The senior high school students’ learning behavioral model of STEM in PBL

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.     

The impact of problem-based learning strategies on STEM knowledge integration and attitudes: an exploratory study among female Taiwanese senior high school students

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.     

Do Hispanic immigrants spend less on medical care? Implications of the Hispanic health paradox

ABSTRACT

The literature of the Hispanic heath paradox has found that in the U.S. Hispanic immigrants have better health than U.S. natives, even though they tend to have lower socioeconomic status. The main objective of the current study is to investigate whether Hispanic immigrants also use less medical care goods and services. Main contributions of the article include using a data set of older Americans from the Health and Retirement Study covering the period from 1992 to 2012 as well as using three new measures of health, rather than the more common use of morbidity or mortality. We estimate the impact of relevant factors including health, race, and immigrant status upon five different measures of healthcare usage. Even though Hispanic immigrants do have lower mean levels of most measures of healthcare usage, when controlling for other factors in our regressions we find some evidence of increased healthcare usage for Hispanic immigrants. Increased health care utilization may be one explanation for the Hispanic health paradox.     

A feasibility study of stateful automaton packet inspection for streaming application detection systems

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.     

Exploring location‐specific assets and exploiting firm‐specific advantages: an integrative perspective on foreign ownership decisions

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.

Combining conjoint analysis,scenario analysis,the Delphi method,and the innovation diffusion model to analyze the development of innovative products in Taiwan's TV market

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.     

A New Framework Integrating Environmental Effects into Technology Evaluation

This study aims to propose a framework considering both economic issues and environmental effects in technology evaluation in order to provide firms’ decision makers a useful reference in adopting technologies that will enable them to fulfill corporate social responsibilities and get competitive advantages at the same time. Recently, the demands for technology evaluation have increased with the flourishing development of technology licensing, technology transaction or joint venture on the one hand and with the pressing needs of environmental protection for human beings’ sustainable development on the other hand. Under such conditions, it thus goes without saying that firms’ decision makers are propelled to take into account both economic benefits and environmental effects in evaluating technologies by choosing low or nonpolluting technologies for manufacturing products. Although technology evaluation is not a new and emerging subject currently besetting scholars in the field of management, previous research on this topic has unwittingly left behind the pressing issue of environmental effects. Based on this observation, this study purports to develop a new framework for technology evaluation by taking both economic benefits and environmental perspectives into consideration. In it, we seek to demonstrate that our proposed framework will not only be a workable model but also can serve as a useful point of reference for technology appraisers and firms’ decision makers.     

The main paths of eTourism: trends of managing tourism through Internet

Drawing from the tourism and hospitality literature, this paper highlights the main research trajectories and themes in the context of eTourism. We use main path analysis to investigate the development trend of the synergistic relationship between innovative tourism applications and the new technologies. Further, the literature is classified into six groups through discovering the coherence structure in a citation network. The analyses show that research on websites, blogs, and social media on tourism is experiencing accelerated growth, which hints that there is a pendulum shift whereby the information and negotiation power asymmetry between the supply and demand sides are moving from provider-centric to consumer-centric. This study also elucidates the associated market disintermediation phenomenon and long tail effects on the distribution of destinations.     

Images of the Virtuous Employee in China's Transitional Economy

We examine contemporary images of employee virtue and managers' perceptions of actual employee conduct in Wuhan, Beijing and Xi'an, drawing on document analysis and structured interviews with 112 respondents in ten case study companies. The image promulgation strategies of the one joint venture enterprise and the two private enterprises in our sample entailed active avowal of tradition linked employee virtue, drawing on a mixture of Communist and Confucian moral imagery. In contrast, most of the seven state-owned or predominantly state invested enterprises had abandoned or marginalized traditional Communist imagery, none promoted Confucian imagery, and two emphasized alternative images of one-sided servility toward the customer. We infer, from managers' accounts, that the abandonment of tradition linked images by the state-owned sector was a tacit acknowledgment of prior covenant violation, and that outside the state-owned sector, tradition linked moral propaganda contributed to moral atmosphere only when part of a consistent high-commitment HRM strategy. In drawing out implications for theory and further research, we note the different socio-political contexts of organizations in China and the West, discuss the relationship between bonds or covenants and psychological contracts, and compare tradition linked employee virtues with dimensions of organizational citizenship.     

Fuzzy Seasonal Time Series for Forecasting the Production Value of the Mechanical Industry in Taiwan

Based on the seasonal time series ARIMA(p,d,q)(P,D,Q)_s model (SARIMA) and fuzzy regression model, we combine the advantages of two methods to propose a procedure of fuzzy seasonal time series and apply this method to forecasting the production value of the mechanical industry in Taiwan. The intention of the article is to provide the enterprises, in this era of diversified management, with a fresh method to conduct short-term prediction for the future in the hope that these enterprises can perform more accurate planning. This method includes interval models with interval parameters and provides the possibility distribution of future value. From the results of practical application to the mechanical industry, it can be shown that this method makes good forecasts. Further, this method makes it possible for decision makers to forecast the possible situations based on fewer observations than the SARIMA model and has the basis of pre-procedure for fuzzy time series.
