Critical inquiry into emergent‐oriented curriculum practice     

Eunsook Hyun  J. Dan Marshall 《Journal of Early Childhood Teacher Education》2013,34(1):37-50

Abstract

This theoretical paper characterizes and explores emergent‐oriented curriculum practice through the experiences of an early childhood education (ECE) prospective teacher, in the context of the U.S., as she co‐constructs the meaning of emergent‐oriented curriculum with culturally diverse pre‐K (4–5‐year‐old) children during her field experience. The paper examines how the prospective teacher understood emergent learning, how she and the children created and shaped their curriculum, and what critical aspects pertain to emergent‐oriented curriculum work from the perspective of developmentally meaningful and culturally responsive practice.  相似文献

Label-free viscosity measurement of complex fluids using reversal flow switching manipulation in a microfluidic channel     

Yang Jun Kang  Jeongeun Ryu  Sang-Joon Lee 《Biomicrofluidics》2013,7(4)

The accurate viscosity measurement of complex fluids is essential for characterizing fluidic behaviors in blood vessels and in microfluidic channels of lab-on-a-chip devices. A microfluidic platform that accurately identifies biophysical properties of blood can be used as a promising tool for the early detections of cardiovascular and microcirculation diseases. In this study, a flow-switching phenomenon depending on hydrodynamic balancing in a microfluidic channel was adopted to conduct viscosity measurement of complex fluids with label-free operation. A microfluidic device for demonstrating this proposed method was designed to have two inlets for supplying the test and reference fluids, two side channels in parallel, and a junction channel connected to the midpoint of the two side channels. According to this proposed method, viscosities of various fluids with different phases (aqueous, oil, and blood) in relation to that of reference fluid were accurately determined by measuring the switching flow-rate ratio between the test and reference fluids, when a reverse flow of the test or reference fluid occurs in the junction channel. An analytical viscosity formula was derived to measure the viscosity of a test fluid in relation to that of the corresponding reference fluid using a discrete circuit model for the microfluidic device. The experimental analysis for evaluating the effects of various parameters on the performance of the proposed method revealed that the fluidic resistance ratio (R_JL/R_L, fluidic resistance in the junction channel (R_JL) to fluidic resistance in the side channel (R_L)) strongly affects the measurement accuracy. The microfluidic device with smaller R_JL/R_L values is helpful to measure accurately the viscosity of the test fluid. The proposed method accurately measured the viscosities of various fluids, including single-phase (Glycerin and plasma) and oil-water phase (oil vs. deionized water) fluids, compared with conventional methods. The proposed method was also successfully applied to measure viscosities of blood with varying hematocrits, chemically fixed RBC_S, and channel sizes. Based on these experimental results, the proposed method can be effectively used to measure the viscosities of various fluids easily, without any fluorescent labeling and tedious calibration procedures.  相似文献   

Using computer vision techniques on Instagram to link users’ personalities and genders to the features of their photos: An exploratory study     

Yunhwan Kim  Jang Hyun Kim 《Information processing & management》2018,54(6):1101-1114

Instagram and other photo-based social networking sites have emerged as a popular medium. Previous studies mainly focused on social media texts, but the current study deals with the relationships between the characteristics of Instagram users and the features of their photos. The Big Five personality traits and gender were employed as the variables for user characteristics. Content category, the number of faces, the emotions on the faces, and the pixel derived features were employed as the variables for photo characteristics. An online survey of 179 university students was conducted to measure user characteristics, and 25,394 photos in total were downloaded and analyzed from the respondents’ Instagram accounts. Results suggested that content category is associated with extraversion and gender of users. The number of faces is associated with extraversion, agreeableness, and openness of users. Extraversion, agreeableness, and openness of users were partly associated with emotions expressed on the faces in their photos. Correlations were observed among some pixel features and extraversion, agreeableness, conscientiousness, and gender of users. It was also observed that the Big Five personality traits, except for gender, can be predicted by above variables. Implications and limitations are discussed and suggestions for future research are suggested.  相似文献   

Enhanced stability criteria of neural networks with time-varying delays via a generalized free-weighting matrix integral inequality     

