The problem faced by BRI Venture is to determine the feasibility of investing in Company A, a start-up in the student financing market in Indonesia. The valuation of start-ups in Indonesia is difficult, making it challenging for BRI Venture to assess the viability of the investment. This study aims to provide a comprehensive analysis of the factors affecting Company A’s business, both internally and externally, in order to make an informed investment decision. The study focuses on three key research objectives: (1) to examine the macroeconomic and industry impact on Company A’s business by using Porter’s Five Forces model, PESTLE model, and market sizing; (2) to examine the internal aspects impacting Company A’s business by using the VRIO model; and (3) to determine the valuation of Company A by using the DCF and relative valuation methods. The findings of the study reveal that the Indonesian student financing market presents both opportunities and challenges. The PESTEL analysis highlights the increasing demand for student loans in Indonesia, creating growth opportunities for the industry. However, the Five Porter framework analysis highlights the intense competition, strong buyer bargaining power, and weak supplier bargaining power, which may make it difficult for new entrants to succeed. The VRIO Framework analysis suggests that Company A has a number of sources of sustained competitive advantage, including adaptable repayment terms, technological capabilities, and market position, indicating that Company A’s internal situation is strong. The Absolute Valuation and Relative Valuation results indicate that Company A valuation is between $59 million and $73 million. In conclusion, while the Indonesian student financing market presents a growth opportunity, BRI Venture must carefully consider the challenges and competition in the market before making an investment in Company A. The internal analysis of Company A suggests that it has a strong position in the market, with a range of assets and competencies that can offer a sustainable competitive advantage. The valuation results provide a range of potential equity stake that BRI Venture could ask for if an investment in Company A is made.

Digital content and influencer marketing leader PT. XYZ Located at the crossroads of content, platforms, and brands, aims to revolutionize content creation, distribution, and consumption in Asia. Singapore, Kuala Lumpur, Seoul, Tokyo, Manila, Shenzhen, Hong Kong, and Jakarta are the 8 Asia Pacific offices (including Philippine after the merger with Indonesia). Organizational reorganization is essential, according to PT. XYZ. After Q1–Q3 2021 revenue declines, this campaign was launched. Employee readiness to adopt the new organizational structure must be assessed. This study assesses staff readiness for the new organizational structure and then determines the best approach to address current and future results. For the Managing Director and HR Manager, the writers use the Kotter 8-Steps model, followed by the ADKAR model for Leader Functions and their personnel. This study found that employees are aware of company changes, although their views on the need for change vary. Some employees reject the idea despite knowing it will boost business success. This is largely due to a lack of accurate information and change-specific training. Because leaders want to help, employees are ready for change. Unfortunately, there is no assessment system with clear success criteria, making it difficult to determine which appraisals were beneficial. Especially without prizes or recognition to motivate improvement. Thus, improvements are needed, such as forming appropriate guiding coalition teams with the same goals, one-on-one meetings with employees, providing training to support new hires, launching short-term wins, publishing change progress reports, and HR system alignment in compensation, promotion, and succession planning.
Grass pea (Lathyrus sativus) a Crop of Future for Sustainable Agriculture in The Changing Environmental Conditions
Authors:   Reliance Industries Ltd., Jamnagar Gujarat, P.S Chandrashekharaiah
Published: February 2023

Grass pea (Lathyrus sativus) is an ideal pulse crop for sustainable agriculture due to its superior agronomic traits such as deep penetrating root system, resistance to many biotic and abiotic stresses and rich protein content. Even with these superior agronomic traits, the crop is considered as an orphan due to its lower productivity and presence of neurotoxin, b-N-ozalyl-L-adiamino-propanoic acid (ODAP). By following classical and mutational breeding approaches scientists have developed varieties with lower ODAP (< 0.06 %) and efforts are underway to reduce it to zero. However, till date, there are limited biotechnological research in Lathyrus sativus for targeted crop improvement due to unavailability of genome sequence. The recently published draft genome sequence of European accession (LS007) is an important breakthrough and this would help in developing varieties with lower neuro toxin and higher productivity. In this review, the superior agronomic traits, resilience of the crops to various biotic and abiotic stresses, latest genetic research and biotechnological tools developed in L. sativus, are discussed.

