Miss, Mrs., Ms., or none of the above.

Two experiments with 90 undergraduates and 160 high school seniors examined whether negativity would be apparent in Ss' expectations and evaluations of course offerings when no title or the titles "Miss," "Mrs.," "Ms.," or "Mr." were used with the instructor's name. When course content was nontechnical, women called by traditional titles were at a disadvantage in the popularity of the course and in the expectation of intellectual challenge. All courses taught by Ms. instructors were rated comparably to those taught by Mr. or No Title instructors. Only courses ascribed to Miss or Mrs. instructors were the object of more negative judgments. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Design of an interactive debugger for FORTRAN: MANTIS

MANTIS is a natural debugging facility for the FORTRAN language subsystem on the PDP-10. It was designed and implemented in an existing language subsystem in order to facilitate program preparation and debugging in the time sharing environment available on the PDP-10. Suitable debugging facilities should be included in the initial design of language subsystems. Language subsystems to run in time sharing operating systems should offer debugging facilities that exploit the interactive environment available to the user. This paper describes experience gained in designing and adding a useful interactive debugger to an existing FORTRAN subsystem. Objectives, implementation experience and system features are discussed and are related to the general problem of designing debuggers for language subsystems.     

The effects of propranolol HCl in hippocampal-lesioned rats

Experiments were conducted to determine the effects of propranolol administration in rats lesioned in the hippocampal area. Chronic oral administration of propranolol to intact rats produced a significant decrease in mean systolic blood pressure. No significant changes in blood pressure were produced with propranolol treatment in rats lesioned in the septal or anterior hypothalamic areas, whereas, in rats lesioned in the hippocampal area, a significant elevation of blood pressure was observed. These findings confirm previous results that suggest that the hypotensive effects observed with chronic propranolol administration are mediated via the hippocampus.     

The Unusual Phase-Transitions in Ruthenate–Cuprate Superconducting Ferromagnets

We have systematically investigated the magnetic, electrical, and structural properties of the high-purity superconducting ferromagnet RuSr₂GdCu₂O₈, in which superconductivity and significant ferromagnetism have been reported to coexist. Our results show that there may exist in this compound a novel superconducting state which is characterized by the absence of a bulk Meissner effect, the presence of negligible superconducting condensation energy, and the appearance of an unusually large effective penetration depth. Such a state appears to have a nonuniform filamentary structure existing in the less magnetic walls between the ferromagnetic domains or a fine-grain structure beset by ferromagnetic walls between antiferromagnetic domains, similar to the case of NdNi₂B₂C. These results are presented and contrasted with the recently reported Meissner effect in RuSr₂GdCu₂O₈ in terms of the various phase transition sequences predicted.     

When fit is fundamental: Performance evaluations and promotions of upper-level female and male managers.

Using archival organizational data, the authors examined relationships of gender and type of position (i.e., line or staff) to performance evaluations of 448 upper-level managers, and relationships of performance evaluations to promotions during the subsequent 2 years. Consistent with the idea that there is a greater perceived lack of fit between stereotypical attributes of women and requirements of line jobs than staff jobs, women in line jobs received lower performance ratings than women in staff jobs or men in either line or staff jobs. Moreover, promoted women had received higher performance ratings than promoted men and performance ratings were more strongly related to promotions for women than men, suggesting that women were held to stricter standards for promotion.

What I think you think of me: Women's reactions to being viewed as beneficiaries of preferential selection.

Undergraduate women (N?=?150) participated in 2 experimental studies designed to examine the effects of knowing that another believed they were beneficiaries of preferential selection. Results indicated that participants' awareness that the other viewed them as having been selected on the basis of gender rather than merit (a) prompted inferences that the other held negative expectations of their competence (Studies 1 and 2); (b) produced timid, performance-limiting task decisions as well as negative self-regard when they were uncertain about their task ability level (Studies 1 and 2); and (c) produced ambitious, performance-maximizing task decisions when they knew themselves to be high in task ability and also were motivated to make a good impression (Study 2). In addition, in both studies negative affect resulted from the participants' knowledge that the other viewed them as having been preferentially selected.

Assuming preferential selection when the admissions policy is unknown: The effects of gender rarity.

