A Survey on Purchase Intention of Hello Barbie in Brazil and Argentina
No full textChildren's toys have become increasingly sophisticated over the years, with a growing shift from simple physical products to toys that engage the digital world by the use of software and hardware. A smart toy, such as Hello Barbie, is defined as a device consisting of a physical toy component that connects to a computing system with online services through networking to enhance the functionality of a traditional toy. Hello Barbie is introduced by Mattel as ?the first fashion doll that can have a two-way conversation with girls? with speech recognition and online connection to Cloud computing technologies. While the doll is made by Mattel, the online English conversation software is powered by ToyTalk.com. The targeted players are 7?13 years old children. Adding the ability of speech recognition and online connection raises the risk of privacy breaches in children. Since its introduction in February 2015, Hello Barbie has been criticized for the negative effects on children along with privacy concerns in the United States How will consumers in other countries react to this type of smart toys. The main objective of this paper is to present a survey of purchase intention of Hello Barbie in Brazil and Argentina, where consumers still have not been massively presented to this type of smart toy. Our results indicate that Brazilian consumers have better perception and evaluation of the toy and thus higher purchase intention toward the toy than Argentinian consumers do. Such difference is explained by the culture differences between the two countries, such as relatively low vs. high uncertainty avoidance.Fil: Fantinato, Marcelo.

Towards Standardized Web Services Privacy Technologies
No full textA Web service is defined as an autonomous unit of application logic that provides either some business functionality or information to other applications through an Internet connection. Web services are based on a set of XML standards such as Universal Description, Discovery and Integration (UDDI), Web Services Description Language (WSDL), and Simple Object Access Protocol (SOAP). Recently there are increasing demands and discussions about Web services privacy technologies in the industry and research community. In general, privacy policies describe an organization's data practices what information they collect from individuals (e.g., consumers) and what (e.g., purposes) they do with it. To enable privacy protection for Web service consumers across multiple domains and services, the World Wide Web Consortium (W3C) published a document called "Web Services Architecture (WSA) Requirements" that defines some specific privacy requirements for Web services as a future research topic. At this moment, there is still no standardized Web services privacy technology. This paper briefly overviews the research issues of Web services privacy technologies

Towards Propagation of Changes by Model Approximations
No full textA number of model transformation approaches have been proposed both from academia and industry since automated manipulation of models plays a central role in model driven development. Ideally, a model transformation technique should also be compatible with manual changes that might be performed by designers on the generated models in order to resolve unforeseen requirements or limited expressiveness of the involved metamodels. This paper proposes an approach to model transformation based on answer set programming. Starting from target models that have been manually modified (and possibly not belong to the co-domain of the transformation being used), the approach is able to deduce a collection of models that approximate the ideal one from which it is possible to generate the previously modified target. © 2006 IEEE
Failure location in WDM networks
No full textFault identification and location in optical networks must cope with a multitude of factors: (i) the redundancy and the lack of coordination (internetworking) of the managements at the different layers (WDM, SDH/SONET, ATM, IP); (ii) the large number of alarms a single failure can trigger; (iii) the difficulty in detecting some failures and the resulting need to cope with missing or false alarms. This chapter first details the behavior of network components in transparent WDM networks when a failure occurs. Using this model, we then describe an efficient algorithm (Fault Location Algorithm, FLA) pointing out the element(s) which is (are) most likely to be the cause of the received alarms. Although the problem of multiple failure diagnosis is known to be NP-hard, the non-polynomial complexity of the algorithm is pushed ahead in a pre-computational phase, which can be done off-line, and not at the time of a failure. The diagnosis phase is therefore very rapid. We discuss the time and space complexity of the FLA.Carmen Mas, Hung X. Nguyen and Patrick Thira
Structure of a rare non-standard sequence k-turn bound by L7Ae protein
No full textKt-23 from Thelohania solenopsae is a rare RNA kink turn (k-turn) where an adenine replaces the normal guanine at the 2n position. L7Ae is a member of a strongly conserved family of proteins that bind a range of k-turn structures in the ribosome, box C/D and H/ACA small nucleolar RNAs and U4 small nuclear RNA. We have solved the crystal structure of T. solenopsae Kt-23 RNA bound to Archeoglobus fulgidus L7Ae protein at a resolution of 2.95 Å. The protein binds in the major groove displayed on the outer face of the k-turn, in a manner similar to complexes with standard k-turn structures. The k-turn adopts a standard N3 class conformation, with a single hydrogen bond from A2b N6 to A2n N3. This contrasts with the structure of the same sequence located in the SAM-I riboswitch, where it adopts an N1 structure, showing the inherent plasticity of k-turn structure. This potentially can affect any tertiary interactions in which the RNA participates. © The Author(s) 2014. Published by Oxford University Press</p