Problem solving is now, one of the major skills of the 21st century. In this context, the STEM (Science, Technology, Engineering and Mathematics) approach goes beyond the teaching of school subjects, and the teaching-learning of mathematics should allow learners to appropriate skills of problem solving and solution finding in different life situations. In fact, solving mathematical problems generates cognitive, metacognitive, affective and emotional processes. Therefore, the visualization of these processes allows teachers to implement adequate pedagogical strategies aimed at the development of learners' abilities and skills to solve mathematical problems. In the context of a digital pedagogy, its allowing the designers of computer systems to model the processes in order to set up intelligent tutorial systems (expert systems) helps in the development of mathematical problem solving skills. We present in this article a methodological and analytical approach allowing to verbalize, visualize the networks of resolution of mathematical problem and to represent them schematically. We conclude with a modeling of these networks.
The Impact of Industry Specialist on the Relationship between Returns and Future Earnings
Authors: Huang Han-Ching , Huang Yung-An
Published: February 2023

Abstract

Financial statements reveal the company's profitability and be used as an important indicator of the risk assessment. Auditor industry specialists can provide better quality of financial reports and informative disclosures. According to Lundholm and Myers (2002), we examine whether the fact that accountants or audit firm are industry specialists will affect the relationship between returns and future earnings. Since there exists the special system of dual attestation in Taiwan, we divide the accountants into lead auditors or concurring auditors to examine the above relationship. Empirical results indicate that the higher future earnings response coefficients are associated with the companies audited by industry specialist, the higher number of industry specialists, the more industry experience of industry specialists and the greater market value of company. These findings imply that more information about future earnings are revealed. Therefore, it improves the disclosure of company's future earnings when the accountants or audit firms are industry specialists. In addition, we do not find the evidence that the future earnings response coefficients in companies audited by the lead auditor as industry specialist are higher than those in companies audited by the concurring auditor as industry specialist and in specialist accounting firms.

Published: February 2023

The presented article focuses on Early Bronze Age artefacts made from hard
animal materials found in the south Moravia region. This topic tends to be
neglected in the literature, as these artefacts are not as numerous as ceramics
or bronze objects. However, their study can bring important knowledge. Open
rural settlements of the Early Bronze Age are compared. Two sites are dated
to the Únětice culture, the third to the Věteřov group. Processed assemblages are the largest known collections of artefacts from the period in south Moravia. The main aim of the thesis is a detailed analysis of the assemblages, which consist mainly of objects assembled from bones and antlers; the use of other raw materials is rare. The article compares the production of artefacts between the earlier Únětice and later Věteřov phases. It briefly addresses the find circumstances and contexts of individual artefacts. The analytical part includes an osteological determination of raw materials used for the production of artefacts. It focuses on a morphological and typological description of
objects based on new descriptive standards in an effort to revise previously used subjective terms such as awl. The third part of the analysis is devoted to a study of use-wear marks created in the production and use of individual artefacts or their archaeologisation. The discussion addresses the possibilities of interpreting and identifying the function of individual objects on the basis of the above analyses.

MIGRATION OF MEDICAL PROFESSIONALS IN HUNGARIAN HEALTHCARE SECTOR – LITERATURE REVIEW
Authors: KOCSICSKA IVANA Ivana
Published: February 2023

Medical migration is a global phenomenon, an important challenge of globalization and the current global economic trend, which plays a critical role in the operation and maintenance of healthcare systems. This applies to Hungary as well, the migration of health professionals has been a problem that has seriously threatened the Hungarian healthcare system for at least 20 years. In my research, I conducted an integrative literature review of 8 scientific articles about the migration of Hungarian healthcare professionals published in the last 5 years (2018-2022), which I found in the PubMed and ScienceDirect publication databases. The aim of my review study is to provide a complete and satisfactory summary of the literature examining and analyzing the current migration trend in Hungarian healthcare, as this way, even with the lack of the official statistical data, we can gain insight into the current situation. Examining the profile of migration, it can be seen that the situation is most critical in the professions of internal medicine, family medicine, and infant and pediatric medicine in terms of medical specialization, while and in terms of country provision and demographics, there is the most prominent shortage of specialists in Békés, Nógrád, Jász-Nagykun-Szolnok, Tolna and Szabolcs-Szatmár-Bereg counties compared to other counties. The labor crisis in Hungarian primary healthcare is gradually escalating and also within ten years, Hungary will face a severe shortage of pediatricians. Optimizing the working conditions of healthcare workers is a political and social interest, which would probably take a long time, but could ensure high-quality care in the long run. One of the most important conclusions of the review is that Hungarian healthcare workers abroad left primarily because of better quality of life and more favorable financial conditions, but some of the research results showed, that changes in these conditions at home would encourage them to return home.

