Knowledge Sources of Innovation in a Small, Open Economy: The Case of Singapore
By tracing the flows of patent citation of prior patents and scientific journal articles, we investigate the sources of knowledge for innovation output in Singapore, a small, highly open economy that has traditionally been significantly dependent on foreign multinational corporations (MNCs). We found that the local production of new knowledge by indigenous Singaporean firms depends disproportionately on technological knowledge produced by MNCs with operational presence in Singapore and scientific knowledge generated by foreign universities. Locally produced new knowledge by indigenous firms and local universities constitute an insignificant, albeit rapidly growing, source for innovation in Singapore.innovation system, patent citation, Singapore, knowledge sources
Availability of Financing, Regulatory Business Costs and National Entrepreneurial Propensity
In this paper, we focus on two barriers to entry that may hinder the formation of new firms: capital requirements and regulatory business cost. The contribution of this paper is twofold: we compare the availability of different types of financing sources to address the issue of capital requirement and we utilise a new measure of business cost by constructing a composite index using data from the World Bankâs Doing Business Database. Using cross-sectional data on 37 countries that participated in the 2002 Global Entrepreneurship Monitor, we examine the effect of availability of financing and regulatory business costs on the propensity of three different types of entrepreneurial activity:opportunity-driven, necessity driven and high-growth potential new firm formation. The availability of three types of financing sources is analysed: traditional debt financing, venture capital financing, and informal investments. The findings show that only informal investments significantly influence the propensity to be entrepreneurs. Regulatory business costs were found to deter opportunity driven entrepreneurship, but had no impact on other types of entrepreneurial activity.entrepreneurial activity, financing, venture capital, informal investment, business cost
Singapore as an innovative city in East Asia : an explorative study of the perspectives of innovative industries
The city-state of Singapore has achieved rapid economic development in the past by its positioning as an efficient business hub in Asia. To remain competitive in the global knowledge economy, however, Singapore needs to move beyond efficiency by developing a strong"innovative"edge as well. This paper examines the challenges that Singapore faces in seeking to do so through an explorative survey of 40 firms from three innovative sectors: high-tech manufacturing industries, knowledge-intensive business services (KIBS), and creative content industries. Overall, while the survey confirms Singapore's continuing competitive strength in efficiency infrastructure, it also finds a favorable perception of Singapore as an innovative city. Indeed, many of the industry actors indicated that an efficient business infrastructure is a prerequisite for locating their innovative activities in Singapore, suggesting that the relationship between innovation and efficiency is complementary, rather than substitutional. While the study found that intellectual property and its protection are widely recognized by actors in all three sectors, interesting differences exist. In particular, intellectual property protection appears to be of greater concern to the high-tech research and development-intensive manufacturing sector and the creative contents sector than to the KIBS sector. Another interesting difference is that while competition in high-tech innovation tends to be global, competition in creative content tends to have a stronger local or regional dimension. Public policy in East Asia has traditionally emphasized the development of technological innovation capabilities in the manufacturing sector. In light of the findings, public policymakers may need to be more sensitive to the nuanced differences in policies needed to promote the new creative content industries and the associated supporting KIBS.ICT Policy and Strategies,Health Monitoring&Evaluation,Economic Theory&Research,Health Economics&Finance,Environmental Economics&Policies
Value in play: Games Items in Digital Environments
Game items have become valuable objects that can be traded by both players and game companies. However, valuable game items are typically misunderstood by the public as something unreal or unserious that should not be treated as something valuable. In this thesis, I examine how game items play a significant role as valuable objects in the culturally situated contexts of gameplay and beyond. In current mainstream discourses, the reasons why game items are so valuable to players can be understood from two main perspectives derived from two traditional approaches: the labour theory of value and the subjective theory of value. On the one hand, followers of the labour theory of value argue that the value of game items is manifest when players make efforts to obtain them. On the other hand, advocators of the subjective theory of value suggest that this value is given by playersâ subjective personal preferences. Although these two perspectives provide useful insights for understanding the value of game items, neither on its own is enough to provide sophisticated explanations for how the value of game items is created and used in different contexts of gameplay that involve much more complexity. This thesis argues that the value of game items is a result of the interplays between different factors involved with both the production and consumption processes in digital gaming. Drawing on theoretical concepts from different disciplines including media studies, economics, game design, performance studies, and sociology, this thesis argues that the value of game items should also be understood in three alternative contexts: game design; playersâ in-game social performance; and player groups. The role of game items as valuable objects therefore does not only originate from playersâ efforts and personal preferences, but is also created and affected by game mechanics and the strategies of game companies, the way players perform their online identities, and the influence of player groups in digital environments. This thesis suggests that a multi-perspective and an interdisciplinary approach are appropriate and necessary to provide a more comprehensive picture of how game items have become significantly valuable
Biochemical and Microbiological Characteristics of Ground Beef in Modified Atmosphere Packaging With Gas Exchange.
