Paper provides a method for solving the reverse Monge-Kantorovich transport problem (TP). It allows to accumulate positive decision-taking experience made by decision-taker in situations that can be presented in the form of TP. The initial data for the solution of the inverse TP is the information on orders, inventories and effective decisions take by decision-taker. The result of solving the i...

Recent algorithms provide powerful solutions to the problem of determining cost-minimizing (or revenue-maximizing) allocations of items in combinatorial auctions. However, in many settings, criteria other than cost (e.g., the number of winners, the delivery date of items, etc.) are also relevant in judging the quality of an allocation. Furthermore, the bid taker is usually uncertain about her p...

With computerized testing, it is possible to record both the responses of test takers to test questions (i.e., items) and the amount of time spent by a test taker in responding to each question. Various models have been proposed that take into account both test-taker ability and working speed, with the many models assuming a constant working speed throughout the test. The constant working speed...

Multiple Choice tests are utilized widely in educational assessment because of their objectivity, ease of scoring, and reliability. This study aimed to compare IF and ID of MC vocabulary test items and attempted to find whether these indices are affected by the number of options. To this end, four 20 item stem equivalent vocabulary tests (3-, 4-, 5-, and 6-option MC) were administered to 194 (1...

Emotion Perception and Reactions to Tests: Affective Influences on Test Performance by Pablo Cruz The two studies presented here examine the impact of non-cognitive factors on test reactions and test performance. It is well-established that test anxiety can adversely affect test outcomes, particularly in high-stakes testing situations, but what is less well understood are the moderators that ca...

This article discusses metaphor annotation in a corpus of argumentative essays written by test-takers during a standardized examination for graduate school admission. The quality of argumentation being the focus of the project, we developed a metaphor annotation protocol that targets metaphors that are relevant for the writer’s arguments. The reliability of the protocol is κ=0.58, on a set of 1...