RESEARCH ON THE PERCEPTION OF ROMANIAN PRE-UNIVERSITY TEACHERS ABOUT THE RELATIONSHIP BETWEEN E-LEADERSHIP AND MOTIVATION
Authors: ENE (CONSTANTIN) Andreea Bianca ENE (CONSTANTIN)
Published: February 2023

E-leadership research has evolved significantly in recent times, influencing the development of the education system, which has been affected by the effects of the pandemic. In order to keep up with the changes, teachers have had to adapt to the ever-changing requirements and opportunities. The topic of the paper refers to the perspective of Romanian pre-university teachers regarding the connection between e-leadership and motivation. The reason I chose to do this research is because e-leadership is a current topic. On the other hand, I am a teacher in the pre-university education system and I started my teaching activity in the middle of the pandemic and I can say that it was a real challenge for me to integrate remotely into a new team. Therefore, I found it opportune to study this subject, the paper being based on the identification of the main advantages and barriers of e-leadership in motivating employees. For this, I will look for the answer to the research question “What is the perception of pre-university teachers regarding e-leadership?”, by sending a questionnaire among teachers. To answer this question, I carried out a quantitative research of a structured survey type, based on a questionnaire with 16 items, addressed to pre-university teachers, regarding the link between e-leadership and employee motivation. This survey was conducted online, in 1st-4th November 2022, through Google Forms, and I processed and interpreted the obtained data, using Microsoft Excel and SPSS statistical software. I hope this paper will be useful to all those interested in this topic, especially PhD students and leaders who want to deepen this topic.
THE IMPACT OF THE CRISIS CAUSED BY THE COVID-19 INFECTION ON THE BUSINESS ENVIRONMENT
Authors: DRĂGAN-CODREAN Cosmina-Ioana , FORA Andreea-Florina
Published: February 2023

This paper intends to analyze how the crisis produced by the Covid-19 infection has influenced the employees, respectively the employers. Thus, we try to see if they still approach the workplace, working hours, etc. in the same way or if their perception has been decisively influenced by this crisis. Certainly, there is an impact on the business environment around the world, respectively in Romania. Thus, employers and employees, like the whole world, had to adapt and reorganize in the given conditions. Some views support the theory that, for employers and employees respectively, nothing will be the same, and the approach and expectations of both parties will be different. Other views argue that this crisis will not cause major changes in perception on the subject. Be that as it may, through this paper we try to analyze in what way and above all, what changes this crisis has produced on the employees, respectively the employers. For the most part, for the employee, the workplace is the place from where he procures an important part or even all of his financial resources. Besides, the workplace is also the place where he can prove his skills acquired in school, the place where he socialises, the place where he develops professionally and not only that. The employer, in general, wants a competent and efficient employee. Both regarding employees and employers, the crisis caused by the Covid-19 infection has produced important changes that we will study in the analysis below. The business environment around the world has seen changes with the situation caused by this crisis that has faced all of humanity. Also, before analyzing, in broad terms, the impact on the business environment, we must observe how people saw the involvement, from a diplomatic point of view, in Romania’s economic development. Economic development must also be supported at the diplomatic level, not only through the other available levers.
CONSTRUCTION OF A BACTERIAL STRAIN FORMING INCLUSION
BODIES, EXHIBITING DIADENYLATE CYCLASE ACTIVITY
Authors: Vinter M. A. , Kazlouski I. S. , Zinchenko A. I.
Published: February 2023

