In the last decades, research in science mapping has delivered several powerful techniques, based on citation or textual analysis, for charting the intellectual organization of research fields. To map the social network underlying science and scholarship, by contrast, science mapping has mainly relied on one method, co-authorship analysis. This method, however, suffers from well-known limitations related to the practice of authorship. Moreover, it does not perform well on those fields where multi-authored publications are rare. In this study, a new method (...) for mapping the social structure of research fields is advanced, based on the analysis of the acknowledgments of academic publications. We first discuss the standard account of the function of acknowledgments in scholarly communication, then we introduce a new interpretative framework in which the acknowledgments are intended as positioning signals exchanged by researchers. Next, we provide the formal definition of the four acknowledgments-based networks that stand at the core of the method, and we test it on a humanities field, analytic philosophy. Results show that acknowledgement-based networks allow to reconstruct the fine-grained social structure of analytic philosophy from different perspectives. Furthermore, by comparing the citation-based maps of the field with the acknowledgments-based networks, it permits to shed light on the relationship between the intellectual and social layer of analytic philosophy. We conclude by presenting practical limitations of the method and by sketching some further research lines. (shrink)

In many films, story is presented in an order different from chronological. Deviations from the chronological order in a narrative are called anachronies. Narratological theory and the evidence from psychological experiments indicate that anachronies allow stories to be more interesting, as the non-chronological order evokes curiosity in viewers. In this paper we investigate the historical dynamics in the use of anachronies in film. Particularly, we follow the cultural attraction theory that suggests that, given certain conditions, cultural evolution should conform to (...) our cognitive preferences. We study this on a corpus of 80 most popular mystery films released in 1970–2009. We observe that anachronies have become used more frequently, and in a greater proportion of films. We also find that films that made substantial use of anachronies, on average, distributed the anachronies evenly along film length, while the films that made little use of anachronies placed them near the beginning and end. We argue that this can reflect a functional difference between these two types of using anachronies. The paper adds further support to the argument that popular culture may be influenced to a significant degree by our cognitive biases. (shrink)

The Crimea Conference is by all means an extremely complex historical event. Any attempt to estimate its role and significance without analyzing its ethical components would unavoidably result in unduly simplifying the historical reality of the time, as well as in forming erroneous assumptions that would necessarily be used in the analysis of the causes of Cold War. A thorough examination will show that as far as the ‘ethical’ issues are concerned, there are significant developments with regard to general methodology, (...) as well as its application to the sources. Generations of historians who have addressed the issue of Yalta Conference, although they have not been able to form a scientific, distinct ‘ethical’ tradition so far, have developed all the necessary prerequisites for its establishment. This is evident in the possibility of segmenting the issue in two parts on the one hand, and on the other in the availability of sufficient sources, structured databases, and selected outstanding works. Still, there are no studies about the Yalta Conference so far that address exclusively ethical issues concerning ‘good’ and ‘evil,’ ‘morality,’ ‘duty,’ and ‘honor.’ Although historiographical approaches are to a large extent dependent upon ethical viewpoints, in the case of Yalta agreements so far there have been no techniques available, so as to connect historical accounts with ideology, and historical facts with their philosophical background. In a sense, the situation is quite the same as it is with the study of prehistory: although there is an abundance of data and facts that can be primarily processed, there are no methodological guidelines, nor any devices to classify and explain them. This is also typical for any question raised about the ethics of the Yalta agreements in February 1945. (shrink)

Introduction. The article examines the dynamics of electoral competition over four electoral cycles from 2005 to 2019 as exemplified by forming representative bodies of local self-government in the city of Chelyabinsk. Particular attention is paid to the impact that the transition of Chelyabinsk to a twotier model of forming local self-government bodies in 2014 had on the electoral competition. The purpose of the paper is to study the dynamics of electoral competition in municipal elections in Chelyabinsk before and after the (...) 2014 reform. Methods. The empirical basis of the study is the database “Electoral competition in the elections of municipal deputies of Chelyabinsk (2005—2019)”, which includes 414 observation units. The analysis of the empirical material is carried out according to the method of G.V. Golosov’s triangle of relative sizes, proposed for classifying party systems and adapted for analyzing elections in single-mandate constituencies. Scientific novelty. The author suggests a methodology for analyzing electoral competition in singlemandate constituencies. For the first time, the phenomenon of “controlled competition” is analyzed on the basis of 4 municipal elections cycles. Results. The analysis makes it possible to speak about fluctuations in electoral competition, its decline in 2009 and 2014 compared to the 2005 elections and increasing by the 2019 elections Conclusions. The “controlled competition” was formed in Chelyabinsk in the period preceding the reform of 2014. The reform introduced a level of local self-government, the effectiveness and necessity of which is not obvious with the existing design of the electoral system. In the course of the reform, the principal-agent model of relations between local self-government bodies and state authorities was finally consolidated. The reform contributed to conserving the “controlled competition”. (shrink)

