Positivity: The Dispositional Basis of Happiness
Journal of Happiness Studies, 2016The present study examined in a stringent developmental model whether positivity, conceptualized as a pervasive mode of appraising, viewing, and perceiving life from a positive stance, predicts chronic positive affectivity across time or vice versa. Participants [263 participants (47 % males)], aged 15.5 at the beginning of the study and 23.5 at the ...

The molecular basis of positional signalling: introduction
Development, 1989ABSTRACT The importance of cell–cell interactions in embryonic development was first described by Driesch (1891), who showed that any of the blastomeres of the 2-cell or 4-cell sea-urchin embryo is capable of forming a complete embryo if cultured in isolation; this implied that in normal development each blastomere is aware of the other ...

Invariant Subspaces for Positive Operators Acting on a Banach Space with Markushevich Basis
Positivity, 2004 We introduce 'weak quasinilpotence' for operators. Then, by substituting 'Markushevich basis' and 'weak quasinilpotence at a nonzero vector' for 'Schauder basis' and 'quasinilpotence at a nonzero vector', respectively, we answer a question on the ...

A structural basis for variegating position effects
Cell, 1984Variegating position effects in Drosophila result from chromosome rearrangements where normal genes, having been placed next to heterochromatin, are inactivated in some cells but not in others, thereby producing a variegated tissue. We have determined that the euchromatic breakpoints for three variegating white mutants are clustered and lie ...

Natural head position as a basis for cephalometric analysis
American Journal of Orthodontics and Dentofacial Orthopedics, 1992In a sample of orthodontic patients (27 boys and 25 girls, 10 to 14 years old), natural head position (NHP) was photographically recorded. A vertical axis was recorded on the photographs with a plumb line and transferred to the lateral head radiographs of the patients.

Basis of false-positive glucagon tests for pheochromocytoma
Clinical Pharmacology and Therapeutics, 1981In more than half of 67 patients suspected of having pheochromocytoma, glucagon stimulation increased plasma free norepinephrine (NE) and epinephrine (E) 50% or more, with rising blood pressure or pulse rate; only three patients, however, harbored a pheochromocytoma.

Structural basis for the positional specificity of lipoxygenases
Prostaglandins & Other Lipid Mediators, 2000The positional specificity of arachidonic acid oxygenation is currently the decisive parameter for classification of mammalian lipoxygenases but, unfortunately, the structural reasons for lipoxygenase specificity are not well understood. Although there are no direct structural data on lipoxygenase/substrate interaction, experiments with modified fatty ...

The vascular basis of the positional influence on the intraocular pressure
Albrecht von Graefes Archiv f�r Klinische und Experimentelle Ophthalmologie, 1978By measuring intraocular pressure in different body positions from 60 degrees semiupright to 30 degrees head down, a nonlinear relationship between IOP increase and body position was confirmed. IOP postural response in individual subjects was roughly correlated to ophthalmic arterial pressure and to the episcleral venous pressure postural response.

Statistical basis for positive identification in forensic anthropology
American Journal of Physical Anthropology, 2006Forensic scientists are often expected to present the likelihood of DNA identifications in US courts based on comparative population data, yet forensic anthropologists tend not to quantify the strength of an osteological identification. Because forensic anthropologists are trained first and foremost as physical anthropologists, they emphasize ...
