Rapid globalization has led to many studies of cross-cultural issues and their implications for management. As China＇s importance in the international economy rises, the level of international business cooperation continues to increase. This paper first identifies differences in the cultural orientations of Chinese and Canadians entering the job market and then examines how these orientations are related to their perceptions of the criteria employers use when hiring. The analyses show that the cultural differences are not consistent with Hofstede＇s previous work. Further, there are significant differences in the qualities that are considered important when seeking a job. The results of this study increase mutual understanding and improve business relationships between the two countries.

Background To compare the preventive effects of levetiracetam and valproate on late-onset post-traumatic seizures in patients with traumatic brain injury(TBI).Methods A total of 95 patients with TBI were recruited from 2017 to *** were randomized into three groups:levetiracetam(LEV)group(n=30)receiving LEV treatment(500 mg,bid,po);valproate group(n=32)receiving sodium valproate(500 mg/d,once daily,po);and control group(n=33)receiving no anti-seizure *** and valproate were given to corresponding groups within seven days after TBI,and the administration lasted for one *** incidence of epilepsy and adverse events were evaluated at 7 days and 12 months *** The cumulative incidences of late post-traumatic seizures at the 12-month follow-up in the LEV,valproate,and control groups were 3.33%,12.50%and 15.63%,*** cumulative incidence of late post-traumatic seizures in the LEV group was significantly lower than those in the valproate and control groups(Pwas not significantly different from that in the control group(P>0.05).Conclusions LEV can reduce the cumulative incidence of late post-traumatic seizures,whereas valproate can not.

we present a novel confocal laser method （CLM） for precise testing of the dioptric power of both positive and negative intraocular lens （IOL） implants. The CLM principle is based on a simple fiber-optic confocal laser design including a single-mode fiber coupler that serves simultaneously as a point light source used for formation of a collimated Gaussian laser beam, and as a highly sensitive confocal point receiver. The CLM approach provides an accurate, repeatable, objective, and fast method for IOL dioptric power measurement over the range from 0 D to greater than ±30 D under both dry and in-situ simulated conditions.

Correlations among behavioral traits can generate trade-offs and constrain phenotypic evolution. Interspecific hybridization has the potential to alter behavioral trait correlations, but the effect of hybridization on suites of behavioral traits has received relatively little attention. we evaluated how natural hybridization changes the relationship between boldness （time of emergence and proportion of time out of shelter） and response to a simulated predator threat in swordtails （Teleostei： Xiphophorus）. In poeciliid fishes, bold individuals have increased survival in the presence of predators. This non-intuitive observation may arise as a result of bold individuals being more likely to engage in anti-predator behaviors. Contrary to our prediction, bold indi- viduals were less likely to perform a fast-start response to a predator threat. This correlation was consistent among populations and species but was only significant in hybrids. The observed correlation between boldness and anti-predator behavior could im- pact hybrid fitness and the evolvability of hybrid lineages. More generally, our findings suggest that hybridization could influence the integration of behavioral phenotypes, as has been amply documented for morphology. Animal personality and behavioral syndromes could therefore play an important role in the evolutionary fate of natural hybrids [Current Zoology 61 （4）： 596-603, 2015].

作者： Rong-Rong Zhao james w Fawcett Brain Repair Centre University of Cambridge

After spinal cord injury （SCl）, re-establishing functional circuitry in the damaged central nervous system （CNS） faces multiple challenges including lost tissue volume, insufficient intrinsic growth capacity of adult neurons, and the inhibitory environment in the damaged CNS. Several treatment strategies have been developed over the past three decades, but successful restoration of sensory and motor functions will probably require a combination of approaches to address different aspects of the problem. Degradation of the chondroitin sulfate proteoglycans with the chondroitinase ABC （ChABC） enzyme removes a regeneration barrier from the glial scar and increases plasticity in the CNS by removing perineuronal nets. Its mechanism of action does not clash or overlap with most of the other treatment strategies, making ChABC an attractive candidate as a combinational partner with other methods. In this article, we review studies in rat SCI models using ChABC combined with other treatments including cell implantation, growth factors, myelin-inhibitory molecule blockers, and ion channel expression. we discuss possible ways to optimize treatment protocols for future combinational studies. To date, combinational therapies with ChABC have shown synergistic effects with several other strategies in enhancing functional recovery after SCI. These combinatorial approaches can now be developed for clinical application.
