The impact of the COVID 19 pandemic on stock market volatility: evidence from a selection of developed and emerging stock markets

This study examines the impact of the COVID 19 pandemic on the stock markets of China, India, Pakistan, the UK and the US using Generalised Autoregressive Conditional Heteroscedasticity (GARCH) and Threshold GARCH models with COVID 19 as an exogenous dummy variable in the variance equation. The sample period of 2016–2021 is divided into two sub-periods: the pre-COVID 19 period and the COVID 19 period. The results of the study indicate that there was persistent volatility in these markets and that this volatility increased as a result of the pandemic. In addition, the Threshold GARCH results indicate that the asymmetric term was significant in all markets indicating that bad news, such as the pandemic, had a stronger impact on the conditional variance of the returns as compared to good news. In addition, the results further confirm that the US market had no significant impact on the volatility of the Chinese market during the pandemic. The results have important implications for (1) international investors regarding portfolio management and investment risk minimisation in situations like the COVID 19 pandemic; and (2) policy-makers in terms of how they respond to any future pandemic.

Calciphylaxis of the Penis in a 70-Year-Old Man: A Case Report

Penile calciphylaxis is a severe form of calcifying uremic arteriolopathy, with only a few cases reported in the literature. It is uncommon, characterized by calcification within the walls of small vessels, resulting in ischemic changes to the skin, and is most commonly seen in patients with end-stage renal failure (ESRF). We reported a 70-year-old patient case of chronic ESRF on hemodialysis and type 2 diabetes who presented with painful blackish necrotic discoloration of the peri-meatal area and dry gangrene at the big toe of the right foot. The patient was treated with penile debridement, penile stump necrosectomy, and broad-spectrum antibiotics. The patient was diagnosed with penile calciphylaxis based on histopathological findings. This episode occurred again in postoperative follow-up and required regularization of the penile stump. In conclusion, the management of this rare situation is controversial, and its diagnosis is still difficult due to the scarcity of reported cases.

Remote Sensing and GIS-Based Accuracy Assessment of LULC Map and Landslide Susceptibility Prediction for Meghalaya, India

ABSTRACT Through this study, a Landslide Susceptibility Map (LSM) has been developed for the Meghalaya state, India using an Analytical Hierarchy Process (AHP). According to a 2012 Geological Survey of India report, the annual average number of landslides in Meghalaya is nearly 30, which is due to a combination of mountains, steep slopes, and excessive rainfall, leading the state to suffer a huge loss of life and property from landslides. For effective management of the current landslide situation, information about prior landslides is needed. Therefore, the landslide inventory map is prepared with 380 previously occurred events. The Landslide inventory records were separated into training samples (70%) and testing samples (30%) for the purpose of validation. In this regard, the present study has 15 conditioning factors, i.e., slope, rainfall, elevation, relative relief, aspect, distance from the road, curvature, distance from the stream, LULC, lineament density, geomorphology, geology, NDVI, MSAVI, NDWI, which are used to develop susceptibility map. Classification and accuracy assessment of LULC is carried out with segregation as 77% vegetation, 16.4% range land, 3.1% built area, 2.8% crops, 0.4% waterbodies, and 0.3% others (bare land, flooded vegetation, etc.). The Kappa for LULC categorization is 0.92, which is quite satisfactory and suggests that the LULC categorization is reliable. The developed susceptibility map is classified into four different classes, low susceptibility (35%), moderate susceptibility (41%), high susceptibility (20%), and very high susceptibility (4%), and has been verified using physical and Receiver Operating Characteristics (ROC) techniques. Results show that anticipated susceptibility classes are in good match with previous landslide events. The prepared map is reliable and can be used for land-use planning of the state in the future.

