A great number of papers and notes have been written on the root maggots attacking cabbage, cauliflower, turnip, and radish in Canada and the United States during the past 75 years. These deal chiefly with the occurrence, life-history, and control of the cabbage maggot, Hylemya brassicae (Bouché), or species which have been misidentified as that species. The Canadian work has followed the lead of Gibson and Treherne (1916), but in spite of the accumulation of information on the life-history of the species, on cultivation methods, and on insecticides, the pests of these cruciferous plants remain as noxious as ever.

Although this is a common insect in many parts of the United States, it is not generally found in great numbers in any locality, and, notwith standing its general distribution, the various staes of the insect seem not to have been describe or figured.While I am not yet able to clear up all the points in its history, I have studied the insect in all its stages, though I have not reared it from the egg to maturity, on account of the time required for it to develop—in all probability three years.

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 In doing so, it explores key historical documents, including the Balfour Declaration, Article 22 of the Covenant of the League of Nations, and UN Security Council Resolution 242, none of which included the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.

This chapter explores how recent discourses of motherhood and nation are deeply enmeshed and mutually constitutive. I trace a brief history of reproductive politics in the United States, clarifying how the project of nation building has consistently enlisted motherhood and worked to govern women’s reproduction through differential modes of surveillance and control. This chapter provides the historical and theoretical foundations for the book; it notes the precedents to homeland maternity while also elaborating on how contemporary alignments of motherhood and nation are distinct and specific to homeland security culture.

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.

Beginning with labor historians’ efforts to create a synthesis of the field in the 1980s, this essay explores the problem of working-class political fragmentation and the intellectual problems that posed for the generation of “new” labor historians. Looking to culture, class, community, and control as their themes, historians overlooked deeper problems in American class formation as well as the monumental complexity of discussing the history of class in the United States.
