在以往关注不同类型创新行为对组织绩效影响的研究中,组织氛围与沟通、人力资源与管理和行政成本是三类较为常见的影响因素,但三者尚未综合形成统一的框架。本研究选取了领导干部任前公示这一以人力资源管理为内容的创新行为,构建了三因素影响组织绩效的过程假设。通过分析问卷调查数据,发现三因素之间存在显著的相关性,且若按照组织边界划分绩效内容,三因素均与组织的内部成长建设绩效显著相关,而同组织外部绩效水平相关程度较弱。依此认为,创新行为影响绩效是一个由人、财、物三因素互动,并依据创新本身特点内容有所侧重的过程。 相似文献

We discuss the analysis of mark-recapture data when the aim is to quantify density dependence between survival rate and abundance. We describe an analysis for a random effects model that includes a linear relationship between abundance and survival using an errors-in-variables regression estimator with analytical adjustment for approximate bias. The analysis is illustrated using data from short-tailed shearwaters banded for 48 consecutive years at Fisher Island, Tasmania, and Hutton's shearwater banded at Kaikoura, New Zealand for nine consecutive years. The Fisher Island data provided no evidence of a density dependence relationship between abundance and survival, and confidence interval widths rule out anything but small density dependent effects. The Hutton's shearwater data were equivocal with the analysis unable to rule out anything but a very strong density dependent relationship between survival and abundance. 相似文献

In clinical trials, investigations focus upon whether a treatment affects a measured outcome. Data often collected include pre- and post-treatment measurements on each patient and an analysis of the change in the outcome is typically performed to determine treatment efficacy. Absolute change and relative change are frequently selected as the outcome. In selecting from these two measures, the analyst makes implicit assumptions regarding the mean and variance-mean relationship of the data. Some have provided ad hoc guidelines for selecting between the two measures. We present a more rigorous means of investigating change using quasi-likelihoods. We show that both absolute change and relative change are special cases of the specified quasi-likelihood model. A cystic fibrosis example is provided. 相似文献

This paper compares the ergonomic risk assessment of a task for the upper extremities as determined by Rapid Upper Extremity Assessment (RULA) and the Strain Index (SI). The ergonomic risk to the upper extremities of 244 automotive assembly plant tasks were evaluated using RULA and SI. The outcomes of each tool were compared for each task. Results from this study provide practical insight into the methods used in each tool. This study compared only the ergonomic risk outputs from each tool; it does not pursue the question of which tool best predicts injury. The kappa score was 0.11, indicating little agreement between the outputs of the two tools. This is supported by the lack of monotonicity with a gamma score of 0.1. These results indicate that the risk assessment outcome of these two ergonomic assessment tools for the upper extremities do not agree. 相似文献

Although they have a recent work history, 70 to 80% of adults with multiple sclerosis are unemployed following their diagnosis. This high rate of unemployment constitutes a great loss of potential to the American economy. To help individuals with multiple sclerosis (MS) return to work or retain employment, rehabilitation professionals must understand the barriers resulting in unemployment and implement interventions to reduce or remove those concerns. In this article, Hershenson's systemic model of rehabilitation counseling is presented as a diagnostic scheme for identifying barriers to employment. Counselor consultation on barrier removal via reasonable accommodation is presented as one example of a rehabilitation intervention consistent with the systemic diagnostic model. 相似文献

The present study tested the theory that negative affect and one’s ability to tolerate distress is associated with failure
to quit gambling during an abstinence attempt. Specifically, 16 current pathological gamblers who had at least one sustained
period of gambling abstinence lasting a minimum of 3 months (i.e., delayed relapsers) and 16 current pathological gamblers
who had never remained abstinent for a period longer than 2 weeks (i.e., immediate relapsers), were assessed for baseline
levels of negative affect and stress reactivity, as well as faced with a psychological (mental arithmetic) and physical (breath
holding) stressor. Compared to the delayed relapsers, the immediate relapsers displayed higher levels of negative affect and
stress reactivity. Immediate relapsers also were less likely to persist on the psychological stressor, suggesting that one’s
ability to tolerate the initial discomfort of an abstinence attempt may play an important role in gambling treatment outcome.
The current project was completed in partial completion of the degree of Master of Arts in Psychology by the first author
