Causality relationship between bank indices: an application on selected countries
Authors: Sezal Levent , Serbetci Ahmet
Published: February 2024

Purpose- If price volatility in one stock exchange has an impact on other stock exchanges, this is called volatility spillover effect. Along with volatility, the change in returns in one stock exchange can also affect other stock exchanges in the short term. This situation is called interconnectedness, co-movement and furthermore, interdependence of stock markets. Therefore, this study aims to investigate the causality relationship between the bank indices of the 5 countries with the highest income (USA, China, Japan, Germany and India) in 2022 according to IMF data.
Methodology- In the study, the daily frequency data set between 04/01/2018 -16/11/2023 was used. In the analysis phase, firstly, ADF and PP unit root tests were applied to determine whether the variables are stationary or not. Causality relationships between variables were tried to be determined by Granger Causality test.
Findings- When the relationship between the bank indices of the 5 major economies subject to the research is analysed, a granger causality relationship was found between DAX variable and FTSE, TR INDIA and NIKKEI, between FTSE index and NASDAQ and NIKKEI, between TR INDIA and NIKKEI.
Conclusion- Ülke borsası arasında bağımlılık ilişkilerinin kendini göstermesi ve konjonktür dalgalarının bu sürece etki etmesi, finans piyasasında alınan kararlar ile ortaya çıkan etkilerin diğer finans piyasasına etki edebileceğini ve bu doğrultuda da yatırımcı hareketlerini yönlendirebileceğini göstermesi bakımından oldukça önemlidir.

Authors: Bumin Mete , Ertugrul Aysegul
Published: February 2024

Purpose- The inclusion of companies in the BIST Sustainability Index and the disclosure of sustainability scores provide not only benefits in terms of making companies’ sustainability practices better known by stakeholders and the public, but also may increase stock returns. Therefore, this study aims to analyse the relationship between sustainability scores and financial performance of companies in the BIST Sustainability Index.
Methodology- In order to analyse the relationship between the sustainability scores of 62 companies in the BIST Sustainability Index and their financial performances, the sustainability scores of the companies and the companies' firm value, return on assets and stock rate of return as the financial performance indicators is examined by multiple regression analysis method over the data of 2022.
Findings- A negative relationship was found between the sustainability scores of the companies and the firm value, while no significant relationship was found between the sustainability scores and the other financial performance indicators, namely return on assets and stock rate of return.
Conclusion- The reason for the negative relationship between the sustainability scores of the companies and the firm value may stem from the investors’ perception that the environmental investments to be made by the the company will increase the company's costs, which will have a negative impact on the company's financial statements and thus on the stock return.

Handling missing values in mixed panel data: a comparison of different techniques
Authors: Ekinci Cumhur , Hakkoz Mustafa Abdullah , Kiran Unsal , Seker Sirma
Published: February 2024

Purpose- The purpose of this study is to compare the success of alternative data imputation techniques with missing data. The study distinguishes itself from the rest of the literature by proposing an appropriate technique for mixed data on financial performance and environmental, social and governance (ESG) metrics of companies. In addition to simple imputation techniques, we also use machine learning techniques that allow working with more complex data.
Methodology- We first employ ad-hoc methods such as mean, median, mode, constant, most frequent and regression imputation. In what follows, we handle multivariate imputation techniques such as multiple imputation by chained equations (MICE). Finally, we run imputation methods with machine learning (ML) classification such as K-nearest Neighbor (KNN), Ridge and Random Forest. To consider the assumptions of missing data, we first check the normality of the variables with Kolmogorov-Smirnov test and employ Rubin’s classification technique that defines the relationship among variables with the probability of missing data. The success of imputation techniques applied to missing data changes when the missing data are classified with Rubin’s technique according to randomness. Consequently, we apply listwise deletion at various levels and alternative data imputation techniques. We then compare their performances. The raw data contain parametric as well as categorical variables (binary and others). Among these are time-series (yearly) financial series such as sales and total assets obtained from financial statements, ESG scores as well as float ratios for firms from several countries and industries. Imputation is done randomly on a sample varying from 5% to 30% of the dataset and results are compared to true data based on accuracy or other measures such as root mean square errors (RMSE) or mean absolute percentage error (MAPE). Several robustness checks have been performed to supplement the analysis.
Findings- Results show that ML methods such as KNN have a superior performance than others. Moreover, when multidimensional nature of the data is taken into account, the prediction performance improves. Hence, an optimality can be reached based on parameters.
Conclusion- Based upon the analysis, we conclude that the selected imputation technique and how it is employed matter to attain a higher accuracy and a better prediction of the missing values on selected mixed panel data in finance.

