Why Datastream Permutations Need Diagnostics
Authors: Hart Jordan D. A. , Franks Daniel Wayne , Brent Lauren , Weiss Michael N.
Published: July 2022

Datastream permutations are commonly used to test null hypotheses in animal social network analysis. Permutation methods are inherently stochastic and, like all stochastic processes, can be unreliable if appropriate diagnostic procedures aren't employed. Though datastream permutations are widely used in behavioural ecology, sufficient diagnostic checks have not yet been adopted to guarantee their reliability. In this paper we highlight that without proper checks, datastream permutations can be severely unreliable, but that using diagnostic tools developed for Markov chain Monte Carlo methods can improve the reliability of inferences.
Count regression models for keyness analysis
Authors: Sönning Lukas
Published: July 2022

A wide variety of measures have been used in previous work to assess the keyness of items in a particular domain of language use. The present paper explores an approach to keyword analysis based on regression modeling. Specifically, we use a form of negative binomial regression, which offers a number of advantages compared to existing techniques for identifying typical items in a target corpus. Thus, it is responsive to the multidimensional nature of keyness and can address multiple aspects of typicalness simultaneously, using a single statistical model. Further, metrics of interest can be enriched with confidence intervals, which allows us to isolate descriptive and inferential indicators of keyness. Finally, all quantities are based on a text-level analysis, which accounts for the fact that the target and reference corpus consist of text files and adjusts uncertainty estimates accordingly. As an illustrative case study, we rely on COCA to identify key verbs in academic writing and demonstrate how negative binomial regression may be used to this end. Our checks on the coverage rate of the 95% confidence intervals indicate that this model seems to be adequate for purposes of statistical inference. Due consideration will also be given to the limitations of this procedure, and we conclude by outlining the kinds of keyness analyses for which count regression models may be a worthwhile approach. The online supplementary material for this paper provides data and R code for the implementation of keyness regression.
The Impact of Bilateral Anodal tDCS over Left and Right DLPFC on Executive Functions in Children with ADHD
Authors: Salehinejad Mohammad Ali , Vosough Younes , Nejati Vahid
Published: July 2022

Transcranial direct current stimulation (tDCS) is increasingly used for therapeutic purposes in attention-deficit hyperactivity disorder (ADHD). The dorsolateral prefrontal cortex (DLPFC) is the most targeted region of tDCS studies in ADHD. There is limited knowledge and mixed results about the relevance of left or right DLPFCs in ADHD’s cognitive deficits. No study so far has investigated the impact of the increased excitability of both left and right DLPFC with anodal tDCS on cognitive deficits in ADHD. Here, we explored the impact of online bilateral anodal left and right DLPFC tDCS on executive dysfunction in children with ADHD. Twenty-two children with ADHD (mean age ± SD =8.86 ± 1.80) received bilateral anodal online tDCS over the left and right DLPFC (1.5 mA, 15 min) in two separate sessions in active and sham states. They underwent a battery of four neuropsychological tasks of executive functions during stimulation that measured working memory, cognitive flexibility, response inhibition, and executive control. Bilateral anodal left and right DLPFC tDCS did not improve performance on working memory, cognitive flexibility, and response inhibition. Executive control was, however, partially improved for those who received active tDCS first. The upregulation of bilateral DLPFC tDCS with anodal polarity does not improve executive dysfunction in children with ADHD. The unilateral modulation of DLPFC with anodal tDCS may be more beneficial to cognitive deficits in ADHD in light of previous works targeting only left and/or right DLPFC.
Melanie as a Subaltern Woman: An Analysis of JM Coetzee's Disgrace
Authors: Ghimire Surendra Prasad
Published: July 2022

This article reports how Melanie was subaltern character in the novel Disgrace written by J M Coetzee. As a literary qualitative research, this paper utilized subaltern theory developed by Ranajit Guha and Gayatri Chakravorty Spivak to analyze lived experiences of injustices and exploitation over her. The findings of this study revealed that Melanie as a subaltern woman; victimized and suppressed from racial, gender and other various layers of injustices. Likewise, she belonged to minority Muslim community and, due to which she had to face tremendous injustices. Although she was an educated university student, was many times raped by her own professor; consequently, she was tortured with psychological pain and very often faced family conflicts indeed. As a result of patriarchal ideology, she remained silence and further became submissive and docile character. However, the findings further exhibited that after being exploited for long; she developed consciousness about the injustices over her; thereby, she rejected such injustices by forwarding the case against her own professor to the university. The findings have overarching consequences which will contribute to explore further issues of subaltern in the novel.

