Estimating the Organizational Costs of Sexual Harassment: The Case of the U.S. Army

A general model for estimating the organizational costs of sexual harassment in the workplace is proposed along with model-specific costing formulas. A partial implementation of the model is applied to sexual harassment incidence data for the Army gathered as part of a large-scale survey of the U.S. military services. Results indicate that the total annual cost of sexual harassment in the U.S. Army in 1988 was over $250,000,000. Organizational implications are discussed.     

Impaired modulation of corticospinal excitability following subthreshold rTMS in focal hand dystonia

Previous studies have demonstrated that subthreshold 1 Hz repetitive transcranial magnetic stimulation (rTMS) causes a decrease in corticospinal excitability in neurologically normal subjects. The effects of subthreshold 1 Hz rTMS upon corticospinal excitability and intracortical inhibition in subjects with focal hand dystonia (FHD) is not yet clear. The purpose of this study was to examine the effects of low intensity 1 Hz rTMS upon these variables in control and FHD subjects. We recorded electromyographic (EMG) from the first dorsal interosseous (FDI) muscle of the dominant hands of seven control subjects, and seven affected hands of five FHD subjects. We used single and paired pulse TMS to examine motor evoked potential (MEP) amplitude, short interval intracortical inhibition (ICI) and silent period duration before, during and after 20 min of low intensity 1 Hz rTMS. MEP amplitude decreased significantly over the course of the rTMS in control subjects, but did not change in FHD subjects. Silent period duration was significantly longer in control subjects after rTMS, but there was no change in FHD subjects. There was no significant change in ICI after rTMS in either subject group, despite the rTMS intensity being set to preferentially activate intracortical inhibitory networks. This suggests that low intensity 1 Hz rTMS may have limited application in the normalisation of inhibitory function in FHD.     

Gender-typical responses to sexual and emotional infidelity as a function of mortality salience induced self-esteem striving

The authors propose that gender-differentiated patterns of jealousy in response to sexual and emotional infidelity are engendered by the differential impact of each event on self-esteem for men and women. Study 1 demonstrated that men derive relatively more self-esteem from their sex lives, whereas women's self-esteem is more contingent on romantic commitment. Based on terror management theory, it is predicted that if gender-differentiated responses to infidelity are motivated by gender-specific contingencies for self-esteem, they should be intensified following reminders of mortality. In Study 2, mortality salience (MS) increased distress in response to sexual infidelity for men and emotional infidelity for women. Study 3 demonstrated that following MS, men who place high value on sex in romantic relationships exhibited greater distress in response to sexual infidelity, but low-ex-value men's distress was attenuated. The authors discuss the implications for evolutionary and self-esteem-based accounts of jealousy as well as possible integration of these perspectives.     

Spreading activation or spooky action at a distance?

How do preexisting connections among a word's associates facilitate its cued recall and recognition? A spreading-activation model assumes activation spreads to, among, and from a studied word's associates, and that its return is what strengthens its representation. An activation-at-a-distance model assumes strengthening is produced by the synchronous activation of the word's associates. The spread model predicts that connections among the studied word's associates will have a greater effect on memory when more of its associates return activation. The distance model predicts that total connections are important, not their direction. The results of cued recall experiments supported the distance model in showing that that connections among the associates facilitated recall regardless of the number of returning connections.     

Are implicitly activated associates selectively activated?

What constitutes a word’s associative past? Words differ in how many associates they activate in memory and, following a brief encounter, those with fewer associates are more likely to be recalled in the presence of related cues. The issue addressed in the present article is whether associative set size effects are produced through the selective activation of strong associates or through the activation of both strong and weak associates. The set size of the strongest associates was varied factorially with the set size of the associates of these associates. We assume that associate set size indexes a word’s weaker associates. Experiments 1 and 2 showed that recall varied inversely with both target and associate set sizes. Such results held over variations in study time and participant age. Experiment 3 showed that weak associates of the target had a greater effect on recall when there were more connections among the strongest associates in the set. The findings suggest that activation is not strength selective but includes both weak and strong associates.
