We use polarimetric micro-Doppler for the detection of arm motion, especially for the classification of whether someone has their arms swinging and is thus unloaded. The arm is often bent at the elbow, providing a surface somewhat similar to a dihedral. This is distinct from the more planar surfaces of the body which allows us to isolate the signals of the arm (and knee). The dihedral produces a double bounce that can be seen in polarimetric radar data by measuring the phase difference between HH and VV. This measurement can then be used to determine whether the subject is unloaded.

AbstractThe present article is concerned with “the chapter of the description of the [four] categories of women”, the strībhedavarana-khaa, which comprises the stanzas 463–467 of the great romantic poem Padumāvatī. It was composed ca. 1540 A.D. by the Muslim poet Malik Muammad Jāyasī, the most significant representative of the ūfī poets of Oudh, in Old Avadhi, the language of his native country.This study opens with a general introduction about the author and his chef-d'œuvre, which also gives the contents of the epic. The subject dealt with here is introduced by a short synopsis on the tradition of the description of the four categories of women, i.e. padminī, citriī, śakhinī, and hastinī, in Sanskrit erotic literature. Text and translation of the strībhedavarana-khaa, together with exhaustive notes, form the greater part of this article. The notes which appear after the translation of each verse, aim mainly at comparing Jāyasī's conception of the four categories of women with those held by authors of Sanskrit texts on this subject. For purpose of comparison, more than ten Sanskrit texts, beginning with Kokkoka's Ratirahasya, which was composed before 1200 A.D., have been cited. Besides, various quotations both from Sanskrit literature and from Arabic narrative literature have been given as illustrative examples, particularly in those cases, where no parallels for specific details in Jāyasī's description could be found in the Sanskrit texts referred to.The comparison of Jāyasī's conception of the four categories of women with those held by Kokkoka and his epigones, points to the conclusion that probably Jāyasī has not used any definite literary source for writing this particular chapter, but rather has relied upon possibly wide-spread popular traditions of this system of classification of women.Two conspicuous peculiarities in Jāyasī's very detailed description which are worthy of special note, have been discussed at the conclusion of the introductory remarks. The first is the “confusion” of the termini sakhinī and sighinī, that has been imputed to the poet by several editors of his œuvre; from my point of view, however, this “confusion” was fully intended by the author. The second peculiarity is Jāyasī's apparently individual interpretation of the so-called “sixteen śgāras”, i.e. “methods of decoration of the body”, which combined with the “twelve ābharaas”, i.e. “ornaments”, are generally known as the complete ornamentation of woman. According to Jāyasī, the “sixteen śgāras” are the “sixteen physical refinements”, divided into four groups: (1) four parts of the body (in the widest sense of the word) having “longness”, i.e. hair, fingers, eyes, neck, (2) four having “shortness”, i.e. teeth, breasts, forehead, navel, (3) four having “broadness”, i.e. cheeks, buttocks, arms, calves, and (4) four having “slenderness”, i.e. nose, waist, belly, lips.

AbstractA new hydrometeor classification algorithm that combines thermodynamic output from the Rapid Update Cycle (RUC) model with polarimetric radar observations is introduced. The algorithm improves upon existing classification techniques that rely solely on polarimetric radar observations by using thermodynamic information to help to diagnose microphysical processes (such as melting or refreezing) that might occur aloft. This added information is especially important for transitional weather events for which past studies have shown radar-only techniques to be deficient. The algorithm first uses vertical profiles of wet-bulb temperature derived from the RUC model output to provide a background precipitation classification type. According to a set of empirical rules, polarimetric radar data are then used to refine precipitation-type categories when the observations are found to be inconsistent with the background classification. Using data from the polarimetric KOUN Weather Surveillance Radar-1988 Doppler (WSR-88D) located in Norman, Oklahoma, the algorithm is tested on a transitional winter-storm event that produced a combination of rain, freezing rain, ice pellets, and snow as it passed over central Oklahoma on 30 November 2006. Examples are presented in which the presence of a radar bright band (suggesting an elevated warm layer) is observed immediately above a background classification of dry snow (suggesting the absence of an elevated warm layer in the model output). Overall, the results demonstrate the potential benefits of combining polarimetric radar data with thermodynamic information from numerical models, with model output providing widespread coverage and polarimetric radar data providing an observation-based modification of the derived precipitation type at closer ranges.

