Evolution Characteristics of Government-Industry-University Cooperative Innovation Network of Electronic Information Industry in Liaoning Province, China

It is important to optimize the cooperative innovation network for the improvement of economic competence and innovative power. Based on the patent information services platform, we obtain invention patent data for the electronic information industry in Liaoning from 1985 to 2015. This paper analyzes the cooperative innovation network structure, its spatiotemporal evolution and the triple helix relationship of government-industry-university(GIU) by using the social network analysis method and the triple helix theory as well as UCINet, ArcGIS and NetDraw. The empirical results show that: 1) the number of the subjects of the electronic information industry GIU cooperative innovation network in Liaoning demonstrates a gradual increase from 1985 to 2015, with the same trend in concentration. In terms of its subject and its centrality, the universities have a higher position, and the industries have a lower position,while the status of the government is still unclear. 2) The cooperative innovation network presents a core-periphery structure, and the polarization effect of innovation subjects tends to be obvious. There is certain distance-decay regularity in the cooperative innovation network, and a strong geographical proximity to cooperative innovation. 3) The compactness shows a downward trend as a whole. In terms of the extent of participation, the industries are better than the government but worse than the universities. This means that the cooperative innovation network of GIU in the electronic information industry in Liaoning is in the initial stage of formation.

Empirical Analysis on the Relation Between Electronic Industry Development and Energy Consumption

Data from 1996 to 2012 is used to conduct co-integration test, VAR model and Granger causality test in order to examine the relation between China＇ s electronic industry added-value and energy consumption. The result of co-integration test illustrates the long-term equilibrium of the relationship between the electronic industry development and energy consumption. The dynamic analysis of VAR model shows that there is a positive response from the economic growth of the electronics industry to energy consumption, while the impact of energy consumption on economic growth is a slightly negative response. It has been proved that the electronic industry development and energy consumption are mutual Granger causality. According to these conclusions, some suggestions are proposed in the end, including accelerating the development of China＇ s electronic industry to promote high-teeh electronic products, improving energy efficiency, enhancing research efficacy, creasing the effort for energy development and implementing rational energy policies.

An Analysis of Knowledge Sharing Approaches for Emerging-technology-based Strategic Alliances in Electronic Industry

Emerging technologies are now initiating new industries and transforming old ones with tremendous power. They are different games compared with established technologies with distinctive characteristics of knowledge management in knowledge-based and technological-innovation-based competition. How to obtain knowledge advantage and enhance competences by knowledge sharing for emerging-technology-based strategic alliances （ETBSA） is what we concern in this paper. On the basis of our previous work on emerging technologies＇ distinctive attributes, we counter the wide spread presumption that the primary purpose of strategic alliances is knowledge acquiring by means of learning. We offers new insight into the knowledge sharing approaches of ETBSAs - the knowledge integrating approach by which each member firm integrates its partner＇s complementary knowledge base into the products and services and maintains its own knowledge specialization at the same time. So that ETBSAs should plan and practice their knowledge sharing strategies from the angle of knowledge integrating rather than knowledge acquiring. A four-dimensional framework is developed to analyze the advantages and disadvantages of these two knowledge sharing approaches. Some cases in electronic industry are introduced to illustrate our point of view.

Corrosion in Control Systems Decrease the Lifetime of the Electronic Devices of the Industrial Plants of Mexicali,BC,Mexico

The principal factor to determine the economical value of the products manufactured in the electronics industry is due to the productive yielding. This is important for the cost of the articles fabricated in this type of industrial plants installed in Mexicali city, where around 80% of companies are, and which fabricate electronic devices and systems, or have industrial electronic systems and machines to their manufacturing process. Mexicalicity is located in theBaja CaliforniaStateof the northwest ofMexico, which is a border city with Calexico in theCaliforniaStateof the United States of America (USA). The region located in Mexicali, is a desert area. Geothermal plant is located in this area, which is an important industry and supplies electricity to this city and its valleys and some cities on southwest of United States for daily activities. This company emits hydrogen sulfide (H2S) as a main air pollutant that reacts with oxygen in the atmosphere, generating sulfur oxides (SOX). This chemical is dispersed to the city of Mexicali in which industrial plants are located with electronic control systems, and penetrates to indoor rooms. Those cause the corrosion process. The presence of corrosion leads to the deterioration of electrical connectors, the connections of electronic systems and the decreasing of the lifetime of these control systems. Other air pollutants that are considered as chemical agents which cause damage to materials used in the electronics industry, are the sulfurs and nitrogen oxides (NOX), emitted from the traffic vehicle and some industries. This causes the low productive yielding of electrical and electronic devices and systems used in the companies of this city, and is a major concern to specialized people, managers and owners. To analyze the productive yielding of electronic devices and systems installed in indoor of the electronics industry. For this reason, to know the principal causes of it, a study in three industrial plants, to determine the grade level of deterioration of the electronic control systems (ECS) used in the electronics industry of this city was made. The results showed that at major air pollution concentration detected by specialized methods, the lifetime of the ECS was decreased by the generation of corrosion in their electrical connectors and connections. This was caused for the levels of air pollutants mentioned above, than exceed the air quality standards in some periods of the year, added with the levels upper of relative humidity levels (RH) and temperatures of 85% and 25°C in winter and 80% 35°C in summer, being a main factor of this electrochemical phenomenon.

Nicotine Content in Electronic Cigarette Refill Solutions and Its Release in Aerosols

Electronic cigarette (EC) is a device that imitates conventional cigarettes, which vaporizes a solution, with or without nicotine. This study evaluates the nicotine levels in EC refill solutions, its release in aerosols and comparison to the amount stated on the label. Seventy-two (72) different EC refill solutions were obtained from local shops in Selangor, Malaysia consisting of 40 nicotine-containing (3 - 12 mg) and 32 nicotine-free (0 mg) solutions. Aerosols were obtained by using an air tight syringe connected to an EC device to draw aerosol through an XAD-4 sorbent tube that trapped the nicotine. Nicotine in solution and aerosol samples are analyzed using gas chromatography-mass spectrometry equipment. Quantified nicotine in 40 nicotine-containing solutions ranged from 0.224 - 17.306 mg/mL. Nicotine is detected in 3 of the 32 nicotine-free solutions. Percentage of nicotine released into aerosols from refill solutions varied from 0.54% - 28.2%. Out of the 40 samples, thirty-two (32) had nicotine content that violated by more than ±10% from the value on the label. In comparing the labels, 19 samples have 0.3% - 77% higher nicotine level and 13 samples have 0.2% - 96.3% lower nicotine content. The inconsistency between the labelled and true levels of nicotine content indicates that commercial information may be misleading. The presence of nicotine in the nicotine-free refill solutions and higher nicotine content in aerosols may be addictive and may have negative health effects on users.
