trajectory planning of robots and determines the operational quality directly. An adaptive acceleration and deceleration motion planning based on trigonometric functions for the end-effector of 6-DOF robots in Cartesian coordinate system is proposed in this paper. This method not only achieves the smooth translation motion and rotation motion by constructing a continuous jerk model, but also automatically adjusts the parameters of trigonometric functions according to the variable inputs and the kinematic constraints.

This study aims to explore whether these events have had an impact on the university preferences of high school students. To delve into these questions, this research immerses itself in the forefront of Hong Kong's educational landscape. It encompasses field studies, interviews, and questionnaires administered to a diverse range of Hong Kong students, as well as their parents and teachers. The findings uncover that the majority of local Hong Kong students and parents possess a limited understanding of mainland China, and this perception has further soured since 2019. Interestingly, the inclination towards pursuing overseas education, particularly in countries like the UK and Australia, has experienced a steady rise. This trend persists despite the fact that esteemed Chinese universities extend preferential admissions policies to Hong Kong students. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=higher%20education" title="higher education">higher education</a>, <a href="https://publications.waset.org/abstracts/search?q=university%20choices" title=" university choices"> university choices</a>, <a href="https://publications.waset.org/abstracts/search?q=educational%20sociology" title=" educational sociology"> educational sociology</a>, <a href="https://publications.waset.org/abstracts/search?q=education%20in%20Hongkong" title=" education in Hongkong"> education in Hongkong</a> </p> <a href="https://publications.waset.org/abstracts/172226/examining-the-decision-making-process-of-hong-kong-high-school-students-regarding-university-choices-after-2019" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172226.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">141</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">16</span> The Influence of Thomson Effect on the Performance of N-Type Skutterudite Thermoelement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anbang%20Liu">Anbang Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Huaqing%20Xie"> Huaqing Xie</a>, <a href="https://publications.waset.org/abstracts/search?q=Zihua%20Wu"> Zihua Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiaoxiao%20Yu"> Xiaoxiao Yu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuanyuan%20Wang"> Yuanyuan Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to the temperature-dependence and mutual coupling of thermoelectric parameters, the Thomson effect always exists, which is derived from temperature gradients during thermoelectric conversion. The synergistic effect between the Thomson effect and non-equilibrium heat transport of charge carriers leads to local heat absorption or release in thermoelements, thereby affecting its power generation performance and conversion efficiency. This study verified and analyzed the influence and mechanism of the Thomson effect on N-type skutterudite thermoelement through quasi-steady state testing under approximate vacuum conditions. The results indicate the temperature rise/fall of N-type thermoelement at any position is affected by Thomson heat release/absorption. Correspondingly, the Thomson effect also contributes advantageously/disadvantageously to the output power of N-type skutterudite thermoelement when the Thomson coefficients are positive/negative. In this work, the output power can be promoted or decreased maximally by more than 27% due to the presence of Thomson heat when the absolute value of the Thomson coefficient is around 36 μV/℃. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thomson%20effect" title="Thomson effect">Thomson effect</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20transport" title=" heat transport"> heat transport</a>, <a href="https://publications.waset.org/abstracts/search?q=thermoelectric%20conversion" title=" thermoelectric conversion"> thermoelectric conversion</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20simulation" title=" numerical simulation"> numerical simulation</a> </p> <a href="https://publications.waset.org/abstracts/177667/the-influence-of-thomson-effect-on-the-performance-of-n-type-skutterudite-thermoelement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/177667.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">67</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">15</span> Influential Factors Affecting the Creativity Scientific Problem Finding Ability of Social Science Ph.D. Students</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yuanyuan%20Song">Yuanyuan Song</a> </p> <p class="card-text"><strong>Abstract:</strong></p> For Ph.D. students, the skill of formulating incisive inquiries holds immense importance, as adept questioning can significantly unravel research complexities.

