НООЕКОНОМІКА ТА ХОЛОНОМНА АКСІОЛОГІЯ КОГНІТАРІАТУ

Досліджуються умови та соціокультурне середовище інтегральної досяжності інтенціональних змістів інтелектуальних продуктів діяльності когнітаріату – холономності аксіологічних патернів свідомості інтелектуальних еліт нооекономіки. Стверджується, що місцем і способом руху досягнення холономності когнітивних змістів аксіологічної ідентичності культурної ментальності суб’єктів нооекономіки виступатиме не суто ринковий, а символічний обмін, де у монетизованій формі залишиться патернальний проект дарунку-у-відповідь. Стверджується, що оскільки тренди цифрових технологій протікають у напрямку досягнення нульових граничних витрат виробництва інтелектуального продукту, то зникають об’єктивні підстави формування ціни ринкової пропозиції, а отже ціновий механізм редукує до суб’єктивної невизначеності встановлення ціни товару. Констатується, що інтелектуальні проекти збережуть трудовий вміст вартості у двох випадках: 1) якщо це будуть технологічно-інженерні проекти із передбачуваним ступенем капіталовіддачі та капіталоємності та 2) якщо когнітивні тексти являтимуть собою не продукти інтелігібельної творчості, а софістичні компетентності організаційних, управлінських, консультативних та освітніх послуг. Постулюється, що холономний принцип аксіологічної континуальності культурної ментальності когнітаріату у вимірах мультиінтелектуально-мережевої актуалізації є ефективним інструментом асиміляції енергії викликів історичних флуктуацій у формі великих і малих “Чорних Лебедів”. Тобто когнітаріат – це той тип “уявлюваної спільноти”, який здатний постійно продукувати у формі мінових вартостей ціннісні патерни відтворення ідентичності завдяки онтологічній новизні створюваних текстів як їх споживній вартості, що й слугує перманентною основою пасіонарної активності. Оскільки у структурі символічного обміну відсутні підстави виникнення суперечностей розподілу (а саме сфера розподілу є першопричиною усіх антагонізмів економічних відносин), то синергетичний ефект самозростання ланцюгів вартості в нооекономіці розширюється, емансипуючи зі сфери виробництва, охоплюючи сферу обміну і споживання у тотальності часового детермінізму – миттєвості, що нагадує євангельський ефект нагодування п’яти тисяч народу п’ятьма хлібами. У цьому полягає суть негентропійної функції когнітаріату в історії початку нової епохи – Свідомої Еволюції ноосферної цивілізації.

BANKING SECTOR REFORMS IN THE MONETARY POLICY SYSTEM
Authors:   Academy of Applied Sciences (WSHIU), Trzonkowski Konrad
Published: January 2024

In the article the efficiency of implementation of reforms in the banking sector in the conditions of crisis is analysed. An analytical study of the implemented measures of reforming the banking sector as a significant component of the country's monetary policy system has been carried out. It is indicated that the banking sector, as the main regulator of the country's monetary policy, keeps the most important blocks of the financial system of the state under absolute control. But at present, the country's economic sector and its banking sector in particular is facing serious threats that require concrete proposals to resolve them. It is specified that the issues of determining the factors and factors that support the country's economy and the search for effective reforms of the banking sector in the monetary policy system are becoming particularly relevant. It is stated that banking crises are an indicator of instability and devaluation of the economy. To avoid their recurrence or mitigate their negative impact, government regulators should develop a mechanism that would strengthen prudential requirements for market participants – financial companies. It is noted that after the reforms of the banking sector of Ukraine in the field of corporate lending in 2016–2017, banks became more willing to provide loans for small amounts, and consequently, the concentration of the loan portfolio decreased. It is noted that the implemented reforms have encouraged banks to pay more attention to the financial condition of debtors, which has allowed to expand access to credit for financially stable clients. It is emphasised that banking sector reform should be the highest priority of the monetary policy system if the country intends to improve and realise its economic growth potential in the coming years. It is concluded that reformation efforts should be aimed at strengthening the supervisory structure, enhancing prudential requirements, increasing transparency of banking operations, management and financial reporting, as well as facilitating the consolidation of fragmented private banks and equalising of the playing field between private and state-owned banks, in particular, given the dominant position of the National Bank and the full guarantee of household deposits in private banks.
Cooperation and conflict in the building and maintenance of the compound nests of monk parakeets Myiopsitta monachus

