Attracting and Retaining Women in the Transportation Industry

This study synthesized previously conducted research and identified additional research needed to attract, promote, and retain women in the transportation industry. This study will detail major findings and subsequent recommendations, based on the annotated bibliography, of the current atmosphere and the most successful ways to attract and retain young women in the transportation industry in the future. Oftentimes, it is perception that drives women away from the transportation industry, as communal goals are not emphasized in transportation. Men are attracted to agentic goals, whereas women tend to be more attracted to communal goals (Diekman et al., 2011). While this misalignment of goals has been found to be one reason that women tend to avoid the transportation industry, there are ways to highlight the goal congruity processes that contribute to transportation engineering, planning, operations, maintenance, and decisions—thus attracting the most talented individuals, regardless of gender. Other literature has pointed to the lack of female role models and mentors as one reason that it is difficult to attract women to transportation (Dennehy & Dasgupta, 2017). It is encouraging to know that attention is being placed on the attraction and retention of women in all fields, as it will increase the probability that the best individual is attracted to the career that best fits their abilities, regardless of gender

Production of the D-wave bbˉb \bar b states

The first and second families of D-wave $b \bar b$ quarkonium states are expected to have masses near 10.16 and 10.44 GeV/$c^2$. The accuracy of these predictions is discussed, and the prospects of two methods for producing these states in electron-positron collisions are updated. Direct scans in the $e^+ e^-$ center-of-mass can give rise to the $^3D_1$ states. The $1^3D_J$ states have also been searched for in the electromagnetic cascades from \ups(3S) \to \gamma \chi'_b \to \gamma \gamma ^3D_J. The sample of \ups(3S) decays required to definitively observe the $1^3D_J$ states is found to be only somewhat greater than the present world's total.Comment: 7 pages, LaTeX, 1 figure, to be submitted to Phys.

Comment on Z′Z''s and the H1 and ZEUS High Q2Q^2 Anomalies

We investigate the effects of extra neutral gauge bosons on the high $Q^2$ region of the $e^+p \to e^+ X$ cross section at $\sqrt{s}=300$ GeV. We found that the only models with electroweak strength coupling, typical of extended gauge theories, that give a better fit to the H1 and ZEUS high $Q^2$ data than the standard model, are ruled out by existing data from the Tevatron. From general scaling arguments, using the allowed contact interactions, the only allowed models with $Z'$'s would be those with strong couplings although even in this case the statistical evidence is not compelling.Comment: Latex file uses revtex version 3, epsfig, 1 postscript figure is attache

Discovery Potential for New Phenomena

We examine the ability of future facilities to discover and interpret non-supersymmetric new phenomena. We first explore explicit manifestations of new physics, including extended gauge sectors, leptoquarks, exotic fermions, and technicolor models. We then take a more general approach where new physics only reveals itself through the existence of effective interactions at lower energy scales. [Summary Report of the New Phenomena Working Group.

On the population of remnant FRII radio galaxies and implications for radio source dynamics

The purpose of this work is two-fold: (1) to quantify the occurrence of ultra-steep spectrum remnant FRII radio galaxies in a 74 MHz flux limited sample, and (2) perform Monte-Carlo simulations of the population of active and remnant FRII radio galaxies to confront models of remnant lobe evolution, and provide guidance for further investigation of remnant radio galaxies. We find that fewer than 2$\%$ of FRII radio galaxies with S$_{ \rm74~MHz} > 1.5$ Jy are candidate ultra-steep spectrum remnants, where we define ultra-steep spectrum as $\alpha_{\rm 74~MHz}^{\rm 1400~MHz} > 1.2$. Our Monte-Carlo simulations demonstrate that models involving Sedov-like expansion in the remnant phase, resulting in rapid adiabatic energy losses, are consistent with this upper limit, and predict the existence of nearly twice as many remnants with normal (not ultra-steep) spectra in the observed frequency range as there are ultra-steep spectrum remnants. This model also predicts an ultra-steep remnant fraction approaching 10$\%$ at redshifts $z < 0.5$. Importantly, this model implies the lobes remain over-pressured with respect to the ambient medium well after their active lifetime, in contrast with existing observational evidence that many FRII radio galaxy lobes reach pressure equilibrium with the external medium whilst still in the active phase. The predicted age distribution of remnants is a steeply decreasing function of age. In other words young remnants are expected to be much more common than old remnants in flux limited samples. For this reason, incorporating higher frequency data $\gtrsim 5$ GHz will be of great benefit to future studies of the remnant population.Comment: 19 pages, 8 figures, 4 table

Properties of the Charmed P-wave Mesons

Two broad charmed mesons, the D_0^* and D_1', have recently been observed. We examine the quark model predictions for the D_0^* and D_1' properties and discuss experimental measurements that can shed light on them. We find that these states are well described as the broad, j=1/2 non-strange charmed P-wave mesons. Understanding the D_0^* and D_1' states can provide important insights into the D_{sJ}^*(2317), D_{sJ}(2460) states whose unexpected properties have led to renewed interest in hadron spectroscopy.Comment: 7 pages.