Treating psychological flexibility as a form of multicultural competence, we conducted five studies to construct the lay concept of psychological flexibility (Study 1 and 2) and test the association between psychological flexibility and multicultural adaptation (Study 3-5). In Study 1, we first identified the components of psychological flexibility by prototype analysis among lay Chinese (N = 165) and American (N = 165). In Study 2, we examined the convergent validity of the lay concept of psychological flexibility consisted with hypothesized structures via survey among Chinese (N = 172) and American participants (N = 165). Then, we examined the relationship between psychological flexibility and multicultural orientation in American and Chinese contexts (Study 3, N = 6245), and tested the influence of experimentally-manipulated psychological flexibility on foreign cultural accommodation (Study 4 N = 409; Study 5, N = 320). The results showed, higher flexibility was accompanied by higher cognitive flexibility, emotion reappraisal, resilience, and openness to experience, and lower need for cognition closure; besides, people with high psychological flexible turned out to have stronger multicultural orientation and better multicultural adaptations. Our research highlights the importance of psychological flexibility in multicultural situations and extends the understanding of the relationship between multicultural experience and well-being. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adaptation" title="adaptation">adaptation</a>, <a href="https://publications.waset.org/abstracts/search?q=psychological%20flexibility" title=" psychological flexibility"> psychological flexibility</a>, <a href="https://publications.waset.org/abstracts/search?q=multicultural%20competence" title=" multicultural competence"> multicultural competence</a>, <a href="https://publications.waset.org/abstracts/search?q=multicultural%20orientation" title=" multicultural orientation"> multicultural orientation</a> </p> <a href="https://publications.waset.org/abstracts/100923/lay-approach-of-psychological-flexibility-concept-prototype-and-its-application-in-multicultural-adaptation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100923.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">239</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">13</span> Evaluating the Performance of Existing Full-Reference Quality Metrics on High Dynamic Range (HDR) Video Content</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maryam%20Azimi">Maryam Azimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Amin%20Banitalebi-Dehkordi"> Amin Banitalebi-Dehkordi</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuanyuan%20Dong"> Yuanyuan Dong</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahsa%20T.%20Pourazad"> Mahsa T.

The objective of this study is to compare the performance of the existing full-reference LDR and HDR video quality metrics on HDR content and identify the most effective one for HDR applications. To this end, a new HDR video data set is created, which consists of representative indoor and outdoor video sequences with different brightness, motion levels and different representing types of distortions. The quality of each distorted video in this data set is evaluated both subjectively and objectively. The correlation between the subjective and objective results confirm that VIF quality metric outperforms all to their tested metrics in the presence of the tested types of distortions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=HDR" title="HDR">HDR</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20range" title=" dynamic range"> dynamic range</a>, <a href="https://publications.waset.org/abstracts/search?q=LDR" title=" LDR"> LDR</a>, <a href="https://publications.waset.org/abstracts/search?q=subjective%20evaluation" title=" subjective evaluation"> subjective evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=video%20compression" title=" video compression"> video compression</a>, <a href="https://publications.waset.org/abstracts/search?q=HEVC" title=" HEVC"> HEVC</a>, <a href="https://publications.waset.org/abstracts/search?q=video%20quality%20metrics" title=" video quality metrics"> video quality metrics</a> </p> <a href="https://publications.waset.org/abstracts/18171/evaluating-the-performance-of-existing-full-reference-quality-metrics-on-high-dynamic-range-hdr-video-content" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18171.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">524</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12</span> The Efficacy of Contractual Governance on Task and Relationship Conflict in Construction Projects</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jingya%20You">Jingya You</a>, <a href="https://publications.waset.org/abstracts/search?q=Yongqiang%20Chen"> Yongqiang Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuanyuan%20Hua"> Yuanyuan Hua</a>, <a href="https://publications.waset.org/abstracts/search?q=Wenqian%20Wang"> Wenqian Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Conflict is commonplace in construction projects, and construction projects always involve designing contracts between the owner and the contractor. However, how the contract affects the level of conflict between the owner and the contractor has not been elaborated. The purpose of this paper is to explain the effects of contractual complexity on the level of conflict, including task conflict and relationship conflict, and then to demonstrate the moderating role played by the interdependence between the owner and the contractor. Using data from owners and general contractors in the Chinese construction industry, this research reveals that contractual control will reduce relationship conflict. Contractual coordination will also reduce relationship conflict by the mediating effect of task conflict. Besides, under high joint interdependence, the positive relationship between task conflict and relationship conflict is strengthened, while high interdependence asymmetry has effects on weakening the relationship between task conflict and relationship conflict. The findings provide guidance for contract designers to draft suitable contracts in order to effectively deal with conflict. Additionally, this research implies that project managers should highlight the importance of contract in conflict management. