What explains the truth of a universal generalization? Two types explanation can be distinguished. While an ‘instance-based explanation’ proceeds via some or all instances generalization, ‘generic is independent instances, relying instead on completely general facts about properties operations involved in generalization. This intuitive distinction analyzed by means truthmaker semantics, which a...

Two deletion-substitution mutations of phage lambda, spi-113 and spi-274, are shown to remove about half of the rightward operator OR. Physiological studies show that spi-113 is still repressible. Thus, the 50 or so nucleotides of OR deleted in this mutant are not absolutely essential for repression. prm-116, which inactivates the promoter essential for the maintenance of lambda repressor synth...

Vaccinia DNA topoisomerase binds duplex DNA and forms a covalent adduct at sites containing a conserved sequence element 5'(C/T)CCTT decreases in the scissile strand. Distinctive aspects of noncovalent versus covalent interaction emerge from analysis of the binding properties of Topo(Phe-274), a mutated protein which is unable to cleave DNA, but which binds DNA noncovalently. Whereas DNA cleava...

Despite the growing research on financial resources within supply chain of SMEs, our understanding relationship between resource building efforts and availability remains lacking. This study draws attention-based view theory (ABV) to develop test an argument that heterogeneity in is explained by differences SMEs effort. The proposed tested a sample 274 owners Ghana.
