A Suicide Prevention Campaign for Firearm Dealers in New Hampshire

A spate of suicides involving a just‐purchased firearm led a statewide coalition of firearm dealers, firearm rights advocates, and suicide prevention professionals to discuss the role of gun shops in preventing suicide. The group developed and mailed materials for (1) firearm retailers on avoiding sales to suicidal customers and (2) their customers on suicide and firearm safety. All storefront retailers were identified (n = 65), visited unannounced 6 months after receiving materials, and asked to complete a survey. Nearly half (48%) had at least one campaign product on display. Belief that reducing a suicidal person's access to firearms might save a life was associated with displaying materials (69% vs. 41%, p = .06). Public health and gun groups can successfully collaborate on suicide prevention activities.     

A normal approximation for testing the equality of two independent Chi-square variables

A simple normal approximation is supplied to test the equality of two independent Chi-square variables. The approximation appears to be valid for degrees of freedom as small as two. Thus no new table of critical values is needed. The standard unit normal distribution tables are sufficient.     

The Shellen chart as a test of visual acuity

Summary An analysis of the mistakes made by 100 boys in reading the letters on a Snellen Chart reveals great differences in legibility between letters of the same size. This is found to depend on the shape and familiarity of the letter and its similarity to other letters. Whether a test of visual acuity consists of two-point discrimination or the perception of meaningful shapes, mental organization is a deciding factor in determining the response. While oculists are interested in the part played by the eye in vision, psychologists direct attention to the part played by the mind.Based on a paper read at the British Association Meeting at Newcastle in September, 1949.     

A political economy of the Poor People’s Campaign: From MLK and Polanyi to Trump

ABSTRACT

A stalemate has emerged in mainstream liberal/left responses to Trump. Many commentators prefer to see our predicament in terms of either class-based or identity politics. Vis-à-vis the influence of the Chicago school of economics and its structural adjustment schemes, we crosshatch MLK’s Poor People’s Campaign and Polanyi’s Great Transformation to envision overcoming this stalemate. King’s effort to radicalize the welfare state from below by linking struggles against poverty, racism, and imperialism shares Polanyi’s focus on the economy’s embeddedness in society. We underscore the importance of King’s and Polanyi’s visions for building a leftist coalition that does not divorce social from economic justice.     

Identification of Nearly Fatal Suicide Attempts: Self-Inflicted Injury Severity Form

The Self-inflicted Injury Severity Form (SIISF) was developed as an epidemiological research tool for identifying individuals in hospital emergency departments who have life-threatening self-inflicted injuries. Data were collected from 715 patients with self-inflicted injuries in two large hospitals. In 295 of these cases, a second set of data was independently collected for assessment of interrater reliability. Validity was assessed by comparing the SIISF results with simultaneously collected Risk—Rescue Ratings. Assessment of interrater reliability found that only 2.4% of physicians disagreed on the suicide method used. The kappa statistic for method used was .94, indicating excellent agreement. The SIISF was found to distinguish between severe and less severe injuries. Thus, it appears to provide a simple method to distinguish patients who have life-threatening self-inflicted injuries.
