This short review discusses current understanding of the history, anatomy and taxonomy of the lower Wealden Groupaged (Valanginian ~141–137Ma) iguanodontian dinosaurs from southern England. English Wealden iguanodontian taxonomy has been the subject of comment and scrutiny since the latter half of the 19 th century. As proposed over two decades ago, iguanodontians recovered from quarries across this geographic region can be subdivided into anatomically and chronologically distinct assemblages. A review of the lower Wealden Group (Valanginian) assemblage (formerly understood to comprise the relatively poorly known and understood taxa Iguanodon dawsoni, Iguanodon fittoni and Iguanodon hollingtoniensis) establishes the presence of two diagnosable taxa: Barilium dawsoni (Lydekker, 1888) comb. nov. and Hypselospinus fittoni (Lydekker, 1889) comb. nov. The upper Wealden Group (Hauterivian–Lower Aptian) assemblage comprises Iguanodon bernissartensis and Mantellisaurus atherfieldensis. Recent suggestions concerning the creation of additional new Wealden Group taxa reflect systemic misunderstandings of the actual skeletal material. A detailed taxonomic review of all Wealden Group iguanodontians is in preparation.

Resumo: Há um relativo depauperamento no tocante ao nosso conhecimento a respeito da relação entre a filosofia kantiana e a constituição da geografia moderna e, conseqüentemente, científica. Esta relação, quando abordada, o é - vezes sem conta - de modo oblíquo ou tangencial, isto é, ela resta quase que exclusivamente confinada ao ato de noticiar que Kant ofereceu, por aproximadamente quatro décadas, cursos de Geografia Física em Königsberg, ou que ele foi o primeiro filósofo a inserir esta disciplina na Universidade, antes mesmo da criação da cátedra de Geografia em Berlim, em 1820, por Karl Ritter. Não ultrapassar a pueril divulgação deste ato em si mesma só nos faz jogar uma cortina sobre a ausência de um discernimento maior acerca do tributo de Kant àfundamentação epistêmica da geografia moderna e científica. Abrir umafrincha nesta cortina denota, necessariamente, elucidar o papel e o lugardo “Curso de Geografia Física” no corpus da filosofia transcendental kantiana. Assim sendo, partimos da conjectura de que a “Geografia Física” continuamente se mostrou, a Kant, como um conhecimento portador de um desmedido sentido filosófico, já que ela lhe denotava a própria possibilidade de empiricização de sua filosofia. Logo, a Geografia Física seria, para Kant, o embasamento empírico de suas reflexões filosóficas, pois ela lhe comunicava a empiricidade da invenção do mundo; ela lhe outorgava a construção metafísica da “superfície da Terra”. Destarte, da mesma maneira que a Geografia, em sua superfície geral, conferiu uma espécie de atributo científico à validação do empírico da Modernidade (desde os idos do século XVI), a Geografia Física apresentou-se como o sustentáculo empírico da reflexão filosófica kantiana acerca da “metafísica da natureza” e da “metafísica do mundo”.THE COURSE OF PHYSICAL GEOGRAPHY OF IMMANUEL KANT(1724-1804): CONTRIBUTION FOR THE GEOGRAPHICALSCIENCE HISTORY AND EPISTEMOLOGYAbstract: There is a relative weakness about our knowledge concerningKant philosophy and the constitution of modern geography and,consequently, scientific geography. That relation, whenever studied,happens – several times – in an oblique or tangential way, what means thatit lies almost exclusively confined in the act of notifying that Kant offered,for approximately four decades, “Physical Geography” courses inKonigsberg, or that he was the first philosopher teaching the subject at anyCollege, even before the creation of Geography chair in Berlin, in 1820, byKarl Ritter. Not overcoming the early spread of that act itself only made usthrow a curtain over the absence of a major understanding about Kant’stribute to epistemic justification of modern and scientific geography. Toopen a breach in this curtain indicates, necessarily, to lighten the role andplace of Physical Geography Course inside Kantian transcendentalphilosophy. So, we began from the conjecture that Physical Geography hasalways shown, by Kant, as a knowledge carrier of an unmeasuredphilosophic sense, once it showed the possibility of empiricization of hisphilosophy. Therefore, a Physical Geography would be, for Kant, theempirics basis of his philosophic thoughts, because it communicates theempiria of the world invention; it has made him to build metaphysically the“Earth’s surface”. In the same way, Geography, in its general surface, hasgiven a particular tribute to the empiric validation of Modernity (since the16th century), Physical Geography introduced itself as an empiric basis toKantian philosophical reflection about “nature’s metaphysics” and the“world metaphysics” as well.Keywords: History and Epistemology of Geography, Physical Geography,Cosmology, Kantian Transcendental Philosophy, Nature.

