In recent years, governments around the world are actively promoting the Open Government Data (OGD) to facilitate reusing open data and developing information applications. Currently, there are more than 35,000 data sets available on the Taiwan OGD website. However, the existing Taiwan OGD website only provides keyword queries and lacks a friendly query interface. This study aims to address these issues by defining a DBpedia cloud computing framework (DCCF) for integrating DBpedia with Semantic Web technologies into Spark cluster cloud computing environment.

The proposed DCCF is used to develop a Taiwan OGD recommendation platform (TOGDRP) that provides a friendly query interface to automatically filter out the relevant data sets and visualize relationships between these data sets.

To demonstrate the feasibility of TOGDRP, the experimental results illustrate the efficiency of the different cloud computing models, including Hadoop YARN cluster model, Spark standalone cluster model and Spark YARN cluster model.

The novel solution proposed in this study is a hybrid approach for integrating Semantic Web technologies into Hadoop and Spark cloud computing environment to provide OGD data sets recommendation.

The purpose of this paper is to study the influence of silver on the high‐temperature oxidation behaviour of the Sn‐8.5Zn‐xAg‐0.01Al‐0.1Ga (x=0, 0.1, 0.3 and 0.5) solder alloys.

The weight gains of the studied solders are measured using thermal gravimetric analyzers (TGA) at temperatures of 250, 300, 350 and 400°C. The weight gains measured are used to compare the oxidation behaviour of the studied solders. The surfaces of the solders are also analyzed with Auger emission spectroscopy (AES) depth profiling and thin‐film X‐ray diffractometry (thin‐film XRD) to identify the elements present on the surface of the studied solders.

The TGA results show that the weight gains decrease with increasing silver content in the studied solders. It meant that increasing silver content could help improve the high‐temperature oxidation behaviour of the studied solder. AES and thin‐film XRD confirm that the formed oxide layers on the surface of the studied solder are Zn‐based oxide layers.

The findings of this paper will help provide an understanding of the effects of silver on Sn‐8.5Zn‐xAg‐0.01Al‐0.1Ga solder.

This paper aims to compare the reflow and Zn diffusion behaviors in Sn-Zn and Sn-8.5Zn-0.5Ag-0.01Al-0.1Ga (5E) solders during soldering on a Ni/Cu substrate under infrared (IR) reflow. The study proposes a model on the effect of various elements particularly Zn diffusion behavior in the solders on the formation of intermetallic compounds (IMCs).

The melting activities of two solders near their melting points on copper substrates are visualized in an IR reflow furnace. Reflowed solder joints were analyzed using scanning electron microscope and energy dispersive X-ray spectroscopy.

Reflow behaviors of the solders are similar. During melting, solder balls are first merged into each other and then reflow on the substrate from top to bottom. Both solders show a reduced amount of Zn in the solder. Theoretical calculations demonstrate a higher Zn diffusion in the 5E solder; however, the amount of Zn actually observed at the solder/substrate interface is lower than Sn-9Zn solder due to the formation of ZnAg3 in the solder. A thinner IMC layer is formed at the interface in the 5E solder than the Sn-Zn solder.

The present work compares the 5E solder only with Sn-Zn solder. Additional research work may be required to compare 5E solder with other solders like Sn-Ag, SnAgCu, etc. to further establish its practical applications.

The study ascertains the advantages of 5E solder over Sn-Zn solder for all practical applications.

The significance of this paper is the understanding of the relation between reflow behavior of solders and reactivity of different elements in the solder alloys and substrate to form various IMCs and their influence on the formation of IMC layer at solder/substrate interface. Emphasis is provided for the diffusion behavior of Zn during reflow and respective reaction mechanisms.

This study aims to investigate the fabrication of hydrogen gas sensor based on metal–oxide–semiconductor (MOS) microstructure. The palladium nanoparticles (PdNPs) as gate metal have been deposited on the oxide film using spin coating.

