In the Eye of the Storm: Social Media and Crisis Management
Authors: Banyongen Serge
Published: May 2023

Social media, also called Web 2.0, is a generic term used to talk about applications that allow users to create, manipulate, and disseminate content as much as possible in real time. These applications allow for several possibilities that range from involvement to participation, communication, and collaboration of users. They allow everyone with minimal access to the Internet to publish, share, review, comment, and post items, such as mentions, comments, information, videos, and photos. In a crisis, social media becomes a double-edged sword. It can play an essential role during the prodromal, acute, chronic, and resolution phases of natural disasters and human-made crises. Social media can also be at the origin of the crisis or the reason for its amplification. Social media facilitates an increase of interactions between main actors at the center of a crisis. This chapter combines social media content analysis (opinion detection and sentiment analysis) with network analysis (ego network analysis) and nodes centrality assessment to critically evaluate how social media affects the crisis management process.

Authors: Tunde Olorunsogo Samuel , Adenike Adejumo Bolanle
Published: May 2023

Flakes are one of the most popular ready-to-eat breakfast cereals meals. Most traditional instant breakfast meals are from mono-cereals. This work aims to develop, characterize and optimize value-added instant cereal breakfast flakes using flours of rice, sorghum, and soybean. A three-component constrained optimal (custom) mixture experimental design was employed for the formulation. The formulation design constraints were: rice flour (30%–35%), sorghum flour (20%–25%), and soybean flour (5%–10%). Other ingredients were water (19%), sugar (8%), malt (2%), egg (3%), sweet potato (3%), ginger (2%) and moringa seed powder (3%). The formulated samples were analysed and evaluated based on standard procedures for quality characteristics. Numerical optimization gave the optimal product\'s overall desirability index of 0.519 obtained from 31.9 % rice flour, 22% sorghum flour, and 6.05% soybean flour; with quality properties as follows: 3.67% moisture content, 3.18% fat content, 3.08% ash content, 1.44% crude fibre, 30.0% crude protein, 58.6% nitrogen-free extract, 384 kcal energy value, and 7.28 overall acceptability. The result of the study showed that the nutritional qualities of cereal flakes can be improved through food-to-food composite formulations, employing numerical optimization technique.
Formulation of Edible Bigel with Potential to Trans-Fat Replacement in Food Products
Authors: Mishra Sunita , Firdaus M.A.
Published: May 2023

A new issue for the scientific community is to find efficient replacements for unhealthy fat without damaging the organoleptic qualities of the food product in light of growing concerns about the consumption of harmful trans fats in the diet. Bigel is supposedly a novel structured fat system utilised for industrial purposes due to their nutritional advantages, one of numerous solutions intended to replace trans fats in food. These have a lot of potential in the food industry, and are composed of an aqueous phase known as a hydrogel and an organic phase known as an organogel or oleogel. A gel known as an oleogel has oil as its liquid component. Oleogelators, which aid in the development of gels, frequently have low molecular weight, whereas typical hydrogelators have large molecular weight since they are polymeric. A hydrogel is a gel in which water serves as the immobilised phase. Therefore, a bigel is a biphasic system made up of an oleogel and a hydrogel. This chapter will concentrate on the various bigel formulation techniques and chemistry, as well as their latest food uses, and other industries that fit their requirements.
Federated Learning Hyper-Parameter Tuning for Edge Computing
Authors: Zhang Xueying , Fu Lei , Zhang Huanle , Liu Xin
Published: May 2023

Edge computing is widely recognized as a crucial technology for the upcoming generation of communication networks and has garnered significant interest from both industry and academia. Compared to other offloading models like cloud computing, it provides faster data processing capabilities, enhanced security measures, and lower costs by leveraging the proximity of the edge servers to the end devices. This helps mitigate the privacy concerns associated with data transfer in edge computing, by reducing the distance between the data source and the server. Raw data in typical edge computing scenarios still need to be sent to the edge server, leading to data leakage and privacy breaches. Federated Learning (FL) is a distributed model training paradigm that preserves end devices’ data privacy. Therefore, it is crucial to incorporate FL into edge computing to protect data privacy. However, the high training overhead of FL makes it impractical for edge computing. In this study, we propose to facilitate the integration of FL and edge computing by optimizing FL hyper-parameters, which can significantly reduce FL’s training overhead and make it more affordable for edge computing.
On-Line Monitoring and Intelligent Diagnosis Technology of Rail Transit Ventilation System
Authors: Song Yongxing
Published: May 2023

