Abstract
Purpose
The purpose of this paper is to examine how brand personality and brand equity affect intentions to revisit a city tourism destination.
Design/methodology/approach
Statistical population of this research consisted of those visitors who traveled to Pool city in Iran during Spring 2015. A structural equation model test with maximum likelihood estimation was performed to test the relationship among the research variables using 367 participants.
Findings
The empirical results from the structural model suggest that brand personality and brand equity positively influenced revisit intention. Furthermore, brand personality was a direct antecedent of brand equity.
Originality/value
An integrated model of brand personality, brand equity and revisit intention was tested in a tourism city in the context of a developing economy. The combination of a developing country context and the significance of destination brand enhance the contextual contribution of the paper.

In this study, the concept of organizational stupidity (OS) and different aspects of the OS is analyzed, and a conceptual model for the OS is proposed.
Abstract
Purpose
In this study, the concept of organizational stupidity (OS) and different aspects of the OS is analyzed, and a conceptual model for the OS is proposed.
Design/methodology/approach
The data for the OS study were collected by interviewing the employees of the Iran Revenue Agency (IRA), Isfahan Province Branch. The snowball method was used for sampling and data collection. The data collected from interviews are analyzed using MAXQDA (a software for qualitative data analysis).
Findings
After analyzing the data, a conceptual model for the OS is proposed using the grounded theory (GT). The proposed model contains all factors influencing the OS and the relationship among them. The accuracy of the proposed OS model is confirmed using structural validity, external validity, descriptive validity and interpretive validity. The reliability of the proposed OS model is approved using the Holstie, Miles and Huberman reliability equation. The proposed model shows the casual conditions, interfering factors, contextual factors and main phenomena leading to OS and predicts the strategies and consequences of the OS.
Originality/value
This model can be used to plan strategies for managing and reducing OS in organizations.

Abstract
Purpose
The purpose of this paper is to present a computational fluid dynamic simulation for the investigation of the particles segregation phenomenon in the gas–solid fluidized beds.
Design/methodology/approach
These particles have the same size and different densities. The k–ε model and multiphase particle-in-cell method have been utilized for modeling the turbulent fluid flow and solid particles behaviors, respectively. The coupled equations of the velocity and pressure have been solved by using a combination of SIMPLE and PISO algorithms. After validating the simulation, different mixing indices, with different calculation bases, have been investigated, and it has been found that the Lacey mixing index, which was defined based on statistical concepts, is suitable to investigate the segregation/mixing phenomena of this bed in different conditions. Finally, the effects of parameters such as velocity, particle density ratio, jetsam concentration, and initial arrangement on the segregation/mixing behaviors of the bed have been studied.
Findings
The results show that the increase in the superficial gas velocity decreases the mixing index to a minimum value and then increases this index in the beds with mixed initial condition, unlike the beds with separated initial condition. Moreover, an increase in the particle density ratio increases the minimum fluidization velocity of the bed, and also the amount of segregation, and increase in the jetsam concentration increases the value of the mixing index.
Originality/value
A computational fluid dynamics simulation has been presented for the particles segregation phenomenon in the gas–solid fluidized beds.
