Biggest Crisis Research Articles

Analisis Kepemimpinan Rasulullah Dalam Perspektif Pendidikan Agama Islam

The biggest crisis in the world today is the crisis of example or uswah. The need for a leader who has character like the Prophet Muhammad is very necessary because many people who serve as leaders do not have the character that a leader should have in terms of educational leadership. Leadership is the characteristic of a leader in assuming formal moral and legal responsibility for all the implementation of his authority which has been delegated to the people he leads. As an exemplary leader who is an ideal model of leadership, Rasulullah was gifted with four main characteristics, namely: Sidiq, Amanah, Tablighi and Fathonah. Sidiq means honest in words and deeds, amanah means being trustworthy in maintaining responsibilities, tablig means conveying all kinds of goodness to the people and fathonah means being intelligent in managing society

Detection of COVID-19 Disease with Machine Learning Algorithms from CT Images

COVID-19, caused by the SARS-COV-2 virus, which has killed more than 6 million people, is one of the most contagious diseases in human history. It has seriously affected every area that people come into contact with, from business life to economy, from transportation to education, from social life to psychology. Although the developed vaccines provide a partial decrease in the number of deaths, the mutations that the virus constantly undergoes and the increase in the transmission rate accordingly reduce the effectiveness of the vaccines, and the number of deaths tends to increase as the number of infected people. It is undoubtedly important that the detection of this epidemic disease, which is the biggest crisis that humanity has experienced in the last century after World War II, is carried out accurately and quickly. In this study, a machine learning-based artificial intelligence method has been proposed for the detection of COVID-19 from computed tomography images. The features of images with two classes are extracted using the Local Binary Pattern. The images reserved for training in the dataset were used for training machine learning models. Trained models were tested with previously unused test images. While the Fine K-Nearest Neighbors model reached the highest accuracy with a value of 0.984 for the training images, the highest accuracy value was obtained by the Cubic Support Vector Machine with 0.93 for the test images. These results are higher than the deep learning-based study using the same data set.

Wicked Solutions for Wicked Problems

“Wicked problems” are often thought of as a situation that should not exist or an inescapable consequence of complex systems. This paper argues for a paradigm shift in instead understanding wicked problems as feedback from the system (i.e., the real world), resulting from a misalignment between our mental model of the system and the system itself, rather than inevitable outcomes of complex systems. Through a systems literature review (SLR) on effective policy and two surveys sampling the US population in order to understand how people are thinking about today’s biggest crises, this paper explores the prevalence of this traditional approach to problem solving. Essentially, wicked problems are the real-world system informing us that our mental model is flawed. When confronted with wicked problems involving webs of causality (as all wicked problems do), people often fail to recognize the needed solutions as a corollary web of actions, instead emphasizing linear causal relationships, or “root causes.” This problem-solving approach has significant consequences, as it overlooks the symmetry between the web of causality generating the problems and the web of solutions that would remedy them. This oversight leads to the implementation of partial solutions divorced from the dynamacy of interaction effects, which in turn leads policy and decision makers to conclude that critical parts of a web of solutions have been ineffective, and thus excluding them from future interventions. This is especially relevant for influential policy makers, planners, and decision makers. However, changing this mindset is in itself a wicked problem. The traditional approach to problems and systems is ineffective, necessitating a more systemic approach to policy. Our statistically significant findings confirm the prevalence of the traditional approach, prompting the recommendation for a more holistic education in critical analysis and systems thinking to address the web of causes that produce “wicked problems.” This is particularly critical for individuals being trained for careers in policy and planning.

