Texto completo da fonteResumo:
This survey of the achievements of the Research Libraries Group (RLG) and its Art and Architecture Group shows the effectiveness of a collaborative approach in developing best practices and standards, and implementing new methodologies and technologies, to benefit the international art library and research communities. RLG members in Europe, North America and Australia include many of the major art research libraries. RLG offers services such as the RLIN bibliographic database and the MARCADIA retrospective conversion service in conjunction with projects documenting sales catalogue records (SCIPIO), preserving serials (the Art Serials Preservation Project) and facilitating the interloan of material between members. More recently the partnership between the RLG and the Getty Information Institute has made available an enormous range of art documentation work carried out by the Getty: standards and authority control work such as the Art & Architecture Thesaurus, the Union List of Artists’ Names and the Thesaurus of Geographic Names. In the 1980s the RLG conducted a survey identifying information needs in the humanities, which has led to resources such as the Bibliography of the History of Art becoming widely accessible, with the Provenance Index to follow shortly. This partnership is now active in the museum field, attempting to bridge the gap between the domains of secondary and primary materials in the field of art research. The REACH project (Record Export for Art and Cultural Heritage) is experimenting with the export of existing machine-readable data from heterogeneous museum collection systems, and testing the feasibility of designing a common interface for access which will complement RLG’s other resources.

The wide spectrum of full text and bibliographic information resources (e. g. Web of Science, Scopus), which Library for Natural Sciences of the Russian Academy of Sciences (LNS RAS) had in its subscription for the last few years, was a ground for the autors' efforts in developing of the modern system of selective dissemination of information (SDI system). At the same time, acquisition of information sources on traditional media has been steadily decreasing in recent years.Sources of bibliographic information in this SDI system are bibliographic databases Web of Science and Scopus, and full-text platforms of foreign scientific publishers (currently — several dozen, including John Wiley & Sons, Springer Nature and ScienceDirect).The users of the SDI system have opportunity to get two kinds of service: the first one is informing on the current issues of the scientific journals which are preselected by user himself; the second one is the thematic informing based on the keywords of user thematic requests. This SDI system has the important feature that distinguishes it from traditional definition of SDI systems: we do not restrict either lists of journals reported by users nor the bibliographic sources in thematic sets by the list of full text sources available via library’s subscription. The only condition for including specific journal in the SDI system for the first kind of service or including the bibliographic source in thematic sets for the second kind of service is existing of the source as electronic web entity. If user has made order for full text material from contents/thematic information set, the library retrieves such full text material via all available ways beginning with library’s subscription and finishing with interlibrary loan.We have selected e-mail sending of personalized information sets for our users, as it was the mode selected as preferable mode by our users themselves. Personalized information sets include ordinary fields of bibliographic record (incl. abstracts if available in protosource) and some fields for increasing navigation options of records: link to full text via DOI, link for article record in Scopus and PubMed, information about library’s subscription for source where specific record is published.

In 2009, a new company, SkyRiver, began offering bibliographic utility services to libraries in direct competition to OCLC’s WorldCat. This study examines the differences between the two databases in terms of hit rates, total number of records found for each title in the sample, number of non-English language records, and the presence and completeness of several elements in the most-held bibliographic record for each title. While this study discovered that the two databases had virtually the same hit rates and record fullness for the sample used—with encoding levels as the sole exception—the study results do indicate meaningful differences in the number of duplicate records and non-English-language records available in each database for recently published scholarly monographs.

Texto completo da fonteResumo:
The work of Latin American women artists is not adequately documented, nor is it sufficiently recognised in the major art reference works and bibliographies which thus fail to facilitate access even to documentation which is available in the USA. The author has been working towards a bibliographic apparatus that will bring together readily available sources on 20th century Latin American women artists. Much material has been found in the Art Exhibition Catalog collection in the Arts Library at the University of California at Santa Barbara. Two Cuban artists, Ana Mendieta and María Martínez-Cañas, are just two of some 200 artists from 20 countries represented in this project.

