The media influence politics by providing intelligence and arena for political statements. Therefore, the danger of spreading false information and deliberate disinformation can have serious consequences. It is impossible to accuse specific media outlets of unfair coverage, but one cannot fail to note the existing resonance in media reports from different countries. Interpretations of the same events are radically different, while a journalist must rely on facts. The world is faced with the problem of global misunderstanding and information discord. Modern international broadcasting plays an important role in shaping the picture of the event for the world community. It is impossible to deny that the information agenda of many foreign broadcast media depends to some extent on a number of reasons: nationality, foreign policy of his state, profitability. Otherwise, the global media would not contradict each other. We want to track how modern foreign broadcasting builds its agenda and what principles it is guided by.

Social Media Platforms

Fake or false information on social media platforms is a significant challenge that leads to deliberately misleading users due to the inclusion of rumors, propaganda, or deceptive information about a person, organization, or service. Twitter is one of the most widely used social media platforms, especially in the Arab region, where the number of users is steadily increasing, accompanied by an increase in the rate of fake news. This drew the attention of researchers to provide a safe online environment free of misleading information. This paper aims to propose a smart classification model for the early detection of fake news in Arabic tweets utilizing Natural Language Processing (NLP) techniques, Machine Learning (ML) models, and Harris Hawks Optimizer (HHO) as a wrapper-based feature selection approach. Arabic Twitter corpus composed of 1862 previously annotated tweets was utilized by this research to assess the efficiency of the proposed model. The Bag of Words (BoW) model is utilized using different term-weighting schemes for feature extraction. Eight well-known learning algorithms are investigated with varying combinations of features, including user-profile, content-based, and words-features. Reported results showed that the Logistic Regression (LR) with Term Frequency-Inverse Document Frequency (TF-IDF) model scores the best rank. Moreover, feature selection based on the binary HHO algorithm plays a vital role in reducing dimensionality, thereby enhancing the learning model’s performance for fake news detection. Interestingly, the proposed BHHO-LR model can yield a better enhancement of 5% compared with previous works on the same dataset.

Background: The number of contingent valuation (CV) studies in dental medicine using willingness-to-pay (WTP) methodology has substantially increased in recent years. Missing values due to absent information (i.e., missingness) or false information (i.e., protest zeros) are a common problem in WTP studies. The objective of this study is to evaluate the prevalence of missing values in CV studies in dental medicine, to assess how these have been dealt with, and to suggest recommendations for future research. Methods: We systematically searched electronic databases (MEDLINE, Web of Science, Cochrane Library, PROSPERO) on 8 June 2021, and hand-searched references of selected reviews. CV studies in clinical dentistry using WTP for valuing a good or service were included. Results: We included 49 WTP studies in our review. Out of these, 19 (38.8%) reported missing values due to absent information, and 28 (57.1%) reported zero values (i.e., WTP valued at zero). Zero values were further classified into true zeros (i.e., representing the underlying preference of the respondent) or protest zeros (i.e., false information as a protest behavior) in only 9 studies. Most studies used a complete case analysis to address missingness while only one study used multiple imputation. Conclusions: There is uncertainty in the dental literature on how to address missing values and zero values in CV studies. Zero values need to be classified as true zeros versus protest zeros with follow-up questions after the WTP elicitation procedure, and then need to be handled differently. Advanced statistical methods are available to address both missing values due to missingness and due to protest zeros but these are currently underused in dental medicine. Failing to appropriately address missing values in CV studies may lead to biased WTP estimates of dental interventions.

IntroductionEpiCore draws on the knowledge of a global community of human,animal, and environmental health professionals to verify informationon disease outbreaks in their geographic regions. By using innovativesurveillance techniques and crowdsourcing these experts, EpiCoreenables faster global outbreak detection, verification, and reporting.MethodsThrough a secure online platform, members are able to easily andquickly provide local information to expedite outbreak verification.EpiCore volunteer applications are vetted to ensure that they possessthe public health and epidemiologic expertise necessary to contributeto the platform.ResultsEpiCore currently has over 1600 members that span 135 countries.During the first 8 months of EpiCore’s launch, 172 requests forinformation to volunteers have been posted with an average responserate of over 80%.ConclusionsWith its geographical distribution of members and high responserate, EpiCore is poised to enable the world to verify potential outbreaksignals faster. By improving situational awareness, de-escalatingrumors or false information, and corroborating using other existingsources, EpiCore is able to reduce the signal to noise ratio in diseasesurveillance. Hence, by detecting and verifying outbreaks faster,health officials can generate early responses that can curb epidemicsand save lives.

The article analyzes the main measures of the Soviet regime to discredit the dissident Valentyn Moroz in the 1970s and early 1980s. This problem has not been studied in Ukrainian historiography yet. The basis of sources is previously classified documents of the Sectoral State Archive of the Security Service of Ukraine (SSA SSU), as well as materials of the Central State Archive of Public Associations of Ukraine (CSAPA), the Soviet press, memoirs of participants of the dissident movement. The chronological framework, stages and tasks of the discrediting campaign are singled out. Among its methods there is the distribution of false information about the dissident through the Ukrainian and foreign press, the initiation of conflicts with the participation of V. Moroz in the Mordovian colonies and in emigration, diplomatic pressure on the governments of the West. The author concludes that the KGB campaign has become one of the most important factors that led to a fall in the reputation of V. Moroz at the turn of the 1970s-1980s. Keywords: Valentyn Moroz, Ukrainian dissident movement, Soviet regime, discrediting campaign, disinformation, Ukrainian diaspora
