An integrated actuating and sensing system for light-addressable potentiometric sensor (LAPS) and light-actuated AC electroosmosis (LACE) operation     

Hsin-Yin Peng  Chia-Ming Yang  Yu-Ping Chen  Hui-Ling Liu  Tsung-Cheng Chen  Dorota G. Pijanowska  Po-Yu Chu  Chia-Hsun Hsieh  Min-Hsien Wu 《Biomicrofluidics》2021,15(2)

To develop a lab on a chip (LOC) integrated with both sensor and actuator functions, a novel two-in-one system based on optical-driven manipulation and sensing in a microfluidics setup based on a hydrogenated amorphous silicon (a-Si:H) layer on an indium tin oxide/glass is first realized. A high-intensity discharge xenon lamp functioned as the light source, a chopper functioned as the modulated illumination for a certain frequency, and a self-designed optical path projected on the digital micromirror device controlled by the digital light processing module was established as the illumination input signal with the ability of dynamic movement of projected patterns. For light-addressable potentiometric sensor (LAPS) operation, alternating current (AC)-modulated illumination with a frequency of 800 Hz can be generated by the rotation speed of the chopper for photocurrent vs bias voltage characterization. The pH sensitivity, drift coefficient, and hysteresis width of the Si₃N₄ LAPS are 52.8 mV/pH, −3.2 mV/h, and 10.5 mV, respectively, which are comparable to the results from the conventional setup. With an identical two-in-one system, direct current illumination without chopper rotation and an AC bias voltage can be provided to an a-Si:H chip with a manipulation speed of 20 μm/s for magnetic beads with a diameter of 1 μm. The collection of magnetic beads by this light-actuated AC electroosmosis (LACE) operation at a frequency of 10 kHz can be easily realized. A fully customized design of an illumination path with less decay can be suggested to obtain a high efficiency of manipulation and a high signal-to-noise ratio of sensing. With this proposed setup, a potential LOC system based on LACE and LAPS is verified with the integration of a sensor and an actuator in a microfluidics setup for future point-of-care testing applications.  相似文献   

Identifying missing relevant patent citation links by using bibliographic coupling in LED illuminating technology     

Dar-Zen Chen  Mu-Hsuan Huang  Hui-Chen Hsieh  Chang-Pin Lin 《Journal of Informetrics》2011,5(3):400-412

This study uses bibliographic coupling to identify missing relevant patent links, in order to construct a comprehensive citation network. Missing citation links can be added by taking the missing relevant patent links into account. The Pareto principle is used to determine the threshold of bibliographic coupling strength, in order to identify the missing relevant patent links. Comparisons between the original patent citation network and the comprehensive patent citation network with the missing relevant patent links are illustrated at both the patent and assignee levels. Light emitting diode (LED) illuminating technology is chosen as the case study. The relationships between the patents and the assignees are obviously enhanced after adding the missing relevant patent links. The results show that the growth rates on both the total number and the average number of links have apparently improved at the patent level. At the assignee level, the number of linked assignees and the average number of links between two assignees are increased. The differences between the two citation networks are further examined by means of the Freeman vertex betweenness centrality and Johnson's hierarchical clustering. The patents with more new links to other patents have distinct results in terms of the Freeman vertex betweenness centrality. The enhancement of links among patents also results in different clustering.  相似文献   

Assessing web services of emerging economies in an Eastern country — Taiwan's e-government     

P.H. Hsieh  C.S. Huang  David C. Yen 《Government Information Quarterly》2013

Accessibility of much country-level information and many web services, originating from governments are a global standard. The governments of emerging economies in the eastern countries especially need to adopt, without undue delay, the advanced technologies for providing better web services to their citizens. However, consideration and evaluation of the effectiveness and efficiency of governments' web services is currently lacking in previous literature. Thus, this study first adopts a computational approach suggested in the literature to measure the effectiveness of Taiwan's established, city- and county-level (25 cities and counties, and 1411 governmental units) governments' websites. Then, by considering the IT-related input and output resources as suggested by the experts of e-government during several in-depth interviews, data envelopment analysis (DEA) evaluates the efficiency of Taiwan's governmental web services. This study reveals that the well-developed web services provided by Taiwan's government are apparent in two geographically dispersed cities (north and south) and one county in the northern region of Taiwan. In addition, six cities and counties appear to be ineffective and inefficient in providing web services to Taiwan's citizens due to their geographical remoteness from the capital and small regional populations. An additional finding confirms the significant effect of population size on Taiwanese services for e-government in each city and county. Finally, this study suggests applying more attention to website designs for different levels or regions of governments and building alternative communication channels for citizens with different backgrounds. Consequently, providing citizens' most-requested services becomes easier, and the resources' distribution becomes effective and efficient for those in different geographical locations. This study's findings represent a reference for providing better electronic publically accessible services, and a benchmark for scholars conducting further research in this area.  相似文献   

Women’s Involvement in Educational Psychology Journals from 1976 to 2004     

Joy?Evans  Peggy?Pei-Hsuan?Hsieh  Daniel?H.?RobinsonEmail author 《Educational Psychology Review》2005,17(3):263-271