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=construction%20projects" title="construction projects">construction projects</a>, <a href="https://publications.waset.org/abstracts/search?q=contract%20governance" title=" contract governance"> contract governance</a>, <a href="https://publications.waset.org/abstracts/search?q=interdependence" title=" interdependence"> interdependence</a>, <a href="https://publications.waset.org/abstracts/search?q=relationship%20conflict" title=" relationship conflict"> relationship conflict</a>, <a href="https://publications.waset.org/abstracts/search?q=task%20conflict" title=" task conflict"> task conflict</a> </p> <a href="https://publications.waset.org/abstracts/100047/the-efficacy-of-contractual-governance-on-task-and-relationship-conflict-in-construction-projects" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100047.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">218</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">11</span> Simulation-Based Investigation of Ferroresonance in Different Transformer Configurations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=George%20Eduful">George Eduful</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuanyuan%20Fan"> Yuanyuan Fan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Abu-Siada"> Ahmed Abu-Siada</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ferroresonance poses a substantial threat to the quality and reliability of power distribution systems due to its inherent characteristics of sustained overvoltages and currents. This paper aims to enhance the understanding and reduce the ferroresonance threat by investigating the susceptibility of different transformer configurations using MATLAB/Simulink simulations. To achieve this, four 200 kVA transformers with different vector groups (D-Yn, Yg-Yg, Yn-Yn, and Y-D11) and core types (3-limb, 5-limb, single-phase) were systematically exposed to controlled ferroresonance conditions. The impact of varying the length of the 11 kV cable connected to the transformers was also examined. Through comprehensive voltage, current, and total harmonic distortion analyses, the performance of each configuration was evaluated and compared. The results of the study indicate that transformers with Y-D11 and Yg-Yg configurations exhibited lower susceptibility to ferroresonance, in comparison to those with D-Y11 and Yg-Yg configurations. This implies that the Y-D11 and Yg-Yg transformers are better suited for applications with high risks of ferroresonance. The insights provided by this study are of significant value for the strategic selection and deployment of transformers in power systems, particularly in settings prone to ferroresonance. By identifying and recommending transformer configurations that demonstrate better resilience, this paper contributes to enhancing the overall robustness and reliability of power grid infrastructure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=about%20cable-connected" title="about cable-connected">about cable-connected</a>, <a href="https://publications.waset.org/abstracts/search?q=core%20type" title=" core type"> core type</a>, <a href="https://publications.waset.org/abstracts/search?q=ferroresonance" title=" ferroresonance"> ferroresonance</a>, <a href="https://publications.waset.org/abstracts/search?q=over%20voltages" title=" over voltages"> over voltages</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20transformer" title=" power transformer"> power transformer</a>, <a href="https://publications.waset.org/abstracts/search?q=vector%20group" title=" vector group"> vector group</a> </p> <a href="https://publications.waset.org/abstracts/189176/simulation-based-investigation-of-ferroresonance-in-different-transformer-configurations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/189176.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">39</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10</span> Study on the Factors Influencing the Built Environment of Residential Areas on the Lifestyle Walking Trips of the Elderly</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Daming%20Xu">Daming Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuanyuan%20Wang"> Yuanyuan Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Abstract: Under the trend of rapid expansion of urbanization, the motorized urban characteristics become more and more obvious, and the walkability of urban space is seriously affected.

Therefore, it is of great practical significance to explore the impact of built environment on elderly people's daily walking trips at the settlement level for the construction of pedestrian-friendly settlements for the elderly. The study takes three typical settlements in Harbin Daoli District in three different periods as examples and obtains data on elderly people's walking trips and built environment characteristics through field research, questionnaire distribution, and internet data acquisition. Finally, correlation analysis and multinomial logistic regression model were applied to analyze the influence mechanism of built environment on elderly people's walkability based on the control of personal attribute variables in order to provide reference and guidance for the construction of walkability for elderly people in built environment in the future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=built%20environment" title="built environment">built environment</a>, <a href="https://publications.waset.org/abstracts/search?q=elderly" title=" elderly"> elderly</a>, <a href="https://publications.waset.org/abstracts/search?q=walkability" title=" walkability"> walkability</a>, <a href="https://publications.waset.org/abstracts/search?q=multinomial%20logistic%20regression%20model" title=" multinomial logistic regression model"> multinomial logistic regression model</a> </p> <a href="https://publications.waset.org/abstracts/164764/study-on-the-factors-influencing-the-built-environment-of-residential-areas-on-the-lifestyle-walking-trips-of-the-elderly" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164764.