Publicity has raised concern about the presence of polychlorinated biphenyls (PCBs) in breast milk. There are no known effects in children at levels found in people in the United States. In Kyushu, Japan, pregnant women who ingested cooking oil that was heavily contaminated with PCBs and other chemicals had small-for-gestational-age infants who had transient darkening of the skin. PCBs are stored in body fat and are not readily excreted, except in the fat of breast milk. In the past, PCBs have entered the body through a variety of foods. More recently, contaminated game fish and occupational exposures have been the main sources. The only women in the United States who may have been heavily exposed are those who worked with PCBs or who have eaten large amounts of sports fish from PCB-contaminated waters such as the Saint Lawrence Seaway. Unless women have a history of exposure to PCBs, they should be encouraged to breast-feed their infants as usual. When a well-documented history of exposure to PCBs is obtained and the mother wants to breast-feed her infant, the mother's PCB level could be measured in about three weeks' time. The advice of state health department officials should be sought in the rare instances when a high PCB level is found.

Abstract Because of its potential for fostering antisemitic stereotypes, in the twentieth century The Merchant of Venice has a history of being subject to censorship in secondary schools in the United States. While in the past it has often been argued that the play can be used to teach tolerance and to fight societal evils such as xenophobia, racism and antisemitism, I argue that this is no longer the case due to the proliferation of performance methods in the classroom, and the resultant emphasis on watching film and stage productions. Because images – particularly film images – carry such strong emotional valence, they have the capacity to subsume other pedagogical aspects of this drama in their emotional power and memorability. I therefore question whether the debate over teaching this play is truly a question of ‘censorship’, or simply educational choice.

This essay argues that what has been going on in Palestine for a century has been mischaracterized. Advancing a different perspective, it illuminates the history of the last hundred years as the Palestinians have experienced it. In doing so, it explores key historical documents, including the Balfour Declaration, Article 22 of the Covenant of the League of Nations, and UN Security Council Resolution 242, none of which included the Palestinians in key decisions impacting their lives and very survival. What amounts to a hundred years of war against the Palestinians, the essay contends, should be seen in comparative perspective as one of the last major colonial conflicts of the modern era, with the United States and Europe serving as the metropole, and their extension, Israel, operating as a semi-independent settler colony. An important feature of this long war has been the Palestinians' continuing resistance, against heavy odds, to colonial subjugation. Stigmatizing such resistance as “terrorism” has successfully occluded the real history of the past hundred years in Palestine.

A neglected part of the history of teaching sociology is the history of teaching high school sociology. The American Sociological Association's centennial in 2005 affords sociologists an opportunity to reflect on the teaching of sociology–anywhere and everywhere that it happens. In the spirit of contributing to the history of teaching sociology in the United States, this paper outlines the roughly 95-year history of the teaching of high school sociology. I rely upon published course descriptions written by high school sociology teachers and empirical studies conducted by academic sociologists. They demonstrate that past high school sociology courses have focused primarily on examining social problems and current events, and on promoting citizenship education. This remains the case today. I offer several reasons why the courses have looked as they have over the past 95 years, and conclude with four predictions about the future of teaching high school sociology.

Over the course of the past half century, the field of colonial Latin American history has been greatly enriched by the contributions of Father Stafford Poole. He has written 14 books and 84 articles and book chapters and has readily shared his knowledge at coundess symposia and other scholarly forums. Renowned as a historian, he was also a seminary administrator and professor of history in Missouri and California. Moreover, his background and formation are surely unique among priests in the United States and his story is certainly worth the telling.

This article provides a brief history of K–12 education testing in the United States from colonial America to the present. In early America, students were examined orally. After the mid-nineteenth century, written tests replaced oral presentations. In the late nineteenth century, graded schools gradually replaced the single-teacher, one-room schools. In the beginning of the twentieth century, standardized intelligence tests were increasingly used to categorize and promote students. State departments of education have played a larger role in local school funding and policies in the past hundred years. Since the 1960s, the federal government has expanded its involvement in national education while also promoting the role of states. During the past three decades, the federal government and states increased the use of high-stakes national testing with initiatives such as America 2000, Goals 2000, No Child Left Behind, and Every Student Succeeds.

Seeing in the last number of the Canadian Entomologist, a description of the egss of A. Luna, reminds me to ask of you the explanation of a curious circumstance in the life-history of one bred by me from the larva last year. I will premise that I am writing without my notes, and therefore cannot give figures accurately, but can give the facts. There may be nothing very strange about it, but two of the best entomologists in the United States inform me that it is entirely new to them. It is this:–Some time in the latter part of the summer of 1868 I took, feeding on walnut leaves, a mature larva of A. Luna; from which I did not houi to rear the mature insect, because I counted on the larva over twenty eggs like those of a Tachina, Underneath some of the eggs I could discern with a lens a minute opening through which the fly-larva had entered the body of the Luna larva. The skin of the latter was more or less discoloured under each egg, but under some-under many in fact there was a dense black spot, sometimes two lines in diameter.
