Plyometric training is extensively used by coaches to enhance neuromuscular performance in a wide variety of sports. Due to the high demands of sprint speed and power output in elite sprinters and jumpers, sprint and jump coaches are likely to have great knowledge on this topic. Undoubtedly, this expertise is even more pronounced for Olympic coaches, who work with some of the fastest and most powerful athletes in the world, and who are required to continually maintain these athletes at optimal performance levels. Describing and discussing the practices commonly adopted by these coaches in detail and extrapolating this experience to other sport coaching contexts and disciplines may be extremely relevant. The current article presents, explores, and illustrates the plyometric training practices of Brazilian Olympic sprint and jump coaches, with a special focus on training programming and exercise selection.

Published: July 2023

The method for analyzing phase portraits of bifurcation diagrams of enterprise life cycle scenario models using IT pattern recognition has been proposed, which allowed to numerically determine the geometric parameters of the spatial forms that form the surfaces of phase portraits, and their size, corresponding to the loci of stability and interaction of four
populations in a network of trophic relations. To analyze the results of the recognition of phase portraits of ELC bifurcation diagrams, singular points of perturbation, attenuation, cycles, equilibrium, their stability, the input examples of the state of bifurcation have been classified into five separate clusters in accordance with the ELC development scenarios. An IT support algorithm for the corporate strategy for managing the evolutionary processes of enterprise development has been developed. It covers the following stages: analysis and evaluation of the internal and external environment of the enterprise population and trophic relations; identification of possible motives for changing trophic relations and causes of synergy; studies of the nonlinear dynamics of ELC model scenarios; analysis of many strategic alternatives; selection of a strategy and preparation of a strategic plan; monitoring the results of achieving a synergistic effect, which will allow choosing strategies depending on the ELC stages and ensuring the competitiveness of the enterprise.
PARETO OPTIMALITY: IS IT VALID AS A CRITERION FOR JUDGING SOCIAL EFFICIENCY IN AN ISLAMIC ECONOMY
Authors: Fotouh Nagah Abdul Alim Abdul Wahab Abul
Published: July 2023

Optimization aims to reach the best, and in order for optimization to have
meaning, there must be a function of goals that are maximized, and there should be more than one solution available to choose the best among them. The most efficient situation according to Pareto optimization is the situation in which we cannot make a member of society better off without making a member or other members worse off in the country under consideration. The maxima we arrive at is just one of an infinite number of Pareto optimizations from which we cannot choose without assuming a scale of values to evaluate individual utilities because there is always a system for weighing these utilities that makes any point optimal. Thus Pareto optimization is a criterion that requires the existence of a function of value goals that is different in the Islamic economy from that
in the capitalist economy.
Justice in the Islamic economy has a concept based on rights regulated by Islamic Sharia, and this makes difference in the content and scope of the optimization process, which makes justice an organic component of the concept of efficiency in the Islamic economy, and the criterion of
Pareto optimization is a criterion that does not achieve justice by itself.
Pareto optimization is a quantitative criterion that depends in its judgment on efficiency on the overall quantitative result and does not take into account qualitative aspects of great importance in relation to the concept of efficiency and its judgment in the Islamic economy.
Reaching a situation in which it is not possible to improve the situation of some people without making others in a worse situation, which is what is known as Pareto optimization can serve as a criterion for judging efficiency in the Islamic economy if the rulings of the Sharia in the
acquisition, use, and spending of funds are applied in the economy under consideration, taking into consideration there is a difference in the content and scope of the maximization process, which makes justice an organic component of the concept of efficiency in the Islamic economy, and the difference in the concept of justice itself, and if the concept of “improving the status of some” is determined within the framework of achieving sufficiency, and the concept of “worse situation” is
determined by violating sufficiency. Based on the foregoing, we suggest that the Pareto criterion, by itself, is not sufficient to judge efficiency in the Islamic economy.

Authors: Khangura Sara D. , Bailey Sharon
Published: July 2023

Findings from evidence syntheses describing the comparative clinical effectiveness of platelet-rich plasma injection (PRPi) in the treatment of chronic tendinopathies of the upper extremities were variable.

Whereas findings describing function showed no clear demonstration of effect, some findings describing pain suggested there may be potential for a benefit of PRPi with higher concentrations of leukocytes or longer durations of follow-up.

Lack of a clear demonstration of the comparative clinical effectiveness of PRPi in chronic tendinopathies of the upper extremities does not currently support decision-making in favour of its use.

