The reciprocal exchange of employees' work for pay that is central to employment relationships is viewed here through the lens of the psychological contract. A psychological contract involves promised inducements, promised contributions, delivered inducements, and delivered contributions: How an employee cognitively integrates these 4 elements is…

This paper investigates differences in how male and female students perceived a short message service (SMS) library catalog search service when adopting it. Based on a sample of 90 students, the results suggest that there are significant differences in perceived usefulness and intention to use but no significant differences in self-efficacy and…

This study explores the relationship between the structure of an existing social network and the structure of an emergent discussion-board network in an undergraduate university class. Thirty-one students were issued with laptop computers that remained in their possession for the duration of the semester. While using these machines, participants'…

This study investigated beliefs about HIV/AIDS to find out whether this variable could constitute an obstacle to change in attitudes to sex among undergraduate youths in South West Nigeria. A descriptive research design was adopted. A total of 1,420 undergraduate students in four different universities from four states were sampled. A…

This research presents an analysis of factors predicting job retention, job satisfaction, and job performance of workers with mental retardation. The findings highlight self-determination as a critical skill in predicting the three important employee outcomes. The study examined a hypothesized job retention model and the outcome of the three…

A growing controversy surrounds the strict interpretation of statistical significance tests in social research. Statistical significance tests fail in particular to provide estimates for the stability of research results. Methods that do provide such estimates are known as invariance or cross-validation procedures. Invariance analysis is largely…

Many important research hypotheses concern conditional relations in which the effect of one predictor varies with the value of another. Such relations are commonly evaluated as multiplicative interactions and can be tested in both fixed-and random-effects regression. Often, these interactive effects must be further probed to fully explicate the…

Exercise prescription guidelines emphasize the importance of individual preferences for different intensities, but such preferences have not been studied systematically. This study examined the hypothesis that the preference scale of the Preference for and Tolerance of the Intensity of Exercise Questionnaire would predict self-selected exercise…

Overall spiritual wellness, as well as 4 individual components of spiritual wellness, has been theoretically and empirically linked with depression. Prior to this investigation, no study has examined the relationship between spiritual wellness and depression by using a 4-component measurement model of spiritual wellness. In this study of older…

This article assesses the impact of religiosity on Christian leadership orientations. The theoretical model is taken from the study of Shee, Ji, and Boyatt (2002), which presupposes that quest religiosity is inversely related to the structured, human resource, political, and symbolic leadership frames, while intrinsic and extrinsic religiosity are…

Addresses three issues concerning the assessment of the overrating and underrating of academic competence: (1) the impossibility of separating effects of overrating and underrating from effects of perceived and actual competence; (2) the questionable validity of Connell and Ilardi's method; and (3) the proposal of a new method and its implications…

A relatively simple procedure for modeling periodic components in time series data is presented in this paper, along with an example of the procedure's use with communication data. Similar to multiple regression analysis, the described procedure has four steps that are based on information about periodic waves and their components, how to create…

Many topics in aging research address questions about group differences in prediction. Such questions can be viewed in terms of interaction or moderator effects, and use of appropriate methods to test these hypotheses are necessary to arrive at accurate conclusions about age differences. This article discusses the conceptual, methodological, and…