Proceedings of the AAAI Conference on Artificial Intelligence 33 (17 de julho de 2019): 9601–6. http://dx.doi.org/10.1609/aaai.v33i01.33019601.
Texto completo da fonteResumo:
Automatically extracted metadata from scholarly documents in PDF formats is usually noisy and heterogeneous, often containing incomplete fields and erroneous values. One common way of cleaning metadata is to use a bibliographic reference dataset. The challenge is to match records between corpora with high precision. The existing solution which is based on information retrieval and string similarity on titles works well only if the titles are cleaned. We introduce a system designed to match scholarly document entities with noisy metadata against a reference dataset. The blocking function uses the classic BM25 algorithm to find the matching candidates from the reference data that has been indexed by ElasticSearch. The core components use supervised methods which combine features extracted from all available metadata fields. The system also leverages available citation information to match entities. The combination of metadata and citation achieves high accuracy that significantly outperforms the baseline method on the same test dataset. We apply this system to match the database of CiteSeerX against Web of Science, PubMed, and DBLP. This method will be deployed in the CiteSeerX system to clean metadata and link records to other scholarly big datasets.

Texto completo da fonteResumo:
The study reveals the publications of the Ukrainian Free Academy of Sciences in Germany that are available in the fund of Foreign Ukrainistics Department of Vernadsky National Library of Ukraine and represent the process of its formation, activity, development, and the names of scientists whose efforts led to UFAS. Sources of funding the scientific institution and publishing opportunities was found out, and the book description of the documents along with their meaningful content was carried out. A significant number of documents published by UFAS reveal its scientific directions and opportunities. Through the efforts of UFAS in Germany, the scientific world has been replenished with dozens of important works which represent Ukrainian science. The review of UFAS publications was published in a separate series “UFAS Chronicle”, and the publication “UFAS Bulletin” published monthly reports on the activities of the institution. Some groups (sections) prepared their “Collections” for printing. Monographs on current research were being published. The first issue of the bibliographic journal “Ukrainian Bibliological News”, the main topics of which are bibliology, archival science and library science, was published in the series “Bibliography”. The magazine kept records of Ukrainian printed materials in exile, published articles-reviews of UFAS leading scientists, analyzed the history of the magazine and reviews of new books about the figures of the Ukrainian word. Separate editions were published in the same series. An important task of the activities of FUD is to open the fund and popularize the diaspora book culture. The foundations for the further development and activities of UFAS in Canada and the United States were laid precisely in Augsburg, Germany. By organizing a center for the preservation and development of Ukrainian science in Germany, Ukrainian scientists have launched activities to establish strong scientific ties with European scientists and made it possible to integrate Ukrainian science into the world.

Texto completo da fonteResumo:
In addition to a list of valid names and synonyms, as provided by the Trichoptera World Checklist, access to the primary literature itself is essential for research in Trichoptera taxonomy and systematics. To improve access to bibliographic information, we established the Trichoptera Literature Database, http://www.trichopteralit.umn.edu, a bibliographic database of over 8,500 citations of literature on Trichoptera. In addition to compiling bibliographical information, we provided access to over 450 high quality Portable Document Format files (PDFs) of historically important, rare, or out-of-print older works as well as more current literature. To provide universal web access to this bibliographical resource, we constructed a dynamic, custom-designed, web application (PHP, Symfony framework) created to import Extensible Markup Language (XML) from the EndNote data file. The database allows the user to search by author and year of publication, displays citations in a standard bibliographic format, and provides download links to available PDF literature. Existing bibliographies of Trichoptera literature and online access to Zoological Record databases were used to accumulate citations. Protocols for scanning literature, issues regarding copyright, and procedures for uploading citations and PDFs to the database are established. We hope to create a collaborative framework of contributors by seeking regional, subject, or language organizers from the community of Trichoptera workers to assist in completing and maintaining this resource with the goal of lowering barriers to efficient access to taxonomic information.

