Ideation is a process of generating new ideas or solutions using online crowd-sourcing technologies. This process has the potential to change the ways by which government agencies innovate and solve problems. Although increasingly more government agencies are implementing online ideation programs to tap into their employees' ideas and creativity, little is known about the unique challenges and effective practices of such programs. Thus, many government agencies are undergoing trial and error and often reinventing the wheel. This research aims to address this problem. By analyzing a focus group session and four cases of U.S. federal government ideation programs designed for their employees, this research identifies important organizational and technological challenges and effective practices. Furthermore, effective practices are grouped into different phases of ideation process and strategic vs. tactical levels to provide more meaningful and actionable insights. This research is an important step towards building a theoretical foundation for government ideation programs. The implications and limitations of this study are discussed.

The purpose of this study was to identify how characteristics of children, parents, and the family context relate to parental disciplinary practices and to examine the effects of cumulative positive variables on effective parental disciplinary practices. Subjects were 220 each mothers and fathers of 6-year-old children. Data were analyzed with correlation, multiple regression, and chi-square. Both Maternal and paternal disciplinary practices were correlated with child birth order, child emotionality, attention span and persistence, perceived social support and quality of life, and retrospective punitive parenting. Perceived quality of life and social support were predictive of maternal disciplinary practices and child emotionality was predictive of paternal disciplinary practices. Both mothers and fathers exposed to several positive variables were much more likely to exhibit effective disciplinary practices than parents exposed to no positive variables. Findings were generally consistent with Belsky's(1984) process model of parenting.

The purpose of this study was to identify which of the variables were associated with ineffective parental child-rearing practices and to examine the effects of cumulative risk factors on ineffective child-rearing practices. The subjects for this study consisted of 120 mothers and 120 fathers of two to six year old children attending a university child development laboratories. Self-report questionnaire were used to collect data on the following variables: 1) family backgrojnd characteristics; 2) child temperament; 3) quality of life; 4) social support; 5) intergenerational trasmission of parenting; and 6) parental disciplinary practices. Descriptive analysis, t-test, and chi-square analyses were used for data description and analysis. The major findings were as follows: 1) Mothers who perceived the child as being less emotional, more soothable, and who had higher levels of marital satisfaction and job satisfaction engaged in more effective child-rearing practices. 2) Fathers who perceived the child as being less emotional, and who have boys provided more effective child-rearing practices. 3) For both mothers and fathers, parents with higher levels of quality life, social support, and family income exhibited more effective child-rearing practices. 4) Parents exposed to several risk factors were much more likely to exhibit ineffective child-rearing practices than parents exposed to no risk factors. The results of this study indicate that the characteristics of the child, parent, and contextual factors all contribute to the parental child-rearing pracitices.

This primary purpose of this study was to analyze relations between child temperament and parental disciplinary practices. The subjects were 220 mothers and 220 fathers of kindergarten children. Child temperament was assessed using Colorado Childhood Temperament Inventory and parental disciplinary practices were measured by Parenting Scale. Resets indicated that (1) Fathers recognized their male children's temperament as more soothable and less emotional than those of female children whereas mothers recognized their male children's temperament as more active than those of female children. (2) Fathers recognized their children's temperament as more active than did mothers, but mothers recognized their children's temperament as more soothable than did fathers. (3) Children who were more sociable, less emotional, more sootable, and had longer attention span and persistence were related to more effective patemal disciplinary practices. (4) Children who were less emotional and had longer attention span and persistence were related to more effective maternal disciplinary practices. (5) Paternal disciplinary practices were explained by children's emotional temperament, whereas the best predictors of maternal disciplinary practices were children's emotional temperament and attention span and persistence.

The purpose of this study was to identify how characteristics of children, parents, family, and the extra context relate to disciplinary practices and to examine the cumulative effects of positive variables on effective disciplinary practices of employed and unemployed mothers. Disciplinary practices of both employed and unemployed mothers were correlated with number of child, husband support, parenting stress, social support, quality of life, and satisfaction of early childhood program. Parenting stress was the strongest predictor of disciplinary practices for both employed and unemployed mothers. Both employed and unemployed mothers exposed to several positive variables were more likely to exhibit effective disciplinary practices than mothers who were not.

