Exploring Amaranth’s Color Palette: Linking Phenotype, Plant Adaptation, and Human Health
Amaranthus is a genus containing species that are highly desirable, yet underutilized crops and species that are highly despised pernicious agricultural weeds. Cultivated species are primarily grown as nutritious pseudograins, colorful ornamentals, or leafy greens and are recognized for tolerance to heat, drought, and salinity. Weedy amaranths possess similar adaptive traits, in addition to evolved resistance to numerous herbicides, and pose severe challenges to global agriculture. Plant pigments (i.e., betalains, carotenoids) are central to understanding this impressive diversity of phenotypes and adaptive traits
Signatures of impact-driven atmospheric loss in large ensembles of exoplanets
The results of large-scale exoplanet transit surveys indicate that the
distribution of small planet radii is likely sculpted by atmospheric loss.
Several possible physical mechanisms exist for this loss of primordial
atmospheres, each of which produces a different set of observational
signatures. In this study, we investigate the impact-driven mode of atmosphere
loss via N-body simulations. We compare the results from giant impacts, at a
demographic level, to results from another commonly-invoked method of
atmosphere loss: photoevaporation. Applying two different loss prescriptions to
the same sets of planets, we then examine the resulting distributions of
planets with retained primordial atmospheres. As a result of this comparison,
we identify two new pathways toward discerning the dominant atmospheric loss
mechanism at work. Both of these pathways involve using transit multiplicity as
a diagnostic, in examining the results of follow-up atmospheric and radial
velocity surveys.Comment: 17 pages, 10 figures, Submitted to Ap
Strategy, intentionality, and impact: A purchasing plan for library promotional swag
The labor and expense involved in developing a comprehensive outreach program can be overwhelming. There are often additional expenditures for marketing and promotional items to support the outreach events that go beyond costs of planning
and staffing outreach activities. The Texas A&M University Libraries boast a robust outreach program—library employees participate in more than 100 outreach activities each calendar year. We developed programmatic strategies for improving
the cost and labor efficiency of both purchasing and managing the distribution of library-branded promotional items as a part of these outreach efforts. Colloquially, these items are known as swag. This chapter will provide insight into why and how we created a swag inventory system to support our outreach program
Decisions and the Evolution of Memory: Multiple Systems, Multiple Functions
Memory evolved to supply useful, timely information to the organism’s decision-making systems. Therefore, decision rules, multiple memory systems, and the search engines that link them should have coevolved to mesh in a coadapted, functionally interlocking way. This adaptationist perspective suggested the scope hypothesis: When a generalization is retrieved from semantic memory, episodic memories that are inconsistent with it should be retrieved in tandem to place boundary conditions on the
scope of the generalization. Using a priming paradigm and a decision task involving person memory, the authors tested and confirmed this hypothesis. The results support the view that priming is an evolved adaptation. They further show that dissociations between memory systems are not—and should not be—absolute: Independence exists for some tasks but not others

Socio-Emotional Functioning and Face Recognition Ability in the Normal Population
Recent research indicates face recognition ability varies within the normal population. To date, two factors have been identified that influence this cognitive process: the age and gender of the perceiver. In this paper, we examine the influence of socio-emotional functioning on face recognition ability. We invited participants with high and low levels of empathy (as indicated by the Empathy Quotient) to take part in a face recognition test. Participants were asked to study a set of faces, and at test viewed the studied faces intermixed with novel faces. As predicted, high empaths achieved higher scores in the face recognition test compared to low empaths. This pattern of findings provides further evidence that face recognition ability varies within the normal population, and suggests socio-emotional functioning may be an additional factor that influences face recognition ability
Searching for Inflow Towards Massive Starless Clump Candidates Identified in the Bolocam Galactic Plane Survey
Recent Galactic plane surveys of dust continuum emission at long wavelengths
have identified a population of dense, massive clumps with no evidence for
on-going star formation. These massive starless clump candidates are excellent
sites to search for the initial phases of massive star formation before the
feedback from massive star formation effects the clump. In this study, we
search for the spectroscopic signature of inflowing gas toward starless clumps,
some of which are massive enough to form a massive star. We observed 101
starless clump candidates identified in the Bolocam Galactic Plane Survey
(BGPS) in HCO+ J = 1-0 using the 12m Arizona Radio Observatory telescope. We
find a small blue excess of E = (Nblue - Nred)/Ntotal = 0.03 for the complete
survey. We identified 6 clumps that are good candidates for inflow motion and
used a radiative transfer model to calculate mass inflow rates that range from
500 - 2000 M /Myr. If the observed line profiles are indeed due to large-scale
inflow motions, then these clumps will typically double their mass on a free
fall time. Our survey finds that massive BGPS starless clump candidates with
inflow signatures in HCO+ J = 1-0 are rare throughout our Galaxy.Comment: 14 pages, 9 figure

SCOPE New Photographic Practices
The photographic practices brought together for this exhibition and publication provide a broad scope of how photographic and lens based media may be used in order to have a visceral and conceptual impact. The methods on show demonstrate the way that artists might pick and choose from the approaches, processes and debates that have arisen through the medium’s history. This collection of work features film, video and photography that demand a renegotiation of the relationship between camera, subject and viewer.
