Cross-task consistency and variability in assessing number word knowledge
Authors: Cheung Pierina , Merkley Rebecca , Wege Theresa Elise , Jasim Sara , Ansari Daniel
Published: October 2024

The cardinal meanings of the first few number words are often assessed with the Give-N Task, and children’s knowledge of number words can be represented by “knower-level”, with N-knower representing children who have acquired cardinal knowledge of number words up to N. In the current study, we sought converging evidence for knower-levels by examining the correspondence of knower-level classifications between the Give-N Task and the Point-to-X Task. In Study 1, we tested 69 preschool-aged children and found that children at the higher knower-levels often did not receive the same classification across tasks. Further, children who were classified as having acquired the cardinal principle on the Give-N Task were more likely than subset-knowers to count on the Point-to-X Task, but they did not count very frequently. In Study 2, we conducted secondary data analysis on an existing study that included a Point-to-X Task with different stimuli and more trial types. We again found that children’s knower-level assessed with Give-N was not always associated with above chance performance for that number on the Point-To-X Task. These data suggest that knower-levels may adequately capture cardinal number knowledge for very small numbers but not for higher numbers. We discuss the practical implications of these findings and highlight a need for future studies to adopt a multi-method approach to establish a robust pattern of children’s number word acquisition.
The interplay between experimental heat pain and non-invasive stimulation of the medial prefrontal cortex on reinforcement learning with manipulated outcome controllability
Authors: Csifcsak Gabor , Babiker Samy Mohammed Engebø , Luzzi Federica , Mittner Matthias
Published: October 2024

Pain negatively affects several cognitive abilities, but knowledge about its effect on reinforcement learning (RL) is limited. During RL, instrumental choices can be influenced by heuristic tendencies to approach rewards or inhibit actions when facing potentially aversive events, introducing “Pavlovian bias” in behavior. Recent studies suggest that compromised outcome controllability enhances Pavlovian bias, a phenomenon that may be linked to suboptimal decision-making in learned helplessness (LH). Since LH is common in chronic pain syndromes, this study sought to establish a link between experimental heat pain (EHP), uncontrollable reward/loss and RL performance in healthy adults. In addition, we investigated if intermittent theta burst stimulation (iTBS) targeting the medial prefrontal/dorsal anterior cingulate cortex (mPFC/dACC) alleviates the deleterious effects of EHP on choice behavior. In a pre-registered, 2x2 between-group, double-blind study (N = 100), healthy adult participants underwent 3 blocks of an orthogonalized Go/NoGo task with two interleaved bouts of active or sham iTBS, and either EHP or warm skin stimulation combined with compromised outcome controllability during the task. Although EHP did not impact overall performance, it invigorated actions for rewards, reflecting enhanced Pavlovian bias. While two bouts of iTBS attenuated Pavlovian tendencies, this effect was counteracted by EHP, indicating antagonistic effects of pain and iTBS-modulated mPFC activity on Pavlovian-instrumental interactions. Surprisingly, EHP and iTBS exerted largely similar effects on other latent parameters of RL (go-bias, learning rate, exploration) in a manner that resembled LH. These findings shed light on the role of experimental pain and mPFC/dACC activity in LH-like choice behavior.

Published: October 2024

This research work is concerned with the comprehensive study of the electrical and optical characterization of an atmospheric pressure circular dielectric barrier discharge (APCDBD) in natural air. The effect of airflow and input voltage on the power supply’s behavior has been investigated to keep the electrode gap constant. The energy and power dissipated during the discharge cycle are calculated by the Lissajous plot and the time average of the voltage and current curve. For the optical characterization of APCDBD, light emission during the plasma discharge is examined electron excitation temperature, rotational temperature, vibrational temperature, and plasma density have been computed. The Boltzmann plot method is used to estimate the electron excitation temperature and vibrational temperature. The rotational and also vibrational temperatures are calculated from online MassiveOES software. It is found that multiple filamentry micro discharge is produced increasing the airflow and input voltage of the power supply. Energy per cycle of the discharge is increased for increasing input voltage and vice-versa in airflow. The discrepancy in the calculation of energy dissipation from discharge between time-averaged and Lissajous’s plot method is estimated. However, the fluctuation is less in the Lissajous plot method and hence, the calculation of energy from the Lissajous plot method is more suitable for plasma discharge. The power consumption of the plasma reactor is found to be dependent on the input of the power supply. Electron excitation temperature and the rotational temperature of the discharge decrease with increasing the airflow in the discharge and increase with increasing input voltage. Therefore, by using the airflow in dielectric barrier discharge, we can move closer to the room temperature of atmospheric pressure plasma.

