Developing an inter-university partnership: The importance of relationally-connected leaders
We have been involved in an inter-university partnership that supports, contributes to, and influences our own and others’ thinking and actions. As we have collaborated on teaching, learning, and research in the field of educational leadership, we recognise that we have developed our own leadership practice and created opportunities for others to do so. The partnership in which academics and students from the University of Central Oklahoma and the University of Waikato have been participating has evolved as a flexible and innovative endeavor over an eighteen month period. In this relatively brief time, we have discovered there are considerable possibilities for the partnership to be developed in a number of ways that will benefit academics, students, and our respective institutions. In this paper, we examine and discuss the findings generated by our initial inquiry as we seek to make sense of our inter university partnership in order to sustain and progress it. Our leadership during the initial phases of the partnership appears to have been a key element in its success. We have found that the presence of a relational connectedness has influenced and enhanced our own leadership practice and subsequently the quality of the partnership. It has enabled us to facilitate the growth of a community of practice and generate academic collaboration
Quasar feedback and the origin of radio emission in radio-quiet quasars
We conduct kinematic analysis of the SDSS spectra of 568 obscured luminous
quasars, with the emphasis on the kinematic structure of the [OIII]5007
emission line. [OIII] emission tends to show blueshifts and blue excess, which
indicates that at least part of the narrow-line gas is undergoing an organized
outflow. The velocity width containing 90% of line power ranges from 370 to
4780 km/sec, suggesting outflow velocities up to 2000 km/sec. The velocity
width of the [OIII] emission is positively correlated with the radio luminosity
among the radio-quiet quasars. We propose that radio emission in radio-quiet
quasars is due to relativistic particles accelerated in the shocks within the
quasar-driven outflows; star formation in quasar hosts is insufficient to
explain the observed radio emission. The median radio luminosity of the sample
of nu L_nu[1.4GHz] = 10^40 erg/sec suggests a median kinetic luminosity of the
quasar-driven wind of L_wind=3x10^44 erg/sec, or about 4% of the estimated
median bolometric luminosity L_bol=8x10^45 erg/sec. Furthermore, the velocity
width of [OIII] is positively correlated with mid-infrared luminosity, which
suggests that outflows are ultimately driven by the radiative output of the
quasar. As the outflow velocity increases, some emission lines characteristic
of shocks in quasi-neutral medium increase as well, which we take as further
evidence of quasar-driven winds propagating into the interstellar medium of the
host galaxy. None of the kinematic components show correlations with the
stellar velocity dispersions of the host galaxies, so there is no evidence that
any of the gas in the narrow-line region of quasars is in dynamical equilibrium
with the host galaxy. Quasar feedback appears to operate above the threshold
luminosity of L_bol=3x10^45 erg/sec.Comment: 23 pages, accepted to MNRA

Dialoging A Successful Pedagogy for Embedded Tutors
Over the past three years, Rider University’s Student Success Center Writing Lab has implemented an embedded tutor program for composition courses. Tutors attend class, participate in class discussions, facilitate writing workshops in class, and hold drop-in hours for students (in addition to tutors’ Writing Lab hours). The Embedded Tutor (ET) program, facilitated by Jenny Scudder (who is also the Writing Lab Director), has been successful in helping students complete skills-based courses and connect to academic support services. Initial assessment of the ET program supports the inclusion of the tutor in a skills-based course. While an ET’s training is similar to a tutor who works solely in the Writing Lab, there are key additions that are vital to the tutors’—and the program’s—succesUniversity Writing Cente
Similarity of ionized gas nebulae around unobscured and obscured quasars
Quasar feedback is suspected to play a key role in the evolution of massive
galaxies, by removing or reheating gas in quasar host galaxies and thus
limiting the amount of star formation. In this paper we continue our
investigation of quasar-driven winds on galaxy-wide scales. We conduct Gemini
Integral Field Unit spectroscopy of a sample of luminous unobscured (type 1)
quasars, to determine the morphology and kinematics of ionized gas around these
objects, predominantly via observations of the [O III]5007 emission line. We
find that ionized gas nebulae extend out to ~13 kpc from the quasar, that they
are smooth and round, and that their kinematics are inconsistent with gas in
dynamical equilibrium with the host galaxy. The observed morphological and
kinematic properties are strikingly similar to those of ionized gas around
obscured (type 2) quasars with matched [O III] luminosity, with marginal
evidence that nebulae around unobscured quasars are slightly more compact.
Therefore in samples of obscured and unobscured quasars carefully matched in [O
III] luminosity we find support for the standard geometry-based unification
model of active galactic nuclei, in that the intrinsic properties of quasars,
of their hosts and of their ionized gas appear to be very similar. Given the
apparent ubiquity of extended ionized regions, we are forced to conclude that
either the quasar is at least partially illuminating pre-existing gas or that
both samples of quasars are seen during advanced stages of quasar feedback. In
the latter case, we may be biased by our [O III]-based selection against
quasars in the early "blow-out" phase, for example due to dust obscuration.Comment: 17 pages, 10 figures, 2 tables. Published in MNRAS, 201

This brief report provides findings from data collected in year 2 of a survey of teenagers' views and experiences of sex and relationships education and sexual health services in Kent. The data in year 2 was collected in Autumn 2005, a year after the data collected in year 1. The purpose of this report is to highlight the results in year 2 which differ from the year 1 survey data. It is to be used in conjunction with the report in year 1 entitled "Service Development Programme: Maximising Life Opportunies for Teenagers: Teenagers' Views and Experiences of Sex and Relationships Educatioon, Sexual Health Services and Family Suupport Services in Kent: Survey Findings July 2005". The final report on the survey will consist of findings from further analysis of the data from year 1 and year 2 merged together, available at the end of 2006
Sizes and Kinematics of Extended Narrow-Line Regions in Luminous Obscured AGN Selected by Broadband Images
To study the impact of active galactic nuclei (AGN) feedback on the galactic
ISM, we present Magellan long-slit spectroscopy of 12 luminous nearby type 2
AGN (L_bol~10^{45.0-46.5} erg/s, z~0.1). These objects are selected from a
parent sample of spectroscopically identified AGN to have high
[OIII]{\lambda}5007 and WISE mid-IR luminosities and extended emission in the
SDSS r-band images, suggesting the presence of extended [OIII]{\lambda}5007
emission. We find spatially resolved [OIII] emission (2-35 kpc from the
nucleus) in 8 out of 12 of these objects. Combined with samples of higher
luminosity type 2 AGN, we confirm that the size of the narrow-line region
(R_NLR) scales with the mid-IR luminosity until the relation flattens at ~10
kpc. Nine out of 12 objects in our sample have regions with broad [OIII]
linewidths (w_80>600 km/s), indicating outflows. We define these regions as the
kinematically-disturbed region (KDR). The size of the KDR (R_KDR) is typically
smaller than R_NLR by few kpc but also correlates strongly with the AGN mid-IR
luminosity. Given the unknown density in the gas, we derive a wide range in the
energy efficiency {\eta}=dot{E}/L_bol=0.01%-30%. We find no evidence for an AGN
luminosity threshold below which outflows are not launched. To explain the
sizes, velocity profiles, and high occurrence rates of the outflows in the most
luminous AGN, we propose a scenario in which energy-conserving outflows are
driven by AGN episodes with ~10^8-year durations. Within each episode the AGN
flickers on shorter timescales, with a cadence of ~10^6 year active phases
separated by ~10^7 years.Comment: 32 pages, 21 figures, ApJ in revie
