Authority and Personality in M.M. Bakhtin\u27s Author and Hero in Aesthetic Activity

M.M. Bakhtin\u27s fundamental claim in his seminal essay Author and Hero in Aesthetic Activity situates verbal action as the most essential constituent of human personality. A careful reading of this text reveals important truths about the relationship between free individual personhood and the nature of the speech utterance. Bakhtin connects the human experience of speech to the life and person of Jesus Christ emphasizing the incarnation and the Trinitarian view of God as essential principles for understanding the creative power of the word and consequent liabilities. Bakhtin develops these theological and philosophical coordinates around a discussion of the author-hero relationship in the novel asserting that the verbal utterance is creatively involved in building and sustaining the inner personhood of those it addresses. Bakhtin\u27s critical conclusion substantiates that from whom a word is received, and to whom the spoken word appeals has weighty influence on the type and character of human personality, and that personality\u27s relationship to authority

Advancing theory and application of cognitive research in sport: Using representative tasks to explain and predict skilled anticipation, decision-making, and option-generation behavior

Objectives: Three main goals were addressed in this research. First, we tested the claims of two cognitive mechanisms that have been proposed to explain expert performance. This was done during assessment and intervention phases of decision making. Second, we tested the validity of an online test of perceptual-cognitive skill in soccer: The Online Assessment of Strategic Skill In Soccer (OASSIS). Third, we compared the OASSIS to other predictors of skill in soccer. Design: Over the course of a three-part experiment, participants completed an updated version of the option-generation paradigm employed by Ward, Ericsson, and Williams (2013), the OASSIS, and a battery of other cognitive tests. Performance on these tests was used to inform theory and validate the OASSIS as an applied tool for domain professionals. Method: NCAA Division 1 and recreational-level soccer players completed a battery of tests, both using paper/pencil (see Ward et al., 2013) and online. Results: Support for Long Term Working Memory theory (LTWM; see Ericsson & Kintsch, 1995) was observed during both phases of decision making, though the prescriptions of the Take-The-First heuristic (see Johnson & Raab, 2003) tend to hold, particularly within intervention phase. When used to predict skill-group membership, the OASSIS accounted for more variance than other domain-general tests of cognition. Furthermore, scores on the OASSIS correlated with other measures of perceptual-cognitive skill in soccer and the process-level predictions made by LTWM. Conclusions: Updates to our theoretical understanding of expert performance are provided and the validity of the OASSIS is demonstrated

Quantifying uncertainties in the sustainability evaluation of concrete materials considering regional characteristics in Japan

In the evaluation of concrete sustainability, what constitutes "sustainable" to one region may vary from another. This often leads to methodological forms of uncertainties that makes the evaluation process more complex. As such, this paper aims to quantify the effect of uncertainties in the regional context on the sustainability evaluation of concrete materials. This is carried out by quantifying the regional context through establishing a weighting scheme and then integrating the obtained weights into the sustainability analysis of concrete materials in tandem with uncertainty analysis. Japan is used as a case study because although it relatively appears as a homogeneous country, its prefectures possess unique characteristics that may make the sustainability evaluation of concrete materials vary across prefectures. Cluster analysis is carried out in the 47 prefectures of Japan using a set of regional context indicators. Five clusters are identified with varying characteristics and these are translated into different weighting schemes. The established weights are used in the sustainability evaluation of concrete materials using multi-criteria decision-making analysis. The results showed that one mix is the most sustainable for four of the clusters and a different mix is the most sustainable for the remaining cluster. When uncertainty analysis is conducted, the effect of the weights in the sustainability evaluation is explained by examining the average scores of the concrete mixes and the variance of the scores across the five clusters. This investigation facilitated the understanding of how regional differences and the uncertainties associated with it impact the evaluation of concrete sustainability

Matrix Concentration for Products

This paper develops nonasymptotic growth and concentration bounds for a product of independent random matrices. These results sharpen and generalize recent work of Henriksen-Ward, and they are similar in spirit to the results of Ahlswede-Winter and of Tropp for a sum of independent random matrices. The argument relies on the uniform smoothness properties of the Schatten trace classes

Barriers, enablers and initiatives for uptake of advance care planning in general practice: A systematic review and critical interpretive synthesis

