At the 1977 meeting of the HFS a concept was presented for a Standard Ergonomics Reference Data System. The system would have two goals (1) the critical evaluation and integration of data from the existing published ergonomics literature, and (2) the development and application of standard measurement methods to collect key ergonomics data representative of the U.S. population not found in the published literature in a reliable form. This presentation will cover progress made in 1978 to assess user data needs and develop critical evaluation criteria, in light of significant overall program planning changes.

At the first International Meeting on Radio-Aids to Marine Navigation held in London in May 1946 some 105 delegates of twenty-three maritime nations met to discuss and witness demonstrations of some of the remarkable advances made in radio-navigation during the war and to consider the progress made in relation to their peacetime uses for marine transport.At the invitation of the U.S. government a second meeting was held a year later, in New York and New London, to show the progress made in America, to illustrate, with demonstrations, the U.S. policy and to pave the way to international standardisation. The U.K. delegation was led by Sir Robert Watson-Watt.

This article presents an exploration of the discourse-level phenomenon known as ‘backwards talk’ in Smith Island, a small, endangered dialect community in Maryland’s Chespaeake Bay, on the U.S. mid-Atlantic coast. The article examines how backwards talk, basically pervasive, highly creative irony, compares with irony more generally; how it patterns across generations and contexts; how important it is to island residents, who view backwards talk as the defining feature of their dialect; and why the feature has gained such importance in the face of dialect loss - and potential loss of community continuity as well. Because backwards talk is irony, it has important solidarity functions. As playful, nonliteral language, it serves as a symbol of the performed ‘islandness’ that islanders increasingly take up as they come into more and more contact with outsiders. Finally, as a means of offering critical evaluation of outsiders, backwards talk can be seen as a form of anti-language or counterlanguage, with a central function of resistance against outside forces.

Although transnational surrogacy has received much criticism owing to racial and class issues, the U.S. media portrays domestic surrogacy with overwhelming positive languages by employing specific narrative frameworks. Accompanying this shift, it is not so surprising that the number of gestational carrier cycles have skyrocketed from 727 to 3,423 over the last decade. (Note 1) In particular, increase in the number of gay and single men looking for surrogacy has yielded more controversies. This paper asks the following questions: How does the documentary Made in Boise present surrogacy in the context of a broader debate over feminist and LGBT’s positions? How are gay parents used in the altruism narrative framework to downplay exploitation of surrogacy? By providing insight into the intricate economic and power relationships between surrogate and a new emerging group of intended parents, my case study prompts broader questions such as: How to best document the most authentic narratives of the surrogates? How can feminist and LGBT scholars reconcile their viewpoints over surrogacy? These are pertinent questions concerning exploitation and coercion in the industry, thus influencing future feminists’ studies on reproductive technology and politics.

For those who are interested in the advancement of pediatric surgery, it has long been obvious that improvements should be made in anesthesia for infants and children. Much credit should go to Drs. Leigh and Beltom for their important efforts in this direction. The present volume is based on an extensive experience with anesthesia technics in young subjects and hence bears a mark of authority. The book is a good source of reference data for those who are called upon to work in this field.

Scholarship on musical settings of Walt Whitman’s When Lilacs Last in the Dooryard Bloom’d has only briefly looked into one of the most ambitious pieces composed on the poem in the earlier twentieth century: the Austrian woman composer Johanna Müller-Hermann’s orchestral cantata Lied der Erinnerung, premiered in Vienna in 1930. Through the piece has not remained in the repertoire, seen in light of its original context the cantata was a rich site for negotiating a complex terrain of ‘American’, ‘Austrian’, and ‘universal’ concepts. Through her structural decisions involving Whitman’s poem, her attempts to have the work reach American audiences, her use of borrowed melodies, and claims made in the work’s program notes, Müller-Hermann situated the work carefully between these competing frames while seeking to achieve critical success as a woman composer. The Whitmanesque vision of America that Müller-Hermann created would have also had a politically charged significance in both Austria and the U.S. in the period surrounding the work’s premiere.

In 5G scenarios, there are a large number of video signals that need to be processed. Multiobject tracking is one of the main directions in video signal processing. Data association is a very important link in tracking algorithms. Complexity and efficiency of association method have a direct impact on the performance of multiobject tracking. Breakthroughs have been made in data association methods based on deep learning, and the performance has been greatly improved compared with traditional methods. However, there is a lack of overviews about data association methods. Therefore, this article first analyzes characteristics and performance of three traditional data association methods and then focuses on data association methods based on deep learning, which is divided into different deep network structures: SOT methods, end-to-end methods, and Wasserstein metric methods. The performance of each tracking method is compared and analyzed. Finally, it summarizes the current common datasets and evaluation criteria for multiobject tracking and discusses challenges and development trends of data association technology and data association methods which ensure robust and real time need to be continuously improved.

AbstractGlyphosate-resistant (GR) Palmer amaranth continues to be challenging to control across the U.S. cotton belt. Timely application of POST herbicides and herbicides applied at planting or during the season with residual activity are utilized routinely to control this weed. Although glyphosate controls large Palmer amaranth that is not GR, herbicides such as glufosinate used in resistance management programs for GR Palmer amaranth must be applied when weeds are small. Dicamba can complement both glyphosate and glufosinate in controlling GR and glyphosate-susceptible (GS) biotypes in resistant cultivars. Two studies were conducted to determine Palmer amaranth control, weed biomass, and cotton yield, as well as to estimate economic net return when herbicides were applied 2, 3, 4, and 5 wk after planting (WAP). In one experiment POST-only applications were made. In the second experiment PRE herbicides were included. In general, Palmer amaranth was controlled at least 98% by herbicides applied at least three times regardless of timing of application or herbicide sequence. Glyphosate plus dicamba applied at 4 and 5 WAP controlled Palmer amaranth similarly compared to three applications by 8 WAP; however, yield was reduced 23% because of early-season interference. The inclusion of PRE herbicides benefited treatments that did not include herbicides applied 2 or 3 WAP. Glyphosate plus dicamba applied as the only herbicides 5 WAP provided 69% control of Palmer amaranth. PRE herbicides increased control to 96% for this POST treatment. Economic returns were similar when three or more POST applications were applied, with or without PRE herbicides.