Stock Valuation and Dividend Policy Decision of PT ELSA INDONESIA, TBK

Oil shortages began in 2015 due to underinvestment caused by ESG policy. Oil firms need the funds to finance their new refinery, rig, and exploration since most western countries are switching from oil to alternative energy. Geopolitical and economic instability, fear of a downturn, and rising inflation have harmed the worldwide Oil and Gas services market Since Russia invaded Ukraine in 2022, oil prices rose to USD122/barrel for WTI and USD128/barrel for Brent. WTI fell to USD80/barrel and Brent to USD86/barrel by 2022, despite mid-year volatility. PT Elnusa Tbk is an integrated oil services company through its subsidiaries, offers services that include geophysical data, drilling, and oilfield services. The objective of this research is proposes to evaluate the financial performance, valuation and making a recommendation for ELSA regarding its cash. Two methods of valuation are utilized to estimate ELSA’s intrinsic value: absolute valuation and relative valuation. Discounted Cash Flow to the Firm (DCF) model is used for absolute valuation, meanwhile Price to Book Value (PBV) and Price to Earning Ratio (P/E Ratio) methods are used for relative valuation. Dividend policy and buyback share projection is conducted to find the best decision for ELSA. By referring to absolute valuation, ELSA’s intrinsic value is estimated at IDR639/share. By referring to relative valuation using PBV and P/E methods, ELSA’s intrinsic value is calculated at IDR 564/share . These numbers are significantly higher than ELSA’s current price at IDR 378/share, thus providing relatively high margin of safety.in the following stage ELSA will keep on paying dividends to the shareholders. With ELSA DPR 33,25% in 10 years ELSA will have 4,756,289 million in 10 years and the cash could be for management risk if a big crisis or force majeure.

Dual Axis Solar Tracker Using Arduino

Abstract: The biggest crisis we are heading into is the climate change due to excessive use of fossil fuels and to overcome these issues, we have only one solution that is utilizing Renewable Energy. Renewable energy is a type of energy that is harnessed from the nature without causing ill effects to the environment. One of the most prominent kinds of renewable energy is solar energy. The output electrical energy depends on the amount of sunlight falling on the solar panel. Traditionally, solar panels are fixed and the movement of sun over the horizon means that the solar panel does not harness maximum energy most of the time. In order to maximize the power from the solar panel, the panel should face the sun all time. In Arduino based solar tracker with the help of LDR and servo motor is used to generate maximum power.

Evaluation of the influence of the COVID-19 pandemic on the financial stability of airlines with different business models

The Russian airline market became the first in the world to record the positive revenue growth per passenger-kilometer in 2021 after a sharp decline in passenger traffic a year earlier. This indicates its gradual recovery after the biggest crisis in the history of aviation. The purpose of the article is to assess the financial stability of the Russian airlines over the past three years: 2019 (pre-COVID-19), 2020 (COVID-19) and 2021 (post-COVID-19) based on the applying of the three bankruptcy likelihood prediction models (Altman’s Z-score model for emerging markets, the AIRSCORE model of Chow et al., and the P-model of Pilarski and Dinh). The analysis was conducted for the 4 airlines - Aeroflot, Pobeda, Smartavia and NordStar - each of them having a different business model that they follow (national flag carrier, low-cost carrier, ultra-low-cost carrier and regional carrier, respectively). It should be noted that during the study period there was the rapid growth of low-cost carriers, even during the COVID-19 crisis. Traditional (full-service) airlines, on the contrary, had negative dynamics both in terms of operational and financial indicators. Calculations of bankruptcy models showed that low-cost airlines were more financially stable during the COVID-19 pandemic, while full-service air carriers experienced uncertainty during 2020 and only gradually recovered in 2021.

Solar Panel and Main Line Distribution System Control and Monitoring with IOT

Abstract: Energy plays a pivotal role in our daily activities. The degree of development and civilization of a country ismeasured by the amount of utilization of energy by human beings. Energy demand is increasing day by day due to increase in population, urbanization and industrialization. The rate of energy consumption is increasing; supply is depleting resulting in inflation and energy shortage. The biggest crisis we are handling into is the climate change due to excessive use of fossil fuels and to overcome these issues, we have only one solution that is utilizing renewable Energy. One of the most prominent kinds of renewable energy issolar energy. The goal of this thesis was to develop a laboratory prototype of a solar tracking system, which is able to enhance the performance of the photovoltaic modules in a solar energy system. The operating principle of the device is to keep the photovoltaic modules constantly aligned with the sunbeams, which maximizes the exposure of solar panel to the Sun’s radiation. As a result, more output power can be produced bythe solar panel.

