The drivers of human capital engagement development are the factors influencing the processes, events, actions, and images that produce distinct results and consequences for the concept of engagement. The purpose of this study was to identify and categorize the drivers of development of human capital commitment and the views of human resource experts about the drivers of human capital commitment. To this end, the Q methodology was employed. First, the related literature and research background were reviewed and then, based on the documents, interviews and questionnaires from 12 experts, the phrase Q (49 phrases) was formed. In the next step, human resources and academic experts were asked to categorize the Q statements on the agreed-upon, opposite, and abstracted axes in the form of a six-choice spectrum of 6+ to -6. Then, based on the inferential statistics (factor analysis) using SPSS software, the data were analyzed and categorized into different mental patterns, and finally, three mental patterns were identified. Based on the results, it can be stated that the Q statements obtained are capable and comprehensive. Therefore, it has an accepted and approved narrative. In this study, re-test was used to confirm the reliability. In this way, at least 20% of the sample subjects, that is, three people (12 experts in total) were tested twice, and the correlation coefficient obtained was 82% (0.82), which indicates a high level of reliability. The mentalities obtained based on the order of importance are: first pattern: leadership and personal and identity development; third pattern: structural, process and procedural; and second pattern: management and organizational resources.

Earned Value Management (EVM) is known as an efficient and well-known tool for project management. Examining various sources, it was observed that although the EVM analytical model has introduced good indicators for measuring project progress, it is weak in estimating the final cost of the project and does not predict the process of cost change and project efficiency. On the other hand, nothing has been done so far to use system dynamics in EVM.Therefore, considering the capacity of system dynamics in modeling complex systems and setting parameters dynamically based on model variables, the main problem of modeling research is the value model obtained by simulating system dynamics. The dynamic hypothesis of the research was that there are dynamics between the main indicators of EVM. Identifying these dynamics and the way they affect each other can lead to estimating the process of changing costs and project efficiency by the end of the project.Through presenting the causal loop diagram and the stack flow diagram of the proposed model, the variables were determined and after simulation, the model was validated by performing various tests and different policy scenarios were presented.The comparison of the results of the research simulation model with the results of the EVM analytical model revealed that there is a slight difference between the results and the efficiency. The main contribution of the research is the creation of a simulation model based on system dynamics as the core of the simulation to estimate the trend and the final amount of efficiency and cost of the project, which can be part of a more comprehensive simulation model.This can be used to determine the impact of various project management functions on improving project efficiency, which is the main suggestion for further research.

In today's complex environment, the success of organizations requires the acquisition of competitive advantage; the benefits of intra-organizational characteristics effectively determine the competitive success of an organization.  Knowledge-based organizations, which play an important role in generating wealth and added value in a society, must keep pace with emerging changes in the new environment of the organization and strive to gain a competitive advantage in this competitive environment.  In the present study, the effect of intra-organizational characteristics on competitive advantage with the mediating role of entrepreneurial marketing in knowledge-based organizations active in Lorestan Science and Technology Park has been investigated.  The research method in this study is descriptive-survey and applied. The intended population was 120 experts of knowledge-based organizations active in Lorestan Science and Technology Park from among whom 92 experts were recruited through random sampling based on Morgan Table.  The data were collected using a standard questionnaire whose reliability was measured by Cronbach's alpha and its combined reliability and validity were measured by convergent method.  Structural equation modeling approach and Smart PLS software were used to analyze the data.  The results indicate that the characteristics within the organization (cooperation competence, administrative mechanism, organizational support, planning flexibility, planning time) both directly and indirectly, through entrepreneurial marketing, affect competitive advantage.

Today, productivity plays an important role in the economic development of countries. Infact, attention to productivity has gone beyond a choice; it has become a necessity. This study aims to identify the antecedents of organizational productivity based on the theory of new institutionalism. This research is developmental in terms of purpose. For this purpose, after searching the databases, in the period between 1998 to 2022, 671 articles in the field of productivity were evaluated and finally 65 articles were purposefully selected and analyzed. Based on the final research framework, organizational productivity antecedents based on the new institutionalist theory were classified into two main categories and eight sub-categories. The main categories resulting from the research results are: inter organizational antecedents and institutional antecedents. Interorganizational antecedents include five sub-categories of leadership and productivity management, organizational strategy and policy towards productivity, employees, organizational resources and organizational processes, and institutional antecedents include three sub-categories of legal / mandatory requirements, normative requirements and imitation / professional requirements. The obtained framework can be used for strategic planning in the field of organizational productivity.

The purpose of this study was to present a model of competitive capabilities considering social capital and buyer- supplier relationships. In terms of purpose, it is developmental-applied and in terms of nature, descriptive-analytical and regarding method, a mixed method study. The study population included the academic and industrial experts active in the elevator and escalator industry. To recruit the sample, purposeful and theoretical saturation sampling methods were used in which the researchers reached a saturation point after conducting 18 interviews. Semi-structured qualitative interviews were used to collect the data in the qualitative section and questionnaires were used for the quantitative section. To analyze the data, content analysis and interpretive structural equations were employed. The final obtained model reveals that the social capital variable has three comprehensive themes, 15 organizing themes and 49 basic themes, the buyer-supplier relationship risk has seven organizing themes and 28basic themes, and the competitive capabilities include nine organizing themes and 32 basic themes. Also, the results of the interpretive structural equation method show a six-level model.

