Facing contradictory emotions in event marketing: leveraging on surprise Michela Addis University of Rome 3, Rome, Italy Giulia Miniero Universita della Svizzera Italiana, Lugano, Switzerland and SDA Bocconi Scuola di Direzione Aziendale, Milano, Italy, and Isabella Soscia SKEMA Business School, Sophia Antipolis, France Abstract Purpose – This paper aims to explore the role of surprise in reducing the negative impact of an undesired emotion, such as embarrassment, on the attitudes and behavioral intentions of consumers taking part in an event. Design/methodology/approach – In total, 220 consumers took part in a pre-test/post-test quasi-experimental within-subject design. Data were analyzed using structural equation modeling. Findings – Findings show that an in-store social event designed to elicit young customersrsquo; surprise and feeli

1.6 DESIGN CODES AND SPECIFICATIONS The design of concrete structures such as those of Figsa1.1 to 1.12 is generally done within the framework of codes giving specific requirements for materials, structural analysis, member proportioning, etc. The International Building Code (Ref.1.2) is an example of a consensus code governing structural design and is often adopted by local municipalities. The responsibility of preparing material-specific portions of the codes rests with various professional groups, trade associations, and technical institutes. In contrast with many other industrialized nations, the United States does not have an official, government-sanctioned, national code. The American Concrete Institute (ACI) has long been a leader in such efforts. As one part of its activity, the American Concrete Institute has published the widely recognized Building Code Requirements for Structural Concrete (Ref.1.10), which serves as a guide in the design and construction of reinf

3.6.PRACTICAL CONSIDERATIONS INTHE DESIGN OF BEAMS To focus attention initially on the basic aspect of flexural design,the preceding examples were carried out with only minimum regard for certain practical considerations that always influence the actual design of beams.These relate to optimal concrete proportions for beams,rounding of dimensions,standardization of dimension,required cover for main and auxiliary reinforcement,and selection of bar combination.Good judgment on the design engineer is particularly important in translating from theoretical requirement to practical design.Several of the more important aspects are discussed here;much additional guidance is provided by the publications of ACI(Refs.3.7and3.8)and CRSI(Refs.3.9to3.11) Concrete Protection for Reinforcement To provide the steel with adequate concrete protection against fire and corrosion ,the designer must maintain a certain minimum thickness of concrete cover outside of the outermost steel.The

El-Naggar 开罗大学工程学院工程数学与物理系，埃及吉萨12613 摘要 本文从理论上研究了一维含负材料的一维柱状光子晶体（1DCPC）中传播的电磁波。我们研究了三个间隙的光学性质，即零有效相位（零-0）、零介电常数（零ε）和零可操作性（零mu;）。我们计算横向电（磁）TE（TM）偏振的光学反射率。在圆柱坐标系中采用传递矩阵法。我们研究方位角的影响。模式数（m）和这些间隙上的起始半径。结果表明，在mu;（ε）为M 1符号的频率下，Te（TM）极化的零mu;（零ε）间隙出现。间隙宽度通过减小起始半径或增加m来增加，而零-pi;间隙保持不变。此外，我们还提出了一种简单设计的1DCPC，它具有偏振无关的宽间隙，特别是对于高方位模式数（M＞2）。我们的结