Using Recombinant DNA Technology, the novel bacterial recombinant strain Escherichia coli DAC-22, a source of diadenylate cyclase that catalyzes the transformation of adenosine-5′-triphosphate into cyclic 3′,5′-diadenylate (cyclo-di-AMP), was developed. The strain was derived by the transformation of E. coli Rosetta (DE3) pLysS cells with the recombinant plasmid pET42a+ wherein the disA gene responsible for the synthesis of the diadenylate cyclase of Bacillus thuringiensis was inserted. The producing capacity of the new strain with respect to diadenylate cyclase localized in catalytically active inclusion bodies equaled 720 units per liter of liquid culture. The newly engineered strain is destined for use in the technology related to the production of pharmaceutically promising cyclo-di-AMP.
Extreme Bound Analysis Based on Correlation Coefficient for Optimal Regression Model
Authors: Nguyen Loc
Published: February 2023

Regression analysis is an important tool in statistical analysis, in which there is a demand of discovering essential independent variables among many other ones, especially in case that there is a huge number of random variables. Extreme bound analysis is a powerful approach to extract such important variables called robust regressors. In this research, I propose a so-called Regressive Expectation Maximization with RObust regressors (REMRO) algorithm as an alternative method beside other probabilistic methods for analyzing robust variables. By the different ideology from other probabilistic methods, REMRO searches for robust regressors forming optimal regression model and sorts them according to descending ordering given their fitness values determined by two proposed concepts of local correlation and global correlation. Local correlation represents sufficient explanatories to possible regressive models and global correlation reflects independence level and stand-alone capacity of regressors. Moreover, REMRO can resist incomplete data because it applies Regressive Expectation Maximization (REM) algorithm into filling missing values by estimated values based on ideology of expectation maximization (EM) algorithm. From experimental results, REMRO is more accurate for modeling numeric regressors than traditional probabilistic methods like Sala-I-Martin method but REMRO cannot be applied in case of nonnumeric regression model yet in this research.

Authors: Wang Wendong
Published: February 2023

The necessity and viability of combining moral education cultivation with labor education are becoming more and more apparent in the context of the new era. We investigate the practical means of fusing ideological and political education with labor education, using the Marxist perspective of labor as the theoretical framework and integrating the current realistic labor situation of college students in China. We may promote college students' labor consciousness, labor emotion, respect for labor, and love for labor through the practical activities of ideological and political education and labor education.We fully acknowledge the students' primary role in the process of moral education, allow them to actively engage in learning and work, integrate ideological and political education materials that have a global impact and provide useful advice for students' lives and growth into their daily lives, and achieve a profound integration of moral education cultivation and labor education for college students.
A Rare Case of Spasmus Nutans in an Infant
Authors: Umali Maria Isabel N. , Cruz Franz Marie O.
Published: February 2023

We report a case of an otherwise healthy 23-month-old boy who presented with nystagmus, head shaking, andabnormal head posture suggestive of spasmus nutans. Neuro-ophthalmologic exam revealed bilateral, low-amplitude, high-frequency, horizontal, disconjugate nystagmus that was more prominent in one eye along with head shaking and a head tilt or face turn. The rest of the exam and the systemic physical examination were normal. Magnetic resonance imaging of the brain did not disclose optic pathway glioma, which has been reported to cause spasmus nutans-like disease. Electroretinogram (ERG) was also recommended to rule out occult retinopathies. However, it was not done due to unavailability of the appropriate corneal electrode for his age. Instead, close follow-up was advised to monitor spontaneous improvement or resolution, or until the child comes of age that he can undergo ERG. This case highlights the management approach and rationale of patients with presumed spasmus nutans. Recognition of the triad of spasmus nutans allows for quick diagnosis and more focused and efficient investigation.

