Employment demographics and attitudes that predict preferences for alternative pay increase policies
Dr. Daniel J. Koys Timothy J. Keaveny Robert E. Allen 《Journal of business and psychology》1989,4(1):27-47
A survey of 942 university staff employees shows that performance and cost of living are preferred over seniority as criteria upon which to base pay increases. Multiple regression analysis reveals that preferences for performance-based pay increases are most strongly related to perceptions that merit pay does not decrease co-worker cooperation, perceptions that performance differences exist among co-workers, employment in white collar jobs, and never having belonged to a union. Preferences for seniority-based and cost of living-based pay increases are most strongly related to the perceived need for a union, perceptions that merit pay reduces cooperation, education level, and gender. In addition, preferences for seniority-based pay increases are related to years of service.An earlier version of this paper was presented at the 1989 meetings of the Midwest Academy of Management. 相似文献

Age and scholarly impact 总被引:1,自引:0,他引:1
R Over 《Psychology and aging》1989,4(2):222-225
The claim that older scientists generate research of lower quality than do younger scientists was tested through two analyses in which the age distribution of authors of frequently cited articles in psychology journals was compared with the age distribution of authors of low-impact articles published in the same journals. Most high-impact articles were published by relatively young psychologists, but so were most low-impact articles. When allowance was made for relative numerical representation, there was no evidence that publications from older scientists have less impact. Results are discussed in the context of methodological issues in evaluation of relations between age and scientific achievement. 相似文献

In this study, we describe the process of transforming neuron polarization values that meet the assumptions of ratio data into ordinal data. This is a crisp-to-fuzzy set transformation. A computerized simulation of the application of this process is discussed and nonparametric methods of analyzing fuzzy-set data are presented. 相似文献

In this paper, we discuss the potential of HyperCard for research and instruction in psychology. First we give a general overview of the HyperCard program; after that, we present two HyperCard stacks as sample solutions for two specific research applications. Surveyor, a self-contained survey tool, is a HyperCard-based vehicle for developing, administering, and processing tests and surveys. Queston demonstrates how HyperCard can be used as a data-management and data-analysis tool during the stages of questionnaire development. Both stacks illustrate how flexible HyperCard is and how easy it is to use it to manage, analyze, and process data, to transfer data to other programs, and to print reports. HyperCard, unlike traditional applications, gives the user a great degree of control over the way information is stored, mainipulated, and presented. Although both stacks are custom-made for specific purposes, the concepts underlying the design can be generally applied and adapted for other purposes. 相似文献

Eleven subjects were asked to silently read slides of the letters “P” and “T,” and to view meaningless control slides similarly as they were presented visually. One-eighth-second electromyographic excerpts were sampled from the baseline and response periods. The data were then transformed into the frequency domain for inferential analyses. The mean power spectral frequencies for the response period were significantly lower than those for the base-line in the overall analysis. There were, however, no significant changes from baseline as a function of kind of stimulus (T, P, or Control) or muscle activated (lips or tongue). It was concluded that there was a generalized responding, not unique to the processing of the specific stimuli studied. Frequency analysis of EMG measures of covert behavior holds some promise of yielding unique information not available through traditional analysis procedures, but more sensitive methods than those used here would be required to demonstrate this. 相似文献

Some properties are discussed of regular polygons that may result from angular homeostatic processes in stable orbit. To characterize these homeostatic polygons we need to discuss the winding number, the sidedness (integer, fractional and irrational), multiplicity, envelopes, and density. A regular (i.e., equilateral, equiangular) polygon may be closed in one revolution about its unique center, in multiple revolutions, or not at all. A homeostatic polygon can be generated only if all vertices are included in a single polygon, which occurs if and only if the number of vertices and the number of revolutions required to complete the polygon are relatively prime. For the homeostatic polygon to have a finite number of sides (without repeating itself) the angle subtended by any two successive vertices at the center must be a rational multiple of 2. Biological implications of these properties are illustrated. 相似文献

The sentence verification technique (SVT), developed by Royer, Hastings, and Hook (1979), provides developmental and educational researchers with an alternative way of assessing text comprehension based on all of the information contained in a passage. Students must decide if test sentences have the same meaning as sentences that appeared in an original passage. The program described here automates the more laborious aspects of constructing SVT tests. The user must create a passage using a word processor. The program will prompt the user for information as needed. Finally, printable text files (SVT test and answer key) are generated. The program is written in BASIC for IBM and IBM-compatible computers. 相似文献

Traumatic brain injury can result in behavioral and physical deficits that require intensive post-acute residential rehabilitation. Behaviors targeted by such programs include basic self-care and living skills. We examined the efficacy of a behavioral training strategy to teach appropriate medical treatment of four different groups of simulated cold symptoms to an anoxic brain injured adult. The strategy included instructor prompting and feedback in the use of written task analyses and picture cues as self-administered prompts. Subsequent to baseline, the participant used written generic task analyses combined with picture cues and then, if necessary, written specific task analyses combined with picture cues to prompt appropriate self-treatment of the four types of colds. Written individualized task analyses, tailored to participant errors, were used to fade specific task analysis prompts and transfer stimulus control to the discriminative stimuli present in the picture cues. A multiple baseline design across responses showed that skill acquisition did not occur after generic task analysis training, but did so after specific task analysis training. The participant responded to all four types of colds for three consecutive trials at 100% correct under baseline conditions. Follow-up results indicated that transfer of stimulus control to the cold symptoms simulated by the picture cues alone did not maintain over time. Correct responding was retrained using generic and, if necessary, individualized task analysis training conditions. 相似文献
