ABSTRACTThe development of oceanography and meteorology has greatly benefited from satellite-based data of Earth’s atmosphere and ocean. Traditional Earth observation missions have utilised Sun-synchronous orbits with repeat ground tracks due to their advantages in visible and infrared wavelengths. However, diversification of observation wavelengths and massive deployment of miniaturised satellites are both enabling and necessitating new kinds of space missions. This paper proposes several unconventional satellite orbits intended for use in, but not limited to, Earth observation. This ‘toolbox’ of orbits and taxonomy thereof will thus support the definition of design requirements for the individual satellites in nano-satellite constellations developed by national space agencies, industries and academia.

AbstractESA and NASA are studying projects having a tremendous return on variable star research. Other national space agencies are also studying or developing projects of smaller costs but with impressive returns. The projects range from global Galactic surveys like the ESA mission GAIA which will give photometric time series for about 1 billion stars, to detailed pulsation-mode studies like the CNES mission COROT which could reach a photometric precision lower than 1 ppm. The presentation will emphasize the future astrometric, asteroseismological and planet detection missions.

This paper discusses the development and application of a Functionality Matrix (FM) technique to design requirements for a Cognitive Assistant (CA) to aid future long distance space missions. Future far-Earth space missions pose challenges due to communication delays between Mission Control and space crew. As communication delays increase, Mission Control is less able to support space crew in off-nominal situations. The FM technique was used to extrapolate the joint decision-making functions performed in current near-Earth operations to functions performed in future, far-Earth space operations, allocated between Mission Control, space crew, and potential automation. Data gathered from document analysis and interviews with astronauts were consolidated to generate the domain knowledge models of the collaborative decision-making process for current space operations. Each function in the decision-making process was examined to extrapolate the current collaborative work of Mission Control and space crew to future space operations under long time delays, when the role of Mission Control must change. The domain knowledge models were also used to identify the functions performed to resolve off-nominal situations in current operations that are most affected by long communication delays. The identified functions constituted the input for the FM. The responsibilities of Mission Control, space crew and CA were categorized in the FM as current and/or future space operations. The FM describes the shared responsibilities between space crew and Mission Control with and without CA support in space operations. The FM was used to describe functional design requirements, and will lead to the development of function allocation rules.

The article analyzes models of metaphorical description of sounds that are relevant to M. Vinhranovsky’s individual poetic picture of the world. It is determined that the most productive type of audio metaphorization is related to the verbalization of associative sound-to-nature relationships. Its relevance is determined by the collective (secured by verbal tradition) and individual (author) experience of perceiving objects of national space, such as river, sky, water, forest, grove, trees, as well as related phenomena of nature (wind, storm, thunder, rain). and living things (birds, animals, insects). The persistence of associations in the poetic texts motivated by this experience has been consistently confirmed. The collective and individual experience of perception of the phenomena of the nature of rain, thunderstorm, rain, wind, water motivates the active use of «sound» verbs, which metaphorize the various actions and intensity of manifestation of these phenomena. The stylistic performance of common linguistic formulas with stylistically neutral verbs – carriers of the archives of ‘sounds of nature’ is traced. It is proved that an important fragment of the sound definition of the world in the national linguistic-poetic practice and in the idyllic style of M. Vinhranovsky as its symbolic fragment is the image of “silence”. Updating the “zero” manifestation of audio semantics, it creates a semantic opposition to images with the seven “sound”. The aesthetic unfolding of the image of silence in various structural metaphorical structures: verbal predicative, verbal object, oxymoronic, tautological is attested. Analyzed metaphors confirm that the aesthetized verbalization of sound impressions is one of the dominants of M. Vinhranovsky’s individual poetic phrase, in which the metaphors with the seven ‘sound’ are indisputable artistic dominants.

Why does writing of the death penalty demand the first-person treatment that it also excludes? The article investigates the role played by the autobiographical subject in Derrida's The Death Penalty, Volume I, where the confessing ‘I’ doubly supplements the philosophical investigation into what Derrida sees as a trend toward the worldwide abolition of the death penalty: first, to bring out the harmonies or discrepancies between the individual subject's beliefs, anxieties, desires and interests with respect to the death penalty and the state's exercise of its sovereignty in applying it; and second, to provide a new definition of the subject as haunted, as one that has been, but is no longer, subject to the death penalty, in the light of the worldwide abolition currently underway.

