Owners of small- and medium-sized farms are increasingly interested in engaging in agritourism and direct sales in order to increase income, provide family employment, and educate the public about agriculture, among other reasons. Prior research on agritourism operator motivations largely focuses on economic goals and benefits, while acknowledging the strong influence of non-economic factors. However, more research is needed to better understand the nuances and breadth of non-economic motivations underlying agritourism operator decisions. In addition, research on U.S. agritourism tends to be at the state level, which raises questions about overall national trends and inter-study comparability. To address these gaps, we analyzed transcripts from semistructured interviews with small- and medium-sized farm owners engaged in agritourism from five states across the U.S. We examined the results through the theoretical lens of Allport’s “contact hypothesis” in order to further understand how agritourism helps operators meet stated goals. Our results suggest that consistent with previous literature, nonmonetary motivations are high priorities for farmers engaged in agritourism. In particular, motivations related to community engagement/leadership and quality-of-life emerged as forceful and reoccurring themes. We found that although Allport’s contact hypothesis holds some important explanatory power for understanding agritourism operators’ community-related goals—including reducing prejudice and increasing understanding between farmers and consumers in relation to agriculture—increased inter-group contact also has potential to create new conflicts between farmers and neighbors related to tourism. These findings have important implications for future research as well as for policies and programs aimed at supporting agritourism.

This essay will attempt to explain why it has taken so long for the city/state and public history organizations in Boston to begin to embrace the heritage of its Latino/a communities in public history projects. It will contextualize early attempts in the 1970s and 1980s to develop and promote Latino/a public history projects and exhibits and will discuss changes that have occurred in the 1990s. The second part of the essay will discuss how issues of representation, power, and participation have been addressed by two recent projects that have attempted to incorporate Latino/a history in Boston. The city of Boston has been selected as a case-study for a number of reasons. First, Boston is one of a few cities in the U.S. where public history projects have national repercussions. The combination of a high concentration of institutions of higher education, and the city's attractiveness to visitors fascinated by the U.S. colonial, maritime and independence history makes Boston a national leader in the field of public history. Second, the situation in Boston -- where increased hostility towards immigrants, affirmative action, and bilingualism - is representative of recent trends in urban centers throughout the U.S and allows for important comparisons. Finally, the selection of Boston is significant because it breaks from traditional studies that limit Latino/a history issues to cities that have a larger percentage of Latinos/as in its population such as Houston, Los Angeles, Miami, and New York. Within the small field of Latino/a public history including case studies of cities such as Boston is crucial because Boston is probably more representative of national trends than are the large cities mentioned earlier.

Mutual Agreement

This program has been organized by the EMSA to commensurate the 50th anniversary of the experimental verification of the wave nature of the electron. Davisson and Germer in the U.S. and Thomson and Reid in Britian accomplished this at about the same time. Their findings were published in Nature in 1927 by mutual agreement since their independent efforts had led to the same conclusion at about the same time. In 1937 Davisson and Thomson shared the Nobel Prize in physics for demonstrating the wave nature of the electron deduced in 1924 by Louis de Broglie.The Davisson experiments (1921-1927) were concerned with the angular distribution of secondary electron emission from nickel surfaces produced by 150 volt primary electrons. The motivation was the effect of secondary emission on the characteristics of vacuum tubes but significant deviations from the results expected for a corpuscular electron led to a diffraction interpretation suggested by Elasser in 1925.

Examination of sand grain surfaces from early Paleozoic sandstones by electron microscopy reveals a variety of secondary effects caused by rock-forming processes after final deposition of the sand. Detailed studies were conducted on both coarse (≥0.71mm) and fine (=0.25mm) fractions of St. Peter Sandstone, a widespread sand deposit underlying much of the U.S. Central Interior and used in the glass industry because of its remarkably high silica purity.The very friable sandstone was disaggregated and sieved to obtain the two size fractions, and then cleaned by boiling in HCl to remove any iron impurities and rinsed in distilled water. The sand grains were then partially embedded by sprinkling them onto a glass slide coated with a thin tacky layer of latex. Direct platinum shadowed carbon replicas were made of the exposed sand grain surfaces, and were separated by dissolution of the silica in HF acid.

Today it is estimated that one of every three women in the U.S. will have problems achieving pregnancy. 20-30% of these women will have some form of oviductal problems as the etiology of their infertility. Chronically damaged oviducts present problems with loss of both ciliary and microvillar epithelial cell surfaces. Estradiol is known to influence cyclic patterns in secretory cell microvilli and tubal ciliogenesis, The purpose of this study was to assess whether estrogen therapy could stimulate ciliogenesis in chronically damaged human fallopian tubes.Tissues from large hydrosalpinges were obtained from six women undergoing tuboplastic repair while in the early proliferative phase of fheir menstrual cycle. In each case the damaged tissue was rinsed in heparinized Ringers-lactate and quartered.
