R&D modes and firm performance in high-tech companies: A research based on cross-boundary ambidexterity and network structures

This paper draws on the cross-boundary ambidexterity theory to propose that four different R&D modes impact firm performance differently and that cooperative network structure moderates the above relationships. The theoretical model is tested by using financial and patent data of 587 high-tech firms for 10 consecutive years in China. We find that different R&D modes have different impacts on a firm’s financial and innovative performance, and network structure plays different moderating roles. Practically, this work guides high-tech enterprises to optimize their resource allocation, select the most appropriate R&D mode, and establish efficient cooperative networks

POTENCY AND CHALLENGES IN THE COMMERCIALIZATION OF BIOETHANOL FIRST AND SECOND GENERATION IN INDONESIA

This article introduces the current status of bioethanol commercialization in Indonesia. The review includes government policy and technical approach of bioethanol production regarding its efficient production methods. Molasses is the only first generation’s bioethanol raw material that is used for commercialization so far. Its potency is about 1.3 to 1.6 million tons a year and only 30 to 40 percent is used for bioethanol production. Meanwhile, a second-generation bioethanol pilot plant has been established and is still being optimized to improve its effectiveness. Currently, there is no report for the consumption of bioethanol for fuel even though there is a regulation from the Ministry of Energy and Mineral Resources No. 12/2015 for using 5 percent ethanol (E5) as a gasoline blending in the year 2020. Recently, Pertamina, a national energy company, has taken the initiative to launch the A20 (alcohol 20 percent that consists of 15 percent methanol and 5 percent ethanol) to overcome the still-high price of ethanol. Besides fuel grade ethanol (FGE), industrial grade ethanol (IGE) consumption was about 100 million liters in 2019. Second generation bioethanol potency is about five million liters only from 44 million tons of oil palm empty fruit bunch yearly. The production of bioethanol, both first and second generations, is still promising in the future

Methods Screenings took place from July 2012 to June 2013. Cognitive screening was incorporated into the annual health assessment for older adults with subjective memory complaints in a primary care setting. Two community nurses were trained to implement the screening using the Mini-Mental State Examination and Montreal Cognitive Assessment. Results Of 733 older adults, 495 (67.5%) reported having subjective memory complaints. Of the 249 individuals who participated in the cognitive screening, 102 (41%) had mild cognitive impairment, whereas 32 (12.9%) had cognitive impairment. A total of 80 participants (78.4%) with mild cognitive impairment agreed to participate in a memory support program. Participants with cognitive impairment were referred to specialists for further examination and diagnosis; only one reported that he had seen a specialist and had been diagnosed with dementia. Conclusions Incorporating cognitive screening into the annual health assessment for older adults with subjective memory complaints was feasible, though referral rates from primary care providers remained unchanged. The present study highlights the urgent need for simple screenings as well as community-based support services in primary care for older adults with cognitive or mild cognitive impairments

Under what institutional conditions do business groups enhance innovation performance?

This study examines the institutional mechanisms through which business groups impact innovation in emerging markets. Rather than merely viewing groups as the result of a weak institutional environment, this study proposes that there are complementary elements between groups and institutions, enabling groups to benefit from interactions with their institutional environment. Evidence from a large sample of Chinese firms indicates that the effects of groups on innovation are pronounced when the group is affiliated to a higher level government agency and when the level of region-specific marketization is higher. The findings point to the context-dependent nature of the innovation and the existence of both substitution and complementary effects between business groups and institutions

Frequency and Influencing Factors of Rubber Dam Usage in Tianjin: A Questionnaire Survey

Objective. To investigate the frequency and influencing factors of rubber dam usage for endodontic procedures among general dentistry practitioners and specialized practitioners (endodontist) in Tianjin. Methods. Three hundred questionnaires were distributed among practitioners from 3 different types of medical institutions in Tianjin. Data were collected and analysed using Chi-square tests. Results. There were 63.3% of respondents who have used rubber dam (response rate 82.7%, valid response rate 76.3%). However, only 0.4% and 3.1% of them recognized using rubber dam "every time" during caries direct restoration and root canal therapy, respectively. There was no significant difference in rubber dam usage between male and female practitioners. Among the respondents, practitioners with working experience between 5 and 10 years showed the highest usage rate (76.3%), while practitioners working more than 20 years showed the lowest (53.2%). The endodontists gained the highest and the most frequent usage rate and the best rubber dam technique mastering skills. Practitioners working in those stomatological departments of general hospitals showed the lowest rubber dam usage rate. Conclusions. The prevalence of rubber dam usage in Tianjin city is still low. The practitioner's gender, years of professional experience, general or specialized field, and the type of dental setting they work for are the factors that need to be considered during making policy and executing training
