Published: March 2024

The author analyzes new methods, approaches, and ideas for further development of image encoding to increase informativeness and reduce computational complexity. An architecture (a set of adaptive encoding modes with minimal computational expenses for selecting and switching between them) for a simplified high-speed codec is developed. Simple universal algorithms for predicting pixel values based on external data and using values of neighboring blocks are proposed. A modification of MSE (shifted MSE) is proposed, which more accurately reflects contour distortions. A one-norm simplified cosine transform of order 16 with low computational complexity is proposed. A new algorithm for adaptive use of transforms of different types and orders depending on the compression coefficient is given. Keywords: simplified high-speed codec, adaptive coding modes, pixel value prediction algorithms, error estimation algorithms, transform informativeness, simplified cosine transforms, fast algorithms.
Entrepreneurship: A Potential Tool to Combat Inflation
Authors: Das Ripan
Published: March 2024

The risks that inflation poses to economic growth and stability call for creative solutions. In this essay, we look at how entrepreneurship might help ease economic inflation. The role of entrepreneurs in fostering economic expansion, more employment opportunities, and higher output is explored. The article examines the role of entrepreneurship in promoting innovation, which in turn can lead to the creation of new products and services that improve competition and hence alleviate inflationary pressures. The importance of free markets in containing inflation is also emphasised, with an emphasis placed on the role played by entrepreneurial spirit in fostering an environment where prices are kept low. This article looks at how higher production and more effective resource allocation- both results of entrepreneurship's impact on the supply side of the economy- help keep inflation in check. Case studies of prosperous businesses that had a beneficial effect on inflation dynamics are used to examine the feasibility of entrepreneurship as a response to high inflation rates. Sensitivity to business cycles, risk and failure, market concentration, and access to financing are only some of the issues that are critically discussed in the context of employing entrepreneurship as a strategy to combat inflation.

Published: March 2024

An empirical investigation on the acceptance of Chinese mining activities in rural Zimbabwe was done for this article. Its two main goals were to: (1) assess public opinion of Chinese mining operations; and (2) present a workable investment model that takes into account the main locals' complaints. Additionally, it touched on two related issues of concern: (i) what causes host community disputes with foreign mining companies in rural Zimbabwe, and (ii) what investment model may be used to settle host community disputes between investors and host communities?. It then assessed Chinese mining investments against the 3Ps of the Triple Bottom Line theory (TBL). Created by John Elkington in 1994, TBL recommends a balance between people, profitability and the planet (environmental conservation) in business operations. Based on the study's somewhat negative findings, the article created the PESE investment model (short-cut for people, environment, social and economy) which it is presenting as an ideal framework that may have broader application for sustainable investment in Zimbabwe's mining industry.

Gender diversity management in NATO for sustainable security and peace
Authors: Trochowska-Sviderok Kamila , Masakowski Yvonne Rose , McFate Montgomery , Holohan Anne
Published: March 2024

The article focuses on the need for a paradigm shift in diversity management for sustainable peace and security. We discuss the bidirectional influence of security and defence organisations and society; the intersectionality of issues related to social justice, health, race, and ethnicity; sexual abuse and exploitation; and cultural factors that influence the functioning of LGBTQ+ personnel and the gender/technology nexus in the context of North Atlantic Treaty Organization (NATO). During the application of the Sustainable Security Paradigm to gender diversity management, we found that ecofeminism and the ideas of post-colonial theory should inform the transformational shift of contemporary security and defence organisational cultures. This approach was used by the multinational NATO Science & Technology Organization Exploratory Team ET-197 Gender, Peace and Sustainable Security (2022-23) and its successor, the NATO HFM-368 Research Task Group (2023-26). Our research efforts were triangulated by an analysis of doctrinal textual, audiovisual and art sources that relate to gender diversity and its management. Given the complexity of future warfare, there is a strategic imperative to develop an inclusive defence strategy that reconfigures the traditional white male-focused military paradigm. It is evident that the root cause of gender inequality cannot be solved solely by doctrine and training solutions—rather a transformational organisational culture shift is pivotal and critical to the future global security. This is the first article that addresses the issues of gender diversity management for sustainable security and peace in an interdisciplinary and holistic manner. Our approach is relevant to any organisation with internal gender and intersectional diversity and systemic discrimination.