Objectives How advance care planning (ACP) is conceptualised in Australia including when, where and how ACP is best initiated, is unclear. It has been suggested that healthcare delivered in general practice provides an optimal setting for initiation of ACP discussions but uptake remains low. This systematic review and critical interpretive synthesis sought to answer two questions: (1) What are the barriers and enablers to uptake of ACP in general practice? (2) What initiatives have been used to increase uptake of ACP in general practice? Design A systematic review and critical interpretive synthesis of the peer-reviewed literature was undertaken. A socioecological framework was used to interpret and map the literature across four contextual levels of influence including individual, interpersonal, provider and system levels within a general practice setting. Setting Primary care general practice settings Data sources Searches were undertaken from inception to July 2019 across Ovid Medline, Cumulative Index to Nursing and Allied Health Literature, Scopus, ProQuest and Cochrane Library of systematic reviews. Results The search yielded 4883 non-duplicate studies which were reduced to 54 studies for synthesis. Year of publication ranged from 1991 to 2019 and represented research from nine countries. Review findings identified a diverse and disaggregated body of ACP literature describing barriers and enablers to ACP in general practice, and interventions testing single or multiple mechanisms to improve ACP generally without explicit consideration for level of influence. There was a lack of cohesive guidance in shaping effective ACP interventions and some early indications of structured approaches emerging. Conclusion Findings from this review present an opportunity to strategically apply the ACP research evidence across targeted levels of influence, and with an understanding of mediators and moderators to inform the design of new and enhanced ACP models of care in general practice.

The effect of time constraint on anticipation, decision making, and option generation in complex and dynamic environments

Researchers interested in performance in complex and dynamic situations have focused on how individuals predict their opponent(s) potential courses of action (i.e., during assessment) and generate potential options about how to respond (i.e., during intervention). When generating predictive options, previous research supports the use of cognitive mechanisms that are consistent with long-term working memory (LTWM) theory (Ericsson and Kintsch in Phychol Rev 102(2):211–245, 1995; Ward et al. in J Cogn Eng Decis Mak 7:231–254, 2013). However, when generating options about how to respond, the extant research supports the use of the take-the-first (TTF) heuristic (Johnson and Raab in Organ Behav Hum Decis Process 91:215–229, 2003). While these models provide possible explanations about how options are generated in situ, often under time pressure, few researchers have tested the claims of these models experimentally by explicitly manipulating time pressure. The current research investigates the effect of time constraint on option-generation behavior during the assessment and intervention phases of decision making by employing a modified version of an established option-generation task in soccer. The results provide additional support for the use of LTWM mechanisms during assessment across both time conditions. During the intervention phase, option-generation behavior appeared consistent with TTF, but only in the non-time-constrained condition. Counter to our expectations, the implementation of time constraint resulted in a shift toward the use of LTWM-type mechanisms during the intervention phase. Modifications to the cognitive-process level descriptions of decision making during intervention are proposed, and implications for training during both phases of decision making are discussed

Long-term firn and mass balance modelling for Abramov Glacier in the data-scarce Pamir Alay

Several studies identified heterogeneous glacier mass changes in western High Mountain Asia over the last decades. Causes for these mass change patterns are still not fully understood. Modelling the physical interactions between glacier surface and atmosphere over several decades can provide insight into relevant processes. Such model applications, however, have data needs which are usually not met in these data-scarce regions. Exceptionally detailed glaciological and meteorological data exist for the Abramov Glacier in the Pamir Alay range. In this study, we use weather station measurements in combination with downscaled reanalysis data to force a coupled surface energy balance–multilayer subsurface model for Abramov Glacier for 52 years. Available in situ data are used for model calibration and validation. We find an overall negative mass balance of −0.27 mw.e.a-1 for 1968/1969–2019/2020 and a loss of firn pore space causing a reduction of internal accumulation. Despite increasing air temperatures, we do not find an acceleration of glacier-wide mass loss over time. Such an acceleration is compensated for by increasing precipitation rates (+0.0022 mw.e.a-1, significant at a 90 % confidence level). Our results indicate a significant correlation between annual mass balance and precipitation (R2 = 0.72).</p