The PdNPs and the surface of oxide film were analyzed using Transmission electron microscopy. The capacitance-voltage (C-V) curves for the MOS sensor in 1, 2 and 4 per cent hydrogen concentration and in 100 KHz frequency at the room temperature were reported.

The response times for 1, 2 and 4 per cent hydrogen concentration were 2.5 s, 1.5 s and 1 s, respectively. The responses (R per cent) of MOS sensor to 1, 2 and 4 per cent hydrogen concentration were 42.8, 47.3 and 52.6 per cent, respectively.

The experimental results demonstrate that the MOS hydrogen gas sensor based on the PdNPs gate, shows the fast response and recovery compared to other hydrogen gas sensors based on the Pd.

The purpose of this paper is to analyze how professional cultures in schools and school systems could improve the well-being of students, with a particular emphasis on teacher-health partnerships, which would not naturally occur without a specific intentional intervention. Implemented with a whole-school approach, the Health Promoting School (HPS) is one of the most effective intentional interventions to achieve improvements in both the health and educational outcomes of students through the engagement of key stakeholders in education and health to create a healthy physical/psycho-social environment. This paper emphasizes collaboration and the building of professional cultures in schools that share collective responsibility for the whole student.

Student outcomes in schools should include both academic and health and well-being outcomes that promote positive pathways throughout adulthood. This paper connects HPS research with policy analysis drawing on Hong Kong’s unique context as being at the top of the PISA rankings and striving toward a positive health culture and well-being in its schools.

Evidence has been gathered extensively about what schools actually do in health promotion using the HPS framework. The HPS framework has served to assist schools and authorities to concentrate on the gaps and affirm best practices. This paper also reports how teachers have created a professional and collegial community with health partners to address outbreaks of infectious diseases in schools and obesity in students.

The concept of HPS can serve as an ecological model to promote the positive health and well-being of students, fostering their personal growth and development, and as an alternate model for school improvement.

This paper has highlighted that structured school health programs such as HPS could have positive effects on educational outcomes, while also changing professional cultures and communities in schools with an emphasis on students’ physical health, emotional health, social health, or spiritual health. The Assessment Program for Affective and Social Outcomes is used as a tool by schools in Hong Kong, reflecting the affective and social developments of the students in the school under review as a whole, and how they relate to the school. It resembles the core areas of action competencies, and school social environment; the two key areas of HPS.

Hong Kong is often analyzed from an educational rankings perspective. However, it offers broader lessons on educational change, as it has in recent years emphasized dual goals in student outcomes and professional communities – the importance of whole student health and well-being as a both a precursor and key component to the educational outcomes schools seek. Globally, very few schools are able to implement HPS in its entirety. Continuing development of HPS in Hong Kong would add value to international literature in terms of which types of data would influence adoption of HPS in which types of school and policy contexts.

The focus in this study is a model that predicts continuance intention of online multi-player games. In this integrated model, the social cognitive theory (SCT) lays out the foundation of two types of pre-use (pre-play) expectations, the flow theory captures the affective feeling with the game as a moderator for the effect from the two pre-use expectations, and subjective norm together with its associated antecedents cover a wide spectrum of social influences.

A questionnaire was designed and pre-tested before distributing to target respondents. The reliability and validity of the instrument both met the commonly accepted guidelines. The integrated model was assessed first by examining its measurement model and then the structural model.

The integration of cognitive, affective and social influence in this model explains a larger amount of variance compared to the competing models and existing studies.

Unlike a popular trend that studies predictors of online games from either cognitive or affect angle, the work looks at both together to study how their joint effect is related to continuance intention. This marks an important improvement as cognitive expectations derived from SCT captures the pre-use experience that may be influenced or swayed by sources including those that are inflated or incorrect. By studying flow as a moderator in conjunction with other sources of influence, the authors are able to further the understanding of how the pre-use expectations may be shaped by one's own experience.

