Thermopile infrared (IR) detectors are one of the most important IR devices. Considering that the surface area of conventional four-end-beam (FEB)-based thermopile devices cannot be effectively used and the performance of this type of devices is relatively low, this paper aims to present a double-end-beam (DEB)-based thermopile device with high duty cycle and performance. The paper aims to discuss these issues.

Numerical analysis was conducted to show the advantages of the DEB-based thermopile devices.

Structural size of the DEB-based thermopiles may be further scaled down and maintain relatively higher responsivity and detectivity when compared with the FEB-based thermopiles. The authors characterized the thermoelectric properties of the device proposed in this paper, which achieves a responsivity of 1,151.14 V/W, a detectivity of 4.15 × 108 cm Hz1/2/W and a response time of 14.46 ms sensor based on DEB structure.

The paper proposed a micro electro mechanical systems (MEMS) thermopile infrared sensor based on double-end-beam structure.

Deep excavation in soft clay often causes additional deformations to surroundings. Then, if deformations cannot be predicted reasonably, the adjacent buildings may be threatened by the deep excavation. Based on the good field observations from ten deep excavations in Hangzhou, this paper aims to thoroughly investigate the characteristics of wall deflections and ground settlements induced by deep excavations.

On the basis of good field observation of ten deep excavations, the performances of excavations, supported by contiguous pile in Hangzhou, were studied, and also compared with other case histories.

The maximum wall deflections (dhm) rang mostly from 0.7 to 1.2 per cent H_e, where He is the final excavation depth, larger than those in Taipei and Shanghai. The observed maximum ground settlement in the Hangzhou cases generally ranges from 0.2 to 0.8 per cent H_e. Then, the settlement influence zone extends to a distance of 2.0-4.0 H_e from the excavation. The relatively large movements and influence zones in Hangzhou may be attributed to low stability numbers, large excavation widths and the creep effect. The excavation width is justified to have a significant influence on the wall deflection. Therefore, to establish a semi-empirical formula for predicting the maximum wall deflection, it is necessary to include the factor of excavation width.

The relevant literature concentrated on the characteristics of deep excavations supported by the contiguous pile wall in Hangzhou soft clay can rarely be found. Based on the ten deep excavations with good field observation in Hangzhou, the characteristics of wall deflection and ground settlements were comprehensively studied for the first time, which can provide some theoretical support for similar projects.

The purpose of this paper is to investigate the relationship between e-buyers and e-sellers in the context of the Chinese culture. It examines the relationships among swift guanxi, trust, uncertainty, and repurchase intentions. This study probes the possible mediation effects caused by the process where consumers form their thoughts and actions.

This study developed a theoretical model to examine how swift guanxi, trust, and uncertainty influence repurchase intentions of online auction consumers. The mediation effects of trust and uncertainty were also examined. This study gathered 455 valid samples and analyzed data by applying a structural equation modeling.

The results confirm that swift guanxi has significant and positive effects on trust and repurchase intentions, but swift guanxi has a significant and negative effect on uncertainty. In addition, trust has a significant and positive effect on repurchase intentions. On the other hand, uncertainty has a significant and negative effect on repurchase intentions. Finally, both trust and uncertainty have partial mediation effects between swift guanxi and repurchase intention.

The findings extend the current state of knowledge about the relationships among swift guanxi, trust, uncertainty, and repurchase intentions, as well as reveal the psychological mechanism of the effects of trust and uncertainty on repurchase intentions.

The findings provide a deeper understanding of the effect of customers’ swift guanxi on repurchase intentions under different perspectives of the double-edged sword of trust and uncertainty in Yahoo! Online auction.

This study decomposes the constructs of swift guanxi, trust, and uncertainty into various dimensions and investigates the relationships between these dimensions and repurchase intentions. It has not been done in this way previously. The results contribute to the understanding of online auction customers’ behaviors.

Under the background of rapid urbanization, all kinds of urban water problems have gradually come into being: local flooding frequently happens, water environment is deteriorated, water-supply is in tension, etc. Meanwhile, with rapid development of higher education in China, campus area and scale are gradually expanding, but traditional campus construction has many drawbacks. In order to promote sponge campus planning and construction of universities in hilly areas and provide demonstration windows for sponge city construction, based on deficiencies of campus construction of Hunan City University in the aspect of water resource utilization, we used ArcGis spatial analysis method, simulation method and comparative analysis method on Storm Water Management Model (SWMM) to establish sponge campus construction indexes, content system and optimal design strategies with objectives of campus water safety, water environment and water resource utilization. Results indicate that: difference between sponge campus planning and traditional campus planning mainly lies in rainfall management. We combed the design process of sponge campus planning in hilly areas from the perspective of rainfall management, and simulated the process of sponge facilities controlling the rainfall in the campus via computer model to verify reasonability of sponge facility planning and select the optimal planning and construction plan. This study has defined design process of sponge campus planning in hilly areas to a certain degree and provided a research basis for sponge campus planning and construction of universities, setting up a typical example and driving effects on solving urban local flooding problem and rainfall resource utilization in hilly areas.