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">76</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9</span> Full-Spectrum Photo-thermal Conversion of Point-mode Cu₂O/TiN Plasmonic Nanofluids</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xiaoxiao%20Yu">Xiaoxiao Yu</a>, <a href="https://publications.waset.org/abstracts/search?q=Guodu%20He"> Guodu He</a>, <a href="https://publications.waset.org/abstracts/search?q=Zihua%20Wu"> Zihua Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuanyuan%20Wang"> Yuanyuan Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Huaqing%20Xie"> Huaqing Xie</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Core-shell composite structure is a common method to regulate the spectral absorption of nanofluids, but there occur complex preparation processes, which limit the applications in some fields, such as photothermal utilization and catalysis. This work proposed point-mode Cu₂O/TiN plasmonic nanofluids to regulate the spectral capturing ability and simplify the preparation process. Non-noble TiN nanoparticles with the localized surface plasmon resonance effect are dispersed in Cu₂O nanoparticles for forming a multi-point resonance source to enhance the spectral absorption performance. The experimental results indicate that the multiple resonance effect of TiN effectively improves the optical absorption and expands the absorption region. When the radius of Cu₂O nanoparticles is equal to 150nm, the optical absorption of point-mode Cu₂O/TiN plasmonic nanoparticles is best. Moreover, the photothermal conversion efficiency of Cu₂O/TiN plasmonic nanofluid can reach 97.5% at a volume fraction of 0.015% and an optical depth of 10mm. The point-mode nanostructure effectively enhances the optical absorption properties and greatly simplifies the preparation process of the composite nanoparticles, which can promote the application of multi-component photonic nanoparticles in the field of solar energy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solar%20energy" title="solar energy">solar energy</a>, <a href="https://publications.waset.org/abstracts/search?q=nanofluid" title=" nanofluid"> nanofluid</a>, <a href="https://publications.waset.org/abstracts/search?q=point-mode%20structure" title=" point-mode structure"> point-mode structure</a>, <a href="https://publications.waset.org/abstracts/search?q=Cu%E2%82%82O%2FTiN" title=" Cu₂O/TiN"> Cu₂O/TiN</a>, <a href="https://publications.waset.org/abstracts/search?q=localized%20surface%20plasmon%20resonance%20effect" title=" localized surface plasmon resonance effect"> localized surface plasmon resonance effect</a> </p> <a href="https://publications.waset.org/abstracts/177661/full-spectrum-photo-thermal-conversion-of-point-mode-cu2otin-plasmonic-nanofluids" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/177661.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">61</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8</span> The Influence of Superordinate Identity and Group Size on Group Decision Making through Discussion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lin%20Peng">Lin Peng</a>, <a href="https://publications.waset.org/abstracts/search?q=Jin%20Zhang"> Jin Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuanyuan%20Miao"> Yuanyuan Miao</a>, <a href="https://publications.waset.org/abstracts/search?q=Quanquan%20Zheng"> Quanquan Zheng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Group discussion and group decision-making have long been a topic of research interest. Traditional research on group decision making typically focuses on the strategies or functional models of combining members’ preferences to reach an optimal consensus. In this research, we want to explore natural process group decision making through discussion and examine relevant, influential factors--common superordinate identity shared by group and size of the groups. We manipulated the social identity of the groups into either a shared superordinate identity or different subgroup identities. We also manipulated the size to make it either a big (6-8 person) group or small group (3-person group). Using experimental methods, we found members of a superordinate identity group tend to modify more of their own opinions through the discussion, compared to those only identifying with their subgroups. Besides, members of superordinate identity groups also formed stronger identification with group decision--the results of group discussion than their subgroup peers. We also found higher member modification in bigger groups compared to smaller groups. Evaluations of decisions before and after discussion as well as group decisions are strongly linked to group identity, as members of superordinate group feel more confident and satisfied with both the results and decision-making process. Members’ opinions are more similar and homogeneous in smaller groups compared to bigger groups. This research have many implications for further research and applied behaviors in organizations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=group%20decision%20making" title="group decision making">group decision making</a>, <a href="https://publications.waset.org/abstracts/search?q=group%20size" title=" group size"> group size</a>, <a href="https://publications.waset.org/abstracts/search?q=identification" title=" identification"> identification</a>, <a href="https://publications.waset.org/abstracts/search?q=modification" title=" modification"> modification</a>, <a href="https://publications.waset.org/abstracts/search?q=superordinate%20identity" title=" superordinate identity"> superordinate identity</a> </p> <a href="https://publications.waset.org/abstracts/53349/the-influence-of-superordinate-identity-and-group-size-on-group-decision-making-through-discussion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53349.