This collection of essays focuses on the concepts of tolerance and intolerance as it commemorates the life of James Parkes - the man who pioneered the study of antisemitism and Jewish-non-Jewish relations. The essays analyse many different examples of antisemitism, ambivalence and philosemitism.

We examine two different descriptions of the behavioral functions of the hippocampal system. One emphasizes spatially organized behaviors, especially those using cognitive maps. The other emphasizes memory, particularly working memory, a short-term memory that requires iexible stimulus-response associations and is highly susceptible to interference. The predictive value of the spatial and memory descriptions were evaluated by testing rats with damage to the hippocampal system in a series of experiments, independently manipulating the spatial and memory characteristics of a behavioral task. No (...) dissociations were found when the spatial characteristics of the stimuli to be remembered were changed; lesions produced a similar deficit in both spatial and nonspatial test procedures, indicating that the hippocampus was similarly involved regardless of the spatial nature of the task. In contrast, a marked dissociation was found when the memory requirements were altered. Rats with lesions were able to perform accurately in tasks that could be solved exclusively on the basis of reference memory. They performed at chance levels and showed no signs of recovery even with extensive postoperative training in tasks that required working memory. In one experiment all the characteristics of the reference memory and working memory procedures were identical except the type of memory required. Consequently, the behavioral dissociation cannot be explained by differences in attention, motivation, response inhibition, or the type of stimuli to be remembered. As a result of these experiments we propose that the hippocampus is selectively involved in behaviors that require working memory, irrespective of the type of material that is to be processed by that memory.

A common occurrence in television news is the showing of graphic scenes of human suffering. It was hypothesized that viewing such scenes could be harmful to a segment of the population. A controlled experiment examined the impact of images showing victim blood inserted into into television news stories about auto accidents. The amount of blood shown was manipulated, resulting in three video versions, roughly in terms of low, medium, and high. Participants were measured beforehand on the variable of "locus of (...) control" and randomly assigned to one of the three treatment groups. Dependent variables included emotional impact and mean world syndrome. The results suggested blood shown on screen makes a difference in the perceived emotional impact of the story. Locus of control was found to be linked to mean world syndrome. The findings suggest that the quest for hardhitting news and high ratings must be tempered with the knowledge that some viewers are adversely affected by these graphic scenes of human suffering.

An empirical law or evidence which supports a theory tends to have the greatest scientific value when it seemed improbable before it was investigated. Evidence which falsifies a theory tends to have the greatest value when it seemed probable that the investigation would confirm the theory. A scientist who wishes to optimize his contribution to knowledge probably will investigate most frequently hypotheses which seem neither very probable nor very improbable of being confirmed. This strategy leads neither to a maximum number (...) of confirmations of a theory, nor to a set of tests which are maximally severe. (shrink)

Most of the world's population and the vast majority of the world's poor live and work in villages. Their activities are usually centred in households, but interactions among households shape the impacts of policy, market and environmental changes on rural production, incomes, employment and migration. This book presents a generation of villagewide economic modelling designed to capture these interactions when assessing the impacts of policy, market and environmental changes on rural economies in less developed countries. The authors present a general (...) framework for modelling village economies based on computable general-equilibrium techniques, estimate models for villages and a village-town in five different countries, and use these models to conduct a series of comparative experiments. The findings offer explanations for some paradoxical outcomes of exogenous shocks as their influence winds its way through rural economies, and they underline the importance of adopting a local economy-wide perspective when designing development policies.

An uncertainty report describes the extent of an agent’s uncertainty about some matter. We identify two basic requirements for uncertainty reports, which we call faithfulness and completeness. We then discuss two pitfalls of uncertainty assessment that often result in reports that fail to meet these requirements. The first involves adopting a one-size-fits-all approach to the representation of uncertainty, while the second involves failing to take account of the risk of surprises. In connection with the latter, we respond to the objection (...) that it is impossible to account for the risk of genuine surprises. After outlining some steps that both scientists and the bodies who commission uncertainty assessments can take to help avoid these pitfalls, we explain why striving for faithfulness and completeness is important.

On April 16, 2007, Cho Seung-Hui used two semiautomatic handguns to kill 32 persons and then himself at Virginia Tech University in the largest campus shooting in U.S. history. Mr. Cho purchased his handguns from a pawnshop and a gun store in Virginia, where under state law a background check was conducted to determine whether he had any disqualifying criminal or mental health history. The paperwork for the background check was completed at the gun store, and the check itself was (...) conducted through an “instant” system facilitated by a toll-free telephone number. The entire transaction took approximately 20 minutes. At no point was Mr. Cho asked why he wished to purchase the guns. And although he had been deemed a potential danger to himself by a state magistrate in 2005 – which should have disqualified his purchase of a gun under federal law – this information never reached those conducting the background check.

