This study examined the relationship between two methods of assessing cognitive laterality, one by responses on a preference inventory and the other by assessing asymmetry of hemispheric performance on tests associated with processing in the left or right cerebral hemispheres. 87 graduate students were administered both instruments. Analysis showed negative or no relations between the preference and performance measures. The performance tests associated with left- and right-hemisphere functions were taken directly or adapted from tests showing left- or right-hemisphere superiority in unilateral lesioned patients, brain-divided patients, and normal subjects. The preference inventories were constructed on the basis of the same research but have not been validly related to brain functions. The results of this study suggest that the two types of instruments do not measure the same thing.

We examine the relationship between quality-based manufacturing strategy and the use of different types of performance measures, as well as their separate and joint effects on performance. A key part of our investigation is the distinction between financial and both objective and subjective nonfinancial measures. Our results support the view that performance measurement diversity benefits performance as we find that, regardless of strategy, firms with more extensive performance measurement systems—especially those that include objective and subjective nonfinancial measures—have higher performance. But our findings also partly support the view that the strategy-measurement “fit” affects performance. We find that firms that emphasize quality in manufacturing use more of both objective and subjective nonfinancial measures. However, there is only a positive effect on performance from pairing a qualitybased manufacturing strategy with extensive use of subjective measures, but not with objective nonfinancial measures.

ABSTRACT:Background:Constructional impairment following left vs. right hemisphere damage has been extensively studied using drawing tasks. A confounding factor in these studies is that right-handed patients with left hemisphere damage (LHD) are often forced by weakness to use their non-dominant (left) hand or hemiparetic dominant hand. Qualitative differences in the drawing characteristics of left and right hand drawings by normal subjects have not previously been characterized. The present study was undertaken to determine the qualitative differences between left and right hand drawings of normal subjects.Methods:Thirty right-handed, elderly subjects without a history of neurological disease were asked to draw, from memory, seven objects using the right and left hand. Half of the subjects were randomly assigned to draw with the left hand first, and half the right hand first. Right and left hand drawings were compared using a standardized scoring system utilized in several previous studies of drawing in focal and diffuse neurological disease. Each drawing was scored on eighteen criteria. Right and left hand drawing scores were then compared using the t-test for paired samples or the Wilcoxon matched-pairs testResults:Drawings made using the left hand were found to be significantly simpler, more tremulous and of poorer overall quality than drawings made by the same subjects using the right hand.Conclusions:The deficits found in left versus right hand drawings of normals are similar to those found in patients with LHD, suggesting that much of the drawing impairment seen following LHD is due to an elementary motor disturbance related to use of the non-dominant hand.

Although the majority of research in theory of mind (TOM) has focused on young children or individuals with autism, recent investigations have begun to look at TOM throughout the lifespan and in other neurological and psychiatric populations. Some have suggested that TOM may represent a dissociable, modular brain system that is related to, but separable, from other brain functions including executive functions (EF). Recently, studies have shown that TOM performance can be compromised following an acquired brain insult (e.g, damage to the right hemisphere). However, the relationship of such impaired TOM performance to other brain functions in these cases has not been explored. This study investigated the effects of both normal human aging and Parkinson's disease on TOM. The relationship of TOM performance and EF in these groups was also examined. The results suggested that although TOM performance appeared compromised in the group of individuals with Parkinson's disease, the elderly control participants were relatively unimpaired relative to younger individuals. Significant relationships between several measures of TOM and EF were also found. The implications of these findings, and also the finding that failure on one measure of TOM did not necessarily predict failure on all measures of TOM, are discussed. (JINS, 2000, 6, 781–788.)

The objective of this study was to evaluate a number of inner glove liners used to protect the skin from latex proteins and chemical skin sensitizer found in gloves. A battery of performance tests were used for evaluating the inner gloves. Besides these, objective measurements such as skin temperature, skin conductance, and skin moisture content were measured. A series of subjective discomfort/comfort measures were also taken. Seventeen health care providers participated in this experiment where four liner conditions were evaluated at two temperatures. Some of the measures were recorded before and after the tests, while some other measures were recorded every fifteen minutes. Thus each subject participated in eight trials (4 liners X 2 temperatures). The tests were of two hours duration. Sweat, pegboard test, and discomfort measures were the best discriminators of liners, while the other subjective and objective measures were not.

Approximately 220 of the 700 firms whose stock was traded on the main French markets had an employee stock ownership plan at the end of the year 2000. Average ownership was 3.7%. Employee ownership can be implemented for many reasons, and the relationship between ESOPs and performance still remains unclear. The purpose of this research is thus to determine how employee ownership can affect corporate performance and risk in France. This study improves upon previous work by using ownership, performance and risk variables, as well as control variables (sector, size, debt, growth), applied to a large sample of French firms. Cross-sectional regressions show some positive links between the presence of ESOPs and some financial performance measures, such as the return on equity and the return on investments. Links between ESOPs and risk variables are more complicated. The presence of ESOPs reduces the return on equity variability, but the more employee ownership there is the more the beta coefficient increases. This result seems to show that investors tend to consider firms with ESOPs to be more risky, even if their profitability is more stable. Within the limitations of these results, we propose a general model introducing the concept of social capital.

Abstract The contribution of dynamic capabilities (DCs) to firm performance remains unclear and at the centre of debate. Based on a systematic literature review of 92 quantitative articles, the purpose is to explore how the DC–performance relationship have and should be assessed in the future. The most promising approach seems to be indirect, as it appears that DCs primarily causes change and intermediate outcomes, though far from being the most hypothesized relationship. Moreover, investigations employ a continuum of conceptualizations, ranging from very specific DCs to generic sets with theoretical divergences and overlapping. The same applies to the varied performance measures adopted, evidencing that the literature still has a long way to go. Based on a structured synthesis and analysis of existing studies, a conceptual model, recommendations and future avenues are proposed, along with areas of attention, which have both managerial and practical relevance, contributing to advancement within this research stream.

Two investigations of the relationship between “worry” ( W) and “emotionality” ( E), components of test anxiety, and performance expectancy are reported. Undergraduate and graduate students responded to a modified form of Mandler and Sarason's TAQ containing 5 W and 5 E items. W was found to be negatively related to expectancy. E was not consistently related to expectancy but varied as a function of the external cues of the testing situation.

Using the results of a survey of Russian corporate executives in the late 2010 we reveal the relationship between the actions undertaken in 2009-2010 and performance measures. Only sustainable cost leadership strategic position, partially based on intensive use of subcontractors and consultants, secures somehow the immediate future of Russian industrial companies, as such a position results in a positive dynamics of orders backlog. Suggestions for the government economic policies are made.

The study reported here is part of a continuing research program investigating the links between psychological stress responses and performance in a variety of settings. A battery of psychological and cognitive measures designed to assess stress perceptions, coping resources, and cognitive performance was administered at selected times in association with the daily test activities of smoke and decontamination platoon operations. During testing soldiers wore the full chemical protective ensemble including mask (MOPP IV). Canonical correlation analyses were computed to examine the relationship between the stress perception measures (predictor variables) and cognitive performance measures (outcome variables). The direction of the results indicates that as subjects experience an increase in their perception of the situation as stressful their corresponding performance declines. These results are consistent with the literature and indicate that the stress perception measures and performance measures used in this study are sensitive indicators of stress.