Texto completo da fonteResumo:
Traditionally, archival description remained distinct from bibliographic description due to differences in material format, usage, and professional traditions. However, archival descriptive standards and practice have undergone numerous changes in recent years. This evolution is in part due to the advent of MARC and its adoption by the academic archives community. How much influence has the use of MARC and overall bibliographic description had on academic archival description as well as on the collaboration between traditional catalogers and archivists? To address this question, this article presents the findings of a landscape survey of the Association of Research Libraries members' descriptive practices surrounding MARC records, linked and embedded metadata, and authority records. Survey responses indicate that archival descriptive work remains concentrated in the archival domain, with archivists creating description as one component of job responsibilities at most institutions. Descriptive work—including MARC record creation—has not been passed off to cataloging colleagues despite their longer professional experience with the standard even though the OPAC is the most commonly cited archival information system available to respondents. Decisions about appropriate levels of description, standards to be employed, workflows, and other factors related to archival description do not appear to rely on external buy-in or approval in most repositories, and descriptive practices employ a mix of standards from both the archival and bibliographic traditions. These and other findings provide a baseline understanding of current archival descriptive practices and workflows, enhancing our ability to improve archival description and therefore findability and access to archival materials.

Teper, J. H. (2019). Considering “sameness” of monographic holdings in shared print retention decisions. Library Resources & Technical Services, 63(1), 29-45. https://doi.org/10.5860/lrts.63n1.29
Abstract
Objective – To investigate the degree to which books catalogued using the same bibliographic record differ and to consider the implications of these differences for cooperative monographic print retention programs.
Design – Book condition survey.
Setting – Academic library consortium in the United States of America.
Subjects – 47 monographic titles, publication years 1851-1922, held by all consortium members and catalogued using the same respective OCLC record number. 625 out of a possible 705 circulating copies of these titles were available for item-level analysis via interlibrary loan.
Methods – Book condition surveys were completed for all items and the resulting sets of assessment data points were analyzed to reveal trends.
Main Results – 3.4% of items analyzed exhibited cataloguing errors (i.e., were catalogued using the wrong OCLC records), 56.8% retained their original bindings, 17.8% were marked to show previous ownership, 95.7% were complete with no missing content, 9.8% had no damage, and 18.9% had received identifiable preservation action.
Conclusion – Books catalogued using the same OCLC record demonstrated many differences when compared at the item level. These differences are important in light of shared print retention programs and highlight a need for inquiry into the number of copies that should be retained to minimize the loss of uniqueness in print materials.

Lyandvert, Max School of Theatre Film & Media UNSW. "Origins and destinations: representation in the theatre of Romeo Castellucci". Awarded by:University of New South Wales. School of Theatre, Film and Media, 2006. http://handle.unsw.edu.au/1959.4/28238.
Texto completo da fonteResumo:
This thesis: Origins and Destinations: Representation in the theatre of Romeo Castellucci, investigates the working methodology of the Italian theatre director, Romeo Castellucci and his company, Societas Raffaello Sanzio. It provides an account of Societas Raffaello Sanzio???s history, working methods, a detailed reading of the thematic and philosophical landscape in their works especially Genesi: from the museum of sleep, and the cycle: Tragedia Endogonidia, and a discussion on the company???s artistic process towards the formation of its compositions and performances. This research and investigation is based on numerous viewings of most of the company???s theatre works created in the last six years, interviews with Romeo Castellucci as well as other participating artists, two privileged periods of observation (residencies) in Italy of the rehearsal and creation processes of three shows, and the analysis and discussion of some of the key critical and intellectual responses to the work of Romeo Castellucci. The thematic focus of the thesis is the notion of Origins and Destinations, and its relationship with the language of representation in Romeo Castellucci???s theatre. The theoretical discussion in the thesis is organised around Giorgio Agamben???s notion of Potentiality within the composition and content of Castellucci???s theatre. This concept provides a link between the key ideas of Origins, Destinations and Representation. Castellucci???s application of Agamben???s Potentiality deconstructs dramatic structure, narrative and action down to the fundamentals of the act itself, separated from its meaningful context. It is the conclusion of this thesis, that in the instant of this singular act, Romeo Castellucci manages to represent a point where origin and destination meet, or a point where they both are, for an instant, one and the same thing.