Modern Ukraine is a post-colonial, post-totalitarian state in which decolonization, decommunization, and de-Russification have not yet been fully implemented. This article sets itself the goal of reviewing the agenda of the processes of civilizational transit of Ukraine and developing theoretically grounded vectors of the said process. The important fact that the current stage of development of the “worldview gravity” of Ukrainian society is characterized by an eclectic system of stereotypes is also of significant importance: here coexist both old stereotypes of (...) consciousness and behavior, which have largely ceased to fulfill their functions, and new ones that are unstable and ambiguous. The series of ideas regarding the Ukrainian civilizational choice was already discovered in a monograph, “Civilizational crossroads of modern society,” and presented for Ukrainian readers a few years ago. The current article offers a revision of the previously presented ideas for the international audience of the journal readers, taking into account the current Ukrainian sociocultural situation, at the center of which are the challenges produced by the military aggression of the Russian Federation against Ukraine. The policy of new realism can become an effective tool for social modernization. The given word combination is not accidental: the realism of this type of politics insists on the need for the adequate perception of reality in all its essential aspects, and the novelty emphasizes the need to operate not with the laws and features of the socio-political status quo “in general,” but taking into account the latest dynamics, trends, threats, and problematic challenges. The people and the country need not only (and sometimes not so much) a thorough understanding of their cultural-civilizational, geopolitical, and economic-economic prospects but an indomitable character that guarantees the realization of their potential in spite of anything and against anything. On the difficult path of establishing a civilizational choice, Ukrainians will need not only the awareness of the incomplete state of political modernization, the limited, post-totalitarian (post-colonial, etc.) status, but also to work at the individual level to accelerate evolutionary processes. These processes can catalyze political decisions, not at the declarative level but at the practical level, to fill the steps for the approval of the civilizational choice with content. Step-by-step changes in favor of a new worldview horizon will require significant changes at the personal level through the rejection of destructive post-colonial (post-totalitarian, etc.) narratives in social practice in favor of the development of Ukrainian national identity, which will be preceded by the rational assimilation of the perspectives of civilizational choice, which is a fruitful combination of the European civilizational project and heritage of Ukrainian culture.

Publication date: 2 May 2019 Source: Author: Oleg Tarnopolsky The article discusses an innovative course taught to students majoring in English at Ukrainian universities. The course called “Specific Features of the English Language and English-Speaking Nations’ Cultures in the Context of International Communication” was designed to eliminate the lack of a number of issues that must be included in the curriculum of English language and culture studies to be learned by such students but which are ordinarily not included there (...) because each of them cannot make the subject matter of a separate university course and does not fit into the traditionally taught courses. The issues in question embrace: the specific role of English among other languages of international communication; World Englishes, International English and English as a lingua franca and how to choose the variety of English to be taught as a foreign language; the specifics of business negotiations in English in intercultural contexts, business presentations in English, and business telephoning in English in such contexts; communicative behavioral etiquette in intercultural communication in English; lifestyle communicative behavioral patterns of the English-speaking nations. The paper shows how teaching these issues enriches and improves the English language and culture education of English major students expanding that education and relevant practical training to fit much better the international and intercultural contexts of communication in English.

The article examines the place of graphic design in modern post-industrial society, extending beyond purely applied art and aspiring to play the role of an expert in the interiors of human existence, determining the social and cultural status of an individual. It is argued that graphic design, organically integrating into contexts and actively responding to the challenges of such a social-decorative phenomenon as fashion, plays a significant role in shaping taste culture. This attests to the multiplicity of ambivalent cultural manifestations (...) of graphic design. Special attention is given to identifying the functional potential of graphic design in creating cross-cutting trends that, through non-verbal means of communication, can form and maintain social and cultural unity. In connection with this, an analysis of graphic design is carried out through the prism of philosophical communication, allowing the identification of graphic design as the most effective practice of nonverbal communication and information visualization in post-industrial society. It is determined that graphic design is capable not only of generating new meanings but also of creating communicative gaps. Given this specificity, the article particularly focuses on identifying the educational and upbringing potential of graphic design. It is demonstrated that the process of creating visual images and their subsequent interpretation by consumers of graphic information depends not only on the aesthetic taste, ethical beliefs, and humanistic orientation of the designer (visualizer) but also on their educational and upbringing potential. The necessity of strengthening humanistic orientations in modern Ukrainian design and art education is emphasized. (shrink)