Published: February 2023

Background. Intravitreal chemotherapy has been an effective addition in treating vitreous seeding in retinoblastoma. However, it was only in 2020 that it was used in the Philippines. There is no literature on its use in multiple Filipino retinoblastoma patients.Objectives. To describe the clinical course of the four patients who are the first to undergo intravitreal chemotherapy for vitreous seeding of retinoblastoma in the Philippine tertiary hospital.Methods. A case series of four eyes of four patients with retinoblastoma who underwent intravitreous injectionof melphalan and topotecan for vitreous seeding at the Department of Ophthalmology and Visual Sciences of aPhilippine tertiary hospital.Results. Two eyes, with International Intraocular Retinoblastoma Classification (IIRC) Group C with vitreous seeding, responded well to intravitreous melphalan and topotecan. One eye had recurrent vitreous seeding despite 10 intravitreal injections. One eye with IIRC Group E, did not respond to intravitreous chemotherapy and was eventually enucleated.This is the first case series on the local use of intravitreous chemotherapy in the country for vitreous seeding inretinoblastoma. The control of 50% achieved in this case series is lower than in other series due to longer treatment interval from poor follow-up and the presence of advanced disease.Conclusion. The use of intravitreous melphalan and topotecan can be an effective adjuvant for systemic chemotherapy in controlling vitreous seeding in eyes with IIRC Group C. It is not effective in controlling IIRC Group E disease.

Published: February 2023

A field experiment was conducted in a farmer field in Nakhon Ratchasima province, northeast, Thailand objectively to investigate the response of cassava, Huay Bong 80 variety to phosphorus (P) fertilizer in Warin soil series (classified as Grossarenic Paleustults) amended with cassava tails and stalk (CTS) mixed with bentonite (BTN).  The experiment was arranged in split plot with four replications.  Main plot consisted of four rates of CTS +BTN: 0+0, 6.25+1.25, 12.5+2.5 and 25+5 t/ha while subplot comprising four rates of P fertilizer: 0, 25, 50 and 100 kg P2O5/ha.  Cassava was harvested at 12-month of age and plant samples were collected at the harvesting time to study the effects of soil amendment on the uptake of primary plant nutrients in different plant parts of cassava.  The results showed that the CTS+BN mixture at the rate of 25+5 t/ha highly significantly promoted the highest fresh tuber yield (FTY) and starch yield (SY) of 31.79 and 8.97 t/ha, respectively, which were 21.2 and 20.7 % greater than that of the control with no soil amendment addition. Increasing rate of P fertilization highly significantly induced greater FTY, SY and aboveground biomass (ABG) than did the zero-P fertilization. Amending the soil with 25+5 t/ha of CTS+BN along with the addition of 100 kg P2O5/ha interactively gave the significantly highest respective FTY, SY and ABG of 39.76, 11.48 and 17.35 t/ha whereas the plot amended with 12.5+2.5 kg CTS+BN/ha plus 50 kg P2O5/ha fertilization gave slightly lower STY and SY of 36.11 and 10.30 t/ha, respectively.  The former combined rate of soil amendment and P fertilizer also had the interaction that highly significantly induced the highest uptake of all primary plant nutrients in the whole plant, accounting for 131.66, 14.23 and 124.13 kg/ha of respective nitrogen, phosphorus, and potassium.  The result reaffirmed that amending the soil with proper rate of CTS+BTN mixture enhanced the efficiency of P fertilizer and subsequently improved yield of cassava.
HIGHLIGHTS

Coarse-textured soils in northeast Thailand are very poor physically and chemically, leading to low yield of cassava planted
Improving the soils with proper soil amendments combined with phosphorus fertilization can be beneficial to an increase of cassava yield
Amending Warin soil series, one of the coarse-textured soils in this region, with 25+5 t/ha of cassava tails and stalk + bentonite along with the addition of 100 kg P2O5/ha interactively gave the significantly highest fresh tuber yield, starch yield and aboveground biomass of cassava

