We propose that people treat prejudice as more legitimate when it seems rationalistic-that is, linked to a group's pursuit of collective interests. Groups that appear to be coherent and unified wholes (entitative groups) are most likely to have such interests. We thus predicted that belonging to an entitative group licenses people to express prejudice against outgroups. Support for this idea came from 3 correlational studies and 5 experiments examining racial, national, and religious prejudice. The first 4 studies found that prejudice and discrimination seemed more socially acceptable to third parties when committed by members of highly entitative groups, because people could more easily explain entitative groups' biases as a defense of collective interests. Moreover, ingroup entitativity only lent legitimacy to outgroup prejudice when an interests-based explanation was plausible-namely, when the outgroup could possibly threaten the ingroup's interests. The last 4 studies found that people were more willing to express private prejudices when they perceived themselves as belonging to an entitative group. Participants' perceptions of their own race's entitativity were associated with a greater tendency to give explicit voice to their implicit prejudice against other races. Furthermore, experimentally raising participants' perceptions of ingroup entitativity increased explicit expressions of outgroup prejudice, particularly among people most likely to privately harbor such prejudices (i.e., highly identified group members). Together, these findings demonstrate that entitativity can lend a veneer of legitimacy to prejudice and disinhibit its expression. We discuss implications for intergroup relations and shifting national demographics. © 2015 American Psychological Association. Source

This paper introduces a simple greedy algorithm for searching for high likelihood pedigrees using micro-satellite (STR) genotype information on a complete sample of related individuals. The core idea behind the algorithm is not new, but it is believed that putting it into a greedy search setting, and specifically the application to pedigree learning, is novel. The algorithm does not require age or sex information, but this information can be incorporated if desired. The algorithm is applied to human and non-human genetic data and in a simulation study. © 2012 Elsevier Inc. Source

Most of society's innovation systems - academic science, the patent system, open source, etc. - are "open" in the sense that they are designed to facilitate knowledge disclosure among innovators. An essential difference across innovation systems is whether disclosure is of intermediate progress and solutions or of completed innovations. We theorize and present experimental evidence linking intermediate versus final disclosure to an 'incentives-versus-reuse' tradeoff and to a transformation of the innovation search process. We find intermediate disclosure has the advantage of efficiently steering development towards improving existing solution approaches, but also has the effect of limiting experimentation and narrowing technological search. We discuss the comparative advantages of intermediate versus final disclosure policies in fostering innovation. © 2014 Elsevier B.V. All rights reserved. Source

One way to understand the growing impact of disasters is as the output of a positive feedback, or reinforcing, loop. This paper hypothesizes that population vulnerability of a country transforms exogenous hazards to disaster impact for that country, which negatively impacts its economy as measured by per capita income and its growth. This impact in turn increases the vulnerability of the country's population thus creating a reinforcing loop. Therefore, like the output of any positive feedback loop, disaster impact would grow exponentially. Having analysed data over 50 years (1963-2012) and 179 countries, we find the results to be consistent with this conceptual model. We also find that disaster impact worldwide has indeed grown exponentially over this period even after normalizing for the growing global population and global income. These findings indicate the existence of a feedback loop that requires strategic rethinking about disaster management and development jointly to break this vicious cycle. © 2016 Elsevier B.V. Source

Housing Studies | Year: 2010

The 1990s saw a considerable fall in young adult homeownership rates in Britain. There is a concern that the future might hold further falls as a result of reforms to financing higher education. Using estimates from a housing tenure choice model, this paper conducts micro-simulation analyses to assess how this change could affect young adult homeownership transitions. The simulations reveal that increased student debt levels and the new repayment profile and their interaction with lender-imposed borrowing restrictions delay a first-time homeownership transition. The extent of the delay primarily depends upon the expected earnings profile, but lender criteria and general rises/falls in real house prices are also important. The analysis suggests that there will be much greater variation in the timing of house purchase between different groups of future graduates, brought about by increased graduate earnings heterogeneity, homeownership affordability schemes targeted toward specific types of households, and parental financial assistance. © 2010 Taylor & Francis.
