Satisfactions and interests.

The problem of defining satisfaction and the difficulties in distinguishing interests and satisfactions are indicated. "Aside from the final, consummatory activity, satisfaction cannot be identified in terms of activities, as can interests… . Because opinion items are not as stable as interest items, it is doubtful that they can be as useful as interest items in predicting future behavior." 5 characteristics of interests are that they: are acquired, are persistent, vary in intensity, function in acceptance-rejection behavior, are indicated in readiness to act. "Interest tests are diagnostic because no two persons have acquired the same lists of activities nor are the activities classified in the same manner as liked or disliked. Moreover, people engaged in an occupation have to a marked degree similar interests, and so people in one occupation can be differentiated from members of other occupations." Major topics are: job satisfaction and job success; opinion, attitude, interest, and satisfaction; measurement of motivation. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

Conceptualizing and testing random indirect effects and moderated mediation in multilevel models: New procedures and recommendations.

The authors propose new procedures for evaluating direct, indirect, and total effects in multilevel models when all relevant variables are measured at Level 1 and all effects are random. Formulas are provided for the mean and variance of the indirect and total effects and for the sampling variances of the average indirect and total effects. Simulations show that the estimates are unbiased under most conditions. Confidence intervals based on a normal approximation or a simulated sampling distribution perform well when the random effects are normally distributed but less so when they are nonnormally distributed. These methods are further developed to address hypotheses of moderated mediation in the multilevel context. An example demonstrates the feasibility and usefulness of the proposed methods.

History and Renaissance of Construction Engineering and Management in Canada

Understanding the history of the construction engineering and management discipline in Canada can perhaps shed light on where the future of the discipline may lay and on external perceptions of the discipline. In its current state, the discipline in Canada is a unique model. Examining its positive and negative attributes will help inform strategic planning for construction research and education programs in Canada and in other countries as they adapt to rapid changes in their environments. The objective of this paper is to present sufficient information to make that examination possible. Its scope is limited to the last 200 years. Early pioneers in the discipline are described. Their careers are reflected in the developments that are summarized in the following discussion of the emergence of professional societies, and the educational and research infrastructure of the discipline in Canada. Recent developments in education and research are examined in more detail. Some final observations are then made based on this brief history.