Published: July 2023

The Covid-19 pandemic brought about a lot of interference in learning institutions. Universities were not spared by this pandemic, and this brought about a need to reconsider modes of learning which had all along been face-to-face.  Online learning has proved itself as a promising instructional medium as well as a prime area for researchers to investigate its effectiveness on learning and pedagogy. Covid-19 provided an avenue to explore the use of technology in learning given that learning institutions were closed indefinitely. Online infrastructure refers to the hardware, software and internet availability in learning institutions that promote distance education or e-learning. This study sought to establish the status of online pedagogical infrastructure in public universities with a focus on Masinde Muliro University of Science and Technology (MMUST). The study adopted a descriptive survey design. The study population comprised of staff and students of MMUST. Stratified sampling was used to get a sample size of 682 respondents. Data was collected using questionnaires, interviews, Learning Management System content analysis, and observations. The study found that the available online pedagogical infrastructure in MMUST was not sufficient to facilitate online learning. Additionally, the findings indicate that majority of the students and lecturers did not have access to necessary online infrastructure. There lacks a clear policy guidelines for online learning. These findings show that MMUST has inadequate requisite ICT infrastructure and skills to enhance successful implementation of online learning. The study therefore recommends a need for public universities to create partnership with the private sector to improve ICT infrastructure to build the necessary capacity and standardize online learning programs. It further recommends that Institution Policymakers need to formulate policies that promote effective online learning across universities.

On the regional-scale streamflow variability using flow duration curve
Authors: Dey Pankaj , Mathai Jeenu , Sivapalan Murugesu , Mujumdar Pradeep
Published: August 2023

Abstract. As each catchment responds uniquely, even if they appear similar, formulating generalizable hypotheses and using routinely used signatures of catchment similarity to examine streamflow variability can be difficult. Flow Duration Curve (FDC), a concise portrayal of streamflow variability at a specific gauging station, can provide insights into hydroclimatic and landscape processes occurring at a wide range of space and time scales that govern flow regimes in a region. This study explores the suitability of partitioning of annual streamflow FDC into seasonal FDCs, and total streamflow FDC into fast and slow flow FDCs to unravel the process controls on FDCs at a regional scale, with application to low-gradient rivers flowing east from the Western Ghats of Peninsular India. The focus is on investigation of the controls of common regional landscape features (in space) and seasonal climatic (in time) variations on regional variations of the FDC. Findings of the study indicate that bimodal rainfall seasonality and higher fraction of moderate to good groundwater potential zones explains the higher contribution of slow flow to total flow across north-south gradient of the region. Shapes of fast and slow FDCs are controlled by recession parameters revealing the role of climate seasonality and geologic profiles, respectively. A systematic spatial variation across north-south gradient is observed– highlighting the importance of coherent functioning of landscape-hydroclimate settings in imparting distinct signature of streamflow variability. The framework is useful to discover the role of time and process controls on streamflow variability in a region with seasonal hydroclimatology and hydro-geologic gradients.
Decomposition of Pre-β- Irresolute Maps and g- Closed Sets in Topological Space
Authors: M. RAJAB AHMED , Z. ALI DHFAR , A. HADI OHOOD
Published: July 2023

This paper explores the decomposition of pre--irresolute (pre--irr) maps and their connection to generalized closed sets (g-closed) in topological space (top. sp.). We provide the necessary background on top. sp., continuity, closed, and related concepts. We introduce the definitions of pre--irr maps and g-closed and discuss their basic properties. The decomposition theorem is presented, stating that every pre--irr map can be decomposed into a composition of a pre--continuous (pre- -cont.) map and a b-irr map. Examples and applications are provided to illustrate the behavior of pre--irr maps and the practical implications of the decomposition theorem. We examine the relationships between pre--cont. maps and pre--irr maps, exploring the conditions under which a pre--irr map is also -irr, and provide a proof for this relationship. The properties of pre--cont. maps, - maps, g- pre--cont. maps, and g--cont. maps are discussed, along with proofs and examples to illustrate their applicability. This paper contributes to the understanding of pre--irr maps, their decomposition, and their relationships with g-closed, providing a foundation for further research in top. sp. and map decompositions.

