A Pilot Study to Determine Gender Differences in the Detection of Deception: Accuracy, Cues, and Skepticism

How accurately people use verbal and nonverbal cues to detect deception appears to be a function of a skeptical orientation toward the truthfulness of the subject. In previous studies, some differences in gender and the detection of deception are cited, but most studies are inconclusive about whether such differences exist. In the present study, university students are asked to judge brief interviews of suspects in a mock crime criminal investigation. Suspects are either guilty or not guilty in the mock crime scenario. Guilty suspects include two persons who are present at the time of the mock crime. A third person, the not guilty suspect, is not present during the mock crime. The subjects are asked to indicate whether they felt each suspect is truthful or deceptive in the suspect\u27s responses to five questions. Subjects are asked to also indicate which, if any, of six nonverbal cues they use in making this decision. The findings of this study, as well as future implications for studies, are discussed

Possible High-Redshift, Low-Luminosity AGN Activity in the Hubble Deep Field

In the Hubble Deep Field (HDF), twelve candidate sources of high-redshift (z > 3.5) AGN activity have been identified. The color selection criteria were established by passing spectra of selected quasars and Seyfert galaxies (appropriately redshifted and modified for "Lyman forest" absorption), as well as stars, observed normal and starburst galaxies, and galaxy models for various redshifts through the filters used for the HDF observations. The actual identification of AGN candidates also involved convolving a Laplacian-of-Gaussian filter with the HDF images, thereby removing relatively flat galactic backgrounds and leaving only the point-like components in the centers. Along with positions and colors, estimated redshifts and absolute magnitudes are reported, with the candidates falling toward the faint end of the AGN luminosity function. One candidate has been previously observed spectroscopically, with a measured redshift of 4.02. The number of sources reported here is consistent with a simple extrapolation of the observed quasar luminosity function to magnitude 30 in B_Johnson. Implications for ionization of the intergalactic medium and for gravitational lensing are discussed.Comment: 10 pages LaTex plus 2 separate files (Table 1 which is a two-page landscape LaTex file; and Figure 6 which is a large (0.7 MB) non-encapsulated postscript file).

A complete distribution of redshifts for sub-millimetre galaxies in the SCUBA-2 Cosmology Legacy Survey UDS field

This is a pre-copyedited, author-produced PDF of an article accepted for publication in Monthly Notices of the Royal Astronomical Society following peer review.

All rights reserved.Sub-milllimetre galaxies (SMGs) are some of the most luminous star-forming galaxies in the Universe, however their properties remain hard to determine due to the difficulty of identifying their optical\slash near-infrared counterparts. One of the key steps to determining the nature of SMGs is measuring a redshift distribution representative of the whole population. We do this by applying statistical techniques to a sample of 761 850$\mu$m sources from the SCUBA-2 Cosmology Legacy Survey observations of the UKIDSS Ultra-Deep Survey (UDS) Field. We detect excess galaxies around $> 98.4$ per cent of the 850$\mu$m positions in the deep UDS catalogue, giving us the first 850$\mu$m selected sample to have virtually complete optical\slash near-infrared redshift information. Under the reasonable assumption that the redshifts of the excess galaxies are representative of the SMGs themselves, we derive a median SMG redshift of $z = 2.05 \pm 0.03$, with 68 per cent of SMGs residing between $1.07Peer reviewedFinal Accepted Versio

Farmers' management of rice varietal diversity in the mid-hills of Nepal: implications for on-farm conservation and crop improvement

Season-long monitoring of on-farm rice (Oryza sativa, L.) plots in Nepal explored farmers' decision-making process on the deployment of varieties to agroecosystems, application of production inputs to varieties, agronomic practices and relationship between economic return and area planted per variety. Farmers deploy varieties [landraces (LRs) and modern varieties (MVs)] to agroecosystems based on their understanding of characteristics of varieties and agroecosystems, and the interaction between them. In marginal growing conditions, LRs can compete with MVs. Within an agroecosystem, economic return and area planted to varieties have positive relationship, but this is not so between agroecosystems. LRs are very diverse on agronomic and economic traits; therefore, they cannot be rejected a priori as inferior materials without proper evaluation. LRs have to be evaluated for useful traits and utilized in breeding programmes to generate farmer-preferred materials for marginal environments and for their conservation on-farm

Consumers and Their Celebrity Brands: How Personal Narratives Set the Stage for Attachment

This research demonstrates how consumer attachment to celebrity brands is driven by perceived narratives about the celebrity’s persona, which triggers communal (i.e., altruistic) relationship norms. The research investigates the differential role of narratives about celebrities’ personal vs. professional lives in creating attachment, and identifies and tests moderating effects of narrative characteristics including perceived source of fame, valence and authenticity. Design/methodology/approach – Three online experiments tested the proposed direct, mediating, and moderating relationships. Data was analyzed using mediation analysis and multiple ANOVAs. Findings – Results suggest relationship norms that are more altruistic in nature fully mediate the relationship between narrative type and brand attachment. Additionally, personal narratives produce stronger attachment than professional narratives; the celebrity’s source of fame moderates narrative type and attachment; and on-brand narratives elicit higher attachment than off-brand narratives, even when these narratives are negative. Practical implications – We offer recommendations for how marketers can shape celebrity brand narratives to build stronger consumer attachment. Notably, personal (vs. professional) narratives are critical in building attachment, especially for celebrity brands that are perceived to have achieved their fame. Both positive and negative personal narratives can strengthen attachment for achieved celebrity brands, but only if they are on-brand with consumer expectations. Originality/value – This research is an introductory examination of the fundamental theoretical process by which celebrity brand relationships develop from brand persona narratives, and how characteristics of those narratives influence consumer-brand attachment