Introduction: Bunaken Island still lacks proper waste management infrastructure, resulting in the accumulation of garbage around residences and along the coastline. This prevalent issue significantly impacts public health and the overall quality of life on the island. The research seeks to evaluate the waste management situation on Bunaken Island and identify suitable locations for waste disposal. Methods: The study employed random sampling techniques to select households within the study area for primary data collection. The research utilized Boolean and spatial analysis methods to pinpoint appropriate waste disposal zones and propose sustainable waste management strategies for Bunaken Island. Results and Discussion: Findings revealed that Bunaken Island spans a land area of 794.12 hectares and is inhabited by a population of 3,843. The analysis identified two recommended locations for final disposal zones, totaling 3.40 and 0.45 hectares, respectively. Moreover, the estimated waste generation over the next decade is approximately 4,277,893 kilograms, necessitating 0.0241 hectares of land for waste accommodation through terracing methods. Conclusion: Addressing this issue requires the identification of two viable disposal zones in distinct locations. Additionally, implementing recycling practices to utilize both organic and inorganic waste from local and marine sources and promoting reuse before landfill disposal are crucial strategies for effective waste management on Bunaken Island.

Study on Class Management Change and Teacher Orientation under the Vision of Artificial Intelligence

With the rise of artificial intelligence (AI), class management is experiencing unprecedented changes, but it is also facing certain risks and tests. It is of great practical significance to clarify the class management changes and teacher orientation under the vision of AI. Since the application of AI in the field of education, class management has realized the burden reduction and efficiency increase under the ability of technology, and has changed from the traditional mode of standardization, one-sided and unitization to a personalized, systematic and diversified intelligent mode, which provides great convenience for the management of class teachers. However, at the same time, the rise of AI has also caused a series of dilemmas such as the disclosure of students’ privacy and the challenge of the main value, which has put forward higher requirements for teachers’ literacy, positioning and management. Based on this, this paper puts forward the orientation of teachers in class management under the vision of AI. Teachers should improve their intelligent application literacy and boost the level of class management. Teachers should reasonably reflect on intelligent technology and grasp the applicable management situation. Teachers should fill the gaps in intelligent management and pay attention to humanistic emotional assistance to promote the positive integration of AI and class management.

The Astroworld tragedy as an argument for proactive crisis management

PurposeThe Astroworld concert tragedy is used as an example of crisis (mis)management and the potential utility of the 4R model. Although the 4R model has been implemented in high-risk emergency management situations, it is useful in the PR field because of its actionable approach, creating a way for practitioners to prepare for and manage crisis situations.Design/methodology/approachThis is an analysis of the crisis that occurred at Astroworld, spanning preparation, day-of events, casualties and enduring reputational impact. The paper applies the 4R method to the Astroworld tragedy to show how it could have lessened or even prevented the tragedy. Finally, the SCCT model is used to explain why the official post-crisis statements were ineffective.FindingsSocial media has heightened the importance of a quick and effective organizational response to risk and crisis situations because poor responses can go viral quickly. However, social media also provides intelligence and crowd sourced information that can inform PR practitioners of emerging crisis scenarios. It is also an underutilized tool for two-way communication during crises.Practical implicationsThe 4R approach is beneficial to general practitioners as it simplifies crisis best-practices, something essential for quick action. As our world changes and becomes less predictable, practitioners must have a clear plan to protect their organizations and the public surrounding them. This approach includes reduction, readiness, response and recovery, which are all essential in crisis communication.Originality/valueThe 4R method has not been explored or applied in the PR field. This paper highlights how the model has been utilized in the emergency management field and illustrates the way 4R can serve the PR field.

Opportunities and challenges for circular economy in the Maldives: A stakeholder analysis of informal E-waste management in the Greater Malé Region

In the Maldives, the contribution of the informal sector to e-waste management is significant as a formal e-waste management system is not yet established. The opportunities for advancing the circular economy in the Maldives’ e-waste sector rely on the possibility of its formalization. This study aimed to examine the current and anticipated situations of e-waste management in the Greater Malé Region of the Maldives, with a specific focus on formalizing the informal sector. Interviews and questionnaire-based surveys were conducted followed by statistical analysis of the data. The t-test performed for the consumer survey data (n = 202) suggests that formalization encourages consumers to engage with the informal sector, resulting in increased resource recovery. Thematic analysis of interviews conducted with both formal and informal sector stakeholders (n = 17) revealed that the informal sector plays a substantial role in managing e-waste. It also underscored the need for government assistance to enhance safety and productivity in this sector. Various opportunities and challenges for establishing a circular economy in the country were identified, such as the rise in e-waste generation, the presence of an active informal workforce, the lack of sufficient government support, and prevailing stereotypes among consumers regarding informal workers. These findings provide a fresh perspective on the solutions for waste management in the Maldives and open the door to further explore the significance of the informal sector and feasible formalization initiatives. This study could contribute to the literature on the role of the informal sector in waste management in the Maldives and other small island developing states.

