Social media and the resulting tidal wave of the available data have changed the ways and methods researchers analyze communities at scale. But the full potential for social scientists (and others) is not yet achieved. Despite the popularity of social media analysis in the past decade, few researchers invest in cross-platform analyses. This is a ma...

With the coming of the 21st century in the U.S., reliance on fossil fuels, in particular coal, decreased while renewable energy sources increased their contribution to the U.S. energy portfolio. The factors behind this emerging trend toward a decreased reliance on coal are many, including economic as well as policy goals. Nationally, support is str...

Research Methods is a frequently-unloved course for students and instructors alike. However, successful research methods courses are linked to high-value and long-term outcomes such as stronger career preparation and higher information literacy. We propose reimaging Research Methods courses for Information Systems and Information Technology degrees...
Article
The staggering increase in the amount of information on the World Wide Web (referred to as Web) has made Web page classification essential to retrieve useful information while filtering out unwanted, futile, or harmful contents. This massive information-sharing platform is occasionally abused for propagating extreme and radical ideologies and posin...

Interest in curiosity research has blossomed over the last decade, particularly in neuroscience and psychology, and its value to organizations is strongly emphasized nowadays (Lievens, Harrison, Mussel, & Litman, 2021). Curiosity in organizations is often seen as a trigger for innovation and fosters personal and organizational adaptability. Thus, i...

The Work-Learn project addresses three novel gaps in IS research: generalizability of online learning tools; tech workforce development; and how IS research can contribute to the emergent trans-discipline focus on empirical validation in social justice programming. Disparities in accessing online education are an example of how adults experiencing...

Many countries plan to decarbonise their energy systems by increasing energy efficiency and expanding the use of renewable energy sources (RES). Such actions require significant investments in new energy infrastructures. While people are generally accepting of these infrastructures, opposition sometimes arises when these developments are sited at c...

A socialoid (our term) is an integrated collection of data and models about a society. As such, and accepting that it can never be complete, it is a computational model of a society. We are in the early stages of building a socialoid for Philadelphia, PA. We call it the Philadelphioid. The Philadelphioid is a diachronic (temporal), mashed, geograph...

Between 2007 and 2016, there were 144,002 HAZMAT incidents on US highways, with damage totaling nearly $600 M. The top two incident types in the past three years involved flammable-combustible liquids and corrosive materials. In 2016, 38% of firefighter fatality was a result of sudden cardiac death, making it one of the two leading causes of death...

Experiential learning posits that learning occurs on the basis of practice; in technology courses this is often practiced as real or near to real life projects. Successful student-led project implementation has multiple definitions in the undergraduate learning context. In the best of cases, all stakeholders including students, instructors, communi...

The Internet has made it effortless to find advice, opinions, support, and information. Social media plays a supporting role by transferring such content between people, companies, doctors, and other actors instantly. When it comes to cancer diagnoses, researchers do not know who looks for what types of information and interactions on which website...

Benford's law shows the pattern of behavior in normal systems. It states that in natural systems digits' frequency have a certain pattern such that the occurrence of first digits in numbers are unevenly distributed. In systems with natural behavior, numbers begin with a "1" are more common than numbers beginning with "9". It implies that if the dis...

The advent of the Internet inadvertently augmented the functioning and success of violent extremist organizations. Terrorist organizations like the Islamic State in Iraq and Syria (ISIS) use the Internet to project their message to a global audience. The majority of research and practice on web‐based terrorist propaganda uses human coders to classi...
Conference Paper
Agile software development is a popular approach which focuses on creating small working pieces of software in iterations. One of its major benefits is that it allows customers to provide feedback and change requirements during the development phase. This can lead to outcomes that better match their specifications, which can help save time and mone...
Conference Paper
Individuals in diaspora tend to engage and interact with the people of their origin. Afghans in the 1980s and 90s, one of the largest diaspora communities, used traditional channels such as Radio and Television to communicate with their loved ones inside Afghanistan.

Social networks attract much attention due to their ability to replicate social interactions at scale. Link prediction, or the assessment of which unconnected nodes are likely to connect in the future, is an interesting but non-trivial research area. Three approaches exist to deal with the link-prediction problem: feature-based models, Bayesian pro...

A dilemma in urban mobility with tremendous effects on citizens’ well-being is the unconscious antipode between their short- and long-term goals.
