The enrichment of the protected Borovoe Lake with nutrients has taken place within the last 100 years, from the moment the first resort was formed on its shores. The purpose of this study was to assess the current ecological state of Borovoe based on the structure of zooplankton. According to the chemical data, in the summer of 2019, the content of nutrients in the water was, relatively, not high; the content of heavy metals was very low. Twenty-seven species were found in zooplankton. The average abundance of zooplankton was 988.8 thousand ind./m3 with a biomass of 1.52 g/m3. Rotifera dominated. Cladocera sub-dominated. The Shannon index values were 2.31 bit/ind. and 2.57 bit/mg; the values of Clarke’s W-statistics and Δ-Shannon were negative. The abundance of zooplankton increased more than nine times, but the average individual mass of an organism decreased from 0.0112 to 0.0016 mg over the past decade. Despite the relatively low content of nutrients, the structure of zooplankton demonstrated that the nutritional load on Lake Borovoe is currently close to critical. Statistical mapping of the data and redundancy analysis (RDA) showed that the primary source of lake pollution is the village of Borovoe and sanatoriums located on the southeast and northwest coasts.

The primary source material for the art historian is of course the work of art, and this in itself places him in a fortunate position because the permanent relevance of the work of art is, I take it, self-evident. For the art historian, the work of art is an historical fact, pre-selected for generally accepted aesthetic reasons. But the work of art has no absolute meaning: it does not exist in a vacuum. It has both what we might call a history and a geography—the history being that record of interpretation and evaluation which accrues to the work of art from the moment of its creation down to the present day; and the geography being the particular artistic and social context of its original creation. The history can at times be very misleading: it is obvious that each generation is going to interpret the past as it wishes, and no judgment can be objective. So it is the geography that is more important, and this is extremely difficult to define. But if we are to understand the work of art, we need to enquire into the circumstances of its creation: we must ask, what did this painting or sculpture or building signify when it first appeared? Only from such specific investigations can one proceed to general propositions about the state of art at any particular moment, and perhaps also about the state of society which produced the art.

Abstract. The article analyzes the autobiography of the famous Russian philosopher, theologian and scientist Pavel Florensky, as well as those of his texts that retain traces of memories. According to Florensky, the personal biography is based on family history and continues in children. He addresses his own biography to his children. Memories based on diary entries are designed as a memory diary, that is, as material for future memories. The past becomes actual in autobiography, turns into a kind of present. The past, from the point of view of its realization in the present, gains meaning and significance. The au-thor is active in relation to his own past, transforming it from a collection of disparate facts into a se-quence of events. A person can only see the true meaning of such events from a great distance. Therefore, the philosopher remembers not so much the circumstances of his life as the inner impressions of the en-counter with reality. The most powerful personality-forming experiences are associated with childhood. Even the moment of birth can decisively affect the character of a person and the range of his interests. The foundations of a person's worldview are laid precisely in childhood. Florensky not only writes mem-oirs about himself, but also tries to analyze the problems of time and memory. A person is immersed in time, but he is able to move into the past through memory and into the future through faith. An autobi-ography can never be written to the end because its author lives on. However, reaching the depths of life, he is able to build his path in such a way that at the end of this path he will unite with the fullness of time, with eternity.

In this retrospective piece, the Guest Editor of the first number of CounterText (a special issue titled Postcolonial Springs) looks back at the past five years from various scholarly and personal perspectives. He places particular focus on an event that took place mid-way between the 2011 uprisings across a number of Arab countries and the moment of writing: the March 2015 terror attack on the Bardo National Museum in Tunis, which killed twenty-two people and had a profound effect on Tunisian popular consciousness and that of the post-2011 Arab nations. In this context, the author argues for a renewed perspective on memoir as at once a memorial practice and a political gesture in writing, one that exceeds concerns of genre and form to encompass an ongoing project of political re-cognition following events that continue to remap the agenda for the region. The piece makes a brief final pitch for Europe's need to re-cognise, within those modes of ‘articulacy-in-difficulty’ active on its southern borders, specific answers to its own present quandaries.

The article examines the Genesis of the institution of jury trial in the Russian Empire from the moment of its introduction to the end of the Provisional government. It is noted that the emergence of a trial with the participation of jurors was influenced by Western models of the judicial process, and the forms of participation of citizens in the administration of justice that previously existed on the territory of the Russian state were taken into account. The role that the jury system has played with some success in the search for truth, justice, and the implementation of effective and independent justice in the past centuries is particularly highlighted.