Impact of the Covid-19 pandemic on air transport

ObjectivesThe purpose of this article is to present the impact of the Covid-19 pandemic on the operation of airlines and the aviation sector as a whole. The pandemic forced airlines to make many changes in their operations and greatly affected the entire aviation sector. The operation of the aviation sector during the pandemic period was affected by the administrative closure of flights for months, as well as the regulation banning flights to selected countries.MethodsThe study used the method of analyzing statistical data and reports on the aviation sector. The method of analyzing statistical data made it possible to compare data from the aviation sector on, among other things, the number of passengers carried, and the number of flights made.ResultsAs a result of the development of the Covid-19 pandemic, the aviation sector reduced the number of flights operated, which contributed to a decline in the number of passengers carried and heavy losses for the sector. During the pandemic period, the growth of airlines was sharply halted.ConclusionsAviation around the world operated for several months in a completely new and highly unpredictable reality. The crisis caused by the Covid-19 pandemic is the biggest crisis in aviation history. The sector needs to define clear rules and messages in crisis situations.

Impact of Blended Learning on NCLEX Scores and Subscores

The nursing workforce shortage is the biggest crisis that demands increased qualified licensed graduate nursing students. The shortage of licensed professional nurses has tremendously affected the quality of health care delivery. Subsequently, nursing schools are challenged to educate nursing students faster. Undergraduate nursing colleges have been challenged to educate more nurses faster to meet the increasing demands of qualified nurses in the workforce. Successful completion of the NCLEX exam is an entry requirement to practice as a registered nurse in the United States . The purpose of this quantitative, correlational research study is to compare the NCLEX score rates and sub-scores of psychosocial integrity and safety using data from multiple cohorts of the pre-licensure nursing program to evaluate the impact of the sudden transition from face-to-face (F2F) learning to a blended learning format. The study participants included students from the 2019 Spring and 2019 Fall cohorts who completed nursing in a F2F setup and 2020 Fall and 2021 Spring cohorts who completed nursing in a blended format. The pre-existing data of NCLEX scores and subcategory scores were obtained from two hundred and eighteen students enrolled in the F2F track, and two hundred and twenty-one students enrolled in the blended track of the nursing program. The pre-existing data obtained were coded separately in three sets using '0' for fail grade and '1' for pass grade to assess the correlation. The chi-square test of independence and Phi were employed to test the null hypothesis. The statistical analysis reported a significant difference in the NCLEX scores of the students, p < .001. Findings of the NCLEX safety and psychosocial subsection scores showed no ranked significant difference, p < .133 and p < .355. This study's results will help modify appropriate teaching-learning platforms to foster successful student learning outcomes and NCLEX success rates. Suggestions for future research include qualitative research to erase certain limitations, correlational studies including demographic factors, and a comparative study using a diverse, larger sample size. Additionally, as the global pandemic impacts this study, a follow-up study is recommended in the future to analyze NCLEX scores with sub-scores after the COVID pandemic. Keywords: Nurse education, NCLEX, COVID-19, Blended Learning, Exam scores. DOI: 10.7176/RHSS/13-6-02 Publication date: March 31 st 2023

Impact of COVID-19 and Online Streaming Services on the Movie Theater

Movie Theaters in India face a big crisis amid COVID-19, which leads to the shutdown of Theaters for more than five months. In the meantime, Online Streaming Services are expanding their business and revenue like never before. This scenario raises the very prominent questions (1) whether the movie theater business will survive this hard time and get back to normal growth and business once COVID-19 cases will reduce. The situation gets back to ‘old normal’. (2) Will Online Streaming services and Movie Theater business co-exist in the future, as Satellite TV and Movie Theater exist for many decades. Based on data from an empirical survey conducted among regular moviegoers, this paper questions the claims of the industry that the Movie Theater business is in danger due to the emergence of online streaming services. It has been observed that the increase in traffic on these online streaming services is mainly because of the lockdown situation, and once theater reopens and the COVID-19 health crisis went, people will get back to Theaters in a large number. Data from the reopening of Theaters in other countries are also showing the same result.

Financial and environmental resilience in times of crisis: A study of covid-19’s effects on Moroccan environmental companies

The analysis of Moroccan companies’ resilience is of extreme importance, especially in times of crisis. Covid-19 is an example that revealed the shortcomings and weaknesses of most Moroccan companies when it comes to crisis anticipation and management. In this paper, we have chosen to study the case of companies from two important industries in Morocco: agriculture and tourism. The aim is to investigate the level of preparation of these companies for the crisis, their reaction during the pandemic, and the lessons learned to be more resilient. The two case studies show a lack of preparation due to the sudden occurrence of the crisis, however, the impact was different between the two, due to the nature of the activity and the business size; one is a small local company (agriculture) and the other is the branch of a multinational one (hospitality). The study case results show that most of the companies’ functions were impacted (procurement, production, sales, etc.). These companies’ reaction was different as well, from acting on the inventories and managing the production (Agriculture Company) to optimizing human and financial resources and exploring swinging activities (Hospitality Company). Both got government support. The two companies agreed that the most important aspect of resilience is finance resilience which considers the wider definition of “generating value” that includes in addition to the turnover, the environment, the social and governance aspects (commonly known as ESG). According to the case study, for better resilience in the future, a greater awareness of the importance of financial & environmental resilience is key, and the use of performance metrics and indicators (KPIs) is the way, to allow close monitoring of the activity to be alarmed in advance and strategically anticipate big crises.

