Revisiting the Military Expenditure-Growth Nexus: Does Institutional Quality Moderate the Effect?
Authors: Dada James Temitope , Awoleye Emmanuel Olayemi , Arnaut Marina , Al-Faryan Mamdouh Abdulaziz Saleh
Published: February 2023

The purpose of this study is to examine the moderating role and threshold level of institutional quality in the nexus between military expenditure and economic growth for a panel of 31 African nations. The results reveal that military expenditure negatively influences growth, while institutional quality positively affects growth. The interactive term of institutional quality and military expenditure significantly positively influence economic growth. However, the threshold level of institutional quality for military expenditure to translate into economic growth in the region is found to be 4.61 on an ordinary scale of 0–10, although most countries operate below the threshold point of institutional quality. The study concludes that strong institutional quality serves as important absorptive capacity for military expenditure to drive economic growth in the region.
Innexin-Mediated Adhesion between Glia Is Required for Axon Ensheathment in the Peripheral Nervous System
Authors: Das Mriga , Cheng Duo , Matzat Till , Auld Vanessa J.
Published: February 2023

Glia are essential to protecting and enabling nervous system function and a key glial function is the formation of the glial sheath around peripheral axons. Each peripheral nerve in theDrosophilalarva is ensheathed by three glial layers, which structurally support and insulate the peripheral axons. How peripheral glia communicate with each other and between layers is not well established and we investigated the role of Innexins in mediating glial function in theDrosophilaperiphery. Of the eightDrosophilaInnexins, we found two (Inx1 and Inx2) are important for peripheral glia development. In particular loss of Inx1 and Inx2 resulted in defects in the wrapping glia leading to disruption of the glia wrap. Of interest loss of Inx2 in the subperineurial glia also resulted in defects in the neighboring wrapping glia. Inx plaques were observed between the subperineurial glia and the wrapping glia suggesting that gap junctions link these two glial cell types. We found Inx2 is key to Ca2+pulses in the peripheral subperineurial glia but not in the wrapping glia, and we found no evidence of gap junction communication between subperineurial and wrapping glia. Rather we have clear evidence that Inx2 plays an adhesive and channel-independent role between the subperineurial and wrapping glia to ensure the integrity of the glial wrap.

SIGNIFICANCE STATEMENTGap junctions are critical for glia communication and formation of myelin in myelinating glia. However, the role of gap junctions in non-myelinating glia is not well studied, yet non-myelinating glia are critical for peripheral nerve function. We found the Innexin gap junction proteins are present between different classes of peripheral glia in Drosophila. Here Innexins form junctions to facilitate adhesion between the different glia but do so in a channel-independent manner. Loss of adhesion leads to disruption of the glial wrap around axons and leads to fragmentation of the wrapping glia membranes. Our work points to an important role for gap junction proteins in mediating insulation by non-myelinating glia.

Lot of research is being carried out to develop solar cells which are economical with higher efficiencies. Many nanomaterials have been explored to tackle this issue. In this paper we have been used pure ZnS and cobalt doped ZnS nanoparticles which were hydrothermally synthesized from single source precursors using TX-100 as surfactant. The prepared precursors and samples were characterized using FTIR, TGA, XRD and UVVisible. The crystallite size of the nanoparticles calculated from the XRD analysis have been found in the range of 20-25 nm. UV-Visible analysis at room temperature shows absorption peaks in the UV-region. The optical bandgap calculated using Tauc’s plot from the absorption data lies in the region of 3.2-3.5 eV. This study helps in understanding novel performance of Co-ZnS in comparison to pure ZnS nanoparticles for its use in solar cell applications due to increase in photocatalytic activity in visible region.

SUSTAINABLE INDUSTRY AND SUPPLY CHAIN - WHAT TO TEACH
Authors:   University of Stavanger, Norway, Frick Jan
Published: February 2023

How to teach students about development and sustainable operation of companies and supply chain are a complex task with several partly conflicting issues. Entrepreneurship business models are more different than sustainable business models for operation and maintenance, but they can be seen as complementary or two stages of industrial development: explore and exploit. Both are part of what can be described as Entrepreneurial Mindset. Teaching in collaboration with companies tells us something of how this may be done as experienced in course cases. Supply Chains are becoming more and more global even for SMEs. With increasing use of global Supply Chains together with increased volume and frequency, the activities and logistics in between main operations have become more important to ensure reliability and sustainable operations. And these are based on collaboration and communication between involved companies and agencies. Core issues in this are charges that determine cost involved together with custom clearance issues, delays, miscommunications, and unforeseen circumstances. The sustainable Supply Chain of tomorrow needs to be data-driven to achieve improvement. We need to go from customer data to customer benefit. It may be achieved by utilizing AI to improve decisions and reduce latency. A 3-stage roadmap for utilizing Entrepreneurial Mindset in teaching digitalization of sustainable Supply Chain is suggested.