Authors: Bhattarai Loknath
Published: October 2024

Diversity issue in the present context is a global issue of socialization. It has not yet been materialized into the education system in Nepal. The education system of a country should prepare students to function in today’s diverse society. There are issues emerging in the effectiveness of the diversity management and the concerns how to better shape the diverse classroom in Nepal. This paper focuses on issues such as teacher’s experiences in diverse classes, classroom management, and role of ICT integrated pedagogy to manage diverse classroom context. It also discusses the context, and experiences of teachers that can bring the diverse classroom situation into the right track. For this purpose, I apply narrative inquiry of two mathematics teachers (one male and one female) of University campus Kirtipur with more than ten years’ of teaching experience. In depth interview related to the experiences of teachers managing diverse in higher mathematics classes were conducted and found that there are different types of diversity in the context of Nepalese mathematics classroom viz. cognitive diversity and social diversity. However, the management of diversity is a great job for teachers, the use of ICT tools plays vital role in this direction. Although, teachers are little familiar to the diversity management skill they try to manage such type of diversity by supporting their students personally through ICT tools. Diversity works with social constructivist approach in educational field is trying to discuss in this paper. It also presents the role of ICT integrated pedagogy to manage the diverse classes by respecting student’s personal feelings.

Published: October 2024

This article focuses on citizens’ experiences of enablers of- and barriers to obtaining digital citizenship. E-applications for social assistance are used as an exemplar. In Sweden, as in many countries, there is political pressure on welfare services to become more digitalized, and to offer different kinds of self-service technology such as e-applications. Even if the goals of implementing these technologies are to increase efficiency and transparency and offer faster services to citizens, there is a risk of expanding the ‘digital divide’. and making it more difficult to obtain one’s digital citizenship and gain access to social rights. This article draws on a qualitative interview study. and explores citizens’ experiences using e-applications in two Swedish municipal social assistance agencies. Results show that most citizens had positive experiences applying for social assistance online, but there were some potential barriers. There were also differences in experiences in the two municipal social assistance agencies. We discuss how the increased digitalization of welfare services seems to push towards a blend of digital and social rights. In this process, social workers play an important role in countering new types of inequalities that emerge in evolving social assistance organizations. The article identifies several areas that merit further research.

Finding a “continuing city”: John Marrant’s Narrative Mapping as Geographical and Historical Imaginaries
Authors: Thomas Leah M.
Published: October 2024

John Marrant’s A Narrative of the Lord’s Wonderful Dealings with John Marrant, a Black (1785) draws on geographical and historical imaginaries between the Cherokee and the British in the southeastern US from the 1720s through the American Revolutionary War. Comparing eighteenth-century southeastern Indigenous and European colonial maps with Marrant’s narrative mapping reveals Marrant’s navigation of the same spaces and networks of relation that were coming under colonial management. As a “go-between,” Marrant negotiates Cherokee and other Indigenous nations’ relations, as well as furnishes a rare glimpse into Black and Indigenous relations. Marrant’s Narrative reconnects to a legacy of Cherokee and British negotiations in addition to Black loyalist networks. Through his narrative mapping, Marrant performs as a cartographer and mediator between the Cherokee and the British to forge a new path, a “continuing city,” to maintain his freedom.

Published: October 2024

This article explores the findings of a collaborative investigation of the Ballitore Collection, an archive of eighteenth- and nineteenth-century Irish Quaker materials that is held at the UCSB Library’s Special Research Collections in Santa Barbara, California. In this research project, students and faculty from three institutions—the University of California, Santa Barbara; California State University, Northridge; and Howard University—have used archival and computational methods to re-examine historical narratives of gender roles and secularization in eighteenth-century Quakerism. The project shows that computational methods applied to a medium-sized, manuscript archival collection can yield significant research findings that challenge traditional accounts of Enlightenment progress and secularization.
Family lawyers on cohabitation and judge-made law
Authors: Leckey Robert
Published: October 2024

