The Effect of Implicit Person Theory on Performance Appraisals.

Four studies examined whether implicit person theory (IPT) regarding the malleability of personal attributes (e.g., personality and ability) affects managers' acknowledgment of change in employee behavior. The extent to which managers held an incremental IPT was positively related to their recognition of both good (Study 1) and poor (Study 2) performance, relative to the employee behavior they initially observed. Incremental theorists' judgments were not anchored by their prior impressions (Study 3). In the 4th study, entity theorists who were randomly assigned to a self-persuasion training condition developed a significantly more incremental IPT. This change in IPT was maintained over a 6-week period and led to greater acknowledgment of an improvement in employee performance than was exhibited by entity theorists in the placebo control group.

Hydrogen pressure dependence in the ring-opening reactions of propylcyclobutane over Pd/SiO2 catalyst

Temperature dependence and the effects of hydrogen pressure on the rate and regioselectivity were studied in the ring opening of propylcyclobutane over a low-dispersion Pd/SiO₂ catalyst. At a certain composition (1.33 kPa of propylcyclobutane and 20 kPa of H₂) the reaction rate versus temperature curve was found to pass through a maximum. At each temperature the ring opened selectively (or exclusively at 423 K) in the sterically more hindered direction over the clean surface as well as over the steady-state catalyst, yieldingn-heptane as the major product. The hydrogen pressure versus turnover frequency curves were of saturation type for both products over the initial surface at 523 K. Over the steady-state surface, however, the reaction mechanism changed: ring-opening rate versus hydrogen pressure curve passed through a maximum forn-heptane, while it remained of saturation type for 3-methylhexane. For rationalizing the high regioselectivity towardn-heptane formation, the anchoring effect of the propyl side-chain was suggested.

栅状表面液晶盒的光学特性

栅状表面基板对液晶分子有特殊的锚定作用,其锚定的强度和易取方向与栅状表面的几何参数相关。两块预先处理的栅状表面基板可以制成液晶显示器件,其光学特性也与栅状表面的几何参数相关。文中基于Frank弹性理论和栅状表面基板的等效锚定能公式研究了外加电压下此种液晶盒的光学特性,并通过计算机模拟得到了不同栅状表面液晶盒的电光曲线,且与栅状表面液晶盒的闽值电压进行了比较。
