TL;DR: This paper systematically studies the most important mathematical theories used for modeling the network selection problem in the literature and compares the schemes of various mathematical theories and discusses the ways to benefit from combining multiple of them together.
Abstract: In heterogeneous wireless networks, an important task for mobile terminals is to select the best network for various communications at any time anywhere, usually called network selection. In recent years, this topic has been widely studied by using various mathematical theories. The employed theory decides the objective of optimization, complexity and performance, so it is a must to understand the potential mathematical theories and choose the appropriate one for obtaining the best result. Therefore, this paper systematically studies the most important mathematical theories used for modeling the network selection problem in the literature. With a carefully designed unified scenario, we compare the schemes of various mathematical theories and discuss the ways to benefit from combining multiple of them together. Furthermore, an integrated scheme using multiple attribute decision making as the core of the selection procedure is proposed.

TL;DR: This work develops an educational gaming system based on situated learning theory, and applies innovative augmented reality interactive technology to a library's learning environment through the proposed game-based augmented reality library instruction system (GARLIS).
Abstract: Due to limited budgets and manpower, most elementary schools in Taiwan do not plan or provide library instruction for students. Although students can use libraries, they typically lack the knowledge needed to use library resources effectively. Consequently, students have difficulty finding the books they need and can easily become overwhelmed by the massive amount of information in libraries. Computer-assisted instruction for teaching basic library skills to large numbers of students is an appealing method. Particularly, game-based learning has garnered considerable attention in education research. Many researchers and scholars believe that integrating teaching and games enhances student learning performance and motivation. This work develops an educational gaming system based on situated learning theory, and applies innovative augmented reality interactive technology to a library's learning environment. Student library knowledge can be enhanced via the proposed game-based augmented reality library instruction system (GARLIS). Experimental results demonstrate that student learning performance is improved significantly by using the proposed GARLIS. Moreover, this work demonstrates that using the proposed GARLIS for library instruction results in the same learning performance as conventional librarian instruction. The proposed library instruction system overcomes shortcomings of personal teaching skills of librarians that may adversely affect student learning performance by conveying the same learning content to all students. Additionally, the proposed system results in better learning performance for learners with the field-dependent cognitive style than learners with the field-independent cognitive style. Further, the proposed system provides more benefits in terms of library skills training than conventional librarian instruction.

TL;DR: The experimental results show that, when the learning path suggested by a hybrid decision tree is employed, the learners have a 90% probability of obtaining an above-average creativity score, which suggests that the employed data mining technique can be a good vehicle for providing adaptive learning that is related to creativity.
Abstract: Customizing a learning environment to optimize personal learning has recently become a popular trend in e-learning. Because creativity has become an essential skill in the current e-learning epoch, this study aims to develop a personalized creativity learning system (PCLS) that is based on the data mining technique of decision trees to provide personalized learning paths for optimizing the performance of creativity. The PCLS includes a series of creativity tasks as well as a questionnaire regarding several key variables. Ninety-two college students were included in this study to examine the effectiveness of the PCLS. The experimental results show that, when the learning path suggested by a hybrid decision tree is employed, the learners have a 90% probability of obtaining an above-average creativity score, which suggests that the employed data mining technique can be a good vehicle for providing adaptive learning that is related to creativity. Moreover, the findings in this study shed light on what components should be accounted for when designing a personalized creativity learning system as well as how to integrate personalized learning and game-based learning into a creative learning program to maximize learner motivation and learning effects.

TL;DR: In this article, the authors examined the drivers and performance outcomes of two patterns of internet use supporting export marketing: the internet as an alternative to a physical presence and the Internet as a sales channel.
Abstract: Purpose – While the internet enjoys increasing interest regarding its potential to extend the global reach of firms, especially small and medium‐sized firms (SMEs), little work has been done on the viability of the internet as a new and effective path to internationalization. Specifically, it is unclear how the internet can successfully support export marketing. The purpose of this paper is to examine the drivers and performance outcomes of two patterns of internet use supporting export marketing: the internet as an alternative to a physical presence and the internet as a sales channel.Design/methodology/approach – Data were collected from 115UK‐based SMEs involved in “active online internationalization”. Relationships are examined in a “soft‐modeling” partial least squares (PLS) analysis.Findings – The findings suggest that online channel support positively enhances export performance for SMEs. Yet, the use of the internet as an alternative to a physical market presence does not lead to higher export per...

TL;DR: The research illustrates that group eWOM's influence on brand community member's attitude toward the negative brand information is affected by member's level of brand community identification and brand involvement.