Published: February 2023

Understanding the effect of vaccination on the body of chickens is impossible without exploring the morphology of the immune defence organs. The purpose of the study was to identify morphological changes in the Harderian gland of the Haysex Brown chickens aged 1, 15, 25, 50, 75, 100 and 120 days under the influence of vaccination. The following methods were used in the study: anatomical, histological, light-optical, morphometric, and statistical. Histological preparations of the Harderian gland of chickens of different ages (1, 15, 25, 50, 75, 100 and 120 days) of the vaccinated and unvaccinated groups were analysed. The features of the organ structure, its lymphoid structures and their types of forms were explored on histological preparations of the chicken Harderian gland. According to histological studies, it was established that this is a complex tubular lobular gland, which consists of secretory lobules with ducts. The interlobular connective tissue contains a significant number of lymphocytes, plasma cells, and other cells. In vaccinated chickens at 25 days of age, the presence of diffuse lymphoid tissue was noted, which was not observed in the control group, and at 50 days of age - the development of a nodular form of lymphoid tissue, the maximum number of which was observed at 100 days of age. In chickens of 75, 100, and 120 days of the age of the experimental group, the amount of lymphoid tissue in the Harderian gland increased, which was noted in the interlobular connective tissue and secretory lobules. It has been proven that the chicken gland, as a peripheral organ of immune defence, is developed at 50 days of age in both the control and vaccinated groups. The study of morphological changes in the Harderian gland of the poultry of different ages is an important tool for the development of preventive vaccination protocols in modern poultry farming. The results of the study should be considered when improving the technology of rearing and exploitation of chickens to ensure high vitality and, accordingly, productivity

A reliable element of the technology for growing environmentally friendly products of early-ripening soybean varieties, and improving soil fertility, is the introduction of environmentally friendly growing technology based on the optimal functioning of the symbiotic system, without using mineral fertilisers, in particular nitrogen and pesticides. The purpose of the research was to explore the effect of inoculation of seeds of diverse soybean varieties with nitrogen-fixing and phosphorus-mobilising preparations, foliar fertilisation and their combination on growth, plant development and productivity under organic cultivation technology. The research was conducted using generally accepted methods, the field method, and the method of statistical evaluation of results. Experimental studies have established that with the introduction of high-yielding soybean varieties, using post-harvest residues (straw, stubble and root residues), green manure and legumes in a short rotation crop rotation, 136 kg of nitrogen and 142 kg of biologically fixed nitrogen enters the soil. It was demonstrated that seed treatment with AgriBacter inoculant and soybean fertilisation with Nanovit Super complex fertiliser ensures a yield of 4.08 t/ha for Mentor and leaves almost 30% of biological nitrogen in the soil. Studies have demonstrated that an integrated approach to the treatment of soybean seeds of the tested varieties with AgriBacter and Phosphoenterin inoculants, a strain of bacteria that decomposes hardly soluble organic phosphates, which in turn contributes to better nutrition of soybean plants, development of the root system, and has a positive effect on the development of an optimal stem density of 410-490 thousand units/ha, which provides an increase in the yield of soybean varieties by 1.88 t/ha. It was established that simultaneous inoculation of seeds and foliar feeding of soybeans with the biologically active complex Nanoactiv with the addition of magnesium sulfate in the macrostage BBCH 60-63 provides the highest yield of Niagara variety – 4.08 t/ha and Astor variety – 2.88 t/ha. Thus, in a shortrotation 4-season crop rotation saturated with legumes, using nitrogenfixing, phosphorus-mobilising preparations and the active growth stimulator Nanovit Super + Magnesium sulfate, soil fertility increases and the nitrogen content in the soil doubles. The scientific results can become the foundation for improving soil fertility, which will ensure sustainable yields in organic soybean cultivation
Training and Performance of Public Procurement Professionals in Tanzania: The Mediating Role of Career Development
Authors: Jaffu Richard
Published: February 2023

Training and career development have been considered to improve employee performance because better-quality human capital is vital in enhancing employee performance. This study analysed the influence of training on the performance of public procurement professionals when mediated by career development in Tanzania. The study used a cross-sectional research design involving 204 public procurement professionals from Dodoma city in Tanzania. The study applied Confirmatory Factor Analysis (CFA) as a part of Covariance Based-Structural Equation Modelling (CB-SEM) and Hayes' PROCESS macro to analyse the data and determine the relationship between the training and performance of public procurement professionals when mediated by career development in Tanzania. The results show that training and career development determine the performance of public procurement professionals. Training facilitates the career development of public procurement professionals, whereas career development mediates the relationship between training and the performance of public procurement professionals. This study only considers training and career development, among other aspects of human resource development practices. This excludes the other human resource development practices in public organisations. This study brings together human resource development concepts (training and career development) and the performance of public procurement professionals. Thus, it adds value to the literature on human resource management concerning the performance of public procurement professionals.