BACKGROUND: Best management practices are often implemented to control nonpoint source pollutants. Best management practices need to be simulated and analyzed for effective Best management practices implementations. Filter strip is one of effective Best management practices in agricultural areas. METHODS AND RESULTS: Soil and Water Assessment Tool model was selected to explore the effectiveness of filter strip to control total phosphorous in Golji watershed. Soil and Water Assessment Tool model was calibrated for flow and total phosphorous by Sequential Uncertainty Fittin ver.2 algorithm provided in Soil and Water Assessment Tool-Calibration and Uncertainty Procedures. Three scenarios defined by filter strip width were applied. The filter strip width of 5 m was able to reduce the most amount of total phosphorous. In other words, the total phosphorous reduction by filter strip of 5 m was 28.0%, while the reduction was 17.5% by filter strip of 1 m. However, the reduction per unit filter strip width were 17.4%, 8.0%, and 4.5% for 1 m, 3 m, and 5 m of filter strips, respectively. CONCLUSION: Best management practices need to be simulated and analyzed so that the BMP scenario can be cost-effective. A large size of BMP might be able to control large amount of pollutants, however it would not be indicated as a cost-effective strategy.

The purpose of this study was to explore to what extent mothers and fathers differ in their disciplinary practices and to examine the relationships between quality of life and the parental disciplinary practices. The subjects of this study consisted of 220 parents(220 mothers and 220 fathers) of 5-6 years of children in Pusan. Descriptive analysis, correlation analysis, t-tests were used for data description and analysis. The major results were as follows: 1. There was a positive relationship between perceived quality of life by fathers and perceived quality of life by mothers. 2. There was a difference between fathers and mothers in relation to perceived quality of life. Fathers perceived their quality of life more highly than did mothers. 3. There were positive relations between parental educational level, household income and quality of life. 4. There were differences between fathers and mothers in relation to disciplinary practices. Fathers exhibited more effective disciplinary practices(including less overreactiveness and less verbosity) than did mothers. 5. There were no relations between parental educational level and disciplinary practices, but household income was only related to maternal disciplinary practices. 6. There were positive relations between quality of life and disciplinary practices. The higher parents perceived their quality of life, the more parents exhibited effective parental disciplinary practices.

This paper reports an empirical study on assessment of R&D best practices. The principles of quality management and their tools such as best practices or benchmarking have been so prevailing in the operational process that the R&D management recently consider extensive use of them for their innovation process. However, characteristics of the two processes may be different each other. Are the principles or the tools that were effective in the operational field still going to be effective in the innovative field? In order to answer the question, we statistically examine how R&D best practices contribute to the innovative performance. Upon literature review on technological innovation, we present a R&D process model whereby we set forth research hypotheses. Using data from 66 successful R&D efforts carried out among Korean firms mostly between 1999-2001, regression analyses reveal that best practices used in most stages throughout the R&D process are found not to significantly contribute to the innovative performance. Only those in technology strategy and prototyping stages are proven effective for technical and commercial performance respectively. Interestingly, efforts in a problem solving and improvement stage are counterproductive in the case of the innovation process. Discussions on our empirical observations are presented followed by some managerial implications.

Many agile practices have been suggested for software development flexible enough to adapt to a rapidly changing environment. However, too many agile practices hinder computer engineers from deciding which agile practices are suitable for a given project. They need guidelines of the benefits an agile practice provides for a project, and how many of its benefits are effective. Therefore, this study investigates IT experts' perspectives on each agile practice's effectiveness in their projects using a repertory grid technique. Based on an analysis of data collected from 23 Korean IT experts about 33 agile projects, we elicit 361 cognitive effects categorized into 30 benefits using content analysis. Next, we identify agile practices that are primarily used and recognized as positive and further examine what benefits many agile practices usually bring. Finally, we evaluate the level of benefits overall that each agile practice provides.

Despite the recent emphasis on mathematical communication, little practical guide has been provided for a teacher with what to do for orchestrating high-quality discussions in a mathematics classroom. This paper analyzed 20 elementary mathematics lessons which were recognized as effective instruction in Korea using an analytic framework with regard to 5 practices for orchestrating productive mathematics discussions (i.e., anticipating, monitoring, selecting, sequencing, & connecting) by Smith and Stein (2011) in terms of performance scales from Level 0 to 3. The results of this study showed that the most frequent levels were Level 1 including undesirable practices and Level 2 including insufficient practices. There were only one or two lessons per practice which were assessed as Level 3 of good performance. Specifically, Level 2 was the most frequent with regard to monitoring and selecting, whereas Level 1 was the most frequent as for the other practices. This paper provides some implications for co-ordinating productive mathematics discussions.