One hundred thirty-five undergraduates indicated the degree to which they believed gender played a role in the selection of an applicant for a graduate degree program. Both the gender composition of the cohort and the selection policy (explicitly merit-based, explicitly affirmative action, or ambiguous) were varied. Results indicated that preferential selection on the basis of gender was assumed when women were solos and explicit information about the selection policy was not provided and that these assumptions were as strong as when an affirmative action policy was explicitly stated. This did not occur when the female selectee was not a solo or when a male selectee was a solo. Evaluations of qualifications and prediction of success paralleled the preferential selection assumptions. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Heart transplant coronary artery disease detected by coronary angiography: a multiinstitutional study of preoperative donor and recipient risk factors. Cardiac Transplant Research Database

BACKGROUND: Controversy exists regarding donor and recipient factors that promote the development and progression of coronary artery disease after heart transplantation and the likelihood of coronary artery disease causing death or retransplantation. METHODS: To investigate this issue in a large cohort of patients, we analyzed 5963 postoperative angiograms performed in 2609 of the 3837 patients undergoing heart transplantation at 39 institutions between January 1990 and December 1994. Coronary artery disease was classified as mild, moderate, or severe on the basis of left main involvement, primary vessel stenoses, and branch stenoses. Coronary artery disease was considered severe if left main stenosis was > 70% or 2 or more primary vessels stenoses were > 70% or branch stenoses were > 70% in all 3 systems. RESULTS: By the end of 5 years after heart transplantation, coronary artery disease was present in 42% of the patients, mild in 27%, moderate in 8%, and severe in 7%. Coronary artery disease-related events (death or retransplantation) had an actuarial incidence of 7% at 5 years and occurred in 2 of 3 of the patients with development of angiographically severe coronary artery disease. By multivariable logistic analysis, risk factors for donor coronary artery disease included older donor age (P < .0001) and donor hypertension (P=.0002). By multivariable analysis in the hazard function domain, risk factors identified for the earlier onset of allograft coronary artery disease included older donor age (P < .0001 ), donor male sex (P=.0006), donor hypertension (P=.07), recipient male sex (P=.02), and recipient black race (P=.01). The actuarial incidence of severe coronary artery disease was 9% at 5 years. CONCLUSIONS: Angiographic coronary artery disease is very common after heart transplantation, occurring in approximately 42% of the patients by 5 years. Older donor age, donor hypertension, and male donor or recipient predict earlier onset of angiographic allograft coronary artery disease. Although severe angiographic allograft coronary artery disease occurs in only 7% of the patients at 5 years, its presence is highly predictive of subsequent coronary artery disease-related events or retransplantation.     

Emotional influences on spatial attention.

The relationships between the anterior-posterior and left-right regions of the brain have been characterized as mutually inhibitory. Whereas the left hemisphere attends to right proximal hemispace and is associated with positive emotions, the right hemisphere attends to left distal hemispace and is associated with negative emotions. Because of the excitatory and inhibitory influences between the left and right frontal and posterior regions of the brain, the expression of emotion will result in an ipsilateral attentional bias. Given these functional systems, we hypothesized that positive emotions would be associated with a bias for left distal hemispace and negative emotions would be associated with a bias for right proximal hemispace. We tested these hypotheses by having 138 undergraduate students place emotionally labeled pegs on a large board. Our results indicated that the positively labeled pegs were placed in left distal hemispace and the relative placement of negatively labeled pegs was rightward and proximally. Whereas numerous research investigations have examined how attention is biased for emotional stimuli, ours is the first investigation to provide evidence that emotions can bias attentional allocation.

Lower respiratory illness in infants and young children with cystic fibrosis: evaluation of treatment with intravenous hydrocortisone

The enzyme-linked immunosorbent assay (ELISA) using HLA class I molecules purified from pooled platelets has the potential to detect HLA antibodies with increased efficiency without sacrificing sensitivity or specificity. This test, which was originally developed in our institution, has been independently validated by recent studies and is now commercially available. We now present evidence of its usefulness as a routine HLA antibody screening test for renal transplant patients. A total of 515 patients were tested monthly by ELISA (13.9 tests/patient) and by antiglobulin-enhanced panel reactivity (6.3 tests/patient). In patients found to be unsensitized, the incidence of false-positive results was less for ELISA than for the panel studies. In patients who were highly sensitized, both tests performed equally well, whereas discordant results were registered mainly in cases of mild sensitization. Because 66% of our patients were not sensitized, the ELISA was effective in reducing the number of more involved tests aimed at characterizing the antibodies. These results provide a foundation to use the pooled platelet HLA ELISA on a routine basis for HLA antibody screening.
