Analysis of methods for accounting cargo vehicles in traffic flow of a regulated crossroad
Authors: Donchenko V. V. , Shumskiy A. N.
Published: July 2023

Introduction. The formation of a ‘cargo frame’ around large cities leads to a change in the composition of the traffic flow on bypass roads, and an increase in the total traffic flow of trucks of various categories. In addition, the active development of suburban areas with residential complexes contributes to an increase in traffic. The totality of the reflected phenomena leads to the emergence of a certain kind of transport problems, primarily associated with a decrease in throughput. Quite often, such problems are observed at regulated intersections, which requires a prompt change in the control mode; for this, the necessary measure is the mandatory consideration of the technical and dynamic parameters of trucks, which are not fully taken into account in the existing reduction factors. In order to establish the degree of influence of these parameters on the change in the main characteristics of the traffic flow, such as the average travel time and average speed, this study was carried out.

Methods and materials. When performing the study, the methods of natural observation, statistical analysis and modelling were applied. The necessary materials for the study were devices for automatic collection of traffic flow characteristics, such as video cameras and traffic detectors, Any Logic version 8.0 for modelling, and a package of descriptive statistics in MS Excel.

Results. In the course of the study and the experiment, a difference in the main characteristics of the traffic flow when using standard reduction factors and without using them, taking into account the dynamic and technical parameters of trucks was established. At the object of the study, the difference in the value of the average travel time () for various methods of accounting for trucks, observed in the range [-51.5%; 16.8%] and average speed () in the range [20%; 34%] was determined. As a result of mathematical research, functional relationships between the average speed and traffic intensity are determined, taking into account the presence of trucks of various categories, their technical and dynamic parameters. The ways of further research are determined.
Soot formation and effect on engine oils
Authors: Pashukevich S. V.
Published: July 2023

Introduction. During the combustion of diesel fuel in a diesel engine with an increased fuel supply, as a result of its incomplete combustion, soot particles are formed, which are either released into the atmosphere or inevitably enter the engine oil. Soot, polluting the engine oil, causes a change in its quality indicators. Soot is very small particles formed by a complex reaction mechanism in the flame of a fuel-rich region during the combustion of hydrocarbons in the absence of air, mainly consisting of a mixture of amorphous carbon and organic matter.

Materials and methods. This paper presents the results of a literary review aimed at studying the ways of soot occurrence during the operation of diesel engines, its effect. The mechanical properties of diesel soot are also discussed on the surfaces of friction pairs and engine components.

Conclusions. The soot content in engine oil will increase sharply in engines with exhaust gas recirculation, which leads to an increase in temperature in the friction zones and viscosity of the lubricant, as well as to the formation of deposits on hot parts. These processes occur due to the discharge in the crankcase space and the intensification of the intake of gases from the combustion chamber. Oil change intervals should be monitored at an increased rate of soot entering the engine oil.

Scope of the study / opportunity. This type of study will help determine the causes of soot in a diesel engine, understand the consequences of using engine oil contaminated with soot particles.

Originality / value. The conducted research can be the basis for the development of recommendations for improving the maintenance of internal combustion engines for enterprises that have cars with diesel engines at their disposal in order to increase the resource of power units and reduce operating costs.
Crying Havok and (Re)claiming Rights
Authors: Hedahl Marcus
Published: July 2023

In the last decade, there has been a seismic shift in debates about the ethics of war, a shift that challenges the foundational assumptions of the just war tradition. In the revisionist project responsible for this shift, the key question becomes whether an agent, through their actions, is liable to the use of deadly force. More recently, this revisionist project has been modestly expanded, from considering how killing others could make an agent liable to the use of defensive force to considering how saving or not saving others could do so as well. In this paper, I consider how analyzing questions of liability in this new, expanded domain can highlight important distinctions that we may miss when we consider the same kinds of actions (i.e., killings) time and time again in considerations of self-defense and war. Morally salient elements that would normally be concealed can be revealed, and we can use that insight to consider the paradigmatic case of killing anew. It turns out that a more nuanced understanding of rights – the moral element that is meant to the centerpiece of the revisionist project – can be used to demonstrate a serious limitation for both revisionism and the just war tradition it seeks to replace. One can hold onto one of core aims of the revisionist project, its weary skepticism of the blank pass given by traditional just war theorists to those who fight unjust ad bellum wars, while maintaining that a fuller appreciation of the moral complexities of rights often strengthens, rather than undermines, many of the traditional in bello rules.
Nonhuman Animals and Epistemic Injustice
Authors: Lopez Andrew
Published: July 2023

