Explore a new book discovery experience in the public library
No full textNowadays, a public library is no longer a place just for the collection of books. It has offered multiple functions to take the responsibility of being a public cultural institution for all citizens. However, in the Netherlands, libraries are losing their members, especially young adults. With the development of technology, a public library is no longer the only choice for books. Libraries are encountering a challenge to attract young people back. They need to strive for providing new kinds of public services to attract this potential new audience.Westfriese Bibliotheken is one of these libraries which has 10 decentralized community libraries in 6 places in the north of the Netherlands. Westfriese Bibliotheken is facing a challenge to reach a bigger group of the generation of youngsters who think a public library is a dull place to go. To narrow down the scope, the book discovery experience for young adults between 18-25 years old was focused. Augmented reality as the technology this project worked with has been proved to benefit the library context.Hence, the objective of this thesis is to explore a new book discovery experience for young adults in the public library in Stede Broec.From the theoretical study (chapter 2) about the book discovery behavior, the behavior pattern was investigated and worked as the design requirements. User research (chapter 3) was conducted to understand the current book discovery experience in the context through contextmapping. It discovered users' concerns and expectations about the book discovery experience. Moreover, the opportunity of this project: designing a new book discovery experience to facilitate serendipity was concluded based on user research findings. Under the framework of the serendipity theory (chapter 4), design opportunities for facilitating serendipity in the current library were gathered. The study on augmented reality (chapter 5) helped to define design qualities and technologies that this project can make use of.With the research insights, a design goal with three design qualities (fascinating, playful, and inviting) and relevant design requirements were formulated (chapter 6). They contributed as a guideline to the design solution.Ideas were gathered through a creative session and based on these ideas three initial concepts were generated. Concepts were evaluated and iterated with users, clients, and fellow students. The final design outcome is a phone-based AR application with two main parts: exploring and browsing parts. It offers both basic and additional information about books to stimulate users to experience serendipity in the public library. Finally, an evaluation test was conducted to validate if the final design can fulfill the design goal. The final design achieves a good usability and desirability performance evaluated by 6 participants in the library. The evaluation test demonstrated that the additional information about books and interaction between the physical and digital world can let users feel fascinated, invited, and playful during the book discovery experience.Design for Interactio
Investigation into the Promotion and Instruction of Chinese Traditional Music in Liaocheng Peiwen School of Peking University
No full textThis research investigates the promotion and instruction of Chinese Traditional music in Liaocheng Peiwen School of Peking University. The first author, an alum with a decade of pedagogical experience, examined the challenges faced by private schools in providing tailored regulatory frameworks for Chinese Traditional music education. We share practical experience, drawing on the successful establishment of the school-based course "Chinese Folk Music and Geography." As the course is offered each year during the geography exam for students in their second year of junior high school, singing folk songs while learning geography enables students to explore China's beautiful landscapes while broadening their horizons. Students can understand the connection between folk music and geography, assisting their preparation for the exam

Metal Phosphides Derived from Hydrotalcite Precursors toward the Selective Hydrogenation of Phenylacetylene
No full text
We report a new synthetic strategy for the fabrication of several supported nickel phosphides (Ni12P5, Ni2P, and NiP2) with particle size ranging from 5 to 15 nm via a two-step procedure: preparation of supported Ni particles from layered double hydroxide precursors, followed by a further reaction with a certain amount of red phosphorus. The selective hydrogenation of phenylacetylene over these metal phosphides was evaluated, and the as-prepared Ni2P/Al2O3 catalyst shows a much higher selectivity to styrene (up to 88.2%) than Ni12P5/Al2O3 (48.0%), NiP2/Al2O3 (65.9%), and Ni/Al2O3 (0.7%) catalysts. EXAFS and in situ IR measurements reveal that the incorporation of P increases the bond length of Ni-Ni, which imposes a key influence on the adsorption state of alkene intermediates: as the Ni-Ni bond length extends to 0.264 nm, the alkene intermediate undergoes di-pi(C=C) adsorption, facilitating its desorption and the resulting enhanced selectivity. Moreover, electron transfer occurs from Ni to P, as confirmed by EXAFS, XPS, and in situ CO-IR experiment, in which the positively charged Ni reduces the desorption energy of alkene and thus improves the reaction selectivity.</p
