Velocity Gauge

<div> <div> <p> </p><div> <div> <div> <p>This work presents the first simulations of the full optical rotation (OR) tensor at coupled cluster with single and double excitations (CCSD) level in the modified velocity gauge (MVG) formalism. The CCSD-MVG OR tensor is origin independent, and each tensor element can in principle be related directly to experimental measurements on oriented systems. We compare the CCSD results with those from two density functionals, B3LYP and CAM-B3LYP, on a test set of 22 chiral molecules. The results show that the functionals consistently overestimate the CCSD results for the individual tensor components and for the trace (which is related to the isotropic OR), by 10-20% with CAM-B3LYP and 20-30% with B3LYP. The data show that the contribution of the electric dipole-magnetic dipole polarizability tensor to the OR tensor is on average twice as large as that of the electric dipole-electric quadrupole polarizability tensor. The difficult case of (1S,4S)-(–)-norbornenone also reveals that the evaluation of the former polarizability tensor is more sensitive than the latter. We attribute the better agreement of CAM-B3LYP with CCSD to the ability of this functional to better reproduce electron delocalization compared with B3LYP, consistently with previous reports on isotropic OR. The CCSD-MVG approach allows the computation of reference data of the full OR tensor, which may be used to test more computationally efficient approximate methods that can be employed to study realistic models of optically active materials. </p> </div> </div> </div> </div> </div>

Self Interest

Even if we can rise above self-interest, we may just be slaves of our passions. But the motivational power of reason, via moral beliefs, has been understated, even in the difficult case of temptation. Experiments show that often when we succumb, it is due in part to a change in moral (or normative) judgment. We can see this by carefully examining a range of experiments on motivated reasoning, moral licensing, moral hypocrisy, and moral identity. Rationalization, perhaps paradoxically, reveals a deep regard for reason, to act in ways we can justify to ourselves and to others. The result is that we are very often morally motivated or exhibit moral integrity. Even when behaving badly, actions that often seem motivated by self-interest are actually ultimately driven by a concern to do what’s right.

Definition Of

Paniagua, et al. suggested that the definition of a “difficult” case in psychotherapy implies a relational definition involving the characteristics of the patient, the case, and the therapist. This study concerned this hypothesis with 44 graduate students in social work who received the Difficult Case Questionnaire representing examples of variables across each domain, e.g., motivation of the client, nature of the disorder, generic factors, and orientation of the therapist. The results were compared with the 1993 findings reported by Paniagua, et al., for a group of professionals in mental health practice. As in the earlier study, the present sample also agreed that, although all such domains are important in the formulation of that definition, their importance is not equal. Whereas professionals rated patient's, case's, and therapist's characteristics as the most important order of domains in that definition, students in this study agreed on the order of therapist's, patient's, and case's characteristics.