Published: January 2024

Colonial birds often breed at high density, generating conflict among neighbours over the use of nest-building materials. However, in a few colonial species, breeders appear to cooperate in the construction of compound nests that contain multiple breeding chambers within a single nest structure. The relative contributions of individual birds and the balance between cooperation and conflict among close neighbours in such species have rarely been examined. In this study, we investigated evidence for cooperation and conflict in the building and maintenance of the nests of monk parakeets Myiopsitta monachus in an invasive population in which compound nests are frequent. First, we found that males invested more in nest construction than females and when more than one male occupied the same breeding chamber multiple males contributed to the same nest. Females, by contrast, invested more in nest defence than males. Second, we found that there was conflict among pairs over nest material, with kleptoparasitism of nesting material and defence against conspecifics evident. We conclude that nest-building in monk parakeets involves both cooperation and conflict. Breeders often tolerate the budding of nests, which are often built by relatives, but that pairs are also in conflict over the use of nest material.

After analysing the current literature in the field of mine hoisting, to determine the prospects for the use of disc brakes in a complex of mine hoisting machines with increased rope capacity with a long cylindrical cutter drum. To identify the problems associated with the end runout of the sheath and an increase in the deviation angle that arise when operating drums with a long casing in order to optimise their use. The methods. The study identifies the problems of using disc brakes in combination with long drums of increased rope capacity, as well as the associated increase in the value of the deviation angle and the length of the rope string. A computer experiment was carried out to find the dependence of the end runout of the sheath on its length under the action of a steady external pressure modelling the operation of a coiled rope, using the example of the sheath of the drum TsR-6.75×6.2/1.95. Findings. The article considers the problem of stiffness of long drums of hoisting machines, the increase in length of which occurs due to the increase in the depth of extraction, as well as the use of disc brakes in such hoisting machines. A computer experiment has been conducted to determine the dependence of face runout on the length of the hoisting machine drum shell. Thus, with the lengthening of the shell, the end runout increases, which can interfere with the safe operation of the disc brake. The originality. For the first time, a calculation methodology for determining the axial stiffness of long drums of mine hoists with increased rope capacity was developed and substantiated using the example of the drum of the TsR-6.75×6.2/1.95 machine with the help of the SolidWorks and MathCAD software complex. Generalisation of data on the relationship between drum length and deviation angle, which are critical for the safety and efficiency of mine hoists. Practical implementation. The implementation of the methodology will solve the problems with the use of disc brakes in the complex of mine hoists with long cylindrical drums of increased rope capacity, namely, with the end runout of brake discs, as well as an increase in the value of the deviation angle, increasing the efficiency and safety of mine hoists. This will eliminate the need to install additional support supports when lengthening the rope string to prevent longitudinal and, as a result, transverse vibrations. Ensure more stable and safe operation of mine hoists by optimising the design and braking systems.

Authors: Klymenko A , Sazanishvili Z
Published: January 2024

Purpose. In order improving the tribotechnical properties of the surfaces of parts, a progressive method is the application of a polymer coating on a relatively cheap metal material. When choosing polymers for use in friction nodes, it is important to evaluate their properties, namely strength, heat resistance and wear resistance. In the technological process of applying coatings, the adhesion of polymers is a significant characteristic. The condition of the surface of the substrate and the viscosity of the polymer material should be attributed to the conditions affecting the formation of the adhesive contact. The purpose of this work is a detailed study of the influence of the nature and microrelief of the surface of the substrate on the adhesion ability of meta-aramid itself. The methods. To achieve the goal, a coating was applied to metal plates made of carbon steel St3 and copper alloy M1, the roughness of the surfaces of which was changed with the help of abrasive grinding wheels. The starting material of the coating in the form of a finely dispersed powder was dissolved in dimethylacetamide. A coating with a thickness of 80...100 μm was formed by applying a solution of meta-aramid on the surface of a metal substrate, followed by evaporation of the solvent in a drying cabinet at a temperature of 150...160ОС for 45...50minutes. To determine the strength of the adhesive joint of the meta-aramid coating from the surface roughness of the steel and copper substrate for different concentrations of the polymer solution, mathematical processing, approximation and extrapolation, experimental data were carried out in the work. Findings. The influence of the microrelief of the surface of metal substrates and the viscosity of the polymer solution on the adhesion ability of meta-aramid coatings was investigated. The optimal parameters of the roughness of the substrate and the concentration of the polymer solution were determined using the method of mathematical modeling. The originality. The relationship between adhesion indicators and the roughness of metal surfaces has been established. It helps to form recommendations regarding the parameters of the surface roughness of the substrate to ensure adhesion of the coating. Practical implementation. The application of polymer coating technology allows to increase the performance of parts in friction nodes, using relatively cheap metal materials for their manufacture. The obtained results form recommendations regarding the roughness parameters of the substrate surface and the concentration of the polymer solution.
Integrated approach to analyzing the stress-strain state of the tubbing erector manipulator mechanism based on the SolidWorks program
Authors: Panchenko O
Published: January 2024

