Prior studies have focused primarily on the issue of consumers’ privacy concerns in personalized advertising, but little is known about the effect of transparency awareness using data collection notifications on consumers. This study focuses on the relationship between consumers’ perceptions of the AI algorithms underlying online behavioral advertising (OBA) and the advertising effects. Our research model indicates that displaying data collection notifications regarding OBA and personalized ads increases favorable perceptions of AI systems, such as transparency. Moreover, the model suggests that personalized ads induce higher perceived surveillance than non-personalized ads.

Laser scabbling has the potential to be a valuable technique capable of effectively decontaminating highly radioactive concrete surface at nuclear decommissioning sites. Laser scabbling tool using an optical fiber has a merits of remote operation at a long range, which provides further safety for workers at nuclear decommissioning sites. Furthermore, there is no reaction force and low secondary waste generation, which reduces waste disposal costs. In this study, an integrated decontamination system with laser scabbling tool was employed to test the removal performance of the concrete surface. The integrated decontamination system consisted of a fiber laser, remote controllable mobile cart, and a debris collector device. The mobile cart controlled the translation speed and position of the optical head coupled with 20 m long process fiber. A 5 kW high-powered laser beam emitted from the optical head impacted the concrete block with dimensions of 300 mm × 300 mm × 80 mm to induce explosive spalling on its surface. The concrete debris generated from the spalling process were collected along the flexible tube connected with collector device. We used a three-dimensional scanner device to measure the removed volume and depth profile.

Laser scabbling experiments were conducted with the aim of developing concrete decontamination technology. Laser scabbling system contains a 6 kW fiber laser (IPG YLS-6000, λ=1,070 nm) and optical head, which are connected with process fiber (core dia.: 600 μm, length: 20 m). Optical head consists of two lenses (f = 160 mm and 100 mm) to collimate and focus laser beam. The focused laser beam is passed through the small diameter of nozzle (throat dia.: 3 mm) to prevent the laser-produced debris into head. And then, the focused beam is directed toward concrete block as continuously diverging. The diverged laser beam was incident on the high-strength concrete with 300 mm (length) × 300 mm (height) × 80 mm (width) to induce explosive spalling on the concrete surface. The optical head was moved by X-Y-Z manipulate coupled with a computerized numerical control while scabbling. We have observed not only active spalling on the concrete surface but energetic scattering of laserproduced debris when scabbling on high-strength concretes. It indicates the need for a device capable of collecting the laser-produced debris. We newly designed and manufactured dust collector coupled with cylindrical tube to prevent scattering of laser-produced debris into ambient environment. The collecting system was evaluated by estimating the collecting efficiency for laser-produced debris while scabbling. The collecting efficiency was calculated on the basis of the information on the mass loss of concrete block after laser scabbling and the mass of collected debris in a container. The collecting efficiency was found to be over 85%.

A laser scabbling experiment was performed using a high-power fiber laser to investigate the removal rate of the concrete block and the scabbled depth. Concrete specimens with a 28-day compressive strength of 30 MPa were used in this study. Initially, we conducted the scabbling experiment under a stationary laser beam condition to determine the optimum scan speed. The laser interaction time with the concrete surface varied between 3 s and 40 s. The degree of spalling and vitrification on the surface was primarily dependent on the laser interaction time and beam power. Furthermore, thermal images were captured to investigate the spatial and temporal distribution of temperature during the scabbling process. Based on the experimental results, the scan speed at which the optical head moved over the concrete was set to be 300 mm∙min−1 or 600 mm∙min−1 for the 4.8-kW or 6.8-kW laser beam, respectively. The spalling rates and average depth on the concrete blocks were measured to be 87 cm3∙min−1 or 227 cm3∙min−1 and 6.9 mm or 9.8 mm with the 4.8-kW or 6.8-kW laser beams, respectively.

