Panacea or Band-Aid? First-/Last-Mile Connection in Public Transit Systems
First-/last-mile (FMLM) services have become an increasingly popular strategy intended to improve transit travel in the United States. However, empirical results about their benefits remain mixed. In this Viewpoint we critically examine the underlying mechanisms that steer decision making toward FMLM services and highlight the reality that in many community contexts, FMLM services do not effectively cater to rider needs. We argue that FMLM servic…

Woce Radiocarbon IV
The World Ocean Circulation Experiment, carried out between 1990 and 1997, provided the most comprehensive oceanic survey of radiocarbon to date. Approximately 10,000 samples were collected in the Pacific Ocean by U.S. investigators for both conventional large volume p counting and small volume accelerator mass spectrometry analysis techniques. Results from six cruises are presented. The data quality is as good or better than previous large-scale…
Target Preparation for Continuous Flow Accelerator Mass Spectrometry
For very small samples, it is difficult to prepare graphitic targets that will yield a useful and steady sputtered ion beam. Working with materials separated by preparative capillary gas chromatography, we have succeeded with amounts as small as 20 μg C. This seems to be a practical limit, as it involves 1) multiple chromatographic runs with trapping of effluent fractions, 2) recovery and combustion of the fractions, 3) graphitization and 4) comp…
Microscale AMS 14 C Measurement at Nosams
Techniques for making precise and accurate radiocarbon accelerator mass spectrometry (AMS) measurements on samples containing less than a few hundred micrograms of carbon are being developed at the NOSAMS facility. A detailed examination of all aspects of the sample preparation and data analysis process shows encouraging results. Small quantities of CO 2 are reduced to graphite over cobalt catalyst at an optimal temperature of 605°. Measured 14 C…
C AMS Measurements of <100 μG Samples with a High-Current System
The NOSAMS facility at Woods Hole Oceanographic Institution has started to develop and apply techniques for measuring very small samples on a standard Tandetron accelerator mass spectrometry (AMS) system with high-current hemispherical Cs sputter ion sources. Over the past year, results on samples ranging from 7 to 160 μg C showed both the feasibility of such analyses and the present limitations on reducing the size of solid carbon samples. One o…
Broadsided by broad traits
This paper is a conceptual and methodological critique of arguments advanced by Ones and Viswesvaran (1996, this issue) favoring ‘broad’ over ‘narrow’ personality traits for personnel selection and theoretical explanation. We agree with Ones and Viswesvaran that predictors should match criteria in terms of specificity. We depart from them, however, in our view of how traits should be chosen to obtain the best possible prediction and explanation o…

Woce AMS Radiocarbon I
AMS radiocarbon results from the World Ocean Circulation Experiment in the Pacific Ocean show dramatic changes in the inventory and distribution of bomb-produced 14 C since the time of the GEOSECS survey (8/73–6/74). Near-surface Δ 14 C values for the eastern portion of both the northern and southern subtropical gyres decreased by 25–50‰, with the change being greater in the north. Equatorial near-surface values have increased by ca. 25‰. Changes…

Predicting Involvement with Illicit Drugs Part I
This report describes some of the methodological issues raised in a feasibility study to develop a psychological test to predict illicit drug use. A small set of questions was found with different responses as a function of prior drug use. The ability of these questions to discriminate groups on the basis of prior drug use was maintained in a cross-validation study with different subjects. The extent to which these attitudinal correlates of drug …
The "Cosmographia" of Bernardus Silvestris
Several studies on the often turbulent relationship between the Christians and the Jews. The first, by Professor Hyam Maccoby, is a historical-theological overview of Christian anti-Judaism and anti-Semitism. The second study, by the editor, provides a critical historical-political overview of the We Remember document. Three theologians also respond to the Vatican document: Reverend John F. Morley, a Catholic; Professor Franklin H. Littell, a Pro…
