Distribution and Conservation Status of the South-Caspian Subspecies of the Eastern Slow Worm, Anguis colchica orientalis (Squamata: Anguidae)
Authors: Kidov Artem A. , Petrovskiy Andrey B. , Ivanov Andrey A. , Litvinchuk Spartak N.
Published: August 2023

Anguis colchica orientalis is an endemic subspecies of the eastern slow worm that lives along the southern coast of the Caspian Sea. This reptile usually inhabits forests in the Talysh and Alborz mountains, Lenkoran and South-Caspian lowlands from –27 to 1890 m above the sea level (a. s. l.). The majority of localities (82%) are scattered across the coastal lowlands and low mountains. In order to study the distribution and estimate ecological preferences of the species, we applied maximum entropy modeling using 108 localities from Azerbaijan and Iran. The range of the subspecies covers mainly coastal lowlands, eastern slopes of the Talysh and northern slopes of the Alborz ridges. Of the parameters included in the model, slope, barren land and precipitation of driest month were the variables with the highest percentage contributions (29, 16, and 10%, respectively). The slow worm does not avoid human-transformed biotopes and is common in some localities. The main threat to Hyrcanian populations of the slow worm is degradation of suitable habitats, primarily a total deforestation.

Published: August 2023

A new species of rock lizards of the genus Darevskia Arribas, 1999 — Darevskia arribasi sp. nov. is described from vicinity of Ertso Lake in South Ossetia. In comparison of Darevskia arribasi sp. nov. with other species of the «saxicola-brauneri» complex [D. lindholmi (Szczerbak, 1962), D. saxicola (Eversmann, 1834), D. brauneri (Mehely, 1909) (including D. b. brauneri, D. b. myusserica Doronin, 2011, D. b. darevskyi (Szczerbak, 1962), and D. szczerbaki (Lukina, 1963)], the new species is characterized by the smallest body size among all representatives of this complex L♂♂ — 55 – 62 mm; ♀♀ — 58 – 63 mm. The number of scales around the middle of the body (Sq.) in D. arribasi sp. nov. (52 – 58, more often 54 – 56) also significantly less than for D. saxicola sensu lato in generally. Along the throat from ear to ear fold there are 36 – 42 scales, less than in D. saxicola sensu lato. Two large preanal shields present in front of the anal shield in half of the individuals examined; in a quarter of individuals on both sides of the small central preanal there are by one enlarged lateral preanal shield, in another quarter all preanal shields are of the same size. Central temporal (Massetericum) always developed; always six pair of mandibulars, three in contact; collar straight, extremely rarely slightly serrated; ribs on the caudal scales are expressed to some extent; rostral usually separated from frontonasal by nasal shields. The coloration of adult males is olive-lettuce, or olive-brown from above; adult females are grey-brown; juvenile coloration coffee-brown with the blue and black spots on the edge of the outer ventral shields at the middle of trunk. Taxonomical status of new species is well supported with result of analysis of the mitochondrial cytochrome b data.

Published: August 2023

The key actual task of improving the tools of scientific and technological policy is the focus of R&D on obtaining socially significant results, including the creation of in-demand innovative products and technologies. Its solution requires appropriate improvement of the system of financial support for science. The authors of the article consider the existence of a clearly structured relationship between the national goals set for the scientific field as a whole and specific tools for their achievement as a necessary condition for effective management of this sphere. The paper analyzes the key instruments of R&D financing from the point of view of approaches to ensuring their effectiveness. The necessity of linking the volume of funding with the achieved results is shown, and specific proposals to solving this problem are made, including those based on the assessment of the technology readiness level (TRL).
Monetary Poverty and Education in Russia
Authors:   Moscow, Russian Federation, Alekhin B. I.
Published: August 2023