The authors investigated the relevance of consequentialism in commercial space exploration as well as in the actively developing space market. The authors conclude that space expansion and colonization of space objects will lead to a revision of the foundational consequentialism provisions. Consequentialism, formed during the history of terrestrial civilization, loses its effectiveness under conditions of space commercialization. The basics of planetary thinking are different from those of cosmic thinking. Therefore, considering the meaning of the terms “cosmic expansion” and “colonization of (...) the cosmos” through the existing theory of consequentialism faces serious contradictions. There is a range of problems that are not explored in modern philosophy and ethics due to the lack of an empirical basis for philosophical analysis. (shrink)

We propose that a top priority of the cerebral cortex must be the discovery and explicit representation of the environmental variables that contribute as major factors to environmental regularities. Any neural representation in which such variables are represented only implicitly (thus requiring extra computing to use them) will make the regularities more complex and therefore more difficult, if not impossible, to learn. The task of discovering such important environmental variables is not an easy one, since their existence is only indirectly (...) suggested by the sensory input patterns the cortex receives – these variables are “hidden.” We present a candidate computational strategy for (1) discovering regularity-simplifying environmental variables, (2) learning the regularities, and (3) using regularities in perceptual and decision-making tasks. The SINBAD computational model discovers useful environmental variables through a search for different, but nevertheless highly correlated functions of any kind over non-overlapping subsets of the known variables, this being indicative of some important environmental variable that is responsible for the correlation. We suggest that such a search is performed in the neocortex by the dendritic trees of individual pyramidal cells. According to the SINBAD model, the basic function of each pyramidal cell is (1) to discover and represent one of the regularity-simplifying environmental variables, and (2) to learn to infer the state of its variable from the states of other variables, represented by other pyramidal cells. A network of such cells – each cell just attending to representation of its variable – can function as a sophisticated and useful inferential model of the outside world. (shrink)

The article considers possibility of applying the concept of descriptive metaphysics to the project of Kant's transcendental philosophy. According to analytical philosophy, descriptive metaphysics is the description of structures of thinking about the world. The basis for describing acts of thinking about the world from Kant's point of view is the description of forms of intuition. Transcendental (descriptive) analysis of understanding must be preceded by transcendental (descriptive) aesthetics as an investigation of pure intuitions of space and time. Phenomenon of time (...) is considered as a condition for determining the concepts "judgment", "category of understanding", "pure understanding" and "object of knowledge". (shrink)

Small cities have a unique socio-economic and cultural potential for developing Russian regions, which is manifested in their unique features: com- pactness, historical heritage, the existence of rare industries and the local economy. At the same time, today in Russia the realization of their potential is primarily hindered by the existing system of politi- cal institutions and practices. The purpose of the work is to analyze the economic potential of small cities. The paper explores the potential for the devel- opment (...) of small cities in relation to the Russian context. So, the authors consider the features of small cities and highlight their economic, social and political problems. As illustrated by the successful ones, the potential of small cities in various sectors of the economy (primary, secondary and tertiary) is analyzed. The practical significance of the study lies in the possibility of using the studied experi- ence in developing the potential of small cities in various sectors of the economy in the practice of Russian management. As a result, it is concluded that small cities as such can be economically and socially efficient settlements, that is, they can be a completely competitive urbanized unit. However, the tools for the development of such territories should be focused on supporting the promising areas of development, providing an opportunity for independent and responsible development.

