Kingston (J Comb Theory (A) 20:357–363, 1976) and Anderson (J Comb Theory (A) 23:363, 1977) show that the probability that a given contestant wins a bestof-2k+1 series of asymmetric, zero-sum, binary-outcome games is, for a large class of assignment rules, independent of which contestant is assigned the advantageous role in each component game. We design a laboratory experiment to test this hyp...
Recently some results have been presented which show that certain kinds of deterministic descriptions and indeterministic descriptions are observationally equivalent (Werndl 2009a, Werndl 2011). These results prompt interesting philosophical questions, such as what exactly they show or whether the deterministic or indeterministic description is preferable. There is hardly any philosophical disc...
Drug utilization evaluation (DUE) is an effective program to identify variability in drug use and to support interventions that will improve patient outcomes. The appropriate use of enoxaparin, a low molecular weight heparin (LMWH), which is widely used as curative or preventive treatment of thromboembolic disorders was assessed in the study. A prospective DUE was carried out at Masih Daneshvar...

Background and Objective: Studies in the health sciences is comprised of observational and intervention. A major part of health sciences research has been allocated to the observational studies. Designing and doing studies based on scientific guidelines that include the entire process, leads to studies validation and also results can be generalized to the community. Thus, for standardizing ...
conclusions endocarditis is an important disease with a high mortality rate if not treated appropriately. therefore, these patients need more attention. in echocardiography, vegetation and complications of ie such as abscess and paravalvular leakage can be detected. results we studied 35 patients, 45% male and 55% female with a mean age of 56.36 ± 12.44 years. fever (80%) and chills (65.7%) wer...
drug utilization evaluation (due) is an effective program to identify variability in drug use and to support interventions that will improve patient outcomes. the appropriate use of enoxaparin, a low molecular weight heparin (lmwh), which is widely used as curative or preventive treatment of thromboembolic disorders was assessed in the study. a prospective due was carried out at masih daneshvar...
chemotherapy medication errors may lead to potentially harmful consequences while most of them could be preventable. this study aims to determine the incidence and type of drug handling and administration errors among the nurses and to identify possible contributing factors. setting of the study was a teaching hospital affiliated to shahid beheshti university of medical sciences, tehran, iran. ...
We present a theory of environmental bisimilarity for the delimited-control operators shift and reset. We consider two different notions of contextual equivalence: one that does not require the presence of a top-level control delimiter when executing tested terms, and another one, fully compatible with the original CPS semantics of shift and reset, that does. For each of them, we develop sound ...
This article focuses on three themes concerning determinism and indeterminism. The first theme is observational equivalence between deterministic and indeterministic models. Here I discuss several results about observational equivalence and present an argument on how to choose between deterministic and indeterministic models involving indirect evidence. The second theme is whether Newtonian phy...
