Knowledge management and organisational performance: a literature review
No full textAlthough knowledge management is considered as a very recent phenomenon,
research in to knowledge and the management of the knowledge within the business context
has grown dramatically over the last few years, in a number of different directions. As a result,
a great deal about, what knowledge is and the ways in which knowledge is managed, have been
addressed by many authors. However, despite the growing body of theory, there are relatively
few knowledge management texts that make an explicit connection between knowledge and
performance. Knowledge is not always utilised and that utilised knowledge does not always
result in improved performance. Thereby measurement of performance is of utmost importance
for an organisation to ensure the successful implementation of knowledge management
exercise. This paper is aimed at reviewing literature on both knowledge management and
organisational performance. Based on the review it was underlined knowledge management as
a strategy which leads to performances. The paper highlighted the extreme importance of
looking into the performance measures which can be deployed in knowledge organisations and
recommends further research to be carried out on this regard

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

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.

Managing construction workers and their tacit knowledge in a knowledge environment: A conceptual framework
No full textWithin the construction industry, it is increasingly being acknowledged that
knowledge management can bring about the much needed innovation and improved
performance the industry requires. Nevertheless, sufficient attention is still to be received for
the concept of the knowledge worker and their tacit knowledge within construction industry.
Yet, proper understanding and management of this resource is of immense importance for the
achievement of better organisational performance. Hence, this paper aims to devise a
theoretical framework for managing construction knowledge worker and their tacit knowledge
based on review and synthesis of literature. Paper stresses the importance of construction
knowledge worker and tacit knowledge through review of literature and highlights prevailing
gap due to lack of attention and recognition given to the tacit knowledge in the construction
industry. Based on identified gap research aim, objectives and hypotheses are devised. As the
specific research methodology, the social constructionism stance in terms of epistemological
undertakings and idealistic approach under the ontological assumptions with value laden
purposes are suggested. Further, it recommends the deployment of multiple exploratory case
studies approach with triangulation techniques
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

No full textRisk Assessment on Community-Based Post-Disaster Housing Reconstruction Project
No full textRisk management method has been acknowledged to be an important factor to
achieve the project objectives in the construction industry. However, its
implementation on community-based post-disaster housing reconstruction is hardly
found. Accordingly, the objective of this paper is to assess high risk events that
affect time completion of community-based post-disaster housing reconstruction
project (CPHRP). Three most recent and most severe areas affected by earthquake
and tsunami in Indonesia were chosen as case study locations: Aceh (2004),
Yogyakarta (2006) and West Sumatra (2009). Questionnaire survey was selected as
data collection method and emailed to respondents to assess the probability of
occurrence of particular event and its impact on time completion. The response rate
was considered as very satisfactory (79%) with sixty five questionnaires were
categorized as valid. Result shows that twenty events can be categorised as high risk
and are mostly originated from government
