Exploring Crisis Communication And Information Dissemination On Social Media: Social Network Analysis Of Hurricane Irma Tweets, Xianlin JIn 2020 University of Kentucky

Exploring Crisis Communication And Information Dissemination On Social Media: Social Network Analysis Of Hurricane Irma Tweets, Xianlin Jin

Journal of International Crisis and Risk Communication Research

This study utilized social network analysis to identify the top 10 Twitter influentials during the Hurricane Irma crisis period and examined the relationship between social media attributes and the bridge influence of controlling information flow. The number of a user’s followers and tweets significantly predicted one’s control of information. Crisis information tended to be shared in scattered subgroups. Social network boundaries impeded information diffusion, and the communication pattern was largely one-way. The findings partially supported the opinion leader argument while indicating that influentials can directly generate information, which is consistent with the social-mediated crisis communication model. Such findings ...


Gender And Presence Of Children: Examining Media Uses, Informational Needs, And Source Preferences During The Flint, Michigan Water Crisis, Ashleigh M. Day, Sydney O'Shay-Wallace, Matthew W. Seeger, Shawn P. McElmurry 2020 The University of Texas at Tyler

Gender And Presence Of Children: Examining Media Uses, Informational Needs, And Source Preferences During The Flint, Michigan Water Crisis, Ashleigh M. Day, Sydney O'Shay-Wallace, Matthew W. Seeger, Shawn P. Mcelmurry

Journal of International Crisis and Risk Communication Research

In 2014, a water crisis emerged in Flint, Michigan. Using uses and gratifications theory as the guiding framework, this study examines if crisis-related media uses, informational needs, and source preferences are related to respondents’ gender and/or whether or not respondents had children. A random sample of 208 Flint residents yielded results that are largely consistent with extant research, although minor nuances were found. Media uses, preferred informational sources, and desire to receive future crisis-related health information varied between women and men. Women reported significantly higher use of Facebook and Instagram. However, there were not significant differences between genders or ...

Ruggedized Color Measurement For Beer, Wort, And Malt, Roger Barth, Randall H. Reiger, Yuki Kim 2020 West Chester University of Pennsylvania

Ruggedized Color Measurement For Beer, Wort, And Malt, Roger Barth, Randall H. Reiger, Yuki Kim

Chemistry Faculty Publications

The standard instrument for measuring malt, wort, and beer color is the spectrophotometer. Spectrophotometers are not rugged; they have critically aligned collimators, monochromators, lenses, slits, and mirrors that make them difficult to use and maintain in a production environment. Our research shows that wort and beer color can be measured accurately with rugged equipment based on light emitting diodes (LEDs) with results in agreement with those of a spectrophotometer. Two or more colored diodes were used. LED-based apparatus does not require critical alignment, is not highly sensitive to environmental conditions such as temperature, moisture, dust, and vibration, and can be ...

Data Is Personal: We Should Treat It As Such, Kaleb Dunn 2020 Purdue University

Data Is Personal: We Should Treat It As Such, Kaleb Dunn

Student Papers in Public Policy

The rise of the internet as a fact of daily life is the defining element of the modern age. Widespread use of the internet has fundamentally altered entire industries, and much of American life has migrated online. Dating is augmented by online dating; shopping by online shopping; television by internet streaming.

The digitization of American life has brought with it considerable benefits, including great convenience and innumerable efficiencies, but it has not come without a cost. Although there are many business models used by internet companies, many of the now-largest companies in the world have converged on one entity upon ...


Implement Multi-Factor Authentication On All Federal Systems Now, Megan Walsh 2020 Purdue University

Implement Multi-Factor Authentication On All Federal Systems Now, Megan Walsh

Student Papers in Public Policy

The White House Office of Management and Budget recorded 31,107 information security incidents in fiscal year 2018. The most common attacks to gain access to a user’s login credentials were e-mail/phishing, web-based attack, and brute force entering of username/password combinations. Given this high number of incidents, strong reliance on computers for everyday business, and common attacks that target passwords, information security should be a priority for information technology administrators working in federal agencies.


Removing Racially Biased Algorithms In Policing, Andie Lee 2020 Purdue University

Removing Racially Biased Algorithms In Policing, Andie Lee

Student Papers in Public Policy

Local police departments use algorithm-based programs to do police work and predict crime. Technology has created the police tactic of predictive crime prevention. Police work, however, requires social skills, assessment of the environment, and most importantly human interaction. Automated policing lacks these characteristics. Moreover, the algorithms used to make crime predictions and risk assessments have disproportionately affected minorities.


The Case For Online Ranked-Choice Voting, Rayyan Khan 2020 Purdue University

The Case For Online Ranked-Choice Voting, Rayyan Khan

Student Papers in Public Policy

Maine was the first to embrace ranked-choice voting on a statewide level in 2018, using it for all state and general elections. Maine voters will be the first to use ranked-choice voting in a presidential election in 2020. This system differs from traditional voting in that voters rank candidates rather than choose just one. Supporters of ranked-choice voting tout it as a better model for accurately representing the values of the voting population; however, a study conducted in San Francisco details a potential shortfall referred to as “ballot fatigue” that the theoretically-ideal system may face as it struggles to deal ...

Faunal Remains From Archaeology Sites In Southwestern New Mexico, Karen Gust Schollmeyer, S. O. Macdonald

Occasional Papers

This study attempts to create a comprehensive catalog of all known records of faunal remains recovered from 105 archaeological sites located across southwestern New Mexico. These sites range in age from 2000BC to AD 1450. Approximately 250 taxa of mollusks, fishes, amphibians, reptiles, birds and mammals are represented in this compilation. Primary reference materials from published and unpublished sources are included, along with the repositories where relevant collections may be found for potential reexamination by researchers from a variety of fields of interest.
