The traditional internet was designed over 40 years ago and has certain design flaws. End-users need to trust hidden middlemen like domain name servers and certificate authorities and trust remote data stores with their personal data. Blockstack is a new internet for decentralized applications that removes the need for trusted intermediaries and enables users to own their application data direc...

Crowdturfing has recently been identified as a sinister counterpart to the enormous positive opportunities of crowdsourcing. Crowdturfers leverage human-powered crowdsourcing platforms to spread malicious URLs in social media, form “astroturf” campaigns, and manipulate search engines, ultimately degrading the quality of online information and threatening the usefulness of these systems. In this...

A recent phenomenon in Internet marketing is the evolution of “virtual” organizations that provide free e-mail services or promotional rebates or even cash to “qualified” online consumers who are willing to interact with them. In order to qualify for such “goodies” the consumers provide these organizations information on their demographics, likes and dislikes, shopping/product preferences, etc....

In today’s Web, such services are generally lacking with the result that individuals are forced to manually discover, collate and analyse information to meet their needs. This paper begins by presenting the design and implementation o...

The present study focused on the women’s participation in Danish International Development Assistance (DANIDA) assisted small scale aquaculture projects in three coastal Districts of Bangladesh. The findings reveal that in most projects wom...

We analyze the behavior of a competitive n-tier supply chain system, where agents bargain with each other locally. We study the influence of transaction costs on the convergence of the system to a stationary outcome. In particular, we consider a dynamic bargaining game among a finite set of agents and its replications, and use a limit stationary equilibrium to examine the system’s behavior as t...

Although the Internet has enabled some new forms of sales practices to emerge, the majority of independent e-tailers merely act as slightly different types of electronic middlemen who sell largely undifferentiated products by performing virtually the same functions as what conventional retailers and wholesalers have been. Regardless of the type of intermediation, however, one of the critical pr...
