Review of \u3ci\u3eToward a More Perfect Union: The Settlement of Union Township, Clay County, Kansas\u3c/i\u3e by James R. Beck

James R. Beck laments the fact that he cannot tell us why the early settlers bought and sold land in Union Township. Although his microscopic land history can illuminate what land was acquired-as well as how, when, and by whom-he says only social histories provide the flesh of human stories to the bones of deed and mortgage details that are recorded in dusty courthouse record books. I see no need for apology. Beck deserves our gratitude for sweeping away the dust and revealing the underlying structure of settlement in northcentral Kansas. The chief subject here is the variety of means by which 23,000 acres of the Public Domain in Clay County were slowly but steadily acquired over four decades by private individuals and families. More than half of the settlers were homesteaders. Beck shows us that, despite the sentimental aura that has surrounded this federal program, it was a complex bureaucratic process that surely tried the patience of the pioneers. Other methods of obtaining land included the use of military land warrants, purchase of railroad land, payment in cash, abiding by the terms of the Timber Culture Act of 1873, and buying land the sale of which helped finance public schools

Asian-American Elderly: A Review Of The Quality Of Life And Social Service Needs

This paper briefly reviews the historical, cultural, and socio-economic factors that affect and define the lives of Asian-American elderly. A close examination of the present quality of life of Asian-American Elderly is made to determine if there are differences between that population and other populations. This paper provides information about existing social services and a summary of culturally relevant social work intervention. In conclusion, the paper underscores the urgent need for additional data collection regarding the Asian-American elderly that will help guide appropriate policy decisions and social services for this neglected group

Solar source regions of 3HE-rich particle events

Hydrogen alpha X-ray, and metric and kilometric radio data to examine the solar sources of energetic 3He-rich particle events observed near earth in association with impulsive 2 to 100 keV electron events were applied. Each 3He/electron event is associated with a kilometric type 3 burst belonging to a family of such bursts characterized by similar interplanetary propagation paths from the same solar active region. The 3He/electron events correlate very well with the interplanetary low frequency radio brightnesses of these events, but progressively worse with signatures from regions closer to the Sun. When H alpha brightnings can be associated with 3He/electron events, they have onsets coinciding to within 1 min of that of the associated metric type 3 burst but are often too small to be reported. The data are consistent with the earlier idea that many type 3 bursts, the 3He/electron events, are due to particle acceleration in the corona, well above the associated H alpha and X-ray flares

Continuing data analysis of the AS/E grazing incidence X-ray telescope experiment on the OSO-4 satellite

The work to correct and extend the calculation of the theoretical solar X-ray spectrum produced during earlier OSO-4 data analysis is reported along with the work to formulate models of active regions, and compare these models with the experimental values. An atlas of solar X-ray photographs is included, and solar X-ray observations are correlated with the solar wind

Fast drift kilometric radio bursts and solar proton events

Initial results of a comparative study of major fast drift kilometric bursts and solar proton events from Sep. 1978 to Feb. 1983 are presented. It was found that only about half of all intense, long duration ( 40 min above 500 sfu) 1 MHz bursts can be associated with F 20 MeV proton events. However, for the subset of such fast drift bursts accompanied by metric Type 2 and/or 4 activity (approximately 40% of the total), the degree of association with 20 MeV events is 80%. For the reverse association, it was found that proton events with J( 20 MeV) 0.01 1 pr cm(-2)s(-1)sr(-1)MeV(-1) were typically (approximately 80% of the time) preceded by intense 1 MHz bursts that exceeded the 500 sfu level for times 20 min (median duration approximately 35 min)

The Relationship of Coronal Mass Ejections to Streamers

We have examined images from the Large Angle Spectroscopic Coronagraph (LASCO) to study the relationship of Coronal Mass Ejections (CMEs) to coronal streamers. We wish to test the suggestion (Low 1996) that CMEs arise from flux ropes embedded in a streamer erupting, thus disrupting the streamer. The data span a period of two years near sunspot minimum through a period of increased activity as sunspot numbers increased. We have used LASCO data from the C2 coronagraph which records Thomson scattered white light from coronal electrons at heights between 1.5 and 6R_sun. Maps of the coronal streamers have been constructed from LASCO C2 observations at a height of 2.5R_sun at the east and west limbs. We have superposed the corresponding positions of CMEs observed with the C2 coronagraph onto the synoptic maps. We identified the different kinds of signatures CMEs leave on the streamer structure at this height (2.5R_sun). We find four types of CMEs with respect to their effect on streamers: 1. CMEs that disrupt the streamer 2. CMEs that have no effect on the streamer, even though they are related to it. 3. CMEs that create streamer-like structures 4. CMEs that are latitudinally displaced from the streamer. This is the most extensive observational study of the relation between CMEs and streamers to date. Previous studies using SMM data have made the general statement that CMEs are mostly associated with streamers, and that they frequently disrupt it. However, we find that approximately 35% of the observed CMEs bear no relation to the pre-existing streamer, while 46% have no effect on the observed streamer, even though they appear to be related to it. Our conclusions thus differ considerably from those of previous studies.Comment: Accepted, Journal of Geophysical Research. 8 figs, better versions at http://www.science.gmu.edu/~prasads/streamer.htm
