A total of 40,359 tweets related to COVID-19 vaccination were collected between January 2021 and March 2021. Misinformation was detected using multiple predictive machine learning models. Latent Dirichlet Allocation (LDA) topic model was used to identify dominant topics in COVID-19 vaccine misinformation. Sentiment orientation of misinformation was analyzed using a lexicon-based approach. An independent-samples t-test was performed to compare the number of replies, retweets, and likes of misinformation with different sentiment orientations. Based on the data sample, the results show that COVID-19 vaccine misinformation included 21 major topics. Across all misinformation topics, the average number of replies, retweets, and likes of tweets with negative sentiment was 2.26, 2.68, and 3.29 times higher, respectively, than those with positive sentiment.","PeriodicalId":42590,"journal":{"name":"International Journal of Business Analytics","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44548556","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We can take place due to many types of motives such as samples mishandling, unable to collect an observation, measurement errors, aberrant value deleted, or merely be short of study. The nourishment area is not an exemption to the difficulty of data missing. Most frequently, this difficulty is determined by manipulative means or medians from the existing datasets which need improvements. The paper proposed hybrid schemes of MICE and ANN known as extended ANN to search and analyze the missing values and perform imputations in the given dataset. The proposed mechanism is efficiently able to analyze the blank entries and fill them with proper examining their neighboring records in order to improve the accuracy of the dataset. In order to validate the proposed scheme, the extended ANN is further compared against various recent algorithms or mechanisms to analyze the efficiency as well as the accuracy of the results.","PeriodicalId":42590,"journal":{"name":"International Journal of Business Analytics","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42335116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In other words, user profiles based on user interest within the healthcare domain are constructed from the kind of journal papers read by the users. Multiple user profiles are constructed for each user based on different categories of papers read by the users. The proposed approach goes to the granular level of extrinsic and intrinsic relationship between terms and clusters highly semantically related relevant domain terms where each cluster represents a user interest area. The semantic analysis of terms is done starting from co-occurrence analysis to extract the intra-couplings between terms and then the inter-couplings are extracted from the intra-couplings and then finally clusters of highly related terms are formed. The experiments showed improved precision for the proposed approach as compared to the state-of-the-art technique with a mean reciprocal rank of 0.76.","PeriodicalId":42590,"journal":{"name":"International Journal of Business Analytics","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41834435","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The most important parameters of fetal heart is the baseline upon which the other parameters viz. acceleration, deceleration and variability depend. Accurate classification of the baseline into either normal, bradycardia or tachycardia is thus important to assess the fetal-health. Since visual estimation has its limitations, the authors use various Machine Learning Algorithms to classify the baseline. 110 CTG traces from CTU-UHB dataset, were divided into three subsets using stratified sampling to ensure that the sample is the accurate depiction of the population. The results were analyzed using various statistical methods and compared with the visual estimation by three obstetricians. FURIA provided greatest accuracy of 98.11%.

NCS involves the feedback control loop system wherein the control components such as actuators and sensors are controlled and allowed to share their feedback over real time network with distributed users spread geographically. The performance and surgical complications majorly depend upon time delay, packet dropout and jitter induced in the system. The delay of data packet to the receiving side not only causes instability but also affect the performance of the system. In this article, author designed and simulate the functionality of a model-based Smith predictive controller. The model and randomized error estimations are employed through Markov approach and Kalman techniques. The simulation results show a delay of 49.926ms from master controller to slave controller and 79.497ms of delay from sensor to controller results to a total delay of 129.423ms. This reduced delay improve the surgical accuracy and eliminate the risk factors to criticality of patients’ health.","PeriodicalId":42590,"journal":{"name":"International Journal of Business Analytics","volume":"1 1","pages":""},"PeriodicalIF":1.1,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70451284","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At the same time state attitude towards violence and transformation of warfare has been changing as well. Two diff erent approaches to the history of the private security market’ rise unveil the fact, that, in one way or another, the originators of the private security services were associated with the defense industry and armed forces. Non-state security actors look back on a history, that stretches to the middle and the second half of the 20th century – the period of national liberation movements across the world. Meanwhile, the 90-s of the 20th century marked the fast growth in the number of PMSCs and in the development and enlargement of the private security services’ market. Its growth is ongoing to date with gaining more new states that are interested in utilizing its capacity as an instrument of politics. Against the backdrop of the world political processes the private security market experienced technological growth and enhancement. Together with that, both the normative regulation and the approaches of the international community to the phenomenon of private military and security companies have been evolving and changing. Despite its functionality, fl exibility and technological advantages, the market of private security can challenge human rights as well as bare responsibility for the facts of corruption and improper fulfi llment of contractual obligations. Still the episodes of revealed grieve violations rarely reach courts, with infrequent cases of sentencing the perpetrators to punishment. These and other problems occurring in the private security industry require close attention by the states and international community, which has been making eff orts for elaboration of the applicable normative mechanisms to regulate private military and security activity for more than fi fteen years.","PeriodicalId":42590,"journal":{"name":"International Journal of Business Analytics","volume":"156 6 1","pages":""},"PeriodicalIF":1.1,"publicationDate":"2022-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83208349","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Deriglazova","doi":"10.46272/2587-8476-2022-13-2-23-42","DOIUrl":"https://doi.org/10.46272/2587-8476-2022-13-2-23-42","url":null,"abstract":"The article discusses the features of armed confl icts at the beginning of the 21st century through the prism of the theory of asymmetric confl ict. Within the framework of the theory, basic and accompanying asymmetries are distinguished, which determine the reasons for the political, rather than military, defeat of developed countries in wars against relatively weak opponents. At the beginning of the 21st century most of the armed confl icts have pronounced signs of multiple asymmetries that aff ect the course and outcome of confl icts. On the basis of the theory, several important aspects can be distinguished that should be taken into account by the military and politicians when planning and conducting military operations. Among them: the legitimacy of military operations from the point of view of international law, neutralization of anti-war sentiments, minimization of losses of military personnel, ensuring the safety of the population in the war zone. Foreign analytics is characterized by a focus on the reasons for the failures of the United States and other Western states in military operations in Afghanistan, Iraq, Libya, and Syria. Among the reasons for the failures are a lack of understanding of the culture and characteristics of the countries where hostilities are conducted, the regime of occupation, and attempts at nation-building. Some foreign experts note that the Russian Federation is much more successful in participating in asymmetric confl icts of the 21st century. Among Russian military experts, there is a noticeable interest in developing an “asymmetric war” strategy in the framework of the geopolitical confrontation with the countries of the West. The tendency to develop non-contact methods of warfare and the involvement of private military companies to neutralize anti-war sentiments and minimize losses of military personnel has a universal character. At the same time, the problem of non-selectivity of such methods of warfare and their compliance with international law is becoming more and more acute. The theory of asymmetric confl ict is a theory of international relations, which main assumptions are are useful for politicians and the military to take into account in the process of deciding on the start of hostilities and the possibility of achieving political goals by military means, and not just for fi nding victorious strategies in asymmetric confl icts.","PeriodicalId":42590,"journal":{"name":"International Journal of Business Analytics","volume":"42 1","pages":""},"PeriodicalIF":1.1,"publicationDate":"2022-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81420717","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
