Valuing the future: a MADA example involving nuclear waste storage

Intertemporal decision making involves decisions that have consequences that span several periods of time and often extend far into the future. The purpose of this paper is to discuss and highlight the differences associated with different evaluation methods designed to cope with the long-term impacts of a decision including discounting. The concepts and ideas are illustrated in the context of a decision about a nuclear waste facility. We show how applying different discounting methodologies can greatly affect the decision made, especially over long time periods. © 1998 John Wiley & Sons, Ltd.     

From landsmanshaften to vinkln: Mediating community among Yiddish speakers in America

Vinkln (“corners”) in America have spread since the 1970s as an organizational strategy by Yiddish-speaking, non-pietistic, East European Jewish immigrants, many of whom have a Holocaust experience. The vinkln provide a privatized, immersive experience for Yiddish language and culture as a way to offer community identity to Yiddish speakers within the wider Jewish community. They arose out of landsmanschaften, or “hometown associations,” in the early twentieth century, but the vinkln function to ritually reproduce culture rather than offer mutual aid based on old-country affiliation. Although secularized, the organized social structure and performed communication of the vinkln invoke rituals and roles of Jewish religious services from traditional community experience. They displace old-country affiliations with pronounced loyalties to Israel and America, although the location of Yiddish in performance is often centered in Poland. The vinkln mediate community by suggesting cultural reproduction even as the bonds of language and society among Yiddish speakers are weakening. Its symbols and associations are restricted to an elderly age cohort, and therefore not likely to perpetuate the very culture that its organizers purport to preserve. It is differentiated from other structures of Yiddish conservation and appreciation such as Internet networks and community center conversation groups.

Normativity à la Mode

This paper sets out to raise questions about the metaphor of the spaceof reasons. It argues that a proper appreciation of Wittgensteinundermines the metaphysical or dualistic way of taking the metaphor thatis supposed to prevent the naturalization of reason.     

Collaborative Discovery in a Scientific Domain

This study compares Pairs of subjects with Single subjects in a task of discovering scientific laws with the aid of experiments. Subjects solved a molecular genetics task in a computer micro-world (Dunbar, 1993). Pairs were more successful in discovery than Singles and participated more actively in explanatory activities (i.e., entertaining hypotheses and considering alternative ideas and justifications). Explanatory activities were effective for discovery only when the subjects also conducted crucial experiments. Explanatory activities were facilitated when paired subjects made requests of each other for explanation and focused on them. The study extends from individual to collaborative discovery activities the importance to the discovery process of setting goals to find hypotheses and evidence (Dunbar, 1993) and to construct explanations of phenomena and processes encountered in examples (Chi, Bassok, Lewis, & Glaser, 1989).     

Parent-infant interaction: a growth model approach

The aim of this study is to compare the interaction of fathers and mothers with their 10–12 months old infants (n = 97; parental sensitivity and mood, and infant mood) during five structured contiguous play segments, and to examine the utility of individual growth modeling. Conventional comparison of means across play-segments showed that parents were equally responsive, but mothers were happier than fathers, and infants were equally happy during interaction with both parents. Sensitivity and mood were more strongly related for mothers than for fathers. Uni- and multivariate growth models revealed fine-grained patterns not seen in conventional analysis: (a) parental and infant mood decreased across play more for mothers than for fathers, (b) parental sensitivity in one play-segment predicted parental mood and infant mood in the next segment, (c) change in infants’ mood was related to change in sensitivity in mothers, and to change in mood in fathers, and (d) mothers’ sensitive interaction with the infant was predicted by family socio-demographic background.     

Vision and touch: multiple or multisensory representations of objects?

The relationship between visually and haptically derived representations of objects is an important question in multisensory processing and, increasingly, in mental representation. We review evidence for the format and properties of these representations, and address possible theoretical models. We explore the relevance of visual imagery processes and highlight areas for further research, including the neglected question of asymmetric performance in the visuo-haptic cross-modal memory paradigm. We conclude that the weight of evidence suggests the existence of a multisensory representation, spatial in format, and flexibly accessible by both bottom-up and top-down inputs, although efficient comparison between modality-specific representations cannot entirely be ruled out.     

Gun safety management with patients at risk for suicide

Guns in the home are associated with a five-fold increase in suicide. All patients at risk for suicide must be asked if guns are available at home or easily accessible elsewhere, or if they have intent to buy or purchase a gun. Gun safety management requires a collaborative team approach including the clinician, patient, and designated person responsible for removing guns from the home. A call-back to the clinician from the designated person is required confirming that guns have been removed and secured according to plan. The principle of gun safety management applies to outpatients, inpatients, and emergency patients, although its implementation varies according to the clinical setting.     

Foundations of Representation: Where Might Graphical Symbol Systems Come From?

It has been suggested that iconic graphical signs evolve into symbolic graphical signs through repeated usage. This article reports a series of interactive graphical communication experiments using a 'pictionary' task to establish the conditions under which the evolution might occur. Experiment 1 rules out a simple repetition based account in favor of an account that requires feedback and interaction between communicators. Experiment 2 shows how the degree of interaction affects the evolution of signs according to a process of grounding. Experiment 3 confirms the prediction that those not involved directly in the interaction have trouble interpreting the graphical signs produced in Experiment 1. On the basis of these results, this article argues that icons evolve into symbols as a consequence of the systematic shift in the locus of information from the sign to the users' memory of the sign's usage supported by an interactive grounding process.     

The Impact of Personality and Team Context on the Relationship Between Workplace Injustice and Counterproductive Work Behavior

This study ascertains whether the impact of workplace injustice on counterproductive work behavior is moderated by personality and team context. A sample of 131 public-service employees completed a questionnaire that assessed the extent to which they receive distributive, procedural, and interactional justice. Furthermore, team commitment, coworker satisfaction, and Big Five personality traits were assessed. Finally, respondents estimated the frequency with which they and their colleagues engage in counterproductive behaviors. Procedural, distributive, and interactional injustice all provoked counterproductive behaviors. The effect of justice on these destructive acts diminished when team commitment was elevated, coworker satisfaction was limited, agreeableness was pronounced, and neuroticism was reduced. The findings confirm that vulnerability amplifies the impact of injustice, but interdependence can diminish this effect.
