Not Shut in by Any Fence

From their beginning in the mid-l 800s, zoos ( or zoological gardens as they were first known) were meant for both research and education. They offered viewers the opportunity to see animals that they otherwise would never have seen. These animals were kept in cages to protect the zoo-goers. The history of zoos demonstrates a conflicting desire between our human need to connect with animals as well as our fear (literal and metaphoric) of what that connection might mean. Informing this creative project are three main areas of research: primary research in the form of interview, place-based research conducted at the National Zoological Park in Washington, D.C. and Library of Congress, and literature specifically about zoos (including the history of the modern zoo). This thesis explores human connection to animals within zoos, the connections we have with ourselves, and the connections we have with animals in our past, present and future

Teaching students with behavioral disorders to use a negotiation procedure: Impact on classroom behavior and conflict resolution strategy

The impact of the instruction of a six-step problem solving negotiation procedure on the conflict resolution strategies and classroom behavior of six elementary students with challenging behaviors was examined. Moderately positive effects were found for the following negotiation strategies used by students: independent problem solving, problem solving requiring a teacher prompt, and avoiding. However, there were limited effects of the negotiation instruction on the students\u27 use of the negotiation strategy of forcing; and a negligible, negative effect was found on student problem solving negotiation requiring a prompt by a crisis interventionist. Similarly, there were limited effects of the instruction on students\u27 use of verbal and physical aggression. Findings indicated that the students with the most severe challenging behaviors benefited more from the instruction. All students were able to learn the problem solving negotiation procedure, though sometimes visual and verbal prompts were needed. Overall student and teacher attitudes toward the problem solving negotiation instruction were positive. These findings suggest that giving direct instruction of problem solving negotiation to students with challenging behaviors provides some pro-social benefits

Through a Smoother Lens: An expected absence of LCDM substructure detections from hydrodynamic and dark matter only simulations

A fundamental prediction of the cold dark matter cosmology is the existence of a large number of dark subhalos around galaxies, most of which should be entirely devoid of stars. Confirming the existence of dark substructures stands among the most important empirical challenges in modern cosmology: if they are found and quantified with the mass spectrum expected, then this would close the door on a vast array of competing theories. But in order for observational programs of this kind to reach fruition, we need robust predictions. Here we explore substructure predictions for lensing using galaxy lens-like hosts at z=0.2 from the Illustris simulations both in full hydrodynamics and dark matter only. We quantify substructures more massive than ~ 10^9 M_sun, comparable to current lensing detections derived from HST, Keck, and ALMA. The addition of full hydrodynamics reduces the overall subhalo mass function by about a factor of two. Even for the dark matter only runs, most (~ 85%) lines of sight through projected cylinders of size close to an Einstein radius contain no substructures larger than 10^9 M_sun. The fraction of empty sight lines rises to ~ 95% in full physics simulations. This suggests we will likely need hundreds of strong lensing systems suitable for substructure studies, as well as predictions that include the effects of baryon physics on substructure, to properly constrain cosmological models. Fortunately, the field is poised to fulfill these requirements.Comment: 11 pages, 9 figure

NHS Reforms and the Working Lives of Midwives and Physiotherapists

From 2000 the NHS was subjected to a series of far reaching reforms, the purposes of which were to increase the role of the primary care sector in commissioning and providing services, promote healthier life styles, reduce health inequality, and improve service standards. These were seen as requiring a greater leadership role from health professionals, closer and more cooperative working between health professionals, and between health professionals, social services, and community and other service providers. The project surveyed a random sample of midwives and physiotherapists to investigate their perceptions of the effectiveness of the reforms, and their effects on working lives. The predominant perception was that NHS reforms had negatively affected the funding of their services; and had done little to improve service quality, delivery or organisation. Although the potential existed for the reforms to improve services, the necessary resources and required staffing were not made available and the objectives of the reforms were only partially secured by intensifying of work. The downside of this was a deterioration of the socio-psychological wellbeing of midwives and physiotherapists, especially the former, exacerbating the shortage of skilled and experienced. Shortage of staff and the associated increased work burdens were demoralising and demotivating; morale and job satisfaction declined, and job insecurity and labour turnover increased.Professional work, midwives, physiotherapists, Britain, public sector reforms, job satisfaction and morale

