Authors: Писаренко Г. , Войналович О. , Майло А. , Писаренко С.
Published: March 2023

It has been shown that to study the kinetics of operational damage to materials and structural elements, it is necessary to develop modern means and methods for diagnosing damage occurring in laboratory samples and structural elements. In this paper, in order to determine the deformation state of the surface layer of a structural material, using austenitic steel samples as an example, we used the method of optical measurement of microplastic deformation, which is based on the correlation between the energy of a coherent light source reflected by the surface of a metal polycrystal and the amplitude of microplastic deformation of the deformed surface. According to this method, the local area of the material sample surface under investigation is irradiated at certain stages of loading with coherent light beams with a wavelength that corresponds to the scale of localization of microplastic deformations of the sample surface. An optical system is used to generate an image of the speckle-modulated beam, which has the parameters of the deformed surface relief. As a measure of the depth of the deformation relief, the integral value of the image brightness intensity parameter is used as the ratio of the number of light pixels to the total number of pixels in the specklegram image. As a result of the analysis of the statistical parameters of the specklegram, which correlate with the characteristics of the state of microplastic deformation of the surface of austenitic steel samples, the characteristic parameters of the scattered damage to the structure of discrete deformations of the surface of a metal polycrystal were determined. On the basis of the experimental data obtained, the regularities of the influence of static and cyclic deformation on the shape of the distribution of discrete surface properties were revealed. In particular, as a result of analyzing the statistical characteristics of the correlation diagrams, a linear dependence of the parameters of the distribution of discrete properties of the deformed surface relief on the loading factor was obtained.
Constructing a meridian for a given motion of a particle on a surface rotating around a vertical axis

Published: March 2023

The article deals with the design of a surface of rotation, which is reduced to finding its meridian according to specified conditions. These conditions are the nature of the particle's motion on the inner surface when it rotates around a vertical axis. The absolute motion of a particle is formed from the ratio of the rotational motion of the surface and the relative motion (sliding) of the particle on the surface. Classical examples of such motion are the motion of a particle inside a vertical cone rotating with a constant angular velocity around its axis, as well as the special case when the angle of inclination of the cone's constituent parts is zero and it turns into a horizontal disk. The meridian curve can be given by an explicit equation or by parametric equations as a function of the independent variable. In this article, we consider the case when the meridian of a surface of rotation is given by parametric equations as a function of time. This makes it possible to compose a differential equation of motion of a particle in which all dependencies are functions of time. These dependencies need to be found from the compiled differential equation of motion of the particle.

When a particle hits a surface, it starts to slide along it, describing a curved trajectory. Taking into account the rotational motion of the surface, the absolute trajectory is found. The first derivative of its length in time gives the absolute velocity, and the second gives the absolute acceleration, the expression of which includes the unknown functions describing the meridian. The differential equation of motion is written in projections on the three axes of the Cartesian coordinate system. The system of three equations includes four unknown functions: two equations describing the meridian, the dependence of the angular velocity of the particle sliding, and the surface reaction. To solve the equation, the number of unknown functions must be reduced to three. To do this, we define one dependence. This approach leads to special cases, one of which is the movement of a particle on a horizontal disk rotating around a vertical axis. A specific example is considered and a meridian curve is constructed as a result of numerical solution of the equations, provided that the particle inside the surface rises upward with a constant given speed.

Published: March 2023

One of the main ways to improve the efficiency of agricultural machinery operation is to study technical readiness when planning the main stages, objects and scope of maintenance and repair work. Existing systems of maintenance and repair of machinery do not fully take into account the operating conditions characterized by a certain group of factors. The problems of an individual approach to assessing the technical condition and promptly adjusting the modes of maintenance and repair of machines in the conditions of their operation remain relevant.

The purpose of this article is to study the impact of operational factors on the technical condition of agricultural machinery in the process of its use. For example, the object of research is the means for preparing and distributing feed (MPF) used in animal husbandry. The paper applies the method of a priori ranking and the methodology for assessing the non-randomness of expert agreement. A classification of operating conditions is presented, taking into account their influence on changes in the technical condition of the feeding and dispensing equipment. From the set of presented conditions, the factors affecting the operation of air defense systems are identified.