Russian economic literature on poverty abounds with empirically unsupported assertions about the positive relationship between education and living standards. The purpose of this study is to find empirical evidence of this relationship using panel data for 82 regions of the Russian Federation for 2000–2021. We applied a dynamic OLS estimator to estimate a panel cointegrating equation and found strong negative and statistically significant dependence of indicators of absolute and relative monetary poverty on the highest level of education of the regional working-age population. We also performed the Dumitrescu-Hurlin pairwise causality test, which shows that higher education does not homogeneously cause more absolute monetary poverty, but more absolute monetary poverty does homogeneously cause better education as people try to avoid poverty by raising their educational level. The results of these econometric procedures suggest that the purpose of the study has been achieved.
Problems and Methods of Improving the Legal Regulation of Public Investment in Russia
Authors:   RANEPA, Moscow, Russian Federation, Zolotareva A. B.
Published: August 2023

The article describes the main conclusions of the research work aimed at identifying key problems of and ways to improve the legal regulation of public investment in Russia. This work was based on the analysis of legislation and practice of its application. The analysis leads to the conclusion that there are significant shortcomings in the current legislation on planning and implementation of public investment, which hinder their efficiency. Among such shortcomings, the author highlights contradictions on the issue of bodies authorized to make key investment decisions; duplication of the investment component of state programs and national (federal) projects; approval of budget allocations for projects that are not ready for implementation; unclear grounds for raising the price of construction contracts, as well as for centralizing the functions of planning and implementation of sectoral investments, reduction of requirements for justification of investment projects. To mitigate these shortcomings, the author suggests to ensure systematic planning of large investments as part of national and federal projects, excluding these costs from the state programs; as a general rule, to abandon the practice of approving decisions on the implementation of budget investments by individual acts of the government and financing projects without the necessary documentation; to organize a comparative assessment of the efficiency of centralized and sectoral customers in investment management according to legally defined criteria; to return to the use of some previously applied criteria for the efficiency of investment projects.

Introduction: Investment decisions by many private and institutional investors are made taking into account the information (current estimates, forecasts, trends) contained in various country ratings regularly published by leading international financial and regulatory organizations (IMF, IBRD, UN), which allows investors to assess the level of risk and return on investment in various projects in these countries. The article evaluates the Environmental Performance Index (EPI), the most common in international studies, from the point of view of its use as a comprehensive tool for comparative analysis and an indicator for assessing the success of achieving the goals of sustainable social and environmental development of Russian regions. Purpose: Analysis of the feasibility of using EPI and its individual elements as part of an integrated approach to assessing the effectiveness of social and environmental development of Russia and its regions. Results: The authors reviewed the transformation of the methodology for calculating EPI over the entire period of its compilation; analyzed the dynamics of indicators, directions and blocks that make up the Index; assessed their adequacy to the geographical and sectoral features of social and environmental development. Conclusions: An extremely high level of politicization of the Index and inconsistency of its calculation methodology with the real conditions of Russia’s economic development were revealed. The inexpediency of its use in the present conditions to assess the social and environmental development of Russian regions, to build a rating of their sustainable development, to develop criteria for evaluating the effectiveness of environmental programs and projects, including in the field of green and environmental investments, was proved.
ADRM1 is differentially expressed in central nervous system metastasis in human breast cancer.
Authors: Mamoor Shahan
Published: August 2023

Metastasis to the brain occurs in a significant fraction of patients with breast cancer (1-3). We mined published RNA-sequencing and microarray data (4, 5) to compare primary and metastatic tumor transcriptomes for the discovery of genes associated with brain metastasis in humans with metastatic breast cancer. We found that adhesion regulating molecule 1, encoded by ADRM1, was among the genes whose expression was most different in the brain metastases of patients with metastatic breast cancer as compared to primary tumors of the breast. ADRM1 mRNA was present at increased quantities in brain metastatic tissues as compared to primary tumors of the breast. Expression of ADRM1 in primary tumors was correlated with patient overall, distant metastasis-free and recurrence-free survival. Modulation of ADRM1 expression may be relevant to the biology by which tumor cells metastasize from the breast to the brain in humans with metastatic breast cancer.
Helping citizens to lobby themselves. Experimental evidence on the effects of citizen lobby engagement on internal efficacy and political support
Authors: Aizenberg Ellis , Werner Hannah , van Geldere Sharon
Published: August 2023