Democratic Reforms in the Political Space of Kazakhstan: Recent Developments and Challenges

Kazakhstan faced the biggest political crisis in early January 2022 in over three decades since itsindependence in 1991. The crisis began with protests over rising fuel prices which turned into widespreadunrest followed by the crackdown and finally returning back to normalcy. It is believed that for the KazakhPresident, Kassym-Jomart Tokayev, this has been the biggest crisis during his presidency, but since hehas been able to control the situation it also offers an opportunity, particularly in matters of democraticreforms in the country. The article focusses on the recent developments and challenges concerning thedemocratic reforms undertaken in Kazakhstan. The main aim and objective is to review the key initiativestowards democratic reforms, especially the political reforms taken by Kazakhstan both before and duringthe period of Tokayev’s presidency. This is so because both the founding President as well as the currentPresident have believed that democratic reforms in the political space of Kazakhstan is indispensableif this Central Asian country has to make a move into the World’s top 30 most developed nations. Themethods used in this research mainly include qualitative that helped understand diverse opinions andexperiences of Kazakhstan in its democratic reforms programmes and initiatives. The article concludesthat despite a series of measures aimed at implementing the democratic reforms, it is still too early topredict how the democratic reforms in the political space of Kazakhstan will take shape in the future. Key words: Political Reforms, Kazakhstan-2030” Strategy, Kazakhstan-2050, Five InstitutionalReforms and 100 Concrete Steps.

Testing big data in a big crisis: Nowcasting under Covid-19

During the Covid-19 pandemic, economists have struggled to obtain reliable economic predictions, with standard models becoming outdated and their forecasting performance deteriorating rapidly. This paper presents two novelties that could be adopted by forecasting institutions in unconventional times. The first innovation is the construction of an extensive data set for macroeconomic forecasting in Europe. We collect more than a thousand time series from conventional and unconventional sources, complementing traditional macroeconomic variables with timely big data indicators and assessing their added value at nowcasting. The second novelty consists of a methodology to merge an enormous amount of non-encompassing data with a large battery of classical and more sophisticated forecasting methods in a seamlessly dynamic Bayesian framework. Specifically, we introduce an innovative “selection prior” that is used not as a way to influence model outcomes, but as a selection device among competing models. By applying this methodology to the Covid-19 crisis, we show which variables are good predictors for nowcasting gross domestic product and draw lessons for dealing with possible future crises.

Political Violence and Instrumental Use of Religion in the Works of Carl Schmitt and Walter Benjamin

Walter Benjamin and Carl Schmitt were active in the interwar period, a very difficult time in the history of Germany. The issues of violence, war, and the role of religion in public affairs were of vast importance for both men. I want to show that, in relation to the issues of religion and political theology, both favored instrumentalizing religious concepts in the name of their own political ideas. Schmitt used Catholicism to establish the so-called concrete order, and Benjamin used Judaism to promote Marxist and anarchist ideas of liberation. That means they were more interested in earthly affairs than in having mystical religious experiences or exploring metaphysical concepts of God and the afterworld. I believe that the instrumental use of theology and religion in the works of Schmitt and Benjamin could indicate that theology was then and is now in a big crisis.

