Российское государство начало придавать все большее значение правовым обычаям, существующим среди различных этнических групп с начала 19-го века, признавая право народов, включенных в орбиту российской государственности, самим управлять собственной повседневностью в соответствии с традиционными моральными нормами и правовыми обычаями. В Венгрии эта практика и значение этих исследований были подробно рассмотрены выдающимся исследователем обычного права Карой Тагани. Выводы исследований правового обычая на Кавказе с участием Вс. Ф. Миллера в 1878 г. также способствовали изучению народного права яссов в Венгрии. Богатое исследовательское наследие Вс. Миллера получило дальнейшее изучение в трудах наиболее выдающихся венгерских историков. На основании данных исследований, проведенных в период 1939-1948 гг., были также установлены новые направления исследований. Целью исторических, архивных и этнографических исследований последних десятилетий и исследований, проведенных членами Эрнё Таркань-Сюч (Правовой культурно-исторической и правовой этнографической исследовательской группы), была система общественных норм, регулирующих повседневную жизнь венгерских ясов. Наши нынешние представления о местном ясском сообществе (включая администрацию, экономику и семейную жизнь), правила его сосуществования, моральные нормы, наказания и применяемые неформальные санкции в настоящее время уже сравнительно более обстоятельно изучены и дифференцированы. Также совершенно очевидно, что чувство свободы, существующее в автономном местном ясском сообществе, является существенным элементом социальной самоорганизации. Безусловно, одним из факторов данного социально-психологического феномена можно считать живучесть традиционной системы обычного права, в рамках которой сознание ясских общин на протяжении столетий формировалось и существовало, сохраняя свою самобытную идентичность. The Russian state began to attach more and more importance to the legal customs that have existed among various ethnic groups since the beginning of the XIXth century, recognizing the right of peoples included in the orbit of Russian statehood to manage their own daily lives in accordance with traditional moral norms and legal practices. In Hungary, this practice and the significance of these studies have been examined in detail by the outstanding customary law researcher Kara Tagani. Conclusions of studies of legal custom in the Caucasus with the participation of Vs. F. Miller in 1878 also contributed to the study of the customary law of the Jász in Hungary. Miller’s rich research heritage received further study in the writings of the most prominent Hungarian historians. New research areas were also established based on the data from the studies conducted in the period 1939-1948. The aim of the historical, archival and ethnographic studies of the recent decades and the studies conducted by members of Ernø Tarkany-Sych (Legal Cultural-Historical and Legal Ethnographic Research Group) was a system of social norms that regulate the daily life of Hungarian Jász people. Our current ideas about the local Jász community (including administration, economy and family life), the rules of its coexistence, moral standards, punishments and the applied informal sanctions are now comparatively more thoroughly studied and differentiated. It is also obvious that the sense of freedom that exists in the autonomous local Jassy community is an essential element of social self-organization. One of the factors of this socio-psychological phenomenon can be considered the survivability of the traditional system of customary law, within which the consciousness of the Jassy communities has been formed and existed over the centuries, preserving its original identity.

Unmanned aerial vehicles (UAVs) represent a new model of social robots for home care of dependent persons. In this regard, this article introduces a study on people’s feeling of safety and comfort while watching the monitoring trajectory of a quadrotor dedicated to determining their condition. Three main parameters are evaluated: the relative monitoring altitude, the monitoring velocity and the shape of the monitoring path around the person (ellipsoidal or circular). For this purpose, a new trajectory generator based on a state machine, which is successfully implemented and simulated in MATLAB/Simulink®, is described. The study is carried out with 37 participants using a virtual reality (VR) platform based on two modules, UAV simulator and VR Visualiser, both communicating through the MQTT protocol. The participants’ preferences have been a high relative monitoring altitude, a high monitoring velocity and a circular path. These choices are a starting point for the design of trustworthy socially assistive UAVs flying in real homes.

For an unmanned aerial vehicle, in order to study the aerodynamic characteristics of the large aspect ratio wing during the deployment process with variable sweep angles, the scaled model was tested in the wind tunnel at different angles of attack with various sweep angles of wing. Experimental results indicate that the aerodynamic configuration satisfies the cruise design requirements, providing favorable longitudinal and lateral-directional stability. Fuselage of multi-plane combination brings beneficial effect for lift. Analysis have been made on the cases including wing flow separation which lead to the step of lift curve, and the existence of longitudinal unstable range during wing unfolding, which make the foundation for next optimum of configuration. The work described in this paper can be applied in the design of unmanned aerial vehicles, missiles and other research areas.

Abstract In the past few years the use of unmanned aerial vehicles in Lithuania has significantly increased. However, enjoying the advantages of this technology, which improves society’s socio-economical safety (public safety in a broad sense), raises some privacy concerns. This article analyses European Union and national legal regulations regarding the use of unmanned aerial vehicles as well as legal tools for defence of the right to privacy or prevention from its breaches in the Republic of Lithuania. Unmanned aerial vehicles have become popular only recently; thus, legislation regarding their use has not yet become a common topic among lawyers. Furthermore, case law of the Republic of Lithuania is silent about it. Thus, the authors model a situation of breach of privacy using an unmanned aerial vehicle and analyse possible defence mechanisms.

