Improved fallows in Eastern Zambia: history, farmer practice and impacts
No full text"The decline in soil fertility in smallholder systems is a major factor inhibiting equitable development in much of sub-Saharan Africa. Some areas fallow in order to strength soil fertility for later planting, but as populations increase, demand follows and continuous cropping becomes the norm and there is a reduction in yields. This case study summarizes the development of improved tree fallows by researchers and farmers in eastern Zambia to help solve the problem of poor soil fertility. Many farmers are finding that by using improved fallows, they can substitute relatively small amounts of land and labor for cash, which they would need to buy mineral fertilizer. The study has three phases: the historical background (phase 1); an assessment of problems, description of the technology, and how it was developed (phase 2); and how the improved fallows practices were disseminated and spread (phase 3). This paper will describe each phase, the goals, and results." Authors' AbstractSouthern Africa, africa south of sahara, Crop yields,
Richard Dorson (interview)
No full textThis interview is included in the American Folklore Society Oral History Project held at the Archive of Folk Culture, American Folklife Center, Library of Congress, Washington, D.C. In this item, Richard M. Dorson is interviewed by Richard Reuss at the American Folklore Society annual meeting in Nashville, Tennessee for the American Folklore Society Oral History Project. Biography/History note: Richard M. Dorson, folklorist, author, and educator, was born in New York City in 1916 and died in 1981. He earned his B.A., M.A. and Ph.D. at Harvard University and taught at Harvard and Michigan State University before becoming professor of history and folklore at Indiana University where he founded its Folklore Institute in 1963 and became the first director and first chair of the Folklore Department at Indiana University in 1978. This collection consists of 1 sound tape reel (40 min.) : analog, 7 1/2 ips, 2 track, mono. ; 7 in. It was originally recorded on November 2, 1973 at the American Folklore Society annual meeting in Nashville, Tennessee by Richard Reuss on a Sony audiocassette. This is a first-generation copy

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Trade with the Pacific Rim
No full textDuring the 1990s the economies of East Asia were among the fastest growing in the world, and appeared poised for further expansion. Yet as American trade with these economies grew, so too did the U.S. trade deficit with the region. International trade and open markets are critical to the wellbeing of the U.S. economy, but the ballooning trade deficit caused widespread concern among American policymakers, including President Clinton, who placed renewed emphasis on increasing American competitiveness and bolstering exports. The United States' role in the 1993 Asia-Pacific Economic Cooperation Conference emphasized the importance of balancing American trade with the Pacific Rim countries, whose imports, although sizable, continued to fall short of exports to the U.S. What is causing the growing imbalance of trade with the East-Asian economies, and how can the U.S. ensure that the benefits of trade go both ways? Hosted by Peter Krogh, and featuring James Fallows, Washington Editor of the Atlantic Monthly, and Ambassador Richard Solomon, former Assistant Secretary of State for East Asian Affairs.Discusses the growing U.S. trade deficit with the countries of the Pacific Rim and examines potential responses
Simultaneous interplanetary scintillation and Heliospheric Imager observations of a coronal mass ejection
No full textWe describe simultaneous Interplanetary Scintillation (IPS) and STEREO Heliospheric Imager (HI) observations of a coronal mass ejection (CME) on 16 May 2007. Strong CME signatures were present throughout the IPS observation. The IPS raypath lay within the field-of-view of HI-1 on STEREO-A and comparison of the observations shows that the IPS measurements came from a region within a faint CME front observed by HI-1A. This front may represent the merging of two converging CMEs. Plane-of-sky velocity estimates based on time-height plots of the two converging CME structures were 325 kms?1 and 550 kms?1 for the leading and trailing fronts respectively. The plane-of-sky velocities determined from IPS ranged from 420 ± 10 kms?1 to 520 ± 20 kms?1. IPS results reveal the presence of micro-structure within the CME front which may represent interaction between the two separate CME events. This is the first time that it has been possible to interpret IPS observations of small-scale structure within an interplanetary CME in terms of the global structure of the event
