while the growth of mis investment and its influence is making mis evaluation ever more indispensable, little attention has been paid to assessing and communicating system effectiveness. this paper attempts to empirically assess the effectiveness of integrated human resource information system in iranian oil industry. as suggested by recent research, the widely accepted is success model is ba...

conclusions geographic accessibility of pharmacies at night and on holidays has to be addressed by provincial health policymakers. materials and methods the analysis was based on straight-line distance measurements. we considered 150, 300, 450, 600, and 750 m for pedestrians, and 1, 2, and 3 km for driving accessibility as the acceptable distances. we calculated the number and percentage of hou...

A rule-based object/task modelling approach for GIS's is proposed which is characterized by specifying database app lications in terms of localized domain knowledge representa tion and explicit control knowledge representation! and by utilizing complementaryly the techniques of database, logic and object—oriented programming to support inferencing and deductive quering.

aims: hospital information system may offer a way to increased self-care management. the aim of this study was to determine the patients’ informational needs for self-care management and evaluation of different his software according to these needs.  materials & methods: this descriptive cross-sectional study was done during 2011-2012 in kashan city, iran at two phases compiling the required in...

We consider a multi-source status update system, where each source generates packets according to Poisson process which are then served generally distributed service time. For this M/G/1/1 queueing model, we self-preemptive packet management policy and derive the moment generating functions (MGFs) of age information (AoI) peak AoI source. According policy, an arriving fresh preempts possible sa...

in this paper by use of mathematical modeling of an observer [14,15] the notion of relative information functional for relative dynamical systemson compact metric spaces is presented. we extract the information function ofan ergodic dynamical system (x,t) from the relative information of t fromthe view point of observer χx, where x denotes the base space of the system.we also generalize the inv...

purpose: libraries and information centers as information storage and retrieval systems can develop with the adoption of cybernetics rules. this paper discusses system dynamics, control, feedback, and other cybernetic concepts especially in information storage and retrieval systems. methodology: this study is a review intending to find what cybernetics and lis have in common especially in the f...
