Online Library Tutorials: A Literature Review

In 2009, the Journal of Web Librarianship published a literature review covering best practices for creating library online tutorials. These principles included (1) knowing the tutorial’s purpose, (2) using standards, (3) collaborating with others, (4) engaging students, and (5) conducting evaluations. The purpose of this current essay is to serve as an updated literature review, culling and synthesizing seven other pedagogical facets from newer literature: (1) technology updates, (2) tutorial maintenance and revision, (3) multimedia learning by gaming, (4) cognitive load theory and chunking, (5) adult education theory, (6) blended and flipped learning, and (7) the importance of ongoing engagement

Marital Exits and Marital Expectations in Nineteenth Century America

On April 10, 1991, Professor of Law, Hendrik A. Hartog of the University of Wisconsin Law School, delivered the Georgetown Law Center’s eleventh Annual Philip A. Hart Memorial Lecture: Meanings of Marriage: The Structure of Marital Expectations in Nineteenth Century America. Hendrik Hartog is the Class of 1921 Bicentennial Professor of the History of American Law and Liberty at Princeton University. He holds a PhD. in the History of American Civilization from Brandeis University (1982), a J.D. from the New York University School of Law (1973), and an A.B. from Carleton College (1970). Before coming to Princeton, he taught at the University of Wisconsin Law School (1982-92) and at the Indiana University (Bloomington) School of Law (1977-82). Hartog has spent his scholarly life working in the social history of American law, obsessed with the difficulties and opportunities that come with studying how broad political and cultural themes have been expressed in ordinary legal conflicts. He has worked in a variety of areas of American legal history: on the history of city life, on the history of constitutional rights claims, on the history of marriage, and on the historiography of legal change. He is the author of Public Property and Private Power: the Corporation of the City of New York in American Law, 1730-1870 (1983) and Man and Wife in America: a History (2000). He is the editor of Law in the American Revolution and the Revolution in the Law (1981) and the co-editor of Law in Culture and Culture in Law (2000) and American Public Life and the Historical Imagination (2003). Representative articles include “Pigs and Positivism” (Wisconsin Law Review, 1985); “The Constitution of Aspiration and ‘The Rights that Belong to us All’” (Journal of American History, 1987); “Mrs. Packard on Dependency” (Yale Journal of Law and the Humanities, 1988); “Abigail Bailey’s Coverture: Law in a Married Woman’s Consciousness” (in Law in Everyday Life, 1993); “Lawyering, Husbands’ Rights, and ‘The Unwritten Law,’ in Nineteenth-Century America” (Journal of American History, 1997); and “Llewellyn, Divorce, and Description” (in American Public Life and the Historical Imagination, 2003). He has been awarded a variety of national fellowships and lectureships, and for a decade he co-edited Studies in Legal History, the book series of the American Society for Legal History

Melting properties of radiation-induced Na and Cl2 precipitates in ultra-heavily irradiated NaCl

Exposure of NaCl to high doses of ionizing radiation leads to the formation of nano-particles of metallic Na, very small chlorine precipitates, vacancy voids, and dislocations. A useful way to monitor the stage of the damage formation process is measuring the latent heat of melting of the Na-particles (~100°C) and chlorine precipitates (-101°C). In this paper we will present data, showing that for doses in the range of TRad (1010 Gy) the concentration of radiolytic Na may become very large. Even in pure samples, we have converted more than 20% of all NaCl molecules into metallic Na and chlorine, but often higher percentages can be achieved. In this paper we will present new data obtained for ultra-high irradiation doses and a first attempt will be made to understand the results.
