1.  Trends in American Board of Psychiatry and Neurology specialties and neurologic subspecialties 
Neurology  2010;75(12):1110-1117.
Objective: To review the current status and recent trends in the American Board of Psychiatry and Neurology (ABPN) specialties and neurologic subspecialties and discuss the implications of those trends for subspecialty viability.
Methods: Data on numbers of residency and fellowship programs and graduates and ABPN certification candidates and diplomates were drawn from several sources, including ABPN records, Web sites of the Accreditation Council for Graduate Medical Education and the American Medical Association, and the annual medical education issues of the Journal of the American Medical Association.
Results: About four-fifths of neurology graduates pursue fellowship training. While most recent neurology and child neurology graduates attempt to become certified by the ABPN, many clinical neurophysiologists elect not to do so. There appears to have been little interest in establishing fellowships in neurodevelopmental disabilities. The pass rate for fellowship graduates is equivalent to that for the “grandfathers” in clinical neurophysiology. Lower percentages of clinical neurophysiologists than specialists participate in maintenance of certification, and maintenance of certification pass rates are high.
Conclusion: The initial enthusiastic interest in training and certification in some of the ABPN neurologic subspecialties appears to have slowed, and the long-term viability of those subspecialties will depend upon the answers to a number of complicated social, economic, and political questions in the new health care era.

2.  Factors Affecting the Infection of Alfalfa Seedlings by Ditylenchus dipsaci 
Journal of Nematology  1975;7(4):380-383.
Experiments were conducted to determine the effects of plant confinement, soil type, watering practices, stage of seed germination, inoculum level, and method of applying inoculum on stem nematode (Ditylenchus dipsaci) infection of alfalfa (Medicago sativa) seedlings grown in soil. Results indicated that (i) confining seedlings together with the nematodes in small vials offered no advantage over growing plants in large flats, (ii) a very fine sandy-loam soil was superior to a fine sand for stem-nematode penetration, (iii) nematodes penetrated seedlings more readily if the soil was not watered immediately after planting and inoculation, (iv) germinating seeds with a radicle length of 0.6-1.3 cm had the highest nematode penetration, and (v) highest penetration occurred when the nematodes were placed directly upon germinating seeds. The optimum inoculum level was 50 nematodes per seedling.

3.  Mass Culturing of Ditylenchus dipsaci to Yield Large Quantities of Inoculum 
Journal of Nematology  1974;6(3):126-129.
Methods are described for rearing large quantities of Ditylenchus dipsaci on alfalfa tissues. Nematodes and alfalfa seed were disinfected and nematodes were reared in quantities sufficient to provide a continuous supply of inoculum for our alfalfa-breeding program. Nematodes reproduced best in darkness at 20-25 C. Cultures reached maximum numbers in 3-6 wk.

4.  Acquisition and Distribution of Nematodes in Irrigation Waterways of the Columbia Basin in Eastern Washington 
Journal of Nematology  1970;2(4):362-367.
The primary source of plant parasitic nematodes in irrigation waterways in the Columbia Basin Project of eastern Washington is irrigation runoff returned into the irrigation system. This has contributed to the rapid spread of plant parasitic nematodes observed during eight years of study.

5.  Agriculturally-polluted Irrigation Water as a Source of Plant-Parasitic Nematode Infestation 
Journal of Nematology  1970;2(4):368-374.
Water from a major irrigation canal and water from a deep well was used to irrigate plants growing in methyl bromide fumigated screenhouse ground beds. Nematode populations in these beds were compared during three seasons of continuous cropping to alfalfa, bean, eggplant, mint, sugarbeet, or wheat. Beds irrigated with canal water became heavily infested with a variety of plant parasitic nematodes while those receiving well water did not.
