The Role of Poverty, Food Security, and Rapid Population Growth on Human Development in Pakistan
Authors: Ur Rehman Mujeeb , Ahmed Aziz , Khan Anwar , Khan Ajmal
Published: March 2023

This study examines the relationships among poverty, food security, rapid population growth, and human development in Pakistan over 1990-2018 to achieve the targets of Sustainable Development Goals (SDGs) 1: No poverty and 2: Zero Hunger. The study applies time series based econometric approaches, which have the ability to incorporate regime shifts in the estimation process. The Zivot and Andrews unit root test is supplied for first-order integration, Bound, and Gregory Hansen cointegration tests to support the cointegration relationship among the variables. Similarly, the results obtained from autoregressive distributed lags (ARDL) stated that food security and income growth simultaneously increase human development in Pakistan. In contrast, the role of rapid population growth is negatively affecting human development in the country. The results from fully modified ordinary least squares (FMOLS) and canonical cointegrating regression (CCR) are simultaneously supporting the results of ARDL. The estimates of Granger causality revealed that income is unilaterally, and population growth is bi-directionally, causing human development in Pakistan. Similarly, the causality from human development to food security is also unidirectional. Finally, the study informs policymakers to devise effective policy guidelines for achieving the targets of SDGs 1 and 2 for Pakistan.

Корпоративная аналитическая платформа – необходимый атрибут современного бизнеса, однако разные компании находятся на разных уровнях зрелости процессов принятия решений. Для оценки реального положения конкретных компаний нужна шкала зрелости.

A corporate analytics platform is a must for a present-day data-driven business. That said, companies are uneven in the maturity level of decision-making processes defined by modern platforms like that. To assess the actual status of a specific company, as well as to compare businesses with each other, a maturity scale is needed that would indicate the position of a company on a digital business transformation journey.
Probabilistic modelling of substorm occurrences with an echo state network
Authors: Nakano Shin'ya , Kataoka Ryuho , Nosé Masahito , Gjerloev Jesper W.
Published: March 2023

Abstract. The relationship between solar wind conditions and substorm activity is modelled with an approach based on an echo state network. Substorms are a fundamental physical phenomenon in the magnetosphere–ionosphere system, but the deterministic prediction of substorm onset is very difficult because the physical processes that underlie substorm occurrences are complex. To model the relationship between substorm activity and solar wind conditions, we treat substorm onset as a stochastic phenomenon and represent the stochastic occurrences of substorms with a nonstationary Poisson process. The occurrence rate of substorms is then described with an echo state network model. We apply this approach to two kinds of substorm onset proxies. One is a sequence of substorm onsets identified from auroral electrojet intensity and the other is onset events identified from Pi2 activity. We then analyse the response of substorm activity to solar wind conditions by feeding synthetic solar wind data into the echo state network. The results indicate that the effect of the solar wind speed is important, especially for Pi2 substorms. A Pi2 pulsation can often occur even if the interplanetary magnetic field (IMF) is northward, while the activity of auroral electrojets is depressed during northward IMF conditions. We also observe spiky enhancements in the occurrence rate of substorms when the solar wind density abruptly increases, which might suggest an external triggering due to a sudden impulse of solar wind dynamic pressure. It seems that northward turning of the IMF also contributes to substorm occurrences, though the effect is likely to be minor.
Wissenschaftliche Episteme und Geltung. Von der Konstruktion zum Dialog
Authors: Goeke Pascal
Published: March 2023

Abstract. The long triumph of constructivism, particularly visible works such as
Kuhn's writing on the structure of scientific revolutions, and many other
scientific studies have made one thing clear: Reason alone does not decide
on scientific topics, theories, and methods. Instead, very different
factors, often considered illegitimate, help determine the course of
science. These findings make scientific enlightenment gestures recurrently
appear as sheer mockery, undermine the validity claims of scientific
statements, open up possibilities for a strong politicisation of science and
block any retrograde way out. Those who are nevertheless convinced of the
importance of scientific autonomy, who defend a special validity of
scientific knowledge and who accept the scientific duty of responsiveness,
should acknowledge the decision-making challenges in science and, as the
article recommends, engage in theory-theoretical dialogues.

