Past studies have shown that Door-in-the-face tactics can induce compliance from negotiators. This research examines the hidden costs of the use of the Door-in-the-face tactic in dyadic negotiations. It shows that learning about opponents’ use of this tactic affects negotiators’ feelings of mistreatment and their behaviours in the subsequent negotiation. It also induces negotiators’ covert, retaliatory behaviour. The results showed that negotiators who had dealt with opponents using the Door-in-the-face tactic made larger demands and attained higher outcomes in the subsequent negotiation. It was also found that feelings of mistreatment by opponents tended to spread over into future negotiations. Feelings of mistreatment mediated the effect of opponents’ use of Doorin-the-face tactics on covert retaliation. Implications of results are discussed and directions for future research are given. © Springer International Publishing Switzerland 2015. Source

Purpose To compare the outcomes of sub-Bowman keratomileusis (100-μm flap) and laser in situ keratomileusis (LASIK) (120-μm flap) using 150-kHz femtosecond laser. Design Randomized, double-masked, contralateral clinical trial. Methods One hundred patients (200 eyes) with myopia or myopic astigmatism were included. Postoperative examinations were performed at week 1 and months 1, 3, 6, and 12. Main outcome measures included postoperative uncorrected (UCVA) and best-corrected distance visual acuity (BCVA); manifest refraction spherical equivalent; efficacy and safety indices; corneal thickness; and complications. Results The mean age of patients was 33.9 ± 7.9 years. Overall, the preoperative UCVA, BCVA, and manifest refraction spherical equivalent were 1.349 ± 0.332, -0.022 ± 0.033, and -5.81 ± 1.61 diopters, respectively. No significant difference was observed in preoperative (P ≥.226) or intraoperative parameters (P ≥.452) between both groups, except residual stromal thickness (P <.001). The UCVA, manifest refraction spherical equivalent, and central corneal thickness stabilized by 1 week, while the thinnest corneal thickness stabilized by 3 months postoperatively. There was no significant difference between both groups for any parameter during all follow-up visits (P ≥.132) except the 3-month safety index, which was better in the sub-Bowman keratomileusis group (P =.007). Soft opaque bubble layer was noted intraoperatively in 12 cases (7, 100-μm group; 5, 120-μm group; P =.577). No postoperative complications were observed. Conclusions Our study did not find any differences in the visual and refractive outcomes between femtosecond-assisted sub-Bowman keratomileusis and LASIK. Both surgeries resulted in quick visual recovery as early as 1 week postoperatively. © 2015 by Elsevier Inc. All rights reserved. Source

This paper presents a multiphase fuzzy region competition model that takes into account spatial and frequency information for image segmentation. In the proposed energy functional, each region is represented by a fuzzy membership function and a data fidelity term that measures the conformity of spatial and frequency data within each region to (generalized) Gaussian densities whose parameters are determined jointly with the segmentation process. Compared with the classical region competition model, our approach gives soft segmentation results via the fuzzy membership functions, and moreover, the use of frequency data provides additional region information that can improve the overall segmentation result. To efficiently solve the minimization of the energy functional, we adopt an alternate minimization procedure and make use of Chambolle's fast duality projection algorithm. We apply the proposed method to synthetic and natural textures as well as real-world natural images. Experimental results show that our proposed method has very promising segmentation performance compared with the current state-of-the-art approaches. © 2010 IEEE. Source

Coaching is commonly defined as a developmental practice which requires the coach to provide an informal, on-going form of goal-focused development aimed at improving and enhancing a person's performance. However, most of the previous human resource development studies examined coaching in face-to-face communication (FtFC), but fewer studies have looked at coaching in computer-mediated communication (CMC). This paper will focus on this untested concern which is how leaders appropriate the CMC to effectively coach their followers and thus regulate behavior and improve performance. More specifically, I examined the impacts of the leaders' coaching behaviors on their choice of media of coaching, thus influencing follower's work-related performances. Theoretical and managerial implications were discussed. © 2015 IEEE. Source

Despite the increasing popularity of peer feedback in EFL writing classrooms, little research has been conducted to explore how individual factors such as learner beliefs may influence L2 students’ use of peer feedback. From an ecological perspective (van Lier, 2000, 2004), this exploratory case study investigated the extent of peer feedback use by two purposefully-chosen Chinese EFL university students and how their use of feedback was mediated by learner beliefs, a salient factor that emerged from the study. Detailed qualitative data were collected from multiple sources: written documents, stimulated recall, semi-structured interviews, and classroom observations. The findings indicated that the two students integrated peer comments selectively into their revision across two tasks. The selective use of peer feedback was found to be mediated by writing beliefs related to qualities of good English expository writing, to the importance of word limit and to student reviewer roles. Seen from an ecological perspective (van Lier, 2000, 2004), these writing beliefs were employed by the students to create affordances to mediate the use of feedback while some of these beliefs were shaped by local classroom affordances (Peng, 2011). Pedagogical implications of the findings are also discussed. © 2016, Australian International Academic Centre PTY LTD. All rights reserved. Source
