In this paper, we develop a methodology for determining where the time goes between when a user clicks on a Web page and when the page appears on the display. Our methodology uses only client-based measurements, requiring no special support from the Internet or the Web server. This is crucial

A critical first step to improving existing and designing future wide-area networks is an understanding of the load placed on these networks. Efforts to model traffic are often confounded by atypical traffic --- traffic particular to the observation site not ubiquitously applicable. The causes

of research on human change. Major reviews include In essence, research on individual change has been plagued by inadequacies in conceptualization, measurement, and design. Brief reviews of these inadequacies follow. 1. Conceptualization. In any research context, a model of the phenomena under study

Data transport methods with end-to-end performance guarantees are required by the next generation distributed computing applications. Transport methods based on default best-effort IP networks are not capable of providing such guarantees due to complex traffic distributions in wide-area networks

graph theory, a mathematical discipline widely used in economic sociology. 2 Graph theory provides us with tools for describing networks at a "macro" level and for measuring the relative importance, or "centrality," of each actor in the network. Our centrality measures capture five

as a significant moderator of effects sizes in our meta-analysis of eating disorder prevention programs Nested Data Modeled Incorrectly Virtually all parametric inferential tests, such as repeated measures analysis of variance, growth curve, and survival models, used to test for intervention effects

, measures, and illness behavior. Methods: A search of MEDLINE and PsycLIT/ PsycINFO for abstracts from 1980 to April 2001 was performed; principal investigators in the field were contacted and article reference lists were used to retrieve additional relevant articles. Two hundred forty-four studies were

The authors tested a model of antecedents and outcomes of newcomer adjustment using 70 unique samples of newcomers with meta-analytic and path modeling techniques. Specifically, they proposed and tested a model in which adjustment (role clarity, self-efficacy, and social acceptance) mediated

Home visiting programs for families with young children have been in effect for many years; however, this is the first comprehensive meta-analytic effort to quantify the usefulness of home visits as a strategy for helping families across a range of outcomes. Sixty home visiting programs contributed

The cosmogenic nuclide exposure history method is undergoing major developments in analytical, theoretical, and applied areas. The capability to routinely measure low concentrations of stable and radioactive cosmogenic nuclides has led to new methods for addressing long-standing geologic questions
