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.

We examine how charitable giving is influenced by who in the household is primarily responsible for giving decisions. Looking first at single-person households, we find men and women to have significantly different tastes for giving, setting up a potential conflict for married couples. We find that, with respect to total giving, married households tend to resolve these conflicts largely in favor of the husband's preferences. However, when the woman is the decision maker, she will still make a significantly different allocation of those charity dollars, preferring to give to more charities but to give less to each. We find our results give new insights into both issues of charitable giving and household decision making.

In this qualitative study, the authors examined the nature of resilience in people with chronic disabilities. Fifteen people with disabilities identified the factors that helped or hindered them at major turning points, and the triggers and resolutions to these turning points. Turning points were emotionally compelling experiences and realizations that involved meaning acquired through the routes of belonging, doing, or understanding the self or the world. The major protective factors were social support, traits such as perseverance and determination, and spiritual beliefs. Three new protective processes were identified: replacing a loss with a gain (transcending), recognizing new things about oneself (self-understanding), and making decisions about relinquishing something in life (accommodating). These protective factors, processes, and ways in which people with disabilities draw sense and meaning in life have important implications for service delivery.

To obtain a molecular basis for the similarities and dissimilarities in the functional, chemical, and biochemical properties between beta-casein and the other caseins, a predicted three-dimensional model is presented. The predicted structure was assembled using molecular modeling techniques, as well as secondary structural prediction algorithms, in conjunction with global secondary structural information from Raman spectroscopy. To add validity to this model, the structure was refined using energy minimization techniques to diminish the likelihood of structural overlaps and energetically unfavorable van der Waals contacts arising from the large number of proline residues present in the beta-casein sequence. The refined model overall showed a loosely packed, asymmetrical structure with an axial ratio of 2:1. Hydrophobic side chains were uniformly dispersed over one end (C terminal) and the center surface of the structure; the other end (N terminal) was hydrophilic. The hydrophobic section also possessed a large loop through which water could easily travel. Such a suprasurfactant structure could account for the micellar type of hydrophobically driven self-association exhibited by beta-casein. Other chemical and biochemical data are in good agreement with the refined structure.