Ideally, interest groups form a link between citizens and politics. However, this link is often flawed in practice. Many citizens also feel that the average citizen is not heard and that special interests exert undue influence on policymaking. One proposal to address this problem is the stimulation of so-called citizen lobby: Ordinary citizens can use lobbying strategies to achieve influence on decision-makers. This can benefit both policymakers and citizens as it can empower citizens to make their voices heard and it can help policymakers to build perceived legitimacy among citizens that are dissatisfied with existing decision-making processes. Formal channels for citizen lobby often exist but remain underused. However, what happens when governments actively engage with citizen lobby? We conduct two survey experiments in the Netherlands (N=1,218) and show that engagement with citizen lobby has no systematic effect on internal political efficacy but has robust positive effects on political support.
On a conjecture for the algebraic transfer in generic families of internal degrees
Authors: Phúc Đặng Võ
Published: August 2023

The binary field will be symbolized as $\mathbb F_2$ in the customary manner, whilst the Steenrod algebra over this field shall be written as $\mathscr A.$ In this work, we study Singer's conjecture [Math. Z. \textbf{202} (1989), 493-523] for the algebraic transfers of ranks 5 and 6 in the generic families of internal degrees. As a result, Singer's conjecture for these algebraic transfers holds true in respective internal degrees. The Singer algebraic transfer stands as a valuable instrument for unraveling the intricate structure of the cohomology ${\rm Ext}_{\mathscr A}^{s,k} := {\rm Ext}_{\mathscr A}^{s}(\mathbb F_2, \Sigma^{k}\mathbb F_2)$ of $\mathscr A.$ Remarkably, we have shown that the indecomposable element $y\in {\rm Ext}_{\mathscr A}^{6,44}$ is not in the image of the sixth algebraic transfer. \textit{The results obtained are entirely new and hold significant importance in describing the fifth and sixth cohomology groups of the Steenrod algebra}.
Measuring Internalized Learning Dispositions using Finger Tracking: The Cognitive Survey
Authors: Woodford Benjamin S.
Published: August 2023

The study seeks to evaluate the internalized learning disposition of elementary and middle school students who completed a Cognitive Survey designed for this pilot. The Internalized Learning Disposition Cognitive Survey is introduced here as a model of a novel survey design administered in a Finger Tracking environment on tablet computers. The survey utilizes a two-option forced-choice paradigm and is analyzed through a difference-based methodology, with design cues taken from the well-known Implicit Association Test and Likert-type self-report instruments. Findings suggest that traditional survey data cleaning can be significantly improved with this model of survey administration. Independent of differences in agree/disagree responses, significant behavioral differences are identified using trajectory classification indices as a methodological justification leading to spatial and temporal evolution analysis. The spatio-temporal analysis was performed to compare behavioral valence between learning dispositions towards math and art. The findings indicate that behavioral markers provide evidence that participants differentiate meaning early in the response decision process before the school subject is revealed, and late in the process the Cognitive Survey method can differentiate statement endorsement accessibility between the Math and Art categories on Agree/Disagree binary survey items. Findings suggest that researchers should consider using Finger Tracking methods for psychometric assessment including the Cognitive Survey.
The Dark Sides of the Brain: A Systematic Review and Meta-Analysis of Functional Neuroimaging Studies on Aggression
Authors: Dugré Jules R , hopfer christian , Winters Drew E.
Published: August 2023