Authors: Monira U. , Sattar G. S. , Golam Mostafa Md.
Published: March 2023

The industry discharges a large volume of effluent, many of which contain lots of chemicals and toxic substances that have the potential to cause distress to the environment. The study focused on analyzing various physicochemical parameters of the effluent discharge from the Central Effluent Treatment Plant (CETP) at the Savar Tannery Industrial Zone. The effluent was collected four times (pre-monsoon, monsoon, and post-monsoon) a year, from 2021-2022. The effluent was inspected for vital water quality parameters, such as pH, COD, BOD, TDS, TSS, NO3-, SO42-, HCO3-, PO43-, Cl-, Na, Ca, Cr, Fe, Cu, Zn, and Pb. Most of the parameters exceed the standard permissible limit of the Department of Environment, Bangladesh (DoE, BD), NQES, and ISW-BDS for inland water. The mean concentrations of COD, BOD, TSS, and Cr were 337, 97.5,  209, and 6.1 mg/L, and these values were far above the permissible limit with a removal efficiency of 51%. The study observed that industrial discharge of unproperly treated effluent deteriorates the surface water quality and causes huge threats to aquatic life and sustainable water resource management.

Authors: Petrovič Ján , Mellen Martin
Published: March 2023

The study aimed to examine laying hens in the cage and cage-free breeding systems, the quality of table eggs and energy consumption in the hall after the peak of laying. In the research, the following were investigated and statistically evaluated welfare of laying hens Bovans Brown was monitored in three different rearing systems based on resources and animals. The research was designed into the post-peak laying period, at the age of laying hens from 34 to 47 weeks and a rearing system of enriched cages on deep litter and in aviaries. Statistical analyses of the measured data of the established indicators were performed with the SAS program package, version 8.2, for statistical characteristics, significance, and correlation relations. The proportion of laying hens dying was lower in aviaries compared to cages and on deep litter (p ≤0.05); in cages and on deep litter was comparable (p ˃0.05). The weight of laying hens was comparable (p ˃0.05). Feed consumption per hen, day, and egg was highest on deep litter (p ≤0.05). The proportion of eggs with a cracked shell and contaminated with dropping was highest on litter (p ≤0.05). Energy consumption in the hall expressed per layer and day was comparable in all three breeding systems (p ≤0.05). Among some selected indicators of laying hen welfare, egg quality and energy consumption in the hall during breeding and correlation relations (p ≤0.05) were statistically significant within individual breeding systems. The question of laying hen welfare and improving cage-free systems because of the adopted legislation banning breeding in a cage system requires further research to adopt best practices regarding resource-based, management- and animal-based parameters. Based on the results about welfare conditions, including energy consumption in halls and egg quality, it is an open question for comprehensive, interdisciplinary research.

This study examines the scarcity of palm oil in Indonesia's CPO oil food commodity and the government's conservative steps through green resolution policies and strengthening local value chains. The validation of green economy resolution variable indicators in this study is green financing and local value chains in CPO exports as measured by product prices and production values. In addition to these variables, household consumption expenditure is the control variable used as a determining variable for CPO export levels. The research data uses data from the 2013Q1 to 2022Q4 time series. The research methodology describes the ARDL model for testing long-run effects and the ECM method for observing the economy's acceleration towards equilibrium during short-term shocks. The results showed that the long-term correlation between green financing resolution, product prices, and production value significantly affected the level of CPO exports at a significance level of 5% (p <0.05). However, the variable household consumption expenditure is not significant to the level of CPO exports in the long run at a significance of 5% (p <0.05). Then the short-term correlation shows that the green financing resolution variables, product prices, production values, and household consumption expenditures significantly affect the level of CPO exports at a significance of 5% (p <0.05).

Published: March 2023

Cocoa is a plantation commodity whose role is essential for the economy, so it is necessary to be aware of its health to maximize production. Cocoa plant disease data is a time series data because it is observed continuously. One of the time series forecasting models is the Fuzzy Time Series Markov Chain (FTS-MC), a combination of the Fuzzy Time Series (FTS) and Markov Chain models. The model uses the principle of fuzzy logic by transferring FTS data to fuzzy logic and using the obtained fuzzy logic groups to derive the Markov chain transition matrix. In this research, a Python script of the FTS-MC model was built in the Google Colaboratory to forecast the number of cocoa plant diseases in Bendungan District to simplify and speed up the data processing. Python was used in this research because of its easy-to-use, flexible, and open-source syntax. In building Python scripts, libraries and functions are needed by utilizing loop processes and if-else statements. Based on the processing results, forecasting with the FTS-MC model using Python only takes less than 1 minute.