Introduction The article presents a technique for studying the perception of images of animated characters based on the application of psychophysiological methods of recording data in combination with classical sociological methods. The theoretical justification of the EEG, GSR, PPG and video-oculography methods application in testing affective stimuli is provided. The applications of the technique at various stages of creating animated characters are presented. The main advantages of the technique are noted: the ability to work with a target audience starting from the age of 3 years old and the recording of physiological data directly while viewing a stimulus material. One of the most topical objectives for the authors of animation films is the creation of animated characters, which elicits viewers’ sympathy, influences general perception of the movie and affects its distribution and final box office. The methodology that allows to study a perception of characters at different stages of its creation, from conception to final embodiment, will help authors to make changes and adjustments before moving to another technological stage, which will reduce production costs and more accurately meet the needs of the audience. The advantage of the proposed methodology on the one hand, is the efficiency of working with child audience, which is the most difficult in terms of obtaining valid information. On the other hand, it is the possibility of obtaining data directly during the perception of stimuli, which is impossible while using sociological methods. Theoretical development The EEG method is an integral component of classical neuromarketing studies of perception of audiovisual materials, allowing assessing the attractiveness and motivational component in the choice situation. A significant number of scientific publications demonstrate the correlation between the arousal of positive emotions and the activation of the left hemisphere. This is determined by the lower power of the alpha rhythm in the left frontal lobe as compared to the right one. While a person experiences negative emotion, the right frontal lobe is more active, thus, the alpha rhythm power is lower there (Rusalov, 1988, 1999; Aftanas, 2000; Vecchiato, et al. 2011; Ravaja, 2013, Harmon-Jones, et al. 2009). In our methodology the stimuli attractiveness index is calculated based on the EEG data. The high index scores are associated with positive emotions and the interest to object; low scores are associated with negative feelings and indifference. Changes in the indicators of the vegetative nervous system activity are strongly connected to an emotional manifestation; these changes are caused by anatomical and physiological conditions. Numerous studies have demonstrated that a decrease in the amplitude of the plethysmogram is observed when a person experiences negative emotions. On the contrary, an increase in the amplitude is observed during positive emotions experience (Sylvia, et al, 2008; Kreibig, et al., 2007). The emotional involvement indicator refers to the power of emotional inclusion when viewing a character. It is calculated by the registration of vegetative indices related to emotions (EDA, plethysmogram, breathing). Interest is a cognitive need to learn about what is happening on the screen; it reflects the direct interest in visual information. The understanding of interest is mostly based on the psychological researches (Izard, 1999; Silvia, 2006), however, the intensity of the parameter can correlate with objective physiological indicators based on oculomotor activity. The process of the characters’ image scanning is accompanied by the distribution of attention to individual areas of interest (Jenkin, 2001). In this methodology we allocated the areas of interest according to a different character or a separate element of the visual image of the hero. Research design The method is based on a complex approach combining neurophysiological methods of recording physiological reactions while the demonstration of animated characters’ images in combination with sociological research methods used after the stimuli demonstration. The developed technique allows the use of any audiovisual materials created at different stages of work on a character as stimuli (design of character, design of character accessories, character model in static in 2D or 3D, technological test from 10 to 30 seconds). The data was recorded via the high-speed remote binocular eye-tracking system RED250, the professional computer polygraph (PCP) “Energia” and the electroencephalograph B-AlertX24. Result and conclusion 20 images of animated movie characters were tested on 150 respondents during the research (a child audience of animated films and an adult audience with children aged 3-8 years, who make the decision to choose an animated film). A restriction for the EEG method has been found in working with children under 7 years old. At this age the analyzed rhythms are slowed down and not completely formed. The analysis of this group of respondents was focused on vegetative indices. The predicting method of perception of animated characters’ images allows us to define the evaluation parameters of the image of the animated character in terms of attractiveness, emotional involvement and interest. The methodology will be further developed and will include a differential analysis of emotional reactions by virtue of the electroencephalography method in response to the presentation of characters or video samples. The commercial use of the technique is planned for the purpose of testing characters at all stages of animation film production.

