标题:What Women And Men Should Be,Shouldn'T Be,Are Allowed To Be,And Don'T Have To Be: The Contents Of Prescriptive Gender Stereotypes
摘要:本文提出了一个四类框架,用于描述规范性性别刻板印象的内容.该框架区分了因为一个人的性别而加强的规定和禁忌,以及因为一个人的性别而放松的规定和禁忌.两项研究考察了这个框架在美国社会(第一项研究)和普林斯顿大学这个高度男性化的环境中(第二项研究)描述规范性性别刻板印象的效用.结果显示了传统性别规定在两个环境中的持续存在,但也揭示了每种性别在社会警惕和宽容方面的明显区别.此外,结果表明相对于社会标准,女性被看待得更积极,而男性则相反.我们考虑了这个框架对于研究对性别刻板印象异类和性别歧视反应的影响.

权利人:GOODYEAR TIRE & RUBBER
摘要:This invention disclosed a process for the synthesis of polyesteramides. By utilizing the phosphorus containing catalyst systems of the present invention, such polyesteramides can be synthesized at relatively low temperatures. The present invention specifically discloses a process for the synthesis of a polyesteramide which comprises polymerizing at least one diamine, at least one diol, and at least one dicarboxylic acid in the presence of (1) at least one acid acceptor; (2) at least one halogenated organic compound; and (3) at least one phosphorus containing compound selected from the group consisting of (a) triphenylphosphine, (b) triphenylphosphine oxide, (c) triphenylphosphine sulfide, (d) polymeric agents having pendant diphenylphosphine groups, (e) silicon-phosphorus compositions which contain at least one divalent oxygen atom which is bonded directly to a tetravalent silicon atom and a trivalent or pentavalent phosphorus atom; (f) compounds with the structural formula (C 6 H 5 ) 3 P=N-R, wherein R is a hydrogen atom or an alkyl group containing from 1 to 10 carbon atoms; and (g) compounds with the structural formula (C 6 H 5 )PR 1 R 2 wherein R 1 and R 2 can be the same or different, wherein R 1 is selected from the group consisting of alkyl groups containing from 1 to 10 carbon atoms and phenyl groups, and wherein R 2 is an alkyl group containing from 1 to 10 carbon atoms.

标题:Low temperature synthesis of condensation polymers
发明人：OGATA NAOYA
权利人:GOODYEAR TIRE & RUBBER
摘要:Condensation polymers of high molecular weight, such as polyesters, polyureas, and polyamides, are usually prepared at temperatures of 200° C. or greater. However, by utilizing the catalyst systems of the present invention, condensation polymers can be synthesized at much lower temperatures. The polycondensation catalyst systems of the present invention are particularly useful for synthesizing aliphatic polyesters, such as polyethylene terephthalate, from dicarboxylic acids and aliphatic glycols. The present invention more specifically discloses a process for the synthesis of an aliphatic polyester comprising polymerizing at least one dicarboxylic acid with at least one aliphatic glycol in the presence of (1) at least one phosphorus containing compound which contains at least one trivalent or pentavalent phosphorus atom which is bonded directly to at least one phenyl group, (2) an acid acceptor, and (3) at least one halogenated organic compound. It is preferred to utilize a polymeric agent having bound acid acceptor groups as the acid acceptor in the process of the present invention.
