想拿世界冠军的重庆"阿甘"

——你是啥子? ——冠军. ——啥子冠军? ——世界冠军. 每当马俊才在训练中坚持不住的时候,教练姜舟就会向他喊话. 三级智力残疾的马俊才今年18岁,在重庆市特殊教育学校读高二,是校田径队400米跑种子选手,也是教练姜舟心目中"阿甘"式的人物,坚韧、执着、善良、热心. 起初,学校打算培养马俊才做失明长跑运动员的陪跑员.姜舟在训练时,要求队员围绕操场按照一分钟跑一圈的节奏跑,谁知马俊才一跑就跑了半个小时,若不是姜舟喊停,他还没有停下来的打算.从此,"阿甘"这个名字在重庆市特殊教育学校不胫而走.     

Incentives to move up: Effects of pay gaps between levels on employee performance

Employees of a certain rank are motivated by the pay gap between them and the levels above (upward comparison), and the pay gap between them and the levels below (downward comparison). In some cases, employees face multiple upward comparisons such as immediate and subsequent upward comparisons. We hypothesise that upward comparison matters more than downward comparison, and in the case of multiple upward comparisons, the immediate one matters more than the subsequent ones. We also hypothesise that the pay gap effect resulting from the upward/downward comparison ought to be non‐linear in that performance increases with pay gap size at a decreasing rate. The results from two empirical studies, namely, a longitudinal field study and a laboratory experiment, largely support our hypotheses.     

Managerial Agency Costs of Socialistic Internal Capital Markets: Empirical Evidence from China

This study provides empirical evidence of managerial agency costs in socialistic internal capital markets. Listed Chinese companies are required to disclose the amount of resources that are reallocated to other firms of the parent company, which provides us with a direct measure of the socialistic subsidization of weak member firms by strong member firms within a business group. We hypothesize that in strong member firms, managerial compensation is less sensitive to firm performance because cross‐subsidization makes it difficult for group CEOs to hold the managers in strong firms accountable for their own firms' performance, and also increases the noise in performance measures. We also hypothesize that socialistic cross‐subsidization results in an increase in managerial agency costs of strong member firms due to the low pay‐performance sensitivity and low incentive to work hard. We document empirical results that are consistent with these two predictions.

不同施钙水平下AMF对刺槐养分吸收的影响

采用盆栽实验研究不同施钙水平和接种不同丛枝菌根真菌(arbuscular mycorrhizal fungi,AMF)对刺槐生长状况及矿质养分吸收的影响。结果表明:适量施Ca能促进刺槐对氮和磷的吸收,当施Ca量保持在0.1~0.2g·L-1时,刺槐全氮和全磷含量在AMF、Ca的共同作用下达到峰值,但施Ca抑制了刺槐对钾的吸收。