Authors: Kwon I. H. , Choi Y. J. , Ide T. , Takahashi K. , Noda T. , Sawada K.
Published: March 2024

Portable wavelength detection systems have been developed for various environmental and biochemical applications. Conventional systems have some limitations as they are unable to adapt to changes in wavelength and rely on optical filters or slits to distinguish between different wavelengths. To address these limitations, a filter-free wavelength sensor system was proposed, utilizing the absorption coefficient of silicon to identify wavelengths. The proposed system comprises an analog circuit for measuring photocurrent from a filter-free wavelength sensor, integrated with a temperature sensor and microcontroller for signal processing. The proposed system can measure currents with a resolution of 1.2 pA within a 30 nA range, achieving a coefficient of determination of 0.999 for measured currents in relation to light intensity. The microcontroller features a temperature compensation algorithm, enabling wireless control and data transmission. Applying temperature compensation reduced the rate of errors in the data by 61%. By eliminating the need for optical components, a wireless measurement system was developed that can accurately identify wavelengths.

Published: March 2024

The molecular size of an alkaline cation has been reported to affect the dissolution of resist film in an alkaline aqueous solution. However, the details are still unclear. In this study, the dissolution dynamics of poly(4-hydroxystyrene) (PHS) in potassium hydroxide (KOH) and sodium hydroxide (NaOH) aqueous solutions were investigated to clarify the effects of small alkaline cations on the dissolution dynamics of typical backbone polymer for chemically amplified resists by a quartz crystal microbalance (QCM) method. The temporal changes in the frequency and impedance of QCM substrates during development were measured. The maximum impedance reachable during development significantly exceeded that of the developer saturated with PHS, unlike the case of tetramethylammonium and tetraethylammonium cations. This means that the PHS matrix near the surface was swollen by decreasing the size of the alkaline cation. By either increasing or decreasing the size of the alkaline cation from tetramethylammonium and tetraethylammonium cations, the transient swelling layer became thick.

Issues regarding women are still widely discussed by the general public, so there are several individuals who take advantage of these issues to gain personal gain. Women who are victims of sexual harassment have been judged badly by society because their disgrace has spread widely and has always become a hot trending topic in magazines, newspapers, television and social media. Therefore, researchers really want to examine the thoughts of an Indonesian academic, namely Nadirsyah Hosen, regarding women's morals as stated in the QS. An-Nur: 31 in ”Tafsir Al-Quran di Medsos: Mengkaji Makna dan Rahasia Ayat Suci pada Era Media Sosial”. This article uses qualitative methods with descriptive analysis, literature review and a thematic approach. The primary data in this article comes from the Al-Qur'an and the book “Tafsir Al-Quran di Medsos: Mengkaji Makna dan Rahasia Ayat Suci pada Era Media Sosial”, for secondary data using several books and journals that are appropriate to the discussion. This article explains how women’s morals are in this modern era, with the aim that women, especially teenagers, can return (again) to the correct religious sharia. Researchers concluded that it is mandatory for women to wear a large khimar (cover) that covers their chest and forbids women from offering tabarruj to men who are not their mahram.

Modeling of the plywood making process glued with thermoplastic polymer
Authors: Kozak R.O. , Kusniak I.I.
Published: March 2024

A promising variety of the wood composite materials is plywood glued with thermoplastic polymers. However, making such a wood composite requires adjustment of the pressing modes, because there is a slightly difference between the hot method of the veneer packages pressing glued with thermoplastic films and the method of the veneer packages pressing glued with thermosetting adhesives. Among the main processes that occur in the gluing plywood process are heat and mass transfer. The availability of the thermoplastic film between the veneer sheets is going to change the thermal conductivity of the package, and therefore will affect the pressing duration. If suppose, that the package has a plate appearance, which is located between heated to the certain temperature pressed plates, then the known Fourier-Kirchhoff thermal differential equation can be applied. The basis for the model development of the warming package veneer process glued with thermoplastic film are laid methods of nonlinear programming, uniform search and conjugate gradient. On the offered mathematical model basis, the temperature field change in the package thickness during the plywood gluing with plastic film is calculated, the calculation of the warming duration indicators of the package veneer is done and this indicator dependence on the thermoplastic film flow rate and the pressing temperature is established. The duration of the warming package veneer glued with thermoplastic film depends on the temperature at which the thermoplastic polymer will change from a highly elastic to the viscous state. The transition of the thermoplastic film LDPE to the viscous state begins at 125оС and lasts up to 240 оС. With increasing of the press temperature plates from 140 to 180оС the duration of warming up the middle of the package to 125оС decreases by 89% for all investigated polymer costs is established. Changing the polymer content in the package does not significantly affect the duration of its warming. With increasing of the thermoplastic film flow rate from 130 g/m2 to 190 g/m2, the duration of warming up the middle of the veneer package to 125оС increases slightly from 3,8 to 4,2% depending on the pressing temperature. Suggested mathematical model allows to set the material parameters and plywood pressing mode influence on the duration of the warming package veneer while plywood making glued with the thermoplastic film LDPE.

