Although the quantity of children's literature about Africa has been increasing rapidly in recent years--probably more has been published since 1960 than in the preceding three decades--the total volume is small and mediocre. Children's literature in this discussion refers to books written especially for children up to twelve or thirteen years of age. Somewhat over half the books which have been written for this age group are geographies, animal stories, and factual compendia with titles likeFirst Book of Liberia, Getting to Know Tanganyika, Land and People of South Africa, and so on. Young persons are likely to use such books in connection with school assignments or purely for pleasure (in the case of animal stories), but they will gain little understanding of African peoples and cultures from them.

The smaller segment of children's books about Africa is comprised of storybooks and factual presentations of African history and contemporary African life. Some of these books are sufficiently attractive to catch the attention of library users and of children whose parents are affluent enough to buy books for them. But do these books help create an understanding of the peoples and cultures of Africa? This question is especially pertinent since school curricula still devote relatively little attention to Africa, despite its increased importance on the world scene, and television, radio, movies, and other mass media to which children have access often do little or nothing to promote an understanding of Africa and its people.

The Boston University African Studies Program inaugurated a program for the United States Government in June 1959 when an orientation and training course for International Cooperation Administration (the predecessor of the Agency for International Development) career personnel to be assigned to African posts was undertaken. A special staff was appointed to administer the program under the direction of the Director of the African Studies Program. In 1961 the Development Research Center was formally established within the African Studies Program with responsibility for administering contract activities. John D. Montgomery, who was in charge of contract activities from 1960 to 1963, was succeeded as Director of the Development Research Center by John L. Fletcher, Jr., Professor of Government at Boston University. Other members of the Center's staff have included Edouard Bustin, Associate Research Professor of Government; Wilbert J. LeMelle, Assistant Research Professor of Government; John W. Sommer, Research Assistant; and Claudia W. Moyne, Research Associate. Regular staff members of the African Studies Program also participate in the work of the Development Research Center by delivering lectures and giving informal instruction.

During the period of the first contract, 140 career employees studied at Boston University. The program for the first group of employees included seven months of study, part of which was at Boston University and part in Europe and Africa. For the second group of employees, trained in 1960, a shorter period of study included work in Boston as well as a European phase at Oxford, London, Brussels, and Paris. For the third group there was a seven-week's program conducted entirely in Boston. Subsequent groups received four weeks of instruction in Boston. In addition to the lectures and published written materials, the course also included the study and discussion of special case studies in technical assistance and group exercises in the design and analysis of foreign aid programs for selected countries.

El presente texto hace parte de una corriente contemporánea de los estudios latinoamericanistas enfocada en el análisis de la navegación y las tecnologías náuticas nativas. El artículo presenta una revisión bibliográfica actualizada sobre los estudios mayistas enfocados en este tema y se inserta en las discusiones recientes. En el artículo se presenta el documento titulado “Discursos de Fray Gabriel de Salazar” escrito en 1620, y se analiza con el fin de acercarse a los conocimientos náuticos mayas del siglo diecisiete. En específico, se comenta acerca de la existencia de guías y pilotos locales, la elaboración de mapas, la construcción de embarcaciones y la comunicación del área maya con redes globales de navegación. La rica información aportada por el documento de Salazar permite apreciar la dependencia que los europeos tenían de las tecnologías náuticas y las tripulaciones mayas. Por último, se presentan algunas reflexiones sobre la navegación en el área maya y la historia náutica en América.

Students interested in the history of Liberia have been hampered by the dearth of serious studies on Africa's first republic. With few noteworthy exceptions, published works on Liberia can be grouped into two rather broad categories. The first consists of works which tend to be too journalistic in concept and execution to satisfy the demands of serious scholarship. The second includes a variety of memoir-like collections of reminiscences and observations recorded by individuals stationed at one time or another in Liberia while engaged in educational, missionary, or developmental programs. Much of the published material in both categories is useful, and indeed quite valuable, for it provides a good deal of information not readily found elsewhere. Yet, while informative, these books do not constitute a body of scholarly work which the serious student of West Africa would wish to have available.

