    随着时代背景的变迁,新型的领导理论不断应运而生。\"外向型领导\"作为现有领导风格理论的新发展,成为人力资源管理领域中一个值得关注与研究的方向。文章主要采用文献研究方法,通过检索、整理与分析国内外有关\"外向型领导\"的研究文献,梳理了\"外向型领导\"概念的形成过程、内涵、特征与维度;以现有的实证研究为基础,分析了\"外向型领导\"的影响因素;并从概念、维度、影响因素和主要特征四方面对\"外向型领导\"与其他领导风格类型进行了比较,以凸显其概念的独立性;分别从个体层面和组织层面总结了\"外向型领导\"的效能结果及作用机制。在此基础上,构建了\"外向型领导\"未来研究的理论框架。国家自然科学基金面上项目(71672031);;教育部人文社会科学研究规划基金项目(16YJA630018;17YJA630093);;中央高校基本科研业务专项资金资助项目(N160602001);;辽宁省社会科学基金重点项目(L17AGL005);;国家社会科学基金重点项目(16AZD013

    目的:探讨婚姻关系对双方均为唐山地震幸存脊髓损伤(SCI)患者夫妇的生活满意度和心理状况的影响。方法:调查1976年唐山地震幸存SCI患者40名,其中,生活在截瘫康复村已婚者20名(男、女各 10 人),生活在疗养院未婚者 20 名(男、女各10人),比较婚姻状况对两组患者的生活满意度、生活质量、焦虑和抑郁情绪状况的影响。结果:已婚组 SCI患者对目前生活的满意度明显高于未婚组( P 0.05); 焦虑平均得分高于未婚组( P 0.05)。结论:婚姻对提高唐山地震幸存SCI患者的生活满意度和心理健康水平有良好作用

    近年來人機互動模式的多元化發展,提供給使用者許多與以往不同的互動體驗。眼睛是人類接收與傳達資訊的重要感官之一,我們可以藉由觀察眼睛的變化來賦予使用者更貼近其需求的互動方式。本篇論文提出一個可即時偵測並追蹤使用者眼睛特徵點的方法,配合現有的低成本非紅外線視訊攝影機便可準確得到這些特徵點的位置,其中的關鍵技術在於眼睛位於人臉的位置變化差異性不大,因此能透過我們提出基於人臉結構的三階段式偵測法加快搜尋速度並提升穩定性。另一方面,由於系統使用一般的可見光視訊攝影機,不同於紅外光攝影機容易受到環境光的影響,室內、外皆可保有高度的準確性,進而確保此方法在現實生活中的簡易性與可行性。時,為了驗證系統的高效率與準確度,我們提出基於這些特徵點資訊的三種不同類型應用方式:一是計算虹膜中心點與眼角的距離變化判斷眼球的移動方式,配合臉部表情資訊可做為影片自動剪輯的參考依據。二是藉由計算使用者與視訊攝影機之間的相對位置來提供使用者類3D的顯示畫面。三是利用相同資訊藉由校正方法找出使用者注視在螢幕上的位置。The diversification of the development in human-computer interaction provides users more and more interactive experience which is totally different than usual. As one of the sense organs that serve as a proxy for human attention and intention, we can give users better interaction closer to their need by observing the change of the eyes. This paper proposes a low-cost system, using a non-infrared off-the-shelf webcam, which can extract and track the eye features on the face. For getting a real-time and robust result, we propose a three-stage method based on the low variety in the geometry of faces so that these eye features just need to be searched in the small eye rectangle derived from that. Also, our system works without IR lights which are easily affected by environmental ambient light, and it ensures getting high accuracy outdoors as well as indoors and being easy to set up in real life.eanwhile, we propose three different kinds of applications based on our eye feature tracking system in order to validate the efficiency and potentiality. First, we determine the eye movement by calculating the distance between the inner eye corner and the iris center, which will be one of the cues including facial expression for automatic video summarization. Second, we provide a view-dependent display to single user by tracking the relative location between his/her eyes and the camera. Finally, we estimate the point-of-gaze on the screen after calibrating the relation between these features and the sample dots shown on the screen.1 Introduction 1 Related Works 4.1 Active Infrared-Illumination Approaches 5.2 Passive Appearance-Based Approaches 5 Eye Tracking System 10.1 System Architecture 10.2 Face and Eye Detection 11.3 Eye Features Extraction 13.3.1 Eye Corner Location 14.3.2 Iris Circle Location 21.3.3 Blink Detection 24 Evaluation 26.1 Accuracy of Iris Center Location 26.2 Accuracy of Blink Detection 30.3 System Efficiency 32 Applications 33.1 Eye Movement Measurements for Home Video Summarization 33.2 Eye Tracking for View-Dependent Display 36.3 Eye Gaze Estimation 38 Conclusions and Future Works 40.1 Conclusions 40.2 Future Works 41ibliography 4