Purpose. The research purpose is todevelop and substantiate a method for computer analysis of the stress-strain state that occurs in the tubbing erector manipulator mechanism with several degrees of freedom, using modern computing complexes based on the finite-element method. Methods. The research uses software complexes, with the help of which a calculation-theoretical apparatus has been created, which is intended for calculating dynamic and static loads that occur in the elements of the tubbing erector manipulator mechanism. The results of modeling the stress-strain state in the parts and nodes of this mechanism, obtained using the SolidWorks Motion and SolidWorks Simulation programs, have been compared. The errors in these results have been estimated. Findings. The effectiveness of the proposed analysis method, based on the combination of SolidWorks applications, in particular, SolidWorks Motion and SolidWorks Simulation, has been proven on the example of modeling the most complex design of the UT62 tubbing erector mechanism.The essence of the method is that initially, using the SolidWorks Motion application, the laws of motion of the motors are set. The tubbing erecting process itself is divided into discrete moments of time with the selection of parts in which the stress fields are calculated and with the determination of the maximum equivalent stress, using the Simulation Setup tool. The change in these stresses during the erecting cycle is analyzed, and if it is necessary to refine the data, the discrete time step of the mechanism motion is reduced. Specific information about the stress-strain state of the part is obtained in the SolidWorks Simulation application, using data imported from the SolidWorks Motion program about gravitational and inertial forces that occur in the tubbing erector mechanism. Originality. The scientific novelty of the developed method of computer analysis for the mechanism of the manipulator of the UT62 type tubing stacker is manifested in a comprehensive approach to modeling the stress-strain state, which includes the integration of data from SolidWorks Motion and SolidWorks Simulation programs for accurate determination of stresses, taking into account both gravitational forces and dynamic loads, which ensures high accuracy and complexity of calculations in real operating conditions of the mechanism. Practical implications. The proposed method can be used for modeling the motion of mechanisms of different complexity, in particular, in the design of domestic tubbing erectors.

Published: January 2024

Purpose. Establishing a dependency of change in a stress-strain state for a rubber-cable tractive element with broken structure due to rheology of a rubber shell. Methods. Analytical solution of a model of a rubber-cable tractive element with a broken structure due to rheology of a rubber shell. Results. An algorithm for determining a stress-strain state of a rubber-cable tractive element with a broken structure due to rheology of a rubber shell is developed. The suggested algorithm involves splitting the rope into two parts, which allows considering the influence of a dependency of shear modulus on deformations in a form of a broken line constructed of two segments. Splitting the rope in the area of integrity breakage into three or more parts allows considering a more complex dependency of shear modulus on shear deformations. A mechanism of changing a stress-strain state of a rubber-cable rope due to rheology of a rubber shell is established. The local influence of changes in properties of elastic material interacting with a damaged cable on a stress-strain state of a rubber-cable tractive element with a broken structure is analyzed. Scientific novelty. A mechanism of influence of a shear modulus of rubber shell material in the rubber-cable rope (belt) with a cable integrity breakage on stress-strain state of composite tractive element is established to be time-varying and nonlinearly dependent on deformations. Practical significance. Consideration of shell rubber rheology makes it possible to predict a rope stress state considering a non-linear law of changes in properties of rubber during its use and to increase safety and operational reliability of rubber-cable tractive elements. A local change in mechanical parameters does not increase the danger of using a rope with continuity breakages of cables. An increase in lengths of redistribution of forces and displacements requires an increase in length of steps in butt-joint connections.