Background. Aggression is a worldwide issue that has significant consequences for both the victims and societies. However, aggression is an umbrella terms with subcomponents such as motivation (i.e., Reactive versus Proactive) and forms (i.e., Physical versus Verbal) which aggressive behaviors may occur. Yet, brain circuits differentiating these subcomponents remains largely unknown.Method. A systematic search strategy was conducted up to May 1st 2023, using PubMed, Google Scholar, and Web of Science, to identify relevant studies. Coordinate-based meta-analysis was conducted on General Aggression, Reactive Aggression, Proactive Aggression, Physical Aggression and Verbal Aggression using spatial convergence (ALE) and effect-size (SDM-PSI) approaches.Results. Sixty-seven studies met the inclusion criteria. Meta-analysis revealed similar yet distinct neural correlates for General Aggression (i.e., Amygdala, Precuneus, Intraparietal Sulcus, Angular and Middle Temporal Gyri), Reactive Aggression (i.e., Amygdala, Periaqueductal Grey, Posterior Insula, & Central Opercular Cortex), Proactive Aggression (i.e., Septal Area, & Amygdala), Physical Aggression (i.e., Dorsal Premotor Cortex, Dorsal Caudate, & Dorsal Anterior Cingulate Cortex), and Verbal (i.e., Dorsal Anterior Cingulate Cortex). Exploratory analyses revealed the importance of affective, cognitive and social cognition processes as well as serotoninergic, dopaminergic, and cholinergic systems in the neural underpinnings of aggressive behaviors.Conclusion. Our findings highlight the importance of examining the subcomponents of aggression (i.e., motivation and forms) within a transdiagnostic framework. Hence, characterizing the neurobiological substrates of aggression may expand our search for targeted neuromodulation and pharmacological treatments.
Affiliation: A Consequential, Interstitial Trait
Authors: Blain Scott D. , Weisberg Yanna J , Condon David M , DeYoung Colin G.
Published: August 2023

Although development and maintenance of relationships is an essential part of mental health and well-being and nearly universal among humans, people vary in their tendency to affiliate with others. Affiliation represents an interstitial personality trait falling between the Compassion aspect of Agreeableness and the Enthusiasm aspect of Extraversion. Though interpersonal behavior has been studied extensively, the field lacks validated questionnaires measuring individual differences in Affiliation. Here, we document the construction and validation of a new Trait Affiliation Scale. Data were taken from six samples (ntotal = 27,198). Study 1 focuses on scale creation, including identification of 24 candidate items and initial tests of convergent validity. Study 2 focuses on scale refinement including the application of item response theory to create a ten-item scale. Study 3 investigates reliability and construct validity. Study 4 provides evidence of test-retest reliability in a four-wave longitudinal dataset. Finally, Study 5 provides evidence for criterion and incremental validity, testing associations of affiliation with outcome variables (e.g., social behaviors, social network size, social cognition, and affiliative states) above and beyond Agreeableness, Extraversion, and their aspects. We discuss the importance of affiliation as a trait and provide recommendations for future research using this new scale.
Expectation modifies the representational fidelity of complex visual objects
Authors: Moore Margaret Jane , Robinson Amanda K , Mattingley Jason
Published: August 2023

Prediction has been shown to play a fundamental role in facilitating efficient perception of simple visual features such as orientation and motion, but it remains unclear whether expectations modulate neural representations of more complex stimuli. Here, we addressed this issue by characterising patterns of brain activity evoked by two-dimensional images of familiar, real-world objects which were either expected or unexpected based on a preceding cue. Participants (n=30) viewed stimuli in rapid serial visual presentation (RSVP) streams which contained both high-fidelity and degraded (diffeomorphically warped) object images. Multivariate pattern analyses of electroencephalography (EEG) data were used to quantify and compare the degree of information represented in neural activity when stimuli were random (unpredictable), expected, or unexpected. Degraded images elicited significantly reduced representational fidelity relative to high-fidelity images. However, degraded images were represented with improved fidelity when they were presented in expected relative to random sequence positions; and stimuli in unexpected sequence positions yielded reduced representational fidelity relative to random presentations. Most notably, neural responses to unexpected stimuli contained information pertaining to the expected (but not presented) stimulus. Debriefing at the conclusion of the experiment revealed that participants were not aware of the relationship between cue and target stimuli within the RSVP streams, suggesting that the differences in stimulus decoding between conditions arose in the absence of explicit predictive knowledge. Our findings extend fundamental understanding of how the brain detects and employs predictive relationships to modulate high-level visual perception.
Person-Centered Modeling: Techniques for Studying Associations Between People Rather Than Variables
Authors: Woo Sang Eun , Hofmans Joeri , Wille Bart , Tay Louis
Published: August 2023