Based on the results of the expert survey, data were collected for a preliminary ranking of the factors. For each factor, the sum of the ranks of all experts was determined. Four factors were identified that have a predominant influence on the technical condition of air defense systems: reliability of the vehicle design; professionally important qualities of personnel; organizational and technological factors; intensity of operation and load on operating equipment. The concordance coefficient was used to estimate the degree of agreement among experts' opinions. The results obtained by a priori ranking can be considered satisfactory and adequate. The test of the hypothesis of non-randomness of the experts' agreement according to the Pearson criterion indicates the significance of the concordance coefficient, significant similarity and non-randomness. The results of the study of the influence of operational factors on the technical condition of air defense systems have been practically confirmed and used in production conditions.
Research on the rotary shearing machine
Authors: Хмельовський В. , Веселівський К.
Published: March 2023

The effectiveness of sheep shearing largely depends on the performance of shearers. Due to the mechanical energy of the machine, only the cutting of wool fibers occurs, and its movement on the surface of the animal's body is carried out by a person - a shearer. Highly skilled shearers use about 90% of its width when shearing fine fleeces with a wide-comb (b=76.8 mm), low and medium shearers use 50-75%. The most professional shearers usually work with narrow-grip combs (b=57.6 mm), because a narrow-grip comb has less resistance to the shearer's hand during shearing and allows the shearer to move the machine at a higher speed than a wide-grip comb. Thus, the performance of the shearer depends on the following factors: traction force - P, movement speed - V, operating time (duration of the work process) - t. Theoretical calculations have shown that at the maximum effort of the shearer, the optimal feed speed is 0.93 m/s, and the load on the shearer's arm should not exceed 30.6 N. An increase in the load on the shearer's arm of more than 30.6 N causes a decrease in the feed speed, and, accordingly, a decrease in productivity.

In the world practice of shearing sheep, there are two most successful technical solutions: a reciprocating shearer and a rotary shearer. The analysis of each of the options showed that the reciprocating shearer, if the technological parameters are not met, dramatically reduces the quality of work (increases the chaff content) and increases power consumption.

Chaff and overcuts are undesirable in the shearing process, and their total content in the fleece should not exceed 1%. While the latter depends on the qualifications of the shearer, the former mainly depends on the combination of geometric, design and technological parameters of the cutting apparatus and shearing machine.

Cutting wool with a rotational movement of the knife means that when it passes over the already sheared surface, it only combs the wool, which means that the material does not meet the conditions for pinching. The rotational movement of the knife eliminates the repeated cutting of the wool (formation of chips) and reduces the energy intensity of the process by 20%.

We have developed a test bench that can determine the force of resistance to the movement of the shearing machine in the wool layer and the power consumption of the machine movement, which is consumed during shearing, by changing the speed of the shearing machine.

Comparing the MSU-200 and the rotary shearing machine, it can be noted that the power consumption of the developed machine, compared to the basic one, decreased by 2.2-2.3 times. The force of resistance to movement decreased by 1.2-1.4 times, and the amount of shearing decreased by 3.2-3.5 times.

Published: March 2023

The article analyzes the maintenance of existing agricultural machines in a working condition, which should be followed by the development of a maintenance system taking into account the conditions of agricultural sector reform. Operational, technological, and functional indicators were determined for direct combining of wheat. Under these operating conditions, the productivity for 1 hour of the main time was 17.6 tons, which is slightly less than the technical conditions - at least 18 tons. This is due to the low yield of the harvested crop. The self-propelled combine harvester KZS-9M steadily performed the technological process, as evidenced by the value of this coefficient equal to 1, which also corresponds to the value according to the technical specifications - not less than 0.98. All indicators of the quality of the technological process: grain losses behind the combine thresher and behind the reaper, the quality of grain from the combine hopper (crushing and the content of trash impurities) are within the permissible values according to the technical specifications. For example: grain losses behind the combine thresher were 1.06% (according to the technical specifications, no more than 1.5%) and behind the reaper 0.24% (according to the technical specifications, no more than 0.5%). During the observation period, five failures were detected on these combines, all of which were of the second complexity group. The average number of failures of complexity group II was 1.7. The operating time between failures of complexity group II was 307.6 hours (5006.7 tons), which is higher than the value required by the technical specifications of at least 100 hours. For the four seasons of observation of the combines, the average operating time was 1055 hours (11387 tons). At the same time, the time between failures of complexity group II was 105.5 hours over the four years of observation (according to the technical conditions, at least 100 hours). This indicates sufficient technical reliability of the combines. No parts (assemblies) that have reached the limit of wear (resource) over the four years of observations of the KZS-9M self-propelled combine harvesters were found.
Analytical Provisions for Estimating the Readiness Coefficient of Self-Propelled Sprayers under Technical Control Modes
Authors: Любченко І.
Published: March 2023

