Various constrained frequencies of skilled model observation, under self-controlled conditions, were examined to determine whether there was an optimal frequency of modeling for learning a dance movement. Forty-eight participants with no previous dance/gymnastics experience first did a pre-test, then learned the skill over 60 interspersed observational and physical practice trials in one of four conditions that consisted of either (1) 25%, (2) 50%, (3) 75% modeling frequencies, or (4) no constraint imposed. This 60-trials acquisition phase was followed by a 24-hour post-test. Physical performance, scored by two external evaluators, revealed a significant main effect of Time from pre- to post-test (F(1, 44) = 120.43, p < .001). Cognitive representation scores revealed a main effect of Time for an image selection test (F(1, 44) = 39.09, p < .001), and a Time by Decision interaction for a forced-choice test (F(1.53, 67.48) = 7.00, p = .004). While learning was demonstrated for all measures, evidenced by higher scores at post-test than at pre-test, no main effect of Group was obtained. Consequently, the frequencies of modeling tested here under self-controlled learning conditions were equally beneficial for the learning of the novel dance skill.

This thesis analyses the sociological and historical genesis of enterprise skill formation in South Africa and its effective coordination. South Africa’s late nineteenth century development as an emerging economy contributed to the state often taking the lead and being at the forefront of efforts to ensure coordination in enterprise skill formation. But gradually, concerns shaped by issues related to labour supply motivated leaders in firms and enterprises to forge their own imprint on the coordination of enterprise skill formation. The thesis also shows how these concerns with the coordination of enterprise skill formation involved intellectuals and professionals who attempted to intervene on these matters. The thesis proceeds to elaborate the unique institutional architecture which was constructed at various junctures in the history of South Africa’s human resource and skill formation journey. Furthermore the thesis gives an insight into the coordination of enterprise skill formation which occurred in the period of apartheid induced reforms. The evidence however shows that even when regimes change and new political orders are established, it does not end the necessity for continuity in the coordination of enterprise skill formation. As is to be expected, the institutional, regulatory and instrumental content of the coordination of enterprise skill formation is more complex in the contemporary period (circa. 2017) than it was in the 1920s and 1930s. However, the goal striven toward then was for a more streamlined process which could contribute to a change and improvement in the existing practice of enterprise skill formation. Evidence shows that this has been ongoing for over a century. The thesis gives an intricate and detailed insight into the process of building a new coordinated skills development system that was intended to ensure the coordination of enterprise skill formation under a democratic post-apartheid political dispensation. In this period a levy-grant system underwritten by a national skills levy has been a central instrument of direct coordination into enterprise skill formation. The analysis that is provided traces the iterative steps that were treaded by policy makers and policy thinkers from at least the early 1920s as they confronted what may have appeared as an elusive enterprise skill formation process. This analysis is done with a great deal more depth for the period since the early 1990s.

archives@tulane.edu / Using hand-collected, professional designations of equity analysts as proxies for analyst accounting skills, this paper finds that analysts with strong accounting skills understand the net operating assets (NOA) anomaly. They provide more accurate and less optimistic earnings forecasts for firms with higher NOA. However, at the same time, they issue more optimistic recommendations for the same high NOA firms. This paper argues that conflicts of interests and the ways skilled analysts strategically incorporate the information into their outputs to achieve incentive-based goals drive this inconsistency. This strategic behavior of skilled analysts tends to create price discrepancies and might suggest that the NOA anomaly is more behavior-driven and less risk-oriented. / 1 / Miao He
