In this paper, an economic decisions-making model based on mathematics in order to optimize the costs of investment in accordance with innovative technology of human resources recruitment introduced and in the next section, the economic impact of the Internet recruitment technologies has been examined. In order to fulfill these demands classic economic order quantity model of have developed as cover unique cost of recruiting activities such as human resource management and coordination related to it. Therefore, using this method calculated the required minimum of recruitment level and consequently optimal investment in online recruitment technology has been resulted. The findings suggest that optimal investment costs near the minimum level of recruitment is rapidly increasing but the stunning developments in efficient technologies in recruitment system and lack of awareness of this minimum level of employment has caused total number of employees is more than the required minimum level. In this article, how to use this model in a research sample of online recruitment websites in Iran entitled “Iran recruitment” its potential as a tool for decision-making in the field of optimal investment for managers appeared.

Today, Information Technology services are considered as valuable resources in all areas. For making Information Technology Management Processes purposeful and efficient in different organizations &ndash as a competitive and strategic advantage (especially in organizations responsible for health care services) &ndash it is necessary to recognize the level of maturity of the organization and review its processes in the field of Information Technology Services. On the other hand, finding the relations between main components of maturity and Information Technology Standards are essential to make them functional. In this paper, in addition to recognizing the present IT Management Services and prioritize them we reviewed the gap between processes and compare them to provide related maturity levels for introducing a localized model in Information Technology Services maturity in organizations responsible for health care services. Therefore, with the help of health experts and professionals working in health organizations we categorized indicators in 10 management processes and 9 criteria related to it. In addition, we evaluated overlapping levels of maturity and ITIL management processes by using experts opinions that have a high percentage of consensus in the field of selecting criteria. The aim of deriving these indicators was creating a functional tool in health organizations and paying attention to its main differences with other methods in addition to inspiring from CMMI and entering effective components on Information Technology Infrastructures Standard (ITIL) framework according to functional views in Information Technology Management Services at the Tehran University of Medical Sciences. The present study can be recognized an applied research in accordance with its goal. In this research, a proposed instrument is used for gathering data (ITILRA questionnaire) from health care centers of Tehran University of Medical Sciences. The aim was determining the gap between current organizations management processes with an optimal one in the field of IT services (which are at different levels of maturity) with respect to the ITIL.V3 framework. For this reason, leveling joint processes between ITIL and CMMI and approving corresponding indicators at Information Technology Services Maturity Model levels were done and each criteria and processes were compared with ideal and standard situation separately. Then, we determined the highest and lowest differences rates and standard deviation for creating a localized maturity model based on ITIL. In management process, Service Desk has the most close and overlapped situation with ideal condition. In Configuration Management, the highest differences and gap was recognized, so, it should be closer to optimal condition. Service Desk belongs to Service Operations phase and it indicates the maturity level of the organization. As it was expected, it was in a very desirable condition. Configuration Management Process belongs to Translating Service Phase which stood in third place (predetermined processes) of maturity level in CMMI Model. It shows that improving maturity level of the organizations needs more efforts for reducing or omitting any gap between the current situation of the organization and a desirable condition. All these scores (by mean and standard deviation tests) obtained using SPSS software.

The aim of this study was to analyze the impact of social capital and organizational learning on organizational performance in Payame Noor University of Kermanshah province. It is a functional purpose study with descriptive – survey method. The statistical population includes 470 employees of Payame Noor University in Kermanshah province. A sample of 212 people was chosen using Cochran formula. Data were collected through social capital questionnaire of Ownegh (2005), Akbari et al. (2013) and organizational performance of Baharestan et al. (2012). The validity (content, convergent, divergent) and reliability (factor load, composite Reliability coefficient, and Cronbach’s alpha coefficient) of questionnaires indicated that the measurement tools are of good reliability and validity. The results of the research by SMART-PLS software and using t test statistics and path coefficients (β) showed that social capital has strong, direct and significant impact on organizational learning and organizational performance. Also, social capital has strong, direct, indirect and significant impact on the organizational performance. On the other hand, organizational learning can play the mediating role in the relationship between social capitals on organizational performance. On the other hand, social capital can improve the positive effect that organizational learning has on the organizational performance as a moderating variable.

Youth participation in planning and design process in their living environments is an important issue that has significant impact on young participants, the community, spaces and places where they live. So, using their participation in the evaluation of youth friendly environmental quality indicators can lead to the creation of desirable urban spaces for them. After developing indicators on the basis of theoretical foundations of adolescent-friendly environments, this study attempts, to assess the importance of the indicators from 15 to 18-year-old adolescents’ view in making an ideal city, in Rasht Golsar district and to find that to what extent their living environments have been successful in meeting these measures. Research method, has been descriptive-analytic and theoretical foundations through library and teenagers’ view analysis with a combination approach was carried out through two questionnaires, focus group discussions and map anchored interviews. For this purpose, quantitative data analysis software method Excel and Spss and qualitative data analysis was conducted using content analysis. The results show that the studied indicators are very important for teens and most of these indicators has no place in their living environments.

In most countries, a major source of government revenue is funded through taxes. Tax share of total public revenues is different among countries and the rate depends on the level of development and economic structure. For this reason, the necessity to understanding of causes, aggravating factors, tax evasion, providing practical solutions and scientific recommendations will be inevitable. According to the current study by using a smooth transition regression (STR) and annual data from 1971-2015, we investigate the effects of direct financing through amendments of direct tax law on economic growth in Iran's conventional model of economic growth. The results of this study, along with the theoretical foundations and the prevailing belief of most economists, showed that the effect of different methods of financing through direct taxes on economic growth in Iran conditional on the state of the economy, in particular in accordance with the results of investment. It means that in the first regime, when the investment share of GDP is became less than 34/05 percent, financed by oil revenues has negative effects and financing through tax revenues had a positive effect on economic growth. But in the second regime, when the investment share of GDP is more than 28/01 percent, the financing of both oil and tax revenues had a positive effect on economic growth. Although in the second regime and by increasing the investment to keep pace with positive impact on the severity funded through tax revenues increased.
