Due to the growing number of new media, the number of digital citizens in society is increasing day by day. A digital citizen is a citizen who has the ability to use the online services provided by the government of each country to the best of his ability. The purpose of this study was to investigate the validity and reliability of digital citizenship scale in Birjand city. The statistical population of this study was all individuals aged 18 years and older in Birjand city, of which 384 were selected by multi-stage cluster sampling. The instrument used in this research is a digital citizen questionnaire, Chui, Glassman and Kristol (2017). Content validity of the Persian version was verified according to the opinion of the experts. Factor structure of digital citizenship questionnaire was investigated using both exploratory factor analysis and confirmatory factor analysis. The exploratory factor analysis showed that 4 substances have high yields in more than one factor; these materials were eliminated, and finally the final model included four factors; Internet political activity, technological skills, critical and local-global awareness. It came out with 22 substances. For reliability of this tool, Cronbach's alpha coefficient was used, which coefficient for its components was 0.79- 0.99. Given that the validity and reliability indicators of the Persian version of the Digital Citizen scale were all favorable, it can be used as a valid and reliable tool to identify digital citizens.

Abstract The present study aimed to examine the validity, reliability and factor structure of the Profile of Emotional Competence (PEC) among Iranian students. To this end 518 high school female students were selected in 2019 academic year using cluster sampling method and they completed the profile of emotional competence (Brasseur, Grégoire, Bourdu, & Mikolajczak, 2013), cultural competence Questionnaire (Central Vancouver Island Multicultural Society, 2007), and satisfaction with life scale (Diener, Emmons, Larsen, & Griffin, 1985). To investigate validity, confirmatory factor analysis and convergent validity were used. The findings of confirmatory factor analysis confirmed two-factor structure of the questionnaire and yielded two factors named as intra emotional competence and inter emotional competence. The correlation coefficients of the questionnaire scores with life satisfaction and cultural competence were 0.30 and 0.90 respectively. These results showed the convergent validity of the scale. To assess the reliability the questionnaire, Cronbach’s alpha was used. The Cronbach’s alpha coefficient was in satisfactory level for each factor (α = 0.80 for intra emotional competence, and α = 0.78 for inter emotional competence), and the total score of the scale (α = 0.92). The findings suggest that the profile of emotional competence is a reliable and valid instrument for assessing emotional competence of Iranian high school students and can be used as a suitable instrument in psychological research.

In the present study, the supplier selection problem from a new perspective is formulated and solved. For this purpose, minimizing cost and minimizing delivery time and maximizing reliability are considered as objectives of the problem. The purchasing cost in discounted status, the order cost, the transportation cost, the shortage cost and the carrying cost, the components forming the cost objective function. In this research, the design of reliability in parallel systems is benchmarked for supplier selection, so that the supplier's set is considered as a system and each supplier as a component. After mathematical modeling of the problem, the objective functions are described as fuzzy goals and a fuzzy decision approach has been used to rewrite the proposed three-objective model as a single-objective model. The production of a final solution rather than a set of Pareto's solutions is one of the advantages of the proposed method, which prevents decision-making confusion. In order to describe the function and potential application of the proposed method, the supplier selection problem with the actual data was solved. Manuscript profile

A desirable software application should be able to provide the quality attributes required by the system, as well as the functional requirements. Software architecture styles have a significant effect on the quality attributes of the designed software as well as its specification and decomposition.) The quantity evaluation and analysis of this effectiveness rate result in the selection of the most appropriate style for designing the architecture. In this paper, a method based on the Colored Petri Net is proposed to quantitatively evaluate three candidate attributes of the software architectural styles called the quality attributes, performance, reliability, and security in three candidate styles named shared-data, object-oriented, and pipe-and-filter software architectural styles. This method has not limitations of the previous-ones in evaluating the quality attributes. In this method, the candidate styles are firstly modeled by using the Colored Petri Net; then, considering the evaluation rules, CPN tools are used to analyze the networks and calculate the exact value of the candidate attributes. At the end, the best candidate style is chosen for implementation through ranking the styles in terms of the satisfaction level of the candidate quality attributes. To present a practical representation using the proposed methodology, the ATM system has been chosen as a case study. Manuscript profile

Network-on-chip is a router-based paradigm that determines the path of packet passing from the source to destination by a routing pattern through simplified protocols of the public data communication network. Sometimes, it is impossible to send packets from source to destination due to the communication problems caused by network elements in NoC such as routers and faulty links. In most cases, fault-tolerant algorithms select a reliable path using definite criteria. Therefore, in this paper, a reliable path is selected using a multi-criteria decision making technique through an adaptive approach according to the density status received from the adjacent nodes along with the path length so that when a failure occurs, a reliable path with similar QoS features is replaced by rating different paths among network nodes. The weight path selection strategy in NoCs to detect the minimal output port and multi-criteria decision making approach with VIKOR method has improvement over the basic routing algorithm in terms of delay and throughput. The algorithm hardware overhead has a reasonably low cost that maintains scalability for large scale On-Chip networks implementations. Manuscript profile

The aim of this study was to investigate the validity, reliability and factor structure of the Female Sexual Well-Being Scale in Iranian married women. For this purpose, a sample of 297 married women (with a mean age of 33.7 years and an age range of 24 to 45 years) was selected by simple random sampling. The Psychological Well-Being Questionnaire (Reef, 1995) and Women's Sexual Well-Being Scale (Rosen et al., 2009) were completed by the sample group. The validity of this scale was assessed using exploratory and confirmatory factor analysis methods, convergent and simultaneous validity. The reliability of the scale was evaluated by two methods of Cronbach's alpha and halving. The results of factor analysis using principal component method and varimax rotation showed that this scale consists of 4 factors with the titles of interpersonal relationships, cognitive-emotional domain, physical stimulation and orgasm satisfaction, which is more than 66% of the variance. They explain the whole. The convergent validity of this scale indicated a satisfactory correlation between the dimensions of the female sexual well-being scale and the total score. To determine the simultaneous validity of the scale, the correlation between the dimensions of the female sexual well-being scale and the psychological well-being scale was used, which indicated a favorable correlation (p <0.001). Cronbach's alpha and halving coefficients for the whole scale and its dimensions ranged from 0.63 to 0.82. The final result is that the Persian form of the Women's Sexual Welfare Scale has good validity and reliability in Iranian society and can be used in research, educational and clinical situations.

