  Business incubator is economic development tools that provide a set of business support resources and services for accelerate to growth and success of entrepreneurial companies. Today, advancement of the internet and moving the businesses toward cyberspace set up a virtual incubator can be very important, So in other countries are considered. In order of increasing competition firms in various industries and Existing dynamics in business environments, designing the business model can be introduction for starting a successful business. According to this, Attention to business model for virtual business incubators is important. This paper is designing the business model for virtual business incubator in Iran. This design is done by study of related literature, interviews with experts and benchmarking results of several successful virtual business incubators in the world. Currently, there are many models to identify the components of business model and their relationship but Osterwalder 9 element model is known as the most popular and most perfect version. In this paper, the ontology Osterwalder is used in order to designing the business model for virtual business incubator. This design can be efficient step to starting the operational of this national project and can be followed productivity, Enhancing organizational performance and profitability Manuscript profile

  2 - Investigation of Diameter and Height Growth of Willow and Alder in Road Fill-Slope Landslide Bioengineering Stabilization (Surdar-Watashan District Chamestan, Mazandaran)
  Seyed Ata ollah Hosseini
  The aim of this study was to evaluate the diameter and height growth of two native species of alder (Alnus glutinosa L. Gaertn.) and willow (Salix alba L.) planted in three treatments including natural mulches of straw, wood chips and bare soil without mulch (as control More

  The aim of this study was to evaluate the diameter and height growth of two native species of alder (Alnus glutinosa L. Gaertn.) and willow (Salix alba L.) planted in three treatments including natural mulches of straw, wood chips and bare soil without mulch (as control) treatments. The design of the experiments was in the form of split plots and in the form of completely random blocks located in Chamestan, Mazandaran. The results showed that the regression relationships between diameter and height in alder species were better than those of willow species completely randomly. The study area was in parcels 5 of series 3 district of Surdar -Watashan forestry plan in watershed 49 of forests in the north of the country. The regression coefficient for the independent variable of diameter and dependent variable of height was 0.65 in alder and 0.42 in willow. The results showed that the regression relationship between diameter and height in alder was better than willow species. According to the results of variance analysis, the blocks and treatments did not have a statistically significant difference. The wood chips treatment created the best situation, and after that, the straw treatment and finally the control treatment (bare soil) had a more unfavorable situation than the other treatments. Finally, alder had more favorable conditions for adaptation to the applied bioengineering conditions of the present study vs. willow. Manuscript profile

  This study sought to develop a social media-based business model for tourism industry. At the first stage, the main elements of the model were extracted from the related literature review and the Osterwalder and Pigneur’s business model framework. At the second stage, to evaluate and prioritize the identified elements, a questionnaire was developed and administered on 119 experts who were selected through snowball sampling. The collected data were then analyzed, using Smart PLS software and the elements were imbedded in the model in order of their importance. Applying multiple case study method, the business model of seven tourism companies who managed to successfully employ the potentials of social media to their benefit were analyzed in the final stage to validate the business model proposed by this study. The findings indicated that active presence in social media would affect the customer-related elements more than those of the supplier-related ones. In other words, the elements related to the relationship with customers, cost structure, value proposition, and distribution channels would be affected more than the elements related to revenue streams, key resources, key activities, and key partnerships.