Mahmood, Raasheed School of Sociology & Anthropology UNSW. "Being and doing ???Bengali-Muslims??? in Sydney: the construction of Halal and Haram". Awarded by:University of New South Wales. School of Sociology and Anthropology, 2006. http://handle.unsw.edu.au/1959.4/30525.
Texto completo da fonteResumo:
This is a study against essentialist generalisations. Empirically, the study has been conducted to understand the food related practices among the Bengali-Muslim migrants in Sydney based on the dichotomy of Halal (permitted in Islam) and Haram (prohibited in Islam). Instead of evaluating Islam and Muslim communities as monolithic and undifferentiated this study reveals the localised actualisation of Islam which serves as a conditioning factor for these Bengali-Muslim migrants. Adopting a naturalistic methodological approach a number of ethnographic tools have been used to reveal the complex multifaceted processes through which Sydney???s Bengali-Muslim migrants negotiate the situational convergence and divergence between their ethnic identity as Bengali and their religious identity as Muslim. As a significant site of this interplay this study discovers from their food related practices that the Bengali-Muslim migrants in Sydney construct the notion of Halal-Haram food rules and regulations through the dialectics of their Bengali-informed Islam. The Bengali version of Islam poses considerable challenge to the modernist opposition between secularism and religion which is quite inadequate to understand the way the Bengali-Muslims historically negotiate both of these in the form of overlapping consensus. The findings of the study exhibit that this situationally shifting emphasis on their secular Bengali identity at one point of time and on their religious Muslim identity at another determines their decisive practices regarding food consumption in a Western cultural milieu. The Bengali-Muslim migrant participants of this study tend to perceive the notion of Halal-Haram in multiple ways so as to fit the pragmatic realities of their migrant life, which eventually leads them to reconstruct, renegotiate or even discard the scriptural/theological/authoritative discourse. Such underlying properties of food practices vindicate the argument that any stereotypically standardised notion of ???Islam??? is inadequate to understand varied Muslim migrant communities across the globe. Rather specific Muslim migrant community should be studied along with a profound understanding of their very contextual nature and historical formations.

Texto completo da fonteResumo:
This thesis adopts post-colonial theory as a reading strategy to address both fiction and interdisciplinary critical writing on the subject of tourism. The introduction argues for the viability of this methodology, highlighting similarities between the ideological underpinnings of tourism and imperialism, especially in relation to the power of the gaze. The first chapter draws on analyses of early exploration and travel writing to advance the argument that as the ideology of empire was encoded in travel writing, so contemporary tourist culture, in so far as it has inherited this discourse, continues to operate within it. I suggest that in much the same way as the explorer???s gaze was a form of creating knowledge disseminated through writing, fiction constitutes a cultural production that contests the power of the gaze. The second chapter focuses on the ambivalent effects of the commodification of culture caused by the tourist industry. I argue that cultural tourism, centred on heritage and history, has constituted a platform from which to review conventional representations of Australian history in a way that demonstrates the relevance of heritage to contemporary national narratives. The third and final chapter examines the relationship between cultural performances in tourism and subject formation, contending that the repetitive nature of performance offers an ideal opportunity to interpolate transformative views of both locals and tourists into the conventional tourist discourse.

Texto completo da fonteResumo:
The quality of visual perception with epiretinal electric stimulation strongly depends on the configuration of electrode arrays. Such arrays at the surface of the retina should excite only cells within a local area, but in practice, they exhibit some cross-talk, possibly leading to a smearing of focal activation of the retina. In this study, a passive model of extracellular voltage distribution arising from epiretinal stimulation is solved using the method of finite differences, in order to explore the voltage and current distributions of a hexagonal electrode array configuration. Results of this study suggest that the hexagonal electrode arrangement is effective in providing targeted focal activation of retinal tissue. Cross-talk between hexagonal clusters may be minimized by stimulus paradigms which utilize six return (or guard) electrodes around each stimulus electrode.

