Organizations are increasingly pursuing crowdsourcing initiatives to gain an understanding of community issues. A critical success factor for community crowdsourcing is to attract online volunteer crowdsourcing users and engage their interest besides extrinsic motivators like monetary rewards. Our study examines determinants of participant engagement in online crowdsourcing communities, specifi...

Objective: Today people are aware of the important role of agriculture as a vital source in their life. Development in agriculture and making healthy food for human, needs trained man. Vocational schools and agricultural training centers provided the first stage for arriving at this purpose. One of the reasons for the weak influence of agricultural training centers in creating occupational oppo...

Interest is increasingly being recognized as an effective motivator for learning, however neither the constructivist learning environment design literature nor the motivation research literature directly address the challenges of designing interest-driven learning activities. In this paper, we present a design framework for the creation of learning activities that draw on interest as their prim...

Complex surface structures have stimulated a great deal of interests due to many potential applications in surface devices. However, in the fabrication of complex surface micro-/nanostructures, there are always great challenges in precise design, or good controllability, or low cost, or high throughput. Here, we present a route for the accurate design and highly controllable fabrication of surf...

A spiring scholars rightly recognize publication of their first peer-reviewed paper as a critical career milestone. It signals active engagement with the discourse in a field and contribution to the body of knowledge. As editors, we celebrate along with those who receive a decision letter beginning with “Congratulations!”, even as we also applaud the efforts of all students advancing into the p...

Finding point correspondences between two views is generally based on the matching of local photometric descriptors. A subsequent geometric constraint ensures that the set of matching points is consistent with a realistic camera motion. Starting from a paper by Moisan and Stival, we propose an a contrario model for matching interest points based on descriptor similarity and geometric constraint...

landslides are among important mass movements of a great interest for earth scientists. this is due to their importance in land use and decision-making in rural and urban areas. survey of old landslides to determine their behavior has important bearing on the study of new ones. seimareh grand landslide is one of the oldest and the most attractive phenomenon that has been the subject of concern ...
