Crossing the school house gates : a media access audit of public high schools

The entire thesis text is included in the research.pdf file; the official abstract appears in the short.pdf file; a non-technical public abstract appears in the public.pdf file.Title from PDF of title page (University of Missouri--Columbia, viewed on October 14, 2009).Thesis advisor: Dr. Charles Davis.M.A. University of Missouri--Columbia 2009.This research tested the media access policy adopted by a large independent public school district in Oklahoma to determine if its high schools comport with district rules as applicable to self-governance theory. The researcher visited nine high schools in a large Oklahoma public school district and observed administrators' willingness to comply with their own Board of Education policy on media access. The researcher examined the levels of access granted reporters, if story the topic was a deciding factor in granting access, and the timeliness in which the administration responded. Seven of nine schools followed the policy, though not always in a timely manner. One school denied a request for access based on the story topic, while another sent the reporter off campus based upon her profession. Other administrators were unperturbed by a media presence in their schools, allowing the researcher to freely roam the school. During debriefing, many administrators reported that relationships between journalists and schools had more bearing on campus admission than strict interpretation of board policy.Includes bibliographical references

Approaches to learning of Irish students studying accounting

Several reports on accounting education have identified the development of students' learning to learn as the primary objective of accounting education. Higher education research identifies the approach to learning as a significant factor in the overall student learning experience. If accounting educators are to find ways to improve the educational experience of their students, they must understand how students learn and the effects of the learning context on learning approaches. This study examines the approaches to learning adopted by first year students enrolled on the B.A. in Accounting and Finance and the BBS at Dublin City University and assesses the impact of a number of contextual variables on these learning approaches

Motivations, expectations and preparedness for university: a study of accounting students in Ireland, the UK, Spain and Greece.

While evaluating the appropriateness of accounting education within universities has occupied researchers for many years, the harmonisation of the tertiary education process across Europe, through the Bologna Declaration, generates the need for comparative studies. This paper measures the motives, expectations and preparedness of students commencing the study of accounting at universities in four European countries. The findings reveal that while all students are motivated to progress to higher education for career-oriented reasons and to seek intellectual growth, considerable variation is evident between the students in the four settings with regard to motives, confidence, perceptions of preparedness for university and expectations concerning study effort. All of these factors may impact on students’ achievement of the common learning outcomes espoused by the Bologna process. There is a need for further research to enrich our understanding of educational processes across Europe and to consider the impact of harmonisation activities on students’ learning

Assessment of Magnetic Resonance Imaging Artefacts Caused By Equine Anaesthesia Equipment:A Cadaver Study

Acquisition of magnetic resonance images of the equine limb is still sometimes conducted under general anaesthesia. Despite low-field systems allow the use of standard anaesthetic equipment, possible interferences of the extensive electronic componentry of advanced anaesthetic machines on image quality is unknown. This prospective, blinded, cadaver study investigated the effects of 7 standardised conditions [Tafonius positioned as in clinical cases, Tafonius on the boundaries of the controlled area, anaesthetic monitoring only, Mallard anaesthetic machine, Bird ventilator, complete electronic silence in the room (negative control), source of electronic interference (positive control)] on image quality through the acquisition of 78 sequences using a 0.31T equine MRI scanner. Images were graded with a 4-point scoring system, where 1 denoted absence of artefacts and 4 major artefacts requiring repetition in a clinical setting. A lack of STIR fat suppression was commonly reported (16/26). Ordinal logistic regression showed no statistically significant differences in image quality between the negative control and either the non-Tafonius or the Tafonius groups (p = 0.535 and p = 0.881, respectively), and with the use of Tafonius compared to the other anaesthetic machines (p = 0.578). The only statistically significant differences in scores were observed between the positive control and the non-Tafonius (p = 0.006) and the Tafonius groups (p = 0.017). Our findings suggest that anaesthetic machines and monitoring do not appear to affect MRI scan quality and support the use of Tafonius during acquisition of images with a 0.31T MRI system in a clinical context

Catecholamine stress alters neutrophil trafficking and impairs wound healing by β2-adrenergic receptor-mediated upregulation of IL-6.

Stress-induced hormones can alter the inflammatory response to tissue injury; however, the precise mechanism by which epinephrine influences inflammatory response and wound healing is not well defined. Here we demonstrate that epinephrine alters the neutrophil (polymorphonuclear leukocyte (PMN))-dependent inflammatory response to a cutaneous wound. Using noninvasive real-time imaging of genetically tagged PMNs in a murine skin wound, chronic, epinephrine-mediated stress was modeled by sustained delivery of epinephrine. Prolonged systemic exposure of epinephrine resulted in persistent PMN trafficking to the wound site via an IL-6-mediated mechanism, and this in turn impaired wound repair. Further, we demonstrate that β2-adrenergic receptor-dependent activation of proinflammatory macrophages is critical for epinephrine-mediated IL-6 production. This study expands our current understanding of stress hormone-mediated impairment of wound healing and provides an important mechanistic link to explain how epinephrine stress exacerbates inflammation via increased number and lifetime of PMNs

Electric Field Standing Wave Effects in FT-IR Transflection Spectra of biological tissue sections: simulated models of experimental variability

The so-called electric field standing wave effect (EFSW) has recently been demonstrated to significantly distort FT-IR spectra acquired in a transflection mode, both experimentally and in simulated models, bringing into question the appropriateness of the technique for sample characterization, particularly in the field of spectroscopy of biological materials. The predicted effects are most notable in the regime where the sample thickness is comparable to the source wavelength. In this work, the model is extended to sample thicknesses more representative of biological tissue sections and to include typical experimental factors which are demonstrated to reduce the predicted effects. These include integration over the range of incidence angles, varying degrees of coherence of the source and inhomogeneities in sample thickness. The latter was found to have the strongest effect on the spectral distortions and, with inhomogeneities as low as 10% of the sample thickness, the predicted distortions due to the standing wave effect are almost completely averaged out. As the majority of samples for biospectroscopy are prepared by cutting a cross section of tissue resulting in a high degree of thickness variation, this finding suggests that the standing wave effect should be a minor distortion in FT-IR spectroscopy of tissues. The study has important implications not only in optimization of protocols for future studies, but notably for the validity of the extensive studies which have been performed to date on tissue samples in the transflection geometry