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">307</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7</span> Capitalizing on Differential Network Ties: Unpacking Individual Creativity from Social Capital Perspective</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yuanyuan%20Wang">Yuanyuan Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Chun%20Hui"> Chun Hui</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Drawing on social capital theory, this article discusses how individuals may utilize network ties to come up with creativity. Social capital theory elaborates how network ties enhances individual creativity from three dimensions: structural access, and relational and cognitive mechanisms. We categorize network ties into strong and weak in terms of tie strength. With less structural constraints, weak ties allow diverse and heterogeneous knowledge to prosper, further facilitating individuals to build up connections among diverse even distant ideas. On the other hand, strong ties with the relational mechanism of cooperation and trust may benefit the accumulation of psychological capital, ultimately to motivate and sustain creativity. We suggest that differential ties play different roles for individual creativity: Weak ties deliver informational benefit directly rifling individual creativity from informational resource aspect; strong ties offer solidarity benefits to reinforce psychological capital, which further inspires individual creativity engagement from a psychological viewpoint. Social capital embedded in network ties influence individuals’ informational acquisition, motivation, as well as cognitive ability to be creative. Besides, we also consider the moderating effects constraining the relatedness between network ties and creativity, such as knowledge articulability. We hypothesize that when the extent of knowledge articulability is low, that is, with low knowledge codifiability, and high dependency and ambiguity, weak ties previous serving as knowledge reservoir will not become ineffective on individual creativity. Two-wave survey will be employed in Mainland China to empirically test mentioned propositions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=network%20ties" title="network ties">network ties</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20capital" title=" social capital"> social capital</a>, <a href="https://publications.waset.org/abstracts/search?q=psychological%20capital" title=" psychological capital"> psychological capital</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge%20articulability" title=" knowledge articulability"> knowledge articulability</a>, <a href="https://publications.waset.org/abstracts/search?q=individual%20creativity" title=" individual creativity"> individual creativity</a> </p> <a href="https://publications.waset.org/abstracts/26207/capitalizing-on-differential-network-ties-unpacking-individual-creativity-from-social-capital-perspective" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26207.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">404</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6</span> Investigation on Solar Thermoelectric Generator Using D-Mannitol/Multi-Walled Carbon Nanotubes Composite Phase Change Materials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zihua%20Wu">Zihua Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yueming%20He"> Yueming He</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiaoxiao%20Yu"> Xiaoxiao Yu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuanyuan%20Wang"> Yuanyuan Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Huaqing%20Xie"> Huaqing Xie</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The match of Solar thermoelectric generator (STEG) and phase change materials (PCM) can enhance the solar energy storage and reduce environmental impact from the day-and-night transformation and weather changes. This work utilizes D-mannitol (DM) matrix as the suitable PCM for coupling with thermoelectric generator to achieve the middle-temperature solar energy storage performance at 165℃-167℃. DM/MWCNT composite phase change materials prepared by ball milling not only can keep a high phase change enthalpy of DM material but also have great photo-thermal conversion efficiency of 82%. Based on the self-made storage device container, the effect of PCM thickness on the solar energy storage performance is further discussed and analyzed. The experimental results prove that PCM-STEG coupling system can output more electric energy than pure STEG system because PCM can decline the heat transfer and storage thermal energy to further generate the electric energy through thermal-to-electric conversion when the light is removed. The increase of PCM thickness can reduce the heat transfer and enhance thermal storage, and then the power generation performance of PCM-STEG coupling system can be improved. As the increase of light intensity, the output electric energy of the coupling system rises accordingly, and the maximum amount of electrical energy can reach by 113.85 J at 1.6 W/cm2. The study of the PCM-STEG coupling system has certain reference for the development of solar energy storage and application. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solar%20energy" title="solar energy">solar energy</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20thermoelectric%20generator" title=" solar thermoelectric generator"> solar thermoelectric generator</a>, <a href="https://publications.waset.org/abstracts/search?q=phase%20change%20materials" title=" phase change materials"> phase change materials</a>, <a href="https://publications.waset.org/abstracts/search?q=solar-to-electric%20energy" title=" solar-to-electric energy"> solar-to-electric energy</a>, <a href="https://publications.waset.org/abstracts/search?q=DM%2FMWCNT" title=" DM/MWCNT"> DM/MWCNT</a> </p> <a href="https://publications.waset.org/abstracts/177662/investigation-on-solar-thermoelectric-generator-using-d-mannitolmulti-walled-carbon-nanotubes-composite-phase-change-materials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/177662.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">72</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5</span> Course Perceiving Differences among College Science Students from Various Cultures: A Case Study in the US</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yuanyuan%20Song">Yuanyuan Song</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: As we all know, culture plays a pivotal role in the realm of education, influencing study perceptions and outcomes. Nevertheless, there remains a need to delve into how culture specifically impacts the perception of courses. Therefore, the impact of culture on students' perceptions and academic performance is explored in this study. Drawing from cultural constructionism and conflict theories, it is posited that when students hailing from diverse cultures and backgrounds converge in the same classroom, their perceptions of course content may diverge significantly. This study seeks to unravel the tangible disparities and ascertain how cultural nuances shape students' perceptions of classroom content when encountering