    Family Values, Social Capital and Contradictions of American Modernity

    Contemporary American social and political discourses have integrated concerns about family values into the realm of debates about the associational life of social capital. In these discussions, theoretical and historical confusions about the relations between family and civil society run rampant. In this article, I first bring theoretical clarity to these social structures and the type of relations upon which they are predicated and, second, briefly historicize the relationships between an American idea of family and civil society. By tracing changes in popular understandings of family and civil society, I demonstrate that the modern family values movement spurns its Victorian roots by maintaining the nostalgic language for a life and family of old built around a Christian home, while embracing means and institutions, and even more importantly, a form of family, which belies the nostalgia. The family has now become an institution or association which can be sustained through instrumental interventions; it is no longer to do with the organic relations of sentiment remaining from some long-faded Gemeinschaft. The family and the Christian home ideal, which were at the center of American critiques of modernization, have ceased to be.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline

The definitive version was published in Marine Ecology 27 (2006): 54-65, doi:10.1111/j.1439-0485.2005.00053.x.This study provided the first comprehensive analysis of Atlantic horseshoe crab (Limulus polyphemus) fecundity. Limulus appear to be determinate spawners, maturing all their eggs for the breeding season before spawning begins. On average, larger females held a larger number of eggs (63,500) than smaller females (14,500). By the end of the breeding season there was an average of 11,600 mature eggs female-1 left undeposited, regardless of female size. Larger females laid a higher percentage of the eggs they contained. Thus they not only contain more eggs, but are more effective at laying them as well. Size of spawning females ranged from about 185-300 mm prosomal width, with by far the highest concentration in the mid-size ranges. Although on an individual basis large females carry and lay the greatest number of eggs, mid-size crabs as a group contributed more to the horseshoe crab population in Pleasant Bay because they were more plentiful (net fecundity was highest for mid-size crabs). These results have implications for the management of this important species, which is harvested for bait, scientific, and biomedical uses. Incorporation of these results into models and other management tools can help predict growth rates, effects of size-selective harvest, reproductive value, and stable stage distribution of populations.This project was partially funded by MIT Sea Grant 8247-5

    New White Etch Cracking resistant martensitic stainless steel for bearing applications by high temperature solution nitriding

    No full text
    White Etch Cracking (WEC) is a severe and unpredictable failure mode that has been frequently observed in, among others, bearings for wind energy applications. In this work a novel, patented, WEC resistant bearing steel solution is developed through high temperature solution nitriding, followed by a custom heat treatment. Conventional medium carbon, 13 wt% Cr martensitic stainless steels were subjected to the novel process to obtain a nitrogen-rich case. A series of soft annealing, austenitization, cryogenic and tempering treatments converted the nitrogen-rich region into a fine-grained case containing nano-sized precipitates. Test bearings and tribometer specimens were treated with the same sequence of treatments. These specimens were tested under two different accelerated WEC failure promoting conditions. In contrast to standard through-hardened bearing steel the nitrided specimens showed no WEC formation, not even after prolonged testing