The main indicator used to study reliability is the availability factor, which means the probability that a self-propelled sprayer will be in working order at any time, except for the planned periods during which the self-propelled sprayer is not expected to be used for its intended purpose. Deriving an analytical expression for the availability factor is a rather laborious operation. The labor intensity increases with the complexity of the graph, i.e., when trying to take into account more technical conditions, factors that affect the process of technical control of self-propelled sprayers. In this regard, it is advisable to solve a problem of this kind using a simulation model. Using the Stateflow modeling tool of the Matlab software package, a model was developed that allows simulating discrete-event models. The Stateflow model of self-propelled sprayers for assessing the availability factor during technical control of programs. The results of the simulation modeling are the values of the availability factor for different maintenance programs - =0.88 and =0.90, which allows us to draw conclusions about the impact of the maintenance program for self-propelled sprayers on the value of the availability factor. The error probabilities ranged from 0 to 1 and were equal: and , which is quite reasonable in cases where technical control differs only in the place of measurement of the technical condition parameter, and the means of measurement are the same. The author found that the availability factor is sensitive to the second kind of error in this case. Ways for further research are found in the study of other programs of technical control of self-propelled sprayers, in which the availability factor is sensitive to the probability of first-order errors.

Published: March 2023

Fuel and economic performance is one of the most important operational indicators that determine the quality of modern motor vehicles and are included in the set of criteria for assessing the constructive improvement of vehicles. The rapid pace of development of the construction, agricultural and other industries ensures an increase in the percentage of use of modern specialized vehicles, which, in turn, ensures an increase in the use of fuel and energy resources, so it is of great practical importance for the efficient use of fuel to improve the fuel efficiency of vehicles during transportation. One of the most effective ways to reduce fuel consumption is to increase its fuel efficiency by optimizing the parameters of the engine's operating mode during transportation, taking into account the design parameters of the specialized vehicle and the transported cargo.

Dump trucks are designed to transport various (mostly bulk) cargoes and belong to the group of special road transport vehicles that are in great demand in Ukraine. The factors that influence the demand for this special equipment for cargo transportation are as follows: versatility and functionality, as the dump truck is equipped with the function of automatic unloading of cargo. The body is unloaded by tipping it mechanically. This method allows you to unload bulk materials, and not only bulk materials, to a clearly defined place and minimize losses for additional operations.

The scope of application of this type of transport is quite wide: in construction, in quarries during the development of mineral resources, in the agricultural sector and at manufacturing enterprises.

Today, the demand for dump trucks is growing in Ukraine. According to 2016 statistics, sales of new dump trucks accounted for 46%. At the beginning of 2017, statistics showed a 36% increase in this special equipment compared to 2016, and in 2018, sales of dump trucks in Ukraine amounted to 21.9%.

Financial, work-based contributions underly entitlement to pension benefits in Israel. This article examines the historical development of the pension system in Israel, including the pensions of long-term military veterans and Jewish immigrants, expanding the notion of ‘contribution’ beyond its initial meaning of work-based financial accumulation. Specifically, it shows that both before and after the erosion of the union-protected contributory rationale in the 1990s, an alternative path to pension entitlement has operated through non-financial, political-symbolic contributions. The analysis emphasizes the importance of sectoral organizations for the broader analysis of social policy, and for understanding the structure of “social citizenship” and its discriminatory implications in Israel.
Engagement, Psychological Fit, and Evolution in Movies on Our Minds
Authors: Turvey Malcolm
Published: March 2023

Cutting's quantitative approach to analyzing films enables him to discover many fascinating and important design features of mainstream movies as well as how they have changed over cinema's history. Cutting also proposes plausible psychological explanations for some of these features and changes. However, Cutting places his empirical findings and his psychological explanations of them within a broader account of what he calls the evolution of cinematic engagement. For Cutting, movies have “evolved” to better “fit” our psychological capacities and have therefore become more “absorbing.” While some aspects of this account are plausible, others are less so. In this article, I therefore focus critically on Cutting's use of the concepts of “evolution,” “psychological fit,” and “engagement.”