Published: March 2024

It is known that after continuous logging in the process of machinery during the harvesting of wood and mechanized soil preparation for the creation of forest crops of common oak, there is a violation of vegetation. The composition of the grass and shrub cover of forest areas is changing dramatically, so the study of the dynamics of the similarity of the floristic composition of plant communities at the site of continuous fellings and throughout the period of growth of oak plantations is relevant. The research was carried out on forest areas in the conditions of fresh co-soils of the state forestry enterprises of Central Polissya for which full geobotanical descriptions were made. It is established that within 1-3 years after continuous felling of submenopausal phytocenoses of oak forests in fresh soils of Central Polissya, which, for the most part, are buckthorn-lily-of-the-grass or mixed-grass-lily of the valley, dynamic plant groups begin to form. and meadow species leaving light-loving forests. In such phytocenoses, there are significant differences in the floristic composition of the grass-shrub layer in comparison with the composition of the same layer in the mother plantation. This condition is observed before the closure of the crowns and the formation of its own tent planting. Then there is a gradual restoration of the floristic composition of the grass-shrub tier, the species similarity of plant communities according to the Sorens-Chekanovsky index increases to 0.72 (compared to plantations 20-40 years of age) and to 0.66-0.68 compared to floristic composition of 80-110 annual plantations of oak. After 40 years of age, in the oak groves of fresh sogruds of Central Polissya, the floristic composition of plant groups is almost close to the composition typical of the grass-shrub layer of subclimax mother plantations.
Deve-se usar o fogo como instrumento de manejo no Cerrado e Campos Sulinos?
Authors: Fidelis Alessandra , Pivello Vânia Regina
Published: March 2024

O fogo é um importante instrumento de manejo em diversos ecossistemas, no mundo todo. No Brasil, particularmente o Cerrado e os Campos Sulinos são submetidos a queimadas periódicas, seja por motivos naturais (raios) ou por ações humanas. Entretanto, nas unidades de conservação que se propõem a conservar esses biomas, procura-se impedir a ocorrência de queimadas. Pretendemos aqui evidenciar a importância do fogo no Cerrado e nos Campos Sulinos e estimular uma reavaliação do manejo em relação ao fogo nesses ecossistemas. Evidências fósseis e palinológicas demonstram que tanto o Cerrado como os Campos Sulinos evoluíram com eventos de fogo, pois diversas adaptações são reconhecidas na vegetação e também em seus processos ecológicos, havendo indicações seguras de que sua própria manutenção seja dependente de queimas periódicas. A decisão de banir o fogo nas áreas protegidas com esses ecossistemas traz diversos problemas Ã s próprias unidades de conservação, como exclusão de espécies, invasão por espécies exóticas, perturbação de ciclos ecológicos, que comprometem a preservação da diversidade biológica em médio e logo prazo. Incêndios de grandes proporções têm ocorrido em áreas protegidas de Cerrado nos últimos anos, especialmente causados pela combinação do acúmulo de biomassa e usos das terras no entorno das unidades de conservação. Sendo assim, sugerimos que os órgãos ambientais brasileiros revejam sua posição em relação ao manejo de unidades de conservação que protegem ecossistemas adaptados a distúrbios de fogo, admitindo a aplicação de ações planejadas e controladas que supram os efeitos causados por esse distúrbio natural.Â
Por que é importante entender as inter-relações entre pessoas, fogo e áreas protegidas? Why it is important to understand the relationship between people, fire and protected areas

Published: March 2024

O fogo e seus impactos sobre a biodiversidade e os recursos naturais tem se destacado nas discussões ligadas ao manejo das áreas protegidas. De outro lado, a viabilidade das unidades de conservação como locais de proteção da biodiversidade a longo prazo depende diretamente dos processos sociais e ecológicos que se dão em seu entorno, o que inclui o fogo. Na presente revisão, analisamos o tema buscando um maior entendimento a respeito do que determina o uso do fogo, assim como seu abuso pelas pessoas, e as soluções encontradas por elas para o manejo das vastas paisagens circunvizinhas Ã s áreas de proteção. A tese defendida é a de que para haver efetivo controle do fogo e de seu uso é preciso que pesquisas multidisciplinares analisem as motivações e as formas de uso do fogo no contexto das realidades locais. Além disso, para que ocorram mudanças reais nesse cenário, são necessárias abordagens e metodologias participativas que enfoquem a experiência e os saberes de todos os atores sociais envolvidos na questão.

