This paper intends to examine the level of consumers＇ brand origin recognition accuracy of high-involved products （referred to hereafter as BORAx）, investigate the factors facilitating BORAHI, and trace the implications of BORAHHI on brand evaluation, especially in cellphone industry. The BORAHI is measured in China through cellphones as the product object and a consumers＇ cognitive model of BORAhn is built. The paper concludes that： Chinese urban consumers have a fairly high BORAHHI; better-educated consumers demonstrate higher BORAHHI scores for foreign brands; rmle consumers have higher BORAHI scores than fe-rrules consumers; consumers lower in ethnocen-trism exhibit higher level of BORAHI for foreign brands, and ethnocentrism has no effect on BO-RAHI for local brands; international experience is not related to BORAHI for local brands; internation-al experience is positively related to education and income respectively, but it is negatively related to age. This research finds that the consumer behavior in China, one of emerging markets, is significantly different from that in developed countries.展开更多

Objective: To evaluate the effects of CR on testosterone and luteinizing hormone (LH) levels and sexual behaviors of male mice. Methods: Forty 3-month-old male mice, 22 - 25 g, were randomly allocated into four equal groups (n = 10 per group): the control group and three CR exposure groups including 8-hour group, 16-hour group and 24-hour group. Each mouse received different dose of CR exposure for 30 consecutive days. Sexual behaviors and testosterone and LH levels in serum were measured at the end of experiment. Furthermore, we also observed the weights of reproductive organs of each group, including testis, epididymis and seminal vesicle. Results: The mount latency and intromission latency in 24-hour group were significant higher than the control (both P < 0.01), while no obvious changes were seen in 8-hour group and 16-hour group (all P > 0.05). No difference in ejaculation latency existed among each group after the experiment (all P > 0.05). The frequency of mount and intromission in 24-hour group was statistically significantly lower than that of the control group (P < 0.05 and P < 0.01, respectively). No obvious change in the frequency of mount and intromission of the 8-hour group and 16-hour group was seen (all P > 0.05). Only the copulatory efficacy in the 24-hour group was statistically lower than the control group (P < 0.05). The serum levels of testosterone and LH in the 24-hour group were obviously higher than the control group (testosterone level: P < 0.05;LH level: P < 0.01). No significant differences were seen among the other two experimental groups and the control group (all P > 0.05). After the exposure of CR, the changes in the weights of sexual organs in the 24-hour group were significant compared with the control (testis weights, relative testis weight, epididymis weight, the weight of seminal ves展开更多
