Content validity, the extent to which a measurement reflects the specific intended domain of content, is a basic type of validity for a valid measurement. It has usually been examined using qualitative methods and has not been given as much attention as the other psychometric properties such as internal consistency reliability, indicator reliability and construct validity in the IS field. In th...

The purpose of this study was to examine the effects of social cues in self-presentations and the congruence of other-generated comments with the self-presentation in people's evaluations of a profile owner. A 2 (level of social cues: high vs. low) × 2 (congruent vs. incongruent) × 2 (order) × 2 (multiple messages) mixed-subject experiment was conducted with 104 college students. The results sh...

In this paper we present a unique approach to personal identification which utilized finger surface features as a biometric identifier. Finger surface features are extracted from dense range images of an individual’s hand. The shape index (a curvature-based surface representation) is used to represent the surfaces of the index, middle, and ring fingers of an individual. This representation is u...

In this paper, we investigate the use of jitter estimation over short time intervals (short-term jitter) for voice pathology detection in the case of running or continuous speech. Short-term jitter estimations are provided by the spectral jitter estimator (SJE), which is based on a mathematical description of the jitter phenomenon. The SJE has been shown to be robust against errors in pitch per...

objectives: the present research aims to prepare an iranian police job satisfaction inventory (ipjsi) by using confirmative factor analysis as well as to evaluate the validity and reliability of it. method: a group consisting of 2933 iranian police employees chosen by stratified random sampling method from a number of police departments throughout the country completed the ipjs inventories. val...

Streamflow forecasting has an important role in water resource management (e.g. flood control, drought management, reservoir design, etc.). In this paper, the application of Adaptive Neuro Fuzzy Inference System (ANFIS) is used for long-term streamflow forecasting (monthly, seasonal) and moreover, cross-validation method (K-fold) is investigated to evaluate test-training data in the model.Then,...

Background: Logistic discriminant method was applied to differentiate malignant from benign in a group of patients with proved breast lesions on the basis of ultrasonic parameters. Materials and Methods: Our database include 273 patients' ultrasonographic pictures consisting of 14 quantitative variables. The measured variables were ultrasound propagation velocity, acoustic impedence and attenua...
