BACKGROUND Given the importance of high-quality healthy food for humans, contamination control is the most important concern for healthy staff. AIM To determine the attitudes of students at Islamic Azad University (Tehran Medical Branch) toward food safety. METHODS This cross-sectional and analytic-descriptive study was conducted on 326 students of Azad University of Medical Sciences in 201...

This study was conducted to evaluate recipients' perception of service quality, satisfaction, and behavioral intention in home delivered meals program in the US. Out of 398 questionnaires, 265 (66.6%) were collected, and 209 questionnaires (52.5%) were used for the statistical analysis. A Confirmatory Factor Analysis (CFA) with a maximum likelihood was first conducted to estimate the measuremen...

The purpose of this paper was to evaluate the psychometric properties of a stage-specific self-efficacy scale for physical activity with classical test theory (CTT), confirmatory factor analysis (CFA) and item response modeling (IRM). Women who enrolled in the Women On The Move study completed a 20-item stage-specific self-efficacy scale developed for this study [n=226, 51.1% African-American a...

BACKGROUND This paper seeks to analyse the psychometric and structural properties of the Multidimensional Pain Inventory (MPI) in a sample of temporomandibular disorder patients. METHODS The internal consistency of the scales was obtained. Confirmatory Factor Analysis was carried out to test the MPI structure section by section in a sample of 114 temporomandibular disorder patients. RESULTS...

This paper provides the results of an applied research of forests engineers connected to their risk of mental stress occurrence in everyday work. This paper also has a component of a basic research, in which the adequacy and reliability of applied methodology in this kind of researches is examined. The mental stress induced risk is tested by usage of an e-mail survey which consists out of 23-pa...

BACKGROUND Validity and reliability of an urbanicity scale is of utmost importance in developing effective strategies to minimize adverse social and health consequences of increased urbanization. A number of urbanicity scales for the quantitative assessment of the "static" feature of an urban environment has been invented and validated by the original developers. However, their comparability an...

Client-Server systems cache data in client buffers to deliver good performance. Several efficient protocols have been proposed to maintain the coherence of the cached data. However, none of the protocols distinguish between index pages and data pages. We propose a new coherence protocol, called Relaxed Index Consistency, that exploits the inherent differences in the coherence and concurrency-co...

The analytic hierarchy process (AHP) is a structured technique for dealing with complex decisionmaking and is already used to solve many group decision problems. This paper used the CauchySchwarz inequality to improve the AHP algorithm that was developed by Escobar et al. (2004). They provided an upper bound for the group geometric consistency index in order to prove that the group geometric co...

The determination of examinee effort is an important component of a neuropsychological evaluation and relies heavily on the use of symptom validity tests (SVTs) such as the Test of Memory Malingering (TOMM) and the Word Memory Test (WMT). Diagnostic utility of SVTs varies. The sensitivity of traditional TOMM criteria to suboptimal effort is low. An index of response consistency across three tri...

In the calculation of economic aggregates it is often necessary to compute the value of these aggregates in some relevant subgroups as well as for the whole data. A method of calculation is said to be consistent in aggregation if it gives the same result regardless of whether it is applied directly to the whole data or to subaggregates calculated using the same method. The property has been wel...