Seasonal climate forecast-an important tool in managing the risk of extreme weather events in Australia's wheat industry

This study aims to investigate the benefits of using the Australian Community Climate and Earth-System Simulator-Seasonal Version 2 (ACCESS-S2), a state-of-the-art seasonal climate forecast (SCF) system, to improve contingent decision-making in the Australian wheat industry. Six locations in eastern Australia, three cultivars with varying maturities, and 17 times of sowing (TOS) were considered. Seasonal hindcasts from ACCESS-S2, initialized on the 1st May for the period 1981–2018 were linked with the Agricultural Production System sIMulator (APSIM)-Wheat model (v7.10) to (1) assess the hindcast skill of ACCESS-S2 in predicting the occurrence of extreme weather events and in predicting above/below long-term median wheat yield; (2) identify optimal management strategies in mitigating the impact of extreme weather events; and (3) quantify the yield benefit of using ACCESS-S2 at the key decision-making point of sowing against a baseline management situation (i.e., without the use of SCF). Research results showed that (1) ACCESS-S2 has varying skills in predicting extreme climate indices and wheat yield across the six locations at a seasonal lead time; (2) 68 % of cases had a yield gain using SCF information; (3) across all cases, there was an average yield gain of 281 kg/ha representing an increase of 13 %; (4) benefits of using SCF were seen across predicted wet years, neutral years and dry years accounting for 69 %, 65 % and 72 % respectively, and (5) the identified optimal management options varied from location to location with earlier sowing associated with either suntop or gregory or both being the optimal strategies at most of the locations considered. Overall, there is a demonstrated benefit in utilizing ACCESS-S2 forecasts in the Australian wheat industry to improve farm management decision-making. The benefit can occur in any climate state but with dry years being more likely and significant (with an average yield increase of 97 % across the locations).

A rare case of impacted mandibular distomolar: Identification and management at a remote high altitude location

Planning the surgical extraction of an impacted supernumerary tooth poses a very peculiar problem for a dental professional. The management of this unique clinical situation is quite challenging and requires meticulous preparation, especially in a remote high altitude regions. Supernumerary teeth are those which are present in excess of the normal permanent or deciduous dentition in the oral cavity. A distomolar, also commonly known as the fourth molar, is a supernumerary tooth located distal to the third molars. The occurrence of supernumerary teeth is much more frequently observed in the maxillary arch as compared to the mandible. While the distomolar is quite infrequently observed, its occurrence in the mandible is even rarer. In this article, we present an overview of distomolars along with a case report on the management of a symptomatic mandibular distomolar at a remote setup in Tangtse region of the Union Territory of Ladakh.

Business as usual like never before! Continuity, rupture and anxiety management in the 2014 Scottish independence referendum campaign

Ontological security-seeking has traditionally been considered to rest upon the stability and continuity of core auto-biographical narratives and everyday routines. ‘Critical situations’ which fundamentally destabilise these foundations of ontological security have thus hitherto carried a negative valence. Constitutional referenda proposing a radical re-organisation of collective political identities and daily life, therefore, are intriguing. A source of severe consternation for some, for others, potential change is positive, even thrilling. This article investigates this puzzling contrast, drawing on Ontological Security Studies’ (OSS) recent recentring of Existentialist thought and debates exploring the heterogenous potential of anxiety, and utilising the 2014 referendum on Scottish independence and the strategies for anxiety management embedded in the pro-independence ‘Yes’ campaign. Through analysis of dominant discourses grounding the argument for independence, findings demonstrate the simultaneous deployment of contradictory anxiety management strategies: independence was framed as a pathway to escape the instability and uncertainty of the status quo; as a pathway to continuity; and as a chance to embrace anxiety, to relish the opportunity and excitement of change. This article thus contributes to the prevailing critique of OSS’ over-privileging of stability and continuity in ontological security-seeking, yet problematises ‘either/or’ approaches to understanding anxiety management in critical situations and beyond.

