Due to the increasing concentration of Kermanshah dust phenomenon in recent years, The aim of this study was to measure the concentration of the sensitivity coefficients between dust phenomenon hospitalization and mortality rates for heart and respiratory. Materials and Methods: This was a descriptive study in which we studied the sensitivity coefficient of hospitalization and mortality rates for heart disease and respiratory to changes of dust concentration.. The study duration was during March-September 2010 and 2011. We collected the dust phenomenon data from Kermanshah Province Environmental Protection Department. The admissions and mortality of the cardiovascular and respiratory sufferers was collected from the Imam Ali, Imam Reza, and Imam Khomeini governmental hosiptals in Kermanshah. Results: 1% increase in air pollution caused by the dust phenomenon will result in increasing about 0.5 % of the respiratory patients, 1% cardiac patients, and about 0.3% of the heart disease mortality. The relationship between dust phenomenon and respiratory sufferers was statistically not significant. Conclusions: We found that respiratory and cardiovascular hospital admission has a high sensitivity to dust phenomenon. This sensitivity has increased from 2010 to 2011. This sensitivity was greater for males than females. At least, during March-September 2010, for every 100% increase in the concentration of dust phenomenon, cardiovascular mortality increased by 29%.

Research paper thumbnail of Inclusive urban entrepreneurial ecosystem policies: An application of the meta‐synthesis approach

Despite the nature of entrepreneurship to facilitate economic development, there are limited studies regarding the related concept of inclusive development. This issue is the motivating factor for this study to introduce the concept of inclusive urban entrepreneurial ecosystem (IUEE). IUEE provides a market‐ and resource‐based view of poverty alleviation and can be considered as a new pattern of inclusive business (IBs) growth. Hence, the aim of this study is to formulate policies for IUEE by conducting a qualitative meta‐synthesis of the theoretical literature. In this meta‐synthesis, we synthesized a total of 155 findings from 64 studies conducted to date. The results are grouped into 17 concepts and nine main policies as follows: IUEE modeling, considering the role of IBs, improving the ecosystem members' social interactions, supporting inclusive entrepreneurship intermediaries, sustained commitment to inclusive entrepreneurship, strengthening learning opportunities in the ecosystem, maintaining the ecosystem diversity and dynamics, improving the inclusive entrepreneurship facilities and managing the inputs and outputs of the ecosystem. The findings of this study can be used to develop IUEEs and achieve entrepreneurial cities.

The objective of the present descriptive analytical study was to determine and compare the cost/effectiveness ratios of two types of wastewater treatment systems operating in Kermanshah Province. For this purpose, data and information on the wastewater treatment plants under study were collected from both local water and sewage companies and treatment plant operators. The data were then subjected to statistical analysis using the SPSS software program. All the costs assoiated with the erection and operation of the treatment processes were analyzed and plant efficiencies were determined to work out the cost/effectiveness index for each plant as a basis for comparisons. Average values of overall efficiency determined from the mean values of total suspended solids, biochemical oxygen demand, and chemical oxygen demand removals in both activated sludge and natural systems were found to be 76.37±18.19% and 61.69±19.0%2, respectively. Also, the two systems were found to be significantly different with respect to their overall efficiency. Moreover, the cost/effectiveness ratios obtained for the two activated sludge and natural systems were 0.23 and 0.58, respectively. Based on the results obtained, it may be claimed that, despite their lower efficiency, natural treatment systems outperform activated sludge ones due to their higher cost/effectiveness ratio, which makes them superior to the activated sludge process. Natural treatment systems owe their superiority to their lower investment, operation, and maintenance costs.

One of its important dimensions is paying attention to social justice within the framework of regional equilibrium. The present article tries to investigate this important dimension for the tenth government in Iran. With the aim of analyzing regional equilibrium process and providing priorities for the development of the provinces can play an effective role in national policies to promote regional equality and decentralization. Using multi-dimensional decision making (MADM) and Topsis model, after the formation of a Regression and Matrix model with 21 indicators and 157 sub-indicators for the developmental level of the provinces, it was revealed that Tehran and South Khorasan provinces placed first and last respectively and using the cluster model Iranian provinces were categorized into five groups from which one province was ...

This study examines the factors affecting production efficiency by using province-level data for the period 2006-2015 by applying spatial Tobit model and translog production function approach. Results show that Chaharmahal and Bakhtiari and Khorasan Razavi Provinces, have the highest and lowest efficiency 0.63 and 0.09 respectively. Also, the results of spatial Tobit model estimation show that industrialization with a coefficient of 0.0018 has a positive and significant effect and increase of ratio of credits to production with a coefficient of 0.0013 has a negative and significant effect on the production efficiency of provinces. In addition, the spillover effects of industrialization and the ratio of credits are -0.0104 and 0.0042 respectively. Therefore basic development of industry and allocation of resource on the relative advantage is one ...
