This study investigates 3883 articles published by researchers affiliated with Chiang Mai University in science and technology from January 2010 to December 2019 to test whether research team characteristics and collaboration patterns can determine a citation rate. Citations were retrieved from the Scopus database and compared with their (1) number of authors, (2) type of publication, (3) gender of authors, (4) SJR values, (5) country of international collaborators, (6) number of affiliated institutions, and (7) international diversity index. The findings were based on quantile regressions and indicated that the number of authors strongly influenced citations, which increases the likelihood of being cited. The citation advantage of being a foreign-first author only existed at the 0.25th quantile; however, the evidence of foreign-first author citation advantages or disadvantages for the moderate and very productive publications was not found. A significantly positive effect of SJR value on citations was found while being a female first author negatively impacted the citation rate. These findings can be used in the planning and managing process of producing scientific and technological research to improve the research quality, boost the research impact, and increase opportunities for research results to be utilized.

Business incubators (BIs) are important supporters for young businesses, since they provide firms with physical facilities and intangible support. Existing literature reviews focusing on BIs have neglected to consider individual factors in their success in favor of combining key performance measurements to identify their development targets. This systematic literature review thus aimed to combine studies that examined specific issues pertaining to BI performance and related key performance indicators to measure their activities. We conducted a systematic literature review based on two research questions: the first research question concerned critical factors for BIs’ performance; the second concerned their performance measurements. To ensure that we covered crucial factors and indicators of the latest generation of BIs, our systematic procedure included 74 studies published between 2005 and 2020 that were read in full and revealed ten critical factors that particularly emphasized financial resources and networking. We identified six categories for performance measurement, placing the greatest emphasis on the measurement of social capital. We recommend that academic researchers and BIs prioritize the intangible factors that constitute organizations’ hidden value. This review thus provides novel findings by identifying common critical factors for BIs’ performance and offering guidelines for performance measurement that consider BIs’ intangible assets and trends for future studies.

Portland cement (OPC) is one of the primary contributors accounted for climate change as a massive amount of Carbon dioxide is emitted to the atmosphere during its production processes. Geopolymer cement (GP), a green construction material, is therefore promoted to be an alternative cementitious binder to replace the consumption of that OPC. GP can be synthesized by mixing pozzolanic wastes (e.g., fly ash or slag) with alkaline solutions (e.g., NaOH and Na2SiO3). The mechanical properties of the geopolymer have been confirmed to be similar to or even better than OPC in the same testing conditions. However, the researches on GP have been mostly carrying out in just a laboratory scale, thus, the Laboratory grade of alkaline activators was commonly used. To make GP more realistic in practical works, the Industrial grade of alkaline activators was hence introduced. The results show that the usage of Industrial grade activators not only provides excellent mechanical properties to GP but also reduces its unit price to less than 20 percent of the conventional GP (GP with Laboratory-grade activator). By this approach, the confidence of expanding this green construction material, from Laboratory scale to In-field applications, is considerably increased.

This study explores a potential correlation between environmental and economic factors and the confirmed COVID-19 cases. This article uses official infection rate data and environmental and economic factors that may help accelerate transmissions, such as temperature, humidity, and GDP. Using statistical methods, i.e., ordinary least squares and quantile regression, our findings indicate that temperature, moisture, and island condition were the most influential explanatory variables. Nevertheless, the other factors, which are population density of a country, GDP, and country’s regime, are not statistically significant, indicating that those factors do not significantly explain changes in the confirmed COVID-19 cases.

In construction and building material sector, Lightweight Cement (LWC) has been receiving much more attention due to some of its advantages compared to other lightweight materials e.g. wood, foam and plastic. The method of incorporating tiny air bubbles into cementitious matrix for lightweight cement production is widely used as it could achieve good engineering properties with efficient production process. Conventional methods, Autoclaved Aerated Cement (AAC) and Portland cement-Cellular Lightweight Cement (CLC), use Portland cement as a main material which could lead to a huge disturbance to natural sources as well as release massive amount of carbon dioxide (CO2) to the atmosphere during its calcination. To achieve green construction material scheme, an attempt to utilize industrial wastes (by-products) as raw starting materials have been developing. One among those value-added approaches is OPC-less alkaline-activated cement from by-products, called Geopolymer technique. The main aim of this paper is to develop lightweight cement by using geopolymer technique with (CLC) method, called GP-CLC system, in order to optimize both economical aspects and engineering properties. The preliminary results show that the compressive strength of GP-CLC cannot reach that level of AAC system, but the strength was higher than the conventional OPC-CLC. The main challenge is that unit CO2 emission can be significantly reduce by using GP-CLC system as OPC consumption is replaced by by-product, fly ash.