This article advances debates on the limits of judge-made law to palliate legislative failure to respond to changing practice. Canadian judges have adjusted the general private law to address the situation of unmarried cohabitants. In Kerr v Baranow, the Supreme Court of Canada continued its adaptation of unjust enrichment to this end. The article reports on the first empirical inquiry into how the judgment is operating, including outside the courtroom. Interviews with family lawyers in Quebec show that bringing claims under the adapted doctrine is complex and costly. Variable and unpredictable outcomes impede fair and efficient private ordering. Cohabitation agreements do not seem a satisfactory solution. The study highlights shortcomings in the leading Canadian judgment, which recognizes some cohabiting couples as partnerships but stops short of presuming an equal sharing of gains during the union. But, since the participating lawyers pointed to factors that would reduce the efficacy of reform by judges or by legislatures, the study does not yield a broad preference for legislative reform over judicial reform.
ЕТНОПОЛІТИКА ТА НАЦІОНАЛЬНА СТІЙКІСТЬ В УМОВАХ ВІЙНИ
Authors: Волянюк Ольга , Ладний Юрій
Published: October 2024

Здійснено спробу пов’язати два актуальні концепти політичних наук – «етнополітика» та «національна стійкість», зокрема переосмислити їх сутність і тенденції змін в умовах війни. Підкреслюється, що виважена етнополітика могла би слугувати одним із інструментів збереження безпеки, єдності й сталості суспільства навіть в умовах збройної агресії. Стаття має за мету запропонувати сучасне розуміння проблем етнополітики як чинника національної стійкості та водночас історично обґрунтованої сфери життя суспільства. Поряд із тим з’ясувалось, що окреслені завдання неминуче актуалізують звернення й до інших сфер політики: політики пам’яті, політики ідентичності, політики у сфері свободи совісті, а також в освітній, інформаційній, культурній, соціальній, економічній та інших сферах життя суспільства.
Методологічною основою дослідження стали принципи об’єктивності, плюралізму, міждисциплінарності. Аналіз чинного нормативно-правового поля України дозволив осмислити дійсні й можливі державні стратегії етнополітики в умовах війни, водночас аналіз соціологічних опитувань – дослідити стійкість суспільства перед актуальними етнополітичними викликами, зокрема й збройною агресією. Кейс-стаді, акцент на сучасний досвід етнополітичних змін в Україні важливий і для виокремлення завдань порядку денного урядової політики, і для перспектив соціально-політичних досліджень етнічності загалом. Стверджується, що фактор етнічності важливо враховувати при розгортанні стратегій, програм і планів розвитку національної, соціальної, громадянської стійкості, а також стійкості демократії. Етнополітика трансформується навіть в умовах війни та свідчить про певний накопичений ресурс стійкості політичних еліт і суспільства загалом. Водночас етнополітика потребує подальших інституціоналізації, чітких безпекових заходів, міжінституційної співпраці, регіональних, національних і міжнародних зв’язків, сталої ресурсної підтримки та стійкого розвитку.
ПОВЕДІНКОВІ АСПЕКТИ УКРАЇНСЬКИХ СПОРТСМЕНІВ ПІД ЧАС ЗУСТРІЧІ НА СПОРТИВНИХ ЗМАГАННЯХ ІЗ РОСІЯНАМИ ТА БІЛОРУСАМИ
Authors: Коноваленко Євгеній
Published: October 2024

Повномасштабне вторгнення Росії в Україну викликало значні зміни в усіх аспектах суспільного життя нашої країни, зокрема у спортивній сфері, тому вивчення поведінки українських спортсменів під час спортивних змагань із росіянами та білорусами видається актуальним у контексті аналізу спортивних активностей. Незважаючи на значну кількість наукових публікацій із теми спорту загалом, спорту та маніпуляцій у контексті російсько-української війни, спорту як категорії політичного впливу, досі існує наукова прогалина у вивченні аспектів поведінки спортсмена, який представляє ту чи ту країну на світовій спортивній арені. Метою дослідження стало описати ключові поведінкові аспекти українських спортсменів під час зустрічі на спортивних змаганнях із росіянами та білорусами, зокрема проаналізувати поведінку вказаних суб’єктів на спортивній арені; виділити основні форми взаємозв’язку політики та спорту в матриці комунікацій.
На основі проаналізованих публікацій, відкритих даних у медіа вдалося зробити висновок про поведінкові аспекти українських спортсменів під час спортивних змагань з росіянами та білорусами, які визначаються індивідуальними та ситуаційними факторами та на які впливає складна взаємодія національної ідентичності, емоцій, спортивної майстерності, уваги медіа, міркувань безпеки. Незважаючи на ці труднощі, від спортсменів очікується збереження професіоналізму та зосередженість на своїй продуктивності в ігровому/змагальному просторі. Для аналізу поведінкових аспектів українських спортсменів на міжнародній арені у спарингу з білорусами та росіянами окреслено 8 критеріїв: пізнання, емоції, сила волі, увага, мотивація та ставлення, самооцінка, міжособистісні стосунки та розумова втома. Перспективою подальших досліджень є аналіз психології змагального спорту та його зв’язку із політичним дискурсом країни, яка перебуває у стані війни.
МОЖЛИВОСТІ ВПЛИВУ УКРАЇНСЬКОЇ ДІАСПОРИ НА ГРОМАДСЬКУ ДУМКУ ПІД ЧАС ВІЙНИ
Authors: Токарська Анастасія
Published: October 2024