There have been several recent concerns about the deteriorating state of Nigerian companies’ performance. Many investors in Nigeria over the years have accused the quoted companies of not doing enough to improve their performances. Researchers are concerned about the factor that affects performance as a result of this. Therefore, this paper examines the influence of stock liquidity on the financial performance of companies in Nigeria. Data used are sourced from the financial statements of selected companies and the fact book of the Nigeria Stock Exchange for the period between 2012 and 2019. Data are analyzed using both descriptive and inferential statistics. The empirical findings of this study confirm that liquid stock, proxied by the turnover ratio (TOR), greatly impacts the performance of companies in Nigeria. Sequel to this, this paper concludes that the degree of operational success of Nigeria’s corporate entities is commensurate with the liquidity status of their stocks.
Cross Border Migration as a Poverty Alleviation Strategy; a Comparative Study between Immigrants from Zimbabwe to South Africa and Mexico to United States of America
Authors:   University of Limpopo, Limpopo, South Africa, Malatji Thabiso Lucky
Published: February 2023

This paper maps out the strategy that both Zimbabweans and Mexicans use to migrate to their neighboring countries in order to alleviate poverty. Both South Africa and United States of America have witnessed an increase in a cross-border migration whereby illegal and legal migrants cross the border to find greener pastures in different parts of the countries. Limpopo shares the borders with Zimbabwe and in the United States; California, Arizona, New Mexico, and Texas share the borders with Mexico. The high flow of immigrants to South Africa from Zimbabwe and United States of America from Mexico is mainly caused by the economic hardships in their home countries. Most migrants are youth, both males and females, and adult males who left their families back home and came to South Africa and America to find work and be able to support their siblings and children back in Zimbabwe and in Mexico. This is a conceptual paper; therefore, the author identifies the gap and relies on what is already documented but not addressing the issues of migration and poverty. The study aims to show the similarities between the Mexican immigrants and Zimbabwean immigrants while looking at how poverty encourages international human mobility. Findings from the study demonstrate that poverty is a push factor to migration. A large number of people from poor countries migrate to countries with good economies and opportunities with the aim of being employed so they can support their families in their own countries and some even start businesses and investments.
Education and Economic Growth: ıs There a Role for Governance? a Comparison between MENA and OECD Countries
Authors:   IHEC Carthage Business School, Tunisia, Jaafra Mariem
Published: February 2023

The outcomes of education and growth are mixed. This paper revisits the debate on the impact of education on economic growth by focusing on the effect of governance. Our sample covers 13 countries in the Middle East & North Africa and 37 OECD countries during the period 1990- 2020. For a dynamic panel type model, we preferred the GMM estimation approach in order to appropriately verify the relevance of the supporting indicators. Our objective is to determine whether the effects of education and governance on growth depend on the level of development of the country. Our results show that good governance contributes to economic growth in OECD countries. Strong governance raises the level and quality of education of the population and stimulates growth. The governance system is still being built for the nations of the MENA region, and it has several flaws. These results have important policy implications. Governments in the MENA region must invest more domestic resources in education and raise the standard of their institutions by implementing good governance practices if they want to improve output. Economic performance is possible when the governing principles are applied strictly, severely, and effectively. The advancement of education and the achievement of economic prosperity require efficient governance.