<abstract> <p>Over time, the use of UAVs (unmanned aerial vehicles)/drones has increased across several civil and military application domains. Such domains include real-time monitoring, remote sensing, wireless coverage in disaster areas, search and rescue, product delivery, surveillance, security, agriculture, civil infrastructure inspection, and the like. This rapid growth is opening doors to numerous opportunities and conveniences in everyday life. On the other hand, security and privacy concerns for unmanned aerial vehicles/drones are progressively increasing. With limited standardization and regulation of unmanned aerial vehicles/drones, security and privacy concerns are growing. This paper presents a brief analysis of unmanned aerial vehicle's/drones security and privacy-related concerns. The paper also presents countermeasures and recommendations to address such concerns. While laying out a brief survey of unmanned aerial vehicles/drones, the paper also provides readers with up-to-date information on existing regulations, classification, architecture, and communication methods. It also discusses application areas, vulnerabilities, existing countermeasures against different attacks, and related limitations. In the end, the paper concludes with a discussion on open research areas and recommendations on how the security and privacy of unmanned aerial vehicles can be improved.</p> </abstract>

Until now, there has been little experimental work investigating the processing and formal properties of the singular they suite of pronouns. As scientific and popular attention to singular they increases, it will be critical for research to acknowledge theoretical and ethical issues regarding discussion of this phenomenon. This commentary uses the recent paper by Doherty &amp; Conklin (2017) as a starting point to discuss issues surrounding work on the various forms of singular they. It concludes that there is sufficient theoretical and empirical evidence to claim they has a grammatically singular form (at least in colloquial English). It also recommends care be taken in academic discussions of the grammaticality and acceptability of terms which are associated with marginalised communities.

UNSTRUCTURED Over half of Americans report looking up health-related questions on the internet, including questions regarding their own ailments. The internet, in its vastness of information, provides a platform for patients to understand how to seek help and understand their condition. In most cases, this search for knowledge serves as a starting point to gather evidence that leads to a doctor’s appointment. However, in some cases, the person looking for information ends up tangled in an information web that perpetuates anxiety and further searches, without leading to a doctor’s appointment. The Internet can provide helpful and useful information; however, it can also be a tool for self-misdiagnosis. Said person craves the instant gratification the Internet provides when ‘googling’ – something one does not receive when having to wait for a doctor’s appointment or test results. Nevertheless, the Internet gives that instant response we demand in those moments of desperation. Cyberchondria, a term that has entered the medical lexicon in the 21st century after the advent of the internet, refers to the unfounded escalation of people’s concerns about their symptomatology based on search results and literature online. ‘Cyberchondriacs’ experience mistrust of medical experts, compulsion, reassurance seeking, and excessiveness. Their excessive online research about health can also be associated with unnecessary medical expenses, which primarily arise from anxiety, increased psychological distress, and worry. This vicious cycle of searching information and trying to explain current ailments derives into a quest for associating symptoms to diseases and further experiencing the other symptoms of said disease. This psychiatric disorder, known as somatization, was first introduced to the DSM-III in the 1980s. Somatization is a psycho-biological disorder where physical symptoms occur without any palpable organic cause. It is a disorder that has been renamed, discounted, and misdiagnosed from the beginning of the DSMs. Somatization triggers span many mental, emotional, and cultural aspects of human life. Our environment and social experiences can lay the blueprint for disorders to develop over time; an idea that is widely accepted for underlying psychiatric disorders such as depression and anxiety. The research is going in the right direction by exploring brain regions but needs to be expanded on from a sociocultural perspective. In this work, we explore the relationship between somatization disorder and the condition known as cyberchondria. First, we provide a background on each of the disorders, including their history and psychological perspective. Second, we proceed to explain the relationship between the two disorders, followed by a discussion on how this relationship has been studied in the scientific literature. Thirdly, we explain the problem that the relationship between these two disorders creates in society. Lastly, we propose a set of intervention aids and helpful resource prototypes that aim at resolving the problem. The proposed solutions ranged from a site-specific clinic teaching about cyberchondria to a digital design-coded chrome extension available to the public.


Over roughly the last decade, there has been a notable rise in new research on historical German syntax in a generative perspective. This volume presents a state-of-the-art survey of this thriving new line of research by leading scholars in the field, combining it with new insights into the syntax of historical German. It is the first comprehensive and concise generative historical syntax of German covering numerous central aspects of clause structure and word order, tracing them throughout various historical stages. Each chapter combines a solid empirical basis and valid descriptive generalizations with reference also to the more traditional topological model of the German clause with a detailed discussion of theoretical analyses couched in the generative framework. The volume is divided into three parts according to the main parts of the clause: the left periphery dealing with verbal placement and the filling of the prefield (verb second, verb first, verb third orders) as well as adverbial connectives; the middle field including discussion of pronominal syntax, order of full NPs and the history of negation; and the right periphery with chapters on basic word order (OV/VO), prosodic and information-structural factors, and the verbal complex including the development of periphrastic verb forms and the phenomena of IPP (infinitivus pro participio) and ACI (accusativus cum infinitivo). This book thus provides a convenient overview of current research on the major issues concerning historical German clause structure both for scholars interested in more traditional description and for those interested in formal accounts of diachronic syntax.

This article examines the first decades of the field of ethnohistory as it developed in the United States. It participated in the general rapprochement between history and anthropology of mid-twentieth-century social science. However, unlike parallel developments in Europe and in other research areas, ethnohistory specifically arose out of the study of American Indian communities in the era of the Indian Claims Commission. Thus ethnohistory developed from a pragmatic rather than a theoretical orientation, with practitioners testifying both in favor of and against claims. Methodology was flexible, with both documentary sources and ethnographic methods employed to the degree that each was feasible. One way that ethnohistory was innovative was the degree to which women played prominent roles in its development. By the end of the first decade, the field was becoming broader and more willing to engage both theoretical and ethical issues raised by the foundational work. In particular, the geographic scope began to reach well beyond North America, especially to Latin America, where archival resources and the opportunities for ethnographic research were plentiful, but also to areas such as Melanesia, where recent European contact allowed researchers to observe the early postcontact period directly and to address the associated theoretical questions with greater authority. Ethnohistory is thus an important example of a field of study that grew organically without an overarching figure or conscious plan but that nevertheless came to engage central issues in cultural and historical analysis.
