Husbands who harm: Predicting spousal violence by men

Previous research on spouse abuse has frequently focused on bivariate relationships between theoretically derived variables and marital violence. This study utilizes a multivariate approach in order to explore the independent and combined effects of several variables derived from the social learning and the frustration/strain perspectives on self-reported violence by husbands against wives. Data for married and/or cohabiting males are derived from a national stratified random sample of couples in the United States. Loglinear analysis is used to identify the main and interactive effects of age, occupational status, employment status, subjective economic strain, and observation of parental violence on reports of violence toward one's wife. Results indicate that age, occupational status, parental modeling and employment status affect the likelihood of violence. Employment status more strongly increases the likelihood of violence for younger men, as opposed to older men, which supports the strain perspective. The independent effect of the observation of parental violence lends support to the social learning approach. Social policy implications are discussed.     

Attributions for fair exchange outcomes: The effects of power and status

This study focuses on how two fundamental social factors, structural power position and social status, affect attributions for relatively common, non-problematic exchange outcomes. We argue that the relative power and statuses of dyad members activate expectations of competence which in turn shape attributions in the situation. Subjects assumed the role of a typist described in a vignette of a transaction between a typist and a student needing a paper typed. We manipulated power positions in the vignette by varying the value and availability of the resource each actor desired; subject's sex and that of the fictive student represented social statuses. Despite the typicality of the exchange situation, results indicated that status and, to some extent power, created variation in the strength of attributions for the exchange outcome. Females, presumably expected to be more competent typists, made stronger self-attributions for the typing payment than males. Similarly, those in high power positions tended to attribute the payment more to themselves than occupants of low power positions.     

Cor triatriatum sinistrum: a rare congenital cardiac anomaly presenting in an adult with chronic atrial fibrillation

Cor triatriatum is a rare congenital cardiac anomaly in which the left atrium is divided into proximal (dorsal or upper) and distal (ventral or lower) chambers by a fibromuscular septum. The upper chamber receives the pulmonary veins and the lower chamber contains the atrial appendage and the mitral valve. The 2 chambers communicate through a defect in the membrane. Cor triatriatum is often associated with other congenital cardiac anomalies. Most frequently, the upper chamber communicates with the right atrium through a patent foramen ovale or atrial septal defect, and the clinical symptoms simulate anomalous pulmonary venous return. Less commonly, the foramen ovale communicates with the distal chamber and the clinical features mimic mitral stenosis. When cor triatriatum is the only abnormality, the clinical findings are also similar to mitral stenosis with development of pulmonary hypertension and subsequent right ventricular hypertrophy and atrial enlargement. The diagnosis is usually made in infancy or childhood, and the lack of treatment results in death in 75% of patients.We report the case of a woman who presented much later in life. The patient was a 57-year-old female with a clinical history of chronic atrial fibrillation who presented to the emergency department because of a "funny sensation" in her chest, though she denied chest pain, nausea, vomiting, or diaphoresis. EKG revealed atrial fibrillation with a rapid ventricular response and a tachycardic rate of 157. She had a therapeutic level of digoxin, and cardiac enzymes were normal. The patient was admitted and placed on Cardizem drip. Serial EKGs remained normal and heart rate control was achieved. On hospital day 2, the patient became dyspneic and cyanotic. She went into cardiac arrest and died.Autopsy revealed cardiomegaly (610 g) with 4-chamber dilatation. A septum divided the left atrium into 2 chambers. The defect in the dividing membrane measured 1 cm in diameter. No other congenital defects were noted. The large size of the defect in the membrane likely accounted for the late onset of symptoms that allowed this patient to survive into adulthood without previous diagnosis or surgical intervention (which is usually required in childhood).
