关于直径为5的图脆弱度的一个注记(Ⅱ)

The line persistence of a graph G, p1 (G) is the minimum number of lines which must be removed to increase the diameter of G. In Ref. [ 7 ] ( J. Shanghai Univ., 2003,7(4) :352-357), we gave a characterization of graphs of diameter five with P1 ( G ) ≥ 2. In this paper we will show that each of the 8 special graphs Xi ( i = 1,2,3,4,5,6,7,8 ) listed in condition (2) of Theorem 1 in Ref. [ 7 ] can not be deleted. Therefore the results we obtained in Ref. [ 7 ] can not in general be improved.

Dolores Huerta,the United Farm Workers,and people power: Rhetorical participation in Latina/o/x suffrage and social movements

ABSTRACT

Dolores Huerta, co-founder of the United Farm Workers Union, was and still is involved in a number of social justice causes, including voter participation. Since her days working at the Community Service Organization in the 1950s, she has long advocated for registering and organizing voters as part of a broader strategy to enfranchise Mexican, Mexican American, and other historically marginalized groups. This essay explores a few brief examples of her calls to get out the vote and participate in social movements more broadly to address the deep-seated problems of “citizenship excess” that face Mexican, Mexican American, and other immigrant communities (as well as many others) in the United States. In addition, Huerta has strongly advocated for “people power” as a way to get marginalized people into activism, especially those with intersectional identities related to race, ethnicity, gender, class standing, sexuality, and political orientations.
