The study further identifies social structure and technological differences as pivotal factors impacting collaborative innovation, with both positive and negative effects fluctuating alongside changes in proximity dimensions.

To do so, we draw on surveys and interviews across multiple college campuses in Georgia, both to identify desirable characteristics for students and to catalog the WREAs they have participated in.

The intension of this research is to promote ecosystem services and avoid the mantle of so-called “green urbanism”. Hence, examining the dose-response relationship is essential to understanding the intricate interplay between residential greenery quantity and landscape preference. Drawing upon preference assessment data from multiple neighborhoods with 30 typical scenes (n = 147), we employ Kaplan's landscape preference matrix (KLPM) to quantify the spatial distribution of greenery and individuals' preference assessment from the perspectives of Mystery, Coherence, Legibility, and Complexity. Results from multiple and ridge regressions indicate that the dose-response curve follows a polynomial shape, with landscape preferences reaching a threshold as the NDVI value increased from 0.35 to 0.42. Beyond the threshold, the trend of landscape preference levels tapers off and eventually plateaus. Therefore, the conclusion of our cross-sectional experiment adequately reflects the threshold effect of landscape preference toward greenery quantity. Furthermore, the weight of Mystery, Coherence, and Legibility in KLPM all showed a positive strong correlation, but the dose-response relationship cannot be fully explained by Complexity. These results inform how designers can more effectively promote optimal doses of nearby nature to circumvent worldwide overheated \"Garden City” initiatives.</p></div>","PeriodicalId":48396,"journal":{"name":"Applied Geography","volume":"170 ","pages":"Article 103357"},"PeriodicalIF":4.0,"publicationDate":"2024-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141942425","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results show that MGWR accurately quantifies the spatial effect. Meanwhile, the important TOD variables (integrated transit index, land use entropy, overall walkability) have positive effects on housing rents, which show spatial heterogeneity. Moreover, the premium effect of TOD station areas with a smaller proportion of residential and commercial land and a larger proportion of educational and cultural facilities is higher. Furthermore, in TOD station areas where transportation supply capacity is high but urban development is lagging, land use entropy and overall walkability have a strong influence on housing rents. Based on the study's results, we offer three recommendations for implementing TOD practices into integrated transportation and land use planning.
