Construction and Validation of a Chinese Value of Learning Scale (CVLS)

The Chinese Value of Learning Scale (CVLS) is a 5-item instrument for assessing the value of learning in Chinese culture. The psychometric properties of CVLS were investigated in a convenient sample of 583 Chinese soon-to-be-aged adults in Hong Kong. CVLS possesses high internal consistency and exhibited satisfactory short-term test-retest reliability. CVLS also exhibited high face validity and mild convergent validity with other 48-item openness-to-experience scale (OTES) from Revised NEO Personality Inventory, and is significantly related to the past and actual learning experience. In view of its brevity and easy administration, CVLS offers a useful instrument to further investigate the value of learning in Chinese culture and its possible relationship with adults' learning behaviour.     

Endoscopic vein harvest in elective off-pump coronary artery bypass grafting

While traditional open vein harvest was related to postoperative wound complications, endoscopic vein harvest was developed to minimize the morbidity in the greater saphenous vein harvest procedure. In this study, these two procedures were compared for postoperative wound healing and long-term graft patency. We reviewed all consecutive patients undergoing elective off-pump coronary artery bypass grafting from January 2004 to December 2005 and collected data regarding wound complications and coronary events. Wound complications included dehiscence, excessive discharge, edema, altered sensation, cellulitis, hema-toma, pain scale, and superlicial and deep wound infection. Coronary events were defined as diagnosis of myocardial infarction during the first year's follow-up. A total of 392 patients were included in our series, among whom 44 were excluded from the study due to emergent operation, preoperative intra-aortic balloon pump support, or the greater saphenous vein varicose characteristic, 78 belonged to open vein harvest group, and 270 to endoscopic vein harvest group. Wound complications were significantly less in the endoscopic group (5.2%) compared to the open group (19.2%) (P=0.0002). There was no significant difference on preopera-tive risk factors, total operative time, or hospitalization days. During one-year follow-up, both the early and late graft patency rates were similar between the two groups. Endoscopic vein harvest is safe and effective, which carries less risk for wound complica-tions and is associated with better satisfaction and cosmetic result than the traditional greater saphenous vein harvest procedure. The endoscopic vein harvest also demonstrates a great long-term patency.     

The role of IT in achieving operational agility: A case study of Haier,China

Operational agility has increasingly become essential for survival and prosperity for contemporary organizations. Given its significant role in a turbulent business environment, this concept has garnered considerable research attention over the past ten years. However, due to the complex nature of operational agility, how to achieve this important organizaitonal capability is still not clearly understood. Thus the present study attempts to open this black box through examing a case study of Haier, the largest household appliances producer in China. The findings of this case highlight the significant role played by IT leveraging competence in achieving operational agility. It shows that IT leveraging competence helps enhance firm's ability to process information in a turbulent business environment, which results in information processing efficiency and information processing effectiveness. With the enhancement in the ability to process information, the focal firm is capable to sense and respond to market changes more readily.     

Child physical abuse and the related PTSD in Taiwan: The role of Chinese cultural background and victims' subjective reactions

Objective

This study aimed to investigate child physical abuse (CPA) while taking into account the more rigorous definitions of CPA in the Chinese societies. The prevalence of CPA and CPA-related PTSD were estimated, together with the examination of peri-traumatic subjective reactions and their impacts on PTSD.

Methods

In a Taiwanese sample of 1966 4th to 8th graders, the Chinese version of UCLA PTSD Reaction Index for DSM-IV (Steinberg, Brymer, Decker, & Pynoos, 2004) was used to investigate the lifetime exposure to CPA. A sub-sample of 236 traumatized CPA victims was examined with respect to related PTSD symptoms.

Results

Thirty-four percent of the children had been exposed to CPA. The estimated current prevalence of full and partial PTSD was 13.6% and 16.9%, respectively.

Conclusions

The current CPA prevalence was found to be higher than the Western countries, but lower than the previous findings in other East Asian societies. The full PTSD prevalence was close to the findings in the Western countries, whereas sub-clinical PTSD was less observed in Taiwan. Peri-traumatic subjective reactions, that is, Criterion A2 and perceived threat, were shown to be major predictors of PTSD symptom severity. The role of attitudes of child discipline in the Chinese societies in the prevalence of CPA and CPA-related PTSD is discussed.

Practice implications

By providing explicit epidemiological information of CPA and CPA-related PTSD in Taiwan, the current study extends our understanding of CPA and CPA-related PTSD more broadly from Western countries to the Eastern societies. By separately investigating CPA relating to different perpetrators, cross-study comparison is enhanced. In the current study, the significance of considering cultural background in defining CPA and examining CPA-related PTSD was pointed out. Meanwhile, the role of victims’ subjective reactions in the psychopathology of PTSD is highlighted. The findings and discussions could contribute for generating a more sophisticated clinical practice, especially with Asian or Chinese cases.     

Facial micro-expression states as an indicator for conceptual change in students' understanding of air pressure and boiling points

Utilizing facial recognition technology, the current study has attempted to predict the likelihood of student conceptual change with decision tree models based on the facial micro-expression states (FMES) students exhibited when they experience conceptual conflict. While conceptual change through conceptual conflicts in science education is a well-studied field, there is little research done on conceptual change through conceptual conflict in terms of students' facial expressions. As facial expressions are one of the most direct and immediate responses one can get during instruction and that facial expressions are often representations student's emotions, a link between students' FMES and learning was explored. Facial data was collected from 90 tenth graders. Only data from the 72 students who made incorrect predictions were analyzed in this study. The concept taught was the relationship between boiling point and air pressure. Through facial recognition software analysis and decision tree models, the current study found Surprised, Sad and Disgusted to be key FMES that could be used to predict student conceptual change in a conceptual conflict-based scenario.     

Course Management Systems and Blended Learning: An Innovative Learning Approach

This article utilizes Rogers ’ innovation‐decision process model (2003) and Beckman and Berry's innovation process model (2007) to create an innovative learning map that illustrates three learning methods (i.e., face‐to‐face learning, online learning, and blended learning) in two types of innovation (i.e., incremental innovation and radical innovation) that exhibits the behavior and dynamics on a two‐dimensional area of learning changes (i.e., change in learning model and change in technological infrastructure). The behavior and dynamics of face‐to‐face, online, and blended learning are depicted in the innovative learning map. Blended learning is identified as a radical innovative learning method in the innovative learning map. A course management system (CMS) is an information and communication technology (ICT) tool that can be used to facilitate and balance communication channel within a blended learning environment. Two propositions are proposed in this article: (1) CMS facilitates communication channel, enhances learning practice for learners and instructors, and is an enabler for blended learning; and (2) adopting CMS is suitable for blended learning practice. A case study to a college System Analysis and Design (SA&D) course reflects that the adoption of CMS in a blended learning environment is acceptable.