In this paper, I argue that nonhuman animals can be subject to epistemic injustice. I consider Miranda Fricker’s (2007) account of the nature of the harm of epistemic injustice and highlight that it requires that a knower be invested in being recognized as a knower. I argue that a focus on know-how, rather than testimony or concepts for self-understanding and communication, can serve to highlight how nonhuman animals can suffer epistemic injustice without an investment in recognition, by focusing on distributive justice concerning epistemic goods. Drawing from work in animal ethology and movement ecology, I argue that human interruption of animal lifeways has negative downstream effects on nonhuman animals’ ability to acquire ‘answers’ to ‘questions’ they have an interest in answering: namely, acquiring both true beliefs about conspecifics and their environment, as well as acquisition of behaviors and skills that enable everyday successful coping, and that these interruptions can constitute epistemic injustice.
Promises, Commitments, and the Nature of Obligation
Authors: Molina Crescente
Published: July 2023

Under a widespread understanding of the nature of moral obligation, one cannot be under an obligation to perform or omit an act and have a moral power to release oneself from one’s obligation. According to this view, being under an obligation necessarily entails relinquishing one’s sovereignty over the obligatory matter, that is, one’s capacity to control one’s own obligational world. This essay argues against such a view. I shall argue that by making what I will call a commitment, a person assumes an obligation towards another on a given matter whilst preserving the power to release herself from her obligation. Commitments constitute morally obligatory acts over which’s obligatoriness those obliged always retain control. They constitute obligations over which obligors preserve moral sovereignty. I show that the notion of commitment sheds light on the structure of important moral phenomena such as some of our loyalty obligations, and, furthermore, that it reveals something central about the justification and scope of the law of contracts.
On an Analytic Definition of Love
Authors: VanderWeele Tyler
Published: July 2023

The paper puts forward an analytic definition of “love” that is intended to characterize the use of the word in expressions of the form “He/she loves...” It is proposed that when “love” is used in such contexts, it denotes “a disposition towards either (i) desiring a perceived good or desiring union with it, either as an end itself or with it being a source of delight in itself or (ii) desiring good for a particular object for its own sake.” The first of these might be referred to as unitive love and the second as contributory love. A defense of the definition is offered by considering its application to a number of seemingly problematic cases. Many of the puzzling features of “love” arise from the disjunctive nature of its use – that we use “love” when either unitive or contributory love is present. Confusions arise when we take what can be said about unitive love, and apply this to contributory love, or vice versa, or when we assume all uses of “love” entail both unitive and contributory aspects. Consideration is given to the implications of the proposed definition and distinctions for cultivating love within society, marriages, political life, and media.

Historical Development of Frontier Stock Markets in Sub-Saharan Africa
Authors: Imhanzenobe Japhet Osazefua
Published: July 2023

Purpose: The purpose of this research is to review and compare the development of the three major frontier stock markets in Sub-Saharan Africa over time. The study provides some narrative around the historical development of each market as well as a theoretical backdrop for stock market development studies.
 
Theoretical framework: The adaptive market hypothesis was used as the theoretical backdrop for the study. The adaptive market suggests that stock markets develop in an evolutionary manner (similar to natural selection). This evolution of stock market development is influenced by changes in investors’ behavior and regulatory standards.
 
Design/methodology/approach: Data was collected from 1993 to 2020 on the IMF market efficiency score, the value of stocks traded, aggregate market capitalization, and the number of listed companies for the sample markets. The study used descriptive statistics and trend analysis to discuss and compare the stock market development indicators across the different selected frontier markets.
 