diverse cultural contexts within the same learning environment. Methodology: Given the diverse cultural backgrounds of students within the US, this study draws upon data collected from a course offered by a US college. In pursuit of answers to these inquiries, a qualitative approach was employed, involving semi-structured interviews conducted in a college-level science class in the US during 2023. The interviews encompassed approximately nine questions, spanning demographic particulars, cultural backgrounds, science learning experiences, academic outcomes, and more. Participants were exclusively drawn from science-related majors, with each student originating from a distinct cultural context. All participants were undergraduates, and most of them were from eighteen to twenty-five years old, totaling six students who attended the class and willingly participated in the interviews. The duration of each interview was approximately twenty minutes. Results: The findings gleaned from the interview data underscore the notable impact of varying cultural contexts on students' perceptions. This study argues that female science students, for instance, are influenced by gender dynamics due to the predominant male presence in science majors, creating an environment where female students feel reticent about expressing themselves in public. Students of East Asian origin exhibit a stronger belief in the efficacy of personal efforts when contrasted with their North American counterparts. Minority students indicated that they grapple with integration into the predominantly white mainstream society, influencing their eagerness to engage in classroom activities that are conducted by white professors. All of them emphasized the importance of learning science. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multiculture%20education" title="multiculture education">multiculture education</a>, <a href="https://publications.waset.org/abstracts/search?q=educational%20sociology" title=" educational sociology"> educational sociology</a>, <a href="https://publications.waset.org/abstracts/search?q=educational%20equality" title=" educational equality"> educational equality</a>, <a href="https://publications.waset.org/abstracts/search?q=STEM%20education" title=" STEM education"> STEM education</a> </p> <a href="https://publications.waset.org/abstracts/172163/course-perceiving-differences-among-college-science-students-from-various-cultures-a-case-study-in-the-us" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172163.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">60</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4</span> Angiomotin Regulates Integrin Beta 1-Mediated Endothelial Cell Migration and Angiogenesis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yuanyuan%20Zhang">Yuanyuan Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yujuan%20Zheng"> Yujuan Zheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Giuseppina%20Barutello"> Giuseppina Barutello</a>, <a href="https://publications.waset.org/abstracts/search?q=Sumako%20Kameishi"> Sumako Kameishi</a>, <a href="https://publications.waset.org/abstracts/search?q=Kungchun%20Chiu"> Kungchun Chiu</a>, <a href="https://publications.waset.org/abstracts/search?q=Katharina%20Hennig"> Katharina Hennig</a>, <a href="https://publications.waset.org/abstracts/search?q=Martial%20Balland"> Martial Balland</a>, <a href="https://publications.waset.org/abstracts/search?q=Federica%20Cavallo"> Federica Cavallo</a>, <a href="https://publications.waset.org/abstracts/search?q=Lars%20Holmgren"> Lars Holmgren</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Angiogenesis describes that new blood vessels migrate from pre-existing ones to form 3D lumenized structure and remodeling. During directional migration toward the gradient of pro-angiogenic factors, the endothelial cells, especially the tip cells need filopodia to sense the environment and exert the pulling force. Of particular interest are the integrin proteins, which play an essential role in focal adhesion in the connection between migrating cells and extracellular matrix (ECM). Understanding how these biomechanical complexes orchestrate intrinsic and extrinsic forces is important for our understanding of the underlying mechanisms driving angiogenesis. We have previously identified Angiomotin (Amot), a member of Amot scaffold protein family, as a promoter for endothelial cell migration in vitro and zebrafish models. Hence, we established inducible endothelial-specific Amot knock-out mice to study normal retinal angiogenesis as well as tumor angiogenesis. We found that the migration ratio of the blood vessel network to the edge was significantly decreased in Amotec- retinas at postnatal day 6 (P6). While almost all the Amot defect tip cells lost migration advantages at P7. In consistence with the dramatic morphology defect of tip cells, there was a non-autonomous defect in astrocytes, as well as the disorganized fibronectin expression pattern correspondingly in migration front. Furthermore, the growth of transplanted LLC tumor was inhibited in Amot knockout mice due to fewer vasculature involved. By using MMTV-PyMT transgenic mouse model, there was a significantly longer period before tumors arised when Amot was specifically knocked out in blood vessels. In vitro evidence showed that Amot binded to beta-actin, Integrin beta 1 (ITGB1), Fibronectin, FAK, Vinculin, major focal adhesion molecules, and ITGB1 and stress fibers were distinctly induced by Amot transfection. Via traction force microscopy, the total energy (force indicater) was found significantly decreased in Amot knockdown cells. Taken together, we propose that Amot is a novel partner of the ITGB1/Fibronectin protein complex at focal adhesion and required for exerting force transition between endothelial cell and extracellular matrix. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=angiogenesis" title="angiogenesis">angiogenesis</a>, <a href="https://publications.waset.org/abstracts/search?q=angiomotin" title=" angiomotin"> angiomotin</a>, <a href="https://publications.waset.org/abstracts/search?q=endothelial%20cell%20migration" title=" endothelial cell migration"> endothelial cell migration</a>, <a href="https://publications.waset.org/abstracts/search?q=focal%20adhesion" title=" focal adhesion"> focal adhesion</a>, <a href="https://publications.waset.org/abstracts/search?q=integrin%20beta%201" title=" integrin beta 1"> integrin beta 1</a> </p> <a href="https://publications.waset.org/abstracts/72725/angiomotin-regulates-integrin-beta-1-mediated-endothelial-cell-migration-and-angiogenesis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72725.