The purpose of this study is to provide a scale development process, in order to preliminarily address the reliability and validity of CEO transformational leadership, some key organizational factors, and product innovation performance constructs. Data for this study were collected from 264 manufacturing firms in Thailand. The measurement scales were pre-assessed using the Q-sort method, and exploratory factor analysis (EFA) was also conducted to assess the construct reliability and validity. This research established a theoretical framework of CEO transformational leadership, organizational factors including innovation strategy, organizational learning, innovation culture, new product development process, and product innovation performance. Q-sort technique and EFA can help improve the content validity and the construct validity of CEO transformational leadership, some key organizational factors, and product innovation performance. This study provided the initial developmental steps toward the building of a theoretical framework and scale measurement to allow better understanding of the constructs based on the context of firms in Thailand. This will allow researchers to bring new insights when exploring these constructs under differing operational conditions. The findings address additional steps required towards improved methodological aspects in terms of how to pre-validate and develop a measurement scale in various constructs within alternative domains.

The effects of LED light at 635 nm in fibroblast and osteoblast were investigate in fundamental changes as preliminary experiment. In this study, primary gum fibroblast cells and osteoblast cell line were cultured. After LED light irradiation, we found that fibroblast growth rate and cell proliferation are increased after irradiated by 630nm LED light. Optimum energy for wound healing is 0.34 J/cm2 at 630 nm. Optimum energy for proliferation is 0.67 J/cm2 at 630 nm. However, osteoblasts do not significantly and effectively response to LED light at 630 nm. © 2013 IEEE.

This systematic review paper integrates and analyzes previous empirical results between 2002-2012 to characterize the theories and variables that examine the leadership-innovation relationship. Even though there were many studies examining the effects of leadership on various types of innovation, the empirical results showing the leadership-product innovation relationship were scarce. Among a variety of styles or characteristics of leadership, transformational leadership was used most as explanatory variable to predict innovation. However, there was no single study revealing the positive effect of transformational leadership on product innovation. This article provides the pathway for researchers to further investigate the leadership-product innovation relationship. © 2012 IEEE.

The friction coefficient of the sulphurprevulcanized natural rubber (SPNR) film could be effectively reduced by deposition of poly(methyl methacrylate) (PMMA) particles. The nanoscale surface roughness of rubber, determined by atomic force microscope, was directly proportional to the particle size of PMMA particle at 12% surface coverage (Cs). The %Cs and surface roughness of the modified SPNR increased, while the friction coefficient decreased, with increasing PMMA latex concentration and immersion time. By using a mixture of latexes having both large and small sizes, the increase in the amount of small particles resulted in the better distribution of large particles deposited on the rubber surface. © 2009 Wiley Periodicals, Inc.

The purpose of this study is to examine the differences between corporate sponsored and self funded executive MBA student's e-learning behavior by using samples from one subject of an online MBA program. The findings from this research will help both educators and managers to better understand learners' behavior, especially those students sponsored by companies. The result showed that corporate sponsored students were less active than regular self-funded executive students in all activities based on either frequencies or time they spent for each activity. Moreover, the result from t-test revealed that there were significantly differences in terms of number of e-mail read, discussion board read and posted, and interaction behaviors between corporate sponsored and self-funded students. For cultural aspect, East Asian self funded students were more active than South Asian students in general. This study suggests that companies select and sponsor their employees who have strong motivation to get higher degree through e-learning environments. E-learning should be developed to serve different learning behaviors and cultures by trying other types of e-learning tools such as quiz or project work to better engage students. In addition, it is important to encourage corporate sponsored students to assume an active role in the e-learning environment.
