A result on Hamiltonian line graphs involving restrictions on induced subgraphs

It is shown that the existence of a Hamilton cycle in the line graph of a graph G can be ensured by imposing certain restrictions on certain induced subgraphs of G. Thereby a number of known results on hamiltonian line graphs are improved, including the earliest results in terms of vertex degrees. One particular consequence is that every graph of diameter 2 and order at least 4 has a hamiltonian line graph

The Path of Most Resistance: The Long Road Toward Gender Equity in Intercollegiate Athletics

While sports have long played an important role in educating boys and young men in leadership, physical fitness and competitive skills, only recent- ly have girls and young women had the chance to benefit from athletic opportunities. Over two decades of experience with a federal statute pro- hibiting sex discrimination in school sports programs have brought important successes in opening doors for female athletes. However, enforcement of equal opportunity in this area has encountered strong resistance from the athletic establishment, which has fought efforts to equalize resources and opportunities for young women. Heightened enforcement of equal athletic opportunity in the 1990s has rekindled old opposition to basic notions of gender fairness in sports. React- ing to the recent successes of female athletes in the courts, both college foot- ball and other men\u27s sports advocates have taken the offensive in challeng- ing the law\u27s requirements, arguing that men are more interested in sports than women and therefore deserve the lion\u27s share of resources and opportu- nities. While such challenges have not succeeded, future progress toward gender equity in sports requires a renewed commitment to the underlying principle that female athletes are as deserving of sports opportunities as their male counterparts. This Article discusses the recent backlash against the legal requirements governing sex discrimination in intercollegiate athletic programs in the con- text of the history and enforcement of the law. Part I discusses the require- ments of the law, its legislative and interpretive history, and recent advances in enforcement. Part ..

A Defined Agar Medium for Genetic Transformation of \u3cem\u3eNeisseria meningitidis\u3c/em\u3e

Catlin, B. Wesley (Marquette University, Milwaukee, Wis.) and Gertrude M. Schloer. A defined agar medium for genetic transformation of Neisseria meningitidis. J. Bacteriol. 83:470–474. 1962.—An agar medium was developed for use in quantitative genetic studies of Neisseria meningitidis strain 15. It contains eight inorganic salts, sodium citrate, sodium lactate, arginine, cysteine, glycine, sodium glutamate, and purified agar. Abundant surface growth in the absence of supplemental carbon dioxide was obtained during 50 serial subcultures. A close correspondence was found between numbers of parental type colonies developing on the defined medium and on a complex medium. Cells subcultured serially three or four times on defined agar medium and placed directly into a solution of transforming deoxyribonucleic acid in defined liquid medium were susceptible to transformation without additional supplements. Of the treated population, 0.1 to 0.3% of the cells were transformed to streptomycin resistance