Consumption of aflatoxin contaminated foodstuffs can cause acute or chronic toxicity in humans. With an aim to protect public health, maximum residue levels (MRLs) for these toxins are defined by the regulation authorities. To control the compliance of aflatoxin residues in cereal-based products to legislation, a convenient analytical technique that will provide rapid, specific, accurate and costly effective analysis such as ELISA method is required.
In this study, concentration of total aflatoxins in twelve cereal processed products supplied under random selection from several retail outlets in Republic of North Macedonia was determined using commercially available RIDASCREEN Aflatoxin total kit. Analyses have shown that none of the examined samples contained aflatoxins above the MRLs (4 μg/kg). According to the obtained results, the ELISA method can be used for routine detection and quantification of total aflatoxins in cereal products due to simplicity, specificity and sensitivity. In addition, this study may initiate the use of immunochemical methods for analysis of potential aflatoxin contamination in order to establish data collection for the presence of these concerning toxins in cereal-based products available on the national market.

Limited effects of management and ecological subsidies on the size-spectra of kelp forest fish communities
Authors: Gartenstein S , Pérez-Matus A , Heather FJ , Godoy N , Torres-Cañete F , Catalán AM , Valdivia N
Published: January 2024

Animal body size influences key ecological processes across biological hierarchies. For instance, densities (N) and community biomass (B) are allometric functions of body mass (M). Energetic equivalence predicts that density scales with body size as N ∝ M-0.75 and that biomass scales with body size as B ∝ M0.25. However, the way fish size-spectra are influenced by external processes, such as ecological subsidies (e.g. nutrients from upwelling zones) and fisheries management, is not well understood. We investigated the relationship of body size with density and biomass of reef fishes associated with subtidal kelp forests of Lessonia trabeculata that were influenced by the separate and interactive effects of management (Territorial Use Rights for Fisheries [TURF] or open access) and upwelling regimes (upwelling or non-upwelling zones). Fish densities and lengths were recorded using underwater visual censuses. Within each of 4 locations, paired TURF and open-access sites were surveyed. We surveyed 18 fish species, encompassing 1511 individuals ranging between 2 and 6639 g. We observed that fish size-spectra deviated from energetic equivalence, as N ∝ M-0.32 and B ∝ M2.2, indicating that the contribution of large-sized fishes to community density and biomass was greater than that predicted by energetic equivalence. Multi-model inference suggested that TURF and upwelling scenarios had weak effects on fish size-spectra. Results indicated that fish communities may have access to external food sources beyond local kelp forests. In addition, size-spectra may be a spatially persistent attribute of these fish communities.
Two Friends : Circumstances of a Historic Feminist Collaboration
Authors: Zahos Zachary
Published: January 2024

Foregrounding the collaborative nature of film production, this chapter moves beyond an auteurist paradigm to consider the shared production process between Campion and two key creative agents: screenwriter Helen Garner and producer Jan Chapman. As one of Australia’s most respected authors, Garner’s influence on both Two Friends (1986) and Campion’s development as an artist has not been extensively studied. Nor has the influence of Chapman on Campion, who collaborated again on The Piano (1993), been documented. Zahos’ chapter documents how three of the Antipodes’ most important female creative practitioners met, collaborated on, and influenced one another after making Two Friends. In addition, the chapter explores the extensive distribution history of the film and considers the formal construction of Two Friends, arguing that even as it demonstrates Campion’s ability to tell emotionally resonant, female-centred stories through an unorthodox approach to style and narrative structure, the film remains an undervalued and understudied work in Jane Campion’s oeuvre. Two Friends should, Zahos contends, occupy a more prominent place in narratives of the development of Jane Campion as both artist and international “auteur.”
Jane Campion’s Palimpsestuous Gothic: Kinship in Top of the Lake: China Girl
Authors: Schmertz Johanna
Published: January 2024

Schmertz’s chapter explores Top of the Lake: China Girl (2017) as a consideration of the incest taboo and the traffic in women that manifests it, framed by the work of Gayle Rubin (1975). If, Schmertz argues, Rubin critiques the practice of mapping law and culture onto sexuality and female reproduction through incest taboos, Campion’s exploration of the outsourcing of reproduction through surrogacy deepens Rubin’s assertions. With the theme of surrogacy, the cultural goal of exogamy established by the incest taboo is exploded from within by Campion, in what the director calls an ‘ovarian’ rather than ‘feminist’ practice (Vineyard 2017). Schmertz argues that Campion thus takes us back to a non-differentiated, pre-civilized space, harnessing the disruptive potential of Gothic themes. In this way, China Girl critiques social structures created through exclusion and division rather than attachment, proscription rather than connection. In the ocean’s ebbs and flows, in its liminal spaces that signify birth and return to origins, Schmertz argues Campion’s ‘mother’ returns to threaten patriarchal structures in order to reclaim her child. The director’s palimpsestuous approach to exploring the family, according to Schmertz, explodes kinship structures, so that new ways of ‘making kin’ can occur.
Afterword: Unsettling Feminism
Authors: Cooper Annabel
Published: January 2024

