    Citation Statistics

    This is a report about the use and misuse of citation data in the assessment of scientific research. The idea that research assessment must be done using ``simple and objective'' methods is increasingly prevalent today. The ``simple and objective'' methods are broadly interpreted as bibliometrics, that is, citation data and the statistics derived from them. There is a belief that citation statistics are inherently more accurate because they substitute simple numbers for complex judgments, and hence overcome the possible subjectivity of peer review. But this belief is unfounded.Comment: This paper commented in: [arXiv:0910.3532], [arXiv:0910.3537], [arXiv:0910.3543], [arXiv:0910.3546]. Rejoinder in [arXiv:0910.3548].

    Effect of Selected Essential Oils on Brown Recluse Spider Control

    Loxosceles reclusa isconsidered a pest throughout its range in the US due mostly to the effects of its venomous bite (Sandidge and Hopwood, 2005). Management techniques include the use of pesticides to target this dangerous synanthropic organism. Essential oils, commonly used for various health benefits, have been previously used as a method of pest control (Koulet al, 2008). Studies have shown varying results when tested on different insects and pests (Regnault-Roger et al, 2011). Their effect on L. reclusa is still undetermined. Thus, we tested the potential of essential oils as an effective method of control for L. reclusa. Results from our experiment indicated that the selected essential oils had a varied effect with overall low mortality

    An Experimental Investigation of the Effects of Contract Frame and Discretion in Performance Evaluation on Effort

    The design of incentive compensation plans is critical to a company’s success. This study develops and validates a theoretical model to examine how incentive contract framing affects effort. This study uses an experiment to observe the effect of the manipulation of incentive contract frame and the presence or absence of principal discretion in performance evaluation on effort. The results of the experiment show that when principal discretion in performance evaluation is absent, penalty contracts induce greater effort than bonus contracts. The results of the experiment also demonstrate that the interaction of principal discretion in performance evaluation and contract frame influences how agents view the perceived fairness of their incentive contract. Specifically, principal discretion in performance evaluation increases perceived fairness under a penalty contract but not under a bonus contract. This study also extends prior research by documenting that perceived fairness explains how incentive contract frame affects trust and effort