Abstract: Purpose – Brand communities now play a significant role in building brand loyalty. Past researches focus on how brand community facilitates brand loyalty under normal market situations. Yet, limited research examines consumer responses to negative events within the brand community context. Drawing from social identity theory and the theory of involvement, the present study aims to reveal the role that group eWOM plays in influencing brand community members’ evaluation on negative brand decisions.Design/methodology/approach – By using an experimental study, the current research adopts far brand extension as the empirical testing ground.Findings – This research illustrates that group eWOM's influence on brand community member's attitude toward the negative brand information is affected by member's level of brand community identification and brand involvement. When the group eWOM opposes far extension, high brand community identified members are driven by social creativity to resist negative impacts to the b...
TL;DR: HBV treatment guidelines should include the risk stratification of HCC to individualize the management of HBV carriers with different levels of H CC risk, and ample evidence indicates that HBsAg level can complement HBV‐DNA level in predicting HCC development, especially in HBV carrier with low viral load.
Abstract: Hepatitis B virus (HBV) infection is the major cause of chronic hepatitis, cirrhosis, and hepatocellular carcinoma (HCC) worldwide, especially in the Asia-Pacific region. Several hepatitis B viral factors predictive of clinical outcomes in HBV carriers have been identified. The Risk Evaluation of Viral Load Elevation and Associated Liver Disease/Cancer-HBV (REVEAL-HBV) study from Taiwan illustrated the strong association between HBV-DNA level at study entry and risk of HCC over time. In this community-based cohort study, male gender, older age, high serum alanine aminotransferase level, positive hepatitis B e antigen, higher HBV-DNA level, HBV genotype C infection, and core promoter mutation are independently associated with a higher risk of HCC. Another large hospital-based Elucidation of Risk Factors for Disease Control or Advancement in Taiwanese Hepatitis B Carriers cohort of Taiwanese patients further validated the findings of REVEAL-HBV. The risk of HCC started to increase when HBV-DNA level was higher than 2000 IU/mL. Both HBV-DNA and HBsAg levels were shown to be associated with HCC development. While HBV-DNA level had better predictive accuracy than HBsAg level, when investigating the overall cohort in patients with HBV-DNA level < 2000 IU/mL, HBsAg level ≥ 1000 IU/mL was identified as a new independent risk factor for HCC. With the results from REVEAL-HBV, a risk calculation for predicting HCC in non-cirrhotic patients has been developed and validated by independent cohorts (Risk Estimation for Hepatocellular Carcinoma in Chronic Hepatitis B).Taken together, ample evidence indicates that HBsAg level can complement HBV-DNA level in predicting HCC development, especially in HBV carriers with low viral load. In conclusion, HBV treatment guidelines should include the risk stratification of HCC to individualize the management of HBV carriers with different levels of HCC risk.
TL;DR: The authors identified important cognitive processes associated with processing narrative ads (comprehending narratives and generating mental imagery of depictions in the narratives) and related subjective experiences (perceptual/conceptual fluency, comprehension, and imagery fluency).
Abstract: This article identifies important cognitive processes associated with processing narrative ads (comprehending narratives and generating mental imagery of depictions in the narratives) and related subjective experiences (perceptual/conceptual fluency, comprehension, and imagery fluency). In line with the idea that perceptual/conceptual fluency facilitates comprehension fluency and further improves imagery fluency, this study presents a model in which factors influence imagery fluency either indirectly through influences on perceptual/conceptual and comprehension fluency or directly. Findings from two experiments support the model; picture type (narrative versus product picture) and narrative type (highly versus less accessible) indirectly alter imagery fluency through their influence on comprehension fluency, whereas individual characteristics (experiential versus rational processing orientation) directly alter it, which further affects ad and brand attitudes.

TL;DR: In this article, the authors investigated the effect of a firm's position in a supply chain in its industry on the attitude of the firm toward green strategies through empirical data analysis, and found that the internal and external driving forces of firms in promoting green practices are related to the types of uncertainties the firms encounter in the supply chain.
