A day at a time: Predicting smoking lapse from daily urge.

Smokers who recently quit (N?=?214) monitored smoking urges for up to 26 days after quitting. Computers administered 4–5 assessments daily at random times; participants rated urges on waking and when they experienced temptation episodes. Urge intensity after cessation did not generally exceed urges reported during baseline ad lib smoking. Urge intensity and temptation frequency consistently declined over the quit period. Controlling for urge intensity at baseline, all daily urge intensity measures predicted lapse the following day in proportional hazards survival analyses. Average duration of temptation episodes also predicted lapses; frequency of temptation did not. To isolate the effect of day-to-day variations in urges, participants' nicotine dependence and urge intensity on quit day were controlled for. Only urge intensity at waking still predicted lapse risk; this was not because of this measure being closer in time to the day's lapses. Among lapsers, urge intensity at waking and in temptations rose preceding a lapse. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The War of the Well(e)s

A metaliterary analysis of Welles' famous radio broadcast explores "the conditions in which fact and fiction can be confused, and …the power of the mass media to exploit those conditions."     

The relationship of hostility to authoritarianism.

A manifest hostility scale, consisting of items drawn from the MMPI, and the Elizur Rorschach Content Test were given to groups differing in degree of authoritarianism. Statistical analysis of the relationship between the manifest hostility scale and authoritarianism indicated that groups high on the dimension of authoritarianism have greater overt hostility than groups lower on this dimension. Results relevant to the relationship between the Rorschach Content Test and authoritarianism indicated a less certain tendency for groups low on the dimension of authoritarianism to have greater covert hostility than groups higher on this dimension.

Ontogeny of meal patterning in rats and its recapitulation during recovery from lateral hypothalamic lesions.

Investigated the development of feeding patterns in weanling rats and in rats with lateral hypothalamic lesions. 2 experiments were conducted with a total of 39 male albino Sprague-Dawley rats. From 16 to 25 days of age, the weanlings demonstrated a preprandial intake pattern (i.e., a positive correlation between meal size and time since the preceding meal). This subsequently declined while the postprandial relationship (correlation with time until subsequent meal) such that by 30-35 days of age a full adult pattern was observed. Ss recovering from lateral hypothalamic lesions, for a brief period, also demonstrated a preprandial intake pattern. The postprandial relationship was abolished by the lesion. Results suggest that the development of adult meal patterning results from maturation of lateral hypothalamic mechanisms governing meal initiation.

The cost of caring for end-stage kidney disease patients: an analysis based on hospital financial transaction records

The costs of care for end-stage renal disease patients continue to rise because of increased numbers of patients. Efforts to contain these costs have focused on the development of capitated payment schemes, in which all costs for the care of these patients are covered in a single payment. To determine the effect of a capitated reimbursement scheme on care of dialysis patients (both hemodialysis [HD] and peritoneal dialysis [PD]), complete financial records (all reimbursements for inpatient and outpatient care, as well as physician collections) of dialysis patients at a single medical center over 1 year were analyzed. For the period from July 1994 to July 1995, annualized cost per dialysis patient-year averaged $63,340, or 9.8% higher than the corrected estimate from the U.S. Renal Data Service (USRDS; $57,660). The "most expensive" 25% of patients engendered 44 to 48% of the total costs, and inpatient costs accounted for 37 to 40% of total costs. Nearly half of the inpatient costs resulted from only two categories (room charges and inpatient dialysis), whereas other categories each made up a small fraction of the inpatient costs. PD patients were far less expensive to care for than HD patients, due to reduced hospital days and lower cost of outpatient dialysis. Care for a university-based dialysis population was only slightly more expensive than estimates predicted from the USRDS. These results validate the USRDS spending data and suggest that they can be used effectively for setting capitated rates. Efforts to control costs without sacrificing quality of care must center on reducing inpatient costs, particularly room charges and the cost of inpatient dialysis.