Do MSMEs Create Employment? Attestation from India
Authors: Rekha  , Jain Akansha
Published: July 2022

The Micro, Small, and Medium Enterprise (MSME) sector has developed as a vibrant sector of the Indian economy and is an essential engine of the economy. It contributes significantly to the growth of entrepreneurship and creates the second-largest number of job opportunities. In 2019-2020, the MSME sector will contribute considerably to the development of the Indian economy, accounting for 95 percent of industrial units with an extensive network of 63 million firms, 29 percent of GDP, and nearly 49.8% of exports employing roughly 111 million people. Because the global economy is slowing, it should emphasize growing the MSME sector to improve job opportunities, particularly for young people. These MSMEs create employment possibilities and aid in industrialization in rural areas, reducing income inequality among inhabitants. MSMEs contribute considerably to the development of the Indian economy through exports, domestic production, minimal investment requirements, operational flexibility, and technology-oriented firms, among other things. So, this paper has attempted to understand the role of MSMEs in providing employment opportunities and pushing toward the country's inclusive development. The data for the study has been collected from various secondary sources such as government websites, magazines, multiple reports, and newspapers. Descriptive statistics, correlation, and co-integration analysis were used in the study. The result shows, Have MSMEs created job opportunities in the economy? We used time-series data to analyze the long-term relationship and trend between the variables.
Sexual consent attitudes and behaviour: Associations with sexual health education, sexual consent education, and sexual attitudes
Authors: MacDougall Airica , Craig Sarah , Goldsmith Kaitlyn , Byers E. Sandra
Published: July 2022

Because many young adults do not consistently give and receive explicit consent in their sexual relationships, it is important to identify factors associated with sexual consent attitudes and behaviour. In this study, we assessed the extent to which sexual health education, sexual consent education, sexual attitudes, and perceptions of social norms were associated with sexual consent attitudes and behaviour. Participants were 196 undergraduate students between the ages of 18 and 25 enrolled at an eastern Canadian university. At the bivariate level, we found evidence for the importance of sexual consent education by parents, sexual attitudes, and perceptions of social norms with respect to sexual consent attitudes and behaviour. Multiple regression analyses showed that more positive perceptions of social norms, more liberal sexual attitudes, and more sexual consent education from parents were uniquely associated with lower negative attitudes towards sexual consent and more consistent use of explicit sexual consent. More positive perceptions of social norms and less sexual experience were uniquely associated with more positive sexual consent attitudes. Only perception of social norms was uniquely associated with less use of an indirect behavioural approach to establishing consent. The results are interpreted in terms of their implications for enhancing sexual consent attitudes and behaviour among young people.
Extraterritorial sanctions as a challenge in the US-EU relations
Authors: Agarval D.
Published: July 2022

The United States of America is a subject of international relations which took the leading position in application of unilateral sanctions, especially extraterritorial restrictive measures. The main target of the US extraterritorial sanctions are legal entities and individuals which are in the jurisdiction of third countries, namely member states of the European Union. The increasing sanction pressure against Iran in the 2nd half of 2010s has brought the problem of American extraterritorial measures in the US-EU relations to the fore. Consequently, the aim of this research is to reveal the contradictions between the USA and the EU due to the strong influence of secondary sanction on the European business and examine the main countermeasures taken by the EU authorities in this regard.