Molecular inclusion encapsulation of orange essential oil: Effect of the drying method on physical, chemical, structural characteristics and stability
Authors: Huaman Lopez Malory , Villanueva-Quejia Elizabeth , Nolazco-Cama Diana
Published: February 2024

Previous investigations suggested the orange essential oil as antimicrobial and natural antioxidant; however, the high volatility and sensibility due to extern factors are imitating its applications. Thus, the encapsulation is an ideal alternative of protection for essentials oils and the molecular inclusion has greater advantages compared to others, but the drying method and temperature can influence its characteristics and stability. Therefore, the orange essential oil was microencapsulated into beta-cyclodextrin (β-CD), and was evaluated the effect of drying by stove, lyophilization and atomization (160, 180 and 200 °C) on humidity, water activity, encapsulation efficiency, yield, and stability (82% relative humidity for 36 days). The microparticles were analyzed by Fourier transform infrared spectroscopy (FTIR) and scanning electron microscope (SEM). The best drying method was lyophilization achieved an encapsulation efficiency of 97,35%, humidity 1,76%, water activity 0,54, and low hygroscopicity 0,20%. The results by FTIR found the formation and loss of some bonds between orange essential oil and beta-cyclodextrin, probably by effect of temperature. The lyophilized microparticles presented best stability with final efficiency of 52,53% with low humidity and water activity. This study makes it possible to establish the best drying method in cases of molecular inclusion, which may be useful in future applications when developing products.

Lenguajes de la Fotografía
Authors: Leal Garcia Aurora
Published: February 2024

El presente artículo trata de reflexionar acerca de algunas formas de aproximarse a la fotografía. Así como sucede con el texto, la fotografía es también un medio que favorece la creación, el descubrimiento de mundos o situaciones imaginadas. El acto de fotografiar conduce a distintas formas de pensar, de observar, de mirar y también de expresar simbólicamente. Su realización no debería centrarse únicamente en el resultado final, es decir, la imagen deseada, sino también en el proceso, los pasos previos que permiten descubrir otras representaciones, nuevos pensamientos que favorecen la selección de unas u otras imágenes de formas diversas. También las repeticiones, eliminaciones, búsquedas o hallazgos a veces imprevistos son sustancias del pensamiento fotográfico. Se destaca la importancia de descubrir en la fotografía aquello que queda implícito, aquello que no se aprecia visualmente, no sólo para quien realiza la fotografía sino también para quien la contempla. Finalmente se presentan cuatro pares de fotografías sin título alguno, cuya posible relación dos a dos invita a ser contempladas de forma simbólica.

Authors: Duran-Bonavila Silvia , Rodriguez-Gomez Alicia , Becerril-Galindo Marta
Published: February 2024

Grade repetition is an issue with important educational implications. This study analyzes the effect of cognitive variables, socio-economic status, as well as the interaction of socio-economic status with  ethnic origin, on the probability of not repeating. Data were collected to calculate socioeconomic status using the Hollingshead Socioeconomic Index, and the following tests were administered to collect information on cognitive variables: the Primary Mental Aptitude Test (PMA), the Raven's Progressive Matrices Test, and the Wechsler Intelligence for Children Information Scale (WISC IV).  The sample consisted of 664 students of Compulsory Secondary Education (ESO), Baccalaureate and intermediate and higher vocational training. The results confirm the predictive power of socioeconomic status. With regard to cognitive variables, significant results were only obtained when the WISC-IV Information Scale was taken as a predictor, this measure being related to crystallized intelligence. The influence of the origin of the students did not yield significant results. There is a clear need for a debate and a rethinking of the issue leading to the identification of new strategies to reduce grade repetition and its negative effects.
When Does Automation in Government Thrive or Flounder?
Authors: Estevez Elsa , Janowski Tomasz , Roseth Benjamin
Published: February 2024