Previously, Robinson, McKay, Katayama, and Fan (1998) examined women’s involvement in six educational psychology journals (American Educational Research Journal, Contemporary Educational Psychology, Educational Psychologist, Educational Psychology Review, Journal of Experimental Education, and Journal of Educational Psychology) from 1976 to 1996 and found that although women made gains as authors and editorial board members, they remained underrepresented as editors. In this Reflections on the Field article, we compare the Robinson et al. data with our more recent data. We found that from 1996 to 2004, the percentage of women members in education and psychology organizations has risen. Meanwhile, the percentage of women authors has remained stable; the percentage of women editorial board members has risen slightly; and the percentage of women editors has risen dramatically. We also found that the percentage of women authors and editorial board members lags slightly behind what would be expected based on organizational membership percentages for women. On the other hand, there are now more female editors than would be expected.  相似文献   

The effects of repeated maximal voluntary isokinetic eccentric exercise on recovery from muscle damage   总被引：5，自引：0，他引：5  

Chen TC  Hsieh SS 《Research quarterly for exercise and sport》2000,71(3):260-266

This study investigated whether performing repeated bouts of maximal voluntary isokinetic eccentric exercise (MAX1) on 3 (MAX3) and 6 days (MAX6) after the initial bout would produce significant changes in the indirect markers of muscle damage and total work. A secondary purpose was to determine whether participants' psychological maximal effort was equivalent to the physiological maximal effort during muscle soreness. Male university students were assigned randomly to a control group (n = 12) and a group that repeated the exercise (EX; n = 12). The MAX1 was 3 x 10 repetitions of the nondominant elbow flexors on the Cybex 6000 system at a speed of 60 deg/s. The EX group performed the same exercise 3 days and 6 days after MAX1. The range of motion and maximal isometric force (MIF), muscle soreness index, plasma creatine kinase, and glutamic-oxaloacetate transaminase activities were measured before and every 24 hr for 9 days after MAX1 for both groups. MIF was also assessed once before and immediately after each MAX for the EX group. There were no significant changes (p > .05) between the groups for all criterion measures, except for total amount of work (p < .05). It is concluded that strenuous voluntary isokinetic eccentric exercise performed with damaged muscles does not appear to exacerbate damage or influence the recovery process. Although individuals could perform repeated MAXs, the total work performed was significantly reduced. This has practical implications in strength training for coaches and athletes during muscle damage.  相似文献

Engaging Students with Art-Based S-R-C (Sense of Belonging,Resistance, and Coalition Building) Strategies for Anti-Racism     

Ryan Shin  Maria Lim  Kevin Hsieh 《The International Journal of Art & Design Education》2023,42(1):172-191

In this article, we discuss our struggles and efforts to respond to Asian American and Pacific Islander (AAPI) hate crimes and anti-Asian racism, as well as explore ways to address the issues of anti-Asian racism, violence, myths, and stereotypes in the art classroom. We researched and learned from contemporary Asian American artists, attended anti-racism virtual talks, and examined various anti-racism pedagogical approaches. As an outcome of our research to confront anti-racism, we developed S-R-C strategies to engage students with art-based anti-racism, which include facilitating a sense of belonging (S), resisting anti-Asian racism (R), and coalescing with other minority groups and allies (C). These strategies were developed to fully embrace the equity, diversity, and inclusivity of AAPI sequentially and holistically. This article also reports how we use the S-R-C strategies to guide our pre-service art teachers to confront anti-Asian racism and advocate for anti-racism teaching practices.  相似文献   

Motivation matters? The relationship among different types of learning motivation,engagement behaviors and learning outcomes of undergraduate students in Taiwan     

Tzu-Ling Hsieh 《Higher Education》2014,68(3):417-433

The purpose of this study is to understand predictors of different learning outcomes among various student background characteristics, types of learning motivation and engagement behaviors. 178 junior students were surveyed at a 4-year research university in Taiwan. The scales of motivation, engagement and perceived learning outcomes were adapted from the Motivated Strategies for Learning Questionnaire and the National Survey of Student Engagement College Student Report. Multiple hierarchical regression analysis was used in data analysis. Findings confirm that different student background characteristics and learning motivation can predict different learning outcomes. However, student engagement behaviors cannot significantly predict different types of learning outcomes when student background and learning motivation variables are included. This study also finds that student’s majors play an important role in explaining learning outcomes. Overall, the findings highlight the importance of learning motivation and suggest that instructors can provide students with more successful learning experiences to ensure more confidence in their learning abilities.  相似文献   

Gender Implications in Curriculum and Entrance Exam Grouping     

Hsieh Hsiao-Chin  Yang Chia-Ling 《Chinese Education & Society》2014,47(4):32-45

While access to higher education has reached gender parity in Taiwan, the phenomenon of gender segregation and stratification by fields of study and by division of labor persist. In this article, we trace the historical evolution of Taiwan's education system and data using large-scale educational databases to analyze the association of institutional factors and educational outcomes. Grouping in the college entrance examinations in the 1950s led to grouping in the high school curriculum, which, in turn, seems to have enlarged the mathematics performance gap between the natural sciences group and the social studies group, and extended to a performance gap between the two groups on the college entrance examination. Because men concentrate in science and engineering and women concentrate in humanities, the superiority of the former disciplines over the latter was consolidated along with the stereotype that male fields were better than female fields.  相似文献