Tools to identify and classify stratiform and convective rains at various times of the 12 days from June 2015 to March 2016 in Jincheon, Korea, were developed by using a Parsivel disdrometer and S-band polarimetric (S-POL) radar data. Stratiform and convective rains were identified using three different methods (vertical profile of reflectivity (VPR), the method proposed by Bringi et al. (BR03), and a combination of the two (BR03-VPR)) by using a Parsivel disdrometer for its applications to radar as a reference. BR03-VPR exhibits a better classification scheme than the VPR and BR03 methods. The rain types were compared using the drop size distribution (DSD) retrieved from polarimetric variables and reflectivity only. By using the DSD variables, a new convective/stratiform classification line of the log-normalized droplet number concentration ( log 10 N w ) − median volume diameter ( D 0 ) was derived for this area to classify the rainfall types using DSD variables retrieved from the polarimetric radar. For the radar variables, the method by Steiner et al. (SHY95) was found to be the best method, with 0.00% misclassification of the stratiform rains. For the convective rains, the DSD retrieval method performed better. However, for both stratiform and convective rains, the fuzzy method performed better than the SHY95 and DSD retrieval methods.

The author poses the problem of the status of sociology of the body as an independent sub-discipline, putting forward the hypothesis that today this moniker only unites the spectrum of those sociological directions that are engaged in the study of separate theoretical and applied issues related to corporeality. This review allows for securing the trend towards fragmenting sociology of the body as a field of study and strengthening its status as a rubric for research, rather than a full-fledged area of sociology. In order to clarify the subject of sociology of the body and its correlation with other disciplines which study embodiment, three classifications of theories used in body studies are analyzed — philosophical, anthropological and sociological. Unlike other researchers, the author of this article considers the opposition of structuralism and interpretativism to be the most appropriate for designating opposing research programs in the sociological classification of body theories.

In this article, the reflections of the problem "homelessness" in the field of art will be examined through three different art works created by Andres Serrano within the framework of the subject. The artist focuses on the problem of homelessness in the state of New York, United States, in his art series titled "Nomads” (1990), "Sign of the Times (2013) and “Residents of New York” (2014). Human body is the smallest unit that forms the social structure. It’s effects of its situation between the dilemma of existence and absence in social and psychological areas, will be covered through the dialogues held with the participants that took place in the artist's project. The coding and positioning of the body within the framework of the definition and classification of homeless / homelessness will be mentioned. Besides, the process of transforming the problem into an art work in a creative way will be evaluated. Keywords: Andres Serrano, homeless, homelesness, body, “Nomads”, “Sign of the Times”, “Residents of New York”

IntroductionBy the present, the study of corporeality as a psychological phenomenon in schizophrenia has had a lack of attention. At the focus of works, there have been mainly psychopathological phenomena: cenestopathies, visceral hallucinations and body scheme disturbances. There is an evidence of the necessity for psychological investigations: the execution of radical changes in appearance, a frequent turning to plastic surgery, dysfunctional wearing and transsexuality.ObjectivesThe experimental group consisted of 23 patients in schizophrenia of paranoid type (F 20.00). The control group consisted of 27 healthy subjects.AimIt is to study the peculiarity of experiencing their own body by patients in schizophrenia.MethodsThere are projective techniques, such as: “A Picture of Me”, “Verbal Self-Portrait”, ‘A Picture of Inner Body” and the psychosemantic test “Classification of Sensations”.ResultsThere are statistically significant differences (P < 0.005) found between the groups:– patients with schizophrenia are characterized for their deficit of experiencing their body. It does not refer to “Myself” and is deinvidualized. The body does not serve as a physical presentation of the subject in a social world;– a wary attitude is observed in relation to body displays in the form of inner body sensations with a minor (than in norm) awareness relatively to the inner arrangement of their own body. This causes the increase of the quantity of intraceptive sensations categorized by patients in schizophrenia as unhealthy or a threat.ConclusionThe above-mentioned peculiar features of corporeality in schizophrenia make it a source of negative experiences.Disclosure of interestThe authors have not supplied their declaration of competing interest.