The first documented cases of Coronavirus disease of 2019 (COVID-19) in Wuhan city (Hubei province, China) were caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), studies mention viral transmission is more common in indoor and poorly ventilated environments compared to outdoor environments or environments with abundant airflow. In this context, this research aimed to estimate, through a mathematical model by a Box-Behnken design, the time and occupancy required in a physical space to reach CO2 levels that exceed the risk level established as a safer condition of 700 ppm for SARS-CoV-2 transmission. According to the proposed mathematical model, it is possible to predict safe conditions. With this, it was found that natural ventilation is the best option to reduce CO2 concentration, considering the occupancy/m3 and time, allowing a constant airflow; the use of air conditioners to control the temperature in rooms without natural ventilation is suggested; notwithstanding, these types of equipment are not designed to reduce CO2 concentration. Thus, their use in rooms with open windows and doors leads to a shorter equipment lifetime, for this reason, its operation in special conditions, such as in rooms without natural ventilation should be considered.

Reflections on mathematical figures and engineering approaches in anthropology
Authors: Kelly José Antonio
Published: February 2023

Abstract This paper presents and discusses some examples of how mathematical figures and engineering approaches can be detected in anthropological theorizing and how a mathematical reading of certain anthropological theories is possible and sometimes fruitful. The paper proceeds in three steps: a comparison between experimental measuring and engineering “black boxing” as different ways of representing ethnographic reportage and anthropological theorizing; a discussion of feedback loops in anthropological theorizing; and a discussion of chaos theory and fractal geometry and some of their uses in anthropological writing. I finish by hinting at the fruitfulness of making allies across disciplinary boundaries given our anthropocenic predicaments and limitations in our cross disciplinary analogies.
Film, music and sensory experience: questions concerning a project to film participatory musical performances
Authors: Villela Alice
Published: February 2023

Abstract This text sets out to discuss questions arising from the work of filming Brazilian popular festivals, celebrations and rituals in which music-making involves a process of collective musical production, practices linked to what Turino (2008) has called ‘participatory music.’ By making music together, the participants take part in intense non-verbal social interactions that very often reach a collective climax or trace, an experience difficult to translate into words. How can film express and communicate this type of musical experience involving all the senses? Setting out from technical guidelines developed in a project to film participative musical performances for a documentary series, Taquaras, Tambores e Violas, the text aims to reflect on the potential of the audiovisual medium as an experiential mode that both apprehends the musical context and enables the spectator to access and discover the participatory performances depicted through the evoked experience and senses.
Proposal for estimating the punching shear load-carrying capacity of steel fibers reinforced concrete flat slabs
Authors: Dantas Lucas Guedes , Oliveira Leonardo Henrique Borges de , Santos Antônio Carlos dos , Trautwein Leandro Mouta
Published: February 2023

abstract: This paper proposes an adjusted function for estimating the punching shear load-carrying capacity of concrete flat slabs without shear reinforcement according to the Brazilian standard code. The Adjusted function considers the influence of the steel fiber content. Data from 68 steel fiber reinforced concrete slabs (SFRC slabs) were used, simulating the connection of flat slabs with square section columns. These slabs were obtained from a study conducted by 14 different researchers. The parameters used for the adjusted function were the fiber content and the compressive strength of the concrete. The adjusted function was obtained by curve-fitting. The result from the adjusted function shows a relation in the order of 1.3 between the experimental rupture load and the calculated load, a value close to that already obtained by the normative text when the calculation is for conventional concrete. This shows that the proposal presented here keeps the same level of security with a confidence index of 96% in comparison with other authors’ models presented in this study.

Podocyte-Parietal Epithelial Cell Interdependence in Glomerular Development and Disease
Authors: Bronstein Robert , Pace Jesse , Gowthaman Yogesh , Salant David J. , Mallipattu Sandeep K.
Published: February 2023

Podocytes and parietal epithelial cells (PECs) are among the few principal cell types within the kidney glomerulus, the former serving as a crucial constituent of the kidney filtration barrier and the latter representing a supporting epithelial layer that adorns the inner wall of Bowman's capsule. Podocytes and PECs share a circumscript developmental lineage that only begins to diverge during the S-shaped body stage of nephron formation–occurring immediately before the emergence of the fully mature nephron. These two cell types, therefore, share a highly conserved gene expression program, evidenced by recently discovered intermediate cell types occupying a distinct spatiotemporal gene expression zone between podocytes and PECs. In addition to their homeostatic functions, podocytes and PECs also have roles in kidney pathogenesis. Rapid podocyte loss in diseases, such as rapidly progressive GN and collapsing and cellular subtypes of FSGS, is closely allied with PEC proliferation and migration toward the capillary tuft, resulting in the formation of crescents and pseudocrescents. PECs are thought to contribute to disease progression and severity, and the interdependence between these two cell types during development and in various manifestations of kidney pathology is the primary focus of this review.

