Experiments exploring the effects of group discussion on attitudes, jury decisions, ethical decisions, judgments, person perceptions, negotiations, and risk taking (other than the choice-dilemmas task) are generally consistent with a "group polarization" hypothesis, derived from the risky-shift literature. Recent attempts to explain the phenomenon fall mostly into one of three theoretical appro...

Optical and near-IR observations of the halos of disk galaxies and blue compact galaxies have revealed a very red spectral energy distribution which cannot easily be reconciled with a normal, metal-poor stellar population like that in the stellar halo of the Milky Way. Here, spectral evolutionary models are used to explore the consequences of these observations. We demonstrate that a stellar po...

A 26-year-old woman was referred to us because of her hypertension and microscopic haematuria. Her past medical and family histories were unremarkable and the physical examination was not contributory. The urinary analysis revealed numerous red blood cells without dysmorphic changes. The laboratory tests revealed haemoglobin 13.6 g/dl, haematocrit 39%, white blood cell count 4300/mm, blood urea...

The Principle of the Glitch states that for any device which makes a discrete decision based upon a continuous range of possible inputs, there are inputs for which it will take arbitrarily long to reach a decision. The appropriate mathematical setting for studying this principle is described. This involves defining the concept of continuity for mappings on sets of functions. It can then be show...

The Oklo Phenomenon is a solo dance piece controlling sound and light with movement. The performer(s) uses eye movement, facial gesture and body movement to control stage lighting and sound. The synergistic effect of all three of these media — movement, light and sound — generates a unique relationship between the performer and his surroundings as they become both an outside force with which he...

A 57-year-old man presented with new anginal symptoms nine years after three-vessel coronary artery bypass grafting. Cardiac catherization revealed severely and diffusely diseased saphenous vein graft to the obtuse marginal coronary artery. Percutaneous coronary intervention was complicated by the ‘no-reflow’ phenomenon. The patient suffered a periprocedural myocardial infarction (peak troponin...

The Lazarus phenomenon or the unassisted return of spontaneous circulation after cardiac arrest is a grossly underreported phenomenon in medical literature which essentially implies the 'resurrection' of an individual after cardiac arrest. Although there have been a handful of such cases reported, the clinical incidence and significance may be underestimated. Because of the presumed infrequency...

If asked whether certain digits in numbers collected randomly from, for example, the front pages of newspapers or from stock-market prices should occur more often than others, most people would think not. Nonetheless, in 1881, the astronomer and mathematician Simon Newcomb published a two-page article in the American Journal of Mathematics reporting an example of exactly that pheonomenon. Newco...

The cyclic sieving phenomenon is defined for generating functions of a set affording a cyclic group action, generalizing Stembridge’s q 1⁄4 1 phenomenon. The phenomenon is shown to appear in various situations, involving q-binomial coefficients, Pólya–Redfield theory, polygon dissections, noncrossing partitions, finite reflection groups, and some finite field q-analogues. r 2004 Elsevier Inc.

This paper reviews theory and research regarding the ‘‘Michelangelo phenomenon.’’ The Michelangelomodel suggests that close partners sculpt one another’s selves, shaping one another’s skills and traits and promoting versus inhibiting one another’s goal pursuits. As a result of the manner in which partners perceive and behave toward one another, each person enjoys greater or lesser success at at...
