Purpose - We investigate how to increase consumer incentives to buy public offering funds, resulting in activating the public offering fund market. In particular, this study aims to find ways to expand diversity and to improve efficiency of public offering fund. The public fund market of Korea has been stagnant in recent years. However, the public offering fund market plays a very significant role in terms of consumer welfare. Since only a few wealthy investors can participate in the private equity market, the stagnation in the public offering fund market usually reduces the opportunity of consumer's buying funds thus ultimately affecting their future wealth. Research design, data, and methodology - To attain our purpose, the 'factor-based portfolio strategy' has been considered. It is an alternative portfolio strategy, which composites the advantages of the passive management and active management. For our empirical anaylsis, we used global stock distribution market data over the period of 1991 and 2016. Then we constructed portfolios based on firm-size, firm-value, and momentum. Finally, a regression model was set, then hypotheses were tested, analyzing the performances. Results - First, among the 15 factor-based portfolios of global, Europe, Asia-Pacific(ex Japan), US and Japan, in eight portfolios, positive excess returns are observed at 5% significance level. Further, there is another portfolio with positive excess return at 10% significance level. Second, most of the portfolios with significant excess performance show positive relationship with the market portfolio. However, the firm-value based portfolio in Asia-Pacific region shows no relationship, and the firm-value based portfolio in US shows negative relationship. Third, we confirmed that the two firm-value factor portfolios in Asia-Pacific region and US, not having positive relationship with market portfolio, provide significant excess returns. Conclusions - In this paper, we provide empirical evidences supporting that the factor-based portfolios expand the diversity of funds and improve the efficiency of investment performance. However, there is no guarantee that the efficiency will continue in the future. In addition, various constraints and costs must be considered. Nevertheless, our novel findings in the advanced financial market such as US and Asia-Pacific are very interesting and offers important implications.

Portfolio contains works that a learner has selected and collected to show growth and change for a limited time period. In terms of an assessment tool, portfolio provides the results of the student with authentic, reflective, interactive and individuals features. Also portfolio provides an opportunity of improvement about curriculum and engineering program. To apply the excellency of portfolio, the principle of portfolio should be understood well and reflected the real state of engineering education. The basic concept of portfolio as a assessment tool of engineering program outcomes was introduced. The example of a portfolio has been also suggested in the form of interactive e-based model. The model has been developed that the assessment for program outcomes was rather done from a student standpoint.

The use of multiple celebrity endorsement is a common practice in advertising campaigns. However, little research has been conducted on the effects of multiple celebrity endorsement. In particular, the current study is designed to delve into what factors influence the effects of multiple celebrity endorsement. Portfolio-brand fit, portfolio-celebrity fit, and portfolio celebrity-consumer fit are three factors that affect a consumer's attitude toward the ad, the endorsed brand, and the purchase intention in the context of multiple celebrity endorsement. Study findings suggest that portfolio-brand fit, portfolio-celebrity fit, and portfolio celebrity-consumer fit positively affect attitudes toward the ad. In addition, as shown in the modified model, covariance among these three variables was found. Practical and theoretical implications were also discussed.

Purpose: The purpose of this study was to examine the relationship between portfolio quality and financial sustainability of microfinance institutions in Kenya. Research Design, Data, and Methodology: The analysis was based on a panel dataset of 30 microfinance institutions for the period of 2010 to 2018. Data was obtained from the Microfinance information exchange (MIX) database, and it was analyzed through descriptive and inferential statistics with the aid of STATA. Based on the results of the Hausman test, the study adopted the fixed effect regression model to test the research hypothesis. Results: The study found that portfolio quality had a positive significant effect on financial sustainability of Microfinance institutions in Kenya (β= 0. 211; p-value < 0.05). For the control variables; firm age had a positive effect (β= 0.773; p-value <0.05), while firm size (β= -0. 749; p-value < 0.05) had a negative effect on financial sustainability. Conclusions: The study concluded that portfolio quality has an important influence on the financial sustainability of microfinance institution. The study recommends that managers of microfinance institutions should devise good collection policies to improve portfolio quality while lessening loan default rate. The portfolio quality may improve the overall profitability and enhance investor confidence in their strategic decision-making on refinancing.

Recently, the interest in Accreditation of Engineering Education, which aims at facilitating the development of engineering education and producing the high calibre of graduates in engineering schools, is increasing. The accreditation requires the students to prepare a portfolio which shows the educational achievements from all courses at the university. In the portfolio, educational activities and outputs of the student are included as a part of the achievements. Particularly, in the portfolio of design-related courses, outputs of the design the student has made until the graduation are accumulated. The outputs enable others to measure the design capability of the student and can be used as important reference materials when applying for employment or graduate school. In this paper, I propose a format of the portfolio for practical exercise courses, engineering design, and undergraduate design and explain the ways of the utilization of the portfolio.

The study empirically examines the effects of loan portfolio diversification on bank risk and return in the nascent banking market of Vietnam. Loan portfolio diversification is captured through the Hirschman-Herfindahl index and the Shannon Entropy with sectoral exposures. We access each bank's financial reports to collect the required data, especially the breakdown of sectoral loan portfolios, thus constituting a unique dataset. To compute bank return, we use the traditional accounting indicators, including return-on-assets, return-on-equity, and net-interest margin. For bank risk, we utilize the loan-loss provisions and non-performing loans relative to gross customer loans. Using a sample of 30 commercial banks over the period from 2008 to 2019 and the system generalized method of moments estimator for the dynamic panel, we indicate the downsides of portfolio diversification. Concretely, we observe that all diversification measures exhibit significantly negative signs in all regressions across different bank return proxies. At the same time, the estimates display the significant and positive impact of diversification on the non-performing loan ratio. Hence, sectoral loan portfolio diversification significantly hampers bank performance in both aspects of lower return and higher credit risk. The results are robust across a rich set of bank performance and portfolio diversification measures.
