Abstract： Anodic oxide films on Al-alloys were sealed by aluminum phosphate to further improve their corrosion resistance. Electrochemical impedance spectroscope (EIS) was used to study the effect of the sealing treatment on corrosion resistance of the anodic oxide films in comparison with those sealed with boiling water and cerium salt solution respectively. The results showed that, the aluminum phosphate coating was formed on the anodic oxide film sealed with aluminum phosphate, and it could provide the anodic oxide film the best corrosion resistance superior to those sealed with boiling water and cerium salt solution. Furthermore, the effectiveness of the aluminum phosphate treatment could last longer than that of sealing treatmants with boling water and cerium salt solution. This method could be a new sealing treatment for anodic oxide film on Al-alloys.

Abstract： The extant literature suggests that employees' perception of being trusted by their supervisors is important in the workplace, as such perception can lead to many positive work-related outcomes. Although we have understood how and why feeling trusted has consequences, little is known about its development. Overlooking how feeling trusted develops may limit its effective application to managerial practices, because it is only when felt trust is successfully triggered that it could lead to the establishment of trust relationship and ultimately affect employee behavior. As a perception derived from the processing of trust-related information, employees’ feeling trusted by their supervisors may not necessarily fit the supervisors' actual trust. Therefore, to better manage employees by making them feel trusted, supervisors as the trustors, should not only take the initiative to engage in trusting behaviors, but also consider how to make employees perceive their trust accurately. Drawing on the symbolic interactionist view and social information processing theory, we develop a conceptual model about the development of employees’ feeling trusted by their supervisors. According to the model, delegation and coaching are identified as two of the critical factors that influence employees’ feeling trusted by their supervisors. The effects of delegation and coaching on feeling trusted depend on the employee’s goal orientation, on the supervisor’s trustworthiness, and on the level of team anxiety. While employees’ perception of being trusted influences their loyalty and dedication, the amount of influence exerted is conditional on the management risks faced by their supervisors. By delineating how and when supervisory trusting behavior can make employees feel trusted and accordingly influence their work behaviors, the current research makes three important contributions both theoretically and practically. First, feeling trusted is not determined by the trustor or the trustee alone, but develops through interactions between the two parties. Although previous studies have examined the influence of leadership on feeling trusted by supervisors, they have not explained it from the perspective of trust interaction. We identify delegation and coaching as two types of supervisory trusting behaviors, through which supervisors can convey symbolic trust cues. By doing so, our study, theoretically, extends the understanding about the antecedents of feeling trusted by supervisors and, practically, offers new insights into what supervisors can do to make employees feel trusted. Second, although the development of feeling trusted by supervisors relies on social information processing, few studies have explored its internal mechanism. Based on social information processing theory, our research initiates a new dialogue on the mechanisms and boundary conditions regarding the development of feeling trusted by supervisors. We do not only focus on potentially positive and negative paths regarding trust information processing but also explore how information relevance (employee goal orientations) and credibility (supervisor trustworthiness) moderate those paths. The study of employee goal orientations is conducive to identifying the target employees for whom supervisory trusting behaviors are more likely to be effective, while the study of supervisor trustworthiness further clarifies the positive or negative influence that supervisors may have in trust information delivery and processing. Practically, this study provides important guidance for supervisors to manage the target employees by facilitating their feeling trusted in an effective manner. Third, by exploring the moderating effects of two negative team-level factors (team anxiety and management risk), our study enriches the understanding about the contexts of trust interactions between supervisors and subordinates. Practically, we provide implications for how supervisors can adopt trust management strategies in an environment full of high uncertainty and challenges.

Abstract： To evaluate the differences from 3 different regions by chemometrics and principal component content determinations, we established HPLC fingerprints of Aconiti Radix and its processed product, which provided a scientific basis for the quality control of Aconiti Radix from different regions before and after processing. The HPLC method was established on a Waters SunFire C18 (4.6 mm×150 mm, 5 μm). Acetonitrile-glacial acetic acid (0.2%) solution (triethylamine adjusted pH to 6.20) was adopted as the mobile phase for gradient elution. The flow rate was set at 1.0 mL·min-1, and with the detection wavelength of 235 nm. The fingerprints wereanalyzed by the software of “Similarity Evaluation System for Chromatographic Fingerprint of Traditional Chinese Medicine”. The discriminant analysis of hierarchical cluster analysis (HCA), principal component analysis (PCA), orthogonal partial least squares-discriminant analysis (OPLS-DA) and partial least squares-discriminant analysis (PLS-DA) were employed, and combined with chemometrics and the determination results of principal components. The results were as follows: (1) HPLC fingerprints of 15 batches of Aconiti Radix and its processed product from 3 areas were established, 25 and 14 common fingerprint peaks were calibrated in 15 batches of raw and processed, 6 peaks were identified by the mixed reference product. They were benzoylmesaconitine (peak 16), benzoylaconitine (peak 17), benzoylhypaconitine (peak 18), mesaconitine (peak 21), hypaconitine (peak 22), aconitine (peak 23). (2) Chemometrics showed that 30 batches of samples were clustered into two categories, 15 batches of raw products were classified into 3 classes, 15 batches of processed products were classified into 3 classes. Six components containing mesaconitine and hypaconitine may be the markers of the quality difference between them. (3) The content determination results of principal components changed in varying degrees before and after processing, and the determination results of some principal components in Sichuan Jiangyou producing area before and after processing were significantly higher than those in the other two producing areas. The fingerprint method which established in the study is accurate, repeatable, and reliable. Furthermore, combined with chemical pattern recognition, it could be used for the quality control of Aconiti Radix and its processed product from different regions.

Abstract： One of the key elements for firms to develop stably is a high level of employees’ identification with their organizations. Employees’ innovative behavior is the cornerstone of firms’ innovation. However, there are inconsistent research findings about the influence of organizational identification on employees’ innovative behavior. The normative conflict model provides a theoretical lens for deep understandings of their relationship. According to this model, organizational identification has a dual impact (i.e. promotive and prohibitive) on innovative behavior through two disparate paths (i.e. dissatisfaction of the status quo and conforming to the status quo); employees’ perceptions of normative conflict is a crucial condition to trigger their dissatisfaction of and conforming to the status quo; leaders’ expectations and support for employees’ innovative behavior play moderating roles in the process whereby organizational identification promotes and prohibits employees’ innovative behavior.
