Purpose - Without question, globalization has presented different opportunities to entrepreneurs seeking to expand their companies in foreign markets. The aim of this study is to examine the relationship between entrepreneurial orientation, entrepreneurial activity, information internalization, and product differentiation in export oriented firms. As such, entrepreneurial activities are divided into exploitative and exploratory opportunities. These opportunities are crucial in improving firms' performance. Design/methodology - A structural questionnaire was developed using 21 factors/indicators from previous researches. The subjects of this study were recruited using convenience sampling in export SMEs in the Seoul Metropolitan Area. Data were collected through visits or e-mails from the export managers, executives, and CEOs of export SMEs in advance. 321 questionnaires were collected over a period of one month. 316 questionnaires were used in the final analysis. Findings - First, International Entrepreneurial-orientation (IE) has a positive effect on the exploration and exploitation of business opportunities. Second, the exploration and exploitation of business opportunities have a positive impact on information internalization. Third, information internalization has a significant effect on product differentiation and plays a mediating role in seeking opportunities, utilizing opportunities, and differentiating products. Originality/value - This study contributes to the development of academic discussions by explaining existing research gaps. First, there is currently a lack of research focusing precisely on the product differentiation capability of SMEs in manufacturing field in terms of IE. To bridge these gaps, we examined the entrepreneurial factors impact on product differentiation and tries to expand the discussion about the internationalization of SMEs, which were mainly focused on IT companies, and manufacturing companies. Second, there is no intuitive explanation regarding international entrepreneurial activity in terms of exploration and exploitation within existing. In this study, international entrepreneurship activities were classified in terms of exploration and exploitation.

Purpose - The purpose of this study was to examine the relationship between CEO name uncommonness and R&D intensity while focusing on CEO ownership and CEO tenure as moderators of the relationship. Design/methodology/approach - This study collected data from various American databases such as national data on given names from Social Security Administration, COMPUSTAT, and Execucomp. The sample of this study includes 2,494 (firm-year) observations from U.S. firms between 2005-2011. This study conducts Feasible Generalized Least Square (FGLS) regression analysis to test the hypotheses. Findings - First, we found CEO name uncommonness was positively related to R&D intensity. In other words, CEOs with unusual names prefer being distinctive by increasing R&D investments. Second, we examine the moderating roles of CEO characteristics (i.e., CEO ownership and tenure). The results show that CEO tenure strengthens the positive relationship between CEO name uncommonness and R&D intensity. Research implications or Originality - First, this study extends the CEO characteristics and R&D literature by investigating how CEO name uncommonness affects R&D intensity. In addition, our study also supports the intitutionalization of CEO power arguments by showing that CEOs with unusual names are more likely to pursue distinctive strategies when they have longer tenure. For practical implications, our results allow the investors to better predict corporate future R&D expenses. It suggests that ceteris paribus, CEOs with unusual names, vis-a-vis CEOs with common names, are more likely to increase R&D expenses.

Purpose - This article's aim is to examine how the utilization of existing and future decision-support systems will lead to a change in the auditing process. Research design, data, and methodology - An information system is a special decision-support system that combines information obtained from various sources and communicates among them to help in assessing appropriate complex financial decisions. This paper analyzes techniques such as data and text mining as components of decision-support systems to be used in the auditing process. Results - We present views about how existing decision-support systems will lead to a change in audits. Auditors, who currently collect significant data manually, will in the future move towards management through complex decision-support systems. Conclusions - Although some internal audit functions are integrated into systems of continuous monitoring, the use of such systems remains limited. Thus, instead of multiple decision-support systems, a unified decision-support system can be deployed for this that includes sensors integrated within a company in different contexts (e.g., production, sales, and accounting) that continually monitors violations of controls, unusual patterns, and unusual transactions.

The purpose of this paper is to study a framework on building and continuing consumer trust in mobile travel and tourism content (M-TTC). Trust development life cycle in e-commerce is a trust-oriented building flow of online consumer. Travel information and content in mobile commerce is a initiative and immature step in the ubiquitous era. Travel and tourism industry is information intensive and network business between the bricks and clicks, the public and private, and the virtual and physical. A framework of travel and tourism content in m-commerce based on Siau and Shen (2003) and in perspective of information cities by Ferguson, et al. (2004) proposes conceptual components to build information and content for continuous consumer trust. The main results of the paper by focus group research methodology focus on building a conceptual m-trust model of mobile content in travel and tourism industry. Additionally, it shows what the important factor is and how the trustworthy improves continuously to the public, mobile vendors, and technological aspects.

According to the Policy for ' e-Korea construction ' of Korean government, investment of information system during the Past decay are dramatically increasing. More than a half of this investment is cost of hardware infrastructure. So, accurate hardware sizing are essential for higher efficiency of investment. Accurate hardware sizing benefits are generally viewed in toms of the avoidance of excess equipment and lost opportunity costs by not being able to support business needs. Unfortunately, however, little research effort to make the hardware sizing methodology are doing. We propose a sizing method for information system in public sector. This method is determinated empirical study that are gathering and analyzing cases, making method and reviewing expert. Finally we are proposed calculating method for hardware components that is CPU, memory, internal and external disk according to the application system type which is OLTP, Web, WAS. Our study certainly will act as a catalyst for higher investment-efficiency of the future information programs in public sector.

In this paper we overview the literature on common features analysis of economic time series. Starting from the seminal contributions by Engle and Kozicki (1993) and Vahid and Engle (1993), we present and discuss the various notions that have been proposed to detect and model common cyclical features in macroeconometrics. In particular, we analyze in details the link between common cyclical features and the reduced-rank regression model. We also illustrate similarities and differences between the common features methodology and other popular types of multivariate time series modelling. Finally, we discuss some recent developments in this area, such as the implications of common features for univariate time series models and the analysis of common autocorrelation in medium-large dimensional systems.

Purpose: While prior research has identified ethical issues in marketing research, more research needs to identify specific ethical behaviors that marketing researchers should adopt. This research addresses this gap by identifying a few ethical behaviors that marketing researchers should consider. Research design, data and methodology: The present study has a justification to collect adequate textual data in the current literature using screening process based on the marketing ethics topics and themes, and ethical behaviors of marketing researchers. Results: Based on the literature analysis, a marketing ethics model, which included the principles of fairness, honesty, responsibility, and respect for stakeholders. Since the rise of e-commerce and technology, a growing demand for a method to analyze website user behavior has been growing. Researchers in the field of marketing are responding to this demand by creating innovative interactive platforms. Conclusions: The term "ethical practices in market research" refers to a collection of best practices that, when followed, increase the likelihood that the research carries out is ethical, fair, and accurate. Because there needs to be more theoretical work done on the topic, there should be more empirical studies on ethical behaviors in marketing research.

Purpose - The purpose of this study is to empirically investigate the degree of performance inconsistency among the Environmental, Social and Governance ratings. Design/methodology/approach - This study performs regression analysis using the widely used ESG ratings published by the Korea Institute of Corporate Governance and Sustainability. Findings - The results show that firms often do not show consistent performance across the Environmental, Social and Governance aspects, with excellent performance on one aspect but mediocre or poor performance on another. The paper also finds some degree of firm-level persistence in such performance inconsistency, suggesting that the traits of the firm and the industry the firm belongs to might influence whether a firm shows inconsistent performance across the three aspects. Research implications or Originality - This paper highlights the need for researchers and practitioners to understand the underlying behavior of the individual E, S and G ratings, instead of taking them as given, in order to properly design their analyses.
