A significant theme in data envelopment analysis (DEA) is the stability of returns to scale (RTS) classification of specific decision making unit (DMU) which is under observed production possibility set. In this study the observed DMUs are public postal operators (PPOs) in European Union member states and Serbia as a candidate country. We demonstrated a sensitivity analysis of the inefficient P...

As preferred provider organizations (PPOs) become the dominant model of managed health care in the private sector, policymakers have increasingly viewed PPOs as an attractive option for Medicare. In part to understand how PPOs might operate under the Medicare Program, CMS launched the Medicare PPO demonstration in January 2003. In this article, we examine how PPOs have operated so far under the...

This paper explores the potential of personalising health reminders to melanoma patients based on their personality (high vs low conscientiousness). We describe a study where we presented participants with a scenario with a fictional patient who has not performed a skin check for recurrent melanoma. The patient was described as either very conscientious, or very unconscientious. We asked partic...

In this paper, the effect of lightness on blackness preference of 216 black fabrics prepared by printing method is investigated. 18 observers including of 9 males and 9 females are asked to firstly rank order black fabrics with the same lightness values according to their preference. In the next step, observers are asked to define their blackness preference for blacks with different L values. R...

H. R. Blackwell (1952) investigated the influence of different psychophysical methods and procedures on detection thresholds. He found that the temporal two-interval forced-choice method (2-IFC) combined with feedback, blocked constant stimulus presentation with few different stimulus intensities, and highly trained observers resulted in the "best" threshold estimates. This recommendation is in...

A computational model of spatial relational reasoning implemented in the ACT-R cognitive architecture allows for the simulation of a wide range of behavioral data in the context of both determinate and indeterminate deductive spatial reasoning tasks. In that respect the presented study bridges the gap between results of previous work that investigated determinacy conditions separately. ACT-R’s ...
