A sustained outbreak of pine false webworm, Acantholyda erythrocephala (L.) (Hymenoptera: Pamphiliidae), in northern New York is unprecedented in its extent and duration. White pine, Pinus strobus L., is the preferred host in this region. What began as a 30-ha infestation of this introduced sawfly in 1981 affected 5440 ha of white pine distributed throughout 231 000 ha in St. Lawrence and Franklin counties by 1995. Occurrence of A. erythrocephala in the United States has been documented in eight northeastern and one north-central state (Connecticutt, Massachusetts, Maine, New Hampshire, New Jersey, New York, Pennsylvania, Vermont, and Wisconsin) and three Canadian provinces (Alberta, Newfoundland, and Ontario). Possible explanations for the occurrence and tenure of the current outbreak in New York are discussed.

AbstractThe life history of pine false webworm, Acantholyda erythrocephala (L.), in three pine (Pinaceae) plantations in northern New York is similar to that reported for this species on red pine, Pinus resinosa Aiton, in Ontario. Adult emergence extended from early May to early June. The sex ratio of emerging adults favored males by as much as 2.7:1. Oviposition occurred from mid-May to early June. Significantly more eggs per fascicle were deposited on the distal third of branches and in the lower third of the crown. Larval feeding took place throughout June. The proportion of prepupae remaining in the soil for more than 1 year varied from 9% to 66% between two sites. There was no evidence of egg parasitism, and egg survival exceeded 95% in each of 2 years. A new species of nematode (Steinernema sp.) (Nematoda: Steinernematidae) was recovered from pronymphs. Homaspis interruptus (Provancher) (Hymenoptera: Ichneumonidae) parasitized larvae and emerged from 8.5% and 2.8% of the pronymphs in two populations.

White pine blister rust, Cronartium ribicola J. C. Fischer, requires a pine (Pinus L.) and a Ribes L. as obligate alternate hosts. The center of diversity for this rust is east of the Ural Mountains, where the organism evolved with P. cembra L and R. nigrum var. sibericum L over several million years. Susceptible Pinus strobus L from North America was imported into England in 1710 and was transplanted throughout eastern Europe. In 1865, rust was first reported on these introduced pines in Eastonia. In the late 1800s, the white pine nursery industry continued to develop in Europe, but was declining in the United States. American foresters began importing white pines from Europe. Rust was found on cultivated currants in New York in 1906 and U.S. inspectors began examining for the disease. In 1910, infected white pines were imported from France into Vancouver, British Columbia; in 1911, infected pines were found in New Hampshire, Vermont, Massachusetts, Connecticut, Pennsylvania, Indiana, Ohio, Ontario, and Quebec. Additional rust-infected imported pines were found in nurseries in Wisconsin in 1913, and Minnesota in 1914. Rust spread to native pines in New York by 1915 and to Idaho by 1927. A summary of the blister rust control program, the recent spread of the disease, and the present state regulations will be presented.

Abstract This article presents a history of the origins and development of the AMA Guides to the Evaluation of Permanent Impairment (AMA Guides), from the publication of an article titled “A Guide to the Evaluation of Permanent Impairment of the Extremities and Back” (1958) until a compendium of thirteen guides was published in book form in 1971. The most recent, sixth edition, appeared in 2008. Over time, the AMA Guides has been widely used by US states for workers’ compensation and also by the Federal Employees Compensation Act, the Longshore and Harbor Workers’ Compensation Act, as well as by Canadian provinces and other jurisdictions around the world. In the United States, almost twenty states have developed some form of their own impairment rating system, but some have a narrow range and scope and advise evaluators to consult the AMA Guides for a final determination of permanent disability. An evaluator's impairment evaluation report should clearly document the rater's review of prior medical and treatment records, clinical evaluation, analysis of the findings, and a discussion of how the final impairment rating was calculated. The resulting report is the rating physician's expert testimony to help adjudicate the claim. A table shows the edition of the AMA Guides used in each state and the enabling statute/code, with comments.

Louis Menand’s The Metaphysical Club, daunting in its choice of subject matter, closely aligns itself with the ancient sense of the word ‘history’ as a fluid, almost epic narrative. The Metaphysical Club of the title was a conversation group that met in Cambridge for a few months in 1872. Its membership roster listed some of the greatest intellectuals of the day: Charles Peirce, William James, Oliver Wendell Holmes, Chauncey Wright, amongst others. There is no record of the Club’s discussions or debates—in fact, the only direct reference to the Club is made by Peirce in a letter written thirty-five years later. Menand utilizes the Club as a jumping-off point for a sweeping analysis of the beliefs of the day. The subtitle of the book belies its true mission: ‘a story of ideas in America.’ Menand discusses the intellectual and social conditions that helped shape these men by the time they were members of the Club. He then shows the philosophical, political, and cultural impact that these men went on to have. In doing so, Menand traces a history of ideas in the United States from immediately prior to the Civil War to the beginning of the Cold War.

The aim of the Ukrainian Bureau in Washington was propaganda of Ukrainian question among US government and American publicity in general. Functioning of the Bureau is not represented non in Ukrainian neither in foreign historiographies, so that’s why the main goal of presented paper is to investigate its activity. The research is based on personal papers of Ukrainian diaspora representatives (O. Granovskyi, E. Skotzko, E. Onatskyi) and articles from American and Ukrainian newspapers. The second mass immigration of Ukrainians to the US (1914‒1930s) has often been called the «military» immigration and what it lacked in numbers, it made up in quality. Most immigrants were educated, some with college degrees. The founder of the Ukrainian Bureau Eugene Skotzko was born near Western Ukrainian town of Zoloczhiv and immigrated to the United States in late 1920s after graduating from Lviv Polytechnic University. In New York he began to collaborate with OUN member O. Senyk-Hrabivskyi who gave E. Skotzko task to create informational bureau for propaganda of Ukrainian case. On March 23 1939 the Bureau was founded in Washington D. C. E. Skotzko was an editor of its Informational Bulletins. The Bureau biggest problem was lack of financial support. It was the main reason why it stopped functioning in May 1940. During 14 months of functioning Ukrainian Bureau in Washington posted dozens of informational bulletins and send it to hundreds of addressees; E. Skotzko, as a director, personally wrote to American governmental institutions and foreign diplomats informing about Ukrainian problem in Europe. Ukrainian Bureau activity is an inspiring example for those who care for informational policy of modern Ukraine.Keywords: Ukrainian small encyclopedia, Yevhen Onatsky, journalism, worldview, Ukrainian state.
