研究分为问卷调查与实验研究两部分。首先,40名女性和33名男性完成有关自感配偶价值评价(SPMV)和择偶偏爱策略的问卷调查,问卷调查结果是实验研究中数据分析的基线。其次,第二部分实验开始后,被试会得到实验者编造的他人潜在择偶对象的积极正面评价,其目的在于提高被试的SPMV。可以假设,男性的 SPMV 与随意性行为的认同或追求有正相关,男性 SPMV 的提高将会更加偏爱短期的性策略;女性 SPMV 与随意性行为不存在相关,女性 SPMV 的提高不会改变女性的性策略。研究结果显示,SPMV 高基线水平的男性更加认可随意性行为,男性 SPMV 的提高与短期策略选择的增加有关。另外,SPMV 提高,而不是一般自尊的提高,与择偶策略的改变具有相关。本研究结果没有证实,与长期稳定的性关系相比,SPMV 的基线水平或是提高与女性对随意性行为的认同或追求之间存在相关。

本文译自盖文·宾汉姆在2010年春季拉丁美洲货币研究中心会议上的发言。文章认为:对于央行在维护金融稳定的职能过程中应充当什么样的角色目前还含糊不清,这显然不正常。因此给央行赋予一种更加明确和宽泛的维护金融稳定的职权对于央行的正常履职是十分必要的。这需要考虑什么是适当的金融稳定目标,对于不同的责任需要什么样的职权、手段和组织结构;还要考虑央行在保持其行政职能的独立性时,需要哪些机制来保证。