Cultural connections: The Role of the Arts and Humanities in Competitiveness and Local Development

This report considers how the arts and cultural institutions contribute to the appeal of place. Cultural institutions are a prominent part of UK society – and many have a rich and long heritage. The impact of such institutions has often been evaluated in terms of engagement and participation or on the direct economic impact of cultural institutions. This study primarily focuses on the wider role of cultural institutions in their local economies; their innovative activities; how they connect to other local organisations such as universities; and how they collaborate with academics from the Arts and Humanities

The Universal Stellar Mass-Stellar Metallicity Relation for Dwarf Galaxies

We present spectroscopic metallicities of individual stars in seven gas-rich dwarf irregular galaxies (dIrrs), and we show that dIrrs obey the same mass-metallicity relation as the dwarf spheroidal (dSph) satellites of both the Milky Way and M31: Z_* ∝ M_*^(0.30±0.02). The uniformity of the relation is in contradiction to previous estimates of metallicity based on photometry. This relationship is roughly continuous with the stellar mass-stellar metallicity relation for galaxies as massive as M_* = 10^(12) M_☉. Although the average metallicities of dwarf galaxies depend only on stellar mass, the shapes of their metallicity distributions depend on galaxy type. The metallicity distributions of dIrrs resemble simple, leaky box chemical evolution models, whereas dSphs require an additional parameter, such as gas accretion, to explain the shapes of their metallicity distributions. Furthermore, the metallicity distributions of the more luminous dSphs have sharp, metal-rich cut-offs that are consistent with the sudden truncation of star formation due to ram pressure stripping

The Role of Dwarf Galaxies in Building Large Stellar Halos

The hierarchical theory of galaxy formation rests on the idea that smaller galactic structures merge to form the galaxies that we see today. The past decade has provided remarkable observational support for this scenario, driven in part by advances in spectroscopic instrumentation. Multi-object spectroscopy enabled the discovery of kinematically cold substructures around the Milky Way and M31 that are likely the debris of disrupting satellites. Improvements in high-resolution spectroscopy have produced key evidence that the abundance patterns of the Milky Way halo and its dwarf satellites can be explained by Galactic chemical evolution models based on hierarchical assembly. These breakthroughs have depended almost entirely on observations of nearby stars in the Milky Way and luminous red giant stars in M31 and Local Group dwarf satellites. In the next decade, extremely large telescopes will allow observations far down the luminosity function in the known dwarf galaxies, and they will enable observations of individual stars far out in the Galactic halo. The chemical abundance census now available for the Milky Way will become possible for our nearest neighbor, M31. Velocity dispersion measurements now available in M31 will become possible for systems beyond the Local Group such as Sculptor and M81 Group galaxies. Detailed studies of a greater number of individual stars in a greater number of spiral galaxies and their satellites will test hierarchical assembly in new ways because dynamical and chemical evolution models predict different outcomes for halos of different masses in different environments.Comment: Astro2010 Decadal Survey White Paper, 8 page

Phonological Factors Affecting L1 Phonetic Realization of Proficient Polish Users of English

Acoustic phonetic studies examine the L1 of Polish speakers with professional level proficiency in English. The studies include two tasks, a production task carried out entirely in Polish and a phonetic code-switching task in which speakers insert target Polish words or phrases into an English carrier. Additionally, two phonetic parameters are studied: the oft-investigated VOT, as well as glottalization vs. sandhi linking of word-initial vowels. In monolingual Polish mode, L2 interference was observed for the VOT parameter, but not for sandhi linking. It is suggested that this discrepancy may be related to the differing phonological status of the two phonetic parameters. In the code-switching tasks, VOTs were on the whole more English-like than in monolingual mode, but this appeared to be a matter of individual performance. An increase in the rate of sandhi linking in the code-switches, except for the case of one speaker, appeared to be a function of accelerated production of L1 target items