Western social media platforms like Facebook, YouTube, etc are banned in China. In their places, Weibo, WeChat, Youku and more are the main social media channels in China and thus the main battlefields of social marketing for brands entering China Market. WeChat is the largest social network in China, with over 900 million users daily, for nearly all types of services, including booking flights, restaurant table reservation, shopping, paying bills, etc. To cater the needs of the new generation of Chinese digital natives, a mobile app eM++ was developed that creates new customer services and enables tailored fashion marketing. This new mobile app eM++ works well in China, will this be also well received in other countries? This research investigates consumers’ perception of this new fashion e-tailoring e-shopping concept in UK. Will this type of e-tailored services be welcome in UK? Will consumers welcome this type of e-shopping service in UK? Or they prefer the traditional way of tailoring and shopping? Which social media platforms should be used for promotion? The sample population of this research covers both male and females from China and UK aged 18 years old or above with experience of searching and/or buying clothing items online. Convenient sampling and snow-balling sampling methods are used. In UK, recruitment of volunteers for this project will be via emails to colleagues and previous students, as well as via posters of recruiting volunteers for this project posted on campus. Details of the project and experiment will be included in both emails and posters. Volunteered participants are asked to answer a pre-experiment online questionnaire. Based on their answers, suitable participants will be invited to participate the experimental part (which is trying a fashion app and then answer the post-experiment questionnaire). Participants successfully completed the experiment and post-experiment questionnaire will be given their own body measurements with a 3D model in user’s customised shape, as well as a discount coupon for future use when the app is officially launched. This research will have mainly quantitative data analysis, SPSS will be used to analyse the data. There will have a few open-ended questions that qualitative data analysis method will be employed. This research will explore the feasibility of this service in UK and formulate a cross-cultural comparison between China and UK.

Digital technological development has created different new possibilities. New products and services are developed to cater the needs and wants of these digital consumers (or digital natives). It has also changed the means of marketing communications. Social media has become an integral part of many people’s lives, thus social media marketing is found in the marketing strategy of every brand. Western social media platforms like Facebook, YouTube, Twitter and so on are banned in China. In their places, Weibo, WeChat, Youku and more are the main social media channels in China and thus the main battlefields of social marketing for brands entering China Market. WeChat is the largest social network in China, with over 900 million users daily. Chinese users spend an average of over 70 minutes a day using WeChat, for nearly all types of services, including booking flights, restaurant table reservation, shopping, paying bills, hailing taxi, transferring money, and posting Moments on their walls, etc. Not only that, WeChat allows companies and celebrities to create official accounts to generate content for promotional purposes. Moreover, WeChat allows one-to-one personalized interaction between brands and the users. To cater the needs of the new generation of Chinese digital natives, a mobile app eM++ was developed that creates new customer services and enables tailored fashion marketing. The eM++ app has three components. The first core component is 1Measure, which users can obtain their body measurements by skimpily taking two photographs of themselves in normal clothing anywhere and anytime. Without the involvement of expensive equipment, users can enjoy similar benefit of body scanning but more flexibility and convenience, they not only instantly receive their measurements but also have their digital body model and a shape analysis report. Based on this information, the second component of the app eShop allow users to shop fashion items currently available in different online fashion stores like ASOS, Zara, and H & M, etc. In eShop, users are suggested the right sizes to order for different fashion items, based on their measurements and shape information, and also mix-and-match recommendations. The last component is eTailor, where users can order clothing like suit jackets, pants and shirts that tailored made for them, but save the need to take body measurements in a physical store. This new digital service will first be launched in China as there is high demand on Made-to-Measure fashion and marketing through WeChat social media platform. This paper will discuss how to market this new digital service using social media like WeChat in China and consumers’ reactions to this new business model in this digital world.