The article examines the place of Charles Ballyʼs paper «Syntaxe de la modalité explicite» in the body of work of the prominent Swiss linguist on the category of modality and identifies the role of his ideas in modern description of syntax. In Charles Ballyʼs linguistic heritage the concept of modality plays an exceptionally important role. His views o n the modal organization of the sentence are based on the theoretical perspective to describing the phenomenon of language proposed by his teacher Ferdinand de Saussure. Charles Ballyʼs theory of modality is an integral part of his general theory of enunciation. Identification of the two components in the semantic structure of the sentence, namely the modus and the dictum, becomes some kind of a bridge between Saussureʼs intellectualized grammar of language and the grammar of speech, which specifically entails the study of emotional and affective factors, and also stylistic aspects of human language. According to Charles Bally, the modus is a combination of a modal verb, which may contain a variety of shades of opinion, feeling or will, and a modal subject, which can represent a speaking subject and also other subjects. Charles Ballyʼs studies significantly influenced the interpretation of the category of modality in modern linguistics. However, not every theory based on the idea of identifying the modus and the dictum in the sentence can be theoretically convincing. Identifying the dictum with the representation of the objective, and the modus with the subjective led to unsubstantiated theoretical opposition of objective and subjective modality. Only misunderstanding of Charles Ballyʼs ideas might explain the attempts to attribute the ability to express the category of evaluation and emotionality to the modus. Charles Ballyʼs original theoretical views proved to be productive in the development of the cognitive theory of modality, which in its turn is based on other theoretical views on the phenomenon of language. Within this theory, modality is defined as a category that describes the mental-sensory differentiation of the speakerʼs thoughts in the process of sentence formation. According to the active approach to sentence interpretation, the subject of the modus in cognitive modality theory is only the speaker. The paper «Syntaxe de la modalité explicite», which Charles Bally described as a program of studies, has not lost its relevance. The task of describing the semantic shades of modality, as well as various forms of its expression, the principles of classification of modal verbs outlined in the paper as the goal of linguistics, remains largely unresolved today.

ABSTRACT Objectives: to construct and validate an instrument for assessing the functionality of individuals with schistosomiasis. Methods: methodological study, developed in three stages: 1) construction of the instrument and its association with categories of the International Classification of Functionality, which the study used to elaborate the questions; 2) validation of content, performed by judges experts in the subject; 3) application of the instrument by the test-retest technique in the population with schistosomiasis in 14 days. The study used the correlation coefficient kappa to calculate the degree of agreement between the judges kappa. Results: in its final version, the instrument consists of 27 items, 9 of which are from the Body functions component, 6 from Body structures, 4 from Activity and participation, and 8 from Environmental factors. Conclusions: the constructed instrument has a biopsychosocial approach, considering four components of the ICF, besides presenting good validity and interobserver reliability.

This article explores the diversity of British literary responses to Diaghilev's project, emphasising the way in which the subject matter and methodologies of Diaghilev's modernism were sometimes unexpectedly echoed in expressions of contemporary British writing. These discussions emerge both in writing about Diaghilev's work, and, more discretely, when references to the Russian Ballet find their way into the creative writing of the period, serving to anchor the texts in a particular cultural milieu or to suggest contemporary aesthetic problems in the domain of literary aesthetics developing in the period. Figures from disparate fields, including literature, music and the visual arts, brought to their criticism of the Ballets Russes their individual perspectives on its aesthetics, helping to consolidate the sense of its importance in contributing to the inter-disciplinary flavour of modernism across the arts. In the field of literature, not only did British writers evaluate the Ballets Russes in terms of their own poetics, their relationship to experimentation in the novel and in drama, they developed an increasing sense of the company's place in dance history, its choreographic innovations offering material for wider discussions, opening up the potential for literary modernism's interest in impersonality and in the ‘unsayable’, discussions of the body, primitivism and gender.