The goal of person-centered methods is to identify subpopulations of individuals based on within-group similarity of data relative to between-group variability. In this paper, we provide an overview of specific person-centered methods, thus shifting the attention from studying relations between variables to studying relations between people or entities of interest. Next, we present a selective and critical review of recent research utilizing person-centered modeling approaches, highlighting key trends in organizational psychology and organizational behavior literature from both the methodological and the conceptual perspectives. Lastly, we conclude with reflections and recommendations, highlighting several areas needing careful consideration when conducting person-centered research.
Investigating Preservice Teachers’ Attitudes Toward Lesbian, Gay, and Bisexual Students in Luxembourg
Authors: Galano Dario , Grund Axel , Emslander Valentin
Published: August 2023

Lesbian, gay, and bisexual (LGB) students face victimization in multiple contexts, including the educational context. Here, teachers can serve as an important resource for LGB students. However, teachers who are prejudiced against students from sexual minorities might not be able to fulfill this role. Accordingly, it is important to find out more about teachers' attitudes and their correlates, as such information can provide starting points for sensitization interventions in teacher education programs, which have the potential to improve the situation of LGB students in the school setting. In the present preregistered questionnaire study, we investigated the attitudes of 138 preservice teachers from the University of Luxembourg toward LGB students and tried to identify predictors of teachers’ attitudes. Results suggested that Luxembourgish preservice teachers hold mostly positive attitudes toward LGB students. Using correlation and multiple regression analyses, we identified the frequency of participants’ contact with LGB people in family or friend networks, hypergendering tendencies, sexual orientation, and religiosity as reliable predictors of attitudes toward LGB students. Age, gender, and right-wing conservatism did not reliably predict preservice teachers’ attitudes in the regression models. Our findings thus offer support for intergroup contact theory and have implications for teacher education in Luxembourg.
Effects of Trash Talk on High School Athletes
Authors: Lannes Hiram
Published: August 2023

Trash talk is a captivating, complex part of sports that is often overlooked. The purposeof this paper was to explore how trash talk affects high school athletes. 63 male and female highschool athletes completed a survey containing both quantitative and qualitative questionsexamining how often they trash talked, how often they were the target of trash talk, how large ofa role their peers played in teaching them how to trash talk, how often trash talk affected them ina negative way, how early they started using trash talk, and their purpose for using trash talk.Results revealed that high school athletes trash talk often, and they use it with a specific purpose(hinder their opponent’s performance/improve their own performance). They start using it froman early age (pre-adolescence), and they learn it primarily thanks to their teammates, parents,coaches, and professionals. Furthermore, trash talk experiences differ between gender, age, andsport played. Males, older athletes, and contact sport athletes have more experience trash talkingthan females, younger athletes, and non-contact sport athletes, respectively. Trash talk affectshigh school athletes in a negative way both on and off the field. Thus, trash talk has reached alevel of normative acceptance and has both immediate and long-lasting negative effects on highschool athletes, and it may harm their mental health. Competition in sport is now more thanmerely physical; trash talk enhances the mental component of sports beyond what it is thus far

Practices of Gender-Responsive Budgeting in Nepal
Authors: Koirala Padma
Published: August 2023

This paper attempts to analyze gender-responsive budgeting (GRB) practices in Nepal. Gender-responsive budgeting (GRB) is an approach to budgeting that uses an interrelated gender lens to respond to the diverse experiences of gender-diverse groups. This budgeting is also known as gender budgeting. This paper is based on descriptive research design and mixed research methods as well as secondary. Secondary data were collected from the reviews of Gender Responsive Budgeting reports and articles. Both archives and digital sources were used to search review materials. The findings of this paper show that GRB is a fiscal policy or administration that is used for promoting gender equality for girls and women. It provides a tangible framework for mobilizing budgets through a wide range of actors to address the gender-diﬀerentiated gaps to achieve desirable gender equality outcomes. Indeed, GRB can enter any stage of the budget cycle by identifying the prominent efforts. This paper concludes that gender issues became at the center of inclusive development since ancient times in Nepal. The fiscal policy tries to address GRB from2007/08 with progressive efforts, although the implementation of GRB faces a lot of challenges and barriers to achieving desirable outcomes. Despite this, the international community has recognized the effort of Nepal as a prominent GRB process.
An Activity Theoretical Perspective on Writing and Supervising a Master’s Thesis
Authors: Bastola Madhu Neupane
Published: August 2023

