Tedium in the life and work of professional women as compared with men

The experience of tedium, its antecedents, and its chronic life and work correlates in professional women as compared to men, were the foci of the present study. Tedium was defined as a general experience of physical, emotional, and mental exhaustion characterized by depression; emotional and physical depletion; burnout; and negative attitudes toward one's life, one's environment, and oneself. Women did not differ significantly from men in the experience of tedium. This is particularly noteworthy, since women reported less positive features and rewards and more negative features, pressures, and stresses in their work environments than men. There were far more significant sex differences in work features than in life-outside-of-work features, and many variables emerged as equally important tedium correlates for both sexes. For both sexes, life outside of the work sphere provided more positive aspects, while work presented more negative ones.     

Generating interior search directions for multiobjective linear programming

A new multiobjective linear programming (MOLP) algorithm is presented. The algorithm uses a variant of Karmarkar's interior-point algorithm known as the affine-scaling primal algorithm. Using this single-objective algorithm, interior search directions are generated and used to provide an approximation to the gradient of the (implicitly known) utility function. The approximation is guided by assessing locally relevant preference information for the various interior directions through interaction with a decision maker (DM). The resulting algorithm is an interactive approach that makes its progress towards the solution through the interior of the constraints polytope.     

The visual search analogue of latent inhibition: Implications for theories of irrelevant stimulus processing in normal and schizophrenic groups

Latent inhibition (LI) is a robust phenomenon that is demonstrated when a previously inconsequential stimulus is less effective in a new learning situation than a novel stimulus. Despite LI’s simplicity, there is considerable disagreement as to its theoretical basis. Attentional theories claim that unattended stimulus preexposures reduce stimulus associability. Alternatively, it has been asserted that associability is unaffected and that LI is a result of competition/retrieval processes. The present article reviews a series of visual search studies, some with normal subjects, both undifferentiated and divided into low and high schizotypals, and others with pathologies that entail dysfunctional attention, such as schizophrenia, Parkinson’s disease, and anxiety. The visual search conditions were designed to model those of traditional LI experiments, while tapping attentional processes independently of the learning scores that index LI. A variety of evidence from these and other studies is used to support the involvement of attentionaland retrieval processes in LI. A model of the mechanism of action of these processes in LI is presented, together with its application to schizophrenia.