With the rapid development of economy and urbanization, subway has gradually become the main pillar of urban development. The ventilation system is the key guarantee of air quality in rail transit, and its condition monitoring and intelligent diagnosis are very important. The core problems of the complete set of a ventilation system required by the subway station have not been completely solved. The ventilation system includes the ventilator and additional equipment. The level of informatization and intelligence of the ventilation system and ventilator is not very high, and they have not yet been fully formed into an integrated diagnostic system. In view of the above two core issues, several scientific issues need to be tackled. This chapter studies the online monitoring and intelligent diagnosis mechanism of key equipment in the subway ventilation system. This mainly includes (1) modulation model of acoustic vibration signal; (2) noise reduction technology and feature extraction method; and (3) cases of multi-type typical fault identification fan equipment based on modulation model. Typical fault features were extracted respectively, which verified the effectiveness of the signal demodulation method for the diagnosis of rail transit ventilation systems.
Crystal Facet Engineering of TiO2 from Theory to Application
Authors: Dudziak Szymon , Kowalkińska Marta , Zielińska-Jurek Anna
Published: May 2023

Recently, the surface structure effect on photocatalytic activity has gathered increasing attention due to its reported influence on the charge carrier trapping and separation. Detailed control over the surface structure can be achieved by exposing the specific crystal facets. As a result, the photogenerated electrons and holes can be effectively separated between the different facets of semiconductor crystals. TiO2 is the most studied photocatalyst, with the particles exposing {0 0 1}, {1 0 0}, {1 0 1}, {1 1 0}, {1 1 1}, and {1 0 5} crystal facets. The performed studies have shown that the efficiency of the photocatalytic process strongly depends on the nature of the crystal facet exposed at the photocatalyst surface. In this regard, this chapter focuses on the comparison of possible surface-related parameters and photocatalytic activity of anatase, rutile, and brookite polymorphs with exposed different crystal facets. Particularly, computational data on their different possible surface structures are summarized, focusing on the geometry, energy, and possible reconstructions. This is followed by the general description of the hypothetical Wulff constructions and existing stabilization/synthesis strategies. Such an approach could help to further design, simulate, and optimize photocatalyst surface for efficient photoreduction and photooxidation processes.

Authors: Mokhtari Mohammad , Faridi Parvaneh , Masoodi Mehdi , Mehran Ahmadi Seyed
Published: May 2023

Natural hazards have become an increasingly prevalent threat to the world, with the frequency of recorded disasters rising in the recent years. Analyzing global data on natural hazards, identifying the most common and deadly events, and prioritizing decision-making on safe constructions, settlements, and factories are crucial to respond effectively to this trend. Using the EM-DAT database, this study examined primary natural hazards worldwide from 1900 to 2022, including earthquakes, volcanic eruptions, landslides, floods, droughts, wildfires, storms, and extreme temperatures. Statistical data show that storms have the highest frequency of occurrence (38%), droughts are the deadliest (53%), floods affect the most people (50%), and storms cause the most economic losses (41%). Asia has experienced the highest frequency, most deaths, and most total affected people due to natural hazards, followed by North America and Africa, respectively. North America has also seen the highest economic losses, followed by Asia and Europe. The study emphasizes the importance of databases like EM-DAT in advancing our knowledge of natural hazards worldwide, and supporting informed decision-making in risk assessment, disaster management, and mitigation efforts.
Anti-Tumor Drug Resistance and Modern Oncologic Pharmaco-Therapy: RNA and DNA Methylation, Mechanisms and Histone Modification, Epigenetic Regulation and Targeting Epigenetic Modifiers in Contemporary Cancer Therapy
Authors: S. Haidar Ziyad
Published: May 2023

