Product advertisement mostly benefits from the audiovisual commercials and advertisements on mass media （television, radio, newspaper, magazine, poster, brochure, Internet etc.）. Today, TV, radio and Intemet are considered to have great importance among the most widely used means of mass media. Initial advertisement for each product plays a significant role in getting a bigger market share for that product. Thus, manufacturing companies need brands, taglines, catchphrases and jingles for their commercials broadcasted on mass media. Astonishing words or expressions which catch the consumers＇ attention play a highly significant role in commercials. Slogans which are created sometimes using melodious or rhythmical expressions, and imperatives, or sometimes slang and daily language support convincing power of the commercials. The mentioned slogans are indeed examples of creativeness. This study primarily includes the commercials, ways to produce slogans and their characteristics, together with identifying the slogans in the commercials broadcasted in Turkey and Russia, created by using language games, which include brand names. Then, aforementioned slogans will be reviewed with regards to artistic stylistics, a sub branch of functional stylistics. Finally, similar and different aspects of the language games in Turkish and Russian commercials will be compared based on the findings obtained from the analyses.展开更多

Within marketing research, objective assessment of TV commercials is performed by use of Eye-Tracking devices. Brain research has been dominated by NMRI technologies during the last years. However, information content and time resolution are much better when monitoring electric activity by spectral analysis. The current experimental approach was initiated in order to test the combination of a newly developed EEG technology (Neurocode-Tracking) with commercially available Eye-Tracking. Ten male subjects were exposed to a reference recording condition (watching a fixed cross on the screen) followed by 5 TV commercials representing 5 different banks. Video films obtained from Eye-Tracking (so-called heat maps) were synchronized with the results of Neurocode-Tracking in form of a second video with a time resolution of 364 ms per image. Spectral power analysis of the EEG in different brain regions allowed for assessment of single scenes for cognitive and emotional responses. Averaging of data over the whole time course gave information on mental activation, attention, visual perception, memory, pleasure and tension. Comparison of the 5 commercials to reference recording revealed the clip of the Targo-Bank having the highest values with respect to mental activation and attention.These experiments have proven that the combination of Neurocode-Tracking with Eye-Tracking can be successfully used in advertisement research and gives valid information on individual as well as group dependent cognitive and emotional responses leading to objective assessment of TV commercials.展开更多

文摘The term “neuromarketing” suggests a combination of marketing research and brain research. Within marketing research, objective assessment of TV commercials is performed by use of Eye-Tracking devices. Brain research has been dominated by NMRI technologies during the last years.

The current experimental approach was initiated in order to test the combination of a newly developed EEG technology (Neurocode-Tracking) with commercially available Eye-Tracking.

文摘Circulose,a global leader in recycled pulp production,hasreached a strategic partnership agreement with Tangshan SanyouChemical Fiber,a front-runner in the cellulose fiber industry.Thiscollaboration marks a significant milestone in the commercializa-tion and scaling of CIRCULOSER,whle also propelling TangshanSanyou's brand toward greater international recognition.
文摘At the 20th China-ASEAN Expo(CAEXPO)in 2023,Bruneibased airline startup GallopAir signed a letter of intent(LOI)with the Commercial Aircraft Corporation of China(COMAC)for the purchase of 30 aircraft,including the C919 jet airliner and the ARJ21(now known as C909)regional jet.
文摘Fischer-Tropsch synthesis(FTS)and hydroformylation are pivotal chemical processes for converting syngas and olefins into valuable hydrocarbons and chemicals.Recent advancements in catalyst design,reaction mechanisms,and process optimization have significantly improved the efficiency,selectivity,and sustainability of these processes.This Account introduces the relevant research activities in the Research Center for Catalysis in Syngas Conversion and Fine Chemicals(DNL0805)of Dalian Institute of Chemical Physics(DICP),Chinese Academy of Sciences.The reactions of interests include FTS,heterogeneous hydroformylation of olefins,alcohol dehydration and oxidation,andα-olefin polymerization,with the emphasis on developing innovative catalysts and processes to address the challenges of traditional processes.Exemplified by the discovery of robust Co-Co_(2)C/AC for FTS and Rh_(1)/POPs-PPh_(3) for heterogeneous hydroformylation of olefins,it demonstrates how lab-scale fundamental understandings on the active sites of catalysts leads to pilot-plant scale-up and finally commercial technologies.Perspectives on the challenges and directions for future developments in these exciting fields are provided.
