Outing and Virtue Ethics

The paper argues that the two dominant approaches towards the moral issues surrounding outing are too weak to handle the latter's complexity and would benefit from being made part of a broader and richer framework, namely, that of virtue ethics. One dominant approach begins by arguing that people do not have the right to privacy in matters of sexual orientation (not behaviour), and so outing gay people does not violate such a right. It continues by arguing that living a dignified life requires the agent to refuse to keep secret the gay sexual orientation of others. The second dominant approach, opposed to the first, argues that gay people have a right to the privacy of sexual orientation, and so outing them is prima facie wrong. Both approaches, the paper argues, are too weak to handle the complexity of outing: the first suffers from emphasizing only one subset of the virtues (dignity, pride, and so on), while the second is too weak to explain fully why in some cases outing is permissible. Virtue ethics is a much richer framework from which to address the complexity of outing.     

Ipsilateral Loudness Adaptation Over Multiple Intensity Levels

Three mirror tracing experiments were conducted to investigate the connection between perception and motor behavior. In the first experiment, some subjects traced a hex-maze, other subjects traced a hex-maze after observing a model trace, others traced a hex-maze after reading instructions on mirror images, and others traced a hex-maze after having observed a model and heard the instructions. There were no significant differences between the groups' error scores, but their time scores differed significantly, although not always in the predicted direction. In Experiment 2, the subjects were to trace selected letters of the alphabet. Error scores for the second experiment did not differ much from those for the first experiment. In Experiment 3, the experimenter gave each subject commands for the correct directions of movement, using the subject's body as a frame of reference. There was little improvement in motor performance. These results suggest that the visual information presented in the mirror captured the subjects' attention and blocked their motor tracing program.     

Individual Differences in Monitoring Failures of Automation

Subjects included 24 non-pilots who performed simulated flight-related tasks of tracking, fuel-management, and system monitoring. Tracking and fuel management were performed manually, whereas system monitoring was automated. Subjects were required to detect system malfunctions not detected by the automation (automation failures). The reliability of the automation remained constant or varied over time. Subjects detected significantly fewer automation failures in the constant-reliability automation condition than in the variable-reliability condition. Inefficiency in monitoring for automation failure was examined in relation to three individual-difference measures: the Complacency Potential Rating Scale, the Eysenck Personality Inventory (introversion-extraversion), and a modified version of Thayer's Activation-Deactivation Adjective Check List (energetic arousal). These measures were not significantly intercorrelated, suggesting their relative independence. For subjects with high-complacency-potential scores, there was a correlation of - .42 between complacency potential and detection rate of automation failures. Introversion-extraversion was unrelated to monitoring performance. Finally, high energetic-arousal subjects had initially higher detection rates in the constant-reliability condition than did low-arousal subjects. The results suggest a modest relationship between individual differences in complacency potential and energetic-arousal and automation-related monitoring inefficiency.     

Adaptive Automation for Human Supervision of Multiple Uninhabited Vehicles: Effects on Change Detection,Situation Awareness,and Mental Workload

Human operators supervising multiple uninhabited air and ground vehicles (UAVs and UGVs) under high task load must be supported appropriately in context by automation. Two experiments examined the efficacy of such adaptive automation in a simulated high workload reconnaissance mission involving four subtasks: (a) UAV target identification; (b) UGV route planning; (c) communications, with embedded verbal situation awareness probes; and (d) change detection. The results of the first “baseline” experiment established the sensitivity of a change detection procedure to transient and nontransient events in a complex, multi-window, dynamic display. Experiment 1 also set appropriate levels of low and high task load for use in Experiment 2, in which three automation conditions were compared: manual; static automation, in which an automated target recognition (ATR) system was provided for the UAV task; and adaptive automation, in which individual operator change detection performance was assessed in real time and used to invoke the ATR if and only if change detection accuracy was below a threshold. Change detection accuracy and situation awareness were higher and workload was lower for both automation conditions compared to manual performance. In addition, these beneficial effects on change detection and workload were significantly greater for adaptive compared to static automation. The results point to the efficacy of adaptive automation for supporting the human operator tasked with supervision of multiple uninhabited vehicles under high workload conditions.     

Effect of Mg content on Portevin–Le Chatelier band strain in Al–Mg sheet alloys

Experimental measurements of stress drops and band strains in type-B Portevin–Le Chatelier (PLC) bands were carried out for 5xxx series Al–Mg sheets with Mg content between 1.8 and 4.5?wt%. While the stress drops increase with global strain, the band strain values in all the samples follow a common linear relationship with global strain. The results indicate that the type-B PLC band strain is independent of solute content at given strain rate.     

Selected Ethical Issues in the Analysis and Reporting of Research: Survey of Business School Faculty in Malaysia

This study reports the perceptions of business school faculty on ethical behaviors related to data analysis and research reporting as well as the prevalence of such behaviors in their academic environment. Survey data for the study were obtained from a sample of 102 business school faculty from five government-funded universities in Malaysia. Study results showed that a majority of the respondents considered practices such as fabrication, manipulation, and distortion of data to be ethically unacceptable, and these behaviors were reported to be least prevalent. In contrast, the practice of misapplying statistical techniques was considered ethically acceptable and reported to be quite prevalent. On research reporting, although a majority of the respondents agreed that plagiarism and taking undeserved authorship credit were ethically unacceptable, they also reported having observed the frequent occurrence of such behaviors. Finally, practices such as cutting up research data and simultaneous submissions to more than one publication outlet at the same time were less likely to be viewed as unethical and seen to be quite a common practice. In general, the findings of this study indicate that the perceptions of the ethicality and frequency of occurrence of behaviors related to data analysis and research reporting vary among business school faculty.     

Analysis of the role of associative inhibition in perceptual learning by means of the same-different task

In Experiment 1a, participants were exposed, over a series of trials, to separate presentations of 2 similar checkerboard stimuli, AX and BX (where X represents a common background). In one group, AX and BX were presented on alternating trials (intermixed), in another, they were presented in separate blocks of trials (blocked). The intermixed group performed to a higher standard than the blocked group on a same-different test. A superiority of intermixed over blocked exposure was also evident in a within-subject design (Experiment 1b) and when the test required discrimination between a preexposed stimulus and the background (e.g., AX vs. X), even if the background changed between preexposure and test (AY vs. Y) (Experiment 2). In Experiment 3, the intermixed/blocked effect was observed when, in preexposure, stimulus presentations were alternated with the background alone (e.g., AX/X). This suggests that the perceptual learning effect is not the consequence of inhibitory associations between unique features but to increased salience of those features. Experiment 4 confirmed this finding and also ruled out an account of the effect in terms of trial spacing.     

A diffusion model analysis of the effects of aging on brightness discrimination

The effects of aging on decision time were examined in a brightness discrimination experiment with young and older subjects (ages, 60-75 years). Results showed that older subjects were slightly slower than young subjects but just as accurate. Ratcliff's (1978) diffusion model was fit to the data, and it provided a good account of response times, their distributions, and response accuracy. There was a 50-msec slowing of the nondecision components of response time for older subjects relative to young subjects, but response criteria settings and rates of accumulation of evidence from stimuli were roughly equal for the two groups. These results are contrasted with those obtained from letter discrimination and signal-detection-like tasks.
