One of the fastest growing areas is that of Internet gambling. The effect of such technologies should not be accepted uncritically, particularly as there may be areas of potential concern based on what is known about problem gambling offline. This article has three aims. First, it overviews some of the main social concerns about the rise of Internet gambling. Second, it looks at the limited research that has been carried out in this area. Third, it examines whether Internet gambling is doubly addictive, given research that suggests that the Internet can be addictive itself. It is concluded that technological developments in Internet gambling will increase the potential for problem gambling globally, but that many of the ideas and speculations outlined in this article need to be addressed further by large-scale empirical studies","tok_text":"the social impact of internet gambl \n technolog ha alway play a role in the develop of gambl practic and continu to provid new market opportun . one of the fastest grow area is that of internet gambl . the effect of such technolog should not be accept uncrit , particularli as there may be area of potenti concern base on what is known about problem gambl offlin . thi articl ha three aim . first , it overview some of the main social concern about the rise of internet gambl . second , it look at the limit research that ha been carri out in thi area . third , it examin whether internet gambl is doubli addict , given research that suggest that the internet can be addict itself . it is conclud that technolog develop in internet gambl will increas the potenti for problem gambl global , but that mani of the idea and specul outlin in thi articl need to be address further by large-scal empir studi","ordered_present_kp":[4,21,127,702,605],"keyphrases":["social impact","Internet gambling","market opportunities","addiction","technological developments","electronic cash","psychology"],"prmu":["P","P","P","P","P","U","U"]} {"id":"4","title":"Industry insiders loading up on cheap company stock","abstract":"A surge of telecom executives and directors purchasing their own companies, stock in the last two months points toward a renewed optimism in the beleaguered sector, say some observers, who view the rash of insider buying as a vote of confidence from management.