Government organizations worldwide are harvesting the transformative potential of digital technologies to automate interactions with citizens, businesses, and each other. Automation can bring benefits, such as an increase the efficiency of government operations, quality of government decisions, and convenience of governmentcitizen interactions. It can also produce adverse outcomes, such as compromising social value for economic gains, misjudging citizen circumstances, and having to compensate for the effects of algorithmic errors. This publication delves into the implications of automation and how to implement initiatives that increase its benefits and manage its risks. Specific questions include: (i) how to identify areas of public policy and public services that are most apt for automation; (ii) what questions, regarding potential benefits and costs, should governments ask before embarking on a process of automation; (iii) how governments should monitor the benefits and costs in the process of automation and establish whether automation has had the desired impact; and (iv) how to organize and manage automation efforts. The authors explore these issues through 12 case studies from 8 countries (Argentina, Chile, France, Norway, Paraguay, Singapore, Spain, Sweden), the European Union, and 7 government sectors (administration, border control, finance, justice, procurement, registry, and welfare). Each case study identifies the problem automation was designed to resolve or service it was designed to deliver; potential benefits and costs of automation that were relevant in each context; and examples of how automation was implemented to reduce costs and monitored to ensure high impact without unintended negative consequences. The cases guide the formulation of a taxonomy of benefits and risks of government automation initiatives and the four broad factors that government organizations should consider when aiming to realize the benefits and manage the risks of such initiatives: institutional readiness, human capacity, process innovation, and whole-of-government approach. It also presents strategies for implementing the factors and discusses how they help produce public value.

The objective of this research work was to evaluate the antimicrobial effect of 2 oil sources against Staphylococcus aureus and Fecal Coliforms. For the oil extraction, the steam drag method was applied where 5000g of sample was used (muña, Eucalyptus leaves), in which the yield presented: muña 50ml = 0.9268%, eucalyptus 52ml = 0.9717%, a Physicochemical characterization whose result was: in muña oil: peroxide index: 0.75 (Meq / Kg), Iodine index: 6.87 (IV), Acidity index: 1.78 (% FFA), Refractive index: 1.486 (n), density: 0.898 (Kg / L). In eucalyptus leaves: peroxide index: 0.68 (Meq / Kg), Iodine index: 8.08 (IV), Acidity index: 1.82 (% FFA), Refractive index: 1.495 (n), density: 0.845 (Kg / L). Inhibition halos were determined in millimeters (mm), with muña oil in dilutions at 25, 50 and 75% against Fecal Coliforms, where it was at 25%: 9.7950mm, 50%: 10.7467mm, 75%: 13.2700 mm, against Staphylococcus aureus, 25%: 9.9600mm, 50%: 10.7408mm, 75%: 13.1533mm; with dilution of Eucalyptus essential oil against Fecal Coliforms at 25%: 12.0983mm, 50%: 13.2900mm, 75%: 14.5875mm; then against Staphylococcus aureus in 25%: 11.7200mm, 50%: 13.5608mm, 75%: 14.3767. It was possible to establish the inhibitory effect in 2 sources of oils against Fecal Coliforms and Staphylococcus aureus, for which it is concluded that the more dilution of the oil, more microbial inhibition, these species have their respective active principles such as monoterpenes, alcohols, ketones and terpenic oxides that prevent microbial growth.

Published: February 2024

Potato (Solanum tuberosum L.) is a crop of great importance worldwide due to its high nutritional value and its adaptability to different climatic conditions. In Peru, it is one of the main crops in terms of production and consumption, with Junín being one of the departments with the highest production. The aim of this research was to evaluate the effect of water stress on the growth and yield of commercial potato cultivars. Four irrigation frequencies (field capacity, every 7, 14 and 21 days) and five commercial potato cultivars (Canchán, Yungay, Wankita, Serranita and Shulay) were evaluated, distributed in a completely randomized design with a 5x4 factorial arrangement, with five replications. It was installed under greenhouse conditions and seven variables (plant emergence, plant height, number of stems, number and weight of tubers, transpiration rate and dry matter) were evaluated. The results showed statistical differences in all the variables evaluated. It was found that the Canchán cultivar with irrigation frequency every 21 days was more tolerant to drought with an average rate of 0.69 ml, the maximum permissible irrigation limit in greenhouse is every 14 days. The highest number of tubers was observed in the Wankita cultivar with 29.8 tubers under a drought stress of 14 days. The highest tuber weight was obtained with the Yungay cultivar at field capacity with 0.438 kg per plant. It is concluded that water stress influences potato growth and production.
Impact of Flow, Heat and Mass Transfer of Newtonian and Non-Newtonian Nanofluids Flow over a Non-Darcy Stretching Sheet in the Context of Fuel Applications
Authors: C. Manoj Kumar  , Benazir A. Jasmine
Published: February 2024