Understanding the role of digital information in enhancing education in UAE: An investigation of the factors that drive continuous adoption
Authors: Alhumaid Khadija , AAssali Mouna
Published: March 2023

Digital information has had a significant impact on higher education, transforming the way students learn and interact with course materials, professors, and their peers. Education systems that place a high priority on learning satisfaction and tutor quality frequently ignore the problem of limited access to digital information and technology. In this study, we provide an integrated model that examines how the TAM constructs of digital information in education (DIE) are affected by digital information flow, technological readiness, learning satisfaction, and tutor quality. We provide information on the results of a project evaluation that examined how digital information is used in higher education. We gathered information from a survey of 594 college students to validate our model and hypothesis. Our research suggests that external factors that improve users' technological readiness and learning satisfaction may have an impact on how valuable they perceive DIE to be. A user's traits, particularly their level of technological preparedness, have a significant impact on how simple technology is to use. The user's perceived usefulness of the technology may also be further enhanced in some cultures by the tutor’s perceived excellence. External elements like the flow of information may have a significant impact on the intention to use technology.
Advances in additive number theory
Authors: Nicolás José Alfonso López
Published: March 2023

We obtain sufficient conditions to know if given a positive even integer number and a set of positive integer numbers being all even or all odd, such a number can be expressed as sum of two elements of this set. As consequence we obtain a result which, when applied to the prime numbers set, would prove Goldbach's Conjecture provided that certain conditions are satisfied. These hypothesis include Prime Consecutive Conjecture, which is a generalized form of Twin Prime Conjecture. In addition, we extend these results to sets of positive real numbers, even for two different sets. We also obtain a recurrent approximation of \pi(x) for enough large real x, being \pi the distribution function of the prime number set, which uses whichever expression of x as product of enough large factors. We also state this approximation in a more general context, give upper and lower bounds for the error, and show that this approximation is asymptotically equivalent to \pi(x).

Authors: Pudji Rahayu Retno , Sumaryono Bambang , Farikha Sandi Nadia
Published: March 2023

Type 2 diabetes mellitus is a disease caused by insulin resistance which will cause blood glucose levels to increase. That factor can result in an increase of proinflammatory cytokines such as TNF- dan IL-1 which will cause the severity of the disease gets worse. Intraoral antidiabetic drugs have several side effects; therefore, it is necessary to provide probiotic supplements such as Lactobacillus casei to reduce levels of TNF- dan IL-1 so that type 2 diabetes mellitus doesn’t get worse. These bacteria can also increase levels of anti-inflammatory cytokines such as IL-10. This study aims to learn and understand more deeply about the potential of Lactobacillus casei on TNF- and IL-1 levels in type 2 diabetes mellitus. Diabetes mellitus type 2 is a chronic disease by the pancreas not being able to produce the hormone insulin in large quantities due to insulin resistance caused by impaired insulin secretion in pancreas. TNF- and IL-1 is a cytokines that plays role in the body’s defense function, if cytokines produce in excess amount it will increase the inflammatory process. Lactobacillus casei is a probiotic bacterium that can be found in yoghurt, cheese, raw meat, and other food ingredients. Lactobacillus casei has the potential to reduce TNF- dan IL-1 levels in type 2 diabetes mellitus.

Published: March 2023

Over a sixth of the global total does not have access to clean drinking water. People in poor countries face a significant burden of diarrheal disease and other debilitating, life-threatening diseases due to a lack of adequate water. Fresh-water demand will continue to rise dramatically throughout the globe in the next years to satisfy the demands of rising people, developing economies, changes in lifestyle, and altering consumption behavior. It will also put even more strain on already scarce natural resources and ecosystems. As a result of overuse and water contamination, clean water has recently become a scarce fundamental commodity. In addition, the importance of new microbes in drinkable water has grown. Because of the serious implications of a drinking water source being polluted with pathogenic bacteria, prevention is important. The objective of this study is to find the quality of water whether or not it is suitable for drinking on the basis of physicochemical and microbiological assessment. In this study, we determine the water quality in terms of contamination rate such as chemical and microbiological to assure that the water we are drinking is safe for us as well as for other people. The testing was done as per IS 10500:2012 (Indian Standard) and APHA, USEPA for chemical and bacteriological analysis. The maximum numbers of chemical parameters were within the limits whereas this was not in the case of bacteriological parameter. The result of this study was that physical appearance is agreeable and disagreeable in some areas of Dehradun and in chemical appearance the amount of calcium is more than the limit and there is microbial contamination found in all water samples. From these studies, it is recommended that drinking water should be filtered and boiled. The water storage tanks should be washed in timely manner with chlorine tablets and chlorine liquid to avoid the contamination of water.
Introducing Larger plate and Optimum Distribution Pattern in Microbiological assay

