The case-slot identity theory

Many people have noted the similarities between case theories in linguistics and frame representations in artificial intelligence. In particular, the cases of a verb seem to correspond to the slots of a frame. This has led many people, including Fillmore [1977] and Winston [1977] to assert that cases and slots are one and the same. This hypothesis has not attracted much attention, probably because the notion of “slot” in frame representations is so underconstrained that the theory would seem to be content free. In this note, we wish to show that this is not true. For one thing, the case-slot identity theory can explain the difficulty linguists have had in deciding how many cases there are. Furthermore, its adoption will place certain interesting, and plausible constraints on the frame and case theories compatible with it.     

THE SOCIOLOGY AND THEOLOGY OF CREATIONIST OBJECTIONS TO EVOLUTION: HOW BLOOD MARKS THE BOUNDS OF THE CHRISTIAN BODY

The staying power of creationist objections to evolution needs explanation. It depends on the use of “blood” language. Both William Jennings Bryan and, a century later, Ken Ham connect evolution with the blood of predation and the blood of apes, and both also connect evolution with the blood of atonement. Drawing on Mary Douglas and Bettina Bildhauer, I suggest that blood becomes important to societies that image the social body on the human body. Blood reveals the body as porous and vulnerable and therefore needing social work to be constructed as whole and bounded. Blood is the place where society conducts this work. I conclude that blood language is ineliminable from Christian discourse and indeed from discourses that model the social on the individual body. The solution, I suggest, is not to avoid the language of blood, but to continue to use it in ways that broaden its focus from human sin to human and animal suffering.     

Effects of sleep deprivation on executive functioning,cognitive abilities,metacognitive confidence,and decision making

Performance on many decision‐making tasks is underpinned by metacognitive monitoring, cognitive abilities, and executive functioning. Fatigue‐inducing conditions, such as sleep loss, compromise these factors, leading to decline in decision performance. Using a 40‐hr sleep deprivation protocol, we examined these factors and the resulting decision performance. Thirteen Australian Army male volunteers (aged 20–30 years) were tested at multiple time points on psychomotor vigilance, inhibitory control, task switching, working memory, short‐term memory, fluid intelligence, and decision accuracy and confidence in a medical diagnosis‐making test. Assessment took place in the morning and night over two consecutive days, during which participants were kept awake. Consistent with previous work, cognitive performance declined after a night without sleep. Extending previous findings, self‐regulation and self‐monitoring suffered significantly greater declines immediately after the sleepless night. These results indicate that the known decline in complex decision‐making performance under fatigue‐inducing conditions might be facilitated by metacognitive rather than cognitive mechanisms.     

The Poor Lady Immured

This essay offers cautionary considerations on what has come to be called “public philosophy.” A conception of philosophy is set forth using Socrates as the paradigm of relentless philosophical questioning. The essay then outlines three types of public philosophy: a philosophy situated in a public setting, a philosophy whose content is modified for a varied public, and a philosophy that functions as normative consensus. The most important of these three is the philosophy modified for the public. The discussion notes examples of public philosophy from the history of philosophy, and examines the contribution of eighteenth‐century philosophers (such as David Hume) to a version of public philosophy. The risks of public philosophy are noted—in particular, that a modified philosophy may substitute the inculcation of belief over the modeling of philosophy. The essay concludes by noting that the university classroom remains an important but forgotten venue of public philosophy.     

Uncovering the trail of positive affect in the job attitudes literature: A systematic review

A review of the organisational psychology literature suggests that researchers have examined at least four job attitude constructs: job satisfaction, work/task satisfaction, job involvement, and organisational commitment. Less, however, is known about why the four different job attitudes vary in magnitude as predictors of vital organisational outcomes. In this systematic review, I propose that positive affect is central in explaining the differential effects of these job attitudes on organisational outcomes. The review then explicates patterns of results underlying prior studies on these job attitudes and presents an overarching proposition: Accurate conceptualisation and measurement of the affective component underlying each job attitude will help illustrate how, and to what extent, each job attitude leads to desirable organisational outcomes. Finally, four key suggestions for further job attitudes research are presented: (a) enhancing conceptualisation and measurement of positive affect in job attitudes, (b) developing an overarching theory of positive affect, (c) focusing on discrete positive emotions, and (d) looking beyond existing current job attitude constructs. This work complements the current affective epoch of job attitudes research, uncovering the trail of positive affect as it has informed the job attitudes literature historically and suggesting its theoretical and practical developments for the future.
