Error Of Measurement

To measure the relative role of left- or right-hemispheric processes involved both in creation of works of art and their perception, a procedure was derived based on calibrated expert estimations (of works or their authors). The resulting instrument for measurements consists of 7-10 scales and two sets of ‘contrastive objects’ (‘tuning forks,’ each containing 7-12 objects). The asymmetry is reflected by appropriate index which varies from –1 to +1 (‘pure’ right- and ‘pure’ left-hemispheric dominance, respectively). It occurs possible to eliminate subjectivity both of experts and researchers (compilers of the instrument). The method was used in evolutionary studies concerning 102 composers, 240 painters, etc.; the error of measurement was usually 3-5%. Evolutionary curves built on the basis of these indices, permitted to observe periodical switching between left and right styles in music, painting, theatre staging, and poetry.

Sociocultural Systems

Although psychologists typically see creativity as an individual-level event, sociologists and cultural anthropologists are more likely to view it as a sociocultural phenomenon. This phenomenon takes place at the level of relatively large and enduring collectives, such as cultures, nations, and even whole civilizations. This chapter reviews the extensive research on such macro-level creativity. The review begins with a historical overview before turning to the cross-sectional research on the creative Ortgeist, a subject that encompasses the factors that influence the relative creativity of both preliterate cultures and entire modern nations. From there the chapter turns to role of the Zeitgeist in affecting the creativity of civilizations across time—the rise and fall of creative activity. This research examines both quantitative and qualitative causes that operate both short- and long-term.

Process Constraints

Musicians have long framed their creative activity within constraints, whether imposed externally or consciously chosen. As noted by Leonard Meyer, any style can be viewed as an ensemble of constraints, requiring the features of the artwork to conform with accepted norms. Such received stylistic constraints may be complemented by additional, voluntary limitations: for example, using only a limited palette of pitches or sounds, setting rules to govern repetition or transformation, controlling the formal layout and proportions of the work, or limiting the variety of operations involved in its creation. This chapter proposes a fourfold classification of the limits most often encountered in music creation into material (absolute and relative), formal, style/genre, and process constraints. The role of constraints as a spur and guide to musical creativity is explored in the domains of composition, improvisation, performance, and even listening, with examples drawn from contemporary composers including György Ligeti, George Aperghis, and James Tenney. Such musical constraints are comparable to self-imposed limitations in other art forms, from film (the Dogme 95 Manifesto) and visual art (Robert Morris’s Blind Time Drawings) to the writings of authors associated with the Oulipo (Ouvroir de littérature potentielle) such as Georges Perec and Raymond Queneau.

Abstract The goal of glioma surgery is maximal safe resection in order to provide optimal tumor control and survival benefit to the patient. There are multiple imaging modalities beyond traditional contrast-enhanced magnetic resonance imaging (MRI) that have been incorporated into the preoperative workup of patients presenting with gliomas. The aim of these imaging modalities is to identify cortical and subcortical areas of eloquence, and their relationship to the lesion. In this article, multiple modalities are described with an emphasis on the underlying technology, clinical utilization, advantages, and disadvantages of each. functional MRI and its role in identifying hemispheric dominance and areas of language and motor are discussed. The nuances of magnetoencephalography and transcranial magnetic stimulation in localization of eloquent cortex are examined, as well as the role of diffusion tensor imaging in defining normal white matter tracts in glioma surgery. Lastly, we highlight the role of stimulated Raman spectroscopy in intraoperative histopathological diagnosis of tissue to guide tumor resection. Tumors may shift the normal arrangement of functional anatomy in the brain; thus, utilization of multiple modalities may be helpful in operative planning and patient counseling for successful surgery.

Epistemological Dimension

Critics of the “New” Natural Law (NNL) theory have raised questions about the role of the divine in that theory. This paper considers that role in regard to its account of human rights: can the NNL account of human rights be sustained without a more or less explicit advertence to “the question of God’s existence or nature or will”? It might seem that Finnis’s “elaborate sketch” includes a full theory of human rights even prior to the introduction of his reflections on the divine in the concluding chapter of Natural Law and Natural Rights. But in this essay, I argue that an adequate account of human rights cannot, in fact, be sustained without some role for God’s creative activity in two dimensions, the ontological and the motivational. These dimensions must be distinguished from the epistemological dimension of human rights, that is, the question of whether epistemological access to truths about human rights is possible without reference to God’s existence, nature, or will. The NNL view is that such access is possible. However, I will argue, the epistemological cannot be entirely cabined off from the relevant ontological and motivational issues and the NNL framework can accommodate this fact without difficulty.

The rate of bank retreat was measured using erosion pins on the alluvial banks of the rivers in the Podhale region (the boundary zone between Central and Outer Carpathians) during the hydrological year 2013/2014. During the winter half-year (November–April), the bank retreat was mainly caused by processes related to the freezing and thawing of the ground (swelling, creep, downfall). During the summer half-year (May–October), fluvial processes and mass movements such as lateral erosion, washing out, and sliding predominated. The share of fluvial processes in the total annual amount of bank retreat (71 cm on average) was 4 times greater than that of the frost phenomena. Erosion on bank surfaces by frost phenomena during the cold half-year was greatest (up to 38 cm) on the upper parts of banks composed of fine-grained alluvium, while fluvial erosion during the summer half-year (exceeding 80 cm) mostly affected the lower parts of the banks, composed of gravel. The precise calculation of the relative role of frost phenomena in the annual balance of bank erosion was precluded at some stations by the loss of erosion pins in the summer flood.
