Title: On effects that do occur versus effects that can be made to occur
Following Douglas Mook's lead we distinguish between research on “effects that can be made to occur” and research on “effects that do occur” and argue that both can contribute to the advancement of knowledge. We further suggest that current social psychological research focuses too much on the former type of effects. Given the discipline's emphasis on innovation, many published effects are shown to exist under very specific circumstances, i.e., when numerous moderator variables are set at a particular level. One often does not know, however, how frequently these circumstances exist for people in the real world. Studies on effects that can be made to occur are thus an incomplete test of most theories about human cognition and behavior. Using concrete examples, this article discusses the shortcomings of a field that limits itself to identifying effects that might—or might not—be relevant. We argue that it is just as much a scientific contribution to show that a given effect actually does occur as it is to provide initial evidence for a new effect that could turn out to be important. The article ends with a series of suggestions for researchers who want to increase the theoretical and practical relevance of their research.  more » « less

  1. Abstract Recent studies have shown that recidivism scoring algorithms like COMPAS have significant racial bias: Black defendants are roughly twice as likely as white defendants to be mistakenly classified as medium- or high-risk. This has led some to call for abolishing COMPAS. But many others have argued that algorithms should instead be given access to a defendant's race, which, perhaps counterintuitively, is likely to improve outcomes. This approach can involve either establishing race-sensitive risk thresholds, or distinct racial ‘tracks’. Is there a moral difference between these two approaches? We first consider Deborah Hellman's view that the use of distinct racial tracks (but not distinct thresholds) does not constitute disparate treatment since the effects on individuals are indirect and does not rely on a racial generalization. We argue that this is mistaken: the use of different racial tracks seems both to have direct effects on and to rely on a racial generalization. We then offer an alternative understanding of the distinction between these two approaches—namely, that the use of different cut points is to the counterfactual comparative disadvantage, ex ante, of all white defendants, while the use of different racial tracks can in principle be to the advantage of all groups, though some defendants in both groups will fare worse. Does this mean that the use of cut points is impermissible? Ultimately, we argue, while there are reasons to be skeptical of the use of distinct cut points, it is an open question whether these reasons suffice to make a difference to their moral permissibility.

  2. Multiple line outages that occur together show a variety of spatial patterns in the power transmission network. Some of these spatial patterns form network contingency motifs, which we define as the patterns of multiple outages that occur much more frequently than multiple outages chosen randomly from the network. We show that choosing N-k contingencies from these commonly occurring contingency motifs accounts for most of the probability of multiple initiating line outages. This result is demonstrated using historical outage data for two transmission systems. It enables N-k contingency lists that are much more efficient in accounting for the likely multiple initiating outages than exhaustive listing or random selection. The N-k contingency lists constructed from motifs can improve risk estimation in cascading outage simulations and help to confirm utility contingency selection.

  3. Bradley, R D (Ed.)
    Identification of cryptic species often relies on invasive techniques such as comparison of cranial morphology or generation of DNA sequences. Myotis lucifugus and M. septentrionalis recently have been reported to occur near the Texas border in Oklahoma and Louisiana, respectively, and due to similarity of appearance, both species easily could be mistaken for M. austroriparius, a common inhabitant of East Texas. All three species co-occur across much of the southeastern United States. Myotis septentrionalis recently was listed under the Endangered Species Act as Endangered, and M. lucifugus has seen drastic reductions in abundance due to white-nose syndrome. Therefore, special care is needed when capturing any of these species due to the cryptic nature of their external morphology and the potential for misidentification in the field. The objective of this study was to determine if wing measurements obtained in the field could be used to differentiate among these three species. Measurements of 13 wing elements from 45 museum specimens were compared using univariate and multivariate statistics. Significant multivariate differences among species were detected, indicating that some wing characteristics may be effective for differentiation. These wing characteristics were compiled into a dichotomous key that researchers can use to easily identify species in the field. Using this technique, non-target species can be released quickly without harm, whereas individuals of species of interest can be confidently collected for scientific research.

  4. Effect systems have been a subject of active research for nearly four decades, with the most notable practical example being checked exceptions in programming languages such as Java. While many exception systems support abstraction, aggregation, and hierarchy (e.g., via class declaration and subclassing mechanisms), it is rare to see such expressive power in more generic effect systems. We designed an effect system around the idea of protecting system resources and incorporated our effect system into the Wyvern programming language. Similar to type members, a Wyvern object can have effect members that can abstract lower-level effects, allow for aggregation, and have both lower and upper bounds, providing for a granular effect hierarchy. We argue that Wyvern’s effects capture the right balance of expressiveness and power from the programming language design perspective. We present a full formalization of our effect-system design, showing that it allows reasoning about authority and attenuation. Our approach is evaluated through a security-related case study.

  5. Many augmented reality (AR) applications require observers to shift their gaze between AR and real-world content. To date, commercial optical see-through (OST) AR displays have presented content at either a single focal distance, or at a small number of fixed focal distances. Meanwhile, real-world stimuli can occur at a variety of focal distances. Therefore, when shifting gaze between AR and real-world content, in order to view new content in sharp focus, observers must often change their eye’s accommodative state. When performed repetitively, this can negatively affect task performance and eye fatigue. However, these effects may be under reported, because past research has not yet considered the potential additional effect of distracting real world backgrounds.An experimental method that analyzes background effects is presented, using a text-based visual search task that requires integrating information presented in both AR and the real world. An experiment is reported, which examined the effect of a distracting background versus a blank background, at focal switching distances of 0, 1.33, 2.0, and 3.33 meters. Qualitatively, a majority of the participants reported that the distracting background made the task more difficult and fatiguing. Quantitatively, increasing the focal switching distance resulted in reduced task performance and increased eye fatigue. However, changing the background, between blank and distracting, did not result in significant measured differences. Suggestions are given for further efforts to examine background effects.
