On the citation influence methodology of Pinski and Narin

Using Markov Chain theory we give further insight into the citation influence methodology for scientific publications which was initially described by Pinski and Narin.     

Experiential education from a cultural viewpoint: The peer evaluation meeting as a ritual of enculturation

Experiential education may be viewed as a process of enculturation; a student explores the work culture in depth and learns how to develop the personality characteristics prized by the culture. Implications of a cultural viewpoint for selection, training, and evaluation of students in an undergraduate internship in a psychiatric residential treatment center for adolescents are examined. One ritual of enculturation, the peer evaluation meeting, is discussed and recommended for its benefits to experiential education as a tool for training, providing staff identity and psychological support, and affirmation of the values of the institution.     

Modulation of an activity response with associative and nonassociative fear in the rat: A lighting differential influences the form of defensive behavior evoked after fear conditioning

Rats confronted with the onset of a light gradient display a transient increase in locomotion called theactivity response (AR) and a dark preference (Godsil & Fanselow, 2004). These experiments demonstrate that the magnitude of the AR can be blunted with Pavlovian fear-conditioning procedures via associative and nonassociative fear. Although manifested in decreased locomotion, the blunted AR effect was not due to increased freezing or immobility behaviors. Instead, rats displayed reduced rearing and an increase in a class of behaviors calledstationary activity. These results suggest that the lighting differential supplied by the cue influences the topography of defensive behavior and reduces the expression of freezing. This procedure provides a means by which to examine learned and unlearned defensive responses to the same stimulus.     

Modification of attitudes of regular class children towards the handicapped for the purpose of achieving integration

Two experimental procedures for positively modifying the attitudes of regular classroom children towards the handicapped were conducted. In both studies, curriculum and/or experiences with the handicapped were introduced to randomly selected groups of regular class elementary children. The curriculum consisted of literature, filmstrips, and lectures about handicapped children, while the experiences consisted of controlled integrational activities. The results indicated that the procedures were partially successful in modifying the attitudes of regular class children towards the handicapped. It was concluded that techniques must be developed systematically for achieving more positive attitudes in regular class children if “mainstreaming” is to become an effective educational concept.     

Study of C-Reactive Protein and Myocardial Infarction in the Indian Population

To analyse the association of high sensitivity C-reactive (hsCRP) protein levels and −717A/G single nucleotide polymorphism of CRP with acute myocardial infarction (AMI) in the Indian population. Study population included 100 MI cases wherein 32 patients had experienced previous MI (MI-Group-1), 68 MI cases were recruited at presentation (MI-Group-2) and equal number of age and gender matched healthy individuals. hsCRP levels were determined by ELISA and genotyping of −717A/G was carried out by polymerase chain reaction-based restriction digestion method. The −717A/G genotypes did not influence hsCRP level and their distribution did not differ between groups. However, in the present study hsCRP demonstrated significant correlation with BMI in controls of both the genders and with triglycerides in females of AMI at presentation who otherwise are with low risk profile. Identifying traditional risk factors associated with inflammation may help in controlling the acute event.     

A Comparative Study of Bone Scan Findings and Serum Levels of Tumor Marker CA15-3 in Patients with Breast Carcinoma

Breast cancer is one of the most frequent malignancies in the world. Available staging procedures to detect breast cancer are bone scan, chest X-ray, liver ultrasonography, computerized tomography, estimation of tumor markers like carbohydrate antigen (CA15-3) and carcino embryonic antigen. These procedures are expensive and may not be required in all cases. Out of 70 patients studied, 55 had normal CA15-3 and 15 had elevated levels of Ca15-3. Eight (14.5%) of the 55 patients with normal CA15-3 had abnormal bone scan. Fifteen patients had CA15-3 levels above the normal range and among these 9 (60%) had abnormal bone scan. While prime facie it would appear that a high level of CA15-3 correlate with abnormal bone scan, it is also true that the numbers are small at present and conclusions about the validity of CA15-3 as marker of bone metastasis may be premature.