Abstract: – The aim of this study is to understand the effect of a firm's position in a supply chain in its industry on the attitude of the firm toward green strategies through empirical data analysis. This study aims to answer the following research questions: Do the environmental uncertainties a firm faces differ with the firm's position in the supply chain when going green?, Would the motivation of a firm for going green vary with uncertainties it faces in the supply chain? and Would green-related practices a firm accepts or executes vary with the firm's position in the supply chain? , – The case study method was utilized in this study. The main objects are firms in the high-tech industry of Taiwan, and 12 firms were selected for in-depth investigation. The unit of analysis was a firm. Face-to-face in-depth interviews, approximately 90-105 minutes for each, were conducted with each of the 12 cases. The respondents were middle- to high-level managers. The interviews were recorded and transcribed. Additionally, second-hand information was acquired regarding each case through channels such as firm web sites, documents, and media reports. These integrated data were later utilized in the single-case and cross-case analysis stages. , – In this study, firms of Taiwan's high-tech industry are divided into the upstream (raw material supplier), midstream (original design manufacturers/original equipment manufacturer), and downstream (brand company) categories. It is first found the uncertainties a firm encounters when implementing green practices are related to its position in the supply chain. The closer a firm is to the upstream of the supply chain, the higher the competitive uncertainty. In contrast, the closer a firm is to the downstream, the higher the demand uncertainty. Furthermore, the internal and external driving forces of firms in promoting green practices are related to the types of uncertainties the firms encounter in the supply chain. A firm's internal driving force is positively associated with the demand uncertainty it faces, however, negatively with the competition and supply uncertainties. On the other hand, a firm's external driving force is positively associated with the competition and supply uncertainties it faces, however, negatively with the demand uncertainties. Additionally, the association between firm willingness to promote green practices and its position in the supply chain is explored. It is found that, for firms located in the downstream of supply chain, it emphasizes more on the practices of green design, purchase, and internal environmental management. If a firm is located in the midstream of supply chain, it will focus more on the practice of green manufacturing and logistics. , – This study has expanded the discussion of green supply chain management. It establishes the relationship between the uncertainties and the major driving forces of firms for implementing green practices. This approach is rare in previous literature. Furthermore, past literature has suggested that a specific relationship exists between driving factors and firm practices. The author believes that such a relationship must be based on the position of firms in the supply chain; thus, the author has identified the relationship between supply chain position and green practices.
TL;DR: The authors examined the informational content of options trading on acquirer announcement returns and showed that implied volatility spread predicts positively on the cumulative abnormal return (CAR), and implied volatility skew predicts negatively on the CAR.
Abstract: This study examines the informational content of options trading on acquirer announcement returns We show that implied volatility spread predicts positively on the cumulative abnormal return (CAR), and implied volatility skew predicts negatively on the CAR The predictability is much stronger around actual merger and acquisition (M&A) announcement days, compared with pseudo-event days The prediction is weaker if pre-M&A stock price has incorporated part of the information, but stronger if acquirer’s options trading is more liquid Finally, we find that higher relative trading volume of options to stock predicts higher absolute CARs The relation also exists among the target firms
TL;DR: In this paper, the authors incorporate the perspectives of affective events theory into their research framework to clarify the mechanisms and boundary conditions of the customer negative event-service sabotage relationship in the context of face-to-face service.
Abstract: In the service industries, customer negative events towards a service provider, such as unreasonable demands or low-quality interpersonal treatment, might trigger service sabotage behaviours by the employee in response. Mitigating the problems associated with customer negative events is therefore an important issue for both practitioners and researchers. In the present study, we incorporate the perspectives of affective events theory into our research framework to clarify the mechanisms and boundary conditions of the customer negative event–service sabotage relationship in the context of face-to-face service. Specifically, we theorize and examine whether customer negative events lead to employee service sabotage through emotional reactions of the service worker (i.e. state hostility) and whether their personality traits (i.e. extraversion and neuroticism) and the work unit context (i.e. group affective tone) moderate this process. The sample was composed of 195 hairstylists and 61 managers from 6...
TL;DR: This paper provides a counterexample to the main theorem of Leshno and Levy related to almost second-degree stochastic dominance and shows that the newly defined almostSecond-degree Stochastic dominance is the necessary and sufficient condition to rank distributions for all decision makers excluding the pathological concave preferences.
Abstract: Leshno and Levy [Leshno M, Levy H (2002) Preferred by “all” and preferred by “most” decision makers: Almost stochastic dominance. Management Sci. 48(8):1074–1085] established almost stochastic dominance to reveal preferences for most rather than all decision makers with an increasing and concave utility function. In this paper, we first provide a counterexample to the main theorem of Leshno and Levy related to almost second-degree stochastic dominance. We then redefine this dominance condition and show that the newly defined almost second-degree stochastic dominance is the necessary and sufficient condition to rank distributions for all decision makers excluding the pathological concave preferences. We further extend our results to almost higher-degree stochastic dominance. This paper was accepted by Peter Wakker, decision analysis.
