Learning When to Quit: An Empirical Model Of Experimentation in Standards Development
No full textUsing data from the Internet Engineering Task Force, a voluntary organization that develops protocols for managing Internet infrastructure, we estimate a dynamic discrete choice model
of the decision to continue or abandon a line of research. The
model’s key parameters measure the speed at which authors learn
whether their project will become a technology standard. We use
the model to simulate two innovation policies: an R&D subsidy
and a publication-prize. While subsidies have a larger impact on
research output, the optimal policy depends on the level of R&D

Pupil slicer design for the NASA-NSF extreme precision Doppler spectrograph concept WISDOM
No full textThe WIYN Spectrograph for Doppler Monitoring (WISDOM) was a concept responding to NASA's solicitation for an extreme precision radial velocity instrument for the 3.5 meter WIYN telescope on Kitt Peak in Arizona. In order to meet the spectral resolution requirement of R = 110,000 while maintaining good throughput and a manageable beam diameter, the front end design of the instrument employed a pupil slicing technique wherein a collimated beam is sliced and fed to six separate fibers. This paper presents the optical and mechanical design of the pupil slicer subassembly, a unique method of dealing with thermally induced defocus error, and the methods and results of aligning a prototype
Increasing chloride concentrations in Lake Simcoe and its tributaries
No full textChloride concentrations in Lake Simcoe have increased significantly (P &lt; 0.001) over a 36-year period during which the human population in the watershed has grown. Lake concentrations are now between 36 and 40 mg/L, having increased more than three-fold at the lake's outflow since 1971. Concentrations increased significantly in eight tributaries of the lake from 1993 to 2007 (P &lt; 0.05), and were highest in those rivers draining the greatest percentage of urban land and roads, and in a river close to a major highway. The cumulative chloride load estimated at the mouths of seven rivers flowing into Lake Simcoe ranged from 11,563 to 32,107 tonnes/year from 1998 to 2007, and increased significantly over this period (P &lt; 0.05). The fluxes or unit area loads of chloride, averaged from 2004 to 2007 for each of 10 tributaries, were positively correlated with the proportion of urban land and roads drained (P = 0.005, r = 0.80). Although Lake Simcoe is a large lake and only 12% of its watershed drains urban land and roads, evidence of road salt application can already be seen. This indicates that inputs must be reduced to preclude future ecological impacts on the lake.</jats:p

Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

Annual water balances and phosphorus loading for Lake Simcoe (1990-1998)
No full textOne of the primary objectives of Phase II of the Lake Simcoe Environmental Management Strategy was to estimate the total phosphorus loading upon the Lake Simcoe catchment. This report presents methods and results relating to that objective, based on the hydrologic water year of June 1st to May 31st of the subsequent year 1990 - 1998. A three-stage analysis of annual water balances was performed on the hydrological data collected throughout the study period . An annual summary of total phosphorus loads (kg yr-1) to Lake Simcoe is presented in which five point source categories are proportionally described. The atmospheric and tributary sources constitute the greatest overall contribution. Atmospheric contribution ranged from 23% (1996-97) to 56% (1993-1994) while tributaries accounted for 17% (1994-95) to 48% (1992-93) of total phosphorus loads. Urban non-point sources were the third largest source, ranging from 9% (1990-91) to 22% (1994-95 & 1997-98). Urban point sources (sewage treatment plants) and vegetable polders contributed the least with very similar proportions of total phosphorus load to Lake Simcoe. The urban point source ranged from 3% (1990-91, & 1992-93) to 8% (1994-95) and the vegetable polders were from 2% (1994-95) to 8% (1995-96 & 1996-97) of total phosphorus loads