Since Descartes “separation” of the Soul from the Body, we observe a complete confusion in their causal, functional, and semiotic relationships. However, in modern knowledge (about the informational activity of the human brain, the functional and causal properties of its neural networks, the functions of psychic phenomena during the processing of information in it, about the causal “ability” of information) it is time to put an end to this problem. Here, in order to explain what I am talking about, I (...) will use the notion of “information” (which had been unknown by Descartes) regarding the “dispute” between Mind & Body (the Physicality and the Mentality) for “the right” to be a more fundamental ontology of Reality. I will do this by introducing an “arbitrator” — the Objective Reality. This goal is achieved through the study of information activity of the human brain. In the process of this study, it turns out that the information activity of the brain in principle cannot be carried out without mental phenomena. That is, it turns out that the classical physical causality, which operates in the neural networks of the brain, is not able, by itself, without mental phenomena, to implement the information operations that the human brain actually performs. It also turns out that the functional inclusion of mental phenomena (at least, the phenomena of subjective evaluation and mental images) in the neurophysiologic (by and large, physical) activity of the brain explains the possibility and necessity of functional inclusion in this information processing the phenomenon of freedom of choice. After all, the processing information in the brain through mental phenomena allows more than one degree of freedom than it is “allowed” by any physical process. (shrink)

Primatological and archaeological evidence along with anthropological accounts of hunter-gatherer societies indicate that lethal between-group violence may have been sufficiently frequent during our ancestral past to have shaped our evolved behavioral repertoire. Two simulations explore the possibility that heroism (risking one's life fighting for the group) evolved as a specialized form of altruism in response to war. We show that war selects strongly for heroism but only weakly for a domain-general altruistic propensity that promotes both heroism and other privately costly, (...) group-benefiting behaviors. A complementary analytical model shows that domain-specific heroism should evolve more readily when groups are small and mortality in defeated groups is high, features that are plausibly characteristic of our collective ancestral past.

This article is dedicated to Nikolai O. Lossky’s intuitivism and personalism and their significance in the context of Russian philosophy. The author demonstrates how Lossky’s study of Russian philosophy influenced his work and allowed him to take a second look at a number of philosophical issues, indicating ways to develop them further. As a result of his research, Lossky discovered ideas close to his own in the works of various other Russian philosophers. Lossky became especially interested in two authors, Vladimir (...) S. Solovyov and Fyodor M. Dostoevsky. He created interpretations that examined Solovyov’s philosophy and Dostoevsky’s works from the positions of intuitivism and personalism. The study of Russian thought Lossky undertook in his book History of Russian Philosophy gave him a strong impetus for developing his own philosophical views, which were aimed at bringing philosophy and religion into closer proximity.

It was shown in [3] (see also [5]) that there is a duality between the category of bounded distributive lattices endowed with a join-homomorphism and the category of Priestley spaces endowed with a Priestley relation. In this paper, bounded distributive lattices endowed with a join-homomorphism, are considered as algebras and we characterize the congruences of these algebras in terms of the mentioned duality and certain closed subsets of Priestley spaces. This enable us to characterize the simple and subdirectly irreducible algebras. (...) In particular, Priestley relations enable us to characterize the congruence lattice of the Q-distributive lattices considered in [4]. Moreover, these results give us an effective method to characterize the simple and subdirectly irreducible monadic De Morgan algebras [7].The duality considered in [4], was obtained in terms of the range of the quantifiers, and such a duality was enough to obtain the simple and subdirectly irreducible algebras, but not to characterize the congruences.

This article addresses the famous 1910 debate between Vladimir F. Ern and Semyon L. Frank centered around the problem of identifying the distinguishing features of Russian philosophy. The debate was a continuation of Ern’s debates with Russian philosophers associated with the international journal Logos (Sergei I. Hessen, Fyodor A. Stepun, Boris V. Yakovenko, and others). The author shows that Ern’s understanding of an original Russian philosophy is organically related to his overall philosophical doctrine. As for Frank, his views during the (...) 1910s on the distinguishing features of Russian philosophy were different in nature. It is worth noting that in the 1920s articles written during his émigré period, Frank’s views on the distinguishing features of Russian philosophy undergo a decisive change. Frank’s new ideas about Russian philosophy turn out to be extremely close to those of his late opponent, both on the whole and in the details. At the same time, Frank’s overall philosophical views do not undergo as dramatic a change and develop in a fully evolutionary mode. The author attempts to identify the reason for these changes.

This anthology of philosophical texts by Greek and Roman authors brings together works from the late fifth century BC to the sixth century AD that comment on major aesthetic issues such as the perception of beauty and harmony in music and the visual arts, structure and style in literature, and aesthetic judgement. It includes important texts by Plato and Aristotle on the status and the role of the arts in society and in education, and Longinus' reflections on the sublime in (...) literature, in addition to less well-known writings by Philodemus, Cicero, Seneca, Plotinus, Augustine and Proclus. Most of the texts have been newly translated for this volume, and some are available in English for the first time.