TL;DR: In this article, the authors used multilevel modeling to analyze data from 3,652 grade 1-9 teachers in 289 schools in Taiwan and found both teacher-level and school-level factors contributing to the integration of ICT in the teaching process.
Abstract: Technology integration is influenced by many factors related to the teacher and the school environment. While many studies have examined factors that influence teachers’ use of Information and Communication Technology (ICT) at the teacher level, a growing number of studies have suggested that it is beneficial to examine those factors using multilevel modeling. Multilevel analysis can separate the impact of teachers from the school environment and provide insight into the influence of those factors at each level. This study uses multilevel modeling to analyze data from 3,652 grade 1–9 teachers in 289 schools in Taiwan. The results of this multilevel analysis found both teacher-level and school-level factors contributing to the integration of ICT in the teaching process. Among teacher level factors, teachers’ beliefs and hours of training in the previous year predicted ICT integration proficiency well. Among school level factors, training hours and teachers’ perceived school support are the most important factors that impact ICT integration. School support is not only a significant factor at the school level but also a strong predictor at the teacher level. In addition, important school level variables included access to Internet connectivity, availability of projectors, and stability of computers. These results highlight the importance of individual teachers and the role schools play in ICT integration.

TL;DR: This study highlights the important role of NADPH oxidase in mediating oxidative stress in neurons and microglial cells and has unveiled the role of IFNγ in stimulating the MAPK/ERK1/2 signaling pathway for activation of NAD PH oxidase through the p-ERK-dependent pathway.
Abstract: Background: The bark of magnolia has been used in Oriental medicine to treat a variety of remedies, including some neurological disorders. Magnolol (Mag) and honokiol (Hon) are isomers of polyphenolic compounds from the bark of Magnolia officinalis, and have been identified as major active components exhibiting anti-oxidative, antiinflammatory, and neuroprotective effects. In this study, we investigate the ability of these isomers to suppress oxidative stress in neurons stimulated by the ionotropic glutamate receptor agonist N-methyl-D-aspartate (NMDA) and oxidative and inflammatory responses in microglial cells activated by interferon-γ (IFNγ) and lipopolysaccharide (LPS). We also attempt to elucidate the mechanism and signaling pathways involved in cytokine-induced production of reactive oxygen species (ROS) in microglial cells. Methods: Dihydroethidium (DHE) was used to assay superoxide production in neurons, while CM-H2DCF-DA was used to test for ROS production in murine (BV-2) and rat (HAPI) immortalized microglial cells. NADPH oxidase inhibitors (for example, diphenyleneiodonium (DPI), AEBSF, and apocynin) and immunocytochemistry targeting p47phox and gp91phox were used to assess the involvement of NADPH oxidase. Western blotting was used to assess iNOS and ERK1/2 expression, and the Griess reaction protocol was employed to determine nitric oxide (NO) concentration. Results: Exposure of Hon and Mag (1–10 μM) to neurons for 24 h did not alter neuronal viability, but both compounds (10 μM) inhibited NMDA-stimulated superoxide production, a pathway known to involve NADPH oxidase. In microglial cells, Hon and Mag inhibited IFNγ±LPS-induced iNOS expression, NO, and ROS production. Studies with inhibitors and immunocytochemical assay further demonstrated the important role of IFNγ activating the NADPH oxidase through the p-ERK-dependent pathway. Hon and, to a lesser extent, Mag inhibited IFNγ-induced p-ERK1/2 and its downstream pathway for ROS and NO production. Conclusion: This study highlights the important role of NADPH oxidase in mediating oxidative stress in neurons and microglial cells and has unveiled the role of IFNγ in stimulating the MAPK/ERK1/2 signaling pathway for activation of NADPH oxidase in microglial cells. Hon and Mag offer anti-oxidative or anti-inflammatory effects, at least in part, through suppressing IFNγ-induced p-ERK1/2 and its downstream pathway.
TL;DR: Based on first principles density functional calculations of the intrinsic anomalous and spin Hall conductivities, the authors predicts that the charge Hall current in Co-based full Heusler compounds Co2XZ (X = Cr and Mn; Z = Al, Si, Ga, Ge, In and Sn), except Co2CrGa, would be almost fully spin polarized.