Metastasis, the spread of cancer cells from the primary tumor to the surrounding tissues and to distant organs, is one (and perhaps the primary) of the major causes of cancer-related death (or cancer morbidity and mortality). Indeed, it is estimated that metastasis is responsible for about 90% of cancer deaths. The major factors contributing to the metastasis of cancer cells are epithelial-mesenchymal transition (EMT) and cancer stem cells (CSCs). Herein, the cancer cells must detach from the primary tumor, intravasate into the circulatory and lymphatic systems, evade immune attack, extravasate at distant capillary beds, and invade and proliferate in distant organs. Accruing evidence suggests that the malfunction of epigenetic regulation in the functioning of a gene is directly related to the generation of tumors and cancer. Henceforth, the potential and capacity to change or re-program the epigenetic landscape within the epigenome of cancer is possibly the most promising and pursued targeted therapy, nowadays. Such would lead to reversing drug resistance and so, new therapeutic modalities. Indeed, contemporary oncologic pharmaco-therapy for cancer has and continues to undergo remarkable changes; especially lately, in terms of the introduction of effective cancer-specific molecular-targeted therapeutic agents. This introductory chapter to the book titled: “DNA Replication – Mechanisms, Epigenetics, and Gene Therapy Applications” discusses DNA and RNA methylation, the mechanisms of histone modification, and presents a variety of epigenetic modifications which can lead to anti-tumor drug resistance. It also explores how targeting epigenetic modifiers can reverse drug resistance.
Investigating an online rater training program: product and process
Authors:   The University of Auckland, Erlam Rosemary , Randow Janet von ,   The University of Auckland, Read John ,   The University of Auckland
Published: May 2023

The Diagnostic English Language Needs Assessment (DELNA) programme at the University of Auckland has traditionally offered face-to-face training to both new raters and to experienced raters of writing who need to undergo refresher training in order to increase inter-rater and intra-rater reliability. However, for reasons of practicality and convenience, an online program to offer refresher training for experienced raters was developed and revised after trialling in 2003-04 (Elder, Barkhuizen, Knoch & von Randow, 2007). The study reported on in this paper arose out of the need to establish the validity of using this online DELNA program to train new raters (i.e., novice raters). Rater-training outcomes were investigated through the analysis of quantitative data. However, there was also a focus on the ‘process of rating’ using qualitative data, that is, think-aloud protocol, to identify rating behaviours associated with more vs. less reliable ratings. Results suggest that this program has potential to train novice raters to rate reliably but that future research needs to investigate more rigorously the impact of a program like this one on subsequent rating. Nvivo analysis of the think-aloud protocols highlighted key aspects of the rating behaviours of more and less reliable raters.
​Defining assessment standards for a new national tertiary-level qualification
Authors:   The University of Auckland, Read John
Published: May 2023

In this era of public accountability, defining levels of performance for assessment purposes has become a major consideration for educational institutions. It was certainly true of the development by the national qualifications authority of the New Zealand Certificates of English Language (NZCEL), a five-level sequence of awards for learners of English as an additional language at the post-secondary level implemented in 2014. The process of defining the five levels involved benchmarking of standards both nationally and internationally, particularly in relation to the Common European Framework of Reference (CEFR). This paper presents an outsider’s view of the definition of standards for the NZCEL, based on information provided by key participants at the national and local levels. The process has involved taking account of not only the CEFR but also the New Zealand Qualifications Framework (NZQF) and the band score levels of the International English Language Testing System (IELTS). The paper focuses in particular on the issue of establishing the equivalence of NZCEL 4 (Academic) to other recognised measures of English language proficiency as an admission requirement to undergraduate study for international students. The benchmarking process was both multi-faceted and open-ended, in that several issues remain unresolved as implementation of programmes leading to the NZCEL 4 (Academic) has proceeded. At the time of writing, the NZCEL qualifications are scheduled for a formal review and the paper concludes with a discussion of the issues that ideally should be addressed in evaluating the qualification to date.

The Diagnostic English Language Tracking Assessment (DELTA) writing project: a case for post-entry assessment policies and practices in Hong Kong universities
Authors:   City University of Hong Kong, Lockwood Jane
Published: May 2023

This article describes undergraduate English language support in the context of universities in Hong Kong, with reference to early academic writing needs and support. It focuses specifically on the writing needs of post-entry year 1 students as reported in a series of Hong Kong based studies, and on the recent outcomes of a project funded by an Education Research Grant (ERG): The Diagnostic English Language Tracking Assessment (DELTA) – The Writing Assessment. These studies have revealed that many undergraduate students, whilst obtaining university mandated minimum entry levels for English, are challenged by the demands of academic writing when studying in Hong Kong EMI (English medium instruction) universities. This article reports on this situation and positions DELTA as a desirable post-entry assessment instrument, arguing that it is a critical part of a multilayered approach to addressing the poor English language levels of novice Hong Kong undergraduate students.