Results and prospects of geological mapping of the Arctic shelf of Russia
Authors: Gusev Evgeny
Published: July 2022

The results of compiling the sets of the State Geological Map at a scale of 1:1,000,000 for the Arctic continental shelf of Russia are analyzed. Results are summed up, and the main problems of geological mapping are outlined. The results of geological and geophysical studies of the Arctic Ocean are of great importance for deciphering the geological evolution. The Arctic shelf is the widest shelf in the world, while the spreading ocean basin is one of the narrowest and is characterized by anomalous structural features. The main problems of geological mapping include identification the sedimentary cover/folded basement boundary, interpretation the geodynamic evolution of the shelf and adjacent ocean, determining the rates of sedimentation and stratigraphic subdivision of the sedimentary cover due to a small number of key boreholes. It is promising to further study problem areas with unclear features of geological structure as well as small-scale mapping in areas of industrial development on the Arctic continental shelf.

Authors: Fallah Nasser , Kiany Gholam Reza , Tajeddin Zia
Published: July 2022

This experimental study aimed to explore the effect of entrepreneurship education among English language teaching (ELT) learners in Iran. To this end, an entrepreneurship awareness-raising intervention was designed and evaluated through a mixed-method explanatory sequential design with hypotheses rooted in social cognitive career theory. The effectiveness of the intervention was first investigated quantitatively through pre-test and post-test among 41 ELT learners. Then, semi-structured interviews were conducted among 15 participants to triangulate and further explain the quantitative findings. The results of repeated measures of MANOVA revealed that ELT learners’ entrepreneurial intention, entrepreneurial self-efficacy, entrepreneurial mindset, and entrepreneurial outcome expectations improved significantly from pre-test to post-test under the effect of the intervention. Further, the findings of qualitative data analysis confirmed the quantitative results and revealed that all of the participants took great satisfaction in the course, and they believed that the effectiveness of the course was even beyond their expectations. Implications are discussed.

Published: July 2022

Aim: to assess the rate and pattern of the clinical course of small intestinal bacterial overgrowth (SIBO) in irritable bowel syndrome (IBS). Patients and Methods: this study enrolled 100 patients aged 18–68 (mean age 33.5 [26; 46.25] years) with established IBS. The patients were divided into two groups. The IBS with diarrhea (IBS+D) group included 54 patients (mean age 36 [23.0; 49.5] years). The IBS without diarrhea (IBS–D) group included 46 patients (mean 37 [24.5; 49.5] years). All patients underwent lactulose hydrogen breath test using Gastroplus+ monitor to establish SIBO. A positive lactulose hydrogen breath test (a rise of ≥ 20 ppm by 90 min with dual-peak profile or a steady growth of ≥ 12 ppm from baseline in hydrogen) suggested SIBO. Medical history, clinical and lab tests, and the parameters of the quality of life (QoL) using SF-36 and QOL questionnaires were evaluated. Results: the occurrence of SIBO in patients with IBS was 32%, i.e., 37% in the IBS+D group and 28% in the IBS–D group. Multivariate analysis has demonstrated that flatulence in IBS increases the chances of having SIBO by 110.9 times. Univariate analysis revealed universal clinical associations of SIBO with bloating, flatulence, nausea, weakness, tearfulness, and irritability in IBS. Hepatic steatosis is typical for IBS with SIBO (OR=1.75, 95% CI 1.01–3.99, p=0.037). The use of loperamide in IBS+D is associated with a 2.2-fold increase in SIBO risk. SIBO in IBS is associated with a reduction in QoL, as demonstrated by most SF-36 scales (physical and emotional health) and QOL. Conclusions: SIMO in IBS mimics exacerbation, thereby resulting in the prescription of inadequate treatment.

Hepatic encephalopathy (HE) is one of the most common and dangerous complications of cirrhosis. HE is considered a predictor of death within the first year after onset in more than 60% of patients. Recently, studies have focused on minimal HE (MHE) which is characterized by medical, social, and clinical relevance. MHE patients are a risk group for cirrhosis complications and hospital admission. This demonstrates the need for early therapeutic and preventive measures for MHE. This paper provides information on current diagnostic and treatment tools for MHE in cirrhosis and illustrates the efficacy of various therapies on the outcomes and quality of life in these patients. The authors conclude that one should rely on studies establishing the efficacy of rifaximin-α to regress MHE, improve the quality of life and reduce the risks of complications and decompensation in cirrhosis compared to other medications. Meanwhile, further studies are needed to reveal favorable and unfavorable predictors of disease course and to optimize therapeutic and preventive measures in these patients.

