This report of the American Dairy Science Association Committee on the Nomenclature, Classification, and Methodology of Milk Proteins reviews changes in the nomenclature of milk proteins necessitated by recent advances of our knowledge of milk proteins. Identification of major caseins and whey proteins continues to be based upon their primary structures. Nomenclature of the immunoglobulins consistent with new international standards has been developed, and all bovine immunoglobulins have been characterized at the molecular level. Other significant findings related to nomenclature and protein methodology are elucidation of several new genetic variants of the major milk proteins, establishment by sequencing techniques and sequence alignment of the bovine caseins and whey proteins as the reference point for the nomenclature of all homologous milk proteins, completion of crystallographic studies for major whey proteins, and advances in the study of lactoferrin, allowing it to be added to the list of fully characterized milk proteins.

This article examines the impact of social capital on philanthropy. Based on extensive information on individuals’ embeddedness in various dimensions of social capital gathered in the Social Capital Community Benchmark Survey, two measures of social capital are extracted from the data via factor analysis. One relates to individuals’ associational networks; the second relates to their trust in others and in their community. These measures are then incorporated into models of religious giving, secular giving, and volunteering. The estimates confirm the importance of social capital in explaining the generosity of individuals. When social capital is included in giving equations, the direct influences of human capital (education) and religiosity fall, raising the question of whether previous understanding of their importance as determinants of giving and volunteering was overstated or, alternatively, whether the extent to which religion and education foster personal philanthropy by fostering associational networks and norms of trust and cooperation has been under-appreciated.