COMPUTATIONAL METHODS FOR SELECTION OF FUNCTIONAL MONOMERS IN THE SYNTHESIS OF MOLECULARLY IMPRINTED POLYMER OXYTETRACYCLINE
Authors: Maulidya Selvira Anandia Intan , Suherman Meilia , Angelika Angelika
Published: August 2023

Oxytetracycline is used to treat various disorders in poultry, particularly hens. Their use, however, may be connected with unsatisfactory residual levels in food. Because the generally used method for analyzing oxytetracycline residues is expensive, unique preparation methods such as the Molecularly Imprinted Polymer (MIP) approach have been developed. MIP is one of the most successful pre-analysis preparation procedures for extracting the target analyte from the complicated matrix. The most significant aspect of creating a successful MIP is the selection of functional monomers compatible with the monomer's physicochemical properties and Oxytetracycline as a template. The PyRx and Autodock apps are used in this study to determine the value of the binding affinity and hydrogen bonding created between the functional monomer and the template. According to the study, the monomer 5-[1-(2,3-dimethylphenyl]-1H-imidazole has the lowest binding affinity value (-4.34 kcal/mol), indicating that the Oxytetracycline template will interact well with this monomer.
MARCAS DO QUE SE FOI: UFANISMO E PROPAGANDA NA DITADURA NO BRASIL
Authors: Vieira Fernando , Maurey Andrei , Araujo Thiago
Published: July 2023

The present work proposes to study the role of propaganda in the audiovisual media, TV and cinema, by the Dictatorship in Brazil. The time cut for the production is the 1970s and 1980s. The choice of this period is due to the double context that involved the dictatorial government in Brazil: the defeat of the armed opposition in the military field, reinforcing the modernizing role of the government in social and economic relations, and the need to recompose the bases of support in Brazilian society after the Economic Miracle crisis. Theoretically, what we seek to demonstrate is propaganda as an instrument of persuasion at a time when the use of coercion is wearing thin. Building and reinforcing ties between the government and Brazilian society was one of the objectives of the government's TV and cinema advertisements. For this work, besides articles and books that discuss the theme, the propaganda films of the period will be analyzed. The selection of the films will be made according to previously defined themes. The films are in the National Archive, which has made them available on the YouTube website. The links of each film analyzed will be indicated. Analyzing the discourse that permeates each film allows an understanding of the objectives and proposals contained in the filming. Besides, since its creation at the end of the 19th century we have seen the intersection between cinema and history. We can see that the visual analysis of the propaganda pieces will allow us to dive into the historical context of the time, perceiving the nuances that marked Brazil in the period. Our conclusion will be to demonstrate how the action of propaganda was inserted in the context of the advance of the industrialization of consumer goods, reaching, however, the urban middle segments and failing to broaden the bases of support of the dictatorial government. Constructing the reflection that the present article proposes

Evaluation of Barriers to E-commerce in Malawi using Grey Relational Analysis
Authors: Matambo Ethel
Published: July 2023

E-commerce (electronic commerce) provides a convenient way of buying or selling products online and is a popular choice in certain segments of societies worldwide. The significance of e-commerce has been observed during the COVID-19 crisis, where customer preferences shifted from physical stores to online stores due to lockdowns and social distancing. E-commerce has been observed to be more effective in developed countries than in developing countries such as Malawi due to the difference in the resources required for the sustainability and growth of e-commerce. The current study evaluated the barriers to e-commerce in Malawi and ranked them using the Dynamic Grey Relational Analysis model. Using the primary data collected from the customers in Malawi, the study found that lack of trust in online systems and limited access to cell phones and computers and online payment methods are the most significant barriers. The study found that both human and technical (infrastructure) factors are hindering the growth of e-commerce in Malawi.

The EU Directive 2014/95/EU requires large companies, including those in the energy sector, to disclose non-financial information, such as environmental, social, and governance (ESG) issues, in their annual reports. This has led many energy companies to integrate sustainability and ESG reporting into their overall corporate reporting. However, complying with the directive can present both challenges and opportunities for energy companies. This document aims to analyse the impact of integrated reporting on the value relevance of European energy companies. To accomplish this, we analysed three of the most significant companies in the energy sector: Haliburton, Schlumberger, and Baker Hughes. In their annual reports for the year 2021, each company applied European Directive 2014/95/EU. During the analysis, we paid close attention to the additional information regarding economic, environmental, and social issues. Particular attention was paid to the relationship between financial and non-financial information. In addition to the current condition, we focused on and evaluated the communicated future plans and visions for development in the areas listed below. Due to the application of content analysis, it was possible to assess the corporations using an evaluation matrix.
