Exceptionally preserved fossils provide major insights into the evolutionary history of life. Microbial activity is thought to play a pivotal role in both the decay of organisms and the preservation of soft tissue in the fossil record, though this has been the subject of very little experimental investigation. To remedy this, we undertook an experimental study of the decay of the brine shrimp Artemia , examining the roles of autolysis, microbial activity, oxygen diffusion and reducing conditions. Our findings indicate that endogenous gut bacteria are the main factor controlling decay. Following gut wall rupture, but prior to cuticle failure, gut-derived microbes spread into the body cavity, consuming tissues and forming biofilms capable of mediating authigenic mineralization, that pseudomorph tissues and structures such as limbs and the haemocoel. These observations explain patterns observed in exceptionally preserved fossil arthropods. For example, guts are preserved relatively frequently, while preservation of other internal anatomy is rare. They also suggest that gut-derived microbes play a key role in the preservation of internal anatomy and that differential preservation between exceptional deposits might be because of factors that control autolysis and microbial activity. The findings also suggest that the evolution of a through gut and its bacterial microflora increased the potential for exceptional fossil preservation in bilaterians, providing one explanation for the extreme rarity of internal preservation in those animals that lack a through gut.

This article explores some textual dimensions of what I argue is a crucial moment in the history of the Anglo-Saxon subject. For purposes of temporal triangulation, I would locate this moment between roughly 970 and 1035, though these dates function merely as crude, if potent, signposts: the years 970×973 mark the adoption of the Regularis concordia, the ecclesiastical agreement on the practice of a reformed (and markedly continental) monasticism, and 1035 marks the death of Cnut, the Danish king of England, whose laws encode a change in the understanding of the individual before the law. These dates bracket a rich and chaotic time in England: the apex of the project of reform, a flourishing monastic culture, efflorescence of both Latin and vernacular literatures, remarkable manuscript production, but also the renewal of the Viking wars that seemed at times to be signs of the apocalypse and that ultimately would put a Dane on the throne of England. These dates point to two powerful and continuing sets of interests in late Anglo-Saxon England, ecclesiastical and secular, monastic and royal, whose relationships were never simple. This exploration of the subject in Anglo-Saxon England as it is illuminated by the law draws on texts associated with each of these interests and argues their interconnection. Its point of departure will be the body – the way it is configured, regarded, regulated and read in late Anglo-Saxon England. It focuses in particular on the use to which the body is put in juridical discourse: both the increasing role of the body in schemes of inquiry and of punishment and the ways in which the body comes to be used to know and control the subject.

This article is devoted to the contemporary historiography of higher school for energetics in USSR and the Russian federation. The subject of this research is comprised of formation of modern scientific perceptions on emergence and development of Russian system of training energy personnel. The object of this research is the body of 1990s-2000s publications of historic and multidisciplinary profile on the contemporary history of higher energy education and university energetics in Russia. The goal of this research is to determine the main problematic vectors and theoretical approaches forming in the process of scientific research of this topic, as well as understanding of the results and further prospects of its development. The novelty of this research consists in determining, systematizing and analyzing the content of the body of historiographical sources on history of Russian energetics and education during XX and XXI centuries. The authors conclude that within the framework of this historiographical branch, there is a current scientific base that allows transitioning to a new level of discovery and theoretical generalization of materials. It seems relevant to transition from “milestone stories” of universities and departments to study of the role of higher education and academic science in the process of implementation of state energy policy in Russia, as well as development of international energy dialogue.

This article investigates the ways in which the work of The Body Politic (TBP), the first major lesbian and gay newspaper in Canada, comes to be commemorated in queer publics and how it figures in the memories of those who were involved in producing the paper. In revisiting a critical point in the history of TBP from 1985 when controversy erupted over race and racism within the editorial collective, this discussion considers the role of memory in the reproduction of whiteness and in the rupture of standard narratives about the past. As the controversy continues to haunt contemporary queer activism in Canada, the productive work of memory must be considered an essential aspect of how, when and for what reasons the work of TBP comes to be commemorated. By revisiting the events of 1985 and by sifting through interviews with individuals who contributed to the work of TBP, this article complicates the narrative of TBP as a bluntly racist endeavour whilst questioning the white privilege and racially-charged demands that undergird its commemoration. The work of producing and preserving queer history is a vital means of challenging the intentional and strategic erasure of queer existence, but those who engage in such efforts must remain attentive to the unequal terrain of social relations within which remembering forms its objects.

