The 19Th Century

In the International Headache Society classification of headaches, the concept of aura is given a key role. It serves as a boundary between ‘migraine without aura’ and ‘migraine with aura’. Historically, the concept of an aura was borrowed from the epilepsy vocabulary; a borrowing that took place in English medicine at the beginning of the 19th century and in French medicine in the mid-19th century. It would therefore be interesting to see which features of the epileptic aura are used to explain the migraine aura. Based on the French and English medical literature of the 19th century, two processes have been reviewed: (i) the emergence of the concept of aura, and (ii) the modifications of this concept throughout the 19th century. It appears that the original medical use of the term ‘aura’ as a set of rising tactile sensations was in use from the 2nd century until late in the 19th century, but then various other symptoms were recognized and the aura gradually became accepted as an early part of the seizure. By the end of the 19th century the aura that preceded a migraine was seen as a similar process, and thought of as part of the migraine sequence.

Abstract. High-quality research developed during the 19th century established the foundations of rock strain investigations. Careful observation and description of rock fabrics and deformed objects in rocks allowed early researchers to obtain mathematical expressions that are still used today to quantify strain. Thus, in a span of a few decades, and applying basic scientific methodology, these researchers developed the concept of the strain ellipsoid, defined mathematically the difference between constant-volume and volume-loss deformation, constructed the basic equations that define pure and simple shear deformation, and discovered the mechanism of pressure–solution deformation. These advances were fundamental to seminal works on strain analysis and deformation fabrics in the mid-20th century. However, they are rarely addressed in modern studies, which suggests a lack of awareness among current researchers. In order to bring attention to these landmarks of strain research, I provide a historical review of the high standards of analysis that led to the definition of the fundamental equations and concepts on strain during the 19th century.

Difference is a social construction, and as such it needs a discourse to produce meaning and be socially effective. As a discourse is always socially and historically grounded, so it is the meaning of difference. This article proposes that the difference in the contemporary world is dominantly articulated in the discourse of diversity, as the discourse of exoticism was the dominant discourse of difference in the 19th Century. This proposal will be proved as I show that, as diversity becomes the appreciated discourse in the present, the exoticism loses its value. Stating that, I will try to understand the conditions of existence of each discourse. I will argue that the exoticism was founded in the 19th century upon three fundaments: imperialism, the idea of progress and nation. They provided the condition for a discourse that based the production of difference on the stable separation of an internal and an external space. After examining the fundaments and their relations with the discourse of exoticism, I will show that the production of difference is no longer based on stable notions of internal and external spaces. Currently, difference is produced on the basis of fragmented and globalized social relations, which requires a discourse flexible enough to cope with these material conditions. The discourse of diversity is this discourse.

The diagnostic criteria issued by the International Headache Society (IHS) (1988) and those of the World Federation of Neurology (WFN) (1969) were evaluated vis-à-vis 163 consecutive cases of cluster headache diagnosed according to the criteria of Ekbom (1970). The agreement between the IHS and Ekbom criteria was very good (96.9%). The difference was explained by five patients who all lacked local autonomous symptoms and signs (conjunctival injection, lacrimation, etc.). At least one of these signs is mandatory according to the IHS and thus the patients escaped a definite diagnosis. Agreement between the WFN and Ekbom criteria was 84.0% ( n= 163) and between the WFN and IHS criteria only 76.0% ( n= 158).

The taxonomy and classification of the microcanthid fish genus Microcanthus Swainson has been a subject of contention dating back to the 19th century. Its allopatric, disjunct anti-equatorial distribution across the Indo-West Pacific has resulted in the recognition of several nominal taxa, though these have been widely regarded as synonyms of Microcanthus strigatus (Cuvier). Following the results published in a companion study elsewhere by the authors, the taxonomy of Microcanthus and the validity of these nominal synonyms are herewith revised. Microcanthus strigatus is redescribed on the basis of 66 specimens from East Asia, Hawaii and Western Australia, and M. joyceae is resurrected and redescribed on the basis of 25 specimens from eastern Australia and the southwest Pacific. Microcanthus differs from other microcanthid genera in having the following combination of characters: dorsal-fin rays XI,15–17 (usually XI,16); anal-fin rays III,13–15 (usually III,14); pectoral-fin rays 15–17 (usually 16); scales ctenoid with ctenial bases present; lateral-line scales partially or heavily obscured by adjacent scales; and body pale in preservation with five horizontal dark stripes reaching the posterior edges of dorsal and anal fins, and base of caudal fin. The review is accompanied by a key to the genera of Microcanthidae.

Paroxysmal Positional Vertigo

Migraine and vertigo are common disorders in medicine, affecting about 14–16% and 7–10%, respectively, of the general population. Recent epidemiologic studies indicate that 3.2% of the population have both migraine and vertigo. Vertigo may occur in up to 25% of patients with migraine. Migraine is the most frequent vascular disorder causing vertigo in all age groups. Migraine leads to various central or peripheral vestibular syndromes with vertigo such as migrainous vertigo, basilar-type migraine, benign paroxysmal vertigo of childhood, and other vertigo syndromes related to migraine. Migrainous vertigo is the most common cause of spontaneous recurrent vertigo. Diagnostic criteria for migrainous vertigo have been proposed but are not included in the most recent International Headache Society classification of migraine. On the other hand, there are statistical associations between migraine and vertigo syndromes including benign paroxysmal positional vertigo, Meniere's disease, persistent cerebellar symptoms, anxiety-related dizziness, and motion sickness. Vertigo can also act as a migraine trigger. Although some mutations in the CACNA1A gene have been identified in some familial cases, the mechanism of migraine-associated vertigo is still obscure. Treatment includes vestibular suppressants for acute attacks and migraine prophylaxis for patients with frequent attacks.

