Diversified Stress Testing of RDF Data Management Systems
"... Abstract. The Resource Description Framework (RDF) is a standard for conceptually describing data on the Web, and SPARQL is the query language for RDF. As RDF data continue to be published across heterogeneous domains and integrated at Web-scale such as in the Linked Open Data (LOD) cloud, RDF data ..."

. To address these shortcomings, our second contribution is the Waterloo SPARQL Diversity Test Suite (WatDiv) that provides stress testing tools for RDF data management systems. Using WatDiv, we have been able to reveal issues with existing systems that went unnoticed in evaluations using earlier benchmarks

Conservation of resources: A new attempt at conceptualizing stress
- American Psychologist
, 1989
"... ABSTRACT: Major perspectives concerning stress are presented with the goal of clarifying the nature of what has proved to be a heuristic but vague construct. Current conceptualizations ofstress are challenged as being too phenomenological and ambiguous, and consequently, not given to direct empirica ..."

empirical testing. Indeed, it is argued that researchers have tended to avoid the problem of defining stress, choosing to study stress without reference to a clear framework. A new stress model called the model of con-servation of resources i presented as an alternative. This resource-oriented model
Confirmation, Disconfirmation, and Information in Hypothesis Testing

"... Strategies for hypothesis testing in scientific investigation and everyday reasoning have interested both psychologists and philosophers. A number of these scholars stress the importance of disconnrmation in reasoning and suggest that people are instead prone to a general deleterious "confirmat ..."

The cost of diversity: The diversification discount and inefficient investment
, 2000
"... We model the distortions that internal power struggles can generate in the allocation of resources between divisions of a diversified firm. The model predicts that if divisions are similar in the level of their resources and opportunities, funds will be transferred from divisions with poor opportuni ..."

When diversity in resources and opportunities increases, however, resources can flow toward the most inefficient division, leading to more inefficient investment and less valuable firms. We test these predictions on a panel of diversified U.S. firms during
Stress, coping and social support processes: Where are we? What next?
- Journal of Health and Social Behavior,

Stochastic Trends and Economic Fluctuations
- American Economic Review
, 1991
"... Are business cycles mainly the result of permanent shocks to productivity? This paper uses a long-run restriction implied by a large class of real-business-cycle models-identifying permanent productivity shocks as shocks to the common stochastic trend in output, consumption, and investment-to provid ..."

However, in systems with nominal variables, the estimates of this common stochastic trend indicate that permanent productivity shocks
International diversified portfolio; welfare gains and capital flows.
- American Economic Review,
, 1968
"... The models of portfolio balance developed by Markowitz [51 and Tobin [8] explain the real world phenomenon of diversified asset holdings elegantly and properly. The models have been criticized, extended, and empirically tested; by now their basic content has become economic orthodoxy. Strangely, ..."

Who makes acquisitions? CEO overconfidence and the market’s reaction
, 2007

As a result, they overpay for target companies and undertake value-destroying mergers. The effects are strongest if they have access to internal financing. We test these predi ..."

At the end of the 8-week period, subjects in both groups were vaccinated with influenza vaccine. Results: We report for the first time significant increases in left-sided anterior
