BACKGROUND The prospect of assessing cognition longitudinally and remotely is attractive to researchers, health practitioners, and pharmaceutical companies alike. However, such repeated testing regimes place a considerable burden on participants, and with cognitive tasks typically being regarded as effortful and unengaging, these studies may experience high levels of participant attrition. One ...

s: Background: Tooth wear is a condition that encompasses attrition, abrasion and erosion and has a multifactorial etiology. Prevalence of tooth wear is reported to be between 5-50%.This wide range probably reflects the various parameters used in assessing of tooth wear and the difficulty in differentiating between the types of tooth wear. Diagnosing tooth wear and eliciting the etiological fac...

The goal of dentistry is to preserve functional dentition to promote the general health, longevity, and productivity of the horse; however, throughout recorded equine dental history, exodontia has been the primary treatment for diseased teeth. This treatment predisposes the equine dentition to subsequent periodontal disease, malocclusion, and additional tooth loss. Restorative dentistry is the ...

This paper uses rich new data on New York State teachers to: determine how much variation in the average attributes of teachers exists across schools, identif, schools that have the least-qualified teachers, assess whether the distribution has changed over time, and determine how the distribution of teachers is impacted by attrition and transfer, as well as by the job matches between teachers a...

Many companies survey employees about their managers yet it is unclear whether this information is, or should be used to evaluate and compensate managers. Data from a high-tech firm reveals that survey measures are associated with employees’ lower attrition, higher promotions, higher salary increases, and higher engagement, but have only a limited relation to subjective performance scores. The ...

The study of the aerodynamics related to the improvement in the acting of airplanes and automobiles with the objective of being reduced the effect of the attrition of the air on structures, providing larger speeds and smaller consumption of fuel. The application of the knowledge of the aerodynamics not more limits to the aeronautical and automobile industries. Therefore, this research aims to d...

We examine how the criteria for choosing estimation samples (peer firms) affect the ability to detect discretionary accruals, using several variants of the Jones (1991) model. Researchers commonly estimate accruals models in cross-section, and define the estimation sample as all firms in the same industry. We examine whether firm size performs at least as well as industry membership as the crit...

This policy brief examines the distribution, effectiveness, and persistence of individuals entering the teaching profession with different forms of preparation. In comparison to teachers prepared by the University of North Carolina system, we find that: (1) North Carolina Independent College and University prepared teachers are less effective in middle grades mathematics and 5th and 8th grade s...

In a new scheme for hedge fund managerial compensation known as the first-loss scheme, a fund manager uses her investment in the fund to cover any fund losses first; by contrast, in the traditional scheme currently used in most U.S. funds, the manager does not cover investors’ losses in the fund. We propose a framework based on cumulative prospect theory to compute and compare the trading strat...

There is a vast collection of scenarios where people have to time a decision optimally vis-a-vis the decision of other, examples include market entry and exit, corporate restructuring, mergers and acquisitions and so on. In economics these strategic decisions are typically studied with timing games, either tailoring the question to fit a War of Attrition(having more predecessors helps), or to a...