The study of flow, heat, and mass transfer of Newtonian and non-Newtonian nanofluid over porous media holds paramount significance in the context of fuel industries, contributing to enhanced efficiency, reduced emissions, and sustainable energy production. This investigation provides a concise overview of the critical role played by porous media in various aspects of the fuel sector. In the oil and gas industry, porous reservoir formations exhibit complex fluid dynamics characterized by non-Darcy flow, influencing recovery rates of hydrocarbons. Understanding the relationship between flow, heat, and mass transfer within these porous reservoirs is essential for reservoir engineers and fuels the quest for maximizing resource extraction. The Sisko nanofluid model is one of the most sought-after mathematical model which prophesies the interesting features of Newtonian and non-Newtonian (dilatant and Pseudoplastic nature) fluids. In contemporary years, a new class of non-Newtonian fluids with nanoparticle suspensions are gaining popularity as it is beneficial in enhancing thermal efficiency in several applications such as warming/cooling of home appliances and micro-electronics etc. However, the modeling on this class of non-Newtonian fluids is limited. In light of above, this work predicts the stream, heat and mass transmission behavior of nanofluids using Sisko fluid model. Stretching sheet with porous medium has been used for this study with addition with magnetic field, thermal radiation, Brownian motion and thermophoresis. The non-linearity issues in this fluid flow are addressed in the prevailing work using suitable similarity transformations. The non-linear dimensional coupled P.D.E are converted into nonlinear dimensionless coupled O.D.E. These equations are solved using MATLAB by implementing four-stage Lobatto IIIa formula. The impacts of copious physical parameters of flow, energy and mass transfer insights are discussed. From the outcomes of current work, it is perceived that increasing the perviousness of the porous medium reduces the fluid mobility. Further, for increased values of Prandtl number the heat transfer coefficient increases ensuing in more heat transfer. Flow, heat, and mass transfer over porous media are integral to fuel industries, influencing resource extraction, energy conversion, and product quality

In light of its potential health benefits, including as improved gut health and management of the gut microbiota, herbal extracts have witnessed a major increase in demand as prebiotics in recent years. Many studies have demonstrated that polyphenolrich herbal extracts can work as prebiotics by encouraging the growth of beneficial gut flora. Unfortunately, the limited solubility and stability of these herbal extracts, as well as their susceptibility to breakdown in the gastrointestinal system, can limited their bioavailability and efficiency. To address these limitations, the integration of metal nanoparticles has emerged as a promising strategy for the efficient delivery of herbal extracts, affording heightened bioavailability and precise targeting of the gut microbiota. In this paper, we present current breakthrough in metal infused nanoparticle-based assessment of herbal extracts as efficient prebiotics, with an emphasis on formulation, characterization, and biological activity. The integration of metal nanoparticles into polyphenol-rich herbal extracts represents a cutting-edge approach to enhancing the prebiotic properties of these compounds. Metal-infused polyphenol-enriched phyto-fabricated nanoparticles hold great promise for improving gut health and modulating the gut microbiota, offering innovative solutions to address the limitations associated with traditional polyphenol delivery. Furthermore, extracts of polyphenol-rich medicinal herbs such as rosehip flower, hibiscus flower, mango bark, bamboo stem, green tea, pomegranate, and dhataki flower have been investigated to assess the viability of employing these phyto generated metal infused nanoparticles as a potential prebiotic
Structural, Electronic and Magnetic Properties of Silicene Functionalized with 4d TM Atoms