Матеріал, представлений у статті, зосереджений на міжнародних відносинах, публічній дипломатії та діяльності української діаспори в умовах війни України з Росією. Основна мета дослідження – проаналізувати характер і можливості впливу української діаспори на громадську думку приймаючих країн під час військових дій, в контексті публічної дипломатії. Автором наголошується, що країнам для досягнення основних цілей у реалізації своїх національних інтересів, доступні сучасні інструменти публічної дипломатії, які допомагають: по-перше, подолати негативні образи свого минулого, по-друге, поширити свої цінності та модель і, по-третє, широко повідомити про свої порівняльні економічні та торговельні переваги для іноземних інвестицій. В умовах російської агресії проти України, четвертою і найголовнішою є необхідність згуртування закордонних українців для забезпечення належного впливу на громадськість своїх країн з метою забезпечення надання Україні політичної, військової, гуманітарної та іншої допомоги в цілях протидії зазначеній агресії.
Автор розглядає поняття публічної дипломатії, сутність її форм, деякі особливості співпраці з діаспорою. Увагу приділено ролі діаспори по просуванню позитивного іміджу України як держави в умовах військових дій. Українська діаспора показала, що може реально впливати на громадську думку практично в усіх країнах світу. В українській спільноті є чимало науковців, бізнесменів, юристів та маркетологів, які могли б допомогти сформулювати вагомі аргументи щодо того, чому Україна заслужила підтримку Заходу. Українська дипломатія повинна мати ці аргументи «під рукою», а діаспорі потрібно не просто впровадити, а чітко закріпити їх у суспільній свідомості приймаючих країн. Це не проста мета, для її реалізації необхідне, на думку автора, в першу чергу, чітке розуміння того, що таке діаспора у сучасному світі, як вона співпрацює в рамках системи публічної дипломатії України, які інструменти і методи впливу на громадську думку приймаючої країни їй доступні та як оцінити таку діяльність.

El carcinoma primario de la trompa de Falopio es poco frecuente entre las neoplasiasmalignas primarias del tracto genital. Representa aproximadamente el 1% de todaslas neoplasias malignas del aparato reproductor femenino y es más frecuente enlas mujeres menopáusicas. Una variante histológica muy poco frecuente que puedeafectar la trompa de Falopio es el carcinoma primario de células transicionales.Se parece al cáncer epitelial de ovario desde el punto de vista histológico y clínico.Sin embargo, las pacientes suelen presentar síntomas inespecíficos. El diagnósticopreoperatorio es difícil debido a la falta de elementos concretos para ello y a que raravez se le considera en el preoperatorio. Generalmente el diagnóstico suele basarseen los hallazgos histopatológicos. En comparación con el adenocarcinoma típico delas trompas de Falopio, es probable que este carcinoma no sea tan agresivo, tengauna mejor respuesta a la quimioterapia y un buen pronóstico en comparación con elcarcinoma epitelial de ovario. Es importante tener en cuenta los tumores primariosde las trompas de Falopio en el diagnóstico diferencial de las tumoraciones pélvicas.Se presenta un caso de carcinoma primario de células transicionales de la trompade Falopio.