This paper reviews the pathogenic mechanisms of the development and progression of comorbid cholelithiasis (CL) and non-alcoholic fatty liver disease (NAFLD). The authors discuss gender and anatomic physiological patterns, and the effects of insulin resistance, obesity, adipose tissue hormones, and cholecystectomy on clinical morphological abnormalities in coexisting CL and NAFLD. In addition to lipid metabolism abnormalities, comorbid CL and NAFLD are characterized by deviations in the amount and proportions of fatty acids and hormonal imbalance (i.e., hyperleptinemia, leptin resistance, and insulin resistance). Cholecystectomy is an unfavorable factor for the progressive course of NAFLD and development of liver fibrosis. As a result, individualized management strategies are required in these cases. The authors present their own study that enrolled 183 patients with NAFLD. Their data demonstrate that coexisting NAFLD and CL have certain clinical laboratory signatures, while the postoperative period after cholecystectomy in patients with NAFLD is characterized by greater cardiovascular risk and liver fibrosis progression. The authors discuss the use of a combined preparation of ursodeoxycholic acid and sodium glycyrrhizinate in these patients. Two-component hepatoprotective treatment with this agent has pathogenically-target effect in comorbid NAFLD and CL.

Patients with liver diseases have a higher risk of hemostatic disorders. Meanwhile, despite a well-established opinion on a low risk of thromboses in cirrhosis, thromboembolic events cannot be totally ruled out in these patients. Increased risks of thrombotic events and venous thromboembolism in cirrhosis are accounted for by external (immobilization, surgeries, infections, comorbidities) and internal factors (reduced synthesis of anticoagulants, increased levels of estrogens). Practically, the selection of anticoagulant therapy in cirrhosis is difficult because of divergent hemostatic disorders and requires continuous and careful monitoring of hemostasis. In 2019, the American Gastroenterological Association (AGA) released guidelines on anticoagulant therapy in patients with cirrhosis and pulmonary embolism. We describe a patient with cirrhosis and pulmonary embolism. A management strategy was tailored to the AGA guidelines, the Russian Society on Liver Research guidelines, and the Russian Gastroenterological Association on Fibrosis and Cirrhosis and Complication Diagnosis and Treatment guidelines. This example of successful selection of anticoagulant therapy, multidisciplinary approach, and dynamic evaluation of all available methods of hemostasis control will be useful for practitioners.

Extensive use of solar panels for providing low-rise buildings with electricity has led to the development of methods for assessing the load-bearing capacity of solar panels, taking into account the size of the panel, the angle of inclination to the horizon and climatic loads in a given geographical area. The solar panels are calculated as plates hinged along the contour. Self-weight loads of the panel, snow, wind and ice loads are determined according to DBN B.1.2-2: 2006 "Loads and impacts" and are reduced to a component that is normal to the plane of the panel. Working formulas were obtained for determining the extreme and operational design values of loads, checking the strength and deflection of panels, as well as the maximum allowable spans according to the criteria of strength and structural rigidity. An example of calculation of solar panels placed at angles of inclination to the horizon from 15° to 75° on the roof of a building in Kropyvnytskyi were performed. Strength checks should be performed on combinations of panel self-weight, snow and maximum wind pressure. Deflection check at small angles of panels inclination is carried out taking into account the same combination of loads, and at big angles of inclination - taking into account only ice load. In all cases, the condition of rigidity is decisive. Permissible span L (smaller size) of a solar panel with 3 mm tempered glass sheathing in the conditions of Kropyvnytskyi varies from 0.68 m to 1.36 m. It increases as the angle of inclination increases and as the B/L ratio approaches to 1. The allowable span varies by 13…16% with length ratio of the larger side of solar panel to the smaller one in the range from 1.4 to 2.0. This allows to take the values of the allowable span, corresponding to the ratio of the parties B/L=2.0 in order to simplify the safety margin. The obtained working formulas and their implementation in the form of a calculation sheet in Microsoft Excel allows to perform similar calculations for other source data. Further research focuses on the establishment of allowable spans of solar panels of typical design in the conditions of each of the regions of Ukraine.

