Effect of supervisor-subordinate Guanxi on employees work behavior: An empirical dynamic framework

Recently, the Chinese concept of guanxi (networks or business relationships) has drawn considerable attention and inspired researchers to explore its prevalence in diverse cultures. Accordingly, we examined the direct link between supervisor-subordinate guanxi and employee work behaviors (innovative work behavior and work engagement) by investigating the moderating effect of trust in the supervisor and the mediating effect of psychological empowerment. We collected data randomly from 510 employees (383 subordinates and 127 supervisors) working in China's manufacturing industry. The PROCESS macros operationalize the study constructs to test the presence of moderated mediation. All the hypothesized relationships are supported except the mediating role of psychological empowerment in the supervisor-subordinate guanxi and innovative work behavior relationships. The findings demonstrated that trust in supervisors strengthens the supervisor-subordinate guanxi's direct effect on psychological empowerment and its indirect impact on employees’ work behaviors. To promote positive employees and work behaviors, organizations can develop supervisor-subordinate guanxi that supports organizational goals

Multiple Statistical Analysis Techniques Corroborate Intratumor Heterogeneity in Imaging Mass Spectrometry Datasets of Myxofibrosarcoma

MALDI mass spectrometry can generate profiles that contain hundreds of biomolecular ions directly from tissue. Spatially-correlated analysis, MALDI imaging MS, can simultaneously reveal how each of these biomolecular ions varies in clinical tissue samples. The use of statistical data analysis tools to identify regions containing correlated mass spectrometry profiles is referred to as imaging MS-based molecular histology because of its ability to annotate tissues solely on the basis of the imaging MS data. Several reports have indicated that imaging MS-based molecular histology may be able to complement established histological and histochemical techniques by distinguishing between pathologies with overlapping/identical morphologies and revealing biomolecular intratumor heterogeneity. A data analysis pipeline that identifies regions of imaging MS datasets with correlated mass spectrometry profiles could lead to the development of novel methods for improved diagnosis (differentiating subgroups within distinct histological groups) and annotating the spatio-chemical makeup of tumors. Here it is demonstrated that highlighting the regions within imaging MS datasets whose mass spectrometry profiles were found to be correlated by five independent multivariate methods provides a consistently accurate summary of the spatio-chemical heterogeneity. The corroboration provided by using multiple multivariate methods, efficiently applied in an automated routine, provides assurance that the identified regions are indeed characterized by distinct mass spectrometry profiles, a crucial requirement for its development as a complementary histological tool. When simultaneously applied to imaging MS datasets from multiple patient samples of intermediate-grade myxofibrosarcoma, a heterogeneous soft tissue sarcoma, nodules with mass spectrometry profiles found to be distinct by five different multivariate methods were detected within morphologically identical regions of all patient tissue samples. To aid the further development of imaging MS based molecular histology as a complementary histological tool the Matlab code of the agreement analysis, instructions and a reduced dataset are included as supporting information

The Measurement of Journalistic Role Enactments

Media scholars have primarily assessed journalistic role perceptions through the survey method. We propose conceptual and operational definitions for four role enactments observable through content analysis: dissemination, interpretative, adversarial, and mobilization. We also examined how journalistic role enactments in stories related to organization type (nonprofit and for-profit) and reporter workload. Results show that nonprofit journalists were more likely to include interpretation in stories, whereas for-profit journalists were more likely to enact the dissemination and mobilization roles. In addition, as reporter story number increases, it significantly predicted enacting the dissemination role, while suppressing the interpretative role, and especially the adversarial role enactment
