Adults of both sexes and the previously unknown eggs of the parasitoid conopid fly Stylogaster neglecta Williston are illustrated and measurements are provided, including the total clutch size and the lengths and widths of eggs from random samples
Retrofitting O'Raifeartaigh Models with Dynamical Scales
We provide a method for obtaining simple models of supersymmetry breaking,
with all small mass scales generated dynamically, and illustrate it with
explicit examples. We start from models of perturbative supersymmetry breaking,
such as O'Raifeartaigh and Fayet models, that would respect an symmetry if
their small input parameters transformed as the superpotential does. By
coupling the system to a pure supersymmetric Yang-Mills theory (or a more
general supersymmetric gauge theory with dynamically small vacuum expectation
values), these parameters are replaced by powers of its dynamical scale in a
way that is naturally enforced by the symmetry. We show that supersymmetry
breaking in these models may be straightforwardly mediated to the
supersymmetric Standard Model, obtain complete models of direct gauge
mediation, and comment on related model building strategies that arise in this
simple framework.Comment: 15 pages, harvmac bi
The Quiet Leader
Leaders are thought to be the ones who are bold, do big things, and make big changes. We have made leaders into individuals who âchange the worldâ (Dudley, 2010). The reality is that there are leaders who do not live to have their names in the headlines or seek to do extraordinary, heroic acts. They are those who live in our community with humility. They impact the lives of others by being themselves, fulfilling the task at hand, and showing respect to others. In the field of sign language interpreting, Marian Lage is a leader
Interpreter educators in the United States: Teaching, research, and practice
In this thesis, the teaching, research, and practice of signed language interpreter educators in the United States is examined through a Critical Social Theory framework.
While there is literature on interpreter educators from the perspective of program directors, very little research has been done that gathers data directly from interpreter educators. The research available leads to recommendations for instructor credentials and qualifications; however, no data exists regarding current signed language interpreter educators and whether they possess the recommended criteria.
An exploratory survey was disseminated to interpreter educators in the United States to elicit information regarding their experience as signed language interpreters, as teachers, and regarding their engagement in research. Demographic information was collected to better understand how a participantâs social identity may affect program outcomes. The charts and diagrams in this study provide a broad overview of current interpreter educators, curriculum utilization, professional development, and research. The data from the survey was compared with the existing literature to assess for alignment, incongruences, and gaps.
The conclusion and results from critiquing the research and the findings show there are many additional areas for research regarding interpreter educators. The results also show the need for established hiring requirements for interpreter educators, peer-reviewed course materials, effective professional development for current instructors, and an increased engagement in conducting and disseminating research. It is the recommendation that educators and researchers engage in a critical self-assessment to understand the impact of interpreter educators on program outcomes
Latent consequences of early-life lead (Pb) exposure and the future: Addressing the Pb crisis
Background. The lead (Pb) exposure crisis in Flint, Michigan has passed from well-publicized event to a footnote, while its biological and social impact will linger for lifetimes. Interest in the âwater crisisâ has dropped to pre-event levels, which is neither appropriate nor safe. Flintâs exposure was severe, but it was not unique. Problematic Pb levels have also been found in schools and daycares in 42 states in the USA. The enormity of Pb exposure via municipal water systems requires multiple responses. Herein, we focus on addressing a possible answer to long-term sequelae of Pb exposure. We propose â4Râsâ (remediation, renovation, reallocation, and research) against the Pb crisis that goes beyond a short-term fix. Remediation for affected individuals must continue to provide clean water and deal with both short and long-term effects of Pb exposure. Renovation of current water delivery systems, at both system-wide and individual site levels, is necessary. Reallocation of resources is needed to ensure these two responses occur and to get communities ready for potential sequelae of Pb exposure. Finally, properly focused research can track exposed individuals and illuminate latent (presumably epigenetic) results of Pb exposure and inform further resource reallocation.
Conclusion. Motivation to act by not only the general public but also by scientific and medical leaders must be maintained beyond initial news cycle spikes and an annual follow-up story. Environmental impact of Pb contamination of drinking water goes beyond one exposure incident in an impoverished and forgotten Michigan city. Population effects must be addressed long-term and nationwide
The nature of the absorbing torus in compact Radio Galaxies
We present BeppoSAX observations of the two radio galaxies PKS 1934-63 and S5
1946+708. Strong Iron Kalpha lines are detected in both objects indicating that
the two sources are absorbed by column densities higher than 10^24 cm^(-2).
Combining radio continuum, HI absorption and X-ray data we can constrain the
physical state and the dimensions of the absorber. We find that the putative
obscuring torus is molecular and located at a distance higher than 20 pc from
the center in S5 1946+70. In PKS 1934-63 no radio nucleus has been observed. If
this is due to free-free absorption a radius of only a few pc is inferred.
Since the Kalpha lines have been detected only at 90% confidence, we also
discuss the implications if they would be not as strong as found from our data.
From our results it appears that the combination of hard X-ray data and
spatially resolved HI absorption measurements provides a powerful diagnostic
for conditions in the absorbing ``torus''.Comment: 8 pages, 5 figures, accepted for publication in Astronomy &

EMPLOYEE COMPENSATION AND JOB SATISFACTION ON DAIRY FARMS IN THE NORTHEAST
Economies of size have translated into much larger herd sizes and, therefore, employee bases on dairy farms throughout the Northeast. These non-family employees present managerial issues many farm managers are not accustomed to. This research quantifies and illustrates the internal pay structure and enumerates that current employee satisfaction levels present on the farms of members of the Northeast Dairy Producers Association (NEDPA).Human Resource Management, Compensation, Satisfaction, Labor and Human Capital,