The Social Vulnerabilities of Science and the Covid-19 Pandemic Crisis
Authors: Stoenescu Constantin ,   Polish Academy of Sciences
Published: May 2023

According to the traditional image of science, if its achievements are reliable, then they will be communicated successfully and the public will trust in their applicability to solve practical problems. The new perspective on science as “socially robust knowledge” (Gibbons, 1999) is based on two other necessary conditions of knowledge production, namely, transparency and public participation. But the recent Covid-19 pandemic crisis has shown that the institutional weaknesses of the relationship between science and society generates an equally endemic mistrust. Should we go back to “heroic science” and the ‘“magic of science” to regain trust? Or the pandemic crisis just highlighted that the death of expertise (Nichols, 2017) is inevitable in the public space?
Political Limit of Neoliberal Democracy: The Strategy of Inequality
Authors: Zhurbina Irina ,   Polish Academy of Sciences
Published: May 2023

The paper studies political consequences of the establishment of neoliberal democ-racy, which means the onset of a post-political state of the world. It is demonstrated that at the “end of politics,” the democratic principle of equal rights turns into its opposite—a radical inequality between transnational elites, personifying the power of “pure” capital, and the local population, representing the idea of “pure” life. Neoliberal democracy is studied as a limit concept, which shows the exhaustion of the democratic principle of equality. The paper shows that the return to democracy as the principle of equality becomes the driving ambition of modern politics of activism as a subjective process, unfolding in places where a situation of radical inequality arises.
Racism as a Face of Modern Democracy
Authors: Churashova Ekaterina ,   Polish Academy of Sciences
Published: May 2023

The paper aims at studying the problem of dominance of some states over others in international communication. The hypothesis of the study is the idea that one of the reasons of the inequality of states is the hegemony of democracy. We can designate this amazing phenomenon as “political racism.” Democracy has defined the dominant polit-ical race in the last decade. States that do not belong to this “higher” race are recognized as inferior, dangerous for the countries of the “democratic race.” The danger of political racism lies in the transition to “fascist democracy.”
Contemporary Migration as a Repercussion of Economic Globalization and Democratic Processes, with Reference to Serbia and the Balkans
Authors: Ðelić Anastazija Tanja ,   Polish Academy of Sciences
Published: May 2023

The central problem in the present globalization and democratic processes is the constant increase of socio-economic inequalities. This involves modern migrations with overall risks. As a social phenomenon, migration has been presented since ancient times. It occurs in all societies and due to historical, social and cultural differences, the reaction of individuals and communities to migration can be very different. In the contemporary society that emphasizes mobility and information flow, migrations have become an integral part of life and society. Moreover, their scope and patterns become more and more complex. Given the recent increase in irregular migration to Europe, there is growing interest in developing new ways to collect and analyse data on irregular migration. Migration is today more than ever at the centre of global attention. The main goal of internationational organizations in this field is to harness the development potential of migration for individual migrants and societies. The Balkans region has witnessed a sharp increase in the numbers of mixed migration flows arriving in or transiting through its territory, along the so-called Balkan route. My country, i.e. Serbia, is facing a series of political, economic, social and cultural challenges, which this paper examines, explaining why the state still has a high emigration and low immigration potential, as well as to what extent the return to Serbia today is a complex option. In addition to the high numbers, the mixed composition of these flows adds complexity to the task of addressing them effectively and in line with international commitments and standards. This study focuses on the relations between international organizations, migrations and national interests of countries. The author determines that migrations are, to some extent, a challenge for the Balkan region, not only in terms of an increased danger of extremism, but also because of the possible outbreak of regional conflicts.
Thomism and the Neurological Criteria for Death
Authors: Tran Phil ,   The National Catholic Bioethics Center
Published: May 2023

One of the most important questions when determining when it is appropriate to procure organs from a deceased organ donor is what can be considered death. Currently, there is significant debate over whether brain death is an appropriate method of declaring an individual dead. As it would be illicit to cause the death of a patient by removing their organs, a medical professional must be certain that a brain dead patient is, in fact, dead before the procedure. In this paper, the author makes the case in support of considering brain death actual death.