Recently, American Psychologist published a review of the evidence for parapsychology that supported the general claims of psi (the umbrella term often used for anomalous or paranormal phenomena). We present an opposing perspective and a broad-based critique of the entire parapsychology enterprise. Our position is straightforward. Claims made by parapsychologists cannot be true. The effects reported can have no ontological status; the data have no existential value. We examine a variety of reasons for this conclusion based on well-understood scientific principles. (...) In the classic English adynaton, “pigs cannot fly.” Hence, data that suggest that they can are necessarily flawed and result from weak methodology or improper data analyses or are Type I errors. So it must be with psi effects. What we find particularly intriguing is that, despite the existential impossibility of psi phenomena and the nearly 150 years of efforts during which there has been, literally, no progress, there are still scientists who continue to embrace the pursuit.

The sounds that make up spoken words are heard in a series and must be mapped rapidly onto words in memory because their elements, unlike those of visual words, cannot simultaneously exist or persist in time. Although theories agree that the dynamics of spoken word recognition are important, they differ in how they treat the nature of the competitor set—precisely which words are activated as an auditory word form unfolds in real time. This study used eye tracking to measure the (...) impact over time of word frequency and 2 partially overlapping competitor set definitions: onset density and neighborhood density. Time course measures revealed early and continuous effects of frequency (facilitatory) and on set based similarity (inhibitory). Neighborhood density appears to have early facilitatory effects and late inhibitory effects. The late inhibitory effects are due to differences in the temporal distribution of similarity within neighborhoods. The early facilitatory effects are due to subphonemic cues that inform the listener about word length before the entire word is heard. The results support a new conception of lexical competition neighborhoods in which recognition occurs against a background of activated competitors that changes over time based on fine-grained goodness-of-fit and competition dynamics.

A research instrument is developed and preliminarily validated to formally measure the level of national business ethics activity for any country in the world. The seven dimensions measured include (a) academia, (b) business, (c) social or ethical investment, (d) business ethics organizations, (e) government activity, (f) social activist groups, and (g) media coverage. Results from the validation survey and examples are provided for each of the dimensions. The article concludes with future research directions for the instrument.

Previous research has indicated an increase in stress levels and cognitive intrusions after natural disasters. These previous studies have not, however, assessed the impact disaster induced cognitive disruption has on human performance. In the present report, we investigated the impact of the 7.1 magnitude 2010 Christchurch, New Zealand earthquake on self-reported earthquake-induced cognitive disruption and its relationship to performance on the Sustained Attention to Response Task . Participants who self-reported greater cognitive disruption induced by the earthquake also had higher levels (...) of errors of commission during SART . This was even the case when controlling for earthquake-induced anxiety, depression, participant sex, and self-reported sleep amount. Post-disaster assessments need to include the impact of the events directly on cognitive self-regulation and conscious thoughts, in addition to more clinical constructs, such as anxiety and depression.

This article examines the use of images of “light” and “enlightenment” in Edmund Burke’s Reflections on the Revolution in France and in the controversy that greeted the book, with an emphasis on caricatures of Burke and his book by James Gillray and others. Drawing on Hans Blumenberg’s discussion of the metaphor of “light as truth,” it situates this controversy within the broader usage of images of light and reason in eighteenth-century frontispieces and (drawing on the work of J. G. (...) A. Pocock and Albert O. Hirschman) explores the ways in which Burke’s critique of Richard Price operates with a rhetoric that views Price as part of an enlightenment that was inherently “radical” and, hence, a threat to the “enlightenment” that, in Burke’s view, had already been achieved.

MicroRNAs are non‐coding regulators of gene expression and key factors in development, disease, and targets for bioengineering. Consequently, microRNAs have become essential elements of already burgeoning draft plant genome descriptions where their annotation is often particularly poor, contributing unduly to the corruption of public databases. Using the Citrus sinensis as an example, we highlight and review common failings of miRNAome annotations. Understanding and exploiting the role of miRNAs in plant biology will be stymied unless the research community acts decisively to (...) improve the accuracy of miRNAome annotations. We encourage genome annotation teams to do it right or not at all. (shrink)