This afterword considers The Power of the Dog and takes up the themes traversed throughout this volume in a consideration of Campion’s latest work. In Cooper’s view, the film invites further exploration of the already uneasy sexual politics in Campion’s work and Cooper’s afterword provides detailed attention to embodiment, which is central to the film’s elaboration of power. In addition, the afterword addresses Antipodean feminist critics’ disquiet over indigenous representation in light of The Power of the Dog’s adaptation from Thomas Savage’s 1967 novel of the same name, a criticism sometimes levelled at Campion’s work.
Marx between East and West: The Karl Marx Statue in Trier as an Example of Intercultural Failure?
Authors: Soffel Christian
Published: January 2024

This chapter deals with the erection of a Karl Marx statue in the German city of Trier in 2018 and, thus, with a very recent example of cross-cultural misunderstandings. Presented as a gift by the Chinese authorities to Marx’s German birthplace, the statue was erected to commemorate the 200th anniversary of the philosopher’s birth in 2018. As Soffel shows by tracing in detail both the Chinese and the German reactions to this gift, the exchange of such a present is inextricably linked to culturally motivated assumptions that may give rise to irritations. Studying Chinese source material, Soffel unravels the official Chinese perspective on the statue and juxtaposes it to the debate in Germany which centred on practical concerns regarding the size and location of the statue as well as on
more general fears of the gift serving Chinese propaganda purposes. By closely following the processes that eventually led to the erection of the statue, Soffel draws attention not only to cultural differences but also to structural ones when a German local authority finds itself dealing with the official Chinese state apparatus.
Abject Pleasures in the Cinematic
Authors: Kerner Aaron
Published: January 2024

This chapter outlines the scope of the book. It examines the various efforts to theorize the affective experience, and makes efforts to assimilate and synthesize a range of methodological approaches.
On the Beautiful
Authors: Kerner Aaron
Published: January 2024

This chapter theorizes the experience of the beautiful, drawing heavily from Kant. The beautiful is a pleasurable feeling, and has nothing to do with what is (morally) good, or agreeable.
Musicality
Authors: Kerner Aaron
Published: January 2024

Music, or something approaching music, such as the musiscalization of the voice in poetry, or the musicalization of the image, possesses the ability to affect us—to elicit goosebumps, tears.
Pornography
Authors: Kerner Aaron
Published: January 2024

The pornographic genre is littered with regressive content. Despite this, the genre still possesses an affective charge capable of eliciting sexual excitation. This chapter examines pornographic choreography and its allure.
On Laughter
Authors: Kerner Aaron
Published: January 2024

This chapter examines the various approaches to laughter. While the presumption is that laughter is associated with comedy (which is explored), the fact is that we laugh for many reasons—for example, to ward off disgust, the abject.
Body Humor
Authors: Kerner Aaron
Published: January 2024

This chapter examines dick pics—specifically how dicks appear at inopportune moments in cringe comedy. It also examines the grotesque body as found on the Tosh.0 program focusing on Ricky Berwick’s appearance on the show.
Conclusion
Authors: Kerner Aaron
Published: January 2024

This chapter reviews the arguments in Abject Pleasures. It also showcases an experimental exercise, where Kerner utilizes his “sense survey” to “measure” the affective experience of a film in a large classroom/theatrical setting.
Introduction
Authors: Botting Josephine
Published: January 2024

The introduction sets out the book’s ambition to bring new insights into Adrian Brunel’s work. A survey of the production landscape and a brief history of British cinema establishes the background to Brunel’s career with reference to key figures and legislation. An overview of the literature on and around the subject sets out to define the place this book will occupy in the existing studies of the period. The introduction outlines the book’s approach, with reference to new methods of studying film history and ways of employing archival research. Ways to employ auteurism for directors with less conventional careers are examined. Using various archives it demonstrates how Brunel’s work sheds light on the wider context of British cinema and culture of the 1920s through an analysis of his films and the various production contexts in which they were made. This opening chapter justifies the choice of Brunel as a subject, a maverick figure who carved a unique path through the industry, kept a vast archive of all his papers and, crucially, ensured the preservation of his own films.
