Page Four NSF GRANT 'Grinnell College has been a- Warded a tissue grant by the National Science Foundation for biology research. The grant, which was eiiec- iive Sept. 1 for a two~year per- lad, is for research on “The Ei- iect of Manipulation of Social Structure on the Rate of Popu- lotion IncreaseJn Small Mam< mals” by Karl DeLong, assist- mt professor of biology. Dr. DeLong, who uses lei'al Kwiid) house mice in his re- search, has been working in this area for five years. This particular project grew out of research conducted ior his Ph- D. dissertation, } HETTLINGER (Continued from Page 1) man and woman involved is A complex matter. Lester Kiriren- dall, in a sandy 0! this prob- lem, found that in several in- stances a relationship was weakened, or even broken, as a result of intercourse. How this happens is not clear. When it happens, the girl is oiten in a difficult position: many men who have no qualms about re- ducing the supply of virgins prefer to marry girls with no sexual experience, or no exper- ience with men other than themselves. S e r i o u s misunderstandings can result from physiological and psychological differences between the sexes, unless the intentions of the individuals cori- SCARLET AND BLACK cemed are completely under- stood. Hettlinger cited a Kin- sey study showing that the need of men for physical sata isiaction in sex reaches its peak in the late teens, while this peak in women occurs about ten years later. This means that the college- age man is likely to be con- cerned largely with sexual de- sire, while the girl will more probably be thinking in terms of a lasting relationship. while her gestures may be intended to show her affection for him, he might interpret them as sig- niiying sexual excitement. Be- ing excited himself, he may find it impossible no stop when she asks him to. While he can get a purely physical enjoyment from sex, she cannot, and may be disgusted by sexual actions which do not express love. if he sincerely loves her, he must keep these differences in mind if he is to avoid forcing his desires on her. Despite medical advances in the area of birth control, one premarital sexual liaison in five results in an accidental pregnancy. Since those who are most promiscuous are usually the most careful in their con- traceptive measures, they are less likely to get "in trouble" than those who don’t really plan to have intercourse, but prog- ress to it from petting. The ethical problems of stu- dent sexual relationships. says Hettlinger, can be directly at- tributed to the mixedup moral- ity of the older generation.

Unable to explain their attitude in any reasonable manner, pars ents leave their children with' vague feelings that sex is wrong while Madison Avenue constant: ly portrays it as something glamourous and attractive. In revolt against this double standard, peer group pressure among students often results in the formation of a "conformity Di sexual freedom." Even slus dents who do not accept tradi~ tional mores, however. tend to reject promiscuity and insist on “high standards of love and loyalty." Hettlinger is Chairman of the Department of Religion at Ken. yon College, Gambier, Ohio. Born in England. he studied at Cambridge University. He has taught ln Toronto, Canada, and Canterbury, England. in l959, Hettlinger came to the U.S. for graduate work at Yale Univer. sity, and a year later he was appointed Chaplain and Asso- ciate Professor of Religion at Kenyon. In the fall of 1963, he gave a series of lectures on “Sex and the Single Student", and the enthusiastic reaction from students and faculty led him to expand the talks into his book, Living with Sex. H0 intends to write another book, aimed at high-school students, to be called Growing Up with Sex. DANFORTH 0N CATALYSTS 'A catalyst is a chemical agent which acts to speed up specific reactions. They are found in the cells of plants and animals, and take part in th- metabolic process. Catalyst! are also used by industry in the manufacture of such products as ammonia and plastics, and in the cracking of petroleum to gasoline. This last reaction was the Iubject of last week's lecture by Dr. Joseph Danforth of the chemistry department. Dr, Danforth worked for Universal Oil Products before coming to Grinnell, and has conducted re— search here on the petroleum catalysts, the silica-aluminas. He Spoke on his most recent attempts to discover the site on the molecule where catalytic cracking takes place, using as lecture aids models of [he crystal structure of the zeoiile clays (the same as the struc- ture of the modern synthetic silicaraluminas). In his research, Dr. Danforth found, purely by chance, that only upon the addition of water would his catalysts react (in this case with isopropyl hen- zene). The degree oi reaction was recorded by a device cre- ated by Dr. Dantonh which measured the quantity of the reaction products that came off. He concluded that the wat- er removes phenol (benzene plus a hydrogen atom) and leaves a hydroxide radical at the specific site of activity. This site is as yet undeter- mined. Dr. Daniorth will publish nit- Qr the final confirmation of his results by means of infra-red analysis.