One work which must have a place on the relatively brief list of trust-worthy books of reference relating to Liberia is the exhaustive compilation of basic documents prepared by the distinguished international jurist, C. H. Huberich. Paradoxically, it appears that it was this important work which discouraged many historians from searching further for basic source materials, for Huberich noted that most official Liberian documents were destroyed during a violent storm in Monrovia. Writers on Liberian affairs who accepted Huberich's statement as the final word on the subject seem not to have attempted to utilize unpublished Liberian government papers in their research. Even those researchers who have, in recent years, had sufficient interest to probe into this alleged disappearance of the Liberian archives, or who were desirous of determining the extent of archival materials which might have survived the disaster, were undoubtedly discouraged by ambiguous replies from Monrovia in response to their inquiries.

The conference, sponsored by the African Research Committee and the African Studies Group of the University of Wisconsin--Milwaukee, was held June 2-4, 1966, at the Kenwood Conference Center, Milwaukee. Conferees were as follows: D. W. Griffin (University of California, Los Angeles); Peter C. W. Gutkind (McGill University): Ruth Simms Hamilton (Iowa State University); George Jenkins (University of Wisconsin--Milwaukee); G. Wesley Johnson (Stanford University); John Paden (Northwestern University); Michael Safier (University of Wisconsin-Milwaukee); Henry J. Schmandt (University of Wisconsin--Milwaukee); W. M. Swanson (Yale University); and Alvin Wolfe (Washington University).

African urban studies are on the verge of escape from scarcity into bulky unintelligibility. At least sixteen books are being prepared by Americans for publication; most of them are single-instance studies by junior scholars, although six of them will present comparable materials gathered according to the “Bohannan plan.” (See African Urban Notes, I [April 1966], 1). In addition, some thirty Americans and Africans are presently in Africa or writing dissertations based on field research, and at least twenty more Americans are planning field research. Furthermore, the ARC conferences on unemployment, the West Indian Ocean area, geography, and migration have recommended still more urban research. Although this does not mean that a surfeit is threatened in any sector of urban studies, African urban research will probably be marked for some time by increasing descriptive affluence and continuing theoretical poverty. The essential need in this area of African studies is to provide for more meaningful development of a sizable movement whose momentum seems assured for the immediate future.

American scholars doing research in African literature sometimes have trouble locating the books they need. It is easy enough to get one's hands on African literary works published in England or America, but how does one get hold of material published in Africa -- e.g., Onitsha market chapbooks, early Lovedale or Morija press publications, or works in vernacular languages published by literature bureaus and small mission presses? Fortunately, for the older titles once can search through several published library catalogs -- Library of Congress (1942-1952), UCLA (1963), Berkeley (1963), the Schomburg Collection of the New York Public Library (1962), the African collection in the Moorland Foundation at Howard University (1958), Northwestern University's African collection (1962) -- and for the newer titles one can consult the National Union Catalog or the Joint Acquisitions List of Africana issued since 1961 by the Northwestern University Library. However, because these reference works do not list the older titles which libraries have acquired in recent years, one can never be certain that a particular African literary work is unavailable in the United States.

The mission was designed in part as a follow-up and in part as a complement to Professor Philip D. Curtin's research liaison visit to western Africa in 1965 on behalf of the Association. Senegal, Liberia, Ivory Coast, Tchad, and Cameroun were revisited. The previously unvisited Central African Republic, Dahomey, Niger, and Upper Volta were added to the itinerary. Difficulties in flight scheduling and unexpected delays during the trip ruled out the planned visits to Gabon and Togo.

The goals of the mission were as follows: (1) to establish or renew contacts with universities, research institutes, appropriate government authorities, African and expatriate researchers, and American scholars currently engaged in research in Africa; (2) to make known the existence of the Research Liaison Committee (and sometimes, as it turned out, of the ASA as well) as a two-way clearing house for Africanist research information; (3) to establish more regular means of exchanging information with institutions in Africa on current and planned research, so as to make possible some informal coordination of research plans among scholars; (4) to determine the existing formal procedures (if any) for researchers from abroad; and (5) to convey back to the Africanist community in the United States some of the feelings, attitudes, and suggestions from these countries.