Texto completo da fonteResumo:
In this thesis I examine the ways in which the modern state addresses sex. I want to ascertain by what considerations the state is informed in its relationship to sex. What is behind the state???s regulation of sexual practices? What is its interest in regard to sex? To answer these questions I examine fundamental artefacts of the modern state, especially the law (but also the bureaucracy), as directed by the 1993 English court case of Brown. Brown involves the search for the sexual subject; The Lords in Brown were at a loss for how to conceptualise the subject before them. Their search is my own: who is the sexual subject? What is his relationship to the state? To answer these questions, Brown directs me for authority to two widely separated moments of supposed classic ???discontinuity???: the 1957 Wolfenden Report, and the late-Victorian Queen???s Bench. These two moments in government - the 1960s and the 1880s - are usually depicted as ideologically different, indicating discontinuity, difference, change and perhaps even revolution between the relative approaches of the state to sex. And yet, in Brown, both are upheld as appropriate contemporary authorities on sex, the individual and the state. Here I take my cue from the Lords and interrogate the artefacts of these two periods in government to ascertain the story of the 20th century state???s relationship to sex. My thesis is a political analysis that incorporates genealogy in its focus on law as indicative of the state. It incorporates a detailed study of primary artefacts of the state: detailed analyses of seemingly discontinuous moments including individual court cases, individual Committees, individual treatises and opinions and political memoirs. I conclude by drawing together my overall argument, that during the 20th century there has been no radical change of the modern state in regard to sex, and that the success of the permissive mythology has generally blinded us to this fact. Not only have we mistaken the nature of the permissive state as concerned with evolution, we have erroneously been persuaded of the blanket repression of the Victorian state. The big break, the discontinuity of the 1960s, that often is described as ???revolutionary??? (and inevitable in the teleology of progress), is a re-configuration of the same object as the Victorian state. The permissive state enacts the latest stage in the great Victorian project of embodying the sexual subject ??? a subject at once embodied and created as an object of control.

Niechoda, Beata School of Surgery UNSW. "In vivo bone formation using Adipose Derived Stromal Stem Cells. The histomorphometry of the ovine defect model". Awarded by:University of New South Wales. School of Surgery, 2006. http://handle.unsw.edu.au/1959.4/27217.
Texto completo da fonteResumo:
The use of stem cells to augment the healing of bone defects represents an exciting new frontier in many surgical disciplines. This thesis verified the in vitro osteogenic capability of ovine Adipose Derived Stromal Stem Cells (ADSCs) and Bone Marrow Derived Stem Cells (BMSCs), examined the in vivo osteogenic potential of the ovine ADSCs population and compared it to the in vivo osteogenic potential of ovine BMSCs. The pilot study used both cell populations, expanded and osteogenically stimulated ex vivo and mixed with resorbable porous hydroxyapatite-calcium carbonate bone graft substitute (ProOsteon 200R, Interpore Cross International, Irvine, CA). This study demonstrated the preferred length of time in ex vivo osteogenic stimulation of the ADSCs and BMSCs populations to promote the bone formation in vivo to be 7 days. In the main ovine study which employed 48 wethers, ADSCs and BMSCs were expanded, stimulated osteogenically for 7 days, mixed with ProOsteon 200R and deposited in an autologous manner into a bilateral medial femoral condyle confined cancellous defect. In vivo performance of 7 treatment groups was examined: 1. ???Bone autograft/ADSCs???, 2. ???Bone autograft/BMSCs???, 3. ???ProOsteon 200R/ADSCs???, 4. ???ProOsteon 200R/BMSCs???, 5. ???Bone autograft???, 6. ???ProOsteon 200R??? and 7. ???Empty defect???. The time-points were: 2, 4, 8 and 12 weeks. The analysis of the harvested specimens used the following methods: computerized tomography, histological assessment, histomorphometry and immunohistochemistry. There was a progressive and time dependant increase in woven bone in the defects treated with ADSCs and BMSCs across all time points. The amount of woven bone in the defects treated with the combination of ADSCs and ProOsteon 200R was comparable with the defects treated with the combination of BMSCs and ProOsteon 200R. In addition, the combination of ADSCs or BMSCs and ProOsteon 200R demonstrated no more bone than ProOsteon 200R alone. However, the ???Autograft/BMSCs??? and ???Autograft/ADSCs??? groups demonstrated a remarkable increase in the amount of woven bone formed in the defects across all time points when compared with all other groups. In addition, the amounts of bone formed in the ???Autograft/BMSCs??? and the ???Autograft/ADSCs??? group were comparable across all timepoints. The results of these studies support the hypothesis that ovine ADSCs and BMSCs populations in combination with the bone autograft can increase the formation of woven bone in the autologous orthotopic environment in a comparable manner.