Персонологическая интерпретация текстов предполагает реализацию общенаучных, а также специфических для персонологии, герменевтических установок, к которым относятся: установка на интерпретацию текста как исследование, установка на разнообразие герменевтических действий с текстом, установка на выявление неисследованных содержаний текста, установка на творческое постижение тайн текста, установка на целостное отношение к личности и "Я" автора текста, установка на выявление способности автора быть "практикующим феноменологом", установка на определение места изучаемого текста в континууме текстовых репрезентаций "личности", установка на соотнесение своего понимания текста с другими интерпретациями и их интеграцию, установка на раскрытие сущности авторской "идеи личности", возможное только в единстве интерпретаций, установка на построение и применение герменевтической модели, определяющей процедуру интерпретации как исследования и творчества, установка на определение места проделанного герменевтического поиска в культуре познания и жизни личности, установка на интерпретацию различных видов "текстов личности". Personological interpretation of texts suggests the implementation of the general scientific and also hermeneutical settings specific for Personology which include the setting of the interpretation of the text as a research, setting of a variety of hermeneutical actions with the text, setting to identify unexplored contents of the text, setting of the creative comprehension of the mysteries of the text, setting of the integrity of the attitude of the individual and the "I" of the author of the text, setting to reveal the author's ability to be "practicing phenomenologist", setting of the definition of the place in the text in the continuum of textual representations of the "personality", setting in the correlation of the understanding of the text with other interpretations and their integration, setting of the disclosure of the author's "ideas person" is possible only in the unity of interpretation, setting of the construction and usage of hermeneutical models defining the procedure for the interpretation of both studies and work, the setting to determine the place of hermeneutical research in culture and knowledge of a person's life, setting of the interpretation of various types of "texts of the individual."

The problem of identity is an issue of contemporary society that is not only expressed in daily life concerns but also in discourses of politics and social movements. Nevertheless, the I and the needs of self-fulfillment usually are taken for granted. This paper offers thoughts regarding individual identity based on Niklas Luhmann’s systems theory. From this perspective, identity is not observed as a thing or as a subject, but rather as a “selfillusion” of a system of consciousness, which differentiates itself from the world, event after event, in a contingent way. As concerns the definition  of contents of self-identity, the structures of social systems define who is a person, how he or she should act, and how much esteem he or she should receive. These structures are adopted by consciousness as its own identity structures; however, some social contexts are more relevant for self-identity construction than others. Moral communication increases the probability that structure appropriation takes place, since the emotional element of identity is linked to the esteem/misesteem received by the individual from the interactions in which he or she participates.

In this paper, the author examines public service as depicted in the television series Buffy the Vampire Slayer (BtVS). First, she shows how slaying meets the economist’s definition of a public good, using the BtVS episode “Flooded” (6.04). Second, she discusses public service motivation (PSM) to determine whether or not Buffy, a public servant, operates from a public service ethic. Relying on established measures and evidence from shooting scripts and episode transcripts, the author concludes Buffy is a public servant motivated by a public service ethic. In this way, BtVS informs scholarship on public service by broadening the concept of PSM beyond the public sector; prompting one to wonder whether it is located in a sector, an occupation, or in the individual. These conclusions allow the author to situate Buffy alongside other idealized public servants in American popular culture.

This chapter discusses the implications of Spinoza’s concept of individual bodies, as introduced in the definition of individuum in the physical digression. It begins by showing that this definition allows for an extremely wide application of the term; accordingly, very different sorts of physical entities can be described as Spinozistic individuals. Given the quite distinct use of the terms divisibilis and indivisibilis in his metaphysics, however, the chapter argues that the physical concept of individuality is not universally applied in the Ethics but reserved for physical or natural-philosophical considerations. The chapter concludes with a discussion of the problem of collective individuals. It is argued that, while societies or states are described as individual bodies, they do not constitute individual group minds in the strict sense of the term for Spinoza. This in turn indicates that minds are not individuated in the same way as bodies.
