Maximizing versus satisficing: Happiness is a matter of choice.

Can people feel worse off as the options they face increase? The present studies suggest that some people--maximizers--can. Study 1 reported a Maximization Scale, which measures individual differences in desire to maximize. Seven samples revealed negative correlations between maximization and happiness, optimism, self-esteem, and life satisfaction, and positive correlations between maximization and depression, perfectionism, and regret. Study 2 found maximizers less satisfied than nonmaximizers (satisficers) with consumer decisions, and more likely to engage in social comparison. Study 3 found maximizers more adversely affected by upward social comparison. Study 4 found maximizers more sensitive to regret and less satisfied in an ultimatum bargaining game. The interaction between maximizing and choice is discussed in terms of regret, adaptation, and self-blame. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

Does completing a craving questionnaire promote increased smoking craving? An experimental investigation.

The authors evaluated whether completing a multi-item assessment of smoking craving (the Questionnaire of Smoking Urges [QSU]) promoted increases in smoking craving. A sample of 39 regular smokers was randomly assigned to 1 of 3 manipulations (each of 3 min duration): (a) complete the QSU–Brief (10 items), (b) complete a noncraving questionnaire that was structurally identical to the QSU–Brief (scale-based control), and (c) a time-based control. Participants responded to an oral question assessing their degree of craving immediately before and after the manipulations. Results indicated that the QSU did not promote increases in craving compared to the 2 control conditions. Despite continuing debate over the most appropriate self-report measure of craving, investigators who use the QSU–Brief can be reasonably sure that the scores that result are not biased due to reactivity effects.

地铁杂散电流对衬砌耐久性影响及防护的探讨

城市地下铁道以其不受气候条件的影响和安全快捷的运输特点，在解决我国城市交通运输问题中发挥着骨干作用。在促进城市经济和社会协调发展的同时，地下铁道的建设和运营也对城市的环境和结构物的安全产生影响，其中由地下铁道运营中产生的杂散电流腐蚀就是影响结构物安全与耐久性的重要因素。文章分析了地下铁道隧道中杂散电流的分布状况，给出了区间隧道内杂散电流的近似计算方法，探讨了产生杂散电流的原因和影响因素，在此基础上，初步分析了杂散电流腐蚀对隧道衬砌混凝土结构耐久性的影响以及地下铁道杂散电流的防护措施。
