Customer perceptions of Japanese foods in Italy

Rosa M. Fanelli,Angela Di Nocera 한국식품연구원 2018 Journal of Ethnic Foods Vol.5 No.3

As we all know, online consumer reviews have come to substitute more traditional forms of restaurant criticism. In this article, we examine the significance of TheFork for the reputation of Japanese restaurants in Italy. Data were extracted from the websites of restaurants associated with TheFork. A total of 675 online reviews were analyzed. The study focused on statistical inquiry using principal component analysis and analysis of variance to answer the following research question: Does a statistically significant relationship exist between the attributes of Japanese restaurants and reviewer profiles? The results highlighted two elements, which were successfully constructed: the reviewer's profile and the attributes of Japanese restaurants.

Recent technological advances provide the opportunity to use large amounts of multimedia data from a multitude of sensors with different modalities (e.g., video, text) for the detection and characterization of criminal activity. Their integration can compensate for sensor and modality deficiencies by using data from other available sensors and modalities. However, building such an integrated system at the scale of neighborhood and cities is challenging due to the large amount of data to be considered and the need to ensure a short response time to potential criminal activity. In this paper, we present a system that enables multi-modal data collection at scale and automates the detection of events of interest for the surveillance and reconnaissance of criminal activity. The proposed system showcases novel analytical tools that fuse multimedia data streams to automatically detect and identify specific criminal events and activities. More specifically, the system detects and analyzes series of incidents (an incident is an occurrence or artifact relevant to a criminal activity extracted from a single media stream) in the spatiotemporal domain to extract events (actual instances of criminal events) while cross-referencing multimodal media streams and incidents in time and space to provide a comprehensive view to a human operator while avoiding information overload. We present several case studies that demonstrate how the proposed system can provide law enforcement personnel with forensic and real time tools to identify and track potential criminal activity.

<P>Enhanced synthetic control of the morphology, crystal structure, and composition of nanostructures can drive advances in nanoscale devices. Axial and radial semiconductor nanowires are examples of nanostructures with one and two structural degrees of freedom, respectively, and their synthetically tuned and modulated properties have led to advances in nanotransistor, nanophotonic, and thermoelectric devices. Similarly, developing methods that allow for synthetic control of greater than two degrees of freedom could enable new opportunities for functional nanostructures. Here we demonstrate the first regioselective nanowire shell synthesis in studies of Ge and Si growth on faceted Si nanowire surfaces. The selectively deposited Ge is crystalline, and its facet position can be synthetically controlled <I>in situ</I>. We use this synthesis to prepare electrically addressable nanocavities into which solution soluble species such as Au nanoparticles can be incorporated. The method furnishes multicomponent nanostructures with unique photonic properties and presents a more sophisticated nanodevice platform for future applications in catalysis and photodetection.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/jacsat/2013/jacsat.2013.135.issue-49/ja411050r/production/images/medium/ja-2013-11050r_0005.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/ja411050r'>ACS Electronic Supporting Info</A></P>

<P><B>Significance</B></P><P>Patterning large substrate areas with arrays of submicrometer structures in a facile, reliable, and timely manner is important for fabrication of optical elements that capture, guide, and convert light. RIPPLE (reactive interface patterning promoted by lithographic electrochemistry) is an electrochemical patterning method that is demonstrated for the rapid fabrication of periodic arrays of metallic circular Bragg gratings over large substrate areas. The grating period can be tuned in situ over micrometer and submicrometer length scales in a high-throughput fashion. We have identified point-like and annular scattering modes at different planes above the structured surface, suggesting the potential to use such structures to control the propagation of light. The described methods may be useful for high-throughput fabrication of sensors and light-management elements for energy conversion applications.</P><P>A patterning method termed “RIPPLE” (reactive interface patterning promoted by lithographic electrochemistry) is applied to the fabrication of arrays of dielectric and metallic optical elements. This method uses cyclic voltammetry to impart patterns onto the working electrode of a standard three-electrode electrochemical setup. Using this technique and a template stripping process, periodic arrays of Ag circular Bragg gratings are patterned in a high-throughput fashion over large substrate areas. By varying the scan rate of the cyclically applied voltage ramps, the periodicity of the gratings can be tuned in situ over micrometer and submicrometer length scales. Characterization of the periodic arrays of periodic gratings identified point-like and annular scattering modes at different planes above the structured surface. Facile, reliable, and rapid patterning techniques like RIPPLE may enable the high-throughput and low-cost fabrication of photonic elements and metasurfaces for energy conversion and sensing applications.</P>
