background: primary dysmenorrhoea without any specific pelvic disease is one of the common complaints in women`s medicine. the general purpose of this research is to define the effects of 12-week aquatic exercises on nonathletic girls’ primary dysmenorrhoea. materials and methods: this quasi-experimental was conducted on 40 nonathletic girls aged 18-25 years. data gathering tools were: evaluati...

Traditional super-efficiency data envelopment analysis (DEA) models rank efficient units under the assumption of constant returns to scale (CRS). However, infeasibility may occur in super-efficiency models under variable returns to scale (VRS). This paper proposes a modified VRS super-efficiency DEA model to deal with infeasibility by relaxing the convexity constraint 1, 0 1 n j j j λ = ≠ = ∑ t...

The type of noise annoyance scale and aspects of its presentation such as response format or location within a questionnaire and other contextual factors may affect self-reported noise annoyance. By means of a balanced experimental design, the effect of type of annoyance question and corresponding scale (5-point verbal vs. 11-point numerical ICBEN (International Commission on Biological Effects...

Likelihood ratios are increasingly being adopted to convey expert evaluative opinions to courts. In the absence of appropriate databases, many of these likelihood ratios will include verbal rather than numerical estimates of the support offered by the analysis. However evidence suggests that verbal formulations of uncertainty are a less effective form of communication than equivalent numerical ...

ABSTRACT BACKGROUND AND OBJECTIVES: It is possible that patients submitted to lumbar spine surgery present chronic pain and need a multidimensional assessment of postoperative due the variables influence pain. The objective this study was evaluate correlation between uni scales for assessment. METHODS: Longitudinal observational carried out in inpatient units an orthopedic reference hospital Sa...

an experimental database is compiled in order to fingerprint the scales formed over the hot surfaces of heat exchangers, in cooling water systems or other systems with similar chemistry. to collect these data, a dynamic simulating pilot plant was designed with considerable application flexibility among which simultaneous flow of water with different velocity and heat fluxes to three simulating ...

this paper proposes an alternative approach for efficiency analysis when a set of dmus uses interval scale variables in the productive process. to test the influence of these variables, we present a general approach of deriving dea models to deal with the variables. we investigate a number of performance measures with unrestricted-in-sign interval and/or interval scale variables.

Unlike teacher beliefs, there has been a dearth of study regarding EFL learner beliefs. The reason can be that Horwitz (1987) and the existing literature has predominantly been in an ESL context. The present study reports the development and validation of a scale to measure the learner beliefs about language learning in Iranian EFL contexts. Using a combination of verbal creativity method, inte...