Predictive Archaeological Modeling with MaxEnt (Late Roman Settlements in The Upper Don Basin Case)
Authors:   Voronezh State University, Sarychev Dmitry V. , Zemtsov Grigory L. ,   Lipetsk State Pedagogical University
Published: May 2023

The paper is devoted to an archaeological predictive modeling technique with GIS and machine learning based on maximal entropy algorithm (MaxEnt). Archaeological sites of the late roman time presented by settlements of Kashirka-Sedelok type (mid-3rd — early 4th century AD) in the Upper Don basin were the modeling objects. We found out that there are 169 known sites of such type in the study region, and collected all available information on their locations into a geodatabase including our own field survey data. The coordinates of these sites split into training and testing subsets served for developing a predictive model with MaxEnt. Environmental GIS-layers based on a digital elevation model and thematic maps were the model predictors. We made such predictors to reflect the paleogeography of the Upper Don basin in the study time period by choosing relatively stable landscape features of relief, bedrock, climate, hydrography and soils of the area. The trained model analyzed through more than 7 million cells of 90x90 m with overall area of 59 400 sq. km to identify potentially suitable areas for the Kashirka-Sedelok settlements and found 29 860 ha the most suitable areas (less than 1 % of the study area) as the result. The efficiency of the conducted modeling, evaluated on the testing sites, is high based on metrics of receiver operating characteristic (AUC = 0,915) and Kvamme’s Gain (KG = 0,97). The results of modeling serve as an agenda for the upcoming archaeological surveys in the region.
Past and present of the abolished settlements in the Republic of Karelia
Authors:   Saint-Petersburg State University of Economics, Balabeikina Olga A. , Korobushchenko Valeria Yu. ,   Saint-Petersburg State University of Economics
Published: May 2023

History of the settlements of the Republic of Karelia, abolished in the period of late 1950s — early 2020s, is examined in the article. Based on content analysis and information from photographic documents posted in public, the current state of the territories of abolished rural settlements is described. The authors focus on a specific category of abolished settlements of the Republic of Karelia, whose population in the pre-revolutionary period was more than 150 people. Thus, such settlements as Keret, Kakkarovo, Vashakovo, Lagilamba, Signavolok and Lyadinskaya were considered in the article. Out of these Keret had the longest history and the biggest economic importance in the past, therefore it’s examined with the highest degree of detail. In general, abolished settlements of the named category have either retained their residential function, being absorbed by neighboring villages as a part of their planning structure, or become abandoned territories with heavily ruined residential buildings. In addition, abolished settlements have the tendency to become more and more involved in the recreation economy; the most promising areas are sports, kayaking, expeditionary and religious tourism. Considering the popularity of recreation in quite distant places, the demand for guest houses equipped on the basis of restored historical Pomor houses is likely to increase.

A Thematic Analysis of the use of Social Media Marketing in Higher Education
Authors: Benedict Liza , Leach Lesley F. , Winn Pam , Baker Credence
Published: May 2023

A review of the empirical, peer-reviewed literature related to marketing in higher education was conducted to examine the use and effectiveness of social media in higher education institutions. Results from twelve peer-reviewed, empirical studies were thematically analyzed. Findings were outlined in a thematic map with three emergent themes: (a) why social media marketing is used in higher education, (b) the purposes for which social media marketing is being used in higher education, and (c) the effectiveness of the use of social media marketing in higher education. Results suggested prospective students still rely on the traditional forms of marketing, such as institutional web and print materials, although there is some evidence that social media is gaining prominence in their decision-making process. In summary, findings imply university marketers should strategically plan, including assessing student preference regarding social media communication, in order to embed social media marketing as an institution-wide tactic taking into account the collection of measurable analytics on the effectiveness of the effort.
Journalists Taking the Offensive: Paradigm Repair and the Daily Ethics Scandal
Authors: McCaffrey Raymond
Published: May 2023