We investigate two abnormal CME-Storm pairs that occurred on 2014 September 10 - 12 and 2015 March 15 - 17, respectively. The first one was a moderate geomagnetic storm (Dstmin  -75 nT) driven by the X1.6 high speed flare-associated CME (1267 km s−1) in AR 12158 (N14E02) near solar disk center. The other was a very intense geomagnetic storm (Dstmin  -223 nT) caused by a CME with moderate speed (719 km s−1) and associated with a filament eruption accompanied by a weak flare (C9.1) in AR 12297 (S17W38). Both CMEs have large direction parameters facing the Earth and southward magnetic field orientation in their solar source region. In this study, we inspect the structure of Interplanetary Flux Ropes (IFRs) at the Earth estimated by using the torus fitting technique assuming self-similar expansion. As results, we find that the moderate storm on 2014 September 12 was caused by small-scale southward magnetic fields in the sheath region ahead of the IFR. The Earth traversed the portion of the IFR where only the northward fields are observed. Meanwhile, in case of the 2015 March 17 storm, our IFR analysis revealed that the Earth passed the very portion where only the southward magnetic fields are observed throughout the passage. The resultant southward magnetic field with long- duration is the main cause of the intense storm. We suggest that 3D magnetic field geometry of an IFR at the IFR-Earth encounter is important and the strength of a geomagnetic storm is strongly affected by the relative location of the Earth with respect to the IFR structure.

We conducted an unbiased near- to mid-infrared imaging and spectroscopic survey of the Large Magellanic Cloud (LMC) as a part of the AKARI Mission Program \Large-area Survey of the LMC" (LSLMC, PI: T. Onaka). An area of about 10 square degrees of the LMC was observed by ve photometric bands (3.2, 7, 11, 15, and 24 m) and a low-resolution slitless prism (2 { 5 m, R 20) equipped with AKARI/IRC. We constructed and publicly released photometric and spectroscopic catalogues of point sources in the LMC based on the survey data. The catalogues provide a large number of near-infrared spectral data, coupled with complementary broadband photometric data. Combined use of the present AKARI LSLMC catalogues with other infrared point source catalogues of the LMC possesses scientic potential that can be applied to various astronomical studies.

We have been performing daily VLBI monitoring of the ux density of Sagittarius (Sgr) A* at 22 GHz from February 2013 to August 2014 using a sub-array of the Japanese VLBI Network (JVN). The purpose of this monitoring is to explore the ux density variability at daily time resolution for a period longer than one year with the G2 cloud approaching. The ux density of Sgr A* is basically stable during the observational period, though there are some small variations. The average and scattering range are consistent with the previously observed values. We have observed no strong are of Sgr A* although it is near the expected peri-center passing.

Polarbear is a ground-based experiment located in the Atacama desert of northern Chile. The experiment is designed to measure the Cosmic Microwave Background B-mode polarization at several arcminute resolution. The CMB B-mode polarization on degree angular scales is a unique signature of primordial gravitational waves from cosmic in ation and B-mode signal on sub-degree scales is induced by the gravitational lensing from large-scale structure. Science observations began in early 2012 with an array of 1,274 polarization sensitive antenna-couple Transition Edge Sensor (TES) bolometers at 150 GHz. We published the first CMB-only measurement of the B-mode polarization on sub-degree scales induced by gravitational lensing in December 2013 followed by the first measurement of the B-mode power spectrum on those scales in March 2014. In this proceedings, we review the physics of CMB B-modes and then describe the Polarbear experiment, observations, and recent results.

We describe a survey of nearby core-collapse supernova (SN) explosion sites using integral field spec- troscopy (IFS) techniques, which is an extension of the work described in Kuncarayakti et al. (2013). The project aims to constrain SN progenitor properties based on the study of the immediate environment of the SN. The stellar populations present at the SN explosion sites are studied by means of integral field spectroscopy, which enables the acquisition of both spatial and spectral information of the object simultaneously. The spectrum of the SN parent stellar population gives an estimate of its age and metal- licity. With this information, the initial mass and metallicity of the once coeval SN progenitor star are derived. While the survey is mostly done in optical, the additional utilization of near-infrared integral field spectroscopy assisted with adaptive optics (AO) enables us to examine the explosion sites in high spatial detail, down to a few parsecs. This work is being carried out using multiple 2-8 m class telescopes equipped with integral field spectrographs in Chile and Hawaii.
