This study was designed to explore the effects of problem-based learning (PBL) strategies on the attitudes of female senior
high school students toward integrated knowledge learning in science, technology, engineering, and mathematics (STEM). Content
analysis and focus group methods were adopted as the research processes. Data and information about the STEM internet platform,
an attitude scale and the contents of interviews were also collected for analysis. The subjects were 10th grade students at
a girls’ senior high school who volunteered to organize teams for a Solar Electric Trolley Contest. A total of 40 students
were grouped into 18 teams. The results of the study indicate: (1) that PBL strategies can be helpful in enhancing students’
attitudes toward STEM learning and the exploration of future career choices; (2) that the PBL teaching strategy helped to
lead students step by step toward completing the contest’s mission and to experience the meaning of integrated STEM knowledge;
(3) that not only that students can actively apply engineering and science knowledge, but also that students tend to gain
more solid science and mathematics knowledge through STEM learning in PBL; and (4) that PBL can enhance students’ abilities
and provide them experiences related to knowledge integration and application. Therefore, it is recommended that the curriculum
at the girls’ senior high school include more content related to specialty subjects to enhance their technological capabilities.
In addition, a learning mechanism should be offered to aid advisers or teachers in strengthening students’ integrated and
systematic knowledge about STEM. 相似文献

The purpose of the study was to explore a learning behavioral model of project-based learning (PBL) for senior high school
students in the context of STEM (science, technology, engineering, and mathematics). Using “audio speakers” as the project
theme, a series of tasks were designed to be solved using STEM knowledge via an online platform and student group discussions.
A total of 84 volunteer students from a senior high school and a vocational school in Pingtung, Taiwan, were divided into
21 groups. Text analysis and questionnaire survey were administered. Data sources were the participants’ information collected
via the STEM online platform and the questionnaire survey regarding STEM in PBL. The findings of the study are as follows:
(1) the learning behavioral model for STEM in PBL showed a positive influence on students’ behavior in the form of cognition
and behavioral intentions. In addition, cognition and behavioral intentions were positively influenced by attitude. The overall
model fit was positive and could effectively explain senior high school and vocational school students’ learning behavior
as related to STEM in PBL; (2) according to the results of the analysis of STEM from the online platform, students displayed
a positive attitude, attained integrated conceptual and procedural knowledge, and demonstrated active behavioral intentions
through STEM in PBL. In addition, the students’ creative and organized project outcomes revealed the effects of their behavior. 相似文献

The transition economies are known to have quite different market structures from the market economies. State-owned banks
accounts for a major part of the financial sector in East European countries before the transition period. Since the input
prices of the sector are frequently under the control of those governments, the misallocated resources may incur the loss
of economic efficiency. This paper attempts to gauge the technical and allocative efficiency using unbalanced panel data of
340 banks from 14 transition countries under the framework of the Fourier flexible shadow cost function. Accommodating technical
and allocative efficiencies simultaneously, as suggested by Atkinson and Cornwell (Int Econ Rev 35:231–243, 1994a) and Kumbhakar and Wang (J Econom 134:317–340, 2006a), avoids potential specification errors and leads to consistent parameter estimates. The average total cost savings resulting
from greater technical and allocative efficiency are around 28.31 and 7.13%, respectively. Foreign-owned banks are found to
be the most economically efficient. The enforcement of financial liberalization does gradually improve upon the sample banks’
technical efficiency. The allocative inefficiency arises from over capitalization and excess funds. Scale diseconomies appear
to prevail in the sample states with a few exceptions. 相似文献

This article describes the financial liberalization process in Taiwan and evaluates the effects of foreign institutional investors on Taiwan's stock market. Gradual liberalization allowed Taiwan to reap the benefits while reducing the harmful impacts of foreign participation during the Asian financial crisis. Overall, the liberalization policies proved to be effective as the stock market has become more stable and efficient. Foreign institutional investors contribute significant growth to the Taiwan stock market, and will continue to play a sizeable role in its future development. 相似文献