The purpose of the current study was to design a paradigm model in order to establish idiosyncratic deals within private companies of Iran. In this research, a qualitative method based on the grounded theory was utilized. Semi-structured interviews and Strauss and Corbin data analysis were conducted to gather the data. Sampling was carried out using a theoretical sampling approach, and purposive-judgmental and snowball sampling techniques. After analyzing the results of the interviews with 19 professors and experts within private companies, in the process of open, axial, and selective coding, an idiosyncratic deals paradigm model was presented with 6 topics and 28 concepts. Based on the results, the casual factors influencing idiosyncratic deals within private companies are as follows: “hierarchical structures”, “motivation and collaboration”, “wage payment systems”, “resilience”, “behavior and task-oriented leadership style”, “employment limitations”, “lack of satisfaction among employees”, and “unwillingness to change”, the”, “strategic vision of the company”, and the intervening conditions are “managers’ support”, “negotiation power”, “management personal traits”, “leader-member exchanges”, “Adhocracy system within the company”, “meritocracy strategies”, “increased employees’ bargaining power”, “flexible work environment”, “providing novel ICT platforms”, “structural changes”, “improving service compensation system”, “decentralization”, “psychological empowerment”, and “holistic communication”. Moreover, establishing idiosyncratic deals can have “personal consequences” as well as “organizational consequences”.

Education plays a fundamental role in institutionalizing sustainable development. This research, which is a descriptive survey, seeks to identify the factors involved in sustainable development decision-making and the degree of deviation and the optimal situation in education policy. To ensure the validity of the questionnaire, in the first stage, the ambiguous points were clarified consulting the experts and in the second stage, using SPSS and the results of confirmatory factor analysis, those questions whose factor loadings had an effect on the fit of the model, were keep in the measurement model. Also, regarding convergent validity, Smart PLS was performed and the value of factors was greater than 0.4 which indicates acceptable validity. To measure reliability, both Cronbach's alpha and combined reliability test (CR) were used and in both cases, the value was higher than 0.7, indicating acceptable reliability. A combination of sampling methods, including available, purposive, snowball, and theoretical samplings was used. The statistical population consisted of all education experts and policymakers and the sample size was 70. Ten of the participants were selected as a qualitative sample for in-depth interviews and 60 people were selected as a quantitative sample. Finally, based on the output of PLS, the ranking of responsibility, future orientation, system orientation, practical skills, and individual participation, respectively, were identified as the decision-making factors of sustainable development in education policy, and it was found that there is a gap about one unit between the current and the desired situation in this regard.

Today, with the change in the competitive environment, successful countries are those with more knowledge, and knowledge management and knowledge-based human resource activities in organizations, especially in knowledge-based companies, which are the basis for the integration of science, technology and wealth, has become particularly important. Therefore, the present applied research was conducted to investigate the impact of knowledge management and human resource management activities on innovation using a descriptive survey research method. The statistical population was the employees of companies located in the growth and technology centers, from among whom, using Cochran's formula, 120 answered the questionnaire. The reliability of the questionnaire was confirmed with a combined reliability of more than 0.6 and a Cronbach's alpha coefficient of 0.892. Its validity was also confirmed through content validity and convergent validity with the mean variance criterion of structures which was more than 0.4. Finally, the conceptual model of the research was fitted using the structural equation model in PLS software.The results showed that various factors in the subset of knowledge management including supervisory actions, knowledge-based service compensation, learning mechanism and information technology measures affect innovation whereas the significance of the impact of factors such as knowledge protection, strategic management of knowledge and competence, knowledge-based employment, knowledge-based education and development, knowledge-based performance evaluation and work organization on innovation was not confirmed.

Handmade carpet industry is one of the most powerful internal industries which could not repeat the success it had in the past years at a global scale despite its high potential. One of the reasons can be lack of attention to productivity and the related affecting factors. Therefore, in the current research, a model was presented to measure the impact of marketing on the productivity of carpet industry in Iran. The statistical population included two different parts of carpet industry experts (10 experts) and the managers at different levels of Iran National Carpet Center and the Ministry of Industry, Mine and Trade from among whom 203 ones were selected based on Cochran sampling formula. First, reviewing the theories and frameworks about market orientation and productivity and benefiting the views of handmade carpet industry experts, a preliminary model was extracted. Then, through continuously applying structural equation model in LISREL software environment, the extracted model was tested and finally, the impact of market orientation including customer orientation (customer satisfaction, customer loyalty and customer capital), market situation (rival orientation and market intelligence) and inter functional coordination (flexibility, knowledge sharing and cooperation) on productivity (including market effectiveness and market intensity) was proved. It was also found that the influence of customer orientation on productivity was more than other dimensions.
