The Effects of Labyrinth Walking in an Academic Library
No full textThe purpose of this study was to determine if labyrinth walking in an academic library would reduce library user stress and promote relaxation. A non- equivalent control group design was employed. Systolic blood pressure was significant for time effect (effect size of .136, and power .721). Pulse rate was significant for time effect (effect size 0.93, and power .507). Satisfaction survey results demonstrated increased satisfaction after labyrinth walking. Data from this pilot will form the basis of a larger scale study to determine the effect of labyrinth walking on stress particularly in high-stress learning environments.Peer reviewe
An inclusive comprehensive educational program in the urban renewal area of Queensgate II in Cincinnati, Ohio., 1970
No full textThe following proposal, entitled An Inclusive Comprehen-sive Educational Program In the Urban Renewal Area of Queensgate II In Cincinnati, Ohio is submitted to the Neighborhood Programs Division, Renewal Assistance Administration in Washington, D.C. The chief investigator and writer is Janet M. Evans. This pro-ject is designed for one year and $134,475.90 is requested to fund it. There will be fourteen full-time professional staff members, eleven part-time professionals and one clerical staff member. The project will begin June 1970 and end on May 1971. This project is designed to provide an inclusive, comprehensive educational program for Queensgate II that will include pre-preparation of people for urban renewal, involvement in decision-making for their neighborhood, education, social ser-vices and preparation for redevelopment. It will be a practical and educational program in that it will determine, institute and render the necessary social services to the residents. It will provide special services for problem situations such as alcoholism; services to the elderly and to youth. The educational program will prepare leader-workers, and will provide transitional preparation for residents that will help them to use and care for new surroundings. The project is so designed as to provide opportunity for the consumers to take an active part in the planning and implementation of the education and services. It is hoped that the effective implementation of the project will provide a body of knowledge whereby other cities and urban renewal areas might benefit. It is also hoped it will prove that given an active part in the destiny of their lives, residents may become effective and contributing citizens in their local community and nation. The project is worthy of funding because it proposes to involve residents in an inclusive educational program, in needed services and their use, home-making, creating pride and reducing dependency. The elimination of dependency will reduce the financial burden to cities; and lastly, it will eliminate the "modern slums.
Factors Affecting pH Establishment and Maintenance in Peat Moss-Based Substrates
No full textProblems of inconsistent initial pH in peat moss substrates created using standard formulas for agricultural limestone additions, and substrate pH drift from the initial target may result from variations in the neutralization capacity of limestone and in the neutralization requirement of peat moss. This research was conducted to evaluate physical and chemical properties of limestone that may influence neutralization capacity, and properties of peat moss that may influence neutralization requirement. Limestones from twenty North American quarries were wet-sieved into eight particle diameter fractions (600 to < 38 μm). Specific surface of limestone particles was measured for each fraction. Reaction times were determined on three limestone particle size fractions. Particle size distribution, CaCO₃ and MgCO₃ contents, internal porosity, hardness, soundness, specific gravity, and specific surface were analyzed in multiple regressions with particle size included and also held constant at three size fractions to evaluate effects on limestone neutralization capacity. Peat moss samples were selected from Alberta, Canada bogs to represent the maximum range of species composition and the decomposition range (H1.5 to H4.0) used for commercial horticulture. Peat moss cation exchange capacity, base and iron saturation, inherent pH, buffer capacity and neutralization requirement were measured. These properties were analyzed in a multiple regression along with species composition, degree of decomposition, and detritus to determine effects on peat moss neutralization requirement. Limestones differed significantly in specific surface for each particle diameter fraction and in reaction times. There were significant variations in cation exchange capacity, base saturation, inherent pH, buffer capacity and neutralization requirement of peat mosses. Neutralization requirement was negatively correlated with base saturation, inherent pH, decomposition, [Fe²⁺], and sedge; and was positively correlated with S. angustifolium. Sphagnum species influenced cation exchange capacity, base saturation, and inherent pH. Inherent pH was most influenced by base saturation. Peat moss samples containing large amounts of S. fuscum had high cation exchange capacity and base saturation, and low degrees of decomposition. Adding specific surface measurements to those of particle size distribution and CaCO₃ content will further characterize limestone neutralization capacity; however, the problem of inconsistent initial pH can be better managed by understanding the inherent pH and base saturation of the peat mosses in the substrate. The problem of pH drift from the target can be controlled by ensuring an adequate amount of S. fuscum in the substrate
Cultural wealth and diaspora despair: Janet Frame’s In the Memorial Room
No full textJanet Frame came into uneasy collision with the ghost of Katherine Mansfield, the ‘godmother of New Zealand literature’, when she was awarded the Winn Manson Menton Fellowship in 1974. This, New Zealand’s only overseas literary fellowship, took her to Menton and the ‘Memorial Room’ of Villa Isola Bella in Menton, in comemmoration of Mansfield’s own stay there in 1920 and 1921. In In the Memorial Room, the novel written during this time and published posthumously, the writer in the public space of diaspora is undermined by competing demands and expectations. Frame’s protagonist is alienated, at odds with the local expatriate community, and disoriented, descending into a crisis of despair and creative impasse. This paper examines the novel’s narrative strategies of analysis, denial (of self and others) and repositioning, as the author figure suffers sensory deprivation (being blind, then deaf), writing becomes a burden, and language a hazard. The question of posthumous fame and the ‘anxiety of influence’, it suggests, are possible, but not unique, explanations for this complex response to the cultural wealth that Mansfield represents and which the Fellowship celebrated