A method for rapid demolition of a crossline arch bridge: a case study
No full textAbstract To reduce the adverse impact of demolition of the symmetrical rigid frame arch bridge overcrossing the highway with over-saturated traffic flow, a rapid demolition method based on the Self-Propelled Modular Transporter (SPMT) technique was developed in this study. The calculation formulae for reaction forces of the supporting brackets, as well as driving force and stability of SPMTs, were derived by analyzing the stability, synchronization, and influencing parameters of the cut bridge body—transport system. In addition, a monitoring system during the whole process was developed to ensure the demolition safety. An application of demolishing a crossline symmetrical rigid frame arch bridge in China within 5 h has been presented. The results showed that the proposed method can be successfully applied in real projects, leading to significant reduction in traffic impact, energy consumption, and environmental pollution

No full textBritish romantic poets generally illustrate distinctive geographical writing characteristics. Among them, John Keats is a representative in composing geographical space from a multi-dimensional perspective, either real or imaginary, thus illustrating the natural aesthetic characteristics of his poetry and the poet’s own humanistic thoughts and political concerns. In his poems, Keats not only wrote about the landscape of English natural geographical appearance, including forests, grasslands, etc., which highlighted his love for Britain and pride in folk customs, but also focused on the human landscape represented by castles and churches, which highlighted the central position of England within Great Britain and the anticipation of integrating Scotland under English control. Keats is not confined to a particular moment or a scene, but detached from reality and creating fantasy to incorporate elements of magical mythology in order to fictionalize the natural geographic environment including nature, river, mountains and human geography like castles, thus highlighting his Hellenized Britain and publicizing the civilized image of the Great Britain. On the other hand, he also highlighted the rationality and order of Britain through the mapping of the East, and provided a rational explanation for its Eastern colonization
Discussion on the Operation Mode of Public-Private Elderly Institutions under the High-Quality Development of Elderly Services
No full textIn the context of high-quality development of senior care services, public-private-run senior care institutions are a new type of senior care institution operation mode, which integrates the advantages of traditional public and private senior care institutions, circumvents the drawbacks of the two, and provides a new path choice for alleviating the diversified senior care needs of the elderly. By analyzing the internal and external advantages of the development mode of public-private elderly care institutions, as well as the threats and challenges faced in the development process. The study found that public-private elderly care institutions have the advantages of integrating elderly care resources and tending to be more specialized and diversified, but public-private elderly care institutions are also vulnerable to profit-driven, deviating from the positioning of public welfare; the lack of professional talents and other problems. The strategy of integration of industry and education should be further implemented to ensure the supply of professional nursing talents; strengthen the government's supervision and management, and establish a mechanism for the exit and introduction of public-private elderly care institutions. Further optimize the operation mode of public-private elderly care institutions, provide diversified choices of elderly care services, and help the high-quality development of elderly care services
The Recent Development of Multifunctional Gold Nanoclusters in Tumor Theranostic and Combination Therapy
No full textThe rising incidence and severity of malignant tumors threaten human life and health, and the current lagged diagnosis and single treatment in clinical practice are inadequate for tumor management. Gold nanoclusters (AuNCs) are nanomaterials with small dimensions (≤3 nm) and few atoms exhibiting unique optoelectronic and physicochemical characteristics, such as fluorescence, photothermal effects, radiosensitization, and biocompatibility. Here, the three primary functions that AuNCs play in practical applications, imaging agents, drug transporters, and therapeutic nanosystems, are characterized. Additionally, the promise and remaining limitations of AuNCs for tumor theranostic and combination therapy are discussed. Finally, it is anticipated that the information presented herein will serve as a supply for researchers in this area, leading to new discoveries and ultimately a more widespread use of AuNCs in pharmaceuticals