El soporte constructivo del Renacimiento español es la sillería aplantillada. Para obtener las plantillas que permiten la labra de los sillares, es preciso dibujar las piezas que conforman la fábrica a tamaño natural. Estos trazados se conocen como monteas y son documentos relevantes de la Historia de la Construcción. En el Colegio de Nuestra Señora de la Antigua, edificio renacentista sito en Monforte de Lemos, se conservan varios trazados de montea. Hasta ahora se tenía noticia de dos de ellos, levantados y explicados con anterioridad, a los que este texto añade varios más formando un conjunto que permite hablar de una verdadera ‘Ruta de las Monteas’. Se explica el porqué de la conservación de estos trazados en base a la historia de la construcción del edificio y se señalan algunos datos constructivos clave que destacan en la revisión histórica realizada.
Urban Life in the Middle Ages 1000-1450
Authors: Lilley Keith D.
Published: February 2023

What was life like in towns and cities in medieval Europe? How did people live, and why was it that some towns grew into major urban centres while others did not? After the year 1000, all across Europe urban life prospered as it had never done before. New towns emerged, and established towns and cities grew larger and became more powerful and dominant. During the later Middle Ages these towns and cities were the focus of religious, political, commercial and social activity; the places where power, profit, piety and people all came together. Urban life was indeed the making of medieval Europe.

Drawing upon original research, as well as the work of medieval historians, urban archaeologists and historical geographers, Keith Lilley explores the close relationship that existed between the life of towns in the Middle Ages and the life within towns. Taking a fresh and challenging approach, this richly-illustrated book will be invaluable to anyone interested in medieval Europe. It focuses on important themes, including lordship, property, and townscape, and explores the processes which not only shaped the towns and cities of medieval Europe, but also the people who lived in them.
A novel algorithm of data mining to predict future scenarios of COVID-19 pandemic
Authors: Shaheen, PhD Muhammad
Published: February 2023

COVID-19, a novel coronavirus, is an ongoing global pandemic that has outbroken recently and spread to almost every part of the world. Several factors of this pandemic are still unknown to the world, which causes uncertainty to prepare a strategic plan to cope with this disease effectively and securing the future. A large number of research is in progress or expected to start shortly on the basis of the publicly available datasets of this deadly pandemic. The data are available in multiple formats that include geospatial data, medical data, demographic data, and time-series data. In this study, we propose a data mining method to classify and forecast the time-series pandemic data in an attempt to predict the expected end of this pandemic in a particular region. Based on the COVID-19 data obtained from several countries around the world, a naïve Bayes classifier is built, which may classify the affected countries into one of the following four categories: critical, unsustainable, sustainable, and closed. The pandemic data collected from online sources are preprocessed, labeled, and classified by using different data mining techniques. A new clustering technique is also proposed to predict the expected end of the pandemic in different countries. A method to preprocess the data before applying the clustering technique is also proposed. The results of naïve Bayes classification and clustering techniques are validated based on accuracy, execution time, and other statistical measures.
Structures for collaboration and networked adaptation: Emerging themes from the COVID-19 pandemic

The COVID-19 pandemic is a crisis that is “creeping” in its onset and “slow-burning” in its duration. It is characterized by extreme uncertainty, ambiguity, and complexity, presenting an unprecedented need for response across sectors and political-administrative levels. While there has been an explosion of research papers into the national strategies for handling the pandemic, empirical publications on the local and regional management are still scarce. This paper presents early empirical insights into key collaborative functions in Norway and Sweden, with an ambition to contribute to a research agenda focusing on the collaborative practices of pandemic crisis management. Our findings point to a set of themes that are all related to emerging collaborative structures, that fill holes in pre-established structures for dealing with crises, and that have been important for being able to effectively deal with the pandemic. At the municipal and regional levels, we see more examples of well-adapted collaborative practices than we see the wickedness of the problem causing inertia and paralysis. However, the emergence of new structures indicates a need to adapt organizational structures to the existing problem, and the duration of the current crisis allows for significant evolution of collaborative structures within the various phases of the pandemic. The lessons that can be drawn from this reveal a need for reconsideration of some of the basic assumptions of crisis research and practice, in particular the so-called similarity principle that is a cornerstone of emergency preparedness organization in many countries, including Norway and Sweden.