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">237</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3</span> Life Cycle Carbon Dioxide Emissions from the Construction Phase of Highway Sector in China</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yuanyuan%20Liu">Yuanyuan Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuanqing%20Wang"> Yuanqing Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Di%20Li"> Di Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Carbon dioxide (CO2) emissions mitigation from road construction activities is one of the potential pathways to deal with climate change due to its higher use of materials, machinery energy consumption, and high quantity of vehicle and equipment fuels for transportation and on-site construction activities. Aiming to assess the environmental impact of the road infrastructure construction activities and to identify hotspots of emissions sources, this study developed a life-cycle CO2 emissions assessment framework covering three stages of material production, to-site and on-site transportation under the guidance of the principle of LCA ISO14040. Then streamlined inventory analysis on sub-processes of each stage was conducted based on the budget files from cases of highway projects in China. The calculation results were normalized into functional unit represented as ton per km per lane. Then a comparison between the amount of emissions from each stage, and sub-process was made to identify the major contributor in the whole highway lifecycle. In addition, the calculating results were used to be compared with results in other countries for understanding the level of CO2 emissions associated with Chinese road infrastructure in the world. The results showed that materials production stage produces the most of the CO2 emissions (for more than 80%), and the production of cement and steel accounts for large quantities of carbon emissions. Life cycle CO2 emissions of fuel and electric energy associated with to-site and on-site transportation vehicle and equipment are a minor component of total life cycle CO2 emissions from highway project construction activities. Bridges and tunnels are dominant large carbon contributor compared to the road segments. The life cycle CO2 emissions of road segment in highway project in China are slightly higher than the estimation results of highways in European countries and USA, about 1500 ton per km per lane. In particularly, the life cycle CO2 emissions of road pavement in majority cities all over the world are about 500 ton per km per lane. However, there is obvious difference between the cities when the estimation on life cycle CO2 emissions of highway projects included bridge and tunnel. The findings of the study could offer decision makers a more comprehensive reference to understand the contribution of road infrastructure to climate change, especially understand the contribution from road infrastructure construction activities in China. In addition, the identified hotspots of emissions sources provide the insights of how to reduce road carbon emissions for development of sustainable transportation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20dioxide%20emissions" title="carbon dioxide emissions">carbon dioxide emissions</a>, <a href="https://publications.waset.org/abstracts/search?q=construction%20activities" title=" construction activities"> construction activities</a>, <a href="https://publications.waset.org/abstracts/search?q=highway" title=" highway"> highway</a>, <a href="https://publications.waset.org/abstracts/search?q=life%20cycle%20assessment" title=" life cycle assessment"> life cycle assessment</a> </p> <a href="https://publications.waset.org/abstracts/70022/life-cycle-carbon-dioxide-emissions-from-the-construction-phase-of-highway-sector-in-china" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70022.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">269</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> Patterns and Predictors of Intended Service Use among Frail Older Adults in Urban China</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yuanyuan%20Fu">Yuanyuan Fu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background and Purpose: Along with the change of society and economy, the traditional home function of old people has gradually weakened in the contemporary China. Acknowledging these situations, to better meet old people’s needs on formal services and improve the quality of later life, this study seeks to identify patterns of intended service use among frail old people living in the communities and examined determinants that explain heterogeneous variations in old people’s intended service use patterns. Additionally, this study also tested the relationship between culture value and intended service use patterns and the mediating role of enabling factors in terms of culture value and intended service use patterns. Methods：Participants were recruited from Haidian District, Beijing, China in 2015. The multi-stage sampling method was adopted to select sub-districts, communities and old people aged 70 years old or older. After screening, 577 old people with limitations in daily life, were successfully interviewed. After data cleaning, 550 samples were included for data analysis. This study establishes a conceptual framework based on the Anderson Model (including predisposing factors, enabling factors and need factors), and further developed it by adding culture value factors (including attitudes towards filial piety and attitudes towards social face). Using a latent class analysis (LCA), this study classifies overall patterns of old people’s formal service utilization. Fourteen types of formal services were taken into account, including housework, voluntary support, transportation, home-delivered meals, and home-delivery medical care, elderly’s canteen and day-care center/respite care and so on. Structural equation modeling (SEM) was used to examine the direct effect of culture value on service use pattern, and the mediating effect of the enabling factors. Results: The LCA