Objective: To report a case of young male with stroke and bilateral internal carotid artery (ICA) dissection. Background: Cervical Artery Dissection in Stroke Study trial has provided some insight on management of patients with ICA dissection. However, there is a need to modify the management strategies as per specific clinical scenario. Design/Methods: Case report and literature review. Results: A 45-year-old male presented with 1 month old history of acute onset numbness of right half of the body with slurring of speech. Computed tomography angiography showed complete occlusion of left cervical ICA just beyond origin with presence of fusiform dilatation and spiral flap in right extracranial cervical ICA. The patient was started on antiplatelets and taken for endovascular procedure using 2-mesh-based carotid stents. Patient was discharged after 3 days on antiplatelet therapy. At 1-year follow-up, there were no fresh symptoms. Conclusion: This case emphasizes the role of successful endovascular management of carotid dissection in a young male. These clinical situations may not be fully represented in trials, and a case-based approach is required.

Science, technology and human values have been the subject of enquiry in the last few years for social scientists and eventually the relationship between science and gender is the subject of an ongoing debate. This is due to the event of globalization which led to the exponential growth of new technologies like assisted reproductive technology (ART). ART, one of the most iconic technological innovations of the twentieth century, has become increasingly a normal social fact of life. Since ART invades multiple human discourses—thereby transforming culture, society and politics—it is important what is sociological about ART as well as what is biological. This article argues in commendation of sociology of technology, which is alert to its democratic potential but does not concurrently conceal the historical and continuing role of technology in legitimizing gender discrimination. The article draws the empirical insights from local articulations (i.e., Odisha state in eastern India) for the understandings of motherhood, freedom and choice, reproductive right and rights over the body to which ART has contributed. Sociologically, the article has been supplemented within the broader perspectives of determinism, compatibilism alongside feminism.

Purpose – The purpose of this paper is to examine how the boundaries of rhetoric have excluded important theoretical and practical subjects and how these subjects are recuperated and extended since the twentieth century. Its purpose is to foster the awareness on emerging new trends of rhetoric. Design/methodology/approach – The methodology is based on an interpretation of the history of rhetoric and on the construction of a conceptual framework of the rhetoric of judgment, which is introduced in this paper. Findings – On the subject of the extension of rhetoric from public speeches to any kinds of persuasive situations, the paper emphasizes some stimulating relationships between the theory of communication and rhetoric. On the exclusion and recuperation of the subject of rhetorical arguments, it presents the changing relationships between rhetoric and dialectics and emphasizes the role of rhetoric in scientific research. On the introduction of rhetoric of judgment and meanings it creates a conceptual framework based on a re-examination of the concept of judgment and the phenomenological foundations of the interpretative methods of social sciences by Alfred Schutz, relating them to symbolic interactionism and theories of the self. Originality/value – The study on the changing boundaries of rhetoric and the introduction of the rhetoric of judgment offers a new view on the present theoretical and practical development of rhetoric, which opens new subjects of research and new fields of applications.

The goal of this article consists in demonstration of the impact of research in the field of history and theory of law alongside the hermeneutics of Emilio Betti impacted the vector of this philosophical thought. The subject of this article is the lectures read by Emilio Betti (prolusioni) in 1927 and 1948, as well as his writings of 1949 and 1962. Analysis is conducted on the succession of Betti's ideas in these works, which is traced despite the discrepancy in their theme (legal and philosophical). The author indicates “legal” origin of the canons of Bettis’ hermeneutics, namely the canon of autonomy of the object. Emphasis is placed on the problem of objectivity in Betti's theory, as well as on dialectical tension between the historicity of the interpreted subject and strangeness of the object that accompanies legal, as well as any other type of interpretation. The article reveals the key moment of Betti's criticism of Hans-Georg Gadamer. Regarding the question of historicity of the subject of interpretation. The conclusion is made that the origin of the general theory of interpretation lies in the approaches and methods developed and implemented by Betti back in legal hermeneutics and in studying history of law.   Betti's philosophical theory was significantly affected by the idea on the role of modern legal dogma in interpretation of the history of law. Namely this idea that contains the principle of historicity of the subject of interpretation, which commenced  the general hermeneutical theory of Emilio Betti, was realized in canon of the relevance of understanding in the lecture in 1948, and later in the “general theory of interpretation”. The author also underlines that the question of objectivity of understanding, which has crucial practical importance in legal hermeneutics, was transmitted into the philosophical works of E. Betti, finding reflection in dialectic of the subject and object of interpretation.