Objetive: The aim of this study was to determine the prevalence, demographics, and root configuration of C-shaped canals of mandibular molars by means of cone beam computed tomography in the population of the Metropolitan Region, Chile. Material and Methods: 912 molars (456 first and 456 second molars) resulting from the analysis of 228 mandibular CT scans were evaluated. The root configuration was established by means of a panoramic reconstruction and axial tomographic sections, classifying the presence and type of canals through the analysis of five sections or cuts along the root. Data were statistically analyzed using a 5% confidence interval. Results: Of the 912 molars analyzed, 70 were classified as C-shaped canals (7.68%), corresponding to 58.33% of those molars that presented fused roots. 95.7% of this root canal configuration was observed in lower second molars, occurring more frequently in females (n=45, 64.29%). 45.65% of the cases that presented C-shaped canals were bilateral and the most frequent configuration was C3 (n=401, 66.63%) according to the Melton classification. Conclusion: The C-shaped canals of the mandibular molars in the studied population were observed mainly in second molars, showing a clear prevalence among females and a high percentage of bilaterality. The presence of fused roots significantly increases the possibility of finding this type of root configuration.

The adsorption and photocatalytic activity of iron-containing metal-ceramic composites produced by the self-propagating combustion of aluminum ferrosilicon in nitrogen with the addition of metallic tantalum (0, 5, 10, 15 wt%) during oxidative degradation of pharmaceutical pollutants (chloramphenicol, metamizole, cinnarizine) under UV and visible light was evaluated. The phase composition of the composite materials was determined by X-ray diffraction and infrared spectroscopy. The morphological features and optical properties of the composites were investigated, and the band gaps of the semiconductors included in the ceramic matrix were determined. The acid properties of the surface of the composites were studied using pH-metry and the Hammett indicator. The correlation of the number of surface-active sites and adsorption of pollutants with the corresponding value of pKa was shown, and the mechanisms of adsorption were proposed. Optimal conditions for the oxidative degradation of chloramphenicol (~100%) under visible light were found: a composite (5% Ta) with the addition of H2O2 to combine heterogeneous catalysis with the homogeneous photo-Fenton system.

The results of experimental studies of analogs of columnar red sprites are presented. As is known, the development of sprites is due to the formation of cylindrical streamers at an altitude of 50-100 km from sea level. The velocities of a plasma diffuse jet (PDJ) obtained in a laboratory, which is an analogue of a sprite, were measured, and its emission spectra were recorded. Estimates are made of the magnitude of the reduced electric field strength in the PDJ at various distances from the electrodes initiating the discharge. It has been established that the shape and color of PDJ, which are also cylindrical streamers, at air pressures of 0.2-1.5 Torr corresponds to the color and shape of columnar red sprites. It is shown that the change in the color of diffuse plasma jets is associated with an increase in the reduced electric field.

Methods for controlling the power electron beam in a source based on a low-pressure arc discharge with layer stabilization of the emission plasma boundary are described. The control is carried out by the method of amplitude and latitude modulation within the duration of the beam current pulse with a time resolution of 10 μs at a submillisecond pulse duration. Two ways to control the power of the electron beam are implemented: the first one is based on changing the concentration of the emission plasma by modulating the arc discharge current, the second method uses grid control (the mode of operation of the plasma triode) at the constant discharge current. Simplified diagrams of the power supply sources of the discharge and intergrid control voltage, typical oscillograms of the main currents of the discharge system, a graph of a quick-acting power change, and a control characteristic of a plasma triode are presented.

The spectral characteristics of the cathodoluminescence of several synthetic nitrogen-containing diamond samples upon excitation by an electron beam with an energy of up to 300 keV in the temperature range of 80-800 K have been studied. Data on temperature quenching of the cathodoluminescence of diamond samples with various impurity-defect compositions at elevated temperatures (more than 400 K) have been obtained. It has been found that the rate of thermal quenching of NV0 centers is higher than that of NV centers at temperatures of ~500 K and higher.

