Best-value in Korean public building construction
No full textAlthough the low-bid system has played a major role in public building construction sector for a long time, this system has arguably delivered work of low quality, an continued and rising number of claims within the industry. With these challenges in mind, the Korean government has sought to examine and possibly adopt best-value procurement as an alternative approach to delivering public building construction projects within Korea. The reality however is that although delivering arguably a number of advantages, best-value does present the government with its own peculiar challenges because of a lack of a precise understanding of what ‘best-value’ means. Hence, in this study, the author seeks to examine the concept of best-value and its application to Korean public building construction. To achieve the stated objectives, the author draws upon extant literature in ‘value’ procurement to critically examine the impact of ‘best-value’ concepts in Korean public building procurement. Data is obtained from a survey of 180 managers involved in the procurement and management of public buildings in Korea. Utilising ‘best-value’ criteria drawn from literature, the author employs Analytic Hierarchy Process (AHP) to weight ‘best-value’ criteria identified through the survey. Based on the results of the AHP exercise, the following are found; (i) value depends on the state of each individual building which can be defined from a ‘need’ perspective, (ii) the primary criteria for ‘best-value’ in Korea public construction projects were ‘serviceability’, ‘safety’, ‘comfort’, ‘environmental friendliness’, ‘economical feasibility’, and ‘artistry’ and finally that (?) the importance of each primary criteria was dependent on the building type
Viscoelastic and equilibrium shear properties of human meniscus: Relationships with tissue structure and composition
No full textThe meniscus is crucial in maintaining the knee function and protecting the joint from secondary pathologies, including osteoarthritis. Although most of the mechanical properties of human menisci have been characterized, to our knowledge, its dynamic shear properties have never been reported. Moreover, little is known about meniscal shear properties in relation to tissue structure and composition. This is crucial to understand mechanisms of meniscal injury, as well as, in regenerative medicine, for the design and development of tissue engineered scaffolds mimicking the native tissue. Hence, the objective of this study was to characterize the dynamic and equilibrium shear properties of human meniscus in relation to its anisotropy and composition. Specimens were prepared from the axial and the circumferential anatomical planes of medial and lateral menisci. Frequency sweeps and stress relaxation tests yielded storage (G′) and loss moduli (G′′), and equilibrium shear modulus (G). Correlations of moduli with water, glycosaminoglycans (GAGs), and collagen content were investigated. The meniscus exhibited viscoelastic behavior. Dynamic shear properties were related to tissue composition: negative correlations were found between G′, G′′ and G, and meniscal water content; positive correlations were found for G′ and G′′ with GAG and collagen (only in circumferential samples). Circumferential samples, with collagen fibers orthogonal to the shear plane, exhibited superior dynamic mechanical properties, with G′ ~70 kPa and G′′ ~10 kPa, compared to those of the axial plane ~15 kPa and ~1 kPa, respectively. Fiber orientation did not affect the values of G, which ranged from ~50 to ~100 kPa

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
The Wine Attributes with the Greatest Influence in the Process of Consumer Choice in Spain
No full textThe commercialisation of wine in Spain is problematic due to two concrete circumstances: the decrease in wine consumption because of a consumer shift toward substitute drinks and the greater presence of national and foreign wine in the interior market, which involves an increase in business competitiveness. The increase in competitiveness of quality Spanish wine depends on producing enterprises’ knowledge of wine consumer preferences so they can offer consumers what they demand. In order to respond to this matter and better adapt supply, 421 wine consumers were surveyed using the Best-Worst Scaling methodology. Various segmentations were also made by consumer income and age groups. The results indicate that the two main attributes which condition consumers in choosing wine are the region of origin and having tasted it previously. The region of origin attribute is valued in general by consumers over 34 years old who have a monthly family income above 1,500 €. The attribute of having tasted it before, which on many occasions is associated with the price attribute, is valued particularly by younger consumers and those with lower incomes.Consumer behaviour, Wine attributes, Food Marketing, Consumer/Household Economics,