Probabilistic evaluation of the axis distance’s influence on the flexural strength deterioration of reinforced concrete beams under ISO 834 fire
Authors: Truong Thang Nguyen , Viet Hung Dang
Published: March 2023

The distance from the nearest concrete exposed surface to the centroidal axis of main longitudinal steel re-inforcing bars, so-called axis distance, plays a critical role in ensuring the safety of reinforced concrete (RC) structures under fire, as it helps the rebars not being directly exposed to heating in a fire incident. However, a large axis distance value could reduce the effective height as well as the beam’s flexural strength at ambient condition. In order to determine the appropriate values of axis distance, this article developes a data-driven method for predicting the flexural strength deterioration (FSD) of RC beams under ISO 834 standard fire based on the material and geometrical inputs. This method consists of two main stages: (i) Establishing a theoretical/experimental database by collecting experimental data from the literature; and (ii) Engineering a probabilis-tic model based on the Bayesian Neural Network. The results obtained show that the proposed approach is a practical tool that is capable of performing quick and reasonably accurate analysis such as degradation curves of FSD against exposure time. In addition, the uncertainty related to the prediction results is also evaluated, providing useful information for structural fire engineers to achieve conservative designs.
Compressibility characteristics of clays in the Red River Delta
Authors: Dung Nguyen Tien , Khin Phyu Sin
Published: March 2023

The Red River Delta (RRD) is the second largest delta in Vietnam and is a significant economic zone in the country, encompassing important cities and economic zones. Geologically, the delta consists of clay layers distributed all over its area, which strongly impact the foundation designs of the infrastructure system (e.g., highways, industrial parks, harbors). However, up to date, there were no comprehensive studies on the compressibility characteristics of the clays in the delta. This study presents a primary study on some compressibility characteristics of clays in the whole delta with an emphasis on the use of CPTu data in the interpretation. For this, high-quality field and laboratory test results obtained from four research test sites and eight project sites were analyzed to depict the characteristics. The results indicate that the clays in the delta are typically soft to medium stiff and normally consolidated to slightly overconsolidated, which represent typical characteristics of young Holocene deposits. The compression index (Cc) of the clays was found to have good correlations with natural water content (Wn) or in-situ void ratio (e0). The ratio of radial coefficient of consolidation from a consolidation test with a central drain (CD) to the vertical coefficient of consolidation from the standard consolidation test (i.e., cr,CD/cv) from the 4 research test sites is on average 2.76 (log t method) and 2.32 (root t method) and these average ratios are found typical for deltaic soil deposits. The correlations for the remolded samples indicate that the drainage type has a strong influence to the induced coefficients of homogeneously remolded soils. Results from this study help geotechnical engineers have a general view on the compressibility characteristics of the clays in the delta, which in turn helps secure optimal foundation design solutions.
Machine learning-based pedo transfer function for estimating the soil compression index
Authors: Linh Khanh Pham Nguyen , Bao Ngan Nguyen Huu
Published: March 2023

Soil compression index (Cc) plays a vital role in describing the settlement behaviors of geotechnical infrastructures. The conventional Oedometer test broadly used to determine Cc is time-consuming and expensive, which challenges incorporating the high spatial variability of Cc. Alternatively, this study utilized the pedo transfer function (PTF) concept to develop a predictive model on the extreme gradient boosting (XGB) framework for estimating Cc with high accuracy and low effort. The presented XGB-PTF implemented on the database is acquired from 40 boreholes in Ho Chi Minh city and its vicinity to learn and recognize the correlation patterns of Cc and the easily-obtainable soil parameters (i.e., grain size distribution, unit density, moisture content, Atterberg limits). Rigorous evaluation with standard regression metrics demonstrated the efficiency and excellent performance of the XGB-PTF (e.g., low root-mean-squared error of 0.089 and a high coefficient of determination of 0.903). Furthermore, the presented framework showed its superiority over the current empirical equations in estimating Cc by higher prediction accuracy and applicability to the broader range of soil types. Given efficiency, flexibility, and dynamics, the presented model is expected to be a versatile approach to quantizing and advancing the knowledge of soil characteristics over a regional area.