Organizational researchers studying well-being – as well as organizations themselves – often place much of the burden on employees to manage and preserve their own well-being. Missing from this discussion is how – from a human resources management (HRM) perspective – organizations and managers can directly and positively shape the well-being of their employees. The authors use this review to paint a picture of what organizations could be like if they valued people holistically and embraced the full experience of employees’ lives to promote well-being at work. In so doing, the authors tackle five challenges that managers may have to help their employees navigate, but to date have received more limited empirical and theoretical attention from an HRM perspective: (1) recovery at work; (2) women’s health; (3) concealable stigmas; (4) caregiving; and (5) coping with socio-environmental jolts. In each section, the authors highlight how past research has treated managerial or organizational support on these topics, and pave the way for where research needs to advance from an HRM perspective. The authors conclude with ideas for tackling these issues methodologically and analytically, highlighting ways to recruit and support more vulnerable samples that are encapsulated within these topics, as well as analytic approaches to study employee experiences more holistically. In sum, this review represents a call for organizations to now – more than ever – build thriving organizations.

Artificial intelligence (AI) is shaping the future of the marketing world. This study is the first to examine the effect of AI marketing efforts, brand experience (BE) and brand preference (BP) in light of the stimulus-organism-response (SOR) model.

The data collected from 398 participants by the questionnaire method were analyzed by SEM (structural equation modeling) using Smart PLS 4.0 and IBM SPSS 26 programs.

We find that four SOR elements of AI marketing efforts (information, interactivity, accessibility and personalization) positively impact bank customer BE, BP and repurchase intention (RPI). Further, we find that BE plays a mediator role in the relationship between AI marketing efforts, RPI and BP.

The findings of the study have significant implications for the bank marketing literature and the banking industry, given the limited evidence to date regarding AI marketing efforts and bank–customer relationships. Moreover, the study makes important contributions to the AI marketing and brand literature and helps banks increase customer experience with artificial intelligence activities and create long-term relationships with customers.

The purpose of the paper is to investigate the price interrelationship between the Taiwanese and US financial markets.

The trivariate GJR‐GARCH (1,1) model and event study were employed to investigate volatility asymmetry and overreaction phenomenon, respectively.

The empirical results show that return volatility reveals the asymmetric phenomenon, and the holding period returns on US index futures from the opening of the US index futures electronic trading to the opening of the Taiwanese stock market are an important reference for investors in the Taiwanese stock market. Additionally, the paper presents an overreaction of the Taiwan Stock Exchange Capitalization Weighted Stock Index to a drastic price rise of E‐min NASDAQ 100 Index futures at the opening of the Taiwanese stock market.

This paper deletes the observations arising from the different national holidays of the USA and Taiwan, to have the same number of observations in both markets, which might contaminate the empirical results.

Investors in the Taiwanese stock market tend to pay more attention to the fluctuations in the share prices of high‐technological companies in the USA.

Most of the previous studies regarding price transmission between the Taiwanese and US stock markets focused mainly on the Taiwanese market reactions to the overnight returns of the US market. This paper enlarges the current field by examining the lead‐lag relationship, the volatility asymmetry, and the overreaction phenomenon between the Taiwanese and US financial markets according to the most updated US stock index information.

Being different from others can be stressful, and this may be especially salient for newcomers during organizational socialization when they may be expected to fit in. Thus, drawing on conservation of resources theory, the authors examine the effects of newcomers' individual differentiation on their subsequent emotional exhaustion.

The authors test a multiple mediation model with data from 161 UK graduates collected at three times using structural equation modeling.

The results largely support the hypotheses, identifying individual differentiation as a motivational resource associated with the proactive behavior of changing work procedures. In turn, changing work procedures links with the personal resource of positive affect, which facilitates the relational resource of social acceptance and predicts lower emotional exhaustion. Individual differentiation predicts lower social acceptance also, but not via monitoring as anticipated.

The results provide novel insights into the effects of individual differentiation on emotional exhaustion in the context of organizational socialization. The study highlights that, while newcomers high in individual differentiation face depletion of the relational resource of social acceptance, they can still adjust well and avoid emotional exhaustion through changing work procedures to foster positive affect.
