Citizen science activity is growing rapidly around the world and diversifies into new disciplines with recent advances in technology. This expansion is accompanied by the formation of associations and networks dedicated to citizen science practitioners, which aim at supporting citizen science as a research approach. This chapter examines how four such organizations in the United States, Europe, Australia, and China have begun to take shape, and are working with citizen science communities and stakeholders in respective regions and globally. Challenges and future plans of these groups are also discussed. This chapter identifies three core roles of citizen science practitioner organization: 1) establishing communities of practitioners, 2) building expertise through sharing of existing and developing new knowledge, and 3) representing community interests. By focusing on this hitherto neglected phenomenon, the authors aim to stimulate further research, discussion and critical reflection on these central agents in the emerging citizen science landscape.

In this initial volume of a new series of "Advances," the editors state in the preface that their aim "is to provide a readable account of selected important developments [in clinical chemistry], of their roots in the allied fundamental disciplines, and of their impact upon the progress of medical science." The editors have drawn on eminent authorities from Australia, Sweden and Switzerland as well as Great Britain and the United States to contribute nine chapters on a wide variety of subjects. The reviews, which in general are of exceptional quality, provide a critical evaluation of important advances in methods of analysis and their clinical significance. In addition to much useful information on analytic techniques of value to the investigator, the reviews contain a wealth of information clearly and succinctly presented which reflect the authors' thorough syntheses of recent advances in their special fields. The extensive bibliographies include a large number of references in the foreign literature.

Despite recent advances in testing and treatment, the incidence of HIV/AIDS in the United States has remained stagnant with an estimated 56,300 new infections every year. Women account for an increasing proportion of the epidemic. The vulnerability of women to HIV stems from both increased biologic susceptibility to heterosexual transmission and also the social, economic, and structural disadvantages they often confront. This review describes the main reasons for the increased vulnerability of U.S. women to HIV transmission with particular emphasis on specific high-risk groups including: non-Hispanic blacks, women who use drugs, women with a history of incarceration, and victims of intimate partner violence. Although behavioral approaches to HIV prevention may be effective, pragmatic implementation is often difficult, especially for women who lack sociocultural capital to negotiate condoms with their male partners. Recent advances in HIV prevention show promise in terms of female-initiated interventions. These notably include female condoms, non-specific vaginal microbicides, and antiretroviral oral and vaginal pre-exposure prophylaxis. In this review, we will present evidence in support of these new female-initiated interventions while also emphasizing the importance of advocacy and the political support for these scientific advances to be successful.

Three world telecommunications conferences, called by the United States, were held throughout the spring and summer of 1947 to deal with urgent problems resulting from dislocations of war and recent advances in the several fields covered by the International Telecommunications Union. At a preliminary Telecommunications Conference, held at Moscow in September, 1946, representatives of China, France, the United Kingdom, USSR, and the United States had decided that existing telecommunications conventions and regulations required revision to meet present needs; for this purpose the conferences were called.

Michael White put chromosomes into evolutionary thinking and made a primary contribution to the emerging neo-Darwinian evolutionary synthesis. He emphasized cytogenetic systems and argued that genic and chromosomal evolution were of seminal importance in the process of speciation and evolution. His major scientific contribution was Animal Cytology and Evolution (1945), a book that summarized, analysed and synthesized current information on animal chromosomes. White held a somewhat parallel place in cytogenetics to C.D. Darlington whose book Recent Advances in Cytology (1932, 1937) had earlier synthesized observations on plant chromosomes. For many years from the late 1930s there was a lively competition between these two industrious, innovative and self-assertive figures. Undoubtedly, White found satisfaction greater than that of science alone when ( contra Darlington) he described an achiasmate meiosis in a mantid during his first period of research in the United States in the late 1930s.
