    Adaptive Two-stage Spectrum Sensing under Noise Uncertainty in Cognitive Radio Networks 

    Kornkamol Thakulsukannant (2016)

    To utilize licensed spectrum bands efficiently, spectrum sensing needs to be accurate and fast. The occurrence of noise uncertainty and the lower in received PU signal power due to the distance between the transmitter and the receiver, path loss, are the main challenges that has a great impact on the accuracy of spectrum sensing. In this paper, we propose a new scheme of two-stage spectrum sensing, “Adaptive Two-stage Spectrum Sensing (ATSS)”, under noise uncertainty environment. ATSS is a modified of a conventional two-stage spectrum sensing ...

    Alternative Modes of Export Entry for SMEs from Emerging Economies 

    Amonrat Thoumrungroje (2013)

    The primary purpose of this study is to investigate the specific issue of modes of export entry of small and medium-sized enterprises (SMEs) that originate from emerging economies. Four theoretical frameworks on the process of internationalization (i.e. FDI, stage models, network perspective, and organizational capability perspective) are reviewed with respect to the internationalization of SMEs. Direct and indirect exporting are compared based on transaction cost analysis (TCA) and the network perspective. Problems arising from the use of extant ...

    Content Analysis of Wiki Discussions for knowledge Construction: Opportunities and Challenges 

    Vasa Buraphadeja (2012)

    Research on several aspects of asynchronous online discussions in online and hybrid courses has been successfully conducted using content analysis in the past. With the increase in Web 2.0 and social media use in education, research on knowledge construction within newer virtual environments like blogs or wikis is just emerging. This study applies a well-known model of content analysis for knowledge construction to an educational wiki environment. Twelve graduate students’ contributions to a wiki in a 14-week on-campus course on Web 2.0 technologies ...

    The Contingent Role of Customer Orientation and Entrepreneurial Orientation on Product Innovation and Performance 

    Amonrat Thoumrungroje; Racela, Olimpia C. (2013)

    This paper synthesizes marketing and entrepreneurship literature and postulates the complementary nature of a customer orientation with that of an entrepreneurial orientation, then explores their relationships with product innovation and performance. A path analysis was used to test the hypotheses based on data collected from a sample of 159 strategic business units in 15 different industries. The results show that an entrepreneurial orientation does not have a relationship with product innovation unless it is coupled with the complementary effect ...

    Corporate Governance, Violations and Market Reactions 

    Visit Phunnarungsi (2013)

    We test the relation between firm-level corporate governance and the market reaction to announcements of violations of rules and regulations by Thai listed firms. We find no significant difference in market reaction when firms with high and low governance scores commit violations. We do find a larger negative abnormal return when firms with low past violation records violate the rules. The market reaction is especially strong, − 8.1% on average, when firms with low past violations and low governance scores commit violations. The evidence suggests ...

    A Cross-Vergence of Consumer Preferences: An Empirical Study of Ethnic Subgroups in Thailand 

    Amonrat Thoumrungroje (2012)

    Building on Bandura’s (2002) social cognitive theory and Phinney’s (1993) three-stage model of ethnic formation, this study explores the trends towards cross-vergence of consumers’ demand in the globalization era. The results from an exploratory factor analysis aiming to identify the underlying benefits that consumers of three different ethnic subgroups in Thailand have towards a non-ethnic consumer product confirms the crossvergence thesis. Thus, both sociology and psychology literature complements each other in explaining both the ...

    Amonrat Thoumrungroje (2012)

    The use of foreign branding has become a popular strategy to employ on local products. A betweensubjects experimental design involving a total of 80 Thai participants was conducted to examine the effects of foreign branding on consumers product evaluations and attitudes toward the brand. Foreign branding was manipulated as English and Thai pronunciation of six fictitious brand names.

    The influence of passion and empowerment on organizational citizenship behavior of teachers mediated by organizational commitment 

    Varam, Parvathy (2016)

    The present research aims to study the direct and indirect influence of passion and empowerment on organizational citizenship behavior of teachers in a private university in Thailand mediated by organizational commitment. The sample comprises 124 teachers teaching in the university and the Organizational Citizenship Behavior Scale, adapted by Podsakoff and Mackenzie (1990), Passion Scale, developed by Vallerand, Carbonneau, Fernet and Guay (2008), School Participant Empowerment Scale (SPES) developed by Short and Rinehart (1992) and Organizational ...

    Influences of Destination Image on Thai Students’ Perceived Value and Travel Motivation on the Work and Travel Program 

    Nucharee Supatn; Chanita Jiratchot (2015)

    Work and Travel is known as a program that brings students to work abroad during summer session. As the program is operated by the private firms, students' perception and reaction on the program are important in term of the prediction on the sustainability of the business. This research aims to study the relationships between destination image, perceived benefits and perceived monetary and non-monetary cost,which are time, effort, and possible risk, on perceived value and travel motivation. Questionnaire suvery was designed where 351 sets of ...

    Market Timing with GEYR in Emerging Stock Market: The Evidence from Stock Exchange of Thailand 

    Nopphon Tangjitprom (2012)

    This paper aims to examine whether the market timing strategy with Gilt-Equity Yield Ratio or GEYR can create abnormal returns in Thai Stock market. The trading rules using GEYR are established and switching strategies between bonds and equities are implemented. The out-of-sample profitability of these switching strategies compared with the simple buy-and-hold strategy. The result shows that switching strategies using GEYR can provide higher return but lower risk than buy-and-hold equity portfolio, even after the transactions costs are considered. ...

    Patent Alchemy: The Market for Technology in US History 

    Dhanoos Sutthiphisal (2013-03)

    The literature on inventors has traditionally focused on entrepreneurs who exploited their ideas in their own businesses and on researchers who worked in large firms' R&D laboratories. For most of US history, however, it was as common for inventors to profit from their ideas by selling off or licensing the patent rights. This article traces the different ways in which inventors resolved the information problems involved in marketing their patents. We focus in particular on the patent attorneys who emerged during the last third of the nineteenth ...

    Practical Programming Tutorial of Two Dimensional Discrete Fourier Transform (DFT) Based on MATLAB® for Both 2D Signals and Images 

    Kornkamol Thakulsukannant (2016)

    The two-dimensional (2-D) Discrete Fourier Transform (DFT) and Inverse Discrete Fourier Transform (IDFT) represent mathematical models for 2-D signals (such as digital images and digital videos) in the frequency and spatial domains, respectively. Digital Image Processing (DIP) has been implemented globally over the past two decades. Thus, 2-D Discrete Fourier Transform (2-D DFT) is essential in terms of representing mathematical models and analyzing 2-D signals and systems. In light of its importance, this article presents a tutorial for ...

    Propensity to Pay Dividends and Catering Incentives in Thailand 

    Nopphon Tangjitprom (2013)

    The paper aims to measure the investors' demand for dividends in Thailand and examine whether the demand for dividends could link to the firms' decisions to pay dividends. The positive dividend premiums show that investors in Thailand having the preference towards dividend, even though the dividend incomes could be taxed more heavily than capital gain in Thailand. After controlling the effect of 1997 Asian Crisis, there is the evidence to support the catering theory of dividends.