This study aims to explain the problems in government programs in the provision of social assistance to the poor which are not appropriate. Based on the direction of President Joko Widodo through Ratas on March 16, 2016 states that social assistance is provided on a non-cash basis, one of which is through the BPNT program based on Permensos No.11 2018 which is a transformation of the Rastra program which has problems in distribution. The BPNT program is expected to reduce the burden of spending in meeting the basic needs of poor families, as social protection and poverty reduction. Batu City is one of the areas chosen as a Pilot Project since the BPNT program was formed in 2017. The implementation of the BPNT program in each region is not the same. There are even KPM who do not know if they receive BPNT Social assistance. So to find out the implementation of the BPNT program in Batu, monitoring and evaluation is needed in its implementation. The method in this study uses descriptive qualitative approach, providing an overview of developments in the application of the BPNT program in poverty alleviation. Data collection techniques are done by observation, interview and documentation. The research theory of the BPNT Program uses Monitoring and Evaluation of policies according to William Dunn who argues that monitoring is an internal and ongoing activity, a source of information which will later be used as an evaluation material to find out whether a policy is successful or not. The results of this study indicate that the implementation of monitoring and evaluation of the BPNT Program in Batu has implemented the principles of monitoring and evaluation and has been running quite well by BSP facilitators and the BPNT program is considered to have been on target, so as to accelerate the implementation of poverty reduction. BPNT program has been given to KPM Kota Batu as many as 5,649 KPM in 2018 then decreased in 2019 which is as many as 3,992 KPM. The inhibiting factors in monitoring and evaluating the BPNT program are first the capacity of Human Resources (HR) second, namely time.

Novel blood typing method by discrimination of hemagglutination and rouleaux using an erythrocyte aggregometer
Authors: Higuchi Makoto , Sekiba Yasuhiro , Watanabe Nobuo
Published: March 2023

BACKGROUND: In pretransfusion blood typing, pretreatments such as centrifugation and suspension of red blood cells (RBCs) and mixing them with sufficient amounts of reagents are required, but these steps are time-consuming and costly. OBJECTIVE: Aiming to develop a new blood typing method that requires no dilution and only a small amount of reagent, we attempted to determine blood type using syllectometry, an easy-to-use and rapid optical method for measuring the RBC aggregation that occurs when blood flow is abruptly stopped in a flow channel. METHODS: Samples of whole blood from 20 healthy participants were mixed with antibody reagents for blood typing at mixing ratios of 2.5% to 10% and measured with a syllectometry device. RESULTS: Amplitude (AMP), one of the aggregation parameters, showed significant differences between agglutination and non-agglutination samples at mixing ratios from 2.5% to 10%. Although there were significant individual differences in aggregation parameters, calculation of AMP relative to that of blood before reagent mixing reduced the individual differences and enabled determination of blood type in all participants. CONCLUSIONS: This new method enables blood typing with a small amount of reagent, without the time-consuming and labor-intensive pretreatments such as centrifugation and suspension of RBCs.

