In process identification (i.e., dynamic model development) information on the precision and reliability of a parameter estimate is conveyed y a confidence interval. The best confidence interval is the one with the shortest width for a given level of confidence. Confidence intervals iden as the standard error increases or as the number of estimated parameters increases. When the value of a para...

For public transit operators in the U.S., neither fare increases nor fare reductions have been successful in boosting revenues. A different kind of strategy is needed, one that can produce more revenue for transit operators than it costs. This article argues that deep discount group pass (DDGP) programs can accomplish this goal. DDGP programs provide groups of people with unlimited-ride transit...

One line of theorizing suggests considering death reminders—i.e., mortality salience (MS) inductions—unique in their effect on worldview defenses (e.g., Pyszczynski et al., 2006). Other theorizing suggests that meaning and certainty threats produce effects similar to MS and thus that these threats be considered theoretically equivalent (e.g., Proulx & Heine, 2006; McGregor, 2006). To help recon...

Cost certainty and time certainty are major concerns to both clients and contractors, as they have a direct impact on resources. An international study of contractors’ cost certainty and time certainty is presented. Based on the performance and practice of contractors in Japan, the UK and the US, the multiple regression analysis reveals cost certainty to be influenced by time certainty and its ...

The main purpose of the study is to examine the causal relationship between government revenues and expenditures of the Jordan government over the period from 1990 to 2011 using Granger causality and VECM tests methodology. Which provides channels of causation between government revenues (GR) and government expenditures (GE).The empirical results show that bidirectional causality running betwee...
