The Validity and Reliability of the Persian Version of Nomophobia Questionnaire

Background: Nomophobia is the fear of being disconnected from one’s mobile phone, prevailing in modern area. To the best of our knowledge, no Persian psychometric scales are available for investigating nomophobia among Iranians. Therefore, we here aimed to translate and validate the Nomophobia Questionnaire (NMP-Q) for being used in Iran. Methods:The NMP-Q was translated from English to Persian using a classical “backward and forward” procedure. Exploratory factor analysis (EFA) was carried out to explore the underlying factor structure of the translated questionnaire. A principal component analysis (PCA) approach with varimax rotation was further performed. Findings: 425 volunteer students were included. Among them, 80.2% were 20-30 years old. Men and women constituted 187 (44.0%) and 238 (56.0%) of the participants, respectively. 100 (23.5%) of the subjects were medicine graduates. Using mobile phones for more than 5 years was noted in 215 (50.6%) subjects. Also, 422 (99.3%) subjects connected to the Internet via their cellphones. Regarding cellphone usage, 301 (70.8%) subjects used them less than 5 hours a day, 158 (37.2%) subjects checked their cellphones less than 10 times a day, and 92 (21.6%) subjects checked their cellphones every 20 minutes. Eigenvalues and the scree-plot supported a 3-factorial nature of the translated questionnaire. NMP-Q showed an overall Cronbach's alpha coefficient of 0.93 (the coefficients of 0.90, 0.77, and 0.71 for the three factors, respectively). The first, second, and third factors explained 26.30%, 20.84%, and 17.60% of the variance, respectively. The total score of NMP-Q correlated with the hours spent with mobile phones, the years of using them, and the age. Conclusion: Our findings showed that the Persian version of the NMP-Q was a valid and reliable tool for evaluating nomophobia among Iranians

Hybrid simulation of a structure to tsunami loading

A new hybrid simulation technique has been developed to assess the behavior of a structure under hydrodynamic loading. It integrates the computational fluid dynamics and structural hybrid simulation and couples the fluid loading and structure response at each simulation step. The conventional displacement-based and recently developed force-based hybrid simulation approaches are adopted in the structural analysis. The concept, procedure, and required components of the proposed hybrid simulation are introduced in this paper. The proposed hybrid simulation has been numerically and physically tested in case of a coastal building impacted by a tsunami wave. It is demonstrated that the force error in the displacement-based approach is significantly larger than that in the force-based approach. The force-based approach allows for a more realistic and reliable structural assessment under tsunami loading

The Role of Job Performance on Career Success and Self-esteem of Staff

Introduction: Human resources are the most valuable assets to any organisation, identifying factors that affect job performance of these resources has become increasingly important. Aim: To determine the relationship between self-esteem and success with job performance in the staff of the Shahrekord University of Medical Sciences (SKUMS) Headquarters, Shahrekord, Iran. Materials and Methods: This descriptive-analytical (correlational) study, based on structural equation modeling, was conducted in 2015. The study population included 240 of the staff of SKUMS Headquarters, Shahrekord, Iran. From these people, 86 were selected by simple random sampling. A questionnaire of demographic characteristics, Paterson job performance, Radsyp career success and Eysenck selfesteem questionnaire were used to evaluate the concepts of job performance, success and self-esteem. The data were analysed using Statistical Package for the Social Sciences (SPSS) version 23.0. Results: A total of 86 out of which 49 were female (57%) and 37 (43%) male, with a mean age of 39.85±7.6 (range 24-55) years. There was no significant relationship between demographic characteristics and job performance, career success and selfesteem. Self-esteem could be predicted positively and career success could be predicted negatively. Job performance and selfesteem had a significant positive correlation relationship (p<0.05). Conclusion: According to the direct relationship between job performance and self-esteem in this study, officials can improve job performance of staff through supporting them and reinforcing their self-esteem and thus providing career success

Prevalence of Obesity and Overweight and Its Associated Factors in Urban Adults from West Azerbaijan, Iran: The National Food and Nutritional Surveillance Program (NFNSP)

Background and Objectives: Globally, the prevalence of overweight/obesity is increasing at an alarming rate. According to the World Health Organization (WHO), about 1.9 billion adults worldwide are overweight, and of these, over 600 million are obese. The purpose of this study was to determine the prevalence of overweight and obesity in West Azerbaijan, Iran, in 2014. Materials and Methods: Data were collected as part of the National Food and Nutritional Surveillance Program (NFNSP). A total of 249 men and women aged 20&ndash;60 from West Azerbaijan were included in the survey conducted in 2014. Body height and weight were measured with light clothing and no footwear after overnight fasting. Results: Mean age of the participants was 38.5 &plusmn;7.8 yrs. Mean BMI was 28.0&plusmn;4.9 kg/m2 (men: 26.8&plusmn;4.2 vs. women: 29.0&plusmn;5.3, p<0.001). The prevalence of overweight and obesity was 36.5% (men: 38.6 % vs. women: 34.8%, p: 0.439) and 33.3% (men: 25.4 vs. women: 40.0 %, p: 0.016), respectively. Women were more likely to be overweight or obese than males (P=0.038). Multiple logistic regression revealed that gender (women vs. men) (OR, 2.05; CI, 1.15-3.65; p,0.014) and age (OR, 1.06; CI, 1.01-1.1; p,0.004) increased the risk of becoming overweight or obese. Women who were housewives were five times more at risk of becoming overweight or obese (OR: 4.93; CI: 1.9-12.3; p<0.001) even after adjusting for age and educational level. Conclusions: The high prevalence of weight problems in West Azerbaijan is a serious health concern, especially in women. The lifestyle of housewives is a potential risk factor for weight gain in women. Keywords: Obesity, Prevalence, Azerbaijan, Adult