The study of the propagation of "plastic" waves in solids has reached a stage where it is necessary to consider which direction future research should take. In the past 90 or so years many experiments, mostly designed to elucidate certain points of engineering significance, and a few attempts at a theoretical study have cast some light on the subject and revealed it as one of formidable difficulty.Nearly all the experiments have of necessity relied on rather dubious theories for their interpretation, and part of the present paper will be devoted to a description of an apparatus which gives results capable of being interpreted with a very minimum of theory. The remainder of the paper is devoted to a short review of past work with particular emphasis on basic phenomena and to a brief discussion on the most pressing problems still remaining. The experiments described in the present paper bring to light a factor in the propagation of "plastic" waves that seems to have been overlooked in previous work.

In recent years an increasing number of performances on the Baltic theatre stage attempt to escape the dominant understanding of “performing history” as a repetition or reinforcement of the monumental representations of the historical past or as a (re)production of “mythistory” (Joseph Mali). Lithuanian creators of performances about history increasingly choose hybrid approaches of representation, merging memorialization and critique, imagination and fact, documents and speculative inventions as forms of engagement with the past. This playful re-imagination of the historical past serves as a creative laboratory, where audience ability to recognize and/or resist historical manipulations as well as to embrace plural and polyphonic nature of memory are tested. In some cases, however, Lithuanian theatre creators are interested in “truthful” or “authentic” representations of personal memories, rather than a performative investigation ofmechanisms of production of the “reality effect” in historiography and their impact on audience perception. This article examines the ways in which historical events are represented on the contemporary Lithuanian theatre stage and, at the same time, addresses the larger issues around the implications of particular theatricalstagings of the past on the current understanding of the subject of history.

The Canons of Athanasius, a homiletic work written at the beginning of the fifth century in one of the cities of the Egyptian chora, provide us with many important and detailed pieces of information about the Church hierarchy. Information gleaned from this text can be found in studies devoted to the history of Christianity of the fourth and fifth centuries, but rarely are they the subject of reflection as an autonomous subject. To date, no one has endeavoured to determine how the author of the Canons sought to establish the parameters of his work: why he included certain things in this work, and why left other aspects out despite them being within the boundaries of the subject which he had wished to write upon. This article looks to explore two thematic areas: firstly, what we learn about the hierarchical Church from the Canons, and secondly, what we know about the hierarchical Church from period sources other than the Canons. This article presents new arguments which exclude the authorship of Athanasius and date the creation of the Canons to the first three decades of the fifth century.

The article deals with an instrumental use of the national legislation by the local authorities in Kharkiv, the second-largest city in Ukraine and shows how the shortcomings in the national legislation on the politics of memory can be used by the local political elites of “borderland city” in an attempt to raise the rating and/or to mobilize the electorate before the elections. Consequently, several interviews with local experts and activists were conducted in 2019, and qualitative data analysis was made for the transcribed texts as well as a short review of other papers on the subject. Also, the article shows how the local court can accelerate the process of depriving a historical building of the status of an architectural monument using decommunization laws. The study confirms the existence of serious polarization in Ukrainian society and the superficial nature of decommunization (started in 2015), which stimulates the deepening of such polarization.

