Examining Implicit Person Theory and Feedback Environment in Undergraduate Research Relationships
This study examined the relationship between implicit person theory, our thoughts about malleability of human traits, and the trust students have for their faculty research advisor. There was no relationship between implicit person theory and trust. The faculty feedback environment was also captured to understand the day-to-day interactions of the student and their faculty research advisor. There was a significant relationship between a positive feedback environment and students\u27 intention to continue collaboration with the faculty member

Employee Green Behavior as the Core of Environmentally Sustainable Organizations
Environmental sustainability has become an ethical and strategic imperative for organizations, and more and more employees are interested, encouraged, or instructed to act in environmentally sustainable ways. Consequently, organizational scholars have increasingly studied individual-level antecedents of employee pro-environmental or employee green behavior (EGB). We argue that, to advance this literature and to inform effective interventions, research should investigate how EGB, as a compound performance domain, is associated with antecedents and consequences at multiple levels (i.e., individual, team, work context, organization, society). Accordingly, we pursue three interrelated goals with this review. We first present a comprehensive review of research on EGB, including definitions, theoretical frameworks, methodological approaches, and empirical findings. Second, we develop an integrative conceptual model of EGB as the core of organizational environmental sustainability. Third, we conclude with recommendations for future theory development and methodological improvements, as well as practical implications for employees, leaders, and human resource management
Research Software Engineers: Career Entry Points and Training Gaps
As software has become more essential to research across disciplines, and as
the recognition of this fact has grown, the importance of professionalizing the
development and maintenance of this software has also increased. The community
of software professionals who work on this software have come together under
the title Research Software Engineer (RSE) over the last decade. This has led
to the formalization of RSE roles and organized RSE groups in universities,
national labs, and industry. This, in turn, has created the need to understand
how RSEs come into this profession and into these groups, how to further
promote this career path to potential members, as well as the need to
understand what training gaps need to be filled for RSEs coming from different
entry points. We have categorized three main classifications of entry paths
into the RSE profession and identified key elements, both advantages and
disadvantages, that should be acknowledged and addressed by the broader
research community in order to attract and retain a talented and diverse pool
of future RSEs.Comment: Submitted to IEEE Computing in Science & Engineering (CiSE): Special

Tidal controls on the lithospheric thickness and topography of Io from magmatic segregation and volcanism modelling
Tidal heating is expected to impart significant, non-spherically-symmetric
structure to Jupiter's volcanic moon Io. A signature of spatially variable
tidal heating is generally sought in observations of surface heat fluxes or
volcanic activity, an exploration complicated by the transient nature of
volcanic events. The thickness of the lithosphere is expected to change over
much longer timescales, and so may provide a robust link between surface
observations and the tidal heating distribution. To predict long-wavelength
lithospheric thickness variations, we couple three-dimensional tidal heating
calculations to a suite of one-dimensional models of magmatic segregation and
volcanic eruption. We find that the lithospheric thickness could either be
correlated with the radially integrated heating rate, or weakly
anti-correlated. Lithospheric thickness is correlated with radially integrated
heating rate if magmatic intrusions form at a constant rate in the lithosphere,
but is weakly anti-correlated if intrusions form at a rate proportional to the
flux through volcanic conduits. Utilising a simple isostasy model we show how
variations in lithospheric thickness can predict long-wavelength topography.
The relationship between lithospheric thickness and topography depends on the
difference in chemical density between the lithosphere and mantle. Assuming
that this difference is small, we find that long-wavelength topography
anti-correlates with lithospheric thickness. These results will allow future
observations to critically evaluate models for Io's lithospheric structure, and
enable their use in constraining the distribution of tidal heating.Comment: Published in Icaru
Four-year experience with methotrexate exposures.
INTRODUCTION: Unintentional methotrexate (MTX) acute oral overdose is rarely reported.
METHODS: We conducted a retrospective chart review of all human exposure calls (\u3e150,000 charts) for MTX ingestions reported to our Poison Center during 2000-2003.
RESULTS: Thirteen patients met the criteria. The average amount of MTX ingested was 13.03 mg (data from 7 cases), and the average patient age was 43 years (20 months to 80 years). No significant toxicities occurred.
DISCUSSION: Although intravenous MTX toxicity can be severe, this does not appear to be a phenomenon associated with either acute unintentional or suicidal oral ingestion
Tidal Forcing in Icy‐Satellite Oceans Drives Mean Circulation and Ice‐Shell Torques
Tidal forces generate time‐varying currents in bodies with fluid layers, such as the icy ocean moons of the outer solar system. The expectation has been that tidal currents are periodic—they average to zero over a forcing period—so that they are not associated with a mean flow. This expectation arises from the assumption of linearity. Here, we relax this assumption and develop a theory that predicts the emergence of mean currents driven by any periodic forcing. The theory, derived in the context of a global, uniform, shallow ocean, constitutes a set of mean flow equations forced by non‐linear eddy fluctuations. The latter are the canonical, periodic tidal currents predicted by the Laplace Tidal equations. We show that the degree‐2 tide‐raising potential due to obliquity and/or orbital eccentricity can drive time‐averaged currents with zonal wavenumbers from 0 to 4. The most prominent of these is a retrograde zonal jet driven by the obliquity‐forcing potential. Assuming Cassini state obliquities, this jet has speeds ranging from 0.01 to 1 mm s−1, which can exert torques up to roughly 1015 N m at the ice–ocean interfaces of Europa, Callisto, Titan, and Triton. Depending on the viscosity of the ice shell, these torques could drive ice shell drift rates of tens to potentially hundreds of meters a year. Thinner or stably stratified global oceans can experience much faster mean currents
Elliptic curves over a finite field and the trace formula
We prove formulas for power moments for point counts of elliptic curves over
a finite field such that the groups of -points of the curves contain a
chosen subgroup. These formulas express the moments in terms of traces of Hecke
operators for certain congruence subgroups of
. As our main technical input we prove an
Eichler-Selberg trace formula for a family of congruence subgroups of
which include as special cases the groups
and . Our formulas generalize results of Birch and
Ihara (the case of the trivial subgroup, and the full modular group), and
previous work of the authors (the subgroups and
and congruence subgroups
). We use these formulas to answer statistical
questions about point counts for elliptic curves over a fixed finite field,
generalizing results of Vl\v{a}du\c{t}, Gekeler, Howe, and others.Comment: To appear in Proc. London Math. Soc. 61 page

Employee Green Behavior: A Meta-Analysis
Due to climate change, the need to protect biodiversity and reduce pollution, and governmental regulations, many organizations are aiming to become more environmentally sustainable. In this context, researchers and practitioners are increasingly interested in the construct of employee green behavior (EGB). EGB has been considered by numerous empirical studies over the last two decades and its associations with demographic characteristics, individual differences, workrelated perceptions, and job attitudes. To systematically synthesize the rapidly growing literature on EGB, we conducted a meta-analysis (k = 135 independent samples; total N = 47,442 employees). Results showed positive associations between EGB and, for example, proenvironmental attitudes, corporate social responsibility, and green psychological climate. We further report the results of a meta-analytic path model based on the theory of planned behavior, which showed that pro-environmental attitude, norms, perceived behavioral control, and intentions positively predicted EGB
