This study focuses on the application of multi-criteria performance measures based on the concept of equifinality to the calibration of the rainfall-runoff model TOPMODEL in a small deciduous forest catchment. The performance of each parameter set was evaluated by six performance measures, individually, and each set was identified as a behavioral or non-behavioral parameter set by a given behavioral acceptance threshold. Many behavioral parameter sets were scattered throughout the parameter space, and the range of model behavior and the sensitivity for each parameter varied considerably between the different performance measures. Sensitivity was very high in some parameters, and varied depending on the kind of performance measure as well. Compatibilities of behavioral parameter sets between different performance measures also varied, and very few parameter sets were selected to be used in making god predictions for all performance measures. Since different behavioral parameter sets with different likelihood weights were obtained for each performance measure, the decision on which performance measure to be used may be very important to achieve the goal of study. Therefore, one or more suitable performance measures should be selected depending on the environment and the goal of a study, and this may lead to decrease model uncertainty.

The importance of performance management has been on the rise, which led to public sectors utilizing BSC performance management system as a tool for adaptability, effectiveness, efficiency, and reorganizational abilities by the public sectors. However, due to lack of fairness of evaluation of performance management, it is difficult to expect high level of acceptance by organizations. Therefore, the purpose of the research is to analyze the acceptance of performance management system by organizations via stabilizing the system within the organization group. The research will utilize BSC performance management system of private sectors to introduce the system to public sectors to show the correlation between fairness of performance management and acceptance of performance management. Theoretical background for correlation between fairness of performance management and acceptance of performance management was created through reviews of documents and theories focusing on performance management. The methodology of the research was shaped through surveying members of organizations of public sectors. To analyze the findings of the data SPSS was exploited to find the statistics regarding frequency, degree of reliability, relevance, and recurrence. To summarize the research findings, the perception of performance management by organization members of public sectors shows positive correlation between fairness and acceptance of performance management, also acceptance of performance management shows positive correlation regards to organization performance. In spite of the findings of the research, the fairness and distribution of performance management was not great. Limitation occurred due to lack of perception and knowledge of performance management of respondents of the survey.

Research collaboration is regarded as core source to lead various innovations in all countries. This paper compares and analyzes the performance of Industry-University-Government Research Institutes (GRI) collaboration based on the four types of research collaborations; GRI-GRI, Industry-GRI, University-GRI and Industry-University-GRI. So this paper will show which collaboration type has the best work on each R&D step. We use four R&D steps; research, development, commercialization and overall. We also evaluate the performance of research collaboration of GRIs based on the collaboration types. In order to evaluate the performance of research collaboration, Data Envelopment Analysis (DEA) is employed for measuring the efficiency of GRIs in this paper. DEA is a non-parametric approach to measuring the relative efficiency of decision-making units (DMUs) with multiple inputs and outputs. The empirical results represent that the performance of collaboration with industry is generally superior to other collaboration types. These findings from this paper are expected to provide basic information for national collaboration strategy making.

The performance of scientific researchers has been studied from a number of different aspects, mostly in developed countries. This paper attempted to identify salient factors influencing scientific performance at individual level in a developing country. A model describing the productivity and performance of scientific researchers was developed. Four hypotheses were derived from the model; i) the degree of diversity of a researcher will affect the degree of his scientific performance, ii) the degree of dedication will affect the degree of his performance, iii) the degree of research pressure will affect the degree of his performance, and iv) the degree of satisfaction will affect the degree of his performance. Data were collected through questionnaires responded by 48 researchers from two research organizations. The results of data analysis supported the hypotheses in part. Specifically, diversity measured by the number of research areas was related to the productivity of research reports (p<0.05); research pressure influenced the average number of research papers (p<0.05). The results of hypothesis testing of the satisfaction showed mixed directions according to the indicators. Even though the results of data analysis did not support the hypotheses unanimously, probably due to the limitation of sample size, most of the descriptive analysis indicated that the direction of hypotheses in developed countries seemed to be similar in developing country too. However, more research efforts are needed to verify the research findings of developed countries in developing countries.

This article explores the relationship between the gender composition of scientific research teams and scientists' individual performance. The gender composition of research teams is an important feature of workplace settings and influences the way people interact and communicate; however, previous research has not directly examined its relationship with scientists' individual performance. Drawing on data collected on university faculties in China in 2016, this article tests several hypotheses about individual's performance in teams with different gender compositions. The results show that team gender composition has a clear gendered effect on scientists' individual performance. The effects of tokenism for women in men-majority teams is proven, but men in women-majority teams appear to be unaffected by tokenism. Moreover, the theories claiming that homogenous teams are more conducive to better individual performance than mixed teams are supported for men but not for women. The findings of this research suggest that recruiting more women into the scientific workforce may improve their performance and thereby help diminish the gender gap in performance. It also indicates that the Chinese preferential policies towards women in science formulated in recent years have had positive impacts. However, considering that more than half of the researchers in the survey are working in men-majority teams, the task of narrowing the gender gap in performance remains a challenge. Further work is needed to explore the tensions and benefits of working with the opposite gender.

At present, in the case of pump fast optimization, there is a problem of rapid, accurate and effective prediction of cavitation performance. In "A Cavitation Performance Prediction Method for Pumps PART1-Proposal and Feasibility" [1], a new cavitation performance prediction method is proposed, and the feasibility of this method is demonstrated in combination with experiments of a mixed flow pump. However, whether this method is applicable to vane pumps with different specific speeds and whether the prediction results of this method are accurate is still worthy of further study. Combined with the experimental results, the research evaluates the sensitivity and accuracy at different flow rates. For a certain operating condition, the method has better sensitivity to different flow rates. This is suitable for multi-parameter multi-objective optimization of pump impeller. For the test mixed flow pump, the method is more accurate when the area ratios are 13.718% and 13.826%. The cavitation vortex flow is obtained through high-speed camera, and the correlation between cavitation flow structure and cavitation performance is established to provide more scientific support for cavitation performance prediction. The method is not only suitable for cavitation performance prediction of the mixed flow pump, but also can be expanded to cavitation performance prediction of blade type hydraulic machinery, which will solve the problem of rapid prediction of hydraulic machinery cavitation performance.

The purpose of this study is to examine the effect of CEO's entrepreneurial orientation on innovation performance and business performance, and the mediating effect of innovation performance on the relationship between entrepreneurial orientation and business performance in small and medium-sized venture-enterprises (SMEs). To test the hypothesized relationships, we have conducted a survey of Korean SMEs. After excluding unanswered and untrustful item questionnaires, the final sample size for this study is 110 SMEs. The major findings of the empirical research are as follows. First, CEO's entrepreneurial orientation had apositive influence on innovation performance of a firm. Second, CEO's entrepreneurial orientation was positively related to business performance of a firm. Third, innovation performance had the partial mediating effect on the relationship between CEO's entrepreneurial orientation and business performance of a firm. That is, this result indicates that CEO's entrepreneurial orientation indirectly effects on business performance through innovation performance. Based on these findings, implications of the research findings are discussed, and recommendation for future research are provided.
