This paper presents, EtE monitor, a novel approach to measuring web site performance. Our system passively collects packet traces from a server site to determine service performance characteristics. We introduce a two-pass heuristic method and a statistical ltering mechanism to accurately reconstruct di erent client page accesses and to measure performance characteristics integrated across all ...

Burnout of nurses at university hospitals was analyzed in relation to their personality characteristics and coping behaviors. A self-administered questionnaire regarding burnout (the Copenhagen Burnout Inventory), work-related stressors (the Nursing Job Stressor Scale), personality characteristics (Short-Form Eysenck Personality Questionnaire-Revised), and coping behaviors (the short Japanese v...

OBJECTIVE Sociodemographic and psychopathological characteristics as well as treatment approaches to patients at an outpatient clinic for drug addicts are described. METHODS Descriptive study based on randomly sampled medical charts and registration forms of subjects presenting for treatment from 1986 to 1993. RESULTS The sample was made up predominantly of young white unmarried men, with l...

A large literature concludes that Big N auditors provide higher audit quality than non-Big N auditors. An unresolved question, however, is whether self-selection drives this “Big N effect.” Most recently, a high profile study concludes that Propensity Score Matching (PSM) on client characteristics causes the Big N effect to disappear. We conjecture that this finding may be affected by PSM’s inh...

This paper documents how information technology (IT) impacts audit efforts. Using cross-sectional data on audit engagements for the 100 largest clients of an office of a leading international public accounting firm, it empirically evaluates the impact of the clients’ IT choices on their auditor’s audit effort. The results indicate that other things being equal, the higher level of automation or...

In the theory of traffic flows the main characteristics are: intensity, speed, and density.  They make it possible to use hydrodynamic models. In connection with the development of modern highways and road networks, traffic flows behavior is becoming more and more complex and diverse. In particular, the B.Kerner studies have shown that the laminar solution of hydrodynamic models is poorly corre...

This paper proposes a novel approach for the implementation of simulation scenarios, providing a client entity for cloud computing systems. The client entity allows the creation of scenarios in which the client behavior has an influence on the simulation, making the results more realistic. The proposed client entity is based on several characteristics that affect the performance of a cloud comp...
