We study the impact of social influence on the performance of ads on social networks. Using data for several ads on Facebook for two different firms, we measure the impact of past connections on the click rate and endorsement rate of ads. We find that increase in the connections does not lead to an increase in the click performance and may even decrease the click performance. We also find that ...

Many researchers in the field of international business have argued that cultural proximity can positively influence bilateral trade. These researchers have attempted to develop proxy measures for cultural proximity, such as language, ethnicity, religion, and trade of cultural goods. However, the conventional measures failed to capture the time-variant characteristics of cultural affinity or di...

With the development of information resources, there are more and more CD-ROM resources. The traditional disc management, storage and search methods can not meet the current requirements of the fast-paced CD-ROM management infomationization and standardization. Based on the demand, we studied a distributed intelligence disc management system with random access, fuzzy search and automatic pop-up...

This paper focuses on access control approaches usable for information sharing through large screens where several individuals are present at the same time. Access control in this setting is quite different from traditional systems where a user logs on to the system. The paper outlines a number of possible approaches to access control, and evaluates them based on criteria derived from risk anal...

In this paper a humming method for music information retrieval is presented. The system uses a database with real songs and does not need another type of symbolic representation of them. The system employs an original fingerprint based on chroma vectors to characterize the humming and the references songs. With this fingerprint, it is possible to get the hummed songs without needed of transcrip...

Estimating the size of OO software is the main issue today in project planning and development. Accurate estimation of size may lead to precise prediction of effort during the process of system development. Predictive Object Point POPs are a metric designed specifically for estimating the size of object oriented software. But there is no direct relation between POP and Software size. In this pa...

This paper describes a new planner, HiPOP (Hierarchical Partial-Order Planner), which is domain-configurable and uses POP techniques to create hierarchical time-flexible plans. HiPOP takes as inputs a description of a domain, a problem, and some optional userdefined search-control knowledge. This additional knowledge takes the form of a set of abstract actions with optional methods to achieve t...

Interruption-based advertising has gained prominence in the online channel. Yet, little attention has been paid to deriving design principles and conceptualizations for online interruption-based advertising. This paper examines three novel design factors related to this phenomenon, namely, exposure timing, advertising intent and brand image. Exposure timing pertains to the time by which the ad ...

We study the chemical evolution of population I and population II secondaries in cata-clysmic variables (CVs) assuming that during nova explosions a part of the high metal-licity nova ejecta is intercepted by the secondary and mixed into its convective envelope. We derive analytic expressions for the chemical composition of the secondary's envelope as a function of the chemical composition of t...