Published: October 2024

Nowadays, numerous studies have proven that slag-alkaline systems: cements and concretes are promising materials that compete with ordinary cement concretes in the construction industry. This is justified by a wide list of their competitive properties that meet modern requirements for building materials and products. However, despite the positive aspects of this group of materials, they are characterized by significant drawbacks that limit their wider practical application, including shrinkage during hardening. Within the framework of the article, the influence of the gypsum-containing component – citrogypsum, on the character and kinetics of shrinkage deformations of slag cements of various component compositions during the hardening process was studied. It was found that, depending on the type of alkaline activator, the addition of citrogypsum had a different effect on the shrinkage values of the binding system. When the NaOH binding system is activated, the introduction of citrogypsum helps to reduce shrinkage deformations up to two times. When using Na2CO3 and Na2SiO3 salts as alkaline activators, the addition of citrogypsum contributes to a sharp increase in shrinkage from 5 to 10 times.

Background: The integration of Artificial Intelligence (AI) into daily life provides a unique opportunity to address significant health concerns. In particular, the tech-savvy adolescent population could benefit from AI-enhanced access to reproductive health services, especially for the prevention, screening, and treatment of Sexually Transmitted Infections (STIs). Objective: This research aims to evaluate the impact of AI technology on improving adolescents' access to reproductive health services related to STIs. The study involves a systematic review of literature published from 2020 to 2024 across various databases. Methods: A systematic review methodology was employed, utilizing databases such as Google Scholar, PubMed, Semantic Scholar, Science Direct, and IEEE-XPLORE. Keywords used in the search included "artificial intelligence," "adolescents OR teenagers," and "sexually transmitted infections OR sexually transmitted diseases." Results: The review identifies AI as a pivotal tool in sexual education, particularly through the use of interactive and engaging chatbots. AI facilitates innovative educational interventions, allowing vulnerable and marginalized groups, including adolescents, to discuss and learn about sensitive topics like STIs. Conclusion: The study highlights the significant potential of AI in improving sexual health education for adolescents. The limited availability of research in this area underscores the importance of this study in advancing knowledge and addressing gaps in the application of AI for adolescent STI prevention and treatment.
Noradrenaline Extravasation Management in the Absence of Phentolamine: A Case Series
Authors: Koh Hock Peng , Suen Teoh Paula Suen , Zainuddin Muhammad Khaire
Published: October 2024

Noradrenaline (norepinephrine) extravasation can lead to tissue ischemia due to its vasoconstrictive properties. Phentolamine is the preferred treatment but is often unavailable in many Malaysian healthcare facilities. Alternative treatments, such as topical glyceryl trinitrate (GTN) and terbutaline injections, have limited data supporting their use. This case series reports two instances of noradrenaline extravasation successfully managed with terbutaline injections and extemporaneously prepared topical GTN in an Emergency Department setting. These cases highlight the effectiveness of terbutaline and GTN as viable alternatives, providing valuable insights for emergency care in settings where phentolamine is not accessible.
Exploring Axillary Vein Central Cannulation in Critically Ill Trauma Patients: A Focus on Infraclavicular Techniques
Authors: Harvendhar Singh Gurjeet Singh a/l , Syed Azman Sharifah Sofia
Published: October 2024

Managing major trauma in hospital settings, especially in emergency departments, presents significant challenges. Hypovolemic shock, often resulting from hemorrhage, is commonly due to bleeding in non-compressible areas like the abdomen and thoracic cavities, complicating intravenous access. Central vein cannulation is typically performed for effective volume resuscitation and blood transfusions prior to surgery, with common sites including the internal jugular, subclavian, and femoral vessels. However, in acutely bleeding trauma patients, early pre-hospital interventions such as cervical collars and pelvic binders can impede the cannulation of these veins and limit access to traditional central venous sites. This article explores the cannulation of central axillary veins, an underutilized yet advantageous route. Central axillary veins are readily accessible and provide a viable alternative for resuscitation in major trauma patients in emergency settings, offering a practical solution when other central venous access points are compromised.

Authors: Borisov D. I. , Polyakov D. M.
Published: October 2024

We consider a non-self-adjoint Schrödinger operator on the unit segment with the Dirichlet condition perturbed by an operator of small translation. The main result is the three-terms asymptotics for the eigenvalues with respect to their index and this asymptotics is uniform in the small translation. We also show that the system of eigenfunctions and associated functions of the considered operators forms a Bari basis in the space of functions square integrable on the considered unit segment.