The purpose of the article was to substantiate the trend of changing the basic mass and dimensional parameters of body machines for the application of solid organic fertilizers depending on their capacity. The analysis of constructions of machines of production by the enterprises in the territory of the former Soviet Union and modern Ukraine is carried out. The research methods were based on the study of the main consumer parameters of machines using the information provided in the Catalogs of agricultural machinery and advertising information of enterprises-manufacturers of body machines. Processing and generalization of the collected data is carried out on the basis of correlation-regression analysis and using standard computer programs. The load-bearing capacity of the machines was taken as a factorial feature in the study, and their weight and overall length, width and height were taken as effective. The range of variation, arithmetic mean, standard deviation and coefficient of variation of factorial and performance characteristics are determined. There is a positive correlation between the mass of body machines, their overall length, width and height and load capacity of the machines with correlation coefficients of 0.959, respectively; 0.9000; 0.721 and 0.864 for correlation ratios of performance traits to factorial in the same sequence 0.960; 0.862; 0.859 and 0.840. According to certain correlation indicators, depending on the load capacity of the machines, the effective characteristics should increase. To finally clarify the nature and form of communication, the experimental values of the performance characteristics were aligned depending on the load capacity of the machines by the equations of direct power and logarithmic functions and exponents and hyperbolas. According to the calculated R2-coefficients, the best approximation to the experimental values of machine mass and overall length and height was provided by approximation of their change depending on load capacity by equations of lines with positive angular coefficients, and to experimental values of dimensional width by approximation of. It was found that depending on the load capacity of machines, their overall lengths and heights increase in a straight line with certain angular coefficients. The change in the overall width of the body machines for the application of solid organic fertilizers depending on the load capacity of the machines is described by the equation of increasing hyperbola.

The paper proposes that the element-modular method of the system of technical service of transport machines is based on the characteristic intervals of change of diagnostic parameters that determine the technical condition of their components, systems and units as elements. Theoretically substantiated changes in diagnostic parameters taking into account the degree of restoration of the technical condition of systems and units for technical service operations. The maximum resource of elements of the transport machine and the law of distribution of this indicator are considered. From the economic point of view the expediency of restoration of a technical condition of elements of transport cars by the offered system of technical service is proved. The criterion of economic expediency of application of technical actions on restoration of a technical condition of transport cars is offered. It is shown that according to this criterion it is possible to estimate the cost of technical actions to improve the technical condition of the transport vehicle and the fleet as a whole. The criterion of efficiency of technical action on improvement of a technical condition of an element of transport cars and a factor of rational use of a resource with possible situations is offered also. An algorithm for controlling the system of technical service of transport machines by the element-modular method has been developed. The results of forecasting technical control and regulation of the studied elements of transport vehicles: engine and transmission are considered. It is shown that the proposed element-modular method of technical service makes it possible to adjust certain technical operations to ensure and restore the appropriate level of operational reliability of transport vehicles.

Published: July 2022

The paper, based on a system-oriented approach, identifies how to increase the level of their operational reliability at the stages of the life cycle of transport machines operating in open pits and in the conditions of agro-industrial production. At the start-up stage of power units, a method of reducing the wear of parts is proposed. The scheme of realization of a way is developed. It is determined that it is effective to use this method when operating vehicles in harsh non-stationary conditions and "start-stop" modes. It is experimentally proven that the proposed method allows to save up to 15% of consumables and increase the life of the engine oil. The study of the effectiveness of the use of additives NIOD-5, RoilGold and the proposed additive KGMT-1 to motor oil was carried out at the stage of bench tests of power units of transport vehicles. It has been determined that the addition of a composite additive to the engine oil provides a steady increase in power, torque and reduction of specific fuel consumption. RoilGold and KGMT-1 additives work especially effectively. At the stage of operation of transport vehicles in open quarries and conditions of agro-industrial production, research proved the extension of the use of motor and transmission oil by 25 ... 40%, revealed a decrease in maintenance and the need to adjust the maintenance of vehicles. Based on the results of operational studies, a corrective table of terms of replacement of motor oil of transport vehicles operating in harsh non-stationary conditions is constructed. It is found out how to ensure the proper level of operational reliability of transport vehicles.