Findings: The study discovered an improvement in stock market performance across the sample period. The Johannesburg Stock Exchange was found to be the most developed of the three stock exchanges. The Nigerian Stock Exchange was second while the Nairobi Stock Exchange was third. Some factors that erode the performance of these stock markets were also discussed.
 
The practical and social implications: The sample stock markets are the major frontier markets, and so are often the first stop for foreign investors that want to penetrate the Sub-Saharan African markets. The performance of these markets often determines the level of foreign direct investment (FDI) and foreign portfolio investment (FPI) that flow into Africa.
 
Originality/ Value: Few studies have investigated the performance of stock markets in Sub-Saharan Africa. Also, the few studies that investigate the performance of these markets rarely proceed to discuss the market-wide factors that erode the performance of these markets compared to those of developed economies. Some factors like the size of the economy, low financial literacy, misplaced government policies, poor investment culture, buy-and-hold-tight attitude, and high transaction costs were identified and discussed.

What we can do to realise our excellence and equity goals in literacy
Authors: McNaughton Stuart
Published: July 2023

The research, practice and policy communities in Aotearoa New Zealand know a lot about literacy; the what and how of development, and what works for whom, under what conditions. But two issues stand in the way of better meeting the national excellence and equity goals. One is solving system challenges of variability, scalability, sustainability and capability. Solving this requires taking a life course approach to the evidence, including what optimises enjoyment and criticality from early learning through schooling; and guaranteeing collective clarity and accountability for effective practices. Solving the second, too much selective and limited reasoning about what is needed, requires better understanding our histories of practice and outcomes, and the evidence about these; taking seriously the collective need for evidence-based reasoning; better understanding the nature of the sciences involved; and careful and collective reasoning to understand what is robust evidence and what is inaccurate and misleading. Both issues have implications for capability building through resourcing, initial teacher education, and professional learning and development.
I Cannot Afford The Current Crisis; Let Alone Prepare For a Future One
Authors:   , Roundill Melanie
Published: July 2023

This research aims to understand the experiences of earthquake preparedness of low- income students who rent in Wellington City, Aotearoa New Zealand. Wellington City sits atop a number of earthquake fault lines, with it expected that a large-scale earthquake, that would impact Wellington City, has a 10-60% chance of occurring in the next decade. Concurrently, Wellington City's unstable housing market is raising the cost of living, significantly impacting low-income tertiary students. This puts many low-income students in a position where they cannot afford basic living needs, so they rent unhealthy and unsafe houses. As a result, students experience social exclusion because they are unable to fully participate in life-sustaining actions, such as disaster preparedness; therefore, are more likely to experience negative physical and psychological health and well-being implications. Eight photo elicitation semi-structured interviews were conducted with low-income students and analysed using narrative analysis techniques. The findings suggest that low-income students were unprepared for earthquakes due to power imbalances between renters and landlords, financial limitations, a lack of dwelling space, and being newly independent. Low-income students also lacked knowledge about renting rights and earthquake preparation. This research offers reasoning for why students need to be considered as an at-risk group in disaster preparedness, with the suggestion that future research continues to identify how to increase disaster preparedness for low-income students.

Mathematics is a scientific discipline, learning mathematics is a mandatory learning that is taught to students. However, not a few students stated that they did not like mathematics because they thought mathematics was difficult. In fact, learning mathematics actually brings many benefits and advantages that will be felt later when they grow up and live real life. It turns out that in reality learning mathematics in Indonesia still uses an approach that is less meaningful, rigid, and unattractive to students. In fact, we have to meet the demands of 21st Century learning. For this reason, researchers conducted research on ethnomathematics-based Hypothetical Learning Trajectory (HLT) RME through regional specialties, namely wingko tripe in the process of learning mathematics in class III SD. This research aims to make mathematics learning more meaningful, interesting, and not boring for students. This study uses the Design and Research method. This study proves that using the Hypothetical Learning Trajectory (HLT) can help students understand the learning trajectory to understand the material angles with the media in the form of concrete objects, namely wingko, can create more meaningful, interesting, and not boring mathematics learning.
