Most commercial sweetpotato acreage in the United States is grown from plants that have been produced from bedded roots. Development of new methods or new combinations of known methods to increase plant production helps to maximize the number of usable plants produced in a minimum amount of time and also reduces propagation costs while aiding early transplanting. Plant production is influenced greatly by genotype, and many efforts have been directed at improving plant production from sparse plant producing cultivars. Modifications of wounding or cutting treatments, exposure to chemical sprout inducers, presprouting by heat treatments and combinations of these treatments have enhanced plant production from large and small roots of sparse and profuse plant producing cultivars.

AbstractGreat efforts are devoted to end the HIV epidemic as it continues to have profound public health consequences in the United States and throughout the world, and new interventions and strategies are continuously needed. The use of HIV sequence data to infer transmission networks holds much promise to direct public heath interventions where they are most needed. As these new methods are being implemented, evaluating their benefits is essential. In this paper, we recognize challenges associated with such evaluation, and make the case that overcoming these challenges is key to the use of HIV sequence data in routine public health actions to disrupt HIV transmission networks.

The Liriomyza (Diptera: Agromyzidae) of Canada and Alaska is revised, with species keyed and illustrated, and new host and geographic records provided. Eighty one species are recognized, including 24 new to science: L. agrios, L. albispina, L. anatolis, L. aphila, L. apilaca, L. aquapolis, L. arenarium, L. atrassimilis, L. bicolumbis, L. charada, L. cracentis, L. elevaster, L. emaciata, L. fumeola, L. gibsoni, L. griffithsi, L. hilairensis, L. limopsis, L. mesocanadensis, L. pilicornis, L. pistilla, L. rigaudensis, L. taraxanox, L. taraxanuda, L. tryssos. Ten species known from the United States are recorded as new to Canada: L. artemisiae Spencer, L. assimilis (Malloch), L. baccharidis Spencer, L. helianthi Spencer, L. merga Lonsdale, L. minor Spencer, L. sabaziae Spencer, L. temperata Spencer, L. violivora (Spencer) and L. virgo (Zetterstedt). Palaearctic species new to North America include L. wachtli Hendel and L. flaveola (Fallén); while the latter species has been recorded in North America before, all previous records represent misidentifications. Hosts are recorded for the first time for L. balcanicoides Sehgal, L. minor Spencer, L. orilliensis Spencer and L. socialis Spencer. Galiomyza Spencer syn. nov. is included as a junior synonym of Liriomyza Mik, resulting in six new combinations.

New Methods

Biological warfare, “Public Health in Reverse,” calls for new methods of fighting disease, because when disease is willfully spread, it can take on new aspects. By understanding why an enemy may choose to use BW instead of some other weapon, we may be able to forecast its use and prepare to repel it. Various BW agents, means of distribution, and required properties are discussed. Although counteracting forces now exist in the health services of the United States, we must fashion and learn to use special defensive weapons. The author outlines four essential elements in a program of defense against BW.

Small Band

During the period of about ten years which included that of Mallet's death—say, five years before and five after—the study of earthquakes made rapid progress. Among the more prominent contributors were M. S. de Rossi and G. Mercalli in Italy, F. A. Forel and A. Heim in Switzerland, E. Suess in Austria, J. F. J. Schmidt in Greece, T. Oldham in India, and C. G. Rockwood and C. E. Dutton in the United States. Their work, however, was mainly carried out on the old lines. For the introduction of new methods of study and of a new spirit infused into seismology, we are indebted to the small band of early British teachers in Japan, to J. A. Ewing, T. Gray, and, above all, to J. Milne. In the new epoch, now opening, when seismology demanded the whole energy of its supporters as well as their active co-operation, it is not, I think, too much to claim that Milne lifted the science to an altogether different and higher plane.

Bacterial angular leafspot disease (BALD) of strawberry (Fragaria sp. and F. ×ananassa Duchesne cultivars) has become increasingly destructive to strawberry fruit and plant production in Canada and the United States, as well as in other countries. The disease, caused by Xanthomonas fragariae Kennedy and King, was first documented in Minnesota in 1960, and has become of worldwide concern because of the economic impact of BALD in strawberry fruit and nursery-plant production and the lack of adequate disease control strategies. We tested 81 Fragaria genotypes, including representatives of F. ×ananassa, F. chiloensis (L.) Duchesne, F. virginiana Duchesne, and F. vesca L., for resistance to two pathogenic strains of X. fragariae. Two genotypes, a native F. virginiana from Minnesota and an F. virginiana × F. ×ananassa hybrid, were found to resist infection by both bacterial strains and may be potential sources of resistance to other strains of X. fragariae.

Living Newspapers

This article examines the migration of a Soviet agitational theatrical form from Russia to the United States in the 1920s and 1930s. The Soviet living newspaper, or zhivaia gazeta, began during the Russian Civil War as a method to act out a pro-Soviet version of the news for mainly illiterate Red Army soldiers. During the 1920s, it evolved into an experimental form of agitprop theater that attracted the interest of foreigners, who hoped to develop new methods of political theater in their own countries. In the United States, the living newspaper format was first adopted by American communist circles. Eventually, the depression-era arts program, the Federal Theatre Project (FTP), incorporated an expanded and altered version as part of its many offerings. Living newspapers eventually became one of the FTP’s most celebrated and criticized performance genres. The political content of American living newspapers was a major factor in the government’s elimination of the FTP in 1939.

The Comparative Study

This chapter summarizes new approaches to the study of traditional dialects, in particular in Britain and the United States, and discusses how new methods, new results, and new topics of investigation may inform and enrich the study of World Englishes, too. Of particular importance may be the acknowledgement of widespread variability in the ‘homeland’ that is increasingly also historically attested and sociolinguistically described, the study of morphosyntactic variation as an area of language that seems to remain quite stable under settlement conditions, and the comparative study of present-day variability that indicates the breadth (and limits) of variability. In return, results from the comparative study of World Englishes also have the potential to enrich modern dialectology and sociolinguistics.

The Conference on the Limitation of Armament at Washington adopted at its sixth plenary session on the 4th February, 1922, a resolution for the appointment of a Commission representing the United States of America, the British Empire, France, Italy and Japan to consider the following questions:(a) Do existing rules of international law adequately cover new methods of attack or defence resulting from the introduction or development, since The Hague Conference of 1907, of new agencies of warfare?(b) If not so, what changes in the existing rules ought to be adopted in consequence thereof as a part of the law of nations?