Published: March 2023

First, clinical sample antibiotic assay process. 1966, Appl. Microbiol. 14:2:170–177. This modified agar-disks diffusion experiment employs big glass plates to enable 81 replications per plate. With an agar punch, more than agar disks may be made fast. The savings in zone of inhibition (zoi) from high repeated concentrations of diverse antibiotics with big plates and agar-disks makes it economically possible to employ pooled any antibiotic concentrate. Methods for creating disk diffusion agar and inhibiting bacterial susceptibility degradation are provided. Preparing and maintaining assay organisms is described. Instead of diluting antibiotic tablets to a small range at various concentrations to spread the agar well, they are tested immediately to avoid contamination at the tested concentrations. This is conceivable owing to antibiotic mobility (dilution) and curvilinear computations between area and antibiotic concentrations. This approach has been adapted to many antibiotics. With this technology, vast numbers of antibiotic disks may be tested quickly and accurately. Solid media can be used for antimicrobial susceptibility testing. Solids tests are straightforward and affordable, but they aren't quantitative. Antimicrobial agent diffusion may impair the accuracy of plate-based tests. After applying the above, we evaluated this assumption using the "Eight Queens Puzzle Model" of antibiotic dispersion and a disc diffusion test to estimate the connection between agar depth and area of inhibition and to determine the ideal agar depth. Our studies with agar-diffusion in plates and agar thickness demonstrated that this model describes antibiotic zoi sizes accurately. However, linear regression to explain the link between agar thickness and growth inhibition zone for Staphylococcus aureus and Escherichia coli treated with various antibiotic discs, three groups, the first group (erythromycin) emerged-zone equal sizes for both bacteria. Both bacteria were susceptible to gentamicin and ceftriaxone. Ciprofloxacin's three-group model fit best. Streptomycin's residual deviation was the same for both bacteria. The concentration dependency in the streptomycin group was greater than linear, which may imply a range of low susceptibility rather than a single cut-off dose.

The present study was carried out to evaluate the interaction analysis and antiulcerogenic activity of hydroalcoholic leaves extract of Salvia fruticosa leaves against ethanol induced gastric ulceration. Phytochemical and acute toxicity studies were carried out with standard methods. The docking studies performed using the CHARMm algorithm between 6YLU and phytoconstituent. Ulcers are induced in rats by administration of ethanol (1ml/kg, p.o.). One hour prior to ethanol administration, the various groups are treated with Salvia fruticosa extract (250 and 500mg/kg) and standard ranitidine (200mg/kg). A phytochemical study, shows the presence of various phytochemical constituents, while acute toxicity studies found no sign of toxicity. Results of docking studies showed two molecules rosmerinic acid (-54.1556kcal/mol) and stearic acid (-45.8874kcal/mol) showed higher affinity than standard drug. Treatment with extract at dose of 250 and 500mg/kg showed significant reduction in the ulcer score and ulcerative index, when compared to the standard drug Ranitidine.

Logic in tolkāppiyam (chapter of the book)
Authors: Selvamony Nirmal
Published: March 2023

Tolkāppiyam shows us that logic had an important place in the primal society (known as tiṇai). Such primal cultural practices as “tarukkam,” “vākai,” analogical reasoning, the use of the criteria of knowledge (“aḷavai”) in premarital life situations and in oral texts (such as mutumoḻi and kāṇṭikai), and also the primal social institution, namely, the assembly (avai) where public debates were held, were all part of the philosophical tradition of this society. Such philosophy embraced logic, which had rhetorical as well as epistemic functions. If rhetorical logic was persuasive (as in tarukkam) and contestatory (as in vākai in combat and in the assembly), epistemic logic (aḷavai) was validative. In fact, early Tamil logic was a complex discipline not easily distinguishable from philosophy (especially, epistemology and ethics) and rhetoric.

