There has been growing interest in the relationship between HRM practices and organizational performance, but few studies have provided evidence supporting this relationship by considering the moderating effect of CEO support. Therefore, this study intends to examine the effects of various HRM practices on organizational performance and the moderating effect of CEO support on the relationship between HRM practices and organizational performance through a survey on 215 Chinese firms. The results indicate a positive relationship between HRM practices and organizational performance and verify the moderating effect of CEO support on this relationship. This study is the first one on demonstrating the moderating effect of CEO support on the relationship between HRM practices and organizational performance in the context of Chinese firms. These findings may help adding knowledge to the Chinese firms' CEOs while considering about making HR policies and HRM activities which are mainly decided by their attitudes and participations.
We conducted a survey with 744 highly skilled full-time employees of South Korean We conducted a survey with 744 highly skilled full-time employees of South Korean organizations to examine the associations among 2 organizational factors, namely organizations to examine the associations among 2 organizational factors, namely centralization and communication opportunities, and 2 distinct forms of employee silence, centralization and communication opportunities, and 2 distinct forms of employee silence, namely acquiescent and prosocial silence. Confirmatory factor analysis and structural namely acquiescent and prosocial silence. Confirmatory factor analysis and structural equation modeling were performed to test our hypothesized model. The findings revealed that equation modeling were performed to test our hypothesized model. The findings revealed that centralization positively influenced employees' acquiescent silence and that communication centralization positively influenced employees' acquiescent silence and that communication opportunities positively impacted their prosocial silence. Theoretical and practical opportunities positively impacted their prosocial silence. Theoretical and practical implications, limitations, and future research directions are discussed. implications, limitations, and future research directions are discussed.
Neurological deficits after brain surgery are not uncommon, and correct and prompt differential diagnosis is essential to initiate appropriate treatment. We describe a patient suffering from loss of consciousness due to hyperammonemia, following valproic acid treatment after surgery for an unruptured cerebral aneurysm. A 57-year-old female patient underwent successful aneurysmal neck clipping to correct an unruptured aneurysm. Her postoperative course was good, and she received anti-epileptic therapy (valproic acid) and a soft diet. Within a few days the patient experienced mental deterioration. Her serum valproic acid reached toxic levels (149.40 mg/L), and serum ammonia was fifteen times the upper normal limit (553 mmol/L; normal range, 9-33 mmol/L). After discontinuation of valproic acid and with conservative treatment, the patient recovered without any complications. Valproate-induced hyperammonemic encephalopathy is an unusual but serious neurosurgical complication, and should not be disregarded as a possible cause of neurological deficits after neurovascular surgery. Early diagnosis is crucial, as discontinuation of valproic acid therapy can prevent serious complications, including death.
We conducted a survey to verify the relationship between vertical and horizontal collectivism and Chinese organizational citizenship behavior (Chinese OCB) with a focus on the moderating effects of guanxi. Data were collected through emails and an online survey from 432 full-time Chinese
employees. The findings of the study indicated that collective orientation was positively related to Chinese OCB, and that guanxi moderated only the relationship between vertical collectivism and Chinese OCB. Our findings help strengthen the understanding of the dimensions of Chinese OCB.
Theoretical contributions are discussed; in particular, possible reasons for the nonsignificant moderating effects of guanxi on horizontal collectivism and Chinese OCB are given. Study results provide not only practical implications for existing employers or human resource managers, but also
for start-up entrepreneurs in their human resource management practices and innovative policies. Limitations of the study are pointed out and topics for future research are suggested.
This study has analyzed how the network structure (density, centrality) affects the performance (convergence, overall) in Small and Medium-Sized Enterprises (SMEs) with the different business exchange activities. In addition, we conducted a moderating effect of absorptive capacity (ability, motivation). Based on previous literature about the network and absorptive capacity, research hypotheses were developed and tested using a sample of 226 SMEs in South Korea. The results show that network density and centrality have a positive effect on perceived convergence and overall performance. These results are consistent with previous network studies relating to structural characteristics. To raise total performances in firms with different business exchange activities, they need to enhance density and centrality. For example, firms with different business exchange activities and high levels of density and centrality are able to easily obtain various types of information from other members of 7000 firms in Korea. Through this, they can improve performance. We also conducted the moderated regression analysis. The results show that employee ability has a positive moderating effect on the relationship between centrality and the overall performance while employee motivation has a negative moderating effect. The implications and directions for future study along with limitations are presented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