This study examined how journalists defended their profession as a stream of journalistic ethics breaches have spawned an onslaught of criticism online and via social media. A textual analysis of more than 500 stories about journalism ethics violations in 2014 revealed that journalists are employing a broad-based discursive strategy reflective of so-called “second-order paradigm repair.” When confronted with a major scandal such as the uproar involving the disputed Rolling Stone story about an alleged gang rape at the University of Virginia, journalists can still respond in a manner consistent with traditional paradigm repair, which involves more elaborate strategies such as shifting the blame to rogue journalists and emphasizing corrective action by media outlets to reaffirm core values such as objectivity. Yet in response to the more commonplace journalism scandals, journalists have employed second-order paradigm repair, which allows members of the media to advance a competing narrative that enhances and supports a sense of professional identity. This identity is one in which journalists are portrayed as defending the profession from outside threats, such as challenges to press freedoms by governments entities as well as ethical compromises by media owners pandering to advertisers and business interests. This narrative can serve to deflect criticism of journalists, as seen in stories about media coverage of racially-charged protests in Ferguson, MO, which focused on challenges to press freedoms instead of criticism about the insensitivity of reporters. At the same time, journalists have utilized a quick-strike response to ethical lapses that often shifts the blame to the disruptive forces of new technology.
#NotAllBaptismByFire: The state of social media training at student-run communication organizations
Authors: Maben Sarah , Colley Kay
Published: May 2023

Advisers (n=112) and student leaders (n=31) from North American collegiate student-run communication organizations reported on their social media training. Through a snowball sample, advisers and student leaders from campus newspapers, magazines, radio and TV stations, advertising/public relations firms filled out an online questionnaire. As a state of social media training study, these findings provide a picture of student-run communication organizations today and their training experiences with social media. A little more than half included social media in their training, which focused on professionalism and content creation. Likewise, content creation and professionalism were the topics advisers reported students needed most. Advisers agreed or strongly agreed that students needed social media training and that social media usage is an integral part of their organizations. Researchers provide recommendations for future study and directions for training improvement.

Бұл білім алушыларды тілді шынайы өмірде қолдануға бейімдейді. Яғни, қатысымдық жаттығулар үйретілген лексикалық бірліктер мен грамматикалық формаларды есте сақтау, тілдесім барысында оларды пайдалану дағдыларын қалыптастыруды ғана емес, сонымен бірге қарым-қатынаста, яғни сөйлеу актілерін жүзеге асыруда тіл үйренушінің тілдік тәжірибесін қалыптастыруда маңызды болып табылатын тілді қолдану дағдысын қалыптастыруға және оны дамытуға негіз болады. Сондықтан мақалада қатысымдық жаттығулардың түрлері сипатталды мен тиімділігі дәлелденді. Қатысымдық жаттығуларды қолдану білім алушылардың қатысымдық дағдыларын дамытуға, тіл үйренуге деген ынтасын, қызығушылығын арттыруға ықпал ететінін зерттеу жұмысымыздың нәтижесі көрсетті. Қатысымдық жаттығуларының ең тиімді түрлері рөлдік ойындар, пікірталас және топтық тапсырмалар екені анықталды. Дегенмен, жақсы нәтижеге жету үшін қатысымдық жаттығуларды грамматикалық жаттығулар мен мәтінмен жұмыс жасаудың тиімді әдіс-тәсілдерімен ұштастыра қолдану қажет деген тұжырым жасалды. Кілт сөздер: қазақ тілі, қатысымдық дағдылар, қатысымдық жаттығулар, рөлдік ойын, пікірталас, топтық тапсырма, грамматикалық жаттығулар, мәтінмен жұмыс.

The purpose of this paper is twofold. On the one hand, the paper draws a comparison between the national entrepreneurial potential and characteristics in Romania and Greece, using the Global Entrepreneurship Monitor (GEM) statistics. On the other hand, the paper aims to investigate the students’ entrepreneurial potential and the role of education, considering the case of two technical universities, one from Greece and one from Romania. While at national level the latest GEM data indicates a higher entrepreneurial potential for Romania, the institutional comparison made, and the statistical data processing, underline the gap of entrepreneurial education in both universities. More precisely, using the questionnaire approach, we show that students hardly perceive the role of courses related to entrepreneurship. Thus, the courses taught at the analyzed universities fail in highlighting and developing entrepreneurial skills, although their structure and topics are related to entrepreneurship. These results have practical implications and they serve to find solutions for improving the entrepreneurial education in both institutions.

