An exposure-response relationship has been shown between muscle fatigue and its effects on keystroke durations. Since keystroke durations can readily be measured by software programs, the method has the potential as a non-invasive exposure assessment tool. However, the software based keystroke durations may be affected by keyswitch force-displacement characteristics. Thus, this study used a force platform to measure the keystroke durations and compared them to software measured keystroke durations in order to determine whether the software based keystroke durations can be used as a surrogate force exposure measures. A total of 13 subjects (6 males and 7 females) typed for 15 minutes each on three keyboards with different force-displacement characteristics. The results showed that the software based keystroke durations were more sensitive to the keyboard force-displacement differences than the force based measures. Although the digital signal based keystroke durations depend on the force-displacement characteristics, the high correlation between the two measures indicated that the keystroke durations derived from the digital signal approximated the true force derived keystroke durations, regardless of the keyboard force-displacement characteristics. Therefore, the software based keystroke durations could be used as a non-invasive, surrogate force exposure measure in lieu of the more invasive actual force measurements. 相似文献

This paper proposes a class of non‐parametric test procedures for testing the null hypothesis that two distributions, F and G, are equal versus the alternative hypothesis that F is ‘more NBU (new better than used) at specified age t0’ than G. Using Hoeffding's two‐sample U‐statistic theorem, it establishes the asymptotic normality of the test statistics and produces a class of asymptotically distribution‐free tests. Pitman asymptotic efficacies of the proposed tests are calculated with respect to the location and shape parameters. A numerical example is provided for illustrative purposes. 相似文献

Summary The co-worker approach offers workers additional armamentarium in working with families. Such advantages may never become manifest unless the workers both recognize possible limitations inherent in team endeavor and develop and even maximize the use of the co-worker relationship.The impact of the co-worker approach, as compared with other approaches, offers both personal and professional advantages. Personally, the worker engages in a continuing educational, self-awareness, and self-enhancing activity that contributes to his growth as a professional and as a person. The joy of relationships, mutual and reciprocal, is a part of this personal enhancement. Professionally, the promotion of therapy through examination and testing of new knowledge and skills based upon another professional's confirmation enhances the professional aspects of therapy. The use of co-workers further develops new styles of working with and in family constellations. 相似文献

This article presents the results of a comparative study on the effects of social welfare programs in selected developed countries. Using a fully comparable longitudinal data file from nationally representative household surveys, we estimate the poverty rate and poverty gap before and after social welfare transfers and taxes in order to identify the direct effects of social welfare on poverty. In general, the findings reveal that countries with conservative welfare regimes demonstrate higher poverty performance than do countries with liberal welfare regimes. In particular, the United States lagged behind through all periods under investigation, whereas Germany exhibited the highest performance in poverty reduction. 相似文献

Preliminary data on the test criteria of the Chinese version of the Multidimensional Orientation Toward Dying and Death Inventory (MODDI-F/chin) are presented. Data from a sample of Hong Kong college students (N = 256) revealed internal consistencies of the eight subtests between .68 and .91, on the whole favorable shape of frequency distributions, and evidence of construct as well as differential validity of the instrument. The use of the full set of 47 items is recommended for the time being. 相似文献

Message boards are possible places for sports fans to actively express and exchange their opinions. The purpose of this study is to explore the typology of message board uses on sports websites. The analysis of 1350 topics on eight Major League Baseball teams’ websites for 10 days revealed that: (1) the cognitive need of using message boards in a sports organization's website was an outstanding motivation; (2) sharing opinions was a new motivation category (compared to traditional uses and gratifications) that was found to be dominant; and (3) winning teams and losing teams’ message boards were significantly different in terms of number of topics, number of users, and optimism score; however, messages seemed to be optimistic. Implications for public relations practitioners suggest that the message board is an excellent monitoring tool for them as well as a fine communication tool between sports organizations and fans. 相似文献

k normal populations having common variance are used to construct two-sided and one-sided simultaneous prediction intervals
for the differences between the future means of independent random sample from each of these populations compared to a standard.
These prediction intervals are particularly useful if one has sampled the performance of several products and wishes to simultaneously
predict the differences between future sample mean performance of these products and a standard with a predetermined joint
probability. Methods on sample size determination are also given. The procedures are illustrated with a numerical example.
