Health sector reforms are always linked to financial restraints. The relative low spending on healthcare by the majority of developing countries makes it even more crucial to plan the deployment of health services optimally. Many countries in the world have taken recourse to analyzing efficiency of the decision making units (DMU) in terms of inputs and outputs. A study from Ghana using this app...
the present study was an attempt to compare the effect of peer metalinguistic corrective feedback on elementary and intermediate efl learners speaking ability to see which level benefits more from this type of feedback. to this end, 117 female efl learners at grade 3, al-zahra high school in kermanshah, iran were non-randomly chosen. the homogeneity of the participants was attained through a pi...
abstract: sayyed mohammad tabatabaee is accounted as one of the effective persons in iran contemporaneoushistory and his role in the events of iran constitution revolution is inevitable. sayyed mohammad tabatabaee from the time of naser al din shah qajar and arrival to iran, informed of the advantages and the basis of constitution, was in the thought of making the iran rule as a constituti...
for several years, researchers in familiarity of efl teachers with post-method and its role in second and foreign language learners’ productions have pointed out that the opportunity to plan for a task generally develops language learners’ development (ellis, 2005). it is important to mention that the critical varies in language teaching was shown is the disappearances of the concept of method ...
The measurement of RTS amounts measures a relationship between inputs and outputs in a production structure. There are many different ways to calculate RTS in primal or dual space. But in more realistic cases, governments usually intervene on DMU’s behavior as regulatory agency, this clearly represent a set of limitations and restrictions on behaviors of DMUs, So very few decisions in DMUs are ...
The Trade Offs approach is an advanced tool for the improvement of the discrimination of Data Envelopment Analysis (DEA) models, Meta Malmquist Index was defined by Maria Portella and et. al (2008). In this paper we compute the Meta Malmquist Index in Trade Offs model in DEA and we compare, obtaining results, of Meta Malmquist Index in different models of DEA, Variable Return to Scale (VRS), Co...
performance evaluation in regular periods is one of the ways in which organizations can evaluate their performance as well as weak and strong points unifiedly and precisely. these days, mathematical models are also used to evaluate the efficiency and productivity of various units. these units are a collection of education, research and service activities as input and output factors an...
The value of the SU(3) coupling constant is estimated in the framework of the scale-relativistic minimal standard model. It is evolved, thanks to its renormalization group equation, from the GUT scale (which is identified with the Planck mass in scale relativity) where its value is conjectured to be 1/4π, to the Z boson scale, where its value is predicted to be 0.115. We also discuss the emerge...
We determine the radial excitation energy (2S-1S splitting)in the Upsilon spectrum using NRQCD b quarks on MILC configurations. We have statistical fitting errors of around 1% across a range of lattice spacing values using random wall sources, and this allows us to give improved determinations of the physical value of the heavy quark potential parameter r1. We also show improved results for the...
