lays the basis for future symbiotic microbe studies focused on communication and reproduction strategies in wildlife.
High-Speed Ground Transportation Noise and Vibration Impact Assessment

This report is the second edition of a guidance manual originally issued in 2005, which presents procedures for predicting and assessing noise and vibration impacts of high-speed ground transportation projects. Projects involving high-speed trains using traditional steel-wheel on steel-rail technology as well as magnetically levitated (maglev) systems are included. Procedures for assessing noise and vibration impacts are provided for different stages of project development, from early planning through preliminary engineering and final design. For both noise and vibration, three levels of analysis are described including a preliminary impact screening, a general assessment and a detailed analysis. This updated guidance contains models for predicting high-speed train noise and vibration as well as criteria for assessing the magnitude of potential impacts. A range of mitigation measures are described for dealing with adverse noise and vibration impacts. There is a discussion of noise and vibration during the construction stage and also a discussion of how the technical information should be presented in the Federal Railroad Administration’s environmental documents. This guidance will be of interest not only to technical specialists who conduct the analyses but also to project sponsors, Federal agency reviewers, and members of the general public who may be affected by the projects.

Stigma and utilization of treatment for perinatal depression among adolescents in Nigeria

Background. Depression is a common and serious disorder among low-income adolescent mothers in low-and middle-income countries where resources for treatment are limited. We wished to identify, among adolescents with perinatal depression and their health providers, factors influencing health service utilization for the condition in Nigeria to inform new strategies of care delivery.Methods. Focus group discussions (FGDs) were carried out among low-income adolescent women with a history of perinatal depression and separately with primary care clinicians treating this condition in Ibadan, Nigeria. Semi-structured interview guides were used to obtain views on the factors that promote or hinder help-seeking and engagement. FGDs were conducted until saturation of themes was achieved. Transcripts were analyzed using content analysis framed by the Behavioral Model for Vulnerable PopulationsModel and triangulation between patients and providers. Results. A total of 17 women and 25 care providers participated in 6 FGDs. Perceived benefits of treatment received for perinatal depression were strong motivation for service utilization. Significant stigma regarding adolescent pregnancy and perinatal depression created obstacles to care. Providers expressed negative stereotypes associated with adolescent pregnancy. However, individual patient resilience was a major enabling factor facilitating service engagement. Older and more experienced care providers were perceived to deliver more tolerant and supportive care that adolescent mothers valued. Conclusions. Participants identified an unsupportive and stigmatizing clinic environment as a major barrier to accessing available care. Interventions to reduce stigma among healthcare providers may improve services for this vulnerable population.