Considering the fact that customer loyalty is regarded as one of the most important concerns of hotel managers, this study sought to investigate the influence of human resources management activities on customer loyalty using a multi-level approach. The statistical population of the study comprised of managers, staff, and customers of four-star and five-star hotels in Mashhad. Moreover, the statistical sample size of the research at the organization level consisted of thirty-four, one-hundred and forty, two-hundred and forty managers, staff, and customers at organizational, staff, and customer levels, respectively. On the other hand, Sam’s 12-item questionnaire (2008) and the 17-item questionnaire developed by Al-Rafiei et al. (2013) were used to measure the human resources management activities and the staff’s satisfaction and loyalty, respectively, whose validity and reliability was tested using the Content validity method and Cronbach's alpha, respectively. Finally, HLM 7.02 and the SPSS software were used to analyse the collected data. The results proved the positive influence of human resources management activities on the staff’s satisfaction and loyalty, and in turn, on the satisfaction and loyalty of the customers. Therefore, it could be argued that hotel managers can increase the loyalty of their customers by emphasizing human resource management activities and improving their staff’s satisfaction and loyalty, which would increase the profitability of hotels in the long term by reducing marketing costs.

The validation performance is obligatory to ensure the software reliability by determining the characteristics of an implemented software system. To ensure the reliability of software, not only detecting and solving occurred faults but also predicting the future fault is required. It is performed before any actual testing phase initiates. As a result, various works on software fault prediction have been done. In this paper presents, we present a software fault prediction model where different data transformation methods are applied with Poisson fault count data. For data pre-processing from Poisson data to Gaussian data, Box-Cox power transformation (Box-Cox_T), Yeo-Johnson power transformation (Yeo-Johnson_T), and Anscombe transformation (Anscombe_T) are used here. And then, to predict long-term software fault prediction, linear regression is applied. Linear regression shows the linear relationship between the dependent and independent variable correspondingly relative error and testing days. For synthesis analysis, three real software fault count datasets are used, where we compare the proposed approach with Naïve gauss, exponential smoothing time series forecasting model, and conventional method software reliability growth models (SRGMs) in terms of data transformation (With_T) and non-data transformation (Non_T). Our datasets contain days and cumulative software faults represented in (62, 133), (181, 225), and (114, 189) formats, respectively. Box-Cox power transformation with linear regression (L_Box-Cox_T) method, has outperformed all other methods with regard to average relative error from the short to long term. Manuscript profile

The present study was conducted with the aim of introducing and investigating the psychometric properties of the Persian version of the Premenstrual Coping Measure (PMCM (. This research, in terms of method, is a descriptive-cross-sectional-correlation study that its population included all the female students in Salman Farsi University of Kazeroon in the academic year of 2021-2022. The sample group included 303 female students who were selected by the available sampling method and actually participated in the present research by answering the online questionnaire. This questionnaire, in addition to the Persian version of the PMCM, included the Premenstrual Symptoms Screening Tool, Multidimensional Health Locus of Control-C, and the Menstrual Attitude Questionnaire. Research data has been analyzed in SPSS-22, AMOS-22 and JASP-09. The results of exploratory and confirmatory factor analysis have confirmed the existence of a five-factor structure in the scores obtained from the Persian version of the premenstrual coping strategies scale. The values of Cronbach’s alpha and McDonald's omega also showed good internal consistency in the total scale and its five subscales. The correlation coefficients between PMCM, and three other research tools, while confirming the construct validity, suggested a close relationship between premenstrual strategies and an internal locus control for health and an attitude based on expectation and prediction of menstruation.

The collected data was randomly divided into two equal parts (n=285) for exploratory and confirmatory factor analysis. The results obtained from exploratory factor analysis with principal components and oblimin rotation showed a two-factor structure which were named certainty and uncertainty. The amount of eigenvalue for certainty and uncertainty were 2.04 and 1.39, respectively. Also, the first factor (certainty) and the second factor (uncertainty) explained 25.56 and 13.42 percent of the variance of scores. The results of confirmatory factor analysis confirmed the bifactor structure (χ2=76.12, df=48, P=0.01; GFI=0.98; AGFI=0.96; CFI=0.98; RMSEA=0.03). Cronbach's alpha coefficients for factors were 0.78 and 0.76, respectively. In addition, the retest results for certainty and uncertainty factors were 0.76 and 0.73, respectively, and the composite reliability index for these two factors were 0.88 and 0.86, respectively. The results of Pearson's correlation to examine convergent validity with attachment styles and Emotion regulation difficulty showed that there is a significant relationship between these variables at the 0.01 level. Also, using the Fornell and Locker index, the discriminant validity of RFQ was confirmed. According to the obtained results, the validity and reliability of the Persian version of RFQ can be confirmed.</p> Manuscript profile