For students as novice researchers, a master’s thesis is the most demanding component because it requires them to display and learn research skills and work independently. Unfortunately, master thesis supervision has remained far from the limelight of university pedagogy. Drawing on mixed-methods research, this paper characterizes the writing and supervising of a master’s thesis from the perspective of cultural-historical activity theory. It presents various components of the activity system and how the interaction between these systems creates conflicts and contradictions. The implications of such an understanding to effective master’s thesis writing and supervision have been provided.

Suggestions on extended producer responsibility mechanism in Vietnam from international experiences
Authors:   Ministry of Natural Resources and Environment, 10 Ton That Thuyet, My Dinh Ward, Nam Tu Liem District, Hanoi, Vietnam, Nguyen Minh Khoa
Published: August 2023

Extended producer responsibility (EPR) serves as a policy instrument, ensuring that manufacturers and importers of specific products bear responsibility for their collection, recycling, and disposal once consumed, thereby alleviating the public financial burden of waste management whilst enhancing recycling rates. Registration, an integral component of EPR systems, denotes the identification of obliged manufacturers and importers, and the accumulation of sales data for products subject to EPR. The principal functions of the registry encompass: delineating manufacturers and importers with EPR obligations; reporting aggregated data; and overseeing the adherence of manufacturers and importers in executing their extended responsibilities. This paper encapsulates the experiences of several countries with respect to the organisation and administration of registration agencies for manufacturers and importers of packaging, proffering potential recommendations for Vietnam.
Digital literacy of Vietnamese human resources

Published: August 2023

The comprehensive digital transformation taking place across all aspects of global and Vietnamese societal life is both objective and inevitable. The successful execution of this transformation necessitates the development of appropriate digital human resources. Digital literacy has emerged as a paramount competence of the 21st century. Despite the qualifications and skills of Vietnam’s human resources, digital literacy remains limited. The demand for digital literacy is substantial and represents an urgent requirement for Vietnam in its pursuit of establishing a digital government, society, and economy. This paper explores facets of digital literacy, analyses the current state of digital literacy amongst Vietnamese human resources, and, based on this analysis, proposes recommendations and solutions to advance the digital literacy of Vietnamese workers.
Rubber industry in Southern Vietnam (1954-1975): An economic dimension
Authors:   Institute of International Relations, Ho Chi Minh Academy of Politics, 135 Nguyen Phong Sac Street, Cau Giay District, Hanoi, Vietnam, Dung Tran Ngoc
Published: August 2023

This paper examines the significance of the Statistical Yearbook of Saigon’s government in providing a comprehensive overview of the rubber industry in Southern Vietnam in the period 1954 to 1975. Prior to 1945, rubber plantations played a crucial role in the economy of French Indochina. After the French left Vietnam following the Geneva Agreement in 1954, the Saigon government endeavoured to take control of the rubber industry. However, due to the war and the incompetence of Southern Vietnam’s officials, the rubber industry in the region experienced instability during the period 1954 to 1975. Consequently, the Saigon government struggled to control and develop economic activities. This paper contends that despite these challenges, the rubber industry remained pivotal in Saigon’s economy after 1954. This claim is supported by the expansion of rubber plantations, the industry’s contribution to Southern Vietnam’s exports, and its impact on the overall economy and society.
Current View of the Spectrum of Pachychoroid Diseases. A Review
Authors: Stěpanov Alexandr
Published: August 2023