The United States Department of Commerce is the largest data collecting organization in the world. Its Bureau of the Census has the monumental job every ten years of conducting a population census; its Office of Business Economics has the important task of measuring the national income and computing the balance of international payments and is also nationally known for a family of publications including the scholarly monthly SURVEY OF CURRENT BUSINESS.

These data are intended primarily to provide statistical guidelines relative to the course of the domestic economy. However, a different kind of data collection activity is carried on regularly by the Department in the Bureau of International Programs and the Bureau of International Business Operations. These two bureaus have primary responsibility within the department for the promotion of United States foreign commerce and private international investments. Both are new organizational units created as of August 8, 1961 to replace the former Bureau of Foreign Commerce, and both are under the supervision of the Assistant Secretary of Commerce for International Affairs who is, in turn, responsible directly to the Secretary of Commerce. In announcing this reorganization in the department's international affairs' responsibilities, Secretary Hodges stated that the Commerce Department must “fulfill our role in formulating U.S. foreign economic policy especially as it affects the American business community. … We want to be in a position to advise both business and government on the imminent changes in world trade and investment resulting from regional economic integration, from the threat of the Sino Soviet Bloc, and from our own economic growth. We need better methods to evaluate and set upon developments abroad which have an impact on the U.S. foreign and domestic trade.”

Suspensions of microswimmers exhibit distinct characteristics as compared with those of passive particles because the internal particles are in a state of spontaneous motion. Although there have been many studies of microswimmer suspensions, not many have carefully considered the hydrodynamics. Hydrodynamics becomes particularly important when discussing non-dilute suspensions, because the lubrication flow generates a large force when the swimmers are in close proximity. This paper focuses on hydrodynamics and describes the transport phenomena of microswimmer suspensions, such as migration, collective motion, diffusion and rheology. The paper is structured to progressively scale up from a single microswimmer to collective motion to a macroscale continuum. At each scale, the discussion also evolves from dilute to concentrated suspensions. We first introduce natural swimming microorganisms, artificial microswimmers and mathematical models, as well as the fundamentals of fluid mechanics relevant to microswimmers. We then describe the migration of microswimmers by taxis, where microswimmers respond passively or actively to their hydrodynamic environment. Microswimmers exhibit collective motions, the mechanism of which is discussed in terms of hydrodynamics. The spreading of microswimmers is often diffusive, and the diffusion coefficient is much larger than for passive particles. Similarly, the mass diffusivity in microswimmer suspensions is higher due to their swimming activity. We explain these macroscopic diffusion properties. The viscosity of microswimmer suspensions can be higher or lower depending on the characteristics and orientation of the microswimmers. We describe the rheological properties of microswimmer suspensions in shear flow and Poiseuille flow. Finally, current issues and future research perspectives are discussed.

Almost 50 years have passed since Sartori introduced to the world one of the most famous innovations in the history of political science: a new party systems typology. Despite many criticisms and refinements since then, Sartori's typology still constitutes, as stated by Peter Mair in 1990, “the most effective and exhaustive framework within which to contrast the properties of different party systems”. In the current research note, and taking into consideration that previous typologies have not yet been that successful, we propose a new classification of party systems – which not only embeds the notion of polarization into the typology, but also allows us to populate the “polarized pluralist” type beyond Sartori’s “centre-based” (Italian) model – in Asia, a continent almost completely ignored by Sartori in his seminal work. Using an original dataset that includes the most important characteristics of party systems in the region and building on Sartori's original conceptualization, we examine to what extent party systems in Asian democracies, both contemporary (Bhutan, East Timor, India, Indonesia, Japan, Malaysia, Mongolia, Nepal, Pakistan, Philippines, South Korea, Sri Lanka and Taiwan) and historical (Bangladesh 1991–2006, Kyrgyzstan 2010–2020, Myanmar 2015–2020 and Thailand 1992–2013), have changed. Our discussion of a new party system typology is particularly relevant and important to Asia, as its many new democracies still need to shift from plurality electoral rules adopted during the early post-independence periods to more mature, power-dispersing political institutions that accommodate their rich ethnic and religious diversity, as it happened in Europe after the World Wars.
