Addict Behav 2018 Dec 7;90:421-427. Epub 2018 Dec 7.

Research Institute on Addictions, University at Buffalo, State University of New York, Buffalo, NY, United States. Electronic address:

Associations between anxiety, depression and adolescent Internet addiction have been well documented in the literature; however, few published studies have examined these relationships considering the developmental trajectory courses of adolescent Internet addiction as well as the individual differences over time. Using a sample of 1545 Chinese adolescents and 3 waves of data over six months, we examined the longitudinal associations between anxiety and depression and Internet addiction, considering sex and obesity. We used latent growth curve modeling (LGCM) to examine the overall conditions of Internet addiction, and latent class growth modeling (LCGM) to determine adolescent developmental membership for Internet addiction.

Pingjun Jiang

Health Mark Q 2018 Dec 14:1-18. Epub 2018 Dec 14.

a Department of Marketing, School of Business Administration , La Salle University , Philadelphia , Pennsylvania , USA.

This study examines how consumers who responded to direct-to-consumer (DTC) prescription drug advertising by either talking with their doctors or seeking the Internet differ from those who did not respond to DTC advertising in a number of meaningful ways. This exploratory study provides an initial look at factors that are influential in discriminating information responders from nonresponders to DTC Rx ads. Consumers more attentive to and having more positive attitudes towards Rx ads and consumers having lower trust in their doctors and perceiving higher empowerment by Rx ads are more likely to respond for additional information after seeing Rx ads.

Security Cost Aware Data Communication in Low-Power IoT Sensors with Energy Harvesting.

Sensors (Basel) 2018 Dec 12;18(12). Epub 2018 Dec 12.

School of Computer Science and Engineering, Southeast University, Nanjing 211189, China.

Security is a critical concern in low-power IoT (Internet of Things) wireless sensors because these resource constrained devices are easy to attack and meanwhile the energy constraint sensors will consume a lot of energy to run algorithms for security purposes. We study the energy efficiency data transmission problem in IoT sensors that use capacitors to harvest wireless energy while considering the energy cost for running security algorithms. Energy harvesting with capacitors has the characteristic that the energy harvesting rate varies over time, and it is getting slower and slower as the capacitor gets more and more wireless energy.

UISTD: A Trust-Aware Model for Diverse Item Personalization in Social Sensing with Lower Privacy Intrusion.

Sensors (Basel) 2018 Dec 11;18(12). Epub 2018 Dec 11.

School of Information Science and Engineering, Shandong Normal University, Jinan 250014, China.

Privacy intrusion has become a major bottleneck for current trust-aware social sensing, since online social media allows anybody to largely disclose their personal information due to the proliferation of the Internet of Things (IoT). State-of-the-art social sensing still suffers from severe privacy threats since it collects users' personal data and disclosure behaviors, which could raise user privacy concerns due to data integration for personalization. In this paper, we propose a trust-aware model, called the User and Item Similarity Model with Trust in Diverse Kinds (UISTD), to enhance the personalization of social sensing while reducing users' privacy concerns.

J Med Internet Res 2018 Dec 6;20(12):e11817. Epub 2018 Dec 6.

Department of Biomedical Data Science, Dartmouth College, Lebanon, NH, United States.