Abstract: Based on first principles density functional calculations of the intrinsic anomalous and spin Hall conductivities, we predict that the charge Hall current in Co-based full Heusler compounds Co2XZ (X = Cr and Mn; Z = Al, Si, Ga, Ge, In and Sn), except Co2CrGa, would be almost fully spin polarized, even though Co2MnAl, Co2MnGa, Co2MnIn and Co2MnSn do not have a half-metallic band structure. Furthermore, the ratio of the associated spin current to the charge Hall current is slightly larger than 1.0. This suggests that these Co-based Heusler compounds, especially Co2MnAl, Co2MnGa and Co2MnIn which are found to have large anomalous and spin Hall conductivities, might be called anomalous Hall half-metals and could have valuable applications in spintronics such as spin valves as well as magnetoresistive and spin-torque-driven nanodevices. These interesting findings are discussed in terms of the calculated electronic band structures, magnetic moments and also anomalous and spin Hall conductivities as a function of the Fermi level.
TL;DR: In this paper, the authors attempted to validate a TPCK efficacy survey by implementing it on an Asian group of 550 preservice teachers from China, Hong Kong, Singapore and Taiwan.
Abstract: The Technological Pedagogical Content Knowledge (TPCK) framework has been adopted by many educational technologists and teacher educators for the research and development of knowledge about the pedagogical uses of Information and Communication Technologies (ICT) in classrooms. While the framework is potentially very important, efforts to survey teachers' TPCK efficacy has yet to identify all seven factors postulated by the framework. This study attempted to validate a TPCK efficacy survey by implementing it on an Asian group of 550 preservice teachers from China, Hong Kong, Singapore and Taiwan. The seven factors underlying the TPCK framework were identified which suggested the research instrument to be valid and reliable. The structural equation model proposed based on the TPCK framework supported eight out of 12 hypotheses about the relationships between TPCK constructs. The results indicate that the positive effects of the basic knowledge factors of CK, PK, and TK were indirect, occurring through the second layer of knowledge factors (TPK, TCK, and PCK). Implications for preservice teacher professional developments are discussed.
TL;DR: In this article, a vector error correction model (VECM) is proposed for mortality forecasts and mortality correlations among different countries under a VECM model are then derived, with payoffs based on a combined weighted mortality index.
Abstract: To deal with multi-country longevity risk, this article investigates the long-run equilibrium of mortality rates and introduces mortality correlations across countries as a means for pricing a multi-country longevity bond. The examination of the long-run equilibrium of the mortality rate relies on co-integration analysis, and a vector error correction model (VECM) is proposed for mortality forecasts. Mortality correlations among different countries under a VECM model are then derived. We take into account the mortality correlations across countries and utilize the multivariate Wang transform to derive the valuation formula for pricing the longevity bonds, with payoffs based on a combined weighted mortality index. This study illustrates the pattern of mortality correlations for men and women in the US and the UK, according to the Human Mortality Database. Our results show that mortality correlations across countries have a significant impact on pricing longevity bonds.
TL;DR: Li et al. as discussed by the authors investigated the differential relationships between abusive supervision and two emotional labor strategies used by subordinates (surface acting and deep acting) and examined whether subordinates' openness personality moderated the above relationships.
Abstract: We investigated the differential relationships between abusive supervision and two emotional labor strategies used by subordinates (surface acting and deep acting). Furthermore, we examined whether subordinates’ openness personality moderated the above relationships. Using the questionnaire survey method, we collected data from 210 employees in China. The results of hierarchical regression showed that abusive supervision related positively to surface acting (regulating facial expression) but negatively to deep acting (regulating inner feeling). Openness personality moderated the relationships between abusive supervision and the two emotional labor strategies, such that the relationships were stronger for employees with lower openness. Findings of our study contribute to the literature on workplace emotions and negative leadership.

TL;DR: In this article, the authors developed a scale-invariant Schumpeterian growth model with endogenous fertility and human capital accumulation and derived comparative statics of the equilibrium growth rates with respect to structural parameters.
Abstract: This study develops a scale-invariant Schumpeterian growth model with endogenous fertility and human capital accumulation. The model features two engines of long-run economic growth: R&D-based innovation and human capital accumulation. One novelty of this study is endogenous fertility, which negatively affects the growth rate of human capital. Given this growth-theoretic framework, we characterize the dynamics of the model and derive comparative statics of the equilibrium growth rates with respect to structural parameters. As for policy implications, we analyze how patent policy affects economic growth through technological progress, human capital accumulation, and endogenous fertility. In summary, we find that strengthening patent protection has (a) a positive effect on technological progress, (b) a negative effect on human capital accumulation through a higher rate of fertility, and (c) an ambiguous overall effect on economic growth.