The interdisciplinary character of the science of language causes great difficulties in bibliographic support in this field. The object of bibliographing in linguistics is not only literature on the language, but also a variety of linguistic resources, which represent a special object to study a branch of linguistics - lexicography. Bibliography of linguistics is the least studied field by specialists among humanitarian bibliographic complexes. The paper first studied the array of domestic bibliographic sources for more than 150 years; the most significant of them are shown. The subject of research is national bibliographic resources in the linguistics field. The objective is to characterize the historical development of the linguistic bibliography in Russia. To achieve this goal we had to solve a number of tasks: identify existing sources for ongoing historical research; to trace the history of forming bibliographic sources, bibliography of bibliographies of linguistics; to form and analyze the body of bibliographic materials; to characterize the problematic areas in the bibliographic software of linguistics. Using the bibliometric analysis it was studied an array of bibliographic products published between 1860 and 2013, the dynamics of bibliographic resources formation was determined, the degree of bibliographic support of some topics and issues in linguistic science and prior directions of their development were revealed. The main results of the study should be considered: 1. The nuclear of fundamental indices on general and applied linguistics is singled out in analyzed literature sources covering the period 1918-1977, as well as in Slavic linguistics for 1825-1981. The complex of current and retrospective bibliographic products was formed and replenished in the country in 1963-1988. 2. The largest share of bibliographic sources in linguistics is presented by book and article bibliography (over 70%), many of which remain bibliographically unrecorded and unused. 3. The following subject areas of linguistics are considered to be bibliographically supported: inter-linguistics, culture of speech and language norms, lexicography, linguistic geography, linguistics regional geography, onomastics. 4. An obvious need to continue the index or database of bibliographic aids in the field of linguistics over the past 50 years is marked. 5. Further development of the linguistics bibliography is impossible to imagine without creating an electronic guide on the bibliographic resources of linguistics, which would reflect the diversity of bibliographical resources and provide their rich information potential for professionals and remote users

In his Bibliotheca historica, Diodorus Siculus described a peculiar Egyptian custom of judging all the dead (including the pharaohs) before their burial. The Greek historian saw it as a guarantee of Egypt’s prosperity, since the fear of being deprived of the right to burial served as a moral imperative. This story of an Egyptian custom fascinated the early modern authors, from lawyers to novelists, who often retold it in their own manner. Their interpretations varied depending on the political context: from the traditional “lesson to sovereigns” to a reassessment of the role of the subject and the duties of the orator. This article traces several intellectual trajectories that show the use and misuse of this Egyptian custom from Montaigne to Bossuet and then to Rousseau—and finally its adaptation by Pushkin and Vyazemsky, who most likely became acquainted with it through the mediation of French literature. The article was written in the framework (and with the generous support) of the RANEPA (ШАГИ РАНХиГС) state assignment research program. KEYWORDS: 16th to 19th-Century European and Russian Literature, Diodorus Siculus (1st century BC), Jean-Jacques Rousseau (1712—1778), Alexander Pushkin (1799—1837), Prince Pyotr Vyazemsky (1792—1878), Egyptian Сourt, Locus communis, Political Rhetoric, Literary Criticism, Pantheonization, History of Ideas.

Givenness is probably an odd term in methodology, but not in phenomenology. The long history of subjectivism in philosophy faces confrontations from Derrida's deconstruction. This history also results in a sort of mutual exclusion between philosophy and theology. The concept of the subject becomes a problem for both, but frequently it is safeguarded for the sake of a more universal 'objectivity'. The phenomenological tendency towards phenomenon, more than towards the experiencing subject and more than anything regarded as object, provokes some philosophical focus on the emancipation of the phenomena. Marion pushes phenomenology to its limits, to the extent that he is suspected of undermining the role of the subject in contemporary philosophical discourse. He reacts to Derrida's deconstruction, which was also criticised for not offering a way out of the labyrinth from the collapse of traditional thoughts. Marion is quite consistent with his phenomenology, namely in offering a way out for the subject to be a witness, and reminds that philosophy should be more appreciative of phenomena. The term saturated phenomenon represents his philosophical thinking that can be regarded as a methodological approach to respect, and not to dominate, reality. Being a witness is not the same as playing a critic on reality. This could be a useful stance for philosophers as well as theologians in the presence of the phenomena they cannot master, namely, the given phenomena.