The prediction of new Covid-19 cases in Poland with machine learning models
Authors:   University of Economics in
            Katowice, Katowice, Poland, Chwila Adam
Published: May 2023

The COVID-19 pandemic has had a huge impact both on the global economy and on
everyday life in all countries all over the world. In this paper, we propose several
possible machine learning approaches to forecasting new confirmed COVID-19 cases,
including the LASSO regression, Gradient Boosted (GB) regression trees, Support Vector
Regression (SVR), and Long-Short Term Memory (LSTM) neural network. The above methods
are applied in two variants: to the data prepared for the whole Poland and to the data
prepared separately for each of the 16 voivodeships (NUTS 2 regions). The learning of
all the models has been performed in two variants: with the 5-fold time-series
cross-validation as well as with the split into the single train and test subsets. The
computations in the study used official statistics from government reports from the
period of April 2020 to March 2022. We propose a setup of 16 scenarios of the model
selection to detect the model characterized by the best ex-post prediction accuracy. The
scenarios differ from each other by the following features: the machine learning model,
the method for the hyperparameters selection and the data setup. The most accurate
scenario for the LASSO and SVR machine learning approaches is the single train/test
dataset split with data for the whole Poland, while in case of the LSTM and GB trees it
is the cross validation with data for whole Poland. Among the best scenarios for each
model, the most accurate ex-post RMSE is obtained for the SVR. For the model performing
best in terms of the ex-post RMSE, the interpretation of the outcome is conducted with
the Shapley values. The Shapley values make it possible to present the impact of
auxiliary variables in the machine learning model on the actual predicted value. The
knowledge regarding factors that have the strongest impact on the number of new
infections can help companies to plan their economic activity during turbulent times of
pandemics. We propose to identify and compare the most important variables that affect
both the train and test datasets of the model.
A new confidence interval for the odds ratio
Authors: Zielińska-Kolasińska Zofia , Zieliński Wojciech
Published: May 2023

consider the problem of interval estimation of the odds ratio. An asymptotic
confidence interval is widely applied in economics, medicine, sociology, etc.
Unfortunately, this confidence interval has a poor coverage probability, significantly
smaller than the nominal confidence level. In this paper, a new confidence interval is
proposed. Its construction requires only information on the sizes of samples and the
sample odds ratio. The coverage probability of the proposed confidence interval is at
least the nominal confidence level.
Determinants of livestock products export in Ethiopia

            University, Ethiopia, Kefelegn Ermyas
Published: May 2023

Ethiopia has one of the largest livestock populations in Africa. In 2016–2017, the
share of live animals, leather, and meat in the total export of the country reached
9.6%. This paper aims to identify the determinants of the export of Ethiopian livestock
products by means of vector autoregressive and vector error correction models.
Multivariate time series is used to model the association between the products of the
Ethiopian livestock export included in the study. Vector autoregressive and vector error
correction models are used for modelling and inference. The results indicated the
existence of a long term correlation between the volume of live animals, meat and
leather exports. The volume of meat export is significantly affected by a lag occurring
in the export of live animals in the short-run. Therefore, 3.7% of the shortrun
imbalance in the volume of leather export is adjusted each quarter. It is suggested that
the exporters of livestock products should properly utilise the Ethiopian livestock
resources. On the other hand, the government should offer different forms of support to
exporters, especially those focusing on exporting value-added products.

This paper considers some efficient classes of estimators for the estimation of
population mean using known population proportion. The usual mean estimator, classical
ratio, and regression estimators suggested by Naik and Gupta (1996) and Abd-Elfattah et
al. (2010) estimators are identified as the members of the suggested class of
estimators. The expressions of bias and mean square errors are derived up to first-order
approximation. The proposed estimators were put to test against various other competing
estimators till date. It has been found both theoretically and empirically that the
suggested classes of estimators dominate the existing estimators.

            Medicine, Toronto, Canada, Campanelli Leonardo
Published: May 2023

Using the Euclidean distance statistical test of Benford’s law, we analyse the
COVID-19 weekly case counts by country. While 62% of the 100 countries and territories
considered in the present study conforms to Benford’s law at a significant level of α =
0.05 and 17% at a significant level of 0.01 ≤ α < 0.05, the remaining 21% shows a
deviation from it (p values smaller than 0.01). In particular, 5% of the countries
‘break’ Benford’s law with a p value smaller than 0.001.
