Secondary School Counselors’ Perceptions of Service-Learning: Gaps between State Policy, Counselors’ Knowledge, and Implementation

The purpose of this study was a state-level investigation of school counselors’ knowledge of their role in the implementation of service-learning policy using survey research methods. The respondents reported having little knowledge of the policy, not having implemented it statewide, and not having been trained in service-learning pedagogy. Based on these results, this article provides implications for consideration when states develop educational policies that impact school counselors’ work

The Australia Telescope 20 GHz Survey: The Source Catalogue

We present the full source catalogue from the Australia Telescope 20 GHz (AT20G) Survey. The AT20G is a blind radio survey carried out at 20 GHz with the Australia Telescope Compact Array (ATCA) from 2004 to 2008, and covers the whole sky south of declination 0 deg. The AT20G source catalogue presented here is an order of magnitude larger than any previous catalogue of high-frequency radio sources, and includes 5890 sources above a 20 GHz flux-density limit of 40 mJy. All AT20G sources have total intensity and polarisation measured at 20 GHz, and most sources south of declination -15 deg also have near-simultaneous flux-density measurements at 5 and 8 GHz. A total of 1559 sources were detected in polarised total intensity at one or more of the three frequencies. We detect a small but significant population of non-thermal sources that are either undetected or have only weak detections in low-frequency catalogues. We introduce the term Ultra-Inverted Spectrum (UIS) to describe these radio sources, which have a spectral index alpha(5, 20) > +0.7 and which constitute roughly 1.2 per cent of the AT20G sample. The 20 GHz flux densities measured for the strongest AT20G sources are in excellent agreement with the WMAP 5-year source catalogue of Wright et al. (2009), and we find that the WMAP source catalogue is close to complete for sources stronger than 1.5 Jy at 23 GHz.Comment: 21 pages, accepted for publication in MNRA

Review of \u3ci\u3eThe Frontier in American Culture: An Exhibition at the Newberry Library, August 26,1994- January 7,1995\u3c/i\u3e Essays by Richard White and Patricia Nelson Limerick

The term frontier elicits many different meanings and interpretations among scholars and the American public, as do Buffalo Bill Cody\u27s Wild West show and Frederick Jackson Turner\u27s frontier thesis. Patricia Nelson Limerick and Richard White address these topics and try to appreciate their influence in American history and culture. With the help of artifacts from the Newberry Library, Limerick and White reveal how attitudes toward the old American West developed and how we understand that time and place today. In Frederick] ackson Turner and Buffalo Bill, White argues that both men\u27s visions of the American West are equally important to our understanding of historical conceptions of the frontier. White embellishes his thesis with meaningful documents, sketches, and paintings in an appealing manner. His inclusion of a Native American perspective adds breadth to his analysis of frontier historiography. Patricia Nelson Limerick\u27s The Adventures of the Frontier in the Twentieth Century takes a different, more eclectic approach, discussing everything from Velcro to Disneyland to characterize how images of the frontier invaded the American consciousness. Limerick is particularly convincing in showing how the definition of the word frontier has evolved over time and suggesting what it may come to mean in the future. The essay\u27s wit and creative use of familiar American images help to emphasize how the term frontier permeates American culture. And in placing her interpretation of the American frontier within the framework of the twentieth century, Limerick offers her readers a unique, imaginative perspective on Western history. Both White and Limerick provide uncommon views into the complexities of interpreting the American frontier. While shedding light on the impact of Buffalo Bill and Frederick J ackson Turner, they enrich our historical understanding of the American frontier

Productivity and Publishing: Writing Processes for New Scholars and Researchers

Productivity and Publishing: Writing Processes for New Scholars & Researchers by Margaret-Mary Sulentic Dowell, Leah Katherine Saal, Cynthia F. DiCarlo, and Tynisha D. Willingham takes the challenges and confusion out of academic writing and journal publishing by empowering readers to find the writing process that works for them. Activities and writing exercises help readers determine their research agendas, set realistic writing goals, , and follow time-tested and editor-approved processes for writing and revising journal articles. Topics cover the writing and publishing process from start to finish, addressing common issues for new academics like avoiding the blank page, selecting an appropriate journal, dealing with reviews, and leveraging your research into multiple articles and a comprehensive research agenda. Experts weigh in on crucial topics such as scholarly metrics and exposure and offer a journal editor\u27s perspective on the writing and publishing process.

The ATLAS(3D) project - VII. A new look at the morphology of nearby galaxies: the kinematic morphology-density relation

The definitive version can be found at: http://onlinelibrary.wiley.com/ Copyright Royal Astronomical SocietyIn Paper I of this series we introduced a volume-limited parent sample of 871 galaxies from which we extracted the ATLAS(3D) sample of 260 early-type galaxies (ETGs). In Papers II and III we classified the ETGs using their stellar kinematics, in a way that is nearly insensitive to the projection effects, and we separated them into fast and slow rotators. Here we look at galaxy morphology and note that the edge-on fast rotators generally are lenticular galaxies. They appear like spiral galaxies with the gas and dust removed, and in some cases are flat ellipticals (E5 or flatter) with discy isophotes. Fast rotators are often barred and span the same full range of bulge fractions as spiral galaxies. The slow rotators are rounder (E4 or rounder, except for counter-rotating discs) and are generally consistent with being genuine, namely spheroidal-like, elliptical galaxies. We propose a revision to the tuning-fork diagram by Hubble as it gives a misleading description of ETGs by ignoring the large variation in the bulge sizes of fast rotators. Motivated by the fact that only one third (34 per cent) of the ellipticals in our sample are slow rotators, we study for the first time the kinematic morphology-density T-Sigma relation using fast and slow rotators to replace lenticulars and ellipticals. We find that our relation is cleaner than using classic morphology. Slow rotators are nearly absent at the lowest density environments [f(SR) less than or similar to 2 per cent] and generally constitute a small fraction [f (SR) approximate to 4 per cent] of the total galaxy population in the relatively low-density environments explored by our survey, with the exception of the densest core of the Virgo cluster [f(SR) approximate to 20 per cent]. This contrasts with the classic studies that invariably find significant fractions of (misclassified) ellipticals down to the lowest environmental densities. We find a clean log-linear relation between the fraction f(Sp) of spiral galaxies and the local galaxy surface density Sigma(3), within a cylinder enclosing the three nearest galaxies. This holds for nearly four orders of magnitude in the surface density down to Sigma(3) approximate to 0.01 Mpc(-2), with f(Sp) decreasing by 10 per cent per dex in Sigma(3), while f(FR) correspondingly increases. The existence of a smooth kinematic T-Sigma relation in the field excludes processes related to the cluster environment, like e.g. ram-pressure stripping, as main contributors to the apparent conversion of spirals into fast rotators in low-density environments. It shows that the segregation is driven by local effects at the small-group scale. This is supported by the relation becoming shallower when using a surface density estimator Sigma(10) with a cluster scale. Only at the largest densities in the Virgo core does the f(Sp) relation break down and steepen sharply, while the fraction of slow rotators starts to significantly increase. This suggests that a different mechanism is at work there, possibly related to the stripping of the gas from spirals by the hot intergalactic medium in the cluster core and the corresponding lack of cold accretion.Peer reviewe