Based on the concept of experience economy, this study starts off by proposing that goods, services, and experiences are dimensions of experience-oriented service functions, illustrating an integrated approach which adopts the basic Kano model and customer satisfaction coefficients matrix to categorize and prioritize experience-oriented service functions. An empirical study was then conducted to explore customer need attributes for digital television (DTV) applications. As a result, 445 samples in Taiwan are collected and analyzed, showing different segments have different need attributes. In addition, a comparative analysis of experience-oriented customer needs for experienced and inexperienced users was applied in order to provide differentiated and continuous competitiveness during different stages of the product life cycle; then the result was used as a reference for future development of experience-oriented service functions. 相似文献

Wetlands provide many functions that are both economic and recreational and are valuable in terms of their ecological diversity, while at the same time being nonmarket value products. The purpose of this study is to estimate the optimal wetland rental through estimations of both the demand and supply functions in relation to wetland. The wetland supply function is directly estimated based on the data provided by the owners of the wetland, while the estimation of the wetland input demand function involves using the bootstrapping and contingent visitation approaches. Such estimation approaches could also be applied to other nonmarket value products that give rise to environmental externalities. The estimation of rental fee could provide a long-term leasing contract that gives the landlord with a particular rent to lease their lands to support a wetland eco-tourism park to maintain wetland for substantial management. Several environmental management policy implications are also addressed. 相似文献

Exploiting existing assets and exploring new assets are two major and often concurrent forces driving firms to invest abroad. Moving beyond prior attention to their separate effects on foreign ownership decisions, this study examines their integrative impact. I develop hypotheses aligning a set of firm‐specific advantages with asset‐seeking motives, and test these relationships on a sample of Taiwanese overseas investments. I find that wholly‐owned subsidiaries are preferred to joint ventures when multinationals are able to tap into host innovatory dynamism by employing extant technological capabilities and to access local natural resources by leveraging corporate scales. Nonetheless, multinationals face difficulties in deploying marketing knowledge in different contexts and thus are more likely to choose joint ventures for an aggressive foreign market entry.

The decision-making of investors is highly influenced by their feelings. According to behavioural finance, investor greed and fear would form irrational behaviour and affect their portfolio allocation. Although well-known mechanical investment strategy of dollar cost averaging (DCA) and value averaging (VA) could eliminate the problems of when to purchase, there are still some disadvantages to consider. For example, using a DCA strategy may be able to decrease volatility in portfolio so as to not effect investment decision, but it gives no rule for selling and may increase the opportunity cost of time if investors start deducted at peak prices. On the other hand, VA gives more aggressive sell signals to control the value of the portfolio to the level desired, but the investor may not have enough money purchase of a large number of shares in sharp decline period. Therefore, we use VA as main strategy and Bollinger Band as assist indicator for check for volatility for entry or exit. Through analysis and simulation, the new strategy we design does improve the performance during both bull and bear market periods. 相似文献

The rapid development of the internet has brought huge benefits and social impacts; however, internet security has also become a great problem for users, since traditional approaches to packet classification cannot achieve satisfactory detection performance due to their low accuracy and efficiency. In this paper, a new stateful packet inspection method is introduced, which can be embedded in the network gateway and used by a streaming application detection system. This new detection method leverages the inexact automaton approach, using part of the header field and part of the application layer data of a packet. Based on this approach, an advanced detection system is proposed for streaming applications. The workflow of the system involves two stages: the training stage and the detection stage. In the training stage, the system initially captures characteristic patterns from a set of application packet flows. After this training is completed, the detection stage allows the user to detect the target application by capturing new application flows. This new detection approach is also evaluated using experimental analysis; the results of this analysis show that this new approach not only simplifies the management of the state detection system, but also improves the accuracy of data flow detection, making it feasible for real-world network applications. 相似文献

In science and technology industries, innovative products are launched rapidly, making the lifecycle of new products ever shorter. Thus, it is important that companies understand consumers' needs and consider expert opinion when analyzing the development of a new technology. However, no studies have combined these two perspectives with regard to the development of a new product. Therefore, this research combined conjoint analysis, scenario analysis, and the Delphi method with the innovative diffusion model to analyze the development of Taiwan's TV market over the next 10 years. The results show that the outlook for demand for light-emitting diode (LED) TVs in Taiwan is very optimistic; sales of LED TVs will surpass sales of liquid crystal display TVs in 2015 in the optimistic scenario and in 2017 in the most likely scenario. 相似文献