Background: Due to clinicoradiological similarities, including amnestic cognitive impairment and limbic atrophy, differentiation of argyrophilic grain disease (AGD) from Alzheimer’s disease (AD) is often challenging. Minimally invasive biomarkers, especially magnetic resonance imaging (MRI), are valuable in routine clinical practice. Although it is necessary to explore radiological clues, morphometry analyses using new automated analytical methods, including whole-brain voxel-based morphometry (VBM) and surface-based morphometry (SBM), have not been sufficiently investigated in patients with pathologically confirmed AGD and AD. Objective: This study aimed to determine the volumetric differences in VBM and SBM analyses between patients with pathologically confirmed AGD and AD. Methods: Eight patients with pathologically confirmed AGD with a lower Braak neurofibrillary tangle stage (<III), 11 patients with pathologically confirmed AD without comorbid AGD, and 10 healthy controls (HC) were investigated. Gray matter volumetric changes in VBM and cortical thickness changes in SBM were compared between the two patient groups (i.e., AGD and AD) and the HC group. Results: In contrast to widespread gray matter volume or cortical thickness loss in the bilateral limbic, temporoparietal, and frontal lobes of the AD group, these were limited, especially in the limbic lobes, in the AGD group, compared with that of the HC group. Although bilateral posterior dominant gray matter volume loss was identified in the AD group compared with the AGD group on VBM, there was no significant cluster between these patient groups on SBM.

Published: March 2023

Forecasting is making predictions about what will happen or how things will change. This can help people avoid blindness and losses and play a significant role in their lives. In multi-attribute prediction problems, the correlation between attributes is often ignored, which affects prediction accuracy. Based on fuzzy rough sets and logistic regression, this paper proposes a new logistic regression method that fully considers attribute correlation, namely a twin logistic regression method based on attribute-oriented fuzzy rough sets. Firstly, attribute-oriented fuzzy rough sets are studied and analyzed. Then, the optimistic and pessimistic predictions are achieved by fuzzy rough sets and logistic regression, and the final result is obtained by fusing the optimistic and pessimistic predictions. Finally, the effectiveness of the twin logistic regression method is verified.

Published: March 2023

In this paper, the existence, uniqueness and global exponential stability of pseudo almost periodic solutions for a class of octonion-valued neutral type high-order Hopfield neural network models with D operator are established by using the Banach fixed point theorem and differential inequality techniques. Compared with most existing models, in this class of networks, all connection weights and activation functions are assumed to be octonion-valued functions except for time delays. And unlike most of the existing methods of studying octonion-valued neural networks, our method is a non-decomposition method, that is, the method of directly studying octonion-valued systems. The results and methods in this paper are new. In addition, an example and its numerical simulation are given to illustrate the feasibility of our results.
Research on variable weight CLIQUE clustering algorithm based on partial order set1
Authors: Cao Maojun , Hu Yingda , Yue Lizhu
Published: March 2023

The uncertainty of weight makes the weight density between samples not fixed. Aiming at the problem that the existing CLIQUE clustering algorithm does not consider the weight of object features, which leads to low accuracy, an improved weighted method combined with the thought of posets is proposed. In addition, this method does not need accurate weight assignment, only the weight order can run efficiently. First, the weight order of object features is obtained, and then the partial order weight is applied to the original data to obtain weighted data with weights. Then the traditional CLIQUE algorithm is used to cluster according to weighted data, and finally the partial order weighted CLIQUE model is obtained. Through the experiment of six groups of data, the results show that: under the given weight sequence constraints, the clustering quality of the weighted CLIQUE model is significantly higher than that of the unweighted model, and the clustering accuracy and other aspects are significantly improved. In this method model, weight information is effectively integrated into the algorithm when only the feature weight order is obtained, and the function of feature weight is fully played to enhance the robustness of clustering results. At the same time, the idea of poset can effectively integrate expert information, and the representation of the nearest neighbor elements in Hasse graph can show the effect intuitively. It is an effective improvement method of CLIQUE clustering algorithm.
Gender, faith, education, and family background in the United Arab Emirates: A case study of women professionals
Authors: Kawanzaruwa Gallie , Mufuka Kenneth. N.
Published: March 2023