No Brasil, pouco se conhece sobre a dinâmica dos incêndios em regiões como a Chapada Diamantina, Bahia, onde há a predominância de campos rupestres. Neste estudo, a recorrência dos incêndios no Parque Nacional da Chapada Diamantina é avaliada no período entre 1985 e 2010. Com base nos dados sobre a ocorrência de incêndios, foram determinados sítios com diferentes regimes de queima onde se realizaram levantamentos fitossociológicos. Além dos procedimentos usuais neste tipo de levantamento, a vegetação foi dividida em três componentes: graminóides, herbáceas e arbustivo-arbóreas. Testes de correlação foram realizados, para verificar se há relação entre a cobertura por estes elementos em cada sitio e o tempo decorrido entre os incêndios. Os resultados obtidos demonstraram que 59,41% do parque foram atingidos por até quatro eventos de incêndios no período considerado, enquanto 1,01% foram atingidos por cinco a nove eventos de queima. Os ambientes onde os incêndios na vegetação não foram registrados incluíram áreas elevadas entremeadas por vales profundos de rios ao norte da cidade de Mucugê. Outras áreas não afetadas por incêndios incluíram florestas estacionais e alguns campos rupestres ao sul e ao leste da cidade citada. O mapa sobre o tempo decorrido desde a última queima mostra que as maiores extensões afetadas no intervalo de tempo que inclui a temporada de 2008 (três a quatro anos), quando 41,93% do parque nacional foram queimados. A análise fitossociológica mostrou uma baixa similaridade entre as áreas e permitiu correlacionar as diferenças encontradas com as fitofisionomias dos sítios amostrados e aspectos edáficos. Apenas o componente graminóide teve sua cobertura média fortemente correlacionada com o tempo médio entre os incêndios (F = 324,7204; r = 0,9969; p = 0,0021). Os resultados obtidos mostram que há uma grande variação no regime de queima entre as diversas áreas do Parque, o que tem implicações para seu manejo. Em áreas onde os focos são menos comuns, o combate direto pode ser recomendado. Em áreas com maior recorrência, a adoção de medidas de controle pode ser mais eficaz. A coincidência observada entre a grande recorrência de incêndios e a ocorrência de sempre-viva-de-mucugê (Comanthera mucugensis (Giul.) L.R. Parra & Giul.) indica a necessidade de medidas adicionais de proteção e pesquisa sobre esta espécie e ecossistemas associados.Â

Defining Best Available Technique Performances for Urban Wastewater Plants: A French Application
Authors: Villot Jonathan , Laforest Valérie
Published: March 2024

The treatment of wastewater (WW) and the resulting sludge in urban WW treatment plants (UWWTPs) is accompanied by a significant consumption of resources as well as the concomitant emission of pollutants into the environment. One of the objectives of the NEXT (next generation of wastewater treatment plants) project is to identify sufficiently long-term optimization opportunities for processes to be selected as best available techniques (BATs) within the meaning of the industrial emissions directive (IED). The methodological framework used in this article is based on multi-criteria statistical tools, processing data from industrial plants to classify the sites studied and identify the reference plants in order to propose BAT references and associated emission levels that are reachable. Two public databases available on the internet were used, and 1,010 plants served as samples. The application and results demonstrated the applicability of the methodology and validated the mathematical approach used, as the thresholds comply with current French and European regulations. In the framework of the analysis conducted, five techniques (membrane bioreactor, bacterial bed, sand filter, and high-load or medium-load activated sludge) were identified as BAT according to the range of regulatory classification requirements for WW treatment plants (WWTPs). In addition, an example of reference values that may constitute a possible basis for the regulatory thresholds has been proposed. In parallel, a few discussion points were identified, including the choice of the metric for the reference values, the lack of data for the sludge line limiting identification of the BATs to the water line alone, the approximate characterization in the databases of certain parameters, as well as the problem of technique coupling due to the identification of one main technique.
Shut Up and Listen
Authors: Knaus Chris
Published: March 2024

