Building environmental monitoring and compliance checking are important in ensuring environmental performance. The information required for monitoring and checking is obtained from different data sources in different information systems. In this context, information sharing between stakeholders and the semantic interoperability that prevails with varying information systems are necessary. However, the implementation of information sharing and semantic interoperability can be a challenge. This paper proposes an ontology-based framework to support environmental monitoring and compliance checking under building information modeling (BIM) environment among different information systems. The framework integrates building information from BIM, environmental information provided by sensors, and regulatory information based on building regulations and design requirements. In this framework, four specific ontologies are developed to represent relevant knowledge. Building information is extracted from BIM and then converted, together with environmental information provided by sensors, into resource description framework format as ontology instances. The regulation clauses are transformed into SPARQL (SPARQL Protocol and RDF Query Language) rules. A case study is performed to apply the framework, and environmental monitoring and automated compliance checking are implemented in the context of a real distributed energy station project. The testing results validate the feasibility and effectiveness of the proposed framework.

Based on data of 286 Chinese cities from 2006 to 2015, the paper applies Difference-in-Difference (DID) model to investigate whether and how High-Speed Railway (HSR) influences the tourist arrivals. Empirical results suggest that 1) although HSR opening can significantly promote tourist arrivals, the multi-stage DID model indicates a time-lag effect of HSR on tourism. 2) The positive effects of HSR opening on tourist arrivals increase gradually. 3) Improving HSR frequency helps cities to attract more tourists. 4) The location of HSR station has no significant impact on tourist arrivals. 5) Compared with the ordinary station, the hub station of HSR in the city can attract more tourist arrivals through an enhanced network effect.

We report a tandem asymmetric aldehyde–alkyne–amine (A3) coupling-carboxylative cyclization sequence for the highly enantioselective synthesis of chiral N-aryl 2-oxazolidinones. This is a rare example of a multicatalyst-promoted asymmetric tandem reaction using CO2 as a C1 synthon. Notably, the copper species and ligand from the upstream A3 reaction are internally reused to facilitate the downstream silver-catalyzed carboxylative cyclization.

Methods: Twenty-eight patients with BCfollowingchemotherapyand40age-and education-matched healthy controls (HCs) were recruited in the current study. All participants underwent source memory tests and resting-state functional MRI scans. Individual whole-brain functional brain networks were constructed and analyzed using graph-based network approaches. Results: Compared with the HCs, the BC patients showed lower scores in the source memory tests ( P < 0.001).Graph-based analyses revealed that the patients showed higher absolute global and local efficiency (both P < 0.01) but lower normalized global and normalized local efficiency (both P < 0.001) compared with the HCs. Locally, several prefrontal, occipital, and parietal regions exhibited higher nodal efficiency and functional connectivity in the patients( P < 0.05, corrected). Finally, positive correlations were observed between normalized global efficiency and Mini-Mental State Examination scores (r = 0.398, P = 0.036) and between normalized local efficiency and the source memory scores (r = 0.497, P = 0.01) in the patients. Conclusion: Chemotherapy-treated BC is associated with abnormal organization of large-scale functional brain networks, which could account for source memory dysfunction in patients with BC.

The study examines whether and how social media use can be sources of political affects.It examines both positive/negative affects and discrete negative emotions.It finds civic and political participation were triggered by different affects.It proposes a mediation-moderation mode. Although the role of affects and emotions in political participation has attracted much scholarly attention, few studies have examined whether and how media and communications can be the sources of political affects. This study argues that social media are not only information channels; they can also be effective in communicating feelings and emotions. Social media use may contribute to political affects, which in turn impinge on civic and political participation. In addition, political affects may moderate the effects of social media use on political participation. Based on a survey of university students in Guangzhou, China (N=897), this study finds that, under Chinas networked authoritarianism, political communication via social media is related to positive affects toward the government and society, while connection with activists via social media is related to negative affect. Positive and negative affects have different impact on different types of participation. Negative affects strengthen the connection between social media use and participation. The roles of three discrete negative emotions anger, anxiety and fear are also explored.

The aim of this study was to investigate the relationships between depression and occurrence of chemotherapy induced prospective memory impairment in patients with breast cancer (BC).The 63 BC patients before and after chemotherapy were administered with the self-rating depression scale (SDS) and a battery of cognitive neuropsychological tests including event-based and time-based prospective memory (EBPM and TBPM, respectively) tasks. The changes in their prospective memory and cognitive neuropsychological characteristics before and after chemotherapy were compared. Compared with the scores before chemotherapy, the EBPM score exhibited a statistically significant difference after chemotherapy (t = 6.069, P 0.05). Further, compared with the patients without depression, the patients with depression exhibited a statistically significant difference in the EBPM score (t = -4.348, P 0.05). Post-chemotherapy, EBPM and overall cognitive functions in BC patients merged with depression were found to decline, while TBPM did not show a significant change, suggesting that the combination of chemotherapy and depression might be related with the occurrence of post-chemotherapy EBPM impairment.
