The Introduction provides an overview of the central questions and the theoretical framework of the book. Since the early 1990s in Europe and the United States many artists critically re-appropriated religious, motifs, themes and images to produce works that cannot qualify as ‘religious,’ but remains in a dialogue with the visual legacy of mostly the Western, and more specifically the Catholic, version of Christianity. Present-day art does not embed religious images to celebrate them, but in order to pose critical questions concerning central aspects of the rules that regulate the status of images, their public significance, the conditions of their production and authorship, and their connection to an origin or tradition, a context or an author that guarantees their value. The motif of the true image or acheiropoietos (not made by a human hand) is related to central set of features that allow distinguishing between regimes or eras of the image. Its transformations provide a conceptual matrix for understanding of the reconfiguring relationships between art and religion. The introduction provides an overview of the theoretical context, the selection of artworks, bibliography on the subject and the chapters of the book.

The purposeof the article is to interpret the main determinants of the literary discussion of 1925–1928 years in the development of Ukrainian journalism during the XXth –early XXIst centuries.Research methodsthat enablethe implementation of the purpose and objectives: cultural-historical, comparative and hermeneutic, as well as the method of receptive aesthetics.Results and discussion. The article examines the ways of transformation of key provisions from the pamphletsof Mykola Khvylovyi in the journalistic activity of the scientist Yurii Sherekh, the writer Oksana Zabuzhko and the theater director Vlad Troiitskyi. Ideas such as “psychological Europe”, “Asian renaissance” and “romance of vitalism” are taken into account.It is proved that the concept of “psychological Europe” is significantly transformed in the works of Yurii Sherekh and Oksana Zabuzhko. Unlike Mykola Khvylovyi, the diaspora scholar notes the impossibility of such a value orientation, because provincialism as a central set of Ukrainians (according to Yurii Sherekh), in fact denies this possibility.It is noted that Oksana Zabuzhko, on the other hand, continues to develop this determinant in her essays, agreeing with the pamphleteer, but in modern coordinates it is necessary to focus on psychological America, not Europe. Thus, two interpretive views on this concept are traced and substantiated that is complete denial and rewriting of the idea.The comprehension of “Asian Renaissance” and the “romance of vitalism” determinants is interpreted through skepticism and the impossibility of these processes (Yurii Sherekh), through the addition of the concept –“Afro-Asian Renaissance” –to the unconscious support and relevance of the idea in modern Ukrainian processes.Conclusions.The study confirms the development and longevity of the concepts that are implemented in journalism, because chronologically the article covered materials written in different periods –from the first decades of the twentieth century tothe first decades of the twenty-first century.

1. The effects of cerebellar deficits in humans on scaling the magnitude of automatic postural responses based on sensory feedback and on predictive central set was investigated. Electromyographic (EMG) and surface reactive torques were compared in patients with anterior lobe cerebellar disorders and in normal healthy adults exposed to blocks of four velocities and five amplitudes of surface translations during stance. Correlations between the earliest postural responses (integrated EMG and initial rate of change of torque) and translation velocity provided a measure of postural magnitude scaling using sensory information from the current displacement. Correlations of responses with translation amplitude provided a measure of scaling dependent on predictive central set based on sequential experience with previous like displacements because the earliest postural responses occurred before completion of the displacements and because scaling to displacement amplitude disappeared when amplitudes were randomized in normal subjects. 2. Responses of cerebellar patients to forward body sway induced by backward surface displacements were hypermetric, that is, surface-reactive torque responses were two to three times larger than normal with longer muscle bursts resulting in overshooting of initial posture. Despite this postural hypermetria, the absolute and relative latencies of agonist muscle bursts at the ankle, knee, and hip were normal in cerebellar patients. 3. Although they were hypermetric, the earliest postural responses of cerebellar patients were scaled normally to platform displacement velocities using somatosensory feedback. Cerebellar patients, however, were unable to scale initial postural response magnitude to expected displacement amplitudes based on prior experience using central set. Randomization of displacement amplitudes eliminated the set effect of amplitude on initial responses in normal subjects, but responses to randomized and blocked trials were not different in cerebellar patients. 4. Cerebellar patients compensated for hypermetric responses and lack of anticipatory scaling of earliest gastrocnemius activity by scaling large, reciprocally activated tibialis and quadriceps antagonist activity with the displacement velocity and amplitude. Correlations between these antagonist EMG integrals and displacement amplitudes were preserved when amplitudes were randomized, suggesting that feedback-dependent and not set-dependent mechanisms were responsible for scaling of antagonists by cerebellar patients. Antagonist compensation for initial hypermetric responses also could be induced in normals when they overresponded to unexpectedly small amplitudes of surface displacements. 5. The major effects of anterior lobe cerebellar damage on human postural responses involves impairment of response magnitude based on predictive central set and not on use of velocity feedback or on the temporal synergic organization of multijoint postural coordination.(ABSTRACT TRUNCATED AT 400 WORDS)

1. The effect of central set on automatic postural responses was studied in humans exposed to horizontal support-surface perturbations causing forward sway. Central set was varied by providing subjects with prior experience of postural stimulus velocities or amplitudes under 1) serial and random conditions, 2) expected and unexpected conditions, and 3) practiced and unpracticed conditions. In particular, the influence of central-set conditions was examined on the pattern and magnitude of six leg and trunk electromyograph (EMG) activations and associated ankle torque responses to postural perturbations with identical stimulus parameters. 2. The scaling of initial agonist integrated EMG (IEMG) and torque responses to postural perturbation amplitude disappeared when perturbation amplitudes were randomized. This finding suggests that the initial magnitude of postural responses were centrally set to anticipated postural perturbation amplitudes based on sequential experience with the stimulus. 3. Expectation of postural stimulus amplitude had a significant effect on initial torque responses; subjects overresponded when a larger perturbation was expected and underresponded when a smaller perturbation was expected. Expectation of postural stimulus velocity had a smaller effect on initial torque responses, and subjects consistently overresponded when the velocity of the perturbation was unexpected. This difference in amplitude and velocity expectation may be because of the capacity to encode stimulus velocity, but not amplitude information, into the earliest postural responses of the current trial. The relative strength of amplitude and velocity central-set effects varied widely with individual subjects. 4. Central-set conditions did not affect initial EMG response latencies (100 +/- 20 ms, mean +/- SD) or the relative onset of proximal and distal agonists and antagonists. Unexpected or unpracticed stimulus amplitudes, however, were associated with significant late activation of ankle antagonist, tibialis. Thus errors in initial response magnitude because of central-set effects appear to be partially corrected by reciprocal antagonist activity. Agonist IEMG, however, did not always reflect significant changes in torque responses with central-set conditions. 5. Expectation of postural stimulus amplitude and velocity had two different types of effects on the magnitudes of postural responses: 1) a directionally specific, central-set effect consisting of either increased or decreased responses, depending on expectation of stimulus amplitude; and 2) a nonspecific enhanced response to novel stimulus velocities with a gradual reduction when a velocity was presented repeatedly. Two different neural mechanisms are proposed for these two adaptive effects. 6. Reduction of postural response magnitude and antagonist activity during practice may be partially explained by adaptive mechanisms based on expectation because of prior experience with stimulus velocity and amp
