Understanding Chinese Hospitality Management Master\u27s Students\u27 Satisfaction With Their Education

The purpose of the present research was to understand Chinese students\u27 expectations and experiences with their Master\u27s education in hospitality-related programs in the U.S. Three groups of persons could potentially benefit from the results of the study: university administrators, professors, and graduate students of hospitality management programs (both current and future students). In-depth interviews were conducted with twenty-one Chinese Master\u27s students in a Hospitality and Tourism Management (HTM) program at a Midwest research university. Content analysis was performed to identify themes regarding students\u27 expectations, experiences and satisfaction with their graduate programs. When comparing Chinese hospitality management Master\u27s students\u27 expectations and actual experiences, the researcher found both similarities and differences. The participants mentioned actual experiences that were in line with their expectation. Some of the most representative aspects were as follows. The program was research-based and students could get systematic training in academic theories and research methodologies. Students had much interaction with professors and they felt free to exchange ideas with them. The professors were willing to help students and exchange ideas with them. The university also provided students with opportunities for career preparation, such as mock interviews and résumé development workshops. However, the researcher also found some differences between Chinese Master\u27s students\u27 actual experiences and their expectations prior to commencing the program. Some differences in the academic aspects were as follows. Students expected to receive knowledge that was updated and connected to the hospitality industry, some thought that what they actually learned was overly academic and not adequately applicable to the industry. The students also reported that the actual academic workload was much higher than expected and they were too busy with academic tasks to explore their personal interests. Participants expected to work with professors on real business projects while in reality students only worked with professors on course-related assignments. Students expected the career center to help them find jobs, instead, they felt the assistance they received was not adequate. Non-academically, students expected to make friends with students from other countries and experience the U.S. culture. However, they thought that in reality they were less motivated to participate in local activities and they ended up only making friends with Chinese students because of the large number of Chinese students in the program

Curvy surface conformal ultra-thin transfer printed Si optoelectronic penetrating microprobe arrays

Penetrating neural probe arrays are powerful bio-integrated devices for studying basic neuroscience and applied neurophysiology, underlying neurological disorders, and understanding and regulating animal and human behavior. This paper presents a penetrating microprobe array constructed in thin and flexible fashion, which can be seamlessly integrated with the soft curvy substances. The function of the microprobes is enabled by transfer printed ultra-thin Si optoelectronics. As a proof-of-concept device, microprobe array with Si photodetector arrays are demonstrated and their capability of mapping the photo intensity in space are illustrated. The design strategies of utilizing thin polyimide based microprobes and supporting substrate, and employing the heterogeneously integrated thin optoelectronics are keys to accomplish such a device. The experimental and theoretical investigations illustrate the materials, manufacturing, mechanical and optoelectronic aspects of the device. While this paper primarily focuses on the device platform development, the associated materials, manufacturing technologies, and device design strategy are applicable to more complex and multi-functionalities in penetrating probe array-based neural interfaces and can also find potential utilities in a wide range of bio-integrated systems

Biosensors for Rapid Detection of Avian Influenza

The scope of this chapter was to review the advancements made in the area of biosensors for rapid detection of avian influenza viruses (AIVs). It is intended to provide general background about biosensor technology and to discuss important aspects for developing biosensors, such as selection of the suitable biological recognition elements (anti-AIV bioreceptors) as well as their immobilization strategies. A major concern of this chapter is also to critically review the biosensors’ working principles and their applications in AIV detection. A table containing the types of biosensor, bioreceptors, target AIVs, methods, etc. is given in this chapter. A number of papers for the different types of biosensors give hints on the current trends in the field of biosensor research for its application on AIV detection. By discussing recent research and future trends based on many excellent publications and reviews, it is hoped to give the readers a comprehensive view on this fast-growing field

The Application of the Cognitive Radio in the Aviation Communication Spectrum Management

AbstractIt is concerned that the aviation communication system is interfered by the inner and outside interference. Because of the electromagnetic spectrum is limited, it must be controlled and managed in order to use in aviation communication. The cognitive radio (CR) can perceive the electromagnetic environment automatically, search the spectrum holes, and adjust the signal parameters of both sides by communication protocols and algorithms to best situation. This paper discusses the CR and the application in the spectrum management of aviation communications

Mathematical Modeling of Eddy-Current Loss for a New Induction Heating Device

A new induction heating device is presented in this paper. This device can convert mechanical energy into heat energy by utilizing eddy currents, which are induced by rotating permanent magnets. A mathematical model is established for estimating eddy-current loss of the device. The distribution of induced currents and the resultant magnetic field intensity are considered in the process of modeling the eddy-current loss and so is the mutual influence of the electric field between neighborhood pole projection areas. Particularly, the skin effect is considered by correcting the numerical integral domain of eddy current density, which has great effect on the calculating results. Based on specific examples, the effectiveness and correctness of proposed model are proved by finite element analysis. The results show that the mathematical model can provide important reference for design and structure optimization of the device

Magnetic poles enabled kirigami meta-structure for stable mechanical memory storage with high information density

Some bi or multi-stable Mechanical meta-structures have been implemented as mechanical memory devices which however are with limits such as complex structural forms, low information storage capability and/or fragile structural stability to maintain the stored information bits robustly under external interferences. To address these issues, we refer to the structural intelligence by constructing a simple 3D-printable multi-layered cylindrical kirigami module with gradient structural parameters and propose a mechanical memory device that can robustly store information bits exponentially larger than previous designs. We demonstrate the promising enhancement of information storage capability of our proposed mechanical memory device relies on two mechanisms 1 the deformation sequences of the kirigami module enabled by the gradient structural parameter, which brings the extra dimensional degree of freedom to break the traditional mechanical memory unit with only planar form and merits information bits with spatially combinatorical programmability, and 2 the combinatorics of the deformation independences among the cylindrical kiriagmi unit arrays in the constructed mechanical memory device. Particularly, we achieve both the structural stabilities and the desired structural robustness in the mechanical memory devices by additively introducing magnetic N-S poles in units, which can protect the stored information from interferences like mechanical crushing, impacting and or shaking