Introduction: The term "pachychoroid" (greek pachy- [παχύ] - thick) was first used by Warrow et al. in 2013. It is defined as an abnormal and permanent increase in choroidal thickness ≥ 300 μm, which is caused by dilatation of the choroidal vessels of the Haller's layer, thinning of the Sattler's layer and the choriocapillaris layer.
Methodology: Literary research focused on the current view of pachychoroid spectrum diseases, including clarification of the pathophysiological theories of the formation of "pachychoroid".
Results: It is assumed that “pachychoroid” disease has an autosomal dominant type of heredity. Depending on the further activity of various exogenous and/or endogenous factors, pachychoroid diseases may appear. According to the current knowledge, the spectrum of pachychoroid disease covers six clinical entities: pachychoroid pigment epitheliopathy, central serous chorioretinopathy, pachychoroid neovasculopathy, polypoid choroidal vasculopathy, focal choroidal excavation and peripapillary pachychoroid syndrome. In this study, we describe the clinical symptoms and objective findings of focal choroidal excavation and peripapillary pachychoroid syndrome. The current pathophysiological theory of pachychoroid diseases is based on impaired venous outflow from the choroid ("venous overload choroidopathy") and thickening of the sclera in the eyes of affected patients.
Conclusion: Pachychoroid diseases should be included in the differential diagnosis of characteristic features observed during multimodal imaging analysis of choroidal changes.
Racial Capital, Public Debt, and the Appropriation of Epekwitk, 1853–1873
Authors: Tozer Angela
Published: August 2023

This article argues that public debt financing facilitated the appropriation of the territories of Indigenous nations in the British settler colonies and does so through a detailed examination of Prince Edward Island’s public debt. The island’s government used public debt financing as a technique to direct capital into the colony, but to receive loans, the colonial government first needed credit. Settler-colonial credit derived from colonial governments’ claiming the territories of Indigenous nations as government assets. This history highlights the deeply racial characteristics embedded in the expansion of global public debt financing that characterized finance capitalism beginning in the 1820s. In this way, the unique history of the island and its “land question” can be placed into the broader global context of debt markets and processes of racial capital. Specifically, the 1853 Land Purchase Act used public borrowing to purchase lands from British landowners so that the island’s government could hold the land title. British landowners had their ownership rights secured despite the eighteenth-century Peace and Friendship Treaties that guaranteed the Mi’kmaq nation rights to their territory, which included Epekwitk, what the British named Prince Edward Island.

Más de treinta años pasó, para conocer hoy día, el potencial mineral del Oriente Boliviano, dónde en estas tierras de llanuras y selvas tropicales, existieron amplia vegetación y fauna abundante, que, en la actualidad con el avance de las fronteras agrícola, ganadera y minería, mucho ha cambiado. Regiones donde vivían, jaguares cazando venados y ñandús buscando hierba, granos y frutos naturales, ahora son áreas verdes de plantíos industriales, ganado vacuno y pocas áreas mineras poco contaminadas. Mineros aventureros por encontrar oro y mantener ilusiones de riqueza, obligaron a incursionar en selvas y regiones de los animales silvestres desde el 1540, con la llegada de los jesuitas al continente Sudamericano, los cuáles ingresaron al Oriente Boliviano por el Río Paraguay. Desde Alcides d´Orgbigny un naturalista francés, hasta Litherland un geocientista inglés, muchas generaciones pasaron y modificaron costumbres y hábitos de labrar la tierra y obtener minerales en estas tierras. El Oriente Boliviano, desde 1985, se ha convertido y ha destapado los ojos del país y el mundo, por sus riquezas naturales y variedad única de minerales, aún todavía con selvas y suelos fértiles. Hoy en día, sabemos que esta hermosa región de naturaleza propia, guarda en sus entrañas tesoros de minerales de índole extraordinario. El geólogo naturalista y grande explorador boliviano, Don Salomón Rivas ya en la eternidad, ya lo dijo, estará feliz, de que el Oriente Boliviano, se convirtió hoy en día, en la segunda región minera del país, con sus grandes riquezas minerales, que sostendrán el país, que algún día lo fue soñado. Los depósitos minerales del Precámbrico Boliviano, es un resumen expandido de la riqueza mineral, en esta vasta región de Bolivia, la tercera parte del territorio, con una inmensa variedad de minerales estratégicos y económicos para el desarrollo del país. Este resumen trata de explicar y mostrar, la cantidad de regiones, con estilos propios de mineralización y metalogénia, que merece ser explorada, investigada y desarrollada por las instituciones de desarrollo minero y exploración del país, con la inversión de capital de las empresas mineras, para su industrialización y desarrollo de estas regiones del país.