Less than fifty percent of African American students graduate from high school. Their educational failure is built into the racial structure of curriculum, standardized testing, teacher preparation programs, and even teacher recruitment pathways. Shut Up and Listen argues that African American students should be taught to navigate and resist the racism perpetuated in every aspect of society and schools, and that to do so requires the development and expression of a culturally-rooted voice as a foundation for multicultural, multilingual, democratic communities. Shut Up and Listen focuses on the voices, perspectives, and experiences of urban African American students – and on their writing, to remind educators of the power of voice, and how far schools are from addressing the reality of racism.
Modeling the Operation of a Technological Chain with Vertical and Horizontal Relationships of Participants and Taking into Account Demand
Authors:   Novosibirsk State University of Economics and Management (NSUEM), Lyubyashenko Sofia N.
Published: March 2024

The subject of the article is the study of production structures consisting of a set of independent firms (enterprises interacting with each other through the supply of products through horizontal and vertical links in a single production and technological chain. It is assumed that firms at different levels of the chain not only supply components up, but also sell them on the market, organizing interaction with wholesale buyers. The mechanism of interaction takes into account economic interests, the demand for the company’s products in the market and reflects the situation of equilibrium. The scientific novelty of the study is the deepening of the methodological basis for describing the interaction of participants in the technological chain using matrix modeling based on the principles of constructing matrices of intersectoral balance. Such characteristics of firms and the system as a whole as: final product, gross product, resource volumes are considered. On the basis of the obtained final formulas, the dependences of the economic characteristics of the activity of firms and the system as a whole on the decrease (increase) in prices for resources, on changes in demand are established. The proposed approach to determining the final product of the system seems to be quite reasonable: firstly, the output volumes of the system are linked through the interaction of the manufacturer and seller, taking into account market demand, and, secondly, the volume of sales reflects the economic interests of the parties. The ratio “the price of products on the market – the volume of supply” becomes justified on the part of the demand function (the end consumer), the seller and the manufacturer of products. Such an optimization approach to determining the results of interaction promptly takes into account changes in the market environment and adjusts the performance indicators of participants in the direction of their consistency, which makes it possible to increase the stability of the system. It is established that when the market situation worsens as a result of rising prices for factors of production or a reduction in effective demand, there is a percentage decrease in final output in value terms, but the rate of its reduction is lower. The case of a decrease in demand has a more negative impact on the economy of the firm and the entire system. Thus, the growth rates of the economy and the well-being of the population are determined by the efficiency of complex hierarchical structures with horizontal and vertical relationships.
Tasks of Corporate Conflictology
Authors:   Synergy University, Osipenko Oleg V.
Published: March 2024

The work examines important aspects of the organizational constitution of the priority of corporate conflict management at Synergy University. The author emphasizes that the creation of the Center for Corporate Conflictology at the University is a landmark event, marking the transition to a new stage in the development of this branch of science. The article analyzes in detail the goals and objectives of corporate conflictology, including analytical design and scientific and applied demonstration of realistic representations of agents of investment practice and business processes. The work proposes a thematic plan for a course in corporate conflictology for business owners, developed by the author, designed for 80 academic hours. The author also discusses methods of teaching and implementing a corporate conflictology course into the educational process, including the use of case-study and interdisciplinary research. The author postulates that corporate conflictology and corporate governance in general are based on a wide cycle of knowledge covering various industries. Thus, the article emphasizes the importance of an interdisciplinary approach and knowledge exchange in the field of corporate conflict management. At the same time, the work describes two types of ensuring the interdisciplinarity of the field of knowledge: 1) a mechanistic, textbook approach with episodic and systematic “mutual information” of related subjects; 2) a truly integration approach with theoretical and methodological work on the unification of interpretations and “mutual integration” of knowledge. It is emphasized that for the current stage of development of corporate conflictology, the path of mutual integration of knowledge rather than mutual information is more effective. This justifies the importance of unified interpretations and processes of mutual integration of knowledge for the development of corporate conflictology. An interdisciplinary approach helps students develop the comprehensive knowledge and skills necessary to work in the field of conflict management in a corporate environment. The author calls for testing this methodology in educational institutions in order to enrich the educational process and prepare students for real challenges in the field of corporate conflict management. The author highlights the challenges and problems faced by supporters of the development of corporate conflictology, and also analyzes criticism of this branch of science. In conclusion, the importance of developing corporate conflictology and its potential contribution to the understanding and management of corporate conflicts is emphasized.
