Abstract: Many content systems (e.g., social networks) present to a user a set of content items posted by other individuals. The user may selectively view content items that reinforce and are consistent with the user's perspective, creating an “echo chamber” effect. Conversely, content systems that selectively expose users to content items exhibiting contrary perspectives, and from individuals with no connection with the user, may alienate the user. Presented herein are techniques for recommending content items that present a different perspective from that of the user, and from individuals who share a similar profile to the user (e.g., alternative opinions from other individuals within the user's social circle or community). Optionally, opinions may be selected that do not directly oppose the user's perspective, but that are orthogonal with it. Such selective recommendations may persuade the user to consider contrary viewpoints that may alter the user's perspective while reducing user alienation.

Abstract: A transparent rigid-material container (1), has an access mouth (11) and is fitted with a closing cover (2) with a rear appendix (21) for coupling, in an axial direction, with the container mouth (11); with the container mouth (11) and the rear appendix (21) of the cover presenting similar, irregular outlines for coupling in a single position; and the cover (21) includes an electronic circuit (3) that includes an electronic control card (31), and a data memory (33), a data entry and downloading arrangement (32a, 32b, 32c), a data display screen (34), an electric battery (35) and a low-consumption electromechanical lock (36), all connected with the data memory (33).

Abstract: A hospital identification bracelet includes a flexible strip (1) with several self-adhesive labels (2) for receiving printed or printable bar codes, a writable area (5) for patient data and the label codes, together with a simple closing device, and a RFID transponder (6) of Identification by Radio Frequency, fixed to the flexible strip (1) and on which the corresponding code is printed with the self-adhesive label codes (2) in a biunivocal manner. The flexible strip (1) presents perforation lines (3) for the independent separation of the self-adhesive labels (2) with the printed or printable codes.
