MS-123: Robert D. Hanson Papers

This collection is mainly comprised of letters and telegrams of the immediate Hanson family during WWII (1942-1946, with gaps), though there is a selection of letters to members of the family from other authors and a small group of letters written from 1904-1924 to Elizabeth and Henry Hanson from Elizabeth’s parents F. V. N. (Franklin Verzelius Newton) and L. T. ( Laura Trimble) Painter. In the sub-series of other letters addressed to Robert Hanson there are several letters pertaining to Robert’s admission to law school, the bar, and the army in addition to personal correspondence. Special Collections and College Archives Finding Aids are discovery tools used to describe and provide access to our holdings.

The History of Glatfelter Hall

A history of one of the oldest buildings on the Gettysburg College Campus, Glatfelter Hall. The paper covers the time period from the construction of the building in 1888 to after its first major renovation in 1929

Ethnic Conversions : Family, Community, Women, and Kinwork

According to the straight-line theory of assimilation, ethnic groups by the third or fourth generation should be entirely assimilated into mainstream society and should identify themselves as Americans. Yet there has been a resurgence of ethnicity among white ethnics in the United States that has led to a renewed interest in particular ethnic groups and their cultures. Third- and fourth-generation European Americans claim an ethnic identity even though their ties to their ancestral homeland may be tenuous. Lithuanian Americans in Kansas City, Kansas, in the 1950s, 1960s and 1970s would seem to provide support for the straight-line theory of assimilation, yet since the 1980s they have reconstituted themselves through the Lithuanians of America organization and are experiencing a renewal of their ethnic identity. The Lithuanian American community in Seattle, Washington, also experienced ebbs and flows in the activism and unity of its members. The community was active at the turn of the twentieth century, next revitalized by Lithuanian emigres following World War II, and then became active again in the late 1970s after a decade of inaction. Members of the two groups were given questionnaires in the early 1990s to address the ethnic identity fluctuations as well as the role of non-ethnics in the organizations. One of the more exciting findings from the surveys and from participant observation was the extensive role of ethnic converts in the Kansas City organization, and their lesser (but still significant) role in the Seattle Lithuanian-American community

The Importance of Families and Communities in Understanding Ethnicity

Social science provides us with a variety of theories that attempt to explain the dynamics of race and ethnicity. Many of these theories are concerned with the basic question of ethnic difference: its origins, persistence, and decline. In the contemporary literature on immigration to the United States and on how immigrants adjust to that relocation, assimilation and the persistence of ethnic identity have often been considered polar opposites.^1 Researchers, however, are beginning to find that both processes often occur simultaneously, as when immigrants become acculturated into American society but also maintain or even construct distinct ethnic identities, often symbolically. ^2 Even though a generation of immigrants may give up their ethnic identities, adopt the host language, and intermarry, their children or grandchildren may choose to renew ancestral ethnicities, and in so doing, may even contribute to the re-ethnicization of their parents as adults. Ethnicity (and ethnic identity), therefore, is both a conservative force as well as an agent of change.^3 The articles in this special issue of Ethnic Studies Review explore the dynamics of ethnicity in the United States and contextualize the experience of various groups within families and communities

Electro-optical device for monitoring wire size

Device recognizes variations in wire size and is being used during computer memory-plane fabrication. Decrease in wire diameter, due to stretching, permits removal of wire from memory-plant mold. Monitoring provides means of detecting imperfect wire and permits fabrication of computer memory plane to be stopped prior to its insertion into mold

Expansion of space station diagnostic capability to include serological identification of viral and bacterial infections

It is necessary that an adequate microbiology capability be provided as part of the Health Maintenance Facility (HMF) to support expected microbial disease events during long periods of space flight. The applications of morphological and biochemical studies to confirm the presence of certain bacterial and fungal disease agents are currently available and under consideration. This confirmation would be greatly facilitated through employment of serological methods to aid in the identification for not only bacterial and fungal agents, but viruses as well. A number of serological approached were considered, particularly the use of Enzyme Linked Immunosorbent Assays (ELISAs), which could be utilized during space flight conditions. A solid phase, membrane supported ELISA for the detection of Bordetella pertussis was developed to show a potential model system that would meet the HMF requirements and specifications for the future space station. A second model system for the detection of Legionella pneumophilia, an expected bacterial disease agent, is currently under investigation

A solid phase enzyme-linked immunosorbent assay for the antigenic detection of Legionella pneumophila (serogroup 1): A compliment for the space station diagnostic capability

It is necessary that an adequate microbiology capability be provided as part of the Health Maintenance Facility (HMF) to support expected microbial disease events and environmental monitoring during long periods of space flight. The application of morphological and biochemical studies to confirm the presence of certain bacterial and fungal disease agents are currently available and under consideration. This confirmation would be facilitated through employment of serological methods to aid in the identification of bacterial, fungal, and viral agents. A number of serological approaches are currently being considered, including the use of Enzyme Linked Immunosorbent Assay (ELISA) technology, which could be utilized during microgravity conditions. A solid phase, membrane supported ELISA for the detection of Legionella pneumophila, an expected disease agent, was developed to show a potential model system that would meet the HMF requirements and specifications for the future space station. These studies demonstrate the capability of membrane supported ELISA systems for identification of expected microbial disease agents as part of the HMF

Vision-based analysis of pedestrian traffic data

Reducing traffic congestion has become a major issue within urban environments. Traditional approaches, such as increasing road sizes, may prove impossible in certain scenarios, such as city centres, or ineffectual if current predictions of large growth in world traffic volumes hold true. An alternative approach lies with increasing the management efficiency of pre-existing infrastructure and public transport systems through the use of Intelligent Transportation Systems (ITS). In this paper, we focus on the requirement of obtaining robust pedestrian traffic flow data within these areas. We propose the use of a flexible and robust stereo-vision pedestrian detection and tracking approach as a basis for obtaining this information. Given this framework, we propose the use of a pedestrian indexing scheme and a suite of tools, which facilitates the declaration of user-defined pedestrian events or requests for specific statistical traffic flow data. The detection of the required events or the constant flow of statistical information can be incorporated into a variety of ITS solutions for applications in traffic management, public transport systems and urban planning