Published: February 2024

The experimental realization of silicene has ignited a great deal of interest in researching its properties for utilization in device applications. Silicene is composed of a lattice of silicon. As a result, it can be integrated with contemporary circuitry structures, which are predominantly silicon-based. Therefore, investigating its characteristics, especially those of the bandgap, is pivotal. In the present work, the density functional theory approach is employed to examine the structural, electronic and magnetic characteristics of free-standing silicene doped with 4d Transition Metal (TM) atoms. Modelling is done for a 4x4 silicene supercell with a single vacancy. The resulting structure is, thus, doped with 4d transition metal atoms. Doping results in lattice distortion, as evidenced by the variance in Si-TM bond length relative to Si-Si bond length. The shortest bond length is noticed in the instance of Ru doping, thus demonstrating its strongest bonding with Si atoms. Doping causes the structure to become increasingly deformed, as proved by the elevation in buckling height as well. Except for Zr, Ru and Pd, which exhibit semiconductor behaviour, the 4d TM doping in silicene results in metallic characteristics as the bands cross the Fermi level in the majority of the configurations discussed here. A narrow band gap with a range of 2.1 to 252 meV is produced by doping silicene with Zr, Ru, and Pd. Magnetism is demonstrated by Nb, Mo, Tc, and Rh-doped structures, whereas the other structures are nonmagnetic. The presence of magnetism in these structures is primarily due to contributions from Si-3p, TM- 4d/5s orbitals, and their hybridization.

Published: February 2024

The transient thermal performance of a fully wetted longitudinal permeable fin under natural convection, radiation, and internal heat generation has been studied in the present problem. Due to variation of fin thickness with respect to fin length, it is possible to obtain different fin profiles such as triangular, convex and rectangular profiles. Here, the diverse profiles of the fin have been considered for the examination and Darcy’s model was implemented to investigate the porous nature of the fin. The governed partial differential equation has been solved by applying finite difference method. The influence of dimensionless parameters on the transient thermal profile as well as the heat dissipation rate of the three types of fins, has been graphically illustrated and interpreted physically.

This Research article discuss about the study of performance analysis. This system is a combination of refrigerator and Atmospheric Water Generator (AWG). The purpose behind integrating two devices is to get benefit of both products together, refrigerator will act as a domestic refrigerator plus the atmospheric water system will generate the fresh distilled water to drink. This system is designed to generate a water of 20 liters per day. Also, it is designed in such a way that, this AWG can attach with various capacity is the refrigerator. Performance evaluation of this system is done with the help of computational fluid dynamics. Fluent module is used in ANSYS software. Various levels of parameter are evaluated, variables considered in the study were Relative humidity, velocity of air in AWG heat exchanger, and temperature of air. The output parameters evaluated like water generation capacity of AWG, Coefficient of Performance (COP) of AWG and refrigerator and heat exchanger efficiency. The results of CFD shows positive results as per design. 24th case has given highest COP 1.26. General, range of COP lie between 1.127 to 1.260. COP of Standard Refrigerator remain between 1.437 to 1.593. Also, it means COP of other two cases are more. As far as COP of Refrigerator concern, COP with AWG is heist i.e. 1.91. But it cannot be clearly state that, COP with AWG is more than COP without AWG.
‘Midlife Crisis’ and the scramble for fresh personal purposes amongst middle-aged men
Authors: Matewe Bothwell
Published: February 2024

The universality of the midlife crisis has cost so many middle-aged men, with so many men rebooting and restarting their lives in the scramble for a fresh personal purpose. The researcher’s inquisitiveness about the experiences of middle-aged men in an identified community in Masvingo, Zimbabwe ignited the study. However, little research has been carried out in this nation concerning the subject under study. The study aimed to understand the psychological and social experiences of middle-aged men and how midlife crises can facilitate marital instabilities and a drastic change in social life. A narrative biography was obtained from the seven men in-depth interviewed. The purposively selected participants were between the ages of 35 and 45. Confirmation of the different studies that have been carried out in the West, many middle-aged men experience a lot of psychological challenges, including depression, stress, insomnia, and others. The study discovered that the escalation of divorce rates is rooted in the challenges associated with the midlife crisis. Many middle-aged men are not aware of marriage counseling, with quite a number less or not knowledgeable about the existence of psychological services. The study exposed the need for educational campaigns and midlife crisis awareness to the populace.