M.J. Park  S.H. Lee  O.M. Kwon  J.H. Ryu 《Journal of The Franklin Institute》2018,355(14):6531-6548

This paper deals with the problem of delay-dependent stability analysis for neural networks with time-varying delays. First, by constructing an augmented Lyapunov–Krasovskii functional and utilizing a generalized free-weighting matrix integral inequality, an improved stability criterion for the concerned network is derived in terms of linear matrix inequalities. Second, by considering a marginal augmented vector and modifying a Lyapunov–Krasovsii functional, a further enhanced stability criterion is presented. Third, a less conservative stability condition in which a relaxed inequality related to activation functions is added is introduced. Finally, three numerical examples are included to illustrate the advantage and validity of the proposed criteria.  相似文献   

Gun Violence and the Meaning of American Schools          下载免费PDF全文

Bryan R. Warnick  Sang Hyun Kim  Shannon Robinson 《Educational theory》2015,65(4):371-386

In the United States, targeted school shootings have become a distinct genre of violence. In this essay, Bryan Warnick, Sang Hyun Kim, and Shannon Robinson examine the social meanings that exist in American society that might contribute to this phenomenon, focusing on the question: “Why are schools conceptualized as appropriate places to enact this form of gun violence?” The authors analyze the social meaning of American schooling by using empirical data, everyday observations, films, and poetry, and then connect these points of meaning to stories of individual school shooters. Through this analysis, three aspects of school stand out. First, schools are places of both real and symbolic violence, where force and power often rule the day. Second, schools are places connected to expectations of hope and refuge, friendship and romance, and when these expectations are not met, bitter resentment flows against schools. Third, suburban schools are seen as places of expressive individualism, which, in rare cases, is manifest in terms of “expressive violence.” Together, these points of meaning can make schools, for some youth, seem like appropriate places to express violent intentions. The essay concludes by speculating about how this analysis can be applied to prevent school shootings.  相似文献

Understanding pickleball as a new leisure pursuit among older adults     

Jungsu Ryu  Hyunmin Yang  Amy Chan Hyung Kim  Kyung Min Kim 《Educational gerontology》2018,44(2-3):128-138

For older adults, participating in leisure activities has psychosocial benefits, increases social interactions, and promotes well-being. Among various leisure activities, pickleball is an activity that fosters positive social interaction and health benefits in older adults. Pickleball is regarded as one of the fastest growing sports in the USA, and it is reported to be popular among people of all ages, especially among older adults. The purpose of this study was to gather demographic details of older pickleball participants and elucidate the psychosocial benefits of playing the sport, such as life satisfaction, optimism, and social integration. To this end, we gathered information from 153 older adults who competed in pickleball tournaments. Multivariate analysis of variance and Hotelling’s T² test were used to compare the differences that emerged in experiential factors such as life satisfaction, optimism, and social integration among the different demographic characteristics. The results showed that life satisfaction was significantly different among the following three age groups: 50–59 years, 60–69 years, and ≥70 years. Results of Hotelling’s T² test showed a significant difference in social integration between male and female participants. The test also revealed a significant difference in terms of life satisfaction between retired and employed participants. The results suggest that playing pickleball can be an enriching leisure activity for retirees and may help them cope with the transition that retirement typically entails.  相似文献   

A hidden cost of strategic alliances under Schumpeterian dynamics     

Jeho Lee  Seung Ho Park  Young Ryu  Yoon-Suk Baik 《Research Policy》2010,39(2):229-238

Recently, proponents of interfirm R&D collaboration have emphasized its benefits. We develop a dynamic model of Schumpeterian competition to examine whether such collaboration is indeed beneficial in the long run. We find that interfirm R&D collaboration is more likely to be a losing strategy when partners form alliances mainly to reduce R&D costs. On the other hand, partners collaborating to seek synergy by accessing each other's complementary assets/capabilities are more likely to be successful. Our study suggests that firms should not use strategic alliances merely to reduce R&D costs in a catch-up situation or to avoid head-on competition with rivals.  相似文献