Using the electron-ion-plasma additive method, the HEA film formed on a substrate (AISI 304 steel) was saturated with boron by vacuum deposition from gas-metal plasma created by simultaneous independent vacuum arc discharge evaporation of the cathodes of selected elements in the plasma-assisted mode. Doping of HEAs with boron and oxygen atoms, as well as with substrate atoms has been revealed. It is shown that the multicycle modification of the HEA film is accompanied by the formation of a nanostructured multiphase layer with a thickness of 5-7 µm, containing inclusions of borides and oxides of the HEA chemical elements and the substrate. It has been established that the modification of the HEA film leads to a multiple (by 18 times) decrease in the wear parameter of the material.

The paper presents the results of spectral and cardinal characteristics of AlGaN/GaN and InGaN/GaN LED heterostructure pulsed cathodes and photoluminescence grown on sapphire by metal organic vapor phase epitaxy are introduced. The effects of high current electron beam energy density on the luminescence spectra and amplitude characteristics of heterostructures are studied. The spatial distribution of fluorescence characteristics on the wafer surface was studied. It is found that in InGaN/GaN heterostructures, the maxim shifts of stimulated cathodoluminescence spectra measured at different points of the sample. This result is due to the changes in the composition and thickness of the quantum dimensional active region, and this change is not due to the ideality of the plate growth process.

The text is an authorized translation of Ernst Gombrich’s lecture first published in the Journal of Art Historiography (2022). The lecture explores the ways the history of art is and should be taught at art academies. It, too, reveals the prejudices towards history as a discipline and the shortcomings of traditional ways of teaching it. At the end, Gombrich summarises his own views on the subject and suggests possible options for teaching art history.
INNOVATIONS IN DATA EXCHANGE FOR LAW ENFORCEMENT TASKS
Authors: Krutova Erika
Published: February 2023

Information systems are becoming increasingly important in the functioning of law enforcement authorities. In addition to border control in the area, the exchange of information between national competent services is of particular importance. This process is ensured in the European Union through a number of tools, some of which the Schengen Information System, Passenger Name Record, the Europol’s Secure Information Exchange Network Application are. Legal instruments such as the Prüm Decisions and the Swedish Initiative have been adopted to reduce legal barriers and accelerate the exchange of information between national competent services. However, criminal threats force to reassessment of the effectiveness of existing cooperation and for even more targeted action. Although existing resources and technological capabilities allow information to be searched online, to perform cross-checks for match detection and rapid data exchange, modern options have not been fully implemented yet. The aim of this article is to analyse the existing instruments for information exchange and to assess the novelties of the Directive of the European Parliament and of the Council on information exchange between law enforcement authorities of Member States, repealing Council Framework Decision 2006/960/JHA. Empirical research methods were used in the study. The author of the study comes to the conclusion that the implementation of the Directive requires significant improvements in national regulation.

Player models are an essential tool used by Experience Management AI when adapting a game experience for specific players. This research develops and explores approaches to player modeling in both single-player and multiplayer contexts that rely on the use of Multi-Armed Bandit (MAB) techniques. In addition to proposing advancements for MAB techniques to meet the challenges of this particular context, we extend our investigation into their use in more general and traditional applications, such as node selection policy in Monte Carlo Tree Search. We evaluate our approach toward both cooperative and competitive goals via simulated and real human user studies as well as adversarial board games.
Celebraciones cívicas en la construcción de un estado: Campeche, 1857-1862
Authors: Sánchez Ulloa Cristóbal Alfonso
Published: February 2023

Este artículo aborda las celebraciones cívicas realizadas en la ciudad de Campeche entre 1857 y 1862. El objetivo es conocer el papel que dichas celebraciones desempeñaron en el proceso de construcción del estado. Se propone que estos actos fueron parte de la cultura política de quienes protagonizaron dicho proceso, por medio de los cuales buscaron legitimar su autoridad, justificar la emancipación de Campeche y mostrar que el estado existía, de facto, desde 1858, aunque no contara con el reconocimiento del gobierno mexicano. Este caso permite reflexionar sobre el uso de las celebraciones cívicas en la política de mediados del siglo XIX en México, en un contexto de formación de nuevas entidades políticas. Y, por otro lado, permite observar algunas de las transformaciones que las Leyes de Reforma originaron en las prácticas celebratorias, en un sitio que se mantuvo al margen de la guerra civil de 1858-1861.