In the past centuries, small towns in Podlaskie Voivodeship were dominated by wooden buildings. Nowadays, there are not many of them left. However, they can still be found in the centers of towns, including some market squares. These are often inconspicuous objects, mainly wooden houses. This paper discusses the issue of the significance of wooden buildings, especially houses, in maintaining and restoring historic values of market spaces in small towns of Podlaskie Voivodeship in the examples of Bielsk Podlaski and Kleszczele. The research determined the moment of rapid changes, during which most marketplace buildings lost their historic form. The existing condition was analyzed in terms of its historical values. Conclusions were formulated on the scope and type of restoration works for individual market squares. Finally, general conclusions from the research on the market squares of Bielsk Podlaski and Kleszczele were presented.

ABSTRACT When European colonists arrived in the late 19th century, large villages dotted the coastline of the Gulf of Papua (southern Papua New Guinea). These central places sustained long-distance exchange and decade-spanning ceremonial cycles. Besides ethnohistoric records, little is known of the villages’ antiquity, spatiality, or development. Here we combine oral traditional and 14C chronological evidence to investigate the spatial history of two ancestral village sites in Orokolo Bay: Popo and Mirimua Mapoe. A Bayesian model composed of 35 14C assays from seven excavations, alongside the oral traditional accounts, demonstrates that people lived at Popo from 765–575 cal BP until 220–40 cal BP, at which time they moved southwards to Mirimua Mapoe. The village of Popo spanned ca. 34 ha and was composed of various estates, each occupied by a different tribe. Through time, the inhabitants of Popo transformed (e.g., expanded, contracted, and shifted) the village to manage social and ceremonial priorities, long-distance exchange opportunities and changing marine environments. Ours is a crucial case study of how oral traditional ways of understanding the past interrelate with the information generated by Bayesian 14C analyses. We conclude by reflecting on the limitations, strengths, and uncertainties inherent to these forms of chronological knowledge.

This paper presents a short history of Polish formations protecting the governing bodies of the state, starting from the moment Poland regained independence at the end of the twentieth century. The considerations are presented against the rules and principles of the functioning of the state security system, with particular emphasis on the control subsystem. This paper demonstrates the need to research attitudes to safety in the past, in order to develop and apply effective contemporary solutions. The considerations contained in it also concern the existing threats to the management of state organs. They may contribute to further discussions on the purpose and rules of operation of the formation which is supposed to protect the most important people in the state.

History is constructed by people who study the past. It is created through working on both primary and secondary sources that historians use to learn about people, events, and everyday life in the past. Just like detectives, historians look at clues, sift through evidence, and make their own interpretations. Historical knowledge is, therefore, the outcome of a process of enquiry. During last century, the teaching of history has changed considerably. The use of sources, viz. textual, visual, and oral, in school classrooms in many parts of the world has already become an essential part of teaching history. However, in India, it is only a recent phenomenon. Introducing students to primary sources and making them a regular part of classroom lessons help students develop critical thinking and deductive reasoning skills. These will be useful throughout their lives. This paper highlights the benefits of using primary source materials in a history classroom and provides the teacher, with practical suggestions and examples of how to do this.

Discussions of the authorship of the Gospel of John must answer two questions: who is the Beloved Disciple who is portrayed as the book’s primary source of information, and how is this individual related to the author, John the evangelist? On the first question, scholars are divided on whether the Beloved Disciple is a real historical individual or an ideal symbolic figure. Data from the text itself and from social-science perspectives on the reputations of key figures from the past suggest that both are correct: the Beloved Disciple was a legendary associate of Jesus whose presentation reflects his reputation as a source of information that was critical to the Johannine theological outlook. On the second question, data suggests that the evangelist was not the Beloved Disciple but rather a disciple of that individual, perhaps basing his own book on an earlier document produced by the Beloved Disciple.

This article undertakes a philosophical exploration of the act we know, or think we know, as ‘dressing’. Inhabiting, in thought, the moment in which we dress, I examine some of its constituent mechanisms, attending to the impulses by which dressing is generated out of subjective experience.  When those impulses are temporally marked, as they are in the case of retro dress, this generation is a two-pronged process, in which the holding of the body in time, and the holding of time in the body, recalibrate one another. The process of ‘dressing,’ in this understanding, has a reflexivity which is double; it entails the turning of the body, with dress as medium, towards itself, and the turning of present experience towards some felt notion of the past. Reflexively dressing, we are always becoming ourselves, and becoming other than ourselves, at once; a movement of circuitous internalisation and externalisation by which the ambiguation inherent in material experience is realised.
