From Other-Direction to the Me Decade: The Development of Fluid Identities and Personal Role Definitions*

A comparison of the basic traits of American character in the 1950s and the 1970s suggests that the narcissism of the 1970s is continuous with the other-direction of the 1950s, except that the narcissist makes a virtue out of what the other-directed person saw as problematic. The narcissist accommodates himself more fully to a social structure that demands great personal flexibility. He thus adopts a fluid identity and personal role definitions. Suggestive evidence of such identity change is found in the self-help literature of 1940 to 1979.     

Integrating Health and Social Care at the Micro Level: Health Care Professionals as Care Managers for Older People

A common problem in the provision of coordinated long‐term care is the separation of health and social care. The present government has been increasingly concerned with promoting convenient, user‐centred services and improving integration of health and social care. One arrangement that could contribute to this for some older service users is for health care staff to act as care managers, coordinating the provision of both health and social care. This paper presents the findings of a survey of arrangements in place in local authorities for health staff to work as care managers for older people. This was designed to provide details about the range and scope of care management activities undertaken by health care professionals. Key areas of enquiry included: which kinds of health care staff undertook care management and in what settings; how long the arrangements had been in place and how widely available they were; whether there was a distinction between the types of cases and care management processes undertaken by health care staff compared with their social service department counterparts; and what management and training arrangements were in place for the health care staff.     

Citizenship Lessons from the Past: The Contours of Immigrant Naturalization in the Early 20th Century*

Objectives. What were the determinants and patterns of naturalization in the first two decades of the 20th century? Low levels of citizenship acquisition among contemporary immigrants are frequently contrasted to the assumed rapid naturalization of prior European migrants, but in truth we know little about the earlier period. Historic data are well suited to investigate four explanations for naturalization: individuals' resources and skills; regulatory and bureaucratic barriers to citizenship; relative costs and benefits of citizenship; and the degree of political mobilization directed to immigrants. Methods. I use U.S. Census microfile data to run logistic regression models, and documentary material to examine the contours of immigrant naturalization in the early 20th century. Results. I find that while individual attributes matter, place of residence could be even more important; in 1900, where an immigrant lived influenced naturalization more than birthplace, ability to speak English, or literacy. Residence effects seem linked to a state's relative openness to immigration and local political mobilization. Over time, however, residence effects attenuate as the 1906 Naturalization Act and establishment of a federal naturalization bureaucracy appear to make citizenship patterns more uniform across the country. Conclusions. These findings suggest that historic and contemporary explanations of immigrants' naturalization should focus as much on the context of reception as the presumed quality of immigrants.     

Client Evaluations of Therapeutic Processes and Outcomes in a University Mental Health Center

Abstract

Evaluations of therapeutic processes and outcomes by clients, therapists, and independent third parties are all important dimensions in an overall system of accountability for a college mental health facility. This study focused on client evaluation. All clients (N = 287) who used mental health services in a large midwestern university during a two-week period completed an evaluative questionnaire. In contrast to previous satisfaction studies that focused on overall satisfaction, this study examined specific therapist and client tasks and their relationship to outcomes. The findings indicate that different types of client evaluation items yield somewhat different results. Those specific evaluation items have varying relationships with overall measures of client satisfaction and problem improvement. The study also pointed to the importance of looking at sex differences in client evaluations of therapy and at differences among therapists in their relative success in working with clients with differing problems.

“The Diagnosis of Testicular Torsion,” Bruce E. Haynes, Howard A. Bessen, and Vital E. Haynes. Prompt diagnosis of testicular torsion remains difficult. Since warning symptoms occur in one third of patients and salvage rates correspond to the interval between symptom onset and operation, higher salvage rates should be achievable. Separating torsion from epididymitis is complicated by overlapping ages of peak incidence, shared symptoms, and the need for rapid distinction of the two. Doppler studies (88% accuracy) and nuclear scans (95% accuracy) help confirm the diagnosis, but correct technique is essential, and their use should not delay prompt operation. The diagnosis of epididymitis should be made cautiously in persons younger than the age of 35 years. (Journal of the American Medical Association 1983;249:2522–2527.)

“Hepatitis and Jaundice Associated with Measles in Young Adults: An Analysis of 65 Cases,” Dov Gavish, Yosef Kleinman, Abraham Morag, Tova Chajek-Shaul. We analyzed the clinical course of 65 adult patients hospitalized because of measles during the years 1975 and 1981–1982. Liver involvement was found in 80% (52/65) of the patients, five patients had clinical jaundice. The disturbances of liver function tests reached their peak values between days 5 and 10 of the disease. In this study of measles in adulthood we have three observations of unusual interest: (1) hepatitis occurs commonly in the more severely ill patients and it may manifest clinically as jaundice; (2) long-term follow-up (up to seven years) shows a clear tendency to complete resolution of the liver damage; (3) there is a clear correlation between the severity of hepatic involvement and the occurrence of secondary bacterial infections.
