BACKGROUND
Initial reports suggest that JUUL, a popular e‐cigarette, is being used in schools and other locations in which cigarette smoking is illegal or discouraged. However, there is little scholarly research documenting this. We aimed to make a systematic analysis of JUUL use themes and sentiment on Twitter.
METHODS
Data were collected from Twitter's Filtered Streams Application Programming...
Background Adolescence and young adulthood are critical times of initiation and progression to daily use of tobacco. However, it is difficult to recruit young adults to traditional smoking cessation and retention rates are typically low. Smartphone cessation applications (apps) can provide real-time responses to smoking urges and related cues, which are known to be important factors in lapse and relapse...
This study applies diffusion of innovations theory to understand network influences on country ratification of an international health treaty, the Framework Convention for Tobacco Control (FCTC). From 2003 to 2014 approximately 90% of United Nations member countries ratified the FCTC. We hypothesized that communication between tobacco control advocates on GLOBALink, a 7000-member online communication...
In 2011, the Los Angeles County Department of Public Health began a prevention services initiative to address problems dealing with alcohol and other drugs across the County. A major component of the strategy included the formation of eight coalitions. Defined by geographic borders, each coalition consisted of multiple service provider organizations, and were mandated to implement customized plans...
Socio-technical networks that are heterogeneous in composition of actors and the media through which they interact are becoming common, but opportunities to study the emergent community structure of such networks are rare. We report a study of an international online network of educators involved in many forms of professional development and peer support, including sponsored and volunteer-driven activities...
This work presents an exploratory study of the different types of technology-mediated relationships that are formed in a sociotechnical system. More people each day are connecting with each other through social networks, online communities, and other forms of virtual environments. This study offers a framework for understanding how technology, user interactions, and user relationships are connected...
People interact in a variety of ways, and often choose what media to use based on the relationships they have with their interlocutors. Similarly, there are different ways through which people are associated in socio-technical networks or "online communities." This paper reports a study that characterizes how the associations between members of a socio-technical network--the Tapped In network...
Activities in online communities are often distributed across multiple media and sites. Additionally, the granularity at which events are recorded may not match the analytic needs. Since communication is scattered across space, time, and media, and the data comes in a variety of formats, there is no single transcript to inspect and share, and the available data representations may not make interaction...
Tie measurement is an analytic foundation of social network analysis, and has been most commonly measured in regards to the strength of the tie. The strong tie - weak tie dichotomy is conceptually misleading, and the science of networks lacks a clear conceptualization of ties that allows for consistent operationalization of the concept. This conceptual gap has led researchers to measure ties in a...
This work is based on the premise that online learning environments can potentially help develop communities of scholars by enabling participants to discover persons and resources from contexts other than the original course to which they were assigned. Our software, Prometheus, is being used to support online university level education and teacher professional development under an open community...
The automobile industry has produced many cars with new features over the past decade. However, the interaction between the driver and the car has not changed significantly. The information being delivered - both in quantity and method - from the car to the driver has not seen the same improvements as there have been "under the hood." This paper proposes immersing the driver inside an additional...