Understanding young people's transitions in university halls through space and time
No full textThis article contributes to the theoretical discussion about young people's transitions through space and time. Space and time are complex overarching concepts that have creative potential in deepening understanding of transition. The focus of this research is young people's experiences of communal living in university halls. It is argued that particular space-time concepts draw attention to different facets of experience and in combination deepen the understanding of young people's individual and collective transitions. The focus of the article is the uses of the space-time concepts 'routine', 'representation', 'rhythm' and 'ritual' to research young people's experiences. The article draws on research findings from two studies in the North of England. © 2010 SAGE Publications
Sterile neutrino searches at the Icecube Neutrino Observatory
No full textThesis: Sc. D., Massachusetts Institute of Technology, Department of Physics, 2020"The following pages, 92-94, were not included in the original document submitted to the MIT Libraries. This is the most complete copy available"--Disclaimer page. Cataloged from PDF version of thesis. Supervised by Janet M. Conrad.Includes bibliographical references (pages 217-239).The IceCube Neutrino Observatory is capable of performing a unique search for sterile neutrinos through the exploitation of a matter enhanced resonant neutrino oscillation phenomena. As atmospheric muon neutrinos pass the dense material within the Earth, neutral current elastic forward scattering is predicted to induce a transition into a sterile state. This thesis presents two 3+1 sterile neutrino analyses by searching for spectral differences in the reconstructed energy and zenith direction of muon neutrino events, indicative of a transition into a sterile state. The first search probes the parameter space [delta]m²₄₁ and sin²(2[theta]₂₄) with relevant sensitivity to the global best fit region for a 3+1 sterile neutrino hypothesis. The second search performs a scan through sin²(2[theta]₂₄) and sin²([theta]₃₄) in the oscillation averaged out region of high-[delta]m²₄₁ ([theta]²₄₁ >~ 10 eV²). The analyses are performed using an improved event selection, which was found to extract 305,891 well reconstructed muon neutrino events with a sample purity above 99.9%, from eight years of IceCube data. Novel simulation techniques, along with updated calibration, and a re-assessment of the systematic uncertainties are also discussed. The first analysis finds a best fit sterile hypothesis point at [theta]²₄₁ = 4.47eV² and sin²([theta]₂₄ = 0.10, consistent with the no-sterile hypothesis at the 8% confidence level. The second analysis finds a best fit sterile hypothesis at sin²([theta]₃₄ = 0.40, sin²([theta]₃₄ =0.006, consistent with the null hypothesis at the 19% confidence level.by Spencer Nicholas Gaelan Axani.Sc.

The neuropeptide VGF produces antidepressant-like behavioral effects and enhances proliferation in the hippocampus
No full textBrain-derived neurotrophic factor (BDNF) is upregulated in the hippocampus by antidepressant treatments and BDNF produces antidepressant-like effects in behavioral models of depression. In our previous work, we identified genes induced by BDNF and defined their specific roles in hippocampal neuronal development and plasticity. To identify genes downstream of BDNF that may play roles in psychiatric disorders, we have examined a subset of BDNF-induced genes also regulated by serotonin (5-HT), which includes the neuropeptide VGF (non-acronymic). To explore the function of VGF in depression, we first investigated the expression of the neuropeptide in animal models of depression. VGF was downregulated in the hippocampus following both the learned helplessness (LH) and forced swim test (FST) paradigms. Conversely, VGF infusion in the hippocampus of mice subjected to FST reduced the time spent immobile for up to 6 days, thus demonstrating a novel role for VGF as an antidepressant-like agent. Recent evidence indicates that chronic treatment of rodents with antidepressants increases neurogenesis in the adult dentate gyrus and that neurogenesis is required for the behavioral effects of antidepressants. Our studies using 3H-thymidine and bromodeoxyuridine (BrdU) as markers of DNA synthesis indicate that chronic VGF treatment enhances proliferation of hippocampal progenitor cells both in vitro and in vivo with survival up to 21d. By double immunocytochemical analysis of hippocampal neurons, we demonstrate that VGF increases the number of dividing cells that express neuronal markers in vitro. Thus VGF may act downstream of BDNF and exert its effects as an antidepressant-like agent by enhancing neurogenesis in the hippocampus.Peer reviewe
Including the public in pandemic planning: a deliberative approach
No full textBackground: Against a background of pandemic threat posed by SARS and avian H5N1 influenza, this study used deliberative forums to elucidate informed community perspectives on aspects of pandemic planning. Methods: Two deliberative forums were carried out with members of the South Australian community. The forums were supported by a qualitative study with adults and youths, systematic reviews of the literature and the involvement of an extended group of academic experts and policy makers. The forum discussions were recorded with simultaneous transcription and analysed thematically. Results: Participants allocated scarce resources of antiviral drugs and pandemic vaccine based on a desire to preserve society function in a time of crisis. Participants were divided on the acceptability of social distancing and quarantine measures. However, should such measures be adopted, they thought that reasonable financial, household and psychological support was essential. In addition, provided such support was present, the participants, in general, were willing to impose strict sanctions on those who violated quarantine and social distancing measures. Conclusions: The recommendations from the forums suggest that the implementation of pandemic plans in a severe pandemic will be challenging, but not impossible. Implementation may be more successful if the public is engaged in pandemic planning before a pandemic, effective communication of key points is practiced before and during a pandemic and if judicious use is made of supportive measures to assist those in quarantine or affected by social isolation measures.Annette J Braunack-Mayer, Jackie M Street, Wendy A Rogers, Rodney Givney, John R Moss, Janet E Hiller, Flu Views tea
