Nominalization and Alternations in Biomedical Language

Background: This paper presents data on alternations in the argument structure of common domain-specific verbs and their associated verbal nominalizations in the PennBioIE corpus. Alternation is the term in theoretical linguistics for variations in the surface syntactic form of verbs, e.g. the different forms of stimulate in FSH stimulates follicular development and follicular development is stimulated by FSH. The data is used to assess the implications of alternations for biomedical text mining systems and to test the fit of the sublanguage model to biomedical texts. Methodology/Principal Findings: We examined 1,872 tokens of the ten most common domain-specific verbs or their zerorelated nouns in the PennBioIE corpus and labelled them for the presence or absence of three alternations. We then annotated the arguments of 746 tokens of the nominalizations related to these verbs and counted alternations related to the presence or absence of arguments and to the syntactic position of non-absent arguments. We found that alternations are quite common both for verbs and for nominalizations. We also found a previously undescribed alternation involving an adjectival present participle. Conclusions/Significance: We found that even in this semantically restricted domain, alternations are quite common, and alternations involving nominalizations are exceptionally diverse. Nonetheless, the sublanguage model applies to biomedica

Beliefs in Conspiracy Theories Among African Americans: A Comparison of Elites and Masses

Several studies have reported a widespread belief in conspiracy theories among African Americans. Such theories have been shown to have possible deleterious effects, especially when they deal with HIV/AIDS. It has been conjectured that African-American elites could play a role in dispelling these beliefs, unless, of course, they believe in these theories themselves. To examine this possibility the present study examines the conspiratorial beliefs of African-American locally elected officials in Louisiana and compares them with a previous study of African-American churchgoers in the same state.

Executions, Deterrence and Homicide: A Tale of Two Cities

We compare homicide rates in two quite similar cities with vastly different execution risks. Singapore had an execution rate close to 1 per million per year until an explosive twentyfold increase in 1994-95 and 1996-97 to a level that we show was probably the highest in the world. Then over the next 11 years, Singapore executions dropped by about 95%. Hong Kong, by contrast,has no executions all during the last generation and abolished capital punishment in 1993. Homicide levels and trends are remarkably similar in these two cities over the 35 years after 1973, with neither the surge in Singapore executions nor the more recent steep drop producing any differential impact. By comparing two closely matched places with huge contrasts in actual execution but no differences in homicide trends, we have generated a unique test of the exuberant claims of deterrence that have been produced over the past decade in the U.S