classified a hierarchical structure of service use patterns: multiple intended service use (N=69, 23%), selective intended service use (N=129, 23%), and light intended service use (N=352, 64%). Through SEM, after controlling predisposing factors and need factors, the results showed the significant direct effect of culture value on older people’s intended service use patterns. Enabling factors had a partial mediation effect on the relationship between culture value and the patterns. Conclusions and Implications: Differentiation of formal services may be important for meeting frail old people’s service needs and distributing program resources by identifying target populations for intervention, which may make reference to specific interventions to better support frail old people. Additionally, culture value had a unique direct effect on the intended service use patterns of frail old people in China, enriching our theoretical understanding of sources of culture value and their impacts. The findings also highlighted the mediation effects of enabling factors on the relationship between culture value factors and intended service use patterns. This study suggests that researchers and service providers should pay more attention to the important role of culture value factors in contributing to intended service use patterns and also be more sensitive to the mediating effect of enabling factors when discussing the relationship between culture value and the patterns. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=frail%20old%20people" title="frail old people">frail old people</a>, <a href="https://publications.waset.org/abstracts/search?q=intended%20service%20use%20pattern" title=" intended service use pattern"> intended service use pattern</a>, <a href="https://publications.waset.org/abstracts/search?q=culture%20value" title=" culture value"> culture value</a>, <a href="https://publications.waset.org/abstracts/search?q=enabling%20factors" title=" enabling factors"> enabling factors</a>, <a href="https://publications.waset.org/abstracts/search?q=contemporary%20China" title=" contemporary China"> contemporary China</a>, <a href="https://publications.waset.org/abstracts/search?q=latent%20class%20analysis" title=" latent class analysis"> latent class analysis</a> </p> <a href="https://publications.waset.org/abstracts/65009/patterns-and-predictors-of-intended-service-use-among-frail-older-adults-in-urban-china" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65009.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">226</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Centrality and Patent Impact: Coupled Network Analysis of Artificial Intelligence Patents Based on Co-Cited Scientific Papers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xingyu%20Gao">Xingyu Gao</a>, <a href="https://publications.waset.org/abstracts/search?q=Qiang%20Wu"> Qiang Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuanyuan%20Liu"> Yuanyuan Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yue%20Yang"> Yue Yang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the era of the knowledge economy, the relationship between scientific knowledge and patents has garnered significant attention. Understanding the intricate interplay between the foundations of science and technological innovation has emerged as a pivotal challenge for both researchers and policymakers. This study establishes a coupled network of artificial intelligence patents based on co-cited scientific papers. Leveraging centrality metrics from network analysis offers a fresh perspective on understanding the influence of information flow and knowledge sharing within the network on patent impact. The study initially obtained patent numbers for 446,890 granted US AI patents from the United States Patent and Trademark Office’s artificial intelligence patent database for the years 2002-2020. Subsequently, specific information regarding these patents was acquired using the Lens patent retrieval platform. Additionally, a search and deduplication process was performed on scientific non-patent references (SNPRs) using the Web of Science database, resulting in the selection of 184,603 patents that cited 37,467 unique SNPRs. Finally, this study constructs a coupled network comprising 59,379 artificial intelligence patents by utilizing scientific papers co-cited in patent backward citations. In this network, nodes represent patents, and if patents reference the same scientific papers, connections are established between them, serving as edges within the network. Nodes and edges collectively constitute the patent coupling network. Structural characteristics such as node degree centrality, betweenness centrality, and closeness centrality are employed to assess the scientific connections between patents, while citation count is utilized as a quantitative metric for patent influence. Finally, a negative binomial model is employed to test the nonlinear relationship between these network structural features and patent influence. The research findings indicate that network structural features such as node degree centrality, betweenness centrality, and closeness centrality exhibit inverted U-shaped relationships with patent influence. Specifically, as these centrality metrics increase, patent influence initially shows an upward trend, but once these features reach a certain threshold, patent influence starts to decline. This discovery suggests that moderate network centrality is beneficial for enhancing patent influence, while excessively high centrality may have a detrimental effect on patent influence. This finding offers crucial insights for policymakers, emphasizing the importance of encouraging moderate knowledge flow and sharing to promote innovation when formulating technology policies. It suggests that in certain situations, data sharing and integration can contribute to innovation. Consequently, policymakers can take measures to promote data-sharing policies, such as open data initiatives, to facilitate the flow of knowledge and the generation of innovation. Additionally, governments and relevant agencies can achieve broader knowledge dissemination by supporting collaborative research projects, adjusting intellectual property policies to enhance flexibility, or nurturing technology entrepreneurship ecosystems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=centrality"