Wang, Xiu Ying Optometry & Vision Science Faculty of Science UNSW. "Distribution of ocular parameters measured by optical coherence tomography in a childhood population". Awarded by:University of New South Wales. School of Optometry and Vision Science, 2006. http://handle.unsw.edu.au/1959.4/28333.
Texto completo da fonteResumo:
Purpose: To document the distribution of macular, retinal nerve fibre layer (RNFL) thickness and optic disc parameters, as measured using optical coherence tomography (OCT) in a population-based sample of young persons and to examine the relationship of these measurements to ocular variables (spherical equivalent refraction [SER] and axial length) and systemic variables (age, gender, anthropometry, ethnicity and birth parameters). Methods: A stratified random cluster sample of 6- and 12-year-old school students from across the Sydney metropolitan region were surveyed and examined using non-contact methods (including biometric measurements with the IOL Master and Canon RK-F1) to determine axial length and SER. The 3rd generation Optical Coherence Tomography instrument (Zeiss Stratus OCT, Dublin, CA, USA) was used to measure macular and RNFL thickness and major optic disc parameters in this sample. Ethnicity and birth parameters were derived using questionnaires. Anthropometric parameters, such as height and weight, were measured using standard methods. Results: The thickness of the foveal, central, inner macular, outer macular and macular volume parameters was normally distributed in both age cohorts. The temporal quadrant was thinner than all other quadrants at both the inner and outer macular regions. The central and inner macula was significantly thicker in boys than in girls, and in Caucasian than in East Asian children. The inner and outer macular regions were slightly, but significantly, thinner with increasing axial length, or myopic refraction. On the other hand, these corresponding regions were significantly thicker with more hyperopic SER. RNFL thickness and RNFLestimated integral were normally distributed in both age groups. RNFL thickness was thinnest for the temporal quadrant, followed by the nasal, inferior, and superior quadrants. RNFL average thickness was marginally greater in boys than in girls and in East Asian than in Caucasian children. The RNFL was thinner with both greater axial length and less hyperopic refractions. Optic disc, optic cup and neural rim parameters were also normally distributed in this young population. In analyses that adjusted for potential confounders, optic disc area increased significantly with axial length and refraction. Neural rim area increased with axial length. There were minimal gender differences in the two age groups. Most optic disc and optic cup dimensions were significantly larger in East Asian than in Caucasian and Middle Eastern children. The foveal minimum and overall RNFL thickness were similar in both age cohorts, while other retinal regions and optic disc size were slightly larger in the 12- than the 6-year-old children. Amblyopic eyes had greater foveal minimum thickness than the normal fellow eye of individual children and the right eyes of non-amblyopic children. Birth weight and head circumference were positively correlated with both RNFL and macular thickness. Conclusions: Macular thickness, RNFL thickness and optic disc parameters were normally distributed in these two age groups of children. Axial length and refraction were important ocular biometric determinants of macular thickness and RNFL thickness. Significant ethnic differences were also demonstrated. RNFL average thickness was also positively associated with optic disc area. Central macular thickness increased in amblyopia. These findings have implications for the interpretation of OCT measurements in research and clinical practice in both children and adult.