This paper explores some of the reasons behind the remarkable accomplishments of five women managers in higher education settings in the United Arab Emirates: despite four of them being brought up in extremely humble, poor, albeit nurturing environments. It adopts a critical feminist approach via narrative analysis of interviews with the five women, drawing out key themes around their family backgrounds, education, and Islamic faith, juxtaposing these against the literature. It finds that in all the five women, their backgrounds instilled a remarkable tenacity, resilience, and drive to succeed against the odds; but that they remain major exceptions in Emirati society, despite the government's work over recent decades to provide greater leadership opportunities for women in the workplace. The women encountered a host of cultural obstacles on their way up, from both their families and later, in their professional lives. This study observes that, while their stories are inspirational for all women and girls, especially those living in the Gulf region, there is clearly still a huge amount of work to be done by policymakers. The paper makes recommendations in such regard, highlighting the pressing need for the private sector to follow in the government's footsteps and provide more opportunities for women at executive levels in leadership and management.
The Impact of Financial Inclusion on Economic Development
Authors: Mostafa Seifelyazal , Ashraf Salah Eldin , Marwa ElSherif
Published: March 2023

The importance of an inclusive financial system is considered a priority all over the world. The importance of financial inclusion raised from the problem of financial exclusion were most of the Middle east and North Africa (MENA) region countries didn’t have enough formal financial services and most of the population didn’t have access to formal bank accounts. Financial inclusion not only helps individuals and families, but collectively it develops entire communities and can help drive economic development. The purpose of this study is to assess the effects of financial inclusion on economic development in the MENA region. The aim of this study is to investigate the impact of financial inclusion on the economic development of MENA region countries. To achieve this aim, a three-dimension Financial Inclusion Index (FII) was created using Principal Component Analysis (PCA) to measure each country’s level of financial inclusion. These dimensions are access, usage, and quality of financial services. Data was collected from 18 MENA region countries using a sample period from 2004-2019. Based on a 2-step Generalized Method of Moments (GMM) system, the results showed that an increase in the level of financial inclusion leads to the increase of MENA region countries’ economic development.
Introducing the Special Issue on Corporate Law and Climate Change – (How) Can Corporate Law Steer Companies Towards Meeting the Paris Climate Goals?
Authors: Hösli Andreas , Monti Alessandro
Published: March 2023

Corporate law and climate change have long been viewed as two entirely separate topics.1 In recent years, scholarly attention to the intersections between the two areas has certainly grown.2 Regulators and supervisory authorities, too, are increasingly turning their minds to how corporate law can be used (better) to strengthen corporations’ actions towards achieving international, supranational and national climate targets.
Brazilian Corporate Sustainability Regulation in the Green Transition: Missing the Forest for the Trees
Authors: Neder Cerezetti Sheila C. , de Oliveira Junqueira Gabriela
Published: March 2023

The article describes and analyses new regulatory and governance rules regarding corporate sustainability regulation in Brazil, including the new provisions by the capital markets, the financial authorities, and private frameworks. This is done through the theoretical lens of a critical approach to socio-ecological transformation, shedding light on the broader context in which the institutional innovations take place: the political project of relying on finance to guide the transformation and the current transformations (i.e., the dismantling) of the traditional apparatus for environmental protection. In so doing, the contributions are twofold: on an empirical level, the article presents an overview of new rules regarding corporate governance and climate change in Brazil, serving as a useful source for comparison with other jurisdictions and a critical analysis of trends and differences in Northern and Southern Countries. On the theoretical level, we argue in favour of the need for a holistic approach that considers the broader regulatory context including the political agenda boosting the reforms in internal corporate governance and the circumstances of external environmental regulation. As such, we stress the interplay between extra-corporate and intra corporate governance tools in fostering corporate sustainability.

Published: March 2023

This document presents the requirements met for the design, construction and first validation of a mechanical ventilation system to be used in patients with respiratory failure, which in the initial context was due to the COVID-19 pandemic. The design required the use of computer aided drawing software (Computer Aided Design) CAD and the construction required the use of installed capabilities in mechanical, electropneumatic, electronic, biomedical and automation manufacturing of Don Bosco University (El Salvador) institutes and centers. The adjustment, configuration and programming works were in charge of research professors specialized in these disciplines. The elements used for its construction were available in the Salvadoran market, considering the closure of the borders as a government measure in face of the expansion of the pandemic. After the design, manufacture and commissioning stage, measurements of the conditions of the supplied air were made with the help of professionals dedicated to the maintenance of medical equipment and with the approval of internist doctors. The results achieved are those obtained with paramedical equipment and with first aid equipment, for which it has been foreseen that the equipment can be tested in a subsequent instance with the certified medical union.
