Psychometric properties are critical to making decisions about choosing a screening instrument. The purpose of the present study was to examine the psychometric properties of the student risk screening scale for internalizing and externalizing behaviors (SRSS-IE). Participants included 3145 students and their teachers. Item-level analyses of the current sample supported the retention of all items. The internal consistency of the SRSS items ranged from 0.83 to 0.85. Convergent validity between the SRSS-IE and a well-established screening tool, the strength and difficulties questionnaire (SDQ), was found for the total score (r = 0.70). Additionally, the results of this study demonstrate strong social validity, suggesting the SRSS-IE to be a useful and functional screening tool. We conclude that the SRSS-IE is a valid and reliable instrument for assessing the level of emotional and behavioral difficulties among elementary students.展开更多

This paper aims to specify the potential and current risks and uncertainty that may be met in international logistics, then seeks some practical methods to dodge and solve them.展开更多

First, enterprises do not necessarily share the same expectation for future demand of a promising industry. Second, in its model, overcapacity is explained as a deviation from equilibrium under the incomplete information hypothesis, which is in fact nothing but normal in a market economy. The prime reason for overcapacity resides in the fact that local governments are engaged in a subsidy competition to attract investment. We endeavor to illustrate the following via modeling： the subsidy effect produced by local government＇s offering of cheaper land and matching loans results in less investment from companies. Under this circumstance, enterprises channel a disproportionate amount of funding to building production capacity, which overloads the entire industry. To address the problem, reforms are needed in land property, environmental protection policies, and financial and fiscal systems.展开更多