National scientists have elaborated the reform's gist, approaches, stages and consequences in the Ukrainian agricultural sector during the XX - XXI centuries. These studies have been conducted by N. Zhulkanych, S. Zhyvora, M. Zyza, M. Lendiel, E. Mazur, O. Malyarchuk, V. Nechytailo and many others. The paper aims to perform the comprehensive study of general trends and peculiar features of the agricultural development of the Ukrainian SSR in 1963-1990 and to define actual advances and drawbacks on the basis of analysis (...) of historical records and scientific literature. The object of research is agriculture as part of socialist economy in the USSR. The subject of research is the implementation features of agricultural policy of the Soviet power in the Ukrainian SSR, using the Western region of the Republic as an example. The economic strategy of the Soviet power involved a long-term industrialization of the agricultural sector. A distinguishing feature of the industrialization process was the use of systems of machinery in all branches of agriculture. The technological chain had to embrace the process from the sporadic application of machinery to the overall mechanization and automation of crop and livestock farming. The industrial background of production predetermined the implementation of the system of machinery with extensive power consumption, i.e. with the new technical bases. The resolutions of the March Plenum of the CPSU Central Committee defined the economic priorities and capacity development of the Republic. Capital investments were the economic basis for the increase of production potential of collective and state farms, solution of social problems in rural regions. The land productivity was increased mainly by means of land reclamation and production chemization, use of organic and mineral fertilizers, pesticides, fungicides, etc. The supply of mineral fertilizers increased, but most of them were of low quality, non-concentrated and unbalanced in nutritional ingredients. In its turn it caused irreparable damage to the environment and polluted agricultural products with chemicals. The chemization undermined the population health and disrupted the ecological balance. Despite ultimate achievements in the rise of the industrial level of agriculture of the Ukrainian SSR, it didn't meet the needs of collective and state farms. A great number of labour-intensive processes in animal and crop farming were performed manually. In state farms, contrary to collective farms, the stock of tractors was newer, but much smaller. For many years the USSR was in the top ten countries of the world in terms of consumption of energy and proteins, contained in food products per capita. However, the food patterns were inconsistent with the scientifically grounded norm. Structural imbalance of the food ration was the manifestation of the food crisis in the USSR. To meet primary needs of Soviet citizens in food products the May Plenum of the CPSU Central Committee adopted the "Food Program of the USSR for the Period until 1990 and Measures of Its Implementation". The main issue of the Food program was to increase grain harvest. Grain production was the basis for food and fodder supply of the country. Alongside with a substantial increase in food products output in public economy the attention was given to the development of subsidiary individual holdings and fruit-and-vegetable cooperatives. The cooperatives and subsidiary holdings produced a great number of dairy and meat products, vegetables and fruits both for their own needs and for sale in collective farm markets. The state food program predetermined the solution of agricultural problems by means of formerly used methods. The major problem of agriculture had to be solved by means of increase in the gross grain harvest. Thus, the implementation of agricultural policy of Soviet power in the Ukrainian SSR lead to great changes in agricultural production. At that time there appeared such new branches of economy specialized in services to agricultural production as waterworks and land reclamation, feed mill industry, farm building, machine engineering for animal farming and fodder production, procurement of agricultural products and agricultural processing. The study of this policy implementation proves that the average annual rates of agricultural production increased but they were inconsistent with high investments. On the one hand, the Food program testified the "food crisis in the USSR", demonstrating the lag of the world socialist community from capitalist states. On the other hand, it had to increase the level of food self-sufficiency, decrease the procurement of agricultural products from abroad and promote the solution of the world food problem in general.

