Abstract. To date there has been relatively little research within the domain of metamemory that examines how individuals monitor their performance during memory tests, and whether the outcome of such monitoring informs subsequent memory predictions for novel items. In the current study, we sought to determine whether spontaneous monitoring of test performance can in fact help individuals better appreciate their memory abilities, and in turn shape future judgments of learning (JOLs). Specifically, in two experiments we examined recognition memory for visual images across three study-test cycles, each of which contained novel images. We found that across cycles, participants’ JOLs did in fact increase, reflecting metacognitive sensitivity to near-perfect levels of recognition memory performance. This finding suggests that individuals can and do monitor their test performance in the absence of explicit feedback, and further underscores the important role that test experience can play in shaping metacognitive evaluations of learning and remembering.

Abstract. When two dot arrays are briefly presented, separated by a short interval of time, visual short-term memory of the first array is disrupted if the interval between arrays is shorter than 1300-1500 ms ( Brockmole, Wang, & Irwin, 2002 ). Here we investigated whether such a time window was triggered by the necessity to integrate arrays. Using a probe task we removed the need for integration but retained the requirement to represent the images. We found that a long time window was needed for performance to reach asymptote even when integration across images was not required. Furthermore, such window was lengthened if subjects had to remember the locations of the second array, but not if they only conducted a visual search among it. We suggest that a temporal window is required for consolidation of the first array, which is vulnerable to disruption by subsequent images that also need to be memorized.

AbstractAlthough visual culture of the 21th century increasingly focuses on representation of death and dying, contemporary discourses still lack a language of death adequate to the event shown by pictures and visual images from an outside point of view. Following this observation, this article suggests a re-reading of 20th century author Elias Canetti. His lifelong notes have been edited and published posthumously for the first time in 2014. Thanks to this edition Canetti's short texts and aphorisms can be focused as a textual laboratory in which he tries to model a language of death on experimental practices of natural sciences. The miniature series of experiments address the problem of death, not representable in discourses of cultural studies, system theory or history of knowledge, and in doing so, Canetti creates liminal texts at the margins of western concepts of (human) life, science and established textual form.

The analysis of the diagnostic informativeness of modern radiodiagnosticis methods in determining metastatic lymph node of pelvic cancer gynecological organs according to domestic and foreign publications. At the present stage methods of obtaining visual images pelvic lymph nodes are radiodiagnostics technologies (radiological, ultrasound, magnetic resonance tomography, scintigraphic). The analysis has shown that the researches devoted to diagnostic informational content of modern methods of radiodiagnosis in a differentiation of nature of damage of pelvic lymph nodes aren't enough. According to the literature, the most rational and perspective method for radiodiagnosis metastatics lymph node is a magnetic resonance imaging due to the high information content and thus specificity. At the same time, the continued relevance of further study of methods of radiodiagnostics in order to find the optimal one for the assessment of pelvic lymph nodes.

Most visuals in media stories either complement or are complemented by captions that accompany them. This study sought to establish the complementary and clarifying effect of captions that go with road carnage images in The Herald newspaper, a local daily published in Zimbabwe. A study was carried out which involved an interview with photo-journalists from the stable and an analysis of three visual images chosen from the publication. It was established that even as a visual, image can stand alone (but not always); it can tell 95 per cent of the story but will only be complete with an accompanying caption. It was also established that captions need not tell the obvious, but provide that which the picture will be lacking to complete the road carnage story. Captions, therefore, help complete the story as regards the when, where, how, who and what of the depiction. The visual image and the caption combine to complete a communication activity as the verbal and non-verbal form of languages. The study recommends that captions should be edited not only by photo-editors and journalists, but also by practising language people.

The book was compiled on the materials of the scientific conference “Anthropomorphic and zoomorphic representations of nations and states in the Slavic cultural discourse” (2019), held at the Institute of Slavic Studies of the Russian Academy of Sciences (Moscow) and devoted to the history of the nations’ personifications and generalized ethnic images in period of “imagined communities” formation. This process is reconstructing on verbal and visual sources and by methods of various disciplines. The historical evolution of such zoomorphic incarnations of nations as an Eagle (in the Polish patriotic poetry of the first third of the 19th cent), a Falcon (in the South Slavic and Czech cultures in the 19th cent), a Griffin (during the formation of the Cassubian ethnocultural identity) is considered. The animalistic national representations in the Estonian caricature of the interwar twenty years of the 20th cent., so as the functioning of the Bear’s allegory as a symbol of Russia in modern Russian souvenir products are analyzed. The originality of zoomorphic symbolism in Polish and Soviet cultures is shown оn the examples of para- and metaheraldic images in XXth cent. The transformation of the verbal and visual images of “Mother Russia” personifications in Russian Empire was reconstructed. The evolution of various allegories of ethnic “Self” and “Others” is presented by caricatures of 19th – 20th cent. in Slovenian periodic and in Russian “Satyricon” journal (1914–1918).

The article is devoted to the functions of intermediality in the symbolist novels by D. S. Merezhkovsky (Christ and the Antichrist trilogy). Intermediality is considered as a constructive and structural basis of the novels and the principle of poetics.Visual images of art reflect the writer’s theurgical aesthetics and his conceptual religious-philosophical ideas. They are the basis of the mysteriological-mythological plot and perform functions of the symbolic “crossing” of various religions and cultures borders. The article concludes that intermediality in the structure of the symbolist novel creates media myth about sacred function of the art as a meta-text.

Abstract Objective The most common histopathologic malignant and benign nodules are Adenocarcinoma and Granuloma, respectively, which have different standards of care. In this paper, we propose an automatic framework for the diagnosis of the Adenocarcinomas and the Granulomas in the CT scans of the chest from a private dataset. We use the radiomic features of the nodules and the attached vessel tortuosity for the diagnosis. The private dataset includes 22 CTs for each nodule type, i.e., adenocarcinoma and granuloma. The dataset contains the CTs of the non-smoker patients who are between 30 and 60 years old. To automatically segment the delineated nodule area and the attached vessels area, we apply a morphological-based approach. For distinguishing the malignancy of the segmented nodule, two texture features of the nodule, the curvature Mean and the number of the attached vessels are extracted. Results We compare our framework with the state-of-the-art feature selection methods for differentiating Adenocarcinomas from Granulomas. These methods employ only the shape features of the nodule, the texture features of the nodule, or the torsion features of the attached vessels along with the radiomic features of the nodule. The accuracy of our framework is improved by considering the four selected features.
