This thesis is an exploration on the growth and profitability models of Internet enterprises. Via literature review and interview with experts ,we try to answer the following questions: 1.What's the vision of Internet? 2.How Internet enterprises expand and grow? 3.How to earn profits? And how to generate the synergy by connecting them with each other? 4.Are there any ways to maintain continuous growth and profitability? From the general influence diagram of Heijden, we could believe that knowledge management is the basis of growth, value chain is the gravity center of development, and continuous innovation is the driver of growth. However, the main actions to make external growth are strategic alliance and M&A, and they are also the fastest ways to expand the scale of business. Furthermore, our research also finds that there are ten profit models with respect to dot com companies. They are (1)Customer Solutions Profit, (2)Value Chain Position Profit , (3)Time Profit , (4)Specialization Profit, (5)Brand Profit , (6)New Product Profit , (7)Switchboard Profit , (8)Blockbuster Profit, (9)Patronize Profit ,and (10)Returns Sharing Model¡C Every dot com company could select 2 or 3 models to manage her business and make profits. For network ecology being continuously changeable, every company could develop suitable profit models according to her management character. Finally, by analyzing that how SOFTBANK CO., a venture capital, expands her Netbatsu kingdom, we conclude that cooperation between dot com companies is the best way to survive and grow stronger.

Over the last few years, there has been a growing interest for social robots withhuman-like behavior and their application in healthcare and education. However,there are still plenty of issues that needs to be resolved. One of these challenges isto enable the social robots to fill its role effectively, by creating engagement. In this report the study, that was conducted at IBM Sweden, aims to understandhow IBM Watson can be utilized in the Pepper robot; to engage and supportchildren from the Ronald McDonald House in Uppsala. This is a place for childrenwith health problems and their families to live temporarily. Furthermore, supportivebehaviors are investigated since such behaviors are suggested to be important toincrease the engagement. An initial prototype that used Watson's natural languageprocessing and Pepper, was developed based on user requirements gatheredthrough interviews using a User Centered Design methodology. The prototype wasiteratively developed, and a final evaluation was conducted that examined both theperception of the robot as well as the engagement it created. The evaluation showed that the children wanted to interact with the robot again andhighlighted that they were highly engaged. They perceived the robot as a friend andthe supportive behaviors such as giving praise, responding quickly and maintainingeye contact were most important. The main support the children wanted were tohelp them feel less lonely and the conclusion of this study is that this is a suitablegoal for a robot system.
