Crowd Access Path Optimization: Diversity Matters
Quality assurance is one the most important challenges in crowdsourcing. Assigning tasks to several workers to increase quality through redundant answers can be expensive if asking homogeneous sources. This limitation has been overlooked by current crowdsourcing platforms resulting therefore in costly solutions. In order to achieve desirable cost-quality tradeoffs it is essential to apply effic...
متن کاملInclusive Design in IS: Why Diversity Matters
After decades of research and ambitious political programs, we still observe imbalances in the treatment of people on the basis of gender, age, race, ethnicity, sexual orientation, religion, disability, and social background. Such an issue raises questions about the degree to which information systems can help to overcome such imbalance; for instance, if design principles can be formalized to r...
متن کاملCryptic matters: overlooked species generate most butterfly beta-diversity
to reproductively interfere between them (Pigot and Tobias 2013). Results for a series of cryptic butterfly species revealed only restricted contact zones on mainland and chequered distributions over narrow (3–10 km) sea straits (Dincă et al. 2011, Dapporto et al. 2012, Sañudo-Restrepo et al. 2013). If chequered distributions are overrepresented among cryptic species, they could encompass a dis...
متن کاملmRNA display: diversity matters during in vitro selection.
D Wilson, Anthony Keefe, and Jack Szostak have made a wonderful contribution to the changing world of peptide and protein in vitro evolution and selection. In a previous issue of PNAS (1), they demonstrated that the expected (and observed) weak affinities of peptides (from, for example, bead or phage display) can be enhanced by using ‘‘mRNA display.’’ The present work is a large step forward. T...
متن کاملSpace Matters: Estimating Species Diversity in the Fossil Record
Estimates for the number of living species on earth range from 3.5 million to over 30 million but only 1.9 million species have been classified and described. Estimating historical biodiversity from the fossil record is an even more daunting task. One tool ecologists but not paleontologists have traditionally relied on to identify patterns of existing biological diversity is a long-established ...
