Analysis of structural behavior during collision event accounting for bow and side structure interaction

The main goal of this study was to investigate the effects of selected ship collision parameter values on the characteristics of the absorbed energy in several ship collision scenarios. Non-linear simulations were performed using a finite element method （FEM） to obtain virtual experiment data. In the present research, the size of the side damage from a collision phenomenon were measured and used to verify the numerical configuration together with the calculation results using an empirical equation. Parameters in the external dynamics of a ship collision such as the location of the contact point and velocity of the striking ship were taken into consideration. The internal energy and deformation size on the side structure were discussed further in a comparative study. The effects of the selected parameters on several structural behaviors, namely energy, force, and damage extent were also observed and evaluated in this section. Stiffener on side hull was found to contribute significantly into resistance capability of the target ship against penetration of the striking bow. Remarkable force during penetration was observed to occur when inner shell was crushed as certain velocity was applied in the striking bow.

符号互动:品牌数字传播的社会认同建构

网络化个体主义是推动品牌社会认同加速离散的重要力量,由此造成品牌社会认同的危机,然而,网络个体的重新聚集也成为品牌构建新社会认同的契机。因此,探索全新的品牌数字传播对社会认同的建构理路,对于理解广告品牌研究的理论与实践具有重要意义。研究基于符号互动理论,对“后浪现象”这一数字传播典型案例进行探讨,从个体、群际和社会三重互动情境着手分析,提炼出品牌数字传播构建社会认同的两个关键环节:“情感化的符号生产”与“仪式化的公众文本创作”。在个体间情感认同形成层面,符号的生产促成情感心理空间的连接和扩大,其是形成情感认同的中间纽带;在群际间层面,人们通过互动仪式链参与公众文本创作,促进群际间的意义生产,突破圈层的意义边界,助力群际间认同。

形象建构、理性选择与利弊相权:符号互动论视域下青年MBTI求偶行为研究

青年群体使用MBTI求偶已然成为一种时尚。这一问题关涉青年婚恋观念、社会交往、生育意愿等问题。从符号互动论视域出发探究青年使用MBTI求偶的行为发现,在求偶前期,青年群体运用MBTI建构起理想的自我形象和他者形象,缩小了主体间的“社会距离”。求偶过程中,他们充分发挥MBTI的“社交货币”效益,通过工具理性优化求偶路径。求偶的“社会互动”结果呈现两种分野。这种方式有助于提高求偶成功的概率,加深对自我的认知;但是对MBTI的不当使用和过分依赖会使主体陷入主体物化和标签困境的泥淖。
