Employment, Poverty, and Public Assistance in the Rural United States

In this brief, authors Rebecca Glauber and Andrew Schaefer provide a glimpse of the economic and demographic characteristics of life in the rural United States. Using data from the American Community Survey, they compare those living in low- and lower-middle-income counties to those living in upper-middle- and high-income counties. Additionally, they compare counties at the extremes, where median incomes are in the bottom and top 10 percent of the income distribution. They report that nearly 75 percent of low-income rural counties in the United States are in the South. Compared to lower-income rural counties, higher-income rural counties have a larger share of immigrants but a smaller share of non-native speakers. One-fifth of immigrants in low-income rural counties do not speak English, compared to just one-twentieth of immigrants in high-income rural counties. People living in poorer rural counties rely more heavily than those living in more well-off rural counties on public-sector supports, and they are less likely to work. Although policy makers tend to focus on people living in the urban United States, the authors’ results show that those living in the rural United States, and particularly in low-income counties, may have even more to gain from public health insurance and other social safety-net programs

Exploring the Relationship between Facebook, Face-to-Face and Intercultural Communication

My Capstone Experience/Thesis project seeks to explore and examine the effects of Facebook on communication between American and international students. The use of social media as a means to communicate with others is increasing at an amazing rate. Facebook has become my generation’s favorite way to communicate with friends and family and “to Facebook” has unofficially become a verb that many college students will use. While social media, such as Facebook and Linked-In, may encourage American college students to communicate with international students beyond the classroom and campus, it seems that Facebook is on the way to becoming a substitute for face to face intercultural interactions. Whether it will enhance or diminish the extent and quality of intercultural communication is an important question to be studied

Mental Representations in Musical Processing and their Role in Action-Perception Loops

Music is created in the listener as it is perceived and interpreted - its meaning derived from our unique sense of it; likely driving the range of interpersonal differences found in music processing. Person-specific mental representations of music are thought to unfold on multiple levels as we listen, spanning from an entire piece of music to regularities detected across notes. As we track incoming auditory information, predictions are generated at different levels for different musical aspects, leading to specific percepts and behavioral outputs, illustrating a tight coupling of cognition, perception and action. This coupling, together with a prominent role of prediction in music processing, fits well with recently described ideas about the role of predictive processing in cognitive function, which appears to be especially suitable to account for the role of mental models in musical perception and action. Investigating the cerebral correlates of constructive music imagination offers an experimentally tractable approach to clarifying how mental models of music are represented in the brain. I suggest here that mental representations underlying imagery are multimodal, informed and modulated by the body and its in- and outputs, while perception and action are informed and modulated by predictions based on mental models

On Orbital Period Changes in Nova Outbursts

We propose a new mechanism that produces an orbital period change during a nova outburst. When the ejected material carries away the specific angular momentum of the white dwarf, the orbital period increases. A magnetic field on the surface of the secondary star forces a fraction of the ejected material to corotate with the star, and hence the binary system. The ejected material thus takes angular momentum from the binary orbit and the orbital period decreases. We show that for sufficiently strong magnetic fields on the surface of the secondary star, the total change to the orbital period could even be negative during a nova outburst, contrary to previous expectations. Accurate determinations of pre- and post-outburst orbital periods of recurrent nova systems could test the new mechanism, in addition to providing meaningful constraints on otherwise difficult to measure physical quantities. We apply our mechanism to outbursts of the recurrent nova U Sco.Comment: Accepted for publication in MNRA