The shelf-life of ground beef in modified atmosphere packaging (MAP) with exchange of gases before retail display was compared with conventional vacuum packaging (VP) and overwrapping with polyvinylchloride film (PVC) for display. Ground beef patties in MAP with distribution gases of 20% \rm N\sb2:80\%\ CO\sb2,\ 50\%\ N\sb2:50\%\ CO\sb2,\ or\ 80\%\ N\sb2:20\%\ CO\sb2 and display gases of 80% \rm O\sb2:20\%\ CO\sb2,\ 50\%\ O\sb2:20\%\ CO\sb2:30\%\ N\sb2, or 20% \rm O\sb2:20\%\ CO\sb2:60\%\ N\sb2 had decreased weight loss, microorganism growth rate, metmyoglobin formation, and color degradation compared with patties in VP-PVC. Increased CO\sb2 during distribution retarded microbial growth. Display gas mixtures with higher O\sb2 increased redness (HunterLab a values), decreased metmyoglobin formation, and minimally increased lipid oxidation during six days of retail display. Ground beef patties in 50% \rm N\sb2:50\%\ CO\sb2 for distribution and 80% \rm O\sb2:20\%\ CO\sb2 for display provided optimal shelf-life and color in this study. An abusive display temperature (15\sp\circC) decreased shelf-life of ground beef patties in VP-PVC and MAP (50% \rm N\sb2:50\%\ CO\sb2 exchanged for 80% \rm O\sb2:20\%\ CO\sb2) to 1 and 3 days compared with 3 and more than 4 days with 7\sp\circC display. Abusive display temperatures increased incidences of pathogenic microorganism species in MAP samples. Lipid peroxidation in ground beef and isolated microsomal fractions increased time after packaging in both VP-PVC and MAP with 50% \rm N\sb2:50\%\ O\sb2 exchanged for 80% \rm O\sb2:20\%\ CO\sb2. Enzymic lipid peroxidation activity of microsomes extracted from the ground beef at each sampling time increased with extended display time after gas exchange, but lipid oxidation in beef patties remained constant during retail display. High \rm O\sb2 display gas increased HunterLab a values and reduced metmyoglobin formation in gas exchanged MAP samples without increasing lipid oxidation. MAP with gas exchange increased shelf-life compared with conventional VP for distribution and air permeable retail packaging for ground beef, but temperature is an important control of pathogenic microorganism growth
The Impact of R&D on the Singapore Economy:An Empirical Evaluation
Much of the literature on the impact of R&D on economic performance is founded on the advanced countries, where the intensity of R&D expenditure has been relatively high and stable for many years. In this paper, we provide empirical estimates of the impact of R&D on the economic growth of a Newly Industrialised Economy, Singapore, where R&D expenditure intensity has been low initially, bur rising rapidly in recent years. The Cobb-Douglas based analysis provided empirical evidence that R&D investment in Singapore had a significant impact on its total factor productivity performance in the last 20 years and established a long-term equilibrium relationship between R&D investments and TFP. However, compared to the OECD nations, the impact of R&D investment on economic growth in Singapore is not as strong, as evidenced by lower estimated elasticity values. The long run elasticity of output with respect to R&D was computed to be 8.1% for Singapore compared to long run elasticities of over 10% estimated by other researchers for OECD countries. This suggests that Singapore still has some way to go in catching up with the advanced nations in terms of R&D productivity. This not only means increasing the level of R&D intensity in Singapore but also more efficient exploitation of domestic R&D activity.Economic Growth, R&D Expenditure, Total Factor Productivity
Effects of thermal and mechanical fatigue on the flexural strength of G40-600/PMR-15 cross-ply laminates
The effects of thermal and mechanical fatigue on the flexural strength of G40-600/PMR-15 cross-ply laminates with ply orientation of (0(2),90(2))2S and (90(2),0(2))2S are examined. The relative importance of shear and tensile stresses is examined by varying the span-to-depth ratios of flexural test specimens from 8 to 45. Acoustic emission signals are measured during the flexural tests in order to monitor the initiation and growth of damage. Optical microscopy is used to examine specimens for resin cracking, delamination, and fiber breaks after testing. Transverse matrix cracks and delaminations occur in all specimens, regardless of ply orientation, span-to-depth ratio, or previous exposure of specimens to thermal and mechanical fatigue. A small amount of fiber tensile fracture occurs in the outer 0 deg ply of specimens with high span-to-depth ratios. Because of the complex failure modes, the flexural test results represent the 'apparent' strengths rather than the true flexural or shear strengths for these cross-ply laminates. Thermal cycling of specimens prior to flexural testing does not reduce the apparent flexural strength or change the mode of failure. However, fewer acoustic events are recorded at all strains during flexural testing of specimens exposed to prior thermal cycling. High temperature thermal cycling (32 to 260 C, 100 cycles) causes a greater reduction in acoustic events than low temperature thermal cycling (-85 to +85 C, 500 cycles). Mechanical cycling (0 to 50 percent of the flexural strength, 100 cycles) has a similar effect, except that acoustic events are reduced only at strains less than the maximum strain applied during flexural fatigue