A structure (M, $ ,...) is called quasi-o-minimal if in any structure elementarily equivalent to it the definable subsets are exactly the Boolean combinations of 0-definable subsets and intervals. We give a series of natural examples of quasi-o-minimal structures which are not o-minimal; one of them is the ordered group of integers. We develop a technique to investigate quasi-o-minimality and use it to study quasi-o-minimal ordered groups (possibly with extra structure). Main results: any quasi-o-minimal ordered group is abelian; any quasi-o-minimal (...) ordered ring is a real closed field, or has zero multiplication; every quasi-o-minimal divisible ordered group is o-minimal; every quasi-o-minimal archimedian densely ordered group is divisible. We show that a counterpart of quasi-o-minimality in stability theory is the notion of theory of U-rank 1. (shrink)

The article investigates what happens when philosophy meets and begins to establish connections with two formal research methods such as game theory and network science. We use citation analysis to identify, among the articles published in Synthese and Philosophy of Science between 1985 and 2021, those that cite the specialistic literature in game theory and network science. Then, we investigate the structure of the two corpora thus identified by bibliographic coupling and divide them into clusters of related papers by automatic (...) community detection. Lastly, we construct by the same bibliometric techniques a reference map of philosophy, on which we overlay our corpora to map the diffusion of game theory and network science in the various sub-areas of recent philosophy. Three main results derive from this study. Philosophers are interested not only in using and investigating game theory as a formal method belonging to applied mathematics and sharing many relevant features with social choice theory, but also in considering its applications in more empirically oriented disciplines such as social psychology, cognitive science, or biology. Philosophers focus on networks in two research contexts and in two different ways: in the debate on causality and scientific explanation, they consider the results of network science; in social epistemology, they employ network science as a formal tool. In the reference map, logic—whose use in philosophy dates back to a much earlier period—is distributed in a more uniform way than recently encountered disciplines such as game theory and network science. We conclude by discussing some methodological limitations of our bibliometric approach, especially with reference to the problem of field delineation. (shrink)

he model theory of groups of unitriangular matrices over rings is studied. An important tool in these studies is a new notion of a quasiunitriangular group. The models of the theory of all unitriangular groups are algebraically characterized; it turns out that all they are quasiunitriangular groups. It is proved that if R and S are domains or commutative associative rings then two quasiunitriangular groups over R and S are isomorphic only if R and S are isomorphic or antiisomorphic. This (...) algebraic result is new even for ordinary unitriangular groups. The groups elementarily equivalent to a single unitriangular group UTn are studied. If R is a skew field, they are of the form UTn, for some S ≡ R. In general, the situation is not so nice. Examples are constructed demonstrating that such a group need not be a unitriangular group over some ring; moreover, there are rings P and R such that UTn ≡ UTn, but UTn cannot be represented in the form UTn for S ≡ R. We also study the number of models in a power of the theory of a unitriangular group. In particular, we prove that, for any communicative associative ring R and any infinite power λ, I = I). We construct an associative ring such that I = 3 and I) = 2. We also study models of the theory of UTn in the case of categorical R. (shrink)

For a quasi variety of algebras K, the Higman Theorem is said to be true if every recursively presented K-algebra is embeddable into a finitely presented K-algebra; the Generalized Higman Theorem is said to be true if any K-algebra which is recursively presented over its finitely generated subalgebra is embeddable into a K-algebra which is finitely presented over this subalgebra. We suggest certain general conditions on K under which the Higman Theorem implies the Generalized Higman Theorem; a finitely generated K-algebra (...) A is embeddable into every existentially closed K-algebra containing a finitely generated K-algebra B if and only if the word problem for A is Q-reducible to the word problem for B. The quasi varieties of groups, torsion-free groups, and semigroups satisfy these conditions. (shrink)

Evasion of value added tax (VAT) is a pressing criminal justice problem; however, there still are no theoretical studies on the specific nature of this offense and the basis of its legal evaluation. This article is an attempt to explain the preconditions of the origin of this type of fraud and its connection with the Value Added Tax Law, to formulate the conceptual understanding of the offense, to reveal the important aspects of its legal evaluation and to discuss relevant examples (...) from the case-law. The preconditions of VAT fraud lie in the legal nature of tax administration and the particularity of VAT regulation creating opportunities to abuse the right of deducting the overpayment from the budget or reducing the tax payable. The system of tax crimes stipulated in the Criminal Code is not sufficient to properly assess the impact and danger of VAT fraud. The judicial practice considering VAT deception as property fraud is theoretically justified and welcome. (shrink)

Many nuclear proteins have been found recently to interact with short conserved sequences which are involved in regulating the transcription of various genes. Nuclear transcription factors may be arbitrarily subdivided into two groups, ubiquitous and tissue‐specific. The transcription of one gene is usually regulated by several factors which interact with different sequences located either in the promoter region of the gene or outside it. The appearance or disappearance of transcription factors for some genes corresponds to certain phases of cell differentiation (...) or dedifferentiation and even to individual stages of the cell cycle.