L'objet de cet article est de ramener les regards sur le fait touristique et sur les circonstances qui l'entourent. Celles‐ci sont très diverses. Il en est qui intéressent l'histoire diplomatique des Etats (telle la tension entre le Gouvernement français et les vallées d'Andorre dans l'été 1953, agissant négativement sur la fréquentation touristique estivale de ce coin des Pyrénées). D'autres sont en relation avec des faits d'actualité politique (la crise de Trieste en novembre 1953 a rempli les hôtels de Viareggio de touristes américains). Une mesure administrative (l'avancement des dates de vacances scolaires en France de 15 jours en 1953) se répercute sur le chiffre d'affaires des hôteliers bretons. Le progrès technique est partout décisif: l'ouverture d'une route pour aller, en Suisse, de Viège à Saas‐Fee change radicalement l'équation touristique de cette station. Quelque fois le tourisme repousse le tourisme: la création de services touristes aériens entre Paris et la Scandinavie porte tort aux services de première classe et conduit la compagnie aérienne à les rétablir (octobre 1953).

This paper is a study of the current trends and conditions of electronic resources for Chinese studies, based on a recent survey on the Internet of 29 Chinese libraries in North America and eight Chinese libraries in China, Taiwan and Hong Kong. The survey discussed current electronic resources for Chinese studies, with a union list of major Chinese language databases currently used in libraries in Asia and the US. Current views on the use and development of electronic resources for Chinese studies were summarised.

In the process of vigorously promoting urbanization, the city development became a new driving force for China's prosperity. To comprehensively analyze the urban regional innovation system, the typical urban city was taken as an empirical sample to consider as an urban regional innovation system. The fuzzy comprehensive evaluation method was used to evaluate the operation of typical urban regional innovation system, combined the cluster analysis and Bayesian discrimination for the research and analysis. The results showed that the evaluation of regional innovation system was a national innovation strategy. Therefore, the model provides an important evidence for the urban innovative development. The proposed targeted innovation development strategy is conducive to grasp the advantages and disadvantages of the typical urban regional innovation system construction as a whole. The analysis of the structural change layers and sub-distribution of urban regional innovation effectiveness helps to clarify the stage of urban development.

Investigation of the anomalies associated with crashes and jackpots in the Chinese stock market.

We propose a logit model to predict the events of crashes and jackpots in the Chinese stock market. The model introduces a new variable of the price-to-sales ratio and takes into account the market states, Up and Down.

The anomalies associated with crashes and jackpots are not related to variations in economic conditions, but are associated with limits to arbitrage. High-liquidity stocks have strong mispricing effects. The institutions’ speculative trading will push liquid stock prices further away from their fundamentals but avoid buying illiquid stocks with a higher probability of price crashes and jackpots.

We propose a logit model to predict the extreme events of both crash and jackpot in the Chinese stock market. Our model effectively disentangles from CRASHP and JACKP. Compared with the traditional model, it substantially enhances in-sample and out-sample predictions. Based on the predictions of the extreme events, we find two strong and robust pricing effects associated with ex ante CRASHP and JACKP in the Chinese stock market.

The purpose of this paper is to offer novel insights into: knowledge of proto-feminism through description and analysis of the rule of the seventh century female Emperor Wu Zetian; postcolonial theory by revealing the existence and proto-feminist activities of a non-western female leader; and the literature on gender and invisibility through a study of a leading figure that is relatively unknown to western feminists and is even, in feminist terms, something of a neglected figure.

In order to examine Wu’s proto-feminist practices as recorded in historical materials, we use critical hermeneutics as a tool for textual interpretation, through the following four stages: choosing texts from historical records and writings of Wu; analyzing the historical sociocultural context; analyzing the relationship between the text and the context; and offering a conceptual framework as a richer explanation.

Wu’s life activities demonstrate proto-feminism in late seventh century China in at least four aspects: gender equality in sexuality, in social status, in politics, and women’s pursuit of power and leadership.

Future research may dig into the paradox of Wu’s proto-feminist practices, the relationship between organizational power and feminism/proto-feminism, and the ways in which Wu’s activities differ from other powerful women across cultures, etc.

The study encourages a rethink of women and leadership style in non-western thought.

The study supports Calás and Smircich’s 2005 call for greater understanding of feminist thought outside of western thought and a move to transglobal feminism.

This study recovers long lost stories of women leadership that are “invisible” in many ways in the historical narratives, and contributes to postcolonial feminism by revealing the existence of indigenous proto-feminist practice in China long before western-based feminism and postcolonial feminism emerged.
