AIMS To assess the effect that the duration of face-down posturing has on the outcome of macular hole surgery. METHODS A literature search was conducted to identify studies related to posturing duration following macular hole surgery. Where appropriate, studies were compared in a meta-analysis. The Mantel-Haenszel fixed-effect method was used to calculate the summary statistics. The main outcom...

In this paper, the author extends and further develops research and theory on the relationship between cultural taste and social networks by examining the effects of strength of preference in different cultural domains on the relative closure of personal networks. The results show that as the number of strong preferences held by an individual increases, so do the chances that any two of his or ...

nnovativeness nowledge heterogeneity etwork structure Structural holes theory suggests a variety of possible explanations for the empirically observed relationship between structural holes and individual managerial performance. However, little has been done to disentangle onemechanism fromanother. This paper empirically tests amediatedmoderationmodel that distinguishes between the five differen...

We describe a technique for combined fluid-gas exchange and phacoemulsification 2 weeks after macular hole surgery to achieve rapid visual rehabilitation. The procedure uses a standard cataract set and requires minimal vitreoretinal expertise. We encountered no significant complications and obtained long-term outcomes comparable to those with conventional management.

Through the examination of 11 intact interuniversity research project teams, this study examines the relationship between team leaders, team members, their communication networks (represented as structural holes), and performance. The study shows that in the conduct of their work, the team leaders bridged more structural holes than team members. Although team leaders demonstrated a higher level...

Reaming is a common finishing process for improving the drilled holes surface quality. Choosing an appropriate finishing method in drilling process has a significant effect on the surface quality of holes and in decreasing the process total cost and time. In this study, four similar holes were drilled on the AISI 4340 workpiece with different two pair feed rates. The drilling process was perfor...

In this paper we propose an innovative combination strategy for a system using video and audio stream of a news video to automatically segment it into stories. In our approach, the segmentation is performed in two steps: first, shots are classified by combining three different anchor shot detection algorithms using video information only. Then, the shot classification is improved by using a nov...

We investigate the injection of degenerate Fermi-Dirac electrons into a multimode ballistic conductor under the space-charge-limited regime. The nonequilibrium current fluctuations were found to be suppressed by both Coulomb and Fermi correlations. We show that the Fermi shot-noise-suppression factor is limited below by the value 2kBT/«F , where T is the temperature and «F the Fermi energy of t...

This paper presents our experiments on TRECVID workshop 2008. This year we participated in two challenging tasks, rushes video summarisation and video copy detection tasks. We studied a spatio-temporal video model to represent inter-frame correlation between two streams of video. The rushes summarisation task is aiming at creation of summaries with length not more than 2% of the original video....
