The Heart Wants What It Wants: Effects of Desirability and Body Part Salience on Distance Perceptions (Heath)
Previous research has shown that the desirability of an object influences perceived distance from the object, such that desirable objects are perceived as closer than objects that are not desirable (Balcetis & Dunning, 2010). It has also been suggested that metaphors reflect how our knowledge is represented; so, for example, making the head or heart more salient produces characteristics commonly associated with those body parts (i.e., emotionality for the heart, rationality for the head) (Fetterman & Robinson, 2013). The current study examined the effects of head or heart salience and object desirability on distance perception. We hypothesized that, since common idioms relate the heart to desirability, salience of the heart would cause desirable objects to be perceived as closer than would salience of the head, but there would be no difference between the head and heart conditions when the object was neutral. To test this hypothesis, we conducted two experiments in which participants had their attention drawn to their head or their heart by placing their hand there while making an action-based (haptic) measure of distance to an object. After finding no significant results in Experiment 1, in Experiment 2 a verbal measure of distance perception was added and participants completed a two-minute filler task while touching the assigned body part to strengthen the body part salience effect before estimating distance. Besides replicating Proffittâs 2006 finding that haptic estimates of environmental features are more accurate than verbal estimates, we found no significant results in Experiment 2
Physicists Thriving with Paperless Publishing
The Stanford Linear Accelerator Center (SLAC) and Deutsches Elektronen
Synchrotron (DESY) libraries have been comprehensively cataloguing the High
Energy Particle Physics (HEP) literature online since 1974. The core database,
SPIRES-HEP, now indexes over 400,000 research articles, with almost 50% linked
to fulltext electronic versions (this site now has over 15 000 hits per day).
This database motivated the creation of the first site in the United States for
the World Wide Web at SLAC. With this database and the invention of the Los
Alamos E-print archives in 1991, the HEP community pioneered the trend to
"paperless publishing" and the trend to paperless access; in other words, the
"virtual library." We examine the impact this has had both on the way
scientists research and on paper-based publishing. The standard of work
archived at Los Alamos is very high. 70% of papers are eventually published in
journals and another 20% are in conference proceedings. As a service to
authors, the SPIRES-HEP collaboration has been ensuring that as much
information as possible is included with each bibliographic entry for a paper.
Such meta-data can include tables of the experimental data that researchers can
easily use to perform their own analyses as well as detailed descriptions of
the experiment, citation tracking, and links to full-text documents.Comment: 17 pages, Invited talk at the AAAS Meeting, February 2000 in

Averages and moments associated to class numbers of imaginary quadratic fields
For any odd prime , let denote the -part of the
class number of the imaginary quadratic field .
Nontrivial pointwise upper bounds are known only for ; nontrivial
upper bounds for averages of have previously been known only for
. In this paper we prove nontrivial upper bounds for the average of
for all primes , as well as nontrivial upper bounds
for certain higher moments for all primes .Comment: 26 pages; minor edits to exposition and notation, to agree with

Simultaneous Integer Values of Pairs of Quadratic Forms
We prove that a pair of integral quadratic forms in 5 or more variables will
simultaneously represent "almost all" pairs of integers that satisfy the
necessary local conditions, provided that the forms satisfy a suitable
nonsingularity condition. In particular such forms simultaneously attain prime
values if the obvious local conditions hold. The proof uses the circle method,
and in particular pioneers a two-dimensional version of a Kloosterman
refinement.Comment: 63 page

Increasing food familiarity without the tears. A role for visual exposure?
Research has established the success of taste exposure paradigms as a means of increasing childrenâs
acceptance, and liking, of previously unfamiliar or disliked foods. Yet, parents report that they tend to
avoid the stress associated with repeatedly offering their children foods that are likely to be rejected.
Given that successful taste exposure programmes often enhance childrenâs familiarity with a foodâs
appearance, as well as its taste, this article reviews the potential for exposure interventions that do not
require repeated tastings to bring about positive attitude changes towards healthy foods. Recent
evidence from studies that expose toddlers to picture books about fruit and vegetables suggest that
familiarity with the origins and appearance of unfamiliar foods might increase childrenâs willingness to
accept these into their diets
