In the business world today, intense competition among the firms forces them to operate under conditions of uncertainty which, in turn, gives rise to numerous risks that can negatively impact the supply chain and lower profitability and competitive advantage. Expansion and density of communication network in the supply chain, on the one hand, and inevitability of some disorders, on the other, underscore the importance of measuring and evaluating suppliers. Supplier resilience defined as less influenceability from and the capacity to quell disorders, hence, requires more rigorous scrutiny. The aim of the current research was thus to identify and level suppliers’ resilience criteria at Avrand's Industrial Group supply chain using a combination of Fuzzy Delphi (FDELPHI) and Interpretative Structural Modeling techniques. The results of the FDELPHI method showed that 16 of the 27 criteria extracted from the literature review were verified by the team of 10 experts. Further, the Interpretive Structural Modeling was employed to offer a hierarchical model of the verified criteria. The results revealed a five-level hierarchy of resilience criteria with the delay time criterion at the highest level and the most influenceable factor and financial strength criterion as the most influential factor placed at the lowest level.

The rapid spread of spirituality and religious beliefs in the new millennium has increased the importance of spirituality and its applications for governments, organizations and managers. One of the most significant issues in this regard is the role spirituality can play in promoting the workplace atmosphere. Thus, the aim of the present research was to design a model to assess the relationship between spirituality in workplace with human resource and organizational performance. To achieve the aim, the researchers first designed a conceptual model using relevant variables collected through a rich literature review and via exploratory factor analysis. Secondly, they examined the model using Structural Equation Modeling. The results of the questionnaires that were collected from a random sample of 217 workers at Allameh Tabataba'i University showed that trust in God, catering for human values of employees, fostering labor force creativity, felling a sense of meaningfulness of work and increasing organization productivity have the greatest impact on each of the latent variables of the model. Based on the values of CPR statistics, the set significant level and model fit indices, the research hypotheses were confirmed.

The purpose of this causal-correlational study was to investigate the causal relationship between organizational culture and organizational silence with human resource productivity with respect to mediating role of organizational citizenship behavior among the municipal employees in Zanjan. In this study, a sample of 180 municipal employees was randomly selected. The instruments used in this research included the Human Resources Productivity Inventory (Hersey & Goldsmith, 1999), Organizational Citizenship Questionnaire (Podesakoff et al., 1991), Organizational Culture Questionnaire (Denison, 2000) and Organizational Silence Questionnaire (Morrison & Milliken, 2000). The proposed model of the relationships among variables was tested using path analysis software (AMOS-22). The findings emerging from the study revealed that the proposed model of causal relationships among these variables was of an acceptable fit. That is, organizational culture was found directly and indirectly related with human resource productivity through organizational citizenship behavior. Organizational silence was also found related to human resource productivity via organizational citizenship behavior with.

The aim of this study was to evaluate the effect of comprehensive quality management on Green Productivity in Iran Casting Industries Company. A random sample of 115 employees from various executive and managerial sections was recruited 90 of who were selected to form the research sample based on Cochran formula, Morgan and Krejcie Table. The research data were normally distributed and thus were analyzed using Structural Equation Modelling and parametric tests. Further analysis confirmed omposite reliability, internal consistency and credibility of the data, as well as diagnostic validity at the level of structures. The positive values ​​in the index CV Com verified the suitable quality of the models. Ultimately, the GOF index of 0.207 was computed. According to literature, the three values ​​of 0.1, 0.25 and 0.36 are interpreted as weak, medium and strong, respectively; hence, the GOF index of 0.207 indicated a moderate fit of the model. Based on the findings from this research, comprehensive quality management has direct and positive impact on Green Productiviey.

The purpose of the present study was to investigate the effect of information technology (IT) governance and job alienation on counterproductive work behavior in automated professional public libraries and banks in West Azerbaijan. To serve the purpose, a descriptive correlational research method was employed in this applied study. The research sample comprised 132 librarians and 400 bank staff members who were randomly selected from the population of librarians and bank employees in the province based on Morgan Table. The research data was gleaned employing a researcher-made questionnaire the validity of which was confirmed by expert views and the reliability of which was explored based on the Cronbach Alpha coefficient. The collected data were analyzed using SPSS and PLS software. The results confirmed the research model in public libraries. Based on the findings, IT governance did not directly influence the counterproductive work behavior in public libraries, but the effect was justified via job alienation. However, IT governance was found to have both direct and indirect effects on job alienation and counterproductive work behavior in banks. Moreover, the findings indicated that IT governance had differential impacts on counterproductive work behavior in automated and non-automated organizations.

The primary aim of the present study was to provide a model for understanding the impact of supply chain integration on supply chain performance with the mediating role of competitiveness in pharmaceutical companies in Iran.

Adaptation to change and the pace of carrying out assignment were identified as the most influential and the most influenced factors, respectively.

Achieving success in an industrial cluster depends on avariety of variables. A fertile research soil in this regard seems to be investigation of the very concept of value from different perspectives. The aim of this study was thus to identify barriers to value creation in auto part industry of East Azarbaijan and to scrutinize them using ISMtechniqueThe research population comprised 220 managers of auto part manufacturing companies who were members of auto-part manufacturer forum of East Azarbaijan. A sample of 71 was further selected from the population based on Cochran's formula. Two questionnaires were distributed to glean the research data: one focused on identifying the value creation barriers and the other on pinpointing the inter-relationships among those barriers. Value creation barriers were identified via t-test analysis of the research data and the ISM technique was implemented in structuring the identified barriers. The findings emerging from the ISM analysis delineated "nonsufficient experience", "poor inter-personal communication" and "technological changes" as the most influential barriers, and "lack of innovative ideas", "low quality of manufacturing" and "routine thinking" identified as the most influenceable barriers to value creation in the auto part industry. The findings suggest that the barriers could be adequately overcome by promoting work relationships among the personnel, employing experienced experts and reinforcing research and development in monitoring new technologies in automotive industry.