Guaranteeing trade in a severe crisis: cash collateral over bank guarantees
Authors: Kotidis Antonis , MacDonald Margaux , Malliaropulos Dimitris
Published: March 2023

Banks guarantee international trade through letters of credit. This paper analyzes what happens to trade when the critical role of banks as trade guarantors is compromised. Using the case of the Greek capital controls in 2015, the events around which led to a massive loss of confidence in the domestic banking system, we show that firms whose operations were more dependent on domestic banks suffered a steep decline in imports and, subsequently, exports. This operated through letters of credit, which during the capital controls period had to be backed by firms’ own cash collateral rather than the bank guarantee. As a result, cash-poor firms imported relatively less. Public intervention to guarantee transactions is shown to help mitigate some of the decline in imports.
Public Perception of the Hungarian Local Government Reform
Authors: Badó Attila , Feleky Gábor
Published: March 2023

Following a change of government in 2010, the Hungarian local government system underwent a period of significant transformation. The question of how it is viewed and the effects it may have are currently being debated. The centralising effort of the government had already become clear beyond a shadow of a doubt before the adoption of the Cardinal Act or the Fundamental Law (2011) itself. This was followed by the steps of the local government reform, which transferred many local government powers to the state. Municipalities lost influence over local public education institutions, municipal hospitals and many other areas. In this situation, where there was a significant loss of influence by local elites, it became an interesting question to what extent this changed society’s relationship with local government. Our comprehensive research has conducted a number of quantitative and qualitative studies to answer this question. Between 2016 and 2018, our research group had the opportunity to conduct four empirical studies to assess knowledge, attitudes and opinions related to local government. This paper presents and interprets the results of this research, and an important area of public attitudes towards local government, in particular with regard to the division of responsibilities between the state and municipalities.
Working Life During the Pandemic: Experienced Changes and their Implications for Occupational Well-being among Employees in Switzerland

Authors: Urbanaviciute Ieva , Gander Fabian , Massoudi Koorosh
Published: March 2023

The COVID-19 pandemic has brought unprecedented changes to numerous aspects of work such as working conditions, workload, income, nature of duties, or work-home balance that may eventually pose significant risks to employee well-being and career development. Using a person-centred approach, we examined how these changes cluster together, defining the experiences of different employee sub-groups. We then compared these groups regarding their background characteristics and selected aspects of occupational well-being (i.e., job satisfaction, job insecurity, turnover intention, work engagement, and exhaustion).
A sample of professionally active adults (N = 600; 55% women) completed a baseline cross-sectional survey, while a subsample (n = 426) further responded to brief daily questionnaires, reporting their job satisfaction, engagement, and exhaustion over a course of five workdays.
Results suggested three different patterns (i.e., latent classes) of pandemic-related changes at work. They characterized workers who experienced a strong decline in their workload and income (‘precarious’), those who experienced an increase in workload and a change in the quality of working conditions (‘challenged’), and those whose work situation was mostly unaffected (‘status quo’). These worker groups differed regarding their personal and professional background as well as occupational well-being outcomes. Those more strongly affected by the pandemic (the challenged or precarious pattern) were more likely to show initial background vulnerabilities, while those in the status quo group were more likely to benefit from working from home and reported the least detrimental outcomes. We discuss the implications of these findings within the conservation of resources and career sustainability frameworks.
Um olhar sobre a (re)construção de objetos de discurso no texto dissertativo-argumentativo
Authors: Silva Vitor Emmanuell Pinheiro da , Silva Wellington Barbosa
Published: March 2023

Este artigo objetiva investigar a (re)construção de objetos de discurso, isto é, referências textuais que podem ser construídas, reativadas e retomadas ao longo de um texto, em redações produzidas por alunos do Programa Pré-Enem, projeto de extensão da Universidade Estadual de Alagoas (UNEAL), em que alunos da graduação ministram aulas voltadas ao Exame Nacional do Ensino Médio – ENEM. Por se tratar de uma atividade inteiramente dinâmica e construída na esfera social, os interactantes participam do processo comunicativo de forma a introduzir, reativar ou recategorizar referentes e ideias construídas em seus textos. Os passos metodológicos são voltados à revisão da literatura linguística no que diz respeito à referenciação, seleção do corpus da pesquisa, leitura crítica das redações e seleção de textos para amostragem e análise das redações escolhidas. Assim, compreendemos que nas redações estudadas, os sujeitos constroem seus textos com propósitos argumentativos nada inocentes por meio de processos de negociação.