Risk management of emergency situations caused by flooding of built‐up mountain areas

The purpose of this research work is to develop scientific approaches to solving the problem of increasing the sustainability of urbanised territories through flexible regulation of the groundwater regime. The development of a management solution for flexible regulation is carried out on the basis of the application of methods for solving problems of incorrectness.Materials for the study were data from the study of dangerous hydrogeological processes, systematised, among other matters, based on the results of monitoring natural emergencies at the Research Institute for Civil Defense and Emergency Situations. The approach proposed by the authors is based on the application of a set of methods, including methods of: system analysis, forecasting, numerical modeling, followed by the development of an optimal management solution of emergency situations at the municipal level.As a result of the numerical modeling carried out in the work, the variants of drainage systems and their operating mode are determined within the framework of the implementation of the proposed approach in the simulation mode. This makes it possible to increase the level o f environmental safety of historically developed built‐up areas, including mountainous ones.The article presents a new approach to managing the risk of emergencies in case of flooding of buildings and structures in built‐up mountainous territories, including historical territories. In such territories, the watered soil preserves the cultural layer, which determines the need for flexible regulation of the groundwater regime. The results of the study are used in carrying out research work of the State Research Institute of the Russian Academy of Sciences (GOChS) on the study of dangerous hydrogeological processes and their impact on the environment, life safety, stability of the functioning of economic facilities, monitoring and forecasting of natural emergencies.

Perception of Violence by Psychiatric Nurses: Behind the scenes

IntroductionViolence in psychiatric settings poses significant challenges for healthcare professionals, particularly nurses. This study examines psychiatric nurses’ perceptions of violence and its impact on the quality of care they provide.ObjectivesThe primary objective is to assess the influence of violence on the quality of care in psychiatric settings, with a focus on the experiences and perspectives of nurses.MethodsWe employed a questionnaire-based survey administered to 30 psychiatric nurses working in both inpatient and outpatient psychiatric units of the Razi hospital Manouba. The survey gathered information on the prevalence of violence, types of violence encountered, and the impact on nursing practice.ResultsOf the 30 respondents, 75% identified as female and 25% identified as male. Most of them had more than five years of experience. The primary results revealed that all the psychiatric nurses reported experiencing at least one incident of violence during their psychiatric nursing careers. Regarding exposure to verbal violence, the results indicated that 52% encountered it sometimes, 22% often, 17% very often. Regarding physical violence, 30% experienced it rarely, 26% sometimes, 13% often, and 13% very often. For sexual violence, 56% reported never experiencing it, 8% rarely, 26% sometimes, and 8% very often. These incidents had varying effects on nurses’ emotional well-being, job satisfaction, and the quality of care they were able to provide. 53% of nurses reported experiencing emotional distress and feelings of anxiety as a result of violence, 13% felt anger and frustration. One nurse declared he was not affected emotionally. Most of the respondents (75%) indicated that their job satisfaction had been negatively affected by violent incidents. 40% of respondents stated that violence has a negative impact on their relationship with patients, but they make efforts to maintain care quality. Whereas, 20% found ways to strengthen connections despite challenging experiences.The most commonly endorsed strategies to cope with violence included attempting to master their emotions by remaining calm and patient (78% of respondents), seeking assistance or the presence of other healthcare team members (65%), and maintaining a safe distance from patients (69%). Fewer participants reported raising their voice and adopting a position of authority (30%), while a minority indicated engaging in additional training on the management of violent situations (20%). These results illustrate the diverse range of personal coping strategies.ConclusionsViolence in psychiatric settings has a multifaceted impact on psychiatric nurses, affecting both their emotional well-being and the quality of care they provide. Strategies for managing and preventing violence, as well as supporting nurses in coping with these challenges, are essential for maintaining high-quality psychiatric care.Disclosure of InterestNone Declared