Grammatical Tradition

Summary French philosophical grammmar and grammatical rationalism developed from the 17th-century Port Royal Grammar, but they were not adopted by Spanish grammarians until early in the 19th century. Of works responsible for the introduction of French grammatical philosophy in Spain, one of the earliest and the most important one is the Principios de gramática general (Madrid 1835), by José Gómez Hermosilla (1771–1837/38?). The work was very well received; by 1841 it already was into a third edition. Even before first appearing in print, a manuscript of the Gramática General was used to adapt Gómez Hermosilla’s ideas to the 1828 Castilian grammar of Jacobo Saqueniza (anagram for Joaquín Cabezas). The most important of the Castilian grammars influenced by the work of Gómez Hermosilla were the one just mentioned and the one by Antonio Martinez de Noboa, published in 1839. The application of Hermosilla’s theories to descriptive grammars of Castilian required adapting both the theory and the description to achieve a reasonable fit between universal and language specific aspects. Other adjustments were required of the writers of descriptive grammars in order to avoid conflicts with a long and well established grammatical tradition. Nevertheless, grammars like those of Saqueniza and Noboa show innovations which resulted from their relationship with the theories of Hermosilla which will produce a deictic interpretation of articles, possesives and demonstratives, and will affect the theory of verb tenses, as well as the definitions of prepositions and conjunctions, and the classification of sentences. Additionally, Noboa’s Castilian Gramática, whose title makes a claim to be in accordance with grammatical philosophy, includes the most extensive and systematic treatment of syntax prior to the appearance of the work of Andres Bello (1781–1865) in 1847.

History of term ‘phobia’The term ‘phobia’ derives from the Greek word ‘phobos’ meaning panic-fear and terror, and from the deity of the same name who provoked fear and panic in one's enemies. Although morbid fears have been described by doctors from Hippocrates onwards, the word phobia has only been used on its own since the beginning of the 19th century, and it gradually gained acceptance during that century in the same sense as today, viz. an intense fear which is out of proportion to the apparent stimulus. Such fear cannot be explained or reasoned away and leads to avoidance of the feared situation where possible.

The article is devoted to the work of A. Bely in the development of Russian culture in the late 19th - early 20th centuries. Attention is paid to the motives of the creative path of the philosopher-poet, who created the basis of Russian symbolism. By analyzing the cultural and historical manifestations of the second half of the 19th century and the first half of the 20th century, reflection in the works of art and science workers, an assessment of the severity of symbolism for the development of Russian philosophy and the field of art in general. In the process of the formation of symbolism in Bely's work, neo-Kantian motives are clearly revealed in the formulation of the problem of the difference between subjective perception and the essence of the object of perception in itself, that is, distinguishing between the symbol and the signified. By comparing Bely's views with the concept of sophiology and anthroposophy, distinct Kantian positions of the philosopher-poet stand out. These include the schematism of space and time, an attempt to apply the categories of natural science to the field of philosophy of art, as well as the demarcation of the immanent and the transcendent. Despite the fact that the ideas of the philosopher-poet in their form have similar positions with the anthroposophy of R. Steiner and with the ideas of V. Solovyov, however, the key content is the neo-Kantian methodology of "critical deepening" of thought and its rationalization. The actualization of Bely's creativity and the issue of his neo-Kantian motives is carried out by attracting research from related branches of knowledge on the principles of interdisciplinary consideration and implementation of an integrated approach.

The aim of this paper is providing the analysis of the classification of invalid transactions into void and voidable, which is recognized in many countries. This classification takes roots from the times of Ancient Rome, and was further developed in the 19th century thanks to the works of pandectists, primarily F.K. von Savigny and B. Windscheid. Today many European states are reforming their civil legislation. This fact allows us to take a fresh look at many institutions of civil law. In addition to the traditional approaches that are characteristic of the countries of the pandecto system, special attention should be paid to the “theorie moderne”, which is widespread in the countries of the Romanesque legal system. In the context of the invalidity of transactions, the article analyzes the provisions of the legislation of the leading European countries – Germany, France, the Netherlands, Italy, Spain, Belgium. Based on the above, it is concluded that this classification of the invalidity of transactions has not lost its meaning and is relevant today.

Vital Element

By the dawn of the twentieth century, a guidebook was a vital element of a tourist’s packing list and an item, which a tourist could not do without.  The guidebook not only provided practical and useful information, but also advised the tourist about what ‘ought to be seen’. It accompanied the development and maturation of modern tourism and witnessed an explosion in the second half of the 19th century and after. The guidebook was gradually improved, highly commercialized, popularized, and extended to many parts of the world and somehow managed to impose ‘beaten tracks’ on tourists. Similarly, the guidebook accompanied European colonial schemes, served as a tool for them and reflected their agendas and the mindset of the age. This paper is based on a large number of French and English guidebooks spanning approximately the period  between the mid-nineteenth and early twentieth centuries and addresses the following questions: when and how was North Africa included in the tourist guidebook literature? What visions did the guidebook provide of the region? How far did the guidebooks contribute to placing North Africa in the global tourist networks and with what effect?
