The present study empirically investigated the psychometric properties of the Chinese version of the Weinstein Noise Sensitivity Scale-Short Form （CNSS-SF）, the widely used inventory measuring individual differences in noise perception.Methods In total, 373 Chinese participants （age = 21.41 ± 3.36） completed the online, anonymous questionnaire package. Examination of the CNSS-SF＇s reliability （internal consistency）, factorial validity through validation and cross-validation, nomological validity and measurement invariance across gender groups were undertaken.Results The Cronbach alpha coefficients and composite reliabilities indicated sufficient reliability of the CNSS-SF. Two confirmatory factor analyses （CFA）, in two randomly partitioned groups of participants, substantiated the factorial validity of the scale. The nomological validity of the scale was also corroborated by the significant positive association of its score with the trait anxiety score. Measurement invariance of the CNSS-SF was also found across genders via multi-group CFA.Conclusion Though not without limitations, findings from the present research provide promising evidence for the utility of the scale in measuring noise sensitivity among the Chinese population. The availability of the CNSS-SF can promote research related to environmental noise and health in China, as well as facilitate cross-cultural comparisons.展开更多

In view of these problems,this paper analyzes the feasibility of regulating individual actions of professional vegetable farmers by administrative measures. It is partly because of imperfect laws and regulations and partly because of Shandong Province satisfying applicable conditions of regulating individual actions of professional vegetable farmers by administrative measures. On the basis of these,it comes up with following recommendations: ( 1) in professional vegetable planting regions,townships should set up vegetable quality and safety committee; ( 2) villages should establish " five vegetable farmer households mutual assistance and joint guarantee system" for vegetable quality and safety; ( 3) it should implement vegetable real-name system and traceability system; ( 4) it should implement vegetable farmer training system.展开更多
