Time period and birth cohort differences in depressive symptoms in the U.S. | Jean M. Twenge

Jean M. Twenge; Time Period and Birth Cohort Differences in Depressive Symptoms in the U.S., 1982–2013; In Social Indicators Research; 2015-04; 36 pages; draft; paywall.


Across four surveys (N = 6.9 million), Americans reported substantially higher levels of depressive symptoms, particularly somatic symptoms, in the 2000s–2010s compared to the 1980s–1990s. High school students in the 2010s (vs. the 1980s) reported more somatic symptoms (e.g., trouble sleeping, thinking, and remembering; shortness of breath) and were twice as likely to have seen a professional for mental issues. College students in recent years (vs. the 1980s) were more likely to report feeling overwhelmed and to believe they were below average in mental and physical health, but were less likely to say they felt depressed. Total Center for Epidemiological Studies Depression scores were higher among adults in 2000 (vs. 1988), especially somatic symptoms. Teens displayed less suicidal ideation in 2011 versus 1991 and were slightly less likely to commit suicide. Thus, more subtle symptoms of depression became more prevalent even as some overt indicators of depression became less prevalent.

The Decline of Play and the Rise of Psychopathology in Children and Adolescents | Peter Gray

Peter Gray; The Decline of Play and the Rise of Psychopathology in Children and Adolescents; In American Journal of Play; Volume 3, Number 4; Spring, 2011; 21 pages.


Over the past half century, in the United States and other developed nations, children’s free play with other children has declined sharply. Over the same period, anxiety, depression, suicide, feelings of helplessness, and narcissism have increased sharply in children, adolescents, and young adults. This article documents these historical changes and contends that the decline in play has contributed to the rise in the psychopathology of young people. Play functions as the major means by which children

  1. develop intrinsic interests and competencies;
  2. learn how to make decisions, solve problems, exert self-control, and follow rules;
  3. learn to regulate their emotions;
  4. make friends and learn to get along with others as equals; and
  5. experience joy.

Through all of these effects, play promotes mental health.

Key words: anxiety; decline of play; depression; feelings of helplessness; free play; narcissism; psychopathology in children; suicide


  • <quote>Clinicians know for certain that anxiety and depression correlate strongly with individuals’ sense of control or lack of control over their own lives.</quote>

Decimeter-Level Localization with a Single WiFi Access Point | Vasisht, Kumar, Katabi

We present Chronos, a system that enables a single WiFi access point to localize clients to within tens of centimeters. Such a system can bring indoor position- ing to homes and small businesses which typically have a single access point.

The key enabler underlying Chronos is a novel algorithm that can compute sub-nanosecond time-of-flight using commodity WiFi cards. By multiplying the time-of-flight with the speed of light, a MIMO access point computes the distance between each of its antennas and the client, hence localizing it. Our implementation on commodity WiFi cards demonstrates that Chronos’s accuracy is comparable to state-of-the-art localization systems, which use four or five access points.