Виконано аналіз сучасних закордонних і вітчизняних досліджень і публікацій, щодо причин утворення основних типів несуцільностей та ушкоджень у конструктивних шарах найбільш розповсюджених в Україні промислових димових труб, дистанційного діагностування їх технічного стану шляхом розробки теоретичних розрахункових моделей температурних полів та моделей температурних полів штучних несуцільностей у структурі димової труби та пасивного тепловізійного методу з застосуванням сучасних тепловізорів. На основі аналізу сутності процесу теплопередачі в тепловому неруйнівному контролі промислових об‘єктів показано, що основним інформаційним параметром для пасивного тепловізійного методу є локальна різниця температур між дефектною та бездефектною зонами на поверхні контрольованого об‘єкта.
Подано результати досліджень механізмів теплопередачі, визначено густини теплового потоку крізь одношарову однорідну та тришарову різнорідну стінки димової труби й отримано повні термічні опори теплопровідності конструктивних шарів наведених циліндричних стінок труби. Обгрунтовано механізм визначення початкової температури на зовнішній поверхні димової труби в будь-якій її точці при введенні в експлуатацію та досягнення нею стандартного режиму для заданої температури димових газів. Наведено приклади виникнення несуцільностей в одному й у всіх конструктивних шарах тришарової структури димової труби (принцип «дефект над дефектом») і механізм утворення аномалій на зовнішній поверхні димової труби у вигляді гістограм температурного поля.
Розглянуто принцип реалізації способу термографування зовнішньої поверхні димової труби дистанційним пасивним тепловізійним методом і визначення за розмірами та формами гістограм аномалій температурного поля геометричних параметрів несуцільностей труби при діагностуванні її технічного стану.

Одним зі шляхів вирішення проблеми ефективного використання енергоресурсів у сучасних умовах є зменшення витрат газу в процесі його транспортування; повна утилізація тепла на компресорних станціях магістральних газопроводів.  Для ГТС характерні багаторівневість мережевої структури, значні розміри та часи релаксації збурень, розподілені та дискретні керуючі впливи, високий ступінь невизначеності як внутрішніх параметрів, так і зовнішніх чинників. ГТС обмінюється з довкіллям масою, імпульсом і енергією. Окремі складові ГТС взаємодіють між собою, а тому зміна режиму роботи окремої ділянки веде до зміни режиму всієї системи. Розрахунок параметрів функціонування таких систем є складною математичною проблемою. Її розв’язання вимагає побудови адекватних математичних моделей окремих об’єктів ГТС і розробки відповідних алгоритмів для забезпечення необхідної точності обчислень параметрів схеми з’єднань газоперекачувальних агрегатів (ГПА). Загалом, для встановлення робочих параметрів ГПА проводять розрахунок: режимноенергетичних параметрів (тиск і температуру газу на виході ГПА, а також затрати паливного газу); параметрів газового потоку на виході нагнітача; області допустимих змін параметрів ГПА; продуктивності нагнітачів і частоти обертів, за яких забезпечується перекачування газового потоку із заданими режимними параметрами; параметрів технічного стану нагнітачів і їх приводів згідно заміряних даних .У даній статті для розрахунку вибрано такий параметр як надійність. Основну увагу зосереджено на умові, пов’язаній  з оцінкою ефективності роботи КС. Визначено коефіцієнт готовності: з одного боку, з чисто імовірних і технічних позицій, з іншого – позицій показника ефективності роботи об’єкту, ґрунтуючись на усереднених величинах. Наведено необхідні розрахункові співвідношення для визначення коефіцієнта продуктивності, ймовірності станів і інших допоміжних величин для ряду технологічних схем, представлених у статті. Проведено висновки результатів реалізації математичної моделі засобами блочного програмування, доведено адекватність моделі. Продемонстровано один зі способів застосування моделі для вибору оптимального типу з’єднання ГПА при проектуванні нових КС.