The criterion of its relative sensitivity (sensitivity) is constructed on the example of the function of technical condition of systems and units of machines as a function of diagnostic parameters. The relative criterion of sensitivity (sensitivity) for each diagnostic parameter and function of the state of weighting factors and operating time is considered. Using the properties of sensitivities and the method of realization of the theory of sensitivity of functions, partial criteria of relative sensitivity are obtained. Considering the set of functions of diagnostic parameters and reliability functions as functions of probability of trouble-free operation, it is shown that they are parametrically set. The connection of sensitivities of diagnostic parameters with the level of reliability of systems, units and machines in general is established. The block diagram of a method of definition of character of dynamic development of diagnostic parameters and indicators of reliability of a technical condition of systems and units of cars is developed. Mathematical models of relative sensitivity (sensitivity) for the most informatively significant diagnostic parameters of power units and transmissions are built on the basis of experimental research data. It is shown that mathematical models of sensitivity of diagnostic parameters allow to determine local values of sensitivity on operating ranges and are an effective tool for selection of operating ranges on which certain diagnostic parameters should be controlled to ensure proper reliability of systems, units and machines as a whole.

The indicators of road safety on the roads of Ukraine, on the example of Ternopil region are analyzed. It is established that currently in the world road accidents are one of the main causes of death and disability, and create annual GDP losses of 1 to 3%. It is investigated that for January - July 2021 on the street and road network of Ternopil region 1509 road accidents were registered, which is 19% more than for the same period last year (2020 - 1271 accidents). Organizational measures to improve traffic safety on the road network are proposed. Measures to improve traffic safety on the city's road network are divided into three main areas. The first direction was to organize traffic directly on the road network, the second - in the development of public transport and giving priority to travel. From the point of view of traffic safety, the construction of plans for coordination of traffic light facilities taking into account the movement of public transport can be an acceptable method. The third direction is the direct informational impact on drivers of vehicles.

Methods and approaches to modeling the goals of operations in transport systems are given, which allows to obtain not only purposeful, but also flexibly oriented solutions when choosing a strategy for forecasting their work. Partial decision-making tasks for structuring the initial information using the mapping method are defined. The classification of factors by the nature of uncertainty is given, which is one of the results of solving the problem of uncertainty analysis. Tasks are formulated that allow to quickly receive, analyze and process information. A formalized formulation of the problem of forming the initial set of strategies for modeling the problem situation in the transport system is presented. It was found that on the one hand, the set of alternatives between the desired result and the conditions of its implementation should be as wide as possible, which will ensure freedom of choice of the decision-maker and minimize the possibility of missing the optimal decision. It is determined that the initial set of strategies should be comprehensive and, therefore, quite narrow, which will allow the decision-maker to verify the alternatives on the available models with resource constraints. It was found that many components of the task of forming the initial set of strategies are clearly not set and are heuristically formed by the decision maker. Taking into account the indicator of reliability of transport systems, the main directions of solving the problem of satisfying conflicting requirements for many initial strategies are identified. It is found that the need, in the general case, to consider not one model, but their multilevel hierarchy is determined by the peculiarity of the efficiency study scheme, in which the description of the higher level depends on generalized and factorized lower level variables. The mathematical formula of the criterion of adaptability in the choice of solutions is given. The set of features that can be used as a basis for the classification of decision-making tasks in the transport system on the basis of the degree of certainty of information about the problem situation is generalized.
