Alterations to the inventory of about 24 000 species and infraspecific taxa of bryophytes and vascular plants in southern Africa are reported for the year 1988. The inventory, as currently maintained in the Taxon component of the PRECIS system, contains the accepted name for each taxon, synonyms previously in use as accepted names during the past half-century, and literature references necessary to identify species in each genus and to establish the synonymy. The inventory is updated as new research affecting plant classification in southern Africa is published. During 1988 there were 744 alterations, affecting about 3% of the total number of taxa.

Alterations to the inventory of about 24 000 species and infraspecific taxa of bryophytes and vascular plants in southern Africa are reported for the year 1987. The inventory, as presently maintained in the Taxon component of the PRECIS system, contains the accepted name for each taxon, synonyms previously in use as accepted names during the past half-century, and literature references necessary to identify species in each genus and to establish the synonymy. The inventory is updated as new research affecting plant classification in southern Africa is published. During 1987 there were 678 alterations, representing about 2,8% of the total number of taxa.a

Alterations for the year 1986 to the inventory maintained in PRECIS are reported for bryophytes, pteridophytes and monocotyledons, and for a few dicotyledons. For the cryptogams and monocots there are 77 newly described species or infraspecific taxa, 27 names brought back into use, and nine species newly reported for southern Africa, resulting in 113 additions to the total list of species. Five species were removed because they were mistakenly recorded from the area. Seventy-five names have gone into synonymy, there are 52 new combinations, and there are 35 orthographic corrections, resulting in 237 alterations to the list of species. The total of 355 additions, deletions and alterations represents about 5% of the total species and infraspecific taxa for the cryptogams and monocots.

Additions and alterations to the inventory of about 26 000 plant taxa in southern Africa are reported for the period from February 1990 to February 1991. In this period a total of 1 080 alterations have been recorded. These changes result from the continual surveying of taxonomic literature received by the library of the National Botanical Institute.

Evolutionary Perspectives

Evolutionary perspectives on human behavior are almost as old as the science of psychology itself. A new brand of functionalism has emerged; it draws inspiration from developments in evolutionary biology in the past half-century. This chapter offers an overview of evolutionary biology as applied to human psychology. An ecological niche is discussed, and the critical issue of the nature of the niche humans entered and defined is addressed. Unusually, individuals’ fitness was highly dependent on their ability to attract, form, and maintain cooperative coalitions with others and harness the competencies of others to their own. Several broad, evolution-inspired proposals about human social behavior are described, illustrating how evolutionary perspectives offer integrative understanding of psychological phenomena and generate new research programs. Individual differences from an evolutionary perspective are addressed. Evolutionary perspectives, rather than representing alternatives to social or cultural perspectives, offer a means to construct foundationally integrative personality and social psychology.

AbstractThe recent racial reckoning has challenged scholars to recover Black voices that have been erased from historical accounts. This essay is my reflections on the challenges I faced in conducting research on African voices in politically and racially charged settings in Lesotho and South Africa over the past half century. After the political atmosphere began changing in South Africa in 1990, I served the individuals and communities I write about by rectifying historical injustices such as returning a holy relic to a religious group, the Israelites, and facilitating the return of remains of Nontetha Nkwenkwe from a pauper’s grave in Pretoria to her home.

Evolutionary Perspectives

Evolutionary perspectives on human behavior are almost as old as the science of psychology itself. Functionalists such as James, Dewey, and Angell, however, lacked explicit evolutionary theories and methodologies to inspire generative research programs, and their movement dissipated. Today, a new brand of functionalism has emerged, one that draws its inspiration from massive developments in evolutionary biology in the past half-century. This chapter has several aims. First, it offers an overview of evolutionary biology as applied to human psychology. Second, it discusses the concept of an ecological niche, and addresses the critical issue of the nature of the niche that humans entered and defined. This niche has the unusual feature that individuals’ fitness was highly dependent on their ability to attract, form, and maintain cooperative coalitions with others and, hence, to harness the competencies of others to their own competencies. Third, it describes several broad, evolution-inspired proposals about human social behavior, which illustrate how evolutionary perspectives offer integrative understandings of psychological phenomena and generate new research programs. Fourth, it addresses individual differences from an evolutionary perspective. Rather than representing alternatives to social or cultural perspectives, evolutionary perspectives offer means by which to construct a personality and social psychology that is foundationally integrative.

Japan and the United States, the world’s largest economies for most of the past half century, have very different immigration policies. Japan is the G7 economy most closed to immigrants, while the United States is the large economy most open to immigrants. Both Japan and the United States are debating how immigrants are and can con-tribute to the competitiveness of their economies in the 21st centuries. The papers in this special issue review the employment of and impacts of immigrants in some of the key sectors of the Japanese and US economies, including agriculture, health care, science and engineering, and construction and manufacturing. For example, in Japanese agriculture migrant trainees are a fixed cost to farmers during the three years they are in Japan, while US farmers who hire mostly unauthorized migrants hire and lay off workers as needed, making labour a variable cost.

Here I survey a sample of the essays and reviews on the sciences of the long eighteenth century published in this journal since it was founded in 1969. The connecting thread is some historiographic reflections on the role that disciplines—in both the sciences we study and the fields we practice—have played in the development of the history of science over the past half century. I argue that, as far as disciplines are concerned, we now find ourselves a bit closer to a situation described in our studies of the long eighteenth century than we were fifty years ago. This should both favor our understanding of that period and, hopefully, make the historical studies that explore it more relevant to present-day developments and science policy. This essay is part of a special issue entitled “Looking Backward, Looking Forward: HSNS at 50,” edited by Erika Lorraine Milam.
