Emergency Preparedness and Community Policing Within Campus Law Enforcement Agencies
Campus law enforcement agencies are an essential component of the campus community, and the greater criminal justice system. While policing research has focused on the activities and organizational structure of municipal police, much less attention has been given to campus agencies. This study builds on existing research by examining the activities and organizational structures of campus law enforcement agencies. The purpose of this quantitative nonexperimental study was to analyze the variation in emergency preparedness across campus law enforcement agencies using Meyer and Rowan\u27s institutional theory. The research questions addressed the extent to which emergency preparedness was influenced by organizational structural, agency characteristics, wider campus characteristics, and community policing. Secondary data were collected from the 2011-2012 Bureau of Justice Statistics Survey of Campus Law Enforcement Agencies, the Office of Postsecondary Education, and the National Center for Education Statistics. Findings from multiple regression analyses indicated that agency organizational structure and agency characteristics are greater influences than campus characteristics on emergency preparedness activities than campus. Findings also showed that the number of community policing activities in which an agency engages in is the greatest predictor of emergency preparedness activities in campus law enforcement agencies. The findings have implications for social change by suggesting the integration of emergency preparedness with community policing initiatives. Collectively, this will create a holistic approach by campus law enforcement agencies
A Precision Calculation of the Next-to-Leading Order Energy-Energy Correlation Function
The O(alpha_s^2) contribution to the Energy-Energy Correlation function (EEC)
of e+e- -> hadrons is calculated to high precision and the results are shown to
be larger than previously reported. The consistency with the leading logarithm
approximation and the accurate cancellation of infrared singularities exhibited
by the new calculation suggest that it is reliable. We offer evidence that the
source of the disagreement with previous results lies in the regulation of
double singularities.Comment: 6 pages, uuencoded LaTeX and one eps figure appended Complete paper

Examining the Effects of Perceptions of Voter Suppression and Voter Fraud on Support for Voter Identification Laws in the United States
Democracy is fundamentally grounded in the people's right to vote, but what happens when the same mechanisms meant to protect the electoral process become barriers? This study examined the relationship between perceptions of voter suppression and voter fraud and support for voter restrictions, such as requiring identification to vote. The study utilized data from the American National Election Studies 2020 Times Series Study, examining a sample of 5,264 voters. Results revealed that voter support for voter ID laws depends on their perceptions of voter integrity and suppression. The more confidence voters have in the integrity of elections and the more they believe in voter suppression, the less likely they are to support voter identification requirements. Other demographic factors are considered
The Scaled Arrival of K-12 Online Education: Emerging Realities and Implications for the Future of Education
Bioinfo PublicationsDramatic increases in K—12 online education for all students,
including those in traditionally underserved populations, necessi2
tate a reconceptualization in the way educators plan and implement
instruction. In this article the authors examine the complex array of
variables and implementation models that must be accounted for
during the pivot from a purely brick-and-mortar educational sys2
tem to one that makes use of both virtual and blended environ2
ments. The authors call for enhanced emphasis on instructional
goals and design principles, rather than the capabilities of available
technology. They conclude that educational leaders and researchers
must play a role in three key areas: using technology to enhance the
accessibility and usability of curricular materials to meet the needs
of different types of learners, advancing the understanding and
practices of in-service and pre-service teachers through preparation
that focuses on online learning, and fostering collaboration between
educational researchers and technology innovators and developers
to build a research base that will inform K—12 online education
Math and Coding Connections in Elementary
In this session, participants learn ways to use coding tools in elementary classrooms to provide engaging and motivating contexts for students to develop and use mathematical and computational reasoning. Integrating technology to support mathematics learning in meaningful ways is often challenging, and discussions in this session will emphasize the synergies among technology, coding, and mathematics for supporting skills with coding tools
Diamond: The Game – a board game for secondary school students promoting scientific careers and experiences
Diamond: The Game is a board game designed for secondary school students (aged 11–18) to enable them to explore a broad variety of science, technology, engineering and mathematics (STEM) careers, STEM subjects and life as a scientist. Board games are a reusable and entertaining way to directly engage students in STEM, but careful consideration of mechanics, messages and accessibility is required to successfully deliver on this goal. Diamond: The Game was designed and evaluated against these considerations. The inclusive approach to design resulted in a better and more accessible game for all. Its success is further evident in the rise in the number of players who would consider a career as a scientist or an engineer after playing. The opportunities to explore collaboration, failure and the interdisciplinary nature of science in the game were particularly highlighted in discussions with students, teachers and careers advisers
Effects of Color Attributes on Trap Capture Rates of Chrysobothris femorata (Coleoptera: Buprestidae) and Related Species
Chrysobothris spp. (Coleoptera: Buprestidae) and other closely related buprestids are common pests of fruit, shade, and nut trees in the United States. Many Chrysobothris spp., including Chrysobothris femorata, are polyphagous herbivores. Their wide host range leads to the destruction of numerous tree species in nurseries and orchards. Although problems caused by Chrysobothris are well known, there are no reliable monitoring methods to estimate local populations before substantial damage occurs. Other buprestid populations have been effectively estimated using colored sticky traps to capture beetles. However, the attraction of Chrysobothris to specific color attributes has not been directly assessed. A multi-color trapping system was utilized to determine color attraction of Chrysobothris spp. Specific color attributes (lightness [L*], red to green [a*], blue to yellow [b*], chroma [C*], hue [h*], and peak reflectance [PR]) were then evaluated to determine beetle responses. In initial experiments with mostly primary colors, Chrysobothris were most attracted to traps with red coloration. Thus, additional experiments were performed using a range of trap colors with red reflectance values. Among these red reflectance colors, it was determined that the violet range of the electromagnetic spectrum had greater attractance to Chrysobothris. Additionally, Chrysobothris attraction correlated with hue and b*, suggesting a preference for traps with hues between red to blue. However, males and females of some Chrysobothris species showed differentiated responses. These findings provide information on visual stimulants that can be used in Chrysobothris trapping and management. Furthermore, this information can be used in conjunction with ecological theory to understand host-location methods of Chrysobothris
Causality constraints in AdS/CFT from conformal collider physics and Gauss-Bonnet gravity
We explore the relation between positivity of the energy constraints in
conformal field theories and causality in their dual gravity description. Our
discussion involves CFTs with different central charges whose description, in
the gravity side, requires the inclusion of quadratic curvature corrections. It
is enough, indeed, to consider the Gauss-Bonnet term. We find that both sides
of the AdS/CFT correspondence impose a restriction on the Gauss-Bonnet
coupling. In the case of 6d supersymmetric CFTs, we show the full matching of
these restrictions. We perform this computation in two ways. First by
considering a thermal setup in a black hole background. Second by scrutinizing
the scattering of gravitons with a shock wave in AdS. The different helicities
provide the corresponding lower and upper bounds. We generalize these results
to arbitrary higher dimensions and comment on some hints and puzzles they
prompt regarding the possible existence of higher dimensional CFTs and the
extent to which the AdS/CFT correspondence would be valid for them.Comment: 31 pages, 5 figures; v2: typos fixed, cosmetic amendments and