Published: October 2024

Nigeria has been facing a food crisis problem, with most of the poor population having limited access to adequate quantity and quality food. Food security reflects the stability of food supply, availability of, and access to food, and affects the amount of food consumed, which has implications for the population’s health. Thus, this study examined the socio-economic drivers of food security among smallholder rice farmers in Ebonyi State, Nigeria. Primary data was collected under the Feed the Future Innovation Lab for Fish (Integrated rice-fish farming system) funded by USAID through a three-stage sampling technique. Foster–Greer–Thorbecke (FGT) and the Endogenous Switching Regression model were applied in the data analysis. The mean per capita household food expenditure is N 2,456.42, and the food security line is N 1,026.43. The food security measure shows that 46.67 percent of the households experience the incidence of food insecurity, 24.6 percent point is the food insecurity depth, and 17.2 percent point is the severity of food insecurity. The ESR model shows that the drivers of food security are access to credit, marital status, farming experience, primary occupation, education, and farm size. The study proposed implementing more developmental programmes that focus on poverty alleviation, which should be gender inclusive with an option of credit support to the rice farmers.
On Problems of International Liquidity in Capitalist World Economy
Authors: Hrnčír Miroslav
Published: October 2024

In capitalist countries, there has been a very lively debate in recent years about the legitimacy or illegitimacy, adequacy or inadequacy of the current form of the international monetary system. One of the main indirect motives for this general attention now being given to international monetary problems is the unfavorable development and weakened position of the reserve currencies, i.e. the US dollar and the pound sterling. The dollar and the pound form, to a greater or lesser extent, part of the monetary reserves of all capitalist countries, and concern over their prospects necessarily leads to considerations of the possibilities and reliability of the entire current international monetary system.
The Role of Culture on Foreign Policy
Authors: Ort Alexandr
Published: October 2024

Recently, in the research of international relations and political science, increased attention has been paid to issues of culture. This is not because these fields of science "fashionably" focus in this direction, but it largely reflects the fact that many countries increased attention to the role of culture in creating their foreign policy line and in enforcing it.
Undoubtedly, it is related to the overall development of the international situation, where the policy of peaceful coexistence is increasingly being promoted against the influence of imperialist countries. If the influence of military and power factors in world politics weakens, the space for the action of other factors, especially culture, undoubtedly expands. The possibility of eliminating wars from international relations offers the perspective of peaceful coexistence, and here the exchange of cultural values ​​comes to the fore.

The construction of developing countries (in the next RZ), which J. Néhrú said is state of exploding poverty is well known. At all meetings of the UN and its organizations but also on various other occasions, the position of RZ is reminded and studied wind, thereby constantly new circumstances and connections emerge, which change they were not intended, or they were overlooked. It is now one of the main problemsof the world. According to the United Nations Development Program (The Second Imperative New York, date not given) industrially developed countries in which not even a third of the world's population lives, they have 86% of the world's gross product, which corresponded to 1097.4 billion dollars in 1964, while the RS, in which there are more than two thirds of humanity (and by the end of the century it should be ¾), have only 14% of the gross world product, or 178.6 billion dollars.)

From June 20 to July 2, 1966, the second World Conference on Land Reforms was held in Rome, jointly organized by the UN, FAO (United Nations Development and Agriculture Organization) and ILO (International Labor Organization). The conference was attended by more than 300 representatives from 70 UN member countries (only Bulgaria, Hungary and the Mongolian People's Republic were represented from the UN socialist member countries) and UN specialized and advisory institutions. The CSSR was represented by a three-member delegation (Ing. O. Klokonik from the National Economic Planning Research Institute, Assoc. H. Schimmerling from the Institute of Rural Sociology and History of Agriculture at the University of Prague, A. Tauber from UMPE, and Prof. J. Tauber from the University of Agriculture).
Military Technology, Character of War and Strategic Conceptions
Authors: Zvada Ján
Published: October 2024

I heard someone say in a random discussion that the term contemporary military a foreign political concept automatically evokes in him the idea of ​​a whole galaxy the names of well-known bourgeois theoreticians, but he does not remember the name of any Marxist thinker in this context. H. Kissinger, H. Kahn, R. Aron, W. Rostow, L. Hart, P. Gallois and others have no equal in this field in the socialist countries. The register of Marxist workers remains relatively thin and short. The main reason for this fact is well known and very simple. The science of political strategy stagnated for a long time in our country for various reasons. In capitalist states, within the framework of existing possibilities and conditions, it developed strongly, especially in terms of intensity and quantity. (We see that in France alone, almost 1,000 titles have been published in recent years on topics related to issues of war and peace and military policy.)
