Results of Primary Triangulation

Description: From introduction: The triangulation of the U. S. Geological Survey is executed solely for the primary control of topographic work upon scales not exceeding 1: 62500. The extreme of accuracy has therefore not been sought, but only such a degree of accuracy as to insure that the maximum accumulated error be imperceptible upon the maps.

Seismicity in Central North Africa at low magnitudes: A first look at the TAM event detected data base

Description: Teleseismic observations of seismicity in the central North Africa region show that the region is aseismic. This is true for earthquakes with a body wave magnitude greater than about 4 or so. For earthquakes with body wave magnitudes substantially below about 4, the teleseismic observations of seismicity in the central Sahara are incomplete since smaller earthquakes would probably not be detected and located by the current teleseismic monitoring networks. Only one known open seismic station has been operating in the central Sahara. This is the Tamanrasset (TAM) seismic station in southern Algeria. A simple analysis of data records from this station can be used to determine if the central Sahara is also relatively aseismic at magnitudes substantially below 4. That is the primary purpose of this study.

Taiwanese Cruisers in North America: An Empirical Analysis of Their Motivations, Involvement, and Satisfaction

Description: Cruise travel has become very popular worldwide. The North American cruise market is the world's biggest. Asian countries are among the fastest-growing outbound market for cruise travel. The Taiwanese cruise market has grown substantially. However, few research studies have examined Taiwanese travelers' motivation to experience a cruise vacation, and their satisfaction with the experience. Primary data was collected from a convenience sample of Taiwanese tourists who had been on North American cruise tours. Survey respondents were first time cruisers, over 40 years old, married, and had a Bachelor's degree, or higher. Push and pull motivational factors were identified. Respondents were influenced by recommendations from media and people. Respondents were satisfied with tangibles, cleanliness, food choices and selection, and responsiveness of staff. An overwhelming majority of cruisers would re-visit and recommend this trip. Implications for researchers and practitioners are suggested.

Phytochemial Society of North America 50th Anniversary Meeting

Description: The Phytochemical Society of North America will have its 50th anniversary meeting from December 10 through 15th, 2011, on the big island of Hawaii. The society has a long tradition in the study of plant biochemistry, chemistry, natural products (whether for commodity chemicals, food and fiber sources, renewable energy, pharmaceuticals, nutraceuticals and other bioactive substances). The meeting, being a very special celebration, is anticipated to attract a very broad range of researchers drawn from worldwide locations. This is also reflected in the international composition of our organizing and scientific program committees. We are now finalizing speakers for the PSNA 50 conference which has a variety of scientific themes, including biofuels/bioengineering, transcriptome profiling, metabolism and metabolomics, and new characterization technologies/methodologies. A most important part of our PSNA 50 conference is to provide opportunities for graduate students and postdoctoral fellows to present their research findings and exchange ideas with scientific colleagues. In this regard, the bulk of the funding in support of this conference is anticipated to come from sponsorships (industry, foundations, and so forth) and registrations which are currently underway. It is essential, however, that we strongly encourage the participation of both young graduate students and postdoctoral fellows at our historic meeting. In order to do this, we are requesting financial support from BES to help partially defray travel and registration costs to support 10 graduate students and 10 postdoctoral fellows in BES relevant areas of research. PSNA has a long history of supporting young scientists, including yearly graduate student and PDF competitions for best paper/poster awards. Support from BES would thus build on our previous successes, and enable a much broader and larger group of students/postdoctorals than at previous meetings.

Korean Studies in North America 1977-1996: A Bibliometric Study

Description: This research is a descriptive bibliometric study of the literature of the field of Korean studies. Its goal is to quantitatively describe the literature and serve as a model for such research in other area studies fields. This study analyzed 193 source articles and 7,166 citations in the articles in four representative Korean and Asian studies journals published in North America from 1977 to 1996. The journals included in this study were Korean Studies (KS), the Journal of Korean Studies (JKS), the Journal of Asian Studies (JAS), and the Harvard Journal of Asiatic Studies (HJAS). Subject matters and author characteristics of the source articles were examined, along with various characteristics such as the form, date, language, country of origin, subject, key authors, and key titles of the literature cited in the source articles. Research in Korean studies falls within fourteen broad disciplines, but concentrated in a few disciplines. Americans have been the most active authors in Korean studies, followed closely by authors of Korean ethnicity. Monographic literature was used most. The mean age of publications cited was 20.87 and the median age of publications cited was 12. The Price Index of Korean studies as a whole is 21.9 percent. Sources written in English were most cited (47.1%) and references to Korean language sources amounted to only 34.9% of all sources. In general, authors preferred sources published in their own countries. Sources on history were cited most by other disciplines. No significant core authors were identified. No significant core literature were identified either. This study indicates that Korean studies is still evolving. Some ways of promoting research in less studied disciplines and of facilitating formal communication between Korean scholars in Korea and Koreanists in North America need to be sought in order to promote well-balanced development in the field. This study ...

Studies on the Drumming Behavior of North American Stoneflies (Plecoptera)

Description: Drumming behavior is described for the first time in 16 North American species of Plecoptera, and signals of a 17th species, Isogenoides zionensis, are further detailed. The effective distance over which drumming signals may be transmitted was tested for four communication modes. Results indicate that substratum vibrations are far superior to sound in the transmission of drumming signals, and that dense substrates such as rocks are poor channels for signal transfer. Long communication periods between stonefly pairs of Taeniopteryx burksi resulted in some alterations from initial signaling characteristics.

Past Climate Variability and Change in the Arctic and at High Latitudes

Description: This Climate Change Science Program Synthesis and Assessment Product addresses current capabilities to integrate observations of the climate system into a consistent description of past and current conditions through the method of reanalysis. In addition, the Product assesses present capabilities to attribute causes for climate variations and trends over North America during the reanalysis period, which extends from the mid-twentieth century to the present. This Product reviews Past Climate Variability and Change in the Arctic and at High Latitudes. Paleoclimate records play a key role in our understanding of Earth's past and present climate system and in our confidence in predicting future climate changes. Paleoclimate data help to elucidate past and present active mechanisms of climate change by placing the short instrumental record into a longer term context and by permitting models to be tested beyond the limited time that instrumental measurements have been available. Recent observations in the Arctic have identified large ongoing changes and important climate feedback mechanisms that multiply the effects of global-scale climate changes. As discussed in this report, paleoclimate data show that land and sea ice have grown with cooling temperatures and have shrunk with warming ones, amplifying temperature changes while causing and responding to ecosystem shifts and sea-level changes.
