A Performance

Foot preference and performance characteristics of gross-motor lower-limb speed of tapping were examined in 606 4- to 6-yr.-olds. Analysis indicated no effect for gender; however, speed of foot tapping increased significantly across the three ages, suggesting an association with selected developmental (neuromuscular) processes. Contrary to earlier reports on handedness, there was no statistical evidence that mixed- or left-footers were at a performance disadvantage compared to right-footers. All groups performed best with the right foot, limb differentiation (right versus left) being significant for the right- and mixed-footed groups. Speculation about maturational and environmental influences is given.

Different Origin

Abstract Doubts surrounding the potential adverse effects of antimicrobial preservatives have modified the demand of consumers, who increasingly insist on the production of low-level and even preservative-free cosmetics. Protection of the product against microbial contamination is therefore focused on the packaging. This has prompted the emergence of a highly diverse array of so-called “protective”, “overprotective”, and “barrier” packaging. However, these designations are not normalized and the choice of the right packaging adapted to each cosmetic product is still essentially empirical, hazardous, and time consuming. The Cosmetic Valleys cluster has launched a commission to define a complete and experimentally-validated method to classify the level of protection of cosmetic packaging against microbial contamination. As reported herein, this required the development a specific bacteriostatic medium that can be used for seven days and an in vitro procedure that reproduces in-use contamination and consumer practices. Based on tests performed on over 800 packages of different origin and performance characteristics, we propose a classification, divided into six grades, to differentiate the protective efficiency of cosmetic packaging. This work can be considered as a first step towards a regulatory text.

Insight Into

In 1957 Poulton was the first to coin the terms ‘open’ and ‘closed’ skills His analysis, based upon the predictability of environmental influences, suggests a vertical approach from failure to success. Knapp later, realizing that, even in unpredictable situations, an athlete could achieve success, placed skills on a horizontal continuum with success possible at any point. All authors since that time have continued to use the horizontal continuum for ‘closed-open’ skill analysis. The horizontal continuum suggests that skills may be entirely closed (spatial restrictions), entirely open (spatial and temporal restrictions), or partly closed and partly open. The ‘grey area’ of the closed-open continuum is, however, futile for skill analysis. If a skill is performed in a stationary environment, at the athlete's own pace, it is closed. If a skill is performed in a moving environment, in which external factors, no matter how small, may adversely affect the outcome of the movement, the skill is open. The “Widdop ‘Y’” suggests that skills be introduced in a closed environment. Those skills which are then to be applied in a closed environment follow the closed stem of the ‘Y,’ concentrate upon repetition, and emphasize technique, poise, and efficiency. Skills which are to be applied in a moving environment follow the open stem of the ‘Y’ and concentrate upon insight into the display, selection, and performance at the right time. Theoretically the ‘Y’ may become diamond-shaped showing that, when a skill is performed successfully 100 percent of the time, external factors no longer adversely affect performance in any situation.

The Relationship

Today the performance measurement of Muhammadiyah Luwuk uUniversity’s performance has not formulated yet based on University’s vision and mission. It will affect the strategic steps needed and performance improvement efforts in the future.  Human resource scorecard is the right system to be applied in Muhammadiyah Luwuk University. The purpose of this study is to designed a performance measurement system at Muhammadiyah Luwuk University using the Human Resource Scorecard with four perspectives: stakeholder, academic management and kemuhammadiyaan, operational and innovation, as well as and learning. Data was analyzed by analytical hierarchy process method. This research was conducted by distributing questionnaires, focus group discussions and in-depth interview with stakeholders at Muhammadiyah Luwuk University. The results showed that there were 14 strategic objectives and 33 key performance indicators to be achieved by the priority objectives, which are: empowerment and development of faculty, increased administrative process quality, improved sound budget performance and, improvement of the relationship with stakeholders.
