Public Trust in State-Run News Media in Rwanda
No full textThis study examined public trust in the media through focus groups with young, educated urbanites in Rwanda. Despite the fact media in Rwanda incited violence during the 1994 genocide, results revealed that the Rwandan public highly trust their local news, especially state-run media. The findings suggest frameworks for studying media trust should consider the public’s trust in government, as the two might be linked, and also suggest scholars think deeply about conceptualizations of trust in different socio-political contexts, as trust is part of the culture of a polity, not simply a citizen’s judgment on how well news media are doing
Media and money: a 50-year analysis of international news coverage and U.S. foreign aid
No full textThis study compared 50 years of the New York Times’ international news (N = 20,765) with U.S. foreign aid allocations and country rankings in Freedom House\u27s Freedom in the World report to understand how the amount of foreign aid relates to the amount and content of coverage of nations as well as whether/how political similarity impacts coverage and aid. Nations receiving the highest level of aid received the most news coverage and topics of coverage focused significantly more on politics, conflict and diplomacy. Coverage of nations that receive a high level of aid was largely split between free, partly free and not free, pointing to media attention not necessarily being linked to freedom status
Trust Models and Risk in the Internet of Things
No full textThe Internet of Things (IoT) is envisaged to be a large-scale, massively heterogeneous ecosystem of devices with varying purposes and capabilities. While architectures and frameworks have focused on functionality and performance, security is a critical aspect that must be integrated into system design. This work proposes a method of risk assessment of devices using both trust models and static capability profiles to determine the level of risk each device poses. By combining the concepts of trust and secure device fingerprinting, security mechanisms can be more efficiently allocated across networked IoT devices. Simultaneously, devices can be allowed a greater degree of functionality while ensuring system availability and security. This paper describes the integration of risk assessment into a prototype IoT network. The purpose of this prototype is to explore whether finer-grained security policies based on risk can adequately protect the network while also allowing for efficiency and system functionality to a greater extent than traditional security protocols permit. Furthermore, we demonstrate how identification, trust, and risk can be synthesized to provide a finer degree of control over system security
Linking genetics, microbiology & molecular biology courses to provide research experiences in undergraduate biology
No full textCourse-based undergraduate research experiences (CUREs) can have benefits for many students, especially those who lack access to traditional apprenticeships for research. As part of an effort to create more opportunities for students to have access to primary research and move away from traditional cookie-cutter labs, we have created a multicourse CURE spanning three undergraduate teaching labs in which students can pick and choose to take any of the courses that most interest them. This CURE explores the essential understanding of the emergence of antibiotic-resistant bacteria as well as high-throughput sequencing and mutagenesis screens. These low-cost modular labs are designed to be flexible and integrated into any single teaching lab to increase exposure to both fundamental lab skills and primary research
Hip Joint Contact Loading and Muscle Forces during Running with a Transtibial Amputation
No full textPeople with unilateral transtibial amputations (TTA) have greater risks of bilateral hip osteoarthritis, related to asymmetric biomechanics compared to people without TTA. Running is beneficial for physical health and is gaining popularity. However, people with TTA may not have access to running-specific prostheses (RSPs), which are designed for running, and may instead run using their daily-use prosthesis (DUP). Differences in joint loading may result from prosthesis choice; thus, it is important to characterize changes in peak and impulsive hip joint contact loading during running. Six people with and without TTA ran at 3.5 m/s while ground reaction forces, kinematics, and electromyography were collected. People with TTA ran using their own RSP and DUP. Musculoskeletal models incorporating prosthesis type of each individual were used to quantify individual muscle forces and hip joint contact forces (HJCFs) during running. People using RSPs had smaller bilateral peak hip joint contact forces compared to when wearing DUPs during stance and swing, and a smaller impulse over the entire gait cycle. Greater amputated leg peak hip joint contact forces for people wearing DUPs compared to RSPs occurred with greater forces from the ipsilateral gluteus maximus during stance. People with TTA also had greater bilateral peak hip joint contact forces during swing compared to people without TTA, which occurred with greater peak gluteus medius forces. Running with more compliant RSPs may be beneficial for long-term joint health by reducing peak and impulsive hip loading compared to DUPs
My Mental Health Struggle in Academia: What I Wish All Business School Faculty, Students, and Administration Knew
No full textThis article deals with my experience of struggling with mental health while trying to succeed in a management department. I will explore the realities of working as an academic in a business school, my experience as a new faculty member with mental health issues, the stigma I encountered, and how mental illness has challenged my opportunity for advancement. Finally, I will discuss some ideas on how to create a better environment for all and especially for people who struggle with mental health issues as well as the benefits of that environment for both universities and students
Project Recuerdo: Honoring Latinx Families’ Knowledge Within the School
No full textThe authors describe a culturally sustaining bilingual family engagement project that draws upon Latinx families’ experiential and cultural wealth and integrates that knowledge within the literacy curriculum of a bilingual fourth grade classroom. Through the use of monthly writing prompts, Project Recuerdo, engages families in sharing stories that demonstrate cultural, linguistic, and historical knowledge with the child, teacher, and wider community. This form of family engagement counters deficit orientations towards diverse families, especially Mexican American families, as problems to fix, and instead honors the wealth of knowledge families have and integrates it within the curriculum. Through the analysis of the bilingual journal entries, related classroom artifacts, and family focal groups, the authors validate the importance of learning with and from diverse families; and detail the process for planning the implementation of the family project. Authors provide suggestions for teacher self-reflection and possible writing prompts to engage families
Magnetic-field measurement and analysis for the Muon g-2 Experiment at Fermilab
No full textThe Fermi National Accelerator Laboratory (FNAL) Muon g-2 Experiment has measured the anomalous precession frequency aμ(gμ-2)/2 of the muon to a combined precision of 0.46 parts per million with data collected during its first physics run in 2018. This paper documents the measurement of the magnetic field in the muon storage ring. The magnetic field is monitored by systems and calibrated in terms of the equivalent proton spin precession frequency in a spherical water sample at 34.7C. The measured field is weighted by the muon distribution resulting in ωp′, the denominator in the ratio ωa/ωp′ that together with known fundamental constants yields aμ. The reported uncertainty on ωp′ for the Run-1 data set is 114 ppb consisting of uncertainty contributions from frequency extraction, calibration, mapping, tracking, and averaging of 56 ppb, and contributions from fast transient fields of 99 ppb
