let  be a banach algebra. let  be linear mappings on . first we demonstrate a theorem concerning the continuity of double derivations; especially that all of -double derivations are continuous on semi-simple banach algebras, in certain case. afterwards we define a new vocabulary called “-higher double derivation” and present a relation between this subject and derivations and finally give some ...

Purpose – Drawing from the literature, the purpose of this paper is to offer an empirically validated framework for examining information technology (IT) readiness in small firms. Design/methodology/approach – A conceptual framework of IT readiness for small firms is developed and validated empirically using a quantitative survey of 117 UK manufacturing small firms to identify distinct clusters...

The objective of this study was to investigate the effects of varying doses of caffeine on memory impairment and the expression of brain neurotrophic derived factor (BNDF) and TrkB in PS1/APP double transgenic mouse models. PS1/APP double transgenic mice were administered 0.3 ml/day of saline, 1.5 mg/day of caffeine or 0.75 mg/day of caffeine for eight weeks. A water maze test and western blott...

Drawing on the Job Demand-Resources (JD-R) theory, present study investigates underlying mechanisms through which capability control, a type of behavior-based influences salesperson turnover. Using sample 145 industrial salesperson–supervisor dyads from different industries, this study's findings reveal that control contributes to decreasing turnover intentions, both directly and indirectly. Sp...
