A best protocol for acid sulphate soil detection, Ashfield
No full textAn early analysis of data for Acid Sulphate Soil ASS detection uses field based measurements of pH and laboratory based measurements of Cl/SO4 and SPOCAS at Ashfield, Western Australia. Statistically, no test is outstanding and the tests are not necessarily the same. Field pH testing is inexpensive and worth doing but statisti¬cally Field pH and Cl/SO4 are insignificantly related (P = 0.045) Fisherʼs Exact Test. Cl/SO4 testing rarely gives a negative result. When the Field pH gives a negative result, Cl/SO4 is unlikely to confirm it. Field pH and SPOCAS are significantly re¬lated (P = 0.022, Fisherʼs Exact Test); large numbers of positive and negative results lend power to this statement. It is particularly concerning that when the Field pH and Cl/SO4 agree, the SPOCAS only gives a positive result 68% of the time, a figure not statistically different to 50%. The follow-up suggests numerical readjustments of the cutoff for the tests and the protocol for ASS in Western Australia, in the shape of a decision tree
Coping strategies for social well-being and social development intervention: young women and unintended pregnancy in Mozambique
No full textUsing the concept of coping strategies, this thesis is essentially concerned with the wayyoung women in Mozambique achieve social well-being during the life event of unintendedpregnancy. Unintended pregnancy in Mozambique places significant strain on informal andformal relationships, educational access, economic stability and the maintenance of goodhealth. It also has significant implications for young women’s roles, responsibilities and statuswithin families and communities (CEDAW 2005). Twenty one qualitative semi-structuredindividual interviews were completed with young women (16-19 years old) who have recentlyhad an unintended pregnancy, as well as eight focus groups using a vignette with youngwomen (16–21 years old) from youth associations and fourteen individual interviews with keyinformants (those working in the area of sexual and reproductive health with youth andadolescents). From these three forms of rich data, the relationships young women have withothers, the negotiations they engage in and the coping strategies they employ are illuminated.This research contributes to an increased understanding of unintended pregnancy and theways young women respond and ‘cope’ with this life event (as a process) largely via differentforms of social interaction. The chosen methodology was designed to elicit this type ofknowledge drawing on different disciplinary interpretations of coping strategies. Althoughunintended or early pregnancy in young women has developed as a key social developmentconcern in recent years (Hainsworth 2002; Mahy 2002; Westoff 2003; UNFPA 2007), thisresearch indicates that policy strategists in Mozambique struggle to develop adequate andeffective intervention in response. The narratives shared by young women, and the analysisdeveloped through chapters four to seven builds a complex picture for intervention, as familyrelationships remain a major factor for social and economic well-being. The socially andculturally constructed nature and predominant location within families mean that macrostrategies and community level intervention has limited impact during unintended pregnancy.Strengthening relational strategies (both formal and informal) through social developmentintervention is therefore necessary for young women to access social and organisationalresources for coping and social well-being. By using the concept of coping strategies, thejuxtaposition of ‘copers’ and ‘non-copers’, the relationship between agency and structure, thestrategies employed at different levels, the significance of social interaction and coping as aprocess has been opened up to scrutiny. This thesis not only evaluates and critiques modelsof social development, but also argues that the concept of coping strategies can be usefullyapplied to inform social development in ways that address both individual and collective wellbeing
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Author, publisher and bookseller : a tripartite synergy in Nigerian book industry
No full textThis work is about the roles of Author, Publisher and Bookseller in Book development in
Nigeria. The paper started by delving into the history of Book Publishing in Nigeria after
which it proceeded by defining who an author, a publisher, and a bookseller is and
expatiated on the indispensable roles of these key actors in Nigerian Book Industry and in
the emerging Information Society. Furthermore, the various constraints to book
development were identified while the paper advised on how the Book Industry can be
further promoted in Nigeria. However, the paper concluded and made recommendations
on how the Book sector can help in enhancing scholarship in the country

Abstract
PURPOSE: To evaluate the role of topical mitomycin C in corneal wound healing (CWH) after photorefractive keratectomy (PRK) in highly myopic eyes.
DESIGN: Prospective, double-masked, randomized clinical trial.
PARTICIPANTS: Seventy-two eyes of 36 patients affected by high (>7 diopters) myopia.
METHODS: In each patient, one eye was randomly assigned to PRK with intraoperative topical 0.02% mitomycin C application, and the fellow eye was treated with a placebo. Postoperatively, mitomycin C-treated eyes received artificial tears (3 times daily, tapered in 3 months), whereas the fellow eye was treated with fluorometholone sodium 2% and artificial tears (3 times daily, tapered in 3 months).
MAIN OUTCOME MEASURES: Uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA), contrast sensitivity, manifest refraction, and biomicroscopy. Contrast sensitivity was determined using the Pelli-Robson chart. Corneal confocal microscopy documented CWH.
RESULTS: Mean follow-up was 18 months (range, 12-36). No side effects or toxic effects were documented. At 12-month follow-up examination, UCVAs (logarithm of the minimum angle of resolution) were 0.4+/-0.48 and 0.5+/-0.53 (P = .03) in mitomycin C-treated eyes and corticosteroid-treated eyes, respectively. At 1 year, corneal haze developed in 20% of corticosteroid-treated eyes, versus 0% of mitomycin C-treated eyes. At 12, 24, and 36 months, corneal confocal microscopy showed activated keratocytes and extracellular matrix significantly more evident in untreated eyes (Ps = 0.004, 0.024, and 0.046, respectively).
CONCLUSION: Topical intraoperative application of 0.02% mitomycin C can reduce haze formation in highly myopic eyes undergoing PRK.

Author Co-Citation Analysis (ACA): a powerful tool for representing implicit knowledge of scholar knowledge workers
No full textIn the last decade, knowledge has emerged as one of the most important and valuable organizational assets. Gradually this importance caused to emergence of new discipline entitled ―knowledge management‖. However one of the major challenges of knowledge management is conversion implicit or tacit knowledge to explicit knowledge. Thus Making knowledge visible so that it can be better accessed, discussed, valued or generally managed is a long-standing objective in knowledge management. Accordingly in this paper author co- citation analysis (ACA) will be proposed as an efficient technique of knowledge visualization in academia (Scholar knowledge workers)