Stapledon, Nigel David Economics Australian School of Business UNSW. "Long term housing prices in Australia and some economic perspectives". Awarded by:University of New South Wales. School of Economics, 2007. http://handle.unsw.edu.au/1959.4/29488.
Texto completo da fonteResumo:
This thesis constructs, principally from primary sources, a long term time series for house and land prices for Sydney and Melbourne, and house price and rental yield series for Australia. These new series span the period 1880-1965 and give an historical perspective beyond the period from 1970 for which existing house price time series begin for Australia and for most of the world. The price series indicates that the modern experience (i.e. since the 1970s) of a significant upward trend in real prices differs markedly from the experience in the first half of the 20th century when house prices moved very little. The thesis then takes several approaches to explaining the apparent shift in direction in the mid 20th century. The first approach examines house prices in terms of demand and supply variables. Urban theory says that demographic and income factors are critical. However, assessed over this long time span, these demand factors do not offer a satisfactory explanation. Additionally, it is found that there is no cointegrating relationship between prices and income. Rather, it appears that supply factors have probably been the pivotal influence in explaining the shift in direction, consistent with a growing literature which focuses on the role of regulation and other constraints on supply. In Australia???s case, government policies imposing capital contributions on the cost of land appear to be a major factor. The second approach taken is to view housing in terms of asset pricing as more typically applied to the equity market by Campbell and Shiller (1988) and others. A central debate is whether or not there has been a structural fall in the equity yield and given the parallel fall in the house yield, this question is posed for housing. The thesis finds that tax and other factors can explain a structural decline in the housing yield. The house rental yield appears to be a better predictor of future rental growth and a negative predictor of future returns.

This study investigates the relationship between learning approaches and the development of clinical reasoning ability. The main questions for the study were: Is there a statistically significant relationship between students??? learning approaches and development of clinical reasoning ability? If there is a relationship between approaches to learning and development of clinical reasoning ability, which students develop this ability faster? And How does learning approach change relate to the development of reasoning ability? The Revised Two-Factor Study Process Questionnaire (R-SPQ-2F) was used in order to evaluate participants??? learning approaches and Diagnostic Thinking Inventory (DTI) to measure participants??? diagnostic thinking ability. In order to determine changes of learning approaches, the same students were invited to fill out the same questionnaires one year later. This quantitative study was followed by a qualitative inquiry including in-depth interviews aimed at exploring the association of a change in learning approach score with the development of clinical reasoning ability. These interviews also explored the factors influencing learning approaches of these students. Those students with the greatest change in R-SPQ-2F scores between the two surveys were selected for interview. Analysis of the findings of both the quantitative and qualitative phases of this research leads the researcher to conclude that; - there is a correlation between ongoing learning approaches and the development of clinical reasoning ability; this correlation is positive if the approach is deep and it is negative if the approach is surface, - progress towards either end of the learning approach continuum is associated with observation of experts, reasoning practice and/or feedback from experts, and - progress towards either end of the learning approach continuum seems an earlier and better indicator of developing reasoning ability than categorization of learning approach because both learning approach change and the factor causing this change were associated with the development of clinical reasoning ability. This study contributes to understanding of the importance of ongoing learning approaches and the development of clinical reasoning ability by encouraging deep learning approach characteristics. Factors affecting learning approaches are also associated with the development of clinical reasoning ability. Their effect is more than expected.

Texto completo da fonteResumo:
Flatness, levelness and plastic shrinkage cracks are three important parameters in the evaluation of the performance of concrete floor surfaces. The rapidly developing concrete floor industry overseas has resulted in a great deal of improvement in the methods for evaluation of surface flatness and levelness. This research encompasses a review of the development and evolution of codes in other countries, an evaluation of the current status in Australia, and reliable evaluation methods for concrete floors. The end result aims to present a comparison of the varying degrees of reliability of the different methods of measurement theoretically and demonstrates the feasibility of specified tolerance through the analysis of field data from actual projects. It also analyses the general assumption that concrete slabs exposed to hot weather conditions soon after casting is prone to plastic shrinkage cracking and its implications. Identifying factors influencing flatness, levelness and plastic shrinkage cracking of concrete slab surface and investigation of their effects are included in this research. Through statistical analysis, significant factors, such as the construction method, environmental conditions and the method of measurement are identified. In addition, sunlight intensity and capacity of concrete bleeding were factors investigated with regard to concrete surface evaporation rate. The monitoring of plastic shrinkage crack initiation and development is an important task in the research of concrete slabs. The research on plastic shrinkage cracking of the slab surface resulted in the development of a digital image analysis method. This method focuses on mapping cracks (MC) and measuring crack width (MCW). Other information such as crack growth over time can also be obtained based on MC and MCW. An accurate method for the measurement of crack width has been developed based on sliced crack image data. Therefore, this method can determine the location of the maximum crack width and measure it with a desired precision.
