Experts may have more information about the potential of projects in their area, but may also be biased. This paper develops a framework for separately identifying the effects of bias and information on expert evaluation and applies it in the context of peer review at the National Institutes of Health (NIH). I find that while reviewers are biased in favor of applications from their own subfield...

Owing to budget constraints, managers should balance the expenditure requirement of IT and marketing department. This paper offers a new method to evaluate the importance of IT department and marketing department. It introduces the triangular three-stage DEA model to measure the expenditure efficiency and effectiveness. Using the data of the hotel industry of Macao, it shows that IT and marketi...

The current challenge concerning renewable energy sources resides in making them efficient and competitive in comparison with traditional ones. This assessment cannot neglect environmental performances. In particular, envisaging a sustainability perspective, this task must be accomplished from a wider, and then holistic, viewpoint. At this purpose authors identified emergy analysis as a valid a...

Data envelopment analysis (DEA) is a method for estimating efficiency of decision making units (DMU).The method done by means of weighted output to input ratio with the weights being optimal virtual prices of such activities for all units. Cross efficiency evaluation has long been proposed as an alternative method for ranking DMUs. The major problem that reduced the usefulness of cross efficien...

We present an efficiency model for data warehouse operations and analyze a data set to evaluate the model. The model contains salient variables to evaluate the efficiency of an organization’s data warehouse operations for refresh processing and query production. The variables in the model include resource consumption (labor usage and computing budgets), system usage measures (users and queries)...

This study suggests a model of a new set of evaluation criteria that will be used to measure the efficiency of real-world Ecommerce websites. Evaluation criteria include design, usability and performance for websites, the Data Envelopment Analysis (DEA) technique has been used to measure the websites efficiency. An efficient Web site is defined as a site that generates the most outputs, using t...

Today wireless sensor networks (WSNs) have gained grate popularity and are widely used in variety of areas due to their unique features. WSNs are deployed in an ad-hoc manner and consist of a large number of tiny sensor nodes. The sensor nodes communicate with each other through the routes established by the routing algorithms. Routing is considered as a challenging task in WSNs because it can ...

This paper proposes an extended data envelopment analysis (DEA) model for deriving eco-efficiency. In order to derive eco-efficiency, the proposed model utilizes the concepts of operational efficiency and environmental efficiency. Since DEA can separately measure operational efficiency and environmental efficiency, the treatment for constructing the unified indicator is required to ultimately e...

How to improve healthcare system’ efficiency has been highly concerned by Chinese government. The objectives of this paper are to establish production function of medical service and analyze returns to scale; to measure technical efficiency; and to highlight possible policy implications of the results for policy makers. Stochastic Frontier Approach (SFA) is employed in this paper based on data ...