This paper presents an experience report concerning the use of a platformcalled “Storium” in the subject of “Interactive Fiction” for undergraduatestudents, from a Digital Design Course. The objective was to use the learningtheories of constructivism and multimedia learning to create an instructionalplan devised to teach the students how to create complex interactive narrativesand stories from a practical perspective. During the course, the students learnedthe subject’s theoretical concepts and applied them directly, creating their owninteractive fiction. The results from this research proposes a new approach, usingdigital tools whose resources provides an environment for the creation ofinteractive narratives. These narratives can be used to aid future designs ofinstructional plans for complex writing concepts.

Sexual behavior in sleep has only recently been recognized as a variant of non–rapid-eye-movement (NREM) arousal parasomnias. This chapter discusses a case of sexsomnia precipitated by obstructive sleep apnea, the ensuing impact on the subject and his bed partner, and evaluation and management strategies. Sexsomnia is suspected to be highly underreported and carries significant physical, psychosocial, and forensic ramifications. Polysomnography with expanded electroencephalography can help identify concurrent sleep disorders and exclude other etiologies such as epilepsy. Treatment of comorbid sleep disorders such as obstructive sleep apnea and sleep deprivation is highly effective in controlling the abnormal sexual behavior. There is a pressing need for research and expansion of current understanding to develop a standardized approach to evaluation and management of sexsomnia.

Non-cisgender and non-straight identity language has long been a site of contention and evolution. There has been an increase in new non-cisgender, non-straight identity words since the creation of the internet, thanks to social media platforms like Tumblr. Tumblr in particular has been host to many conversations about identity and self-naming, though these conversations have not yet been the subject of much academic research. Through interviews and analysis of Tumblr posts, this thesis examines the emergence of new identity words, or neo-identities, used by non-cisgender and non-straight users of Tumblr. The work presents neo-identities as strategies for resisting and challenging cisheteronormative conceptions of gender and attraction, as well as sources of comfort and relief for non-cisgender/non-straight people who feel ‘broken’ and excluded from mainstream identity categories. This thesis also posits that Tumblr is uniquely suited for conversations about identity because of its potential for self-expression, community, and anonymity.

The purpose of research. The goal of this study is to analyze different domestic software packages intended for modeling of business processes involving queues and time parameters. The main analysis criteria are: the possibility of graphical development or conversion of the business process block diagram to the model; automatic generation of simulation model; quick and convenient construction of domain-specific application; the variety of result analysis tools. The relevance of the problems to choose the optimal modeling tool is determined by the need to use only domestic software for business process investigation in the military and some scientific organizations, and by the lack of information about existing software products. In this paper, the subject of study is the Russian simulation modeling environment GPSS Studio.Materials and methods. In this article, the analysis of the possibility of effective usage of GPSS Studio environment during business processes analysis and synthesis is performed. The study was performed on the available examples of different applications of this tool, and by the creation of the model analyzing business processes that are typical for any HR department.Results. Taking into account the performed analysis of functionality and practical applications of the GPSS Studio environment, the good prospects of its application for modeling of business processes involving queues and time parameters are shown. The further system improvements intended for effective business process modeling are proposed.Conclusion. As a result of the performed study, we can do the following conclusions and recommendations:– The GPSS Studio graphical editor can be successfully used for the graphical description of the business processes when it is required to analyze: queues, the load of resources, and the time characteristics of the processing,– The simulation model is automatically generated from the graphical description. The produced model can be finally debugged and verified with the GPSS Studio,– The standalone simulation application working in terms of the subject domain can be built from the simulation model using the simulation environment,– Using this application, it is possible to perform complex business process simulation modeling by means of varying system parameters and performing of singular experiments, a series of dedicated experiments, and optimizing experiments,– Since the GPSS Studio concepts include the possibility to create domain-specific libraries of standard blocks, it is possible to create a library of standard elements similar to IDEF, BPMN, DFD block charts to facilitate faster description and modeling of business processes. After the creation of such a library, there would be no need to manually write GPSS code, since the business process model could be built by a simple connection of standard blocks.
