Building mega data center from heterogeneous containers
No full textData center containers are regarded as the basic units to build mega data centers. In practice, heterogeneity exists among data center containers, because of technical innovation and vendor diversity. In this paper, we propose uFix, a scalable, flexible and modularized network architecture to interconnect heterogeneous data center containers. The inter-container connection rule in uFix is designed in such a way that it can flexibly scale to a huge number of servers with stable server/switch hardware settings. uFix allows modularized and fault-tolerant routing by completely decoupling inter-container routing from intra-container routing. We implement a software-based uFix stack on the Linux platform. Simulation and experiment results show that uFix enjoys high network capacity, gracefully handles server/switch failures, and brings light-weight CPU overhead onto data center servers

Does the size of the femoral head correlate with the incidence of avascular necrosis of the proximal femoral epiphysis in children with developmental dysplasia of the hip treated by closed reduction?
No full textPurpose The purpose of this study was to identify if any correlation between size of the proximal femoral epiphysis and avascular necrosis (AVN) exists. Methods We retrospectively reviewed 111 patients with developmental dysplasia of the hip treated by closed reduction (124 hips). The diameter and height of both femoral head and ossific nucleus were assessed on preoperative MRI. Results The diameter and the height of the femoral head as well as of the ossific nucleus of the contralateral side were significantly greater than the dislocated side. AVN occurred in 21 (16.9%) out of 124 hips. The rate of AVN gradually decreased with age: 30.0% at six to 12 months, 18.2% at 12 to 18 months and 3.7% at 18 to 24 months. Spearman correlation analysis showed that age is negatively correlated with the incidence of AVN (r =-0.274; p = 0.002) and the diameter of the femoral head has a significantly negative association with the incidence of AVN (r =-0.287; p = 0.001). No significant association was observed between the incidence of AVN and height of the femoral head or size of the ossific nucleus. Hips with AVN were significantly smaller than hips without AVN. Conclusions The size of both the femoral head and the ossific nucleus increase with age although the dislocated femoral head is smaller compared with the contralateral side. The diameter of the femoral head and not the size of the ossific nucleus negatively correlate with the risk of AVN, with a bigger femoral head showing lower risk of AVN
Does the vascular development of the femoral head correlate with the incidence of avascular necrosis of the proximal femoral epiphysis in children with developmental dysplasia of the hip treated by closed reduction?
No full textPurpose: The purpose of this study was to identify the correlation between the vascular development of the femoral head and avascular necrosis (AVN) in patients with developmental dysplasia of the hip (DDH) treated by closed reduction (CR). Methods: We retrospectively reviewed 78 patients with DDH treated by CR (83 hips). The vascular maturity, number of vessels and perfusion changes of the femoral head were assessed on perfusion MRI (pMRI) before and after CR. Results: The number of vessels (mean 4.2 sd 1.4) of the femoral head and the ratio (36.1%) of mature vessels (type III) on the dislocated side were significantly less than those at contralateral side (mean 6.0 sd 1.2; 82.2%) (p < 0.001). Of the included 83 hips, 39 hips (61.5%) showed decreased perfusion of the femoral head, including partial decreased (Class B, 47.0%) and global decreased (Class C, 14.5%), at the dislocated side, which was significantly more than those at contralateral side (0.0%) (p < 0.001). In total, 32 out of 83 hips (38.5%) developed AVN. The rate of AVN with Class A (18.8%) which perfusion of the femoral head was normal Conclusion: The vascular development and perfusion changes of the femoral head on the dislocated side are significantly worse than those at contralateral side. Immature vascularity of the femoral head before CR and poor perfusion of the femoral head after CR may be risk factors for AVN in patients with DDH
"Workplace Social Support, Adjustment, and Motivation of Chinese Rural Migrant Workers"
No full textUsing data drawn from a cross-organizational sample of 632 Chinese rural migrant workers (CRMWs), the authors examine the relationships between workplace social support and two common measures of worker motivation: turnover intention and work engagement. Taking a context-sensitive approach the authors identify three sources of workplace social support for CRMWs: Laoxiang (native-place fellows) coworkers, local coworkers, and supervisors. Further, drawing on social psychological perspectives the authors propose adjustment, a variable that crosses work and life domains, as a new mechanism through which workplace social support links with worker motivation. Finally, by viewing workplace social support as social capital and applying social network analysis to the institutional and cultural context surrounding CRMWs, the authors hypothesize on the relative importance of different sources of workplace social support to CRMWs’ motivation (in descending order): Laoxiang coworkers, supervisors, and local coworkers. Results of multilevel analysis largely support these hypotheses. The authors discuss theoretical and practical implications of these findings and suggest directions for future research
Third-party reactions to supervisory mistreatment: a multilevel moderated mediation model
No full textIntegrating a relational perspective with recent theoretical development on third parties’ moral emotions, we developed a multilevel moderated mediation model that explained why and how third parties reacted to supervisory mistreatment of their coworkers and what factor at the supervisor-level moderated their different reactions. We tested this model with three-wave survey data collected from a sample of 882 team members and 109 team leaders. The results showed that third parties, who received favorable treatments from the exchange relationship with victimized coworkers, would feel morally guilty for supervisory mistreatment of their coworkers. To alleviate guilt, third parties would react to both the victim and perpetrator. In addition, supervisor’s power distance orientation had opposing cross-level moderation effects, which strengthened the positive influence of moral guilt on victim-target reaction (i.e., coworker aid), whereas weakened the positive effect of moral guilt on perpetrator-target reaction (i.e., report mistreatment to a higher-level authority). Both theoretical and practical implications were discussed
