The Singing Insects of Michigan

Excerpt: The so-called singing insects are all those that make loud, rhythmical noises. They include members of three groups of Orthoptera (Gryllidae, Tettigoniidae, and Acridoidea) and one family of Homoptera (Cicadidae). There are about 300 noisy species in these four groups in eastern North America, perhaps a thousand in all of North America, and 25-30 thousand in the entire world. Only about 1000 of the world species have been studied in any detail, mostly in North America, Europe, Japan, and Australia

Range-dependent flexibility in the acoustic field of view of echolocating porpoises (Phocoena phocoena)

Funding: Det Frie Forskningsrad (MJ)Toothed whales use sonar to detect, locate, and track prey. They adjust emitted sound intensity, auditory sensitivity and click rate to target range, and terminate prey pursuits with high-repetition-rate, low-intensity buzzes. However, their narrow acoustic field of view (FOV) is considered stable throughout target approach, which could facilitate prey escape at close-range. Here we show that, like some bats, harbour porpoises can broaden their biosonar beam during the terminal phase of attack but, unlike bats, maintain the ability to change beamwidth within this phase. Based on video, MRI, and acoustic-tag recordings, we propose this flexibility is modulated by the melon and implemented to accommodate dynamic spatial relationships with prey and acoustic complexity of surroundings. Despite independent evolution and different means of sound generation and transmission, whales and bats adaptively change their FOV, suggesting that beamwidth flexibility has been an important driver in the evolution of echolocation for prey tracking.Publisher PDFPeer reviewe

Early interpersonal trauma reduces temporoparietal junction activity during spontaneous mentalising

Experience of interpersonal trauma and violence alters self-other distinction and mentalising abilities (also known as theory of mind, or ToM), yet little is known about their neural correlates. This fMRI study assessed temporoparietal junction (TPJ) activation, an area strongly implicated in interpersonal processing, during spontaneous mentalising in 35 adult women with histories of childhood physical, sexual, and/or emotional abuse (childhood abuse; CA) and 31 women without such experiences (unaffected comparisons; UC). Participants watched movies during which an agent formed true or false beliefs about the location of a ball, while participants always knew the true location of the ball. As hypothesised, right TPJ activation was greater for UCs compared to CAs for false vs true belief conditions. In addition, CAs showed increased functional connectivity relative to UCs between the rTPJ and dorsomedial prefrontal cortex. Finally, the agent’s belief about the presence of the ball influenced participants’ responses (ToM index), but without group differences. These findings highlight that experiencing early interpersonal trauma can alter brain areas involved in the neural processing of ToM and perspective-taking during adulthood

‘From Badness to Sickness’ and Back Again: The Use of Medication in the U.S. School and Foster Care Systems

This article explores the over- and under-prescription of psychotropic medication to youth of color both in public schools and the foster care system. Under the umbrella of the schools-to-prison pipeline, there is a wide array of literature addressing the under-use of medication for treatment of children of color in the public school system when treating learning or behavioral disabilities. There is also, however, a great deal of literature in a totally different realm surrounding the under-use of medication in treating mental health disorders in the foster care system. This article aims to put these two pieces of discourse in conversation with each other. In examining the use of medication in both of these institutions and the disproportionate rate of black and brown children in the foster care system, I analyze how race, class, and gender play a role in the prescription—or lack thereof—of medication for children of color. These contradicting approaches to treatment and medication illustrate the assumptions that are attached to children of color, and how these institutions ultimately were not made for children of color to survive or thrive. To better serve the needs of children in our country, these two institutions must be considered as co-actors in the system of perpetual social control exerted of youth of color

Peeling Back the Student Privacy Pledge

Education software is a multi-billion dollar industry that is rapidly growing. The federal government has encouraged this growth through a series of initiatives that reward schools for tracking and aggregating student data. Amid this increasingly digitized education landscape, parents and educators have begun to raise concerns about the scope and security of student data collection. Industry players, rather than policymakers, have so far led efforts to protect student data. Central to these efforts is the Student Privacy Pledge, a set of standards that providers of digital education services have voluntarily adopted. By many accounts, the Pledge has been a success. Since its introduction in 2014, over 300 companies have signed on, indicating widespread commitment to the Pledge’s seemingly broad protections for student privacy. This industry participation is encouraging, but the Pledge does not contain any meaningful oversight or enforcement provisions. This Article analyzes whether signatory companies are actually complying with the Pledge rather than just paying lip service to its goals. By looking to the privacy policies and terms of service of a sample of the Pledge’s signatories, I conclude that noncompliance may be a significant and prevalent issue. Consumers of education software have some power to hold signatories accountable, but their oversight abilities are limited. This Article argues that the federal government, specifically the Federal Trade Commission, is best positioned to enforce compliance with the Pledge and should hold Pledge signatories to their promises

Are Prize-Linked Savings Accounts the Solution to Arkansas\u27 Savings Problem?

This research finds that access to prize-linked savings could improve the financial security of Arkansans. Prize-linked savings (PLS) accounts are nontraditional savings products that offer depositors the chance to win cash prizes instead of a typical interest rate return. Given the low median incomes, high liquid asset poverty rates, and high levels of underbanked and undereducated individuals in Arkansas, there is a need for an innovative savings solution like PLS in the state. PLS accounts capitalize on individuals’ propensity for lottery-like risk-taking to inspire the productive behavior of personal saving. A wide range of individuals, especially those who could stand to benefit from PLS instruments the most, find these programs attractive. Various PLS programs have proven successful internationally and within the United States, with clear benefits for both savers and organizing financial institutions. Arkansas banks and credit unions should consider the opportunity presented by PLS programs to grow deposits while providing Arkansas households with an effective, entertaining way to increase personal savings and strengthen their financial situation
