Screening for risk of inpatient violence

A screening checklist for assessing the risk of violence at the time of psychiatric hospitalization was developed. Checklist items and a cutoff point for low versus high risk of violence were selected based on a previous study of statistical prediction of violence. Application of the checklist to a new sample of 338 patients admitted to a university-based inpatient unit revealed promising results in identifying patients who later displayed aggressive behavior in the hospital, as indicated by its positive predictive value (59.0%), negative predictive value (70.6%), sensitivity (57.2%), specificity (70.0%), total predictive value (65.4%), and likelihood ratio (1.97). The results suggest the potential value of incorporating actuarial methods in the evaluation of violence risk.Funded in part by Biomedical Research Support Grant Program grant No. SO7-RR05775 from the Division of Research Resources, National Institutes of Health.

Rectification at three: Impact on the Cuban economy

Since 1986, Cuba has been engaged in a national effort to redirect its polity and economy; this effort, spearheaded by President Castro, is generally known as the “rectification” campaign. Although occurring at roughly the same time as reforms in the Soviet Union and Eastern Europe, the Cuban process—which emphasizes dismantling market-oriented mechanisms and enhancing economic centralization—differs radically from the others. An impressionistic assessment of the economic effects of rectification after its first three years (focusing on the behavior of macroeconomic indicators and of the construction sector) suggests that rectification has not turned the Cuban economy around. Moreover, it is questionable that rectification could do so in the medium term, considering the reforms that are taking place in Cuba's main trading partners, the Soviet Union and Eastern Europe. Jorge F. Pérez-López is an international economist with the Bureau of International Labor Affairs, U.S. Department of Labor. This article presents only his personal views. He has written on different aspects of the Cuban economy, including economic growth, the sugar industry, international trade and energy balances. His book,Measuring Cuban Economic Performance, was published by the University of Texas Press in 1987.     

Participatory methodologies and the product development process: the experience of Mixtec craftswomen in Mexico

This paper presents a product development methodology for use with indigenous rural workers. It is based on the revival of cultural and social values, with a focus on the conservation of natural resources. Illustrated by the case of Mixtec craftswomen in Mexico, this paper shows how poor groups can improve their living conditions through innovation and the diversification of their products. The process combines techniques of product development based on marketing, with a participatory focus and continuous improvement, in order to develop a unique and high‐quality product that can be more successfully marketed. The craftswomen are now able to plan their production and can evaluate and commercialise their products.     

Finding of a bullet in the cervical column of a body hit by a train

This case is about the finding of a body of an unidentified male of approximately 70 years of age who was hit by a train. During the carrying out of the corresponding autopsy and after the radiological tests for posterior odontological identification, a foreign body of a cylindrical-cone shape, identical to that of a bullet, was found lodged between the first and second cervical vertebrae. During dissection of the neck, a bullet was found. When the ballistic test was carried out, it was ascertained that the bullet was from a cartridge of 7.92 by 57-mm Mauser caliber, manufactured in Spain in 1936. This ammunition corresponds to that used during the Civil War in Spain (1936-1939). After the identification of the body, it was proved that the bullet was the result of a war wound. However, the victim had been unaware of the existence of the bullet, which had remained in his body for 50 years.
