Surface acoustic wave (SAW) sensors have attracted great attention worldwide for a variety of applications in measuring physical, chemical and biological parameters. However, stability has been one of the key issues which have limited their effective commercial applications. To fully understand this challenge of operation stability, this paper aims to systematically review mechanisms, stability issues and future challenges of SAW sensors for various applications.

This review paper starts with different types of SAWs, advantages and disadvantages of different types of SAW sensors and then the stability issues of SAW sensors. Subsequently, recent efforts made by researchers for improving working stability of SAW sensors are reviewed. Finally, it discusses the existing challenges and future prospects of SAW sensors in the rapidly growing Internet of Things-enabled application market.

A large number of scientific articles related to SAW technologies were found, and a number of opportunities for future researchers were identified. Over the past 20 years, SAW-related research has gained a growing interest of researchers. SAW sensors have attracted more and more researchers worldwide over the years, but the research topics of SAW sensor stability only own an extremely poor percentage in the total researc topics of SAWs or SAW sensors.

Although SAW sensors have been attracting researchers worldwide for decades, researchers mainly focused on the new materials and design strategies for SAW sensors to achieve good sensitivity and selectivity, and little work can be found on the stability issues of SAW sensors, which are so important for SAW sensor industries and one of the key factors to be mature products. Therefore, this paper systematically reviewed the SAW sensors from their fundamental mechanisms to stability issues and indicated their future challenges for various applications.

The research article looks at how well China is managing its tech skills resources in major industries.

The IBM Institute for Business Value in collaboration with Oxford Economics recently conducted a specific survey of more than 5,600 global business, government and education leaders on the topic of global workforce skills. More than 400 of the 5,600 executives surveyed were from China, representing 18 specific industries from across all major regions. The insights and opinions of these 400-plus Chinese executives inform this report about tech skills resources in China.

Seventy-one percent of corporate recruiters in China, say they cannot find applicants with sufficient practical experience, and 72 percent of the Chinese industry leaders surveyed report that gaps evidenced in the core skills of newly recruited employees is the single most significant business challenge they face.

The interviews were performed in 2016 and the data analyzed in 2017 and 2018.

Seventy-one percent of Chinese executives believe that individuals should bear significant personal responsibility in developing and maintaining work skills.

This is a large sample of executives in major Chinese corporations and some representatives of Chinese educational institutions. Their insights about China’s talent gaps and what it is doing on many fronts to modernize its talent resources should be of interest to players in all competitive economies.

Marketers may proactively give customers personalized notices regarding their progress toward certain rewards as a means to stimulate ongoing behaviors. This paper aims to investigate the effect on customer repatronage intention by framed messages concerning either goal-distance or consequences of an action and it also seeks to identify important variables moderating those responses.

Five between-subjects experiments examined how participants’ repatronage intentions, in response to the framing of goal-distance (Study 1a) and consequences of an action (Study 2a), varied as a function of their level of progress toward goal completion and also tested if the framing effects might be attenuated when relationship benefit was high rather than low (Studies 1b and 2b). They further adopted perceived reciprocity as an underlying mechanism for examining the interplay between these two kinds of framing in stimulating ongoing behavior (Study 3).

Although messages which emphasized what individuals need to spend more to attain a reward (versus how short they are from earning a reward) or loss following inaction (versus gain following action) were likely to erode intention, such effects were confined to individuals with a moderate level of progress. This intention-eroding effect was further attenuated by attractive reward. The persuasive advantages of short-from-the-end framing of goal-distance over more-to-the-end counterparts were found to be diminished when paired with a loss-framed message concerning consequences of an action. Furthermore, the observed effects on intention were mediated by perceived reciprocity.

The studies add to the current understanding of how the way in which information is presented might enhance loyalty or fail to do so.

Drawing on leader-member exchange theory and regulatory focus theory, the purpose of this study is to explore the effects of hotel employees’ regulatory foci on their voice behavior and the moderating role of leader-member exchange.

The questionnaire includes demographics, regulatory foci, leader-member exchange and voice behavior sections. The data was collected via a survey of 10 international tourist hotels in Taiwan and 479 valid questionnaires were completed. Confirmatory factor analysis and path analysis were used to test the composite reliability, discriminant validity and convergent validity. Multiple regression analysis was used to test the hypotheses.

The outcome of this study indicates that both promotion focus and prevention focus can benefit employees’ voice behavior; however, prevention-focused employees have more positive voice behavior than promotion-focused employees. In addition, the leader-member exchange can moderate the relationship between regulatory foci and voice behavior.

This is an empirical study in the hotel field to examine the moderating effects of leader-member exchange on the relationships between regulatory foci and voice behavior. This research is contributed toward human resource management literature in the hospitality and tourism domain. Practices for managers and suggestions for future research are discussed.

A British Airways flight crew arrives after a long flight from London to Chicago to find their hotel rooms are not ready for check-in. The front-desk agents tell them that the hotel is overbooked. The flight crew is asked to wait in the hotel lobby for more than one and a half hours while housekeepers prepare their rooms. Upon returning to London, the pilot complains to British Airways. What should the hotel have done differently to avoid complaints?

The consistency of stochastic frontier analysis (SFA) and data envelopment analysis (DEA) cost efficiency measures using a sample of 650 commercial and domestic banks in the United States is investigated based on cluster analysis while accounting for the yearly variation in banks.

Due to the importance of efficiency measures for policy and managerial decision-making, the cost efficiency measures of SFA and DEA estimators are examined according to four criteria: levels, rankings, stability over time and stability over clustering groups. In this paper, we present two clustering methods, Gap Statistic and Dindex, that involve SFA and DEA cost efficiency measures. The clustering approach creates homogeneous groups of banks offering a similar mix of efficiency levels. Hence, each evaluated bank knows the cluster to which it belongs. Furthermore, this paper provides nonparametric statistical tests of SFA and DEA cost efficiency measures estimated with and without a clustering approach.

The results suggest that the clustering approach plays a considerable role in the rankings of US banks. Furthermore, the average SFA and DEA cost efficiency measures over time of the homogeneous US banks are substantially higher than those of the heterogeneous US banks.

This research is the first to provide comparative efficiency measures needed for desirable policy conclusions of heterogeneous and homogeneous US banks.

The paper provides an integrated multi‐disciplinary and multi‐level research framework that organizes the body of knowledge, scattered in different literature and contexts, in a state‐of‐the‐art piece of the research into technology entrepreneurship capabilities, as well as to identify more specific research questions, model, testable hypothesis and related studies that build on and add value to previous research.

Man has been seeking an ideal existence for a very long time. In this existence, justice, love, and peace are no longer words, but actual experiences. How ever, with the American preemptive invasion and occupation of Afghanistan and Iraq and the subsequent prisoner abuse, such an existence seems to be farther and farther away from reality. The purpose of this work is to stop this dangerous trend by promoting justice, love, and peace through a change of the paradigm that is inconsistent with justice, love, and peace. The strong paradigm that created the strong nation like the U.S. and the strong man like George W. Bush have been the culprit, rather than the contributor, of the above three universal ideals. Thus, rather than justice, love, and peace, the strong paradigm resulted in in justice, hatred, and violence. In order to remove these three and related evils, what the world needs in the beginning of the third millenium is the weak paradigm. Through the acceptance of the latter paradigm, the golden mean or middle paradigm can be formulated, which is a synergy of the weak and the strong paradigm. In order to understand properly the meaning of these paradigms, however, some digression appears necessary.
