MATLAB software is used for computer simulation on network evolution process of technology innovation cooperation, and Ucinet characterization analysis software is used to compute characteristic values of simulation network such as power law index of network, average route length and accumulation coefficients. It is compared with the actual network, and the simulation results are analyzed to verify the rationality of the constructed evolution model.展开更多

Maritime cluster's evolution is an under-investigated area, with ramifications in maritime policy and business decision-making. In this paper, we study the evolutionary formation of maritime clusters, in the contemporary European blue economy context. We examine pertinent factors for the sustainable development of maritime clusters, with a strong technical, service and market innovation orientation. We merely examine the significance of legislative, financial, business networking and knowledge management related components. Qualitative empirical testing of the theoretical premises is performed for the Spanish, Italian, Greek and Cypriot cluster entities.展开更多

Attracting theater practitioners and audiences are the main targets. Successful narrator communication is one of the biggest challenges even when theatres facilitate communication with scenery, lighting and costumes etc., as the performance depends primarily on the text and narrator for successful expression. This study views the most important techniques to create a well-made story at both text and performance levels. The researcher begins differentiating storytelling, imitation and characterization, as this understanding assists the objective of this study, which is to determine specific techniques to achieve successful communication with an audience. This research highlights elements which distort story structure; including immersion in narrative without incident description, identified as the most dangerous element due to description being essential to create suspense.1 Text condensation is also crucial. A good writer uses his pen more for deletion than addition. Repeated reading and deletion to condense the story to its optimal is vital. Also included are techniques for good text rhythm in addition to production of captivating beginnings. Further techniques to raise audience attention in text and event building, as well as to determine conflict and types, narrator language use and the structure of the diagnostic viewer, finally, mastering story ending techniques are provided. At performance level, this research provides techniques in creativity prologue, good story rhythm, body language and eye contact together with prop (object) use; all of which enable the narrator to capture and retain audience attention throughout. This research concludes with recommendations on how to achieve a good storytelling performance.展开更多