Changes in DMO’s Orientation and Tools to Support Organizations in the Era of the COVID-19 Pandemic

Following the COVID-19 pandemic, the tourism industry has been hit by the biggest crisis in its history. Its effects are visible throughout the tourism industry, including the management system (DMOs). The study aim is to the determine the changes that have been taking place in the operation of the destination management organizations (DMOs) in Poland as a result, including the usage of existing or expected organizational support tools. The study consisted of three stages: desk research, diagnostic survey, and qualitative and statistical analyses. Empirical data from all 16 regional DMOs in Poland were collected, including the use and effectiveness of the anti-crisis assistance programs, expectations towards the support tools, actions taken to mitigate the pandemic effects, and the changes in selected marketing activities and support strategies in the pre- and post-pandemic period. The study results indicated the insufficient availability of tools supporting the organizations’ activities during a pandemic and little use by the DMOs of most of the tools offered by the anti-crisis programs, alongside a moderate assessment of their effectiveness. The need to modify anti-crisis programs and/or expand them to include other forms of assistance available to the DMOs was identified. The proposed research tool can be implemented to assess the necessary actions taken during the crisis in other types of tourism organizations in various regions.

Constructive analysis on teaching architecture through face to face and online learning

A couple of decades now, online learning has gained some popularity among scholars to work across borders and use time efficiently. However, the advent of world pandemic that resulted in a big health crisis has spurred more interest to keep going with the online classes close the gap between students and their teachers.
 We present here a professional experience that we had in our architecture department during the Covid-19 period. This worth sharing experience has to explain the pedagogical content set in the training unit and will likewise emphasize the importance of “subject project workshop” used in the discipline of architecture.
 Our contribution in the light of this paper is to come up with suggestions likely to enhance the practice of teaching using modern resources.

Depression in pregnant and postpartum women during COVID-19 pandemic: systematic review and meta-analysis.

Coronavirus disease 2019 (COVID-19) emerged as a global pandemic in March 2020 and caused a big crisis, especially the health crisis. Pregnant and postpartum women experienced significant physical, social, and mental changes that put them at higher risk for several conditions during the pandemic. This study aimed to report the prevalence of depression in pregnant and postpartum women during the COVID-19 pandemic. Eligible studies were identified using several databases. Prevalence analysis was conducted using MedCalc ver. 19.5.1. This systematic review and meta-analysis was registered in PROSPERO on July 12, 2021 with registration number CRD42021266976. We included 54 studies with 95.326 participants. The overall prevalence of depression was 32.60% among pregnant and postpartum women during the COVID-19 pandemic. The rate was higher among pregnant women (31.49%) compared to postpartum women (27.64%). The prevalence of depression among pregnant and postpartum women increased during the COVID-19 pandemic.

Feature ranking and network analysis of global financial indices.

The feature ranking method of machine learning is applied to investigate the feature ranking and network properties of 21 world stock indices. The feature ranking is the probability of influence of each index on the target. The feature ranking matrix is determined by using the returns of indices on a certain day to predict the price returns of the next day using Random Forest and Gradient Boosting. We find that the North American indices influence others significantly during the global financial crisis, while during the European sovereign debt crisis, the significant indices are American and European. The US stock indices dominate the world stock market in most periods. The indices of two Asian countries (India and China) influence remarkably in some periods, which occurred due to the unrest state of these markets. The networks based on feature ranking are constructed by assigning a threshold at the mean of the feature ranking matrix. The global reaching centrality of the threshold network is found to increase significantly during the global financial crisis. Finally, we determine Shannon entropy from the probabilities of influence of indices on the target. The sharp drops of entropy are observed during big crises, which are due to the dominance of a few indices in these periods that can be used as a measure of the overall distribution of influences. Through this technique, we identify the indices that are influential in comparison to others, especially during crises, which can be useful to study the contagions of the global stock market.

Knowing Our True Self and Transforming Suffering toward Peace and Love: Embodying the Wisdom of the Heart Sutra and the Diamond Sutra

The biggest crisis that we are in nowadays is existential, which is the state of not knowing our true natures or our true selves; hence, we suffer from deep anxiety and we fail to find safety and a way to ground ourselves. In this article, we share our practical experiences of encountering and practicing the teachings of two important Buddhist scriptures: the Heart Sutra and the Diamond Sutra. We show how both sutras, and especially their teachings on emptiness, allow us to remove our attachment to a sense of a separate self, which deepens our understanding about life, and transforms suffering toward peace and love. We further demonstrate the importance of meditation, contemplative chanting and reading, and experimentation with Buddhist teachings as pathways towards understanding our true natures. In sum, both sutras help us to go beyond the materialistic, capitalistic, narrow vision of who we are and to access the higher dimension of our existence, which allows us to discover our cosmic selves in the ultimate reality. It is through experiencing one’s true self that one gains a greater capacity to seek social transformation in times of crisis.
