Compositional inversion symmetry breaking in ferroelectric perovskites
Cubic perovskite compounds of the form (A(1/3)A(')(1/3)A(")(1/3))BO3 and A(B(1/3)B(')(1/3)B(")(1/3))O3, in which the differentiated cations form an alternating series of monolayers, are studied using first-principles methods. Such compounds are representative of a possible new class of materials in which ferroelectricity is perturbed by compositional breaking of inversion symmetry. For isovalen...
متن کاملInnovation, Change and Rule-breaking
Competitive dynamics impact a firm’s necessity to adapt its capabilities permanently and to generate innovations continuously. Therefore, management practice claims for continuous change and the generation of substantial innovations. However, to a certain degree, change and innovation are associated with a break of a firm’s existing mode of operation. Routines and underlying rulesystems become ...
متن کاملExcuse Validation: A Study in Rule-Breaking
Can judging that an agent blamelessly broke a rule lead us to claim, paradoxically, that no rule was broken at all? Surprisingly, it can. Across seven experiments, we document and explain the phenomenon of excuse validation. We found when an agent blamelessly breaks a rule, it significantly distorts people’s description of the agent’s conduct. Roughly half of people deny that a rule was broken....
متن کاملBreaking a law: tuberculosis disobeys Styblo's rule.
doi:10.2471/BLT07.049510 In 1985, Karel Styblo derived one of the guiding rules of tuberculosis (TB) epidemiology. Bringing together data from 16 countries, he proposed that an annual incidence of 50 sputum-smearpositive TB cases in a population of 100 000 generates an annual risk of infection of 1%.1 This rule of thumb quickly became an established and cherished part of the epidemiological can...
متن کاملDoes Social Judgment Diminish Rule Breaking?
We experimentally investigate the extent to which social observability of one’s actions and the possibility of social non-monetary judgment affect the decision to engage in rule breaking behavior. We consider three rule breaking scenarios — theft, bribery and embezzlement — in the absence of any formal enforcement mechanism. By involving a student sample characterized by cultural heterogeneity ...
